RESUMO

DESCRIPTION: The American College of Physicians (ACP) developed this guideline to provide clinical recommendations on the appropriate use of high-flow nasal oxygen (HFNO) in hospitalized patients for initial or postextubation management of acute respiratory failure. It is based on the best available evidence on the benefits and harms of HFNO, taken in the context of costs and patient values and preferences. METHODS: The ACP Clinical Guidelines Committee based these recommendations on a systematic review on the efficacy and safety of HFNO. The patient-centered health outcomes evaluated included all-cause mortality, hospital length of stay, 30-day hospital readmissions, hospital-acquired pneumonia, days of intubation or reintubation, intensive care unit (ICU) admission and ICU transfers, patient comfort, dyspnea, delirium, barotrauma, compromised nutrition, gastric dysfunction, functional independence at discharge, discharge disposition, and skin breakdown. This guideline was developed using the GRADE (Grading of Recommendations Assessment, Development and Evaluation) method. TARGET AUDIENCE AND PATIENT POPULATION: The target audience is all clinicians, and the target patient population is adult patients with acute respiratory failure treated in a hospital setting (including emergency departments, hospital wards, intermediate or step-down units, and ICUs). RECOMMENDATION 1A: ACP suggests that clinicians use high-flow nasal oxygen rather than noninvasive ventilation in hospitalized adults for the management of acute hypoxemic respiratory failure (conditional recommendation; low-certainty evidence). RECOMMENDATION 1B: ACP suggests that clinicians use high-flow nasal oxygen rather than conventional oxygen therapy for hospitalized adults with postextubation acute hypoxemic respiratory failure (conditional recommendation; low-certainty evidence).

RESUMO

The objective of this analysis was to evaluate and report on the economic impact of implementing an integrated, quality, and operational improvement program on chronic obstructive pulmonary disease (COPD) care from acute through post-acute care settings. This initiative was established in a cohort of 12 hospitals in Alabama and sought to address COPD readmission through improved workflows pertaining to early diagnosis, efficient care transitions, and patient visibility across the entire care episode. Implementation of the initiative was influenced by lean principles, particularly cross-functional agreement of workflows to improve COPD care delivery and outcomes. A budget impact model was developed to calculate cost savings directly from objective data collected during this initiative. The model estimated payer annual savings over 5 years. Patients were classified for analysis based on whether or not they received noninvasive ventilation. Scenario analyses calculated savings for payers covering different COPD cohort sizes. The base case revealed annual per patient savings of $11,263 for patients treated through the quality improvement program versus traditional care. The model projected cumulative savings of $52 million over a 5-year period. Clinical incorporation of non-invasive ventilation (NIV) resulted in $20,535 annual savings per patient and projected $91 million over 5 years. We conclude that an integrated management program for COPD patients across the care continuum is associated with substantial cost savings and significantly reduced hospital readmissions.

RESUMO

INTRODUCTION: Chronic non-invasive ventilation (NIV) has become evidence-based care for stable hypercapnic COPD patients. While the number of patients increases, home initiation of NIV would greatly alleviate the healthcare burden. We hypothesise that home initiation of NIV with the use of telemedicine in stable hypercapnic COPD is non-inferior to in-hospital NIV initiation. METHODS: Sixty-seven stable hypercapnic COPD patients were randomised to initiation of NIV in the hospital or at home using telemedicine. Primary outcome was daytime arterial carbon dioxide pressure (PaCO2) reduction after 6 months NIV, with a non-inferiority margin of 0.4 kPa. Secondary outcomes were health-related quality of life (HRQoL) and costs. RESULTS: Home NIV initiation was non-inferior to in-hospital initiation (adjusted mean difference in PaCO2 change home vs in-hospital: 0.04 kPa (95% CI -0.31 to 0.38 kPa), with both groups showing a PaCO2 reduction at 6 months compared with baseline (home: from 7.3±0.9 to 6.4±0.8 kPa (p<0.001) and in-hospital: from 7.4±1.0 to 6.4±0.6 kPa (p<0.001)). In both groups, HRQoL improved without a difference in change between groups (Clinical COPD Questionnaire total score-adjusted mean difference 0.0 (95% CI -0.4 to 0.5)). Furthermore, home NIV initiation was significantly cheaper (home: median €3768 (IQR €3546-€4163) vs in-hospital: median €8537 (IQR €7540-€9175); p<0.001). DISCUSSION: This is the first study showing that home initiation of chronic NIV in stable hypercapnic COPD patients, with the use of telemedicine, is non-inferior to in-hospital initiation, safe and reduces costs by over 50%. TRIAL REGISTRATION NUMBER: NCT02652559.

