Objectives: To assess the internal and external validity of a cluster randomized controlled trial (cRCT) evaluating a decision tool with supportive interventions for the empirical treatment of urinary tract infections (UTIs) in nursing homes (NHs), and to identify facilitators and barriers in implementing this antibiotic stewardship intervention., Design: Mixed-methods process evaluation study., Setting and Participants: Physicians, nursing staff, client council members, and residents of Dutch NHs., Methods: We used cRCT data of the ANNA study (Antibiotic Prescribing and Non-prescribing in Nursing Home Residents With Signs and Symptoms Ascribed to Urinary Tract Infection). In addition, we sent out an online evaluation questionnaire, conducted semistructured interviews with physicians and nursing staff, and consulted client council members., Results: Internal validity was lowered: control group physicians participated in several non-study-related activities regarding UTI. External validity was good: almost all intervention components had a high fidelity (52%-74%) and were perceived as relevant (physicians: 7.2-8.6 of 10, nursing staff: 6.5-8.5 of 10) and feasible (physicians: 7.5 of 10, nursing staff 6.4 of 10), with feasibility for residents with dementia and urine incontinence needing attention. The most common reason for deviating from the advice generated by the decision tool was an unclear illness presentation. Identified facilitators to implementation were confidence in the intervention, repeated intervention encounter, and having "champions" in the NH. Barriers were limited involvement of nursing staff, unstable nursing teams, residents' and representatives' belief that antibiotics should be prescribed, and a low antibiotic prescribing threshold within the NH culture., Conclusions and Implications: Lowered internal validity may have reduced the study effect. Attention should be paid to the feasibility of the intervention in residents with dementia and urinary incontinence. Improvement opportunities for implementation were higher nursing staff involvement and repeated intervention offering., Competing Interests: Disclosure SG reports participation in an advisory board concerning intravenous administration of temocillin in 2019.

Objectives: Guideline adherence is one of the most important objectives for antibiotic stewardship. The Dutch Working Party on Antibiotic Policy (SWAB) developed an online national guide (SWAB-ID) in 2006. Every Dutch hospital is offered the opportunity to customize the national version to their local context and distribute it through an independent website. We studied user data to see how often the guidelines on therapy, prophylaxis and medication are used., Methods: Data on usage between 19 June 2020 and 30 June 2022 were extracted through Google Analytics for the national site and the 53 hospitals using a customized version of the national guide. User data were divided into three main groups: users of the national guide SWAB-ID, and users of the sites of general hospitals and university hospitals., Results: A total of 1 837 126 searches were analysed, of which 1 393 681 (75.9%) concerned therapy, 111 774 (6.1%) prophylaxis and 331 671 (18%) medication. Of these searches, 456 854 (24.9%) were performed on the national site, 950 887 (51.8%) by general hospitals and 429 385 (23.4%) by university hospitals. The most commonly searched tracts among all user groups were lower respiratory tract (21.8%), kidney and urinary tract (16.6%) and skin and soft tissues (11.8%). The most commonly searched conditions were community-acquired pneumonia (15.3%), cystitis (13.5%) and sepsis (11.3%). The top ranked pages on medication differed for the three categories of users., Conclusions: The SWAB-ID antimicrobial guide is used extensively by both general and university hospitals. The online guide can help in prescribing therapy according to the guideline., (© The Author(s) 2023.

A practice guide to help nursing homes set up an antimicrobial stewardship (AMS) program was developed based on experiences gained during a project at one of the largest providers of elderly care in the South-east of the Netherlands. The guideline for the implementation of AMS in Dutch hospitals served as a starting point and were tailored to the unique characteristics of a nursing home setting. This practice guide offers recommendations and practical tools while emphasizing the importance of establishing a multidisciplinary approach to oversee AMS efforts. The recommendations and practical tools address various elements of AMS, including the basic conditions to initiate an AMS program and a comprehensive approach to embed an AMS program. This approach involves educating nurses and caregivers, informing volunteers and residents/their representatives, and the activities of an antibiotic team (A-team). The practice guide also highlights a feasible work process for the A-team. This process aims to achieve a culture of continuous learning and improvement that can enhance the overall quality of antibiotic prescribing rather than making individual adjustments to client prescriptions. Overall, this practice guide aims to help nursing homes establish an AMS program through collaborative efforts between involved physicians, pharmacists, clinical microbiologists, and infection control practitioners. The involved physician plays a crucial role in instilling a sense of urgency and developing a stepwise strategy., (© 2023. The Author(s).)

Abstract: This therapeutic drug monitoring (TDM) grand round describes a patient with serious valproic acid intoxication. A total valproic acid level of 844 mg/L and an unbound valproic acid level of 604 mg/L were observed. Meropenem was administered to enhance the clearance of valproic acid. This off-label usage of meropenem is based on the drug-drug interaction between carbapenems and valproic acid, which reduced the level of valproic acid within 24 hours after administration., (Copyright © 2022 Wolters Kluwer Health, Inc.

