Modeling the Scale-up of Surgical Services for Children with Surgically Treatable Congenital Conditions in Somaliland.

BACKGROUND: Congenital conditions comprise a significant portion of the global burden of surgical conditions in children. In Somaliland, over 250,000 children do not receive required surgical care annually, although the estimated costs and benefits of scale-up of children's surgical services to address this disease burden is not known. METHODS: We developed a Markov model using a decision tree template to project the costs and benefits of scale-up of surgical care for children across Somaliland. We used a proxy set of congenital anomalies across Somaliland to estimate scale-up costs using three different scale-up rates. The cost-effectiveness ratio and net societal monetary benefit were estimated using these models, supported by disability weights in existing literature. RESULTS: Overall, we found that scale-up of surgical services at an aggressive rate (22.5%) over a 10-year time horizon is cost effective. Although the scale-up of surgical care for most conditions in the proxy set was cost effective, scale-up of hydrocephalus and spina bifida are not as cost effective as other conditions. CONCLUSIONS: Our analysis concludes that it is cost effective to scale-up surgical services for congenital anomalies for children in Somaliland.

Barriers to Surgical Care Among Children in Somaliland: An Application of the Three Delays Framework.

BACKGROUND: There are complex barriers that increase delays to surgical care in low- and middle-income countries, particularly among the vulnerable population of children. Understanding these barriers to surgical care can result in targeted and strategic intervention efforts to improve care for children. The three-delay model is a widely used framework in global health for evaluating barriers associated with seeking (D1), reaching (D2), and receiving health care (D3). The goal of our study is to evaluate reasons for delays in the surgical care for children in Somaliland using the three-delay framework. METHODS: Data were collected in a cross-sectional study in Somaliland from 1503 children through a household survey. Among children with a surgical need, we quantified the number of children seeking, reaching, and receiving care along the surgical care continuum, according to the three-delay framework. We evaluated predictors of the three delays through a multivariate logistic regression model, including the child's age, gender, village type, household income level, region, and household size. RESULTS: Of the 196 children identified with a surgical condition, 50 (27.3%) children had a delay in seeking care (D1), 28 (20.6%) children had a delay in reaching care (D2), and 84 (71.2%) children had a delay in receiving care (D3), including 10 children who also experienced D1 and D2. The main reasons cited for D1 included seeking a traditional healthcare provider, while lack of money and availability of care were main reasons cited for D2. Significant predictors for delays included household size for D1 and D3 and condition type and region for D2. CONCLUSION: Children in Somaliland experience several barriers to surgical care along the entire continuum of care, allowing for policy guidance tailored to specific local challenges and resources. Since delays in surgical care for children can substantially impact the effectiveness of surgical interventions, viewing delays in surgical care under the lens of the three-delay framework can inform strategic interventions along the pediatric surgical care continuum, thereby reducing delays and improving the quality of surgical care for children.

Waiting Too Long: The Contribution of Delayed Surgical Access to Pediatric Disease Burden in Somaliland.

BACKGROUND: Delayed access to surgical care for congenital conditions in low- and middle-income countries is associated with increased risk of death and life-long disabilities, although the actual burden of delayed access to care is unknown. Our goal was to quantify the burden of disease related to delays to surgical care for children with congenital surgical conditions in Somaliland. METHODS: We collected data from medical records on all children (n = 280) receiving surgery for a proxy set of congenital conditions over a 12-month time period across all 15 surgically equipped hospitals in Somaliland. We defined delay to surgical care for each condition as the difference between the ideal and the actual ages at the time of surgery. Disability-adjusted life years (DALYs) attributable to these delays were calculated and compared by the type of condition, travel distance to care, and demographic characteristics. RESULTS: We found long delays in surgical care for these 280 children with congenital conditions, translating to a total of 2970 attributable delayed DALYs, or 8.4 avertable delayed DALYs per child, with the greatest burden among children with neurosurgical and anorectal conditions. Over half of the families seeking surgical care had to travel over 2 h to a surgically equipped hospital in the capital city of Hargeisa. CONCLUSIONS: Children with congenital conditions in Somaliland experience substantial delays to surgical care and travel long distances to obtain care. Estimating the burden of delayed surgical care with avertable delayed DALYs offers a powerful tool for estimating the costs and benefits of interventions to improve the quality of surgical care.

