Documentation (2024)

by Muneer Abdulla Al Marzooqi

Introduction

Whether rotating in the Emergency Department or elsewhere, one of the critical skills to learn is writing a complete and legible patient record. Documentation in the emergency department is usually challenging, and it may be difficult to adequately capture and note things promptly, especially when dealing with high acuity or critical case scenarios. Even as a medical student or intern, your medical record is essential. It reflects your general approach, thought process, care provided to patients, and potentially identifying gaps in your knowledge and training. Attending physicians, clerkship directors, and faculty usually emphasize and pay attention to how notes are written and may use them for summative or formative assessments and feedback. These documents are also crucial for communication between the emergency department and respective physicians, specialties, and other stakeholders. Appropriate medical documentation improves the quality of communication within an emergency department and aids the quality assurance process.

“It is said that if something is not written in the chart, it never happened.”

A well-organized and legible chart gives auditors and reviewers a clear picture of the physician’s thought processes and actions. It provides a real-time snapshot of a patient’s general condition at any given encounter. There is always room to learn about and improve medical documentation in the emergency department; therefore, this section will review the critical elements used in ED documentation [1,2].

Emergency Medicine Note

Before writing your note, nursing triage notes and vital signs, if available, need to be reviewed. If apparent discrepancies are seen, they need to be verified with the nurse and patient, as they may be errors. In addition, any abnormal vitals in triage must be acknowledged and written in the notes. Like any other medical record, the ED document comprises history, physical examination findings, differential diagnoses, ordered investigations, laboratory and imaging results, assessment, and plan. Each component will be discussed separately, and suitable examples will be provided accordingly [2-4].

History

When writing a patient’s history, one must be clear and thorough yet concise, avoiding lengthy and complex phrases. Ideally, the history should flow in a logical and chronological sequence. Unnecessary details are better avoided, as they serve as distractors and may confuse other readers. Recording the date and time the patient was seen is crucial, especially in critically ill patients. It will help create a timeline for when time-sensitive interventions or medications were administered [3,4].

The components of history

Chief Complaint

This usually includes the presenting complaint, ideally in the patient’s own words, with the duration (e.g., abdominal pain for two days).

History of Present Illness

Generally, there are two formats for writing the history of present illness (HPI): narrative and bullet points [5,6]. Both are acceptable as long as history is written comprehensively, concisely, and coherently. It is valuable to add pertinent negatives and positives when writing the HPI. It would show the physician’s thought process and lead the person reading the chart toward what differential diagnoses to consider and what to rule out depending on what the patient is presenting with. Specific mnemonics may aid in writing a systematic HPI (e.g., OLD CARS or OPQRST).

Example 1:

A 45-year-old man with a history of Coronary Artery Disease and Hypertension presented to the ED with chest pain that started three hours prior. The pain was gradual onset while sitting on his chair, localized in the center of the chest, and lasted for 20 min. It was described as “a heavy boulder on my chest.” It started when he quarreled with his daughter and was relieved with sublingual nitroglycerin. It was associated with nausea and sweating but not vomiting. It was localized and did not radiate into the shoulders or arms. He claimed the pain was moderately intense at 4/10 on the scale. The patient denied shortness of breath, palpitations, dizziness, or abdominal pain.

Example 2:

A 26-year-old male, previously healthy, presents with a sore throat for one week. It is associated with subjective fever and fatigue. It is aggravated whenever he drinks or eats, but he denies any difficulty swallowing or drooling. Also denies any chills, runny nose, cough, night sweats, or shortness of breath. No recent travel history was reported. Has several sick contacts at home with similar symptoms

Review of Systems

Other organ systems and symptoms not mentioned in the HPI must be reviewed to ensure that the patient has no other complaints or organ system involvement. If a review or system (ROS) cannot be obtained because of the patient’s underlying condition (i.e., unconscious, critically ill, or having dementia), this should be noted in the chart. Generally, patients are asked questions from head to toe (e.g., “Do you have a fever, chills, headache, sore throat, chest pain, abdominal pain, urinary symptoms, etc.”). Document all positive ROS symptoms and state the remaining symptoms as otherwise normal [7]. 

