Cardiovascular disease in Hajj pilgrims

Epidemiology of Hajj pilgrimage mortality: Analysis for potential intervention

BACKGROUND

The Saudi Vision 2030 predicts the attendance of 30 million pilgrims each year by 2030. Cost-effective healthcare services during the Hajj are important to manage this increase in the number of pilgrims. Little is known about the impact of the existing chronic diseases on morbidity and mortality during the Hajj. Furthermore, the quality of services provided by Hajj hospitals warrants further study. This study aims to describe patterns of inpatient, all-cause mortality during the Hajj and the relationship between mortality and preexisting chronic diseases as well as the services provided in Hajj hospitals.

METHODS

The population included pilgrims who were admitted to Hajj hospitals in Makkah and sacred sites between 2012 and 2017, excluding 2015. A retrospective, matched, case-control study design was utilized. 2237 cases of mortality were matched to 4474 control cases based on age and gender. The data were extracted from hospital admissions offices and medical records. Hierarchical, logistic regression models were used to examine the medical services. The effect measure modification of the copresence of more than one chronic disease was also examined.

RESULTS

The rate of inpatient all-cause mortality was higher in Makkah hospitals compared to sacred site hospitals. Inpatient, all-cause mortality was significantly associated with diabetes, hypertension, and cardiovascular diseases. Effect measure modification was present between diabetes and cardiovascular diseases, hypertension, and cardiovascular diseases, but not between diabetes and hypertension. Patients who received medical services were more likely to die during their hospital stay compared to patients not receiving services.

CONCLUSION

The current focus on public health issues during the Hajj should be equally distributed between communicable and non-communicable diseases. Although advanced services are provided by Hajj hospitals, interventions to address the increased risks, including mortality, faced by pilgrims with preexisting, chronic diseases should be further investigated and considered.

Understanding the pattern of musculoskeletal pain and its contributing factors among Hajj pilgrims

BACKGROUND

Hajj is a series of rituals that are done in specific areas and periods in Mecca. Performing Hajj requires a great amount of physical demand which may result in musculoskeletal pain (MSP) in different age groups.

OBJECTIVE

To estimate the prevalence of MSP and understand its pattern via exploring the factors that could be associated with muscular pain among pilgrims in the 2022 Hajj.

METHODS

A web-based survey was distributed during the annual Hajj mass gathering. Pilgrims were recruited from Hajj ritual sites. The collected data included demographics, musculoskeletal pain at ten anatomical body sites, and physical activity (PA) level. Descriptive and inferential statistics were used to analyze the data at a 0.05 significance level.

RESULTS

A total of 248 pilgrims participated in the study. The mean age of the sample was 43.49±12.70 years. Of all pilgrims, 78.6% had reported MSP in at least one anatomical body site during performing Hajj. Results revealed that Pilgrims were more likely to have MSP in the lower limb while performing Hajj rituals where the most prevalent reported pain was in the legs (46% ), followed by the lower back (45% ), knees (37% ), and ankles/feet (30% ). Age, sex, and PA were not significantly associated with MSP except the BMI was found to be a significant factor related to MSP among pilgrims (p <0.05).

CONCLUSION

Many pilgrims exhibited pain in at least one body part. Although physical fitness recommendations are published in the Saudi Ministry of Health, MSP preventative measures need to be disseminated by organizations and interested parties worldwide.

Prevalence of emergency cases among pilgrims presenting at King Abdulaziz International Airport Health Care Center at Hajj Terminal, Jeddah, Saudi Arabia during Hajj Season, 1440 H - 2019

Introduction

About 2-3 million pilgrims come to Makkah, Saudi Arabia from all countries to perform Hajj. During the Hajj season of 2019 (1440 H), the total number of pilgrims was 2,489,406, of whom 1,855,027 came from foreign countries. This study aims to investigate the prevalence, pattern, and findings of emergency health problems among pilgrims travelling through King Abdul Aziz International Airport Health Care Center (KAIA-HC) at Hajj Terminal in Jeddah during hajj season of 1440-H.

Methodology

A cross-sectional study was conducted by reviewing the medical records of pilgrims coming for treatment at KAIA-HC, before and after Hajj between 1 Dhul Qi'dah to 29 Dhul Hijjah 1440 AH (Corresponding to 4 July to 31 August 2019 AD). The collected data included demographics, medical history, diagnoses of the emergency health problems, infections, and their findings. Data were analyzed using Epi Info 7 and SPSS 25.

Results

About 296 (3.87%) of 7,643 pilgrims treated at KAIA-HC were emergency cases. Their average age was 43 years (Standard Deviation (SD) ±7.5); 51.3% were females; the highest (45.3%) was between 30 - 59 years age group, both males and females; the highest two nationalities were Indonesian (14.2%) and Egyptian (12.5%). Diagnoses included hypertension 59(19.9%), bronchial asthma 53 (17.9%), and 23 cases (10.5%) were suffering from hypotension. 16 (5.4%) of patients had a myocardial infarction and 10 (3.4%) had cerebrovascular accidents. In 13 cases (4.4%), a chest infection was reported. Diabetes complications (hyperglycemia, hypoglycemia, and diabetic ketoacidosis) were reported in 28 (9.4%) of the cases. There were 28 (9.5%) surgical diagnoses, 13 (4.4%) were cut wounds, 11 (3.7%) were bone fracture and dislocation, and 4 (1.4%) were head trauma. With regard to the findings, 82 (27.7%) were referred to hospitals; 10 (3.3%) cases required Cardio-Pulmonary Resuscitation, seven of whom survived. The most common referral causes were myocardial Infarction amounting 12(4.05%), followed by cerebrovascular accident 10(3.3%) and chest infection in 8 (2.7%). 13 (4.4%) of the total cases died. The most common causes of death were myocardial infarction, asthma, hypertension and hyperglycemia.

