Evaluation of the effectiveness of delirium prevention care protocol for the patients with hip fracture: A randomised controlled study

This study aimed to investigate the effectiveness of a delirium prevention care protocol on pain, functional status, sleep quality and delirium prevention in patients with hip fractures.The development of delirium following hip fracture is common among older patients. According to the National Institute for Health and Care Excellence, 30% of delirium cases are preventable. The prevention of delirium, a multifactorial syndrome, can be achieved through a multicomponent care protocol that targets specific risk factors for delirium.A randomised controlled study was conducted according to the CONSORT 2010 guidelines. The Clinical Trial Registry number is NCT04188795.A total of 84 patients were assigned to two groups by block randomisation. The intervention group (n = 41) received nursing care according to a protocol and the control group (n = 43) received standard nursing care. Study data were collected using the demographic information form, the Confusion Assessment Method-Intensive Care Unit (CAM-ICU), the Barthel Index, the Mini Nutritional Assessment-short form and the Richards-Campbell Sleep Questionnaire (RCSQ). The pain of the patients was assessed by using a Visual Analog Scale (VAS).The mean age of the patients was 80.6 years (standard deviation 8.0; range 65.0- 97.5 years), and the percentage of the male patients were 36.3%. No statistically significant differences were found between the groups in terms of pain and functional status in the preoperative period, on the first postoperative day, or in the predischarge period (p > 0.05 for each). The sleep quality of patients in the intervention group was significantly better than in the control group for all three time measurements (p < 0.05 for each). While 15% of patients in the control group developed delirium, no patient in the intervention group developed delirium (x2 =6.486, p = 0.026).This study demonstrated that a delirium prevention care protocol may reduce the incidence of delirium and improve sleep quality.The study highlighted that nurses can contribute to preventing patients' delirium using nonpharmacologic and independent nursing interventions.
