Setting: Tuberculosis (TB) health facilities in the Republic of Moldova, where various incentives were provided to TB patients to improve treatment outcomes.

Objective: To compare treatment outcomes among new drug-susceptible TB patients registered for treatment before (2008) and after (2011) introduction of incentives.

Design: Retrospective cohort study using data from the national electronic patient database and incentive registers.

Results: Of 2378 patients registered in 2011, 1895 (80%) received incentives (cash, food vouchers, travel reimbursement). Compared to 2008 (no incentives, n = 2492), the patients registered with incentives in 2011 had higher treatment success (88% vs. 79%, P < 0.001) and lower proportions of unsuccessful outcomes: loss to follow-up (5% vs. 10%, P < 0.001), death (5% vs. 6%, P = 0.03) and failure (2% vs. 5%, P < 0.001). In multivariate analysis (log-binomial regression) using the intention-to-treat approach, provision of incentives was independently associated with an overall reduction in unsuccessful outcomes of 50% (RR 0.5, 95%CI 0.45-0.62, P < 0.001), after adjusting for other confounders such as sex, age, education, occupation, residence, homelessness, type of TB and human immunodeficiency virus status.

Conclusion: Provision of incentives to TB patients significantly improved treatment success rates and needs to continue. Treatment retention increased, thus potentially preventing drug resistance, a serious problem in the Republic of Moldova.

Background: Heart failure (HF) is a chronic, progressive condition where the heart cannot pump enough blood to meet the body's needs. In addition to the daily challenges that HF poses, acute exacerbations can lead to costly hospitalizations and increased mortality. High health care costs and the burden of HF have led to the emerging application of new technologies to support people living with HF to stay well while living in the community.

Background: Diabetes affects half of the patients with cystic fibrosis who are aged 30 years and older. Diabetes progresses asymptomatically over a long period of time. Two treatment options are possible: start insulin as soon as cystic fibrosis diagnosis is made with the additional constraints of cystic fibrosis or wait while monitoring the patient's clinical condition and start insulin when diabetes symptoms develop and therefore later.

Introduction: High-Flow Nasal Therapy (HFNT) is an innovative non-invasive form of respiratory support. Compared to standard oxygen therapy (SOT), there is an equipoise regarding the effect of HFNT on patient-centred outcomes among those at high risk of developing postoperative pulmonary complications after undergoing cardiac surgery. The NOTACS trial aims to determine the clinical and cost-effectiveness of HFNT compared to SOT within 90 days of surgery in the United Kingdom, Australia, and New Zealand.
