Is the Rehabilitation Complexity Scale useful in individuals undergoing in-hospital pulmonary rehabilitation?

OBJECTIVE: To assess validity and responsiveness of the Extended Rehabilitation Complexity Scale (RCS-Ev13) to in-hospital pulmonary rehabilitation (PR) in individuals with chronic respiratory diseases (CRD). DESIGN: cross-sectional multicentric study. Assessments in individuals attending units on two non-consecutive days. SETTING: 14 Italian in-hospital PR units. PARTICIPANTS: Five hundred forty-seventh individuals (59.2% male, age 72 [65-78] years): 317 with Chronic Respiratory Failure due to various causes (CRF group); 96 with chronic obstructive pulmonary disease without CRF (COPD), 39 Tracheostomized and Ventilated (Tx/V), and 95 with other diseases (Miscellaneous). INTERVENTION: Assessment of RCS-Ev13 before and after the PR program. MAIN OUTCOME MEASURES: RCS-Ev13 and outcome measures: Barthel Index (BI), Barthel Index Dyspnoea (BiD), Medical Research Council Scale for dyspnoea (MRC), COPD Assessment Test (CAT), Short Physical Performance Battery (SPPB), Six-Minute Walking Test (6MWT). RESULTS: The highest RCS-Ev13 admission values (median; IQR) were found in TX/V (17; 15-18) as compared to other groups (8; 7-10, 10; 9-12, 8; 8-10 in COPD, CRF and Miscellaneous respectively, p<0.001). At admission and discharge, RCS-Ev13 correlated strongly with BI, 6MWT, and SPPB and moderately with MRC and BiD (r: 0.43 to 0.60). After the program RCS-Ev13 as well as all outcome measures improved significantly in all groups (p< 0.001 for all). The size of improvement was different among groups according to the different variables. In the overall group the effect size was high for changes in RCS-E v13 (Cohen's d = -2.0984), CAT = (-1.1937), MRC (- 1.0505), BiD (- 0.9364) and SPPB (0.9231) while moderate for 6MWT (0.7670) and BI (0.6574). CONCLUSIONS: RCS-E v13 varies according to different CRDs, is responsive to PR, has good construct and concurrent validity, and correlates with most of the accepted outcome measures of PR. Its scoring may provide useful information on the care burden of individuals undergoing PR.

Effect of Pulmonary Rehabilitation on COPD Assessment Test Items in Individuals Classified as GOLD Group E.

BACKGROUND: A new Global Initiative for Chronic Obstructive Lung Disease (GOLD) classification has been proposed, based also on COPD Assessment Test (CAT). OBJECTIVES: The aim of this large, multicenter, retrospective study was to determine the impact of pulmonary rehabilitation (PR) on CAT items in individuals with COPD, GOLD group E, recovering from an exacerbation (ECOPD). As secondary aims, we evaluated whether gender, associated chronic respiratory failure (CRF), and age might influence results. METHODS: Data of 2,213 individuals with available paired pre- and post-PR CAT were analyzed. Other common outcome measures were also assessed. RESULTS: After PR, total CAT improved from 20.8 ± 7.8 to 12.4 ± 6.9 (p = 0.000), and 1,911 individuals (86.4%) reached the minimal clinically important difference (MCID). All CAT items improved significantly without any significant difference among them. However, item "confidence with disease" improved significantly more in males than in females (p = 0.009). Total CAT and six out of eight items improved significantly more in individuals with CRF than in those without (all p < 0.001). Total CAT and three items improved significantly more in younger than in older individuals (p = 0.023). Only presence of CRF was significantly associated with the probability of improving total CAT more than the MCID. CONCLUSION: In individuals with COPD, GOLD group E, recovering from ECOPD, PR improves all CAT items; however, gender, associated CRF and age may influence the effect size, suggesting the need to evaluate all items in addition to total CAT score.

Perceptual and qualitative voice alterations detected by GIRBAS in patients with Parkinson's disease: is there a relation with lung function and oxygenation?

