Developing and applying a 'living guidelines' approach to WHO recommendations on maternal and perinatal health

Antidepressant prescriptions have not fully reflected evolving evidence from cumulative network meta-analyses and guideline recommendations

OBJECTIVES

This study compares three major elements of evidence-based medicine (EBM) practices, namely evidence synthesis, clinical practice guidelines (CPGs), and real-world prescriptions in the United States, regarding antidepressant treatments of major depression over the past 3 decades.

STUDY DESIGN AND SETTING

We conducted network meta-analyses (NMAs) of antidepressants every 5 years up to 2016 based on a comprehensive data set of double-blind randomized controlled trials. We identified CPGs and extracted their recommendations. We surveyed the prescriptions in the United States at 5-year intervals up to 2015.

RESULTS

Most drugs recommended by CPGs presented favorable performance in efficacy and acceptability in NMAs. However, CPG recommendations were often in terms of drug classes rather than individual drugs, whereas NMAs suggested distinctive difference between drugs within the same class. The update intervals of all CPGs were longer than 5 years. All the antidepressants prescribed frequently in the United States were recommended by CPGs. However, changes in prescriptions did not correspond to alterations in CPGs or to apparent changes in the effects indicated by NMAs. Many factors including marketing efforts, regulations, or patient values may have played a role.

CONCLUSION

Enhancements including accelerating CPG updates and monitoring the impact of marketing on prescriptions should be considered in future EBM implementation.

Knowledge translation for the everyday optometrist

A gap exists between best evidence and actual clinical care provided to patients. The advent of evidence-based practice was meant to address this gap by providing practitioners with a method to search, evaluate and incorporate evidence into practice. However, the gap continues to exist. The health research fields of knowledge translation and implementation science have evolved over the last few decades to assist practitioners in embedding research findings and best evidence into routine practice. Knowledge translation seeks to improve public health outcomes by facilitating the movement of best evidence from the bench to clinical practice. Implementation science is the study of methods to integrate research findings and evidence-based practice into routine practice. This literature review aims to revisit the concepts of evidence-based practice and to introduce knowledge translation and implementation science by exploring their roles and influences in the delivery of appropriate glaucoma care by optometrists.

Quality of the Australian National Health and Medical Research Council's clinical practice guidelines for the management of diabetic retinopathy

Clinical relevance: Understanding the quality of the commonly used clinical practice guidelines can help busy clinicians in selecting appropriate guidelines for evidence-based eye care for people with diabetes.Background: The National Health and Medical Research Council's (NHMRC) clinical practice guideline on diabetic retinopathy management has been widely used locally and internationally for over 10 years. However, the quality of this guideline has never been formally assessed. This study aimed to systematically evaluate the quality of the NHMRC guideline and compare it against other international guidelines.Methods: The 2008 NHMRC and another five established diabetic retinopathy management international guidelines (Scottish Intercollegiate Guidelines Network, 2017; American Academy of Ophthalmology, 2019; American Optometric Association, 2019; Royal College of Ophthalmologists, UK, 2013, and Canadian Ophthalmologic Society, 2012) were examined using the Appraisal of Guidelines, Research and Evaluation (AGREE II) instrument. Scoring by four independent reviewers was aggregated into six domain and overall rating scores. Consistency among the reviewers was assessed using intraclass correlation coefficient (ICC).Results: The AGREE II domain scores for the NHMRC guideline were: scope and purpose 72%, stakeholder involvement 64%, rigour of development 77%, clarity of presentation 96%, applicability 35%, and editorial independence 15%. The NHMRC guideline's overall score (5.3 of 7) was lower than that of most other guidelines. Compared to others, the NHMRC guideline scored well in clarity of presentation and rigour of development, but less well for editorial independence. The NHMRC guideline was the least current and a need to update it was recognised by all reviewers who identified key areas for improvement.Conclusion: The quality of the NHMRC guideline was comparable to most other established international guidelines. Several areas of strengths and weaknesses in this guideline were identified. Future updates should aim to improve transparency in development and applicability in clinical practice.

Removing Unnecessary Medical Barriers to Contraception: Celebrating a Decade of the U.S. Medical Eligibility Criteria for Contraceptive Use

In 2010, the Centers for Disease Control and Prevention (CDC) released the U.S. Medical Eligibility Criteria for Contraceptive Use, providing recommendations for health care providers on safe use of contraception for people with certain characteristics or medical conditions. Adapted from World Health Organization guidance, the goal of the recommendations is to remove unnecessary medical barriers to contraception. Over the past decade, CDC has updated recommendations based on new evidence, collaborated with national partners to disseminate and implement the guidelines, and conducted provider surveys to assess changes in attitudes and practices around contraception safety and provision. CDC remains committed to supporting evidence-based guidelines for safe use of contraception, as the basis for improving access to contraception and high-quality family planning services, reducing unintended pregnancy, and improving reproductive health in the United States.

Clinical care of pregnant and postpartum women with COVID-19: Living recommendations from the National COVID-19 Clinical Evidence Taskforce

To date, 18 living recommendations for the clinical care of pregnant and postpartum women with COVID-19 have been issued by the National COVID-19 Clinical Evidence Taskforce. This includes recommendations on mode of birth, delayed umbilical cord clamping, skin-to-skin contact, breastfeeding, rooming-in, antenatal corticosteroids, angiotensin-converting enzyme inhibitors, disease-modifying treatments (including dexamethasone, remdesivir and hydroxychloroquine), venous thromboembolism prophylaxis and advanced respiratory support interventions (prone positioning and extracorporeal membrane oxygenation). Through continuous evidence surveillance, these living recommendations are updated in near real-time to ensure clinicians in Australia have reliable, evidence-based guidelines for clinical decision-making.

