The objective of this study was to identify the body language of the social worker in the quality of care provided to users of the Hospitals of Manta and Portoviejo. For this, a survey was applied to 260 users of Manta and 285 users of Portoviejo attended in these health houses, which allowed to measure the degree of satisfaction that the user perceives with respect to the quality of service provided by the social worker, considering the result made using the servqual instrument, which determined that there is a high level of satisfaction. Conclusion obtained when analyzing the results of applying the questionnaire, where each indicator was analyzed in a consolidated manner. However, in the observation made to social work professionals, the need to implement a care manual that provides quality and warmth to the user was evident.
