Design outcomes
Primary
| Measure | Time frame |
|---|---|
| The Pharmacogenetic Clinical Utility Metric (Defined as the proportion of patients across the study cohort with a CPIC Level 1A variant related to the medicine which triggered recruitment to the study) – determined through genetic testing as part of study | — |
Secondary
| Measure | Time frame |
|---|---|
| 1. The proportion of patients recruited to the study who had their pharmacogenetic results returned within 10 working days (Monday – Friday) of enrolment. The day of enrolment represents day 0. Collected from patient records. 2. Average turnaround time from enrolment to PGx results being available on GPAS. Collected from patient records. 3. The proportion of enrolled patients whose GPAS system record was accessed by a member of the clinical team. Collected from patient records. 4. The proportion of participants who had a prescription issued before the pharmacogenetic results were available. Collected from patient records. 5. Average time from recruitment to prescription. Collected from patient records. 6. The proportion of patients who had at least one prescription amended over the course of the study based on the pharmacogenetic data. Collected from patient records. 7. Average turnaround time from enrolment to results being integrated into the Electronic Health Record (EHR). Collected from patient records. 8. Proportion of participants who have a delay (more than 10 working days) in results being integrated into the EHR. Collected from patient records. 9. The proportion of enrolled participants for whom a clinical decision support notification was triggered. Collected from patient records. 10. The average number of clinical decision support notifications which triggered over the course of the study (expressed as per month/visit/prescription). Collected from patient records. 11. The proportion of participants who had a prescription issued before the pharmacogenetic results were available. Collected from patient records. 12. The proportion of patients on a given class of medicine who had their index medicine (i.e., the medicine which precipitated recruitment) changed at 1 and 6 months following prescription. This outcome will be compared against anonymized historical (non-genotyped) comparators, matched for demographics, from the Greater Manchester Care Record | — |
