Influences on surgical antimicrobial prophylaxis decision making by surgical craft groups, anaesthetists, pharmacists and nurses in public and private hospitals

Results from a cluster-randomized, stepped-wedge trial testing a deliberative engagement intervention to increase guideline adherence among U.S. oral health providers

Dental sealants, an evidence-based clinical practice, can arrest occlusal non-cavitated carious lesions (NCCLs); however, U.S. oral health providers rarely provide this treatment. To increase providers' adoption of the practice, clinic leaders need to identify implementation strategies to deploy. Using a stepped wedge design across 16 cluster-randomized dental clinics, we examined whether small-group deliberative engagement enabled 680 oral health providers and staff to endorse implementation strategies and to increase placement of dental sealants on occlusal NCCLs. Participants deliberated about two barriers and eight implementation strategies. Sealant placement for occlusal NCCLs was extracted from the electronic health record. After deliberating, 49% of participants endorsed the first barrier and 37% endorsed the second barrier. Of those, 26% indicated a strategy was needed for the first barrier and 28% indicated a strategy was needed for the second. Consistent with this perceived lack of need for strategies, leaders did not deploy implementation strategies. Compared with the non-intervention period (98 clinic-months), in the intervention period (101 clinic-months), providers did not increase placement of sealants on occlusal NCCLs. Deliberative engagement may help clinic leaders efficiently evaluate support for implementation strategies, but future research is needed to determine how to increase guideline adoption.Trial Registration: This project is registered at ClinicalTrials.gov with ID NCT04682730.

Antimicrobial prophylaxis for endourological procedures in Jordanian hospitals: a multi-centre qualitative study

OBJECTIVES

To explore urologists' perceptions of barriers to, and facilitators of, adherence to international antimicrobial prophylaxis (AP) guidelines for endourological procedures in Jordan and to identify strategies to optimise guideline-concordant AP prescribing.

DESIGN

The present study is a qualitative study undertaken through semi-structured interviews and inductive thematic analysis. Study results are reported per Consolidated Criteria for Reporting Qualitative Research.

SETTING

Secondary and tertiary care across multiple public, private and academic hospitals in Jordan.

PARTICIPANTS

Nineteen practising urologists (all male; median age 32 years, IQR 8; nine residents, 10 specialists) who routinely prescribe AP for endourological procedures. Participants were recruited via convenience snowball sampling and interviewed until thematic saturation was reached.

INTERVENTIONS

Not applicable.

PRIMARY AND SECONDARY OUTCOME MEASURES

The main outcomes were themes describing perceived barriers to guideline adherence and potential facilitators to support appropriate AP use.

RESULTS

Participants identified several barriers: (1) patient level, strong expectations for antibiotics post-procedure and concerns about procedure-site hygiene; (2) clinician level, fear of postoperative infections and litigation, lack of familiarity with updated guidance and doubts about applying international guidelines locally; (3) system level, hierarchical prescribing dynamics, referral communication gaps, high workloads and time pressures, and concerns over sterilisation practices. Facilitators included targeted professional training and regular guideline updates for urologists, development of local AP guidelines informed by local resistance data, enhanced patient education campaigns and active involvement of clinical pharmacists in preoperative antibiotic review and auditing.

CONCLUSIONS

Urologists in Jordan face multifaceted barriers to AP guideline adherence. Future stewardship programmes can use insights from this study to develop locally tailored guidelines, targeted clinician training and pharmacist-led audits. Pilot testing with metrics such as prescribing rates, guideline concordance, antibiotic consumption and postoperative infection incidence will be essential to validate their impact before wider implementation.

Antibiotic prophylaxis for surgical-site infections and adherence to evidence-based guidelines

BACKGROUND

Antimicrobial prophylaxis is an established practice for reducing surgical-site infections; however, its misuse promotes alternative challenges including antimicrobial resistance. The objective of this study was to determine factors associated with adherence to surgical antibiotic prophylaxis guidelines.

METHODS

Adults aged 18 and older who underwent 1 of 5 selected procedures between 2004 and 2022 were included. The proportion of appropriate antibiotic prophylaxis was determined for each procedure type. A logistic regression model was built to identify factors impacting appropriate prophylaxis practices.

RESULTS

Among our cohort of 9,543 patients, 4,883 were women (51.2%); mean age was 60.1 years. Most patients were White (8,407; 88.1%). Cardiothoracic, neurosurgical, gastrointestinal, and plastic surgery procedures were individually associated with decreased odds of appropriate antibiotic prophylaxis use compared with orthopedic procedures (P < .05). Patients undergoing a cardiothoracic procedure were less likely to receive the correct antibiotic (59.0%). Patients undergoing a gastrointestinal procedure were less likely to receive prophylaxis with the appropriate start time (72.6%) or duration (5.4%). Appropriate antibiotic prophylaxis was more likely in patients who were male (odds ratio, 1.14; 95% confidence interval, 1.10-1.18) and White (odds ratio, 1.17; 95% confidence interval, 1.11-1.22). Appropriate prophylaxis was significantly greater in procedures after 2010 (representing the establishment of an antimicrobial stewardship program) compared with procedures before 2010 (odds ratio, 2.05; confidence interval, 1.95-2.16).

CONCLUSION

Appropriate antibiotic prophylaxis practices demonstrated significant variation according to specialty type, patient characteristics, and the implementation of an antimicrobial stewardship program. These findings suggest the beneficial role of stewardship programs and gaps where interventions can be targeted, particularly antibiotic selection and discontinuation timing.

Factors influencing physicians' antimicrobial prescribing decisions: A systematic review of qualitative studies

Inappropriate and overuse of antimicrobials is increasing antimicrobial resistance. Understanding physicians' antimicrobial decision-making is essential for developing interventions to optimize prescribing. The aim of this review was to identify the factors that influence physicians' antimicrobial prescribing decisions. A systematic literature search was conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Embase, Medline and Scopus were searched from 2014 onwards using three key concepts: antimicrobial, prescribing and attitude. The search identified 11 038 articles for review. Studies were included if they used qualitative methods and obtained data directly from physicians. Factors influencing antimicrobial prescribing were extracted and categorized into physician-related, patient-related, medication- and condition-related, and external factors. A model of the antimicrobial prescribing process was created to illustrate how these factors influence decision-making. Fifty-three articles from 23 countries met the inclusion criteria. Forty factors influencing antimicrobial prescribing were identified, with the most common being time pressures, patient/carer demand for antimicrobials, diagnostic uncertainty, clinical experience, and the use of evidence-based guidelines and diagnostic tests. The harm to the patient and the physician of underprescribing were considered to outweigh the potential population harm of antimicrobial resistance due to overprescribing. Antimicrobial decision making is a complex process influenced by many different types of factors at each point in the prescribing journey. Awareness of these factors is vital for the success of interventions aiming to optimize antimicrobial prescribing. Future interventions should investigate how to balance individual and population harm whilst considering the individual factors that influence prescribing decisions.

A qualitative study on factors influencing health workers' uptake of a pilot surgical antibiotic prophylaxis stewardship programme in selected Georgian hospitals

Antimicrobial misuse in surgical antibiotic prophylaxis (SAP) can include the inappropriate use of broad-spectrum antibiotics or prolonged dosing. In 2021, a pilot antimicrobial stewardship programme (ASP) was launched in Georgia, which involved developing and adapting SAP guidelines, establishing an interprofessional SAP prescribing approach, collecting surgical site infection (SSI) data via routinely collected data and telephonic patient follow-ups, and providing surgical unit staff with prescribing feedback and training on antimicrobial resistance (AMR) and antimicrobial stewardship (AMS). ASP introduction was staggered across ten hospitals over three years. This study explored behavioural determinants of surgical teams' ASP uptake in five hospitals where the ASP was introduced or about to be introduced. Findings primarily concerned epidemiologists' and nurses' ASP-related behaviour. Those at ASP non-introduced hospitals were less involved in the SAP prescribing process, had lower AMR awareness, and lacked professional development opportunities. Those at ASP-introduced hospitals exhibited higher AMR knowledge and felt ASP participation boosted confidence, facilitated work, and furnished key professional development. Results indicate interprofessional collaboration on SAP prescribing supported ASP uptake across teams, and investment in health worker training and administrative encouragement ensured effective ASP participation and implementation. Findings highlight the crucial role of epidemiologists in SAP and illustrate a need for developing Georgian nurses' AMR competencies as a vehicle to address public AMR knowledge gaps. Longer-term ASP uptake will need to consider the regulatory context in which hospitals lack access to national-level SSI data and feedback on SSI reporting but are fined for reporting non-compliance. Despite resource limitations and a small sample size, the study engaged all pilot ASP health workers. Respondents' inexperience of qualitative research participation and ensuant hesitation limited exploration of motivational factors supporting health workers' ASP uptake, which could be explored in further research.

