1142. Increased Odds of Psychiatric Illness Among Mothers of Infants with Congenital Syphilis

Background

Syphilis can be transmitted mother to child during pregnancy leading to multisystem birth defects if untreated. In Illinois, screening is mandated for pregnant women at first and third trimesters. The University of Illinois Hospital (UIH) serves a vulnerable patient population with a high syphilis prevalence. An understanding of risk factors associated with maternal syphilis infection can guide prevention of congenital syphilis (CS) with early prenatal diagnosis and treatment. The aim of this retrospective case control study is to describe maternal risk factors associated with CS in a clinical setting.

Methods

Using a database used for health department reporting from 2014-2018 at UIH, 106 maternal syphilis diagnoses were identified. Medical records were reviewed for CS infant diagnosis, sociodemographic information, medical history, and potential risk factors, including multiple sex partners, HIV status, drug use, history of incarceration or sex work, and having sex with men who have sex with men (MSM). Cases were matched with controls of pregnant women with syphilis testing that was not indicative of infection.

Results

Of the maternal syphilis diagnoses identified, there were 8 cases in which CS was possible or highly probable, 68 in which CS was less likely or unlikely, and 30 that were lost to follow up. Of the possible and probable infants’ mothers, 38% had a psychiatric illness (6.80 OR, 95% CI 1.06-43.48) and 25% were homeless (12.00 OR, 95% CI 0.94-153.89). Late or scant prenatal care was seen in 75% (4.15 OR, 95% CI 0.72-23.95) and 75% had inadequate syphilis treatment. None were HIV positive or reported incarceration, intravenous drug use, sex work, or having sex with MSM.

Conclusion

Among infants with probable or possible CS, there was a 6.80 increased odds of maternal psychiatric illness compared to those born to mothers not diagnosed with syphilis, which may have complicated prenatal care and delayed diagnosis or treatment. Psychiatric illness outnumbered several other known risk factors; however, these may be less often discussed during clinical encounters. Psychiatric illness history may be a risk factor and means to identify women in the clinical setting who need close follow up and outreach after a prenatal syphilis diagnosis to prevent or mitigate congenital transmission.

Going for the Gold: A Description of the Centers of Excellence Designation by the Infectious Diseases Society of America

Antimicrobial stewardship programs (ASPs) are recommended by the Centers for Disease Control and Prevention and World Health Organization and mandated by the Joint Commission to curb antimicrobial resistance. However, <50% of institutions have optimal ASPs in place. Building on its experience of antimicrobial stewardship (AMS) advocacy, the Infectious Diseases Society of America (IDSA) developed the AMS Centers of Excellence (CoE) program, which will serve as a conduit to share best practices and highlight the standards for other hospitals to achieve in order to advance the field of AMS. A designation of CoE signifies that these institutions deliver high-quality care consistently, serve as the "gold" standard for executing novel AMS principles, and demonstrate commitment to their ASP. Here, we describe the process and purpose of designating institutions as AMS CoEs, provide awareness to clinicians on opportunities available through IDSA with this CoE designation, and discuss the evolution of the program.

Impact of a hospital-wide huddle on device utilisation and infection rates: a community hospital's journey to zero

Background

Device utilisation ratios (DUR) correlate with device-associated complications and rates of infection. We implemented a hospital-wide Daily Interdisciplinary Safety Huddle (DISH) with infection control and device components. The aim of this study was to evaluate the impact of DISH on DURs and rates of infection for indwelling urinary catheters (IUC) and central venous catheters (CVC).

Methods

A quasi-experimental study assessing DURs and rates of infection before and after implementation of DISH. At DISH, usage of IUC and CVC is reported by managers and the infection preventionist reviews indications and plans for removal. Data before and after implementation were compared. Paired T-test was used to assess for differences between both groups.