RESUMO

OBJECTIVES: To describe the frequency of non-invasive ventilation (NIV) and endotracheal intubation use in neonates diagnosed with respiratory distress syndrome (RDS); to describe resources utilization (length of stay (LOS), charges, costs) among NIV and intubated RDS groups. STUDY DESIGN: Retrospective study from the national Kid's Inpatient Database of the Healthcare Cost and Utilization Project, for the years 1997-2012. Propensity scoring and multivariate regression analysis used to describe differences. RESULTS: A total of 595,254 out of 42,912,090 cases were identified with RDS. There was an increase in NIV use from 6% in 1997 to 17% in 2012. After matching, patients receiving NIV only were associated with shorter LOS: (95%CI) 25 (25.3,25.7) vs. 35 (34.2,34.9) days, decreased costs: ($/1k) 46.1 (45.5,46.8) vs. 65.0 (64.1,66.0), decreased charges: 130.3 (128.6,132.1) vs. 192.1 (189.5,194.6) compared to intubated neonates. CONCLUSION: There was a three-fold increase in NIV use within the 15-year study period. NIV use was associated with decreased LOS, charges and costs compared to intubated patients.

RESUMO

OBJECTIVE: To determine amyotrophic lateral sclerosis (ALS)-associated costs incurred by patients covered by Medicare and/or commercial insurance before, during and after diagnosis and provide cost details. METHODS: Costs were calculated from the Medicare Standard Analytical File 5% sample claims data from Parts A and B from 2009, 2010 and 2011 for ALS Medicare patients aged ≥70 years (monthly costs) and ≥65 years (costs associated with disability milestones). Commercial insurance patients aged 18-63 years were selected based on the data provided in the Coordination of Benefits field from Truven MarketScan® in 2008-2010. RESULTS: Monthly costs increased nine months before diagnosis, peaked during the index month (Medicare: $10,398; commercial: $9354) and decreased but remained high post-index. Costs generally shifted from outpatient to inpatient and private nursing after diagnosis; prescriptions and durable medical equipment costs were much higher for commercial patients post-diagnosis. Patients appeared to progress to disability milestones more rapidly as their disease progressed in severity (14.4 months to non-invasive ventilation [NIV] vs. 16.6 months to hospice), and their costs increased accordingly (NIV: $58,973 vs. hospice: $76,179). CONCLUSIONS: For newly diagnosed ALS patients in the U.S., medical costs are substantial and increase rapidly and substantially with each disability milestone.

RESUMO

OBJECTIVE: To estimate the cost-effectiveness of Nasal High Flow (NHF) in the intensive care unit (ICU) compared with standard oxygen or non-invasive ventilation (NIV) from a UK NHS perspective. METHODS: Three cost-effectiveness models were developed to reflect scenarios of NHF use: first-line therapy (pre-intubation model); post-extubation in low-risk, and high-risk patients. All models used randomized control trial data on the incidence of intubation/re-intubation, events leading to intubation/re-intubation, mortality and complications. NHS reference costs were primarily used. Sensitivity analyses were conducted. RESULTS: When used as first-line therapy, Optiflow™ NHF gives an estimated cost-saving of £469 per patient compared with standard oxygen and £611 versus NIV. NHF cost-savings for high severity sub-group were £727 versus standard oxygen, and £1,011 versus NIV. For low-risk post-intubation patients, NHF generates estimated cost-saving of £156 versus standard oxygen. NHF decreases the number of re-intubations required in these scenarios. Results were robust in most sensitivity analyses. For high-risk post-intubation patients, NHF cost-savings were £104 versus NIV. NHF results in a non-significant increase in re-intubations required. However, reduction in respiratory failure offsets this. CONCLUSIONS: For patients in ICU who are at risk of intubation or re-intubation, NHF cannula is likely to be cost-saving.

