Competency requirements for middle and senior managers in community health services.

The Australian health system has been subjected to rapid changes in the last 20 years to meet increasingly unmet health needs. Improvement of the efficiency and comprehensiveness of community-based services is one of the solutions to reducing the increasing demand for hospital care. Competent managers are one of the key contributors to effective and efficient health service delivery. However, the understanding of what makes a competent manager, especially in the community health services (CHS), is limited. Using an exploratory and mixed-methods approach, including focus group discussions and an online survey, this study identified five key competencies required by senior and mid-level CHS managers in metropolitan, regional and rural areas of Victoria: Interpersonal, communication qualities and relationship management; Operations, administration and resource management; Knowledge of the health care environment; Leading and managing change; and Evidence-informed decision-making. This study confirms that core competencies do exist across different management levels and improves our understanding of managerial competency requirements for middle to senior CHS managers, with implications for current and future health service management workforce development.

Air pollution, ethnicity and telomere length in east London schoolchildren: An observational study.

BACKGROUND: Short telomeres are associated with chronic disease and early mortality. Recent studies in adults suggest an association between telomere length and exposure to particulate matter, and that ethnicity may modify the relationship. However associations in children are unknown. OBJECTIVES: We examined associations between air pollution and telomere length in an ethnically diverse group of children exposed to high levels of traffic derived pollutants, particularly diesel exhaust, and to environmental tobacco smoke. METHODS: Oral DNA from 333 children (8-9years) participating in a study on air quality and respiratory health in 23 inner city London schools was analysed for relative telomere length using monochrome multiplex qPCR. Annual, weekly and daily exposures to nitrogen oxides and particulate matter were obtained from urban dispersion models (2008-10) and tobacco smoke by urinary cotinine. Ethnicity was assessed by self-report and continental ancestry by analysis of 28 random genomic markers. We used linear mixed effects models to examine associations with telomere length. RESULTS: Telomere length increased with increasing annual exposure to NOx (model coefficient 0.003, [0.001, 0.005], p<0.001), NO2 (0.009 [0.004, 0.015], p<0.001), PM2.5 (0.041, [0.020, 0.063], p<0.001) and PM10 (0.096, [0.044, 0.149], p<0.001). There was no association with environmental tobacco smoke. Telomere length was increased in children reporting black ethnicity (22% [95% CI 10%, 36%], p<0.001) CONCLUSIONS: Pollution exposure is associated with longer telomeres in children and genetic ancestry is an important determinant of telomere length. Further studies should investigate both short and long-term associations between pollutant exposure and telomeres in childhood and assess underlying mechanisms.
