Quality Indicators of Antimicrobials Prescribing in Iraq: A Scoping Review

Background: Antimicrobial overconsumption is a global public health concern, particularly in the Middle East, where illnesses and antibiotic use are on the increase. Antimicrobial resistance is associated with excessive usage. As a Middle Eastern country, Iraq provides a suitable baseline for situating it amid its neighbors. We use quality indicators to reliably identify bad practice and recommend updated antibiotic prescribing guidelines for hospitalized patients. Objectives: To compare antimicrobial prescribing quality metrics in Iraqi hospitals to those in Middle Eastern nations. Methods: We conducted a point prevalence survey to assess the inappropriateness of antibiotic usage in the Middle East after evaluating literature from sources such as Scopus, Web of Science, PubMed, and EBSCO. To examine the Iraqi scenario, we used four primary quality indicators: guidelines compliance, stop/review note documentation, parenteral administration, and the selection of specific antibios. According to the study, Iraq's guideline availability ranged from 0% to 7%, which was lower than Jordan's optimum of 95.8%. Results: The rate of stop/review documentation was approximately 0.4%, which was lower than the maximum rate of 72% in the UAE; and only 1.2% of prescriptions were targeted antibiotics, which was higher than Iran's 0%. Regarding parenteral antibiotics, Iraq reported that 89.9% of the antibiotics used were injectable, which is consistent with most comparable nations (74%-100%). Conclusions: In Iraqi hospitals, antimicrobials are used inappropriately. An immediate effort is necessary to update national records, with ongoing follow-up by regular prevalence surveys.

The quality of antimicrobial prescribing in skin and soft tissue management in Australian hospitals: an analysis of the National Antimicrobial Prescribing Survey data

Skin and soft tissue infections (SSTIs) are among the most common indications for antimicrobial prescribing in hospitals. Inappropriate antimicrobial use can lead to increased morbidity, unnecessary hospital re-admission and increased antimicrobial resistance. This study aimed to assess the quality of antimicrobial prescribing practices in SSTI management within Australian hospitals to provide guidance for future practice. A retrospective analysis was conducted with data from the National Antimicrobial Prescribing Survey (NAPS). SSTI prescribing data from Hospital NAPS (2013-2022) and surgical site infection data from Surgical NAPS (2016-2022) datasets were analysed. Variables assessed included guideline compliance, appropriateness as per the structured NAPS algorithm, and reasons for inappropriateness. From the Hospital NAPS dataset, 40,535 antimicrobial prescriptions for SSTIs were analysed. The most common indication was cellulitis (34.1%, N=13,822), and the most prescribed antimicrobial was flucloxacillin (18.8%, N=7,638). SSTI indications had a lower rate of guideline compliance but a higher rate of appropriateness compared with all other indications for antimicrobial prescriptions (guideline compliance 66.3%, N=21,035 vs 67.4%, N=156,285; appropriateness 75.6%, N=30,639 vs 72.7%, N=209,383). The most common reason for inappropriateness was incorrect dose or frequency (29.3%, N=2367). From the Surgical NAPS dataset, 5674 prescriptions for surgical site infections were analysed. Of these, 68.2% (N=3867) were deemed to be appropriate. The most common reason for inappropriateness was incorrect dose or frequency (27.7%, N=350). As SSTIs are a common indication for prescribing an antimicrobial in Australian hospitals, identifying effective antimicrobial stewardship strategies to optimize antimicrobial use for SSTI management is recommended to improve patient outcomes.

Cultivating global antimicrobial stewardship: linguistic and cultural validation of the Australian National Antimicrobial Prescribing Survey appropriateness assessment definitions for Portugal.

Antimicrobial resistance is driven by inappropriate antimicrobial prescribing. The National Antimicrobial Prescribing Survey (NAPS) is an Australian-developed auditing platform to assist in the assessments of antimicrobial quality by antimicrobial stewardship programmes using consensus-based definitions. The NAPS has demonstrated to be transferable to other countries. Its adaptation to Portugal could improve knowledge about the quality of antimicrobial prescribing in the country. To translate, culturally adapt, and validate the Australian Hospital NAPS appropriateness assessment definitions of antimicrobial prescribing for Portugal. International recommendations on translation and adaptation of instruments were followed. Two panels of experts participated in the process, using Zoom® for discussions and interviews, and Google Forms® for assessing vignettes. A native English-speaking person proficient in Portuguese conducted the back-translation. SPSS v.28 and Excel® were used for validity calculation. The Portuguese version was well accepted, its implementation being perceived as desirable and feasible by the experts. Validation process showed a Fleiss' κ score of 0.483 (95% CI, 0.415-0.551, P < 0.005) for appropriateness, and an average agreement with the Australian NAPS team of 0.8 and 0.9, respectively, for appropriateness and reasons for inappropriateness. The Portuguese version of the Australian Hospital NAPS appropriateness assessment definitions of antimicrobial prescribing, the first to be translated from English, was deemed non-inferior to the original, was well accepted, considered to be desirable and feasible, and could inspire other countries, particularly other Portuguese-speaking countries, to adapt and validate them in their own contexts, reinforcing the possibility of transferring NAPS use beyond Australia.

