A retrospective study of physiotherapy management for patients with pneumonia requiring invasive ventilation in a single-center Australian ICU.

Background: Pneumonia is a frequent diagnosis for patients admitted to Australian intensive care units (ICUs) for invasive ventilation. Physiotherapists in ICU provide interventions to enhance respiratory function and physical recovery. Objective: This retrospective cohort study aimed to describe physiotherapy management of adults with pneumonia who require invasive mechanical ventilation in a single Level 3 ICU in a quaternary teaching hospital. Methods: All adults admitted with a medical diagnosis of pneumonia requiring invasive mechanical ventilation over a two-year period were included. Demographic and clinical data, including APACHE II score, ventilator-free days (VFDs) to day 28, ICU length of stay (LOS), and type and frequency of physiotherapy episodes of care delivered in ICU, were collected from electronic medical records. Correlations between VFDs to day 28 and the frequency of physiotherapy interventions delivered per subject were examined using Spearman's rho analysis. Results: From 208 records screened, 66 subjects with an ICU admission diagnosis of pneumonia, who required invasive mechanical ventilation, were included. Median (IQR) ICU LOS was 10 (5-17) days, and mortality rate was 15.2% ( n = 10 ). The cohort had a median of 20.5 (IQR 2-25) VFDs to day 28. Community-acquired pneumonia (66.7%, n = 44 ) was the most frequent type of pneumonia diagnosis. There were 1110 episodes of physiotherapy care, with patients receiving a median of 13.5 (IQR 6.8-21.3) episodes during their ICU stay, with a median rate of 1.2 (IQR 1.0-1.6) episodes per day. Over 96.7% of patients with pneumonia received physiotherapy treatment during their ICU stay. Overall, physiotherapy treatments consisting only of respiratory techniques were most commonly provided (55.1%, n = 612 ). Airway suctioning (92.4%, n = 61 ), patient positioning (72.7%, n = 48 ) or positioning advice to nurses (77.3%, n = 51 ), and hyperinflation techniques (63.6%, n = 42 ) were among the respiratory techniques most delivered. Conclusion: This study described the current intensive care physiotherapy management in a single center for adults with pneumonia who required invasive mechanical ventilation, demonstrating that respiratory physiotherapy interventions are often provided for this ICU patient cohort. Further research is warranted to determine the efficacy of respiratory physiotherapy interventions to justify their use for ICU patients with pneumonia receiving invasive mechanical ventilation.

Informing the management of the post-COVID condition: insights from the Western Australian experience comparing those who tested positive and negative to early COVID-19 strains.

ObjectiveThis study aimed to compare the relative physical recovery and symptoms after SARS-CoV-2 infection between groups confirmed positive or negative to early strains of COVID-19.MethodsA prospective, longitudinal cohort study compared outcomes of metropolitan adults polymerase chain reaction-tested for COVID-19 between March and November 2020 in Western Australia. Control matching was attempted: inpatients (gender, age) and ambulatory clinic (gender, age, asthma, chronic pulmonary disease). One-year follow-up involved three repeated measures: physical function (grip strength and 1-min sit-to-stand) and patient-reported outcomes (Fatigue Severity Scale, modified Medical Research Council dyspnoea scale and Euroqol-5D-5L).ResultsThree hundred and forty-four participants were recruited (154 COVID+, age 54±18years, 75 females [49%]); 190 COVID-, age 52±16years, 67 females [35%]) prior to national vaccination roll-out. No between-group differences in physical function measures were evident at any time point. Fatigue (OR 6.62, 95% CI 2.74-15.97) and dyspnoea (OR 2.21, 95% CI 1.14-4.30) were higher in the COVID+ group at second assessment (T2). On Euroqol-5D-5L, no between-group differences were evident in the physical function domains of self-care, mobility or usual activities at any time point. However, COVID+ participants were less likely to report an absence of anxiety or depression symptoms at T2 (OR 0.41, 95% CI 0.19-0.89).ConclusionsNeither statistical nor clinically meaningful differences in physical function were evident between COVID+ and COVID- participants to 12-months after acute illness. Symptoms of fatigue, dyspnoea, anxiety or depression were more prevalent in the COVID+ group til ~8months after illness with between-group differences no longer evident at 1 year.

Short- and long-term hospital and community exercise programmes for patients with chronic obstructive pulmonary disease.

OBJECTIVE: Pulmonary rehabilitation in patients with COPD has been shown to be beneficial but the optimal setting is not known. In the present study, the efficacy of a short-term community-based exercise programme was compared with a standard hospital outpatient programme. Additionally, the usefulness of community or home programmes in maintaining improvements in the longer term was studied. METHODOLOGY: Forty-three patients with moderate to severe COPD were randomized to one of the following three groups: a 3-month hospital programme then a 9 month home programme (Hospital/Home); a 3-month hospital programme then a 9-month community programme (Hospital/Community); or a 12-month community programme (Community/Community). The initial 3-month programme was analysed by comparing the Hospital group (Hospital/Home plus Hospital/Community) with the Community group (Community/Community). Six-minute walking distance (6MWD), quality of life (Guyatt chronic respiratory disease questionnaire, CRQ) and lung function were measured at 0, 3, 6 and 12 months and results were analysed using the Wilcoxon rank sum test. RESULTS: At 3 months, there was a significant improvement from baseline in 6MWD in the Hospital group (81.3 +/- 18.3 m, P < 0.05, anova) but not the Community group (14.4 +/- 28.5 m, not significant). The difference between the groups was not significant (P = 0.058). At 3 months, there was a significant improvement in quality of life in the Hospital group (CRQ +16.3 +/- 3.1, P < 0.01, anova) and in the Community group (CRQ +10.2 +/- 4.9, P < 0.05, anova) but the difference between the groups was not significant. Following the initial 3-month programme, the dropout rate was high overall (73% by 12 months), and therefore data from the maintenance programme could not be analysed. CONCLUSIONS: A 3-month community-based exercise programme for patients with COPD did not improve 6MWD. The long-term retention rates in the programmes were poor.
