Ethnicity and pre‐hospital care for people with suspected cardiac pain: cross‐sectional study

OBJECTIVES: Few studies have investigated the quality of pre‐hospital care by ethnicity. We aimed to investigate ethnic differences in pre‐hospital ambulance care of patients with suspected cardiac pain. METHODS: We conducted a cross‐sectional analysis of retrospective electronic clinical data for patients with suspected cardiac pain over one year (August 2011 to July 2012) extracted from a single regional ambulance service. This included patient demographic data, clinical measurements, drugs administered and outcomes, such as transportation to hospital or referral to primary care. We used multivariate regression to investigate differences in care by ethnicity comparing non‐White with White patients. RESULTS: There were 7046 patients with suspected cardiac pain, with 4825 who had ethnicity recorded including 4661 (96.6%) White and 164 (3.4%) non‐White. After correcting for age, sex, socio‐economic status and whether transported to hospital, non‐White patients were significantly more likely to have temperature [odds ratio (OR) 2.96, P = 0.007], blood glucose (OR 3.95, P = 0.003), respiratory rate (OR 4.94, P = 0.03) and oxygen saturation (OR 2.43, P = 0.006) recorded. Non‐White patients were significantly less likely to be transported to hospital (OR 0.43, P = 0.03). CONCLUSION: There were significant differences in pre‐hospital ambulance care for non‐White compared with White patients with suspected cardiac pain. These differences could be due to differences in clinical condition or case‐mix, language and cultural barriers, limited understanding of appropriate use of health care services, recording bias or true differences in provider management. Further analysis should involve larger and more complete data sets to explore ethnic differences in greater detail.
