Use Of Prescription Drug Monitoring Programs Research Articles

State-level factors associated with implementation of prescription drug monitoring program integration and mandatory use policies, United States, 2009-2020.

Prescription drug monitoring programs (PDMPs) have been widely adopted as a tool to address the prescription opioid epidemic in the United States. PDMP integration and mandatory use policies are 2 approaches states have implemented to increase use of PDMPs by prescribers. While the effectiveness of these approaches is mixed, it is unclear what factors motivated states to implement them. This study examines whether opioid dispensing, adverse health outcomes, or other non-health-related factors motivated implementation of these PDMP approaches. Time-to-event analysis was performed using lagged state-year covariates to reflect values from the year prior. Extended Cox regression estimated the association of states' rates of opioid dispensing, prescription opioid overdose deaths, and neonatal opioid withdrawal syndrome with implementation of PDMP integration and mandatory use policies from 2009 to 2020, controlling for demographic and economic factors, state government and political factors, and prior opioid policies. In our main model, prior opioid dispensing (HR 2.31, 95% CI 1.17, 4.57), neonatal opioid withdrawal syndrome hospitalizations (HR 1.55, 95% CI 1.09, 2.19), and number of prior opioid policies (HR 2.13, 95% CI 1.13, 4.00) were associated with mandatory use policies. Prior prescription opioid overdose deaths (HR 1.21, 95% CI 1.08, 1.35) were also associated with mandatory use policies in a model that did not include opioid dispensing or neonatal opioid withdrawal syndrome. No study variables were associated with implementation of PDMP integration. Understanding state-level factors associated with implementing PDMP approaches can provide insights into factors that motivate the adoption of future public health interventions.

Association Between Prescription Drug Monitoring Program Use Mandate and Opioid Prescribing and Patient-Reported Outcomes After Surgery.

To evaluate changes in opioid prescribing and patient-reported outcomes after surgery following implementation of Michigan's prescription drug monitoring program (PDMP) use mandate in June 2018. Most states mandate clinicians to query prescription drug monitoring program (PDMP) databases before prescribing controlled substances. Whether these PDMP use mandates affect opioid prescribing and patient-reported outcomes after surgery is unclear, especially among patients with elevated "Narx" scores, a risk score for overdose death used in most PDMPs. We conducted an interrupted time series analysis of a statewide surgical registry linked to Michigan's PDMP database. Analyses included adults undergoing general surgical procedures during January 2017-October 2019. Outcomes included monthly mean days supplied in dispensed opioid prescriptions (those filled within 3 days of discharge) and monthly mean scores for 3 patient-reported outcomes (pain in the week after surgery, care satisfaction, regret undergoing surgery). Segmented regression models were used to assess for level and slope changes in outcomes in June 2018. Analyses were repeated among patients with Narx scores ≥200, a threshold that defines the top quartile. Analyses included 21,897 patients. The mandate was associated with a -0.5 (95% CI: -0.8, -0.2) level decrease in mean days supplied in dispensed opioid prescriptions, but not with worsened patient-reported outcomes. Findings were similar among patients with Narx scores ≥200. Following implementation of Michigan's PDMP use mandate, the duration of opioid prescriptions decreased, but patient-reported outcomes did not worsen. Findings suggest PDMP use mandates may not be associated with worsened experience among general surgical patients.

Helpful, Unnecessary, or Harmful: A Systematic Review of the Effects of Prescription Drug Monitoring Program Use on Opioid Prescriptions

Prescription drug misuse is a global problem, especially in the United States (US). Clinician involvement is necessary in this crisis, and prescription drug monitoring programs (PDMPs) are a recommended tool for the prevention, recognition, and management of prescription opioid misuse. However, because of the plethora of differences between different PDMPs, research on their effects is mixed. Yet, despite varied evidence, policy on PDMP use is trending stricter and more comprehensive. We aimed to identify patterns in the research to inform clinicians and policy. Through a systematic review of four literature databases (CINAHL, Cochrane Database, Embase, and Medline/OVID), we found 56 experimental and quasi-experimental studies published between 2016 and 2023 evaluating PDMP effects on clinician behavior. To address study heterogeneity, we categorized studies by type of intervention and study outcome. The review suggests that more comprehensive PDMP legislation is associated with decreases in the number of opioid prescriptions overall and the number of risky prescriptions prescribed or dispensed. However, this review shows that much is still unknown, encourages improvements to PDMPs and policies, and suggests further research.

