Study Notes

Infection Control Overview

Infection control is vital for all healthcare professionals, underscored by the COVID-19 pandemic.
Objectives include understanding cleanliness, hand hygiene, environmental control, and preventing healthcare-associated infections (HAIs).

Cleanliness Practices

Cleanliness aims to minimize contamination and control infection spread.
Key areas to maintain cleanliness:
- Person: Maintain good hand hygiene.
- Task: Be aware of interactions with surfaces and equipment.
- Environment: Disinfect surfaces touched by patients and staff.

Definitions

Clean: A state with minimized infectious organisms, not merely visual cleanliness.
Soiled: Presence or potential exposure to pathogens on a person or surface.
Healthcare-Associated Infections (HAIs): Infections acquired in healthcare settings, necessitating strict preventive measures.

Infection Risk and Statistics

One in 31 patients in the U.S. has an infection linked to hospital care daily.
Serious implications arise when healthcare workers inadvertently infect patients.

Standard vs. Transmission-Based Precautions

Standard Precautions: Minimum prevention standards applicable to all patients, regardless of their health status.
Transmission-Based Precautions: Additional measures based on the level of interaction and expected exposure to body fluids.

Modes of Infection Control

Hand hygiene, appropriate use of PPE, and disinfection practices are crucial to breaking the infection link.
Emphasis on the importance of regular handwashing and use of hand sanitizer.

Hand Hygiene Importance

Hands are primary transmission vectors; effective hygiene reduces infection risks.
Five key moments for hand hygiene:
- Before patient interaction.
- Before aseptic procedures.
- After exposure to body fluids.
- After patient contact.
- After touching the patient’s environment.

Common Hand Hygiene Mistakes

Insufficient cleaning time, neglecting certain hand areas, and improper post-handwashing faucet usage can lead to contamination.

Personal Protective Equipment (PPE)

Types include gloves, gowns, masks, and goggles, which should be properly donned before and doffed after patient interaction.
Correct glove removal technique minimizes contamination risks.

Improving Communication While Using PPE

Face patients, ensure attention, minimize background noise, and utilize body language for clear communication.
Employ alternative communication methods for those with hearing or cognitive impairments, such as simple writing tools or speech-to-text apps.

Respiratory Hygiene

Limit spread of respiratory infections by covering coughs and sneezes, preferably using tissues or elbows.
Hygiene after coughing/sneezing is essential; wear masks during symptomatic periods.

Clinical Attire Considerations

White coats may facilitate infection transmission; therefore, consistent laundering is important, especially in clinical settings.
Adoption of "bare below elbows" policy in certain regions aims to minimize infection risk via clothing.

Summary of Isolation Precautions

Standard Precautions: Include hand hygiene, PPE use, respiratory hygiene, and cleaning of equipment.
Maintaining clean clinical attire and awareness of infection control practices is crucial for patient safety.### Personal Protective Equipment and Attire
Recommendations include short sleeves, no wristwatches, and no jewelry to minimize contamination risks while working with patients.
Scrubs and white coats should be washed daily to maintain cleanliness.
Closed-toe shoes are essential to prevent contact with bodily secretions.
Anti-microbial treated scrubs require following manufacturer directions for cleaning.
Additional protective measures may include wearing toe covers or shoe covers in specific environments.

Environmental Infection Control

Pathogens can be present on items that contact patients or treatment surfaces.
Equipment used with patients must be cleaned after each use, especially if there is a gap before reuse.
Items such as walkers, gait belts, and other tools should be left in the patient’s room when possible for exclusive use.

Soiled Linens Management

Use gloves when handling soiled linens to prevent contamination.
Ensure linens do not touch clothing during transfer to the soiled linen bin.
Avoid shaking linens to contain potential pathogens.
Soiled linens should be disposed of in designated bins, often color-coded blue.

Biohazard and Waste Disposal

Biohazard containers handle items exposed to infectious materials, marked by bright red signage.
Used PPE, like gloves and gowns, only goes into biohazard containers if visibly contaminated with blood or infectious materials.
Transport and dispose of used items properly; always perform hand hygiene afterward.

Transmission-Based Precautions

Isolation precautions are needed when a patient is suspected or confirmed to have a transmissible pathogen.
Different types of transmission-based precautions include contact, droplet, airborne, and novel respiratory precautions depending on the nature of the pathogen.

Contact Precautions

Implemented to minimize pathogen transmission through physical contact.
Requires hand hygiene, gowning, and gloving as standard practices.

