Hospitals rely on a wide range of clinical and non-clinical staff to deliver safe and effective care. One of the key allied health professional roles is the Speech and Language Therapist (SLT), who assesses and treats problems with speech, language, communication, and swallowing.
This article is the second instalment in our series exploring clinical roles within the allied health professional team.
SLTs work with patients of all ages across hospital wards, outpatient clinics, and community settings. They provide interventions that support recovery, improve quality of life, and help patients safely manage eating, drinking, and communicating.
What is a Speech and Language Therapist?
A Speech and Language Therapist is a registered healthcare professional trained to assess, diagnose, and treat difficulties with:
- Speech and spoken language
- Communication, including understanding and expression
- Swallowing and safe eating
SLTs apply evidence-based interventions tailored to each patient’s needs, often in collaboration with medical, nursing, and allied health colleagues.
Common Conditions and Communication Difficulties
SLTs frequently work with patients who have communication or swallowing issues caused by:
- Stroke or brain injury
- Neurological conditions such as Parkinson’s disease, Multiple Sclerosis, or Motor Neurone Disease
- Dementia
- Head and neck cancer
- Respiratory difficulties
Typical communication difficulties include:
- Dysphasia (aphasia): Difficulty using or understanding spoken and written language, often following stroke or brain injury
- Dysarthria: Weakness or reduced coordination of the facial and oral muscles, affecting speech clarity
SLTs may introduce alternative communication strategies such as gestures, word-and-picture charts, symbols, or communication devices to support patients’ interaction.
Assessing and Treating Swallowing Problems
SLTs also help patients who have difficulties with eating and drinking, known as dysphagia. Symptoms can include coughing, choking, or a “chesty” voice after swallowing. Causes may include muscle weakness or obstructions in the food pipe.
Typical interventions include:
- Swallow assessments to identify safe foods and drinks
- Modifying diets (e.g., pureed foods or thickened liquids)
- Advising on safe postures while eating or drinking to reduce risk of aspiration
- Supporting alternative feeding methods such as nasogastric (NG) tubes or PEG feeding when required
SLTs monitor progress closely and adjust interventions to ensure safe nutrition and hydration for each patient.
Main Duties and Responsibilities
SLTs carry out a range of clinical duties, including:
- Conducting comprehensive assessments of speech, language, communication, and swallowing
- Developing and delivering individualised treatment plans for patients
- Monitoring patient progress and modifying interventions as needed
- Advising patients, families, and carers on safe communication and feeding strategies
- Responding to urgent referrals from wards or clinics
- Diagnosing communication or swallowing difficulties and identifying potential underlying health conditions
- Supporting safe discharge by liaising with community SLTs for ongoing care
Typical Day in a Hospital Setting
A hospital-based SLT’s day varies depending on the service and patient needs. A typical day may involve:
- Reviewing patient caseloads and medical histories
- Attending wards to assess new or ongoing patients
- Providing therapy sessions for speech, language, and swallowing difficulties
- Adjusting treatment plans based on patient progress
- Preparing patients for discharge with strategies and resources for continued care
- Coordinating with dietitians when swallowing issues affect nutrition
Role Within the Healthcare Team
SLTs work alongside a broad range of healthcare professionals to provide safe, coordinated care. They regularly interact with:
- Doctors and nurses
- Dietitians
- Occupational and physiotherapists
- Patients, families, and carers
Their work ensures patients can communicate effectively, eat and drink safely, and participate fully in their care and recovery.
Conclusion
Speech and Language Therapists are clinical professionals who assess, diagnose, and treat communication and swallowing difficulties.
By providing tailored interventions, SLTs help patients regain independence, reduce health risks, and improve overall quality of life, making their role a critical part of the multidisciplinary healthcare team.
