Pharmacist-led antimicrobial stewardship program in an urgent care setting

European society of clinical microbiology and infectious diseases guidelines for antimicrobial stewardship in emergency departments (endorsed by European association of hospital pharmacists)

SCOPE

This European Society of Clinical Microbiology and Infectious Diseases guideline provides evidence-based recommendations to support a selection of appropriate antibiotic use practices for patients seen in the emergency department (ED) and guidance for their implementation. The topics addressed in this guideline are (a) Do biomarkers or rapid pathogen tests improve antibiotic prescribing and/or clinical outcomes? (b) Does taking blood cultures in common infectious syndromes improve antibiotic prescribing and/or clinical outcomes? (c) Does watchful waiting without antibacterial therapy or with delayed antibiotic prescribing reduce antibiotic prescribing without worsening clinical outcomes in patients with specific infectious syndromes? (d) Do structured culture follow-up programs in patients discharged from the ED with cultures pending improve antibiotic prescribing?

METHODS

An expert panel was convened by European Society of Clinical Microbiology and Infectious Diseases and the guideline chair. The panel selected in consensus the four most relevant antimicrobial stewardship topics according to pre-defined relevance criteria. For each main question for the four topics, a systematic review was performed, including randomized controlled trials and observational studies. Both clinical outcomes and stewardship process outcomes related to antibiotic use were deemed relevant. The literature searches were conducted between May 2021 and March 2022. In April 2022, the panel members were formally asked to suggest additional studies that were not identified in the initial searches. Data were summarized in a meta-analysis if possible or otherwise summarized narratively. The certainty of the evidence was classified according to the Grading of Recommendations Assessment, Development and Evaluation criteria. The guideline panel reviewed the evidence per topic critically appraising the evidence and formulated recommendations through a consensus-based process. The strength of the recommendations was classified as strong or weak. To substantiate the implementation process, implementation trials or observational studies describing facilitators/barriers for implementation were identified from the same searches and were summarized narratively.

RECOMMENDATIONS

The recommendations on the use of biomarkers and rapid pathogen diagnostic tests focus on the initiation of antibiotics in patients admitted through the ED. Their effect on the discontinuation or de-escalation of antibiotics during hospital stay was not reported, neither was their effect on hospital infection prevention and control practices. The recommendations on watchful waiting (i.e. withholding antibiotics with some form of follow-up) focus on specific infectious syndromes for which the primary care literature was also included. The recommendations on blood cultures focus on the indication in three common infectious syndromes in the ED explicitly excluding patients with sepsis or septic shock. Most recommendations are based on very low and low certainty of evidence, leading to weak recommendations or, when no evidence was available, to best practice statements. Implementation of these recommendations needs to be adapted to the specific settings and circumstances of the ED. The scarcity of high-quality studies in the area of antimicrobial stewardship in the ED highlights the need for future research in this field.

Antibiotic stewardship in the emergency department setting: Focus on oral antibiotic selection for adults with skin and soft tissue infections

PURPOSE

An advisory panel of experts was convened by the ASHP Foundation as a part of its Medication-Use Evaluation Resources initiative to provide commentary on an approach to antibiotic stewardship in the treatment of skin and soft tissue infections (SSTIs), with a focus on oral antibiotics in the emergency department (ED) setting for patients who will be treated as outpatients. Considerations include a need to update existing guidelines to reflect new antibiotics and susceptibility patterns, patient-specific criteria impacting antibiotic selection, and logistics unique to the ED setting.

SUMMARY

While national guidelines serve as the gold standard on which to base SSTI treatment decisions, our advisory panel stressed that institutional guidelines must be regularly updated and grounded in local antimicrobial resistance patterns, patient-specific factors, and logistical considerations. Convening a team of experts locally to establish institution-specific guidelines as part of a comprehensive antibiotic stewardship program can ensure patients receive the most appropriate oral therapy for the outpatient treatment of SSTIs in patients visiting the ED.

CONCLUSION

SSTI treatment considerations for antibiotic selection in the ED supported by current, evidence-based guidelines, including guidance on optimal oral antibiotic selection for patients discharged for outpatient treatment, are a useful tool to improve the quality and efficiency of care, enhance patient-centric outcomes and satisfaction, decrease healthcare costs, and reduce overuse of antibiotics.

"The Impact of Pharmacists Engaged in Collaborative Practice Agreements in the United States"

PURPOSE

To evaluate the role and impact of pharmacists in collaborative practice agreements (CPAs) in the United States.

METHODS

An electronic literature review was conducted on studies addressing pharmacists' involvement in CPAs. Articles included in the review were peer-reviewed studies conducted on adults and published between 2017 and 2022. Articles investigating children were excluded.

RESULTS

Of the articles identified, 8 studies met the eligibility criteria and were selected for the literature review. All of the studies were published between 2017 and 2022 in English in the United States. CPAs were already in place in 7 of the studies with variances due to different healthcare settings and patient populations. The studies evaluated the effect of pharmacist engagement in CPAs on the attainment of clinical and financial goals, satisfaction with pharmacist involvement, and existing barriers to pharmacist engagement in CPAs. Findings showed that pharmacist engagement in CPAs had a positive impact on the attainment of the desired clinical and financial goals, and providers were satisfied with pharmacist involvement. A common barrier to pharmacist involvement was the lack of reimbursement.

CONCLUSION

Pharmacists engaged in CPAs have a positive impact on healthcare, and there are opportunities for expansion of pharmacists' roles in CPAs, particularly in non-traditional settings.

Antimicrobial Stewardship at Transitions of Care

Antimicrobial stewardship interventions have historically been siloed in different care settings; recently, a need for stewardship interventions at care transitions has arisen as inappropriate prescribing at care transitions may result in patient harm. There are several care areas that should be considered for optimizing antibiotic prescribing. Interventions can be difficult to implement as they often require the efforts of a multidisciplinary team and are resource intensive. Antimicrobial stewardship programs should prioritize interventions at transitions of care to improve prescribing and patient outcomes.

The Role of Clinical Pharmacists in Antimicrobial Stewardship Programs (ASPs): A Systematic Review

Antimicrobial resistance (AMR) is a major global health threat, increasing deaths and healthcare costs. Antimicrobial stewardship programs (ASPs) have been implemented to optimize antibiotic use and curb resistance. This systematic review aimed to summarize evidence on the role and impact of pharmacists in hospital ASPs. A comprehensive literature search was conducted across databases to identify relevant studies published from 2016 to 2023. Twenty-four studies met the inclusion criteria, comprising global observational and randomized clinical trials. Pharmacists performed various stewardship activities, including prospective audits, formulary management, de-escalation, guideline development, and education. Pharmacist-led interventions significantly improved antibiotic prescribing, reduced unnecessary antibiotic use, optimized therapy, and enhanced outcomes. Multiple studies found that pharmacist reviews decreased the time to optimal antibiotics and improved guideline compliance without affecting readmissions or revisits. De-escalation programs safely reduced antibiotic duration and length of stay. Acceptance rates for recommendations were high. Pharmacist stewardship curbed overall antibiotic use, costs, and duration across hospital departments, leading to savings. While most studies showed positive impacts, fewer detected significant changes in resistance or mortality over short periods. More research is needed, but current evidence demonstrates that pharmacists play critical roles in ASPs, leading to improved antibiotic use and patient outcomes. These findings support integrating pharmacists into stewardship activities, significantly extending programs to ambulatory settings.

