RESUMO

In efforts to strive for family planning repositioning in Botswana, the Ministry of Health convened a meeting to undertake an adaptation of the Medical eligibility criteria for contraceptive use (MEC) wheel. The main objectives of this process were to present technical updates of the various contraceptive methods, to update the current medical conditions prevalent to Botswana and to adapt the MEC wheel to meet the needs of the Botswanian people. This commentary focuses on the adaptation process that occurred during the week-long stakeholder workshop. It concludes with the key elements learned from this process that can potentially inform countries who are interested in undergoing a similar exercise to strengthen their family planning needs.

RESUMO

BACKGROUND: Despite their high effectiveness, progestin-only contraceptives are considered less than ideal by the many women who experience irregular vaginal bleeding when using them. Current treatments to control these bleeding problems are not sufficiently effective. OBJECTIVES: We evaluated preventive and therapeutic approaches to normalise bleeding irregularities associated with the use of progestin-only contraceptives. SEARCH METHODS: Literature was identified through database searches, reference lists, organisations and individuals, covering the period until May-June 2012. SELECTION CRITERIA: Trials with random or systematic allocation, testing interventions for the prevention or treatment of bleeding irregularities associated with the use of progestin-only contraceptives were eligible. DATA COLLECTION AND ANALYSIS: Results are expressed as relative risks (RR) with 95% confidence interval (CI) for categorical data and as weighted mean difference (WMD) with 95% CI for continuous data. When we encountered heterogeneity (visual or statistical) we used the random-effects model (quantitative) or did not produce a summary estimate (qualitative). MAIN RESULTS: Thirty-three randomised controlled trials enrolling 3677 participants were included. Two thirds of the trials were determined to reflect low to moderate risk of bias.Estrogen treatments reduced the number of days of an ongoing bleeding episode in DMPA and Norplant users. However, treatment frequently led to more discontinuation due to gastrointestinal upset.Combinations of oral ethinyl estradiol and levonorgestrel improved bleeding patterns in Norplant users, but method discontinuation rates were unchanged. One trial reported successful use of combined oral contraceptives in treating amenorrhea among DMPA users.Norplant users, but not Implanon users, administered the anti-progestin mifepristone reported fewer days of bleeding during treatment than those given placebo. Mifepristone used monthly by new Norplant acceptors reduced bleeding, when compared to placebo.A variety of NSAIDS have been evaluated for their ability to treat abnormal bleeding, with mixed results.Norplant users receiving SERM (tamoxifen) had less unacceptable bleeding after treatment and were more likely to continue using Norplant than those receiving placebo.Tranexamic acid, mifepristone combined with an estrogen and doxycycline were more effective than placebo in terminating an episode of bleeding in women using progestin-only contraceptives, according to three small studies. AUTHORS' CONCLUSIONS: Some women may benefit from the interventions described, particularly with cessation of current bleeding. Several regimens offer promise in regulating bleeding, but findings need to be reproduced in larger trials. The results of this review do not support routine clinical use of any of the regimens included in the trials, particularly for long-term effect.

RESUMO

OBJECTIVES: Digital adaptation kits (DAKs) distill WHO guidelines for digital use by representing them as workflows, data dictionaries and decision support tables. This paper aims to highlight key lessons learnt in coding data elements of the antenatal care (ANC) and family planning DAKs to standardised classifications and terminologies (CATs). METHODS: We encoded data elements within the ANC and family planning DAKs to standardised CATs from the WHO CATs and other freely available CATs. RESULTS: The coding process demonstrated approaches to refine the data dictionaries and enhance alignment between data elements and CATs. DISCUSSION: Applying CATs to WHO clinical and public health guidelines can ensure that recommendations are operationalised in a digital system with appropriate consistency and clarity. This requires a multidisciplinary team and careful review to achieve conceptual equivalence between data elements and standardised terminologies. CONCLUSION: The systematic translation of guidelines into digital systems provides an opportunity for leveraging CATs; however, this approach needs further exploration into its implementation in country contexts and transition into machine-readable components.

RESUMO

In Belarus and several EECA countries, periodic population-based chest X-ray "fluorography programme" use as a mass screening tool for the diagnosis of tuberculosis (TB) has been used for decades. This mass screening has also often been justified for the early detection of lung cancer (LC), although no mortality benefits were demonstrated by screening with chest X-ray in international randomized trials. In Belarus, fluorography testing is mandatory every one to three years for all adults depending on age and the so-called "risk groups". The World Bank and WHO estimate that Belarus spends USD11 million annually on mass fluorography screening and advocate for more targeted screening approaches to increase diagnostic yield for TB and not to use it for screening for LC. The study is a retrospective review of medical records to assess the yield of fluorography to detect true cases of LC and/or TB in asymptomatic patients in two rural and two urban districts in Belarus for 2015-2017 with positive screening results for presumed of TB or LC. The study provided the rationale to implement the improved policy and practices regarding the role of fluorography in the early detection of LC and TB in Belarus and elsewhere.

