Improving cultural competence of healthcare workers in First Nations communities: a narrative review of implemented educational interventions in 2015-20.

BACKGROUND: Cultural competency is often promoted as a strategy to address health inequities; however, there is little evidence linking cultural competency with improved patient outcomes. This article describes the characteristics of recent educational interventions designed to improve cultural competency in healthcare workers for First Nations peoples of Australia, New Zealand, Canada and the USA. METHODS: In total, 13 electronic databases and 14 websites for the period from January 2015 to May 2021 were searched. Information on the characteristics and methodological quality of included studies was extracted using standardised assessment tools. RESULTS: Thirteen published evaluations were identified; 10 for Australian Aboriginal and Torres Strait Islander peoples. The main positive outcomes reported were improvements in health professionals' attitudes and knowledge, and improved confidence in working with First Nations patients. The methodological quality of evaluations and the reporting of methodological criteria were moderate. CONCLUSIONS: Cultural competency education programs can improve knowledge, attitudes and confidence of healthcare workers to improve the health of First Nations peoples. Providing culturally safe health care should be routine practice, particularly in places where there are concentrations of First Nations peoples, yet there is relatively little research in this area. There remains limited evidence of the effectiveness of cultural education programs alone on community or patient outcomes.

Relations among heart failure severity, left ventricular loading conditions, and repolarization length in advanced heart failure secondary to ischemic or idiopathic dilated cardiomyopathy.

In patients with heart failure (HF), low peak oxygen consumption (VO(2)) and prolonged QT interval or enhanced QT variability are associated with poor prognosis. Whether HF severity or left ventricular (LV) loading conditions can influence repolarization length is unknown. Survival, QTc interval, peak VO(2), clinical, laboratory, echocardiographic, and invasive hemodynamic data were analyzed in 154 transplant candidates; mortality was examined after a mean follow-up of 4.3 +/- 1.8 years. The relation between the QTc interval and other variables was examined using multivariate analysis and multiple correlation coefficients. Patients were stratified by peak VO(2) to study its relation with peak VO(2), mortality, loading conditions, and QTc intervals. Mean ejection fraction was 10 +/- 9%; mean cardiac index was 2.06 +/- 0.7 L/min/m(2). Seventy-one patients (47%) were dead at the end of study. Mortality and nonfatal ventricular arrythmias were higher (p <0.01) in patients with lower peak VO(2) and longer QTc intervals (p <0.001). An inverse correlation was found between QTc interval length and peak VO(2) (r = -0.790, p <0.0001). No correlation was found between QTc interval and LV loading conditions or the other analyzed variables. Thus, repolarization length measured by the QTc interval is inversely correlated with HF severity measured by peak VO(2) and is independent of LV loading conditions in patients with severe HF.
