Background Patient-reported outcome measures (PROMs) are commonly used by healthcare providers as means of assessing health-related quality of life and function at any given time. The complexity of PROMs can differ and when combined with varying degrees of adult literacy, error can be introduced if patients fail to understand questions. With an average adult literacy level of 11-year-old students in the United Kingdom, it is unclear to what degree PROMs can be read and understood by most patients (readability); to our knowledge, this has not been evaluated. Questions/purposes We wished to determine the readability of commonly used PROMs in orthopaedic surgery, as assessed by a validated tool that measures the complexity of the language in these surveys. MethodsWe performed a MEDLINE search to identify the most-commonly reported PROMs in orthopaedic research. One hundred twenty-one PROMs were identified and reviewed by 19 attending orthopaedic surgeons at our institution. Fifty-nine were selected as the most commonly used in our department. Of these, 52 (78%) were disease specific and included: 12 (20%) knee, 10 (17%) shoulder, seven (12%) spine, six (10%) hip, five (8%) foot and ankle, four (7%) elbow, three (5%) pelvis, three (5%) hand and wrist, and two (3%) lower limb. The remaining seven (12%) PROMs were general health questionnaires. The Flesch Reading Ease Score is a validated readability tool measuring average sentence length and syllables per word. It is expressed on a scale from 0 to 100 with higher scores indicating easier reading. We extracted the text from each PROM and inserted it in the same online Flesch Reading Ease Score calculator to generate a score. Results The mean readability score was 55 (range, 0-93), corresponding to text best understood by 16-to 18-year-old

Introduction The aim of this study was to objectively ascertain the level of readability of standardised consent forms for orthopaedic procedures. Methods Standardised consent forms (both in summary and detailed formats) endorsed by the British Orthopaedic Association (BOA) were retrieved from orthoconsent.com and assessed for readability. This involved using an online tool to calculate the validated Flesch reading ease score (FRES). This was compared with the FRES for the National Health Service (NHS) Consent Form 1. Data were analysed and interpreted according to the FRES grading table. Results The FRES for Consent Form 1 was 55.6, relating to the literacy expected of an A level student. The mean FRES for the BOA summary consent forms (n=27) was 63.6 (95% confidence interval [CI]: 61.2-66.0) while for the detailed consent forms (n=32), it was 68.9 (95% CI: 67.7-70.0). All BOA detailed forms scored >60, correlating to the literacy expected of a 13-15-year-old. The detailed forms had a higher FRES than the summary forms (p<0.001). Conclusions This study demonstrates that the BOA endorsed standardised consent forms are much easier to read and understand than the NHS Consent Form 1, with the detailed BOA forms being the easiest to read. Despite this, owing to varying literacy levels, a significant proportion of patients may struggle to give informed consent based on the written information provided to them.
