The financial burden is also substantial: antibiotic-resistant infections cost $20 billion in excess direct health care expenses and as much as $35 billion in lost productivity from hospitalizations and sick days.
However, several studies report biofilm persistence despite substantial antibiotic diffusion (e.g. [ 13, 14], reviewed in [ 1, 15]).
Our model estimated that 912,036 antibiotic prescriptions were attributable to RSV-respiratory disease in an average season, suggesting substantial inappropriate antibiotic prescribing.
[34] highlighted extensive variations in antibiotic prescribing, with substantial overprescription of antibiotics for common childhood illnesses.
Studies focusing on antibiotic resistance for Streptococcus have indicated that in general the viridans group shows substantial resistance to antibiotics (in particular beta-lactam antimicrobials) (Facklam 2002).
This corresponds to an incidence rate reduction of 66.5%95%5% confidence interval 58.8% to 74.4%; P<0.001), showing a substantial reduction of antibiotics use. Figure 2 shows the distribution of the individual number of courses of antibiotics by randomisation group.
Two recent trials found a more substantial effect of antibiotics when they looked at treatment failure as the outcome.
Results of cefoxitin (2nd generation), ceftriaxone, and cefexime (3rd generation) showed that the percentages of S. lugdunensis resistant isolates were substantial to these antibiotics: 46.6%, 53.3%, and 40%, respectively.
If it could be shown that this strategy allows for a substantial reduction of antibiotics while being symptomatically effective and safe, treatment recommendations should be changed: anti-inflammatory agents as first choice therapy for uncomplicated UTI, and antibiotic treatment only for those who return with persisting or recurrent symptoms.
A substantial proportion of antibiotic use in this setting is inappropriate.
