Semiotics of ICU Physicians' Views on End-of-life Care and Quality of Dying in a Critical Care Setting: A Qualitative Study.

Background and aim: While intensive care unit (ICU) mortality rates in India are higher when compared to countries with more resources, fewer patients with clinically futile conditions are subjected to limitation of life-sustaining treatments or given access to palliative care. Although a few surveys and audits have been conducted exploring this phenomenon, the qualitative perspectives of ICU physicians regarding end-of-life care (EOLC) and the quality of dying are yet to be explored. Methods: There are 22 eligible consultant-level ICU physicians working in multidisciplinary ICUs were purposively recruited and interviewed. The study data was analyzed using reflexive thematic analysis (RTA) with a critical realist perspective, and the study findings were interpreted using the lens of the semiotic theory that facilitated the development of themes. Results: About four themes were generated. Intensive care unit physicians perceived the quality of dying as respecting patients' and families' choices, fulfilling their needs, providing continued care beyond death, and ensuring family satisfaction. To achieve this, the EOLC process must encompass timely decision-making, communication, treatment guidelines, visitation rights, and trust-building. The contextual challenges were legal concerns, decision-making complexities, cost-related issues, and managing expectations. To improve care, ICU physicians suggested amplifying patient and family voices, building therapeutic relationships, mitigating conflicts, enhancing palliative care services, and training ICU providers in EOLC. Conclusion: Effective management of critically ill patients with life-limiting illnesses in ICUs requires a holistic approach that considers the complex interplay between the EOLC process, its desired outcome, the quality of dying, care context, and the process of meaning-making by ICU physicians.

Late Onset Hypercalcemia in an HIV Patient as a Manifestation of Immune Reconstitution Inflammatory Syndrome (IRIS).

Hypercalcemia in human immunodeficiency virus (HIV) patients can be challenging due to various underlying mechanisms. 1,25- dihydroxycholecalciferol (1,25 (OH)2 vitamin D)-mediated hypercalcemia due to increased activity of extrarenal 1-alpha hydroxylase is one of the well-known mechanisms of hypercalcemia described in HIV patients. Mycobacterium avium-intracellulare (MAI) is a granulomatous disease that can cause hypercalcemia due to ectopic production of alpha -1 hydroxylase and result in increased levels of 1,25 (OH)2 vitamin D. Herein, we present a case of "late-onset" hypercalcemia in a patient with HIV/AIDS and MAI infection in the setting of suspected immune reconstitution inflammatory syndrome (IRIS). The hypercalcemia workup showed an inappropriately average level of 1,25 (OH)2 vitamin D while the rest of the workup was unrevealing. Unusually normal levels of vitamin D metabolites were the driving mechanism of hypercalcemia in this case. The late presentation of hypercalcemia was likely due to IRIS unmasking an underlying granulomatous infection, and this consideration led to the successful treatment of the patient with steroid administration. This case emphasizes the importance of considering IRIS in evaluating hypercalcemia that presents late in the course of granulomatous infections in HIV patients.

A Prospective Observational Study Comparing Oxygen Saturation/Fraction of Inspired Oxygen Ratio with Partial Pressure of Oxygen in Arterial Blood/Fraction of Inspired Oxygen Ratio among Critically Ill Patients Requiring Different Modes of Oxygen Supplementation in Intensive Care Unit.

