Adherence to Surgical Site Infection Guidelines in Italian Cardiac Surgery Units

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.

Appropriateness of Surgical Antimicrobial Prophylaxis Practices in Australia

IMPORTANCE

Surgical antimicrobial prophylaxis (SAP) is a common indication for antibiotic use in hospitals and is associated with high rates of inappropriateness.

OBJECTIVE

To describe the SAP prescribing practices and assess hospital, surgical, and patient factors associated with appropriate SAP prescribing.

DESIGN, SETTING, AND PARTICIPANTS

Multicenter, national, quality improvement study with retrospective analysis of data collected from Australian hospitals via Surgical National Antimicrobial Prescribing Survey audits from January 1, 2016, to June 30, 2018. Data were analyzed using multivariable logistic regression. Crude estimates of appropriateness were adjusted for factors included in the model by calculating estimated marginal means and presented as adjusted-appropriateness with 95% confidence intervals.

MAIN OUTCOMES AND MEASURES

Adjusted appropriateness and factors associated with inappropriate prescriptions.

RESULTS

A total of 9351 surgical episodes and 15 395 prescriptions (10 740 procedural and 4655 postprocedural) were analyzed. Crude appropriateness of total prescriptions was 48.7% (7492 prescriptions). The adjusted appropriateness of each surgical procedure group was low for procedural SAP, ranging from 33.7% (95% CI, 26.3%-41.2%) for dentoalveolar surgery to 68.9% (95% CI, 63.2%-74.5%) for neurosurgery. The adjusted appropriateness of postprocedural prescriptions was also low, ranging from 21.5% (95% CI, 13.4%-29.7%) for breast surgery to 58.7% (95% CI, 47.9%-69.4%) for ophthalmological procedures. The most common reason for inappropriate procedural SAP was incorrect timing (44.9%), while duration greater than 24 hours was the most common reason for inappropriate postprocedural SAP (54.3%).

CONCLUSIONS AND RELEVANCE

High rates of inappropriate procedural and postprocedural antimicrobial use were demonstrated across all surgical specialties. Reasons for inappropriateness, such as timing and duration, varied according to the type of SAP and surgical specialty. These findings highlight the need for improvement in SAP prescribing and suggest potential targeted areas for action.

Evaluating the implementability of Antibiotic Surgical Prophylaxis guidelines

BACKGROUND

Current Australian data highlight guideline noncompliant prescribing of antimicrobials for surgical prophylaxis. The study aim was to evaluate the implementability of the Australian national surgical prophylaxis (SAP) guidelines to identify facilitators for and barriers to compliance.

METHODS

Key stakeholders appraised the surgical prophylaxis guidelines using the GuideLine Implementability Appraisal (GLIA) tool. Questions with 100% agreement for the response 'Yes' were identified as facilitators and those with 100% agreement for 'No', a barrier. Questions that did not receive 100% agreement, but had a majority (40-60%) 'Yes' or 'No' consensus were considered as borderline facilitators and barriers respectively.

RESULTS

Ten appraisals were completed. Guideline recommendations were rated as easily identifiable and concise and were thus facilitators for implementation. The ability to measure guideline adherence and outcomes, and recommendations that were consistent with guideline user abilities and beliefs were also identified as facilitators. Borderline facilitators related to the clarity of the recommendations and whether they were explicit in what to do and in what circumstances. Evidence quality underpinning recommendations (validity), inflexibility of recommendations (flexibility) and the lack of patient data at the point of use (computability) were identified as borderline barriers to implementation. No recommendation reached agreement as being a barrier.

CONCLUSION

The GLIA appraisal demonstrated overall implementability of the current Australian national surgical prophylaxis guidelines. Facilitators (i.e., measurability) and borderline facilitators highlight strengths of the current guideline. Borderline barriers (i.e., validity, flexibility and computability) may negatively impact upon implementability. Guideline developers should consider these dimensions to optimise guideline uptake and consequently patient care.

Interface transition checklists in spinal surgery

ISSUE

Recently, quality tools have been promoted to improve patient safety and process efficiency in healthcare. While surgeons primarily focused on surgical issues, like infection rates or implant design, we introduced pre-admission and preoperative checklists in the early 2000s.

INITIAL ASSESSMENT

To assess the efficiency of these tools in a neurosurgical department, we performed a survey of all spinal instrumentation patients operated in 2011 (n = 147). The results revealed several problems.

