New TB Screening Tool Reduces Unnecessary Isolation in Hospitals
Physicians at Massachusetts General Hospital (MGH) and Harvard Medical School have developed a groundbreaking TB risk scoring tool to enhance the assessment of suspected tuberculosis (TB) cases. This tool, integrated into the electronic health record system with the label “TB or Not TB,” is designed to help clinicians make accurate decisions about discontinuing isolation precautions once a patient’s test results are negative for TB. The system has been validated and is now in use across all MGH Bristol/Boston (MGB) sites.
The Urgent Need for Improved TB Screening
Recent years have seen a rise in TB cases in the United States, making it crucial for healthcare facilities to implement special precautions for patients with suspected TB. These precautions include the isolation of patients in specialized airborne infection isolation rooms. However, improper isolation can lead to workflow disruptions, reduced access to care, and decreased hospital capacity. There is a pressing need for efficient methods to accurately manage TB-risk patients while maintaining clinical safety and workflow efficiency.
Development of the TB Or Not TB Tool
A team of infection prevention experts, including physicians and researchers from MGH, developed the TB risk scoring tool by analyzing the records of past TB patients. This model assesses the likelihood of TB infection and guides clinicians in discontinuing isolation precautions when it is safe to do so. The team collaborated with clinical informatics and digital health developers to integrate this validated model into the electronic health record system, creating the user-friendly “TB or Not TB” tool.
This tool labels patients needing evaluation for TB as “TB-Risk,” which triggers the appropriate isolation and personal protective equipment use. Once the healthcare provider believes TB is not a concern, they can use the tool to determine if it is safe to end isolation.
Benefits of the TB Or Not TB Tool
The implementation of the TB Or Not TB tool has been found to have significant positive impacts on patient care and clinician workflows. In a comprehensive analysis of TB evaluations across the MGB system over six years, the tool accurately identified all TB-positive cases, ensuring these individuals remained isolated during their evaluation.
Additionally, the tool identified about a quarter of cases where TB was highly unlikely, allowing those patients to be released from isolation safely and efficiently. This approach can increase hospital bed capacity, reduce workload on healthcare providers, minimize consultation times, and improve the overall patient experience.
Supporting Patient and Healthcare Personnel Safety
The primary goal of the TB Or Not TB tool is to support patient and healthcare personnel safety. By ensuring accurate and timely isolation decisions, the tool helps prevent the spread of TB within healthcare facilities, reducing the risk of healthcare-associated infections and protecting both patients and staff.
Reducing Cognitive and Administrative Burden
The tool aims to减轻 the cognitive and administrative burden on clinicians. By automating parts of the assessment and decision-making process, healthcare providers can focus more on patient care and less on the time-consuming task of managing isolation protocols.
Enhancing Clinician Well-Being
Finally, the use of the TB Or Not TB tool can enhance the well-being of clinicians by streamlining workflows and reducing stress associated with infection control efforts.
Conclusion
The TB Or Not TB tool represents a significant advancement in TB risk assessment and management in healthcare settings. By accurately identifying cases of TB and safely discontinuing isolation for those who do not require it, the tool improves patient care, reduce workload on healthcare providers, and enhances overall safety. Its successful deployment across MGB hospitals showcases its potential to transform TB management practices in healthcare facilities nationwide.
With rising TB cases in the United States, the need for innovative solutions like the TB Or Not TB tool has never been more critical. As hospitals continue to refine their infection control strategies, this tool offers a practical and effective means of balancing patient safety and workflow efficiency.
