Anesthesiologists in Uruguay: dynamic model to project the need of human resources in healthcare Modelo dinámico para proyectar la necesidad de recursos humanos en salud: anestesistas en Uruguay

Abstract

The aim of this study is to develop a dynamic model to simulate the supply of specialized physicians in Anesthesiology and estimate the gap with its demand, within Uruguay healthcare system. Methods A deterministic dynamic simulation model was developed and implemented using R software. Projections for the 2011-2050 period were analyzed, and the gap was estimated based on the equilibrium state of supply and demand. The quality of the model was evaluated comparing the simulated data with historical empirical data using goodness of fit indicators, such as the relative root mean square error (rRMSE). Results The demand and supply of anesthesiologists was projected for the period under analysis. A rRMSE<0,1 was obtained, which suggests the proposed model adequately reproduces the real offer dynamics. Based on the defined gap criteria, in the medium and long-term the situation is in equilibrium state. Conclusions The simulated model presents a good fit so that the human resources (HR) supply projection represents in a precise way the future availability of the workforce. Given that the model allows to evaluate the projection dynamics under different management scenarios, the model also represents an input of the utmost interest for management knowledgeable about human resource demands and healthcare policy.
