Treatment satisfaction and dissatisfaction in patients with chronic low back pain

Abstract

This thesis explores treatment satisfaction and dissatisfaction in patients with chronic low back pain (CLBP). Chapters 1 and 2 provide background on CLBP, and treatment satisfaction and dissatisfaction. Chapter 3 presents study 1, the systematic review which identified research concerning treatment satisfaction and dissatisfaction in patients with CLBP. Findings indicated a need to define the concept, and establish appropriate measurement based on patient input and evidence to support the reliability and validity of items. Chapter 4 presents study 2, a qualitative study. Ten patients with CLBP taking medication and/or receiving physiotherapy were interviewed. A conceptual model of CLBP and a thematic map of treatment satisfaction and dissatisfaction were developed. Satisfaction was related to being 'happy' or 'pleased', and maintaining normal functioning. Treatment not working, causing discomfort, or negatively affecting health-related quality of life, as well as inconvenience of medication, lack of information, not feeling involved in treatment decisions, lack of trust and confidence in healthcare professionals, and being misdiagnosed or undiagnosed, were associated with dissatisfaction. Chapter 5 documents the development of the CLBP Treatment Satisfaction Questionnaire, based on patient input from study 2. Cognitive debriefing showed items were relevant and understood by patients. Chapter 6, study 3, explored the psychometric properties of the questionnaire. The longitudinal design involved data collection from 249 patients, some of whom participated in follow-ups. Results indicated that treatment satisfaction/dissatisfaction involves an appraisal of the following seven domains: 'Information Provided about Back Pain and Treatment', 'Burden of Back Pain', 'Impact of Back Pain and Treatment on Relationships', 'Satisfaction with the Treatment Process', 'Problems with Side Effects of Medication', 'Adherence to Physiotherapy', and 'Medication Acceptability'. Some evidence of reliability and validity are presented. This thesis concludes with Chapter 7, a discussion of the main findings of the studies, strengths and limitations, and recommendations for future research.
