Competency Assessment of General Surgery Trainees: A Perspective From the Global South, in a CBME-Naive Context

OBJECTIVE

Before proceeding with local implementation of competency-based medical education-related assessment practices designed and evaluated in the Global North, we sought to challenge the assumption that this would be perceived as both necessary and acceptable in our context where training and assessment is based on a traditional, knowledge-focused approach. The aim of this study was to determine the perspectives of general surgery trainees and consultants towards the assessment of competence, how this has been achieved previously, and how it should be performed in the future at the University of Cape Town (UCT), South Africa.

DESIGN

Semi-structured interviews were conducted with consultants and trainees. Interviews were transcribed and then analyzed using a Reflexive Thematic Analysis approach.

SETTING AND PARTICIPANTS

Ten consultants (5 senior and 5 junior) and 10 trainees (5 South African and 5 international) from the Division of General Surgery at UCT in August 2022.

RESULTS

Five unique themes were developed: (1) Assessment of competence is essential, (2) competence includes multiple domains of practice, (3) a surgeon must be able to operate, (4) previously used methods were inadequate to assess competence, and (5) frequent assessment with feedback is desired. The themes were considered in the context of Situated Learning Theory, particularly Communities of Practice and their role in the training for, and authentic assessment of, competence in general surgery trainees.

CONCLUSIONS

Participants described a need to develop and implement a new competency assessment program for general surgery training in this context, which is aligned with described competency-based medical education principles. Thoughtful integration of the formative and summative use of direct observation in the workplace, with a clear emphasis on procedural ability and the provision of high-quality feedback, may enhance the successful implementation of a strategy for competency-based assessment in general surgery training programs.

The impact of thromboelastography on patients with penetrating abdominal trauma requiring intensive care

BACKGROUND

Trauma-induced coagulopathy (TIC) is a complex multifaceted process which contributes to higher mortality rates in severely injured trauma patients. Thromboelastography (TEG) is effective in detecting TIC which assists in instituting goal-directed therapy as part of damage control resuscitation.

METHODS

This retrospective study included all adult patients over a 36-month period with penetrating abdominal trauma who required a laparotomy, blood products and admission for critical care. Analysis included demographics, admission data, 24-hour interventions, TEG parameters and 30-day outcomes.

RESULTS

Eighty-four patients with a median age of 28 years were included. The majority (93%; 78/84) suffered from a gunshot injury, with 75% (63/84) receiving a damage control laparotomy. Forty-eight patients (57%) had a TEG. Injury severity score and total fluid and blood product administered in the first 24 hours were all significantly higher in patients who had a TEG (p < 0.05). TEG profiles were: 42% (20/48) normal, 42% (20/48) hypocoagulable, 12% (6/48) hypercoagulable and 4% (2/48) mixed parameters. Fibrinolysis profiles were: 48% (23/48) normal, 44% (21/48) fibrinolysis shutdown and 8% (4/48) hyperfibrinolysis. Mortality rate was 5% (4/84) at 24 hours and 26% (22/84) at 30 days, with no difference between the two groups. High-grade complication rates, days on a ventilator and intensive care unit length of stay were all significantly higher in patients who did not have a TEG.

CONCLUSION

TIC is common in severely injured penetrating trauma patients. The usage of a thromboelastogram did not impact on 24-hour or 30-day mortality but did result in a decreased intensive care stay and a decreased high-grade complication rate.

Sentinel lymph node biopsy in a resourcelimited setting: a retrospective comparison of sentinel lymph node biopsy before and after the introduction of Sentimag at an academic breast unit

BACKGROUND

Sentinel lymph node biopsy (SLNB) is performed for staging and prognostication of breast cancer (BC) in cases with a clinically and radiologically negative axilla. Using blue dye and a radioactive colloid injection is considered the gold standard for SLNB. This study aims to evaluate the SLNB outcomes before and after the introduction of Sentimag at an academic breast unit. Sentimag uses an injection of superparamagnetic iron oxide which is then detected in the sentinal lymph node using a magnetometer.

METHODS

A retrospective cohort study was performed comparing SLNBs done from 1 January 2017 to 31 December 2018. During 2017, a nuclear medicine technique was used for all SLNBs, while the Sentimag system was used in 2018.

