Aims and Objectives To explore the context and the influence of night‐time care routine interactions ( NCRI s) on night‐time sleep effectiveness ( NSE ) and daytime sleepiness ( DSS ) of patients in the cardiac surgery critical‐care and progressive‐care units of a hospital. Background There exists a paucity of empirical data regarding the influence of NCRI s on sleep and associated outcomes in hospitalised adult cardiac surgery patients. Methods An exploratory repeated‐measures research design was employed on the data provided by 38 elective cardiac surgery patients (mean age 60.0 ± 15.9 years). NCRI forms were completed by the bedside nurses and patients completed a 9‐item Visual Analogue Sleep Scale (100‐mm horizontal lines measuring NSE and DSS variables). All data were collected during postoperative nights/days ( PON / POD ) 1 through 5 and analysed with IBM SPSS software. Results Patient assessment, medication administration and laboratory/diagnostic procedures were the top three NCRI s reported between midnight and 6:00 a.m. During PON / POD 1 through 5, the respective mean NSE and DSS scores ranged from 52.9 ± 17.2 to 57.8 ± 13.5 and from 27.0 ± 22.6 to 45.6 ± 16.5. Repeated‐measures ANOVA showed significant changes in DSS scores ( p < .05). NSE and DSS were negatively correlated ( r = −.44, p < .05), but changes in NSE scores were not significant ( p > .05). Finally, of 8 NCRI s, only 1 (postoperative exercises) was significantly related to sleep variables ( r > .40, p < .05). Conclusion and relevance to clinical practice Frequent NCRI s are a common occurrence in cardiac surgery units of a hospital. Further research is needed to make a definitive conclusion about the impact of NCRI s on sleep/sleep disruptions and daytime sleepiness in adult cardiac surgery. Worldwide, acute and critical‐care nurses are well positioned to lead initiatives aimed at improving sleep and clinical outcomes in cardiac surgery.