Feasibility evaluation to expand a collaborative practice agreement and discontinue antibiotics after an emergency department or urgent care visit

PURPOSE

The impact of pharmacist-led culture follow-up programs for positive cultures is well established. The benefits and feasibility of evaluating negative cultures and deprescribing unnecessary antibiotics after emergency department (ED) and urgent care (UC) visits are unknown; therefore, this evaluation characterized the burden of negative urine cultures and chlamydia tests and estimated how many potential antibiotic days could be saved with deprescribing.

METHODS

This retrospective, descriptive study evaluated patients discharged from an ED or UC location with a pharmacist-led culture follow-up program. The primary objective was to characterize the proportion of patients with a negative urine culture or chlamydia test where an opportunity would exist to deprescribe antibiotics at follow-up. Secondary endpoints included estimating the number of potential antibiotic days that could be saved, postvisit healthcare utilization, and documented adverse drug reactions (ADRs).

RESULTS

For a 1-month period, pharmacists reviewed 398 cultures, of which 208 (52%) were urine cultures or chlamydia tests with negative results. Fifty patients (24%) with negative results had been prescribed empiric antibiotics. The median duration of antibiotic treatment was 7 days (interquartile range [IQR], 5-7 days), while the median time to culture finalization was 2 days (IQR, 1-2 days). There was an opportunity to save a median of 5 antibiotic days per patient. Thirty-two patients (15.3%) followed up with their primary care physician within 7 days; of these patients, 1 (0.05%) had their antibiotic prescription discontinued by the primary care physician. There were no documented ADRs.

CONCLUSION

Expansion of pharmacist-led culture follow-up programs to deprescribe antibiotics for patients with negative cultures has the potential to save significant antibiotic exposure.

A multimodal intervention to decrease inappropriate outpatient antibiotic prescribing for upper respiratory tract infections in a large integrated healthcare system

OBJECTIVE

To evaluate the effectiveness of Carolinas Healthcare Outpatient Antimicrobial Stewardship Empowerment Network (CHOSEN), a multicomponent outpatient stewardship program to reduce inappropriate antibiotic prescribing for upper respiratory infections by 20% over 2 years.

DESIGN

Before-and-after interrupted time series of antibiotics prescribed between 2 periods: April 2016-October 2017 and May 2018-March 2020.

SETTING

The study included 162 primary-care practices within a large healthcare system in the greater Charlotte, North Carolina region.

PARTICIPANTS

Adult and pediatric patients with encounters for upper respiratory infections for which an antibiotic is inappropriate.

METHODS

Patient and provider educational materials, along with a web-based provider prescribing dashboard aimed at reducing inappropriate antibiotic prescribing were developed and distributed. Monthly antibiotic prescribing rates were calculated as the number of eligible encounters with an antibiotic prescribed divided by the total number of eligible encounters. A segmented regression analysis compared monthly antibiotic prescribing rates before versus after CHOSEN implementation, while also accounting for practice type and seasonal trends in prescribing.

RESULTS

Overall, 286,580 antibiotics were prescribed during 704,248 preintervention encounters and 277,177 during 832,200 intervention encounters. Significant reductions in inappropriate prescribing rates were observed in all outpatient specialties: family medicine (relative difference before and after the intervention, -20.4%), internal medicine (-19.5%), pediatric medicine (-17.2%), and urgent care (-16.6%).

CONCLUSIONS

A robust multimodal intervention that combined a provider prescribing dashboard with a targeted education campaign demonstrated significant decreases in inappropriate outpatient antibiotic prescribing for upper respiratory tract infections in a large integrated ambulatory network.

Levels of agreement among clinical pharmacists on the impact of pharmaceutical interventions in Oman: A retrospective analysis

Objectives

Disagreement between health care providers on medication-related interventions can affect clinical outcomes. We aimed to study the outcomes and significance of clinical pharmacists' interventions and evaluate the levels of agreement between different clinical pharmacists on the impact of pharmaceutical interventions.

Methodology

A retrospective study was conducted at a tertiary care hospital in Oman. The study included all documented interventions by clinical pharmacists for all categories of admitted patients that met the inclusion criteria.

Results

The originator clinical pharmacists interjected to improve the efficacy of treatment in (58%, n=1740) of the interventions, followed by toxicity reduction (24%). The level of agreement in the clinical significance resulted in substantial Scotts' kappa (k) between the originator and the first reviewer, the first and second reviewers, and the second reviewer and supervisor (86%; k=0.77; P<.001), (77%; k=0.63; P<.001), (84%; k=0.77; P<.001), respectively. In terms of grading of clinical significance, the originator clinical pharmacists recorded moderate significance in 50% of the interventions, followed by major (30%), not applicable (8.4%), and minor (7.3%). The level of agreement in the clinical significance resulted in substantial Scotts' k between the originator and the first reviewer, and between the second reviewer and supervisor (82%; k=0.72; P<.001), (84%; k=0.77; P<.001), respectively. The level of agreement between the first and second reviewer was fair (55%; k=0.28; p<0.001).

Conclusion

Clinical pharmacists' interventions have a crucial impact on patient safety, improving efficacy and reducing toxicities. Overall, there was a substantial agreement among clinical pharmacists on the clinical significance and grading of the interventions..

Pharmacist-led antimicrobial stewardship programme in a small hospital without infectious diseases physicians

Pharmacists may be tasked to lead antibiotic stewardship programmes (ASP) implementation in small hospitals in absence of infectious diseases (ID) physicians. The objectives are to evaluate the effectiveness of a pharmacist-led ASP in a hospital without ID physician support, with special focus on indicators of the hospital use of antimicrobial agents based on consumption and asess the potential clinical and economic impact of pharmacist interventions (PIs) through the CLEO tool. A prospective quasi-experimental study to implement an ASP in a 194-bed hospital. We evaluated changes in antimicrobial use measured as mean defined daily doses per 1000 patient-days (AUD) for intervention versus preintervention period. A total of 847 antimicrobial PIs were proposed, being 88.3% accepted. Discontinuation due to excessive duration was the most frequently performed PI (23.4%). Most of PIs was classified as major or moderate clinical impact, 41.7% and 37.8% respectively. The global consumption of antimicrobial was reduced from 907.1 to 693.8 AUD, with a signifcant drop in carbapenems and quinolones. Direct expenditure of antibiotics decreased significantly. Pharmacist-led ASP has being effective in reducing consumption of antibiotics. In the absence of ID physician´s support and oversight, pharmacists could lead the improvement of the use of antimicrobials.

