CAPA Demand and Capacity Modelling

Here is a slightly more technical description of a more ‘accurate’ demand and capacity model. To make it work in real life you will need really, really good data – which we certainly don’t have. The usefulness of it is that, if you find you are out of balance, then the model describes all the variables that might be contributing to this.

The Model

The demand comes from the hours you use in Choice and in Partnership Choice:

The number of referrals accepted
The number of clinical hours used in each Choice Partnership
The percentage of patients/users who transfer from Choice to Partnership
The average number of clinical appointments in Core Partnership and
The Percentage Co-therapy rate.

So Demand = Accepted Referrals x (Choice hours + Percentage transferring to Partnership x (Partnership hours x (1 + Percentage Co-therapy rate)))

TIP: note that if any of the above five variables increase the DEMAND increases

The capacity provided comes from:

The team FTE (full-time equivalent) in sessions (FTE x 10 sessions per FTE)
The percentage of that which provide Core Choice and Core Partnership time
The number of clinical appointments that can be provided per session
The percentage of each period of time that is actually worked (obviously less than 100% due to leave, study leave etc).

And so Capacity = FTE x 10 x Percentage capacity in Choice and Core Partnership x Appointments per session x % time worked

Note: again if any of the above decreases the CAPACITY decreases

So if the service is in balance then the demand will equal the capacity.

Simple! LOL!