Prescription drug monitoring program use by opioid prescribers: a cross-sectional study.

Clinician use of prescription drug monitoring programs (PDMPs) has been linked to better patient outcomes, but state requirements to use PDMPs are unevenly enforced. We assessed PDMP use in Minnesota, which requires opioid prescribers to hold accounts and, in most cases, search the PDMP before prescribing, but where enforcement authority is limited. Using 2023 PDMP data, we found that 4 in 10 opioid prescribers did not search and 2 in 10 did not hold an account. PDMP use was strongly associated with prescribing volume, but even among the top decile of opioid prescribers, 8% never searched the PDMP. Thirty-two percent of opioid fills came from clinicians who did not search the PDMP. Failures to use the PDMP may be driven by a lack of information about state requirements, beliefs that these requirements are not enforced, and the costs of accessing the PDMP relative to the benefits. These results highlight the potential for policy makers to promote safer and better-informed prescribing of opioids and other drugs by addressing the forces that have limited PDMP use so far.

Implementation of Electronic Health Record Integration and Clinical Decision Support to Improve Emergency Department Prescription Drug Monitoring Program Use

To evaluate the implementation of 3 electronic health record (EHR)-based interventions to increase prescription drug monitoring program (PDMP) use in the emergency department (ED): EHR-PDMP integration, addition of a PDMP risk score, and addition of EHR-based clinical decision support alert to review the PDMP when prescribing an opioid. Three intervention stages were implemented using a prospective stepped-wedge design at 5 university-affiliated EDs split into 3 practice groups. The PDMP use and prescribing rates during the 3 stages were compared with baseline before EHR integration and a sustainability stage where the clinical decision support alert was removed, but EHR integration and risk score remained. Generalized linear mixed model with logit link function and a random intercept for clinicians was analyzed. The ED provider PDMP review before opioid prescribing was low in all stages. The highest review rate occurred during interruptive clinical decision support alerts, 23.8% (interquartile range 10.6 to 37.5). Overall, opioid prescribing declined, and PDMP review was not associated with a decrease in opioid prescribing. PDMP review was associated with a reduction in the probability of prescribing an opioid as the number of prior opioid prescriptions increased (odds ratio: 0.92 [95% confidence interval: 0.91 to 0.94] for every additional prescription). The EHR-PDMP integration did not increase PDMP use in the ED, but a PDMP risk score and a clinical decision support alert were associated with modest increases in the probability of PDMP review. When the PDMP is reviewed, ED clinicians are less likely to prescribe opioids to patients with a high number of prior opioid prescriptions.

Tracking changes in opioid prescriptions dispensed following the enactment of a prescription drug monitoring program use mandate