Weekly updates of national living evidence-based guidelines: methods for the Australian living guidelines for care of people with COVID-19

Background and Objectives

The Australian National COVID-19 Clinical Evidence Taskforce is a consortium of 31 Australian health professional organisations developing living, evidence-based guidelines for care of people with COVID-19, which are updated weekly. This article describes the methods used to develop and maintain the guidelines.

Methods

The guidelines use the GRADE methods and are designed to meet Australian NHMRC standards. Each week, new evidence is reviewed, current recommendations are revised, and new recommendations made. These are published in MAGIC and disseminated through traditional and social media. Relevant new questions to be addressed are continually sought from stakeholders and practitioners. For prioritized questions, the evidence is actively monitored and updated. Evidence surveillance combines horizon scans and targeted searches. An evidence team appraises and synthesizes evidence and prepares evidence-to-decision frameworks to inform development of recommendations. A guidelines leadership group oversees the development of recommendations by multidisciplinary guidelines panels and is advised by a consumer panel.

Results

: The Taskforce formed in March 2020, and the first recommendations were published 2 weeks later. The guidelines have been revised and republished on a weekly basis for 24 weeks, and as of October 2020, contain over 90 treatment recommendations, suggesting that living methods are feasible in this context.

Conclusions

The Australian guidelines for care of people with COVID-19 provide an example of the feasibility of living guidelines and an opportunity to test and improve living evidence methods.

Clinical guidelines for caring for women with COVID-19 during pregnancy, childbirth and the immediate postpartum period

Background

The spread of the novel coronavirus (COVID-19) was declared a pandemic by the World Health Organization on 11th March 2020. Since then there has been a rapid rise in development of maternal and perinatal health guidelines related to COVID-19. The aim of this project was to develop a database of Australian and international recommendations relating to antenatal, intrapartum and postpartum care of women during the COVID-19 pandemic, in order to identify inconsistencies in clinical guidance.

Methods

We conducted weekly web searches from 30th March to 15th May 2020 to identify recommendations pertaining to the care of women during pregnancy, labour and postpartum period from national or international professional societies, specialist colleges, Ministries of Health, Australian state and territory governments, and international guideline development organisations. Individual recommendations were extracted and classified according to intervention type, time period, and patient population. Findings were reported using descriptive analysis, with areas of consensus and non-consensus identified.

Results

We identified 81 guidelines from 48 different organisations. Generally, there was high consensus across guidelines for specific interventions. However, variable guidance was identified on the use of nitrous oxide during labour, administration of antenatal corticosteroids, neonatal isolation after birth, labour and birth companions, and the use of disease modifying agents for treating COVID-19.

Conclusion

Discrepancies between different guideline development organisations creates challenges for maternity care clinicians during the COVID-19 pandemic. Collating recommendations and keeping up-to-date with the latest guidance can help clinicians provide the best possible care to pregnant women and their babies.

Cost-effectiveness of uterine tamponade devices for the treatment of postpartum hemorrhage: A systematic review

Background

Uterine tamponade is widely promoted for treating refractory postpartum hemorrhage (PPH); however, its cost‐effectiveness may vary depending on unit costs and setting.

Objective

To review available data on cost‐effectiveness of uterine tamponade devices when used for PPH treatment.

Search strategy

PubMed and EMBASE were searched (1980 to January 2020), as well as the National Health Services Economic Evaluation database from inception (1995) to March 2015.

Selection criteria

Eligible studies were any type of economic evaluation, or effectiveness studies that provided cost or economic data.

Data collection and analysis

Two reviewers independently screened studies, extracted data, and assessed quality.

Main results

Eleven studies using a range of devices (condom catheter, uterine suction devices, Bakri, Inpress, Ellavi) were identified. Cost of condom catheter devices or kits ranged from US$0.64 to US$6, whereas purpose‐designed device costs were up to US$400. Two studies that took a health system perspective assessed the cost‐effectiveness of using uterine balloon tamponade and suggested that it was highly cost‐effective because of the low cost per disability‐adjusted life‐year averted, although both used effect estimates from case series.

Conclusions

Evidence on the cost‐effectiveness of uterine tamponade devices was limited and not generalizable. Rigorous economic evaluations based on updated effect estimates are needed.

The lived experience of women with a high-risk pregnancy: A phenomenology investigation

BACKGROUND

Pregnancy is a time of transformation, hope, expectation, and worry for women and their families - none more so than when the pregnancy is at-risk. The objective of this study was to describe the lived experience of women during high-risk pregnancy.

METHODS

This qualitative investigation utilized a hermeneutic phenomenology study. The study was conducted in a public health center in a large urban area in southeast Iran. Purposive sampling of 20 women with a high-risk pregnancy. Participants included both nulligravid and multigravid women in the second and third trimesters of pregnancy with varied medical conditions. Data collection used face-to-face interview with transcribed data analyzed using Braun and Clarke's six stage thematic analysis approach.

RESULTS

Four themes were extracted and included challenge of family in high-risk pregnancy, challenge of anticipation for motherhood, and challenges for future pregnancies, and challenge of adaptation.

CONCLUSIONS

Findings demonstrate that women with a high-risk pregnancy struggle to adapt with burdens related to successful maternal role attainment and family functioning. Fears about pregnancy outcome and future pregnancies are dominant.
