RESUMO

Objective: To assess the impact of an open fracture intervention bundle on clinical management and patient outcomes of adults in Malawi with open tibia fractures. Methods: We conducted a before-and-after implementation study in Malawi in 2021 and 2022 to assess the impact of an open fracture intervention bundle, including a national education course for clinical officers and management guidelines for open fractures. We recruited 287 patients with open tibia fractures. The primary outcome was a before-and-after comparison of the self-reported short musculoskeletal function assessment score, a measure of patient function. Secondary outcomes included clinical management; and clinician knowledge and implementation evaluation outcomes of 57 health-care providers attending the course. We also constructed multilevel regression models to investigate associations between clinical knowledge, patient function, and implementation evaluation before and after the intervention. Findings: The median patient function score at 1 year was 6.8 (interquartile range, IQR: 1.5 to 14.5) before intervention and 8.4 (IQR: 3.8 to 23.2) after intervention. Compared with baseline scores, we found clinicians' open fracture knowledge scores improved 1 year after the intervention was implemented (mean posterior difference: 1.6, 95% highest density interval: 0.9 to 2.4). However, we found no difference in most aspects of clinicians' open fracture management practice. Conclusion: Despite possible improvement in clinician knowledge and positive evaluation of the intervention implementation, our study showed that there was no overall improvement in clinical management, and weak evidence of worsening patient function 1 year after injury, after implementation of the open fracture intervention bundle.

RESUMO

Background: Open fractures, a common consequence of road traffic collisions, are associated with a high risk of complications. The introduction of standard guidelines has been shown to improve patient care and reduce the risk of complications in several countries. In September 2021, the Malawi Orthopaedic Association/Arbeitsgemeinschaft für Osteosynthesefragen Alliance (MOA/AOA) guidelines and standards for open fracture management were introduced in Malawi. This study aimed to assess the management of open fractures in hospitals in Malawi, before and after implementing a training course on the MOA/AOA open fracture guidelines. Methods: This was a descriptive and quantitative, before-and-after study that reviewed the medical files of patients with open fractures at Zomba Central Hospital and Mulanje, Salima, and Mangochi district hospitals over two 3-month periods. Variables included initial assessment; antibiotic prophylaxis; place of debridement; type of anesthesia; treatment of the open fracture in the emergency department, operating room, and wards; and short-term complications requiring hospital treatment. Results: A total of 88 open-fracture case files were reviewed; 43 were prior and 45 were subsequent to the implementation of the open fracture guidelines. The overall median patient age was 36 years (interquartile range, 27 to 45 years), and 91% (80) were male. Limb neurovascular status assessment and documentation improved from 26% (11) of the patients before the guidelines to 62% (28) afterward (p = 0.0002). The percentage who underwent debridement in the operating room significantly increased from 19% (8) to 69% (31) (p = 0.01). The percentage who underwent debridement under general or spinal anesthesia significantly increased from 5% (2) to 38% (17) and from 12% (5) to 29% (13), respectively (p= 0.001). The wound infection rate decreased from 21% to 11%, but this was not significant, and there was no change in the overall complication rate (p = 0.152). Conclusions: This study suggests that training on the MOA/AOA open fracture management guidelines followed by their implementation can lead to at least temporary improvement in the management of open fractures. Nevertheless, additional studies need to be performed to understand the effect on long-term patient outcomes. Levels of Evidence: Therapeutic Level III. See Instructions for Authors for a complete description of levels of evidence.

RESUMO

PURPOSE: To assess the impact of the COVID-19 pandemic on the outcomes of the patients who underwent trauma surgery during the peak of the pandemic. METHODS: The UKCoTS collected the postoperative outcomes of consecutive patients who underwent trauma surgery across 50 centres during the peak of the pandemic (April 2020) and during April 2019. RESULTS: Patients who were operated on during 2020 were less likely to be followed up within a 30-day postoperative period (57.5% versus 75.6% p <0.001). The 30-day mortality rate was significantly higher during 2020 (7.4% versus 3.7%, p <0.001). Likewise, the 60-day mortality rate was significantly higher in 2020 than in 2019 (p <0.001). Patients who were operated on during 2020 had lower rates of 30-day postoperative complications (20.7% versus 26.4%, p <0.001). CONCLUSIONS: Postoperative mortality was higher during the first wave of the COVID-19 pandemic compared to the same period in 2019, but with lower rates of postoperative complications and reoperation.