Results

DISH was successfully implemented at a community hospital. The average DUR for IUC in intensive care unit (ICU) and non-ICU settings was reduced from 0.56 to 0.35 and 0.27 to 0.12, respectively. CVC DUR decreased from 0.29 to 0.26 in the ICU and 0.14 to 0.12 in non-ICU settings. Catheter-associated urinary tract infections (CAUTIs) decreased by 87% and central line-associated bloodstream infections (CLABSIs) by 96%.

Conclusion

DISH was associated with hospital-wide reductions in DUR and device-associated healthcare-associated infections. Reduction of CLABSIs and CAUTIs had estimated cost savings of $688,050. The impact was more profound in non-ICU settings. To our knowledge, an infection prevention hospital-wide safety huddle has not been reported in the literature. DISH increased device removal, accountability and promoted a culture of safety.

Early Infectious Diseases Specialty Intervention Is Associated With Shorter Hospital Stays and Lower Readmission Rates: A Retrospective Cohort Study

Background

Intervention by infectious diseases (ID) physicians improves outcomes for inpatients in Medicare, but patients with other insurance types could fare differently. We assessed whether ID involvement leads to better outcomes among privately insured patients under age 65 years hospitalized with common infections.

Methods

We performed a retrospective analysis of administrative claims data from community hospital and postdischarge ambulatory care. Patients were privately insured individuals less than 65 years old with an acute-care stay in 2014 for selected infections, classed as having early (by day 3) or late (after day 3) ID intervention, or none. Key outcomes were mortality, cost, length of the index stay, readmission rate, mortality, and total cost of care over the first 30 days after discharge.

Results

Patients managed with early ID involvement had shorter length of stay, lower spending, and lower mortality in the index stay than those patients managed without ID involvement. Relative to late, early ID involvement was associated with shorter length of stay and lower cost. Individuals with early ID intervention during hospitalization had fewer readmissions and lower healthcare payments after discharge. Relative to late, those with early ID intervention experienced lower readmission, lower spending, and lower mortality.

Conclusions

Among privately insured patients less than 65 years old, treated in a hospital, early intervention with an ID physician was associated with lower mortality rate and shorter length of stay. Patients who received early ID intervention during their hospital stay were less likely to be readmitted after discharge and had lower total healthcare spending.

A systematic risk-based strategy to select personal protective equipment for infectious diseases

•

Selection of personal protective equipment (PPE) can be systematic and risk-based.

•

Potential exposures are compared with sites susceptible to infection.

•

Facilitates transparent decision-making about personal protective equipment.

•

PPE evaluation includes: donning/doffing/changing, usability, and fit for purpose.

Background

Personal protective equipment (PPE) is a primary strategy to protect health care personnel (HCP) from infectious diseases. When transmission-based PPE ensembles are not appropriate, HCP must recognize the transmission pathway of the disease and anticipate the exposures to select PPE. Because guidance for this process is extremely limited, we proposed a systematic, risk-based approach to the selection and evaluation of PPE ensembles to protect HCP against infectious diseases.

Methods

The approach used in this study included the following 4 steps: (1) job hazard analysis, (2) infectious disease hazard analysis, (3) selection of PPE, and (4) evaluation of selected PPE. Selected PPE should protect HCP from exposure, be usable by HCP, and fit for purpose.

Results

The approach was demonstrated for the activity of intubation of a patient with methicillin-resistant Staphylococcus aureus or Severe Acute Respiratory Syndrome coronavirus. As expected, the approach led to the selection of different ensembles of PPE for these 2 pathogens.

Discussion

A systematic risk-based approach to the selection of PPE will help health care facilities and HCP select PPE when transmission-based precautions are not appropriate. Owing to the complexity of PPE ensemble selection and evaluation, a team with expertise in infectious diseases, occupational health, the health care activity, and related disciplines, such as human factors, should be engaged.

Conclusions

Participation, documentation, and transparency are necessary to ensure the decisions can be communicated, critiqued, and understood by HCP.

