A bstract Background Early identification of patients with an emergent large vessel occlusion (ELVO) ischemic stroke is crucial in the Emergency Department (ED), as they are the ideal candidates for endovascular therapy. With this study, we have attempted to use Vision, Aphasia, Neglect (VAN) screening tool in the ED for rapid identification of ELVO ischemic stroke and compared its performance with the National Institute of Health Stroke Severity (NIHSS) scale. Materials and methods A prospective observational study was conducted in the ED of a tertiary care hospital over 18 months among all suspected stroke patients. Vision, aphasia, neglect and NIHSS scores were calculated on arrival. Magnetic resonance imaging + magnetic resonance angiography (MRI + MRA) were taken as gold standard. Results This study found that VAN identified ELVO with 85.19% sensitivity ( p -value < 0.0001), 88.64% specificity ( p -value < 0.0001), and 87% diagnostic accuracy, with respect to the gold standard test. Vision, aphasia, neglect had a positive predictive value (PPV) and negative predictive value (NPV) of 82.14% and 90.7%, respectively. Time taken to perform VAN score in the ED was on average 2 minutes. National Institute of Health Stroke Severity detected ELVO with a sensitivity of 88%, specificity of 51.11%, a PPV of 53.33%, and a NPV of 88.4%. Diagnostic accuracy was 66%, and it took approximately 5 minutes to perform. When both scores were applied together for ELVO detection, NPV was 100%. Conclusion Vision, Aphasia, Neglect score as well as NIHSS scale are both tools for clinical prediction of ELVO with VAN having a better diagnostic accuracy and utility as a screening tool in the ED.

Background: Prescribing drugs are an important skill which needs to be continuously assessed and refined accordingly. Many drugs especially antimicrobials and fixed dose combinations that maybe irrational are being prescribed. Hence, this study was undertaken to analyze the rational prescribing guidelines in post-operative patients which will help doctors to update their knowledge and improve their attitude toward selecting cost effective treatment. Aim and Objectives: The aims of this study were as follows: (i) To evaluate prevailing prescription trends and (ii) to evaluate rationality of prescriptions in post-operative cases of surgery, orthopedics, obstetrics, and gynecology (OBG), and Otorhinolaryngology (ORL) departments. Materials and Methods: A prospective observational study was conducted in post-operative wards of departments of surgery, orthopedics, ORL, and OBG of Dr. B. R. Ambedkar Medical College and Hospital, Bengaluru. The study duration was 15 months from December 2018 to March 2020 with a sample size of 2000. Results: In the present study, female preponderance (54.4%) was seen. Majority of the drugs (77.3%) were prescribed under brand name. The most common group of drugs prescribed was non-steroidal anti-inflammatory drugs (135%) and the antibiotic was Cephalosporins (77.5%). As per the World Health Organization (WHO) core prescribing indicators, 6.25 were the average drugs per prescription. Conclusion: According to the WHO core prescribing indicators, polypharmacy was observed and prescribing by generic name was also less. However, there was no irrational use of antibiotics in post-operative cases in our study which reduces the chances of development of antibiotic resistance. Practice of prescribing drugs from the essential drugs list (EDL) was less. The study suggests incorporating educative initiative, development of drug policy, and an EDL-based hospital formulary to ensure rational use of medicines.

Background: Diabetes mellitus (DM) is a chronic progressive metabolic disorder associated with microvascular and macrovascular complications in type 2 DM. Oral anti-diabetic drugs (OADs) play an important role in regulating raised blood glucose levels and compliance to treatment. Aims and Objectives: The aims of this study were to evaluate cost variations of different brands of drug formulations in the management of DM. Materials and Methods: This study was an analytical study. Costs of various OADs were obtained from January to March 2022 edition of current index of medical specialties India. The cost ratio and percentage of variation among different drugs in the treatment of DM available in Indian Market and Manufactured by different pharmaceutical companies were analyzed. Results: The percentage variation in cost among commonly prescribed single OADs was found to be highest for sulfonylurea group of dugs Glimepiride 1 mg tablet (1.366%), followed by Biguanides, Metformin 500 mg tablet (809%), α-Glucosidase inhibitors, and Voglibose 0.3 mg tablet (571%), while it was lowest for Glibenclamide 5 mg tablet (36%) and Acarbose 25 mg tablet (36%) of sulfonylurea drugs and α-Glucosidase inhibitors group of drugs, respectively. In combination drug therapy, Glibenclamide and Metformin combination (1.25 + 250 mg tablet) shows maximum variation (132%). Conclusion: There is a wide difference existing in the cost of various oral anti-diabetics available in Indian Market by different brands. The physicians must be aware of these variations and prescribe medicines accordingly, while considering the financial status of patient and also to promote adherence to treatment.
