Estimating the burden of congenital rubella syndrome in Costa Rica, 1996-2001

BACKGROUND: The epidemiology of rubella in Costa Rica changed during recent decades, shifting the susceptible groups to the reproductive age. This study estimates the burden of congenital rubella syndrome (CRS) from 1996 to 2001 in this country. METHODS: Three methods to calculate CRS incidence were used. A retrospective search ("Observed cases") was conducted using hospital discharge records of children born from 1996 to 2001 with selected codes of ICD9 and ICD10 consistent with CRS and children <3 months of age with a positive serologic test for rubella IgM antibody at the National Children's Hospital (NCH). Cases were classified as either suspected, compatible or confirmed CRS and congenital rubella infection. "Expected" incidence of CRS was calculated using reported cases of rubella (women 15-45 years of age) and fertility rates, assuming CRS probability of 0.9 during the first trimester of pregnancy and 0.5 of asymptomatic rubella cases. "Estimated" CRS cases were calculated using incidence rates reported from modeling analysis during epidemic and endemic years. RESULTS: Of the 577 discharge charts reviewed and the 66 children reported as rubella IgM(+), 40 compatible CRS cases, 45 confirmed, and 4 with congenital rubella infection cases were identified. The range of annual incidence rate of CRS (per 1000 live births) was as follows: "Observed" = 0.00-0.33, "Expected" = 0.00-0.35 and "Estimated" = 0.5-1.5. Compared with the estimated number of CRS cases, only 27.2% of CRS cases were detected from the retrospective search and 10.1% would be expected when calculated using rubella reported cases. CONCLUSIONS: The under-detection of CRS cases using rubella reported cases in women of reproductive age and retrospective search of CRS reinforces the importance of suspecting CRS in the presence of a single compatible manifestation. Laboratory confirmation is indispensable to implement CRS elimination strategies and should be done in every suspected case.     

Burden of congenital rubella syndrome after a community-wide rubella outbreak,Rio Branco,Acre, Brazil, 2000 to 2001

BACKGROUND: During 1999 and 2000 rubella outbreaks were reported in 20 of 27 states in Brazil, many among young adults. We investigated a large rubella outbreak in Rio Branco, Acre, in northwestern Brazil, where rubella vaccination targeting children 1 to 11 years old had been introduced in April 2000. Surveillance for congenital rubella syndrome (CRS) was initiated after the outbreak. METHODS: Suspected rubella cases were detected through active and passive surveillance. Confirmed rubella cases were patients with fever, rash and rubella-specific IgM antibodies. Suspected CRS cases were infants born with CRS-compatible defects or born to mothers with a history of rubella during pregnancy. Confirmed cases were infants with CRS-compatible defects and rubella-specific IgM antibodies. RESULTS: From April 1 to December 31, 2000, 391 confirmed rubella cases were reported. The incidence among persons ages 12 to 19 years (3.3 per 1000 population) was increased 3.7-fold relative to children ages 1 to 4 years (95% confidence interval, 2.4 to 5.8). Of 21 infants with suspected CRS cases, 17 (91%) were tested for rubella-specific antibodies, of whom 7 were IgM-positive and 5 had confirmed CRS. The peak incidence of confirmed CRS (4.3 per 1000) was in March 2001, 7 months after the outbreak peak, with an annualized incidence of 0.6 per 1000. CONCLUSIONS: Vaccination among school age children was insufficient to prevent a rubella outbreak among young adults that resulted in the occurrence of at least 5 cases of CRS. To prevent further cases of CRS, outbreak vaccination of young adults was conducted in November 2000 and among women ages 12 to 39 years in 2001 as part of a national campaign, with a coverage of 98% statewide.     

