Plantar fasciitis (PF) is the most common cause of heel pain in adults, and the number of patients and medical expenses are increasing annually. However, studies on this condition are lacking. There is a need to investigate universally administered PF treatment and the associated costs. Therefore we analyzed the South Korean Health Insurance Review and Assessment Service data to investigate the distribution and healthcare usage of patients with PF. A cross-sectional retrospective observational design was used in this study. Patients diagnosed with PF (ICD-10 code M72.2) between January 2010 and December 2018 in South Korea, of whom 60,079 had used healthcare at least once, were included in the study. We assessed healthcare usage and cost due to PF, treatment method, and visit route. All statistical analyses were performed with descriptive statistics using SAS 9.4 version. The number of treated cases of PF and patients with PF was 11,627 cases and 3,571 patients in 2010, respectively, which increased annually to 38,515 cases and 10,125 patients by 2018, respectively. The 45-54-year-old age group had the highest number of patients; the patient population was predominantly women. Physical therapy was used frequently in Western medicine (WM) institutions, where > 50% of the medicines prescribed to outpatients were analgesics. In contrast, acupuncture therapy was most commonly used in Korean medicine (KM) institutions. A high percentage of patients who visited a KM institution, followed by a WM institution, and then returned to the same KM institution had visited the WM institution for radiological diagnostic examination. This study analyzed nine years of period data from a patient sample of claims data from the Health Insurance Review and Assessment Service to examine the current status of health service use for PF in Korea. We obtained information on the status of WM/KM institution visits for PF treatment, which could be useful for health policymakers. Study findings regarding treatments often used in WM/KM, the frequency of treatments, and their costs could be used as basic data by clinicians and researchers.
