Neuro ICU

 

The Neurosciences Intensive Care Unit (NEURO ICU) mission is to provide state of the art life-saving and intensive supportive care to critically ill neurosurgical and neurological patients. The patient population includes patients admitted to the Neurosurgery or Neurology services. This will include but is not limited to pre- or post-operative neurosurgery patients; patients with large hemispheric infarct (LHI), subarachnoid hemorrhage (SAH), intracerebral hemorrhage (ICH), and patients with other acute neurological impairment, as well as any patient who is deemed critically ill and requires emergent intensive care unit care.

The goal of the NEURO ICU rotation is to allow fellows, residents and medical students an opportunity to learn and apply critical care medicine principles in the above patient population.  Unique aspects of this rotation are as follows:         

  • To learn management principles in intracranial hypertension, SAH/ICH/LHI status epilepticus and neuro prognostication.

  • To be exposed to neurological diseases that require intensive care treatment such as primary malignant tumors, acute neuromuscular diseases and seizure disorders

  • To learn how to identify and treat infections in neurologically ill patients;

  • To learn to manage common critical care problems such as, but not limited to, acute coronary syndrome, shock, sepsis, arrhythmias, ARDS, and AKI.

  • To learn to care for patients with other organ support devices such as ventilator management and CRRT.

  • To learn how to work in a unit with a multidisciplinary provider model including critical care Nurse Practitioners (NP), residents from neurology, neurosurgery, and ENT, and critical care fellows from Anesthesiology, Neurology, Emergency Medicine and Internal Medicine.

The NCCU is divided into two units with 12 beds on the West side and 10 beds on the East side. Residents typically rotate on the West side and are assigned between 6-7 beds. The Residents are responsible for taking care of any patients in those rooms as well as any admissions or transfers to and from those rooms.

‍The NeuroICU is considered a closed unit meaning all orders are placed by the ICU team. However, many patients are co-managed with either stroke neurology or neurosurgery and are admitted under a neurosurgery or stroke neurology attending. General neurology patients are admitted under a neuro ICU attending and not typically followed by the general neurology (CNS) service until ready for transfer out of the ICU.

It is expected that you complete this checklist of activities during your time on the NCCU. Please discuss this with either the fellow or attending on service.

Helpful info

  • Please reach out to the outgoing resident on the Friday prior to your rotation in order to get sign out and find out which section of the ICU you will be taking over on Monday.

  • Please be ready to receive sign-out at 6:30am from the nighttime provider. Arrive earlier on the first day in order to get oriented to your new patients and be prepared for rounds by 8 AM.

  • Many residents utilize the “MD sign-out w/o notes” page on Epic for pre-rounding and presenting on rounds.

  • Use the computer-on-wheels to display imaging and place orders when not presenting on rounds.

  • The Neuro ICU has the following TigerConnect Roles that can be used to facilitate communication:

    • UMMC Neurocritical Care Triage Attending

    • UMMC Neurocritical Care Fellow

  • For any emergent concern, please call the Attending via the direct line at 8-4552 (24 hours/ 7 days), rather than texting via TigerConnect.
                   

RESIDENT RESPONSIBILITIES   

The NEURO ICU resident(s) is responsible for obtaining the history and physical examination, reviewing all laboratories, imaging findings and placing orders for every patient they admit to the Unit. The resident, under the supervision of the NCC attending, is the primary practitioner responsible for the care of a certain number (usually not more than 6) patients during the daytime. They are responsible for all 12 patients in the Unit during their Friday overnight.  The resident is responsible for pre-rounding each morning and presenting the patients assigned to him/her during rounds in a structured format (see below).  It is the expectation that the resident will formulate a patient care plan for each patient and follow that patient.  The resident is also responsible for keeping the attending informed as to admissions, transfers and patient status. Residents will present their patients at morning rounds and maintain daily sign out notes on their patients that will serve as the basis for transfer summaries for when patients leave the ICU.  It is expected that the resident will be ready for attending rounds at 0800, participate in Attending sign-out rounds at 1630, and give report to the night team at 1830 on the unit.  Once a week (Friday), the resident will be on a 24 hour shift, from Friday 0630 - Saturday 0700. An NP will be covering the other side of the NCCU and will be available for support and assistance. Daily provider notes written under “Notes→incomplete” will serve as the basis for transfer and discharge summaries when patients leave the ICU.   

