Multimodal home-based rehabilitation intervention after discharge from inpatient geriatric rehabilitation (GeRas): study protocol for a multicenter randomized controlled trial.

BACKGROUND: Geriatric rehabilitation aims to maintain the functional reserves of older adults in order to optimize social participation and prevent disability. After discharge from inpatient geriatric rehabilitation, patients are at high risk for decreased physical capacity, increased vulnerability, and limitations in mobility. As a result, ageing in place becomes uncertain for a plethora of patients after discharge from geriatric rehabilitation and effective strategies to prevent physical decline are required. Collaboration between different health-care providers is essential to improve continuity of care after discharge from inpatient geriatric rehabilitation. The aim of this study is to evaluate the effectiveness of a multi-professional home-based intervention program (GeRas) to improve functional capacity and social participation in older persons after discharge from inpatient geriatric rehabilitation. METHODS: The study is a multicenter, three-arm, randomized controlled trial with a three-month intervention period. Two hundred and seventy community-dwelling older people receiving inpatient geriatric rehabilitation will be randomized with a 1:1:1 ratio to one of the parallel intervention groups (conventional IG or tablet IG) or the control group (CG). The participants of both IGs will receive a home-based physical exercise program supervised by physical therapists, a nutritional recommendation by a physician, and social counseling by social workers of the health insurance company. The collaboration between the health-care providers and management of participants will be realized within a cloud environment based on a telemedicine platform and supported by multi-professional case conferences. The CG will receive usual care, two short handouts on general health-related topics, and facultative lifestyle counseling with general recommendations for a healthy diet and active ageing. The primary outcomes will be the physical capacity measured by the Short Physical Performance Battery and social participation assessed by the modified Reintegration to Normal Living Index, three months after discharge. DISCUSSION: The GeRas program is designed to improve the collaboration between health-care providers in the transition from inpatient geriatric rehabilitation to outpatient settings. Compared to usual care, it is expected to improve physical capacity and participation in geriatric patients after discharge from inpatient geriatric rehabilitation.

Frailty index and its association with the onset of postoperative delirium in older adults undergoing elective surgery.

BACKGROUND: The association of frailty based on the accumulation of deficits with postoperative delirium (POD) has been poorly examined. We aimed to analyze this association in older patients undergoing elective surgery. METHODS: Preoperative data was used to build a 30-item frailty index (FI) for participants of the PAWEL-study. Delirium was defined by a combination of I-CAM and chart review. Using logistic regressions models we analysed the association between frailty and POD adjusting for age, sex, smoking, alcohol consumption, education and type of surgery. RESULTS: Among 701 participants (mean age 77.1, 52.4% male) median FI was 0.27 (Q1 0.20| Q3 0.34), with 528 (75.3%) frail participants (FI ≥ 0.2). Higher median FI were seen in orthopedic than cardiac surgery patients (0.28 versus 0.23), and in women (0.28 versus 0.25 in men). Frail participants showed a higher POD incidence proportion (25.4% versus 17.9% in non-frail). An increased odds for POD was observed in frail versus non-frail participants (OR 2.14 [95% CI 1.33, 3.44], c-statistic 0.71). A 0.1 increment of FI was associated with OR 1.57 [95% CI 1.30, 1.90] (c-statistic 0.72) for POD. No interaction with sex or type of surgery was detected. Adding timed-up-and-go-test and handgrip strength to the FI did not improve discrimination. CONCLUSION: Our data showed a significant association between frailty defined through a 30-item FI and POD among older adults undergoing elective surgery. Adding functional measures to the FI did not improve discrimination. Hence, our preoperative 30-item FI can help to identify patients with increased odds for POD. TRIAL REGISTRATION: PAWEL and PAWEL-R (sub-) study were registered on the German Clinical Trials Register (number DRKS00013311 and DRKS00012797).

Expectations of nursing personnel and physicians on dementia training : A descriptive survey in general hospitals in Germany and Greece.

