Abstract
BACKGROUND Most studies on bystander cardiopulmonary resuscitation (CPR) for out-of-hospital cardiac arrest (OHCA) have focused on in-hospital or short-term survival. OBJECTIVES The purpose of this study was to examine the association between bystander CPR and long-term survival outcomes for OHCA. METHODS Within the Cardiac Arrest Registry to Enhance Survival, we identified 152,653 patients with OHCA ≥65 years of age or older. Using multivariable hierarchical logistic regression, we first examined the association between bystander CPR and in-hospital survival. Then, among those surviving to discharge and linked to Medicare files, we evaluated the association between bystander CPR and long-term mortality over 5 years using multivariable Cox regression. RESULTS Overall, 58,464 (38.3%) received bystander CPR. Patients receiving bystander CPR were more likely to have an OHCA that was witnessed, in a public location, and with an initial shockable rhythm. Bystander CPR was associated with a 24% higher likelihood of surviving to hospital discharge (10.2% vs 5.5%; adjusted relative risk: 1.24 [95% CI: 1.19-1.29]; P < 0.001), and this survival benefit was similar (interaction P = 0.24) for those who were 65 to 74, 75 to 84, and ≥85 years of age. Among patients surviving to hospital discharge (median follow-up of 31 months), bystander CPR was additionally associated with lower long-term mortality vs those without bystander CPR (adjusted hazard ratio: 0.78 [95% CI: 0.73-0.84]; P < 0.001), and this benefit was also consistent across age groups (interaction P = 0.13). CONCLUSIONS In older adults with OHCA, bystander CPR was associated with higher rates of in-hospital survival. This survival benefit was not attenuated by competing mortality risks but increased in magnitude after hospital discharge.

Treatment of chronic hepatitis D with peginterferon lambda-the phase 2 LIMT-1 clinical trial. Hepatology 2023; 77:2093-2103. [PMID: 36800850 PMCID: PMC10187621 DOI: 10.1097/hep.0000000000000309] [Citation(s) in RCA: 14] [Impact Index Per Article: 14.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/19/2022] [Revised: 12/13/2022] [Accepted: 01/06/2023] [Indexed: 02/22/2023]
Abstract
BACKGROUND AND AIMS HDV infection leads to the most aggressive form of human viral hepatitis for which there is no FDA-approved therapy. PEG IFN-lambda-1a (Lambda) has previously demonstrated a good tolerability profile in HBV and HCV patients compared to PEG IFN-alfa. The goal of Phase 2 LIMT-1 trial was to evaluate the safety and efficacy of Lambda monotherapy in patients with HDV. APPROACH AND RESULTS An open-label study of Lambda 120 or 180 mcg, administered once weekly by subcutaneous injections for 48 weeks, followed by 24 weeks of posttreatment follow-up. Thirty-three patients were allocated to Lambda 180 mcg (n=14) or 120 mcg (n=19). Baseline mean values: HDV RNA 4.1 log10 IU/mL (SD±1.4); ALT 106 IU/L (35-364); and bilirubin 0.5 mg/dL (0.2-1.2). Intention-to-treat rates of virologic response to Lambda 180 mcg and 120 mcg, 24 weeks following treatment cessation were 5 of 14(36%) and 3 of 19 (16%), respectively. The posttreatment response rate of 50% was seen in low BL viral load (≤4 log10) on 180 mcg. Common on-treatment adverse events included flu-like symptoms and elevated transaminase levels. Eight (24%) cases of hyperbilirubinemia with or without liver enzyme elevation, leading to drug discontinuation, were mainly observed in the Pakistani cohort. The clinical course was uneventful, and all responded favorably to dose reduction or discontinuation. CONCLUSIONS Treatment with Lambda in patients with chronic HDV may result in virologic response during and following treatment cessation. Clinical phase 3 development of Lambda for this rare and serious disease is ongoing.

