Clinical practice guidelines for the management of adult patients with neurogenic lower urinary tract dysfunction: a systematic review protocol

INTRODUCTION

Neurogenic lower urinary tract dysfunction (NLUTD) both threatens the health of affected patients long-term and also has a significantly negative impact on the patients' quality of life. present, many clinical practice guidelines (CPGs) have been developed for NLUTD patients, but these CPGs may confuse healthcare professionals and patients due to their great difference in terms of scope, quality and content. This review aims to identify the CPGs for NLUTD patients published from 2012 to 2022, assess their quality and then analyse them in an integrated manner.

METHODS AND ANALYSIS

We will systematically search electronic healthcare databases (English databases including PubMed, EMBASE, OVID, Scopus, Web of Science, Cochrane Library, CINAHL, UpToDate, and Best Practice and Chinese databases including China National Knowledge Infrastructure, Wanfang Database, VIP Periodical Resource Integration Service Platform and SinoMed), online CPG repositories and relevant professional association websites to identify eligible CPGs. The CPGs published in English and Chinese with full texts available within the period from January 2012 to March 2022 will be included in this study. The Appraisal of Guidelines for Research and Evaluation (AGREE) II will be used to assess the quality of included CPGs. According to the predesigned data table, the general characteristics of these CPGs, proposed recommendations and their quality of evidence, strength of recommendation and other information will be extracted. Qualitative thematic analysis will be applied to the extracted recommendations. A summary of the proposed recommendations, their quality of evidence, strength of recommendation and other information will eventually be described in a table. This review is expected to identify knowledge gaps in current CPGs and to identify the areas of the proposed recommendations derived from low-level evidence. ETHICS AND DISSEMINATION : This systematic review does not involve the participation of any subjects, and therefore no ethical approval is required. The findings of this review will be published in a peer-reviewed journal and disseminated via conference presentations.

Implementation of Clinical Practice Guidelines for Empirical Antibiotic Therapy of Bacteremia, Urinary Tract Infection, and Pneumonia: A Multi-Center Quasi-Experimental Study

A quasi-experimental study was conducted on the implementation of locally developed clinical practice guidelines (CPGs) for empirical antibiotic (ATB) therapy of common infections (bacteremia, urinary tract infection (UTI), pneumonia) in the hospitals from January 2019 to December 2020. The CPGs were developed using data from patients with these infections at individual hospitals. Relevant CPG data pre- and post-implementation were collected and compared. Of the 1644 patients enrolled in the study, 808 and 836 were in the pre- and post-implementation periods, respectively, and patient outcomes were compared. Significant reductions in the mean durations of intensive care unit stay (3.44 ± 9.08 vs. 2.55 ± 7.89 days; p = 0.035), ventilator use (5.73 ± 12.14 vs. 4.22 ± 10.23 days; p = 0.007), piperacillin/tazobactam administration (0.954 ± 3.159 vs. 0.660 ± 2.217 days, p = 0.029), and cefoperazone/sulbactam administration (0.058 ± 0.737 vs. 0.331 ± 1.803 days, p = 0.0001) occurred. Multivariate analysis demonstrated that CPG-implementation was associated with favorable clinical outcomes (adjusted odds ratio 1.286, 95% confidence interval: 1.004–1.647, p = 0.046). Among patients who provided follow-up cultures (n = 284), favorable microbiological responses were significantly less frequent during the pre-implementation period than the post-implementation period (80.35% vs. 91.89%; p = 0.01). In conclusion, the locally developed CPG implementation is feasible and effective in improving patient outcomes and reducing ATB consumption. Hospital antimicrobial stewardship teams should be able to facilitate CPG development and implementation for antimicrobial therapy for common infections.

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.

Strategies to enhance rational use of antibiotics in hospital: a guideline by the German Society for Infectious Diseases

Introduction

In the time of increasing resistance and paucity of new drug development there is a growing need for strategies to enhance rational use of antibiotics in German and Austrian hospitals. An evidence-based guideline on recommendations for implementation of antibiotic stewardship (ABS) programmes was developed by the German Society for Infectious Diseases in association with the following societies, associations and institutions: German Society of Hospital Pharmacists, German Society for Hygiene and Microbiology, Paul Ehrlich Society for Chemotherapy, The Austrian Association of Hospital Pharmacists, Austrian Society for Infectious Diseases and Tropical Medicine, Austrian Society for Antimicrobial Chemotherapy, Robert Koch Institute.

Materials and methods

A structured literature research was performed in the databases EMBASE, BIOSIS, MEDLINE and The Cochrane Library from January 2006 to November 2010 with an update to April 2012 (MEDLINE and The Cochrane Library). The grading of recommendations in relation to their evidence is according to the AWMF Guidance Manual and Rules for Guideline Development.

Conclusion

The guideline provides the grounds for rational use of antibiotics in hospital to counteract antimicrobial resistance and to improve the quality of care of patients with infections by maximising clinical outcomes while minimising toxicity. Requirements for a successful implementation of ABS programmes as well as core and supplemental ABS strategies are outlined. The German version of the guideline was published by the German Association of the Scientific Medical Societies (AWMF) in December 2013.

Antimicrobial stewardship activities: a survey of Queensland hospitals

OBJECTIVE

In 2011, the Australian Commission on Safety and Quality in Health Care (ACSQHC) recommended that all hospitals in Australia must have an Antimicrobial Stewardship (AMS) program by 2013. Nevertheless, little is known about current AMS activities. This study aimed to determine the AMS activities currently undertaken, and to identify gaps, barriers to implementation and opportunities for improvement in Queensland hospitals.

