The accuracy of the ‘Modified Evans Blue Dye Test’, for detecting aspiration pneumonia: A literature review.Objective: The ‘Modified Evans Blue Dye Test’ is a common procedure, used to detect aspiration pneumonia. The purpose of this study was to determine the accuracy of ‘Modified Evans Blue Dye Test’, across published clinical studies. Method: The speech pathologist conducted a literature review. Articles were collected from a variety of resources and analysed - using Dollaghan’s (2005) meta-analysis framework. Common themes were identified and categorized. Results: The speech pathologist identified 25 studies that examined the ‘Modified Evans Blue Dye Test’. Of these articles, only 10 met the criteria for inclusion. Studies reported failure, for the detection of small trace particulates. Studies were also of a decreased quality. Conclusion: Speech pathologists should be aware of the test’s limitations, when screening for aspiration pneumonia. Further research, into this topic is required.Key words: aspiration pneumonia, tracheostomy, ‘Modified Evans Blue Dye Test’, dysphagia. |

INTRODUCTION:
Aspiration pneumonia is a common medical condition, usually found in clients who have head and neck cancer (Davis & Stanton, 2004). Aspiration pneumonia is the inflammation of lungs and bronchial tubes, from breathing in foreign matter. This includes: food; fluid; and personal secretions. Aspiration pneumonia has significant medical consequences. Groher and Crary (2010) have argued that the cost of aspiration pneumonia is costly. It has been associated: with an increased length of stay in hospital; greater disability at 3 - 6 months; and a poorer nutritional status - during hospitalization. Guenter and Silkroski (2001), identified, that aspiration pneumonia can lead to: patient confusion; generalized organ system failure; malnutrition; dehydration; and compromise to the immune system. In combination, these symptoms can