BackgroundPrescription drug monitoring programs (PDMPs) are state-based surveillance tools used to track controlled substances dispensed to patients and identify patients at-risk of misuse. Starting April 2017, Wisconsin required all prescribers access PDMP to review patient information before issuing a controlled substance prescription order for more than a 3-day supply. A primary goal of PDMP use mandates is to reduce avoidable prescribing and mitigate opioid related mortality and morbidity. Current literature has not evaluated the existence of a time point post-policy implementation, at which the trend in opioid dispensing changes, reflecting normalization/maintenance of opioid prescribing. ObjectiveWe sought to evaluate the impact of the PDMP use mandate on trends in opioid prescriptions dispensed and test a hypothesis that a change or inflection in opioid prescriptions dispensed occurred post-mandate implementation. MethodsInterrupted Time Series Analysis (ITSA) design was used to examine whether the level (immediate impact) and trend in opioid prescribing changed significantly after the PDMP use mandate was implemented. We used a novel Change Point Analysis (CPA) approach to test the hypothesis i.e., identify if and when a change or inflection in opioid dispensing trend occurred after implementation of the PDMP use mandate. ResultsITSA model results showed a significant drop in opioid prescriptions dispensed (p < 0.05) immediately after the mandate implementation (i.e., April 2017). Results of the CPA identified a significant inflection in opioid prescriptions dispensed starting January 2019 (21-months post-policy implementation). An ITSA model using the inflection point as an interruption showed that the trend in opioid prescriptions dispensed became flatter after the inflection point, suggesting normalization. ConclusionUsing a novel CPA approach, the findings showed an inflection in the trend in opioid prescriptions dispensed post-PDMP use mandate implementation, implying that most of the avoidable prescribing likely was curtailed. The results suggest that the patient information presumably accessed from the WI PDMP interface was useful in helping prescribers to make an informed clinical decision about opioid prescribing.

Barriers to Increasing Prescription Drug Monitoring Program Use: A Multidisciplinary Perspective.

Prescription drug monitoring programs are implemented through individual state policies and are one solution to curb the opioid crisis. The objectives of this study are to: (1) describe the multidisciplinary experiences using this program in practice; (2) identify limitations of the program and the desired features for improvement; and (3) characterize expectations for improved access when prescription drug monitoring programs are embedded in the electronic health record. A qualitative descriptive study design used semistructured interviews of 15 multidisciplinary healthcare providers. Textual data were analyzed using content analysis. Results showed the prescription drug monitoring program was helpful to decision-making processes related to opioid prescribing and referral to treatment; there were barriers limiting healthcare providers' use of the prescription drug monitoring program; preferences were delineated for integrating prescription drug monitoring program into electronic health record; and recommendations were provided to improve the program and increase use. In conclusion, the prescription drug monitoring program was viewed as useful in making strides to reduce the impact of inappropriate opioid prescribing in our country. By engaging a multidisciplinary group of healthcare providers, solutions were offered to improve the interface and function of the prescription drug monitoring program to assist in increasing use.

Prescription drug monitoring programs use mandates and prescription stimulant and depressant quantities

BackgroundWhile the mandate to check patients’ prescription history in Prescription Drug Monitoring Program (PDMP) database before prescribing/dispensing controlled drugs has been shown to be an important tool to curb opioid abuse, less is known about whether the mandate can reduce the misuse of other commonly abused prescription drugs. We examined whether PDMP use mandates were associated with changes in prescription stimulant and depressant quantities.MethodsUsing data from Automated Reports and Consolidate Ordering System (ARCOS), we employed difference-in-differences design to estimate the association between PDMP use mandates and prescription stimulant and depressant quantities in 50 U.S. states and the District of Columbia from 2006 to 2020. Limited PDMP use mandate was specific only to opioids or benzodiazepines. Expansive PDMP use mandate was non-specific to opioid or benzodiazepine and required prescribers/dispensers to check PDMP when prescribing/dispensing targeted controlled substances in Schedule II-V. The main outcomes were population-adjusted prescription stimulant (amphetamine, methylphenidate, lisdexamfetamine) and depressant (amobarbital, butalbital, pentobarbital, secobarbital) quantities in grams.ResultsThere was no evidence that limited PDMP use mandate was associated with a reduction in the prescription stimulant and depressant quantities. However, expansive PDMP use mandate that was non-specific to opioid or benzodiazepine and required prescribers/dispensers to check PDMP when prescribing/dispensing targeted controlled substances in Schedule II-V was associated with 6.2% (95% CI: -10.06%, -2.08%) decline in prescription amphetamine quantity.ConclusionExpansive PDMP use mandate was associated with a decline in prescription amphetamine quantity. Limited PDMP use mandate did not appear to change prescription stimulant and depressant quantities.

Targeted messaging to improve the adoption of clinical decision support for prescription drug monitoring program use.

