Cost-effectiveness of hysterectomy, first- and second-generation endometrial ablation, and levonorgestrel-releasing device for treatment of heavy menstrual bleeding: a systematic review. Expert Rev Pharmacoecon Outcomes Res 2025; 25:155-171. [PMID: 39394931 DOI: 10.1080/14737167.2024.2417014] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/25/2024] [Revised: 09/17/2024] [Accepted: 10/11/2024] [Indexed: 10/14/2024]
Abstract
OBJECTIVES This study aims to provide a clear understanding of the relative economic evaluation of hysterectomy, first- and second-generation endometrial ablation, and levonorgestrel-releasing intrauterine device for treatment of heavy menstrual bleeding. METHODS A comprehensive search was conducted without restrictions until October 5, 2023, across databases including PubMed, EMBASE, Scopus, Cochrane, and others. The review included studies using full economic evaluation methods to compare treatments, excluding review articles, editorials, abstracts, and non-English articles. Methodological quality of included studies was assessed using the QHES checklist and analyzed with Incremental Cost-Effectiveness Ratios. RESULTS Out of 156 articles assessed for full-text evaluations, 23 publications were selected for qualitative analysis. Two studies deemed to be of low quality were excluded from the final analysis, while the majority of studies showcased high quality. The findings presented diverse perspectives on the most cost-effective treatment, with LNG-IUD frequently emerging as the preferred choice. CONCLUSION There are diverse methodologies in economic evaluations, impacting reported health economic outcomes due to varying perspectives, time horizons, and modeling approaches. The review highlighted the need for further research to establish optimal HMB treatment strategies and to guide healthcare resource allocation. REGISTRATION PROSPERO (CRD42024530176).

Abstract
OBJECTIVE To provide French guidelines for the management of women with abnormal uterine bleeding (AUB). DESIGN A consensus committee of 26 experts was formed. A formal conflict-of-interest policy was developed at the beginning of the process and enforced throughout. The entire guidelines process was conducted independently of any industry funding (i.e. pharmaceutical or medical device companies). The authors were advised to follow the rules of the Grading of Recommendations Assessment, Development and Evaluation (GRADE®) system to guide assessment of quality of evidence. The potential drawbacks of making strong recommendations in the presence of low-quality evidence were emphasized. METHODS The last guidelines from the Collège National des Gynécologues et Obstétriciens Français on the management of women with AUB were published in 2008. The literature seems now sufficient for an update. The committee studied questions within 7 fields (diagnosis; adolescents; idiopathic AUB; endometrial hyperplasia and polyps; type 0-2 fibroids; type 3 or higher fibroids; and adenomyosis). Each question was formulated in a PICO (Patients, Intervention, Comparison, Outcome) format and evidence profiles were compiled. The GRADE® methodology was applied to the literature review and the formulation of recommendations. RESULTS The experts' synthesis work and the application of the GRADE method resulted in 36 recommendations. Among the formalized recommendations, 19 are strong and 17 weak. No response was found in the literature for 14 questions. We chose to abstain from recommendations rather than providing advice based solely on expert clinical experience. CONCLUSIONS The 36 recommendations make it possible to specify the diagnostic and therapeutic strategies for various clinical situations practitioners encounter, from the simplest to the most complex.

Abstract
OBJECTIVE The objective of the study was to analyse the pregnancy rate after curettage, 1G (Endometrial resection) and 2G (Endometrial ablation) procedures in women with abnormal uterine bleeding (AUB-O,E,N) to evaluate the rate of pregnancy following these procedures and to improve pre and post-therapeutic women information. METHODS This retrospective study analyzed data extracted from the French Hospital medical information database. All hospital stays with a diagnostic code for AUB and an appropriate surgical procedure coded between 2009 and 2015 were identified. A total of 109,884 women were included. Of these, 88,165 were followed up for 18 months, 80,054 for 24 months and 33,251 for 60 months. Outcomes were compared between second generation (2G) procedures, first-generation (1G) procedures (endometrial resection) and curettage. The rate of pregnancy was the primary end point. RESULTS 7863 women underwent a 2G surgical procedure (7.2%), 39,935 a 1G procedure (36.3%) and 38,923 a curettage (35.4%). The mean age of the women was 46 years (IC.95: 36.7-52.5), with no difference in age between groups. The rate of pregnancy after 2G, 1G and curettage was respectively 13 (1.5%), 617 (10.1%) and 1025 (11.1%). The primary endpoint was significantly different between 2G and 1G and curettage (p<0.0001) CONCLUSION: 2G procedures result in lower risk of pregnancy without requiring specific training for surgeons. However, endometrial ablation cannot be considered as a sterilization method nor an effective contraceptive procedure. In the absence of sterilization of either partner, women should continue to use contraception whatever their age and menstrual status.

[PMID: 34653258 PMCID: PMC9540028 DOI: 10.1002/ijgo.13983] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/26/2021] [Revised: 10/07/2021] [Accepted: 10/14/2021] [Indexed: 11/06/2022]
Abstract
OBJECTIVE To evaluate the efficiency, postoperative hysterectomy rate, and influencing factors for therapeutic effect of the NovaSure endometrial ablation procedure in abnormal uterine bleeding (AUB). METHODS We conducted a retrospective cohort study of 2152 patients from the Department of Gynecology at the Third Xiangya Hospital, CSU from October 2010 to December 2018. RESULTS From the first year to the eighth year after operation, annual effective rate was above 95.24%, and the differences were not statistically significant. There are statistically significant differences between the effective and ineffective groups with regard to age, intrauterine polyps, total length of the uterus, systemic coagulation disorder, and preoperative hemoglobin. A multivariate logistic regression analysis showed that the risk factors associated with systemic coagulation disorders (P = 0.027) and high total uterine length (P = 0.003) affected NovaSure efficacy in the treatment of AUB. By December 2019, the postoperative hysterectomy rate was 1.86% (40/2152) and the complication rate was 1.67% (36/2152). CONCLUSION NovaSure is a reliable treatment for AUB and serious medical complications because of its simple operation, low amount of bleeding, quick postoperative recovery, and safe and effective short-term and long-term efficacy. However, it should be carefully selected for patients with a total uterus length exceeding 10 cm.