757. Impact of a Sepsis Improvement Team with Prospective Audit and Feedback on SEP-1 Core Measure Adherence in an Urban Community Hospital

Background

Adherence to the CMS sepsis core measure (SEP-1) has been a challenge for facilities nationwide. Checklists, electronic medical record (EMR) alerts and order sets have been shown to improve compliance. We implemented a comprehensive SEP-1 guideline with order sets, checklists and EMR alerts at an urban community hospital. Subsequently, a SEP-1 improvement team with an infectious disease physician and a nurse led a prospective audit and feedback (PAF) program to help improve adherence and reduce errors. We seek to understand the impact of PAF on SEP-1 compliance.

Methods

Quasi-experimental pre- and post-intervention study of SEP-1 compliance at a 151-bed urban community hospital from January 2015 to December 2018. PAF intervention was started on July 2017. Cases were reviewed, SEP-1 failures identified, and feedback given to nurses and clinicians involved within 48 hours of admission. Gaps in adherence are identified, education given, and corrective actions taken. SEP-1 adherence before and after PAF implementation was reviewed.

Results

A total of 307 cases met the SEP-1 inclusion criteria. PAF was successfully implemented. There were 169 SEP-1 cases before and 138 after implementation of PAF. The success rate increased from 44% to 52% with PAF (Figure 1). The most common reasons for failure were initial and repeat lactic acid on both groups (Figure 2).

Conclusion

Prospective audit and feedback for SEP-1 improved compliance rates at our facility. Prospective audit can help identify core measure failures early and provide immediate feedback to clinicians, nurses and laboratory personnel. Immediate feedback by the SEP-1 improvement team may help increase SEP-1 awareness, strengthen existing protocols and promote a culture of safety. SEP-1 is a complex core measure that may transition to pay-for-performance. An ID physician-led SEP-1 improvement team with PAF may be an area for future value-based care opportunities for ID physicians.

487. Prevalence of Antimicrobial Resistance in Gram-Negative Bacilli Bloodstream Infections at a Tertiary Teaching Hospital in the Dominican Republic

Background

Bloodstream infections (BSI) with gram-negative bacilli (GNB) are a major cause of morbidity and mortality worldwide. Sepsis due to BSI can carry a mortality rate as high as 40%, with higher mortality in developing nations. Early and appropriate empiric therapeutic selection plays an important role in survival. The rising incidence of antimicrobial resistance (AMR) limits empiric treatment options. Local susceptibility patterns can vary per region, institution or setting. Understanding local AMR may help guide empiric treatment choices. We seek to describe resistance rates for GNB BSI in the Dominican Republic (DR).

Methods

This is a retrospective review of antimicrobial susceptibility patterns from bloodstream infections in a tertiary hospital in the DR. Susceptibility data from all adult inpatient blood cultures were collected from January 1 to December 31, 2017.

Results

A total of 124 blood cultures were reported. The most common organisms were Escherichia coli (43%) and Klebsiella pneumoniae (23%). Fluoroquinolone resistance was present in 70% of E. coli. Phenotypic susceptibility patterns consistent with extended-spectrum β-lactamase (ESBL) producing GNB were present in 46% of isolates. Carbapenem resistance was found in 4 samples and was most common in P. aeruginosa. Susceptibility profile is described on Table 1.

Conclusion

AMR was high in GNB BSIs in the DR. High rates of ESBL render common cephalosporins sub-optimal for empiric treatment. PTZ retains in vitro susceptibilities despite cefepime resistance but clinical efficacy is controversial. CTX-M ESBLs may cause these resistance pattern in vitro. Further studies are needed to determine genetic mechanisms of resistance. Establishing antimicrobial stewardship programs with rapid diagnostic testing that identify mechanisms of resistance may promote judicious use of carbapenems and reduce further the risk of further development of AMR.

2028. A Survey of Antimicrobial Availability, Training, and Antimicrobial Recommendations by Staff in Pharmacies and Non-pharmacy Stores in the Dominican Republic

Background

Antimicrobial resistance (AMR) is a rising global health challenge. Antimicrobial use (AU) is a key factor in the development of AMR, but knowledge gaps remain on AU and dispensation in low- and middle-income countries (LMICs). AU can be purchased without prescriptions in many LMICs and are available in pharmacies and non-pharmacy stores. We seek to describe the availability, training and AU recommendations in pharmacies and non-pharmacy stores in the Dominican Republic (DR).

