Global childhood unintentional injury surveillance in four cities in developing countries: a pilot study

Objective

To determine the frequency and nature of childhood injuries and to explore the risk factors for such injuries in low-income countries by using emergency department (ED) surveillance data.

Methods

This pilot study represents the initial phase of a multi-country global childhood unintentional injury surveillance (GCUIS) project and was based on a sequential sample of children < 11 years of age of either gender who presented to selected EDs in Bangladesh, Colombia, Egypt and Pakistan over a 3–4 month period, which varied for each site, in 2007.

Findings

Of 1559 injured children across all sites, 1010 (65%) were male; 941 (60%) were aged ≥ 5 years, 32 (2%) were < 1 year old. Injuries were especially frequent (34%) during the morning hours. They occurred in and around the home in 56% of the cases, outside while children played in 63% and during trips in 11%. Of all the injuries observed, 913 (56%) involved falls; 350 (22%), road traffic injuries; 210 (13%), burns; 66 (4%), poisoning; and 20 (1%), near drowning or drowning. Falls occurred most often from stairs or ladders; road traffic injuries most often involved pedestrians; the majority of burns were from hot liquids; poisonings typically involved medicines, and most drowning occurred in the home. The mean injury severity score was highest for near drowning or drowning (11), followed closely by road traffic injuries (10). There were 6 deaths, of which 2 resulted from drowning, 2 from falls and 2 from road traffic injuries.

Conclusion

Hospitals in low-income countries bear a substantial burden of childhood injuries, and systematic surveillance is required to identify the epidemiological distribution of such injuries and understand their risk factors. Methodological standardization for surveillance across countries makes it possible to draw international comparisons and identify common issues.     

Incidence of Physical Injuries in a Rural Community in Sri Lanka: Results of the First Community Survey in Sri Lanka

Background:

Injuries account for approximately 11% of all hospital admissions in Sri Lanka. However, no published data are available with regard to the community incidence of injuries in Sri Lanka.

Objectives:

To determine the community incidence of major intentional and unintentional physical injuries in a rural community in Sri Lanka.

Materials and Methods:

A rural community consisting of 225 families with 1029 inhabitants was studied. Data on major injuries for a period of one year were collected retrospectively.

Results:

There were 85 major injuries in the community during the year of study. This gives a major injury incidence of 82.6 per 1000 person years. This is three times the incidence based on hospital-derived data. Animal bites being the most common cause of injury was noted in 2.3% of the population followed by falls in 1.6%, contact with objects in 1.5%, cut injuries in 1% and road trauma in 1%.

Conclusions:

This study shows a higher incidence of major physical injuries (both intentional and unintentional) in the community than figures derived from hospital data. The prevention of injuries in a community such as the one studied here should be aimed at animal bites, falls, contacts with objects, cut injuries and road trauma.     

Legislation coverage for child injury prevention in China

Objective

To examine the extent to which effective interventions to prevent unintentional child injury are reflected in the laws and regulations of China.

Methods

We focused on the six common causes of fatal child injuries – drowning, road traffic injury, falls, poisoning, burns and suffocation. We investigated 27 interventions recommended by the United Nations Children’s Fund, the World Health Organization or the European Child Safety Alliance. We searched China National Knowledge Infrastructure and Lawyee for Chinese legislations using keywords and synonyms for the 27 interventions. We reviewed the identified legislations for statements specifying the responsible implementation department.

Findings

Seven national laws, nine regulations of the State Council and 46 departmental regulations were found to relate to at least one of the interventions. Although seven of the 27 internationally recommended interventions were covered by Chinese laws, 10 were not covered by any current Chinese law or regulation. None of the interventions against drowning and falls that we investigated was covered by national laws. The implementation responsibilities for effective interventions were either not specified or were assigned to multiple governmental departments in 11 or 20 legislative documents, respectively.

Conclusion

In Chinese laws and regulations, interventions proven to prevent major causes of unintentional child injuries are underrepresented and the associated implementation responsibilities are often poorly defined. China should include all such interventions in laws and regulations, and assign implementation responsibility for each to a single department of the national government.     

