*4.6. Limitation of the Present Review*

In the present review, the literature search was performed based on only three electronic databases (PubMed, Scopus, and ProQuest). Further, the systematic review was limited to the articles published between 2000 to 2022 and restricted to studies published in English. Due to the limited number of papers published and the diversity in the items present in the questionnaire, a meta-analysis for the present study was performed with three articles with similar items. However, the outcome of the current review on MIPs' knowledge and precautionary standards regarding HCAIs may limit the application of the result to the vast population.
