A retrospective cohort study on the impact of vaccination among Covid-19 patients by Star Health and Allied Insurance unveiled the significant impacts of vaccination among individuals 45 years and above. The study concluded that there was a marked reduction in the total hospitalisation expenses by approximately 24 per cent, the Average Length of Stay (ALOS) by a mean of 2.1 days, ICU requirement by 66 per cent and a reduction of approximately 81 per cent in mortality among patients who had completed two doses of vaccination.
The study was conducted during the second wave (March & April 2021) and considered a sample size of 3,820 hospitalised patients. The cohort study revealed that the average cost of hospitalisation of the unvaccinated group was Rs 2.77 lakh while the vaccinated group recorded an average cost of Rs 2.1 lakh. The cost reduction was due to factors like reduced need of ICU requirement and reduction in the length of hospital stay from an average of seven days among unvaccinated to an average of 4.9 days for the vaccinated group.
“The beginning of 2021 saw a breakthrough in vaccine discovery against Covid-19 making it the fastest vaccine discovery to date. We aimed to measure and understand in exact terms the impact of Covid-19 vaccination in patients who contracted the illness 14 days after the second dose versus unvaccinated patients, thus making it unique research in its own right,” said S Prakash, Managing Director, Star Health and Allied Insurance.
The main purpose of this study was not only to understand the medical benefit but also the financial implications.
“Our study covered pan India data of the patients affected by Covid-19. The aim was to assess the medical and financial implications of vaccination. Our study concluded that the ones who had taken the vaccination had a clear advantage over the non-vaccinated as we witnessed a significant difference in parameters like a hospital stay, cost of treatment, and death due to infection,” said Madhumathi Ramakrishnan, Joint Vice President Star Health and Allied Insurance.
The cohort study surveyed customers of Star Health and Allied Insurance Company who were admitted for Covid-19 treatment in 1,104 hospitals across the country and found that the ALOS, need for ICU and reduction in costs holds for patients with comorbidities as well. While the need for ICU for patients with comorbidities fell from a whopping 9.4 per cent to 5 per cent amongst those vaccinated, the treatment cost also reduced by nearly 15 per cent.
“However, the study also revealed that over 57 per cent of patients among the unvaccinated group were hesitant to take the vaccine due to fear, ignorance, or more worryingly, social factors and disinterest! There is an urgent need to address this and we hope that through this study we will be able to highlight the benefits of the vaccine, educate and motivate the public to get vaccinated soon,” added Prakash.
The study noted that nearly 86 per cent of those surveyed had not taken the vaccination and amongst these 43 per cent did not have any valid reason for not taking the jab.