RESUMO

Nasal high flow is a promising novel oxygen delivery device, whose mechanisms of action offer some beneficial effects over conventional oxygen systems. The administration of a high flow of heated and humidified gas mixture promotes higher and more stable inspiratory oxygen fraction values, decreases anatomical dead space and generates a positive airway pressure that can reduce the work of breathing and enhance patient comfort and tolerance. Nasal high flow has been used as a prophylactic tool or as a treatment device mostly in patients with acute hypoxaemic respiratory failure, with the majority of studies showing positive results. Recently, its clinical indications have been expanded to post-extubated patients in intensive care or following surgery, for pre- and peri-oxygenation during intubation, during bronchoscopy, in immunocompromised patients and in patients with "do not intubate" status. In the present review, we differentiate studies that suggest an advantage (benefit) from other studies that do not suggest an advantage (no benefit) compared to conventional oxygen devices or noninvasive ventilation, and propose an algorithm in cases of nasal high flow application in patients with acute hypoxaemic respiratory failure of almost any cause.

RESUMO

BACKGROUND: Although evidence suggests significant clinical benefits of home noninvasive ventilation (NIV) for management of severe chronic obstructive pulmonary disease (COPD), economic analyses supporting the use of this technology are lacking. OBJECTIVES: To evaluate the economic impact of adopting home NIV, as part of a multifaceted intervention program, for severe COPD. METHODS: An economic model was developed to calculate savings associated with the use of Advanced NIV (averaged volume assured pressure support with autoexpiratory positive airway pressure; Trilogy100, Philips Respironics, Inc., Murrysville, PA) versus either no NIV or a respiratory assist device with bilevel pressure capacity in patients with severe COPD from two distinct perspectives: the hospital and the payer. The model examined hospital savings over 90 days and payer savings over 3 years. The number of patients with severe COPD eligible for home Advanced NIV was user-defined. Clinical and cost data were obtained from a quality improvement program and published reports. Scenario analyses calculated savings for hospitals and payers covering different COPD patient cohort sizes. RESULTS: The hospital base case (250 patients) revealed cumulative savings of $402,981 and $449,101 over 30 and 90 days, respectively, for Advanced NIV versus both comparators. For the payer base case (100,000 patients), 3-year cumulative savings with Advanced NIV were $326 million versus no NIV and $1.04 billion versus respiratory assist device. CONCLUSIONS: This model concluded that adoption of home Advanced NIV with averaged volume assured pressure support with autoexpiratory positive airway pressure, as part of a multifaceted intervention program, presents an opportunity for hospitals to reduce COPD readmission-related costs and for payers to reduce costs associated with managing patients with severe COPD on the basis of reduced admissions.

RESUMO

BACKGROUND: People with chronic obstructive pulmonary disease (COPD) sometimes experience anxiety, depression and comorbid cognitive deficits. Rather than being merely a consequence of symptom-related physical impairments these additional problems may be part of the clinical course of the condition. The relationship between the physical and psychological aspects of the condition is illustrated by the patterns of use of non-invasive ventilation (NIV); NIV is often rejected or used inappropriately, resulting in clinical deterioration and an increase in health care costs. The study aims to analyse the effects of psychological support on the acceptance of, and adherence to, NIV. The primary outcome will be a latent variable related to indices of use of NIV equipment and adherence to treatment regime; while survival rates and psychological variables will constitute the secondary outcomes. METHODS: A two-arm randomised controlled trial will be conducted. We aim to recruit 150 COPD patients for whom NIV is indicated. The experimental group will receive a brief course of psychological support that will include counselling, relaxation and mindfulness-based exercises. In some cases, it will also include neuropsychological rehabilitation exercises. Support will be delivered via four to eight meetings at the HD Respiratory Rehabilitation Unit, at home or via telemedicine. Controls will receive standard care and watch educational videos related to the management of their disease. DISCUSSION: This investigation will gain insight about the role of a psychological intervention as part of a treatment plan during the process of adaptation to NIV in COPD patients.