Fetal risk associated with rubella vaccination during pregnancy

BACKGROUND: Costa Rica implemented a nationwide measles-rubella vaccination campaign among men and women (15-39 years old) in May 2001. A protocol was developed to follow-up the vaccinated women who were unknowingly pregnant, to determine the risk of congenital rubella syndrome (CRS) or congenital rubella infection only associated with the administration of the rubella vaccine RA27/3 during pregnancy. METHODS: To classify the prevaccination maternal immune status, a serum sample was taken at the initial evaluation to detect IgM and IgG rubella antibodies (enzyme-linked immunosorbent assay). All pregnancies were followed up and all newborns were evaluated. A cord serum sample of their children was taken at birth. We calculated odds ratio, OR (95% confidence interval, 95% CI) associated with miscarriage, stillbirth, prematurity, low birth weight, and the presence of defects compatible with CRS. RESULTS: The prevaccination immune status was established in 797 women and 1191 mother and child pairs were analyzed. Adjusted OR for miscarriage (OR = 0.60, 95% CI = 0.26-1.39), stillbirth (OR = 1.32, 95% CI = 0.10-16.81), prematurity (OR = 0.25, 95% CI = 0.03-2.39), low birth weight (OR = 0.25, 95% CI = 0.03-2.23) and defects compatible with CRS (OR = 1.09, 95% CI = 0.34-3.54) showed no association between immune and susceptible maternal status. There were no cases of CRS and no children were IgM positive. CONCLUSIONS: No adverse pregnancy outcome such as miscarriages or CRS was documented in women who were vaccinated and unknowingly pregnant. These results support RA27/3 rubella vaccine safety.     

Congenital rubella syndrome in Western Australia

The birth prevalence of congenital rubella syndrome (CRS) in Western Australia has been around 20 per 10 000 live births with peaks up to 100 per 10 000 in rubella epidemic years. The rate appears to be falling but it is still too soon to know whether the rubella vaccination programme in Western Australia has made a significant impact. The cohorts of young women who would have received the schoolgirl vaccination programme are only now entering the child bearing age groups. Observed falls may be due also to delayed diagnosis particularly of cases of deafness only. The proportion of nonimmune young women who would have been eligible for the programme in one maternity hospital has fallen. This study needs to be repeated to ascertain whether further epidemics of rubella have resulted in peaks of CRS or whether the vaccination programme has started to have an effect.

Abstract The birth prevalence of congenital rubella syndrome (CRS) in Western Australia has been around 20 per 10 000 live births with peaks up to 100 per 10 000 in rubella epidemic years. The rate appears to be falling but it is still too soon to know whether the rubella vaccination programme in Western Australia has made a significant impact.

Observed falls may be due also to delayed diagnosis particularly of cases of deafness only. The proportion of nonimmune young women who would have been eligible for the programme in one maternity hospital has fallen.
This study needs to be repeated to ascertain whether further epidemics of rubella have resulted in peaks of CRS or whether the vaccination programme has started to have an effect.     

An epidemic of congenital rubella in Barbados

Rubella and congenital rubella syndrome (CRS) are preventable, but epidemics of rubella and CRS are not infrequent in the Caribbean and other developing countries. As a result of a surveillance system initiated after an epidemic of rubella in the Barbadian population in 1996, cases of CRS were identified and investigated. A total of seven cases of CRS were proven to be rubella IgM-positive. The infants were found to have a mean birthweight of 2587 g and a mean gestational age of 38 weeks. The clinical course, complications and outcome of those infants were documented and the cost of acute hospital care for each patient was also recorded. Cataracts in four infants, congenital heart disease in three and central nervous system abnormalities in five were the major clinical abnormalities. In four infants, two or more clinical systems were affected. The combined total hospital stay was 105 days (mean 15, range 0-44). A national effort to immunize all those at risk and a strict surveillance programme are essential to prevent future epidemics. This would lead to a significant reduction in the number of cases of rubella and CRS and could effect substantial savings in the national health budget.     

Molecular epidemiology of rubella virus in Asia: Utility for reduction in the burden of diseases due to congenital rubella syndrome

BACKGROUND: Rubella is a mild disease mainly of infants, involving a rash and a fever. However, when women who have no immunity to rubella are infected during the early stage of pregnancy, their babies are often born with congenital rubella syndrome (CRS), which is characterized by a few disorders including deafness, cataracts and heart malformations. To prevent CRS, several strains of live attenuated rubella vaccine have been developed and introduced into immunization programs in many countries. In most Asian countries except Japan, Singapore and Taiwan, rubella remains uncontrolled, and the burden of diseases from CRS is high. In order to develop a control program to reduce the number of CRS cases in Asian countries, it is necessary to conduct a survey of rubella and CRS cases, and to then determine the genotype of the circulating rubella virus in each country. METHODS: Cases of rubella and CRS, based on national reporting systems or active surveillance in the Asian countries, are summarized. Sequences of the E1 gene of the virus isolates from the Asian countries were compared by phylogenic analysis. RESULTS: Recent studies of the molecular epidemiology of rubella virus worldwide revealed that there are two genotypes, and that genotype I is circulating almost worldwide, while genotype II is an Asian prototype restricted to the Asian continent. Genotype I viruses fall into a number of groups, some of which are geographically localized. Antigenically these two genotypes are cross-reactive and immunization with either virus results in immunity to all rubella viruses. DISCUSSION: The hypotheses that rubella virus has evolved on the Asian continent is proposed. The World Health Organization (WHO) has recognized that a rubella immunization program can be combined with the measles immunization program. Inclusion of rubella in the expanded program of immunization (EPI) of measles would be ideal in Asian countries, as it would be efficient and cost effective to administer one injection containing a three-combined vaccine (MMR). It would also be desirable given that WHO require laboratory tests to confirm the presence of measles or rubella as part of it's measles control project, because rubella is often misdiagnosed as measles.     

