Thirty-year trends of triple burden of disease in the adult population of Pakistan.

BACKGROUND: The triple burden of disease, i.e. communicable diseases, non-communicable diseases and injuries, has significantly affected the healthcare system of Pakistan during the last three decades. Therefore, this study aims to determine and analyse the 30-year disease burden trends through prevalence, death rates and percentages. METHODS: The data for the last three decades, i.e. 1990 to 2019, was extracted from the Global Burden of Disease for Pakistan. Percentage change in prevalence and deaths over 30 years was calculated. Poisson regression analysis was performed to evaluate the triple disease burden trends and the incidence rate ratio. RESULTS: A relative decrease of 23.4% was noted in the prevalence rate of communicable diseases except for human immunodeficiency virus and dengue fever. A relative increase of 1.4% was noted in the prevalence rate of non-communicable diseases. A relative increase of 56.1% was recorded in the prevalence rate of injuries. The prevalence rate ratios of communicable diseases significantly decreased to 0.9796 [95% CI: 0.9887-0.9905], but the prevalence rate of injury increased to 1.0094 [95% CI: 1.0073-1.01145], respectively. CONCLUSION: Pakistan must take the next steps and develop strategies to decrease this burden and mortality rates in the population to create better outcomes and therefore help the healthcare system overall.

Characteristics and Outcomes of Traumatic Cardiac Arrests in the Pan-Asian Resuscitation Outcomes Study.

OBJECTIVE: Little is known about survival outcomes after traumatic cardiac arrest in Asia, or the association of Utstein factors with survival after traumatic cardiac arrests. This study aimed to describe the epidemiology and outcomes of traumatic cardiac arrests in Asia, and analyze Utstein factors associated with survival. METHODS: Traumatic cardiac arrest patients from 13 countries in the Pan-Asian Resuscitation Outcomes Study registry from 2009 to 2018 were analyzed. Multilevel logistic regression was performed to identify factors associated with the primary outcomes of survival to hospital discharge and favorable neurological outcome (Cerebral Performance Category (CPC) 1-2), and the secondary outcome of return of spontaneous circulation (ROSC). RESULTS: There were 207,455 out-of-hospital cardiac arrest cases, of which 13,631 (6.6%) were trauma patients aged 18 years and above with resuscitation attempted and who had survival outcomes reported. The median age was 57 years (interquartile range 39-73), 23.0% received bystander cardiopulmonary resuscitation (CPR), 1750 (12.8%) had ROSC, 461 (3.4%) survived to discharge, and 131 (1.0%) had CPC 1-2. Factors associated with higher rates of survival to discharge and favorable neurological outcome were arrests witnessed by emergency medical services or private ambulances (survival to discharge adjusted odds ratio (aOR) = 2.95, 95% confidence interval (CI) = 1.99-4.38; CPC 1-2 aOR = 2.57, 95% CI = 1.25-5.27), bystander CPR (survival to discharge aOR = 2.16; 95% CI 1.71-2.72; CPC 1-2 aOR = 4.98, 95% CI = 3.27-7.57), and initial shockable rhythm (survival to discharge aOR = 12.00; 95% CI = 6.80-21.17; CPC 1-2 aOR = 33.28, 95% CI = 11.39-97.23) or initial pulseless electrical activity (survival to discharge aOR = 3.98; 95% CI = 2.99-5.30; CPC 1-2 aOR = 5.67, 95% CI = 3.05-10.53) relative to asystole. CONCLUSIONS: In traumatic cardiac arrest, early aggressive resuscitation may not be futile and bystander CPR may improve outcomes.

Improvement in the diagnosis and practices of emergency healthcare providers for heat emergencies after HEAT (heat emergency awareness & treatment) an educational intervention: a multicenter quasi-experimental study.