METHODS

The AMS activities of 26 facilities from 15 hospital and health services in Queensland were surveyed during June 2012 to address strategies for effective AMS: implementing clinical guidelines, formulary restriction, reviewing antimicrobial prescribing, auditing antimicrobial use and selective reporting of susceptibility results.

RESULTS

The response rate was 62%. Nineteen percent had an AMS team (a dedicated multidisciplinary team consisting of a medically trained staff member and a pharmacist). All facilities had access to an electronic version of Therapeutic Guidelines: Antibiotic, with a further 50% developing local guidelines for antimicrobials. One-third of facilities had additional restrictions. Eighty-eight percent had advice for restricted antimicrobials from in-house infectious disease physicians or clinical microbiologists. Antimicrobials were monitored with feedback given to prescribers at point of care by 76% of facilities. Deficiencies reported as barriers to establishing AMS programs included: pharmacy resources, financial support by hospital management, and training and education in antimicrobial use.

CONCLUSIONS

Several areas for improvement were identified: reviewing antimicrobial prescribing with feedback to the prescriber, auditing, and training and education in antimicrobial use. There also appears to be a lack of resources to support AMS programs in some facilities. WHAT IS KNOWN ABOUT THE TOPIC?: The ACSQHC has recommended that all hospitals implement an AMS program by 2013 as a requirement of Standard 3 (Preventing and Controlling Healthcare-Associated Infections) of the National Safety and Quality Health Service Standards. The intent of AMS is to ensure appropriate prescribing of antimicrobials as part of the broader systems within a health service organisation to prevent and manage healthcare-associated infections, and improve patient safety and quality of care. This criterion also aligns closely with Standard 4: Medication Safety. Despite this recommendation, little is known about what AMS activities are undertaken in these facilities and what additional resources would be required in order to meet these national standards. WHAT DOES THE PAPER ADD?: This is the first survey that has been conducted of public hospital and health services in Queensland, a large decentralised state in Australia. This paper describes what AMS activities are currently being undertaken, identifies practice gaps, barriers to implementation and opportunities for improvement in Queensland hospitals. WHAT ARE THE IMPLICATIONS FOR PRACTITIONERS?: Several areas for improvement such as reviewing antimicrobial prescribing with feedback to the prescriber, auditing, and training and education in antimicrobial use have been identified. In addition, there appears to be a lack of resources to support AMS programs in some facilities.

Development of Standardized Clinical Assessment and Management Plans (SCAMPs) in Plastic and Reconstructive Surgery

Background:

With rising cost of healthcare, there is an urgent need for developing effective and economical streamlined care. In clinical situations with limited data or conflicting evidence-based data, there is significant institutional and individual practice variation. Quality improvement with the use of Standardized Clinical Assessment and Management Plans (SCAMPs) might be beneficial in such scenarios. The SCAMPs method has never before been reported to be utilized in plastic surgery.

Methods:

The topic of immediate breast reconstruction was identified as a possible SCAMPs project. The initial stages of SCAMPs development, including planning and implementation, were entered. The SCAMP Champion, along with the SCAMPs support team, developed targeted data statements. The SCAMP was then written and a decision-tree algorithm was built. Buy-in was obtained from the Division of Plastic Surgery and a SCAMPs data form was generated to collect data.

Results:

Decisions pertaining to “immediate implant-based breast reconstruction” were approved as an acceptable topic for SCAMPs development. Nine targeted data statements were made based on the clinical decision points within the SCAMP. The SCAMP algorithm, and the SDF, required multiple revisions. Ultimately, the SCAMP was effectively implemented with multiple iterations in data collection.

Conclusions:

Full execution of the SCAMP may allow better-defined selection criteria for this complex patient population. Deviations from the SCAMP may allow for improvement of the SCAMP and facilitate consensus within the Division. Iterative and adaptive quality improvement utilizing SCAMPs creates an opportunity to reduce cost by improving knowledge about best practice.

A qualitative study of the variable effects of audit and feedback in the ICU

BACKGROUND

Audit and feedback is integral to performance improvement and behaviour change in the intensive care unit (ICU). However, there remain large gaps in our understanding of the social experience of audit and feedback and the mechanisms whereby it can be optimised as a quality improvement strategy in the ICU setting.

METHODS

We conducted a modified grounded theory qualitative study. Seventy-two clinicians from five academic and five community ICUs in Ontario, Canada, were interviewed. Team members reviewed interview transcripts independently. Data analysis used constant comparative methods.

RESULTS

Clinicians interviewed experienced audit and feedback as fragmented and variable in its effectiveness. Moreover, clinicians felt disconnected from the process. The audit process was perceived as being insufficiently transparent. Feedback was often untimely, incomplete and not actionable. Specific groups such as respiratory therapists and night-shift clinicians felt marginalised. Suggestions for improvement included improving information sharing about the rationale for change and the audit process, tools and metrics; implementing peer-to-peer quality discussions to avoid a top-down approach (eg, incorporating feedback into discussions at daily rounds); providing effective feedback which contains specific, transparent and actionable information; delivering timely feedback (ie, balancing feedback proximate to events with trends over time) and increasing engagement by senior management.

CONCLUSIONS

ICU clinicians experience audit and feedback as fragmented communication with feedback being especially problematic. Attention to improving communication, integration of the process into daily clinical activities and making feedback timely, specific and actionable may increase the effectiveness of audit and feedback to affect desired change.

