National or population level interventions addressing the social determinants of mental health - an umbrella review.

BACKGROUND: Social circumstances in which people live and work impact the population's mental health. We aimed to synthesise evidence identifying effective interventions and policies that influence the social determinants of mental health at national or scaled population level. We searched five databases (Cochrane Library, Global Health, MEDLINE, EMBASE and PsycINFO) between Jan 1st 2000 and July 23rd 2019 to identify systematic reviews of population-level interventions or policies addressing a recognised social determinant of mental health and collected mental health outcomes. There were no restrictions on country, sub-population or age. A narrative overview of results is provided. Quality assessment was conducted using Assessment of Multiple Systematic Reviews (AMSTAR 2). This study was registered on PROSPERO (CRD42019140198). RESULTS: We identified 20 reviews for inclusion. Most reviews were of low or critically low quality. Primary studies were mostly observational and from higher income settings. Higher quality evidence indicates more generous welfare benefits may reduce socioeconomic inequalities in mental health outcomes. Lower quality evidence suggests unemployment insurance, warm housing interventions, neighbourhood renewal, paid parental leave, gender equality policies, community-based parenting programmes, and less restrictive migration policies are associated with improved mental health outcomes. Low quality evidence suggests restriction of access to lethal means and multi-component suicide prevention programmes are associated with reduced suicide risk. CONCLUSION: This umbrella review has identified a small and overall low-quality evidence base for population level interventions addressing the social determinants of mental health. There are significant gaps in the evidence base for key policy areas, which limit ability of national policymakers to understand how to effectively improve population mental health.

Developing a nurse-led salbutamol weaning pathway for children and young people with asthma or viral-induced wheeze.

Acute asthma exacerbations and viral-induced wheeze are common presenting complaints on one general paediatric ward in a tertiary children's hospital in England. An inhaled beta 2 agonist, such as salbutamol, is the first-line treatment for these children and young people and they have frequent clinician reviews for salbutamol weaning before discharge. However, the informal salbutamol weaning practices used by nurses, as well as challenges in the recruitment and retention of paediatric trainee doctors, led to the development of a nurse-led salbutamol weaning pathway as a quality improvement project. Twelve nurses completed the associated nurse-led salbutamol weaning training, education and competency package and subsequently completed a questionnaire exploring their perceptions of the effect of the training package and pathway. After the training, all respondents reported feeling more confident in assessing the salbutamol requirements of children with wheeze. All of the respondents also felt that the introduction of the pathway and training would improve patient care and the confidence of children and young people, parents and carers in nurses' ability to assess children's salbutamol requirements. Time constraints were identified as a potential barrier to implementation of the pathway.
