Efficient methods for screening populations for undiagnosed atrial fibrillation (AF) are needed to reduce its associated mortality, morbidity, and costs. The use of digital technologies, including wearable sensors and large health record data sets allowing for targeted outreach toward individuals at increased risk for AF, might allow for unprecedented opportunities for effective, economical screening. The trial's primary objective is to determine, in a real-world setting, whether using wearable sensors in a risk-targeted screening population can diagnose asymptomatic AF more effectively than routine care. Additional key objectives include (1) exploring 2 rhythm-monitoring strategies-electrocardiogram-based and exploratory pulse wave-based-for detection of new AF, and (2) comparing long-term clinical and resource outcomes among groups. In all, 2,100 Aetna members will be randomized 1:1 to either immediate or delayed monitoring, in which a wearable patch will capture a single-lead electrocardiogram during the first and last 2 weeks of a 4-month period beginning immediately or 4 months after enrollment, respectively. An observational, risk factor-matched control group (n = 4,000) will be developed from members who did not receive an invitation to participate. The primary end point is the incidence of new AF in the immediate- vs delayed-monitoring arms at the end of the 4-month monitoring period. Additional efficacy and safety end points will be captured at 1 and 3 years. The results of this digital medicine trial might benefit a substantial proportion of the population by helping identify and refine screening methods for undiagnosed AF.
ObjectivesThe advent of large databases, wearable technology, and novel communications methods has the potential to expand the pool of candidate research participants and offer them the flexibility and convenience of participating in remote research. However, reports of their effectiveness are sparse. We assessed the use of various forms of outreach within a nationwide randomized clinical trial being conducted entirely by remote means.MethodsCandidate participants at possibly higher risk for atrial fibrillation were identified by means of a large insurance claims database and invited to participate in the study by their insurance provider. Enrolled participants were randomly assigned to one of two groups testing a wearable sensor device for detection of the arrhythmia.ResultsOver 10 months, the various outreach methods used resulted in enrollment of 2659 participants meeting eligibility criteria. Starting with a baseline enrollment rate of 0.8% in response to an email invitation, the recruitment campaign was iteratively optimized to ultimately include website changes and the use of a five-step outreach process (three short, personalized emails and two direct mailers) that highlighted the appeal of new technology used in the study, resulting in an enrollment rate of 9.4%. Messaging that highlighted access to new technology outperformed both appeals to altruism and appeals that highlighted accessing personal health information.ConclusionsTargeted outreach, enrollment, and management of large remote clinical trials is feasible and can be improved with an iterative approach, although more work is needed to learn how to best recruit and retain potential research participants.Trial registrationClinicaltrials.govNCT02506244.

Adherence with infliximab therapy during the first year of treatment in patients with CD was associated with a shorter hospital length of stay and lower inpatient costs compared with nonadherent patients. Strategies for increasing adherence rates to infliximab maintenance therapy may be valuable in reducing hospitalizations and inpatient costs in patients with CD.
BackgroundTo assess the impact of a continuous measure of adherence with infliximab maintenance treatment in Crohn’s disease (CD) during the first year of treatment on CD-related health care utilization, CD-related hospitalizations, inpatient costs, and length of hospital stay.Patients and methodsA retrospective claims analysis using the IMS LifeLink Health Plan Claims Database (September 1, 2004, to June 30, 2009) was conducted. Continuous enrollment for 12 months before and 12 months after the index date was required. Patients were required to have at least two claims with an International Classification of Diseases, 9th Revision, Clinical Modification diagnosis code for CD (555.xx) pre-index and be aged ≥ 18 years at index. Patients with three infusions during the first 56 days post-index and at least one infusion following day 56 post-index were considered to have maintenance therapy. Adherence and nonadherence were defined as a medication possession ratio of ≥ 80% and < 80%, respectively.ResultsFour hundred forty-eight patients were included in the analysis (mean age, 42.6 years; 56% female; mean ± standard deviation [SD] and median number of infliximab infusions, 7.35 ± 1.60 and 8). The number of patients who met the definition of adherence was 344 (77%). CD-related health care utilization was not significantly impacted by adherence except for ancillary services and radiology. Fewer adherent patients were hospitalized compared with nonadherent patients (9% versus 16%; P = 0.03). Adherent patients had fewer mean ± SD and median days in the hospital (5.5 ± 3.4 and 5 days) compared with nonadherent patients (13.1 ± 14.2 and 8 days; P = 0.01). Mean ± SD and median hospital costs were significantly greater for nonadherent patients ($40,822 ± $49,238 and $28,864) compared with adherent patients ($13,704 ± $10,816 and $9938; P = 0.002).ConclusionAdherence with maintenance infliximab over 12 months was associated with lower rates of CD-related hospitalizations and inpatient costs and a shorter length of hospital stay.
BackgroundModerate to severe plaque psoriasis has a serious effect on health-related quality of life. Patients treated with biologic medications place importance on satisfaction and treatment frequency options. We assessed patient-reported treatment satisfaction and dosing frequency choice with biologics.MethodsWe used a health care claims database to identify patients with moderate to severe plaque psoriasis. Participants completed the Treatment Satisfaction Questionnaire for Medication. Results were compared between patients experienced with biologics (adalimumab, etanercept, or ustekinumab) or not (cyclosporine or methotrexate). Participants were asked for their choices of dosing options of once every 1–2 weeks, 3–4 weeks, 1–2 months, or 2–3 months. Participants were also asked for their choices of dosing options of every 1, 2, 3, and so on up to every 12+ weeks.ResultsA total of 426 patients completed the survey (263 biologic-experienced and 163 biologic-naïve patients). Patient satisfaction with psoriasis treatment was significantly higher in the biologic-experienced cohort. The most frequently chosen option (38.8% of all participating patients) was every 2–3 months; 37.3% chose once every 1–2 weeks. Significant differences were found in the percentage of biologic-naïve patients choosing 2–3-month (49.7%) over 1–2-week (20.9%) dosing (P<0.001). Among biologic-experienced patients, the difference between the percentage of patients choosing the 2–3-month (35.7%) and 1–2-week (41.8%) options was not significant (P=0.264). The two most often week-specific intervals chosen by biologic-naïve patients were 12+ weeks (42.3%) and 4 weeks (15.6%). The biologic-experienced patients most often chose 12+ weeks (31.2%) and 1 week (25.9%).ConclusionPatients using biologics reported satisfaction with their treatment, which may positively affect outcomes. Longer dosing intervals were chosen most frequently among all patients combined. Reports of patient satisfaction with prior treatments and choices regarding dosing frequency, among all other considerations, should be evaluated in determining an appropriate biologic medication for psoriasis.
