Building capacity for network meta-analysis in Sub-Saharan Africa: reflections and future direction

Robust, relevant, comprehensive, and up-to-date evidence syntheses are the cornerstone for evidence-informed healthcare decisions. When considering multiple treatment options, network meta-analysis (NMA) systematic reviews play a key role in informing impactful decisions and clinical practice guidelines. However, the capacity and literacy to conduct NMA systematic reviews and interpret its results remains out of reach for many clinicians and review authors, especially in low-to-middle-income countries. Despite ample resources and guides, NMA capacity and training opportunities remain limited to non-existent in Sub-Saharan Africa. Towards solutions and strengthening evidence synthesis and NMA capacity in the Sub-Saharan African region, we describe and reflect on two courses that build NMA capacity and aim to address NMA literacy in Sub-Saharan Africa.The Primer in NMA systematic reviews aimed for participants to be able to find, appraise, interpret, and consider the use of NMA SRs of intervention effects. It is a 6-week online course for clinicians, policy-makers, and researchers wanting to learn more about using NMA systematic reviews. The Global NMA Masterclass workshop aimed for participants to be able to understand and apply pairwise and NMA in STATA and R, evaluate NMA assumptions and confidence in NMA results, and appropriately report NMA results. This course was offered over 5 weeks to clinicians, biostatisticians, and researchers with basic knowledge of epidemiology and biostatics. Although the bulk of learning occurred through self-study, we had weekly, synchronous question-and-answer sessions for both courses. Using relevant examples throughout the courses helped to enable an authentic learning environment.This was the first NMA training developed in Africa for Africa. Development of the courses was a collaborative effort from a multi-disciplinary team. Both NMA courses were well received and attended by a diverse group of participants spread across Sub-Saharan African countries. Participants felt the courses were applicable to their setting. Although most participants appreciated the benefits of online learning, we also experienced some challenges. There is great potential to conduct NMA systematic reviews in Sub-Saharan Africa. The NMA Primer and NMA workshop can play an essential role in expanding and developing NMA SR capacity and literacy in SSA.

Quality of systematic reviews in African emergency medicine: a cross-sectional methodological study

Introduction

Reliable systematic reviews are essential to inform clinical practice guidelines, policies and further research priorities in Africa. For systematic review findings to be trustworthy, they need to be conducted with methodological rigour and reported transparently. We assessed the methodological quality of systematic reviews published in African emergency medicine journals, comparing them to those published in international emergency medicine journals. Additionally, we describe the types of review literature published in the African journals.

Methods

We performed a cross-sectional methodological study of systematic reviews published in selected African and international emergency medicine journals from 2012 to 2021. Studies were eligible if they were i) a systematic review on an emergency medicine topic, ii) published in one of the top five emergency medicine journals in the African region or internationally and iii) published between January 2012 and December 2021 in English or French. We searched PubMed, Web of Science and Scopus databases and hand-searched selected journals. Two authors screened titles, abstracts and full texts independently and in duplicate. Data extraction was performed by one reviewer, using a standardised form, after completing a calibration exercise. We described the characteristics of systematic reviews and assessed methodological quality using AMSTAR II.

Results

We identified 34 (37%) African and 511 (54%) international systematic reviews from 92 and 948 review articles respectively across 10 journals. We included all 34 African and a random sample of 100 international systematic reviews. Methodological quality was low or critically low for all the African systematic reviews (n=34, 100%) and all but three international systematic reviews (n=97, 97%). The median number of critical domain weaknesses was 4 (IQR 4;5) and 2 (IQR 2;4) for African and international systematic reviews respectively. The most common weaknesses across both African and international systematic reviews were i) not establishing a priori review protocols, ii) unclear selection of study designs iii) not providing a list of excluded studies and iv) unclear reporting on funding sources for included studies.

Conclusion

Emergency medicine systematic reviews published in African and international journals are lacking in methodological quality. Reporting an a priori protocol, developing a comprehensive search strategy, appropriate evidence synthesis and adequate assessment of risk of bias, heterogeneity and evidence certainty may improve the quality of systematic reviews.

Mapping Effectiveness Studies of Occupational Therapy in Africa: A Scoping Review

Background

Contextual relevance is an important consideration for evidence-based practice, especially in low- and middle-income countries where the nature of practice may differ from high-income countries. Resources and access to rehabilitation are constrained, and service-users face a range of intersecting challenges to activity and participation.

