Predictive analytics in healthcare: 7 ways to save time and money

Unlike traditional approaches to analytics that simply present processed information from the past, predictive analytics uses historical and real-time data to forecast future events and identify trends in patient care. To achieve this, predictive analytics employs a variety of techniques and technologies, including data mining, statistics, artificial intelligence (AI), generative AI (Gen AI), and machine learning (ML).

Simply put, predictive analytics solutions answer the question: what can possibly happen next?

Healthcare predictive analytics aggregates vast amounts of patient data incoming from electronic health records (EHR), insurance claims, administrative paperwork, medical imaging systems, etc. and processes it, searching for patterns.

With predictive analytics, healthcare providers get to answer the following questions:

Here are some examples of how healthcare leaders can benefit from predictive analytics:

Predictive analytics is transforming the medical field in multiple ways. Here are seven exciting predictive analytics use cases in the healthcare industry:

The costs of hospital readmission are rather high. The US healthcare system spends around $52.4 billion on readmissions per year. Additionally, hospitals are subject to heavy penalties under Medicare’s Hospital Readmission Reduction Program, which adds financial incentives to combat readmission. As research shows, 82% of hospitals in this program received this type of penalty.

Healthcare predictive analytics can identify patients with traits indicating a high possibility of readmission so that doctors can allocate additional resources for follow-ups and personalize discharge protocols to prevent a quick turnaround..

Real-life example of predictive analytics in healthcare:

A research team at Corewell Health deployed AI and predictive analytics in healthcare to identify patients with a high probability of readmission. The researchers studied the patients who had a hard time recovering after hospitalization and devised a recovery plan.

This plan had three pillars: behavioral health, clinical challenges, and social determinants of health. As soon as the predictive analytics tool spotted a potential candidate for readmission, an interdisciplinary team worked with the person to address those three aspects. This approach enabled Corewell Health to prevent the readmission of 200 patients and save $5 million in associated costs.

Medical research institutions rely on predictive analytics for managing population health. This technology can help spot different public behavioral patterns and forecast how they can impact health. For instance, a study from the Lancet Public Health journal found that unless alcohol consumption patterns change in the US, alcohol-related liver diseases will rise, causing deaths.
Furthermore, predictive analytics can detect disease outbreaks at early stages, giving governments time to prepare.

Real-life example of predictive analytics in healthcare:

When speaking of outbreak predictions, one can’t help but ask, “Could predictive analytics have foreseen the COVID-19 pandemic?” The answer is yes. BlueDot, a Canadian company building predictive analytics and AI solutions, issued a warning about the rise of unfamiliar pneumonia cases in Wuhan on December 30, 2019. Only nine days later, the World Health Organization released an official statement declaring the emergence of the novel coronavirus.

According to the HIPAA Healthcare Data Breach Report, cyberattacks are frequent in the healthcare sector. The report revealed that medical data breaches affected over 23 million people within the first five months of 2025. For instance, in May 2025, the healthcare sector experienced 60 data breaches, each one affecting over 500 people. The graph below demonstrates the statistics for one year.

Cybersecurity predictive analytics in healthcare can positively contribute to this situation. Healthcare organizations can use predictive analytics coupled with artificial intelligence solutions for the medical sector to calculate risk scores for different online transactions in real-time and respond to events based on their scores.

For example, during a login event, the system will grant access to a low-risk process and block a high-risk process or challenge it for multi-factor authentication. Furthermore, predictive modeling in healthcare can monitor data access and sharing to identify any changes in patterns, which could indicate an intrusion.

Real-life examples of predictive analytics in healthcare:

A major US hospital narrowly avoided a large-scale ransomware attack when its AI-powered predictive analytics system detected suspicious activity within 2.3 seconds, neutralizing the threat before any breach occurred.

Milton Keynes University Hospital uses a self-learning AI to monitor normal behavior across its digital systems. By detecting subtle deviations early—like ransomware or insider threats—it predicts and stops attacks before they escalate. As a result, this system provides 24/7 autonomous attack response, fewer false alerts, and reduced downtime.

Hospitals can use machine learning for disease prediction in healthcare when patients don’t show any visible signs or even tendencies for onsets.

Real-life examples of predictive analytics in healthcare:

A research team experimented with predictive analytics models in healthcare to identify patients with early onsets of diabetes. The scientists used medical data from Hospital de Santa Luzia and found that it was possible to build a reliable ML model using patient profiles and the prescribed medication the person has been consuming.

In another example, a research team built an ML-powered tool that can predict multiple myeloma. This solution takes into account tumor genomics and the prescribed treatment. During the course of this project, researchers identified 90 genes that can be present in a tumor and have a high potential for mutation. With this knowledge, the tool could predict 12 different types of multiple myeloma.

In yet another research project, the University of Massachusetts just recently started its initiative to build a deep learning model that can predict Alzheimer’s as early as two years before the first symptoms start showing.

You can find more information on similar experiments in our ML in bioinformatics article.

