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.

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.

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.

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.

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.

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.

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.

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.

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.

An international definition for "nursing home".

There is much ambiguity regarding the term "nursing home" in the international literature. The definition of a nursing home and the type of assistance provided in a nursing home is quite varied by country. The International Association of Gerontology and Geriatrics and AMDA foundation developed a survey to assist with an international consensus on the definition of "nursing home."

Survey of Potentially Inappropriate Prescription Using STOPP/START Criteria in Inha University Hospital.

BACKGROUND: Prescribing potentially harmful drugs and omitting essential drugs to older patients is a common problem because they take so many medications. In this study, our goal was to identify potentially inappropriate medications (PIMs) and potential prescribing omissions (PPOs) using Screening Tool of Older Persons' potentially inappropriate Prescriptions (STOPP) and Screening Tool to Alert doctors to the Right Treatment (START) criteria to improve proper prescription and reduce improper prescription. METHODS: Enrolled in this study were 117 patients older than 65 years old who were hospitalized at Inha University Hospital in Incheon due to pneumonia from January 2012 to March 2012. Patient data, including medical histories, current diagnoses, current medications, and biochemical data were recorded from electronic records. STOPP and START were applied to their clinical datasheets. RESULTS: STOPP criteria identified 24 patients who had 29 PIMs. Most potential inappropriate prescribing was of cardiovascular medications, followed by drugs whose primary effect is on the urogenital system and gastrointestinal system. START criteria identified 31 patients who had 46 PPOs. The cardiovascular system drugs comprised most of the PPOs. No PPOs were identified under the central nervous system criteria. CONCLUSION: Given the current Korean medical system conditions and considering the many clinically important situations when prescribing drugs, STOPP/START criteria are not absolute criteria to prevent improper prescription, but sagacious usage of these standards can help physicians to prescribe properly in clinical practice.