RESUMO

BACKGROUND: A key strategy to building surgical capacity in low income countries involves training care providers, particularly in the interventions highlighted by the Lancet Commission for Global Surgery, including the management of open fractures. This is a common injury, especially in areas with a high incidence of road traffic incidents. The aim of this study was to use a nominal group consensus method to design a course on open fracture management for clinical officers in Malawi. METHODS: The nominal group meeting was held over two days, including clinical officers and surgeons from Malawi and the UK with various levels of expertise in the fields of global surgery, orthopaedics and education. The group was posed with questions on course content, delivery and evaluation. Each participant was encouraged to suggest an answer and the advantages and disadvantages of each suggestion were discussed before voting through an anonymous online platform. Voting included use of a Likert scale or ranking available options. Ethical approval for this process was obtained from the College of Medicine Research and Ethics Committee Malawi and the Liverpool School of Tropical Medicine. RESULTS: All suggested course topics received an average score of greater than 8 out of 10 on a Likert scale and were included in the final programme. Videos was the highest ranking option as a method for delivering pre-course material. The highest ranking methods for each course topic included lectures, videos and practicals. When asked what practical skill should be tested at the end of the course, the highest ranking option was "initial assessment". CONCLUSION: This work outlines how a consensus meeting can be used to design an educational intervention to improve patient care and outcomes. Through combining the perspectives of both the trainer and trainee, the course aligns both agendas so that it is relevant and sustainable.

RESUMO

OBJECTIVES: To investigate the impact of COVID-19 on the well-being of surgeons and allied health professionals as well as the support provided by their institutions. DESIGN: This cross-sectional study involved distributing an online survey through medical organisations, social media platforms and collaborators. SETTING: It included all staff based in an operating theatre environment around the world. PARTICIPANTS: 1590 complete responses were received from 54 countries between 15 July and 15 December 2020. The average age of participants was 30-40 years old, 64.9% were men and 32.5% of a white ethnic background. 79.5% were surgeons with the remainder being nurses, assistants, anaesthetists, operating department practitioners or classified other. MAIN OUTCOME MEASURES: Participants that had experienced any physical illness, changes in mental health, salary or time with family since the start of the pandemic as well as support available based on published recommendations. RESULTS: 32.0% reported becoming physically ill. This was more likely in those with reduced access to personal protective equipment (OR 4.62; CI 2.82 to 7.56; p<0.001) and regular breaks (OR 1.56; CI 1.18 to 2.06; p=0.002). Those with a decrease in salary (29.0%) were more likely to have an increase in anxiety (OR 1.50; CI 1.19 to 1.89; p=0.001) and depression (OR 1.84; CI 1.40 to 2.43; p<0.001) and those who spent less time with family (35.2%) were more likely to have an increase in depression (OR 1.74; CI 1.34 to 2.26; p<0.001). Only 36.0% had easy access to occupational health, 44.0% to mental health services, 16.5% to 24/7 rest facilities and 14.2% to 24/7 food and drink facilities. Fewer measures were available in countries with a low Human Development Index. CONCLUSIONS: This work has highlighted a need and strategies to improve conditions for the healthcare workforce, ultimately benefiting patient care.

RESUMO

BACKGROUND: A robust health care system providing safe surgical care to a population can only be achieved in conjunction with access to competent surgical personnel. It has been reported that 5 billion people do not have access to safe, affordable surgical and anaesthesia care when needed. This study aims to fill the existing gap in evidence by quantifying shortfalls in trained personnel delivering safe surgical and anaesthetic care in low- and middle-income countries (LMICs) according to the type of health care facility. METHODS: We conducted secondary analysis of 1323 health facilities, in 35 low- and middle-income countries using facility-based cross-sectional data from the World Health Organization Situational Analysis Tool to Assess Emergency and Essential Surgical Care. RESULTS: The majority of surgical and anaesthetic care in LMICs was provided by general doctors (range 13.8-41.1%; mean 27.1%). Non-physicians made up a significant proportion of the surgical workforce in LMICs. 26.76% of the surgical and anaesthetic workforce was provided by clinical medical officers and nurses. Private/NGO/mission hospitals, large, well-resourced institutions had the highest proportion of surgeons compared to any other type of health care facility at 27.92%. This compares to figures of 18.2 and 19.96% of surgeons at health centres and subdistrict/community hospitals, respectively, representing the lowest level of health facility. CONCLUSIONS: We highlight the significant proportion of non-physicians delivering surgical and anaesthetic care in LMICs and illustrate wide variations according to the type of health care facility.

RESUMO

Trauma disproportionately affects low- and middle-income countries, many of which do not have the surveillance systems required to design effective prevention and treatment strategies. The aim of this study was to establish such a system at a district hospital in Malawi. Data on all trauma patients presenting to Mulanje District Hospital from 14 April 2013 to 30 December 2014 were collected using a form based on the core minimum data points for injuries recommended by the World Health Organization and an injury severity assessment. A total of 9073 trauma cases were recorded, accounting for 3.4% of patients that presented at the hospital during this period. Of them, 56.6% were boys/men, with the average age being 22.4 (range, 0.6-98 years). Falls (53.2%), animal bites (16.6%), road traffic injuries (11.1%) and assaults (10.2%) were the most prevalent causes, the majority of the former two taking place at home. Of the patients, 94.8% were treated and sent home, 5.0% were admitted and the remaining were either referred elsewhere or died.

