Abstract
BACKGROUND AND OBJECTIVES Pre-donation screening of potential blood donors is critical for ensuring the safety of the donor blood supply, and donor deferral as a result of risk factors is practised worldwide. This systematic review was conducted in the context of an expert review convened by the Australian Red Cross Lifeblood in 2013 to consider Lifeblood's injecting drug use (IDU)-related policies and aimed to identify studies assessing interventions to improve compliance with deferral criteria in blood donation settings. MATERIALS AND METHODS MEDLINE/PubMed, OVID Medline, OVID Embase, LILACS, and the Cochrane Library (CENTRAL and DARE) databases were searched for studies conducted within blood donation settings that examined interventions to increase blood donor compliance with deferral criteria. Observational and experimental studies from all geographical areas were considered. RESULTS Ten studies were identified that tested at least one intervention to improve blood donor compliance with deferral criteria, including computerized interviews or questionnaires, direct and indirect oral questioning, educational materials, and a combination of a tickbox questionnaire and a personal donor interview. High-quality evidence from a single study was provided for the effectiveness of a computerized interview in improving detection of HIV risk behaviour. Low-quality evidence for the effectiveness of computerized interviews was provided by 3 additional studies. Two studies reported a moderate effect of direct questioning in increasing donor deferral, but the quality of the evidence was low. CONCLUSION This review identified several interventions to improve donor compliance that have been tested in blood donation settings and provided evidence for the effectiveness of computerized interviews in improving detection of risk factors.

Abstract
BACKGROUND Postpartum hemorrhage (PPH) is responsible for nearly one quarter of maternal deaths. A 2017 multicountry trial found that incorporating tranexamic acid (TXA) into the PPH management package was effective in reducing maternal death due to bleeding. OBJECTIVE To systematically review studies assessing the cost-effectiveness of tranexamic acid for PPH treatment. SEARCH STRATEGY Nine databases were searched using variations of keywords 'tranexamic acid', 'postpartum hemorrhage' and 'cost effectiveness'. SELECTION CRITERIA Eligible studies were any type of economic or effectiveness evaluation studies on tranexamic acid for treating women with PPH. DATA COLLECTION AND ANALYSIS Two reviewers independently screened citations and extracted data on cost effectiveness measures. Quality was assessed using the Consensus on Health Economic Criteria list. MAIN RESULTS Four studies were included, of which two were abstracts. Three studies concluded that early administration of TXA was cost-saving or cost-effective. One abstract reported TXA was not cost-effective in the USA unless the probability of death due to hemorrhage is higher. CONCLUSION Available evidence (four studies in three countries) suggests that this life-saving intervention may be below willingness to pay thresholds (cost-effective) or cost saving. Further studies conducted in different populations and settings are needed to inform health policy decision-making to reduce PPH-associated morbidity and mortality.
PICO Summary
Population
Women with post-partum haemorrhage (PPH), (4 studies).
Intervention
Systematic review assessing the cost-effectiveness of tranexamic acid (TXA) for PPH treatment.
Comparison
Outcome
Three studies concluded that early administration of TXA was cost-saving or cost-effective. One abstract reported TXA was not cost-effective in the USA unless the probability of death due to haemorrhage was higher.

Abstract
BACKGROUND Uterine tamponade is widely promoted for treating refractory postpartum haemorrhage (PPH), however its cost-effectiveness may vary depending on unit costs and setting. OBJECTIVE To review available data on cost-effectiveness of uterine tamponade devices when used for PPH treatment. SEARCH STRATEGY PubMed and EMBASE were searched (1980 to January 2020), as well as the National Health Services Economic Evaluation database from inception (1995) to March 2015. SELECTION CRITERIA Eligible studies were any type of economic evaluation, or effectiveness studies that provided cost or economic data. DATA COLLECTION AND ANALYSIS Two reviewers independently screened studies, extracted data and assessed quality. MAIN RESULTS Eleven studies using a range of devices (condom catheter, uterine suction devices, Bakri, Inpress, Ellavi) were identified. Cost of condom catheter devices or kits ranged from US$0.64 to US$6, while purpose-designed devices were up to US$400. Two studies that took a health system perspective assessed cost-effectiveness of using uterine balloon tamponade and suggested it was highly cost-effective due to low cost per disability-adjusted life years (DALY) averted, though both used effect estimates from case series. CONCLUSIONS Evidence on the cost-effectiveness of uterine tamponade devices was limited and not generalizable. Rigorous economic evaluations based on updated effect estimates are needed.
