Answer:
Evidence-based practice to support decision making process and legal ethical and political dimensions of practice
Evidence based practice is a critical element in the decision making process in nursing practice as well as all health care sectors. Evidence based practice involves clear, careful and judicious utilization of best practice or evidence found in literature to provide care and best patient outcome in clinical practice. The provided case study involves a 98-year-old female patient (EB) who presented to the hospital with skin tear in the lower left leg after fall injury. As per NMBA Standard 1.1 and Standard 5.1, the nurse uses best available evidence from literature to provide best available treatment to the patient (Nursingmidwiferyboard.gov.au, 2018). A nurse should use the evidence based practice approach to access, analyze and develop a plan for the treatment course of the patient. The provided case study provided all the necessary information that is required to make a treatment plan for the patient EB. However, if the nurse employs evidence based approach in making the treatment plan for EB, she can obtain all the current evidence of the literature studies that are conducted in relation to the disease in question (DiCenso, Guyatt & Ciliska, 2014). For instance, the provided information states that the patient experienced fall due to pre-syncope episode. In this scenario, the nurse professional can search the literature and find the best and latest evidence regarding the data related to pre-syncope and its relation with fall in elderly patients. The literature information can be also used to make a treatment plan for the patient (Dang & Dearholt, 2017). The literature evidence can help in careful, clear and judicial use of the provided information in favor of the best patient outcome.
Evidence in literature provides the data regarding the best scientific research and rational evaluation of the current practice. The type of evidence can vary depending on the methodologies employed to derive the data, such as quantitative studies, qualitative studies or meta-analysis. Quantitative studies include RCTs and observational studies, whereas qualitative studies involve individual case study reports (ICSR). Meta-analysis includes review of the already published data. Evidence from these literature studies can help in identification of statistical data revealing the number of patients who experienced similar incidents in the past (Dang & Dearholt, 2017). For instance in the provided case study, the nurse professional can obtain the statistical data regarding number of elderly patients who experienced fall injury due to pre-syncope symptoms. Similarly the literature analysis can also give information regarding scientific research conducted in relation to the relationship between both and the current treatment practice as well as diagnostics that are required for making the diagnosis (Melnyk et al., 2014).
EBP has been associated with improved patient outcome, promoting healthy communities and improvement of clinical practice. Literature evidence also includes expert opinion in the form of experiential data. In order to rank the evidence, a rating scale has been developed. However, it can be concluded that no level of evidence rating can eliminate the need of judgement of a clinical expert in decision making, assessment and planning (Storms et al., 2015). In order to use EBP in actual clinical practice, the nurses should collaborate with the physicians, supervising nurses, administrators to ensure the quality of evidence that can be used in actual clinical case scenarios to ensure the integrity of health care system. Employing EBP in the current case study means that the nurse is able to derive information regarding the causes of falls in elderly age group; further the nurse can narrow down the search by adding additional keywords such as medical history of most important risk factors mentioned in the case study e.g. osteoarthritis (Dang & Dearholt, 2017). This will help in the thorough analysis of the complete case scenario of EB(the female patient) as well as in deriving the data regarding any link between the history of osteoarthritis and falls in elderly.
The provided case study elaborates the medical history of the patient. The female patient has a medical history of fall, osteoarthritis, chest pain, spinal stenosis, chronic renal failure, peripheral vascular disease and recurrent urinary tract infection. The nurse professional can use the literature database to extract the information regarding the association of fall related injury with medical history of osteoarthritis or peripheral vascular disease. This data will help in the assessment, analysis and treatment planning according the published scientific research in current literature evidence.
According to the ethical aspect of nursing practice, the nurses are required to follow the NMBA Standards of nursing practice. The NMBA Standard 1.1 clearly states that the nurses are required to utilize best available evidence in clinical practice to access and analyze the patient to provide safe & quality treatment to the patient (Nursingmidwiferyboard.gov.au, 2018). The RN uses critical thinking and rational decision making abilities to link theory to actual clinical practice by employing the current scientific research published in the literature. Furthermore, the nurses are responsible for planning and communicating the plan of nursing care. Standard 5.1 of NMBA states that nurses ought to utilize the best available evidence in literature to make a safe and quality treatment plan for the best patient outcome (Nursingmidwiferyboard.gov.au, 2018).
Although there is vast data regarding the use of EBP in nursing, however; the ethico-legal aspect of EBP is equally important before its implementation in clinical practice. Cultural and religious aspects also need to be considered in actual clinical setup (Storms et al., 2015). These aspects are critical in decision making in clinical setup. Decision in nursing practice is influenced by patient choices, clinical judgment, cultural factors and religious aspects before the evidence based approach can be employed in the clinical setup. At community level, EBP can be translated as “scientific research based intervention to bring health improvement in the community. The resources that can be used by nurses to bring about clinical improvement include systemic reviews, journals based on current research and abstracts.
