Nearly 42 lakh people lose their lives every year in the world after 30 days of surgery. This number is higher than those died by HIV, TB and malaria (29.70 Lakh). A study published in The Lancet Journal states that half of the deaths due to surgery occur in lower and middle income countries.
According to researchers from the University of Birmingham in the UK, if the operation was made available to all patients who need it, the number of such deaths would increase to 61 lakh. According to researchers, there are 313 crore surgeries worldwide, but there is very little information about its quality at the moment.