BACKGROUND: The incidence of heat emergencies, including heat stroke and heat exhaustion, have increased recently due to climate change. This has affected global health and has become an issue of consideration for human health and well-being. Due to overlapping clinical manifestations with other diseases, and most of these emergencies occurring in an elderly patient, patients with a comorbid condition, or patients on poly medicine, diagnosing and managing them in the emergency department can be challenging. This study assessed whether an educational training on heat emergencies, defined as heat intervention in our study, could improve the diagnosis and management practices of ED healthcare providers in the ED setting. METHODS: A quasi-experimental study was conducted in the EDs of four hospitals in Karachi, Pakistan. Eight thousand two hundred three (8203) patients were enrolled at the ED triage based on symptoms of heat emergencies. The pre-intervention data were collected from May to July 2017, while the post-intervention data were collected from May to July 2018. The HEAT intervention, consisting of educational activities targeted toward ED healthcare providers, was implemented in April 2018. The outcomes assessed were improved recognition-measured by increased frequency of diagnosing heat emergencies and improved management-measured by increased temperature monitoring, external cooling measures, and intravenous fluids in the post-intervention period compared to pre-intervention. RESULTS: Four thousand one hundred eighty-two patients were enrolled in the pre-intervention period and 4022 in the post-intervention period, with at least one symptom falling under the criteria for diagnosis of a heat emergency. The diagnosis rate improved from 3% (n = 125/4181) to 7.5% (n = 7.5/4022) (p-value < 0.001), temperature monitoring improved from 0.9% (n = 41/4181) to 13% (n = 496/4022) (p-value < 0.001) and external cooling measure (water sponging) improved from 1.3% (n = 89/4181) to 3.4% (n = 210/4022) (p-value < 0.001) after the administration of the HEAT intervention. CONCLUSION: The HEAT intervention in our study improved ED healthcare providers' approach towards diagnosis and management practices of patients presenting with health emergencies (heat stroke or heat exhaustion) in the ED setting. The findings support the case of training ED healthcare providers to address emerging health issues due to rising temperatures/ climate change using standardized treatment algorithms.

Out of hospital cardiac arrest: experience of a bystander CPR training program in Karachi, Pakistan.

BACKGROUND: Nearly 90% of out-of-hospital cardiac arrest (OHCA) patients are witnessed, yet only 2.3% received bystander cardiopulmonary resuscitation (CPR) in Pakistan. This study aimed to determine retention of knowledge and skills of Hands-Only CPR among community participants in early recognition of OHCA and initiation of CPR in Karachi, Pakistan. METHODS: Pre and post-tests were conducted among CPR training participants from diverse non-health-related backgrounds from July 2018 to October 2019. Participants were tested for knowledge and skills of CPR before training (pre-test), immediately after training (post-test), and 6 months after training (re-test). All the participants received CPR training through video and scenario-based demonstration using manikins. Post-training CPR skills of the participants were assessed using a pre-defined performance checklist. The facilitator read out numerous case scenarios to the participants, such as drowning, poisoning, and road traffic injuries, etc., and then asked them to perform the critical steps of CPR identified in the scenario on manikins. The primary outcome was the mean difference in the knowledge score and skills of the participants related to the recognition of OHCA and initiation of CPR. RESULTS: The pre and post-tests were completed by 652 participants, whereas the retention test after 6 months was completed by 322 participants. The mean knowledge score related to the recognition of OHCA, and initiation of CPR improved significantly (p < 0.001) from pre-test [47.8/100, Standard Deviation (SD) ±13.4] to post-test (70.2/100, SD ±12.1). Mean CPR knowledge after 6 months (retention) reduced slightly from (70.2/100, ±12.1) to (66.5/100, ±10.8). CPR skill retention for various components (check for scene safety, check for response, check for breathing and correct placement of the heel of hands) deteriorated significantly (p < 0.001) from 77.9% in the post-test to 72.8% in re-test. Participants performed slightly better on achieving an adequate rate of chest compressions from 73.1% in post-test to 76.7% in re-test (p 0.27). CONCLUSION: Community members with non-health backgrounds can learn and retain CPR skills, allowing them to be effective bystander CPR providers in OHCA situations. We recommend mass population training in Pakistan for CPR to increase survival from OHCA.