Clinical decision support (CDS) can prevent medical errors and improve patient outcomes. Electronic health record (EHR)-based CDS, designed to facilitate prescription drug monitoring program (PDMP) review, has reduced inappropriate opioid prescribing. However, the pooled effectiveness of CDS has exhibited substantial heterogeneity and current literature does not adequately detail why certain CDS are more successful than others. Clinicians regularly override CDS, limiting its impact. No studies recommend how to help nonadopters recognize and recover from CDS misuse. We hypothesized that a targeted educational intervention would improve CDS adoption and effectiveness for nonadopters. Over 10 months, we identified 478 providers consistently overriding CDS (nonadopters) and sent each up to 3 educational message(s) via email or EHR-based chat. One hundred sixty-one (34%) nonadopters stopped consistently overriding CDS and started reviewing the PDMP after contact. We concluded that targeted messaging is a low-resource way to disseminate CDS education and improve CDS adoption and best practice delivery.

Health-care practitioner use of prescription drug monitoring programs in clinical practice in Australia: A qualitative study.

Prescription drug monitoring programs (PDMP) are electronic databases used by prescribers and pharmacists to monitor the use of high-risk prescription medications subject to extramedical use. This study aimed to explore how Australian pharmacists and prescribers are using PDMPs in practice and to gain an understanding of barriers to tool use, as well as practitioner recommendations to increase tool usability and uptake. Semi-structured interviews were conducted with pharmacists and prescribers who use a PDMP (n = 21). The interviews were audio-recorded, transcribed and thematically analysed. The four themes that emerged were: (i) PDMP notifications combined with practitioner clinical judgement guide PDMP usability; (ii) practitioners use PDMPs to facilitate patient and practitioner communication; (iii) workflow systems integration impacts tool usability; and (iv) optimising PDMP information and data access including practitioner-tool engagement to improve tool uptake and usability. Practitioners appreciate the value of PDMP information support for clinical decisions and patient communication. However, they also acknowledge the challenges to tool use and recommend improvements including enhanced workflow, systems integration, optimisation of tool information and national data sharing. Practitioners provide an important perspective on PDMP use in clinical practice. The findings can be drawn on by PDMP administrators to improve tool usefulness. Consequently, this may lead to an increase in practitioner PDMP use and optimise the delivery of quality patient care.

Associations of clinical personnel characteristics and controlled substance prescribing practices.

Over 68,000 deaths were attributed to opioid-related overdose in 2020. Evaluative studies have shown that states that utilized Prescription Drug Monitoring Program (PDMP) systems have decreased opioid-related deaths. With the growing use of PDMPs and an ongoing opioid epidemic, determining the demographics of physicians at risk of overprescribing can elucidate prescribing practices and inform recommendations to change prescribing behaviors. This study aims to assess prescribing behaviors by physicians in 2021 based on four demographics utilizing the National Electronic Health Record System (NEHRS): physician's age, sex, specialty, and degree (MD or Doctor of Osteopathic Medicine [DO]). We performed a cross-sectional study of the 2021 NEHRS to determine the relationship between physician characteristics and PDMP use on opioid-prescribing behaviors. Differences between groups were measured via design-based chi-square tests. We constructed multivariable logistic regression models to assess the relationships, via adjusted odds ratios (AOR), between physician characteristics and alternate prescribing patterns. Compared to female physicians, male physicians were more likely to alter their original prescription to reduce morphine milligram equivalents (MMWs) prescribed for a patient (AOR: 1.60; CI: 1.06-2.39; p=0.02), to change to a nonopioid/nonpharmacologic option (AOR: 1.91; 95 % CI: 1.28-2.86; p=0.002), to prescribe naloxone (AOR=2.06; p=0.039), or to refer for additional treatment (AOR=2.07; CI: 1.36-3.16; p<0.001). Compared to younger physicians, those over the age of 50 were less likely to change their prescription to a nonopioid/nonpharmacologic option (AOR=0.63; CI: 0.44-0.90; p=0.01) or prescribe naloxone (AOR=0.56, CI: 0.33-0.92; p=0.02). Our results showed a statistically significant difference between specialty category and frequency of prescribing controlled substances. After checking the PDMP, male physicians were more likely to alter their original prescription to include harm-reduction strategies. Optimizing the use of PDMP systems may serve to improve prescribing among US physicians.