Conclusion

Our study emphasizes that emergency cases presented at KAIA-HC were few. Cardiovascular diseases represented the main reason for emergency cases, followed by respiratory diseases. 51% of patients were discharged without the need for a higher level of medical care.

Risk factors for heat-related illnesses during the Hajj mass gathering: an expert review

Human exposure to a hot environment may result in various heat-related illnesses (HRIs), which range in severity from mild and moderate forms to life-threatening heatstroke. The Hajj is one of the largest annual mass gatherings globally and has historically been associated with HRIs. Hajj attracts over two million Muslim pilgrims from more than 180 countries to the holy city of Makkah, Kingdom of Saudi Arabia. Several modifiable and non-modifiable factors render Hajj pilgrims at increased risk of developing HRIs during Hajj. These include characteristics of the Hajj, its location, population, and rituals, as well as pilgrims' knowledge of HRIs and their attitude and behavior. Makkah is characterized by a hot desert climate and fluctuating levels of relative humidity. Pilgrims are very diverse ethnically and geographically, with different adaptations to heat. Significant proportions of the Hajj population are elderly, obese, and with low levels of fitness. In addition, many have underlying health conditions and are on multiple medications that can interfere with thermoregulation. Other factors are inherent in the Hajj and its activities, including crowding, physically demanding outdoor rituals, and a high frequency of infection and febrile illness. Pilgrims generally lack awareness of HRIs, and their uptake of preventive measures is variable. In addition, many engage in hazardous behaviors that increase their risk of HRIs. These include performing rituals during the peak sunshine hours with no sun protection and with suboptimal sleep, nutrition, and hydration, while neglecting treatment for their chronic conditions. HRIs preventive plans for Hajj should incorporate measures to address the aforementioned factors to reduce the burden of these illnesses in future Hajj seasons. Lessons from the Hajj can be used to inform policy making and HRIs preventive measures in the general population worldwide.

The Impact of Classical Cardiovascular Risk Factors on Hospitalization and Mortality among Hajj Pilgrims

Background

Cardiovascular disease (CVD) is the leading cause of morbidity and mortality during Hajj. The objective of the present study was to examine the effect of classical cardiovascular disease risk factors on mortality and hospitalization among Hajj pilgrims from East Java, Indonesia, during 2017, 2018, and 2019.

Methods

This study was a retrospective cohort of Hajj pilgrims from East Java, Indonesia, from 2017 to 2019. The data on risk factors were obtained from the pre-embarkation Hajj screening records. The diagnosis of hospitalization and cause of death during the Hajj period were obtained from the medical report and hospital/flight doctor death certificate.

Results

A total of 72078 eligible subjects were included in this study. 33807 (46.9%) were men, and 38271 (53.1%) were women, and the majority (35%) were aged between 50 and 59 years. A total of 42446 pilgrims (58.9%) were classified as high risk due to underlying health conditions such as hypertension, diabetes, or if they were aged 60 years or older. The overall hospitalization rate is 971 per 100,000 pilgrims and the overall death rate is 240 deaths per 100,000 pilgrims. Multivariate analysis using logistic regression showed that male gender, age > 50 years, hypertension grade II-III, diabetes, overweight, and obesity were associated with a higher risk of hospitalization. Moreover, male gender, diabetes, and overweight were associated with a higher risk of mortality. Of all hospitalized patients, 92 patients (13.1%) had an initial diagnosis of CVD, and CVD is the main cause of mortality (38.2%) of pilgrims.

Conclusion

Pilgrims with classical cardiovascular risk factors were associated with increased hospitalization and mortality.

Determinants of Coronary Heart Disease Incidence among Indonesian Hajj Pilgrims Hospitalized in Saudi Arabia in 2019

BACKGROUND: Cardiovascular diseases (CVDs) are the main causes of death worldwide, including in the hajj pilgrims. Coronary heart disease (CHD) is the most common CVDs in Indonesian hajj pilgrims hospitalized in Saudi Arabia. AIM: This study aimed to determine the determinants of the CHD incidence among Indonesian hajj pilgrims hospitalized in Saudi Arabia in 2019. METHODS: This study was an observational analytic study with a case–control design. The study was conducted in Makassar using data from the integrated Hajj computerized system in the health sector (siskohatkes) Hajj Health Center (Puskeshaji) in January–June 2021. Cases were pilgrims hospitalized in Saudi Arabia with a diagnosis of CHD, about 186 people, and controls were pilgrims hospitalized with diagnoses other than CVDs. Selection of controls by matching age and sex with a ratio of 1:1. The determinants analyzed included education, high blood pressure, high blood sugar levels, high low-density lipoprotein (LDL) cholesterol levels, excess body mass index (BMI), and smoking. Data analysis was using the STATA program with an odds ratio (OR) test and multiple logistic regression. RESULTS: The most respondents were 65 years (48.39%), female respondents, about 61.83%. Most respondents’ education was in elementary school, about 31.99%. Multivariate analysis showed that high blood pressure (OR = 2.32, 95% confidence index [CI] = 1.50–3.57), high blood sugar levels (RO = 1.90, 95% CI = 1.06–3.40), high LDL cholesterol levels (RO = 1.82, 95% CI = 1.15–2.88), and excess BMI (RO = 1.73, 95% CI = 1.07–2.68) were risk factors for the CHD incidence. However, education and smoking were not risk factors for CHD. CONCLUSION: By multiple logistic regression analyzes, the study revealed that the probability of CHD when having those four risk factors was 85.69%.