Past Medical/Surgical History, Medications, and Allergies

List any known illnesses that the patient might have had in the past. Include any surgical procedures he had. State what medications he is actively on and whether he has any drug or food allergies.

Family and Social History

Document a brief family history relevant to the chief complaint (e.g., family history of diabetes and cardiac disease in a patient presenting with chest pain). Social history mainly includes questions about smoking habits, alcohol consumption, sexual history, and illicit drug use. It might also be essential and relevant to ask about the patient’s financial and health insurance status, particularly in specific healthcare settings, to avoid ordering unnecessary tests and paying extra costs.

Physical Exam

Recording physical exam findings starts with the patient’s general appearance and vital signs, highlighting abnormal ones. It is important not to document or fabricate any findings that were not examined, as committing to such findings may have medical and medicolegal implications that are best avoided. Document all findings from the examined systems, including inspection, palpation, auscultation, etc. There is no need to document findings not pertinent to the chief complaint (e.g., neurological examination findings in a patient with a sore throat). Include important positive and negative findings for any given case [3].

Example:

A patient with abdominal pain

  • Important positive findings: Soft, non-tender abdomen, normal active bowel sounds
  • Important negative findings: No rebound tenderness, guarding, rigidity, or peritoneal signs
  •  

Assessment

It should capture the essence of the case and defend the rationale for further investigation. It usually includes an objective case summary, with differential diagnoses based on history and physical examination findings.

Plan

This section includes the investigations, medications, procedures, and consultations to be ordered or performed. The consultation time is crucial; the doctor’s name and recommendations must be promptly documented.

Disposition

This is usually the last part of the note. It indicates whether the patient will be admitted, discharged, or transferred to another facility. If discharged, follow-up and return instructions should be documented clearly [2-4].

Summary of all components in an ED Note

  • Chief complaint
  • History of present illness with pertinent positives and negatives
  • A brief review of systems
  • A focused past medical and surgical history
  • Pertinent medications and allergies
  • Family and social history, if relevant
  • Vital signs, highlighting any abnormal readings
  • A focused and appropriate physical exam
  • Assessment with differential diagnoses
  • Plan
  • Disposition

Few helpful suggestions during documentation

  • Place the date and time on all notes in the medical record.
  • Write notes clearly and legibly.
  • If you make a mistake, draw one line through it and sign your initials.
  • Document a focused but thorough history and physical.
  • Avoid using unclear abbreviations that are not commonly used.
  • Document vital signs and address abnormalities.
  • Document the results of all diagnostic tests that were ordered when appropriate.
  • When speaking to a consulting service, document the physician’s name and the time the call was made.
  • Document the patient’s response to therapy.
  • Document repeat examinations
  • Document your thought process (medical decision-making)
  • Avoid writing derogatory comments in the medical record.
  • Avoid changing or adding comments to medical records after completion. An addendum may be appropriate, but only if appropriately timed and dated.
  • Document all procedures performed.
  • If a patient leaves against medical advice (AMA), document that you have explained the specific risks of leaving and that the patient acknowledges and is aware of the risks.
  • Document plan for outpatient care and follow-up
  • If using an electronic medical record (EMR) instead of a handwritten one, all of the above sections, components, and suggestions apply [1,8,9].

Cardiac Monitoring (2024)

by Stacey Chamberlain

Definitions and Overview

Cardiac monitoring in the emergency setting is continuous monitoring of a patient’s cardiac activity in order to identify conditions that may require emergent intervention. These conditions include certain arrhythmias, ischemia and infarction, and abnormal findings that could signal impending decompensation. This chapter focuses specifically on cardiac monitoring or electrocardiography; additional methods of continuous hemodynamic monitoring in the emergency department (ED) include pulse oximetry, end-tidal CO2 monitoring, central venous pressure monitoring, and continuous arterial blood pressure monitoring. Of note, telemetry is the ability to do cardiac monitoring from a remote location; in practice, this is often a centralized system that might be located at a nursing station where multiple patients can be monitored remotely.

