Purpose: The aim of this study was to systematically analyze the prescription trends of medical narcotic appetite suppressants in South Korea. Materials and Methods: Data was extracted from the Narcotics Information Management System dataset from 2020, which encompasses nationwide information concerning the use of medical narcotics. The selected variables for this study included the types of prescribed medical narcotic appetite suppressants, gender, age, region, and the category of medical institution. Regional prescription trends were compared by utilizing the defined daily doses for statistical purposes (S-DDD). Results: The prescription of medical narcotic appetite suppressants was predominantly for females (94%), with the highest prescription rates identified in the 30–40 age group. The majority of these prescriptions were dispensed by clinics. Within the category of narcotic appetite suppressants, phentermine and phendimetrazine were found to have higher prescription rates. Notably, the region of Daegu recorded the highest S-DDD value (12.66) in phentermine consumption. Conclusion Our findings underscore the need for governmental policy and guidance to address the risks linked to the long-term use of medical narcotic appetite suppressants. This is crucial to ensure their safe and efficacious prescription and administration.

OBJECTIVE: This study was conducted to evaluate payer-driven medication adherence intervention program from the patient's and counselor's perspectives. METHODS: Target patients for intervention were selected by retrospective adherence measures based on national health insurance claims data for hypertension, diabetes and hyperlipidemia. As a serial intervention for higher risk groups of medication non-adherence, initial direct mailing, the first direct telephone call and the second direct call or a home visit were followed. Interview approach to qualitative inquiry was used to evaluate intervention results. RESULTS: Participants including 4 patients received telephone calls, and 4 National Health Insurance Service staff and 4 pharmacists participated as counselors were interviewed regarding their impression of the intervention program. Three major themes arose: overall perception; necessities; and suggestions for success, of the intervention. Despite short period of intervention, educational intervention by telephone counseling involving pharmacists shows potential to improve self-management of chronic disease, and pharmacist-involvement. But more sophisticated selection of target patients requiring the intervention and complementation of electronic database system would be necessary. In addition, personal disposition of counselor was revealed to be an important factor for achieving successful outcome of intervention. CONCLUSION: The findings suggest that the individualized counseling intervention would be an efficient option for improved medication adherence. Further researches should include longer periods of interventions, a quantitative analysis using adherence measures based on claims data and consideration of clinical benefits associated with the intervention.

Purpose: We compared cost-effectiveness parameters between inpatient and homebased hospice-palliative care services for terminal cancer patients in Korea. Methods: A decision-analytic Markov model was used to compare the cost-effectiveness of hospicepalliative care in an inpatient unit (inpatient-start group) and at home (home-start group). The model adopted a healthcare system perspective, with a 9-week horizon and a 1-week cycle length. The transition probabilities were calculated based on the reports from the Korean National Cancer Center in 2017 and Health Insurance Review & Assessment Service in 2020. Quality of life (QOL) was converted to the quality-adjusted life week (QALW).Modeling and cost-effectiveness analysis were performed with TreeAge software. The weekly medical cost was estimated to be 2,481,479 Korean won (KRW) for inpatient hospice-palliative care and 225,688 KRW for home-based hospice-palliative care. One-way sensitivity analysis was used to assess the impact of different scenarios and assumptions on the model results. Results: Compared with the inpatient-start group, the incremental cost of the home-start group was 697,657 KRW, and the incremental effectiveness based on QOL was 0.88 QALW. The incremental cost-effectiveness ratio (ICER) of the home-start group was 796,476 KRW/QALW. Based on one-way sensitivity analyses, the ICER was predicted to increase to 1,626,988 KRW/QALW if the weekly cost of home-based hospice doubled, but it was estimated to decrease to -2,898,361 KRW/QALW if death rates at home doubled. Conclusion Home-based hospice-palliative care may be more cost-effective than inpatient hospice-palliative care. Home-based hospice appears to be affordable even if the associated medical expenditures double.