Assessment of antimicrobial prescribing patterns, guidelines compliance, and appropriateness of antimicrobial prescribing in surgical-practice units: point prevalence survey in Malaysian teaching hospitals.

Objectives: This study sought to investigate the quality of antimicrobial prescribing among adult surgical inpatients besides exploring the determinants of non-compliance and inappropriate prescribing to inform stewardship activities. Methods: A cross-sectional point prevalence study employing Hospital National Antimicrobial Prescribing Survey (Hospital NAPS) was conducted in April 2019 at two teaching hospitals in Malaysia. Results: Among 566 surgical inpatients, 44.2% were receiving at least one antimicrobial, for a total of 339 prescriptions. Antimicrobials belonging to the World Health Organization's Watch group were observed in 57.8% of cases. Both hospitals exhibited similar types of antimicrobial treatments prescribed and administration routes. A significant difference in antimicrobial choice was observed between hospitals (p < 0.001). Hospital with electronic prescribing demonstrated better documentation practice (p < 0.001). Guidelines compliance, 32.8% (p = 0.952) and appropriateness, 55.2% (p = 0.561) did not significantly differ. The major contributors of inappropriateness were incorrect duration, (15%) and unnecessary broad-spectrum coverage, (15.6%). Non-compliance and inappropriate prescribing were found to be 2 to 4 times significantly higher with antimicrobial prophylaxis prescription compared to empirical therapy. Conclusion: Antimicrobial stewardship efforts to improve appropriate surgical prescribing are essential. These initiatives should prioritize surgical prophylaxis prescribing, focusing on reducing unnecessarily prolonged use and broad-spectrum antimicrobials, raising awareness among prescribers and promoting proper documentation.

Assessing the quality of antimicrobial prescribing in solid organ transplant recipients: a new frontier in antimicrobial stewardship.

Post-transplant infections remain a leading cause of morbidity and mortality in solid organ transplant recipients (SOTRs) and local standardized antimicrobial treatment guidelines may contribute to improved clinical outcomes. Our study assessed the rate of therapeutic compliance with local standard guidelines in the treatment of common infections in SOTR, and their associated outcomes. Consecutive adult SOTRs admitted to the transplant floor from January-September 2020 and were treated for an infectious syndrome were followed until discharge or for 30 days following the date of diagnosis, whichever was shorter. Data was extracted from electronic medical records. Guideline compliance was characterized as either appropriate, effective but unnecessary, undertreatment, or inappropriate. Nine hundred and thirty-six SOTR were admitted to the transplant ward, of which 328 patients (35%) received treatment for infectious syndromes. Guidelines were applicable to 252 patients, constituting 275 syndromes: 86 pneumonias; 82 urinary tract infections; 40 intra-abdominal infections; 38 bloodstream infections; and 29 C. difficile infections. 200/246 (81%) of infectious syndromes received appropriate or effective but unnecessary empiric treatment. In addition, appropriate tailoring of antimicrobials resulted in a significant difference in 30-day all-cause mortality (adjusted OR of 0.07, 95% CI 0.01-0.38; P = .002). Lastly, we found that guideline-compliant empiric therapy was found to prevent the development of multi-drug resistance in a time-dependent analysis (adjusted HR of 0.21, 95% CI 0.08-0.52; P = .001). Our data show that adherence to locally developed guidelines was associated with reduced mortality and resistant-organism development in our cohort of SOTR.

