OBJECTIVES:The aim of this study was to determine the readmission rates of Acute and Transient Psychotic Disorders (ATPD) who were admitted for the first time in the National Center of Mental Health from January to December 2012.
METHODOLOGY: This study used the retrospective cohort method. Patients included in the study were admitted for the first time with a diagnosis of Acute and Transient Psychotic Disorders (ATPD) during the period of January to December 2012. The source of data involved the chart review during the first admission and the subsequent admission. Patients who were readmitted beyond one year from time of admission were excluded.
RESULTS:Results showed that 25 out of 204 (12.26%) patients diagnosed with an ATPD were readmitted within one year. The most common diagnosis of ATPD upon admission were: Acute Schizophrenia-Like Psychotic Disorder (n=95), Other Schizophrenia (n=90) and Acute Polymorphic Psychotic Disorder (n=19). ATPD's with the highest 1 year readmission rates were Acute Polymorphic Psychotic Disorder (3/19),Other Schizophrenia (13/90) and Acute Schizophrenia-Like Psychotic Disorder(9/95).Those that were readmitted had a different discharge diagnosis in their second admission.The three most common diagnosis upon readmission were Undifferentiated Schizophrenia (36%), Bipolar Affective Disorder, current episode manic, with psychotic symptoms (24%) and Other Schizophrenia (12%). Acute Schizophrenia-Like Psychotic Disorder were mostly readmitted as Bipolar Affective Disorder in 44% of patients; Acute Polymorphic Psychotic Disorder (APPD) were readmitted as another ATPD (66.6%); and Other Schizophrenia was diagnosed as Undifferentiated Schizophrenia (54%).
CONCLUSION:Only a small percentage of patients with ATPD were readmitted one year from admission and those who were readmitted revealed that they may have actually been suffering from or developed another more chronic psychotic disorder.
