Effective, timely, accurate, complete, clear, and understood communication by the recipient will reduce errors and improve patient safety. One method of effective communication is SBAR communication (Situation, Background, Assessment, Recommendation). This study aims to provide an overview of the effective communication of nurse- physicians by telephone. The study was conducted with a descriptive observational study approach to nurses in the hospitalization room. Measurement of frequency of implementation of nurse and doctor communication via telephone was using the SBAR communication sheet and survey using a questionnaire. The results of this study found that component A (Assessment) is a component of SBAR communication with the lowest frequency (32%) and the highest is R (Recommendation) 100%. Problem experienced by nurses when communicating with physicians include nurses who anticipate when physicians are not happy or offended when called (22%), physicians do not consider nurses' views when making decisions about patients (16%) and nurses do not have enough time to say something to physicians ( 16%). This study shows that SBAR communication has not reached 100% and the making of SOP (Standard Operating Procedures) is one solution to improve SBAR communication. Bantul X Hospital already has an SOP related to SBAR communication but its implementation is not good enough
