Factors associated with distinct prognostic-awareness-transition patterns over cancer patients' last 6 months of life.

ABSTRACT:

Background

Cancer patients may develop prognostic awareness (PA) heterogeneously, but predictors of PA-transition patterns have never been studied. We aimed to identify transition patterns of PA and their associated factors during cancer patients' last 6 months.

Methods

For this secondary-analysis study, PA was assessed among 334 cancer patients when they were first diagnosed as terminally ill and monthly till they died. PA was categorized into four states: (a) unknown and not wanting to know; (b) unknown but wanting to know; (c) inaccurate awareness; and (d) accurate awareness. The first and last PA states estimated by hidden Markov modeling were examined to identify their change patterns. Factors associated with distinct PA-transition patterns were determined by multinomial logistic regressions focused on modifiable time-varying variables assessed in the wave before the last PA assessment to ensure a clear time sequence for associating with PA-transition patterns.

Results

Four PA-transition patterns were identified: maintaining accurate PA (56.3%), gaining accurate PA (20.4%), heterogeneous PA (7.8%), and still avoiding PA (15.6%). Reported physician-prognostic disclosure increased the likelihood of belonging to the maintaining-accurate-PA group than to other groups. Greater symptom distress predisposed patients to be in the still-avoiding-PA than the heterogeneous PA group. Patients with higher functional dependence and more anxiety/depressive symptoms were more and less likely to be in the heterogeneous PA group and in the still-avoiding-PA group, respectively, than in the maintaining- and gaining-accurate PA groups.

Conclusions

Cancer patients heterogeneously experienced PA-transition patterns over their last 6 months. Physicians' prognostic disclosure, and patients' symptom distress, functional dependence, and anxiety/depressive symptoms, all modifiable by high-quality end-of-life care, were associated with distinct PA-transition patterns.

Project description:BACKGROUND:The purpose of this study was to examine the differences of timewise changes in life-space mobility between elderly people living alone and those living with others among community-dwelling elderly people from a day care facility with a rehabilitation service for seniors. METHODS:The present study used a longitudinal design with repeated measures every 3?months. In conformity with our inclusion criteria, this study included 233 community-dwelling elderly users of a day care facility with rehabilitation services for seniors in Japan. We analyzed the life-space assessment (LSA) scores collected at five time points (baseline, 3?months, 6?months, 9?months, and 12?months) using mixed-effects models with random intercepts and slopes over time. In the present study, the explanatory variables of interest were time, and living situation (living alone or with others). As possible confounders, we considered the following: (a) age, (b) sex, (c) social frailty, (d) physical frailty, (e) mild cognitive impairment (MCI), (f) depression, and (g) economic satisfaction. RESULTS:The mean age of participants was 78.9?years (SD?=?7.7), their mean LSA score was 60.1 points (SD?=?25.7), and 42.9% of the participants were men. After adjusting for age, gender, frailty, depression, MCI, and economic satisfaction, the mean LSA score of older adults who lived with others was significantly lower (7.42 points, 95%CI?=?-?18.30 to -?0.15, p?=?0.048) than that older adults who lived alone. DISCUSSION:Community-dwelling older adults who used a day care center with rehabilitation services and lived with others had a smaller life-space at baseline than those who lived alone. This suggests that there is a need to pay more attention to social frailty among both older adults who live alone and those who live with others. CONCLUSIONS:According to a multilevel analysis growth model, elderly persons who lived with others had significantly lower life-space mobility than those who lived alone.
