Randomized clinical study with a control group for assessing the decrease in the incidence of pneumonia, in a 12-month follow-up, in older people with cognitive impairment, risk of bronchial aspiration, risk of malnutrition and dependence to perform basic activities of daily living, through the design and implementation of an educational program. to the caregivers of these patients.
Introduction: The number of people over 65 years of age is increasing, observing an older population worldwide. In the year 2050 there will be 2,000 million, this situation is due to medical and technological advances, in addition to the declining birth rate. People live longer, but there is also a higher incidence of chronic diseases, associated with age. Among them, neurodegenerative diseases stand out, due to the dependence they entail, as well as the risk of situations such as episodes of bronchial aspiration, which can cause pneumonia that will require hospital admissions, as well as the risk of malnutrition and dependence to carry out basic activities of daily life. .
Most of these patients are cared for at home by their caregivers, who, in addition to not knowing how to care for oropharyngeal dysphagia, the situation of prolonged fatigue can generate overload and anxiety for the caregiver.
Objective: To evaluate the decrease in the incidence of pneumonia, in a 12-month follow-up, in older adults with cognitive impairment, risk of bronchial aspiration, risk of malnutrition and dependence to carry out basic activities of daily living, through the design and implementation of a educational program. to the caregivers of these patients.
Methodology: A sequential exploratory mixed study will be carried out. For the design of the educational intervention, a descriptive qualitative study will be carried out with focus groups of caregivers and the recommendations of the Health Literacy model will be followed. To evaluate the efficacy of this intervention, a pre-post intervention randomized clinical trial with a control group will be carried out. The sample will be 178 couples made up of caregivers (formal or informal non-professional caregivers) and people over 65 who are in their care. The study will be carried out at the Parc Sanitari Per Virgili in Barcelona from May 2019 to March 2023. The main variables and study instruments are the incidence and admissions for pneumonia, as well as its delay in onset in older people, measured by Clinical history, cognitive impairment, measured with the Pfeiffer test, the risk of bronchial aspiration measured with the volumetric viscosity exploratory method test (V-VST), the risk of malnutrition measured with the Mini Nutritional Assessment short-form scale (MNA- SF). In addition to the anxiety and overload of their caregivers, measured with the Goldberg and Zarit scale.

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| Control group | Active Comparator | Conventional information received by caregivers. The speech therapist comes to the room to pass the Volume viscosity exploratory method test (V-VST) Test and after confirming dysphagia, informs the patient of the test result and delivers a booklet of recommendations. |
|
| Intervention group | Experimental | A 45-minute session, hygienic-dietary training, with visual support and work materials where three specific interventions are explained: textures for solids and liquids, safety postures to reduce the risk of bronchial aspiration, and oral hygiene. In addition, tools are offered to caregivers so that they can identify situations of anxiety and overload, as well as guidelines for social support. |

| Variable: Malnutrition risk. | Continuous quantitative variable. It is defined as "an unbalanced nutritional state resulting from insufficient nutrient intake to meet normal physiological requirements". Measured with Scale Mini Nutritional Assessment-Short Form (MNA-SF). Through the Clinic History and own questionnaire. Scale to assess malnutrition (maximum score of 14 points). 12-14 points: normal nutritional status; 8-11 points: risk of malnutrition; 0-7 points: malnutrition. |

|---|---|---|
| Variable: Level of Oropharyngeal Dysphagia. | Discrete quantitative variable. Coded as (level 1: severe dysphagia, novel 2: moderate-severe dysphagia, level 3: moderate dysphagia, level 4: mild-moderate dysphagia, novel 5: mild dysphagia, level 6: diet-modified functional swallowing, level 7, swallowing normal). It is defined as, "systematically rating the functional severity of dysphagia based on an objective assessment and making recommendations for the level of diet, level of independence, and type of nutrition" Measured with the Dysphagia Outcome and Severity Scale (DOSS). |

| Variable: Cognitive impairment. | Discrete quantitative variable. Cognitive impairment is defined according to the Medical Subject Headings (MeSH) descriptor, as "the decrease or deterioration of mental and/or intellectual function". Measured with Pfeiffer test. Pfeiffer scale, It consists of 10 items. Between 0-2: it is considered normal; Between 3-4: mild cognitive impairment Between 5-7: moderate cognitive impairment; More than 8 errors: severe cognitive impairment. | At study entry; At 3 months after entering the study; At 12 months after entering the study |
| Variable: Risk of Bronchoaspiration. | Discrete quantitative variable. It is defined as "A type of pulmonary inflammation resulting from the aspiration of food, liquid, or gastric contents into the upper respiratory tract." Measured with the volume-viscosity swallow test (V-VST). Test performed to detect if there is aspiration due to dysphagia. The signs are: cough, decrease in basal oxygen saturation greater than 5%, change in tone of voice and/or alteration in efficacy such as insufficient lip seal, oral or pharyngeal residuals and fractional swallowing. The test consists of three textures (water, nectar and pudding) with three volumes (5 ml, 10 ml and 20 ml). It begins by administering (5ml of nectar texture), if any sign is found that compromises safety, it will not go to a higher volume or lower viscosity. It is concluded that there is no dysphagia when there are no signs of safety or altered efficacy at any time of the test. | Before entering the study. |

Values from 0 points (total dependency) to 100 points (independent) < 20 total dependency; 20-35 severe dependency; 40-55 Moderate dependency; ≥ 60 mild dependency; 100 independent | At study entry; At 3 months after entering the study; At 12 months after entering the study |
| Variable: Anxiety. | Qualitative variable.
