The purpose of this study was to test the utility of upper and lower extremity performance, grip strength, and mental status as predictors of stability or chronic deterioration in a cohort of frail older persons. The study population consisted of a random sample of forty patients selected from residents of an intermediate level care facility. Demographic information, manual ability, mental status, grip strength, mobility, active and resolved medical problems, medications, and professional's estimate of each participant's likelihood of requiring skilled nursing care were obtained within 2 weeks after identifying the sample. Manual ability, mental status, grip strength, and mobility were included in a Performance Index to predict functional ability. Study participants were followed for 2 years to observe which individuals remained at the intermediate care level and which persons required transfer to skilled nursing care. Of the 27 persons who completed the study, 21 persons remained stable (Group 1) and 6 individuals were transferred to skilled nursing care (Group 2) over the 2 year follow-up period. Group comparisons of the mean values revealed statistically significant differences for age, manual ability and the Performance Index. The Performance Index was a statistically significant predictor of increasing dependency (p less than 0.005). Within Group 1, no patients had a performance score which suggested a poor outcome; only one person in Group 2 had a prediction of the favorable outcome. Professional judgement correctly predicted 16 of the 21 persons in Group 1 and 2 of the 6 persons in Group 2.(ABSTRACT TRUNCATED AT 250 WORDS)
本研究的目的是检验上肢和下肢功能、握力以及精神状态作为体弱老年人稳定性或慢性衰退预测指标的效用。研究人群包括从一家中级护理机构的居民中随机抽取的40名患者。在确定样本后的2周内,收集了人口统计学信息、手部能力、精神状态、握力、活动能力、现患和已愈的医疗问题、用药情况以及专业人员对每位参与者需要专业护理可能性的评估。手部能力、精神状态、握力和活动能力被纳入一个表现指数,以预测功能能力。对研究参与者进行了2年的随访,观察哪些人仍处于中级护理水平,哪些人需要转至专业护理机构。在完成研究的27人中,21人保持稳定(第1组),在2年的随访期内,6人被转至专业护理机构(第2组)。均值的组间比较显示,年龄、手部能力和表现指数存在统计学上的显著差异。表现指数是依赖性增加的一个具有统计学意义的预测指标(p小于0.005)。在第1组中,没有患者的表现评分提示预后不良;第2组中只有一人被预测有良好预后。专业判断正确预测了第1组21人中的16人以及第2组6人中的2人。(摘要截选至250词)
