Pulmonary Rehabilitation Outcomes of Post-Acute COVID-19 Patients during Different Waves of the Pandemic.

(1) Background: Between the beginning of the coronavirus pandemic and summer 2022, we distinguished four pandemic waves, with different characteristics of the affected patients. This study investigated the impact of patient characteristics on the outcome of inpatient pulmonary rehabilitation (PR). (2) Methods: Using a prospective approach, the characteristics of post-acute COVID-19 patients of the different waves who participated in inpatient PR were compared based on their assessments and results collected as part of PR (Cumulative Illness Rating Scale (CIRS), six-minute walk test (6-MWT), Pulmonary Function Testing (PFT), and Functional Independent Measurement (FIM). (3) Results: A total of 483 patients were included in the analysis (Wave 1 n = 51, Wave 2 n = 202, Wave 3 n = 84, Wave 4 n = 146). Compared to Wave 3 + 4, patients of Wave 1 + 2 were older (69 vs. 63 years; p < 0.001), had a significantly lower CIRS (13.0 vs. 14.7 points; p = 0.004), had significant better PFT (FVC: 73 vs. 68%pred; p = 0.009; DLCOSB: 58 ± 18 vs. 50 ± 17%pred; p = 0.001), and showed significantly more comorbidities (2.0 vs. 1.6 n/pers.; p = 0.009). Wave 3 + 4 showed significantly greater improvements according to the 6-MWT (147 vs. 188 m; p < 0.001) and the FIM (5.6 vs. 21.1 points; p < 0.001). (4) Conclusions: Patients of the COVID-19 infection waves differed significantly according to their anthropometric data, incidence of comorbidities, and impact of the infection. All cohorts achieved clinically relevant and significant functional improvements during PR, with significant higher improvements in Wave 3 + 4.

Clinical Effects of Pulmonary Rehabilitation in Very Old Patients with COPD.

BACKGROUND: Pulmonary rehabilitation (PR) improves physical and mental performance as well as quality of life in patients with chronic obstructive pulmonary disease (COPD). However, data on outcomes in very old patients are insufficient. We analyzed whether the elderly with COPD benefit in a similar way to younger patients from participation in an inpatient PR according to the assessments usually collected. METHODS: Data from 3173 patients with COPD were retrospectively analyzed. Patients were referred to PR at the Zurich RehaZentren, Switzerland, between January 2013 and December 2019. PR was performed 6 days per week with an average duration of 18.85 days. Functional Independence Measurement (FIM), Feeling Thermometer (FT), and 6-Minute Walk Test (6MWT) were recorded on admission and discharge. RESULTS: In all age groups, the 6MWT and FT improved significantly. FIM results also showed a significant increase. The results of the different age groups showed no significant differences in percentage improvements according to the assessments that were considered. CONCLUSIONS: All patient groups with COPD, even the oldest (>85 years), benefited from PR regardless of their age and according to the assessments. Prospective studies are needed to support this hypothesis.

Using a smartphone application maintains physical activity following pulmonary rehabilitation in patients with COPD: a randomised controlled trial.

BACKGROUND: Evidence suggests that patients with COPD struggle to maintain improved physical activity (PA) after completing pulmonary rehabilitation (PR). Smartphone applications (apps) providing a comprehensive training programme have conferred healthy benefits. This study was conducted to determine whether regular usage of an app maintains PA following PR. METHODS: Patients with stage II-IV COPD were enrolled in a 6-month trial following PR. After the screening period, participants were randomised into the Kaia COPD app group (intervention group (IG)) or the control group (CG). The primary outcome was PA (daily steps), measured using an activity tracker. Secondary outcomes included the COPD Assessment Test (CAT), the Chronic Respiratory Disease Questionnaire (CRQ) and the 1 min Sit-to-Stand Test (STST). RESULTS: Sixty participants completed the study. The median steps from baseline to 6 months were significantly different between the groups, in favour of the IG (-105.3, IQR -1970.1 to 2105.8, vs CG -1173.0, IQR -3813.1 to -93.8; p=0.007). CAT was significantly decreased in the IG (15.1±8.6 vs 19.7±6.4, p=0.02), whereas the CRQ subdomains for dyspnoea (4.5±1.7 vs 3.7±1.3, p=0.033) and fatigue (4.5±1.4 vs 3.5±1.3, p=0.028) improved significantly in the IG. The STST at 6 months was not significant. Sleep duration and sleep efficiency showed no significant differences between the two groups at any time. CONCLUSIONS: A comprehensive program by using the Kaia app following PR maintained PA and improved symptoms in patients with COPD at 6 months. The app might be an important accessory tool for enhanced COPD care. TRIAL REGISTRATION NUMBER: DRKS00017275.

