However, combination interventions can be resource-intensive and challenging to scale up. Research is needed to identify intervention components and delivery models that maximise uptake, engagement and effectiveness. In New York City (NYC), a multicomponent Ryan White Part A-funded medical case management intervention called the Care Coordination Programme (CCP) was launched at 28 agencies in 2009 in order to address barriers to care and treatment. Effectiveness estimates based on &gt;7000 clients enrolled by April 2013 and their controls indicated modest CCP benefits over \u2018usual care\u2019 for short-term and long-term viral suppression, with substantial room for improvement.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods and analysis<\/jats:title>\n                    <jats:p>Integrating evaluation findings and CCP service-provider and community-stakeholder input on modifications, the NYC Health Department packaged a Care Coordination Redesign (CCR) in a 2017 request for proposals. Following competitive re-solicitation, 17 of the original CCP-implementing agencies secured contracts. These agencies were randomised within matched pairs to immediate or delayed CCR implementation. Data from three 9-month periods (pre-implementation, partial implementation and full implementation) will be examined to compare CCR versus CCP effects on timely viral suppression (TVS, within 4\u2009months of enrolment) among individuals with unsuppressed HIV viral load newly enrolling in the CCR\/CCP. Based on current enrolment (n=933) and the pre-implementation outcome probability (TVS=0.54), the detectable effect size with 80% power is an OR of 2.75 (relative risk: 1.41).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Ethics and dissemination<\/jats:title>\n                    <jats:p>This study was approved by the NYC Department of Health and Mental Hygiene Institutional Review Board (IRB, Protocol 18\u2013009) and the City University of New York Integrated IRB (Protocol 018\u20130057) with a waiver of informed consent.
