Easily available adjustment criteria for the comparison of antibiotic consumption in a hospital setting: experience in France

Clinical Microbiology and Infection, 2010

Hospitals in France are encouraged to monitor antibiotic consumption (AbC) and it is known that this differs among hospitals. The aim of the current study was to identify relevant and easily available adjustment criteria for the purpose of benchmarking. We analysed data from 34 public non-teaching hospitals and 43 private hospitals located in southwestern France and overseas departments using retrospective data from 2005. This study investigated the relationship between AbC expressed as defined daily doses per 1000 patient-days (DDD/1000 PDs) or per 100 admissions (DDD/100 admissions) and the number of venous central lines, the number of episodes of bacteraemia and various hospital characteristics. The relationship was tested using multiple linear analyses. The median total AbC in public hospitals was 395 DDD/1000 PDs (range, 196-737) and 341 DDD/100 admissions (range, 180-792). In private hospitals this was 422 DDD/1000 PDs (range, 113-717) and 212 DDD/100 admissions (range, 38-510). The best model for public hospitals included the proportion of PDs in surgery, intensive care and medical wards and explained 84% of the variability in AbC expressed as DDD/1000 PDs. For private hospitals, the mean length of stay and the proportion of PDs in surgery and medical wards explained 68% of the variability in AbC expressed as DDD/100 admissions. Overall, this French experience shows that relevant adjustment criteria for the comparison among hospitals are easily available. It is important that each country establish its own model considering the intrinsic peculiarities of the hospital system and taking into account both indicators (DDD/1000 PDs or DDD/100 admissions) to design the best model.

A Hospitalwide Intervention Program to Optimize the Quality of Antibiotic Use: Impact on Prescribing Practice, Antibiotic Consumption, Cost Savings, and Bacterial Resistance

Clinical Infectious Diseases, 2003

Several findings from Argentina provide compelling evidence of the need for more rational use of antimicrobial agents. Thus, a multidisciplinary antimicrobial treatment committee for the development of a hospital-wide intervention program was formed to optimize the quality of antibiotic use in hospitals. Four successive steps were developed during 6-month periods: baseline data collection, introduction of a prescription form, education, and prescribing control. Sustained reduction of drug consumption was shown during the study ( ; ). Total cost savings was US$913,236. To estimate the consumption of cefepime and 2 R p 0.6885 P p .01 aminopenicillin-sulbactam in relation to that of the third-generation cephalosporins, 2 indices were calculated: Icfp and Iams, respectively. Decreasing resistance to ceftriaxone by Proteus mirabilis and Enterobacter cloacae proved to be associated with increasing Icfp. Decreasing rates of methicillin-resistant Staphylococcus aureus were related to increasing Iams. The present study indicates that a systematic program performed by a multidisciplinary team is a cost-effective strategy for optimizing antibiotic prescribing.

Antibiotic policy: a tool for controlling resistance of hospital pathogens

Clinical Microbiology and Infection, 1999

Multiresistant Gram-negative bacilli, including strains of Klebsiella pneumoniae, Enterobacter spp, Acinetobacter baumannii and Pseudomonas aeruginosa, resistant to broad spectrum beta-lactams, aminoglycosides and fluoroquinolones, are recovered at increasing frequency from patients suffering from nosocomial infections, particularly from those receiving intensive care. The emergence and spread of resistant pathogens to endemic and epidemic levels has frequently been related in time and place to the intensive use of antibiotics to which these microorganisms have developed resistance, notably third generation cephalosporins and fluoroquinolones. Recent investigations have indicated that the prevalence of resistance can be reduced by scheduled changes of empiric treatment regimens, involving discontinuation of intensively prescribed drugs and substitution with newly introduced antibiotics of another class to which the prevalent resistant strains remain susceptible. Among these drugs, penicillins---beta-lactamase inhibitor combinations, 'fourth generation' cephalosporins and, where little used previously, fluoroquinolones, have been introduced successfully in high risk units where ceftazidime-resistant strains of K.pneumoniae, Enterobacter and Citrobacter spp or glycopeptide-resistant enterococci had become highly prevalent. However, these studies do not demonstrate a direct causal relationship between changes in prescribing practices and ecological improvements, because their observational design cannot be controlled. In most studies, several important factors influencing the dynamics of resistance were not monitored and the relative contribution of decreased emergence versus control of cross-transmission to the improved susceptibility rates is not clear. We propose that additional long-term studies are required to better track the ecological impact and to determine the optimal modalities of programmed changes of antibiotic prescribing as an antibiotic resistance prevention or control strategy.