Purpose: The aim of this study was to determine the effect of visual impairment (VI) onset on the use of healthcare services across four types of institutions in South Korea. Materials and Methods: We utilized data from the National Health Insurance Service database from 2006 to 2015 for 714 persons who experienced VI onset in 2009–2012 and for 2856 matched persons for a 1:4 ratio of matching controls. We compared trends in healthcare use and expenditures for eye diseases at clinics, hospitals, general hospitals, and tertiary teaching hospitals using 3 years of data prior to and after the onset of VI. Results: The inpatient and outpatient healthcare expenditures of individuals with VI were higher than those without VI, peaking at the pre-VI onset period in tertiary teaching hospitals. During the pre-VI onset period, the proportion of healthcare expenditures attributed to eye diseases ranged 11%–40.8% among individuals with VI, but 1.9%–11% among individuals without VI at the four types of institutions. The differences in healthcare use between the pre- and post-VI periods were primarily observed in tertiary teaching hospitals for inpatient care. There was a peak in utilization of outpatient care in the year preceding VI onset at tertiary teaching hospitals, clinics, and hospitals, but there was a decrease in outpatient care over time during the post-VI period. Conclusion Our findings suggest economic burden of healthcare in tertiary teaching hospitals during pre-VI onset period and a potential lack of regular management and continuity of care in post-VI periods.

Objective: The disabled are in a blind spot for obtaining information on drugs, and the pharmacies’ counseling on drug use is centered on non-disabled people. Few studies have investigated the current statuses of drug use by type of disability. The purpose of this study is to understand the drug use by type of disability and by life cycle of visually impaired and hearing impaired in Korea. Methods: The study participants consisted of 16 people with visually impairments, 12 people with hearing impairments. One indepth interview was conducted per participant, and each interview was recorded and documented. Results: Common barriers against safe medication and medical service uses across disability types are ‘lack of consideration and service for the disabled, limited access to medical facilities due to disability, limited access to information regarding medication use, psychological anxiety about drug use and side effects, and inconvenience regarding COVID-19 epidemic. The specific factors were ‘difficulties in identifying proper medicines and following prescribed dosages’ in the case of visually impaired, and ‘problems with sign language interpretation system’ for the hearing impaired. Conclusion Disabled people are hindered from using medicines properly due to various factors. Based on the content derived from this study, it is necessary to eliminate the inhibition factors and devise specific measures for the safety of each type of disorder such as developing a method for medication counseling considering disabilities and establishing communication support systems.

OBJECTIVE: The visually impaired have limited access to health care services and related information, and thus, they can have serious hurdles against properly taking medications. Despite that it is important to improve self-care ability of the visually impaired for correct medication use, there have been few studies investigating their needs for health care services in Korea, particularly focusing on proper medication usage. This study is to explore safety-related issues regarding mediation usage among the visually impaired based on in-depth interview. We particularly focus on any obstacles for safe use of medicines including experience on medication-related adverse effects in order to provide preliminary evidence for policy measures to improve proper medication use among the visually impaired. METHODS: Study sample was visually impaired individuals who resided in Seoul area and were registered in the National Association of Visually Impaired. The association helped the process of recruiting the study participants. In-depth interview for each study participants was conducted. Each interview was recorded and later converted into a written script to extract core contents for the analysis. RESULTS: The study participants comprised of three women (42.9%) and four men (57.1%). One was in his 20's, and there were four participants in 30's and two in 40's. Fully impaired participants were majority (5 out of 7). Limitation to physical access to health care providers and health information were the key factors to hamper safe medication utilization among the study participants. Difficulty reading medication information and may take the wrong medication or incorrect doses of medication, resulting in serious consequences, including overdose or inadequate treatment of health problems. Visually impaired patients report increased anxiety related to medication management and must rely on others to obtain necessary drug information. Pharmacists have a unique opportunity to pursue accurate medication adherence in this special population. This article reviews literature illustrating how severe medication mismanagement can occur in the visually impaired elderly and presents resources and solutions for pharmacists to take a larger role in adherence management in this population. CONCLUSION: The visually impaired had difficulties reading medication information and identifying medicines, and took incorrect doses of medications. Public support for safe medication use and medication management among the visually impaired is necessary.

PURPOSE: The current study investigated the association of body mass index with asthma and allergic diseases among adolescents in Incheon, South Korea. METHODS: The study sample included 2,140 teenagers living in Incheon. The standard questionnaires of the International Study of Asthma and Allergies in Childhood study were used to survey the prevalence of asthma, allergic rhinitis, and atopic dermatitis. In addition, family history of allergic diseases, height, and weight were collected via self-report. RESULTS: The average body mass index was higher in male adolescents with asthma (21.38 kg/m2) than in those without (20.19 kg/m2). Body mass index of male adolescents was associated asthma and atopic dermatitis (odds ratio [OR], 1.074; 95% confidence interval [CI], 1.008-1.143; P=0.026 for asthma and OR, 1.072; 95% CI, 0.998-1.150; P=0.056 for atopic dermatitis) after adjustment for family history of allergic diseases, age, and school as covariates. CONCLUSION: Asthma, allergic rhinitis, and atopic dermatitis are of highly prevalent in adolescents living in Incheon. Obesity may be associated with asthma in male adolescents.

