Confi abilidade interobservador da Classifi cação Internacional de Cuidados Primários Interobserver reliability of the International Classifi cation of Primary Care

ABSTRACT OBJECTIVE: The International Classi fi cation of Primary Care was developed as an attempt to overcome the limitations of the International Statistical Classifi cation of Diseases and Related Health Problems, 10th revision, when used for primary health care. The aim of the study was to evaluate the interobserver reliability of the International Classifi cation for Primary Care when coding reasons for health-related interruption of daily activities. METHODS: Data analyzed pertained to 801 subjects from Phase 2 of the Pro-Saude Study, involving the employees of a Rio de Janeiro university who reported having been prevented from carrying out any of their usual activities (work, study, or leisure) for health-related reasons in the two weeks prior to data collection. Health problems reported in response to an open question were separately coded by two classifi ers. Interobserver reliability with respect to number of health problems was calculated by weighted kappa; for the remaining analyses (chapters and full codes), crude kappa coef fi cients were used.