A Longitudinal Study Regarding the Health Profile of the 2017 South African Hajj Pilgrims

The Hajj mass gathering annually attracts over two million Muslim pilgrims worldwide to the Kingdom of Saudi Arabia (KSA). We aimed to establish demographics and health profiles for the South African pilgrims performing the 2017 Hajj. Methods: This is a longitudinal survey-based study conducted on 1138 adult South African pilgrims in two phases (during and post-Hajj). Data on demographics, vaccination status, underlying health conditions, pre-Hajj training, health promotion, travel history, and health issues during and post-Hajj were collected using pre-designed questionnaires. Results: Participants had a mean age of 49.2 years (SD = 13.3; range 18–81), with a male: female ratio of 1.2:1. The majority of pilgrims were married (88.2%), of Indian/Asian background (73%), and literate (>99%). Nearly all pilgrims were vaccinated against meningococcal disease and yellow fever, but only 23.7% were vaccinated against Influenza. Hypertension, diabetes, and elevated cholesterol levels were the most common underlying health conditions reported by 22.6%, 13.2%, and 11.5% of pilgrims, respectively. One month after return to South Africa, nearly 65% of pilgrims reported illness during Hajj, while 40% reported falling ill post event upon return to South Africa. Nevertheless, only a few were admitted to hospitals (12 during Hajj and 15 post-Hajj). Among ill pilgrims, respiratory symptoms were the most commonly experienced symptoms during (70.2%) and post-Hajj (82.2%). Other symptoms such as walking-related symptoms include symptoms directly related or mainly caused by walking (e.g., leg pain, sore feet, blisters on the feet), dehydration, and gastrointestinal tract symptoms reported during Hajj. Medication to treat respiratory symptoms and antibiotics were the most commonly used medications during and post-Hajj. Having an underlying health condition was an independent predictor of falling ill during or post Hajj. Conclusion: Our study indicates that a sizable proportion of South African pilgrims are elderly with underlying health conditions and most contract respiratory tract infections during and post Hajj. Our study highlights the need for systematic collection of prospective pilgrims’ demographics and health data and more attention to post-Hajj health follow-ups of pilgrims.

The Prevalence and Factors Associated with Musculoskeletal Pain Among Pilgrims During the Hajj

Background

Musculoskeletal pain is a primary burden on individuals as well as social and health care systems. Annually, 2-3 million pilgrims perform the Hajj in Mecca, Saudi Arabia. The Hajj is highly physically demanding because pilgrims generally move by foot for long distances among a series of religious sites, an effort that may exceed their typical levels of physical activity. To understand the impact of musculoskeletal pain on the completion of the Hajj, it is first necessary to evaluate the extent of the problem. Accordingly, this study aimed to estimate the prevalence of musculoskeletal pain and associated factors among pilgrims during the Hajj.

Methods

A cross-sectional survey was conducted during the period of the Hajj. The participants were adult pilgrims ≥ 18 years of age. Data regarding demographics, the prevalence of falls and the point prevalence of musculoskeletal pain by anatomical site were recorded. Participants were allowed to report more than one site of pain. Prevalence, crude and adjusted risk ratios were calculated.

Results

A total of 1715 pilgrims were included in the analysis. The prevalence of falls was 13.76%. The prevalence of overall musculoskeletal pain (pain at any site) was 80.46%. Musculoskeletal pain was most commonly reported in the ankle/foot (38.34%), leg (29.89%), lower back (28.47%) and knee (21.84%). In general, musculoskeletal pain at multiple sites was more common in females and in older and obese individuals. However, there were variations in the importance of sex, age and body mass index as associated factors across different pain sites.

Conclusion

Musculoskeletal pain is common among pilgrims. Unlike most populations examined in other studies, ankle/foot pain was the most common in pilgrims. These data provide guidance for potential preventative programs and the allocation of resources to optimize pilgrims' experiences and ability to complete the Hajj.

