Policy strategies for capacity building and scale up of the workforce for comprehensive cancer care: a systematic review

BACKGROUND

Patients with cancer in low- and middle-income countries experience worse outcomes as a result of the limited capacity of health systems to deliver comprehensive cancer care. The health workforce is a key component of health systems; however, deep gaps exist in the availability and accessibility of cancer care providers.

MATERIALS AND METHODS

We carried out a systematic review of the literature evaluating the strategies for capacity building of the cancer workforce. We studied how the policy strategies addressed the availability, accessibility, acceptability, and quality (AAAQ) of the workforce. We used a strategic planning framework (SWOT: strengths, weaknesses, opportunities, threats) to identify actionable areas of capacity building. We contextualized our findings based on the WHO 2030 Global Strategy on Human Resources for Health, evaluating how they can ultimately be framed in a labour market approach and inform strategies to improve the capacity of the workforce (PROSPERO: CRD42020109377).

RESULTS

The systematic review of the literature yielded 9617 records, and we selected 45 eligible papers for data extraction. The workforce interventions identified were delivered mostly in the African and American Regions, and in two-thirds of cases, in high-income countries. Many strategies have been shown to increase the number of competent oncology providers. Optimization of the existing workforce through role delegation and digital health interventions was reported as a short- to mid-term solution to optimize cancer care, through quality-oriented, efficiency-improving, and acceptability-enforcing workforce strategies. The increased workload alone was potentially detrimental. The literature on retaining the workforce and reducing brain drain or attrition in underserved areas was commonly limited.

CONCLUSIONS

Workforce capacity building is not only a quantitative problem but can also be addressed through quality-oriented, organizational, and managerial solutions of human resources. The delivery of comprehensive, acceptable, and impact-oriented cancer care requires an available, accessible, and competent workforce for comprehensive cancer care. Efficiency-improving strategies may be instrumental for capacity building in resource-constrained settings.

Enhancing surgical oncology in Sub-Saharan Africa through international cooperation

Cancer burden is rising in sub- Saharan Africa. Surgery is the best option for the treatment of solid tumors, both for oncologic results and cost-effectiveness. A surgical system to deliver safe, quick and affordable treatment options is not available. High income countries models for cancer care are not applicable in SSA especially in rural settings. Afro-centric models are needed, and the Surgical oncologist should be the heart of this system. Local surgeons must be trained in surgical oncology to develop a tailored surgical system for the setting they are operating in. Education and Training should be supported by international collaborations with high income countries.

Surgical Capacity in Rural Southeast Nigeria: Barriers and New Opportunities

Background:

Remarkable gains have been made in global health with respect to provision of essential and emergency surgical and anesthesia care. At the same time, little has been written about the state of surgical care, or the potential strategies for scale-up of surgical services in sub-Saharan Africa, southeast Nigeria inclusive.

Objective:

The aim was to document the state of surgical care at district hospitals in southeast Nigeria.

Methods:

We surveyed 13 district hospitals using the World Health Organization (WHO) tool for situational analysis developed by the “Lancet Commission on Global Surgery” initiative to assess surgical care in rural Southeast Nigeria. A systematic literature review of scientific literatures and policy documents was performed. Extraction was performed for all articles relating to the five National Surgical, Obstetric and Anesthesia Plans (NSOAPs) domains: infrastructure, service delivery, workforce, information management and financing.

Findings:

Of the 13 facilities investigated, there were six private, four mission and three public hospitals. Though all the facilities were connected to the national power grid, all equally suffered electricity interruption ranging from 10–22 hours daily. Only 15.4% and 38.5% of the 13 hospitals had running water and blood bank services, respectively. Only two general surgeon and two orthopedic surgeons covered all the facilities. Though most of the general surgical procedures were performed in private and mission hospitals, the majority of the public hospitals had limited ability to do the same. Orthopedic procedures were practically non-existent in public hospitals. None of the facilities offered inhalational anesthetic technique. There was no designated record unit in 53.8% of facilities and 69.2% had no trained health record officer.

