Example:

All patients are in the same facility, during the month, are all non-Medicare, and are all strata three. These are the only non-Medicare patients in the facility during the month and all events receive a Measure Category Assignment = “E” in the appropriate measure.

Initial Patient Population – Non-Medicare is the non-Medicare Census Data for the unit/facility for the month, transmitted as Days.  This is not determined by the number of non-Medicare patients that are processed through the initial patient population algorithm.  Instead, it is calculated as:

= (Psychiatric Inpatient Days - Leave Days), transmitted as Days

Each patient has a value for Psychiatric Inpatient Days and Leave Days (refer to the HBIPS Spec manual for more information).  So, for this example:  Initial Patient Population – Non-Medicare = (10-0) + (15-0) + (30-1) + (5-0) + (10-0) + (20-1) = 88. 

This same value will be reported for both HBIPS-2a and HBIPS-3a Initial Patient Population.

Number of Denominator Cases is the same non-Medicare Census Data for the unit/facility for the month used to calculate the Initial Patient Population – Non-Medicare, except Number of Denominator Cases is transmitted as Hours:

= (Psychiatric Inpatient Days - Leave Days), transmitted as Hours

Each patient has a value for Psychiatric Inpatient Days and Leave Days (refer to the HBIPS Spec manual for more information).  So for this example: 

Number of Denominator Cases = (10-0) + (15-0) + (30-1) + (5-0) + (10-0) +(20-1)= 88 days * 24 hrs = 2,112 hours

The same value will be reported for both HBIPS-2a and HBIPS-3a Denominator Population

Number of Numerator Cases is calculated from patient data successfully processed through the measure algorithm.  It is the sum of the monthly minutes (converted to hours) related to the event for those patients’ cases with a Measure Category Assignment = ‘E’ for the measure.

Number of Numerator Cases for the restraint measure = 30 minutes, converted to hours = .5 hours

Number of Numerator Cases for the seclusion measure = 90 minutes, converted to hours = 1.5 hours

Number of Cases for Ratio is calculated from patient data successfully processed through the measure algorithm.  It is the count of the number of patients represented in the data element Number of Numerator Cases.  This is not the count of the number of events during the month, it is the number of patients that had an event during the month.  If no event occurred, then a zero (0) is transmitted.

 Number of Cases for Ratio for the restraint measure = 3 patients

Number of Cases for Ratio for the seclusion measure = 3 patients