Cardiac monitoring differs from a 12-lead electrocardiogram in that it is done continuously over a period of time rather than capturing one moment in time in a static image. The benefit of this is that it captures transient arrhythmias and ectopic beats or monitors for changes over time. A disadvantage of cardiac monitoring is that typically, only 2 leads are displayed instead of a full 12 leads, giving a less comprehensive view of the heart and limiting its utility for looking for anatomic patterns. For example, on the 12-lead EKG, ED practitioners usually group the inferior, anterior, and lateral leads when looking for ischemic or infarct patterns. These may be less evident on a monitor with only two leads. Additionally, the static EKG allows the ED physician to carefully study it for subtle findings, for example, to make measurements of intervals, whereas in real-time monitoring, this is very difficult. In practice, both modalities are commonly used in conjunction for many ED patients.

The American Heart Association (AHA) published a consensus document in 2004 establishing practice standards for electrocardiographic monitoring in hospital settings, which was updated in 2017 [1,2]. These comprehensive documents outline the indications for cardiac monitoring, the specific skills required of the practitioner for cardiac monitoring, and specific ECG abnormalities that the practitioner should recognize. The 2017 update addressed the overuse of arrhythmia monitoring among certain populations, appropriate use of ischemia and QT-internal monitoring among select populations, alarm management, and documentation in electronic health records [2].

Cardiac monitoring is essential for those patients who are at risk for an acute, life-threatening arrhythmia and can also be used to evaluate for developing ischemia, response to therapy, and as a diagnostic tool. The AHA guidelines divide indications for cardiac monitoring in the inpatient setting into four classes based on varying degrees (level A, B, C) of evidence. Cardiac monitoring is considered indicated in patients in Class I. In Class IIa, it “is reasonable to perform” cardiac monitoring, whereas in Class IIb, it “may be considered.” For Class III, cardiac monitoring is not indicated as there is no benefit or there may actually be harm. Newer guidelines tailor the recommendations based on specific patient populations and whether the cardiac monitoring is for arrhythmia or continuous ST-segment ischemic monitoring [2]. Specific patient populations that are considered include patients with:

  1. Chest pain or coronary artery disease.
  2. Major cardiac interventions such as open heart surgery.
  3. Arrhythmias.
  4. Syncope of suspected cardiac origin.
  5. After electrophysiology procedures/ablations.
  6. After pacemaker or ICD implantation procedures.
  7. Pre-existing rhythm devices.
  8. Other cardiac conditions (acute decompensated heart failure or infective endocarditis).
  9. Non-cardiac conditions (e.g., post-conscious sedation or post-non-cardiac surgery).
  10. Specific medical conditions (e.g., stroke, imbalance of potassium or magnesium, drug overdose, or hemodialysis).
  11. DNR/DNI status.

Table 1 lists Class I-III recommendations. The AHA Scientific Statement provides a more comprehensive and detailed list.

Table 1 – Select Indications for Cardiac Monitoring

Class I Indications

Early phase ACS or after MI

 

After open-heart surgery or mechanical circulatory support

 

Atrial tachyarrhythmias

 

Symptomatic sinus bradycardia

 

2nd or 3rd degree AV block (exception as noted below for asymptomatic Wenckebach)

 

Congenital or genetic arrhythmic syndrome (e.g. WPW, Brugada, LQTS)

 

After stroke

 

With moderate to severe imbalance of potassium or magnesium

 

After drug overdose

Class IIa and IIb Indications

Non-sustained VT

 

Asymptomatic, significant bradycardia with negative chronotropic medications initiated

 

After non-cardiac major thoracic surgery

 

