In this article, the development of an evidence-based guideline on eye irrigations to patients with eye chemical injuries in emergency departments will be illustrated. The development of this guideline was based on the PET model from John Hopkins Nursing Evidence-based Practice (JHNEBP), which is a powerful problem-solving approach to clinical decision-making. The three-steps PET model consists of practice question (P), evidence (E) and translation (T) was followed, in order to incorporate latest research evidence and best practices into patient care.

  1. To present the best available evidence regarding eye irrigation methods for patients with eye chemical injuries.
  2. To develop an evidence-based guideline regarding eye irrigations based on the best available evidence.

Critical Appraisal
Method to search for relevant evidence related to eye irrigations to patients with eye chemical injuries in emergency departments was described. Systematic search on eight databases using keywords search was demonstrated. 23 articles were identified and critically appraised.

Implication to Practice
Recommendations were made regarding four different aspects, which includes: time to commence eye irrigation, choice of irrigating solutions, temperature of irrigating solutions and optimal duration of eye irrigations. Subsequently an evidence-based guideline was developed to aid emergency nurses to initiate effective eye irrigations, a checklist was also developed for easier reference.
