Design We introduced a long-term care facility (LTCF) Infectious Disease (ID) consult service (LID) that provides on-site consultations to residents of a VA LTCF. We determined the impact of the LID service on antimicrobial use and Clostridium difficile infections at the LTCF. Setting A 160-bed Veterans Affairs (VA) LTCF. Methods Systemic antimicrobial use and the rate of positive C. difficile tests at the LTCF were compared for 36 months before and 18 months after the initiation of the ID consultation service using segmented regression analysis of an interrupted time-series. Results In contrast to the pre-intervention period, total systemic antibiotic administration decreased by 30% (P <.001) with a significant reduction in both oral (32%; P<.001) and intravenous agents (25%; P =.008). The greatest reductions were seen for tetracyclines (64%, P <.001), clindamycin (61%; P <.001), sulfamethoxazole/trimethoprim (38%; P <.001), fluoroquinolones (38%; P <.001) and beta-lactam/beta-lactamase inhibitor combinations (28%; P <.001). Rates of change for positive C. difficile tests at the LTCF declined in the post- vs. preintervention periods (P = .04). Conclusions Implementation of a LTCF ID service led to a significant reduction in total antimicrobial use. Bringing providers with infectious disease expertise to the LTCF represents a new and effective means to achieve antimicrobial stewardship.

The Eating Behavior Inventory (EBI) is a self-report instrument for assessing behaviors that have been theoretically implicated in weight loss, e.g., selfmonitoring of food intake and of weight, refusing offers of food, eating at only one place, shopping from a list, eating in response to emotions. Thirty items were constructed in the form of first-person statements, e.g., "1eat in the middle of the night. "Each item was to be rated with a 5-point scale according to how often it was true for the respondent. 1terns were scored such that higher scores always reflected more "appropriate" (theoretically facilitative of weight control) eating patterns. Validity of individual items and total score was assessed in four studies. Twenty-six of the original items appeared valid and were retained. The resulting total score demonstrated validity in these studies and in two crossvalidational comparisons. Internal consistency as measured by split-half reliability and correlations of item scores with total score was acceptable. One month test-retest reliability of item and total scores was satisfactory. Clinical and research applications of the EBl are discussed. 123 0 1 6 4 -0 3 0 5 / 7 9 / 0 6 0 0 -0 1 2 3 5 0 3 . 0 0 / 0 © 1979 Plenum Publishing Corporation

BACKGROUND/OBJECTIVE Antimicrobials are frequently prescribed in long-term care facilities (LTCFs). In order to develop effective stewardship interventions, there is a need for data on current patterns of unnecessary antimicrobial prescribing among LTCF residents. The objective of this study was to examine the frequency of, reasons for, and adverse effects of unnecessary antimicrobial use in our Veterans Affairs (VA) LTCF. DESIGN Retrospective chart review. SETTING Cleveland VA Medical Center LTCF. PARTICIPANTS Randomly selected patients receiving antimicrobial therapy from October 1, 2008 to March 31, 2009. MEASUREMENTS Days of necessary and unnecessary antimicrobial therapy determined using Infectious Diseases Society of America guidelines, syndromes treated with unnecessary antimicrobials, and the frequency of development of Clostridium difficile infection (CDI), colonization or infection with antimicrobial resistant pathogens, and other adverse effects. RESULTS Of 1351 days of therapy prescribed in 100 regimens, 575 days (42.5%) were deemed unnecessary. Of the 575 unnecessary days of therapy, 334 (58%) were for antimicrobial regimens that were entirely unnecessary (n=42). Asymptomatic bacteriuria was the most common reason for entirely unnecessary regimens (n=21), resulting in 173 days of unnecessary therapy. Regimens that were partially unnecessary resulted in 241 (42%) days of unnecessary therapy, with longer than recommended treatment duration accounting for 226 (94%) unnecessary days of therapy. Within 30 days of completing the antimicrobial regimens, 5 patients developed CDI, 5 had colonization or infection with antimicrobial-resistant pathogens, and 10 experienced other adverse drug events. CONCLUSIONS In our VA LTCF, 43% of all days of antimicrobial therapy were unnecessary. Our findings suggest that antimicrobial stewardship interventions in LTCFs should focus on improving adherence to recommended treatment durations and eliminating inappropriate treatment of asymptomatic bacteriuria.
