Australia: National
Australian Congenital Malformation Monitoring System
History:
The mechanism for national monitoring of birth defects in Australia was established in 1981. The national programme became an associate member of the Clearinghouse in 1982 and full member in 1984. Australia has not contributed national data to the Clearinghouse for the last 2 years. In Australia, the data have been provided to the national program by the state and territory health authorities primarily from their birth defects registers and perinatal data collections. However there are variations among state and territory data collections, in the definitions and classifications used, the duration of collection and the level of ascertainment. Therefore Australia has reviewed the existing system and has undertaken a project to develop a new system. They anticipate the resumption of data contribution to the ICBDSR in the foreseeable future.
Size and coverage:
All births of at least 20 weeks gestation or at least 400 grams birthweight in Australia are covered. In 2005, there were 272,419 births in Australia, an increase of 5.9% from the number reported in 2004.
Legislation and funding:
There is no national legislation requiring the reporting of birth defects at the national level. In some States, notification to their birth defect registry is required as part of their respective Public Health Acts. In some States and Territories, birth defect data is collected as part of another collection, and funding, if any is determined by the jurisdiction. The State and Territory Health Departments report to the AIHW National Perinatal Statistics Unit which is the national data custodian of the congenital anomalies data collection. The current funding for development of a national minimum dataset for the congenital anomalies is from the Australian Health Ministers Advisory Committee.
Sources of ascertainment:
The State and Territory birth defect data collections operate independently and there is enormous variation in the breadth of notification sources and level of ascertainment. Other sources of notification may include death certificates, autopsies, hospital morbidity databases, notification from health professionals, cytogenetic and prenatal screening. At the minimum, State and Territory birth defect registries and perinatal data collections send electronic notification to the central data custodian annually.
Exposure information:
Currently not available.
Background information:
In the absence of national legislation, there is variation in the scope, quality of data and ascertainment between the States and Territories. Under the current development project, Australia is working on development of an agreed national minimum data set for congenital anomalies. It’s program of work also includes the development of clinical definitions for congenital anomalies a review of the scope of the collection and development of a nationally consistant classification system.

Australia: VBDR
Victoria Birth Defects Registry
History:
In 1979 the Commonwealth Government agreed in principle to collect more information about births and birth defects. It was decided that the States would be responsible for setting up their own systems and the Commonwealth would establish a National Perinatal Statistics Unit, to collate information from all the states and provide an overall picture. The Victorian Perinatal Data Collection Unit (VPDCU), established under the Health Act of 1958, operates under the aegis of the Consultative Council on Obstetric and Paediatric Mortality and Morbidity (the Council). One of the fundamental purposes of the VPDCU was the establishment and maintenance of the Victorian Birth Defects Register (VBDR). The VPDCU and VBDR were established in 1982.
Size and coverage:
The VBDR collects information on all birth defects for livebirths, stillbirths and terminations of pregnancy pre 20 wks gestation and children up to 18 yrs of age (irrespective of the age at diagnosis). Approximately 3.8% of babies are born with a birth defect at or after 20 weeks gestation. We also follow up terminations for birth defects before 20 weeks, once these are included the overall prevalence is approximately 4%. Birth defects are notified to the register for those babies/fetus’ who were born in Victoria.
Legislation and funding:
The ongoing maintenance of the VBDR is enshrined in the legislation pertaining to the VPDCU (Health Act 1958) and is an ongoing function of the VPDCU, however notification of birth defects outside the reporting period on the Perinatal Morbidity Statistics form (28 days) is a voluntary process. There is a section for reporting of birth defects on the Perinatal form which is completed at the time of birth. Several measures are taken to ensure the ascertainment of birth defects outside this reporting period which will be specified in ‘sources of ascertainment’. The VPDCU & VBDR are funded by the Department of Human Services (State Government).
Sources of ascertainment:
Perinatal forms (approx 48.8%)
Hospital listings* (aPprox 28.8%)
Perinatal death certificates/autopsy reports (approx 7.8%)
Cytogenetic reports (approx 9.3%)
Maternal & Child Health Nurse (approx 4.2%)
Other professionals/parents (approx 1.1%)
* These include obtaining annual inpatient listings from the two major paediatric teaching hospitals detailing all children up to the age of five years who have been subsequently admitted to these hospitals each year with a birth defect. We also obtain annual listings from specialist clinics at these hospital for all children up to the age of five years who have visited either as an inpatient or an outpatient. This procedure has also been adopted for Monash Medical Centre. Other listings are also received from Newborn Screening Services and Genetic Health Services Victoria.
Exposure information:
No exposure information is available.

