Characteristics of patients admitted to an adult PICU as compared to general adult inpatient units: a service evaluation
Background: There is a need to ensure that mental health services adapt to the increasing demand for inpatient beds, particularly within PICUs. This study aims to identify risk factors and assess demographics of patients which may increase the risk of admission or transfer to a PICU.Method: A retrospective analysis of 85 discharges from an adult mental health unit. We collected data on demographics, admission, ICD-10 diagnosis and readmission figures. We compared two cohorts: those who required admission to a PICU and those who did not.Results: 18 (21.2%) patients were admitted to the PICU. They were younger, more likely to be male, single and unemployed. PICU admissions were more likely to have a forensic history (p = 0.009), substance misuse history (p = 0.074), to require seclusion (p<0.0001), police involvement (p = 0.443), physical health input in the form of senior medical or surgical advice (p = 0.026) and assessment at an acute hospital (p = 0.015). Schizophrenia and schizoaffective disorders were less common than substance misuse disorders within the PICU cohort (p = 0.535). They were also more likely to be discharged to another PICU and to be re-admitted.Conclusion: This population demonstrated that F10–19 diagnoses were the most frequent within the PICU cohort which contradicts the previous literature. We identified risk factors for admission to a PICU, demonstrating the demand for inpatient services to adapt to the needs and demographics of patients and allowing early identification of high risk individuals.
