The cost-effectiveness of tranexamic acid for treatment of postpartum hemorrhage: A systematic review.

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.

Project description:BackgroundNewer research comparing routes of medication administration has extended beyond efficacy as a primary endpoint to incorporate patient preference. However, little is known about the preferences of pregnant women in terms of routes of medication administration, specifically with regards to hemorrhage prevention and control.ObjectiveThis study aimed to understand the preferences of pregnant women in terms of medical interventions to prevent hemorrhage at the time of delivery.Study designSurveys were distributed from April 2022 to September 2022 using electronic tablets at a single urban center with an annual delivery volume of 3000 women per year to women >18 years of age who were either currently pregnant or have been pregnant in the past. Subjects were asked to choose their preferred route of administration from the following options: intravenous, intramuscular, or subcutaneous. The primary outcome was patient preference on the route of medication administration during a hemorrhage event.ResultsThe study cohort included 300 patients, mostly African American (39.8%) followed by White (32.1%), and the majority of the participants ranged from 30 to 34 years of age (31.7%). When asked which method of administration they would prefer to prevent hemorrhage before birth, the results were as follows: 31.1% would prefer intravenous, 23.0% had no preference, 21.2% were unsure, 15.9% preferred subcutaneous, and 8.8% preferred intramuscular administration. In addition, 69.4% of respondents reported that they have never declined or avoided intramuscular administration of medication if recommended by their physician.ConclusionAlthough some survey participants preferred an intravenous route of administration, 68.9% of subjects were unsure, had no preference, or preferred nonintravenous routes. This information is helpful particularly in low-resource settings where intravenous treatments are not readily available or in urgent clinical situations in which intravenous administration routes are not easily obtainable in high-risk patients.

Project description:BackgroundOral tranexamic acid (TXA), if effective in reducing blood loss after delivery for women experiencing primary PPH, could be administered where parenteral administration is not feasible. This trial assessed the efficacy, safety, and acceptability of oral TXA when used as an adjunct to sublingual misoprostol to treat postpartum hemorrhage (PPH) following vaginal delivery.MethodsFrom October 2016 to January 2018, women presenting at four hospitals in Senegal and Vietnam for vaginal delivery were screened for enrollment in the trial. Women diagnosed with postpartum hemorrhage (defined as blood loss ≥700 ml) were randomized to receive either oral TXA (1950 mg) or placebo in addition to 800 mcg sublingual misoprostol. Postpartum blood loss was measured using a calibrated drape. Blood loss for all PPH cases was recorded for 2 h after administration of the drugs. The primary outcome measure was the proportion of women with bleeding controlled with the trial regimen without recourse to further treatment. Secondary outcomes including the rate of severe PPH, mean/median blood loss, use of additional uterotonics and/or interventions side effects, and acceptability were also recorded.ResultsOf the 258 women who received treatment for PPH, 128 received placebo and misoprostol and 130 received TXA and misoprostol. The proportion of women who had active bleeding controlled with trial drugs alone and no additional interventions was similar in both groups: 77(60.2%) placebo; 74 (56.9%) TXA, p = 0.59). Use of other interventions to control bleeding, including uterotonics, did not differ significantly between groups. Median blood loss at PPH diagnosis was 700 ml in both groups. Uterine atony alone or in addition to another cause contributed to over 90% of PPH cases reported (92.2% placebo vs. 91.5% TXA), other causes included perineal and cervical lacerations and retained placenta. Reports of side effects and acceptability were similar in the two groups.ConclusionAdjunct use of oral TXA with misoprostol to treat PPH resulted in similar clinical and acceptability outcomes when compared to treatment with misoprostol alone.Trial registrationThis trial was registered with ClinicalTrials.gov, number NCT02805426. Registered on 3 September 2016.

Project description:BackgroundPostpartum hemorrhage (PPH) is the global leading cause of maternal mortality, affecting nearly 3 to 6 percent of all women giving birth in India. The World Health Organization (WHO) has updated its guidelines to recommend the early use of intravenous (IV) tranexamic acid (TXA) in addition to standard care for all diagnosed PPH cases. This study aimed to assess the cost-effectiveness of introducing TXA for PPH management in the Indian public health system.MethodsA decision analytic model was built using a decision tree to determine the cost-effectiveness of administering IV TXA to women experiencing PPH within 3 h of birth to existing management with uterotonics and supportive care. Using a disaggregated societal perspective, the costs and consequences for a hypothetical cohort of women experiencing PPH in public health facilities was estimated. The model was populated using probabilities, clinical parameters, and utilities from published literature, while cost parameters were largely derived from a primary economic costing study. The primary outcome of interest was the incremental cost-utility ratio (ICUR). Associated clinical events and net benefits were estimated. One-way and probabilistic sensitivity analysis (PSA) was undertaken. The budget impact was estimated for a national-level introduction.ResultsFor an estimated annual cohort of 510,915 PPH cases in India, the addition of IV TXA would result in a per-patient disaggregated societal cost of INR 6607 (USD 95.15) with a discounted gain of 20.25 QALYs, as compared to a cost of INR 6486 (USD 93.41) with a discounted gain of 20.17 QALYs with standard care PPH management. At an ICUR value of INR 1470 per QALY gained (USD 21), the addition of IV TXA is cost-effective in Indian public health settings. The intervention is likely to prevent 389 maternal deaths, 177 surgeries, and 128 ICU admissions per 100,000 PPH cases. The findings are robust under uncertainty, with 94.5% of PSA simulations remaining cost-effective. A cumulative increase of 2.3% financial allocation for PPH management over five years will be incurred for TXA introduction.ConclusionsAddition of tranexamic acid for primary PPH management, as recommended by WHO, is cost-effective in Indian public health settings. Policy guidelines, training manuals, and facility checklists should be updated to reflect this recommendation.
