title: Systematic review of time studies evaluating physicians in the hospital setting.
abstract: BACKGROUND
  Time studies, first developed in the late 19th century, are now being used to evaluate and improve worker efficiency in the hospital setting. This is the first review of hospital time study literature of which we are aware.
  
  
  OBJECTIVE
  We performed a systematic review of the literature to better understand the available time study literature describing the activities of hospital physicians.
  
  
  METHODS
  We searched MEDLINE, EMBASE, EMBASE Classic, PsycINFO, Cochrane Library, CINAHL, and Web of Science. We also manually reviewed the reference lists of retrieved articles and consulted experts in the field to identify additional articles for review.
  
  
  METHODS
  We selected studies that used time-motion or work-sampling performed via direct observation, included physicians, medical residents, or interns in their study population, and were performed on an inpatient hospital ward.
  
  
  METHODS
  We abstracted data on subject population, study site, collection tools, and percentage of time spent on key categories of activity.
  
  
  RESULTS
  Our search produced 11 time-motion and 2 work-sampling studies that met our criteria. These studies focused primarily on academic hospitals (92%) and the activities of physicians in training (69%). Other results varied widely. A lack of methodological standardization and dissimilar activity categorizations inhibited our efforts to summarize detailed findings across studies. However, we consistently found that activities indirectly related to a patient's care took more of hospital physicians' time than direct interaction with hospitalized patients.
  
  
  CONCLUSIONS
  Time studies, when properly performed, have a great deal to offer in helping us understand and reengineer hospital care.