A Systematic Review of Pharmacist-Led Antimicrobial Stewardship Programs in Sub-Saharan Africa

BACKGROUND

The misuse of antibiotics contributes significantly to antimicrobial resistance (AMR). Higher treatment costs, longer hospital stays, and clinical failure can all result from AMR. According to projections, Africa and Asia will bear the heaviest burden of AMR-related mortalities in the coming years. Antimicrobial stewardship (AMS) programmes are therefore critical in mitigating the effects of AMR. Pharmacists may play an important role in such programmes, as seen in Europe and North America, but the impact, challenges, and opportunities of pharmacist-led antimicrobial stewardship interventions in Sub-Saharan African hospitals are unknown. The purpose of this systematic review was to assess the impact, challenges, and opportunities of pharmacist-led antimicrobial stewardship interventions in Sub-Saharan African hospitals.

METHODS

The Joanna Briggs Institute (JBI) guidelines were used to search for peer-reviewed pharmacist-led studies based in hospitals in Sub-Saharan Africa that were published in English between January 2015 and January 2021. The PubMed, Embase, and Ovid databases were used.

RESULTS

Education and training, audits and feedback, protocol development, and ward rounds were identified as primary components of pharmacist-led antimicrobial stewardship interventions in Sub-Saharan Africa. The pharmacist-led antimicrobial interventions improved adherence to guidelines and reduced inappropriate prescribing, but were hampered by a lack of laboratory and technological support, limited stewardship time, poor documentation, and a lack of guidelines and policies. Funding, mentorship, guidelines, accountability, continuous monitoring, feedback, multidisciplinary engagements, and collaborations were identified as critical in the implementation of pharmacist-led antimicrobial stewardship programmes.

CONCLUSIONS

These findings suggest that pharmacists in Sub-Saharan African hospitals can successfully lead antimicrobial stewardship programmes but their implementation is limited by lack of mentorship, accountability, continuous monitoring, feedback, collaborations, and poor funding.

Changes in outpatient antibiotic prescribing for acute respiratory illnesses, 2011 to 2018

Objectives:

To describe acute respiratory illnesses (ARI) visits and antibiotic prescriptions in 2011 and 2018 across outpatient settings to evaluate progress in reducing unnecessary antibiotic prescribing for ARIs.

Design:

Cross-sectional study.

Setting and patients:

Outpatient medical and pharmacy claims captured in the IBM MarketScan commercial database, a national convenience sample of privately insured individuals aged <65 years.

Methods:

We calculated the annual number of ARI visits and visits with oral antibiotic prescriptions per 1,000 enrollees overall and by age category, sex, and setting in 2011 and 2018. We compared these and calculated prevalence rate ratios (PRRs). We adapted existing tiered-diagnosis methodology for International Classification of Diseases, Tenth Revision, Clinical Modification (ICD-10-CM) codes.

Results:

In our study population, there were 829 ARI visits per 1,000 enrollees in 2011 compared with 760 ARI visits per 1,000 enrollees in 2018. In 2011, 39.3% of ARI visits were associated with ≥1 oral antibiotic prescription versus 36.2% in 2018. In 2018 compared with 2011, overall ARI visits decreased 8% (PRR, 0.92; 99.99% confidence interval [CI], 0.92–0.92), whereas visits with antibiotic prescriptions decreased 16% (PRR, 0.84; 99.99% CI, 0.84–0.85). Visits for antibiotic-inappropriate ARIs decreased by 9% (PRR, 0.91; 99.99% CI, 0.91–0.92), and visits with antibiotic prescriptions for these conditions decreased by 32% (PRR, 0.68; 99.99% CI, 0.67–0.68) from 2011 to 2018.

Conclusions:

Both the rate of antibiotic prescriptions per 1,000 enrollees and the percentage of visits with antibiotic prescriptions decreased modestly from 2011 to 2018 in our study population. These decreases were greatest for antibiotic-inappropriate ARIs; however, additional reductions in inappropriate antibiotic prescribing are needed.

Antibiotic consumption at community pharmacies: A multicenter repeated prevalence surveillance using WHO methodology

Background:

Antibiotics are losing their effectiveness because of the rapid emergence of resistant bacteria. Unnecessary antimicrobial use increases antimicrobial resistance (AMR). There are currently no published data on antibiotic consumption in Pakistan at the community level. This is a concern given high levels of self-purchasing of antibiotics in Pakistan and variable knowledge regarding antibiotics and AMR among physicians and pharmacists.

Objective:

The objective of this repeated prevalence survey was to assess the pattern of antibiotic consumption data among different community pharmacies to provide a baseline for developing future pertinent initiatives.

Methods:

A multicenter repeated prevalence survey conducted among community pharmacies in Lahore, a metropolitan city with a population of approximately 10 million people, from October to December 2017 using the World Health Organization (WHO) methodology for a global program on surveillance of antimicrobial consumption.

Results:

The total number of defined daily doses (DDDs) dispensed per patient ranged from 0.1 to 50.0. In most cases, two DDDs per patient were dispensed from pharmacies. Co-amoxiclav was the most commonly dispensed antibiotic with a total number of DDDs at 1018.15. Co-amoxiclav was followed by ciprofloxacin with a total number of 486.6 DDDs and azithromycin with a total number of 472.66 DDDs. The least consumed antibiotics were cefadroxil, cefotaxime, amikacin, and ofloxacin, with overall consumption highest in December.

Conclusion:

The study indicated high antibiotic usage among community pharmacies in Lahore, Pakistan particularly broad-spectrum antibiotics, which were mostly dispensed inappropriately. The National action plan of Pakistan on AMR should be implemented by policymakers including restrictions on the dispensing of antimicrobials.

Evaluation of inappropriate antibiotic prescribing and management through pharmacist-led antimicrobial stewardship programmes: a meta-analysis of evidence

Purpose

This meta-analysis aims to evaluate inappropriate antibiotic prescribing in the Gulf region and determine the effect of pharmacist-led antimicrobial stewardship (AMS) programmes on reducing inappropriateness.

Method

Articles were searched, analysed, and quality assessed through the risk of bias (ROB) quality assessment tool to select articles with a low level of bias. In step 1, 515 articles were searched, in step 2, 2360 articles were searched, and ultimately 32 articles were included by critical analysis. Statistical analysis used to determine risk ratio and standard mean differences were calculated using Review manager 5.4; 95% confidence intervals were calculated using the fixed-effect model. The I² statistic assessed heterogeneity. In statistical heterogeneity, subgroup and sensitivity analyses, a random effect model was performed. The α threshold was 0.05. The primary outcome was inappropriateness in antibiotic prescribing in the Gulf region and reduction of inappropriateness through AMS.