Metronidazole prescribing practices in Australian hospitals: Measuring guideline compliance and appropriateness to support antimicrobial stewardship

BackgroundMetronidazole is a commonly prescribed antimicrobial in Australian hospitals. Inappropriate use may increase risks to patient care, such as toxicities and antimicrobial resistance. To date, there is limited information on the quality of metronidazole prescriptions to inform antimicrobial stewardship and quality improvement initiatives. This study aims to describe the quality of metronidazole prescribing practices in Australian hospitals. MethodsRetrospective data analysis of the Hospital National Antimicrobial Prescribing Survey (Hospital NAPS). Data were collected by auditors at each participating hospital using a standardised auditing tool. All data from 2013 to 2021 were de-identified and analysed descriptively. Variables included were antimicrobial prescribed, indication, guideline compliance and appropriateness. ResultsMetronidazole was the fifth most prescribed antimicrobial in the Hospital NAPS dataset (2013–2021), accounting for 5.7 % (n = 14,197) of all antimicrobial prescriptions (n = 250,863). The proportion of metronidazole prescriptions declined by 2 % from 2013 to 2021 (p < 0.001). The most common indications were surgical prophylaxis (15.3 %), diverticulitis (9.4 %), aspiration pneumonia (7.3 %). Over half (53.5 %) of metronidazole prescriptions were deemed compliant with prescribing guidelines and 67.8 % were deemed appropriate. These rates were comparatively lower than the overall results of all antimicrobials. The primary documented reason for inappropriateness was that the spectrum was too broad (34.2 %). Surgical prophylaxis had the lowest rates of guideline compliance (53.8 %) and appropriateness (54.3 %). ConclusionsMetronidazole remains widely used in Australian hospitals with suboptimal rates of guideline compliance and appropriateness. A noted area for improvement that we identified was using metronidazole when its spectrum was too broad, possibly when anaerobic therapy is unnecessary. With increasing international adoption of the Hospital NAPS programme, future comparative studies will be critical to identify global trends of antimicrobial prescribing quality. Antimicrobial stewardship (AMS) programmes have proven to be effective in improving prescribing quality and should be considered to specifically target improvements in metronidazole prescribing.

Agreement between pharmacists and physicians on the assessment of appropriateness of antimicrobial prescribing

IntroductionAudits for monitoring the quality of antimicrobial prescribing are a main tool in antimicrobial stewardship programs; however, interobserver reliability has not been conclusively assessed. Our objective was to measure the level of agreement between pharmacists and physicians on the appropriateness of antimicrobials prescribing in hospitals. MethodsA national multicenter, cross-sectional study was conducted of patients who were receiving antimicrobials one day of April 2021. Hospital participation was voluntary, and the study population was randomly selected. Pharmacists and physicians performed a simultaneous, independent assessment of the quality of antimicrobial prescriptions. The observers used an assessment method by which all indicators of the quality of antimicrobial use were considered. Finally, an algorithm was used to rate overall antimicrobial prescribing as appropriate, suboptimal, inappropriate, or not assessable. Gwet's AC1 coefficient was used to assess interobserver agreement. ResultsIn total, 101 hospitals participated, and 411 hospital antimicrobial prescriptions were reviewed. The strength of agreement was moderate regarding the overall quality of prescribing (AC1=0.51; 95%CI=[0.44–0.58]). A very good level of agreement (AC1>0.80) was observed between pharmacists and physicians in all indicators of the quality, except for duration of treatment, rated as good (AC1=0.79; 95%CI=[0.75–0.83]), and registration on the medical record, rated as fair (AC1=0.34; 95%CI=[0.26–0.43]). The agreement was greater in critical care, onco-hematology, and pediatric units than in medical and surgery units. ConclusionsIn this point prevalence study, a moderate level of agreement was observed between pharmacists and physicians in the evaluation of the appropriateness of antimicrobials prescribing in hospitals.

FTP4.1 Compliance With Antimicrobial Prescribing Guideline Recommendations

Abstract Aims Due to concerns regarding the quality of antimicrobial prescribing in the General Surgery department at a District General Hospital, a prospective quality improvement project was undertaken to guide local antimicrobial stewardship. To assess the compliance of the General Surgery department with local antimicrobial prescribing guidelines and policies, and recommendations in the BNF and electronic medicines compendium (EMC). The aim was to evaluate the extent of change in compliance of the General Surgery junior doctors during after intervention. Methodology Prospectively collected data on the patients admitted and started on antimicrobial agents over two 3-week periods under the General Surgery department. Educational interventions were initiated in the interval between the periods of data collection. Results 91 patients were audited in Cycle 1 with a median age of 57 (9-93) years including 36 males and 55 females. Cycle 2 involved 89 patients with a median age of 60 (9-87) with 48 males and 41 females. After intervention, there was an increase in correct prescribing regime (51.6 to 56.2%), correct dose (91.2 to 98.9%), correct frequency (59.3 to 79.8%), and correct duration; when included (78.8 to 83.3%). There was a decrease in the duration being included on the prescription (36.3 to 33.7%). The increases in correct antimicrobial dosing and correct antimicrobial frequency prescriptions were statistically significant at p ≤ 0.05. Conclusion Areas for improvement in the compliance to prescribing guidelines in the department could be influenced successfully through appropriate intervention. The audit highlighted particular areas to be targeted by education.

