ABSTRACT
OBJECTIVE: To determine the degree in variation of oral liquid pediatric compounding practices in Michigan pharmacies. DESIGN: Cross-sectional survey study. SETTING: All types of inpatient and outpatient pharmacies across the state of Michigan, excluding nuclear pharmacies and long-term care facilities. PARTICIPANTS: 244 Michigan pharmacies. INTERVENTION: An online survey tool was used to assess the current compounding practices of 147 oral liquid pediatric medications. The survey was e-mailed or faxed to hospitals, chain pharmacies, and independent pharmacies. Pharmacists were also mailed a follow-up postcard, and the Michigan Pharmacists Association publicized the project through its journal and annual meeting. MAIN OUTCOME MEASURES: Pharmacy demographics; number of compounding pharmacies; number of medications compounded; awareness of compounding errors; results of compounding errors; and number of concentrations compounded per medication. RESULTS: The majority of respondents were from outpatient pharmacies, but inpatient and other types of pharmacies were also represented. The majority of participating pharmacies compound fewer than five oral liquid medications per week. Awareness of errors was low overall, with no errors believed to result in permanent harm or death. The number of concentrations compounded per medication ranged from 1 to 9, with the majority of pharmacies compounding more than 3 concentrations per medication. CONCLUSION: There is a considerable degree of variation in current oral pediatric liquid compounding practices in Michigan pharmacies. This variability poses a significant risk to patient safety.
