简要总结
The study plans to learn if sending different text messages, serving as reminders or encouragement, may help patients take their medication more often if they have had trouble keeping up with their medicines.
详细描述
Background: Up to fifty percent of patients do not take their cardiovascular medications as prescribed resulting in increased morbidity, mortality, and healthcare costs. Mobile and digital technologies for health promotion and disease self-management offer an intriguing and as of yet untested opportunity to adapt behavioral 'nudges' using ubiquitous cell phone technology to facilitate medication adherence.
Objectives: Aim 1: Conduct a pragmatic patient-level randomized intervention across three health care systems (HCS) to improve adherence to chronic CV medications. The primary outcome will be medication adherence defined by the proportion of days covered (PDC) using pharmacy refill data. Secondary outcomes include clinical events (e.g., event times for stroke, MI, mortality), utilization of care (e.g., hospitalizations or clinic visits for CV-related reasons), and costs of healthcare utilization. Aim 2: Evaluate the intervention using a mixed methods approach and applying the RE-AIM (reach, effectiveness, adoption, implementation, and maintenance) framework. In addition, assess the context and implementation processes to inform local tailoring, adaptations and modifications, and eventual expansion of the intervention within the 3 HCS more broadly and nationally.
Setting: The study will be conducted within three HCS in metro Denver: VA Eastern Colorado Health Care System (VA), Denver Health and Hospital Authority, and UCHealth.

结局指标
主要结局
Medication Adherence
时间窗: 12 months after intervention
The primary outcome was medication adherence defined by the proportion of days covered (PDC) using pharmacy refill data adjusted difference from usual care.
Mean Proportion of Days Covered Relative to Usual Care
时间窗: 12 months
We analyzed this longitudinal data (up to 12 observations per patient) and estimated absolute differences in PDC between treatment arms and usual care using a Generalized Estimating Equation (GEE) model with an identity link and independence with unequal variances for the covariance structure of the 12 observations .A multistage gatekeeper approach was used to account for multiple treatment comparisons by comparing each of the 3 treatment arms to the control in stage 1 using significance levels of 0.05/3, and if any test was significant, a significance level of (R/3)\*(0.05/3) using the Holm method was used for the 3 pairwise comparisons, where R is the number of significant stage 1 tests.
次要结局
- Hospitalization(one year)
- Death(one year)
- Emergency Department Visit(one year)
