Consistently inaccurate glucometer readings are a critical issue that demands immediate attention. This device plays a pivotal role in accurately detecting blood sugar levels, requiring precision in handling and proper storage. Even the slightest deviation from standard guidelines may result in inaccurate readings. Monitoring glucose levels in diabetic patients is crucial, as their medication and dosage depend on these readings and require close vigilance. The test strip must be dry and clean, and stored properly. Additionally, the patient’s hematocrit condition, habitat, amount of blood sample, and test strip quality also affect the reading. Errors in readings can be life-threatening. Therefore, understanding the causes of errors in glucometer readings is a highly relevant and crucial topic for many people worldwide.
Inaccurate Glucometer Readings
Man
- Failure to follow calibration instructions
- Improper blood application or timing
- Dehydrated diabetic patient
- Hematocrit variations/ low RBC count of the patient
Machine
- Inaccurate calibration
- Meter variances
- Old undercharged batteries
- Incorrect coding
Method
- Blood not taken from the fingertip
- Test strip partially inserted into the monitor
- Used sanitizer instead of soap/ water
- Hand and testing site not washed/ dried
- Presence of dirt/ alcohol/ other substances
Material
- Blood sample size not optimum/hemolyzed blood
- Test strip not meant for glucometer
- Damaged/outdated/ wet / contaminated test strip
- Strip not stored in a sealed container
Management
- Inadequate policies for calibration/ maintenance
- Insufficient training programs for users
- Lack of routine checks and maintenance
Environment
- Extreme temperature affects glucometer/ test strip performance
- Extreme high/ low temperatures affect the glucose level of the patient
- Inappropriate storage environment for glucometer/ test strip
- High humidity level
This RCA Fishbone diagram categorizes the potential root causes of inaccurate glucometer readings into six areas: human factors, equipment issues, processes, materials, management practices, and environmental factors. By systematically investigating these categories, stakeholders can identify and address the root causes to improve the accuracy and reliability of glucometer readings.
