Economic variations in patterns of care and outcomes of patients receiving invasive mechanical ventilation in China: a national cross-sectional survey.

ABSTRACT: Background:Ventilation practice may be affected by economic variations, which might result in different outcomes to mechanically ventilated patients. We aimed to investigate the important effect of economic variations in patients with mechanical ventilation (MV) in China. Methods:We carried out a national prospective multicentre cross-sectional observational study over 1 month of all patients receiving invasive MV for more than 24 hours in 20 intensive care units (ICUs), including patient characteristics, practice of MV, weaning modalities and outcomes, including probability of weaning and survival. Based on the 2012 World Bank classification of counties, patients were divided into high-income and middle-income groups according to gross domestic product per capita in their province of origin. Results:Of the 483 patients enrolled, 291 (60.2%) were from high-income provinces and 192 (39.8%) were from middle-income provinces. Tidal volume, peak pressure, plateau and driving pressure were significantly lower, and the proportion of patients receiving protective ventilation (71.1% vs. 59.9%, P=0.014) was significantly higher in the high-income group than in the middle-income group. The probability of weaning within 28 days was significantly greater in the high-income group than in the middle-income group (P=0.046). Patients in the high-income group had significantly higher median numbers of ventilator-free days within 14 and 28 days than those in the middle-income group (P<0.05). Although the patients did not differ in terms of their demographics, survival within 28 days was significantly higher in the high-income group than in the middle-income group (P=0.025). Driving pressure, positive end-expiratory pressure and spontaneous breathing trial were independently associated with hospital mortality. Conclusions:Important economic differences exist in the management of MV and patient outcomes. Higher income is associated with a higher proportion of protective ventilation, lower driving pressure, shorter weaning and better survival in mechanically ventilated patients in China.

Project description:BackgroundHome mechanical ventilation is an established treatment for chronic respiratory failure resulting in improved survival and quality of life. Technological advancement, evolving health care reimbursement systems and newly implemented national guidelines result in increased utilization worldwide. Prevalence shows great geographical variations and data on East-Central European practice has been scarce to date. The aim of the current study was to evaluate prevalence and characteristics of home mechanical ventilation in Hungary.MethodsWe conducted a nationwide study using an online survey focusing on patients receiving ventilatory support at home. The survey focused on characterization of the site (affiliation, type), experience with home mechanical ventilation, number of patients treated, indication for home mechanical ventilation (disease type), description of home mechanical ventilation (invasive/noninvasive, ventilation hours, duration of ventilation) and description of the care provided (type of follow up visits, hospitalization need, reimbursement).ResultsOur survey uncovered a total of 384 patients amounting to a prevalence of 3.9/100,000 in Hungary. 10.4% of patients received invasive, while 89.6% received noninvasive ventilation. The most frequent diagnosis was central hypopnea syndromes (60%), while pulmonary (20%), neuromuscular (11%) and chest wall disorders (7%) were less frequent indications. Daily ventilation need was less than 8?h in 74.2%, between 8 and 16?h in 15.4% and more than 16?h in 10.4% of patients reported. When comparing sites with a limited (<?50 patients) versus substantial (>?50 patients) case number, we found the former had significantly higher ratio of neuromuscular conditions, were more likely to ventilate invasively, with more than 16?h/day ventilation need and were more likely to provide home visits and readmit patients (p <?0,001).ConclusionsOur results show a reasonable current estimate and characterization of home mechanical ventilation practice in Hungary. Although a growing practice can be assumed, current prevalence is still markedly reduced compared to international data reported, the duality of current data hinting to a possible gap in diagnosis and care for more dependent patients. This points to the importance of establishing home mechanical ventilation centers, where increased experience will enable state of the art care to more dependent patients as well, increasing overall prevalence.

