This study compared different methods for collecting data on falls among people with dementia to identify which is most feasible and accurate. Eighty-three dyads, comprised of a community-dwelling person with dementia and their informal carer, participated in the TAi ChI for people with demenTia (TACIT) trial. Falls were collected prospectively over 6 months using monthly calendars, weekly and monthly telephone interviews, and 3-monthly telephone interviews with the carer. Unique falls identified across the reporting methods were combined, and this total was compared against each reporting method in isolation and combinations. A higher frequency of falls indicated greater accuracy. Falls data collection was most feasible with weekly telephone interviews (84%), and most accurate with the combination of weekly telephone interviews with monthly calendars (96%). For the greatest completeness and accuracy of falls data with community-dwelling people with dementia, researchers should use both weekly telephone interviews and monthly calendars.

收集老年痴呆症患者跌倒数据的不同方法的可行性和准确性。

这项研究比较了收集痴呆症患者跌倒数据的不同方法，以确定哪种方法最可行和最准确。八十三对，包括居住在社区的痴呆症患者和他们的非正式照顾者，参加了痴呆症患者太极 (TACIT) 试验。使用月历、每周和每月电话采访以及每 3 个月与照顾者的电话采访，在 6 个月内前瞻性收集跌倒。将通过报告方法确定的独特跌倒合并，并将此总数与单独和组合的每种报告方法进行比较。更高的跌倒频率表明更高的准确性。每周电话采访（84%）是最可行的跌倒数据收集，最准确的是将每周电话采访与月度日历相结合（96%）。为了获得社区痴呆症患者跌倒数据的最大完整性和准确性，研究人员应使用每周电话采访和每月日历。