Inhalation Therapy with Nebulized Capsaicin in a Patient with Oropharyngeal Dysphagia Post Stroke: A Clinical Case Report.

Dysphagia and aspiration risk are common sequelae of stroke, leading to increased risk of stroke-associated pneumonia. This is often aggravated by stroke-related impairment of cough, the most immediate mechanical defense mechanism against aspiration. In humans, reflex cough can be repeatedly and safely elicited by inhalation of nebulized capsaicin, a compound contained in chili peppers. Could this cough-eliciting property of capsaicin support the recovery of stroke survivors who present with dysphagia and aspiration risk? We present a clinical case report of a 73-year-old man, admitted to inpatient stroke rehabilitation following a right middle cerebral artery infarct with subsequent dysphagia and hospital-acquired pneumonia. A course of daily inhalation therapy with nebulized capsaicin was initiated, triggering reflex coughs to support secretion clearance and prevent recurrence of pneumonia. Clinical observations in each inhalation therapy session demonstrate good patient response, safety and tolerability of nebulized capsaicin in this mode of application. Repeated Fiberoptic Endoscopic Evaluation of Swallowing (FEES) assessments show concurrent improvement in the patient's swallowing status. Inhalation therapy with nebulized capsaicin may offer a viable treatment to facilitate coughing and clearing of secretions, and to minimize aspiration and risk of aspiration-related pneumonia post stroke. Further investigation in a randomized controlled trial design is warranted.

Clinical and Functional Predictors of Response to a Comprehensive Pulmonary Rehabilitation in Severe Post-COVID-19 Patients.

BACKGROUND: Pulmonary rehabilitation (PR) following severe and very severe COVID-19 infection is known to be effective, according to typical assessments. However, not all patients benefit from PR to the same extent. This analysis aimed to identify the impact of different factors on PR outcomes in post-COVID-19 patients. METHODS: This prospective observational study included 184 post-COVID-19 patients. The achievement of the predicted reference walking distance (6 min walking distance (6-MWD)) served as a parameter with which to identify responders and non-responders to PR. Several parameters (e.g., Functional Independent Measurement (FIM); pulmonary function testing (Forced Vital Capacity, FVC); 6MWD) were assessed in order to estimate their impact on PR success. Logistic regression models and classification and regression trees were used for multivariate analysis. RESULTS: A total of 94 patients (51%) reached their reference 6MWD by the end of PR. FVC (0.95 (0.93-0.97)), 6MWD at admission (0.99 (0.99-1.00)), and FIM motoric (0.96 (0.93-0.99)) correlated with the risk not reaching the reference distance. The most important variable was the 6MWD at admission. Classification and regression tree identified 6MWD ≥ 130 m at admission and FVC predicted of >83% as the strongest predictor for reaching predicted 6-MWD. CONCLUSION: Post-COVID-19 patients with lower 6MWD, lower motoric FIM scores and lower FVC at admission have a high risk of not reaching their target values of physical performance despite intensive rehabilitation. As well as identifying them, it is of utmost importance to develop optimal PR concepts for these patients.

Predictive Value of Cough Frequency in Addition to Aspiration Risk for Increased Risk of Pneumonia in Dysphagic Stroke Survivors: A Clinical Pilot Study.