BACKGROUND: Impairments in respiration, voice and speech are common in people with Parkinson's disease (PD). AIMS: To evaluate the prevalence of dysphonia, assessed by a specific acoustic evaluation and description of the voice by the speech therapist (GIRBAS), and its relation with lung function and oxygenation, in particular cough ability and during the night or exercise desaturation. METHODS: This is a posthoc analysis of a prospective cross-sectional observational study on PD patients collecting anthropometric and clinical data, comorbidities, PD severity, motor function and balance, respiratory function at rest, during exercise and at night, voice function with acoustic analysis and presence of speech disorders, in addition to the GIRBAS scale. Based on GIRBAS Global dysphonia ('G') score, we divided patients into dysphonic (moderate-to-severe deviance from the euphonic condition) vs. no/mild dysphonic and analyzed the relations with respiratory impairments. RESULTS: We analyzed 55 patients and found significant impairments in both respiratory and voice/speech functions. Most patients (85.5%) presented mild-to-severe deviance from the euphonic condition in at least one GIRBAS perceptual element (80% of cases for Global dysphonia) and only 14.5% did not show deviance in all elements simultaneously. At Odds Ratio analysis, the risk of presenting nocturnal desaturation and reduced peak cough expiratory flow was approximately 24 and 8 times higher, respectively, in dysphonic patients vs. those with no/mild dysphonia. CONCLUSION: Perceptual and qualitative evaluation of the voice with GIRBAS showed that mild-to-severe dysphonia was highly prevalent in PD patients, and associated with nocturnal oxygen desaturation and poor cough ability.

Effects of pulmonary rehabilitation in survivors of severe acute respiratory syndrome coronavirus 2. Role of vaccination.

Survivors of severe COVID-19 requiring hospital admission may suffer from short- and long-term sequelae, including disability and reduced physical performance. Vaccination and pulmonary rehabilitation (PR) are effective tools against COVID-19 effects. While the beneficial effect of each of these treatments is known, there are no data about their combined effect. In people admitted to PR hospitals after severe COVID-19 disease, we retrospectively analyzed whether PR outcome might be influenced by vaccination status. Ninety-six individuals were studied (46 vaccinated, 50 unvaccinated). Unvaccinated individuals were younger and less comorbid than vaccinated ones and had needed more intensive care support during the previous hospitalization. Measures of disability and physical performance did not differ between groups at the beginning and at the end of the PR program. However, each group showed a statistically significant improvement in all outcome measures (6-minute walking test, short physical performance battery, Barthel Index). We conclude that vaccination status does not influence the outcome of in-patient PR programs for survivors of severe COVID-19.

Comparison among three different follow-up models for obstructive sleep apnea syndrome patients: focus on the physiotherapist's role.

In obstructive sleep apnea syndrome (OSAS) subjects different follow-up modalities have been proposed to improve adherence to the continuous positive airway pressure (CPAP) device. This retrospective study compares three different health professional approaches dedicated to caring OSAS patients in three consecutive follow-up periods of 15 months each. The three different follow-up models are: i) physician-oriented follow-up (P-F); ii) physiotherapist-oriented follow-up (PT-F); and iii) tele-titration plus PT-oriented follow-up (TT-PT-F). Health personal visits and actions delivered, patients' adherence, CPAP efficacy, and problems under CPAP use were considered for comparison. Data from 122 OSAS patients with a new prescription of CPAP were analyzed: 39 (32.0%) in the P-F, 38 (31.1%) in the PT-F, and 45 (36.9%) in the TT-PT-F period. We found a reduction over time (from 40.9% in P-F to 8.2% in TT-PT-F, p<0.001) in patients missing the 1-year follow-up visit. The PT-F and TT-PT-F lead to a reduction in physician visits in comparison to P-F (5.2% and 8.9% vs 100%, p<0.001) with no differences in time to the first follow-up visit, CPAP efficacy, and patients' adherence among the three periods. More device-related problems were found in the PT-F (57.8%), compared with the PF (25.6%) period (p<0.001); the most common troubles were mask problems evaluated in 26.2% of cases. In conclusion, different follow-up models offer similar efficacy and short-term adherence for CPAP leading to a significant reduction in physician visits under the PT-F with or without tele-titration, being mask problems as the most commonly treated. Further analysis should be useful to define the best cost-efficacy follow-up intervention.

