Clinical Judgment Key for Suicide Prevention

Article excerpt


ANNAPOLIS, MD.-Numerous suicide risk-assessment tools are available, but because none are perfect, the ability to prevent inpatient suicide hinges on a single factor, according to Dr. Robert P. Roca.

"It all comes down to clinical judgment. How do we guide clinical judgment?" Dr. Roca, vice president of medical affairs at Sheppard and Enoch Pratt Hospital, Towson, Md., asked at the meeting. Basically, "it's a synthetic clinical judgment that involves taking into account a whole lot of factors, and there's really no test that tells us reliably what the answer is to this person's risk."

About 5 years ago, Dr. Roca said, the Sheppard Pratt Health System looked retrospectively at its experience with inpatient suicide in its family and inpatient programs

They found that men and women are equally likely to make serious attempts. Interestingly the elderly were not disproportionately at risk. Nearly half of attempts occurred in the first 3 days; however, some attempts occurred when a patient appeared ready for discharge.

Most patients who made serious attempts at suicide had unipolar or bipolar depression. Importantly, patients usually attempted hanging from a bedroom or bathroom door using bed linens or clothing.

Because attempts occur most often in bedrooms and bathrooms, careful design is needed to eliminate many hazards, such as using breakaway fixtures or down-sloping fixtures and avoiding breakable glass materials. "But a door is a potential gallows ... that was the vivid message that came across," he said. However, self-asphyxiation does not require hanging, and practically anything can become an instrument of self-harm.

"The most important message for me was that people who attempted suicide didn't warn you in advance that they were going to do that," Dr. Roca said. "Certainly, a safety contract is no guarantee of safety."

Based on careful review of the records of patients who succeeded in committing suicide as an inpatient, the researchers identified several salient features of the mental status of these patients. These included intense psychological pain or anguish, intense self-loathing, delusions of guilt, agitation or perturbation, hopelessness, and a feeling that death would bring relief.

Universal precautions for these patients might include a physical environment that is safe yet therapeutically warm and a clinical milieu that inspires hope and rapidly relieves psychological distress, he said.

"You also need to be able to identify people who are at very, very high risk" and require special risk assessment. Early scales were simply inventories of demographic risk factors with limited evidence of reliability or validity. Subsequent scales were better researched, and included scales-such as the Beck Scale for Suicidal Ideation-with good reliability and validity but poor predictive value. Other scales were lengthy research tools that were impractical for clinical use and not designed to evaluate immediate risk.

More practical tools are available, but these are not perfect, either. The Nurses' Global Assessment of Suicide Risk is a 15-item nurse-rated checklist. Scoring gives special weight to hopelessness, an hedonia, recent bereavement, and prior attempts. On this assessment, greater scores call for higher levels of engagement.

The Positive and Negative Suicidal Ideation Inventory (J. Clin. Psychol. 2005;61:431-45) includes 14 items: eight "risk factors" and six "protective factors. …
