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
BACKGROUND Heavy menstrual bleeding (HMB) is a common problem that affects many British women. When initial medical treatment is unsuccessful, the National Institute for Health and Care Excellence recommends surgical options such as endometrial ablation (EA) or hysterectomy. Although clinically and economically more effective than EA, total hysterectomy necessitates a longer hospital stay and is associated with slower recovery and a higher risk of complications. Improvements in endoscopic equipment and training have made laparoscopic supracervical hysterectomy (LASH) accessible to most gynaecologists. This operation could preserve the advantages of total hysterectomy and reduce the risk of complications. OBJECTIVES To compare the clinical effectiveness and cost-effectiveness of LASH with second-generation EA in women with HMB. DESIGN A parallel-group, multicentre, randomised controlled trial. Allocation was by remote web-based randomisation (1 : 1 ratio). Surgeons and participants were not blinded to the allocated procedure. SETTING Thirty-one UK secondary and tertiary hospitals. PARTICIPANTS Women aged < 50 years with HMB. Exclusion criteria included plans to conceive; endometrial atypia; abnormal cytology; uterine cavity size > 11 cm; any fibroids > 3 cm; contraindications to laparoscopic surgery; previous EA; and inability to give informed consent or complete trial paperwork. INTERVENTIONS LASH compared with second-generation EA. MAIN OUTCOME MEASURES Co-primary clinical outcome measures were (1) patient satisfaction and (2) Menorrhagia Multi-Attribute Quality-of-Life Scale (MMAS) score at 15 months post randomisation. The primary economic outcome was incremental cost (NHS perspective) per quality-adjusted life-year (QALY) gained. RESULTS A total of 330 participants were randomised to each group (total n = 660). Women randomised to LASH were more likely to be satisfied with their treatment than those randomised to EA (97.1% vs. 87.1%) [adjusted difference in proportions 0.10, 95% confidence interval (CI) 0.05 to 0.15; adjusted odds ratio (OR) from ordinal logistic regression (OLR) 2.53, 95% CI 1.83 to 3.48; p < 0.001]. Women randomised to LASH were also more likely to have the best possible MMAS score of 100 (68.7% vs. 54.5%) (adjusted difference in proportions 0.13, 95% CI 0.04 to 0.23; adjusted OR from OLR 1.87, 95% CI 1.31 to 2.67; p = 0.001). Serious adverse event rates were low and similar in both groups (4.5% vs. 3.6%). There was a significant difference in adjusted mean costs between LASH (£2886) and EA (£1282) at 15 months, but no significant difference in QALYs. Based on an extrapolation of expected differences in cost and QALYs out to 10 years, LASH cost an additional £1362 for an average QALY gain of 0.11, equating to an incremental cost-effectiveness ratio of £12,314 per QALY. Probabilities of cost-effectiveness were 53%, 71% and 80% at cost-effectiveness thresholds of £13,000, £20,000 and £30,000 per QALY gained, respectively. LIMITATIONS Follow-up data beyond 15 months post randomisation are not available to inform cost-effectiveness. CONCLUSION LASH is superior to EA in terms of clinical effectiveness. EA is less costly in the short term, but expected higher retreatment rates mean that LASH could be considered cost-effective by 10 years post procedure. FUTURE WORK Retreatment rates, satisfaction and quality-of-life scores at 10-year follow-up will help to inform long-term cost-effectiveness.

Abstract
Recent work has shown that outcomes in clinical trials can be affected by which treatment the trial participants would select if they were allowed to do so, and if they do or do not actually receive that treatment. These influences are known as selection and preference effects, respectively. Unfortunately, they cannot be evaluated in conventional, parallel group trials because patient preferences remain unknown. However, several alternative designs have been proposed, to measure and take account of patient preferences. In this paper, we discuss three preference-based designs (the two-stage, fully randomised, and partially randomised designs). In conventional trials, only the treatment effect is estimable, while the preference-based designs have the potential to estimate some or all of the selection and preference effects. The relative efficiency of these designs is affected by several factors, including the proportion of participants who are undecided about treatments, or who are unable or unwilling to state a preference; the relative preference rate between the treatments being compared, among patients who do have a preference; and the ratio of patients randomised to each treatment. We also discuss the advantages and disadvantages of these designs under different scenarios.

Optimising the two-stage randomised trial design when some participants are indifferent in their treatment preferences. Stat Med 2019; 38:2317-2331.

Abstract
Outcomes in a clinical trial can be affected by any underlying preferences that its participants have for the treatments under comparison and by whether they actually receive their preferred treatment. These effects cannot be evaluated in standard trial designs but are estimable in the alternative two-stage randomised trial design, in which some patients can choose their treatment, while the rest are randomly assigned. We have previously shown that, when all two-stage trial participants have a preferred treatment, the preference effects can be evaluated, in addition to the usual direct effect of treatment. We also determined criteria by which to optimise how many participants should be given a choice of treatment vs being randomised. More recently, we extended our methodology to allow for participants who are unable or unwilling to express a treatment preference if they are assigned to the choice group. In this paper, we show how to optimise the two-stage design when some participants are undecided about their treatment. We demonstrate that the undecided group should be regarded as distinct in the analysis, to obtain valid estimates of the preference effects. We derive the optimal proportion of participants who should be offered a choice of treatment, which in many cases will be close to 50%. More generally, the optima depend on the preference rates for treatments and the proportion of undecided participants, and the parameters of primary interest. We discuss some advantages and disadvantages of the two-stage trial design in this situation and describe a practical example.

HEALTH: laparoscopic supracervical hysterectomy versus second-generation endometrial ablation for the treatment of heavy menstrual bleeding: study protocol for a randomised controlled trial.

Abstract
Background Heavy menstrual bleeding (HMB) is a common problem affecting approximately 1.5 million women in England and Wales with a major impact on their physical, emotional, social and material quality of life. It is the fourth most common reason why women attend gynaecology outpatient clinics and accounts for one-fifth of all gynaecology outpatient referrals. Initial treatment in primary care is medical - either by means of oral or injected medication or the levonorgestrel-intrauterine system (Mirena®). If medical treatment fails then surgical treatment can be offered, either endometrial ablation (EA), which destroys the lining of the cavity of the uterus (endometrium), or hysterectomy, i.e. surgical removal of the uterus. While effective, conventional hysterectomy is invasive and carries a risk of complications due to injury to other pelvic structures. The procedure can be simplified and complications minimised by undertaking a ‘supracervical’ hysterectomy where the cervix is left in situ and only the body of the uterus removed. Recent advances in endoscopic technologies have facilitated increased use of laparoscopic supracervical hysterectomy (LASH) which can be performed as a day-case procedure and is relatively easy for the surgeon to learn. HEALTH (Hysterectomy or Endometrial AbLation Trial for Heavy menstrual bleeding) aims to address the question ‘Is LASH superior to second generation EA for the treatment of HMB in terms of clinical and cost effectiveness?’ Methods/Design Women aged < 50 years, with HMB, in whom medical treatment has failed and who are eligible for EA will be considered for trial entry. We aim to recruit women from approximately 30 active secondary care centres in the UK NHS who carry out both surgical procedures. All women who consent will complete a diary of pain symptoms from day 1 to day 14 after surgery, postal questionnaires at six weeks and six months after surgery and 15 months post randomisation. Healthcare utilisation questions will also be completed at the six-week, six-month and 15-month time-points. Discussion Measuring the comparative effectiveness of LASH vs EA will provide the robust evidence required to determine whether the new technique should be adopted widely in the NHS.

