Epidemiology and Clinical Characteristics of Older Patients Transferred from Long-Term-Care Hospitals (LTCHs) to Emergency Departments by a Comparison with Non-LTCHs in South Korea: A Cross-Sectional Observational Study

Trends of antimicrobial susceptibilities and multidrug-resistant colonization rate in patients transferred from long-term care facilities during 2017-2022: a cross-sectional study

BACKGROUND

With the global increase in the older population, the proportion of those receiving care in long-term care facilities (LTCFs) has also been increasing. We assessed the epidemiology, antibiotic susceptibility, and colonization status of drug-resistant organisms in patients transferred from LTCFs.

METHODS

We retrospectively reviewed the medical records of patients transferred from LTCFs between 2017 and 2022. The reasons for admission, antimicrobial susceptibility, and colonization rates of carbapenem-resistant Enterobacterales (CRE), methicillin-resistant Staphylococcus aureus (MRSA), and carbapenem-resistant Acinetobacter baumannii (CRAB) were recorded. We analyzed the susceptibility and colonization rates by year to identify trends.

RESULTS

Of the 936 patients transferred from LTCFs, 54.3% were admitted to the intensive care unit and 12.5% died. The most common reason for admission was infection (n = 573, 61.2%), followed by gastrointestinal bleeding (n = 67, 7.2%) and cerebrovascular disorder (n = 65, 6.9%). A total of 452 Enterobacterales strains were isolated, and their susceptibility rates to ciprofloxacin and cefotaxime were 33.3% and 35.6%, respectively. A total of 54.9% were extended-spectrum beta-lactamase-producing strains, and 4.9% of them were carbapenem-resistant, both of which showed an increasing trend (P = 0.024 and P < 0.001, respectively). The prevalence rates of CRE, CRAB, and MRSA colonization were 9.2%, 7.1%, and 23.1%, respectively. CRE colonization showed a significant increase (P < 0.001), with carbapenemase-producing Enterobacterales accounting for 75.9% of cases.

CONCLUSIONS

Patients transferred from LTCFs are primarily affected by infections and exhibit high resistance rates. The increasing trend in CRE colonization rates each year highlights the need for the implementation of rigorous infection control measures for effective management.

Epidemiology and clinical characteristics of trauma in older patients transferred from long-term care hospitals to emergency departments: A nationwide retrospective study in South Korea

BACKGROUND

South Korea's aging population had leg to an increased number of long-term care hospitals (LTCHs), and increased transfer of older patients to emergency departments (EDs). This study investigated the epidemiological and injury profiles of LTCH patients aged ≥65 who were transferred from LTCHs to EDs due to trauma.

METHOD

This retrospective study conducted between January 2014 and December 2019 in South Korea utilized data from the National Emergency Department Information System. The requirement for informed consent was waived by the IRB due to the retrospective nature of the study. Patient information was anonymized prior to analysis.

RESULTS

Of the 1,472,006 trauma cases aged ≥65, 14,469 came from LTCHs. Outcomes varied: 44.1% were discharged, 40.6% were admitted to general wards (GW), 5.9% to intensive care units (ICU), 2.4% to other hospitals, and 6.5% returned to LTCHs. ED length of stay (LOS) was longest in the death (410.28 ± 559.73 min) and GW admission (390.12 ± 621.71 min) groups. Falls were the main cause of injury (50.1%), and the most common fracture was femoral (71.6%). Femoral and shoulder/upper extremity fractures increased hospitalization risk only, whereas self-harm increased both hospitalization and mortality risk.

CONCLUSION

Visits to the ED by older patients from LTCH for trauma were avoidable in 50.6% of cases. Additionally, these patients had longer ED LOS and higher hospitalization rates than non-LTCH patients. Falls were the predominant mode of presentation, femoral fracture was the most common fracture among patients from LTCH.
