Family experiences with pediatric antiretroviral therapy: responsibilities, barriers, and strategies for remembering medications

Biomarker-confirmed suboptimal adherence to isoniazid preventive therapy among children with HIV in western Kenya

OBJECTIVES

The aim of this study was to assess the level and correlates of biomarker-confirmed adherence to isoniazid (INH) preventive therapy (IPT) among children with HIV (CLHIV).

DESIGN

This prospective cohort study assessed adherence among CLHIV on IPT in public sector HIV clinics from 2019 through 2020.

METHODS

Adherence was assessed by pill counts or caregiver or self-reports, and urine biomarkers (in-house dipstick and Isoscreen). Both urine biomarker tests detect INH metabolites within 48 h of ingestion. Consistent adherence was defined as having positive results on either biomarker at all visits. Correlates of biomarker-confirmed nonadherence at each visit were evaluated using generalized estimating equations. The in-house dipstick was validated using Isoscreen as the reference.

RESULTS

Among 97 CLHIV on IPT with adherence assessments, median age was 10 years (IQR 7-13). All were on ART at IPT initiation (median duration 46 months [IQR 4-89]); 81% were virally suppressed (<1000 copies/ml). At all visits, 59% ( n  = 57) of CLHIV reported taking at least 80% of their doses, while 39% ( n  = 38) had biomarker-confirmed adherence. Viral nonsuppression (adjusted risk ratio [aRR] = 1.65; 95% confidence interval [95% CI] 1.09-2.49) and the sixth month of IPT use (aRR = 2.49; 95% CI 1.34-4.65) were independent correlates of biomarker-confirmed nonadherence at each visit. Sensitivity and specificity of the in-house dipstick were 98.1% ( 94.7 - 99.6%) and 94.7% ( 88.1 - 98.3%) , respectively, versus Isoscreen.

CONCLUSION

Biomarker-confirmed adherence to IPT was sub-optimal and was associated with viral nonsuppression and duration of IPT. Urine dipstick testing may be useful in assessing adherence to IPT in clinical care.

High risk of virologic failure among HIV-infected children and adolescents routinely followed-up in Littoral region of Cameroon

Virological response to antiretroviral therapy (ART) remains a challenge for HIV-infected children and adolescents due to non-optimization of pediatric ART for resource-limited settings. In this study, we aimed to investigate factors associated with virologic failure (VF) in HIV-infected-children and adolescents on ART in Cameroon. A prospective patient-based cohort study was conducted among HIV-infected children (0-9 years) and adolescents (10-19 years) followed-up between November 2018 and October 2019 in 38 healthcare centers located in the Littoral region of Cameroon. The 1st viral load (VL) was assessed after 6 months of ART initiation and the 2nd VL between 3 and 6 six months later in patients with VL ≥1000 copies/ml in accordance with the national algorithm using Abbott Real-Time HIV-1 Viral Load Assay. Multivariate analyses were performed to identify the determinants of higher risk of VF. Of 1,029 HIV-infected children and adolescents (393 children and 636 adolescents), 801 (77.8%) cumulatively presented with VL <1000 copies/mL within 12 months on ART. Adolescents were more likely to have VF than children (24.5% vs 18.3%, OR: 1.39; 95%CI: 1.00-1.93; p = 0.047). Patients followed-up in decentralized care units were significantly more likely to have VF compared to those attending the accredited treatment centers (26.1% vs 16.6%, OR: 1.88, 95%CI: 1.37-2.58; p<0.001). Our findings show a high rate of VL suppression (VLS, 77.8%) among HIV-infected children and adolescents, albeit lower than the established target of 90%. Being adolescent and patients followed in the decentralized care units are high risk factors for VF, thereby necessitating routine therapeutic education of patients and guardians in resource limited countries to improve VLS.

Barriers to medication adherence in children, adolescents, and young adults prescribed anticoagulation

Pediatric and adolescent and young adult (AYA) thromboembolism is treated with anticoagulation, but little is known about adherence. The aims of this study were to describe barriers to adherence among children and AYAs (ages 0-25 years) prescribed anticoagulants and to explore the relationship between barriers and self-reported adherence. Nearly 75% of patients and caregivers reported barriers, and a larger number of barriers was associated with missing at least one dose in the past month per both patient (r_pb  = 0.48, p = .01) and caregiver (r_pb  = 0.52, p = .01) report. Limitations, clinical implications, and future directions are discussed.

Standardized enhanced adherence counseling for improved HIV viral suppression among children and adolescents in Homa Bay and Turkana Counties, Kenya

Viral suppression is suboptimal among children and adolescents on antiretroviral therapy (ART) in Kenya. We implemented and evaluated a standardized enhanced adherence counseling (SEAC) package to improve viral suppression in children and adolescents with suspected treatment failure in Homa Bay and Turkana. The SEAC package, implemented from February 2019 to September 2020, included: standard procedures operationalizing the enhanced adherence counseling (EAC) process; provider training on psychosocial support and communication skills for children living with HIV and their caregivers; mentorship to providers and peer educators on EAC processes; and individualized case management. We enrolled children and adolescents aged 0 to 19 years with suspected treatment failure (viral load [VL] >1000 copies/mL) who received EAC before standardization as well as those who received SEAC in a pre-post evaluation of the SEAC package conducted in 6 high-volume facilities. Pre-post standardization comparisons were performed using Wilcoxon-Mann-Whitney and Pearson's chi-square tests at a 5% level of significance. Multivariate logistic regression was performed to identify factors associated with viral resuppression. The study enrolled 741 participants, 595 pre- and 146 post-SEAC implementation. All post-SEAC participants attended at least 1 EAC session, while 17% (n = 98) of pre-SEAC clients had no record of EAC attendance. Time to EAC following the detection of high VL was reduced by a median of 8 days, from 49 (interquartile range [IQR]: 23.0-102.5) to 41 (IQR: 20.0-67.0) days pre- versus post-SEAC (P = .006). Time to completion of at least 3 sessions was reduced by a median of 12 days, from 59.0 (IQR: 36.0-91.0) to 47.5 (IQR: 33.0-63.0) days pre- versus post-SEAC (P = .002). A greater percentage of clients completed the recommended minimum 3 EAC sessions at post-SEAC, 88.4% (n = 129) versus 61.1% (n = 363) pre-SEAC, P < .001. Among participants with a repeat VL within 3 months following the high VL, SEAC increased viral suppression from 34.6% (n = 76) to 52.5% (n = 45), P = .004. Implementation of the SEAC package significantly reduced the time to initiate EAC and time to completion of at least 3 EAC sessions, and was significantly associated with viral suppression in children and adolescents with suspected treatment failure.

