Healthcare usage and cost for plantar fasciitis: a retrospective observational analysis of the 2010-2018 health insurance review and assessment service national patient sample data.

BACKGROUND: 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. METHODS: 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. RESULTS: 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. CONCLUSION: 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.

Trends in healthcare utilisation of patients with migraine in South Korea: a retrospective observational study using Health Insurance Review and Assessment Service National Patient Sample data from 2010 to 2018.

OBJECTIVE: This study used 2010-2018 Health Insurance Review and Assessment Service National Patient Sample data to analyse the distribution and healthcare utilisation of patients with migraine in South Korea. DESIGN: Retrospective, observational study using serial cross-sectional data. PARTICIPANTS: Patients with primary diagnosis of G43, a Korean Standard Classification of Diseases-10 code for migraine, were included in the analysis. The exclusion criteria were missing code information; code for dental, health centre or psychiatry; institution type specified as nursing hospital, psychiatric hospital, dental hospital, midwifery centre or health centre; blank entries for total cost or days of care. 453 246 records of patients and 117 157 patients corresponding to those records were identified. OUTCOME MEASURES: Primary outcome measures were medical service utilisation status, treatment methods and drug use status associated with migraine. RESULTS: Cases and patients of migraine increased from 48 846 and 19 468 (2010) to 52 729 and 20 802 (2018), respectively, increases of 7.95% and 6.85%, respectively, compared with 2010. Total cost of care increased from $921 857.88 (2010) to $1 711 219.60 (2018). The most common age range of patients was 45-54 years, with 2.69 times more female than male patients. In Western medicine hospitals, subcutaneous or intramuscular injection therapy was used frequently, while in Korean medicine hospitals, acupuncture therapy was used. Among Western medicine outpatients, more than 50% of the therapeutics prescribed for acute migraine were simple analgesics or non-steroidal anti-inflammatory drugs. The number of prescriptions for the prevention of episodic migraine increased from 13 600 cases (2010) to 20 546 cases (2018), representing the steepest increase in drug utilisation. CONCLUSIONS: Treatments frequently used in Western and Korean medicine hospitals and their frequency of use and costs were identified. The findings of this study can be used as a basis for relevant health policy decisions.

Cost-Utility Analysis of Chuna Manual Therapy and Usual Care for Chronic Neck Pain: A Multicenter Pragmatic Randomized Controlled Trial.

This study aimed to compare the cost-effectiveness of manual therapy and usual care for patients with chronic neck pain. A cost-utility analysis alongside a pragmatic randomized controlled trial was conducted in five South Korean hospitals. Data were procured from surveys and nationally representative data. Participants were 108 patients aged between 19 and 60 years, with chronic neck pain persisting for at least 3 months and a pain intensity score of ≥5 on the numerical rating scale in the last 3 days. The study was conducted for 1 year, including 5 weeks of intervention and additional observational periods. Participants were divided into a manual therapy (Chuna) group and a usual care group, and quality-adjusted life-years, costs, and the incremental cost-effectiveness ratio were calculated. The quality-adjusted life-years of the manual therapy group were 0.024 higher than that of the usual care group. From the societal perspective, manual therapy incurred a lower cost-at $2,131-and was, therefore, the more cost-effective intervention. From a healthcare system perspective, the cost of manual therapy was higher, with an incremental cost-effectiveness ratio amount of $11,217. Manual therapy is more cost-effective for non-specific chronic neck pain management from both a healthcare system and societal perspective.

Analysis of Scoliosis-related Medical Services in South Korea Between 2010 and 2018: A Cross-sectional Study Using Health Insurance Review and Assessment Service Data.