Prevalence of Diabetes and Hypertension among Hajj Pilgrims: A Systematic Review

The Hajj mass gathering is attended by over two million Muslims each year, many of whom are elderly and have underlying health conditions. Data on the number of pilgrims with health conditions would assist public health planning and improve health services delivery at the event. We carried out a systematic review of literature based on structured search in the MEDLINE/PubMed, SCOPUS and CINAHL databases, and the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, to estimate the prevalence of diabetes and hypertension among Hajj pilgrims. Twenty-six studies conducted between 1993 and 2018 with a total of 285,467 participants were included in the review. The weighted pooled prevalence rates of hypertension and diabetes among Hajj pilgrims in all included studies were 12.2% (95% CI: 12.0-12.3) and 5.0% (95% CI: 4.9-5.1), respectively. The reported prevalence of other underlying health conditions such as chronic respiratory, kidney or liver disease, cardiovascular disease, cancer and immune deficiency were generally low. Potentially a large number of pilgrims each Hajj have diabetes and/or hypertension and other underlying health conditions. Hajj could be a great opportunity to reduce the burden of these diseases within the over 180 countries participating in the event by identifying undiagnosed cases and optimizing patients' knowledge and management of their conditions. Prospero registration number: CRD42020171082.

Diabetes Care During Hajj

Diabetes mellitus affects over 463 million individuals worldwide. Religious activities such as the Hajj pilgrimage have a major impact on patients with diabetes mellitus, including increasing the risk of hyperglycaemia and hypoglycaemia. This increased risk is due to dietary changes and intense physical activity during pilgrimage while being on antidiabetic medications. Approximately 20% of the pilgrims with underlying illnesses who visit Mecca are diabetic, and complications, such as diabetic ketoacidosis, nonketotic hyperosmolar state, and fatigue/unconsciousness due to hypoglycaemia, have been observed among these patients. Diabetic patients are also at a high risk for foot complications and infections. To avoid any aggravation of the diabetes, a complete biochemical evaluation of the patient must be conducted before Hajj, and the patients must be provided contextualized educational guidance to avert these potential health challenges. This counselling should include the importance of carrying with them at all time their relevant medical history, summaries of the current treatment regimen and emergency snacks. In addition, to reduce the risk of hypoglycaemia, the dosage of insulin should be reduced in selected patients by 20% and that of sulfonylurea should be reduced as needed. Basal insulin and glucagon-like peptide 1 receptor agonists are associated with fewer complications and can be preferentially prescribed. Those patients with type 1 diabetes can continue with the use of insulin pump with suitable education prior to Hajj. For the prevention of foot problems, the use of padded socks and well-fitting shoes is recommended along with an insistence on not walking barefoot. After Hajj, the patient must be followed up, and necessary investigations must be made along with readjustment of insulin dosage in those patients for whom it was reduced. Until the pandemic situation abates, all diabetic patients should avoid making the Hajj journey.

Disparities of demographics, clinical characteristics, and hospital outcomes of AMI pilgrims vs non-pilgrims—tertiary center experience

Background

Acute myocardial infarction (AMI) is usually caused by rupture of an atherosclerotic plaque leading to thrombotic occlusion of a coronary artery. Cardiovascular disease has recently emerged as the leading cause of death during hajj. Our aim is to demonstrate the AMI pilgrim’s related disparities and comparing them to non-pilgrim patients.

Result

Out of 3044 of patients presented with AMI from January 2016 to August 2019, 1008 (33%) were pilgrims. They were older in age (P < 0.001) and showed significantly lower rates cardiovascular risk factors (P < 0.001 for DM, smoking, and obesity). Pilgrims were also less likely to receive thrombolytic therapy (P < 0.001), show lower rate of late AMI presentation (P < 0.001), develop more LV dysfunction post AMI (P < 0.001), and have critical CAD anatomy in their coronary angiography (P < 0.001 for MVD and = 0.02 for LM disease) compared to non-pilgrim AMI patients. Despite AMI pilgrims recorded higher rate of primary percutaneous coronary intervention (PPCI) procedures, they still showed poor hospital outcomes (P < 0.001, 0.004, < 0.001, 0.05, and 0.001, respectively for pulmonary edema, cardiogenic shock, mechanical ventilation, cardiac arrest, and in-hospital mortality, respectively). Being a pilgrim and presence of significant left ventricular systolic dysfunction, post AMI was the two independent predictors of mortality among our studied patients (P = 0.005 and 0.001, respectively).

Conclusion

Although AMI pilgrims had less cardiovascular risk factors and they were early revascularized, they showed higher rates of post myocardial infarction complication and poor hospital outcomes. Implementation of pre-hajj screening, awareness and education programs, and primary and secondary preventive measures should be taken in to consideration to improve AMI pilgrim’s outcome.

An Evaluation of Health Policy Implementation for Hajj Pilgrims in Indonesia

Background: For last decades, the mortality rate of hajj pilgrims from Indonesia was between 2.1 and 3.2 per 1000 hajj pilgrims. At the same time, morbidity affected 87% of the elderly (>65 years old), of which 83% faced high risk of health problems. This is a complex problem affecting hajj health care in Indonesia. The study was aimed to understand what extent of the hajj implementation on health care in Indonesia.

Methods: This review was conducted by abstracting of three studies in Indonesian hajj health care. Two of the studies were based on cross-sectional reviews, while one was a case–control study. The majority of the studies performed laboratory tests to evaluate the disease conditions among hajj pilgrims through secondary data.