RESUMO

OBJECTIVE: Pelvic lymph node dissection (PLND) is performed alongside radical prostatectomy as the most accurate method of staging prostate cancer. Yet the potential therapeutic benefits of lymphadenectomy are yet to be confirmed. MATERIAL AND METHODS: A PubMed database search was performed to identify all papers comparing techniques for PLND or none. The primary outcome measure was long term oncological outcomes. Studies looking at men with clinically localized prostate cancer at the time of radical prostatectomy who received no adjuvant treatment were included. Previous reviews and single case reports were excluded. The subsequent available papers were then systematically reviewed. RESULTS: Limited PLND provides no benefit in low risk prostate cancer and is unlikely to provide a therapeutic benefit in higher risk groups either when compared with no PLND. Extended PLND may provide some therapeutic benefit, particularly in patients with occult metastases; however, the evidence base for this is not particularly strong and may be down to statistical phenomena. CONCLUSION: When performed in prostate cancer patients, PLND should be extended, as it is a more accurate staging tool and may provide therapeutic benefit to some patients. However, to properly assess this, randomised controlled studies need to be performed in this area.

RESUMO

BACKGROUND: The technical reliability demonstrated by semi active robots in implant placement could render unicompartmental knee arthroplasties (UKAs) more favourable than they are currently. The relatively untested method using patient specific instrumentation (PSI), however, has the potential to match the accuracy produced by robots but without the barriers that have prevented them from being used more widely in clinical practice, namely operative time. Therefore this study took a step towards comparing the accuracy and time taken between the two technologies. METHODS: Thirty-six UKAs were carried out on identical knee models, 12 with the Sculptor, 12 with PSI and 12 conventionally under timed conditions. Implant placement in these knees was then judged against that in a pre-operative plan. RESULTS: Tibial implant orientations and femoral implant positions and orientations were significantly more accurate in the PSI group with mean errors of 6°, 2 mm and 4° respectively, than the conventional group which had means of 9°, 4 mm and 10°. There was no significant difference between the robot and PSI generally except in tibial implant orientation (mean robotic error 3°) and tibial implant position did not vary significantly across all three groups. It was also found that use of PSI and conventional methods took half the time taken by the robot (p<0.001). CONCLUSIONS: With further development, PSI can match and possibly surpass the accuracy of the robot, as it does with the conventional method, and achieve planned surgery in less time. CLINICAL RELEVANCE: This work sets the foundation for clinical trials involving PSI.

RESUMO

In recent years, robots have become commonplace in surgical procedures due to their high accuracy and repeatability. The Acrobot Sculptor is an example of such a robot that can assist with unicompartmental knee replacement. In this study, we aim to evaluate the accuracy of the robot (software and hardware) in a clinical setting. We looked at (1) segmentation by comparing the segmented data from Sculptor software to other commercial software, (2) registration by checking the inter- and intraobserver repeatability of selecting set points, and finally (3) sculpting (n = 9 cases) by evaluating the achieved implant position and orientation relative to that planned. The results from segmentation and registration were found to be accurate. The highest error was observed in flexion extension orientation of femoral implant (0.4 ± 3.7°). Mean compound rotational and translational errors for both components were 2.1 ± 0.6 mm and 3 ± 0.8° for tibia and 2.4 ± 1.2 mm and 4.3 ± 1.4° for the femur. The results from all processes used in Acrobot were small. Validation of robot in clinical settings is highly vital to ensure a good outcome for patients. It is therefore recommended to follow the protocol used here on other available similar products.

RESUMO

Robotic systems have been shown to improve unicompartmental knee arthroplasty (UKA) component placement accuracy compared to conventional methods when used by experienced surgeons. We aimed to determine whether inexperienced UKA surgeons can position components accurately using robotic assistance when compared to conventional methods and to demonstrate the effect repetition has on accuracy. Sixteen surgeons were randomised to an active constraint robot or conventional group performing three UKAs over three weeks. Implanted component positions and orientations were compared to planned component positions in six degrees of freedom for both femoral and tibial components. Mean procedure time decreased for both robot (37.5 mins to 25.7 mins) (P = 0.002) and conventional (33.8 mins to 21.0 mins) (P = 0.002) groups by attempt three indicating the presence of a learning curve; however, neither group demonstrated changes in accuracy. Mean compound rotational and translational errors were lower in the robot group compared to the conventional group for both components at all attempts for which rotational error differences were significant at every attempt. The conventional group's positioning remained inaccurate even with repeated attempts although procedure time improved. In comparison, by limiting inaccuracies inherent in conventional equipment, robotic assistance enabled surgeons to achieve precision and accuracy when positioning UKA components irrespective of their experience.
