Objective:
To describe experience with a chronic pain management programme in Hong Kong Chinese patients.
Design:
Prospective study.
Setting:
Regional hospital, Hong Kong.
Participants:
Patients with chronic pain who participated in the first six Comprehensive Out-patient Pain Engagement programmes between 2002 and 2005.
Intervention:
Comprehensive Out-patient Pain Engagement is a 14-day structured, multidisciplinary out-patient programme conducted over 6 weeks. It includes pain education, cognitive re-conceptualisation, training in communication skills and coping strategies, graded physical exercises and functional activities training. It aims to improve patient function and quality of life, despite persistent pain.
Main Outcome Measures:
Changes in scores from baseline values after joining the programme, with respect to several assessment tools. These included the following: visual analogue pain scale, Pain Catastrophizing Scale, Patient Self-efficacy Questionnaire, Canadian Occupational Performance Measure, Medical Outcome Survey-Short Form 36 Questionnaire, and duration of physical tolerances, medication utilisation, and work status records.
Results:
Forty-five patients were available for analysis. After the Comprehensive Out-patient Pain Engagement programme, improvements in Medical Outcome Survey-Short Form 36 Questionnaire (role physical and vitality), Pain Catastrophizing Scale, Patient Self-efficacy Questionnaire, and Canadian Occupational Performance Measure were demonstrated (P<0.05). The duration of standing and sitting tolerances increased (P<0.05). An improvement in employment rate was also evident (P=0.01).
Conclusion:
The initial results of our management programme in Chinese patients with chronic pain are encouraging. This type of programme should be promoted more widely in this group of patients, as it appears to improve physical function, psychological well-being, and productivity.
