Learning styles vary among general surgery residents: analysis of 12 years of data

PURPOSE: Understanding the learning styles of individuals may assist in the tailoring of an educational program to optimize learning. General surgery faculty and residents have been characterized previously as having a tendency toward particular learning styles. We seek to understand better the learning styles of general surgery residents and differences that may exist within the population. METHODS: The Kolb Learning Style Inventory was administered yearly to general surgery residents at the University of Cincinnati from 1994 to 2006. This tool allows characterization of learning styles into 4 groups: converging, accommodating, assimilating, and diverging. The converging learning style involves education by actively solving problems. The accommodating learning style uses emotion and interpersonal relationships. The assimilating learning style learns by abstract logic. The diverging learning style learns best by observation. Chi-square analysis and analysis of variance were performed to determine significance. RESULTS: Surveys from 1994 to 2006 (91 residents, 325 responses) were analyzed. The prevalent learning style was converging (185, 57%), followed by assimilating (58, 18%), accommodating (44, 14%), and diverging (38, 12%). At the PGY 1 and 2 levels, male and female residents differed in learning style, with the accommodating learning style being relatively more frequent in women and assimilating learning style more frequent in men (Table 1, p < or = 0.001, chi-square test). Interestingly, learning style did not seem to change with advancing PGY level within the program, which suggests that individual learning styles may be constant throughout residency training. If a resident's learning style changed, it tended to be to converging. In addition, no relation exists between learning style and participation in dedicated basic science training or performance on the ABSIT/SBSE. CONCLUSIONS: Our data suggests that learning style differs between male and female general surgery residents but not with PGY level or ABSIT/SBSE performance. A greater understanding of individual learning styles may allow more refinement and tailoring of surgical programs.

Can decision making in general surgery be based on evidence? An empirical study of Cochrane Reviews

BACKGROUND: This empirical study analyzes the current status of Cochrane Reviews (CRs) and their strength of recommendation for evidence-based decision making in the field of general surgery. METHODS: Systematic literature search of the Cochrane Database of Systematic Reviews and the Cochrane Collaboration's homepage to identify available CRs on surgical topics. Quantitative and qualitative characteristics, utilization, and formulated treatment recommendations were evaluated by 2 independent reviewers. Association of review characteristics with treatment recommendation was analyzed using univariate and multivariate logistic regression models. RESULTS: Ninety-three CRs, including 1,403 primary studies and 246,473 patients, were identified. Mean number of included primary studies per CR was 15.1 (standard deviation [SD] 14.5) including 2,650 (SD 3,340) study patients. Two and a half (SD 8.3) nonrandomized trials were included per analyzed CR. Seventy-two (77%) CRs were published or updated in 2005 or later. Explicit treatment recommendations were given in 45 (48%). Presence of a treatment recommendation was associated with the number of included primary studies and the proportion of randomized studies. Utilization of surgical CRs remained low and showed large inter-country differences. The most surgical CRs were accessed in UK, USA, and Australia, followed by several Western and Eastern European countries. CONCLUSION: Only a minority of available CRs address surgical questions and their current usage is low. Instead of unsystematically increasing the number of surgical CRs it would be far more efficient to focus the review process on relevant surgical questions. Prioritization of CRs needs valid methods which should be developed by the scientific surgical community.

Foreskin surgery under local anaesthetic – OK? Or oh no!

