Cognitive behavioural interventions led by a physiotherapist in chronic non-specific low back pain: A systematic review and meta-analysis.

BACKGROUND: The effectiveness of physiotherapist-led Cognitive Behavioural Interventions (CBI) with or without physiotherapy is still unclear. OBJECTIVE: This systematic review (PROSPERO registration number CRD42022321073) aims to determine the effectiveness of physiotherapist-led CBI with or without physiotherapy in comparison to physiotherapy alone on quality of life, disabilities and catastrophization. METHODS: MEDLINE, Web of Science, Science Direct, and PEDro were searched for randomized controlled trials that investigate the use of CBI versus conventional physiotherapy in chronic NSLBP. To be included CBI had to be performed by a physiotherapist. The primary and secondary outcomes were respectively quality of life and disability. RESULTS: Fourteen studies were included in qualitative analysis, in which 4 did not meet the PEDro score of 6 or higher. Pooled standardized mean differences from 3 studies showed no difference in quality of life between groups for mental and physical sub-scores at 3 months (SMD 0.02, 95% CI -0.17 to 0.21 and SMD 0.07, 95% CI -0.12 to 0.26 respectively). Pooled standardized mean differences from 9 studies showed no difference in disability between groups at 3, 6 and 12 months (SMD = - 0.40, CI 95% -0.80 to 0.01; SMD -0.18, CI 95% = -0.41 to 0.05; and SMD -0.24, CI 95% = -0.48 to 0.00 respectively). CONCLUSION: Results of CBI, especially cognitive functional therapy, seem promising in disability management despite a substantial heterogeneity. Furthermore, we found no difference in quality of life.

Effectiveness of exercise training on the dyspnoea of individuals with long COVID: A randomised controlled multicentre trial.

BACKGROUND: COVID-19-related acute respiratory distress syndrome (CARDS) is a severe evolution of the Sars-Cov-2 infection and necessitates intensive care. COVID-19 may subsequently be associated with long COVID, whose symptoms can include persistent respiratory symptoms up to 1 year later. Rehabilitation is currently recommended by most guidelines for people with this condition. OBJECTIVES: To evaluate the effects of exercise training rehabilitation (ETR) on dyspnoea and health-related quality of life measures in people with continuing respiratory discomfort following CARDS. METHODS: In this multicentre, two-arm, parallel, open, assessor-blinded, randomised controlled trial, we enroled adults previously admitted with CARDS to 3 French intensive care units who had been discharged at least 3 months earlier and who presented with an mMRC dyspnoea scale score > 1. Participants received either ETR or standard physiotherapy (SP) for 90 days. The primary outcome was dyspnoea, as measured by the Multidimensional Dyspnoea Profile (MDP), at day 0 (inclusion) and after 90 days of physiotherapy. Secondary outcomes were the mMRC and 12-item Short-Form Survey scores. RESULTS: Between August 7, 2020, and January 26, 2022, 487 participants with CARDS were screened for inclusion, of whom 60 were randomly assigned to receive either ETR (n = 27) or SP (n = 33). Mean MDP following ETR was 42% lower than after SP (26.15 vs. 44.76); a difference of -18.61 (95% CI -27.78 to -9.44; p<10-4). CONCLUSION: People who were still suffering from breathlessness three months after being discharged from hospital with CARDS had significantly improved dyspnoea scores when treated with ETR therapy for 90 days unlike those who only received SP. Study registered 29/09/2020 on Clinicaltrials.gov (NCT04569266).

Diaphragm function in patients with sepsis and septic shock: A longitudinal ultrasound study.

BACKGROUND: Previous literature on the determinants of diaphragm dysfunction in septic patients is limited. The goal of this study is to assess diaphragm dysfunction in terms of its prevalence and its potential associated factors in septic intensive care unit (ICU) patients. METHODS: This prospective and observational study was conducted between June 2015 and July 2019. Ultrasound measures of diaphragm thickness were performed daily on septic patients. The primary outcome was the prevalence of diaphragm dysfunction at baseline and during the ICU stay. The secondary outcome was the diaphragm thickness. Possible associated factors were prospectively recorded. RESULTS: Fifty patients were enrolled in the study. The prevalence of diaphragm dysfunction was 58%. No diaphragm atrophy was found during the ICU stay. Diaphragm dysfunction was associated with the alteration of consciousness, intra-abdominal sepsis, hypnotics and opioids, and mechanical ventilation. Administration of hypnotics, opioids, and steroids was associated with a decreased diaphragm thickening fraction. Diaphragm dysfunction had no impact on patient outcomes. CONCLUSIONS: Our data reveal a high prevalence of diaphragm dysfunction in septic patients at the onset of sepsis. Administration of hypnotics, opioids, and steroids was associated with the alteration of diaphragm function as well as intra-abdominal sepsis.

Thoracic ultrasound influences physiotherapist's clinical decision-making in respiratory management of critical care patients: a multicentre cohort study.

