AbstractBackground This study aimed to assess availability of trauma care technology in Ghana. In addition, factors contributing to deficiencies were evaluated. By doing so, potential solutions to inefficient aspects of health systems management and maladapted technology for trauma care in low- and middle-income countries (LMICs) could be identified.Methods Thirty-two items were selected from the World Health Organization’s Guidelines for Essential Trauma Care. Direct inspection and structured interviews with administrative, clinical, and biomedical engineering staff were used to assess the challenges and successes of item availability at 40 purposively sampled district, regional, and tertiary hospitals.ResultsHospital assessments demonstrated marked deficiencies. Some of these were low cost, such as basic airway supplies, chest tubes, and cervical collars. Item non-availability resulted from several contributing factors, namely equipment absence, lack of training, frequent stock-outs, and technology breakage. A number of root causes for these factors were identified, including ineffective healthcare financing by way of untimely national insurance reimbursements, procurement and stock-management practices, and critical gaps in local biomedical engineering and trauma care training. Nonetheless, local examples of successfully overcoming deficiencies were identified (e.g., public–private partnering, ensuring company engineers trained technicians on-the-job during technology installation or servicing).ConclusionWhile availability of several low-cost items could be better supplied by improvements in stock-management and procurement policies, there is a critical need for redress of the national insurance reimbursement system and trauma care training of district hospital staff. Further, developing local service and technical support capabilities is more and more pressing as technology plays an increasingly important role in LMIC healthcare systems.

BACKGROUND This study aimed to assess the availability of pediatric trauma care items (i.e. equipment, supplies, technology) and factors contributing to deficiencies in Ghana. METHODS Ten universal and 9 pediatric-sized items were selected from the World Health Organizations Guidelines for Essential Trauma Care. Direct inspection and structured interviews with administrative, clinical and biomedical engineering staff were used to assess item availability at 40 purposively sampled district, regional and tertiary hospitals in Ghana. RESULTS Hospital assessments demonstrated marked deficiencies for a number of essential items (e.g. basic airway supplies, chest tubes, blood pressure cuffs, electrolyte determination, portable X-ray). Lack of pediatric-sized items resulting from equipment absence, lack of training, frequent stock-outs and technology breakage were common. Pediatric items were consistently less available than adult-sized items at each hospital level. CONCLUSION This study identified several successes and problems with pediatric trauma care item availability in Ghana. Item availability could be improved, both affordably and reliably, by better organization and planning (e.g. regular assessment of demand and inventory, reliable financing for essential trauma care items). In addition, technology items were often broken. Developing local service and biomedical engineering capability was highlighted as a priority to avoid long periods of equipment breakage.

INTRODUCTION Prospective clinical audit of trauma care improves outcomes for the injured in high-income countries (HICs). However, equivalent, context-appropriate audit filters for use in low- and middle-income country (LMIC) district-level hospitals have not been well established. We aimed to develop context-appropriate trauma care audit filters for district-level hospitals in Ghana, was well as other LMICs more broadly. METHODS Consensus on trauma care audit filters was built between twenty panellists using a Delphi technique with four anonymous, iterative surveys designed to elicit: (i) trauma care processes to be measured; (ii) important features of audit filters for the district-level hospital setting; and (iii) potentially useful filters. Filters were ranked on a scale from 0 to 10 (10 being very useful). Consensus was measured with average percent majority opinion (APMO) cut-off rate. Target consensus was defined a priori as: a median rank of ≥9 for each filter and an APMO cut-off rate of ≥0.8. RESULTS Panellists agreed on trauma care processes to target (e.g. triage, phases of trauma assessment, early referral if needed) and specific features of filters for district-level hospital use (e.g. simplicity, unassuming of resource capacity). APMO cut-off rate increased successively: Round 1--0.58; Round 2--0.66; Round 3--0.76; and Round 4--0.82. After Round 4, target consensus on 22 trauma care and referral-specific filters was reached. Example filters include: triage--vital signs are recorded within 15 min of arrival (must include breathing assessment, heart rate, blood pressure, oxygen saturation if available); circulation--a large bore IV was placed within 15 min of patient arrival; referral--if referral is activated, the referring clinician and receiving facility communicate by phone or radio prior to transfer. CONCLUSION This study proposes trauma care audit filters appropriate for LMIC district-level hospitals. Given the successes of similar filters in HICs and obstetric care filters in LMICs, the collection and reporting of prospective trauma care audit filters may be an important step towards improving care for the injured at district-level hospitals in LMICs.

Road Traffic and Other Unintentional Injuries Among Travelers to Developing Countries

Barclay T. Stewart; Isaac Dkofi Yankson; Francis K. Afukaar; Martha Cecilia Hijar Medina; Pham Viet Cuong; Charles Mock

Injuries result in nearly 6 million deaths and incur 52 million disability-adjusted life-years annually, making up 15% of the global disease burden. More than 90% of this burden occurs in low- and middle-income countries. Given this burden, it is not unexpected that injuries are the leading cause of death among travelers to low- and middle-income countries, namely, from road traffic crashes and drowning. Therefore, pretravel advice regarding foreseeable dangers and how to avoid them may significantly mitigate injury risk, such as wearing seatbelts, helmets, and personal flotation devices when appropriate; responsibly consuming alcohol; and closely supervising children.