Aim: Foreskin surgical procedures such as circumcision, prepuceplasty, frenuloplasty, dorsal slit, reduction of paraphimosis etc. in the adult male is usually performed by both general surgeons and urologists. Our aim was to evaluate the acceptance of performing these procedures in the day procedure unit or in the emergency unit under penile block. 
Method: Fifty patients who underwent foreskin surgeries under local anaesthetic (LA) were evaluated with their experience. Twenty patients who underwent circumcision, 20 patients who underwent foreskin preserving operations such as frenuloplasty or prepuceplasty and 10 patients who underwent other procedures such as reduction of paraphimosis (five) and dorsal slit (five) were included inthe study. The patients were asked about their symptoms such as pain or discomfort during local infiltration of lignocaine, any discomfort during the actual procedure, post-operative discomfort and general acceptance. All the patients were given penile block using smaller size needle (25 gauge, 5/8th inch orange sterile luer slip hypodermic needle) and 1% plain lignocaine. Thirty doctors from general surgery (10), urology (10) and emergency medicine (10) participated in the survey. They were asked about their opinion, confidence and preference about performing foreskin surgical procedures under LA. This included both junior trainees, middle grade doctors and consultants. The majority of middle grade doctors and consultants were fairly confident in performing procedures under LA, whereas the junior trainees in surgery, urology and emergency were lacking confidence. 
Conclusion: Penile block is a safe and effective way ofproviding sufficient anaesthesia for foreskin surgeries. Thetechnique is easy to learn. It reduces post-operative pain aswell. It can reduce the risk and cost of administering generalanaesthesia. doctors who are in training surgical specialityand emergency medicine should be encouraged to learnthe principles and technique in administering penile block.

Desarrollo de un nuevo protocolo de cirugía general, que disminuya las devoluciones de medicamentos e insumos al almacén de cirugía del Hospital Méderi

Esta tesis surge como una oportunidad de mejora en el almacén de cirugías del Hospital MÉDERI, debido a la recurrente devolución de medicamentos e insumos solicitados por las auxiliares de enfermería para las cirugías generales, lo cual repercute directamente en pérdidas de productividad laboral por los re-procesos, un aumento en los errores humanos y posibles pérdidas de medicamentos e insumos. Tras esta clara oportunidad de mejora, se toma la decisión de evaluar el proceso interno del almacén de cirugías con el fin de conocer el punto crítico que genera esta situación; dando como resultado los protocolos de cirugías, los cuales al haber sido diseñados varios años atrás basados en una demanda presentada en ese momento, no están acorde con la realidad que se vive actualmente el almacén de cirugía. Por lo tanto se decidió implementar un pronóstico de promedio móvil, para identificar la demanda real que se presentan en el Hospital MÉDERI, esto seguido de una identificación gráfica comparativa que permitiera definir el nuevo protocolo de cirugía general, lo cual permite disminuir la cantidad de material solicitado, con lo cual se generan disminuciones significativas en el inventario, perdidas y un aumento en la productividad.

Análisis de la calidad en la atención del paciente de cirugía general de urgencia

Objetivo: proponer un instrumento para el seguimiento de la calidad de la atención de pacientes con patologías quirúrgicas abdominales urgentes. Métodos: se revisaron restropectivamente historias clínicas de pacientes quienes requirieron cirugía general de urgencia (CGU) en agosto de 2013. Se analizaron variables demográficas, factores de riesgo, severidad y desenlace hasta el día 30 postoperatorio. Se incluyeron los indicadores de calidad del National Surgical Quality Improvement Program (NSQIP) y el National Trauma Data Bank, y se adicionaron otros. Resultados: Se intervinieron 231 pacientes de 261 procedimientos de CGU. La edad promedio fue 49 años. Los procedimientos más comunes fueron la colecistectomía laparoscópica (37.2%), la apendicectomía (35.6%), la laparotomía exploratoria (12.6%), el drenaje de colección abdominal (9.1%) y la liberación de adherencias (6.9%). La mortalidad fue de 3.46% (n=8), la morbilidad severa fue de 8.04%. La duración de la hospitalización fue de 6.54 días +/- 5.180 y la de hospitalización en Unidad de Cuidado Intensivo fue de 5.7 días +/- 4.42. La oportunidad de salas de cirugía para la apendicetomía fue de 5 horas para las apendicitis con peritonitis generalizada, y de 8 horas para las apendicitis localizadas, 37 horas para colecistitis, 7.48 horas para colangitis y 2.42 horas para diverticulitis. Conclusiones: Crear de un instrumento para la medición de la calidad de la atención de los pacientes en CGU, es necesario para la autoevaluación institucional y para definir planes de mejoramiento y distribución de los recursos.
