Politique d'utilisation des antibiotiques : état des lieux dans 99 établissements de santé de l'interrégion Sud-Ouest

[Quality of antibiotic (fluoroquinolons, aminosids and amoxicillin-clavulanic acid) prescription in a French teaching hospital]

OBJECTIVES

To assess the quality of prescription of fluoroquinolons, aminosids and amoxicillin-clavulanic acids in medicine departments.

METHODS

Data on target antibiotic prescription were collected on a given day and confronted to local recommendations and literature guidelines. Evaluation of antibiotic therapy was done by assessing molecule choice, administration conditions (dosages, route and administration schedule, treatment duration), reassessment of treatments 48-72 h later, dose adaptation of aminosids depending on serum monitoring.

RESULTS

Sixty-three patients were included and 67 "target" antibiotics were prescribed. Prevalence of antibiotic-treated patients was 24.4%, and 14.6% for "target" antibiotic-treated patients. Antibiotic choice was appropriate in 67% of prescriptions. Dosages were adequates in 94% of case and administration schedule in 97% of cases. The oral route administration as soon as possible was applied to half of patients. Treatment duration were respected for 94% of prescriptions. Reassessment of antibiotic therapy 48-72 h later was realized in 66% of cases. Dose adaptation of aminosids, when necessary, was realized on one third of cases. For all the quality criteria assessed, the overall frequency of prescription conformity was 44%.

CONCLUSION

Large diffusion of protocols, systematic reassessment of treatments at 48-72 h, promotion of training sessions for new prescribers in the institution, reinforcing the function of medical correspondents in antibiotic therapy and infectiologists, periodic evaluation of antibiotic therapy, should improve the quality of antibiotic therapy.

Relationship between antibiotic consumption and antibiotic policy: an adjusted analysis in the French healthcare system

OBJECTIVES

In France, the public reporting of antibiotic policies in hospitals has been mandatory since 2007. Consequently, all hospitals provide to the Ministry of Health an annual follow-up of antibiotic policy. This study aimed at identifying antibiotic policy measures related to a lower antibiotic consumption.

METHODS

Data on antibiotic policy were extracted from the 2007 infection control indicator database in 977 acute hospitals providing antibiotic consumption data expressed in defined daily doses per 1000 patient-days (84% of all acute French hospitals). Policy data were collected using a standardized questionnaire including nine measures. From these measures, a composite score of 20 points and three policy sub-scores (organization, resource and action) were defined. Logistic regression analyses were performed using antibiotic consumption as dependent variables. Antibiotic consumption was categorized as low (≤ 75th percentile) or high (>75th percentile). All models were adjusted for hospital characteristics.

RESULTS

Hospitals had an average score of 13.8 out of 20 points.The least common antibiotic policy measures were information technology support such as a computerized link between pharmacy, laboratory and wards (39%) and information technology support for prescription (33%). Multivariable analysis showed that a high resource score was significantly associated with lower antibiotic consumption. Among measures included in the resource score, information technology support for prescription was significantly associated with lower antibiotic consumption. The odds ratio was 0.55 (95% confidence interval 0.39-0.78).

CONCLUSIONS

Information technology support for prescription could play an important role in controlling antibiotic consumption. Further investigations should study the type of computerized prescription system to implement in hospitals.

Antibiotic stewardship programmes: legal framework and structure and process indicator in Southwestern French hospitals, 2005-2008

French hospitals are required to implement antibiotic stewardship programmes (ABS) to improve antibiotic use. We analysed the legal framework on ABS and assessed its impact on hospitals' ABS development in Southwestern France. For each official text, required measures, date of issue, means of control and incentives were analysed. Annual retrospective surveys were conducted in 84 hospitals from 2005 to 2008 to monitor implementation of ABS components: organisation, resources and actions. Evolution of individual measures and of a structure and process indicator (SPI) reflecting ABS was described for each hospital. From 2002, official texts issued by health authorities set out requirements on ABS, based on previous professional guidelines. Incentives and means of control were reinforced in 2006 and in 2007 with mandatory reporting of SPI for public disclosure. ABS implementation improved during the course of the study period. In 2008, at least 98% of hospitals had implemented formularies, antibiotic committees, surgical prophylaxis guidelines, and monitored antibiotic use; antibiotic advisors were appointed in 85% of hospitals. Little progress was made regarding time dedicated by pharmacists to antibiotic management and restrictive dispensation using stop-orders. Computerised tools, continuing education and audits remained under-used. SPI values were higher in private hospitals and rehabilitation centres than in others. Official texts and the SPI public disclosure increased professionals' and hospital managers' commitment to develop ABS, resulting in improvements. However, some actions still need to be reinforced. It appears crucial to monitor practical implementation to better approach ABS effectiveness and to adapt requirements.

Relation entre politique de bon usage et consommation des antibiotiques dans les établissements de santé

OBJECTIVE

The authors had for aim to study the relationship between antibiotic policies and antibiotic consumption in hospitals.

DESIGN

A component analysis was used to summarize the various measures of the antibiotic policies developed by hospitals. Antibiotics consumption was expressed as a number of Daily Defined Doses per 1,000 patient-days. The relation was studied by a multiple linear regression model with adjustment on hospital activity.

RESULTS

The first component illustrated an active program of antibiotic policies associating: a local antibiotic committee, an infectious diseases consultant, written local guidelines for prescriptions and restrictive measures before dispensing. The highest antibiotic consumption was associated with active policies, especially for carbapenems, glycopeptides, and aminoglycosides. However the relationship differed according to the type of hospital, with lower antibiotic consumption, especially for penicillins, in private hospitals that had more active policies.

CONCLUSION

The difference between public and private hospitals could be explained by the type of institution but also by the unit used to measure antibiotic consumption.
