24. Prescriber Indicators: Factor Structure
Factor 1: # of patients
# opioid prescriptions
# benzodiazepine prescriptions
# prescriptions written daily
# opioid prescriptions written daily
Factor 2: Average daily MME
% of patients with average daily MME > 100
Factor 3: # stimulant prescriptions
(-) % of prescriptions paid for by cash
Factor 4: % of patients meeting MPE threshold
Average distance travelled by patients
25. Conclusions
⢠Being in the top 1% of Maine prescribers on number of
patients issued a CS prescription, prescriptions per day,
opioid prescriptions per day, or average daily dosage of
opioids prescribed (MMEs) is associated with being
subject to a Medical Board action for inappropriate
prescribing and with prescription restrictions
⢠Being in the top 1% for MMEs per day is associated
with being subject to a severe action by the Board
⢠Being in the top 2% of prescribers for average distance
traveled by their patients is also associated with being
subject to a severe action by the Board
26. Study Limitations
⢠Findings may not be generalizable to other states: rural
state; relatively small number of Board actions taken
â We have validation studies in process with Ohio and
Washington
⢠Board actions reactive rather than proactive
⢠Unknown lead time before Board takes action
â We have follow-up study of Board actions to address this
question; also effects of Board actions and Board decision-
making process
27. Next Steps
⢠Examine Ringwalt measures of co-prescribing of
benzodiazepines and > 100 MME opioids, and
overlapping CS prescriptions
⢠Explore measure interactions (e.g., top 1% of
prescribers on volume and top X% on risk indicator)
⢠Examine prescribing profiles based on prescriber â
drug networks, in relation to specialty

35. Identifying prescribers who prescribe very high
levels of controlled substances: Partners
⢠Partnership between DMH/DD/SAS, UNC IPRC, and UNC
Department of Surgery to develop algorithms
⢠Partnership with NC Medical Board for possible
investigation of identified prescribers
36. Identifying prescribers who prescribe very high
levels of controlled substances: Methodology
⢠Project goal: Develop and validate algorithms using PDMP (NC
CSRS) data to identify prescribers with unusual prescribing
patterns.
⢠Algorithms evaluated:
⢠Rates of prescriptions for daily dose > 100 MME
⢠High average daily MME*
⢠High total MME per prescription
⢠Prescription rates for opioids, benzodiazepines, stimulants*
⢠Rates of co-prescribed opioids (> 100 MME) and benzodiazepines*
⢠Temporally overlapping prescriptions*
⢠Long travel distance by patient to prescriber or pharmacy
⢠Multiple prescribers for controlled substances
⢠Multiple pharmacies for controlled substances
* Algorithms most closely associated with deaths from overdose
37. Identifying prescribers who prescribe very high
levels of controlled substances: Methodology
⢠NC Medical Board receives lists of prescribers who are in:
⢠Top 1% of those prescribing 100 milligrams of morphine
equivalents (âMMEâ) per patient per day
⢠OR
⢠Falls within the top 1% of those prescribing 100 MMEâs per patient
per day in combination with any benzodiazepine and who are
within the top 1% of all controlled substance prescribers by
volume
38. Identifying prescribers who prescribe very high
levels of controlled substances: Next steps
⢠Identify additional data elements to be added to metrics
to improve sensitivity of metrics and reduce false
positives. Concern is time required for investigations and
impact of investigations on legitimate prescribers.
⢠Work with NCMB Advisory Group (2 Board members and 3
consultants) to develop objective criteria to decide
whether or not to open an investigation
40. Identifying prescribers with more than one
patient with an opioid-related death: Partners
⢠Partnership between NC Division of Mental Health,
Developmental Disabilities and Substance Abuse Services
and NC Injury andViolence Prevention Branch of the
Division of Public Health to develop algorithms
⢠Partnership with NC Medical Board for possible
investigation of identified prescribers
41. Identifying prescribers with more than one
patient with an opioid-related death: Methods
⢠Identified deaths attributed to unintentional or
undetermined controlled substance-related poisoning
usingVital Records Death Certificate file.
⢠Linked to CSRS data to identify those who prescribed the
decedent a controlled substance prescription within 60
days prior to death.
⢠Linked to CSRS andVital Records to determine whether
the prescriber(s) had any other patient deaths due to
substance-related poising during the prior 12 months
⢠Prescribers with two or more controlled-substance related
deaths in the past 12 months referred to NCMB
42. Identifying prescribers with more than one
patient with an opioid-related death: Results
⢠Validation results:
⢠465 opioid overdose-related deaths identified in 2012
⢠651 prescribers prescribed opioids to these patients within 30 days
of their death
⢠Match to prescribers who fall in top 1% of all CS prescribers and
100+ MME prescribers
⢠30-46% of prescribers who fell in top 1% of metrics also had
prescribed an opioid to a patient within 30 days of their death

