Het vergroten van de betrokkenheid van patiënten bij de besluitvorming over borstkankerchirurgie
Het vergroten van de betrokkenheid van sociaaleconomisch achtergestelde patiënten bij besluitvorming over borstkankerchirurgie door middel van een interventie voor gedeelde besluitvorming
This trial studies how well a breast cancer surgery decision aid works in increasing patient engagement in decision making for patients with newly diagnosed stage 0-III breast cancer. The trial also examines barriers to patient engagement even with the use of a decision aid, and if barriers are more likely to be experienced by socioeconomically disadvantaged patients.

Gedetailleerde beschrijving
The primary and secondary objectives of the study:
PRIMARY OBJECTIVES:
I. Test the effectiveness of a breast cancer surgery decision aid in increasing patient engagement in decision making (measured by knowledge and power) in clinics serving a high proportion of socioeconomically disadvantaged patients.
II. Test the extent to which the effect of a decision aid on patient engagement is mediated through the mitigation of barriers and determine if persistent barriers are disproportionately experienced by socioeconomically disadvantaged patients.
SECONDARY OBJECTIVES:
I. Characterize how persistent barriers influence patient engagement in decision making in order to identify targets for adjunct interventions that could be implemented in clinics serving a high proportion of socioeconomically disadvantaged patients.
Trial Design:
OUTLINE: This is a multi-site cluster randomized trial using a stepped wedge design. Ten clinics will be recruited for participation. All clinics will begin in the usual care arm. Clinics will be randomized to the timing with which they cross-over to the decision aid intervention, with new clinics crossing over every 10 weeks.
ARM I: usual care
ARM II: decision aid intervention
The only difference between patients enrolled before institutional crossover and patients enrolled after institutional crossover is those who are enrolled after institutional crossover will have been offered the decision aid as accepted practice in the clinic.

Primaire uitkomstmaten

Maatregel Beschrijving |
Tijdsspanne |
|---|---|---|
|
Patient Power: Self-efficacy in Patient Physician Interactions
Tijdsspanne: 3 weeks
|
Power is defined as patients' self-perceived capacity to influence the decision-making encounter. This construct is measured using the Patient's Self-Efficacy in Patient-Physician Interactions (PEPPI)-5 point scale; the primary outcome measure is a total score ranging from 5-25, where higher scores indicate increased self-efficacy. The patient completes the PEPPI-5 questionnaire within 3 weeks post-surgical consultation. |
3 weeks
|
|
Patient Power: Active Patient Participation
Tijdsspanne: 1 day
|
Power is also separately measured by the validated Active Patient Participation Behaviors System to assess active patient participation during the surgeon consultation and is measured off the audio-recording of the consultation; a summary measure of patient's active involvement in the interaction is coded by the study team and represents a total count of patients' communicative behaviors (i.e., count of patient asking questions, count of patient assertive responses and count of patient expressions of concern) ranging from 0-114, where higher scores indicate increased active patient participation. The consultation for a patient will typically be study day 1 (day of registration). |

Patient Knowledge
Tijdsspanne: Up to 3 weeks
|
Patient knowledge is measured from 5 knowledge questions in the Decision Quality Instrument-Breast Surgery survey, with a percent correct recorded as the secondary outcome measure, ranging from 0-100%. The patient completes the Decision Quality Instrument-Breast Surgery survey within 3 weeks post-surgical consultation. |
Up to 3 weeks

Percentage of Concordant Between Surgery Received and Patient Treatment Preference
Tijdsspanne: Up to 3 weeks
|
This binary outcome indicates whether the surgery received (mastectomy or lumpectomy) was concordant with the patient's treatment preference. Patient's goals/concerns (keep the breast, remove the breast for peace of mind, avoid radiation), rated from 0 (not at all important) to 10 (extremely important), and treatment preference (lumpectomy only, lumpectomy and radiation, mastectomy, other surgery, or not sure) are measured with the Decision Quality Instrument (DQI)-Breast Surgery survey, completed within 3 weeks post-consultation. Concordance is derived using the method of Sepucha et al. (2012): (1) estimate a predicted probability (pp) of surgery preference from a multivariable logistic regression model with patient's goals/concerns and stage as independent variables; (2) classify patients as concordant if pp >= 0.5 and mastectomy was received, or pp < 0.5 and lumpectomy was received; and (3) calculate the percentage of concordant. |