Results: First study presented that hajj Posbindu (integrated post-coaching) was not functional in managing the health problems of the pilgrims. It shows that the stroke prevalence is 10.9 per 1000 people, Diabetes Mellitus (DM) 10.9% of the people, and coronary heart disease 1.5%. The second study expressed that, according to health isthitaah (policy implementation), there were 20% hajj pilgrims who delayed their trip because of health issues. Most of them had chronic kidney disease, dementia, or lung tuberculosis. The policy implementation of health isthitaah was not smooth; there was little collaboration between the Ministry of Health and Ministry of Religious Affairs, and the population was not sufficiently educated in the area, resulting in hajj pilgrims with poor knowledge, attitude, and practice in health isthitaah. This notion was enforced in the third study.

Conclusion: The coaching according to health isthitaah should be encouraged alongside collaboration between the Ministry of Health and Ministry of Religious Affairs. Socialization in public health has to increase according to health isthitaah, which can be done by district health centers.

Early discharge (within 24-72 h) in low-risk AMI patients treated with PCI: feasibility and safety-Hajj study

BACKGROUND

Shortening of the hospital stay in patients admitted with the diagnosis of acute myocardial infarction (AMI) has been observed within the last decades. Our center is the only cardiac center in the region providing tertiary care facility and hence receives all AMI patients deemed suitable for invasive assessment and management and this leads to huge required demand. Our aim is to assess feasibility and safety of the early discharge of selected proportion of AMI patients.

RESULT

Out of 557 of patients presented with AMI and treated with percutaneous coronary intervention (PCI), 310 (56%) were discharged early. Men patients and pilgrims were more prevalent among the early discharge group. Early discharged patients had significantly less comorbidities compared to the other group of patients. Moreover, they presented mainly with ST-elevation myocardial infarction (P = 0.04) and treated more with primary percutaneous coronary intervention (PPCI) (P = 0.04). They had favorable coronary anatomy (P = 0.01 and 0.02 for left main and multi-vessel coronary artery disease, respectively), better hospital course, and higher left ventricular ejection fraction compared to non-early discharged patients (P = 0.006 and < 0.001 for pulmonary edema and left ventricular ejection fraction post myocardial infarction). Follow-up of those early discharged patients were promising as majority of them were asymptomatic (95%) and did well post-discharge.

CONCLUSION

Our study demonstrated data that support safety of early discharge in a carefully selected group of AMI patients. Early but safe discharge may have a huge impact on increasing bed availability, reducing hospital costs, and improving patient's satisfaction.

Mass Gathering Medicine (Hajj Pilgrimage in Saudi Arabia): The Outcome of Cardiopulmonary Resuscitation during Hajj

The annual Hajj (pilgrimage) to the Islamic holy shrines at the city of Makkah in the Kingdom of Saudi Arabia is one of the largest yearly recurring mass gatherings worldwide. We aim to evaluate the outcome of outside and inside the hospital cardiopulmonary resuscitation to resuscitate cardiopulmonary arrest among pilgrims. In a prospective cohort study of cardiac arrest patients during Hajj period (January 2004–December 2007 and January 2010–December 2011), 426 patients were resuscitated. The mean age was 64.0 ± 12.0 years. A total of 252 (52.2%) patients had an outside the hospital cardiac arrest, whereas 174 (40.8%) patients had an inside the hospital cardiac arrest. The survival rate of outside the hospital was 5%, whereas inside the hospital was 30%. The overall survival rate was 15.5%. During Hajj, cardiopulmonary resuscitation inside the hospital was associated with better clinical outcomes than outside the hospital. Patients with cardiac arrest outside of the hospital are much less likely to survive due to the lack of immediately trained help and the delay of arrival of aid due to overcrowding. Sudden cardiac arrest leading to death could be minimized if cardiopulmonary resuscitation and defibrillation are delivered before the arrival of emergency medical services.

Indonesian Hajj Cohorts and Mortality in Saudi Arabia from 2004 to 2011

The Hajj is an annual pilgrimage that 1-2 million Muslims undertake in the Kingdom of Saudi Arabia (KSA), which is the largest mass gathering event in the world, as the world's most populous Muslim nation, Indonesia holds the largest visa quota for the Hajj. All Hajj pilgrims under the quota system are registered in the Indonesian government's Hajj surveillance database to ensure adherence to the KSA authorities' health requirements. Performance of the Hajj and its rites are physically demanding, which may present health risks. This report provides a descriptive overview of mortality in Indonesian pilgrims from 2004 to 2011. The mortality rate from 2004 to 2011 ranged from 149 to 337 per 100,000 Hajj pilgrims, equivalent to the actual number of deaths ranging between 501 and 531 cases. The top two mortality causes were attributable to diseases of the circulatory and respiratory systems. Older pilgrims or pilgrims with comorbidities should be encouraged to take a less physically demanding route in the Hajj. All pilgrims should be educated on health risks and seek early health advice from the mobile medical teams provided.

Arbaeen public health concerns: A pilot cross-sectional survey

BACKGROUND

Arbaeen is an annual religious procession in Iraq with an estimated 17-20 million participants. Public health risks associated with such a mass gathering can be serious at both local and global levels. This is the first quantitative examination of risk factors for, and symptoms of, infectious disease among Arbaeen participants.

METHODS

A cross-sectional survey was conducted of a convenience sample of 191 Arbaeen participants in 2017. Interviewers administered a structured questionnaire. Questions included food sources, preventive measures used and symptoms of infectious diseases during the procession.