Acceptability of telephone-cardiopulmonary resuscitation (T-CPR) practice in a resource-limited country- a cross-sectional study.

BACKGROUND: T-CPR has been shown to increase bystander CPR rates dramatically and is associated with improved patient survival. OBJECTIVE: To evaluate the acceptability of T-CPR by the bystanders and identify baseline quality measures of T-CPR in Karachi, Pakistan. METHODS: A cross-sectional study was conducted from January to December 2018 at the Aman foundation command and control center. Data was collected from audiotaped phone calls of patients who required assistance from the Aman ambulance and on whom the EMS telecommunicator recognized the need for CPR and provided instructions. Information was recorded using a structured questionnaire on demographics, the status of the patient, and different time variables involved in CPR performance. A One-way ANOVA was used to compare different time variables with recommended AHA guidelines. P-value ≤ 0.05 was considered significant. RESULTS: There were 481 audiotaped calls in which CPR instruction was given, listened to, and recorded data. Out of which in 459(95.4%) of cases CPR was attempted Majority of the patients were males (n = 278; 57.8%) and most had witnessed cardiac arrest (n = 470; 97.7%) at home (n = 430; 89.3%). The mean time to recognize the need for CPR by an EMS telecommunicator was 4:59 ± 1:59(min), while the mean time to start CPR instruction by a bystander was 5:28 ± 2:24(min). The mean time to start chest compression was 6:04 ± 1:52(min.). CONCLUSION: Our results show the high acceptability of T-CPR by bystanders. We also found considerable delays in recognizing cardiac arrest and initiation of CPR by telecommunicators. Further training of telecommunicators could reduce these delays.

Clinical profile and outcomes of adult oncological patients presenting to the emergency department of a tertiary care hospital.

OBJECTIVE: To determine the clinical presentations, diagnosis, and outcomes of oncological patients presenting to the emergency department of a tertiary care hospital. METHODS: The single-centre, cross-sectional study was conducted at the emergency department of the Aga Khan University Hospital, Karachi, from January 1 to December 31, 2018, and comprised all adult patients with diagnosed solid or haematological malignancy. Demographical and clinical data was recorded from medical record files. The immediate outcomes were reported as hospitalisation or discharge from the emergency department. Data was analysed using SPSS 20. RESULTS: Of the 320 patients, 167(52.2%) were females. Overall, 214(66.9) patients were aged 35-64 years. Most of the patients had solid organ malignancy 276(86.2%), with the most common being breast carcinoma 60(18.8%). Among haematological malignancies, B-cell lymphoma 32(10%) was the most common. The most common symptoms at presentation were vomiting 78(24.4%), fever 77(24.1%), and generalised weakness 66(20.6%). Of the total, 240(75%) patients were admitted and 80(25%) were discharged. The most common discharge diagnosis was chemotherapy-induced vomiting, followed by febrile neutropenia and malignant hypercalcaemia. There were 26(10.8%) deaths among the in-patients. CONCLUSIONS: Cancer patients presented to the emergency department with diverse signs and symptoms. It is essential for physicians in the emergency department to be familiar with their presentations in order to initiate prompt and timely management plans for better clinical outcomes.

Perception of the healthcare professionals towards the current trauma and emergency care system in Kabul, Afghanistan: a mixed method study.