Project description:BackgroundIn intensive care unit (ICU) patients, diaphragmatic dysfunction (DD) can occur on admission or during the subsequent stay. The respective incidence of these two phenomena has not been previously studied in humans. The study was designed to describe temporal trends in diaphragm function in mechanically ventilated (MV) patients.MethodsAncillary study of a prospective, 6-month, observational cohort study conducted in two ICUs. MV patients were studied within 24 h following intubation (day-1) and every 48-72 h thereafter. Diaphragm function was assessed by twitch tracheal pressure (Ptr,stim) in response to bilateral anterior magnetic phrenic nerve stimulation. Diaphragm dysfunction was defined as Ptr,stim < 11 cmH2O. Patients who received MV for at least 5 days were retained, and the first and the last measures were analysed.ResultsForty-three patients were included. Overall, 79 % of patients developed DD at some point during their ICU stay: 23 (53 %) patients presented DD on initiation of mechanical ventilation, 14 (33 %) of whom had persistent DD, while diaphragm function improved in 9 (21 %). Among the remaining 20 (47 %) patients who did not present DD on initiation of MV, 11 (26 %) developed DD during the ICU stay, while 9 (21 %) did not. Mortality was higher in patients with DD either on initiation of mechanical ventilation or during the subsequent ICU stay than in those who never developed DD (35 vs. 0 %, p = 0.04). Duration of MV was higher in patients with DD on initiation of MV that subsequently persisted than in patients who never exhibited diaphragm dysfunction (18 vs. 5 days, p = 0.04). Factors associated with a change in Ptr,stim were: age [linear coefficient regression (Coeff.) -0.097, standard error (SD) 0.047, p = 0.046], PaO2/FiO2 ratio (Coeff. 0.014, SD 0.006, p = 0.0211) and the proportion of the time under MV with sedation (per 10 %, Coeff. -5.359, SD 2.451, p = 0.035).ConclusionsDD is observed in a large majority of MV patients ≥5 days at some point of their ICU stay. Various patterns of DD are observed, including DD on initiation of mechanical ventilation and ICU-acquired DD. Trial registration clinicaltrials.gov Identifier # NCT00786526.

Project description:ImportanceThe opioid crisis is impacting people across the country and deserves attention to be able to curb the rise in opioid-related deaths.ObjectivesTo evaluate practice patterns in opioid infusion administration and dosing for patients with acute respiratory failure receiving invasive mechanical ventilation.DesignRetrospective cohort study.Setting and participantsPatients from 21 hospitals in Kaiser Permanente Northern California and 96 hospitals in Philips electronic ICU Research Institute.Main outcomes and measuresWe assessed whether patients received opioid infusion and the dose of said opioid infusion.ResultsWe identified patients with a diagnosis of acute respiratory failure who were initiated on invasive mechanical ventilation. From each patient, we determined if opioid infusions were administered and, among those who received an opioid infusion, the median daily dose of fentanyl infusion. We used hierarchical regression models to quantify variation in opioid infusion use and the median daily dose of fentanyl equivalents across hospitals. We included 13,140 patients in the KPNC cohort and 52,033 patients in the eRI cohort. A total of 7,023 (53.4%) and 16,311 (31.1%) patients received an opioid infusion in the first 21 days of mechanical ventilation in the KPNC and eRI cohorts, respectively. After accounting for patient- and hospital-level fixed effects, the hospital that a patient was admitted to explained 7% (95% CI, 3-11%) and 39% (95% CI, 28-49%) of the variation in opioid infusion use in the KPNC and eRI cohorts, respectively. Among patients who received an opioid infusion, the median daily fentanyl equivalent dose was 692 µg (interquartile range [IQR], 129-1341 µg) in the KPNC cohort and 200 µg (IQR, 0-1050 µg) in the eRI cohort. Hospital explained 4% (95% CI, 1-7%) and 20% (95% CI, 15-26%) of the variation in median daily fentanyl equivalent dose in the KPNC and eRI cohorts, respectively.Conclusions and relevanceIn the context of efforts to limit healthcare-associated opioid exposure, our findings highlight the considerable opioid exposure that accompanies mechanical ventilation and suggest potential under and over-treatment with analgesia. Our results facilitate benchmarking of hospitals' analgesia practices against risk-adjusted averages and can be used to inform usual care control arms of analgesia and sedation clinical trials.