Antibiotic stewardship programmes in intensive care units: Why, how, and where are they leading us

Antibiotic usage and increasing antimicrobial resistance (AMR) mount significant challenges to patient safety and management of the critically ill on intensive care units (ICU). Antibiotic stewardship programmes (ASPs) aim to optimise appropriate antibiotic treatment whilst minimising antibiotic resistance. Different models of ASP in intensive care setting, include “standard” control of antibiotic prescribing such as “de-escalation strategies”through to interventional approaches utilising biomarker-guided antibiotic prescribing. A systematic review of outcomes related studies for ASPs in an ICU setting was conducted. Forty three studies were identified from MEDLINE between 1996 and 2014. Of 34 non-protocolised studies, [1 randomised control trial (RCT), 22 observational and 11 case series], 29 (85%) were positive with respect to one or more outcome: These were the key outcome of reduced antibiotic use, or ICU length of stay, antibiotic resistance, or prescribing cost burden. Limitations of non-standard antibiotic initiation triggers, patient and antibiotic selection bias or baseline demographic variance were identified. All 9 protocolised studies were RCTs, of which 8 were procalcitonin (PCT) guided antibiotic stop/start interventions. Five studies addressed antibiotic escalation, 3 de-escalation and 1 addressed both. Six studies reported positive outcomes for reduced antibiotic use, ICU length of stay or antibiotic resistance. PCT based ASPs are effective as antibiotic-stop (de-escalation) triggers, but not as an escalation trigger alone. PCT has also been effective in reducing antibiotic usage without worsening morbidity or mortality in ventilator associated pulmonary infection. No study has demonstrated survival benefit of ASP. Ongoing challenges to infectious disease management, reported by the World Health Organisation global report 2014, are high AMR to newer antibiotics, and regional knowledge gaps in AMR surveillance. Improved AMR surveillance data, identifying core aspects of successful ASPs that are transferable, and further well-conducted trials will be necessary if ASPs are to be an effective platform for delivering desired patient outcomes and safety through best antibiotic policy.

How to assist clinicians in improving antimicrobial prescribing: tools and interventions provided by stewardship programs

In the last decade, there has been an exponential increase in the microorganisms resistant to antimicrobials and a significant increase in the cost of these types of drugs. This phenomenon has increased interest in the development of interventions for counseling on and control of the use of antimicrobials, referred to as stewardship programs. In this article we review, from various points of view, the tools that have been developed with this purpose. First, we highlight the value of locally adapted guidelines and clinical pathways as an essential part of the operational process. Then we emphasize the importance of the relationship between microbiologists and clinicians for the accurate transmission of the information provided by blood cultures to make the most appropriate choice of antimicrobial for the patient's treatment. We also review the computerized tools that have facilitated the correct use of antimicrobials according to the controls established by the departments of pharmacy. Based on the previous tools, some programs based on "bedside recommendations" provided by multidisciplinary teams have been developed for optimizing the rational use of antimicrobials (PROA programs). Finally, we comment on the peculiarities of the programs targeting antifungals that have been developed in recent years.

Knowledge translation interventions for critically ill patients: a systematic review*

OBJECTIVE

We systematically reviewed ICU-based knowledge translation studies to assess the impact of knowledge translation interventions on processes and outcomes of care.

DATA SOURCES

We searched electronic databases (to July, 2010) without language restrictions and hand-searched reference lists of relevant studies and reviews.

STUDY SELECTION

Two reviewers independently identified randomized controlled trials and observational studies comparing any ICU-based knowledge translation intervention (e.g., protocols, guidelines, and audit and feedback) to management without a knowledge translation intervention. We focused on clinical topics that were addressed in greater than or equal to five studies.

DATA EXTRACTION

Pairs of reviewers abstracted data on the clinical topic, knowledge translation intervention(s), process of care measures, and patient outcomes. For each individual or combination of knowledge translation intervention(s) addressed in greater than or equal to three studies, we summarized each study using median risk ratio for dichotomous and standardized mean difference for continuous process measures. We used random-effects models. Anticipating a small number of randomized controlled trials, our primary meta-analyses included randomized controlled trials and observational studies. In separate sensitivity analyses, we excluded randomized controlled trials and collapsed protocols, guidelines, and bundles into one category of intervention. We conducted meta-analyses for clinical outcomes (ICU and hospital mortality, ventilator-associated pneumonia, duration of mechanical ventilation, and ICU length of stay) related to interventions that were associated with improvements in processes of care.

DATA SYNTHESIS

From 11,742 publications, we included 119 investigations (seven randomized controlled trials, 112 observational studies) on nine clinical topics. Interventions that included protocols with or without education improved continuous process measures (seven observational studies and one randomized controlled trial; standardized mean difference [95% CI]: 0.26 [0.1, 0.42]; p = 0.001 and four observational studies and one randomized controlled trial; 0.83 [0.37, 1.29]; p = 0.0004, respectively). Heterogeneity among studies within topics ranged from low to extreme. The exclusion of randomized controlled trials did not change our results. Single-intervention and lower-quality studies had higher standardized mean differences compared to multiple-intervention and higher-quality studies (p = 0.013 and 0.016, respectively). There were no associated improvements in clinical outcomes.

CONCLUSIONS

Knowledge translation interventions in the ICU that include protocols with or without education are associated with the greatest improvements in processes of critical care.

