1 Critical review on qualitative research paper. Presented by:Sarah HartRoberto MassariChristian Vaughan-SpruceJaya Woodun
2 Learning OutcomesA critical review of the methodology analysing the advantages and disadvantages of semi-structure interview.Analysis of results, limitations of the study and our recommendations for further research.Clinical implications for physiotherapists and podiatrist.
3 Qualitative analysis of stroke patients’ motivation for rehabilitation. Maclean, N. Pound, P. Wolfe., C. Rudd, A. BMJ 2000;321;Qualitative researchsemi-structured interviews.explore the attitudes and beliefs in stroke patients.either high or low motivation for rehabilitation.Participants22 patients six weeks after stroke.undergoing rehabilitation; fourteen with high motivation, and eight with low motivation.Correlation found between practitioners approach and interaction with patients, and the outcome in rehabilitation.
4 Methodology Positive aspects Negative aspects Clear background and reasons given to research.Semi-structured interview gives patient control over conversation.Interviews analysed for biasGood organisation of data, themes coded.Negative aspectsCriteria to determine choice of patientsSample sizeInclusion/exclusion criteriaReliability of Semi-structure interviewInterviewer previous knowledge of patient motivation. How would this affect the interviewer?Brief overview – give some chat around as you can see we’ve highlighted some of the main points which we are now going to explore further…
5 Positive aspects Methodology Qualitative approach is appropriateClear objectives stated for researchDetails of similar previous studies given and their weaknesses notedSuitable patients chosen for study using ‘extreme case’ sampling
6 Positive aspects Interviewing techniques Semi-structured interviews allow patients control and allow them to explain things in their own terms. ‘preferable for complex and sensitive issues’Neutens and Robinson (2002)Interviews all conducted at the same time by the same interviewer.Interviews carried out over nine months until no new ‘themes’ emerged.All interviews transcribed and recorded.Interviews analysed for bias by second member of team.
7 Positive aspects Analysis of data Organisation of data - emerging themes are coded and compared across interviews.“The researcher must find a systematic way of analysing data, e.g. by drawing up a list of coded categories” (Greenhalgh,1997).Care is taken not to distort patient’s meaning and examples given about how this is done.Quotes included from patients are all traceable to individuals.‘Mixed messages’ included - “Deviant case analysis can help refine analysis until it can explain all cases under scrutiny.” Mays and Pope, (2000).
8 Negative aspects Methodology for sampling Sampling (extreme case sampling)The level of motivation of patients decided subjectively by 12 professionals.Exclusion criteriaPossible consequences of having a large group excluded.A research by Kauhanen shows that Post stroke depression (PSD) affects between 20-65% of post stroke patients. M.Kauhanen (1999)Sample sizeSmall sample.Uneven sample.Interviewer awareness of motivation of patient prior interview. Polgare & Thomas(2000)
9 Negative aspects Semi-structured interview Skills of the interviewerThe outcome dependant largely on the skill of the interviewer. Britten (1995)Time consuming /expensiveLength of time needed may be difficult to control, possibly leading to higher costs.ReliabilityThe nature of the method makes it virtually impossible to reproduce the interview in exactly the same way, therefore it can be considered unreliable.Difficult to analyseDetermining the relevance of the answers provided can be difficult. Neutens and Rubinson (2002)Skills of the interviewerThe outcome dependant largely on the skill of the interviewer and his/her ability to direct the interview and gauge the information wanted while maintaining a professional attitude.
10 Analysis of Table Characteristics of sample of stroke patients High motivation (n=14)Low motivation (n=8)Male 10 3 Median (range) age (years) 72 (38-86) 78 (54-85) White 5 Black Caribbean 2 Black African 0 1 Asian Median (range) Barthelscore* at interview 14/20 (4-19) 7/20 (3-10) Table is not explicit and clear – we believe that the table is not complete and is lacking relevant information.Table does not show any female statistics such as: age, ethnicity, median range, Barthel score - (explain table).*Barthel score: 0-14=moderate/severe disability; 15-19=mild disability; 20=independent.
11 Analysis of results Information being conveyed twice. An overall lack of communication between patient and members of staff .Misconception of the term ‘Motivation’ and everything is based on clinical judgment.No follow-up.
12 Review of resultsResults must be independently and objectively verifiable. Greenhalgh (1997).According to Greenhalgh (1997), exposure to a lack of validity raises questions over accuracy and findings.Physiotherapy (CSP 2005) and Podiatry (SOCAP 2005) communicate effectively with other health professionals and relevant outside agencies to provide an effective and efficient service to the patient.More research should be undertaken: to define motivation and enhance clinical judgment and eventually get a better outcome.too much text on screen?
13 Advantages of the study Investigating an under researched topic.The authors felt that a broad range of viewpoints had been covered due to age, sex and ethnicity in the sample.Whilst reviewing the paper we felt that there wasn’t a fair representation of all demographics as only 22 patients were interviewed.Figures on the stroke.org website report (which commissioned the report) 110, ,000 people each year are diagnosed each year with a stroke.
14 Limitations of the study Small sample.Ignore clients with depression.How to judge a patient motivated orunmotivated.
15 Clinical implications Clinicians should direct patients to websites that are either government run or charity based.The entire MDT must work on their communication not only with each other but the patient as well.The clinician must involve the patient in goal setting. This counteracts the sense of helplessness that may give rise to depression (French 2005)The authors recommendations are availability of literature to patient and families.Asks that nursing staff do not send “mixed messages” to patients regarding rehabilitation.The clinician must be aware not to place all the responsibility solely on the client during rehabilitation
16 Further ResearchSeveral studies after this one cited this paper in their research the authors themselves two years after this study investigated the role of the clinician in motivation.From this our recommendations are:-To use a bigger sample size.Include patients with depression.Follow-up after initial interview.Need to define what “high” and “low” motivation is.
17 Conclusions Client and practitioner relationship. Improve communication with the patient and within the MDT.Goal setting - should be as functional as possible.