INTRODUCTION Although two billion people now have access to clean water, many hospitals in low- and middle-income countries (LMICs) do not. Lack of water availability at hospitals hinders safe surgical care. We aimed to review the surgical capacity literature and document the availability of water at health facilities and develop a predictive model of water availability at health facilities globally to inform targeted capacity improvements. METHODS Using Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines, a systematic search for surgical capacity assessments in LMICs in MEDLINE, PubMed, and World Health Organization Global Health Library was performed. Data regarding water availability were extracted. Data from these assessments and national indicator data from the World Bank (e.g., gross domestic product, total health expenditure, and percent of population with improved access to water) were used to create a predictive model for water availability in LMICs globally. RESULTS Of the 72 records identified, 19 reported water availability representing 430 hospitals. A total of 66% of hospitals assessed had water availability (283 of 430 hospitals). Using these data, estimated percent of water availability in LMICs more broadly ranged from under 20% (Liberia) to over 90% (Bangladesh, Ghana). CONCLUSIONS Less than two-thirds of hospitals providing surgical care in 19 LMICs had a reliable water source. Governments and nongovernmental organizations should increase efforts to improve water infrastructure at hospitals, which might aid in the provision of safe essential surgical care. Future research is needed to measure the effect of water availability on surgical care and patient outcomes.

IMPORTANCE Trauma care capacity assessments in developing countries have generated evidence to support advocacy, detailed baseline capabilities, and informed targeted interventions. However, serial assessments to determine the effect of capacity improvements or changes over time have rarely been performed. OBJECTIVE To compare the availability of trauma care resources in Ghana between 2004 and 2014 to assess the effects of a decade of change in the trauma care landscape and derive recommendations for improvements. DESIGN, SETTING, AND PARTICIPANTS Capacity assessments were performed using direct inspection and structured interviews derived from the World Health Organizations Guidelines for Essential Trauma Care. In Ghana, 10 hospitals in 2004 and 32 hospitals in 2014 were purposively sampled to represent those most likely to care for injuries. Clinical staff, administrators, logistic/procurement officers, and technicians/biomedical engineers who interacted, directly or indirectly, with trauma care resources were interviewed at each hospital. MAIN OUTCOMES AND MEASURES Availability of items for trauma care was rated from 0 (complete absence) to 3 (fully available). Factors contributing to deficiency in 2014 were determined for items rated lower than 3. Each item rated lower than 3 at a specific hospital was defined as a hospital-item deficiency. Scores for total number of hospital-item deficiencies were derived for each contributing factor. RESULTS There were significant improvements in mean ratings for trauma care resources: district-level (smaller) hospitals had a mean rating of 0.8 for all items in 2004 vs 1.3 in 2014 (P = .002); regional (larger) hospitals had a mean rating of 1.1 in 2004 vs 1.4 in 2014 (P = .01). However, a number of critical deficiencies remain (eg, chest tubes, diagnostics, and orthopedic and neurosurgical care; mean ratings ≤ 2). Leading contributing factors were item absence (503 hospital-item deficiencies), lack of training (335 hospital-item deficiencies), and stockout of consumables (137 hospital-item deficiencies). CONCLUSIONS AND RELEVANCE There has been significant improvement in trauma care capacity during the past decade in Ghana; however, critical deficiencies remain and require urgent redress to avert preventable death and disability. Serial capacity assessment is a valuable tool for monitoring efforts to strengthen trauma care systems, identifying what has been successful, and highlighting needs.

BACKGROUND Herniorrhaphy is one of the most frequently performed general surgical operations worldwide. However, most low- and middle-income countries (LMICs) are unable to provide this essential surgery to the general public, resulting in considerable morbidity and mortality. This study aimed to estimate the prevalence, barriers to care and disability of untreated hernias in Nepal. METHODS Nepal is a low-income country in South Asia with rugged terrain, infrastructure deficiencies and a severely under-resourced healthcare system resulting in substantial unmet surgical need. A cluster randomized, cross-sectional household survey was performed using the validated Surgeons OverSeas Assessment of Surgical (SOSAS) tool. Fifteen randomized clusters consisting of 30 households with two randomly selected respondents each were sampled to estimate surgical need. The prevalence of and disability from groin hernias and barriers to herniorrhaphy were assessed. RESULTS The survey sampled 1350 households, totaling 2695 individuals (97% response rate). There were 1434 males (53%) with 1.5% having a mass or swelling in the groin at time of survey (95% CI 1.8-4.0). The age-standardized rate for inguinal hernias in men ranged from 1144 per 100,000 persons between age 5 and 49 years and 2941 per 100,000 persons age≥50 years. Extrapolating nationally, there are nearly 310,000 individuals with groin masses and 66,000 males with soft/reducible groin masses in need of evaluation in Nepal. Twenty-nine respondents were not able to have surgery due to lack of surgical services (31%), fear or mistrust of the surgical system (31%) and inability to afford care (21%). Twenty percent were unable to work as previous or perform self-care due to their hernia. CONCLUSIONS Despite the lower than expected prevalence of inguinal hernias, hundreds of thousands of people in Nepal are currently in need of surgical evaluation. Given that essential surgery is a necessary component in health systems, the prevalence of inguinal hernias and the cost-effectiveness of herniorrhaphy, this disease is an important target for LMICs planning surgical capacity improvements.

