Diagnostic consistency between admission and discharge of pediatric cases in a tertiary teaching hospital in China

Abstract

Abstract Background Patient-centered, high-quality health care relies on accurate and timely diagnosis. Diagnosis is a complex, error-prone process. Prevention of errors involves understanding the cause of errors. This study investigated diagnostic discordance between admission and discharge in pediatric cases. Methods We retrospectively reviewed the electronic medical records of 5381 pediatric inpatients during 2017–2018 in a tertiary teaching hospital. We analyzed diagnostic consistency by comparing the first 4 digits of admission and discharge ICD-10 codes of the cases and classified them as concordant for “complete and partial match” or discordant for “no match”. Results Diagnostic discordance was observed in 49.2% with the highest prevalence in infections of the nervous and respiratory systems (Ps < 0.001). Multiple (multivariable) logistic regression analysis predicted a lower risk of diagnostic discordance with older children (aOR, 95%CI: 0.94, 0.93–0.96) and a higher risk with infectious diseases (aOR, 95%CI: 1.49, 1.33–1.66) and admission by resident and attending pediatricians (aOR, 95%CI: 1.41, 1.30–1.54). Discordant cases had a higher rate of antibiotic prescription (OR, 95%CI: 2.09, 1.87–2.33), a longer duration of antibiotic use (P = 0.02), a longer length of hospital stay (P < 0.001), and higher medical expenses (P < 0.001). Conclusions This study denotes a considerably high rate of discordance between admission and discharge diagnoses with an associated higher and longer prescription of antibiotics, a longer length of stay, and higher medical expenses among Chinese pediatric inpatient cases. Infectious diseases were identified as high-risk clinical conditions for discordance. Considering potential diagnostic and coding errors, departmental investigation of preventable diagnostic discordance is suggested for quality health care and preventing potential medicolegal consequences.
