与男性相比，女性更有可能独自生活，因此更难以启动中风的紧急医疗系统。这项研究的目的是检查佩戴医疗警报设备的好处，以激活独居老年妇女的紧急医疗系统。这是一项随机、对照的初步试验。从密歇根州东南部招募了60岁以上至少有1个中风危险因素的女性。受试者接受医疗警报装置或对照品。主要结局是从基线到佩戴器械或对照品90天的健康相关生活质量（HRQOL）变化。无法达到320例的计划样本量，在数据检查前，试验在265例随机分配的女性中停止。平均而言，治疗组年龄较大，报告的高胆固醇患病率较低，完成随访的可能性较小。与对照组（2.23）相比，干预组（0.46）在过去一个月内的健康天数损失较小（p= 0.213）。同样，治疗组和对照组的焦虑、抑郁和感知孤立的变化的次要结果也没有差异。这项研究没有确定佩戴该设备的女性与未佩戴该设备的女性相比HRQOL的改善，也没有确定研究医疗警报设备在老年女性中的有效性的可行性。使用蜂窝技术的较新设备可能比本研究中使用的基于固定电话的系统更容易接受。
Women are more likely to live alone compared with men, and therefore have more difficulty activating emergency medical systems for stroke. The goal of this study was to examine the benefit of wearing medical alert devices to activate emergency medical systems for elderly women living alone. This was a randomized, controlled pilot trial. Women over 60 with at least 1 stroke risk factor were recruited from Southeast Michigan. Subjects received either a medical alert device or control. The primary outcome was change in health-related quality of life (HRQOL) from baseline to 90 days of wearing the device or control. A planned sample size of 320 could not be reached, and the trial was stopped at 265 women randomized prior to data examination. On average, the treatment group was older, reported lower prevalence of high cholesterol, and was less likely to complete follow-up. There was a nonsignificant smaller loss of healthy days in the past month in the intervention group (0.46) compared with the control group (2.23) (p= 0.213). Similarly, the secondary outcomes of changes in anxiety, depression, and changes in perceived isolation did not differ by treatment and control groups. This study did not establish improvement in HRQOL among women who wore the device compared with those that did not, nor the feasibility of a trial to study the efficacy of medical alert devices in elderly women. Newer devices that use cellular technology may be more accepted than the landline-based system used in this study.