User perceptions of surgical antimicrobial prophylaxis guidelines in orthopaedic surgery in a tertiary Australian hospital

BACKGROUND

Surgical antimicrobial prophylaxis remains the most common indication for antimicrobial use in Australian hospitals. Despite efforts to improve practice, adherence to guideline recommendations continues to be suboptimal across surgical disciplines, including orthopaedics. The Therapeutic Guidelines: Antibiotic v16 currently advocates for single dose prophylaxis for open reduction internal fixation (ORIF) procedures. Audits undertaken in one Australian tertiary hospital have identified low levels of adherence to this recommendation. It is unclear as to why guidelines are not adhered to in this setting.

AIM

To understand the factors that influence multidose prescribing for ORIF procedures and the barriers and enablers to guideline use in an Australian tertiary hospital.

MATERIALS AND METHODS

Interviews (focus groups and one-on-one sessions) were held with orthopaedic surgeons (consultants), orthopaedic registrars, pharmacists, and anaesthetists from a tertiary public hospital in Australia. The Theoretical Domains Framework (TDF) was used to analyse results.

RESULTS

Six focus groups and three one-on-one interviews were conducted. Data were mapped to 12 TDF domains. Although clinicians were aware of guideline recommendations, this alone did not encourage the use of single dose prophylaxis. The decision to prescribe postoperative antibiotics was influenced by a combination of patient and environmental factors as well as fear of infection development. The lack of guideline specificity was commonly highlighted as a barrier to guideline use, as well as lack of agreement with guideline content. Enablers to guideline use included education that was targeted and repetitive, as well as improved dissemination of guidelines.

CONCLUSION

There are myriad factors that influence the decision to prescribe postoperative antibiotics for ORIF procedures. By understanding the social and cultural context of a local setting and the barriers and enablers that pertain to an environment, interventions can be developed to enhance guideline use, thereby improving antimicrobial prescribing.

Individual and System-level Factors Contributing to Guideline Nonadherent Surgical Antibiotic Prophylaxis at a Tertiary Healthcare System: A Qualitative Analysis

BACKGROUND

Antibiotics play a crucial role in preventing surgical site infections, yet adherence to Infectious Disease Society of America guidelines varies widely. This qualitative study aimed to explore factors influencing perioperative antibiotic administration and assess the potential impact of a clinical decision support tool on guideline adherence.

METHODS

In this qualitative study, perioperative personnel with diverse roles (surgeons, anesthesiologists, certified nurse anesthetists, trainees, and pharmacists) were interviewed using a semistructured interview format from September 2023 through April 2024. Interviews were then analyzed for codes, which were assigned to concepts using the constant comparison method for assessment of factors that were described as barriers or facilitators of guideline adherence.

RESULTS

After 3 piloting interviews, 9 sessions were conducted with a total of 17 participants: 7 attending anesthesiologists, 3 resident trainees, 2 perioperative pharmacists, 3 Certified Registered Nurse Anesthetists, and 2 attending surgeons. Key themes emerged: (1) limited familiarity with Infectious Disease Society of America antibiotic guidelines, (2) lack of standardization and optimization of antibiotic decision-making process, (3) challenges with managing β-lactam allergies, (4) difficulty optimizing vancomycin timing, and (5) perceived benefit of a clinical decision support tool in enhancing workflow and guideline adherence.

CONCLUSIONS

Nonadherence to antibiotic guidelines in the perioperative setting often results from a lack of structured workflow. The interviews provide a foundation for developing a clinical decision support tool tailored to provider needs, aiming to improve user satisfaction and promote better adherence to perioperative antibiotic guidelines.

Clinicians' and Patients' Experiences and Perceptions on the Prevention and Management of Surgical Site Infections: A Mixed-Methods Systematic Review

AIM

To explore clinicians' and patients' perceptions of implementing evidence-based practice to improve clinical practice for preventing and managing surgical site infections within hospital acute care settings.

DESIGN

A convergent integrated mixed-methods systematic review using the Joanna Briggs Institute approach.

METHODS

Included studies reported (i) acute care hospital clinicians' and patients' experiences and preferences for preventing and managing surgical site infections and (ii) barriers and facilitators to implementing surgical site infection prevention and management guidelines. The Mixed Methods Appraisal Tool and the Quality Improvement Minimum Quality Criteria Set were used for critical appraisal. Quantitative data was transformed into qualitised data, then thematically synthesised with qualitative data and coded all findings into themes. Clinicians' and patients' views were also compared.

DATA SOURCES

English language peer-reviewed studies published from 2009 to March 2023 were identified from Medline, EMBASE, CINAHL, PsycINFO and Cochrane Central Library.

RESULTS

Thirty-seven studies (16 quantitative, 17 qualitative, 3 mixed-methods and 1 quality improvement) met the inclusion criteria. Five main themes represent key factors believed to influence the implementation of evidence-based surgical site infection prevention and management guidelines: (1) Intentional non-adherence to insufficiently detailed and outdated guidelines, (2) Knowledge deficits on evidence-based SSI care bring about inconsistent clinical practice, (3) Collaborative interdisciplinary and patient-provider relationship to enhance guideline uptake, (4) Infection surveillance to improve patient safety and quality of life and (5) Negative physical and psychological impacts on patients.

CONCLUSION

The five themes reflect a need for updated hospital guidelines as a medium to improve surgical site infection knowledge and ensure consistent and evidence-based clinical practice. This review also highlights the significance of interdisciplinary and patient-provider collaboration and infection surveillance to facilitate guideline uptake. The effectiveness of intervention bundles designed to improve these aspects of care will need to be evaluated in future research.

IMPACT

A future intervention bundle that includes (1) ensuring up-to-date hospital guidelines/policies; (2) fostering collaborative interdisciplinary teamwork culture between physicians, nurses, podiatrists, pharmacists and allied health professionals; (3) encouraging patient or carer involvement in shared decision-making and (4) implementing audit and feedback mechanism on infection surveillance is proposed to improve SSI prevention and management in acute care settings.

REPORTING METHOD

This paper followed the PRISMA 2020 checklist guideline for reporting systematic reviews.

PATIENT OR PUBLIC CONTRIBUTION

This mixed-methods systematic review collates evidence of clinicians' and patients' experiences and preferences for preventing and managing surgical site infections. The inclusion of hospital patients' perspectives supports the development of patient-centred interventions.

TRIAL REGISTRATION

The review protocol is registered on the International Prospective Register of Systematic Reviews (PROSPERO 2021 CRD42021250885). Available at: https://www.crd.york.ac.uk/prospero/display_record.php?ID=CRD42021250885.

Seeking simplicity, navigating complexity: How veterinarians select an antimicrobial drug, dose, and duration for companion animals

BACKGROUND

Minimizing harm from antimicrobials requires use of the narrowest spectrum drug, at an effective dose for the minimum effective duration. Many prescribers are not currently following these guidelines. To address suboptimal antimicrobial use, the underlying reasons must be understood.

OBJECTIVES

To identify factors influencing choices of antimicrobial drug, dose, and duration for companion animals.

SUBJECTS

Twenty-two veterinarians treating companion animals in Australia. Diversity of participants was deliberately sought.

METHODS

Semistructured interviews were conducted online. Two case studies were discussed, and then a range of broader questions was posed. Transcripts were analyzed thematically, using an inductive approach.