The formulation and implementation of a national helmet law: a case study from Viet Nam

Problem

Road traffic injuries are a leading cause of death and disability in Viet Nam. In 2008, official data reported 11 243 deaths and 7771 serious injuries on the roads, of which an estimated 60% of fatalities occur in motorcycle riders and passengers. In recognition of this problem, Viet Nam has had partial motorcycle helmet legislation since 1995. However, for a variety of reasons, implementation and enforcement have been limited.

Approach

On 15 December 2007, Viet Nam''s first comprehensive mandatory helmet law came into effect, covering all riders and passengers on all roads nationwide. Penalties increased ten-fold and cohorts of police were mobilized for enforcement.

Local setting

The Viet Nam national helmet legislation was developed and implemented by the National Traffic Safety Committee.

Relevant changes

Despite past barriers to enforcement, increased policing in 2008 led to 680 000 infringements being issued for non-helmet wearing. While changes in helmet wearing were not nationally observed, significant increases were documented in selected provinces in the first six months of the law’s introduction. In Da Nang, helmet wearing increased from 27 to 99%. In the first three months after the law took effect, surveillance data from 20 urban and rural hospitals, found the risk of road traffic head injuries and deaths decreased by 16% and 18% respectively.

Lessons learnt

Political leadership, intensive advanced public education and stringent enforcement have contributed to the successful implementation of the new law. Through continual monitoring of the legislation, loopholes detrimental to the effectiveness of the law have been identified and addressed.     

Validity of a Surveillance System for Childhood Injuries in a Rural Block of Tamilnadu

Background:

Childhood injuries are increasingly getting the attention of public health experts following WHO''s report on global burden of diseases. Surveillance is an important component of control of any disease and effectiveness of the surveillance system depends upon completeness of the information about occurrence of the health related events to the public health authorities.

Aims:

This study aimed to set up a surveillance system for childhood injuries and validate it by a survey and thereafter estimate the incidence of childhood injuries using capture recapture method.

Settings and Design:

Observational study design.

Materials and Methods:

Passive surveillance system for childhood injuries was created for 26,811 children of less than fourteen years of Kaniyambadi block and it was validated by cross sectional study at the end of surveillance period. Using these two independent information systems, capture recapture method was applied to find out the possible incidence of injuries in the given population at a given period of time.

Statistics:

Chi square, Lincoln Peterson formula for capture re-capture method.

Results:

Surveillance and survey for childhood injuries identified 13.59/1000 child-years (CI: 11.86 - 15.32) and 341.89/1000 child-years (CI: 254.46-429.33) of injury rates, respectively.

Conclusion:

Passive surveillance system underreports childhood injuries markedly but it does identify childhood injuries of serious nature.     

Seasonality of child and adolescent injury mortality in Japan, 2000–2010

Objective

Injury is the leading cause of death among children and adolescents in Japan. Despite this, until now there has been comparatively little research on this phenomenon. The purpose of this study was to examine if there was seasonal variation in child and adolescent injury mortality in Japan in 2000–2010.

Methods

Vital statistics injury mortality data were obtained from the Ministry of Health, Labour and Welfare of Japan. The seasonality of the major causes of unintentional injury (transport accidents, drowning and suffocation) and intentional injury (suicide and homicide) mortality was examined for children and adolescents aged 0–19. Incidence ratios (IR) with 95 % confidence intervals (CI) were calculated to determine the difference between the numbers of observed and expected seasonal deaths.

Results

The annual average injury mortality rate among children and adolescents was 9.0 per 100,000. Deaths from transport accidents, drowning, suffocation and suicide had a significant seasonality. There was a summer peak for transport accidents (IR 1.15, 95 % CI 1.10–1.19) and drowning (IR 2.00, 95 % CI 1.88–2.11), a spring peak for suicide (IR 1.09, 95 % CI 1.04–1.14), while the incidence of suffocation was higher in winter (IR 1.12, 95 % CI 1.03–1.21).

Conclusion

Child and adolescent injury mortality from transport accidents, drowning, suffocation and suicide has a pronounced seasonality in Japan. More research is now needed to find the circumstances underpinning different forms of injury mortality in different periods of the year so that effective interventions can be designed and implemented to reduce the burden of injury mortality among Japanese children.     

