The Use of Direct Oral Anticoagulants (DOACs) in Older Adults Receiving Multidose Drug Dispensing; Interactions, Anticholinergic and Fall-Risk Increasing Drugs

Key Takeaways for GI Nurses

• Older adults receiving multidose drug dispensing who are on DOACs face increased risks of drug interactions that can affect anticoagulation status and bleeding risk during endoscopic procedures
• Anticholinergic medications commonly found in multidose systems may compound cognitive and gastrointestinal side effects, potentially impacting procedural preparation and recovery
• Fall-risk increasing drugs combined with DOACs create a dual safety concern requiring enhanced pre-procedural assessment and post-procedure monitoring protocols
• Comprehensive medication reconciliation becomes critical when managing older adults on DOACs who receive pre-packaged medication systems

Clinical Relevance

This research highlights a growing concern for endoscopy units as the population ages and DOAC use expands. Older adults receiving multidose drug dispensing represent a particularly vulnerable population that requires enhanced nursing vigilance during the peri-procedural period. The presence of multiple medications that can interact with DOACs means that standard anticoagulation protocols may need individualized adjustments. GI nurses must be prepared to identify patients in this category during pre-procedural screening and collaborate closely with physicians and pharmacists to optimize timing of DOAC cessation and resumption around procedures.

The intersection of anticholinergic burden and fall-risk medications in this population creates additional nursing challenges. These patients may experience increased confusion, dry mouth affecting bowel preparation compliance, and mobility issues that complicate safe ambulation post-procedure. Endoscopy units may need to develop specialized protocols for managing these complex patients, including extended observation periods, enhanced family communication, and modified discharge criteria. Staff education on recognizing drug interaction warning signs and fall prevention strategies becomes essential for maintaining patient safety standards.

From an operational perspective, this research underscores the importance of robust pre-procedural assessment protocols and interdisciplinary communication. Units may need to allocate additional time for medication review and coordinate more closely with pharmacy services to ensure optimal anticoagulation management. The complexity of these cases may also influence scheduling decisions and staffing considerations, particularly for higher-risk procedures.

Bottom Line

Older adults on DOACs who receive multidose drug dispensing represent a high-risk population requiring enhanced nursing assessment and monitoring in the endoscopy setting. GI nurses must be prepared to identify potential drug interactions, assess anticholinergic burden, and implement comprehensive fall prevention strategies while managing anticoagulation protocols. This patient population demands heightened clinical vigilance, extended monitoring periods, and robust interdisciplinary collaboration to ensure safe procedural outcomes and prevent adverse events related to polypharmacy complications.
