(1) To compare staff members' opinions of long-term care (LTC) residents' ability to complete a customer satisfaction survey (CSS) with a measure of cognition (MDS-COGS) derived from Minimum Data Set data; and (2) to examine the association between CSS answer reliability and MDS-COGS score.
Retrospective comparison of the staff's assessment and MDS-COGS score for each respondent, as well as a prospective comparison of MDS-COGS scores with reliability measures from repeated survey administration.
A 100-bed Veterans Affairs (VA) nursing home.
We administered a CSS designed by our VA network following an assigned protocol. We later calculated each respondent's MDS-COGS score (grouped into 4 categories) and compared it with the staff's opinion of whether that resident was "capable of responding" (yes/no) to a CSS. We subsequently modified the CSS for low reading level and low vision, and randomly selected 40 LTC residents for repeated survey administration (T1 and T2 1 week later). Test-retest reliability was estimated by examining the extent to which T1 and T2 answers agreed (agreed exactly; meaningfully agreed as defined by VA network personnel who designed the survey; or meaningfully agreed as decided by paper authors).
Staff judged that 25 of 76 LTC residents were not and 51 of 76 were capable of responding to the CSS. In 82% of cases, MDS-COGS score category and staff opinion agreed ("no cognitive impairment"/"mild-moderate cognitive impairment" with "able to complete"; and "moderate-severe cognitive impairment"/"severe cognitive impairment" with "unable to complete"). Cohen's kappa was 0.57 with a P value of <0.001. Of the 40 LTC residents randomly selected for repeated survey administration, 32 successfully completed surveys at T1 and T2. Higher MDS-COGS scores, suggesting greater cognitive impairment, were significantly associated with lower answer reliability. The answers given by LTC residents changed meaningfully (by network criteria) from T1 to T2 by 12%, 27%, and 28% across categories of no-to-mild cognitive impairment, mild-to-moderate impairment, and moderate-to-severe impairment, respectively. The rate of decline in reliability, however, was small for each unit of increase in MDS-COGS.
Although the staff's opinions about residents' ability to complete a CSS were significantly associated with an objective MDS-COGS assessment, staff nonetheless failed on several occasions to let cognitively intact residents complete their own surveys. Although higher MDS-COGS scores were significantly related to lower reliability, there were no natural cut-points in the data to suggest a participate/do not participate line and the trend line between MDS-COGS level, and percent of questions answered reliably was not very strong. These results suggest that LTC residents with mild to moderate dementia might be capable of reliably answering certain types of customer satisfaction surveys.
(1)比较工作人员对长期护理(LTC)居民完成客户满意度调查(CSS)能力的看法与从最低数据集数据得出的认知测量指标(MDS - COGS);(2)研究CSS答案可靠性与MDS - COGS分数之间的关联。
对每个受访者的工作人员评估和MDS - COGS分数进行回顾性比较,以及对MDS - COGS分数与重复调查管理中的可靠性测量指标进行前瞻性比较。
一家拥有100张床位的退伍军人事务部(VA)疗养院。
我们按照指定方案实施了由我们的VA网络设计的CSS。随后,我们计算了每个受访者的MDS - COGS分数(分为4类),并将其与工作人员对该居民是否“能够回答”(是/否)CSS的看法进行比较。随后,我们针对低阅读水平和低视力情况对CSS进行了修改,并随机选择40名LTC居民进行重复调查管理(1周后的T1和T2)。通过检查T1和T2答案的一致程度(完全一致;按照设计该调查的VA网络人员定义的有意义的一致;或按照论文作者确定的有意义的一致)来估计重测信度。
工作人员判断76名LTC居民中有25名无法回答,51名能够回答CSS。在82%的情况下,MDS - COGS分数类别与工作人员的看法一致(“无认知障碍”/“轻度 - 中度认知障碍”对应“能够完成”;“中度 - 重度认知障碍”/“重度认知障碍”对应“无法完成”)。科恩kappa系数为0.57,P值<0.001。在随机选择进行重复调查管理的40名LTC居民中,32名在T1和T2成功完成了调查。较高的MDS - COGS分数表明认知障碍更严重,与较低的答案可靠性显著相关。LTC居民给出的答案在无至轻度认知障碍、轻度至中度障碍以及中度至重度障碍类别中,从T1到T2按照网络标准有意义地变化的比例分别为12%、27%和28%。然而,MDS - COGS每增加一个单位,可靠性下降的幅度很小。
尽管工作人员对居民完成CSS能力的看法与客观的MDS - COGS评估显著相关,但工作人员仍有几次未能让认知健全的居民完成他们自己的调查。尽管较高的MDS - COGS分数与较低的可靠性显著相关,但数据中没有自然的切点来表明参与/不参与的界限,并且MDS - COGS水平与可靠回答问题的百分比之间的趋势线不是很强。这些结果表明,轻度至中度痴呆的LTC居民可能能够可靠地回答某些类型的客户满意度调查。