CHOICE OF SOLUTION

We consequently redesigned the checklists accompanied by flanking measures, such as written  and online accessible standards. Furthermore, the staff was trained to use the updated quality tools.

IMPLEMENTATION

The measures were implemented in 2012.

EVALUATION

Results were re-evaluated in a second survey in 2013 (n = 162). We found that the use of pre-admission checklists significantly increased from 47 to 96%, while the use of preoperative checklists significantly decreased from 86 to 75%. Within the same period, the quality and completeness of the checklists did, however, increase, so that in 2013, 43% of the patients had a completely processed preoperative checklist, compared to 29% in 2011.

LESSONS LEARNED

The introduction of checklists alone did not in itself guarantee an improved workflow. The introduction must be accompanied by other measures, like written standards and regular training of employees. Otherwise, the positive effect wears off quickly. Nevertheless, we could show that the stringent application of quality tools can induce a sustainable change. Our data further suggest that the clear and traceable delegation of responsibilities is of high importance.

Adherence to international and national recommendations for the prevention of surgical site infections in Italy: results from an observational prospective study in elective surgery

BACKGROUND

An observational prospective study of the perioperative procedures for prevention of surgical site infections (SSIs) was carried out in a tertiary referral teaching hospital in Liguria, Italy, to evaluate their adherence to international and national standards.

METHODS

A 1-month survey was performed in all surgical departments, monitored by turns by trained survey teams. Data regarding presurgical patient preparation and intraoperative infection control practices were collected.

RESULTS

A total of 717 elective interventions were actively monitored in 703 patients who underwent surgery. Hair-shaving was performed mainly using a razor (92%) by the nurses (72.8%) on the day before the operation (83.5%). All of the patients showered, either with a common detergent (87%) or with an antiseptic solution (13%). Antimicrobial prophylaxis was administered properly in 75.7% of the patients at induction of anaesthesia; however, according to current Italian guidelines, inappropriate prophylaxis was provided in 55.2% patients. Appropriate antisepsis of the incision area was done in 97.4% of the operations, and nearly 90% of the interventions lasted less than the respective 75th percentile. The doors of the operating theatres were mostly open during the duration of the operation in 36.3% of the cases.

CONCLUSIONS

This review of infection control policies identified significant opportunities for improving the safety and the quality of routine surgical practice.

Adherence to guidelines for antibiotic prophylaxis in surgery patients in German hospitals: a multicentre evaluation involving pharmacy interns

BACKGROUND AND AIM

Surgical site infections (SSIs) are associated with a high morbidity, mortality and healthcare costs. The prevention of SSIs is based on a combination of preoperative preparation, surgical techniques, perioperative antibiotic prophylaxis (PAP) and postoperative wound care. Despite an abundance of evidence demonstrating the effectiveness of antimicrobials to prevent SSIs, the use of antimicrobial prophylaxis in this clinical setting is associated with inappropriate timing and selection and excessive duration of administration. To date, pharmacy interns (PIs) have not been involved in this process. The aim of this study was to evaluate feasibility of involving PIs in monitoring adherence to the guidelines for antibiotic prophylaxis in surgery patients.

METHODS

The study was conducted in seven hospitals in Germany within the framework of the project "Pharmacy interns on the ward" (P-STAT2). Twenty-seven PIs participated, either from either May to October 2008 or from November 2008 to April 2009. Each patient admitted to the participating wards was consecutively monitored. PIs documented the antibiotic prophylaxis and checked the adherence with the hospital ward's PAP guidelines taking both the choice of antibiotic drug and the duration of PAP into account. The costs of antibiotics, personnel and material were calculated in cases of non-adherence with guidelines.

RESULTS

This is the first time that PIs were involved in monitoring antibiotic prophylaxis guidelines. A total of 6,167 patients were enrolled (mean age 58.3 ± 19.6 years; 47.1% male); of these, 5,064 patients underwent surgery and were ultimately available for evaluation. Guidelines for antibiotic prophylaxis were followed in 70.7% of the cases.

CONCLUSIONS

The study revealed that many patients do not receive the appropriate antibiotic prophylaxis despite the fact that guidelines are in place. Based on these results, we conclude that PIs may play an important role in antibiotic prophylaxis management.
