Intervention Characteristics/Basic Study Process

Potential patients were referred to a highly experienced palliative care physiotherapist clinic. Patients were seen by the physiotherapist at three sessions, each lasting as long as 90 minutes. Intervention consisted of breathing retraining, simple relaxation techniques, activity pacing, and psychosocial support.

Sample Characteristics

The study reported on a sample of 30 patients with non-small cell lung cancer, small cell lung cancer, or mesothelioma (pleural effusion excluded) who experienced breathlessness not less than one month after completion of any active treatment; 68 patients were referred, 17 did not fulfill the criteria, 4 declined, and 2 were too ill to treat. Forty-five entered the study, and 15 deteriorated or died before completion. The median age was 71 years; 24 were men, and 6 were women.

Setting

The study was conducted in an outpatient clinic in the United Kingdom.

Study Design

  • Uncontrolled study
  • Nonrandomized
  • Referred patients

Measurement Instruments/Methods

Tools completed by the therapist at each visit

  • Current Respiratory Symptoms—adapted from two scales (Medical Research Council and Respiratory Symptom Questionnaire); patients were asked to score how often they were breathless, ranging from most or all the time to less than once a week
  • Functional Capacity Scale adapted from above tools; patients scored their ability to climb hills or stairs without breathlessness to experiencing breathlessness at rest
  • Sputum production scale

Self-assessment tools completed by patients at baseline and following the intervention (four to six weeks)

  • Rotterdam symptom checklist
  • VAS: breathing at worst and at best in the proceeding 24 hours as well as distress caused by breathlessness (0–10 where 10 = extreme distress)
  • Things that improve breathing (in the clinic, patients were taught techniques and coping strategies likely to improve their feeling of breathlessness); the patients were asked to score 20 helpful strategies at baseline and at the last visit on a VAS (1–10 where 10 = extremely helpful).
  • Quality-of-life questionnaire
  • Therapist recorded patients’ verbatim comments in free narrative form and added own comments.

Results

Statistical analysis of baseline data on 12 patients who were unable to complete the study compared to 30 patients who completed the study showed significantly lower Functional Capacity Scale scores (p = 0.04) at first assessment. For patients who completed the study, a highly significant (p < 0.001) change in frequency of reported breathlessness was found. A decrease existed in reported breathlessness, from 97% reporting it at least once or twice a day, 73% several times a day, and 27% most of the time to 27% experiencing dyspnea several times a day and 3% most of the time at the final visit. A statistically significant change was seen between study entry and completion (p < 0.001) in functional capacity. Overall, 19 improved function, 9 remained stable, and 2 deteriorated.

No change in sputum production was found.

Rotterdam symptom checklist:

Significant changes were seen in the physical distress scores and activity levels (no p value given). Change in psychological distress scores were borderline.

Degree of breathlessness:

Significant improvement (p < 0.001) was found in all three parameters—breathing at best, breathing at worst, and distress caused by breathlessness.

Intervention strategies:

On study entry, patients were asked to score 20 strategies that were likely to improve feelings of breathlessness. Examples of interventions include activity pacing, abdominal breathing, slowing down, relaxation exercises, not worrying, accepting the situation, and positive thinking.

Patients reported that all of the techniques they learned were helpful and improved breathlessness. Patients reported that massage and the use of bronchodilator drugs were not helpful.

Quality of life:

Significant improvements were seen in decrease in time spent lying down (p = 0.02), improved bodily strength (p = 0.03), and increase in things that made patients happy (p = 0.04). Patients reported an increased ability to do things and improved quality of life.

Qualitative data:

The following themes were extracted from the narrative data: difficulty adjusting, issues around death, effects of treatments, and therapies’ impact on daily life.

Limitations

The study was uncontrolled. A major limitation of the study is that it is a nonrandomized trial of referred patients. Impossible to know are the implied bias in patients who were referred or the true effect of the intervention without a control group. It was based on a prior study, with the time period shortened because of the loss of patients in the earlier study’s sample.
