Matching person-level information stored in public health, medical, and human services datasets can enhance the understanding of opioid overdose risk factors and interventions.<\/jats:p><\/jats:sec><jats:sec><jats:title>Objective<\/jats:title><jats:p>This study compares approximate match versus exact match algorithms to link disparate datasets together for identifying persons at risk from an applied perspective.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>This study used statewide prescription drug monitoring program (PDMP), arrest, and mortality data matched at the person-level using an approximate match and 2 exact match algorithms. Impact of matching was assessed by analyzing 3 independent concepts: (1) the prevalence of key risk indicators used by PDMP programs in practice, (2) the prevalence of arrests and fatal opioid overdose, and (3) the performance of a multivariate logistic regression for fatal opioid overdose. The PDMP key risk indicators included (1) multiple provider episodes (MPE), or patients with prescriptions from multiple prescribers and dispensers, (2) high morphine milligram equivalents (MMEs), which represents an opioid\u2019s potency relative to morphine, and (3) overlapping opioid and benzodiazepine prescriptions.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Prevalence of PDMP-based risk indicators were higher in the approximate match population for MPEs (n\u2009=\u20094893\/1\u00a0859\u00a0445 [0.26%]) and overlapping opioid\/benzodiazepines (n\u2009=\u200957\u00a0888\/1\u00a0859\u00a0445 [4.71%]), but the exact-basic match population had the highest prevalence of individuals with high MMEs (n\u2009=\u2009664\/1\u00a0910\u00a0741 [3.11%]). Prevalence of arrests and deaths were highest for the approximate match population compared with the exact match populations. Model performance was comparable across the 3 matching algorithms (exact-basic validation area under the receiver operating characteristic curve [AUC]: 0.854; approximate validation AUC: 0.847; exact + zip validation AUC: 0.826) but resulted in different cutoff points balancing sensitivity and specificity.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>Our study illustrates the specific tradeoffs of different matching methods.