Background: Intensive care unit (ICU) patients face a significant rise in mortality rates due to acute hypoxemic respiratory failure (AHRF). The diagnosis of AHRF is based on the PF ratio, but it has limitations in resource-constrained settings. Instead, the Kigali modification suggests using the oxygen saturation/fraction of inspired oxygen (SF) ratio. This study aims to correlate SF ratio and arterial oxygen pressure (PF) ratio in critically ill adults with hypoxemic respiratory failure, who required O2 therapy through different modes of oxygen supplementation. Materials and methods: In an ICU, a prospective observational study included 125 adult AHRF patients receiving oxygen therapy, with data collected on FiO2, PaO2, and SpO2. The SF ratio and PF ratio were calculated, and their correlation was assessed using statistical analysis. The receiver operator characteristics (ROC) curve analysis was conducted to assess the diagnostic precision of the SF ratio in identifying AHRF. Results: Data from a total of 250 samples were collected. The study showed a positive correlation (r = 0.622) between the SF ratio and the PF ratio. The SF threshold values of 252 and 321 were established for PF values of 200 and 300, respectively, featuring a sensitivity of 69% and specificity of 95%. Furthermore, it is worth noting that the PF ratio and SF ratio are interchangeable, regardless of the type of oxygen therapy, as the median values of both the PF ratio and SF ratio displayed statistical significance (p < 0.01) in both acidosis and alkalosis conditions. Conclusion: For patients with AHRF, the noninvasive SF ratio can effectively serve as a substitute for the invasive PF ratio across all oxygen supplementation modes.

Correlation of Quality Metrics of Acute Stroke Care with Clinical Outcomes in an Indian Tertiary-care University Hospital: A Prospective Evidence-based Study.

Aim: To characterize the impact of adherence to quality metrics of stroke care on the clinical outcomes of ischemic stroke (IS) and intracerebral hemorrhage (ICH) admissions. Methods: Consecutive patients with acute stroke were prospectively followed up for their demographic and clinical characteristics, acute stroke management, and associated clinical outcomes at discharge. Stroke quality metrics [adopted from the American Heart Association (AHA)/American Stroke Association's Get with The Guidelines (GWTG)] with a specific interest in an association between acute reperfusion therapies and functional recovery in stroke patients are analyzed and presented. A composite measure of care was considered "0 (non-adherence) to 1 (adherence)." An all-or-none measure of care was calculated to check whether eligible patients received all the quality-of-care interventions. Multivariate Cox regression models were used to study an association between optimal adherence and clinical outcomes. Results: During the study period, of the total 256 stroke admissions, 200 (78.1%) patients had IS, and the remaining 56 (21.9%) patients had ICH. The median [interquartile range (IQR)] age of total stroke admissions was 57 (36-78) years. Male preponderance was observed (IS: 80% and ICH: 67.9%). The conformity of performance metrics in IS patients was from 69.1% [95% confidence interval (CI), 68.5-69.6] for the use of deep vein thrombosis prophylaxis (DVTp) to 97.8% (95% CI, 96.2-98.6) for the use of statins. In ICH patients, it ranged from 61.7% (95% CI, 60.4-62.5) for the use of DVTp to 89.9% (95% CI, 88.6-89.7) for stroke rehabilitation. The unadjusted odds ratio (OR) of mortality (in-hospital plus the 28th-day postdischarge) was higher in ICH patients vs IS patients (4.42, p = 0.005). Optimal adherence with intravenous recombinant tissue plasminogen activator (IV-rtPA) therapy [hazards ratio (HR) = 0.23], in-hospital acute measures [IS (HR = 0.41) and ICH (HR = 0.63)], and discharge measures [IS (HR = 0.35) and ICH (HR = 0.45)] were associated with reduced hazards of the 28th-day mortality in both cohorts. Compared to ICH, IS patients had significantly improved neurofunctional recovery [modified Rankin score (mRS) ≤ 2, p < 0.01]. Conclusion: Adherence to quality metrics and performance measures was associated with low mortality and favorable clinical outcomes. Also, DVTp as an in-hospital (acute) measure of stroke care needs attention in both cerebrovascular events. How to cite this article: Panda BK, Suryawanshi VR, Attarde G, Borkar N, Iyer S, Shah J.

Advances in AI-Driven Retention Prediction for Different Chromatographic Techniques: Unraveling the Complexity.

