Reduction in chemotherapy order errors with computerised physician order entry and clinical decision support systems

Area of Science:

• Oncology
• Health Informatics
• Patient Safety

Background:

• Medication errors in chemotherapy are common, leading to adverse patient outcomes and increased healthcare costs.
• Chemotherapy protocol errors contribute to morbidity, mortality, re-admissions, and extended hospital stays.

Purpose of the Study:

• To evaluate if computerized chemotherapy ordering systems reduce the incidence and severity of chemotherapy protocol errors.
• To assess the impact of a clinical decision support system integrated with computerized ordering.

Main Methods:

• A prospective comparative study was conducted using computerized chemotherapy ordering (C-CO) versus paper-based ordering (P-CO).
• A custom-built C-CO system with decision support, standardized protocols, and automated processes was implemented.
• Clinical pharmacists validated orders, analyzed pharmacoeconomic data, and assessed medication error severity.

Main Results:

• The incidence of medication errors was significantly lower with C-CO (0.26%) compared to P-CO (2.4%).
• C-CO demonstrated high usability, clarity, and feasibility.
• Chemotherapy dispensing times were reduced, and overall chemotherapy costs decreased.

Conclusions:

• Computerized chemotherapy ordering with clinical decision support substantially decreases medication error rates and severity.
• The C-CO system improves chemotherapy dispensing and administration efficiency.
• Implementing computerized systems offers a cost-effective approach to enhancing chemotherapy safety and care.
