RT Journal A1 Kripalani S T1 PRior experience with universal medication schedules in 4 controlled trials JF Archives of Internal Medicine JO Archives of Internal Medicine YR 2011 FD September 12 VO 171 IS 16 SP 1510 OP 1511 DO 10.1001/archinternmed.2011.381 UL http://dx.doi.org/10.1001/archinternmed.2011.381 AB I read with interest the recent article by Wolf and colleagues about the variability with which patients self-dose a complex drug regimen.1 In this article, the authors discuss the Universal Medication Schedule (UMS), proposed in an Institute of Medicine report as a means to simplify complex drug regimens into 4 standard times of administration—morning, noon, evening, and bedtime.2 While awaiting the results of Wolf and colleagues' ongoing work to evaluate the UMS, I write to share the experience of my research group with medication instructions presented in this manner.
