Problems finding patients

We received several reports that emergency ambulances had problems locating the patient, either because the postcode of the property was not precise enough or because the caller was unsure of the exact outside location they were at.
We spoke to West Midlands Ambulance Service and they explained the methods they use to locate patients, including using the what3words system if the caller has it installed on their mobile phone. However they were unable to tell us how often they had this problem. We have made the Shropshire Clinical Commission Group aware of the issue and the WMAS response to ensure that they are aware when they have their regular contractual meetings.
If you had similar experiences we would be keen to hear about them.
