Strengthening Public Health and Primary Care
Collaboration Through Electronic Health Records
Electronic health records
(EHRs) have great potential
to serve as a catalyst for
more effective coordina-
tion between public health
departments and primary
care providers (PCP) in
maintaining healthy com-
munities.
As a system for docu-
menting patient health data,
EHRs can be harnessed to
improve public health sur-
veillance for communica-
ble and chronic illnesses.
EHRs facilitate clinical alerts
informed by public health
goals that guide primary
care physicians in real time
in their diagnosis and treat-
ment of patients.
As health departments
reassess their public health
agendas, the use of EHRs to
facilitate this agenda in pri-
mary care settings should
be considered. PCPs and
EHR vendors, in turn, will
need to configure their EHR
systems and practice work-
flows to align with public
health priorities as these
agendas include increased
involvement of primary
care providers in addressing
public health concerns. (Am

ELECTRONIC HEALTH RECORDS
(EHRs) have great potential to
serve as a catalyst for more effec-
tive coordination between public
health departments and primary
care providers in maintaining
healthy communities. As promi-
nent health risks to the community
continue their shift from conta-
gious diseases to chronic illnesses,
public health departments are in-
creasingly focused on conditions
such as diabetes and obesity. At
the same time, serious threats
persist from traditional public
health concerns, such as commu-
nicable disease outbreaks.
Primary care providers, and
particularly community health
centers (CHCs), that provide care
for low-income populations are
on the front lines in treating and
containing both communicable
diseases and chronic illnesses that
are more prevalent in these com-
munities. Traditional models of
primary care are also evolving, with
increased focus on community-
based approaches in response to
changing financial incentives and
formal recognition programs, such
as the Patient-Centered Medical
Home certification offered by the
National Committee for Quality
Assurance and the Joint Commis-
sion.1,2 Use of these models is
facilitated by the parallel increase
in adoption of EHRs.
Federal incentive programs
have been a proponent of EHR
implementation and “meaningful
use” of EHRs among primary
care providers, with targeted
funding to support their adoption
among CHCs.3 The promotion
of health information technology
to improve the public’s health is
1 of 5 focus areas for meaningful
use of EHRs. Finally, 1 of the
3-part aims of the Centers for
Medicare and Medicaid Services
(CMMS) is the improvement of
population health—a goal that
will only be met through im-
proved coordination of primary
care and public health.4,5
In 2003, the potential for ad-
dressing community health needs
with the aid of EHR data exchange
initiated a partnership between
The New York City Department
of Health and Mental Hygiene
(NYC DOHMH) and The Institute
for Family Health. Together, these
organizations have developed,
tested, implemented, and moni-
tored the use of an EHR in meet-
ing public health and primary care
goals. NYC DOHMH is one of
the world’s largest public health
agencies, operating programs in
disease control, environmental
health, epidemiology, health care
access, health promotion and
disease prevention, and mental
hygiene. It also makes public
health-enabled EHRs available to
over 2500 primary care providers
throughout New York City as part
of its Primary Care Information
Project (PCIP).
The Institute for Family Health
is a nonprofit organization that
provides care to more than 80 000
patients in 26 federally qualified
health center sites in New York
City and New York State’s Mid-
Hudson Valley. The Institute’s
goal in establishing an EHR sys-
tem was not only to enhance the
quality of patient care in its own
practices, but also to improve the
health of the communities it
serves. Recognizing that the 2
organizations had parallel mis-
sions to maintain healthy com-
munities, the Institute and NYC
DOHMH partnered in EHR data
exchange initiatives to meet the
shared goals of improving the
surveillance and management
of both communicable disease
and chronic disease. Projects
addressing these goals are de-
scribed below.
IMPROVE SURVEILLANCE
AND MANAGEMENT OF
COMMUNICABLE DISEASE
Syndromic surveillance, the
practice of monitoring encounters
for symptoms that may represent
infectious diseases and other
conditions of public health con-
cern, can be facilitated by EHRs
through automated data report-
ing to public health departments.
The Institute for Family Health
partnered with NYC DOHMH to
become one of the first ambula-
tory settings to participate in syn-
dromic surveillance.6 Routinely
collected chief complaint infor-
mation along with important de-
mographic data from Institute
patients are de-identified and
transmitted to NYC DOHMH
daily through a secure encrypted
data transfer mechanism. Respi-
ratory illness, fever, diarrhea,
and vomiting are the key symp-
toms monitored, with analysis to
determine when the incidence
of these syndromes exceeds ex-
pected thresholds.
