Consider a patient’s comorbidities
Many patients with obesity have comorbidities, such as type 2 diabetes and hypertension, that can also be optimized for surgery so as to lower a patient’s overall risk profile. For patients with diabetes, achieving an A1c of 8% or lower can be a reasonable goal and can reduce risk. “We’ve found that an HbA1c level of 8% or less is something that virtually all diabetics (though not everybody) can reach, and it’s something that can be reached in a reasonable amount of time,” Dr. Giori said. Preoperative use of beta-blockers, continued use of ACE inhibitors or angiotensin receptor blockers, and behavioral modifications can improve a patient’s cardiac health before surgery.
Malnutrition can be a correctable problem for patients, regardless of BMI. In the Movement Is Life collection of optimization articles, experts recommend that orthopedists screen for malnutrition with blood tests for albumin, vitamin D, transferrin, and total lymphocyte count. Patients with malnutrition should be screened for food insecurity, experts advise, and surgical candidates with deficiencies can be given supplements of omega-3 fatty acids, arginine, and protein shakes.
Surgeon comfort and shared decision-making
Dr. Wiznia emphasized that the patient and surgeon need to discuss the risks of surgery, concerns about potential complications, and how a complication could affect the patient’s life moving forward. “Ultimately, the surgeon needs to make the decision [of whether or not to proceed [with surgery] with the patient,” he said, “but not every surgeon is going to feel comfortable operating on these patients, and not every medical institution is going to have the equipment and the investments to support surgeons doing it.”
Dr. Giori agreed that surgeons should proceed only with surgical cases they feel comfortable with. Certain surgeons may decide not to operate on individuals with higher BMIs because of the potential complications and can refer these patients to more specialized care centers. Operating on larger patients is more difficult and requires surgical skills and expertise that the surgeon may not have, he noted. “What I do object to is a system-wide BMI cutoff – for example, if an insurance company won’t pay for you to have a joint replacement, regardless of where you go or who your surgeon is,” Dr. Giori added. “I think that’s wrong, because it’s not patient centered and it’s basically excluding people from having a life-altering operation.”
Dr. Giori and Dr. Wiznia report no relevant financial relationships. Dr. Stronach is a consultant for DJ Orthopaedics, Johnson & Johnson, and MiCare Path.
