What is predictive analytics in healthcare?
Simply put, predictive analytics solutions answer the question: what can happen next?
Predictive analytics in healthcare aggregates vast amounts of patient data incoming from electronic health records (EHR), insurance claims, administrative paperwork, medical imaging, etc., and processes it searching for patterns.
With predictive analytics, healthcare providers can figure out:
- Which diseases are patients likely to develop?
- How will they respond to different treatments?
- Will they be a no-show in their next medical appointment?
- Will they return to the hospital within 30 days of discharge?
“Combining these new datasets with the existing sciences of epidemiology and clinical medicine allows us to accelerate progress in understanding the relationships between external factors and human biology—ultimately resulting in enhanced reengineering of clinical pathways and truly personalized care.”

1. Preventing readmission
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.
How predictive analytics in healthcare reduces hospital readmission
UnityPoint Health, a network of healthcare facilities, wanted to understand why patients are being readmitted. They simply asked them, “Why do you think you are back?” The answers varied from not having the means to buy medication to not being able to book follow-up appointments. UnityPoint Health aggregated these answers into a predictive model that would assign a readmission risk score to every visiting patient.
A family physician, Patricia Newland, used the UnityPoint algorithm to prevent the readmission of one of her patients. The tool predicted this patient would experience symptoms during the next 13 to 18 days after discharge. Newland shared the results with her patient and instructed her to call the clinic as soon as the described symptoms appear. Sure enough, the patient called during the predicted time frame. Newland, who had already allocated time and resources, was able to see the patient on the same day and change her medication, thereby preventing readmission.
UnityPoint Health could reduce patient all-causes readmission by 40% within 18 months of deploying the predictive analytics tool.
Another example comes from Utah-based Health Catalyst, which provides data and analytics technology to the healthcare sector. The company developed a predictive health analytics solution to reduce readmissions. If you want to deploy their software, your data scientists will collaborate with the vendor to integrate your data into the program and establish a dashboard where medical staff can log in to see the likelihood of admitted patients developing a central line-associated bloodstream infection (CLABSI), which would ensure readmission.
Thanks to Health Catalyst, the University of Kansas Health System reduced their all-causes readmission by 39%.
2. Managing population health
Spotting chronic diseases with predictive analytics for healthcare
Predictive analytics in healthcare helps medical institutions identify people at risk of developing chronic conditions and give them preventive care before the disease progresses. This type of analytics assigns scores to patients based on various factors, including demographics, disabilities, age, and past patterns of care.
Diabetes Care published a study demonstrating that predictive analytics models for healthcare can determine a five to ten-year life expectancy for older adults with diabetes, enabling doctors to craft customized treatment plans.
Identifying public health trends with predictive analytics
Additionally, predictive analytics in the healthcare industry helps identify potential population health trends. The Lancet Public Health journal published a study that used predictive analytics to uncover health trends. This study found that unless alcohol consumption patterns change in the US, alcohol-related liver diseases will rise, causing deaths.
Detecting disease outbreaks with predictive healthcare analytics
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 novel coronavirus emergence.
To this day, predictive analytics in healthcare helps authorities and ordinary people to have a view on the pandemic. For instance, a research team at the University of Texas Health Science Center at Houston (UTHealth) developed a predictive analytics-based tool for COVID-19 tracking. This program produces and maintains a public health dashboard that shows current and future trends of the virus.
Shreela Sharma, Ph.D., and a member of the UTHealth research team outlined the benefits of this predictive analytics tool: “The dashboard identifies the current hot spots, predicts future spread both at the state and county level, and houses relevant public health resources. It can effectively inform decision-makers across Texas to help mitigate the spread of COVID-19.”
3. Enhancing cybersecurity
Predictive analytics in cybersecurity comes in two high-level types. Each has many subtypes of its own:
- Vulnerability-based solutions are searching for weaknesses in the healthcare system that can be exploited. These vulnerabilities range from misconfigurations to Common Vulnerabilities and Exposures (CVEs) that were not patched.
- Threat-focused platforms that look for potential threats.
4. Increasing patient engagement and outreach
Medical facilities can use predictive analytics in healthcare to engage patients and strengthen their relationships with physicians. These tools can help create patient profiles, send customized messages, and craft strategies that would be more impactful on each individual.
Lillian Dittrick, Fellow of the Society of Actuaries, said on the usage of predictive analytics: “When we use predictive models to look at all the variables, it helps us prioritize those patients who are really going to be receptive to changing something in their lifestyles, such as nutrition or exercise.”
Predictive healthcare analytics enable targeted marketing
Hospitals and pharmacies can use predictive algorithms to analyze patient data and identify dynamic customer personas with their distinct preferences and patterns. Afterwards, physicians can relate to these personas while planning targeted outreach messaging on, for instance, treatment adherence and drug efficacy. The marketing department can use these personas to craft their email campaigns.
5. Speeding up insurance claims submission
One example comes from Apixio. Headquartered in California, this company builds analytics-powered tools for healthcare. Apixio developed software that helps hospital coders to identify the correct codes for insurance claims. Those codes will determine how much insurance companies need to pay.
Traditionally, hospital coders sift through vast amounts of information to find the right codes. Apixio’s tool mines patient medical records for relevant data and presents hospital coders with the selected pieces that will help them determine the best code options.
6. Predicting suicide attempts
7. Forecasting appointment no-shows
Examples of predictive analytics for medical appointments no-shows
Some healthcare organizations are taking it a step further and reaching out to the patients with a potential no-show record to make sure they are fine and offer care remotely.
Community Health Network partnered with CipherHealth, a health tech company headquartered in New York, to deploy a data analytics solution that would reduce no-shows and facilitate patient outreach. With the new system in place, Community Health Networks can not only predict a no-show event but also reach out to the corresponding patient via their preferred means of communication (text, phone, email) to offer a brief remote consultation to satisfy the patient’s needs.
Predictive analytics surely benefits healthcare providers. But there are things to consider
- Gaining doctors’ acceptance. Healthcare providers are finding themselves in a 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 a challenge to find the balance between patient care and data collection during appointments.
- Ethics and moral hazards. One manifestation of moral hazard is that people are faster to take risks when they know they are insured. Some doctors may no longer put a lot of thought into making decisions as they believe predictive analytics is responsible for the consequences.
- Algorithm bias and lack of regulations. There are several types of algorithm bias that can impact predictive analytics’ performance on particular datasets. 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, and healthcare facilities are counting on the vendor’s goodwill.
