Adherence to guidelines of antibiotic prophylactic use in surgery: a prospective cohort study in North West Bank, Palestine

Antibiotic utilization at an orthopedic inpatient department in a large governmental hospital in the north of the West Bank, Palestine; a retrospective observational study

BACKGROUND

Studies evaluating the patterns of antibiotic consumption are becoming increasingly necessary as a result of the increased use of antibiotics and development of antibiotic resistance globally. This study aimed to evaluate the use of antibiotics in in terms of both quantity and quality at the largest surgical hospital in the north of the West Bank, Palestine.

METHODS

An observational retrospective study with a total population sampling method was conducted to collect data from the inpatients of the orthopedic departments of a large governmental hospital in the northern West Bank, Palestine. The data were collected from patients' files and evaluated using the anatomical therapeutic chemical and defined daily dose (ATC/DDD) methodology, and the drug utilization 90% (DU90%) index. The ATC/DDD methodology, designed by the World Health Organization (WHO), as a well-trusted and standardized tool that allows measuring and comparing antibiotic utilization across different contexts. Antibiotic prescriptions were classified using the World Health Organization Access, Watch and Reserve classification (WHO AWaRe).

RESULTS

Of the 896 patients who were admitted to the hospital in the year 2020 and included in the study, 61.9% were males, and 38.1% were females. The percentage of patients who received antibiotics was 97.0%, and the overall antibiotic usage was 107.91 DDD/100 bed days. The most commonly prescribed antibiotic was cefazolin (50.30 DDD/100 bed days), followed by gentamicin (24.15 DDD/100 bed days) and ceftriaxone (17.35 DDD/100 bed days). The DU90% segment comprised four different agents. Classification of antibiotics according to the WHO AWaRe policy revealed that 75.9% of antibiotics were prescribed from the access list.

CONCLUSION

This study comes as part of the efforts exerted to combat the growing problem of antibiotic resistance in Palestine. Our results showed that the consumption of antibacterial agents in the orthopedic unit at a large governmental hospital in Palestine was relatively high. The results of this study provide valuable insights for the decision-makers to create policies aimed at regulating antibiotic prescriptions. This study also aims to provide a look into the antibiotic prescription patterns, offering a clearer understanding of the current situation of antibiotic consumption in Palestine. It also emphasizes the need for antibiotic stewardship and surveillance programs.

A hidden gem in multidisciplinary antimicrobial stewardship: a systematic review on bedside nurses' activities in daily practice regarding antibiotic use

Background

Antimicrobial stewardship (AMS), the set of actions to ensure antibiotics are used appropriately, is increasingly targeted at all those involved in the antimicrobial pathway, including nurses. Several healthcare organizations have issued position statements on how bedside nurses can be involved in AMS. However, it remains unclear how nurses, in reality, contribute to appropriate antibiotic use.

Objectives

To systematically search the literature to describe the activities bedside nurses perform regarding antibiotic use in daily clinical practice, in relation to the activities proposed by the aforementioned position statements.

Methods

We searched MEDLINE, Embase, CINAHL and grey literature until March 2021. Studies were included if they described activities regarding antibiotic use performed by bedside nurses. Methodological rigour was assessed by applying the Mixed Method Appraisal Tool.

Results

A total of 118 studies were included. The majority of the proposed nurses' activities were found in daily practice, categorized into assessment of clinical status, collection of specimens, management of antimicrobial medication, prompting review and educating patient and relatives. Nurses may take the lead in these clinical processes and are communicators in all aspects of the antimicrobial pathway. Patient advocacy appears to be a strong driver of bedside nurses' activities.

Conclusions

Nurses' activities are already integrated in the day-to-day nursing practice and are grounded in the essence of nursing, being a patient advocate and showing nursing leadership in safeguarding the antimicrobial treatment process. An essential element of the nursing role is communication with other stakeholders in the patient-centred antimicrobial pathway. Educating, engaging and empowering nurses in this already integrated role, could lead to a solid, impactful nursing contribution to AMS.

Prophylactic Antibiotics in Hip Fracture Surgery: A Randomized Prospective Study

Introduction Hip fracture surgeries constitute a large portion of orthopedic surgeries, and infective complications are one of the most severe and devastating sequels following fixations or replacements. Preoperative antibiotic prophylaxis is an important means to control SSI. Thus, we set out to assess the impact of a single dose versus three doses of antibiotics on surgical site infections in patients undergoing hip surgery. Materials and methods A randomized controlled trial was conducted at the Department of Orthopaedics, The Indus Hospital, Karachi, Pakistan. All patients admitted for hip fracture surgery who met the inclusion criteria were enrolled and divided into two groups. One group (Group A) was given a single dose of antibiotics preoperatively, and the other (Group B) was given three doses, one preoperatively and two postoperatively. Patients were assessed for wound condition and signs of infection. Data were entered and analyzed using SPSS version 21.0. The chi-square test was applied to assess the significant association between both the groups and SSI. A significant statistical association was noted when the P value was found to be <0.05. Results The study included 62 patients, with the majority of them being females (n=33; 53.2%). The mean age of the patients was 60.5±15.1 years. Only three (4.8%) patients developed SSI. No statistically significant association was detected between surgical site infections and the two antibiotic regimens being administered after controlling for the confounders. Conclusion There was no statistical relationship between surgical site infections with a single dose versus three doses of antibiotics in patients undergoing hip surgery.

Surgical site infection and antimicrobial prophylaxis prescribing profile, and its determinants among hospitalized patients in Northeast Ethiopia: a hospital based cross-sectional study

The inappropriate use of surgical antimicrobial prophylaxis is a common cause for increased risk of morbidity and mortality from surgical site infection in patients who underwent surgical procedures. The study aimed to evaluate surgical antimicrobial prophylaxis prescribing patterns, Surgical Site Infection (SSI), and its determinants in the surgical ward of Debre Berhan Comprehensive Specialized Hospital, northeast Ethiopia. A prospective cross-sectional study was conducted from October 1st 2022 to January 31st, 2023. Data collected from patient medical record cards and patient interviews were entered and analyzed using SPSS V26.0. The determinants of surgical site infection were determined from the multivariable logistic regression. P-value ≤ 0.05 was considered statistically significant. Ceftriaxone (70.5%) followed by a combination of ceftriaxone with metronidazole (21.90%) was the most frequently used prophylactic antibiotic. One hundred fifty-nine (78%) of patients were exposed to inappropriately used prophylactic antimicrobials and 62.2% of these were exposed to inappropriately selected antibiotics. One hundred twenty-six (61.9%) patients developed Surgical Site Infection (SSI). Duration of procedure longer than an hour and inappropriate use of antimicrobial prophylaxiswere the independent predictors for the occurrence of surgical site infections. Patients whose operation was lasted in longer than an hour were 3.39 times more likely to develop SSI compared to those whose operation was completed in less than an hour, AOR = 3.39 (95% CI: 1.24-9.30). Similarly, controlling the effect of other covariate variables, individuals who were given inappropriate antimicrobial prophylaxis were 6.67 times more likely to develop SSI compared to those given appropriate prophylaxis, AOR = 6.67 (95% CI: 1.05-42.49). The high rate of SSI requires due attention from clinicians as well as health policymakers. Duration of surgical procedure greater than an hour and inappropriate antimicrobial prophylaxis use was the independent predictor of surgical site infections.

