Treatment compliance in childhood and adolescence

Monitoring progress after lung transplantation from home-patient adherence

A paperless electronic spirometer/diary instrument has been employed in a home monitoring programme for lung and heart-lung transplant patients at the University of Minnesota. The monitoring programme is part of a long term study to develop a system which will detect the earliest signs of developing rejection or infection in the transplanted organs. It is based on patient daily self-measurements of standard spirometry, vital signs, and symptoms recorded at home and transmitted weekly to the study data center over the telephone using a modern built into the instrument. This report summarizes adherence behaviour for 41 subjects enrolled in the study over a 12 month period. The number of subjects from whom home data has been received each week was used to measure adherence at the subject level. The number of records received each week measured adherence at the daily recording level. A data record consists of a daily set of spirometry, vital signs, and symptom values from a given subject. Approximately 82% of subjects transmitted records each week, over the 52 week review period. There was an average of 4.5 records received each week from each subject. Transmitted records had missing vital sign or symptom items in less than 2% of cases, spirometry data was always present. This evaluation showed than lung transplant recipients are willing and able to use a home-monitoring instrument, and that basic spirometry, data entry, and data transmission can be performed satisfactorily.

Compliance problems in paediatric atopic eczema

Compliance problems are a common cause of apparent treatment failure in atopic eczema. The results of a survey of parents with children attending dermatologists for atopic eczema is presented. Major reasons for failure to comply include a poor understanding of the chronic nature of the disease, a fear of topical corticosteroids, the belief that atopic eczema is due to an allergy, and the time and cost of treatment. The explanation that treatment is a control and not a cure is also important in the parent's perception of treatment results. Suggested solutions to some of these points are discussed.

Methotrexate therapy for ectopic pregnancy in adolescents

STUDY OBJECTIVE

To determine the suitability and efficacy of methotrexate (MTX) therapy for adolescent patients with ectopic pregnancy.

MATERIALS

Patients with ectopic pregnancy were treated with methotrexate, 50 mg/m2 intramuscularly. Follow-up determinations of quantitative beta hCG levels were done on days 1, 4, and 7. They were then seen weekly until beta hCG levels were less than 15 mIU/ml.

PARTICIPANTS

Adolescents with ectopic pregnancy (55 patients) received MTX therapy and comprised the study group. They were compared with 186 adults similarly treated. The groups were compared for treatment outcome and for compliance with the rigid protocol requirements.

MAIN OUTCOME MEASURES

Treatment success was defined as a patient who required no surgical intervention and whose beta hCG levels declined to < 15 mIU/ml.

RESULTS

85% of patients required no surgical intervention following MTX injection. Surgical intervention rates were slightly higher and success rates slightly lower for adolescent patients, but these differences were not statistically significant (p = .71). Although adult patients were more likely to have a perfect compliance rating, comparison of all compliance categories showed no significant differences (p = .17).

CONCLUSIONS

MTX therapy is satisfactory for adolescent patients. It is effective, and adolescent patients are able to comply with the requirements of a rigid protocol.

[Therapeutic compliance in adolescents with chronic disease]

In clinical practice, non-compliance is an often unrecognised or frustrating reality, which physicians find difficult to accept or deal with. Possible determinants of adolescents' level of compliance may be divided into demographic factors, patient and family characteristics, aspects of the illness and treatment regimen, and quality of the patient-doctor relationship. Compliance should be viewed as a reflexion of the experience of chronic illness as well as the expression of specific adolescent developmental issues. Practical guidelines are proposed.

Supraventricular tachyarrhythmias. Pharmacologic versus nonpharmacologic approaches

Nonpharmacologic approaches to the long-term management of SVTs have evolved rapidly and now offer to patients a safe, effective alternative for symptomatic relief from many SVTs. By far, radiofrequency catheter ablation, a technology less than 10 years old, offers the least invasive and most cost-effective nonpharmacologic alternative for many SVTs. Knowledge gained through electrophysiologic and ablation studies has enlarged the understanding of SVTs and may enable electrophysiologists to approach the more common and morbid condition of atrial fibrillation. From a societal standpoint, catheter ablation can remain a cost-effective mode of treatment if patient selection is stringent. The next 10 years should see further refinement in technique and in understanding of SVTs, improved technology, and enlarging applications of radiofrequency energy to cure or modify cardiac arrhythmias.

Adherence to recommended medical regimens in childhood and adolescence

OBJECTIVE

Factors that appear to influence treatment adherence among adults have been the focus of considerable research in recent years. However, less research has focused on children's treatment adherence. This paper reviews current knowledge about factors that appear to influence adherence among children and adolescents.

METHODOLOGY

Factors associated with adherence to medical regimens reviewed here include: (i) the psychosocial characteristics of children and their parents; (ii) the nature of the treatment regimen; and (iii) the relationship between health practitioners, parents and paediatric patients.

CONCLUSIONS

Issues for future research include: (i) the adherence of both children and their parents to children's treatment, and the allocation of responsibility for treatment adherence; (ii) the wide range of behaviours involved in regimen adherence should be acknowledge; patients' adherence to one aspect of their regimen should not be considered indicative of their overall adherence; and (iii) longitudinal studies are required to examine the causal relations between patient adherence and its antecedents.