RESULTS

There was no difference between the two groups comparing age, T-stage, size of tumour, and molecular status. The only statistically significant difference found was more higher-grade tumours in the group where a nuclear medicine technique was used in 2017 (p = 0.04). There was no difference in the type of surgery performed comparing mastectomy and breast-conserving surgery rates between the two groups. There was an 11% increase in the number of patients who had an SLNB done with the Sentimag technique (2018). In 2017, 42% (58/139) had an SLNB and in 2018, 53% (59/112) had an SLNB.

CONCLUSION

This result demonstrates the feasibility of the magnetic technique for SLNB in a resource-limited setting. This new method shows promise as a safe and effective technique for SLNB - it is a valuable alternative in the absence of nuclear medicine (N.Med) facilities.

Strategies for recovery of a surgical service in the COVID-19 era

The COVID-19 pandemic has resulted in a massive backlog of elective cases. Delays in the provision of "elective" surgical care have dire consequences for the patient: progression of disease and comorbidities, higher complication rates, and lower overall survival. Delays in elective surgery also have significant consequences for the health system: added emotional strain on healthcare workers, a reduction in training opportunities, increased costs, and increased inequality in health-service provision. As the virus is likely to become endemic, the recovery of surgical services from the initial shock of the first three waves needs to be carefully planned, in order to mitigate the further loss of elective surgical services. This article presents a narrative review of the latest international guidelines and recommendations pertaining to surgical recovery strategies in the COVID-19 pandemic. To begin with, any recovery plan should be led by a local governance committee, who need to design and implement a number of strategies across the three phases of recovery. The preparation phase includes deciding on a system of case prioritisation, assessing and organising resources, and planning innovative ways to reorganise the service itself. The perioperative phase involves putting measures in place to reduce the risk of COVID-19 transmission. The post discharge phase includes the implementation of telemedicine for follow-up, as well as methods of service audit to enable continuous adjustment and improvement. Surgical service recovery presents many challenges; however, these also present a unique opportunity to reassess and improve the efficiency of surgical care delivery.

Compliance to the South African ventral hernia guidelines: inaugural results from the HIG(SA) registry

BACKGROUND

The Hernia Interest Group (HIG) of South Africa (SA), following the publication of their inguinal and ventral hernia guidelines (in 2015 and 2016 respectively), developed a hernia registry, the HIG(SA) hernia registry.

METHODS

A retrospective analysis of the prospectively maintained HIG(SA) hernia registry from 1 February 2019 to 29 February 2020. Compliance to six recommendations made in the HIG(SA) ventral hernia guidelines were assessed in both the public and private healthcare systems.

RESULTS

Three hundred and fifty-three ventral hernia repair cases were included in the study. Fifty-four per cent were private and 46% were public sector cases. Laparoscopic repair for patients with a BMI > 35 kg/m² occurred in 38% of eligible cases and a minimum 5 cm of mesh overlap was achieved in 50% of cases. Overall, 80% of elective cases occurred in non-smokers; 97% of the intraperitoneal on-lay mesh (IPOM) repairs used composite mesh; 96% of ventral hernias with defects of larger than 2 cm and 95% of incisional hernias were repaired with mesh. Non-smokers undergoing repair numbered 72% in public and 85% in private practice, p = 0.01.

CONCLUSION

Ventral hernia repair practices in SA facilities overall had good compliance to four out of the six HIG(SA) ventral hernia guidelines highlighted for the purposes of this study. The two guidelines that had poor compliance overall were 'laparoscopic repair for patients with a BMI of > 35 kg/m²' and 'ensuring a mesh overlap of 5 cm'. The public sector had higher rates of current smokers undergoing elective ventral hernia repair.

Laparoscopic splenopexy for wandering spleen with absorbable mesh fixation

Wandering spleen is a rare condition characterised by lack of fixation of the spleen to its usual position in the left upper quadrant. Laparoscopic splenopexy has become the standard of care. Although a number of methods have been described, the use of an absorbable mesh to secure the spleen to the left upper quadrant has been shown to be safe, effective and quick to perform. We present a case of a 32-year-old female with this condition and describe our surgical technique for fixation of the spleen using an absorbable mesh.

