Study Reveals Urban Missouri Faces Higher High-Dose Opioid Prescription Rates

A recent study conducted by researchers at the University of Missouri School of Medicine has indicated that urban areas in Missouri exhibit significantly higher rates of high-dose opioid prescriptions. This trend raises concerns regarding the potential for increased opioid use disorder among affected populations.

The findings, featured in the Journal of Opioid Management, highlight the risks associated with high-dose opioid medications, commonly prescribed for severe pain relief. While opioids such as hydrocodone and oxycodone can be effective for pain management, they also carry a risk of addiction and dependence. Patients may develop a tolerance, requiring larger doses to achieve the same relief, which can lead to serious health implications.

Mirna Becevic, the lead researcher, noted that several factors contribute to the likelihood of developing an opioid use disorder. These include the intensity of the pain, duration of opioid usage, dosage levels, and existing medical conditions, including neurological and mental health disorders.

In their analysis, Becevic and her research team examined over 3 million Medicaid claims from Missouri spanning from 2017 to 2021. They identified 306,432 individual cases and compared these against data from the 2018 U.S. Census and the 2020 report on primary care shortages.

The study revealed that male patients and individuals aged up to 60 were more frequently prescribed high doses of opioids. In contrast, prescribing patterns for younger adults appeared more cautious, possibly due to heightened awareness regarding the opioid crisis.

Becevic explained that chronic pain tends to increase with age, which may account for the observed prescribing trends. Interestingly, the data indicated a notable decline in high-dose prescriptions for individuals over 60, likely attributable to a greater risk of adverse effects and potential drug interactions in this age group.

Moreover, the research identified a correlation between high-dose opioid prescriptions and urban areas, particularly those with higher proportions of veterans and primary care providers. This suggests that urban settings may be particularly vulnerable to the prescription practices leading to opioid misuse.

The implications of these findings underscore the necessity for effective public health strategies aimed at addressing the ongoing opioid crisis. Becevic emphasized the importance of education and training for clinicians in evidence-based pain management and opioid use disorder treatment, pointing to programs like Show Me ECHO as valuable resources.

Despite existing clinical guidelines recommending against high-dose opioid prescriptions, the study highlights that such practices persist in certain regions. Becevic cautioned that the results, while informative, are specific to Missouri and may not be applicable to other states or populations, given the diverse demographics, healthcare policies, and access issues across the country.

As the opioid crisis continues to evolve, further research is essential to explore long-term trends and the rationale behind high-dose opioid prescribing. The findings from this study provide crucial insights into the risk factors affecting opioid prescriptions among Missouri patients, paving the way for more targeted interventions.
