Efficacy of Interventions Based on WHO Multimodal Hand Hygiene Improvement Strategy in a Tertiary Care Hospital in Eastern India: A Quasi-Experimental Study.

The study aimed to evaluate the efficacy of the World Health Organization (WHO) multimodal hand hygiene improvement (WHO-5) strategy in enhancing hand hygiene compliance among health care workers at a tertiary care hospital. The interrupted time series study included preintervention, intervention, and postintervention phases, with 2 points of observation each during the pre- and postintervention phases. The baseline hand hygiene compliance was 16%, which improved to 43.9% after the intervention. Health care workers were 4 times more likely to adhere to proper hand hygiene postintervention (odds ratio [OR], 4.117). Independent predictors of hand hygiene compliance included the week of observation (week 3: adjusted odds ratio [AOR], 0.872; week 5: AOR, 3.427; and week 7: AOR, 4.713), health care worker type (consultants: AOR, 0.964; residents: AOR, 2.187; and interns: AOR, 6.684), daytime (AOR, 1.232), and "after" type of hand hygiene opportunity (AOR, 1.577). No significant differences were found in knowledge, attitude, and practices pre- and postintervention, and the interventions' effect was sustained and increased over time, supporting implementation in hospitals across India.

Association between ivermectin treatment and mortality in COVID-19: A hospital-based case-control study.

Purpose: This study was designed to test the hypothesis that exposure to ivermectin in early disease prevents mortality due to COVID-19. A secondary objective was to see if the drug has any impact on the length of hospital stay among the survivors. Methods: It was a hospital-based retrospective case-control study conducted at a tertiary teaching hospital in India. All patients with a diagnosis of COVID-19 who were admitted between 1st April and 15th May 2021 and received inpatient care were included. Important variables like demographic details, dates of admission and discharge or death, symptoms at the time of admission, comorbidities, severity of illness at the time of admission, whether ivermectin was administered or not during the course of the illness and other treatments received as part of the standard of care were retrieved from the medical records. Results: Of the 965 patients who received inpatient care, 307 died during their hospital stay while 658 were successfully discharged. The proportion of cases treated with ivermectin was 17.26% among the non-survivors (53/307) and 17.93% among the survivors (118/658). The effect was statistically insignificant (crude OR = 0.954; 95% CI: 0.668-1.364, P = 0.80). Among the survivors, the median length of stay was 11 days for patients who received ivermectin (IQR: 7-15) as well as for those who did not (IQR: 7-16). Conclusion: This study did not show any effect of ivermectin on in-patient mortality in patients with COVID-19 and there was no effect of the drug on the length of hospital stay among the survivors.

Clinical utility of MRI in acute stroke beyond reperfusion therapy.

Background: Stroke is primarily a clinical diagnosis. It can be hemorrhagic or ischemic in etiology. Computed tomography (CT) brain is usually the initial investigation in most patients with suspected stroke. Although it has excellent accuracy in diagnosing hemorrhage, ischemic changes may not be apparent in the first few hours. Some centers use focused magnetic resonance imaging (MRI) studies to help in selecting appropriate patients for reperfusion therapy. However, clinicians often use this investigation even when reperfusion therapy is not being considered. This study aims to find out whether doing an MRI in addition to a CT scan has any clinical utility in this situation. Primary Objective: To determine the proportion of patients who undergo a change in their management based on MRI findings. Secondary Objectives: 1. To determine the time duration from the onset of symptoms to presentation at the hospital. 2. To determine the time duration from presentation to the hospital to get CT performed. 3. To determine the proportion of patients who had MRI in addition to CT. 4. To determine the time duration from CT performed to MRI performed. Materials and Methods Study Design: Retrospective, descriptive observational study. Inclusion Criteria: Patients above age 18 admitted at a tertiary hospital with a clinical diagnosis of stroke between 1/8/2018 and 30/7/2019. Exclusion Criteria: Patients who had already undergone MRI before presentation to the hospital and patients undergoing thrombolysis. Patients meeting the inclusion and exclusion criteria were identified from the hospital information system and the ward admission register and by manual examination of the patients' case notes. Relevant data were obtained from the case notes and collected on a google form and downloaded in Microsoft Excel 2019. SPSS version 22 was used for data analysis. Results: Out of the 106 patients, 54% (n = 57) were diagnosed as having ischemic stroke, whereas 46% (n = 49) were diagnosed with hemorrhagic stroke after initial assessment and CT scan. Only 2.8% (n = 3) of the patients presented within 4.5 hours of the onset of symptoms. 43.4% (n = 46) presented between 4.5 and 24 hours from the onset, whereas 53.8% (n = 57) presented more than 24 hours after the onset. Twenty-seven patients had their CT scan performed prior to their presentation at the center. For the remaining 79, the median time from presentation to CT scanning was 2 ± 1.5 hours. 24.5% (n = 26) of all patients had an MRI performed in addition to the CT scan. There was wide variation in the time from CT scanning to the MRI. Among the patients who had an MRI, additional information was obtained by the investigation in 58% (n = 15). However, this led to a change in management in only three (11.5%) of the patients. On review, it was found that the change was justified in only two patients. Furthermore, one patient who was diagnosed with tuberculoma had a long history of fever which was missed on initial evaluation. Considering these, MRI can be credited for a meaningful change in management in only 4% (n = 1) of the cases. Conclusion: The findings of this study do not support the routine use of MRI in patients who are not candidates for reperfusion therapy. Their use should be restricted to cases where some specific information is sought or where there is diagnostic uncertainty. Allocation of resources in developing integrated acute stroke pathways is likely to give a better value for money.