Global political responsibility for the conservation of albatrosses and large petrels

Migratory marine species cross political borders and enter the high seas, where the lack of an effective global management framework for biodiversity leaves them vulnerable to threats. Here, we combine 10,108 tracks from 5775 individual birds at 87 sites with data on breeding population sizes to estimate the relative year-round importance of national jurisdictions and high seas areas for 39 species of albatrosses and large petrels. Populations from every country made extensive use of the high seas, indicating the stake each country has in the management of biodiversity in international waters. We quantified the links among national populations of these threatened seabirds and the regional fisheries management organizations (RFMOs) which regulate fishing in the high seas. This work makes explicit the relative responsibilities that each country and RFMO has for the management of shared biodiversity, providing invaluable information for the conservation and management of migratory species in the marine realm.

Surgery for Pheochromocytoma: A Single-Center Review of 60 Cases from South Africa

BACKGROUND

There is a paucity of data on the presentation and surgical management of pheochromocytoma in developing nations, particularly in Africa.

METHODS

This study was a retrospective review, which included all patients managed by the Groote Schuur Hospital/University of Cape Town Endocrine Surgery unit for pheochromocytoma and abdominal paragangliomas, from January 2002 to June 2019.

RESULTS

Sixty patients were included in the study, of which 33% were male and 67% female. The mean age was 47 years (range 14-81). The median tumor size was 6 cm, with 45% larger than 6 cm. 92% were located in the adrenal gland (87% unilateral, 5% bilateral), and 8% were extra-adrenal. The conversion rate for laparoscopic cases was 20%, with 55% of cases overall completed laparoscopically. Eleven patients with tumors > 6 cm were initially attempted laparoscopically, of which 3 were converted to open, without any associated increased morbidity. A major adverse event was recorded for 5 cases (8%), including 1 mortality. Overall morbidity, blood loss, operating time and hospital stay were all significantly reduced in the laparoscopic group. There were 5 patients with malignant disease (8%).

CONCLUSION

This large series, from an established academic endocrine surgery unit in Africa, can serve as a benchmark for units with similar settings and resource limitations, to compare their surgical management and perioperative outcomes.

Protective effect of hydroxysafflor yellow A on dopaminergic neurons against 6-hydroxydopamine, activating anti-apoptotic and anti-neuroinflammatory pathways

CONTEXT

Hydroxysafflor yellow A (HSYA) has been shown to have neuroprotective effects in cerebral infarction. However, its underlying roles in apoptosis and inflammation in Parkinson's disease (PD) are unknown.

OBJECTIVE

The present study investigates the effects and underlying mechanisms of HSYA on dopaminergic (DA) neurodegeneration, inflammation, and apoptosis.

MATERIALS AND METHODS

The PD model was established by 2 μL of 6-hyroxydopamine (6-OHDA) (3 μg/μL) striatal injection in C57BL/6J mice with different doses of HSYA (2, 4, or 8 mg/kg). In vitro, after being treated with HSYA for 1 h, SH-SY5Y cells were exposed to 6-OHDA for 24 h before analysis. Expression of tyrosine hydroxylase (TH) in substantia nigra (SN) and corpus striatum (STR) was evaluated by immunohistochemistry (IHC) and western blot. In addition, apoptosis-related and inflammatory proteins were examined by western blot.

RESULTS

Administration of HSYA significantly reduced the Apomorphine (APO)-induced rotation, decreased from 122.5 ± 15.1 (6-OHDA group) to 47.2 ± 14.3 (8 mg/kg HSYA group). HSYA partially restored a deficit in the SN and STR of PD mice brains in TH. Furthermore, western blot analysis revealed that HSYA reduced inflammatory proteins, including iNOS, COX-2 and NF-κB and attenuated the elevation of DA neuronal apoptosis observed in PD. In vitro assays showed that HSYA reduced the levels of p-p38 and p-JNK and increased that of p-ERK in 6-OHDA-leisoned SH-SY5Y cells.

CONCLUSIONS

These findings indicate that HSYA protects against 6-OHDA induced DA neurodegeneration partly by regulating the MAPK inflammatory signalling pathway and apoptosis which highlight its therapeutic potential in the treatment of PD.

Disparity in oesophageal cancer management in South Africa: a comparison between two tertiary centres with special focus on the palliation of dysphagia

BACKGROUND

For most patients with oesophageal cancer worldwide, palliation of dysphagia is the goal which is most commonly achieved with self-expanding metal stents (SEMS). The aim of this study was to assess the profile and management of oesophageal cancer patients at Frere Hospital in the Eastern Cape, and compare this to a similar cohort from Groote Schuur Hospital (GSH) in the Western Cape Province.