Conclusion:

Important deficits were observed in infrastructure, service delivery, workforce and information management. There were indirect indices of gross inadequacies in financing as well.

The State of Surgical Task Sharing for Inguinal Hernia Repair in Limited-Resource Countries

BACKGROUND

In limited-resource countries, the morbidity and mortality related to inguinal hernias is unacceptably high. This review addresses the issue by identifying capacity-building education of non-surgeons performing inguinal hernia repairs in developing countries and analyzing the outcomes.

METHODS

PubMed was searched and included are studies that reported on task sharing and surgical outcomes for inguinal hernia surgery. Educational methods with quantitative and qualitative effects of the capacity-building methods have been recorded. Excluded were papers without records of outcome data.

RESULTS

Seven studies from African countries reported 14,108 elective inguinal hernia repairs performed by 230 non-surgeons with a mortality rate of 0.36%. Complications were reported in 4 of the 7 studies with a morbidity rate of 14.2%. Two studies reported on follow-up: one with no recurrences in 408 patients at 7.4 months and the other one with 0.9% recurrences in 119 patients at 12 months. Direct comparison of outcomes from trained non-surgeons to surgeons or surgically trained medical doctors is limited but suggests no difference in outcomes. Quantitative capacity-building effects include increase in surgical workforce, case volume, elective procedures, mesh utilization, and decreased referrals to higher level of care institutions. Qualitative capacity-building effects include feasibility of prospective research in limited-resource settings, improved access to surgical care, and change in practice pattern of local physicians after training for mesh repair.

CONCLUSION

Systematic training of non-surgeons in inguinal hernia repair is potentially a high-impact capacity-building strategy. High-risk patients should be referred to a fully trained surgeon whenever possible. Randomized study designs and long-term outcomes beyond 1 year are needed.

A systematic review and meta-analysis of valued obstetric and gynecologic (OB/GYN) procedures in resource-poor areas

Background

Obstetric and gynecologic procedures are valuable in rural settings. Data identifying common procedures may better prepare surgeons to meet patient needs in remote settings.

Materials and methods

A literature review using key MeSH terms was performed according to methods described by the Cochrane Collaboration and PRISMA on studies that described obstetric and gynecologic surgery in rural high-income countries or any setting in middle- to low-income countries. Meta-analysis was performed using random effects modeling for odds ratios of cesarean delivery and hysterectomy as proportions of total surgical volume.

Results

A total of 195 studies were included for qualitative synthesis and 22 for quantitative analysis. Obstetric and gynecologic procedures made up a 19% of all surgical cases. As compared to other obstetric and gynecologic surgical procedures, cesarean delivery was the most common procedure with odds ratio of 2.39 (95% confidence interval 1.48–3.86), and hysterectomy was the second most common procedure with odds ratio of 1.60 (1.57–1.64). However, heterogeneity between the studies was extremely high and risk of bias was high, limiting quality of findings.

Conclusion

Greater provision of surgical care can be enhanced by defining which procedures are most needed, which include many obstetric and gynecologic procedures, most commonly cesarean delivery and hysterectomy.

Evaluation of a surgical training programme for clinical officers in Malawi

BACKGROUND

Shortages of specialist surgeons in African countries mean that the needs of rural populations go unmet. Task-shifting from surgical specialists to other cadres of clinicians occurs in some countries, but without widespread acceptance. Clinical Officer Surgical Training in Africa (COST-Africa) developed and implemented BSc surgical training for clinical officers in Malawi.

METHODS

Trainees participated in the COST-Africa BSc training programme between 2013 and 2016. This prospective study done in 16 hospitals compared crude numbers of selected numbers of major surgical procedures between intervention and control sites before and after the intervention. Volume and outcomes of surgery were compared within intervention hospitals between the COST-Africa trainees and other surgically active cadres.