BACKGROUND: Trauma and injury contribute to 11% of the all-cause mortality in Afghanistan. The study aimed to explore the perceptions of the healthcare providers (pre and in-hospital), hospital managers and policy makers of the public and private health sectors to identify the challenges in the provision of an effective trauma care in Kabul, Afghanistan. METHODS: A concurrent mixed method design was used, including key-informant interviews (healthcare providers, hospital managers and policy makers) of the trauma care system (N = 18) and simultaneous structured emergency care system assessment questionnaire (N = 35) from July 15 to September 25, 2019. Interviews were analyzed using content analysis approach and structured questionnaire data were descriptively analyzed. RESULTS: Four themes were identified that describe the challenges: 1) pre-hospital care, 2) cohesive trauma management system, 3) physical and human resources and 4) stewardship. Some key challenges were found related to scene and transportation care, in-hospital care and emergency preparedness within the wider trauma care system. Less than 25% of the population is covered by the pre-hospital ambulance system (n = 23, 65.7%) and there is no communication process between health care facilities to facilitate transfer (n = 28, 80%). Less than 25% of patients with an injury requiring emergent surgery have access to surgical care in a staffed operating theatre within 2 h of injury (n = 19, 54.2%) and there is no regular assessment of the ability of the emergency care system to mobilize resources (human and physical) to respond to disasters, and other large-scale emergencies (n = 28, 80%). CONCLUSION: This study highlighted major challenges in the delivery of trauma care services across Kabul, Afghanistan. Systematic improvement in the workforce training, structural organization of the trauma care system and implementing externally validated clinical guidelines for trauma management could possibly enhance the functions of the existing trauma care services. However, an integrated state-run trauma care system will address the current burden of traumatic injury more effectively within the wider healthcare system of Afghanistan.

Implementation of disease-based standard order sets in emergency department of tertiary care hospital, Pakistan - a novel approach for enhancing patient care.

OBJECTIVE: To evaluate the efficacy of disease-based standard order sets in reducing time of order entry, order processing and medication dispensation in emergency department of a tertiary care hospital. METHOD: The pilot study was conducted as part of a retrospective clinical audit using pre- and post-intervention design comprising data from July to September 2013 of the emergency department of a tertiary care hospital in Karachi. Data collected related to the reduction in medicine order entry, processing and dispensing time of eight common emergency conditions with standard order set. Subsequently, standard medication orders for the selected medical conditions were developed together with physicians of emergency and other specialties. Post-intervention data was collected and the two data sets were compared using SPSS version 23.0. RESULTS: Mean medication order entry and processing time from the physician end reduced from 67.7±22.7 seconds to 20.5±7.1 seconds. Mean medication order processing and dispensing time at pharmacist end reduced from 70.0±22.4 to 20.6±8.8 seconds. The difference between pre- and post intervention values was significant (p<0.001). CONCLUSIONS: Implementation of disease-based standard order set significantly improved efficiency.

Etiology of acute undifferentiated fever in patients presenting to the emergency department of a tertiary care center in Karachi, Pakistan.

OBJECTIVE: Our study aimed at identifying the characteristics and etiology of various causes of acute undifferentiated fever in patients presenting to the emergency department of a tertiary care hospital. METHODS: This was a retrospective study conducted at the department of emergency medicine, Aga Khan University Hospital from January to June 2016. Adult patients presenting to Emergency department with acute undifferentiated fever were enrolled. Descriptive statistics were calculated in terms of mean±SD for continuous variables like age of the patients and duration of fever, whereas frequency and percentage were computed for categorical variables like gender and causes of fever. RESULTS: A total of one hundred and fifty five patients were included. Out of these 97 (62.6%) were males and 58 (37.4%) were females. Most patients (25.2%, n= 39) were diagnosed as malaria followed closely by dengue fever (n=33, 21.3%) and then enteric fever (n= 10, 6.5%). while 41.9% (n=65) were diagnosed as suspected viral fever based on clinical judgment and inconclusive laboratory results. CONCLUSION: Malaria was found to be the most common confirmed cause of acute undifferentiated fever followed by dengue and enteric fever. The provision of accurate epidemiological data will enable resources to be directed towards key areas and will be of practical importance to clinicians.

Frequency of ocular emergencies in a tertiary care setting in Karachi, Pakistan - It is time to reduce unnecessary visits.