The difficulty of using prescription drug monitoring program among office-based physicians in the USA: a challenge to mitigate controlled substance prescriptions

Abstract Objectives To address the usability challenge of Prescription Drug Monitoring Program (PDMP) among office-based physicians in the USA imposed by the difficulty barrier for the system usage, we sought: (1) to estimate the association between the PDMP difficulty of use and reducing or eliminating controlled substance prescriptions; and (2) to test the mediating effect of the frequency of PDMP check in the association between the PDMP difficulty of use and the reduction of controlled substance prescriptions. Methods We conducted a cross-sectional study using nationally representative data from the 2019 National Electronic Health Records Survey with a weighted sample of 214 889 office-based physicians. Weighted bivariate chi-square tests and multivariate logistic regressions with a confidence interval of 95% were performed. Bootstrap technique was used to conduct the causal mediation analysis. Key findings A PDMP that is easier to use was significantly associated with a higher reduction or elimination of controlled substance prescriptions (OR = 1.68; 95% CI: 1.01, 2.77). Easier PDMP use was also significantly associated with more frequent PDMP check prior to prescribing a controlled substance to a patient for the first time (OR = 6.39; 95% CI: 3.36, 12.15). About third (29.79%) of the observed association between PDMP difficulty of use and reducing or eliminating controlled substance prescriptions was mediated through the frequency of PDMP check. Conclusion The difficulty of PDMP limits the system’s usability which undermines the process of mitigating controlled substance prescriptions. Future efforts are needed to re-assess and regulate facilitators for difficult PDMP usage to maximise the success of this system and reach the goals behind its implementation.

The association between prescription drug monitoring programs and controlled substance prescribing: a cross-sectional study using data from 2019 National Electronic Health Records Survey.

The use of controlled medications such as opioids, stimulants, anabolic steroids, depressants, and hallucinogens has led to an increase in addiction, overdose, and death. Given the high attributes of abuse and dependency, prescription drug monitoring programs (PDMPs) were introduced in the United States as a state-level intervention. Using cross-sectional data from the 2019 National Electronic Health Records Survey, we assessed the association between PDMP usage and reduced or eliminated controlled substance prescribing as well as the association between PDMP usage and changing a controlled substance prescription to a nonopioid pharmacologic therapy or nonpharmacologic therapy. We applied survey weights to produce physician-level estimates from the survey sample. Adjusting for physician age, sex, type of medical degree, specialty, and ease of PDMP, we found that physicians who reported "often" PDMP usage had 2.34 times the odds of reducing or eliminating controlled substance prescriptions compared to physicians who reported never using the PDMP (95% confidence interval [CI] 1.12-4.90). Adjusting for physician age, sex, type of doctor, and specialty, we found that physicians who reported "often" use of the PDMP had 3.65 times the odd of changing controlled substance prescriptions to a nonopioid pharmacologic therapy or nonpharmacologic therapy (95% CI: 1.61-8.26). These results support the continued use, investment, and expansion of PDMPs as an effective intervention for reducing controlled substance prescription and changing to nonopioid/pharmacologic therapy. Overall, frequent usage of PDMPs was significantly associated with reducing, eliminating, or changing controlled substance prescription patterns.

Association Between State Opioid Prescribing Limits and Duration of Opioid Prescriptions From Dentists