Retention prediction through Artificial intelligence (AI)-based techniques has gained exponential growth due to their abilities to process complex sets of data and ease the crucial task of identification and separation of compounds in most employed chromatographic techniques. Numerous approaches were reported for retention prediction in different chromatographic techniques, and consistent results demonstrated that the accuracy and effectiveness of deep learning models outclassed the linear machine learning models, mainly in liquid and gas chromatography, as ML algorithms use fewer complex data to train and predict information. Support Vector machine-based neural networks were found to be most utilized for the prediction of retention factors of different compounds in thin-layer chromatography. Cheminformatics, chemometrics, and hybrid approaches were also employed for the modeling and were more reliable in retention prediction over conventional models. Quantitative Structure Retention Relationship (QSRR) was also a potential method for predicting retention in different chromatographic techniques and determining the separation method for analytes. These techniques demonstrated the aids of incorporating QSRR with AI-driven techniques acquiring more precise retention predictions. This review aims at recent exploration of different AI-driven approaches employed for retention prediction in different chromatographic techniques, and due to the lack of summarized literature, it also aims at providing a comprehensive literature that will be highly useful for the society of scientists exploring the field of AI in analytical chemistry.

Incidence and Severity of Adverse Drug Reactions in Medical Intensive Care Unit.

BACKGROUND: Adverse drug reactions (ADRs) curtail patients' quality of life by virtue of increasing therapeutic complexity and rising multimorbidity. In India, the frequency of ADRs for individual drugs and their economic burdens are rarely evaluated. This study aimed at identifying the incidence and severity of ADRs leading to hospitalization (ADRA) and occurring during a hospital stay (ADRH). OBJECTIVE: The objective of this study is to study the incidence and severity of ADRs in the ICU and their impact on the duration of hospitalization, along with the cost incurred to treat ADRs in the ICU. METHOD: Demographic, clinical, and pharmacological data on patients admitted to the ICU were collected, analyzed and evaluated for ADRs. According to the setting analyzed, a descriptive analysis of the reactions, suspected medicines, and associated factors was undertaken. RESULT: A total of 208 patients were admitted to the ICU during the study period, of which ADRA contributed 9.1% of the incidence rate and 8.1% of ADRH in 36 patients. Males had a higher incidence of ADRs than females. Patients who had ADRs had a substantially longer length of stay than those who did not. Electrolyte disturbance was the most commonly found ADR. According to the Hartwig scale and WHO-causality scale, 88.9% were moderate, and 97.2% were possible ADRs, respectively. CONCLUSION: In this study, a similar incidence rate of ADRA and ADRH was observed. The average cost for treating ADRA was higher than that for treating ADRH. As a result, identifying and preventing these reactions is critical, as they cause the patient greater suffering.

Triptan-induced takotsubo syndrome: a case report.

Background: Takotsubo syndrome (TS) is a clinical condition mimicking acute coronary syndrome characterized by reversible acute systolic dysfunction. TS is typically associated with a catecholaminergic surge resulting from physical or emotional stress while some pharmacologic agents may act as a trigger. Case summary: Here, we report a case of TS secondary to rizatriptan, used for treatment of acute migraine. A 67-year-old woman with a history of dyslipidemia, type II diabetes, and migraine was admitted with chest heaviness shortly after taking rizatriptan for migraine. Deepening T wave inversion was seen in multiple territories on electrocardiogram and hs-troponin T was elevated. Cardiac imaging including echocardiogram coronary angiography and cardiac magnetic resonance imaging was consistent with a diagnosis of TS. Discussion: In this case, there was no emotional trigger for TS described. Given the compelling temporal correlation between the onset of typical chest pain and medication use, a diagnosis of TS secondary to rizatriptan was made.

Comparison of admission GCS score to admission GCS-P and FOUR scores for prediction of outcomes among patients with traumatic brain injury in the intensive care unit in India.