RESULTS

Data were collected for 191 participants (143 males, 58 females). The most prevalent symptoms were respiratory (runny nose: 22.6%, cough: 22.5%). Diarrhoea was reported by 12.6% of participants, with a strong association with high-income country origin and eating (commercial) street food (odds ratios 6.1 and 4.1, respectively, p < 0.05). All symptoms investigated, except breathlessness, were more prevalent in high-income country participants (p < 0.05).

CONCLUSION

Street food and high-income country origin were independent risk factors for respiratory or gastrointestinal infection symptoms in this sample of Arbaeen participants. However, these results cannot be generalised due to possible selection bias. Further studies are required to inform policy development and health system preparedness to reduce Arbaeen-associated health risks.

Disease Burden on Health Facilities in Governorates South of Karbala During the Arbaeenia Mass Gathering in Iraq in 2014: Cross-Sectional Study

Background

Millions of Iraqi pilgrims travel annually from the southern governorates to Karbala and pass through Thiqar, Muthana, and Diwania Governorates to join the Arbaeenia mass gathering event. During this event, participants are at high risk for diseases and death and stifle local health care resources. In addition, the mass gathering causes considerable burden on health facilities in the hosting localities.

Objective

This study aims to estimate the disease burden on health facilities caused by the pilgrims passing through Thiqar, Muthana, and Diwania Governorates en route to Karbala in Iraq.

Methods

This cross-sectional study was conducted on all health facilities in three governorates (Thiqar, Muthana, and Diwania) situated along the southern way to Karbala from Basra. The study started on December 11, 2014, and ended on December 24, 2014. The morbidity and mortality were collected from surveillance logbooks and death registers. Drug purchase data were obtained from the personnel in charge of the pharmacies. The study period was divided into three phases on the basis of the timing of the mass gathering event: pre-event, the event, and postevent.

Results

There were 884,834 incidents reported during the study. The majority of incidents were reported during the event phase (95%) and were attended mostly at mobile clinics (77%). The average daily incidents during the pre-event, event, and postevent phases were 4300, 56,040, and 4548 incidents, respectively. Musculoskeletal disorders were the most common illness reported (55%). The average number of daily deaths was 43, 36, and 45 during the pre-event, event, and postevent, respectively, and these values did not differ significantly. Cardiovascular diseases (43.5%), injuries (29.8%), and respiratory illnesses (12%) were the leading causes of deaths. Approximately US $1.3 million was spent on drug purchases during this mass gathering in the three governorates.

Conclusions

The Arbaeenia mass gathering causes a tremendous disease and economic burden on governorates that pilgrims pass through to attend this mass gathering in Karbala. Although Iraq’s Ministry of Health is aware of the high burden of this mass gathering on the health facilities in these governorates, more work is needed to ensure quality services during the event.

Real-Time Surveillance of Infectious Diseases and Other Health Conditions During Iraq's Arbaeenia Mass Gathering: Cross-Sectional Study

Background

The most common religious mass gatherings in the Middle East are the Hajj at Mecca in Saudi Arabia, which occurs annually, and the Arbaeenia in Karbala. The importance of developing public health surveillance systems for mass gatherings has been previously emphasized in other reports.

Objective

This study aimed to describe the common illnesses and health conditions affecting people during the Arbaeenia mass gathering in Iraq in 2016.

Methods

A total of 60 data collectors took part in the field data collection over a period of 11 days, from November 12, 2016 to November 22, 2016. Data were collected from 20 health outlets along the major route from Najaf to Karbala (10 health facilities in each governorate). Two digital forms, the Health Facility Survey and the Case Survey, were used for data collection.

Results

A total of 41,689 patients (33.3% female and 66.7% male) visited the 20 health care facilities over a period of 11 days from November 12, 2016 to November 22, 2016. More than three quarters of patients (77.5%; n=32,309) were between 20-59 years of age, more than half of patients were mainly from Iraq (56.5%; n=23,554), and about 38.9% (n=16,217) were from Iran. Patients in this study visited these health care facilities and presented with one or more conditions. Of a total 41,689 patients, 58.5% (n=24,398) had acute or infectious conditions and symptoms, 33.1% (n=13,799) had chronic conditions, 23.9% (n=9974) had traumas or injuries, 28.2% (n=11,762) had joint pain related to walking long distances, and 0.3% (n=133) had chronic dermatologic conditions.

Conclusions

The Arbaeenia mass gathering in 2016 exerted a high burden on the Iraqi health care system. Therefore, efforts must be made both before and during the event to ensure preparedness, proper management, and control of different conditions.

Noncommunicable Disease Emergencies During Arbaeenia Mass Gathering at Public Hospitals in Karbala, Najaf, and Babel Governorates, Iraq, 2014: Cross-Sectional Study

Background

Arbaeenia is the largest religious mass gathering (MG) in Iraq where millions of people from Iraq and many other countries visit Karbala city, south Iraq. MGs are associated with high rates of morbidity and mortality from different noncommunicable diseases (NCDs) such as cardiovascular diseases, diabetes mellitus, and asthma. There is a scarcity of publications that address MGs in Iraq.

Objective

This study aimed to explore the NCD emergencies in public hospitals in Karbala, Najaf, and Babel governorates in Iraq, during the Arbaeenia MG and assess predisposing factors for NCD emergencies.

