20 A survey exploring patients’ and healthcare professionals’ attitudes towards placebo treatments

Objectives

Evaluate patients’ and healthcare professionals’ attitudes towards deceptive and open-label placebo treatments, its perceived effectiveness and current use.

Methods

A sixteen-item anonymous survey explored attitudes towards deceptive and open-label placebo treatments in clinical practice, its perceived effectiveness and current use. The following groups completed the survey: 288 people with a neurological condition, 138 people with a functional neurological disorder, 61 people with a medical condition, 59 healthy controls and 112 healthcare professionals, of which 45 neurologists and 20 psychiatrists/psychologists.

Results

The overall attitude to deceptive placebo treatments was favourable amongst non-professionals (69% in favour). The healthcare professionals were more conservative, with only 48% being in favour. However, a considerable number strongly opposed deceptive placebo: 15% of medical patients, 11% of neurological patients and 22% of patients with a functional neurological disorder. Forty-one percent of functional neurological disorder patients, 46% of patients with presumed organic conditions and 70% of healthy controls believed that a deceptive placebo would improve their own symptoms. Healthcare professionals estimated that deceptive placebo treatments would be effective in 31% of purely organic symptoms and in 55% of purely functional symptoms. Major concerns surrounding deceptive placebo involved undermining trust in the medical profession. There was marked scepticism with regards to open-label placebo in all groups, with the general underlying belief that open-label placebo is fairly ineffective.

Two-thirds of healthcare professionals had never used deceptive nor open-label placebo. Those who had used it, had done so rarely and mostly for non-specific or functional symptoms or for diagnostic purposes.

Conclusions

Despite a generally perceived high effectiveness of deceptive placebo treatments, its prohibition in the UK seems to be in line with general concerns and some strong opposition. Future studies will show if the negative attitude to open-label placebo is justified or if this ethically viable option deserves more consideration.

The Revised Self-Monitoring Scale detects early impairment of social cognition in genetic frontotemporal dementia within the GENFI cohort

BACKGROUND

Although social cognitive dysfunction is a major feature of frontotemporal dementia (FTD), it has been poorly studied in familial forms. A key goal of studies is to detect early cognitive impairment using validated measures in large patient cohorts.

METHODS

We used the Revised Self-Monitoring Scale (RSMS) as a measure of socioemotional sensitivity in 730 participants from the genetic FTD initiative (GENFI) observational study: 269 mutation-negative healthy controls, 193 C9orf72 expansion carriers, 193 GRN mutation carriers and 75 MAPT mutation carriers. All participants underwent the standardised GENFI clinical assessment including the 'CDR® plus NACC FTLD' scale and RSMS. The RSMS total score and its two subscores, socioemotional expressiveness (EX score) and modification of self-presentation (SP score) were measured. Volumetric T1-weighted magnetic resonance imaging was available from 377 mutation carriers for voxel-based morphometry (VBM) analysis.

RESULTS

The RSMS was decreased in symptomatic mutation carriers in all genetic groups but at a prodromal stage only in the C9orf72 (for the total score and both subscores) and GRN (for the modification of self-presentation subscore) groups. RSMS score correlated with disease severity in all groups. The VBM analysis implicated an overlapping network of regions including the orbitofrontal cortex, insula, temporal pole, medial temporal lobe and striatum.

CONCLUSIONS

The RSMS indexes socioemotional impairment at an early stage of genetic FTD and may be a suitable outcome measure in forthcoming trials.
