REVIEW
Ralf Jäger, Neeltje van den Berg, Falk Schwendicke
BACKGROUND: A spatially unequal distribution of dentists or dental care professionals (D/DCPs), such as therapists or hygienists, could reduce the quality of health services and increase health inequities. This review describes the interventions available to enhance this spatial distribution and systematically assesses their effectiveness. METHODS: Electronic databases (Cochrane CENTRAL, Medline, Embase, CINAHL) were searched and cross-referencing was performed using a standardised searching algorithm...

Uber, the world's largest ridesharing company, has reportedly provided over two billion journeys globally since operations began in 2010; however, the impact on motor vehicle crashes is unclear. Theoretically, ridesharing could reduce alcohol-involved crashes in locations where other modes of transportation are less attractive than driving one's own vehicle while alcohol-affected. We conducted interrupted time series analyses using weekly counts of injury crashes and the proportion that were alcohol-involved in four US cities (Las Vegas, NV; Portland, OR; Reno, NV; San Antonio, TX)...

BACKGROUND: In the third quarter of 2008, a major financial crisis hit many developed countries. Taiwan suffered its own share: a rise in unemployment and a severe decline in gross domestic product. This study is to address the health consequences of this crisis on different socioeconomic populations in Taiwan. METHODS: A sample of 6,225,766 men and 5,417,651 women, was obtained and their admissions data over 2007-2012 were retrieved. Stratified into three income levels, the sample was examined on the 147,921 episodes of hospitalization due to depressive illnesses (DIs) over that period by an interrupted time series analysis for monthly incidence rates of DI hospitalizations RESULTS: The adjusted incidence rates of hospitalization (AIRH) for DIs among the low income were 10 times that of the high income group...

PURPOSE: Research suggests that the Great Recession of 2007-2009 led to nearly 5000 excess suicides in the United States. However, prior work has not accounted for seasonal patterning and unique suicide trends by age and gender. METHODS: We calculated monthly suicide rates from 1999 to 2013 for men and women aged 15 and above. Suicide rates before the Great Recession were used to predict the rate during and after the Great Recession. Death rates for each age-gender group were modeled using Poisson regression with robust variance, accounting for seasonal and nonlinear suicide trajectories...

BACKGROUND: Smoke-free policies are important to protect health and reduce health inequalities. A major barrier to policy implementation in psychiatric hospitals is staff concern that physical violence will increase. We aimed to assess the effect of implementing a comprehensive smoke-free policy on rates of physical assaults in a large UK mental health organisation. METHODS: We did an interrupted time series analysis of incident reports of physical assault 30 months before and 12 months after the implementation of the policy in the inpatient wards of South London and Maudsley National Health Service Foundation Trust, London, UK...

INTRODUCTION: The worldwide prevalence of overweight/obesity has continued to rise over the last decades. To reverse this trend, public health authorities are exploring cost-effective interventions, especially in high-income and middle-income countries. Community gardening offers a unique opportunity for individuals to enhance physical activity levels and improve their diet. However, synthesised evidence on the short-term or long-term effectiveness and on the costs of community gardening interventions to prevent overweight/obesity remains limited...

BACKGROUND AND AIMS: In April 2015, the UK government enacted a temporary class drug order (TCDO) on ethylphenidate in response to reported harms associated with its use, in particular an outbreak of infections among people who inject drugs (PWID) in Lothian, Scotland. This study assesses the effect that the TCDO had on reducing the most common infections identified during the outbreak; Streptococcus pyogenes (S. pyogenes) and Staphylococcus aureus (S. aureus). DESIGN: The outbreak was split into a pre-intervention period (35 weeks) and a post-intervention period (26 weeks) based around the date of the TCDO...

Few studies have reported the effect of 10-valent pneumococcal conjugate vaccine (PCV10) on otitis media (OM) in infants. In particular, no population-based study in upper-middle income countries is available. In 2010, Brazil introduced PCV10 into its routine National Immunization Program using a 3+1 schedule. We measured the impact of PCV10 on all-cause OM in children. An interrupted time-series analysis was conducted in Goiânia/Brazil considering monthly rates (per 100,000) of all-cause OM outpatient visits in children aged 2-23 months...

Payments to users and providers of health services are an important ingredient in attempts to promote universal health coverage in low resource settings. The maternal health programme in Nepal explicitly recognizes that ensuring universal access to safe delivery care requires policies that both ensure effective services and overcome demand-side barriers. The programme has used three innovative financing initiatives to stimulate an increase in the use of facility-based delivery: the maternity incentive scheme (2005) reimbursing women for accessing a facility, activity payments in poor districts (2006) and universal free-delivery (2009)...
