This study, published in Health Affairs, used data captured by the access time stamp functionality of an electronic health record (EHR) to examine physician work effort. The authors used data on physicians’ time allocation patterns captured by over 31 million EHR transactions in the period 2011–14 recorded by 471 primary care physicians, who collectively worked on 765,129 patients EHRs. The results suggest that the physicians logged an average of 3.08 hours on office visits and 3.17 hours on desktop medicine each day. Over time, log records from physicians showed a decline in the time allocated to face-to-face visits, accompanied by an increase in time allocated to desktop medicine.
