Objective: To investigate the applicability of the Respiratory Rate-Oxygenation Index to identify the risk of high-flow nasal cannula failure in post-extubation pneumonia patients.
Methods: This was a 2-year retrospective observational study conducted in a reference hospital in Bogotá, Colombia. All patients in whom post-extubation high-flow nasal cannula therapy was used as a bridge to extubation were included in the study. The Respiratory Rate-Oxygenation Index was calculated to assess the risk of post-extubation high-flow nasal cannula failure.
Results: A total of 162 patients were included in the study. Of these, 23.5% developed high-flow nasal cannula failure. The Respiratory Rate-Oxygenation Index was significantly lower in patients who had high-flow nasal cannula failure [median (IQR): 10.0 (7.7 - 14.4) versus 12.6 (10.1 - 15.6); p = 0.006]. Respiratory Rate-Oxygenation Index > 4.88 showed a crude OR of 0.23 (95%CI 0.17 - 0.30) and an adjusted OR of 0.89 (95%CI 0.81 - 0.98) stratified by severity and comorbidity. After logistic regression analysis, the Respiratory Rate-Oxygenation Index had an adjusted OR of 0.90 (95%CI 0.82 - 0.98; p = 0.026). The area under the Receiver Operating Characteristic curve for extubation failure was 0.64 (95%CI 0.53 - 0.75; p = 0.06). The Respiratory Rate-Oxygenation Index did not show differences between patients who survived and those who died during the intensive care unit stay.
Conclusion: The Respiratory Rate-Oxygenation Index is an accessible tool to identify patients at risk of failing high-flow nasal cannula post-extubation treatment. Prospective studies are needed to broaden the utility in this scenario.
Objective: To analyze the association of patient safety culture perceived by nursing professionals with incidents recorded during nursing shifts in intensive care units.
Methods: This was a cross-sectional study that investigated patient safety culture measured by the Hospital Survey on Patient Safety Culture instrument. Descriptive statistics, chi-square tests, Student's t-test and multiple linear regression models were analyzed considering a significance level of 5%.
Results: The study reported a mean of 3.1 (standard deviation of 0.4) for the culture of patient safety in the perception of nursing professionals and 480 incidents with and without damage recorded during the nursing shifts. The variables patient safety culture with a difference between means of 0.543 (95%CI 0.022 - 1.065; p < 0.05) and nursing assistants with a difference between means of -0.133 (95%CI -0.192 - -0.074; p < 0.05) were associated with the incidents recorded during the nursing shifts. Further, nursing assistants had a lower tendency to record incidents than did the nurses.
Conclusion: The strengthening of the patient safety culture and the aspects tangential to the nursing professionals represent a possible target for interventions to encourage the recording of incidents during the nursing shift shifts and improve patient safety.
