Dysphagia and tracheostomy management in New Zealand intensive care units

Abstract

ABSTRACT Background: Speech-language therapists (SLTs) hold an important multidisciplinary team (MDT) role in managing swallowing, communication and tracheostomy weaning in intensive care units (ICUs). Yet, many ICUs do not have dedicated SLT time. In this study, we explored New Zealand ICU’s current practices to support benchmarking across the country and against international evidence-based practice. Methods: In part 1, we extracted New Zealand data representing 11 ICU MDTs across all regions from an international survey of 746 ICUs (26 countries). MDTs were asked about their dysphagia practice. In part 2, we conducted a national survey exploring tracheostomy practice in New Zealand. SLTs were asked about perceived roles, knowledge, skills and confidence in tracheostomy. Thirty-five SLTs responded to the survey, again, representing all New Zealand regions. Results: All ICUs had access to a SLT but none had dedicated SLT hours. ICU teams had variable awareness of evidence-based practice in dysphagia care. Swallowing rehabilitation was infrequent. The top two perceived barriers to standardized management of dysphagia were lack of access to SLT and flexible endoscopic evaluation of swallowing (FEES) equipment. In part 2, SLTs were experienced and confident but standardized protocols were infrequent and not all practices met current international evidence-based practice. SLTs’ reported barriers to best practice were MDT understanding of role, insufficient ICU-dedicated SLTs, training of nursing, and access to otolaryngology. Conclusions: Skilled, ICU-dedicated SLTs are needed in New Zealand ICUs to support more consistent and evidence-based practice. Access to FEES and time for rehabilitation and MDT education are needed.
