Evaluating Antimicrobial Utilisation in 20 Korean Long-Term Care Hospitals: A Call to Action for Antimicrobial Stewardship.

BACKGROUND: Evaluation of hospital-specific antimicrobial use is necessary for successful national antimicrobial stewardship. This study aimed to identify antimicrobial use in long-term care hospitals (LCHs) in Korea. METHODS: We conducted a multicentre retrospective study to evaluate the prescription patterns and appropriateness of antimicrobials in 20 LCHs in Korea. The medical record data of hospitalised patients who were newly prescribed antimicrobials at each hospital were collected manually between 10 July and 31 October 2023 to evaluate the appropriateness of antimicrobial use. RESULTS: The prevalence of antimicrobial prescriptions was 8.9% (365/4,086) and 10.3% (402/3,892) on July 12, 2023 and October 18, 2023, respectively. A total of 885 antimicrobials were prescribed to 740 patients. Among the antimicrobials, third- or fourth-generation cephalosporins (31.9%) represented the most prescribed antimicrobial class. A large majority of antimicrobials (855/885, 96.6%) were prescribed for the treatment of infectious diseases; however, only 37.7% (322/855) of antimicrobials were appropriately prescribed for infections. The route of administration, dosage, and prescribed antimicrobial were appropriate in 99.6% (852/855), 56.1% (480/855), and 62.0% (530/855) of cases, respectively. In total, 35.2% (252/715) of patients were appropriately prescribed antimicrobials. The diagnosis of infectious diseases was appropriate for 52.9% (472/892) of the cases. Of the 5, 15, and 10 antimicrobials used for surgical site infection prophylaxis, medical prophylaxis, and other purposes, respectively, none were appropriately used. CONCLUSION: The proportion of antimicrobials used appropriately is low in Korean LCHs. These data highlight the importance of establishing antimicrobial stewardship in LCHs.

Prescriptions patterns and appropriateness of usage of antibiotics in non-teaching community hospitals in South Korea: a multicentre retrospective study.

BACKGROUND: Although non-teaching community hospitals form the majority of healthcare providers in South Korea, there is limited data on antibiotic usage in them. To evaluate the pattern of antibiotic usage and its appropriateness in hospitals with < 400 beds in South Korea. METHODS: A multicentre retrospective study was conducted in 10 hospitals (six long-term care hospitals, three acute care hospitals, and one orthopaedic hospital), with < 400 beds in South Korea. We analysed patterns of antibiotic prescription in 2019, and their appropriateness in the participating hospitals. For the evaluation of the appropriateness of the prescription, 25 patients under antibiotic therapy were randomly selected at each hospital, over two separate periods. Due to the heterogeneity of their characteristics, the orthopaedics hospital was excluded from the analysis. RESULTS: The most commonly prescribed antibiotics in long-term care hospitals was fluoroquinolone, followed by beta-lactam/beta-lactamase inhibitor (anti-pseudomonal). In acute care hospitals, these were third generation cephalosporin, followed by first generation cephalosporin, and second generation cephalosporin. The major antibiotics that were prescribed in the orthopedics hospital was first generation cephalosporin Only 2.3% of the antibiotics were administered inappropriately. In comparison, 15.3% of patients were prescribed an inappropriate dose. The proportion of inappropriate antibiotic prescriptions was 30.6% of the total antibiotic prescriptions. CONCLUSIONS: The antibiotic usage patterns vary between non-teaching community hospitals in South Korea. The proportion of inappropriate prescriptions exceeded 30% of the total antibiotic prescriptions.

Bounce Forward Better: Geriatric and Gerontological Research in the Post-pandemic Future.

In recent years, we have faced challenges in managing coronavirus disease 2019 (COVID-19), especially in older adults. The pandemic has precipitated a global health crisis that impeded older adults from maintaining their health. Disruption of the routine management of chronic diseases, physical inactivity deteriorating physical function and quality of life, malnutrition, and mental disorders have been suggested as major threats to the health of older adults. To address these problems and facilitate reactivation of normal care activities, this article summarizes the contents of a webinar held by the Annals of Geriatric Medicine and Research (AGMR) regarding the future directions of geriatric medicine and research in the post-COVID-19 era.