Assessment of the quality of antimicrobial prescribing among hospitalized patients in a teaching hospital in Ghana: findings and implications

ABSTRACT Objective There is a need to assess the quality of antimicrobial prescribing in hospitals as a first step toward improving future prescribing to reduce antimicrobial resistance (AMR). This is in line with Ghana's National Action Plan. Methods A point prevalence survey of antimicrobial use was undertaken at the adult medical, surgical, and pediatric wards of Tamale Teaching Hospital using the standardized Global Point Prevalence Survey (GPPS) tool. Key target areas include adherence to current guidelines, limiting the prescribing of ‘Watch’ antibiotics with their greater resistance potential, and limiting the prescribing of antibiotics post-operatively to prevent surgical site infections (SSIs). Results Out of 217 patients' medical records assessed, 155 (71.4%) patients were prescribed antimicrobials. The rates were similar among children (73.9%) and adults (70.3%). Most of the antibiotics prescribed were in the WHO ‘Watch’ group (71.0%) followed by those in the ‘Access’ group (29%). Out of the 23 cases indicated for surgical antimicrobial prophylaxis to prevent SSIs, the majority (69.6%) were given doses for more than 1 day, with none receiving a single dose. This needs addressing to reduce AMR and costs. Guideline compliance with the current Ghanaian Standard Treatment Guidelines (GSTG) for managing infections was also low (28.7%). The type of indication was the only independent predictor of guideline compliance (aOR = 0.013 CI 0.001–0.127, p-value = 0.001). Conclusion Given current concerns with antimicrobial prescribing in this hospital, deliberate efforts must be made to improve the appropriateness of prescribing to reduce AMR via targeted antimicrobial stewardship programs.

Antimicrobial Prescribing before and after the Implementation of a Carbapenem-Focused Antimicrobial Stewardship Program in a Greek Tertiary Hospital during the COVID-19 Pandemic.

Irrational use of antimicrobials poses a significant risk for public health by aggravating antimicrobial resistance. The aim of this repeated point prevalence survey (PPS) was to evaluate the impact of a carbapenem-focused antimicrobial stewardship program (ASP) on overall antimicrobial use and quality of antimicrobial prescribing during the COVID-19 pandemic. All adult inpatients in the University Hospital of Heraklion in Greece were audited twice, before and after the implementation of the ASP, in October 2019 and October 2020, respectively. Patient characteristics, indications and diagnoses for antimicrobial administration, antimicrobials prescribed, and compliance with treatment guidelines were recorded. Of 743 adult inpatients on the days of the two surveys, 398 (53.6%) were on antimicrobials for 437 diagnoses. Following implementation of the ASP, there was substantial decrease in the utilization of carbapenems (4.9% of all antibacterials prescribed in the second PPS compared to 10.3% in the first PPS). A significant improvement was observed for all indicators of the quality of antimicrobial prescribing. Our study demonstrated a positive impact of an ASP implementation during the first stages of the COVID-19 pandemic on reducing the use of last-line antimicrobials and improving overall quality of antimicrobial prescribing.

949. Impact of Antimicrobial Stewardship Pharmacist Participation in Pediatric Infectious Diseases Rounds on Prospective Audit and Feedback Recommendations