Predictive analytics in healthcare can spot insurance claims that are likely to be denied based on historical data and rejection patterns. The technology can also detect insufficient reimbursement codes and suggest matching fields. Such tools can help hospitals prepare insurance claims faster while minimizing errors.

Real-life predictive analytics in healthcare example:

In a recent study, researchers applied machine learning to predict healthcare insurance claim denials. Their AI model identified high-risk claims in real time, enabling managers to intervene early. Ultimately, it reduced rejection rates by 25% in just six months.

Suicide is the tenth leading cause of death in the US, taking the lives of 14 Americans out of 100,000 annually. AI-powered predictive analytics for suicide prevention can factor in a patient’s previous attempts, medical notes, and social and economic conditions to determine the likelihood of future attempts.

Predictive analytics in healthcare: examples from real life:

A research team at the Vanderbilt University Medical Center (VUMC) developed a predictive analytics model that uses patients’ electronic health records to forecast the likelihood of suicide attempts by particular patients. The tool was tested at VUMC for 11 months. While doctors were receiving patients, the algorithm was running in the background, predicting the risk of patients returning for attempted suicide treatment.

This predictive analytics in healthcare tool classified patients into eight groups based on their estimated risk factors. The VUMC research team noticed that the highest-risk group accounted for over 33% of all suicide attempts. The team concluded that anyone who is placed into the high-risk groups should be checked for suicidal tendencies.

In another example, scientists applied predictive analytics in healthcare to detect suicide ideation and suicide attempts in South Korean adults. They achieved high accuracy when analyzing factors such as income, self-esteem, and depressive symptoms.

The US healthcare system is losing about $150 billion per year on appointment no-shows, not to mention the associated administrative burden. For individual practitioners, the costs are averaging $200 per missed appointment. Predictive analytics in healthcare can improve cost efficiency by allowing hospitals and private clinics to forecast which patients are likely to skip appointments without prior notice. Consequently, they can prevent revenue loss and increase provider satisfaction.

Real-life example of predictive analytics in healthcare:

A team of researchers cooperated with Doctor Luis Calvo Mackenna Hospital, a pediatric facility in Chile, which reported a high no-show rate of 29%. The researchers used healthcare predictive analytics and ML to process patient data, such as demographics and social conditions, to spot patients prone to no-shows and call them with a reminder. During the eight-week experiment, the researchers managed to reduce no-shows by 10.3%.

Predictive analytics in healthcare comes with risks that medical facilities must address to fully realize its potential. Here are the key challenges to consider:

Healthcare providers are finding themselves in constant need to advance their computer skills. And with predictive analytics, they will not only need to access dashboards but also keep capturing and processing patient data. It can be hard to find the balance between patient care and data collection during appointments.

To overcome this challenge, medical facilities can involve their staff in the development of predictive analytics tools in healthcare and incorporate their feedback.

As Oscar Marroquin, Chief Clinical Analytics Officer at the University of Pittsburgh Medical Center, stated, “Being able to win acceptance of your models by clinicians—who are skeptics by nature—is often a challenge. By making end-users part of the whole process, we’ve been able to overcome that in the majority of cases.”

People are more likely to engage in risky behavior when they know someone’s got them covered. This is what we observe in healthcare settings where some doctors may rely excessively on predictive analytics for decision-making, under the assumption that these tools bear the responsibility for outcomes.

To mitigate this risk, it’s crucial to emphasize that decisions made by analytical tools are not definitive mandates but rather recommendations. Clinicians must critically evaluate these suggestions and, if needed, involve patients in the decision-making process.

There are several types of algorithmic bias that can affect a model’s performance on particular datasets. For example, algorithms can “learn” to treat race as a biological factor. Research shows that some diagnostic models require Black patients to show worse kidney function or Asian patients to experience more severe lung damage to access the same treatments as White patients.

What makes things harder is that there are no explicit regulations governing algorithm development. At the moment, the responsibility of producing fair tools falls on the vendor’s shoulders.

To reduce the risk of bias, vendors can use feedback loops to improve their tools and eliminate any bias that still gets in. Also, organizations that are using predictive analytics in healthcare need to conduct regular audits and implement the human-in-the-loop approach to make sure the algorithms are still relevant and bias-free.

Many powerful healthcare predictive analytics models have a black-box architecture, meaning they don’t explain how they produce their output. This approach is acceptable in administrative matters, such as predicting which insurance claims will be declined. But doctors will not take any recommendation that affects patients’ well-being without understanding the motives.

As a solution, clinics can look into explainable AI to cover the use cases directly impacting people’s health.

The global healthcare predictive analytics market was valued at $14,579 million in 2023 and is expected to reach $67,255 million by 2030, growing at a CAGR of 24.4%. It provides plenty of opportunities for healthcare providers and health tech companies.

If you are a medical facility manager, search for ways to deploy predictive analytics at your organization and ensure doctors and executives are on board. If you are a health tech startup founder, make sure the algorithms you develop are fair and suitable for the targeted population segments.
