RESUMO
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.

BACKGROUND: Respiratory distress is a common presenting complaint in children brought to the Emergency Department (ED). The Clinical Respiratory Score (CRS) has shown promise as a screen for severe illness in High Income Countries. We aimed to validate the admission CRS in children presenting to the ED of a Low-to Middle Income Country. METHODS: Children (1 month to 16 years) presenting with respiratory distress to the ED of the Aga Khan University Hospital, Karachi, Pakistan, between November 2015 to March 2016, were enrolled. The CRS was measured at initial presentation, prior to any management and 2 h after treatment was started. The predictive value for admission to the paediatric critical care units for a variety of cut offs for CRS at presentation were derived. RESULTS: A total of 112 children (70% male) of median age 12 months (IQR 2, 34.5 months) were enrolled. Patients with severe CRS (score 8-12) at presentation were more likely to be admitted to paediatric critical care (90% vs. 23% with mild-moderate CRS; OR: 5.7; 95% CI: 2.2-15.3, p < 0.001). The sensitivity and specificity of CRS > 3 in predicting outcome were 94% (95% CI 79.8-99.3) and 40% (95% CI 35-45), respectively, with a positive likelihood ratio of 1.6 (95% CI 1.31-1.98) and negative predictive value of 94% (95% CI 81-98). CONCLUSION: An admission CRS of > 3 in the ED of a Low-to Middle Income Country had excellent predictive value for disease severity, and it should be considered for incorporation into ED triage protocols.

BACKGROUND: Road traffic injuries (RTIs) commonly affect the younger population in low- and-middle-income countries. School children may be educated about road safety using storybooks with colorful pictures, which tends to increase the child's interest in the text. Therefore, this study assessed the use of bilingual pictorial storybooks to improve RTI prevention knowledge among school children. METHODS: This pretest-posttest study was conducted in eight public and nine private schools of Karachi, Pakistan, between February to May 2015. Children in grades four and five were enrolled at baseline (n = 410). The intervention was an interactive discussion about RTI prevention using a bilingual (Urdu and English) pictorial storybook. A baseline test was conducted to assess children's pre-existing knowledge about RTI prevention followed by administration of the intervention. Two posttests were conducted: first immediately after the intervention, and second after 2 months. Test scores were analyzed using McNemar test and paired sample t-test. RESULTS: There were 57% girls and 55% public school students; age range 8-16 years. Compared to the overall baseline score (5.1 ± 1.4), the number of correct answers increased in both subsequent tests (5.9 ± 1.2 and 6.1 ± 1.1 respectively, p-value < 0.001). Statistically significant improvement in mean scores was observed based on gender, grades and school type over time (p-value < 0.001). CONCLUSION: Discussions using bilingual pictorial storybooks helped primary school children in Pakistan grasp knowledge of RTI prevention. RTI education sessions may be incorporated into school curricula using storybooks as teaching tools. Potential exists to create similar models for other developing countries by translating the storybooks into local languages.

BACKGROUND: Bomb blast injuries result in premature deaths and burdening of healthcare systems. The objective of this study was to explore the characteristics and outcome of patients presenting to the emergency departments in Pakistan with bomb blast injuries. METHODS: Active surveillance was conducted in seven major emergency departments of Pakistan from November 2010-March 2011. All the sites are tertiary care urban centers. All the patients who presented to the hospital's emergency department (ED) following a bomb blast injury as per self-report or the ambulance personnel were included in the study. Frequency of demographics, injury pattern, and outcomes were calculated. RESULTS: A total of 103 patients with bomb blast injuries presented to the selected emergency departments. The median age of patients was 30 years. Around three-fourth of the patients were males (n = 74, 74.7%). Most of the bomb blast patients were seen in Peshawar (n = 41, 39.8%) and Karachi city (n = 31, 30.1%) and the most common mode of arrival was non-ambulance transport (n = 71, 76.3%). Upper limb injuries (n = 12, 40%) were common in the under 18 age group and lower limb injuries (n = 31, 39.2%) in the 18 years and above group. There were a total of 8 (7.7%) deaths reported out of these 103 patients. CONCLUSION: Bomb blast injuries in Pakistan generally affect young males. Non-ambulance transport is the most common way to access emergency departments (ED). Overall ED mortality is high and capturing data during a disaster in an emergency department is challenging.

