Weekly Review #21

Brian Erikson hosted a couple of great guests on erNURSEpro. He discussed ED process improvement with Deb Delaney, and Delirium with Christina Shenvi.

Deb Delaney had some insight on improving ED through-put and made some specific suggestions about internal queues, flow facilitation, use of mid level providers, streamlined ancillary services, room utilization, huddle & hand-off processes, and communication. I've seen several departments use internal queuing, or intra-departmental waiting areas, to create a "fast-track" area and increase throughput of less acutely ill patients. The "flow facilitator" role is often performed by a charge nurse, in small departments this may work well, but in large centers, or during times of peak traffic it does not. Dedicating one person to this role, even if only during peak volume can help clear bottle necks, ensure patients are moving through the system, and ensure that the charge nurse isn't being removed from performing their function, I particularly like the push-pull model of moving patients, as well as bed-side handoffs and impromptu huddles. Delaney offers a few other suggestions, and likely has something that could be implemented at your department, a good review for any nurses working in a charge, or managerial role.

Brian also hosted a talk with Christina Shenvi, a physician and fellow in geriatric emergency medicine. Christina discusses a three step approach to patients with delirium: immediate stabilization and correction of rapidly reversible causes (hypoxia, hypovolemia, AMI), establishing a baseline for the patient (call family, support workers, or care home staff), and the process of ruling out possible causes of delirium using the DELIRIUM mnemonic (covered in weekly review #11). She then discussed possible causes, risk factors, and considerations for interacting with these patients. There are some great pearls on pain assessment, preventing delirium, and steps that can be taken to make an emergency department more friendly to geriatric patients. This is a great podcast, Brian includes some relevant links in the show notes, the discussion is straightforward and informative, and the content is applicable to almost all sub-specialties of nursing; if you're going to listen to only one podcast this week, make this the one!

There was a lot of FOAMed coverage this month on the new 2015 CPR/ECC guidelines. HEFTEMCAST, RebelEM, and BIJC, have all provided great summaries of the updates; but from a readability perspective I would like to highlight the review by Justin Morgenstern on First10EM. His post starts with a review of the evidence informing the changes, then discusses the key recommendations and changes by topic, starting with: CPR, medications, capnography, technology, post resuscitation care, and finally by special patient populations: pregnant, hypothermic, trauma, pediatric and neonate patients. The team at BoringEM also deserve a huge acknowledgement for their amazing infographic series which can be downloaded here, a fantastic review for any nurse that participates in cardiovascular resuscitation.

The Journal of Trauma and Acute Care Surgery published an analysis by Afshar et al., that examined the association of blood alcohol content with in hospital death, injury severity, and mechanism of injury. This is a retrospective examination of patients treated at an American shock trauma center between January 2002 and October 2011. The study assigned patients into 4 categories based on blood alcohol content (BAC): undetectable (<1mg/dL), moderate (1-100mg/dL), high (101-230mg/dL), or very high (>230mg/dL), then examined for severe injury (ISS >16), dichotomous injury pattern (blunt or penetrating), hypotension (MAP < 66mmHg), shock index (SBP/HR - greater/less than 1), and death.

There were 46,222 patient records examined, 44,502 (96%) had blood alcohol content (BAC) assessed, 12,535 (28.2%) were exposed to alcohol with the a median BAC of 167mg/dL (high). Baseline characteristics showed an increase in male representation with increasing BAC quartile (66, 77.5, 79.8, 83.1%). Patients with moderate BAC were more likely to have penetrating injury patterns (typically gunshot wounds), severe injury, hypotension, pulseless arrival, and in-hospital mortality compared to other groups. The very high BAC had the greatest proportion of blunt trauma, falls and fights, the lowest proportion of vehicle collisions, and the lowest odds for in-hospital mortality.

When I first read this research I was a little confused as to what it added to the overall knowledge of alcohol and trauma, other than to say that mechanism varied across intoxication levels. However when this research, on injury mechanisms by BAC quartile, is used in addition to previous research, on alcohol and mortality, we begin to understand why some of the noted effects are occurring. This may be interesting research for nurses working in trauma who are particularly keen on the epidemiology of trauma, but from a straightforward nursing perspective it has little to add to the general approach toward trauma patients.

I recently moved from a small rural ER to a large metro trauma center. On one of my first orientation shifts a patient in DKA was transferred to our department from a rural site. Some of the nurses made disparaging comments about the choice of SC insulin over IV insulin infusion, which started an interesting dialogue. Although I've typically seen these patients treated with IV insulin infusions I do know that the evidence, as well as CDA guidelines, acknowledge that either will produce similar outcomes. I've seen some support for the practice in EPMonthly, which acknowledged similar efficacy between the two, but a new review by EMPharmD offers not only a succinct review of the existing literature, but also a fresh perspective on titrating doses from rapid to a long acting insulin, an approach that if supported by evidence could significantly lower the amount of time and resources required to treat patients with DKA. A great read for nurses working ER/ICU or medicine, and one of my newly discovered favorite sources for FOAMed content.

On InjectableOrange Jesse Spurr hosted a post by fellow Canadian RN Jennifer Jackson on why nurses need to be politically active: to advocate for patients, to advance the nursing profession, and to effect change on our work environment - very timely given our recent federal election. He also posted some links and information for those lucky enough to attend the 2015 SMACC conference in Dublin.

I've reviewed a post by Ian on pre-filled syringes before and strongly feel that they are an effective way to prevent medication errors. One drug in particular where this is of concern is Epi. The differences in concentration between cardiac and anaphylaxis doses is 10 fold. Taft Micks offers a review on the differences between the two on  BoringEM, discussing the risks, and deciphering the labels of the two different doses.

EMin5 reviewed the different presentation, treatment and complications associated with parasitic skin infections. Anna Pickens reviewed the differences between scabies, lice (head, pubic, or body) and bedbugs. This five minute video offers up great photos, neatly summarizes the treatments, and includes a fantastic table that summarizes the video. An excellent review for emergency, correctional, camp, public health, or school nurses.
