The Stockholm region, together with other regions, has received criticism from the Swedish Health and Care Inspectorate (Ivo) for having mismanaged the care of covid patients in nursing homes.
During the period March-August last year, 1,089 people over the age of 70 died in special housing (Säbo) in Stockholm where covid was found.
A separate review by the region on deaths on Säbo shows that in 17 percent of the cases, covid-19 was the main cause of death.
For the vast majority, 75 percent, it is pointed out that the infection contributed to the person's death.
Factors such as age, fragility and morbidity have played a role.
In other cases, 8 percent, it is estimated that another illness caused the person to die.
A total of 228 journals have been reviewed.
However, the region says that no definite general conclusions can be drawn yet, as there are shortcomings in, for example, journal entries.
"Care at special housing for the elderly has been debated and now there is a broader analysis and basis for measures," says chief physician Johan Bratt in a press release.
Similar reviews of deaths have been made in Östergötland, among other places.
It was found that in 15 per cent of the cases examined, covid-19 was judged to have been the direct cause of death, in 70 per cent it contributed to the person's death and for 15 per cent other diseases were judged to be the cause of death.
