Objective

Individuals living with bipolar disorder (BD) have poorer management of chronic medical conditions such as hypertension (HTN), and worse treatment adherence than the general population. The study objective was to obtain information from patients with both BD and HTN that would inform the development of an m-Health intervention to improve medication adherence for poorly adherent individuals living with both these chronic illnesses.

Methods

Focus group methodology was used to collect information from 13 participants on perceived barriers and facilitators to BD and HTN medication adherence, as well as feedback on the demonstration and use of a bidirectional text messaging system for medication reminders. Focus groups were audiotaped, transcribed verbatim, and analyzed using content analysis with an emphasis on dominant themes.

Results

Forgetfulness was the most frequently mentioned barrier to taking antihypertensive medications, and decisions about taking them were often influenced by BD mood fluctuations and the burden of having to take "too many pills" for both chronic illnesses. Participants' feedback about the use of a text-messaging system to help with medication adherence for BD and HTN was very positive, and their suggestions for modification were incorporated into a more customized system for testing in a Phase 2 trial.

Conclusions

Our findings indicate that patient engagement in the development of an m-health intervention has the potential to improve adherence with both BD and HTN medications in individuals with known sub-optimal adherence. Patient engagement in health care is essential if we are to optimize patient outcomes.

Objective

This study evaluated the feasibility, acceptability, and preliminary efficacy of psychoeducation plus an automated text messaging intervention (Individualized Texting for Adherence Building-Cardiovascular [iTAB-CV]) to improve adherence to antihypertensives and bipolar disorder medication.

Methods

After a psychoeducation program, iTAB-CV was administered for 2 months. In month 1, participants received one educational-motivational and one mood rating text daily. In month 2, medication reminders were added.

Results

The sample (N=38) was 74% African American and 53% women, with a mean±SD age of 51.53±9.06. Antihypertensive nonadherence decreased from a mean of 43%±23% to 21%±18% at 12 weeks (χ²=34.6, df=3, p<0.001). Systolic blood pressure decreased from a mean of 144.8±15.5 mmHg to 136.0±17.8 mmHg (χ²=17.6, df=3, p<.001). Retention was 100%.

Conclusions

In this uncontrolled trial, participants were highly engaged and medication adherence and reduced systolic blood pressure were sustained after psychoeducation plus iTAB-CV. Because iTAB-CV is automated and delivered remotely, it has the potential to reach a large and challenging population.