Medical therapy versus radiofrequency endometrial ablation in the initial treatment of heavy menstrual bleeding (iTOM Trial): A clinical and economic analysis. PLoS One 2017; 12:e0188176.

Abstract
BACKGROUND Radiofrequency endometrial ablation (REA) is currently a second line treatment in women with heavy menstrual bleeding (MHB) if medical therapy (MTP) is contraindicated or unsatisfactory. Our objective is to compare the effectiveness and cost burden of MTP and REA in the initial treatment of HMB. METHODS We performed a randomized trial at Mayo Clinic Rochester, Minnesota. The planned sample size was 60 patients per arm. A total of 67 women with HMB were randomly allocated to receive oral contraceptive pills (Nordette ®) or Naproxen (Naprosyn®) (n = 33) or REA (n = 34). Primary 12-month outcome measures included menstrual blood loss using pictorial blood loss assessment chart (PBLAC), patients' satisfaction, and Menorrhagia Multi-Attribute Scale (MMAS). Secondary outcomes were total costs including direct medical and indirect costs associated with healthcare use, patient out-of-pocket costs, and lost work days and activity limitations over 12 months. RESULTS Compared to MTP arm, women who received REA had a significantly lower PBLAC score (median [Interquartile range, IQR]: 0 [0-4] vs. 15 [0-131], p = 0.003), higher satisfaction rates (96.8%vs.63.2%, p = 0.003) and higher MMAS (median [IQR]: 100 [100-100] vs. 100 [87-100], p = 0.12) at 12 months. Direct medical costs were higher for REA ($5,331vs.$2,901, 95% confidence interval (CI) of mean difference:$727,$4,852), however, when indirect costs are included, the difference did not reach statistical significance ($5,469 vs. $3,869, 95% CI of mean difference:-$339, $4,089). CONCLUSION For women with heavy menstrual bleeding, initial radiofrequency endometrial ablation compared to medical therapy offered superior reduction in menstrual blood loss and improvement in quality of life without significant differences in total costs of care.

Estimation of treatment preference effects in clinical trials when some participants are indifferent to treatment choice. BMC Med Res Methodol 2017; 17:29. [PMID: 28219326 PMCID: PMC5319089 DOI: 10.1186/s12874-017-0304-x] [Citation(s) in RCA: 15] [Impact Index Per Article: 2.1] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/16/2016] [Accepted: 02/02/2017] [Indexed: 11/19/2022] Open
Abstract
Background In the two-stage randomised trial design, a randomly sampled subset of study participants are permitted to choose their own treatment, while the remaining participants are randomised to treatment in the usual way. Appropriate analysis of the data from both arms of the study allows investigators to estimate the impact on study outcomes of treatment preferences that patients may have, in addition to evaluating the usual direct effect of treatment. In earlier work, we showed how to optimise this design by making a suitable choice of the proportion of participants who should be assigned to the choice arm of the trial. However, we ignored the possibility of some participants being indifferent to the treatments under study. In this paper, we extend our earlier work to consider the analysis of two-stage randomised trials when some participants have no treatment preference, even if they are assigned to the choice arm and allowed to choose. Methods We compare alternative characterisations of the response profiles of the indifferent or undecided participants, and derive estimates of the treatment and preference effects on study outcomes. We also present corresponding test statistics for these parameters. The methods are illustrated with data from a clinical trial contrasting medical and surgical interventions. Results Expressions are obtained to estimate and test the impact of treatment choices on study outcomes, as well as the impact of the actual treatment received. Contrasts are defined between patients with stated treatment preferences and those with no preference. Alternative assumptions concerning the outcomes of undecided participants are described, and an approach leading to unbiased estimation and testing is identified. Conclusions Use of the two-stage design can provide important insights into determinants of study outcomes that are not identifiable with other designs. The design can remain attractive even in the presence of participants with no stated treatment preference.

Abstract
The treatments under comparison in a randomised trial should ideally have equal value and acceptability – a position of equipoise – to study participants. However, it is unlikely that true equipoise exists in practice, because at least some participants may have preferences for one treatment or the other, for a variety of reasons. These preferences may be related to study outcomes, and hence affect the estimation of the treatment effect. Furthermore, the effects of preferences can sometimes be substantial, and may even be larger than the direct effect of treatment. Preference effects are of interest in their own right, but they cannot be assessed in the standard parallel group design for a randomised trial. In this paper, we describe a model to represent the impact of preferences on trial outcomes, in addition to the usual treatment effect. In particular, we describe how outcomes might differ between participants who would choose one treatment or the other, if they were free to do so. Additionally, we investigate the difference in outcomes depending on whether or not a participant receives his or her preferred treatment, which we characterise through a so-called preference effect. We then discuss several study designs that have been proposed to measure and exploit data on preferences, and which constitute alternatives to the conventional parallel group design. Based on the model framework, we determine which of the various preference effects can or cannot be estimated with each design. We also illustrate these ideas with some examples of preference designs from the literature.

