Evaluating the Use of an App in Pleural Disease: Algorithm-supported Clinical Decision Making Versus Usual Care (APPLAUS)
Evaluating the Use of an App in Pleural Disease: Algorithm-supported Clinical Decision Making Versus Usual Care: a Multicentre, Stepped-wedge Cluster-randomised Controlled Trial to Reduce Number of Days in Hospital.
Pleural disease is a group of conditions that affect the membrane around the lungs. These conditions-fluid around the lungs, infections, cancer, and collapsed lung-are common and can cause serious illness. They often lead to long hospital stays, emergency admissions, and reduced quality of life. In Denmark and worldwide, the number of patients with pleural disease is rising, and the treatment is costly for the healthcare system.
How long patients stay in the hospital depends on the type of pleural disease. Some stay less than a week, while others remain for several weeks, especially if complications occur. Research shows that early diagnosis and treatment based on clinical guidelines can shorten hospital stays and improve outcomes.
In the UK, many hospitals have created dedicated pleural clinics run by specialists. These clinics help ensure that patients receive fast, consistent, and evidence based care, and they have reduced the number of days patients spend in hospital. In Denmark, however, such clinics are rare. A recent national survey showed that many Danish hospitals do not follow current pleural disease guidelines, and many lack clear pathways for diagnosing and treating these patients. As a result, patients may receive suboptimal care.
This project aims to close that gap. The goal is to develop an easy to use, guideline based decision tool that supports doctors in emergency, medical, and surgical departments. The tool will guide clinicians from the moment a patient arrives until discharge, helping them choose the right tests and treatments at the right time. By making expert knowledge accessible to non specialists, the project hopes to improve patient care, reduce complications, and shorten hospital stays.
Ultimately, the project seeks to ensure that all patients with pleural disease in Denmark receive fast, safe, and evidence based treatment-no matter where they are admitted.
