Description

Percentage of overnight discharges from the mental health and addiction service organisation’s inpatient unit(s) where a community service contact was recorded in the seven days immediately following that discharge.

This KPI calculates an overall follow up rate, which is the percentage of all acute inpatient discharges that were followed up, regardless of where that follow up occurred (DHB, NGO or both)

Indictor rationale

A responsive community support system for persons who have experienced an acute psychiatric episode requiring hospitalisation is essential to maintain clinical and functional stability and to minimise the need for hospital readmission.

Service users leaving hospital after a psychiatric admission with a formal discharge plan, involving linkages with community services and supports, are less likely to need early readmission. Research indicates that service users have increased vulnerability immediately following discharge, including higher risk for suicide.

Denominator

Count of acute inpatient discharges

Numerator

Count of acute inpatient discharges where a follow up community contact (for the same person) exists, where:

Community follow-up ActivityStartDate is between 1 and 7 days after acute InpatientDischargeDate

• ActivityStartDate >= dateadd(1, day, InpatientDischargeDate)
• ActivityStartDate < dateadd(8, day, InpatientDischargeDate)

Note: as of November 2020 terminology has changed from ReferralClosureDate to InpatientDischargeDate to eliminate confusion.

General terminology

An acute inpatient referral discharge is any referral record where:

1. ReferralEndDate is not null — ended referral
2. TeamType is Inpatient — into an inpatient team
3. ReferralEndCode is DR, DW or DT — ended in a way where we expect follow-up
4. ReferralTo is not PI, AE or NP — was not moving on to another hospital setting
5. Exists at least one activity where — there was at least one acute inpatient bednight
   1. ActivityTypeCode is T02 or T03 — acute inpatient bednight codes
   2. ActivityUnitCount > 0– for more than 0 days

An inpatient discharge date is calculated as the:

1. Maximum ActivityEndDate for a referral record where: — end of last activity
   1. ActivityType is T02, T03, T04 or T37– inpatient activity only

A community contact is any activity record where:

1. TeamType is not Inpatient — not inpatient follow up
2. ActivityUnitType is contact — not a bednight, seclusion or leave
3. ActivitySetting is not WR, OM or SM — includes service user participation
4. ActivityType is not T08, T35 or T32 — includes service user participation

PRIMHD

Description

Percentage of overnight discharges from the mental health and addiction service organisation’s acute inpatient unit(s) that result in readmission within 28 days of discharge to the same organisation.

Numerator

Total number of acute inpatient overnight discharges closed in the reporting period that are followed by a readmission within 28 days.

Denominator

Same denominator as acute inpatient post discharge community care – 7 day follow up

Count of acute inpatient discharges

Technical notes

Numerator

Same definition as number of in scope discharges except that same day event is eligible for readmission, in addition to multi day readmission events. A readmission for any of the in scope discharges in the denominator is an admission to the same organisation that occurs within 28 days of the discharge date of the original inpatient discharge date

PRIMHD

Description

Acute inpatient occupied bednights for in scope discharges closed during the reporting period

Measurement dimensions

• Average
• Median

Technical notes

The average is derived by summing the number of acute inpatient occupied bednights, divided by the number of in scope discharges

The median is the middle value when eligible in scope discharges are ranked in order of length of stay, for example half the discharges are above the median length of stay and half are below.

Description

Percentage of overnight discharges from the mental health and addiction service organisation’s inpatient unit(s) closed in the reporting period for which a community service contact was recorded in the seven days immediately preceding the day of admission

Measurement dimensions

Percentages for

• Same DHB Only: Where face to face community mental health contact was recorded by the same DHB as the admitting DHB in the seven days pre admission. This is the core indicator and represented in the dashboard.
• NGO Only: Where face to face community mental health contact was recorded by only an NGO service in the seven days pre admission.
• DHB and NGO: Where face to face community mental health contact was recorded by the same DHB as the admitting DHB and NGO service in the seven days pre admission.
• Different DHB: Where face to face community mental health contact was recorded by a DHB other than the admitting DHB in the seven days pre-admission.
• Not seen: Where NO face to face community mental health contact was recorded by neither admitting DHB nor an NGO service in the seven days prior to admission.

Numerator

Number of in scope discharges in the denominator for which a face to face community mental health contact was recorded in the seven days immediately preceding the day of admission.

Contact must occur in the seven days prior to admission but not on the day of admission.

Denominator

Total number of in scope acute inpatient discharges closed during the reference period where the referral source is not from psychiatric inpatient

PRIMHD and Stats NZ DHB population projections

Description

Number of distinct service users secluded during a reporting period, irrespective of when the seclusion event started or ended.

Measurement dimensions

• Number of people secluded
• Number of people secluded per 100k Population

Numerator

Total number of distinct people with seclusion events overlapping the reporting period.

Denominator

Per 100K Population: DHBs population projection for the reporting period (/100,000) – aged between 20 and 64.

Some DHBs provide regional residential mental health services. For these DHBs, the effective population they serve is larger than the population (DHB based) used to calculate the per 100,000 population rate used by the seclusion indicator. The impact of this is that the DHBs with regional services could be recording a higher seclusion rate by population than is in fact the case.

Technical notes

Numerator

Eligible activity type: T33 (seclusion)

Process of identifying seclusion episode from PRIMHD:

1. Indexed seclusion activities by referral ID, individual and service organisation in order of activity start time.
2. Roll up continuous or overlapping seclusion activities into one episode.
3. Where there is less than 60 minute break between two seclusion events, it is concatenated into one event, in line with MOH definition.
4. Assign age at episode start.
5. Assign seclusion events to the corresponding reporting period. Where a seclusion event crosses over multiple reporting periods, both the event and individual is counted in multiple times across the reporting periods where it spans while seclusion hours are apportioned across the multiple reporting periods.
6. Filter for adult population and adult service by applying the following criteria:
   1. Team type code not = 05 (forensic team) and
   2. Age at episode start is between 20 and 64.

Denominator

Population:

• Projections produced by Statistics New Zealand according to assumptions specified by the Ministry of Health.
• Filter applied for the relevant financial year and population aged between 20 and 64.

Person secluded:

Count of distinct individuals that had at least one seclusion event during the reporting period

5. Roll up continuous or overlapping referrals with the same service organisation into one collapsed referral (episode).
6. Order eligible activities within the collapsed and filtered referrals.
7. Determine the first face to face contact and the first whānau contact (if exists).
8. Assign age at referral start and filter for clients where age at referral start is 18 and above.
9. Determine the time from first face to face contact to the first whānau contact.
10.  Assign flags where the first face to face contact is inpatient, community crisis or community non-crisis.