Aim

To evaluate the body of evidence for the effectiveness of occupational therapy in Africa, and to determine if systematic reviews with meta-analysis and/or meta-synthesis are feasible. Methods and Analysis. We conducted a systematic scoping review of published and grey literature by following PRISMA-ScR guidelines across 13 databases and through personal contact with occupational therapists across Africa. Covidence software was used to manage a blind review process by at least three reviewers per included article. The McMaster Quantitative Review Form, NHMRC levels of evidence, the Cochrane PROGRESS-Plus health equity criteria, and the TIDieR checklist informed data extraction using Microsoft Forms.

Results

The search yielded 4199 articles, of which 45 were included. Evidence in six fields of practice included paediatrics, mental health, physical rehabilitation, hand therapy, work practice, and community development, although the evidence was largely limited to South Africa (93% studies). Levels of evidence varied but included 13 RCTs. In all, 1957 participants were included, ranging in age from 25 days to 99 years, with a wide range of health conditions. Most studies reported a positive outcome for occupational therapy.

Conclusion

Findings suggest a moderate body of evidence to support occupational therapy in Africa. Systematic review with meta-analysis, assessment of risk of bias, and in-depth analysis of specific areas of practice are now required. All effectiveness studies in occupational therapy should include measures of occupational performance or participation, minimum reporting standard checklists should be used more consistently, and effect sizes should be consistently calculated and reported in effectiveness research.

The effects on clinical trial activity of direct funding and taxation policy interventions made by government: A systematic review

Context

Governments have attempted to increase clinical trial activity in their jurisdictions using a range of methods including targeted direct funding and industry tax rebates. The effectiveness of the different approaches employed is unclear.

Objective

To systematically review the effects of direct government financing interventions by allowing companies to reduce their tax payable on clinical trial activity.

Data sources

Pub Med, Scopus, Sage, ProQuest, Google Scholar and Google were searched up to the 11th of April 2022. In addition, the reference lists of all potentially eligible documents were hand searched to identify additional reports. Following feedback from co-authors, information on a small number of additional interventions were specifically sought out and included.

Data extraction

Summary information about potentially eligible reports were reviewed independently by two researchers, followed by extraction of data into a structured spreadsheet for eligible studies. The primary outcomes of interest were the number of clinical trials and the expenditure on clinical trials but data about other evaluations were also collected.

Results

There were 1694 potentially eligible reports that were reviewed. Full text assessments were done for 304, and 30 reports that provided data on 43 interventions were included– 29 that deployed targeted direct funding and 14 that provided tax rebates or exemptions. There were data describing effects on a primary outcome for 25/41 of the interventions. The most common types of interventions were direct funding to researchers via special granting mechanisms and tax offsets to companies and research organisations. All 25 of the studies for which data were available reported a positive impact on numbers and/or expenditure on clinical trials though the robustness of evaluations was limited for many. Estimates of the magnitude of effects of interventions were reported inconsistently, varied substantially, and could not be synthesised quantitatively, though targeted direct funding interventions appeared to be associated with more immediate impact on clinical trial activity.

Conclusion

There is a high likelihood that governments can increase clinical trial activity with either direct or indirect fiscal mechanisms. Direct funding may provide a more immediate and tangible return on investment than tax rebates.

Characteristics of knowledge translation platforms and methods for evaluating them: a scoping review protocol

INTRODUCTION

Knowledge translation platforms (KTPs) are intermediary organisations, initiatives or networks whose intent is to bridge the evidence into action divide. Strategies and tools include collaborative knowledge production, capacity building, information exchange and dialogue to facilitate relevant and timely engagement between researchers and decision-makers and other relevant stakeholders. With the wide range of definitions and descriptions of KTPs, there is a need to (1) provide a nuanced understanding of characteristics of KTPs and (2) assess and consolidate research methods used in mapping and evaluating KTPs to inform standardised process and impact evaluation.

METHODS AND ANALYSIS

This scoping review will follow the recommended and accepted methods for scoping reviews and reporting guidelines. Eligibility for inclusion is any conceptual or empirical health-related qualitative, quantitative and/or mixed method studies including (1) definitions, descriptions and models or frameworks of KTPs (including those that do not self-identify as KTPs, eg, university research centres) and (2) research methods for mapping and/or evaluating KTPs. Searches will be carried out in PubMed, Scopus, CINAHL, Embase, Global Health and Web of Science using a predetermined search strategy, without any date, language or geographical restrictions. Two reviewers will independently screen titles and abstracts. One reviewer will complete data extraction for all included studies, and another will check a sample of 50% of the included studies. The analysis and synthesis will provide (1) an understanding of the various characteristics of KTPs; (2) insight into characteristics or factors that make them resilient and/or adaptive to facilitate impact (ie, influence policy and practice); and (3) an overview of the various methods for mapping and evaluating KTPs. We will explore enhancing an existing framework for classifying KTPs, or perhaps even developing a new framework for identifying and monitoring KTPs if necessary and relevant.

