ABSTRACT
Background: Various predictive models have been published to identify outpatients with inadequate colonic cleansing who may benefit from intensified preparations to improve colonoscopy quality. The main objective of this study was to compare the accuracy of three predictive models for identifying poor bowel preparation in outpatients undergoing colonoscopy. Methods: This cross-sectional study included patients scheduled for outpatient colonoscopy over a 3-month period. We evaluated and compared three predictive models (Models 1-3). The quality of colonic cleansing was assessed using the Boston Bowel Preparation Scale. We calculated the area under the curve (AUC) and the corresponding 95% confidence interval for each model. Additionally, we performed simple and multiple logistic regression analyses to identify variables associated with inadequate colonic cleansing and developed a new model. Results: A total of 649 consecutive patients were included in the study, of whom 84.3% had adequate colonic cleansing quality. The AUCs of Model 1 (AUC = 0.67, 95% CI [0.63-0.70]) and Model 2 (AUC = 0.62, 95% CI [0.58-0.66]) were significantly higher than that of Model 3 (AUC = 0.54, 95% CI [0.50-0.58]; p < 0.001). Moreover, Model 1 outperformed Model 2 (p = 0.013). However, the new model did not demonstrate improved accuracy compared to the older models (AUC = 0.671). Conclusions: Among the three compared models, Model 1 showed the highest accuracy for predicting poor bowel preparation in outpatients undergoing colonoscopy and could be useful in clinical practice to decrease the percentage of inadequately prepared patients.
ABSTRACT
Se realizó un estudio descriptivo transversal, determinándose por medio de encuestas el nivel de conocimientos sobre los factores de riesgo sexuales más frecuentes para adquirir VIH/SIDA; datos generales sobre el VIH; comportamientos sexuales y factores de riesgo de los adultos jóvenes. El universo estuvo conformado por 404 estudiantes de noveno, décimo y undécimo grados del casco urbano del municipio Arauquita, Arauca, Colombia. Se efectuó un muestreo sistemático aleatorio y se tomó como muestra 50 por ciento del universo, 202 estudiantes. Se aplicó una encuesta cuestionario estructurado de carácter anónima de 30 preguntas de selección múltiple y exclusión abierta numérica(AU)

A cross-sectional descriptive study was made based on surveys which determined the level of knowledge on the most frequent risk factors to catch HIV/AIDS; general data about HIV; sex behaviors and risk factors for young adults. The universe of study was made up of 404 students at 9th, 10th and 11th grades, who live in the urban area of Arauquita municipality, Arauca, Colombia. A randomized systematic sampling was carried out; 50 % of the students were taken as a sample, that is, 202 students. The survey used was an anonymous structured questionnaire consisting of 30 multiple choice questions and open numerical exclusion.
