RESUMEN
BACKGROUND: Pupillary assessment is an important part of the neurological assessment which provides vital information in critically ill patients. However, clinical pupillary assessment is subjective. The ultrasound-guided pupillary examination is objective. There are limited pieces of literature regarding its use in assessing patients with altered mental status. So, we studied the extent of agreement of B-mode ultrasound with clinical examination for assessment of the pupillary size and reflex in patients with altered mental status. OBJECTIVES: The primary objective was to determine the extent of agreement between clinical examination and ultrasound-based examination for assessing pupillary reflex and size in patients with altered mental status in two settings (trauma and non-trauma patients). METHODS: Exactly 200 subjects (158 males, mean [range] age 43.56 [18-92 years]) with no history of partial globe rupture or dementia were included in this cross-sectional study from March 2019 to March 2020. B-mode ultrasound was performed with the subject's eyes closed using a 7-12 MHz linear probe and a standardized light stimulus. ICC score, paired t-test, kappa, Wilcoxon signed-rank test, and Bland-Altman plots were used for statistical analysis. RESULTS: The clinical-USG agreement for pupillary light reflex examination (Pupillary Diameter [PD] at rest, after direct light stimulation [Dstim ] and consensual light stimulation [Cstim ]) was excellent (ICC, 0.93-0.96). The Kappa coefficient (0.74 ± 0.07) showed an agreement of 87.36% between clinical and USG examination for pupillary reflex (reactive or non-reactive). CONCLUSION: USG-guided pupillary examination proves to be a better adjunct to neurological assessment in patients with altered mental status.

Background: The main objective is to detect clinically significant conditions by transcranial ultrasound (TCS) in post-decompressive craniectomy (DC) patients who come to the emergency department. Materials and methods: This was a cross-sectional observational study. We studied 40 post-DC patients. After primary stabilization, TCS was done. Computer tomography of head was done within 2 hours of performing TCS. The correlation between both modalities were assessed by the measurement of lateral ventricle (LV) (Bland-Altman plot), Midline shift and mass lesion. Additionally, normal cerebral anatomy, 3rd and 4th ventricles and external ventricular drainage (EVD) catheter visualization were also done. Results: About 14/40 patients came with non-neurosurgical complaints and 26/40 patients came with neurosurgical complaints. Patients with non-neurosurgical complaints (4/14) had mass lesions and 1/14 had MLS. Patients with neurosurgical complaints (11/26) had mass lesions and about 5 patients had MLS. A good correlation was found between TCS and CT of head in measuring LV right (CT head = 17.4 ± 13.8 mm and TCS = 17.1 ± 14.8 mm. The mean difference (95% CI) = [0.28 (-1.9 to 1.33), ICC 0.93 (0.88-0.96)], Left [CT head = 17.8 ± 14.4 mm and TCS = 17.1 ± 14.2 mm, the mean difference (95% CI) 0.63 (-1.8 to 0.61), ICC 0.96 (0.93-0.98)], MLS [CT head = 6.16 ± 3.59 (n = 7) and TCS = 7.883 ± 4.17 (n = 6)] and mass lesions (kappa 0.84 [0.72-0.89] [95% CI] p-value < 0.001). The agreement between both modalities for detecting mass lesions is 93.75%. Conclusion: Point of care ultrasound (POCUS) is a bedside, easily operable, non-radiation hazard and dynamic imaging tool that can be used for TCS as a supplement to CT head in post-DC patients in emergency as well as in ICU. However, assessment of the ventricular system (pre/post-EVD insertion), monitoring of regression/progression of mass lesion, etc. can be done with TCS. Repeated scans are possible in less time which can decrease the frequency of CT head. How to cite this article: Chouhan R, Sinha TP, Bhoi S, Kumar A, Agrawal D, Nayer J, et al.

