Technical Summary

Timely access to palliative care is associated with improvements in symptom management and quality of life, and has been shown to reduce the unnecessary use of acute care. General Practitioners (GPs) play a key role in providing palliative care for patients in the community; such as care planning, coordination, and referrals to specialist services. However, some evidence indicates inequalities in provision; for those with nonmalignant disease, and for people from ethnic minority groups.

This study will investigate the relationship between ethnicity and the recognition of palliative care needs for those with malignant and nonmalignant disease in England. The analysis will use de-identified routinely collected primary care data from the Clinical Practice Research DataLink (CPRD). A retrospective cohort of adult (18+) patients with completed ethnicity data, and a CPRD death date between (01/03/2018-to-29/02/2020) will be extracted. Extraction will include demographics, service utilisation, comorbidities and referrals. Records will be linked to Hospital Episode Statistics (HES) (inpatient/outpatient/acute) from the previous two years, including data on referrals and service utilisation. Records will also be linked to ONS death registration data and Index of Multiple Deprivation.

A recognition of palliative care needs variable (yes/no) will be created by identifying one of the following factors: palliative care QOF registration; palliative referral in CPRD/HES; palliative care treatment/main specialty (HES). A binary ‘length of palliative care’ variable (early/late) will be created from death date and the date of the first recognition of palliative care need. Descriptive statistics and data visualisation will be used to describe and illustrate patterns. Multi-level logistic regression and survival analysis will be used to examine ethnic and malignant/nonmaligant differences in: recognition of need; timing; and location/site (primary/secondary/acute). Associated clinical and demographic factors will be explored, and subgroup analysis undertaken. Findings will identify areas of ethnic inequality which may be used to inform targeted interventions.

Health Outcomes to be Measured

Primary outcomes:
1. Recognition of palliative care need by ethnic group (yes/no), variable created from presence of one of the following: palliative care local GP registration using (QOF Quality and Outcomes Framework) in CPRD; a referral to Palliative Medicine in CPRD; a referral to Palliative Medicine in HES; Palliative Medicine main specialty treatment or consultant code in HES.

2. Timing of referral by ethnic group (early/late), variable constructed from date of first recognition of palliative care need (see above) to date of ONS date of death) in days.

Secondary outcomes:
1. Healthcare setting recognising palliative care needs (primary care/secondary care/emergency care) by ethnic group
2. Other demographic and clinical associations for all outcomes.
