Why Blood Sugar Management Looks Different From One Operating Room to the Next

When you go into surgery with high blood sugar, your body faces extra challenges during recovery. Research shows that elevated blood sugar on surgery day increases the risk of infection, slower healing, and even death within 30 days—complications that doctors know how to reduce.

Yet hospitals across Canada aren't managing pre-surgery blood sugar the same way. Some anesthesiologists follow strict protocols; others don't. This inconsistency is a quality gap: patients should receive the same standard of care regardless of which operating room they enter or which doctor is managing their anesthesia.

A team at four academic hospitals in Alberta wanted to understand why this gap exists. They interviewed 13 anesthesiologists one-on-one, asking them directly about how and why they manage blood sugar before surgery.

To make sense of the answers, researchers used two frameworks designed to identify barriers and drivers of clinical practice—tools that look at everything from how doctors remember guidelines, to what they pay attention to, to how their workplaces support (or don't support) best practices.

The study found clear differences in how anesthesiologists approach pre-surgery blood sugar. Some doctors delay surgery if blood sugar is too high; others do not. Some actively manage glucose during the procedure; others prioritize other factors.

These differences didn't come down to disagreement about facts. Instead, the researchers identified variation in memory (whether doctors recall guidelines), attention (whether they focus on blood sugar levels), and decision-making processes (how they weigh the importance of blood sugar against other concerns).

The research also highlighted the role of goals—different anesthesiologists may have different priorities when planning care, and these priorities shape their clinical choices.

If you have Type 1 diabetes and face surgery, your blood sugar management that day can influence your recovery. This study suggests that the quality of care you receive may depend partly on which anesthesiologist is in the room—not because they're less skilled, but because the field lacks standardized, widely adopted protocols.

The research included a patient partner with Type 1 diabetes who had undergone surgery and participated in designing the study and analyzing results. Their perspective helped ensure that the questions asked were relevant to people who actually live with diabetes and face surgery.

Identifying a gap is the first step toward closing it. By understanding why anesthesiologists approach pre-surgery blood sugar differently—not as a failure on their part, but as a knowledge translation problem—hospitals and professional organizations can design better guidelines, training, and support systems.

The hope is that this research will eventually help ensure that every patient, regardless of where they have surgery or who manages their anesthesia, receives evidence-based care to keep their blood sugar in a safe range on surgery day.
