Sick Leave and Productivity

At the empirically observed 30–50% remission rate, projected 26-week sick leave savings range from €207,652 to €346,086 per 100 patients. Potential sick leave savings are substantially larger than healthcare savings, particularly under the 26-week sick leave duration scenario. A conservative estimate based on a mean reduction of 1.5 working days yields a modest but real saving of €444 per participant. Norway's tax-funded healthcare system means insomnia-related excess hospital use and productivity loss translate directly into public expenditure. CHD patients with insomnia were almost four times more likely to be on sick leave at baseline than those without insomnia (23% vs 6%; RR = 3.90).