Challenges and Opportunities for Academic Journals to Serve the Older Population in Western Pacific Region.

Annals of Geriatric Medicine and Research held its inaugural international editorial board virtual meeting on September 16, 2021, to brainstorm ideas for sustainable growth. This special article summarizes the key concepts obtained from the webinar proceedings, with further development of ideas from ensuing discussions occurring after the meeting. From the initial discussion points provided by eight editorial board members, including six presenters, email discussions further enriched these ideas to construct the current special article. The key points discussed were: impactful research and impact factors, international and Asian perspectives, and challenges to sustainable growth. The editors noted the existing gap between the impact factor and research impact as a challenge for the growth paths of regional journals. However, they agreed that persevering with impactful research would ultimately translate into parallel and gradual gains in impact, which is, therefore, consistent with the organic growth of the journal. Acknowledging challenges in navigating between unique Asian perspectives and international outlooks, the editors encouraged academic journals to serve as bridges linking international evidence with the richness of local perspectives. For sustainable growth, the editors suggested that journals may be forged into the academic ecosystems of the region, diversify value streams, and establish themselves as reputable brands in disciplines. By combining these discussions, we proposed the "IMPACT" strategy for journals on the growth path in the region, which stands for IMmersive user experience encompassing authors, reviewers, and readers; Pasteur's quadrant use-inspired research; Asia-Pacific context; Collaborative; and Translation to practice and policy.

Long-Term Care System in Korea.

Korea is a country with unexpectedly fast ageing speed, which gives burden on caregivers of older adults. Thanks to long-term care insurance and national health insurance system, most people who need long-term care are currently staying in long-term care facilities like nursing homes and long-term care hospitals. However, new project of integrated community care system is under trial implementation. This review demonstrates perspectives on Korean long-term care system from the past to the future.

Development and Application of a Surveillance Method for Healthcare-Associated Infections in Long-Term Care Hospitals in Korea.

BACKGROUND: This study developed a surveillance method for healthcare-associated infections (HAIs) in long-term care hospitals (LTCHs) and investigated the current status of HAIs in LTCHs in Korea. METHODS: We applied the HAI-related surveillance criteria for long-term care facilities developed by McGeer in six LTCHs. RESULTS: The 197 confirmed HAIs corresponded to incidence rates of 30.38/100 inpatients and 1.57/1,000 days of hospitalization and included 84 cases of respiratory tract infection (43.8%), 78 cases of systemic infection (40.6%), 24 cases of gastrointestinal tract infection (12.5%), and 6 cases of skin and soft tissue mucosal infection (2.1%). The subtypes included 78 cases of unexplained febrile illness (40.6%); 40 cases of pneumonia (20.8%); 27 cases of lower respiratory tract infection (14.1%); 21 cases of gastroenteritis (10.9%); 9 cases of influenza-like illness (4.7%); 8 cases of common cold or pharyngitis (4.2%); 4 cases of cellulitis, soft tissue, or wound infection (2.1%); 3 cases of Clostridium difficile infection (1.6%); 1 case of conjunctivitis (0.5%); and 1 case of fungal oral/perioral and skin infection (0.5%). CONCLUSION: Establishing an HAI surveillance method for LTCHs and identifying HAI rates and risk factors among LTCH patients may help prevent HAIs in LTCHs in Korea.

Cut-Off Scores of an Olfactory Function Test for Mild Cognitive Impairment and Dementia.

OBJECTIVE: We aimed to find the optimal cut-off scores for screening of odor detection threshold, odor discrimination, and odor identification tests for detection of mild cognitive impairment (MCI) and dementia in Korean elderly. METHODS: A total of 195 elderly people were divided into three groups: the normal cognition (NC), MCI, and dementia groups. All participants underwent neurocognitive and olfactory function tests. We used k-means cluster analysis and receiver operating characteristic (ROC) analysis to identify the most appropriate cut-off value. RESULTS: To distinguish the MCI from NC groups, odor identification [area under the curve (AUC)=0.670, p<0.007] with a cut-off point of 7 showed greater validity for screening (sensitivity/specificity=0.462/0.837) than did other olfactory function tests. To distinguish the MCI and dementia from NC as well, odor identification (AUC=0.817, p=0.002) with a cut-off point of 7 showed the highest validity for screening (0.785/0.654). To distinguish MCI from AD, an odor detection threshold (AUC=0.722, p=0.001) with a cut-off point of 2 showed the highest validity for screening (0.785/0.654). CONCLUSION: Olfactory function tests may be a useful screening tool for cognitive decline before clinical symptoms of dementia have completely developed. This tool can be used as a supplementary tool to enhance the sensitivity of traditional cognitive tests to screen for dementia.

