This document summarizes the key aspects of the implementation guide for Centralized Surveillance Programs (CSPs) for Healthcare-Associated Infection (HAIs) Surveillance Programs in Acute Care Health Systems, published by the Association for Professionals in Infection Control and Epidemiology (APIC) in June 2025. The transition toward CSPs represents a strategic shift in infection prevention and control (IPC). Centralization leverages information technology and specialized personnel to standardize these identification processes, thereby increasing the validity of surveillance data and improving inter-rater reliability (IRR).

I. Introduction:
A Centralized Surveillance Program (CSP) consolidates the identification and reporting of HAIs into a dedicated team or automated system. This model replaces the traditional approach where individual IPs perform surveillance for their assigned units.
Objectives:
- Standardization: Applying uniform National Healthcare Safety Network (NHSN) definitions across all facilities within a system.
- Efficiency: Maximizing technology (EHR integration, data-mining tools) to identify potential infections.
- Resource Optimization: Allowing facility IPs to focus on IPC initiatives, policy creation, and clinical consultation.
The “Big Six”:
Surveillance typically focuses on:
- CLABSI: Central line-associated bloodstream infection.
- CAUTI: Catheter-associated urinary tract infection.
- SSI: Surgical site infection (specifically for colon procedures and abdominal hysterectomies).
- MRSA BSI: Methicillin-resistant Staphylococcus aureus bloodstream infection.
- CDI: Clostridioides difficile infection.
- VAE: Ventilator-associated events.
II. Comparative Analysis:
| Feature | Traditional Model | Centralized Surveillance Program (CSP) |
| IP Focus | Surveillance, reporting, and prevention | Prevention, rounding, and education |
| Consistency | Subject to individual interpretation | High standardization and IRR |
| Resilience | Burden increases during census surges | Surveillance continues during disasters/surges |
| Staffing | Harder to fill vacancies locally | Can leverage remote/outsourced labour |
| Risk | Manual errors in reporting | Risk of local IPs losing surveillance skills |
Weaknesses of CSP:
- Skill Decay: Local IPs may lose the ability to apply NHSN criteria if not practiced regularly.
- Disconnection: IPs may feel less aware of unit-specific clinical outcomes.
- Role Ambiguity: Nursing department may be confused about which staff member to consult regarding specific HAIs.
- Cross-training: Specialized roles can make staff coverage difficult if not properly managed.
III. Workforce:
Virtual/Remote Surveillance:
Virtual surveillance uses EHRs, microbiological results, and infection-related keywords to detect HAIs without a physical presence.
- Infrastructure Requirements: Secure data storage, EHR integration, and analytic tools are essential.
- Remote Management: Staff needs “office-like” home setup, including multiple monitors to avoid the need for printed patient information.
- Communication: Virtual teams require intentional, scheduled interactions (e.g., group chats and standing meetings) to prevent isolation and facilitate discussion on complex cases.
Outsourcing:
Facilities may outsource CSP functions to third-party vendors to manage the time-consuming burden of chart review.
- Benefits: Bridges gaps during IP vacancies
- Considerations: Organizations need to establish EHR access for them.
Competency and Training:
While Certification in Infection Control (CIC) is a gold standard, CSP staff may include “data abstractors” from non-traditional backgrounds (e.g., medical coding).
- Core Competencies: Proficiency in navigating EHRs and applying NHSN definitions.
- Ongoing Education: Mandatory participation in annual training, case studies, and internal IRR activities.
IV. Inter-rater Reliability (IRR):
IRR measures the agreement between different raters given the same data. It is critical for ensuring that healthcare outcome measures are credible.
Implementing IRR:
- Protocol: Use the NHSN Patient Safety Component (PSC) manual as the primary resource.
- Methodology: A percentage of cases (or “non-events” that were ruled out) should be “over-read” by a supervisor or peer to verify concordance.
- Threshold: Many programs set an agreement goal of >90%.
- Significance: Robust internal IRR prepares hospitals for external audits.
V. Future:
The profession is evolving toward a model where IPs act as “behavior modification experts” rather than data abstractors.
Emerging Strategies:
- Career Ladders: Creating entry-level surveillance roles (e.g., Infection Prevention clerk) to provide a “deeper bench” for future IPs.
- Behavioral Modification: Reclaiming 8–10 hours per week allows IPs to move beyond simple education and focus on why personnel do or do not comply with IPC standards.
- Specialized Certification: There is ongoing discussion regarding the development of a certification specifically focused on surveillance for personnel who do not hold a CIC.
