RESUMEN

ABSTRACT Purpose: To develop and validate a new test of specific technical skills required for microsurgical varicocelectomy. Materials and Methods: An electronic questionnaire was sent to 558 members of the Brazilian Society of Urology for the validation of the task-specific checklist (TSC) for assessment of microsurgical varicocelectomy. Participants who had experience in this procedure were selected as judges. For construct validation, 12 participants including attending urologists and urological residents in training were recruited for voluntary participation. We formed a group of three experts and a group of nine novices, who had to perform the steps of microsurgical varicocelectomy on a simulation model using human placenta. Each participant was filmed and two blinded raters would then evaluate their performance using the TSC of microsurgical varicocelectomy. Results: 14 judges were recruited. The assessment tool was reformulated, according to the judges suggestions and had the content validity achieved. The final version of the TSC was comprised of the task-specific score, a series of 4 items scored in a binary fashion designed for microscopic sub-inguinal varicocelectomy. The differences between the performance of participants with different levels of experience reflected the construct validity. The reliability between the raters was high. The mean time required to complete the training of microsurgical varicocelectomy in simulation model was significantly shorter for experts compared to novices (201 vs. 496 seconds, p=0.01). Conclusions: This preliminary study suggests that the task-specific checklist of microsurgical varicocelectomy is reliable and valid in assessing microsurgical skills.

RESUMEN

BACKGROUND: The aim of this study was to perform a cross-cultural adaptation of the Objective Structured Assessment of Technical Skill (OSATS) tool into Brazilian Portuguese and to determine its reproducibility and validity in Brasil. METHODS: A Brazilian Portuguese version of OSATS was created through a process of translation, back-translation, expert panel evaluation, pilot testing, and then its validation. For the construct and the concurrent validities, twelve participants were divided into a group of six experts and six novices, who had to perform tasks on a simulation model using human placentas. Each participant was filmed, and two blinded raters would then evaluate their performance using the traditional subjective method and then the Brazilian Portuguese version of OSATS. RESULTS: The Brazilian Portuguese version of OSATS had the face, content, construct, and concurrent validities achieved. The average experts' score and standard deviations were 34 and 0.894, respectively, for Judge 1 and 34.33 and 0.816 for Judge 2. In the case of novices, it was 13.33 and 2.388 for Judge 1 and 13.33 and 3.204 for Judge 2. The concordance between the judges was evident, with the Correlation Coefficient (Pearson) of 0.9944 with CI 95% between 0.9797 and 0.9985, with p < 10-10, evidencing the excellent reproducibility of the instrument. CONCLUSION: This preliminary study suggests that the Brazilian Portuguese version of OSATS can reliably and validly assess surgical skills in Brasil.

RESUMEN

The present study aimed to analyze factors associated with access of dental care services by Brazilian hemodialysis patients. A cross-sectional study was carried out with 467 hemodialysis patients aging from 19 to 90 years in two renal therapy centers located in the cities of Contagem and Belo Horizonte, Southeastern Brazil. Data were collected through an oral clinical examination of the patients and the application of a structured questionnaire. The dependent variable was the access to dental care, measured by the question "Have you consulted with a dentist in last six months?". The mean age of participants was 49.9 years. The average number of teeth present in the mouth was 19.3. An average of 1.5 teeth with dental caries cavities lesion was diagnosed among hemodialysis patients. One-third of the sample had gone to the dentist in the last six months (27.8%). The access to dental care was associated with formal education (OR = 1.5 [1.1-2.4]), professional advising to consult with a dentist (OR = 2.1 [1.2-3.8]) and prevalence of dental caries (OR = 2.1 [1.3-3.2]). Hemodialysis patients with eight or more years of formal education, who received professional advising to consult with a dentist and without dental caries cavities had higher chances obtaining access to dental care.

Resumo Este estudo objetivou analisar os fatores associados ao uso de serviços odontológicos por pacientes em hemodiálise. Foi realizado um estudo transversal com 467 pacientes em hemodiálise, na faixa etária de 19 a 90 anos, de Contagem e Belo Horizonte, região Sudeste do Brasil. Os dados foram coletados por meio de exame clínico bucal dos participantes e da aplicação de um questionário estruturado. A variável dependente foi o acesso odontológico, mensurado pela pergunta "Você foi ao dentista nos últimos seis meses?". A média de idade dos participantes foi de 49,9 anos. A média de dentes presentes na boca foi de 19,3. Uma média de 1,5 dentes com lesão de cárie cavitada foi diagnosticada entre os pacientes em hemodiálise. Um terço da amostra afirmou ter ido ao dentista nos últimos seis meses (27,8%). O acesso odontológico dos pacientes em hemodiálise foi associado à escolaridade (OR = 1,5 [1,1-2,4]), orientação profissional para ir ao dentista (OR = 2,1 [1,2-3,8]) e prevalência de cárie dentária (OR = 2,1 [1,3-3,2]). Os pacientes em hemodiálise com oito anos ou mais de escolaridade, que receberam orientação profissional para ir ao dentista e sem cárie dentária apresentaram maior chance de terem acesso odontológico.

RESUMEN

BACKGROUND: Brain tumors are complex 3-dimensional lesions. Their resection involves training and the use of the multiple microsurgical techniques available for removal. Simulation models, with haptic and visual realism, may be useful for improving the bimanual technical skills of neurosurgical residents and neurosurgeons, potentially decreasing surgical errors and thus improving patient outcomes. OBJECTIVE: To describe and assess an ex vivo placental model for brain tumor microsurgery using a simulation tool in neurosurgical psychomotor teaching and assessment. METHODS: Sixteen human placentas were used in this research project. Intravascular blood remnants were removed by continuous saline solution irrigation of the 2 placental arteries and placental vein. Brain tumors were simulated using silicone injections in the placental stroma. Eight neurosurgeons and 8 neurosurgical residents carried out the resection of simulated tumors using the same surgical instruments and bimanual microsurgical techniques used to perform human brain tumor operations. Face and content validity was assessed using a subjective evaluation based on a 5-point Likert scale. Construct validity was assessed by analyzing the surgical performance of the neurosurgeon and resident groups. RESULTS: The placenta model simulated brain tumor surgical procedures with high fidelity. Results showed face and content validity. Construct validity was demonstrated by statistically different surgical performances among the evaluated groups. CONCLUSION: Human placentas are useful haptic models to simulate brain tumor microsurgical removal. Results using this model demonstrate face, content, and construct validity.