In part to prevent the harms associated with dental opioid prescriptions, most states have enacted policies limiting the duration of opioid prescriptions for acute pain. Whether these limits are associated with changes in the duration of opioid prescriptions written by dentists is unclear. To evaluate the association between state opioid prescribing limits and the duration of opioid prescriptions from dentists. This difference-in-differences cross-sectional study used data from the IQVIA Longitudinal Prescription Database, an all-payer database reporting prescription dispensing from 92% of retail pharmacies in the US. The sample included opioid prescriptions from dentists dispensed to children aged 0 to 17 years and adults 18 years or older from January 2014 through February 2020. Treatment states were those that implemented limits between January 2016 and December 2018. Control states were those that did not implement limits during the study period. Data on opioid prescribing limits were derived from the Prescription Drug Abuse Policy System. Data were analyzed from January 1 to September 30, 2022. State opioid prescribing limits. The outcome was opioid prescription duration, as measured by days' supply. The association between limits and duration was evaluated using a linear model with a 2-way fixed-effects specification. Covariates included patient characteristics, prescription characteristics, and indicators of implementation of prescription drug monitoring program use mandates. Separate analyses of data from adults and children were conducted owing to differences in the number of treatment states and restrictiveness of limits by age. The adult analysis included 56 607 314 opioid prescriptions for 34 364 775 patients (18 448 788 females [53.7%]; mean [SD] age at the earliest fill, 44.0 [17.4] years) in 22 treatment states and 12 control states. The child analysis included 3 720 837 opioid prescriptions for 3 165 880 patients (1 740 449 females [55.0%]; mean [SD] age at the earliest fill, 14.4 [3.5] years) in 23 treatment states and 12 control states. In both analyses, the median (25th-75th percentile) duration of opioid prescriptions was 3.0 (2-5) days. Implementation of limits, most of which allowed up to a 7-day supply of opioids, was not associated with changes in the duration of opioid prescriptions for adults (mean days' supply: -0.06 days; 95% CI, -0.11 to <0.001 days) or children (mean days' supply: -0.07 days; 95% CI, -0.15 to 0.02 days). In this study of national pharmacy dispensing data, opioid prescribing limits were not associated with changes in the duration of opioid prescriptions from dentists. Future research should investigate the potential role of alternative interventions in reducing opioid prescribing by dentists.

Factors associated with prescription drug monitoring program utilisation: a cross-sectional survey of community pharmacists.

Prescription drug monitoring programs (PDMP) are databases which collect prescribing and dispensing information for high-risk medicines, and are one approach to mitigate prescription opioid-related risks. To examine correlates of PDMP use under voluntary and mandatory conditions, among a representative sample of community pharmacists in Victoria, Australia. An online anonymous survey was conducted and collected data in relation to pharmacist and pharmacy characteristics, comfort in performing certain tasks, PDMP training and the frequency of PDMP use under voluntary and mandatory conditions. Multivariate logistic regression models were performed to determine the effect of each covariate on voluntary and mandatory PDMP use. In total, 265 pharmacists participated (response rate 47%). Under voluntary conditions, a quarter of pharmacists (24.9%) used the PDMP all the time, while half (51.7%) used the PDMP all of the time, once mandated. Pharmacies that stocked naloxone (OR: 1.96; 95% CI 1.11-3.45) and pharmacists that had attended formal PDMP training (OR: 1.78; 95% CI 1.05-3.05), were significantly associated with regular PDMP use under voluntary conditions. Under mandatory conditions, increased odds of PDMP use were associated with pharmacies that stocked naloxone (OR: 1.88; 95% CI 1.06-3.34). Pharmacists working in regional and rural areas had significantly lower odds (OR: 0.35; 95% CI 0.20-0.63) of always using the PDMP, as did pharmacists with > 15years' experience (OR: 0.24; 95% CI 0.11-0.51) once use was mandated. Given that PDMP utilisation was slower or less regular amongst pharmacists located in regional and rural areas, pharmacists with more years of experience and those not already supplying naloxone, targeted training aimed at these sub-populations may be beneficial.

U.S. state policies on opioid prescribing during the peak of the prescription opioid crisis: Associations with opioid overdose mortality.