OBJECTIVE: To examine the frequency of ocular emergencies received in a tertiary care setting.. METHODS: This retrospective clinical audit was undertaken at the Emergency Department of the Aga Khan University Hospital, Karachi, and comprised data of all individuals who presented between January and October 2016. The department's triage database was used to retrieve the data on patient's age, gender, presenting complaints, time and date of presentation. Data was analyzed using SPSS 19. RESULTS: Of the 74729 individuals who presented, 928 (1.2%) presented with ocular complaints. The age range with the highest total number of visits was 0-9 years followed by 20-29 years. A significantly higher proportion of patients with eye complaints presented between 8am and 8pm on weekends (Sundays) compared with weekdays (p< 0.001). There was no significant association between gender and time of visit (p=0.592). The most commonly reported symptom was "eye injury" 368(39.7%). A significantly higher proportion of males presented with eye injury than females (p=0.043). . CONCLUSIONS: Ocular complaints accounted for a reasonable proportion of emergency visits, but many of the visits were unnecessary.

Methanol poisoning: 27 years experience at a tertiary care hospital.

Methanol toxicity can result in serious morbidity and mortality without timely diagnosis and treatment. Many cases of methanol poisoning outbreaks have been noted in our population but no study has been performed to estimate methanol exposure and its outcomes and complications. A retrospective study was conducted to review all the cases of methanol poisoning admitted from January 1988 to December 2015 at the Aga Khan University Hospital. A total of 35 methanol poisoning cases were reported. All the patients were male, and the mean age was 36.2±8.6 years. The mean Glasgow Coma Scale score on presentation in the emergency was 10.4 ± 4.4. Blurring of vision was present in 17 (48%) patients while 10 (28%) had complete blindness. Mean arterial pH was 6.8±0.5 on arrival. Ethanol was given to 30(88%) patients and 12(32%) patients received bicarbonate for immediate treatment. A total of 15 (42.8%) patients underwent dialysis, out of which only 5 (33.3%) patients survived. Overall, 19 (54.3%) patients expired secondary to methanol ingestion.

Trends of acute poisoning: 22 years experience from a tertiary care hospital in Karachi, Pakistan.

OBJECTIVE: To determine the trends of acute poisoning in terms of frequency, nature of poisoning agent, clinical presentation and its outcome. METHODS: The retrospective study was conducted at the Aga Khan University Hospital, Karachi, and comprised data of patients who presented with poisoning between January 1989 and December 2010.The patients were randomly selected , and demographic, chemical information, clinical feature, treatment and outcome were analysed using SPSS 16. RESULTS: Of the total hospital admissions during the period, 3,189(0.3%) were cases of poisoning. Of them, medical records of 705(22%) cases were reviewed; 462(65.5%) adult and 243(34.5%) paediatric cases below 16 years of age. The overall median age was 21 years (interquartile range: 4-32 years)Moreover, 544(87%) were critical at the time of presentation. In 647(92%) cases, the poisoning occurred at home. Psychiatric drugs were found involved in 205(29%) cases, followed by prescription drugs 172(24.4%), pesticides 108(15.3%), hydrocarbons 71(10%), analgesics 59(8.7%), household toxins 59(8.7%), alcohol and drug abuse 21(2.97%) and others 47(6.67%). CONCLUSIONS: Poisoning was a serious cause of morbidity in children and young adults. Medications were the leading cause and home was the most common place of incident.

Prediction of major adverse cardiac events in the emergency department using an artificial neural network with a systematic grid search.

BACKGROUND: The aim of our research was to design and evaluate an Artificial Neural Network (ANN) model using a systemic grid search for the early prediction of major adverse cardiac events (MACE) among patients presenting to the triage of an emergency department. METHODS: This is a single-center, cross-sectional study using electronic health records from January 2017 to December 2020. The research population consists of adults coming to our emergency department triage at Aga Khan University Hospital. The MACE during hospitalization was the main outcome. To enhance the architecture of an ANN using triage data, we used a systematic grid search strategy. Four hidden ANN layers were used, followed by an output layer. Following each hidden layer was back normalization and a dropout layer. MACE was predicted using three binary classifiers: ANN, Random Forests (RF), and logistic regression (LR). The overall accuracy, sensitivity, specificity, precision, and recall of these models were examined. Each model was evaluated using the receiver operating characteristic curve (ROC) and an F1-score with a 95% confidence interval. RESULTS: A total of 97,333 emergency department visits were recorded during the study period, with 33% of patients having cardiovascular symptoms. The mean age was 54.08 (19.18) years old. The MACE was observed in 23,052 (23.7%) of the patients, in-hospital (up to 30 days) mortality in 10,888 (11.2%) patients, and cardiac arrest in 5483 (5.6%) patients. The data used for training and validation were 77,866 and 19,467 in an 80:20 ratio, respectively. The AUC score for MACE with ANN was 0.97, which was greater than RF (0.96) and LR (0.96). Similarly, the precision-recall curve for MACE utilizing ANN was greater (0.94 vs. 0.93 for RF and 0.93 for LR). The sensitivity for MACE prediction using ANN, RF, and LR classifiers was 99.3%, 99.4%, and 99.2%, respectively, with the specificities being 94.5%, 94.2%, and 94.2%, respectively. CONCLUSION: When triage data is used to predict MACE, death, and cardiac arrest, ANN with systemic grid search gives precise and valid outcomes and will benefit in predicting MACE in emergency rooms with limited resources that have to deal with a substantial number of patients.

