Case work: Brief vignettes
As well as being aware of the how effective different contraceptive methods are, it is important that we can inform women about which methods they should not use because of health risks. To help a woman decide on an appropriate contraceptive method it is necessary to take a full personal and family history, and to ascertain her blood pressure and body mass index.
An easy way to get help here is to look at the UK Medical Eligibility Criteria at the RCOG Faculty of Sexual and Reproductive Healthcare website
There is a full document but the summary sheets are useful for quick reference to answer the questions below
Question
Case 1. | A 38 year old woman who smokes 20 cigarettes/day. |
Case 2. | A woman with BP of 140/90. |
Case 3. | A woman with a personal history of deep venous thrombosis(DVT). |
Case 4. | Past history of pelvic inflammatory disease (PID). |
Case 1. | Because this woman is over 35 and smokes 20 cigarettes a day she cannot use the COC as she would be at an increased risk of cardiovascular disease.-category 4 She could use the POP, Depo Provera, as both category 1 |
Case 2. | Again because of BP she becomes category 3 for COC use and really should not use Could use POP, (cat 1) or Depo Provera (cat 2) |
Case 3. | Cannot use the COC because of the increased risk of thrombosis. (cat 4) POP and Depo Provera would be OK as both cat 2 |
