Study Notes

Self-Monitoring of Blood Glucose (SMBG) in Diabetes Management

Most meters are biosensors that can use blood from alternative test sites, such as the forearm.
Special lancing devices are available for patients with painful fingertips or those who experience pain with fingersticks.
Laboratory methods measure plasma glucose, so most blood glucose monitors and test strips calibrate blood glucose readings to plasma values, which are 10% to 15% higher than whole blood glucose values.
Factors affecting SMBG performance include visual acuity, fine motor coordination, cognitive ability, comfort with technology, and cost.
Some meters have audio components to assist patients with visual impairments, and there are meters available to check both blood glucose and blood ketone levels.
Most insurance companies, Medicare, and Medicaid cover some or all of the costs of meters and strips.
Common sources of error in SMBG include improper application of blood, damage to reagent strips, use of outdated strips, and improper meter cleaning and maintenance.
Nurses play a crucial role in providing initial education about SMBG techniques and evaluating the techniques of experienced patients.
SMBG is recommended for managing self-care for everyone with diabetes, especially for intensive insulin therapy regimens and diabetes management during pregnancy.
For most patients requiring insulin, SMBG is recommended two to four times daily, usually before meals and at bedtime.
Patients are encouraged to keep a record or logbook of blood glucose levels to detect patterns and to evaluate the need for dosage adjustments.
Patients using intensive insulin therapy may be instructed in the use of algorithms for changing insulin doses based on patterns of values greater or less than the target range and the amount of carbohydrate to be consumed.
