Objective

To investigate the current status and influencing factors of knowledgeattitudes-practices (K-A-P)among pediatricians regarding the clinical diagnosis and treatment of infant cow's milk protein allergy (CMPA).

Methods

A total of 546 pediatricians from medical institutions at various levels in Sichuan Province from November to December 2022 were selected as survey subjects by convenient sampling method.A self-designed questionnaire on K-A-P Regarding the Clinical Diagnosis andTreatment of Infant CMPA was administered to these pediatricians.Independent-samples t test or one-way ANOVA were used for univariate analysis of influencing factors of K-A-P scores of clinical diagnosis and treatment of infant CMPA,and multiple linear stepwise regression analysis was used for multivariate analysis.This study complied with the requirements of the HelsinkiDeclaration of the WorldMedical Association

Results

①A total of 554 questionnaires were collected,of which 546 were valid,with a valid questionnaire collection rate of 98.6%.②The scores of K-A-P dimensions of clinical diagnosis and treatment of infant CMPA were (13.3±3.2)points, (27.5±3.6)points,and (51.7±9.8)points,respectively.In the K dimension,there were 8 items with a wrong answer rate of>50%.The lowest score in the A dimension was for the reverse question "Avoiding milk and eggs during maternal pregnancy reduces the incidence of allergic diseases in offspring",with 31.9%(174/546)respondents choosing"strongly agree or agree".In the P dimension,34.2%(187/546)respondents"sometimes,occasionally,or never"followed CMPA-related guidelines for the home-based"gradual introduction of milk proteins"in children with mild to moderate non-immunoglobulin(Ig)E mediated CMPA.③Univariate analysis showed that the highest educational level,professional title,hospital level,and department were potential influencing factors for scores of K dimension of clinical diagnosis and treatment of infant CMPA (P <0.05);hospital level and department were potential influencing factors for scores of A dimension (P<0.05);professional title,working lifetime,hospital level,and department were potential influencing factors for scores of P dimension (P <0.05).④Multivariate analysis revealed that the regression equations for K-A-P scores of clinical diagnosis and treatment of infant CMPA were y K =13.087+1.612 dep1+2.208 dep2-4.113 dep3y A=27.697+0.895 dep1+1.770 dep2y P=51.970+2.623 dep1+5.904 dep2,and y Ky A,and y P represented the scores of respective dimensions,and dep1dep2dep3 represented child healthcare department,pediatric gastroenterology department,and otolaryngology department,respectively.Conclusions The current K-A-P levels of pediatricians in the management of infant CMPA are insufficient,which are manifested in misconceptions about knowledge,lack of confidence in attitudes and insufficiently standardized behaviors.The department where the pediatrician works is a common influencing factor on the scores of K-A-P dimensions of the clinical diagnosis and treatment of CMPA in infants.The communication and unification between different specialties is very n ecessary.Targeted training and communication for pediatricians in relevant departments will help improve the K-A-P level and standardize diagnosis and treatment behaviors of CMPA.