Surgical Antibiotic Prophylaxis Administration Improved after introducing Dedicated Guidelines: A Before-and-After Study from Dhulikhel Hospital in Nepal (2019-2023)

(1) Background: Surgical antibiotic prophylaxis (SAP) is important for reducing surgical site infections. The development of a dedicated hospital SAP guideline in the Dhulikhel Hospital was a recommendation from a baseline study on SAP compliance. Compliance with this new guideline was enhanced through the establishment of a hospital committee, the establishment of an antibiotic stewardship program and the funding and training of healthcare professionals. Using the baseline and a follow-up study after introducing dedicated hospital SAP guidelines, we compared: (a) overall compliance with the SAP guidelines and (b) the proportion of eligible and non-eligible patients who received initial and redosing of SAP; (2) Methods: A before-and-after cohort study was conducted to compare SAP compliance between a baseline study (July 2019-December 2019) and a follow-up study (January 2023-April 2023); (3) Results: A total of 874 patients were in the baseline study and 751 in the follow-up study. Overall SAP compliance increased from 75% (baseline) to 85% in the follow-up study (p < 0.001). Over 90% of those eligible for the initial dose of SAP received it in both studies. Inappropriate use for those not eligible for an initial dose was reduced from 50% to 38% (p = 0.04). For those eligible for redosing, this increased from 14% to 22% but was not statistically significant (p = 0.272); (4) Conclusions: Although there is room for improvement, introduction of dedicated SAP guidelines was associated with improved overall SAP compliance. This study highlights the role of operational research in triggering favorable interventions in hospital clinical care.

Healthcare Cost and Outcomes Associated With Surgical Site Infection and Patient Outcomes in Low- and Middle-Income Countries

Surgical site infection (SSI) is a growing global concern. The principal explanation for this is its adverse clinical outcomes, such as morbidity and mortality. However, the link between the economic burden of SSIs and patient outcomes needs to be sufficiently characterized. This review aims to describe the financial implications of SSIs on patient outcomes in low- and middle-income countries (LMIC). Despite the heterogeneity in study designs from multiple LMIC countries, there is a significant correlation between SSI-associated healthcare costs from increased length of stay (LOS), readmissions, reoperations, and adverse patient outcomes. This varies based on the size, degree of infection, or other patient comorbidities. SSIs are much more prevalent in LMICs. The additional financial burden incurred in managing SSIs reinforces the need to prioritize practicing interventions to prevent this complication, which resource-limited health institutions are unequipped to do and consequently have significant adverse patient outcomes.

Double blind randomized controlled trial for subjects undergoing surgery receiving surgical antimicrobial prophylaxis at tertiary hospital: the clinical pharmacist's interventions

Background

A surgical site infection (SSI) has significant clinical, humanistic and economic consequences. Surgical antimicrobials prophylaxis (SAP) is a reliable standard to prevent SSIs.

Objective

The objective was to test that the clinical pharmacist's interventions may facilitate the implementation of SAP protocol and subsequent reduction of SSIs.

Methods

This was double blinded randomized controlled interventional hospital-based-study at Khartoum State-Sudan. A total of 226 subjects underwent general surgeries at four surgical units. Subjects were randomized to interventions and controls in a (1:1) ratio where patient, assessors and physician were blinded. The surgical team has received structured educational and behavioral SAP protocol mini courses by way of directed lecturers, workshops, seminars and awareness campaigns delivered by the clinical pharmacist. The clinical pharmacist provided SAP protocol to the interventions group. The outcome measure was the primary reduction in SSIs.

Results

There were (51.8%, 117/226) females, (61/113 interventions versus 56/113 controls), and (48.2%, 109/226) males (52 interventions and 57 controls). The overall rate of SSIs was assessed during 14 days post-operatively and was documented in (35.4%, 80/226). The difference in adherence to locally developed SAP protocol regarding the recommended antimicrobial was significant (P <0.001) between the interventions group (78, 69%) and the controls group (59, 52.2%). The clinical pharmacist's implementation of the SAP protocol revealed significant differences in SSIs with reduction in SSIs from 42.5% to 25.7% versus the controls group from 57.5% to 44.2% respectively, P = 0.001 between the interventions group and the controls group respectively.

Conclusion

The clinical pharmacist's interventions were very effective in sustainable adherence to SAP protocol and subsequent reduction in SSIs within the interventions group.

Antibiotic Usage in Surgical Prophylaxis: A Retrospective Study in the Surgical Ward of a Governmental Hospital in Riyadh Region

Antibiotic prophylaxis is used to decrease the bacterial load in the wound to assist the natural host defenses in preventing the occurrence of surgical site infections. The present study aimed to investigate trends in using antibiotic prophylaxis in the surgical ward of a governmental hospital in the Riyadh Region and included collecting data concerning the use of antibiotic prophylaxis from medical electronic records. During 2020, most of the surgical patients received systemic antibiotics (82.40%). The most prescribed antibiotics were ceftriaxone (28.44%) and metronidazole (26.36%). The study also found that most of the patients received antibiotics for seven days or for five days, and only 1.08% of the patients received antibiotics appropriately for a maximum of one day. The present study showed that there was a major problem in selecting the correct antibiotic and in the duration of its use compared with the recommendations of the surgical prophylaxis guideline that was issued by the Saudi Ministry of Health. Thus, there is an urgent need to improve the adherence to the recommendations of surgical antibiotic prophylaxis guidelines in order to reduce the occurrence of negative consequences.

OUP accepted manuscript

Background

In daily hospital practice, antibiotic therapy is commonly prescribed for longer than recommended in guidelines. Understanding the key drivers of prescribing behaviour is crucial to generate meaningful interventions to bridge this evidence-to-practice gap.

Objectives

To identify behavioural determinants that might prevent or enable improvements in duration of antibiotic therapy in daily practice.

Methods

We systematically searched PubMed, Embase, PsycINFO and Web of Science for relevant studies that were published between January 2000 and August 2021. All qualitative, quantitative and mixed-method studies in adults in a hospital setting that reported determinants of antibiotic therapy duration were included.

