Unplanned readmissions are often caused by patients with multiple comorbidities and functional impairment [1]. This subgroup partly consists out of patients presenting with nonspecific complaints. It is known that patients presenting with such complaints are a vulnerable population and characterized by their high comorbidity, polypharmacy and functional impairment [2]. These patients typically complain of “weakness and fatigue” and if they have a serious illness it is either not recognised or recognised too late, resulting in more adverse events and poorer outcomes when compared to patients with specific complaints such as “chest pain” [2–6].
