Abstract
Introduction
Shared decision making (SDM) involves clinicians and patients together evaluating evidence of intervention risks and benefits, considering patients’ preferences, goals, values, and concerns, and arriving at a decision.1,2 Interventions to promote SDM, such as patient decision aids (DAs), have been developed and tested, particularly for elective surgery, cancer screening, and other preference sensitive decisions.3–5 Research shows that patient access to an evidence-based DA during decision making improves patient experiences, enhances informed consent, and can eliminate unwanted treatment. 3 Despite the utility of many DAs, an “implementation gap” exists between their development and uptake in practice. 6 A sizable literature, including three systematic reviews,7–9 has identified key barriers to implementing DAs in real-world contexts, namely, time constraints and a lack of applicability to patient characteristics and clinical situations, lack of physician training, physicians’ reluctance to utilize SDM, and lack of a supportive clinic culture. Previous research has shown that effective implementation strategies to move beyond these “many barriers” include making DA use “routine,” involving other members of the clinical team in delivering DAs,9,10 and identifying the complex interactions of structural and cultural influences on how and why DAs become routinely embedded in health care settings.8,11,12
At the intersection of these factors are individual actors responding in ways that are so far not well understood.9,13 There is a need for sustainable incentives for individuals to engage in adoption and use of a DA, but it should also be recognized that even successful behavioral changes can disappear once incentives are removed. 14 To counter this, Elwyn and collegues 9 argue that implementation methods must incorporate better understandings of what motivates individuals to use DAs in practice.
Application of Existing Implementation Frameworks in Research on Patient Decision Aids
Current implementation science frameworks have so far had little success in tackling the enduring challenges to successful implementation outlined above. While models like the Behavior Change Wheel,

Furthermore, many existing intervention functions operate in an “outside-in” fashion. Intervention tools such as “education,”“training,” and “persuasion” are mechanisms of an
Behavioral Economics and Nudges
A potentially more effective and sustainable approach to implementation of SDM programs comes from a growing literature on “nudging.” According to Thaler and Sunstein, 24 nudges are choices and strategies for presenting them in ways that alter people’s behavior in predictable ways without forbidding options or significantly changing economic incentives. Nudges target automatic thinking processes in ways that are sometimes outside of conscious awareness but can be influential for long-term behavioral changes. 25 While nudging has been effectively used by governments to influence population health- and environment-related behaviors,26,27 it has not been widely applied in implementation research.
We propose applying the MINDSPACE behavior change toolkit to target behavior change (in this case, use of SDM and DAs) in the implementation context. MINDSPACE builds on decades of empirical findings from behavioral economics about factors that are most influential in bringing about positive behavioral changes and explicitly focuses on automatic or context-based drivers of behavior. This approach is based on a robust literature demonstrating that actors do not always respond in “rational” ways to information intended to influence their behaviors. Instead, influencing the automatic system via altering contextual influences may be more long-lasting and cost-effective than relying exclusively on information-based interventions.
28
The toolkit contains nine noncoercive influences, including
Why Nudge?
Expanding on this rationale, we chose a nudging approach targeted at clinician stakeholders for two main reasons. First, implementing a DA requires physicians and clinic staff to do more than simply “hand out” the DA to patients and caregivers. To implement with fidelity and efficacy, clinicians and staff must review it with patients in a context supportive of SDM entailing significant buy-in and motivation among clinicians and staff. 29 Enhancing these two crucial elements may be more effectively accomplished using intervention tools that operate on automatic rather than reflective thought processes, as the former have been shown to have more lasting effects on behavior change. 30
Second, given that it is not always realistically feasible to provide continuous, short-term (e.g., monetary) incentives to sustain actors’ motivations, nor to institute large-scale changes to organizational structures that would promote use of DAs, our “best shot” at changing physicians’ and clinic staff members’ long-term engagement is to try to positively affect their motivations for using a DA. The MINDSPACE tools allow implementers to initiate small attitudinal, emotional, or behavioral responses that can collectively help bring about lasting, positive behavioral change.
This article aims to describe how we used the MINDSPACE approach with clinicians to implement a validated DA for left ventricular assist device (LVAD) therapy for advanced heart failure (www.lvaddecisionaid.com).31–33 We offer concrete examples of how we applied MINDSPACE tools to systematically identify and act upon clinician stakeholder motivations to accept, use, and integrate our DA into standard clinical care. Based on these experiences, we make concrete recommendations for other researchers seeking to generalize these strategies to other implementation projects in different fields and settings.
Methods
Description of Implementation Project and Data Sources
Our current project involves implementing a validated DA for LVAD 34 with goals to 1) build capacity with key clinicians (physicians and LVAD nurse coordinators) to implement the DA through an initial “Capacity Building Webinar” 35 and reinforcement sessions; 2) collaborate with “physician champions” to support LVAD nurse coordinators in their efforts to implement the DA during patient education and to use the DA themselves; and 3) provide ongoing support to LVAD coordinators to facilitate development of sustainable practices for long-term DA use in their programs. The implementation setting includes nine US hospitals, including five that participated in our original randomized controlled trial (RCT) of the DA and four that had no prior experience with the LVAD DA. None of the nine sites were actively using the DA at the beginning of the dissemination and implementation (D&I) project due to staff turnover since the RCT. We engaged LVAD nurse coordinators as primary staff to disseminate and review the DA with patients. Coordinators generally provide LVAD education and have frequent contact with patient candidates during LVAD evaluation.
Evaluation of D&I progress and success is based on the RE-AIM framework (reach, effectiveness, adoption, implementation, maintenance), 36 tracking outcomes using an “Implementation Tracking Sheet” (ITS) that allowed us to calculate “reach” (proportion of eligible patients receiving the DA) and thereby monitor basic changes in DA use after implementing MINDSPACE approaches. The ITS also measured other aspects of RE-AIM, specifically “effectiveness” (i.e., amount of DA viewed: none, some, all) as well as fidelity (“implementation,” in the language of RE-AIM) to the intended use of our DA in the context of SDM, using a 10-item measure. The two remaining RE-AIM variables, acceptance and maintenance, were not outcome targets for the purposes of this article. We employed MINDSPACE strategies throughout our interactions with key staff engaged in implementation, most commonly in monthly phone conversations (site-specific and cross-site, as appropriate) to elicit feedback and collaboratively troubleshoot challenges, and occasionally in on-site visits.
We documented these strategies and interactions in detailed process notes of all interactions with key staff (