Results

Twenty-two papers were included in this review. A first set of studies provided 82 behavioural determinants that shape how health professionals make decisions about duration; most of these were related to individual health professionals’ knowledge, skills and cognitions, and to professionals’ interactions. A second set of studies provided 17 determinants that point to differences in duration regarding various pathogens, diseases, or patient, professional or hospital department characteristics, but do not explain why or how these differences occur.

Conclusions

Limited literature is available describing a wide range of determinants that influence duration of antibiotic therapy in daily practice. This review provides a stepping stone for the development of stewardship interventions to optimize antibiotic therapy duration, but more research is warranted. Stewardship teams must develop complex improvement interventions to address the wide variety of behavioural determinants, adapted to the specific pathogen, disease, patient, professional and/or hospital department involved.

Surgical antimicrobial prophylaxis in open reduction internal fixation procedures at a metropolitan hospital in Australia: a retrospective audit

Background

Open reduction internal fixation (ORIF) of closed fractures is a required indication for surgical antimicrobial prophylaxis (SAP). Guidelines contain recommendations on how best to prescribe SAP, however, adherence to SAP guidelines remains suboptimal. The Australian Therapeutic Guidelines: Antibiotic v16 (updated April 2019) advocates for single dose prophylaxis for ORIF procedures. There is a paucity of information on how SAP is prescribed for ORIF of closed fractures in Australian hospitals. The aim of this study was to identify prescribing practice and to evaluate guideline adherence pre- and post-guideline update.

Methods

A retrospective audit was conducted for patients undergoing an ORIF of closed fractures at a metropolitan teaching hospital in a 6-month period during 2018 (pre-guideline update) and 2019 (post-guideline update). Data were collected on prescribing practice (perioperative antibiotics prescribed, dose, time and route of administration and duration of prophylaxis) and compared to SAP recommendations in Therapeutic Guidelines: Antibiotic v15 (2018) and v16 (2019). Descriptive statistics and Chi square tests were used to report categorical variables. Binary logistic regression was used to identify factors associated with guideline adherence. A p-value < 0.05 was deemed statistically significant.

Results

Data were collected for a total of 390 patients (n = 185, 2018; n = 205, 2019). Cefazolin was the most commonly prescribed antibiotic as per guideline recommendations, with variable, yet appropriate doses observed across the two audit periods. While 78.3% of patients received SAP for the correct duration in 2018, only 20.4% of patients received single dose prophylaxis in 2019. Overall adherence to guidelines was 63.2% in the 2018, and 18.0% in the 2019 audit periods respectively. Patient age was significantly associated with an increase in overall guideline adherence, while lower limb fractures, an American Society of Anesthesiologists (ASA) score of 3 and emergency admissions were associated with decreased overall adherence to SAP guidelines.

Conclusion

Adherence to guidelines was greater with v15 (2018) compared with v16 (2019). Patient factors, including limb fracture site and ASA score, had little impact on guideline adherence. Further research is required to understand what influences guideline adherence in the orthopaedic setting.

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.

Assessment of Antibiotic Prophylaxis in Surgical Patients and Association Factors at Thu Duc District Hospital, Ho Chi Minh City, Vietnam in 2018

Surgical antibiotic prophylaxis (SAP) is considered an important interventional tool for antimicrobial resistance. Guideline compliance was poor across different countries and this results in an inappropriate and overuse of antibiotics. The study was cross-sectional, combining qualitative and quantitative. The Research used the MOH’s Antibiotic Preventive Medicine Guidelines as the standard to verify surgical preventive treatment compliance from patient medical records. Research performed on 373 medical records with surgical indications. The study was conducted from January to June 2019. Data were entered using Epidata software and processed by SPSS software version 19.0. Analysis: calculating OR for related factors. The compliance rate of using prophylactic antibiotics was 83.1%. There is a relationship between the type of incision, the length of time surgery, and compliance with surgical prophylactic use of antibiotics (P < .05). Barriers to adherence to prophylactic antimicrobial therapy include: overcrowding patients, health-care workers “broad-spectrum antibiotic use habits, and health-care workers” views on surgical and muscle environment, the material was not completely sterilized.

Key Issues Surrounding Appropriate Antibiotic Use for Prevention of Surgical Site Infections in Low- and Middle-Income Countries: A Narrative Review and the Implications

BACKGROUND

There is a concern with the growing use of antimicrobials across countries increasing antimicrobial resistance (AMR) rates. A key area within hospitals is their use for the prevention of surgical site infections (SSI) with concerns with timing of the first dose, which can appreciably impact on effectiveness, as well as duration with extended prophylaxis common among low- and middle-income countries (LMICs). This is a concern as extended duration increases utilization rates and AMR as well as adverse events. Consequently, there is a need to document issues of timing and duration of surgical antibiotic prophylaxis (SAP) among LMICs together with potential ways forward to address current concerns.

METHODS

Narrative review of timings and duration of SAP among LMICs combined with publications documenting successful approaches to improve SAP to provide future direction to all key stakeholder groups.

RESULTS

There were documented concerns with the timing of the first dose of antibiotics, with appropriate timing as low as 6.7% in Egypt, although as high as 81.9% in Turkey. There was also an extensive duration of SAP, ranging from long duration times in all patients in a study in Nigeria with a mean of 8.7 days and 97% of patients in Egypt to 42.9% of patients in Pakistan and 35% in Turkey. Successful interventions to improve SAP typically involved multiple approaches including education of all key stakeholder groups, monitoring of usage against agreed guidelines,as well as quality targets. Multiple approaches typically improved timing and duration as well as reduced costs. For instance, in one study appropriateness increased from 30.1% to 91.4%, prolonged duration reduced to 5.7% of patients, and mean costs of antibiotics decreased 11-fold.

CONCLUSION

There are considerable concerns with the timing and duration of SAP among LMICs. Multiple interventions among LMICs can address this providing future directions.

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.

Assessment of implementation of antibiotic stewardship program in surgical prophylaxis at a secondary care hospital in Ras Al Khaimah, United Arab Emirates

Antibiotic overuse is a major factor for causing antibiotic resistance globally. However, only few studies reported the implementation and evaluation of antimicrobial stewardship programs in Gulf Cooperation Council. This study was conducted within 8-months periods to evaluate the effect of the newly implemented antibiotic stewardship program on improving the prescribing practice of surgical antibiotic prophylaxis in a secondary care hospital in the United Arab Emirates by releasing local hospital guidelines. The data of 493 in patients were documented in the predesigned patient profile form and the prescribing practice of surgical antibiotic prophylaxis for clean and clean-contaminant surgical procedures was compared and analyzed two months’ prior (period A) and post (period B) the implementation of antibiotic stewardship program. The 347 patient’s data (PD) were analyzed during period A and 146 PD during period B. The prescription of piperacillin/tazobactam was decreased from 2.4% from all surgical prophylaxis antibiotic orders in period A to 0% in period B. The appropriateness of the antibiotic therapy was found to differ non significantly for the selection of prophylactic antibiotic (p = 0.552) and for the timing of first dose administration (p = 0.061) between A and B periods. The total compliance was decreased non significantly (P = 0.08) from 45.3 to 40.2%. Overall, the guidelines have improved the prescribing practice of antibiotics prior to surgery. However, further improvement can be achieved by initiating educational intervention via cyclic auditing strategy.

