Surgical errors cover a variety of mistakes, such as operating on the wrong site, leaving instruments or sponges inside the body, anesthesia mishaps, and complications after surgery — all of which can cause serious harm to the patient.
Wrong-Site Surgery
Wrong-site surgery happens when a surgical procedure is performed on the incorrect part of the body, such as operating on the wrong limb or organ.
This serious medical error can lead to unnecessary harm to the patient, including additional surgeries, complications, and emotional distress. According to AHRQ-supported research, approximately 1 in every 112,000 surgeries is classified as wrong-site — though that figure is drawn from older surveillance data, and more recent estimates suggest the true rate is substantially higher due to voluntary-reporting gaps.
Wrong Procedure
When a surgical complication is referred to as a wrong procedure, it legally refers to a surgical intervention different from what was planned or indicated for the patient. This can result in unintended consequences and harm. A surgical team performing the incorrect procedure can result from miscommunication, inadequate preoperative verification processes, or failure to adhere to established surgical protocols.
Objects Left in the Body During Surgery
Retained surgical items — objects left in the body during surgery — can include surgical instruments, sponges, or other foreign objects inadvertently left behind in a patient’s body after a procedure.
Retained surgical items can lead to serious complications such as infection, pain, organ damage, and the need for additional surgeries to remove the retained items. This error occurs in every 5,500 to 7,000 surgeries, according to a study published by the National Library of Medicine.
Medication Errors
Medication errors during surgery are mistakes in the administration, dosage, or type of medication given to a patient before, during, or after a surgical procedure, potentially leading to adverse reactions, complications, or compromised patient safety.
Medication errors during surgery are reported to occur in approximately 1 in every 20 anesthetic administrations, as per a study published in Anesthesia & Analgesia.
Infections
Preventable infections happen when patients develop postoperative infections due to lapses in infection control measures, inadequate sterilization procedures, or breaches in surgical site hygiene. Surgical site infections occur in an estimated 2 to 5% of surgeries, varying based on the type of procedure and patient factors, as noted by the Centers for Disease Control and Prevention.
These infections can be the result of a surgical error, and they may lead to more extensive recovery times, increased healthcare costs, and potential complications for patients.
Preventable Falls During Surgery
These are defined as incidents where patients sustain unintended falls from the operating table or other surfaces during a surgical procedure, which can result in injuries such as fractures, head trauma, or complications related to anesthesia.
Anesthesia Errors
Anesthesia errors happen in approximately 1 in every 200 to 300 anesthesia cases, with major anesthesia complications happening in around 1 in every 10,000 to 100,000 cases, as reported by the American Society of Anesthesiologists.
They involve mistakes in the administration, dosage, or monitoring of anesthesia during a surgical procedure, potentially leading to complications such as respiratory distress, cardiovascular instability, or adverse reactions, endangering patient safety.
Nerve Damage
In the context of a surgical error claim, nerve damage refers to unintended injury or trauma to nerves during a surgical procedure, which can result in temporary or permanent loss of sensation, motor function, or chronic pain for the patient, potentially impacting their quality of life and requiring additional medical intervention for management.
Blood Clots
This type of surgical complication involves the formation of abnormal blood clots, known as thrombosis, as a complication of surgery, which can obstruct blood flow and lead to serious complications such as deep vein thrombosis (DVT), pulmonary embolism (PE), or stroke — posing significant risks to patient health and necessitating prompt medical intervention.
Injury to Adjacent Structures
This form of surgical error refers to unintended damage or trauma inflicted on nearby tissues, organs, nerves, or blood vessels during a surgical procedure, which can result from surgical instruments, manipulation, or inadequate visualization. An injury to adjacent structures can lead to complications such as bleeding, infection, or impaired function, and requires additional medical intervention for management.
Post-Operative Complications
Post-operative complications are adverse events or health issues that arise following a surgical procedure, such as infections, bleeding, or organ dysfunction. These can be potentially considered surgical errors when the type of complications indicates lapses in post-operative care or management.
Poor Wound Closure
When a poor wound closure results from inadequate technique, improper materials, or failure to address factors such as tension or contamination during the closure process, it may be considered a surgical error. Poor wound closures can cause complications such as wound dehiscence, infection, or impaired healing.
Failure to Obtain Informed Consent
When a patient undergoes a surgical procedure without fully understanding the risks, benefits, alternatives, and potential complications, it can be considered a surgical error. This is because their right to make an informed decision about their medical care is compromised. It can potentially lead to legal and ethical ramifications for the healthcare provider.