Chronic hemodialysis patients without other indications (e.g. hyperkalemia, arrhythmia)

Class III Indications

Patients with chronic atrial fibrillation, sinus bradycardia, or asymptomatic Wenckebach who are hemodynamically stable and admitted for other indications

 

Asymptomatic post-operative patients after non-cardiac surgery

 

DNR/DNI patients when the data will not be acted on and comfort-focused care is the goal

Ischemia Monitoring

Continuous ST-Segment Ischemia Monitoring was highlighted in the 2017 AHA guidelines as a specific indication for cardiac monitoring for patients most at risk for ischemia. Older monitors may not have this capability, but more modern monitors are programmed with automated ischemia monitoring that identifies abnormal ST-segment elevation or depression; manufacturers do not automatically enable this capability, and it may be turned on or off. To reduce unnecessary alarms, it is recommended (IIa level) to enable this function only in high-risk patients in the early phase of ACS and to individualize which lead should be prioritized based on the coronary artery suspected to be affected by an ischemic process. High-risk patients would include those being evaluated for vasospastic angina, those presenting with MI, post-MI patients without revascularization or with residual ischemic lesions, and newly diagnosed patients with a high-risk lesion such as a left main blockage.

QTc Monitoring

QTc monitoring aims to assess the safety of QT-prolonging medications and avoid Torsade de Pointes (TdP). Most hospitals do not have fully automated continuous QTc monitoring, so QTc monitoring and measurements may need to be performed manually or semi-automated with digital calipers. Regardless of the method, in general, recommendations for QTc monitoring are for patients with specific risk factors for TdP who are started on anti-arrhythmic drugs with a known risk for TdP (e.g., dofetilide, sotalol, procainamide, quinidine, and others), patients with a history of prolonged QTc started on non-anti-arrhythmic drugs with risk for TdP, those undergoing targeted temperature management, specific electrolyte derangements, and select drug overdoses. As with ischemic monitoring, QTc monitoring is not universally recommended for all patients, so consulting the 2017 guidelines for select patient scenarios is best.

Rhythm Interpretation

One of the most critical skills of an ED physician is in interpreting both static EKGs and interpreting arrhythmias on a cardiac monitor. A skilled practitioner must be able to diagnose common arrhythmias and be well-versed in the management of acute arrhythmias, recognizing which arrhythmias necessitate immediate action and which are less worrisome. Table 2 from the 2004 AHA guidelines lists the specific arrhythmias that the ED physician must be able to recognize. How and whether to treat an arrhythmia depends on many factors. The AHA has established algorithms for specific rhythms, including ventricular fibrillation (v-fib)/pulseless ventricular tachycardia (v-tach) and pulseless electrical activity (PEA)/asystole, as well as for non-specific rhythm categories such as bradycardia and tachycardia [3]. Additionally, they have published algorithms for clinical scenarios, including cardiac arrest, acute coronary syndrome, and suspected stroke.

The first step in the assessment of any rhythm is a clinical assessment of the patient. The premier issue of concern is if the patient is perfusing vital organs. A quick survey of the patient assessing mental status and pulses is essential to determining management. The management of a patient with v-tach will be substantially different if the patient is unresponsive and pulseless versus if the patient is awake with good pulses. As another example, the physician can quickly distinguish artifact from v-fib on the cardiac monitor by assessing the patient, as v-fib is not a perfusing rhythm.