Result

Detailed review and analysis of 18 studies of inappropriate antibiotic prescribing in the Gulf region showed the risk of inappropriateness was 43 669/100 846=43.3% (pooled RR 1.31, 95% CI 1.30 to 1.32). Test with overall effect was 58.87; in the second step 28 AMS programmes led by pharmacists showed reduced inappropriateness in AMS with pharmacist versus pre-AMS without pharmacist (RR 0.36, 95% CI 0.32 to 0.39).

Conclusion

Inappropriate antibiotic prescribing in the Gulf region is alarming and needs to be addressed through pharmacist-led AMS programmes.

Exploring Undergraduate Pharmacy Students Perspectives Towards Antibiotics Use, Antibiotic Resistance, and Antibiotic Stewardship Programs Along With the Pharmacy Teachers' Perspectives: A Mixed-Methods Study From Pakistan

Background: Antibiotic resistance (ABR) is one of the major issues around the globe. Timely education and awareness of pharmacy students regarding the appropriate use of antibiotics, ABR, and antimicrobial stewardships are required.

Methods: The present study was first conducted in 12 (public and private sector) universities among undergraduate pharmacy students (UGPS) (n = 414) irrespective of their study year through a validated questionnaire, and the insights of pharmacy teachers were taken through in-depth semi-structured interviews in the second phase. For the quantitative data, different statistical methods were used, and data were presented in tabulated form, whereas inductive thematic interpretation was used to categorize themes and derive conclusions from qualitative evidence.

Results: The majority of the students were males (n = 223, 54%) with the mean age group 19–23 years, and 20 faculty members were interviewed with a mean duration of 15 min. Students have good knowledge about antibiotics use and the majority purchased antibiotics through prescription (n = 277, 66.9%) during the last month and strongly agreed to stop unnecessary household storage (n = 183 44.2%). Most of the students have heard the terminologies related to antimicrobial resistance through social media while unaware (n = 104, 25.1%) of a Pakistan national action plan against AMR (antimicrobial resistance). Overall, respondents have a somewhat good understanding of the ABR. Regular use of antibiotics without consultation of a physician can lead to ABR and some wrong answers were observed (162, 39.1%; p > 0.05). The majority of the students (n = 198, 47.8%) and teachers believe that the current pharmacy syllabus must be swiftly updated with the new subjects related to ABR and AMS (antimicrobial stewardship) in Pakistan. The UGPS have emphasized (n = 220, 53.1%; Median = 1, IQR = 2) establishing a link between academia and hospitals. The ABR issue has been highlighted by pharmacy faculty members, who have urged students to take practical efforts toward ABR and AMS knowledge.

Conclusion: The UGPS knowledge related to ABR and AMS must be updated. Students at the undergraduate level must get training in order to encourage the sensible use of antibiotics. Courses on ABR and AMS should be included in present pharmacy curricula.

Impact of pharmacist intervention in antibiotic stewardship programmes for critically ill neonates: A systematic review and meta-analysis

WHAT IS KNOWN AND OBJECTIVE

Antibiotic stewardship programmes (ASPs) are introduced to ensure effective antibiotic use. Pharmacists can be involved in ASPs to facilitate the appropriate antibiotic use. Prolonged use of antibiotics causes adverse events in critically ill neonates. Hence, this systematic review and meta-analysis was aimed at investigating pharmacists' functions in ASPs in critically ill neonates and the effect of ASP implementation on antibiotic use.

METHODS

A comprehensive search of PubMed/Medline, Embase, and Cochrane Library databases until January 2021 was conducted and studies that reported the functions of pharmacists in ASPs for critically ill neonates and the results of ASP implementation were included in this review. All processes were performed by two reviewers independently, and any discordance between the two was resolved by discussion.

RESULTS AND DISCUSSION

In all, 19 studies were included in this review. Pharmacists were found to have various functions in ASPs, such as participating in the development of antibiotic use guidelines, auditing antibiotic prescriptions, participating in multidisciplinary ward rounds, educating other ASP team members, checking blood culture or laboratory data, and monitoring antibiotic use. A meta-analysis revealed that ASP implementation in critically ill neonates was significantly associated with a 23% reduction in the overall antibiotic use rate (ratio of means: 0.77, 95% confidence interval: 0.69-0.87, p < 0.001). Moreover, the overall duration of antibiotic therapy significantly reduced by 15% with ASP implementation (ratio of means: 0.85, 95% confidence interval: 0.78-0.91, p < 0.001).

WHAT IS NEW AND CONCLUSION

The implementation of ASPs involving pharmacists, especially in critically ill neonates, was associated with the reduced use and duration of antibiotic treatment. Thus, pharmacists played a key role in ASPs in critically ill neonates.

The effectiveness of Check of Medication Appropriateness for antimicrobial stewardship: an interrupted time series analysis

OBJECTIVES

Inappropriate prescribing of antimicrobials in hospitals contributes to the emergence of resistance and adverse drug events. To support antimicrobial stewardship (AMS), clinical decision rules focusing on antimicrobial therapy were implemented in the 'Check of Medication Appropriateness' (CMA). The CMA is a hospital-wide pharmacist-led medication review service consisting of a clinical rule-based screening for potentially inappropriate prescriptions (PIPs). We aimed to investigate the impact of the CMA on antimicrobial prescribing.

METHODS

An interrupted time series study was performed at the University Hospitals Leuven. The pre-implementation cohort was exposed to standard-of-care AMS. Afterwards, an AMS-focused CMA comprising 41 specific clinical rules, targeting six AMS objectives, was implemented in the post-implementation period. A regression model was used to assess the impact of the intervention on the number of AMS-related residual PIPs between both periods. The total number of recommendations and acceptance rate was recorded for the 2 year post-implementation period.

RESULTS

Pre-implementation, a median proportion of 75% (range: 33%-100%) residual PIPs per day was observed. After the CMA intervention, the proportion was reduced to 8% (range: 0%-33%) per day. Use of clinical rules resulted in an immediate relative reduction of 86.70% (P < 0.0001) in AMS-related residual PIPs. No significant underlying time trends were observed during the study period. Post-implementation, 2790 recommendations were provided of which 81.32% were accepted.

CONCLUSIONS

We proved that the CMA approach reduced the number of AMS-related residual PIPs in a highly significant and sustained manner, with the potential to further expand the service to other AMS objectives.