Circ Cardiovasc Qual Outcomes 2022; 15:e009042. [PMID: 36193751 PMCID: PMC9694664 DOI: 10.1161/circoutcomes.122.009042] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/16/2022] [Accepted: 08/11/2022] [Indexed: 11/16/2022]
Abstract
BACKGROUND Most studies on out-of-hospital cardiac arrest have primarily focused on in-hospital or short-term survival. Little is known about long-term outcomes and resource use among survivors of out-of-hospital cardiac arrest. METHODS In this observationsl study, we describe overall long-term outcomes for patients from the national Cardiac Arrest Registry to Enhance Survival linked to Medicare files to create the Cardiac Arrest Registry to Enhance Survival: Mortality, Events, and Costs for Cardiac Arrest survivors dataset. Cardiac Arrest Registry to Enhance Survival data between 2013 and 2019 were linked to Medicare data using probabilistic matching algorithms. Overall long-term mortality, readmissions, and index hospitalization costs are reported for the overall cohort. RESULTS Among 56 425 patients who were 65 years of age or older in Cardiac Arrest Registry to Enhance Survival who survived to hospital admission, 26 875 (47.6%) were successfully linked to Medicare files. Mean (+SD) cost of the index hospitalization was $23 262+$24 199 and the median cost was $14 636 (interquartile range, $9930-$30 033). Overall, 8676 (32.3%) survived to hospital discharge with 38.0% discharged home, 11.8% to hospice care, and the remaining 50.2% to other inpatient, skilled nursing care, or rehabilitation facilities. Mortality after discharge was initially high (27.0% at 3 months) and then increased gradually, with 1- and 3-year mortality of 37.1% and 50.1%, respectively. During the first year, 40.1% were readmitted at least once, with 19.7% readmitted on > 1 occasion. CONCLUSIONS The Cardiac Arrest Registry to Enhance Survival: Mortality, Events, and Costs for Cardiac Arrest survivors registry includes rich data on postdischarge outcomes and resource utilization. Use of this dataset will enable future investigations on the long-term effectiveness, costs, and cost-effectiveness of various interventions for out-of-hospital cardiac arrest in elderly patients.

Factors affecting achievement of glycemic targets among type 2 diabetes patients in South Asia: Analysis of the CARRS trial. Diabetes Res Clin Pract 2021; 171:108555. [PMID: 33242515 PMCID: PMC7854496 DOI: 10.1016/j.diabres.2020.108555] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/29/2020] [Revised: 10/12/2020] [Accepted: 11/10/2020] [Indexed: 11/24/2022]
Abstract
OBJECTIVE To assess the predictors of achieving and maintaining guideline-recommended glycemic control in people with poorly controlled type 2 diabetes. METHODS We analyzed data from the Centre for Cardiometabolic Risk Reduction in South Asia (CARRS) Trial (n = 1146), to identify groups that achieved guideline-recommended glycemic control (HbA1c < 7%) and those that remained persistently poorly controlled (HbA1c > 9%) over a median of 28 months of follow-up. We used generalized estimation equations (GEE) analysis for each outcome i.e. achieving guideline-recommended control and persistently poorly controlled and constructed four regression models (demographics, disease-related, self-care, and other risk factors) separately to identify predictors of HbA1c < 7% and HbA1c > 9% at the end of the trial, adjusting for trial group assignment and site. RESULTS In the final multivariate model, adherence to prescribed medications (RR: 1.46, 95%CI: 1.09, 1.95), adherence to diet plans (RR: 1.79, 95% CI: 1.43, 2.23) and middle-aged: 50-64 years (RR: 1.32; 95% CI: 1.02-1.71) were associated with achieving guideline-recommended control (HbA1c < 7%). Presence of microvascular complications (RR: 0.70; 95%CI: 0.53-0.92) reduced the probability of achieving guideline-recommended glycemic control (HbA1c 7%). Further, longer duration of diabetes (>15 years), RR: 1.41; 95% CI: 1.15, 1.72, hyperlipidemia, RR: 1.19; 95% CI: 1.06, 1.34 and younger age group (35-49 years vs. >64 years: RR: 0.61; 95% CI: 0.47-0.79) were associated with persistently poor glycemic control (HbA1c > 9%). CONCLUSION To achieve and maintain guideline-recommended glycemic control, care delivery models must put additional emphasis and effort on patients with longer disease duration, younger people and those having microvascular complications and hyperlipidemia.

