STUDY PURPOSE: To determine the effects of nonpharmacologic interventions on sleep quality in patients with lung cancer
TYPE OF STUDY: Meta-analysis and systematic review
DATABASES USED: Cochrane Central Register of Controlled Trials, MEDLINE, EMBASE, CINAHL, WHO International Clinical Trials Registry Platform Search Portal and Clinical Trials.gov
YEARS INCLUDED: Open start date through December 2016
INCLUSION CRITERIA: Nonpharmacologic intervention studies of any design for patients with lung cancer at any stage or illness and at any point in treatment, compromising at least 25% of participants who used sleep disturbance or quality as primary or secondary outcome by subjective or objective measure
EXCLUSION CRITERIA: None noted
TOTAL REFERENCES RETRIEVED: N = 1,259
EVALUATION METHOD AND COMMENTS ON LITERATURE USED: Two authors reviewed all studies for eligibility, and disagreements were resolved through discussion and third author as needed.
FINAL NUMBER STUDIES INCLUDED: N = 22
TOTAL PATIENTS INCLUDED IN REVIEW: 1,272
SAMPLE RANGE ACROSS STUDIES: ≤ 10 = 3 studies, > 10 < 100 = 16 studies , ≥ 100 = 3 studies
KEY SAMPLE CHARACTERISTICS: 82.4% of participants had lung cancer, > 66% had stage III or IV illness and were undergoing treatment.
PHASE OF CARE: Multiple phases of care
Interventions were grouped into 3 categories. Standard exercise and rehabilitation programs showed statistically significant improvements in sleep outcome measures in the short-term follow-up period (SMD -0.43, 95% CI; -0.68, -0.19, p = 0.0005). No differences were seen at the medium- and longer-term follow-up periods. Information, psychoeducation, and symptom screening interventions showed significant differences when compared to control at short-term follow up but was not measured at a later interval (SMD: -0.87, 95% CI, -1.21, -0.54, p, 0.00001). Mind-body interventions (2 studies with n < 100) showed large effect in treating sleep disturbances in patients with lung cancer in the short-term follow-up period (SMD: -0.88, 95% CI, -1.59, -0.16, p = 0.02), which were not observed at the medium follow-up period.
Although the three groups of interventions, exercise, information, psychoeducation, and mind-body interventions appear to improve sleep disturbances in the short term following the interventions, the data quality is low. The series of 22 studies looks at multiple interventions per category, some with small sample sizes, and uses a variety of delivery methods. Based on individual assessments and results of studies in other cancer populations, nurses may want to recommend the interventions to patients with lung cancer, at least to try. However, the call for ongoing research in the area continues, with specific focus on larger sample sizes, specific disease states, and single interventions.
The data for recommending use of nonpharmacologic interventions for sleep disturbances in patients with lung cancer are not sufficient. It is clear that they are feasible and may be effective in some instances. It does appear that they may improve sleep disturbance in the short term, but further work is needed to conduct larger studies and examine individual interventions and their components, as well as the treatment phase for the patient in which the intervention in applied. Based on assessment of patient condition and desire, nurses can use their judgment to make recommendations for patients with lung cancer to try nonpharmacologic interventions to improve sleep.
