Summary of “Modulo 10.2 - Calidad en control de infecciones”

This comprehensive talk, delivered by Ana Lía Cristófano, head of the Infection Control Committee at the Italian Hospital of Buenos Aires, provides an in-depth overview of quality management in infection prevention and control within healthcare settings. The presentation covers the structure and functions of the infection control team, the nature and impact of healthcare-associated infections (HAIs), methodologies for quality management, risk assessment, and examples of continuous improvement cycles.

Main Ideas and Concepts

1. Introduction to Infection Control and Prevention Committee

The committee is an interdisciplinary team including doctors, nurses, infection control specialists, and epidemiologists.
Collaboration extends beyond the core team to clinical services, pharmacy, microbiology labs, maintenance, epidemiology, and institutional management.
The committee’s mission is to prevent healthcare-associated infections (HAIs) through safe, evidence-based practices.
HAIs are infections acquired as a result of care, not merely by being in a hospital; the term “hospital-acquired infections” is outdated.

2. Scope and Importance of Infection Control

Protects both patients and healthcare personnel by promoting safe environments.
Uses surveillance, data analysis, and continuous improvement to enhance care quality.
Promotes lifelong learning and institutional safety culture where every team member is responsible for prevention.
Areas monitored include multidrug-resistant organisms, surgical site infections, high-level disinfection, waste management, sharps safety, device reuse, and more.
Adheres to national and international regulations and evidence-based guidelines.

3. Healthcare-Associated Infections (HAIs)

Defined as infections occurring during patient care, not present at admission.
Common HAIs: catheter-associated bacteremia, ventilator-associated pneumonia, catheter-associated urinary tract infections, surgical site infections.
HAIs have higher prevalence in low- and middle-income countries (2-3 times more than high-income countries).
Consequences include increased morbidity, mortality (up to 30% or more depending on infection type), antimicrobial resistance, longer hospital stays, higher costs, and reduced patient trust.
Many HAIs are preventable with proper measures.

4. Quality Management in Infection Control

Applies principles and tools to prevent adverse events via safe practices, systematic monitoring, and continuous process improvement.
Key steps:
- Identify critical risk processes.
- Measure practices and outcomes with standardized indicators.
- Conduct clinical and observational audits.
- Analyze deviations and propose improvements.
- Implement interventions with follow-up and reassessment.
- Provide continuous feedback to teams.
Collaborates with quality, patient safety, epidemiology, and clinical leaders.

5. Epidemiological Surveillance

Fundamental for prioritizing risks and guiding interventions.
Infection rates are standardized per 1000 device or patient days to allow comparison over time and with other institutions.
Commonly monitored infections: central venous catheter bacteremia, urinary tract infections, ventilator-associated pneumonia, surgical site infections, and multidrug-resistant organisms.
Example given of ventilator-associated pneumonia rates showing significant reduction after years of targeted interventions.

6. Preventive Measures and Training

Use of “bundles” or packages of evidence-based care measures for device care (e.g., catheter care, ventilator care).
Training involves simulations and practical exercises.
Continuous review and updating of protocols based on new guidelines.
Monitoring adherence to bundles and correlating with infection rates to evaluate effectiveness.

7. Multidrug-Resistant Organism (MDRO) Management

Daily monitoring of patients with MDROs, isolation status, and potential suspension of isolation.
Medical records clearly indicate MDRO status and isolation precautions.
Rapid identification techniques (PCR, immunochromatographic tests) are used for timely detection.
Environmental hygiene is measured using fluorescent markers to ensure cleaning effectiveness, with results fed back to cleaning staff.

8. High-Level Disinfection and Device Traceability

Endoscopes and other devices that contact mucous membranes undergo strict high-level disinfection.
Cultures of devices are performed to detect contamination.
Interventions and training have reduced contamination rates.
Traceability systems track reuse of disposable devices, ensuring sterilization and monitoring usage to avoid risks.

9. Protected Environments for Vulnerable Patients

Special rooms for immunosuppressed patients (e.g., bone marrow transplant) with filtered, renewed air.
Portable HEPA filters used where positive pressure rooms are unavailable.
Also used for patients with airborne infectious diseases (e.g., tuberculosis, measles) to prevent spread.

10. Construction and Renovation Audits

Risk assessments are performed before construction projects.
Risk levels assigned based on location and patient population proximity.
Recommendations include dust control, sealing worksites, and daily monitoring during construction.

11. Education and Communication

Regular training for staff on hand hygiene, dress code, catheter care, and infection prevention.
Family and patient education about isolation and infection control.
Feedback to clinical services on infection rates and collaborative problem-solving.
Reporting to national health authorities and surveillance programs.
Staff protection through vaccination campaigns, notably annual influenza vaccination.

12. Biological Accident Management

Standardized reporting and management system for biological accidents.
Focus on training and retraining, especially for new residents and high-risk groups.

13. Risk Mapping and Prioritization

Uses a modified Kaiser risk model assessing:
- Probability/frequency of adverse events.
- Impact/severity of events.
- Institutional capacity to respond.
Risk maps guide prioritization of infection control activities.
Example priorities: hand hygiene sustainability, surgical site infections, multidrug-resistant organism transmission, catheter-associated infections.

14. Improvement Cycles Examples

Hand Hygiene Program

Recognized as the most critical measure to prevent HAIs.
Improvement plan includes training, measurement, feedback, verification, and strategy adjustment.
Measurement of the “five moments” of hand hygiene with direct feedback.
Use of patient feedback apps to monitor staff hand hygiene.
Dress code enforcement: uncovered arms, no rings/bracelets, proper nail care.
Use of fluorescent alcohol to demonstrate effective hand coverage.

Surgical Site Infection (SSI) Prevention

Detailed analysis of pre-, intra-, and post-surgical practices.
Standardized surgical bath protocols and joint nurse-surgeon checks before surgery.
Monitoring surgical prophylaxis (correct antibiotic choice, timing, dosage, duration).
Control of reuse of disposable devices with traceability and sterilization.
Monitoring surgical hand hygiene (duration, technique, absence of jewelry).
Environmental and procedural controls in operating rooms (door seals, pressure, clothing quality).
Limiting operating room personnel to reduce contamination.
Post-surgical care including drain management and blood glucose control.

15. Conclusion

HAIs are preventable through safe practices and team commitment.
Use of epidemiological data, risk assessment, and continuous education are key to success.
Infection control quality management is a continuous, team-based process involving measurement, analysis, and improvement.
Sustained improvements rely on interdisciplinary collaboration, leadership, and a strong safety culture.
