Improving medication compliance for juvenile rheumatoid arthritis and its effect on clinical outcome: A single-subject analysis

The efficacy of adherence interventions for chronically ill children: a meta-analytic review

OBJECTIVES

To provide quantitative information about the overall effectiveness of adherence interventions to improve adherence and health outcomes for children with chronic illnesses. To evaluate statistically the potential moderators.

METHODS

A meta-analysis was performed on 71 adherence intervention studies.

RESULTS

Weighted-mean effect size (ES) across all the adherence outcomes for group design studies was in the medium range (mean d = 0.58) and for single-subject design studies was in the large range (mean d = 1.44). The weighted mean ES across all health outcome measures for studies using group designs was in the medium range (mean d = 0.40) and for studies using single-subject designs was in the large range (mean d = 0.74).

CONCLUSIONS

Adherence interventions for children with chronic illnesses effectively increase adherence and result in some positive health benefits. Intervention and methodological variables had significant impact on ESs. High levels of heterogeneity characterized the data.

Improving adherence to medical regimens for juvenile rheumatoid arthritis

Poor adherence to medical regimens can compromise the efficacy of treatments for children and adolescents with juvenile rheumatoid arthritis (JRA). The purpose of this review is to describe medical regimens for the treatment of JRA and the rates of adherence to these regimens. We also summarize and critically the few research studies aimed at improving adherence to regimens for JRA. Finally, we summarize strategies for enhancing adherence in clinical practice.

Management of adherence and chronic rheumatic disease in children and adolescents

Medical treatment regimens for pediatric rheumatic diseases are complex, have delayed beneficial effects, and require consistent adherence over a long period of time. All of these factors place patients at risk for non-adherence that can compromise the benefits of treatment and the long-term health and quality of life for patients. This chapter provides a definition of adherence and reviews the prevalence of non-adherence to regimens for pediatric rheumatic diseases. It also describes various methods for assessing adherence, including assays, observation, electronic monitoring, pill counts, and provider or patient ratings of adherence. Studies which identify risk factors for non-adherence are also reviewed, with suggestions on how these risk factors might be addressed. The final section reviews the few studies that have reported on efforts to improve adherence to regimens for pediatric rheumatic diseases and offers strategies for providers to promote adherence with their patients.

Electronically monitored adherence to medications by newly diagnosed patients with juvenile rheumatoid arthritis

OBJECTIVE

To describe patterns of adherence to nonsteroidal antiinflammatory drugs (NSAIDs) in newly diagnosed patients with juvenile rheumatoid arthritis (JRA), and to examine demographic and disease-related variables as potential predictors of adherence.

METHODS

Adherence to NSAIDs was monitored in 48 children with JRA (mean age 8.6 years) over 28 consecutive days using an electronic monitoring device. Measures of disease activity (active joint counts, morning stiffness) and demographics (age, sex, ethnicity, socioeconomic status) were also obtained.

RESULTS

Using an 80% adherence cut point, 25 (52%) patients were classified as adherent and 23 (48%) as nonadherent. There was considerable variability across patients, with full adherence (taking all doses on time) ranging from 0 to 100% of the monitored days. Logistic regression showed that active joint count and socioeconomic status were the only significant predictors. Both were positively related to adherence. The model correctly classified 70.5% of patients as either adherent or nonadherent (Cox and Snell R(2) = 0.295, P = 0.0005).

CONCLUSION

Children newly diagnosed with JRA are more likely to adhere to an NSAID regimen if they have a greater number of active joints or their families have higher socioeconomic status. The former finding suggests that children's adherence is symptom-driven, while the latter suggests that families of lower socioeconomic status deserve special attention to address adherence issues.

Prevention of nonadherence to nonsteroidal anti-inflammatory medications for newly diagnosed patients with juvenile rheumatoid arthritis

Adherence to medications for chronic pediatric diseases decreases overtime. This randomized controlled trial evaluated a clinic-based, nurse-administered educational and behavioral intervention to prevent the anticipated drop in adherence to nonsteroidal medications among newly diagnosed patients with juvenile rheumatoid arthritis. Thirty-four participants completed the study (mean age = 8.44 years, SD = 3.96), including 19 in the experimental group and 15 in the standard-treatment (education) control group. There were significant group and Group x Time effects for adherence (assessed with an electronic monitor over a 13-month period) favoring the experimental group. In contrast, the groups did not differ significantly in disease activity or functional limitations. Factors that may have prevented detection of differences in these health parameters are dicussed.