Abstract
BACKGROUND Heavy menstrual bleeding significantly impairs the quality of life of many otherwise healthy women. Perception of heavy menstrual bleeding is subjective and management usually depends upon what symptoms are acceptable to the individual. Surgical options include conservative surgery (uterine resection or ablation) and hysterectomy. Medical treatment options include oral medication and a hormone-releasing intrauterine device (LNG-IUS). OBJECTIVES To compare the effectiveness, safety and acceptability of surgery versus medical therapy for heavy menstrual bleeding. SEARCH METHODS We searched the following databases from inception to January 2016: Cochrane Gynaecology and Fertility Group Trials Register, the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, EMBASE, PsycINFO and clinical trials registers (clinical trials.gov and ICTRP). We also searched the reference lists of retrieved articles. SELECTION CRITERIA Randomised controlled trials (RCTs) comparing conservative surgery or hysterectomy versus medical therapy (oral or intrauterine) for heavy menstrual bleeding. DATA COLLECTION AND ANALYSIS Two review authors independently selected the studies, assessed their risk of bias and extracted the data. Our primary outcomes were menstrual bleeding, satisfaction rate and adverse events. Where appropriate we pooled the data to calculate pooled risk ratios (RRs) or mean differences, with 95% confidence intervals (CIs), using a fixed-effect model. We assessed heterogeneity with the I(2) statistic and evaluated the quality of the evidence using GRADE methods. MAIN RESULTS We included 15 parallel-group RCTs (1289 women). Surgical interventions included hysterectomy and endometrial resection or ablation. Medical interventions included oral medication and the levonorgestrel-releasing intrauterine device (LNG-IUS). The overall quality of the evidence for different comparisons ranged from very low to moderate. The main limitations were lack of blinding, attrition and imprecision. Moreover, it was difficult to interpret long-term study findings as many women randomised to medical interventions subsequently underwent surgery. Surgery versus oral medicationSurgery (endometrial resection) was more effective in controlling bleeding at four months (RR 2.66, 95% CI 1.94 to 3.64, one RCT, 186 women, moderate quality evidence) and also at two years (RR 1.29, 95% CI 1.06 to 1.57, one RCT, 173 women, low quality evidence). There was no evidence of a difference between the groups at five years (RR 1.14, 95% CI 0.97 to 1.34, one RCT, 140 women, very low quality evidence).Satisfaction with treatment was higher in the surgical group at two years (RR 1.40, 95% CI 1.13 to 1.74, one RCT, 173 women, moderate quality evidence), but there was no evidence of a difference between the groups at five years (RR 1.13, 95% CI 0.94 to 1.37, one RCT, 114 women, very low quality evidence). There were fewer adverse events in the surgical group at four months (RR 0.26, 95 CI 0.15 to 0.46, one RCT, 186 women). These findings require cautious interpretation, as 59% of women randomised to the oral medication group had had surgery within two years and 77% within five years. Surgery versus LNG-IUSWhen hysterectomy was compared with LNG-IUS, the hysterectomy group were more likely to have objective control of bleeding at one year (RR 1.11, 95% CI 1.05 to 1.19, one RCT, 223 women, moderate quality evidence). There was no evidence of a difference in quality of life between the groups at five or 10 years, but by 10 years 46% of women originally assigned to LNG-IUS had undergone hysterectomy. Adverse effects associated with hysterectomy included surgical complications such as bladder or bowel perforation and vesicovaginal fistula. Adverse effects associated with LNG-IUS were ongoing bleeding and hormonal symptoms.When conservative surgery was compared with LNG-IUS, at one year the surgical group were more likely to have subjective control of bleeding (RR 1.19, 95% CI 1.07 to 1.32, five RCTs, 281 women, low quality evidence, I(2) = 15%). Satisfaction rates were higher in the surgical group at one year (RR 1.16, 95% CI 1.04, to 1.28, six RCTs, 442 women, I(2) = 27%), but this finding was sensitive to the choice of statistical model and use of a random-effects model showed no conclusive evidence of a difference between the groups. There was no evidence of a difference between the groups in satisfaction rates at two years (RR 0.93, 95% CI 0.81 to 1.08, two RCTs, 117 women, I(2) = 1%).At one year there were fewer adverse events (such as bleeding and spotting) in the surgical group (RR 0.36, 95% CI 0.15 to 0.82, three RCTs, moderate quality evidence). It was unclear what proportion of women assigned to LNG-IUS underwent surgery over long-term follow-up, as there were few data beyond one year. AUTHORS' CONCLUSIONS Surgery, especially hysterectomy, reduces menstrual bleeding more than medical treatment at one year. There is no conclusive evidence of a difference in satisfaction rates between surgery and LNG-IUS, though adverse effects such as bleeding and spotting are more likely to occur with LNG-IUS. Oral medication suits a minority of women in the long term, and the LNG-IUS device provides a better alternative to surgery in most cases. Although hysterectomy is a definitive treatment for heavy menstrual bleeding, it can cause serious complications for a minority of women. Most women may be well advised to try a less radical treatment as first-line therapy. Both LNG-IUS and conservative surgery appear to be safe, acceptable and effective.

An exploratory qualitative assessment of self-reported treatment outcomes and satisfaction among patients accessing an innovative voluntary drug treatment centre in Malaysia. THE INTERNATIONAL JOURNAL OF DRUG POLICY 2015; 26:175-82. [PMID: 25577322 PMCID: PMC4291539 DOI: 10.1016/j.drugpo.2014.10.002] [Citation(s) in RCA: 24] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/25/2013] [Revised: 08/29/2014] [Accepted: 10/19/2014] [Indexed: 01/17/2023]
Abstract
BACKGROUND In Malaysia, compulsory drug detention centres (CDDCs) hold suspected drug users for two years without adjudication. Acute detoxification without healthcare access has been documented. CDDCs are criticized globally due to ineffectiveness in treating addiction and human rights violations. In response, the Malaysian government began transitioning these facilities into voluntary drug treatment centres known as "Cure and Care" (C&C) centres that embrace a holistic treatment-based approach to drug addiction rehabilitation. METHODS An explorative qualitative study was undertaken to explore patient perspectives and satisfaction regarding treatment and services at the new Cure and Care centre in Kota Bharu, Malaysia. A convenience sample of 20 patients was recruited to participate in semi-structured in-depth interviews. Content analysis was used to identify the salient themes. RESULTS Patients identified methadone treatment, psychosocial programs, religious instruction, and recreational activities as important factors contributing to treatment success for addressing both health and addiction needs. Though many had previously been in a CDDC, adherence to treatment in the C&C centre was perceived to be facilitated by the degree of social support, the voluntary nature and the array of new programs available for selection. CONCLUSION C&Cs represents a dramatic shift in the Malaysian government's approach to drug addiction. Our findings demonstrate positive patient experiences associated with the holistic treatment-based approach of these centres. This exploratory study provides additional evidence to document this ongoing policy transition and may guide continued expansion of new holistic drug treatment programs across the country.

Abstract
OBJECTIVE To evaluate procedure-related adverse events, post-procedure menstrual bleeding status, and surgical re-intervention in women with a sounded uterine length > 10 cm compared to women with a sounded uterine length ≤ 10 cm who underwent the NovaSure endometrial ablation procedure. METHODS We conducted a retrospective cohort study of 188 women from a Canadian community-based gynaecology practice. Eighty-seven women had a sounded uterine length > 10 cm, and 101 patients had a sounded length ≤ 10 cm. Procedure-related adverse events, post-procedure menstrual bleeding status, and surgical re-interventions were compared between groups. RESULTS Mean uterine sounding lengths were 11.0 ± 0.6 cm and 8.9 ± 0.8 cm in the > 10 cm and ≤ 10 cm groups, respectively. There were no differences between the groups in demographic characteristics or gynaecologic history, with the exception of higher BMI in the > 10 cm group and a greater prevalence of dysmenorrhea in the ≤ 10 cm group. Overall, 44.1% of all participants had been unsuccessfully treated with hormonal therapy, and 20.7% had failed non-hormonal treatment before the ablation procedure. The remaining 35.2% of participants had declined alternative therapy and proceeded directly to endometrial ablation. No serious procedure-related adverse events occurred in either group. Menstrual bleeding status at follow-up at 30.4 ± 15.3 months (> 10 cm group) and 30.5 ± 15.5 months (≤ 10 cm group) was not different between the groups (P = 0.85). In women who did not undergo surgical re-intervention after the initial ablation, amenorrhea was reported by 51.9% in the > 10 cm group and 65.9% in the ≤ 10 cm group. CONCLUSION The NovaSure endometrial ablation procedure was associated with successful menstrual bleeding outcomes in women with sounded uterine length > 10 cm. No serious procedure-related adverse events occurred, and the need for surgical re-intervention was low. There was no significant difference in bleeding rates between the > 10 cm and ≤ 10 cm uterine length cohorts.

Sample Size and Power When Designing a Randomized Trial for the Estimation of Treatment, Selection, and Preference Effects. Med Decis Making 2014; 34:711-9. [PMID: 24695962 DOI: 10.1177/0272989x14525264] [Citation(s) in RCA: 16] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/15/2013] [Accepted: 05/02/2013] [Indexed: 11/15/2022]
Abstract
BACKGROUND A 2-stage randomized trial design, incorporating participant choice, provides unbiased estimates of the effects of the treatment or intervention (treatment effect), the difference between outcomes for participants who prefer one treatment compared with another (selection effect), and the interaction between participants' preferences for treatment and the treatment actually received (preference effect). It is important to ensure that such trials are adequately powered to estimate these effects. SAMPLE SIZE FORMULAS This paper presents methods for determining the required sample sizes for estimating treatment, selection, and preference effects. We demonstrate the changes in sample size as various key parameters are changed. In general, approximately twice as many participants (in total) are needed to have equivalent power for detecting both treatment and selection/preference effects compared with a trial of the treatment effect alone. PRIMARY SCREENING EXAMPLE We illustrate their application for the design of a primary screening trial comparing human papillomavirus DNA testing versus cervical screening (by Pap smear). Our example would require 520 participants to have 80% power to detect moderate-sized preference and selection effects and a small to moderate treatment effect. CONCLUSIONS With the growing interest in understanding treatment choices and with the use of decision aids, well-designed and adequately powered 2-stage randomized trial designs offer the opportunity to determine the effects of participants' preferences. Our sample size formulas will help future studies ensure that they have adequate power to detect selection and preference effects.

