Shared Decision Making in Health Care Visits for CKD: Patients' Decisional Role Preferences and Experiences.

Rationale & Objective: Research on shared decision making (SDM) in chronic kidney disease (CKD) has focused almost exclusively on the modality of kidney replacement treatment. We explored what other CKD decisions are recognized by patients, what their preferences and experiences are regarding these decisions, and how decisions are made during their interactions with medical care professionals.

Study Design: Cross-sectional study.

Setting & Participants: Patients with CKD receiving (outpatient) care in 1 of 2 Dutch hospitals.

Exposure: Patients' preferred decisional roles for treatment decisions were measured using the Control Preferences Scale survey administered after a health care visit with medical professionals.

Outcome: Number of decisions for which patients experienced a decisional role that did or did not match their preferred role. Observed levels of SDM and motivational interviewing in audio recordings of health care visits, measured using the 4-step SDM instrument (4SDM) and Motivational Interviewing Treatment Integrity coding tools.

Analytical Approach: The results were characterized using descriptive statistics, including differences in scores between the patients' experienced and preferred decisional roles.

Results: According to the survey (n=122) patients with CKD frequently reported decisions regarding planning (112 of 122), medication changes (82 of 122), or lifestyle changes (59 of 122). Of the 357 reported decisions in total, patients preferred that clinicians mostly (125 of 357) or fully (101 of 357) make the decisions. For 116 decisions, they preferred a shared decisional role. For 151 of 357 decisions, the patients' preferences did not match their experiences. Decisions were experienced as "less shared/patient-directed" (76 of 357) or "more shared/patient-directed" (75 of 357) than preferred. Observed SDM in 118 coded decisions was low (median4; range, 0 - 22). Motivational interviewing techniques were rarely used.

Limitations: Potential recall and selection bias, and limited generalizability.

Conclusions: We identified multiple discrepancies between preferred, experienced, and observed SDM in health care visits for CKD. Although patients varied in their preferred decisional role, a considerable number of patients expressed a preference for shared decision making for many decisions. However, SDM behavior during the health care visits was observed infrequently.

Plain-language Summary: Shared decision making (SDM) may be a valuable approach for common chronic kidney disease (CKD) decisions, but our knowledge is limited. We collected patient surveys after health care visits for CKD. Patients most frequently experienced decisions regarding planning, medication, and lifestyle. Three decisional roles were preferred by comparable numbers of patients: let the clinician alone decide, let the clinician decide for the most part, or "equally share" the decision. Patients' experiences of who made the decision did not always match their preferences. In audio recordings of the health care visits, we observed low levels of SDM behavior. These findings suggest that the preference for "sharing decisions" is often unmet for a large number of patients.