INTRODUCTION: Most unintentional injuries among children occur in the home environment. Tip-overs, defined as incidents where heavy objects fall on children due to some type of interaction, are one of the reasons for injuries inside the home. This study aims to determine injury patterns and outcomes for child injuries resulting from tip-overs in the home environment as reported in the emergency department. METHODS: We performed a retrospective chart review of pediatric (under 18 years) tip-overs injuries occurred in years 2010 to 2015 at the Aga Khan University Hospital. Furthermore, parents of injured children participated in phone interviews to provide information about the injury scene. File review and telephonic interviews were conducted in the year 2015 and 2016. RESULTS: A total of 75 children visited the emergency department with tip-over injuries, out of which 55 (73%) were boys. The majority of incidents (75.5%) happened inside the home, and the most common places were the living room and bedroom (32% and 21% respectively). More than half (53%) of the children were not under adult supervision at the time of the incident and less than half (47%) of the household took safety measures after the incident. Tip-over injuries were common among 3-year-old children with decreasing frequency as children grew older. The most common causes of tip-overs were TV/TV trolley (32%), followed by furniture (28%), and wall and roof (23%). The most common sites of injuries were head (n = 33, 44%) and extremities (n = 33, 44%). A majority of the cases (n = 66, 88%) were admitted to the hospital from the emergency department, under care of both general (n = 51, 68%) and critical care units (n = 15, 20%). More than a quarter (n = 27, 36%) required at least one surgical procedure during their hospital stay. The median length of hospital stay was one days (interquartile range, IQR 1-5 days). There were two cases of mortality (3%). CONCLUSION: Most tip-over injuries among children were caused by TV, furniture, and TV trolleys. These injuries can be prevented with public education around home safety measures, such as mounting them on the wall.

BACKGROUND: Dog bite injuries are a common problem globally; however, little is known about the epidemiology of dog bite injury from a low-and-middle-income country like Pakistan. This study aims to determine the epidemiology of dog bite injuries among children and adults from a tertiary care hospital in Karachi, Pakistan. METHODS: We conducted a cross-sectional study on dog bite patients visiting the emergency department from November 2015 to August 2016 of a major public tertiary care hospital. Data was collected using a structured questionnaire on demographic details, bite history, and management of dog bite victims. Descriptive analysis was reported. Chi-square test was applied to check the associations between age-specific dog bite cases and independent variables. RESULTS: 2178 participants were included in the analysis. 715 (38.8%) were children less than 18 years old, and 1463 (61.2%) were adults over 18 years. A majority of the patients were males (1909, 87.7%). Results show that most dog bite injuries (2052, 94.2%) tend to occur outside the house by stray dogs biting without provocation. People aged 18 years and above (61.2%) and males (children: 84.6%, adults: 89.1%) tend to be bitten more often. Lower limbs are most frequently bitten (children: 69.5%, adults: 85.8%). Free-roaming stray dogs (children: 73.4%, adults: 74.9%) were involved in reported biting cases. Many of the patients did not receive appropriate first aid and instead just washed the wound with soap and water (children: 45.1%, adults: 43.7%). 99% of the victims received Tetanus toxoid, Rabies vaccine, and immunoglobulins while in the emergency department. CONCLUSION: There is a high burden of dog bite injuries from stray dogs in Karachi, Pakistan. Efforts should be made to create awareness among the general public on the risks of dog bites and on seeking appropriate first aid and medical attention for a dog bite injury.

OBJECTIVE: To determine the diagnostic accuracy of Pediatric Appendicitis Score (PAS) in predicting appendicitis in children presenting with acute abdominal pain to the Emergency Department (ED) of a private hospital in Pakistan. METHODS: This validation study was through retrospective chart review of children between 4-18 years of age with clinical suspicion of acute appendicitis, presenting to the pediatric ED. Diagnostic accuracy was determined using sensitivity, specificity, predictive values, and area under the curve (AUC). RESULTS: 104 children (76% boys) with mean (SD) age of 10.9 (3.5) years met the eligibility criteria. 91% (n=95) patients had moderate to high PAS (score ³4), and 95% (n=99) had biopsy-proven appendicitis. The likelihood ratio calculated for low, equivocal and high-risk PAS was 0.10, 2.17 and 2.53, respectively. An equivocal PAS (score 4-6) showed a sensitivity of 96.8%, specificity of 80%, positive predictive value of 98.9% and AUC of 0.84 for predicting acute appendicitis. CONCLUSION: PAS showed good diagnostic accuracy in predicting acute appendicitis in children presenting to the ED.

