[Prehabilitation, Well Prepared for Abdominal Surgery]. / Prehabilitatie voor kwetsbare ouderen, goed voorbereid voor abdominale chirurgie.

Older, frail patients have an increased risk of post-operative complications resulting in loss of function, dependency, reduced quality of life and mortality. Possibly, prehabilitation can improve postoperative outcomes. The aim of this clinical lesson was to present the current evidence for prehabilitation in abdominal surgery with a specific focus on the geriatric population. Prehabilitation seems to be acceptable and feasible for older patients. Especially multidimensional prehabilitation programs seem promising. Moreover, tailor-made exercise programs have been shown to have a positive effect on postoperative complications. However, none of this has yet been conclusively proven. More studies are needed to evaluate the effect of prehabilitation in the frail surgical population.

PREsurgery thoughts - thoughts on prehabilitation in oncologic gynecologic surgery, a qualitative template analysis in older adults and their healthcare professionals.

PURPOSE: This study aimed to reveal information that can be used for composing a prehabilitation program tailored to elderly gynecological oncological patients and is applicable to healthcare professionals. We investigated possible content and indications for prehabilitation, and what potential barriers might exist. MATERIALS AND METHODS: Because of the primary exploratory study aim, inductive thematic template analysis on semi-structured interviews with gynecologic oncological patients aged ≥60 years and healthcare professionals were used. RESULTS: 16 patients and 20 healthcare professionals were interviewed. Three themes important for prehabilitation were found: (1) "Motivation," (2) "Practical issues and facilitators," and (3) "Patient-related factors." A short time interval between diagnosis and surgery was reported as a potential barrier for prehabilitation. Given components for a tailor-made prehabilitation program are: (1) The first contact with a nurse who screens the patients, gives tailor-made advice on prehabilitation and keeps patients motivated and supports them mentally; (2) If patients are referred to a more extensive/supervised program, this should preferably be arranged close to a patients' home. CONCLUSION: Based on our findings, an outline of a patient-tailored prehabilitation program was developed. The main important themes for prehabilitation were "Motivation," "Practical issues and facilitators," and "Patient-related factors."IMPLICATIONS FOR REHABILITATIONPatients and healthcare professionals are positive about prehabilitation.Main themes for designing a prehabilitation program are "Motivation," "Practical issues and facilitators," and "Patient-related factors."Nursing staff can play a key role in prehabilitation.It is important to screen patients for specific impairments to obtain a tailor-made prehabilitation program.For some patients, general advice on prehabilitation might be sufficient, while others may need more supervision.The time interval between diagnosis and surgery is often short and is perceived as a potentially significant barrier for an effective prehabilitation program.

Loss of skeletal muscle density during neoadjuvant chemotherapy in older women with advanced stage ovarian cancer is associated with postoperative complications.

OBJECTIVE: To assess the association between loss of lumbar skeletal muscle mass and density during neoadjuvant chemotherapy (NACT) and postoperative complications after interval cytoreductive surgery (CRS) in older patients with ovarian cancer. MATERIALS AND METHODS: This multicenter, retrospective cohort study included patients aged 70 years and older with primary advanced stage ovarian cancer (International Federation of Gynecology and Obstetrics stage III-IV), treated with NACT and interval CRS. Skeletal muscle mass and density were retrospectively assessed using Skeletal Muscle Index (SMI) and Muscle Attenuation (MA) on routinely made Computed Tomography scans before and after NACT. Loss of skeletal muscle mass or density was defined as >2% decrease per 100 days in SMI or MA during NACT. RESULTS: In total, 111 patients were included. Loss of skeletal muscle density during NACT was associated with developing any postoperative complication ≤30 days after interval CRS both in univariable (Odds Ratio (OR) 3.69; 95% Confidence Interval (CI) 1.57-8.68) and in multivariable analysis adjusted for functional impairment and WHO performance status (OR 3.62; 95%CI 1.27-10.25). Loss of skeletal muscle density was also associated with infectious complications (OR 3.67; 95%CI 1.42-9.52) and unintended discontinuation of adjuvant chemotherapy (OR 5.07; 95%CI 1.41-18.19). Unlike loss of skeletal muscle density, loss of skeletal muscle mass showed no association with postoperative outcomes. CONCLUSION: In older patients with ovarian cancer, loss of skeletal muscle density during NACT is associated with worse postoperative outcomes. These results could add to perioperative risk assessment, guiding the decision to undergo surgery or the need for perioperative interventions.

Low preoperative skeletal muscle density is predictive for negative postoperative outcomes in older women with ovarian cancer.

OBJECTIVE: To determine the predictive value of lumbar skeletal muscle mass and density for postoperative outcomes in older women with advanced stage ovarian cancer. METHODS: A multicenter, retrospective cohort study was performed in women ≥ 70 years old receiving surgery for primary, advanced stage ovarian cancer. Skeletal muscle mass and density were assessed in axial CT slices on level L3. Low skeletal muscle mass was defined as skeletal muscle index < 38.50 cm2/m2. Low skeletal muscle density was defined as one standard deviation below the mean (muscle attenuation < 22.55 Hounsfield Units). The primary outcome was any postoperative complication ≤ 30 days after surgery. Secondary outcomes included severe complications, infections, delirium, prolonged hospital stay, discharge destination, discontinuation of adjuvant chemotherapy and mortality. RESULTS: In analysis of 213 patients, preoperative low skeletal muscle density was associated with postoperative complications ≤ 30 days after surgery (Odds Ratio (OR) 2.83; 95% Confidence Interval (CI) 1.41-5.67), severe complications (OR 3.01; 95%CI 1.09-8.33), infectious complications (OR 2.79; 95%CI 1.30-5.99) and discharge to a care facility (OR 3.04; 95%CI 1.16-7.93). Preoperative low skeletal muscle mass was only associated with infectious complications (OR 2.32; 95%CI 1.09-4.92). In a multivariable model, low skeletal muscle density was of added predictive value for postoperative complications (OR 2.57; 95%CI 1.21-5.45) to the strongest existing predictor functional impairment (KATZ-ADL ≥ 2). CONCLUSION: Low skeletal muscle density, as a proxy of muscle quality, is associated with poor postoperative outcomes in older patients with advanced stage ovarian cancer. These findings can contribute to postoperative risk assessment and clinical decision making.

