Pioneering in digital prehabilitation with innovative medical solutions: the Prep4Surg App

Participating in prehabilitation programs can lower the risk of postoperative complications

The Prep4Surg will be a safe, easy to use data-efficient medical device class IIa and is currently under development and clinical testing.

Enhancing Surgical Outcomes: The Role of Prehabilitation

Postoperative complications after larger surgeries occur in 15 to 40% of patients and affect morbidity, mortality, the length of hospital stays and costs. Especially, the frail, elderly, and obese patients with a low cardiopulmonary reserve are at risk. Preoperative exercising for 3 to 6 weeks before surgery can boost the aerobic capacity and make patients more resistant to complications. Prehabilitation, which includes physical activity, optimized nutrition, and mental well-being amongst others, can contribute to patients readiness for surgery, reduce complication rates and optimize outcomes.

Easy handling. 6 steps to improved surgical outcomes

Step 1

Patient registration and data capture

A doctor or a medical assistant registers a new patient in the Prep4Surg app and captures basic patient data such as age, BMI, and gender. Subsequently, further relevant scores such as ECOG, TUG, RAI score, hemoglobin, resting heart rate, and heart rate-changing medication will be collected to define the initial risk assessment.

Step 2

Calculation of the Prep4Surg risk score and data transmission

Based on the collected data, the patient’s Prep4Surg risk score is calculated. All data, including the Prep4Surg risk score, is securely transmitted to the central cloud server to generate a risk dashboard and prepare the training program.

Step 3

Setting Up the
Training Program
in the Patient App

The patient gets access to the Prep4Surg app and is guided through the setup of their training program. This includes answering a quality-of-life questionnaire, performing the 6-minute walking test, and establishing a weekly exercise plan.

Step 4

Execution of
the Training
Program

The patient performs exercises at home according to the training program, monitored by the smartwatch. The smartwatch provides instructions based on baseline data to ensure the patient trains within the optimal heart rate range.

Step 5

Transmission of Training Data and Symptom Evaluation

After each training session, the smartwatch transmits the training data to the central cloud server. The patient also evaluates their symptoms in the app. This data is used for analysis and feedback. The doctor regularly reviews the patient’s progress in the doctor app and is notified through a push notification if the patient regularly misses their exercises or exceeds the set heart rate range.

Step 6

Doctor’s re-evaluation and program success measurement

The doctor perform a second risk assessment to compare initial data with post-prehab data.