Impaired Odor Identification of Culturally Familiar Odorants Associated with Dementia in South Korean Older Adults.

Among olfactory functions, odor identification is the most studied predictor of dementia. We aimed to verify whether patients with dementia are less aware of specific odors than cognitively normal individuals using an odor identification test, which includes odorants that are culturally familiar to South Koreans. We divided 139 older adults aged 57-79 years into the dementia and normal cognition groups. Odor identification function was assessed in all participants. We conducted hierarchical logistic regression analyses with the diagnosis of dementia as a dependent variable and three demographic characteristics, as well as 12 odor identification items, as independent variables. Impaired odor identification for herbal medicine (odds ratio (OR) = 9.420; p = 0.012) and Korean grilled meat (OR = 5.361; p = 0.019) and older age (OR = 1.176; p = 0.005) were significant predictors of dementia. Impaired odor identification of culturally familiar odorants was associated with dementia risk. This may be explained by the fact that compared with culturally non-specific universal odorants, familiar odorants are more related to episodic memory, which is impaired in the early stages of dementia. Thus, an optimal combination of odor identification items should be used for screening individuals with cognitive decline requiring further neurocognitive function tests.

Korean frailty and aging cohort study (KFACS): cohort profile.

PURPOSE: The purpose of the Korean Frailty and Aging Cohort Study (KFACS) is to initiate a nationwide, population-based prospective cohort study of older adults living in the community to assess their frailty status and explore transitions between frailty states over time in Korea. PARTICIPANTS: The KFACS is a multicentre longitudinal study with the baseline survey conducted from May 2016 to November 2017. Each centre recruited participants using quota sampling stratified by age and sex. The number of participants recruited through 2 years of baseline study from 10 centres was 3014, with each site accounting for approximately 300 participants. The inclusion criteria were: having an age of 70-84 years, currently living in the community, having no plans to move out in the next 2 years, having no problems with communication and no prior dementia diagnosis. FINDINGS TO DATE: To define physical frailty, the KFACS used a modified version of the Fried Frailty Phenotype (FFP) consisting of five components of frailty: unintended weight loss, weakness, self-reported exhaustion, slowness and low physical activity. In the baseline study of 2016-2017, 2907 of 3014 individuals fulfilled all five components of FFP. The results indicated that 7.8% of the participants (n=228) were frail, 47.0% (n=1366) were prefrail and 45.2% (n=1313) were robust. The prevalence of frailty increased with age in both sexes; in the group aged 70-74 years, 1.8% of men and 3.7% of women were frail, whereas in the 80-84 years age group, 14.9% of men and 16.7% of women were frail. Women tended to exhibit a higher prevalence of frailty than men in all age groups. FUTURE PLANS: The KFACS plans to identify outcomes and risk factors associated with frailty by conducting a 10-year cohort study, with a follow-up every 2 years, using 3014 baseline participants.

Biosignals to Detect the Imbalance of Explicit and Implicit Affect in Dementia: A Pilot Study.

BACKGROUND: We assessed implicit and explicit emotion in older patients with dementia using biosignals. METHODS: Fifty patients with dementia and 34 healthy individuals watched 3 videos that aimed to elicit various emotional responses. Electroencephalogram and heart rate variability were recorded. RESULTS: Patients with dementia experienced less fun and more fear than controls. The high frequency (HF) from the baseline in response to funny stimulation as well as HF from neutral to fear stimulation in the dementia group increased further than in the control group. The slow wave (SW)-fast wave (FW) ratio from neutral to funny stimulation in the control group increased further than in the dementia group. The SW-FW from neutral to fear stimulation was further decreased in the dementia group than in the control group. CONCLUSIONS: Although patients with dementia were more sensitive to implicit affect, they showed more enhanced imbalance between positive and negative affect in explicit affect assessment.