PGY-1 OR 2 ROTATION

Prior to beginning the rotation, residents should contact Dr. Badjatia’s admin, Lorine Andersen (landersen@som.umaryland.edu), to schedule an introductory meeting. The PGY-1 or 2 [“Junior”] resident rotates on the NeuroCritical Care Unit (NCCU) at University of Maryland Medical Center in one 2-week block as a PGY-1 or one 4-week block as a PGY-2. The NCCU is a 22-bed start-of-the-art combined neurology/neurological surgery intensive care unit that receives patients with severe and acute neurological emergencies who require advanced monitoring, mechanical ventilation, cardiovascular support, invasive procedures, and neurosurgical interventions. The junior resident participates as a member of the NCCU team, and has the role of evaluating and admitting patients, gathering clinical information from patients, families, and other medical sources, accumulating laboratory data, presenting a synthesis of the case to the attending neurointensivist, contributing to management decisions, performing procedures, providing follow-up assessments and evaluation, maintaining ongoing electronic record of each patient’s clinical course, and preparing summaries for patients discharged from the NCCU.

DAILY ROUTINE OF THE NEURO ICU   

Sign-out Rounds

The incoming day practitioner will obtain a sign-out or report from the outgoing night practitioner regarding the status of the current patients in the NEURO ICU.  The active bed requests and the patients that could possibly transfer out of the NEURO ICU should be reviewed.  These activities should be done in a timely fashion in order to be ready for 0800 Attending Rounds.   All sign in/out activities will follow a structured format that adheres to the UMMC Graduate Medical Education guidelines.

Morning Rounds

At 0600 each morning the overnight practitioner (not daytime practitioner) will attend the morning work rounds with the surgical team. Bedside rounds with the NCC attending will begin at approximately 08:00 daily. Rounds will be attended by the NEURO ICU attending, fellow, NPs, residents, medical students, nurses and ancillary staff.  It is understood that fellows, NPs, residents, and medical students will have seen and evaluated all of their assigned patients in the NEURO ICU prior to rounds.  Nursing input is vital to patient care.  It is the responsibility of the ICU team to notify the nurse at the time that the ICU team begins rounding on their patient.  During rounds, one resident / NP presents with appropriate images and labs available for review, while another inputs orders. This maintains a constant, efficient work flow, allowing for more time for teaching and for most (ideally all) orders to be placed during rounds. Interruptions from rounds should be limited to emergencies only (i.e. non-emergent phone calls should be returned later).

Multidisciplinary Rounds

At 1100 each morning the charge nurses from the ICU, step down unit and floor, as well as case managers from neurology and neurosurgery will meet for 30 minutes to discuss pending transfers and begin discharge planning for patients from the intensive care unit.  The purpose of this meeting is to improve patient throughput and maximize resources between patient care settings. It is the expectation the fellows and / or ICU triage attending will attend these daily am rounds. Residents may be asked to attend if the NCCU fellow is post call on Thursdays.

NIGHT CALL

This will occur once a week with the Neurology resident on Fridays.  Night call begins 630 PM and ends by 0700 AM. The on call provider will “run the list” with Attending on call for the Neuro ICU between 9-11 PM.  At 630 AM daytime will receive sign out from on call provider. Additionally, on call provider is expected to call the on call attending with any new admissions or significant events.  As with new patients during daytime, the on call provider is expected to enter an admission note.  For any events on existing patients, the on call provider is expected to update sign out note in Epic.

Procedures

Procedures will be performed by the residents or medical students under the supervision of the fellow/attending.  Endotracheal intubations will be performed primarily by the critical care attending. Critical care fellows may perform intubation under appropriate supervision.   

Notes/Orders

Medication Reconciliation shall be done on admission with history detailed from patient, family or pharmacy.

All restraint orders will be documented within 15 minutes of application and will be reassessed and re-ordered every 24 hours.

A running transfer summary is to be written on all patients daily by the responsible NP, fellow, resident or fourth-year medical student.  All notes written by a resident and fellow should be co-signed by an Attending physician in a manner consistent with compliance guidelines. A medical student’s note is not considered the daily patient note; a higher level practitioner should write his/her own note.

All orders should be entered into the computer. Those orders discussed on rounds should be entered during rounds.  Except for urgent orders, all orders by primary or consulting services must be reviewed by a NEURO ICU physician.

A template for the daily progress note is accessible by typing: .NCCUTRANSFER

Transfer, Discharge and Interim Summaries

ICU discharge summaries will be written by the ICU provider primarily responsible (NP/resident/Fellow) for the patients who expire or are discharged from the NEURO ICU to an outlying facilityDischarge. A “death note” and death certificate also need to be completed for patients who expire.

  • Neurology:

    • Transfer summaries are written for all neurology patients moving to another floor in-house phone call.

    • Discharge summaries and the depart process will be done by the ICU providers for all neurology patients regardless of length of stay.

  • Neurosurgery:

    • Transfer summaries are written for neurosurgery patients with a length of stay > 72 hours and will be entered into Epic. <72 hours Neurosurgery will write discharge summary or transfer summary.

    • Discharge plans and medications are entered by the Neurosurgery team only as they will follow the patient after discharge from the hospital.  The discharge order is placed by the ICU team.  A discharge summary should be written if the patient is here >72 hours.