Occupational injuries reported during vocational training were (n=95, 18%). Males had a higher incidence rates of RTI 3.24[2.35-5.3], falls 1.30 [0.74-2.27], poisonings 2.14 [0.57-7.58] and drownings 2.46(0.84-7.21), while females had a higher incidence rate of burns 2.19 [1.785-3.46].Lack of education 4.6 [1.12 -18.91] (p=0.034), smoking 1.25 [1.05 -2.69] (p=0.049), lack of fathers education 4.71 [2.12 -10.49] (p=<0.001), carrying a gun 6.59 [2.54 -17.11] (p=<0.001), crowded families 3.59 [3.11 -5.07] (p=<0.001), lower family income 2.04 [1.04 -4.02](p=0.039*), lack of helmet use 4.54 [2.12 -9.76] (p=<0.001) and lack of seat belt use 1.3 [1.14 -1.69] (p= <0.001) were significant risk factors for unintentional injuries in youth. Conclusion Added value of the study: This study is one of the first research studies conducted in vocational school youth in Pakistan. It provides the recent rate of unintentional injuries among the youth of Pakistan. High occupational injuries among vocational school youth were reported which needs further research.

Importance of clinical toxicology teaching and its impact in improving knowledge: sharing experience from a workshop.

OBJECTIVE: To assess the impact of a one-day clinical toxicology workshop in improving knowledge. METHODS: A one-day clinical toxicology workshop was conducted as a pre-conference workshop of the Annual Emergency Medicine Conference at the Aga Khan University Hospital, Karachi, in April 2012. The course was composed of poisoning-related common clinical scenarios. The pre-test and post-test understanding was used to assess the impact of the course in improving knowledge. The participants also evaluated the workshop as a whole thorough written evaluation forms. SPSS 19 was ued for statistical analysis of the data. RESULT: There were 22 participants in the course. The pre-test mean score was 31.6 +/- 15.1% (95% CI; 24-40; n = 19) compared to the post-test the mean score of 56.0 +/- 10.8% (95% CI; 47- 61; n = 17). The positive difference was also statistically significant (p < 0.001). The overall workshop was evaluated as excellent by 08 (47.46%) and very good by 10 (52.63%) participants. CONCLUSION: Short training in clinical toxicology improved knowledge of the participants.

Intubation in emergency department of a tertiary care hospital in a low-income country.

OBJECTIVE: To study the indications, method, success rate and complications of intubation at the Emergency Department of a private, tertiary care hospital in Karachi, Pakistan. METHODS: The case series involved 278 patients above 14 years of age who underwent emergency intubation at the Emergency Department of Aga Khan University Hospital, Karachi between 1998 and 2003. Descriptive statistics were used to compare rapid sequence intubation with crash intubation. The level of significance was p<0.05. RESULTS: Of the total 278 intubations performed, 37 (13.3%) had to be left out for incomplete information.The study population remaining for inferential analysis comprised of 241 patients. Of the total 278 patients, 174 (63%) were males. Rapid sequence intubation was the commonest type (n=185, 67%) of intubation and was performed mostly by anaesthetists (n=236, 85%). Cardiogenic pulmonary oedema and head injury were commonly seen in these patients.The success on first attempt of intubation was 98% (n=181) in rapid sequence intubation, and 85% (n=48) in crash intubation. Overall, 15 (5.3%) complications were seen in these intubations. CONCLUSION: Study showed a satisfactory success rate in both rapid sequence and crash intubations.

