Implementing the Decision-Aid for Lupus (IDEAL Strategy)

Clinic personnel's perception of the acceptability of the SLE Patient decision-aid (PtDA), measured using a validated scale with four (4) items with responses ranging from 1 ("completely disagree") to 5 ("completely agree"). The four items will be averaged to create one composite mean scale score (range 1-5), where higher scores reflect perceptions of greater acceptability (i.e., better outcome).

Clinic personnel's perception of the implementation success of the SLE Patient decision-aid (PtDA), measured using a validated scale with three (3) items with responses ranging from 1 ("Disagree") to 5 ("Agree"). These three items will be averaged to create one composite mean scale score (range 1-5), where higher scores reflect perceptions of greater implementation success (i.e., better outcome).

Clinic personnel's perception of the permanence of the SLE Patient decision-aid (PtDA), measured using one validated item that is scored ranging from 1 ("Not at all permanent") to 5 ("Extremely permanent"). This item will be examined by itself, where higher scores indicate perceptions of greater permanence of the decision-aid in the clinic (i.e., better outcome).

Clinic personnel's perception of the appropriateness of the SLE Patient decision-aid (PtDA), measured using a validated scale with four (4) items with responses ranging from 1 ("completely disagree") to 5 ("completely agree"). The four items will be averaged to create one composite mean scale score (range 1-5), where higher scores reflect perceptions of greater appropriateness (i.e., better outcome).

Clinic personnel's perception of the feasibility of the SLE Patient decision-aid (PtDA), measured using a validated scale with four (4) items with responses ranging from 1 ("completely disagree") to 5 ("completely agree"). The four items will be averaged to create one composite mean scale score (range 1-5), where higher scores reflect perceptions of greater feasibility (i.e., better outcome).

Decisional conflict was measured using the low literacy version of the Decisional Conflict Scale (DCS), a well-validated self-administered instrument, after viewing the SLE Patient decision-aid (PtDA). The low literacy version has 10 items with 3 response categories: yes, unsure, and no. Four subscale scores consisting of uncertainty about choice, feeling informed, values clarity, and feeling supported in decision-making were also calculated. DCS (and subscale) scores range from 0 (best) to 100 (worst) and scores >= 25 are consistent with clinically significant residual decisional conflict

The Interpersonal Processes of Care short form (IPC-SF) is a patient-reported, 18-item validated patient-reported patient-physician communication and care processes measure, assessed after viewing the SLE Patient decision-aid (PtDA). Scores range from 18 to 90, with higher scores indicating better patient-physician communication ± care.

Patient satisfaction with the ease of the use of the SLE Patient Decision-aid (PtDA) measured using a validated single item scale scored on an ordinal scale from (strongly disagree =1) to (strongly agree = 5). This item will be examined by itself, where higher scores indicate greater patient satisfaction with the decision aid (i.e., better outcome). This is a single item scale, and there are no subscales. It was adapted from another study that assessed satisfaction with iPad or interactive voice response.

The SLE Patient Decision-aid (PtDA) review times was expressed in minutes as patient-reported; this was supplemented by study coordinator's record of patient DA review time in-clinic prior to addition of this question. This patient self-reported question was added at the onset of the COVID-19 pandemic, where shelter-in-place orders led to stopping of in-person outpatient visits and all vists were converted to virtual visits using the phone or the video (Telemedicine).

Patient perception of the effect of the decision-aid on preparing the patient for decision making measured using the Patient Preparation for Decision Making (PDM) , a validated scale consisting of 10 questions scored on an ordinal scale from (not at all =1) to (a great deal = 5. Score ranged 0-100, 100 representing the highest preparation for decision-making. This was assessed after viewing the SLE Patient decision-aid (PtDA).

The patient acceptability survey is for the assessment of patient acceptability of the SLE Patient Decision-Aid (PtDA). Each question was rated from Poor (1) to Excellent (4). Total score ranged 1-4. DA acceptability refers to rating regarding the comprehensibility of component of the decision-aid, its length, pace, amount of the information, and the balance in presentation of the information about the options available and the overall suitability for decision making.

The feasibility of the study survey completion and the administration of the lupus decision aid in the busy clinic were assessed with a self-administered patient questionnaire consisting of 4 questions, 2 questions for each, the survey and for the process of viewing ± administering the lupus DA in the busy clinic. Responses ranged from strongly disagree (=1) to strongly agree (=5). Higher scores indicate higher feasibility of the survey and of the SLE Patient Decision-Aid (PtDA) administration respectively.

Patient perception of the SLE Patient Decision-Aid (PtDA) usefulness was aimed at assessing whether people would consider the the SLE PtDA to be useful at present and when they would think back to the time, they had made decisions about lupus treatments in the past (question 1), and whether the information contained in the lupus DA were adequate (question 2). It measured patient response of Yes vs. no to two simple questions. The tool is not yet a validated assessment but was based on our debriefing of lupus patients in the previous randomized study of lupus decision-aid.