Figures 1 and 2 present the
percentage of patient visits on

a daily and rolling weekly basis in
which influenza-like illness (ILI)
was the documented reason for
visit at all of the Institute’s care
sites in New York City and the
Mid-Hudson Valley (Upstate), re-
spectively, during the H1N1 epi-
demic. These data illustrate that
the peak in ILI visits at Upstate
sites lagged the peak experienced
in New York City sites by 5months,
which guided the Institute to
redistribute immunization re-
sources well after the New York
City peak. The ability to conduct
this type of disease monitoring in
real time has the potential to in-
form primary care providers and
public health departments of
shifting needs during outbreaks.
As increasing numbers of health
care providers implement public
health---enabled EHRs, public
health departments have the
potential to receive syndromic
surveillance data that present
a more comprehensive profile of
the population.
Like many public health de-
partments, NYC DOHMH moni-
tors the incidence of disease
through registries and required
reporting of notifiable conditions,
such as tuberculosis, by health
care providers. Despite legal man-
dates in most states, reporting
rates for these conditions are
not optimal.7,8 The Institute facil-
itated public health reporting by
creating alerts within its EHR that
remind providers at the point of
care that a particular diagnosis is
reportable and provide a link to
the reporting form. Patient demo-
graphics are automatically popu-
lated in the form to minimize
providers’ time and effort in sub-
mitting reports.
Institute data on immunization
and lead screening, which must
be submitted to the city’s public
health registries, are automatically
uploaded from the Institute’s EHR
system to NYC DOHMH, elimi-
nating the need for providers or
staff to submit reports. Primary
care providers can use registry
data to look up immunization his-
tories for patients in their prac-
tices, potentially reducing both
gaps and duplication in immuni-
zation schedules.
Findings from epidemiological
investigation by public health
agencies can inform primary care

practices. This information trig-
gers message distribution through
channels such as the Health Alert
Network in which nearly all large
public health entities participate,
and that may be delivered to the
point of care through EHRs.9,10
The Institute and NYC DOHMH
have tested and implemented
point-of-care public health alerts
for a variety of conditions. For
example, New York City has
issued messages about West Nile
Virus detection through its Health
Alert Network, which Institute
staff programmed as alerts for
their primary care providers,
prompting them to consider this
condition for patients presenting
with fever and headache. In an-
other example, a NYC DOHMH
alert about increased cases of
Legionella in a Bronx neighbor-
hood prompted the Institute to
create an alert to local providers
to consider this condition in pa-
tients with respiratory symptoms.
An order set attached to the
alert facilitated urine antigen
testing that would otherwise have
been unlikely. Such alerts can
prompt primary care providers to
take timely action to appropri-
ately treat patients for emerging
conditions.
Primary care providers can also
be encouraged to take an active
role in disease surveillance efforts.
During a measles outbreak, Insti-
tute providers treating patients
with rash and fever responded
to programmed prompts and col-
lected specimens requested by
NYC DOHMH at the time patients
presented to the clinic. At the
onset of the H1N1 epidemic in
2009, clinical alerts requested
that providers at Institute sites
collect viral specimens for a pilot
surveillance project to determine
the viral etiologies to respiratory
illness in the community.11 Be-
cause of the success of this alert,
the Institute has continued to
provide community level samples
for detecting ILI.
IMPROVE SURVEILLANCE
AND MANAGEMENT OF
CHRONIC DISEASE
Public health departments will
need new tools and partners to
address the growing epidemic of
chronic disease. The functionality
of EHRs can be expanded to em-
power CHCs and other clinicians
to provide better preventive and
acute care through clinical deci-
sion supports.12,13 Still, primary
care providers are challenged to
incorporate dozens of care guide-
lines into practice. The finite re-
sources available across the health
care system make it critically im-
portant to have a public health
agenda that prioritizes services
that have the greatest impact on
health.1,14,15
Recognizing this need, NYC
DOHMH launched the Take Care
New York (TCNY) initiative in
2004.16 TCNY set an ambitious
agenda to prioritize actions to
help New York City improve
health in 10 key areas, each of
which causes significant illness
and death but is amenable to
intervention. NYC DOHMH
established population-level tar-
gets for each of these priority
areas, which include 10 goals for
all New Yorkers:
1. Have a regular doctor or other
health care provider.