In response to the opioid overdose crisis in the United States, many states implemented policies to guide opioid prescribing, but their impact on overdose mortality (prescription and non-prescription) remains poorly understood. We examined the impact of U.S. state opioid-prescribing policies on opioid overdose mortality following implementation. We calculated opioid overdose mortality rates from 1999-2016 by U.S. state using the CDC WONDER database, overall and separately for overdose deaths from prescription and non-prescription opioids. For each state, policies active on 1/1/2014 were reviewed for the presence and strength of six provisions recommending judicious opioid prescribing practices; "strong" provisions used the words "should," "shall," or "must". Interrupted time series (ITS) tested the association of each strong provision with overdose mortality, overall and separately for prescription and non-prescription opioids, in the two years following implementation. Sensitivity analyses compared between states, used time-lagged analyses, and excluded synthetic opioids from non-prescription opioid deaths. All six provisions had consistent direction of effect in ITS and sensitivity analyses. Strong provisions for prescriber training and limits on opioid dose reduced the slope of overall and prescription opioid overdose mortality in both ITS and sensitivity analyses. Reduced non-prescription opioid overdose mortality was only associated with strong provision for prescriber training. Some provisions had a negative impact. In ITS, strong provision for prescriber response to misuse increased the slope of non-prescription opioid overdose mortality. Strong provision for mandatory prescription drug monitoring program use had no relationship with overdose mortality in ITS and was associated with increased overall, prescription and non-prescription opioid overdose mortality in between-state sensitivity analysis. Opioid prescribing policies in U.S. states at the peak of the prescription opioid epidemic had modest mortality benefit, and did not reduce non-prescription opioid overdose mortality. A strong provision for prescriber training was the only provision associated with reduced prescription and non-prescription opioid overdose mortality. These findings can inform future efforts addressing prescription drug epidemics.

Electronic prescription monitoring and the opioid epidemic

To combat the nationwide opioid epidemic, many states have implemented policies that require prescribers to check a patient's prescription history with Prescription Drug Monitoring Programs (PDMPs) prior to initiating or refilling opioid prescriptions. Using a difference‐in‐differences approach, we show that after states mandated PDMP use, opioid prescriptions decreased by 6.1% as intended. However, PDMP mandates had the unintended effect of driving existing opioid users towards more lethal illicit substitutes such as heroin. We found that reductions in prescription rates were accompanied by unprecedented rises in heroin overdose deaths: there were 6.37 more heroin‐related deaths per million population per year—a 50.1% increase—following PDMP mandates. Although stronger PDMP mandates (e.g., based on comprehensiveness, legal enforcement, integration with other health records, and interstate information sharing) reduced opioid prescriptions, we also find that stronger mandates inadvertently increased heroin overdose deaths. Additional analyses show that the substitution effect was not statistically significant among states with lower preexisting levels of pain reliever dependence, lower heroin availability, and greater access to substance abuse treatment. These findings point to an important policy implication: supply‐side restrictions such as mandated PDMP need to account for possible demand‐side substitution effects.

Impact of Mandated Online Prescription Drug Monitoring Programs on Opiate Analgesic Use and Patient-Reported Pain during Radiotherapy for Oropharyngeal Cancer

<h3>Purpose/Objective(s)</h3> Owing to the dramatic rise in opiate-related deaths, the use of online prescription drug monitoring programs (PDMPs) concurrent with new laws restricting opiate administration has become commonplace across the U.S. Some oncologists, however, have expressed concerns that they may unintentionally limit treatment access to at-risk oncology populations. As opiates are frequently used in the acute management strategies for those undergoing radiotherapy for squamous cell carcinoma of the oropharynx, we sought to evaluate changes in short-term opiate prescription use following the implementation of mandated use of an online PDMP in an outpatient radiation oncology practice. <h3>Materials/Methods</h3> Between July of 2017 and December of 2019, 64 patients with biopsy-confirmed oropharyngeal squamous cell carcinoma undergoing curative-intent radiotherapy were evaluated and divided into two cohorts: (1) 26 patients treated 1 year before and (2) 38 patients treated 1.5 years following mandated PDMP use and implementation of new opiate prescription laws. The primary endpoint was opiate prescriptions during therapy and within 3 months after therapy as well as patient-reported pain per the Defense and Veterans Pain Rating Scale. Opiate doses were treated as the response in a series of chi-square tests using a three-level format: no vs. 40 to 3000 vs. 3000+ MME. Cochran-Mantel-Haenszel chi-square analysis with the row mean score test statistic assessed any proportional shifts in dose rates between strata of selected prognostic factors. <h3>Results</h3> The median total opiate doses were 975 MME and 1025 MME in the pre- and postintervention groups with no significant differences in MMEs prescribed (p=0.8441). There was also no difference in patient-reported uncontrolled pain (p=0.38) between the treatment cohorts. Univariate analysis showed tonsillar/soft-palate subsite (p<0.01) and alcohol use (p=0.04) were associated with higher rates of prescribed opioids. While 75% of patients (n=48) received opiates during their acute care, 78% (n=50) were off all prescription narcotics by 3 months or sooner following treatment. <h3>Conclusion</h3> Although potential concerns that mandated PDMP use would affect opiate utilization, there was no associated change in total opiate use by MME for the management of acute pain during radiotherapy for patients with oropharyngeal squamous cell carcinoma nor differences in patient-reported uncontrolled pain. Furthermore, despite high utilization of opiates during radiotherapy, few patients continued use past 3 months after treatment.