Objective: To investigate whether an electronic health record (EHR)-integrated decision tool, combined with supportive interventions, results in more appropriate antibiotic prescribing in nursing home (NH) residents with suspected urinary tract infection (UTI), without negative consequences for residents., Design: Cluster randomized controlled trial with NHs as the randomization unit; intervention group NHs received the EHR-integrated decision tool and supportive interventions, and control group NHs provided care as usual., Setting and Participants: 212 residents with suspected UTI, from 16 NHs in the Netherlands., Methods: Physicians collected data at index consultation (ie, UTI suspicion) and during a 21-day follow-up period (March 2019-March 2020). Overall antibiotic prescribing data at NH level, 12 months prior to and during the study, was derived from the electronic prescribing system. The primary study outcome was the percentage of antibiotic prescriptions for suspected UTI that was appropriate, at index consultation. Secondary study outcomes included changes in treatment decision, complications, UTI-related hospitalization, and mortality during follow-up; and pre-post study changes in antibiotic prescribing at the NH level., Results: 295 suspected UTIs were included (intervention group: 189; control group: 106). The between-group difference in appropriate antibiotic prescribing was 13% [intervention group: 62%, control group: 49%; adjusted odds ratio (OR) 1.43, 95% CI 0.57-3.62]. In both groups, complications (2% vs 3%), UTI-related hospitalization (2% vs 1%), and possible UTI-related mortality (2% vs 2%) were rare. The pre-post study difference in antibiotic prescriptions per 1000 resident-care days was -0.95 in the intervention group NHs and -0.05 in the control group NHs (P = .02)., Conclusion and Implications: Although appropriate antibiotic prescribing improved in the intervention group, this does not provide sufficient evidence for our multidisciplinary intervention. Despite this inconclusive result, our intervention could potentially still be effective, because we established a large reduction in the number of antibiotic prescriptions in the intervention group., (Copyright © 2021 The Authors.

Background Providing appropriate medication information to patients is of utmost importance for optimal pharmacotherapy. (Un)intentional miscommunication and information gaps resulting in unmet needs could negatively affect patient's ability to use their medication properly. Objective To identify the information needs and patient perceptions of the quality of medication information available in hospitals in the Netherlands. Setting Cardiology, oncology, or rheumatology department of five hospitals. Methods Adult cardiology, oncology, and rheumatology patients participated in this mixed-method study. Focus groups and individual interviews were held to identify patients' views on the medication information and their information needs. Outcomes were used to construct a questionnaire that was used in a survey among patients to compare existing medication information with patients' needs, and to judge the quality of the provided information. Main outcome measure Patients needs with medication information. Results Four themes derived from interviews with 44 patients: (1) Content; almost all patients acknowledged to receive insufficient information not meeting their personal needs. (2) Moment of delivery; patients were dissatisfied with the timing. (3) Method of delivery; patients highly preferred verbal and written information. (4) Contextual quality prerequisites that should be met according to patients; medication information should be accessible, comprehensive, reliable and understandable. A total of 352 patients completed the questionnaire. Almost all patients reported all items as important, whereas up to 74.6% patients were not informed. Up to half of the patients perceived verbal information from healthcare providers, written information of leaflets and folders of insufficient quality. Conclusion Patients attending Dutch hospitals have needs for extensive medication information, which should be tailored to their individual needs. According to patients the quality of medication information available in hospitals can be improved.

Background: Antibiotic overprescribing for suspected urinary tract infection (UTI) in nursing homes (NHs) is common. Typical clinical scenarios in which antibiotics are inappropriately prescribed include response to nonspecific signs and symptoms and/or a positive urine test in the absence of symptoms referable to the urinary tract. These and other scenarios for inappropriate antibiotic prescribing were addressed in a recent international Delphi study which resulted in the development of a decision tool for the empiric treatment of UTI in frail older adults. The aim of the current study is to implement this decision tool, by integrating it into the electronic health record (EHR) and providing education on its content and use, and to evaluate its effect on appropriate antibiotic prescribing. An additional aim is to evaluate the quality of the intervention and the implementation process., Methods: A cluster Randomized Controlled Trial (cRCT) is conducted in sixteen NHs and aims to include 897 residents diagnosed with suspected UTI. NHs in the intervention group use the EHR-integrated decision tool, and receive education for physicians and nursing staff; in the control group care as usual is provided. Data is collected through case report forms within the EHR at the day of diagnosis and at 3, 7, and 21 days thereafter. The primary outcome is appropriate antibiotic prescribing for suspected UTI at the day of diagnosis. Secondary outcomes include the course of symptoms, alternative diagnoses, treatment changes, complications, hospitalization, and mortality. Data on total antibiotic prescribing are additionally collected in the participating NHs 12 months before and during the study. Finally, the process evaluation combines cRCT data with questionnaires and qualitative interviews with NH professionals., Discussion: This is the first cRCT to evaluate the recently developed, international decision tool for empiric treatment of suspected UTI in NH residents. Study findings will elucidate the effect of the intervention on appropriate antibiotic prescribing for suspected UTI, and provide insight into the applicability of the decision tool in NHs in general and in specific subgroups of NH residents. With this study we aim to contribute to antibiotic stewardship efforts in long-term care., Trial Registration: The ANNA study was registered at the Netherlands Trial Register on 26 February 2019, with identification number NTR NL7555 .

