“…DOSS is officially a validated instrument for screening delirium and does not diagnose whether a patient is delirious, but it has a high sensitivity of 97% 33,46. DOSS has never been validated for patients with dementia, but geriatricians have diagnosed delirium in this patient category 32,47…”

BackgroundDelirium in hip fractured patients is a frequent complication. Dementia is an important risk factor for delirium and is common in frail elderly. This study aimed to extend the previous knowledge on risk factors for delirium and the consequences. Special attention was given to patients with dementia and delirium.MethodsThis is a retrospective cohort study performed in the Amphia Hospital, Breda, the Netherlands. A full electronic patient file system (Hyperspace Version IU4: Epic, Inc., Verona, WI, USA) was used to assess data between January 2014 and September 2015. All patients presented were aged ≥70 years with a hip fracture, who underwent surgery with osteosynthesis or arthroplasty. Patients were excluded in case of a pathological or a periprosthetic hip fracture, multiple traumatic injuries, and high-energy trauma. Patient and surgical characteristics were documented. Postoperative outcomes were noted. Delirium was screened using Delirium Observation Screening Scale and dementia was assessed from medical notes.ResultsOf a total of 566 included patients, 75% were females. The median age was 84 years (interquartile range: 9). Delirium was observed in 35%. Significant risk factors for delirium were a high American Society of Anesthesiology score, delirium in medical history, functional dependency, preoperative institutionalization, low hemoglobin level, and high amount of blood transfusion. Delirium was correlated with a longer hospital stay (P=0.001), increased association with complications (P<0.001), institutionalization (P<0.001), and 6-month mortality (P<0.001). Patients with dementia (N=168) had a higher delirium rate (57.7%, P<0.001) but a shorter hospital stay (P<0.001). There was no significant difference in the 6-month mortality between delirious patients with (34.0%) and without dementia (26.3%).ConclusionElderly patients with a hip fracture are vulnerable for delirium, especially when the patient has dementia. Patients who underwent an episode of delirium were at increased risk for adverse outcomes.

“…The Delirium Observation Screening scale score was also obtained in all patients (surgical and nonsurgical) three times a day. 19 With a Delirium Observation Screening scale score >3, the geriatrician was consulted to confirm the diagnosis of POD according to the Diagnostic and Statistical Manual of Mental Disorders, fourth edition, criteria. 1 Patients who developed delirium underwent a comprehensive physical examination with additional laboratory testing to identify a possible underlying cause for delirium, such as sepsis, electrolyte imbalance, or pharmacologic abnormalities, and were treated if necessary.…”

“…Severity of delirium was measured by the Delirium Observation Screening (DOS) scale . While originally developed as a screening tool for delirium, the DOS scale has also been shown to be able to measure the severity of delirium . It is a 13‐item observational scale of verbal and non‐verbal behavior with a total score of 13.…”
