[Analysis of incident reports in an anesthesiology unit of a university hospital]. / De la anestesia a la seguridad de la atención: experiencia de 6 años en el análisis de reportes de incidentes en un hospital universitario.

BACKGROUND: Incident reporting is an effective strategy used to enhance patient safety. An incident is an event that could eventually result in harm to a patient. AIM: To classify and analyze incidents reported by an Anesthesiology division at a University hospital in Chile. MATERIAL AND METHODS: A retrospective analysis of the reported incidents registered in our institutional database from January 2008 to January 2014. They were classified according to three variables proposed by the World Health Organization system to determine the type of incident and patients’ potential harm. RESULTS: There were 297 reports registered. Etiologic classification according to the WHO system showed that 29% (n = 85) were related with management, 20% (59) with drugs, 20% (59) with medical devices, 16% (48) with procedures and 15% (46) with human factors. Seventy two percent (58) of incidents caused low or moderate harm and 28% (22) resulted in a severe adverse event or death. CONCLUSIONS: Our analysis highlights that a high rate of incidents are associated with management, the leading cause of reports in our center. Due to the low incident report rate in our country, it is difficult to perform appropriate comparisons with other centers. In the future, local incident reporting systems should be improved.

World Health Organization (WHO) surgical safety checklist implementation and its impact on perioperative morbidity and mortality in an academic medical center in Chile.

Health care organizations are unsafe. Numerous centers have incorporated the WHO Surgical Safety Checklist in their processes with good results; however, only limited information is available about its effectiveness in Latin America. We aimed to evaluate the impact of the checklist implementation on the in-hospital morbidity and mortality rate in a tertiary health care center. After Institutional review board approval, and using data from our hospital administrative records, we conducted a retrospective analysis of all surgical encounters (n = 70,639) over the period from January 2005 to December 2012. Propensity scoring (PS) methods (matching and inverse weighting) were used to compare the pre and postintervention period, after controlling for selection bias. After PS matching (n = 29,250 matched pairs), the in-hospital mortality rate was 0.82% [95% confidence interval (CI), 0.73-0.92] before and 0.65% (95% CI, 0.57-0.74) after checklist implementation [odds ratio (OR) 0.73; 95% CI, 0.61-0.89]. The median length of stay was 3 days [interquartile range (IQR), 1-5] and 2 days (IQR, 1-4) for the pre and postchecklist period, respectively (P < 0.01).This is the first Latin American study reporting a decrease in mortality after the implementation of the WHO Surgical Checklist in adult surgical patients. This is a strong and simple tool to make health care safer, especially in developing countries.

Prueba de esfuerzo graduada y coronariografía / Graded exercise test and coronary angiography

La prueba de esfuerzo graduada es un procedimiento útil para pesquisar o reafirmar la sospecha clínica de enfermedad coronaria. Esto ocurre principalmente en hombres, en los que existe una correlación estrecha entre la frecuencia de las alteraciones y la magnitud de la afección coronaria. En las mujeres, por razones que aún se desconocen (existen varias hipótesis que tratan de explicarlo), la correlación entre prueba de esfuerzo graduada y cineangiocoronariografía no es buena
