Abstract
OBJECTIVES Clinical trials are increasingly testing the effectiveness of paying patients' financial incentives for achieving desired clinical outcomes. Some researchers and providers are concerned that patient financial incentives will harm the doctor-patient relationship. How patients feel about these approaches, and these trials, is largely unknown. This study examined patients' perceptions of a compound behavioral and financial incentive intervention used in a large multicenter trial to lower low-density lipoprotein cholesterol (LDL-C), including their perceptions of benefits and challenges and the study's effect on patients' relationship with their primary care physicians (PCPs). STUDY DESIGN Semi-structured telephone interviews with patients post intervention. METHODS PCPs from 3 primary care practices in the northeastern United States were randomized to 1 of 4 arms: physician financial incentives, patient financial incentives, shared incentives between physicians and patients, and a control arm. Within each arm, 10 high, 10 medium, and 10 low performers in LDL-C reduction were interviewed. Interviews targeted reasons for enrolling in the study, the specific intervention elements that helped them reach the goal (incentives, engagement, monitoring), challenges faced in reducing cholesterol, and the impact of study participation on their relationship with their PCP. RESULTS Patients reported positive experiences with the study: 65% described personal changes to improve health and 61% reported increased awareness. Views about financial incentives varied: 71% clearly found them motivating and 36% claimed they made no difference. Patients noted that changing lifestyle (36%) and diet (65%) was difficult. Patients who substantially lowered their LDL-C revealed themes similar to those who did not. CONCLUSIONS Overall, behavioral interventions with financial incentives appear to be socially acceptable to patients who participate in them. Both adherence monitoring and financial incentives were well received, with little effect on the physician-patient relationship.

Abstract
Study Objectives Fatigue from sleep loss is a risk to physician and patient safety, but objective data on physician sleep and alertness on different duty hour schedules is scarce. This study objectively quantified differences in sleep duration and alertness between medical interns working extended overnight shifts and residents not or rarely working extended overnight shifts. Methods Sleep-wake activity of 137 interns and 87 PGY-2/3 residents on 2-week Internal Medicine and Oncology rotations was assessed with wrist-actigraphy. Alertness was assessed daily with a brief Psychomotor Vigilance Test (PVT) and the Karolinska Sleepiness Scale. Results Interns averaged 6.93 hours (95% confidence interval [CI] 6.84-7.03 hours) sleep per 24 hours across shifts, significantly less than residents not working overnight shifts (7.18 hours, 95% CI 7.06-7.30 hours, p = .007). Interns obtained on average 2.19 hours (95% CI 2.02-2.36 hours) sleep during on-call nights (17.5% obtained no sleep). Alertness was significantly lower on mornings after on-call nights compared to regular shifts (p < .001). Naps between 9 am and 6 pm on the first day post-call were frequent (90.8%) and averaged 2.84 hours (95% CI 2.69-3.00 hours), but interns still slept 1.66 hours less per 24 hours (95% CI 1.56-1.76 hours) compared to regular shift days (p < .001). Sleep inertia significantly affected alertness in the 60 minutes after waking on-call. Conclusions Extended overnight shifts increase the likelihood of chronic sleep restriction in interns. Reduced levels of alertness after on-call nights need to be mitigated. A systematic comparison of sleep, alertness, and safety outcomes under current and past duty hour rules is encouraged.

Abstract
Employers commonly use adjustments to health insurance premiums as incentives to encourage healthy behavior, but the effectiveness of those adjustments is controversial. We gave 197 obese participants in a workplace wellness program a weight loss goal equivalent to 5 percent of their baseline weight. They were randomly assigned to a control arm, with no financial incentive for achieving the goal, or to one of three intervention arms offering an incentive valued at $550. Two intervention arms used health insurance premium adjustments, beginning the following year (delayed) or in the first pay period after achieving the goal (immediate). A third arm used a daily lottery incentive separate from premiums. At twelve months there were no statistically significant differences in mean weight change either between the control group (whose members had a mean gain of 0.1 pound) and any of the incentive groups (delayed premium adjustment, -1.2 pound; immediate premium adjustment, -1.4 pound; daily lottery incentive, -1.0 pound) or among the intervention groups. The apparent failure of the incentives to promote weight loss suggests that employers that encourage weight reduction through workplace wellness programs should test alternatives to the conventional premium adjustment approach by using alternative incentive designs, larger incentives, or both.

