Notes:
DAYS LIABLE FOR DETENTION is an optional data element in the Mental Health Minimum Data Set collection record and should only be present if one or more Legal Status within the Adult Mental Health Care Spell have occurred during the REPORTING PERIOD.

It is the total number of days detained or liable to be detained within the Adult Mental Health Care Spell within the REPORTING PERIOD. Each period of such days is recorded by a Legal Status and there may be more than one recorded during the course of an Adult Mental Health Care Spell.

There is a PERSON PROPERTY EFFECTIVE DATE and PERSON PROPERTY EFFECTIVE END DATE for each Legal Status and the calculation is based upon those detained or liable to be detained days which have occurred during the REPORTING PERIOD adjusted for where periods of Legal Status overlap the REPORTING PERIOD START DATE and/or REPORTING PERIOD END DATE (this includes where the period of DAYS LIABLE FOR DETENTION has not yet ended). Where such overlaps occur the REPORTING PERIOD START DATE and/or REPORTING PERIOD END DATE should be used instead of that of the Legal Status.

DAYS LIABLE FOR DETENTION is the sum of the calculated periods of Legal Status days and should be recorded left justified with leading zeros.

Legal Status is a CATEGORY VALUED PERSON OBSERVATION where CATEGORY VALUED PERSON OBSERVATION TYPE is National Code 07 'Legal Status Classification'.

Adult Mental Health Care Spell is an ACTIVITY GROUP where ACTIVITY GROUP TYPE is National Code 23 'Adult Mental Health Care Spell'.
