Recently, one of the most awaited publications by the premier government medical institute of our country, titled “Clinicoepidemiological Features and Mortality Analysis of Deceased Patients with COVID-19 in a Tertiary Care Center”, was a very delightful read.1 All the intensivists of India look up to this institute for regular guidelines of management of COVID-19. It is a very informative and learning piece analyzing mortality among the patients admitted to one of the (intensive care units) ICU of this center.
When compared with other similar studies across the globe, this paper does not provide supplementary data that could have answered questions like how many of the admitted patients were intubated in total and what was the mortality rate among the subgroup who were intubated.2,3 Rather a retrospective approach of data representation has been employed, which tells that among the total 247 deceased patients, 24.2% were intubated and 30.3% of total deceased were intubated within 24 hours. Even this representation does not throw light on how many patients of total 654 patients were intubated during their ICU stay. The policy guiding intubation of patients should also be specified as if it was decided by the intensivist on duty or by any fixed institutional criteria.
The incidence of pulmonary embolism (PE) among the deceased in the original paper is 2.8%, which is quite less than reported by Mahmoud et al. in a meta-analysis who reported the overall PE rate in ICU to be 19%, and on autopsy, 22% of deceased patients were found to have PE in COVID-19.4 The question that remains unanswered is how were those patients, who died in this published paper, diagnosed with PE. The diagnosis of PE was a clinical diagnosis or radiological diagnosis or by autopsy should have been specified. If the incidence of PE is so less than what was the antithrombotic practice of the institute as this piece of information can help to save many lives.