Novel Multidisciplinary Approach for Outpatient Antimicrobial Stewardship Using an Emergency Department Follow-Up Program

Purpose: Outpatient antimicrobial stewardship programs (ASPs) are becoming increasingly prevalent in healthcare. Many programs have demonstrated the effectiveness of pharmacist-driven outpatient consultations or follow-up programs to ensure appropriate antimicrobial prescribing. However, there is a paucity of literature describing multidisciplinary approaches in large healthcare systems for patients discharged from the emergency department (ED). The objective of this study was to describe the feasibility and impact of a combined effort between ASP pharmacotherapy specialists and nurse practitioners (NPs) in managing an ED follow-up center. Methods: A retrospective analysis was conducted for patients discharged from the ED between January 2018 and June 2019. Patients were identified for inclusion based on documentation by ASP pharmacotherapy specialists in the electronic health record for patient-specific inquiries from ED follow-up center NPs. The primary outcome of this study was to describe the number and types of interventions made by ASP pharmacotherapy specialists. Results: A total of 1088 patients were included in the study, for 1114 documented ASP calls. The urinary tract was the most common source of positive culture (79%), and third-generation cephalosporins were the most frequent antibiotic associated with calls (20%). Out of total calls, 60% lead to ASP interventions. Among total calls, the most frequent interventions were to correct drug-bug mismatches (20%), initiate new therapy (10%), and discontinue therapy (7%). Conclusion: This report describes a novel initiative that combines the efforts of ED NPs and ASP pharmacotherapy specialists in managing an ED follow-up center at a large healthcare system.

Potential Impact of the Involvement of Clinical Pharmacists in Antimicrobial Stewardship Programs on the Incidence of Antimicrobial-Related Adverse Events in Hospitalized Patients: A Multicenter Retrospective Study

Although specialized pharmacists have been suggested to be essential members of antimicrobial stewardship programs (ASPs), not all hospitals in Korea operate ASPs with pharmacists involved. We aimed to evaluate the association of involvement of clinical pharmacists as team members of multidisciplinary ASPs with the incidence of antimicrobial-related adverse drug events (ADEs). Five tertiary teaching hospitals participated in this retrospective cohort study. At each participating hospital, we randomly selected 1000 participants among patients who had received systemic antimicrobial agents for more than one day during the first quarter of 2017. We investigated five categories of antimicrobial-related ADEs: allergic reactions, hematologic toxicity, nephrotoxicity, hepatotoxicity, and antimicrobial-related diarrhea. Multivariate logistic regression analysis was used to evaluate the potential impact of pharmacist involvement in ASPs on the incidence of ADEs. A total of 1195 antimicrobial-related ADEs occurred in 618 (12.4%) of the 4995 patients included in the analysis. The overall rate of ADE occurrence was 17.4 per 1000 patient days. Hospitals operating ASPs with pharmacists showed significantly lower AE incidence proportions than other hospitals (8.9% vs. 14.7%; p < 0.001). Multidisciplinary ASPs that included clinical pharmacists reduced the risk of antimicrobial-related ADEs by 38% (adjusted odds ratio 0.62; 95% confidence interval 0.50-0.77). Our results suggest that the active involvement of clinical pharmacists in multidisciplinary ASPs may contribute to reduce the incidence of antimicrobial-related ADEs in hospitalized patients.

Impact of pharmacist-led selective audit and feedback on outpatient antibiotic prescribing for UTIs and SSTIs

PURPOSE

An estimated 30% of all outpatient antibiotic prescriptions in the United States are unnecessary. The Joint Commission, in 2016, implemented core elements of performance requiring antimicrobial stewardship programs (ASPs) to expand to outpatient practice settings. A study was conducted to determine whether pharmacist-led audit and feedback would improve antibiotic prescribing for urinary tract infections (UTIs) and skin and soft tissue infection (SSTIs) at 2 primary care practices.

METHODS

A retrospective, quasi-experimental study was conducted to evaluate antibiotic prescribing for patients treated for a UTI or SSTI at 2 primary care offices (a family medicine office and an internal medicine office). The primary objective was to compare the rate of appropriate antibiotic prescribing to patients treated before implementation of a pharmacist-led audit-and-feedback process for reviewing antibiotics prescribed for UTIs and SSTIs (the pre-ASP group) and patients treated after process implementation (the post-ASP group). Total regimen appropriateness was defined by appropriate antibiotic selection, dose, duration, and therapy indication in accordance with institutional outpatient empiric therapy guidelines. Secondary objectives included comparing rates of infection-related revisits and Clostridioides difficile infection between groups.

RESULTS

A total of 400 patients were included in the study (pre-ASP group, n = 200; post-ASP group, n = 200). The rate of total antibiotic prescribing appropriateness improved significantly, from 27.5% to 50.5% (P < 0.0001), after implementation of the audit-and-feedback process. There were also significant improvements in the post-ASP group vs the pre-ASP period in the individual components of regimen appropriateness: appropriate drug (70% vs 53%, P < 0.001), appropriate duration (83.5% vs 57.5%, P < 0.001), and appropriate therapy indication (98% vs 94%, P = 0.041). There were no significant between-group differences in other outcomes such as rates of adverse events, treatment failure, C. difficile infection, and infection-related revisits or hospitalizations within 30 days.

CONCLUSION

A pharmacist-led audit-and-feedback outpatient stewardship strategy was demonstrated to achieve significant improvement in outpatient antibiotic prescribing for UTI and SSTI.

Clinical impact of pharmacist-led antibiotic stewardship programs in outpatient settings in the United States: A scoping review

Disclaimer

In an effort to expedite the publication of articles related to the COVID-19 pandemic, AJHP is posting these manuscripts online as soon as possible after acceptance. Accepted manuscripts have been peer-reviewed and copyedited, but are posted online before technical formatting and author proofing. These manuscripts are not the final version of record and will be replaced with the final article (formatted per AJHP style and proofed by the authors) at a later time.

Purpose

To provide an overview of the impact of pharmacist interventions on antibiotic prescribing and the resultant clinical outcomes in an outpatient antibiotic stewardship program (ASP) in the United States.

Methods

Reports on studies of pharmacist-led ASP interventions implemented in US outpatient settings published from January 2000 to November 2020 and indexed in PubMed or Google Scholar were included. Additionally, studies documented at the ClinicalTrials.gov website were evaluated. Study selection was based on predetermined inclusion criteria; only randomized controlled trials, observational studies, nonrandomized controlled trials, and case-control studies conducted in outpatient settings in the United States were included. The primary outcome was the observed differences in antibiotic prescribing or clinical benefits between pharmacist-led ASP interventions and usual care.

Results

Of the 196 studies retrieved for full-text review, a cumulative total of 15 studies were included for final evaluation. Upon analysis, we observed that there was no consistent methodology in the implementation of ASPs and, in most cases, the outcome of interest varied. Nonetheless, there was a trend toward improvement in antibiotic prescribing with pharmacist interventions in ASPs compared with that under usual care (P < 0.05). However, the results of these studies are not easily generalizable.

Conclusion

Our findings suggest a need for a consistent approach for the practical application of outpatient pharmacist-led ASPs. Managed care organizations could play a significant role in ensuring the successful implementation of pharmacist-led ASPs in outpatient settings.

