Abstract

Objective. This study compares results and illustrates trade-offs between work-sampling and time-and-motion methodologies. Data Sources. Data are from time-and-motion measurements of a sample of medical residents in two large urban hospitals. Study Design. The study contrasts the precision of work-sampling and time-and-motion techniques using dataactually collected using the time-and-motion approach. That data set was used to generate a simulated set of work-sampling data points. Data Collection/Extraction Methods. Trained observers followed residents during their 24-hour day and recorded the start and end time of each activity performed by the resident. The activities were coded and then grouped into ten major categories. Work-sampling data were derived from the raw time-and-motion data for hourly, half-hourly, and quarter-hourly observations. Principal Findings. The actual time spent on different tasks as assessed by the time-and-motion analysis differed from the percent of time projected by work-sampling. The work-sampling results differed by 20 percent or more of the estimated value for eight of the ten activities. As expected, the standard deviation decreases as work-sampling observations become more frequent. Conclusions. Findings indicate that the work-sampling approach, as commonly employed, may notprovide an acceptably precise approximation of the result that would be obtained by time-and-motion observations.
