| Operating rooms | Between cases + daily | Terminal cleaning daily |
| Common areas | Daily minimum | Increase frequency during outbreaks |
Pests and Vector Control
Integrated Pest Management (IPM) programs are essential for preventing disease transmission and maintaining a safe healthcare environment:
- Implement inspection programs to identify potential pest entry points and harborage areas
- Establish barriers to prevent pest entry (sealing cracks, installing screens)
- Manage waste and food storage properly to eliminate attractants
- Use least toxic pest control methods as first line of defense
- Document all pest control activities for regulatory compliance
Key IPM Components
- Prevention: Building maintenance and sanitation practices to prevent infestations
- Monitoring: Regular inspections to detect early signs of pest activity
- Identification: Accurate pest identification to determine appropriate control methods
- Control: Implementation of mechanical, physical, biological, and chemical controls
- Evaluation: Ongoing assessment of program effectiveness
Temperature and Humidity Regulation
Appropriate temperature and humidity control in healthcare facilities protects patient safety, preserves medications and supplies, and maintains staff comfort:
- Maintain temperature ranges appropriate for specific care areas (68-73F general)
- Control humidity levels to prevent microbial growth (30-60% relative humidity)
- Implement temperature monitoring systems with regular calibration
- Establish contingency plans for HVAC system failures
- Maintain special requirements for medication storage areas
Temperature Guidelines by Area
| Area Type | Temperature Range | Humidity Range |
|---|---|---|
| Operating Rooms | 68-75F (20-24C) | 30-60% |
| Patient Rooms | 70-75F (21-24C) | 30-60% |
| Newborn Nurseries | 72-76F (22-24C) | 50-55% |
| Laboratories | 68-72F (20-22C) | 30-50% |
