Mentorship during undergraduate surgical training: comparing perceptions of medical students and faculty at two institutions in South Africa and Sweden

BACKGROUND

Having a mentor during undergraduate surgical training has been shown to positively influence medical students by increasing interest in surgery, improving confidence, and assisting in career planning. This study aimed to evaluate and compare medical student and faculty perceptions of mentorship during undergraduate surgical training and compare results between two teaching institutions in South Africa and Sweden.

METHODS

An electronic, online questionnaire was anonymously distributed to medical students and general surgical faculty at the University of Cape Town (UCT), South Africa, and Karolinska Institutet (KI), Stockholm, Sweden. The questionnaire consisted of multiple choice, true or false, and five-point Likert scale questions, exploring perceptions of mentorship and role models, as well as rating the most important mentor characteristics.

RESULTS

Approximately one third (34.2%) of students stated they had a mentor during their surgical training, with significant differences found between student cohorts (p < 0.001). The 'registrar' was most commonly reported as the best role model for medical students by faculty from both UCT (50.0%) and KI (69.4%), as well as UCT students (36.6%). Students rated the following mentor qualities significantly higher compared to faculty: student encouragement (p = 0.037), adequate supervision (p = 0.007), setting of fair expectations (p = 0.002), and teaching skills (p = 0.010).

CONCLUSION

With significant differences existing in the perceptions of medical students and faculty regarding mentorship and role models during undergraduate surgical training in both South African and Swedish institutions, reconciling and harmonising these differences will be crucial in fostering constructive mentoring relationships.

Outcome Measurement at a Ugandan Referral Hospital: Validation of the Mbarara Surgical Services Quality Assurance Database

BACKGROUND

Five billion people lack access to surgery. Accurate and complete data have been identified as essential to the global scale-up of perioperative care. This study retrospectively validates the Mbarara Surgical Services Quality Assurance Database (SQUAD), an electronic outcomes database at a Ugandan secondary referral hospital.

METHODS

SQUAD data were compared to paper records from August 2013 to January 2017. To assess data entry accuracy, two researchers independently extracted 24 patient variables from 170 charts. To assess completeness of patient capture, SQUAD entries were compared to a sample of charts returned to the Medical Records Department, and to a sample of entries in ward and operating room logbooks. Two-tailed binomial proportions with 95% CI were calculated from the comparative results of patient observations, against a predefined accuracy of 0.85-0.95.

RESULTS

Agreement between completed validation observations from charts and SQUAD data was 91.5% (n = 3734/4080 data points). Binomial tests indicated that 15 variables had higher than 95% accuracy. A total 19 of 24 variables had ≥ 85% accuracy. The completeness of SQUAD patient capture was 98.2% (n = 167/170) of charts returned to the Medical Records Department, 97.5% (n = 198/203) of operating logbook entries, and 100% (n = 111/111) of ward logbook entries, respectively.

CONCLUSION

SQUAD closely reflects the primary surgical and anaesthetic data at a Ugandan secondary hospital. Data accuracy of key variables and completeness of population capture were comparable to those of databases in high-income countries and outperformed those of other low- and middle-income countries.

Pitfalls and challenges associated with phenoconversion in forensic toxcicology

PURPOSE

In recent years, several publications have demonstrated the interest and the usefulness of pharmacogenetics in forensic toxicology. However, this approach remains namely focused on DNA-based phenotype, which may potentially lead to misinterpretation. Other determinants such as co-medication or physiological parameters may also impact the phenotype. This article aims to highlight the importance of considering such determinants in forensic toxicology, through the original case of a heroin-related fatality.

METHOD

Ethanol concentration determination and toxicological screening were performed using gas chromatography with flame ionization detection, liquid chromatography with diode array detection and gas chromatography with mass spectrometry detection. CYP2C19 and CYP2D6 genotypes were determined by Taqman® real-time PCR analyses.

