Comunicaci贸n asertiva y convivencia escolar en una instituci贸n educativa p煤blica de Ca帽ete, Lima, 2023
El presente trabajo de investigaci贸n se plante贸 como objetivo general determinar la
relaci贸n entre la comunicaci贸n asertiva y convivencia escolar, en la Instituci贸n
Educativa P煤blica de Ca帽ete, Lima, 2023. Este estudio se bas贸 en el enfoque
cuantitativo, de tipo b谩sico, estudio sistem谩tico, d茅 nivel correlacional, con un
dise帽o no experimental, de corte trasversal, ya que se aplic贸 en un solo tiempo,
cuya recolecci贸n de la informaci贸n se fundament贸 en la t茅cnica de la encuesta.
Como instrumento de recolecci贸n de informaci贸n se utiliz贸 un cuestionario para la
variable comunicaci贸n asertiva y otro para la variable convivencia escolar, ambos
con 20 铆tems, en la escala Likert. La poblaci贸n estuvo conformada por 110
estudiantes de la Instituci贸n Educativa P煤blica, de Ca帽ete; la muestra fue de 86
estudiantes de tercero y cuarto grado de secundaria y el muestreo us贸 la t茅cnica
no probabil铆stica. Los resultados de los 铆tems de las encuestas demostraron que
hay evidencias significativas como para concluir que existe relaci贸n significativa
entre la comunicaci贸n asertiva y convivencia escolar, en la Instituci贸n Educativa
P煤blica de Ca帽ete, Lima, 2023, y esa correlaci贸n es positiva considerable, puesto
que el coeficiente de correlaci贸n de Rho Spearman result贸 0,661 con una
significancia de 0.000 < 0.05
Development of a prediction model for postoperative pneumonia A multicentre prospective observational study
BACKGROUND Postoperative pneumonia is associated with increased morbidity, mortality and costs. Prediction models of pneumonia that are currently available are based on retrospectively collected data and administrative coding systems. OBJECTIVE To identify independent variables associated with the occurrence of postoperative pneumonia. DESIGN A prospective observational study of a multicentre cohort (Prospective Evaluation of a RIsk Score for postoperative pulmonary COmPlications in Europe database). SETTING Sixty-three hospitals in Europe. PATIENTS Patients undergoing surgery under general and/or regional anaesthesia during a 7-day recruitment period. MAIN OUTCOME MEASURE The primary outcome was postoperative pneumonia. Definition: the need for treatment with antibiotics for a respiratory infection and at least one of the following criteria: new or changed sputum; new or changed lung opacities on a clinically indicated chest radiograph; temperature more than 38.3 degrees C; leucocyte count more than 12 000 mu l(-1). RESULTS Postoperative pneumonia occurred in 120 out of 5094 patients (2.4%). Eighty-two of the 120 (68.3%) patients with pneumonia required ICU admission, compared with 399 of the 4974 (8.0%) without pneumonia (P < 0.001). We identified five variables independently associated with postoperative pneumonia: functional status [odds ratio (OR) 2.28, 95% confidence interval (CI) 1.58 to 3.12], pre-operative SpO(2) values while breathing room air (OR 0.83, 95% CI 0.78 to 0.84), intra-operative colloid administration (OR 2.97, 95% CI 1.94 to 3.99), intra-operative blood transfusion (OR 2.19, 95% CI 1.41 to 4.71) and surgical site (open upper abdominal surgery OR 3.98, 95% CI 2.19 to 7.59). The model had good discrimination (c-statistic 0.89) and calibration (Hosmer-Lemeshow P = 0.572). CONCLUSION We identified five variables independently associated with postoperative pneumonia. The model performed well and after external validation may be used for risk stratification and management of patients at risk of postoperative pneumonia