Objectives: To determine trends, seasonality and the association between community antibiotic use and antimicrobial resistance (AMR) in Escherichia coli and Klebsiella pneumoniae in urinary tract infections., Methods: We analysed Dutch national databases from January 2008 to December 2016 regarding antibiotic use and AMR for nitrofurantoin, trimethoprim, fosfomycin and ciprofloxacin. Antibiotic use was expressed as DDD/1000 inhabitant-days (DID) and AMR was expressed as the percentage of resistance from total tested isolates. Temporal trends and seasonality were analysed with autoregressive integrated moving average (ARIMA) models. Each antibiotic use-resistance combination was cross-correlated with a linear regression of the ARIMA residuals., Results: The trends of DID increased for ciprofloxacin, fosfomycin and nitrofurantoin, but decreased for trimethoprim. Similar trends were found in E. coli and K. pneumoniae resistance to the same antibiotics, except for K. pneumoniae resistance to ciprofloxacin, which decreased. Resistance levels peaked in winter/spring, whereas antibiotic use peaked in summer/autumn. In univariate analysis, the strongest and most significant cross-correlations were approximately 0.20, and had a time delay of 3-6 months between changes in antibiotic use and changes in resistance. In multivariate analysis, significant effects of nitrofurantoin use and ciprofloxacin use on resistance to these antibiotics were found in E. coli and K. pneumoniae, respectively. There was a significant association of nitrofurantoin use with trimethoprim resistance in K. pneumoniae after adjusting for trimethoprim use., Conclusions: We found a relatively low use of antibiotics and resistance levels over a 9 year period. Although the correlations were weak, variations in antibiotic use for these four antibiotics were associated with subsequent variations in AMR in urinary pathogens., (© The Author(s) 2020.

Introduction: Taking consecutive antibiotic use into account is of importance to obtain insight in treatment within disease episodes, use of 2nd- and 3rd-choice antibiotics, therapy failure and/or side effects. Nevertheless, studies dealing with consecutive antibiotic use are scarce. We aimed at evaluating switch patterns in antibiotic use in the outpatient setting in the Netherlands., Methods: Outpatient antibiotic dispensing data was processed to antibiotic treatment episodes consisting of single prescriptions or consecutive prescriptions (2006 to 2014). Consecutive prescriptions were categorised into prolongations and switches. Switches were further analysed to obtain antibiotic switch percentages and trends over time. Outcomes were compared with recommendations of Dutch guidelines., Results: A total of 43,179,867 antibiotic prescriptions were included in the analysis, consisting of single prescriptions (95%), prolongations (2%) and switches (3%). The highest switch percentages were found for trimethoprim (7.6%) and nitrofurantoin (5.4%). For fosfomycin, ciprofloxacin, flucloxacillin and trimethoprim we found the highest yearly increase in switching. Amoxicillin/clavulanic acid was most often used as second antibiotic in a switch. A surprisingly high number of 2nd- and 3rd-choice antibiotics are prescribed as first antibiotic in a treatment., Conclusions: Although the actual reason for a switch is unknown, switch patterns can reveal problems concerning treatment failure and guideline adherence. In general, switch percentages of antibiotics in the Netherlands are low. The data contributes to the knowledge regarding antibiotic switch patterns in the outpatient setting.

Background Despite the potential of clinical practice guidelines to improve patient outcomes, adherence to guidelines by prescribers is inconsistent. Objective The aim of the study was to determine whether an approach of introducing an educational programme for prescribers in the hospital combined with audit and feedback by the hospital pharmacist reduces non-adherence of prescribing physicians to key pharmacotherapeutic guidelines. Setting This prospective intervention study with a before-after design evaluated patients at surgical, urological and orthopaedic wards. Method An educational program covering pain management, antithrombotics, fluid and electrolyte management, prescribing in case of renal insufficiency, application of radiographic contrast agents and surgical antibiotic prophylaxis was presented to prescribers on the participating wards. Hospital pharmacists performed medication safety consultations, combining medication review of patients who are at risk for drug related problems with visits to ward physicians. Main outcome measure The outcome measure was the proportion of the admissions of patients in which the physician did not adhere to one or more of the included guidelines. Difference was expressed in odds ratios (OR) with 95% confidence intervals (CI). Multivariable logistic regression analysis was performed. Results 1435 Admissions of 1378 patients during the usual care period and 1195 admissions of 1090 patients during the intervention period were included. Non-adherence was observed significantly less often during the intervention period [21.8% (193/886)] as compared to the usual care period [30.5% (332/1089)]. The adjusted OR was 0.61 (95% CI 0.49-0.76). Conclusion This study shows that education and support of the prescribing physician can reduce guideline non-adherence at surgical wards.

