Effects of hospice palliative care on medical service utilisation by patients on prolonged mechanical ventilation: A nationwide cohort study

Abstract

\n Background: Several studies have shown that hospice palliative care interventions for cancer patients can reduce medical utilisation. In Taiwan, 20–25% of mechanical ventilation patients have been on prolonged mechanical ventilation (PMV), but only a few studies have discussed the effectiveness of hospice palliative care on these patients. This study aimed to explore the effectiveness of medical utilisation on patients undergoing PMV in hospice palliative care.Methods: From the Health Insurance database of a nationwide population-based study, we identified patients who had been on mechanical ventilation for over 21 days, were 18 years or older between 2009 to 2017, and had undergone hospice palliative care. The control group was obtained by 1:1 matching using propensity scoring after excluding patients who had participated in palliative care for less than 15 or more than 181 days. Furthermore, we used conditional logistic regression analysis to explore intensive care unit readmission, emergency department presentation, and cardiopulmonary resuscitation incidents, 14 days prior to death.Results: A total of 186,533 new PMV patients aged ≥ 18 years with terminal diseases were admitted between 2009 and 2017. Additionally, the number of patients receiving palliative care increased annually, from 0.6% in 2009 to 41.33% in 2017. The number of prolonged mechanical ventilation during emergency visits (odds ratio [OR]=0.68, 95%CI: 0.63-0.74), intensive care unit hospitalisation (OR=0.59, 95%CI: 0.53-0.46), cardiopulmonary resuscitation (OR=0.40, 95%CI: 0.35-0.46), and total hospitalisation cost (USD 1319.9.57 ± 1821.67 vs. 1544.37 ± 2309.27) was lower in the palliative care group.Conclusion: Patients undergoing PMV whilst in hospice palliative care can significantly reduce total hospitalisation cost, intensive care unit admittance, cardiopulmonary resuscitation utilisation, and medical expenses at ≤14 days prior to death.