Abstract Background Prospective audit and feedback (PAF) is a core strategy of antimicrobial stewardship programs (ASPs). To improve communication of PAF recommendations to the inpatient pediatric infectious diseases (ID) consult service, the ASP pharmacists at our hospital were integrated into ID rounds. The purpose of this study was to assess the impact of ASP pharmacy participation in ID rounds on the rate of ASP recommendations. Methods Prior to implementation of the ASP pharmacist rounding service, the ASP pharmacist did not routinely attend rounds or communicate PAF recommendations directly to the ID consult service. Starting 1/3/22, the ASP pharmacists had daily (M-F) in-person discussions with the ID team regarding their patients’ antimicrobials. Audits performed between 1/4/21-12/30/21 and 1/3/22-4/29/22 on patients with an ID consult were included in the non-rounding cohort (NRC) and rounding cohort (RC), respectively. We compared PAF recommendation rates, characteristics, and acceptance rates between the two cohorts. Results There was an increase in PAF recommendation rate in the RC compared to NRC (188/485 [39%] vs 359/1234 [29%], p &amp;lt; 0.001). Antibiotics were the antimicrobial category mostly likely to have a recommendation and the rate of antibiotic PAF recommendations was higher in the RC compared to the NRC (132/341 [39%] vs. 271/934 [29%], p = 0.001) (Table 1). The most common recommendation types in both cohorts were to optimize the antimicrobial dose and antimicrobial discontinuation. Recommendations were more frequently communicated to the ID team in the RC compared to NRC (125/188 [66%] vs. 107/359 [30%], p &amp;lt; 0.001). The recommendation acceptance rate was similar between the two cohorts (159/188 [85%] RC vs. 290/359 [81%] NRC, p = 0.29). CNS: Central nervous system; IV: Intravenous; NRC: Non-rounding cohort; PAF: Prospective audit and feedback; PO: Per os, oral; RC: Rounding cohort; SSTI: Skin and soft tissue infection; UTI: Urinary tract infection. Conclusion Implementation of a pediatric ASP pharmacist rounding service increased the PAF recommendation rate and improved recommendation communication with the pediatric ID consult service. Participation in rounds may better inform ASP pharmacist PAF recommendations. Future studies describing the potential benefit to the ID team by having an ASP pharmacist present on rounds are warranted. ASPs should consider formal integration of ASP pharmacists as part of the ID consult service to further improve the quality of antimicrobial prescribing.

Impact of interactive computerised decision support for hospital antibiotic use (COMPASS): an open-label, cluster-randomised trial in three Swiss hospitals

BackgroundComputerised decision-support systems (CDSSs) for antibiotic stewardship could help to assist physicians in the appropriate prescribing of antibiotics. However, high-quality evidence for their effect on the quantity and quality of antibiotic use remains scarce. The aim of our study was to assess whether a computerised decision support for antimicrobial stewardship combined with feedback on prescribing indicators can reduce antimicrobial prescriptions for adults admitted to hospital.MethodsThe Computerised Antibiotic Stewardship Study (COMPASS) was a multicentre, cluster-randomised, parallel-group, open-label superiority trial that aimed to assess whether a multimodal computerised antibiotic-stewardship intervention is effective in reducing antibiotic use for adults admitted to hospital. After pairwise matching, 24 wards in three Swiss tertiary-care and secondary-care hospitals were randomised (1:1) to the CDSS intervention or to standard antibiotic stewardship measures using an online random sequence generator. The multimodal intervention consisted of a CDSS providing support for choice, duration, and re-evaluation of antimicrobial therapy, and feedback on antimicrobial prescribing quality. The primary outcome was overall systemic antibiotic use measured in days of therapy per admission, using adjusted-hurdle negative-binomial mixed-effects models. The analysis was done by intention to treat and per protocol. The study was registered with ClinicalTrials.gov (identifier NCT03120975).Findings24 clusters (16 at Geneva University Hospitals and eight at Ticino Regional Hospitals) were eligible and randomly assigned to control or intervention between Oct 1, 2018, and Dec 31, 2019. Overall, 4578 (40·2%) of 11 384 admissions received antibiotic therapy in the intervention group and 4142 (42·8%) of 9673 in the control group. The unadjusted overall mean days of therapy per admission was slightly lower in the intervention group than in the control group (3·2 days of therapy per admission, SD 6·2, vs 3·5 days of therapy per admission, SD 6·8; p<0·0001), and was similar among patients receiving antibiotics (7·9 days of therapy per admission, SD 7·6, vs 8·1 days of therapy per admission, SD 8·4; p=0·50). After adjusting for confounders, there was no statistically significant difference between groups for the odds of an admission receiving antibiotics (odds ratio [OR] for intervention vs control 1·12, 95% CI 0·94–1·33). For admissions with antibiotic exposure, days of therapy per admission were also similar (incidence rate ratio 0·98, 95% CI 0·90–1·07). Overall, the CDSS was used at least once in 3466 (75·7%) of 4578 admissions with any antibiotic prescription, but from the first day of antibiotic treatment for only 1602 (58·9%) of 2721 admissions in Geneva. For those for whom the CDSS was not used from the first day, mean time to use of CDSS was 8·9 days. Based on the manual review of 1195 randomly selected charts, transition from intravenous to oral therapy was significantly more frequent in the intervention group after adjusting for confounders (154 [76·6%] of 201 vs 187 [87%] of 215, +10·4%; OR 1·9, 95% CI 1·1–3·3). Consultations by infectious disease specialists were less frequent in the intervention group (388 [13·4%] of 2889) versus the control group (405 [16·9%] of 2390; OR 0·84, 95% CI 0·59–1·25).InterpretationAn integrated multimodal computerised antibiotic stewardship intervention did not significantly reduce overall antibiotic use, the primary outcome of the study. Contributing factors were probably insufficient uptake, a setting with relatively low antibiotic use at baseline, and delays between ward admission and first CDSS use.FundingSwiss National Science Foundation.TranslationsFor the French and Italian translations of the abstract see Supplementary Materials section.

