A Qualitative Study of the Real-world Experiences of Infectious Diseases Fellows Regarding Antibiotic Stewardship

Skills, Not Just Knowledge: Infectious Diseases Fellows' Recommendations Regarding Antimicrobial Stewardship Training

BACKGROUND

Antimicrobial stewardship (AS) is an important topic in infectious diseases (ID) training, yet many ID fellowships lack formal training, and little is known about fellows' learning preferences.

METHODS

We conducted 24 in-depth interviews with ID fellows across the United States during 2018 and 2019 to explore their experiences with and preferences for AS education during fellowship. Interviews were transcribed, deidentified, and analyzed to identify themes.

RESULTS

Fellows had variable exposure to AS before and during fellowship, which impacted their knowledge about and attitude toward stewardship as a career; however, all fellows expressed the importance of learning general stewardship principles during fellowship. Some fellows' training included mandatory stewardship lectures and/or rotations, but most fellows felt their primary stewardship learning occurred through informal experiences in the clinical setting, such as holding the antimicrobial approval pager. Fellows expressed a preference for a standardized, structured curriculum that included in-person practical, interactive discussions with multidisciplinary faculty along with the opportunity to practice and apply their skills; however, they emphasized that time needed to be set aside for those educational activities. Although they wanted to learn the evidence and rationale for stewardship recommendations, they especially wanted training in and feedback on how to communicate stewardship recommendations to other health professionals, particularly in the setting of conflict.

CONCLUSIONS

ID fellows believe that standardized AS curricula should be included in their fellowship training, and they prefer structured, practical, and interactive learning experiences.

The protected antimicrobial process in a University Teaching Hospital: a qualitative interview study exploring the knowledge, attitudes, and experiences of healthcare professionals

Background The protected or restricted supply of certain antimicrobials such as linezolid, caspofungin, aztreonam, in the acute hospital setting is an important element of Antimicrobial Stewardship (AMS) programmes to address the growing problem of antimicrobial resistance. This process involves submitting an application for use to be reviewed typically by a Consultant Microbiologist, Infectious Disease Consultant or Antimicrobial Pharmacist. Aim To investigate healthcare professionals’ knowledge, experiences, and attitudes towards the protected/restricted antimicrobials process in order to identify possible methods of optimisation and improvement. Method Semi-structured interviews with stakeholders involved in the protected/restricted antimicrobial prescribing, dispensing and administration process were conducted in September–October 2019 in a 350-bed voluntary, general, acute hospital in Ireland. Interviews were analysed by the Framework method and mapped to the Theoretical Domains Framework (TDF). Results Interviews were conducted with 8 Doctors, 4 Pharmacists and 3 Nurses. TDF domains identified included: ‘Knowledge’; ‘Social/professional role and identity’; ‘Social influences’; ‘Memory, attention and decision processes’; ‘Beliefs about consequences’; ‘Environmental contexts and resources’. The relationship between prescribers and the AMS Team was reported as a facilitator of the process, whereas the inconsistency of the filing and versions of forms on the wards were seen as challenges. Conclusion The results of this study have shown that the existing protected/restricted antimicrobial process is a multi-disciplinary effort with barriers that require attention in order to make future improvements. Standardization of the form across all wards, an electronic version of the form, and structured education around AMS were suggested to optimize the process.

Understanding the complexities of antibiotic prescribing behaviour in acute hospitals: a systematic review and meta-ethnography

BACKGROUND

Antimicrobial resistance poses a serious global public health threat. Hospital misuse of antibiotics has contributed to this problem and evidence-based interventions are urgently needed to change inappropriate prescribing practices. This paper reports the first theoretical stage of a longer-term project to improve antibiotic prescribing in hospitals through design of an effective behaviour-change intervention.

METHODS

Qualitative synthesis using meta-ethnography of primary studies reporting doctors' views and experiences of antibiotic prescribing in hospitals for example, their barriers to appropriate prescribing. Twenty electronic databases were systematically searched over a 10-year period and potential studies screened against eligibility criteria. Included studies were quality-appraised. Original participant quotes and author interpretations were extracted and coded thematically into NVivo. All study processes were conducted by two reviewers working independently with findings discussed with the wider team and key stakeholders. Studies were related by findings into clusters and translated reciprocally and refutationally to develop a new line-of-argument synthesis and conceptual model. Findings are reported using eMERGe guidance.

RESULTS

Fifteen papers (13 studies) conducted between 2007 and 2017 reporting the experiences of 336 doctors of varying seniority working in acute hospitals across seven countries, were synthesised. Study findings related in four ways which collectively represented multiple challenges to appropriate antibiotic medical prescribing in hospitals: loss of ownership of prescribing decisions, tension between individual care and public health concerns, evidence-based practice versus bedside medicine, and diverse priorities between different clinical teams. The resulting new line-of-argument and conceptual model reflected how these challenges operated on both micro- and macro-level, highlighting key areas for improving current prescribing practice, such as creating feedback mechanisms, normalising input from other specialties and reducing variation in responsibility for antibiotic decisions.

