A geospatial analysis of two-hour surgical access to district hospitals in South Africa

Geospatial mapping of 2-hour access to timely essential surgery in the Philippines

OBJECTIVES

Timely access to safe and affordable surgery is essential for universal health coverage. To date, there are no studies evaluating 2-hour access to Bellwether procedures (caesarean section, laparotomy, open fracture management) in the Philippines. The objectives of this study were to measure the proportion of the population able to reach a Bellwether hospital within 2 hours in the Philippines and to identify areas in the country with the most surgically underserved populations.

METHODS

All public hospitals with Bellwether capacities were identified from the Philippines Ministry of Health website. The service area tool in ArcGIS Pro was used to determine the population within a 2-hour drive time of a Bellwether facility. Finally, suitability modelling was conducted to identify potential future sites for a surgical facility that targets the most underserved regions in the Philippines.

RESULTS

428 Bellwether capable hospitals were identified. 85.1% of the population lived within 2 hours of one of these facilities. However, 6 regions had less than 80% of its population living within 2 hours of a Bellwether capable facility: Bicol, Eastern Visayas, Zamboanga, Autonomous region of Muslim Mindanao, Caraga and Mimaropa. Suitability analysis identified four regions-Caraga, Mimaropa, Calabarzon and Zamboanga-as ideal locations to build a new hospital with surgical capacity to improve access rates.

CONCLUSION

85.1% of the population of the Philippines are able to reach Bellwether capable hospitals within 2 hours, with regional disparities in terms of access rates. However, other factors such as weather, traffic conditions, financial access, availability of 24-hour surgical services and access to motorised vehicles should also be taken into consideration, as they also affect actual access rates.

Disparities in Access to Trauma Care in Sub-Saharan Africa: a Narrative Review

Purpose of Review

Sub-Saharan Africa is a diverse context with a large burden of injury and trauma-related deaths. Relative to high-income contexts, most of the region is less mature in prehospital and facility-based trauma care, education and training, and trauma care quality assurance. The 2030 Agenda for Sustainable Development recognizes rising inequalities, both within and between countries as a deterrent to growth and development. While disparities in access to trauma care between the region and HICs are more commonly described, internal disparities are equally concerning. We performed a narrative review of internal disparities in trauma care access using a previously described conceptual model.

Recent Findings

A broad PubMed and EMBASE search from 2010 to 2021 restricted to 48 sub-Saharan African countries was performed. Records focused on disparities in access to trauma care were identified and mapped to de Jager’s four component framework. Search findings, input from contextual experts, comparisons based on other related research, and disaggregation of data helped inform the narrative. Only 21 studies were identified by formal search, with most focused on urban versus rural disparities in geographical access to trauma care. An additional 6 records were identified through citation searches and experts. Disparity in access to trauma care providers, detection of indications for trauma surgery, progression to trauma surgery, and quality care provision were thematically analyzed. No specific data on disparities in access to injury care for all four domains was available for more than half of the countries. From available data, socioeconomic status, geographical location, insurance, gender, and age were recognized disparity domains. South Africa has the most mature trauma systems. Across the region, high quality trauma care access is skewed towards the urban, insured, higher socioeconomic class adult. District hospitals are more poorly equipped and manned, and dedicated trauma centers, blood banks, and intensive care facilities are largely located within cities and in southern Africa. The largest geographical gaps in trauma care are presumably in central Africa, francophone West Africa, and conflict regions of East Africa. Disparities in trauma training opportunities, public–private disparities in provider availability, injury care provider migration, and several other factors contribute to this inequity. National trauma registries will play a role in internal inequity monitoring, and deliberate development implementation of National Surgical, Obstetrics, and Anesthesia plans will help address disparities. Human, systemic, and historical factors supporting these disparities including implicit and explicit bias must be clearly identified and addressed. Systems approaches, strategic trauma policy frameworks, and global and regional coalitions, as modelled by the Global Alliance for Care of the Injured and the Bellagio group, are key. Inequity in access can be reduced by prehospital initiatives, as used in Ghana, and community-based insurance, as modelled by Rwanda.

Summary

Sub-Saharan African countries have underdeveloped trauma systems. Consistent in the narrative is the rural-urban disparity in trauma care access and the disadvantage of the poor. Further research is needed in view of data disparity. Recognition of these disparities should drive creative equitable solutions and focused interventions, partnerships, accompaniment, and action.

Use of geospatial analysis for priority setting in surgical system investment in Guatemala

Background

Two-hour and 30 min travel times to a hospital capable of performing emergency general surgery and cesarean section are benchmarks for timely surgical access. This study aimed to estimate the population of Guatemala with timely access to surgical care and identify existing hospitals where the expansion of surgical services would increase access.

Methods

The World Federation of Societies of Anaesthesiologists (WFSA) Anesthesia Facility Assessment Tool (AFAT) previously identified 37 public Guatemalan hospitals that provide surgical care. Nine additional public non-surgical hospitals were also identified. Geospatial analysis was performed to estimate walking and driving geographic access to all 46 hospitals. We calculated the potential increase in access that would accompany the expansion of surgical services at each of the nine non-surgical hospitals.

Findings

The percentage of the population with walking access to a surgical hospital within 30 min, 1 h, and 2 h are 5·1%, 12·9%, and 27·3%, respectively. The percentage of people within 30 min, 1 h, and 2 h driving times are 27·3%, 41·1%, and 53·1%, respectively. The median percentage of the population within each of Guatemala's 22 administrative departments with 2 h walking access was 19·0% [IQR 14·1-30·7] and 2 h driving access was 52·4% [IQR 30·5-62·8]. Expansion of surgical care at existing public Guatemalan hospitals in Guatemala would result in a minimal increase in overall geographic access compared to current availability.

Interpretation

While Guatemala provides universal health coverage, geographic access to surgical care remains inadequate. Geospatial mapping and survey data work synergistically to assess surgical system strength and identify gaps in geographic access to essential surgical care.

Funding

None.

Estimating the Specialist Surgical Workforce Density in South Africa

Background

South Africa is an upper middle-income country with inequitable access to healthcare. There is a maldistribution of doctors between the private and public sectors, the latter which serves 86% of the population but has less than half of the human resources.

Objective

The objective of this study was to estimate the specialist surgical workforce density in South Africa.

Methods

This was a retrospective record-based review of the specialist surgical workforce in South Africa as defined by registration with the Health Professionals Council of South Africa for three cadres: 1) surgeons, and 2) anaesthesiologists, and 3) obstetrician/gynaecologists (OBGYN).

Findings

The specialist surgical workforce in South Africa doubled from 2004 (N = 2956) to 2019 (N = 6144). As of December 2019, there were 3096 surgeons (50.4%), 1268 (20.6%) OBGYN, and 1780 (29.0%) anaesthesiologists. The specialist surgical workforce density in 2019 was 10.5 per 100,000 population which ranged from 1.8 in Limpopo and 22.8 per 100,000 in Western Cape province. The proportion of females and those classified other than white increased between 2004-2019.

Conclusion

South Africa falls short of the minimum specialist workforce density of 20 per 100,000 to provide adequate essential and emergency surgical care. In order to address the current and future burden of disease treatable by surgical care, South Africa needs a robust surgical healthcare system with adequate human resources, to translate healthcare services into improved health outcomes.
