Introduction:
To plan, implement, and evaluate public health policies, public health surveillance is defined as the continuous, organized collection, evaluation, and comprehension of health-related data. It is also firmly integrated with the timely dissemination of these data to those in charge of prevention and control. Due to the diversity of congenital disabilities and their causes, various prevention strategies are required. These include the prevention of sexually transmitted diseases, legislation governing the management of toxic chemicals (such as specific agricultural chemicals), rubella vaccination, and fortification of staple foods with folic acid, iodine, and other micronutrients. One of the fundamental elements of a national program for preventing and treating birth defects is the implementation of suitable surveillance systems for these conditions.
What Are the Types of Birth Defects Surveillance Programs?
Most birth defect surveillance programs fall into one of two categories:
Population-based examines birth defects in the entire population living in a defined geographic area. Hospital-based examines birth defects in particular hospitals, maternity hospitals, or facilities and whose coverage corresponds to deliveries or hospital admissions in these locations. There are three options to categorize case detection further:
-
Active case-finding, which involves systematic child screening and clinical examination.
-
Passive case-finding occurs when afflicted people can access healthcare facilities and are subsequently identified.
-
Hybrid case-finding approach.
What Are Birth Defects?
Birth defects are structural variations that can affect practically any body area (such as the heart, brain, or foot) and are present at birth. The body's functionality, appearance, or both may be impacted. Mild to severe birth abnormalities are possible. The well-being of each child with a birth defect determines which organ or body component is involved and how much it is impacted. The projected lifespan of a person with a birth defect may or may not be impacted, depending on the severity of the issue and which body component is affected.
What Are the Goals and Objectives of Birth Defect Surveillance?
Epidemiological Objectives:
Epidemiologic data is frequently provided as a goal of congenital disability surveillance programs. This monitoring can identify baseline rates and track trends in birth abnormalities. Monitoring provides quantitative assessments of the disease's scope. By doing so, monitoring programs can spot groups of congenital deformities and act as a mechanism for early identification of sudden spikes in their frequency brought on by introducing both new and old teratogens into the community.
Planning and Prevention Objectives:
Planning and prevention are additional goals of programs for birth defect surveillance. Surveillance data can be used to develop promotion and preventive initiatives and to direct public policies. This is demonstrated using food fortification with folic acid to prevent neural tube abnormalities. The surveillance statistics make it possible to evaluate and track the incidence of neural tube abnormalities before, during, and after the introduction of staple foods' folic acid fortification. These data have been used in many contexts to demonstrate the involvement of folic acid fortification in decreasing neural tube abnormalities and birth prevalence, allowing assessment of the efficiency of folic acid fortification as a preventive measure.
References to Experts and Medical Services:
It is possible to manage the unique requirements of children and their families more effectively by using data gathered from birth defect surveillance programs at the family or individual level. Data from surveillance systems may be used to direct newly discovered infants with birth abnormalities to services such as specialist healthcare, early childhood education, and genetic counseling. As a result, impacted children and their families can quickly access the right services, helping to build referral networks for medical services, neighborhood initiatives, and social assistance.
For kids with birth defects, it is critical to estimate when they will need a variety of interdisciplinary clinics, social assistance, and educational programs. Congenital disabilities surveillance programs can aid in estimating future service demands based on the prevalence of congenital malformations, enabling capacity strengthening to ensure that essential resources will be available and that the right personnel will be available to offer the services.
Why Birth Defects Surveillance Is Beneficial for Other Health-Related Programs?
Birth defects surveillance data are typically connected to essential documents such as birth certificates and demographic and parental survey data such as race and education. Birth defect surveillance information can be linked with other health-related surveillance programs' datasets. For instance, early treatments, hospitalizations, and death certificates are some of them.
Numerous examples of childhood mortality analyses include congenital anomaly registry data due to the impact of congenital disabilities on child morbidity and mortality. These analyses provide an efficient method for tracking children's survival and mortality risks with specific major congenital disabilities, such as congenital heart disease, esophageal atresia, spina bifida, diaphragmatic hernia, and omphalocele.
What Are the Obstacles for Birth Defects Surveillance?
To increase the effectiveness of birth defects programs worldwide, cooperative efforts have to be made to conduct data collecting, coding, and analysis uniformly. The key issue is also how to encourage international cooperation. International collaboration networks are crucial for enhancing birth defect surveillance because they support surveillance initiatives in unaided regions and help comprehend the global epidemiological context of congenital illnesses.
In low and middle-income countries, where maternal nutrition is frequently poor, and women may have been exposed to infection and other teratogens, there is a need to increase birth defect surveillance, prevention, and care. There also needs to be more family planning services available. Birth defect monitoring programs, especially in situations of limited financial resources, can offer a precise figure of the burden of congenital malformations, which can be utilized to promote prevention and care and assess the effectiveness of public policies.
Conclusion:
In conclusion, data gathered through birth defect surveillance programs are used to create frequency data, identify risk factors, promote the growth of relevant research, create preventative measures, organize services, and refer children affected to healthcare, educational, and social supports. Additionally, there is an increased likelihood for birth defect surveillance programs to operate in networks globally, which strengthens their findings. Thus, birth defect surveillance programs are a crucial data source for global public health initiatives.
