Case Study
C.C. has an 11-year-old child with high functioning autism. She is pregnant with her second child and tells her best friend (a pediatric nurse) that she is considering not allowing her second child to receive immunizations as she believes her first child’s autism was caused by the immunizations. C.C. asks for your opinion regarding her decision (Case Study 9).

Studies have reported that autism may be caused by a substance known as thimerosal.
The statistics show a need for concern and the need for studies on a possible correlation between the administration of immunizations and autism.

Patient or Situation Focused Question
The goal of the query is to determine whether immunizations cause autism in children ranging from one month to six years of age.
Do childhood immunizations contribute to the prevalence of autism in children between the ages of one month to six years?
![Page 5: Kevin Smith, Erin Brogden, Shatarius McGhee. C.C. has an 11-year-old child with high functioning autism. She is pregnant with her second child and tells](https://reader033.vdocuments.us/reader033/viewer/2022042822/56649e835503460f94b8512b/html5/thumbnails/5.jpg)
Targeted Sources
PubMed and CDC were the chosen resources to search for the best available evidence to answer our focused question
PubMed is a government database that provided necessary research evidence for our search, such as the effects of childhood immunizations on autism.
The CDC is also a government site that provided accurate information about immunizations in relation to autism.

The Search
To provide an answer for the focus question, information related to childhood immunizations and autism in children ranging from one month to six years of age was the main point of the search.
Conducting a search within PubMed and Center for Disease Control and Prevention with the specific words such as childhood immunizations, autism, and thimerosal allowed for more closely related information to answer the focus question.

The Search
Problem - We identified our problem as “Do immunizations cause autism?”.
Patient - Our patient is a pregnant woman who already has an 11-year-old autistic child.
Action - We are taking action by providing our patient with education on immunization benefits for children. There is no alternative action.

The Search
Patient Results - The result of our research came from Centers for Disease Control and Prevention, which showed there is no correlation between immunizations and autism (Vaccine Safety 2013).
Level of Evidence - We used the highest level of evidence available to draw our conclusions, which were meta-analyses, systematic reviews and evidence based reviews.

Relevant Evidence
The articles that were found within PubMed and the Centers for Disease Control and Prevention were relevant to our focused question because of the information about vaccines in relation to autism.
![Page 12: Kevin Smith, Erin Brogden, Shatarius McGhee. C.C. has an 11-year-old child with high functioning autism. She is pregnant with her second child and tells](https://reader033.vdocuments.us/reader033/viewer/2022042822/56649e835503460f94b8512b/html5/thumbnails/12.jpg)
Relevant Evidence
The first article in the table is “Autism Spectrum Disorder” which focused on the number of children diagnosed with autism in 2013 (2013).
The second article in the table is “prenatal and infant exposure to thimerosal from vaccines and immunoglobins and risk of autism “ which was a randomized controlled case study (2010).
Then third article from CDC titled “Vaccine Safety” provided detailed information about thimerosal and how it affects vaccinated children (2013).

Course of Action
The main course of action would be patient education on whether childhood immunizations contribute to the prevalence of autism in children between the ages of one month to six years.
The best way to implement patient teaching is by providing videos, pamphlets, brochures, and appropriate verbal teaching to the patient.

The Importance of Patient Teaching
![Page 20: Kevin Smith, Erin Brogden, Shatarius McGhee. C.C. has an 11-year-old child with high functioning autism. She is pregnant with her second child and tells](https://reader033.vdocuments.us/reader033/viewer/2022042822/56649e835503460f94b8512b/html5/thumbnails/20.jpg)
Patient Evaluation
Following patient teaching about autism and immunizations C.C. decided to allow her second child to receive the immunizations.
The client’s child was later evaluated and tested for autism. After testing the client’s child it was determined that her second child had no signs of autism.
![Page 21: Kevin Smith, Erin Brogden, Shatarius McGhee. C.C. has an 11-year-old child with high functioning autism. She is pregnant with her second child and tells](https://reader033.vdocuments.us/reader033/viewer/2022042822/56649e835503460f94b8512b/html5/thumbnails/21.jpg)
Conclusion
According to the research C.C. was informed that it is in the best interest of her child to allow him/her to receive immunizations.
The research information helped determine that thimerosal, which is the questionable substance in vaccines, is not linked to autism (Vaccine Safety 2013).
The research primarily came from Centers for Disease Control and Prevention and additional research articles obtained through PubMeb, which showed there is no correlation between immunizations and autism (Vaccine Safety 2013).
