Abstract
Objetivo. Obtener estimaciones para el tamaño óptimo de unidades de hemodiálisis considerando los factores en la producción de este servicio. Material y métodos. Se realizó un estudio en México en 2009. Se analizan algunos métodos para calcular el tamaño óptimo de una unidad de hemodiálisis bajo diferentes condiciones: mercado monopolístico, en competencia perfecta y maximización de producción. Resultados. Una unidad óptima con base en los supuestos de este ejercicio de estimación debería de contar con: 16 dializadores (15 activos, uno de reserva) y una purificadora de agua que pueda abastecerlos. Además son necesarios un médico nefrólogo y cinco enfermeras por cada dos turnos, con cuatro turnos por día. Conclusión. Comparando lo óptimo con lo observado en estudios recientes de México, se observan ineficiencias en la operación, particularmente por desaprovechar tanto el potencial del equipo de filtrado de agua como el equipo de salud.
Objective. To estimate the optimum size for hemodialysis units to maximize production given capital constraints. Materials and Methods. A national study in Mexico was conducted in 2009. Three possible methods for estimating a unit's optimum size were analyzed: hemodialysis services production under monopolistic market, under a perfect competitive market and production maximization given capital constraints. Results. The third method was considered best based on the assumptions made in this paper; an optimal size unit should have 16 dialyzers (15 active and one back up dialyzer) and a purifier system able to supply all. It also requires one nephrologist, five nurses per shift, considering four shifts per day. Conclusion. Empirical evidence shows serious inefficiencies in the operation of units throughout the country. Most units fail to maximize production due to not fully utilizing equipment and personnel, particularly their water purifier potential which happens to be the most expensive asset for these units.
