Bleeding and long-term survival after lung resections: nationwide observational cohort study.

ABSTRACT:

Background

Bleeding following lung surgery can lead to reoperation and blood transfusions, potentially impairing outcomes. This study aimed to assess how bleeding complications affect long-term survival and postoperative complications in a nationwide contemporary group of patients undergoing lung resections.

Methods

Adult patients who underwent lung resections, for both malignant and nonmalignant diagnoses, between 2013-2021, were included from the Swedish national registry for thoracic surgery. Patients with bleeding complications, defined as requiring reexploration and/or transfusions, were compared to patients without bleeding complications regarding long-term survival and postoperative complications. We used propensity scores and optimal full matching to account for differences in baseline characteristics between the groups.

Results

The cohort comprised 15,617 adult patients, of which 646 patients (4.1%) had bleeding complications. The unadjusted 90-day mortality was 9.4% vs. 1.0% in the bleeding group vs. no bleeding group, respectively. After matching, the odds ratio (OR) for 90-day mortality in the bleeding group compared with the no bleeding group was 3.66 [95% confidence interval (CI): 2.17-6.17]. Long term overall survival was lower among patients in the bleeding group, adjusted hazard ratio (95% CI) for all-cause mortality was 1.47 (1.29-1.69). Postoperative complications were more common in the bleeding group (OR: 3.00, 95% CI: 2.38-3.79), including infections (OR: 2.80, 95% CI: 1.86-4.20). Bleeding complications were more frequent during the first third of the study time period as compared to the last third (P<0.001).

Conclusions

Patients with bleeding complications had reduced long-term survival and higher incidence of postoperative complications. A declining trend in bleeding rates over time was noted.

Project description:BackgroundLong-term survival after single-ventricle palliation and the effect of dominant ventricle morphology in large, unselected series of patients are scarcely reported.Methods and resultsThis nationwide cohort study included all children undergoing operation with single-ventricle palliation during their first year of life in Sweden between January 1994 and December 2019. Data were obtained from institutional records and assessment of underlying cardiac anomaly and dominant ventricular morphology was based on complete review of medical records, surgical reports, and echocardiographic examinations. Data on vital status and date of death were retrieved from the Swedish Cause of Death Register, allowing for complete data on survival. Among 766 included patients, 333 patients (43.5%) were classified as having left or biventricular dominance, and 432 patients (56.4%) as having right ventricular (RV) dominance (of whom 231 patients had hypoplastic left heart syndrome). Follow-up was 98.7% complete (10 patients emigrated). Mean follow-up was 11.3 years (maximum, 26.7 years). Long-term survival was significantly higher in patients with left ventricular compared with RV dominance (10-year survival: 91.0% [95% CI, 87.3%-93.6%] versus 71.1% [95% CI, 66.4%-75.2%]). RV dominance had a significant impact on outcomes after first-stage palliation but was also associated with impaired survival after completed total cavopulmonary connection. In total, 34 (4.4%) patients underwent heart transplantation. Of these 34 patients, 25 (73.5%) had predominant RV morphology.ConclusionsThis study provides clinically relevant knowledge about the long-term prognosis in patients with different underlying cardiac anomalies undergoing single-ventricle palliation. RV dominance had a significant impact on outcomes after initial surgical treatment but was also associated with impaired survival after completed Fontan circulation.RegistrationURL: https://www.clinicaltrials.gov; Unique identifier: NCT03356574.

Project description:BackgroundInformation is lacking regarding long-term survival and predictive factors for mortality in patients with acute hypoxemic respiratory failure due to coronavirus disease 2019 (COVID-19) and undergoing invasive mechanical ventilation. We aimed to estimate 180-day mortality of patients with COVID-19 requiring invasive ventilation, and to develop a predictive model for long-term mortality.MethodsRetrospective, multicentre, national cohort study between March 8 and April 30, 2020 in 16 intensive care units (ICU) in Spain. Participants were consecutive adults who received invasive mechanical ventilation for COVID-19. Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection detected in positive testing of a nasopharyngeal sample and confirmed by real time reverse-transcriptase polymerase chain reaction (rt-PCR). The primary outcomes was 180-day survival after hospital admission. Secondary outcomes were length of ICU and hospital stay, and ICU and in-hospital mortality. A predictive model was developed to estimate the probability of 180-day mortality.Results868 patients were included (median age, 64 years [interquartile range [IQR], 56-71 years]; 72% male). Severity at ICU admission, estimated by SAPS3, was 56 points [IQR 50-63]. Prior to intubation, 26% received some type of noninvasive respiratory support. The unadjusted overall 180-day survival rates was 59% (95% CI 56-62%). The predictive factors measured during ICU stay, and associated with 180-day mortality were: age [Odds Ratio [OR] per 1-year increase 1.051, 95% CI 1.033-1.068)), SAPS3 (OR per 1-point increase 1.027, 95% CI 1.011-1.044), diabetes (OR 1.546, 95% CI 1.085-2.204), neutrophils to lymphocytes ratio (OR per 1-unit increase 1.008, 95% CI 1.001-1.016), failed attempt of noninvasive positive pressure ventilation prior to orotracheal intubation (OR 1.878 (95% CI 1.124-3.140), use of selective digestive decontamination strategy during ICU stay (OR 0.590 (95% CI 0.358-0.972) and administration of low dosage of corticosteroids (methylprednisolone 1 mg/kg) (OR 2.042 (95% CI 1.205-3.460).ConclusionThe long-term survival of mechanically ventilated patients with severe COVID-19 reaches more than 50% and may help to provide individualized risk stratification and potential treatments.Trial registrationClinicalTrials.gov Identifier: NCT04379258.