Australia: WABDR
Australia Western Birth Defects Registry
History:
The Registry was established in 1980, and is currently located in a teaching obstetric hospital. The objectives of the Registry have always been to establish how often birth defects occur, to conduct research into causes and prevention of birth defects, to provide health professionals and the public with information about birth defects, and to monitor and evaluate screening, treatment and prevention programs.
Size and coverage:
Population-based in the state of Western Australia. 30,000 birth a year, ~6% reported with a birth defect. Birth defects diagnosed prenatally and up to the age of 6 years, in stillbirths, terminations of pregnancy and livebirths are included.
Legislation and funding:
Following a period of short term funding from both Federal and State sources, the Registry is now wholly funded by the Western Australian Department of Health. There are several statutory sources of information (birth, death and hospital data collections), and a large number of voluntary sources. Statutory notification is being considered by the Department of Health.
Sources of ascertainment:
Statutory sources: Midwives’ Notification of Birth Forms (all births over 20 weeks gestation), Death Certificates (perinatal, infant and childhood); Hospital Morbidity (all hospital discharges in Western Australia). Voluntary sources: Maternity and paediatric hospitals, Obstetricians, paediatricians, orthopaedic surgeons, Community and Child Health Nurses, Cytogenetic laboratories, Pathology services (including prenatal screening services), Ultrasound practices Genetic Services, Disability services.
Exposure information:
No exposure information is routinely collected.
Background information:
The data on the Registry are routinely linked to the linked dataset of all births, deaths and hospital admissions for Western Australia. This linkage provides information on variables such as maternal and paternal age, labour and delivery data, and maternal illnesses, for both cases of birth defects (numerators) and all births in Western Australia (denominators). Data from the Registry are provided to the
National Perinatal Statistics Unit for monitoring birth defects in Australia as a whole.

Canada: CCASN
Canadian Congenital Anomalies Surveillance Network (CCASN)
History:
The Programme was started in 1966. The Programme was a full member until 1987, when it became an associate member. The Programme was discontinued as an associate member of the ICBDMS in the early 1990s, and reinstated its associate member status in 1996.
Size and coverage:
This system presently monitors about 330,000 births annually, which captures virtually all births in the 10 provinces and 3 territories of Canada. Live births to 1 year of age and registered stillbirths (a birth weight of greater or equal to 500 grams, or greater than or equal to 20 weeks in pregnancy) were captured until 2000. Since 2001, all data provided by Canadian Institute for Health Information (CIHI) only include a 30 days followup period.
Legislation and funding:
Reporting is based on an agreement between the Canadian Institute for Health Information (CIHI), a non-profit organization, which collects and disseminates data on hospital admission/separation in Canada, and the central registry, which is run and funded by the Public Health Agency of Canada. The Alberta Congenital Anomalies Surveillance System and Med-Echo (Système de maintenance et d’exploitation des données pour l’étude de la clientèle hospitalière) for the province of Québec provide their data separately.
Sources of ascertainment:
Cases from most provinces and territories are ascertained from hospital admission/separation summary records collected by the Canadian Institute for Health Information (CIHI) and Med-Echo. The Alberta Congenital Anomalies Surveillance System provides its own separate provincial data. All data sources had a one year follow-up period until 2000. Since 2001, all data provided by Canadian Institute for Health Information (CIHI) only include a 30 days followup period.
Exposure information:
No exposure information is routinely collected in the central registry.
Background information:
Background information is based on hospital admission/separation summary records from the Canadian Institute for Health Information (CIHI) and Med-Echo. Alberta Congenital Anomalies Surveillance provides its own background information. Interpretation of trends should be done cautiously, since 2001 an increasing percentage of records are being coded using ICD-10 CA and may cause discrepancies from previously used ICD-9 coding. Also, as mentioned previously the variation in the follow-up period is another factor which may alter reporting of trends.

