The contribution of non-physician clinicians to the provision of surgery in rural Zambia-a randomised controlled trial

Exploring barriers and enabling factors for surgical task sharing with physician assistants in Liberia: a qualitative pre-implementation study

OBJECTIVES

This study explores potential barriers and enabling factors that may influence the acceptance of implementation of a surgical task-sharing initiative targeting physician assistants (PAs) in Liberia.

DESIGN

A qualitative, pre-implementation study using semistructured interviews. Data was analysed in NVivo V.12 using deductive coding and the consolidated framework for implementation research as a guide.

SETTING

Liberia has few surgical providers and a poor surgical infrastructure resulting in a very low surgical volume. The research was conducted in the context of an already running surgical task-sharing programme for midwives.

PARTICIPANTS

In 2019, a total of 30 key stakeholders in the field of surgery and the PAs training programme were interviewed.

RESULTS

The majority of the stakeholders supported the idea of training PAs in surgery. The high unemployment rate among PAs and the need for career advancement of this cadre were important enabling factors. Resistance against surgical task sharing for mid-level clinicians is multifaceted. The Ministry of Health (MOH) did not share a common vision. Opponents within the MOH believed budgetary constraints within the MOH and the lack of surgical infrastructure is a more pressing problem compared with the surgically trained human resources. Another important group of opponents are medical officers (MOs) and their professional bodies. Many of their negative beliefs around surgical task sharing reflect lessons to be drawn from the current surgical training programme for midwives.

CONCLUSION

Prior to deciding on implementation of a surgical training programme for PAs, wider support is needed. If surgical task sharing with PAs is to be considered, the intervention should focus on adapting the 'adaptable' periphery of the intervention to broaden the support of the MOH, MOs and their professional bodies. Failing to obtain such support should make the implementors consider alternative strategies to strengthen surgical human resources in rural Liberia.

Professional care workforce: a rapid review of evidence supporting methods of recruitment, retention, safety, and education

BACKGROUND

Across the care economy there are major shortages in the health and care workforce, as well as high rates of attrition and ill-defined career pathways. The aim of this study was to evaluate current evidence regarding methods to improve care worker recruitment, retention, safety, and education, for the professional care workforce.

METHODS

A rapid review of comparative interventions designed to recruit, retain, educate and care for the professional workforce in the following sectors: disability, aged care, health, mental health, family and youth services, and early childhood education and care was conducted. Embase and MEDLINE databases were searched, and studies published between January 2015 and November 2022 were included. We used the Quality Assessment tool for Quantitative Studies and the PEDro tools to evaluate study quality.

RESULTS

5594 articles were initially screened and after applying the inclusion and exclusion criteria, 30 studies were included in the rapid review. Studies most frequently reported on the professional nursing, medical and allied health workforces. Some studies focused on the single domain of care worker education (n = 11) while most focused on multiple domains that combined education with recruitment strategies, retention strategies or a focus on worker safety. Study quality was comparatively low with a median PEDro score of 5/10, and 77% received a weak rating on the Quality Assessment tool for Quantitative Studies. Four new workforce strategies emerged; early career rural recruitment supports rural retention; workload management is essential for workforce well-being; learning must be contextually relevant; and there is a need to differentiate recruitment, retention, and education strategies for different professional health and care workforce categories as needs vary.

CONCLUSIONS

Given the critical importance of recruiting and retaining a strong health and care workforce, there is an immediate need to develop a cohesive strategy to address workforce shortfalls. This paper presents initial evidence on different interventions to address this need, and to inform care workforce recruitment and retention.

Task Shifting and Task Sharing to Strengthen the Surgical Workforce in Sub-Saharan Africa: A Systematic Review of the Existing Literature

BACKGROUND

A major constraint to surgical care delivery in low-resource settings is inadequate workforce availability. Surgical task shifting (TShifting) and task sharing (TSharing), in which non-surgeon clinicians (NSCs) are trained to perform select surgical procedures, have been proposed as one solution. However, patterns of safety and efficacy of surgical TShifting/TSharing are not well-established. This study aims to summarize the current literature and assess clinical outcomes and impact of surgical TShifting/TSharing in sub-Saharan Africa.

