DIAGNOSIS 61,49 60,9 62,12 38,93 38,11 39,73 Notas: In each of the groups, only those diagnoses that are considered major will be incorporated. 2) When comparing the information on hospital morbidity for covid-19 infection and respiratory diseases with the previous year, we should note that the in February 2020, the World Health Organisation (WHO) established an emergency code in the International Classification of Diseases (ICD-10) for the coding of covid-19 infections. This code was implemented in the ICD-10-CM (the classification used in the coding of diagnoses in hospitalized patients), on an exceptional basis, as of April 1, 2020 by the Centre for Disease Control and Prevention of the National Centre for Health Statistics (CDC/NCHS). Given the health crisis taking place at the time in Spain, it was decided not to implement the new code until there was a decrease in pressure on health systems, so that information systems could better adjust to the change. Finally, the new code U07.1 for COVID-19 infection was implemented by hospitals starting in July 2020. 3) The coefficients of variation shown in this table are population groups, see methodology. Given the characteristics of the group P00-P96, corresponding to group 'Certain diseases originating in the perinatal period ', I do not know facilitates the coefficient of population variation for these diagnoses because your calculation is not representative when the average age is expressed in years and so close to zero.