RESULTS

Few participants chose guideline-concordant management for the case studies. Prescribing choices were influenced by a complex array of factors associated with the clinical case, pet owner, drug, veterinarian, veterinary colleagues, and external factors. Key factors driving broad-spectrum antimicrobial use included a sense of safety, habit, ease of administering the drug (especially in cats), pharmaceutical marketing, and the self-perpetuating dispensary cycle. Many participants were concerned about antimicrobial resistance, but insufficiently informed about how to minimize this risk. Several participants believed that longer duration of treatment and ensuring patients finish a predetermined course would decrease the risk of antimicrobial resistance and improve clinical outcomes.

CONCLUSIONS AND CLINICAL IMPORTANCE

Veterinarians are engaged with the concept of antimicrobial stewardship, but face numerous practical barriers and require more information. In particular, improved education is needed on enhancing patient safety by minimizing both spectrum of activity and duration of treatment, and dispelling myths about "finishing the course."

Antimicrobial Stewardship in Healthcare: Exploring the Role of Nurses in Promoting Change, Identifying Barrier Elements and Facilitators-A Meta-Synthesis

BACKGROUND

Antimicrobial stewardship (AMS) involves a coordinated set of actions aimed at promoting the appropriate use of antibiotics within healthcare settings. This systematic review of qualitative studies assessed nurses' knowledge and perceptions of the barriers and facilitators that impact their involvement in AMS programs.

METHODS

This meta-synthesis followed the Joanna Briggs Institute methodology for systematic reviews of qualitative evidence. Relevant studies published between 2018 and 2023 were identified through searches on PubMed, CINAHL, EMBASE, PsycINFO, and Google Scholar. The studies were critically appraised using the CASP checklist, with 19 articles meeting the inclusion criteria from five continents.

RESULTS

Six recurring themes emerged from the analysis of nurses' experiences and opinions regarding their roles in AMS programs. These themes included the organization of AMS programs, availability of resources, training and education, communication, and the evolving role of nurses in AMS.

CONCLUSIONS

Nurses at every level of the profession might play a crucial role in antimicrobial stewardship. Although active involvement of nurses in antibiotic stewardship requires further exploration and research, this topic is being examined internationally. The literature on this subject primarily analyzes the phenomenon from a quantitative perspective rather than a qualitative one, and it is contextualized more within hospital settings rather than community settings.

Changes in parental anxiety and intention to demand antibiotics: A longitudinal study among parents during the COVID-19 pandemic

AIMS

Assessing the effects of the COVID-19 pandemic on parental anxiety and preferences for antibiotic treatment can help inform antibiotic stewardship strategies. Therefore, this study aimed to examine COVID-19 pandemic-related changes in parental anxiety levels, their intentions to demand antibiotics and frequencies of practising preventative behaviours.

DESIGN

This longitudinal quantitative study compared two groups of parents, those from Victoria and Western Australia, who experienced high and low COVID-19 risk, respectively.

METHODS

Participants were recruited through an online panel to complete three waves of surveys between October 2020 and August 2021. Anxiety scores and frequency of preventative behaviours were analysed using mixed-effects tobit regression, considering time, state, and their interaction as fixed effects predictors. Intention to demand antibiotics was modelled using multinomial logistic regression, with time, state, and their interaction as the predictors.

RESULTS

The final longitudinal sample comprised 50 participants from Victoria and 51 from Western Australia. Parental anxiety did not significantly change over time for either state. Intention to demand antibiotics was also stable over time within each state; however, participants from Victoria exhibited stronger intentions to demand antibiotics compared to those from Western Australia. Frequencies of parental preventative behaviours declined from Wave 1 to Wave 2 before increasing again in Wave 3, but only for Western Australia.

CONCLUSION

This longitudinal study among Australian parents found stable parental anxiety and intention to demand antibiotics within each state. However, the intention to demand antibiotics and preventative behaviours varied between states as per the COVID-19 risk. Thus, viral pandemics may not affect judicious antibiotic use, though the intention to demand antibiotics may increase in states with high COVID-19 risk.

IMPACT

Though parental anxiety may not impact antibiotic stewardship during viral respiratory illness outbreaks, tailored messaging to maintain appropriate antibiotic use may be necessary, especially when the disease risk is high.

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.

Antibiotic prophylaxis in trauma: Global Alliance for Infection in Surgery, Surgical Infection Society Europe, World Surgical Infection Society, American Association for the Surgery of Trauma, and World Society of Emergency Surgery guidelines

Trauma is a complex disease, and the use of antibiotic prophylaxis (AP) in trauma patients is common practice. However, considering the increasing rates of antibiotic resistance, AP use should be questioned and limited only to specific cases. Antibiotic stewardship is of paramount importance in fighting resistance spread. Definitive rules or precise indications about AP in trauma remain unclear. The present article describes the indications of AP in traumatic lesions to the head, brain, torso, maxillofacial, extremities, skin, and soft tissues endorsed by the Global Alliance for Infection in Surgery, Surgical Infection Society Europe, World Surgical Infection Society, American Association for the Surgery of Trauma, and World Society of Emergency Surgery.

Quality, availability and suitability of antimicrobial stewardship guidance: a multinational qualitative study

Background

Antimicrobial stewardship (AMS) programmes are established across the world to treat infections efficiently, prioritize patient safety, and reduce the emergence of antimicrobial resistance. One of the core elements of AMS programmes is guidance to support and direct physicians in making efficient, safe and optimal decisions when prescribing antibiotics. To optimize and tailor AMS, we need a better understanding of prescribing physicians' experience with AMS guidance.

Objectives

To explore the prescribing physicians' user experience, needs and targeted improvements of AMS guidance in hospital settings.

Methods

Semi-structured interviews were conducted with 36 prescribing physicians/AMS guidance users from hospital settings in Canada, Germany, Israel, Latvia, Norway and Sweden as a part of the international PILGRIM trial. A socioecological model was applied as an overarching conceptual framework for the study.

Results

Research participants were seeking more AMS guidance than is currently available to them. The most important aspects and targets for improvement of AMS guidance were: (i) quality of guidelines; (ii) availability of infectious diseases specialists; and (iii) suitability of AMS guidance to department context.

Conclusions

Achieving prudent antibiotic use not only depends on individual and collective levels of commitment to follow AMS guidance but also on the quality, availability and suitability of the guidance itself. More substantial commitment from stakeholders is needed to allocate the required resources for delivering high-quality, available and relevant AMS guidance to make sure that the prescribers' AMS needs are met.

Factors influencing pharmacists' clinical decision making in pharmacy practice

BACKGROUND

Pharmacists' clinical decision-making is considered a core process of pharmaceutical care in pharmacy practice, but little is known about the factors influencing this process.

OBJECTIVE

To identify factors influencing clinical decision-making among pharmacists working in pharmacy practice.

METHODS

Semi-structured interviews were conducted with pharmacists working in primary, secondary, and tertiary care settings in the Netherlands between August and December 2021. A thematic analysis was conducted using an inductive approach. The emerged themes were categorized into the Capability-Opportunity-Motivation-Behaviour (COM-B) model domains.

RESULTS

In total, 16 pharmacists working in primary care (n = 7), secondary care (n = 4) or tertiary care (n = 5) were interviewed. Factors influencing pharmacists' capability to make clinical decisions are a broad theoretical knowledge base, clinical experience, and skills, including contextualizing data, clinical reasoning, and clinical judgment. The pharmacy setting, data availability, rules and regulations, intra- and interprofessional collaboration, education, patient perspectives, and time are mentioned as factors influencing their opportunity. Factors influencing pharmacists' motivation are confidence, curiosity, critical thinking, and responsibility.

CONCLUSIONS

The reported factors covered all domains of the COM-B model, implying that clinical decision-making is influenced by a combination of pharmacists' capability, opportunity, and motivation. Addressing these different factors in pharmacy practice and education may improve pharmacists' clinical decision-making, thereby improving patient outcomes.

The impact of antimicrobial management by clinical pharmacists in obstetrics and gynecology on antimicrobial indicators, bacterial resistance and drug costs from 2011 to 2021 in China

Objectives

The goal of our study is to analyze the effectiveness and role of clinical pharmacists in antibiotic management through retrospective research from 2011 to 2021, depending on the current scenario of the antibiotic application in China.

