[Validation of RUDAS: A screening tool for dementia in Primary Health Care settings]. / Validación del RUDAS como instrumento de cribado de población con demencia en atención primaria.

OBJECTIVE: To validate Rowland Dementia Assessment Scale (RUDAS), as an instrument for the screening of people with dementia and cognitive impairment in Primary Health Care (PHC). RUDAS is a brief cognitive test, appropriate for people with minimum completed level of education and easily adaptable to multicultural contexts. For these reason it could be a good instrument for dementia screening in PHC. DESIGN: Cross-sectional descriptive epidemiological study with a five-year follow up. LOCATION: O Grove PHC centre, Galicia, Spain (covering a population of 10,650 individuals). OUTCOME MEASURES: RUDAS; Mini Mental State Examination; Clinical Dementia Rating; Katz, Barthel and Lawton Indexes; MMSE and Yesavage Geriatric Depression Scale. PARTICIPANTS: A total of 150 older adults (mean age 76.35±7.12years) randomly selected, from a low sociocultural and economical background and mainly rural and semirural origin. INTERVENTION: RUDAS viability in PHC was checked, and its psychometric properties assessed: reliability, sensitivity, specificity, positive and negative predictive values. RESULTS: RUDAS application was brief (7.58±2.10min) and well accepted. RUDAS area under receiver operating characteristic (ROC) curve for the detection of dementia was 0.983 (95% confidence interval (CI): 0.97-1.00) for an optimal cut-off point of 22.5, with sensitivity of 89.3%, and a specificity of 100%. Area under ROC curve for discriminating dementia from mild cognitive impairment was 0.965 (95%CI: 0.91-1.00). CONCLUSIONS: RUDAS test is fit for dementia screening in PHC and it is especially sensitive to discriminate PWD from people with MCI.

Health care contact prior to suicide attempts in older adults. A field study in Galicia, Spain.

INTRODUCTION: Older people have the highest suicide rates in the world. In turn, they have the lowest rates of suicide attempts. Many studies have found greater health contact, especially with general practitioner, prior to suicidal behaviour in this age group. Less information is availbale about prior contact with other health services. OBJECTIVE: The objective of the study is to know the characteristics of contact with all levels of health services, prior to a suicide attempt in people over 65 years of age in a defined population. MATERIAL AND METHODS: Along the period January 2015 to December 2017, all persons over 65 years of age admitted by suicide attempt to emergency room in the health area of Santiago de Compostela were interviewed. The interview included a psychiatric evaluation and the collrection of relevant clinical and sociodemographic variables, in particular, data on prior contact with health services. RESULTS: 80 suicide attempts were recorded, which represents an incidence of 35.3 / 100,000. The average age of our sample was 74.85 ± 7 years, the ratio between male: female was 2: 3. 61.3% had visited their general practitioner the month prior to the attempt, 72.5% had visited a health centre. On the other hand, 41.3% were not under the follow up of Mental Health services. CONCLUSIONS: The facts hat two out of three people over 65 years who commit suicide attempt in our area visit their general practitioner the previous month and 90% visit a health service along the previous three months, raise the question of wheter preventive measures of suicide could take place beyond the scope of Primary Care.

Validity across translations of short survey psychiatric diagnostic instruments: CIDI-SF and CIS-R versus SCID-I/NP in four European countries.

OBJECTIVES: The aims of the study are: first, to compare two short diagnostic instruments, CIDI-SF and CIS-R, with respect to the structured clinical interview for non-patient (SCID-I/NP) for anxiety and depressive disorders; and second, to evaluate the influence of four languages, Italian, Romanian, Spanish and French, on the concordance tests. METHODS: A total of 120 participants from Italy and Romania, 119 from Spain and 141 from France (N = 500) were recruited randomly in a local primary care research centre (GPs or medical centres). The instruments were administered during a unique session: the lay instruments by students in psychology and the SCID by experienced psychiatrists. Kappa, sensitivity/specificity/negative (NPV) and positive predictive values (PPV), ROC curve (AUC) and the Youden Index (Y) were calculated. RESULTS: Results were better for the CIDI-SF than the CIS-R for anxious disorders, depressive disorders and any of them. The results were identical to that obtained by the CIDI 3.0 for the three categories and constant across the languages except for depressive disorders in Romania and France. CONCLUSIONS: CIDI-SF is a cost-effective instrument and could be easily integrated into health surveys; its performance values are better across languages than values proposed by the CIS-R and could be increased by inclusion of few additional information.