METHOD

This study is a retrospective comparative cohort which reviewed all patients diagnosed with oesophageal cancer by the Frere Hospital and GSH endoscopy units from January to December 2015. Independent prospective electronic databases for the two hospitals were merged for comparative analysis.

RESULTS

During the study period, 346 and 108 patients were diagnosed with oesophageal cancer at Frere Hospital and GSH respectively. The rate of curative intended intervention was similarly low, with 3% of cases at Frere Hospital undergoing oesophagectomy or definitive radiotherapy as compared to 5% at GSH (p=0.48). In terms of palliation, significantly more patients received palliative oncological therapy at GSH as compared to Frere Hospital (21% vs 8%, p < 0.001). At Frere Hospital, 281 patients (81%) were treated primarily with serial dilatations. At GSH, 9 patients received a single dilatation, all as a bridge to radiotherapy or stenting. At Frere Hospital, 28 patients (8%) were stented, as compared to GHS where 69 patients (64%) were managed with a stent (p < 0.001).

CONCLUSION

This study shows significant differences in the oncological and endoscopic palliation of patients between the two institutions, highlighting a gross disparity in healthcare provision between them. The reasons for these disparities should be investigated and equipoise addressed by national health policy makers.

Slow early graft function: a neglected entity after renal transplantation

BACKGROUND

After renal transplantation, early graft function (EGF) can be divided into delayed graft function (DGF), slow graft function (SGF) and immediate graft function (IGF). DGF is well documented. However, when evaluating the long-term significance of early function, the literature shows conflicting definitions and inconsistent results. In addition, SGF, a new entity separate to DGF and IGF, is a recent and poorly understood development.

AIM

To investigate the risk factors for and the impact of poor EGF (PEGF) on long-term outcome.

METHODS

This retrospective study reviewed the records of local adult patients who underwent renal transplantation at the Groote Schuur Hospital (Cape Town, South Africa) between 2004 and 2008. EGF was divided according to day 5 serum creatinine into IGF (serum creatinine <150 µmol/l), SGF (serum creatinine >150 but <450 µmol/l) and DGF (serum creatinine >450 µmol/l or dialysis in the first week). DGF and SGF together comprised PEGF, with IGF alone representing good EGF (GEGF).

RESULTS

A total of 121 patients (77 men, 44 women; mean age 39 years, range 14-67) were included in the study. Eighteen were excluded due to nephrectomy (n = 8), death (n = 6) or loss to follow-up (n = 4) within the first year. Analysis of cadaveric donors showed no significant risk factors for PEGF with the exception of cold ischaemic time, which differed significantly between the GEGF and PEGF groups, with means of 12 and 16 h, respectively (p = 0.013). Considering both living and cadaveric grafts, the 1-year estimated glomerular filtration rate (eGFR) was significantly different between IGF and DGF (p = 0.038) as well as between IGF and SGF (p = 0.028), with no significant difference between SGF and DGF (p > 0.05). A comparison of the PEGF and GEGF groups yielded significantly different 1-year eGFR values (60 and 50 ml/min, respectively; p = 0.07), with PEGF also associated with a longer hospital stay (20 vs. 14 days; p = 0.00005). Acute rejection was independently associated with a lower 1-year eGFR (p = 0.028), but in the absence of rejection, GEGF and PEGF remained significantly different with regards to 1-year eGFR (p = 0.024).

CONCLUSIONS

SGF is not related to IGF but rather to DGF and should thus be regarded as a form of PEGF as opposed to GEGF. PEGF has a worse long-term outcome, and this indicates the need for increased efforts in its prevention and greater attention to its management.

Online Communication of Brand Personality

Brand personality has often been considered from the perspective of products, corporate brands or countries, but rarely among service offerings. Moreover, there remains the consideration of how these entities are communicated online. This article explores the brand personality dimensions that business schools communicate and whether they differ in putting across clear and distinctive brand personalities in cyberspace. Three clusters from the Financial Times’ top 100 full-time global MBA programs in 2005 are used to undertake a combination of computerised content and correspondence analyses. The content analysis was structured using Aaker's Rve-dimensional framework whilst the positioning maps were produced by examining the data using correspondence analysis. Results indicate that some schools have clear brand personalities while others fail to communicate their brand personalities in a distinct way. This study also illustrates a powerful, but simple and relatively inexpensive way for organisations and brand researchers to study the brand personalities actually being communicated.