Methods

We formed a team of pharmacists to carry out multifaceted intervention measures, such as forming a working group, developing a plan, establishing management rules via the pre-trial system, prescription comments, collaborating with the administrative department, implementing training and publicity, and so on. Antibiotic use was studied, bacterial drug resistance was determined, and antibiotic costs were computed.

Results

The pharmacist intervention and rectification of inappropriate antibacterial drug orders considerably enhanced the rational use rate of antibiotics and reduced the cost of antibiotics. Antibiotic use in clean surgery decreased from 90.22% to 11.14%, the use rate of antibiotics decreased from 63.82% to 30.26%, and antibiotic use intensity decreased from 42.75DDDs to 30.04DDDs. The types, timing, and course of antibacterials used in wards were all improved to varying degrees. Bacterial drug resistance improved noticeably, with resistance of Escherichia coli to cephalosporins, ciprofloxacin and carbapenems decreased in varying degrees. The use of antibacterial drugs has decreased significantly.

Conclusions

It is feasible and effective for pharmacists in gynecology and obstetrics to control antibiotic use, which plays a positive role in promoting the safe, effective, and cost-effective use of antibiotics and serves as a valuable reference for the antibiotic management.

Testing a Deliberative Democracy Engagement Intervention to Increase Guideline-Concordance Among Oral Health Providers: Results from the DISGO Cluster-Randomized, Stepped-Wedge Trial

Background

Dental caries affects billions worldwide and in the U.S. is among the most prevalent noncommunicable diseases in both children and adults. Early in the caries process, it can be arrested by dental sealants, which are non-invasive and thus tooth sparing, however, few dentists have adopted this approach. Deliberative engagement processes enable participants to engage with diverse perspectives on a policy issue and develop and share with policy makers informed opinions about the policy issue. We examined the effects of a deliberative engagement process on the ability of oral health providers to endorse implementation interventions and to apply dental sealants.

Methods

Using a stepped wedge design, 16 dental clinics were cluster randomized, and 680 providers and staff were exposed to a deliberative engagement process that included an introductory session, workbook, facilitated small group deliberative forum, and post-forum survey. Forum participants were assigned to forums to ensure diverse role representation. Mechanisms of action examined included sharing voice and diversity of opinion. Three months after each clinic's forum, the clinic manager was interviewed about implementation interventions deployed. There were 98 clinic-months in the non-intervention period and 101 clinic-months in the intervention period.

Results

Compared with providers and staff in small clinics, providers and staff in medium and large clinics more strongly agreed that their clinic should adopt two of the three proposed implementation interventions targeting the first barrier and one of the two proposed implementation interventions targeting the second barrier. Compared with the non-intervention period, in the intervention period providers did not place more sealants on occlusal non-cavitated carious lesions. Survey respondents reported sharing both promotive and prohibitive voice. From the beginning to the end of the forums, most forum participants did not change their opinions about the possible implementation interventions. At the end of the forums, there was no significant within-group variability in implementation interventions endorsed.

Conclusions

Deliberative engagement intervention may help clinic leadership identify implementation interventions when there is a challenging problem, a network of semi-autonomous clinics, and autonomous providers within those clinics. It remains to be determined whether there is a range of perspectives within clinics.

Barriers to Optimal Surgical Antimicrobial Prophylaxis for Methicillin-Resistant Staphylococcus aureus-Colonized Patients at an Australian Tertiary Teaching Hospital

Background: Surgical antimicrobial prophylaxis (SAP) is a leading indication for antibiotic use in Australian hospitals with established high rates of inappropriate prescribing. Optimal administration of SAP for patients at high risk of methicillin-resistant Staphylococcus aureus (MRSA) infections presents additional complexities. A greater understanding of barriers to optimal SAP in this cohort is required to inform targeted antimicrobial stewardship strategies, optimize SAP, and reduce the rate of surgical site infections (SSIs). Methods: A multiple-choice questionnaire appraising knowledge and barriers to optimal SAP was electronically distributed to key stakeholders. Data from the questionnaire were collated and analyzed using Survey Monkey^® (Momentive Inc., San Mateo, CA) data analysis tools. Results: Eighty-three persons provided full or partial responses to the questionnaire. There were 19% of respondents who considered MRSA colonization status of patients to be only "somewhat important" when selecting appropriate SAP. Additionally, 62% of responses did not correctly identify the appropriate SAP regimen for patients who are colonized with MRSA. Several barriers to optimal SAP were identified including poor understanding of SAP guidelines, lack of timely identification of patients confirmed to be colonized with MRSA, inaccurate documentation of antibiotic and surgical start times, and limitations of the current operating room management software program. Conclusions: The high level of engagement from most key stakeholders demonstrates accountability and an overall desire to improve SAP. Barriers identified in this audit should be considered by facilities wishing to optimize compliance with SAP guidelines and consequently reduce SSIs, in particular for patients who are at high risk of MRSA infections.

Exploring veterinarians' behaviour relating to antibiotic use stewardship on Irish dairy farms using the COM-B model of behaviour change

Employing a theoretical model of human behaviour (COMB), the current study explores the factors influencing veterinarians' engagement with antibiotic use stewardship on Irish dairy farms. One-to-one semi structured interviews were carried out by telephone with 12 veterinarians whose daily work focused on dairy cattle. A thematic analysis approach was undertaken. The identified themes and sub-themes were then mapped to the COM-B model. This study identified challenges faced by veterinarians when trying to prescribe responsibly which included lack of training to encourage farmer behaviour change, issues with laboratory testing, pressures from farmers to prescribe antimicrobials, concern for animal welfare and farmers going elsewhere for prescriptions. Having a good knowledge of AMR, peers as an advice source, potential financial benefits for farmers as a result of reduced antimicrobial costs and accepting a shared responsibility for AMR, facilitate veterinarians in their role as antimicrobial stewards. The barriers and facilitators identified as influencing veterinarians' capability, opportunity and motivation to responsibly prescribe antimicrobials formed the basis for a number of practical recommendations which should be considered by advisory and policy making teams. Recommendations include; continuous training for veterinarians on AMR and alternatives to overcome the barriers faced when trying to promote reduced AMU, veterinarian peer support groups to improve confidence in their knowledge and decision making to minimise the effect of client pressures/expectations, setting up collaborative farmer and veterinarian working groups to promote a transparent working relationship and the development of affordable and efficient diagnostic and susceptibility testing.

Vancomycin prescribing and therapeutic drug monitoring: Challenges of real clinical practice

BACKGROUND

Vancomycin prescription and monitoring guidelines have been reported to be poorly followed by various centers.

AIMS

Identifying barriers to compliance with vancomycin dosing and therapeutic drug monitoring guidelines (TDM) and possible ways to enhance compliance based on the healthcare providers' (HCPs) perspective.

METHODS

A qualitative study based on semi-structured interviews with HCP (physicians, pharmacists, and nurses) was conducted at two Jordanian Teaching Hospitals. Interviews were audio-recorded and analyzed through thematic analysis. The COREQ criteria for qualitative research were utilized to report the study findings.

RESULTS

A total of 34 HCPs were interviewed. HCP perceived several factors as barriers to guideline recommendation compliance. Such factors included negative perception towards prescription guidelines, lack of knowledge regarding TDM guidelines, the hierarchy of medication management, work pressure, and ineffective communication among healthcare providers. Potential strategies to optimize guidelines adaptation included providing HCPs with more training and decision support tools in addition to activating the role of clinical pharmacists.

CONCLUSIONS

The main barriers to guideline recommendations uptake were identified. Interventions should address those barriers related to the clinical environment, including enhancing interprofessional communication related to vancomycin prescription and TDM, reducing workload and providing support systems, promoting educational and training programs, in addition to adopting guidelines suitable for the local environment.