Use of the Frailty Index and FRAIL-NH Scale for the Assessment of the Frailty Status of Elderly Individuals Admitted in a Long-term Care Hospital in Korea.

BACKGROUND: Numerous elderly individuals with multimorbidity and impaired function are admitted in long-term care hospitals (LTCHs) in Korea. In this study, we aimed to describe the frailty status of elderly patients admitted in a LTCH using the FRAIL-NH scale and to identify the clinical relevance of frailty status on clinical outcomes, including death. METHODS: We retrospectively reviewed the medical records of 100 elderly patients who were hospitalized and died in an LTCH from March 2011 to February 2017. The monthly assessment results obtained from the inpatients' data set (IDS) were used as main data sources for the 6-item FRAIL-NH scale and frailty index that was composed of 22 newly established items. RESULTS: The mean frailty index of the patients included in the analysis (mean age, 81.5±7.2 years; men, 53%) was 0.60 (standard deviation [SD], 0.10; range, 0.28-0.80). The distribution of the FRAIL-NH score in this population was in accordance with the 22-item frailty index, which shows a standardized beta of 0.571 (p<0.001, R=0.572). When the patients were categorized based on the FRAIL-NH score, the mean survival durations of the more fail group (FRAIL-NH >10, n=49) and less frail group (FRAIL-NH ≤10, n=51) were 529.3 days (SD, 453.4) and 888 days (SD, 679.9), respectively. Similarly, the frailty index was associated with earlier mortality. CONCLUSION: Frailty is extremely common in elderly patients admitted in an LTCH and can be easily measured using the FRAIL-NH scale that utilizes the IDS of LTCHs in Korea. Since frailty is associated with earlier mortality, the assessment of frailty status in patients admitted in LTCHs may be helpful in clinical decision-making.

Development of a Consensus List of Potentially Inappropriate Medications for Korean Older Adults.

BACKGROUND: Korea has recently attained the aged society status and the growth rate of the aging population will be among the most rapid worldwide. The objective of this study was to develop a credible list of potentially inappropriate medications (PIMs) for Korean older adults. METHODS: A new Korean PIMs list was produced through a comprehensive structured expert survey (modified Delphi method). To generate an expert panel, we invited the nomination of experts in geriatric medication from the Korean Geriatric Society, the Korean Academy of Clinical Geriatrics, the Korean Academy of Family Medicine, the Korean Association for Geriatric Psychiatry, and the Korean Association of Geriatric Hospitals. Based on their recommendation, the expert panel consisted of 14 geriatric specialists, including 10 geriatricians (7 family medicine doctors and 3 internal medicine doctors), 3 geriatric psychiatrists, and 1 clinical pharmacist. After 4 rounds, the new Korean PIMs list was finalized. RESULTS: Sixty-two drugs were classified as PIMs for older adults irrespective of comorbidities, including antipsychotics, tricyclic antidepressants, benzodiazepines, non-steroidal anti-inflammatory drugs, and first-generation antihistamines. Forty-eight drugs or drug categories were classified as PIMs for 18 specific conditions that older adults encounter frequently. The expert panel presented the rationale and comments including preferred therapeutic alternatives and exceptional situations for each item. CONCLUSION: We presented a "user-friendly" PIMs list for Korean older adults. Further prospective studies to validate its usefulness in clinical settings and regular updating of the list are required. It is also important to disseminate this list to doctors who prescribe medication to older people.

Korean travelers' knowledge, attitudes, and practices regarding the prevention of malaria: measures taken by travelers departing for India from Incheon International Airport.

