This study examines the proportion of blood-borne and sexually transmitted infections among patients with substance use disorder in a low-barrier medication clinic, and evaluates the success of treatment and linkage to care. Viral infections include HIV, Hepatitis A, B, and C, while bacterial infections include Syphilis, Gonorrhea, and Chlamydia.

Background • Low-Barrier to Access Programs (LBAP) rapidly link people with substance use disorders (SUD) to addiction treatment, including medication • However, the role of LBAP in addressing other aspects of SUD, including infectious complications, remains uncertain
Objective • To determine the proportion of blood-borne and sexually transmitted infections among patients with SUD presenting to an LBAP • To evaluate the proportion of individuals successfully treated and/or linked to care, defined as attendance of a referral appointment for infection treatment • Viral: • HIV • Hepatitis A • Hepatitis B • Hepatitis C • Bacterial: • Syphilis • Gonorrhea • Chlamydia

SETTING: Faster Paths to Treatment • Launched in August 2016 at Boston Medical Center • Funded through Massachusetts DPH Bureau of Substance Addiction Services’ Opioid Urgent Care Center Grant • Multidisciplinary • Rapid access to Medication for Addiction Treatment (MAT) • Referral for detox, residential recovery programs • Linkage to OBAT, primary care, behavioral health
Patient Referral Source • ED • Addiction Consult Service • Word of Mouth • Recovery Programs • Primary Care Co-located with phlebotomy, pharmacy, ED RN Intake Visit • UDS • Screening labs MD Intake Visit Faster Paths Intake Process Transition to Long Term Care • OBAT • MMTP • Residential Treatment
Methods • A retrospective chart review was performed of patients presenting to the LBAP for intake between January 1st – September 30th, 2017 • Data gathered via manual chart extraction • Total of 421 intake visits during study period • 17 patients had multiple intake visits during study period • 11 patients were screened for detox only • Total of 393 unique patients
Demographics and Social Determinants of Health • Total N of 393 unique patients • Median age 38 (Range 20-69) • 29% Female • 16% Hispanic • 49% Housing Insecurity
Results • Of 393 patients who completed intake, 258 (66%) reported injection drug use
HIV 393 Patient Intakes 24% (97/393) Patients Not Screened 76% (299/393) Patients Screened 40% (39/97) with negative HIV Ag/Ab testing on file 50% (49/97) no prior testing on file 2.3% (9/393) with known HIV infection 0.3% (1/299) HIV Ag/Ab positive known infection 99% (297/299) HIV Ag/Ab negative 0.3% (1/299) HIV Ag/Ab positive new diagnosis 41% (16/39) negative HIV Ag/Ab within 3 months of intake Referred for treatment and did not attend appointment. Linkage to care efforts ongoing 59% (23/39) with older negative testing on file
Hepatitis C 393 Patient Intakes 77% (303/393) Screened at Intake 23% (93/393) Not Screened 12% (11/93) No testing on file 57% (172/303) HCV Ab reactive 43% (131/303) HCV Ab non-reactive 46% (43/93) Self-Reported HCV +, no test on file 42% (39/93) Recent test for HCV on file 41% (16/39) HCV Ab - 39% 68/172 Newly HCV Ab + 60% (104/172) Known HCV Ab + 59% (23/39) HCV Ab + 31% (21/68) RNA not detected 69% (47/68) HCV RNA detected 32% (15/47) attended referral appointment
393 Patient Intakes Hepatitis B 72% (285/393) Screened at Intake 28% (111/393) Not Screened 14% (15/111) recently tested 43% (122/285) S Ag + Immune from Vaccination 21% (59/285) C Ab+, Cleared Infection 1% (4/285) S Ag + 2 known chronic infection 1 new chronic HBV infection 1 new acute HBV infection 1 referred to OSH for treatment 75% (3/4) attended referral appointment
393 Patient Intakes Hepatitis A 65% (255/393) Screened at Intake 35% (140/393) Not Screened 81% (114/140) No prior testing on file 17% (24/140) Prior testing available 56% (143/255) IgG positive 44% (112/255) IgG negative 29% (7/24) Prior IgG negative 71% (17/24) Prior IgG positive
Syphilis 393 Patient Intakes 72% (284/393) Patients Screened 1.8% (5/284) RPR Positive 40% (2/5) TPPA negative 60% (3/5) TPPA Positive 1 referred for treatment, did not attend appointment. Linkage to care efforts ongoing 66% (2/3) treated
Gonorrhea and Chlamydia 393 Patient Intakes 63% (248/393) Patients Screened 2% (4/248) Gonorrhea + 1% (3/248) Chlamydia + 4 (100%) Treated 3 (100%) Treated
Limitations • Limited Generalizability • Single center • BMC Infrastructure • MassHealth coverage • Retrospective Chart Review • Self-Reported data, likely under-reporting
Conclusions • LBAP patients have high rates of both sexually transmitted and blood-borne infections • Results support the inclusion of comprehensive infection screening and linkage-to-care algorithms in the LBAP setting • LBAP offer new opportunities to deploy prevention services to high risk people with SUD: • Deliver HAV and HBV vaccination • Offer HCV Treatment • Expand STI screening • Provide HIV pre-exposure prophylaxis (PrEP)
