Impact of a hospital-wide computerised approach to optimise the quality of antimicrobial prescriptions in patients with severe obesity: a quasi-experimental study

Abstract Background Rates of adherence to available recommendations for dose adjustments in patients with severe obesity are generally low. Hence, antimicrobials are often underdosed in these patients. Antimicrobial stewardship programmes can improve the use of antimicrobials in hospitalised patients. The aim of the study was to analyse the impact of an antimicrobial stewardship programme based on a computerised clinical decision support system for optimal dosing and antimicrobial use in inpatients with severe obesity. Methods This quasi-experimental retrospective study using interrupted time series was conducted in an academic centre in Canada from August 2008 to June 2018. The Antimicrobial Prescription Surveillance System was implemented in August 2010 (intervention 1) and specific rules targeting patients with class III obesity (body mass index ≥ 40 kg/m2) were added in June 2014 (intervention 2). Data were collected from all hospitalised adults receiving antimicrobials which required dose adjustment for severe obesity and were stratified by body mass index. Segmented regression analysis of interrupted time series was used to evaluate the impact of the Antimicrobial Prescription Surveillance System on the proportion of inappropriate days of therapy according to posology and on antimicrobial consumption. Results Overall, 65 205 antimicrobial prescriptions (68% non-obese, 25% class I-II obesity, and 7% class III obesity) were analysed. In patients with class III obesity, the intervention was associated with a decrease in the proportion of inappropriate days of therapy (trend after the first intervention, −0.8% per 2-month period [95% CI −1.1 to −0.5], p < 0.001; intercept, 11.3% [95% CI 8.2 to 14.5], p < 0.001), which led to a reduction of 35% over an eight-year period (from pre-intervention level of 19.1%). Intervention 1 resulted in a downward trend in antimicrobial consumption, followed by an increasing trend after intervention 2. In these patients, the most frequent interventions made by pharmacists targeted posology (46%). Conclusions Antimicrobial Prescription Surveillance System had a positive impact on dosing optimisation and antimicrobial consumption in patients with class III obesity. Improving antimicrobial prescriptions in these patients is important because suboptimal dosing could be associated with unfavourable outcomes.

The Impact

Background: Automatic discontinuation of antimicrobial orders after a prespecified duration of therapy has been adopted as a strategy for reducing excess days of therapy (DOT) as part of antimicrobial stewardship efforts. Automatic stop orders have been shown to decrease antimicrobial DOT. However, inadvertent treatment interruptions may occur as a result, potentially contributing to adverse patient outcomes. To evaluate the effects of this practice, we examined the impact of the removal of an electronic 7-day ASO program on hospitalized patients. Methods: We performed a quasi-experimental study on inpatients in 3 acute-care academic hospitals. In the preintervention period (automatic stop orders present; January 1, 2016, to February 28, 2017), we had an electronic dashboard to identify and intervene on unintentionally missed doses. In the postintervention period (April 1, 2017, to March 31, 2018), the automatic stop orders were removed. We compared the primary outcome, DOT per 1,000 patient days (PD) per month, for patients in the automatic stop orders present and absent periods. The Wilcoxon rank-sum test was used to compare median monthly DOT/1,000 PD. Interrupted time series analysis (Prais-Winsten model) was used to compared trends in antibiotic DOT/1,000 PD and the immediate impact of the automatic stop order removal. Manual chart review on a subset of 300 patients, equally divided between the 2 periods, was performed to assess for unintentionally missed doses. Results: In the automatic stop order period, a monthly median of 644.5 antibiotic DOT/1,000 PD were administered, compared to 686.2 DOT/1,000 PD in the period without automatic stop orders (P < .001) (Fig. 1). Using interrupted time series analysis, there was a nonsignificant increase by 46.7 DOT/1,000 PD (95% CI, 40.8 to 134.3) in the month immediately following removal of automatic stop orders (P = .28) (Fig. 2). Even though the slope representing monthly change in DOT/1,000 PD increased in the period without automatic stop orders compared to the period with automatic stop orders, it was not statistically significant (P = .41). Manual chart abstraction revealed that in the period with automatic stop orders, 9 of 150 patients had 17 unintentionally missed days of therapy, whereas none (of 150 patients) in the period without automatic stop orders did. Conclusions: Following removal of the automatic stop orders, there was an overall increase in antibiotic use, although the change in monthly trend of antibiotic use was not significantly different. Even with a dashboard to identify missed doses, there was still a risk of unintentionally missed doses in the period with automatic stop orders. Therefore, this risk should be weighed against the modest difference in antibiotic utilization garnered from automatic stop orders.Funding: NoneDisclosures: None

