This is currently rolling out at Falkland Surgery.
In parallel to the screening day listed elsewhere we simultaneously arranged a mailshot program. 133 people were invited to the screening day and a random 133 people were invited to have a blood test for HbA1c and Blood Glucose.
133 people with a calculated QDiabetes 10 year risk over 15% were sent an invitation by post to have a blood test done over the next 4 weeks. A blood test form was included in the pack along with the calculated risk value and a short explanation of the process.
The outcomes desired were to screen those deemed at high risk of Diabetes (the County Show event suggested a 5% current risk in those responding), or borderline results needing follow up, and also assess the costs and impact compared to the screening day. (The mail-shot approach is much cheaper but needs to be evaluated against response rate)
Creating searches and templates 100
Mailshot to 133 people 50
Blood test costs 5 pounds per test (plus phlebotomy time) (total cost depends on response rate)
Medical time to evaluate returning bloods (included in general medical time within the practice estimated 3-15 results per GP)
133 letters sent out
36 blood tests completed within 4 weeks
1 Positive (raised) HbA1c results
5 Borderline results (HbA1c 42-47)
Therefore although less responses were triggered, the same numbers of postive results resulted as per the drop in day.