Abstract
OBJECTIVES Medication adherence is often suboptimal, especially among patients on multiple chronic medications. We examined the association between synchronized medication refill schedules-which typically reduce organizational effort and logistical demands-and adherence. STUDY DESIGN Retrospective study among patients enrolled in Medicare Advantage prescription drug plans. METHODS We used 2012 pharmacy, medical, and enrollment data linked with consumer meta-data for Medicare patients filling 2 or more maintenance prescriptions for antihypertensives, lipid-lowering agents, antidiabetic agents, antidepressants, and/or antiosteoporotic agents. Medication adherence for the year was measured using the proportion of days covered (PDC) at the drug class level. Patients were deemed adherent if drug class PDC was ≥0.80. Outcomes were compared between 1:1 propensity score-matched patients on synchronized versus nonsynchronized refill schedules for maintenance medications. RESULTS The synchronized refill group showed better adherence than the control group, although the magnitude of effects varied by drug class and specific outcome measure. Mean PDC scores ranged from 0.02 higher for antihypertensives to 0.07 higher for antidepressants in the synchronized refill group relative to the control group (P <.01). Further, compared with the control group, a larger proportion of synchronized refill group members were deemed adherent, ranging from 6 percentage points higher for antihypertensives to 15 percentage points higher for lipid-lowering agents (P <.01). Differences between the synchronized and control groups were larger among exclusive users of retail versus mail order pharmacies for maintenance medications. CONCLUSIONS Synchronized medication refill schedules were associated with better medication adherence, particularly for patients filling maintenance medications exclusively at retail pharmacies.

Abstract
PURPOSE To determine if two widely used behavioral change measures-Stages of Change (SoC) and Patient Activation Measure (PAM)-correlate with each other, are affected by financial incentives, or predict positive outcomes in the context of incentive-based health interventions. DESIGN Secondary analysis of two randomized controlled trials of incentives for weight loss and for improved diabetes self-monitoring. SETTING Philadelphia, Pennsylvania; Newark, New Jersey. SUBJECTS A total of 132 obese and 75 diabetic adults enrolled in one of two trials. MEASURES . SoC and PAM scores; weight loss and usage rate of diabetes self-monitoring equipment. ANALYSIS Multiple regression; Kruskal-Wallis test. RESULTS We found no association between baseline SoC and PAM scores in either study (p = .30 and p = .89). Regression models showed no association between baseline PAM score and SoC and subsequent outcomes for either study (weight loss study: PAM: p = .14, SoC: p = .1; diabetes study: PAM: p = .45, SoC: p = .61). Change in PAM score and SoC among participants in the intervention groups did not differ by study arm or among participants with better outcomes. CONCLUSION . PAM score and SoC may not effectively predict success or monitor progress among individuals enrolled in incentive-based interventions.

