+Flea-Borne Typhus? -- October 18, 2018


Los Angeles County Department of Public Health (LAC DPH) has identified a number of cases of flea-borne typhus associated with the homeless population in downtown Los Angeles and the Willowbrook area of Compton.

 

LAC DPH states, “flea-borne typhus, also known as murine or endemic typhus, is a disease transmitted by fleas infected with Rickettsia typhi or Rickettsia felis. Flea-borne typhus is endemic in LAC with cases detected each year. In recent years, the average number of cases reported to LAC DPH has doubled to nearly 60 cases per year; however, geographic clusters of the size are unusual. Most cases occur in the summer and fall months. In LAC, the primary animals known to carry infected fleas include rats, feral cats, and opossums. People with significant exposure to these animals are at risk of acquiring flea-borne typhus.”

 

When should EMS providers suspect typhus?

  • A fever of unknown cause, especially in patients at high risk (e.g., homeless, or those around feral cats or other mammals). 
  • Other symptoms include chills, body aches, headache, and rash.

 

What are recommended actions by emergency departments and other hospital-based clinicians?

Consider a diagnosis of flea-borne typhus in patients with a non-specific febrile illness with headache, myalgia, rash, and laboratory abnormalities including leukopenia, thrombocytopenia, and elevation of hepatic transaminases, without alternate identifiable etiology.

  • LAC DPH asks that all suspected cases of flea-borne typhus, particularly in persons experiencing homelessness and those with exposure to outdoor animals such as stray cats, opossums, pet dogs and cats, be reported to Los Angeles County DPH Acute Communicable Disease Control Program within 1 working day. 
  • Weekdays 8:30 AM – 5:00 PM: call 888-397-3993. For consultation: call 213-240-7941
         - After hours: call 213-974-1234, and ask for the physician on call.

Long Beach Health and Human Services

  • Weekdays 8:00 AM – 5:00 PM: call 562-570-4302
        - After hours: call 213-974-1234, and ask for the physician on call.

Pasadena Public Health Department

    • Weekdays 8:00 AM – 5:00 PM (closed every other Friday): call the Communicable Disease Control Program at 626-744-6089
           - After hours: call 626-744-6043.
  • LAC DPH recommends that treatment for typhus not be delayed for diagnostic testing which includes serologic testing for R.typhi IgG and IgM antibodies. As there can be cross-reactivity with other rickettsiae, LAC DPH also recommends testing for antibodies against R. rickettsii, the causative agent of Rocky Mountain Spotted Fever. http://www.publichealth.lacounty.gov/acd/TyphusTesting.htm
  • Doxycycline is the treatment of choice; the dose of doxycycline for adults is 100 mg orally BID.  Treatment should occur for a minimum of five days or until 48 hours after patient becomes afebrile. 

 

Are there concerns about contracting the disease if EMS or hospital personnel care for such patients?

  • There is no concern for person-to-person transmission therefore, standard precautions and PPE are indicated. 
  • No additional methods for cleaning of ambulances after transport of suspected patients are indicated.

If fleas are noted, consider removing clothing and place in a biohazard bag.

+Fentanyl Exposure for EMS Provider -- August 30, 2018


 

Fentanyl use as a drug of abuse has increased in the United States.  EMS providers are increasingly likely to encounter fentanyl in the line of duty.

 

Facts to know:

  • Fentanyl is a synthetic opioid that is more potent than heroin or morphine
  • Fentanyl can be present in many forms (e.g. tablet, capsule, powder, rocks, solutions)
  • Inhalation of fentanyl as an airborne powder is the most likely exposure route that would lead to harmful effects, but it is less likely to occur than skin contact.
  • Incidental skin contact is not expected to lead to harmful effects if the contaminated skin is promptly washed off with soap and water.

 

Signs and symptoms of fentanyl exposure include:

  • Respiratory Depression
  • Drowsiness or Unresponsiveness
  • Constricted or Pinpoint Pupils

 

Prevention:

  • PPE is effective in decreasing the risk of harmful effects from fentanyl exposure
    • Wear gloves to prevent skin exposure
    • NIOSH-approved respirators (“masks”) decrease the risk of inhalation exposure
    • Eye protection can prevent mucous membrane exposure

 

If exposure occurs:

  • Do not touch your eyes, mouth, nose or any skin after touching a potentially contaminated surface
  • Wash skin thoroughly with soap and water; Do NOT use hand sanitizers as they may enhance absorption through the skin
  • If you suspect clothing contamination, remove them via standard decontamination procedures

 

If an EMS responder exhibits signs or symptoms of fentanyl exposure:

  • Move away from the source and call for assistance
  • Administer naloxone per departmental protocols
  • Perform rescue breathing/airway management as needed
  • Administer CPR if indicated

+Seasonal Infuenza -- January 8, 2018


+Hepatitis A Outbreak in Los Angeles County -- September 21, 2017

 

The Los Angeles County Department of Public Health has notified the Emergency Medical Services (EMS) Agency of 10 cases of Hepatitis A amongst our homeless population or others at risk for Hepatitis A infections.