Estimation of the burden of out-of-hospital traumatic cardiac arrest in Karachi, Pakistan, using a cross-sectional capture-recapture analysis. Int J Emerg Med 2020; 13:26. [PMID: 32410575 PMCID: PMC7227293 DOI: 10.1186/s12245-020-00283-z] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/30/2020] [Accepted: 04/26/2020] [Indexed: 11/20/2022] Open
Abstract
Background The burden of trauma-related-out-of-hospital cardiac arrest (OHCA) in developing countries like Pakistan remains largely unexplored due to a lack of organized pre-hospital systems. In order to estimate the burden, we used a two-sample capture-recapture method which has been used in several domains to estimate difficult-to-count populations. Methods We obtained 3-month data from two sources: Records of two major EMS (emergency medical services) systems and five major hospitals providing coverage to the city’s population. All adults with traumatic OHCA were included. Information on variables such as name, age, gender, date and time of arrest, cause of arrest, and destination hospital were obtained for these cases and data were compared to obtain a matched sample. Utilizing an equation and different levels of restrictive criteria, estimates were obtained for burden. Results The EMS records reported 788 and hospital records reported 344 cases of traumatic OHCA. The capture-recapture analysis estimated the annual traumatic OHCA incidence as 45.7/100,000 (95% CI: 44.2 to 47.3). Estimation of the burden from individual hospital or EMS records underestimated and calculated only 14.6% and 33.9% of the total burden, respectively. Most of the traumatic arrest victims had gunshot wound (GSW) (65.2%) followed by road traffic injuries (RTI) (20.8%). Conclusion The actual burden of traumatic OHCA in Pakistan is larger than the burden reported by either the hospitals or EMS services alone. Most of the cases occurred due to GSW and RTI. A multipronged approach is required to manage the problem; from prevention to developing organized trauma care systems and training lay responders in pre-hospital trauma care is vital.

Abstract
Background: We aimed to assess the burden of metabolic syndrome (MetS), and evaluate the phenotypic variation of MetS in a population at high risk for diabetes in urban Karachi, Pakistan. Methods: This study was embedded in a lifestyle intervention trial for the prevention of type 2 diabetes mellitus. The study population comprised participants who belonged to urban households in Karachi, Pakistan. Results: Among 15,590 individuals who were screened through diabetes risk score (DRS), 3945 individuals met the criteria for a high DRS (≥60). After excluding 1780 participants due to refusals and ineligibility, 2165 were enrolled, a total of 1188 subjects (54.9%) met the International Diabetes Federation criteria for MetS, and a total of 1199 subjects (55.4%) participants met the US National Cholesterol Education Program. Raised serum triglycerides (TGs) and low high-density lipoprotein (HDL) cholesterol were significantly associated with MetS. On multivariate logistic regression, higher body mass index levels (obese category: odds ratio [OR] = 2.14, 95% confidence interval [CI] 1.56-2.95), age >44 years (OR = 2.64, 95% CI 1.93-3.60), and family history of diabetes in both parents (OR = 1.71, 95% CI 1.15-2.54) were found to be independently associated with MetS, whereas higher education (OR = 0.78, 95% CI 0.57-1.06) and physical activity levels (OR = 0.74, 95% CI 0.57-0.96) had lower odds of MetS. Conclusion: One in two individuals with a high DRS in an urban low/middle-income country setting met the criteria for MetS. Patients with atherogenic dyslipidemia defined as low HDL and high TGs represent unique subphenotypes of MetS in this population.