From an ethical and legal point of view, using EBP in clinical scenarios is as dangerous as not using it in clinical practice. To ensure the quality and safety of the treatment plan, the nurse professional should be able to evaluate the strengths and relevance of the research findings (Melnyk et al., 2014). The nurse should be able to respond to the preferences of the patient in addition to the use of EBP in the clinical setting. A responsible workforce is able to think critically and use evidence based practice in clinical scenarios to apply best practice and derive best patient outcome.
Rationale for the choice of diagnostics and how to determined which diagnostics are best suited to this presentation
Establishing a diagnosis is a challenge even for an advance practice nurse. An ailment is characterized by two things –its signs and symptoms (Storms et al., 2015). Symptoms are reported by the patient, while signs are the characteristics that the physician or health care professional observes. Once the signs and symptoms are confirmed, a final diagnosis can be made only after confirmation from diagnostic testing. When signs and symptoms of two different diseases overlap establishing a final diagnosis can be confusing. Therefore, it is important to determine the exact cause which is responsible for the appearance of the particular symptoms in human body (Storms et al., 2015). For instance, in the provided case study, a number of diagnostic tests are done before concluding the probable impression of the diagnosis. It is important to obtain data through history and physical review. In the current case study, a systemic and thorough analysis is conducted before giving the probable impression of the cause of fall. The case study is followed by the drug history and the medical history of the patient. The case study reveals important information regarding the patient. It defines the patient’s age group, her chief complaint, and the area of the injury. The past medical history is the most important aspect before establishing a final diagnosis (White, Dudley-Brown & Terhaar, 2016). The medical history helps the nurse professional in determination of the current pathologies and the course of chronic diseases in the past. While, the drug history helps in the determination of the current as well as past medications of the patient. Also, it gives a rough idea about the past ailments and chronic diseases of the patient. In the provided case study, the patient has a drug history of Aspirin intake. Aspirin can lead to uncontrolled bleeding in case of injury. Therefore, it proves that how important it is to determine the drug history of the patient. Developing a differential discovery is essential for accurate analysis. It involves a sequential analysis involving the following:
Patient history: Chief complaint
The first data received is the chief complaint or the explanation of the patient behind the search for a medical consideration. This message gives the provider the general idea of ??possible analyzes (Friesen-Storms, Bours, van der Weijden & Beurskens, 2015). For example, “fall with head strike, no Loss of Consciousness and skin tear to left lower leg.”
Subjective
The most widely recognized etiology of the fall can be either syncope, pre-syncope, stroke, hypotension or accidental. In view of this, the provider invites patients to negotiate open-ended queries to gather information identified by the problem being displayed. After a common history, the provider continues to get more points of interest through a coordinated story (Dang & Dearholt, 2017). Patients may not experience undesirable effects unless they are provoked. These queries are focused on the analytical possible results identified by the presentation problem. In this case, the patient experienced fall, and gives a history of falls in past, peripheral vascular disease, ischemic heart disease and angina. When questions about the indication have been completed, the provider continues to obtain information about the patient’s general health status and the important medical, family, and social history of the past. The pathological history of recovery and the family history of the patient determine the risk factors for disease. Social history may reveal related statements or tendencies that affect the proximity of diseases, such as heart disease, caused by smoking, or liver disease with alcohol or medication (Dang & Dearholt, 2017).
Physical Examination
Physical examination begins as soon as the patient walks into the room and the physician looks at the individual’s external presentation. Visual signs include appearance, position, anxiety, skin color, and breathing patterns. Despite the fact that they seem insignificant, the evaluation of the indispensable characters is essential and their accuracy is fundamental (Goldstein & Cates, 2015). Raised temperature, increased hear rate or low impulse is a cause of concern and warns the HCP that the patient may have an infection. Similar to the patient who came for a large-scale physical examination, the patient who has side effects requires a centralized physical examination. In the current case scenario, the patient suffered a head injury, this requires a study of the normal functioning of the heart, and respiratory system and stomach (inflamed kidney, liver or spleen). The skin is considered to look for cyanosis, club nails and edema for edema. Neurological research is limited to a mental state examination, and different parts of the study are not applicable. Physical examination may also detect unseen findings or may be quite ordinary regardless of the proximity of the infection.
Differential Diagnosis
A number of possible causes can be considered, once the chief complaint, medical history, and physical examination are completed. It will help in establishing a differential diagnosis and the most real or “do not miss” analysis. Recognizing the possible causes and exploring all potential outcomes is critical. At the same time, finalizing or making a final conclusion may lead to a demonstration error (Goldstein & Cates, 2015). The confirmation of differential determination is dictated by the extent of the health care provider’s experience. Further examination and treatment cannot be done before a final diagnosis is made by the physician. This can become a test for the physician who will have to analyze the data and compare it with probable ailments (Liang et al., 2015). With the help of diagnostic tests, the physician can strengthen the information base to further strengthen the differential diagnosis. Nonetheless, it is evident that with clinical experience, the capability of clinical judgment of a physician increases. An unskilled or less experienced physician will find it challenging to establish a clear disgnosis (Goldstein & Cates, 2015).
