User Satisfaction Survey


In February / March 2020, we sought feedback from clinicians who referred patients to our service in 2019. We are delighted to report that 83% of clinicians, rated their overall satisfaction with our service as either 9 or 10/10 (termed a top box score). This is an 8% increase in overall satisfaction, compared to the 75% score in 2019.

Based on previous feedback, over the past year, we have focused on streamlining our referral process and have introduced a single phone number for referrals. In 2021, we will streamline our referral process further, with the introduction of web-based referral forms. 

We would like to thank all clinicians that responded to the survey, your feedback is invaluable in helping to steer the future direction of Therapeutic Apheresis Services.