Abstract
Objective: Data regarding the etiology, clinical and biochemical patterns in hypopituitarism is scant for Pakistan. We describe the characteristics of patients with hypopituitarism other than sellar and parasellar tumors or traumatic brain injury from a tertiary care center in Pakistan. Methods: We conducted a retrospective descriptive study in the Aga Khan University Hospital, Karachi, Pakistan. We studied all patients presenting with hypopituitarism, between January 2004 and December 2013. Clinical, hormonal and imaging data pertinent to the study was collected according to inclusion criteria. Results: Forty-two patients presented to the endocrinology clinics at the Aga Khan University Hospital during the study period. Thirty-seven patients (88.1%) were females. Mean age ± standard deviation of the participants was 53.8 ± 14.7 years. Sixteen patients had secondary infertility and all were females; a majority of patients in this group had Sheehan’s syndrome (n=8) followed by empty sella syndrome (n=3), partial empty sella syndrome (n=2), idiopathic cause (n=2) and tuberculoma (n=1). Eighteen females (48.6%) reported inability to lactate. Conclusions: Non-traumatic hypopituitarism was more common in women, with Sheehan syndrome being the most common cause of hypopituitarism in our study (35.7%). Secondary hypothyroidism was the most common hormonal deficiency. The most commonly reported symptom was weakness.

Abstract
A cross-sectional study was conducted in the Gastroenterology Clinics of The Aga Khan Hospital and Jinnah Postgraduate Medical Centre in Karachi. All patients complaining of constipation were included. Patients with alarm features were excluded. Interviews were conducted by trained doctors using a structured Rome III based pre-tested questionnaire and Bristol Stool Form Scale. Out of 396 participants, 186 (47.0%) had FC and 209 (52.7%) had IBS-C. Based upon Bristol Stool Form Scale, only 214 (54%) reported to have slow transit constipation (BSS <2). A higher proportion of women reported severe form of constipation as compared to men (81.5%, n=150 vs. 65.1%, n=138 p<0.001). However, a higher percentage of men reported using medications to treat their symptoms (71.2%, n=151 vs. 57.1%, n=105 p=0.003). Proper understanding of patient's symptoms is essential for optimizing individual patient management.

Abstract
BACKGROUND Trauma is the leading cause of death for adults under 44 years of age. Survival after traumatic out-of-hospital cardiac arrest (OHCA) has been reported to be poor, and its epidemiology is not well defined. A few studies have reported better survival in response to pre-hospital life-saving interventions. Currently, no published data on traumatic cardiac arrests in the field exist from low- and lower middle-income countries. We aimed to explore the epidemiology and outcomes of traumatic OHCA patients from Karachi, Pakistan. We conducted a longitudinal cohort study at emergency departments (ED) of five major public and private hospitals of the city from January to April 2013. Data was collected on all adult patients (age 18 years or more) presenting to the hospitals directly from field with cardiac arrest and history of trauma using a structured questionnaire. Patients with do-not-resuscitate status and those referred from other hospitals were excluded. RESULTS During 3 months, a total of 187 patients were enrolled with mean age of 35.1 years. About 95% were men, and 68.4% had a penetrating injury. Even though half of the patients had a witnessed arrest, none received a bystander cardiopulmonary resuscitation (CPR). 83.4% were brought to the hospital in an ambulance, with median response and scene times of 3 and 2 min respectively; however, only 3 received any pre-hospital life-support interventions. One hundred eighty-one patients (96.7%) were pronounced dead on arrival to the ED, and of the remaining 6 patients, 4 received CPR in the EDs. Overall survival at the end of ED stay was 0%. Patients who received life-support interventions survived for longer time, though not clinically significant, as compared to those who did not (45 min vs. 35 min, p = 0.02). CONCLUSION There was no survival after a traumatic OHCA in Karachi, Pakistan. Even though ambulances reached the scene in a very short time, pre-hospital interventions were largely absent. There is a strong need to strengthen our pre-hospital care system but most importantly train the general public to deal with emergencies and be able to provide timely bystander CPR.

