Objectives:

The purpose of this study was to describe the rate of medication short-term supply dispensings (tider), patient and medication characteristics associated with a tider, and costs for tider dispensings in an integrated healthcare delivery system in Colorado, United States.

Methods:

This was a retrospective study conducted in an integrated healthcare delivery system’s outpatient clinics. All patients who had a prescription dispensed for a study medication at any of the system’s 28 outpatient pharmacies during the first quarter of 2016 were included. A tider was identified as a 3-day supply of a prescription medication that was dispensed at no charge to a patient. The quarterly tider rate and the per member per month (PMPM) cost of tiders were estimated. Patient and medication characteristics associated with a tider were assessed.

Results:

A total of 444,225 study medications were dispensed for 135,907 patients during the study period. There were 3,430 (0.77%, 95%CI 0.75%:0.80%) medications dispensed as a tider. The PMPM cost of tider medications and their dispensing fees was USD 0.03. There were 1,092 (0.8%) and 134,815 (99.2%) patients who did and did not, respectively, have at least one tider dispensed during the study period. Patient characteristics strongly associated with having had a tider dispensed included being older, male, and a Medicare beneficiary. Cardiovascular and neuromuscular medications had the highest rates of tider dispensing.

Conclusions:

The rate of tider dispensing was relatively low; however, approximately one out of 125 patients had at least one tider. Patients who had a tider were more likely to be older, female, a Medicare beneficiary, and having had a previous tider dispensing and a higher burden of chronic disease. The tider medication was more likely to be a cardiovascular or neuromuscular medication class and more likely to be dispensed on a weekend. The total cost of dispensing a tider appears reasonable since the benefits of providing patients with needed medications likely outweigh the cost. Future studies should be performed to assess the impact of tider dispensing on health outcomes.
