title: Developing an outcome measure for excessive saliva management in MND and an evaluation of saliva burden in Sheffield.
abstract: There are few studies providing evidence to guide the management of oropharyngeal secretion problems in motor neuron disease (MND). There is a lack of a suitable outcome measure for evaluating management strategies. We applied several potential outcome measures for assessing excessive secretions to patients with MND who attended the Sheffield Care and Research Centre for Motor Neurone Disease between 21 November 2012 and 15 May 2013. These measures were the CSS-MND, a symptom rating scale, and the Drool and Wipe quotient, which were designed to semi-objectively measure patients' drooling. Of the 143 patients seen in clinic during the study period, 58 had symptoms of excessive secretions, and of whom 50 agreed to participate in the study. Semi-objective measures failed to effectively identify patients complaining of secretion problems. The CSS-MND had a relatively low internal consistency (Cronbach's alpha 0.539; n = 50); however, analysis of the inter-item correlations suggested the appearance of low internal consistency was because the scale was measuring a variety of saliva related symptoms that did not necessarily influence each other. The scale correlated well with patient reported symptom impact (r = 0.673, n = 50). In conclusion, the CSS-MND would be a useful outcome measure in studies assessing the management of oropharyngeal secretion problems.
