Abstract: ObjectiveTo explore the state of misdiagnosis, missed diagnosis and excesseive diagnosis related to cerebral palsy(CP).Methods389 cases were retrospectively analyzed who were misdiagnosed, missed or escessively diagnosed related to CP as the first diagnosis in the inpatient and outpatient department from July 1999 to March 2010.ResultsAmong 389 cases, 156 cases were missed or misdiagnosed as nutritional disease, and 118 cases of other diseases were misdiagnosed as CP, while 115 cases who were normal children was excessively diagnosed as CP. The false diagnosis had relativity with children's age: doctors are more prone to make misdiagonsis when the children's age are smaller, while 293 cases were misdiagnosed before 12 months old (75.3%); 102 cases (65.4%) were misdiagnosed or missed as other diseases before September, 2004, while 87 cases (75.7%) were excessively diagnosed as CP after September, 2004. Frequency of misdiagnosis as CP reduced from 2004, and the proportion dropped from 55.9% to 44.1%.ConclusionIt is very important to master the diagnostic standard of CP. Both sides of the question are important, one side is to make early diagnosis and early treatment in order to achieve the best effect of rehabilitation, and the other side is to prevent misdiagnosis and excessive diagnosis which woud delay illness, or waste medical resources, increase the financial and psychological burden.
