Psychiatric screening in geriatric primary care: should it be for depression alone?

Collaborative Care for Psychiatric Disorders in Older Adults: A Systematic Review

OBJECTIVE

To evaluate the mode of implementation, clinical outcomes, cost-effectiveness, and the factors influencing uptake and sustainability of collaborative care for psychiatric disorders in older adults.

DESIGN

Systematic review.

SETTING

Primary care, home health care, seniors' residence, medical inpatient and outpatient.

PARTICIPANTS

Studies with a mean sample age of 60 years and older.

INTERVENTION

Collaborative care for psychiatric disorders.

METHODS

PubMed, MEDLINE, Embase, and Cochrane databases were searched up until October 2016. Individual randomized controlled trials and cohort, case-control, and health service evaluation studies were selected, and relevant data were extracted for qualitative synthesis.

RESULTS

Of the 552 records identified, 53 records (from 29 studies) were included. Very few studies evaluated psychiatric disorders other than depression. The mode of implementation differed based on the setting, with beneficial use of telemedicine. Clinical outcomes for depression were significantly better compared with usual care across settings. In depression, there is some evidence for cost-effectiveness. There is limited evidence for improved dementia care and outcomes using collaborative care. There is a lack of evidence for benefit in disorders other than depression or in settings such as home health care and general acute inpatients. Attitudes and skill of primary care staff, availability of resources, and organizational support are some of the factors influencing uptake and implementation.

CONCLUSIONS

Collaborative care for depressive disorders is feasible and beneficial among older adults in diverse settings. There is a paucity of studies on collaborative care in conditions other than depression or in settings other than primary care, indicating the need for further evaluation.

Prevalence of somatoform disorders and medically unexplained symptoms in old age populations in comparison with younger age groups: a systematic review

OBJECTIVE

To review current knowledge regarding the prevalence of somatization problems in later life by level of caseness (somatoform disorders and medically unexplained symptoms, MUS) and to compare these rates with those in middle-aged and younger age groups.

METHOD

A systematic search of the literature published from 1966 onwards was conducted in the Pubmed and EMBASE databases.

RESULTS

Overall 8 articles, describing a total of 7 cohorts, provided data of at least one prevalence rate for somatoform disorders or MUS for the middle-aged (50-65 years) or older age (≥65 years) group. Prevalence rates for somatoform disorders in the general population range from 11 to 21% in younger, 10 to 20% in the middle-aged, and 1.5 to 13% in the older age groups. Prevalence rates for MUS show wider ranges, of respectively 1.6-70%, 2.4-87%, and 4.6-18%, in the younger, middle, and older age groups, which could be explained by the use of different instruments as well as lack of consensus in defining MUS.

CONCLUSION

Somatoform disorders and MUS are common in later life, although the available data suggest that prevalence rates decline after the age of 65 years. More systematic research with special focus on the older population is needed to understand this age-related decline in prevalence rates.

[Medically unexplained and somatoform complaints and disorders in the elderly: a systematic review of the literature]

OBJECTIVE

To provide a systematic overview of the research concerning the frequency of medically unexplained, somatoform complaints and disorders in the elderly, their risk factors, comorbidity, course, management in primary and secondary care, and psychotherapy.

METHOD

We evaluated 248 clinical and randomized trials, reviews, meta-analyses and practice guidelines for adult samples identified from "PubMed" and "PsycInfo" using the search terms "somatoform" OR "medically unexplained" OR "somatization" OR "somatisation" in combination with other terms for their relevance for the elderly. Other relevant trials were identified from the references from these publications.

RESULTS

Medically unexplained, somatoform complaints and disorders occur in older persons and are more frequent in elderly women than in elderly men. Although many studies found no increased frequency of somatoform complaints in the elderly, based on present research we cannot draw final conclusions concerning the frequency of somatoform disorders and complaints in the elderly, and we cannot give evidence based recommendations for their treatment in primary and secondary care and psychotherapy.

DISCUSSION

This situation results from the special problems encountered in the diagnosis of somatoform complaints and disorders in the elderly, from problems in conceptualisation also found in younger adults, and from the lack of research concerning treatment focussed solely on the old and very old.

Design and sample characteristics of the PRISM-E multisite randomized trial to improve behavioral health care for the elderly

OBJECTIVE

To describe the design of the Primary Care Research in Substance Abuse and Mental Health for Elderly (PRISM-E) study and baseline characteristics of the randomized primary care patients with mental health problems and at-risk alcohol use.

METHOD

Adults aged 65 and older were screened at primary care clinics from 10 study sites throughout the United States. Those diagnosed for depression, anxiety, and/or at-risk alcohol consumption were randomized to either integrated or enhanced referral care.

RESULTS

Of the 23,828 participants, 14% had a positive assessment for depressive and/or anxiety disorders, and 6% had at-risk alcohol consumption diagnoses. Among patients with mental health diagnoses, there was a higher preponderance of younger ages, women, and ethnic minorities. Among patients with at-risk drinking, there was a higher preponderance of younger ages, Whites, and men.

DISCUSSION

These findings indicate the need for screening in primary care and for engaging older adults in treatment.

Integrating clinical nurse specialists into the treatment of primary care patients with depression

OBJECTIVE

To examine the effectiveness of integrating generalist and specialist care for veterans with depression.

