TOPLINE:

Researchers developed 12 algorithms to identify individuals with psychosis using England’s Mental Health Services Data Set (MHSDS), with success rates aligning with national prevalence estimates and most algorithms recognising the same core patient group.

METHODOLOGY:

• Researchers developed 12 unique algorithms using MHSDS, incorporating data elements such as mental health clusters, scores on the Health of the Nation Outcome Scales, reasons for referral, primary diagnosis, and early intervention flags, individually or in combination.
• Analysis included data from 2,378,247 patients in secondary care during 2018-2019 and from 2,220,812 patients during 2017-2018.
• Investigators validated the resulting numbers by comparing them with national estimates of psychosis prevalence.

TAKEAWAY:

• The algorithms identified 99,204-138,516 cases of psychosis for 2017-2018 and 107,545-1,46,832 cases...