RESUMEN
INTRODUCTION: Point of care ultrasound (POCUS) has variable diagnostic accuracy in diagnosing fractures. Waterbath technique is a modification of the conventional ultrasound technique which may improve diagnostic accuracy by enhancing image quality. Authors studied the diagnostic accuracy of waterbath technique compared to the final diagnosis based on clinical examination and radiology in the identification of fractures of hand and foot. METHODS: Patients of >18 yrs. age with suspected distal hand and foot fractures presenting to the emergency department of a level 1 trauma center were recruited after informed consent. Unconscious and hemodynamically unstable patients, injuries >72 h old, open fractures, obvious deformities, and old fractures at the affected site were excluded. Cases were subjected to waterbath technique performed by an academic emergency medicine resident and relevant radiographs were ordered and interpreted by an orthopedic specialist. CT/MRI, if done in case of discrepancy, was interpreted by radiologist. The findings of both waterbath technique and radiology were blinded to each other and compared to the final diagnosis made by a cumulative assessment of clinical examination, radiographs, and CT/MRI of the discrepant cases. RESULTS: Waterbath technique identified fractures of hand and foot with sensitivity of 97% (95% CI 90%-100%), specificity 94% (95%CI 81%-99%), PPV 98% (95%CI 91%-99%), NPV 94% (95%CI 79%-98%), LR+ 17.5(95% CI 4.5-67.2), LR- 0.03(95% CI 0.01-0.12) and diagnostic accuracy 96% (95%CI 91%-99%). CONCLUSION: This pilot study has demonstrated the utility of Waterbath technique in the diagnosis of fractures of hand and foot in adults in the ED setting. Future well designed studies are required to explore the potential of this novel technique in both adult and pediatric population.

We conducted a prospective, observational study to assess the serum chymase level, a mast cell derived protease, as a predictor of dengue severity. NS1-positive non-severe dengue patients of age ≥14 years with duration of fever ≤4 days were included in the study. At the time of admission, the serum sample was taken for chymase estimation. Patients were followed up to four days after they became afebrile to find out the final diagnosis. Total of 338 non-severe dengue patients were recruited (mean age: 29.15 years; male: 66%). On follow-up, 26 patients (7.8%) developed severe dengue. Only chymase level (adjusted odds ratio [aOR]: 1.787; 95% confidence interval [CI]: 1.309-2.440) and platelet count at admission (aOR: 0.981; 95% CI: 0.968-0.993) were able to predict the severity after adjustment for all variables. But, for prediction of severe dengue, the area under receiver's operating curve of chymase was 0.835 (95% CI: 0.765-0.905), which was significantly higher than that of the platelet count at admission (0.760, 95% CI: 0.650-0.870) (p < .001). Patients who developed severe dengue in due course of illness had significantly higher serum chymase level at admission as compared with the rest of the patients. Similar findings were noted across all age-groups. At an optimum cut-off value of 1.35 ng/ml, chymase had a positive likelihood ratio (LR) of 3.5 and a negative LR of 0.15, for predicting severe dengue. This study demonstrated the potential ability of serum chymase levels at admission, as a biomarker for prediction of severe dengue in due course of illness.

Pericardial effusion is commonly detected in patients with severe hypothyroidism and is typically mild; rarely, it may lead to cardiac tamponade. Cardiac tamponade with myxedema coma as initial presenting feature of previously unrecognized hypothyroidism is rare. This case highlights that previously undiagnosed hypothyroidism can manifest as myxedema coma with shock due to pericardial tamponade particularly in winters because a cold environment can precipitate myxedema.We report an undiagnosed case of primary hypothyroidism who presented to the emergency department for the first time with both cardiac tamponade and myxedema coma. This combination of cardiac tamponade and myxedema coma as the presenting features of primary hypothyroidism has rarely been reported in the literature. The patient was effectively managed with echocardiography-guided pericardiocentesis, levothyroxine, and external rewarming. Cardiac tamponade and myxedema coma as presenting features of previously unrecognized primary hypothyroidism are extremely rare. Urgent bedside echocardiography with pericardiocentesis along with thyroxine therapy is the treatment of choice. It is important to include hypothyroidism as the differential diagnosis in patients with cardiac tamponade and altered level of consciousness especially in winter months.

