2206Prevalence and determinants of complicated grief in bereaved caregivers of patients admitted for cardiovascular diseases
European Heart Journal(2019)
Abstract
Abstract Introduction Few studies have examined complicated grief in bereaved caregivers of patients with cardiovascular diseases (CVD), in contrast with studies in caregivers of patients with cancers. We examined the prevalence and determinants of complicated grief among bereaved caregivers of patients with CVD. Methods We conducted a cross-sectional survey using a self-administered questionnaire for bereaved family members of CVD patients who had died in the cardiology departments of 9 tertiary care centers in Japan. We assessed bereaved caregiver grief status using the Brief Grief Questionnaire (BGQ), and its association with their depression (Patient Health Questionnaire-9 [PHQ-9]). Questionnaire also covered following associated factors: bereaved family member and patient characteristics, end-of-life care (Care Evaluation Scale [CES], a scale for assessment of the structure and process of care); and the quality of the deceased patients' death (Good Death Inventory [GDI]). Results A total of 269 bereaved caregivers (mean age, 64±12 years; 35% male) of patients with CVD (heart failure n=155 myocardial infarction n=32, cardiopulmonary arrest n=15, arrhythmia n=8, and others n=59) were enrolled in the study. Overall, 14.1% of the bereaved caregivers had complicated grief (BGQ≥8), 32.3% had subthreshold complicated grief (BGQ=5–7), and 13.3% had depression (PHQ-9≥10). Bereaved caregivers with complicated grief frequently developed depression (58% vs. 6%, p<0.001). Among the bereaved caregivers with complicated grief, the assessment of end-of-life care was worse (CES score: 28 [21–40] vs. 23 [19–39], p=0.04), and the assessment of the deceased patients' quality of death tended to be worse (GDI score: 4.0 [3.0–4.8] vs. 4.3 [3.7–4.9], p=0.05). The cause of admission as well as preferences of the patient and family (e.g., treatment [focusing on extending life vs. relieving discomfort], desire for information, place of end-of-life) were not associated with the prevalence of complicated grief. The prevalence of complicated grief was associated with loss of a spouse, poor psychological health during the deceased patients' admission, and poor preparation for the patient's imminent death (all p<0.05). Bereaved caregivers with complicated grief had experienced more decisional burdens regarding the deceased patients' treatment (55% vs. 25%, p=0.001). Notably, 64% of bereaved caregivers with complicated grief were not treated (i.e., neither routine follow-up by psychiatrists/psychotherapist nor prescription for anti-depressants/tranquilizers). Conclusions The prevalence of complicated grief of bereavement was 14.0%. When subthreshold complicated grief was included, the prevalence of complicated grief increased to include half of the caregivers; therefore, routine screening of the bereaved could be recommended. Clinicians should pay particular attention to bereaved families with high risk factors to identify those at risk for future development of complicated grief.
