Insights

Medication reminder apps for coronary heart disease (CHD) patients were found to be useful and well-accepted. Young male patients with CHD were more likely to use these apps, which improved medication adherence.

Area of Science:

  • Digital health interventions
  • Cardiovascular disease management
  • Medication adherence research

Background:

  • Improving medication adherence is crucial for managing Coronary Heart Disease (CHD).
  • Mobile applications offer a potential tool to enhance adherence.
  • The MEDication reminder APPlications (MedApp-CHD) study evaluated app-based interventions for CHD patients.

Purpose of the Study:

  • To assess the reach, acceptability, utility, and engagement of medication reminder apps in the MedApp-CHD study.
  • To understand patient experiences with digital tools for medication adherence.
  • To identify key features that promote app usage and adherence in CHD patients.

Main Methods:

  • A mixed-methods approach was employed in the randomized clinical trial.
  • Data collected from patient screening logs, three-month follow-up questionnaires, focus groups, and app software analytics.
  • 163 CHD patients were randomized into usual care, basic app, or advanced app groups.

Main Results:

  • High completion rates for feedback questionnaires (94%) and focus group participation.
  • Participants found apps useful for medication reminders and accessible medication lists.
  • Apps were likely to be continued post-study and recommended to others.
  • Clinical measurement features were useful for tracking blood pressure and glucose, particularly for those with diabetes/hypertension.
  • Medication-related features were used more than clinical measurement features.
  • Lack of suitable smartphones was a primary exclusion reason, particularly among older females.

Conclusions:

  • Medication reminder apps are well-accepted and useful for improving medication adherence in CHD patients.
  • Younger male patients with CHD show higher engagement with these apps.
  • Key app features include timely reminders and accessible medication lists.
  • Future digital health interventions should consider smartphone accessibility and user demographics.

Rheumatic Heart Disease III: Medical Management

Rheumatic heart disease (RHD) management can be divided into two main strategies: prevention and long-term management.Primary PreventionPrimary prevention focuses on timely diagnosis and management of group A streptococcal pharyngitis to prevent acute rheumatic fever. The most widely used antibiotic for treating this condition is intramuscular benzathine penicillin G.Acute Rheumatic Fever TreatmentThe primary treatment goal for a patient diagnosed with acute rheumatic fever is to suppress the...

Heart Failure IV: Classification and Diagnostic Evaluation

Heart failure can be classified in various ways, with the most common classifications based on physical activity limitations, disease progression, severity, and treatment strategies.The Functional Classification of Heart Failure divides patients into four categories based on physical activity limitation due to symptom burden.Class I: Patients in this class have cardiac disease but no physical activity limitations. Ordinary activities like walking, climbing stairs, or routine tasks do not cause...

Self-Evaluation: Self-Enhancement and Self-Verification

Social psychologists have documented that feeling good about ourselves and maintaining positive self-esteem is a powerful motivator of human behavior (Tavris & Aronson, 2008). In the United States, members of the predominant culture typically think very highly of themselves and view themselves as good people who are above average on many desirable traits (Ehrlinger, Gilovich, & Ross, 2005). Often, our behavior, attitudes, and beliefs are affected when we experience a threat to our...
