有人提出，对疗养院人口进行抽样的两种常用方法，即横断面抽样和出院抽样，会产生具有不同特征和住院时间的样本。尚未研究将这些样本与疗养院入院样本进行比较。本研究比较了横截面样本、出院样本和入院样本的特征和住院时间。 1987年2月三所疗养院的所有现有居民构成横断面样本，所有次年入院样本构成入院样本，所有当年出院样本构成出院样本。比较这三种抽样技术的结果表明，最显着的差异发生在横截面样本和准入样本之间。与入院样本中的人相比，横断面样本中的人往往在疗养院停留的时间更长，社会支持更少，行为和功能问题更多，而入院样本中的人往往停留时间更短，医疗问题更严重。与横截面样本相比，出院样本与入院样本更相似；然而，出院样本和入院样本之间存在一些差异。根据三个样品之间发现的差异，讨论了每个样品的适当用途。
It has been suggested that two common methods of sampling nursing home populations, cross‐sectional sampling and discharge sampling, result in samples with different characteristics and lengths of stay. Comparison of these samples to a sample of nursing home admissions has not been studied. This study compares characteristics and lengths of stay among cross‐sectional, discharge, and admission samples. All current residents of three nursing homes in February 1987 made up the cross‐sectional sample, all admissions in the following year made up the admission sample, and all discharges in the same year made up the discharge sample. The results of comparing these three sampling techniques show that the most striking differences occur between the cross‐sectional sample and the admission sample. Persons in the cross‐sectional sample tended to have longer nursing home stays as well as less social support and more behavioral and functional problems than persons in the admission sample, who tended to have shorter stays and more acute medical problems. The discharge sample was more similar to the admission sample than it was to the cross‐sectional sample; however, some differences were found between the discharge and admission samples. Based on the differences found among the three samples, appropriate uses for each sample are discussed.
