  METHODS
  The prospective study was conducted from August 1, 2013,to January 20, 2014, at Jinnah Postgraduate Medical Centre, Karachi, and comprised patients presenting with joint pain. A questionnaire was used to collect data, and patients were diagnosed using American College of Rheumatology / European League Against Rheumatism Rheumatoid Arthritis Classification Criteria. Data was analyzed using SPSS 20.
  
  
  RESULTS
  Of the 320 patients approached, 316(98.7%) filled the questionnaire. Eighty five (26.9%) were diagnosed as rheumatoid arthritis. Sixty (70.5%) were females and 25 (26.3%) were males. The frequency of rheumatoid arthritis was higher in people in 4th, 5th and 6th decades of life. Twenty five (7.9%) patients had positive family history, 77 (90.2%) were chronic sufferers and only 53 (16%) agreed to follow recommended immunosuppressive therapies. 212 (67.1%) patients belonged to highly literate class.
