Antibiotic use for respiratory tract infections among older adults living in long-term care facilities: a systematic review and meta-analysis

BACKGROUND

Antibiotics are commonly prescribed for respiratory tract infections (RTIs) among older adults in long-term care facilities (LTCFs), and this contributes to the emergence of antimicrobial resistance. The objective of this study was to determine the antibiotic prescribing rate for RTIs among LTCF residents, and to analyse the antibiotic consumption patterns with the AwaRe monitoring tool, developed by the World Health Organization.

METHODS

MEDLINE, EMBASE and CINAHL were searched from inception to March 2022. Original articles reporting antibiotic use for RTIs in LTCFs were included in this review. Study quality was assessed using the Joanna Briggs Institute's Critical Appraisal Checklist for Prevalence Data. A random-effects meta-analysis was employed to calculate the pooled estimates. Subgroup analysis was conducted by type of RTI, country, and study start year.

RESULTS

In total, 47 articles consisting of 50 studies were included. The antibiotic prescribing rate ranged from 21.5% to 100% (pooled estimate 69.8%, 95% confidence interval 55.2-82.6%). The antibiotic prescribing rate for lower respiratory tract infections (LRTIs) was higher than the rates for viral and general RTIs. Compared with Italy, France and the USA, the Netherlands had lower antibiotic use for LRTIs. A proportion of viral RTIs were treated with antibiotics, and all the antibiotics were from the Watch group. Use of antibiotics in the Access group was higher in the Netherlands, Norway, Switzerland and Slovenia compared with the USA and Australia.

CONCLUSION

The antibiotic prescribing rate for RTIs in LTCFs was high, and AWaRe antibiotic use patterns varied by type of RTI and country. Improving antibiotic use may require coordination efforts.

Heart Failure and Frailty in the Community-Living Elderly Population: What the UFO Study Will Tell Us

Heart failure and frailty are clinical syndromes that present with overlapping phenotypic characteristics. Importantly, their co-presence is associated with increased mortality and morbidity. While mechanical and electrical device therapies for heart failure are vital for select patients with advanced stage disease, the majority of patients and especially those with undiagnosed heart failure would benefit from early disease detection and prompt initiation of guideline-directed medical therapies. In this article, we review the problematic interactions between heart failure and frailty, introduce a focused cardiac screening program for community-living elderly initiated by a mobile communication device app leading to the Undiagnosed heart Failure in frail Older individuals (UFO) study, and discuss how the knowledge of pre-frailty and frailty status could be exploited for the detection of previously undiagnosed heart failure or advanced cardiac disease. The widespread use of mobile devices coupled with increasing availability of novel, effective medical and minimally invasive therapies have incentivized new approaches to heart failure case finding and disease management.

Effect of a new longitudinal interprofessional geriatric medicine educational track on knowledge and attitude of medical students: a controlled cohort study

A new interprofessional geriatric medicine curriculum was recently introduced at a large undergraduate Asian medical school. A longitudinal controlled interventional cohort study was conducted to evaluate the effect of the new curriculum on the knowledge and attitudes of medical students. The medical students under the new curriculum formed the intervention cohort, and those under the former curriculum formed the control cohort. To test knowledge, the University of California at Los Angeles (UCLA) geriatrics knowledge test (GKT) was used in Year 2 and the University of Michigan GKT in Year 5. Geriatrics attitudes were evaluated using the UCLA geriatrics attitudes test in Years 2 and 5. Not surprisingly, geriatrics knowledge at the end of Year 5 of medical school was enhanced to a greater degree in the intervention cohort than the control cohort, although improvements in geriatrics attitudes in each cohort were of similar magnitude by the end of Year 5, suggesting that factors other than a formal geriatrics curriculum influenced the improvements in geriatrics attitudes. This article is one of few published on the effectiveness of geriatrics curricular innovations using validated knowledge and attitude outcomes in a longitudinal controlled study design and will be useful to other medical institutions seeking to improve the geriatrics knowledge and attitudes of their students.
