Characteristics, therapeutic modalities and outcomes of COVID-19 ventilated patients in a tertiary care hospital in counter-insurgency zone: Our experience.

Background: Coronavirus disease 2019 (COVID-19) can result in severe life-threatening course requiring ventilatory support. This study highlights data pertaining to ventilated patients to enhance our understanding of COVID-19 as it evolves.

Methods: A descriptive, retrospective analysis was carried out on 50 COVID-19 RT-PCR positive patients who received mechanical ventilation at a tertiary care hospital in counter-insurgency (CI) zone, from June to December 2020. Data pertaining to patient characteristics, treatment, ventilator support and outcomes was analysed.

Results: Out of 50 patients, 74% were aged 50 years and above with 60% patients having comorbidities. 39 patients received non-invasive ventilation (NIV) and 04 patients received invasive mechanical ventilation (IMV) while 07 patients were converted from NIV to IMV during the hospital stay. Out of the 50 patients who received ventilator support 25 (50%) survived to discharge. The overall survival was 47.3% amongst the males while it was 58.3% for the females. The majority of survivors were in the NIV category (61.5%) while only 9.0% survived amongst those who received IMV. Average length of stay on NIV for patients was 5.3 days and for IMV was 7.5 days. All 50 patients received therapy in the form of steroids, anticoagulants, broad spectrum antibiotics and antivirals. Remdesivir was given to 40 of these patients out of which 20 survived (50%). Interleukin-6 therapy (Tocilizumab) was given to five patients of which four survived (80%).

Conclusion: This study helps us to gain insights into the outcomes of COVID-19 patients managed in a tertiary care hospital in CI zone.
