Background Workplaces that provide opportunities for physical activity without requiring extra time for activity could help counteract the obesity epidemic. Desk ellipticals can contribute to activity-supportive workplace environments; however, the feasibility of engaging employees in pedaling ellipticals during simultaneous office work has not been well evaluated. Objective We aim to present the rationale and methods from an ongoing randomized trial with overweight and obese employees that will evaluate (1) the effects of pedaling a compact desk elliptical on work performance and (2) the influence of different incentive types and schedules on desk pedaling quantity. Methods Overweight and obese medical center employees are being recruited in dyads for a 2 (gift card type: healthier food vs Amazon) by 3 (gift card schedule: immediate incentive contingent on individual pedaling quantity; immediate incentive partially contingent on dyads’ joint pedaling quantity; and delayed noncontingent pedaling incentive) cluster randomized within-subjects factorial trial. All participants receive a Bluetooth-enabled desk elliptical for 4 weeks and access to a mobile app that provides real-time pedaling feedback. The primary aims are to assess (1) change in employee work performance from pre- to postelliptical installation via employee and supervisor ratings and (2) effects of gift card type and schedule on quantity of objectively measured desk pedaling completed. Results Data collection is ongoing. We expect to complete main outcome analyses in 2020. Conclusions This trial represents one of the earliest attempts to assess the effects of desk pedaling and pedaling-incentive types in real-world offices. It could help bridge the research-to-practice gap by providing evidence on whether desk pedaling can be sustained without compromising work performance.

206 Background: Cancer screening, like other interventions, requires close patient-provider collaboration. By patient recall, key elements are often omitted from informed consent discussions. Most screening guideline compliance efforts focus on reducing underuse, but overuse is also harmful and may be influenced by distinct factors. Therefore, we are performing a prospective randomized trial of educational interventions to improve screening compliance for breast, cervical, colorectal, lung and prostate cancer at an urban academic medical center. Our hypothesis is that gender, age, prior screening experience, provider recommendations, anticipated benefit and distress, communication and informational support will affect compliance. Our primary data collection will be complete before the Symposium. Methods: We will enroll an age- and sex-stratified sample of 216 patients aged 40 to 89 years, 18 each treated by 12 primary care physicians at two affiliated hospitals, undergoing an annual physical examination in a cluster-randomized prospective trial of educational supports for screening. Screening guideline format (color-coding) and academic detailing will be randomly assigned independently. Patients and providers are surveyed immediately after the encounter to record their recollections of screening discussions and recommendations and their plans. Follow-up surveys at 3, 6 and 12 months assess concordance between expressed screening intentions and behaviors. Results: Pilot results indicate patient gender, age, anticipated screening-related distress and benefit, and prior screening experience affect screening recommendations and intentions. These factors vary by cancer. Patients recall less discussion than providers. Reasons not to screen are infrequently discussed. Conclusions: Cancer screening decisions are complex and vary by screening modality, patient and provider factors and communication. Improving underuse and overuse compliance may require distinct strategies. Screening overuse may be a “lower-stakes” environment to develop strategies to reduce overuse of cancer interventions of marginal or negative benefit, including treatment.