Compliance with antibiotic prophylaxis guidelines in caesarean delivery: a retrospective, drug utilization study (indication-prescription type) at an Ecuadorian hospital

BACKGROUND

Preoperative antibiotic prophylaxis is essential for preventing surgical site infection (SSI). The aim of this study was to evaluate compliance with international and local recommendations in caesarean deliveries carried out at the Obstetrics and Gynaecology Service of the Ambato General Hospital, as well as any related health and economic consequences.

METHODS

A retrospective indication-prescription drug utilization study was conducted using data from caesarean deliveries occurred in 2018. A clinical pharmacist assessed guidelines compliance based on the following criteria: administration of antibiotic prophylaxis, antibiotic selection, dose, time of administration and duration. The relationship between the frequency of SSI and other variables, including guideline compliance, was analysed. The cost associated with the antibiotic used was compared with the theoretical cost considering total compliance with recommendations. Descriptive statistics, Odds Ratio and Pearson Chi Square were used for data analysis by IBM SPSS Statistics version 25.

RESULTS

The study included 814 patients with an average age of 30.87 ± 5.50 years old. Among the caesarean sections, 68.67% were emergency interventions; 3.44% lasted longer than four hours and in 0.25% of the deliveries blood loss was greater than 1.5 L. Only 69.90% of patients received preoperative antibiotic prophylaxis; however, 100% received postoperative antibiotic treatment despite disagreement with guideline recommendations (duration: 6.75 ± 1.39 days). The use of antibiotic prophylaxis was more frequent in scheduled than in emergency caesarean sections (OR = 2.79, P = 0.000). Nevertheless, the timing of administration, antibiotic selection and dose were more closely adhered to guideline recommendations. The incidence of surgical site infection was 1.35%, but tended to increase in patients who had not received preoperative antibiotic prophylaxis (OR = 1.33, P = 0.649). Also, a significant relationship was found between SSI and patient age (χ2 = 8.08, P = 0.036). The mean expenditure on antibiotics per patient was 5.7 times greater than that the cost derived from compliance with international recommendations.

CONCLUSIONS

Surgical antibiotic prophylaxis compliance was far below guideline recommendations, especially with respect to implementation and duration. This not only poses a risk to patients but leads to unnecessary expenditure on medicines. Therefore, this justifies the need for educational interventions and the implementation of institutional protocols involving pharmacists.

Preoperative Antibiotic Prophylaxis in Elective Minor Surgical Procedures among Adults in Southern Italy

Little is known regarding the factors associated with surgical antibiotic prophylaxis (SAP) compliance in elective minor surgery. The purposes of this cross-sectional study were to identify the frequency of inappropriate SAP administration and to understand the characteristics associated with such inappropriateness in a sample of elective minor surgical procedures. The study was performed between May and July 2019 among a random sample of patients aged 18 years and older in seven public hospitals randomly selected in the Campania and Calabria Regions of Italy. Globally, only 45% of SAP approaches were deemed completely in accordance with the evidence-based guidelines. Patients with an ordinary admission, those who underwent local anesthesia, those receiving plastic and reconstructive and ophthalmology surgery, and those who had not received a prosthetic implant were more likely to receive an appropriate SAP approach; those receiving obstetrics, gynecological, and urological surgical procedures were less likely than those who underwent abdominal, vascular, and breast surgery. The course of antibiotic prophylaxis was not consistent with the guidelines in 48.5% procedures with one or more reasons for inappropriateness. Appropriate time of the SAP administration was more frequently observed in patients who were older, those with a Charlson comorbidity index of 0, those who did not receive a prosthetic implant, and those receiving plastic and reconstructive surgery; it was less likely in patients receiving obstetrics, gynecological, and urological surgeries compared with those who underwent abdominal, vascular, and breast surgery. Aspects of SAP that need to be improved are molecule choice, time of administration, and specific surgical procedures. Hospital managers should involve surgeons and anesthesiologists in initiatives tailored to optimize SAP prescribing.

Nurse role and contribution to antimicrobial stewardship: An integrative review

AIM

To examine existing published literature regarding nurses and antimicrobial stewardship, and their potential role and contribution, to identify what is known, to evaluate methodologies used in published research, and to review and integrate findings to inform practice and future priorities for research.

DESIGN

Integrative review.

METHODOLOGY

The approach to this review was informed by Whittemore and Knafl's integrative review methodology. Electronic databases were searched for papers published since the start of the database to November 2019, with abstracts available, related to humans and published in English. Papers were included regardless of practice setting (acute, aged, and primary care) and if they were research based, included nurses as participants and reported specifically on results from nurses or that had implications for nursing practice. Excluded were conference abstracts, and papers focussed solely on nurse prescriber, nurse practitioner, or nurse manager roles.

RESULTS

Fifty-two papers were included in the review. Identified themes were: i) nursing knowledge, learning needs and education; ii) nurse perceptions of the nursing role and motivations for involvement; iii) nursing brokerage and influence on information flow to and from patients; iv) nursing workflow, workload and workarounds; and v) nurse leadership. Methodological quality of the included papers varied, limiting transferability and applicability of findings for some of the included studies.

CONCLUSION

Formal inclusion of nurses in antimicrobial stewardship activities has been associated with improved nurse knowledge, nurse confidence, and in some cases improved clinical outcomes for patients. The review reinforces nursing values as a motivator of nursing actions, and reveals the complex yet significant influence of nurses on antimicrobial prescribing. Potential opportunities to enhance nurses' participation and contribution to antimicrobial stewardship include; formal acknowledgement of the nurse role, educating nurses so that they are aware of how they can contribute, collaborating with nurses in planning and implementing local stewardship activities, and ensuring nurse leaders are involved. However, evidence on this topic remains limited. Research is needed to facilitate greater understanding about the nature, scope and influence of the nurse role in antimicrobial stewardship, how nurses enact and carry out their role, and nurses' support needs. Tweetable abstract: Integrative review explores #nurse role in #antimicrobialstewardship. Nurse contribution, influence significant, but not well understood.

