Hospital acquired Pneumonia (HAP)

Definition & Types of Hospital Acquired Pneumonia (HAP)

infection acquired in the course of hospital stay.

It is divided into early hospital acquired pneumonia HAP (within 48 hours) of hospital admission and it is mostly due to and treated like community acquired pneumonia (CAP) which is (The infection acquired before hospital entry because the organisms are the same ) AND late HAP after 48 hours of hospital admission because the causative organisms are quite different, more resistant to ordinary antibiotics , difficult to treat and associated with longer ICU stay and higher mortality.

At-risk patients:

1- Severe underlying diseases or associated multiple serious co-morbidities like diabetes, renal diseases or cancer.

2-Immunosuppresion like cancer patients receiving chemotherapy or AIDS patients.

3-Intravascular devices as central venous lines inserted into big veins like internal jugular or subclavian to measure superior vena Caval pressure to guide fluid management.

4-mechanical ventilation causing ventilator associated pneumonia (resistant organisms and difficult to treat)

Causative organism

1- Early HAP : pneumococci, H. influenza

2- Late HAP:  Gram negative organisms (Klebsiella/E. coli/Pseudomonas) and methicillin resistant Staph. Aureus which are resistant organisms.

SYMPTOMS of Hospital Acquired Pneumonia

Common Symptoms
  • Cough: A new or worsening cough that often produces thick, greenish, yellow, or pus-like (purulent) phlegm.
  • Fever and Chills: A high body temperature accompanied by shivering or rigors.
  • Shortness of Breath (Dyspnea): Difficulty breathing, rapid breathing (tachypnea), or an increased need for oxygen.
  • Chest Pain: Sharp or stabbing chest pain that typically worsens when taking a deep breath or coughing.
  • General Malaise: Extreme tiredness, fatigue, body aches, or a general feeling of being unwell.
  • Gastrointestinal Changes: Loss of appetite, nausea, or vomiting.
  • Rapid Heart Rate: An elevated heart rate (tachycardia).
    Special Considerations in Older or Critically Ill Adults
    • Mental Confusion: In older adults or patients with dementia, a sudden change in mental state or new-onset delirium is frequently the very first sign of HAP, even before a fever appears.
    • Subtle or Hidden Symptoms: Patients on mechanical ventilators (ventilator-associated pneumonia) or those who are heavily sedated or critically ill may not be able to describe chest pain or weakness. In these cases, doctors look for unexplained spikes in fever, rapid breathing rates, or a drop in blood oxygen levels

    Prevention of hospital acquired pneumonias

    Remember That Early Recognition is Always better While Prevention is The BEST.

    1-hand wash better with Soap and best with antimicrobial soap.

    2- Head elevation of the bed in intensive care units beds. All patients should be sitting at 30-45 degree unless contraindicated.

    3- Daily weaning trials with sedation vacation.

    4- Non-invasive mechanical ventilation (face/nasal masks) has less incidence of infection than the invasive mechanical ventilation using of endotracheal tube.

    5- Antimicrobial coated endotracheal tube.

    6- Early tracheostomy within seven days of endotracheal intubation.

    Is Hospital acquired Pneumonia Contagious?

    Hospital-acquired pneumonia (HAP) itself is not contagious in the traditional sense, but the specific bacteria causing it can be spread to others .
    Because HAP develops in a clinical setting, its transmission and risk profile look very different from the common cold or community flu.
    How the Bacteria Can Spread
    The underlying germs responsible for HAP (which are frequently strong, antibiotic-resistant bacteria like MRSA or Pseudomonas aeruginosa ) can be transmitted through:
    • Healthcare Workers and Equipment: Germs can inadvertently move between patients via the hands of medical staff, shared medical instruments, or clothing if strict protocols are not followed.
    • Respiratory Droplets: Like other lung infections, a patient coughing or sneezing can release droplets containing the bacteria into the immediate air.

    Why the Risk Differs for Visitors vs. Patients

    • Low Risk for Healthy Visitors: If you are a healthy person visiting a loved one with HAP, your immune system and healthy respiratory defense mechanisms make it highly unlikely that you will catch pneumonia from them. The bacteria primarily take hold when a person’s defenses are already down.
    • High Risk for Other Patients: People who are already hospitalized are uniquely vulnerable. Factors like recent surgery, breathing through a mechanical ventilator, a weakened immune system, or being confined to a bed make it much easier for these opportunistic bacteria to travel into the lungs and cause an active infection.

    Essential Prevention Checklist While You are in hospital Visit

    Hospitals use strict infection control measures to keep these germs from spreading to other patients. As a visitor or caregiver, you can protect everyone by following these steps:
    • Sanitize Instantly: Always wash your hands with soap and water or use an alcohol-based hand sanitizer immediately upon entering and leaving the patient’s room.
    • Follow Isolation Signs: Look for precautions posted on the door. If required, wear the provided personal protective equipment (PPE) such as gowns, gloves, or masks.
    • Do Not Visit While Sick: If you have a cough, fever, or runny nose, stay home to avoid introducing new germs to an already vulnerable patient.
    • Avoid Touching Equipment: Refrain from handling the patient’s IV lines, ventilator tubing, or monitors