Abstract Objective: To determine whether cascade reporting is associated with a change in meropenem and fluoroquinolone consumption. Design: A quasi-experimental study was conducted using an interrupted time series to compare antimicrobial consumption before and after the implementation of cascade reporting. Setting: A 399-bed, tertiary-care, Veterans’ Affairs medical center. Participants: Antimicrobial consumption data across 8 inpatient units were extracted from the Center for Disease Control and Prevention (CDC) National Health Safety Network (NHSN) antimicrobial use (AU) module from April 2017 through March 2019, reported as antimicrobial days of therapy (DOT) per 1,000 days present (DP). Intervention: Cascade reporting is a strategy of reporting antimicrobial susceptibility test results in which secondary agents are only reported if an organism is resistant to primary, narrow-spectrum agents. A multidisciplinary team developed cascade reporting algorithms for gram-negative bacteria based on local antibiogram and infectious diseases practice guidelines, aimed at restricting the use of fluoroquinolones and carbapenems. The algorithms were implemented in March 2018. Results: Following the implementation of cascade reporting, mean monthly meropenem (P =.005) and piperacillin/tazobactam (P = .002) consumption decreased and cefepime consumption increased (P < .001). Ciprofloxacin consumption decreased by 2.16 DOT per 1,000 DP per month (SE, 0.25; P < .001). Clostridioides difficile rates did not significantly change. Conclusion: Ciprofloxacin consumption significantly decreased after the implementation of cascade reporting. Mean meropenem consumption decreased after cascade reporting was implemented, but we observed no significant change in the slope of consumption. cascade reporting may be a useful strategy to optimize antimicrobial prescribing.

The Impact

Background: The impact of antimicrobials generic entry (GE) is controversial. Their introduction could provide an economic benefit yet may also increase their consumption, leading to a higher risk of resistance. Our aim was to analyze the impact of GE on trends of antimicrobial consumption in an acute-care hospital. Methods: A retrospective quasi-experimental interrupted time series analysis was conducted at a 400-bed tertiary hospital in Barcelona, Spain. All antimicrobials for systemic use for which a generic product entered the hospital from January 2000 to December 2019 were included. Antimicrobial consumption was expressed as DDD/100 bed days. Results: After GE, the consumption of cefotaxime (0.09, p < 0.001), meropenem (0.54, p < 0.001), and piperacillin-tazobactam (0.13, p < 0.001) increased, whereas the use of clindamycin (−0.03, p < 0.001) and itraconazole (−0.02, p = 0.01) was reduced. An alarming rise in cefepime (0.004), daptomycin (1.02), and cloxacillin (0.05) prescriptions was observed, despite not achieving statistical significance. On the contrary, the use of amoxicillin (−0.07), ampicillin (−0.02), cefixime (−0.06), fluconazole (−0.13), imipenem–cilastatin (−0.50) and levofloxacin (−0.35) decreased. These effects were noticed beyond the first year post GE. Conclusions: GE led to an increase in the consumption of broad-spectrum molecules. The potential economic benefit of generic antibiotics could be diluted by an increase in resistance. Antimicrobial stewardship should continue to monitor these molecules despite GE.

The Impact

Abstract Background To meet the core elements required for antimicrobial stewardship programs, our institution implemented a pharmacy-led antibiotic timeout (ATO) process in 2017 and a multidisciplinary ATO process in 2019. An antibiotic timeout is a discussion and review of the need for ongoing empirical antibiotics 2-4 days after initiation. This study sought to evaluate both the multidisciplinary ATO and the pharmacy-led ATO in a pediatric population, compare the impact of each intervention on antibiotic days of therapy (DOT) to a pre-intervention group without an ATO, and to then compare the impact of the pharmacy-led ATO versus multidisciplinary ATO on antibiotic days of therapy (DOT). Methods This was a retrospective, pre-post, quasi-experimental study of pediatric patients comparing antibiotic DOT prior to ATO implementation (pre-ATO), during the pharmacy-led ATO (pharm-ATO), and during the multidisciplinary ATO (multi-ATO). The pre-ATO group was a patient sample from February-September 2016, prior to the initiation of a formal ATO. The pharmacy-led ATO was implemented from February-September 2018. This was followed by a multidisciplinary ATO led by pediatric residents and nurses from February-September 2019. Both the pharm-ATO and the multi-ATO were implemented as an active non-interruptive alert added to the electronic health record patient list. This alert triggered when new antibiotics had been administered to the patient for 48 hours, at which time, the responsible clinician would discuss the antibiotic and document their decision via the alert workspace. Pediatric patients receiving IV or PO antibiotics administered for at least 48 hours were included. The primary outcome was DOT. Secondary outcomes included length of stay (LOS) and mortality. Results 1284 unique antibiotic orders (n= 572 patients) were reviewed in the pre-ATO group, 868 (n= 323 patients) in the pharm-ATO and 949 (n= 305 patients) in the multi-ATO groups. Average DOT was not significantly different pre vs post intervention for either methodology (Table 1). Mortality was similar between groups, but LOS was longer for both intervention groups (Table 1). Impact of an ATO on DOT, Mortality and LOS Conclusion An ATO had no impact on average antibiotic DOT in a pediatric population, regardless of the ATO methodology.

