International Trend of Non-Contact Healthcare and Related Changes Due to COVID-19 Pandemic

In response to the global spread of coronavirus disease-2019 (COVID-19), many countries have expanded access to non-contact healthcare. This study aimed to investigate the current state of non-contact healthcare in developed countries before and after the outbreak of the COVID-19 pandemic, and examine the potential clinical and political implications applicable to Korea. Before the COVID-19 outbreak, non-contact healthcare was provided to a limited extent. However, given the surge in COVID-19 cases, countries have lifted the restrictions on non-contact healthcare by expanding eligibility to patients and providers and the range of services. Countries that were slow to implement non-contact healthcare before the pandemic experienced a paradigm shift. Noncontact healthcare has advantages in maintaining essential health services while protecting patients and providers from viral infections. In Korea, non-contact healthcare was regarded as a business sector, so it has not been formally discussed from a public health standpoint. Given this global urgency, discussions should begin surrounding how to best utilize non-contact healthcare, considering the values, safety, and efficacy from the perspective of continuity of patient care. Non-contact healthcare should shift to utilizing a patient-centered approach. The step-by-step strategic planning of non-contact healthcare is imperative for ensuring value, quality, equity, and safety of services.

Preliminary Results of Teleconsultations Temporarily Allowed during the COVID-19 Pandemic

Purpose@#During the COVID-19 pandemic, Korea has temporarily expanded coverage of teleconsultation to ensure access to essential health services. As a preliminary study, we investigated service utilization patterns and the characteristics of doctors and patients involved in these temporary teleconsultation services. @*Materials and Methods@#Using national health insurance claims data from February 23, 2020 to June 30, 2020 from the Health Insurance Review and Assessment Service, 228269875 cases were identified. Among them, 567390 cases that received teleconsultation services were included in our study. We performed descriptive analyses according to the types of healthcare institutions. @*Results@#In total, 6193 healthcare institutions provided teleconsultation. Of these, 5466 (88.3%) were clinics. Physicians providing teleconsultations were most likely to be doctors of internal medicine (34.0%) or pediatricians (7.0%) and based in the Seoul Metropolitan area (30.4%). In terms of patients undergoing teleconsultation, the most common major disease categories treated were circulatory system diseases (I00–I99). In a detailed analysis, hypertensive diseases (I10–I15) were the most common diagnoses, with a total of 88726 cases (15.6%), followed by diabetes mellitus at 60298 cases (10.6%). The proportion of Medical Aid recipients receiving teleconsultations was higher (9.5%) than other socioeconomic groups. Among all participants, 356622 cases (84.6%) were from a return visit, and 108838 cases (19.2%) received teleconsultation services without being prescribed drugs. @*Conclusion@#Temporarily allowed teleconsultation services were provided mostly to the following patients: 1) those scheduled for revisitation, 2) those with chronic diseases, and 3) those living in pandemic hotspots.

The Trend of Acute Respiratory Tract Infections and Antibiotic Prescription Rates in Outpatient Settings using Health Insurance Data

OBJECTIVE: A significant concern has been raised about the emerging resistance that is largely caused by the excessive or inappropriate use of antibacterial agents for viral respiratory infections. This study investigated the trend of respiratory tract infections (RTIs) and the use of antibiotics. METHODS: Utilizing the national level health insurance claims data from 2005 to 2008, we examined encounter days, antibiotic use, and the prescription rate for respiratory tract infections including upper respiratory tract infections (URTIs), lower respiratory tract infections (LRTIs), and otitis media in outpatient settings. The antibiotic use was measured as defined daily dose per 1,000 patients per day (DDD/1,000 patients/day). RESULTS: The visit for URTI increased from 141,693,465 in 2005 to 120,717,966 in 2008 and the visit for LRTI decreased from 61,778,718 to 66,930,122. For RTIs, prescription rates of antibiotics decreased from 65.2% to 58.5% for URTIs and 76.9% to 68.3% for LRTIs from 2005 to 2008. The antibiotic use decreased to 20.85 DDD/1,000 patients/day after a significant increase of 22.01 DDD/1,000 patients/day in 2006. Among antibiotics, J01CR had the highest use- 7.93 DDD/1,000 patients/day followed by J01DC of 3.71 DDD/1,000 patients/day and J01FA of 3.2 DDD/1,000 patients/day. One notable trend is that J01FA presented a continuous increase in antibiotic use from 2.3 in 2005 to 3.26 DDD/1,000 patients/day in 2008. CONCLUSION: The use of antibiotics had poor compliance to guidelines for RTIs. Despite decrease in the use of antibiotics, prescription rates for URTIs were still about 50% indicating that the delayed prescribing antibiotics (or wait-and-see) were not observed.