RESULTS

Femoral blood analyses revealed the presence of ethanol, morphine, codeine, venlafaxine (VEN), O-desmethylvenlafaxine (ODV) and N-desmethylvenlafaxine (NDV), paroxetine, and risperidone. 6-acetylmorphine was also identified in urine. VEN, paroxetine and risperidone were quantified at supra-therapeutic or toxic blood concentrations. NDV was not quantified. The metabolic ratio of VEN (ODV to VEN) was exceptionally low (about 0.7). Pharmacogenetics testing showed that the patient was heterozygous for the CYP2C19*2 loss-of-function allele, which predict an intermediate metabolism for CYP2C19. None of the deficient CYP2D6 alleles investigated were identified. Those results suggest an extensive CYP2D6-metabolism phenotype.

CONCLUSION

A discrepancy was seen between the results of the genomic evaluation and the observed metabolic ratio of VEN. This tends to exclude a genetic origin and lead us to formulate other hypotheses, such as phenoconversion that may have been induced by drug interaction involving patients' regular medications. Phenoconversion is as a complex phenomenon that leads to genotype-phenotype mismatch without any genetic abnormality particularly described for cytochromes P450 2D6 and 2C19. Although transient, phenoconversion can have a significant impact on the analysis and interpretation of genotype-focused clinical outcomes correlation and in forensic toxicology conclusions.

Baclofen overdose following recreational use in adolescents and young adults: A case report and review of the literature

Over the past twenty years, psychotropic drug abuse by young people, especially by teenagers, has received special attention. Here, we present the case of baclofen overdose in a 16-year-old male who recreationally, and probably recurrently, self-administered baclofen. In addition, a review of other cases was conducted. The 16-year-old boy presented to emergency department with digestive signs followed by agitated confusion. Detection and determination of baclofen concentration were achieved using liquid chromatography tandem mass spectrometry. Baclofen was detected in plasma and urine, at 420 ng/mL and 64 900 ng/mL respectively. Further, an English exhaustive literature search was performed using several different scientific databases without any limiting period in order to identify scientific articles dealing with baclofen overdose following a recreational use among adolescent and young adults. Five publications describing baclofen overdoses following a recreational use among adolescents and young adults have been published reporting19 cases, all involving a non-fatal overdose, with baclofen concentrations ranging from less than 20-1322 ng/mL. Baclofen is a psychotropic drug and its recreational use among adolescents and young adults represent a serious problem and should be considered by healthcare professionals. Among young people, baclofen poisoning remains relatively infrequent or most likely underestimated and these observations highlight the importance of constructive communication and joining efforts of clinicians and analytical toxicologists.

Self-Diagnosis of Surgical Site Infections: Lessons from a tertiary care centre in Karachi, Pakistan

Background and Objective

Surgical site infections (SSIs) usually manifest post-discharge, rendering accurate diagnosis and treatment challenging, thereby catalyzing the development of alternate strategies like self-monitored SSI surveillance. This study aimed to evaluate the diagnostic accuracy of patients and Infection Control Monitors (ICMs) to develop a replicable method of SSI-detection.

Methods

A two-year prospective diagnostic accuracy study was conducted in Karachi, Pakistan between 2015 and 2017. Patients were educated about SSIs and provided with questionnaires to elicit symptoms of SSI during post-discharge self-screening. Results of patient's self-screening and ICM evaluation at follow-ups were compared to surgeon evaluation.

Results

A total of 348 patients completed the study, among whom 18 (5.5%) developed a SSI. Patient self-screening had a sensitivity of 39%, specificity of 95%, positive predictive value (PPV) of 28%, and negative predictive value (NPV) of 97%. ICM evaluation had a sensitivity of 82%, specificity of 99%, PPV of 82%, and NPV of 99%.

Conclusion

Patients cannot self-diagnose a SSI reliably. However, diagnostic accuracy of ICMs is significantly higher and they may serve as a proxy for surgeons, thereby reducing the burden on specialized surgical workforce in LMICs. Regardless, supplementing post-discharge follow-up with patient self-screening could increase SSI-detection and reduce burden on health systems.

'We are all serving the same Ugandans': A nationwide mixed-methods evaluation of private sector surgical capacity in Uganda

Introduction

Half of all Ugandans (49%) turn to the private or private-not-for-profit (PNFP) sectors when faced with illness, yet little is known about the capacity of these sectors to deliver surgical services. We partnered with the Ministry of Health to conduct a nationwide mixed-methods evaluation of private and PNFP surgical capacity in Uganda.