Implementation of an antimicrobial stewardship program in the Australian private hospital system: qualitative study of attitudes to antimicrobial resistance and antimicrobial stewardship

BACKGROUND

Antimicrobial Stewardship (AMS) is a key method to tackle antimicrobial resistance (AMR). In Australia, private hospitals have a higher rate of inappropriate prescribing and non-compliance with antimicrobial guidelines, yet this phenomenon is poorly described. Private hospitals make up 49% of hospitals in Australia, making it vital to understand AMS in this setting.

METHODS

This study aimed to explore capabilities, opportunities and motivations for AMR and AMS with stakeholders at an Australian private hospital, and identify barriers and enablers 5 years post-implementation of an AMS program comparing with pre-implementation findings. A mixed-methods study was performed, involving three focus groups with stakeholders. All doctors, nurses and pharmacists at the hospital were invited to complete a survey on their experiences with and awareness of AMR, AMS and antimicrobial prescribing.

RESULTS

Thirteen staff took part in the focus groups, 100 staff responded to the survey. Staff understood the importance of the AMS program, but active engagement was low. Staff felt more thorough feedback and monitoring could improve prescribing behaviour, but acknowledged difficulty in private hospitals in changing habits of staff who valued autonomy in making prescribing decisions. Half of respondents felt the current AMS restrictions should continue. Executive engagement may be needed to drive system changes across a complex network.

CONCLUSION

AMS awareness increased post-implementation, but staff remained sceptical of its benefits. Engagement and education of medical consultants regarding local benefits of AMS must improve. Enhanced understanding of feedback provision, methods for engagement, and advocacy from leadership will ensure success and longevity for the program.

Examining drivers of self-harm guideline implementation by general practitioners: A qualitative analysis using the theoretical domains framework

OBJECTIVES

This study aimed to (1) examine barriers and enablers to General Practitioners' (GP) use of National Institute for Health and Care Excellence (NICE) guidelines for self-harm and (2) recommend potential intervention strategies to improve implementation of them in primary care.

DESIGN

Qualitative interview study.

METHODS

Twenty-one telephone interviews, semi-structured around the capabilities, opportunities and motivations model of behaviour change (COM-B), were conducted with GPs in the United Kingdom. The Theoretical Domains Framework was employed as an analytical framework. Using the Behaviour Change Wheel, Behaviour Change Techniques (BCTs), intervention functions and exemplar interventions were identified.

RESULTS

GPs valued additional knowledge about self-harm risk assessments (knowledge), and communication skills were considered to be fundamental to high-pressure consultations (cognitive and interpersonal skills). GPs did not engage with the guidelines due to concerns that they would be a distraction from patient cues about risk during consultations (memory, attention and decision processes), and perceptions that following the guidance is difficult due to time pressures and lack of access to mental health referrals (environmental context and resources). Clinical uncertainty surrounding longer term care for people that self-harm, particularly patients that are waiting for or cannot access a referral, drives GPs to rely on their professional judgement over the guidance (beliefs about capabilities).

CONCLUSIONS

Three key drivers related to information and skill needs, guideline engagement and clinical uncertainty need to be addressed to support GPs to be able to assess and manage self-harm. Five intervention functions and ten BCT groups were identified as potential avenues for intervention design.

ACOI Surgical Site Infections Management Academy (ACOISSIMA)

Background:

Surgical site infections (SSIs) are the most common cause of healthcare-associated infections in surgical patients. Many SSIs may be preventable if simple measures are respected. Despite evidence supporting the effectiveness of evidence-based practices in Infection Prevention and Control, many surgeons fail to implement them.

Methods:

To clarify the key issues in the prevention of SSIs, an expert panel designated by the board of directors of Associazione Chirurghi Ospedalieri Italiani—Italian Surgical Association (ACOI) convened in Rome, Italy, on 16 December 2021, for a consensus conference.

Results:

The expert panel approved 11 evidence-based statements regarding the prevention of SSIs. A article was drafted and reviewed by the expert panel, finally obtaining this document that represents the executive summary of the consensus.

Conclusions:

The document aims to disseminate best practices among Italian surgeons and summarizes the ACOI recommendations for the prevention of SSIs.

Tipping the balance: A systematic review and meta-ethnography to unfold the complexity of surgical antimicrobial prescribing behavior in hospital settings

Surgical specialties account for a high proportion of antimicrobial use in hospitals, and misuse has been widely reported resulting in unnecessary patient harm and antimicrobial resistance. We aimed to synthesize qualitative studies on surgical antimicrobial prescribing behavior, in hospital settings, to explain how and why contextual factors act and interact to influence practice. Stakeholder engagement was integrated throughout to ensure consideration of varying interpretive repertoires and that the findings were clinically meaningful. The meta-ethnography followed the seven phases outlined by Noblit and Hare. Eight databases were systematically searched without date restrictions. Supplementary searches were performed including forwards and backwards citation chasing and contacting first authors of included papers to highlight further work. Following screening, 14 papers were included in the meta-ethnography. Repeated reading of this work enabled identification of 48 concepts and subsequently eight overarching concepts: hierarchy; fear drives action; deprioritized; convention trumps evidence; complex judgments; discontinuity of care; team dynamics; and practice environment. The overarching concepts interacted to varying degrees but there was no consensus among stakeholders regarding an order of importance. Further abstraction of the overarching concepts led to the development of a conceptual model and a line-of-argument synthesis, which posits that social and structural mediators influence individual complex antimicrobial judgements and currently skew practice towards increased and unnecessary antimicrobial use. Crucially, our model provides insights into how we might ‘tip the balance’ towards more evidence-based antimicrobial use. Currently, healthcare workers deploy antimicrobials across the surgical pathway as a safety net to allay fears, reduce uncertainty and risk, and to mitigate against personal blame. Our synthesis indicates that prescribing is unlikely to change until the social and structural mediators driving practice are addressed. Furthermore, it suggests that research specifically exploring the context for effective and sustainable quality improvement stewardship initiatives in surgery is now urgent.

Investigation of factors influencing inpatient antibiotic prescribing decisions in the Veterans' Health Administration

To investigate factors that influence antibiotic prescribing decisions, we interviewed 49 antibiotic stewardship champions and stakeholders across 15 hospitals. We conducted thematic analysis and subcoding of decisional factors. We identified 31 factors that influence antibiotic prescribing decisions. These factors may help stewardship programs identify educational targets and design more effective interventions.

Antibiotic Prophylaxis in Torso, Maxillofacial, and Skin Traumatic Lesions: A Systematic Review of Recent Evidence

Use of antibiotic prophylaxis (AP) in trauma patients is a common practice. However, considering the increasing rates of antibiotic resistance, AP use should be questioned and limited only to specific cases. We performed a systematic review of recent literature (from year 2000), aiming to summarize the state of the art on efficacy and appropriateness of AP in patients with traumatic injuries of torso, maxillofacial complex and skin (including burns). Twenty-six articles were selected. In thoracic trauma, AP could be useful in reducing infective complications in tube thoracostomy for penetrating trauma. In maxillo-facial trauma, AP could find a role in the peri-operative trauma setting in the case of a graft or prosthetic implant. In abdominal trauma, there is a lack of consensus on the definition of contamination, infection, antibiotic therapy, and prophylaxis. In burned patients, routine AP is not suggested. In the case of human bites to the extremities, AP could find an indication. Future studies should focus on the subcategories of patients at higher risk of infection, identifying those who would benefit from AP. Attention to antimicrobial stewardship and guidelines focused on AP in trauma are required, to reduce antibiotic abuse, and increase quality research.

Antibiotic Prophylaxis Prescribing Practice in Head and Neck Tumor Resection and Free Flap Reconstruction

Background

Adherence to guidelines for antibiotic prophylaxis is often poor and is an important target for antimicrobial stewardship programs. Prescribing audits that suggested poor adherence to guidelines in a plastic surgery department led to a targeted education program to bring antibiotic prescriptions in line with hospital guidelines. We reviewed whether this intervention was associated with changed perioperative prescribing and altered surgical outcomes, including the rate of surgical site infections, specifically looking at clean-contaminated head and neck tumor resections with free flap reconstruction.

