The appropriate level of bed occupancy is prerequisite to the efficient management of hospitals. From this point of view, the paper intends to identify some factors that are interrelated with bed occupancy rate in Korean Hospital. The data used were taken from 1973 hospital census through the courtesy of the Korean Hospital Association. Included in the census are 198 hospitals. However, this study excluded 66 hospitals to include only those that are considered to be short term general hospitals and that have reliable information. Among those excluded from the analysis, 45 hospitals are tuberculosis hospitals, leprosy hospitals, mental hospitals, dental hospitals, or other single specialty hospitals, and 21 hospitals had incomplete data. Thus the analysis was made on 132 hospitals. Information on several characteristics of the area, where the hospitals are located, was collected from government statistics.
This variables considered as associated factors of bed occupancy are classified into four groups: 1) context and input volume 2) manpower mix, 3) indicators for hospital utilization, and 4) characteristics of administrative unit where the hospital is located. As variables for context and input volume, post-graduate clinical training status, organization responsible for operation, number of available beds, number of employees, number of staff physician per 100 beds, number of special areas with specialist physicians, number of nurses per 100 beds, and number of total employees per bed were included. Manpower mix variables used were number of trainee physicians per a staff physician number of employees excluding trainee physicians per a staff physician, number of nurses per a staff physician, and percentage of staff physicians over total employees. Indicators for hospital utilization considered in this analysis were number of daily outpatient visits per a staff physician, average length of stay, and annual bed turn-over. Included in the characteristics of hospital site were population size, population density, local tax revenue per person, number of enrollment in the middle school or above per 1,000 population, number of enrollment in college or university per 1,000 population, and number of private clinics per 100,000 population of the area where the hospital is located.
Among the above variables considered, all the variables, except number of daily outpatient visits per a staff physician and number of enrollment in middle school or above per 1,000 population, appeared to have significant associations with bed occupancy rate. In summary, it was observed that characteristics of area of location as well as hospital characteristics are interrelated with bed occupancy rate. This suggests that the efficient management of hospitals requires careful considerations in hospital characteristics and their location altogether. Hospital characteristics should be fitted to various characteristics of the community where it is located
