Sleep Patterns During Hospitalization Following Hematopoietic Stem Cell Transplantation.

Purpose/objectivesTo characterize patient-reported and objective sleep assessments and provide a preliminary examination of the relationships among sleep, quality of life, and demographic or treatment factors.DesignA secondary data analysis using a descriptive-correlational design.SettingUniversity of Illinois Hospital and Health Sciences System.Sample40 patients undergoing a hematopoietic stem cell transplantation (HCT) hospitalized for the conditioning regimen, stem cell infusion, and immediate recovery period.MethodsEach patient wore a wrist actigraph continuously from the fourth day following HCT to the eighth day to objectively assess sleep patterns (total sleep time, sleep onset latency, sleep efficiency, wake after sleep onset, and number of awakenings). At the end of the five-day period, patients completed measures of sleep disturbance and quality of life.Main research variablesObjective sleep (total sleep time, sleep onset latency, sleep efficiency, wake after sleep onset, and number of awakenings), subjective sleep (sleep disturbance), and quality of life.FindingsThe mean total nighttime sleep (objectively obtained) was 232 minutes (SD = 71 minutes), with 14 patients (35%) sleeping less than three consecutive hours during one or more study days. Age was negatively correlated with patient-reported sleep disturbance. Patient-reported sleep disturbance was significantly associated with length of hospital stay. No correlations were found between patient-reported and objective sleep assessments.ConclusionsThis study objectively documents inadequate and irregular sleep in hospitalized patients undergoing HCT. Sole reliance on patient-reported sleep assessments may not represent the full extent of the problem.Implications for nursingAttempts to streamline care during the night by not waking patients for routine care unless indicated by the patient's condition (as advocated by the American Academy of Nursing) and providing supportive care for symptoms (such as diarrhea) during the night may reduce the number of awakenings and possibly improve overall sleep quality.
