Predominant diagnoses, gender, and admission duration in an adult psychiatric inpatient hospital in United Kingdom

Introduction: The study objective was to epidemiologically analyse patients presenting at an adult and mixed-gender psychiatric inpatient unit in Essex, Kingswood Centre, UK, to report the predominant diagnoses, gender, and admission duration. Method and material: Meta-analysis and descriptive statistics analysed the year 2016 discharge data on Excel® for 162 patients. ICD-10 codes classified their mental illnesses. Results: Meta-analysis evidenced statistically significant heterogeneity in numbers admissions (I2=95%; p≤0.001), length (I2=78%; p≤0.001), and gender (I2=76%; p≤0.001). The prevailing diagnosis was borderline personality disorder (BPD) (rate, 95% CI=0.46 [0.38-0.54]). The longest admission was for schizoaffective disorder (mean duration, 95% CI=53 [22.65-83.34], p=0.001). Gender presented a prevalence of male over female admissions for schizophrenia (OR, 95% CI=0.14 [0.05-0.35], p≤0.001) and BPD with prevalence of female over male admissions (OR, 95% CI=2.79 [1.35-5.76], p=0.05). Conclusion: Female patients with BPD were the most represented category in non-forensic psychiatric inpatient wards in the population studied. Male patients with schizophrenia represented the other gender highly represented. The longest admission was recorded for schizoaffective disorder due to the complexity to treat both mood and psychotic symptoms. It is likely that women with BPD will be the future recipients of psychiatric inpatient and outpatient healthcare services.
