Safety and feasibility of physiotherapy in ICU-admitted severe COVID-19 patients: an observational study

Early physiotherapy management of patients with Covid-19 admitted to a university hospital in Norway (March 2020 to July 2021)

AIM

The aim of this retrospective observational study was to describe the scope of physiotherapy, the population and the physiotherapy management of Covid-19 patients referred to physiotherapy at a university hospital in the period from March 2020 to July 2021.

METHOD

A descriptive observational study with access to data from a quality register, which contains clinical data of all patients admitted with Covid-19 to a university hospital in Norway. Data was obtained from electronic data sheets, where daily parameters for physiotherapy treatment were registered.

RESULTS

In total, 729 Covid-19 patients were admitted during this period. Of these, 507 (69.6%) received treatment by a physiotherapist (3510 sessions). The physiotherapy treatments were performed on intensive care units (ICU) (50%), intermediate care units (11%) and general medical units (39%), respectively. Patients were mainly treated during the day (98.5%) and 21% of the sessions were given on weekends or holidays. Within the 3510 sessions, 9459 interventions were performed in total (one to seven interventions per session). The most common intervention provided was positioning (35.4%). The most common interventions in medical units and intermediate care units were training with a positive expiratory pressure device (17.3% and 15.9% respectively), and techniques for reducing work of breathing (13% and 15% respectively). The most common intervention in the ICUs was passive mobilization (21.3%), mostly in combination with positioning, manual techniques and/or airway clearance.

CONCLUSION

This study provides characteristics of, and experiences with early physiotherapy, in sequentially hospitalized patients at a university hospital in Norway.

Association of ventilator-free days with respiratory physiotherapy in critically ill patients with Coronavirus Disease 2019 (COVID-19) during the first pandemic wave. A propensity score-weighted analysis

Background

Respiratory physiotherapy is reported as safe and feasible in mechanically ventilated patients with severe Coronavirus Disease (COVID-19) admitted to Intensive Care Unit (ICU), but the short-term benefits remain unclear.

Methods

We performed a retrospective observational study in four ICUs in Northern Italy. All patients with COVID-19 admitted to ICU and under invasive mechanical ventilation (MV) between March 1^st and May 30^th, 2020, were enrolled into the study. Overlap weighting based on the propensity score was used to adjust for confounding in the comparison of patients who had or had not been treated by physiotherapists. The primary outcome was the number of days alive and ventilator-free (VFDs). The secondary outcomes were arterial partial pressure of oxygen (PaO₂)/fraction of inspired oxygen (FiO₂) ratio (P/F) at ICU discharge, ICU length of stay, ICU and hospital mortality, and survival at 90 days. The trial protocol was registered on clinicaltrials.gov (NCT 05067907).

Results

A total of 317 patients were included in the analysis. The median VFDs was 18 days [interquartile range (IQR) 10; 24] in patients performing physiotherapy and 21 days (IQR 0; 26) in the group without physiotherapy [incidence rate ratio (IRR) 0.86, 95% confidence interval (CI): 0.78; 0.95]. The chance of 0 VFDs was lower for patients treated by physiotherapists compared to those who were not [odds ratio (OR) = 0.36, 95% CI: 0.18–0.71]. Survival at 90 days was 96.0% in the physiotherapy group and 70.6% in patients not performing physiotherapy [hazard ratio (HR) = 0.14, 95% CI: 0.03–0.71]. Number of VFDs was not associated with body mass index (BMI), sex, or P/F at ICU admission for individuals with at least 1 day off the ventilator.

Conclusion

In patients with COVID-19 admitted to ICU during the first pandemic wave and treated by physiotherapists, the number of days alive and free from MV was lower compared to patients who did not perform respiratory physiotherapy. Survival at 90 days in the physiotherapy group was greater compared to no physiotherapy. These findings may be the starting point for further investigation in this setting.

Time to active sitting position: One-year findings from a temporary COVID-19 intensive care unit

Objective

To investigate the association between time to active sitting position and clinical features in people with COVID-19 admitted to intensive care unit (ICU) and referred to physiotherapists.

Method

Prospective study conducted in the largest temporary ICU in Lombardy (Italy) between April 2020 and June 2021. All individuals with COVID-19 who received physiotherapy were included. Multivariable Cox proportional hazard model was fitted to explore the statistical association between active sitting position and characteristics of patients referred to physiotherapists, also accounting for the different multidisciplinary teams responsible for patients.

Results

284 individuals over 478 (59.4%) had access to physiotherapy, which was performed for a median of 8 days, without difference between multidisciplinary teams (P = 0.446). The active sitting position was reached after a median of 18 (IQR: 10.0–32.0) days. Sex was the only characteristic associated with the time to active sitting position, with males showing a reduced hazard by a factor of 0.65 (95% CI: 0.48–0.87; P = 0.0042) compared to females. At ICU discharge, nearly 50% individuals increased Manchester Mobility Score by 3 points. During physiotherapy no major adverse event was recorded.

Conclusion

Individuals with COVID-19 take long time to reach active sitting position in ICU, with males requiring longer rehabilitation than females.