AIMS: To determine the incidence of central line associated bloodstream infections (CLABSIs) in the medical intensive care unit (ICU) and ward setting at All India Institute of Medical Sciences (AIIMS), New Delhi. SETTINGS AND DESIGN: The study was conducted in the medical ICU, a 9-bedded ICU at the AIIMS, a tertiary care teaching hospital. The study design was a prospective observational study. METHODS: One hundred patients admitted to medical ICU and the ward at AIIMS with an indwelling, non-tunnelled central venous catheter (CVC) in place at admission and those with a hospital stay with indwelling CVC for more than 48 hours were monitored. These patients were followed daily for the development of new onset sepsis 48 hours after insertion of CVC, in which case three sets of blood samples for culture were drawn over a span of 24 hours. STATISTICAL METHODS: Incidence of CLABSIs was measured per 1000 central line days. RESULTS: One hundred patients hospitalised for an aggregate 1119 days acquired 29 hospital-acquired infections (HAIs), a rate of 38.8% or 31.2 HAIs per 1000 hospital days. The incidence of bloodstream infections (BSIs) in this group was 6.8%. No case of laboratory confirmed CLABSIs could be demonstrated. Incidence of clinical sepsis was 27.6% or 8.2 per 1000 CVC days. There were 9 cases out of the 29 patients (39.7%) who had evidence of HAIs with no apparent focus of infection. Only one of these cases had evidence of BSI with isolation of Staphylococcus aureus in both CVC tip culture and the simultaneous blood culture; however the antibiograms were different. CONCLUSIONS: The low rate of BSIs in the present study and the absence of occurrence of a laboratory confirmed CLABSI should be interpreted in the light of the small sample size of the study and the multitude of antibiotics received before the development of HAI.

Introduction: Full outline of unresponsiveness (FOUR) score has advantages over Glasgow Coma Scale (GCS); as it can be used in intubated patients and provides greater neurological details. It has been studied mainly in the trauma and neuroscience setting. Our primary objective was to compare the FOUR versus GCS score as predictors of mortality at 30 days and poor functional outcome at 3 months among nontrauma patients in the emergency department (ED). Methods: This prospective observational study was conducted on adult patients presenting with altered mental status (duration <7 days) in the ED (March 2019-November 2020). Data collection included demographic and clinical features, the GCS and FOUR scores, the feasibility of acquiring and interpreting FOUR on a Likert scale, duration of hospital stay, 30-day mortality, and functional outcome at 3 months on the modified Rankin Scale. Trained emergency medicine residents managing the patient collected the data. The area under receiver's operating characteristics curve (AUROC) was used to compare the accuracy of the GCS and FOUR scores in predicting outcomes. The FOUR score equivalent of GCS cutoffs for categorizing neurological impairment (mild, moderate, and severe) was also investigated. Results: Two hundred and ninety-one patients were included, with a mean age of 50.3 years and 67.4% males. Most patients (40.2%) had altered mental status for 1-3 days and hepatic encephalopathy was the most common ED diagnosis. The mortality at 30 days was 66.7% (194 of 291), and 88% (256 of 291) of patients had poor functional outcomes at 3 months. The AUROCs for predicting 30-day mortality were similar for both the scores (GCS: 0.70, FOUR: 0.71, and the P value for difference: 0.9). Similarly, the AUROCs for predicting 3-month poor functional outcome were 0.683 and 0.669 using GCS and FOUR, respectively, with a nonsignificant difference (P = 0.82). The FOUR score strata of 14-16, 11-13, and 0-10 were found to be equivalent to the GCS scores of 13-15 (mild), 9-12 (moderate), and 3-8 (severe). The feasibility of acquiring and interpreting GCS and FOUR scores on the Likert scale was found to be "easy." Conclusion: The FOUR score is similar to GCS in predicting mortality at 30 days and poor neurological outcomes at 3 months among nontrauma patients of ED. Moreover, it was found that the FOUR score is "easy" to assess and interpret by the emergency residents.