Toxic Effect of Vancomycin on Viability and Functionality of Different Cells Involved in Tissue Regeneration

To prevent infections local delivery of antibiotics is a useful tool. Especially in bone fractures, vancomycin impregnated bone cements are often used allowing high concentrations of antibiotics at the infection side without high serum concentrations. However, besides potential pathogens, cells involved in tissue regeneration may also be affected by the drug. We investigated the effect of vancomycin on the viability and functionality on osteoblasts, endothelial cells, fibroblasts and skeletal muscle cells. Our results show that the viability of all cells analyzed was reduced by vancomycin and that the observed effects were time and concentration dependent. The most pronounced toxic effect was detected on day three when even the lowest concentration of 0.01 mg/ml led to a significant decrease in proliferation compared to control. Functionality assays of osteoblasts and skeletal muscle cells revealed a sensitive reaction of the cells to the drug, indicating that vancomycin is toxic to these cells during the process of differentiation. These data suggest that the vancomycin administration is critical for cell survival and function. Therefore, the concentration of administered antibiotics needs to be carefully evaluated to find a balance between defense against pathogens and functionality of host cells and tissues.

Audit of pre-operative antibiotic prophylaxis usage in elective surgical procedures in two teaching hospitals, Islamabad, Pakistan: An observational cross-sectional study

An audit of the antibiotic prophylaxis in surgical procedures is the basic area of antimicrobial stewardship programme. The current research aimed to evaluate the adherence-proportion of the pre-operative antibiotic prophylaxis (PAP) practices in common elective surgical procedures. It was an eight-month (January 2017 to August 2017) observational cross-sectional patients’ treatment record-based study conducted at two tertiary care teaching hospitals of Islamabad, Pakistan. We investigated the three most commonly performed elective general surgical procedures at the hospitals in adults aged > 18 years with no previous infection or surgery. The required data were extracted from the medical charts. Current prescribing practices were compared with the standard prescribing guidelines. A total of 660 (Government Hospital (GH), n = 330 and Private Hospital (PH), n = 330) procedures were observed. The most commonly performed elective general surgical procedures were laparoscopic cholecystectomy 307/660 (46.5%), followed by direct inguinal hernia 197/660 (29.8%) and total thyroidectomy 156/660 (23.6%). Non-use of PAP was observed in 64/660 (9.7%) cases. PAP was given to 90.3% (n = 596/660) cases (300/330 (90.9%) patients in GH and 296/330 (89.7%) in PH; P = 0.599). Based on the existing guidelines, the choice of antibiotics was correct in only 4.2% (25/596) patients (10/300; 3.3% cases at GH and 15/296; 5% at PH). The appropriate use of antibiotics was significantly greater in direct inguinal hernia (n = 19/193; 9.8%) cases compared with that in total thyroidectomy (n = 4/152; 2.6%) and laparoscopic cholecystectomy (n = 2/251; 0.8%) cases; P = 0.001. Compliance to the timing was only 51% (n = 304/596) of the total patients received PAP which was significantly lower in GH 97/300 (32.3%) as compared with that in PH 207/296 (69.9%); P = 0.001. Administration timing of antibiotics was observed to be more appropriate in total thyroidectomy (n = 79/152; 51.9%) cases than in laparoscopic cholecystectomy (n = 130/251; 51.8%) and direct inguinal hernia (n = 95/193; 49.2%) cases; P = 0.001. The route and dose were appropriate in accordance with the guidelines in all cases (100%). Most of the patients received ceftriaxone, a third-generation cephalosporin that is no longer recommended by the latest international guidelines. The current analysis revealed an alarmingly poor adherence rate with the guidelines in the three elective surgical procedures at both hospitals. To improve the situation, training and awareness programs about the antimicrobial stewardship interventions on the institutional level may be valuable.

Prevalence of antimicrobial use and active healthcare-associated infections in acute care hospitals: a multicentre prevalence survey in Japan

OBJECTIVE

To determine the prevalence of antimicrobial drug use and active healthcare-associated infections (HAIs) and to evaluate the appropriateness of antimicrobial therapy in acute care hospitals in Japan.

DESIGN

A prospective multicentre cross-sectional study.

PARTICIPANTS

All hospitalised patients on a survey day.

MAIN OUTCOME MEASURES

The primary outcome was the proportion of patients receiving any antimicrobial agents. The secondary outcome was the proportion of patients with active HAIs. The reasons for antimicrobial drug use and appropriateness of antibiotic therapy were also investigated.

RESULTS

Eight hundred twenty eligible patients were identified. The median patient age was 70 years (IQR 55-80); 380 (46.3%) were women, 150 (18.3%) had diabetes mellitus and 107 (13.1%) were immunosuppressive medication users. The proportion of patients receiving any antimicrobial drugs was 33.5% (95% CI 30.3% to 36.8%). The proportion of patients with active HAIs was 7.4% (95% CI 5.6% to 9.2%). A total of 327 antimicrobial drugs were used at the time of the survey. Of those, 163 (49.8%), 101 (30.9%) and 46 (14.1%) were used for infection treatment, surgical prophylaxis and medical prophylaxis, respectively. The most commonly used antimicrobial drugs for treatment were ceftriaxone (n=25, 15.3%), followed by piperacillin-tazobactam (n=22, 13.5%) and cefmetazole (n=13, 8.0%). In the 163 antimicrobial drugs used for infection treatment, 62 (38.0%) were judged to be inappropriately used.

CONCLUSIONS

The prevalence of antimicrobial use and active HAIs and the appropriateness of antimicrobial therapy in Japan were similar to those of other developed countries. A strategy to improve the appropriateness of antimicrobial therapy provided to hospitalised patients is needed.

Evaluation of Antibiotic Prophylaxis and Discharge Prescriptions in the General Surgery Department

Introduction Although there are international guidelines for surgical antibiotic prophylaxis (SP), the use of inappropriate SP is still a common problem. Most studies investigated SP applications in clean and clean-contaminated cases. However, antibiotics in the discharge prescriptions of these cases have not been adequately investigated. In this study, we aimed to examine the antibiotics in SP applications and discharged prescriptions together and to find out the causes of inappropriate use. Materials and methods We retrospectively evaluated the data of patients admitted to our general surgery wards between 2014 and 2015. Patients with clean or clean-contaminated wound category operations were included. The patients were evaluated in terms of convenience of SP (choice of antibiotics, compliance with an indication for SP, timing of the first dose, SP>24 hours, and discharge prescription). In addition, to interpret the results, a questionnaire has been performed for the surgeons in the same clinics. Results A total of 1205 patients with clean and clean-contaminated wound class operation were enrolled in this study. The total accuracy rate of SP was 7.1%. SP application with the correct indication and timing of the first dose was compatible with guidelines: 55.6% and 81.9%, respectively. SP was applied >24 hours at 60.2% and antibiotic prescribing carried out after discharge at 80.6% of patients. According to questionnaire results, the use of SP over 24 hours and the prescription of antibiotics during discharge were: drain usage, hyperthermia, leukocytosis, surgeons feeling of comfort, avoidance of patients, and their relatives' reactions. Conclusion The total accuracy rate of SP rate was low in the present study and in surgeons prescribing the SP after discharge. In light of the present study, we suggest that discharge prescriptions should also be reviewed in clinics who have a high inappropriate surgical antibiotic prophylaxis rate.

