14 November 2013, LSHTM
Background
• Electronic Health Record (EHR): ‘longitudinal electronic record
of an individual that contains data from multiple EMRs and
EPRs; shared and interoperable across settings’ (Singleton et
al., 2007, p. 19).
o Used for health, research and policy/planning purposes simultaneously.

• Tensions between wider health information sharing and privacy
protection.
• Wealth of research on patient views, but little large-scale work
on integrated EHRs simultaneously used for different purposes.
Electronic Health Records project
Quantitative component
• Large-scale cross-sectional questionnaire survey with a total of
5,331 participants (85.5% response rate).
• Stratified cluster random sample of patients and members of the
public in an area of West London, UK.
• Recruitment in 8 outpatient waiting areas of a teaching hospital
and the waiting rooms of 8 general practice (GP) surgeries within
the hospital catchment area over a 6-week period from 1 August
2011.
• 2,554 respondents (48%) included in the full analysis sample for
research-related variables.

Multivariable analysis: research user groups
Similar patterns for access by different user groups:
- Individuals who were more likely to say they would allow access to
their identifiable, compared with anonymised data.
-

Older age
Men
Non-white-British
Lower education levels

- People with no academic qualifications compared with higher
degrees more likely to agree with access to their identifiable
information (RR=3.89 for NHS researchers, RR=4.67 for academic
researchers, RR=11.63 for health charities, RR=10.19 for drug
companies, p=0.00 in all cases).
Multivariable analysis: research user groups
- Non-White-British respondents were much more likely to say they
would not allow any access at all than to share their
anonymised data for research.
Consent preferences
• Before use of identifiable records: Around 91% would prefer
to be asked for permission against 9% who would not like to
be asked.
• Before use of records without identifiers: Around 54% would
prefer to be asked for permission against 46% who would not
like to be asked.
Conclusions
• There is support for integrated EHRs, with accompanying
security concerns.
• Preferences for research access to EHRs are nuanced.
• There are clear differences in preferences by ethnic group
and by education level, which need to be understood
further.
• Any database needs to be developed and used sensitively,
taking into account all concerns, not simply those of the
majority group.