RESULTS

Seventeen trainees participated in the COST-Africa BSc training. The volume of surgical procedures undertaken at intervention hospitals almost doubled between 2013 and 2015 (+74 per cent), and there was a slight reduction in the number of procedures done in the control hospitals (-4 per cent) (P = 0·059). In the intervention hospitals, general surgery procedures were more often undertaken by COST-Africa trainees (61·2 per cent) than other clinical officers (31·3 per cent) and medical doctors (7·4 per cent). There was no significant difference in postoperative wound infection rates for hernia procedures at intervention hospitals between trainees and medical doctors (P = 0·065).

CONCLUSION

The COST-Africa study demonstrated that in-service training of practising clinical officers can improve the surgical productivity of district-level hospitals.

Development of a novel Global Trauma System Evaluation Tool and initial results of implementation in the Republic of South Sudan

INTRODUCTION

Trauma remains a leading cause of death and disability in the world, and trauma systems decrease mortality from trauma. We developed the Global Trauma System Evaluation Tool (G-TSET) specifically for use in low- and middle-income countries (LMICs). The Sudan People's Liberation Army (SPLA) in the Republic of South Sudan (RSS) desires a military trauma system (MTS) which allowed us to pilot the G-TSET.

METHODS

The G-TSET was developed by modifying key components of a trauma system applicable to LMICs. We partnered with the SPLA Medical Corps using clinical collaboration, direct observation, and discussion groups. Benchmarks and indicators were scored with 5 indicating "full capability" and 1 meaning "not present" and were used to develop a SPLA MTS plan.

RESULTS

The overall MTS score was 1.15 indicating an urgent need for system development. The assessment highlighted the need for SPLA Command support. Battlefield care, transport to a trauma facility, and inter-facility communication were identified for improvement. After essential battlefield care, consisting primarily of bandaging and splinting, transport times for injured SPLA soldiers were 12h to 3 days by truck. Based on our findings, we collaborated with SPLA medical leadership to develop a plan to develop a formal MTS.

CONCLUSION

We piloted a novel trauma system assessment tool for the MTS in the RSS. Qualitatively, we identified gaps in the MTS and provided the medical leadership with a plan for improvement. We anticipate a short-term follow-up to quantify improvement, and we seek to validate this tool for use in other countries.

Short-term medical service trips: a systematic review of the evidence

Short-term medical service trips (MSTs) aim to address unmet health care needs of low- and middle-income countries. The lack of critically reviewed empirical evidence of activities and outcomes is a concern. Developing evidence-based recommendations for health care delivery requires systematic research review. I focused on MST publications with empirical results. Searches in May 2013 identified 67 studies published since 1993, only 6% of the published articles on the topic in the past 20 years. Nearly 80% reported on surgical trips. Although the MST field is growing, its medical literature lags behind, with nearly all of the scholarly publications lacking significant data collection. By incorporating data collection into service trips, groups can validate practices and provide information about areas needing improvement.

Neonatal anesthesia with limited resources

Neonates are the most vulnerable age group in terms of anesthetic risk and perioperative mortality, especially in the developing world. Prematurity, malnutrition, delays in presentation, and sepsis contribute to this risk. Lack of healthcare workers, poorly maintained equipment, limited drug supplies, absence of postoperative intensive care, unreliable water supplies, or electricity are further contributory factors. Trained anesthesiologists with the skills required for pediatric and neonatal anesthesia as well as basic monitoring equipment such as pulse oximetry will go a long way to improve the unacceptably high anesthetic mortality.

Surgical Care in the Developing World-Strategies and Framework for Improvement

The purpose of this study was to identify the various problems with surgical care in the developing world and enumerate identified strategies or propose solutions. We also sought to rank these strategies in order of potential impact. The MEDLINE database was sought. Studies published in English, reporting currently employed solutions to identified barriers or problems to surgical care in developing countries or potential solution(s) and published between 2000 and 2012 were eligible for inclusion. 2156 articles were identified for possible inclusion. MeSH terms include surgery, general surgery, developing countries, health services accessibility and quality improvement. Forty-nine full articles with a primary focus on the solutions to the challenges to surgical care in the developing world were included in the final review. Many articles identified problems with infrastructure, workforce shortage, inadequate or inappropriate policies, and poor financing as major problems with healthcare in the developing world. Solutions addressing these problems are multifactorial and would require active participation of local authorities and collaboration with providers from the developed world. The burden of surgical care is increasing. There is poor access to surgical services in the developing world. If and when surgical care is received, the quality could be less than the standard in developed nations. Solutions exist to tackle these problems but require a multidimensional approach to be successful.

