Trends in Incidence and Treatment of Herniated Lumbar Disc in Republic of Korea : A Nationwide Database Study

Trends of Korean medicine service utilization for lumbar disc herniation and spinal stenosis: A 10-year analysis of the 2010 to 2019 data

This retrospective, cross-sectional, and descriptive study aimed to analyze the trend of utilizing traditional Korean medicine services in patients with lumbar disc herniation (LDH) and/or lumbar spinal stenosis (LSS). In this study, based on the national patient sample data provided by Health Insurance Review and Assessment Service (HIRA), the trend of Korean medicine service utilization was investigated, including the following information: demographic characteristics of the patients, the total expenditure, number of claim statements per category, medical care expenditure per category, and routes of visiting traditional Korean medicine institutions. The study population comprised patients who visited Korean medicine institutions at least once from January 2010 to December 2019, with LSS and LDH as the primary diagnosis. LDH patients who used traditional Korean medicine services for treatment increased by about 1.36 times. LDH and LSS patients under 45 years of age were more likely to be males, but women accounted for a higher percentage among those over 45 years of age. Overall, women accounted for a slightly higher percentage than their counterparts for both diseases. From details of treatments received that were extracted from the claims data, acupuncture treatment accounted for the highest percentage for both disorders. Moreover, 50.7% of the patients who visited Korean medicine institutions to treat the two diseases also visited conventional Western medicine institutions. These patients, who were diagnosed with their condition at a Korean medicine institution, visited a conventional institution and then returned; the conventional institutions were primarily used for examination (40.5%). Increased utilization of traditional Korean medicine services was confirmed among patients with LDH and/or LSS; in particular, a sharp increase was noted among patients with LSS. The results of this study will be useful as basic research data for clinicians, researchers, and policy makers.

The assessment of the validity, safety, and utility of ChatGPT for patients with herniated lumbar disc: A preliminary study

ChatGPT is perceived as a potential tool for patients diagnosed with herniated lumbar disc (HLD) to ask questions concerning desired information, with provision for necessary responses. In this preliminary study, we assessed the validity, safety, and utility of ChatGPT in patients with HLD. Two physicians specializing in the treatment of musculoskeletal disorders discussed and determined the 12 most frequently asked questions by patients with HLD in clinical practice. We used ChatGPT (version 4.0) to ask questions related to HLD. Each question was inputted into ChatGPT, and the responses were assessed by the 2 physicians. A Likert score was used to evaluate the validity, safety, and utility of the responses generated by ChatGPT. Each score for validity, safety, and utility was divided into 4 points, with a score of 4 indicating the most valid, safe, and useful answers and 1 point indicating the worst answers. Regarding validity, ChatGPT responses demonstrated 4 points for 9 questions (9/12, 75.0%) and 3 points for 3 questions (3/12, 25.0%). Regarding safety, ChatGPT scored 4 points for 11 questions (11/12, 91.7%) and 3 points for 1 question (1/12, 8.3%). Regarding utility, ChatGPT responses exhibited 4 points for 9 questions (9/12, 75.0%) and 3 points for 3 questions (3/12, 25.0%). ChatGPT demonstrates a tendency to offer relatively valid, safe, and useful information regarding HLD. However, users should exercise caution as ChatGPT may occasionally provide incomplete answers to some questions on HLD.

A study on the 10-year trend of surgeries performed for lumbar disc herniation and comparative analysis of prescribed opioid analgesics and hospitalization duration: 2010-2019 HIRA NPS Data

BACKGROUND

This study, utilizing the claims data from the Health Insurance Review and Assessment Service of Korea, aimed to examine the 10-year (2010-2019) trends in various types of lumbar spine surgeries performed on patients diagnosed with lumbar herniated intervertebral disc (HIVD), and the current status of opioid prescriptions, as well as the duration of postoperative hospital stays based on the type of surgery performed.

METHOD

This retrospective cross-sectional study examined patients with one or more national health insurance claims carrying a primary or secondary diagnosis of HIVD (ICD-10 codes: M511, M518, M519) over a 10-year period (2010-2019). From the patients undergoing lumbar spine surgery, we selected those who did not require reoperation within 30 days following the initial lumbar surgery. Our final study sample comprised patients who underwent only one type of surgery.

