Study Purpose

To evaluate the feasibility of a patient-controlled, cognitive-behavioral intervention for pain, fatigue, and sleep disturbance during treatment for advanced cancer and to assess the initial efficacy of the intervention.

Intervention Characteristics/Basic Study Process

Patients provided baseline measures, such as measures relating to demographics and a symptom inventory, received education, and underwent training to use an mp3 player loaded with 12 cognitive-behavioral strategies (relaxation exercises, guided imagery, nature sounds). Patients used the strategies as needed for symptom management for two weeks and kept a log of symptom ratings with each use. Following the two-week intervention, patients completed a second symptom inventory and an evaluation of the intervention. Clinic staff identified patients who met the eligibility criteria based on diagnosis and treatment and then were briefly introduced to the study and asked if a research nurse could visit to provide additional information. The research nurse met with interested patients, assessed symptoms, and completed eligibility screening. Study purpose and procedures were explained, and written informed consent was obtained.

Sample Characteristics

  • The sample was comprised of 30 patients (20% male, 80% female).
  • Mean age was 56.27 years (range 36–79).
  • All patients had advanced (recurrent or metastatic) cancer and were receiving chemotherapy or radiotherapy. Half of the patients had a diagnosis of gynecologic cancer. Patients had been diagnosed with lung cancer (n = 8), colorectal cancer (n = 6), and prostate cancer (n = 1).
  • Most patients were Caucasian, women, and had earned a bachelor’s degree or higher.
  • Almost all patients (n = 27) were taking two or more prescribed supportive medications to treat symptoms.
  • Studies were included if they included at least two of the following three symptoms:  pain rated 3 or higher on a 0-to-10 scale in the previous 48 hours, fatigue in the previous week, and sleep disturbance in the previous week. 
  • Studies were excluded if they involved postoperative or neuropathic pain.

Setting

  • Multisite
  • Outpatient
  • Midwestern United States
     

Phase of Care and Clinical Applications

  • Patients were undergoing multiple phases of care.
  • The study has clinical applicability for late effects and survivorship, end of life care, and palliative care.

Study Design

The study used a one-group, pre- and postintervention design.

Measurement Instruments/Methods

  • Demographic questionnaire and chart review form to record age, gender, education, race, ethnicity, cancer diagnosis, current treatments, and supportive medications prescribed, such as analgesics, steroids, psychostimulants, hypnotics, or sedatives
  • Symptom inventory, to measure
    • Pain severity, by means of four, 0-to-10 numeric rating scales for pain now, worst pain, least pain, and average pain in the last 24 hours
    • Fatigue severity, by means of four, 0-to-10 scales for fatigue now, worst fatigue, least fatigue, and average fatigue in the last 24 hours
    • Sleep disturbance, by means of a 0-to-10 scale rating sleep disturbance in the last 24 hours and, from the Pittsburgh Sleep Quality Index (PSQI), a verbal rating of sleep quality
  • Additional symptoms and their effects on daily functioning, as assessed by the MD Anderson Symptom Inventory (MDASI), which includes items measuring 13 common cancer-related symptoms and their effect on general activity, mood, work, relations with others, walking, and enjoyment of life
  • Treatment log book, in which patients tracked each time they used a cognitive-behavioral strategy. Data tracked were time of day; strategy used; and immediate pre- and posttreatment scores, on a 0-to-10 scale, regarding severity of pain, fatigue, and sleep disturbance
  • Poststudy evaluation, a 12-item survey created, for the current study, to assess patients’ perceptions of the acceptability of the study procedures. Among the items evaluated were time commitment; equipment; and questionnaires and factors relating to the patient-controlled, cognitive-behavioral intervention, such as length, variety, and usefulness.
     

Results

  • Symptom scores at two weeks did not differ significantly from baseline scores; however, significant reductions in pain, fatigue, and sleep disturbance severity were found in ratings made immediately before and after the use of a cognitive-behavioral strategy.
  • Mean pain scores decreased from 4.54 pretreatment to 2.77 posttreatment.
  • Mean fatigue scores decreased from 4.9 pretreatment to 3.44 posttreatment.
  • Average sleep disturbance scores decreased from 5.05 pretreatment to 2.81 posttreatment.

Conclusions

The patient-controlled, cognitive-behavioral intervention is feasible and may reduce the day-to-day severity of co-occurring pain, fatigue, and sleep disturbance.

Limitations

  • The study had a small sample size, with less than 100 patients.
  • The study had a risk of bias due to no control group.
  • The study used a convenience sample comprised of well-educated, primarily female patients—a sample that may not be representative of all populations.
  • Uncontrolled extraneous variables, such as supportive medication use, could have influenced symptom outcomes.

Nursing Implications

The findings support nurse education and the recommendation of the specified patient-controlled, cognitive-behavioral interventions for the management of pain, fatigue, and sleep disturbance. In regard to patient care and symptom management at all stages of cancer, nurses are the front-line educators of patients. This intervention supports the principle of autonomy for patients able to participate actively in care. Further study—a randomized, controlled trial to test the efficacy of the intervention for co-occurring pain, fatigue, and sleep disturbance—was under way at the time this study was published.