 

In San Diego County 421 cases of Hepatitis A infections including 16 deaths, primarily affecting homeless persons, injection and non-injection illicit drug users and individuals in dense living conditions with shared restrooms, were reported since November 2016.

 

At this time we recommend that all EMS Provider Agencies and Police Departments notify their staff who have direct contact with individuals from the identified population, of this outbreak and the need for vigilance relative to PPE use and hand hygiene. Although hand hygiene should be a part of daily clinical care both for the protection of the provider and the patient/client, outbreaks such as these bring this practice into the forefront of prehospital care. Hepatitis A virus is spread by oral contamination with feces which occurs when a person puts their contaminated hand in their mouth. This transmission can be prevented by PPE and good hand hygiene practices. These same practices are important for law enforcement personnel to follow to prevent exposure to disease.

 

The Center for Disease Control (CDC) recommends the following best practice related to hand hygiene and use of gloves for health care providers:

 

When and How to Wear Gloves

  • Wearing gloves is not a substitute for hand hygiene. Dirty gloves can soil hands.
  • Always clean your hands after removing gloves.
  • Steps for Glove Use:
    1. Choose the right size and type of gloves for the task
    2. Put on gloves before touching a patient's non-intact skin, open wounds or mucous membranes, such as the mouth, nose, and eyes
    3. Change gloves during patient care if the hands will move from a contaminated body-site (e.g., perineal area) to a clean body-site (e.g., face)
    4. Remove gloves after contact with a patient and/or the surrounding environment (including medical equipment) using proper technique to prevent hand contamination
      • Failure to remove gloves after caring for a patient may lead to the spread of potentially deadly germs from one patient to another
    1. Do not wear the same pair of gloves for the care of more than one patient

 

When Should an EMS providers and Law Enforcement Personnel Use Alcohol Based Sanitizers or Wash Hands

  • Before eating
  • Before and after having direct contact with a patient’s intact skin (taking a pulse or blood pressure, performing physical examinations, lifting the patient in bed)
  • After contact with blood, body fluids or excretions, mucous membranes, non-intact skin, or wound dressings
  • After contact with inanimate objects (including medical equipment) in the immediate vicinity of the patient
  • If hands will be moving from a contaminated-body site to a clean-body site during patient care
  • After glove removal
  • After using a restroom

 

When using alcohol-based hand sanitizer:

  • Put product on hands and rub hands together
  • Cover all surfaces until hands feel dry
  • This should take around 20 seconds

Each EMS Provider Agency should alert their providers to the CDC recommendations on who should be vaccinated against Hepatitis A.

Currently the Hepatitis A Vaccine is recommended for the following persons aged 1 year and older:

  • Persons who live/work in a community with a high rate of Hepatitis A (HAV)
  • For men having sex with other men.
  • For drug users.
  • Travelers to countries with high rates of Hepatitis A.
  • Persons with chronic liver disease.
  • Persons who receive blood products to help your blood clot (e.g. Hemophilia).
  • Persons working with HAV-infected animals or work with HAV in research setting.

The Hepatitis A vaccine is currently given to all children after 1 year of age - this occurred after 2000 - thus many of our EMS providers and law enforcement personnel may be unvaccinated. The Hepatitis A vaccine is given in two injections 6 months apart and confers 25 year immunity in most adults.

Message from the Medical Director -- October 6, 2017


 


+Paramedic to Assist caregivers or patient with self-administered emergency medication -- December 1, 2016

 

In this update I will:

  • Discuss the authority for paramedics to administer emergency medication including hydrocortisone for patients with congenital adrenal hyperplasia (CAH).
  • Define adrenal crisis and its causes
  • List signs and symptoms of adrenal crisis
  • Describe the appropriate field treatment for a CAH patient in the prehospital setting

Congenital adrenal hyperplasia or CAH are any of several types of genetic diseases (autosomal recessive) that can result in excessive or deficient production of sex steroids or cortisol. This can have a profound effect on the reactions of the body to stress including infection.

