Cost-effectiveness analysis of parenteral iron therapy compared to oral iron supplements in managing iron deficiency anemia among pregnant women

OBJECTIVE

This study compared the clinical efficacy and cost-effectiveness of parenteral iron, using intravenous iron sucrose (IVIS) therapy against the standard regimen of oral iron (OI) therapy for managing iron-deficiency anemia (IDA) among pregnant women in a natural primary care setting in Gujarat.

DESIGN

A prospective cost-effectiveness study was conducted in natural programme setting wherein 188 pregnant women in their 14 to 18 weeks with moderate and severe anemia women enrolled from two districts of Gujarat, and 142 were followed up until the post-partum phase. The intervention group comprised of 82 participants who were administered IVIS, while the comparison group comprised of 106 participants who were put on OI therapy. Hemoglobin (Hb) levels were measured at periodic intervals, first during enrollment and then during each month of pregnancy period and finally on the 42nd day of the post-natal period.

OUTCOME MEASURES

Change in mean Hb level from baseline was the primary outcome, while the incidence of morbidity and mortality was a secondary outcome measure.

RESULTS

The intervention group showed a significant incremental mean change in Hb level from 8.2 g/dl to 11.45 g/dl at the fourth follow-up, while the control group's mean Hb level reduced from 9.99 g/dl to 9.55 g/dl. The discounted cost per beneficiary for IVIS was US$ 87, while that for OI was US$ 49. The incremental cost-effectiveness ratio (ICER) was US$ 9.84, which is 0.049% of India's per capita GDP.

CONCLUSION

IVIS therapy was more clinically effective and cost-effective than OI therapy among pregnant women for management of moderate and severe anemia.

Clinical outcome post treatment of anemia in pregnancy with intravenous versus oral iron therapy: a systematic review and meta-analysis

Oral iron therapy is often the most common way of treating anaemia; however intravenous iron is considered effective due to rapid iron replenishment. We have dearth of evidence on clinical outcomes post treatment of anaemia. We have searched studies published in English in PubMed, Cochrane, Scopus, ProQuest, and Google Scholar. Our study analysed the clinical outcomes amongst neonates and mother and the adverse events post treatment and assessed the mean change in maternal haemoglobin concentration in both the groups. Forest plots for the clinical outcomes are presented. From a total of 370 studies, 34 Randomized and quasi experimental studies comparing clinical outcomes post-treatment of anaemia in pregnancy were included for quantitative evidence synthesis. Pooled results of maternal clinical outcomes using random effect model [OR: 0.79 (95% CI 0.66; 0.95); 10 outcomes; 17 studies] showed statistically significant difference among both the groups [Moderate quality evidence]; however no significant difference [OR: 0.99 (95% CI 0.86; 1.14); 7 outcomes; 8 studies] have been observed for neonatal complications [Low quality evidence]. The study found that pregnant women receiving IV iron were significantly less likely to experience adverse events as compared with those receiving oral iron [OR 0.39;  (95% CI 0.26-0.60)]; 34 studies; 13,909 women; [Low quality evidence]. Findings from meta-regression analysis showed that IV iron is more likely to reduce maternal complications by 21% compared to oral iron. Increase in odds of adverse maternal outcomes was observed due to increase in gestational age and publication year but no effect for the type of drug used. IV iron increases Hb more and at a higher pace than oral iron. Intravenous iron is more likely to avert adverse maternal outcomes and adverse reactions. However, there is no conclusive evidence on its effectiveness on individual maternal outcome or neonatal outcome/s. Protocol registered with PROSPERO CRD42022368346).

Protocol for the cost-effectiveness of parenteral iron and oral iron therapy for first-line management of anaemia among pregnant women in a natural programme setting in Gujarat

INTRODUCTION

Maternal anaemia is a major public health issue in India. The government of India recommends parenteral iron to manage moderate and severe grades of anaemia. In contrast to its clinical efficacy, the cost-effectiveness of intravenous iron sucrose and ferric carboxymaltose is not yet established in Indian context. This article illustrates the protocol of health technology assessment to evaluate the cost-effectiveness of intravenous therapy on the improvement of haemoglobin concentration over oral therapy.

METHODS AND ANALYSIS

The study will be carried out in two districts of Gujarat state. The study participants will be selected by a proportionate sampling method from the rural, tribal, desert and coastal region of the districts. Data will be collected over 1 year on key outcome indicators using a mixed-method approach. Key informant interviews will be conducted, and cost data will be gathered to perform cost-effectiveness analysis.

