Risk factors for reintubation and mortality among patients who had unplanned extubation.

BACKGROUND: Unplanned extubation (UE) occurs among 2%-16% of patients with mechanical ventilation (MV). Failed UE requiring reintubation could be associated with several adverse events. AIMS: The aim of this study was to investigate the outcomes and prognostic factors of patients with UE in intensive care units (ICUs). METHODS: We prospectively registered the patients who had UE and retrospectively reviewed the electronic medical records for 96-bed ICUs between 1 January 2009, and 31 December 2020. RESULTS: A total of 392 patients had UE, and 234 patients (59.7%) were ≥65 years (older adult group). The median Acute Physiology and Chronic Health Evaluation (APACHE) II score were 17 and the median Glasgow Coma Scale score was 10. In total, 205 patients (52.3%) were reintubated within 48 h (due to failed UE) and 75 patients (19.1%) died during hospitalization. Multivariate analyses were performed to evaluate those factors predicting failed UE and mortality. These analyses demonstrated that higher positive end-expiratory pressure (PEEP) and the admission APACHE II scores predicted failed UE. A higher fraction of inspiration O2 (FiO2 ) and minute ventilation; lower haemoglobin (Hb); and higher instances of liver cirrhosis, cancer, and failed UE were independently associated with hospital mortality. CONCLUSION: We concluded that among patients who had UE, higher FiO2 or minute ventilation, or under MV or with lower Hb, liver cirrhosis, cancer, and failed UE tended to have higher mortality. RELEVANCE TO CLINICAL PRACTICE: Patients with high disease severity indices who have an increased risk of UE required special attention to techniques to prevent endotracheal tubes from accidental removal.

Outcome of improved care bundle in acute respiratory failure patients.

BACKGROUND: Prolonged physical immobilization has negative effects on patients on mechanical ventilation (MV). AIMS: To introduce a quality improvement programme with early mobilization on the outcomes of patients on MV in the intensive care unit (ICU). We particularly studied the impact of the ABCDE (daily Awakening, Breathing trial, drug Co-ordination, Delirium survey and treatment, and Early mobilization) bundle on the outcome of MV patients with acute respiratory failure in the ICU. DESIGN: This is a retrospective, observational, before-and-after outcome study. METHOD: Adult patients on MV (N = 173) admitted to a medical centre ICU with 19 beds in southern Taiwan were enrolled. A multidisciplinary team (critical care nurse, nursing assistant, respiratory therapist, physical therapist, patient's family) performed ABCDE with early mobilization within 72 hours of MV when patients became haemodynamically stable (twice daily [30 minutes each time], 5 days/week during family visits and in co-operation with family members). MAIN OUTCOME MEASURES: The main outcome measures were differences of MV duration, ICU and hospital length of stay, medical costs, and intra-hospital mortality before (phase 1) and after (phase 2) bundle care. RESULTS: Phases 1 and 2 revealed several differences, including Acute Physiology and Chronic Health Evaluation (APACHE) II and blood urea nitrogen and creatinine levels. The patients in phase 2 had a significantly lower mean ICU length of stay (8.0 vs 12.0 days) but a similar MV duration (170.2 vs 188.1 hours), hospital stays (21.1 vs 23.3 days) with reduced costs (22.1 vs 31.7 × 104 NT$), and intra-hospital mortality (8.3 vs. 36.6%). CONCLUSIONS: The ABCDE care bundle improved the outcome of acute renal failure patients with MV, especially shortening ICU stays and lowering medical costs and hospital mortality. RELEVANCE TO CLINICAL PRACTICE: An ABCDE care bundle with an inter-professional, evidence-based, multicomponent ICU early mobilization management strategy can reduce ICU stays, hospital expenditure, and mortality among acute respiratory failure patients with MV.

Effectiveness of early rehabilitation on patients with chronic obstructive lung disease and acute respiratory failure in intensive care units: A case-control study.

The effect of early rehabilitation on the outcome of patients with chronic obstructive pulmonary disease (COPD) and acute respiratory failure (ARF) in intensive care units (ICUs) remains unclear. We examined the effect of early rehabilitation on the outcomes of COPD patients requiring mechanical ventilation (MV) in the ICU. This retrospective, observational, case-control study was conducted in a medical center with a 19-bed ICU. The records of all 105 ICU patients with COPD and ARF who required MV from January to December 2011 were examined. The outcomes (MV duration, rates of successful weaning and survival, lengths of ICU and hospital stays, and medical costs) were recorded and analyzed. During the study period, 35 patients with COPD underwent early rehabilitation in the ICU and 70 demographically and clinically matched patients with similar COPD stage, cause of intubation, type of respiratory failure, and levels of disease severity who had not undergone early rehabilitation in the ICU were selected as comparative controls. Multiple regression analysis showed that early rehabilitation was significantly negatively associated with MV duration. Early rehabilitation for COPD patients in the ICU with ARF shortened the duration of their MV.

