Features of Communication in Persons with Dementia
o Dementia associated with problems in comprehension, word finding, short term memory (Blair et al, 2007)
o Verbose and circuitous speech in AD (Appell et al, 1982) o Reduced lexical diversity in AD (Fraser et al, 2015) o Long pauses before response (Elsey et al, 2015) (Jones et al, 2016) o Difficulty with responding to compound questions (Elsey et al, 2015) o Turn taking largely preserved, but slower to respond and shorter turns
(Hamilton 1994) (Ripich et al, 1991)
Features of Communication in Patients with Dementia (cont…) o More likely to assent (Sugarman et al, 2007) o Use humour, accounts and face-saving (Saunders, 1998)(Lindholm, 2008) o Reduced participation in consultation, possible causes include:
• Carer or HCP assumptions about incapacity (Karnieli-Miller et al, 2012) • Direct or indirect requests to companion for help (Elsey et al, 2015), including
head turn (Larner, 2012) • Protective caregiving (Hasselkus, 1994) • Pauses or inability to answer (Jones et al, 2016) • Difficulty in securing and holding onto the “conversational floor” (Perkins et al,
1998) o May not recall diagnosis (NB: companions may not either)(Zaleta et al, 2012)
Conversation Analysis – how doctors “design” the diagnosis delivery has implications for the patient’s understanding
3 topics for consideration and discussion: • Test result feedback • Words used (design) of diagnosis delivery • Discussing prognosis
Push to increase diagnosis rates • Timely diagnosis – aid decision making
How do doctors tell people they have dementia?
Cognitive Tests • Average time spent 00:47 (00:05-05:10)
Brain Scan • Average time spent 01:29 (00:05-13:05)
Test Feedback includes indication of the consequences: • Prepares patient for the diagnosis (Maynard, 2003)
• Can help gauge diagnosis reaction
Feeding back test results
Forecasting Indicating the diagnosis as a consequence
Patient Resistance Attributing to age
DR: (name) did the tests again this time .hhh (0.8) it does seem that things have got quite a bit worse with the memory PT: w worse DR: yes yeah I mean you did okay on some of the test but .hh I think a lot of the test you- you- (.) you struggled quite a bit with .h hh so there was quite a big change from (.) from the time before PT: yeah ah (inaudible) you know (0.8) the old age can come [in as well] you know DR: [mm ] DR: yeah I mean I think- I think what we’d say is is that is that (.) i- it is (.) the problems are more than we would expect for someone [of your age] PT: [mm er ]
Repeat evidence from testing Work against resistance
Feeding back test results – e.g. 1
No indication of consequence
Patient misunderstanding
Misalignment
Feeding back test results – e.g. 2 DR: well I can give you a score out of a hundred PT: right (0.4) DR: so if naught was the worst you can do and a hundred was the best [you got] seventy eight PT: [mhm ] (1.1) PT: well that’s not bad [is it ah heh] DR: [we- we’d ] well (0.6) I I kind of think it probably is significant for yourself (0.5) DR: cause although for some people I might think seventy eight’s not- not so bad score (0.8) you you’re smarter than the average person. (.) PT: oo hooray (.) CR: huh huh hah hah hah
Clarify evidence Work against misunderstanding
Use of medical jargon
Feeding back test results PT: I was an accountant actually DR: well- well- well e[xact]ly a[nd a]nd- (0.3) that that’s PT: [mm ] [mm ] DR: the bit (0.3) that (0.3) that got (0.4) got me thinking (0.3) DR: I’ll tell you why because (0.5) the- where you lost points and you lost points on the um (.) memory tests (0.5) a bit on the visuospatial .h but also on on the maths test (.) PT: [(?)] DR: [and] that’s why I thought that was (.) that was probably significant (.) for you [if you know what I mean] PT: [oh right ] yeah ha ha haha oh did I
Positive consequences of test results
DR: the scan didn’t really show any significant change in the brain (0.3) PT: oh right DR: so it- it didn’t show that there was any significant um change in the blood vessels there’s no evidence (.) that you’ve had any strokes at all or anything like that there’s no vascular change (.) PT: right DR: so I think (0.6) uhm what we have to do today is to (.) put together (0.6) three things we have to put together the history of the memory problems [as you] described so PT: [mhm ] DR: well the scan result (0.3) and the results of the (.) memory testing that we’ve done (.) PT: right
Feeding back test results – e.g. 3
Confusing link to diagnosis
Feeding back test results – e.g. 3
DR: and we have to (0.3) think of what most what might be the most likely diagnosis or the most like[ly ] PT: [right] (0.3) DR: explanation for why you’re having these memory problems PT: r[ight] DR: [over] over the last four or five years PT: right DR: and given that your scan hasn’t shown any changes in the blood vessels or an[ything li]ke that (.) .hh I think PT: [right ] DR: the most likely diagnosis is that you’ve- got an early Alzheimer’s dementia
Design of a Dementia Diagnosis
All doctors name dementia to the patient (contrary to previous literature) Majority of doctors deliver diagnosis to the patient (rather than the companion) Common and differing features across the diagnosis deliveries
Re-reference evidence and symptoms Working against resistance
Downplaying severity Softening the blow
Introducing dementia as a medical label Against resistance? Enhancing understanding?
Delivered through
inference Against
resistance, more
sensitive
Delivered directly Blunter,
enhances understanding
Example 1
1 DR: it’s hh (.) they- we we call this combination of (.) you
2 know m memory difficulty and blood vessel change in the
3 brain
4 PT: mm
5 DR: we call that vascular dementia.
6 (.)