Effect of myoma size on failure of thermal balloon ablation or levonorgestrel releasing intrauterine system treatment in women with menorrhagia. Obstet Gynecol Sci 2013; 56:36-40. [PMID: 24327978 PMCID: PMC3784110 DOI: 10.5468/ogs.2013.56.1.36] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/07/2012] [Revised: 08/20/2012] [Accepted: 09/12/2012] [Indexed: 11/29/2022] Open
Abstract
Objective The aim of the present study was to identify variables associated with treatment failure in women with menorrhagia who were treated with thermal balloon ablation (TBA) or levonorgestrel releasing intrauterine system (LNG-IUS), and to determine if there are subgroups where one treatment type is more effective than the other. Methods The study included 106 women with menorrhagia who were treated with TBA or LNG-IUS at the study institute between January 2003 and December 2007, with a follow-up period greater than 12 months. Data were collected by retrospective review of medical records. Treatment failure was defined as persistent or recurrent menorrhagia within one year after treatment or hysterectomy at any time during follow-up. The relationships between variables and treatment outcome were analyzed using the chi-square or Fisher's exact test. The treatment outcome of TBA was compared with LNG-IUS. Results Sixty-seven women were treated with TBA and 39 women were managed with LNG-IUS. Fifty-two women had a myoma ≥2.5 cm. Treatment failure was observed in 24 women (2 recurrent or persistent menorrhagia and 22 hysterectomies) and myoma size (≥2.5 cm vs. <2.5 cm) was associated with treatment outcome. TBA and LNG-IUS showed similar treatment outcomes. Conclusion A large myoma is a risk factor for treatment failure in women with menorrhagia treated with TBA or LNG-IUS.

Abstract
Outcomes in clinical trials may be affected by the choice of treatment that participants might make, if they were indeed allowed to choose (a so-called selection effect), and by whether they actually receive their preferred treatment (a preference effect). Selection and preference effects can be important, but they cannot be estimated in the conventional trial design. An alternative approach is the two-stage randomised trial, in which participants are first randomly divided into two subgroups. In one subgroup, participants are randomly assigned to treatments, while in the other, participants are allowed to choose their own treatment. This approach yields estimates of the direct treatment effect, and of the preference and selection effects. The latter two provide insight that goes considerably beyond what is possible in the standard randomised trial. In this paper, we determine the optimal proportion of participants who should be allocated to the choice subgroup. The precision of the estimated selection, preference and treatment effects are functions of: the total sample size; the proportion of participants allocated to choose their treatment; the variances of the outcome; the proportions of participants who select each treatment in the choice group; and the selection, preference and treatment effects themselves. We develop general expressions for the optimum proportion of participants in the choice group, depending on which effects are of primary interest. We illustrate the results with trial data comparing alternative clinical management strategies for women with abnormal results on cervical screening.

Abstract
Background. The Rucker 2-stage randomized trial (RCT) design and method allows treatment, preference, and selection effects to be estimated separately in clinical trials. Objective. To understand the effect of patient choice on patient outcomes, the authors applied the Rucker design and analysis method. Design. They used data from a trial of management strategies for women with atypical cells of undetermined significance (ASCUS) detected at routine cervical screening, in which informed choice using a decision aid was compared to no choice. Setting. Women’s health clinics across Australia. Patients. Women aged 18 to 70 years (n = 314) with ASCUS. Intervention. Women were randomized to either an informed choice of human papillomavirus (HPV) triage testing or repeat Pap testing or to no choice with random allocation to management by either option. Measurements. Health-related quality of life (SF36) and satisfaction were measured over the course of management and up to 1 year after triage. Results. Using the Rucker analysis, patients who received their choice had higher quality of life scores than those who did not choose (SF36 MCS, 6% higher, 6.0; 95% confidence interval: −0.6 to 12.9; P = 0.07; effect size 0.61 [moderate]). In contrast, the traditional RCT analysis suggested there was little difference in quality of life between the choice and no-choice trial arms. Limitations. The Rucker method assumes that the declared preferences for treatment in the choice arm are representative of the preferences that would have been observed in the no-choice arms if choice was available. Conclusions. The Rucker method should be used to estimate treatment, preference, and selection effects in randomized trials, as it adds to our understanding of the effect of choice on patient outcomes.

Abstract
OBJECTIVE To summarize and evaluate the patient-based outcome measures (PBOMs) that have been used to study women with abnormal uterine bleeding (AUB). DESIGN Systematic review. SETTING Original articles that used at least one PBOM and were conducted within a population of women with AUB. PATIENT(S) Women with AUB. INTERVENTION(S) The titles, abstracts, and studies were systematically reviewed for eligibility. The PBOMs used in eligible studies were summarized. Essential psychometric properties were identified, and a list of criteria for each property was generated. MAIN OUTCOME MEASURE(S) "Quality" of individual PBOMs as determined using the listed criteria for psychometric properties. RESULT(S) Nine hundred eighty-three studies referenced AUB and patient-reported outcomes. Of these, 80 studies met the eligibility criteria. Fifty different instruments were used to evaluate amount of bleeding, bleeding-related symptoms, or menstrual bleeding-specific quality of life. The quality of each of these instruments was evaluated on eight psychometric properties. The majority of instruments had no documentation of reliability, precision, or feasibility. There was no satisfactory evidence that any one instrument completely addressed all eight psychometric properties. CONCLUSION(S) Studies of women with AUB are increasingly using PBOMs. Many different PBOMs were used; however, no single instrument completely addressed eight important measurement properties.

Abstract
Decision aids (DAs) are tools to support patients make informed health decisions with their practitioner. They aim to improve patient knowledge of options, incorporate patient preferences and values, and increase patient involvement in health decision making. Increasingly, the debate about DAs concerns how they should be implemented in practice, with the view that DAs are superior to usual clinical care in facilitating health decisions. The authors challenge this view and suggest that DA research has focused on measures of decision process, leaving the effects on the outcome of the decision relatively unknown. It is still unclear in which conditions DAs are better for patient health and well-being than clinician-led decisions. The authors present a new randomized design to examine the effects of DA-supported patient choice on patient-centered outcomes to identify where DAs are best implemented in clinical practice. In this design, patients are randomized to 1 of 4 arms: intervention A, intervention B, choice of either intervention supported by a clinician, or choice of either intervention supported by a decision aid. Health and quality of life measured over the long term are presented as the primary outcomes. The authors propose that this design will allow the proper assessment of different modes of decision making.