METHODS

A two-tiered systematic, PRISMA-adherent literature review of surgical TShifting/TSharing in sub-Saharan Africa was conducted. Collected data included healthcare settings; types of surgeries performed; attitudes toward NSCs; and categories, training, capacity, clinical outcomes, safety, retention, cost-effectiveness, and supervision of NSCs. A random effects meta-analysis of morbidity and mortality rates between NSCs and surgeons was conducted.

RESULTS

Among the 659 abstracts screened, 31 studies met inclusion criteria and were integrated in the final analysis. Eighteen studies (58%) report on the capacity and aptitude of NSCs, 16 (52%) on clinical outcomes and safety, and seven (23%) on attitudes. NSCs performed 1999 (61%) of 3304 total surgical cases studied. The most common operations reported were hernia repair (n = 12, 57%), acute abdominal (n = 12, 57%), and orthopedic procedures (n = 6, 29%). No differences were found between NSC and surgeon case morbidity [315 (16%) vs. 224 (17%); p > 0.05] and mortality [44 (2.2%) vs. 33 (2.5%); p > 0.05] rates.

CONCLUSION

NSCs are increasingly performing surgical tasks in regions of sub-Saharan Africa deficient in trained surgeons and appear to have non-inferior safety outcomes in select programs.

Assessing the impact of anaesthetic and surgical task-shifting globally: a systematic literature review

The global shortage of skilled anaesthesiologists, surgeons and obstetricians is a leading cause of high unmet surgical need. Although anaesthetic and surgical task-shifting are widely practised to mitigate this barrier, little is known about their safety and efficacy. This systematic review seeks to highlight the existing evidence on the clinical outcomes of patients operated on by non-physicians or non-specialist physicians globally. Relevant articles were identified by searching four databases (MEDLINE, EMBASE, CINAHL and Global Health) in all languages between January 2008 and February 2022. Retrieved documents were screened against pre-specified inclusion and exclusion criteria, and their qualities were appraised critically. Data were extracted by two independent reviewers and findings were synthesized narratively. In total, 40 studies have been included. Thirty-five focus on task-shifting for surgical and obstetric procedures, whereas four studies address anaesthetic task-shifting; one study covers both interventions. The majority are located in sub-Saharan Africa and the USA. Seventy-five per cent present perioperative mortality outcomes and 85% analyse morbidity measures. Evidence from low- and middle-income countries, which primarily concentrates on caesarean sections, hernia repairs and surgical male circumcisions, points to the overall safety of non-surgeons. On the other hand, the literature on surgical task-shifting in high-income countries (HICs) is limited to nine studies analysing tube thoracostomies, neurosurgical procedures, caesarean sections, male circumcisions and basal cell carcinoma excisions. Finally, only five studies pertaining to anaesthetic task-shifting across all country settings answer the research question with conflicting results, making it difficult to draw conclusions on the quality of non-physician anaesthetic care. Overall, it appears that non-specialists can safely perform high-volume, low-complexity operations. Further research is needed to understand the implications of surgical task-shifting in HICs and to better assess the performance of non-specialist anaesthesia providers. Future studies must adopt randomized study designs and include long-term outcome measures to generate high-quality evidence.

Using participatory action research to empower district hospital staff to deliver quality-assured essential surgery to rural populations in Malawi, Zambia, and Tanzania

Background

In 2017 the SURG-Africa project set out to institute a surgical, obstetric, trauma and anesthesia (SOTA) care capacity-building intervention focused on non-specialist providers at district hospitals in Zambia, Malawi and Tanzania. The aim was to scale up quality-assured SOTA care for rural populations. This paper reports the process of developing the intervention and our experience of initial implementation, using a participatory approach.

