The association between dementia severity and hospitalisation profile in a newly assessed clinical cohort: the South London and Maudsley case register.

After excluding repeat admissions for the same cause, similar trends were observed at the three-digit ICD and chapter level, although an increasing trend of SAR with dementia severity reached or approached statistical significance for disorders of the urinary system and pneumonia with an increasing trend with dementia severity, and a decreasing trend, which reached statistical significance, for pain in throat and chest ( online supplementary tables 3–4 , figures 2 and 3 ).

Although the proportion of patients with at least one admission increased with dementia severity, this did not reach statistical significance (p 0.097).

No chapters showed significantly decreasing SARs with increasing dementia severity, although the negative trend for diseases of the digestive system (K) was close to significance.