Study on Prevalence of lodine Deficiency Disorder and Salt Consumption Patterns in Jammu Region

Research Question:

What is the situation of iodine deficiency disorder (IDD) and salt consumption in Jammu region?

Hypothesis:

The prevalence of IDD has decreased markedly as a result of medical as well as socio-economic factors.

Objective:

To assess the magnitude of IDD in Jammu region and also assess the salt consumption patterns in the region.

Design:

Cross-sectional study.

Setting:

Primary schools in both urban and rural areas.

Study Tools:

Clinical examination of study population for goiter, laboratory assessment of casual urine sample for urinary iodine estimation of I₂ content of salt samples collected from sub-samples of study population.

Participants:

School children in the age group of 6-12 years were selected for study using WHO 30-cluster methodology, urine samples were collected from 15% of selected children and salt samples from 5% of sub-sample.

Ethical Concern:

No ethical issues were involved.

Results:

An overall goiter prevalence of 11.98% was observed in the region. Females had a prevalence of 16.1% and males 10.1%. The median urinary iodine excretion in the region was 96.5 μg/l (range: 29.0-190.0 μg/l). Forty-nine percent of subjects had biochemical iodine deficiency with 6.7% having moderate and 42.53% mild iodine deficiency. In Jammu region, 74.47% of households consume powdered salt with 98.17% powdered salt samples having an I₂ content of greater than 15 ppm.

Conclusion:

Iodine deficiency remains a public health problem in the region, though the region seems to be in a state of nutritional transition from iodine deficiency to iodine sufficiency.     

A Study to Assess Catastrophic Household Expenditure on Childhood Illness in an Urban Slum in Bijapur

Objective:

In this study, the various factors determining the out-of-pocket expenditure on child health care by households are discussed to answer the following questions: How much are households currently spending on child health care? Is there any role of socio-economic status of households on expenditure on child health care? What percentage of their income is spent on child health care and is it catastrophic?

Materials and Methods:

Four slums with a total a population of 7000 were selected for this study. Households where there is history of illness/ sickness in children under 5 years in last one month were included in the study.

Results:

There were a total of 218 episodes of child illness in the households. The household''s belonging to socio- economic class I and II had higher spending on child''s illness per episode as compared to households of socio- economic class III, IV, and V. Socioeconomic status was the key determinant of health care expenditure.

Conclusion:

In this study, it has been found that almost all the households suffered from catastrophic health expenditure.     

Alcohol Use and Implications for Public Health: Patterns of Use in Four Communities

Background:

Alcohol is one of the leading causes of death and disability globally and in India. Information on quantum and pattern of consumption is crucial to formulate intervention programs.

Objectives:

To identify the extent and pattern of alcohol use in urban, rural, town and slum populations using a uniform methodology.

Materials and Methods:

Door-to-door survey was undertaken and simple random sampling methodology was adopted; households were the primary sampling unit. One respondent in each alcohol-user household was randomly chosen for detailed interview.

Results:

Overall, 13% of males and females consumed alcohol. Proportion of users was greater in town (15.7%) and among 26–45 years (67.4%). Whisky (49%) and arrack (35%) were the preferred types and the preferences differed between rural (arrack) and urban (beer) areas. Nearly half (45%) of rural population were very frequent users (consuming daily or every alternate-days) as against users in town (23%) or slum (20%). Two-thirds were long-term users and the proportions were greater in the rural and town areas. While, overall 17% of the users were heavy-users, frequent-heavy-drinking was more in slum and rural areas. Nearly two-thirds consumed alcohol in liquor-shops, restaurants, bars and pubs. Habituation and peer-pressure were the key reasons for alcohol use.

Conclusions:

The study documented alcohol use and patterns of use in four different communities particularly in transitional areas using similar methodology. Many of the patterns identified are detrimental to health both immediate and over the long period of time.     

Viet Nam��s mandatory motorcycle helmet law and its impact on children

Objective

To measure the use of motorcycle helmets in children and to determine the reasons why children wear helmets less often than adults.

Methods

The frequency of helmet wearing among adults and children was ascertained by trained roadside observers, and randomized road user surveys were completed in four major centres in Viet Nam: Hanoi, Ho Chi Minh City, Can Tho and Da Nang. Survey data on key questions were cross tabulated, and χ² was calculated for significant differences between parents and non-parents (0.05).