Objectives: : Residents living in a long-term care facility (LTCF) are more susceptible to infections. Treatment with antimicrobials is sometimes necessary; however, antibiotic use is considered one of the most important drivers of the development of antibiotic resistance. Surveillance data on antibiotic use in these LTCFs are necessary to get more insight into these patterns. The objective of this study was to describe antibiotic use in LTCFs in the Netherlands., Methods: : One hundred and seventy-seven LTCFs in the Netherlands were contacted and asked to participate in a study concerning antibiotic resistance and antibiotic use. Associated pharmacies were asked to provide data about systemic antibiotic use for each participating LTCF location over 1 year. Results on antibiotic use are reported here., Results: : Antibiotic use data from 96 LTCFs were collected from the pharmacies, and 68 of these LTCFs completed additional questionnaires on general characteristics of their location. Mean total use of systemic antimicrobials was 73 DDDs/1000 residents per day (range 2-197 DDDs/1000 residents per day). Co-amoxiclav (23 DDDs/1000 residents/day, range 0-70) was used the most, followed by nitrofurantoin derivatives (12 DDDs/1000 residents/day, range 0-38) and fluoroquinolones (12 DDDs/1000 residents/day, range 0-52). Statistical analysis revealed no significant correlations between the LTCF characteristics and the level of antibiotic use., Conclusions: There was a high use of broad-spectrum antimicrobials, with a large variation in total antibiotic use between individual locations. Further analysis of more in-depth data and possible influencing factors is needed., (© The Author 2017.

Quality Problem: Inappropriate antibiotic use drives development of antimicrobial resistance. Worldwide, guideline adherence for antibiotic treatment of infectious disease is far from optimal. Insight in prescribing quality is pivotal for healthcare professionals and policy makers to intervene appropriately., Initial Assessments: European countries uniformly monitor antibiotic use, which is reported yearly by the European Centre for Disease Prevention and Control. Unfortunately, this has not had enough impact to decrease prescribing and resistance levels., Choice of Solution: Quality indicators (QIs) could provide better insight in prescribing quality and enable benchmarking to other countries; this could trigger action to improve antimicrobial prescribing. European Surveillance of Antimicrobial Consumption (ESAC) proposed 12 antibiotic QIs., Implementation: Trends in use of antibiotic subgroups and the 12 ESAC QI values were determined for Dutch primary care (2004-2013); outcomes were compared to other European countries. Dutch antibiotic use is low within the European context. Nitrofurantoin use is higher than the European average, use of small-spectrum antibiotics lowers. Use of macrolides, quinolones and amoxicillin/clavulanate declined, which was not supported by the broad/narrow QI results., Evaluation: QIs expressing antibiotic subgroup use in Defined Daily Doses/1000 inhabitants/day, particularly small-spectrum and non-first choices, provide proper insight in prescribing quality and are useful for benchmarking purposes. QIs measuring percentages were not considered useful. The broad/narrow ratio could be more informative when adjusted to national guidelines, or when more antibiotic subgroups are included based on better European consensus., Lessons Learnt: Benchmarking the above mentioned Dutch QI values to other countries provides direction for three specific strategies to further improve Dutch antibiotic prescribing practice., (© The Author 2016.

Objectives: The objective of this study was to assess carriage of antimicrobial-resistant commensal microorganisms, i.e. Escherichia coli and Staphylococcus aureus, and its predictors in long-term-care facilities (LTCFs)., Methods: Nasal swabs and/or urine or incontinence samples were collected from participating residents in 111 LTCFs and tested for the presence of S. aureus and/or E. coli, respectively. Antimicrobial resistance to eight antimicrobials was linked to antimicrobial usage in the year preceding sampling and to LTCF characteristics. Using multilevel logistic regression, predictors of carriage of ESBL-producing E. coli in LTCFs were identified., Results: S. aureus was identified in 1269/4763 (26.6%) nasal swabs, including 13/4763 (0.3%) MRSA carriers in 9/107 (8%) LTCFs. Of the 5359 urine/incontinence samples, 2934 (55%) yielded E. coli, including 123 (4.2%) producing ESBL, which were found in 53/107 locations (range 1%-33%). For all but one antimicrobial (i.e. nitrofurantoin) >20% of isolated E. coli were resistant. Multilevel multivariable logistic regression identified two predictors of carriage of ESBL-producing E. coli: (i) antimicrobial usage (OR 1.8, 95% CI 1.1-3.0 for each extra 50 DDD/1000 residents/day); and (ii) presence of MRSA carriers in the LTCFs (OR 2.4, 95% CI 1.0-5.6)., Conclusions: The low proportion of 4.2% ESBL-producing E. coli and the low prevalence of 0.3% MRSA carriage found in LTCF residents suggest that Dutch LTCFs are not yet an important reservoir of MDR potential pathogens. Nevertheless, the large variation between LTCFs warrants close monitoring of antimicrobial resistance in LTCFs. Integrated surveillance, i.e. linking data sources on antimicrobial usage, microbiological testing, clinical background data and epidemiological data, is needed., (© The Author 2016.

