What Surgeons Leave Behind

Published on June 17th, 2014 by Michelle Hong Category: Patient Safety

The operating room is known as one of the most common locations for medical errors with one half to two thirds of all errors being attributed to surgical care. Due to the hectic and stressful setting of the operating room, medical professionals are more liking to lose track of surgical items including needles, scissors, retractors, and sponges. A report done by the National Quality Forum ranked lost sponges and instruments in the most serious category of medical errors. And each year, out of the 4,000 cases of retained surgical items that are reported, a majority of these retained items are sponges used throughout operations to soak up blood and bodily fluids. The consequences of such preemptive medical mistakes are unbearable on the lives of patients and their families.

Frightening enough, many patients carrying surgical sponges suffer for months or even years prior to any medical professional to discover the true root of the searing pain, digestive dysfunction, or nausea. Some victims lose parts of their intestines, while the lives of some unfortunate ones are sadly cut short. Erica Parks was a lucky survivor of a retained surgical sponge who openly expressed her story with USA TODAY. Parks’ felt that something was wrong with her belly after completing her cesarean section in 2010. Within the next month, her intuition proved to be right as she witnessed her stomach grew so swollen making her appear pregnant again. By week six, Parks’ bowels shut down completely resulting in a race to the emergency room. X-rays displayed a surgical sponge the size of a washcloth that was left behind inside of her abdomen. After an extensive day long emergency surgery to untangle the infected mass from her intestine, she was hospitalized for nearly 3 weeks. She continues to take medication to keep her digestion flowing and was told that there may be major repercussions if she tried to have another child.

Unfortunately, Parks’ case is one of many suffering from retained surgical instruments. Most often than not, by the time the preventive human error is determined, the infection has already set in causing chronic damage to the patient’s body.

According to a recent meta-analysis conducted on 19 studies found that simple interventions in the operating room such as checklists on teamwork, communication, and compliance with safety measures reduced morbidity and mortality by over 30%. Both simple and complex interventions are starting to be implemented to prevent such errors. For example, radio frequency tags that can be sewed into surgery tools have been used to curtail sponges that are unaccounted for. Patients are scanned at the end of each procedure to locate any remaining sponges.

Bill Adams of SurgiCount Medical stated, “Almost 50% of honor roll hospitals and academic centers now use bar-code technology to scan sponges as they go in and out of the patient as well.” Moving forward, it will be fascinating to see how technology can improve teamwork and communication,revolutionizing the way medical professionals keep patients safe.

Our Patient Safety Initiative

Published on March 7th, 2014 by Michelle Hong Category: Patient Safety

Medical accidents during hospital procedures continues to be one of the most prevalent health care issues of today’s society. According to the Institute of Medicine, medical errors in procedures estimated $17-29 Billion in direct costs to hospitals. And according to the Journal of the American Medical Association, medical errors result in 2.4 million extra days in the hospital nationwide. With the understanding that errors are unacceptable and costly to both patients and hospitals, chatr | health is taking immediate action to tackle this ongoing problem. Our team believes that there is no better time than now to take preemptive action steps to scale down the risk of accidents during procedures in order to keep patients safe and reduce hospital expenses.

We are dedicated to developing innovative mobile technology to achieve these outcomes. Our preemptive modules, algorithms, and safety checklists for inpatient providers prevent adverse events from happening. Cascadia, our mobile tool that is currently implemented into San Francisco General Hospital and UCSF Medical Center uses widely accepted evidence-based clinical guidelines to ensure appropriate steps are taken and essential tasks are not overlooked. In addition, our mobile tool operates during emergency code blues and emergent cardiac events to coordinate teamwork. Ensuring that the patient’s safety is the number one priority, Cascadia uses a specialized algorithm that is case and patient-specific. chatr | health takes our patient safety initiative very seriously and we are excited for other hospitals to join in saving lives one mobile checklist at a time.

chatr | health Teams with UCSF Medical Center: Patient Safety Initiative

Published on March 5th, 2014 by Michelle Hong Category: Collaborations

ChatrHealth is excited to team up with the University of California, San Francisco (UCSF) to officially launch our dynamic checklist modules and safety algorithms in all of the operating rooms of UCSF Medical Center. Leading the project is Dr. Jens Krombach, a UCSF anesthesiologist and Director of Perioperative Services at San Francisco General Hospital. Dr. Krombach has been passionate about leading implementation of checklists for normal, standard procedures for quite some time. Dr. Krombach states, “It’s important to use normal procedure checklist in the OR because providing anesthesia, even without complications, is more complex than flying a plane as errors and omissions happen on a daily basis.”

Our team is passionate about advocating innovative patient safety tools by working with the nation’s top industry leaders. According a recent study published the Journal of Patient Safety, preventable medical errors directly account for an estimated 400,000+ deaths per year, which according to the Center for Disease Control would be 3rd causes of death list. Preventable medical errors account for more deaths than diabetes, stroke, and pneumonia combined. Thus, chatr | health is excited to launch our preemptive mobile tools for inpatient providers keep adverse events like these from happening.

Cascadia, our dynamic checklist tools that incorporate preemptive modeling, is being launched in 13 operating rooms of UCSF Medical Center. The tool applies evidence-based clinical guidelines to recommend action steps and checklists to ensure appropriate steps are taken at the right time. In addition, Cascadia receives alerts to preemptively react and provides safer emergencies through organized task coordination. chatr | health is proud to be teaming up with nationally ranked hospitals to promote the adoption of patient safety initiatives and looks forward to future collaborations.