2. Be tobacco-free.
3. Keep your heart healthy.
4. Know your HIV status.
5. Get help for depression.
6. Live free of alcohol and drugs.
7. Get checked for cancer.
8. Get the immunizations that
you need.
9. Make your home safe and
healthy.
10. Have a healthy baby.
To integrate the TCNY agenda
into its primary care efforts, the
Institute collaborated with NYC
DOHMH in developing a model
clinical-decision support system
at its practice sites that is orga-
nized around these goals. Health
department and Institute staff
reviewed each goal in the context
of medical evidence and practice
guidelines. A logic model was
created for each goal that incor-
porated available EHR data
and workflows, and also assessed
feasibility and acceptability in
practice. More than 40 alerts
addressing TCNY goals are cur-
rently programmed into the Insti-
tute’s EHR. Mindful of issues such
as “alert fatigue,”17 reminders
were engineered to fit into clinical
workflows and incorporated tools
to facilitate adherence, such as
drop-down order sets, documen-
tation screens, links to patient
education materials, and the op-
tion to suppress the alert if the
recommendation was not indi-
cated for the patient.
Health screening recommenda-
tions incorporated into many of
the TCNY alerts often require care
management and follow-up to
improve health outcomes. As part
of its health care quality program,
the Institute has used EHR data
to develop disease registries and
reports that enable outreach
workers and care managers to
identify and contact patients who
are overdue for a test, screening,
or visit, or have a clinical measure
that requires special attention.
Another critical component of the
TCNY partnership is a reporting
system to monitor these measures
at each practice site. A current
report on all patients with docu-
mented HIV test results, corre-
sponding to TCNY Goal 4, is
presented in Figure 3. This exam-
ple is illustrative of the need to
couple automated alerts with
a supportive health-care delivery
system. Rates of HIV testing began
improving markedly in 2011 as
the Institute’s health centers began
to incorporate on-site rapid test-
ing, market related messages to
patients, and redirect electronic
alerts and order sets to nursing
staff to encourage testing prior to
the patient seeing the provider.
Alerts can also guide providers
to public health resources to
which they can refer patients. For
example, the provider alert to
address smoking, TCNY Goal 2,
contains an embedded, prepopu-
lated referral form for the Fax-to-
Quit line operated by the New
York State Department of Health.
Other possibilities include refer-
rals to free mammography and
additional cancer screening pro-
grams operated by publicly
funded or other programs. This
functionality is particularly perti-
nent to CHCs that serve patients
whose lack of insurance often
creates barriers to health services.
Public health programs should
consider partnering with primary
care providers to use EHRs to
inform them of these types of
community programs at the point
of care.
EHR data can be used to iden-
tify primary care patients at risk
for developing certain chronic
diseases or the sequelae of existing
chronic conditions. Research has
demonstrated that the data typi-
cally stored in EHRs can be used
to identify patients at high risk for
certain diseases and that patient
knowledge of increased risk of
disease may motivate preventive
behavior such as obtaining cancer
screenings or vaccinations.18---20
The Institute has employed clini-
cal data in the EHR to identify and
reach out to patients at increased
risk for disease, with initial pro-
jects focused on colon cancer
screening and diabetes.

Another project uses patients’
demographic data to screen
for Hepatitis B. Screening for
Hepatitis B is not recommended
for the general population; how-
ever, screening is indicated for
immigrants from certain countries
where prevalence is high.21,22 Us-
ing data on patients’ country of
origin, which is part of an organi-
zational initiative to collect patient
data at the granular level, the In-
stitute implemented an alert for
Hepatitis B screening that prompts
providers to order appropriate
testing if the patient is from a
country in which Hepatitis B is
endemic but has not been tested
or diagnosed with this condition.
In the first 5 months after imple-
mentation, the alert “fired” 32 515
times and resulted in the ordering
of 785 Hepatitis B surface anti-
gen tests, with 10 previously
unknown cases of Hepatitis B
identified. Early identification of
chronic infectious diseases in pri-
mary care practices can prevent
adverse outcomes like cirrhosis
and liver cancer.