Abstract Objective: Elevated body mass index (BMI) is associated with multiple chronic conditions including diabetes and cardiovascular disease. Patients with overweight or obesity may also suffer from comorbidities not directly related to the pathophysiology of elevated BMI. The current study sought to determine the impact of BMI and different types of chronic conditions on health-related quality of life (HRQoL) outcomes. Design: Six weight categories by BMI were identified: Underweight, Normal weight, Overweight, Class-I obesity, Class-II obesity, and Class-III obesity. Twenty chronic conditions were considered and categorized as elevated BMI-related (concordant) or -unrelated (discordant) conditions. HRQoL outcomes were measured using Short Form-6 Dimensions (SF-6D). Multivariable regression models were performed to examine the impact of type, number of comorbid conditions, and BMI categories on SF-6D scores. Setting: Medical Expenditure Panel Survey (2013-2015). Participants: Nationally representative sample of US population; 18 years or older (n=58,960). Results: Of the sample, 1.7%, 32.9%, 34.0%, and 31.4% were classified as underweight, normal weight, overweight, and obese, respectively. The SF-6D scores were significantly decreased across all obesity classes, with the largest reduction in Class-III obesity (0.033; p < 0.001). Additionally, individuals with obesity having one or more concordant or discordant comorbidities further reduced SF-6D scores between 0.031 and 0.148 (p-values < 0.001) or between 0.080 and 0.212 (p-values < 0.001), respectively. Conclusions: Individuals with obesity had a significant reduction in HRQoL outcomes compared to those with normal BMI. Importantly, discordant comorbidity resulted in greater reduction in HRQoL outcomes compared to concordant comorbidity in subjects with elevated BMI.

The Impact

This article examines the impact of Phoenix’s light rail system, which opened in 2008, on new firm formation in specific industries. Individual business data from 1990–2014 are used in a quasi-experimental adjusted-interrupted time series (AITS) regression to compare the impact of the transit system’s construction on new business starts in ‘treatment’ and ‘control’ areas before and after the opening of the line. Findings show that the transit adjacency is worth an 88% increase in knowledge sector new starts, a 40% increase in service sector new starts and a 28% increase in retail new starts at the time the system opened, when compared with automobile-accessible control areas. However, the light rail also appears to suffer from a ‘novelty factor’– after the initial increase in new establishment activity in adjacent block groups, the effect diminishes at the rate of 8%, 6% and 7% per year, respectively. The results also provide insight into the spatial extent of light rail impacts to new business formation, with areas 1 mile from stations observing 21% fewer retail new business starts and 12% fewer knowledge sector new starts than areas within a quarter of a mile of stations.