RESUMO

OBJECTIVE: Despite increasing use, evidence is mixed as to the appropriate use of noninvasive ventilation in patients with pneumonia. We aimed to determine the relationship between receipt of noninvasive ventilation and outcomes for patients with pneumonia in a real-world setting. DESIGN, SETTING, PATIENTS: We performed a retrospective cohort study of Medicare beneficiaries (aged > 64 yr) admitted to 2,757 acute-care hospitals in the United States with pneumonia, who received mechanical ventilation from 2010 to 2011. EXPOSURES: Noninvasive ventilation versus invasive mechanical ventilation. MEASUREMENT AND MAIN RESULTS: The primary outcome was 30-day mortality with Medicare reimbursement as a secondary outcome. To account for unmeasured confounding associated with noninvasive ventilation use, an instrumental variable was used-the differential distance to a high noninvasive ventilation use hospital. All models were adjusted for patient and hospital characteristics to account for measured differences between groups. Among 65,747 Medicare beneficiaries with pneumonia who required mechanical ventilation, 12,480 (19%) received noninvasive ventilation. Patients receiving noninvasive ventilation were more likely to be older, male, white, rural-dwelling, have fewer comorbidities, and were less likely to be acutely ill as measured by organ failures. Results of the instrumental variable analysis suggested that, among marginal patients, receipt of noninvasive ventilation was not significantly associated with differences in 30-day mortality when compared with invasive mechanical ventilation (54% vs 55%; p = 0.92; 95% CI of absolute difference, -13.8 to 12.4) but was associated with significantly lower Medicare spending ($18,433 vs $27,051; p = 0.02). CONCLUSIONS: Among Medicare beneficiaries hospitalized with pneumonia who received mechanical ventilation, noninvasive ventilation use was not associated with a real-world mortality benefit. Given the wide CIs, however, substantial harm associated with noninvasive ventilation could not be excluded. The use of noninvasive ventilation for patients with pneumonia should be cautioned, but targeted enrollment of marginal patients with pneumonia could enrich future randomized trials.

