@username @username @username @username | However, to use the DSS effectively, GPs would need to adapt their consultation style, so that they code more information during rather than at the end of the consultation. This could be a potential barrier to adoption. Training GPs to use the system in a patient-centred way, as well as improvement of the DSS interface itself, could facilitate coding. | [5.0, 1.0, 1.0, 2.0] | Computer_Science | train | 1 | tweets | 883090072446349312 |