  • The adrenal glands sit on top of both kidneys and produces hormones including cortisol, aldosterone, and testosterone.
    Adrenal crisis is a life-threatening condition that occurs when there is not enough cortisol produced.
  • Congenital adrenal hyperplasia (CAH) is an autosomal recessive genetic disorder which results in improper hormone synthesis resulting in, with stress such as an infection, adrenal crisis.
  • Causes of adrenal crisis include deficiency anywhere along the pathway to cortisol production and release by the adrenal glands. CAH is one cause. Patients with dysfunction of the adrenal glands themselves (known as Addison™s disease), and those with disease of the pituitary may also have adrenal crisis with stressors.

 

Any of the following stresses to the normal physiology of a patient with CAH or other diseases of the adrenal gland can result in life threatening consequences:
I
nfection
Physical Stress

Dehydration
Surgery
Sudden discontinuation of medication
Injury to the pituitary or adrenal gland


Signs and symptoms are not specific for adrenal crisis “ so a high level of suspicion for this condition should be maintained for a patient with CAH. These signs and symptoms may include:

  • Nausea
  • Fever
  • Pallor
  • Confusion
  • Weakness
  • Tachycardia
  • Tachypnea
  • Hypotension/shock

IF LEFT UNTREATED CAN RESULT IN DEATH

 

CASE ILLUSTRATON
Let™s illustrate what we are discussing by presenting a case:
Paramedics respond to the home of a 2 year-old boy
Teenage sister states the boy began to have fever, vomiting and diarrhea several hours ago
She states the child has congenital adrenal hyperplasia
He is wearing a medical alert bracelet that states œadrenal insufficiency

The boy™s vital signs:
HR 180, RR-30,
Cap refill-delayed 3 secs
LOC- Responds to verbal by moving head and crying
Skins- Hot to touch

Sister states she tried to give the child a double dose (stress dose) of hydrocortisone (Solu-Cortef®) by mouth as prescribed by the physician, but the child immediately vomited it up.
She attempted to contact her parents but they did not answer her phone call.
Her mother usually gives him an IM injection of hydrocortisone (Solu-Cortef®) when he cannot tolerate medication by mouth.
She has his injection kit next to her.


What should the paramedic do?

What can the paramedics do?

Per State of California Title 22, Division 9, Prehospital Emergency Medical Services, Chapter 2, EMT 100063: Scope of Practice of EMT Assist patients with the administration of physician prescribed devices including but not limited to, patient operated medication pumps, sublingual nitroglycerin, and self-administered emergency medications, including epinephrine devices
Paramedics may perform any activity in the scope of practice of an EMT “ therefore can assist patients in delivering normally self-administered medications “ such as hydrocortisone in this case (other examples of emergency self-administered medications include albuterol, nitroglycerin, or epinephrine via autoinjector)

 

In summary

  • If a patient has CAH has symptoms of adrenal crisis, the EMT or paramedic can assist the patient, or patient™s caregivers in administering the medication (hydrocortisone (Solu-Cortef®) IM) which falls under both EMT and paramedic scope of practice
  • A paramedic should contact the base hospital with any questions
  • These patients must be transported to the hospital for further evaluation/treatment
  • This medication should be given as soon as possible and can be life saving

+The End of Life (AB15) Impacts on EMS System -- June 20, 2016

 

TO: The EMS Community

As many of you are aware, in late 2015, the California Legislature passed the End of Life Act (AB 15), which became law on June 9, 2016. This Act allows for terminally ill patients in California who are mentally competent adults to voluntarily request and receive a prescription for medication to end the patient™s life at a time of their choosing. This allows for a patient to have some control over the end of their life and gives patients dignity and comfort at the time of their death.

The law outlines many safeguards for the patient and includes language that the patient may rescind his/her wish to take the œaid-in-dying drug at any time.

In order to prepare the EMS system to care for these patients with respect for their wishes, there have been modifications to a number of key EMS Agency policies including Reference No. 814 “ Determination/Pronouncement of Death in the Field and Reference No. 815 “ Honoring Do Not Resuscitate Orders, Physician Orders for Life Sustaining Treatment, and the End-of-Life Option (Aid-in-Dying drug).

