Context: Six Sigma methodology represents an evolution in quality assessment and management that has been implemented widely in industry and health sector since the mid-1980s. It consists of five steps: define, measure, analyze, improve, and control (DMAIC). Randox International Quality Assessment Scheme (RIQAS) program Target Score (TS) is a performance indicator, and Sigma metrics is considered as a gold standard for overall performance. Aim: The aim of this study is to present the TS and Sigma metrics observed in clinical chemistry laboratory in SSK Hospital associated with Lady Hardinge Medical College to evaluate the analytical performance of T3, T4, and thyroid-stimulating hormone (TSH) parameters. The study period is from June to August 2022. Materials and Methods: The Sigma metrics for the various analytes was calculated by the following equation: Σ = TEa − bias/CV (TEa—total allowable error, CV—coefficient of variation). Acceptable performance criteria: standard deviation index (SDI) <2; TS >50; the closer a value is to 120, the better the performance, <40 is unacceptable; and %deviation should be less than the defined acceptable limits which is unique to each analyte, the closer the value is to zero, the better is the performance. Results: Our RIQAS results lie in acceptable range except for T3 in the month of August in which TS was unacceptable. Our laboratory Sigma metrics were below three sigmas. The findings of our exercise emphasize the need for a detailed evaluation, and we promote the use of Sigma metrics in quality assurance in the best interest of the patient. Conclusion: Quality check strategies were applied according to the TS and sigma values.
Background: Timely preparation and presentation of the annual cumulative antibiogram play an important role in the dissemination of an updated susceptibility pattern to clinicians and thus aid in the appropriate choice of antimicrobials for empirical therapy while minimizing adverse effects and resistance. The study aimed to present and analyze the annual AMR data that may be helpful in designing antibiotic policy. Methods: All clinical specimens routinely submitted to the Department of Microbiology from January to December 2021 for bacteriological culture and antimicrobial susceptibility testing (AST) were included. AST was performed for pathogenic isolates by disc diffusion/agar dilution/broth microdilution methods/VITEK® 2 compact system. All data were entered and analyzed using WHONET 2020 software. Results: A total of 46,629 routine specimens were processed, yielding 5792 non-repeat bacterial isolates. Relatively fewer specimens were received during the first few months when the hospital catered exclusively to COVID-19 patients. The most common bacterial isolates were Escherichiacoli (30%), Staphylococcus aureus (21%), Klebsiella sp. (18%), Pseudomonas sp. (10%), Acinetobacter sp. (8%) and Enterococcus sp. (5%). Analysis showed low susceptibility to 3rd generation cephalosporins, fluroquinolones, and cotrimoxazole among Gram negative bacteria. Less than 50% Acinetobacter sp. were carbapenem susceptible. We report high rate of methicillin resistance in S. aureus (74%). Overall susceptibility was much lower in specimens from ICU followed by in-patients and out-patients. Conclusion: Antimicrobial resistance is rapidly assuming the proportions of a pandemic, with several authors calling it "invisible" pandemic. As is evident from the present study, low susceptibilities to all but a few last-resort drugs are leaving few choices for treatment. This mandates effective preparation, distribution, and presentation of annual antibiograms, which will help in formulating hospital antibiotic policy.
Background: An intravenous infusion of lidocaine has been used on numerous occasions to produce analgesia in neuropathic pain. It has been shown to be beneficial for the treatment of variety of neuropathic pain states in a wide range of dosage, from 2 to 7.5 mg/kg. The aim of our study was to evaluate the efficacy of two different doses of intravenous lidocaine (3 and 4 mg/kg) in patients with chronic pain. Methods: Patients above the age of 18 years suffering from chronic pain due to postherpetic neuralgia, post-surgical scar pain, chronic low back pain having numeric analogue scale (NAS) pain score of ≥3 without satisfactory pain relief from conservative treatment were randomised to receive either 3 mg/kg or 4 mg/kg intravenous lidocaine in 250 mL normal saline infusions weekly over a period of 1 hour for 3 weeks. NAS was measured before starting each infusion, immediately after completion of infusion, 2 and 24 hours, 7th day, 14th day, 21st day, and 28th day. Results: NAS score at first hour and 24th hour was significantly reduced (P = 0.001), after each infusion [7th, 14th day] in both the groups. There was no statistical difference in pain score among both groups except for day 7 (P value 0.04). Reduction in NAS score was also present on 21st and 28th day in both groups, but it did not reach a significant value. On 28th day, NAS score values showed increasing trend. Duration of pain relief was around 1 week after each infusion in both groups. Conclusion: Intravenous lidocaine at a dose of 3 mg/kg or 4 mg/kg was effective in reducing pain in patients with chronic pain. The analgesic effect was not different among both groups. Trend of greater response was observed with 4 mg/kg dose.
Gadolinium-based magnetic resonance imaging (MRI) contrast is considered stable and safe compared to iodine-based contrast agents; however, unseen and unexpected complications may occur at any time. We present the case of a 45-year-old patient who was posted for MRI contrast of the abdomen. After a few minutes of contrast injection, the patient was found having shortness of breath, chest pain with nausea, and vomiting. Pulmonary auscultation revealed bilateral fine crepitations, but he did not develop rash or angioedema and was immediately managed with steroids and with supplemental oxygen support. However, he started desaturating and shifted to the nearby emergency department where high-resolution computed tomography (HRCT) was done and showed ground-glass opacities. Coronavirus disease (COVID) swab test was negative and the patient was shifted to intensive care unit (ICU) with the provisional diagnosis of developing acute respiratory distress syndrome (ARDS). He was managed conservatively on bilevel positive airway pressure (BiPAP) and discharged after 10 days with full recovery. There is no specific biomarker for ARDS triggered by MRI contrast, and the clinical presentation is indistinguishable from other causes. Gadolinium contrast-induced ARDS is a rare but potentially life-threatening complication that should be considered in the differential diagnosis of respiratory failure following an MRI contrast injection. It is critical to be aware of this potential complication in order to provide the best outcome for the patient’s management.
Introduction: Nationwide lockdown during COVID-19 pandemic, rapid transmission of SARS-CoV-2 and more intense second wave of pandemic in terms of high caseload, reduced essential supplies and scarcity of beds, and unpredictable mortality had a huge impact on mental health of general population. Objectives: This study aimed to estimate the prevalence and determine the factors of Post-Traumatic Stress Disorder (PTSD) among the general population of India during the second wave of pandemic. Methodology: An online survey was conducted to estimate the prevalence and assess the factors responsible for PTSD among 614 participants who were above 18 years of age. The prevalence of PTSD was measured using PTSD checklist for Diagnostic and Statistical Manual of Mental Disorder-5 (DSM-5). Results: In the present study, there were a total of 614 participants and the mean age of the participants was 23.64 years. More than half of the participants were female and majority of them were unmarried (76.7%). The prevalence of PTSD was 30.62%. A significant association was observed between occupation and PTSD prevalence. Also, COVID-19 illness, COVID-19 infection among the family members, work outside the home, hospital admissions, difficulty in acquiring the required medication were significantly associated with PTSD. Conclusion: COVID-19 pandemic and nationwide lockdown led to increased prevalence of psychological effects like PTSD. This highlights the importance of focusing on mental health during the pandemic.