Methods

We conducted a survey of pharmacies and non-pharmacy stores that dispense antimicrobials from March to April 2019 in randomly selected locations throughout metropolitan Santo Domingo. Data on the availability of antimicrobials and training on AU was obtained. Antimicrobial of choice for common symptoms such as dysuria, throat pain, diarrhea, fever, and cough were queried, and data tabulated. Availability of antimicrobials by phone and online delivery was assessed.

Results

A total of 35 stores were surveyed. Ten pharmacies and 15 nonpharmacy stores agreed to participate. Ten refused and were excluded. Fifty AU recommendations were given in pharmacies and 16 in non-pharmacy stores. The most common type of antimicrobial recommended were aminopenicillins (Figure 1). Staff received prior training on antimicrobials in 70% of pharmacies and 0% of non-pharmacy stores. Antimicrobial recommendations by symptom in pharmacies and non-pharmacy stores are seen in Figure 2 and 3. Antimicrobials are available for phone delivery in 100% of pharmacies and 90% of non-pharmacy stores. No antimicrobials were available via online delivery apps.

Conclusion

Antimicrobials are widely available in the DR without prescriptions and can be purchased in person or via phone delivery. Aminopenicillins are commonly prescribed and may contribute to high rates of ESBL in the DR. Pharmacy staff gave more specific symptom-based recommendations than non-pharmacy staff and commonly had prior training on antibiotic use. In LMICs with easy access to antimicrobials, frontline staff in pharmacies and non-pharmacy stores are gatekeepers for AU and may benefit from further education and training. Further studies on attitudes and perceptions related to antimicrobial use in the community are needed.

2004. Impact of Procalcitonin Roll-out Without Antimicrobial Stewardship Guidance in a Community Hospital Emergency Department

Background

Lower respiratory tract infections (LRTIs) are one of the most common infectious disease-related emergency department (ED) visits in the United States. The ID Society of America and the Agency for Healthcare Research and Quality support the use of procalcitonin (PCT) for antimicrobial stewardship (ASP) in LRTI. Though not widely available, awareness and access to PCT is rising. At our facility, PCT became available in February 2018. The aim of our study is to assess the impact of PCT at an urban community hospital and identify possible targets for ASP interventions.

Methods

Retrospective review of cases from February to August 2018. Cases from the ED were selected for review. Appropriateness of testing was assessed, defined as guideline-based use for cessation of antibiotics in uncomplicated LRTIs without critical illness or immunosuppression. Demographic variables and clinical characteristics, such as, diagnosis, antimicrobial use and PCT levels were obtained.

Results

PCT was ordered 268 times hospital-wide, of which 160 (60%) were in the ED. Ages ranged from 0–90, with an average of 47. Most cases were male (51%). Appropriate testing for LRTI occurred in 33 (29%) cases. Antimicrobials were used in 75% of cases with low (< 0.5) PCT levels (Figure 1). Length of stay (LOS) was higher in groups that received antimicrobials (Figure 2). Testing was not appropriate in 127 cases (71%), with upper respiratory (21%), soft-tissue (17%), genitourinary (15%) and abdominal (13%) infections as the most common reasons for testing. Other diagnosis included alcohol withdrawal, seizures and altered mental status. Cumulative cost of PCT testing was $24000, of which $19050 was not consistent with guidelines.

Conclusion

Clinicians routinely ordered PCT in the ED. Antimicrobials were used for LRTIs despite low PCT levels. This may have contributed to higher LOS and excess antimicrobial use. Unwarranted PCT testing had a cost of $19050. As PCT becomes widely available in hospitals across the United States, education and decision support by ASP to clinicians may be needed to enhance guideline-appropriate evidence-based use of PCT. Targeted ASP interventions in the ED may have cost savings by reducing excess testing, length of stay and improving antimicrobial use.