Methods

A retrospective cohort study was performed on 325 patients who underwent clean-contaminated head and neck tumor resection and free flap reconstruction from January 1, 2013, to February 19, 2019. Patients were divided into 2 groups, those before (pre-intervention) and after (postintervention) the education campaign. We analyzed patient demographic and disease characteristics, intraoperative and postoperative factors, and surgical outcomes.

Results

Patients pre-intervention were prescribed longer courses of prophylactic antibiotics (median [interquartile range], 9 [8] vs 1 [1]; P < .001), more topical chloramphenicol ointment (21.82% vs 0%; P < .001), and more oral nystatin (36.9% vs 12.2%; P < .001). Patients postintervention had higher rates of recipient infections (36.11% vs 17.06%; P < .001) and donor site infections (6.94% vs 1.19%; P = .006).

Conclusions

Following the education campaign, patients were prescribed shorter courses of prophylactic antibiotics, more of the recommended cefazolin-metronidazole regimen, and fewer topical antibiotics. However, patients also had a higher rate of surgical site infections.

Surgical Antibiotic Prophylaxis in an Era of Antibiotic Resistance: Common Resistant Bacteria and Wider Considerations for Practice

The increasing incidence of antimicrobial resistance (AMR) presents a global crisis to healthcare, with longstanding antimicrobial agents becoming less effective at treating and preventing infection. In the surgical setting, antibiotic prophylaxis has long been established as routine standard of care to prevent surgical site infection (SSI), which remains one of the most common hospital-acquired infections. The growing incidence of AMR increases the risk of SSI complicated with resistant bacteria, resulting in poorer surgical outcomes (prolonged hospitalisation, extended durations of antibiotic therapy, higher rates of surgical revision and mortality). Despite these increasing challenges, more data are required on approaches at the institutional and patient level to optimise surgical antibiotic prophylaxis in the era of antibiotic resistance (AR). This review provides an overview of the common resistant bacteria encountered in the surgical setting and covers wider considerations for practice to optimise surgical antibiotic prophylaxis in the perioperative setting.

The Effect of Pharmacist-Led Intervention on Surgical Antibacterial Prophylaxis (SAP) at an Orthopedic Unit

Perioperative antibiotic use is a common reason for antibiotic misuse. Evidence suggests that adherence to SAP guidelines may improve outcomes. The purpose of this study was to analyze the impact of pharmacist-led antibiotic stewardship interventions on SAP guideline compliance. The study was conducted at an Orthopedic Department of a tertiary care medical center. SAP compliance and antibiotic exposure in the pre-intervention and intervention period was compared using chi-square, Fisher exact, and Mann-Whitney tests, as appropriate. Prophylactic antibiotic use in orthopedic joint arthroplasties (overall guideline adherence: agent, dose, frequency, duration), clinical outcomes (length of stay-LOS, number of surgical site infections-SSIs), antibiotic exposure and direct antibiotic costs were compared between pre-intervention and intervention periods. Significant improvement in mean SAP duration (by 42.9%, 4.08 ± 2.08 vs. 2.08 ± 1.90 days, p ˂ 0.001), and overall guideline adherence regarding antibiotic use (by 56.2%, from 2% to 58.2%, p ˂ 0.001) were observed. A significant decrease was observed in antibiotic exposure in SAP (by 41%, from 6.07 ± 0.05 to 3.58 ± 4.33 DDD/patient, p ˂ 0.001), average prophylactic antibiotic cost (by 54.8%, 9278.79 ± 6094.29 vs. 3598.16 ± 3354.55 HUF/patient), and mean LOS (by 37.2%, from 11.22 ± 6.96 to 7.62 ± 3.02 days, p < 0.001); and a slight decrease in the number of confirmed SSIs was found between the two periods (by 1.8%, from 3% to 1.2%, p = 0.21). Continuous presence of the clinical pharmacist led to significant improvement in SAP guideline adherence, which was accompanied by decreased antibiotic exposure and cost.

Antimicrobial stewardship in Australia: the role of qualitative research in programme development

Antimicrobial stewardship (AMS) in Australia is supported by a number of factors, including enabling national policies, sectoral clinical governance frameworks and surveillance programmes, clinician-led educational initiatives and health services research. A One Health research programme undertaken by the National Centre for Antimicrobial Stewardship (NCAS) in Australia has combined antimicrobial prescribing surveillance with qualitative research focused on developing antimicrobial use-related situational analyses and scoping AMS implementation options across healthcare settings, including metropolitan hospitals, regional and rural hospitals, aged care homes, general practice clinics and companion animal and agricultural veterinary practices. Qualitative research involving clinicians across these diverse settings in Australia has contributed to improved understanding of contextual factors that influence antimicrobial prescribing, and barriers and facilitators of AMS implementation. This body of research has been underpinned by a commitment to supplementing 'big data' on antimicrobial prescribing practices, where available, with knowledge of the sociocultural, technical, environmental and other factors that shape prescribing behaviours. NCAS provided a unique opportunity for exchange and cross-pollination across the human and animal health programme domains. It has facilitated synergistic approaches to AMS research and education, and implementation of resources and stewardship activities. The NCAS programme aimed to synergistically combine quantitative and qualitative approaches to AMS research. In this article, we describe the qualitative findings of the first 5 years.

The "Torment" of Surgical Antibiotic Prophylaxis among Surgeons

Surgical antibiotic prophylaxis (SAP) is one of the peri-operative measures for preventing surgical site infections (SSIs). Its goal is to counteract the proliferation of bacteria in the surgical site during intervention in order to reduce the risk of SSIs. SAP should be administered for surgical interventions where the benefit expected (prevention of SSIs) is higher compared to the risk (serious side effects, such as acute kidney injury, Clostridioides difficile infection, and the spread of antimicrobial resistance). In prescribing SAP, surgeons should have both the awareness necessary “to handle antibiotics with care”, and the knowledge required to use them appropriately.

Surgical antibiotic prophylaxis administration practices

SETTING

A referral hospital in Kavre, Nepal.

OBJECTIVES

To assess 1) compliance with National Antibiotic Treatment Guidelines (NATG), specifically, whether the administration of surgical antibiotic prophylaxis (SAP) (initial dosing and redosing) was in compliance with NATG for patients who were and were not eligible, and 2) development of surgical site infections (SSIs) among patients who underwent surgery in the Department of General Surgery (July-December 2019).

DESIGN

This was a retrospective cohort analysis.

RESULTS

The analysis included 846 patients, of which 717 (85%) patients were eligible for SAP and 129 (15%) were ineligible. Of those eligible, 708 (99%) received the initial dose; while 65 (50%) of the ineligible did not receive any dose. Of those who received the initial dose, 164 (23%) were eligible for redosing. Of these, only 23 (14%) received at least one redosing and 141 (86%) did not receive it. Overall compliance with NATG was achieved in 75% (632/846) of patients. SSIs occurred in 23 (3%) patients, 8 (35%) of whom did not have SAP administered according to NATG.

CONCLUSION

A relatively high overall compliance with NATG for SAP administration was reported. Recommendations were made to improve compliance among those who were ineligible for SAP and those who were eligible for redosing.

Physician-reported barriers and challenges to antibiotic prescribing in surgical prophylaxis: a structured systematic review

Objectives

The purpose of the study is to identify and analyse the barriers in surgical procedures where antibiotic dissipation is habitual.

Methods

Extensive literature search is carried out using different electronic databases (PubMed, Europe PMC, PLoS and Google Scholar) between January 2000 and December 2020. The articles were selected purely based on the inclusion criteria. Only qualitative and cross-sectional studies were selected to reduce the risk of bias. The JBI and AXIS checklists were used to assessed the quality of the enrolled articles. Data extractions were done by using a predesigned standardized data collection form.

Key findings

A total of 2067 articles were electronically retrieved but only 14 articles met the eligibility criteria. About 15 902 healthcare professionals (HCPs) with an average response rate of 64.7% were pooled for evidence synthesis. The majority of respondents (50%) discussed different barriers in their practice site for surgical antibiotic prophylaxis (SAP) administration. Barriers were categorized into four themes: lack of guideline availability and knowledge, lack of adherence to guidelines, lack of guideline knowledge and adherence and physician perceptions or off-label practices. A total of 723 (56.3%) out of 1282 HCPs from nine different studies reported a lack of adherence to guidelines during the perioperative process. The majority of respondents in three studies, 318 (82%) out of 386 HCPs, reported that physicians’ perceptions play a crucial role in prescribing SAP during surgeries.

