A Nationwide Enumeration of the Surgical Workforce, its Production and Disparities in Operative Productivity in Liberia.

BACKGROUND: Any health care system that strives to deliver good health and well-being to its population relies on a trained workforce. The aim of this study was to enumerate surgical provider density, describe operative productivity and assess the association between key surgical system characteristics and surgical provider productivity in Liberia. METHODS: A nationwide survey of operation theatre logbooks, available human resources and facility infrastructure was conducted in 2018. Surgical providers were counted, and their productivity was calculated based on operative numbers and full-time equivalent positions. RESULTS: A total of 286 surgical providers were counted, of whom 67 were accredited specialists. This translated into a national density of 1.6 specialist providers per 100,000 population. Non-specialist physicians performed 58.3 percent (3607 of 6188) of all operations. Overall, surgical providers performed a median of 1.0 (IQR 0.5-2.7) operation per week, and there were large disparities in operative productivity within the workforce. Most operations (5483 of 6188) were categorized as essential, and each surgical provider performed a median of 2.0 (IQR 1.0-5.0) different types of essential procedures. Surgical providers who performed 7-14 different types of essential procedures were more than eight times as productive as providers who performed 0-1 essential procedure (operative productivity ratio = 8.66, 95% CI 6.27-11.97, P < 0.001). CONCLUSION: The Liberian health care system struggles with an alarming combination of few surgical providers and low provider productivity. Disaggregated data can provide a high-resolution picture of local challenges that can lead to local solutions.

Clean Cut (adaptive, multimodal surgical infection prevention programme) for low-resource settings: a prospective quality improvement study.

BACKGROUND: Clean Cut is an adaptive, multimodal programme to identify improvement opportunities and safety changes in surgery by enhancing outcomes surveillance, closing gaps in surgical infection prevention standards, and strengthening underlying processes of care. Surgical-site infections (SSIs) are common in low-income countries, so this study assessed a simple intervention to improve perioperative infection prevention practices in one. METHODS: Clean Cut was implemented in five hospitals in Ethiopia from August 2016 to October 2018. Compliance data were collected from the operating room focused on six key perioperative infection prevention standards. Process-mapping exercises were employed to understand barriers to compliance and identify locally driven improvement opportunities. Thirty-day outcomes were recorded on patients for whom intraoperative compliance information had been collected. RESULTS: Compliance data were collected from 2213 operations (374 at baseline and 1839 following process improvements) in 2202 patients. Follow-up was completed in 2159 patients (98·0 per cent). At baseline, perioperative teams complied with a mean of only 2·9 of the six critical perioperative infection prevention standards; following process improvement changes, compliance rose to a mean of 4·5 (P < 0·001). The relative risk of surgical infections after Clean Cut implementation was 0·65 (95 per cent c.i. 0·43 to 0·99; P = 0·043). Improved compliance with standards reduced the risk of postoperative infection by 46 per cent (relative risk 0·54, 95 per cent c.i. 0·30 to 0·97, for adherence score 3-6 versus 0-2; P = 0·038). CONCLUSION: The Clean Cut programme improved infection prevention standards to reduce SSI without infrastructure expenses or resource investments.

Variation in global uptake of the Surgical Safety Checklist.

BACKGROUND: The Surgical Safety Checklist (SSC) is a patient safety tool shown to reduce mortality and to improve teamwork and adherence with perioperative safety practices. The results of the original pilot work were published 10 years ago. This study aimed to determine the contemporary prevalence and predictors of SSC use globally. METHODS: Pooled data from the GlobalSurg and Surgical Outcomes studies were analysed to describe SSC use in 2014-2016. The primary exposure was the Human Development Index (HDI) of the reporting country, and the primary outcome was reported SSC use. A generalized estimating equation, clustering by facility, was used to determine differences in SSC use by patient, facility and national characteristics. RESULTS: A total of 85 957 patients from 1464 facilities in 94 countries were included. On average, facilities used the SSC in 75·4 per cent of operations. Compared with very high HDI, SSC use was less in low HDI countries (odds ratio (OR) 0·08, 95 per cent c.i. 0·05 to 0·12). The SSC was used less in urgent compared with elective operations in low HDI countries (OR 0·68, 0·53 to 0·86), but used equally for urgent and elective operations in very high HDI countries (OR 0·96, 0·87 to 1·06). SSC use was lower for obstetrics and gynaecology versus abdominal surgery (OR 0·91, 0·85 to 0·98) and where the common or official language was not one of the WHO official languages (OR 0·30, 0·23 to 0·39). CONCLUSION: Worldwide, SSC use is generally high, but significant variability exists. Implementation and dissemination strategies must be developed to address this variability.