The initial assessment of tachyarrhythmias (heart rate > 100) is to determine if the rhythm is “narrow-complex” (i.e., a QRS duration < 0.12s) or “wide-complex” (i.e., a QRS duration of 0.12s or greater). A narrow complex rhythm is considered a supraventricular rhythm (originating above the ventricles). Supraventricular tachycardia is a generic term encompassing any narrow-complex tachycardias originating above the AV node. Colloquially, when many practitioners refer to “SVT,” however, they are referring to a specific subcategory of supraventricular tachycardia called AV nodal re-entrant tachycardia (AVNRT). Wide complex tachycardias either originate in the ventricles or could originate in the atria and have an associated bundle branch block. Different criteria have been developed to help the practitioner distinguish between ventricular tachycardia and an SVT “with aberrancy” (i.e., aberrant conduction either due to an accessory path such as in Wolff-Parkinson-White or with a bundle branch block), the most well known of which are the Brugada criteria [4,5]. Practically speaking, many ED practitioners will assume the more dangerous and potentially unstable rhythm (v-tach) until proven otherwise; of course, the clinical picture and the patient’s vital signs are of utmost importance in determining the management of these patients. An excellent summary of this issue with rhythm strip examples is provided on the FOAM site “Life in the Fast Lane” [6].

While each rhythm has distinctive management, it is worth noting for the novice learner that only v-fib and pulseless v-tach warrant asynchronized mechanical defibrillation (i.e. “shocking” the patient). Many students are stunned upon observing an asystolic cardiac arrest code to learn that shocking a “flatline” (i.e., asystolic) patient is an inappropriate treatment perpetuated by fictitious TV shows and movies. For unstable patients with arrhythmias but still have palpable pulses, synchronized cardioversion may be used.

Regarding medications, for certain rhythms and clinical scenarios, only vasopressor types of medications are used (e.g., epinephrine for asystole). For other rhythms and scenarios, antiarrhythmic medications are used (e.g., amiodarone for v-tach). Atrioventricular (AV) nodal blocking agents are often necessary for supraventricular tachyarrhythmias. One author suggests using a five “As” approach to treating emergency arrhythmias, keeping in mind the medications adenosine, amiodarone, adrenaline (epinephrine), atropine, and ajmaline [7]. Ajmaline is an antiarrhythmic that is not commonly used in English-speaking countries where procainamide is more common as an alternative to amiodarone for unstable v-tach.

Additional interventions may include pacemaker placement for symptomatic heart blocks. In many cases, the ED practitioner must also determine the underlying precipitant of the arrhythmia and tailor treatment to that cause. The emergency physician must familiarize himself with each rhythm and its unique management in any given clinical scenario.

At the end of this chapter, some good internet resources for the ED practitioner to practice interpreting EKGs and cardiac rhythms are provided.

Case Example

A 44-year-old male patient with a history of hypertension and end-stage renal disease on hemodialysis presents with shortness of breath after missing dialysis for 6 days. He reports gradual onset shortness of breath associated with orthopnea and increased lower extremity edema. He denies chest pain or palpitations. He does not have any cough or fever. On physical exam, he is in no distress, afebrile with a heart rate of 60, respiratory rate of 20, blood pressure of 140/78 mmHg, and oxygen saturation of 98% on room air. He has a regular rate and rhythm without murmurs and has crackles bilaterally to the inferior 1/3 of the lung bases and 1+ pitting edema of the bilateral lower extremities.

You decide to get an EKG, which shows the following:

Figure 1 (EKG from http://www.lifeinthefastlane.com)

You send a blood chemistry test, place the patient on a cardiac monitor, and one hour later note the following on the monitor:

Figure 2 - (EKG from liftl.com)

What are the indications for cardiac monitoring in this patient? What EKG abnormalities do you see? What does the rhythm strip show? What is the treatment?

Case Discussion

The ED practitioner should recognize potentially life-threatening conditions that a patient who has missed hemodialysis is at risk for are fluid overload (leading to pulmonary edema) and hyperkalemia. This patient could be considered to meet the Class I monitoring criteria for “needing intensive care” and possibly with “pulmonary edema”; however, even if the patient had no symptoms, the patient is indeed at risk for an acute life-threatening arrhythmia that would necessitate cardiac monitoring.