Abstract
Both hysterectomy for heavy menstrual bleeding and radical mastectomy for breast cancer are steeped in the history of surgery and have recently been challenged as being too radical for the disorder at hand. Radical mastectomy has largely been replaced with local removal of the tumor with subsequent radiation and/or chemotherapy. Alternatives to hysterectomy include a number of medical interventions, most notably intrauterine progestin-releasing systems, and endometrial ablation, a procedure that has a relatively high success rate and one that is now feasible for many women in an office or procedure room setting. However, although radical mastectomy rates have dropped precipitously, hysterectomy rates, at least in the United States remain relatively stable. Determining the proportion of hysterectomies that are done for heavy menstrual bleeding is difficult, largely because of coding issues, so it is difficult to measure the impact of new medical and minimally invasive surgical procedures. Nevertheless, it seems clear that many women are not exposed to the plethora of options to hysterectomy, a fact that may reflect a number of issues that may include training, skill, and financial incentives or disincentives. Clearly, options to hysterectomy are not a panacea, but if women are empowered to select from all of the options available, the rate of hysterectomy for bleeding should decrease while maintaining, or even enhancing the patient's satisfaction with care.

Abstract
OBJECTIVES Abnormal uterine bleeding (AUB) impacts women's health-related quality of life (HRQoL) and puts a heavy economic burden on society. To date, this burden has not been systematically studied. We conducted a systematic review of the medical literature to evaluate the impact of AUB on HRQoL and to quantify the economic burden of AUB from a societal perspective. METHODS We searched the PubMed and Cochrane databases, and article bibliographies for the period up to July 2005. Teams of two reviewers independently abstracted data from studies that reported outcomes of interest: prevalence, HRQoL, work impairment, and health-care utilization and costs associated with AUB. RESULTS The search yielded 1009 English-language articles. Ninety-eight studies (including randomized controlled trials, observational studies, and reviews) that met the inclusion and exclusion criteria underwent a full-text review. The prevalence of AUB among women of reproductive age ranged from 10% to 30%. The HRQoL scores from the 36-item Short-Form Health Survey Questionnaire (SF-36) suggested that women with AUB have HRQoL below the 25th percentile of that for the general female population within a similar age range. The conservatively estimated annual direct and indirect economic costs of AUB were approximately $1 billion and $12 billion, respectively. These figures do not account for intangible costs and productivity loss due to presenteeism. CONCLUSIONS The burden of AUB needs further and more thorough investigation. Additional research should prospectively evaluate the impact of AUB and the value of treatment provided to help guide future health resource allocation and clinical decision-making.

Abstract
OBJECTIVE To compare the acceptability, efficacy, adverse effects, and user satisfaction of a levonorgestrel intrauterine system (LNG-IUS) and transcervical resection of the endometrium (TCRE) for the treatment of dysfunctional uterine bleeding. METHOD Of 50 women with a pictoral blood loss assessment chart (PBAC) score of 100 or greater, 25 had a LNG-IUS inserted (Mirena; Schering, Berlin, Germany) and 25 underwent TCRE. Procedure-related complications, PBAC score, hemoglobin levels, adverse effects, and rates of acceptability and satisfaction were recorded at 3-month intervals for a period of 12 months. RESULTS At the end of 1 year there were a 97% and a 94% reduction in menstrual blood loss in the LNG-IUS and TCRE groups, respectively, and hemoglobin concentration had increased by 5.5% in the LNG-IUS group and 5.2% in the TCRE group. Adverse effects were similar in both groups except for systemic effects, which were seen only in the LNG-IUS group. Satisfaction rates were about 80% in the 2 groups. CONCLUSION Both treatments were found to be equally effective but LNG-IUS placement requires less operator skill and entails no operative hazards, and the device provides effective contraception.

Abstract
BACKGROUND Heavy menstrual bleeding (HMB) significantly impairs the quality of life of many otherwise healthy women. Perception of HMB is subjective and management usually depends upon what symptoms are acceptable to the individual. Medical treatment options include oral medication and a hormone-releasing intrauterine system (LNG-IUS). Surgical options include conservative surgery (uterine resection or ablation) and hysterectomy. OBJECTIVES To compare the effectiveness, safety and acceptability of surgery versus medical therapy for HMB. SEARCH STRATEGY In September 2005 we searched the Cochrane Menstrual Disorders and Subfertility Group trials register Cochrane Controlled Trials Register (The Cochrane Library Issue 3, 2005), MEDLINE EMBASE, Current Contents, Biological Abstracts, PsycINFO, and CINAHL. We also searched reference lists of articles retrieved and contacted pharmaceutical companies and experts in the field. SELECTION CRITERIA Controlled randomised trials comparing conservative surgery or hysterectomy versus medical therapy (oral or intrauterine) for HMB DATA COLLECTION AND ANALYSIS: Two reviewers independently assessed trials for quality and extracted data . MAIN RESULTS The eight included trials randomised 821 women. In comparisons of oral medication versus surgery, 58% of women randomised to medical treatment had received surgery by two years. Compared to oral medication, endometrial resection was significantly more effective in controlling bleeding (at four months: OR 10.62, 95% CI 5.30 to 21.27) and significantly less likely to cause side effects (at four months: OR 0.15, 95% CI 0.07 to 0.31) and hysterectomy resulted in significantly greater improvements in mental health (at six months p = 0.04). In comparisons of LNG-IUS versus conservative surgery or hysterectomy, at one year there was no statistically significant difference in satisfaction rates or quality of life, though adverse effects were significantly less likely with conservative surgery (OR 0.24, 95% CI 0.11 to 0.49). Two trials found conservative surgery significantly more effective than LNG-IUS in controlling bleeding at one year (OR 3.99, 95% CI 1.53 to 10.38). Two other small trials with longer follow-up found no difference or favoured LNG-IUS - however in both these studies the data were skewed and fewer than two thirds of participants were analysed. Hysterectomy stopped all bleeding but caused serious complications for some women. AUTHORS' CONCLUSIONS Surgery, especially hysterectomy, reduces menstrual bleeding at one year more than medical treatments but LNG-IUS appears equally effective in improving quality of life. The evidence for longer term comparisons is weak and inconsistent. Oral medication suits a minority of women long term.

Abstract
BACKGROUND Four types of treatment [hysterectomy, endometrial resection/ablation, levonorgestrel-releasing intrauterine system (LNG-IUS) and oral medical therapy] are available for management of menorrhagia. The objective of this study was to compare the cost and quality-adjusted life-years (QALYs) gained by these four treatment alternatives. METHODS A Markov model was designed to simulate the healthcare resource utilization and QALYs of the four treatment alternatives for patients presenting with menorrhagia over 5 years. Clinical inputs were estimated from literature, and the cost analysis was conducted from the perspective of healthcare provider in Hong Kong. RESULTS The base-case analysis showed that the hysterectomy group was the most effective (4.725 QALYs) alternative with the highest cost (USD6878, 1USD=7.8HKD). The incremental cost per additional QALY (ICER) gained by hysterectomy was USD23 500. The probability of extra surgery in the endometrial resection/ablation was an influential factor. Probabalistic sensitivity analysis of 10,000 simulations of the Monte Carlo model showed that the hysterectomy group gained higher number of QALYs than the LNG-IUS, oral medical treatment and endometrial resection/ablation groups, 99, 99 and 98% of the time, and it was more costly than the other three groups over 85% of the time. CONCLUSIONS Hysterectomy appears to be cost effective, with ICER less than USD50,000, for management of menorrhagia.