Antiretroviral Therapy and Retention in Care Experiences and Needs of Adolescents Living with HIV in Southern Ethiopia

Background

Adolescents with HIV are faced with challenges when taking care of their medication, which affects their treatment adherence. Therefore, this study aimed to explore the experiences and needs of adolescents living with HIV regarding their antiretroviral therapy adherence and retention in care in southern Ethiopia.

Methods

An inductive qualitative study design was applied to explore adolescents’ experiences and needs regarding antiretroviral treatment adherence and retention in care in southern Ethiopia. Eighteen adolescents were selected from five HIV care and treatment facilities by purposive sampling. The interviews followed an interview guide, translated into the participants’ national language. The interviews were transcribed verbatim and the first author developed a coding frame for the analysis by using NVivo software including meaning units and codes, which were discussed by all authors. Then, sub-themes and themes were identified and analyzed by qualitative content analysis.

Results

The results were described in two themes: barriers and facilitators for treatment adherence and retention in care. Barriers were described in seven subthemes and facilitators in three subthemes. Forgetting to take medication, hiding information, or non-disclosure of HIV status, being afraid to collect treatment drugs, being in an orphanage, and school activities were described as barriers while support from health care workers, families, personal motivation to cope with medication-related problems were described as facilitators for antiretroviral therapy adherence and retention in care.

Conclusion

Adherence is a major challenge among adolescents living with HIV in Ethiopia, with barriers that are unique to this age group and their living conditions. Therefore, interventions should be targeted to address privacy barriers, stigma, and lack of support.

HIV virological non-suppression and its associated factors in children on antiretroviral therapy at a major treatment centre in Southern Ghana: a cross-sectional study

BACKGROUND

Children living with human immunodeficiency virus (HIV) infection require lifelong effective antiretroviral therapy (ART). The goal of ART in HIV-infected persons is sustained viral suppression. There is limited information on virological non-suppression or failure and its associated factors in children in resource limited countries, particularly Ghana.

METHODS

A cross-sectional study of 250 children aged 8 months to 15 years who had been on ART for at least 6 months attending the Paediatric HIV clinic at Korle Bu Teaching hospital in Ghana was performed. Socio-demographic, clinical, laboratory and ART Adherence related data were collected using questionnaires as well as medical records review. Blood samples were obtained for viral load and CD4⁺ count determination. Viral load levels > 1000 copies/ml on ART was considered virological non-suppression. Logistic regression was used to identify factors associated with virological non-suppression.

RESULTS

The mean (±SD) age of the study participants was 11.4 ± 2.4 years and the proportion of males was 53.2%. Of the 250 study participants, 96 (38.4%) had virological non-suppression. After adjustment for significant variables, the factors associated with non-suppressed viral load were female gender (AOR 2.51 [95% CI 1.04-6.07], p = 0.041), having a previous history of treatment of tuberculosis (AOR 4.95 [95% CI 1.58-15.5], p = 0.006), severe CD4 immune suppression status at study recruitment (AOR 24.93 [95% CI 4.92-126.31], p < 0.001) and being on a nevirapine (NVP) based regimen (AOR 7.93 [95% CI 1.58-1.15], p = 0.005).

CONCLUSION

The prevelance of virological non-suppression was high. Virological non-suppression was associated with a previous history of TB treatment, female gender, severe CD4 immune suppression status at study recruitment and being on a NVP based regimen. Early initiation of ART and phasing out NVP-based regimen might improve viral load suppression in children. In addition, children with a history of TB may need focused measures to maximize virological suppression.

Pain, Anger, and the Fear of Being Discovered Persist Long after the Disclosure of HIV Serostatus among Adolescents with Perinatal HIV in Rural Communities in South Africa

Informing adolescents of their HIV serostatus forms part of their HIV care and is a critical step in the transition to adult clinical care services. This article describes the experiences of adolescents with perinatal HIV in regard to disclosure, and examines the impact disclosure has on their emotional health and behaviors. We used a qualitative design to conduct interviews with 21 adolescents aged 12-19 years recruited from a rural district in South Africa. NVivo 10 computer software was used for thematic analyses. All adolescents were aware of their HIV-serostatus. The findings show that delayed disclosure, was a one-time event, and was unplanned. Disclosure occurred at the clinic rather than the adolescent's home. For most adolescents, feelings of anger, pain, sadness, negative perceptions of self, internalized stigma, and denial persisted long after disclosure occurred. They lived in constant fear of having their serostatus being discovered, and they developed a sense of fear of self-disclosure. Their negative emotions undermined treatment adherence. In contrast, other adolescents that described disclosure as a positive event, had accepted their HIV status, and lived similar to other adolescents. The prolonged negative reactions underscore the importance of ongoing post-disclosure interventions for adolescents in rural settings where psychosocial support services are insufficient to address their emotional wellbeing.

Validation and confirmatory factor analysis of the pediatric Adherence Barriers to Continuous Positive Airway Pressure Questionnaire

OBJECTIVE

To evaluate and refine a newly proposed factor structure for the Adherence Barriers to Continuous Positive Airway Pressure Questionnaire (ABCQ) and to present psychometric data from a large, geographically diverse sample of children and young adults with sleep disordered breathing (SDB) treated with positive airway pressure (PAP).

METHODS

A sample of 181 patients prescribed PAP for treatment of SDB, ages 8-21 years, and caregivers (n = 234) of patients ages 2-21 years, completed the ABCQ during routine sleep medicine clinic visits. Adherence data from participants' PAP machines were obtained via electronic download, providing objective data on PAP adherence immediately preceding the clinic visit during which the ABCQ was completed.

RESULTS

A three-factor structure (1. Behavior, Beliefs, Environment, 2. Emotional Barriers, & 3. Physical Barriers) exhibited good model fit in confirmatory factor analysis. Results indicate that the ABCQ has strong psychometric properties, including good internal consistency among subscales and strong convergent validity with objectively measured PAP adherence. Analysis of the Receiver Operator Characteristic Curve (ROC) yielded an ABCQ total cut-off score of 46.5 for patient report and 53.5 for caregiver report. Scores above the cutpoint predicted nonadherence to PAP, defined as failure to use PAP for ≥4 h on 70% of nights.