Please review these updated policies on our website under Resources/Prehospital Care Manual. Note a couple of new resources within Reference No. 815: Reference No. 815.3 provides an example of an attestation that the patient intends to take the Aid-in- Dying Drug within 48 hours. An attestation may or may not be available at the time EMS arrives at a home of a patient who has taken the aid-in-dying drug. Reference No. 815.4 is an algorithm, which is intended to provide guidance on the management of these patients. The goal is to honor a patient™s end-of-life option and provide comfort and guidance to the family.

We must also work collaboratively as EMS and hospital-based providers to make the best decisions on care and transport for the patient, and their families.

Sincerely,

Marianne Gausche-Hill, MD, FACEP, FAAP

Medical Director, LA County EMS Agency

+Zika Virus -- June 15, 2016

 

Zika virus is a flavivirus spread by the bite of the Aedes mosquito and is related to denque, yellow fever and West Nile viruses.

Originally reported in Uganda, the virus has now spread to many parts of the world including the United States (See Figures).

http://www.cdc.gov/zika/geo/active-countries.html

Incubation is 2-12 days and only 20% of patients bitten develop symptoms. Transmission between humans can occur via blood transfusion or sexual activity. Symptoms include fever, rash, conjunctivitis, joint pain, headache, and generalized weakness.

One of the most publicized complications is microcephaly in babies born of women infected with the virus during pregnancy (generally in the first trimester of pregnancy). Greater than 4000 cases have been reported in Brazil and now in other areas of the world.

Treatment of the disease is symptomatic meaning treating the fever and symptoms with acetaminophen (Tylenol) and other supportive care such as IV fluids if dehydrated. Ibuprofen (Motrin) should be avoided as co-infections with dengue do occur and use of nonsteroidal anti-inflammatory agents, such as ibuprofen, may increase risk of progression to hemorrhagic fever.

Testing for the virus can occur from blood, urine or cerebrospinal fluid specimens sent to local health departments. http://www.cdc.gov/zika/hc-providers/index.html

EMS providers should use universal precautions or standard infectious disease precautions (gloves and mask) when evaluating and transporting these patients to the emergency department. Exposure to blood or bodily fluids should be reported per normal guidelines and no additional precautions are necessary. Questions regarding exposures can first be directed to the Medical Alert Center who can contact Public Health.

ECG -- February 2017
 

Case presentation

A 57 year old man complains of mid-sternal sharp chest pain radiating to his back and jaw. The pain started while he was watching a football game on television, approximately 2 hours prior to calling 911. The patient denies any medical history. However, his wife endorses a history of untreated hypertension.

 

Case study

+What does this ECG show?

 
Rate 90 bpm
Rhythm Sinus vs Accelerated Junctional rhythm
ST Elevation >1mm in two or more contiguous leads? Yes
Which Leads? V2, V3, II, aVF
Reciprocal Changes? No
Other Abnormalities? PVC noted (see V4-V6) with wavy baseline

 

In the following diagrams, the green lines connecting adjacent P waves to T waves indicate the electrical baseline. ST elevations are shown in V2 and V3, representing an acute myocardial infarction (MI) in the anterior wall of the left ventricle.

Case study

 

ST elevations are more subtle in II and aVF, leads representing the inferior wall of the left ventricle. ST elevation is also noted in lead III, although it does not meet the >1mm criteria. While looking at lead II, one can also note that P waves are not reliably noted. While the rate argues for a sinus rhythm, this may alternatively represent an accelerated junctional rhythm. The choice between these two should not change management or additional interpretation of the ECG.

  Case study

 

There were no obvious reciprocal changes on this ECG. Close examination of the ECG demonstrates an isolated PVC recorded on the ECG.  While not inherently dangerous, the presence of ectopy (abnormal beats) in the setting of cardiac ischemia should be monitored closely.  Acute MI may lead to a variety of conduction abnormalities, including heart blocks, ventricular tachycardia, or ventricular fibrillation.

Case study

The paramedic should be aware of this risk, and closely monitor the patient for early intervention if they should develop cardiac dysrhythmia.

+How would you manage this patient?

The patient is having chest pain of a presumed cardiac cause, and the ECG shows STEMI. He should receive 162mg or 324mg PO aspirin, and may be given NTG 0.4mg SL every 5 minutes as needed for chest pain. The ECG should be transmitted to the STEMI Receiving Center for advance notification.  Frequent patient reassessments en route should include repeat vital signs, assessment of mental status, and monitoring for changes in rhythm.