Clinical efficacy of acupuncture for pain relief from renal colic: A meta-analysis and trial sequence analysis.

Background: This meta-analysis aimed at investigating the efficacy of acupuncture for relieving renal colic and reducing the risk of analgesic-related complications. Methods: Randomized controlled trials (RCTs) comparing the efficacy of acupuncture (acupuncture group) with conventional interventions (control group) were screened from MEDLINE, EMBASE, Cochrane library databases, China Knowledge Network (CNKI), and Airiti Library till July 15, 2022. The primary outcome was the rate of effective pain relief (response rate), while secondary outcomes included the time of onset of pain relief, visual analog scale (VAS) at 30-60 min and risk of side effects. Results: Thirteen eligible studies involving 1,212 participants published between 1992 and 2021 were analyzed. Compared with the control group, patients receiving acupuncture had a higher overall response rate [risk ratio (RR) = 1.12, 95% CI: 1.05-1.19, p = 0.0002, I 2 = 41%, 1,136 patients] (primary outcome) and a faster pain relief [MD = -10.74 min, 95% CI: -12.65 to -8.82, p < 0.00001, I 2 = 87%, 839 patients]. Patients receiving acupuncture had a lower pain score [MD = -0.65, 95% CI: -1.09 to -0.21, p = 0.21, I 2 = 55%, 327 patients] and risk of side effects (RR = 0.11, 95% CI: 0.04-0.26, p < 0.00001, I 2 = 0, 314 patients) compared to those receiving conventional interventions. Results from trial sequence analysis revealed sufficient evidence supporting the beneficial effects of acupuncture on response rate, time to pain relief, and pain score at 30-60 min. Conclusion: Compared with conventional analgesic-based interventions, acupuncture can more efficiently relieve renal colic with fewer adverse effects. The limited number and quality of included studies warrant more clinical RCTs to support our findings.

The prognosis in extremely elderly patients receiving orotracheal intubation and mechanical ventilation after planned extubation.

The main objective of this study was to evaluate the outcomes of extremely elderly patients receiving orotracheal intubation and mechanical ventilation after planned extubation. This retrospective cohort study included extremely elderly patients (>90 years) who received mechanical ventilation and passed planned extubation. We reviewed all intensive care unit patients in a medical center between January 1, 2010, and December 31, 2017. There were 19,518 patients (aged between 20 and 105 years) during the study period. After application of the exclusion criteria, there were 213 patients who underwent planned extubation: 166 patients survived, and 47 patients died. Compared with the mortality group, the survival group had lower Acute Physiology and Chronic Health Evaluation II scores and higher Glasgow Coma Scale (GCS) scores, with scores of 19.7 ±â€Š6.5 (mean ±â€Šstandard deviation) vs 22.2 ±â€Š6.0 (P = .015) and 9.5 ±â€Š3.5 vs 8.0 ±â€Š3.0 (P = .007), respectively. The laboratory data revealed no significant difference between the survival and mortality groups except for blood urea nitrogen (BUN) and hemoglobin. After multivariate logistic regression analysis, a lower GCS, a higher BUN level, weaning beginning 3 days after intubation and reintubation during hospitalization were associated with poor prognosis. In this cohort of extremely elderly patients undergoing planned extubation, a lower GCS, a higher BUN level, weaning beginning 3 days after intubation and reintubation during hospitalization were associated with mortality.

The effect of early cardiopulmonary rehabilitation on the outcomes of intensive care unit survivors.

