Piloting behavioral family systems therapy to improve adherence among adolescents with HIV: a case series intervention study

Influence of Pediatric Patients' Developmental or Chronic Health Condition Status as a Predictor of Parents' Perceptions of Patient- and Family-Centered Care

Our study aimed to estimate how a pediatric patient's health condition status influences parents' perceptions of patient- and family-centered care (PFCC). We analyzed five years (2013-2017) of Medical Expenditure Panel Survey data in efforts to expand understanding of the family influence in pediatric health encounters, using family systems theory as our theoretical lens. The sample included 36,675 parents of children with developmental or chronic health conditions who reported visiting a health-care provider within the past 12 months. The independent variable was a combined measure of any developmental or chronic health conditions previously diagnosed in the child being assessed. Dependent variables included parent reports of communication variables related to how often providers: listened; showed respect; spent enough time; and explained things well. Multivariable logistic regression was used to evaluate the odds of receiving PFCC using a dichotomous measure of PFCC quality and separate domains. Results found that 1) the dichotomous variable of PFCC showed that parents of children with health conditions were less likely to report their provider always performed all elements of PFCC compared to parents whose children did not have any health conditions; 2) parents of children with developmental or chronic health conditions were less likely to report their provider always explained things well compared to parents whose children did not have any health conditions. Efforts to improve PFCC should focus on training providers to demonstrate high-quality practices to improve health outcomes for pediatric patients with developmental or chronic conditions.

Preventing Medication Nonadherence of Youth (13-24 Years) With HIV Initiating Antiretroviral Therapy

PURPOSE

The objective of this study was to evaluate the feasibility and acceptability of a dynamic, behavioral intervention to optimize medication adherence of adolescents and young adults (AYAs) with HIV newly initiating highly active antiretroviral therapy (HAART) and explore its efficacy on adherence and disease outcomes.

METHODS

The two-arm randomized controlled trial piloted a brief, individualized intervention designed for direct integration into standard clinical care. In total, 32 AYAs with a confirmed HIV diagnosis, reportedly horizontally acquired, and recommended to initiate HAART completed a two-week placebo trial before HAART initiation and were subsequently randomized to standard of care or the individualized intervention. Adherence and disease outcomes were measured over the first six months of HAART.

RESULTS

Results supported the primary study aim regarding feasibility (recruitment = 89%, attendance = 81%-100%, intervention exercise completion = 100%) and acceptability (average favorable response = 89%). Data also supported the positive effect of the intervention on select HAART adherence measures and disease outcomes. Adherence (by pharmacy refill) declined in both groups; however, adherence declined more slowly in the intervention group versus standard of care (p < .001). In addition, 100% of participants receiving the intervention obtained an undetectable viral load by 3 months and maintained an undetectable viral load at 6 months (vs. 68.8% standard of care).

CONCLUSIONS

This is one of the first interventions to target adherence for AYAs with HIV newly initiating HAART and designed for delivery in existing clinical care settings. Future research will help confirm efficacy and the potential utility of the intervention in promoting HAART adherence from medication initiation and preventing the decrease in adherence often observed over time.

Health Knowledge and Adherence as Predictors of Viral Burden and CD4+ T-Cell Count in Youth and Young Adults Living With HIV

Health literacy influences HIV treatment for youth and, thus, is a research priority. We explored health knowledge and self-reported adherence, as indicators of health literacy, among youth living with HIV (YLWH) and the association between health literacy and health outcomes. A total of 102 YLWH ages 13-25 years participated in the study. Participants completed the Brief Estimate of Health Knowledge and Action-HIV Version; CD4 T-cell counts and viral loads were extracted from participant medical records. Participants had a moderate amount of HIV knowledge, and most reported taking their medications under most conditions. Decreasing action scores were statistically associated with an increased likelihood of having a detectable viral load. Health literacy is an important factor that should be addressed by practitioners working with YLWH. More research is needed to determine the best way to measure and improve health literacy.