KPC - 3 Klebsiella pneumoniae ST258 clone infection in postoperative abdominal surgery patients in an intensive care setting: analysis of a case series of 30 patients

BACKGROUND

Abdominal surgery carries significant morbidity and mortality, which is in turn associated with an enormous use of healthcare resources. We describe the clinical course of 30 Intensive Care Unit (ICU) patients who underwent abdominal surgery and showed severe infections caused by Klebsiella pneumoniae sequence type (ST) 258 producing K. pneumoniae carbapenemase (KPC-Kp). The aim was to evaluate risk factors for mortality and the impact of a combination therapy of colistin plus recommended regimen or higher dosage of tigecycline.

METHODS

A prospective assessment of severe monomicrobial KPC-Kp infections occurring after open abdominal surgery carried out from August 2011 to August 2012 in the same hospital by different surgical teams is presented. Clinical and surgical characteristics, microbiological and surveillance data, factors associated with mortality and treatment regimens were analyzed. A combination regimen of colistin with tigecycline was used. A high dose of tigecycline was administered according to intra-abdominal abscess severity and MICs for tigecycline.

RESULTS

The mean age of the patients was 56.6 ± 15 and their APACHE score on admission averaged 22.72. Twenty out of 30 patients came from the surgical emergency unit. Fifteen patients showed intra-abdominal abscess, eight anastomotic leakage, four surgical site infection (SSI) and three peritonitis. The overall crude ICU mortality rate was 40% (12 out of 30 patients). Twelve of the 30 patients were started on a combination treatment of high-dose tigecycline and intravenous colistin. A significantly lower mortality rate was observed among those patients compared to patients treated with approved dose of tigecycline plus colistin. No adverse events were reported with high doses of tigecycline.

CONCLUSIONS

Critically-ill surgical patients are prone to severe post-surgical infectious complications caused by KPC-Kp. Timely microbiological diagnosis and optimizing antibiotic dosing regimens are essential to prevent worse outcomes. Further studies and well-controlled clinical trials are needed to define the optimal treatment of infections by KPC-Kp and, more generally, carbapenem-resistant bacteria.

Antibiotic stewardship: overcoming implementation barriers

PURPOSE OF REVIEW

Antimicrobial stewardship is now recognized as a formal strategy for curbing the upward trend in antibiotic resistance. Literature on antimicrobial stewardship has focused on areas of strategic importance and operational delivery. A number of barriers have been recognized in the implementation of successful programs. These include lack of physician participation, lack of diagnostic facility, absence of formal mechanism of data collection, variation between countries, and lack of cooperative strategies. In this review, we suggest strategies to overcome these barriers.

RECENT FINDINGS

In the last few years, it has been recognized that an executive program is necessary for successful implementation of strategies to control the growing antibiotic resistance. Efforts have been made at higher levels of government through organizations such as the European Centre for Disease Prevention and Control. The need for community healthcare involvement has also been recognized. At a local level, strategies to promote cooperation between various committees (e.g. infection control and antimicrobial management teams) have been proposed and adopting antibiotic care bundles as part of patient safety and healthcare is being explored.

SUMMARY

We suggest that executive level planning, local cooperation, sustained education, emphasis on de-escalation, and use of care bundles could stem the tide of growing resistance.

Faculty perceptions of interprofessional education

Nurses and other health professionals are required to demonstrate broad levels of expertise and service to ensure quality patient-centred health care. Interprofessional practice aligned with interprofessional education (IPE) has been promoted as a vehicle to promote broad levels of expertise. However, challenges remain for universities and other higher education institutions to successfully provide IPE opportunities for students. This paper presents perceptions of academic staff towards IPE from one Australian multi-campus health faculty. Perceptions were collected using interviews and two workshops. Findings are themed under the categories of faculty barriers, industry challenges and future opportunities. The perceptions of one health faculty regarding the fundamental factors required for IPE success were executive leadership of IPE, a supportive funding framework and an IPE based curricula. Nursing education can play a key role in embracing and leading future IPE approaches given that nurses are the numerically dominant health professional group and work collaboratively with other professionals to deliver patient-centred care.

The value of audit and feedback reports in improving nutrition therapy in the intensive care unit: a multicenter observational study

BACKGROUND

The objective of this study was to determine whether auditing practice and providing feedback in the form of benchmarked site reports is an effective strategy to improve adherence to nutrition guidelines.

METHODS

The authors conducted a multicenter observational study in Canadian intensive care units (ICUs). In January 2007, an audit of daily nutrition information was collected (type and amount of nutrition received and strategies to improve nutrition delivery). Each ICU was e-mailed individualized benchmarked performance reports documenting their performance compared with the Canadian Critical Care Nutrition guidelines and in relation to the other ICUs. Nutrition practice was reaudited in May 2008 to evaluate changes in practice.

RESULTS

Twenty-six ICUs in Canada participated, with 473 and 486 patients accrued in 2007 and 2008, respectively. The authors observed a significant increase in enteral nutrition (EN) adequacy (from 45.1% to 51.9% for calories, and from 44.8% to 51.5% for protein) and an increase in the percentage of patients receiving EN without parenteral nutrition (from 71.9% to 81.3%). They also observed trends toward improvements in the percentage of patients who had EN started within 48 hours (from 60.3% to 66.8%). There were no significant differences in the use of motility agents or small bowel feeding in patients who had high gastric residual volumes.

CONCLUSION

Audit and feedback reports are associated with improvement in some nutrition practices in many ICUs; however, the magnitude of these effects is quite modest. More research is needed to determine the optimal methods of using audit and feedback to improve quality of nutrition care.