RESUMEN
BACKGROUND: Administration of rifampicin along with nevirapine reduces the plasma concentration of nevirapine in human immunodeficiency virus positive individuals with concomitant tuberculosis (HIV-TB patients). Nevirapine is a much cheaper drug than its alternative efavirenz, and might be beneficial in resource constrained settings. METHODS: A randomised open label trial was conducted at All India Institute of Medical Sciences, New Delhi, India. During the regimen of an antiretroviral therapy (ART), naive HIV-TB patients were randomly assigned to receive either nevirapine or efavirenz based ART with concomitant rifampicin based anti-tubercular therapy (ATT). Participants were followed for 24 months after starting ART. The end points were virological, immunological and clinical responses, and progression of HIV disease marked by failure of ART. RESULTS: Of the 135 HIV-TB patients, who were receiving rifampicin based ATT, 68 were selected randomly to receive efavirenz based ART and 67 to receive nevirapine based ART. The virological failure rates in the overall population, and the nevirapine and efavirenz groups were 14.1% (19/135); 14.9% (10/67) and 13.2% (9/68), respectively (p =0.94). No significant difference was found between the groups in the rate of clinical, immunological or virological failures. The overall mortality was 17% with no significant difference between the two groups. Except for the lead in period on day 14, the mean nevirapine concentration remained above 3 mg/L. No association was found between plasma levels of nevirapine and incidence of unfavourable outcomes in this group. CONCLUSIONS: Outcome of ART in HIV-TB patients on rifampicin based ATT showed no significant difference, irrespective of whether efavirenz or nevirapine was used. Therefore, nevirapine based ART could be an alternative in the resource limited settings in patients with HIV and tuberculosis co-infection. TRIAL REGISTRATION: NCT No. 01805258.

BACKGROUND & OBJECTIVES: HIV/AIDS patients may have renal involvement also, however, Indian data are sparse. The present study was done to find the spectrum of renal diseases in HIV/AIDS patients in north India. METHODS: In this prospective pilot study, HIV positive patients aged >18 yr were screened for renal involvement [serum creatinine >1.5 mg% and/or significant proteinuria (>500 mg /day)]. Patients who were positive on screening were followed up prospectively and underwent kidney biopsy if indicated. RESULTS: A total of 526 patients were screened, of these, 91 (17.3%) were found to have renal involvement. Group A (Treatment naοve) comprised 392 patients who were not on antiretroviral treatment (ART) and group B (patients on ART) comprised 134 patients. More patients (74/392, 18.9%) in group A had renal involvement as compared to patients in group B (17/134, 12.7%). Of the 91 patients with renal involvement, 26 were followed up and underwent kidney biopsy. Thirteen patients had only proteinuria and another 13 had renal dysfunction with or without proteinuria. Most common histological diagnosis was mesangioproliferative glomerulonephritis (mes PGN) (10/26). Two patients had collapsing FSGS (focal segmental glomerulosclerosis) and three patients had immune complex glomerulonephritis. Seven patients had acute kidney injury, whom six totally recovered from their renal function. All patients with mesPGN tolerated angiotensin converting enzyme (ACE) inhibitors well. There was mixed response of collapsing FSGS to steroids. Both patients with MPGN (membranoproliferative glomerulonephritis) did well on low dose of steroid and ART. INTERPRETATION & CONCLUSIONS: Renal involvement was found to be common in HIV positive patients (17.3%). A low occurrence of renal involvement found in patients already on ART suggests some renoprotective effect of ART. Our preliminary results showed that collapsing FSGS was not rare in Indian HIV positive population, but classical HIV associated nephropathy was not seen. Longitudinal studies with robust study design and large sample size need to be done to confirm the findings.