Design of a Dementia Diagnosis
Example 2 1 DR: erm (.) so the name that we give to these sorts of memory
2 problems that develop (.) when we (.) er in in older age
3 (0.3) are- (0.4) is that I think that you have a m- a mild
4 form of a condition called dementia
5 (.)
Potential resistance: • Re-referencing evidence and symptoms • Inferential delivery
Potential trauma: • Inferential delivery • Downplay symptoms
Potential misunderstandings: • Re-referencing evidence and symptoms • Direct delivery
Design of a Dementia Diagnosis
• Prognosis not mentioned in 11 (13%) of the meetings • Only discussed in context of medication in 20 (25%)
Prognosis
Non-specific language No explicit discussion of prognosis
Prognosis in Medication Description
DR: I mean in terms of other (0.3) the other thing that we can do is to give you a tablet if you would like PT: mm DR: um (.) a memory table[t ] PT: [ye]ah DR: um which (.) um (1.4) what we find is on average people tend to what it does is it stabilises things for about twelve to eighteen months PT: mhm
• Addressed explicitly in 50 meetings (62%) • 16 asked by patient or family
Prognosis
Explicit discussion of prognosis
Qualifying language
Emphasising slow progression
Downplaying
DR: the nature of the condition itself is that it does tend (0.4) tend to get worse over time (0.8)
DR: but (0.4) that time period isn’t (.) a matter of weeks or months it’s over many years (.) normally that we see (.) changes (.) DR: um (0.4) so (1.2) it’s not so- (.) what I’m not suggesting is that you’re going to see things getting worse very quickly CR: mm DR: but it (.) still it’s quite useful for you and your family to know that it it may be that over time (0.8) things (0.4) you know things might change a little bit
Prognosis
Choice and placement of words affects interpretation:
• Test result feedback • Adding meaning to show patient the consequences
• Diagnosis delivery • Work against resistance and trauma, encourage
understanding • Discussing prognosis
• Explicit vs Medication discussions, downplaying severity, emphasising slow progression
Summary – Communicating a Dementia Diagnosis
SENSITIVITY HONESTY
How can doctors balance sensitivity in delivery with honesty about prognosis, so people can benefit from
timely diagnoses?

How do doctors recommend medication in memory clinics? CA work in other medical settings show 5 treatment recommendation formats • Assertion • Offer • Suggestion • Proposal • Pronouncement
In different settings recommendations are made differently
Treatment Recommendation Frequency
Suggestion 43% (n=31)
Proposal 25% (n=18)
Assertion 13% (n=9)
Pronouncement 12% (n=8)
Offer 10% (n=7)
• In primary care: 64% pronouncements, 22% suggestions
Frequencies of recommendation types
Assertion followed by suggestion Assertions prior to recommendation in 60% (n=44) cases
Typical treatment recommendation format
Assertion: statement of fact without indication of benefit to patient
Caveat: e.g. not a cure, can have side effects
Suggestion: up to patient to decide, with endorsement from doctor
DR: there are some tablets for (.) for memory problems (0.6) CR: [yeah] DR: [ u]m (.) DR: there (0.3) unfortunately are (.) they’re not a cure but they can (.) [help (.) sort of slow] things down CR: [ (?) ] CR: yeah (0.5) DR: um (0.3) uh I did I mean I (0.4) the- (0.3) that was one thing I wanted (.) to (.) to talk to you a- (0.5) today about is the (.) is the tablet um (0.6) and see whether you would be interested in in in (0.4 trying some tablets for the memory (0.5) PT: mhm (0.4) mm yeah
Typical treatment recommendation format
Assertion Assertion
Uptake from patient
DR: but also there is now medication that we can offer peo[ple] PT: [yes] that’s the- w- I’d like to have that if DR: yeah
Offer: doctor declines to endorse but offers willingness to prescribe
DR: so I mean you can try those tablets if you want to (.) DR: it depe- depends how you feel about it really (0.3) (no PT uptake)
Offer
Proposal: patient invited to endorse doctor’s idea
DR: I think that there is a tablet that (.) could help (0.7) you to (.) to for your memory to be even bett[er] PT: [oh] good good (.) DR: shall we give it a tr[y ] PT: [ye]ah
Proposal
Pronouncement: assertion of what treatment will be without patient choice
DR: so I would want to prescribe a medication for you (.) PT: mhm
Pronouncement
“well” – dispreferred response
Common reason for not taking medication
DR: would you like to think about taking some medication (0.6) PT: yes well (0.9) see how it goes I’ve got a lot of medication I take almost every day
Patient resistance
Treatment Recommendation Frequency
Suggestion 43% (n=31)
Proposal 25% (n=18)
Assertion 13% (n=9)
Pronouncement 12% (n=8)
Offer 10% (n=7)
• 22% patients resist medication – only after suggestions or proposals
• 39% suggestions and 22% of proposals are resisted
Frequencies of common recommendation types
Different Approaches Presenting medication
Emphasising positive effects of medication
Downplaying side effects
Downplaying effectiveness of medication
Example 1 DR: it will slow it down in terms of it getting worse PT: mm DR: um (.) so if you like it stabilises things to a [degree] PT: [yes ] yes DR: um (0.4) .tch there a:re some side effects with it (.) DR: they’re they’re fairly mild and most people (0.6) tolerate it okay
Example 2 DR: so there is evidence that (0.4) about (.) er forty to sixty per cent of people who take the medication probably show some signs of benefit (0.6) DR: so it’s not a magic bullet PT: mm DR: by any means
Tips for Communication:
• Eye contact, other cues to recruit attention of person with dementia • Adjust level of information to degree of cognitive impairment • Linking reported symptoms with diagnosis • Check understanding • Avoid compound questions • Allow time to respond to questions