European Respiratory Society statement on long COVID follow-up.

Patients diagnosed with coronavirus disease 2019 (COVID-19) associated with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection frequently experience symptom burden post-acute infection or post-hospitalisation. We aimed to identify optimal strategies for follow-up care that may positively impact the patient's quality of life (QoL). A European Respiratory Society (ERS) Task Force convened and prioritised eight clinical questions. A targeted search of the literature defined the timeline of "long COVID" as 1-6 months post-infection and identified clinical evidence in the follow-up of patients. Studies meeting the inclusion criteria report an association of characteristics of acute infection with persistent symptoms, thromboembolic events in the follow-up period, and evaluations of pulmonary physiology and imaging. Importantly, this statement reviews QoL consequences, symptom burden, disability and home care follow-up. Overall, the evidence for follow-up care for patients with long COVID is limited.

Relationship between perceived and neuromuscular fatigue in COPD patients with chronic respiratory failure with long-term oxygen therapy: a cross-sectional study.

PURPOSE: To evaluate perceived fatigue (PF) and neuromuscular fatigue (NMF) in patients with COPD and chronic respiratory failure (CRF) on long-term oxygen therapy (CRF-COPD group), and the relationships between PF, NMF, patient's characteristics, comparing severe patients with COPD to patients without CRF (COPD group). METHODS: This cross-sectional study compared 19 CRF-COPD patients with 10 COPD patients attending a rehabilitation program. PF was determined by Fatigue Severity Scale (FSS), while dyspnea by the Barthel Dyspnea Index (BDI). We assessed quadriceps NMF via electrical nerve stimulation during and following a Maximal Voluntary Contraction (MVC) detecting changes after a Constant Workload Cycling Test (CWCT) at 80% of the peak power output at exhaustion. RESULTS: CRF-COPD patients showed higher PF (+ 1.79 of FSS score, p = 0.0052) and dyspnea (+ 21.03 of BDI score, p = 0.0023) than COPD patients. After the fatiguing task and normalization for the total work, there was a similar decrease in the MVC (CRF-COPD -1.5 ± 2.4 vs COPD -1.1 ± 1.2% baseline kJ-1, p = 0.5819), in the potentiated resting twitch force (CRF-COPD -2.8 ± 4.7 vs COPD -2.0 ± 3.3% baseline kJ-1, p = 0.7481) and in the maximal voluntary activation (CRF-COPD -0.1 ± 3.9 vs COPD -0.9 ± 1.2 -2.0 ± 3.3% baseline kJ-1, p = 0.4354). FSS and BDI were closely related (R = 0.5735, p = 0.0011), while no correlation between PF and NMF was found. CONCLUSION: Patients with CRF-COPD develop higher levels of perceived fatigue and dyspnea than patients with COPD; while neuromuscular fatigue is similar, suggesting a mismatch between symptoms and neuromuscular dysfunction.

Hidden biases in clinical decision-making: potential solutions, challenges, and perspectives.

Every day, we must make decisions that range from simple and risk-free to difficult and risky. Our cognitive sources' limitations, as well as the need for speed, can frequently impair the quality and accuracy of our reasoning processes. Indeed, cognitive shortcuts lead us to solutions that are sufficiently satisfying to allow us to make quick decisions. Unfortunately, heuristics frequently misguide us, and we fall victim to biases and systematic distortions of our perceptions and judgments. Because suboptimal diagnostic reasoning processes can have dramatic consequences, the clinical setting is an ideal setting for developing targeted interventions to reduce the rates and magnitude of biases. There are several approaches to bias mitigation, some of which may be impractical. Furthermore, advances in information technology have given us powerful tools for addressing and preventing errors in health care. Recognizing and accepting the role of biases is only the first and unavoidable step toward any effective intervention proposal. As a result, our narrative review aims to present some insights on this contentious topic based on both medical and psychological literature.