Trends in mortality related to unintentional poisoning in the South Asian region from 1990 to 2019: analysis of data from the Global Burden of Disease Study.

OBJECTIVE: This study aimed to estimate the burden of unintentional poisoning in South Asian countries from 1999 to 2019. DESIGN: An ecological study conducted at the regional level for South Asian countries, based on data from the Global Burden of Disease Study 2019. SETTING: We extracted unintentional poisoning data from the Global Burden of Disease Study data set from 1990 to 2019 to assess trends in mortality, disability-adjusted life-years (DALYs), years of life lost, years lived with disability (YLDs) and causative agents in South Asian countries (Bangladesh, Bhutan, India, Nepal and Pakistan). OUTCOME MEASURES: We determined the per cent change and 95% CI for the period between 1990 and 2019 by age, gender and country. We also conducted Poisson regression to measure the percentage change in the rate per year. RESULTS: The absolute number of deaths due to unintentional poisoning in South Asia decreased (-32.6%) from 10 558 deaths in 1990 to 7112 deaths in 2019. The age standardised death rate from unintentional poisoning in South Asia has seen a downward trend (-55.88%), declining from 0.87 (0.67-1.01) age-standardised per 100 000 population in 1990 to 0.41 (0.34-0.47) in 2019. Among age groups, under 9 years and 10-19 years have seen downward trends for death and DALYs, accounting for -93.5% and -38.3%, respectively. YLDs have seen an upward trend (5.9%), increasing from 10 461.7 per 100 000 in 1990 to 11 084 per 100 000 in 2019. YLDs in women increased by 7.4%, from 11 558.2 per 100 000 to 12 418.3 per 100 000. The incidence rate ratios (IRRs) adjusted by all age groups and gender for DALYs in all South Asian countries has reduced significantly (IRR 0.97, 95% CI 0.96 to 0.97) from 1990 to 2019. CONCLUSION: This study showed reduction in death and DALYs due to unintentional poisoning in South Asia except YLDs which is showing an increasing trend. Public health systems should continue efforts to minimise and prevent disabilities arising from unintentional poisoning in South Asia.

Parental knowledge attitude and practices about chemical and medicinal poisons: A hospital based study from Karachi, Pakistan.

BACKGROUND: Unintentional poisoning is among the leading cause of death in children less than 20 years age. The incidence of unintentional poisoning in Low-income countries LMICs is four times higher compared to high-income countries (HICs). In Pakistan a 10% (25/211) incidence of unintentional poisonings among 0-15-year-old children has been reported. Most of the poisoning occur because of household chemical and medicines. This study aimed to assess the knowledge, attitude, and practices (KAP) of parents in Karachi regarding poisonous household chemicals and medicines. METHODS: This KAP study was conducted at Aga Khan University Hospital, Karachi from May to August 2019. A maximum sample of 384 was calculated using a 50% knowledge about household chemicals. Data were collected about parental knowledge, attitude and practices about poisons and chemicals at home and presented as frequency and percentages. Chi-square test of independence (or Fisher's exact test) was used. Data were analyzed using SPSS version 20. RESULTS: A total of 364 parents of 0-16-year-old children completed the survey out of which 229 were mothers and 127 were fathers (eight had missing data). We had 70% of parents that kept chemicals and medicines locked in cabinets and 80% chose to never leave medicines unattended, there are still 20-30% parents that need improvement in the parental knowledge and practices for storing chemicals and medicines. A general lack of knowledge regarding poisoning first aid and emergency response centers was noted. CONCLUSIONS: Two-pronged approach for future interventions could be useful; (1) Improving the knowledge and practice among the remaining 20-30% through repeated awareness' sessions for the community. (2) Information regarding PCCS needs to be made readily available to the parents which is a measure useful in cases a child poisoning occurs.

