Prescription audit of a teaching hospital in South India using World Health Organization core prescribing indicators - A cross-sectional study.

Aim: World Health Organization (WHO) core prescribing indicators are highly standardized tools in reliably assessing the essential aspects of drug utilization pattern. It is critical that the rational use of drug prescribing is scrutinized for the utmost benefit of patient welfare. In this study, we aim to assess the prescription pattern and prescribing behavior of physicians using the WHO-recommended core prescribing indicators at a teaching hospital in South India. Materials and Methods: A prospective, descriptive cross-sectional study was conducted in the general medicine outpatient department of a tertiary care hospital for a period of 1 month in June 2019. A total of 600 prescriptions were sampled based on the WHO "How to investigate drug use in health facilities" document recommendation. The WHO guidelines and methods were observed to ensure data reliability. Descriptive statistical analyses such as frequencies, percentages, mean, and standard deviation were used to present the data. Results: The WHO core prescribing indicators analysis revealed that the average number of drugs per encounter was 2.38 ± 1.1 and only 796 (55.4%) of the drugs were prescribed by generic name. Whereas, the percentage of encounters prescribed with an antibiotic 44 (7.3%) and an injection 63 (10.5%) was less than the ideal recommendations as per WHO and 1265 (88%) of the drugs were prescribed from the National List of Essential Medicines. Conclusion: This study on prescription pattern audit done using the WHO core prescribing indicators highlights that prescriptions encountered with antibiotic and injection use were in accordance with the WHO recommendations.

Assessment on knowledge and practice of postexposure prophylaxis of human immuno-deficiency virus among staff nurses and paramedical workers at a tertiary care hospital in South India.

INTRODUCTION: Adequate knowledge about the presence of postexposure prophylaxis (PEP) against human immuno-deficiency virus (HIV) is imperative for health-care workers. This study focuses on the evaluation of the present knowledge and practice of nurses and paramedical workers on the post exposure prophylaxis against HIV. AIM: The aim of this study is to assess and compare the knowledge and practice of PEP against HIV among Staff Nurses and Paramedical workers. SUBJECTS AND METHODS: A descriptive cross-sectional questionnaire study about the knowledge and practice of PEP against HIV among Staff nurses and Paramedical workers done at a tertiary care hospital in South India. The analysis of the data was performed using SPSS software version 24. The statistical tests used to compare the knowledge between nurses and paramedical workers was Chi-square test. P < 0.05 was considered statistically significant. RESULTS: About 339 nurses and 66 paramedical workers participated in the study. An overall of 65.4% of the study participants had a good level of knowledge, higher (P = 0.000) among nurses (71.1%) compared to paramedical workers (36.3%). However, only 23% of nurses and 14.3% of paramedical workers received PEP after a needle prick injury. CONCLUSION: This study revealed a low-level practice of HIV PEP among staff nurses and paramedical workers despite their good knowledge. This can be improved by providing formal training sessions to the health care workers.

Neuroprotective Effect of Lercanidipine- A Novel Calcium Channel Blocker in Albino Mice.

BACKGROUND: The available conventional antiepileptics do not afford cure or prophylactic treatment and henceforth there is always a quest to explore new targets for management of convulsions. In this perspective, dihydropyridine calcium channel blockers have been investigated in various animal models of epilepsy. Lercanidipine, a newer dihydropyridine calcium antagonist, is a potential candidate with its favourable lipid profile and longer duration of action. OBJECTIVE: (1) To evaluate the anticonvulsant effect of lercanidipine alone and in combination with standard drug in adult male Swiss albino mice. (2) To evaluate the muscle relaxant and spontaneous locomotor activity of lercanidipine in adult male Swiss albino mice. MATERIALS AND METHODS: Adult male Swiss albino mice weighing 20-30g were used to study the anticonvulsant, muscle relaxant and spontaneous locomotor activity using electroconvulsometer, rotarod and actophotometer apparatus respectively. The mice were divided into six groups of six animals in each group. Group 1 and 2 served as control (vehicle treated) and standard group respectively. Standard drug used to evaluate anticonvulsant effect is phenytoin sodium 25 mg/kg I.P. whereas muscle relaxant activity and locomotor activity is diazepam 4 mg/kg I.P., Group 3 and 4 received lercanidipine 1 and 3 mg/kg I.P., respectively. Anticonvulsant models included group 5 and 6 and they were given combination of phenytoin sodium 12.5 mg/kg I.P., with lercanidipine 1 and 3 mg/kg i.p, respectively. Abolition or reduction of tonic hind limb extension was considered as index of anticonvulsant activity whereas the balancing time of the animals in rod was recorded to asses muscle relaxant activity. The locomotor activity was recorded for 5 minutes. The data were analysed with one-way Analysis of Variance followed by post-hoc 'Dunnett t-test'. RESULTS: Lercanidipine given alone in a dose of 1 and 3 mg/kg had significantly reduced the tonic hind limb extension. Combination of lercanidipine (3 mg/kg) and phenytoin had offered 100% protection. The results also revealed that the test drug didn't impair the motor coordination and locomotor activity in mice. CONCLUSION: The present study had demonstrated that lercanidipine could be potential novel candidate for the treatment of convulsions.

Midazolam premedication for Ketamine-induced emergence phenomenon: A prospective observational study.

OBJECTIVE: Ketamine administration is known to induce hemodynamic pressor response and psychomimetic effects which could be attenuated by appropriate premedication. The present study was designed to evaluate the effect of midazolam on hemodynamic stability and postoperative emergence phenomenon following ketamine anesthesia. METHODS: This was a prospective observational study including 30 adult patients with American Society of Anesthesiologists physical grades I and II scheduled for elective short surgeries under ketamine anesthesia. Patients were premedicated with midazolam (0.02 mg/kg intravenously) before the ketamine induction (1 mg/kg intravenously). Demographic data and hemodynamic variables were observed during the perioperative period. Pain score by visual analog scale score and psychomimetic effects were recorded postoperatively. FINDINGS: The mean ± standard deviation of heart rate, systolic blood pressure, diastolic blood pressure, and respiratory rate were decreased postoperatively (85.3 ± 11.4, 120.7 ± 8.2, 79.2 ± 5.5, 13.5 ± 1.8, respectively) compared to intraoperative period (88.53 ± 14.1, 123.83 ± 13.8, 83 ± 9.1, 14.13 ± 2.0, respectively). There was statistically significant decrease in systolic (P = 0.03) and diastolic (P = 0.002) blood pressure, but not with heart rate and respiratory rate. Eighty percent of patients had no pain at ½ hour and 1 hour, while this increased to 90% at 2 hours postoperatively. Mild emergence delirium was noted in 13.3% and 16.7% at ½ hour and 1 hour, respectively, which decreased to 13.3% at 2 hours. Dreams were noticed in 20%, 27% and 10% of patients at ½ hour, 1 and 2 hours after surgery, respectively. CONCLUSION: Midazolam premedication in ketamine anesthesia effectively attenuated the hemodynamic pressor response and postoperative emergence phenomenon. Hence, the combination of midazolam with ketamine can be safely used for short surgical painful procedures in adults.

Fixed drug eruptions caused by cross-reactive quinolones.

Fixed drug eruptions (FDE) are the common dermatological adverse drug reaction accounts for 16-21% of all cutaneous drug reactions in India. Drugs most frequently implicated in FDE are antimicrobials, anticonvulsants, and nonsteroidal antiinflammatory drugs. Here, we report a rare case of bullous FDE due to ciprofloxacin followed by ofloxacin administration.