1059. Impact of a Syndrome-Based Antimicrobial Stewardship Intervention on Anti-Pseudomonal β-Lactam Use, C. difficile Rates and Cost in an Urban Community Hospital

Background

The use of anti-Pseudomonal β-lactam (APBL) agents has significantly increased in the past decade, carrying higher costs and contributing to antimicrobial pressure. Antimicrobial stewardship (ASP) can promote evidence-based antimicrobial selection and mitigate excess APBL use. We implemented a comprehensive ASP with syndrome-based prospective audit and feedback (PAF) at an urban community hospital. The goal of this study is to assess the impact of syndrome-based PAF on APBL use, C. difficile rates and cost.

Methods

ASP with all CDC core elements was implemented at a 151-bed community hospital in October 2017. Syndrome-based guidelines and PAF was established and overseen via direct communication with an ID physician. Days of therapy (DOT), cost and C. difficile rates were assessed 12 months before and after ASP. DOT for APBL and non-APBL utilization was tabulated by unit and paired t-test performed.

Results

Most cases reviewed by PAF (51%) were represented in our syndrome-based treatment guidelines (Figure 1). Soft tissue (33%) and intra-abdominal (24%) infections were the most common syndromes. Change to guideline was the most common PAF intervention (62%) followed by de-escalation (30%). At 12 months, total DOT/1,000 increased (392.5 vs. 404) while the proportion of parenteral antimicrobials used decreased (71% vs. 65%). Antibiotic expenditures decreased by 23%, with a reduction in APBL of 20% and non-APBL of 10% (Table 1). Statistically significant reductions APBL use in non-ICU settings (P = 0.0139) and statistically significant increases in non-APBL in ICU settings occurred (P = 0.0001) (Figure 2 and 3). C difficile rates decreased from 21% (3.27 vs. 2.56).

Conclusion

Syndrome-based PAF was successfully implemented. A reduction in APBL use was seen in non-ICU settings, where evidence-based de-escalation may be more feasible. APBL use remained high in the ICU but was guideline consistent. A rise in non-APBL use also occurred. Certain critical illness syndromes warrant APBLs, but PAF may promote culture-directed and syndrome-specific treatments. ASP increased guideline-based therapy and contributed to decreased broad-spectrum antimicrobial use, antimicrobial expenditures and C difficile rates. Syndrome based PAF can be successfully implemented in community settings.

Environmental Contact and Self-contact Patterns of Healthcare Workers: Implications for Infection Prevention and Control

BACKGROUND

Respiratory viruses on fomites can be transferred to sites susceptible to infection via contact by hands or other fomites.

METHODS

Care for hospitalized patients with viral respiratory infections was observed in the patient room for 3-hour periods at an acute care academic medical center for over a 2 year period. One trained observer recorded the healthcare activities performed, contacts with fomites, and self-contacts made by healthcare workers (HCWs), while another observer recorded fomite contacts of patients during the encounter using predefined checklists.

RESULTS

The surface contacted by HCWs during the majority of visits was the patient (90%). Environmental surfaces contacted by HCWs frequently during healthcare activities included the tray table (48%), bed surface (41%), bed rail (41%), computer station (37%), and intravenous pole (32%). HCWs touched their own torso and mask in 32% and 29% of the visits, respectively. HCWs' self-contacts differed significantly among HCW job roles, with providers and respiratory therapists contacting themselves significantly more times than nurses and nurse technicians (P < .05). When HCWs performed only 1 care activity, there were significant differences in the number of patient contacts and self-contacts that HCWs made during performance of multiple care activities (P < .05).

CONCLUSIONS

HCWs regularly contact environmental surfaces, patients, and themselves while providing care to patients with infectious diseases, varying among care activities and HCW job roles. These contacts may facilitate the transmission of infection to HCWs and susceptible patients.

