POTD: Mandated Reporters (LLFTP #7)

 ·   · 

We're back to our regular installments of "Lesson Learned From The Pitt", now covering episode 7 as we slowly catch up to the releases. 

Spoilers, oh boy are there spoilers. Here's a link to a quick reference guide for the TL;DR crowd. 

And a trigger warning for allegations of CSA.

To me, episode 7 is where the Grey's Anatomy-esque drama really starts to kick off. We've been seeing signs of various teakettles slowly reaching their boiling points across the first third of the season, and the first to boil over is — unsurprisingly — the man who's been crushed by a multiple days' worth of critical patients in a single morning, while juggling patient satisfaction concerns, while dealing with increasingly-frequent PTSD flashbacks. When Whitaker eats lunch at a desk, he tells him off for not eating in the lounge (and for spilling a boatload of crumbs on the workstation, get that boy a SLP evaluation!) while also implying that it's too busy for the student to be eating. When Dr. Mohan orders additional labs on a patient he'd medically cleared for psych evaluation (premature closure after not taking an actual history, nice!) he berates her rather than appreciate her ability to tease out highly relevant and plan-changing information in the history, with Dr. Collins being caught in the crossfire for supporting her junior. But Dr. Robby's real explosion is yet to come, so let's turn to someone else who crosses the Rubicon this episode. 

Dr. Mohan isn't the only one who's a bloodhound on tiny details — we've been seeing Dr. Santos investigate the mystery of the hard-to-open benzo vial in the background, and in this episode her vigilantism will continue. Previously, a trauma patient (s/p mechanical fall from ladder) had needed intubation and a chest tube; Dr. Santos had noticed gynecomastia (enlarged breast tissue) which could be a sign of an underlying condition like alcoholism, and decides this needs to be investigated further in the ED before she sees any new patients. On questioning the wife, we find out that she's been doping her husband's coffee with progesterone. Why? Because she suspects her husband of molesting their daughter, and wanted to "kill his libido". 

Dr. Santos appropriately brings this to the attention of Dr. Robby (hey, she does know how to escalate to the right person!), knowing that they are mandated reporters in this state. However, Dr. Robby and social worker Kiara (both heavily overworked by this point) proceed to make one of the biggest fumbles of the show so far — telling her that they cannot make a report without "proof" and that this is all speculation. That they "can't do anything" unless the daughter comes forward. They are right in that they need to report the wife for poisoning her husband, which would at least be a first step (if suboptimal) in getting an authority involved in the situation. 

Detective Santos goes around her attending and tries speaking to the daughter after a clumsy (and failed) attempt at building rapport. The daughter denies everything and is obviously uncomfortable with this conversation. And so our brilliant intern decides to take matters into her own hands, by entering the room of an intubated and vulnerable patient, confronting him, and threatening him ("blink once if you want me to let you die"). Whether Mr. Dunn is an abuser or not (at this point we only have allegations, and in America we believe in "innocent before proven guilty"), for a physician to behave in this manner is beyond the pale. Our ethical duty is to provide unbiased and professional care to everyone regardless of their standing, and certainly not to threaten a patient with prison rape or even murder (imagine being an innocent man or woman and having your doctor come into the room accusing you of heinous crimes, while you're powerless to do anything if they decide to disconnect your ventilator). Taken in context with Dr. Santos's pattern of reckless behavior and disregard for others, I can only hope that the trauma bay is recorded (like ours) and this leads to disciplinary action. 

What should Dr. Santos have done?

She's absolutely right about being a mandated reporter. In both PA and NY law, most professions that come into contact with vulnerable populations (such as children) fall into that category. The threshold to make a report is not "we need proof", it's "reasonable cause to suspect". PA law clearly states that a specific disclosure by a third party to a mandated reporter that an identifiable child is the victim of child abuse meets that standard; that the accuser is the alleged victim's other parent heightens the need to make a report. NY law, which is what matters for us, specifies that a report should be made "when they have reasonable  cause  to  suspect that  a  child  coming  before  them  in  their professional or official capacity is an abused or maltreated child, or when they have reasonable cause to suspect that a child is an abused or maltreated child where the parent, guardian, custodian or other person legally responsible for such child  comes  before them in their professional or official capacity and states from personal knowledge facts, conditions or circumstances which, if correct, would render the child an abused or maltreated child". #Believe when it comes to the threshold for making a report. Let the police do the investigation.