Impact of antimicrobial stewardship in critical care: a systematic review

OBJECTIVES

To evaluate the current state of evidence for antimicrobial stewardship interventions in the critical care unit.

METHODS

We performed a systematic search of OVID MEDLINE, Embase and Cochrane electronic databases from 1996-2010. Studies were included if they involved any experimental intervention to improve antimicrobial utilization in the critical care setting.

RESULTS

Thirty-eight studies met the inclusion criteria, of which 24 met our quality inclusion criteria. The quality of research was poor, with only 3 randomized controlled trials, 3 interrupted time series and 18 (75%) uncontrolled before-and-after studies. We identified six intervention types: studies of antibiotic restriction or pre-approval (six studies); formal infectious diseases physician consultation (five); implementation of guidelines or protocols for de-escalation (two); guidelines for antibiotic prophylaxis or treatment in intensive care (two); formal reassessment of antibiotics on a pre-specified day of therapy (three); and implementation of computer-assisted decision support (six). Stewardship interventions were associated with reductions in antimicrobial utilization (11%-38% defined daily doses/1000 patient-days), lower total antimicrobial costs (US$ 5-10/patient-day), shorter average duration of antibiotic therapy, less inappropriate use and fewer antibiotic adverse events. Stewardship interventions beyond 6 months were associated with reductions in antimicrobial resistance rates, although this differed by drug-pathogen combination. Antibiotic stewardship was not associated with increases in nosocomial infection rates, length of stay or mortality.

CONCLUSIONS

More rigorous research is needed, but available evidence suggests that antimicrobial stewardship is associated with improved antimicrobial utilization in the intensive care unit, with corresponding improvements in antimicrobial resistance and adverse events, and without compromise of short-term clinical outcomes.

[Antibiotics in elderly patients: Impact of clinical practice evaluation]

OBJECTIVE

Improving the use of antimicrobial drugs is a national objective. To this end an evaluation of clinical practice was implemented on prescribed antibiotics in elderly patients, in the Besançon Teaching Hospital.

DESIGN

In 2005, a clinical audit compared the adequacy of antibiotic prescriptions to national guidelines in 37 patients. An improvement plan was implemented, including the drafting of local guidelines (adapted national guidelines) "Antibiotic prescription in elderly patients" by a multidisciplinary team. The Antibiotics Committee approved it. A retrospective study compared antibiotic prescription of 62 patients to these guidelines. The methodology was based on Gyssen's algorithm. The assessment criteria were: relevance of the indication, absence of a better alternative, respect of recommended dose, duration, and timing.

RESULTS

The rate of overall conformity was 26% in 2005, 57% in 2007. Antibiotic choice was adequate in 61% of cases in 2005, 78% in 2007. In 63% of cases, a more efficient alternative was advised in 2005, 10% of cases in 2007. Treatment duration, dose, and timing were adequate in 54 - 92 - 96% in 2005 respectively and 86 - 92 - 100% of cases in 2007. Ciprofloxacin was prescribed in first line for 42% of urinary infections in 2005, 0% in 2007.

CONCLUSIONS

This approach improved antibiotic prescriptions because of better guideline observance by physicians. The main improvement concerned fluoroquinolones. It should be continued to confirm antibiotic good use and protect our hospital bacterial ecology.

Resource utilization after introduction of a standardized clinical assessment and management plan

INTRODUCTION

A Standardized Clinical Assessment and Management Plan (SCAMP) is a novel quality improvement initiative that standardizes the assessment and management of all patients who carry a predefined diagnosis. Based on periodic review of systemically collected data the SCAMP is designed to be modified to improve its own algorithm. One of the objectives of a SCAMP is to identify and reduce resource utilization and patient care costs.

METHODS

We retrospectively reviewed resource utilization in the first 93 arterial switch operation (ASO) SCAMP patients and 186 age-matched control ASO patients. We compared diagnostic and laboratory testing obtained at the initial SCAMP clinic visit and control patient visits. To evaluate the effect of the SCAMP over time, the number of clinic visits per patient year and echocardiograms per patient year in historical control ASO patients were compared to the projected rates for ASO SCAMP participants.

RESULTS

Cardiac magnetic resonance imaging (MRI), stress echocardiogram, and lipid profile utilization were higher in the initial SCAMP clinic visit group than in age-matched control patients. Total echocardiogram and lung scan usage were similar. Chest X-ray and exercise stress testing were obtained less in SCAMP patients. ASO SCAMP patients are projected to have 0.5 clinic visits and 0.5 echocardiograms per year. Historical control patients had more clinic visits (1.2 vs. 0.5 visits/patient year, P<.01) and a higher echocardiogram rate (0.92 vs. 0.5 echocardiograms/patient year, P<.01)

CONCLUSION

Implementation of a SCAMP may initially lead to increased resource utilization, but over time resource utilization is projected to decrease.

Managing antimicrobial resistance in intensive care units

The challenges in managing patients with infection in the intensive care unit are increased in an era where there are dwindling antimicrobial choices for multidrug-resistant pathogens. Clinicians in the intensive care unit must balance between choosing appropriate antimicrobial treatment for patients with suspected infection and utilizing antimicrobials in a judicious fashion. Improving antimicrobial utilization is a critical component to reducing antimicrobial resistance. Although providing effective antimicrobial therapy and improving antimicrobial utilization may seem to be competing goals, there are effective strategies to accomplish both. Antimicrobial stewardship programs provide an organized way to implement these strategies and can enhance the intensive care unit physician's success in improving patient outcomes and combating antimicrobial resistance in the intensive care unit.

