In several places, Cliniko allows you to select a group of patients based on which practitioner or business they visited on their last (and sometimes next) appointment. This happens in the Referral Sources Report, in the Recalls Report, and when choosing patients to send a group SMS to. The operation necessary to find these patients was quite costly and could be very slow for clinics with many patients and/or appointments on record.
We've been wracking our brains for quite a while trying to make the experience faster and more pleasant for our clinics, and today we finally found a bug that was preventing some of our previous changes from taking effect. Now those three features could be up to 30 times faster for clinics with lots of data! If you never used them because they were too slow for you, give them a try now, and tell us how it goes!