Ophthalmic Antimicrobial Prescribing in Australian Healthcare Facilities.

The National Antimicrobial Prescribing Survey (NAPS) is a web-based, standardized tool, widely adopted in Australian healthcare facilities to assess the reasons for, the quantity of, and the quality of antimicrobial prescribing. It consists of multiple modules tailored towards the needs of a variety of healthcare facilities. Data regarding ophthalmological antimicrobial use from Hospital NAPS, Surgical NAPS, and Aged Care NAPS were analysed. In Hospital NAPS, the most common reasons for inappropriate prescribing were incorrect dose or frequency and incorrect duration. Prolonged duration was also common in Aged Care prescribing: about one quarter of all antimicrobials had been prescribed for greater than 6 months. All three modules found chloramphenicol to be the most prescribed antimicrobial with a high rate of inappropriate prescribing, usually for conjunctivitis.

Beyond consumption: a qualitative investigation of hospital clinician attitudes to receiving feedback on antimicrobial prescribing quality.

Feedback on optimal antimicrobial prescribing to clinicians is an important strategy to ensure antimicrobial stewardship (AMS) in the hospital setting. To explore the perceptions of antimicrobial prescribing feedback among clinicians in acute care. Prospective qualitative design. A large inner-city tertiary referral center in Dublin, Ireland. Clinicians were recruited from the hospital clinician population. A qualitative study was conducted with a purposive sample of multidisciplinary clinicians. Focus groups and semistructured interviews were used to collect data that were analyzed inductively to identify themes. In total, 30 clinicians from medical, surgical, nursing and pharmacy professions participated in the study. We identified 5 themes: (1) antimicrobial consumption perceived as a proxy measure for prescribing quality; (2) lack of connection between antimicrobial prescribing and patient outcomes; (3) relevance and impact of antimicrobial prescribing feedback associated with professional role; (4) attitudes regarding feedback as an AMS strategy; and (5) knowledge regarding AMS, including antimicrobial prescribing quality measures. Focused feedback on antimicrobial prescribing, with clear goals for improvement, could serve as a useful AMS strategy among clinicians in the acute-care setting. The need for further education and training in AMS was also identified.

159. Characterization of Suboptimal Discharge Antimicrobial Prescriptions and Effect of Inpatient Audit and Feedback on Quality of Antimicrobial Prescribing

BackgroundApproximately 30% of children are discharged from the hospital with an antimicrobial prescription; nearly a third of these prescriptions are suboptimal. Although the best approach to antimicrobial stewardship of discharge prescriptions remains uncertain, prospective audit and feedback (PAF) has improved inpatient antimicrobial use. We aimed to identify and characterize suboptimal discharge antimicrobial prescribing and assess the impact of inpatient PAF on the quality of discharge antimicrobial prescribing at a free-standing children’s hospital.MethodsA retrospective review of enteral discharge antimicrobial prescriptions between 12/1/20-5/31/21 and parenteral antimicrobial prescriptions sent to our hospital’s infusion pharmacy between 3/1/21-5/31/21 was performed to determine if suboptimal or not. A prescription was determined to be suboptimal if the antimicrobial choice, dose, frequency, duration, formulation, or indication was not consistent with institutional and/or national guidelines. Data collection included the antimicrobial, indication, and prescribing medical service. Prescriptions were evaluated for a corresponding inpatient PAF for the same drug and indication and then stratified based on inpatient PAF completion.ResultsA total of 1192 discharge prescriptions for 698 unique patients over 834 hospital encounters were reviewed. Overall, 243 (20%) prescriptions were identified as suboptimal; reasons were duration (16%), dose (8%), frequency (5%), or antimicrobial choice, formulation, or route (≤1%). Prescriptions for cephalexin had the highest rate of suboptimal prescribing (80/167, 48%), followed by amoxicillin-clavulanate (89/203, 44%). A corresponding inpatient PAF was identified for 675 (57%) of discharge antimicrobial prescriptions. Inpatient PAF prior to discharge resulted in fewer suboptimal discharge prescriptions for the same antimicrobial (8% vs. 36%, p < 0.001). ConclusionAntimicrobial prescribing at inpatient discharge was suboptimal in 1 of every 5 prescriptions. Inpatient PAF was associated with improved antimicrobial prescribing at hospital discharge. Antimicrobial stewardship programs should continue to explore ways to capture and intervene on antimicrobials prescribed at discharge.Disclosures Hayden T. Schwenk, MD, MPH, Nothing to disclose

Repeated point prevalence survey on antimicrobial use in a university hospital: what have we learned?

