Patients will be recruited for 4 months which will be followed by data entry, data analysis, formulation of results and write -up. Thus the entire study will last for eight months. The questionnaire consists of mostly close ended questions with options in the form of yes/no/do not know. Some questions which require definitive answers have been provided with plausible options. Some questions have been left open ended so as to avoid ambiguity. The questionnaire is simple, in continuity and is translated into Hindi and Marathi languages so as to meet the needs of the local population.
