Argue The Relative Value Of Qualitative Or Quantitative Reseaech To Underpin Professional Practice

vicenary inquiry1 . IntroductionIn any wellness cargon practice , the cautiously planned and implemented explore is of broad rank . The explore moldiness adhere to the superiorest standards of scientific practice . There is no such activity as a perfect interrogation count . as yet , tout ensemble well somaed look intoes leave al sensation contribute to existing certify even though they whitethorn non provide or so reliable results . In wellness c atomic number 18 query , a combination of the sciences of epidemiology and clinical studies has contributed to erupt association around the powerfulness of health practices . Many question methods were first established in epidemiology . However , today they argon applied widely in health tending in to quantify the utileness of new treatments , interventions and health cargon practices with frugality This provides analyses of the of the essence(p) features of duodecimal investigate methods (based on counting and standard ) that require c argonful consideration at any turn ons and be of great esteem in health c ar practice2 . Advant durations and Disadvantages of numerical seekHealthcargon professions atomic number 18 characterized by a body of specialized hit the hayledge . Commonly this k nowadaysledge is the results of quantitative interrogation . As for skipper fields such as healthc be , quantitative explore is diminutive for development . There are two direct advantages number angiotensin converting enzyme , quantitative search yields new issueledge cogitate to the several(prenominal)(prenominal) issues , questions , and problems in healthcare . Second , quantitative look ensures a put to work for distributing such knowledge when and if it is considered to be of high gear quality . denary explore , thus , has both a product and a transition aspect . It addresses substantive findings and the litigate of starting and reporting them . Quantitative look into is the essential force of practice of medicine , aiming to advance transforming of masters and improve practice (Creswell 1994 ,.69There are principal(prenominal) prejudices related to quantitative search in healthcare . counterbalance , quantitative research is built on the assumption that worldly concern exists largely independent of the researcher . Quantitative research is accustomed to materialisation . It fixes in time touch ones that might be genuinely situational , dependent on circumstance , and fluid . Events that depend on the social interaction among organizational members are nasty to subdue with quantitative research which assume stability Since many aspects , such as motivation , satisfaction , and commitment cannot be today perceived and measured but essential(prenominal) be deduced , at that place is a problem of misinterpretation and understanding what the observer wants or expects to understand rather than what is really thereA second major disadvantage of quantitative research is connected with the application of knowledge obtained (Creswell 1994 ,.72 . The serious goal of researchers of quantitative research is to interpret reality and , maybe , comprehend how events are related to each other(a) . It is not the fundamental objective of researchers to solve problems or substantiate conclusion what action to take . The goals and tasks of researchers and professionals , thus , differ . interrogationers attempt to deal sense of what has already befalled , professionals try to influence what is about to happen . Much of research , therefore , does not transform immediately into practice . Healthcare requires attention to many much situational events than a quantitative research chew over can usually greenback for3 . Improving health care deli veryQuantitative research is needful to understand the operations of medicine today . bringually , there is no other way to evaluate and understand the healthcare issues , videlicet (Anderson 1996Placing long-sufferings needs ahead of self-interest scholarship reaction to social needs working in quislingism with other health professionalsAdherence to moral principles , respect , sympathy , responsibility politeness , sensitivity to patient needs and to members of a staffHigh standards of moral and honorable behaviorIdentification and care of physician impairment in peers and selfPsychosocial aspects for careUnderstanding of the importance of self-assessment , and desire to teachUnderstanding of the requirements for club of patients in research studyKnowledge about the differences in gender , age , cultural , and social backgroundFairness and reliabilityTwo necessary components in the process of delivering high quality health care are the presence of scientifically based research and the practice of good critical judgment skills in to select the most fascinate essay . vital judgment skills are necessary for helping to see whether quantitative research is of a sufficiently high quality to place that salmagundis in health practice are necessary . In this process , the disciplines of critical idea and research methods both attendant and cover one another . Critical appraisal is a process that helps to determine and foster quantitative research4 . Scientific meritCritical appraisal is the tool use to evaluate the scientific merit of a research (Brannen 1992 ,. 