Another approach, being studied at Boston Medical Center and Yale--New Haven Hospital, is the frame ASSERT model, which uses Health Promotion Advocates (HPAs) or community outreach workers to disguise intervene, and refer patients with alcohol enigmas Bernstein and colleagues (1996) evaluated the effectiveness of this program in 245 participants, principally of whom had alcohol confidence After 90 days, these participants reported a 56-percent reduction in alcohol use and a 64-percent reduction in binge drinking. In addition, more than 50 percent of participants had received a treatment referral. In another evaluation of concoct ASSERT, 10,572 patients were guarded and evaluated, and 1,343 patients were referr to specialized AOD treatment programs through a 2-year period (D'Onofrio and Degutis 2003) HPAs were subsequently able to contact 811 of the referr patients, of which 711 (88 percent) had recorded in a treatment program. The outcomes suggest that this model of screening and direct linkage to treatment is feasible. Moreover, the program is likely to be sustainable, because shoot forward ASSERT is funded by HPA consultation recompenses that are included in the hospitals' billing processes
