Investigating the complementary value of discrete choice experiments for the evaluation of barriers and facilitators in implementation research: a questionnaire survey

Abstract

Background: The potential barriers and facilitators to change should guide the choice of implementation strategy. Implementation researchers believe that existing methods for the evaluation of potential barriers and facilitators are not satisfactory. Discrete choice experiments (DCE) are relatively new in the health care sector to investigate preferences, and may be of value in the field of implementation research. The objective of our study was to investigate the complementary value of DCE for the evaluation of barriers and facilitators in implementation research.

Preferences for street configuration and street tree planting in urban Hong Kong

“…This is considered to be acceptable given the complexity of the choice experiment, and the similarity in response rates achieved in other studies using discrete choice experiments ( Van der Pol and Cairns, 2001;Dia, 2002;Ratcliffe et al, 2009;Van Helvoort-Postulart et al, 2009;Chau et al, 2010). Of the 533 interviews, 509 interviewees provided sufficient information for analysis.…”

Preferences for Health Interventions: Improving Uptake, Adherence, and Efficiency

“…By focusing on patient preferences and trade-offs using an experimental approach, systematically designed stated preference surveys may reduce social desirability and other biases that are often seen with more direct questioning [5]. (For example: patients may be reluctant to indicate that they would have preferred less interaction with a counselor; or they might mark all in a series of intervention characteristics as ‘very important.’) Finally, HPR can complement implementation science when used as a diagnostic tool to identify barriers to and facilitators of treatment engagement as well as to help policymakers and clinicians customize interventions and communication strategies in new settings [6,7]. …”

Facilitating the implementation of pharmacokinetic‐guided dosing of prophylaxis in haemophilia care by discrete choice experiment

“…Within a DCE, it is possible to consider both health and non‐health outcomes simultaneously . As the study population must choose between different options and make trade‐offs between several attributes and their levels, DCE can be used as a diagnostic tool to prioritize potential barriers and facilitators and to specify implementation strategies . To assess the internal consistency of responses, a rationality test was added consisting of a choice set where one of the two options was clearly superior at all levels.…”

“…Attributes and attribute levels for pharmacokinetic (PK)-guided dosing of prophylaxis with factor concentrate compared to current treatment. be used as a diagnostic tool to prioritize potential barriers and facilitators and to specify implementation strategies [10,21,22]. To assess the internal consistency of responses, a rationality test was added consisting of a choice set where one of the two options was clearly superior at all levels.…”

“…Although six prior DCE studies have been performed in haemophilia patients [13][14][15][16][17][18], none have been performed on preferences with regard to PKguided dosing of prophylaxis. Literature in other diseases demonstrates that DCE is a valuable method to tailor implementation strategies to specify barriers and facilitators in an implementation process [21,34,35]. Table 3.…”