Abstract
OBJECTIVES We compared the effectiveness of diabetes-focused messaging strategies at increasing enrolment in a healthy food programme among adults with diabetes. METHODS Vitality is a multifaceted wellness benefit available to members of Discovery Health, a South Africa-based health insurer. One of the largest Vitality programmes is HealthyFood (HF), an incentive-based programme designed to encourage healthier diets by providing up to 25% cashback on healthy food purchases. We randomised adults with type 2 diabetes to 1 of 5 arms: (1) control, (2) a diabetes-specific message, (3) a message with a recommendation of HF written from the perspective of a HF member with diabetes, (4) a message containing a physician's recommendation of HF, or (5) the diabetes-specific message from arm 2 paired with an 'enhanced active choice'(EAC). In an EAC, readers are asked to make an immediate choice (in this case, to enrol or not enrol); the pros and cons associated with the preferred and non-preferred options are highlighted. HF enrolment was assessed 1 month following the first emailed message. RESULTS We randomised 3906 members. After excluding those who enrolled in HF or departed from the Vitality programme before the first intervention email, 3665 (94%) were included in a modified intent-to-treat analysis. All 4 experimental arms had significantly higher HF enrolment rates compared with control (p<0.0001 for all comparisons). When comparing experimental arms, the diabetes-specific message with the EAC had a significantly higher enrolment rate (12.6%) than the diabetes-specific message alone (7.6%, p=0.0016). CONCLUSIONS Messages focused on diabetes were effective at increasing enrolment in a healthy food programme. The addition of a framed active choice to a message significantly raised enrolment rates in this population. These findings suggest that simple, low-cost interventions can enhance enrolment in health promoting programmes and also be pragmatically tested within those programmes.

Abstract
BACKGROUND Coronary artery disease is the single leading cause of death in the United States, and medications can significantly reduce the rate of repeat cardiovascular events and treatment procedures. Adherence to these medications, however, is very low. METHODS HeartStrong is a national randomized trial offering 3 innovations. First, the intervention is built on concepts from behavioral economics that we expect to enhance its effectiveness. Second, the implementation of the trial takes advantage of new technology, including wireless pill bottles and remote feedback, to substantially automate procedures. Third, the trial's design includes an enhancement of the standard randomized clinical trial that allows rapid-cycle innovation and ongoing program enhancement. RESULTS Using a system involving direct data feeds from 6 insurance partners followed by mail, telephone, and email contact, we enrolled 1,509 patients discharged from the hospital with acute myocardial infarction in a 2:1 ratio of intervention:usual care. The intervention period lasts 1 year; the primary outcome is time to first fatal or nonfatal acute vascular event or revascularization, including acute myocardial infarction, unstable angina, stroke, acute coronary syndrome admission, or death. CONCLUSIONS Our randomized controlled trial of the HeartStrong program will provide an evaluation of a state-of-the-art behavioral economic intervention with a number of important pragmatic features. These include a tailored intervention responding to patient activity, streamlining of consent and implementation processes using new technologies, outcomes centrally important to patients, and the ability to implement rapid-cycle innovation.

Abstract
PURPOSE To compare the effectiveness of different combinations of social comparison feedback and financial incentives to increase physical activity. DESIGN Randomized trial (Clinicaltrials.gov number, NCT02030080). SETTING Philadelphia, Pennsylvania. PARTICIPANTS Two hundred eighty-six adults. INTERVENTIONS Twenty-six weeks of weekly feedback on team performance compared to the 50th percentile (n = 100) or the 75th percentile (n = 64) and 13 weeks of weekly lottery-based financial incentive plus feedback on team performance compared to the 50th percentile (n = 80) or the 75th percentile (n = 44) followed by 13 weeks of only performance feedback. MEASURES Mean proportion of participant-days achieving the 7000-step goal during the 13-week intervention. ANALYSIS Generalized linear mixed models adjusting for repeated measures and clustering by team. RESULTS Compared to the 75th percentile without incentives during the intervention period, the mean proportion achieving the 7000-step goal was significantly greater for the 50th percentile with incentives group (0.45 vs 0.27, difference: 0.18, 95% confidence interval [CI]: 0.04 to 0.32; P = .012) but not for the 75th percentile with incentives group (0.38 vs 0.27, difference: 0.11, 95% CI: -0.05 to 0.27; P = .19) or the 50th percentile without incentives group (0.30 vs 0.27, difference: 0.03, 95% CI: -0.10 to 0.16; P = .67). CONCLUSION Social comparison to the 50th percentile with financial incentives was most effective for increasing physical activity.

