Helmet NPPV is feasible and can be used to treat chronic obstructive pulmonary disease patients with acute exacerbation, but it does not improve carbon dioxide elimination as efficiently as does FM NPPV.
Background Surgery is the main modality of cure for solid cancers and was prioritised to continue during COVID-19 outbreaks. This study aimed to identify immediate areas for system strengthening by comparing the delivery of elective cancer surgery during the COVID-19 pandemic in periods of lockdown versus light restriction. Methods This international, prospective, cohort study enrolled 20 006 adult (≥18 years) patients from 466 hospitals in 61 countries with 15 cancer types, who had a decision for curative surgery during the COVID-19 pandemic and were followed up until the point of surgery or cessation of follow-up (Aug 31, 2020). Average national Oxford COVID-19 Stringency Index scores were calculated to define the government response to COVID-19 for each patient for the period they awaited surgery, and classified into light restrictions (index <20), moderate lockdowns (20–60), and full lockdowns (>60). The primary outcome was the non-operation rate (defined as the proportion of patients who did not undergo planned surgery). Cox proportional-hazards regression models were used to explore the associations between lockdowns and non-operation. Intervals from diagnosis to surgery were compared across COVID-19 government response index groups. This study was registered at ClinicalTrials.gov , NCT04384926 . Findings Of eligible patients awaiting surgery, 2003 (10·0%) of 20 006 did not receive surgery after a median follow-up of 23 weeks (IQR 16–30), all of whom had a COVID-19-related reason given for non-operation. Light restrictions were associated with a 0·6% non-operation rate (26 of 4521), moderate lockdowns with a 5·5% rate (201 of 3646; adjusted hazard ratio [HR] 0·81, 95% CI 0·77–0·84; p<0·0001), and full lockdowns with a 15·0% rate (1775 of 11 827; HR 0·51, 0·50–0·53; p<0·0001). In sensitivity analyses, including adjustment for SARS-CoV-2 case notification rates, moderate lockdowns (HR 0·84, 95% CI 0·80–0·88; p<0·001), and full lockdowns (0·57, 0·54–0·60; p<0·001), remained independently associated with non-operation. Surgery beyond 12 weeks from diagnosis in patients without neoadjuvant therapy increased during lockdowns (374 [9·1%] of 4521 in light restrictions, 317 [10·4%] of 3646 in moderate lockdowns, 2001 [23·8%] of 11 827 in full lockdowns), although there were no differences in resectability rates observed with longer delays. Interpretation Cancer surgery systems worldwide were fragile to lockdowns, with one in seven patients who were in regions with full lockdowns not undergoing planned surgery and experiencing longer preoperative delays. Although short-term oncological outcomes were not compromised in those selected for surgery, delays and non-operations might lead to long-term reductions in survival. During current and future periods of societal restriction, the resilience of elective surgery systems requires strengthening, which might include...
Background: Acute respiratory failure (ARF) occurring during idiopathic pulmonary fibrosis (IPF) is associated with a poor prognosis. In this subset of individuals, mechanical ventilation (MV) may be required. Objectives: We analysed the characteristics of a group of IPF patients undergoing MV for ARF in order to give some indications on the supposed prognosis. Methods: Hospital records of 34 consecutive patients with IPF, who underwent MV for ARF, were retrospectively examined. Demographic data, time from diagnosis, gas exchange, Acute Physiology and Chronic Health Evaluation (APACHE) II score, ARF causes and MV failure were recorded. Results: Fifteen subjects (group A) underwent invasive MV and 19 patients (group B) non-invasive ventilation (NIV). The 2 groups were different for disease severity (APACHE II score 24.2 ± 6 vs. 19.5 ± 5.9; p = 0.01). Both ventilatory strategies temporarily increased PaO2/FiO2 as compared with spontaneous breathing (group A: 148.5 ± 52 vs. 99 ± 39, p = 0.0004; group B: 134 ± 36 vs. 89 ± 26, p = 0.0004). NIV reduced the respiratory rate (26 ± 7 vs. 36 ± 9 with spontaneous breathing; p = 0.002). Duration of MV correlated with the time of evolution of IPF (r = 0.45; p = 0.018). The in-hospital mortality rate was 85% (100% for invasive MV, 74% for NIV). Four of the 5 survivors died within 6 months from hospital discharge (range 2–6 months). Conclusions: MV does not appear to have a significant impact on the survival of patients with end-stage IPF. NIV may be useful for compassionate use, providing relief from dyspnoea and avoiding aggressive approaches.
ObjectiveAnticoagulation reversal, intensive blood pressure lowering, neurosurgery, and access to critical care might all be beneficial in acute intracerebral hemorrhage (ICH). We combined and implemented these as the “ABC” hyperacute care bundle and sought to determine whether the implementation was associated with lower case fatality.MethodsThe ABC bundle was implemented from June 1, 2015 to May 31, 2016. Key process targets were set, and a registry captured consecutive patients. We compared 30‐day case fatality before, during, and after bundle implementation with multivariate logistic regression and used mediation analysis to determine which care process measures mediated any association. Difference‐in‐difference analysis compared 30‐day case fatality with 32,295 patients with ICH from 214 other hospitals in England and Wales using Sentinel Stroke National Audit Programme data.ResultsA total of 973 ICH patients were admitted in the study period. Compared to before implementation, the adjusted odds of death by 30 days were lower in the implementation period (odds ratio [OR] = 0.62, 95% confidence interval [CI] = 0.38–0.97, p = 0.03), and this was sustained after implementation (OR = 0.40, 95% CI = 0.24–0.61, p < 0.0001). Implementation of the bundle was associated with a 10.8 percentage point (95% CI = −17.9 to −3.7, p = 0.003) reduction in 30‐day case fatality in difference‐in‐difference analysis. The total effect of the care bundle was mediated by a reduction in do‐not‐resuscitate orders within 24 hours (52.8%) and increased admission to critical care (11.1%).InterpretationImplementation of the ABC care bundle was significantly associated with lower 30‐day case fatality after ICH.
