Abstract: Objective: To investigate the status quo of health information seeking behavior and health behavior ability of PICC outpatients, and to explore and analyze their relationship, so as to provide support for the management of PICC outpatients.Methods: A total of 138 PICC patients in outpatients of a grade A hospital in Tianjin from February to December 2020 were selected as the study subjects by convenience sampling method. The general data questionnaire, health information search behavior scale and health behavior scale were used for cross-sectional investigation. Pearson correlation analysis was used to explore the relationship between health information search and health behavior ability. Results: The total score of health information searching behavior was 158.46±15.70, and the scores of each dimension from high to low were health information demand, information searching attitude, access to information barrier, information source. The total score of healthy behavior ability was 99.24±9.77, it was at a high level, including 87 cases (63.1%) good, 46 cases (33.3%) normal, and 5 cases(3.6%) poor, the each dimension were nutrition (24.91±3.46) , sports (25.17±3.35) , psychological well-being (24.15±3.14), health responsibility (25.01±2.72). Pearson results showed that health information searching attitude, information demand and information source were positively correlated with the total score of health behavior ability and the scores of each dimension (r= 0.263~0.462, P<0.05).There was a negative correlation between access to information and the total score of decision-making ability and the scores of each dimension(r=-0.168~-0.251, P<0.05). Conclusion: PICC outpatients’ health information searching behavior attitude is at a medium level, the information demand level is high, but the searching way is more limited, there is a certain degree of information acquisition obstacles; The more positive the patient’s attitude of information searching, the higher the healthy behavior ability. It is suggested that based on patients’ health information demand orientation and information searching behavior characteristics, medical staff should provide personalized guidance and various forms of health education for patients， lack of information, so as to improve patients’ health behavior ability and improve health outcomes.
