Abstract

Background:

Dysphagia is a geriatric syndrome often unrecognized or underestimated, and there is a lack of studies in a heterogeneous population in intermediate care (IC) services. This study aims to describe the prevalence of dysphagia and its association with geriatric syndromes in older patients in IC.

Methods:

Prospective cohort study of patients 70 years and older admitted to an IC unit. At admission, the severity of the clinical conditions, comorbidity, delirium, frailty, sarcopenia, nutritional status, and medications were assessed. Each patient was evaluated with the 3-OZ test, and dysphagia was confirmed by a speech therapy consultation. Two multivariable logistic regression models were used to evaluate the association of dysphagia at admission with geriatric syndromes (model 1), along with the severity of illness and admission diagnosis (model 2).

Results:

A total of 455 patients were included. The prevalence of dysphagia was 10% and there was a high prevalence of mild-moderate dysphagia in patients with cognitive impairment and moderate risk of malnutrition. In the univariate analysis, an association was found between dysphagia and sarcopenia, malnutrition, and use of antipsychotics. In Model 1, higher odds of dysphagia were associated with the severity of comorbidity (Odds Ratio 6.49, 95% Confidence Interval: 2.02-20.78), and cognitive impairment (OR 0.91, 95% CI: 0.88-10.62); in Model 2, the severity of clinical conditions-NEWS2 (OR 1.61, 95% CI: 1.23-2.13) was associated with dysphagia, besides the severity of comorbidity and cognitive impairment. In a subset of 300 patients, delirium was also associated with dysphagia.

Conclusions:

The study provides novel information on dysphagia prevalence in patients admitted to an IC unit and its association with geriatric syndromes. Additional research is needed to further define the relationship between geriatric syndromes and dysphagia, and to adequately standardize speech therapist treatments.

Enteral Nutrition II: Nasointestinal and Gastrostomy Feeding

Enteral Nutrition II: Nasointestinal and Gastrostomy Feeding

Enteral nutrition encompasses various methods of delivering nutrition directly to the gastrointestinal (GI) tract, bypassing traditional oral intake. It is particularly beneficial for patients who cannot eat by mouth but have a functioning digestive system. Key methods include nasointestinal feeding, gastrostomy, and jejunostomy, each suited to different clinical scenarios based on the patient's needs and condition.

Enteral Nutrition I: Orogastric and Nasogastric Feeding

Enteral Nutrition I: Orogastric and Nasogastric Feeding

Enteral nutrition delivers nutrients directly to the stomach or small intestine through a tube. This method is appropriate for patients who cannot eat but still have a functioning digestive system. It is also beneficial for individuals with swallowing difficulties, anorexia, malabsorption, or those who have undergone gastrointestinal (GI) surgery.
Orogastric (OG) and nasogastric (NG) feeding are two standard methods used for enteral nutrition. Enteral nutrition is often preferred over...

Esophageal Strictures-II: Clinical Features and Management

Esophageal Strictures-II: Clinical Features and Management

Patients with esophageal strictures often experience a range of symptoms. Initially, they may have difficulty swallowing solid foods, which can progress to include liquids. Additional symptoms may involve chest pain or discomfort, regurgitating food and fluids, heartburn, unintentional weight loss, coughing or choking during meals, and hoarseness.
Healthcare providers should gather a comprehensive medical history and conduct a physical examination for diagnosis. If esophageal stricture is...

Pneumonia I: Introduction

Pneumonia I: Introduction

Pneumonia is an acute respiratory infection that targets the lungs, specifically the alveoli. These tiny air sacs, essential for oxygen exchange, become engorged with pus and fluid, severely hindering breathing, decreasing oxygen absorption, and causing significant pain and discomfort during respiration.
Risk Factors
Various factors influence the likelihood of developing pneumonia. Age plays a crucial role, with infants, children under two, and individuals over 65 at increased risk due to their...

Gastrointestinal Motility Disorders

Gastrointestinal Motility Disorders

Gastrointestinal or GI motility disorders are characterized by irregular gastrointestinal tract movements, disrupting food transit from the mouth to the anus. They are caused by damage or dysfunction in gut muscles or nerves. These disorders can cause symptoms such as severe constipation, diarrhea, abdominal pain, and swallowing difficulties. Disorders can affect any segment of the GI tract and range widely in severity, from common conditions like GERD to life-threatening conditions like...

Gastroesophageal Reflux Disease II: Clinical Features and Management

Gastroesophageal reflux disease, or GERD, is a persistent medical condition that affects many individuals worldwide. Its clinical manifestations can vary greatly, making diagnosis and management challenging for healthcare professionals. The following is a comprehensive overview of the clinical manifestations, assessment, and management strategies for GERD.
Clinical Manifestations
GERD presents itself in a multitude of ways, with symptoms varying from person to person. The hallmark symptoms are...
