Utilization of physical therapy personnel in one hospital. A work sampling study.

Abstract

The purpose of this study was to illustrate the adaptability and use of work sampling, an industrial engineering technique, as a dependable method for collecting personnel utilization data in the physical therapy department of a general hospital and to demonstrate the concept of work sampling to physical therapy supervisors and personnel unfamiliar with this approach. Over a six-week period, a total of 5,824 observations were made at randomly selected 15-minute intervals during the 40-hour work week. Percentages of total time used in observed activities for all physical therapy personnel were divided as follows: 1) direct care, 20.38 percent; 2) indirect care, 11.18 percent; 3) administration, 2.27 percent; 4) communication, 3.28 percent; 5) clerical, 9.56 percent; 6) personal time, 24.60 percent; and 7) out-of-department, 28.72 percent. Physical therapists were most likely to be involved in personal duties from 8 AM to 9 AM (35%) and from 4 PM to 4:30 PM (41%). They showed greatest productivity from 9 AM to 10 AM (59%) and spent time in out-of-department activities rather consistently throughout the day. A conclusion of this study was that work sampling may be used successfully to collect personnel utilization data in a physical therapy department.
