One consensual depression diagnosis tool to serve many countries: a challenge! A RAND/UCLA methodology.

OBJECTIVE: From a systematic literature review (SLR), it became clear that a consensually validated tool was needed by European General Practitioner (GP) researchers in order to allow multi-centred collaborative research, in daily practice, throughout Europe. Which diagnostic tool for depression, validated against psychiatric examination according to the DSM, would GPs select as the best for use in clinical research, taking into account the combination of effectiveness, reliability and ergonomics? A RAND/UCLA, which combines the qualities of the Delphi process and of the nominal group, was used. GP researchers from different European countries were selected. The SLR extracted tools were validated against the DSM. The Youden index was used as an effectiveness criterion and Cronbach's alpha as a reliability criterion. Ergonomics data were extracted from the literature. Ergonomics were tested face-to-face. RESULTS: The SLR extracted 7 tools. Two instruments were considered sufficiently effective and reliable for use: the Hospital Anxiety and Depression Scale and the Hopkins Symptoms Checklist-25 (HSCL-25). After testing face-to-face, HSCL-25 was selected. A multicultural consensus on one diagnostic tool for depression was obtained for the HSCL-25. This tool will provide the opportunity to select homogeneous populations for European collaborative research in daily practice.

Which DSM validated tools for diagnosing depression are usable in primary care research? A systematic literature review.

INTRODUCTION: Depression occurs frequently in primary care. Its broad clinical variability makes it difficult to diagnose. This makes it essential that family practitioner (FP) researchers have validated tools to minimize bias in studies of everyday practice. Which tools validated against psychiatric examination, according to the major depression criteria of DSM-IV or 5, can be used for research purposes? METHOD: An international FP team conducted a systematic review using the following databases: Pubmed, Cochrane and Embase, from 2000/01/01 to 2015/10/01. RESULTS: The three databases search identified 770 abstracts: 546 abstracts were analyzed after duplicates had been removed (224 duplicates); 50 of the validity studies were eligible and 4 studies were included. In 4 studies, the following tools were found: GDS-5, GDS-15, GDS-30, CESD-R, HADS, PSC-51 and HSCL-25. Sensitivity, Specificity, Positive Predictive Value, Negative Predictive Value were collected. The Youden index was calculated. DISCUSSION: Using efficiency data alone to compare these studies could be misleading. Additional reliability, reproducibility and ergonomic data will be essential for making comparisons. CONCLUSION: This study selected seven tools, usable in primary care research, for the diagnosis of depression. In order to define the best tools in terms of efficiency, reproducibility, reliability and ergonomics for research in primary care, and for care itself, further research will be essential.

What research agenda could be generated from the European General Practice Research Network concept of Multimorbidity in Family Practice?

BACKGROUND: Multimorbidity is an intuitively appealing, yet challenging, concept for Family Medicine (FM). An EGPRN working group has published a comprehensive definition of the concept based on a systematic review of the literature which is closely linked to patient complexity and to the biopsychosocial model. This concept was identified by European Family Physicians (FPs) throughout Europe using 13 qualitative surveys. To further our understanding of the issues around multimorbidity, we needed to do innovative research to clarify this concept. The research question for this survey was: what research agenda could be generated for Family Medicine from the EGPRN concept of Multimorbidity? METHODS: Nominal group design with a purposive panel of experts in the field of multimorbidity. The nominal group worked through four phases: ideas generation phase, ideas recording phase, evaluation and analysis phase and a prioritization phase. RESULTS: Fifteen international experts participated. A research agenda was established, featuring 6 topics and 11 themes with their corresponding study designs. The highest priorities were given to the following topics: measuring multimorbidity and the impact of multimorbidity. In addition the experts stressed that the concept should be simplified. This would be best achieved by working in reverse: starting with the outcomes and working back to find the useful variables within the concept. CONCLUSION: The highest priority for future research on multimorbidity should be given to measuring multimorbidity and to simplifying the EGPRN model, using a pragmatic approach to determine the useful variables within the concept from its outcomes.

Chronic venous insufficiency. A common health problem in general practice in Greece.

