About this study

Official title: Improving HIV Prevention Outcomes: Insights on Long-Acting Injectable (LAI) HIV Pre-Exposure Prophylaxis (PrEP) Patient-Reported Medication Preferences, Adherence, and Clinical Outcomes (IMPACT) in a Southern US State

The goal of this observational study is to learn about the real world effectiveness, patient satisfaction and clinical outcomes of LAI PrEP with lenacapavir (LEN) versus cabotegravir (CAB) through surveys and interviews.

Participants receiving or initiating LAI PrEP part of their regular medical care will complete surveys and interviews at three study visits over the course of 12 months.

Being tested
Interview and survey to evaluate patient reported outcomes between the two medications.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. LAI-SQ-6 Survey, Long-Acting Injectable Satisfaction Questionnaire

    The primary endpoint of this study is to compare treatment satisfaction of CAB and LEN LAI PrEP, as measured by the Long-Acting Injectable Satisfaction Questionnaire (LAI-SQ-6), adapted for LAI therapy from the Treatment Satisfaction Questionnaire for Medication- 9 (TSQM-9) [12]. The minimum score possible on this questionnaire is 0 and the maximum score possible on this questionnaire is 36. Higher scores indicate a higher satisfaction, while lower scores suggest areas for improvement in patient experience with injectable medication.

    Measured: Time of Enrollment, 6 months, 12 months

Secondary outcomes (8)
  1. Persistence with Injectable PrEP

    Calculated by the proportion of days covered (PDC) and identification of gaps in treatment using medication administration data.

    Measured: 6 months and 12 months

  2. Injection Adherence

    Measured by the Injection Adherence Rating Scale (IARS). The IARS is a Yes/No questionnaire intended to capture valuable insight from patients using long-acting injectable medications, allowing providers to improve adherence by addressing concerns related to adherence to injection schedule, perception of the injection, and the impact of side effects. .

    A patient is considered adherent if they answer "No" to questions 1-5 and "Yes" to questions 7-8 (indicating consistent attendance to injections, confidence in the protective effect of the medication, and positive engagement with the regimen).

    A patient is considered non-adherent if they answer "Yes" to questions 1-5 (indicating missed or delayed injections due to forgetfulness or lack of consistency) or "Yes" to questions 9-10 (indicating negative feelings about the injection process, which may signal discomfort or side effects affecting adherence).

    Measured: Enrollment, 6 months, 12 months

  3. Injection Site Reactions

    Injection Site Reaction Questionnaire (ISRQ) for patient-reported symptoms - DAIDS criteria for grading of infusion and injection site reactions. The ISRQ is a Yes/No questionnaire and is a tool intended to capture valuable insight from patients using long-acting injectable medications, allowing providers to assess patient perceived severity of reactions to injectable drugs.

    Scoring and Interpretation:

    Mild Injection Site Reaction (ISR): A patient is considered to have mild ISR if they respond "Yes" to 1-2 symptoms.

    Moderate ISR: A patient is considered to have moderate ISR if they respond "Yes" to 3 symptoms.

    Severe ISR: A patient is considered to have severe ISR if they respond "Yes" to ≥ 4 symptoms.

    Measured: Enrollment, 6 months, 12 months

  4. HIV Prevention Effectiveness

    Reviewing HIV test results to confirm new HIV diagnoses during the study period.

    Measured: Baseline, 6 months, and 12 months

  5. Incidence of Co-occurring STIs

    Reviewing routine STI testing outcomes to determine the incidence of Co-occurring STIs.

    Measured: Enrollment, 6 months, and 12 months

  6. Patient perceptions and preferences

    Explored in a subset of 20 patients through the injectable PrEP Experience Interview (IPEI).

    Measured: Enrollment, 6 months, and 12 months

  7. Retention in Care

    Evaluated through the proportion of appointments attended (PAA) and the proportion of patients with a scheduled end-of-study visit (PESV).

    Measured: 6 months and 12 months

  8. Visit Burden Index

    Evaluated through the number of PrEP-related visits per patient (i.e. provider visits, injection visits, laboratory visits, and urgent/ emergency department visits for adverse reactions to PrEP and/or additional STI screening).

    Measured: 6 months and 12 months