ETHICS AND DISSEMINATION

This scoping review does not require ethics approval, as we will only include information from previously conducted studies and we will not involve human participants. The results will be submitted to a peer-reviewed scientific journal for publication and as conference presentations.

Self-reported knowledge, attitudes, practices and barriers in use of evidence-based medicine among resident physicians in Kenya: a mixed methods study

BACKGROUND

Evidence based medicine (EBM) helps clinicians to integrate latest research evidence into their daily clinical practice. There is a need for all healthcare professions to adopt it in order to provide safe and most cost-effective care. Postgraduate doctors are at the frontline of healthcare delivery and all medical institutions should strive to produce practitioners of EBM. Studies have shown that physicians are still struggling to adapt to this paradigm shift in the practice of medicine but very few studies have been done in Sub Saharan Africa. This study explored the self-reported knowledge, attitudes, practices and barriers of evidence-based practice among resident physicians in a tertiary teaching hospital.

METHODS

A mixed methods cross-sectional study that used convergent parallel design was conducted. The quantitative arm was conducted among all residents enrolled in the Master of Medicine programme at Aga Khan University Hospital Nairobi (AKUHN). It included an online survey exploring self-reported knowledge, attitudes, practices and barriers of EBM among all residents. Simultaneously, semi-structured In-Depth Interviews were carried out among 18 purposefully selected residents in order to explore the same themes in more depth.

RESULTS

One hundred and one residents (99%) responded to the survey. The mean scores for self-reported knowledge, attitude and practice of EBM among residents were 73.88, 66.96 and 63.19% respectively, which were generally higher than in comparable studies. There was a significant association between year of residency and practice of EBM. The most common barriers faced by residents were lack of time, lack of EBM skills and patients' unawareness about EBM. From the qualitative study, residents demonstrated good knowledge and support of EBM but practice remained relatively poor. Barriers to EBM were characterized by lack of motivation, time, skills and resources, patient overload and fear of challenging consultants.

CONCLUSION

There was good understanding and support of EBM among residents at AKUHN, though challenges were experienced in regards to practice of EBM because of lack of time and skills. Therefore resources should be allocated towards integrating EBM into undergraduate medical curricula to cultivate critical thinking skills at an early stage before transition into residency.

Evidence synthesis workshops: moving from face-to-face to online learning

Postgraduate training is moving from face-to-face workshops or courses to online learning to help increase access to knowledge, expertise and skills, and save the cost of face-to-face training. However, moving from face-to-face to online learning for many of us academics is intimidating, and appears even more difficult without the help of a team of technologists. In this paper, we describe our approach, our experiences and the lessons we learnt from converting a Primer in Systematic Reviews face-to-face workshop to a 6-week online course designed for healthcare professionals in Africa. We learnt that the team needs a balance of skills and experience, including technical know-how and content knowledge; that the learning strategies needed to achieve the learning objectives must match the content delivery. The online approach should result in both building knowledge and developing skills, and include interactive and participatory approaches. Finally, the design and delivery needs to keep in mind the limited and expensive internet access in some resource-poor settings in Africa.

Advancing collaborations in health research and clinical trials in Sub-Saharan Africa: development and implementation of a biostatistical collaboration module in the Masters in Biostatistics Program at Stellenbosch University

Background

Sub-Saharan Africa continues to carry a high burden of communicable diseases such as TB and HIV and non-communicable diseases such as hypertension and other cardiovascular conditions. Although investment in research has led to advances in improvements in outcomes, a lot still remains to be done to build research capacity in health. Like many other regions in the world, Sub-Saharan Africa suffers from a critical shortage of biostatisticians and clinical trial methodologists.

Methods

Funded through a Fogarty Global Health Training Program grant, the Faculty of Medicine and Health Sciences at Stellenbosch University in South Africa established a new Masters Program in Biostatistics which was launched in January 2017. In this paper, we describe the development of a biostatistical and clinical trials collaboration Module, adapted from a similar course offered in the Health Research Methodology program at McMaster University.

