Clinical Trial Summary

Although a CT scan is required for some Emergency Department patients with signs and symptoms of a kidney stone, recent evidence has shown that routine scanning is unnecessary and may expose young patients to significant cumulative radiation, increasing their risk of future cancers. Shared Decision-Making may facilitate diagnostic imaging decisions that are more inline with patients' values and preferences. By comparing a shared approach to diagnostic decision-making to a traditional, physician-directed approach, this study lays the foundation for a future randomized trial that will reduce radiation exposure, improve engagement, and improve the quality and patient-centeredness of Emergency Department care.

7. Moderate or severe abdominal tenderness or rebound/guarding, consistently present (present for more than one exam, or present after patient treated with pain medication)

8. Second doctor's visit (ED, PCP, urgent care) for THIS episode of pain (previous similar visits ok if pain gone for >30d in between episodes) (if seen at PCP or urgent care in same day or 24 hour period, this is not an exclusion, but if seen at PCP/urgent care or ED 1-30 days prior to index visit, with same pain, excluded)

9. Known history of one kidney or other urological/renal abnormality (including neurogenic bladder, ESRD and paraplegia; or if solitary kidney discovered on US)

10. Known malignancy (any) within past year (or received treatment in the past 12 months)

11. Immunocompromised (chronic steroids, HIV, crohns, immunomodulators or severely ill chronically)

12. On anticoagulation

13. Crisis patient (behavioral health)/belligerent

14. Lacks capacity for medical decision-making

15. Unlikely to respond to follow-up calls (IVDA, homeless, no phone)

16. Clinician is concerned for alternative diagnosis requiring CT scan (appendicitis) (>5% likelihood by clinician gestalt)

17. Patient is not improving clinically and clinician is considering admission

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Feasibility	Is this study feasible? We will collect number of patients screened, number approached, number consented, number randomized and whether follow-up was completed (was patient contacted). An enrollment of at least three patients per month will indicate feasibility.	Up to 12 months
Primary	Fidelity	Does the DA do what we think it is doing? Fidelity will be examined after 50 patients are enrolled: conversations between patients and clinicians will be scored for whether shared decision-making occurred. If SDM is NOT occurring in the intervention group (>75% of interactions) or IS occurring in the usual care group (>50% of interactions), fidelity will not be considered met.	Up to 12 months
Primary	Patient Knowledge	We hypothesize that the intervention group will have increased knowledge regarding radiation exposure and diagnostic options. This will be tested with a 10 question Knowledge Test developed by stakeholders for this study and delivered at the end of the index visit. The scores for this test range from 0-10 with 10 indicating higher knowledge (more correct answers)	Measured at the end of the index visit. (Day 0)
Primary	CT scan rate	We hypothesize that SDM will lead to a change in CT scans performed at the index visits and in the first 60 days	Day 0 and Day 60 (Day 60 evaluation will include all days from 0-60)
Primary	Radiation exposure	We hypothesize that SDM will lead to a change in exposure to radiation. We will record radiation exposure for each CT done between day 0 and day 60, as indicated by DLP on CT reports.	Day 0 and Day 60 (Day 60 evaluation will include all days from 0-60)
Secondary	Patient Satisfaction	Measure of satisfaction (HCAHPS measure: Provider rating where 0 = worst provider possible and 10 = best provider possible)	Day 0, end of visit
Secondary	Patient engagement	Measure of engagement: CollaboRATE 3-question measure (where 10/10 for all three is the highest score possible, and 0/0 is the lowest possible, with highest indicating better patient engagement)	Day 0, end of visit
Secondary	Patient engagement	Measure of engagement: modified CPS (Scale from 1-5, where 1 indicates the doctor made the decision, 5 indicates the patient made the decision, and 2,3, and 4 indicate levels of shared decision-making)	Day 0, end of visit
Secondary	Patient engagement	Measure of engagement: direct SDM question (Measures patients' perception of "Did SDM occur" on a likert scale of 1-7 with 1 = no and 7 = yes, and higher scores = more SDM)	Day 0, end of visit
Secondary	Occurrence of SDM	"As involved" question: "Were you as involved in today's decisions as you would have liked to be?" With three response options: Yes, No, and "There were no decisions for me to be involved in" Greater proportion of patients choosing "yes" indicates more SDM.	Day 0, end of visit
Secondary	Occurrence of SDM	Whether SDM took place from a third party observer's perspectives: OPTION-5 Score (where scale goes from 0-5, and is re-scaled to 0-100, where higher score indicates more SDM)	Day 0, end of visit
Secondary	Overall Radiation Burden	Radiation burden from diagnostic imaging (numeric DLP from CT reports)	within 60 days from index ED visit
Secondary	Trust in physician	Trust in physician scale (0-25 with 25 indicating higher trust in the physician)	Day 0, end of visit
Secondary	ED revisits	Repeat visits to any Emergency Department	60 days
Secondary	Safety: missed diagnosis	High Risk Diagnoses with Complications, as previously described by Smith-Bindman.	60 days from index ED visit
Secondary	ED Length of Stay	Total minutes of ED stay	Day 0, end of visit
Secondary	Implementation Outcomes	Clinician's perceptions of the conversation/intervention. We will ask about whether the clinician found the decision aid helpful, whether they would recommend it to another clinician, and whether they would use it again (likert scale 1-7 for each, with higher number indicating more acceptance/helpfulness)	Day 0, end of visit
Secondary	Qualitative evaluation	We will ask open ended questions to providers about their interaction, to ask about what went well, what did not, how else could SDM be facilitated, how this intervention would work outside of a study, what other feedback they have. This will be collected via recorded interview and open ended questions.	Day 0, end of visit