Background: Antimicrobial stewardship is advocated to improve the quality of antimicrobial use. We did a systematic review and meta-analysis to assess whether antimicrobial stewardship objectives had any effects in hospitals and long-term care facilities on four predefined patients' outcomes: clinical outcomes, adverse events, costs, and bacterial resistance rates., Methods: We identified 14 stewardship objectives and did a separate systematic search for articles relating to each one in Embase, Ovid MEDLINE, and PubMed. Studies were included if they reported data on any of the four predefined outcomes in patients in whom the specific antimicrobial stewardship objective was assessed and compared the findings in patients in whom the objective was or was not met. We used a random-effects model to calculate relative risk reductions with relative risks and 95% CIs., Findings: We identified 145 unique studies with data on nine stewardship objectives. Overall, the quality of evidence was generally low and heterogeneity between studies was mostly moderate to high. For the objectives empirical therapy according to guidelines, de-escalation of therapy, switch from intravenous to oral treatment, therapeutic drug monitoring, use of a list of restricted antibiotics, and bedside consultation the overall evidence showed significant benefits for one or more of the four outcomes. Guideline-adherent empirical therapy was associated with a relative risk reduction for mortality of 35% (relative risk 0·65, 95% CI 0·54-0·80, p<0·0001) and for de-escalation of 56% (0·44, 0·30-0·66, p<0·0001). Evidence of effects was less clear for adjusting therapy according to renal function, discontinuing therapy based on lack of clinical or microbiological evidence of infection, and having a local antibiotic guide. We found no reports for the remaining five stewardship objectives or for long-term care facilities., Interpretation: Our findings of beneficial effects on outcomes with nine antimicrobial stewardship objectives suggest they can guide stewardship teams in their efforts to improve the quality of antibiotic use in hospitals., Funding: Dutch Working Party on Antibiotic Policy and Netherlands National Institute for Public Health and the Environment., (Copyright © 2016 Elsevier Ltd.

Objectives: To evaluate the effect of tailored interventions on the appropriateness of decisions to prescribe or withhold antibiotics, antibiotic use and guideline-adherent antibiotic selection in nursing homes (NHs)., Methods: We conducted a quasi-experimental study in 10 NHs in the Netherlands. A participatory action research (PAR) approach was applied, with local stakeholders in charge of selecting tailored interventions based on opportunities for improved antibiotic prescribing that they derived from provided baseline data. An algorithm was used to evaluate the appropriateness of prescribing decisions, based on infections recorded by physicians. Effects of the interventions on the appropriateness of prescribing decisions were analysed with a multilevel logistic regression model. Pharmacy data were used to calculate differences in antibiotic use and recorded infections were used to calculate differences in guideline-adherent antibiotic selection., Results: The appropriateness of 1059 prescribing decisions was assessed. Adjusting for pre-test differences in the proportion of appropriate prescribing decisions (intervention, 82%; control, 70%), post-test appropriateness did not differ between groups (crude: P = 0.26; adjusted for covariates: P = 0.35). We observed more appropriate prescribing decisions at the start of data collection and before receiving feedback on prescribing behaviour. No changes in antibiotic use or guideline-adherent antibiotic selection were observed in intervention NHs., Conclusions: The PAR approach, or the way PAR was applied in the study, was not effective in improving antibiotic prescribing behaviour. The study findings suggest that drawing prescribers' attention to prescribing behaviour and monitoring activities, and increasing use of diagnostic resources may be promising interventions to improve antibiotic prescribing in NHs., (© The Author 2015.

Objective: To develop an instrument for evaluating the quality of antibiotic management of patients with community-acquired pneumonia (CAP) applicable in a middle-income developing country., Method: A previous study and Indonesian guidelines were reviewed to derive potential quality of care indicators (QIs). An expert panel performed a two-round Delphi consensus procedure on the QI's relevance to patient recovery, reduction of antimicrobial resistance and cost containment. Applicability in practice, including reliability, feasibility and opportunity for improvement, was determined in a data set of 128 patients hospitalised with CAP in Semarang, Indonesia., Results: Fifteen QIs were selected by the consensus procedure. Five QIs did not pass feasibility criteria, because of inappropriate documentation, inefficient laboratory services or patient factors. Three QIs provided minor opportunity for improvement. Two QIs contradicted each other; one of these was considered not valid and excluded. A final set of six QIs was defined for use in the Indonesian setting., Conclusion: Using the Delphi method, we defined a list of QIs for assessing the quality of care, in particular antibiotic treatment, for CAP in Indonesia. For further improvement, a modified Delphi method that includes discussion, a sound medical documentation system, improvement of microbiology laboratory services, and multi-center applicability tests are needed to develop a valid and applicable QI list for the Indonesian setting., (© 2014 John Wiley & Sons Ltd.)

