The decline in patients has been largest for those awaiting planned treatments, but the number of people requiring immediate attention also dropped too, according to Statistics Norway figures.
Due to the coronavirus pandemic, hospitals had to prioritise differently in 2020 as a result of the increased need for intensive care units.
“2020 was a year marked by pandemics and restrictions. In many places hospitals have had to prioritise differently due to the coronavirus, and perhaps particularly as the result of the increased need for intensive care,” the report said.
This has contributed to a decrease in the number of patients in hospitals at all levels of care.
The number of patients with 24-hour stays decreased by 7 percent. The total number of days spent in hospital fell by 11 percent or 380,000 fewer days in a hospital bed in 2020 compared to 2019.
Hospital stays lasting at least 24 hours include both planned and unplanned visits. In 2020 planned visits accounted for 29 percent of all visits, which is a decrease of 16 percent from the previous year, while visits for immediate appointments decreased by 3 percent.

The figures show a decline for almost all diagnostic groups, but cancer patients had a smaller decline than other groups.
Planned treatment of various forms of cancer decreased by 8 percent, but acute help for tumours saw an increase of 11 percent.
This reverses a trend of numbers of patients in hospitals increasing year on year. The increases had primarily been driven by patients at outpatient clinics.