PHarmacist Avoidance or Reductions in Medical Costs in Patients Presenting the EMergency Department: PHARM-EM Study

To comprehensively classify interventions performed by emergency medicine clinical pharmacists and quantify cost avoidance generated through their accepted interventions.

DESIGN

A multicenter, prospective, observational study was performed between August 2018 and January 2019.

SETTING

Community and academic hospitals in the United States.

PARTICIPANTS

Emergency medicine clinical pharmacists.

INTERVENTIONS

Recommendations classified into one of 38 intervention categories associated with cost avoidance.

MEASUREMENTS AND MAIN RESULTS

Eighty-eight emergency medicine pharmacists at 49 centers performed 13,984 interventions during 917 shifts that were accepted on 8,602 patients and generated $7,531,862 of cost avoidance. The quantity of accepted interventions and cost avoidance generated in six established categories were as follows: adverse drug event prevention (1,631 interventions; $2,225,049 cost avoidance), resource utilization (628; $310,582), individualization of patient care (6,122; $1,787,170), prophylaxis (24; $22,804), hands-on care (3,533; $2,836,811), and administrative/supportive tasks (2,046; $342,881). Mean cost avoidance was $538.61 per intervention, $875.60 per patient, and $8,213.59 per emergency medicine pharmacist shift. The annualized cost avoidance from an emergency medicine pharmacist was $1,971,262. The monetary cost avoidance to pharmacist salary ratio was between $1.4:1 and $10.6:1.

CONCLUSIONS

Pharmacist involvement in the care of patients presenting to the emergency department results in significant avoidance of healthcare costs, particularly in the areas of hands-on care and adverse drug event prevention. The potential monetary benefit-to-cost ratio for emergency medicine pharmacists is between $1.4:1 and $10.6:1.

Understanding of Pharmacy Students towards Antibiotic Use, Antibiotic Resistance and Antibiotic Stewardship Programs: A Cross-Sectional Study from Punjab, Pakistan

Antibiotic resistance (ABR) is a significant issue for public health globally. An adequate understanding of ABR and the approaches used to tackle ABR, including antibiotic stewardship programs, are vital. This study aimed to get an insight into antibiotic use, ABR, and antibiotic stewardship programs among pharmacy students of Punjab, Pakistan. This multicenter study was undertaken among final (fifth) year undergraduate pharmacy students of 7 universities of Punjab, Pakistan. A paper-based self-administered questionnaire comprising 48-items was utilized for data collection. Descriptive and inferential statistics were employed for data analysis. This study included a total of 296 respondents with a response rate of 85.8%. Most of the students had an average understanding of antibiotic use (59.8%), ABR (42.6%), ABR mechanisms (48.0%), and factors of ABR (51.7%). Only 21.6% of students have heard about antibiotic stewardship programs. More than half of the students believed that educating and training healthcare professionals (53.4%) and medical students (57.8%) about the prescribing and judicial usage of antibiotics could reduce the ABR burden. The awareness of most of the pharmacy students about certain aspects of antibiotic use, ABR, and stewardship programs was suboptimal.

Practice-enhancing publications about the medication-use process in 2019

PURPOSE

This article identifies, prioritizes, and summarizes published literature on the medication-use process (MUP) from calendar year 2019 that can impact health-system pharmacy daily practice. The MUP is the foundational system that provides the framework for safe medication utilization within the healthcare environment. The MUP is defined in this article as having the following components: prescribing/transcribing, dispensing, administration, and monitoring. Articles that evaluated one of the steps were gauged for their usefulness in promoting daily practice change.

SUMMARY

A PubMed search was conducted in January 2020 for calendar year 2019 using targeted Medical Subject Headings keywords; in addition, searches of the table of contents of selected pharmacy journals were conducted. A total of 4,317 articles were identified. A thorough review identified 66 potentially practice-enhancing articles: 17 for prescribing/transcribing, 17 for dispensing, 7 for administration, and 25 for monitoring. Ranking of the articles for importance by peers led to the selection of key articles from each category. The highest-ranked articles are briefly summarized, with a mention of why each article is important within health-system pharmacy. The other articles are listed for further review and evaluation.

CONCLUSION

It is important to routinely review the published literature and to incorporate significant findings into daily practice; this article assists in identifying and summarizing the most impactful recently published literature in this area. Health-system pharmacists have an active role in improving the MUP in their institution, and awareness of the significant published studies can assist in changing practice at the institutional level.

Decreased Overall and Inappropriate Antibiotic Prescribing in a Veterans Affairs Hospital Emergency Department following a Peer Comparison-Based Stewardship Intervention

Antibiotic prescribing is very common in emergency departments (EDs). Optimal stewardship intervention strategies in EDs are not well defined. We conducted a prospective, observational cohort study in a Veterans Affairs ED in which clinician education and monthly e-mail-based peer comparisons were directed against all oral antibiotic prescribing for discharged patients. Oral antibiotic prescriptions were compared in baseline (June 2016 to December 2017) and intervention (January to June 2018) periods using an interrupted time series regression model. Prescribing appropriateness was compared during January to June 2017 and the intervention period. During the intervention period, antibiotic prescriptions decreased monthly by 10.4 prescriptions per 1,000 ED visits (P = 0.07 [95% confidence interval {CI}, -21.7 to 1.0]). The relative decrease in the trend of antibiotic prescriptions during the intervention period compared to baseline was 9.9 prescriptions per 1,000 ED visits per month (P = 0.07 [95% CI, -20.9 to 1.0]). The intervention was associated with a significant decrease and increase in amoxicillin-clavulanate and cephalexin prescriptions, respectively (P < 0.001, P = 0.004). Decreasing trends in ciprofloxacin prescriptions during the baseline period were maintained during the intervention. Unnecessary antibiotic prescribing (i.e., antibiotic not indicated) decreased from 55.6% to 38.7% during the intervention (30.4% decrease, P = 0.003). Optimal antibiotic prescribing (i.e., antibiotics were indicated, and a guideline-concordant agent was prescribed for guideline-concordant duration) increased by 36% (21.6% to 29.3%, P = 0.12). A peer comparison-based stewardship intervention directed at ED clinicians was associated with reductions in overall and unnecessary oral antibiotic prescribing. There is potential to further improve antibiotic use as suboptimal prescribing remained common.

Collaborative Antimicrobial Stewardship in the Emergency Department

Given the large number of patients seen in the emergency department (ED) and concerns with antibiotic overprescribing, the ED is an important setting to target for antimicrobial stewardship (AS) initiatives. The ED is positioned between ambulatory and inpatient settings, making AS collaboration with clinicians and other health care providers in the hospital, long-term care facilities, and ambulatory settings critical to success. This article details ED-focused AS strategies on empiric antimicrobial selection, prompt administration, preventing ED return and readmissions, suggested collaborations between ED AS leadership and other key partners, and potential future strategies for expansion.