Improving surgical antibiotic prophylaxis adherence and reducing hospital readmissions: a bundle of interventions including health information technologies

OBJECTIVES

Infection following orthopaedic surgery is a feared complication and an indicator of the quality of the hospital. Surgical antibiotic prophylaxis (SAP) guidelines are not always properly followed. Our aim was to describe and evaluate the impact of a multidisciplinary intervention on antibiotic prophylaxis adherence to hospital guidelines and 30-day postoperative outcomes.

METHODS

The study was carried out from January to May 2016 and consisted of creating a multidisciplinary team, updating institutional guidelines and embedding the recommendations in the computerised physician order entry system which is linked to dose and renal function alerts, educational activities and pharmaceutical bedside care of patients in the orthopaedic department. A prospective pre-post study was carried out in accordance with the Declaration of Helsinki. The following information was recorded: patient and surgery characteristics, adherence to SAP guidelines, surgical site infections, length of hospital stay and rate of readmission 30 days after discharge. Statistical analyses were performed using SPSS 18.0.

RESULTS

Eighty three orthopaedic patients of mean±SD age 68.2±17.0 years (44.6% male, 40 in the pre-intervention group and 43 in the intervention group) were included. Cefazolin was the recommended and most commonly administered antibiotic agent. In the intervention group, an improvement in global adherence to guidelines was achieved (76.7% vs 89.9%; p=0.039): antibiotic duration (75.0% vs 97.7%), correct dosage post-surgery (55.0% vs 76.7%), timing of administration (57.5% vs 72.1%), antibiotic pre-surgery prescription (92.5% vs 97.7%). Three surgical site infections were detected in the pre-intervention group and none in the intervention group (p>0.05). Length of hospital stay was reduced by 1 day and readmission decreased by 15% (p=0.038).

CONCLUSIONS

SAP is used in daily practice in most orthopaedic patients. The implementation of a multidisciplinary programme based on health technology improved the adherence to guidelines and appeared to reduce the readmission rate.

Antibiotic usage in surgical prophylaxis: A prospective observational study in the surgical ward of Nekemte referral hospital

Background

Surgical antimicrobial prophylaxis guidelines are considered as important interventional tools for antimicrobial resistance. Guideline compliance was poor across different countries and thus results in an inappropriate and overuse of antibiotics.

Objective

To evaluate the selection, timing and duration of prophylactic antibiotic administration among surgical patients in Nekmte referral hospital.

Method

Prospective, facility based cross-sectional study was conducted from 1^st April to 30^th June 2017. Data were collected using data abstraction format among surgical inpatients prescribed with surgical antibiotic prophylaxis. Surgical antimicrobial prophylaxis guidelines were used as data assessment protocols. SPSS version 21.0 was used for data entry and analysis. Descriptive statistics and binary logistic regression were used for analysis.

Results

The median age of the study participants was 35.0 (IQR: 25–50) years with the preponderance (58.8%) of male patients. The median hospitalization period was 8.0 (IQR: 5–11) days. Majority of the participants were from the general surgical ward (60.1%). About 43% of the procedures were clean. Most of the surgical cases were gastrointestinal (39.2%). Only 10.6% of the drug selections comply with American Society of Health-System Pharmacists guideline. Surprisingly, none of the selections were compliant to the national Standard Treatment Guideline of the country. About 84% of the study participants received ceftriaxone. Majority of the prophylactic antibiotics (75.8%) were administered for greater than 24 hours and above half (52.3%) of the antibiotics were administered preoperatively. Emergent surgery procedures (AOR = 2.89, 95% CI: (1.09–9.10) and being a male patient (AOR = 3.10, 95% CI: 1.07–8.98) were associated with inappropriate preoperative antibiotic administration. Patients admitted to the gynecology and obstetrics ward was less likely to receive surgical prophylaxis for greater than 24 hours (AOR = 0.07, 95% CI: 0.01–0.81).

Conclusion

Surgical antibiotic compliance was far below the guideline recommendation. Patients admitted in the gynecology and obstetrics ward were more likely to comply with the surgical antimicrobial prophylaxis duration recommendation. The timing was most likely to be inappropriate among male patients and patients on emergent surgery. Availability and awareness creation on the antibiotic drugs and the guidelines were important interventions recommended for appropriate surgical antimicrobial use.

Auditing and Improving Surgical Antibiotic Prophylaxis

BACKGROUND

There is extensive evidence of the efficacy of anti-microbial drugs in preventing infections from surgical efforts. Our objective was to describe the results obtained in our annual surgical antibiotic prophylaxis (SAP) audit in the years 2013-2017.

METHODS

This was a retrospective observational study of SAP in surgical procedures carried out between 2013 and 2017 in a tertiary-level hospital. We examined the results from the services of general surgery, vascular surgery, neurosurgery, the breast unit, otolaryngology, maxillofacial surgery, traumatology, urology, pediatric surgery, gynecology, and plastic surgery.

RESULTS

Establishment of six process quality indicators and their evaluation in the annual audit were carried out by the pharmacy service for approximately 500 operations. The indicators that had a high percentage of compliance were indication for SAP, choice of anti-microbial agent, dose and route of administration, and administration of an intra-operative dose when this was appropriate. In contrast, time of administration of the first dose and duration of prophylaxis had a worse percentage of compliance.

CONCLUSIONS

Compliance with the SAP protocols in our hospital is high. We consider that these better results are attributable to the establishment of quality indicators of SAP and to the annual audit that evaluates said indicators. Communication of the results obtained in the audit to the surgical services, which have as part of their objectives included in their management contracts compliance with said SAP protocols, encourages improvement. The use of prophylaxis kits is an improvement strategy that facilitates the correct choice of anti-microbial agent and prevents SAP from being prolonged inappropriately.