BACKGROUND: This study aimed to determine the predictive power of the Full Outline of Unresponsiveness (FOUR) score and the Glasgow Coma Scale Pupil (GCS-P) score in determining outcomes for traumatic brain injury (TBI) patients. The Glasgow Outcome Scale (GOS) was used to evaluate patients at 1 month and 6 months after the injury. METHODS: We conducted a 15-month prospective observational study. It included 50 TBI patients admitted to the ICU who met our inclusion criteria. We used Pearson's correlation coefficient to relate coma scales and outcome measures. The predictive value of these scales was determined using the receiver operating characteristic (ROC) curve, calculating the area under the curve with a 99% confidence interval. All hypotheses were two-tailed, and significance was defined as P<0.01. RESULTS: In the present study, the GCS-P and FOUR scores among all patients on admission as well as in the subset of patients who were mechanically ventilated were statistically significant and strongly correlated with patient outcomes. The correlation coefficient of the GCS score compared to GCS-P and FOUR scores was higher and statistically significant. The areas under the ROC curve for the GCS, GCS-P, and FOUR scores and the number of computed tomography abnormalities were 0.912, 0.905, 0.937, and 0.324, respectively. CONCLUSIONS: The GCS, GCS-P, and FOUR scores are all excellent predictors with a strong positive linear correlation with final outcome prediction. In particular, the GCS score has the best correlation with final outcome.

Current trends in chromatographic prediction using artificial intelligence and machine learning.

Artificial intelligence (AI) and machine learning (ML) gained tremendous growth and are rapidly becoming popular in various fields of prediction due to their potential abilities, accuracy, and speed. Machine learning algorithms employ historical data to analyze or predict information using patterns or trends. AI and ML were most employed in chromatographic predictions and particularly attractive options for liquid chromatography method development, as they can help achieve desired results faster, more accurately, and more efficiently. This review aims at exploring various AI and ML models employed in the determination of chromatographic characteristics. This review also aims to provide deep insight into reported artificial neural network (ANN) associated techniques which maintained better accuracy and significant possibilities for chromatographic characteristics prediction in liquid chromatography over classical linear models and also emphasizes the integration of a fuzzy system with an ANN, as this integrated study provides more efficient and accurate methods in chromatographic prediction than other linear models. This study also focuses on the retention prediction of a target molecule employing QSRR methodology combined with an ANN, highlighting a more effective technique than the QSRR alone. This approach showed the benefits of combining AI or ML algorithms with the QSRR to obtain more accurate retention predictions, emphasizing the potential of artificial intelligence and machine learning for overcoming adversities in analytical chemistry.

Wunderlich Syndrome: Comprehensive Review of Diagnosis and Management.

Wunderlich syndrome (WS), which was named after Carl Wunderlich, is a rare clinical syndrome characterized by an acute onset of spontaneous renal hemorrhage into the subcapsular, perirenal, and/or pararenal spaces, without a history of antecedent trauma. Patients may present with a multitude of symptoms ranging from nonspecific flank or abdominal pain to serious manifestations such as hypovolemic shock. The classic symptom complex of flank pain, a flank mass, and hypovolemic shock referred to as the Lenk triad is seen in a small subset of patients. Renal neoplasms such as angiomyolipomas and clear cell renal cell carcinomas that display an increased proclivity for hemorrhage and rupture contribute to approximately 60%-65% of all cases of WS. A plethora of renal vascular diseases (aneurysms or pseudoaneurysms, arteriovenous malformations or fistulae, renal vein thrombosis, and vasculitis syndromes) account for 20%-30% of cases of WS. Rare causes of WS include renal infections, cystic diseases, calculi, kidney failure, and coagulation disorders. Cross-sectional imaging modalities, particularly multiphasic CT or MRI, are integral to the detection, localization, and characterization of the underlying causes and facilitate optimal management. However, large-volume hemorrhage at patient presentation may obscure underlying causes, particularly neoplasms. If the initial CT or MRI examination shows no contributary causes, a dedicated CT or MRI follow-up study may be warranted to establish the cause of WS. Renal arterial embolization is a useful, minimally invasive, therapeutic option in patients who present with acute or life-threatening hemorrhage and can help avoid emergency radical surgery. Accurate diagnosis of the underlying cause of WS is critical for optimal patient treatment in emergency and nonemergency clinical settings. ©RSNA, 2023 Quiz questions for this article are available through the Online Learning Center.

