The impact of palliative care training for oncologists and integrative palliative service in a public-funded hospital cluster-a retrospective cohort study.

Abstract

Oncological care of advanced cancer patients was provided by multiple departments in Hong Kong. One of these departments, the clinical oncology department (COD), introduced systematic palliative care training for its oncologists since 2002. The COD was recognized as a European Society for Medical Oncology (ESMO) Designated Centre of Integrated Oncology and Palliative Care since 2009. This retrospective cohort study aims to review the impact of integrative training and service on palliative care coverage and outcome. Clinical information, palliative service provision, and end-of-life outcomes of patients who passed away from lung, colorectal, liver, stomach, or breast cancer in the Hong Kong West public hospital network during July 2015 to December 2015 were collected. A total of 307 patients were analyzed. Around half (49.2%) were attended primarily by COD, and 68.9% received palliative service. There are significantly fewer patients referred to palliative care from other departments (p < 0.001), with only 19.9% of this patient group receiving palliative referral. COD patients had longer palliative coverage before death (median 65days versus 24days, p < 0.001), higher chance of receiving end-of-life care at hospice units (36.4 versus 21.2%, p = 0.003), lower ICU admission (0.66 versus 5.1%, p = 0.02), and higher percentage of receiving strong opioid in the last 30days of life (51.0 versus 28.9%, p < 0.001) compared to other departments. In multivariable analysis, COD being the primary care team (odds ratio 12.2, p < 0.001) was associated with higher palliative care coverage. The study results suggested that systematic palliative care training of oncologists and integrative palliative service model was associated with higher palliative service coverage and improved palliative care outcomes.
