OBJECTIVES: Many states have implemented prescription drug monitoring programs (PDMPs) to address abuse and diversion of controlled substances. While the perceptions of prescribers and dispensers have been examined, the patient perspective on PDMPs is notably absent from existing research. This project examined patient perceptions of Kentucky’s PDMP by asking Medicaid beneficiaries about their experiences with the Kentucky All Schedule Prescription Electronic Reporting program (KASPER). METHODS: Medicaid beneficiaries over age 18 were contacted by mail to complete a modified version of the Consumer Assessment of Health Plans Survey. A reminder postcard and second survey was sent to non-responders two weeks after the first mailing. 1,305 surveys were returned (n=5,297, response rate=24.64%). Responses were coded and 25% of surveys were re-coded to test inter-coder reliability. Statistical analysis was conducted in STATA v11.0. RESULTS: Of 461 respondents, 63 (13.67%) reported that their health care provider had discussed their KASPER report with them. Fewer respondents reported that KASPER prevented them from getting (8.11%) or filling (8.53%) a prescription. Patients with chronic pain conditions were more likely to have a health care provider discuss a KASPER report with them (10.18%) than non-chronic pain patients (3.95%). Chronic pain patients were also more likely to report that a KASPER report prevented them from getting a prescription than non-chronic pain patients (6.01% vs. 1.75%). Chi-square testing demonstrates that these differences are statistically significant (discussed KASPER report p=0.006; KASPER report prevented getting prescription p=0.013). There were limited differences in patient-reported experiences with KASPER based upon patient gender, race, Hispanic ethnicity, or education level.    CONCLUSIONS: Most respondents report they are unaffected by the KASPER program. Respondents with chronic pain are significantly more apt to report difficulty getting and filling prescriptions. States seeking to form or alter PDMPs should consider patient input as well as prescriber and dispenser opinions.
