Failure to properly manage the perioperative period of patients is associated with increased morbidity and mortality. Preoperative evaluation in patients planned for surgery contributes to reviewing possible perioperative risks, optimizing the patient's functional and physiological status, and reducing the possibility of perioperative complications. Assessments made during the preoperative evaluation process can be used to educate the patient, organize resources for perioperative care, and formulate plans for intraoperative care, postoperative recovery, and perioperative pain management. However, the effect of preoperative evaluation on patient outcomes has not been clearly demonstrated. In this study, the effect of preoperative anesthesia evaluation on perioperative complications was investigated.

Not managing patients well before, during, and after surgery can lead to more health problems and deaths. In wealthy countries, 3-16% of patients face major issues during this time, and 0.4-0.8% of them might end up permanently disabled or dead. Checking patients before surgery helps identify risks, improves their health and fitness, and lowers the chances of problems during this period.

On another note, even though the right surgeries can save lives and prevent injuries, the growing cost of healthcare is a big issue worldwide. In the United States, the rising cost is a concern for everyone, including insurance companies and drug makers. It's believed that treatments that don't really help could be causing about 30% of these high costs.

No matter the surgery, patient's health, or anesthesia plan, checking patients before surgery is key to safe anesthesia for people of all ages. A thorough check before surgery helps manage patient care during this period, prevents surgery cancellations due to patient issues, and helps keep the surgery schedule efficient and cost-effective.

There's no agreed-upon definition for checking patients before anesthesia in medical literature. This check involves looking at the patient's medical history, interviews, physical exams, and test results. Anesthesiologists might also talk to other healthcare workers for more information or help with anesthesia care during this period. The information gathered can help educate the patient, plan for care during and after surgery, and manage pain.

However, it's not clear how much these pre-surgery checks actually improve patient outcomes. A recent study found that seeing a doctor before surgery didn't reduce, but actually increased, the chances of problems after surgery. This study looks at how well pre-surgery anesthesia checks at our center help prevent problems during this period