RESUMO

BACKGROUND: Chronic obstructive pulmonary disease (COPD) is a chronic progressive lung disease characterised by non-reversible airflow obstruction. Exacerbations are a key cause of morbidity and mortality and place a considerable burden on health-care systems. While there is evidence that patients benefit from non-invasive ventilation (NIV) in hospital during an acute exacerbation, evidence supporting home use for more stable COPD patients is limited. In the U.K., domiciliary NIV is considered on health economic grounds in patients after three hospital admissions for acute hypercapnic respiratory failure. OBJECTIVE: To assess the clinical effectiveness and cost-effectiveness of domiciliary NIV by systematic review and economic evaluation. DATA SOURCES: Bibliographic databases, conference proceedings and ongoing trial registries up to September 2014. METHODS: Standard systematic review methods were used for identifying relevant clinical effectiveness and cost-effectiveness studies assessing NIV compared with usual care or comparing different types of NIV. Risk of bias was assessed using Cochrane guidelines and relevant economic checklists. Results for primary effectiveness outcomes (mortality, hospitalisations, exacerbations and quality of life) were presented, where possible, in forest plots. A speculative Markov decision model was developed to compare the cost-effectiveness of domiciliary NIV with usual care from a UK perspective for post-hospital and more stable populations separately. RESULTS: Thirty-one controlled effectiveness studies were identified, which report a variety of outcomes. For stable patients, a modest volume of evidence found no benefit from domiciliary NIV for survival and some non-significant beneficial trends for hospitalisations and quality of life. For post-hospital patients, no benefit from NIV could be shown in terms of survival (from randomised controlled trials) and findings for hospital admissions were inconsistent and based on limited evidence. No conclusions could be drawn regarding potential benefit from different types of NIV. No cost-effectiveness studies of domiciliary NIV were identified. Economic modelling suggested that NIV may be cost-effective in a stable population at a threshold of £30,000 per quality-adjusted life-year (QALY) gained (incremental cost-effectiveness ratio £28,162), but this is associated with uncertainty. In the case of the post-hospital population, results for three separate base cases ranged from usual care dominating to NIV being cost-effective, with an incremental cost-effectiveness ratio of less than £10,000 per QALY gained. All estimates were sensitive to effectiveness estimates, length of benefit from NIV (currently unknown) and some costs. Modelling suggested that reductions in the rate of hospital admissions per patient per year of 24% and 15% in the stable and post-hospital populations, respectively, are required for NIV to be cost-effective. LIMITATIONS: Evidence on key clinical outcomes remains limited, particularly quality-of-life and long-term (> 2 years) effects. Economic modelling should be viewed as speculative because of uncertainty around effect estimates, baseline risks, length of benefit of NIV and limited quality-of-life/utility data. CONCLUSIONS: The cost-effectiveness of domiciliary NIV remains uncertain and the findings in this report are sensitive to emergent data. Further evidence is required to identify patients most likely to benefit from domiciliary NIV and to establish optimum time points for starting NIV and equipment settings. FUTURE WORK RECOMMENDATIONS: The results from this report will need to be re-examined in the light of any new trial results, particularly in terms of reducing the uncertainty in the economic model. Any new randomised controlled trials should consider including a sham non-invasive ventilation arm and/or a higher- and lower-pressure arm. Individual participant data analyses may help to determine whether or not there are any patient characteristics or equipment settings that are predictive of a benefit of NIV and to establish optimum time points for starting (and potentially discounting) NIV.

RESUMO

BACKGROUND: Non-invasive ventilation (NIV), in the form of continuous positive airway pressure (CPAP) or bilevel inspiratory positive airway pressure (BiPAP), is used in hospital to treat patients with acute respiratory failure. Pre-hospital NIV may be more effective than in-hospital NIV but requires additional ambulance service resources. OBJECTIVES: We aimed to determine the clinical effectiveness and cost-effectiveness of pre-hospital NIV compared with usual care for adults presenting to the emergency services with acute respiratory failure and to identify priorities for future research. DATA SOURCES: Fourteen electronic databases and research registers (including MEDLINE In-Process & Other Non-Indexed Citations, MEDLINE, EMBASE, and Cumulative Index to Nursing and Allied Health Literature) were searched from inception to August 2013, supplemented by hand-searching reference lists and contacting experts in the field. REVIEW METHODS: We included all randomised or quasi-randomised controlled trials of pre-hospital NIV in patients with acute respiratory failure. Methodological quality was assessed according to established criteria. An aggregate data network meta-analysis (NMA) of mortality and intubation was used to jointly estimate intervention effects relative to usual care. A NMA, using individual patient-level data (IPD) and aggregate data where IPD were not available, was carried out to assess whether or not covariates were treatment effect modifiers. A de novo economic model was developed to explore the costs and health outcomes when pre-hospital NIV (specifically CPAP provided by paramedics) and standard care (in-hospital NIV) were applied to a hypothetical cohort of patients with acute respiratory failure. RESULTS: The literature searches identified 2284 citations. Of the 10 studies that met the inclusion criteria, eight were randomised controlled trials and two were quasi-randomised trials (six CPAP; four BiPAP; sample sizes 23-207 participants). IPD were available from seven trials (650 patients). The aggregate data NMA suggested that CPAP was the most effective treatment in terms of mortality (probability = 0.989) and intubation rate (probability = 0.639), and reduced both mortality [odds ratio (OR) 0.41, 95% credible interval (CrI) 0.20 to 0.77] and intubation rate (OR 0.32, 95% CrI 0.17 to 0.62) compared with standard care. The effect of BiPAP on mortality (OR 1.94, 95% CrI 0.65 to 6.14) and intubation rate (OR 0.40, 95% CrI 0.14 to 1.16) compared with standard care was uncertain. The combined IPD and aggregate data NMA suggested that sex was a statistically significant treatment effect modifier for mortality. The economic analysis showed that pre-hospital CPAP was more effective and more expensive than standard care, with an incremental cost-effectiveness ratio of £20,514 per quality-adjusted life-year (QALY) and a 49.5% probability of being cost-effective at the £20,000-per-QALY threshold. Variation in the incidence of eligible patients had a marked impact on cost-effectiveness and the expected value of sample information for a future randomised trial. LIMITATIONS: The meta-analysis lacked power to detect potentially important differences in outcome (particularly for BiPAP), the intervention was not always compared with the best alternative care (in-hospital NIV) in the primary studies and findings may not be generalisable. CONCLUSIONS: Pre-hospital CPAP can reduce mortality and intubation rates, but cost-effectiveness is uncertain and the value of further randomised evaluation depends on the incidence of suitable patients. A feasibility study is required to determine if a large pragmatic trial of clinical effectiveness and cost-effectiveness is appropriate.