BACKGROUND: Post-stroke dysphagia leads to increased risk of aspiration and subsequent higher risk of pneumonia. It is important to not only diagnose post-stroke dysphagia early but also to evaluate the protective mechanism that counteracts aspiration, i.e., primarily cough. The aim of this study was to investigate the predictive value of cough frequency in addition to aspiration risk for pneumonia outcome. METHODS: This was a single-center prospective observational study. Patients with first-ever strokes underwent clinical swallowing evaluation, fibreoptic endoscopic evaluation of swallowing (FEES), and overnight cough recording using LEOSound® (Löwenstein Medical GmbH & Co. KG, Bad Ems, Germany ). Penetration-Aspiration Scale (PAS) ratings and cough frequency measurements were correlated with incidence of pneumonia at discharge. RESULTS: 11 women (37%) and 19 men (63%), mean age 70.3 years (SD ± 10.6), with ischemic stroke and dysphagia were enrolled. Correlation analysis showed statistically significant relationships between pneumonia and PAS (r = 0.521; p < 0.05), hourly cough frequency (r = 0,441; p < 0.05), and categories of cough severity (r = 0.428 p < 0.05), respectively. Logistic regression showed significant predictive effects of PAS (b = 0.687; p = 0.014) and cough frequency (b = 0.239; p = 0.041) for pneumonia outcome. CONCLUSION: Cough frequency in addition to aspiration risk was an independent predictor of pneumonia in dysphagic stroke survivors.

Effects of a Comprehensive Pulmonary Rehabilitation in Severe Post-COVID-19 Patients.

BACKGROUND: Severe COVID-19 infection often leads to impairments requiring pulmonary rehabilitation (PR) following the acute phase. Little is known about the efficacy of PR in these patients. We therefore compared post-COVID-19 patients (PG) referred to PR patients with other lung diseases (LG). METHODS: 99 PG were admitted to PR. In a prospective design, the results of PG were collected and compared to the results of LG of 2019 (n = 419) according to Functional Independence Measurement (FIM), Cumulative Illness Rating Scale (CIRS), 6-min walk test (6-MWT), duration of PR, and Feeling Thermometer (FT). RESULTS: According to age, sex, and CIRS, both groups showed no significant differences. The improvements in the 6-MWT in the pre to post comparison were on average 180 (±101) meters for PG and 102 (±89) meters for LG (p < 0.001). FT showed a significant enhancement for PG of 21 (±14) points and for LG of 17 (±16) points (p < 0.039), while FIM significantly increased by 11 (±10) points in PG and 7 (±8) points in LG (p < 0.001). CONCLUSIONS: Comprehensive PR in PG is very effective according to the results in FIM, 6-MWT and FT. Therefore, we recommend PR following severe post-COVID-19 infections.

Reassessment of Poststroke Dysphagia in Rehabilitation Facility Results in Reduction in Diet Restrictions.

BACKGROUND: Dysphagia assessment in postacute stroke patients can decrease the incidence of complications like malnutrition, dehydration, and aspiration pneumonia. It also helps to avoid unnecessary diet restrictions. The aim of this study is to verify if regular reassessment of dysphagia would change the diet management of postacute stroke patients in rehabilitation settings. METHODS: This single-center retrospective study included 63 patients referred to an inpatient neurological rehabilitation center between 2018-2019. A standardized clinical swallowing evaluation and Fiberoptic Endoscopic Evaluation of Swallowing (FEES) were performed. Diet level according to Functional Oral Intake Scale (FOIS) was evaluated. As the primary endpoint, the FOIS values based on diagnostic procedures were assessed at hospital discharge, rehabilitation admission, and after FEES. RESULTS: 19 women (30%) and 44 men (70%), with a mean age of 75 y (SD ± 10.08), were enrolled. The intergroup ANOVA revealed significant differences (p < 0.001) between dietary prescriptions in an acute care setting and following clinical and endoscopic reassessment in the rehabilitation center. Diet recommendations changed in 41 of 63 (65%) enrolled patients (p < 0.001). CONCLUSION: Instrumental diagnostic by FEES during the early convalescence period of stroke patients leads to clinically relevant changes to diet restrictions and lower rates of pneumonia. Our findings underline the need for regular and qualitative dysphagia diagnostics in stroke patients participating in neurological rehabilitation.

COVID-19 Outbreak During Inpatient Rehabilitation: Impact on Settings and Clinical Course of Neuromusculoskeletal Rehabilitation Patients.

