摘要BACKGROUND:Acute pain is a sudden experience secondary to injuries and varies in perception among individuals.In trauma patients,it can negatively affect respiratory function,immune response,and wound healing,making it a significant public health concern.This study is to determine the prevalence and factors associated with acute pain among emergency trauma patients.METHODS:A multicenter cross-sectional study was conducted.Data were collected via interviewer-administered questionnaires and patient chart review.The data were analyzed via the statistical package for social science version 25.Bivariable and multivariable logistic regression analyses were used.Variables with a P-value＜0.05 were considered statistically significant.RESULTS:A total of 397 patients were included in the study,for a response rate of 96.8％.The prevalence of pain during admission was 91.9％(95％confidence intervals[95％CIs]:88.8％-94.4％).Blunt trauma(adjusted odds ratio[aOR]=2.82;95％CI:1.23-6.45),analgesia before admission to the emergency department(aOR=2.71;95％CI:1.16-6.36),documentation of pain severity in the chart(aOR=2.71;95％CI:1.16-6.36),analgesia provided within two hours after admission(aOR=7.60;95％CI:2.79-20.68),use of non-pharmacological pain management methods(aOR=3.09;95％CI:1.35-7.08)and availability of analgesia(aOR=3.95;95％CI:1.36-11.43)were associated with acute pain experience.CONCLUSION:The prevalence of acute pain among emergency trauma patients was high in the study area.Analgesia should be administered prior to admission,and non-pharmacological pain management should be implemented.Moreover,training on pain assessment and management should be provided for healthcare providers in the emergency department.
