Patient-Reported Effectiveness and Safety of Etoricoxib in Osteoarthritis (OA)

• Mean Change From Baseline in Patient WOMAC Domain Scores at Week 4 [ Time Frame: Baseline and Week 4 ] [ Designated as safety issue: No ]
  The change from baseline in 3 domain scores (pain, stiffness, and difficult in doing daily activity) of WOMAC at week 4 were measured. Each domain comprises of questions and VAS scales for scoring. For pain domain, 0 represents no pain and 100 represents extreme pain; for stiffness domain, 0 represents no stiffness and 100 represents extreme stiffness; for difficult in doing daily activity domain, 0 represents no difficulty and 100 represents most difficulty.
• Physicians' Global Assessment of Patients' Response to Therapy at Baseline Using IGART (Investigator Global Assessment of Response to Therapy) [ Time Frame: Baseline ] [ Designated as safety issue: No ]
  The IGART comprised of five categories: No response, poor response, fair response, good response, and excellent response. The percentage of participants who met the criteria of any of the 5 categories at baseline were collected.
• Physicians' Global Assessment of Patients' Response to Therapy at Week 4 Using IGART [ Time Frame: Week 4 ] [ Designated as safety issue: No ]
  The IGART comprised of five categories: No response, poor response, fair response, good response, and excellent response. The percentage of participants met the criteria of any of the 5 categories at week 4 were collected.
• Patient Assessment of General Health Outcome by EuroQoL-5 Dimensions (EQ-5D) at Baseline [ Time Frame: Baseline ] [ Designated as safety issue: No ]
  The percentage of participants who met the criteria of any of the 3 categories of EQ-5D at baseline and at week 4 were collected.The EQ-5D comprises of 5 dimensions (mobility, self-care, usual activities, pain / discomfort, and anxiety / depression) to be answered using a 3-categorical Likert's scales of: [No problem, Some problem, and Not able to carry out] for mobility, self-care and usual activities and [ Not present, moderate and extreme]for discomfort and anxiety/depression
• Patient Assessment of General Health Outcome by EuroQoL-5 Dimensions (EQ-5D) at Week 4 [ Time Frame: Week 4 ] [ Designated as safety issue: No ]
  The percentage of participants who met the criteria of any of the 3 categories of EQ-5D at baseline and at week 4 were collected.The EQ-5D comprises of 5 dimensions (mobility, self-care, usual activities, pain / discomfort, and anxiety / depression) to be answered using a 3-categorical Likert's scales of: [No problem, Some problem, and Not able to carry out] for mobility, self-care and usual activities and [ Not present, moderate and extreme]for discomfort and anxiety/depression
• Change From Baseline of Patient BPI (Brief Pain Inventory) Scores at Week 4 [ Time Frame: Baseline and Week 4 ] [ Designated as safety issue: No ]
  BPI consists of pain and pain interference domains. For pain (0=no pain to 10=extreme pain); for pain interference ( 0=no interference to 10= greatest interference).
• Patient TSQM (Treatment Satisfaction Questionnaire for Medication) [ Time Frame: Baseline and Week 4 ] [ Designated as safety issue: No ]
  Changes from baseline in Patient TSQM domain scores at week 4. TSQM consists of four domains (effectiveness; side effect; convenience and overall satisfaction), domain scores ranged from 0 (0=worst) -100 (100=best) were derived from converting the original Likert's scales to VAS scale.
• Change From Baseline in Number of Days Patient Miss From Work or House Keeping Work at Week 4 [ Time Frame: Baseline and Week 4 ] [ Designated as safety issue: No ]
• Change From Baseline in Patient-SF36 (Short Form 36) Domain Scores at Week 4 [ Time Frame: Baseline and Week 4 ] [ Designated as safety issue: No ]
  Weighted scores of the 8 domains of SF36 (i.e., physical functioning; role limiting due to physical problem; bodily pain; general health; vitality; social functioning; role limiting due to emotional problem; mental health) were scored on a scale from 0 ~100, with 100 representing the best possible functioning)

The purpose of this study is to collect disease burden of OA and the effectiveness and patient satisfaction of treatment by Arcoxia in the normal practice setting.
