Few investigations to date have analyzed the epidemiology of Hansen’s disease (leprosy) in the United States, and in particular, if birth location is related to multibacillary versus paucibacillary leprosy. We collected data on 123 patients diagnosed with leprosy in Georgia from the National Hansen’s Disease Program from 1923—January 2018. A logistic regression model was built to examine the relationship between country of origin (U.S.-born or immigrant) and the type of leprosy. While the model showed no significant relationship between country of origin and type of leprosy, being Asian or Pacific Islander was associated with a higher odds of multibacillary disease (aOR = 5.71; 95% CI: 1.25–26.29). Furthermore, since the early 1900s, we found an increasing trend of leprosy reports in Georgia among both domestic born and immigrant residents, despite the overall decrease in cases in the United States during the same time period. More research is therefore necessary to further evaluate risk for multibacillary leprosy in certain populations and to create targeted interventions and prevention strategies.
Purpose: Despite the efforts of many stakeholders to reduce the risk of opioid overdose, there is limited information on the prevalence of high-risk prescription opioid use in the US.Methods: Descriptive analysis of a nationally representative 5% random sample of anonymized, longitudinal, individual-level prescription claims from IQVIA LRx between January 1, 2011 and December 31, 2016 among individuals ages 18 years or older that used a retail pharmacy. High-risk opioid use was defined as ≥50 morphine milligram equivalents per day and/or having concurrent dispensing of a benzodiazepine based on overlapping days of coverage.Results: The prevalence of high-risk opioid use among adults in the US decreased from 12.0% in 2011 to 9.4% in 2016 (p < 0.01). Declines were most pronounced among individuals ages 18-35 years (10.9%-7.0%, 36.2% decline; p < 0.01) compared to individuals age 65 years or greater (10.5%-9.8%, 6.7% decline; p < 0.01).Declines in high-risk use prevalence were observed across 49 states, with only South Dakota experiencing an increase (+13.7% relative increase). Similar to earlier years, in 2016 50.9% of all high-risk use opioid users received all their opioid prescriptions from a single prescriber, and 71.1% used a single pharmacy to fill them.
Conclusion:Despite clinically significant declines in high-risk opioid use, in 2016 nearly 1 in 10 adult retail pharmacy users remained at high-risk for opioid overdose in the US. Future clinical and policy interventions should consider targeting older adults with Medicare Part-D, including those using a single pharmacy to fill their opioid prescriptions.

Key Points• Studies examining changes, both temporal and spatial, in high-risk prescription opioid use in the United States are limited. This study found that in 2016 nearly 1 in 10 adults is potentially at risk for opioid related overdose, especially older adults.The statements, findings, conclusions, views, and opinions contained and expressed herein are not necessarily those of IQVIA or any of its affiliated or subsidiary entities.
