Protocol for a scoping review of work system design in health care.

BACKGROUND: Delivery of safe and reliable healthcare to patients and the healthcare workforce shortage amidst growing demand has been major challenge to the healthcare system. Addressing this challenge calls for designing or redesigning of healthcare work system. Work system design which is usually associated with productivity in manufacturing offers a wide spectrum of applicability in addressing this challenge of healthcare system. Despite the availability of primary studies on work system design in healthcare, there are sparse published reviews in specific contexts. This scoping review explores the existing evidence to understand the state of the art of work system design in healthcare. METHODS: The scoping review adopts the methodology of Joanna Briggs Institute for scoping review which is based on the methodological framework of Arksey and O'Malley. The search will be done on PubMed, Scopus, and Web of Science for the identification of eligible studies. A grey literature search will also be performed. A two-phase screening and extraction of data will be done by two independent reviewers. Data extraction will be done on a pre-piloted data extraction form. The findings will be presented in tables, figures, and a narrative summary. The scoping review will highlight the state of the art, gaps in knowledge and provide directions for future research. ETHICS AND DISSEMINATION: This is a scoping review of primary studies and therefore ethical approval is not required. The report of the findings will be presented in line with the PRISMA reporting guidelines for scoping reviews (PRISMA-ScR). The results will be submitted to a peer-reviewed scientific journal for publication and presented at relevant conferences.

Spatial diarrheal disease risks and antibiogram diversity of diarrheagenic Escherichia coli in selected access points of the Buffalo River, South Africa.

Freshwater sources, often used for domestic and agricultural purposes in low- and middle-income countries are repositories of clinically significant bacterial pathogens. These pathogens are usually diversified in their antibiogram profiles posing public health threats. This study evaluated the spatial diarrhoeal disease risk and antibiogram diversity of diarrheagenic Escherichia coli (DEC) in four access points of the Buffalo River, Eastern Cape Province, South Africa using standard epidemiological, culture, and molecular methods. The diarrhoeal disease risk was characterised using the Monte Carlo simulation, while the antibiogram diversity was assessed using the species observed Whittaker's single alpha-diversity modelling. E. coli mean count was highest in King William's Town dam [16.0 × 102 CFU/100ml (SD: 100.0, 95% CI: 13.5 × 102 to 18.5 × 102)]. Enterohemorrhagic E. coli (stx1/stx2) was the most prevalent DEC pathotype across the study sites. A high diarrhoeal disease risk of 25.0 ×10-2 exceeding the World Health Organization's standard was recorded across the study sites. The average single and multiple antimicrobial resistance indices of the DEC to test antimicrobials were highest in the Eluxolzweni dam [0.52 (SD: 0.25, 95% CI: 0.37 to 0.67)] and King William's Town dam [0.42 (SD: 0.25, 95% CI: 0.27 to 0.57)] respectively. The prevalent antibiotic resistance genes detected were tetA, blaFOX and blaMOX plasmid-mediated AmpC, blaTEM and blaSHV extended-spectrum ß-lactamases, which co-occurred across the study sites on network analysis. The phenotypic and genotypic resistance characteristics of the DEC in Maden dam (r = 0.93, p<0.00), Rooikrantz dam (r = 0.91, p<0.00), King William's Town dam (r = 0.83, p = 0.0), and Eluxolzweni dam (r = 0.91, p<0.00) were strongly correlated. At least, three phylogenetic clades of the DEC with initial steep descent alpha-diversity curves for most of the test antimicrobials were observed across the study sites, indicating high diversity. The occurrence of diversified multi drug resistant DEC with diarrhoeal disease risks in the Buffalo River substantiates the role surface water bodies play in the dissemination of drug-resistant bacterial pathogens with public health implications.

The use of artificial intelligence for delivery of essential health services across WHO regions: a scoping review.

Background: Artificial intelligence (AI) is a broad outlet of computer science aimed at constructing machines capable of simulating and performing tasks usually done by human beings. The aim of this scoping review is to map existing evidence on the use of AI in the delivery of medical care. Methods: We searched PubMed and Scopus in March 2022, screened identified records for eligibility, assessed full texts of potentially eligible publications, and extracted data from included studies in duplicate, resolving differences through discussion, arbitration, and consensus. We then conducted a narrative synthesis of extracted data. Results: Several AI methods have been used to detect, diagnose, classify, manage, treat, and monitor the prognosis of various health issues. These AI models have been used in various health conditions, including communicable diseases, non-communicable diseases, and mental health. Conclusions: Presently available evidence shows that AI models, predominantly deep learning, and machine learning, can significantly advance medical care delivery regarding the detection, diagnosis, management, and monitoring the prognosis of different illnesses.

Modelling the Potential Risk of Infection Associated with Listeria monocytogenes in Irrigation Water and Agricultural Soil in Two District Municipalities in South Africa.