CONCLUSIONS

The three-factor ABCQ appears to be a useful patient- and caregiver-report instrument to measure barriers to PAP treatment in children and young adults with sleep disordered breathing.

Assessing Medical Neglect in HIV-Exposed or Infected Children

Human Immunodeficiency Virus (HIV) causes a chronic illness requiring lifelong medical care to prevent opportunistic infections and death. It is important to identify medical neglect in children that are perinatally exposed to or living with human immunodeficiency virus and to take steps to prevent it. Diagnosis of medical neglect must be considered in the context of the caregivers' understanding of the risks of harm, and the logistical, cultural and social factors that may influence their actions or non-actions. When medical neglect as failure of treatment or prevention of infection is suspected, medical providers should work collaboratively with caregivers to assess and address barriers to adherence and to provide resources and support. Medical neglect may be diagnosed if repeated preventive efforts fail.

The association between diagnosis disclosure and adherence to antiretroviral therapy among adolescents living with HIV in sub-Saharan Africa: a protocol for systematic review and meta-analysis

INTRODUCTION

More than eight in ten of the world's 1.65 million adolescents living with human immunodeficiency virus (ALHIV) live in sub-Saharan Africa (SSA). Suboptimal adherence to antiretroviral therapy (ART) and poor viral suppression are reported among ALHIV which may in turn compromise the gains achieved so far. The evidence on whether knowing one's own human immunodeficiency virus (HIV) status and self-disclosure to others benefit adherence to ART or not is inconclusive. This review aims to estimate the association between knowing one's HIV status and self-disclosure on adherence to ART among ALHIV in SSA.

METHODS

Comprehensive search strings will be used to identify relevant observational studies published in English up to May 2020 in major databases: Excerpta Medica database (EMBASE), PubMed, and Ovid/MEDLINE. To access African studies and also to freely access subscription-based articles, the African Index Medicus (AIM) and the WHO HINARI databases will be searched. The AfroLib database will be searched to access the gray literature of African studies. We will use the COVIDENCE software for title/abstract screening, full-text screening, quality assessment, and data extraction. Two authors will independently screen retrieved articles, and a third author authorized to resolve conflicts will handle disagreements. The Joanna Briggs Institute's (JBI) critical appraisal tools will be used to assess study quality. Appropriate statistical tests will be conducted to quantify the between studies heterogeneity and for the assessment of publication bias. We will check individual study influence analysis and also do subgroup analysis. The STATA version 14.2 will be used for statistical analysis.

DISCUSSION

A high-level adherence to ART is required to achieve adequate viral suppression and improve quality of life. Consequently, the evidence on how adherence to ART differs with knowledge of one's own HIV status and self-disclosure may help guide interventions aimed at improving adherence to ART.

Adherence to combination antiretroviral therapy among orphaned children in Dar es Salaam, Tanzania

Background

Adherence to combination antiretroviral therapy (cART) among HIV-infected children is often complicated by various factors including medication formulation, dosing frequency, drug toxicities, age and developmental stage, psychosocial and behavioural characteristics of both children and caregivers and can additionally be complicated by being an orphan.

Objectives

This study was aimed at determining the factors and the extent of their influence on cART adherence among HIV-infected orphaned children attending Care and Treatment Centres (CTCs) in Dar es Salaam, Tanzania.

Methods

A cross-sectional study was performed, which assessed adherence in HIV-positive orphaned children aged 2–14 years receiving nevirapine (NVP) based cART for at least 6 months. Data was collected using questionnaires administered to primary caregivers of HIV-infected orphaned children, the review of medical files, and the laboratory measurement of NVP plasma concentrations and CD4 counts. Adherence to cART was determined based on caregivers’ self-report, consistency of clinic attendance and NVP plasma concentrations.

Results

Among the 216 enrolled orphaned children, adherence to cART was found to be 79.6%, 82.9% and 72.2% respectively based on caregivers’ self-report, clinic attendance and NVP plasma levels. Significant reductions in NVP concentrations (< 3 µg/mL) were seen among children with poor immunological outcomes, poor clinic attendance (p < 0.05) and were suggested by caregivers’ self-reported adherence (p = 0.06). Adherence challenges identified by caregivers included financial constraints (87.5%), lengthy waiting times at clinics (75.5% spent > 2 h at the clinic) and low HIV knowledge among caregivers.

Conclusion

Significant numbers of HIV-infected orphans have poor adherence to cART ranging between 17% and 28% based on different assessment methods. Inadequate caregiver knowledge of HIV/AIDS, long clinic waiting times and forgetfulness were identified as barriers to cART adherence in these orphans.

Determining the degree of adherence to treatment in inflammatory bowel disease patients

AIM

Since the inflammatory bowel disease (IBD) is a disorder which requires continuous drug intake to induce and maintain the remission phase, finding the barriers for low adherent group, may improve the disease phase and quality of life in those patients.

BACKGROUND

IBD is defined as a chronic immune disorder with unpredictable flares. The common treatment of these diseases can be effective for inducing and maintaining remission courses. Therefore the use of long-term medication therapy is the crucial key to prevent surgery and complications in patients with IBD.

METHODS

Morisky Medication Adherence Scales (MMAS) is used for detecting level of adherence to the medicines for 137 patients with IBD. Demographic and clinical data are recorded for all patients and quality of life has been evaluated by Short-Form 36 questionnaire in 55 patients.

RESULTS

Demographic and clinical features showed no correlation with the degree of adherence. The MMAS-8 score in the low adherent group significantly different than that in the medium and high adherer group. No relation was found statistically between level of adherence and mental or physical sates (p value=0.17, 1.2) and total quality of life (p value=0.22) in patients with IBD.

CONCLUSION

Designing smart reminder and the physician's explain about adverse effects and beneficial of medicines may be effective to confront with forgetfulness and feeling comfort with treatment. Improve a strategy in order to regular measurement of adherence to medication, provides enough information about stop taking medication.

