RESUMO
BACKGROUND: Evidence-based early intervention practices, such as screening, brief intervention, and referral to treatment (SBIRT), are recommended to identify unhealthy use and provide linkages to treatment to prevent substance use disorder. However, there is a lack of screening frequency recommendations. Pennsylvania (PA) SBIRT was a five-year initiative to implement SBIRT in primary care sites. This study evaluated the effects of screening policies in PA SBIRT on changes in substance use risk category over time. METHODS: Quantitative data were obtained from seven primary care sites implementing SBIRT, with patients who were screened twice using the Drug Abuse Screening Test, US Alcohol Use Disorders Identification Test, or the Alcohol, Smoking, and Substance Involvement Screening Test and experienced any risk category change (n = 1,364). Patients were 49% male, 51% female, 81% White, and 14% Black. An intercept-only generalized estimating equation model tested whether category changes between screen one and screen two were statistically significant. RESULTS: The average number of months between screenings for those experiencing a risk category change was 9.01 with a range of 0 to 46 months. There was a statistically significant change between screening one and screening two (P > 0.001), with 44% undergoing a decrease in risk category and 56% undergoing an increase in risk category. Of those undergoing an increase in risk category, 91% moved from a negative/low risk category to a positive/higher risk category. CONCLUSIONS: Results suggest that frequent screening policies may improve identification of substance use risk category changes. The results act as a catalyst to further evaluate recommended screening intervals for detecting unhealthy substance use to increase identification and patient connection.
