Tips for Implementing the Intervention

Intervention Outcomes

  • In the original study, the time to relinkage was shorter among clients in the intervention cohort and a greater proportion was relinked to care (15% vs. 10%).
  • The second iteration of the intervention showed significant improvements in viral suppression outcomes pre- and post-intervention (from 20% to 82%).

Intervention Components

  • Assess Staff Resources and Gaps
  • Explore Existing or New Data Infrastructure
  • Engage Stakeholders
  • Generate a Local “Out-of-Care” Definition
  • Create a Client List
  • Decide on Data-Sharing Methods
  • Prioritize Client List
  • Designate Linkage Specialist
  • Establish a Communication Protocol
  • Relink and Retain Clients

Cost Analysis

Refer to the CBSI Cost Analysis Summary. You can also use the CIE Cost Analysis Calculator to create an estimate for implementing the intervention at your organization. 

Challenges and Solutions



Barriers to Care

Consider offering incentives and connecting with local service agencies to address barriers to care.

Lack of Referrals

Educate doctors about the intervention to facilitate referrals.

Lack of Administrative Support

Seek ways to sustain linkage activities to ensure active remains an organizational priority.

Data Management

Use a database that allows staff to gather, extract, and analyze client-level data.

Data-Sharing Complications

Improve the data-sharing process by gathering information about current clinic policies and lessons learned from other interventions.

Delayed Data Sharing

By improving the timeliness of data sharing, organizations can ensure that they have the most up-to-date client information, which can facilitate prompt re-linkage effort.

Undefined Staff Roles:

Clearly convey roles and responsibilities and how these may sometimes overlap.

Staff Burnout

Find ways to increase staff morale and highlight their efforts to connect people with HIV to care. Conduct consistent check-ins with staff to address barriers in real time.

Losing Sight of Long-Term Goals

Focus on sustained engagement in care as the goal rather than re-linkage. The linkage specialist can work with providers to identify barriers to sustained engagement in care so that they can address the barriers with clients.
