Randomized Controlled Trial Multicenter Study
Improving screening and brief intervention activities in primary health care: Secondary analysis of professional accuracy based on the AUDIT-C.
The ODHIN trial found that training and support and financial reimbursement increased the proportion of patients that were screened and given advice for their heavy drinking in primary health care. However, the impact of these strategies on professional accuracy in delivering screening and brief advice is underresearched and is the focus of this paper. ⋯ Although the use of AUDIT-C as a screening tool was accurate, a considerable proportion of risky drinkers did not receive advice, which was reduced with financial incentives.

Identifying causal mechanisms in health care interventions using classification tree analysis.
Mediation analysis identifies causal pathways by testing the relationships between the treatment, the outcome, and an intermediate variable that mediates the relationship between the treatment and outcome. This paper introduces classification tree analysis (CTA), a machine-learning procedure, as an alternative to conventional methods for analysing mediation effects. ⋯ CTA may uncover mediation effects where conventional approaches do not, because CTA does not require any assumptions about the distribution of variables nor of the functional form of the model, and CTA will systematically identify all statistically viable interactions. The versatility of CTA enables the investigator to explore the theorized underlying causal mechanism of an intervention in a much more comprehensive manner than conventional mediation analytic approaches.

Cost-effectiveness of the Family Nurse Partnership (FNP) programme in England: Evidence from the building blocks trial.
The Family Nurse Partnership (FNP) is a licensed intensive home visiting intervention developed in the United States. It has been provided in England by the Department of Health since 2006. The Building Blocks trial assessed the effectiveness and cost-effectiveness of FNP in England. ⋯ Given the absence of significant benefits of FNP in terms of the primary outcomes of the trial and only marginal maternal QALY gains, FNP does not represent a cost-effective intervention when compared with existing services already offered to young pregnant women.

Mailed outreach and facilitated test ordering to promote cholesterol screening in community health centers: A randomized trial.
Lipid screening is central to cardiovascular risk assessment. We sought to determine whether a simple mailed outreach message and facilitated test ordering increase cholesterol screening among federally qualified community health center patients with no recent cholesterol screening test performed. ⋯ This outreach intervention promoting cholesterol screening was ineffective. Interventions that attempt to minimize barriers to cholesterol screening on multiple fronts and that are more compelling to patients are needed.

Application of systems thinking: 12-month postintervention evaluation of a complex health system intervention in Zambia: the case of the BHOMA.
Strong health systems are said to be paramount to achieving effective and equitable health care. The World Health Organization has been advocating for using system-wide approaches such as 'systems thinking' to guide intervention design and evaluation. In this paper we report the system-wide effects of a complex health system intervention in Zambia known as Better Health Outcome through Mentorship and Assessment (BHOMA) that aimed to improve service quality. ⋯ We applied an innovative approach to evaluate a complex intervention in low-income settings, exploring empirically how systems thinking can be applied in the context of health system strengthening. Although the intervention had some positive outcomes by employing system-wide approaches, we also noted unintended consequences.