National Estimates and Physician-Reported Impacts of Prescription Drug Monitoring Program Use.

Despite widespread adoption of state prescription drug monitoring programs (PDMPs), it is unclear how often PDMPs are accessed through an electronic health record system (EHR-PDMP integration), or whether efforts to make PDMPs easier to access and use have improved their utility. To produce national-level estimates on the use of PDMPs among office-based physicians and benefits associated with their use. We use nationally representative survey data to produce descriptive statistics on PDMP use and associated benefits among office-based physicians in the USA. 1398 office-based physicians who prescribe controlled substances. We examined physician-reported ease and frequency of PDMP use, and how EHR-PDMP integration affects frequency and ease of use. Multivariate models were used to assess whether characteristics of PDMP use were related to physician-reported benefits such as reduced prescribing of controlled substances and perceived improvements in clinical decision-making. In 2019, two-thirds of office-based physicians in the USA reported frequent use of their state PDMP and over three-quarters reported they were easy to use. Both frequency and ease of use were positively correlated with PDMP integration status. Respondents who frequently checked their state's PDMP were 8.7 percentage points (95% CI -.4 to 17.8) more likely to report perceived benefits and reported 2.2 (95% CI 1.54 to 2.83) more benefits. Respondents who indicated their PDMP was easy to use were 12.7 percentage points (95% CI .040 to .214) more likely to report perceived benefits and reported 0.94 (95% CI 0.26 to 1.61) more benefits. Our findings suggest efforts to make PDMPs easier to access and use aided physicians in making informed clinical decisions that may not be captured by reduced prescribing alone. Efforts to further increase frequency and ease of use-including advancing a standards-based approach to PDMP and EHR data interoperability-may further increase the benefit of PDMPs.

Provider perspectives and experiences following the integration of the prescription drug monitoring program into the electronic health record

Prescription drug monitoring programs (PDMPs) are a public health tool for prescribers and pharmacists to monitor controlled substance use at the patient level. The objectives of this study were to (1) assess attitudes about the PDMP and perceived changes in experience and decision-making following integration into the electronic health record (EHR), and (2) identify barriers to optimal PDMP use and user recommendations for improvement. This descriptive study used an electronic survey to obtain feedback from prescribers and pharmacists at a single academic medical center. Descriptive statistics were calculated, and textual data were analyzed. Of 1480 PDMP users 208 responded (14.1%). Responses demonstrated the integration of the PDMP into the EHR simplified log-in and access to PDMP information resulting in more frequent access and perceived improvement of care quality. Barriers included technical issues accessing the PDMP within the EHR and the lack of integration of other state PDMPs. Overall, the benefit of integrating the PDMP into the EHR was positive but largely limited to streamlining log-in and patient selection. Recommendations for improvement include addressing technological issues and education on PDMP interpretation and integrating new features that may modify prescribing, referral, and co-prescribing behaviors.
