Best Practices for Medication Administration and Monitoring
Block charting is an essential practice in the critical care and emergency department (ED) settings, where rapid decision-making and medication titration are necessary to respond to life-threatening situations. This practice is governed by organizational policies, which ensure both clinical effectiveness and legal compliance. Here’s an overview of how block charting functions, when it is utilized, and how to adhere to key standards for medication administration in these high-acuity environments.
What is Block Charting?
Block charting refers to the documentation of medications administered in discrete time intervals, known as "blocks." These blocks are utilized primarily in critical care and emergency situations where the administration of titratable medications requires precise monitoring and documentation. Block charting offers a structured way to track changes in medication dosages, the timing of those changes, and the physiological parameters that guide such adjustments.
Key Elements of Block Charting
In the critical care and emergency settings, block charting has specific requirements to ensure comprehensive documentation and patient safety. Each block of charting must include the following:
- Time of Initiation: The exact start time for the 4 hour period for block charting and the medication requiring titration.
- Medications Administered: The name(s) of all medications given during the block, including titration parameters, concentration, IV site, dose and rate.
- Maximum Rate (Dose): The maximum rate or dose administered during the block.
- Time of Completion: The exact time when the medication administration or titration concludes for the 4 hour block. A new 4 hour block will begin if the situation is appropriate for another block.
- Physiological Parameters: The key vital signs and lab results assessed during the block that guided the adjustments in medication.
- Starting and Ending Rates: The initial rate/dose and final rate/dose of medications administered during the block.
When to Use Block Charting
Block charting is not a substitute for verbal or written orders. It is typically used for medications that require rapid titration in response to fluctuating physiological conditions, such as vasopressors, sedatives, or inotropes. However, block charting is specifically reserved for situations where medications must be adjusted quickly, based on patient responses, and administered within a defined time frame.
Special Circumstances for Block Charting
- Single Block Duration ≤ 4 Hours: For any situation where medication titration and administration are necessary, block charting is utilized in time periods not exceeding four hours.
- Emergency Lasts > 4 Hours: If an emergency lasts longer than four hours, a new charting block must be initiated. This ensures that documentation remains accurate and manageable over time.
Importance of Organizational Structure in Block Charting
Develop a policy for block charting in urgent/emergent cases, standardize templates, train staff, integrating block charting flowsheet records seamlessly into the EHR. Consider enabling a tablet or other mobile platform to allow the nurse to be at the patient’s bedside and chart. Publish guidelines, and facilitate training for competency and assess feedback for continuous improvement.