Abstract
The simplicity of use and short treatment times of second-generation ablation techniques have increased the likelihood of acceptable treatment under local anaesthetic. Once treatment under local anaesthesia +/- conscious sedation has become accepted, the next step is to explore the viability of moving ablation out of theatre. Whilst there are many series reports of treatment under local anaesthetic, few well-constructed trials have evaluated acceptability and success rates. A reliable anaesthetic regime is available with low failure rates, although problems exist with unpredictable post-operative discomfort and nausea. The optimal treatment package, which will guarantee acceptable treatment with no failures and a quick recovery time allowing for early discharge, is not known. This, along with equipment requirements, safety issues and the need for well-trained support staff, will make outpatient ablation unattractive at present for all but the most determined gynaecologists who have supportive and dynamic staff.

Abstract
OBJECTIVE To compare the efficacy and tolerability of the levonorgestrel intrauterine system (LNG IUS) with mefenamic acid in the management of objective idiopathic menorrhagia. DESIGN Phase III, Single centre, open, randomised, comparative, parallel group study. SETTING District General Hospital in the United Kingdom. POPULATION Fifty-one women with objective menorrhagia. METHODS Twenty-five women randomised to receive the LNG IUS and 26 to oral mefenamic acid for six cycles. MAIN OUTCOME MEASURES Change from baseline in menstrual blood loss (MBL), total menstrual fluid loss (TMFL) and pictorial blood loss assessment chart (PBAC) score at the third and sixth cycle of treatment. RESULTS After six cycles the median menstrual blood loss was 5 mL in the LNG IUS group and 100 mL in the mefenamic acid group (P < 0.001). Median TMFL was 27 mL in the LNG IUS group and 157 mL in the mefenamic acid group (P < 0.001). Median PBAC score was 25 in the LNG IUS group and 159 in the mefenamic acid group. Changes in menstrual blood loss correlated strongly to changes in TMFL (r= 0.88) but PBAC correlated less well to blood loss and total fluid loss (r= 0.53 and r= 0.58). CONCLUSIONS Both the LNG IUS and mefenamic acid significantly decreased menstrual blood loss, TMFL and PBAC scores. The LNG IUS produced greater reductions in all parameters than mefenamic acid. Comparison of the different measurements suggests that TMFL assessment may be an easier and a more relevant measure of symptom severity than menstrual blood loss.

Abstract
OBJECTIVE To compare health-related quality of life (HRQoL) after bipolar radio frequency ablation and thermal balloon ablation in women with dysfunctional uterine bleeding. DESIGN Randomized clinical trial. SETTING Teaching hospital. PATIENT(S) Women suffering from dysfunctional uterine bleeding. INTERVENTION(S) Bipolar radio frequency ablation and thermal balloon ablation. MAIN OUTCOME MEASURE(S) Patients were asked to complete HRQoL questionnaires at baseline, and at 2 days, 2 weeks, 3 months, 6 months, and 12 months after surgery. The questionnaires contained the medical outcomes study Short-Form 36 (SF-36), the Self-rating Depression Scale, the Rotterdam Symptom Checklist, State-Trait Anxiety Inventory, and a structured clinical history questionnaire. RESULT(S) Data on HRQoL were available on at least two different time points in 115 of 126 randomized patients. HRQoL improved significantly over time in both groups, except for the domain of general health in the SF-36. None of the dimensions showed a significant difference between both groups, neither was there a significant interaction between time and treatment effect. CONCLUSION(S) Both methods significantly improved HRQoL in women with dysfunctional uterine bleeding. However, despite better amenorrhea and satisfaction rates after bipolar radio frequency ablation, there was no difference in HRQoL between the two groups.

Abstract
OBJECTIVE To conduct a prospective and concurrent evaluation of changes in health status and quality of life and psychological outcome measures over one year in women randomised to total or subtotal abdominal hysterectomy. The concurrent evaluation was the impact of total versus subtotal hysterectomy on bladder, bowel and sexual function. DESIGN Prospective, randomised, double-blind study. SETTING A large UK Teaching Hospital (St George's Hospital, London) and a large District General Hospital (Mayday University Hospital, Croydon). METHODS. SAMPLE Two hundred and seventy-nine women undergoing hysterectomy for benign disease were randomly allocated to total hysterectomy (n= 146) or subtotal hysterectomy (n= 133). MAIN OUTCOME MEASURES Quality of life assessment using the Short-Form-36 health survey (SF-36) and psychological outcome measures using the General Health Questionnaire-28 (GHQ-28) before the operation and 6 and 12 months after. RESULTS Quality of life and psychological symptoms were similar in the two groups at baseline. Following surgery, quality of life improved in six of the eight domains, with no significant difference between the groups, with the exception of emotions which showed a greater improvement in subtotal hysterectomy women between baseline and 12 months. When this difference was examined further by looking at change in the GHQ subscales, there were no significant differences between total and subtotal hysterectomy women in the amount of change in anxiety, depression, somatic symptoms or social dysfunction, between baseline and post-operative measurements. All women showed an improvement in psychological symptoms following both operations. CONCLUSION Hysterectomy, whether total or subtotal, may improve quality of life and psychological outcome.

Current treatment of dysfunctional uterine bleeding. Maturitas 2004; 47:159-74. [PMID: 15036486 DOI: 10.1016/j.maturitas.2003.08.002] [Citation(s) in RCA: 20] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/25/2003] [Revised: 07/10/2003] [Accepted: 08/07/2003] [Indexed: 10/26/2022]
Abstract
OBJECTIVES We performed a review of the treatment modalities for dysfunctional uterine bleeding. METHODS Dysfunctional uterine bleeding can be treated medically or surgically. Medical treatment consists of anti-fibrinolytic tranexamic acid, non-steroidal anti-inflammatory drugs, the combined contraception pill, progestogen, danazol, or analogues of gonadotrophin releasing hormone. The levonorgestrel releasing intra uterine device is developed for contraception, but is also effective in the treatment of dysfunctional uterine bleeding. Surgical treatment includes endometrial ablation of the first and second-generation, and hysterectomy. This review contains current available evidence on the effectiveness of these therapies. RESULTS Antifibrinolytic tranexamic acid is the most effective medical therapy to treat dysfunctional uterine bleeding. In general medical therapy is not as effective as endometrial resection in terms of patient satisfaction and health related quality of life. The levonorgestrel releasing intra uterine device is an effective treatment for dysfunctional uterine bleeding. No difference in quality of life was observed in patients treated with a levonorgestrel releasing intra uterine device as compared to hysterectomy. Ablation techniques of the first generation are effective and safe when used by trained surgeons, but have a learning curve. Ablation techniques of the second generation are effective, but long-term follow-up data are not available. Similarly, there are no large randomised controlled trials comparing the levonorgestrel releasing intra uterine device to first and second-generation ablation techniques. Hysterectomy, the traditional standard of care, has a relatively high complication rate, but it generates a high satisfaction rate and good health related quality of life scores. CONCLUSION Since none of the treatments for dysfunctional bleeding is superior to one of the others, and since all treatments have their advantages and disadvantages, counselling of patients with dysfunctional bleeding should incorporate medical approach, levonorgestrel releasing IUD, endometrial ablation and hysterectomy.