ETHICS AND DISSEMINATION

This study is approved by the Technical Appraisal Committee of Health Technology Assessment India, Department of Health Research and Institutional Ethics Committee of the Indian Institute of Public Health, Gandhinagar.

A comparative study to evaluate oral iron and intravenous iron sucrose for treatment of anemia in pregnancy in a poor socioeconomic region of Northeast India

Objective:

The prevalence of anemia during pregnancy is as high as 80% in some sections of the Indian population. Iron therapy in different forms has been found to alleviate anemia and yield good fetomaternal outcome. This study aims to evaluate the efficacy of intravenous iron sucrose (IVIS) versus oral iron in treating anemia among the antenatal mothers attending a tertiary care center of Northeast India.

Materials and Methods:

One hundred women between 18 and 28 weeks of gestation with diagnosed iron-deficiency anemia and hemoglobin (Hb) of 7–10.9 g/dL were enrolled to be administered either oral ferrous sulfate 200 mg twice daily or requisite dose of IVIS 100 mg in 100 ml normal saline on alternate days. Hb and hematocrit were measured at the time of enrollment, 4^th week, and 8^th week of therapy. Acceptability of both the drugs based on like and dislike after interviewing the study participants was recorded. Adverse drug reactions, gestational age at delivery, and neonatal birth weight were also noted in both the groups. The results were analyzed by Student's t-test and Chi-square test.

Results:

Hb and hematocrit values were found to be increased in both the groups at 4^th and 8^th weeks. When both the groups were compared, the rise in the values was higher in the iron sucrose group (at 4^th week P = 0.01 and at 8^th week P = 0.00). The number of participants who reached target Hb levels at 4 weeks was 41 (82%) with oral iron and 48 (96%) with iron sucrose. In the iron sucrose group, no adverse effects were observed, suggesting its safety, and the acceptability and newborn birth weight were noted to be higher.

Conclusion:

IVIS was found to be more effective than oral iron therapy in treating antenatal anemia with no serious adverse drug reactions.

Parenteral Versus Oral Iron for Treatment of Iron Deficiency Anaemia During Pregnancy and post-partum: A Systematic Review

Introduction

The burden of iron deficiency anaemia during pregnancy and post-partum continues to remain high especially in India. Challenges to treatment include gastrointestinal side effects and non compliance to oral iron therapy. Newer parenteral formulations need to be explored as alternatives.

Methods

Meta-analysis of randomized controlled trials published between years 2011 and 2018 comparing anaemic pregnant and post-partum women treated with intravenous iron sucrose versus oral iron was performed. The primary outcomes were mean maternal haemoglobin, serum ferritin and haematocrit at the end of 1st, 2nd, 4th and 6th weeks and comparison of adverse effects.

Results

Eighteen studies including 1633 antenatal women were randomly assigned to intravenous iron sucrose (n = 821) or oral iron [ferrous sulphate, ferrous ascorbate or fumarate] group (n = 812) in ten trials . Another eight studies compared iron sucrose infusion with oral iron in 713 post-partum women who were randomly assigned to intravenous iron sucrose group (n = 351) or oral iron group (n = 362). Cumulative analysis of all the time points indicates that the estimated mean values of Hb in the intravenous iron sucrose and oral iron groups were 10.11 g/dl and 9.33 g/dl, respectively, in antenatal group, while it was 10.57 g/dl and 9.74 g/dl in post-partum. The estimated mean ferritin level from first week to six weeks was 63.1 μg/l and 28.6 μg/l, respectively, in intravenous and oral iron groups. Cumulative estimate of haematocrit in the intravenous sucrose and oral iron over 6 weeks showed that the mean values in the respective groups were 30.5% and 29.5% in antenatal and 33.8% and 31.6%, respectively, in post-partum groups. Sensitivity analysis confirmed the reliability and consistency of the results. Oral iron was associated with significant gastrointestinal side effects. There was no significant difference in birthweight between the groups.

Conclusion

This meta-analysis demonstrates that intravenous iron sucrose is more effective than oral iron therapy for pregnant and post-partum women with iron deficiency anaemia. It is an effective and safe alternative to address the problem of iron deficiency especially in those who require rapid replacement of iron stores though medical personnel for intravenous administration of drug is required.Trial registration CRD42015024343.