Family Functioning and Childhood Obesity Treatment: A Family Systems Theory-Informed Approach

Childhood obesity recommendations advise providers to use family-based care for the treatment of youth and adolescent obesity. Family-based care, defined as the inclusion of a caregiver and a youth, is commonly conducted through behavioral interventions that target the dietary and physical activity behaviors of the attending parent-youth dyads. However, focusing on behaviors isolated to the parent and youth neglects the rest of the family members, and the larger rules, routines, communication, and dynamics in the family. Family-based interventions grounded in family systems theory (FST) target family dynamics to influence weight-related behaviors through higher-level changes in the family. The utility of using FST in childhood obesity treatment has not been extensively conceptualized or applied. Few outcome studies have reported on variables representative of FST, and even fewer FST interventions have been conducted. Because of the lack of detail on the application of FST to childhood obesity treatment, providers are left with little clarity on how to use FST in clinical encounters. We provide the background and evidence for use of FST, detail how families organize around weight-related behaviors that contribute to obesity, and on the basis of their organization, what type of treatment might be beneficial, FST-informed or family-based behavioral interventions. Finally, a suggested family-based clinical algorithm is provided detailing the use of FST through assessment, intervention, and follow-up that can be refined over time by providers and researchers committed to viewing obesity in the context of the family and family dynamics.

Transition to College and Adherence to Prescribed Attention Deficit Hyperactivity Disorder Medication

OBJECTIVE

As youth with attention deficit hyperactivity disorder (ADHD) transition to adulthood, they must learn how to manage their ADHD treatment independently. This may be challenging because many of the skills necessary to adhere to treatment (e.g., organization, planning) are impaired in those with ADHD. Using electronic monitoring, we examine trajectories of adherence to medication in a cohort of college students with ADHD. Further, we examine the effect of transitioning to college and executive functioning on adherence.

METHODS

Electronic monitors tracked adherence for 51 undergraduate students with ADHD across an academic semester. Multilevel modeling examined individual trajectories in monthly adherence and the role of transition status and self-reported executive functioning on these trajectories.

RESULTS

Overall, participants adhered to 53.53% of prescribed doses. Transition status predicted the linear slope in adherence (β = -8.95, standard error [SE] = 3.61, p < .05), with lower initial adherence among undergraduates transitioning to independence (34.17%) compared with post-transition undergraduates (67.63%; β = 33.46, SE = 8.00, p < .001). Adherence demonstrated a curvilinear change (β = -7.23, SE = 1.25, p < .001). It increased from the beginning of the semester to midterms before subsequently declining through the rest of the semester, including during final exams. Executive functioning did not predict adherence (β = -.10, SE = .02, p = .54).

CONCLUSION

Only half of all doses were taken as prescribed. Adolescents transitioning to independence demonstrated the lowest levels of adherence, suggesting that the transition to independence is a high-risk period for poor self-management of ADHD.

Antiretroviral Therapy Adherence Enhancing Interventions for Adolescents and Young Adults 13-24 Years of Age: A Review of the Evidence Base

INTRODUCTION

Youth living with HIV are highly under-represented in the evidence base for adherence interventions, despite their diverse and unique needs and barriers.

OBJECTIVE

This systematic review aimed to identify antiretroviral therapy (ART) adherence interventions specifically targeting adolescents and young adults (defined as ages 13-24) with the goal of characterizing the evidence base.

METHODS

Articles were identified using the PubMed database and cover work published through September 14, 2015.

INCLUSION CRITERIA

(1) average age 13 to 24, (2) HIV positive, (3) on or beginning ART, (4) intervention targeted ART adherence in full or in part, (5) reported adherence, viral load, and/or CD4 count outcomes. Strength of evidence was defined as level 1 [randomized controlled trial (RCT) with significance testing on outcomes], 2 (within group studies with statistical testing on outcomes), 3 (RCTs with descriptive results), or 4 (within group studies with descriptive results).

RESULTS

Of 151 articles, 10 met inclusion criteria. Published between 2003 and 2014, these studies evaluated diverse intervention approaches. Most were conducted in the US and were small pilots that have yet to be replicated despite promising results. Only 3 studies met criteria for highest level strength of evidence; 2 supported a phone-based counseling approach with adherence monitors and 1 for weekly individual and family counseling.

CONCLUSIONS

Despite nearly 20 years passing since the wide-scale availability of ART, and clear recognition that adolescents and youth adults fair worse on the cascade of HIV care, the evidence base remains sparse and underdeveloped. Promising approaches need replication and more rigorous studies are desperately needed.

Use of Placebo Pills Before Treatment Initiation in Youth with HIV: Are They Ready?

