Background and Objectives The drugs most commonly implicated in major potential interactions are those used in the day-to-day clinical management of elderly patients with chronic diseases. This study is planned to evaluate the profile of drug-drug interactions in the medications prescribed to elderly population and also to identify the possible predictors for potential drug-drug interactions in the elderly. Methods This cross-sectional study included patients aged above 60 years with a minimum of two drugs in the prescriptions. Data were collected from medical prescriptions and patients' medical records. The data collected included demographic characteristics such as age, gender, height, weight, educational status, socioeconomic status, medical history, and medications prescribed. The prescriptions were analyzed for the potential drug interactions using Lexi-Interact™ Online, an online software to check drug-drug interactions. Results A total of 209 patients were included in the study, among them 104 (49.8%) were males and 105 (50.2%) were females. The mean number of medications received was 6.53 ± 2.15 per prescription. Around 138 (66%) patients received more than six medications. The mean number of potential drug interactions seen in the prescription of these patients was 3.17 ± 2.78. Around 18.2% patients had more than five drug interactions. Major drug interactions were observed in 21.42% of cases. Around 3.02% of drug interactions belonged to risk category X, i.e., to be avoided. Logistic regression analysis showed that age above 70 years was associated with the presence of drug interactions. Increased number of medication was independently associated with the occurrence of drug interactions. The presence of drug interactions was not associated with increased number of comorbidities. Conclusion A significant number of potential drug-drug interactions were seen in the prescriptions of elderly patients. Increasing age and polypharmacy were identified as the predictors of potential drug interactions.

Correlation of awareness of the disease with glycaemic control and diabetic complications among patients attending a tertiary care hospital ABSTRACT Introduction. The awareness level among diabetic patients varies across patient population based on many factors such as differences in the literacy of the study population, socioeconomic status, availability of diabetes education. Hence, it is important to study the same in our set-up to plan appropriate preventive strategies. The present research work attempted to assess the awareness level about diabetes and its complications among diabetic patients attending a tertiary care teaching hospital. Materials and methods. This is a hospital based, crosssectional study, done in diabetic patients attending a tertiary care teaching hospital in South India. The awareness level of the patient was assessed using a pretested questionnaire. The questionnaire had 25 questions (knowledge -18, attitude -4 and practice -3) and each correct answer was given a score of 'one' and each wrong answer was given a score of 'zero'. Patients were assessed clinically for the presence of micro and macrovascular complications and basic investigations were carried out. Metabolic control is assessed by HbA 1c level. Results. A total of 150 patients were included in the study. Approx. 52.6% of patients scored between 14 and 18 (sufficient awareness), 6.6% of patients had satisfactory awareness (KAP score 19-20) and 4% of patients had highly satisfactory awareness (KAP score > 20). Only eight patients had a score less than 10 (highly insufficient awareness) and 31.3% had insufficient awareness (KAP score 10-13). A positive correlation between educational qualification and awareness level was observed (r = 0.495, p < 0.001). Mean awareness score of patients who received diabetes education from physician and dietitian was significantly high when compared to other sources of patient education. Mean awareness scores were lower for those with various diabetic complications. There is a statistically significant negative correlation observed between awareness and HbA 1c values (r = 0.527, p < 0.001). Conclusion. Majority of the patients had sufficient awareness about the disease and about one-third of the patients had insufficient awareness about diabetes. The awareness level of the patients about the disease had a strong influence on the metabolic control, diabetic complications and also correlated with their educational status.
