Análisis global de la legibilidad de los documentos de consentimiento informado utilizados en los hospitales públicos de España

Resum

Purpose To analyse the readability of informed consent forms (ICF) used in Public Hospitals throughout Spain, with the aim of checking their function of providing comprehensive information to people who are making any health decision no matter where they are in Spain. Material and methods A descriptive study was performed on a total of 11,339 ICF received from all over Spanish territory, of which 1617 ICF were collected from 4 web pages of Health Portal and the rest (9722) were received through email and/or telephone contact from March 2012 to February 2013. The readability level was studied using the Inflesz tool. A total of 372 ICF were selected and analysed using simple random sampling. The Inflesz scale and the Flesch-Szigriszt index were used to analyse the readability. Results The readability results showed that 62.4% of the ICF were rated as a “little difficult”, the 23.4% as “normal”, and the 13.4% were rated as “very difficult”. The highest readability means using the Flesch index were scored in Andalusia with a mean of 56.99 (95% CI; 55.42-58.57) and Valencia with a mean of 51.93 (95% CI; 48.4-55.52). The lowest readability means were in Galicia with a mean of 40.77 (95% CI; 9.83-71.71) and Melilla, mean=41.82 (95% CI; 35.5-48.14). Conclusions The readability level of Spanish informed consent forms must be improved because their scores using readability tools could not be classified in normal scales. Furthermore, there was very wide variability among Spanish ICF, which showed a lack of equity in information access among Spanish citizens
