Do you recommend procalcitonin to help convince other providers to stop antibiotics in patients with pneumonia in whom a non-infectious diagnosis is strongly suspected?
I have looked at both of these studies in some depth. The de Jong et al., study, called SAPS, is perhaps the more impressive of the two, but regarding either or any study on so-called "biomarkers", even the RCT studies only make recommendations or give advice. And, more often than not, the doctors d...
Do you adhere to the standard 5-day minimum treatment duration for community-acquired pneumonia, or have you used shorter courses for certain low-risk patients?
This is a question addressing a shorter duration of antibiotic therapy than the current IDSA guidelines for community-acquired pneumonia (CAP) recommend. It has been the topic of several studies, for example, 3-day treatment (Richard T. Ellison III, MD, reviewing Dinh et al., PMID 33773631; Niederma...
How do you approach management of an ICU patient with brief potentially ictal rhythmic discharges (BIRDs) on EEG?
This is a very challenging question, and the clinical importance of BIRDs, besides being associated with an increased frequency of seizures (Yoo et al., PMID 24535702 ), is unclear. I am a neurointensivist, and in general, I do not escalate therapy for intermittent BIRDs unless we identify concomita...
Under what circumstances would you choose the 1-month 1HP treatment over a 3-4 month regimen for latent TB?
I tend to favor the 1-month daily isoniazid–rifapentine regimen (1HP) in very specific clinical and programmatic contexts, rather than as a default option. Its main advantage is speed i.e. when there is a narrow window to complete latent TB treatment such as prior to imminent immunosuppression (e.g....
How do you manage catheter-associated, upper extremity superficial venous thrombosis?
I manage catheter-associated upper extremity superficial venous thrombosis (SVT) conservatively with arm elevation, warm compresses, NSAIDs, and topical creams containing NSAIDs. Upper extremity SVT is primarily caused by indwelling intravenous catheters, so I do strongly recommend catheter removal ...
Do you maintain a strict platelet threshold of >50k when performing a lumbar puncture, or are there situations in which you feel comfortable with a lower threshold?
Our institution still uses 50k as a best practice guideline, though many of our proceduralists are comfortable performing the procedure with platelets slightly lower than 50k, and will have a risk/benefit discussion with the patient/team about the bleeding risk prior to proceeding; I myself would be...
What pharmacologic and non-pharmacologic strategies have you found helpful in managing brain fog following COVID-19 infection?
In general, a systematic approach should be taken to evaluate COVID-19-related brain fog, which can then guide treatment. Additionally, brain fog following COVID infection can often be multifactorial, and the treatment accordingly often needs to be multi-pronged and comprehensive. The recommendation...
Do you routinely hold anticoagulation (including pharmacologic VTE prophylaxis) for bedside procedures such as paracentesis, thoracentesis, and central venous catheter placement?
We do not hold anticoagulation of any kind for paracentesis. I also do not hold anticoagulation of any kind of thoracentesis, though some places will still ask things like Plavix or DOAC to be held. We do hold ppx and anticoagulation for LP due to the risk of epidural hematoma. I do not hold for the...
How do you use IVC caliber and collapsibility to guide decisions about diuresis?
I use IVC caliber in conjunction with my lung exam to assist with the assessment of right and left atrial pressures respectively. The IVC assessment has many caveats in different patient populations, and evaluation with POCUS can be done in two planes to better understand IVC shape.Caveats - IVC siz...
How do you counsel patients who are concerned that discontinuation of certain chronic medications may actually perpetuate suffering at the end of life?
Great question, and it’s very nuanced. I’ll share how I typically approach this based on my experience. In the end-of-life care setting, when I review a medication list, I go through every single one and ask: “What is the purpose of this medication in this particular case?” For example, anticoagul...