Methods

The study was conducted from November 27 to December 16, 2014. Data were collected in the pre-event and during MG event from 7 selected hospitals. The pre-event data were collected from emergency room (ER) registers and logbooks, and the data on the MG event were collected daily through direct interview with patients and treating physicians using a structured questionnaire.

Results

In total, 4425 NCD emergencies were recorded. Of these, 80.13% (3546/4425) were collected during the MG event. The NCD emergencies attended at ER hospitals during MG were severe hypertension (HT), diabetes (hyperglycemia), ischemic heart disease (IHD), asthma, and pulmonary edema. The load of NCD emergencies and the daily average emergencies increased 4-fold and 2-fold during the MG event, respectively. Most of the NCD emergencies were treated at ER departments, and a few were hospitalized. Intense physical activities and poor adherence to diet and medication were risk factors for IHD, severe HT, and hyperglycemic diabetes emergencies. Exposure to noxious gases or fumes and recent respiratory infections were risk factors for asthma emergencies.

Conclusions

As the pilgrims approached Karbala city during the Arbaeenia MG, the hospitals on the roads leading to the city experienced an increased load of patients because of different NCD emergencies. Although hospitals should be equipped with the necessary supplies, health education for pilgrims is mandatory, particularly on the factors that can exacerbate their diseases.

A cross-sectional study on factors associated with hypertension and genetic polymorphisms of renin-angiotensin-aldosterone system in Chinese hui pilgrims to hajj

Background

Hypertension is the leading risk factor for cardiovascular disease (CVD), however, the studies on lifestyle and genetic risks in Chinese pilgrims to Hajj was limited. The aim of this study is to examine the prevalence and associated lifestyle and genetic risks for hypertension among Hui Hajj pilgrims in China.

Methods

We performed a cross-sectional analysis of data in 1,465 participants aged 30–70 years who participated in a medical examination for Hui Hajj pilgrims from Gansu province, China in 2017. Multiple logistic regression was used to evaluate the association of potential risk factors with hypertension. Deoxyribonucleic acid (DNA) polymorphism was examined at sites in the renin-angiotensin-aldosterone system (RAAS).

Results

The prevalence of hypertension was 47% among this population. Lifestyle factors such as fried food preference (like vs. dislike: odds ratio [OR]: =1.53, 95% confidence interval [CI]: 1.13–2.09) and barbecued food preference (like vs. dislike: OR = 1.45, 95% CI: 1.06–1.97) were associated with elevated risk of hypertension among Hui pilgrims. Comparing with Angiotensin converting enzyme (ACE) rs4425 AA genotype, TT genotype was associated with hypertension risk (OR = 2.16, 95% CI: 1.17–4.00). Similar results were also observed for ACE rs4437 CC genotype (OR = 1.95, 95% CI: 1.07–3.55), Angiotensin II receptor (ATR) rs129876 AA genotype (OR = 4.10, 95% CI: 2.30–7.32) and Aldosterone synthase (CYP11B2) rs1912 TT genotype (OR = 2.82, 95% CI: 1.57–5.06) genotypes.

Conclusions

Unhealthy lifestyle and genetic factors were associated with the prevalence of hypertension in Chinese Hui pilgrims and their interactions were also observed.

A Tailored, Bundle Care Intervention Strategy to Reduce Cardiac Mortality During the Hajj: A Population-Based, Before and After Study

BACKGROUND

Hajj is the largest human gathering with over 2 million people. We evaluated the effect of bundle care intervention on mortality.

METHODS

A population-based, before and after study compared the effect of an intervention on mortality. The intervention included recruitment of cardiac team, introducing 24/7 catheterization service, cardiac coordination, standardized cardiac care pathways, and establishment of an effective transportation system.

RESULTS

Cardiac mortality accounted for about 52% of all in-hospital deaths before intervention in 2009. This decreased significantly to 43.3%, 32.5%, and 19.7% in 2009, 2010, and 2011, respectively. In-hospital mortality of acute coronary syndromes was 4.7%, 4.6%, and 3.0%, in the years 2009, 2010, and 2011, respectively. Mortality due to other causes remained largely unaffected. There was no significant change in the national mortality due to cardiac causes over the same period provided a reassurance that the observed improvement in in-hospital acute coronary syndrome mortality was not due to overall improvement in health care. The numbers of cardiac catheterization procedures increased 3-fold and cardiac surgical procedures increased 5-fold between 2009 and 2011.

CONCLUSIONS

In this study, we found that an evidence-based intensive bundle care intervention substantially reduced the cardiac mortality among the pilgrims assembling for Hajj in Makkah.

Mass Gatherings and Public Health: Case Studies from the Hajj to Mecca

Background

Many new and challenging risks can be introduced during mass gatherings. The Hajj, as one of the largest mass gatherings, provides an excellent annual opportunity to reflect on the public health risk posed by international and multicultural crowds and the value of mitigation strategies.

Objectives

To identify the gap between preparation and training taken before being exposed to the mass gathering and postexposure experiences, and the breach between the expectations and reality of the holy place.

Methods

This was a qualitative study with in-depth interviews using semistructured questionnaires among Hajjis from 4 different countries (Bangladesh, Pakistan, Myanmar, and New Zealand). Purposive sampling was done. The present study was also supported by literature review.