Introduction: Sepsis is the leading cause of mortality, and various scoring systems have been developed for its early identification and treatment. The objective was to test the ability of quick sequential organ failure assessment (qSOFA) score to identify sepsis and predict sepsis-related mortality in the emergency department (ED). Methods: We conducted a prospective study from July 2018 to April 2020. Consecutive patients with age ≥18 years who presented to the ED with a clinical suspicion of infection were included. Sensitivity, specificity, positive predictive value (PPV), negative predictive values (NPV), and odds ratio (OR) for sepsis related mortality on day 7 and 28 were measured. Results: A total of 1200 patients were recruited; of which 48 patients were excluded and 17 patients were lost to follow-up. 54 (45.4%) of 119 patients with positive qSOFA (qSOFA >2) died at 7 days and 76 (63.9%) died at 28 days. A total of 103 (10.1%) of 1016 patients with negative qSOFA (qSOFA score <2) died at 7 days and 207 (20.4%) died at 28 days. Patients with positive qSOFA score were at higher odds of dying at 7 days (OR: 3.9, 95% confidence interval [CI]: 3.1-5.2, P < 0.001) and 28 days (OR: 6.9, 95% CI: 4.6-10.3, P < 0.001). The PPV and NPV with positive qSOFA score to predict 7- and 28-day mortality were 45.4%, 89.9% and 63.9%, 79.6%, respectively. Conclusion: The qSOFA score can be used as a risk stratification tool in a resource-limited setting to identify infected patients at an increased risk of death.
RESUMEN
BACKGROUND: Tranexamic acid (TA) is used to control bleeding in patients with hemoptysis. However, the effectiveness of the different routes of TA administration has not been studied. RESEARCH QUESTION: Does the nebulized route of TA administration reduce the amount of hemoptysis compared with the IV route in patients presenting to the ED with hemoptysis? STUDY DESIGN AND METHODS: This was a pragmatic, open-label, randomized, parallel, single-center, pilot trial of nebulized TA (500 mg tid) vs IV TA (500 mg tid) in adult patients presenting to the ED with active hemoptysis. The primary outcome was cessation of bleeding at 30 min. Secondary outcomes included amount of hemoptysis at 6, 12, and 24 h; interventional procedures; and side effects of TA. Patients who were hemodynamically unstable or requiring immediate interventional procedure or mechanical ventilation were excluded from the study. RESULTS: Of the 55 patients in each arm, hemoptysis cessation at 30 min following TA administration was significantly higher in the nebulization arm (n = 40) compared with the IV arm (n = 28): χ2 (1, n = 110) = 5.55; P = .0019. Also, hemoptysis amount was reduced significantly in the nebulization arm at all time periods of observation (P value at 30 min = .011, at 6 h = .002, 12 h = .0008, and at 24 h = .005). Fewer patients in the nebulization arm required bronchial artery embolization (13 vs 21; P = .024) and thereby had higher discharge rates from the ED (67.92% vs 39.02%; P = .005). Two patients in the nebulization arm had asymptomatic bronchoconstriction that resolved after short-acting beta-agonist nebulization. No patient discharged from the ED underwent any interventional procedure or revisited the ED with rebleed during the 72 h follow-up period. INTERPRETATION: Nebulized TA may be more efficacious than IV TA in reducing the amount of hemoptysis and need for ED interventional procedures. Future larger studies are needed to further explore the potential of nebulized TA compared with IV TA in patients with mild hemoptysis.

Introduction. Invasive mucormycosis (IM) is a potentially fatal infection caused by fungi of the order Mucorales. Histopathology, culture, and radiology are the mainstays of diagnosis, but they are not sufficiently sensitive, resulting in delayed diagnosis and intervention. Recent studies have shown that PCR-based techniques can be a promising way to diagnose IM.Hypothesis/Gap Statement. Early diagnosis of fungal infections using molecular diagnostic techniques can improve patient outcomes, especially in invasive mucormycosis.Aim. The aim of this study was to evaluate the utility of our in-house mould-specific real time PCR assay (qPCR) in comparison with the commercially available real time PCR (MucorGenius PCR), for the early diagnosis of mucormycosis in tissue samples from patients with suspicion of invasive mucormycosis (IM). This in-house assay can detect and distinguish three clinically relevant mould species, e.g. Aspergillus spp., Mucorales and Fusarium spp. in a single reaction with only one pair of primers, without the need for sequencing.Methodology. We enrolled 313 tissue samples from 193 patients with suspected IM in this prospective study. All cases were classified using EORTC/MSGERC guidelines. All samples were tested using traditional methods, in-house qPCR, and MucorGenius PCR.Results. Using direct microscopy as a gold standard, the overall sensitivity and specificity of in-house qPCR for detection of IM was 92.46% and 80% respectively, while that of the MucorGenius PCR was 66.67% and 90% respectively. However, co-infection of IM and IA adversely affected the performance of MucorGenius PCR in detection of IM.The in-house PCR detected Aspergillus spp. in 14 cases and Fusarium spp. in 4 cases which showed clinical and radiological features of fungal sinusitis. The in-house qPCR also performed better in detecting possible cases of IM. This aids early diagnosis and appropriate treatment to improve patient outcomes.Conclusion. Because the in-house PCR is not only sensitive and specific, but also entirely based on SYBR Green for detection of targets, it is less expensive than probe-based assays and can be used on a regular basis for the diagnosis of IM in resource-constrained settings. It can be used to distinguish between mucormycosis and fungal sinusitis caused by Aspergillus and Fusarium in high-risk patients, as well as to accurately detect Mucorales in fungal co-infection cases.

