Abstract
Positive patient experiences can lead to better adherence to cancer treatment and greater patient health outcomes. The primary aim of this descriptive study was to determine whether commonly used cancer PREMs have been developed according to health literacy best practices. The secondary and third aims were to examine the development of PREMs and to assess their comprehensiveness against principles of patient-centered care. To assess adherence to best practice literacy principles regarding readability and understandability of commonly used cancer PREMs, three validated readability calculators and a validated instrument were utilized. To better understand how PREMs were developed, data about survey items, patient involvement, and expert consultation were collected. Finally, the Picker framework was used to evaluate the comprehensiveness of PREMs against principles of patient-centered care. Thirty-five PREMs studies met inclusion criteria for the study. The mean reading grade level of cancer PREMs was 9.7 (SD = 0.75, range = 8.2-11.2) with best practice recommendation being a grade 6 reading grade level. Twenty-eight PREMs were rated on understandability, with a mean score of 74% (SD = 10.6, range = 46-93%, with optimal score of greater than 80%). The mean number of items across PREMs was 49 (SD = 31, range = 13-136). Recommendations for the number of items to include in a questionnaire is 25-30 items. Most PREMs (n = 33, 94.3%) asked ≥ 1 double-barreled question. All PREMs addressed ≥ 2 patient-centered care principles. Cancer PREMs included in this study did not meet evidence-informed thresholds for readability and understandability. As such, it is possible that there may be gaps in how we understand the care experiences of low health literacy populations. Future development of PREMs should engage patients with low health literacy to ensure their perspectives are accurately captured and that PREMs are designed to meet the needs of all patients.
