- Adverse events leading to intensive care unit admission in a low-and-middle-income-country: A prospective cohort study and a systematic review(2024) PEDRO, Rodolpho Augusto de Moura; BESEN, Bruno Adler Maccagnan Pinheiro; MENDES, Pedro Vitale; GOMES, Augusto Cezar Marins; CARVALHO, Marcelo Ticianelli de; MALBOUISSON, Luiz Marcelo Sa; PARK, Marcelo; TANIGUCHI, Leandro UtinoIntroduction: Adverse events (AE) are frequent in critical care and could be even more prevalent in LMIC due to a shortage of ICU beds and Human resources. There is limited data on how relevant AE are among the reasons for ICU admission, being all of which published by High-Income-Countries services. Our main goal is to describe the rate of adverse events-related ICU admissions and their preventability in a LMIC scenario, comparing our results with previous data.Methods: This was a prospective cohort study, during a one-year period, in two general ICUs from a tertiary public academic hospital. Our exposure of interest was ICU admission related to an AE in adult patients, we further characterized their preventability and clinical outcomes. We also performed a systematic review to identify and compare previous published data on ICU admissions due to AE.Results: Among all ICU admissions, 12.1% were related to an AE (9.8% caused by an AE, 2.3% related but not directly caused by an AE). These ICU admissions were not associated with a higher risk of death, but most of them were potentially preventable (70.9% of preventability rate, representing 8.6% of all ICU admissions). The meta-analysis resulted in a proportion of ICU admissions due to AE of 11% (95% CI 6%-16%), with a pre-ventability rate of 54% (95% CI 42%-66%).Conclusions: In this prospective cohort, adverse events were a relevant reason for ICU admission. This result is consistent with data retrieved from non-LMIC as shown in our meta-analysis. The high preventability rate described reinforces that quality and safety programs could work as a tool to optimize scarce resources.

- Comparison between ultrasound- and bronchoscopy-guided percutaneous dilational tracheostomy in critically ill patients: A retrospective cohort study(2015) GOBATTO, Andre Luiz Nunes; BESEN, Bruno Adler Maccagnan Pinheiro; TIERNO, Paulo Fernando Guimaraes Morando Marzocchi; MENDES, Pedro Vitale; CADAMURO, Filipe; JOELSONS, Daniel; MELRO, Livia; PARK, Marcelo; MALBOUISSON, Luiz Marcelo SaIntroduction: Percutaneous dilational tracheostomy (PDT) is routinely performed in the intensive care unit with bronchoscopic guidance. Recently, ultrasound (US) has emerged as a new safety adjunct tool to increase the efficacy of PDT. However, the available data are limited to case series without any control group. Hence, a retrospective cohort study was designed to evaluate the efficacy of US-guided PDT compared with bronchoscopy-guided PDT. Methods: All patients who were submitted to PDT after the standardization of US-guided PDT technique in our institution were analyzed. Demographic and procedure-related variables, complications, and clinical outcomes were collected and compared in patients undergoing US- or bronchoscopy-guided PDT. Results: Sixty patients who had been submitted to PDT were studied, including 11 under bronchoscopy guidance and 49 under US guidance. No surgical conversion was necessary in any of the procedures, and bronchoscopy assistance was only required in 1 case in the US group. The procedure length was shorter in the US group than in the bronchoscopy group (12 vs 15 minutes, P = .028). None of the patients had any major complications. The minor complication rates were not significantly different between the groups, nor was the probability of breathing without assistance within 28 days, intensive care unit length of stay, or hospital mortality. Conclusion: Ultrasound-guided PDT is effective, safe, and associated with similar complication rates and clinical outcomes compared with bronchoscopy-guided PDT.
- Characteristics of critically ill patients with cancer associated with intensivist's perception of inappropriateness of ICU admission: A retrospective cohort study(2024) SILVA, Carla Marchini Dias da; BESEN, Bruno Adler Maccagnan Pinheiro; JR, Antonio Paulo NassarPurpose: Although admitting cancer patients to the ICU is no longer an issue, it may be valuable to identify patients perceived least likely to benefit from admission. Our objective was to investigate factors associated with potentially inappropriate ICU admission. Methods: Retrospective cohort study of patients with cancer with unplanned ICU admission. We classified admissions as appropriate or potentially inappropriate according to Society of Critical Care Medicine guidelines. We used logistic regression model to assess factors associated with inappropriateness for ICU admission.Results: From 3384 patients, 663 (19.6%) were classified as potentially inappropriate. They received more invasive mechanical ventilation (25.3% vs 12.5%, P < 0.001) and vasopressors (34.4% vs 30.1%, P = 0.034), had higher ICU [3 (2,6) vs 2 (1,4), P < 0.001] length-of-stay, higher ICU (32.7% vs 8.4%, P < 0.001), hospital (71.9% vs 21.3%, P < 0.001), and one-year mortality (97.6% vs 54.7%, P < 0.001) compared with those considered appropriate. Performance status impairment, more severe organ dysfunctions at admission, metastatic disease, and source of ICU admission were the characteristics associated with intensivist's perception of inappropriateness of ICU admission.Conclusions: These findings may help guide ICU admission policies and triage criteria for end-of-life discussions among hospitalized patients with cancer.
