Spending more time on electronic health records was associated with greater quality ambulatory care, a study published in JAMA Network Open found.

Perspective from Conrad L Flick, MD

While EHRs have become pivotal in primary care settings, they also have a consistent history of burnout association. Thus, “understanding the associations between EHR time and outcomes could help disentangle the evidence on the association between burnout and quality,” Lisa S. Rotenstein, MD, MBA, an assistant professor at Harvard Medical School, and colleagues wrote.

Data derived from: Rotenstein LS, et al. JAMA Netw Open. 2022;doi:10.1001/jamanetworkopen.2022.37086.

The researchers’ cross-sectional study included 291 primary care physicians with a longitudinal patient panel, 59.8% (n = 174) of whom were women. All served at Brigham and Women’s Hospital or Massachusetts General Hospital.

EHR usage data were collected in 2021.

“By averaging values from each of 12-monthly EHR system data extracts, we calculated physician-level daily means of multiple EHR use metrics,” Rotenstein and colleagues wrote.

Among several EHR metrics examined were:

  • total daily EHR time;
  • daily time spent in clinical reviews;
  • daily time spent composing notes; and
  • daily time spent in the EHR system module — referred to as the in-basket — sending and receiving PCP, staff and system messages.

For outcome variables, the researchers used five adult ambulatory care metrics that are accepted among PCPs and most likely to be influenced by PCPs: HbA1c control in patients with established diabetes, lipid management in patients with established CVD, BP control in patients with established hypertension and screening rates for diabetes and breast cancer.

Rosenstein and colleagues found that PCPs spent a mean of 145.9 daily minutes on the EHR in total, with 26.1 daily minutes on clinical review time and 31 daily minutes in the in-basket. An additional 15 minutes of daily EHR time was associated with:

  • 0.58 percentage point (95% CI, 0.32-0.84) greater HbA1c control;
  • 0.52 percentage point (95% CI, 0.33-0.71) greater hypertension control; and
  • 0.28 percentage point (95% CI, 0.05-0.52) higher breast cancer screening rates.

An additional 15 daily minutes of in-basket time, meanwhile, was linked to:

  • 2.26 percentage point (95% CI, 1.05-3.48) greater HbA1c control;
  • 1.65 percentage point (95% CI, 0.83-2.47) greater hypertension control; and
  • 1.26 percentage point (95% CI, 0.51-2.02) higher breast cancer screenings.

Adjusted analyses performed by Rosenstein and colleagues showed that clinical review time and notes resulted in 1.64 percentage point (95% CI, 0.49-2.78) and 0.64 percentage point (95% CI, 0.21-1.07) greater HbA1c control with an additional 15 minutes of daily EHR use, respectively.

Despite the burnout association, the researchers noted that increased EHR time “may represent a level of thoroughness, attention to detail, or patient and team communication that ultimately enhances certain outcomes.”

Rosenstein and colleagues also highlighted that daily time in the in-basket and on clinical notes had the greatest numerical association with ambulatory outcomes, a notable result since in-basket time is not usually considered in compensation. Instead, it increases the risk for burnout and intentions to reduce clinical hours.

“Our findings suggest that as PCPs and patients have become more comfortable with electronic correspondence, PCPs who spend more time corresponding with their patients and team members about care coordination, test results, and clinical follow-up may be more likely to achieve target clinical outcomes for diabetes and hypertension and to have higher rates of breast cancer screening in their panels,” they wrote.

The researchers acknowledged that the study was limited in that the two medical centers may not be representative of the PCP workforce, and a lack of data on patient-PCP interaction prevented further adjustments.

“It may be useful for future studies to characterize payment models, workflows, and technologies that enable high-quality ambulatory care delivery while minimizing EHR burden,” Rotenstein said in a press release.