Attending Sign-Out Rounds

Sign-out rounds with the Attending will be performed beginning at 1630 daily.  The NP, resident, fellow and attending will participate in these brief 30 minute rounds that are focused on ensuring AM goals are being met and developing specific overnight goals of care.     

COMMUNICATION

Communication among the NEURO ICU staff and primary service / consulting services is absolutely essential to the smooth function of the NEURO ICU.  The quality of patient care depends on the lines of communication being open and used frequently.

Patients in the NEURO ICU are cared for by the NEURO ICU team in collaboration with each patient’s primary and consulting services.  Recommendations for care as well as the patient’s changing status should be made known to the primary service as soon as possible. Consulting service recommendations must be approved by the critical care attending.    

Anticipated discharge of a patient from the NEURO ICU must be communicated in a timely fashion.  Emergent admissions or discharges will be handled as judiciously as possible.  Communication prevents confusion and misunderstandings and is a hallmark of quality patient care.   

Any conflicts in the management of patients between the primary service and the critical care team that cannot be resolved in a timely fashion should be brought to the attention of the Medical Director immediately (24/7/365).

Given there may be a delay of up to several days that may occur between time of down grade and time of obtaining a bed, at the time the patient receives a bed in the IMC/floor, page/contact Neurology resident to notify them of the transfer and to communicate any new critical information.  The NCC service will continue to take primary responsibility for all patients during the time that the patient is downgraded but still in the ICU.           

GUIDELINES FOR NEURO-ICU PRESENTATIONS

Because ICU patients can be complicated, presentations on morning rounds are most effective when they are structured and well-organized.  The role of the presenting resident is to convey a coherent picture of what has been "going on" with the patient to the rest of the team.  This serves as a take off point for examination of the patient, review of imaging studies, and discussion.  The end-point of each discussion is to formulate a plan for the day. We expect the resident/NP (not Fellow or Attending) to initiate the discussion of a plan by systems.   A systems format for organizing morning presentations follows:   

  1. PROBLEM LIST: Present a summary of patient and pertinent issues.  eg “ 46 yo SAH HH4F3 PBD 5 POD 3 who has aspiration PNA day 5 of atb and thrombocytopenia due to HIT.”  For new admissions this is replaced by a complete CC, HPI, PMH, Meds, All, SH, FH, ROS).

  2. EVENTS OF PRECEDING 24 HOURS:  (This should include spontaneous breathing trial performance, interventions, diagnostic test results, deterioration, etc). TO BE PRESENTED BY RN

  3. VITAL SIGNS:  HR, BP, RR, Temp, ICP, CPP, PBO2, Microdialysis, I+O's including EVD output. 

  4. DRIPS AND INFUSIONS:  Fluids, vasoactive and sedative meds (by dose not cc/hr), feeds

  5. LABS:  ABG (with vent settings), BMP, CBC, AED levels, others.  No need to read off all labs – provide pertinent highlights and interpretation

  6. BEDSIDE EXAM: Resident/NP provides summary of exam findings noted during pre rounding. The entire team examines the patient together (this may occur here or at end of systems plan).

  7. PLAN BY SYSTEMS (always in this order)

    1. NEUROLOGICAL (what do you think is going on with the patient?  How do you explain the findings?  Are further diagnostic studies are needed?  What are the therapeutic goals for the day? Do we need to adjust any on going therapies? Sedation / analgesia adequate? What needs to be communicated to Neurosurgery/Neurology?)

    2. CARDIOVASCULAR (essential components: rate/rhythm, ischemia, pump, pressure: is cardiac performance optimized for achieving neuro goals? What is the goal BP (MAP)?  hemodynamic values [CVP, CO, CI,SVI, SVRI], ECHO results], ECG & arrhythmias).

    3. PULMONARY (current ventilator settings, performance during weaning over past 24 hrs, CXR, ABGs, secretions, vital capacity,extubate/trach?).

    4. RENAL / FLUIDS, ELECTROYTES, UROLOGIC status  (kidney failure, do meds need renal dosing adjustments, lytes repleted?  Is the patient euvolemic? What are the total fluids the patient is receiving hourly? What are our sodium and/or fluid balance goals?)

    5. HEMATOLOGIC (Hct & platelets, coags, are there transfusion triggers for hb, plt?)

    6. INFECTIOUS DISEASE (Is there any signs of acute infection?  Are cultures being followed up on?  Are antibiotics appropriately dosed/duration?  Are all lines/tubes necessary?  Need for ongoing Foley catheter use must be clearly identified).

    7. GASTROINTESTINAL/NUTRITION (Any signs of ileus, hepatic insuff, or GI bleeling, last BM, is the patient receiving adequate nutritional support?)

    8. ENDOCRINE  (is the serum glucose level well controlled, do we need to adjust; any signs of adrenal insufficiency, s/p pituitary tumor DI watch)

    9. SOCIAL SITUATION/FAMILY STATUS: to be presented by RN.

    10. FAST HUGS BID/CHECKLIST: to be presented by RN.
