How this service works
Bush 1996 23-item catatonia rating scale from caller-assigned integers. Items 1-16 and 22-23 are 0-3; mitgehen, gegenhalten, ambitendency, grasp_reflex, and perseveration are 0 or 3 only. Severity is the sum of items 1-23 (max 69). The 14-item screen is positive iff at least two of items 1-14 score above 0. magent does not perform the standardized examination. Not a diagnosis, not DSM catatonia criteria, not a medical device.
Output
Returns the summed BFCRS severity score across all 23 items (maximum 69), and a boolean or positive/negative result for the 14-item screening subscale (positive if at least two of items 1-14 score above zero).
Example use cases
EHR catatonia severity tracking
“A patient was rated today: excitement 0, immobility/stupor 3, mutism 3, staring 2, posturing/catalepsy 2, grimacing 1, echopraxia/echolalia 0, stereotypy 1, mannerisms 0, verbigeration 0, rigidity 2, negativism 2, waxy flexibility 2, withdrawal 2, impulsivity 0, automatic obedience 1, mitgehen 0, gegenhalten 0, ambitendency 0, grasp reflex 0, perseveration 0, combativeness 0, autonomic abnormality 1. What is the BFCRS total severity score and is the screening positive?”
Research dataset batch scoring
“I have item ratings for a study participant on the Bush-Francis scale: excitement 1, immobility/stupor 1, mutism 0, staring 1, posturing/catalepsy 0, grimacing 0, echopraxia/echolalia 1, stereotypy 0, mannerisms 1, verbigeration 0, rigidity 0, negativism 0, waxy flexibility 0, withdrawal 0, impulsivity 0, automatic obedience 0, mitgehen 0, gegenhalten 0, ambitendency 0, grasp reflex 0, perseveration 0, combativeness 0, autonomic abnormality 0. Compute the 23-item total and tell me if the 14-item screen is positive.”
Clinical decision support alert
“Run the Bush-Francis catatonia rating for a patient whose rater assigned: excitement 2, immobility/stupor 2, mutism 1, staring 2, posturing/catalepsy 2, grimacing 2, echopraxia/echolalia 1, stereotypy 1, mannerisms 1, verbigeration 1, rigidity 1, negativism 1, waxy flexibility 1, withdrawal 1, impulsivity 1, automatic obedience 1, mitgehen 3, gegenhalten 0, ambitendency 0, grasp reflex 0, perseveration 0, combativeness 1, autonomic abnormality 1 — I need the severity score and screen status to decide on next steps.”
Technical details
Endpoint
GEThttps://api.magentlab.com/api/calc/bush_francisWhen to prefer
Use this endpoint when you need automated, reproducible arithmetic for the Bush 1996 23-item Bush-Francis Catatonia Rating Scale — specifically when a human rater has already assigned integer scores to each item and you need the total severity sum and 14-item screen result computed without manual addition. It is not a substitute for clinical examination, DSM diagnosis, or a medical device.
Side effects
- Missing any of the 23 required query parameters causes a validation error
- Supplying a value other than 0/3 for binary-only items (mitgehen, gegenhalten, ambitendency, grasp_reflex, perseveration) returns an error
- Supplying out-of-range integers (e.g. 4 for a 0-3 item) causes a schema validation failure
- Network or payment (x402) issues may result in a 402 or 5xx response
