    Preventing loss to follow up to improve health outcomes

    • Early identification of patients at risk of dropping off treatment
    • Timeously intervene to prevent patients from defaulting on treatment
    • Monitor effectiveness of patient retention interventions for ongoing improvement

    Preventing loss to follow up

    BroadReach Consulting's Patient Retention Solution

    Keeping HIV positive patients on treatment is vital to bringing HIV into epidemic control and achieving the UNAIDS “90-90-90” targets:



    90% of HIV+ individuals
    aware of their status



    90% of diagnosed patients on sustained treatment



    90% of treated patients achieving viral suppression

    Patients who drop out of treatment have poor health outcomes and increase the risk of viral transmission. The term ‘Loss to follow up” (LTFU) is used to describe patients who drop out of care.

    The challenge of LTFU is magnified in underserved communities. Promising interventions to increase patient engagement are hampered by capacity constraints. Scalable technologies deployed elsewhere to promote adherence remain out of reach, exacerbated by technical and regulatory challenges.

    Key benefits to the program

    01. Improved patient outcomes and overall program impact

    Foresight gives programs the ability to pre-emptively intervene and prevent loss to follow up, keeping more patients on treatment and saving lives.

    Impact of the Patient Retention Solution on Programs - Despite intervention

    02. Program cost efficiencies

    Preventing loss to follow up (LTFU) saves the costs incurred to bring a lost patient back into treatment and avoids catastrophic cost escalation due to issues associated with drug resistance. This ultimately enables programs to spend budgets more efficiently and effectively.

    03. Improved efficacy of patient retention interventions

    The BroadReach Consulting Patient Retention Solution enables programs to track which interventions yield positive results and which do not, and refine interventions as needed.

    The power of technology

    Product features of the At Risk Patient List

    Folder Number + Gender + Date of Birth (DoB): De-identified data is used to protect patient identity

    Date of Birth: DoB is one of many input variables that will influence a patients risk score

    Staff Allocated + Cadre of Case Coordinator ‘feature’: Ensuring clear resource commitment to actioning patient retention interventions, the program can measure whether one care giver performs better or worse than another and apply corrective action as well as the customized intervention efficacy

    Approach and methodology

    Predictive analytics that prevents patient loss to follow up

    Consistent with good analytics practice, we developed models on a subset of the data of 500,000 HIV positive patients. We used this to train the model, and then applied the resulting models to the broader dataset to validate the quality of the model. We continued to tune the models through numerous iterations of feature and selection.

    Our modelling approach was able to achieve sufficiently robust scores across the various predictive models to be insightful at clinical operations level. The confidence in predictions ranged from 68 - 75%, which was then improved to 80 - 88% in the final tuned model.


    The model, whilst built on a large data set, can be utilised on a smaller data set with the same level of confidence.