BACKGROUND: For antiretroviral therapy (ART) naive human immunodeficiency virus (HIV) infected adults suffering from tuberculosis (TB), there is uncertainty about the optimal time to initiate highly active antiretroviral therapy (HAART) after starting antituberculosis treatment (ATT), in order to minimize mortality, HIV disease progression, and adverse events. METHODS: In a randomized, open label trial at All India Institute of Medical Sciences, New Delhi, India, eligible HIV positive individuals with a diagnosis of TB were randomly assigned to receive HAART after 2-4 or 8-12 weeks of starting ATT, and were followed for 12 months after HAART initiation. Participants received directly observed therapy short course (DOTS) for TB, and an antiretroviral regimen comprising stavudine or zidovudine, lamivudine, and efavirenz. Primary end points were death from any cause, and progression of HIV disease marked by failure of ART. FINDINGS: A total of 150 patients with HIV and TB were initiated on HAART: 88 received it after 2-4 weeks (early ART) and 62 after 8-12 weeks (delayed ART) of starting ATT. There was no significant difference in mortality between the groups after the introduction of HAART. However, incidence of ART failure was 31% in delayed versus 16% in early ART arm (p = 0.045). Kaplan Meier disease progression free survival at 12 months was 79% for early versus 64% for the delayed ART arm (p = 0.05). Rates of adverse events were similar. INTERPRETATION: Early initiation of HAART for patients with HIV and TB significantly decreases incidence of HIV disease progression and has good tolerability. TRIAL REGISTRATION: CTRI/2011/12/002260.

Bee sting can lead to allergic reactions which can present as life-threatening emergencies. Kounis syndrome is an acute coronary syndrome caused by mast cell activation after exposure to an allergen. Atrial fibrillation (AF) along with Kounis syndrome after allergen exposure is a rare presentation. A 40-year-old male patient presented to the emergency department (ED) with multiple bee stings to the face and neck. He complained of retrosternal chest pain along with facial pain and swelling. An electrocardiogram (ECG) showed AF with ST elevation in aVR and generalized ST segment depression. Troponin levels were elevated. He was diagnosed with Kounis syndrome along with AF secondary to a bee sting. The patient improved symptomatically with removal of stings and conservative management (steroids, antihistamines, antiplatelet drugs). ECG reverted to sinus rhythm and resolution of ST-T changes. He was discharged from the ED in stable condition. The bee sting may lead to significant cardiovascular events such as AF and Kounis syndrome, which require a high index of suspicion and prompt treatment. Kounis syndrome should be suspected in the ED in young patients with no cardiovascular risk factors after exposure to an allergen.