Trusting Relationships and Personal Acquaintance: Implications for Business Friendships

Friendship is very often a component of business relationships. Organisations frequently have relationships with their suppliers, customers and collaborators that could be described as ‘friendly’. However, there is little comparative evidence concerning the extent to which business friendships resemble true social friendships. This article illustrates some differences that may exist between social and business friendships, with particular reference to the extent that interpersonal relationships are trusting, and are based on the nature of personal acquaintance. This means that managers need to understand the differences between business and personal friendships and adjust the type of interactions they, and those who report to them, have with customers, suppliers, collaborators, and the like.

Health care quality in NHS hospitals

Hospitals provide the same type of service, but they do not all provide the same quality of service. No one knows this better than patients. Reports the results of a market research exercise initiated to ascertain the different factors which patients of health care identify as being necessary to provide error-free service quality in the NHS hospitals. To measure patients' satisfaction with NHS hospitals, the internationally-used market research technique called SERVQUAL was used in order to measure patients' expectations before admission, record their perceptions after discharge from the hospital, and then to close the gap between them. This technique compares expectations with perceptions of service received across five broad dimensions of service quality, namely: tangibility; reliability; responsiveness; assurance; and empathy. This analysis covered 174 patients who had completed the SERVQUAL questionnaire, including patients who had had treatment in surgical, orthopaedic, spinal injury, medicinal, dental and other specialties in the West Midlands region. Recorded the average weighted NHS service quality score overall for the five dimensions as significantly negative.

Service quality in NHS hospitals

Discusses the utilization of an instrument--SERVQUAL--as a means of assessing patient satisfaction with service quality. Patients treated (174) for a variety of health problems in a number of departments completed the SERVQUAL questionnaire. There is a dearth of knowledge in this important field and the authors note that the results indicate the need for improvement in service quality as identified by the study population.

User Satisfaction and Service Quality of the IS Department: Closing the Gaps

Measurement and management of user satisfaction with information systems (IS) have been issues of concern for practitioners and academics in the field for some time. This paper introduces the ‘Gaps’ approach to service quality, a topic widely discussed in the marketing literature, and proposes that a similar approach is applicable in the IS domain. The user gap is explained and its measurement suggested, and the other gaps within the IS arena are described and their causes and cures addressed.

Computer-based prescription audit as a research, educational and management tool

An existing dedicated pharmacy computer system (MIDAS system, Alfred Hospital and Health Computing Services, Victoria) used primarily for pharmacy labelling and dispensing, has been rewritten for an in-house minicomputer, with enhancements that allow it to be used in budgetary predictions, drug use monitoring, therapeutic audit and as a research tool. An automatically updated hard copy record of individual patient prescription profiles is generated and represents a valuable addition to the patient medical record. Allied to automatic "sorting" and retrieval techniques, all patients on nominated drugs can be identified and their records examined for particular combination use. Current application to assessment of nifedipine- beta blocker use will be presented, as will an application to cimetidine audit. Prescriptions can be scanned and segregated in terms of numbers of prescriptions in addition to segregation in terms of a particular therapeutic agent. Initial application to audit has detected an unacceptable level of polypharmacy (more than 26% of all prescriptions involve greater than or equal to 5 items and more than 3% involved greater than or equal to 10 items). Statistical information on the volume and unit cost of outpatient prescribing allows a precise estimate of ongoing budgetary commitments, while trends in discharge medication profiles allow a basis for prediction of budgetary trends, particularly with respect to the use of recent additions to the formulary. The system allows for expansion at minimal cost with potentially revolutionary applications, for example, interactive prescriber education if and when "on-line" capabilities are developed. Cross-linking with relevant data-bases will allow a major expansion of applied research into therapeutic drug use and its consequences.

[The influence of sports injuries on sport participation and work]

The incidence and complications of sport injuries in athletics, basketball, gymnastics, hockey, netball, cricket, tennis and soccer were analysed from questionnaire responses of 239 sport participants in Pretoria. Lower limb injuries were most common (73%). Torn tendomuscular organs represented 29,3% of the total number of injuries; sprains, strains and dislocations 35,9%; and fractures 20,5%. Medical treatment was sought by 62,8% of the patients. A total of 60,7% of the subjects was advised to suspend further participation in sport, but 30,6% failed to do so and more than half of these again sustained injuries. Those who were booked off from work totalled 18,0%, but a further 4,5% stayed away from work voluntarily.