Provision of Surgical Care for Children Across Somaliland: Challenges and Policy Guidance.

BACKGROUND: Existing data suggest a large burden of surgical conditions in low- and middle-income countries (LMICs). However, surgical care for children in LMICs remains poorly understood. Our goal was to define the hospital infrastructure, workforce, and delivery of surgical care for children across Somaliland and provide policy guidance to improve care. METHODS: We used two established hospital assessment tools to assess infrastructure, workforce, and capacity at all hospitals providing surgical care for children across Somaliland. We collected data on all surgical procedures performed in children in Somaliland between August 2016 and July 2017 using operative logbooks. RESULTS: Data were collected from 15 hospitals, including eight government, five for-profit, and two not-for-profit hospitals. Children represented 15.9% of all admitted patients, and pediatric surgical interventions comprised 8.8% of total operations. There were 0.6 surgical providers and 1.2 anesthesia providers per 100,000 population. A total of 1255 surgical procedures were performed in children in all hospitals in Somaliland over 1 year, at a rate of 62.4 surgical procedures annually per 100,000 children. Care was concentrated at private hospitals within urban areas, with a limited number of procedures for many high-burden pediatric surgical conditions. CONCLUSIONS: We found a profound lack of surgical capacity for children in Somaliland. Hospital-level surgical infrastructure, workforce, and care delivery reflects a severely resource-constrained health system. Targeted policy to improved essential surgical care at local, regional, and national levels is essential to improve the health of children in Somaliland.

Non-physician anaesthesia providers' perspectives on task sharing practices in Zambia and Somaliland: a qualitative study.

INTRODUCTION: The 68th World Health Assembly, in 2015, called for surgical and anaesthesia services strengthening. Acknowledging the healthcare staff shortages, they referred to task sharing, among others, as a more effective use of the healthcare workforce. While task sharing has been increasingly proposed as an important strategy to increase the reach and safety of anaesthesia as well as a means of supporting the workforce in low-resource settings, most data on task sharing relate to non-anaesthetic healthcare contexts. The aim of this study was to understand anaesthetic task sharing as currently experienced and/or envisaged by non-physician anaesthesia providers in Zambia and Somaliland. METHODS: An exploratory qualitative research methodology was used. Participants were recruited initially via contacts of the research team, then through snowballing using a purposive sampling strategy. There were 13 participants: 7 from Somaliland and 6 from Zambia. Semistructured interviews took place synchronously, then were recorded, anonymised, transcribed and analysed thematically. Triangulation and respondents' validation were used to maximise data validity. RESULTS: Four major themes were identified in relation to task sharing practices: (1) participants recognised variable components of task sharing in their practice; (2) access to task sharing depends both on sources and resources; (3) implicit barriers may inhibit task sharing practices; (4) there is an appetite among participants for amelioration of current task sharing practices. CONCLUSIONS: Empowering task sharing practices can be achieved only by understanding how these practices work, by identifying gaps and areas of improvement, and by addressing them. The findings from this exploratory study could help the global community understand how anaesthetic task sharing in low-resource settings works and inspire further research on the field. This could inform future modelling of workforce planning strategies in low-resource settings to maximise the effectiveness and professional well-being of the workforce.

Assessment of anesthesia capacity for children in Somaliland.

