Survey of surgical training and experience of associate clinicians compared with medical officers to understand task-shifting in a low-income country.

Background: A workforce crisis exists in global surgery. One solution is task-shifting, the delegation of surgical tasks to non-physician clinicians or associate clinicians (ACs). Although several studies have shown that ACs have similar postoperative outcomes compared with physicians, little is known about their surgical training. This study aimed to characterize the surgical training and experience of ACs compared with medical officers (MOs) in Tanzania. Methods: All surgical care providers in Pwani Region, Tanzania, were surveyed. Participants reported demographic data, years of training, and procedures assisted and performed during training. They answered open-ended questions about training and post-training surgical experience. The median number of training cases for commonly performed procedures was compared by cadre using Wilcoxon rank sum and Student's t tests. The researchers performed modified content analysis of participants' answers to open-ended questions on training needs and experiences. Results: A total of 21 ACs and 12 MOs participated. ACs reported higher exposure than MOs to similar procedures before their first independent operation (median 40 versus 17 cases respectively; P = 0·031). There was no difference between ACs and MOs in total training surgical volume across common procedures (median 150 versus 171 cases; P = 0·995). Both groups reflected similarly upon their training. Each cadre relied on the other for support and teaching, but noted insufficient specialist supervision during training and independent practice. Conclusions: ACs report similar training and operative experience compared with their physician colleagues in Tanzania.

Antecedentes: La falta de cirujanos en determinadas áreas geográficas es flagrante. Una posible solución es el intercambio de tareas, es decir, la delegación de tareas quirúrgicas en personal sanitario no médico o en clínicos asociados (associate clinicians, AC). Si bien varios estudios han demostrado que los AC obtienen resultados postoperatorios similares a los de los médicos, hay poco información acerca de su entrenamiento quirúrgico. Este estudio tuvo como objetivo caracterizar la capacitación quirúrgica y la experiencia de los AC en comparación con los médicos titulados (medical officer, MO) en Tanzania. Métodos: En este estudio, se encuestaron todos los proveedores de atención quirúrgica de la Región de Pwani, Tanzania. Los participantes proporcionaron datos demográficos, años de entrenamiento y número y tipo de procedimientos realizados y a los que se había asistido durante el periodo de capacitación. Además, respondieron a preguntas abiertas sobre el entrenamiento y su experiencia quirúrgica posterior al entrenamiento. Se comparó la mediana del número de procedimientos más realizados por cada grupo mediante la suma de rangos de Wilcoxon y la prueba de la t de Student. Los investigadores realizaron un análisis del contenido de las respuestas a las preguntas abiertas sobre las necesidades y la experiencia durante la etapa de entrenamiento. Resultados: En el estudio participaron 21 ACs y 12 MOs. Los CA estuvieron expuestos a un mayor número procedimientos del mismo tipo antes de efectuar su primera operación de forma independiente en comparación con los OM (40 versus 17 casos, P = 0,031). No hubo diferencias en el volumen operatorio total de los procedimientos comunes entre los AC y los MO (150 versus 171 casos, P = 0,995). Las opiniones de los dos grupos sobre el entrenamiento fueron similares. Los dos grupos se dieron soporte entre ellos, pero quedó patente que la supervisión por parte de un especialista durante el entrenamiento y la práctica independiente era insuficiente. Conclusiones: En Tanzania, los asociados clínicos tienen entrenamientos y experiencias quirúrgicas similares a las de sus colegas médicos.

An estimation of inguinal hernia epidemiology adjusted for population age structure in Tanzania.

PURPOSE: Surgical conditions represent a significant source of global disease burden. Little is known about the epidemiology of inguinal hernia in resource-poor settings. We present a method to estimate inguinal hernia disease burden in Tanzania. METHODS: Using data from the United States National Health and Nutrition Examination Survey (NHANES) prospective cohort study and Tanzanian demographic figures, we calculated inguinal hernia incidence and prevalence in Tanzanian adults under three surgical rate scenarios. Gender-specific incidence figures from NHANES data were adjusted according to Tanzanian population age structure. Hernia duration was adjusted for Tanzanian life expectancy within each age group. RESULTS: The prevalence of inguinal hernia in Tanzanian adults is 5.36% while an estimated 12.09% of men had hernias. Today, 683,904 adults suffer from symptomatic inguinal hernia in Tanzania. The annual incidence of symptomatic hernias in Tanzanian adults is 163 per 100,000 population. At Tanzania's current hernia repair rate, a backlog of 995,874 hernias in need of repair will develop over 10 years. 4.4 million disability-adjusted life-years would be averted with repair of prevalent symptomatic hernias in Tanzania. CONCLUSIONS: Our data indicate the extent of inguinal hernia disease burden in Tanzania. By adjusting our figures for the age structure of Tanzania, we have demonstrated that while the incidence of symptomatic cases may be lower than previously thought, prevalence of inguinal hernia in Tanzania remains high. This approach provides an update to our previously described methodology for calculation of inguinal hernia epidemiology in resource-poor settings that may be used in multiple country contexts.