ANTECEDENTES: Se ha demostrado que la utilización de la lista de verificación de seguridad quirúrgica (Surgical Safety Checklist, SSC) reduce la mortalidad y mejora el trabajo en equipo, así como el cumplimiento de las prácticas de seguridad perioperatorias. Los resultados de un trabajo piloto original se publicaron hace 10 años. El objetivo de este estudio fue determinar la prevalencia actual y los predictores de uso de la SSC a nivel mundial. MÉTODOS: Se analizaron los datos agrupados de los estudios GlobalSurg y Surgical Outcomes para describir la utilización de la SSC entre 2014-2016. La principal variable de exposición fue el índice de desarrollo humano (Human Development Index, HDI) del país informante y la principal variable de resultado, la tasa de utilización de la SCC. Para determinar las diferencias en la utilización de la SSC por paciente, centro y características nacionales se utilizó una ecuación de estimación generalizada con conglomerados por centros. RESULTADOS: Se incluyeron 85.957 pacientes de 1.464 centros en 94 países. La tasa media de utilización de la SSC fue del 75,4% de las operaciones. Al compararlos con países de HDI muy alto, la utilización de la SCC fue menor en los países con HDI bajo (razón de oportunidades, odds ratio, OR 0,08, i.c. del 95% 0,05-0,12). En países con HDI bajo, la SSC se utilizó menos en operaciones urgentes en comparación con operaciones electivas (OR 0,68, i.c. del 95% 0,53- 0,86) a diferencia de los países con HDI elevado, en los que se utilizó por igual en ambas situaciones (OR 0,96, i.c. del 95% 0,87-1,06). La utilización de la SSC fue menor en operaciones de obstetricia y ginecología que en cirugía abdominal (OR 0,91, i.c. del 95% 0,85 a 0,98) y en aquellos países en los que el idioma habitual u oficial era diferente a los idiomas oficiales de la OMS (OR 0,30, i.c. del 95% 0,23 a 0,39). CONCLUSIÓN: A nivel mundial, el uso de SSC en general es alto, pero existe una variabilidad significativa. Se deben desarrollar estrategias de implementación y difusión para resolver esta variabilidad.

The Lifebox Surgical Headlight Project: engineering, testing, and field assessment in a resource-constrained setting.

BACKGROUND: Poor surgical lighting represents a major patient safety issue in low-income countries. This study evaluated device performance and undertook field assessment of high-quality headlights in Ethiopia to identify critical attributes that might improve safety and encourage local use. METHODS: Following an open call for submissions (December 2018 to January 2019), medical and technical (non-medical) headlights were identified for controlled specification testing on 14 prespecified parameters related to light quality/intensity, mounting and battery performance, including standardized illuminance measurements over time. The five highest-performing devices (differential illumination, colour rendering, spot size, mounting and battery duration) were distributed to eight Ethiopian surgeons working in resource-constrained facilities. Surgeons evaluated the devices in operating rooms, and in a comparative session rated each headlight in terms of performance and willingness to purchase. RESULTS: Of 25 submissions, eight headlights (6 surgical and 2 technical) met the criteria for full specification testing. Scores ranged from 8 to 12 (of 14), with differential performance in lighting, mounting and battery domains. Only two headlights met the illuminance parameters of more than 35 000 lux during initial testing, and no headlight satisfied all minimum specifications. Of the five headlights evaluated in Ethiopia, daily operation logbooks noted variability in surgeons' opinions of lighting quality (6-92 per cent) and spot size (0-92 per cent). Qualitative interviews also yielded important feedback, including preference for easy transport. Surgeons sought high quality with price sensitivity (using out-of-pocket funds) and identified the least expensive but high-functioning device as their first choice. CONCLUSION: No device satisfied all the predetermined specifications, and large price discrepancies were critical factors leading surgeons' choices. The favoured device is undergoing modification by the manufacturer based on design feedback so an affordable, high-quality surgical headlight crafted specifically for the needs of resource-constrained settings can be used to improve surgical safety.

