The multiplier comes from the number of appointments possible in a 3.5 hour half-day and the average number of appointments to complete an intervention.

Multiplier = Appointments per half day of Core Partnership x 11.25 (if same amount of annual and study leave) divided by the Average number of appointments in Core Partnership

It’s however many appointments you have to offer in a 3 month period divided by the average number of appointments needed to complete treatment on average in core work.

Example 1: let’s say you work in a rural outreach service and can only offer 1.5 appointments per half day due to travel times. Then the multiplier = 1.5 x 11.5 /7.5 = 2.3

Example 2: perhaps your service has a large number of referrals of children with learning disability (or you are a learning disability CAMHS team). You are sure that the core average treatment duration is 10 due to the slower pace. Then the multiplier is 2 x 11.5/10= 2.3 again. If you do only home visits in core work (and so 1 appointment in a half day due to increased travel time) then 1 x 11.5/10= about 1

TIP: If you travel a lot, you may find it easier just to add up how much time you spend per week on travel and allocate this in job plans, rather than reducing the Core Partnership Multiplier - the effect is similar.

You may find your current appointment average is more than 7.5. But if you are not running CAPA this will include Specific Partnership work too, which will increase your average. You should also become more focused and find the service flows better with CAPA. This means running CAPA is likely to reduce your average appointment number, including for Specific Partnership work. So try 3 and if you seem really out of balance, do some investigating to work out why - use the Troubleshooting section to help you.

In New Zealand CAMHS their appointment average (whole service) was about 14 before CAPA. In one team after CAPA it had fallen to around 9.

It can be hard to work out the average number of appointments but a rough guide is to audit the next 20 attendees for that Specific Partnership pathway and note which appointment it is i.e. 1st, 7th, 3rd, 22nd etc. The average number of appointments for those 20 attendees is roughly the average for a complete intervention. This is because extra appointments of those continuing are offset by those who have already been discharged.

You can work out the multiplier for Specific Partnership using the same maths:

Multiplier = Appointments per half day x 11.25 (weeks available) / average number of appointments.
