Introduction: in primary health care, the performance of general practitioners is important in tracking and monitoring the early stages of chronic kidney disease, due to the high prevalence, lack of specialists, impact on morbidity and quality of life and the high cost to health systems. The use of mobile applications has become important in contemporary medicine because it facilitates access to information, which optimizes the provision of health care.
Objectives: to develop and validate a mobile application on laboratory tests in chronic kidney disease, for general practitioners.
Methods: study in the technological production modality, with software development based on a literature review, with validation by specialists (nephrologists) and by general practitioners. Validation took place through answers to questionnaires, which evaluated content, understanding, language and graphic presentation of the mobile application. Cronbach's alpha coefficient was used to analyze the internal consistency of the questionnaires, and the Content Validity Index was used to assess physicians' agreement on aspects of the app. The value adopted for the mobile application was greater than 80%.
Results: the responses of nephrologists (n=9) and general practitioners (n=13) were, respectively, median age 40 (35-71) years and 45 (30-50) years, 5 (55%) and 7 (54%) were female, Cronbach's alpha coefficient of 0.8025 and 0.9145, Global Content Validity Index of 95.56% and 92.13%.
Conclusion: the reliability of the responses to the questionnaires was good and there was excellent agreement between the judges on aspects of the mobile application.
