Effects of Electrolyte Replacement Protocol Implementation in a Medical Intensive Care Unit

Area of Science:

• Critical Care Medicine
• Clinical Protocol Implementation
• Patient Safety & Quality Improvement

Background:

• Electrolyte abnormalities are common in critically ill patients.
• Timely electrolyte replacement is crucial for patient outcomes.
• Current electrolyte replacement processes may be inefficient.

Purpose of the Study:

• To evaluate the impact of implementing an electrolyte replacement protocol (ERP) in a medical intensive care unit (MICU).
• To assess if the ERP reduces the time to administer electrolyte replacement doses.
• To determine if the ERP improves provider satisfaction with electrolyte replacement.

Main Methods:

• Retrospective review of electronic medical records.
• Data collected before and after ERP implementation in an 18-bed military tertiary care MICU.
• Analysis of time from abnormal lab results to dose administration and provider satisfaction metrics.

Main Results:

• Significant reductions in median time to administer electrolyte replacement for potassium (180 to 98 min), phosphorus (190 to 135 min), calcium (95 to 61 min), and magnesium (155 to 149 min).
• Overall reduction in time to electrolyte repletion from 146 to 98 minutes (P < .01).
• Improved nursing satisfaction and an average of 4.4 minutes saved per physician per patient daily (P = .04).

Conclusions:

• Electrolyte replacement protocols can be safely implemented in the MICU.
• ERP implementation significantly decreases the time from abnormal laboratory results to electrolyte replacement.
• Protocols enhance provider satisfaction and reduce physician time spent on electrolyte replacement.
