Assessment of the information provided by the medical specialist on Alzheimer's disease and that retained by the patient caregivers.

INTRODUCTION

There is evidence of insufficient communication abilities by medical specialists as well as of the limited retentive capacities of patients with Alzheimer disease (AD) and their caregivers. The main reasons for this include the personal limitations of the physician, as well as external, emotional and social-cultural factors associated with the patients and their caregivers. The aim of this study is to compare the clinical information on AD provided by the physicians and that perceived by caregivers and to assess factors associated with differences in perception.

PATIENTS AND METHODS

We carried out an observational national multicentre study based on questionnaires assessing the information provided by the physician and that retained by the caregiver for 17 items of information. The study involved 61 researchers and included a total of 679 patients who met the selection criteria. We evaluated the factors associated with the difference in perception of the information that was transmitted.

RESULTS

Participating caregivers had a mean age of 57.2 ± 14.8 years, with an average care time of 27.6 ± 28.0 months. Approximately half (50.9%) were children of the AD patient and most lived in the same household (64.9%). Caregivers assigned significantly higher ratings to information on concept of disease, aetiology, pathogenesis, dosage and treatment recommendations and adherence, while doctors assigned significantly higher ratings to information related to demystification and correcting preconceived notions, possible complications, adverse events and/or iatrogenesis, family associations, and emotional/psychological support to caregivers (P<.05). Concordance between the information provided and that received was classified between poor and weak (inter-rater agreement ≤ 0.27). The degree of disease progression using the Global Deterioration Scale (GDS) was a factor significantly associated with professional-carer information discrepancy (P=.002).

CONCLUSIONS

Many areas of information showed large differences in perception between physicians and caregivers of AD patients, which highlights the need to improve the communication process in order to achieve higher quality.
