Queda em idosos: uma abordagem prática

Autoria SCIMAGO INSTITUTIONS RANKINGS

RESUMO

Antecedentes:

As quedas são um grande problema de saúde pública, uma vez que são uma importante causa de morbidade e mortalidade. A avaliação do risco de queda e a prescrição de intervenções preventivas podem ser tarefas desafiadoras.

Objetivo:

Estudo visa sintetizar as informações mais relevantes sobre o tema “quedas em idosos” e apresentar uma visão crítica e uma abordagem da prática clínica neste tema.

Métodos:

Em março de 2022, foi feita uma revisão bibliográfica no Pubmed, utilizando-se os termos “fall elder”, fall prevention”, “fall risk”, com os seguintes parâmetros s: 5 anos, revisão, revisão sistemática, meta-análise, diretrizes práticas.

Resultados:

Há inúmeros fatores de risco para quedas que podem ser agrupados em diferentes domínios (psicossocial, demográfico, condições clínicas, uso de medicamentos, comportamental, ambiental). A avaliação clínica de um idoso propenso a queda deve incluir a identificação de fatores de risco por meio da história e exame físico e identificação do risco de queda por meio de um instrumento de avaliação como velocidade da marcha, teste de alcance funcional, timed up and go, teste de equilíbrio de Berg, escala miniBEST. As estratégias de prevenção de quedas podem ser únicas ou múltiplas, sendo a atividade física a mais citada. Tecnologias podem ser usadas para detectar e prevenir quedas.

Conclusão:

Uma abordagem sistemática ao paciente idoso em risco de queda é possível, deve ser realizada e pode impactar na prevenção de quedas.

Single measure tools
Test	Purpose	Instructions	Interpretation	Cut-off for falls
Functional reach test²¹	Measures the maximum distance a person can reach forward while standing in a fixed position	The patient is instructed to stand next to a wall and position the arm that is closer to the wall (but not touching) at 90 degrees of shoulder flexion with a closed fist. The assessor Instructs the patient to “Reach as far as you can forward without taking a step.” The location of the 3rd metacarpal is recorded at beginning and ending position, and the scores are the difference between these values. Three trials are done, final score is the average value of the best 2 results.	Smaller distances = worse performance	< 18,5cm²²
Gait velocity²⁴	Measures the walking speed in a comfortable, natural speed	A distance of 3-10 meters is measured, with or without an addition distance for acceleration and deceleration. Individual is timed once the foot touches the initial path and is stopped once it reached the end of the path (without the acceleration and deceleration distance). Two trials are measured	Higher gait velocity = better functional mobility Normal functional mobility = gait speed > 1,0m/sec	<0,7m/s²⁶ <1,0 m/s²⁰
Berg Balance Scale²⁷	Assesses balance	14 items, that include static and dynamic balance tasks Each item points 0-4 Total scale score 0-56	Higher scores = better performance	45-49 points²⁹
Timed up and Go (TUG)³⁰	Assesses balance, mobility, walking ability	The patient sits on a standard armchair, and is instructed to stand up, walk on a comfortable speed along a l3 meters line, turn around at the line, walk back to the chair, and sit down. The test ends when the patient’s buttocks touch the seat.	Shorter time = better performance	>11 sec²⁰ >13 sec¹⁸
miniBEST test³¹	Assesses balance, mobility, walking ability	14 items, that include dynamic balance tasks, walking tasks and TUG. Each item point 0-2 Total score 0-28	Higher scores = better performance	>19 points³³ 17-25 points³² (age dependent)

Intervention
Exercises (supervised, unsupervised, or both)	gait; balance and functional training; strength/resistance exercises; flexibility exercises; 3D training (e.g. Tai Chi); general physical activity; endurance training or others.
Medication (review and target)	vitamin D and calcium supplementation.
Medication (review and target)	medication withdrawal, dose reduction or increase, substitution or provision (antihypertensives, cardiovascular agents, drugs used in diabetes, anti-parkinson drugs, anti-dementia drugs, antidepressants, antipsychotic/neuroleptic drugs, anxiolytics/hypnotics/sedatives, other)
Surgery	cataract extraction, pacemaker provision, podiatric surgery or others.
Management of urinary incontinence	e.g. assisted toileting, bladder retraining, prompted voiding, pelvic floor exercises, antispasmodics
Fluid or nutrition therapy	Fluid therapy to restore the volume and composition of the body fluids to normal with respect to water- electrolyte balance. Nutrition therapy to improve health status of an individual by adjusting the quantities, qualities, and methods of nutrient intake.
Psychological individual or group	Cognitive (behavioural) interventions and others.
Environment/Assistive technology	Furnishings and adaptations to homes and other premises, aids for personal mobility, aids for communication, information and signalling, body worn aids for personal care and protection, social environment.
Social environment	staff ratio, staff training, service model, telephone support, caregiver training, home care services, others.
Knowledge	pamphlets, information, booklets/sheets, videos, lectures.

Risk factor		Intervention
Non-modifiable conditions	Age Female gender	Raising awareness of the increased risk of falls
Medical conditions	Chronic diseases	Improving the individualized management of chronic diseases
	Depression	Improving the individualized management of depression Exercises
