Table 2 Patient and carer baseline and outcome measures for BIS Phase II RCT

From: The feasibility of a single-blinded fast-track pragmatic randomised controlled trial of a complex intervention for breathlessness in advanced disease

Baseline characteristic/outcome Instrument/measure
PATIENT  
Patient breathlessness Modified Borg [19] at rest and on exertion & identification of activity that makes breathlessness worst
Patient breathlessness at best/worst Visual Analogue Scale (VAS) [7]
Patient functional ability WHO performance scale [16]
Patient social functioning No. of times patient goes out of the house (average for last month)
Patient quality of life SEIQoL-DW [17]
Patient satisfaction with the service Qualitative (t1 – expectations of the BIS; t3/t5 – useful aspects of the service)
Patient critical incidents data Qualitative (e.g. identification of examples of difficulty getting help/medication/advice needed)
Patient anxiety Hospital Anxiety and Depression Scale [20]
Patient distress due to breathlessness Visual Analogue Scale for distress caused by breathlessness [7]
Patient mastery of breathlessness Mastery items from Chronic Respiratory Questionnaire [18]1
Patient use of other services Service use questions
CARER  
Carer quality of life SEIQoL-DW [17]
Carer satisfaction with the service Qualitative (t1 – expectations of the BIS; t3/t5 – useful aspects of the service)
Carer critical incidents data Qualitative (e.g. identification of examples of difficulty getting help/medication/advice needed)
Carer anxiety Hospital Anxiety and Depression Scale [20]
Carer's assessment of patient's breathlessness Modified Borg [19] at rest and on exertion & identification of activity that makes breathlessness worst
Carer's assessment of patient's breathlessness at best/worst VAS adapted for carer
Carer distress due to patient's breathlessness VAS adapted for carer – distress caused to carer by patient's breathlessness
Carer's assessment of patient's use of services Service use questions
Carer's social functioning No. of times carer goes out of the house (average for last month)
Caregiver burden Burden Interview [21]
Caregiver Appraisal Scale [22]
  1. 1Confirmation that it was valid to use these items in isolation of the whole Chronic Respiratory Questionnaire was received from its developer, Gordon Guyatt (email communication, 2005).