Towards Actualizing the Value Potential of Korea Health Insurance Review and Assessment (HIRA) Data as a Resource for Health Research: Strengths, Limitations, Applications, and Strategies for Optimal Use of HIRA Data

Health Insurance and Review Assessment (HIRA) in South Korea, also called National Health Insurance (NHI) data, is a repository of claims data collected in the process of reimbursing healthcare providers. Under the universal coverage system, having fee-for-services covering all citizens in South Korea, HIRA contains comprehensive and rich information pertaining to healthcare services such as treatments, pharmaceuticals, procedures, and diagnoses for almost 50 million beneficiaries. This corpus of HIRA data, which constitutes a large repository of data in the healthcare sector, has enormous potential to create value in several ways: enhancing the efficiency of the healthcare delivery system without compromising quality of care; adding supporting evidence for a given intervention; and providing the information needed to prevent (or monitor) adverse events. In order to actualize this potential, HIRA data need to actively be utilized for research. Thus understanding this data would greatly enhance this potential. We introduce HIRA data as an important source for health research and provide guidelines for researchers who are currently utilizing HIRA, or interested in doing so, to answer their research questions. We present the characteristics and structure of HIRA data. We discuss strengths and limitations that should be considered in conducting research with HIRA data and suggest strategies for optimal utilization of HIRA data by reviewing published research using HIRA data.

A guide for the utilization of Health Insurance Review and Assessment Service National Patient Samples / 한국역학회지

The claims data of the Health Insurance Review and Assessment Service (HIRA) is an important source of information for healthcare service research. The claims data of HIRA is collected when healthcare service providers submit a claim to HIRA to be reimbursed for a service that they provided to patients. To improve the accessibility of healthcare service researchers to claims data of HIRA, HIRA has developed the Patient Samples which are extracted using a stratified randomized sampling method. The Patient Samples of HIRA consist of five tables: a table for general information (Table 20) containing socio-demographic information such as gender, age and medical aid, indicators for inpatient and outpatient services; a table for specific information on healthcare services provided (Table 30); a table for diagnostic information (Table 40); a table for outpatient prescriptions (Table 53) and a table for information on healthcare service providers (Table of providers). Researchers who are interested in using the Patient Sample data for research can apply via HIRA's website (https://www.hira.or.kr).

Primary Position Upbeat Nystagmus during an Acute Attack of Multiple Sclerosis

BACKGROUND AND PURPOSE: Ocular manifestation is one of the frequent signs of an acute attack in multiple sclerosis (MS), although primary position upbeat nystagmus (PPUN) is rare. The purpose of this study is to determine the incidence of PPUN in MS and to determine the lesions that are responsible for this sign. METHODS: The medical records of 120 MS patients with acute brain lesions were reviewed over a consecutive period of 9 years; of these, 6 patients were found to have PPUN. Other ocular motor abnormalities were analyzed in combination with upbeat nystagmus, video-oculographic findings, and lesions detected on brain MRI. RESULTS: Lesions in the pontine tegmentum involving the medial longitudinal fasciculus (MLF) and ventral tegmental tract (VTT) were the most common, being observed in three of the six patients with PPUN. One patient exhibited caudal medullary lesions bilaterally affecting the paramedian portion of the posterior tegmentum, and two patients exhibited multiple lesions involving the pons with the cerebral peduncle or medulla. In five patients, other ocular motor dysfunctions, such as gaze-evoked nystagmus (n=3) and internuclear ophthalmoplegia (n=1), were found in combination with upbeat nystagmus. CONCLUSIONS: PPUN is an infrequent, ocular manifestation noted during an acute attack of MS, and was observed in 5% of the present cases. Brainstem lesions in these cases primarily involved the pontine tegmentum and the caudal medulla. These findings support the theory that upbeat nystagmus is attributable to damage to the upward vestibulo-ocular reflex pathway related to the vestibular nucleus, VTT, and interconnecting pathways.

A Patient with Coexisting Myasthenia Gravis and Lambert-Eaton Myasthenic Syndrome

BACKGROUND: The coexistence of myasthenia gravis (MG) and Lambert-Eaton myasthenic syndrome (LEMS) is very rare and remains controversial. CASE REPORT: A 48-year-old woman initially presented with noticeable right ptosis and intermittent diplopia. She then developed fluctuating proximal limb weakness and difficulty in swallowing. The serum titer of anti-acetylcholine-receptor antibody was elevated and the edrophonium (Tensilon) test was positive. However, repetitive nerve stimulation revealed abnormalities typical of LEMS. The patient exhibited a good response to treatment with anticholinesterase inhibitors and steroids, and long-term evaluation disclosed that she presented with the clinical, electrophysiological, and immunological characteristics of both diseases. CONCLUSIONS: The reported clinical and electrophysiological features suggest that this patient was a very rare case of combined MG and LEMS.

A Case of Purpura Associated with Levetiracetam / 대한간질학회지

Levetiracetam has not been reported to cause purpura. We report a case of purpura associated with levetiracetam. A 81-year-old man suffered from post-stroke seizure. Seizure was well controlled with valproate. Valproate was discontinued due to pancytopenia and levetiracetam was prescribed when he was admitted with pneumonia. A few days later, he recovered from pancytopenia and pneumonia. However, he was rehospitalized due to multiple variable sized-purpura on the whole body surface without thrombocytopenia. After discontinuing levetiracetam, purpura disappeared.
