Abstract
The opioid epidemic has taken its toll on the Midwest, a census region of the USA. The Midwest includes two census divisions: East North Central and West North Central. This study aimed (1) to characterize patient encounters of opioid use disorder (OUD) in the Midwest using the Health Facts® database; and (2) to compare selected patient and facility characteristics between the two census divisions. This study was a sub-analysis of a retrospective analysis of the Health Facts® database. For the first objective, the unit of analysis was a patient encounter. Selected patient characteristics were age, gender, marital status, race, length of stay, and patient type. Selected facility characteristics were census division and urban versus rural areas. Descriptive statistics were conducted, and population-based rates of OUD were calculated for categorical variables. For the second objective, t tests were performed for age and length of stay, and chi-square tests for categorical variables. A total of 13,129 (23.7%) encounters were in East North Central, and 42,271 (76.3%) in West North Central. Patient characteristics that were associated with the highest frequency of encounters were Caucasian, male, single, and other patient types. In addition, rural areas had a higher number of encounters than urban areas. Compared with East North Central, West North Central had a greater average age and a longer average length of stay (p<0.001). West North Central had a significantly higher proportion of patient encounters associated with patients being male, African American, single, and facilities being in rural areas (p<0.001). Compared to East North Central, patient encounters of OUD were more frequent and the average length of stay was longer than in West North Central. A significantly higher proportion of patient encounters in West North Central were associated with patients being male, African American, and single, and facilities being in rural areas.
