Predictive Value of the New Zealand Secretion Scale (NZSS) for Pneumonia.

Accumulated pharyngo-laryngeal secretions have been associated with aspiration and pneumonia. While traditional secretion scales evaluate location and amount, the eight-point New Zealand Secretion Scale (NZSS) uniquely encompasses a responsiveness subcomponent. This prospective observational study investigated the predictive value of NZSS for aspiration and pneumonia. Consecutive inpatients (N:180) referred for flexible endoscopic evaluation of swallowing (FEES) were recruited (neurological 49%, critical care 31%, structural 15%, other 5% etiologies). Mean age was 63 years (range 18-95 years, S.D. 18). A standardized protocol was completed on 264 FEES (180 first FEES, 84 repeat FEES). Penetration-aspiration scale (PAS) (ICC = .89) and NZSS (ICC = .91) were independently scored by two raters. Aspiration of food and/or fluids occurred in 36% of FEES; 24% silently. Median NZSS was 3 (range 0-7); with silent aspiration of secretions in 33% of FEES. There was a significant correlation between NZSS and PAS (R = .37, p < .001). Incidence of pneumonia during admission was 46% and was significantly associated with PAS (p < .001), NZSS (p < .001), age (p < .001), and tracheostomy (p < .001). Of those who developed pneumonia, 33% had both high PAS (>5) and high NZSS (>4). Eleven percent of those who developed pneumonia had an elevated NZSS (>4) in the absence of aspiration (PAS < 6). This large study reports the significant relationship between accumulated secretions, airway responsiveness, and pneumonia. This comprehensive scale is a useful tool when carrying out endoscopic evaluation and has the potential to predict pneumonia in patients irrespective of their aspiration status.

Current approaches to reporting pharyngo-laryngeal secretions.

PURPOSE OF REVIEW: Accumulated secretions in the pharynx and larynx are associated with dysphagia, aspiration and pneumonia, as well as increased social, health and economic burden. This article reviews developments in the instrumental reporting of pharyngo-laryngeal secretions over the last 2 years. RECENT FINDINGS: Although the healthy pharynx and larynx is moist, accumulation of secretions is indicative of abnormality. Using standardized secretion scales allows early identification, quantification of risk in patients, and sensitive monitoring of patients over time. Nonstandardized and subjective secretion reporting is common in recently published research despite the validation of a number of publicly available tools. Research characterizing accumulated secretions has contributed to our understanding of pathophysiology associated with poor secretion management and may inform future treatment studies. SUMMARY: Routine and standardized reporting of secretions is critical for patient assessment and should be reported in the most standardized way possible. Further research investigating the clinical relevance and treatment of accumulated secretions relies on quantitative pharyngolaryngeal secretions reporting.
