Keywords:
Activities of daily living, Anxiety, Depression, Health-related quality of life, Critical illness survivorsAbstract
Health-Related Quality of Life (HRQOL) affected by critical illness and ICU treatment, of those who have moved out of an intensive care unit. The sequela of critical illness contributes to Activity of Daily Living (ADL) problems, anxiety, and depression. This descriptive correlational study explored the relationship of HRQOL with ADL, anxiety, and depression among critically ill survivors in Chengdu Fifth People’s Hospital, Sichuan Province, the People’s Republic of China. The participants included 85 critical illness survivors. Research instruments included the demographic data of participants, and Chinese versions of the Short Form 36-item Health Status survey (SF-36), the Katz ADL scale, and the Hospital Anxiety Depression (HAD) Scale. The Cronbach’s alpha coefficient for the SF-36 was 0.98, 0.97, 0.99, 0.91, 0.96, 0.88, 0.87, and 0.91 for the physical function, role physical, role emotion, social function, bodily pain, vitality, mental health, and general health dimensions, respectively. For the Chinese version of the Hospital Anxiety Depression (HAD) Scale, the Cronbach's alpha coefficients for anxiety and depression were 0.84 and 0.83, respectively. The one-week test-retest reliability for the Katz ADL was 1.00. Descriptive statistics, Spearman’s rank correlation, and Mann-Whitney U tests were used in this study.
The study results showed that bodily pain received the highest HRQOL score in all dimensions among critical illness survivors (M = 91.54, SD = 16.80). The lowest average rating was for the general health dimension (M = 70.86, SD = 16.06). Role emotion, mental health, social function, physical role, physical function, and vitality were at the moderate average rating and were gradually declining, at 87.50, 86.22, 85.70, 80.10, 78.02, and 77.74, respectively. Most participants had ADL independence (n = 67, 78.80%). In addition, most participants showed no anxiety (n = 76, 89.50%) or depression (n = 75, 88.20%). Anxiety had a slight relationship with HRQOL in physical function and physical role (r = -.214, -.213, p < 0.05), a moderate relationship with general health (r = -. 454, p < 0.01), and a strong relationship with role emotion, social function, vitality, and mental health (r = -.514 to -.724, p < 0.01). In addition, depression had a moderate to strong negative relationship with HRQOL in seven dimensions except for the bodily pain dimension (r = -.478 to -.685, P < 0.01).
The results of this study provide evidence supporting strategies to enhance HRQOL among survivors of critical illness in Chengdu, Sichuan province. These strategies focus on improving activities of daily living as well as reducing anxiety and depression among this population.
