Use Andersen's behavior model to explain non-urgent visits in emergency department: A single center study in southwest China.

Background: Non-urgent ED visit was an important contributor of emergency overcrowding. Previous studies showed that patients make non-urgent ED visits for many reasons and their ED use patterns may be influenced by many factors. However, seldom studies were theory-based research aimed to offer a systemic insight regarding this question.
Methods: This was a cross-sectional study conducted in the ED of a tertiary hospital in China guided by Andersen's behavior model of health service use. Patients triaged as non-urgent were surveyed using a self-administrated questionnaire to investigate the reasons for ED presentation and associated factors influenced their ED use patterns.
Results: Perceived severity of illness and urgent treatment need (374, 68.6%), accessible problems to alternative services (144, 26.4%) and referral by medical staffs (134, 24.6%) were most commonly reported reasons for ED presentation. Alternative service attempt before ED presentation was determined by two predisposing factors: education level (OR = 0.638, P < 0.05) and use of nearest medical institution (OR = 1.588, P < 0.05). Prior non-urgent ED use was explained by both predisposing and need factors. They were: nationality (OR = 3.057, P < 0.01), type of health problems (OR = 1.641, P < 0.01) and self-rated health status (OR = 0.769, P < 0.01).
Conclusion: Patients' perceived need of emergency care played an extremely important role in driving ED use although several factors were identified. Future studies aim to decrease non-urgent ED use in China may firstly gain success from patient education programs.
