Reliability and validity are ways to demonstrate the trustworthiness in current research (Roberts et el, 2006). If healthcare professionals change their clinical practice based off research, then the results from the data should be honest and free from errors. Think about the implications, in my institution, we are ready to change the way we use Exparel in post–op pain management based of the data that I help collect with a resident over a two year period. We spent countless of hours not only collecting the data but analyzing with the help of a biostatistician and pharmacy to ensure that are numbers were correct. Our team knew that our results must be honest and trustworthy because patients care would be effected by our research.
Validity

In qualitative research validation is expressed (or measured) by how well the research tools measure the particular phenomena being studied (Roberts et el, 2006). There are two broad measures of validity which includes external and internal measure (Roberts et el, 2006). Internal validity addresses the reasons for the outcomes of the study through assessing one of three approaches: content, criteria, and constructive validity. Content is considered the weakest form of validation (individual questionnaires) however, it can be more effective if you uses pilot studies and/or "backed up" with literature reviews or other documentary evidence (Roberts, et el, 2006). Criterion validation is a much stronger use of validation which consists of using a questionnaire in comparison to similar forms of measurements. However, similar forms of measurements must already exist for this to be possible (Roberts et el, 2006). Construct validation is the degree in which a test measures what is being claimed, tested or theorized (Roberts et el, 2006). External validity can be described in ways of generalizations compared to similar situations or people, such a larger population
Melnyk’s Hierarchy of Evidence is a system often use for assigning levels of evidence in nursing by integrates clinical expertise and patient choices with the best available research. It is represented by a pyramid that enumerates the levels of strength of the evidence from 1 to 7, of which level 1 is the higher level. The higher level on the pyramid, the more likelihood that the research is valid; therefore, answering a clinical or practice question. “The systematic review or meta-analysis of randomized controlled trials are at the top of the evidence pyramid and are typically assigned the highest level of evidence, due to the fact that the study design reduces the probability of bias” (Melnyk, 2011). The weakness of the system is that when
Green (2005) identifies that, “Using evidence from reliable research, to inform healthcare decisions, has the potential to ensure best practice
1.4 face validity is the evaluation which the items in a scale adequately measure the construct. Face validity can be judged after the measure has been developed by potential measurement
152). EBP has inspired nurses to acknowledge the significance of theory and research and utilize it to their area of practice. Through strong educational foundation and advanced practice, APN is able to comprehend the relationship between research, theory and EBP and utilize it in providing quality care to patients. Best research evidence is indispensable, as nurses nowadays use pragmatic evidence in practice and not just previous experiences or beliefs (Chinn, & Kramer, 2011). Evidence based practice has been proven to upgrade patient outcomes, reduce health care expenses, and cause increased patient and provider satisfaction. By using evidence-based care and theories, patients are given proper assessment and treatment without wasting valuable money and supplies on testing and procedures that are not
The Royal College of Nursing in the United Kingdom developed the “Promoting Action on Research Implementation in Health Services (PARIHS) which is a multifaceted framework. According to the PARIHS, the formula for successful implementation of EBP incorporates three components: clinical expertise or expert opinion, outside scientific evidence, and patient perspectives to provide high-quality services that reflect the values, interests and needs of the individuals served (Rycroft-Malone, J., 2004).
Polit and Beck (2010 p. 4) describe the research process as “a systematic inquiry designed to develop trustworthy evidence about issues of importance to the nursing profession, including nursing, practice, education, administration and informatics”. With the use of research, nurses can update themselves with the knowledge and analytical skills necessary to facilitate the use of appropriate evidence in clinical decision making for effective health service delivery (Greenhalgn 2010). Clinical decisions should be supported by current, appropriate and robust evidence rather than invalid primary training or the interpretation of personal experiences (Thompson and Dowding 2002). Baker (2010 p. 6) defines EBP as “the conscientious, explicit and judicious use of theory-derived, research-based information to make decisions about care delivery to individuals or groups of patient, taking into consideration individual’s needs and preferences”. It offers the nurse with the skills and knowledge to assess best update health care literature and practice (Donald and Greenhalgh
The next stage is for the team to jointly develop an evidence-based practice standard based on the information compiled during the research process (Doody & Doody, 2011). An important concept of evidence-based practice as pointed out by Doody & Doody (2011) is the involvement of the patient in the development of new standards. The developed standard should apply to the research topic that is being addressed, however; it should also be modified from person to person based on morals and values for the standard to truly be evidence-based (Doody & Doody,
Evidence based practice (EBP) is "the conscientious, explicit and judicious use of current best evidence in making decisions about the care of individual patients. The practice of evidence-based medicine means integrating individual clinical expertise with the best available external clinical evidence from systematic research" (Sackett et al, 1996). This definition takes into consideration the need to delve into the professional’s clinical knowledge (Burns, 2007) as well as looking into the best evidence to support the professional. Clinical practices may become out dated if new evidence is not sourced and professionals should be aware of appropriate evidence that can be integrated into their practice (Aveyard & Sharp, 2013). EBP is important
“At its core evidence based ‘anything’ is concerned with using valid and relevant information in decision making” “high quality research is the most important source of valid information”. Psychological Association (2006, p. 273) defines EBP as "the integration of the best available research with clinical expertise in the context of patient characteristics, culture and preferences. " When caring for patients it is fundamentally important to have a good selection of up to date evidence Based Practice clinical articles to support research strategies, this allows professionals to assemble the most recent and accurate information known which enables them to make decisions tailored to the individual’s plan of care. It is essential to have clinical expertise and have the involvement of the individual patient, they must have full engagement and incorporation in order to have the accurate evaluation.... ... middle of paper ...
The idea behind conforming to evidenced based practices is that research is the most likely tool to improve patient
Thus, it is imperative that evidence-based practice is conducted to provide the best current, valid and reliable evidence in an aim to close the gap between non-conformity and coincide with the professional obligation of providing the patient with the best possible care (Liamputtong, 2013).... ... middle of paper ... ...

In health care, evidence-based research is crucial. Nurses revolve their practice on evidence so that they may provide the best health care. Without research, there would be no evidence to prove health care related findings (Shmidt & Brown, 2012). With appropriate
Evidence-based medicine (EBM) has been described as “the conscientious, explicit, and judicious use of current best evidence in making decision about the care of individual patients” . Evidence-Based Practice is a thoughtful integration of the best available evidence, coupled with clinical expertise. It enables one to address healthcare questions with an evaluative and qualitative approach. It is about applying the best available research evidence in provision of health, behavior and education services to enhance outcomes. Evidence-Based practice is about performing the best possible practice in order to provide the best possible care .
The word validity mainly refers to the data collection and whether it is true. I am a skeptic. If a questionnaire, which was aimed at young girls, was carried. out the validity would look at the results and think how truthful they were. The questionnaire might not have been answered by who it was.