[Evaluation of surgical antibiotic prophylaxis in a Tunisian University Hospital]

Antibiotic prophylaxis (ATBP) is one of the specific measures for the prevention of surgical site infections, whose impact has been quantified in clean or clean-contaminated surgery. Our study aims to evaluate the conformity of ATBP practices and the adherence to the prescribing protocols adopted in our Hospital. We conducted a clinical audit retrospective observational study, evaluating antibiotic prophylaxis practices in our Hospital in the month of March 2015. The primary study endpoint was the overall compliance of the observed practices with the 5 major criteria defined by the French National Authority for Health (FNAH). We followed the guidelines of the French Society of Anesthesia and Intensive Care published in 2010. The study included 150 patients who had undergone surgery in the Department of General Surgery, Orthopaedics and Urology. The overall compliance rate was 33.3%. The compliance with each of the 5 major criteria defined by the FNAH was 74% for the indication; 84% for the time between injection and incision; 60% for the choice of ATB; 89.3% for the dose of the first injection and 72% for the duration of ATBP. The compliance was variable depending on the Department; better compliance was reported in the Department of Urology, in scheduled surgery and when the prescriber was an anesthetist-resuscitator. A global strategy including organization, education and restriction, could lead to a real improvement in the rate of compliance with ATBP practices. Successive audits should be carried out regularly in order to evaluate the impact of the undertaken actions.

How do professional relationships influence surgical antibiotic prophylaxis decision making? A qualitative study

BACKGROUND

Surgical antibiotic prophylaxis (SAP) is a critical area to optimize to reduce the escalation of antimicrobial resistance. This article explores the ways by which interpersonal relationships influence SAP decision making.

METHODS

Twenty surgeons and anesthetists participated in in-depth semistructured interviews on SAP prescribing. Results were analyzed using the framework approach.

RESULTS

Analysis revealed 3 ways by which interpersonal relationships influence SAP: relationship dynamics between the surgeon and the anesthetist determine appropriateness of SAP, particularly operative risk ownership; perceived hierarchies within, and between, surgical and anesthetist specialties influence antibiotic prescribing decisions; and surgical distance from the antimicrobial stewardship team, which influences use of antimicrobial stewardship principles.

CONCLUSIONS

Interventions to optimize SAP are more likely to be effective in enacting sustained change if they consider the interpersonal and social contexts, including issues of familiarity and cohesiveness, hierarchical patterns, and sense of place within a team. Significant relational dynamics in SAP decision making are centered around risk; that is, personal/reputational risk to different professional groups and ownership of risk for individual patient outcomes. Risk must therefore be considered for sustainable SAP optimization interventions.

Noncompliance with surgical antimicrobial prophylaxis guidelines: A Jordanian experience in cesarean deliveries

BACKGROUND

Surgical site infections are common, especially in developing countries. Nevertheless, up to 60% of surgical site infections can be prevented with appropriate perioperative care, which includes among other measures using suitable surgical antimicrobial prophylaxis (SAP).

METHODS

After a short interview with patients and retrospective review of medical charts, compliance with 6 SAP parameters was assessed for appropriateness; those parameters are indication, choice, dose, time of administration, intraoperative redosing interval, and duration of prophylaxis in 1,173 operations.

RESULTS

Overall compliance was poor; nevertheless, certain components showed high compliance rates, such as indication and choice of antibiotics. The most frequent error noted was extended administration of prophylactic antibiotics, which was observed in 88.2% of the study population. Emergency operations were associated with a lower risk of noncompliance in administering the correct dose at the correct time (odds ratio, 0.63; 95% confidence interval, 0.47-0.83 and odds ratio, 0.21; 95% confidence interval, 0.14-0.3, respectively). On the other hand, women who underwent an emergency operation were associated with a 6-fold higher risk of receiving prophylactic therapy following surgery.

CONCLUSIONS

The present study demonstrated the existence of a surprisingly low level of overall compliance with the hospital-adapted SAP guidelines. Factors implicated in noncompliance were investigated, and the present results create a starting point to improve the current practice.

Evaluation Intravenous Drip Cephazolin Prophylaxis of Breast Cancer Surgery Site Infection

PURPOSE

The efficacy of antibiotic prophylaxis for the prevention of surgical site infection (SSI) after breast cancer surgery remains uncertain. The authors of a recent Cochrane meta-analysis based on 15 randomized trials were unable to draw a definitive conclusion. The purpose of this study was to determine the effectiveness of prophylactic antibiotics for the prevention of SSI after breast cancer surgery and the risk factors for SSI.

METHODS

Breast cancer patients who underwent mastectomy at the authors' institution were enrolled in this study. All the patients give cephazolin by intravenous drip within 1 hour before surgery. Surgical site infection was defined using Centers for Disease Control criteria. Risk factors were abstracted from the electronic medical record. Pearson χ test, Student t test, and multivariable logistic regression were used for the analysis.

RESULTS

Four hundred fifty-eight patients undergoing mastectomy were enrolled in this study, including 293 with intravenous drip cephazolin and 165 without. Among them, an overall SSI rate of 6.1% was observed; 4.2% of patients without prophylactic antibiotics developed SSI compared with 7.2% with antibiotics (P = 0.210). Factors associated with SSI were hypertension, diabetes, length of stay (d), age, and length of stay. Weight, duration of surgery, No. of drains, surgical procedure, and type of breast disease were not associated with increased SSI rates.

CONCLUSIONS

Surgical site infection rates among patients who did and did not receive cephazolin after mastectomy had no significantly different. What is more, the authors should focus on advanced age, hypertension, diabetes, length of stay, and length of stay to decrease development of postoperative SSI rates.

Appropriateness of Surgical Antibiotic Prophylaxis in Pediatric Patients in Italy

OBJECTIVES

Appropriate use of surgical antibiotic prophylaxis (SAP) reduces intraoperative wound contamination in pediatric surgery, thus minimizing the risk of surgical site infection (SSIs). Conversely, inappropriate use of SAP exposes patients to the risk of antibiotic side effects and contributes to the emergence of antimicrobial resistance. Our aims were to describe SAP administration and to analyze factors associated with nonadherence in pediatric patients.

DESIGN

Descriptive study.

SETTING

Overall, 955 pediatric patients underwent 1,038 surgical procedures.

METHODS

We assessed adherence to SAP international guidelines for surgical procedures performed on children aged <18 years in 2015 in 4 randomly selected hospitals in Calabria (Italy). The clinical records of these patients were retrospectively reviewed.

RESULTS

Appropriate SAP administration or nonadministration pertained to 754 surgical procedures (72.6%). Surgical antibiotic prophylaxis was administered in 88.5% of 358 procedures with an SAP indication. Adherence to guidelines for appropriate drug choice were followed in 5.7% of cases, for route of administration in 76.7% of cases, for timing in 48.6% of cases, for duration in 14.5% of cases, and for dose in 91.5% of cases, and for all components in only 5 cases (1.6%). Among 680 procedures without SAP indication, 35.7% case patients received antibiotics. Inappropriate administration of antibiotics in procedures without SAP indication was associated with surgical specialty wards (P=.008), ordinary admission (P<.001), head and neck surgical procedures (P=.020), clean surgery (P=.017), and surgical duration (P=.010).