Noninvasive respiratory support outside the intensive care unit for acute respiratory failure related to coronavirus-19 disease: a systematic review and meta-analysis.

BACKGROUND: Noninvasive respiratory support (NIRS) has been diffusely employed outside the intensive care unit (ICU) to face the high request of ventilatory support due to the massive influx of patients with acute respiratory failure (ARF) caused by coronavirus-19 disease (COVID-19). We sought to summarize the evidence on clinically relevant outcomes in COVID-19 patients supported by NIV outside the ICU. METHODS: We searched PUBMED®, EMBASE®, and the Cochrane Controlled Clinical trials register, along with medRxiv and bioRxiv repositories for pre-prints, for observational studies and randomized controlled trials, from inception to the end of February 2021. Two authors independently selected the investigations according to the following criteria: (1) observational study or randomized clinical trials enrolling ≥ 50 hospitalized patients undergoing NIRS outside the ICU, (2) laboratory-confirmed COVID-19, and (3) at least the intra-hospital mortality reported. Preferred Reporting Items for Systematic reviews and Meta-analysis guidelines were followed. Data extraction was independently performed by two authors to assess: investigation features, demographics and clinical characteristics, treatments employed, NIRS regulations, and clinical outcomes. Methodological index for nonrandomized studies tool was applied to determine the quality of the enrolled studies. The primary outcome was to assess the overall intra-hospital mortality of patients under NIRS outside the ICU. The secondary outcomes included the proportions intra-hospital mortalities of patients who underwent invasive mechanical ventilation following NIRS failure and of those with 'do-not-intubate' (DNI) orders. RESULTS: Seventeen investigations (14 peer-reviewed and 3 pre-prints) were included with a low risk of bias and a high heterogeneity, for a total of 3377 patients. The overall intra-hospital mortality of patients receiving NIRS outside the ICU was 36% [30-41%]. 26% [21-30%] of the patients failed NIRS and required intubation, with an intra-hospital mortality rising to 45% [36-54%]. 23% [15-32%] of the patients received DNI orders with an intra-hospital mortality of 72% [65-78%]. Oxygenation on admission was the main source of between-study heterogeneity. CONCLUSIONS: During COVID-19 outbreak, delivering NIRS outside the ICU revealed as a feasible strategy to cope with the massive demand of ventilatory assistance.

Predictors of Low Physical Function in Patients With COVID-19 With Acute Respiratory Failure Admitted to a Subacute Unit.

OBJECTIVE: To document the level of physical function in patients with coronavirus disease 2019 (COVID-19) recovering from acute respiratory failure and investigate which patient clinical characteristics could predict physical function assessed by the Short Physical Performance Battery (SPPB) test. DESIGN: Cross-sectional study. SETTING: Subacute unit of a Rehabilitation Institute. PARTICIPANTS: Patients with COVID-19 (N=184; aged 18 years or older) who were admitted to a subacute unit to stabilize their condition and recover from acute respiratory failure due to COVID-19. INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: At admission patients underwent the SPPB test, represented by the sum of 3 functional tests, standing balance, 4-meter gait speed, and 5-repetition sit-to-stand motion. Comparisons between 2 SPPB score groups were performed by an unpaired t test; multivariate stepwise linear regression analysis was employed to detect predictors of the SPPB score considering several clinical parameters. RESULTS: Participants were 74±12 years old, 52% were men and with more than 2 comorbidities in 43% of cases. SPPB score was 3.02±3.87 denoting patients' profound physical dysfunction. Normal physical function was detected in only 12% of patients, whereas low, intermediate, and severe impairment was found in 65%, 13%, and 10%, respectively. Age, both invasive and noninvasive ventilation use, and the presence of previous disability were significant predictors of SPPB. Patients without any comorbidities (8%) also exhibited low function (SPPB: 5.67±1.12). CONCLUSIONS: The majority of survivors after COVID-19 experienced acute respiratory failure due to pneumonia and exhibited substantial physical dysfunction influenced by age, mechanical ventilation need, and previous disability. Further studies are needed to evaluate the role of rehabilitation to promote recovery and community reintegration in this population.