Video observations of treatment administration to children on antiretroviral therapy in rural KwaZulu-Natal

For children younger than five years, caregivers are responsible for the measurement and administration of antiretroviral medication doses to children. Failure to adhere to the regimen as prescribed may lead to high viral loads (VLs), immune suppression and ultimately drug resistance. In the content of this study, adherence refers to adequate dosing of the medication by a caregiver. Acquired drug resistance to antiretroviral therapy (ART) is prevalent amongst children in South Africa, and poor adherence to the dosing regimen by caregivers may be associated with this problem. In this qualitative study, we purposively recruited 33 caregiver–child dyads from the Hlabisa HIV Treatment and Care Programme database. Children were divided into three groups based on their VL at the time of recruitment. Children with a VL ≥ 400 cps/ml were grouped as unsuppressed (n = 11); children with a VL ≤ 400 cps/ml were grouped as suppressed (n = 12); and children with no VL data were grouped as newly initiated (n = 10). Caregiver–child dyads were visited at their households twice to document, by means of video recording, how treatment was administered to the child. Observational notes and video recordings were entered into ATLAS.ti v 7 and analysed thematically. Results were interpreted through the lens of Ecological Systems Theory and the information–motivation–behavioural skills model was used to understand and reflect on several of the factors influencing adherence within the child’s immediate environment as identified in this study. Thematic video analysis indicated context- and medication-related factors influencing ART adherence. Although the majority of children in this sample took their medicine successfully, caregivers experienced several challenges with the preparation and administration of the medications. In the context of emerging drug resistance, efforts are needed to carefully monitor caregiver knowledge of treatment administration by healthcare workers during monthly clinic visits.

Challenges and perspectives of compliance with pediatric antiretroviral therapy in Sub-Saharan Africa

More than 3 million children aged less than 15years are infected with HIV worldwide, mainly in Sub-Saharan Africa. The survival of HIV-infected children depends on their access to antiretroviral therapy whose success mainly depends on a good life-long compliance with antiretroviral therapy. Given its complexity and specificity, assessment and monitoring of pediatric compliance with antiretroviral therapy is a major challenge. There is no consensus on a gold standard for monitoring compliance with antiretroviral therapy. Compliance is also influenced by many factors related to the child, the caregiver, the healthcare staff, the healthcare system, and antiretroviral drugs. This review aimed to assess scientific knowledge on pediatric compliance with antiretroviral therapy in Sub-Saharan Africa, and to identify areas for future interventions to improve compliance. Good compliance is essential to achieve the "90% coverage of children on antiretroviral therapy" gold standard of the World Health Organization, and to eliminate HIV infection by 2030.

Understanding the acceptability and adherence to paediatric antiretroviral treatment in the new formulation of pellets (LPV/r): the protocol of a realist evaluation

BACKGROUND

Improving access to paediatric HIV treatment requires both large-scale treatment programmes and medication that is adapted to infants and children's needs. The WHO recommends lopinavir/ritonavir as first-line antiretroviral therapy for all HIV-infected children younger than 3 years. There is currently little evidence on the acceptability of, and adherence to, a formulation of this combination treatment if given in the form of pellets. This protocol presents how we will carry a realist evaluation to assess the factors that contribute to the acceptability and adherence to the new pellets formulation in 3 hospitals in Kenya.

METHODS

We structured the protocol along the realist evaluation cycle following 4 steps: (1) the initial programme theory, (2) the study design, (3) the data collection methods and (4) the data analysis plan. Theories of behavioural sciences were reviewed for frames that could provide insights into how using such new formulations may contribute to better acceptability and adherence.

ETHICS AND DISSEMINATION

This study was approved by the Institutional Review Board of the Institute of Tropical Medicine, the Ethical Committee of the University Hospital Antwerp and the Kenyatta National Hospital/University of Nairobi Ethics and Research Committee. We aim to disseminate the findings through international conferences and peer-reviewed journals and to share them with Drugs for Neglected Diseases initiative's (DNDi) programme managers and with the Kenyan healthcare providers.

DISCUSSION

In developing this study, we encountered some challenges. First, methods to measure the acceptability of any formulation and adherence to it are not standardised. The second challenge is common in realist evaluation and relates to how to choose from different potentially interesting theoretical frameworks. We identified relevant and empirically tested theories from behavioural science that may be helpful in our study. We will test them in 3 settings by exploring the multilevel factors that influence acceptability and adherence of this new paediatric Antiretroviral (ARV) formulation.

Perceptions and Experiences about Self-Disclosure of HIV Status among Adolescents with Perinatal Acquired HIV in Poor-Resourced Communities in South Africa

Background. There is limited research on the disclosure experiences of adolescents with perinatal acquired HIV (PAH). The study explores how adolescents with PAH experience living with HIV and examined their perceptions and experiences regarding disclosure and onward self-disclosure to friends and sexual partners. Methods. Thematic analysis was used to analyze in-depth interviews conducted with 37 adolescents. Findings. Adolescents received disclosure about their status at mean age of 12 years. They perceived disclosure as necessary and appreciated the truthful communication they received. Adolescents have learned to accept and live with HIV, and they desired to be healthy and normal like other people. After receiving disclosure, they found their treatment meaningful, and they adhered to medication. However, they also expressed a strong message that their HIV status was truly their secret and that self-disclosure to others will take the feeling of being normal away from them because they will be treated differently. Conclusion. Adolescents maintained secrecy in order to be accepted by their peers but also to protect themselves from stigma and isolation. Given that adolescents want to be informed of their HIV status but desire controlling self-disclosure of their HIV status, these should form the basis for development of disclosure interventions.

Children and Adolescents with Perinatal HIV-1 Infection: Factors Associated with Adherence to Treatment in the Brazilian Context

Challenges to the adherence to combination antiretroviral therapy among the pediatric population should be understood in the context of the trajectories of families, their interaction with healthcare services, and their access to material and symbolic goods. The present study analyzed individual, institutional and social factors that might be associated with the caregivers’ role in the treatment adherence of children and adolescents living with HIV (CALHIV). Based on semi-structured interviews and questionnaires applied to 69 caregivers seen at pediatric AIDS services of five Brazilian macro-regions, we observed that adherent caregivers had better acceptance of diagnosis and treatment, were less likely to face discrimination and social isolation secondary to AIDS-related stigma and tended to believe in the efficacy of treatment, and to be more optimistic about life perspectives of CALHIV. Interventions aiming to improve adherence and to promote the health of CALHIV should take in consideration the interplay of such different factors.

