ALT Each year, over 250,000 high-risk patients in the NHS face the prospect of major surgery, primarily older individuals with chronic conditions. Unfortunately, one-third of these patients undergoing surgery encounter medical complications, leading to enduring health and quality of life issues. Both physicians and patients often lack awareness of these long-term risks, resulting in inadequate information provision for decision-making. Shared decision-making is proposed to enhance informed treatment choices, yet little attention has been given to tailoring this approach for high-risk surgical patients. Recognizing this gap, researchers integrated findings from the OSIRIS program to develop a decision support tool. This tool provides pertinent long-term outcome data, supplementing routine care information. Through it, patients can prioritize outcomes relevant to them while also considering other essential factors.