Antibiotic usage in south-western French hospitals: trends and association with antibiotic stewardship measures

Journal of Antimicrobial Chemotherapy, 2011

Objectives: French hospitals are urged by health authorities to develop antibiotic stewardship (ABS) programmes in order to improve antibiotic use and to decrease their consumption. We performed a longitudinal survey to describe ABS measures implementation and antibiotic use and to study relationships between ABS measures and trends in antibiotic use between 2005 and 2009. Methods: Data on ABS, antibiotic use and activity were retrospectively collected by questionnaires sent to hospitals voluntarily participating in the southwestern France network. ABS measures covered organization, resources, restrictive and persuasive actions. Antibiotic use was retrieved from pharmacy records and expressed as the number of defined daily doses/1000 patient-days according to national and WHO guidelines using 2009 defined daily dose values to monitor trends. Relationships between ABS measures and antibiotic use were studied by multivariate logistic regression. Results: Between 2005 and 2009, the degree of implementation of ABS increased in the 74 participating hospitals. Antibiotic use remained stable, with variations according to hospital groups and antibiotic classes. In hospitals with more ABS measures, antibiotic use in general and fluoroquinolone use tended to remain stable or to decrease. Educational activities were associated with a decrease in fluoroquinolone use in the univariate analysis. In the multivariate analysis, practice audits and time dedicated by the antibiotic advisor were significantly associated with a decrease in total antibiotic use and fluoroquinolone use, respectively. Conclusions: This first longitudinal study, in 74 hospitals, showed that human resources and persuasive ABS measures, in the context of a multidisciplinary approach, are helpful in controlling total antibiotic and fluoroquinolone use.

Antibiotic use in 530 French hospitals: results from a surveillance network at hospital and ward levels in 2007

Journal of Antimicrobial Chemotherapy, 2010

Objectives: Antibiotic use in French hospitals is among the highest in Europe. A study was carried out to describe antibiotic consumption for inpatients at hospital and at ward levels. Methods: Data were voluntarily collected retrospectively by 530 hospitals accounting for 40 million patientdays (PD) on the following: antibacterials for systemic use [J01 class of the WHO Anatomical Therapeutic Chemical (ATC) classification, defined daily doses (DDD) system, 2007], rifampicin and oral imidazole derivatives, expressed in number of DDD and number of PD in 2007. Consumption was expressed in DDD/1000 PD. Results: Median antibiotic use ranged from 60 DDD/1000 PD in long-term care (LTC) and psychiatric hospitals to 633 DDD/1000 PD in teaching hospitals. Penicillins and b-lactamase inhibitors combinations were the most frequently used antibiotics, accounting for 26% of total use in cancer hospitals to 40% in LTC/psychiatric hospitals. Glycopeptides and carbapenems were mostly used in cancer and teaching hospitals. Level of consumption and pattern of use differed according to clinical ward from 60 DDD/1000 PD in psychiatric wards up to 1466 DDD/ 1000 PD in intensive care units (ICUs). In medicine, surgery, ICU and rehabilitation wards, fluoroquinolones accounted for 13%-19% of the total use. Conclusions: This multicentre survey provided detailed information on antibiotic use in a large sample of hospitals and wards, allowing relevant comparisons and benchmarking. Analysis of consumption at the ward level should help hospitals to target practice audits to improve antibiotic use.