Canada-Alberta: ACASS
Alberta Congenital Anomalies Surveillance System
History:
The Programme began in 1966 as a general Registry for Handicapped Children. This was disbanded in 1980 and continued as a surveillance Programme for live and stillborn infants with congenital anomalies who were born in the Province of Alberta.
Size and coverage:
All live and stillbirths in the province are covered which at present comprises about 40,000 births per year. The definition of stillbirth is 20 weeks or more or 500 grams or more. The vast majority of births occur in hospital (approximately 97%). In 1997 a special fetal congenital anomalies surveillance system was started to include those fetuses with congenital anomalies who were either spontaneously lost prior to 20 weeks or where there was termination as a result of prenatal diagnosis.
Legislation and funding:
Reporting is voluntary. The system is run by members of the Department of Medical Genetics, Alberta Children’s Hospital/University of Calgary reporting to Alberta Vital Statistics and Alberta Health. Funding is from Alberta Ministry of Health.
Sources of ascertainment:
Reports are obtained from physician’s notice of birth, live birth and stillbirth registrations, death registrations and a special congenital anomalies reporting form (CARF) from hospitals. This is based on discharge diagnosis, including readmissions for any reason up to one year of age. Additional sources are speciality clinics, such as medical genetics and cytogenetics laboratories.
Exposure information:
None is routine.
Background information:
Linkage studies are possible with other statistical data from Alberta Health.

Canada: British Columbia
British Columbia Health Status Registry (BCHSR)
Congenital Anomalies Surveillance Programme
History:
The Programme was established in 1952 as the Crippled Children’s Registry. Until 1959 the Programme had an age limit of 21, but this was removed in 1960 and the name was changed to the Registry for Handicapped Children and Adults and included all familial conditions and congenital malformations. In 1975, the Registry’s name was changed to the Health Surveillance Registry as risk registers for amniocentesis, rubella, hyaline membrane disease, and fetal alcohol syndrome were added. In 1991, the Royal Commission Report on Health Care and Costs contained a recommendation that Vital Statistics should develop and maintain a registry of individuals with disabilities to assist in the development of long-range plans and to monitor the changing needs of the population. Subsequently, in September 1992, amendments to the Health Act established the legislative mandate and responsibilities for the HSR. The Registry’s current name, Health Status Registry, was acquired in 1992. In order to refocus the Registry’s emphasis on children, the criteria for registration of individuals with long-term physical, mental and/or emotional problems was restricted to persons under the age of 20 years old, however registration of persons with genetic conditions was not age limited. By 2000 there were approximately 215,000 records in the Registry.
Size and coverage:
The registry covers all births in the province approximately 45,000 births annually including stillbirths with at least 20 weeks gestation or birth weight 500 grams or more.
Legislation and funding:
In 1992, amendments to the Health Act established the legislative mandate and responsibilities for the BC HSR. Funding comes from the British Columbia Vital Statistics Agency.
Sources of ascertainment:
Sources include: Notice of Live and Stillbirth, Death registrations, Hospital Admission/Discharge Abstracts, Children’s Hospital, Sunnyhill Hospital, UBC and Victoria General Medical Genetics Clinics, Child Development Centres, Health Regions, the Asante Centre for Fetal Alcohol Syndrome.
Exposure information:
Information on complications of pregnancy, labour or delivery is available on Vital Statistics birth registrations and environmental/occupational and drug/alcohol/smoking lifestyle related information can be obtained from the death registrations for the deceased.
Background information:
The registry data are regularly matched to Vital Statistics birth registrations to obtain birth particulars of the registrants and maternal/paternal information, and also matched to death registrations to get the date of death and causes of death if the registered person was deceased. The registry also registers cases of medically terminated pregnancies due to congenital anomalies.

