Primary objective of the study is to study the awareness regarding statins in patients. Secondary objective is to evaluate adherence to statin and antiplatelet therapy in patients and to find out awareness about statins side effects in patients and to evaluate control of hyperlipidaemia in patients receiving statins.Study site will be Cardiology OPD at tertiary care hospital.

Patients on statin therapy will be screened according to the inclusion and exclusion criteria. Consent from those participants will be obtained who fulfil the eligibility criteria. Prior to consenting patient will be given a patient information sheet to know the details of the study. If the patient is unable to read, then it will be read out by the investigator or impartial witness, In simple language. Once the consent has been obtained, ICD will be signed, retained by the principal investigator and a copy of ICD will be given to patient. Each patient will be assigned a unique study identification number. After taking consent from patient, patients’ prescription will be scrutinized. Patients demographic details including age, sex, occupation, education and social economic status by Kuppuswamy classification will be noted. Duration of statin therapy of the patient will be documented. And changes in the medication will be recorded from previous prescription carried by the patient and comorbid conditions will also be noted. Details of the prescription current visit will be noted down which will include the drug name, dose, schedule, duration, route of administration. Patients’ lab investigation report will be scrutinized. Patients’ lipid profile and blood glucose profile will be noted down. Patient will be administered drug awareness and adherence questionnaire. Answers to the questions will be noted in a 15-20 min interview of the patient. Drug awareness questionnaire for patients will consist of total 15 questions. Drug awareness is defined as understanding about the medications provided by physician with respect to name of medication, indications, frequency, dosage, side effects. The questions have responses graded on a Likert scale with 2 options (Yes, No). Selected questions have sub questions and their responses will be recorded in descriptive form. Drug adherence questionnaire will consist of 2 sections one for adherence to statin therapy and one for adherence to antiplatelet therapy. Each section will have 6 questions. The questions have responses graded on a Likert scale with 2 options (Yes, No)

Primary Variable for the study will be  Drug awareness Score . Secondary Variables will be as follows:

1. Duration of statin treatment 2. Mean participant score 3. % Of participants who responded Yes or No to each item and sub-questions 4. Corelation analysis with patient and disease factors, drug awareness score.

Sample size of 300 patients will be considered. Patients attending Cardiology OPD, meeting the inclusion/ exclusion criteria during the study period will be enrolled.

For statistical analysis ,

Continuous variables would be presented as mean ± standard deviation (SD) .

Categorical data (e.g., Gender, education status, socioeconomic status) will be expressed as percentage.

Drug awareness questionnaire and Adherence questionnaire with variables of prescription pattern will be analysed using descriptive statistics .