Methods

A standardized validated facility assessment tool was utilized to assess facility infrastructure, service delivery, workforce, information management, and financing at a randomized nationally representative sample of 16 private and PNFP hospitals. Semi-structured interviews were conducted to qualitatively explore facilitating factors and barriers to surgical, obstetric and anaesthesia (SOA) care. Hospitals walk-throughs and retrospective reviews of operative logbooks were completed.

Results

Hospitals had a median of 177 beds and two operating rooms. Ten hospitals (62.5%) were able to perform all Bellwether procedures (cesarean section, laparotomy and open fracture treatment). Thirty-day surgical volume averaged 102 cases per facility. While most hospitals had electricity, oxygen, running water, and necessary equipment, many reported pervasive shortages of blood, surgical consumables, and anesthetic drugs. Several themes emerged from the qualitative analysis: (1) geographic distance and limited transportation options delay reaching care; (2) workforce shortages impede the delivery of surgical care; (3) emergency and obstetric volume overwhelm the surgical system; (4) medical and non-medical costs delay seeking, reaching, and receiving care; and (5) there is poor coordination of care with insufficient support systems.

Conclusion

As in Uganda’s public sector, barriers to surgery in private and PNFP hospitals in Uganda are cross-cutting and closely tied to resource availability. Critical policy and programmatic developments are essential to build and strengthen Ugandan surgical capacity across all sectors.

Medical Student And Faculty Perceptions Of Undergraduate Surgical Training In The South African And Swedish Tertiary Institutions: A Cross-Sectional Survey

PURPOSE

To evaluate and compare medical student and faculty perceptions of undergraduate surgical training and compare results between South Africa and Sweden.

PATIENTS AND METHODS

An electronic, online questionnaire was anonymously distributed to medical students and surgical faculty at the University of Cape Town (UCT), South Africa, and the Karolinska Institutet (KI), Sweden. The questionnaire explored the perceptions of medical students and surgical faculty regarding the current undergraduate surgical curriculum, as well as existing clinical and theoretical instructional methods.

RESULTS

A total of 120 students (response rate of 24.4%) and 41 faculty (response rate of 74.5%) responded. Students believed they ought to receive significantly more teaching when compared to surgical faculty (p=0.018). Students and faculty generally agreed that students should expect to study approximately six to 20 hrs per week outside of clinical duty. There was general agreement that "small-group tutorials" was the area students learn the most from, whereas students reported "lectures" least helpful. Registrars were reported as the first person students should consult regarding patient care. Fifty-one (42.5%) medical students believed that faculty viewed students as an inconvenience, and 42 (35.0%) students believed that faculty would rather not have students on the clinical team. The majority of faculty (68.3%) reported significantly more negative views on the current undergraduate surgical curriculum when compared to students (p=0.002). UCT faculty reported giving significantly less feedback to students during their surgical rotation when compared to KI faculty (p=0.043).

CONCLUSION

Significant differences exist between surgical faculty and medical student perceptions regarding undergraduate surgical training in developing and developed countries. In order to increase surgical interest among undergraduate medical students, it is imperative for surgical educators to be aware of these differences and find specific strategies to bridge this gap.

"For this one, let me take the risk": why surgical staff continued to perform caesarean sections during the 2014-2016 Ebola epidemic in Sierra Leone

Introduction

Routine health service provision decreased during the 2014–2016 Ebola virus disease (EVD) outbreak in Sierra Leone, while caesarean section (CS) rates at public hospitals did not. It is unknown what made staff provide CS despite the risks of contracting EVD. This study explores Sierra Leonean health worker perspectives of why they continued to provide CS.

Methods

This qualitative study documents the experiences of 15 CS providers who worked during the EVD outbreak. We interviewed surgical and non-surgical CS providers who worked at public hospitals that either increased or decreased CS volumes during the outbreak. Hospitals in all four administrative areas of Sierra Leone were included. Semistructured interviews averaged 97 min and healthcare experience 21 years. Transcripts were analysed by modified framework analysis in the NVivo V.11.4.1 software.