England and Wales
Congenital Malformation Monitoring Programme of England and Wales.
History:
The monitoring Programme was started in 1964. It was a founding member of the Clearinghouse and is a full member.
Size and coverage:
All births in England and Wales are covered, at present approximately 625,000 annually. Stillbirths of 24 weeks or more gestation are registered.
Legislation and funding:
Reporting is voluntary. The governmental Office for National Statistics finances the National Congenital Anomaly System.
Sources of ascertainment:
Reports are mainly based on notifications of births prepared by attendants at birth, either physicians or midwives by means of a paper form (the SD56 form). This form contains a written description of the anomaly and details of the birth, along with some demographic information about the parents. In areas covered by local congenital anomaly registers this information is supplemented by other reports from neonatal intensive care units, special care baby units etc.
It has long been recognised, however, that there is under reporting in NCAS. Therefore NCAS has embarked on an on-going programme of improving the level of reporting to the system. Since 1998, local congenital anomaly registers have begun to provide data to NCAS in each of the years detailed below:
1998 CARIS (Wales)
1999 East Midlands & South Yorkshire Congenital Anomaly Register
2000 North Thames (West) Congenital Malformation Register
2000 Merseyside and Cheshire COngenital Anomaly Survey
2002 Wessex Antenatally Detected Anomalies Register (WANDA)
2002 Congenital Anomaly Register for Oxfordshire, Berkshire & Buckinghamshire
(Oxforshire only prior to 2004)
2003 Northern Congenital Abnormality Survey
2003 South West Congenital Anomaly Register
In 2004, congenital anomaly notifications are now received for all births in Wales and 45 per cent of births in England. For areas for which NCAS relies solely on SD56 notification forms recording is likely to be less complete. Reports of terminations of pregnancy have been compiled from notifications of abortions that are completed by the operating practitioners under the 1967 Abortion Act and are sent to the Chief Medical Officers of England and Wales. The tables sent to the International Clearinghouse only include notifications of abortions performed under Grounds E of the Act. An abortion may be performed under Grounds E if ‘there is substantial risk that if the child were born it would suffer from such physical or mental abnormalities as to be seriously handicapped’. Since April 2002, the Department of Health has been responsible for the processing of the abortions notification forms and information has been made accessible to the Office for National Statistics (ONS) for statistical purposes.