Experience of Chicagoland acute care hospitals in preparing for Ebola virus disease, 2014-2015

During the 2014-2015 Ebola Virus Disease (EVD) outbreak, hospitals in the United States selected personal protective equipment (PPE) and trained healthcare personnel (HCP) in anticipation of receiving EVD patients. To improve future preparations for high-consequence infectious diseases, it was important to understand factors that affected PPE selection and training in the context of the EVD outbreak. Semistructured interviews were conducted with HCP involved with decision-making during EVD preparations at acute care hospitals in the Chicago, IL area to gather information about the PPE selection and training process. HCP who received training were surveyed about elements of training and their perceived impact and overall experience by email invitation. A total of 28 HCP from 15 hospitals were interviewed, and 55 HCP completed the survey. Factors affecting PPE selection included: changing guidance, vendor supply, performance evaluations, and perceived risk and comfort for HCP. Cost did not affect selection. PPE acquisition challenges were mitigated by: sharing within hospital networks, reusing PPE during training, and improvising with existing PPE stock. Selected PPE ensembles were similar across sites. Training included hands-on activities with trained observers, instructional videos, and simulations/drills, which were felt to increase HCP confidence. Many felt refresher training would be helpful. Hands-on training was perceived to be effective, but there is a need to establish the appropriate frequency of refresher training frequency to maintain competence. Lacking confidence in the CDC guidance, interviewed trainers described turning to other sources of information and developing independent PPE evaluation and selection. Response to emerging and/or high consequence infectious diseases would be enhanced by transparent, risk-based guidance for PPE selection and training that addresses protection level, ease of use, ensembles, and availability.

Personal protective equipment doffing practices of healthcare workers

During the doffing of personal protective equipment (PPE), pathogens can be transferred from the PPE to the bodies of healthcare workers (HCWs), putting HCWs and patients at risk of exposure and infection. PPE doffing practices of HCWs who cared for patients with viral respiratory infections were observed at an acute care hospital from March 2017 to April 2018. A trained observer recorded doffing performance of HCWs inside the patient rooms using a pre-defined checklist based on the Centers for Disease Control and Prevention (CDC) guideline. Doffing practices were observed 162 times during care of 52 patients infected with respiratory viral pathogens. Out of the 52 patients, 30 were in droplet and contact isolation, 21 were in droplet isolation, and 1 was in contact isolation. Overall, 90% of observed doffing was incorrect, with respect to the doffing sequence, doffing technique, or use of appropriate PPE. Common errors were doffing gown from the front, removing face shield of the mask, and touching potentially contaminated surfaces and PPE during doffing. Deviations from the recommended PPE doffing protocol are common and can increase potential for contamination of the HCW's clothing or skin after providing care. There is a clear need to change the approach used to training HCWs in PPE doffing practices.

The Impact of Antibiotic Stewardship Program Resources on Infection Prevention Programs

Doernberg and colleagues describe the role and resourcing of the infectious disease (ID) physician for an effective hospital-based antibiotic stewardship program (ASP). There are similar resource requirements for the ID physician leader in an effective infection prevention (IP) program. This ID physician partnership is supported by professional organizations and predates the imperative of ID physician leadership in ASP. There are regulatory requirements for established IP programs, but they do not specify leadership structure to the same degree as ASP regulations. The Centers for Medicare and Medicaid and The Joint Commission have specified the inclusion of an ID-trained physician leader in ASP, and this has led to the development of curriculum to train more ASP physicians. More robust advocacy may ensure a similar regulatory mandate supporting the participation of ID-trained physicians in IP programs. This may encourage the development of a curriculum to meet the workforce.

Development of High-Level Echinocandin Resistance in a Patient With Recurrent Candida auris Candidemia Secondary to Chronic Candiduria

Objective

Candida auris is a globally emerging pathogen associated with significant mortality. This pathogen frequently is misidentified by traditional biochemical methods and is resistant to commonly used antifungals. The echinocandins currently are recommended as the first-line treatment for C. auris infections. The objective of this work is to demonstrate the challenges associated with C. auris in the real-world setting.

