What is BCST?

Behavioral Cough Suppression Therapy (BCST) is a non-pharmacological intervention designed to treat chronic cough by employing behavioral techniques. It involves patient education, counseling, and specific exercises aimed at altering cough-inducing behaviors. 

BCST focuses on identifying and modifying the triggers and reinforcing factors that sustain chronic cough, thus breaking the cycle of cough perpetuation.

BCST is part of a broader field of behavioral therapy, which has a long-standing history of treating psychosomatic and habitual conditions. Over time, BCST has been refined through clinical trials and empirical research, establishing its efficacy and protocols.

How does BCST work?

Behavioral therapy in general focuses on modifying maladaptive behaviors through conditioning techniques. It is widely used to treat various psychological and behavioral disorders by extinguishing negative behaviors, reinforcing desired behaviors, and at times, creating new behavior pathways..

In the context of cough suppression, behavioral therapy techniques are adapted to target the specific behaviors and thought patterns associated with chronic cough:

• Educating patients about the nature of their cough and potential triggers.
• Teaching controlled breathing techniques and vocal exercises to reduce cough reflex sensitivity
• Using cognitive-behavioral strategies to address anxiety or stress that may exacerbate coughing.
• Implementing habit reversal training to replace coughing with alternative, non-harmful behaviors.

The effectiveness of BCST can be attributed to its impact on both psychological and physiological mechanisms. It helps patients understand the role of psychological factors such as anxiety, stress, and hypervigilance in perpetuating chronic cough. Cognitive restructuring helps patients reframe their thoughts about coughing (e.g., learning to interpret throat irritation and the “urge-to-cough” as a neutral sensation that does not need to be acted on) and reducing the anticipatory anxiety that often triggers cough episodes.

Further, through controlled breathing and vocal exercises, BCST directly influences the physiological aspects of coughing. While the exact mechanisms of neurobiologic action are not known, there is emerging evidence suggesting BCST likely changes central brain mechanisms mediating inhibitory motor cough pathways. BCST exercises help desensitize the cough reflex and improve respiratory control. Additional habit reversal techniques can interrupt the automatic cough response, allowing the body to reset its coughing threshold.

Clinical Application and Integration

The integration of BCST into clinical practice offers an exciting opportunity for medical professionals that are exposed to patients who present with persistent cough symptoms. It can be employed as a standalone treatment or as part of a multimodal approach in conjunction with pharmacological treatments. For many patients with chronic cough or those unresponsive to traditional treatments, BCST provides an alternative that can lead to substantial improvements.

Patient Engagement and Empowerment

BCST emphasizes patient involvement and self-management, empowering individuals to take an active role in their treatment. This approach can lead to higher patient satisfaction and better adherence to treatment protocols. Patients now have access to sophisticated cough detection and tracking tools such as CoughPro to monitor and measure their cough over time. Medical professionals can leverage this to foster a collaborative relationship with patients, enhancing overall treatment outcomes - (medical professionals reading this can go over to the specialized section of this website).