Conclusion

This study concluded that the barriers within the practice site play a decisive role in SAP optimization and therefore all HCPs are recommended to maintain local/standard guidelines and adhere to them while prescribing SAP.

Perceptions of surgeons on surgical antibiotic prophylaxis use at an urban tertiary hospital in Tanzania

BACKGROUND

Surgical Site Infections are a major cause of morbidity and mortality among operated patients. In spite of the accessibility of universal and national guidelines for surgical prophylaxis, recent studies surveying the present routine of prophylaxis have demonstrated overutilization of a wide range antibacterial medication for a single patient. Few studies have shown qualitatively factors influencing this and perceptions of surgeons on surgical antibiotic prophylaxis use. Unfortunately, none of these studies have been done in Tanzania.

OBJECTIVE

To describe the perceptions of surgeons on surgical antibiotic prophylaxis use at an urban tertiary hospital.

METHODS

A qualitative study involving in-depth interviews with surgeons was conducted in English by the primary investigator. The interviews were audio-recorded and transcribed verbatim. Systematic text condensation by Malterud was used for data analysis.

FINDINGS

Fourteen surgeons and obstetrics and gynaecologists participated. Their perceptions were summarized into three main categories: Inadequate data to support practice; one who sees the patient decides the antibiotic prophylaxis; prolonged antibiotic use for fear of unknown. The participants perceived that choice of antibiotic should be based on local hospital data for bacterial resistance pattern, however the hospital guidelines and data for surgical site infection rates are unknown. Fear of getting infection and anticipating complications led to prolonged antibiotics use.

CONCLUSION

The study provides an understanding of surgical antibiotic prophylaxis use and its implementation challenges. This was partly expressed by unavailability of local data and guidelines to enhance practice. To improve this, there is a need of guidelines that incorporates local resistance surveillance data and enhanced antibiotic stewardship programmes. A strong consideration should be placed into ways to combat the fears of surgeons for complications, as these significantly affect the current practise with use of surgical antibiotic prophylaxis.

Barriers and facilitators to implementing evidence based bleeding management in Australian Cardiac Surgery Units: a qualitative interview study analysed with the theoretical domains framework and COM-B model

Background

Bleeding during cardiac surgery is a common complication that often requires the transfusion of blood products. The combination of bleeding and blood product transfusion incrementally increases adverse outcomes including infection and mortality. Following bleeding management guideline recommendations could assist with minimising risk but adherence is not high, and the cause for lack of adherence is not well understood. This study aimed to identify barriers and facilitators to practicing and implementing evidenced-based intra-operative, bleeding management in Australian cardiac surgery units.

Methods

We used a qualitative descriptive design to conduct semi-structured interviews with Australian cardiac surgeons, anaesthetists and perfusionists. The Theoretical Domains Framework (TDF) was utilised to guide interviews and thematically analyse the data. Categorised data were then linked with the three key domains of the COM-B model (capability, opportunity, motivation - behaviour) to explore and understand behaviour.

Results

Seventeen interviews were completed. Nine of the 14 TDF domains emerged as significant. Analysis revealed key themes to improving capability included, standardisation, monitoring, auditing and feedback of data and cross discipline training. Opportunity for change was improved with interpersonal and interdepartmental collaboration through shared goals, and more efficient and supportive processes allowing clinicians to navigate unfamiliar business and financial models of health care. Results suggest as individuals, clinicians had the motivation to make change and healthcare organisations have an obligation and a responsibility to partner with clinicians to support change and improve goal directed best practice.

Conclusion

Using a theory-based approach it was possible to identify factors which may be positively or negatively influence clinicians ability to implement best practice bleeding management in Australian cardiac surgical units.

Barriers-enablers-ownership approach: a mixed methods analysis of a social intervention to improve surgical antibiotic prescribing in hospitals

OBJECTIVES

To assess an intervention for surgical antibiotic prophylaxis (SAP) improvement within surgical teams focused on addressing barriers and fostering enablers and ownership of guideline compliance.

DESIGN

The Queensland Surgical Antibiotic Prophylaxis (QSAP) study was a multicentre, mixed methods study designed to address barriers and enablers to SAP compliance and facilitate engagement in self-directed audit/feedback and assess the efficacy of the intervention in improving compliance with SAP guidelines. The implementation was assessed using a 24-month interrupted time series design coupled with a qualitative evaluation.

SETTING

The study was undertaken at three hospitals (one regional, two metropolitan) in Australia.

PARTICIPANTS

SAP-prescribing decisions for 1757 patients undergoing general surgical procedures from three health services were included. Six bimonthly time points, pre-implementation and post implementation of the intervention, were measured. Qualitative interviews were performed with 29 clinical team members. SAP improvements varied across site and time periods.

INTERVENTION

QSAP embedded ownership of quality improvement in SAP within surgical teams and used known social influences to address barriers to and enablers of optimal SAP prescribing.

RESULTS

The site that reported senior surgeon engagement showed steady and consistent improvement in prescribing over 24 months (prestudy and poststudy). Multiple factors, including resource issues, influenced engagement and sites/time points where these were present had no improvement in guideline compliance.

CONCLUSIONS

The barriers-enablers-ownership model shows promise in its ability to facilitate prescribing improvements and could be expanded into other areas of antimicrobial stewardship. Senior ownership was a predictor of success (or failure) of the intervention across sites and time periods. The key role of senior leaders in change leadership indicates the critical need to engage other specialties in the stewardship agenda. The influence of contextual factors in limiting engagement clearly identifies issues of resource distributions/inequalities within health systems as limiting antimicrobial optimisation potential.

Prolonged antibiotic prophylaxis use in elective orthopaedic surgery - a cross-sectional analysis

Purpose

Surgical antibiotic prophylaxis (SAP) prevents surgical site infections (SSI). In orthopaedic surgery, the use of prolonged SAP (PSAP) has been reported in daily routine, despite guidelines advising against it. Therefore, we asked: What is the proportion of PSAP use, defined as administration of SAP ≥24 h after elective orthopaedic surgery? Are there patient- and surgery-related predictors of PSAP use?

Methods

This cross-sectional analysis investigated 1292 patients who underwent elective orthopaedic surgery including total joint arthroplasties at one Swiss centre between 2015 and 2017. Patient comorbidities, surgical characteristics and occurrence of SSI at 90 days in PSAP group were compared to the SAP group (< 24 h post-operative).

Results

PSAP use was 12% (155 of 1292). Patient-related factors associated with PSAP compared to the SAP group included older age (63 vs. 58y; p < 0.001), higher BMI (29 vs. 27 kg/m²; p < 0.001), ASA classification ≥3 (31% vs. 17%; p < 0.001) and lung disease (17% vs. 9%; p = 0.002). Surgery-related factors associated with PSAP were use of prosthetics (62% vs. 45%; p < 0.001), surgery of the knee (65% vs. 25%; p < 0.001), longer surgery duration (87 vs. 68 min; p < 0.001) and presence of drains (90% vs. 65%; p < 0.001). All four SSI occurred in the SAP group (0 vs. 4; p = 1.0). Surgeons administered PSAP with varying frequencies; proportions ranged from 0 to 33%.

Conclusion

PSAP use and SSI proportions were lower than reported in the literature. Several patient- and surgery-related factors associated with PSAP use were identified and some were potentially modifiable. Also, experienced surgeons seemed to implement differing approaches regarding the duration of SAP administration.

Factors that influence adherence to surgical antimicrobial prophylaxis (SAP) guidelines: a systematic review

BACKGROUND

Despite the extensive research that has been conducted to date, practice often differs from established guidelines and will vary between individuals and organisations. It has been noted that the global uptake of local and international surgical antimicrobial prophylaxis (SAP) guidelines is poor with limited research investigating factors that affect guideline adherence. The purpose of this systematic review was to determine the reported barriers and enablers to the adherence of SAP guidelines.