Abstract
CONTEXT Hysterectomy is a common and effective treatment for menorrhagia but is associated with substantial post-operative convalescence time and morbidity. In the early 1990s endometrial resection or ablation became a well-established day-case alternative for the surgical treatment of menorrhagia. Both endometrial resection and ablation require general anaesthesia, a high level of skill in hysteroscopic surgery, and can be long procedures. More recently, various new techniques have been developed that can be done in an outpatient setting under local anaesthesia and with a low risk of complications. The effectiveness of most new second-generation ablation technologies has not been confirmed in randomised trials and it is possible that these techniques will not prove to be as effective or as safe as originally thought. STARTING POINT Massimiliano Pellicano and colleagues (Am J Obstet Gynecol 2002; 187: 545-50) compared a second-generation ablation technique, thermal destruction of the endometrium with a heated-water-filled silicone balloon with hysteroscopic endometrial resection. 82 women were randomised and followed up for 2 years. Thermal destruction was quicker than hysteroscopic resection, and was associated with a similar level of postoperative satisfaction and reintervention rate. This study suggests that thermal destruction is as effective a technique as endometrial resection. WHERE NEXT? Many second-generation ablation techniques are now available. Some may prove more effective than others, but much larger studies are needed to address safety. The development of progestagen-releasing intrauterine devices, which provide effective treatment for menorrhagia and are also an effective and reversible form of contraception, may mean that the uptake of second-generation surgical ablation techniques is less widespread than some proponents of these new technologies suggest.

Abstract
BACKGROUND Heavy menstrual bleeding significantly impairs the quality of life of many otherwise healthy women. Perception of heavy bleeding is highly subjective and management of the condition usually depends upon the degree of bleeding and discomfort found acceptable by the individual woman. Medical treatment options include oral medications and a hormone-releasing intrauterine system (LNG-IUS). Surgical options include conservative surgery (uterine resection or ablation) and hysterectomy. OBJECTIVES To compare the effectiveness, safety and acceptability of surgery versus medical therapy for heavy menstrual bleeding. SEARCH STRATEGY We searched the Cochrane Menstrual Disorders and Subfertility Group trials register (October 2002), Cochrane Controlled Trials Register (Issue 3, 2002), MEDLINE (1966 to October 2002), EMBASE (1980 to October 2002), Current Contents (1993 to week 45, 2002), Biological Abstracts (1969 to September 2002), PsycINFO (1985 to October 2002), CINAHL (1982 to October 2002), and reference lists of articles. We also contacted pharmaceutical companies and experts in the field. SELECTION CRITERIA Controlled randomised trials comparing surgery (conservative surgery and hysterectomy) versus medical therapy (both oral and intrauterine) for heavy menstrual bleeding DATA COLLECTION AND ANALYSIS Two reviewers independently assessed trials for quality and extracted data, calculating odds ratios for dichotomous outcomes and weighted mean differences for continuous outcomes. MAIN RESULTS Five trials met the inclusion criteria. They randomised 625 women, 311 to receive surgery and 314 to receive medical treatment. One trial compared endometrial resection with oral medication: surgery proved significantly more effective in controlling bleeding (OR 10.62, 95% CI 5.30 to 21.27) and significantly less likely to cause side effects (OR 0.15, 95% CI 0.07 to 0.31). In the other four trials the medical arms received LNG-IUS and the surgical arms received conservative surgery or hysterectomy. At one year no statistically significant difference was shown between LNG-IUS and any surgical treatment in satisfaction rates or quality of life, though conservative surgery was significantly less likely to cause adverse effects (OR 0.24, 95% CI 0.11 to 0.49). Although conservative surgery was significantly more effective than LNG-IUS in controlling bleeding at one year (OR 3.99, 95% CI 1.53 to 10.38), a small trial showed no significant difference between the treatments at two and three years. Hysterectomy stopped all bleeding but caused serious complications for some women. REVIEWER'S CONCLUSIONS Surgery reduces menstrual bleeding at one year more than medical treatments, but LNG-IUS appears equally beneficial in improving quality of life and may control bleeding as effectively as conservative surgery over the long term. Oral medication suits a minority of women long term.

Abstract
OBJECTIVE This study was undertaken to compare the relative efficacy and safety of hysteroscopic endometrial resection and laparoscopic supracervical hysterectomy in the treatment of abnormal uterine bleeding. STUDY DESIGN One hundred eighty-one patients affected by menometrorrhagia and unresponsive to medical treatment agreed to be randomized to either laparoscopic supracervical hysterectomy or hysteroscopic endometrial ablation. They were monitored for 2 years to evaluate perioperative and postoperative outcomes, resolution of symptoms, and patient satisfaction. RESULTS Duration of hospitalization, period of convalescence, perioperative complications, and resumption of normal activity were similar between the two groups. Operative time was significantly shorter in the hysteroscopic group, but patient satisfaction was significantly higher in the laparoscopic group. CONCLUSION For the treatment of menorrhagia, hysterectomy has the distinct advantage of being curative but the disadvantage of being more invasive than the hysteroscopic approach. However, laparoscopic supracervical hysterectomy preserves the curative effect of hysterectomy without its increased surgical invasiveness, as suggested by the current study.

Abstract
BACKGROUND The use of quality of life (QoL) instruments in menorrhagia research is increasing but there is concern that not enough emphasis is placed on patient-focus in these measurements, i.e. on issues which are of importance to patients and reflect their experiences and concerns (clinical face validity). The objective was to assess the quality of QoL instruments in studies of menorrhagia. STUDY DESIGN A systematic review of published research. Papers were identified through MEDLINE (1966-April 2000), EMBASE (1980-April 2000), Science Citation Index (1981-April 2000), Social Science Citation Index (1981-April 2000), CINAHL (1982-1999) and PsychLIT (1966-1999), and by manual searching of bibliographies of known primary and review articles. Studies were selected if they assessed women with menorrhagia for life quality, either developing QoL instruments or applying them as an outcome measure. Selected studies were assessed for quality of their QoL instruments, using a 17 items checklist including 10 items for clinical face validity (issues of relevance to patients' expectations and concerns) and 7 items for measurement properties (such as reliability, responsiveness, etc.). RESULTS A total of 19 articles, 8 on instrument development and 11 on application, were included in the review. The generic Short Form 36 Health Survey Questionnaire (SF36) was used in 12/19 (63%) studies. Only two studies developed new specific QoL instruments for menorrhagia but they complied with 7/17 (41%) and 10/17 (59%) of the quality criteria. Quality assessment showed that only 7/19 (37%) studies complied with more than half the criteria for face validity whereas 17/19 (90%) studies complied with more than half of the criteria for measurement properties (P = 0.0001). CONCLUSION Among existing QoL instruments, there is good compliance with the quality criteria for measurement properties but not with those for clinical face validity. There is a need to develop methodologically sound disease specific QoL instruments in menorrhagia focussing both on face validity and measurement properties.

Abstract
OBJECTIVE The purpose of this study was to compare the satisfaction rate and the effectiveness of transcervical hysteroscopic endometrial resection and thermal destruction of the endometrium in the treatment of menorrhagia. STUDY DESIGN A prospective randomized trial with 2 years of follow-up was carried out in the Department of Gynecology of the University of Naples. Eighty-two patients who were affected by menorrhagia that was unresponsive to medical treatment were respectively randomized to transcervical hysteroscopic endometrial resection or to thermal destruction of the endometrium. Satisfaction rate, operative time, discharge time, complication rate, reintervention rate, and resumption of normal activity were evaluated in each group. RESULTS The satisfaction rate was significantly higher in the thermal destruction group. Operative time was significantly shorter in the thermal destruction group (24 +/- 4 minutes vs 37 +/- 6 minutes). Intraoperative blood loss was significantly lower in the thermal destruction group (7.2 +/- 2.8 mL vs 89 +/- 38 mL). Reintervention rates were higher in the transcervical hysteroscopic endometrial resection group, although postoperative pain was not significantly different between the two groups. Discharge time, complication rate, and resumption of normal activity were not significantly different between the two groups. CONCLUSION Thermal destruction of the endometrium for the treatment of menorrhagia should be considered an effective therapeutic option because of its acceptability among patients, shorter operative time, and lower blood loss.