Findings

Findings pointed to weaknesses in implementation and enforcement of law, for both the custodian country and countries of origin of Hajjis. Disparities among developed and developing countries were also noticeable.

Conclusions

From a global health and human security perspective, strengthening of core capacities in managing mass gatherings as well as researching risks posed by such gatherings are paramount to safeguard the public’s health. Attention of health professionals worldwide and adoption of strategic planning at custodian country and sending countries are obligatory.

The changing trend of cardiovascular disease and its clinical characteristics in Ethiopia: hospital-based observational study

Objective

The aim of this study was to assess the pattern of cardiovascular diseases (CVDs), their clinical characteristics, and associated factors in the outpatient department of the chronic illness clinic of Gondar University Referral Hospital.

Method

A retrospective cross-sectional study was conducted among patients on follow-up at the outpatient chronic illness clinic of the hospital from October 2010 to October 2015. The source population for the study included patients with a diagnosis of CVD whose medical records have the required socio-demographic information during the study period. The data were collected from August 2015 to December 2015. Chi-square and binary logistic regression tests were performed to test the significance of difference among predictive variables and CVDs.

Results

Of 1105 patient medical records, 862 fulfilled the inclusion criteria. The majority of the patients were females (65%) and living in urban areas (62.7%). Hypertension accounted for the majority (62.3%) of CVDs followed by heart failure (HF) (23.9%). Headache was the leading chief complaint among the patients (37.7%) upon diagnosis and was the prominent clinical feature in more than half of the patients during their course of follow-up. Higher proportions of dyslipidemia (85.7%), hypertension (72.8%), and ischemic heart disease (IHD) (73.2%) were associated with urban residency (P<0.01). Patients from rural areas (crude odds ratio [COR] =1.306 [95% confidence interval 1.026–2.166], adjusted odds ratio [AOR] =1.272 [95% confidence interval 1.017–2.030]) and those with comorbidity illnesses (COR= 1.813 [1.279–2.782], AOR =1.551 [95% confidence interval 1.177–2.705]) were more likely to have poor CVD outcome (P<0.05).

Conclusion

Hypertension was found to be the most frequent CVD followed by HF, and hypertensive heart disease was the leading cause of cardiac diseases. Most of the patients had improved assessment in the last follow-up, but patients from rural regions and those with comorbidty had higher likelihood of poor cardiovascular outcome.

Pattern of patients and diseases during mass transit: The day of Arafat experience

Background and Objective:

Every year 2-3 million Muslims gather for a few days around the Holy city of Makkah in Saudi Arabia to perform Hajj. Managing enormous health issues associated with such a mass gathering requires a very vibrant health delivery plan. Related research is part of the strategy. This study was done to assess the pattern of patients and illnesses encountered at one health facility at Arafat on the 2nd day of Hajj, when all the pilgrims move from Mina and stay in Arafat for a few hours. The objective of the study was to provide input so that recommendations can be given for future improvement of health care during this mass transit.

Methods:

All patients reporting sick to the Nimra Hospital on the Day of Arafat were included and documented on a detailed Performa and analyzed.

Results:

We received 211 patients, essentially all of those were in need of acute medical intervention. Acute severe asthma and injuries were the major problems encountered. There were two deaths both related to heat stroke. Patients received were predominantly Arabic speaking.

Conclusions:

Only those needing acute intervention seek medical advice during transit. Well equipped and staffed health facilities are, however, needed to cater these and for any mass casualties. Pre Hajj training and mandatory Flu vaccination can help.

The cardiac patient during Ramadan and Hajj

The holy month of Ramadan is one of the five pillars of Islam. During this month, fasting Muslims refrain from eating, drinking, smoking, and sex from dawn until sunset. Although the Quran exempts sick people from the duty of fasting, it is not uncommon for many heart disease patients to fast during Ramadan. Despite the fact that more than a billion Muslims worldwide fast during Ramadan, there is no clear consensus on its effects on cardiac disease. Some studies have shown that the effects of fasting on stable patients with cardiac disease are minimal and the majority of patients with stable cardiac illness can endure Ramadan fasting with no clinical deterioration. Fasting during Ramadan does not seem to increase hospitalizations for congestive heart failure. However, patients with decompensated heart failure or those requiring large doses of diuretics are strongly advised not to fast, particularly when Ramadan falls in summer. Patients with controlled hypertension can safely fast. However, patients with resistant hypertension should be advised not to fast until their blood pressure is reasonably controlled. Patients with recent myocardial infarction, unstable angina, recent cardiac intervention or cardiac surgery should avoid fasting. Physician advice should be individualized and patients are encouraged to seek medical advice before fasting in order to adjust their medications, if required. The performance of the Hajj pilgrimage is another pillar of Islam and is obligatory once in the lifetime for all adult Muslims who are in good health and can afford to undertake the journey. Hajj is a physically, mentally, emotionally, and spiritually demanding experience. Medical checkups one or two months before leaving for Hajj is warranted, especially for those with chronic illnesses such as cardiovascular disease. Patients with heart failure, uncontrolled hypertension, serious arrhythmias, unstable angina, recent myocardial infarction, or cardiac surgery should be considered unfit for undertaking the Hajj pilgrimage.
