Telephone nurse counseling for medication adherence in ulcerative colitis: a preliminary study.

OBJECTIVE

Adherence is challenging in episodic chronic conditions that require medication during both symptomatic and quiescent periods, such as ulcerative colitis (UC). Adherence for these conditions is under-studied. This study was a preliminary test of telephone nurse counseling to address cognitive and emotional barriers to adherence in UC.

METHODS

524 people taking mesalamine for UC were referred by their health care providers, and 278 (53%) enrolled. There were no demographic differences between program participants and nonparticipants. Participants reported multiple comorbidities and concomitant medications. All participants received telephone follow-up (M = 2.1 calls) from a registered nurse who used cognitive-behavioral and motivational interviewing counseling techniques. Adherence measured by structured interview was compared to a population baseline using a binomial test.

RESULTS

Attrition was 51% over 6 months but was unrelated to adherence. Participants had better adherence than the expected population rate, with a significant dose-response effect. Reasons for nonadherence were primarily psychological or efficacy-related.

CONCLUSION

Adherence following intervention was better than typical mesalamine adherence. Self-efficacy predicted adherence, but demographic and clinical variables did not. Adherent participants reported more adverse events.

PRACTICE IMPLICATIONS

Attention to patients' cognitive and emotional reactions may help to improve adherence in episodic chronic diseases such as UC.
