Histograms showing the distributions of IDDSI-FDS scores assigned by survey respondents to 6 examples from the 16 case scenarios used in the study. Expected IDDSI-FDS scores are shown by asterisks. Details for these examples are as follows. (A) Appendix 1, Case 1: Diet texture prescription: level 5 (minced and moist foods) and level 2 (mildly thick drinks). The expected IDDSI-FDS score (ie, 6) was selected by 77% of the survey respondents. (B) Appendix 1, Case 2: Diet texture prescription: NPO (ie, no oral intake of foods or drinks). The expected IDDSI-FDS score (ie, 0) was selected by 90% of the survey respondents. (C) Appendix 1, Case 3: Diet texture: level 7 (regular foods) and level 0 (thin drinks). The expected IDDSI-FDS score (ie, 8) was selected by 97% of the survey respondents. (D) Appendix 1, Case 4: Diet texture prescription: a liquid-only diet spanning level 0 (thin drinks) to level 3 (moderately thick drinks). Given that level 3 also captures a food level on the IDDSI framework, this prescription would correctly be written as level 3 (liquidized foods) and level 0 (thin drinks). The expected IDDSI-FDS score (ie, 4) was selected by 51% of the survey respondents. (E) Appendix 1, Case 5: Diet texture prescription: NPO. The expected IDDSI-FDS score (ie, 0) was selected by 52% of the survey respondents. The finalized IDDSI-FDS scoring instructions capture the additional allowance of ice chips in therapy with a þ diacritic, such that the correct score would be 0þ. (F) Appendix 1, Case 6: Diet texture prescription: no oral intake of foods with level 1 (slightly thick drinks). The expected IDDSI-FDS score (ie, 1) was selected by 87% of the survey respondents.
