Article Synopsis
  • There is a lack of global agreement on using high-intensity interval training (HIIT) for patients with coronary artery disease (CAD) in cardiac rehabilitation programs.
  • The study involved a randomized controlled trial with 382 patients comparing low-volume HIIT and moderate-intensity steady-state (MISS) exercise over 8 weeks, showing that HIIT significantly improved cardiorespiratory fitness more than MISS.
  • Results indicated that low-volume HIIT is a safe, effective alternative to traditional exercise methods in cardiac rehabilitation for improving fitness in stable CAD patients.

Background: Forty years from the seminal work of Welsh GP Julian Tudor Hart on the Inverse Care Law, inequalities in health and healthcare remain deeply embedded in Wales. There is a wider gap (over 17 years) in healthy life expectancy between people living in the most and least deprived neighborhoods in Wales. This health inequality is reflected in additional healthcare use.

Background: Reducing bullying is a public health priority. KiVa, a school-based anti-bullying programme, is effective in reducing bullying in Finland and requires rigorous testing in other countries, including the UK. This trial aims to test the effectiveness and cost-effectiveness of KiVa in reducing child reported bullying in UK schools compared to usual practice.

Background: Previous evidence suggests home-based dialysis to be more cost-effective than unit-based or hospital-based dialysis. However, previous analyses to quantify the costs of different dialysis modalities have used varied perspectives, different methods, and required assumptions due to lack of available data. The National Institute for Health and Care Excellence reports uncertainty about the differences in costs between home-based and unit-based dialysis.

Background: In the UK, there is evidence that girls' physical activity tends to decline to a greater extent than boys as they enter adolescence. 'Role models' could play a vital role in inspiring girls to become or remain physically active. The CHARMING Programme is a primary school-based community linked role-model programme, co-developed in 2016, with children, parents, schools and wider stakeholders.

Introduction: Kidney disease is common, affecting up to 1 in 10 of the adult population, and the numbers are expected to rise over the next decade. There are three main treatments that are available to patients with kidney disease: transplantation, dialysis and supportive care without dialysis. Dialysis can occur in a dialysis unit or in a person's home, but unit-based dialysis remains the most common initial treatment for patients in Wales.

Physical inactivity has been identified as a leading risk factor for premature mortality globally, and adolescents, in particular, have low physical activity levels. Schools have been identified as a setting to tackle physical inactivity. Economic evidence of school-based physical activity programmes is limited, and the costs of these programmes are not always collected in full.

Background: Previous systematic reviews have found that nurses and pharmacists can provide equivalent, or higher, quality of care for some tasks performed by GPs in primary care. There is a lack of economic evidence for this substitution.

Aim: To explore the costs and outcomes of role substitution between GPs and nurses, pharmacists, and allied health professionals in primary care.

Background: Exercise referral schemes (ERSs) are recommended for patients with health conditions or risk factors. Evidence points to the initial effectiveness and cost-effectiveness of such schemes for increasing physical activity, but effects often diminish over time. Techniques such as goal setting, self-monitoring, and personalized feedback may support motivation for physical activity and maintenance of effects.

Background: Health economic evaluations rely on the accurate measurement of health service resource use in order to calculate costs. These are usually measured with patient completed questionnaires using instruments such as the Client Service Receipt Inventory (CSRI). These rely on participants' recall and can be burdensome to complete.

Background: Unintended repeat conceptions can result in emotional, psychological and educational harm to young women, often with enduring implications for their life chances. This study aimed to identify which young women are at the greatest risk of repeat unintended pregnancies; which interventions are effective and cost-effective; and what are the barriers to and facilitators for the uptake of these interventions.

Methods: We conducted a mixed-methods systematic review which included meta-analysis, framework synthesis and application of realist principles, with stakeholder input and service user feedback to address this.

Introduction: Children with autistic spectrum disorder (ASD) often have associated behavioural difficulties that can present a challenge for parents and parenting. There are several effective social learning theory-based parenting programmes for dealing with behavioural difficulties, including the Incredible Years (IY) parent programmes. However, these programmes typically do not specifically target parents of children with ASD.

Background: Previous research has demonstrated emotional, psychological and educational harm to young mothers following unintended conceptions. The UK has one of the highest rates of pregnancies in adolescence in Western Europe with a high proportion of these being repeat pregnancies, making it a topic of interest for public health policy makers, and health and social care practitioners. As part of a wider mixed-methods systematic review, realist principles were applied to synthesise evidence about interventions aiming to reduce repeat pregnancies in adolescence.

Background: Wales faces serious public health challenges, with relatively low life expectancies and wide inequalities in life expectancy with associated pressures on the National Health Service (NHS) at a time of financial recession. This has led to growing recognition of the need to better understand the range of health improvement and prevention programmes across Welsh Government, NHS, local government and voluntary sector agencies.

Methods: The Minister for Health and Social Care commissioned Public Health Wales, the single national public health organisation, to establish a Health Improvement Advisory Group, to oversee a Programme Budgeting and Marginal Analysis (PBMA) expert panel.