Congenital ocular blindness in children, 1945 to 1984

A total of 676 children born in British Columbia with congenital ocular blindness during the years 1945 through 1984 were studied. The birth prevalence rate of congenital blindness has decreased from eight per 10,000 live births in the late 1940s to three per 10,000 live births. Retinopathy of prematurity was replaced by genetic ocular disorders as the leading cause of congenital blindness, although the former is reemerging. The rate of congenital rubella infection also declined. There has been a significant increase in the rate of births with optic nerve lesions during the past 15 years, while the rate of births with lesions of the lens fell, reflecting the decline in the rate of maternal rubella infection. There are fewer children with congenital ocular legal blindness who have no light perception today, and they also have fewer associated handicaps.     

Very low birth weight preterm infants with early onset neonatal sepsis: the predominance of gram-negative infections continues in the National Institute of Child Health and Human Development Neonatal Research Network, 2002-2003

BACKGROUND: Early onset neonatal sepsis (EOS, occurring in the first 72 hours of life) remains an important cause of illness and death among very low birth weight (VLBW) preterm infants. We previously reported a change in the distribution of pathogens associated with EOS from predominantly gram-positive to primarily gram-negative organisms. OBJECTIVE: To compare rates of EOS and pathogens associated with infection among VLBW infants born at centers of the National Institute of Child Health and Human Development (NICHD) Neonatal Research Network during 3 time periods: 1991-1993; 1998-2000; and 2002-2003. STUDY DESIGN: Prospectively collected data from the NICHD Neonatal Research Network VLBW registry were retrospectively reviewed. Rates of blood culture confirmed EOS, selected maternal and infant variables and pathogens associated with infection were compared between 2002-2003 and 2 previously published cohorts. RESULTS: During the past 13 years, overall rates of EOS have remained stable (15-19 per 1000 live births of infants 401-1500 g). More than one-half of early infections in the 2002-2003 cohort were caused by gram-negative organisms (53%), with Escherichia coli the most common organism (41%). Rates of group B streptococcal infections remain low (1.8 per 1000 live births). Between 1991-1993 and 1998-2000, there was a significant increase in rates of E. coli infections; but in 2002-2003, there was no significant change (7.0 per 1000 live births). Infants with EOS continue to be at significantly increased risk for death compared with uninfected infants. CONCLUSION: EOS remains an uncommon but important cause of morbidity and mortality among VLBW infants. Gram-negative organisms continue to be the predominant pathogens associated with EOS.     

A Rubella Epidemic in Sasebo, Japan in 1957, with Various Complications

Though the rubella vaccination programme for adolescent girls was introduced in Japan in 1977, rubella epidemics have occurred repeatedly. Also in Sasebo, Japan in 1987, we experienced various complications as follows: encephalitis (five cases), meningitis (three), thrombocytopenic purpura (four), vascular purpura (four), hemolytic anemia (two), pneumonia (eight), protein-losing gastroenteropathy (one), multiple organ disorder with encephalitis, purpura, myocarditis, hepatic and renal dysfunction (one), and congenital rubella syndrome (CRS: three). Disorders ranging over multiple organs seem to occur in acquired as well as congenital rubella infection. The incidence of encephalitis was estimated to be 1: 1600 cases of rubella and two of five cases were apparently serious. Though the strategy for preventing rubella has been directed only against CRS, we should note the various and severe complications with acquired rubella infection, and should adopt two-stepped protection: vaccination of young children of both sexes and of adolescent girls.     