BACKGROUND: A study was carried out in Greece with the aim of assessing the prevalence of chronic venous insufficiency (CVI) in Greece and to discuss the role of general practice in the epidemiology, early diagnosis, and initial management of this disease. DESIGN: a prevalence study was carried out in rural Greece between January 17 and December 30, 1997. SETTING: 13 GPs, 11 of those working in 13 rural primary health centers, 1 in the University Hospital of Heraklion and 1 private sector from different Greek districts were invited to participate in the study. PARTICIPANTS AND METHODS: patients with the following criteria were entered into the study: weight, pain, cramps, burning, itching, formication and swelling. Complete information about patients' history was collected by the general practitioners (GPs) who used a semi-structured questionnaire. The diagnosis of CVI was established with Doppler ultrasound. RESULTS: Data were based on 6,119 questionnaires and GPs observed 4,502 randomly selected patients. The diagnosis of CVI was established in 993 patients and its prevalence was found to be 11.9% in males and 39.8% in females. Varicose veins were the most frequent clinical finding in patients with vein reflux and diabetes mellitus was the most common co-existing disease in males and hypertension in females. CONCLUSIONS: The prevalence of venous insufficiency (VI) appears to be a frequent health problem in general practice in Greece. It requires further investigation in order to explore the observed differences between various groups.

In what extent anemia coexists with cognitive impairment in elderly: a cross-sectional study in Greece.

BACKGROUND: A project aimed at studying the frequency of dementia and depression in the catchment area of the Health Centre of Chrissoupolis (HCCh), Northern Greece, was carried out. This paper reports the association between AD and anemia among the elderly participants in this Greek study. METHODS: Eligible participants were people 65 years or over who were (a) living in the Elderly People's Home (all 48 subjects included); (b) visiting the Open Center for Elderly People during a 20 workday period (75 subjects) and (c) visiting the HCCh for routine medical care. The Mini Mental State Examination (MMSE) was used in assessing the cognitive capacity of the participants. Blood was drawn for serum hematocrit, vitamin B12 and folate determination. RESULTS: The prevalence proportions of possible cognitive impairment among anemic and non-anemic males were 55.6% and 34.4%, respectively (X2 = 5.8, d.f. = 1, p = 0.016). The corresponding proportions in females were 47.5% and 40.1 % (X2 = 1.1, d.f. = 1, p = 0.305). Using logistic regression analysis, age-group (>or= 80 yrs), type of Institute, vitamin B12 and anemia had significant independent associations with possible cognitive impairment. CONCLUSIONS: Anemia is a frequent finding in elderly and it may be a risk factor for dementia, but the extent of the associated deterioration of cognitive impairment or the relation with AD is not known. GPs should be aware of this coexistence and recommend for screening, assaying and treating elderly people.

Dementia and depression: two frequent disorders of the aged in primary health care in Greece.

BACKGROUND: Dementia and depression are very common disorders among elderly people and their presence decreases the well-being of the aged. OBJECTIVES: The purpose of this study was to assess the magnitude of dementia and depression among elderly people living in different settings in the catchment area of the Chrisoupolis health centre (HCCh) in northern Greece. METHODS: A total of 536 patients aged 65 years and over, including 48 subjects living in an old people's home, 75 subjects who were taking part in the activities of the open centre for the elderly and 413 subjects randomly selected from those visiting the HCCh, were interviewed by the primary health care team of the HCCh. Medical and family history data were recorded, while cognitive and mood disorders were assessed by using the Mini Mental State Examination and Geriatric Depression Screening Scale. RESULTS: At the time of the examination, 37.6% of the men and 41.6% of the women showed various degrees of cognitive impairment, while 29.9% of the women and 19.6% of the men showed mild to moderate depression. Diabetes mellitus and hypertension frequently were found to co-exist with depression and dementia. CONCLUSION: The results reaffirm that there is a high prevalence of the studied mental disorders in older patients in the out-patient setting in Greece. A set of recommendations to Greek GPs has now been formulated, with specific emphasis on the use of different screening tools and the appropriate treatment of the most frequently co-existing chronic diseases.
