Sickle cell disease (SCD) is an inherited disorder with chronic multi-system manifestations
affecting 100,000 individuals in the US, largely of minority origin and associated with
substantial morbidity, premature mortality, individual suffering, healthcare costs and loss
of productivity. Disease modifying treatments such as hydroxyurea, chronic blood transfusion
and curative bone marrow transplantation are offered to patients based on physician
preference and current practice informed by clinical trials. Decision aids are tools that
could help translate evidence from these sources into practice by helping clinicians involve
patients in making deliberate choices based on accessible information about the options
available and their outcomes and to help them make decisions based on their values and
preferences.
The overarching goal of this project is to implement a web based decision aid individualized
to patient characteristics to help patients with SCD achieve more accurate perception of
risks and benefits of treatment options and make decisions in congruence with their values
and preferences. Investigators will use a randomized controlled trial of the effectiveness of
a web-based decision aid to give patients accurate information about risks and benefits of
therapies that enable patients to make decisions based on their individual values and
preferences.

Type | Measure | Description | Time frame | Safety issue |
---|---|---|---|---|
Primary | Acceptability of Decision Aid Education Assessed by the Acceptability Survey | Subjects will take an acceptability of education questionnaire which is a 8-item survey to assess the comprehension of education received for the decision aid tool. Each item will be scored on a scale from 1-4 where 1=poor, 2=fair, 3=good, and 4=excellent. Scores will be rated individually 1-4 according to each item. There is no overall total score. | Post Visit 1 (Up to 2 Weeks) | |
Secondary | Mean Decisional Self-Efficacy Scale Score | The Decision Self-Efficacy Scale measures self-confidence or belief in one's ability to make decisions, including participate in shared decision making. Items are scored on a scale of 0-4 where 0 is not at all confident and 4 represents very confident.Total scores range from 0 (not at all confident) to 100 (very confident). A score of 0 means 'extremely low self- efficacy' and a score of 100 means 'extremely high self-efficacy. | Month 3, Month 6 | |
Secondary | Mean Difference in Decisional Conflict Scale Scores | Decisional Conflict scale responses are scored for the total score, uncertainty sub-score, informed sub-score, values clarity sub-score, support sub-score and effective decision sub-score. The total score ranges from 0 (no decisional conflict) to 100 (extremely high decisional conflict). The uncertainty sub-score ranges from 0 (feels extremely certain about best choice) to 100 (feels extremely uncertain about best choice). The informed sub-score ranges from 0 (feels extremely informed) to 100 (feels extremely uninformed). The values clarity sub-score ranges from 0 (feels extremely clear about personal values for benefits & risks) to 100 (feels extremely unclear about personal values). The support sub-score ranges from 0 (feels extremely supported in decision making) to 100 (feels extremely unsupported in decision making). The effective decision sub-score ranges from 0 (good decision) to 100 (bad decision). | Baseline, Month 3 | |
Secondary | Mean Difference in Decisional Conflict Scale Scores | Decisional Conflict scale responses are scored for the total score, uncertainty sub-score, informed sub-score, values clarity sub-score, support sub-score and effective decision sub-score. The total score ranges from 0 (no decisional conflict) to 100 (extremely high decisional conflict). The uncertainty sub-score ranges from 0 (feels extremely certain about best choice) to 100 (feels extremely uncertain about best choice). The informed sub-score ranges from 0 (feels extremely informed) to 100 (feels extremely uninformed). The values clarity sub-score ranges from 0 (feels extremely clear about personal values for benefits & risks) to 100 (feels extremely unclear about personal values). The support sub-score ranges from 0 (feels extremely supported in decision making) to 100 (feels extremely unsupported in decision making). The effective decision sub-score ranges from 0 (good decision) to 100 (bad decision). | Baseline, Month 6 | |
Secondary | Mean Values Survey Score | The values survey consists of 14 multiple choice questions to measure what is important to a patient when making decisions. The patient decision aid will be tested in the twelve domains of the international patient decision aid standards collaboration criteria checklist. Respondents will be asked to identify perceived importance of individual items (such as procedure related complications, decreasing complication risks, experiencing less pain) and to rate this importance on a 10 point likert scale (0-10) where 1 indicates "not important to me at all" and 10 indicates "extremely important to me". Scores are then converted it to an 11 point scale and averaged. | Post Visit 1 (Up to 2 Weeks) | |
Secondary | Mean Change in Preparation for Decision Making Scale Score | Preparation 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 focused on making a health decision. The preparation for decision-making scale is scored on a 0-100 scale. Higher scores indicate a higher perceived level of preparation for decision making. The total score on the decision making scale is a continuous outcome. | Month 3, Month 6 | |
Secondary | Mean Knowledge Survey Scores | Knowledge Survey is a 25 multiple choice questionnaire which assesses how much knowledge is being retained after information about risks is received. The knowledge survey is scored as percent correct answers at each time point. This is a set of questions to test knowledge and understanding about sickle cell disease and treatments. As such the answers are dichotomous i.e true or false. The total score of percent correct answers is scored in the range of 0-100%. | Baseline, Month 3, Month 6 | |
Secondary | Mean Decisional Regret Scale Score | Decision Regret Scale measures distress or remorse after a health care decision. The subject rates regret using a 5 point Likert scale in answering the following questions; 1. It was the right decision 2. I regret the decision 3. I would go for the same decision if I were to do it again 4. The decision caused me a lot of harm 5. It was a wise decision. Total scores range from 0 to 100. A score of 0 means no regret; a score of 100 means high regret. | Visit 3 |