RESULTS

Among the patients diagnosed with HIVD and subsequently undergoing lumbar surgery between 2010 and 2019, a slight downward trend was observed in those undergoing open discectomy (OD); however, OD persistently accounted for the highest proportion over the 10 years. Percutaneous endoscopic lumbar discectomy (PELD) demonstrated a consistent upward trend from 2016 to 2018. When inspecting trends, we noted a consistent escalation over the decade in the postoperative opioid prescription rates of strong opioids (50.7% in 2010 to 77.8% in 2019) and tramadol (50.9% in 2010 to 76.8% in 2019). Analyzing these trends by surgery type, spinal fusion exhibited a slightly higher rate of opioid prescriptions than other lumbar surgeries. Regarding the length of postoperative hospital stays, patients undergoing PELD recorded the shortest stay (7.04 ± 6.78 days), while spinal fusion necessitated the longest (20.14 ± 12.18 days).

CONCLUSION

This study analyzed the trends in types of lumbar spine surgeries, opioid analgesic prescriptions, and length of hospital stays over 10 years (2010-2019) among patients with HIVD in Korea. Our data and findings provide valuable evidence that may prove beneficial for clinicians and researchers involved in HIVD-related practices.

A spinal manipulative therapy altered brain activity in patients with lumbar disc herniation: A resting-state functional magnetic resonance imaging study

Purpose

Lumbar disc herniation (LDH) is one of the leading causes of low-back pain and results in a series of clinical symptoms, including pain, reflex loss, and muscle weakness. Spinal manipulative therapy (SMT) can relieve pain and promote internal and external stabilization of the lumbar spine. In this study, we investigated whether the brain alterations of LDH patients with SMT were frequency-dependent based on the calculation of Amplitude of Low-Frequency Fluctuations (ALFF) and fractional ALFF (fALFF). Further, we established a cohort of LDH patients to evaluate the contribution of SMT treatments to brain functional reorganization.

Methods

A total of 55 participants, including 27 LDH patients and 28 health controls (HCs), were collected. All LDH patients underwent two fMRI scans (before SMT and after the sixth SMT session). To represent LDH-related brain oscillatory activities, we calculated the ALFF and fALFF in the conventional band (0.01–0.08 Hz), the slow-4 band (0.027–0.073 Hz), and the slow-5 band (0.01–0.027 Hz). Moreover, we extracted ALFF and fALFF values in clusters with significant differences to evaluate the SMT effect.

Results

Compared with HCs, the LDH patients before SMT (LDH-pre) exhibited increased fALFF in right lingual gyri in the conventional band, and showed increased fALFF in left Cerebelum_Crus1 in the slow-4 band. We further examined the abnormal brain activities changes before and after the SMT intervention. The ALFF and fALFF values of LDH-pre group were higher than those of the HCs and LDH-pos groups. After SMT, the increased ALFF and fALFF values were suppressed for patients in conventional band and slow-4 band.

Conclusion

The present study characterized the altered regional patterns in spontaneous neural activity in patients with LDH. Meanwhile, SMT is an effective treatment of LDH, and we supposed that it might have been involved in modulating dysfunctional brain regions which are important for the processing of pain. The findings of the current study may provide new insights to understand pathological mechanism of LDH.

Association between pain and gait instability in patients with lumbar disc herniation

Objective

To determine whether pain is associated with gait instability in patients with lumbar disc herniation (LDH).

Methods

This retrospective cross-sectional study used data from electronic medical records. Among patients with lumbar back pain caused by LDH between January 2017 and July 2019, patients that underwent gait analysis were included. LDH was diagnosed using magnetic resonance imaging. An OptoGait photoelectric cell system was used for gait evaluation. Instability was measured using a gait symmetry index. Multivariate linear regression analysis was performed to determine the association between lumbar pain and gait instability.

