The prediction of relapse in presentation is central to psychiatric prognosis.

The Probability of Relapse Scale (PRORES) (Table 1) is used by the authors to predict the likelihood of relapse by psychiatric inpatients.

To tailor better care plans by knowing the likelihood of relapse and readmission to hospital.

Eighteen inpatients were diagnosed with the ICD-10 codes. Results were reported on a 5-point probability scale from 0 (less severe) to 10 (most severe). The 5 items are: degree of severity of illness, degree of patient's insight, frequency of readmission into hospital, probability of discontinuation of therapy and probability of relapse in the 4–6 weeks after discharge.

With the cut-off score at 25 (score 5 × 5 items), indicating a moderate level of relapse, we ascertained that 100% of patients with a personality disorder (usually borderline) and substance misuse relapse are readmitted shortly after discharge, compared with 85.71% of those with psychoses and 66% of those with mood disorders.

The PRORES can help support those patients who are at elevated risks of relapsing due to any of the major causes: discontinuation of treatment, chronicity and poor insight into their own condition (Table 1).