Spain: ECEMC
Spanish Collaborative Study of Congenital Malformations (ECEMC)
History:
The programme was created in 1976 by Prof. Dr. María Luisa Martínez-Frías, as a hospital-based case-control study and surveillance system. It contributes to EUROCAT with data since 1980. In January 2002 the ECEMC Programme became integrated into the CIAC (Research Center on Congenital Anomalies), of the Instituto de Salud Carlos III (ISCIII) from the Ministerio de Sanidad y Consumo of Spain and since last year from the Ministerio de Ciencia e Innovación. It is also directed by Prof. Martínez-Frías. In 2006 the ECEMC was recognized as an excellence Research programme to be integrated into the CIBERER (Centre for Biomedical Research on Rare Diseases). The ECEMC has 2 Teratogen Information Services since 1991, one for the general population and another one for physicians.
Size and coverage:
Data are obtained from about 70 hospitals distributed all over Spain. The annual number of births surpasses 100,000, representing more than 21% of all Spanish births. Stillbirths of at least 24 weeks or 500 g. have been included since 1980. Data on terminations of pregnancy due to the presence of congenital anomalies, which can be legally performed within the first 22 weeks of gestation, can only be gathered in some participating hospitals.
Legislation and funding:
It is a research programme with voluntary participation of hospitals (but mandatory subjugation to the Operating Rules for those participating), and is financed mainly by the Spanish Administration and, partially, by non-governmental organisations.
Sources of ascertainment:
The detection period is the first 3 days of life, including major and/or minor/mild defects. The information comes from delivery units and paediatric departments of the participating hospitals. Mothers are interviewed directly by the participating physicians, during those first 3 days after infant’s delivery, to fill in the ECEMC standard protocols, which include more than 300 data for each child, whether case or control. The information for each case and its control is gathered by the same physician. Controls are defined as the next non-malformed infant born at the same hospital that the case with the same sex as the malformed infant. In many instances, photographs, imaging studies, high-resolution bands karyotypes and molecular analysis when needed (which are performed at the central group of the ECEMC), and other complementary studies are available. Biological samples are also stored in the ECEMC registry for those cases for which the collaborating physicians send them, with the informed consent of the parents.
Exposure information:
The mother of each reported infant (case or control) is interviewed within the first three days after delivery to obtain data on several exposures (parental occupation, maternal acute or chronic diseases, drug usage, illicit drugs, alcohol and tobacco maternal consumption, exposure to other chemical or physical factors), apart from the other data gathered (family history, obstetrical and demographic data, among others). It is important to note that when the pediatricians detect the cases and select the control children, they are blinded to the different maternal and family data that they are going to collect.
Background information:
Total number of births by sex and number of twin pairs in each participating hospital are gathered. Other background information is obtained from the control material.

UK Wessex: WANDA
Wessex Antenatally Detected Anomalies Register
History:
The Registry was formally established in 1994, and is located in the Clinical Genetics Department of the teaching hospital in Southampton. The focus of the register is antenatal and includes all fetuses suspected to have a congenital anomaly. All babies born with an anomaly, potentially detectable antenatally, are also included. There is no limit to the age at which cases may be reported, but in reality few cases are registered after the neonatal period. The link with Genetics, however, ensures the inclusion of all unbalanced chromosome errors, whenever detected. The term ‘congenital anomaly’ is used here in its widest sense and includes chromosome errors, inborn errors of metabolism and syndromes where a gene mutation has been identified. With the clinical perspective to this register, multidisciplinary meetings are held on a regular basis in each district covered. At these, all cases that have arisen in the intervening time period are discussed and management issues addressed. In addition, feedback from the register is used to inform local policies.
Size and coverage:
The Register is population based with approximately 27,000 deliveries per year and covers all births in the old Wessex region, Jersey and Guernsey. All miscarriages, stillbirths, TOPFAs and live births are included where an anomaly has been diagnosed.
Sources of Ascertainment:
Reporting is voluntary and multisource and includes sonographers, radiologists, obstetricians, midwives, paediatricians, paediatric surgeons, paediatric cardiologists, geneticists, genetics laboratories and pathologists.

The approach of the register is to focus on collecting data that is reliably available and so relatively complete. This includes maternal and child demographics, full antenatal findings, test results and the postnatal findings and diagnosis. This may include family history and maternal health and medications but data on the father are not kept unless relevant to the diagnosis of the fetus/child.

