Clinical care ratios for allied health practitioners: an update and implications for workforce planning

Clinical care ratios are used to quantify and benchmark the activity of allied health professionals. This study aims to review previous recommendations and identify what variables may influence them.

Data was collected from the core allied health professions (audiology, nutrition and dietetics, occupational therapy, physiotherapy, podiatry, prosthetics and orthotics, psychology, social work and speech pathology) across eight Australian hospitals. Data for 113 staff who were casual or from smaller professions (audiology, podiatry, prosthetics and orthotics and psychology) were excluded due to insufficient numbers for analysis. The remaining data were analysed according to profession, seniority (tiers 1, 2 and 3) and employment status (permanent versus casual staff). A two-way ANOVA was performed to assess the association of clinical care ratios with tier, profession, employment status and gender.

Data from 1246 staff from the five larger professions at participating hospitals were analysed. There were no interactions between profession and gender (P = 0.185) or employment status (P = 0.412). The relationship between clinical care ratio and profession was modified by tier (interaction term, P = 0.014), meaning that differences in clinical care ratios between professions depended on the tier.

This research has confirmed that clinical care ratios are a useful tool in workload management and determining staffing levels for allied health professionals. The recommendations from this research provide a starting point that can be finessed with reference to profession, model of care, workforce structure, governance and training requirements. This will lead to increased staff wellbeing and improved patient outcomes.
