1a = guideline/protocol; 1b = screening appropriate to 1a; 1c = validated/standardized cough outcome measure used; 2 = providers with expanded knowledge of guidelines/protocols and education provided and manual used; 3a = core management interventions appropriate to 1a; 3b = response assessed; 4 = reference to patient understanding as part of methods; 5 = reference to patient’s ability to use interventions in daily life. See Table 3 legend for expansion of abbreviations.
For the individual IF element scores, 0 = no fidelity to 6 = highest degree of fidelity possible; all scores are displayed as averages.
For the overall IF score ratings: good (36-48), fair (24-35), poor (≤ 23); all scores are displayed as averages.