Findings

The frequency of helmet use in the four study locations ranged from 90–99% among adults, from 15–53% among children ≤ 7 years of age, and from 38–53% among children > 7 but ≤ 14. Of the parents surveyed, 67% said the fear of neck injury was the most important reason their children did not wear a helmet.

Conclusion

Children wear motorcycle helmets much less often than adults. Legislation to penalize adults whose children do not wear motorcycle helmets has been proposed in Viet Nam. Furthermore, ongoing advocacy and social marketing efforts are being made to disseminate information about the safety benefits of helmets to combat erroneous public perceptions.     

A Multi-sectoral Approach to Capture Information on Road Traffic Injuries

Background:

Regularly available data is shown to be inadequate for developing, implementing, and evaluating injury prevention and control programs in India. The present study was undertaken in the hospitals of Bangalore and Pune, to examine the feasibility of gathering information on injuries using multiple sources.

Materials and Methods:

Stakeholders meeting and training programs were held for the hospital staff, police personnel, and traffic and transport staff, to identify their roles and responsibilities. Prospective data on morbidity and mortality due to injuries were collected by trained staff from Emergency Departments on a pre-tested questionnaire. The information gathered was cross-checked with the hospital and police records.

Results:

The stakeholders meeting and training programs were able to motivate the departments to provide the correct data. Data on 32188 patients could be extracted from hospital and police records during the study period. Injuries accounted for 16% of the emergency cases. Unintentional injuries were 64%, and 32% were intentional. Road traffic injuries accounted for 44% of all the injuries. One-third of the injured were children and young adults below 25 years. Among the injured, two wheeler riders were 29% and pedestrians were 23%.

Conclusion:

It was possible to improve the data on injuries by adequate training and a data linking mechanism between the Police, Hospital, and Transport Departments. The problem of road traffic injuries could be highlighted and addressed by a good data capture mechanism.     

General Morbidity Prevalence in the Delhi Slums

Research Question:

What is the sickness prevalence in the slums of a metropolitan city?

Objectives:

To estimate the morbidity prevalence with reference to a socio-economic and demographic perspective of the slum population of Delhi.

Study Design:

A cross-sectional study was conducted and data were collected by a two-stage random sampling method. In the first stage, slum locations were selected and in the second stage households were selected.

Participants:

Data were collected from 1049 households consisting of 5358 individuals'' information.

Results:

The overall morbidity prevalence is 15.4%. It is 14.7 and 16.3% for males and females, respectively but the differences are not statistically significant. The reported higher morbidity prevalence and the illiteracy status are significantly associated. Diseases of the respiratory system appear to be very high among slum dwellers.

Conclusion:

From this study, it can be concluded that the number of years of staying in the slum area, presence of a separate kitchen, type of house, it being Pucca or Kuccha, types of toilet pits or open defecation are the important environmental factors for the reports of higher morbidity patterns from the slum area.     

Routine Immunization - Do People Know About It? A Study Among Caretakers of Children Attending Pulse Polio Immunization in East Delhi

Research question:

Do caretakers of children under five years have sufficient knowledge regarding routine immunization (RI)?

Objective:

To assess the knowledge about RI among caretakers of young children.

Settings:

Pulse polio immunization centres in East Delhi.

Study design:

Cross-sectional study.

Participants:

Six hundred and eighty-two caretakers accompanying children under 5 years to pulse polio booths in November 2006.

Study tool:

Pre-tested semi-open-ended questionnaire.

Statistical analysis:

Proportions, Chi-square test.

Results:

The proportions of respondents who had awareness about different aspects of RI, such as weekday of RI (37.0%), age group for RI (49.1%), number of visits required in the first year of life (27.0%), were all low. When asked to name the four diseases covered under the RI program in Delhi, only 268 (39.3%) could name at least three. The education level of respondents was strongly associated with their knowledge about RI.

Conclusion:

The need of the hour is to make RI a ‘felt need’ of the community. Making caretakers more aware about RI is a vital step in achieving this goal.     

