The Affordable Care Act has brought great change to the healthcare industry, and indeed to the medical device sector, driving interventionalists and surgeons to reflect on how value-based care models will affect their practices.
In a 2012 study, pre-operative, intra-operative and post-operative outcomes were collected on patients between 2009 and 2011 while they had inpatient general surgery procedures at an academic center (n=1,442).1 Thirty-day readmissions in this study were measured at 11.3 percent. At a recent Medical Development Group Boston meeting on the Internet of Things, the room was packed as several physicians presented multiple future clinical applications for wearable technologies, including the identification of patients at risk for surgical complications.2
Why It’s Important
The top three reasons for readmission in the study were gastrointestinal problem/complication (27.6 percent), surgical infection (22.1 percent), and failure to thrive/malnutrition (10.4 percent).
Can Wearables Prevent or Better Manage Readmission Rates?
Studies show that infections are a common cause of re-admissions. In the study, the top three procedures linked with higher readmission rates were pancreatectomy, colectomy, and liver resection.4 The post-operative events leading to an amplified readmission risk were blood transfusion, pulmonary and wound complications, sepsis/shock and urinary tract infection. For example, a recent study that followed patients after coronary artery bypass graft surgery (n=33,936) determined that 16.5 percent of patients were readmitted within 30 days of discharge and that the most common cause of readmission was post-op infection (16.9 percent).5
The study also notes the financial implications of hospital readmission.6 When a patient returns to the hospital, further limitations are placed on hospital resources. Every readmission means a lost opportunity to treat another patient, and places a burden on the healthcare system.
Sepsis and other forms of surgical infections, without intervention, can result in organ dysfunction and/or failure.7 For treatment to be successful, early identification of patients at risk and needing intervention is critical.8
This study delivers evidence that post-op complications are the single most significant risk factor causing hospital readmission. The analysis shows that any post-op complication increases average readmission risk by a factor of four. Patients with post-op sepsis or urinary tract infection (UTI) experienced increased readmission by a five-fold increase. Patients with post-op wound infections or post-op pulmonary complications carry a risk increase by a factor of approximately 3.5 (see Chart 2).
How Can Wearables Help Identify Post-Op At-Risk Patients?
If at-risk patients were discharged with wearables configured to monitor early conditions such as sepsis, outcomes might be improved.9 The Systemic Inflammatory Response Syndrome (SIRS), created by the American College of Chest Physicians and the Society of Critical Care Medicine is used to recognize patients suffering from early signs that may indicate an infection, such as sepsis.10
SIRS is defined when patients present with two or more of the following symptoms:

SIRS is defined when patients present with two or more of the following symptoms:
- Temperature greater than 100.4 degrees Fahrenheit or less than 96.8 degrees Fahrenheit;
- Heart rate greater than 90 beats per minute;
- Respiratory rate greater than 20 breaths per minute or an arterial partial pressure of carbon dioxide less than 4.3 kPa (32 mmHg); and/or
- White cell count above 12,000 cells/mm3 or less than 4,000 cells/mm3.