Racial and ethnic disparities in
health remain a persistent public
health problem. Minimal progress
in this area has been attributed,
in part, to a lack of standardized
demographic data in health care
settings that can identify gaps and
point toward best practices for
eliminating disparities.23---26 Re-
cent federal health care reform
and health information technology
legislation call for health care
providers to collect data on pa-
tients’ race, ethnicity, and lan-
guage as part of health system
change, and lays the foundation
for identifying and addressing
health disparities throughout the
health care system.3,27 EHRs can
become powerful tools in these
efforts when they enable health
quality data to be monitored via
patient demographics at the gran-
ular level.
The Institute has documented
patients’ race, ethnicity, and
preferred language for health
care in its EHR system since its
implementation in 2002, with a
recent expansion of demographic
data collection based on recom-
mendations from The Institute of
Medicine.28 These data enable
the Institute to monitor care pro-
cesses and outcomes for patients
in particular racial and ethnic
groups. Progress reports on
TCNY measures are run by
patient race and ethnicity, as
are disease registries and other
clinical reports. Disparities iden-
tified in the HbA1c levels of
Institute patients with diabetes
spurred the development of an
enhanced diabetes-care model
that incorporates outreach and
care management for patients
with clinical indicators outside of
the recommended range, who are
more likely to be of minority race
or ethnicity. Documenting granu-
lar health data is the first step in
identifying gaps in care for which
both front line providers and
public health agencies can then
marshal resources to identify
individuals and groups experi-
encing barriers to high-quality
primary care and to target public
health education campaigns.
REVIEW
Multiple sources of health data
can inform the priorities and actions
of public health departments, pri-
mary care providers, individuals,
and communities, when appropri-
ately analyzed and coordinated.
EHRs can form the hub of infor-
mation exchange as primary care
providers document illnesses that
can be uploaded to public health
departments to monitor disease
and inform point-of-care decisions
about treatment through provision
of relevant public health informa-
tion. Public health departments
can use aggregated EHR data,
along with other sources of data,
to prioritize community interven-
tions and public health messages,
as well as recommendations for
primary care screenings and
treatment. Individuals and com-
munities make daily decisions
about their health and lifestyles
that are reported to their primary
care providers and to public
health departments through
community surveys and assess-
ments. EHRs can help public
health departments and primary
care providers efficiently coordi-
nate their priorities to ensure that
patients and communities receive
consistent, high-impact health
messages. Data from one point
on the hub can inform action on
another point, forming a commu-
nity health information ecosys-
tem that fosters coordination
of data and health promotion
activities. Figure 4 diagrams the
potential flow of information be-
tween stakeholders.
Although the partners in the
initiatives described herein were
successful in integrating public
health and primary care function-
ality, there are currently several
challenges to expanding these col-
laborations more broadly. First,

adoption of EHRs among primary
care providers is growing yet lim-
ited. Roughly 25% of office-based
physicians in the United States
have a basic EHR system and
another 10% have a fully func-
tional EHR system.29 Furthermore,
there are many EHR systems in
existence today, and this variability
can make it difficult for public
health agencies to engage with
multiple primary care partners and
ensure that key communities are
represented in health partnerships.
Standards for the coding and
transmission of public health data
by EHRs are in development, but
many such standards have yet to
be developed and others have not
been broadly adopted by the EHR
vendor community and by public
health departments. Limited re-
sources constrain the ability of
public health agencies and primary
care providers to collaborate and
innovate.
CONCLUSIONS
Public health departments
and primary care providers must
integrate their efforts in the de-
velopment of electronic health re-
cords if the United States is going
to successfully move from a health
care system that is based on vol-
ume of services to that which is
focused on maintaining healthy
communities. Primary care pro-
viders, as “deputized public health
officers,” have the ability to act as
the eyes of the health department
in the community. They are made
more efficient and effective in this
role when supported by public
health---enabled electronic health
records.
Primary care providers, particu-
larly CHCs, rely on public health
departments to provide the ex-
pert guidance and situational
awareness that facilitates effective
health care delivery. EHRs provide
a mechanism for health depart-
ments to deliver such guidance in
real time, as providers make care
decisions. As public health depart-
ments develop new guidelines and
priorities for improving population
health, it will be important to con-
sider how they can be facilitated
by EHRs in primary care settings.
