Reliability of Standardized Protocol of Ultrasound of the Lungs in Prediction of Severity of Covid-19 Infection
Study Details
Study Description
Brief Summary
Ultrasound can reliably detect morphologic changes associated with pneumonia. Additionally, protocols were elaborated which unify the investigation procedure and improve the intra- and interrater reliability. Moreover, ultrasound is a time and cost-effective and widely available method. The aim of this study is to evaluate the efficacy of the ultrasound of the lungs in predicting the length of hospitalization, of intensive care and of mechanical ventilation in Covid-19 pneumonia. Further aims are the evaluation of the efficacy of the ultrasound of the lungs in predicting the risk of death and of long-term pulmonary complications as consequences of Covid-19 pneumonia.

Detailed Description
Covid-19 pneumonia became the worldwide, serious health problem, affecting nearly 20 million people and causing nearly one million deaths. The health systems of many countries are overwhelmed with the increased need of medical care, of the number of available hospital beds, intensive care beds and ventilators. The proper management of available resources becomes now critical. Ultrasound can reliably detect morphologic changes associated with pneumonia, especially in Covid-19 pneumonia, where the involvement of superficial parts of the lungs predominates. Additionally, protocols were elaborated which unify the investigation procedure and improve the intra- and interrater reliability. Moreover, ultrasound is a time and cost-effective and widely available method. Finally, it is much easier to take measures, which minimize the risk of viral transmission between patients for ultrasound equipment than for other lung imaging devices such as x-ray or computer tomography. The aim of this study is to evaluate the efficacy of the ultrasound of the lungs in predicting the length of hospitalization, of intensive care and of mechanical ventilation in Covid-19 pneumonia. Further aims are the evaluation of the efficacy of the ultrasound of the lungs in predicting the risk of death and of the long-term pulmonary complications as consequences of Covid-19 pneumonia. The study will include repeated ultrasound investigations in severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) positive patients admitted to the University Hospital in Cracow (Poland) performed during hospitalization and after discharge. The relation of severity and the course of pneumonia revealed by ultrasound to clinical condition, long term complications, use of mechanical ventilation, admission to intensive care and results of laboratory tests will be examined.
Study Design
Arms and Interventions
| Arm | Intervention/Treatment |
|---|---|
| Changes in the lungs on admission Patients with Covid-19 infection admitted to the University Hospital with changes in the ultrasound on admission, suggesting pneumonia. |
|
| No changes in the lungs on admission Patients with Covid-19 infection admitted to the University Hospital without changes in the ultrasound on admission, suggesting pneumonia. |
Outcome Measures
Primary Outcome Measures
- Relation of changes in ultrasound and progression to respiratory failure [Through study completion, an average of 1 year.]
Comparison of percentage of patients with oxygenation index drop below 300 mmHg during 14 after inclusion between group with and without changes in the ultrasound on admission.
- Impact of ultrasonographic pneumonia signs on the day of admission on severity of COVID-19 infection [Through study completion, an average of 1 year.]
Comparison of frequency of intensive care, ventilator use and of the number of days of hospital stay, between group with signs of pneumonia vs. group without signs of pneumonia in the ultrasound, on the day of admission.
Secondary Outcome Measures
- Sensitivity of ultrasonographic pneumonia signs in detecting respiratory failure [Through study completion, an average of 1 year.]
Correlation of the score reflecting severity of ultrasonographic pneumonia signs with oxygen saturation of arterial blood and with oxygen and carbon dioxide partial pressure in repetitive measurements.
- Sensitivity of ultrasound in detecting interstitial changes in the lungs [Through study completion, an average of 1 year.]
Correlation of the score reflecting severity of ultrasonographic pneumonia signs with the volume of lung interstitium affected by pneumonia, measured in high resolution computer tomography scans.
- Impact change in severity of ultrasonographic pneumonia signs on severity of COVID-19 infection [Through study completion, an average of 1 year.]
Comparison of frequency of intensive care, ventilator use and of the number of days of hospital stay, between group which improved and which did not improve in the score reflecting severity of ultrasonographic pneumonia signs from the measurement on the day of admission to measurement five days later.
