Mental health in older adult recipients of primary care services: is depression the key issue? Identification, treatment and the general practitioner

Objectives Mental health services for older people in primary care are relatively underdeveloped. This study has sought to determine the nature and extent of mental health problems in older people presenting to primary care and to compare this with the detection and management of mental health problems by the primary health care team (PHCT). Method Participants were patients aged 65 years and above attending a representative inner city general practice. Screening tools included the General Health Questionnaire (GHQ-28), Hospital Anxiety and Depression Scale (HADS), Mini Mental State Examination (MMSE). The PHCT used a brief checklist to rate participants for the presence of mental health problems. Follow-up interviews using the Geriatric Mental State (GMSA), Cambridge Examination for Mental Disorders in the Elderly (CAMDEX)-cognitive subscale (CAMCOG), National Adult Reading Test (NART), were carried out. Results A high level of psychological morbidity was identified at screening (48.1%). There was a considerable degree of agreement between the HADS and GMSA, and the MMSE and GMSA at follow-up. Agreement rates between the PHCT and initial screening tools were low suggesting under-recognition of mental health problems at primary care level by the PHCT. Contributory factors included: short consultation times with a concentration on physical symptoms; few patients presenting explicitly with mental health problems; few decisions to treat or refer patients; and the general practitioners tended to monitor, or defer decisions. Conclusions This study found lower levels of severe mental health problems, especially depression, than reported elsewhere, but higher prevalence of psychological distress. High levels of physical and mental health co-morbidity were found. These findings suggest that planning for primary care services needs to adopt a flexible assessment model. The development of effective, time-limited protocols and screening tools to assist the PHCT in improving their identification rates is recommended. This needs to be supported by the availability of appropriate treatments for the psychological distress. Copyright (C) 2002 John Wiley Sons, Ltd.