OBJECTIVES: The goal of this study was to examine the association of various demographic and socioeconomic factors with risk factors for chronic kidney disease (CKD). METHODS: We used nationally representative pooled data from the Korea National Health and Nutrition Examination Survey (KNHANES), 2007-2013. We estimated the glomerular filtration rate (GFR) using the Modification of Diet in Renal Disease equation. We defined CKD as a GFR <60 mL/min/1.73 m2, and 1304 of the 45 208 individuals included in the KNHANES were found to have CKD by this definition. The outcome variable was whether individual subjects adhered to the CKD prevention and management guidelines recommended by the Korea Centers for Disease Control and Prevention. The guidelines suggest that individuals maintain a normal weight, abstain from alcohol consumption and smoking, manage diabetes and hypertension, and engage in regular exercise in order to prevent and manage CKD. RESULTS: This study found that individuals with CKD were more likely to be obese and have hypertension or diabetes than individuals without CKD. In particular, male and less-educated CKD patients were less likely to adhere to the guidelines. CONCLUSIONS: Although the prevalence of CKD, as indicated by the KNHANES data, decreased from 2007 to 2013, the prevalence of most risk factors associated with CKD fluctuated over the same time period. Since a variety of demographic and socioeconomic factors are related to the successful implementation of guidelines for preventing and managing CKD, individually tailored prevention activities should be developed.

OBJECTIVE: Because of communication difficulties, the hearing-impaired face many disadvantages throughout their lives. One of those is limited access to health care services, particularly medication service. Though they suffer from problems related to taking medication properly, there have been few studies on their actual condition of medication use in Korea. This study is to investigate any obstacles to properly taking medications and, therefore, to suggest preliminary evidence for policy measures to improve safe medication use among the hearing-impaired. METHODS: Study participants consisted of hearing-impaired individuals living in Seoul. We also interviewed two sign language interpreters in order to illuminate health care state of the hearing-impaired. In-depth interview for each study participant was recorded and was translated into a written script for analysis. RESULTS: Study participants were comprised of four women (66.6%) and two men (33.3%). There were one participants in 20's, two participants in 30's, one 40's, and two 50's. Sign language interpreters were all women. One was in her 30's and the other was in her 40's. Communication difficulties have been found to be key barrier to use medication safely. A negative image of pharmacists also hinders safe medication usage, lowering access to local pharmacy and leading discretional self-medication. This article provides pharmacists with solutions to promote adherence in this population. CONCLUSION: The hearing-impaired had limited access to medication-related information as well as using services in a hospital and local pharmacy due to their disability. Institutional improvement for safe medication usage among the hearing-impaired is necessary.

Purpose: Polypharmacy can cause drug-related problems, such as potentially inappropriate medication (PIM) use and medication regimen complexity in the elderly. This study aimed to investigate the feasibility and effectiveness of a collaborative medication review and comprehensive medication reconciliation intervention by a pharmacist and hospitalist for older patients. Materials and Methods: This comprehensive medication reconciliation study was designed as a prospective, open-label, randomized clinical trial with patients aged 65 years or older from July to December 2020. Comprehensive medication reconciliation comprised medication reviews based on the PIM criteria. The discharge of medication was simplified to reduce regimen complexity. The primary outcome was the difference in adverse drug events (ADEs) throughout hospitalization and 30 days after discharge. Changes in regimen complexity were evaluated using the Korean version of the medication regimen complexity index (MRCI-K). Results: Of the 32 patients, 34.4% (n=11/32) reported ADEs before discharge, and 19.2% (n=5/26) ADEs were reported at the 30-day phone call. No ADEs were reported in the intervention group, whereas five events were reported in the control group (p=0.039) on the 30-day phone call. The mean acceptance rate of medication reconciliation was 83%. The mean decreases of MRCI-K between at the admission and the discharge were 6.2 vs. 2.4, although it was not significant (p=0.159). Conclusion As a result, we identified the effect of pharmacist-led interventions using comprehensive medication reconciliation, including the criteria of the PIMs and the MRCI-K, and the differences in ADEs between the intervention and control groups at the 30-day follow-up after discharge in elderly patients.Trial Registration: (Clinical trial number: KCT0005994)
