A strict gluten-free diet (GFD) can be diversified by non-contaminated oats, but there is a shortage of long-term studies concerning its safety. We compared long-term treatment outcomes and factors associated with the introduction of oats between celiac patients on a GFD with or without oats. Eight hundred sixty-nine previously diagnosed celiac patients were interviewed. The validated Gastrointestinal Symptom Rating Scale (GSRS), Psychological General Well-Being (PGWB), and Short-Form 36 Health Survey (SF-36) questionnaires were used to assess symptoms and quality of life, serological tests were performed, and results of histology were confirmed from patient records. We found the median duration of GFD to be 10 years and 82% using oats. Factors predicting the consumption of oats were diagnosis after the year 2000, advice from a dietitian, detection by screening, and mild clinical presentation. Oat consumers and non-consumers did not differ in dietary adherence (96.5% vs. 97.4%, p = 0.746), the prevalence of symptoms (22.9% vs. 22.5%, p = 0.931), positivity for endomysial antibodies (8.8% vs. 6.0%, p = 0.237), histological recovery after one year (63.1% vs. 60.0%, p = 0.773), malignancy (4.8% vs. 3.3%, p = 0.420), osteoporosis/osteopenia (9.2% vs. 11.0%, p = 0.489), or fractures (26.9% vs. 27.9%, p = 0.791). The oat consumers had better SF-36 physical role limitations and general health scores. Based on our results, the long-term consumption of oats in celiac disease patients is safe and may improve quality of life.

The single-payer systems examined differ in the number and age of licensed and subsidized entities, along with access to innovative entities. The NHS subsidized the most entities, the newest entities and the most innovative entities. NZ's PHARMAC system subsidized the fewest and oldest entities, and the fewest innovative entities. The VANF and PBS consistently fell between the other two systems in terms of the number of subsidized entities, age of subsidized entities and number of subsidized innovative entities.

In New Zealand, medicines are heavily subsidized across therapy groups, but those uniquely subsidized were older entities. In Finland, more "newer" medicines are subsidized and available, but the level and coverage of subsidy is lower and thus, the patient cost burden is higher. The cost containment policies adopted seem to affect patients' access to medicines mainly by availability in New Zealand and by affordability in Finland.
