Artificial intelligence (AI) and machine learning (ML) are becoming more common in medicine. They help with tasks like looking at medical images and handling office work. These tools can improve healthcare and make it run more smoothly. But one problem is called temporal bias. This means AI models lose accuracy over time as medical knowledge and practices change.
People who run medical clinics and manage IT in the United States need to know about temporal bias. They must update and check AI systems often. This article explains what causes temporal bias, why we must keep AI updated, and how AI can help with daily work in healthcare.
Temporal bias happens when AI systems use old data and stop working well because medicine has changed. For example, an AI trained years ago on patient info or treatments may not predict well today.
Things that cause temporal bias include:
If AI does not update for these changes, it can give wrong results. This can be risky for patients and make staff lose trust. AI might miss important signs or keep using old ideas that no longer help.
Healthcare changes fast. AI models should not stay the same over time. They need checking and updating often to work well.
Watching AI carefully avoids risks from temporal bias and other biases that appear when medicine or technology changes.
Researchers including Matthew G. Hanna have pointed out ethical problems from AI bias like temporal bias. If not fixed, the AI could give unfair or harmful advice to patients. Medicine changes, so old biased AI might treat some patients worse.
Healthcare providers must make sure AI stays fair and accurate. This needs cooperation between tech teams, doctors, and managers. They should review AI results against current medical rules.
Temporal bias is one of many AI biases. Others are:
Fixing temporal bias works best when these other biases are also managed well. This helps keep AI trustworthy.
Healthcare in the U.S. changes quickly because of new biomedical technology, new rules from groups like the FDA and CMS, and changes in patient groups. For example, there are more older people and illness patterns differ.
For those running clinics and healthcare technology, this means:
Therefore, healthcare groups should invest in tools and experts to keep AI checked and updated steadily.
AI is not just for medical decisions. It also helps with office work in healthcare places. For example, some companies use AI to answer phones and handle front desk work. This reduces the busy work of staff and helps patients better.
If AI for office tasks is not updated, temporal bias can make it work poorly. For example:
By updating AI models often, healthcare managers can keep office tools working well for patients and staff.
To handle temporal bias and use tools like AI phone systems effectively, healthcare leaders should:
AI can help make medical care more accurate and offices run better in the U.S. But ignoring temporal bias can make AI less reliable. This is true especially when clinical info and work procedures keep changing.
Clinic owners and managers who check and update AI often, and follow ethical steps, will get more benefit from AI. They will keep patient care safe and staff trusting these tools.
The primary ethical concerns include fairness, transparency, potential bias leading to unfair treatment, and detrimental outcomes. Ensuring ethical use of AI involves addressing these biases and maintaining patient safety and trust.
AI-ML systems with capabilities in image recognition, natural language processing, and predictive analytics are widely used in healthcare to assist in diagnosis, treatment planning, and administrative tasks.
Bias typically falls into data bias, development bias, and interaction bias. These arise from issues like training data quality, algorithm construction, and the way users interact with AI systems.
Data bias stems from unrepresentative or incomplete training data, potentially causing AI models to perform unevenly across different patient populations and resulting in unfair or inaccurate medical decisions.
Development bias arises during algorithm design, feature engineering, and model selection, which can unintentionally embed prejudices or errors influencing AI recommendations and clinical conclusions.
Yes, clinic and institutional biases reflect variability in medical practices and reporting, which can skew AI training data and affect the generalizability and fairness of AI applications.
Interaction bias occurs from the feedback loop between users and AI systems, where repeated use patterns or operator behavior influence AI outputs, potentially reinforcing existing biases.
Addressing bias ensures AI systems remain fair and transparent, preventing harm and maintaining trust among patients and healthcare providers while maximizing beneficial outcomes.
A comprehensive evaluation process across all phases—from model development to clinical deployment—is essential to identify and mitigate ethical and bias-related issues in AI applications.
Temporal bias refers to changes over time in technology, clinical practices, or disease patterns that can render AI models outdated or less effective, necessitating continuous monitoring and updates.
