Effects of an Electronic Health Record Choice Architecture Intervention on Inpatient Hemoglobin A1c Testing Rates and Patient Outcomes
Authors' conclusion
This simple, scalable electronic health record intervention was significantly associated with increased rates of inpatient HbA1c testing across multiple hospitals and admitting services, as well as reduced readmissions.
Study context
- Population
- Adult inpatients with diabetes in a health system
- Participants
- 5,598 vs 5,847
- Exposure
- Postintervention vs preintervention
- Postinterventionn = 5,598
- Preinterventionn = 5,847reference
- Outcome
- Inpatient HbA1c testing rate
Methodological detailspreintervention vs postintervention
- Preintervention vs postintervention
Main finding
As reported in the abstract
Hemoglobin A1c (HbA1c) testing rates improved immediately and remained significantly elevated over time (preintervention to postintervention)
64.7% to 78.8%
P < .001
Observational data: associations, not effects.
Further findings
30-day readmission
- Decreased 30-day readmission rates with the intervention, adjusted for covariates (OR)
- 0.88, 95%CI 0.78-0.998; P = .046
HbA1c testing by admitting specialty
- Improvements in HbA1c testing across multiple admitting specialties, incl. internal medicine, surgery, intensive care and psychiatry
Endocrine consultation, LOS, mortality
- No changes in inpatient endocrine consultation rates, LOS or mortality