Methods

Participatory Action Research workshops were held in the 3 countries in July-October 2017 and in October 2018-July 2019, involving representatives of key local stakeholder groups: district hospital (DH) surgical teams and administrators, referral hospital SOTA specialists, professional associations and local authorities. Through semi-structured discussions, qualitative data were collected on participants' perceptions and experiences of barriers to the provision of SOTA care at district level, and on the training and supervision needs of district surgical teams. Data were compared for themes across countries and across surgical team cadres.

Results

All groups reported a lack of in-service training to develop essential skills to manage common SOTA cases; use and care of equipment; essential anesthesia care including resuscitation skills; and infection prevention and control. Very few district surgical teams had access to supervision. SOTA providers at DHs reported a demand for more feedback on referrals. Participants prioritized training needs that could be addressed through regular in-service training and supervision visits from referral hospital specialists to DHs. These data were used by participants in an action-planning cycle to develop site-specific training plans for each research site.

Conclusion

The inclusive, participatory approach to stakeholder involvement in SOTA system strengthening employed by this study supported the design of a locally relevant and contextualized intervention. This study provides lessons on how to rebalance power dynamics in Global Surgery, through giving a voice to district surgical teams.

Critical shortage of capacity to deliver safe paediatric surgery in sub-Saharan Africa: evidence from 67 hospitals in Malawi, Zambia, and Tanzania

Introduction

Paediatric surgical care is a significant challenge in Sub-Saharan Africa (SSA), where 42% of the population are children. Building paediatric surgical capacity to meet SSA country needs is a priority. This study aimed to assess district hospital paediatric surgical capacity in three countries: Malawi, Tanzania and Zambia (MTZ).

Methods

Data from 67 district-level hospitals in MTZ were collected using a PediPIPES survey tool. Its five components are procedures, personnel, infrastructure, equipment, and supplies. A PediPIPES Index was calculated for each country, and a two-tailed analysis of variance test was used to explore cross-country comparisons.

Results

Similar paediatric surgical capacity index scores and shortages were observed across countries, greater in Malawi and less in Tanzania. Almost all hospitals reported the capacity to perform common minor surgical procedures and less complex resuscitation interventions. Capacity to undertake common abdominal, orthopaedic and urogenital procedures varied-more often reported in Malawi and less often in Tanzania. There were no paediatric or general surgeons or anaesthesiologists at district hospitals. General medical officers with some training to do surgery on children were present (more often in Zambia). Paediatric surgical equipment and supplies were poor in all three countries. Malawi district hospitals had the poorest supply of electricity and water.

Conclusions

With no specialists in district hospitals in MTZ, access to safe paediatric surgery is compromised, aggravated by shortages of infrastructure, equipment and supplies. Significant investments are required to address these shortfalls. SSA countries need to define what procedures are appropriate to national, referral and district hospital levels and ensure that an appropriate paediatric surgical workforce is in place at district hospitals, trained and supervised to undertake these essential surgical procedures so as to meet population needs.

Task shifting cesarean sections in low- and middle-income countries: A systematic review and meta-analysis

BACKGROUND

Safe and timely access to cesarean section (CS) in low- and middle-income countries (LMIC) remains a significant challenge.

OBJECTIVES

To compare maternal and perinatal outcomes of CS by non-physician clinicians (NPCs) versus physicians in LMIC.

SEARCH STRATEGY AND SELECTION CRITERIA

A systematic search of Ovid MEDLINE, EMBASE, Cochrane Library (including CENTRAL), Web of Science, and LILACS was performed from inception to January 2022.

DATA COLLECTION AND ANALYSIS

Data were extracted by two independent reviewers and meta-analysis was performed when possible.

MAIN RESULTS

Ten studies from seven African countries were included. There was no significant difference in maternal mortality for CS performed by NPCs versus physicians (odds ratio [OR] 1.09, 95% confidence interval [CI] 0.56-2.14, P = 0.8, I²  = 70%, P < 0.05, eight studies, n = 20 711) or in perinatal mortality (OR 1.18, 95% CI 0.86-1.61, P = 0.3, I²  = 88%, n = 19 716). Despite heterogeneous clinical settings between providers, there was no difference in the rates of wound infection or re-operation, although there was a higher rate of wound complications (such as dehiscence) in the NPC group (OR 1.89, 95% CI 1.21-2.95, P = 0.005, n = 6507).

