Resumen de A preliminary model for the impact of Research and development in health care expenditure: the case of Costa Rica
This paper describes a simple model for estimating costs in the National Health System in Costa Rica that includes technology-related lag. Model parameters are associated to the system (technical lag, specialist lag and medication lag) and to the patient (severity of illness). Preliminary results suggest that (1) the model follows a GDP estimate within a 1.65% error in a simulated period of 11 years, (2) the model is accurate in accounting for the cost of attention in health services and (3) proposed R&D interventions that concentrate on solving problems related to critical parameters do have a significant effect on final national budget estimates under the assumptions of this model.