Objective: To investigate the appropriateness of decisions to prescribe or withhold antibiotics for nursing home (NH) residents with infections of the urinary tract (UTI), respiratory tract (RTI), and skin (SI)., Design: Prospective study., Setting: Ten NHs in the central-west region of the Netherlands., Participants: Physicians providing medical care to NH residents., Measurements: Physicians completed a registration form for any suspected infection over an 8-month period, including patient characteristics, signs and symptoms, and treatment decisions. An algorithm, developed by an expert panel and based on national and international guidelines, was used to evaluate treatment decisions for appropriateness of initiating or withholding antibiotics., Results: Appropriateness of 598 treatment decisions was assessed. Overall, 76% were appropriate, with cases that were prescribed antibiotics judged less frequently "appropriate" (74%) compared with cases in which antibiotics were withheld (90%) (P = .003). Decisions around UTI were least often appropriate (68%, compared with 87% for RTI and 94% for SI [P < .001]). The most common situations in which antibiotic prescribing was considered inappropriate were those indicative of asymptomatic bacteriuria or viral RTI., Conclusion: Although the rate of appropriate antibiotic prescribing in Dutch NHs is relatively high compared with previous studies in other countries, our results suggest that antibiotic consumption can be reduced by improving appropriateness of treatment decisions, especially for UTI. Given the current antibiotic resistance developments in long-term care facilities, interventions reducing antibiotic use for asymptomatic bacteriuria and viral RTI are warranted., (Copyright © 2015 AMDA – The Society for Post-Acute and Long-Term Care Medicine.

Objective: Most pneumonia treatment guidelines recommend that prior outpatient antibiotic treatment should be considered when planning inpatient antibiotic regimen. Our purpose was to study in patients admitted for community-acquired pneumonia the mode of continuing antibiotic treatment at the outpatient to inpatient transition and the subsequent clinical course., Design: Retrospective cohort study., Setting: Dutch PHARMO Record Linkage System., Participants: 7323 patients aged >18 years and hospitalised with pneumonia in the Netherlands between 2004 and 2010., Main Study Parameter: We identified all prescribed antibiotics prior to, during and after hospitalisation. In case of prior outpatient treatment, the continuation of antibiotic treatment on admission was categorised as: no atypical coverage > no atypical coverage; atypical coverage > atypical coverage; no atypical coverage > atypical coverage; and atypical coverage > no atypical coverage., Main Outcome Measures: Length of hospital stay, in-hospital mortality and readmission within 30 days., Results: Twenty-two per cent of the patients had received prior outpatient treatment, of which 408 (25%) patients were switched on admission to antibiotics with atypical coverage. There were no differences in length of hospital stay, in-hospital mortality or readmission rate between the four categories of patients with prior outpatient treatment. The adjusted HR for adding atypical coverage versus no atypical coverage was 0.91 (95% CI 0.55 to 1.51) for time to discharge. For in-hospital mortality and readmission within 30 days, the adjusted ORs were 1.09 (95% CI 0.85 to 1.34) and 0.59 (95% CI 0.30 to 1.18), respectively., Conclusions: This study found no association between mode of continuing antibiotic treatment at the outpatient to inpatient transition and relevant clinical outcomes. In particular, adding atypical coverage in patients without prior atypical coverage did not influence the outcome., (Published by the BMJ Publishing Group Limited.

Background: An important requirement for an effective antibiotic stewardship program is the ability to measure appropriateness of antibiotic use. The aim of this study was to develop quality indicators (QIs) that can be used to measure appropriateness of antibiotic use in the treatment of all bacterial infections in hospitalized adult patients., Methods: A RAND-modified Delphi procedure was used to develop a set of QIs. Potential QIs were retrieved from the literature. In 2 questionnaire mailings with an in-between face-to-face consensus meeting, an international multidisciplinary expert panel of 17 experts appraised and prioritized these potential QIs., Results: The literature search resulted in a list of 24 potential QIs. Nine QIs describing recommended care at patient level were selected: (1) take 2 blood cultures, (2) take cultures from suspected sites of infection, (3) prescribe empirical antibiotic therapy according to local guideline, (4) change empirical to pathogen-directed therapy, (5) adapt antibiotic dosage to renal function, (6) switch from intravenous to oral, (7) document antibiotic plan, (8) perform therapeutic drug monitoring, and (9) discontinue antibiotic therapy if infection is not confirmed. Two QIs describing recommended care at the hospital level were also selected: (1) a local antibiotic guideline should be present, and (2) these local guidelines should correspond to the national antibiotic guidelines., Conclusions: The selected QIs can be used in antibiotic stewardship programs to determine for which aspects of antibiotic use there is room for improvement. At this moment we are testing the clinimetric properties of these QIs in 1800 hospitalized patients, in 22 Dutch hospitals., (© The Author 2014.