CONCLUSIONS

NPCs have comparable maternal and neonatal outcomes for CS compared with standard providers, albeit with increased odds of wound complication.

Emergency medicine physician supervision and mortality among patients receiving care from non-physician clinicians in a task-sharing model of emergency care in rural Uganda: a retrospective analysis of a single-centre training programme

OBJECTIVES

To assess the association between emergency medicine physician supervision and 3-day mortality for patients receiving care from non-physician clinicians in a task-sharing model of emergency care in rural Uganda.

DESIGN

Retrospective cohort analysis with multivariable logistic regression.

SETTING

Single rural Ugandan emergency unit.

PARTICIPANTS

All patients presenting for care from 2009 to 2019.

INTERVENTIONS

Three cohorts of patients receiving care from non-physician clinicians had three different levels of physician supervision: 'Direct Supervision' (2009-2010) emergency medicine physicians directly supervised all care; 'Indirect Supervision' (2010-2015) emergency medicine physicians were consulted as needed; 'Independent Care' (2015-2019) no emergency medicine physician supervision.

PRIMARY OUTCOME MEASURE

Three-day mortality.

RESULTS

38 033 ED visits met inclusion criteria. Overall mortality decreased significantly across supervision cohorts ('Direct' 3.8%, 'Indirect' 3.3%, 'Independent' 2.6%, p<0.001), but so too did the rates of patients who presented with ≥3 abnormal vitals ('Direct' 32%, 'Indirect' 19%, 'Independent' 13%, p<0.001). After controlling for vital sign abnormalities, 'Direct' and 'Indirect' supervision were both significantly associated with reduced OR for mortality ('Direct': 0.57 (0.37 to 0.90), 'Indirect': 0.71 (0.55 to 0.92)) when compared with 'Independent Care'. Sensitivity analysis showed that this mortality benefit was significant for the minority of patients (17.2%) with ≥3 abnormal vitals ('Direct': 0.44 (0.22 to 0.85), 'Indirect': 0.60 (0.41 to 0.88)), but not for the majority (82.8%) with two or fewer abnormal vitals ('Direct': 0.81 (0.44 to 1.49), 'Indirect': 0.82 (0.58 to 1.16)).

CONCLUSIONS

Emergency medicine physician supervision of emergency care non-physician clinicians is independently associated with reduced overall mortality. This benefit appears restricted to the highest risk patients based on abnormal vitals. With over 80% of patients having equivalent mortality outcomes with independent non-physician clinician emergency care, a synergistic model providing variable levels of emergency medicine physician supervision or care based on patient acuity could safely address staffing shortages.

A thematic review of the use of electronic logbooks for surgical assessment in sub-Saharan Africa

INTRODUCTION

Ensuring that surgical training programmes in low- and middle-income countries (LMICs) provide high quality training, including adequate operative experience, is of crucial importance in meeting the goals set out in the Lancet Global Surgery 2030. Electronic logbooks (eLogbooks) have been adopted to monitor both individual trainee progression and the performance of surgical training programmes.

METHODS

We performed a thematic review of the current evidence base surrounding the use of eLogbooks for the assessment of surgeons in training in sub-Saharan Africa, with a view to identifying the learning to date and areas for future research.

RESULTS

Whilst there are multiple papers highlighting the use of surgical eLogbooks in high-income countries, we identified only three papers which discussed their use in sub-Saharan Africa. Four common themes emerged which related to the use of surgical eLogbooks throughout sub-Saharan Africa: ease of analysis, centralised databases, discrepancies in reporting and technology limitations.