Abstract
OBJECTIVE Ramadan is the ninth month in the lunar calendar, during which Muslims fast from predawn to sunset and major changes occur in their dietary, sleep, and physical activity patterns. Most patients with hypothyroidism are unable to comply with the proper timings of levothyroxine (LT4) administration. The objective of the study was to determine the change in thyroid-stimulating hormone (TSH) level and quality of life (QOL) before and after Ramadan in patients with primary hypothyroidism. METHODS This prospective cohort study included adult patients on stable doses of LT4 who fasted for at least 20 days during the month of Ramadan in the Islamic year 1437 Hijri (June/July 2016). Baseline characteristics and TSH levels were recorded on all consenting patients within 6 weeks prior to Ramadan. Post-Ramadan TSH was tested within 1 to 2 weeks after Eid-ul-Fitr. RESULTS During the study period, 64 patients with hypothyroidism were enrolled, of which 58 were female. The mean age of participants was 44.2 ± 13.2 years. Average daily dose of LT4 was 95.3 ± 35.4 μg. On average, patients fasted for 26.5 days and missed a dose of LT4 on 1.27 days. Mean TSH pre-Ramadan was 2.37 ± 1.35 mIU/L, and post-Ramadan, it was 4.69 ± 3.87 mIU/L. Mean difference between TSH pre- and post-Ramadan was 2.32 ± 3.80 mIU/L ( P<.001). However, the difference in TSH was not significantly different between those who were compliant with meals and LT4 interval versus those who were not (compliant, 2.04 mIU/L; noncompliant, 3.15 mIU/L; P = .30). Overall, an increase in QOL scores in the domains of physical health, psychological health, and social relationships was observed after Ramadan. CONCLUSION We observed statistically significant changes in TSH concentrations after the month of Ramadan in hypothyroid patients who fasted. The change in TSH was not affected by timing of LT4 intake and interval from meal. ABBREVIATIONS AKUH = Aga Khan University Hospital; LT4 = levothyroxine; QOL = quality of life; TSH = thyroid-stimulating hormone.

Abstract
OBJECTIVE To assess the application of capture-recapture method as a potential strategy to estimate the incidence of out-of-hospital cardiac arrest. METHODS This cross-sectional study was carried out from January to April 2013 in Karachi and comprised three public general hospitals, one public cardiac hospital, one private general hospital and two ambulance services. Two-sample capture-recapture method was used: first capture was through cardiac arrest data from two major emergency medical services and second capture was from the five teaching hospitals. Records from the hospitals and ambulance services were compared on 7 variables; name, age, gender, date and time of arrest, cause of arrest and destination hospital. Matched and unmatched cases were used in the equation to estimate the incidence of out-of-hospital cardiac arrest. RESULTS Of the 630 out-of-hospital cardiac arrest cases reported, 191(30.3%) related to the emergency medical services records and 439(69.7%) to hospital records. The capture-recapture identified only 9(1.4%) matched cases even with the least restrictive criteria and estimated the annual out-of-hospital cardiac arrest incidence as 166/100,000 population (95% confidence interval: 142.9 to 189.6). CONCLUSIONS Capture-recapture method could be a potential alternative for providing population level data in the absence of organised health information systems.

Abstract
PURPOSE Viral hepatitis B and C represent the primary health challenge confronting Asia and Pakistan. With direct-acting antiviral therapy for hepatitis C, patients will be treated by general physicians (GPs) and will need training through continuing medical education (CME). Blended learning is a combination of didactic teaching with online, self-paced learning, and it has not been evaluated as a CME tool for general physicians. We aimed to compare the change in physician's knowledge about chronic viral hepatitis following a blended learning educational program. METHODS Participants enrolled in a 6 week blended learning program comprising three modules, each of 2 weeks duration. These were: 1) epidemiology and prevention of viral hepatitis; 2) diagnosis and assessment of hepatitis; and 3) treatment of hepatitis. Activities were primarily web based with some face-to-face interactive sessions. All study material was available on the Teach - Pak website. Discussions, questions, and comments were encouraged. An overall pre-and postintervention knowledge assessment was performed, in addition to individual module assessments. RESULTS A total of 48 participants completed the program; 39 passed (81.25%). The participants were from diverse backgrounds with variable previous training. The pass rate rose from 16.1% at the start of the program to 81.2% at the conclusion. The mean pretest score was 26.0 (standard deviation =4.36), while the mean posttest score was 34.6 (standard deviation =5.15), showing an increase in the mean score of 8.56 points. Eighty four percent had completed at least one credit hour for CME as compared to those who did not pass the posttest (44.4% p-value =0.02). No significant differences in results of posttest were observed in the categories of participant's age, years since graduation, or years of experience. The participants were satisfied with the blended learning mode of teaching. CONCLUSION Blended learning is an efficient way to impart hepatitis CME to a diverse group of postgraduate physicians.