Droplet Precautions

Aimed at reducing disease spread via respiratory droplets.
Involves additional protection measures, including wearing masks and face shields.

Airborne Precautions

Used for pathogens transmitted through airborne particles (e.g., tuberculosis, measles).
Requires the use of an N95 mask and ensuring isolation rooms are correctly maintained with airflow considerations.

Novel Respiratory Precautions

Introduced for pathogens like SARS-CoV-2, requiring a blend of contact, droplet, and airborne precautions.
Standard procedures include comprehensive PPE, including PAPR devices.

Importance of Laboratory Values

Laboratory values assess blood chemistry, helping diagnose medical conditions.
Knowledge of lab values needs to integrate safety considerations and critical thinking for therapy decisions.
Collaboration with the healthcare team is crucial when evaluating lab values to ensure optimal patient care.
Contextual factors such as a patient's medical history, medication, and nutritional status should inform lab value analysis.### Understanding Medical Plans and Laboratory Values
Understanding a patient's medical plan is crucial for effective intervention timing and addressing patient needs.
Anticipating physiological changes based on lab values outside the reference range is essential before and during physical therapy sessions.
Critical values indicate immediate health risks requiring urgent medical attention.

Age and Physiological Differences

Reference ranges for lab values such as erythrocytes (red blood cells), hemoglobin, and hematocrit vary by age due to growth and development dynamics.
Clinical plans must consider both age and medical condition when determining care strategies.

Clinical Context in Assessing Lab Values

Factors influencing lab values include acute/chronic conditions, time of day values were taken, medications, and recent nutrition/hydration status.
Preoperative orders may restrict food and hydration, potentially leading to low electrolyte levels.

Collaboration and Assessing Risk vs. Benefit

Collaborating with the interprofessional team is vital for determining patient care strategies.
Assessing the risk of initiating physical therapy against potential benefits is crucial for each patient.

Race, Ethnicity, and Genetic Considerations

Race and culture are not typically used as shortcuts in making medical decisions, despite genetic variability.
Establishing clinical lab reference ranges does not rely on ethnic group considerations.

Sex and Gender Considerations in Lab Values

Sex refers to biological differences, while gender pertains to social constructs.
Hormone therapy significantly impacts lab chemistry, necessitating interpretation of lab results based on a patient’s affirmed gender during treatment.

Complete Blood Count (CBC) Overview

CBC tests measure white blood cells, red blood cells, hemoglobin, hematocrit, and platelets; providing crucial health insights and aiding in differential diagnosis.
Therapists should gather additional objective data beyond CBC results for a comprehensive care strategy.

White Blood Cell (WBC) Considerations

WBCs are essential for immune function, identifying infections, inflammation, and certain cancers.
Newborns exhibit higher baseline WBC counts compared to adults.
Critical values for leukocytes indicate potential life-threatening conditions requiring immediate intervention.

Isolation Precautions

Patients with low absolute neutrophil counts are at increased risk for infection; protective isolation protocols may be necessary.
Protective isolation includes single-patient rooms, adequate ventilation, and staff wearing PPE.

Analyzing Elevated WBC Levels

Elevated WBC counts can indicate leukocytosis; levels exceeding 100,000 may lead to leukostasis with increased organ damage risk.
Important to collaborate with nursing staff regarding therapy session timings based on WBC trends.

Analyzing Decreased WBC Levels

Low WBC counts (leukopenia) are associated with increased infection risk; vigilance for signs of infection is essential during therapy.

Red Blood Cell Considerations

RBCs transport oxygen and carbon dioxide; abnormal levels can indicate various health conditions.
Erythrocytosis (increased RBCs) heightens risks for vascular occlusive events like myocardial infarction and stroke.

Hemoglobin Analysis

Hemoglobin carries oxygen; high levels can cause capillary clogging, while low levels can indicate anemia.
Critical hemoglobin values necessitate careful monitoring during therapy.

Hematocrit Overview

Hematocrit reflects the proportion of RBCs in blood; abnormal hematocrit levels suggest blood loss or fluid imbalance.
Elevated hematocrit (polycythemia) carries similar risks to elevated RBC counts, including thromboembolic events.

Clinical Monitoring and Safety

Continuous monitoring of vital signs, especially oxygen saturation and signs of fatigue, is crucial in managing patients with variable blood parameter values.
Educating patients on orthostatic hypotension is important for fall prevention during therapy interventions.