Both PA and NY have hotlines for mandated reporters to make reports. In New York, we can call the State Central Register Mandated Reporter hotline directly at (800) 635-1522. Reports can also be made anonymously at (800) 342-3720. For mandatory reports, a written report must be made and sent within 48 hours of the call. Reports are confidential. One does not need the approval of a supervisor to make reports. One cannot be held liable for good faith reports. One is theoretically shielded from backlash/retributions from making reports. Not reporting when you have reasonable suspicion is a thoughtcrime for which one can be hit with a Class A misdemeanor. PA offers similar protections as NY, and even harsher penalties for failure to report (up to a 2nd degree felony). 

It's hard for someone, especially a transitional year intern, to gainsay the attending. But would you be willing to commit a crime for the attending? We already know Dr. Santos is willing to commit crimes for herself :D

Other little lessons from episode 7:

  • To quote Dr. Collins, "leave your baggage at the door like everyone else". An impaired physician, nurse, paramedic, etc. is a terrible thing for a patient. 

  • Dr. King demonstrated an excellent conversational approach to patients with autism spectrum disorder. She minimized distractions by closing the doors, shutting off alarms, and turning down the lights. She invited the patient to speak about their concerns and verbalized empathic statements. She was patient with her clarifications. She took time to explain the diagnosis at the patient's level of understanding. Note that these are things that can be done with all patients to improve their experience. 

  • During a cardiac arrest code, the team attempts double sequential defibrillation for refractory v-fib. The 1st shock theoretically potentiates the effect of the 2nd. Unfortunately, meta-analyses have found no overall benefit to v-fib termination (or survival), and it is not recommended by the AHA for routine use.   

  • For that same code, the team activates their ECMO team. Extra-Corporeal Membrane Oxygenation is a technology that oxygenates a patient's blood outside the body and then returns it, analogous to hemodialysis. Broadly-speaking, it is indicated for acute cardiac or pulmonary failure that is potentially reversible, has failed conventional treatment, and carries a high risk of death. In-hospital cardiac arrest is an example of a condition that has a decent chance (~30%) of survival with ECMO.

POTD: Platelet Transfusions

 ·   · 

We're going to kick this week off with a PSA requested by the admins and blood bank — a clarification on the kind of platelets we have and how (and when) to order them, especially as part of a massive transfusion protocol.

First, let's start with a quick review. The most common definition of "massive transfusion" is replacement of one blood volume (approximately 10 units, or 5 liters) within a 24-hour period; but more useful to us in the emergency setting are the alternative definitions of transfusion of >4 units of pRBC within 1 hour, or 50% of blood volume within 3 hours, with foreseeable ongoing need. In this setting, the patient is at risk from the lethal triad of hemorrhagic shock — hypothermia, acidosis, and coagulopathy. Healthcare institutions have developed their own "massive transfusion protocols" as streamlined workflows to expedite delivery/administration of blood products and mitigate the lethal triad. 

As we've learned in prior POTDs, in MTPs we transfuse blood products in specific ratios in order to mitigate dilutional coagulopathies — fresh frozen plasma (FFP) provides the fibrinogen, protein C and S, and coagulation factors that are missing in packed RBCs, and platelets are platelets. Sometimes a protocol also calls for cryoprecipitate, which is derived from FFP and contains fibrinogen, factor VIII, factor XIII, and vWF. The "textbook" ratio that you'll hear is a 1:1:1 ratio of pRBCs:FFP:platelets, though some protocols call for a 2:1:1 ratio which has not been found to be inferior. 

