Abstract

BACKGROUND:

Calcium is prescribed worldwide for patients diagnosed with osteoporosis. However, the national utilization of calcium and compliance with calcium is unclear in Korea. Our purpose is to evaluate Korea's national utilization of calcium and compliance with calcium in patients with osteoporotic hip fracture from 2007 to 2010 using data from the Health Insurance Review and Assessment (HIRA) Service.

METHODS:

From 2007 to 2011, osteoporotic hip fractures were identified using the International Classification of Diseases, 10th revision (ICD-10) and procedure code form from the nationwide database of the Health Insurance Review and Assessment Service. Compliant users of calcium were defined as the patients' medication possession ratio of 80 or more. We analyzed the compliance of calcium according to age and gender.

RESULTS:

Among 85,228 patients with hip fracture, 20,800 patients (24.4%) received a prescription of a calcium supplement. Among them, only 1,692 patients (8.1%) were identified as compliant users of calcium. The proportion of compliant users was higher in women than men in all age groups. The proportion of compliant users decreased with age in women.

CONCLUSIONS:

In Korea, the national utilization of calcium was low and compliance with calcium was unsatisfactory even in patients with osteoporotic hip fracture.
