Common Types of Surgical Errors


Surgical procedures, while often life-saving and crucial for patient health, are not without risks. Among these risks are surgical errors, which can have serious consequences for patients. Understanding common types of surgical errors is essential for both medical professionals and patients to mitigate these risks and improve overall healthcare outcomes.

One of the most prevalent types of surgical errors is wrong-site surgery. This occurs when a procedure is performed on the wrong part of the body, such as operating on the left knee instead of the right. Despite protocols like preoperative marking and checklists, such mistakes continue to happen due to lapses in communication or procedural adherence among medical staff.

Another significant category is wrong-patient surgery. This error involves performing a procedure intended for one patient on another patient entirely. It often results from administrative mix-ups or misidentification during the preoperative process. The consequences can be devastating, leading to unnecessary surgeries for one patient and delayed treatment for another.

Retained surgical items represent another common type of error. These incidents occur when surgical instruments or sponges are unintentionally left inside a patient's body after the operation is complete. Such oversights can lead to severe infections, internal damage, and additional surgeries to remove the foreign objects.

Anesthesia-related errors also pose substantial risks during surgery. These errors can range from administering too much or too little anesthesia to using improper techniques that compromise patient safety. Anesthesia errors can result in complications such as prolonged unconsciousness, cardiovascular issues, or even death.

Infections acquired during surgery, known as surgical site infections (SSIs), are yet another concern. While not always categorized strictly as "errors," many SSIs stem from preventable factors such as improper sterilization of instruments or inadequate hygiene practices by healthcare providers.

Lastly, postoperative complications due to inadequate monitoring or follow-up care represent a subtle but critical form of error. Patients may suffer adverse effects if their recovery is not properly overseen-whether through neglecting vital signs monitoring or failing to recognize symptoms indicative of complications like internal bleeding or deep vein thrombosis.

Oakland, California

Oakland is a city in the East Bay region of the San Francisco Bay Area in the U.S. state of California. It is the county seat and most populous city in Alameda County, with a population of 440,646 in 2020. A major West Coast port, Oakland is the most populous city in the East Bay region, the third most populous city in the Bay Area, and the eighth most populous city in California. It serves as the Bay Area's trade center: the Port of Oakland is the busiest port in Northern California, and the fifth- or sixth-busiest in the United States. A charter city, Oakland was incorporated on May 4, 1852, in the wake of the state's increasing population due to the California gold rush.

Oakland's territory covers what was once a mosaic of California coastal terrace prairie, oak woodland, and north coastal scrub. In the late 18th century, it became part of a large rancho grant in the colony of New Spain, and was known for its plentiful oak tree stands. Its land served as a resource when its hillside oak and redwood timber were logged to build San Francisco. The fertile flatland soils helped it become a prolific agricultural region. In the 1850s, what became the first campus of the University of California was founded in Oakland, and Oakland was selected as the western terminal of the Transcontinental Railroad in 1869. The following year, Oakland's Lake Merritt became the United States' first officially designated wildlife refuge, now a National Historic Landmark. Following the catastrophic 1906 San Francisco earthquake, many San Francisco citizens moved to Oakland, enlarging the population, increasing its housing stock, and improving its infrastructure. It continued to grow in the 20th century with its port, shipyards, and manufacturing industry. In the 21st century, between 2019 and 2023, after the city and county refused requests for hundreds of millions of dollars in benefits to the privately owned teams, Oakland became the first city to lose three American professional major league sports teams to other cities within a span of five years.