To evaluate the quality of antimicrobial prescribing, at the Department of Internal Medicine University Hospital Centre Rijeka, by assessing the necessity for antimicrobial treatment and adherence to the local Guidelines for hospital antimicrobial drug use and to compare results with previously conducted point prevalence surveys (PPSs). A PPS was conducted on 7th May 2019. Demographic and relevant clinical data of each patient receiving systemic antimicrobials were recorded anonymously in a patient-specific form. The appropriateness of antibiotic prescribing was assessed as adherence to the fourth edition of the Guidelines for hospital antimicrobial drug use. One hundred and seventy-one patients were hospitalized at the Department of Internal Medicine; 37.4% (n = 64) of patients received 102 prescriptions for an antimicrobial drug [62.8% (n = 64) of prescriptions were for intravenous and 37.2% (n = 38) for oral administration]. Of these, 52 were treated for an identified existing infection, 5 were treated for an unknown indication and 7 received antibiotics as prophylaxis. The necessity for antimicrobial treatment was unclear in 19.3% (n = 11) of cases. The antimicrobials were prescribed according to the Guidelines in 65.4% (n = 34) of cases. Adherence to the Guidelines when treating lower respiratory tract infections, urinary tract infections and gastrointestinal tract infections was 47.8%, 55.6% and 92.9%, respectively. Our study revealed antibiotic prescription frequency similar to EU/EEA average and high percentage of unjustified antimicrobial treatment introduction. The rate of adherence to the Guidelines was lower than those observed in western countries. The results lay a basis for tailoring antimicrobial stewardship programs/activities.

Assessment of the Appropriateness of Antimicrobial Use in US Hospitals

Hospital antimicrobial consumption data are widely available; however, large-scale assessments of the quality of antimicrobial use in US hospitals are limited. To evaluate the appropriateness of antimicrobial use for hospitalized patients treated for community-acquired pneumonia (CAP) or urinary tract infection (UTI) present at admission or for patients who had received fluoroquinolone or intravenous vancomycin treatment. This cross-sectional study included data from a prevalence survey of hospitalized patients in 10 Emerging Infections Program sites. Random samples of inpatients on hospital survey dates from May 1 to September 30, 2015, were identified. Medical record data were collected for eligible patients with 1 or more of 4 treatment events (CAP, UTI, fluoroquinolone treatment, or vancomycin treatment), which were selected on the basis of common infection types reported and antimicrobials given to patients in the prevalence survey. Data were analyzed from August 1, 2017, to May 31, 2020. Antimicrobial treatment for CAP or UTI or with fluoroquinolones or vancomycin. The percentage of antimicrobial use that was supported by medical record data (including infection signs and symptoms, microbiology test results, and antimicrobial treatment duration) or for which some aspect of use was unsupported. Unsupported antimicrobial use was defined as (1) use of antimicrobials to which the pathogen was not susceptible, use in the absence of documented infection signs or symptoms, or use without supporting microbiologic data; (2) use of antimicrobials that deviated from recommended guidelines; or (3) use that exceeded the recommended duration. Of 12 299 patients, 1566 patients (12.7%) in 192 hospitals were included; the median age was 67 years (interquartile range, 53-79 years), and 864 (55.2%) were female. A total of 219 patients (14.0%) were included in the CAP analysis, 452 (28.9%) in the UTI analysis, 550 (35.1%) in the fluoroquinolone analysis, and 403 (25.7%) in the vancomycin analysis; 58 patients (3.7%) were included in both fluoroquinolone and vancomycin analyses. Overall, treatment was unsupported for 876 of 1566 patients (55.9%; 95% CI, 53.5%-58.4%): 110 of 403 (27.3%) who received vancomycin, 256 of 550 (46.6%) who received fluoroquinolones, 347 of 452 (76.8%) with a diagnosis of UTI, and 174 of 219 (79.5%) with a diagnosis of CAP. Among patients with unsupported treatment, common reasons included excessive duration (103 of 174 patients with CAP [59.2%]) and lack of documented infection signs or symptoms (174 of 347 patients with UTI [50.1%]). The findings suggest that standardized assessments of hospital antimicrobial prescribing quality can be used to estimate the appropriateness of antimicrobial use in large groups of hospitals. These assessments, performed over time, may inform evaluations of the effects of antimicrobial stewardship initiatives nationally.

