Differences in patients accessing inpatient versus outpatient palliative care at time of referral at a cancer centre

Outpatient palliative care clinics are a new and developing area of service delivery that can respond to increasing demand and facilitate earlier contact in the illness trajectory. Work is needed to standardise the criteria for referral to outpatient palliative care services and clarify which patients are likely to benefit the most from this mode of support. This study aimed to describe the demographic, clinical and symptom profile, and survival of patients referred to a newly established hospital-based integrated palliative care program. Comparisons were made between patients initially seen as outpatients versus those seen as inpatients. A retrospective population was identified from routinely collected hospital admitted inpatient and ambulatory databases comprising adult cancer patients receiving a new referral to the service during a 6-month period. Patients were grouped into two cohorts according to the setting of their first palliative care assessment and followed to death or study censor date. During the study period, 473 new referrals were made comprising 229 (48%) patients initially seen as outpatients and 244 (52%) initially seen as inpatients. The outpatient cohort had higher performance status, experienced higher symptom burden, lived longer, had fewer inpatient admissions, and received earlier referral to palliative care resulting in greater palliative care involvement up to their death (all p < .05). Early palliative care can be effectively delivered by an outpatient palliative care service for cancer patients who are experiencing symptom burden but are otherwise functional. These cases lived longer and had fewer subsequent inpatient visits, demonstrating the preliminary effectiveness of this integrated service.