BACKGROUND: The number of dementia training programs in hospital settings is steadily increasing. The way training sessions are designed influences the way the learning content is implemented in practice. To develop a successful training it is important to meet the needs of the target group; however, not much is known about staff preferences and expectations relevant to future dementia training programs in hospitals in Germany and Greece. OBJECTIVE: The aim of this survey was to explore staff training needs relevant to the topic of dementia, in general hospitals in Germany and Greece. This study analyzed the interests of staff members, preferences and expectations with respect to dementia training. MATERIAL AND METHODS: This was a descriptive survey based on a 54-item questionnaire conducted with 61 nursing staff, head nurses and physicians (Germany: n = 25, Greece: n = 36) recruited from 5 hospitals (Germany: n = 3, Greece: n = 2). Parts of the questionnaire explored participants' previous education regarding dementia and their expectations towards future dementia programs. RESULTS: Although staff attendance in educative programs was high in the last 5 years for both countries, participation in dementia training programs was low (Germany 24%, Greece 5.5%). Additionally, the great majority of participants were willing to be trained in future dementia training programs (Germany 96%, Greece 100%). Employees from both countries expect increased clinical skills as a result of participation in such training programs. In Greece, staff members hope for better handling of people with dementia, while in Germany, concrete practical advice is preferred. CONCLUSION: There seems to be a strong willingness to participate in further dementia training programs where not only theoretical knowledge is provided but also practical advice.

Outcomes of a bladder preservation technique in female patients undergoing pelvic exenteration surgery for advanced gynaecological tumours.

INTRODUCTION AND HYPOTHESIS: The purpose of the study was to report the feasibility of the bladder preservation technique (BPT) during pelvic exenteration for primary advanced gynaecological pelvic tumours (PRSGT) as an alternative for continent urinary diversion. METHODS: Sixteen consecutive female patients underwent BPT during PRSGT. Median age was 50.8 years (range 37-65). Tumours included cervical (5 patients), corpus/vaginal (9), and ovarian (2) carcinomas. In resectable tumours, the excision of the distal ureters and the posterior bladder wall with an inverted "V" incision into the trigone down to the vaginal wall was performed with bladder blood and nerve supply preservation. The remaining mobilized leaflets were fixed to the psoas muscle/sacral promontory. Average follow-up was 34 months (range 24-108). Follow-up parameters included postoperative continence grade (full [no pads], stress incontinence grade I [1-2 pads], and grade II [>2 pads]), urinary tract infections, micturation problems/residual urine, ureteric reflux as well as patients' global satisfaction (PGS). RESULTS: All surgeries were done successfully. One patient developed a vesicovaginal fistula 4 weeks postoperatively and was managed conservatively. Fifteen patients (94 %) were able to empty their bladders postoperatively. Prolonged full continence was reported from 8 patients (50 %), incontinence grade I in 3 (18.8 %), and grade II in 5 (31.3 %). Two patients (incontinence grade II) developed cystoceles necessitating transvaginal bladder neck suspension with a fascia lata sling and were continent postoperatively. Another patient (6 %) underwent re-excision of a recurrent pelvic tumour necessitating intermittent self-catheterization. Postoperative hydronephrosis (grade I-II) was observed in 4 patients (25 %) and vesico-ureteral reflux (grade IV) in 4 (25 %) without the need for intervention. PGS and willingness to recommend their procedure to others were favourable. CONCLUSIONS: In patients for whom complete bladder resection is not indicated for oncological reasons, BPT during PRSGT with ureteric reimplantation is feasible and safe and provides good functional results as well as patient global satisfaction. Lower tract surgeries could be safely carried out afterward. Long-term functional results support durable good PGS.

Outcomes of a Delirium Prevention Program in Older Persons After Elective Surgery: A Stepped-Wedge Cluster Randomized Clinical Trial.

