[Initial treatment of patients with subjective memory complaints and/or cognitive impairment in primary care: ISSEA Study]

How are people with mild cognitive impairment or subjective memory complaints managed in primary care? A systematic review

BACKGROUND

Primary care is typically the first point of contact in the health care system for people raising concerns about their memory. However, there is still a lack of high-quality evidence and understanding about how primary care professionals (PCPs) currently manage people at higher risk of developing dementia.

OBJECTIVES

To systematically review management strategies provided by PCPs to reduce cognitive decline in people with mild cognitive impairment and subjective memory complaints.

METHOD

A systematic search for studies was conducted in December 2019 across five databases (EMBASE, Medline, PsycInfo, CINAHL and Web of Science). Methodological quality of included studies was independently assessed by two authors using the Mixed Methods Appraisal Tool.

RESULTS

An initial 11 719 were found, 7250 were screened and 9 studies were included in the review. Most studies were self-reported behaviour surveys. For non-pharmacological strategies, the most frequent advice PCPs provided was to increase physical activity, cognitive stimulation, diet and social stimulation. For pharmacological strategies, PCPs would most frequently not prescribe any treatment. If PCPs did prescribe, the most frequent prescriptions targeted vascular risk factors to reduce the risk of further cognitive decline.

CONCLUSION

PCPs reported that they are much more likely to provide non-pharmacological strategies than pharmacological strategies in line with guidelines on preventing the onset of dementia. However, the quality of evidence within the included studies is low and relies on subjective self-reported behaviours. Observational research is needed to provide an accurate reflection of how people with memory problems are managed in primary care.

[Long-term effect analysis of a cognitive stimulation program in mild cognitive impairment elderly in Primary Care: A randomized controlled trial]

OBJECTIVE

To provide evidence about the efficacy of a community health intervention through a cognitive stimulation program at long term in older people with mild cognitive impairment.

DESIGN

Randomized controlled trial (CONSORT group norms).

LOCATION

San José Norte-Centro Primary Care Center and La Caridad Foundation (Zaragoza, Spain).

PARTICIPANTS

Twenty-nine people over 65 years old with a 24-27 MEC score that completed 48 months follow up. They were randomized between the intervention group (15) and the control group (14).

INTERVENTIONS

The intervention was applied in 10 sessions of 45min for 10 weeks using the red notebook tool for mental activation that works memory, orientation, language, praxis, gnosis, calculation, perception, logical reasoning, attention and executive functions.

MAIN MEASUREMENTS

The main outcome variables were MEC-35, Set-test, Barthel index, Lawton-Brody scale, Goldberg anxiety scale and Yesavage geriatric depression scale short form.

RESULTS

Increases of the main result variable over the baseline level of MEC-35 were analyzed. On average, the intervention group obtained higher scores than control: 3.14 points post intervention, 3.76 points after 6 months and 2.26 points more than control group after 12 months. All the differences were statistically significant. After 48 months the intervention group obtained 2 points more than control group. The intervention did not improve verbal fluency, activity daily living and mood.

CONCLUSIONS

Our cognitive stimulation program seems to improve cognitive performance, measured with the variable MEC-35 at post intervention, 6, 12 and 48 months. There is no evidence of improvement in verbal fluency, activity daily livings and mood. Clinicaltrials.gov Identifier: NCT03831061.

[Validation of RUDAS: A screening tool for dementia in Primary Health Care settings]

Objetivo

Validar la escala Rowland Dementia Assessment Scale (RUDAS) como instrumento de cribado de deterioro cognitivo y demencia en atención primaria (AP). Es un test breve, válido para población con bajo nivel educativo formal y fácilmente traducible en entornos multiculturales.

Diseño

Se realizó un estudio epidemiológico descriptivo, de corte transversal, con seguimiento a los 5 años.

Emplazamiento

Centro de salud de atención primaria de O Grove, que atiende a una población de 10.650 habitantes en Pontevedra.

Participantes

Ciento cincuenta personas aleatoriamente seleccionadas, con una edad media de 76,35 ± 7,12 años, bajo nivel educativo, origen predominantemente rural y semirrural y nivel socioeconómico bajo.

Intervención

Se analizó la viabilidad, la aceptabilidad, la validez y la fiabilidad de la escala.

Mediciones principales

RUDAS, Mini Mental State Examination, Clinical Dementia Rating, Índice de Katz, Índice de Barthel, Índice de Lawton y Escala de Depresión Geriátrica de Yesavage.