Abstract
PURPOSE To test whether employer matching of employees' monetary contributions increases employees' (1) participation in deposit contracts to promote weight loss and (2) weight loss. DESIGN A 36-week randomized trial. SETTING Large employer in the northeast United States. PARTICIPANTS One hundred thirty-two obese employees. INTERVENTIONS Over 24 weeks, participants were asked to lose 24 pounds and randomized to monthly weigh-ins or daily weigh-ins with monthly opportunities to deposit $1 to $3 per day that was not matched, matched 1:1, or matched 2:1. Deposits and matched funds were returned to participants for each day they were below their goal weight. MEASURES Rates of making ≥1 deposit, weight loss at 24 weeks (primary outcome), and 36 weeks. ANALYSIS Deposit rates were compared using χ(2) tests. Weight loss was compared using t tests. RESULTS Among participants eligible to make deposits, 29% made ≥1 deposit and matching did not increase participation. At 24 weeks, control participants gained an average of 1.0 pound, whereas 1:1 match participants lost an average of 5.3 pounds (P = .005). After 36 weeks, control participants gained an average of 2.1 pounds, whereas no match participants lost an average of 5.1 pounds (P = .008). CONCLUSION Participation in deposit contracts to promote weight loss was low, and matching deposits did not increase participation. For deposit contracts to impact population health, ongoing participation will need to be higher.

Abstract
BACKGROUND More than half of adults in the United States do not attain the minimum recommended level of physical activity to achieve health benefits. The optimal design of financial incentives to promote physical activity is unknown. OBJECTIVE To compare the effectiveness of individual versus team-based financial incentives to increase physical activity. DESIGN Randomized, controlled trial comparing three interventions to control. PARTICIPANTS Three hundred and four adult employees from an organization in Philadelphia formed 76 four-member teams. INTERVENTIONS All participants received daily feedback on performance towards achieving a daily 7000 step goal during the intervention (weeks 1- 13) and follow-up (weeks 14- 26) periods. The control arm received no other intervention. In the three financial incentive arms, drawings were held in which one team was selected as the winner every other day during the 13-week intervention. A participant on a winning team was eligible as follows: $50 if he or she met the goal (individual incentive), $50 only if all four team members met the goal (team incentive), or $20 if he or she met the goal individually and $10 more for each of three teammates that also met the goal (combined incentive). MAIN MEASURES Mean proportion of participant-days achieving the 7000 step goal during the intervention. KEY RESULTS Compared to the control group during the intervention period, the mean proportion achieving the 7000 step goal was significantly greater for the combined incentive (0.35 vs. 0.18, difference: 0.17, 95 % confidence interval [CI]: 0.07-0.28, p <0.001) but not for the individual incentive (0.25 vs 0.18, difference: 0.08, 95 % CI: -0.02-0.18, p = 0.13) or the team incentive (0.17 vs 0.18, difference: -0.003, 95 % CI: -0.11-0.10, p = 0.96). The combined incentive arm participants also achieved the goal at significantly greater rates than the team incentive (0.35 vs. 0.17, difference: 0.18, 95 % CI: 0.08-0.28, p < 0.001), but not the individual incentive (0.35 vs. 0.25, difference: 0.10, 95 % CI: -0.001-0.19, p = 0.05). Only the combined incentive had greater mean daily steps than control (difference: 1446, 95 % CI: 448-2444, p ≤ 0.005). There were no significant differences between arms during the follow-up period (weeks 14- 26). CONCLUSIONS Financial incentives rewarded for a combination of individual and team performance were most effective for increasing physical activity. TRIAL REGISTRATION Clinicaltrials.gov identifier: NCT02001194.

Abstract
BACKGROUND Randomized clinical trials provide gold-standard evidence for the efficacy of interventions, but have limitations, including highly selected populations that make inference on effectiveness difficult and a lack of ability to adapt and change midstream. METHODS We propose two innovations for pragmatic trial design. RESULTS Evidence-based evolutionary testing, a framework that allows adaptation of interventions and rapid-cycle innovation, preserves the power of randomization while acknowledging the need for adaptation and learning. An opt-out consent framework increases the fraction of the target population who participate in trials, but may lead to dampening of effect sizes. CONCLUSION Pragmatic trials offer numerous advantages in the evaluation of behavioral interventions in health. Statistical innovations, including evidence-based evolutionary testing and opt-out framing of consent and enrollment processes, can enhance the power of pragmatic trials and lead to more rapid progress.