Primary care providers and EHR
vendors, in turn, will need to con-
figure their EHR systems to align
with public health priorities. In this
time of rapid health information
technology advancement and
health care realignment, it is critical
that public health departments
and primary care providers jointly
plan how to harness the power of
EHRs and achieve the benefits of
integration. j

Strengthening Public Health and Primary CareCollaboration Th.docx

  • 1. Strengthening Public Health and Primary Care Collaboration Through Electronic Health Records Electronic health records (EHRs) have great potential to serve as a catalyst for more effective coordina- tion between public health departments and primary care providers (PCP) in maintaining healthy com- munities. As a system for docu- menting patient health data, EHRs can be harnessed to improve public health sur- veillance for communica- ble and chronic illnesses.
  • 2. EHRs facilitate clinical alerts informed by public health goals that guide primary care physicians in real time in their diagnosis and treat- ment of patients. As health departments reassess their public health agendas, the use of EHRs to facilitate this agenda in pri- mary care settings should be considered. PCPs and EHR vendors, in turn, will need to configure their EHR systems and practice work- flows to align with public health priorities as these agendas include increased
  • 3. involvement of primary care providers in addressing public health concerns. (Am J Public Health. 2012;102: e13–e18. doi:10.2105/AJPH. 2012.301000) Neil Calman, MD, Diane Hauser, MPA, Joseph Lurio, MD, Winfred Y. Wu, MD, MPH, and Michelle Pichardo, MPH ELECTRONIC HEALTH RECORDS (EHRs) have great potential to serve as a catalyst for more effec- tive coordination between public health departments and primary care providers in maintaining healthy communities. As promi- nent health risks to the community continue their shift from conta- gious diseases to chronic illnesses, public health departments are in- creasingly focused on conditions such as diabetes and obesity. At the same time, serious threats persist from traditional public health concerns, such as commu- nicable disease outbreaks. Primary care providers, and
  • 4. particularly community health centers (CHCs), that provide care for low-income populations are on the front lines in treating and containing both communicable diseases and chronic illnesses that are more prevalent in these com- munities. Traditional models of primary care are also evolving, with increased focus on community- based approaches in response to changing financial incentives and formal recognition programs, such as the Patient-Centered Medical Home certification offered by the National Committee for Quality Assurance and the Joint Commis- sion.1,2 Use of these models is facilitated by the parallel increase in adoption of EHRs. Federal incentive programs have been a proponent of EHR implementation and “meaningful use” of EHRs among primary care providers, with targeted funding to support their adoption among CHCs.3 The promotion of health information technology to improve the public’s health is 1 of 5 focus areas for meaningful use of EHRs. Finally, 1 of the 3-part aims of the Centers for Medicare and Medicaid Services (CMMS) is the improvement of
  • 5. population health—a goal that will only be met through im- proved coordination of primary care and public health.4,5 In 2003, the potential for ad- dressing community health needs with the aid of EHR data exchange initiated a partnership between The New York City Department of Health and Mental Hygiene (NYC DOHMH) and The Institute for Family Health. Together, these organizations have developed, tested, implemented, and moni- tored the use of an EHR in meet- ing public health and primary care goals. NYC DOHMH is one of the world’s largest public health agencies, operating programs in disease control, environmental health, epidemiology, health care access, health promotion and disease prevention, and mental hygiene. It also makes public health-enabled EHRs available to over 2500 primary care providers throughout New York City as part of its Primary Care Information Project (PCIP). The Institute for Family Health is a nonprofit organization that provides care to more than 80 000 patients in 26 federally qualified health center sites in New York
  • 6. City and New York State’s Mid- Hudson Valley. The Institute’s goal in establishing an EHR sys- tem was not only to enhance the quality of patient care in its own practices, but also to improve the health of the communities it serves. Recognizing that the 2 organizations had parallel mis- sions to maintain healthy com- munities, the Institute and NYC DOHMH partnered in EHR data exchange initiatives to meet the shared goals of improving the surveillance and management of both communicable disease and chronic disease. Projects addressing these goals are de- scribed below. IMPROVE SURVEILLANCE AND MANAGEMENT OF COMMUNICABLE DISEASE Syndromic surveillance, the practice of monitoring encounters for symptoms that may represent infectious diseases and other conditions of public health con- cern, can be facilitated by EHRs through automated data report- ing to public health departments. The Institute for Family Health partnered with NYC DOHMH to become one of the first ambula-
