Development And Preliminary Psychometric Testing Of The Drake Atrial Electrogram Assessment Survey: Daegas©, Jeanette Drake

Dissertations & Theses (Open Access)

Background: Critical care nurses (CCNs) who care for postoperative cardiac surgery patients need specialty knowledge, for example, knowledge of atrial electrograms (AEGs). An inadequate audit trail exists for psychometric performance of instruments to measure CCN knowledge of AEGs. A 29-item survey previously pilot tested with a convenience sample of CCNs in the Pacific Northwest had a Kuder-Richardson-20 estimate of internal consistency of .75. The survey was revised to 20 items (14 knowledge and 6 AEG interpretation) and named the Drake Atrial Electrogram Assessment Survey (DAEGAS).

Objectives: The study objectives were to assess evidence for content validity (content validity …

Knowledge And Self-Esteem In Individuals With Neurofibromatosis Type 1 (Nf1), Kayla Vaughn

Dissertations & Theses (Open Access)

Neurofibromatosis Type 1 (NF1) is a progressive genetic disorder characterized mainly by café-au-lait macules, Lisch nodules, as well as cutaneous and subcutaneous neurofibromas among other traits. Due to the physical manifestations of the condition, it has been observed that individuals with NF1 have lower self-esteem (SE) when compared to the general population. Additionally, a study published over 20 years ago found that overall knowledge of NF1 was poor in individuals affected with the condition. The goal of our study was to reassess knowledge in this population and investigate whether it is related to SE. A survey comprised of knowledge-based questions …

Hemophilia is a hereditary bleeding disorder which requires lifelong specialized care. A network of Hemophilia Treatment Centers (HTCs) exists to meet the medical needs of patients affected by hemophilia. Genetic counseling services are an integral part of the HTC model of care; however, many HTCs do not have genetic counselors on staff. As a result, the duty to provide these services must fall to other healthcare providers within the HTC. To assess the knowledge and attitudes of these providers we developed a 49 question survey that was distributed electronically to hematologists and nurses at U.S. HTCs. The survey consisted of …

Knowledge And Expectations Of Support People In Prenatal Genetic Counseling Sessions, Michelle A. Mcdougle

Dissertations & Theses (Open Access)

Prenatal genetic counseling patients have the ability to choose from a myriad of screening and diagnostic testing options, each with intricacies and caveats regarding accuracy and timing. Decisions regarding such testing can be difficult and are often made on the same day that testing is performed. Therefore, it is reasonable to consider that the support people brought to an appointment may have a role in the decision-making process. We aimed to better define this potential role by examining the incoming knowledge and expectations of support people who attended prenatal genetic counseling appointments.

Support people were asked to complete a survey …

Knowledge, Attitudes, And Utilization Of Brca Testing Among Obstetricians And Gynecologists, Salma Nassef

Dissertations & Theses (Open Access)

Hereditary breast and ovarian cancer (HBOC) is an inherited cancer syndrome that is associated with mutations in the BRCA1 and BRCA2 genes. Carriers of BRCA mutations, both men and women, are at an increased risk for developing certain cancers. Carriers are most notably at an increased risk to develop breast and ovarian cancers; however an increased risk for prostate cancer, melanoma, and pancreatic cancers has also been associated with these mutations. In 2009 the American Congress of Obstetricians and Gynecologists (ACOG) released a practice bulletin stating that evaluating a patient’s risk for HBOC should be a routine part of obstetric …

Knowledge And Perception Of The Role Of Targeted Ultrasound In Detecting Down Syndrome Among A High Risk Population, Ashley M. Henriksen

Dissertations & Theses (Open Access)

The purpose of this study was to determine the perception and knowledge of targeted ultrasound in women who screen positive for Down syndrome in the first or second trimester, and to assess the perceived detection rate of Down syndrome by targeted ultrasound in this population. While several studies have reported patient perceptions’ of routine ultrasound, no study has specifically examined knowledge regarding the targeted ultrasound and its role in detecting Down syndrome. A targeted ultrasound is a special ultrasound during the second trimester offered to women who may be at a higher-than-average risk of having a baby with some type …

What Is Biomedical Informatics?, Elmer V Bernstam, Jack W Smith, Todd R Johnson

Journal Articles

Biomedical informatics lacks a clear and theoretically-grounded definition. Many proposed definitions focus on data, information, and knowledge, but do not provide an adequate definition of these terms. Leveraging insights from the philosophy of information, we define informatics as the science of information, where information is data plus meaning. Biomedical informatics is the science of information as applied to or studied in the context of biomedicine. Defining the object of study of informatics as data plus meaning clearly distinguishes the field from related fields, such as computer science, statistics and biomedicine, which have different objects of study. The emphasis on data …