Listeria monocytogenes (L. monocytogenes) is the etiologic agent of listeriosis which significantly affects immunocompromised individuals. The potential risk of infection attributed to L. monocytogenes in irrigation water and agricultural soil, which are key transmission pathways of microbial hazards to the human population, was evaluated using the quantitative microbial risk assessment modelling. A Monte Carlo simulation with 10,000 iterations was used to characterize the risks. High counts of L. monocytogenes in irrigation water (mean: 11.96 × 102 CFU/100 mL; range: 0.00 to 56.67 × 102 CFU/100 mL) and agricultural soil samples (mean: 19.64 × 102 CFU/g; range: 1.33 × 102 to 62.33 × 102 CFU/g) were documented. Consequently, a high annual infection risk of 5.50 × 10-2 (0.00 to 48.30 × 10-2), 54.50 × 10-2 (9.10 × 10-3 to 1.00) and 70.50 × 10-2 (3.60 × 10-2 to 1.00) was observed for adults exposed to contaminated irrigation water, adults exposed to contaminated agricultural soil and children exposed to agricultural soil, respectively. This study, therefore, documents a huge public health threat attributed to the high probability of infection in humans exposed to L. monocytogenes in irrigation water and agricultural soil in Amathole and Chris Hani District Municipalities in the Eastern Cape province of South Africa.

The impact of faith-based organizations on maternal and child health care outcomes in Africa: taking stock of research evidence.

This evidence synthesis aimed at assessing the effectiveness of Faith-Based Organisations (FBOs) on Maternal and Child Health (MCH) outcomes; and explore the perceptions and experiences of the users and providers of MCH services delivered by FBOs in Africa. This review considered studies from African countries only. Both reviews and primary studies focusing on MCH services provided by FBOs were considered. Quantitative, qualitative, and mixed methods reviews were included with no restriction on the date and language. Primary outcomes included maternal mortality ratio, neonatal mortality, infant mortality, child mortality, quality of care, views, experiences, and perceptions of users of FBOs. We searched up to November 2020 in the Joanna Briggs Institute (JBI) Database of Systematic Reviews and Implementation Reports, the Cochrane Database of Systematic Reviews, Database of Abstracts of Reviews of Effects, PROSPERO register, PDQ-evidence, Health Systems Evidence, CINAHL, EMBASE, and PubMed. We searched references cited by similar studies that may be potentially eligible for inclusion. We then updated the search for primary studies from December 2009 - October 2020. One systematic review and six primary studies met the eligibility criteria for inclusion. Methodological quality varied. These observational and qualitative studies found that FBOs offered the following MCH services - training of healthcare workers, obstetric services, health promotion, sexual education, immunization services, and intermittent preventive therapy for malaria. Maternal and Child Health (MCH) services provided by FBO suggest a reduction in maternal morbidity and mortality. Increased uptake of maternal healthcare services, and increased satisfaction were reported by users of care. However, costs of providing these services varied across the studies and users. This review shows that FBOs play an important role in improving access and delivery of MCH services and have the potential of strengthening the health system at large. Rigorous research is needed to ascertain the effectiveness of FBO-based interventions in strengthening the health systems in Africa.

Strengthening the Health System as a Strategy to Achieving a Universal Health Coverage in Underprivileged Communities in Africa: A Scoping Review.

Universal health coverage (UHC) is defined as people having access to quality healthcare services (e.g., treatment, rehabilitation, and palliative care) they need, irrespective of their financial status. Access to quality healthcare services continues to be a challenge for many people in low- and middle-income countries (LMICs). The aim of this study was to conduct a scoping review to map out the health system strengthening strategies that can be used to attain universal health coverage in Africa. We conducted a scoping review and qualitatively synthesized existing evidence from studies carried out in Africa. We included studies that reported interventions to strengthen the health system, e.g., financial support, increasing work force, improving leadership capacity in health facilities, and developing and upgrading infrastructure of primary healthcare facilities. Outcome measures included health facility infrastructures, access to medicines, and sources of financial support. A total of 34 studies conducted met our inclusion criteria. Health financing and developing health infrastructure were the most reported interventions toward achieving UHC. Our results suggest that strengthening the health system, namely, through health financing, developing, and improving the health infrastructure, can play an important role in reaching UHC in the African context.

Improving the availability of vaccines in primary healthcare facilities in South Africa: is the time right for a system redesign process?