  • 7. tory settings to participate in syn- dromic surveillance.6 Routinely collected chief complaint infor- mation along with important de- mographic data from Institute patients are de-identified and transmitted to NYC DOHMH daily through a secure encrypted data transfer mechanism. Respi- ratory illness, fever, diarrhea, and vomiting are the key symp- toms monitored, with analysis to determine when the incidence of these syndromes exceeds ex- pected thresholds. Figures 1 and 2 present the percentage of patient visits on STRENGTHENING COLLABORATION THROUGH ELECTRONIC HEALTH RECORDS November 2012, Vol 102, No. 11 | American Journal of Public Health Calman et al. | Peer Reviewed | Strengthening Collaboration | e13 a daily and rolling weekly basis in which influenza-like illness (ILI) was the documented reason for visit at all of the Institute’s care sites in New York City and the Mid-Hudson Valley (Upstate), re- spectively, during the H1N1 epi-
  • 8. demic. These data illustrate that the peak in ILI visits at Upstate sites lagged the peak experienced in New York City sites by 5months, which guided the Institute to redistribute immunization re- sources well after the New York City peak. The ability to conduct this type of disease monitoring in real time has the potential to in- form primary care providers and public health departments of shifting needs during outbreaks. As increasing numbers of health care providers implement public health---enabled EHRs, public health departments have the potential to receive syndromic surveillance data that present a more comprehensive profile of the population. Like many public health de- partments, NYC DOHMH moni- tors the incidence of disease through registries and required reporting of notifiable conditions, such as tuberculosis, by health care providers. Despite legal man- dates in most states, reporting rates for these conditions are not optimal.7,8 The Institute facil- itated public health reporting by creating alerts within its EHR that
  • 9. remind providers at the point of care that a particular diagnosis is reportable and provide a link to the reporting form. Patient demo- graphics are automatically popu- lated in the form to minimize providers’ time and effort in sub- mitting reports. Institute data on immunization and lead screening, which must be submitted to the city’s public health registries, are automatically uploaded from the Institute’s EHR system to NYC DOHMH, elimi- nating the need for providers or staff to submit reports. Primary care providers can use registry data to look up immunization his- tories for patients in their prac- tices, potentially reducing both gaps and duplication in immuni- zation schedules. Findings from epidemiological investigation by public health agencies can inform primary care FIGURE 1—Percentage of patient visits at New York City sites for influenza-like illness (ILI): Institute for Family Health, June 8–December 4, 2009.

American Journal of Public Health | November 2012, Vol 102, No. 11 practices. This information trig- gers message distribution through channels such as the Health Alert Network in which nearly all large public health entities participate, and that may be delivered to the point of care through EHRs.9,10 The Institute and NYC DOHMH have tested and implemented point-of-care public health alerts for a variety of conditions. For example, New York City has issued messages about West Nile Virus detection through its Health Alert Network, which Institute staff programmed as alerts for their primary care providers, prompting them to consider this condition for patients presenting with fever and headache. In an- other example, a NYC DOHMH alert about increased cases of Legionella in a Bronx neighbor-
  • 11. hood prompted the Institute to create an alert to local providers to consider this condition in pa- tients with respiratory symptoms. An order set attached to the alert facilitated urine antigen testing that would otherwise have been unlikely. Such alerts can prompt primary care providers to take timely action to appropri- ately treat patients for emerging conditions. Primary care providers can also be encouraged to take an active role in disease surveillance efforts. During a measles outbreak, Insti- tute providers treating patients with rash and fever responded to programmed prompts and col- lected specimens requested by NYC DOHMH at the time patients presented to the clinic. At the onset of the H1N1 epidemic in 2009, clinical alerts requested that providers at Institute sites collect viral specimens for a pilot surveillance project to determine the viral etiologies to respiratory illness in the community.11 Be- cause of the success of this alert, the Institute has continued to provide community level samples for detecting ILI.
