Oral Mucositis Index (OMI) of Schubert et al

Description

The Oral Mucositis Index (OMI) was developed to measure acute oral mucosal changes following bone marrow transplantation. It can be used to monitor the oral complications associated with cancer therapy and can help identify patients needing more aggressive intervention. The authors are from the Fred Hutchinson Cancer Research Center in Seattle.


 

Measures:

(1) atrophy (11 items)

(2) pseudomembrane (11 items)

(3) erythema (10 items)

(4) edema (2 items)

 

Atrophy sites:

(1) upper lip

(2) lower lip

(3) upper labial mucosa

(4) lower labial mucosa

(5) right buccal mucosa

(6) left buccal mucosa

(7) dorsal tongue

(8) lateral tongue

(9) ventral tongue

(10) floor of mouth

(11) soft palate

 

Pseudomembrane sites:

(1) upper lip

(2) lower lip

(3) upper labial mucosa

(4) lower labial mucosa

(5) right buccal mucosa

(6) left buccal mucosa

(7) dorsal tongue

(8) lateral tongue

(9) ventral tongue

(10) floor of mouth

(11) soft palate

 

Erythema sites:

(1) upper lip

(2) lower lip

(3) upper labial mucosa

(4) lower labial mucosa

(5) right buccal mucosa

(6) left buccal mucosa

(7) dorsal tongue

(8) lateral tongue

(9) ventral tongue

(10) floor of mouth

 

Edema sites:

(1) right buccal mucosa

(2) left buccal mucosa

where:

• Pseudomembranes may be scored: 0 if none, 1 if > 0 and <= 1 square cm; 2 if > 1 and <= 2 square cm; 3 if > 2 square cm.

 

oral mucositis index =

= SUM(points for all 34 items)

 

Interpretation:

• minimum index: 0

• maximum index: 102

• The higher the index, the more severe the oral mucositis.

• The maximum value in the study population was 65.

 

Performance measures:

• Cronbach alpha: 0.898 - 0.938

• Guttman split-half coefficient: 0.844 – 0.933
