Filter by:Access to safe surgery is a basic human right. This is highlighted by the work of the Lancet Commission on Global Surgery. There is a large burden of surgical disease in the paediatric surgical population with a large unmet need. In Africa, children comprise a significant proportion of the population with approximately 50% of the population being ≤19 years old. Limited data from Africa suggests the risk factors for, incidence and outcomes associated with paediatric surgical complications differ from HICs. The African Surgical Outcomes Study (ASOS) has described surgical outcomes in adult patients in Africa. There is a need to determine the burden of the complications in paediatric surgical patients in Africa, and the risk factors for and the type of complications experienced. Once this study is completed, the investigators will be able to target appropriate interventions to improve surgical outcomes for children in Africa. The investigators have the capacity to do this important work, through the African Perioperative Research Group (APORG) group.
Since the 2000s, many prognostic scores were developed to predict traumatic haemorrhage. Most of these studies were retrospectives based on registers. Due to missing data on death due to bleeding, these studies chose to predict the massive transfusion risk as a surrogate of haemorrhagic death. These scores include clinical parameters (vital signs), laboratory values (Haemoglobin, lactate, Base excess) and/or imaging (CT or ultrasound) values. The scores showing best performance are the Trauma Associated Severe Haemorrhage (TASH) score, developed and validated on the German register (DGU-Register) and the ABC score developed and validated in the United States of America. However, the majority of these scores cannot be applied at the trauma scene due to the unavailability of laboratory and imaging values. Therefore, their clinical utility remains unclear. To overcome the need for diagnostic tests, authors have developed and recently validated a clinical prognostic score in identifying trauma patients with, or at risk of, significant haemorrhage based on predicted probabilities of death due to bleeding: BATT score. This score was developed from an international cohort using data from 271 Trauma Centres in 41 countries on 5 continents and uses first clinical parameters at initial assessment. The BATT score predicts death due to bleeding and has been validated on a large population in England and Wales. It could also predict massive transfusion, as a surrogate of haemorrhagic death, earlier at the trauma scene. Its feasibility and external validation would make its clinical utility superior to other scores while identifying a greater number of patients requiring early management. Our study is an external validation of pre-existing prognostic scores of traumatic haemorrhages (TASH , ABC and BATT score) at different times of care (Scene of Injury, admission at the trauma room) in order to assess their overall performance, discrimination and calibration in the prediction of massive transfusion, and haemorrhagic death. The objective of the study is to assess a comparison of score performances (Overall performance, discrimination and calibration). Due to the study population (STR), which is partly integrated into the German DGU-Register, the investigators expect good transportability of the TASH score to the Swiss Trauma Registry in terms of overall performance, discrimination and calibration. The ABC score should show lowers results in terms of discrimination due to its validation on small cohorts exclusively in North America. The new BATT score predicting death due to bleeding has been validated on a large English cohort of more than 100,000 patients. It identifies all patients with haemorrhage and not only patients who have received a massive transfusion subject to survival bias. In this context, the BATT score provides good discrimination with only simple physiological variables available at the trauma scene. In case of its external validation on the STR as part of our study, its feasibility would make its clinical utility superior to other pre-existing scores, while identifying a greater number of patients requiring early management. Its application would activate a massive transfusion plan directly at the trauma scene and save precious time.
There are few data of paediatric peri-operative morbidity and mortality in South Africa. There is little information on the burden or profile of surgical disease in the paediatric population, the level of anaesthesia or surgical care (specialist versus non-specialist) for paediatric patients, the quality of peri-operative care or contributing factors to poor outcomes. In order to understand current paediatric peri-operative morbidity and mortality in South Africa, it is important to start obtaining these data. Risk factors can be identified and changes can be in implemented accordingly to improve future outcomes. The study will take place over fourteen-days. It is a South African national multi-centre prospective cohort study of paediatric patients (<16 years) undergoing surgery. The SAPSOS study (as was the South African Surgical Outcomes Study (SASOS) study) will be based on the methodology of the European Surgical Outcomes Study (EuSOS). This study has important public health implications for South Africa as surgery is now recognized internationally as an essential part of public health, yet still needs to be defined as a priority in South Africa. Policy-makers and healthcare providers need evidence to plan resource allocation in a way that will improve quality and outcomes. The data from SAPSOS and SASOS, would provide a platform for government and health care providers in South Africa to appropriately allocate funding, make policy decisions and plan future peri-operative healthcare in South Africa.
We observed in a randomised intervention trial in Bissau that mortality due to malaria could be reduced by half by adding a small monetary incentive to the staff and strict follow-up of a standard protocol for available drugs. The Government and donors are not able to sustain such incentives. We intend to evaluate whether strict organisation of a cost recovery system and the use of part of the funds for staff incentives would improve performance of the staff and contribute to reduction of hospital and post-discharge mortality.