  • 12. IMPROVE SURVEILLANCE AND MANAGEMENT OF CHRONIC DISEASE Public health departments will need new tools and partners to address the growing epidemic of chronic disease. The functionality of EHRs can be expanded to em- power CHCs and other clinicians to provide better preventive and acute care through clinical deci- sion supports.12,13 Still, primary care providers are challenged to incorporate dozens of care guide- lines into practice. The finite re- sources available across the health care system make it critically im- portant to have a public health agenda that prioritizes services that have the greatest impact on health.1,14,15 Recognizing this need, NYC DOHMH launched the Take Care New York (TCNY) initiative in 2004.16 TCNY set an ambitious agenda to prioritize actions to help New York City improve health in 10 key areas, each of which causes significant illness and death but is amenable to intervention. NYC DOHMH established population-level tar- gets for each of these priority areas, which include 10 goals for
  • 13. all New Yorkers: 1. Have a regular doctor or other health care provider. 2. Be tobacco-free. 3. Keep your heart healthy. 4. Know your HIV status. 5. Get help for depression. 6. Live free of alcohol and drugs. 7. Get checked for cancer. 8. Get the immunizations that you need. 9. Make your home safe and healthy. 10. Have a healthy baby. To integrate the TCNY agenda into its primary care efforts, the Institute collaborated with NYC DOHMH in developing a model clinical-decision support system at its practice sites that is orga- nized around these goals. Health department and Institute staff reviewed each goal in the context of medical evidence and practice guidelines. A logic model was created for each goal that incor- porated available EHR data and workflows, and also assessed feasibility and acceptability in practice. More than 40 alerts addressing TCNY goals are cur-
  • 14. rently programmed into the Insti- tute’s EHR. Mindful of issues such as “alert fatigue,”17 reminders were engineered to fit into clinical workflows and incorporated tools to facilitate adherence, such as drop-down order sets, documen- tation screens, links to patient education materials, and the op- tion to suppress the alert if the recommendation was not indi- cated for the patient. Health screening recommenda- tions incorporated into many of the TCNY alerts often require care management and follow-up to improve health outcomes. As part of its health care quality program, the Institute has used EHR data to develop disease registries and reports that enable outreach workers and care managers to identify and contact patients who are overdue for a test, screening, or visit, or have a clinical measure that requires special attention. Another critical component of the TCNY partnership is a reporting system to monitor these measures at each practice site. A current report on all patients with docu- mented HIV test results, corre- sponding to TCNY Goal 4, is presented in Figure 3. This exam- ple is illustrative of the need to
  • 15. couple automated alerts with a supportive health-care delivery system. Rates of HIV testing began improving markedly in 2011 as the Institute’s health centers began to incorporate on-site rapid test- ing, market related messages to patients, and redirect electronic alerts and order sets to nursing staff to encourage testing prior to the patient seeing the provider. Alerts can also guide providers to public health resources to which they can refer patients. For example, the provider alert to address smoking, TCNY Goal 2, contains an embedded, prepopu- lated referral form for the Fax-to- Quit line operated by the New York State Department of Health. Other possibilities include refer- rals to free mammography and additional cancer screening pro- grams operated by publicly funded or other programs. This functionality is particularly perti- nent to CHCs that serve patients whose lack of insurance often creates barriers to health services. Public health programs should consider partnering with primary care providers to use EHRs to inform them of these types of community programs at the point
  • 16. of care. EHR data can be used to iden- tify primary care patients at risk for developing certain chronic diseases or the sequelae of existing chronic conditions. Research has demonstrated that the data typi- cally stored in EHRs can be used to identify patients at high risk for certain diseases and that patient knowledge of increased risk of disease may motivate preventive behavior such as obtaining cancer screenings or vaccinations.18---20 The Institute has employed clini- cal data in the EHR to identify and reach out to patients at increased risk for disease, with initial pro- jects focused on colon cancer screening and diabetes. STRENGTHENING COLLABORATION THROUGH ELECTRONIC HEALTH RECORDS November 2012, Vol 102, No. 11 | American Journal of Public Health Calman et al. | Peer Reviewed | Strengthening Collaboration | e15 Another project uses patients’ demographic data to screen for Hepatitis B. Screening for Hepatitis B is not recommended
  • 17. for the general population; how- ever, screening is indicated for immigrants from certain countries where prevalence is high.21,22 Us- ing data on patients’ country of origin, which is part of an organi- zational initiative to collect patient data at the granular level, the In- stitute implemented an alert for Hepatitis B screening that prompts providers to order appropriate testing if the patient is from a country in which Hepatitis B is endemic but has not been tested or diagnosed with this condition. In the first 5 months after imple- mentation, the alert “fired” 32 515 times and resulted in the ordering of 785 Hepatitis B surface anti- gen tests, with 10 previously unknown cases of Hepatitis B identified. Early identification of chronic infectious diseases in pri- mary care practices can prevent adverse outcomes like cirrhosis and liver cancer. Racial and ethnic disparities in health remain a persistent public health problem. Minimal progress in this area has been attributed, in part, to a lack of standardized demographic data in health care settings that can identify gaps and point toward best practices for eliminating disparities.23---26 Re-