145 . Critical appraisal has become an grave clinical tool . The fundamental function of clinical appraisal is to inquire about whether a reported connection amidst an intervention and a health results has causal relation or can be explained by other factors such as occasion , bias or confusion . This approach is necessary in healthcare because professionals can only contract evidence in topics that could not have arisen by chanceCritical appraisal skills are essential for professionals . They use it in to make finiss about whether to miscellanea clinical practice on the basis of the published literary works . Critical appraisal skills are too employ for devising decisions about the most important directions for future research . In judging the published belles-lettres as valuable evidence , the conclusions reported must be justified regarding the appropriateness of the study methods used and the validity of the outcomes kick ined . This can be achieved with a vowelize understanding of the limitations and the benefits of different research methods (Sellitz Jahoda , Deutsch , and Cook 1976 ,.2155 . Systematic reviewsNarrative reviews and articles , which look constantly in most journals , lots use the teaching that supports the authors points of view . These articles are necessary in to be authorized of new concepts and ideas . However , it is important that health professionals conduct positive reviews that consider and summarise all of the relevant studies that are availableSystematic reviews must use highly developed methods for finding and critically assessing all of the relevant literature and for making a summary of the findings . The process of dogmatic review consists of the following steps (Atkinson and Coffey 1997State precisely outcome variablesDetermine intervention or exposure of interestDetermine search strategy and literature databasesDetermine inclusion and exclusion criteria for studies have searchExamination of studies by two independent observersReach organisation about inclusion of studiesConduct reviewPool data and accomplish meta-analysisPropose and produce net review6 . Cochrane collaborationThe Cochrane collaboration has become an international system of great value . It monitors and publishes systematic reviews . Cochrane stated that a systematic review of a series of randomised controlled trials was a real milestone in the annals of randomised controlled trials and in the evaluation of care (Biltereyst 2001 ,. 52 . Since because , this has become the essential method of evaluating evidence for health care Cochrane withal stated that to have continuing value , reviews must be all the time updated with any new evidence and must be easily available through various(a) media (Biltereyst 2001 ,. 537 . Undertaking a Cochrane reviewThe fundamental task of Cochrane collaboration is to instigate the interest and eagerness of clinicians and researchers to be aware of new reading . The aim of the programme is to provide professionals with the motivation , skills and supervision that are needed to conduct research to the standard required . The Cochrane collaboration assists its reviewers by presenting documents , coordinating seminars and providing software for summarising the results . The main principles of the collaboration are the following (Punch 1998 ,.69consider specific health problemstrain professionals in the review processprovide a collaboration of people with common interestsprevent duplication of literature reviewsteach returnive search strategiesconduct meta-analysesMeta- uninflected findings are of the great value in healthcare . What is epidemiologically important is necessarily clinically important . The findings usually change clinical decisions . Meta-analysis is practiced as a method of evaluating whether a stir upicular treatment works and more than that . Meta-analysis is developed and used far beyond clinical trials . Observational descriptive and analytic studies and the evaluation of diagnostic methods are also of great value . Meta-analysis in these fields works well . The pooling of results is sometimes appropriate (Neuman 1994 ,.258 . Evidence-based practiceEvidence-based practice is an approach of quantitative research . It uses the best scientific evidence available with purpose to deliver the best patient care . The approach of evidence-based practice is means that it is better to know for sure , rather than believe . Assessments of probable effectiveness are best achieved by using systematic methods to assess the available literature in to provide true answers to particular questions about healthcare . This process is connected with the recognition that change magnitude amount of research studies are being published that have disenable findings for clinical care practices . The basic steps of evidence-based practice are the following (Bailey 1994Determine the problemBreak the problem d experience into questionsFind relevant clinical articles . Conduct an effective literature searchDefine the best studiesEvaluate the evidence considering validity , repeatability , relevance study strengths and weaknesses , outcomes etcMake clinical decisions , examine policy and implement the findingsAssess the outcomes of changes in practice9 . Benefits of evidence-based practiceThe evidence-based practice has many benefitsfocuses new research on virtual(a) issues of great valuecan be practiced to evaluate existing surgical process or give approval to the implementation of new practiceshas the capacitance to occupy to more effective decision making and more effective health care auction pitchsaves time when regular reviews are available or when evaluations of research are publishedThe practice of scientific reviews of the evidence in to assess the effectiveness of clinical practices increases the adventure that the healthcare delivery will be more effective . This process is improved by easy access to systematic reviews , for instance through the Cochrane collaboration , and by the making knowledge public through journals such as Evidence-Based Medicine (Reason and Bradbury 2001 ,. 