Global disease burden of conditions requiring emergency surgery

BACKGROUND

Surgical disease is inadequately addressed globally, and emergency conditions requiring surgery contribute substantially to the global disease burden.

METHODS

This was a review of studies that contributed to define the population-based health burden of emergency surgical conditions (excluding trauma and obstetrics) and the status of available capacity to address this burden. Further data were retrieved from the Global Burden of Disease Study 2010 and the University of Washington's Institute for Health Metrics and Evaluation online data.

RESULTS

In the index year of 2010, there were 896,000 deaths, 20 million years of life lost and 25 million disability-adjusted life-years from 11 emergency general surgical conditions reported individually in the Global Burden of Disease Study. The most common cause of death was complicated peptic ulcer disease, followed by aortic aneurysm, bowel obstruction, biliary disease, mesenteric ischaemia, peripheral vascular disease, abscess and soft tissue infections, and appendicitis. The mortality rate was higher in high-income countries (HICs) than in low- and middle-income countries (LMICs) (24.3 versus 10.6 deaths per 100,000 inhabitants respectively), primarily owing to a higher rate of vascular disease in HICs. However, because of the much larger population, 70 per cent of deaths occurred in LMICs. Deaths from vascular disease rose from 15 to 25 per cent of surgical emergency-related deaths in LMICs (from 1990 to 2010). Surgical capacity to address this burden is suboptimal in LMICs, with fewer than one operating theatre per 100,000 inhabitants in many LMICs, whereas some HICs have more than 14 per 100,000 inhabitants.

CONCLUSION

The global burden of surgical emergencies is described insufficiently. The bare estimates indicate a tremendous health burden. LMICs carry the majority of emergency conditions; in these countries the pattern of surgical disease is changing and capacity to deal with the problem is inadequate. The data presented in this study will be useful for both the surgical and public health communities to plan a more adequate response.

Primary surgery in rural areas of southern Sudan

BACKGROUND

We report through a retrospective analysis our experience of providing surgical care and on-the-job training through mobile surgical missions in southern Sudan during the post conflict period between 2005 and 2009.

METHODS

Three surgical teams conducted 23 missions in 5 primary health care centers sited in remote areas of southern Sudan. King's analytical framework for surgical care in developing countries is adopted to evaluate the appropriateness of services rendered. Exact logistic regression was performed to investigate differences in mortality depending on the level of training of the operators and anesthetists.

RESULTS

A total of 1,543 patients were operated on during a 5 year period, of which 9 (0.58%) died. The majority of operations were elective surgery cases (which may help contextualize the exceptionally low mortality rate). Several adaptations to surgical techniques adopted and preoperative and postoperative care were required. There were no statistically significant differences in mortality between operations performed by expatriate specialists and local midlevel providers with lower level training.

CONCLUSIONS

This experience in southern Sudan demonstrates that surgical services can be established utilizing simple facilities and equipment and employing local personnel selected and trained on-the-job by teams composed of a consultant surgeon, anesthetist, and scrub nurse. Delegation of tasks relating to anesthesia and surgery to midlevel health providers is an appropriate approach in developing countries facing shortage and maldistribution of more qualified health workers.

Plea for greater use of spinal anaesthesia in developing countries

When it is indicated for surgical procedures below the umbilicus in our low-resource countries, spinal anaesthesia has many advantages: it is simple, cheap, safe and easy to learn and carry out. It reduces nursing load and the risk of aspiration pneumonitis as well as overall postoperative mortality and morbidity. We prospectively carried out a study of 419 patients operated under spinal anaesthesia during our normal surgical activities. Despite the materials and conditions that were not always those recommended in the published literature, we had very satisfactory results with: (1) a high patient acceptance rate (93.9%); (2) relatively rare adverse effects - the most frequent being hypotension and vomiting each observed in seven (1.67%) patients. We had two cases (0.48%) of the rare cauda equina syndrome. In poor-resource countries, the culture of spinal anaesthesia should be better developed and encouraged by the training institutions.