Methods

A 54-year-old male presented to our institution for concerns of sepsis on multiple occasions over a 5-month period. Eleven urine cultures were positive over this timeframe for yeast (9 unidentified Candida isolates and 2 C. lusitaniae isolates). On day 27, the patient developed echinocandin-susceptible candidemia, which was initially identified as C. haemulonii but later accurately identified as C. auris at an outside mycology reference laboratory. Approximately 10 weeks later, the patient had a recurrence of candidemia, this time caused by an echinocandin-resistant C. auris strain.

Results

Genomic DNA sequencing performed at the outside mycology reference laboratory identified a single serine to proline base pair change at position 639 (S639P) in the hotspot 1 region of the FKS1 gene of the echinocandin-resistant strain.

Conclusions

Our experiences highlight 4 major concerns associated with C. auris: misidentification, persistent colonization, infection recurrence despite the receipt of appropriate initial therapy, and development of resistance.

Utilizing the focused conversation method in qualitative public health research: a team-based approach

Background

Qualitative research studies are becoming increasingly necessary to understand the complex challenges in the healthcare setting. Successfully integrating interdisciplinary teams of investigators can be challenging, as investigators inherently view data through their disciplinary lens. Thus, new methods, such as focused conservation, are needed to facilitate qualitative data analysis by interdisciplinary teams. The purpose of this manuscript is to provide a clear description of how we implemented the focused conversation method to facilitate an organized data-driven discussion that responded to our study objectives and ensured participation of our interdisciplinary team. The focused conversation method has not, to our knowledge, been utilized for this purpose to date.

Methods

To better understand the experience of healthcare personnel (HCP) during preparations for the 2014–2015 Ebola Virus Disease (EVD) outbreak, we interviewed HCP who participated in decision making about EVD preparations and training of workers in the use of enhanced personal protective equipment ensembles in the metropolitan Chicagoland area of Illinois to attain a priori research objectives. We identified a systematic method – the focused conversation method – that enabled our interdisciplinary team to interactively contribute to the framing, analysis and interpretation of the data that would enable us to focus on our research objectives.

Results

The focused conversation developed to support our a priori research objective about the training of HCP in preparations included objective, reflective, interpretive and decisional questions. These questions grounded the conversation in the data, while leveraging discipline-specific lenses and professional experience in the analysis and interpretation. Insights from the conversation were reviewed later against interview transcripts to ensure validity. The conversation identified areas for future research directions and deficiencies in the interview instrument.

Conclusions

The focused conversation is an efficient, organized method for analysis of qualitative data by an interdisciplinary team.

Successful Implementation of an Antibiotic Stewardship Program in an Academic Dental Practice

BACKGROUND

Most antibiotic use in the United States occurs in the outpatient setting, and 10% of these prescriptions are generated by dentists. The development of comprehensive antibiotic stewardship programs (ASPs) in the dental setting is nascent, and therefore we describe the implementation of a dental ASP.

METHODS

A collaborative team of dentist, pharmacist, and physician leaders conducted a baseline needs assessment and literature evaluation to identify opportunities to improve antibiotic prescribing by dentists within Illinois' largest oral health care provider for Medicaid recipients. A multimodal intervention was implemented that included patient and provider education, clinical guideline development, and an assessment of the antibiotic prescribing rate per urgent care visit before and after the educational interventions.

RESULTS

We identified multiple needs, including standardization of antibiotic prescribing practices for patients with acute oral infections in the urgent care clinics. A 72.9% decrease in antibiotic prescribing was observed in urgent care visits after implementation of our multimodal intervention (preintervention urgent care prescribing rate, 8.5% [24/283]; postintervention, 2.3% [8/352]; P < .001).

CONCLUSIONS

We report the successful implementation of a dental ASP that is concordant with the Centers for Disease Control and Prevention Core Elements of Antibiotic Stewardship in the Outpatient Setting. Our approach may be adapted to other dental practices to improve antibiotic prescribing.

1815. Effects of Syndrome-Based Antimicrobial Stewardship Prospective Audit and Feedback Interventions on Antimicrobial Use in an Urban Community Hospital

Background

Establishing antimicrobial stewardship programs (ASP) in community hospitals with limited resources can be challenging. Many hospitals do not have infectious disease (ID) trained pharmacists (PharmD) available. We implemented a comprehensive ASP with syndrome-based prospective audit and feedback at an urban community hospital.

