Development and Initial Psychometric Evaluation of a Postoperative Symptom Assessment Scale for Patients With Aneurysmal Subarachnoid Hemorrhage
This study successfully developed and validated a 19-item, four-domain Postoperative Symptom Assessment Scale for patients with aneurysmal subarachnoid hemorrhage, demonstrating strong psychometric properties including high reliability and validity for measuring multidimensional postoperative symptom burden.

When a blood vessel inside the brain bursts, it causes a sudden, severe event known as an aneurysmal subarachnoid hemorrhage. This is a medical emergency where blood leaks into the space surrounding the brain, often requiring surgery to stop the bleeding and repair the vessel. While modern medicine has become very good at saving lives during the immediate crisis, the journey does not end when the patient leaves the operating room. For many survivors, the recovery is long and complicated. They may escape death only to face a confusing array of lingering problems: headaches that won't go away, trouble remembering things, sensitivity to light, or a deep sense of exhaustion. For decades, doctors have relied on tools designed to check if a patient is awake or how well they can move their limbs. These tools are excellent for the acute phase, but they often miss the subtle, persistent symptoms that make daily life difficult once the patient is home. Without a way to measure these specific struggles, it is hard for doctors and nurses to know exactly what kind of help a patient needs to truly recover their quality of life.
A team of researchers at the Affiliated Hospital of Zunyi Medical College in China set out to fix this gap. They recognized that existing checklists were either too general or designed for Western populations, potentially missing symptoms that are particularly common or expressed differently among Chinese patients. To solve this, they spent months building a new, specialized tool from the ground up. They began by reading every relevant study they could find and then sat down to talk with fifteen patients who had survived the surgery. These conversations revealed details that medical records often overlook, such as a specific kind of fatigue or a heightened sensitivity to noise. The researchers combined these real-world stories with scientific literature to create a list of twenty-nine possible symptoms. They then brought in a group of nineteen experts, including neurosurgeons, nurses, and rehabilitation specialists, to review and refine this list. Through two rounds of careful discussion, the group narrowed the list down to nineteen essential questions that accurately captured the full range of postoperative struggles.
The resulting tool, called the Postoperative Symptom Assessment Scale for Patients With Aneurysmal Subarachnoid Hemorrhage, asks patients to rate how much they are bothered by specific issues, ranging from no trouble at all to symptoms that make them completely dependent on others. When the researchers tested this scale on 240 patients in a major hospital, the results were striking. The tool proved to be highly reliable; when the same patients were asked the same questions two weeks apart, their answers remained consistent, showing that the scale measures stable conditions rather than random fluctuations. The questions also grouped together in a logical way, revealing four distinct categories of symptoms that patients experience. One group included immediate, acute reactions like severe headaches, vomiting, or seizures. A second group covered sensory and mental tiredness, such as blurred vision, dizziness, and a lack of energy. A third group focused on difficulties with thinking and speaking, including slowed responses and trouble finding words. The final group addressed emotional and sleep issues, like irritability, agitation, and trouble sleeping.
The study found that this new scale is not just a list of questions but a scientifically sound instrument that captures the complex reality of recovery. The researchers demonstrated that the four categories they identified are distinct from one another yet deeply connected, reflecting how different parts of the brain and body interact during healing. For instance, the data showed that patients who suffered from chronic pain often also struggled with cognitive fatigue, suggesting that these problems are linked and should be treated together rather than in isolation. The scale successfully measured the burden of these symptoms with a high degree of accuracy, confirming that even patients who appear fully conscious and alert are often carrying a heavy load of moderate to severe symptoms that go unnoticed by standard medical checks.
This work represents a significant step forward in how medical professionals understand and treat survivors of brain hemorrhages. By providing a clear, culturally relevant way to measure these invisible burdens, the scale offers a path toward more precise and compassionate care. It allows clinicians to move beyond simply checking if a patient is alive and start asking how they are actually feeling. While the researchers note that the scale needs to be tested in more hospitals and with larger groups of people to confirm its usefulness everywhere, the initial findings are strong. The tool offers a structured way to listen to patients, ensuring that their specific struggles are seen, measured, and addressed, ultimately helping them navigate the difficult path from survival to a full life.
