Study Notes
Self-Monitoring of Blood Glucose (SMBG) in Diabetes Management
- Most blood glucose monitors can use blood obtained from alternative test sites, such as the forearm, and there are special lancing devices for patients with painful fingertips.
- Laboratory methods measure plasma glucose, and it is crucial for patients to know whether their monitor and strips provide whole blood or plasma results.
- Factors affecting SMBG performance include visual acuity, fine motor coordination, cognitive ability, comfort with technology, and willingness to use it, and cost.
- Some meters are available for patients with visual impairments, and some can check both blood glucose and blood ketone levels for DKA susceptibility.
- 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- Common sources of error in SMBG include improper application of blood, damage to reagent strips, use of outdated strips, and improper meter cleaning and maintenance.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 an important role in providing initial education about SMBG techniques and evaluating the techniques of experienced patients.
- SMBG is a useful tool for managing self-care for everyone with diabetes and is a key component of treatment for intensive insulin therapy and diabetes management during pregnancy.
- For most patients who require insulin, SMBG is recommended two to four times daily, usually before meals and at bedtime.
- Patients are asked to keep a record or logbook of blood glucose levels to detect patterns, and testing is done at specific times to evaluate the need for dosage adjustments.
- Responding to SMBG results includes establishing baseline patterns, adjusting treatment regimens based on patterns, and contacting the primary provider when necessary.
- Patients using intensive insulin therapy regimens 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.