Heat waves are the second leading cause of weather-related morbidity and mortality affecting millions of individuals globally, every year. The aim of this study was to understand the perceptions and practices of community residents and healthcare professionals with respect to identification and treatment of heat emergencies. A qualitative study was conducted using focus group discussions and in-depth interviews, with the residents of an urban squatter settlement, community health workers, and physicians and nurses working in the emergency departments of three local hospitals in Karachi. Data was analyzed using content analysis. The themes that emerged were (1) perceptions of the community on heat emergencies; (2) recognition and early treatment at home; (3) access and quality of care in the hospital; (4) recognition and treatment at the health facility; (5) facility level plan; (6) training. Community members were able to recognize dehydration as a heat emergency. Males, elderly, and school-going children were considered at high risk for heat emergencies. The timely treatment of heat emergencies was widely linked with availability of financial resources. Limited availability of water, electricity, and open public spaces were identified as risk factors for heat emergencies. Home based remedies were reported as the preferred practice for treatment by community members. Both community members and healthcare professionals were cognizant of recognizing heat related emergencies.

INTRODUCTION: Apnoeic oxygenation is a process of delivering continuous oxygen through nasal cannula during direct laryngoscopy. The oxygen that is delivered through these nasal cannulas is either low flow or high flow. Although the effectiveness of apnoeic oxygenation has been shown through systematic reviews and randomised controlled trials, a comparison of high-flow versus low-flow oxygen delivery has not been tested through a superiority study design. In this study we propose to assess the effectiveness of giving low-flow oxygen with head side elevation versus high-flow oxygen with head side elevation against the usual practice of care in which no oxygen is provided during direct laryngoscopy. METHODS AND ANALYSIS: This will be a three-arm study instituting a block randomisation technique with a sample size of 46 in each arm (see table 1). Due to the nature of the intervention, no blinding will be introduced. The primary outcomes will be lowest non-invasive oxygen saturation measurement during direct laryngoscopy and during the 2 min after the placement of the tube and the first pass success rate. The intervention constitutes head side elevation up to 30° for improving glottis visualisation together with low-flow or high-flow oxygen delivery through nasal cannula to increase safe apnoea time for participants undergoing endotracheal intubation. Primary analysis will be intention to treat. ETHICS AND DISSEMINATION: The study is approved by the Ethical Review Committee of Aga Khan University Hospital (2019-0726-2463). The project is an institution University Research Committee grant recipient 192 002ER-PK. The results of the study will be disseminated among participants, patient communities and healthcare professionals in the institution through seminars, presentations and emails. Further, the findings will be published in a highly accessed peer-reviewed medical journal and will be presented at both national and international conferences. TRIAL REGISTRATION NUMBER: ClinicalTrials.gov Registry (NCT04242537).

OBJECTIVE: To assess knowledge and practice trends in managing acute pain in patients infected with human immunodeficiency virus (HIV+) or having acquired immunodeficiency syndrome (AIDS) among emergency physicians of four tertiary care hospitals. Acute pain management in such patients is complex because of multiple concomitant painful conditions related to their disease. After obtaining ethical approval and written informed consent, emergency physicians were requested to fill out a questionnaire. RESULTS: Out of 84 physicians who participated, 49 had managed HIV+/AIDS patients during the preceding year. Out of the 49, 30 (61.2%) physicians stated that they used a combination of analgesics for acute pain in these patients. Forty-two (50%) out of the 84 participants believed that routine doses of opioids were adequate for pain relief, while 42 (50%) agreed that pain management was more complex in these patients mainly due to presence of multiple coexisting problems and psychological issues. Only 26 (31%) respondents considered that pain was under-reported and under-treated in these patients, mainly because physicians were more focused on patients' other disease related complications and issues. Formulation of guidelines are recommended for effective acute pain management in these patients encompassing associated issues, including concomitant painful conditions, opioid dependence, psychiatric problems, etc.

