Implementing a systematic care pathway for management of dysphagia after cardiothoracic surgery.

OBJECTIVES

This longitudinal quality improvement study explored the impact of a new multidisciplinary dysphagia care pathway on swallow screening referrals, patient journeys and swallow outcomes in patients after cardiac surgery.

RESEARCH METHODOLOGY

The new dysphagia care pathway consisted of i) nurse chart review triaging using established risk factors, ii) nurse swallow screening (including a cough reflex test and water swallow test) and iii) rapid referral routes to speech pathology. All patients referred for swallow screening in 2020 after the commencement of the new dysphagia care pathway were included (n = 114). Data was compared to two historical, published data sets at the research site (n-41 in 2012-2013 and n = 121 in 2013-2016).

SETTING

Cardiovascular intensive care unit.

RESULTS

52% failed chart review and 29% failed cough reflex test. All patients who passed chart review and cough reflex test returned to a normal diet without need for speech pathology referral. Silent aspiration rates were high in those who failed chart review and the cough reflex test (42%, 43% respectively). For those who received a swallow screen, enteral feeding rates were 70% on first assessment and 27% by discharge from the unit in historical data (2013-2016). In comparison, in 2020, enteral feeding rates were 44% and 8% respectively.

CONCLUSIONS

Referrals for nurse swallow screening and speech pathology increased following the introduction of the care pathway. There has been a reduction in enteral feeding rates and length of enteral feeding at discharge. High rates of silent aspiration in those who fail screening suggests stepwise nurse dysphagia screening successfully picks up at-risk patients.