[PMID: 28583113 PMCID: PMC5460467 DOI: 10.1186/s12902-017-0179-1] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/15/2016] [Accepted: 05/24/2017] [Indexed: 12/31/2022] Open
Abstract
BACKGROUND Diabetes registry enables practitioners to measure the characteristics and patterns of diabetes across their patient population. They also provide insight into practice patterns which can be very effective in improving care and preventing complications. The aim of this study was to assess the patterns, control levels and complications at the baseline of the patients attending clinic at the large tertiary care hospital in Karachi, Pakistan with the help of the registry. This can be used as a reference to monitor the control and also for a comparison between peer groups. METHODS This was a cross sectional study with the data obtained from diabetes registry collected with the help of pre-designed questionnaire. HbA1c was used as a central diabetes measure and other related factors and complications were assessed with it. RESULTS Only 16.6% of the participants had optimal HbA1c ≤ 7.0%. 52.9% of the patients were classified as having poor control defined by HbA1c of >8%. Three fourth of the study population were obese according to Asian specific BMI cutoffs and majority had type 2 diabetes with duration of diabetes ranging from less than one to about 35 years, mean(SD) duration being 7.6 years (7.1). Overall only 4% of the patients were on combine target of HbA1c, LDL and BP. Results of multivariable logistic regression showed that the odds of having optimal glycemic control increased by 3% with every one year increase in age. In addition, having longer duration of diabetes was associated with 56% lower odds of having good glycemic control. Moreover, having higher triglyceride levels was associated with 1% lower odds of having good glycemic control. CONCLUSION This highlights the large burden of sub optimally controlled people with diabetes in Pakistani population, a low income country with huge diabetes prevalence and ineffective primary health care system creating enormous health and economic burden.

Abstract
OBJECTIVE To determine the prevalence of microalbuminuria and its association with hypertension and other diabetic complications among Type-2 diabetic patients attending at Aga Khan University Hospital Karachi. METHODS 1280 Type-2 diabetes patients who visited the outpatient department of Aga Khan University Hospital from September 2014 to August 2016 were included in the study. Microalbuminuria was diagnosed if spot urinary microalbumin excretion was confirmed to be more than 20mg/l. Hypertension was diagnosed if BP >140/90 or already on antihypertensive medications. Other demographic, clinical and laboratory data were also recorded. RESULTS Microalbuminuria was diagnosed in 404(31.56%) patients and among these albuminuric patients 335(82.9%) had hypertension. They were also dyslipidemic, having raised triglyceride levels, lower HDL levels, with more prevalence of background diabetic retinopathy and peripheral neuropathy. They also showed higher HbA1C levels and longer duration of diabetes. CONCLUSION The prevalence of the microalbuminuria in our patients with Type-2 diabetes is 31.56% and is not only an early sign of diabetic nephropathy but also a host of other diabetic complications and should be dealt early with strict control of their hyperglycemia and hypertension to help prevent the future complications.