The burden of pediatric surgical conditions in Somaliland is high and the pediatric anesthesia capacity across the country remains poorly understood. The international standards developed by the World Health Organization and World Federation of Societies of Anaesthesiologists (WHO-WFSA) serve as a guideline to assess the provision of anesthetic care. This study aims to describe anesthesia capacity for children in Somaliland and assess progress towards reaching the WHO-WFSA international standards. In this cross-sectional study, anesthesia infrastructure and workforce data, as well as pediatric clinical and demographic data were collected from fifteen private, charity, and government hospitals in the six regions of Somaliland. We described anesthesia capacity in Somaliland and compared baseline data to the WHO-WFSA international standards. Overall, Somaliland did not reach most of the target goals for anesthesia capacity as defined by the WHO-WFSA. Most markers for anesthesia capacity were far behind the established targets, with deficits of 99% for anesthesiologists density, 83% for operating room density, and 83% for ventilator density. Hospitals in urban Maroodi-Jeex, and private hospitals had more supplies, infrastructure, and surgical personnel than hospitals in rural areas. There are large gaps in current anesthetic resources for children according to WHO-WFSA global standards, as well as wide disparities between regions and types of hospitals in Somaliland. Increased investment in anesthesia infrastructure and workforce is required to meet the needs of pediatric surgical patients across the country.

Delays in care for hydrocephalus and spina bifida at a tertiary hospital in Somaliland.

Background: Childhood neurosurgical conditions such as hydrocephalus and spina bifida represent a significant burden of death and disability worldwide, particularly in low and middle-income countries. However, there are limited data on the disease prevalence and delays in care for pediatric neurosurgical conditions in very low-resource settings. This study aims to characterize the delays in access to care for pediatric neurosurgical conditions in Somaliland. Methods: We performed a retrospective review of all children with congenital hydrocephalus and spina bifida admitted to the Edna University Hospital (EAUH) in Somaliland between 2011 and 2018. Patient demographics were analyzed with descriptive statistics and χ2 test statistics. We defined delays in care for each condition based on standard care in high-income settings. Univariate and multivariate logistic regression were performed to evaluate predictors of delay in care. Statistical significance was set at p<0.05. Results: A total of 344 children were admitted to EAUH with neurosurgical conditions from 2011 to 2018. The most common condition was congenital hydrocephalus (62%). Delays in care were found for 90% of patients and were associated with the type of diagnosis and region. The longest delay among children with spina bifida was 60 months, while the longest delay for children with congenital hydrocephalus was 36 months. Children with congenital hydrocephalus or spina bifida traveling from foreign countries had the highest waiting time to receive care, with a median delay of 8 months (IQR: 5-11 months) and 4 months (IQR: 3-7 months), respectively. Conclusion: We found significant delays in care for children with neurosurgical conditions in Somaliland. This country has an urgent need to scale up its surgical infrastructure, workforce, and referral pathways to address the needs of children with hydrocephalus and spina bifida.

Does reducing out-of-pocket costs for children's surgical care protect families from poverty in Somaliland? A cross-sectional, national, economic evaluation modelling study.

OBJECTIVES: An estimated 1.7 billion children around the world do not have access to safe, affordable and timely surgical care, with the financing through out-of-pocket (OOP) expenses being one of the main barriers to care. Our study modelled the impact of reducing OOP costs related to surgical care for children in Somaliland on the risk of catastrophic expenditures and impoverishment. DESIGN AND SETTING: This cross-sectional nationwide economic evaluation modelled several different approaches to reduction of paediatric OOP surgical costs in Somaliland. PARTICIPANTS AND OUTCOME MEASURES: A surgical record review of all procedures on children up to 15 years old was conducted at 15 surgically capable hospitals. We modelled two rates of OOP cost reduction (reduction of OOP proportion from 70% to 50% and from 70% to 30% reduction in OOP costs) across five wealth quintiles (poorest, poor, neutral, rich, richest) and two geographical areas (urban and rural). The outcome measures of the study are catastrophic expenditures and risk of impoverishment due to surgery. We followed the Consolidated Health Economic Evaluation Reporting Standards. RESULTS: We found that the risk of catastrophic and impoverishing expenditures related to OOP expenditures for paediatric surgery is high across Somaliland, but most notable in the rural areas and among the poorest quintiles. Reducing OOP expenses for surgical care to 30% would protect families in the richest wealth quintiles while minimally affecting the risk of catastrophic expenditure and impoverishment for those in the lowest wealth quintiles, particularly those in rural areas. CONCLUSION: Our models suggest that the poorest communities in Somaliland lack protection against the risk of catastrophic health expenditure and impoverishment, even if OOP payments are reduced to 30% of surgical costs. A comprehensive financial protection in addition to reduction of OOP costs is required to prevent risk of impoverishment in these communities.

