Care of Vulnerable Patients & Prevention of Iatrogenic Injury
Comprehensive Nursing Notes
Evidence-Based Practice for Nursing Students
Comprehensive approach to vulnerable patient care and safety
Table of Contents
Introduction
Vulnerable patients represent a critical population in healthcare who require specialized attention and care due to their increased susceptibility to harm, complications, and adverse outcomes. These patients face heightened risks not only from their underlying conditions but also from iatrogenic injuries—harm caused unintentionally by medical treatment or healthcare interventions.
As healthcare providers, nurses play a pivotal role in identifying, protecting, and advocating for vulnerable patients while implementing evidence-based strategies to prevent iatrogenic injuries. This comprehensive guide provides nursing students and practitioners with the knowledge, tools, and strategies necessary to deliver safe, effective care to vulnerable populations.
Learning Objectives
- Identify vulnerable patient populations and their unique risk factors
- Understand the concept and types of iatrogenic injuries
- Implement evidence-based prevention strategies
- Apply safety principles in clinical practice
- Develop competency in risk assessment and mitigation
Vulnerable Patient Populations
Vulnerability in healthcare refers to patients who have limited ability to protect their own interests due to physical, psychological, social, or economic factors. Understanding these populations is crucial for providing appropriate care and preventing harm.
High-Risk Populations
- Pediatric Patients: Developing organ systems, communication barriers
- Elderly Patients: Polypharmacy, cognitive decline, frailty
- Critically Ill Patients: Multiple organ dysfunction, complex treatments
- Immunocompromised Patients: Increased infection risk
- Pregnant Women: Fetal considerations, physiological changes
Special Considerations
- Mental Health Patients: Cognitive impairment, medication compliance
- Non-English Speaking: Communication barriers
- Socioeconomically Disadvantaged: Limited resources, health literacy
- Patients with Disabilities: Physical or cognitive limitations
- Emergency Patients: Time constraints, incomplete information

Understanding Iatrogenic Injury
Iatrogenic injury refers to harm, illness, or adverse effects caused by medical treatment, procedures, or healthcare interventions, rather than by the underlying disease or condition. The term “iatrogenic” comes from the Greek words “iatros” (physician) and “genesis” (origin), literally meaning “physician-caused.”

Prevention Strategies
Prevention of iatrogenic injuries requires a multi-layered approach incorporating evidence-based practices, system improvements, and cultural changes within healthcare organizations. The following strategies form the foundation of safe patient care.

Prevention strategies work like layers of Swiss cheese – multiple barriers prevent errors from reaching patients. When holes align, errors can occur, but multiple layers reduce this risk significantly.
Training, competency, vigilance
Communication, collaboration, checks
Alerts, automation, decision support
Policies, culture, resources