Highly active antiretroviral therapy (HAART) nonadherence is related to negative health outcomes and is well-documented in adolescents and young adults (AYAs) with behaviorally acquired HIV. Few studies describe methods to improve adherence in this population. This retrospective study describes placebo pill trial use (ie, pills with inert substance prescribed to practice taking HAART) in AYAs initiating HAART and its relation to disease outcomes. Sixty-two AYAs initiated HAART during the review period. Disease outcomes during the first year of standard clinical care were abstracted from medical records. In all, 72.6% of participants received ≥1 pill trial and 27.4% received ≥2 trials. Placebo trial use was not independently related to adherence post-HAART initiation. "Prescription" of a second trial was related to less optimal disease status over the first 6 months of treatment. Placebo trials have the potential to inform clinical care, aid in identifying AYAs at risk for nonadherence, and may provide a novel intervention strategy before/after HAART initiation.

Short message service (SMS)-based intervention to improve treatment adherence among HIV-positive youth in Uganda: focus group findings

This paper presents one of the first qualitative studies to discuss programmatic barriers to SMS-based interventions for HIV-positive youth and discusses pathways through which youth perceive them to work. We conducted six focus groups with 20 male and 19 female HIV-positive youths in two clinics in Kampala, Uganda. We find that youth commonly use SMS as over 90% of this study’s youths knew how to read, write and send messages and almost three-fourths of them had phones. Youth strongly felt that the success of this intervention hinged on ensuring confidentiality about their HIV-positive status. Key programmatic challenges discussed where restrictions on phone use and phone sharing that could exclude some youth. Participants felt that the intervention would improve their adherence by providing them with needed reminders and social support. Youths’ suggestions about intervention logistics related to content, frequency, timing and two-way messages will be helpful to practitioners in the field.

Virtual intervention to support self-management of antiretroviral therapy among people living with HIV

Background

Living with human immunodeficiency virus (HIV) necessitates long-term health care follow-up, particularly with respect to antiretroviral therapy (ART) management. Taking advantage of the enormous possibilities afforded by information and communication technologies (ICT), we developed a virtual nursing intervention (VIH-TAVIE) intended to empower HIV patients to manage their ART and their symptoms optimally. ICT interventions hold great promise across the entire continuum of HIV patient care but further research is needed to properly evaluate their effectiveness.

Objective

The objective of the study was to compare the effectiveness of two types of follow-up—traditional and virtual—in terms of promoting ART adherence among HIV patients.

Methods

A quasi-experimental study was conducted. Participants were 179 HIV patients on ART for at least 6 months, of which 99 were recruited at a site offering virtual follow-up and 80 at another site offering only traditional follow-up. The primary outcome was medication adherence and the secondary outcomes were the following cognitive and affective variables: self-efficacy, attitude toward medication intake, symptom-related discomfort, stress, and social support. These were evaluated by self-administered questionnaire at baseline (T0), and 3 (T3) and 6 months (T6) later.

Results

On average, participants had been living with HIV for 14 years and had been on ART for 11 years. The groups were highly heterogeneous, differing on a number of sociodemographic dimensions: education, income, marital status, employment status, and living arrangements. Adherence at baseline was high, reaching 80% (59/74) in the traditional follow-up group and 84% (81/97) in the virtual follow-up group. A generalized estimating equations (GEE) analysis was run, controlling for sociodemographic characteristics at baseline. A time effect was detected indicating that both groups improved in adherence over time but did not differ in this regard. Improvement at 6 months was significantly greater than at 3 months in both groups. Analysis of variance revealed no significant group-by-time interaction effect on any of the secondary outcomes. A time effect was observed for the two kinds of follow-ups; both groups improved on symptom-related discomfort and social support.

Conclusions

Results showed that both interventions improved adherence to ART. Thus, the two kinds of follow-up can be used to promote treatment adherence among HIV patients on ART.