BACKGROUND: The potential influence of thoracic ultrasound on clinical decision-making by physiotherapists has never been studied. The aim of this study was to assess the impact of thoracic ultrasound on clinical decision-making by physiotherapists for critical care patients. METHODS: This prospective, observational multicentre study was conducted between May 2017 and November 2020 in four intensive care units in France and Australia. All hypoxemic patients consecutively admitted were enrolled. The primary outcome was the net reclassification improvement (NRI), quantifying how well the new model (physiotherapist's clinical decision-making including thoracic ultrasound) reclassifies subjects as compared with an old model (clinical assessment). Secondary outcomes were the factors associated with diagnostic concordance and physiotherapy treatment modification. RESULTS: A total of 151 patients were included in the analysis. The NRI for the modification of physiotherapist's clinical decisions was-40% (95% CI (-56 to -22%), p=0.02). Among the cases in which treatment was changed after ultrasound, 41% of changes were major (n=38). Using a multivariate analysis, the physiotherapist's confidence in their clinical diagnosis was associated with diagnostic concordance (adjusted OR=3.28 95% CI (1.30 to 8.71); p=0.014). Clinical diagnosis involving non-parenchymal conditions and clinical signs reflecting abolished lung ventilation were associated with diagnostic discordance (adjusted OR=0.06 95% CI (0.01 to 0.26), p<0.001; adjusted OR=0.26 95% CI (0.09 to 0.69), p=0.008; respectively). CONCLUSION: Thoracic ultrasound has a high impact on the clinical decision-making process by physiotherapists for critical care patients.

Diagnostic accuracy of diaphragm ultrasound to predict weaning outcome: A systematic review and meta-analysis.

BACKGROUND: The accuracy of diaphragm ultrasound for predicting weaning outcome is still debated, despite the publication of numerous studies evaluating this issue. OBJECTIVE: The aim of this systematic review and meta-analysis was to assess the diagnostic accuracy of diaphragm ultrasound for predicting weaning failure in critically ill patients. DESIGN AND DATA SOURCES: MEDLINE, Science direct, Cochrane Library, EMBASE and CENTRAL were searched. Two investigators independently selected studies that met the inclusion criteria, and three extracted data and performed a bias analysis using the Quality Assessment of Diagnostic Accuracy Studies-2 instrument. A bivariate model was used to estimate the pooled results for sensitivity, specificity and diagnostic odds ratio. Sources of heterogeneity were explored, and subgroup analyses were performed. RESULTS: Twenty-eight studies were included in the systematic review, from which 16 studies (816 patients in total) were included in the meta-analysis. The pooled sensitivity, specificity and area under the summary receiver operator characteristic curve were 0.70 (95% CI 0.57-0.80), 0.84 (95% CI 0.73-0.91), and 0.82 (95% Cl 0.78-0.85) for diaphragm thickening fraction, respectively, and 0.71 (95% CI 0.61-0.79), 0.80 (95% CI 0.73-0.86), and 0.82 (95% Cl 0.79-0.86) for diaphragm excursion, respectively. There was substantial heterogeneity among the studies. Meta-regression highlighted significant effects of prevalence of extubation failure, cut-off and risk of bias in flow and timing of the study on diaphragm ultrasound accuracy. By excluding outlier and influential studies, sensitivity was lower and specificity higher for diaphragm thickening fraction. CONCLUSION: The specificity of diaphragm ultrasound for predicting the risk of extubation failure in critically ill patients was moderate-to-high. However, sensitivity was low because weaning is also affected by non-diaphragm-related factors. Further research in subgroups of critically ill patients applying a homogeneous definition of weaning and uniformly conducted measure is needed to assess the accuracy of diaphragm ultrasound. CLINICAL TRIAL REGISTRATION: Registered on http://www.crd.york.ac.uk/PROSPERO as CRD42017058028. Tweetable abstract: Diaphragm ultrasound predicts extubation failure with high specificity. Absence of diaphragm dysfunction does not imply no risk of extubation failure.

Prone position in wards for spontaneous breathing Covid-19 patients: a retrospective study.

The pandemic of coronavirus disease 2019 (Covid-19) caused a large number of non-ventilated hypoxemic patients to require the use of prone position. The aim of this study is to measure the efficiency and tolerance of prone positioning in ward hypoxemic patients treated for Covid-19. This retrospective study included confirmed Covid-19 hypoxemic patients treated by at least one prone position session. Primary outcome was pulse oximetry over inspired oxygen fraction ratio (SpO2/FiO2) before, during, and after prone position. Secondary outcomes were failure, adverse events, and poor tolerance rate. Twenty-seven patients were included. During first, second and third sessions, SpO2/FiO2 ratio was significantly higher during posture than before (p < 0.0001, p < 0.01, and p < 0.001 respectively). Eighteen patients were responders (defined as an improvement of SpO2/FiO2 of more than 50) during the first posture and have a shorter length of hospital stay than non-responder patients. Failure rate was 5%, and poor tolerance and adverse events rates were 8% and 7% respectively. Our study found that prone position in wards improved alveolar exchange during posture and is well tolerated. This technique could be used in any medical ward.
