Admissions and Mortality Related to Urinary Tract Infections in Male Veterans with Dementia.

Objective To examine mortality and hospital readmission rates in male veterans with dementia diagnosed with urinary tract infection (UTI) compared with patients without dementia. Design Retrospective cohort study. Setting Veterans Healthcare Systems (VA). Participants Male inpatients with a diagnosis of UTI who were treated at any VA Healthcare Center from January 1, 2009, to December 31, 2018. Interventions None. Main Outcome Measures Mortality and hospital readmission for patients with and without dementia at 30, 60, and 90 days from UTI diagnosis. Results 262,515 veterans admitted with UTI were analyzed, and 58,940 (22.5%) had dementia. The mean age for veterans with dementia was 80.0 +/- 9.7 years. Veterans with dementia experienced less mortality than patients without dementia at 30 days (8.3% vs 8.5%; P < 0.001), but more mortality at 60-day (4.9% vs 4.7%; P < 0.001) and 90-day (3.6% vs 3.3%; P < 0.001) intervals. Death was 20% less likely at 30 days in patients with dementia. Veterans with dementia were readmitted more than those without dementia at 30-day (18.4% vs 16.0%), 60-day (4.5% vs 2.8%), and 90-day (3.4% vs 2.5%) intervals; P < 0.0001. Conclusion Though patients with dementia are at an increased risk for death long-term, risk of death is less than those without dementia shortly following UTI diagnosis. This highlights the possibility that veterans with dementia may be hospitalized and diagnosed with UTIs when in actuality they have asymptomatic bacteriuria. Patients with dementia and UTI therefore represent an important group of geriatric patients that could benefit from the oversight of a senior care pharmacist to help prevent unnecessary treatment of asymptomatic bacteriuria.

Antimicrobial susceptibility trends for urinary isolates in the veteran population.

BACKGROUND: Guidance on empiric treatment for urinary tract infections (UTIs) is lacking for the male population which comprises much of the Veteran population in the United States. This study evaluated susceptibility trends in antimicrobials used for treatment of UTIs in the inpatient and outpatient Veteran population nationwide. METHODS: Urine culture data was retrospectively obtained from Corporate Data Warehouse. All urine cultures from Veteran Health Administration patients 18 years of age or older who were treated at any VA health care center in the years 2009 and 2018 were eligible. Antibiograms were constructed for bacterial isolate susceptibility. RESULTS: In 2009 and 2018 isolates from 54,788 and 58,983 Veterans were analyzed, respectively. Escherichia coli was the most common bacteria isolated. For ceftriaxone, E coli susceptibilities were relatively high but trended downward from 2009 to 2018. Common urinary pathogen susceptibilities remained low for fluoroquinolones and trimethoprim-sulfamethoxazole. DISCUSSION: Empiric therapy for Veterans with UTIs should be based on local susceptibility patterns as previously recommended first-line agents have fallen out of favor due to increasing resistance rates. CONCLUSIONS: Both inpatient and outpatient stewardship is needed to ensure appropriate treatment, as viable treatment options for UTIs are becoming increasingly limited.

An Evaluation of Antimicrobial Prophylaxis for Dental Procedures at a Veterans Healthcare System; A Role for Senior Care Pharmacists?

OBJECTIVE: The primary objective of this study was to determine the prevalence of appropriate use of antibiotics before a dental procedure.
DESIGN: Retrospective cohort study.
SETTING: Veterans Healthcare Systems.
PARTICIPANTS: Veterans who filled outpatient prescriptions for antimicrobial dental prophylaxis at the Veterans Administration Western New York Healthcare System from December 1, 2017, through October 1, 2019.
INTERVENTIONS: None.
MAIN OUTCOME MEASURES: Use of antibiotic dental prophylaxis was deemed appropriate if in accordance with guideline recommendations. Descriptive statistics were used to summarize data.
RESULTS: A total of 130 veterans receiving antibiotics for dental prophylaxis were included in this evaluation. Of those who were included, only 16.9% received appropriate antibiotic dental prophylaxis. Patients with a prosthetic joint were significantly more likely to be inappropriately prescribed antibiotics for dental prophylaxis. Approximately 87% of patients who were inappropriately prescribed antibiotic prophylaxis had prosthetic joints (P < .0001).
CONCLUSION: Most antibiotics for dental prophylaxis are prescribed inappropriately. The large amount of inappropriately used antibiotics in this study highlights the need for dental stewardship in our veteran population. Antibiotics for dental prophylaxis therefore represent an important stewardship target in the outpatient setting. This may be an ideal opportunity for senior care pharmacists to intervene upon.
