Impact of an Infectious Disease Specialist on an Antimicrobial Stewardship Program at a Resource-Limited, Non-Academic Community Hospital in Korea.

ABSTRACT:

Background

Implementing a successful antimicrobial stewardship program (ASP) is difficult for non-academic community (NAC) hospitals due to insufficient infrastructure.

Aim

We evaluated the impact of an infectious disease specialist (IDS) on implementing an ASP in a resource-limited setting in Korea.

Methods

A retrospective study was performed at a NAC hospital between June 2015 and August 2018. An IDS has led an ASP at the hospital since June 2017. We used an interrupted time series analysis to evaluate longitudinal effects of the IDS-led ASP on the amount of antibiotic use and incidence of multidrug-resistant organism (MDRO) acquisition.

Findings

Total antibiotic use changed from 698.82 ± 74.41 to 602.09 ± 69.94 defined daily dose/1000 patient-days (PDs) after intervention. An immediate reduction in the use of carbapenems, glycopeptides, penicillins, and other antibiotics followed the IDS-led ASP. The 3rd/4th generation cephalosporins and carbapenems prescription rates decreased in slope after the intervention. Incidence of MDRO acquisition changed from 1.38, 0.78, and 0.21/1000 PDs to 1.06, 0.15, and 0.32/1000 PDs in methicillin-resistant Staphylococcus aureus, multidrug-resistant Acinetobacter baumannii, and multidrug-resistant Pseudomonas aeruginosa, respectively. The incidence of methicillin-resistant Staphylococcus aureus and multidrug-resistant Acinetobacter baumannii acquisition immediately decreased following intervention.

Conclusion

An IDS can implement a successful ASP by reducing antibiotic consumption and MDRO acquisition at resource-limited NAC hospitals.

Project description:Background:Infectious diseases consultant (IDC) pharmacists work within an IDC service to care for inpatients with complex infections. With Accreditation Canada's new Required Organizational Practice promoting the establishment of antimicrobial stewardship (AMS) programs, AMS pharmacists are being employed in acute care hospitals. There is potential for overlap in responsibilities between IDC and AMS pharmacists, but there is no literature outlining the current duties for each group in Canada. Objective:To describe the demographic characteristics and roles of IDC and AMS pharmacists in Canadian tertiary care academic hospitals. Methods:A survey of IDC and AMS pharmacists at Canadian tertiary care academic hospitals was conducted between February and April 2015. The questionnaire included questions about the pharmacist's experience, education, and training; the institution where the pharmacist was practising; the IDC or AMS team characteristics; and the pharmacist's roles in clinical, educational, administrative, and research sectors. Results:The survey response rate was 77% (68/88). The 68 respondents self-identified as IDC pharmacists (14 [21%]), AMS pharmacists (34 [50%]), or dual-role IDC and AMS pharmacists (20 [29%]). Compared with AMS pharmacists, IDC pharmacists reported more of the following unique clinical activities: directly communicating with patients, attending rounds, involving patients in decision-making, and providing patient education. The 3 groups of pharmacists described similar educational responsibilities. The AMS pharmacists performed more of the following administrative and research duties: development of antibiograms and preprinted orders, collection of antimicrobial metrics, and drug-use evaluations for antimicrobials. Dual-role IDC and AMS pharmacists were involved in fewer of the unique activities described by those who practised within a single subspecialty. Conclusions:Self-identified IDC and AMS pharmacists in Canadian tertiary care academic hospitals were performing many similar roles; however, distinct differences within the clinical, administrative, and research domains were identified among IDC pharmacists, AMS pharmacists, and those who identified as dual-role IDC and AMS pharmacists.

Project description:IntroductionDiabetic foot infections (DFIs) are the leading cause of non-traumatic lower extremity amputations in the United States. Antimicrobials active against methicillin-resistant Staphylococcus aureus (MRSA) are recommended in patients with associated risk factors; however, limited data exist to support these recommendations. Due to the changing epidemiology of MRSA, and the consequences of unnecessary antibiotic therapy, guidance regarding the necessity of empirical MRSA coverage in DFIs is needed. We sought to 1) describe the prevalence of MRSA DFIs at our institution and compare to the proportion of patients who receive MRSA antibiotic coverage and 2) identify risk factors for MRSA DFI.MethodsThis was a retrospective cohort study of all adult, culture-positive DFI patients managed at University Hospital, San Antonio, TX between January 1, 2010 and September 1, 2014. Patient eligibility included a principal ICD-9-CM discharge diagnosis code for foot infection and a secondary diagnosis of diabetes. The primary outcome was MRSA identified in the wound culture. Independent variables assessed included patient demographics, comorbidities, prior hospitalization, DFI therapies, prior antibiotics, prior MRSA infection, and laboratory values. Multivariable logistic regression was used to identify risk factors for MRSA DFI.ResultsOverall, 318 patients met inclusion criteria. Patients were predominantly Hispanic (79%) and male (69%). Common comorbidities included hypertension (76%), dyslipidemia (52%), and obesity (49%). S. aureus was present in 46% of culture-positive DFIs (MRSA, 15%). A total of 273 patients (86%) received MRSA antibiotic coverage, resulting in 71% unnecessary use. Male gender (OR 3.09, 95% CI 1.37-7.99) and bone involvement (OR 1.93, 1.00-3.78) were found to be independent risk factors for MRSA DFI.ConclusionsAlthough MRSA was the causative pathogen in a small number of DFI, antibiotic coverage targeted against MRSA was unnecessarily high.

Project description:In cancer patients, appropriate diagnosis and management of infection are frequently challenging owing to subtle or atypical presentation. We investigated the effectiveness of infectious disease (ID) consultations and the Antimicrobial Stewardship Program (ASP) in a Japanese cancer center. This 36-month-period, single-institution, interrupted time series analysis was retrospectively conducted during April 1, 2018-March 31, 2021, to evaluate a two-phase intervention: Phase 1 (notification of antimicrobials by the infection control team) and Phase 2 (establishing an ID consultation service and implementing ASP). Among 32,202 patients hospitalized, 22,096 and 10,106 hospitalizations occurred at baseline and during intervention period, respectively. The Antimicrobial Stewardship Team (AST) provided feedback on specific broad-spectrum antimicrobials in 913 instances (347 appropriate [38%]; 566 inappropriate [62%]), and 440 ID consultations were completed, with a 75% overall acceptance rate for AST suggestions. In Phase 2, monthly carbapenem days of therapy (CAR-DOT) decreased significantly, and narrow-spectrum antibiotic usage increased significantly in both trend and level; monthly DOT of antipseudomonal agents decreased significantly in trend. The results of these analyses of antimicrobial use are consistent with the DOT-based data based on antimicrobial use density (AUD). The total number of inpatient specimens increased significantly; the trend of multidrug-resistant Pseudomonas aeruginosa and methicillin-resistant Staphylococcus aureus infections decreased, without changes in the incidence of other resistant organisms, all-cause in-hospital mortality, and length of stay. Actual and adjusted CAR purchase costs per patient-day decreased without significant changes in the actual and adjusted purchase cost per patient-day for all intravenous antimicrobials. Combining ID consultation and ASP reduced carbapenem use without negative patient outcomes. Their implementation could facilitate establishment of safe cancer treatment facilities in Japan and improve prognosis in cancer patients.
