Abstract

Objectives: To examine associations between family surrogates' bereavement outcomes and four previously determined quality of dying and death (QODD) latent classes (high, moderate, poor-to-uncertain, and worst).

Design: Prospective, longitudinal, observational study.

Setting: Medical ICUs at two academically affiliated medical centers in Taiwan.

Patients/participants: Three hundred nine family surrogates responsible for decision-making for critically ill patients at high risk of death (Acute Physiology and Chronic Health Evaluation II scores > 20) from a disease.

Interventions: None.

Measurements and main results: Participants were assessed by the depression and anxiety subscales of the Hospital Anxiety and Depression Scale, the Impact of Event Scale-Revised, 11 items of the Prolonged Grief Disorder (PGD) scale, and the Medical Outcomes Study 36-Item Short-Form Health Survey at 1, 3, 6, 13, 18, and 24 months post-loss. We simultaneously examined associations of four QODD latent classes with physical and mental health-related quality of life (HRQOL) and symptoms of anxiety, depression, post-traumatic stress disorder (PTSD), and PGD assessed over 24 bereavement months using multivariate hierarchical linear modeling. Surrogates' distinct QODD latent classes assessed at 1-month post-loss were significantly associated with bereavement outcomes, except for physical HRQOL and PGD symptoms. Significantly more depressive symptoms and worse mental HRQOL (β [95% CI]) were reported by bereaved surrogates in the moderate (1.958 [1.144-2.772], -2.245 [-3.961 to -0.529]), poor-to-uncertain (2.224 [1.438-3.010], -7.026 [-8.683 to -5.369]), and worst (2.081 [1.215-2.964], -4.268 [-6.096 to -2.440]) QODD classes than those in the high QODD class. Bereaved surrogates in the moderate (2.095 [1.392-2.798]) and poor-to-uncertain (0.801 [0.123-1.480]) QODD classes reported more anxiety symptoms, whereas those in the poor-to-uncertain QODD class suffered more PTSD symptoms (2.889 [1.005-4.774]) than those in the high QODD class.

Conclusions: The four distinct QODD latent classes were significantly associated with ICU family surrogates' bereavement outcomes, suggesting targets to improve end-of-life care quality in ICUs.