Child abuse is a global problem and pervades all cultures and socio-economic strata. The effects can be profound and life altering for victims. There is substantial literature from high income countries about signs of abuse, but a dearth of data from low and middle income countries like Pakistan. Healthcare professionals (HCP) are ideally placed to detect abuse, but, to inform interventions, an understanding of their experiences, training needs and cultural beliefs is needed. This study aimed to: (1) Explore the challenges that HCP face when managing cases of abuse; (2) Explore cultural beliefs and understand how these shape practice and (3) Identify training needs. A qualitative study using a phenomenological design was conducted. In-depth interviews were conducted with doctors, nurses and security staff in the emergency department of a large private hospital in Pakistan (n = 15). Interviews were undertaken in Urdu, translated into English and analysed using an inductive thematic approach. Multiple challenges were identified. The process of referral to legal services was poorly understood and further training and guidelines was suggested by participants. As the legal system in Pakistan does not allow HCP to keep potentially abused patients in their custody, they felt restricted in their ability to advocate and concerned about the safety of both the identified children and themselves. HCP have potential to detect abuse early; however, in Pakistan there are numerous challenges. HCP require support through training, as well as clear institutional frameworks and legal support to undertake this role.

OBJECTIVE: Health care providers (HCPs) are at risk of occupational exposure to HIV infection. In developing world these exposure occur due to general lack of awareness, education and structured training of HCPs. The objective of the study was to asses if continuing medical education symposium can be used as an effective educational tool to improve attitude, awareness and knowledge regarding occupational exposure to HIV infection. This quasi-experimental study was conducted among HCPs from Karachi, Pakistan. After assessing the baseline knowledge, awareness, and attitude by means of pretest; HCPs were reassessed with posttest after an education symposium on occupational exposure to HIV infection. RESULTS: Among 364 participating HCPs, 14.2% had previous training on post exposure prophylaxis. There was an overall statistically significant (P value < 0.001) improvement in the attitude of the participants. A statistically positive improvement in the number of participants giving correct answer was observed in 9 out of 11 questions (P value < 0.001). The mean score of participants' knowledge before intervention was 6.44 ± 1.84, which improved to 8.82 ± 2.17. Along with the increase in knowledge, a positive change in the attitude regarding safety against HIV was observed after the education symposium.

BACKGROUND: Motor vehicle crash (MVC) related injury has been identified as a major public health concern. Child restrain (CR) seat belts can minimize the mortality and morbidity from MVC. The use for seat belts is substantially low in developing countries like Pakistan even though its use has been shown to decrease morbidity and mortality by a significant extent. METHODS: This was a case control study with cases from the general population (GP) and controls from the Aga Khan University (AKU) employees in a 3:1 ratio. The study questionnaire was based on parameters like gender, education level, awareness and presence of CR and also assessed the frequency of usage, reasons for not using CR and the source of knowledge regarding CR use. RESULTS: Out of 848 respondents, 212 were from AKU and 636 were from the GP. 96.7% from AKU had at least a bachelor's degree while less than half (42.6%) of those from the GP were graduate or above (P<0.001). A statistically significant difference was found between the two groups with drivers from AKU being generally more aware about CR and its use. 81.1% of the group from AKU compared to 59.7% from the general population were found to be aware of child restraint use (P<0.001). Media (40.6%) was found to be the most common source of information amongst the AKU employees. CONCLUSION: Most motor vehicle related injuries in children can be prevented or their severity may be reduced by the use of appropriate child restraint seat belts.
RESUMO
BACKGROUND: Prehospital airway management (AM) is the first priority in the care of emergency and trauma victims as it has shown to improve survival in these patients. OBJECTIVE: The aim of this study was to assess training and knowledge of ambulance staff and availability of AM equipment in ambulances of Karachi, Pakistan. METHODS: This cross-sectional study was conducted from June through September 2014. Interviews were conducted with management of six ambulance service providers and 165 ambulance staff. Data from the management included availability of AM equipment in the ambulances, number and designation of staff sent for emergency calls, and AM training of staff. Ambulance staff were assessed for their awareness, knowledge, and training pertaining to AM. RESULTS: All the ambulance services (A through F) had basic equipment for AM but lacked qualified and trained staff. All services had solo drivers (98.3%) for emergency calls; however, Ambulance Service A also had doctors and paramedics. Only 35.7% (59/165) of ambulance staff had awareness regarding AM, out of which 77.9% (46/59) belonged to Ambulance Service A. Of these 59 staff, 81.4% received some form of AM training. Staff with AM awareness, when assessed for knowledge pertaining to AM steps and AM equipment, had a mean score of 4.7/5 and 8.4/12, respectively. CONCLUSION: Even though ambulances are equipped with basic equipment, due to lack of trained staff, these ambulances only serve the mere purpose of transportation. There is a need to train ambulance staff and increase ambulance to staff ratio to improve prehospital AM and patient survival.