CONCLUSIONS

This first meta-ethnography of doctors` experiences of antibiotic prescribing in acute hospital settings has enabled development of a novel conceptual model enhancing understanding of appropriate antibiotic prescribing. That is, hospital antibiotic prescribing is a complex, context-dependent and dynamic process, entailing the balancing of many tensions. To change practice, comprehensive efforts are needed to manage failures in communication and information provision, promote distribution of responsibility for antibiotic decisions, and reduce fear of consequences from not prescribing.

The state of antibiotic stewardship programs in 2021: The perspective of an experienced steward

Recognition of antibiotic stewardship programs (ASPs) as essential components of quality health care has dramatically increased in the past decade. The value of ASPs has been further reinforced during the coronavirus disease 2019 (COVID-19) pandemic because these programs were instrumental in monitoring antibiotic use, assessing emerging COVID-19 therapies, and coordinating implementation of monoclonal antibody infusions and vaccinations. ASPs are now required across hospital settings as a condition of participation for the Centers for Medicare and Medicaid Services and for accreditation by The Joint Commission. In the 2019 National Healthcare Safety Network annual survey, almost 89% of hospitals met the Seven Core Elements for ASPs defined by the Centers for Disease Control and Prevention. More than 61% of programs were co-led by physicians and pharmacists, evidence of the leadership role of both groups. ASPs employ many strategies to improve prescribing. Core interventions of preauthorization for targeted antibiotics, prospective audit and feedback, and development of local treatment guidelines have been supplemented with numerous emerging strategies. Diagnostic stewardship, optimizing duration of therapy, promoting appropriate conversion from intravenous to oral therapy, monitoring at transitions of care and hospital discharge, implementing stewardship initiatives in the outpatient setting, and increasing use of telemedicine are approaches being adopted across hospital settings. As a core function for medical facilities, ASP leaders must ensure that antibiotic use and ASP interventions promote optimal and equitable care. The urgency of success becomes progressively greater as complex patterns of antibiotic resistance continue to emerge, exacerbated by unpredictable factors such as a worldwide pandemic.

Perspectives of Physician and Pharmacist Stewards on Successful Antibiotic Stewardship Program Implementation: A Qualitative Study

Background

Antibiotic stewardship programs (ASPs) are required at every hospital regardless of size. We conducted a qualitative study across different hospital settings to examine perspectives of physician and pharmacist stewards about the dynamics within their team and contextual factors that facilitate the success of their programs.

Methods

Semistructured interviews were conducted in March-November 2018 with 46 ASP stewards, 30 pharmacists, and 16 physicians, from 39 hospitals within 2 large hospital systems.

Results

We identified 5 major themes: antibiotic stewards were enthusiastic about their role, committed to the goals of stewardship for their patients and as a public-health imperative, and energized by successful interventions; responsibilities of pharmacist and physician stewards are markedly different, and pharmacy stewards performed the majority of the day-to-day stewardship work; collaborative teamwork is important to improving care, the pharmacists and physicians supported each other, and pharmacists believed that having a strong physician leader was essential; provider engagement strategies are a critical component of stewardship, and recommendations must be communicated in a collegial manner that did not judge the provider competence, preferably through face-to-face interactions; and hospital leadership support for ASP goals and for protected time for ASP activities is critical for success.

Conclusions

The physician-pharmacist team is essential for ASPs; most have pharmacists leading and performing day-to-day activities with physician support. Collaborative, persuasive approaches for ASP interventions were the norm. Stewards were careful not to criticize or judge inappropriate antibiotic prescribing. Further research should examine whether this persuasive approach undercuts provider appreciation of stewardship as a public health mandate.

Learning Experiences Within Infectious Diseases Pharmacy Residency Programs in the United States: A Cross-Sectional Survey

Background

Pharmacists with residency training in infectious diseases (ID) optimize antimicrobial therapy outcomes in patients and support antimicrobial stewardship (AS) programs. Although most ID residencies are accredited and assessed by certain standards, the degree to which these programs are similar is not known.

Methods

A 19-item, cross-sectional, multicentered, electronic survey was distributed via e-mail to pharmacy residency program directors (RPDs) of all 101 second-year postgraduate (PGY-2) ID residency programs in the United States.

Results

Survey responses were collected from 71 RPDs (70.3%); 64.8% were associated with an academic medical center and 97.2% focused primarily in adult ID. Rotations in the microbiology laboratory, adult AS, and adult ID consult were required in 98.6% of residency programs. Only 28.2% of responding programs required pediatric AS and pediatric ID consult rotations. Programs at academic medical centers were more likely to offer immunocompromised host ID consult (P = .003), pediatric ID consult (P = .006), and hospital epidemiology (P = .047) rotations but less frequently offered outpatient AS (P = .003), viral hepatitis clinics (P = .001), and travel medicine clinics (P = .007) rotations compared to programs at nonacademic medical centers. Residents were frequently involved in AS committees (97.2%), pharmacokinetic dosing of antimicrobials (83.1%), precepting pharmacy trainees (80.3%), and performing research projects (91.5%).

Conclusions

The PGY-2 ID pharmacy residency programs demonstrated consistency in required adult ID consult, antimicrobial management activities, committee service, and teaching and research opportunities. Pediatric experiences were less common. The PGY-2 ID residency programs prepare pharmacists to become antimicrobial stewards for adult patients.
