Objective To explore the perceptions of health professionals in an integrated network of public provision of health services regarding the implementation of the Law on Rights and Duties of People in Chile. Method Qualitative descriptive study. A stratified qualitative sample of 53 professionals from five low complexity centres and one from a high complexity centre, all part of the integrated network of health services in Valdivia, Los Rios Region, Chile, were selected according to the criteria of an overall saturation of the explored dimensions. The information was gathered through a semi‐structured, in‐depth interview carried out after signing the informed consent. Data were analysed using an inductive approach of content analysis. Results Three categories emerged from the interviews: conceptualization and knowledge, factors influencing the implementation and recommendations for strengthening the implementation, and seven subcategories. It was highlighted that health professionals in the health‐care network perceived difficulties in implementing the Law on rights and duties of patients. Among them were the lack of knowledge about the Law, poor exposure and a lack of resources for its implementation. They suggested adapting the infrastructure of the institution and offering training as recommendations to improve the implementation of the Law. Conclusions There are hindering factors for the implementation of the Law related to organizational and professional gaps in the institutions providing health care.