  • 18. cent federal health care reform and health information technology legislation call for health care providers to collect data on pa- tients’ race, ethnicity, and lan- guage as part of health system change, and lays the foundation for identifying and addressing health disparities throughout the health care system.3,27 EHRs can become powerful tools in these efforts when they enable health quality data to be monitored via patient demographics at the gran- ular level. The Institute has documented patients’ race, ethnicity, and preferred language for health care in its EHR system since its implementation in 2002, with a recent expansion of demographic data collection based on recom- mendations from The Institute of Medicine.28 These data enable the Institute to monitor care pro- cesses and outcomes for patients in particular racial and ethnic groups. Progress reports on TCNY measures are run by patient race and ethnicity, as are disease registries and other clinical reports. Disparities iden- tified in the HbA1c levels of Institute patients with diabetes
  • 19. spurred the development of an enhanced diabetes-care model that incorporates outreach and care management for patients with clinical indicators outside of the recommended range, who are more likely to be of minority race or ethnicity. Documenting granu- lar health data is the first step in identifying gaps in care for which both front line providers and public health agencies can then marshal resources to identify individuals and groups experi- encing barriers to high-quality primary care and to target public health education campaigns. REVIEW Multiple sources of health data can inform the priorities and actions of public health departments, pri- mary care providers, individuals, and communities, when appropri- ately analyzed and coordinated. EHRs can form the hub of infor- mation exchange as primary care providers document illnesses that can be uploaded to public health departments to monitor disease and inform point-of-care decisions about treatment through provision of relevant public health informa- tion. Public health departments can use aggregated EHR data,
  • 20. along with other sources of data, to prioritize community interven- tions and public health messages, as well as recommendations for primary care screenings and treatment. Individuals and com- munities make daily decisions about their health and lifestyles that are reported to their primary care providers and to public health departments through community surveys and assess- ments. EHRs can help public health departments and primary care providers efficiently coordi- nate their priorities to ensure that patients and communities receive consistent, high-impact health messages. Data from one point on the hub can inform action on another point, forming a commu- nity health information ecosys- tem that fosters coordination

  • 25. adoption of EHRs among primary care providers is growing yet lim- ited. Roughly 25% of office-based physicians in the United States have a basic EHR system and another 10% have a fully func- tional EHR system.29 Furthermore, there are many EHR systems in existence today, and this variability can make it difficult for public health agencies to engage with multiple primary care partners and ensure that key communities are represented in health partnerships. Standards for the coding and transmission of public health data by EHRs are in development, but many such standards have yet to be developed and others have not been broadly adopted by the EHR vendor community and by public health departments. Limited re- sources constrain the ability of public health agencies and primary care providers to collaborate and innovate. CONCLUSIONS Public health departments and primary care providers must integrate their efforts in the de- velopment of electronic health re- cords if the United States is going to successfully move from a health
  • 26. care system that is based on vol- ume of services to that which is focused on maintaining healthy communities. Primary care pro- viders, as “deputized public health officers,” have the ability to act as the eyes of the health department in the community. They are made more efficient and effective in this role when supported by public health---enabled electronic health records. Primary care providers, particu- larly CHCs, rely on public health departments to provide the ex- pert guidance and situational awareness that facilitates effective health care delivery. EHRs provide a mechanism for health depart- ments to deliver such guidance in real time, as providers make care decisions. As public health depart- ments develop new guidelines and priorities for improving population health, it will be important to con- sider how they can be facilitated by EHRs in primary care settings. Primary care providers and EHR vendors, in turn, will need to con- figure their EHR systems to align with public health priorities. In this time of rapid health information technology advancement and health care realignment, it is critical
  • 27. that public health departments and primary care providers jointly plan how to harness the power of EHRs and achieve the benefits of integration. j About the Authors Neil Calman, Diane Hauser, Joseph Lurio, and Michelle Pichardo are with The Institute for Family Health, New York, NY.
