PETRUSHKA reveals that by combining the perfect out there proof with sufferers’ personal preferences, we will personalise antidepressant remedy from the outset and assist extra individuals within the NHS keep on the medicine that’s proper for them.”
The potential influence of PETRUSHKA is transformational. By enhancing remedy continuation and outcomes, the instrument might assist cut back the private, medical and financial burden of melancholy, notably in settings the place specialist psychiatric assist is restricted.