THE USE OF SELF-MANAGED TREATMENT STRATEGIES IN A PREDOMINANTLY LOW-INCOME, AFRICAN-AMERICAN SAMPLE OF WOMEN LIVING WITH HIV

While low-income and ethnic minority women represent a growing proportion of new HIV cases in the United States, little is known about how they manage their antiretroviral medication regimens. Using a predominantly low-income, African-American sample (N = 85), this study examined medication self-management strategies among HIV seropositive women undergoing antiretroviral therapy in a major metropolitan area. Most study participants (95%; n = 81) reported employing a specific medication management strategy during the previous week. Pillboxes, use of daily activities, and receiving reminders from another person were the most common strategies. Most participants (80.2%) employed two or more strategies. Age, education, and motivation were associated with alarm, pillbox, and visual aid usage.

HIV treatment adherence measurement and reporting concordance in youth with perinatally acquired HIV infection and their caregivers

We examined youth-caregiver adherence report concordance and association of different adherence self-report items with HIV RNA viral load (VL) in perinatally HIV-infected adolescents assessed in 2003-2008. Youth (n=194; 9-19 years) and their caregivers completed a multi-step 2-day recall, one item on last time medications were missed, and one item on responsibility for managing youths' medications. Across early (9-12 years), middle (13-15 years), and late (16+years) adolescence, both youth and caregivers reported having primary responsibility for youths' medication regimens and demonstrated poor to moderate youth-caregiver concordance on adherence items. Responses to the last-time-missed item had greater association with VL than did the 2-day recall, particularly for longer times (e.g., past month). By age group, significant associations with VL were found for caregiver reports in early adolescence, caregiver and youth reports in middle adolescence, and youth reports in late adolescence, suggesting that caregivers offer better reports of youth adherence during early adolescence, but by later adolescence, youth are better informants. Although design limitations preclude definitive conclusions about the reliability and validity of specific adherence items, this study suggests important issues related to age group, caregiver vs. youth informants of adherence, and recall periods for child adherence assessment that warrant further research.

Medical nonadherence in pediatric HIV: psychosocial risks and intersection with the child protection system for medical neglect

Nonadherence to antiretroviral treatment has serious health implications for HIV-infected children, at times warranting referral to child protective services (CPS). The current study of 134 children with perinatally acquired HIV infection aimed to investigate rates of treatment adherence and CPS involvement, multilevel variables associated with nonadherence, and the manner in which these risks operated together in the prediction of adherence outcomes. Risk factors for nonadherence were grouped on the basis of confirmatory factor models, and factor score regression was carried out to determine which factors were uniquely predictive of adherence. A series of indirect effects models were then tested in order to examine how these factors operated together in the prediction of adherence. Results showed that almost half of the sample demonstrated suboptimal adherence to treatment, and in one-fifth, CPS was involved for medical neglect. Caregiver Health, Caregiver Involvement, Caregiver Acceptance, and Child Adaptation were predictive of nonadherence, and together explained 54% of the variance in treatment adherence. There were significant indirect effects of Caregiver Health on adherence that operated through Caregiver Involvement and Child Adaptation and an indirect effect of Caregiver Involvement on adherence through Child Adaptation. Findings extend current literature that has independently linked various factors predictive of medical adherence in pediatric HIV by showing separate but simultaneous associations with nonadherence and unique pathways to adherence involving multilevel risks. Healthcare and child welfare implications are discussed.

Viral suppression and adherence among HIV-infected children and adolescents on antiretroviral therapy: results of a multicenter study

OBJECTIVE

To evaluate treatment adherence among perinatally-infected pediatric human immunodeficiency virus (HIV) patients followed in pediatric centers in Brazil.

METHODS

This was a cross-sectional multicenter study. Medical records were reviewed and adherence scale, assessment of caregivers' quality of life (WHOQOL-BREF), anxiety, depression, and alcohol/substances use/abuse were assessed. Outcomes included self-reported 100% adherence in the last three days and HIV viral load (VL)<50 copies/mL. Statistical analyses included contingency tables and respective statistics, and multivariable logistic regression.

RESULTS

260 subjects were enrolled: 78% children and 22% adolescents; 93% of caregivers for the children and 77% of adolescents reported 100% adherence; 57% of children and 49% of adolescents had VL<50 copies/mL. In the univariate analyses, HIV diagnosis for screening due to maternal infection, lower caregiver scores for anxiety, and higher scores in physical and psychological domains of WHOQOL-BREF were associated with 100% adherence. Shorter intervals between pharmacy visits were associated with VL<50 copies/mL (p ≤ 0.01). Multivariable regression demonstrated that caregivers who did not abuse alcohol/other drugs (OR=0.49; 95% CI: 0.27-0.89) and median interval between pharmacy visits<33 days (OR=0.97; 95% CI: 0.95-0.98) were independently associated with VL<50 copies/mL; whereas lower caregiver scores for anxiety (OR=2.57; 95% CI: 1.27-5.19) and children's HIV diagnosis for screening due to maternal infection (OR=2.25; 95% CI: 1.12-4.50) were found to be independently associated with 100% adherence.

CONCLUSIONS

Pediatric HIV programs should perform routine assessment of caregivers' quality of life, and anxiety and depression symptoms. In this setting, pharmacy records are essential to help identify less-than-optimal adherence.

Longitudinal stability of specific barriers to medication adherence

OBJECTIVE

Higher levels of barriers are related to lower medication adherence and negative medical outcomes in pediatric transplant recipients. Although total number of barriers appears to be stable over time, it is unclear whether the same is true for specific barriers. This study examined the frequency of endorsement and the stability of specific barriers over 18 months.

METHOD

Participants included 63 parents and 51 adolescents and young adults. Transplant types included 39 kidneys, 16 livers, 10 hearts, and 1 double lung. Participants completed measures of perceived barriers to adherence at Time 1 (T1) and Time 2 (T2).

RESULTS

The majority of parent- and adolescent-reported specific barriers showed a positive relationship from T1 to T2. Few specific barriers showed significant differences in the level of endorsement between time points.

CONCLUSION

Specific barriers to medication adherence tend to be stable over time. Patients' specific barriers appear unlikely to change without targeted intervention.