Background: Outcomes in patients with sepsis are better if initial empirical antimicrobial use is appropriate. Several studies have shown that adherence to guidelines dictating appropriate antimicrobial use positively influences clinical outcome, shortens length of hospital stay and contributes to the containment of antibiotic resistance.Quality indicators (QIs) can be systematically developed from these guidelines to define and measure appropriate antimicrobial use. We describe the development of a concise set of QIs to assess the appropriateness of antimicrobial use in adult patients with sepsis on a general medical ward or Intensive Care Unit (ICU)., Methods: A RAND-modified, five step Delphi procedure was used. A multidisciplinary panel of 14 experts appraised and prioritized 40 key recommendations from within the Dutch national guideline on antimicrobial use for adult hospitalized patients with sepsis (http://www.swab.nl/guidelines). A procedure to select QIs relevant to clinical outcome, antimicrobial resistance and costs was performed using two rounds of questionnaires with a face-to-face consensus meeting between the rounds over a period of three months., Results: The procedure resulted in the selection of a final set of five QIs, namely: obtain cultures; prescribe empirical antimicrobial therapy according to the national guideline; start intravenous drug therapy; start antimicrobial treatment within one hour; and streamline antimicrobial therapy., Conclusion: This systematic, stepwise method, which combined evidence and expert opinion, led to a concise and therefore feasible set of QIs for optimal antimicrobial use in hospitalized adult patients with sepsis. The next step will entail subjecting these quality indicators to an applicability test for their clinimetric properties and ultimately, using these QIs in quality-improvement projects. This information is crucial for antimicrobial stewardship teams to help set priorities and to focus improvement.

Introduction: The common occurrence of infectious diseases in nursing homes and residential care facilities may result in substantial antibiotic use, and consequently antibiotic resistance. Focusing on these settings, this article aims to provide a comprehensive overview of the literature available on antibiotic use, antibiotic resistance, and strategies to reduce antibiotic resistance., Methods: Relevant literature was identified by conducting a systematic search in the MEDLINE and EMBASE databases. Additional articles were identified by reviewing the reference lists of included articles, by searching Google Scholar, and by searching Web sites of relevant organizations., Results: A total of 156 articles were included in the review. Antibiotic use in long term care facilities is common; reported annual prevalence rates range from 47% to 79%. Part of the prescribed antibiotics is potentially inappropriate. The occurrence of antibiotic resistance is substantial in the long term care setting. Risk factors for the acquisition of resistant pathogens include prior antibiotic use, the presence of invasive devices, such as urinary catheters and feeding tubes, lower functional status, and a variety of other resident- and facility-related factors. Infection with antibiotic-resistant pathogens is associated with increased morbidity, mortality, and health care costs. Two general strategies to reduce antibiotic resistance in long term care facilities are the implementation of infection control measures and antibiotic stewardship., Conclusion: The findings of this review call for the conduction of research and the development of policies directed at reducing antibiotic resistance and its subsequent burden for long term care facilities and their residents., (Copyright © 2012 American Medical Directors Association.

Background: Medication errors are a leading cause of patient harm. Many of these errors result from an incomplete overview of medication either at a patient's referral to or at discharge from the hospital. One solution is medication reconciliation, a formal process in which health care professionals partner with patients to ensure an accurate and complete transfer of medication information at interfaces of care. In 2007, the Dutch government compelled hospitals to implement a bundle concerning medication reconciliation at hospital admission and discharge. But to date many hospitals have failed to implement this bundle fully. The aim of this study was to gain insight into the barriers and drivers of the implementation process., Methods: We performed face to face, semi-structured interviews with twenty health care professionals and managers from several departments at a 953 bed university hospital in the Netherlands and also from the surrounding community health services. The interviews were analysed using a combined theoretical framework of Grol and Cabana to classify the drivers and barriers identified., Results: There is lack of awareness and insufficient knowledge of health care professionals about the health care problem and the bundle medication reconciliation. These result in a lack of support for implementing the bundle. In addition clinicians are reluctant to reallocate tasks to nurses or pharmacy technicians. Another major barrier is a lack of communication, understanding and collaboration between hospital and community caregivers. The introduction of more competitive market forces has made matters worse. Major drivers are a good implementation plan, patient awareness, and obligation by the government., Conclusions: We identified a wide range of barriers and drivers which health care professionals believe influence the implementation of medication reconciliation. This reflects the complexity of implementation. Implementation can be improved if these factors are adequately addressed. The feasibility and effectiveness of these strategies should be tested in controlled trails.