Acceptability of Mobile Phone Technology for Medication Adherence Interventions among HIV-Positive Patients at an Urban Clinic

Mobile phone technology is increasingly used to overcome traditional barriers limiting access to care. The goal of this study was to evaluate access and willingness to use smart and mobile phone technology for promoting adherence among people attending an urban HIV clinic. One hundred consecutive HIV-positive patients attending an urban HIV outpatient clinic were surveyed. The questionnaire evaluated access to and utilization of mobile phones and willingness to use them to enhance adherence to HIV medication. The survey also included the CASE adherence index as a measure of adherence. The average age was 46.4 (SD = 9.2). The majority of participants were males (63%), black (93%), and Hispanic (11.4%) and reported earning less than $10,000 per year (67.3%). Most identified themselves as being current smokers (57%). The vast majority reported currently taking HAART (83.5%). Approximately half of the participants reported some difficulty with adherence (CASE < 10). Ninety-six percent reported owning a mobile phone. Among owners of mobile phones 47.4% reported currently owning more than one device. Over a quarter reported owning a smartphone. About 60% used their phones for texting and 1/3 used their phone to search the Internet. Nearly 70% reported that they would use a mobile device to help with HIV adherence. Those who reported being very likely or likely to use a mobile device to improve adherence were significantly more likely to use their phone daily (P = 0.03) and use their phone for text messages (P = 0.002). The vast majority of patients in an urban HIV clinic own mobile phones and would use them to enhance adherence interventions to HIV medication.

Preventing HIV among young people: research priorities for the future

OBJECTIVE

To review the current state of knowledge on the prevention of sexual transmission of HIV in adolescents and to highlight the existing gaps and priority areas for future research.

BACKGROUND

A disproportionate burden of HIV infections falls on adolescents, a developmental stage marked by unique neural, biological, and social transition. Successful interventions are critical to prevent the spread of HIV in this vulnerable population.

METHODS

We summarized the current state of research on HIV prevention in adolescents by providing examples of successful interventions and best practices, and highlighting current research gaps.

RESULTS

Adolescent interventions fall into 3 main categories: biomedical, behavioral, and structural. The majority of current research has focused on individual behavior change, whereas promising biomedical and structural interventions have been largely understudied in adolescents. Combination prevention interventions may be particularly valuable to this group.

CONCLUSIONS

Adolescents have unique needs with respect to HIV prevention, and, thus, interventions should be designed to most effectively reach out to this population with information and services that will be relevant to them.

Fluency of pharmaceutical drug names predicts perceived hazardousness, assumed side effects and willingness to buy

The impact of pharmaceutical drug names on people's evaluations and behavioural intentions is still uncertain. According to the representativeness heuristic, evaluations should be more positive for complex drug names; in contrast, fluency theory suggests that evaluations should be more positive for simple drug names. Results of three experimental studies showed that complex drug names were perceived as more hazardous than simple drug names and negatively influenced willingness to buy. The results are of particular importance given the fact that there is a worldwide trend to make more drugs available for self-medication.

Recent advances (2011-2012) in technology-delivered interventions for people living with HIV

Technology is rapidly advancing and becoming a cost effective option for intervention delivery particularly for isolated and hard to reach populations, such as people living with HIV/AIDS. A systematic review was conducted to identify recent technology based interventions for people living with HIV. The review yielded 12 studies that were grouped by the health behavior that it addressed and then the type of technology utilized. The majority of studies reviewed focused on medication adherence and used several different technologies to deliver the intervention including SMS/text messaging, cell phones and computers. This review identified several gaps in the literature particularly the lack of technology-based interventions focusing on engagement and retention to care as well as sexual risk reduction. Suggestions for future research based on these findings are provided.

Motivational Enhancement System for Adherence (MESA): pilot randomized trial of a brief computer-delivered prevention intervention for youth initiating antiretroviral treatment

OBJECTIVE

To pilot test a two-session computer-delivered motivational intervention to facilitate adherence among youth with HIV newly prescribed antiretroviral treatment (ART).

METHODS

Youth (N = 76) newly prescribed ART were recruited from 8 sites, and were randomized to the intervention or an active nutrition and physical activity control. Primary outcomes were HIV-1 viral load at baseline, 3 months, and 6 months, and self-reported adherence at 3 and 6 months.

RESULTS

Satisfaction ratings were high. Effect sizes suggested that the intervention group showed a greater drop than controls in viral load from baseline to 6 months (Cohen's d = 0.39 at 3 months; d = 0.19 at 6 months), and had greater percent undetectable by 6 months (d = 0.28). Effects sizes were medium to large for 7-day and weekend adherence.

CONCLUSIONS

A brief computer-delivered motivational intervention showed promise for youth starting ART and is ready to be tested in a full-scale clinical trial.