Pulmonary Rehabilitation in Patients Recovering from COVID-19.

BACKGROUND: In hospitalized patients recovering from the SARS-coronavirus-2 disease 19 (COVID-19), high prevalence of muscle weakness and physical performance impairment has been observed. OBJECTIVES: The aim of this study was to evaluate the effectiveness of pulmonary rehabilitation in these subjects in a real-life setting. METHODS: Retrospective data analysis of patients recovering from COVID-19, including those requiring assisted ventilation or oxygen therapy, consecutively admitted to an in-patient pulmonary rehabilitation program between April 1 and August 15, 2020. Short Physical Performance Battery (SPPB: primary outcome), Barthel Index (BI), and six-min walking distance were assessed as outcome measures. RESULTS: Data of 140 patients were analyzed. After rehabilitation, patients showed improvements in SPPB {from: (median [IQR]) 0.5 (0-7) to 7 (4-10), p < 0.001} and BI (from 55 [30-90] to 95 [65-100], p < 0.001), as well as in other assessed outcome measures. The proportion of patients unable at admission to stand, rise from a chair and walk was significantly reduced (p < 0.00). CONCLUSIONS: Pulmonary rehabilitation is possible and effective in patients recovering from COVID-19. Our findings may be useful to guide clinicians taking care of patients surviving COVID-19 infection.

Patients recovering from COVID-19 pneumonia in sub-acute care exhibit severe frailty: Role of the nurse assessment.

AIMS AND OBJECTIVES: To document the level of frailty in sub-acute COVID-19 patients recovering from acute respiratory failure and investigate the associations between frailty, assessed by the nurse using the Blaylock Risk Assessment Screening Score (BRASS), and clinical and functional patient characteristics during hospitalisation. BACKGROUND: Frailty is a major problem in patients discharged from acute care, but no data are available on the frailty risk in survivors of COVID-19 infection. DESIGN: A descriptive cross-sectional study (STROBE checklist). METHODS: At admission to sub-acute care in 2020, 236 COVID-19 patients (median age 77 years - interquartile range 68-83) were administered BRASS and classified into 3 levels of frailty risk. The Short Physical Performance Battery (SPPB) was also administered to measure physical function and disability. Differences between BRASS levels and associations between BRASS index and clinical parameters were analysed. RESULTS: The median BRASS index was 14.0 (interquartile range 9.0-20.0) denoting intermediate frailty (32.2%, 41.1%, 26.7% of patients exhibited low, intermediate and high frailty, respectively). Significant differences emerged between the BRASS frailty classes regards to sex, comorbidities, history of cognitive deficits, previous mechanical ventilation support and SPPB score. Patients with no comorbidities (14%) exhibited low frailty (BRASS: median 5.5, interquartile range 3.0-12.0). Age ≥65 years, presence of comorbidities, cognitive deficit and SPPB % predicted <50% were significant predictors of high frailty. CONCLUSIONS: Most COVID-19 survivors exhibit substantial frailty and require continuing care after discharge from acute care. RELEVANCE TO CLINICAL PRACTICE: The BRASS index is a valuable tool for nurses to identify those patients most at risk of frailty, who require a programme of rehabilitation and community reintegration.

Recovering of oxygenation, physical function and disability in patients with Covid-19.

The present case report describes middle-time course of respiratory and physical variables in eight Covid-19 patients who were transferred from ICU of Covid Hub in our subacute Covid-19 unit. Secondly they were admitted in a pulmonary rehabilitation unit and, at discharge, a tele-rehabilitation program was provided as a continuum of care at home. Time course of oxygenation, physical function and disability were recorded. As expected, the acute event produced in these patients a dramatic worsening in oxygenation and physical activities, with a substantial improvement in oxygenation and mild disability after the sub-acute stay. After rehabilitation program, the patients showed additional improvement in particular in physical function. Anyway, this recover was not complete for all patients. The majority of Covid-19 survivors experienced ARF recovered oxygenation, physical function and disability within a median time of 137 days. A minority needs further follow up and rehabilitation maintenance due to incomplete recovery.