Here at Maimonides we use the 1:1:1 approach. However, that doesn't mean that we order 4 units of pRBCs, 4 units of FFP, and 4 units of platelets in SCM. Each "unit" of platelets in the 1:1:1 approach refers to a unit of platelets derived from whole blood donation, which yields >55 billion platelets in ~50 mL. However, as technology has advanced, most platelets are now gathered through apheresis — a procedure that removes platelets from blood and returns the remainder to the donors, yielding >300 billion platelets in ~250-300 mL. Thus, our single unit of platelets here is roughly equivalent to 5-6 old-school units of platelets. 

As you can see on the ED blood bank request form, we order 1 unit of platelets in each round of MTP to go along with 4 units of pRBCs and 4 units of FFP. A similar ratio can be seen in the pediatric weight-based protocol as well. The indications for MTP here are also stated. For adults: massive bleeding, 10 units in short period with uncontrollable blood loss, ruptured aortic aneurysm, abruption placenta, post-partum bleeding. For peds: massive bleeding, anticipated blood loss of 100% TBV within 24 hours, ongoing hemorrhage of >10% TBV/minute, replacement of >50% TBV within 3 hours. 

When you place the order for platelets through the "ED Blood Products Order Set", you can also see that 1 unit (at 200 mL/hr) is the default selection. Leave this at 1 unit for the vast majority of cases including MTP. If you order 4 units here, it'll look like you want to give the patient 20+ standard units of platelets. The blood bank won't actually give you extra units of platelets without question, but it creates confusion in the system.

Outside of massive hemorrhage, there are several indications for administering a platelet transfusion. The list of approved indications is found in the drop-down menu when ordering platelets through the order set, and include: 

  • active bleed on antiplatelet medication with documented platelet dysfunction

  • platelet count < 20K prior to central line placement

  • platelet count < 20K prior to bone marrow biopsy/aspiration

  • platelet count < 20K prior to diagnostic lumbar puncture

  • platelet count < 10K with or without active bleeding

  • platelet count < 50K with active bleeding or prior to major surgery

  • platelet count < 100K prior to neurosurgery or ophthalmic surgery

A single unit of apheresis platelets is expected to increase the platelet count by 30K-60K (per µl) in a 70 kg patient. For most of the above indications, transfusing 1 unit is generally sufficient; if the deficit is wide, a 2nd unit can be ordered after rechecking a platelet count. 

There are times when the platelet count is low and platelet transfusion is not indicated. In immune thrombocytopenic purpura, treatment is IVIG + steroids with platelets only recommended prior to procedures/surgery or if there is life-threatening bleeding. Meanwhile, platelet transfusion is contraindicated in thrombotic thrombocytopenic purpura and heparin-induced thrombocytopenia due to increased risk of arterial thrombosis and death, with the exception of cases of life-threatening bleeding.

POTD: Displaced Clavicles (LLFTP #6)

It's Friday yet again, and here's another pearl from The Pitt

Spoilers for the betting pool!


Several episodes ago, someone stole an ambulance that had been parked outside with the keys in the ignition (while there was good intent in "allowing someone to move it if needed", it was a violation of their EMS department policy). Since then, there's been a betting pool around who the perpetrator(s) are, how far the thieves would get before being stopped, and what condition the ambulance would be in. In episode 6, we get to see the results of the chase: two frat bros (sorry, one bro and one pledge) stole the ambo, decided they would take a joyride and have a merry police chase (the kind of classic mockery of Darwin that is so endemic to that demographic), and then crashed the ambulance into a tree. Tragically, that kind of impact vs a large stationary object means that this critical healthcare resource will be out of circulation. The frat bros are also injured, and are brought to the Pitt for care. 