Determinants of COVID-19 Vaccine Uptake and Acceptability in the Horn of Africa: Evidence from Somaliland.

Various COVID-19 vaccines have been developed in an unprecedented time and were rolled out across the world to save lives during the COVID-19 pandemic. Yet statistics show that COVID-19 uptake and acceptance in the Horn of Africa have been very low. To examine factors associated with COVID-19 vaccine uptake and acceptance in Somaliland, we carried out a cross-sectional study using a structured questionnaire both in offline and online modes. The study population was adults from the age of 18 years and above. Of the 704 respondents who participated in the survey, only 37% took the vaccine. Surprisingly, about 65% of those who have not taken the vaccine were unwilling to get vaccinated. Using a binomial logistic regression, we find that older people, the more educated and those who are employed are more likely to take the vaccine. Our results also show that the perceived threat of the virus and the perceived safety of the vaccine significantly increase vaccine uptake and acceptance. Results of this study will help the government and other concerned parties shape policies that can boost vaccine uptake and acceptance.

Bond Relationship of Carbon Fiber-Reinforced Polymer (CFRP) Strengthened Steel Plates Exposed to Service Temperature.

Emerging as a new technology, carbon fiber-reinforced polymer (CFRP) has been introduced to rehabilitate and strengthen steel structures using an adhesive agent. However, the outdoor service temperature is potentially degrading to the mechanical strength of the adhesive, as well as affecting the bonding of the strengthened steel structure. Therefore, this paper aims to investigate the bond relationship of CFRP-strengthened steel plates exposed to service temperatures. Two types of experiments were conducted to determine the tensile and flexural performance of CFRP-strengthened steel plates. The experiments were designed using a Box-Behnken design (BBD) and response surface methodology (RSM) by considering three parameters: service temperature (25 °C, 45 °C and 70 °C), number of CFRP layers (one, three and five layers) and bond length (40, 80 and 120 mm). The findings show the dominant failure mode transformed from adhesion failure between steel and adhesive interfaces to adhesion failure between CFRP and adhesive interfaces as the service temperature increased. The tensile strength improved by 25.62% when the service temperature increased. Field emission scanning electron microscope (FESEM) analysis proved that the strength enhancement is due to the densification and reduction of the adhesive particle microstructure gaps through the softening effect at service temperature. However, service temperature is found to have less impact on flexural strength. Incorporating the experimental results in RSM, two quadratic equations were developed to estimate the tensile and flexural strength of CFRP-strengthened steel plates. The high coefficient of determination, R2, yields at 0.9936 and 0.9846 indicate the high reliability of the models. Hence, it can be used as an estimation tool in the design stage.

Geospatial analysis of pediatric surgical need and geographical access to care in Somaliland: a cross-sectional study.

