Conditions
Brief summary
In this study, the investigators will develop and evaluate a novel intervention using standardized patients (SPs) -- or actors playing the roles of patients -- to enhance physicians' patient-centered counseling skills regarding two frequently overused, potentially inappropriate services in primary care: magnetic resonance imaging (MRI) for acute low back pain and bone densitometry in women at low-risk for osteoporosis. The investigators will further evaluate whether intervention effects on physician patient-centeredness generalize to counseling regarding other costly, unnecessary diagnostic tests.
Interventions
BEHAVIORALStandardized Patient Instructor Intervention
In each case, patients will harbor underlying concerns about a serious underlying condition (e.g., either disc herniation or osteoporosis) and will request inappropriate tests. Standardized patient instructors (SPIs) will portray new patients visiting the clinic for the first time, and electronic medical records will be identical to that of actual new patients. During the initial part of intervention visits, SPIs will assess the extent to which PCPs engage in patient-centered techniques specified in the final intervention model. SPIs will then break of their role and either teach or reinforce PCP use of the techniques, presenting techniques in a logical sequence while emphasizing flexibility in their use. SPIs will use scripts to deliver the interventions, providing opportunities for PCPs to ask questions, discuss concepts, and practice (by role playing) patient-centered techniques.
BEHAVIORALControl
In the latter half of visits with control PCPs, standardized patient instructors will share information with physicians regarding the acute low back pain self-care and bone health, but will not discuss patient-centered techniques or conduct training. The total duration of the control information sharing will be about one-third the SPI intervention to enhance patient-centeredness.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Number of inappropriate diagnostic tests ordered | 9 months | Investigators will assess via blinded, standardized chart review whether study physicians ordered inappropriate diagnostic tests for unannounced standardized patients who request testing during three follow-up visits occurring 3 to 9 months post-randomization. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Use of patient-centered counseling techniques | 9 months | Physician use of patient-centered counseling techniques as assessed via masked recordings of three standardized patient visits |
| Actual diagnostic test ordering among real patients | 9 months post-intervention | Among real patients seen by study physicians, we will assess diagnostic test ordering among actual adult patients during the post-intervention period. We will also assess comparable diagnostic test ordering during the pre-intervention period to enable adjustment for baseline test ordering. |
Other
| Measure | Time frame | Description |
|---|---|---|
| Standardized Patient Satisfaction | 9 months | Standardized patients will complete a measure of patient satisfaction based on the Consumer Assessment of Health Plans Survey (CAHPS) during each of three unannounced visits occuring during the follow-up period |
