Presentation summary

Introduction :
This study describes patterns of Korean Medicine (KM) procedures and National Health Insurance (NHI)-reimbursable herbal prescriptions among claims carrying sleep-disorder diagnoses in Korea during 2011–2020.

Methods :
A customized claims dataset from the Health Insurance Review & Assessment Service (HIRA) was analyzed with no wash-out period. The observation window was 2011-01-01 to 2020-12-31. Claims including KCD-7G47.* and/or F51.* were identified, and KM utilization was summarized at the diagnosis/claim level (notpatient-level). KM procedures comprised acupuncture, electrostimulation acupuncture, moxibustion, cupping, and transcutaneous infrared irradiation. KM prescriptions included all 56 NHI-reimbursable herbal preparations; the most frequently prescribed items are reported. Distributions were additionally summarized by sex, age, calendar month of care, Sasang constitution, and concomitant KM diagnoses. Analyses were descriptive only ; no Western-medicine co-management analyses and no regression models were undertaken.

Results :
Across 2011–2020, KM use accounted for 8,323,747 sleep-disorder claims, representing 9.65% of all sleep-disorder medical utilization. By sex (diagnosis counts), male: 2,257,536; female: 6,066,211. KM procedure counts (total 22,163,872) were distributed as follows: acupuncture 13,727,099 (61.9%), moxibustion 3,130,009(14.1%), transcutaneous infrared irradiation 2,425,317 (10.9%), electrostimulation acupuncture 1,476,321(6.7%), and cupping 1,405,126 (6.3%). For KM prescriptions, the most frequently prescribed reimbursable preparations were Gamisoyo-san, Gungha-tang, Yijin-tang, and Pyeongwi-san (descending order).Distributions by sleep-disorder categories (insomnia; sleep-related breathing disorders ; sleep-related movement disorders ; circadian rhythm sleep–wake disorders ; central disorders of hypersomnolence ; parasomnias), calendar month, Sasang constitution, and concomitant KM diagnoses are summarized in the poster.