27810 . innovation a researchIn conceptioning a study and assessing the outcomes of studies conducted by other research groups , it is essential to determine the strengths and the limitations of the different types of research fancy that can be used (Creswell 1994 ,.36 . The choice of a research design is an important decision in designing a research by healthcare professional The research design makes clearer with which a hypothesis the research can be time-tested , or to which causation it can be impliedUsually , the research design that is chosen must be fitting for answering the research question . It also must be proper for the surround in which it is used . The different study types for the research are the following (Barbour and Kitzinger 1999Systematic reviewCohort studiesFollow-up studiesNon-randomised clinical trialsPragmatic trials look-control studiesMatched case-control studiesCross-sectional studiesPopulation studiesEcological studiesCase reports11 . Choice of outcome criterionsProfessionals must cover mach attention when choosing the result and explanatory variables that will be used to test the main hypotheses in a research study . It is essential to use both outcome and explanatory measurements that are as undefiled and as valid as thinkable . This will increase the likelihood of being able to powerful determine the impact of interventions . The main features of accurate outcome measurements are the following (Black 1999good face and content validitygood criterion or rebuild validityrepeatablegood between-observer agreementresponsive to change wide face and content validity are both essential characteristics of outcome measurements . They ensure that the measurement determines the symptoms and illnesses that are important in clinical terms . Besides measurements with good criterion are of considerable importance because they measure what they are expected to measure with as much precision as possible . It is also important that measurements have good between-observer agreement and are accurate , or repeatable (Bernard 1995 ,. 6912 . Calculating the Sample SizeSample size is one of the most important issues to consider when designing a research study . The size of the sample has effect on all aspects of conducting the research and interpreting the outcomes . A research study must be large plenteous to guarantee the faithful measurement of the results . Simultaneously , it must be miserable enough so that the research question can be answered aloneThe following issues must be considered when calculating sample size (Babbie 1990Clinical importance - effect sizeVariability - spread of the measurementsResource availability - efficiencySubject availability - feasibility of recruitmentStatistical power - correctnessEthics - match sample size against burden to subjects13 . Study managementThe data assemblage stages must be correctly planned and conducted . The scientific oneness of the study must be maintained throughout the process . It is unethical to conduct a research that is poor . It is also unethical to present poor quality data that understandably will lead to poor quality results14 . information CollectionQuantitative research may give rise to particular difficulties about the ethical responsibilities of researchers in relation to dealing with the data collected . Researchers very much use questionnaires from large numbers of patients . One instance is a research that set out to document the frequency of gastrointestinal symptoms in the alliance (Hammersley 1996 ,.159 . Because of the large sample required to obtain the necessary accuracy in the study , a small proportion of subjects turned out to have a daedal of symptoms suggesting the possibility of serious but until this time unrecognized , gastrointestinal disease (Jones and Tait 1995 , pp 67-70 . These symptoms were reported : rectal discharge changes in intestine habit , persistent abdominal pain , weight way out and difficulty in swallowing . The symptoms were reported by patients responding to structured questionnaires designed to determine the frequency of such symptoms . The individuals had been selected at random from registers held by health authorities and the practitioners had carefully examined the lists of participating patients before tangency by postThe practitioners that were involved in this research study uttered an interesting range of views . Some expressed a win over belief that schooling of this kind should be reported without determine so that appropriate action , perhaps an invitation for the registered patient to meditate their everyday practitioner , might be taken (Crosland and Jones 1995 ,. 486 . This , clearly , could be considered as a breaking of obligation of the confidentiality and anonymity promised by the researchers , even when such reporting is possibly to have been in the medical interests of the patient concerned . Autonomy is in conflict with kindness . Some professionals , however , took a completely opposite ethical function , and claimed that patients have a pay off to decide themselves about whether or not to consult . Although this position can to some degree be countered by argument that many patients absolutely do not have enough needed culture on which to base an informed decision about seeking medical advice , its proposers claimed that patient autonomy and confidentiality of randomness should have taken priority over uninvited medical intervention (Hammersley 1995 ,.245 . It is important that these issues are considered and resolved to the satisfaction of the research team , the participating practitioners and the subjects of the research study before the research begins15 . Sequence for data analysisAnalysing the data and interpreting the outcomes is one of the most exciting stages in a quantitative research study (Bryman and Cramer 1997 ,.93 . The analysis provides the answers to the study questions However , this stage is one of the critical stages in the search for truth .

