Objective: To investigate the current status and influencing factors of medication adherence in hospitalized elderly patients with depression, so as to provide evidence for clinical targeted interventions and improvement of treatment prognosis. Methods: A cross-sectional study was conducted, enrolling 320 hospitalized elderly patients with depression in our hospital. Sociodemographic characteristics, lifestyle, health status, and psychosocial indicators were collected. Medication adherence was assessed using the 8-item Morisky Medication Adherence Scale(MMAS-8). Multivariate ordinal logistic regression analysis was performed to identify independent influencing factors. Results: The overall medication adherence of the patients was at a moderate to low level, with 30.6%(98/320) having high adherence, 38.1%(122/320) having moderate adherence, and 31.3%(100/320) having low adherence. Univariate analysis showed that age, educational level, married living alone, drinking history, comorbid underlying diseases, sleep disorders, Patient Health Questionnaire-9(PHQ-9) score, Generalized Anxiety Disorder-7(GAD-7) score, Perceived Stress Scale-10(PSS-10) score, and Social Support Rating Scale(SSRS) score were all significantly correlated with medication adherence(all P<0.05). Multivariate ordinal Logistic regression analysis revealed that higher educational level(OR=2.86, 95%CI 1.79-4.57), married status(OR=2.27, 95%CI 1.48-3.49), and higher SSRS score(OR=1.21, 95%CI 1.14-1.28) were independent protective factors for medication adherence. In contrast, age(OR=0.86,95%CI 0.81-0.91) living alone(OR=0.46, 95%CI 0.29-0.72), presence of sleep disorders(OR=0.41, 95%CI 0.27-0.62), higher PHQ-9 score(OR=0.76, 95%CI 0.70-0.82), higher GAD-7 score(OR=0.79, 95%CI 0.72-0.87), and higher PSS-10 score(OR=0.84, 95%CI 0.79-0.89) were independent risk factors(all P<0.001). The constructed prediction model exhibited good discriminative ability(AUC=0.84). Conclusion: Medication adherence in hospitalized elderly patients with depression is jointly influenced by multidimensional factors including sociodemographic, health, and psychosocial factors. Clinical interventions should focus on and integrate assessment of marital and living status, sleep disorder management, emotional regulation, and social support system enhancement to formulate individualized strategies, thereby effectively improving medication adherence. |