USA-Atlanta: MACDP
Metropolitan Atlanta Congenital Defects Program
History:
The Programme started in 1967 and was a founding member of the ICBDSR. The Programme is a full member of the ICBDSR. Size and coverage: The Programme covers all births within a five-county area in metropolitan Atlanta, Georgia. The annual number of births in this area is approximately 50,000. Stillbirths and terminations of at least 20 weeks gestation are included. Elective terminations at any gestational age are included.
Legislation and funding:
In 1994 the Georgia Department of Human Resources (GDHR) added birth defects to the list of legally reportable conditions in Georgia. In 1997 the GDHR authorised the Birth Defects Branch at the Centers for Disease Control and Prevention (CDC) to act with and on its behalf to collect health information on children with birth defects. The Programme is funded by the Centers for Disease Control and Prevention.
Sources of ascertainment:
Multiple sources, such as delivery units, paediatric departments, neonatal intensive care units, laboratories, prenatal diagnostic centres and tertiary care centres, are used to ascertain malformed infants born in the defined area with a follow-up to age six years.
Exposure information:
Exposure information is obtained by interview for mothers of reported malformed infants who participate in various research projects.
Background information:
Number of live births and demographic information on the five counties are obtained from vital statistics.

USA-California
California Birth Defects Monitoring Program
History:
The California Birth Defects Monitoring Program was established in 1983 to monitor rates and trends and conduct epidemiological investigations to find causes of birth defects. The Program has had both state and federal funding, and is a branch of the California Department of Public Health, within the Maternal, Child and Adolescent Health Division. The Program is an associate member of the Clearinghouse.
Size and coverage:
The Program operates a population-based registry among approximately 223,000 births. The registry includes 12 counties whose birth defects rates and trends are representative of California which reflect the state’s racial/ethnic diversity.
Legislation and funding:
The Program operates under statutory authority: Health and Safety Code Sections 103825-103855. The Program has received money from these sources in the past: Federal Block Grant Funds from Title V, State General Fund, and special funds from the Prenatal Genetic Disease Screening Program. Since July 2009, only Title V funding remains for the Registry.
Sources of ascertainment:
Staff actively ascertain data at hospitals and genetic centers by reviewing logs and identifying children with structural birth defects generally encompasses within BPA 740-759, diagnosed prenatally through age one. All diagnostic information is abstracted direct from medical records; registry files are cross-linked with vital statistics data to verify demographic information.
Background information:
Registry data, a description of Program activities, research findings, and publications are available at www.cdph.ca.gov

USA-Texas: BDES
Texas Birth Defects Epidemiology and Surveillance Branch
History:
BDES was established after an unusual cluster of anencephaly cases that occurred in Brownsville, Texas in 1991. Epidemiologic investigations revealed a higher than expected rate of neural tube defects among children born to Hispanic mothers living in South Texas. In recognition that epidemiologic resources are routinely needed to investigate birth defects clusters, the Texas State Legislature passed the Texas Birth Defects Act in 1993, which authorized the establishment of BDES. Since 1994, BDES has maintained the Texas Birth Defects Registry, an active population-based birth defects surveillance system, which has been statewide since 1999. Through multiple sources of information, the Registry monitors all births in Texas and identifies cases of birth defects. Children identified through the Registry are referred to appropriate medical and community services. In 1996, the CDC-funded Texas Center for Birth Defects Research and Prevention was established under the auspices of BDES . The Programme is a full member of the ICBDSR.
Size and coverage:
The Programme covers all deliveries to mothers residing in Texas (approximately 380,000 annually). Stillbirths and terminations of any gestational age are included. Cases diagnosed up to age one are included (up to any age for fetal alcohol syndrome). As of 2006, there were over 100,000 birth defect cases in the Registry.
Legislation and funding:
Birth defects surveillance was mandated by the Texas Birth Defects Act in 1993, and is codified in the Texas Health and Safety Code Chapter 87. About one-half of funding for the birth defects registry is from state general revenue with the remainder from federal block grants.
Sources of ascertainment:
Birth hospitals, birthing centres, lay midwives, hospitals where affected children are treated.
Exposure information:
Limited information on maternal illnesses and conditions, limited information on maternal exposures such as medications.
Background information:
Basic demographics, reproductive history, gestational age, delivery information.