Results

We identified two themes that may explain why providers performed CS despite EVD risks: (1) clinical adaptability and (2) overcoming the moral dilemmas. CS providers reported being overworked and exposed to infection hazards. However, they developed clinical workarounds to the lack of surgical materials, protective equipment and standard operating procedures until the broader international response introduced formal personal protective equipment and infection prevention and control practices. CS providers reported that dutifulness and sense of responsibility for one’s community increased during EVD, which helped them justify taking the risk of being infected. Although most surgical activities were reduced to minimise staff exposure to EVD, staff at public hospitals tended to prioritise performing CS surgery for women with acute obstetric complications.

Conclusion

This study found that CS surgery during EVD in Sierra Leone may be explained by remarkable decisions by individual CS providers at public hospitals. They adapted practically to material limitations exacerbated by the outbreak and overcame the moral dilemmas of performing CS despite the risk of being infected with EVD.

Time-driven activity-based costing of total knee replacements in Karachi, Pakistan

INTRODUCTION

Osteoarthritis of the knee has been identified as the most common disability in Pakistan. Total knee replacement (TKR) surgery is the curative treatment for advanced osteoarthritis of the knee; however, cost remains one of the barriers to effective and timely service delivery.

OBJECTIVE

We conducted a time-driven activity-based costing (TDABC) analysis of TKR to identify major cost drivers and areas for process improvement.

METHODS AND ANALYSIS

We performed a prospective TDABC analysis of patients who underwent bilateral TKR at The Indus Hospital (TIH) during a 14-month period from October 2015 to December 2016. Detailed process maps were developed for each phase of the care cycle. Time durations and costs were allocated to each resource utilised and aggregated across the care cycle, including personnel, direct and indirect costs.

RESULTS

We identified seven care phases for a complete TKR care cycle and created their detailed process maps. Major time contributors were ward stay and discharge (20 160 min), TKR surgery (563 min) and surgical admission (333 min). Overall, 92.10% of time is spent during the ward stay and discharge phase of care. Patients remain hospitalised for an average of 14 days postoperatively. Overall institutional cost of a TKR at TIH was US$4360.51 (Pakistani rupees 456 981.17) per bilateral TKR surgery. The overall primary cost drivers for the full bundle of care were consumables used during TKR surgery itself, consumables utilised in the wards and personnel costs contributing 57.64%, 27.45% and 12.03% of total costs, respectively.

CONCLUSION

Utilising TDABC allowed us to obtain a granular analysis of time and cost that was subsequently used to inform quality process improvement initiatives. In low-resource settings, such as Pakistan, TDABC has the potential to be a useful tool to guide resource allocation and process improvement.

Association Between Gender, Surgery and Mortality for Patients Treated at Médecins Sans Frontières Trauma Centre in Kunduz, Afghanistan

INTRODUCTION

There is paucity of literature describing type of injury and care for females in conflicts. This study aimed to describe the injury pattern and outcome in terms of surgery and mortality for female patients presenting to Médecins Sans Frontières Trauma Centre in Kunduz, Afghanistan, and compare them with males.

MATERIALS AND METHODS

This study retrospectively analysed patient data from 17,916 patients treated at the emergency department in Kunduz between January and September 2015, before its destruction by aerial bombing in October the same year. Routinely collected data on patient characteristics, injury patterns, triage category, time to arrival and outcome were retrieved and analysed. Comparative analyses were conducted using logistic regression.

RESULTS

Females constituted 23.6% of patients. Burns and back injuries were more common among females (1.4% and 3.3%) than among males (0.6% and 2.0%). In contrast, open wounds and thoracic injuries were more common among males (10.1% and 0.6%) than among females (5.2% and 0.2%). Females were less likely to undergo surgery (OR 0.60, CI 0.528-0.688), and this remained significant after adjustment for age, nature of injury, triage category, multiple injuries and delay to arrival (OR 0.80, CI 0.690-0.926). Females also had lower unadjusted odds of mortality (OR 0.49, CI 0.277-0.874), but this was not significant in the adjusted analysis (OR 0.81, CI 0.446-1.453).

CONCLUSION

Our main findings suggest that females seeking care at Kunduz Trauma Centre arrived later, had different injury patterns and were less likely to undergo surgery as compared to males.
