BACKGROUND: During pandemics of novel influenza and outbreaks of emerging
infections, surge in health-care demand can exceed capacity to provide normal
standards of care. In such exceptional circumstances, triage tools may aid
decisions in identifying people who are most likely to benefit from higher levels
of care. Rapid research during the early phase of an outbreak should allow
refinement and validation of triage tools so that in the event of surge a valid
tool is available. The overarching study aim is to conduct a prospective near
real-time analysis of structured clinical assessments of influenza-like illness
(ILI) using primary care electronic health records (EHRs) during a pandemic. This
abstract summarises the preparatory work, infrastructure development, user
testing and proof-of-concept study. OBJECTIVES: (1) In preparation for conducting
rapid research in the early phase of a future outbreak, to develop processes that
allow near real-time analysis of general practitioner (GP) assessments of people
presenting with ILI, management decisions and patient outcomes. (2) As proof of
concept: conduct a pilot study evaluating the performance of the triage tools
'Community Assessment Tools' and 'Pandemic Medical Early Warning Score' to
predict hospital admission and death in patients presenting with ILI to GPs
during inter-pandemic winter seasons. DESIGN: Prospective near real-time analysis
of structured clinical assessments and anonymised linkage to data from EHRs. User
experience was evaluated by semistructured interviews with participating GPs.
SETTING: Thirty GPs in England, Wales and Scotland, participating in the Clinical
Practice Research Datalink. PARTICIPANTS: All people presenting with ILI.
INTERVENTIONS: None. MAIN OUTCOME MEASURES: Study outcome is proof of concept
through demonstration of data capture and near real-time analysis. Primary
patient outcomes were hospital admission within 24 hours and death (all causes)
within 30 days of GP assessment. Secondary patient outcomes included GP decision
to prescribe antibiotics and/or influenza-specific antiviral drugs and/or refer
to hospital - if admitted, the need for higher levels of care and length of
hospital stay. DATA SOURCES: Linked anonymised data from a web-based structured
clinical assessment and primary care EHRs. RESULTS: In the 24 months to April
2015, data from 704 adult and 159 child consultations by 30 GPs were captured.
GPs referred 11 (1.6%) adults and six (3.8%) children to hospital. There were 13
(1.8%) deaths of adults and two (1.3%) of children. There were too few outcome
events to draw any conclusions regarding the performance of the triage tools. GP
interviews showed that although there were some difficulties with installation,
the web-based data collection tool was quick and easy to use. Some GPs felt that
a minimal monetary incentive would promote participation. CONCLUSIONS: We have
developed processes that allow capture and near real-time automated analysis of
GP's clinical assessments and management decisions of people presenting with ILI.
FUTURE WORK: We will develop processes to include other EHR systems, attempt
linkage to data on influenza surveillance and maintain processes in readiness for
a future outbreak. STUDY REGISTRATION: This study is registered as ISRCTN87130712
and UK Clinical Research Network 12827. FUNDING: The National Institute for
Health Research Health Technology Assessment programme. MGS is supported by the
UK NIHR Health Protection Research Unit in Emerging and Zoonotic Infections.