Epidemiology of patients presenting to the emergency department with acute febrile illness in the summer months in Karachi, Pakistan: a cross-sectional study.

Low and middle-income countries, including Pakistan, encounter many acute, undifferentiated fevers in their emergency departments (EDs), especially in the summer. There is a need to understand the prevalence and etiologies of fever to create sustainable risk stratification systems and better identification processes for more efficient treatments. This study aims to determine the patterns, causes, and outcomes of patients presenting to the ED with a fever in the summer months in Karachi, Pakistan. Patients and methods: This was a cross-sectional surveillance study conducted in the summers of 2017 and 2018 in the EDs of four tertiary care hospitals in Karachi, Pakistan. Patients 18 years of age and older, both males and females, that presented with a fever within 48 h were enrolled in the study. The study sample was 5034. Prior comorbidities, medication history, and treatment offered for the illness and diagnosis were noted. The data were stratified by years, that is, 2017-2018. A χ 2-test and a one-way analysis of variance test were applied to check the association between fever presentation in years and covariates. Results: Of the 5034 patients, 3045 (60.5%) presented in 2017 and 1989 (39.5%) presented in 2018. Almost half of the patients who presented with fever to the ED were between 25 and 44 years of age [2383 (47.3%)]. A majority of those presenting were male [3049 (60.6%)]. Most of the patients had a fever recorded between 101 and 102°F [1038 (20.6%)]. The most common accompanying symptoms were headache [2636 (52.4%)] and nausea and vomiting [2274 (45.2%)]. The majority of the patients were diagnosed as viral fever [2390 (47.5%)]. Patients were managed with antibiotics [3342 (66.4%)] and intravenous fluids [2521 (50.1%)] and a majority of patients were discharged [4677 (93.8%)]. Conclusions: Fever is a common presentation in the ED. Understanding the frequency of the causative agent will help improve diagnosis and the judicious use of antibiotics.

Challenges and health outcomes of the exposure to soybean dust in the harbor neighborhood of Karachi, Pakistan: a wake-up call.

BACKGROUND: Chemical disasters are common worldwide and result from technological failure, war, and terrorism activities. Pakistan imports huge quantities of hazardous chemicals to meet its industrial and energy needs. Hence there is a risk of chemical disaster at the ports, during transportation of such material and processing in the chemical industry. This study aimed to review the challenges and health outcomes of cases of soybean dust exposure in Kemari district (harbor neighborhood) of Karachi, Pakistan. METHODS: A cross-sectional survey was conducted with all the affected people from a chemical incident of soybean dust which was reported in the Keamari district of Karachi, Pakistan. Included patients ≥ 18 years who visited the two major tertiary care hospitals of Karachi, Pakistan after the incident between February 17 to 23, 2020. A total of 574 patients were brought to these two major tertiary care hospitals. We collected data on basic demographics, event details, and major signs and symptoms of the affected individuals. Calculated frequencies and percentages for categorical variables. Mean ± standard deviation (SD) was calculated for continuous variables. RESULTS: The mean ± (SD) age of the victims were 32 (13.5) years. Of the 574 patients, majority of the patients (n = 319, 56%) were males. In 28 cases (41%), the onset of symptoms occurred at home, in 27 cases (39%) the onset of symptoms started in the workplace and the remaining cases (n = 14, 20%) experienced the first symptoms while roaming around the roadside. The most common reported co-morbidity was a history of asthma (56%), followed by diabetes mellitus (22%). The most common clinical manifestation was shortness of breath, reported in 94% of the cases, followed by neurological symptoms such as drowsiness, unconsciousness, or seizures experienced by 10% of the victims. A total of 9 deaths (1.5%) were recorded. CONCLUSION: A multi-sectoral systematic approach is also required to address these incidents comprehensively including the trained and equipped pre-hospital system, integrated emergency medical response, and community-wide emergency response system.
