How good are we at advising appropriate patients with glaucoma to inform the DVLA? A closed audit loop

To establish how good we are as clinicians at advising glaucoma patients with bilateral visual field defects of their legal responsibility to inform the Driver and Vehicle Licensing Agency (DVLA). By using a sticker placed in the patients' notes to highlight driving status and visual fields, we sought to improve our success in providing and documenting this advice.

We interviewed and examined the notes of two groups of 100 consecutive glaucoma patients before and after the introduction of a 'driver sticker' placed into patients' notes at the time of visual field testing. We examined the documentation of driving status, and the provision and documentation of advice regarding the DVLA.

In the first audit, we found only 9% of patients had driving status documented. Only 20% of drivers with bilateral field defects were advised to inform the DVLA with 11.4% documentation of this advice. After the introduction of the sticker, we succeeded in improving the documentation of driving status to 99%. We advised and documented the advice to inform the DVLA in 97% of drivers with bilateral field defects.

We found that as a unit we were poor at documenting driving status and advising glaucoma patients with bilateral field defects to inform the DVLA. By the simple measure of introducing a sticker into patients' notes, we were able to highlight this critical group and improve our provision and documentation of appropriate advice regarding informing the DVLA.
