Modern surgery is safer than ever, yet a silent crisis is devastating elderly patients. In Episode 12 of the ReeThink Podcast, host Rudi Adigbli interviews John Klepper.

As the CEO and co-founder of PIPRA, John is tackling a medical complication more costly than diabetes. Together, they explore how artificial intelligence and digital therapeutics are finally identifying the patients most at risk of cognitive collapse.

John Klepper is a serial entrepreneur based in Zurich with a deep fascination for brain health and longevity. After a chance coffee with a neuroscientist, he pivoted from Alzheimer’s prevention to solving the “hidden” problem of Post-Operative Delirium. Under his leadership, PIPRA has developed one of the world’s largest harmonized databases on delirium. Consequently, John is now leading the charge to integrate predictive AI into surgical workflows across Europe and the United States.

Most people have never heard of Post-Operative Delirium. However, it is a leading cause of mortality and long-term cognitive decline in patients over 60.

• The Statistics: Delirium affects nearly one in four surgical patients in this age bracket.

• The Economic Impact: In the U.S., delirium is 60% more expensive to the healthcare system than diabetes.

• The Dementia Link: Suffering an episode of delirium increases the risk of developing permanent dementia by 1,400%.

Furthermore, nearly 70% of cases are missed because they are “hypoactive.” These patients are quiet and silent, while their brains suffer in a state of hallucinations and terror.

PIPRA’s risk prediction tool does not require new hardware or complex tests. Instead, it utilizes routine patient data that already exists within hospital systems.

• Automated Extraction: The AI sits behind the Electronic Health Record (EHR).

• Real-time Calculation: It analyzes age, BMI, medication history, and surgery type.

• Risk Stratification: The system provides a risk score (low to high) before the patient ever enters the operating room.

Therefore, nurses and anesthesiologists receive an immediate “alert.” This allows them to implement prevention protocols, such as early mobilization and hydration, to stop delirium before it starts.

Despite saving a medium-sized hospital roughly 11 million Swiss francs per year, adoption is slow. John explains that PIPRA is creating a new category of care. Because hospitals are resistant to change, MedTech innovators must endure a brutal validation gauntlet:

• Regulatory Certification: Proving safety as a certified medical device.

• Geographic Validation: Running studies in specific countries to satisfy local doctors.

• Cost-Effectiveness: Proving the staggering millions in savings to administrators.

The long-term vision for PIPRA is a world where patients leave the hospital better than they arrived. By combining predictive AI with digital therapeutics, John’s team is building a “Bio-Circular Economy” of surgical safety. Ultimately, they aim to solve all major hospital complications through data-driven intelligence.
