BACKGROUND Pay-for-performance programs are being adopted internationally despite little evidence that they improve patient outcomes. In 2008, a program called Advancing Quality, based on the Hospital Quality Incentive Demonstration in the United States, was introduced in all National Health Service (NHS) hospitals in the northwest region of England(More)
Gender is a critical component of HIV and sexual risk interventions. Examining the range, effectiveness and methodological rigor of studies that include a gender based component can inform current interventions and future directions for intervention research. This review investigated gender informed intervention studies conducted in sub-Saharan Africa that(More)
This paper examines the synthetic control method in contrast to commonly used difference-in-differences (DiD) estimation, in the context of a re-evaluation of a pay-for-performance (P4P) initiative, the Advancing Quality scheme. The synthetic control method aims to estimate treatment effects by constructing a weighted combination of control units, which(More)
Reducing waiting times has been a major focus of the English National Health Service for many years, but little is known about the impact on health outcomes. The collection of data on patient-reported outcome measures for all patients undergoing four large-volume procedures facilitates analysis of the impact of waiting times on patient outcomes. The(More)
BACKGROUND Mechanical chest compression devices may help to maintain high-quality cardiopulmonary resuscitation (CPR), but little evidence exists for their effectiveness. We evaluated whether or not the introduction of Lund University Cardiopulmonary Assistance System-2 (LUCAS-2; Jolife AB, Lund, Sweden) mechanical CPR into front-line emergency response(More)
BACKGROUND In low and high income countries alike, disability exacerbates social, economic, and health disparities, in spite of their differences. OBJECTIVE This study seeks to identify factors that predict the circumstances people with disabilities face, including poverty. METHODS A cross-sectional study design was employed using census track level(More)
AIM To assess the cost-effectiveness of LUCAS-2, a mechanical device for cardiopulmonary resuscitation (CPR) as compared to manual chest compressions in adults with non-traumatic, out-of-hospital cardiac arrest. METHODS We analysed patient-level data from a large, pragmatic, multi-centre trial linked to administrative secondary care data from the Hospital(More)
Gender is a critical concept of human immunodeficiency virus (HIV) sexual risk; yet, few studies have examined the intersection between risk and protective factors associated with incidence of HIV among couples. The paper examines gender-specific constructs of resiliency among couples in Kenya. Using data from the Demographic and Health Surveys, Kenya(More)
BACKGROUND Within the United States, public insurance premiums are used both to discourage private health policy holders from dropping coverage and to reduce state budget costs. Prior research suggests that the odds of having private coverage and being uninsured increase with increases in public insurance premiums. The aim of this paper is to test effects(More)
Older people who live alone are a growing, high-cost group for health and social services. The literature on how living alone affects health and the costs and benefits of healthcare has focused on crude measures of health and utilisation and gives little consideration to other cost determinants and aspects of patient experience. We study the effect of(More)
