Effects of Integrated Palliative Care Intervention on Quality of Life in Terminal Cancer Patients: A Meta-analysis / 한국호스피스완화의료학회지

ABSTRACT

PURPOSE: This study was conducted to evaluate the effects of integrated palliative care intervention on quality of life in terminally ill patients. METHODS: A comprehensive literature search was performed via PubMed, Cochrane Library CENTRAL, LWW (Ovid), CINAHL and several Korean databases. The main search strategy was to combine terms indicating palliative care intervention, presence of terminal illness and study design. Methodological quality was assessed using Cochrane's Risk of Bias for randomized studies and Risk of Bias Assessment tool for non-randomized studies. Data were analyzed by the Stata 10 program. RESULTS: Eight clinical trials met the inclusion criteria with a total of 356 participants. Integrated palliative care interventions were administered for a mean of 6.5 weeks, 5.6 sessions and an average of 47.8 minutes per session. Effect sizes were heterogeneous, and subgroup analysis was done. Integrated palliative care interventions had a significant effect on quality of life (ES=1.83, P=0.018, l2=92%), spiritual well-being (ES=0.78, P=0.040, l2=0), depression (ES=0.86, P<0.001, l2=32) and anxiety (ES=0.69, P=0.041, l2=71.1). But integrated palliative care interventions had no significant effect on pain (ES=0.365, P=0.230, l2=69.8). CONCLUSION: Results support findings that integrated palliative care interventions were helpful in lessening depression and anxiety and improving quality of life and spiritual well-being, however, the interventions did not assist pain management in terminal cancer patients. These findings suggest that various integrated palliative care interventions can assist terminal cancer patients with better quality of life in the socio-psycho-spiritual dimension.