Abstract Background Methicillin-resistant Staphylococcus aureus (MRSA) remains a significant pathogen in patients with respiratory infections. Guidelines recommend empiric MRSA coverage in patients at increased risk, resulting in substantial vancomycin use. Recent literature highlights the use of MRSA nasal assays as a rapid screening tool for MRSA pneumonia, demonstrating high negative predictive values and allowing for shorter empiric coverage. We aimed to evaluate the impact of MRSA nasal screening review by the antimicrobial stewardship program (ASP) on vancomycin utilization for respiratory infections. Methods This was a retrospective, quasi-experimental, pre-post intervention study. The intervention saw the addition of an MRSA screening review tool into the ASP electronic record, highlighting patients on vancomycin (actively or recently administered) with a negative MRSA screening. Vancomycin days of therapy (DOT) was collected for all orders indicated for a respiratory infection in the two weeks following a negative screening. Additional outcomes include vancomycin total dose and DOT per 1,000 patient days. Outcomes were compared via independent samples t-tests. Results 1,110 MRSA screenings resulted across 2 months, of which the majority were excluded for either not having vancomycin ordered, or for having vancomycin ordered for a non-respiratory indication, leaving 37 and 35 evaluable screenings in the pre- and post-intervention groups, respectively. Regarding vancomycin DOT, we did not identify a significant difference between pre- and post-intervention groups with respective means of 2.45 (SD=1.52) and 2.14 (SD=1.12) (p=0.35). We identified a total 8.78 vancomycin DOT per 1,000 patient days in the pre-intervention group versus 6.69 in the post-intervention group. Conclusion ASP-guided review of MRSA screenings was associated with a nonsignificant decrease in mean vancomycin DOT and lower total DOT per 1,000 patient days for respiratory infections following a negative screen. Given the recent implementation of our intervention, our analysis covered a small sample size, highlighting the need for continued data collection. MRSA screenings are not always fully or immediately utilized in our institution, demonstrating room to de-escalate MRSA-targeted antibiotics. Disclosures All Authors: No reported disclosures

Abstract Aims We aimed to determine the effect of increasing body weight upon right ventricular (RV) volumes, energetics, systolic function, and stress responses using cardiovascular magnetic resonance (CMR). Methods and results We first determined the effects of World Health Organization class III obesity [body mass index (BMI) > 40 kg/m2, n = 54] vs. healthy weight (BMI < 25 kg/m2, n = 49) upon RV volumes, energetics and systolic function using CMR. In less severe obesity (BMI 35 ± 5 kg/m2, n = 18) and healthy weight controls (BMI 21 ± 1 kg/m2, n = 9), we next performed CMR before and during dobutamine to evaluate RV stress response. A subgroup undergoing bariatric surgery (n = 37) were rescanned at median 1 year to determine the effects of weight loss. When compared with healthy weight, class III obesity was associated with adverse RV remodelling (17% RV end-diastolic volume increase, P < 0.0001), impaired cardiac energetics (19% phosphocreatine to adenosine triphosphate ratio reduction, P < 0.001), and reduction in RV ejection fraction (by 3%, P = 0.01), which was related to impaired energetics (R = 0.3, P = 0.04). Participants with less severe obesity had impaired RV diastolic filling at rest and blunted RV systolic and diastolic responses to dobutamine compared with healthy weight. Surgical weight loss (34 ± 15 kg weight loss) was associated with improvement in RV end-diastolic volume (by 8%, P = 0.006) and systolic function (by 2%, P = 0.03). Conclusion Increasing body weight is associated with significant alterations in RV volumes, energetic, systolic function, and stress responses. Adverse RV modelling is mitigated with weight loss. Randomized trials are needed to determine whether intentional weight loss improves symptoms and outcomes in patients with obesity and heart failure.

Abstract Objective To assess the impact of gestational weight gain >20 pounds (more than Institute of Medicine [IOM] recommendations) on postpartum infectious morbidity in women with class III obesity. Methods This is a retrospective cohort of term, nonanomalous singleton pregnancies with body mass index ≥40 at a single institution from 2013 to 2017. Pregnancies with multiple gestation, late entry to care, and missing weight gain data are excluded. Primary outcome is a composite of postpartum infection (endometritis, urinary tract, respiratory, and wound infection). Secondary outcomes include components of composite, wound complication, readmission, and blood transfusion. Bivariate statistics compared demographics, pregnancy complications, and delivery characteristics of women exceeding IOM guidelines (GT20) with those who did not (LT20). Regression models were used to estimate adjusted odds of outcomes. Results Of 374 women, 144 (39%) gained GT20 and 230 (62%) gained LT20. Primiparous, nonsmokers more likely gained GT20 (p < 0.05). No significant difference in other demographics. Among women who gained GT20, 10.4% had postpartum infectious morbidity compared with 3.0% in LT20 (p < 0.01). Wound infection is more common in the GT20 group (7.6 vs. 2%, p = 0.02). After adjustment, women who gained GT20 had threefold higher odds of postpartum infectious morbidity (adjusted odds ratio: 3.17, 95% confidence interval: 1.17, 8.60). Conclusion Women with class III obesity who gain more than the IOM recommends are at increased risk for postpartum infectious morbidity.