Results

A total of 29 patients (12 females [41.4%] and 17 males [58.6%]; mean ± SD age, 40.6 ± 12.0 years) with LDH were enrolled in the study. With each 1-point increase in lumbar pain on the numeric rating scale, the symmetry index of the stance phase (0.33; 95% confidence interval [CI] 0.04, 0.62), swing phase (0.78; 95% CI 0.14, 1.43) and single support (0.79; 95% CI 0.15, 1.43) increased.

Conclusions

Gait instability in patients with LDH may occur due to an increase in pain.

Epidemiology of senile spinal diseases: a study based on the Health Insurance Review & Assessment Service database

According to the Statistics Korea in 2020, the elderly population aged 65 or older accounted for 15.7% of the total population, and by 2025 it will reach 20.3%, which will enter the super-aged society. In an aging society, many degenerative diseases occur with age. In particular, the spine is a structure that acts as a pillar of our body, and as we age, degenerative changes come. Representative senile spinal diseases include disc disease, spinal stenosis, spinal spondylolisthesis, scoliosis, kyphosis, and flat back syndrome. This study intends to examine the epidemiologic characteristics and trends of senile spinal diseases using Korean Health Insurance Review & Assessment Service database from 2010 to 2019. All of the senile spinal diseases have gradually increased in the number of patients and cost over the last 10 years. In addition, the proportion of those aged 60 and over increased among those diagnosed. And fusion surgery and discectomy also increased in the last 10 years, and the treatment cost and ratio of over 60 years old increased. Korea has already become an aging society. So, in the future, senile diseases will increase further, and among them, senile spinal diseases will steadily increase. As a result, the frequency and cost of surgery will continue to increase. Efforts are needed to understand this trend and to prevent senile spinal diseases. For example, regular exercise, proper posture and habits, adequate nutrition, and efforts such as quitting smoking should be required. When these efforts are made, more healthy old life will be achieved.

Risk Factors of Intervertebral Disc Pathology-A Point of View Formerly and Today-A Review

Intervertebral disc pathology is a common disorder that can be caused by genetic, mechanical, and behavioral factors; however, it is possible to slow its progression. Although environmental and behavioral factors were previously considered to be the sole causes of intervertebral disc pathologies such as disc herniation, recent studies have shown that genetic factors also play an important role. This review compares the perception of major risk factors from the last and present centuries. It also examines individual genetic and non-genetic factors acting as risk factors, as well as some approaches for preventing intervertebral disc pathologies, and compares available statistics regarding disc herniation.

A Prospective Observational Study of Return to Work after Single Level Lumbar Discectomy

OBJECTIVE

Lumbar disc herniation (LDH) is a common disease, and lumbar discectomy (LD) is a common neurosurgical procedure. However, there is little previous data on return to work (RTW) after LD. This study investigated the period until the RTW after LD prospectively. Clinically, the pain state at the time of RTW also checked. RTW failure rate 6 months after surgery also investigated.

METHODS

Patients with daily/regular jobs undergoing LD between September 2014 and December 2018 were enrolled. Pain was assessed by the Oswestri Disability Index (ODI) and the Numeric Rate Scale (NRS). Employment type was divided into self-employed, regular and contracted. Monthly telephone interviews were conducted to check RTW status and self-estimated work capability after surgery.

RESULTS

Sixty-seven patients enrolled in this study. Three patients failed to RTW, and three others resigned within 6 months after surgery. The preoperative NRS and ODI were 7.2±1.2 and 22.1±7.9, respectively. The average time to RTW was 5.1±6.0 weeks. At RTW, NRS was 1.5±1.8 and ODI was 6.3±3.9. Amongst patients that successfully returned to work were 16 self-employed workers, 42 regular employees, and three contracted workers. The time to RTW of self-employed, regular, and contracted workers were 5.9±8.8, 4.2±4.3 and 13.3±2.3 weeks, respectively (p=0.011). Thirty-six of the patients that returned to work self-reported a 22.8±15.6% reduction in work capability at 6 months.

CONCLUSION

RTW may vary depending on the employment status. In this study, we found that while employment type may affect the length to RTW, most patients were able to RTW and >40% of patients reported no loss of work capabilities 6 months postoperatively, hopefully alleviating some patient hesitation towards LD.