Antibiotic prescribing patterns for adult urinary tract infections within emergency department and urgent care settings

Urinary tract infections (UTI) are a common reason for emergency department (ED) and urgent care (UC) visits. Fluoroquinolones (FQ) are frequently prescribed for treatment of UTI in the outpatient setting; however, data evaluating prescribing patterns after FDA safety warnings is limited, especially in UC. The study goal was to investigate and compare antimicrobial prescribing for UTIs in a single-site ED and an off-site UC in an urban, academic health system. This retrospective study included patients presenting with a UTI to the ED or UC between January and June 2018. Those 18 years or older with uncomplicated, complicated UTI, or pyelonephritis were included. Exclusion criteria were catheter-related UTI, urinary tract abnormalities, immunocompromised, or hospitalization. Primary outcome was FQ prescribing rate for all UTI in the ED and UC. Secondary outcomes were rates of non-FQ prescribing, re-presentation, bug-drug mismatch, and treatment durations. 184 patients were included. FQ prescribing rate was similar in ED and UC (21.2% vs. 16.3%, p = 0.4). Non-FQs prescribed in ED and UC were nitrofurantoin (20.2% vs 53.6%), beta-lactams (46.1% vs 22.6%), and trimethoprim/sulfamethoxazole (12.5% vs. 5%). A longer than recommended duration was identified in 46.3% UC patients compared to 21.2% ED patients. Thirty-day re-presentation with persistent UTI symptoms occurred more frequently in the ED compared to UC (13.5% vs. 7.5%). Predictors of FQ prescribing on logistic regression were male, recurrent UTI, and malignancy. FQ prescribing rate for UTI treatment was low with no difference between ED and UC. Opportunity exists to improve treatment duration and antimicrobial choice.

The Effectiveness of Clinical Pharmacist-Led Consultation in the Treatment of Infectious Diseases: A Prospective, Multicenter, Cohort Study

Background

Antimicrobial resistance (AMR) is a serious global health threat and leads to a huge challenge to infectious diseases (ID) treatment. To tackle AMR, regional ‘Antimicrobial Stewardship Programs’ (ASP) have been implemented in many countries. Due to insufficient clinical pharmacy resources, a major intervention mode of ASP in China is through clinical pharmacist-led consultation (CPC). The current study aims to prospectively evaluate this intervention and compare the effectiveness of CPC served by ID and non-ID clinical pharmacists.

Methods

We conducted a prospective and multicenter cohort study based on a regional registry database in 17 hospitals in Western China, including consecutive patients with ID between April 2017 and December 2019. Baseline characteristics including sex, age, liver and kidney function, comorbidity, infection severity were prospectively collected and recorded. The main exposure of interest was whether the attending physician adopted recommendations of the clinical pharmacist in the therapeutic scheme. The outcome was the infection effective response, assessed during day 3–7 after completing CPC. Multivariate analyses were performed by generalized linear mixed models.

Results

A total of 2,663 ID patients were included in the final analysis according to the predesigned inclusion and exclusion criteria. The number of patients whose treatment followed and did not follow the pharmacists’ suggestion was 2,529 and 134, respectively. CPC intervention could improve the ID patient prognosis in the context of other confounders controlled (Adjusted Odds ratio(AOR)=1.838, 95%Confidence Interval(CI)=[1.212, 2.786]), and the effectiveness of CPC served by ID and non-ID clinical pharmacists might be equivalent (AOR=0.958, 95%CI[0.740, 1.240]). Special consultation (AOR=1.832, 95%CI[1.106, 3.035]) and surgical treatment of infectious sites (AOR=1.380, 95%CI[1.039, 1.834]) had positive influences on the patient prognosis, while hypoalbuminemia (AOR=0.694, 95%CI[0.523, 0.921]), liver dysfunction (AOR=0.705, 95%CI[0.559, 0.889]), presence of high-risk factors (AOR=0.775, 95%CI[0.613, 0.980]), and increased infection severity (AOR=0.631, 95%CI[0.529, 0.753])were associated with a decrease in effective response rate, independently.

Conclusion

This study suggests that CPC is a promising pharmacist-led intervention to improve ID treatment, and it can achieve standardization among clinical pharmacists with different backgrounds by some measures. Policy/decision-makers should promote this intervention mode in developing countries or regions where there is an insufficient number of clinical pharmacists.

Pharmacist-supported antimicrobial stewardship in a retirement home

In an 80-bed fee-based retirement home with nursing care, the dispatched-pharmacist has provided prescription recommendations to visiting physicians based on pathogen identification using Gram staining as part of an antimicrobial stewardship program. Thus, we evaluated the effects of pharmacist-supported antimicrobial stewardship. We calculated the total number of all antimicrobials and macrolides, fluoroquinolones, and cephalosporins prescriptions per 100 residents per month at the retirement home from January 2013 to December 2017. Using log-transformed monthly resident numbers with an offset before and after the intervention, we performed Poisson regression analyses that adjusted for monthly mean age. Interrupted time series analyses (ITSA) were conducted to examine the changes in the incidence rate ratios for the baseline and slope before and after the intervention. The total number of all antimicrobial prescriptions per 100 residents per month from 2013 to 2017 was 14.10, 18.51, 10.59, 5.41, and 3.90, respectively. Although there was a significant pre-intervention increase in the total number of all antimicrobial prescriptions, the intervention was followed by a significant decrease. There was also a significant reduction in the slope. ITSA of the changes in the prescription of macrolides and fluoroquinolones showed that there were significant pre-intervention increase and followed by a significant post-intervention decrease in the slope. There was no significant change in cephalosporin prescriptions by the intervention. Our study shows that pharmacist-supported AS can reduce antimicrobial prescriptions in a retirement home. Nevertheless, further studies are needed to collect and analyse more data on similar interventions.

Pharmacist-Driven Culture and Sexually Transmitted Infection Testing Follow-Up Program in the Emergency Department

Expanding pharmacist-driven antimicrobial stewardship efforts in the emergency department (ED) can improve antibiotic management for both admitted and discharged patients. We piloted a pharmacist-driven culture and rapid diagnostic technology (RDT) follow-up program in patients discharged from the ED. This was a single-center, pre- and post-implementation, cohort study examining the impact of a pharmacist-driven culture/RDT follow-up program in the ED. Adult patients discharged from the ED with subsequent positive cultures and/or RDT during the pre- (21 August 2018–18 November 2018) and post-implementation (19 November 2018–15 February 2019) periods were screened for inclusion. The primary endpoints were time from ED discharge to culture/RDT review and completion of follow-up. Secondary endpoints included antimicrobial agent prescribed during outpatient follow-up, repeat ED encounters within 30 days, and hospital admissions within 30 days. Baseline characteristics were analyzed using descriptive statistics. Time-to-event data were analyzed using the Wilcoxon signed-rank test. One-hundred-and-twenty-seven patients were included, 64 in the pre-implementation group and 63 in the post-implementation group. There was a 36.3% reduction in the meantime to culture/RDT data review in the post-implementation group (75.2 h vs. 47.9 h, p < 0.001). There was a significant reduction in fluoroquinolone prescribing in the post-implementation group (18.1% vs. 5.4%, p = 0.036). The proportion of patients who had a repeat ED encounter or hospital admission within 30 days was not significantly different between the pre- and post-implementation groups (15.6 vs. 19.1%, p = 0.78 and 9.4% vs. 7.9%, p = 1.0, respectively). Introduction of a pharmacist culture and RDT follow-up program in the ED reduced time to data review, time to outpatient intervention and outpatient follow-up of fluoroquinolone prescribing.

