^∗ Chi-square test comparing drug categories in intervention and control periods.

^† Drug category (medications included): ACEI (ramipril, perindropril, captopril, lisinopril); B-adrenergic blocking agents (acebutolol, atenolol, bisoprolol, sotalol); antibiotics (ciprofloxacin, erythromycin, gentamicin, vancomycin, levofloxacin, sulfamethoxazole-timethropim, amikacin, teicoplanin, tobramycin, norfloxacin, and fosfomycin); antigout drug (colchicine, allopurinol); digoxin; antidiabetes drug (metformin).

^‡ Values are expressed as number (percentage of total prescriptions needing dosage adjustment).

ACEI = angiotensin-converting enzyme inhibitor; eGFR = estimated glomerular filtration rate.
