This study looked at all patients admitted to a district hospital in England during one week. The prevalence of psychiatric comorbidity was 11.8% in 2,444 inpatients. These patients had higher inpatient mortality (8.7 vs 3.3%; p < 0.001), 30-day readmission rates (24.7 vs 9.7%; p < 0.001), length of stay (mean 16.7 vs 5 days; p < 0.001), admission numbers (mean 1.3 vs 0.6; p < 0.001) and emergency department presentations in the year prior to their index admission (mean 2.3 vs 1.1; p < 0.001). A total of 86.2% were admitted via emergency medicine, with peaks on Saturdays and Tuesdays, in the afternoon and around midnight.