Antibiotic Stewardship for Older Adults in Ambulatory Care Settings: Addressing an Unmet Challenge

Inappropriate antibiotic use is common in older adults (aged >65 y), and they are particularly vulnerable to serious antibiotic-associated adverse effects such as cardiac arrhythmias, delirium, aortic dissection, drug-drug interactions, and Clostridioides difficile. Antibiotic prescribing improvement efforts in older adults have been primarily focused on inpatient and long-term care settings. However, the ambulatory care setting is where the vast majority of antibiotic prescribing to older adults occurs. To help improve the clinical care of older adults, we review drivers of antibiotic prescribing in this population, explore systems aspects of ambulatory care that can create barriers to optimal antibiotic use, discuss existing stewardship interventions, and provide guidance on priority areas for future inquiry.

Factors that influence patient acceptance of clinical pharmacy services: A nationwide survey

OBJECTIVE

Examine the factors that influence a patient's likelihood of participating in clinical pharmacy services so that pharmacists can use this knowledge to effectively expand clinical services.

METHODS

An online survey was distributed to U.S. citizens 55 years of age or older through a market research company. The survey assessed pharmacy and medication use, general health, interest in clinical pharmacy services, and general demographics. The specific clinical services examined included medication therapy management (MTM) and a collaborative practice agreement (CPA). Logistic regression and best-worst scaling were used to predict the likelihood of participating and determine the motivating factors to participate in clinical pharmacy services, respectively.

RESULTS

Two hundred eight (58.45%) respondents reported being likely to participate in MTM services, and 108 (50.6%) reported being likely to participate in the services offered by a pharmacist with a CPA, if offered. The motivations to participate in MTM were driven by pharmacist management of medication interactions and adverse effects (best-worst scores 0.62 and 0.51, respectively). The primary motivator to participate in a CPA was improved physician-pharmacist coordination (best-worst score 0.80). Those with a personal pharmacist were more likely to participate in MTM (odds ratio [OR] 2.43 [95% CI 1.41-4.22], P = 0.002) and a pharmacist CPA (2.08 [1.26-3.44], P = 0.004). Previous experience with MTM increased the likelihood of participating again in MTM (5.98 [95% CI 2.50-14.35], P < 0.001). Patient satisfaction with the pharmacy increased the likelihood of participating in a pharmacist CPA (1.47 [95% CI 1.01-2.13], P = 0.04).

CONCLUSION

Patients are interested in clinical pharmacy services for the purposes of medication interaction management, adverse effect management, and improved physician-pharmacist coordination. The factors that influenced the likelihood of participating included having a personal pharmacist, previous experience with MTM, and pharmacy satisfaction. These results suggest a potential impact of the patient-pharmacist relationship on patient participation in clinical services.

Perspective of community pharmacists about community-based antimicrobial stewardship programs. A multicenter cross-sectional study from China

Background: Antimicrobial stewardship programs (ASPs) are commonly used worldwide to tackle antimicrobial resistance. The current study aimed to investigate the perspective of pharmacists on community-based ASPs in China.Methods: A multicenter cross-sectional study was conducted in the capital cities of three different provinces of China between March 2019 and July 2019. A systematic random sampling method was used to recruit respondents.Results: A response rate of 87.4% (416/476) was obtained. A large number of respondents (n = 308, 74.0%) believed that ASPs are vital to improving patient care (Median = 4, IQR = 2). Approximately one-third of the respondents (n = 142, 34.1%) always ask patients about their knowledge related to antimicrobials (Median = 4, IQR = 2). Additionally, a considerable number of respondents (n = 127, 30.5%) always, or often (n = 117, 28.1%) collaborated with other healthcare professionals (Median = 4, IQR = 2). Age, gender, and experience were observed to have a significant association (p < 0.05) with median scores of knowledge about antibiotics, perceptions, and practices on ASPs.Conclusions: The perceptions of pharmacists regarding ASPs were positive. However, gaps in knowledge about some aspects of antibiotics and participation in ASPs were found. The development of regional community-based ASPs is urgently required.

The Impact Of Pharmaceutical Interventions On The Use Of Carbapenems In A Chinese Hospital: A Pre-Post Study

Background

The challenge of drug resistance to carbapenems is of international concern with leading to increased hospital lengths of stay, costs, and mortality rates. How to get rid of the vicious cycle of drug resistance, new drugs, and re-resistance, and even the emergence of all-drug-resistant bacteria that humans cannot cope with, are the major challenges we face. To date, data about pharmaceutical interventions on the use of carbapenems are currently limited.

Patients and methods

A retrospective cohort study was conducted to compare pre- and post-intervention in Tongde Hospital of Zhejiang Province. Pharmaceutical interventions were performed in the post-intervention group, including real time monitoring of medication orders, educative group activities, and making interventions to physicians. Intervention acceptance and outcomes, including the length of hospital stay, readmission rates, 30-day mortality, and utilization of carbapenems, which was evaluated by the daily defined doses (DDDs), the days of therapy (DOTs), and the cost of carbapenems, were reviewed.

Results

During the study, 593 interventions were provided by clinical pharmacists with an average acceptance rate of 82.79%. Compared with the pre-intervention group, prescriptions of carbapenems for pathogen-directed therapy were improved significantly in the post-intervention group (59.27% vs 21.74%, p=0.022). The DDDs decreased from 281.96 to 174.28 and DOTs decreased from 9.19 to 5.18 after pharmaceutical intervention, and the pharmaceutical interventions had significantly lower mean total cost of carbapenems ($13,828.8 vs $8137.1, p=0.004) and length of hospital stay (9.3±1.5 vs 15.9±2.2, p=0.014). There was a significant reduction in 30-day mortality in the post-intervention group (9.46% vs 17.86%, p=0.013) while there were no differences found in the 30-day readmission (20.19% vs 20.66%, p=0.99).

Conclusion

Implementation of pharmaceutical interventions in our hospital successfully improved the appropriateness of carbapenem prescribing overall, and reduced the DDDs, DOTs, length of hospital day, and cost of carbapenems.