ANTECEDENTES: Una iluminación quirúrgica deficiente conlleva importantes problemas de seguridad para los pacientes en países de bajos ingresos. En Etiopía, se evaluó el rendimiento y la capacidad de iluminar el campo quirúrgico de varias lámparas de alta calidad para identificar aspectos esenciales que podrían mejorar la seguridad y fomentar su uso local. MÉTODOS: Tras una convocatoria abierta (diciembre de 2018-enero de 2019), se identificaron lamparás médicas y técnicas (no médicas) para realizar un análisis de 14 variables previamente definidas en relación con la calidad/intensidad de la luz, montaje y rendimiento de la batería, además de mediciones estandarizadas de iluminancia a largo plazo. Los cinco dispositivos de mayor rendimiento (iluminación diferencial, reproducción del color, tamaño del foco, montaje y duración de la batería) se distribuyeron entre 8 cirujanos etíopes que trabajaban en instalaciones con recursos limitados. Los cirujanos evaluaron los dispositivos en quirófano y en sesiones comparativas calificaron el rendimiento de cada lámpara y la disposición para su compra. RESULTADOS: De las 25 propuestas presentadas, 8 lámparas (6 quirúrgicas y 2 técnicas) cumplieron los criterios para realizar las pruebas de especificación completas. Las puntuaciones oscilaron entre 8 y 12 (de un total de 14), con diferencias en los ámbitos de iluminación, montaje y batería. Solo 2 lámparas proporcionaron > 35000 lux de iluminancia durante la prueba inicial, y ninguna lámpara cumplió con todas las especificaciones mínimas. De las cinco lámparas evaluadas en Etiopía, hubo una gran variabilidad en las opiniones de los cirujanos anotadas en los registros realizados, tanto sobre la calidad de la iluminación (21-92%), como del tamaño del foco (0-92%). En las entrevistas cualitativas surgieron comentarios importantes como la preferencia por un transporte fácil. Los cirujanos buscaban la mejor calidad al precio más razonable (dado que se utilizaban fondos propios para su adquisición) e identificaron el dispositivo menos costoso pero con alto funcionamiento como primera opción. CONCLUSIÓN: El hecho de que ningún dispositivo satisfizo todas las especificaciones predeterminadas y la gran variabilidad de precios fueron los aspectos esenciales que determinaron la elección de los cirujanos. El dispositivo mejor valorado está siendo modificado por el fabricante en función de los comentarios de diseño, para lograr una lámpara quirúrgica asequible y de alta calidad diseñada específicamente para satisfacer las necesidades de entornos con recursos limitados en la mejora la seguridad quirúrgica.

Evaluating the collection, comparability and findings of six global surgery indicators.

BACKGROUND: In 2015, six indicators were proposed to evaluate global progress towards access to safe, affordable and timely surgical and anaesthesia care. Although some have been adopted as core global health indicators, none has been evaluated systematically. The aims of this study were to assess the availability, comparability and utility of the indicators, and to present available data and updated estimates. METHODS: Nationally representative data were compiled for all World Health Organization (WHO) member states from 2010 to 2016 through contacts with official bodies and review of the published and grey literature, and available databases. Availability, comparability and utility were assessed for each indicator: access to timely essential surgery, specialist surgical workforce density, surgical volume, perioperative mortality, and protection against impoverishing and catastrophic expenditure. Where feasible, imputation models were developed to generate global estimates. RESULTS: Of all WHO member states, 19 had data on the proportion of the population within 2h of a surgical facility, 154 had data on workforce density, 72 reported number of procedures, and nine had perioperative mortality data, but none could report data on catastrophic or impoverishing expenditure. Comparability and utility were variable, and largely dependent on different definitions used. There were sufficient data to estimate that worldwide, in 2015, there were 2 038 947 (i.q.r. 1 884 916-2 281 776) surgeons, obstetricians and anaesthetists, and 266·1 (95 per cent c.i. 220·1 to 344·4) million operations performed. CONCLUSION: Surgical and anaesthesia indicators are increasingly being adopted by the global health community, but data availability remains low. Comparability and utility for all indicators require further resolution.

Surgically avertable burden of obstetric conditions in low- and middle-income regions: a modelled analysis.

OBJECTIVE: To quantify the burden of maternal and neonatal conditions in low- and middle-income countries (LMICs) that could be averted by full access to quality first-level obstetric surgical procedures. DESIGN: Burden of disease and epidemiological modelling. SETTING: LMICs from all global regions. POPULATION: The entire population in 2010. METHODS: We included five conditions in our analysis: maternal haemorrhage; obstructed labour; obstetric fistula; abortion(1) ; and neonatal encephalopathy. Demographic and epidemiological data were obtained from the Global Burden of Disease 2010 study. We split the disability-adjusted life years (DALYs) of these conditions into surgically 'avertable' and 'non-avertable' burdens. We applied the lowest age-specific fatality rates from all global regions to each LMIC region to estimate the avertable deaths, assuming that the differences of death rates between each region and the lowest rates reflect the gap in surgical care. MAIN OUTCOME MEASURES: Deaths and DALYs avertable. RESULTS: Of the estimated 56.6 million DALYs (i.e. 56.6 million years of healthy life lost) of the selected five conditions, 21.1 million DALYs (37%) are avertable by full coverage of quality obstetric surgery in LMICs. The avertable burden in absolute term is substantial given the size of burden of these conditions in LMICs. Neonatal encephalopathy constitutes the largest portion of avertable burden (16.2 million DALYs) among the five conditions, followed by abortion (2.1 million DALYs). CONCLUSIONS: Improving access to quality surgical care at first-level hospitals could reduce a tremendous burden of maternal and neonatal conditions in LMICs.

