Impact of palliative care (PC) consultation on quality of end-of-life (EOL) care in advanced cancer patients receiving care at a tertiary cancer center (TCC).

Abstract

129 Background: Early integration of PC with oncological care has been shown to improve outcomes in patients with advanced cancer, including quality of life and mood. It has also been suggested to have a positive impact on quality of EOL care. The purpose of our study was to examine how occurrence and timing of PC consultation are associated with quality of EOL care in advanced cancer patients receiving care at a Canadian TCC. Methods: In this retrospective study, patients who died between April 1, 2013 and March 31, 2014, had advanced cancer while receiving care at our TCC, and lived in the catchment area of our urban comprehensive integrated PC program were eligible. Date of death, demographics, and cancer type were obtained from the cancer registry. Date of diagnosis of advanced cancer was determined from electronic medical records. Occurrence and date of PC consultation were identified from the PC database. Data on quality of EOL care indicators were retrieved from the cancer registry, including, in the last 30 days of life: emergency room visits, hospital admission, hospitalization > 14 days, ICU admission, death in hospital, and chemotherapy use. Results: Of 1414 eligible patients, 1101 (77.9%) received PC consultation in hospital, outpatient clinic, or community. Patients who received PC consultation were younger than those who did not receive PC consultation (age 68.8 vs. 71.0, p = 0.01), and differed in the frequency of cancer types (p < 0.001), but not sex, marital status, or income. 679 patients (48.0%) had at least 1 indicator of quality of EOL care. Patients who did and did not receive PC consultation did not differ in the frequency of any indicators of quality of EOL care. There were also no differences in frequency of quality of EOL care indicators between patients who received their first PC consultation > 3 months vs. ≤3 months or > 6 months vs. ≤6 months before death. Conclusions: Among advanced cancer patients receiving care at our TCC, occurrence and timing of PC consultation did not affect quality of EOL care. Methodological and healthcare system differences may explain the discrepancy between our results and those of other investigators. Further research is needed.