The development and implementation of theory-driven programs capable of addressing poverty-impacted children's health, mental health, and prevention needs: CHAMP and CHAMP+, evidence-informed, family-based interventions to address HIV risk and care

This article describes a program of prevention and intervention research conducted by the CHAMP (Collaborative HIV prevention and Adolescent Mental health Project; McKay & Paikoff, 2007 ) investigative team. CHAMP refers to a set of theory-driven, evidence-informed, collaboratively designed, family-based approaches meant to address the prevention, health, and mental health needs of poverty-impacted African American and Latino urban youth who are either at risk for HIV exposure or perinatally infected and at high risk for reinfection and possible transmission. CHAMP approaches are informed by theoretical frameworks that incorporate an understanding of the critical influences of multilevel contextual factors on youth risk taking and engagement in protective health behaviors. Highly influential theories include the triadic theory of influence, social action theory, and ecological developmental perspectives. CHAMP program delivery strategies were developed via a highly collaborative process drawing upon community-based participatory research methods in order to enhance cultural and contextual sensitivity of program content and format. The development and preliminary outcomes associated with a family-based intervention for a new population, perinatally HIV-infected youth and their adult caregivers, referred to as CHAMP+, is described to illustrate the integration of theory, existing evidence, and intensive input from consumers and healthcare providers.

Relationship between viral load and self-report measures of medication adherence among youth with perinatal HIV infection

Poor adherence to antiretroviral therapy (ART) contributes to disease progression and emergence of drug-resistant HIV in youth with perinatally acquired HIV infection (PHIV +), necessitating reliable measures of adherence. Although electronic monitoring devices have often been considered the gold-standard assessment in HIV research, they are costly, can overestimate nonadherence and are not practical for routine care. Thus, the development of valid, easily administered self-report adherence measures is crucial for adherence monitoring. PHIV+youth aged 7-16 (n = 289) and their caregivers, enrolled in a multisite cohort study, were interviewed to assess several reported indicators of adherence. HIV-1 RNA viral load (VL) was dichotomized into >/≤ 400 copies/mL. Lower adherence was significantly associated with VL >400 copies/mL across most indicators, including ≥ 1 missed dose in past seven days [youth report: OR = 2.78 (95% CI, 1.46-5.27)]. Caregiver and combined youth/caregiver reports yielded similar results. Within-rater agreement between various adherence indicators was high for both youth and caregivers. Inter-rater agreement on adherence was moderate across most indicators. Age ≥ 13 years and living with biological mother or relative were associated with VL >400 copies/mL. Findings support the validity of caregiver and youth adherence reports and identify youth at risk of poor adherence.

The effect of different intervention programs on treatment adherence of HIV-infected children, a retrospective study

In HIV-infected children, long-term adherence to combination anti-retroviral therapy (cART) is difficult. In this retrospective study, we evaluated the effect of two different treatment adherence programs on treatment adherence (as indicated by cART failures) and the need for additional supportive care measures in a cohort of 31 HIV-infected children between 3 and 18 years of age. In a follow-up period of 6 years, we evaluated the treatment adherence at baseline (before introduction of any treatment adherence program in 2004) and compared this to cART failures during two treatment adherence programs (in respectively 2006 and 2009). The need for additional supportive care measures (the frequency of hospitalizations, daily observed treatment, use of child protection service, attendance of special schools, and placement in foster homes) was also evaluated at these three time points. The first treatment adherence program focused on increasing patient's obedience by imposing negative measures in case of treatment failure, whereas the second program aimed to increase treatment adherence by rewarding optimal medication intake. Prior to start of any treatment adherence intervention program, cART failures were observed in 29% of the pediatric patients. After introduction of the first treatment adherence program, cART failures decreased to 6%. During the second treatment adherence program, the cART failures remained equally low (10%), but the need for some specific additional supportive care measures (the frequency of hospitalizations and placement in foster homes) was importantly reduced. Treatment adherence programs are effective in increasing treatment adherence to cART in HIV-infected children. A novel reward treatment interventional program as an addition to social supportive care programs is a promising new positive enforcement program and can reduce the need for additional supportive care programs. Further prospective studies are needed to evaluate the long-term effect of this new treatment intervention program.

Adherence to the Treatment of Children Living with HIV: A Conceptual Analysis

Objetivo: Analizar el concepto de la adherencia al tratamiento de los niños que viven con el VIH, expresado en la literatura de la salud, haciendo la identificación de sus atributos esenciales, antecedentes y consecuencias. Método: método evolutivo de análisis de concepto propuesto por Rodgers para evaluar los 17 artículos que se centraron en el tema del estudio. Resultados: identificado como atributos esenciales que caracterizan el concepto. A raíz de la prescripción por el binomio niño-familia, la disponibilidad de formulaciones pediátricas, acompañamiento clínico y de laboratorio regulares, adecuación de los hábitos y toma de decisiones compartida entre el cuidador y el niño. Conclusiones: con base en los elementos identificados, se elaboró una definición consensuada en que se entiende la adherencia al tratamiento de los niños VIH positivos como un proceso de colaboración que va más allá de tomar los medicamentos, teniendo en cuenta el dinamismo, los aspectos de la familia, la vida cotidiana de los niños, la parte social, económica y estructural del fenómeno en estudio. Los hallazgos permiten una comprensión más amplia del concepto y ofrecer subsidios para la prestación de la atención integral dirigida a controlar la enfermedad y mejorar la calidad de vida. Se sugiere la formación de grupos multidisciplinarios dedicados a la realización de trabajos educativos sobre las dificultades en el cumplimiento, la promoción de un espacio de intercambio de experiencias y el desarrollo de estrategias de afrontamiento

Multiple measures reveal antiretroviral adherence successes and challenges in HIV-infected Ugandan children

BACKGROUND

Adherence to HIV antiretroviral therapy (ART) among children in developing settings is poorly understood.

METHODOLOGY/PRINCIPAL FINDINGS

To understand the level, distribution, and correlates of ART adherence behavior, we prospectively determined monthly ART adherence through multiple measures and six-monthly HIV RNA levels among 121 Ugandan children aged 2-10 years for one year. Median adherence levels were 100% by three-day recall, 97.4% by 30-day visual analog scale, 97.3% by unannounced pill count/liquid formulation weights, and 96.3% by medication event monitors (MEMS). Interruptions in MEMS adherence of ≥ 48 hours were seen in 57.0% of children; 36.3% had detectable HIV RNA at one year. Only MEMS correlated significantly with HIV RNA levels (r = -0.25, p = 0.04). Multivariable regression found the following to be associated with <90% MEMS adherence: hospitalization of child (adjusted odds ratio [AOR] 3.0, 95% confidence interval [CI] 1.6-5.5; p = 0.001), liquid formulation use (AOR 1.4, 95%CI 1.0-2.0; p = 0.04), and caregiver's alcohol use (AOR 3.1, 95%CI 1.8-5.2; p<0.0001). Child's use of co-trimoxazole (AOR 0.5, 95%CI 0.4-0.9; p = 0.009), caregiver's use of ART (AOR 0.6, 95%CI 0.4-0.9; p = 0.03), possible caregiver depression (AOR 0.6, 95%CI 0.4-0.8; p = 0.001), and caregiver feeling ashamed of child's HIV status (AOR 0.5, 95%CI 0.3-0.6; p<0.0001) were protective against <90% MEMS adherence. Change in drug manufacturer (AOR 4.1, 95%CI 1.5-11.5; p = 0.009) and caregiver's alcohol use (AOR 5.5, 95%CI 2.8-10.7; p<0.0001) were associated with ≥ 48-hour interruptions by MEMS, while second-line ART (AOR 0.3, 95%CI 0.1-0.99; p = 0.049) and increasing assets (AOR 0.7, 95%CI 0.6-0.9; p = 0.0007) were protective against these interruptions.

