Job responsibilities are significantly accomplished with sufficient and appropriate labor, although it differs in various fields. A major challenge in health facilities involves the ability to balance the number of staff and workloads to ensure quality, effective and efficient performance. Developing countries continue to struggle, in terms of fulfilling these objectives, mainly due to limited resources and budget. Therefore, this study aimed to analyze the workload at the Pharmacy of Universitas Padjadjaran Dental and Oral Hospital (RSGM Unpad) using WHO’s workload indicators of staffing needs (WISN) technique. This study also applied a descriptive cross-sectional design and conducted the WISN methodology between May-September 2020. Subsequently, observations, discussions and interviews were used to generate relevant information from the hospital’s workforce and its 2019 records. The results showed the availability of 7 employees and an annual estimate of 97,440 minutes in work duration. As a consequence, the manpower demands for inpatient-outpatient and logistic-purchasing departments were 4 and 2 persons, respectively. The resulting WISN ratio was 1.17 (> 1), indicating an inadequate workload and staff number. Based on the WISN analysis, it is concluded that the pharmacy is overstaffed under the existing workload conditions. Therefore, employee redistribution and the development of pharmaceutical satellites towards enhancing effectiveness and efficiency are significantly recommended.