Melioidosis in Bihar, India: unearthing the first of many?

Melioidosis, a disease with protean clinical manifestations, is prevalent in many parts of India, with established endemic hotspots on the southern coast of the country. However, it is still underdiagnosed in many resource-poor regions of the country. We report what is, to the best of our knowledge, the first case of melioidosis diagnosed and treated in Bihar, an economically underdeveloped state in East India. The patient, a 52-year-old diabetic male, presented to the outpatient department with a fever of insidious onset along with pain and restriction of movement in the right shoulder joint and right knee joint, and swelling and tenderness of bilateral ankle joints. Radiological features were suggestive of multiple joint and organ abscesses. A diagnosis of disseminated septicaemic melioidosis was confirmed microbiologically. The patient improved clinically following aggressive treatment with meropenem and cotrimoxazole. The case highlights the need for increased clinical suspicion of melioidosis and adequate diagnostic facilities, as well as the need for early institution of appropriate empirical antibiotics in suspected cases of melioidosis in this region of the world.

Radiological difference between new sputum-positive and sputum-negative pulmonary tuberculosis.

INTRODUCTION: The current guidelines for the diagnosis of pulmonary tuberculosis (PTB) are based primarily on the demonstration of acid-fast bacilli (AFB) on sputum microscopy and chest radiograph. Knowing various radiological manifestations and their association with sputum microscopy findings can allow for early diagnosis and early initiation of treatment. AIMS: This study was performed to compare the chest radiograph features seen in sputum-positive and sputum-negative tuberculosis patients, respectively. MATERIALS AND METHODS: It was a prospective observational study, which included 147 consecutive patients newly diagnosed and treated as PTB between Jan 2018 and July 2018. Chest X-ray was reviewed by 2 independent radiologists and the findings were compared between sputum-positive and sputum-negative PTB cases. The obtained data were analyzed by statistics using SPSS version 15 for Windows (SPSS Inc., Chicago, IL) and χ2 test and Student t test were used for statistical analysis. P values < 0.05 were considered statistically significant. RESULTS: Out of a total of 147 patients, 38 (25 males and 13 females, mean age 35.23 ± 18.40) were sputum positive and 109 (77 males and 32 females, mean age 36.07 ± 18.15) were sputum negative. The frequency of patchy consolidation (78.94% vs 49.54%) and cavitation (36.84% vs 15.59%) was significantly higher in sputum-positive PTB (P < 0.05). Radiological lesions like nodular shadow (10.09% vs 2.63%), cystic lesion (13.76% vs 5.26%), fibrosis (12.84% vs 7.89%), miliary shadows (2.75% vs 2.63%), and pleural effusion (1.83% vs 0%) were seen more commonly with sputum-negative PTB but the difference was not statistically significant for any of these features. Sputum-positive PTB tends to occur more commonly on the left side (47.36%) compared with sputum-negative PTB (27.52%) (P < 0.05). 34.21% and 35.77% of the chest X-ray lesions were bilateral in sputum-positive and sputum-negative PTB, respectively. CONCLUSION: Patchy infiltration and cavitation on chest X-ray are seen more frequently in sputum-positive cases of PTB compared with sputum-negative cases.

Cardiac tamponade: atypical presentations after cardiac surgery.

We present two cases of cardiac tamponade presenting in the aftermath of cardiac surgery. We have briefly discussed the aetiology, presentation, diagnosis and management of the condition with emphasis on its atypical presentation in postoperative patients. A high index of suspicion and early access to echocardiography is necessary for prompt recognition and treatment of this life threatening emergency.