Antibiotic control measures in Dutch secondary care hospitals

The Netherlands journal of medicine, 2005

Control measures for the use of antibiotics are essential because of the potential harmful consequences of side effects. Various methods have been developed to help curb undesirable antibiotic prescription. We performed a survey in Dutch secondary care hospitals (response rate 73%) to make an inventory of these measures and elucidate possible shortcomings. Almost every hospital was using an antibiotic formulary (97%), sometimes supported by extra restrictions in antibiotic choice (55%). Local practice guidelines (95%) were commonly present, but effective implementation, for example using intranet applications, could be improved (21%). National guidelines had received little attention in the composition process of local guidelines (19%). Other measures such as educational programmes for specialists (11%) and feedback on antibiotic prescription (52%) remained largely underused, although their effective implementation may optimise antibiotic prescription in hospitals.

Hospital- and patient-related factors associated with differences in hospital antibiotic use: analysis of national surveillance results

Antimicrobial resistance and infection control, 2014

Surveillance data of antibiotic use are increasingly being used for benchmarking purposes, but there is a lack of studies dealing with how hospital- and patient-related factors affect antibiotic utilization in hospitals. Our objective was to identify factors that may contribute to differences in antibiotic use. Based on pharmacy sales data (2006-2011), use of all antibiotics, all penicillins, and broad-spectrum antibiotics was analysed in 22 Health Enterprises (HEs). Antibiotic utilization was measured in World Health Organisation defined daily doses (DDDs) and hospital-adjusted (ha)DDDs, each related to the number of bed days (BDs) and the number of discharges. For each HE, all clinical specialties were included and the aggregated data at the HE level constituted the basis for the analyses. Fourteen variables potentially associated with the observed antibiotic use - extracted from validated national databases - were examined in 12 multiple linear regression models, with four differ...

Evaluation of antibiotic use in a hospital with an antibiotic restriction policy

International Journal of Antimicrobial Agents, 2003

The study was designed to evaluate rational antibiotic use in relation to diagnosis and bacteriological findings. All hospitalized patients who received antibiotics were evaluated by a cross-sectional study. Of the 713 patients hospitalized, 281 (39.4%) patients received 377 antibiotics. Among 30 different antibiotics the most frequently requested were first generation cephalosporins (19.9%), ampicillin Á/sulbactam (19.1%) and aminoglycosides (11.7%). Antibiotic use was appropriate in 64.2% of antibiotic requests. In analysis of appropriate use, a request after an infectious diseases consultation was a frequent reason (OR 0/14, P B/0.001, CI0/ 0.02 Á/0.24). Antibiotics requested in conjunction with susceptibility results were found to be more appropriate than those ordered empirically (OR 0/4.5, P0/0.017, CI0/0.06 Á/0.76). Inappropriate antibiotic use was significantly higher among unrestricted antibiotics than restricted ones (P B/0.001). Irrational antibiotic use was high for unrestricted antibiotics. Additional interventions such as postgraduate training programmes and elaboration of local guidelines could be beneficial. #

How to measure hospital antibiotic consumption: comparison of two methods from data surveillance in France

JAC-Antimicrobial Resistance

Background Antibiotic use (ABU) surveillance in healthcare facilities (HCFs) is essential to guide stewardship. Two methods are recommended: antibiotic consumption (ABC), expressed as the number of DDD/1000 patient-days; and prevalence of antibiotic prescription (ABP) measured through point prevalence surveys. However, no evidence is provided about whether they lead to similar conclusions. Objectives To compare ABC and ABP regarding HCF ranking and their ability to identify outliers. Methods The comparison was made using 2012 national databases from the antibiotic surveillance network and prevalence study. HCF rankings according to each method were compared with Spearman’s correlation coefficient. Analyses included the ABU from entire HCFs as well as according to type, clinical ward and by antibiotic class and specific molecule. Results A total of 1076 HCFs were included. HCF rankings were strongly correlated in the whole cohort. The correlation was stronger for HCFs with a higher n...