As in other countries, the growing resistance to antimicrobial drugs is also taking place in the Netherlands; the primary cause being the total consumption of antibiotics. Given the steady decline in the discovery of new antimicrobials, better use of agents currently available is warranted. Guidelines describing appropriate antimicrobial therapy play an important role; however, such guidelines are not optimally used in daily practice. Quality indicators can be used to assess the quality of antibiotic treatment and evaluate the impact of interventions aimed at improving care. Quality indicators used for evaluating treatment of infections of the respiratory and urinary tracts are developed previously. A comprehensive set of indicators that could be used to assess the quality of hospital antibiotic use for all bacterial infections has not yet been developed. A new project has recently been started in the Netherlands called 'The development of Reliable generic quality Indicators for the optimalisation of ANTibiotic use in the hospital' (RIANT study) for developing such a set of comprehensive indicators.

Objectives: This paper reports on a pilot study examining the incidence of nurses' errors in preparation and administration of intravenous drugs. Furthermore, the study aimed to evaluate the short-term effects of implementation of a new protocol for preparation and administration of intravenous drugs., Setting: Two nursing departments of internal medicine at a 953 beds University Medical Centre in The Netherlands., Methods: By means of a prospective, quasi-experimental design, nurses were observed during the process of preparation and administration of intravenous drugs. Observation was performed before and after the implementation of a new protocol. Seventy-two nurses at two nursing departments were observed during the study., Main Outcome Measure: A mean pre-test and post-test quality score at two departments of internal medicine., Results: At baseline, average quality scores for nurses at the two departments were 64 (intervention ward) and 67 (control ward) on a 0-100 quality scale. The pre-test quality scores were not statistically significant for the two nursing wards (T = 1.36, df = 55, P = 0.18). After the implementation of the new protocol, nurses at the intervention ward scored better (72) than nurses at the control ward (69). The mean score at the intervention ward was significantly higher than the score in nurses of the control ward (T = -2.20, df = 53, P = 0.04)., Conclusions: The number of errors in the preparation and administration of intravenous drugs is high. This study shows that implementing a protocol for the preparation and administration of these drugs can reduce the number of errors.

Background: Physician adherence to key recommendations of guidelines for community-acquired pneumonia (CAP) is often not optimal. A better understanding of factors influencing optimal performance is needed to plan effective change., Methods: The authors used semistructured interviews with care providers in three Dutch medium-sized hospitals to qualitatively study and understand barriers to appropriate antibiotic use in patients with CAP. They discussed recommendations about the prescription of empirical antibiotic therapy that adheres to the guidelines, timely administration of antibiotics, adjusting antibiotic dosage to accommodate decreased renal function, switching and streamlining therapy, and blood and sputum culturing. The authors then classified the barriers each recommendation faced into categories using a conceptual framework (Cabana)., Results: Eighteen interviews were performed with residents and specialists in pulmonology and internal medicine, with medical microbiologists and a clinical pharmacist. Two additional multidisciplinary small group interviews which included nurses were performed. Each guideline recommendation elicited a different type of barrier. Regarding the choice of guideline-adherent empirical therapy, treating physicians said that they worried about patient outcome when prescribing narrow-spectrum antibiotic therapy. Regarding the timeliness of antibiotic administration, barriers such as conflicting guidelines and organisational factors (for example, delayed laboratory results, antibiotics not directly available, lack of time) were reported. Not streamlining therapy after culture results became available was thought to be due to the physicians' attitude of "never change a winning team"., Conclusions: Efforts to improve the use of antibiotics for patients with CAP should consider the range of barriers that care providers face. Each recommendation meets its own barriers. Interventions to improve adherence should be tailored to these factors.

Background: Timely administration of the first dose, dosage adjustment to renal function, switch from intravenous to oral administration, and streamlining are important aspects of rational antibiotic prescription. The goals of this study were to investigate all of these variables, compare them with predefined quality standards, and implement improvement with specific interventions., Methods: At the departments of internal medicine, surgery, and neurology and the emergency department of a tertiary referral university medical center, all consecutive patients receiving therapeutic antibiotics were enrolled. Dosages, timing of first doses, dosing intervals, administration routes, and adjustment of the chosen drug to clinical data were investigated. After the preintervention period, barriers to change were identified, followed by specific interventions and a postintervention measurement., Results: In the preintervention and postintervention periods, 247 and 250 patients were enrolled, receiving 563 and 598 antibiotic prescriptions, respectively. The mean time from the order to first dose at the wards improved from 2.7 to 1.7 hours in potentially severe cases (P =.003). Dosage adjustment to renal function remained unchanged at 45% vs 52% (P =.09) of cases where necessary. Switching of therapy from intravenous to oral improved from 46% to 62% (P =.03) and was performed a mean of 1.6 days earlier (P =.002). Streamlining was performed correctly in most cases, and thus no interventions were necessary., Conclusions: Timing of antibiotic therapy and switch therapy may be improved with a combination of interventions. To improve poor adjustment of dosing to renal function, other strategies are needed. In our setting, streamlining was already correct in most cases.
