Limits of confidence in tracer compounds as a means of measuring patient compliance with medication

Mobile technology for medication adherence in people with mood disorders: A systematic review

BACKGROUND

Medication non-adherence is a critical challenge for many patients diagnosed with mood disorders (Goodwin and Jamison, 1990). There is a need for alternative strategies that improve adherence among patients with mood disorders that are cost-effective, able to reach large patient populations, easy to implement, and that allow for communication with patients outside of in-person visits. Technology-based approaches to promote medication adherence are increasingly being explored to address this need. The aim of this paper is to provide a systematic review of the use of mobile technologies to improve medication adherence in patients with mood disorders.

METHODS

A total of nine articles were identified as describing mobile technology targeting medication adherence in mood disorder populations.

RESULTS

Results showed overall satisfaction and feasibility of mobile technology, and reduction in mood symptoms; however, few examined effectiveness of mobile technology improving medication adherence through randomized control trials.

LIMITATIONS

Given the limited number of studies, further research is needed to determine long term effectiveness.

CONCLUSIONS

Mobile technologies has the potential to improve medication adherence and can be further utilized for symptom tracking, side effects tracking, direct links to prescription refills, and provide patients with greater ownership over their treatment progress.

Measurement of psychiatric treatment adherence

OBJECTIVE

Nonadherence to medications for mental disorders substantially limits treatment effectiveness and results in higher rates of relapse, hospitalization, and disability. Accurate measurement of medication adherence is important not only in adherence research but also in clinical trials in which medications are being evaluated and in clinical practice where failure to detect nonadherence results in premature medication changes, unnecessary polypharmacy, and greater likelihoods of functional deteriorations and hospitalizations. This is a review of psychiatric treatment adherence methods and measures arising from a meeting on "Methodological Challenges in Psychiatric Treatment Adherence Research" held on September 27-28, 2007, in Bethesda, MD, and organized by the National Institute of Mental Health (NIMH).

METHODS

This paper reviews the range of modalities currently available for assessing adherence behavior including pill counts, pharmacy records, technology-assisted monitoring, biological assays, and a range of self-report and interviewer-rated scales. Measures of adherence attitudes are also reviewed.

RESULTS

Each of the adherence measures described are imperfect estimates of actual medication ingestion, but each provides informative estimates of adherence or the attitudinal factors associated with adherence. Measure selection depends on a range of factors including the patient sample, the context in which the measure is being used, and the clinical outcomes expected from various levels of nonadherence. The use of multiple measures of adherence is encouraged to balance the limitations of individual measures.

CONCLUSION

While adherence assessment has become increasingly sophisticated in recent years, there remains a need for refinement and expansion on currently available methods and measures.
