What is the role for checking uric acid levels in evaluation of SIADH in hospitalized older adults?
Uric acid is typically not a first-line test for evaluation of hyponatremia. It's usually used when trying to differentiate between hypovolemic states (not SIADH by definition) and euvolemic states (including SIADH). The utility stems from how uric acid is handled in the nephron, i.e., it's reabsorb...
How do you decide between anticoagulation and observation for an incidentally detected subsegmental pulmonary embolism in elderly patients with a history of gastrointestinal bleeding?
We face this conundrum not infrequently because subsegmental emboli are subject to high inter-reader variability, and the accuracy of the finding in isolation is suspect (Batayneh et al., Blood 2023). I once mentioned this to a radiologist who reads CTAs and was told, tactfully, that I was full of i...
Are there any specific scenarios in which you calculate estimated creatinine clearance over eGFR in an older adult patient?
This would be something to consider for patients in which there is a discrepancy between clinical manifestations and creatinine estimated eGFR, for patients at the borderline of CKD stages, and for patients with extremes of muscle mass (which would lead you to think that the eGFR is less accurate). ...
How do you approach the choice of basal-bolus insulin vs correctional insulin alone to manage hyperglycemia in a hospitalized older adult with type 2 diabetes and significant frailty?
Frail older adults with type 2 diabetes, compared to their less-frail counterparts, may have less predictable oral intake, and you may have more difficulty obtaining an accurate medication reconciliation. You may need to review facility records or speak to multiple collateral historians to find out ...
How would you approach the consideration of continuing or ceasing colonoscopy for colon cancer screening in a relatively fit man in his 80s without a history of polyps on prior colonoscopies?
For someone in his 80s who has received good screening and never had polyps, continuing colonoscopy brings little benefit. The risks and difficulties from the procedure become greater with age, so, for most older adults, stopping routine screening is usually the better option for geriatric care. Whe...
Do you recommend vitamin K2 supplements in patients with osteoporosis?
The answer, as with most vitamin supplementations, cannot be answered with high-level evidence to support a "yes or no". A bit of background and then a brief review of available evidence.Vitamin K is thought to be important for bone health because it activates several proteins involved in bone forma...
What patient factors are most important when considering who needs a broader workup for osteoporosis prior to starting therapy?
A workup to rule out secondary causes must be done prior to starting therapy for osteoporosis. A good history and exam are recommended to look for any clues for modifiable factors. At a minimum, one should do CMP, 25-OH vitamin D, TSH, and a 24-hour urinary calcium or calcium/creatinine ratio should...
How would you approach the management of asymptomatic ALT and GGT elevation in an older adult patient with depression with psychosis and without history of hepatitis who recently had dose of quetiapine increased and new initiation of SNRI?
The answer when you suspect drug-induced liver injury depends on the X elevation above normal of ALT and bilirubin. In addition, exclusion of other coexistent factors, i.e., alcohol use, metabolic risks, or other medications. From liver tox, quetiapine may elevate liver tests in 30% of patients. Bel...
What treatment options are there for uremic pruritus in an elderly patient with risk of sundowning?
Uremic pruritus is increasingly recognized as a multifactorial condition involving peripheral neuropathy and immune dysregulation, particularly upregulation of type 2 cytokine pathways. Dysregulated opioid signaling further contributes to itch amplification. Accordingly, κ-opioid receptor agonists, ...
When considering deprescribing antihypertensives in older patients, how do you approach prioritization of which antihypertensives to target first?
When deprescribing antihypertensives in older adults, my approach is individualized, goal-concordant, and iterative with close monitoring after each step. Every patient is a little different, so there isn't one class of antihypertensives I always deprescribe first. My general rule of thumb is that w...