Emergency, anaesthetic and essential surgical capacity in the Gambia

OBJECTIVE

To assess the resources for essential and emergency surgical care in the Gambia.

METHODS

The World Health Organization's Tool for Situation Analysis to Assess Emergency and Essential Surgical Care was distributed to health-care managers in facilities throughout the country. The survey was completed by 65 health facilities - one tertiary referral hospital, 7 district/general hospitals, 46 health centres and 11 private health facilities - and included 110 questions divided into four sections: (i) infrastructure, type of facility, population served and material resources; (ii) human resources; (iii) management of emergency and other surgical interventions; (iv) emergency equipment and supplies for resuscitation. Questionnaire data were complemented by interviews with health facility staff, Ministry of Health officials and representatives of nongovernmental organizations.

FINDINGS

Important deficits were identified in infrastructure, human resources, availability of essential supplies and ability to perform trauma, obstetric and general surgical procedures. Of the 18 facilities expected to perform surgical procedures, 50.0% had interruptions in water supply and 55.6% in electricity. Only 38.9% of facilities had a surgeon and only 16.7% had a physician anaesthetist. All facilities had limited ability to perform basic trauma and general surgical procedures. Of public facilities, 54.5% could not perform laparotomy and 58.3% could not repair a hernia. Only 25.0% of them could manage an open fracture and 41.7% could perform an emergency procedure for an obstructed airway.

CONCLUSION

The present survey of health-care facilities in the Gambia suggests that major gaps exist in the physical and human resources needed to carry out basic life-saving surgical interventions.

Anaesthesia in haemodynamically compromised emergency patients: does ketamine represent the best choice of induction agent?

In rapid sequence induction of anaesthesia in the emergency setting in shocked or hypotensive patients (e.g. ruptured abdominal aortic aneurysm, polytrauma or septic shock), prior resuscitation is often suboptimal and comorbidities (particularly cardiovascular) may be extensive. The induction agents with the most favourable pharmacological properties conferring haemodynamic stability appear to be ketamine and etomidate. However, etomidate has been withdrawn from use in some countries and impairs steroidogenesis. Ketamine has been traditionally contra-indicated in the presence of brain injury, but we argue in this review that any adverse effects of the drug on intracranial pressure or cerebral blood flow are in fact attenuated or reversed by controlled ventilation, subsequent anaesthesia and the greater general haemodynamic stability conferred by the drug. Ketamine represents a very rational choice for rapid sequence induction in haemodynamically compromised patients.

Pediatric anesthesia in developing countries

PURPOSE OF REVIEW

To highlight the problems faced in developing countries where healthcare resources are limited, with particular emphasis on pediatric anesthesia.

RECENT FINDINGS

The fact that very few publications address pediatric anesthesia in the developing world is not surprising given that most anesthetics are provided by nonphysicians, nurses or unqualified personnel. In compiling this article information is drawn from pediatric surgical, anesthetic and related texts. In a recent survey more than 80% of anesthesia providers in a poor country acknowledged that with the limited resources available they could not provide basic anesthesia for children less than 5 years. Although many publications could be regarded as anecdotal, the similarities to this survey suggest that the lack of facilities is more generalized than we would like to believe.

SUMMARY

The real risk of anesthesia in comparison to other major health risks such as human immunodeficiency virus, malaria, tuberculosis and trauma remains undetermined. The critical shortage of manpower remains a barrier to progress. Despite erratic electrical supplies, inconsistent oxygen delivery, paucity of drugs or equipment and on occasion even lack of running water, many provide life-saving anesthesia. Perioperative morbidity and mortality is, however, understandably high by developed world standards.