BACKGROUND: Although many Koreans travel each year to countries where malaria is present, few data are available on the knowledge, attitudes, and practices of Koreans with regards to malaria. METHODS: The study was conducted in the departure lounge of Incheon International Airport in May 2006. A 22-item questionnaire was administered to Korean travelers whose travel destination was India. RESULTS: Of 188 respondents, 24% had sought pretravel health information. Independent predictors for seeking pretravel health information were the following: being a Korean woman, longer duration of travel, planning to travel independently or to a rural area, and perceived risk of malaria. A total of 47% of travelers answered that they had not perceived any risk of malaria, and only 7% of travelers carried malaria prophylaxis. CONCLUSIONS: There is an urgent need for increased awareness about travel-related infectious diseases (especially malaria) among Korean travelers, and they should be encouraged to seek pretravel health information.

Intramuscular and nerve root stimulation vs lidocaine injection to trigger points in myofascial pain syndrome.

OBJECTIVES: To compare the efficacies of an intramuscular stimulation technique and 0.5% lidocaine injection to trigger points in myofascial pain syndrome. PARTICIPANTS: Forty-three people with myofascial pain syndrome of the upper trapezius muscle. INTERVENTIONS: Twenty-two subjects were treated with intramuscular stimulation and another 21 with 0.5% lidocaine injection at all the trigger points on days 0, 7 and 14. RESULTS: Intramuscular stimulation resulted in a significant reduction in Wong-Baker FACES pain scale scores at all visits and was more effective than trigger point injection. Intramuscular stimulation also resulted in significant improvement on the Geriatric Depression Scale - Short Form. Local twitch responses occurred in 97.7% (42/43) of patients. All the passive cervical ranges of motion were significantly increased. Post-treatment soreness was noted in 54.6% of patients in the intramuscular stimulation group and 38.1% in the trigger point injection group, respectively, and gross subcutaneous haemorrhage (> 4 cm2) was seen in only one patient in the trigger point injection group. CONCLUSION: In managing myofascial pain syndrome, after one month intramuscular stimulation resulted in more significant improvements in pain intensity, cervical range of motion and depression scales than did 0.5% lidocaine injection of trigger points. Intramuscular stimulation is therefore recommended for myofascial pain syndrome.

Dry needling of trigger points with and without paraspinal needling in myofascial pain syndromes in elderly patients.

OBJECTIVES: To compare the efficacies of dry needling of trigger points (TrPs) with and without paraspinal needling in myofascial pain syndrome of elderly patients. DESIGN: Single-blinded, randomized controlled trial. SUBJECTS: Forty (40) subjects, between the ages of 63 and 90 with myofascial pain syndrome of the upper trapezius muscle. INTERVENTIONS: Eighteen (18) subjects were treated with dry needling of all the TrPs only and another 22 with additional paraspinal needling on days 0, 7, and 14. RESULTS: At 4-week follow-up the results were as follows: (1) TrP and paraspinal dry needling resulted in more continuous subjective pain reduction than TrP dry needling only; (2) TrP and paraspinal dry needling resulted in significant improvements on the geriatric depression scale but TrP dry needling only did not; (3) TrP and paraspinal dry needling resulted in improvements of all the cervical range of motions but TrP dry needling only did not in extensional cervical range of motion; and (4) no cases of gross hemorrhage were noted. CONCLUSIONS: TrP and paraspinal dry needling is suggested to be a better method than TrP dry needling only for treating myofascial pain syndrome in elderly patients.

Acupuncture needling versus lidocaine injection of trigger points in myofascial pain syndrome in elderly patients--a randomised trial.

AIM: To compare the efficacy of acupuncture needling and 0.5% lidocaine injection of trigger points in myofascial pain syndrome of elderly patients. METHODS: Thirty nine participants with myofascial pain syndrome of one or both upper trapezius muscles were randomised to treatment with either acupuncture needling (n=18) or 0.5% lidocaine injection (n=21) at all the trigger points on days 0, 7 and 14, in a single-blinded study. Pain scores, range of neck movement, pressure pain intensity and depression were measured up to four weeks from the first treatment. RESULTS: Local twitch responses were elicited at least once in 94.9% of all subjects. Both groups improved, but there was no significant difference in reduction of pain in the two groups at any time point up to one month. Overall, the range of cervical movement improved in both groups, apart from extension in the acupuncture needling group. Changes in depression showed only trends. CONCLUSION: There was no significant difference between acupuncture needling and 0.5% lidocaine injection of trigger points for treating myofascial pain syndrome in elderly patients.
