Many OECD countries are at the heart of the political agenda regarding rising healthcare spending and its long-term sustainability. The continuous rise in health expenditure exerts pressure on government budgets, health services and personal patient finance. This has led policy makers to implement reforms in order to mitigate pressures on these costs, as well as introduce programs and forecasting models to provide a support tool capable of adapting to issues that may arise. The purpose of this study is to investigate the best model to predict total health spending in the USA, a country with the highest global spending, using the Box-Jenkins methodology. Applying annual data for total US health expenditure from 1900 to 2017, resulted in the ARIMA (2,1,0) model with static forecasting being the most appropriate to predict these costs. Model estimation was achieved by the maximum likelihood-ML method and finally, the accuracy of the forecast was assessed based on certain criteria such as the root mean square error (RMSE), mean absolute percentage error (MAPE) and Theil’s inequality coefficient.
