Does prescribing antibiotics affect patient satisfaction?

The results are mixed as to whether prescribing antibiotics affects patient satisfaction. Two studies in the early 2000s found that both patients and parents reported higher satisfaction with physicians who explained why antibiotics were not indicated vs physicians who simply prescribed them, and that such explanations do not need to take a lot of time.37,38 (See TABLE 39,37,38 for patient care tips.)

A more recent study found that higher antibiotic prescribing practices in Britain were associated with modestly higher patient satisfaction ratings.39 The authors of this study noted, however, that reduced antibiotic prescribing may be a proxy for other practice patterns that affected satisfaction ratings.

Reducing antibiotic prescribing reduces resistance

There is also strong evidence that when physicians decrease antibiotic prescribing, antimicrobial resistance follows suit. One of the earlier landmark studies to demonstrate this was a Finnish study published in 1997.40 The authors found that a reduction of macrolide antibiotic consumption in Finland led to a reduction in streptococci macrolide resistance from 16.5% to 8.6%.40

There is strong evidence that when physicians decrease antibiotic prescribing, antimicrobial resistance follows suit.

Since then, multiple studies have demonstrated similar results for both respiratory and urinary tract infections.41,42 A 2017 meta-analysis analyzing 32 studies found that antibiotic stewardship programs reduced the incidence of infections and colonization with multidrug-resistant Gram-negative bacteria (51% reduction), extended-spectrum beta-lactamase–producing Gram-negative bacteria (48%), and methicillin-resistant Staphylococcus aureus (37%). There was also a reduction in the incidence of C. difficile infections (32%).43
