Development & Testing of a Decision Aid for LVAD Placement (VADDA)

February 14, 2019 updated by: Jennifer Blumenthal-Barby, Baylor College of Medicine

Development and User Testing of a Decision Aid for Left Ventricular Assist Device (LVAD) Placement

The goal of this project is to develop a patient-centered decision aid for decision-making about end-stage heart failure treatment. This study seeks to create a decision aid that presents outcomes, risks, projected experiences, and uncertainties about Left Ventricular Assist Device (LVAD) placement to help patients make values-based decisions about placement. The investigators propose a mixed methods design involving a literature search of clinical evidence, semi-structured patient interviews, and quantitative data from a multi-site trial of patients receiving the decision aid compared to patients not receiving the aid.

  • Primary Purpose: Supportive Care
  • Allocation: Randomized
  • Interventional Model: Parallel Assignment
  • Masking: Single

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Active Comparator: LVAD Decision Aid
Decision aid presented to subjects was developed from patient and clinician feedback to increase patient knowledge on the risks, benefits, misconceptions or mispredictions regarding LVADs to help patients make an informed decision on accepting or declining LVAD placement.

Decision aids are interventions or tools designed to facilitate shared decision making and patient participation in health care decisions.

This Decision Aid was designed to discuss treatment options for patients in end-stage heart failure (i.e LVAD PLACEMENT, PALLIATIVE and SUPPORTIVE CARE).

No Intervention: No LVAD Decision Aid
The standard education processis institution-specific and unstandardized. The education consists of viewing education pamphlets that are created by device manufacturers. The traditional informed consent process may also include viewing and manipulating the actual device and meeting a patient with a device already implanted. Additionally, the LVAD coordinator describes the device and answers any questions LVAD candidates have.

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Left Ventricular Assist Device (LVAD) Knowledge Scale
Time Frame: Baseline
Questionnaire measuring subject's knowledge about Left Ventricular Assist Device therapy. Knowledge is reported on a scale from 1-100, with higher scores indicating greater knowledge. At Baseline, this scale measures LVAD knowledge before patients receive any formal education (from their LVAD coordinators and/or physicians) about LVAD therapy.
Baseline
Left Ventricular Assist Device (LVAD) Knowledge Scale
Time Frame: 1-Week Follow-up
Questionnaire measuring subject's knowledge about Left Ventricular Assist Device therapy. Knowledge is reported on a scale from 1-100, with higher scores indicating greater knowledge. At this time-point, the scale measures LVAD knowledge at 1 week following both formal education (from the clinic) as well as from our decision aid about LVAD therapy.
1-Week Follow-up
Left Ventricular Assist Device (LVAD) Knowledge Scale
Time Frame: 1-Month Follow-up
Questionnaire measuring subject's knowledge about Left Ventricular Assist Device therapy. Knowledge is reported on a scale from 1-100, with higher scores indicating greater knowledge. At this time-point, the scale measures LVAD knowledge at 1 month following both formal education (from the clinic) as well as from our decision aid about LVAD therapy.
1-Month Follow-up

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Decisional Conflict Scale
Time Frame: Baseline
Measures the construct of decisional conflict, using a 5-point Likert scale with 12 question items. All question items have a positive valence, with higher scores indicating lower decision conflict. Scores range from 0-100.
Baseline
Decisional Conflict Scale
Time Frame: 1 Week Follow-up
Measures the construct of decisional conflict (at this timepoint, 1 week after baseline), using a 5-point Likert scale with 12 question items. All question items have a positive valence, with higher scores indicating lower decision conflict. Scores range from 0-100.
1 Week Follow-up
collaboRATE-Shared Decision Making
Time Frame: 1 Week Follow-up
Measures a participant's perceived degree of shared decision-making about treatment (at this time point: 1 week after baseline). All question items have a positive valence (higher scores indicating greater shared decision-making, a more positive outcome), with scores ranging from 0-100.
1 Week Follow-up
collaboRATE-Shared Decision Making
Time Frame: 1 Month Follow-up
Measures a participant's perceived degree of shared decision-making about treatment (at this time point: 1 month after baseline). All question items have a positive valence (higher scores indicating greater shared decision-making, a more positive outcome), with scores ranging from 0-100.
1 Month Follow-up
Satisfaction With Decision Making Process
Time Frame: 1 Month Follow-up
Measures a participant's satisfaction with their decision of treatment (at this time point: 1 month after baseline). All question items have a positive valence (higher scores indicating greater satisfaction with the decision making process, a more positive outcome), with scores ranging from 0-100.
1 Month Follow-up
Ottawa Decision Regret Scale
Time Frame: 1 Month Follow-up
The 'Decision Regret Scale' measures "distress or remorse after a (health care) decision." In a short introductory statement, respondents should be asked to reflect on a specific past decision, and then asked to indicate the extent to which they agree or disagree with the statements in the regret scale by indicating a number from 1 (Strongly Agree) to 5 (Strongly Disagree) that best indicates their level of agreement. Regret is measured at a point in time when the respondent can reflect on the effects of the decision. Items 2 and 4 should be reverse coded so that, for each item, a higher number will indicate more regret. To help others interpret the score more readily with other scales ranging from 0 to 100, these scores can then be converted to a 0-100 scale by subtracting 1 from each item then multiply by 25. To obtain a final score, the items are summed and averaged. A score of 0 means no regret; a score of 100 means high regret.
1 Month Follow-up
Satisfaction With Life Scale
Time Frame: Baseline
Measures participants' perceived Satisfaction with Life. Out of 0-30 scale. Higher scores indicate higher satisfaction with life.

Time Frame: 1 Month Follow-up

1 Month Follow-up
Preparedness for Decision-Making Scale
Time Frame: 1 Week Follow-up
The Preparedness for Decision-Making Scale assesses a patient's perception of how useful a decision aid or other decision support intervention is in preparing the respondent to communicate with their practitioner at a consultation visit and making a health decision (treatment/diagnostic/screening, etc.). Items can be summed and scored (sum the 10 items and divide by 10). B) Scores are converted to a 0-100 scale by: subtracting 1 from the summed score in part a) and multiplying by 25. Higher scores indicate higher perceived level of preparation for decision-making.
1 Week Follow-up

Time Frame: 1 Day Follow-up

1 Day Follow-up
Shared Decision-Making (SDM-9)
Time Frame: 1-Week Follow-Up
A brief patient-report instrument for measuring Shared Decision Making (SDM) in clinical encounters. All question items have a positive valence. Summing up all items leads to a raw total score between 0 and 45. Multiplication of the raw score by 20/9 provides a score forced (transformed) to range from 0 to 100, where 0 indicates the lowest possible level of SDM and 100 indicates the highest extent of SDM. As it is more intuitively interpretable, the authors of the scale encourage the use of the transformed score, which we used.