CONCLUSIONS/SIGNIFICANCE

Adherence success depends on a well-established medication taking routine, including caregiver support and adequate education on medication changes. Caregiver-reported depression and shame may reflect fear of poor outcomes, functioning as motivation for the child to adhere. Further research is needed to better understand and build on these key influential factors for adherence intervention development.

Barriers to treatment of paediatric obstructive sleep apnoea: Development of the adherence barriers to continuous positive airway pressure (CPAP) questionnaire

BACKGROUND

Continuous positive airway pressure (CPAP) treatment is often prescribed for youth as a treatment for obstructive sleep apnoea (OSA). Efficacy research in youth is limited, though some evidence suggests that it may relieve symptoms of OSA and possibly prevent future physical, emotional, and behavioural complications. However, the device must be used consistently for benefits to be realised. Non-adherence to medical treatment is prevalent among youth with chronic illness, yet little is known regarding adherence to CPAP in paediatric OSA.

METHODS

Using a sample of 51 youth (age 8-17 years) recruited from a paediatric sleep specialty clinic, the aims of the current study were to: (1) present descriptive data regarding CPAP adherence in youth with OSA, and (2) develop a psychometrically sound measure of barriers for adherence to CPAP use for youth with OSA.

RESULTS

Results indicated that adherence to CPAP is poor: youth in the current sample used their CPAP on average 3.35 h per night. The adherence barriers measure demonstrated excellent psychometric properties.

CONCLUSIONS

The adherence barriers to CPAP questionnaire has the potential to be a useful clinic-based tool for identifying patient-specific issues with CPAP adherence in youth with OSA.

Outcomes and processes at a camp for youth with HIV/AIDS

The impact of HIV/AIDS on the lives of youth with this chronic illness suggests the need for additional support as youth develop. Summer camp can serve as a therapeutic intervention for youth with HIV/AIDS. Using a case study employing observations, focus groups, and interviews, we examined outcomes associated with participation in a camp for youth with HIV/AIDS, and program processes that influenced outcomes. Findings showed that camp played a major developmental role for youth. Three outcomes of camp emerged: (a) forming caring connections (awareness of commonalities, lack of isolation); (b) feeling reprieve and recreation (fun activities, anticipation of and reflection on camp, sense of freedom); and (c) increasing knowledge, attitudes, and skills (conflict management, disclosure, skill learning and education, medication adherence). Processes included formal and informal education, staff-camper interactions, long-term relationships, outside-of-camp support, activities, planning for camper needs, accessibility, and freedom from worry. We discuss implications for youth programs.

Medication beliefs and perceived barriers in adolescent renal transplant patients and their parents

Understanding patient beliefs about medications and perceived barriers is important for optimal medical management. Differentiating adolescent views from parents' perceptions would enhance care by increasing communication about regimens and reducing obstacles. This study explored beliefs about medications and perceived barriers among 40 adolescent kidney transplant patients and their parents. Younger adolescents reported greater concern about medication harmfulness (t(38) = 2.190, p < 0.05) and more barriers, particularly for practical problems including forgetfulness, organization, and coordination (t(38) = 2.049, p < 0.05). Fathers with a lower education reported their children having greater challenges with medications due to taste and size (t(37) = 2.933, p < 0.01). Families with incomes in the low and high levels expressed that their children need more medication reminders (F (2, 35) = 7.815, p < 0.005), and adolescents from lower-income families perceived medication to be more harmful (F (2, 36) = 3.815, p < 0.05). Adolescents expressed challenges with practical aspects of medication taking, whereas parents were more focused on medications being necessary for their health. Adolescent renal patients experience challenges to medication management that may differ from their parents, findings that can help tailor interventions to improve medication management.

Predictors of long-term anti-retroviral therapy effectiveness among Brazilian HIV-1-infected children in a hybrid scenario: what really matters?

The study objective was to evaluate the effectiveness and durability of highly active anti-retroviral therapy (HAART) in perinatally HIV-1-infected children and adolescents and its predictors. A historical cohort study was done at IMIP's Hospital in Recife, Brazil. The study included 195 subjects, 102 (52.3%) had successful response to HAART with a mean time of any HAART use of 4.9 [standard deviation (SD) 2.5; min. 0.7, max. 9.9] years. The time to failure of first HAART was negatively associated with male sex [relative hazard (RH) = 0.5, p = 0.021) and living out of metropolitan area (RH = 0.4, p = 0.009), and associated with Centres for Diseases Control and Prevention (CDC) immunological Stage 1 (RH = 2.9, p = 0.003) and patients who were adherent (RH = 2.2, p = 0.003). HAART success rate and mean time durability was similar to developed country data. However, the main predictors of success were: female sex, living in a metropolitan area, CDC1 immunological category and adherence.

Antidepressant and antipsychotic use and adherence among Medicaid youths: differences by race

The purpose of our study is to use Medicaid data to examine the relationship between race and (a) whether youth with schizophrenia or depression diagnoses receive anti-psychotic and antidepressant prescriptions and (b) adherence to anti-psychotics and antidepressants. The analysis is based on claims files from January 1, 2000 through June 30, 2001. To assess adherence, we used the Proportion of Days Covered (PDC) measure. Multivariable logistic regression was used to analyze the data. Black children with schizophrenia were significantly less likely to be adherent to anti-psychotics during a quarter than White children. White children with depression were significantly more likely to receive an antidepressant prescription and they were significantly more adherent during a quarter than Black children. Providers should make sure to investigate both youth and caregiver concerns, fears, and barriers to using these medications and work with the families to develop strategies to improve medication use among youth.