and Carolinas Healthcare System (CHS).
46. Immediate feedback on high risk patients
through healthcare system prescription
records and PDMP data: Methods
⢠Integration of decision support in to electronic medical
record (EMR) using 5 criteria to trigger an alert.
⢠Existing prescription with >50% prescription duration remaining
⢠2+ visits to ED with on-site administration of controlled substance
⢠3+ controlled substance prescriptions in last 30 days
⢠Positive screen for blood alcohol, cocaine, or marijuana
⢠Previous presentation to ED for overdose
47. Immediate feedback on high risk patients
through healthcare system prescription
records and PDMP data: Results
⢠Two silent phases used to tune alert triggers to have
acceptable number of relevant alerts at point of care.
⢠Alerts generated for 5.9% of prescribing encounters
⢠Majority of prescribing encounters in outpatient setting.
⢠Inpatient discharges and ED/Urgent Care encounters have
disproportionately high rates of opioid and
benzodiazepine prescriptions.
48. Immediate feedback on high risk patients
through healthcare system prescription
records and PDMP data: Next steps
⢠Assess burden on prescribers.
⢠Evaluation of impact on prescribing patterns.
⢠Integration of PDMP data in to EMR and alerts
49. Navigating policy hurdles: Lessons learned
⢠Access to PDMP (CSRS) data: sensitive data requires high
level of security and confidentiality. Striking the balance
between legal protection, legal authority, and clinical
interest.
⢠Investigating prescribers is a big deal, so need to ensure
that metrics identify only prescribers truly warranting
investigation.
⢠Need to balance vigorous regulatory efforts with potential
chilling effect on other prescribers and the right for
adequate pain control for many patients
50. Navigating technical hurdles: Lessons
learned
⢠Storage and processing power requirements are
significant for analysis of large databases.
⢠Extensive cleaning of PDMP (CSRS) data required.
⢠Clear, complete data dictionaries needed for all datasets
to avoid errors due to assumptions on how data are
collected and defined.
51. Importance of the partnerships
⢠Utilization of research, evaluation, and data science skill
sets from an academic institution (UNC), a large
healthcare system (CHS), the NC Division of Public Health,
and the NC Division of Mental Health/Developmental
Disabilities/Substance Abuse Services
⢠Integration by research partners of topic-specific
knowledge and experience from DMH/DD/SAS and NCMB
staff, as well as CHS prescribers
52. Importance of the partnerships, continued
⢠Translation of research into practice through investigative
efforts of NCMB
⢠Because this is a multi-disciplinary, multi-jurisdictional
problem, increased coordination and communication are
essential. NC continues to identify ways in which key
stakeholders can collaborate and share knowledge to
address common problems.

Editor's Notes
This distribution â approximately 80% of total prescriptions accounted for by the top 20% of prescribers, is quite consistent across states.
Note the association between average volume of opioid prescriptions prescribed and average daily dosage of patients.
This graph shows an association between the average distance patients travel to prescribers (aggregated into prescriber deciles based on distance patients travel) and the percentage of the prescribersâ patients who meet the multiple provider episode criteria (MPE: 5 or more prescribers and 5 or more pharmacies in a 3-month period). The association appears to be logarithmic.
For questions or more information.
Algorithms evaluated:
Rates of prescriptions for daily dose > 100 MME
High average daily MME (what the patient takes each day)
High total MME per prescription (whatâs in the bottle â daily dose x days)
Prescription rates for opioids, benzodiazepines, stimulants
Rates of co-prescribed opioids (> 100 MME) and benzodiazepines
Temporally overlapping prescriptions
Long travel distance by patient to prescriber or pharmacy
Multiple prescribers for controlled substances (doctor shopping)
Multiple pharmacies for controlled substances (pharmacy shopping)
Initial screen, then other processes to maximize sensitivity and minimize false positives.
Burden of opening investigations â could damage the career of the prescriber, even if the prescriber is prescribing appropriately.
May need to consider # of prescriptions written by prescriber, since 2 deaths