Discussion

Guided by three core principles (experiential learning; multi-/inter-disciplinary approach; and formal mentorship), the Module aims to advance biostatistical collaboration skills of the trainees by facilitating learning in how to systematically apply fundamental statistical and trial methodological knowledge in practice while strengthening some soft skills which are necessary for effective collaborations with other healthcare researchers to solve health problems. We also share some preliminary findings from the first four cohorts that took the Module in January–November 2018 to 2021. We expect that this Module can provide an example of how to improve biostatistical and clinical trial collaborations and accelerate research capacity building in low-resource settings.

Strengthening prehospital clinical practice guideline development in South Africa: Reflections from guideline experts

INTRODUCTION

De novo (new) guideline development methods are well described and supported by numerous examples, including comprehensive checklists. However, alternative guideline development methods, which draw from existing up to date, high quality clinical practice guidelines instead of re-inventing the wheel, have not been adopted so readily, despite the potential efficiencies of such methods compared to de novo development. In Africa, guideline quality and rigour of development, especially for prehospital care, remains poor. This paper firstly describes the opinions of international guideline experts on the African Federation for Emergency Medicine guideline project, and secondly updates a framework for South African prehospital guideline development.

METHODS

We conducted a qualitative study of expert reviews of an evidence-based guideline development project led by the African Federation for Emergency Medicine in 2016 for prehospital care in South Africa. We purposefully sampled key international and regional guideline experts from a range of organisations. Comments and voice memos, following a terms of reference guide, were thematically analysed through manual coding.

RESULTS

A total of seven experts gave feedback. Key themes revolved around existing international clinical practice guidelines not being enough to cover context specific evidence, blurring of guideline responsibilities and output, and transparency of guideline decisions and conflicts of interest. We showcase three fit-for-purpose guideline development approaches and provide an updated alternative guideline development roadmap for low-resource settings.

CONCLUSION

In order to create clinical practice guidelines that clinicians trust and use on a daily basis to change lives, guideline developers need rigorous yet pragmatic approaches that are responsive to end-user needs. Reflecting on the African Federation for Emergency Medicine prehospital guideline development project in 2016, this paper presents key guiding themes to strengthen guideline development in low- and middle-income countries and other low-resource settings and provides an updated hybrid guideline development approach.

Guidance we can trust? The status and quality of prehospital clinical guidance in sub-Saharan Africa: A scoping review

INTRODUCTION

Prehospital care is integral in addressing sub-Saharan Africa's (SSA) high injury and illness burden. Consequently, robust, high-quality prehospital guidance documents are needed to inform care. These guidance documents include, but are not limited to, clinical practice guidelines (CPGs), protocols and algorithms that are contextually appropriate for SSA. However, SSA prehospital guidance mostly originates from the 'Global North,' with limited guidance for Africa by Africans. To strengthen prehospital clinical practice in SSA, we described and appraised all prehospital SSA guidance documents informing clinical decision making.

METHODS

We conducted a scoping review of prehospital-relevant guidance documents, including CPGs, algorithms, protocols and position statements originating from SSA. We performed a comprehensive literature search in various databases (PUBMED and SCOPUS), guideline clearing houses (Scottish Intercollegiate Guidelines Network, Trip, and Guidelines International Network), journals, various forms of grey literature and contacted experts. Guidance document screening and data extraction was done independently, in duplicate and reviewed by a third author. Guidance quality was then determined using the AGREE II tool and data were analysed using simple descriptive statistics.

RESULTS

We included 51 guidance documents from 13 countries across SSA after screening 2320 potential documents. The majority of guidance documents lacked an evidence foundation, made recommendations based on expert input, and were predominantly end-user presentations such as algorithms or protocols. Overall, reporting quality was poor, specifically for critical domains such as rigour of development; however, clarity of presentation was generally strong. Guidance topics were focused around resuscitation and common diseases (both communicable and non-communicable) with major gaps identified across a variety of topics; such as mental health for example.

CONCLUSION

The majority of prehospital clinical guidance from SSA provides clinicians with excellent ready to use end-user material. Conversely, most of the guidance documents lack an appropriate evidence foundation and fail to transparently report the guidance development process, highlighting the need to strengthen and build guideline development capacity to promote the transition from eminence-based to evidence-based guidance for prehospital care in SSA. Guideline developers, professional societies and publishers need to be aware of international and local guidance document development and reporting standards in order to produce guidance we can trust.