METHODS

A search of the literature was performed using four electronic databases (CINAHL, EMBASE, PubMed and SCOPUS) for articles published in the English language from January 1998 to December 2018. Articles were included if they were solely related to SAP and discussed the barriers or enablers to SAP guideline adherence. Articles that assessed the adherence to a range of infection control measures or discussed adherence to antibiotic treatment guidelines rather than SAP guidelines were excluded from this review. Barriers and enablers were mapped to the Theoretical Domains Framework (TDF). The Mixed Methods Appraisal Tool was used to assess the quality of included studies.

RESULTS

A total of 1489 papers were originally retrieved, with 48 papers meeting the eligibility criteria. Barriers and enablers were mapped to 11 out of 14 TDF domains: knowledge, skills, social/professional role and identity, beliefs about capabilities, beliefs about consequences, reinforcement, memory, attention and decision processes, environmental context and resources, social influences, emotion and behavioural regulation. Barriers were further categorised into personal or organisational barriers, while enablers were arranged under commonly trialled interventions.

CONCLUSIONS

There are numerous factors that can determine the uptake of SAP guidelines. An identification and understanding of these factors at a local level is required to develop tailored interventions to enhance guideline adherence. Interventions, when used in combination, can be considered as a means of improving guideline use.

Enhancing Healthcare Decision-Making Process: Findings from Orthopaedic Field

In the healthcare field, the decision-making process is part of the broad spectrum of “clinical reasoning”, which is recognised as the whole process by which a physician decides about patients’ treatments and cares. Several clinicians’ intrinsic variables lead to this decisional path. Little is known about the inference of these variables in triggering biases in decisions about the post-discharge period in the surgical field. Accordingly, this research aims to understand if and how cognitive biases can affect orthopaedists in decision-making regarding the follow-up after knee and hip arthroplasty. To achieve this goal, an interview-based explorative case study was run. Three key-decisional orthopaedic surgeons were interviewed through a quality control tool aimed at monitoring the causes and effects of cognitive distortions. Coherently with the literature, eight biases come to light. All the interviewees agree on the presence of four common biases in orthopaedic surgery (Affect heuristic, Anchoring, Halo effect, Saliency). The other biases (Groupthink, Availability, Overconfidence, Confirmation), instead, depending on specific physicians’ intrinsic variables; namely: (i) working experience; (ii) working context. This finding contributes to the debate about the application of cognitive tools as leverage for improving the quality of clinical decision-making process and, indirectly, enhancing better healthcare outcomes.

Identifying targets for improvement using a nationally standardized survey: Surgical antimicrobial prophylaxis in orthopedic surgery

BACKGROUND

Surgical antimicrobial prophylaxis (SAP) is commonly administered in orthopedic procedures. Research regarding SAP appropriateness for specific orthopedic procedures is limited and is required to facilitate targeted orthopedic prescriber behavior change.

OBJECTIVES

To describe SAP prescribing and appropriateness for orthopedic procedures in Australian hospitals.

DESIGN, SETTING, AND PARTICIPANTS

Multicenter, national, quality improvement study with retrospective analysis of data collected from Australian hospitals via Surgical National Antimicrobial Prescribing Survey (Surgical NAPS) audits from January 1, 2016, to April 15, 2019, were analyzed.

METHODS

Logistic regression identified hospital, patient and surgical factors associated with appropriateness. Adjusted appropriateness was calculated from the multivariable model. Additional subanalyses were conducted on smaller subsets to calculate the adjusted appropriateness for specific orthopedic procedures.

RESULTS

In total, 140 facilities contributed to orthopedic audits in the Surgical NAPS, including 4,032 orthopedic surgical episodes and 6,709 prescribed doses. Overall appropriateness was low, 58.0% (n = 3,894). This differed for prescribed procedural (n = 3,978, 64.7%) and postprocedural doses (n = 2,731, 48.3%). The most common reasons for inappropriateness, when prophylaxis was required, was timing for procedural doses (50.9%) and duration for postprocedural prescriptions (49.8%). The adjusted appropriateness of each orthopedic procedure group was low for procedural SAP (knee surgery, 54.1% to total knee joint replacement, 74.1%). The adjusted appropriateness for postprocedural prescription was also low (from hand surgery, 40.7%, to closed reduction fractures, 68.7%).

CONCLUSIONS

Orthopedic surgical specialties demonstrated differences across procedural and postprocedural appropriateness. The metric of appropriateness identifies targets for quality improvement and is meaningful for clinicians. Targeted quality improvement projects for orthopedic specialties need to be developed to support optimization of antimicrobial use.

Factors associated with antimicrobial choice for surgical prophylaxis in Australia

Background

Cefazolin is the most commonly recommended antimicrobial for surgical antimicrobial prophylaxis (SAP). However, the Australian Surgical National Antimicrobial Prescribing Survey revealed a wide range of antimicrobials prescribed for SAP. Inappropriate use of broad-spectrum antimicrobials is associated with increased patient harm and is a posited driver for antimicrobial resistance.

Objectives

To describe patient, hospital and surgical factors that are associated with appropriateness of the top five prescribed antimicrobials/antimicrobial classes for procedural SAP.

Methods

All procedures audited from 18 April 2016 to 15 April 2019 in the Surgical National Antimicrobial Prescribing Survey were included in the analysis. Estimated marginal means analyses accounted for a range of variables and calculated a rate of adjusted appropriateness (AA). Subanalyses of the top five audited antimicrobials/antimicrobial classes identified associations between variables and appropriateness.

Results

A total of 12 419 surgical episodes with 14 150 prescribed initial procedural doses were included for analysis. When procedural SAP was prescribed, appropriateness was low (57.7%). Allergy status, surgical procedure group and the presence of prosthetic material were positively associated with cefazolin and aminoglycoside appropriateness (P < 0.05). There were no significant positive associations with glycopeptides and third/fourth-generation cephalosporins. The use of broad-spectrum antimicrobials was the most common reason for inappropriate choice (67.9% of metronidazole to 83.3% of third/fourth-generation cephalosporin prescriptions).

Conclusions

Various factors influence appropriateness of procedural SAP choice. Identification of these factors provides targets for antimicrobial stewardship interventions, e.g. procedures where surgeons are regularly prescribing broad-spectrum SAP. These can be tailored to address local hospital prescribing practices.

Impact of industry 4.0 to create advancements in orthopaedics

Scientists and health professional are focusing on improving the medical sciences for the betterment of patients. The fourth industrial revolution, which is commonly known as Industry 4.0, is a significant advancement in the field of engineering. Industry 4.0 is opening a new opportunity for digital manufacturing with greater flexibility and operational performance. This development is also going to have a positive impact in the field of orthopaedics. The purpose of this paper is to present various advancements in orthopaedics by the implementation of Industry 4.0. To undertake this study, we have studied the available literature extensively on Industry 4.0, technologies of Industry 4.0 and their role in orthopaedics. Paper briefly explains about Industry 4.0, identifies and discusses the major technologies of Industry 4.0, which will support development in orthopaedics. Finally, from the available literature, the paper identifies twelve significant advancements of Industry 4.0 in orthopaedics. Industry 4.0 uses various types of digital manufacturing and information technologies to create orthopaedics implants, patient-specific tools, devices and innovative way of treatment. This revolution is to be useful to perform better spinal surgery, knee and hip replacement, and invasive surgeries.

Antibiotic prescribing in surgery: A clinically and socially complex problem in Australia

Surgical prophylaxis is a common indication for antimicrobial use in Australian hospitals with demonstrated poor rates of appropriateness. Ongoing analysis of the Surgical National Antimicrobial Prescribing Survey and exploration of influences on antimicrobial prescribing decisions can help identify clinical and behavioural issues that contribute to problematic antimicrobial use. Triangulation of quantitative and qualitiatve data supports the development of surgical antimicrobial stewardship, i.e., quality improvement initiatives for the optimisation of surgical antimicrobial prophylaxis. Such initiatives should be developed and implemented at both local and national levels to ensure that they remain effective and sustainable.