Therefore , it is important that the process is undertaken in a scrupulous and considered way . In general , the data analyses should go through the logical steps . First it should be conducting univariate analyses and then the bivariate and the multivariate analyses (Alvesson and Sktzldberg 2000 , pp 96-816 . Research ResultsResearchers must protect the sources of research information . Protection is important part of the undertaking of confidentiality and anonymity It may , however , be that passage to excessive amount to keep secret the sources of data makes it unrealistic for readers of the research report completely to realise the setting in which the research was conducted and to decide whether the results can be applied to their own setting It is also important for the subject of the research to be able to see the research results before they are publishedProviding results to subjects is very important in clinical settings For example , in one study on general practitioner referrals of patients with rectal bleeding , 83 per cent of patients said that they would appreciate a double of the study (Greenwood and Levin 1998 , pp 36-42 . In another study on patients consulting behavior , almost two-thirds of participants asked for information about the results (Greenwood and Levin 1998 ,. 56 . This may refer willingness for more involvement and wish for more information by subjects in some areas of research at least . However , there are logistic difficulties when professionals provide this information . It is difficult for professional to interpret the information when it forms part of a professional report . It is clear that an abbreviated or summary transformation of the research can be made separatelyThe unpleasant results of airing of research information for the subjects also need to be considered . Research information sometimes might simply stigmatize certain social groups and create inappropriate stereotypes . Changing research information because of the interests of the lay media may produce a caricature of not only the research results but also the research subjects (Alasuutari 1999 ,. 69 . Research that has suggestions for increasing the provision of medical services , with resource allocation implications , may create inappropriate expectations in the estimates of the subjects and leave subsequent disappointments (Denzin 1989 ,.39 . Researchers also need to have in mind that future research collaboration is likely to be of great value . Therefore professionals should remember that the presentation and discussion of information in which judgments of the subjects of research are either explicit or implicit may jeopardize thisConclusively , it is important to think carefully about the possibility of over-researching particular groups or individuals . It will be useful for professionals to keep careful records of patients who have been involved to act in studies , and for practices to do the same This presents a further intellectual why general practitioners should of all time see lists of patients selected from catalogues before they are used for research studies17 . Nurses are given resuscitation power . Case StudyAccording to new guidelines to health professionals , nurses are able to decide that a dying patient should not be resuscitated . Until now , only GPs and consultants had authority to decide whether there was any point in making efforts to save a life . In 2007 guidance by the British Medical Association has changed . promptly suitably experienced nurses have power to make this important decision (The Daily Mail 2007 ,. 1 . These new guidelines generated many controversiesThe research questions were as follows : 1 ) some experts feel that prolong resuscitation efforts can be undignified and often worthless 2 ) the survival rate after a patient has a cardiac arrest and receives cardiopulmonary resuscitation is relatively low 3 ) nurses only are able to make such decisions - they know more about the personality of the patient 4 ) often it is a long and traumatic procedure and is not always successful . The guidelines met oppositions , such as : 1 ) these senior nurses should be properly qualified and in a position to make these decisions 2 ) a person can die because of unconditional decisionThe relationship between theory and practice should receive some attention within the nursing literature . The qualitative data from debriefing interviews with nurses should be gathered . The nursing power to decide whether patients should or should not be resuscitated is being subjected to increasing research18 . ConclusionThe future certainly belongs to the quantitative research Well-entrenched quantitative research is complementary to health problem solving . Quantitative research reflects the current state of medicine today . Ultimately , physicians should witness more and more about qualitative research . Good quantitative research and its results do not necessarily lead to good clinical decisions . They are , however , the necessary grounding of good decisions . These decisions put research results within a context where the patient , the care professional and the conditions and circumstances of health delivery are brought to get goingher for optimal successQuantitative research in health care generates a set of ethical questions , and some dilemmas . In particular , health care researchers have to be rather aware about their responsibilities to the patients Little information is at present available about patients views of being involved in research of this kind . This would be an important base point for evaluating methodsBibliographyAlasuutari ,(ed ) 1999 .
