Description
Jan Porthun and four co-authors track how often CT scans of the sinuses are performed in Norway, and how rates vary by region, age, and sex. Sinus CT is a standard diagnostic tool, yet it rarely changes management and is often classed as low-value care. Their 2026 study uses administrative data for all outpatient sinus CT in Norway from 2013 to 2023. Rates were adjusted for age and sex so regions could be compared fairly.
The adjusted rate fell from 52 to 46 scans per 10,000 people over the decade. At the same time, the gap between high-use and low-use regions grew wider on every variation measure. Women were scanned about 1.42 times as often as men. The team links part of the decline to the coronavirus pandemic and to a choosing-wisely campaign against low-value care. Wide gaps hint that many scans, above all in women, may add little.