Importance: Delirium significantly worsens elective surgery outcomes and costs. Delirium risk is highest in elderly populations, whose surgical health care resource consumption (50%) exceeds their demographic proportion (15% to 18%) in high-resource countries. Effective nonpharmacologic delirium prevention could safely improve care in these vulnerable patients, but data from procedure-specific studies are insufficiently compelling to drive changes in practice. Delirium prevention approaches applicable to different surgical settings remain unexplored. Objective: To examine whether a multifaceted prevention intervention is effective in reducing postoperative delirium incidence and prevalence after various major surgical procedures. Design, Setting, and Participants: This stepped-wedge cluster randomized trial recruited 1470 patients 70 years and older undergoing elective orthopedic, general, or cardiac surgery from November 2017 to April 2019 from 5 German tertiary medical centers. Data were analyzed from December 2019 to July 2021. Interventions: First, structured delirium education was provided to clinical caregivers at each site. Then, the study delirium prevention team assessed patient delirium risk factors and symptoms daily. Prevention was tailored to individual patient needs and could include: cognitive, motor, and sensory stimulation; meal companionship; accompaniment during diagnostic procedures; stress relaxation; and sleep promotion. Main Outcomes and Measures: Postoperative delirium incidence and duration. Results: Of 1470 included patients, 763 (51.9%) were male, and the median (IQR) age was 77 (74-81) years. Overall, the intervention reduced postoperative delirium incidence (odds ratio, 0.87; 95% CI, 0.77-0.98; P = .02) and percentage of days with delirium (intervention, 5.3%; control, 6.9%; P = .03). The effect was significant in patients undergoing orthopedic or abdominal surgery (odds ratio, 0.59; 95% CI, 0.35-0.99; P = .047) but not cardiac surgery (odds ratio, 1.18; 95% CI, 0.70-1.99; P = .54). Conclusions and Relevance: This multifaceted multidisciplinary prevention intervention reduced postoperative delirium occurrence and days with delirium in older patients undergoing different elective surgical procedures but not cardiac procedures. These results suggest implementing this delirium prevention program will improve care and outcomes in older patients undergoing elective general and orthopedic procedures.

Presurgical Screening Improves Risk Prediction for Delirium in Elective Surgery of Older Patients: The PAWEL RISK Study.

Introduction: The number of elective surgeries for patients who are over 70 years of age is continuously growing. At the same time, postoperative delirium (POD) is common in older patients (5-60%) depending on predisposing risk factors, such as multimorbidity, cognitive impairment, neurodegenerative disorders and other dementing disorders, and precipitating factors, such as duration of surgery. Knowledge of individual risk profiles prior to elective surgery may help to identify patients at increased risk for development of POD. In this study, clinical and cognitive risk factors for POD were investigated in patients undergoing various elective cardiac and non-cardiac surgeries. Methods: The PAWEL study is a prospective, interventional trial on delirium prevention. At baseline, 880 inpatients at five surgical centers were recruited for sub-sample PAWEL-R. Multimodal assessments included clinical renal function, medication, American Society of Anesthesiologists (ASA) Physical Status Classification System, geriatric and cognitive assessments, which comprised the Montreal Cognitive Assessment Scale (MoCA), Trail-making Test, and Digit Span backward. Delirium incidence was monitored postoperatively by the Confusion Assessment Method (CAM) and a chart review for up to a week or until discharge. Multivariate regression models and Chi-square Automatic Interaction Detectors (CHAID) analyses were performed using delirium incidence as the primary outcome. Results: Eighteen risk factors were investigated in elective cardiovascular and orthopedic or general surgery. A total of 208 out of 880 patients (24%) developed POD. A global regression model that included all risk variables predicted delirium incidence with high accuracy (AUC = 0.81; 95% CI 0.77, 0.85). A simpler model (clinical and cognitive variables; model CLIN-COG) of 10 factors that only included surgery type, multimorbidity, renal failure, polypharmacy, ASA, cut-to-suture time, and cognition (MoCA, Digit Span backward, and preexisting dementia), however, exhibited similar predictive accuracy (AUC = 0.80; 95% CI 0.76, 0.84). Conclusion: The risk of developing POD can be estimated by preoperative assessments, such as ASA classification, expected cut-to-suture time, and short cognitive screenings. This rather efficient approach predicted POD risk over all types of surgery. Thus, a basic risk assessment including a cognitive screen can help to stratify patients at low, medium, or high POD risk to provide targeted prevention and/or management strategies for patients at risk.