How We Used MINDSPACE to Motivate Use of a DA Intervention
Messenger
Research tells us that individuals are more likely to act on information if experts and other influential individuals deliver it.39–41 We expected that coordinators would be more motivated to use the DA if they receive encouragement and support from a supervising “physician champion” at each site.

Incentives
Research shows that the type, magnitude, and timing42,43 of incentives matter and that individuals are motivated more by avoiding loss (e.g., of resources or power) than by being rewarded with gains.22,44,45 In our case, we recognized that the institution of new approaches to education could potentially be interpreted by coordinators as a disincentivizing loss of independence and self-direction in one’s daily work activities. To counter this perception and to incentivize DA use, we sought to
The literature also shows that certain types of gains—for example, monetary gains—can disincentivize or “cheapen” desired behaviors that may be linked to more intrinsic motivations such as altruism or self-determination.46,47 We found this to be true among our coordinators, who say that their fundamental motivation to use the DA stems from a desire to help patients make informed decisions. Thus, our second use of “incentives” was

A substantial literature demonstrates that people are likely to do what others around are already doing.39,48,49 Given the powerful influence of norms on behavior, we sought to
Defaults
Research shows that individuals behave in ways that are convenient and are often resistant to change.52,53 Individuals often align with preselected options, or a “status quo” that does not require them to make active choices. For this reason, strategies for behavior change often include “opt-out” instead of “opt-in” approaches.54,55 In our case, we observed attachment to the status quo in that some coordinators were more willing than others to integrate the DA with educational materials (“standard education”). To counter resistance to change, we worked to

Ego
A vast literature shows that we act in ways that make us feel better about ourselves and engage in behavior that we think will give us a positive image in the eyes of important others, as well as build personal sense of self-efficacy and self-esteem.65,66 One aspect of this “ego-building” strategy was to create a subtle (and, we hope, innocuous) sense of competition between sites (see also “Norms” above). We did so by conveying site-specific reach statistics during quarterly calls with individual sites, letting each site know their “rank” in comparison to other sites, which remained anonymous. This had the effect of motivating top-performers to take active steps to maintain their identity as top performers and motivating lower performers to “get up to speed” with what they perceived as normative reach levels. This ego-drive to “beat” other sites’ reach numbers served to bring the DA into more patients’ hands.
Research also suggests we prefer to view ourselves as self-consistent,

and are likely to change our behaviors to match what we say or believe or to change our beliefs to fit our behaviors.