Endotracheal Intubation with King Vision Video Laryngoscope vs Macintosh Direct Laryngoscope in ICU: A Comparative Evaluation of Performance and Outcomes.

Background: Endotracheal intubation to protect airway patency in critically ill patients with the use of videolaryngoscopes has been emerging and their expertise to handle is crucial. Our study focuses on the performance and outcomes of King Vision video laryngoscope (KVVL) in intensive care unit (ICU) compared to Macintosh direct laryngoscope (DL). Materials and methods: This comparative study was conducted by randomizing 143 critically ill patients in ICU into two groups: KVVL and Macintosh DL (n = 73; n = 70). The intubation difficulty was assessed by Mallampati score III or IV, apnea syndrome (obstructive), cervical spine limitation, opening mouth <3 cm, coma, hypoxia, anesthesiologist nontrained (MACOCHA) score. The primary endpoint was the glottic view measured by Cormack-Lehane (CL) grading. The secondary endpoints were a first-pass success, the time required for intubation, airway morbidities, and manipulations required. Results: The KVVL group showed the primary endpoint of significantly improved glottic visualization measured in terms of CL grading compared with the Macintosh DL group (p < 0.001). In the KVVL group, the first pass success rate was higher (95.7%) compared to the Macintosh DL group (81.4%) (p < 0.05). The time required for intubation in the KVVL group (28.77 ± 2.63 seconds) was significantly less compared with Macintosh DL (38.84 ± 2.72 seconds) group (p < 0.001). The airway morbidities observed were similar in both groups (p = 0.5) and the manipulation required for endotracheal intubation was significantly less (p < 0.05) in our KVVL group (16 cases; 23%) compared to the Macintosh DL group (8 cases; 10%). Conclusion: We found that the performance and outcomes of KVVL in intubating critically ill ICU patients were promising when handled by experienced operators who are experts in anesthesiology and airway management.

Radical prostatectomy readmissions: Causes, risk factors, national rates, & costs.

INTRODUCTION: Readmissions have substantial clinical and financial impacts on the healthcare system. Radical prostatectomy (RP) is considered a standard treatment in the management of clinically localized prostate cancer. Yet, there is a paucity of research evaluating readmissions for RP in a national dataset. PATIENTS AND METHODS: Patients with histologically confirmed prostate cancer managed with RP were identified within the 2016 to 2018 Nationwide Readmissions Database. Patient factors, facility factors, and surgical characteristics were evaluated for associations with readmission using univariable and multivariable analyses. RESULTS: A total of 133,727 patients receiving RP were identified. Early (30-day) and late (31-90-day) readmission rates were 4.2% and 1.8% respectively. The most common cause of early readmission was postoperative digestive system complication (10%) and the most common cause of late readmission was septicemia (13%). On multivariable logistic regression, factors associated with both early and late readmission include nonroutine discharge at index (early: OR 1.877, 95% CI 1.667-2.113; late: OR 1.801, 95% CI 1.490-2.183), and circulatory system comorbidity (early: OR 1.29, 95% CI 1.082-1.538); late: OR 1.515, 95% CI 1.157-1.984). CONCLUSIONS: Our findings regarding factors associated with readmission provide insight for RP counseling and may inform postoperative care pathways. Elucidation of readmission trends may allow the identification and proactive management of patients at higher risk for readmission.

Adult Wilms tumor: An unusual case report with dedicated literature review.