An Evaluation of Coverage and Compliance of Mass Drug Administration 2006 for Elimination of Lymphatic Filariasis in Endemic Areas of Gujarat

Background:

Mass drug administration (MDA) means once-in-a-year administration of diethyl carbamazine (DEC) tablet to all people (excluding children under 2 years, pregnant women and severely ill persons) in identified endemic areas. It aims at cessation of transmission of lymphatic filariasis.

Objective:

What has been the coverage and compliance of MDA in Gujarat during the campaign in December 2006?

Study Design:

Cross-sectional population based house-to-house visit.

Setting:

Urban and rural areas in Gujarat identified as endemic for filariasis where MDA 2006 was undertaken.

Study Variables:

Exploratory - Rural and urban districts; Outcome - coverage, compliance, actual coverage, side effects.

Analysis:

Percentage and proportions.

Results:

Twenty-six clusters, each comprising 32 households from six endemic districts, yielded an eligible population of 4164. The coverage rate was 85.2% with variation across different areas. The compliance with drug ingestion was 89% with a gap of 11% to be targeted by intensive IEC. The effective coverage (75.8%) was much below the target (85%). Side effects of DEC were minimum, transient and drug-specific. Overall coverage was marginally better in rural areas. The causes of poor coverage and compliance have been discussed and relevant suggestions have been made.     

Estimating the Burden of Disease from Unsafe Injections in India: A Cost�Cbenefit Assessment of the Auto-disable Syringe in a Country with Low Blood-borne Virus Prevalence

Background:

Unsafe medical injections are a prevalent risk factor for viral hepatitis and HIV in India.

Objectives:

This review undertakes a cost–benefit assessment of the auto-disable syringe, now being introduced to prevent the spread of hepatitis B virus, hepatitis C virus, and human immunodeficiency virus (HIV).

Materials and Methods:

The World Health Organization methods for modeling the global burden of disease from unsafe medical injections are reproduced, correcting for the concentrated structure of the HIV epidemic in India. A systematic review of risk factor analyses in India that investigate injection risks is used in the uncertainty analysis.

Results:

The median population attributable fraction for hepatitis B carriage associated with recent injections is 46%, the median fraction of hepatitis C infections attributed to unsafe medical injections is 38%, and the median fraction of incident HIV infections attributed to medical injections is 12% in India. The modeled incidence of blood-borne viruses suggests that introducing the auto-disable syringe will impose an incremental cost of $46–48 per disability adjusted life year (DALY) averted. The epidemiological evidence suggests that the incremental cost of introducing the auto-disable syringe for all medical injections is between $39 and $79 per DALY averted.

Conclusions:

The auto-disable syringe is a cost-effective alternative to the reuse of syringes in a country with low prevalence of blood-borne viruses.     

Coverage and use of insecticide-treated bed nets in households with children aged under five years in Liberia

Setting:

St John’s District, Grand Bassa County, Liberia.

Objectives:

In households with children aged <5 years, to examine the coverage and use of long-lasting insecticide-treated bed nets (LLINs), factors associated with non-use and the characteristics and conditions of bed nets.

Design:

Cross-sectional study involving interviews with mothers and visual inspection of LLINs.

Results:

Of 663 households visited, 492 (74%) had no LLIN and 135 (20%) had one LLIN. Of 171 households with LLINs, these were consistently used by 73 (43%) children. The main reasons for inconsistent use included LLINs being old or damaged, and LLINs generating too much heat for 20–30% of children. Visual inspection of LLINs in 130 households showed that 98% of LLINs were white, 20% were not hung above the child’s sleeping place, 30% had holes, 84% were double-bed sized and 82% had been washed in the previous 6 months.

Conclusion:

Despite reports of 100% LLIN coverage in St John’s District, this study showed that only a quarter of households had an LLIN, over half of the children used LLINs inconsistently and the LLINs had several deficiencies. More surveys should be conducted to determine the true coverage of LLINs in Liberia, and measures must be taken to improve the use of LLINs.     

A Study of Occurrence of Domestic Accidents in Semi-Urban Community

Context:

Domestic accidents are worldwide public health problems. The consequences of a domestic accident may prove disastrous as it may result in disability and loss of productivity. In this context, the present study was carried out to characterize the occurrence of domestic accidents in a semi-urban community.

Aims:

To study the incidence of domestic accident in a semi-urban community and its association with various epidemiological factors.