The respiratory rehabilitation Maugeri network service reconfiguration after 1 year of COVID-19.

As part of the Italian Health Service the respiratory ICS Maugeri network were reconfigured and several in-hospital programs were suspended to be substituted by workforce and facilities reorganization for acute and post-acute COVID-19 care need. The present review shows the time course variation of respiratory ICS network in terms of admissions diagnosis and outcomes. A comparative review of the admissions and outcome measures data (anthropometric, admission diagnosis, provenience, comorbidities, disability, symptoms, effort tolerance, disease impact, length of stay and discharge destinations) over 1 year period (March 2020-March 2021) was undertaken and compared to retrospective data from a corresponding 1 year (March 2019-March 2020) period to determine the impact of the network relocation on the delivery of pulmonary specialist rehabilitation to patients with complex needs during the pandemic episode. One of the changes implemented at the respiratory Maugeri network was the relocation of the Pulmonary Rehabilitation units from its 351 beds base to a repurposed 247 beds and a reduction in total number of admitted patients (n=3912 in pre-COVID time; n=2089 in post COVID time). All respiratory diagnosis, except COVID sequelae, decreased (chronic respiratory failure-CRF, COPD, obstructive sleep apnoea syndrome-OSAS, interstitial lung disease-ILD, tracheostomized patients and other mixed diseases decreased of 734, 705, 157, 87, 79 and 326 units respectively). During the pandemic time, 265 post COVID sequelae with CRF were admitted for rehabilitation (12.62%), % of patients coming from acute hospital increased, LOS and NIV use remained stable while CPAP indication decreased. Disease impact, dyspnea and effort tolerance as their improvements after rehabilitation, were similar in the two periods.  Only baseline disability, expressed by Barthel index, seems higher in the 2° observation time as its improvement. Hospital deaths and transfers to acute hospitals were higher during pandemic crisis while home destination decreased. This review demonstrated impact of coronavirus pandemic situation, specifically the relocation of the respiratory inpatient rehabilitation wards in a huge Italian network.

Respiratory rehabilitation for patients with COVID-19 infection and chronic respiratory failure: a real-life retrospective study by a Lombard network.

The Lombardy region has been one of the areas most affected by the COVID-19 pandemic since the first months of 2020, providing real-life experiences in the acute phase. It is unclear how the respiratory rehabilitation network responded to this emergency. The aims of this retrospective study were: i) to analyze clinical, functional, and disability data at admission; ii) describe assessment tools and rehabilitative programs; iii) evaluate improvement after rehabilitation. The study was conducted on data collected from ten pulmonary rehabilitation centers in Lombardy, between the period of March 1st 2020 to March 1st 2021, in patients with respiratory failure recovering from COVID-19 both at admission and discharge. The study included demographics, comorbidities, nutritional status, risk of falls, disability status (Barthel index; Short Physical Performance Battery (SPPB); 6 minutes walking test (6MWT), symptoms (dyspnoea with Barthel Dyspnoea and MRC Dyspnoea Scale), length of stay, discharge destination, need for mechanical ventilation, respiratory function, assessment/outcomes indices, and prescribed rehabilitative programs. 413 patients were analyzed. Length of stay in acute and rehabilitative units was less than 30 days. Fifty % of patients used non-invasive ventilation during their stay. Functional status was mildly compromised for forced volumes and oxygenation, while severely compromised for diffusion capacity. Independency was low while physical performance status very low.  At discharge, 318 (77%) patients were sent home, 83 (20.1%) were transferred to an acute unit and 12 (2.9%) passed away. Barthel Index and 6MWT were the most used, while MRC score was the least used outcome parameter. The 5 main rehabilitative activities were walking (90.8 %), transfer from bed to armchair (77.5%), limb mobilization in bed (76%), balance (71.2%), and cycle-ergometer or treadmill (43.1%). A huge difference was found in admission, discharge, and delta change among different rehabilitative centers. When available, all outcomes showed a significant improvement. With the limitation of a retrospective study with a clear amount of missing data, COVID-19 subjects admitted to rehabilitative centers presented a reduced physical performance, symptoms of dyspnoea, and severe disability. The 6MWT and Barthel index were the most used measurement.