Controlling antimicrobial resistance in the hospital

Most evidence-based methods to control the spread of antimicrobial resistance have been developed and applied to the hospital setting. Strategies to control the emergence and spread of antimicrobial resistance in hospitals can be categorized as either infection control or antibiotic stewardship strategies. Infection control is the discipline focused on preventing the spread of infections within the health care setting; antibiotic stewardship can help minimize the emergence of multidrug-resistant organisms by promoting prudent use of antibiotics. This article describes different infection control and antibiotic management strategies that can be used to control antimicrobial resistance in hospital settings.

Nationwide implementation of antibiotic management teams in Belgian hospitals: a self-reporting survey

OBJECTIVES

Antibiotic management teams (AMTs) have been advocated to optimize the use of antimicrobials in hospitals. Since 2002, the Belgian Antibiotic Policy Coordination Committee (BAPCOC) has supported the development of AMTs in Belgian hospitals with policy guidance and federal funding for antibiotic managers. We performed a national, self-reporting survey to assess the level of AMT activities in 2007.

METHODS

A structured questionnaire survey was performed on the composition, organization and service activities of the AMT in all acute care and larger chronic care hospitals in the country in 2007. Descriptive statistics were stratified by duration of AMT funding.

RESULTS

Completed questionnaires were provided by 112 of 116 hospitals (response rate, 96.6%). Mutidisciplinary AMTs varied in size (mean 10, range 2-28 members). Antibiotic stewardship tools used by AMTs included: hospital antibiotic formulary (96.3% of hospitals); practice guidelines for antibiotic therapy and surgical prophylaxis (91.6% and 96.3%, respectively); list of 'restricted' antimicrobial agents (75.9%); concurrent review of antibiotic therapies (64.2%); de-escalation of therapy after a few days (63.9%); sequential intravenous/oral therapy for antibiotics with equivalent bioavailability (78.7%); dedicated antimicrobial order forms (36.1%); automatic stop of delivery (43.5%); analysis of antibiotic consumption data (96.2%); and analysis of microbial resistance data (89.8%).

CONCLUSIONS

These data demonstrate a well-developed structure of AMTs in Belgian hospitals and the broad range of services provided. Technical and financial support by healthcare authorities was key to the extensive implementation of antimicrobial stewardship programmes across the national hospital care system.

Clinical guidelines and off-license recombinant activated factor VII: content, use, and association with patient outcomes

BACKGROUND

Recombinant activated factor VII (rFVIIa) is increasingly being used off-license for treating critical bleeding. Guidelines may therefore be useful for improving processes and outcomes. Little is known regarding guidelines for off-license rFVIIa or their association with patient outcomes.

OBJECTIVES

To investigate the availability of hospital guidelines for off-license rFVIIa use and the association between these guidelines and mortality.

METHODS

Data were extracted from the Haemostasis Registry, which collects all cases of off-license rFVIIa use in participating institutions in Australia and New Zealand. Contributing hospitals were requested to supply a copy of the institutional guideline relating to off-license rFVIIa administration. The characteristics of patients treated in accordance with all elements of the guidelines were compared with those of patients for who one or more guideline elements had been violated. The relationship between guideline-directed treatment and 28-day mortality was investigated using stepwise logistic regression.

RESULTS

Two thousand five hundred and fifty-one patients in 75 hospitals were available for analysis. Of these hospitals, 58 provided a guideline for analysis. Patients complying with all guideline elements (n = 530) did not differ from patients receiving care that violated guidelines (n = 1035) regarding age, size of dose, or gender. Guideline-directed treatment was not found to have an association with 28-day mortality following logistic regression.

CONCLUSIONS

Few patients are treated in accordance with the criteria of rFVIIa guidelines, despite their availability in the majority of hospitals. Moreover, 28-day mortality does not appear to be associated with the use of guidelines in this patient group. Refinement of guidelines relating to the off-license use of rFVIIa is therefore required.

Developing guidelines and maintaining quality in antenatal care

Clinical practice guidelines are mandated by American College of Nurse-Midwives Standards for the Practice of Midwifery. Guidelines should be evidence-based and pertinent to the population served. Guidelines assist midwifery practices in the evaluation and maintenance of quality care. The development of clinical practice guidelines should be rigorous and scientific. There are several sources available to midwives to aid in the development of practice guidelines.

Antibiotic management of sepsis: current concepts

BACKGROUND

The development of guidelines for sepsis management has improved disease survival and reduced treatment costs. Adequate antibiotic therapy is the cornerstone of sepsis treatment. Specific rules should be established in every institution according to its profiles.

OBJECTIVES

To review the current knowledge about the best drugs to be used as empiric treatment for sepsis based on their clinical efficacy and costs.

METHODS

Medline 1950 - 2008 was searched using the following terms: sepsis, organ failure, system failure, SIRS, septic shock, antibiotic, pneumonia, urinary tract infection, urosepsis, catheter-related infection, bloodstream, abdominal infection, and surgical wound.

RESULTS/CONCLUSION

For most septic shock patients, monotherapy is adequate and treatment should be initiated in the first hour after first sepsis-induced organ dysfunction. The drug of choice varies in different situations and choosing the right antibiotic enables better survival, fewer complications and shorter stays in intensive care.

