Background

The rapid outbreak of coronavirus disease 2019 (COVID-19), a public health emergency of grave concern, warranted hospital admissions with almost 90,000 cases in June 2020 in city of Mumbai. 3-10% of the patients with moderate to severe involvement required intensive care unit (ICU) admission with respiratory support. Patients admitted in ICU with an acute COVID event present with respiratory dysfunction and are more likely to have critical illness myopathy and neuropathy (CIMN). Physiotherapy services being integral part of non-pharmacological management of any ICU was implemented for patients with COVID 19; a novel viral disease.

Objective

This retrospective study was undertaken to explore the physiotherapy practices that could be implemented in patients admitted with COVID 19 in the ICU and its effect on mobility and oxygen requirement as an outcome.

Methodology

Following ethical permission of institute, the data was extracted from electronic data record sheet in which daily parameters for physiotherapy intervention were recorded. Data from a single ICU and step down unit (SDU) from 5th June to 5th July 2020 was analysed. Records of patients diagnosed with COVID 19 and admitted in ICU or SDU were studied. Those in the age group of 18 to 90 years, of either gender were included. Demographic characteristics, disease severity, oxygen requirement, mobility status, physiotherapy intervention were studied.

Results

278 record sheets (110 ICU and 168 SDU) were retrospectively analysed for demographics. 44.55% of patients improved with side lying position, 37.27% with prone position and 10.91% with quarter prone position. 4.55% of patient maintained oxygenation in propped up sitting. 2.73% could not be positioned. Chest physiotherapy techniques applied were deep breathing, ACBT, paced breathing and diaphragmatic breathing. Deep intercostal pressure on NIV along with vibrations was given to 12.72% of patients in the ICU. Group therapy sessions were conducted in SDU where 50.59% patients participated. ICU mobility score showed significant improvement on Wilcoxon Signed Ranks test status on day 7 in the ICU (z=-5.99, p=0.00) and SDU (z= 7.676, p=0.00) compared to day 1. Descriptive analysis showed a definitive reduction in oxygen support requirement.

Conclusion

Most common form of physiotherapy interventions in patients with Covid 19 were therapeutic positioning, early mobilization and breathing exercises. Physiotherapy intervention appears promising in facilitating early patient ambulation and discharge. This study shows that it is safe and feasible to provide early physiotherapy treatment techniques in patients with COVID-19 using appropriate measures of infection prevention and cross contamination.
