Psychological effect of physical function dependence on maintenance hemodialysis patients and their primary family caregivers / 中华肝脏病杂志

ABSTRACT

Objective: To investigate the psychological effect of physical function dependence on maintenance hemodialysis (MHD) patients and their primary family caregivers. Methods: The study was a cross-sectional survey. The MHD patients in the hemodialysis centre, the Third Affiliated Hospital of Guangzhou Medical University from March 2022 to June 2022 were enrolled. The patients' demographics and laboratory data were collected. Katz and Lawton-Brody questionnaires were used to assess patients' physical function, and Five Item Mental Health Inventory (MHI-5) was used to evaluate the psychological conditions of the patients and their primary family caregivers. Multiple linear regression analysis was used to analyze the influencing factors of MHI-5 scores of the patients and their primary family caregivers. Results: A total of 116 patients were included, with 61 males and 55 females. There were 47 patients (40.5%) with physical function dependence. In the physical function dependence group, serum albumin (t=-2.512, P=0.013), MHI-5 scores of patients and their primary family caregivers (t=-8.461, P < 0.001; t=-8.533, P < 0.001) and male ratio (χ2=8.467, P=0.002) were significantly lower, and the age (t=9.754, P < 0.001) and the proportions of hypertension (χ2=20.421, P < 0.001), diabetes (χ2=10.470, P=0.002), cardiovascular and cerebrovascular diseases (χ2=9.898, P=0.003) were significantly higher than those in the normal physical function group. The incidence of mental disorders in MHD patients was 39.7%(46/116), and the incidence of mental disorders in the physical function dependence group was significantly higher than that in the normal physical function group [72.3%(34/47) vs. 17.4%(12/69), χ2=35.275, P < 0.001]. The incidence of mental disorders in the primary family caregivers was 32.8%(38/116), and the incidence of mental disorders in the primary family caregivers of physical function dependence group was significantly higher than that in the normal physical function group [66.0%(31/47) vs. 10.1%(7/69), χ2=39.536, P < 0.001]. The incidence of mental disorders in the primary family caregivers of MHD patients who were not spouses was significantly higher than that of spouses [46.0%(29/63) vs. 17.0%(9/53), χ2=11.028, P=0.001], and in physical function dependence group, the incidence of mental disorders in non-spouses was significantly higher than that in spouses [80.6%(25/31) vs. 37.5%(6/16), χ2=8.749, P=0.003]. Multiple linear analysis showed that bathing (β=-5.182, P=0.015), doing laundry (β=-7.053, P < 0.001), taking medication (β=-8.680, P=0.003), and female patients (β=-2.982, P=0.030) were the influencing factors of MHI-5 scores decline in MHD patients. Bathing (β=-4.404, P=0.032), preparing meals (β=-3.954, P=0.041), managing money (β=-5.067, P=0.021), and female patients (β=-2.466, P=0.042) were the influencing factors of MHI-5 scores decline in primary family caregivers. Conclusions: The incidence of physical function dependence in MHD patients is high, and its manifestations and influencing factors are diverse. The incidence of mental disorders in MHD patients and their primary family caregivers is also high, especially in patients with physical function dependence and non- spouse family caregivers. Clinicians should pay attention to and assess the physical function dependence of MHD patients as early as possible, and intervene in time. At the same time, they should also pay attention to the mental health of MHD patients and their primary family caregivers.