This study aims to compare the impact of early and late post-discharge cardiopulmonary rehabilitation on the outcomes of intensive care unit (ICU) survivors.The retrospective, cohort study used a sub-database of the Taiwan National Health Insurance Research Database (NHIRD) that contained information of all patients had ICU admission between 2000 and 2012. Early group was defined if patients had received cardiopulmonary rehabilitation within 30 days after ICU discharge, and late group was define as if patients had received cardiopulmonary rehabilitation between 30 days and 1 year after ICU discharge. The end points were mortality and re-admission during the 3-year follow-up.Among 2136 patients received cardiopulmonary rehabilitation after ICU discharge, 994 was classified early group and other 1142 patients were classified as late group. Overall, early group had a lower mortality rate (6.64% vs. 10.86%, P = .0006), and a lower ICU readmission rate (47.8% vs. 57.97%, P < 0.0001) than late group after 3-year follow-up. Kaplan-Meier analysis showed that early group had significantly lower mortality (P = .0009) and readmission rate (P < .0001) than late group. In multivariate analysis, the risk of ICU readmission was found to be independently associated with late group (hazard ratio, [HR], 1.28; 95% confidence intervals, [CI], 1.13-1.47).Early post-discharge cardiopulmonary rehabilitation among ICU survivors has the long-term survival benefit and significantly decreases the readmission rate.

Predicting weaning difficulty for planned extubation patients with an artificial neural network.

This study aims to construct a neural network to predict weaning difficulty among planned extubation patients in intensive care units.This observational cohort study was conducted in eight adult ICUs in a medical center about adult patients experiencing planned extubation.The data of 3602 patients with planned extubation in ICUs of Chi-Mei Medical Center (from Dec. 2009 through Dec. 2011) was used to train and test an artificial neural network (ANN) model. The input features contain 47 clinical risk factors and the outputs are classified into three categories: simple, difficult, and prolonged weaning. A deep ANN model with four hidden layers of 30 neurons each was developed. The accuracy is 0.769 and the area under receiver operating characteristic curve for simple weaning, prolonged weaning, and difficult weaning are 0.910, 0.849, and 0.942 respectively.The results revealed that the ANN model achieved a good performance in prediction the weaning difficulty in planned extubation patients. Such a model will be helpful for predicting ICU patients' successful planned extubation.

Prognostic factors and outcomes of unplanned extubation.

This study investigated the prognostic factors and outcomes of unplanned extubation (UE) in patients in a medical center's 6 intensive care units (ICUs) and calculated their mortality risk. We retrospectively reviewed the medical records of all adult patients in Chi Mei Medical Center who underwent UE between 2009 and 2015. During the study period, there were 305 episodes of UE in 295 ICU patients (men: 199 [67.5%]; mean age: 65.7 years; age range: 18-94 years). The mean Acute Physiology and Chronic Health Evaluation (APACHE) II score was 16.4, mean therapeutic intervention scoring system (TISS) score was 26.5, and mean Glasgow coma scale score was 10.4. One hundred thirty-six patients (46.1%) were re-intubated within 48 h. Forty-five died (mortality rate: 15.3%). Multivariate analyses showed 5 risk factors-respiratory rate, APACHE II score, uremia, liver cirrhosis, and weaning status-were independently associated with mortality. In conclusion, five risk factors including a high respiratory rate before UE, high APACHE II score, uremia, liver cirrhosis, and not in the process of being weaned-were associated with high mortality in patients who underwent UE.

Establishing failure predictors for the planned extubation of overweight and obese patients.

We investigated failure predictors for the planned extubation of overweight (body mass index [BMI] = 25.0-29.9) and obese (BMI ≥ 30) patients. All patients admitted to the adult intensive care unit (ICU) of a tertiary hospital in Taiwan were identified. They had all undergone endotracheal intubation for > 48 h and were candidates for extubation. During the study, 595 patients (overweight = 458 [77%]); obese = 137 [23%]) with planned extubation after weaning were included in the analysis; extubation failed in 34 patients (5.7%). Their mean BMI was 28.5 ± 3.8. Only BMI and age were significantly different between overweight and obese patients. The mortality rate for ICU patients was 0.8%, and 2.9% for inpatients during days 1-28; the overall in-hospital mortality rate was 8.4%. Failed Extubation group patients were significantly older, had more end-stage renal disease (ESRD), more cardiovascular system-related respiratory failure, higher maximal inspiratory pressure (MIP), lower maximal expiratory pressure (MEP), higher blood urea nitrogen, and higher ICU- and 28-day mortality rates than did the Successful Extubation group. Multivariate logistic regression showed that cardiovascular-related respiratory failure (odds ratio [OR]: 2.60; 95% [confidence interval] CI: 1.16-5.80), ESRD (OR: 14.00; 95% CI: 6.25-31.35), and MIP levels (OR: 0.94; 95% CI: 0.90-0.97) were associated with extubation failure. We conclude that the extubation failure risk in overweight and obese patients was associated with cardiovascular system-related respiratory failure, ESRD, and low MIP levels.
