Family dynamics in a multi-ethnic Asian society: comparison of elderly CKD patients and their family caregivers experience with medical decision making for managing end stage kidney disease.

backgroundElderly end stage kidney patients face a decision concerning whether or not to initiate dialysis. In Asia, this decision is highly influenced by family caregivers. The objective of this paper was to understand patients' experience with and preferences for family involvement in treatment decisions, and via a series of hypothetical vignettes, to identify whether there was discordance in treatment preferences between patients and their caregivers, and how any potential conflicts were reconciled.

methodsWe conducted a survey with 151 elderly (aged ≥65) chronic kidney disease patients and their caregivers at outpatient renal clinics. The survey asked, when making treatment decisions, whom they wish makes the final decisions (i.e., preference) and who usually makes the final decisions (i.e., experience). The survey also presented a series of choice vignettes for managing patient's condition and asked respondents to choose between two hypothetical treatment profiles in each vignette. Patients and caregivers were first interviewed separately in tandem, and then were brought together to choose a treatment jointly for vignettes where the initial treatment choice differed within the dyad. We used multivariate regressions to investigate the predictors of discordance and reconciliation.

resultsWe found that most (51%) patients preferred and experienced (64%) significant involvement from caregivers. However, 38% of patients preferred to make final decisions alone but only 27% of patients did. In the hypothetical vignettes, caregivers chose the more intensive option (i.e., dialysis) more than patients did (26% vs 19%; p < 0.01). Overall, 44% of the dyads had discordance in at least 3 vignettes, and the odds of discordance within patient-caregiver dyads was higher when caregivers chose dialysis or treatment with the higher cost (p < 0.01). In half the cases, discordance resolved in the patients' favor, and this was more likely to be the case if the patient was employed and wanted to be in charge of final decisions (p < 0.01).

conclusionsOur results highlight the important role of caregivers in decision-making but also the potential for them to overstep. Clinicians should be aware of this challenge and identify strategies that minimize the chances that patients may receive treatments not consistent with their preferences.