Of the two rapscallions, the pledge is in far worse condition than his senior (whose product-laden frosted tips look totally unruffled). Miles Hernandez, 18 years old, unrestrained (because of course), arrives to the ED with signs of injury to the right chest and left leg, shortness of breath with an O2 sat of 91% on ?L supplemental O2 via nasal cannula, HR 120s, BP 100s/70s. Miles exhibits easily-audible wheezing when he tries to speak, with diffuse high-pitched breath sounds on lung auscultation. Dr. Robby quickly notices that the head of Miles's right clavicle is centrally depressed, raising concern for a posterior sternoclavicular dislocation, which could compress the trachea and explain his dyspnea. The dislocation is reduced with local anesthesia and a towel clamp, with immediate improvement in Miles's vocal quality and respiratory symptoms. 

A quick anatomy review — the clavicle (or "collarbone") is the bone that connects the scapula to the sternum to form the shoulder girdle. Its name comes from the Latin diminutive clavicula ("little key"), so called due to its shape and manner of articulation. The two joints of the clavicle are the sternoclavicular joint and the acromioclavicular joint, with dislocations of the latter being far more common than the former. AC dislocations classically occur in younger males playing contact sports, but can occur due to any trauma to the shoulder/extremity. Depending on the degree of injury, a high-riding/elevated clavicle might be visible/palpable on exam. The Rockwood classification of AC injuries is based primarily on the involvement of the acromioclavicular and coracoclavicular ligament complexes, with the combination of exam and radiographic findings being sufficient for determination. Type 1 and 2 injuries are usually managed nonoperatively w/ sling and orthopedics follow-up, Type 3 and up require a consult for OR reduction/stabilization (with some stable type 3 variants being eligible for nonoperative management). Complications of AC dislocation typically comprise pain and loss of function. 

Sternoclavicular (SC) dislocations also occur with trauma (or hypermobility disorders) and are considered high-energy injuries. The shape of the articular surface is inherently unstable, relying on ligamentous complexes to aid in stability. Anterior dislocation results from lateral compression on the shoulder girdle resulting in rupture of the anterior joint capsule; this causes pain and a visible/palpable bump over the SC joint. The posterior joint capsule is stronger and less prone to rupture, but a posterior dislocation still may result from direct force over the anteromedial clavicle or from indirect force to the posterolateral shoulder; symptoms of compression to the airway, nerves, vessels, or esophagus may occur, and may require urgent reduction. Anterior SC dislocation can be reduced at beside with direct pressure while the ipsilateral arm is abducted 90 degrees, but the rate of recurrence in absence of ligament reconstruction is high; and with the low mechanical impact of this type of dislocation, reduction may not be needed if pain is controlled. Posterior dislocations can be reduced with the towel clip method demonstrate in The Pitt, or with the application of extension force to the abducted tractioned shoulder. 

It is also possible to have a "bipolar clavicular dislocation" where both the SC and AC joints are disrupted. In the less than 50 known cases, all involved high-energy blunt trauma and all but 1 had anterior SC dislocation. 

Other little lessons from episode 6:

  • Remember the ABCD's of ED efficiency — Always Be Constantly Dispo'ing! Getting patients out of the ED as soon as medically stable is the best tthat we can do as ED staff to address ED overcrowding. 

  • Dr. Shamsi (surgery bigwig) demonstrates the psoas sign in appendicitis by having the patient flex his hip against resistance. The more orthodox method described by Sir Cope in 1921 involves passive extension of the patient's right hip with them lying on their left side. The test is fairly specific for appendicitis, but not sensitive (i.e. positive test rules in, but negative test does not rule out). See this article for more information.

  • If holding sharps: keep a tight grip and move slowly and deliberately. 

  • Sometimes, ignorance is bliss. When giving bad news (like dead tapeworm eggs in someone's brain), ease them into it with SPIKES.

  • When Mel was FaceTiming her sister in the ambulance access road, I was so worried that she would get hit by an ambulance. When walking to and from the hospital, please be mindful that the laws of physics trump any laws of man. The intersection of 48th St. × 10th Ave. is especially bad with drivers running the stop signs. 

Have an amazing weekend!