Clinical practice guideline adaptation methods in resource-constrained settings: four case studies from South Africa

Developing a clinical practice guideline (CPG) is expensive and time-consuming and therefore often unrealistic in settings with limited funding or resources. Although CPGs form the cornerstone of providing synthesised, systematic, evidence-based guidance to patients, healthcare practitioners and managers, there is no added benefit in developing new CPGs when there are accessible, good-quality, up-to-date CPGs available that can be adapted to fit local needs. Different approaches to CPG development have been proposed, including adopting, adapting or contextualising existing high-quality CPGs to make recommendations relevant to local contexts. These approaches are attractive where technical and financial resources are limited and high-quality guidance already exists. However, few examples exist to showcase such alternative approaches to CPG development. The South African Guidelines Excellence project held a workshop in 2017 to provide an opportunity for dialogue regarding different approaches to guideline development with key examples and case studies from the South African setting. Four CPGs represented the topics: mental health, health promotion, chronic musculoskeletal pain and prehospital emergency care. Each CPG used a different approach, however, using transparent, reportable methods. They included advisory groups with representation from content experts, CPG users and methodologists. They assessed CPGs and systematic reviews for adopting or adapting. Each team considered local context issues through qualitative research or stakeholder engagement. Lessons learnt include that South Africa needs fit-for-purpose guidelines and that existing appropriate, high-quality guidelines must be taken into account. Approaches for adapting guidelines are not clear globally and there are lessons to be learnt from existing descriptions of approaches from South Africa.

Figuring it out by yourself: Perceptions of home-based care of stroke survivors, family caregivers and community health workers in a low-resourced setting, South Africa

BACKGROUND

In less resourced settings, formal rehabilitation services for stroke survivors were often absent. Stroke survivors were referred to community health workers (CHWs) who were untrained in rehabilitation.

AIM

To describe the experience and perceived needs of stroke survivors, their caregivers and CHWs in a context with limited access to and support from formal rehabilitation services.

SETTING

The Breede Valley subdistrict, Western Cape, South Africa, a rural, less resourced setting.

METHODS

A descriptive exploratory qualitative study. Four focus group interviews were held with purposively selected stroke survivors and caregivers and four with CHWs. A thematic approach and the framework method were used to analyse the transcripts.

FINDINGS

A total of 41 CHWs, 21 caregivers and 26 stroke survivors participated. Four main themes and 11 sub-themes were identified. Because of the lack of knowledge, training and rehabilitation services, the main theme for all groups was having to 'figure things out' independently, with incontinence management being particularly challenging. Secondly was the need for emotional support for stroke survivors and caregivers. Thirdly, contextual factors such as architectural barriers and lack of assistive products negatively impacted care and function. Lastly, the organisation of health and rehabilitation services negatively impacted home-based services and professional support.

CONCLUSIONS

With appropriate training, the CHWs can be pivotal in the training and support of family caregivers and stroke survivors. Care pathways and the role and scope of both CHWs and therapists in home-based stroke rehabilitation should be defined and restructured, including the links with formal services.

Enhancing capacity for clinical practice guidelines in South Africa

INTRODUCTION

Use of good quality, evidence-informed and up-to-date clinical practice guidelines (CPGs) has the potential to impact health outcomes. This paper describes the development, implementation and evaluation of a dedicated CPG training course to address the training needs of CPG stakeholders in South Africa.

METHODS

We first reviewed the content and teaching strategies of existing CPG courses. This review consisted of a systematic review of teaching and learning strategies for guideline teams and a document review of existing courses offered by international guideline groups, universities and professional groups. We then strengthened an existing CPG course and evaluated it.

RESULTS

We found no studies on teaching and learning strategies for guideline teams. We identified six CPG courses being offered as full courses (part of a postgraduate degree program) by universities or as independent training for continuing professional education by professional groups. Contents focused on new guideline development. One course included alternative methods of guideline approaches such as contextualization and adaptation. The format varied from face-to-face sessions, to online sessions, group exercises and discussions, seminar format and project based activities. The revised CPG four-month long course that we implemented was designed to be pragmatic, reflective and contextually relevant. It used local guideline examples, authentic tasks, and an online forum for discussions and resources. It covered de novo CPG development, alternative methods of development (adopting, contextualising, adapting), and implementing CPGs. Course evaluation identified strengths and areas for improvement.

CONCLUSION

Dedicated capacity development has potential to positively influence CPG development and implementation.