OBJECTIVE: The COVID-19 pandemic affects a large number of patients. The impact on feasibility and outcome of rehabilitation during COVID-19 actually remains unclear. Nosocomial infection of healthcare workers or hospitalized patients is common, and prevention of nosocomial infections during rehabilitation is challenging. Therefore, we analyzed a cohort of nosocomial infected COVID-19 patients in a single-center inpatient rehabilitation clinic and described performance and outcome. DESIGN: The cohort (N = 27) describes patients with nosocomial SARS-CoV-2 infection while participating in neuromusculoskeletal rehabilitation. Infection was caused by an initially unidentified so-called superspreader. We compared this cohort with all neuromusculoskeletal rehabilitation inpatients of 2019 (comparison group). Normally distributed continuous variables were presented as mean with standard deviation and the t test was used for comparison between groups. Linear regression was used to assess the impact of COVID-19 on Functional Independence Measure at discharge. RESULTS: COVID-19 patients were mostly male (66.7%) with an age of 71.5 ± 12.3 yrs. Age, sex, and cumulated comorbidities of the comparison group (n = 786) were not different from the COVID-19 group. A total of 92.6% of COVID-19 patients had a mild or moderate course, two patients had to be referred to acute hospital because of respiratory failure, and one of these patients died in the acute hospital. After implementation of a strict hygiene concept, no further nosocomial COVID-19 infections were detected. The rehabilitation duration was significantly longer in the COVID-19 group (54.2 ± 23.6 days vs. 32.1 ± 17.7 days, P < 0.001). Daily therapy duration was 132.3 ± 44 mins before SARS-CoV-2 infection and reduced to 81.9 ± 27.3 mins during COVID-19 (P < 0.001). After discontinuation of isolation measures, therapy duration increased significantly (99.3 ± 70.2 mins, P < 0.05).The baseline Functional Independence Measure score was higher in the COVID-19 group (91.93 ± 25.64 points vs. 82.98 ± 22.73 points) and Functional Independence Measure improvements were lower in COVID-19 patients than in the 2019 comparison group (6.96 ± 8.96 points vs. 20.3 ± 15.98 points, P < 0.001). COVID-19 infection itself had a strong negative impact on Functional Independence Measure change as identified by regression analysis. Linear regression analysis showed that COVID-19 reduced the Functional Independence Measure at discharge by 8.9 points (95% CI = -14.725 to -3.097, P = 0.003) after correction for Functional Independence Measure at admission, age, sex, and morbidity index at admission. CONCLUSIONS: COVID-19 had a strong negative impact on rehabilitation benefits as assessed by Functional Independence Measure. Neuromusculoskeletal rehabilitation could be continued, but all patients received less therapy minutes during isolation. After implementation of a strict COVID-19-specific hygiene concept, no further infections were detected.

Feasibility and Efficacy of Cardiopulmonary Rehabilitation After COVID-19.

The COVID-19 pandemic affects a large number of patients with a rapid progression of respiratory failure often requiring hospitalization or intensive care unit treatment in some patients. Survivors of severe COVID-19 experience persistent weakness and cardiorespiratory failure. Feasibility and potential benefit of cardiopulmonary rehabilitation after COVID-19 remains unclear. Therefore, we retrospectively analyzed a cohort of COVID-19 patients in a single-center inpatient rehabilitation clinic and describe performance and outcome during cardiopulmonary rehabilitation.Patients were referred from acute care hospitals for rehabilitation after severe COVID-19. The cohort (N = 28) was divided in ventilated or not ventilated patients for further analysis. Fifty percent were female, the mean age was 66 yrs, and patients stayed in the acute hospital for 19.3 ± 10.7 days before referral for cardiopulmonary rehabilitation. Seventeen patients (61%) needed previous intensive care unit treatment in the acute care hospital. Risk factors, assessments, and questionnaires on admission were comparable in both groups. Significant enhancements were observed in 6-min walking test and feeling thermometer, which were independent of previous ventilation status.In conclusion, comprehensive cardiopulmonary rehabilitation after COVID-19 is safe, feasible, and effective. Improvements in physical performance and subjective health status were independent of previous ventilation.