The EKG demonstrates peaked T waves indicative of acute hyperkalemia. Given the clinical picture of missed dialysis and the peaked Ts on the EKG, the ED physician should immediately initiate treatment for acute hyperkalemia without waiting for a confirmatory blood test (unless immediate point-of-care tests are available). If the patient’s hyperkalemia progressed, the patient could develop QRS widening with the morphology as shown on the rhythm strip called a “sine wave.” This dangerous finding could precipitously deteriorate into a life-threatening arrhythmia such as pulseless v-tach with cardiac arrest and should prompt immediate action. It is important to note that hyperkalemia can manifest in a variety of different EKG findings and does not always follow a consistent pattern from peaked Ts to QRS widening to sine waves; therefore, the patient should be treated at the first indication of any hyperkalemia-related EKG changes.

Conclusions

Cardiac monitoring is an important tool to monitor patients at risk for acute arrhythmias (including those at risk specifically for TdP) and acute or worsening cardiac ischemia. It can be helpful to immediately identify patients with life-threatening arrhythmias who need immediate intervention, to assess the response to medications for arrhythmias, and to help exclude arrhythmias as a likely etiology of a patient’s symptoms (e.g., a patient with syncope) [9]. Given the limited resources and the lack of benefits for many patients, the purpose and duration of cardiac monitoring should be carefully considered. Overuse can not only waste resources but can also contribute to alarm hazards, including “alarm fatigue,” where clinicians are barraged by so many false or nonactionable alarm signals that they become desensitized and do not respond to real events. Therefore, appropriate use and staff education are critical to maximizing the benefits of cardiac monitoring.

Expert Opinion: Luis Vargas – ED Overcrowding

EMERGENCY DEPARTMENT OVERCROWDING

Dear students, emergency departments are suffering overcrowding since long time. There are various causes of this situation as well as solutions. It is better to know about ED overcrowding before your first shift. Dr. Luis Vargas from Colombia summarizes his lecture presented in 30th Emergency Medicine Congress of Mexican Society in Cancun.

Against Medical Advice and Elopement

In certain circumstances, patients may request to leave prior to completion of their medical evaluation and treatment. In this situation, it is essential for the last health care professional caring for the patient to document clearly why the patient left and attested that the patient had the mental capacity to make such a decision at that time (Henry, 2013). While some electronic documentation systems have templates in place to assist with this documentation, Table 2 provides basic information for against medical advice (AMA) discharge documentation that can be used to create a uniform template (Henry, 2013; Siff, 2011; Levy, 2012; Devitt, 2000).

What to do?

Interventions in the ED Discharge Process

DomainIntervention
ContentStandardize approach
DeliveryVerbal instructions (language and culture appropriate)
Written instructions (literary levels)
Basic Instructions (including return precautions)
Media, visual cues or adjuncts
ComprehensionConfirm comprehension (teach-back method)
ImplementationResource connections (Rx, appointment, durable medical supplies, follow-up)
Medication review

An attempt should be made to provide the patient with appropriate discharge instructions, even if a complete diagnosis may not yet be determined. Include advice for the patient to follow up with his physician, strict return precautions, and concerning symptoms that should prompt the patient to seek further care. It should also be made clear that leaving against medical advice does not prevent the patient from returning to the emergency department for further evaluation if his symptoms worsen, or if he changes his mind. Despite a common notion to the contrary, simply leaving against medical advice does not automatically imply that physicians are immune to potential medical liability (Levy, 2012; Devitt, 2000). If a patient lacks decision-making capacity to be able to adequately understand the rationale and consequences of leaving AMA and his condition places him at risk for imminent harm, involuntary hospitalization is warranted. In unclear circumstances and if available, psychiatry can assist in determining capacity, especially in the case of patients with mental health conditions.

Elopement is a similar process where patients disappear during the care process. While it is difficult to provide discharge paperwork for these patients, documenting the actions taken to find the patient is essential (e.g., searching the ED, having security check the surrounding areas). In addition, attempt to reach the patient by phone to discuss his elopement and any additional care issues or concerns. Documentation of these attempts or any additional conversation is very important (Henry, 2013; Siff, 2011).