Congenital rubella syndrome with death from interstitial pneumonia

There was a rubella epidemic in Japan in 2012–2013, which led to an increased number infants being born with congenital rubella syndrome (CRS). Symptoms of CRS are varied and include cataracts, congenital heart disease, and hearing impairment, but case reports of CRS complicated by interstitial pneumonia are rare. We report the case of a patient with CRS who died of respiratory failure caused by interstitial pneumonia. Thrombocytopenia had been present for approximately 1 month after birth, and the patient presented with sudden lung hemorrhage at 64 days old. Thereafter, respiratory condition deteriorated, and the patient died at 107 days old. Given that infants with CRS who have thrombocytopenia and interstitial pneumonia have a high risk of death, they should be monitored carefully for potential complications.     

Infection and neonatal meningitis: epidemiology, pathogen spectrum, therapy

Data from 196 infants were analyzed who had been treated for neonatal septicemia and/or meningitis between 1962-1974 (n = 88) and 1975-1985 (n = 108). In addition to an increase in the incidence of septicemia (1962-1974: 0.88 cases/1000 live births/year; 1975-1985: 1.8 cases/1000 live births/year) there was also a change in the pattern of infection. Group B streptococcal infections were first observed in 1975. Infections with Escherichia coli increased (1962-1974: 0.25 cases/1000 live births/year; 1975-1985: 0.65 cases/1000 live births/year). Although the incidence of meningitis was similar in both periods (1962-1985: 0.45 cases/1000 live births/year) the relative number of cases declined (1962-1974: 51 of 88 patients; 1975-1985 25 of 108). Mortality also decreased during the second period (1962-1974: 53%; 1975-1985: 29%). All infants were primarily treated with a combination of ampicillin and gentamicin. The decision to discontinue this therapy was based on the clinical course of the patient and the results of culture and susceptibility studies. Ampicillin and/or gentamicin were effective in vitro against all microorganisms which caused septicemia and/or meningitis within the first four days of life. In contrast this antimicrobial combination was only active in vitro against 77% of the pathogens isolated after this time period.     

Prevalence of congenital anomalies in five British regions, 1991-99

AIMS: To describe trends in total and live birth prevalence, regional differences in prevalence, and outcome of pregnancy of selected congenital anomalies. METHODS: Population based registry study of 839,521 births to mothers resident in five geographical areas of Britain during 1991-99. Main outcome measures were: total and live birth prevalence; pregnancy outcome; proportion of stillbirths due to congenital anomalies; and secular trends. RESULTS: The sample consisted of 10,844 congenital anomalies, giving a total prevalence of 129 per 10,000 registered births (95% CI 127 to 132). Live birth prevalence was 82.2 per 10,000 births (95% CI 80.3 to 84.2) and declined significantly with time. The proportion of all stillbirths with a congenital anomaly was 10.5% (453 stillbirths). The proportion of pregnancies resulting in a termination increased from 27% (289 cases) in 1991 to 34.7% (384 cases) in 1999, whereas the proportion of live births declined from 68.2% (730 cases) to 58.5% (648 cases). Although similar rates of congenital anomaly groups were notified to the registers, variation in rates by register was present. There was a secular decline in the total prevalence of non-chromosomal and an increase in chromosomal anomalies. CONCLUSIONS: Regional variation exists in the prevalence of specific congenital anomalies. For some anomalies this can be partially explained by ascertainment variation. For others (neural tube defects, diaphragmatic hernia, gastroschisis), higher prevalence rates in the northern regions (Glasgow and Northern) were true differences. Live birth prevalence declined over the study due to an increase in terminations of pregnancy.     

Burden of congenital rubella syndrome (CRS) in India: <Emphasis Type="Italic">A systematic review</Emphasis>

Background

Rubella, though a mild, vaccine-preventable disease, can manifest with severe teratogenic effects in the fetus labeled as congenital rubella syndrome (CRS) due to primary maternal rubella infection. Despite a reduction in disease burden of several vaccine-preventable diseases through childhood immunization, CRS continues to account for preventable severe morbidity including childhood blindness, deafness, heart disease, and mental retardation.

Objective

To conduct a systematic review to describe the prevalence of CRS and its contribution to major long-term handicaps in Indian population. Another objective was to estimate the susceptibility to rubella infection in Indian adolescent girls and women of reproductive age-group. We also explored strategies to decrease CRS in India by identifying the immunogenicity of rubella containing vaccines (RCV) in Indian children and women, as well as their coverage in India.