CONCLUSIONS

Discrepancies between SAP guidelines and actual practice behavior more frequently indicate excessive use of antibiotics than underuse. Increased awareness of SAP guidelines is required.

Assessment of implementability of an adapted clinical practice guideline for surgical antimicrobial prophylaxis at a tertiary care university hospital

RATIONALE, AIMS AND OBJECTIVES

Surgical site infections are the most common healthcare-associated infections. Appropriate surgical antimicrobial prophylaxis (SAP), which is an integral part of surgical site infection SSI prevention, is one of the major preventable risks to surgical patient safety. Several clinical practice guidelines (CPGs) for SAP have been published. The aim of this study was to adapt a CPG for SAP and to assess its implementability.

METHODS

The methodology was based on two validated tools for CPGs, namely, the ADAPTE and the Guideline Implementability Appraisal (GLIA).

RESULTS

The ADAPTE CPG adaptation process methodology was utilized to produce an adapted CPG for SAP based on the American Society of Health System Pharmacists 2013 CPG. The finalized CPG was then assessed to identify any possible intrinsic barriers for implementation.

CONCLUSIONS

In conclusion, the ADAPTE tool is a practical and successful tool for production of CPGs. The GLIA tool is useful for assessing and preparing the finalized adapted CPG for the transition from the production stage to the implementation stage. GLIA could be added to the ADAPTE process either as a final step or to check the draft of the CPG before finalization.

Cost-Effectiveness Analysis of the Use of a Prophylactic Antibiotic for Patients Undergoing Lower Limb Amputation due to Diabetes or Vascular Illness in Colombia

BACKGROUND

The use of a prophylactic antibiotic in an amputation surgery is a key element for the successful recovery of the patient. We aim to determine, from the perspective of the Colombian health system, the cost-effectiveness of administering a prophylactic antibiotic among patients undergoing lower limb amputation due to diabetes or vascular illness in Colombia.

METHODS

A decision tree was constructed to compare the use and nonuse of a prophylactic antibiotic. The probabilities of transition were obtained from studies identified from a systematic review of the clinical literature. The chosen health outcome was reduction in mortality due to prevention of infection. The costs were measured by expert consensus using the standard case methodology, and the resource valuation was carried out using national-level pricing manuals. Deterministic sensitivity, scenarios, and probabilistic analyses were conducted.

RESULTS

In the base case, the use of a prophylactic antibiotic compared with nonuse was a dominant strategy. This result was consistent when considering different types of medications and when modifying most of the variables in the model. The use of a prophylactic antibiotic ceases to be dominant when the probability of infection is greater than 48%.

CONCLUSIONS

The administration of a prophylactic antibiotic was a dominant strategy, which is a conclusion that holds in most cases examined; therefore, it is unlikely that the uncertainty around the estimation of costs and benefits change the results. We recommend creating policies oriented toward promoting the use of a prophylactic antibiotic during amputation surgery in Colombia.

An Evaluation of Surgical Prophylaxis Procedures in Turkey: A Multi-Center Point Prevalence Study

OBJECTIVE

The purpose of this study was to evaluate compliance with guidelines in surgical prophylaxis (SP) procedures in Turkey.

MATERIALS AND METHODS

A point prevalence study involving 4 university, 5 education and research and 7 public hospitals was performed assessing compliance with guidelines for antibiotic use in SP. Compliance was based on the "Clinical Practice Guidelines for Antimicrobial Surgery (CPGAS) 2013" guideline.

RESULTS

Sixteen centers were included in the study, with 166 operations performed at these being evaluated. Parenteral antibiotic for SP was applied in 161 (96.9%) of these. Type of antibiotic was inappropriate in 66 (40.9%) cases and duration of use in 47 (29.1%). The main antibiotics used inappropriately in SP were ceftriaxone, glycopeptides and aminoglycosides. No significant difference was observed between secondary and tertiary hospitals in terms of inappropriate selection. Duration of prophylaxis was also incompatible with guideline recommendations in approximately half of surgical procedures performed in both secondary and tertiary hospitals, however statistical significance was observed between institutions in favor of tertiary hospitals.

CONCLUSION

Antibiotics are to a considerable extent used in a manner incompatible with guidelines even in tertiary hospitals in Turkey. It must not be forgotten that several pre-, intra- and postoperative factors can be involved in the development of surgical site infections (SSI), and antibiotics are not the only option available for preventing these. A significant improvement can be achieved in prophylaxis with close observation, educational activities, collaboration with the surgical team and increasing compliance with guidelines. All health institutions must establish and apply their own SP consensus accompanied by the guidelines in order to achieve success in SP.

Adherence to Surgical Antibiotic Prophylaxis Guidelines in New South Wales, Australia: Identifying Deficiencies and Regression Analysis of Contributing Factors

BACKGROUND

Surgical antibiotic prophylaxis is frequently reported in the literature to be suboptimal, a finding having both clinical and public health implications. This study aimed to calculate rates and patterns of adherence to guidelines at two sites and identify extrinsic contributing factors.

METHODS

A retrospective analysis was conducted over two 12-mo periods during 2013-2014 at the metropolitan Blacktown Hospital and regional Lismore Base Hospital, New South Wales, Australia. A group of 400 patients undergoing abdominal general surgery was selected via simple random sampling (n = 200 per site). Medical records were reviewed, and prophylactic antibiotic regimens were compared with the Australian guideline, Therapeutic Guidelines: Antibiotic (v. 14) with respect to drug choice, dosage, timing of administration, and duration of administration.

RESULTS

The overall rate of adherence to the guidelines was 16.5% at Blacktown Hospital and 19.5% at Lismore Base Hospital. At each site, prophylaxis was administered to more than 95% of patients and was inappropriately withheld in 4%. Drug choice was the most frequent error type, specifically involving inappropriate omission of metronidazole and use of newer-generation cephalosporins. Errors in the timing of administration also were frequent, with prophylaxis typically occurring excessively early. Logistic regression identified emergency surgery as independently associated with prophylactic errors in both the Blacktown Hospital (p < 0.001) and the Lismore Base Hospital cohorts (p = 0.020).

CONCLUSIONS

Adherence to antibiotic prophylactic guidelines was poor at both the metropolitan and regional sites. Choice of antibiotic and timing of administration were identified as major error types. Consideration should be given to multidisciplinary involvement of anesthetists, implementation of focused interventions with an emphasis on emergency settings, and further research correlating antibiotic use with clinical significance.
