Highlights |
• | Simplified guidelines are associated with a significant improvement of antibiotic use. |
• | The next step is to simplify reporting of antibiotic susceptibility tests. |
• | Using both tools in three healthcare facilities, we observed a high rate of adequate antibiotic therapies without infectious disease advice. |
Abstract |
Objectives |
We reported the impact of internal guidelines coupled with selective reporting of antibiotic susceptibility tests (srAST) on antibiotic adequacy in healthcare facilities.
Methods |
This prospective study involved clinicians from three clinics with medical and surgical activities employing a full-time infectious disease (ID) specialist. Internal guidelines were updated in 2016. The clinics were working with the same laboratory, which delivered the srAST introduced in March 2017. Two weeks per month over a 6-month period, all isolated bacterial specimens, empirical antibiotic therapies (EAT) and the documented ones were analyzed. An EAT listed in the guidelines and a documented therapy mentioned in the srAST defined their adequacy.
Results |
A total of 257 positive bacterial samples were analyzed in 199 patients, for which 106 infections were studied. Of these, 32% were urinary tract infections, 15% were primary bloodstream infections, 11% were bone infections, and 42% were other types of infection. The three main bacteria were Escherichia coli (27%), Staphylococcus aureus (24%), and Enterococcus faecalis (14%). The total number of antibiotic prescriptions was 168, with 75 (45%) EATs and 93 (55%) documented therapies. There were 35/75 (47%) adequate EATs and 86/93 (92%) adequate documented therapies. The ID specialist was not involved in 90/168 (53.5%) prescriptions, of which 43/90 (48%) were adequate, with 21/35 (60%) EATs and 22/86 (25%) documented therapies. There was a statistical correlation between compliance of the EATs with guidelines and of the documented therapy with srAST (p=0.02).
Conclusion |
Combining internal guidelines and srAST led to a high rate of antibiotic adequacy.