RESUMO

INTRODUCTION: Obesity is an escalating issue, with an accompanying increase in referrals of patients with obesity-related respiratory failure. Currently, these patients are electively admitted to hospital for initiation of non-invasive ventilation (NIV), but it is unknown whether outpatient initiation is as effective as inpatient set-up. We hypothesise that outpatient set-up using an autotitrating NIV device will be more cost-effective than a nurse-led inpatient titration and set-up. METHODS AND ANALYSIS: We will undertake a multinational, multicentre randomised controlled trial. Participants will be randomised to receive the usual inpatient set-up, which will include nurse-led initiation of NIV or outpatient set-up with an automated NIV device. They will be stratified according to the trial site, gender and previous use of NIV or continuous positive airway pressure. Assuming a 10% dropout rate, a total sample of 82 patients will be required. Cost-effectiveness will be evaluated using standard treatment costs and health service utilisation as well as health-related quality of life measures (severe respiratory insufficiency (SRI) and EuroQol-5 dimensions (EQ-5D)).

RESUMO

BACKGROUND: Continuous tracheostomy mechanical ventilation users with Duchenne muscular dystrophy are institutionalized or have home nursing services (licensed practical nurse/registered nurse), whereas patients dependent on continuous noninvasive ventilatory support (CNVS) can avoid hospitalizations and publically paid services. DESIGN AND OBJECTIVE: This is a retrospective analysis comparing cost and physician effort for managing CNVS and continuous tracheostomy mechanical ventilation users with Duchenne muscular dystrophy. RESULTS: Compared with ongoing personal care, physician services and intercurrent hospitalization costs were negligible. Ten home continuous tracheostomy mechanical ventilation users had 16.4 hrs per day of licensed practical nurse/registered nurse care costing $269,370 per year; 14 were institutionalized at $237,350 per year; and 8 were decannulated to CNVS, with 5 subsequently returning home, costing only $9,800 per year for respiratory equipment. For 93 CNVS users, costs ranged from $9,800 per year for 37 without publically funded assistance, $44,968 per year for 3 with nurses' aides, $81,395 per year for 35 with unskilled personal assistance services, and $239,805 per year for 12 with licensed practical nurses/registered nurses. Twenty-eight became CNVS dependent without hospitalization or evaluation for home care. CONCLUSIONS: Noninvasive management permits cost-effective living at home but is disincentivized by fixed hospital diagnosis-related groups compensation that encourages rapid tracheotomy as well as expensive institutionalization and nursing care.