Evaluation of a large-scale donation of Lifebox pulse oximeters to non-physician anaesthetists in Uganda.

Pulse oximetry is widely accepted as essential monitoring for safe anaesthesia, yet is frequently unavailable in resource-limited settings. The Lifebox pulse oximeter, and associated management training programme, was delivered to 79 non-physician anaesthetists attending the 2011 Uganda Society of Anaesthesia Annual Conference. Using a standardised assessment, recipients were tested for their knowledge of oximetry use and hypoxia management before, immediately following and 3-5 months after the training. Before the course, the median (IQR [range]) test score for the anaesthetists was 36 (34-39 [26-44]) out of a maximum of 50 points. Immediately following the course, the test score increased to 41 (38-43 [25-47]); p < 0.0001 and at the follow-up visit at 3-5 months it was 41 (39-44 [33-49]); p = 0.001 compared with immediate post-training test scores, and 75/79 (95%) oximeters were in routine clinical use. This method of introduction resulted in a high rate of uptake of oximeters into clinical practice and a demonstrable retention of knowledge in a resource-limited setting.

Impact of surgical infrastructure and personnel on volume and availability of essential surgical procedures in Liberia.

BACKGROUND: Essential surgical procedures rank among the most cost-effective of all healthcare interventions. The aim of this study was to enumerate surgical volumes in Liberia, quantify surgical infrastructure, personnel and availability of essential surgical procedures, describe surgical facilities, and assess the influence of human resources and infrastructure on surgical volumes. METHODS: An observational countrywide survey was done in Liberia between 20 September and 8 November 2018. All healthcare facilities performing surgical procedures requiring general, regional or local anaesthesia in an operating theatre between September 2017 and August 2018 were eligible for inclusion. Information on facility infrastructure and human resources was collected by interviewing key personnel. Data on surgical volumes were extracted from operating theatre log books. RESULTS: Of 70 healthcare facilities initially identified as possible surgical facilities, 52 confirmed operative capacity and were eligible for inclusion; all but one shared surgical data. A national surgical volume of 462 operations per 100 000 population was estimated. The median hospital offered nine of 26 essential surgical procedures. Unequal distributions of surgical infrastructure, personnel, and essential surgical procedures were identified between facilities. In multivariable regression analysis, surgical human resources (ß = 0·60, 95 per cent c.i. 0·34 to 0·87; P < 0·001) and infrastructure (ß = 0·03, 0·02 to 0·04; P < 0·001) were found to be strongly associated with operative volumes. CONCLUSION: The availability of essential surgical procedures in Liberia is extremely low. Descriptive tools can quantify inequalities, guide resource allocation, and highlight rational investment areas.

ANTECEDENTES: Los procedimientos quirúrgicos esenciales se encuentran entre los más coste-efectivos de todas las intervenciones de salud. El objetivo de este estudio fue enumerar los volúmenes quirúrgicos en Liberia, cuantificar la infraestructura quirúrgica, personal y disponibilidad de procedimientos quirúrgicos esenciales, describir las instalaciones quirúrgicas y evaluar la influencia de los recursos humanos e infraestructura en los volúmenes quirúrgicos. MÉTODOS: Se realizó una encuesta observacional a nivel nacional en Liberia entre el 20 de septiembre y 8 de noviembre de 2028. Todos los centros médicos que realizaban procedimientos quirúrgicos que precisasen anestesia general, regional o local en un quirófano entre septiembre 2017 y agosto 2018 fueron elegibles para su inclusión. La información sobre la infraestructura de las instalaciones y los recursos humanos fue recogida entrevistando a personal clave. Los datos sobre los volúmenes quirúrgicos se extrajeron de los libros de registro de quirófano. RESULTADOS: De 70 centros médicos inicialmente identificados como posibles instalaciones quirúrgicas, 52 confirmaron disponer de capacidad quirúrgica y fueron elegibles para la inclusión; todos menos uno, compartieron los datos quirúrgicos. Se estimó un volumen quirúrgico nacional de 462 operaciones por 100.000 habitantes. El hospital promedio ofrecía nueve de 26 procedimientos quirúrgicos esenciales. Se identificaron distribuciones desiguales de infraestructura quirúrgica, personal y procedimientos quirúrgicos esenciales entre los centros. Se encontró que los recursos humanos quirúrgicos (ß = 0,60, P < 0,001, i.c. del 95% 0,34-0,87) y la infraestructura (ß = 0,029, P < 0,001, i.c. del 95% 0,019-0,039) estaban fuertemente asociadas con los volúmenes quirúrgicos. CONCLUSIÓN: La disponibilidad de procedimientos quirúrgicos esenciales en Liberia es extremadamente bajo. Instrumentos descriptivos pueden cuantificar desigualdades, orientar las decisiones de asignación de recursos y destacar las áreas para una inversión racional.