Patient safety, cost-effectiveness, and quality of life: reduction of delirium risk and postoperative cognitive dysfunction after elective procedures in older adults-study protocol for a stepped-wedge cluster randomized trial (PAWEL Study).

BACKGROUND: Postoperative delirium is a common disorder in older adults that is associated with higher morbidity and mortality, prolonged cognitive impairment, development of dementia, higher institutionalization rates, and rising healthcare costs. The probability of delirium after surgery increases with patients' age, with pre-existing cognitive impairment, and with comorbidities, and its diagnosis and treatment is dependent on the knowledge of diagnostic criteria, risk factors, and treatment options of the medical staff. In this study, we will investigate whether a cross-sectoral and multimodal intervention for preventing delirium can reduce the prevalence of delirium and postoperative cognitive decline (POCD) in patients older than 70 years undergoing elective surgery. Additionally, we will analyze whether the intervention is cost-effective. METHODS: The study will be conducted at five medical centers (with two or three surgical departments each) in the southwest of Germany. The study employs a stepped-wedge design with cluster randomization of the medical centers. Measurements are performed at six consecutive points: preadmission, preoperative, and postoperative with daily delirium screening up to day 7 and POCD evaluations at 2, 6, and 12 months after surgery. Recruitment goals are to enroll 1500 patients older than 70 years undergoing elective operative procedures (cardiac, thoracic, vascular, proximal big joints and spine, genitourinary, gastrointestinal, and general elective surgery procedures). DISCUSSION: Results of the trial should form the basis of future standards for preventing delirium and POCD in surgical wards. Key aims are the improvement of patient safety and quality of life, as well as the reduction of the long-term risk of conversion to dementia. Furthermore, from an economic perspective, we expect benefits and decreased costs for hospitals, patients, and healthcare insurances.

A multicentre RCT on community occupational therapy in Alzheimer's disease: 10 sessions are not better than one consultation.

OBJECTIVE: To compare the benefits and harms of a Dutch 10-session Community Occupational Therapy programme for patients with Alzheimer's disease with the impact of a one session consultation at home in German routine healthcare. DESIGN: A seven-centre, parallel group, active controlled randomised controlled trial. Patients and carers were not masked. Assessors were fully blind for treatment allocation for one of two primary-outcome measurements. SETTING: Patients' homes. PARTICIPANTS: Patients with mild to moderate Alzheimer's disease (Mini-Mental State Examination 14-24), living in the community with primary carer available and without severe depression or behavioural symptoms, were eligible. INTERVENTIONS: Experimental 10 home visits within 5 weeks by an occupational therapist, educating patients in the performance of simplified daily activities and in the use of aids to compensate for cognitive decline; and educating carers in coping with behaviour of the patient and in giving supervision to the patient. Control one home visit including individual counselling of patient and carer and explanation of a leaflet on coping with dementia in daily life. OUTCOME MEASURES: The primary outcome was the patient's daily functioning measured with the Interview of Deterioration in Daily activities in Dementia and the Perceive, Recall, Plan and Perform System of Task Analysis. Assessments were at baseline, 6, 16 and 26 weeks, with a postal assessment at 52 weeks. RESULTS: 141 patients were 1:1 randomised to the experimental (N=71) and control group (N=70). Data for 54 and 50 participants were analysed. Patients' daily functioning did not differ significantly between the experimental and control group at week 6, 16, 26 or 52 and remained stable over 26 weeks in both groups. No adverse events were associated with the interventions. CONCLUSIONS: In German healthcare, a Dutch 10-session community occupational therapy was not better than a one-session consultation for the daily functioning of patients with Alzheimer's disease. Further research on the transfer of complex psychosocial is needed. International Clinical Trials Registry Platform DRKS00000053; Funded by the German Federal Ministry of Health.