Wilms tumor is the most common primary renal malignancy in pediatric age group, however, is rare in adults accounting for 0.5% of all adult renal malignancies. The histopathology is similar in both age groups, however the prognosis in adults is poor with tumor being at advanced stage at presentation with increased incidence of metastasis. Due to rare occurrence in adults and lack of differentiating clinical and imaging features its diagnosis is delayed or often misdiagnosed as adult renal cell cancer. Pre surgical or early post-surgical chemotherapy has shown significantly better surgical outcome and survival rate, however, delayed or misdiagnosis precludes or delays the chemotherapy. Lack of standardized treatment guidelines for adults also adds to the poor prognosis. Presurgical biopsy of renal masses in young adults can be suggested for early diagnosis as well as inclusion of presurgical chemotherapy for overall better outcome.

Gastrointestinal duplication cysts: what a radiologist needs to know.

Gastrointestinal tract duplication cysts are rare congenital malformations which can be diagnosed as early as the prenatal period but are frequently found in infancy or incidentally in adulthood. They can be seen throughout the alimentary tract with the most common involving the distal ileum and second most common the esophagus. Many duplication cysts are asymptomatic and thus discovered as an incidental imaging finding, though they can also be symptomatic with an array of clinical presentations dependent largely on their location. The vast majority of duplication cysts are benign; however, there are rare instances of malignant transformation reported. The aim of this review is to show how multimodality imaging can help in the diagnosis of duplication cysts at various anatomical locations. Duplication cyst can become symptomatic and in rare cases undergo malignant transformation; therefore, they are typically managed with surgical excision, particularly if found prenatally or during infancy. Given the diversity of anatomic locations, multiple differential diagnoses, and the need for surgical intervention, it is valuable to comprehend the role of multimodality imaging role in diagnosing duplication cysts.

Noninvasive Respiratory Assist Devices in the Management of COVID-19-related Hypoxic Respiratory Failure: Pune ISCCM COVID-19 ARDS Study Consortium (PICASo).

Objective: To determine whether high-flow nasal oxygen (HFNO) or noninvasive ventilator (NIV) can avoid invasive mechanical ventilation (IMV) in COVID-19-related acute respiratory distress syndrome (ADRS), and the outcome predictors of these modalities. Design: Multicenter retrospective study conducted in 12 ICUs in Pune, India. Patients: Patients with COVID-19 pneumonia who had PaO2/FiO2 ratio <150 and were treated with HFNO and/or NIV. Intervention: HFNO and/or NIV. Measurements: The primary outcome was to assess the need of IMV. Secondary outcomes were death at Day 28 and mortality rates in different treatment groups. Main results: Among 1,201 patients who met the inclusion criteria, 35.9% (431/1,201) were treated successfully with HFNO and/or NIV and did not require IMV. About 59.5% (714/1,201) patients needed IMV for the failure of HFNO and/or NIV. About 48.3, 61.6, and 63.6% of patients who were treated with HFNO, NIV, or both, respectively, needed IMV. The need of IMV was significantly lower in the HFNO group (p <0.001). The 28-day mortality was 44.9, 59.9, and 59.6% in the patients treated with HFNO, NIV, or both, respectively (p <0.001). On multivariate regression analysis, presence of any comorbidity, SpO2 <90%, and presence of nonrespiratory organ dysfunction were independent and significant determinants of mortality (p <0.05). Conclusions: During COVID-19 pandemic surge, HFNO and/or NIV could successfully avoid IMV in 35.5% individuals with PO2/FiO2 ratio <150. Those who needed IMV due to failure of HFNO or NIV had high (87.5%) mortality. How to cite this article: Jog S, Zirpe K, Dixit S, Godavarthy P, Shahane M, Kadapatti K, et al.

Direct Medical Cost Analysis of Indian COVID-19 Patients Requiring Critical Care Admission.

