To provide an empirical base for bed reallocation within a hospital planning jurisdiction in Canada, this article proposes a population-based method to measure the distribution of acute care beds for each district and the service load for each hospital. The measure for the bed distribution (BDI) is the number of beds per 1,000 age-sex-adjusted number of residents in a district, while the service load of a hospital is measured by the number of persons being served per bed (SPI). The number of beds allocated to each district, or the number of persons served by each hospital, was estimated by applying the hospital service population model, which employs both relevance- and commitment-index methods. The method thus proposed was applied to Alberta data. It appears that both BDI and SPI measures are stable across the variation of methods or data sources, yet sensitive enough to detect changes over the years. Using these indexes, potentially over- or underbedded districts and over- or underloaded hospitals can be identified for further investigation so that possible reallocation of acute care beds among the hospitals may take place.
为在加拿大医院规划管辖范围内为床位重新分配提供实证依据，本文提出了一种基于人口的方法，用于衡量每个地区急性护理床位的分布情况以及每家医院的服务负荷。床位分布指标（BDI）是指一个地区每1000名年龄性别调整后的居民中的床位数，而医院的服务负荷则通过每张床位服务的人数（SPI）来衡量。分配给每个地区的床位数或每家医院服务的人数是通过应用医院服务人口模型估算得出的，该模型采用了相关性和承诺指数方法。所提出的方法应用于艾伯塔省的数据。结果表明，BDI和SPI指标在方法或数据源的变化中都很稳定，但又足够敏感，能够检测出多年来的变化。利用这些指标，可以识别出可能床位过多或过少的地区以及负荷过重或过轻的医院，以便进行进一步调查，从而可能在医院之间重新分配急性护理床位。