Optimization of antibiotic use in hospitals--antimicrobial stewardship and the EU project ABS international

BACKGROUND

The problem of antimicrobial resistance requires common strategies at the European level.

METHODS

We report on an EU initiative fostering antibiotic (AB) stewardship (ABS) in hospitals.

RESULTS

The project 'ABS International: implementing antibiotic strategies for appropriate use of antibiotics in hospitals in member states of the EU' started in September 2006 in Austria, Belgium, the Czech Republic, Germany, Hungary, Italy, Poland, Slovenia and Slovakia. A training program for national ABS trainers was prepared and standard templates for ABS tools (AB list, guidelines for AB treatment and surgical prophylaxis, and AB-related organization) and valid process measures as well as quality indicators for AB use were developed. Specific ABS tools are being implemented in up to five health care facilities per country.

CONCLUSION

ABS International is the first EU-funded initiative focusing on the implementation of structural measures in hospitals to promote the prudent use of ABs.

Adherence to Standard Operating Procedures is Crucial for Intensive Care Unit Survival of Elderly Patients

Elderly patients account for 42–52% of intensive care unit (ICU) admissions and for almost 60% of all ICU days in the USA and up to 50% receive inappropriate antibiotic treatment. The aim of this study was to evaluate whether adherence to Standard Operating Procedures (SOPs) reduced ICU mortality in an elderly population. The study included consecutive patients ( n = 228) aged ≤ 60 years with an ICU stay of > 72 h. SOPs were based on evidence-based medicine guidelines for diagnosis and treatment of infections, and on local resistance rates. According to preset indicators of quality management standards and assessment of different degrees of adherence, an implementation rate > 70% was considered adherent (high adherence group [HAG]) and ≤ 70% was considered non-adherent (low adherence group [LAG]). Patients in the HAG ( n = 137) had significantly reduced mortality compared with LAG patients ( n = 91): 5.8% versus 19.8%, respectively. It was concluded that adherence to SOPs based on evidence-based medicine that consider local resistance rates for antibiotic treatment in elderly ICU patients is associated with a lower mortality rate.

Impact of the implementation of a therapeutic guideline on the treatment of nosocomial pneumonia acquired in the intensive care unit of a university hospital

OBJECTIVE

To evaluate the impact that the implementation of therapeutic guidelines has on the empirical treatment of nosocomial pneumonia.

METHODS

A clinical trial, using historical controls and involving current ICU patients who had acquired nosocomial pneumonia, was carried out from June of 2002 to June of 2003. All were treated according to therapeutic guidelines developed by the Commission for Nosocomial Infection Control of the institution (group with intervention). As controls, the medical charts of the patients who acquired nosocomial pneumonia between June of 2000 and June of 2001 (group without intervention) were analyzed. Mortality and mean treatment period, as well as the length of hospital and ICU stays, were determined for the patients who acquired nosocomial pneumonia.

RESULTS

Mortality associated with pneumonia was lower in the group treated according to the therapeutic guidelines (26 vs. 53.6%; p = 0.00). As for overall mortality, there was no statistically significant difference between the two periods (51 vs. 57.9%; p = 0.37). There was also no difference in the type of microorganisms isolated, treatment period, length of hospital stay or length of ICU stay.

CONCLUSION

The implementation of therapeutic guidelines for the treatment of nosocomial pneumonia acquired in the ICU can be efficacious in decreasing mortality rates.

Healthcare-associated infection in pediatric patients on extracorporeal life support: The role of multidisciplinary surveillance

OBJECTIVE

To describe the use of a multidisciplinary approach to sepsis surveillance and evaluate impact on outcome.

DESIGN

Prospective clinical study or clinical audit cycle.

SETTING

Tertiary pediatric extracorporeal membrane oxygenation (ECMO) center.

PATIENTS

Patients were 215 children supported with ECMO January 1999 to December 2004.

INTERVENTIONS

A multidisciplinary team met monthly to evaluate cases of bloodstream infection and mediastinitis, review trends, and update unit policies. Changes in practice were made at the end of 2001 in order to address a perceived high rate of sepsis: a) reeducation; b) introduction of electively preprimed ECMO circuits; and c) preference for neck rather than chest cannulation in cardiac patients. Prophylactic antibiotics were used from preprocedure for 24 hrs only throughout the study.

MEASUREMENTS AND MAIN RESULTS

Over the entire study period, 39 children had 47 septic episodes, with a rate of 24.9 per 1000 ECMO days. Multiple logistic regression analyses indicated that infection was associated with duration of ECMO support (odds ratio 1.24; 95% confidence interval 1.15, 1.35 per day) and case type: Closed vs. open chest was protective in cardiac patients (odds ratio 0.08; 95% confidence interval 0.01, 0.50). Infection increased the odds of death by 2.01 (95% confidence interval 1.00, 4.05), but this effect was less important than case type and ECMO days. After policy changes were implemented, there was a reduction in sepsis from 29.3 to 20.1 episodes per 1000 ECMO days. There was reduced sepsis in respiratory patients: neonates from 28.0 to 6.6 and pediatric patients from 42.4 to 16.9 episodes per 1000 ECMO days. Despite policy changes, sepsis remained a problem in cardiac patients with open sternum: 65.1 per 1000 ECMO days.

CONCLUSIONS

ECMO support is a high-risk setup for nosocomial infection, in particular for cardiac patients with open sternum for whom antibiotic prophylaxis is justified. Multidisciplinary surveillance offers an excellent approach for quality improvement in this challenging field.

