Healthcare scientists usually carry out a variety of clinical tests in order to obtain accurate and reliable results. In order to introduce new tests into this routine, we must first determine the sensitivity and specificity of the potential test. Sensitivity is the ability of a test to identify true positives within a population. In a clinical setting, the sensitivity of the test determines its ability to correctly identify a patient with a disease. This can be displayed as a formula: Sensitivity=True positives/True Positives+ False negatives True positives are the number of patients within a given population that are correctly diagnosed with having the disease while false negatives are the patients within the same population that have the disease …show more content…
The same concept of percentage applies to specificity as seen in sensitivity where 100% specificity indicates that a test is able to identify all the true negatives within a population. Therefore a decrease in specificity increases the number of people who are diagnosed with the disease but are in fact false positives. Linearity of a test method is its ability (within a given range) to obtain results directly proportional to the concentration of the analyte in the sample. This can be seen during a series dilution where each dilution should have a direct proportion to the concentration or during a first order chemical reaction. Linearity can be used to conduct a calibration verification where a mock sample with a known concentration containing martials commonly found in a patient sample are used to prove that the test/instrument is properly calibrated throughout the reportable reference range of patient
D1: I have decided to look at a 6 year old going through bereavement. Bereavement means to lose an individual very close to you. When children go through bereavement they are most likely to feel sad and upset about the person’s death. Children at a young age may not understand when a family member dies. Children may not understand bereavement. For example a 6 year old’s father been in a car crash and has died from that incident. Death is unpredictable and children can’t be prepared for a death of a family member as no one knows when someone is going to die or not. Unfortunately every child can experience bereavement even when a pet dies. It is important that we are aware that effects on the child so we can support them in the aftermath.
What does ‘care’ mean? Care is the provision of what is necessary for your health, welfare and protection of someone or something. However when you talk about ‘care’ in a care practice the term changes and becomes more about enabling people to meet all their needs which would refer to their social, physical, emotional, cognitive and cultural needs. The individual is central to the meaning of care in this context.
... susceptibility. Patients who subsequently needed further treatment for coronary heart disease displayed significantly different protein expression as opposed to patients who needed no further treatment. This revolutionary study provides a new way of detecting coronary artery disease that is both cost effective and less dangerous for patients.
Professionalism can be defined as the competence of skills and principles of an individual in a profession. A professional must be knowledgeable in their profession, committed to improvement of one’s knowledge and skills, service oriented, covenantal relationships to patients/patrons, creative, innovative, ethical, accountable and a leader. These competencies are essential for a professional to perform and excel in their profession.
A health care directive is a legal document, based on personal values and beliefs, providing people with a sense of control and independence for their medical care. The purpose of a health care directive is to allow personal wishes on various treatments options to be met, when the individual is presented incapable. Since it is a legal document, health care professionals and family members have to abide with individual’s health care directive. Personally I value autonomy, independence, family, dignity, and selflessness. These core personal values allow me to reflect, fully comprehend and accept the consequences to the health care decisions I make for myself. In conclusion, the sections of the health care directive
Individuality. It implies in regarding them as individual, concentrating on their needs, capacities and accomplishments. It implies esteeming who they are, what they are occupied with and what they can in any case do, not on the way that they have dementia hence needn't bother to have the same attention as normal individual. It is also treating them with respect and dignity.
Most healthcare providers will tell you that they feel that they are called to their profession, and most would tell you that they love practicing in their field of study. Healthcare providers are placed in situations frequently that can lead to cognitive dissonance. In healthcare there is a pressure to perform tasks frequently, timely, perfectly, and in a cost effective manner. This can lead to situations that are in conflict with training as well as with personal ethics.
A health care system exists to address the health care issues of its community. To do so equitably it must recognise, plan for and implement necessary changes to cater for the diverse needs of the community. It is when the community engages in dialogue with the providers of health care that the specific needs are revealed and can then be planned for and implemented. However it is often those who have no voice in the community who have the greatest need of health care. Their lower socio economic status, as well as their lower educational levels, deters them from accessing appropriate health care. Consumer participation is one way to address this lack of representation.
What is point-of-care testing : The healthcare industry is in the midst of a transformative change. It is undergoing reform through initiatives that focus on improving patient outcomes, tying provider reimbursement to quality metrics (rather than traditional fee for services), adopting electronic patient records, and developing accountable care organizations. One of the major enablers of these changes is the proliferation of point-of-care (POC) technologies that offer the promise of improving outcomes and reducing costs through increased access to and use of diagnostic and monitoring solutions. Point-of-care testing is medical diagnostic testing at or near the point of care—that is, at the time and place of patient care. This contrasts with the historical pattern in which testing was wholly or mostly confined to the medical laboratory,
Health literacy plays an important role in individuals’ decision-making. The scope of health literacy does not limit to traditional medical perspective. In fact, it has extended from the basic understanding of diseases and medications to all aspects that affect health. As one of the key social determinants, health literacy has huge impact on health and well-being. Its influence is associated with disease prevention, healthy lifestyle promotion, policy making, etc. This essay will first discuss the concept of health literacy and the consequences that link to it, and then give a strategy—designing user-centred messages in education, to improve health literacy,
Education is neither linear nor static. It requires evolution and fluctuations. I received my undergraduate degree in Exercise Science at UNC Charlotte, and now it is time for a prime conversion to be made. Attending the Masters of Public Health program at UNC Charlotte would open the door for me to pursue my career aspirations in health care. Specifically, I am interested in epidemiological methods in community health. My ambition, perseverance, and work ethic have brought me to a high point, and enrolling in the Masters in Public Health program would raise that threshold even higher.
I believe the most significant moment in the history of British welfare was the birth of National Health Service. The purpose of this essay is to outline the history of the National Health Service and why it was introduced into the everyday lives of the British people. As the National Health Service is a major factor of the welfare given to the people of Britain, we must look at the early years of the Welfare laws and acts passed down through the centuries, which eventually lead to the creation of the NHS. In addition to explore how social policy had an impact on the NHS, the essay will tread the discussion in the context of some of the economic, political and social concepts that influences the development of social policy in the NHS. It also
...ue to numerous medical errors. With the amount of medical errors that currently do occur which is a current health care issue it cost the health care billions of dollar each year to fix the mistakes that were made.
Molecular Diagnostics is defined as tests which identify certain patterns in both RNA and DNA. These tests are able to identify RNA, genes, and protein sequences which play a role in diseases. These sequences may be linked to diseases which include nucleotide polymorphism, deletions, rearrangements, and many more. Molecular Diagnostics is also able to identify and multiply the presence of certain microorganisms and cells. Molecular Diagnostics provides a great amount of clinical information. For example, hereditary disorders to specific drug therapies or hereditary relationships in general. Molecular Diagnostics is also well known for providing qualitative and quantitative results that help in detection,
Health care has always been an interesting topic all over the world. Voltaire once said, “The art of medicine consists of amusing the patient while nature cures the disease.” It may seem like health care that nothing gets accomplished in different health care systems, but ultimately many trying to cures diseases and improve health care systems.
