ABSTRACTObjectivesThe routine screening for macroprolactin of all hyperprolactinemic patients may avoid unnecessary imaging procedures and medication prescription. The study described the frequency and types of tests requested after a diagnosis of high serum prolactin concentration, and assessed whether the diagnosis of macroprolactinemia resulted in lower downstream utilization and costs compared with hyperprolactinemic patients.MethodsA cost analysis was conducted using a decision tree to model the health-care utilization of the two groups. The database of the Fleury Medicina e Saúde provided the tests and medication of patients with a prolactin value ≥30 µg/L for a period of 6 months.ResultsSix hundred fifty-four of 1793 patients (36.5%) had hyperprolactinemia because of macroprolactin. The average number of tests per individual was higher (P = 0.001) in the patients with true hyperprolactinemia (3.07) than in patients with macroprolactinemia (2.51). The average cost in the hyperprolactinemic group (R$425 or €162) was significantly higher (P < 0.001) than the macroprolactinemic group (R$340 or €130), an incremental cost 25% higher.ConclusionThe macroprolactin screening did not completely avoid inappropriate clinical investigation or associated health-care costs. Our results demonstrate the importance of proper medical education and knowledge diffusion of the meaning of macroprolactinemia.