Infections following major heart surgery in European intensive care units: there is room for improvement (ESGNI 007 Study)

Patients undergoing major heart surgery (MHS) may be at increased risk for nosocomial infections. To assess the incidence and type of infections in MHS patients in European intensive care units (ICUs) and their quality of care, a questionnaire was sent to a selection of MHS ICUs in Europe. Seventeen hospitals from seven European countries participated. Overall, 53% of the ICUs received patients only for MHS and the other 47% were mixed. During the study period, 11 915 patients underwent MHS and 1181 (9.9%) developed one or more nosocomial infections. Ventilator-associated pneumonia (VAP) was the most common infection [median 3.8%; interquartile range (IQR) 1.8-4.9], followed by surgical wound infection (median 1.6%; IQR 0.8-2.3), catheter-related bloodstream infection (median 1.3%; IQR 0.8-2.1), mediastinitis (median 1.1%; IQR 0.4-1.6), urinary tract infection (median 0.6; IQR 0.4-1.4) and nosocomial endocarditis (median 0.2%; IQR 0.0-0.9). Median mortality was 4.7% (IQR 2.7-8.4) and median infection-related mortality was 1% (IQR 0.5-2.7). Regarding VAP, 18% of the ICUs did not routinely pursue a diagnosis. Microbiological information was quantitative in 35% of cases and exclusively qualitative in 65% of cases. An infectious disease specialist was regularly involved in VAP management in only 35% of the ICUs, and the therapeutic approach to VAP involved de-escalation in 59% of the ICUs. MHS ICUs in Europe still have a high rate of postoperative infections. Well-recognized routine practices for the diagnosis and treatment of VAP are not implemented regularly in many European institutions.

Improving the ICU: part 2

ICUs are a vital but troubled component of modern health-care systems. Improving ICU performance requires that we shift from a paradigm that concentrates on individual performance, to a systems-oriented approach that emphasizes the need to assess and improve the ICU systems and processes that hinder the ability of individuals to perform their jobs well. This second part of a two-part treatise establishes a practical framework for performance improvement and examines specific strategies to improve ICU performance, including the use of information systems.

Judicious Use of Antimicrobials in the Critical Care Setting

This article reviews the judicious use of antibiotics in an intensive care setting. Risk factors for both infection and antimicrobial resistance are discussed. Various methods hospitals can apply to promote the optimal use of antibiotics also are reviewed. These methods include empiric therapy, antibiotic cycling, treatment guidelines and protocols, and antibiotic susceptibility monitoring.

A systematic audit of economic evidence linking nosocomial infections and infection control interventions: 1990-2000

BACKGROUND

Nosocomial infections (NIs) are a serious patient safety issue. Infection control personnel are responsible for implementing interventions to reduce this risk. The purpose of this systematic review was to audit the published economic evidence of the attributable cost of NIs and interventions conducted by infection control professionals and to evaluate the methods used. Economic evaluation methodology and recommendations for standardization are reviewed.

METHODS

A search of MEDLINE and HealthSTAR with medical subject headings or text words "nosocomial infections," "infection control," or "hospital acquired infections" cross-referenced with "costs," "cost analysis," "economics," or "cost-effectiveness analysis" was conducted. Published review articles were also searched. Inclusion criteria included articles published between 1990 and 2000 that contained an abstract and original cost estimate and were written in English. Results were standardized into a common currency.

RESULTS

Fifty-five studies were eligible. Approximately one quarter examined NIs in intensive care patients (n = 13). Most studies were conducted from the hospital perspective (n = 48). The costs attributable to bloodstream (mean = $38,703) and methicillin-resistant Staphylococcus aureus infections (mean = $35,367) were the largest.

CONCLUSIONS

Increased standardization and rigor are needed. Clinicians should partner with economists and policy analysts to expand and improve the economic evidence available to reduce hospital complications such as NI and other adverse patient/staff outcomes.

Multicentre evaluation of prescribing concurrence with anti-infective guidelines: epidemiological assessment of indicators

PURPOSE

To assess indicators for anti-infective prescribing not concurrent with regional pharmacotherapeutic treatment guidelines (PTGs) on infectious diseases.

METHODS

A retrospective explorative cohort study based on hospital-wide anti-infective prescription data of a 2-month cross-sectional period (n = 1037). Risk rates (absolute risks: AR), risk rate ratios (relative risks: RR) and odds ratios (OR) with 95% confidence intervals (95%CI) were estimated for patient, disease, drug, and prescriber variables considered to be potential indicators. Univariable and multivariable logistic regression analyses were performed.

FINDINGS

Non-concurrence existed of non-indicated prescribing of (particular) anti-infectives (24.3%) and prescribing of non-first choice anti-infectives (55.2%). Non-concurrent durations of treatment and dosing issues accounted for 17.2% and 16.2% respectively. Non-concurrence was associated with empirical therapy, with certain diagnoses, such as skin and soft tissue, urinary, and osteoarthrological infections, and with prescriptions involving topical dosage forms, cephalosporins, macrolides and lincosamides, and quinolones. There was also an association with certain hospitals and with prescribing by geriatricians, surgeons, pulmonologists, and urologists and, in general, junior clinicians in training.

CONCLUSIONS

Other hospitals could use our epidemiological framework to identify their own indicators for non-concurrent prescribing. Our findings suggest tailor-made enforcement of PTG adherence for certain prescribers while conversely, adaptation of the PTGs will be required for some infectious diseases.
