Study Notes
Self-Monitoring of Blood Glucose (SMBG) in Diabetes Management
- Most meters are biosensors that can use blood from alternative test sites like the forearm
- Special lancing devices are available for patients with painful fingertips
- Blood glucose monitors approved for patient use in the home and some test strips calibrate blood glucose readings to plasma values
- Plasma glucose values are 10% to 15% higher than whole blood glucose values
- SMBG methods need to match the skill level and physical capabilities of patients
- Some meters can be used by patients with visual impairments and have audio components
- SMBG is recommended for patients with unstable diabetes, severe ketosis, or hypoglycemia
- Frequency of SMBG varies based on insulin therapy, with 2-4 times daily recommended for most insulin-dependent patients
- Patients are asked to keep a record or logbook of blood glucose levels to detect patterns
- Testing is done at peak action time of medication and before and after meals
- Patients using intensive insulin therapy regimens may be instructed in the use of algorithms for changing insulin doses
- Baseline patterns should be established by SMBG for 1 to 2 weeks