A comparison of three types of neck support in fibromyalgia patients

OBJECTIVE

To determine the effectiveness of 3 types of neck support for patients with fibromyalgia (FMS) and their preference for the type of support.

METHODS

Thirty-five patients with FMS chose the order of application and used each type of neck support for a 2-week period, followed by a 2-week washout. The same schedule was repeated a second time. The neck supports included a Shape of Sleep pillow, two neck ruffs with one standard pillow, and a single standard pillow. All subjects received a physiotherapy treatment and educational program in the home. Outcome measures included visual analog scales (VAS) for neck pain and quality of sleep, the Fibromyalgia Impact Questionnaire (FIQ), and a neck and shoulder pain distribution diagram.

RESULTS

Analysis using Friedman's 2-way analysis of variance revealed no significant differences in any outcome measure, although there was a trend towards improvement in the FIQ and VAS neck pain and quality of sleep scores for some patients. Most participants (62.9%) preferred the Shape of Sleep pillow, 20.0% preferred cervical ruffs with one standard pillow, and 17.1% preferred a single standard pillow.

CONCLUSIONS

The results of this study are inconclusive due to the small sample size. However, from a patient's perspective, neck support is an important part of a comprehensive physiotherapy program. Most participants preferred the more rigid support of a Shape of Sleep pillow. Further research into the efficacy of the use of neck support in people with FMS is warranted.

An educational needs assessment of children with juvenile rheumatoid arthritis

OBJECTIVE

Our objective is to describe the use of the PRECEDE model (predisposing, reinforcing, and enabling causes in educational diagnosis and evaluation) to organize needs assessment data in order to define self-management behaviors and plan an educational intervention for children with juvenile rheumatoid arthritis (JRA) and their families.

METHODS

Analysis was done of needs assessment data collected from several sources: 1) literature review, 2) survey of parents of 51 children with JRA, 3) group interview of seven parents of children with JRA, 4) results of pilot programs, and 5) clinical experience of an interdisciplinary pediatric rheumatology team.

RESULTS

Two sets of interrelated behavioral factors were identified through the needs assessment: 1) those related to managing the school environment to facilitate optimal participation and to minimize school-related disability, and 2) those related to treating pain and stiffness, intervening in the disease process, and preserving joint function.

CONCLUSION

Both of these sets of behavioral factors may be related to the optimization of children's mobility, joint function, and autonomy of activities of daily living and should be targets of an educational intervention.

The validity and reliability of parental ratings of disease activity in juvenile rheumatoid arthritis

This study assessed the validity and reliability of parental ratings of morning stiffness, activity limitations, and pain complaints on a sample of 31 patients with juvenile rheumatoid arthritis (JRA). Parental ratings were found to be significant predictors of active joint counts, accounting for 40% of the variance in joint counts. Internal consistency reliability was moderately high (0.819), but test-retest reliability was moderate to low; this is not unexpected given the fluctuations in symptoms of JRA over time. The results suggest that parental ratings are valid and moderately reliable measures of disease activity in JRA. Regular monitoring of symptoms by parents could be a useful source of information for health care providers in making treatment decisions and can increase parental and patient involvement in the treatment process.

Compliance with treatment regimens for pediatric rheumatic diseases

Children with pediatric rheumatic diseases (PRDs) are required to comply with long-term treatment regimens that may not have immediate beneficial effects or may be required primarily to prevent further morbidity. As with other chronic disease regimens, compliance can be a significant problem that interferes with treatment efficacy and adequate clinical outcomes. This paper reviews (1) the prevalence and types of compliance problems in the management of PRDs; (2) patient/family, disease, and regimen factors that may be associated with treatment noncompliance; and (3) strategies for improving compliance with regimens for PRDs.