Effect of nocturnal EPAP titration to abolish tidal expiratory flow limitation in COPD patients with chronic hypercapnia: a randomized, cross-over pilot study.

BACKGROUND: Tidal expiratory flow limitation (EFLT) promotes intrinsic PEEP (PEEPi) in patients with chronic obstructive pulmonary disease (COPD). Applying non-invasive ventilation (NIV) with an expiratory positive airway pressure (EPAP) matching PEEPi improves gas exchange, reduces work of breathing and ineffective efforts. We aimed to evaluate the effects of a novel NIV mode that continuously adjusts EPAP to the minimum level that abolishes EFLT. METHODS: This prospective, cross-over, open-label study randomized patients to one night of fixed-EPAP and one night of EFLT-abolishing-EPAP. The primary outcome was transcutaneous carbon dioxide pressure (PtcCO2). Secondary outcomes were: peripheral oxygen saturation (SpO2), frequency of ineffective efforts, breathing patterns and oscillatory mechanics. RESULTS: We screened 36 patients and included 12 in the analysis (age 72 ± 8 years, FEV1 38 ± 14%Pred). The median EPAP did not differ between the EFLT-abolishing-EPAP and the fixed-EPAP night (median (IQR) = 7.0 (6.0, 8.8) cmH2O during night vs 7.5 (6.5, 10.5) cmH2O, p = 0.365). We found no differences in mean PtcCO2 (44.9 (41.6, 57.2) mmHg vs 54.5 (51.1, 59.0), p = 0.365), the percentage of night time with PtcCO2 > 45 mm Hg was lower (62(8,100)% vs 98(94,100)%, p = 0.031) and ineffective efforts were fewer (126(93,205) vs 261(205,351) events/hour, p = 0.003) during the EFLT-abolishing-EPAP than during the fixed-EPAP night. We found no differences in oxygen saturation and lung mechanics between nights. CONCLUSION: An adaptive ventilation mode targeted to abolish EFLT has the potential to reduce hypercapnia and ineffective efforts in stable COPD patients receiving nocturnal NIV.

Adapted physical activity and therapeutic exercise in late-onset Pompe disease (LOPD): a two-step rehabilitative approach.

Aerobic exercise, training to sustain motor ability, and respiratory rehabilitation may improve general functioning and quality of life (QoL) in neuromuscular disorders. Patients with late-onset Pompe disease (LOPD) typically show progressive muscle weakness, respiratory dysfunction and minor cardiac involvement. Characteristics and modalities of motor and respiratory rehabilitation in LOPD are not well defined and specific guidelines are lacking. Therefore, we evaluated the role of physical activity, therapeutic exercise, and pulmonary rehabilitation programs in order to promote an appropriate management of motor and respiratory dysfunctions and improve QoL in patients with LOPD. We propose two operational protocols: one for an adapted physical activity (APA) plan and the other for an individual rehabilitation plan, particularly focused on therapeutic exercise (TE) and respiratory rehabilitation.

Intrinsic Dynamic Positive End-Expiratory Pressure in Stable Patients with Chronic Obstructive Pulmonary Disease.

