Description of CME Course

Importance  Patient to staff ratios vary across US dialysis facilities and have been associated with patient outcomes in older adults.

Objective  To determine whether patient to nurse or patient to social worker staff ratios are associated with access to kidney transplant for adolescents and young adults.

Design, Setting, and Participants  Retrospective cohort study including patients aged 12 to 30 years who started dialysis between 2005 and 2019 at 8490 US facilities according to the US Renal Data System, the national end-stage kidney disease registry.

Exposures  Time-updated quartile of patient to nurse and patient to social worker ratios at dialysis facilities.

Main Outcomes and Measures  Fine-Gray models were used to relate the exposure to the incidence of waitlisting and kidney transplant, accounting for the competing risk of death. Subgroup analysis by age at dialysis initiation (<22 vs ≥22 years) was performed. Follow-up was censored in January 2020.

Results  A total of 54 141 participants were included (median age, 25 years [IQR, 21-28]; 54.4% male; 4.3% of Asian race, 35.3% of non-Hispanic Black race). The median patient to staff ratios were 14.4 patients per nurse (IQR, 10.3-18.9) and 91.0 patients per social worker (IQR, 65.2-115.0). During a median follow-up of 2.6 years, 39.9% of patients (n = 21 598) received a transplant. In adjusted analysis, the highest (vs lowest) quartile of patient to nurse ratios was associated with 14% lower incidence of transplant (subhazard ratio [SHR], 0.86 [95% CI, 0.82-0.91]). The highest (vs lowest) quartile of patient to social worker ratios was associated with lower incidence of waitlisting (SHR, 0.95 [95% CI, 0.91-0.99]) and transplant (SHR, 0.85 [95% CI, 0.81-0.89]). For both staff ratios, there was an interaction with age at dialysis initiation, such that the association was more pronounced in patients starting dialysis at younger than 22 years (SHR, 0.71 [95% CI, 0.65-0.78] for the highest vs lowest quartile for nursing; SHR, 0.74 [95% CI, 0.68-0.80] for social work) compared with those 22 years and older (SHR, 1.00 [95% CI, 0.94-1.06] for nursing; SHR, 0.96 [95% CI, 0.91-1.02] for social work) for the outcome of transplant.

Conclusions and Relevance  Adolescents and young adults receiving care at dialysis facilities with higher patient to staff ratios had reduced access to waitlisting and transplant, particularly if they were younger than 22 years of age at dialysis initiation.
