Various studies have established that adequate staffing in hospitals is associated with improved clinical outcomes among patients; patients with diabetes have been reported to have better outcomes with a higher provider-to-patient ratio.

The International Society for Pediatric and Adolescent Diabetes Clinical Practice Guidelines, 2022, suggest an optimal resource allocation of 1.0 to 1.25 diabetes nurses, 0.75 to 1.0 pediatric diabetologists, 0.5 dietitians, and 0.3 social workers/psychologists per 100 patients.
However, when considering the population with type 1 diabetes (T1D), where a team of providers, including nurses, diabetes educators, doctors, etc, plays a role in patient glycemic management, there are no studies that have looked at describing the provider staffing ratio in pediatric and adult endocrinology centers.
