Antibiotic prescribing for the older adult: beliefs and practices in primary care.
Older adults suffer high morbidity and mortality following serious infections, and hospital admissions with these conditions are increasingly common. Antibiotic prescribing in the older adult population, especially in long-term care facilities, has been argued to be inappropriately high. In order to develop the evidence base and provide support to GPs in achieving antimicrobial stewardship in older adults it is important to understand their attitudes and beliefs toward antibiotic prescribing in this population. ⋯ Diagnosing serious infections in older adults is challenging and antibiotic prescribing practices reflect this challenge, but also reflect an absence of clear guidance or evidence. Research that can fill the gaps in the evidence base is required in order to support GPs with their critical antimicrobial stewardship role in this population.

Ciprofloxacin in critically ill subjects: considering hepatic function, age and sex to choose the optimal dose.
Pathophysiological changes often result in altered pharmacokinetics of ciprofloxacin in critically ill patients. Although ciprofloxacin clearance (CLCIP) substantially depends on kidney function in healthy volunteers, its relationship to measured creatinine clearance (CLCRM) is weak in critically ill patients. ⋯ Bilirubin, age and sex should be considered to assess the need for dose reductions. For MICs ≤0.25 mg/L, it might be appropriate to reduce the dose to 400 mg/day for elderly female subjects with high bilirubin.
