The study compared patients with average copays of $14.38 for primary care and $22.05 for specialist visits with patients whose average copays were much lower: $8.33 and $11.38, respectively.
During six years of study, the number of outpatient visits rose more slowly for patients with higher copayments while their hospital admissions and days in the hospital rose significantly.
