A Bayesian framework for describing and predicting the stochastic demand of home care patients

Home care providers are complex structures which include medical, paramedical and social services delivered to patients at their domicile. High randomness affects the service delivery, mainly in terms of unplanned changes in patients’ conditions, which make the amount of required visits highly uncertain. Hence, each reliable and robust resource planning should include the estimation of the future demand for visits from the assisted patients. In this paper, we propose a Bayesian framework to represent the patients’ demand evolution along with the time and to predict it in future periods. Patients’ demand evolution is described by means of a generalized linear mixed model, whose posterior densities of parameters are obtained through Markov chain Monte Carlo simulation. Moreover, prediction of patients’ demands is given in terms of their posterior predictive probabilities. In the literature, the stochastic description of home care patients’ demand is only marginally addressed and no Bayesian approaches exist to the best of our knowledge. Results from the application to a relevant real case show the applicability of the proposed model in the practice and validate the approach, since parameter densities in accordance to clinical evidences and low prediction errors are found

Bayesian analysis and prediction of patients’ demands for visits in Home Care

Home Care (HC) providers are complex structures which include medical, paramedical and social services delivered to patients at their domicile. High randomness affects the service delivery, mainly in terms of unplanned changes in patients’ conditions, which make the amount of required visits highly uncertain. In this paper, we propose a Bayesian model to represent the HC patient’s demand evolution over time and to predict the demand in future periods. Results from the application in a relevant real case validate the approach, since low prediction errors are found

A Bayesian approach for modeling patient's demand and hidden health status: an application to Home Health Care

Home Care (HC) service consists of providing care to patients at their own home, without the necessity of bringing them to hospitals or nursing homes. This service allows a high quality of life for the assisted patients and, at the same time, a cost reduction for the health care system. The aim of this paper is to propose a methodology for estimating and predicting the demand for care of HC patients in terms of number of visits and, at the same time describing the natural history of care profiles. We will model patients' holding times (i.e., the number of time slots the patient care profile does not change) as well as nurse visits to the patients