Resultados

El test fue bien acogido por los pacientes y rápido de aplicar (7,58 ± 2,10 min). El área bajo la curva COR para el diagnóstico de demencia fue 0,983 (IC 95%: 0,97-1,00). Para un punto de corte óptimo de 22,5 presentó una sensibilidad del 89,3% y una especificidad del 100%. El área bajo la curva COR para discriminar personas con DCL de personas con demencia fue 0,965 (IC 95%: 0,91-1,00).

Conclusiones

El RUDAS ha demostrado ser un instrumento viable y eficiente para cribar demencias en AP, libre de influencias educativas y socioculturales. Es especialmente sensible para discriminar población con deterioro cognitivo leve de población con demencia.

[Analysis of the effect of a program of cognitive stimulation in elderly people with normal aging in primary care: Randomized clinical trial]

OBJECTIVE

To provide evidence of the effectiveness of a community health intervention, that includes a cognitive stimulation program, to prevent the deterioration of cognitive abilities in our population of elderly people with normal cognition that are living in the community.

DESIGN

Randomized clinical trial (CONSORT group norms) LOCATION: San José Norte-Centro Health Center and La Caridad Foundation (Zaragoza, Spain).

PARTICIPANTS

201 people aged 65 or older, with a MEC score of at least 28 points, which were randomized between the Intervention group (101) and the Control group (100).

INTERVENTION

The intervention was applied in 10 sessions of 45minutes, one per week. It used materials designed by one of the authors, which addressed the following areas: memory, orientation, language, praxis, gnosis, calculation, perception, logical reasoning, attention-concentration and programming.

MAIN MEASUREMENTS

The main outcome variables were MEC, Set-Test, Barthel and Lawton-Brody.

RESULTS

Increases of the main result variables over their baseline level were analized. For MEC variable, the Intervention group obtained, on average, 1.58 points more than the Control group in the evaluation performed immediately after the intervention. After 6months, the improvement was 1.51 points and after a year, it was of 2.04 points. All these differences were statistically significant. For Set-Test, Barthel and Lawton-Brody variables, no statistically significant differences were observed between Intervention group and Control group.

CONCLUSIONS

Cognitive stimulation with our program is effective to maintain or improve cognitive performance, measured with the variable MEC, our population of elderly people with normal cognition that are living in the community. There is no evidence that this improvement is transferred to the activities of daily life measured with Barthel and Lawton-Brody variables.

[Quality of registration of dementia diagnosis in primary care: The situation in Spain in 2002-2011]

Objetivo

Comprobar el diagnóstico asociado al tratamiento específico para demencia en la historia clínica electrónica de atención primaria (HCE-AP) y analizar los factores asociados a la calidad del registro

Método

Estudio descriptivo de los pacientes con anticolinesterásicos o memantina registrados en la Base para Investigación Farmacoepidemiológica en atención primaria (BIFAP) 2011: 24.575 pacientes entre 2002 y 2011. Los diagnósticos asociados a la primera prescripción de estos fármacos se agruparon en 5 categorías: «demencia», «alteraciones de memoria», «enfermedades relacionadas con demencia», «procesos intercurrentes» y «códigos de conveniencia». Se calculó la prevalencia de cada categoría por edad y sexo en cada año de estudio (IC 95%) y se analizaron asociaciones y tendencia 2002-2011, utilizando diferencias de proporciones para muestras independientes y regresión logística binaria.

Resultados

El 56,5% (IC 95%: 55,8-57,1) de los pacientes tenían asociado código «demencia» a la primera prescripción. Se registró mejor en mujeres (OR: 1,09 [IC 95%: 1,03-1,15]) y al aumentar el tiempo transcurrido (OR: 1,07 [IC 95%: 1,06-1,08] por cada año de seguimiento). Los «códigos de conveniencia» (16,3% [IC 95%: 15,8-16,7]) se utilizaron más en mujeres y ≥ 80 años; las «alteraciones de memoria» (12,4% [IC 95%: 12,0-12,8]), «enfermedades relacionadas» (4,6% [IC 95%: 4,4-4,8]) y «procesos intercurrentes» (10,3% [IC 95%: 9,9-10,6]) más en hombres y < 80 años. De 2002 a 2011 mejoró el uso de «códigos de conveniencia».

Conclusiones

Casi la mitad de los pacientes con anticolinesterásicos o memantina no tienen registrado diagnóstico de demencia en su HCE-AP. El registro mejora al aumentar el tiempo de seguimiento. Se requieren mejoras de la HCE-AP, coordinación asistencial adecuada y actitud activa para aumentar la calidad del registro de demencia.