CONCLUSIONS

Robust data to demonstrate trainee progression and the quality of surgical training programmes are of crucial importance in ensuring that surgical training programmes can rapidly scale up to deliver large numbers of well-trained surgical providers to address the unmet patient need in LMICs in the next decade. The limited data on the use of well designed, centralised electronic surgical logbooks indicate that this tool may play an important role in providing key data to underpin these training programmes.

Policy options for surgical mentoring: Lessons from Zambia based on stakeholder consultation and systems science

BACKGROUND

Supervision by surgical specialists is beneficial because they can impart skills to district hospital-level surgical teams. The SURG-Africa project in Zambia comprises a mentoring trial in selected districts, involving two provincial-level mentoring teams. The aim of this paper is to explore policy options for embedding such surgical mentoring in existing policy structures through a participatory modeling approach.

METHODS

Four group model building workshops were held, two each in district and central hospitals. Participants worked in a variety of institutions and had clinical and/or administrative backgrounds. Two independent reviewers compared the causal loop diagrams (CLDs) that resulted from these workshops in a pairwise fashion to construct an integrated CLD. Graph theory was used to analyze the integrated CLD, and dynamic system behavior was explored using the Method to Analyse Relations between Variables using Enriched Loops (MARVEL) method.

RESULTS

The establishment of a provincial mentoring faculty, in collaboration with key stakeholders, would be a necessary step to coordinate and sustain surgical mentoring and to monitor district-level surgical performance. Quarterly surgical mentoring reviews at the provincial level are recommended to evaluate and, if needed, adapt mentoring. District hospital administrators need to closely monitor mentee motivation.

CONCLUSIONS

Surgical mentoring can play a key role in scaling up district-level surgery but its implementation is complex and requires designated provincial level coordination and regular contact with relevant stakeholders.

Surgical service monitoring and quality control systems at district hospitals in Malawi, Tanzania and Zambia: a mixed-methods study

BACKGROUND

In low-income and middle-income countries, an estimated one in three clinical adverse events happens in non-complex situations and 83% are preventable. Poor quality of care also leads to inefficient use of human, material and financial resources for health. Improving outcomes and mitigating the risk of adverse events require effective monitoring and quality control systems.

AIM

To assess the state of surgical monitoring and quality control systems at district hospitals (DHs) in Malawi, Tanzania and Zambia.

METHODS

A mixed-methods cross-sectional study of 75 DHs: Malawi (22), Tanzania (30) and Zambia (23). This included a questionnaire, interviews and visual inspection of operating theatre (OT) registers. Data were collected on monitoring and quality systems for surgical activity, processes and outcomes, as well as perceived barriers.

RESULTS

53% (n=40/75) of DHs use more than one OT register to record surgical operations. With the exception of standardised printed OT registers in Zambia, the register format (often handwritten books) and type of data collected varied between DHs. Monthly reports were seldom analysed by surgical teams. Less than 30% of all surveyed DHs used surgical safety checklists (n=22/75), and <15% (n=11/75) performed surgical audits. 73% (n=22/30) of DHs in Tanzania and less than half of DHs in Malawi (n=11/22) and Zambia (n=10/23) conducted surgical case reviews. Reports of surgical morbidity and mortality were compiled in 65% (n=15/23) of Zambian DHs, and in less than one-third of DHs in Tanzania (n=9/30) and Malawi (n=4/22). Reported barriers to monitoring and quality systems included an absence of formalised guidelines, continuous training opportunities as well as inadequate accountability mechanisms.

CONCLUSIONS

Surgical monitoring and quality control systems were not standard among sampled DHs. Improvements are needed in standardisation of quality measures used; and in ensuring data completeness, analysis and utilisation for improving patient outcomes.

Barriers to surgery performed by non-physician clinicians in sub-Saharan Africa-a scoping review

BACKGROUND

Sub-Saharan Africa (SSA) faces the highest burden of disease amenable to surgery while having the lowest surgeon to population ratio in the world. Some 25 SSA countries use surgical task-shifting from physicians to non-physician clinicians (NPCs) as a strategy to increase access to surgery. While many studies have investigated barriers to access to surgical services, there is a dearth of studies that examine the barriers to shifting of surgical tasks to, and the delivery of safe essential surgical care by NPCs, especially in rural areas of SSA. This study aims to identify those barriers and how they vary between surgical disciplines as well as between countries.