Abstract
INTRODUCTION Although most seriously ill Americans wish to avoid burdensome and aggressive care at the end of life, such care is often provided unless patients or family members specifically request otherwise. Advance directives (ADs) were created to provide opportunities to set limits on aggressive care near life's end. This study tests the hypothesis that redesigning ADs such that comfort-oriented care is provided as the default, rather than requiring patients to actively choose it, will promote better patient-centred outcomes. METHODS AND ANALYSIS This multicentre trial randomises seriously ill adults to receive 1 of 3 different ADs: (1) a traditional AD that requires patients to actively choose their goals of care or preferences for specific interventions (eg, feeding tube insertion) or otherwise have their care guided by their surrogates and the prevailing societal default toward aggressive care; (2) an AD that defaults to life-extending care and receipt of life-sustaining interventions, enabling patients to opt out from such care; or (3) an AD that defaults to comfort care, enabling patients to opt into life-extending care. We seek to enrol 270 patients who return complete, legally valid ADs so as to generate sufficient power to detect differences in the primary outcome of hospital-free days (days alive and not in an acute care facility). Secondary outcomes include hospital and intensive care unit admissions, costs of care, hospice usage, decision conflict and satisfaction, quality of life, concordance of preferences with care received and bereavement outcomes for surrogates of patients who die. ETHICS AND DISSEMINATION This study has been approved by the Institutional Review Boards at all trial centres, and is guided by a data safety and monitoring board and an ethics advisory board. Study results will be disseminated using methods that describe the results in ways that key stakeholders can best understand and implement. TRIAL REGISTRATION NUMBER NCT02017548; Pre-results.

Abstract
BACKGROUND Financial incentive designs to increase physical activity have not been well-examined. OBJECTIVE To test the effectiveness of 3 methods to frame financial incentives to increase physical activity among overweight and obese adults. DESIGN Randomized, controlled trial. (ClinicalTrials.gov: NCT 02030119). SETTING University of Pennsylvania. PARTICIPANTS 281 adult employees (body mass index ≥27 kg/m2). INTERVENTION 13-week intervention. Participants had a goal of 7000 steps per day and were randomly assigned to a control group with daily feedback or 1 of 3 financial incentive programs with daily feedback: a gain incentive ($1.40 given each day the goal was achieved), lottery incentive (daily eligibility [expected value approximately $1.40] if goal was achieved), or loss incentive ($42 allocated monthly upfront and $1.40 removed each day the goal was not achieved). Participants were followed for another 13 weeks with daily performance feedback but no incentives. MEASUREMENTS Primary outcome was the mean proportion of participant-days that the 7000-step goal was achieved during the intervention. Secondary outcomes included the mean proportion of participant-days achieving the goal during follow-up and the mean daily steps during intervention and follow-up. RESULTS The mean proportion of participant-days achieving the goal was 0.30 (95% CI, 0.22 to 0.37) in the control group, 0.35 (CI, 0.28 to 0.42) in the gain-incentive group, 0.36 (CI, 0.29 to 0.43) in the lottery-incentive group, and 0.45 (CI, 0.38 to 0.52) in the loss-incentive group. In adjusted analyses, only the loss-incentive group had a significantly greater mean proportion of participant-days achieving the goal than control (adjusted difference, 0.16 [CI, 0.06 to 0.26]; P = 0.001), but the adjusted difference in mean daily steps was not significant (861 [CI, 24 to 1746]; P = 0.056). During follow-up, daily steps decreased for all incentive groups and were not different from control. LIMITATION Single employer. CONCLUSION Financial incentives framed as a loss were most effective for achieving physical activity goals. PRIMARY FUNDING SOURCE National Institute on Aging.