Methods

Publications reporting ‘CRS prevalence in general population as well as selected subgroups i.e., suspected intra-uterine infection, congenital ocular abnormalities, deafness, congenital heart disease, mental retardation, and congenital malformations’, ‘seroprevalence to rubella (IgG) amongst women and adolescents’, and ‘immunogenicity and coverage of RCVs’ in Indian population were retrieved through a systematic search. Primary databases employed were Medline through PubMed and IndMed, websites of the WHO, and UNICEF. No restrictions were applied in terms of study designs. The primary outcome measure was ‘congenital rubella syndrome’ (CRS) which was further categorized as ‘suspected CRS’ and ‘confirmed CRS’ as defined by World Health Organization (WHO).

Results

Comprehensive evidence about the true burden of CRS in India is not available. Almost all studies have been done in institutional/hospital set-ups and community-based studies are grossly lacking. There are no studies assessing the prevalence of CRS in general population. All studies have evaluated the CRS burden in symptomatic cohorts of children. 1–15% of all infants suspected to have intra-uterine infection were found to have laboratory evidence of CRS. About 3–10% of suspected CRS cases are ultimately proven to have confirmed CRS with the aid of laboratory tests. CRS accounts for 10–15% of pediatric cataract. 10–50% of children with congenital anomalies have laboratory evidence of CRS. 10–30% of adolescent females and 12–30% of women in the reproductive age-group are susceptible to rubella infection in India. RCVs are highly immunogenic in Indian adolescents and women. The coverage data of RCVs in India is not available. However, the coverage of MMR vaccine has been reported as 42%, 30% and 5% from Delhi, Chandigarh and Goa, respectively.

Conclusion

This systematic review identifies and explores factors associated with the prevalence of CRS in India. There is a need for urgent action in terms of revamping the national immunization policy and introduction of RCVs in the national immunization program. Active surveillance of rubella and CRS is needed to redress the burden of CRS in India.

     

Congenital rubella syndrome despite repeated vaccination of the mother: a coincidence of vaccine failure with failure to vaccinate

Braun C, Kampa D, Fressle R, Willke E, Stahl M, Haller O. Congenital rubella syndrome despite repeated vaccination of the mother: a coincidence of vaccine failure with failure to vaccinate. Acta Pzdiatr 1994;83:674–7. Stockholm. ISSN 0803–5253
Congenital rubella syndrome occurred in a boy born to a mother who had been properly vaccinated three times before conception, but developed only low titers of rubella antibody. The non-vaccinated father most likely infected the mother on a home visit during the third to fifth weeks of gestation. He served in the army and fell ill during an outbreak of a rubella-like disease in his military unit. The mother subsequently developed a slight rash, but rubella IgM antibodies were lacking and rubella infection was not suspected. This incidence demonstrates the necessity of vaccinating all children, including boys and young men. in order to reduce the number of infections and prevent further cases of congenital rubella syndrome.     

A profile of mothers giving birth to infants with congenital rubella syndrome. An assessment of risk factors

To formulate strategies for elimination of congenital rubella syndrome, it is important to identify risk factors for delivering an infant affected by it. We analyzed cases of congenital rubella syndrome in infants born from 1970 to 1985 and reported to either one of two independent Centers for Disease Control surveillance systems. Mothers of infants with congenital rubella syndrome identified in both surveillance systems were disproportionately younger than mothers giving birth in the United States. The risk for delivering an infant with congenital rubella syndrome was approximately 2.5 times higher for blacks compared with whites for both reporting systems. A total of 18% of infants with congenital rubella syndrome born since 1979 were Hispanic (national population average, 7%). Both surveillance systems showed that, although primiparous mothers were at highest risk, 39% of women delivering infants affected by congenital rubella syndrome had had at least one previous live birth, suggesting that postpartum immunization could have prevented these congenital rubella syndrome cases. Young, black, and Hispanic primiparous women represent populations at elevated risk for delivering a congenital rubella syndrome-affected infant and should be specifically targeted for immunization.     