Epidemiology and outcomes of out-of-hospital cardiac arrest in a developing country-a multicenter cohort study. BMC Emerg Med 2016; 16:28. [PMID: 27465304 PMCID: PMC4963996 DOI: 10.1186/s12873-016-0093-2] [Citation(s) in RCA: 26] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/21/2015] [Accepted: 07/21/2016] [Indexed: 12/04/2022] Open
Abstract
Background Out-of-hospital cardiac arrest (OHCA) is one of the leading causes of death and disability worldwide. Overall survival after an OHCA has been reported to be poor and limited studies have been conducted in developing countries. We aimed to investigate the rates of survival from OHCA and explore components of the chain of survival in a developing country. Methods We conducted a multicenter prospective cohort study in the emergency departments (ED) of five major public and private sector hospitals of Karachi, Pakistan from January 2013 to April 2013. Twenty-four hour data collection was performed by trained data collectors, using a structured questionnaire. All patients ≥18 years of age, presenting with OHCA of cardiac origin, were included. Patients with do-not-resuscitate status or referred from other hospitals were excluded. Our primary outcome was survival of OHCA patients at the end of ED stay. Results During the three month period, data was obtained from 310 OHCA patients. The overall survival to ED discharge was 1.6 % which decreased to 0 % at 2-months after discharge. More than half (58.3 %) of these OHCA patients were brought to the hospital in a non-EMS (emergency medical service) vehicle i.e. public or private transportation. Patients utilizing non-EMS transportation reached the hospital earlier with a median time of 23 min compared to patients utilizing any type of ambulances which had a delay of 7 min hospital reaching time (median time 30 min). However, patients utilizing ambulances with life-support facilities, as compared to all other types of pre-hospital transportation, had the shortest time to first life-support intervention (15 min). Most of the patients (92.9 %) had a witnessed cardiac arrest out of which only a small percentage (2.3 %) received bystander CPR (cardio pulmonary resuscitation). Median time from arrest to receiving first CPR was 20 min. Only 1 % of patients were found to have a shockable rhythm on first assessment. Conclusion This study showed that the overall survival of OHCA is null in this population. Lack of bystander CPR and weaker emergency medical services (EMS) leading to a delay in receiving life-support interventions were some of the important observations. Poor survival emphasizes the need to standardize EMS systems, initiate public awareness programs and strengthen links in the chain of survival.

Can trained field community workers identify stroke using a stroke symptom questionnaire as well as neurologists? Adaptation and validation of a community worker administered stroke symptom questionnaire in a peri-urban Pakistani community. J Stroke Cerebrovasc Dis 2014; 24:91-9. [PMID: 25440346 DOI: 10.1016/j.jstrokecerebrovasdis.2014.07.030] [Citation(s) in RCA: 12] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/10/2014] [Revised: 07/22/2014] [Accepted: 07/30/2014] [Indexed: 11/26/2022] Open
Abstract
BACKGROUND Stroke is a leading cause of morbidity and mortality worldwide. There is a paucity of data from South Asia where stroke is highly prevalent. Validated tools administrable by community health workers (CHWs) are required to identify stroke in the community in a resource-strapped region such as this. METHODS The study was conducted in a transitional slum in Karachi, Pakistan. Questionnaire to Verify Stroke-Free Status (QVSFS) was adapted and translated into Urdu. Two CHWs, trained by a neurologist, selected 322 community-dwelling subjects using purposive sampling. Each CHW collected data independently, which was validated by a vascular neurologist who directly examined each participant. To assess the effect of audit and feedback, data from the final 10% of the subjects were collected after a second training session for the CHWs. Sensitivity, specificity, and Cohen kappa were determined for the CHW-administered questionnaire against neurovascular assessment. RESULTS Mean age of participants was 56.5 years with 71% of participants being women. The sensitivity and specificity of the questionnaire of detecting stroke was 77.1% (confidence interval [CI], 64.1-86.9) and 85.8% (CI, 83.5-87.5), respectively. The chance-corrected agreement using the Cohen kappa statistic was .51 (CI, .38-.60). Kappa ranged from .37 to .58 for each of the 7 stroke symptoms. Hemianesthesia (72.9%) and hemiplegia (64.6%) were the most sensitive symptoms. The performance and agreement improved from moderate to substantial after audit and feedback. CONCLUSIONS We found a reasonable sensitivity and specificity and moderate agreement between CHW-administered QVSFS and assessment by a vascular neurologist.