RESUMO

BACKGROUND: Newborn infants with respiratory failure are often treated with intubation and mechanical ventilation for prolonged periods of time. Our objective was to evaluate whether increasing use of non-invasive respiratory support in newborn infants can improve patient health and reduce costs. METHODS: We utilized a natural experiment that took place in October 2008 when a large neonatal intensive care unit in Norway moved into a new hospital building with new medical equipment. A change in respiratory support towards increasing use of nasal biphasic positive airway pressure (n-BiPAP) instead of invasive mechanical ventilation treatment followed the acquisition of the new equipment. We used a difference-in-difference method and data from the Norwegian National Patient Registry to assess morbidity, mortality, number of hospital days and hospital costs in our unit following this change. We stratified the results according to gestational age groups. RESULTS: We found a reduction in morbidity including bronchopulmonary dysplasia, retinopathy of prematurity and intraventricular hemorrhage. No change in mortality was found. We found a reduction in number of hospital days and hospital costs for preterm infants with gestational age <28 weeks and for term infants with diagnoses affecting respiration. CONCLUSIONS: We conclude that increasing use of n-BiPAP may improve health and reduce costs. However, more research is needed to establish best practice. Comparing hospitals where treatment practices change to hospitals where the same change does not occur may be a useful way to evaluate the efficacy of such a change, especially when hospitals can be studied over time.

RESUMO

There has been an exponential increase in the use of home noninvasive ventilation (NIV). Despite growing use, there is a paucity of evidence-based guidelines and practice standards in the United States to assist clinicians in the initiation and ongoing management of home NIV. Consequently, home NIV practices are being influenced by complicated local reimbursement policies and coding. This article aims to provide a practice management perspective for clinicians providing home NIV, including Local Coverage Determination reimbursement criteria for respiratory assist devices, Durable Medical Equipment coding, and Current Procedural Terminology coding to optimize clinical care and minimize lost revenue. It highlights the need for further research and development of evidence-based clinical practice standards to ensure best practice policies are in place for this rapidly evolving patient population.

RESUMO

BACKGROUND: Home mechanical ventilation is usually initiated in hospital. However, cost-effectiveness of inpatient set up has never been compared to outpatient adaptation in a randomized design. A Prospective, multicenter, non-inferiority trial was conducted comparing the effectiveness of adaptation to noninvasive mechanical ventilation (NIMV) performed in the ambulatory or hospital setting in patients with chronic respiratory failure secondary to restrictive thoracic disease, obesity-hypoventilation syndrome or neuromuscular disease. METHODS: The study included 53 candidates for NIMV, randomized to ambulatory adaptation (AA) (n = 27) or hospital adaptation (HA) (n = 26). The patients' characteristics were recorded before establishing ventilation and at 1 and 6 months after. The main outcome variable was PaCO2 decrease at 6 months following initiation of NIMV. The direct costs of the two interventions were compared. RESULTS: Before starting NIMV, PaCO2 was 50.4 ± 6.8 mmHg in the AA group and 50.3 ± 5.7 mmHg in the HA group. At 6 months of NIMV use, a significant improvement in PaCO2 relative to baseline was found in both groups: mean (95% CI) PaCO2 decrease was 4.9 (2.3; 7.4) mmHg in AA and 3.3 (1.4; 5.1) mmHg in HA. The direct calculated cost was 1500 euros per patient in AA and 2692 euros per patient in HA. CONCLUSIONS: Adaptation to NIMV in the ambulatory setting is not inferior to hospital adaptation in terms of therapeutic equivalence in stable patients with chronic respiratory failure secondary to restrictive thoracic disease, obesity-hypoventilation syndrome or neuromuscular disease. Outpatient adaptation may represent a cost saving for the healthcare system. CLINICAL TRIAL: Identifier number NCT00698958 at www.clinicaltrials.gov.