Diagnostic Test
When medical history and physical examination are not enough to establish a clear diagnosis, diagnostic testing is the next stage in solving the question of differential diagnosis. Diagnostic tests are expensive and thus should be done only when a clear diagnosis cannot be established based on the physical examination, medical history of the patient (Gladman, 2015). Initially the basic tests such as CBC blood should be ordered, and if the analysis remains unclear, only then more complex tests should be considered. Consider the impact and specificity of the test. “Affectability” is the range of patients with a conclusion that will test positively. “Specificity” is the range of patients without determining who will test negatively. In the provided case study the diagnostic tests conducted include Intravenous (IV) access Computed Tomography of Brain (CTB), Chest X ray (CXR), Electro-Cardio-Gram (ECG), Urinalysis and Lying and standing blood pressure (Konstantelias & Mourgela, 2018). All the diagnostic tests were important for the determination of a final diagnosis. Computed Tomography of Brain was necessary to determine any cognitive impairment as the cause of the issue. Also, CTB is compulsory after head injury to make sure that no internal injury has occurred. Chest X ray (CXR) is important to determine the normal functioning of heart as the patient has provided the history of ischemic heart disease, angina and peripheral vascular disease (Gladman, 2015). Similarly, ECG is conducted to determine any abnormality associated with sinus rhythm or arrhythmia. Moreover, the patient has provided the history of Chronic Renal Failure and recurrent UTI, thus, Urine analysis was compulsory to perform. As the diagnostic tests revealed sinus arrhythmia with no ST segment changes, heart was moderately enlarged and there was pulmonary venous distension a probable diagnosis of pre-syncope has been made based on the evidence gained from diagnostic testing.
Explanation of how to make a diagnosis by exclusion
The diagnosis by exclusion involves examining all the probable causes and then determining the diagnostic tests of all the probable organ of organ system involved. Finally, analyzing the diagnostic tests and based on knowledge of the disease specific variables, concluding the final diagnosis. In this case, the patient presented with a vast history involving abnormalities in heart, bones, kidneys and spine. Fall can be caused due to the failure of any organ. Therefore, diagnosis was made by exclusion. All the diagnostic tests were conducted involving Intravenous (IV) access Computed Tomography of Brain (CTB), Chest X ray (CXR), Electro-Cardio-Gram (ECG), Urinalysis and Lying and standing blood pressure. The results were analyzed and compared (Mockenhaupt, 2014). Abnormality was detected in functioning of heart in the form of sinus arrhythmia, heart was moderately enlarged and there was pulmonary venous distension. Her Glasgow coma scale was GCS 15/15, revealing no cognitive decline, her CTB revealed no intracranial hemorrhage and there was no evidence of acute infarction. Although her EUC- showed impaired renal function, however; it was chronic due to her medical history of Chronic Renal Failure. After excluding all the probable causes after normal diagnostic tests, we are left with abnormality in endocardia. Cardiac abnormality and sinus arrhythmia was considered to be the probable cause of pre-syncope leading to fall injury.
Several critical steps are involved in making a final diagnosis. First step towards diagnosis involves noting the chief complaint with which the patient has presented to the hospital. It will involve critically thinking about the three common ailments that have same clinical manifestations. For example, fall is most likely associated with postural hypotension, cardiac abnormality, shock and syncope. Second step involves obtaining the past medical history of the patient (Mockenhaupt, 2014). It involves noting the possible risk factors based upon the presenting symptoms of the patient. Based on the data obtained from patient’s history and physical examination the nurse must look for significant signs of illness (Hoyle, Jablonski & Newton, 2014). Cardiac abnormality and sinus arrhythmia was considered to be the probable cause of pre-syncope leading to fall injury. Thirdly, establish a differential diagnosis from the list of possible diagnoses based on the medical history and physical examination. If the data is insufficient to make a final diagnosis, further diagnostic testing should be ordered. For example, crackles in the left side of chest will require a chest x-ray to confirm the presence or absence of pneumonia. In case of elevated neutrophils or increased bilirubin a complete blood examination will help in establishing the final diagnosis (Walsh et al., 2018). Fourthly, the final diagnosis should be supported by relevant evidence that why this diagnosis is selected. The nurse needs to review all the findings before making a final diagnosis. Finally, the nurse professional should develop a treatment plan, including diagnostic testing, pharmacologic agents, patient education, and follow-up (DiCenso, Guyatt & Ciliska, 2014). If the diagnosis remains unclear, appropriate referral for further evaluation need to be considered.
