RESUMO
BACKGROUND: Valvular heart diseases are frequent and increasing in prevalence. Minimally invasive heart valve surgery embedded in an interdisciplinary enhanced recovery after surgery (ERAS) program may have potential benefits with regard to reduced length of stay and improved patient reported outcomes. However, no prospective randomized data exist regarding the superiority of ERAS program for the patients' outcome. METHODS: We aim to randomize (1:1) a total of 186 eligible patients with minimally invasive heart valve surgery to an ERAS program vs. standard treatment at two centers including the University Medical Center Hamburg-Eppendorf, Germany, and the University Hospital Augsburg, Germany. The intervention is composed out of pre-, peri-, and postoperative components. The preoperative protocol aims at better preparation for the operation with regard to physical activity, nutrition, and psychological preparedness. Intraoperative anesthesiologic and surgical management are trimmed to enable an early extubation. Patients will be transferred to a specialized postoperative anesthesia care unit, where first mobilization occurs 3 h after surgery. Transfer to low care ward will be at the next day and discharge at the fifth day. Participants in the control group will receive treatment as usual. Primary endpoints include functional discharge at discharge and duration of in-hospital care during the first 12 months after index surgery. Secondary outcomes include health-related quality of life, health literacy, and level of physical activity. DISCUSSION: This is the first randomized controlled trial evaluating the effectiveness of an ERAS process after minimally invasive heart valve surgery. Interprofessional approach is the key factor of the ERAS process and includes in particular surgical, anesthesiological, physiotherapeutic, advanced nursing, and psychosocial components. A clinical implication guideline will be developed facilitating the adoption of ERAS model in other heart teams. TRIAL REGISTRATION: The study has been registered in ClinicalTrials.gov ( NCT04977362 assigned July 27, 2021).

BACKGROUND: In elderly patients following surgery, postoperative delirium (POD) is the most frequent complication and is associated with negative outcomes. The 2017 European Society of Anaesthesiology guideline on POD aims to improve patient care by implementing structured delirium prevention, diagnosis and treatment. However, these recommendations, especially systematic delirium screening, are still incompletely adopted in clinical practice. The aim of this study was to evaluate the feasibility and acceptance of validated delirium screening tools and to identify barriers to their implementation on nonintensive care unit wards. METHODS: Screening rates, as well as practicability, acceptance and the interprofessional handling of positive results, were assessed for each group. Screening rates were calculated as a percentage of the total potential testing episodes completed (up to 15 per patient). Patients were considered eligible when aged 65âyears and above. Barriers and motivating factors were assessed in a mixed method approach by utilising questionnaires and focus group discussions. INTERVENTION: In a 3-month phase, a guideline-compliant screening protocol involving screening for POD three times daily for 5 days following surgery was introduced in five wards: both the 4-item assessment test (4AT) and the nursing delirium screening scale (NuDESC) were used. Before commencing the study and again after 6âweeks, medical staff of the respective wards underwent a 45âmin training session. RESULTS: Of a total of 3183 potential testing episodes, 999 (31.4%) were completed, with more NuDESC observational tests (43%) than 4AT bedside tests completed (20%). The 4AT was considered more difficult to integrate into daily working routines, it took longer to administer, and nurses felt uncomfortable conducting the screening (53 vs. 13%). Screening results indicating delirium were often not discussed within the team (47%), and nurses felt that often such results were not taken seriously by physicians (54%). CONCLUSION: The observational NuDESC showed a higher completion rate than the bedside 4AT, although overall testing rates were low. The necessary time needed to conduct the screening, the negative reactions by patients, insufficient team communication and a lack of initiation of any therapy were identified as major barriers in the implementation of the guideline-compliant screening protocol. For all staff, further education and awareness of the importance of POD diagnosis and treatment might improve the screening rates. The NuDesc received better results concerning acceptance, practicability and introduction into daily work routine, leading to higher screening rates compared with the 4AT. The latter instrument, which was intended to be used rather selectively or when POD is suspected, might therefore not be suitable for guideline-compliant regular and repeated screening for POD.
