Oxycodone and Morphine Use in Hospitals and Primary Care in Norway 2010–2021: A Nationwide Study

This study is the first to provide quantitative evidence of covariation between in-hospital use and primary care opioid prescribing across a national healthcare system. Despite recommendations favoring morphine, oxycodone prescribing continues to rise in Norway, with marked geographical variation. By linking procurement data, prescription patterns and tender agreements, our findings highlight the need to consider hospital practices and structural factors when addressing opioid prescribing. These results offer new insights into potential levers for opioid stewardship across care levels.
