a Adapted from the 2020 USRDS Annual Data Report (United States Renal Data System, 2020).

The number of full- and part-time dialysis center staff in the United States has shown an increase from 2017-2018. However, approximately 5% of nursing positions remain unfilled, while ~2% of social worker and 1% of dietician positions remain unfilled.

Chart Explanation: 

The numbers of staffing positions continue to grow, although ~5% of nursing positions and ~2% of social worker and 1% dietitian positions remained unfilled in 2018. There were, on average, 14 dialysis patients for each registered nurse in 2018; there were about 109 patients per licensed vocation and licensed practical nurse, 61, patients for both dietitian, and social worker. There were 11 patients per patient care technician. The patient: staff ratios did not change substantially over the time period 2016 to 2018 (not shown in figure).

The United States Renal Data System (USRDS) is a national registry of all patients treated for end-stage renal disease (ESRD) in the United States. It is sponsored by the National Institute of Diabetes and Digestive and Kidney Disease (NIDDK) and the Centers for Medicare & Medicaid Services (CMS) that reports prevalence of all treated ESRD in the United States. U.S. population denominators are determined through U.S. Census data. Tables from the USRDS annual report (United States Renal Data System, 2020) are publicly available for download.
