According to the study, which analyzed the period between 1 March and 22 April, the number of deaths registered in Portugal can reach a value that represents almost five times more than those attributed to covid-19, which on 27 April set at 928, according to official figures.

The authors of the study, specialists from the Institute of Preventive Medicine and Public Health and the Institute of Health Based on Evidence, from the Faculty of Medicine of the University of Lisbon, recall that the excess mortality in March and April “cannot be compared with February , not even with the same years, but it should first refer to the holiday months”, in which there is a reduction in activity and circulation of people and, therefore, a decrease in mortality due to road accidents.

“The state of emergency that Portugal has been in has led to several restrictive measures with an impact, for example, in reducing mortality from road or work accidents and also in a drop in the number of other infections characteristic of this time of year or heights less social isolation, which should be discounted from the results analyzed”, considers António Vaz Carneiro, one of the authors.

For Vaz Carneiro, "the number of deaths most identified is even greater than previously thought, by not considering this fall in deaths on the road or at work".

The data now released are higher than those estimated last week on the Covid-19 Barometer, from the National School of Public Health, which showed an excess mortality of 1,255 deaths, but only for the period between 16 March and 14 April.

Faced with this data from the ENSP last week, the Director-General of Health, Graça Freitas, said that considering the period from the beginning of the year until 21 April, the excess mortality was due to 439 deaths in relation to the average of the same period in previous five years.

For the work now published in Ata Médica, the scientific journal of the Ordem dos Médicos, the authors used public databases to estimate the excess mortality by age and region, between 1 March and 22 April, proposing levels adjusted to the current state of emergency period. The conclusions point to an excess of mortality between 2,400 and 4,000 deaths.

As in the ENSP study, this study indicates that excess mortality is mainly associated with older age groups (age over 65 years). The absolute numbers indicate more deaths in the districts of Aveiro, Porto and Lisbon, which is in line with the areas with the most patients diagnosed with covid-19 and also with the highest population density.

"If the analysis of the numbers is done in relative terms, there are no significant regional differences, although there is a tendency for a greater excess of mortality in the older districts", they stress.

The study also advances some worrying figures that may justify these deaths in excess: between 1 March and 22 April, there were 191,666 fewer patients with red bracelets in hospitals, 30,159 less with orange bracelets and 160,736 less with yellow bracelets.

With reference to mortality in the 24 to 48 hours after admission to hospitals before the pandemic, “these breaks correspond to a potential of at least 1,291 deaths, 79 in patients screened with a red bracelet, 1,206 with an orange bracelet and 6 with a yellow bracelet”, is indicated.

In a comment to this study, the president of the Ordem dos Médicos reminds us of the urgency of creating “a ‘task-force’ that works in an articulated way and that quickly looks at this data to be able to redesign the response” to patients.

Regarding the causes, the data suggest a tripartite explanation for the excess of mortality: deaths by covid-19 identified by the authorities, deaths by covid-19 but not identified and reduced access to health care.

In this study, the number of excess non-covid deaths was four to five higher than the deaths attributed to the disease caused by the new coronavirus.

“For any immediate future plan of the National Health Service, we must move from risk management of covid infection, to global risk management (covid and non-covid) to avoid this dramatic excess of mortality”, considers António Vaz Carneiro.