RESUMEN
Vertigo is not an uncommon presenting symptom in patients presenting to the emergency department (ED) and primary physician's clinic, and around one-tenth of these patients have a central cause, i.e., posterior circulation stroke. HINTS, the acronym for head impulse (HI) test, nystagmus (N), and test of skew (TS), is a neurological examination utilized for differentiating a peripheral cause of vertigo from a sinister central cause. It is a simple, easy-to-do, inexpensive, and less time-consuming test. Here, we present a 27-year young male case without any known comorbidity or trauma, presented to the ED, with complaints of sudden onset isolated vertigo for 2 hours. HINTS examination pointed towards a central cause (normal head impulse test and direction-changing nystagmus). Other neurological and systemic examinations were normal. Non-contrast computed tomography of the brain was normal. Further, computed tomography angiography of head and neck vessels was performed, showing left vertebral artery dissection (VAD). The patient's neurological status deteriorated in the next 8 hours. The patient underwent decompressive craniotomy and got discharged after two weeks. Early performance of the HINTS examination by the primary care physicians and emergency physicians lead to early diagnosis and treatment of this common cause of posterior circulation stroke in young patients. Essential take-home points are the importance of the HINTS test and not to forget VAD as a cause of isolated vertigo without any neck manipulation or trauma.
RESUMEN
Introduction: Triage is a crucial process not only to identify sick patients and prioritize prompt management but also to foster efficient resource utilization. In low-and middle-income countries (LMICs) most emergency departments (ED) still have an informal triage process. Although an important element of emergency care, triage research has not been a priority in LMICs, and hence, very few triage systems have been validated. The All India Institute of Medical Sciences (AIIMS) triage protocol or ATP for adult patients was developed by expert consensus at AIIMS using the Delphi method. We attempted a prospective validation of the ATP in terms of mortality and intensive care unit (ICU)/hospital admission at 24 h. Methods: Patients presenting to the ED, who were 14 years and above were included in the study. The patients were followed up at 24 h and their outcome documented on a standardized data collection form. Mortality and ICU admission were noted at 24 h. Results: A total of 15,505 patients were recruited. After exclusion, among 13,754 patients, 6303 (45.83%) were triaged red and 7451 (54.17%) were triaged yellow. Mortality at 24 h was 10.31% (650) in red triaged patients and 0.35% (26) in yellow triaged patients. The 24-h mortality of red triaged patients was significantly higher (P <0.001) than that of yellow triaged patients. The presence of one or more ATP "Red" criteria was 96.2% (95% confidence interval [CI]: 94.42%-97.47%) sensitive and 56.8% (95% CI: 55.92%-57.63%) specific in predicting 24-h mortality. The sensitivity and specificity of ATP "Red" criteria for 24-h ICU admission were 98.5% (95% CI: 97.7%-99.1%) and 59.6% (95% CI: 58.8%-60.5%), respectively. Conclusion: When applied to adult nontrauma patients, ATP had a high accuracy in recognizing sick patients presenting to the ED. A time-tested and validated triage system like ATP may be a good starting point for public hospital EDs in LMICs.
RESUMEN
BACKGROUND: ST-elevation myocardial infarction (STEMI) is a highly time-sensitive and life-threatening condition. Early recognition and timely management are challenging in a busy emergency department (ED), especially in low/middle-income countries where emergency systems are often fragmented. The aim of our quality improvement (QI) project was to increase the percentage of patients with STEMI undergoing primary percutaneous coronary intervention (PCI) with door to balloon (D2B) time of <90 min by 30% over 12 months. METHODS: As part of the first step in QI, baseline data were collected at different points in the process of care. Using process maps and fishbone analysis, delays in patient registration, ECG and communication with cardiology were identified as some bottlenecks, and change ideas were tested using plan-do-study-act cycles using point-of-care QI methodology. The majority of the change ideas focused on interventions in the ED like strengthening triage, training frontline staff, early diagnosis and quick transportation of patients. RESULTS: During the baseline phase, 22.22% of patients were found to have a D2B time of <90 min. We achieved an increase of 47.78% in patients receiving PCI within 90 min and hence increased to 70% at the end of the intervention phase. Data collected for 4 months after the intervention phase were found to have sustained the effort. CONCLUSION: Significant improvement in the door to reperfusion time resulted from a meticulous assessment of emergency care processes by drawing process flow chart and implementation of change ideas like introduction of fast-track policy for patients with chest pain, reducing staff turnover in the triage area, formal training of staff, continuous engagement with cardiology team and by interchanging of processes which led to a reduction in time to ECG.