USA-Utah: UBDN
Utah Birth Defects Network (UBDN)
History:
The Utah Birth Defect Network (UBDN) began in 1994 monitoring neural tube defects, expanding its identification of major malformations through 1999 when all major structural birth defects were identified. The program is a full member of the ICBDSR.
Size and coverage:
The UBDN is state wide population based surveillance system covering approximately 50,000 births annually. Stillbirths and terminations of at least 20 weeks gestations are included. Terminations less than 20 weeks are included for all major birth defects. Currently a pilot is ongoing to incorporate metabolic disorders (identified by newborn screening) into surveillance.
Legislation and funding:
In 1999, an Administrative Rule was enacted under the Utah Health Code Statute which mandates all delivery hospitals and laboratories to report any pregnancy or infant diagnosed with a birth defect. This administrative rule also covers health care providers and other agencies that voluntarily report a birth defect case to the UBDN. The UBDN has additional projects being funded from several sources and includes Maternal Child Health and CDC grants.
Sources of ascertainment:
Multiple sources (n=128), such as delivery units, paediatric departments, laboratories, prenatal diagnostic centers, hospital discharge data, other specialties, and champions are used to ascertained malformed infants born in Utah. These sources include reports that are generated by the facilities, case reports submitted by individual care providers, as well as reports actively obtained by UBDN staff reviewing records or log books.
Exposure information:
Basic risk factors including medications taken during pregnancy, infections, chronic conditions are all recorded based on medical records abstraction.
Background information:
General Detailed background information including demographics, reproductive history, gestational age, prenatal diagnostics, and family history are all collected from the medical record. The number of births and basic demographic data are obtained from vital statistics.

Wales: CARIS
Congenital Anomaly Register and Information Service
History and Funding:
Data collection commenced on 1st January 1998 and includes any baby where pregnancy ended after this date. CARIS joined EUROCAT in 1998 and ICBDSR in 2004. CARIS is based at Singleton Hospital, Swansea and is funded by the National Assembly for Wales. CARIS aims to collect data which can be used to describe the pattern of congenital anomalies across Wales. This should help:
Build up and monitor the picture of congenital anomalies in Wales
Assess interventions intended to help prevent or detect congenital anomalies
Plan and co-ordinate provision of health services for affected babies and children
Assess possible clusters of birth defects and their causes.
Population Coverage: The Registry covers the entire country of Wales (population-based = All mothers resident in defined geographic area) with an annual number of births of around 32,000.
Sources of Ascertainment:
Reporting is voluntary. The Register relies upon multi-source reporting including: antenatal clinics, delivery units, pediatric departments, ophthalmology, cytogenetics, pathology, orthopaedics, maxillo-facial and regional centres of pediatric surgery. Each delivery unit has a nominated co-ordinator to help ensure good reporting and chase for further details. CARIS staff also visit units to help with data collection. Registration covers all fetuses with prenatally diagnosed anomalies. There is no lower age of cut off, so the fetal losses and early terminations with anomalies are registered. All liveborn babies with structural anomalies are registered if diagnosed before their 1st birthday, but all chromosomal anomalies are registered, even if diagnosed later. Data exchange with the Mersey Register is also important as babies needing specialist services in North Wales are referred to Liverpool.
Termination of Pregnancy: Termination of pregnancy is legal up to 24 weeks of gestation. Terminations of pregnancy are registered. If congenital anomaly is diagnosed, there is no upper gestational age limit for termination in cases of major anomaly.
Stillbirth Definition and Early Fetal Deaths: Stillbirth definition: 24 weeks gestation (late fetal death after 23 completed weeks of gestation). Stillbirths of 24 weeks or more gestation are registered. Early fetal deaths/spontaneous abortions have no lower limit for inclusion on the register (earliest recorded go down to 8 weeks gestation). Autopsy rates were not given.
Exposure information:
Information on maternal drug use, maternal and paternal diseases and occupations, outcomes of previous pregnancies is available. Folic acid supplementation before and during pregnancy is also collected.
Denominators and Controls Information: Denominator date is obtained from the Office for National Statistics.
