Do prescription monitoring programs impact state trends in opioid abuse/misuse?

OBJECTIVE: Prescription monitoring programs (PMPs) are statewide databases containing prescriber and patient-level prescription data on select drugs of abuse. These databases are used by medical professionals or law enforcement officials to identify patients with prescription drug use patterns indicative of abuse or providers engaging in illegal activities. Most states have implemented PMPs in an attempt to curb prescription drug abuse and diversion. However, assessment of their impact on drug abuse is only beginning. This study aimed to evaluate the relationship between PMPs and opioid misuse over time in two drug abuse surveillance data sources. METHODS: Data from the RADARS® System Poison Center and Opioid Treatment surveillance databases were used to obtain measures of abuse and misuse of opioids. Repeated measures negative binomial regression was applied to quarterly surveillance data (from 2003 to mid-2009) to estimate and compare opioid abuse and misuse trends. PMP presence was modeled as a time varying covariate for each state. RESULTS: Results support an association between PMPs and mitigated opioid abuse and misuse trends. Without a PMP in place, Poison Center intentional exposures increased, on average, 1.9% per quarter, whereas opioid intentional exposures increase 0.2% (P = 0.036) per quarter with a PMP in place. Opioid treatment admissions increase, on average, 4.9% per quarter in states without a PMP vs 2.6% (P = 0.058) in states with a PMP. In addition to the time trend, population and a measure of drug availability were also significant predictors. A secondary analysis that classified PMP based upon ideal characteristic showed consistent though not significant results. CONCLUSIONS: Two observational data sources offer preliminary support that PMPs are effective. Future efforts should evaluate what PMP characteristics are most effective and which opioids are most impacted.

A statewide prescription monitoring program affects emergency department prescribing behaviors.

STUDY OBJECTIVE: Ohio recently instituted an online prescription monitoring program, the Ohio Automated Rx Reporting System (OARRS), to monitor controlled substance prescriptions within Ohio. This study is undertaken to identify the influence of OARRS data on clinical management of emergency department (ED) patients with painful conditions. METHODS: This prospective quasiexperimental study was conducted at the University of Toledo Medical Center Emergency Department during June to July 2008. Eligible participants included ED patients with painful conditions. Patients with acute injuries were excluded. After clinical evaluation, and again after presentation of OARRS data, providers answered a set of questions about anticipated pain prescription for the patient. Outcome measures included changes in opioid prescription and other potential factors that influenced opioid prescription. RESULTS: Among 179 participants, OARRS data revealed high numbers of narcotics prescriptions filled in the most recent 12 months (median 7; range 0 to 128). Numerous providers prescribed narcotics for patients (median 3 per patient; range 0 to 40). Patients had filled narcotics prescriptions at different pharmacies (mean [SD] 3.5 [4.4]). Eighteen providers are represented in the study. Four providers treated 63% (N=114) of the patients in the study. After review of the OARRS data, providers changed the clinical management in 41% (N=74) of cases. In cases of altered management, the majority (61%; N=45) resulted in fewer or no opioid medications prescribed than originally planned, whereas 39% (N=29) resulted in more opioid medication than previously planned. CONCLUSION: The use of data from a statewide narcotic registry frequently altered prescribing behavior for management of ED patients with complaints of nontraumatic pain.

Is the Kentucky prescription reporting system useful in the care of hospitalized patients?

Patients who are physically dependent on prescription drugs often create clinical management problems during hospitalization. Identifying those patients who have prescription drug problems can be difficult at the time of admission, but the information of the Kentucky All Schedule Prescription Electronic Reporting (KASPER) system can be useful clinically. The purpose of this study was to examine the value of the KASPER system in the management of patients admitted to an acute care hospital. A convenience sample of 58 hospitalized patients was evaluated. The patients' clinical and demographic data were abstracted from the medical record. The KASPER data were used to confirm the patients' history of drug use. In this sample, the KASPER data supplied additional, clinically useful information that was not available from the clinical history or screening toxicology from 30 (51.7%) of these patients. We conclude that the KASPER system has the potential to assist physicians in the care of hospitalized patients who take controlled drugs that are obtained by physician prescription and filled in Kentucky pharmacies.
