Patient Safety Events Among People from Ethnic Minority Backgrounds: A Retrospective Medical Record Review of Australian Cancer Services.

Objectives: People from ethnic minority backgrounds are exposed to greater risk of patient safety events (such as healthcare-acquired infections and medication errors) occurring in their healthcare. However, evidence of the type and frequency of patient safety events occurring in cancer care among patients from ethnic minority background is lacking. This study sought to address this evidence gap.

Design: A two-stage retrospective medical record review was conducted at four cancer services in two Australian states. Eligible medical records at each service that were identified as belonging to ethnic minority patients were reviewed by two clinician researchers in stage one, followed by authentication of extracted data by a site-specific cancer clinician in stage two. Descriptive statistics were used to report the frequency and type of safety events. Chi-square and independent sample T-tests were used to examine the association between safety events and patient socio-cultural indicators.

Results: A total of 628 patient records were included. Of the 628 patient records, 212 (33.75%) documented at least one safety event. A total of 410 safety events were documented in the 212 patient records. Medication-related safety events were most commonly documented (121/410, 29.5%), followed by clinical process/procedure-related safety events (76/410, 18.5%) and patient accidents (60/410, 14.6%). The occurrence of a safety event was associated with patient records that documented 'no interpreter was required'.

Conclusion: Patient safety events in cancer care occur frequently among patients from ethnic minority backgrounds. Unsafe cancer care for this population is associated with inadequate use of interpreters, lack of shared understanding and expectations of care processes linked to cultural and linguistic barriers. Approaches to enhance engagement are required.
