Development of a tailored survey to evaluate a patient-centered initiative.

OBJECTIVES

Patient-centered care initiatives have proliferated, but assessing their effectiveness requires measures tailored to their likely effects. In this article, we describe the development and pilot testing of patient surveys used to assess change in patients' cancer care experiences over time in response to a patient-centered care initiative.

STUDY DESIGN

Prospective case series.

METHODS

Domains of patient-centered care were informed by the goals of the initiative and a review of existing tools. Items were selected and modified from 6 domains of validated or semivalidated instruments. Items were piloted with patients with cancer in waiting room settings to further assess the relevance and clarity of items, whether important concepts were missing, and acceptability regarding place and timing of the surveys and to estimate baseline top box scores (percentage of patients scoring an item the highest quality level) to minimize likely ceiling effects. The instrument was then administered to a consecutive sample of Stanford Cancer Center patients. Baseline item responses, Cronbach's alpha, and response bias were estimated.

RESULTS

Items were modified based on patient feedback, top box scores, and reassessment of the domains. Over 6 months, 11,273 patients were surveyed, with a 49.7% response rate. Baseline top box scores ranged from 41.7% to 75.0% for any given item. Reliability and internal consistency were high for all domains (Cronbach's alpha ≥0.80) except for the access domain.

CONCLUSIONS

We developed reliable instruments to evaluate the essential elements of a patient-centered care initiative at an academic medical center, which minimized patient burden and maximized the response rate.