Prevalence, causes, and outcome at 2 years of age of newborn encephalopathy: population based study

OBJECTIVES: To ascertain the prevalence of newborn encephalopathy in term live births, and also the underlying diagnoses, timing, and outcome at 2 years of surviving infants. DESIGN: Population based observational study. SETTING: North Pas-de-Calais area of France, January to December 2000. PATIENTS: All 90 neonates with moderate or severe newborn encephalopathy. RESULTS: The prevalence of moderate or severe newborn encephalopathy was 1.64 per 1000 term live births (95% confidence interval (CI) 1.30 to 1.98). The prevalence of birth asphyxia was 0.86 per 1000 term live births (95% CI 0.61 to 1.10). The main cause of newborn encephalopathy was birth asphyxia, diagnosed in 47 (52%) infants. It was associated with another diagnosis in 11/47 cases (23%). The timing was intrapartum in 56% of cases, antepartum in 13%, ante-intrapartum in 10%, and postpartum in 2%. In 19% of cases, no underlying cause was identified during the neonatal course. Twenty four infants died in the neonatal period, giving a fatality rate of 27% (95% CI 17% to 36%). Three infants died after the neonatal period. At 2 years of age, 38 infants had a poor outcome, defined by death or severe disability, a prevalence of 0.69 per 1000 term live births (95% CI 0.47 to 0.91). In infants with isolated birth asphyxia, this prevalence was 0.36 per 1000 term live births (95% CI 0.20 to 0.52). CONCLUSIONS: The causes of newborn encephalopathy were heterogeneous but the main one was birth asphyxia. The prevalence was low, but the outcome was poor, emphasising the need for prevention programmes and new therapeutic approaches.     

Epidemiological Surveillance of Congenital Syphilis in Spain, 2000-2010

The characteristics of 67 confirmed congenital syphilis cases reported to the surveillance system in Spain (2000-2010) were analyzed. The incidence rates ranged from 0.00 to 2.23 per 100,000 live births. Median age at diagnosis was 4 days. Hepatosplenomegaly was the most common clinical finding, although almost 60% of the cases were asymptomatic. Missed opportunities for congenital syphilis prevention through antenatal care were identified.     

Hypospadias: Prevalence,birthweight and associated major congenital anomalies

The aim of this study was to determine the prevalence of hypospadias over 24 years in a Danish population and to describe the relation to birthweight and associated major congenital anomalies. It is a population‐based study of all cases (live births, fetal deaths and elective terminations of pregnancy) with hypospadias born in the period 1986–2009 in Funen County and reported to the EUROCAT registry of congenital anomalies. Cases were included only if surgery for hypospadias was performed. 223 cases of hypospadias were registered during the period 1986–2009 with an overall prevalence of 16.9 per 10 000 births. The prevalence was significantly higher in 2000–2009 compared to 1986–1999 (P < 0.001). We found a three times higher occurrence of VLBW (very low birthweight) infants among cases with hypospadias. Infants with isolated hypospadias were more likely to have mild hypospadias (68%) while cases with associated major congenital anomalies were less likely to have mild hypospadias (42%) (P < 0.05). Hypospadias was associated with VLBW and the severity of the defect was related to the presence of major congenital anomalies. The prevalence of hypospadias has increased during the study period. The relation to VLBW could indicate a causal relationship for hypospadias or a shared pathogenic factor.     

The costs of fatal and non-fatal falls among older adults.

OBJECTIVE: To estimate the incidence and direct medical costs for fatal and non-fatal fall injuries among US adults aged >or=65 years in 2000, for three treatment settings stratified by age, sex, body region, and type of injury. METHODS: Incidence data came from the 2000 National Vital Statistics System, 2001 National Electronic Injury Surveillance System-All Injury Program, 2000 Health Care Utilization Program National Inpatient Sample, and 1999 Medical Expenditure Panel Survey. Costs for fatal falls came from Incidence and economic burden of injuries in the United States; costs for non-fatal falls were based on claims from the 1998 and 1999 Medicare fee-for-service 5% Standard Analytical Files. A case crossover approach was used to compare the monthly costs before and after the fall. RESULTS: In 2000, there were almost 10 300 fatal and 2.6 million medically treated non-fatal fall related injuries. Direct medical costs totaled 0.2 billion dollars for fatal and 19 billion dollars for non-fatal injuries. Of the non-fatal injury costs, 63% (12 billion dollars ) were for hospitalizations, 21% (4 billion dollars) were for emergency department visits, and 16% (3 billion dollars) were for treatment in outpatient settings. Medical expenditures for women, who comprised 58% of the older adult population, were 2-3 times higher than for men for all medical treatment settings. Fractures accounted for just 35% of non-fatal injuries but 61% of costs. CONCLUSIONS: Fall related injuries among older adults, especially among older women, are associated with substantial economic costs. Implementing effective intervention strategies could appreciably decrease the incidence and healthcare costs of these injuries.