RESUMO

INTRODUCTION: Depot medroxyprogesterone acetate subcutaneous injectable contraception (DMPA-SC) may facilitate self-administration and expand contraceptive access. To inform WHO guidelines on self-care interventions, we conducted a systematic review and meta-analysis comparing self-administration versus provider administration of injectable contraception on outcomes of pregnancy, side effects/adverse events, contraceptive uptake, contraceptive continuation, self-efficacy/empowerment and social harms. METHODS: We searched PubMed, Cumulative Index to Nursing and Allied Health Literature, LILACS and EMBASE in September 2018 for peer-reviewed studies comparing women who received injectable contraception with the option of self-administration with women who received provider-administered injectable contraception on at least one outcome of interest. Risk of bias was assessed using the Cochrane tool for randomised controlled trials (RCTs) and the Evidence Project tool for non-randomised studies. Meta-analysis was conducted using random-effects models to generate pooled estimates of relative risk (RR). RESULTS: Six studies with 3851 total participants met the inclusion criteria: three RCTs and three controlled cohort studies. All studies examined self-injection of DMPA-SC; comparison groups were either provider-administered DMPA-SC or provider-administered intramuscular DMPA. All studies followed women through 12 months of contraceptive coverage and measured (dis)continuation of injectable contraception. Meta-analysis found higher rates of continuation with self-administration compared with provider administration in three RCTs (RR: 1.27, 95% CI 1.16 to 1.39) and three controlled cohort studies (RR: 1.18, 95% CI 1.10 to 1.26). Four studies reported pregnancies; all showed no difference across study arms. Four studies reported side effects/adverse events; while two controlled cohort studies showed increased injection site reactions with self-administration, no other side effects increased with self-administration. One study found no difference in social harms. No studies reported measuring uptake or self-efficacy/empowerment. CONCLUSION: A growing evidence base suggests that self-administration of DMPA-SC can equal or improve contraceptive continuation rates compared with provider administration. This benefit comes without notable increases in pregnancy or safety concerns. Self-injection of DMPA-SC is a promising approach to increasing contraceptive use.

RESUMO

The World Health Organization (WHO) is responsible for providing evidence-based family planning guidance for use worldwide. WHO currently has two such guidelines, Medical Eligibility Criteria for Contraceptive Use and Selected Practice Recommendations for Contraceptive Use, which are widely used globally and often incorporated into national family planning standards and guidelines. To ensure that these guidelines remain up-to-date, WHO, in collaboration with the Centers for Disease Control and Prevention and the Information and Knowledge for Optimal Health (INFO) Project at the Johns Hopkins Bloomberg School of Public Health's Center for Communication Programs, has developed the Continuous Identification of Research Evidence (CIRE) system to identify, synthesize, and evaluate new scientific evidence as it becomes available. The CIRE system identifies new evidence that is relevant to current WHO family planning recommendations through ongoing review of the input to the POPulation information onLINE (POPLINE) database. Using the Meta-Analysis of Observational Studies in Epidemiology guidelines and standardized abstract forms, systematic reviews are conducted, peer-reviewed, and sent to WHO for further action. Since the system began in October 2002, 90 relevant new articles have been identified, leading to 43 systematic reviews, which were used during the 2003-2004 revisions of WHO's family planning guidelines. The partnership developed to create and manage the CIRE system has pooled existing resources; scaled up the methodology for evaluating and synthesizing evidence, including a peer-review process; and provided WHO with finger-on-the-pulse capability to ensure that its family planning guidelines remain up-to-date and based on the best available evidence.

RESUMO

BACKGROUND: Emergency contraceptive pills (ECPs) are an underutilized means to reduce unintended pregnancy. Advance provision of ECPs may increase timely use, thereby decreasing risk of unintended pregnancy. STUDY DESIGN: We searched MEDLINE and EMBASE through February 2012 for randomized, controlled trials (RCTs) pertaining to safety and efficacy of advance provision of ECP. The quality of each individual study was evaluated using the United States Preventive Services Task Force evidence grading system. RESULTS: The search strategy identified 714 articles. Seventeen papers reported on safety or efficacy of advance ECPs in adult or adolescent women. Any use of ECPs was two to seven times greater among women who received an advanced supply of ECP. However, a summary estimate (RR 0.90, 95% CI 0.69-1.18) of four RCTs did not demonstrate a significant reduction in unintended pregnancy over 12 months when advance provision was compared with standard provision of ECPs. Patterns of contraceptive use, pregnancy rates and incidence of sexually transmitted infections did not vary between treatment and control groups in the majority of studies among either adults or adolescents. CONCLUSION: Available evidence supports the safety of advance provision of ECPs. Efficacy of advance provision compared with standard provision of ECPs in reducing unintended pregnancy rates at the population level has not been demonstrated.

RESUMO

BACKGROUND: The objective of this systematic review is to determine whether obese women who use progestogen-only contraceptives are more likely to experience weight gain or serious adverse events as compared to nonobese users. STUDY DESIGN: We searched PubMed for all articles (in all languages) published in peer-reviewed journals from database inception through October 2008, for evidence relevant to obesity and progestogen-only contraceptives. We used standard abstract forms and grading systems to summarize and assess the quality of the evidence. RESULTS: From 579 articles, we identified nine studies fitting our selection criteria. Evidence from five studies suggests that among adult women, baseline weight or body mass index is not associated with weight gain among depot medroxyprogesterone acetate (DMPA) users (Level II-2, Fair). Evidence from three studies suggests that among adolescent women, overweight or obese DMPA users may gain more weight than normal weight DMPA users or overweight/obese nonusers (Level II-2, Fair). Evidence from one small study of Norplant users showed no differences in weight gain by baseline weight (Level II-3, Poor). We did not identify studies of other progestogen-only contraceptive methods that examined weight change by baseline weight, nor did we identify studies that reported on any serious adverse events by baseline weight. CONCLUSIONS: Adolescent DMPA users who are obese may gain more weight than normal weight users. This observation was not seen in adult DMPA users or adolescent Norplant users.
