On Thursday morning at the VA, we discussed the management of acute COPD exacerbation. The patient was a 65 year-old man with GOLD class D COPD admitted several hours prior with increased productive cough and wheezing for the past 5 days. He developed worsening shortness of breath with evidence of diffuse wheezing and accessory muscle use on physical exam despite treatment with antibiotics, bronchodilators, and corticosteroids. His labs were consistent with an acute on chronic respiratory acidosis and the decision was made to initiate bi-level non-invasive ventilation. With the help of our expert pulmonologist, Dr. Mark Fuster, we discussed the variables to consider when initiating BiPAP as well as how to interpret the machine interface and waveforms.
We then discussed variable that indicate that hypercarbic respiratory failure is responding to NIV, and the need to remain at bedside to assess the patient in real time. An hour later, the patient continued to be tachypneic with evidence of worsening acidosis. We considered variables to troubleshoot, including assessment of tidal volumes, adequacy of EPAP, and evaluation of patient-ventilator dyssynchrony (including the need to watch out for dynamic hyperinflation!) The patient in this case had a large amount of leak around his face mask (due to a full beard) and improved when switched to a nasal interface and an increase in his driving pressure.
Special thanks to Dr. Fuster and all our participating residents!
The COVID-19 Vaccine is now available at the SD VA for our inpatients! You can order it by going to: Inpatient Meds and then clicking the Immunization/Skin Test menu.
One caveat to keep in mind: for patients going to a SNF, please discuss vaccination with the Social Worker. Vaccination can negatively impact disposition options, as some SNFs require other vaccines (pneumovax, influenza) and the CDC still recommends a minimum 14-day interval before or after administration of any other vaccine.
Reach out to Alex Cypro (firstname.lastname@example.org) with any questions or concerns. Go and vaccinate your patients today!
Tuesday morning report at the VA was all about diuretics. We presented a case of a 73-year-old man with history of CHF, CKD and T2DM who presented with progressive dyspnea, bilateral lower extremity swelling, orthopnea, and abdominal distension. Physical exam showed evidence of volume overload with 3+ pitting edema, elevated JVD, and bibasilar pulmonary crackles. We considered various common triggers of heart failure exacerbation before diving into a discussion of diuretics.
Key points that we highlighted:
Decongestion with resolution of symptoms and edema is achieved through “diuresis” = loss of sodium (natriuresis) + loss of water (diuresis). That is why sodium-limited diet is crucial in treatment of fluid overload.
Loop diuretics function as “threshold” drugs that need to achieve a sufficient concentration in order to work. The natriuretic threshold is higher in patients with acute CHF than in healthy persons. That is why hospitalized patients require loop diuretic doses that are higher than stable outpatient doses.
Loop diuretics exhibit a “ceiling” effect and doses above the ceiling will not increase the amount of natriuresis. Acute CHF shifts the relation between plasma diuretic concentration and sodium excretion to the right and reduces the “ceiling.”
Patients with chronic diuretic use develop post-diuretic sodium retention and decreased efficacy with each subsequent loop diuretic dose. That is why loop diuretics are dosed multiple times daily and why patients need a net negative sodium balance each day.
Chronic loop diuretic use leads to distal tubular hypertrophy and once maximum loop diuretic effect is reached, auxiliary diuretics are sometimes used (thiazide, aldosterone antagonists, carbonic anhydrase inhibitors). We discussed specific situations you may consider using these agents.
Ethacrynic acid is the loop diuretic of choice in patients with sulfa allergy.

This morning one of our stellar resident, Dr. Mandy Mohindra, presented a patient who developed a fever six days into a hospitalization for volume overload. The patient reported a history of worsening chills with rigors, loss of appetite, nausea and vomiting, and fatigue. He had an infiltrated IV with right upper extremity swelling on exam. The patient’s history was significant for liver transplantation three years before (on tacrolimus), diabetes, and severe aortic stenosis. We discussed the decision to start empiric antibiotics, and the workup eventually revealed MRSA bacteremia. The most likely source was the infiltrated peripheral IV.
We were lucky to have our Infectious Disease expert extraordinaire, Dr. Annie Cowell, to lead us through the management of Staph Aureus bacteremia as we discussed the need to evaluate for potential sites of metastatic MRSA infection. A wrinkle in our patient’s case was that his blood cultures were persistently positive for MRSA. This prompted a change of antibiotics from vancomycin to ceftaroline and daptomycin and a search for endocarditis. A transthoracic echocardiogram did not reveal valvular vegetations, but a subsequent ECG revealed a new 1st degree heart block. The patient underwent a transesophageal echocardiogram which ultimately demonstrated a paravalvular abscess for which cardiothoracic surgery was consulted. Thank you to all of our resident teams for participating in the discussion. And thank you to Dr. Cowell for adding context to our patient’s clinical course!
Who: Residents can take this course prior to obtaining their own DEA – your completion will be recorded for use later.
What: AAAP Buprenorphine Half and Half Course (½ online independently and ½ “in person” via Zoom)
Where: YOUR OWN HOME via Zoom! You MUST RSVP in advance, attendance will be taken
When: September 17th, 2020; 8 am -12:30 pm (you must attend the entire time for the waiver)
Why: To be qualified to get a DEA waiver to prescribe buprenorphine products (one common brand name is Suboxone) AND to feel confident managing this growing patient population
This course is designed to equip prescribers with the information necessary to understand and prescribe buprenorphine in a safe and effective manner. It also meets the 8-hour requirement (½ in person; ½ on line) for MD’s and DO’s to apply for the DEA waiver to prescribe buprenorphine.
This training is for ½ of the 8-hour requirement. The remaining 4 hours must be done online, and you must pass a self-study exam to apply for the waiver. Contact Carla Marienfeld (email@example.com) if you are interested in attending.
Today our amazing future chief Dr. Averie Tigges discussed a case of a young man with SCI admitted for UTI, but used the case to discuss the greater concept of malnutrition. Averie walked us through some of the prior rationale for using pre-albumin and then discussed why it is actually not a useful bio-marker for malnutrition (its a negative acute phase reactant!) . She then discussed the different clinical scores available to assess malnutrition and highlighted the choosing wisely recommendation to utilize one of these scores over pre-albumin for assessment of malnutrition.
Today our chief of Pulmonary Critical Care division, Dr. Jess Mandel, gave us an update on our surge planning during an All-Physician Town Hall meeting for UC San Diego Health System.
UC San Diego Health System CEO, Patty Maysent, first gave an update on the resources available, testing capabilities, and provider resources. Dr. Vaishal Tolia, director of the EM department, then talked about the ED efforts for planning specifically how they improved the flow of care, incorporated telehealth, secured adequate equipment, and expanded staffing. Dr. Dan Bouland, head of Hospital Medicine, then went over the tiered plan of service expansion to plan for increased census numbers during the surge.
Dr. Jess Mandel, then went over the plan for the critical care unit. He emphasized the need to have a team based approach and went over the 9 phase plan in regards to space expansion and materials required during the surge. He also went over the number of ventilators available, and the staff expansion plan. Next, he gave us some statistics on how San Diego’s number compare to other cities and how we prepared we look in the context of the projected models.
They ended with answering all questions from the multidisciplinary audience.
Thank you all for this overview of our surge planning.
