Prescription drug monitoring program policy reform: human and veterinary practitioner prescribing in West Virginia, 2008-2020

Unsettling trend: The alarming rise of human abuse of veterinary drugs and its consequences

Veterinary practitioners often prescribe many controlled drugs to animals that may include sedatives, tranquilizers, and painkillers. Unfortunately, many of these drugs are drugs that can be abused by humans, especially among the pet owners. Adequate measures are required to prevent or detect the misuse of veterinary drugs. In this article, the phenomenon of the rising misuse of veterinary medications by humans and their potential health hazards which can accompany the unsettling trends in society has been highlighted. This article aims to shed light on the extent of issues, exploring reasons behind human abuse and its consequences.

When Veterinary Drugs Reach Human Hospitals: A Problem-Based Learning Discussion

The delivery of drugs from the manufacturer to the hospital is a complex process. Despite numerous safeguards, lapses may occur, creating the potential for patient harm. Recently, an urban tertiary care medical center received a shipment of isoflurane bottles labeled for veterinary use. This error was not identified until the veterinary isoflurane reached the operating room automated medication dispensing system. No patients received the anesthetic. This report describes how such an error occurred, explains the differences between veterinary and human medications, and emphasizes the importance of vigilance in the drug supply chain to prevent patient harm.

Mapping the research addressing prescription drug monitoring programs: A scoping review

ISSUES

Prescription drug monitoring programs are a harm minimisation intervention and clinical decision support tool that address the public health concern surrounding prescription drug misuse. Given the large number of studies published to date and the ongoing implementation of these programs, it is important to map the literature and identify areas for further research to improve practice.

APPROACH

A scoping review was undertaken to identify the research on prescription drug monitoring programs published between January 2015 and April 2021.

KEY FINDINGS

A total of 153 citations were included in this scoping review. The majority of the studies originated from the USA and were quantitative. Results on program effectiveness are mixed and mainly examine their association with opioid-related outcomes. Unintended consequences are revealed in the literature and this review also highlights barriers to program use.

IMPLICATIONS

Overall, findings are mixed despite the large number of studies published to date. Mapping the literature identifies priority areas for further research that can advise policymakers and clinicians on practice improvement.

CONCLUSION

Results on prescription drug monitoring program effectiveness are mixed and mainly examine their association with opioid-related outcomes. This review highlights barriers to prescription drug monitoring program effectiveness related to program use and system integration. Further research is needed in these areas to improve prescription drug monitoring program use and patient outcomes.

Trends in the number of patients linked to potential vet-shopping behavior in the United States (2014-2019)

OBJECTIVE

To estimate the number of patients linked to vet-shopping behavior (the solicitation of controlled substance prescriptions from multiple veterinarians for misuse) in the United States using 2014-2019 data and characterize mandates for veterinarians to examine prescription drug monitoring programs (PDMPs) before prescribing controlled substances as of April 2021.

SAMPLE

National database reporting prescription dispensing from 92% of US pharmacies from 2014 through 2019.

PROCEDURES

The annual number of patients with dispensed prescriptions for opioid analgesics, opioid cough-and-cold medications, or benzodiazepines from ≥ 4 veterinarians was calculated. State veterinary medical associations were contacted for information on veterinarian PDMP use mandates.

RESULTS

From 2014 through 2019, the number of patients with prescriptions for any class of controlled substances from ≥ 4 veterinarians tripled from 935 to 2,875 (+207.5%). The number of patients with opioid cough-and-cold medication prescriptions from ≥ 4 veterinarians rose from 150 to 1,348 (+798.9%). The corresponding number for benzodiazepines rose from 185 to 440 (+137.8%). The corresponding number for opioid analgesics peaked at 868 in 2016 before decreasing to 733 in 2019. In April 2021, 10 states mandated veterinarians to examine PDMP records of owners or animals before prescribing controlled substances; 3 mandates excluded benzodiazepines.

CLINICAL RELEVANCE

Vet shopping in the US may be increasingly common. Mandates for veterinarians to examine PDMPs before prescribing controlled substances might facilitate detection of this behavior. However, benefits of mandates should be weighed against their potential burden on veterinarians.