Preliminary Associations With RE-AIM Outcomes
During the first 6 months of implementation, 171 DAs were distributed among 433 LVAD candidates across nine D&I sites (range among individual sites: 6–53 DAs). The average reach for all sites over 6 months was 39.5% with a range of 10.9% to 94.1% among individual sites. Overall reach increased from 9.8% in the first month of implementation to 70.0% in the last month of quarter 1 (Figure 1). Larger increases in reach were observed during the time period of the post-webinar reinforcement sessions and first structured coordinator follow-up calls in which strategically employed site-specific configurations of the MINDSPACE tools were used to troubleshoot and maintain clinicians’ motivation to use the DA. We did not observe any upward trends in our other two relevant RE-AIM variables, namely, effectiveness (amount viewed) and implementation (fidelity).

Discussion
At the recent 10th Annual International Shared Decision Making conference in July 2019, a number of implementation scientists voiced an eagerness for concrete, evidence-based tools to influence behaviors targeted by their interventions. They lamented that effective decision support tools rarely make their way into real-world clinical use. Their enduring search for new implementation techniques suggests either a lack of widespread awareness of existing implementation frameworks or persistent gaps in their perceived utility. We believe that the MINDSPACE toolkit helps fill this gap by offering nine evidence-based tools from behavioral economics to enact change in behavior in ways demonstrated to be effective, low-cost, and sustainable. In an effort to facilitate generalizability, we offer recommendations (Table 3) for implementation scientists seeking to apply these tools in their own implementation projects.
Recommendations for Applications of MINDSPACE in Implementation Science
In applying MINDSPACE to motivate pro-implementation behaviors among key participating clinic staff, we respond to calls by Elwyn and collegues 9 to address two understudied stages that precede “acceptance” in the “Five Stages of Achieved Implementation” model,71,72 now widely used in implementation research. These two preliminary stages include “orientation” (awareness and interest in innovation) and “insight” (understanding impacts of an implementation for existing routines). Despite their importance for framing and motivating behavior, little is known about how to shape orientation and insight in ways that lead to positive and sustainable behavioral change. Through our use of MINDSPACE’s evidence-based strategies, we have taken active steps to 1) enhance awareness and interest (“orientation”) among key actors involved in implementation activities and 2) situate our DA as a new default centerpiece in patient education while monitoring its impacts on existing routines (“insight”) through constant feedback from coordinators and physicians actively using the DA in practice. We believe that these two elements correspond to the two “peaks” in our “reach” timeline (Figure 1) whereby an initial “Capacity Building Webinar” and reinforcement sessions helped generate awareness and interest, while Feedback and Troubleshooting sessions were used to collaboratively gain insight into the impacts of our newly implemented DA on clinic routines, coordinator and physician roles, and patient experiences.
Using MINDSPACE in a Context of Limited Resources for Implementation
An additional advantage of the MINDSPACE toolkit is that it

argue that while surface-level effects may seem fleeting, such behaviors and decisions may translate into longer lasting changes. These effects may better be thought of as self-sustaining “triggers.” While we agree with this in principle, we also suspect that some triggers may need reinforcement, and (in our experience) encouragement from implementers to build in reinforcements that sustain initial nudging effects. We believe this is illustrated by the effects shown in Figure 1. Notably, we did not see similar upward trends in other RE-AIM variables including implementation (fidelity) and effectiveness (amount of DA viewed). This suggest that 1) we may have focused our MINDSPACE messaging narrowly on increasing reach rather than on enhancing the breadth and/or fidelity of using the DA; or 2) the MINDSPACE tools may be better equipped to enact broad changes in use rather than in the subtleties of
Second, Michie et al. 15 argue that MINDSPACE does not appear to encompass all the important intervention types. We believe that the enduring focus of those who wish to use MINDSPACE should be on its utility, not necessarily on how exhaustive the range of its influences is. The tools represent major categories of influence in behavioral economics but do not encompass all possible modes of influence over human behavior.
A third concern is generalizability across contexts and across populations. Individuals’ responses to nudges are likely to differ across institutional, social, economic, and cultural contexts. 73 We found that formative research with key informants from the target population (LVAD patients, physicians, and clinical staff) significantly helped us identify relevant motivations and tailor the MINDSPACE strategies accordingly.
Conclusion
MINDSPACE tools show great promise for bringing innovative research from behavioral economics into the realm of implementation science with the aim of effecting positive behavioral change. In this article, we have provided recommendations for how these tools can be adapted to an implementation context to help close the “implementation gap” by encouraging uptake of an evidence-based patient DA in real-world contexts. MINDSPACE helps address the enduring challenges of implementation by offering concrete solutions to influence individual motivations for engaging in positive behaviors targeted during implementation. Our preliminary results illustrate the promise of this approach, though further research is needed to better understand the impacts of distinct nudging approaches in the MINDSPACE toolkit in other implementation contexts.
