Interventions to Enhance Patient Adherence to Medication Prescriptions: Scientific Review

McDonald, Heather P., Garg, Amit X., Haynes, R. Brian·2002·JAMA

Abstract

CONTEXT: Low adherence with prescribed treatments is ubiquitous and undermines treatment benefits. OBJECTIVE: To systematically review published randomized controlled trials (RCTs) of interventions to assist patients' adherence to prescribed medications. DATA SOURCES: A search of MEDLINE, CINAHL, PSYCHLIT, SOCIOFILE, IPA, EMBASE, The Cochrane Library databases, and bibliographies was performed for records from 1967 through August 2001 to identify relevant articles of all RCTs of interventions intended to improve adherence to self-administered medications. STUDY SELECTION AND DATA EXTRACTION: Studies were included if they reported an unconfounded RCT of an intervention to improve adherence with prescribed medications for a medical or psychiatric disorder; both adherence and treatment outcome were measured; follow-up of at least 80% of each study group was reported; and the duration of follow-up for studies with positive initial findings was at least 6 months. Information on study design features, interventions, controls, and findings (adherence rates and patient outcomes) were extracted for each article. DATA SYNTHESIS: Studies were too disparate to warrant meta-analysis. Forty-nine percent of the interventions tested (19 of 39 in 33 studies) were associated with statistically significant increases in medication adherence and only 17 reported statistically significant improvements in treatment outcomes. Almost all the interventions that were effective for long-term care were complex, including combinations of more convenient care, information, counseling, reminders, self-monitoring, reinforcement, family therapy, and other forms of additional supervision or attention. Even the most effective interventions had modest effects. CONCLUSIONS: Current methods of improving medication adherence for chronic health problems are mostly complex, labor-intensive, and not predictably effective. The full benefits of medications cannot be realized at currently achievable levels of adherence; therefore, more studies of innovative approaches to assist patients to follow prescriptions for medications are needed.

Claims the paper makes

This paper’s full text isn’t openly available, so its claims and self-check weren’t run. The registry and citation checks still apply.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Other reviews found that about half of interventions significantly improved adherence in chronic conditions, medication prescriptions, and self-administered medications.

    “The finding that none of the interventions were effective at increasing adherence is at odds with other literature reviews (not focusing on hormonal therapy) that found approximately half of interventions significantly enhanced adherence in the context of chronic conditions,30 medication prescriptions in general,31 and self-administered medications for chronic diseases.32”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