Effects of coronavirus disease 2019 (COVID-19) pandemic on antimicrobial prevalence and prescribing in a tertiary hospital in Singapore

BackgroundThe deployment of antimicrobial stewardship (AMS) teams to deal with the COVID-19 pandemic can lead to a loss of developed frameworks, best practices and leadership resulting in adverse impact on antimicrobial prescribing and resistance. We aim to investigate effects of reduction in AMS resources during the COVID-19 pandemic on antimicrobial prescribing.MethodsOne of 5 full-time equivalent AMS pharmacists was deployed to support pandemic work and AMS rounds with infectious disease physicians were reduced from 5 to 2 times a week. A survey in acute inpatients was conducted using the Global Point Prevalence Survey methodology in July 2020 and compared with those in 2015 and 2017–2019.ResultsThe prevalence of antimicrobial prescribing (55% in 2015 to 49% in 2019 and 47% in 2020, p = 0.02) and antibacterials (54% in 2015 to 45% in 2019 and 42% in 2020, p < 0.01) have been reducing despite the pandemic. Antimicrobial prescribing in infectious disease wards with suspected or confirmed COVID-19 cases was 29% in 2020. Overall, antimicrobial prescribing quality indicators continued to improve (e.g. reasons in notes, 91% in 2015 to 94% in 2019 and 97% in 2020, p < 0.01) or remained stable (compliance to guideline, 71% in 2015 to 62% in 2019 and 73% in 2020, p = 0.08).ConclusionDuring the COVID-19 pandemic, there was no increase in antimicrobial prescribing and no significant differences in antimicrobial prescribing quality indicators.

From Little Things Big Things Grow: The Development of an Auditing Program to Assess the Quality of Antimicrobial Prescribing

Background: An important aspect of antimicrobial stewardship is the qualitative assessment of antimicrobial prescribing. Owing to lack of standardized tools and resources required to design, conduct and analyze qualitative audits, these assessments are rarely performed. Objective: We designed an audit tool that was appropriate for all Australian hospital types, suited to local user requirements and including an assessment of the appropriateness of antimicrobial prescribing. Methods: In 2011, a pilot survey was conducted in 32 Australian hospitals to assess the usability and generalizability of a qualitative audit tool. The tool was revised to reflect the respondents’ feedback. A second study was performed in 2012 in 85 hospitals. In 2013, following further feedback and refinement, an online auditing tool, the Hospital National Antimicrobial Prescribing Survey (NAPS), was developed. Early audits demonstrated that surgical prophylaxis had the highest rates of inappropriate prescribing. In 2016, the Surgical NAPS was developed to further investigate reasons for this, and the NAPS program was further expanded to audit antimicrobial prescribing practices in Australian aged-care homes (ie, the Aged Care NAPS). Results: Between January 1, 2013, and November 12, 2019, 523 Australian public and private hospitals (53.8%) utilized the Hospital NAPS; 215 (22.1%) have utilized the Surgical NAPS; and 774 of Australian aged-care homes (29.0%) have utilized the Aged Care NAPS. National reporting has identified key target areas for quality improvement initiatives at both local and national levels. The following initiatives have been outlined in 14 public reports: improved documentation; prolonged antimicrobial prophylaxis; compliance with prescribing guidelines; appropriateness of prescribing; access to evidence-based guidelines; and improved microbiology sampling. Conclusions: By utilizing the Plan-Do-Study-Act cycle for healthcare improvement and by involving end users in the design and evaluation, we have created a practical and relevant auditing program to assess both quantitative and qualitative aspects of antimicrobial prescribing in a wide range of settings. This voluntary program is now endorsed by the National Strategy for Antimicrobial Resistance Surveillance, partners with the Antimicrobial Use and Resistance in Australian Surveillance System, and is utilized by facilities to meet mandatory national accreditation standard requirements. With the success of the NAPS program in Australia, it has now been implemented in New Zealand, Canada, Malaysia, Fiji, and Bhutan, with plans for other countries to implement the program soon. Current research is being conducted to expand the program to include audits for family physicians, veterinarians, and remote indigenous communities, and for antifungal use.Disclosures: NoneFunding: None