STUDY DESIGN: Retrospective, cross-sectional study. OBJECTIVES: The aim of this study was to analyze types and cost of care for scoliosis and present health care utilization by patients to provide data on the standard treatment and cost for scoliosis in South Korea. SUMMARY OF BACKGROUND DATA: Scoliosis is defined as an abnormally laterally curved spine with a Cobb angle of ≥10°.Data are lacking on which treatments are popular for general scoliosis and which service categories incur the most cost in South Korea. METHODS: Data from the Health Insurance Review and Assessment Service-National Patient Sample were used. In total, 108,643 final cases and 32,362 patients in South Korea who received Western medicine care or Korean medicine care at least once with scoliosis (ICD-10 code M41) as the principal diagnosis during January 2010 to December 2018 comprised the study sample. We analyzed health care utilization according to certain factors (e.g., age, sex, payer type, type of visit, and medical institution), health care utilization by service category and service code, and medication prescriptions filled by private or hospital pharmacies. RESULTS: Patients aged 24 years or younger most frequently utilized health care services, with more female (64.84%) than male patients (35.16%). Most patients received only Western medicine care (92.18%), whereas 6.56% only received Korean medicine care. Most cases (99.37%) corresponded to outpatient. Regarding service category, treatment and surgery, examination, special equipment and radiologic diagnosis accounted for a substantial percentage. Regarding service code, cost of examination, imaging, and physiotherapy comprised a high percentage of Western medicine, whereas cost of examination, acupuncture, and cupping therapy accounted for a high percentage of Korean medicine. The most commonly prescribed medications for scoliosis in pharmacies were anti-inflammatory analgesics (nonsteroidal anti-inflammatory drugs), antacids, and skeletal muscle relaxers. CONCLUSION: The findings can be used as foundational data for experts such as health care policymakers, clinicians, and researchers.Level of Evidence: 4.

Analysis of outpatient expenditure trends using Korean Health Panel Survey data of patients diagnosed with lumbar intervertebral disc herniation.

OBJECTIVE: In this study, we aimed to analyze cost trends for the outpatient treatment of lumbar intervertebral disc herniation (LDH). METHODS: We used cross-sectional data obtained from the Korea Health Panel Survey from 2011 to 2015. We compared outpatient medical expenses for conservative treatment of LDH using traditional Korean medicine (TKM) or Western medicine (WM). RESULTS: This analysis revealed that the total medical expenses for outpatient treatment of LDH using WM treatment methods increased by 30% from 2011 to 2015, and self-payment expenses increased by 50%. The total medical expenses for outpatient treatment of LDH using TKM methods increased by 8%, and self-payment expenses decreased by 33%. The National Health Insurance Service (NHIS) expenditure for WM increased by 7%, and non-covered costs increased by 83%. The NHIS expenditure for TKM increased by 41%, and non-covered costs decreased by 66%. CONCLUSIONS: The total medical expenses for WM treatments are increasing in Korea, especially for non-covered treatments. The non-covered costs for TKM treatments are decreasing, suggesting a change in medical cost trends according to whether Korea's actual medical expense insurance scheme is applied.

Effectiveness and cost-effectiveness of acupuncture with Doin therapy for chronic neck pain: a study protocol for a multicentre, randomised controlled clinical trial.

INTRODUCTION: Doin therapy is a manual therapy used in Korean rehabilitation medicine. Recently, the use of acupuncture with Doin has increased in clinics and clinical trials have demonstrated its effects. However, well-designed studies examining the efficacy and cost-effectiveness of acupuncture with Doin therapy are rare. METHODS AND ANALYSIS: This multicentre, assessor-blinded, randomised controlled trial with two parallel groups aims to evaluate the clinical effects and cost-effectiveness of acupuncture with Doin therapy. A total of 124 patients (with a neck pain duration of 6 months or longer and a Numeric Rating Scale ≥5) will be recruited at five Korean medicine hospitals. Patients will be randomly allocated to acupuncture with Doin therapy (n=62) and acupuncture alone (n=62) for 5 weeks of treatment. This study will be carried out with outcome assessor and statistician blinding. The primary outcome measure will consist of improvement in neck pain using the Visual Analogue Scale at 6 weeks. The secondary outcomes including measures of pain, functional disability, health-related quality of life and economic evaluation will be conducted at 6 weeks, and 3, 6, 9 and 12 months after treatment ETHICS AND DISSEMINATION: The project is approved by the Institutional Review Board (IRB) of the Jaseng Hospital of Korean Medicine and the Kyung Hee University Korean Medicine Hospital at Gangdong. Dissemination will occur after the findings from this study are published in other peer reviewed journals. TRIAL REGISTRATION NUMBERS: NCT03558178; KCT0003068; Pre-results.