Assessing medication adherence of perinatally HIV-infected children using caregiver interviews

Medication adherence is critical for children's HIV treatment success, but obtaining accurate assessments is challenging when complex measurement technologies are not feasible. Our goal was to evaluate a multidimensional adherence interview designed to improve on existing adherence measures. Data from caregivers (N = 126) of perinatally infected children were analyzed to determine the ability of the revised interview guide to detect potential treatment nonadherence. Questions related to viral load (VL) on a bivariate level included proportion of doses taken in the previous 3 days and 6 months, caregivers' knowledge of prescribed dosing frequencies, and caregivers' reports of problems associated with medication administration. VL was not associated with 3-day recall of missed doses. In multivariate analyses, only caregiver knowledge of prescribed dosing frequencies was uniquely associated with VL. Our modified interview appears to successfully identify family struggles with adherence and to have the capacity to help clinicians address medication adherence challenges.

Starting HIV-positive babies on antiretroviral treatment: perspectives of mothers in Soweto, South Africa

INTRODUCTION

Timely and effective initiation of antiretroviral treatment for babies infected with the human immunodeficiency virus (HIV) is critical. Mothers' perspectives on the health care and treatment of their HIV-positive babies could affect how they engage with health care.

METHOD

A convenience sample of HIV-positive mothers was interviewed using qualitative methods. Thematic analysis was used to identify themes significant for participants as well as those relevant to health service provision.

RESULTS

These mothers seemed relatively well-informed and positive regarding their baby's care and treatment, but their understanding and practice was influenced by their own experience, observations, and fears, as well as the views of others. Having a baby on antiretroviral treatment improved their own health care motivation, but the daily reminder that it provided of the baby's status and still possible death and the prospect of their own death constituted a heavy emotional burden.

DISCUSSION

The study highlights the complexity, ambiguity, and interlocking nature of the mothers' understandings, attitudes, and concerns. This contrasts with the often fairly one-dimensional nature of communication by health care providers and highlights the need to engage more comprehensively with mothers.

[Predictors of changes in drug regimens for treating AIDS in children]

To identify the causes of changes in therapeutic regimens for treating AIDS in children infected through vertical transmission. This was a case-control study in which the control group consisted of 49 children who had not had any changes to their antiretroviral regimen and the case group consisted of 62 children who had had changes between January 2000 and December 2005. Data from the patients' medical files and a semistructured interview were used. The data analysis was carried out using the SPSS software, and the chi-square test and logistic regression were applied. The main causes of changes in treatment were: increased viral load (48.4%), poor immunological response (46.6%) and clinical worsening (35.5%) of the patients. The adjustment of the data through logistic regression analysis showed that drug intolerance was the variable that contributed most to the change in medication ((adjusted) OR: 79.94; 95% CI: 6.28 -1034.55). Adherence was not shown to be responsible for changes in the anti-retroviral therapy, and this was attributable to the organization of the service and actions of the interdisciplinary team.

Barriers to oral medication adherence for adolescents with inflammatory bowel disease

OBJECTIVE

To identify family-reported, adherence-related barriers for adolescents with inflammatory bowel disease (IBD) and examine their relationship to 6-MP/azathioprine and 5-ASA medication adherence.

METHODS

Participants included 74 adolescents, aged 13-17 years, diagnosed with IBD and their caregivers. Adolescents and caregivers jointly completed a measure of barriers to medication adherence. Adherence to medication was measured by family-report, pill-count, and serum assay.

RESULTS

Families endorsed one to seven total barriers to medication adherence. The most commonly reported barriers included forgetting, being away from home, and interference with an activity. Neither demographic nor disease severity variables were related to the total number of reported barriers. Fewer total reported barriers was related to better adherence by adolescent and maternal report.

CONCLUSION

Most families experience at least one barrier to treatment adherence. Effective problem-solving around these barriers and its integration into future treatment protocols may help improve medication adherence in the pediatric IBD population.

A comparison of adherence assessment methods utilized in the United States: perspectives of researchers, HIV-infected children, and their caregivers

This study sought to elucidate methodological issues in adherence research by comparing multiple methods of assessing adherence to antiretroviral medication. From 2003 to 2004, 24 youths with vertically infected HIV disease (mean age = 14.0 years; range, 8-18) and their caregivers participated in a 6-month study. These children were all on highly active antiretroviral therapy (HAART) and were relatively healthy (mean CD4 absolute count = 711.8 +/- 604.5). Adherence was assessed with the Medication Event Monitoring System (MEMS), pill counts, and interviews. Patients and caregivers completed the Perceptions of Adherence Study Participation (PASP) questionnaire. MEMS provided the most detailed adherence information, and good reliability was indicated by significant correlations with medical markers. Pill counts provided similar adherence rates, while patients and caregivers reported nearly perfect adherence in interviews. Problems were experienced with each method: MEMS were expensive, had cap malfunctions, and lack a consistent guiding principle for data interpretation. With pill counts, families forgot to bring all medication bottles to clinic, and interviews were compromised by social desirability and difficulty reaching families by telephone. Most patients and caregivers believed study participation improved the child's adherence, although PASP ratings were unrelated to adherence at the study endpoint. While MEMS may be most reliable, pill counts offer comparable data and are less costly, while interviews seemed least accurate in this study. Most participants reported positive perceptions of their research experience. A consensus among researchers is needed for defining and measuring adherence, and specific recommendations are offered for achieving this goal.

Evolution of child mental health services in primary care

OBJECTIVE

Although the importance of mental health assessment and treatment in primary care is increasingly recognized, the research that underlies current practices largely stems from a considerable body of non-mental health primary care studies. Our purpose was to describe trends in research over the past 2 decades and to suggest further key items for the research agenda.

METHODS

We reviewed the literature broadly on health services research in pediatrics, especially studies of changes in primary care practice, and examined recent articles in primary care mental health services.

RESULTS

The evolution of primary care mental health services for children has been slow, but the focus of research has changed with the development of clinical improvements. Proposals to deliver more effective services have evolved over the past 40 years in a series of approaches that paralleled initiatives in the broader fields of medicine and pediatrics. Current trends in electronic technology, practice consolidation and coordination, and personalized medicine are likely to increase the pace of change in mental health services for primary care.

CONCLUSIONS

The evolution of pediatric mental health services in primary care suggests a continuing expansion from a focus initially on provider behavior and quality to a growing attention to patient and systems' behavior over time and within communities.
