The cost effective way to prevent spreading of microorganism?

Appeared in: KPSC Staff Nurse - 2018

Explanation

  • Hand hygiene is universally recognized as the single most important, simplest, and most cost-effective method for preventing the spread of infections in healthcare settings.
  • It is readily accessible at the point of care (e.g., alcohol-based rubs) and does not have the recurring per-use cost associated with disposable PPE like gloves, masks, or gowns.
  • Proper hand hygiene effectively removes or inactivates a wide range of pathogens from the hands, breaking the chain of transmission.
  • The World Health Organization's '5 Moments for Hand Hygiene' provides a clear framework for its application, emphasizing its fundamental role in patient safety.

Why Other Options Were Wrong

  • Option A: Wearing a mask is a specific intervention for preventing droplet or airborne transmission, not a universal, primary method for all microorganism spread. It is more costly and less broadly applicable than hand hygiene.
  • Option B: Gloves provide a barrier but are not a substitute for hand hygiene. Hands can become contaminated during glove removal, and gloves can transfer germs from one surface to another. They also have a per-item cost.
  • Option D: Wearing a gown is a form of contact precaution used when extensive contact with a patient or their environment is anticipated, or when there is a risk of clothing being soiled by infectious material. It is situational and the most costly option listed.

Clinical Relevance
  • Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain Cost-effective infection control measures as background academic context rather than a clinical decision trigger.
  • Adherence to hand hygiene is a direct measure of the quality and safety of patient care. It is the first line of defense against Healthcare-Associated Infections (HAIs).
  • Nurses have a professional and ethical responsibility to practice and promote correct hand hygiene to protect their patients, themselves, and their colleagues.
  • In resource-limited settings, the cost-effectiveness of hand hygiene is even more critical, as it provides a high level of protection for a minimal investment.
How to Approach the Question
  • First, analyze the keywords in the question: 'cost-effective' and 'prevent spreading of microorganism'.
  • The term 'cost-effective' is a crucial qualifier. It asks for the method that provides the best outcome for the lowest cost.
  • Evaluate each option based on this criterion. Masks, gloves, and gowns are forms of Personal Protective Equipment (PPE) that have a per-item cost and are used in specific situations.
  • Consider the most fundamental and universally applied infection control practice. Hand hygiene is taught as the cornerstone of infection prevention.
  • Conclude that hand hygiene is the most broadly applicable, least expensive, and highly effective method, making it the most cost-effective choice.