An uninterrupted supply of vaccines at different supply chain levels is a basic component of a functional immunization programme and care service. There can be no progress toward achieving universal health coverage and sustainable development without continuous availability of essential medicines and vaccines in healthcare facilities. Shortages of vaccines, particularly at health facility level is an issue of grave concern that requires urgent attention in South Africa. The causes of vaccine stock-outs are multifactorial and may be linked to a broader systems issue. These factors include challenges at higher levels such as delays in the delivery of stock from the pharmaceutical depot; health facility level factors, which include a lack of commitment from healthcare workers and managers; human resource factors, such as, staff shortages, and lack of skilled personnel. Therefore, there is a compelling need to address the factors associated with shortages of vaccines in health facilities. This paper highlights the challenges of vaccine availability in South Africa, the associated factors, the available interventions, and recommended interventions for the expanded programme on immunization in South Africa. We propose a system redesign approach as a potentially useful intervention.

Reflection: burden of cervical cancer in Sub-Saharan Africa and progress with HPV vaccination.

In Sub-Saharan (SSA) cervical cancer is the leading cause of cancer deaths amongst women. The region carries the greatest burden, with 24.55% of the global mortality from cervical cancer. Reports indicate an increasing challenge of cervical cancer in SSA. HPV vaccination with its well-established effectiveness provides hope for cancer control in SSA. Following an initial delay in HPV vaccine uptake in SSA, 18 countries mostly in Eastern and Southern Africa, had a national programme by 2020. Vaccination coverage data show that high populated countries have lower coverage figures. Furthermore, high coverage of demonstration projects may not be achieved in the national rollout. In conclusion, whilst there is significant progress with the rollout of HPV vaccination programme in SSA, some countries in West Africa should be prioritised. Experiences of early adopters should be reviewed to guide other countries to achieve and sustain high coverage.

Missed opportunities for vaccination in Africa.

The purpose of this review is to assess the extent of missed opportunities for vaccination (MOV) in Africa, determine the associated factors, and provide recommendations that countries could adopt in reducing MOV. Two databases were searched for multinational studies and systematic reviews reporting MOV and involving African countries. A total of 288 records were identified and 12 studies included for synthesis. The prevalence ranged from 47.0% to 62.1%, with a weighted mean of 27.3%. This review highlighted caregiver utilization, health service delivery, and healthcare worker' factors associated with MOV. Understanding the extent of MOV in Africa presents an opportunity for multiple approaches to resolve the differential factors that contribute to MOV, and to bridge the gap in vaccination coverage in the continent.

Patient safety education for undergraduate nursing students: a scoping review protocol.

OBJECTIVE: The objective of the review is to examine the literature on patient safety and the teaching and learning strategies required to help students learn about patient safety in undergraduate nursing curricula in prelicensure nursing education programs. INTRODUCTION: Patient safety is a global concern, and health care professionals, including nurses who are on the frontline of health care delivery, should be equipped with the knowledge to enhance patient safety. Undergraduate nursing curricula should include the relevant patient safety content and supply nurse educators with teaching and learning strategies to help students acquire these skills. INCLUSION CRITERIA: Based on the Participants, Concept, and Context (PCC) framework, the eligible population will include nursing students who are enrolled in undergraduate nursing programs and nurse educators who teach in undergraduate nursing programs. The concept of interest is patient safety education, namely, the curricular content and teaching and learning strategies used to help nursing students learn the content. The context is prelicensure nursing education programs at college or university level. Eligible studies will include, but not be limited to, quantitative studies, observational, qualitative, and mixed-methods studies, systematic reviews, and opinion papers. METHODS: Online databases will be searched across MEDLINE, CINAHL, and Web of Science. JBI methodology for scoping reviews will be used to conduct the review. Pre-determined inclusion and exclusion criteria will be used to select relevant studies. Data will be extracted and synthesized from studies that describe patient safety content and teaching and learning strategies in prelicensure nursing education.

Preventing and managing antimicrobial resistance in the African region: A scoping review protocol.

INTRODUCTION: Antimicrobial resistance (AMR) constitutes a significant threat to global health and food security, typically associated with high morbidity and mortality rate. The high burden of infectious diseases coupled with the weak health systems in most countries of Africa magnifies the risk of increasing AMR and its consequences thereof. This scoping review will be aimed at mapping the evidence on interventions used to prevent and manage antimicrobial resistance in Africa, guided by the "One Health" concept. METHODS: We will consider interventions targeting multiple sectors such as health care systems, the agricultural and veterinary sectors. The outcomes to be considered include reduction of AMR decreased morbidity and mortality due to infectious diseases, increased awareness for rational use of antimicrobials and reduced antibiotic consumption. We will include all types of studies regardless of study designs conducted within the context of the WHO African region. Studies will be excluded if they are not conducted in Africa and if they are literature reviews, only describing the concept of AMR without mentioning interventions. We will include studies identified through a comprehensive search of peer-reviewed and grey literature databases. In addition, we will search the reference lists of included studies and relevant reviews. Finally, we plan to do a citation search for included studies. Findings of this review will be narratively synthesized.