Abstract
Endometriosis, menorrhagia, chronic pelvic pain, and polycystic ovary syndrome are major sources of psychologic morbidity and can negatively affect quality of life. Although comparative studies have been published on the measurement of health-related quality of life for gynecologic malignancies, a similar review for these benign gynecologic conditions has not been conducted. Consequently, we searched the literature systematically to identify the impact of symptoms and treatments for these conditions on health status and to report on the types and psychometric properties of the instruments used. Papers were retrieved by systematically searching 6 electronic databases and hand-searching relevant reference lists and bibliographies. Forty-six studies used a questionnaire to measure health status: 34 studies (74%) used standardized instruments; of these, 23 studies (68%) used generic tools. Although a meta analysis was not possible, it appears that women with chronic pelvic pain and conditions that are associated with pelvic pain (such as endometriosis) report worse health-related quality of life. Despite the development of disease-specific questionnaires, only 2 questionnaires were generated from interviews of patients with the condition of interest, and few questionnaires are being used to evaluate the outcomes of treatment on subjective health status.

Abstract
STUDY OBJECTIVE To analyze factors that contribute to long-term success of loop endometrial resection (ER). DESIGN Observational cohort study (Canadian Task Force classification II-2). SETTING Tertiary care university hospital. PATIENTS Two hundred eighty-six premenopausal women with menometrorrhagia resistant to medical treatment. INTERVENTION Loop endometrial resection. MEASUREMENTS AND MAIN RESULTS Mean follow-up was 47 months. Life table analysis with log rank test was determined to calculate the risk of hysterectomy after ER. Patient age, length of follow-up, adenomyosis, and uterine size were analyzed independently. More than 75% of patients benefited from the procedure, avoiding hysterectomy after 5 years. CONCLUSION Length of follow-up, patient age, and the presence of adenomyosis strongly influence the long-term success of ER. The procedure should be considered an intermediate step between medical treatment and hysterectomy.

Abstract
OBJECTIVE To compare microwave endometrial ablation (MEA) with a levonorgestrel-releasing intrauterine device (Mirena) in the management of heavy menstrual bleeding. DESIGN A retrospective cohort study SAMPLE Thirty-nine women were treated with MEA and 23 women with Mirena, in the South East Regional Health Service of South Australia during 1998 to 2001; the mean duration of follow-up was 14.6 months. MAIN OUTCOME MEASURES Primary measures included acceptability of the treatment process, effectiveness of the treatment, and satisfaction with outcomes. Secondary measures included side effects, complications and quality of life (using the SF-36). RESULTS Acceptability of the treatment process and satisfaction with outcomes was very high for both procedures. Each treatment led to a statistically significant reduction in menstrual bleeding (p < 0.0001) and dysmenorrhoea scores (p < 0.002). CONCLUSIONS There were no statistical differences between the two treatments for any of the primary or secondary outcome measures assessed. The treatments seem equally effective in the management of heavy menstrual loss.

Abstract
OBJECTIVE To assess clinical status, changes in health related quality of life, and subsequent management five years after medical management or transcervical resection of the endometrium for treatment of heavy menstrual loss. DESIGN Five year follow up using postal questionnaires and operative databank review. SETTING Gynaecology department of a large UK teaching hospital. POPULATION Women referred to the gynaecologist for treatment of heavy menstrual loss. METHODS Eligible women, without a treatment preference, were randomised equally to either medical treatment or transcervical resection of the endometrium. MAIN OUTCOME MEASURES Women's satisfaction with treatment, menstrual status, changes in health related quality of life, and additional treatments received at five years. RESULTS One hundred and forty-four patients completed questionnaires, achieving 77% follow up (medical n = 71/94; transcervical resection of the endometrium n = 73/93). At five-year follow up, 7/71 (10%) of those randomised to the medical arm still used medical treatment, while 72/94 (77%) had undergone surgical treatment and 17/94 (18%) a hysterectomy. Twenty-five (27%) women allocated to transcervical resection of the endometrium had undergone further surgery, 18/93 (19%) a hysterectomy. At five years women initially randomised to medical treatment were significantly less likely to be totally satisfied (P < 0.01, difference 21%, 95% CI -37% to -4%), or to recommend their allocated treatment to a friend (P < 0.001, difference 59%, 95% CI -73% to -45%). Bleeding and pain scores were similar in both groups and highly significantly reduced. Significantly more women in the transcervical resection of the endometrium arm had no bleeding or very light bleeding (P < 0.02, difference -22%, CI -31% to -4%), and they had significantly less days heavy bleeding (P < 0.02). Short Form 36 health survey scores were significantly improved from baseline for all eight health scales in the transcervical resection of the endometrium arm, and four in the medical arm. CONCLUSIONS A policy of immediate transcervical resection of the endometrium for women referred to a gynaecologist for treatment of heavy menstrual loss achieves higher levels of satisfaction, better menstrual status, and greater improvements in health related quality of life than medical treatment. In addition, transcervical resection of the endometrium is safe and does not lead to an increase in the number of hysterectomies. An effective endometrial ablative technique should be offered to all eligible women seeking treatment of their heavy menses from a gynaecologist.

Abstract
BACKGROUND Various new endometrial ablation techniques have emerged for the treatment of menorrhagia. We undertook a randomised controlled trial comparing one new technique, microwave endometrial ablation (MEA), with a proven procedure, transcervical resection of the endometrium (TCRE), for women with heavy menstrual loss. METHODS 263 eligible and consenting women, referred for endometrial ablative surgery, were randomly assigned MEA (Microsulis plc, Waterlooville, Hampshire, UK; n=129) or TCRE (n=134). 230 participants were needed to give 80% power of demonstrating a 15% difference in satisfaction with treatment. All procedures were done under general anaesthesia 5 weeks after endometrial thinning with goserelin 3.6 mg. Questionnaires were completed at recruitment and at 12 months' follow-up. The primary outcome measures were patients' satisfaction with and the acceptability of treatment. Analysis was by intention to treat among women followed up to 12 months (n=116 MEA, n=124 TCRE). FINDINGS At 12 months, 89 (77%) women in the MEA group and 93 (75%) in the TCRE group were totally or generally satisfied with their treatment (95% CI for difference -12 to 17) and 109 (94%) versus 112 (90%) found it acceptable (-11 to 35). Mean operating times were shorter for MEA than for TCRE (11.4 vs 15.0 min, p=0.001) and the postoperative stay slightly but not significantly shorter. One blunt perforation occurred in each study group resulting in one immediate hysterectomy (TCRE group). Of eight health-related quality of life dimensions, all were improved after MEA (six significantly) and seven were improved after TCRE (all significantly). INTERPRETATION Both techniques achieved high rates of satisfaction and acceptability and both improved quality of life after 1 year. However, we cannot exclude a difference in satisfaction between the groups of less than 15%. MEA seems a suitable alternative to TCRE.