BACKGROUND: The global burden of disease in children is large and disproportionally affects low-income and middle-income countries (LMICs). Geospatial analysis offers powerful tools to quantify and visualise disparities in surgical care in LMICs. Our study aims to analyse the geographical distribution of paediatric surgical conditions and to evaluate the geographical access to surgical care in Somaliland. METHODS: Using the Surgeons OverSeas Assessment of Surgical Need survey and a combined survey from the WHO's (WHO) Surgical Assessment Tool-Hospital Walkthrough and the Global Initiative for Children's Surgery Global Assessment in Paediatric Surgery, we collected data on surgical burden and access from 1503 children and 15 hospitals across Somaliland. We used several geospatial tools, including hotspot analysis, service area analysis, Voronoi diagrams, and Inverse Distance Weighted interpolation to estimate the geographical distribution of paediatric surgical conditions and access to care across Somaliland. RESULTS: Our analysis suggests less than 10% of children have timely access to care across Somaliland. Patients could travel up to 12 hours by public transportation and more than 2 days by foot to reach surgical care. There are wide geographical disparities in the prevalence of paediatric surgical conditions and access to surgical care across regions. Disparities are greater among children travelling by foot and living in rural areas, where the delay to receive surgery often exceeds 3 years. Overall, Sahil and Sool were the regions that combined the highest need and the poorest surgical care coverage. CONCLUSION: Our study demonstrated wide disparities in the distribution of surgical disease and access to surgical care for children across Somaliland. Geospatial analysis offers powerful tools to identify critical areas and strategically allocate resources and interventions to efficiently scale-up surgical care for children in Somaliland.

Long-Term Strength Development of Fly Ash-Based One-Part Alkali-Activated Binders.

This research aims to study the effect of the dosage of anhydrous sodium metasilicate activator on the long-term properties of fly ash-based one-part alkali-activated binders (OPAAB) cured at ambient conditions. Powdered sodium metasilicate activator was utilized in the range of 8-16% by weight of the fly ash in producing the OPAAB. The properties examined are hardened density, compressive strength, flexural strength, water absorption, efflorescence formation, and microstructural analysis. The experimental result revealed that the binders exhibited excellent long-term strength properties. The compressive strength of the OPAAP is well correlated with its hardened density. The pastes were found to exhibit good soundness characteristics over the long-term. The absorption of water decreases with an increase in the activator dosage from 8-12%, and beyond that, the water absorption relatively remains the same. Field emission scanning electron microscope (FESEM) micrograph revealed uniformly formed solid matrices with the micro-crack present were observed in the samples. The larger pore size promotes the crystallization of the resulting hydrate substances (N, C)-A-S-H gel. The initial dissolution of the OPAAP occurred within the first 30 min. At longer age of curing, mixtures with a higher dosage of powdered activator tend to absorb less water. Strength properties beyond 28 days are considered as the long-term strength.

Interpreting the Lancet surgical indicators in Somaliland: a cross-sectional study.

BACKGROUND: The unmet burden of surgical care is high in low-income and middle-income countries. The Lancet Commission on Global Surgery (LCoGS) proposed six indicators to guide the development of national plans for improving and monitoring access to essential surgical care. This study aimed to characterise the Somaliland surgical health system according to the LCoGS indicators and provide recommendations for next-step interventions. METHODS: In this cross-sectional nationwide study, the WHO's Surgical Assessment Tool-Hospital Walkthrough and geographical mapping were used for data collection at 15 surgically capable hospitals. LCoGS indicators for preparedness was defined as access to timely surgery and specialist surgical workforce density (surgeons, anaesthesiologists and obstetricians/SAO), delivery was defined as surgical volume, and impact was defined as protection against impoverishment and catastrophic expenditure. Indicators were compared with the LCoGS goals and were stratified by region. RESULTS: The healthcare system in Somaliland does not meet any of the six LCoGS targets for preparedness, delivery or impact. We estimate that only 19% of the population has timely access to essential surgery, less than the LCoGS goal of 80% coverage. The number of specialist SAO providers is 0.8 per 100 000, compared with an LCoGS goal of 20 SAO per 100 000. Surgical volume is 368 procedures per 100 000 people, while the LCoGS goal is 5000 procedures per 100 000. Protection against impoverishing expenditures was only 18% and against catastrophic expenditures 1%, both far below the LCoGS goal of 100% protection. CONCLUSION: We found several gaps in the surgical system in Somaliland using the LCoGS indicators and target goals. These metrics provide a broad view of current status and gaps in surgical care, and can be used as benchmarks of progress towards universal health coverage for the provision of safe, affordable, and timely surgical, obstetric and anaesthesia care in Somaliland.

Prevalence of Pediatric Surgical Conditions Across Somaliland.