INTRODUCTION: Intensive care unit (ICU) admission is required for approximately 25% of patients affected with coronavirus disease-19 (COVID-19) and imposes a high economic burden on patients in resource-limited settings. METHOD: We conducted a retrospective direct medical care cost analysis of COVID-19 patients requiring ICU admission after obtaining the Institutional Ethics Committee approval. Data were obtained from the records of patients admitted to the COVID-19 ICU of a tertiary care trust teaching hospital from June 2020 to December 2020. Direct costs were analyzed and correlated with various demographic variables and clinical outcomes. RESULTS: A total of 176 patients were included (males-76%). The median direct medical cost for a median stay of 13 days was INR 202248.5 ($ 2742.91). Hospital drugs and disposables accounted for 20% of the total cost followed by bed charges (19%), equipment charges (17%), biosafety protective gear (15.5%), pathological and radiological tests (15%), clinical management (7.6%), and biomedical waste management (1.6%). Government schemes accounted for 79% of medical claims followed by directly paying patients (12.5%) and private insurance (8.5%). The cost was significantly higher in patients with diabetes mellitus and sepsis and in those requiring mechanical ventilation (MV) (p <0.05). Shorter lead time to hospital admission and lesser length of hospital stay were associated with significant lower direct cost. CONCLUSION: Direct medical care cost is substantial for COVID-19 patients requiring ICU admission. This cost is significantly associated with increased ICU and hospital stay, longer lead time to admission, diabetes mellitus, sepsis, and those who need high-flow nasal cannula (HFNC), noninvasive ventilation (NIV), and MV.

Off-label Drug Prescription Pattern and Related Adverse Drug Reactions in the Medical Intensive Care Unit.

Introduction: The utilization of prescription drugs as off-label is common. While this practice can be beneficial to some patients, it can raise a safety concern when scientific evidence is lacking; hence, this study was conducted to evaluate the off-label drug consumption and its adverse drug reactions (ADRs) in the medical intensive care unit (ICU). Materials and methods: In the prospective cohort study conducted for a duration of 6 months, data pertaining to ICU patients' (age ≥18 years) demography, diagnosis, treatment, and laboratory investigation were collected to assess for off-label use as well as the strength of evidence and the occurrence of ADRs by using MICROMEDEX 2017 version (Healthcare Series Thomson Reuter, Greenwood, CO). Results: Of total 3574 drugs prescribed, 1453 (41%) were off-label indications and 65 (1.81%) were off-label dose. On the evaluation of off-label indication use, 1279 (88%) were evidence-based and 174 (12%) were low/no evidence-based medications (EBMs); 59 (91%) were evidence-based and 6 (9%) were low/no EBMs for off-label dose. Most commonly prescribed evidence-based off-label drug belonged to the gastrointestinal class while low/no evidence drugs were mostly of anti-infective class. A total of 383 ADRs were identified and 139 (36.2%) were implicated due to off-label medications, of which ADRs with evidence off-label medications (87.8%) were higher than low/no evidence off-label medication (12.2%) (P < 0.001). Conclusion: Widespread presence of off-label use was observed in medical ICU. Although incidence of ADRs was similar to the FDA-approved use, ongoing monitoring of such practice is needed.

Stress Level and Its Determinants among Staff (Doctors and Nurses) Working in the Critical Care Unit.

Background: Very few extensive studies regarding job stressors among doctors and nurses have been conducted in India. It is important to explore the workplace to understand various stressors that adversely affect the well-being of an individual and also affect health care and needs of patients and relatives. Considering this, the present study was planned to determine stress among doctors and nurses from the critical care unit (CCU) and to find the association of stress with selected variables. Materials and methods: This observational cross-sectional study was conducted among all staff (doctors and nurses) from the CCU. Data were collected with a pilot-tested, predesigned, validated questionnaire using the Google survey tool consisting of sociodemographic details and the ICMR work stress questionnaire. Analysis of data was done with SPSS version 25. Results: Of 105 participants, 57 (54.3%) were doctors and 48 (45.7%) were nurses. A total of 48.6% (51) of participants scored 32 of 64, that is, managed stress very well, and 51.4% of participants (54) scored 65 of 95, that is, having a reasonably safe level of stress, but certain areas need improvement. Conclusion: Stress was significantly more among females and those who have sleep problems. No statistically significant difference was found between the level of stress and age, relationship with seniors, exercise, and comorbidities.
