Adjusted association between EHR use and HbA1c and LDL-C values by primary care team cohesion level

Average change in HbA1c (%) 95% CI Average change in LDL-C (mg/dL) 95% CI
Higher team cohesion: EHR vs. No EHR −0.11*** [−0.12, −0.09] −2.15*** [−2.43, −1.86]
Lower team cohesion: EHR vs. No EHR1 −0.08*** [−0.10, −0.07] −1.42*** [−1.80, −1.03]
Difference in EHR association for higher vs. lower team cohesion2 0.02** [0.01,0.03] 0.73*** [0.41,1.11]

Note: We used linear regression with fixed effects at patient level, adjusted for calendar quarter, calendar year, and dummy variables to control for medical center fixed effects.

1

EHR effect for teams with lower cohesion was calculated by adding the EHR effect estimate by the interaction of EHR and lower team cohesion.

2

The interaction coefficient for EHR and lower cohesion represents the difference in the EHR association on clinical outcome for patients cared for by teams with higher versus lower team cohesion.

EHR = Electronic Health Record, CI = Confidence Interval, LDL-C = Low Density Lipoprotein-Cholesterol, HbA1c= Glycosylated Hemoglobin A Protein.