METHOD

We conducted a randomized trial of patients screening positive for depression at two Veterans Affairs Medical Center general medicine clinic firms. Control firm physicians were notified prior to the encounter when eligible patients had PRIME-MD depression diagnoses. In the intervention firm, a mental health clinical nurse specialist (CNS) was to: design a treatment plan; implement that plan with the primary care physician; and monitor patients via telephone or visits at two weeks, one month and two months. Primary outcomes (depressive symptoms, patient satisfaction with health care) were collected at 3 and 12 months.

RESULTS

Of 268 randomized patients, 246 (92%) and 222 (83%) completed 3- and 12-month follow-up interviews. There were no between-group differences in depressive symptoms or satisfaction at 3 or 12 months. The intervention group had greater chart documentation of depression at baseline (63% versus 33%, p = 0.003) and a higher referral rate to mental health services at 3 months (27% versus 9%, p = 0.019). There was no difference in the rate of new prescriptions for, or adequate dosing of, anti-depressant medications. In 40% of patients, CNSs disagreed with the PRIME-MD depression diagnosis, and their rates of watchful waiting were correspondingly high.

CONCLUSIONS

Implementing an integrated care model did not occur as intended. Experienced CNSs often did not see the need for treatment in many primary care patients identified by the PRIME-MD. Integrating integrated care models in actual practice may prove challenging.

Correlates of subjective health in older adults: a meta-analysis

Age-associated changes of subjective health and associations of subjective health with physical health, functional health, and mental health were meta-analyzed in older adults (M age > 60 years). An age-associated decline of subjective health, which was stronger in old-old samples than in young-old samples, was found. Subjective health was correlated with the indicators of objective health, but the association with physical health was stronger than with functional health. Correlations of subjective health with physical health and functional health were lower in the old-old than in the young-old samples, whereas associations of subjective health with mental health were stronger in older samples. Furthermore, the size of the association between subjective and objective health varied by the method of assessment of objective health, showing highest associations with symptom checklists and results of medical examinations due to strict protocols.

Getting the questions right: an example of loss of validity during transfer of a brief screening approach for depression in the elderly

Screening for depression in the elderly has been advocated to improve detection and management. This article summarises the trend towards briefer screening instruments, and the integration of mental health screening with other assessments. The study aimed to validate a single question depression screen which has previously shown adequate sensitivity and specificity in a new context: a multi-faceted assessment instrument used by nurse practitioners within a community sample of over 75 year olds. The GMS-AGECAT computerised interview assessment was used as a 'gold standard' to determine the accuracy of the depression question in this new setting. Three hundred and twenty-eight patients were screened by their own nurse practitioners, of whom 100 consenting patients underwent a further interview with a research assistant using the GMS-AGECAT. The prevalence of depression was 30%, the sensitivity of the question was 67%, and its specificity 60% (compared with 88% and 71% previously). Responses indicating disability and loneliness were more closely correlated with depression than the depression screen itself. Relevant factors may include: the derivation of the question, the effect of a different sample, altered reliability when used by multiple interviewers, differing patient expectations, and the wording and context of the question within the multi-faceted screening instrument. Depression screening questions need repeated validation when used in different contexts. Patient and staff expectations may influence how screening instruments are used in practice in a way that may also alter reliability. Further studies are needed to establish the causes of loss of validity when screening approaches are used in new settings.

Patient’s and general practitioner’s different views on patient’s depression

Differences between patient's and general practitioner's view on patient's depressive syndromes was investigated in a prospective birth cohort study of 70 year old people (n=1032) in Turku City, Finland. The aim of this study was to find factors which are typical for people having depressive syndromes in old age and help medical and nursing staff to identify depressive syndromes in the general aged people. The study consisted of a structural postal questionnaire including patient's perception of his depression, an interview made by a public health nurse included mini-mental state examination (MMSE) and the self-rating depression scale of Zung, an interview and comprehensive clinical examination by a general practitioner. Out of the 847 persons who completed the depression test, 12.6% showed symptoms of depressive syndrome. The views of those who scored more than 45 points in the Zung depression scale on their own depressiveness differed from the general practitioner's opinion. In the general practitioner's examination and interview 58% of the subjects had no depressive symptoms even though the test results indicated that they were depressed. The depressed group stood out most clearly in two questions: Do you feel you are needed and do you have future plans? When the same questions were repeated 5 years later, the difference was still statistically significant between depressed and non-depressed group (P<0.0001). The data indicated that medical and nursing staff should take self-assessments seriously and look into them in closer detail. General practitioners and nurses should learn to ask right questions and use short depression scale systematically in order to facilitate the detection of depressive syndromes.

Geriatric psychiatry in primary care. A focus on ambulatory settings

Considering how tightly interwoven are the strands of mental and physical health in the fabric of late life, it would be unwise for psychiatrists and primary care physicians to continue to insist on separately tracing and mending frayed old threads, each in mostly one direction, occasionally irritated by the shortcomings in the others work, and only occasionally seeking or offering assistance. As reflected in their help-seeking behavior and their characterization of suffering, the elderly often do not see, or do not choose to recognize, the theoretical and professional distinctions we hold so dear. Acknowledging the impact of the unmet needs of elderly patients, and respecting the wisdom of their choices, primary care physicians and psychiatrists have an obligation to work together more effectively. Improved mental health in our geriatric patients will require major efforts in the areas of research, public education, health care funding, and community resource development, as well as in individual patient care. Medical disciplines working in isolation or in opposition will not attenuate these obstacles effectively.
