Introduction: Proper distribution of human resources is an important factor ensuring high-quality performance and sustained service quality. The aim of this study was determining the workload pressure among medical officers in health clinics (HCs) in Kelantan. Method: A record review survey was conducted between January and April 2019 using human resources data for 2018 involving HCs in Kelantan. It included all the HCs in Kelantan and excluded community clinics. Workload pressure was determined using a tool known as Workload Indicator of Staffing Needs, developed by World Health Organization. A high workload pressure was defined as a ratio between required and acquired medical officers of less than 1. The data were presented descriptively using as frequencies and percentages. Results: All 85 HCs in Kelantan were involved in the study; 90% (9/10) of the Kelantan districts recorded high work- load pressure. Moreover, 68.2% (58/85) HCs had high workload pressure. Tanah Merah, Tumpat, Pasir Mas, and Kota Bharu had the most HCs with high workload pressure, and most such HCs were found in areas with a high-den- sity population, requiring huge coverage. Conclusion: The Kelantan State Health Department should develop better human resource distribution strategies to ensure the sustainability of quality care in HCs.
