Finohta's health technology assessment report on bariatric surgery included a cost-utility analysis on three main surgical interventions used in Finland. A cost-utility analysis from the health care provider's perspective with a ten year time horizon was conducted. The parameter values were based on a representative population survey, register data, literature and expert opinions. Based on the analysis, bariatric surgery is more effective and less costly than current prevailing forms of treatment for the morbidly obese in Finland. The results were robust and consistent with previously published studies: Bariatric surgery is cost-effective in treatment of morbid obesity.
Data about the implementation of long-term follow-up of weight loss operation patients and their nutritional status has been lacking in Finland.
We examined the postoperative complications and long-term outcome in respect of weight control, symptoms, nutritional status and medication of 173 patients having undergone gastric bypass. The data were collected from patient records and by questionnaires.
Postoperative complications and weight loss were at the international level. The number of those using antidiabetic and antihypertensive drugs decreased.
The results are in agreement with the international level, but follow-up treatment requires attention in Finland.
