RESUMO

BACKGROUND: Surgical intervention is needed in some cases of spontaneous abortion to remove retained products of conception. Antibiotic prophylaxis may reduce the risk of pelvic infection, which is an important complication of this surgery, particularly in low-resource countries. METHODS: We conducted a double-blind, placebo-controlled, randomized trial investigating whether antibiotic prophylaxis before surgery to complete a spontaneous abortion would reduce pelvic infection among women and adolescents in low-resource countries. We randomly assigned patients to a single preoperative dose of 400 mg of oral doxycycline and 400 mg of oral metronidazole or identical placebos. The primary outcome was pelvic infection within 14 days after surgery. Pelvic infection was defined by the presence of two or more of four clinical features (purulent vaginal discharge, pyrexia, uterine tenderness, and leukocytosis) or by the presence of one of these features and the clinically identified need to administer antibiotics. The definition of pelvic infection was changed before the unblinding of the data; the original strict definition was two or more of the clinical features, without reference to the administration of antibiotics. RESULTS: We enrolled 3412 patients in Malawi, Pakistan, Tanzania, and Uganda. A total of 1705 patients were assigned to receive antibiotics and 1707 to receive placebo. The risk of pelvic infection was 4.1% (68 of 1676 pregnancies) in the antibiotics group and 5.3% (90 of 1684 pregnancies) in the placebo group (risk ratio, 0.77; 95% confidence interval [CI], 0.56 to 1.04; P = 0.09). Pelvic infection according to original strict criteria was diagnosed in 1.5% (26 of 1700 pregnancies) and 2.6% (44 of 1704 pregnancies), respectively (risk ratio, 0.60; 95% CI, 0.37 to 0.96). There were no significant between-group differences in adverse events. CONCLUSIONS: Antibiotic prophylaxis before miscarriage surgery did not result in a significantly lower risk of pelvic infection, as defined by pragmatic broad criteria, than placebo.

RESUMO

OBJECTIVE: The objective of this study was to estimate the relative cost effectiveness for the full range of uterotonic drugs available for preventing postpartum haemorrhage (PPH). METHODS: A model-based economic evaluation was constructed using effectiveness data from a network meta-analysis, and supplemented by the literature. A UK National Health Service (NHS) perspective was adopted for the analysis, which is based on UK costs from published sources. The primary outcome measure is cost per case of PPH avoided (≥ 500 mL blood loss), with secondary outcome measures of cost per case of severe PPH avoided (≥ 1000 mL) and cost per major outcome (surgery) averted also being analysed. RESULTS: Carbetocin is shown to be the most effective strategy. Excluding adverse events, 'ergometrine plus oxytocin' was shown to be the least costly strategy. The incremental cost-effectiveness ratio for prevention of PPH with carbetocin compared with prevention with 'ergometrine plus oxytocin' was £1889 per case of PPH ≥ 500 mL avoided; £30,013 per case of PPH ≥ 1000 mL avoided; and £1,172,378 per major outcome averted. Including adverse events in the analysis showed oxytocin to be the least costly strategy. The incremental cost-effectiveness ratio for prevention of PPH with carbetocin compared with prevention with oxytocin was £928 per case of PPH ≥ 500 mL avoided; £22,900 per case of PPH ≥ 1000 mL avoided; and £894,514 per major outcome averted. CONCLUSION: The results suggest carbetocin, oxytocin and 'ergometrine plus oxytocin' could all be favourable options for being the most cost-effective strategy for preventing PPH. Carbetocin could be the preferred choice, especially if the price of carbetocin decreased. Mixed findings mean a clear-cut conclusion cannot be made as to which uterotonic is the most cost effective. Future research should focus on collecting more robust evidence on the probability of having adverse events from the uterotonic drugs, and on adapting the model for low- and middle-income countries.

RESUMO

BACKGROUND: The estimated annual global burden of miscarriage is 33 million out of 210 million pregnancies. Many women undergoing miscarriage have surgery to remove pregnancy tissues, resulting in miscarriage surgery being one of the most common operations performed in hospitals in low-income countries. Infection is a serious consequence and can result in serious illness and death. In low-income settings, the infection rate following miscarriage surgery has been reported to be high. Good quality evidence on the use of prophylactic antibiotics for surgical miscarriage management is not available. Given that miscarriage surgery is common, and infective complications are frequent and serious, prophylactic antibiotics may offer a simple and affordable intervention to improve outcomes. METHODS: Eligible patients will be approached once the diagnosis of miscarriage has been made according to local practice. Once informed consent has been given, participants will be randomly allocated using a secure internet facility (1:1 ratio) to a single dose of oral doxycycline (400 mg) and metronidazole (400 mg) or placebo. Allocation will be concealed to both the patient and the healthcare providers. A total of 3400 women will be randomised, 1700 in each arm. The medication will be given approximately 2 hours before surgery, which will be provided according to local practice. The primary outcome is pelvic infection 2 weeks after surgery. Women will be invited to the hospital for a clinical assessment at 2 weeks. Secondary outcomes include overall antibiotic use, individual components of the primary outcome, death, hospital admission, unplanned consultations, blood transfusion, vomiting, diarrhoea, adverse events, anaphylaxis and allergy, duration of clinical symptoms, and days before return to usual activities. An economic evaluation will be performed to determine if prophylactic antibiotics are cost-effective. DISCUSSION: This trial will assess whether a single dose of doxycycline (400 mg) and metronidazole (400 mg) taken orally 2 hours before miscarriage surgery can reduce the incidence of pelvic infection in women up to 2 weeks after miscarriage surgery. TRIAL REGISTRATION: Registered with the ISRCTN (international standard randomised controlled trial number) registry: ISRCTN 97143849 . (Registered on April 17, 2013).

RESUMO

INTRODUCTION: This study explores the scope of practice of Obstetrics and Gynaecology specialists in Italy, Belgium and England, in light of the growth of professional and patient mobility within the EU which has raised concerns about a lack of standardisation of medical speciality practice and training. METHODS: Semi-structured qualitative interviews were conducted with 29 obstetricians and gynaecologists from England, Belgium and Italy, exploring training and scope of practice, following a common topic guide. Interviews were recorded, transcribed and coded following a common coding framework in the language of the country concerned. Completed coding frames, written summaries and key quotes were then translated into English and were cross-analysed among the researchers to identify emerging themes and comparative findings. RESULTS: Although medical and specialty qualifications in each country are mutually recognised, there were great differences in training regimes, with different emphases on theory versus practice and recognition of different subspecialties. However all countries shared concerns about the impact of the European Working Time Directive on trainees' skills development. Reflecting differences in models of care, the scope of practice of OBGYN varied among countries, with pronounced differences between the public and private sector within countries. Technological advances and the growth of co-morbidities resulting from ageing populations have created new opportunities and greater links with other specialties. In turn new ethical concerns around abortion and fertility have also arisen, with stark cultural differences between the countries. CONCLUSION: Variations exist in the training and scope of practice of OBGYN specialists among these three countries, which could have significant implications for the expectations of patients seeking care and specialists practising in other EU countries. Changes within the specialty and advances in technology are creating new opportunities and challenges, although these may widen existing differences. Harmonisation of the training and scope of practice of OBGYN within Europe remains a distant goal. Further research on the scope of practice of medical professionals would better inform future policies on professional mobility.
