Trend in the Incidence of Severe Partial Edentulism among Adults Using the Korean National Health Insurance Service Claim Data, 2014-2018.

PURPOSE: Missing teeth is one of the most important indicators of oral health behavior and the result of dental caries, periodontal disease, and injuries. This study examined a trend in the incidence of severe partial edentulism (SPE) using the Korean National Health Insurance Service (KNHIS) data. MATERIALS AND METHODS: Data of adults aged ≥20 years were obtained from the KNHIS for the 2014-2018 period. SPE was defined in dental information within a population with a treatment history of dental scaling as having 1 to 8 natural teeth. Crude incidence rates (CIRs) and age-standardized incidence rates (AIRs) with 95% confidence interval were calculated per 100000 persons. The Cochran Armitage trend (CAT) test and average annual percentage change were used to analyze SPE trends. RESULTS: The CIRs among Korean adults were from 346.29 to 391.11 in 2014-2016 and from 391.11 to 354.09 in 2016-2018. The AIRs trend statistically increased by 4.31% from 346.29 to 376.80 and decreased by 4.72% from 376.80 to 342.10. The AIRs in men increased by 4.00% and decreased by 3.01%. The AIRs in women decreased by 2.18% and increased by 2.11% (CAT; p<0.01). The AIRs by region and income also showed trends of increase and decrease. CONCLUSION: The study showed that the incidence trend of SPE increased and decreased from 2014 to 2018. This result would be able to aid in the planning of public oral health, and may also serve as fundamental data for verifying the impact of the public oral health policies implemented.

Venous Thromboembolism Following Hip and Knee Replacement Arthroplasty in Korea: A Nationwide Study Based on Claims Registry.

The aim of this study was to examine the incidence and trends of clinically relevant venous thromboembolism (VTE) including deep vein thrombosis (DVT) and pulmonary embolism (PE) after hip and knee replacement arthroplasty (HKRA) in Korea. Between January 1 and December 31, 2010, 22,127 hip replacement arthroplasty (HRA) patients and 52,882 knee replacement arthroplasty (KRA) patients were enrolled in the analysis using the administrative claims database of the Health Insurance Review and Assessment Service (HIRA). All available parameters including procedure history and clinically relevant VTE during the 90 days after HKRA were identified based on diagnostic and electronic data interchange (EDI) codes. The overall incidence of VTE, DVT, and PE during the 90 days was 3.9% (n=853), 2.7% (n=597), and 1.5% (n=327) after HRA, while the incidence was 3.8% (n=1,990), 3.2% (n=1,699), and 0.7% (n=355) after KRA. The incidence of VTE after HKRA was significantly higher in patients who had previous VTE history (odds ratio [OR], 10.8 after HRA, OR, 8.5 after KRA), chronic heart failure (2.1, 1.3), arrhythmia (1.8, 1.7), and atrial fibrillation (3.4, 2.1) than in patients who did not. The VTE incidence in patients with chemoprophylaxis was higher than that in patients without chemoprophylaxis. The incidence of VTEs revealed in this retrospective review was not low compared with the results of the studies targeting other Asian or Caucasian populations. It may warrant routine prevention including employment of chemoprophylaxis. However, the limitation of the reviewed data mandates large scale prospective investigation to affirm this observation.

Gauging the treatment gap in dyslipidemia: findings from the 1999-2000 National Health and Nutrition Examination Survey.

BACKGROUND: Despite published guidelines and availability of many effective lipid-altering therapies, dyslipidemia in the United States remains largely underdiagnosed and undertreated. METHODS: This study used data from the 1999-2000 National Health and Nutrition Examination Survey to assess the current state of dyslipidemia management in the US adult population compared with guidelines issued by the Third Adult Treatment Panel of the National Cholesterol Education Program. Percentages were weighted to reflect population estimates, computed using SUDAAN (Research Triangle Institution, Cary, NC). RESULTS: Among 1,425 respondents aged > or = 20 years with complete data, 29.5% were eligible for therapeutic lifestyle changes (TLCs, 16.0%) or lipid-lowering drug therapy (LDT, 13.4%). Among high-risk adults, 79.3% were eligible for either TLC (35.7%) or LDT (43.6%). Only 43.7% of treatment-eligible adults reported ever being diagnosed with dyslipidemia. Of those diagnosed, 77.4% reported being told to undertake TLC, and 34.2% reported being told to take LDT. Of adults eligible for drug therapy, the average percentage reduction in low-density lipoprotein cholesterol (LDL-C) required to reach goal was 28.0% (standard error [SE] 1.1), and 41.9% required a reduction of > 30% in LDL-C to reach goal. Of high-risk adults eligible for drug therapy, the average required reduction was 36.9% (SE 1.4), and 76.3% required a reduction of > 30% in LDL-C. CONCLUSIONS: Despite advances in dyslipidemia therapy and changes in guidelines over the last decade, LDL-C continues to be inadequately managed among US adults. Of particular concern is the undertreatment of high-risk patients and failure of many treated patients to achieve LDL-C goal.