Settings and Design:

Community-based cross-sectional study of 796 households consisting of 4086 individuals residing in a semi-urban area.

Materials and Methods:

Complete information from 796 households consisting of 4086 individuals was collected through semi-structured, pre-tested questionnaire. Domestic accident was considered when any of these individuals had met with an accident inside the house or in the immediate surroundings of the house during the last 6 months from the date of survey. The collected data were tabulated and analyzed.

Statistical Analysis Used:

Simple proportions and Chi-squared test.

Results:

The incidence of domestic accidents was found to be 1.7%. The most common accident reported was fall. Occurrence of falls was found to be associated with age and overcrowding. Other accidents noted were burns, scalds, electrocution, injuries and accidental poisoning. Accidents were reported in significantly higher proportion in extreme age groups and in females. Higher proportion of accidents occurred during the morning and evening hours. About 10.1% were treated at home, 72.5% as outdoor patients and 17.4% as indoor patients. The mean duration of hospital stay was found to be 2 weeks. Full recovery was observed in 82.6% cases, whereas permanent disability was found in only 2.9% subjects, while 14.5% reported chronic pain after the accident. No death related to domestic accident was reported in the present study.

Conclusions:

Domestic accidents are more common in extreme age groups and in females. The reasons may be the higher amount of time spent at home and greater participation in daily home activities. Falls being the most frequent type of accidents, proper designing of house and adequate illumination may help in reducing their occurrence, as the majority of accidents occurred during the morning and evening hours in our study.     

Oesophageal corrosive injuries in children: a forgotten social and health challenge in developing countries

Problem

An unsafe environment is a risk factor for child injury and violence. Among those injuries that are caused by an unsafe environment, the accidental ingestion of corrosive substances is significant, especially in developing countries where it is generally underreported.

Approach

To address this challenging, unmet medical need, we started a humanitarian programme in Sierra Leone. By reviewing the current literature from developing countries and our own experience in the field, we developed a flowchart for management of this clinical condition.

Local setting

This injury is underreported in developing countries. Data available are heavily skewed towards well-resourced centres and do not reflect the entire reality of the condition. Late oesophageal strictures are usually severe. Parent’s lack of knowledge, crowded living conditions and availability of chemicals in and around houses account for most ingestions. The widespread lack of any preventive measures represents the strongest risk factor.

Relevant changes

Timely admission was observed in 19.5% of 148 patients studied. A gastrostomy was performed on 62.1% of patients, 42.8% had recurrent strictures and 19% are still on a continuous dilatation programme. Perforation and death rate were respectively 5.6% and 4%.

Lessons learned

The majority of oesophageal caustic strictures in children are observed late, when dilatation procedures are likely to be more difficult and carry a significantly higher recurrence rate. Gastrostomy is necessary to maintain adequate nutritional status but mothers need training in feeding techniques. Both improvement in nutritional status and sustained oesophageal patency should be the reference points to a successful dilatation.     

Evaluation of Primary Immunization Coverage of Infants Under Universal Immunization Programme in an Urban Area of Bangalore City Using Cluster Sampling and Lot Quality Assurance Sampling Techniques

Research Question:

Is LQAS technique better than cluster sampling technique in terms of resources to evaluate the immunization coverage in an urban area?

Objective:

To assess and compare the lot quality assurance sampling against cluster sampling in the evaluation of primary immunization coverage.

Study Design:

Population-based cross-sectional study.

Study Setting:

Areas under Mathikere Urban Health Center.

Study Subjects:

Children aged 12 months to 23 months.

Sample Size:

220 in cluster sampling, 76 in lot quality assurance sampling.

Statistical Analysis:

Percentages and Proportions, Chi square Test.

Results:

(1) Using cluster sampling, the percentage of completely immunized, partially immunized and unimmunized children were 84.09%, 14.09% and 1.82%, respectively. With lot quality assurance sampling, it was 92.11%, 6.58% and 1.31%, respectively. (2) Immunization coverage levels as evaluated by cluster sampling technique were not statistically different from the coverage value as obtained by lot quality assurance sampling techniques. Considering the time and resources required, it was found that lot quality assurance sampling is a better technique in evaluating the primary immunization coverage in urban area.