METHODS

We performed a scoping review of articles published between 2000 and 2018, listed in PubMed or Embase. Full-text articles were read by two reviewers to identify barriers to surgical task-shifting. Cited barriers were counted and categorized, partly based on the World Health Organization (WHO) health systems building blocks.

RESULTS

Sixty-two articles met the inclusion criteria, and 14 clusters of barriers were identified, which were assigned to four main categories: primary outcomes, NPC workforce, regulation, and environment and resources. Malawi, Tanzania, Uganda, and Mozambique had the largest number of articles reporting barriers, with Uganda reporting the largest variety of barriers from empirical studies only. Obstetric and gynaecologic surgery had more articles and cited barriers than other specialties.

CONCLUSION

A multitude of factors hampers the provision of surgery by NPCs across SSA. The two main issues are surgical pre-requisites and the need for regulatory and professional frameworks to legitimate and control the surgical practice of NPCs.

Supervision as a tool for building surgical capacity of district hospitals: the case of Zambia

INTRODUCTION

Many countries in sub-Saharan Africa have adopted task shifting of surgical responsibilities to non-physician clinicians (NPCs) as a solution to address workforce shortages. There is resistance to delegating surgical procedures to NPCs due to concerns about their surgical skills and lack of supervision systems to ensure safety and quality of care provided. This study aimed to explore the effects of a new supervision model implemented in Zambia to improve the delivery of health services by surgical NPCs working at district hospitals.

METHODS

Twenty-eight semi-structured interviews were conducted with NPCs and medical doctors at nine district hospitals and with the surgical specialists who provided in-person and remote supervision over an average period of 15 months. Data were analysed using 'top-down' and 'bottom-up' thematic coding.

RESULTS

Interviewees reported an improvement in the surgical skills and confidence of NPCs, as well as better teamwork. At the facility level, supervision led to an increase in the volume and range of surgical procedures done and helped to reduce unnecessary surgical referrals. The supervision also improved communication links by facilitating the establishment of a remote consultation network, which enabled specialists to provide real-time support to district NPCs in how to undertake particular surgical procedures and expert guidance on referral decisions. Despite these benefits, shortages of operating theatre support staff, lack of equipment and unreliable power supply impeded maximum utilisation of supervision.

CONCLUSION

This supervision model demonstrated the additional role that specialist surgeons can play, bringing their expertise to rural populations, where such surgical competence would otherwise be unobtainable. Further research is needed to establish the cost-effectiveness of the supervision model; the opportunity costs from surgical specialists being away from referral hospitals, providing supervision in districts; and the steps needed for regular district surgical supervision to become part of sustainable national programmes.

Developing the health workforce for universal health coverage

Optimizing the management of the health workforce is necessary for the progressive realization of universal health coverage. Here we discuss the six main action fields in health workforce management as identified by the Human Resources for Health Action Framework: leadership; finance; policy; education; partnership; and human resources management systems. We also identify and describe examples of effective practices in the development of the health workforce, highlighting the breadth of issues that policy-makers and planners should consider. Achieving success in these action fields is not possible by pursuing them in isolation. Rather, they are interlinked functions that depend on a strong capacity for effective stewardship of health workforce policy. This stewardship capacity can be best understood as a pyramid of tools and factors that encompass the individual, organizational, institutional and health system levels, with each level depending on capacity at the level below and enabling actions at the level above. We focus on action fields covered by the organizational or system-wide levels that relate to health workforce development. We consider that an analysis of the policy and governance environment and of mechanisms for health workforce policy development and implementation is required, and should guide the identification of the most relevant and appropriate levels and interventions to strengthen the capacity of health workforce stewardship and leadership. Although these action fields are relevant in all countries, there are no best practices that can simply be replicated across countries and each country must design its own responses to the challenges raised by these fields.
