Snapshot

Summary

A nurse-led program designed to improve adherence to antiretroviral medication regimens for patients with human immunodeficiency virus/acquired immunodeficiency syndrome who are homeless or live in marginal housing used standard clinical classifications to identify client needs and then develop and deliver a set of interventions tailored to those needs. A randomized controlled trial found that the program had no meaningful impact on adherence with medication regimens.

Problem Addressed

Promoting adherence to antiretroviral medication regimens among human immunodeficiency virus/acquired immunodeficiency syndrome (HIV/AIDS) patients is difficult, with the degree of adherence varying based on patient characteristics, complexity of the treatment regimen, the client–provider relationship, the clinical setting, and illness severity.
  • Near-perfect adherence needed: In contrast to those with other chronic diseases, HIV/AIDS patients require nearly perfect (at least 95 percent) adherence to maintain their health. High levels of adherence are needed to decrease viral loads (ideally to nondetectable levels), reduce the risk of HIV viral mutations that may confer resistance to the medications,1 and increase immune system capability.2
  • Limited patient knowledge: Many HIV/AIDS patients, particularly those who are homeless or live in marginal housing, have knowledge, skill, and resource deficits related to medication adherence and the management of side effects.

Description of the Innovative Activity

This nurse-led program was designed to improve adherence to medication regimens for patients with HIV/AIDS by first assessing client needs using a structured tool and then developing a set of interventions tailored to meet those needs. Key elements of the program are described below:
  • Patient recruitment: Participants were recruited from a public HIV/AIDS clinic in Houston, TX. Recruitment signs were posted in waiting areas within the clinic. Potential participants contacted the study nurse to express their interest in participating in the trial. Eligible participants were consented and received $20 for each of the four visits they attended, plus $10 for a supplemental literacy survey. From this sample of 243 participants, 75.3 percent reported that they were unemployed, and 53.1 percent had no health insurance.
  • Initial visit to assess client needs: Nurses used a method known as client adherence profiling to help identify client needs that can be met through nursing interventions.3 Client adherence profiling assesses the following client characteristics: (a) medication-taking knowledge, (b) reasons for missing medications, (c) self-rated adherence, (d) perceived medication side effects, (e) medication troubles (e.g., getting prescriptions filled), and (f) ways used to remember to take medications. Client adherence profiling also assesses four aspects of the client–provider relationship: (a) client perceptions of provider’s technical skill, (b) affective tone of relationship, (c) communication, and (d) overall satisfaction.
  • Development of tailored interventions: Based on the client adherence profiling scores, the nurse assigns diagnoses (i.e., client problems) from the Clinical Care Classification System (formerly called the Home Health Care Classification).4 The nurse then develops and delivers a tailored set of interventions (a process known as intervention tailoring) designed to address the needs and problems identified in the client adherence profiling. The most common of these interventions are (1) education on medication compliance (received by 98.3 percent of clients), (2) self-care management of perceived side effects (72 percent), and (3) education about memory devices (slightly more than half). Additional interventions focus on coping support, stress control, education on energy conservation, and arranging for meals and other needed services. Overall, just over one-half (51.3 percent) of clients receive at least one intervention. The nurse documents all interventions on a client adherence profiling–intervention tailoring form for evaluation purposes during subsequent visits.

Results

A randomized controlled trial comparing an intervention to a control group found that the program resulted in no significant change in client adherence to medication regimens.
  • No difference in medication adherence: Multiple methods were used to assess adherence, including self-reporting on two different measures, electronic monitoring of pill bottle opening, pill counts, and pharmacy refill records. The data consistently show no significant difference in adherence between the intervention and control groups.5
  • Little association between measures: There was little correlation across the five different methods for measuring medication adherence, which suggests that the adherence instruments are measuring different behaviors. The lack of congruence among adherence measures has been reported in other studies.6-8

What They Learned

Back to Top
There are a number of potential reasons for the lack of significant differences in medication adherence between the intervention and control groups, including the following:
  • Knowledge and skills alone are insufficient for behavior change; motivation is also a key component. This program did not incorporate any specific behavioral theory in assessing and developing interventions for patients.
  • The frequency and time of the tailored interventions may not have been sufficient for some participants.
  • It is unclear whether the participants intended to change their adherence behaviors. In addition, the extent to which financial remuneration played a role in recruiting participants who may have lacked motivation to improve medication adherence is not known.
  • Although the client adherence profiling–intervention tailoring form was designed to ease the documentation burden, it is possible that insufficient detail was available to adequately assess whether the intensity of the intervention was sufficient to change medication adherence among many participants.
