Prescription drug monitoring programs (PDMPs)
Prescription drug monitoring programs (PDMPs) are electronic databases, housed in state agencies, that track prescribing and dispensing of controlled substances. Most states monitor drugs on Schedules II - IV of the Drug Enforcement Administration’s drug schedule; many also include drugs on Schedule V and other controlled substances. Schedule I drugs (e.g., heroin) are not included. PDMPs can be used by prescribers and pharmacists to view prescriptions written for and dispensed to individual patients, by law enforcement agencies to identify drug diversion or pill mills, or by state medical boards to identify potentially problematic prescribers. Drugs monitored, individuals authorized to use the system, functionality, and use varies from state to state (CDC-PDMPs).

What does the research say about effectiveness? -+
There is some evidence that prescription drug monitoring programs (PDMPs) reduce the amount and number of drugs prescribed, particularly opioids (Fisher 2012a, Rasubala 2015, Simoni-Wastila 2012, Chang 2016, Rutkow 2015a). PDMPs can also reduce opioid overdose deaths (Patrick 2016, Pardo 2017, Delcher 2015, CDC MMWR-Johnson 2014). However, additional evidence is needed to confirm effects.
States with PDMPs appear to have smaller increases in opioid misuse (Reifler 2012) and opioid-related hospital admissions per year than states without PDMPs (Reifler 2012, Reisman 2009). States with PDMPs also appear to slow the increase in supply of prescription pain relievers and stimulants (Reisman 2009, Simeone 2006). Opioid death rates are lower in states with more robust PDMPs than states with weaker PDMPs (Pardo 2017).
An assessment of New York’s mandatory PDMP indicates that 78% fewer opioid pills were prescribed in a dental urgent care center during the 3-months after implementation (Rasubala 2015). Combined with other efforts to regulate prescribing and dispensing, Florida’s PDMP has been shown to reduce the number of opioid prescriptions among high-volume prescribers (Chang 2016, Rutkow 2015a) and reduce diversion of prescription opioids (Surratt 2014). An Indiana-based assessment of PDMPs in pharmacy practice indicates that pharmacists who always use a PDMP are more likely to refuse to dispense opioids than pharmacists who never do (Norwood 2016a).
Physicians who use PDMPs during patient visits in Emergency Departments (EDs) appear to alter prescribing decisions, decreasing or eliminating opioids with indications of drug seeking behavior and increasing them when there are no indications of such behavior (Weiner 2013, Baehren 2010). ED providers also report feeling more comfortable prescribing controlled substances when they receive information from PDMPs (McAllister 2015). PDMPs may help confirm physician suspicion of prescription drug misuse (Sowa 2014). Providers who identify suspicious medication behavior can respond clinically, making referrals to mental health or substance abuse treatment (Green 2012, Irvine 2014), and, overall, appear unlikely to pursue legal interventions (Green 2012).
PDMPs can reduce doctor shopping among patients (Pradel 2009, CDC Vital Signs-Opioids). One year after New York and Tennessee required providers to use PDMPs before prescribing painkillers, for example, there were large decreases in the percentage of patients seeing multiple providers to obtain the same drug (CDC Vital Signs-Opioids).
Prescribers are more likely to use PDMPs that present data in real time, are used by all prescribers, and actively identify potential problems such as multiple prescribers or multiple prescriptions (CDC Vital Signs-Opioids). Researchers recommend that PDMPs also be easy to access and use, accessible across states, open to all prescribers to register, include mandatory pharmacy reporting and regular evaluation, and require use in EDs. Systems should contain standardized content and monitor prescription of all drugs in Drug Enforcement Administration (DEA) Schedules II to V, as well as other drugs of concern (CDC-Promising PDMP, Perrone 2012, Greenwood-Ericksen 2016).
Implementation Examples -+
As of June 2020, 49 states and Washington, D.C. have legislation supporting operational prescription drug monitoring programs (PDMPs); Missouri has not enacted legislation (PDMP TTAC). As of July 2019, 43 states and Washington, D.C. require prescribers to register with the PDMP and 45 states mandate reviewing it in specified circumstances (PDMP TTAC).
PDMPs are most often administered by boards of pharmacy, departments of health, law enforcement, and professional licensing (PDMP TTAC). Common methods for funding PDMPs include federal grants such as the Harold Rogers Prescription Drug Monitoring Program, private/non-federal grants, state general revenue funds, controlled substances registration fees, professional licensing fees, and health insurers’ fees (BJA-PDMP grant, CRS-PDMP 2018).
Many states allow access to PDMP data across state lines using the National Association of Boards of Pharmacy’s PMP InterConnect (AHRQ HCIE-Catizone). As of July 2019, 47 states and Washington, D.C. share data with authorized users in other states (PDMP TTAC).
