To gather specific details about the information, communication, and treatment as regards users of hospital emergency services using a telephone survey, in order to implement improvement measures, if necessary. A prospective study was conducted in two emergency departments in Salamanca. A total of 400 patients were included in the study (mean age 56.4±20.5years, 58.4% women). A telephone survey was performed with 19 items, of which 12 required responses on a Likert-type scale, with scores of 1 (very bad) to 5 (very good). The remainder of the questions allowed to answer "yes" or "no". The treatment received by the professionals in general was evaluated positively by 86% of the patients; with 92% reporting they were respectful, 87% were treated by doctors and 71% received treatment from nurses. More than one-quarter (27.5%) did not recall receiving information from blue point staff (personnel specially trained to provide information. Statistical significance (P=.045) was found in relation to the kindness and respect shown by nurses. Most patients that were admitted to the observation area of the emergency department were not informed about the visiting hours (P=.003). Perception of care received by patients is good, while in relation to information and communication it is evidently improvable, and could be assessed using the survey that is proposed in order to detect and use the weaknesses in these aspects of health care as implementation initiatives.