BACKGROUND: Assessment of intrinsic dynamic positive end-expiratory pressure (PEEPi,dyn) may be clinically important in stable patients with chronic obstructive pulmonary disease (COPD), but epidemiological data are scant. OBJECTIVES: The aim of our study was (i) to assess the PEEPi,dyn in a large population of stable patients with COPD and (ii) to evaluate the correlations with some noninvasive measurements routinely assessed. METHOD: Retrospective analysis of lung mechanics, dynamic volumes, arterial blood gases, dyspnoea by means of the Medical Research Council (MRC) scale, the COPD Assessment Test score, and maximal inspiratory/expiratory pressures in 87 hypercapnic and 62 normocapnic patients. RESULTS: The mean PEEPi,dyn was significantly higher in hypercapnic than normocapnic patients (2.8 ± 2.2 vs. 1.9 ± 1.6 cm H2O, respectively, p = 0.0094). PEEPi,dyn did not differ according to Global Initiative for Chronic Obstructive Lung Disease stage, MRC score, or use or not of long-term oxygen therapy. There were significant although weak correlations between PEEPi,dyn and airway obstruction, hyperinflation, respiratory muscle function, arterial CO2 tension, and number of exacerbations/year. The transdiaphragmatic pressure was the strongest variable associated to PEEPi,dyn (R = 0.5713, p = 0.001). CONCLUSION: In stable patients with COPD, PEEPi,dyn is higher in hypercapnic patients and weakly correlated to noninvasive measures of lung and respiratory muscle function.

Joint Statement on the Role of Respiratory Rehabilitation in the COVID-19 Crisis: The Italian Position Paper.

Due to the exponential growth of the number of subjects affected by coronavirus disease 2019 (COVID-19), the entire Italian health care system had to respond promptly and in a very short time with the need of semi-intensive and intensive care units. Moreover, trained dedicated COVID-19 teams consisting of physicians were coming from different specialties (intensivists or pneumologists and infectiologists), while respiratory therapists and nurses have been recruited to work on and on without rest. However, due to still limited and evolving knowledge of COVID-19, there are few recommendations concerning the need in respiratory rehabilitation and physiotherapy interventions. The presentation of this paper is the result of a consensus promoted by the Italian societies of respiratory health care professionals who contacted pulmonologists directly involved in the treatment and rehabilitation of COVID-19. The aim was to formulate the more proper and common suggestions to be applied in different hospital settings in offering rehabilitative programs and physiotherapy workforce planning for COVID-19 patients. Two main areas of intervention were identified: organization and treatment, which are described in this paper to face the emergency.

How the COVID-19 infection tsunami revolutionized the work of respiratory physiotherapists: an experience from Northern Italy.

Due to COVID-19 outbreak, to lighten the burden of acute and critical care hospitals, some respiratory rehabilitation departments have been used to host patients with COVID-19 in the post-acute phase. This new and unexpected situation required a change of roles and scheduling of the rehabilitation teams. In this manuscript we describe the unexpected and urgent organizational change of the Cardio-Pulmonary Rehabilitation (CPR) service during the COVID-19 emergency in a Northern Italian rehabilitation hospital, focusing on the Respiratory Physiotherapists' (RPTs) role. A quick three-days complete reorganization of the entire hospital was needed. A COVID-19 care team including a multidisciplinary panel of physicians, nurses, and RPTs was quickly performed to manage 90 beds for post acute patients with COVID-19. Within the team, the RPTs changed their shifts, so as to be available 16h per day, 7 days out of 7. Remodelled tasks in charge of RPTs were: oxygen therapy daily monitoring, non invasive ventilation (NIV) and continuous positive airways pressure (CPAP) delivery, pronation and postural changes to improve oxygenation, reconditioning with leg/arm cranking and exercises, initial and final patients' functional assessment by short-physical performance battery (SPPB) and 1-minute sit-to-stand test (1-STS) to evaluate motor conditions and exercise-induced oxygen desaturation. Three "what-to-do" algorithms were developed to guide: i) oxygen de-escalation by reducing inhaled fraction of oxygen (FiO2); ii) oxygenation improvement through the use of Venturi mask; iii) reconditioning and physical activity. One-hundred seventy patients were treated in one month. As main topics, RPTs have been involved in oxygen therapy management in almost a third of the admitted patients, reconditioning exercises in 60% of the cases, and initial and final functional motor capacity assessment in all patients. Details of activities performed by the RPT in one typical working day are also shown. Our reorganization has exploited the professional skills and clinical expertise of the RPTs. This re-organization can provide practical insights to other facilities that are facing this crisis, and may be a starting point for implementing post-COVID-19 rehabilitation. Future studies will have to improve and review this organization.