Methods

ASP was implemented at a 151-bed urban community hospital in October 2017. PharmD training on syndrome-based treatment guidelines, including definitions, severity, empiric regimens, de-escalation, and duration was created. Prospective audit by PharmDs was established. This program was implemented and overseen by an ID physician. Days of therapy per 1,000 patient-days (DOT/1,000) was assessed 3 months before and after ASP. Prospective audit and feedback data were reviewed.

Results

At 3 months, antimicrobial use decreased (370 vs. 350 DOT/1,000) while the proportion of oral antimicrobials used increased (32% vs. 43%). Antibiotic expenditures decreased by 11% ($42,500 vs. $37,900). Most cases reviewed by prospective audit (58%) fit pre-determined syndromes (Figure 1). Soft tissue and urinary tract infections were the most common syndromes. Interventions occurred in 53% of cases. De-escalation from broad-spectrum agents was more successful in noncritical care settings (Figure 2).

Conclusion

Syndrome-based prospective audit and feedback was successfully implemented in an urban community hospital with non-ID trained PharmDs using ID physician leadership. Our program led to a decrease in antibiotic use, increase use of oral alternatives, and decreased antibiotic expenditures. Empiric use of broad-spectrum agents was common at our facility. ASP likely contributed to an increase in ceftriaxone and decrease in piperacillin–tazobactam use in medical-surgical floors. Stewardship in critically ill patients remains a challenge. Clear guidelines and access to an ID physician are necessary to provide adequate support for PharmDs without ID-specific training and can help curb antibiotic use. Expanding the list of syndromes may further impact antimicrobial use.

2111. Changing the Culture: A Quasi-Experimental Study Assessing the Burden of Urine Cultures and the Impact of Stewardship of Testing in an Urban Community Hospital

Background

Indwelling urinary catheters (IUC) may cause inflammation and colonization, decreasing the diagnostic yield of urinalysis and urine cultures (UC). Indiscriminate testing can lead to misinterpretation of positive results as a catheter associated urinary tract infection (CAUTI), increasing antibiotic use and CAUTI rates. We studied the burden of UC and implemented a UC stewardship initiative (UCSI) as part of a comprehensive CAUTI reduction program.

Methods

A retrospective review of cases with IUC and positive UC in 2014 was performed. UCSI was implemented in March 2017 (Figure 1). Nursing staff were instructed to contact the infectious diseases physician when UC from IUC were ordered. Cases were reviewed and, if no UC indication based on IDSA guidelines was met, cultures were discontinued after conferring with ordering physician. Twelve months pre- and post-intervention data were collected; including case description, catheter days, UC ordered, alternative cause of fever, and recommendations.

Results

The pre-USCI cohort had 23 UC in 19 cases. One UC (4%) met indication (Figure 2). Three (16%) met NHSN criteria for CAUTI and did not meet UC indication. The USCI cohort had 21 UC orders in 13 cases. Most UC did not meet indication and were cancelled (90%, 19/21). Alternative causes for fever were found in all cases with cancelled UC orders (19/19), including pneumonitis, pneumonia, pancreatitis and tuberculosis. Antimicrobials were used in 53% (7/13). UC orders per hospitalization ranged 1–4 (average 1.7). IUC days ranged from 3 to 18 days (average 8). In both cohorts, UC with indication (3) did not meet NHSN criteria for CAUTI and did not receive antimicrobials.

Conclusion

Patients with IUC frequently underwent UC without evidence-based indications. This may lead clinicians down the wrong diagnostic path and contribute to antimicrobial use. Critically ill patients with inflammatory conditions are at high risk of UC testing. USCI is a cost-effective intervention that reduced indiscriminate testing, antibiotic use and CAUTIs. USCI can play an important role in CAUTI prevention strategies and antibiotic stewardship programs.