Importance: Although surgical conditions are increasingly recognized as causing a significant health care burden among adults in low- and middle-income countries (LMICs), the burden of surgical conditions among children in LMICs remains poorly defined. Objective: To estimate the prevalence of pediatric surgical conditions across Somaliland using a nationwide community-based household survey. Design, Setting, and Participants: This cross-sectional study was conducted through a national community-based sampling survey from August through December 2017 in Somaliland. Participants were 1503 children surveyed using the Surgeons OverSeas Assessment of Surgical Need (SOSAS). Main Outcomes and Measures: The SOSAS survey contains 2 components, including a section on household demographics, deaths, and financial information and sections querying children's history of surgical conditions. Results: In this cross-sectional study that included 1503 children (55.6% male; mean [SE] age, 6.4 [0.1] years), 221 surgical conditions were identified among 196 children, yielding a mean (SE) prevalence of pediatric surgical conditions of 12.2% (1.5%). Only 53 of these 221 surgical conditions (23.7%) had been surgically corrected at the time of the survey. The most common conditions encountered were congenital anomalies (33.8%) and wound-related injuries (24.6%). Nationally, an estimated 256 745 children have surgical conditions, with an estimated 88 345 to 199 639 children having unmet surgical needs. Conclusions and Relevance: Using national sampling, this study found that children have a high burden of surgical conditions in Somaliland. These data highlight the need for a scale-up of pediatric surgical infrastructure and resources to provide the needed surgical care for children in LMICs.

The contribution of pediatric surgery to poverty trajectories in Somaliland.

BACKGROUND: The provision of health care in low-income and middle-income countries (LMICs) is recognized as a significant contributor to economic growth and also impacts individual families at a microeconomic level. The primary goal of our study was to examine the relationship between surgical conditions in children and the poverty trajectories of either falling into or coming out of poverty of families across Somaliland. METHODS: This work used the Surgeons OverSeas Assessment of Surgical Need (SOSAS) tool, a validated household, cross-sectional survey designed to determine the burden of surgical conditions within a community. We collected information on household demographic characteristics, including financial information, and surgical condition history on children younger than 16 years of age. To assess poverty trajectories over time, we measured household assets using the Stages of Progress framework. RESULTS: We found there were substantial fluxes in poverty across Somaliland over the study period. We confirmed our study hypothesis and found that the presence of a surgical condition in a child itself, regardless of whether surgical care was provided, either reduced the chances of moving out of poverty or increased the chances of moving towards poverty. CONCLUSION: Our study shows that the presence of a surgical condition in a child is a strong singular predictor of poverty descent rather than upward mobility, suggesting that this stressor can limit the capacity of a family to improve its economic status. Our findings further support many existing macroeconomic and microeconomic analyses that surgical care in LMICs offers financial risk protection against impoverishment.

Evaluation of the Effect of Combined Low Energy Laser Application and Micro-Osteoperforations versus the Effect of Application of Each Technique Separately On the Rate of Orthodontic Tooth Movement.

AIM: The study was conducted to evaluate the effect of combined low energy laser application and Micro-Osteoperforations versus the effect of the application of each technique separately on the rate of orthodontic tooth movement. PATIENTS AND METHODS: Three parallel groups (each group contained 10 patients) were performed; Group A: In which one side was controlled side, and the other side received micro-osteoperforations (MOPs), Group B: In which one side was controlled side, and the other side received low-level laser therapy (LLLT), Group C: In which one side was controlled side, and the other side received both MOPs and LLLT. RESULTS: Significant statistical differences were obvious in the rate of canine retraction between each intervention and the control sides as following; the MOPs increased the rate of canine retraction by 1.6 fold more than the control side, LLLT increased the rate of canine retraction by 1.3 fold than the control side, and combination of both techniques resulted in an increase in the rate of canine retraction by 1.8 fold more than the control side. CONCLUSION: Combination of MOPs and LLLT proved to be more efficient regarding increasing the rate of canine retraction than the application of each technique separately.
