The Impact of a Walk-in Human Immunodeficiency Virus Care Model for People Who Are Incompletely Engaged in Care: The Moderate Needs (MOD) Clinic.

Background: The Moderate Needs (MOD) Clinic in Seattle, Washington provides walk-in primary care for people with human immunodeficiency virus (HIV) who are incompletely engaged in standard care. Methods: We evaluated HIV outcomes among patients enrolled in the MOD Clinic (within group analysis) and, separately, among MOD patients versus patients who were MOD-eligible but did not enroll (comparison group analysis) during January 1, 2018-September 30, 2021. The primary outcome was viral suppression ([VS] viral load <200 copies/mL); secondary outcomes care engagement (≥2 visits ≥60 days apart) and sustained VS (≥2 consecutive suppressed viral loads ≥60 days apart). In the within group analysis, we examined outcomes at time of MOD enrollment versus 12 months postenrollment. In the comparison group analysis, we examined outcomes at the time of MOD eligibility versus 12 months posteligibility. Both analyses used modified Poisson regression. Results: Most patients in MOD (N = 213) were unstably housed (52%) and had psychiatric comorbidities (86%) or hazardous substance use (81%). Among patients enrolled ≥12 months (N = 164), VS did not increase significantly from baseline to postenrollment (63% to 71%, P = .11), but care engagement and sustained VS both improved (37% to 86%, P < .001 and 20% to 53%, P < .001, respectively) from pre-enrollment to 12 months postenrollment. In the comparison group analysis, VS worsened in nonenrolled patients (N = 517) from baseline to 12 months posteligibility (82% to 75%, P < .001). Patients in the MOD Clinic who met criteria for the comparison group analysis (N = 68) were more likely than nonenrolled patients to be engaged in care at 12 months posteligibility (relative risk, 1.29; 95% confidence interval, 1.03-1.63). Conclusions: The MOD Clinic enrollment was associated with improved engagement in care. This model adds to the spectrum of differentiated HIV care services.

HIV Care for Patients With Complex Needs: A Controlled Evaluation of a Walk-In, Incentivized Care Model.

BACKGROUND: New approaches are needed to provide care to persons with HIV who do not engage in conventionally organized HIV clinics. The Max Clinic in Seattle, Washington, is a walk-in, incentivized HIV care model located in a public health STD clinic that provides care in collaboration with a comprehensive HIV primary care clinic (the Madison Clinic). METHODS: We compared outcomes in the first 50 patients enrolled in Max Clinic and 100 randomly selected matched Madison Clinic control patients; patients in both groups were virally unsuppressed (viral load [VL] >200 copies/mL) at baseline. The primary outcome was any VL indicating viral suppression (≥1 VL <200 copies/mL) during the 12 months postbaseline. Secondary outcomes were continuous viral suppression (≥2 consecutive suppressed VLs ≥60 days apart) and engagement in care (≥2 medical visits ≥60 days apart). We compared outcomes in the 12 months pre- and postbaseline and used generalized estimating equations to compare changes in Max vs control patients, adjusting for unstable housing, substance use, and psychiatric disorders. RESULTS: Viral suppression improved in both groups pre-to-post (20% to 82% Max patients; P < .001; and 51% to 65% controls; P = .04), with a larger improvement in Max patients (adjusted relative risk ratio [aRRR], 3.2; 95% confidence interval [CI], 1.8-5.9). Continuous viral suppression and engagement in care increased in both groups but did not differ significantly (continuous viral suppression: aRRR, 1.5; 95% CI, 0.5-5.2; engagement: aRRR, 1.3; 95% CI, 0.9-1.9). CONCLUSIONS: The Max Clinic improved viral suppression among patients with complex medical and social needs.
