Abstract

A 78-year-old patient with a laryngectomy and a background of bronchiectasis experienced frequent hospital admissions due to pulmonary exacerbations. Standard care would be to trial a positive expiratory pressure (PEP) device to assist with secretion removal, however, no adaptor could be found to contour the patient’s tracheostoma. A 3D printed patient-specific PEP adaptor was created, facilitating regular secretion clearance via PEP therapy. Frequency of hospital admissions and outcomes of disease-specific questionnaires (St. George’s Respiratory Questionnaire (SGRQ) and Leicester Cough Questionnaire (LCQ)) were evaluated at three and six months.

After six months of device use, the patient had not experienced a pulmonary exacerbation or required an admission, whilst demonstrating clinically significant improvements in both SGRQ (58.98 vs. 66.3/100) and LCQ (11.27 vs. 13.27/21) scores. Collaboration between consumers, clinicians and engineers can support the delivery of personalised healthcare and improve quality of life for patients with pulmonary conditions.
