What determines duration of palliative care before death for patients with advanced disease? A retrospective cohort study of community and hospital palliative care provision in a large UK city
Objective For patients with advanced cancer, several randomised controlled trials have shown that access to palliative care at least 6 months before death can improve symptoms, reduce unplanned hospital admissions, minimize aggressive cancer treatments and enable patients to make choices about their end of life care, including exercising the choice to die at home. This study determines in a UK population the duration of palliative care before death and explores influencing factors. Design This retrospective cohort study analysed referrals to three specialist palliative care services; a hospital based inpatient palliative care team, and two community based services (hospices). For each patient referred to any of the above services we identified the date of first referral to that team and calculated the median interval between first referral and death. We also calculated how referral time varied by age, sex, diagnosis and type of palliative care service. Participants 4,650 patients referred to specialist palliative care services in Leeds UK between April 2012 and March 2014. Results Median age of the sample was 75 years. 3,903 (84.0%) patients had a diagnosis of cancer. Age, diagnosis and place of referral were significant predictors of duration of palliative care before death. Age was independently associated (J = 2672078, z = -392046.14, r = .01) with duration of palliative care regardless of diagnosis. Patients over 75 years have 29 fewer days of palliative care than patients under 50. Patients with non-cancer diagnoses have 13 fewer days of palliative care than patients with cancer. Additionally, patients referred to hospital palliative care receive 24.5 fewer days palliative care than those referred to community palliative care services. Conclusions The current timing of referral to palliative care may limit the benefits to patient in terms of improvements in end of life care, particularly for older patients and patients with conditions other than cancer