Abstract Background: Conditions requiring emergency treatment disproportionately affect low- and middle-income countries (LMICs), where there is often insufficient prehospital care capacity. To inform targeted prehospital care development in Ghana, we aimed to describe spatial access to formal prehospital care services and identify ambulance stations for capacity expansion. Methods: Cost distance methods were used to evaluate areal and population-level access to prehospital care within 30 and 60 minutes of each of the 128 ambulance stations in Ghana. With network analysis methods, a two-step floating catchment area model was created to identify district-level variability in access. Districts without NAS stations within their catchment areas were identified as candidates for an additional NAS station. Additionally, five candidate stations for capacity expansion (e.g., addition of an ambulance) were then identified through iterative simulations that were designed to identify the stations that had the greatest influence on the access scores of the ten lowest access districts. Results: Following NAS inception, the proportion of Ghanas landmass serviceable within 60 minutes of a station increased from 8.7 to 59.4% from 2004 to 2014, respectively. Over the same time period, the proportion of the population with access to the NAS within 60-minutes increased from 48% to 79%. The two-step floating catchment area model identified considerable variation in district-level access scores, which ranged from 0.05 to 2.43 ambulances per 100,000 persons (median 0.45; interquartile range 0.23-0.63). Seven candidate districts for NAS station addition and five candidate NAS stations for capacity expansion were identified. The addition of one ambulance to each of the five candidate stations improved access scores in the ten lowest access districts by a total 0.22 ambulances per 100,000 persons. Conclusions: The NAS in Ghana has expanded its population-level spatial access to the majority of the population; however, access inequality exists in both rural and urban areas that can be improved by increasing station capacity or adding additional stations. Geospatial methods to identify access inequities and inform service expansion might serve as a model for other LMICs attempting to understand and improve formal prehospital care services.

IMPORTANCE Conditions that can be treated by surgery comprise more than 16% of the global disease burden. However, 5 billion people do not have access to essential surgical care. An estimated 90% of the 87 million disability-adjusted life-years incurred by surgical conditions could be averted by providing access to timely and safe surgery in low-income and middle-income countries. Population-level spatial access to essential surgery in Ghana is not known. OBJECTIVES To assess the performance of bellwether procedures (ie, open fracture repair, emergency laparotomy, and cesarean section) as a proxy for performing essential surgery more broadly, to map population-level spatial access to essential surgery, and to identify first-level referral hospitals that would most improve access to essential surgery if strengthened in Ghana. DESIGN, SETTING, AND PARTICIPANTS Population-based study among all households and public and private not-for-profit hospitals in Ghana. Households were represented by georeferenced census data. First-level and second-level referral hospitals managed by the Ministry of Health and all tertiary hospitals were included. Surgical data were collected from January 1 to December 31, 2014. MAIN OUTCOMES AND MEASURES All procedures performed at first-level referral hospitals in Ghana in 2014 were used to sort each facility into 1 of the following 3 hospital groups: those without capability to perform all 3 bellwether procedures, those that performed 1 to 11 of each procedure, and those that performed at least 12 of each procedure. Candidates for targeted capability improvement were identified by cost-distance and network analysis. RESULTS Of 155 first-level referral hospitals managed by the Ghana Health Service and the Christian Health Association of Ghana, 123 (79.4%) reported surgical data. Ninety-five (77.2%) did not have the capability in 2014 to perform all 3 bellwether procedures, 24 (19.5%) performed 1 to 11 of each bellwether procedure, and 4 (3.3%) performed at least 12. The essential surgical procedure rate was greater in bellwether procedure-capable first-level referral hospitals than in noncapable hospitals (median, 638; interquartile range, 440-1418 vs 360; interquartile range, 0-896 procedures per 100 000 population; P = .03). Population-level spatial access within 2 hours to a hospital that performed 1 to 11 and at least 12 of each bellwether procedure was 83.2% (uncertainty interval [UI], 82.2%-83.4%) and 71.4% (UI, 64.4%-75.0%), respectively. Five hospitals were identified for targeted capability improvement. CONCLUSIONS AND RELEVANCE Almost 30% of Ghanaians cannot access essential surgery within 2 hours. Bellwether capability is a useful metric for essential surgery more broadly. Similar strategic planning exercises might be useful for other low-income and middle-income countries aiming to improve access to essential surgery.