Strengthening prehospital clinical practice guideline implementation in South Africa: a qualitative case study

BACKGROUND

Methods on developing new (de novo) clinical practice guidelines (CPGs) have received substantial attention. However, research into alternative methods of CPG development using existing CPG documents (CPG adaptation) - a specific issue for guideline development groups in low- and middle-income countries - is sparse. There are only a few examples showcasing the pragmatic application of such alternative approaches in settings with time and budget constraints, especially in the prehospital setting. This paper aims to describe and strengthen the methods of developing prehospital CPGs using alternative guideline development methods through a case study design.

METHODS

We qualitatively explored a CPG development project conducted in 2016 for prehospital providers in South Africa as a case study. Key stakeholders, involved in various processes of the guideline project, were purposefully sampled. Data were collected from one focus group and six in-depth interviews and analysed using thematic analysis. Overarching themes and sub-themes were inductively developed and categorised as challenges and recommendations and further transformed into action points.

RESULTS

Key challenges revolved around guideline implementation as opposed to development. These included the unavoidable effect of interest and beliefs on implementing recommendations, the local evidence void, a shifting implementation context, and opposing end-user needs. Guideline development and implementation strengthening priority actions included: i) developing a national end-user document; ii) aligning recommendations with local practice; iii) communicating a clear and consistent message; iv) addressing controversial recommendations; v) managing the impact of interests, beliefs and intellectual conflicts; and vi) transparently reporting implementation decisions.

CONCLUSION

The cornerstone of a successful guideline development process is the translation and implementation of CPG recommendations into clinical practice. We highlight key priority actions for prehospital guideline development teams with limited resources to strengthen guideline development, dissemination, and implementation by drawing from lessons learnt from a prehospital guideline project conducted in South Africa.

Barriers and Facilitators to Implementing Evidence in African Health Care: A Content Analysis With Implications for Action

BACKGROUND

Culture- and context-specific issues in African countries such as those related to language, resources, technology, infrastructure and access to available research may confound evidence implementation efforts. Understanding the factors that support or inhibit the implementation of strategies aimed at improving care and health outcomes specific to their context is important.

AIMS

The aim of this study was to determine barriers and facilitators to evidence implementation in African healthcare settings, based on implementation projects undertaken as part of the Joanna Briggs Institute (JBI) Clinical Fellowship program.

METHODS

Reports of implementation projects conducted in Africa were obtained from the JBI database and printed monographs associated with the fellowship program. A purpose-built data extraction form was used to collect data from individual reports. Data were analysed using content analysis.

RESULTS

Eleven published and nine unpublished implementation reports were reviewed. The most frequently reported barriers to evidence implementation operate at the health organization or health practitioner level. Health organization-level barriers relate to human resources, material resources and policy issues. Health practitioner-level barriers relate to practitioners' knowledge and skills around evidence-based practice, and attitudes to change. Barriers at the government and consumer levels were uncommon. Only a few facilitators were identified and were related to health practitioners' attitudes or support from the organization's management.

LINKING EVIDENCE TO ACTION

The study identified a core set of barriers and facilitators in African healthcare settings, which are common to other low- and middle-income countries. These can be used to develop a method by which implementation programs can systematically undertake barrier or facilitator analysis. Future research should aim to develop a process by which these barriers and facilitators can be prioritised so that a structured decision support procedure can be established.

Developing prehospital clinical practice guidelines for resource limited settings: why re-invent the wheel?

OBJECTIVES

Methods on developing new (de novo) clinical practice guidelines (CPGs) have received substantial attention. However, the volume of literature is not matched by research into alternative methods of CPG development using existing CPG documents-a specific issue for guideline development groups in low- and middle-income countries. We report on how we developed a context specific prehospital CPG using an alternative guideline development method. Difficulties experienced and lessons learnt in applying existing global guidelines' recommendations to a national context are highlighted.

RESULTS

The project produced the first emergency care CPG for prehospital providers in Africa. It included > 270 CPGs and produced over 1000 recommendations for prehospital emergency care. We encountered various difficulties, including (1) applicability issues: few pre-hospital CPGs applicable to Africa, (2) evidence synthesis: heterogeneous levels of evidence classifications and (3) guideline quality. Learning points included (1) focusing on key CPGs and evidence mapping, (2) searching other resources for CPGs, (3) broad representation on CPG advisory boards and (4) transparency and knowledge translation. Re-inventing the wheel to produce CPGs is not always feasible. We hope this paper will encourage further projects to use existing CPGs in developing guidance to improve patient care in resource-limited settings.
