Comparison of Survival Between Patients Receiving General Ambulatory Palliative Care and Patients Receiving Other Palliative Care - Analysis of Data of a Statutory Health Insurance Data
Abstract Background The care of palliative patients takes place as non-specialized and specialized care, in both ambulatory and stationary settings. However, palliative care is largely provided as non-specialized care in the ambulatory sector (AAPV). This study aimed to investigate whether the survival curves of AAPV patients differed from those of the more intensive palliative care modalities and whether AAPV palliative care was appropriate in terms of timing.Methods The study is based on claims data from a large statutory health insurance. The analysis included 4,177 patients who received palliative care starting in 2015 and who were fully insured one year before and one year after palliative care or until death. The probability of survival was observed for 12 months. Patients were classified into group A, which consisted of patients who received palliative care only with AAPV, and group B including patients who received stationary or specialized ambulatory palliative care. Group A was further divided into two subgroups. Patients who received AAPV on only 1 day were assigned to Subgroup A1, and patients who received AAPV on two or more days were assigned to Subgroup A2. The survival analysis was carried out using Kaplan-Meier curves. The median survival times were compared with the log-rank test.Results The survival curves differed between groups A and B, except in the first quartile of the survival distribution. The median survival was significantly longer in group A (137 days, n=2,763) than in group B (47 days, n=1,424, p<0.0001) and shorter in group A1 (35 days, n=986) than in group A2 (217 days, n=1,767, p<0.0001). The survival rate during the 12-month follow-up was higher in group A (42%) than in group B (11%) and lower in group A1 (38%) than in group A2 (44%).Conclusions The results of the analysis revealed that patients who received the first palliative care shortly before death suspected insufficient care, especially patients who received AAPV for only 1 day and no further palliative care until death or 12-month follow-up. Palliative care should start as early as necessary and be continuous until the end of life.
