| 143 | == Primary Care Medication Coding |
| 144 | |
| 145 | After speaking to Stephanie Webb, I have gleaned the following information about primary care medication data: |
| 146 | |
| 147 | - It is extracted from System One and EMIS into the GEM data warehouse |
| 148 | - System One data is ''probably'' in Read Code format. |
| 149 | - EMIS is ''probably'' not, but don't know what format it is in. |

| 151 | == Patient Post Codes |
| 152 | |
| 153 | After speaking to Stephanie Webb, I have gleaned the following information about patient post codes data. |
| 154 | |
| 155 | - Post code data is not historic, only current post code data is recorded. |
| 156 | - GEM do not get post code data from the primary care IT systems, but get the information from the Exeter database. |
| 157 | - It may be possible to get the data from System One and EMIS, but this would involve an additional charge. |