Risk assessment for postoperative outcomes in a mixed hospitalized gynecological population by the Dutch safety management system (Veiligheidsmanagementsysteem, VMS) screening tool 'frail elderly'.

PURPOSE: Frailty is associated with a higher risk for negative postoperative outcomes. This study aimed to determine the association between the screening tool of the Dutch safety management system, Veiligheidsmanagementsysteem (VMS) 'frail elderly' and postoperative complications in a gynecological population. METHODS: This cohort study included women aged 70 years or older, who were scheduled for any kind of gynecological surgery. VMS screening data (including risk for delirium, falling, malnutrition, and functional impairment) were extracted from the electronic patient records. VMS score could range between 0 and 4 patients with a VMS score of one or more were considered frail. Data on possible confounding factors and complications within 30 days after surgery, classified with the Clavien-Dindo classification, were collected. Regression analysis was performed. RESULTS: 157 women were included with a median age of 74 years (inter quartile range 71-79). Most patients underwent prolapse surgery (52%) or hysterectomy (31%). Forty-one patients (26%) experienced any postoperative complication. Sixty-two patients (39%) were considered frail preoperatively by the VMS screening tool. Frailty measured with the VMS screening tool was not independently associated with postoperative complications in multivariable analysis (Odds ratio 1.18; 95% CI 0.49-2.82). However, a recent fall in the last 6 months (n = 208) was associated with postoperative complications (Odds ratio 3.90; 95% CI 1.57-9.66). CONCLUSION: An independent association between frailty, determined by the VMS screening tool 'Frail elderly', and postoperative complications in gynecological surgery patients could not be confirmed. A recent fall in the last 6 months seems associated with postoperative complications.

The Comparative Risk of Delirium with Different Opioids: A Systematic Review.

OBJECTIVE: There is substantial evidence that the use of opioids increases the risk of adverse outcomes such as delirium, but whether this risk differs between the various opioids remains controversial. In this systematic review, we evaluate and discuss possible differences in the risk of delirium from the use of various types of opioids in older patients. METHODS: We performed a search in MEDLINE by combining search terms on delirium and opioids. A specific search filter for use in geriatric medicine was used. Quality was scored according to the quality assessment for cohort studies of the Dutch Cochrane Institute. RESULTS: Six studies were included, all performed in surgical departments and all observational. No study was rated high quality, one was rated moderate quality, and five were rated low quality. Information about dose, route, and timing of administration of the opioid was frequently missing. Pain and other important risk factors of delirium were often not taken into account. Use of tramadol or meperidine was associated with an increased risk of delirium, whereas the use of morphine, fentanyl, oxycodone, and codeine were not, when compared with no opioid. Meperidine was also associated with an increased risk of delirium compared with other opioids, whereas tramadol was not. The risk of delirium appeared to be lower with hydromorphone or fentanyl, compared with other opioids. Numbers used for comparisons were small. CONCLUSION: Some data suggest that meperidine may lead to a higher perioperative risk for delirium; however, high-quality studies that compare different opioids are lacking. Further comparative research is needed.

The Effect of Treatment of Anemia with Blood Transfusion on Delirium: A Systematic Review.

OBJECTIVES: Treating the precipitating factors of delirium is the mainstay of the prevention and treatment of delirium. We aim to investigate the role of anemia and blood transfusion within the multicomponent prevention and treatment strategy of delirium. DESIGN: Systematic review. SETTING: We included cohort studies or Randomized Controlled Trials (RCTs) that considered blood transfusion as treatment for delirium or risk factor, and had delirium as outcome. PARTICIPANTS: Hospitalized patients above 55 years old. MEASUREMENTS: We searched MEDLINE from 1946 through November 2014. Quality assessment and data extraction were performed systematically. RESULTS: We included 23 studies (n = 29,471). The majority of the studies (n = 22) had a limited quality and for one study quality was uncertain. Two studies evaluated the association between transfusion strategy and postoperative delirium and found no association. Twenty-one studies investigated blood transfusion as a risk factor for delirium. In four of the 21 studies it could be assumed that delirium occurred after transfusion. One of these studies stated that transfusion was a significant risk factor for subsequent delirium (odds ratio (OR) = 3.68, 95% confidence interval (CI) = 1.32-10.94). The other three studies found no association between transfusion and delirium. In the remaining 17 studies, it was not clear whether delirium occurred before or after transfusion, so no conclusion could be drawn on the role of transfusion in delirium development. CONCLUSION: The majority of the included studies was not suited to answer the research question properly as the time course of the beginning of delirium as to transfusion was lacking. Our review shows that there is no good quality evidence available for blood transfusion to be a risk factor for delirium or to be a preventive or treatment option.

The Effects of Blood Transfusion on Delirium Incidence.

BACKGROUND: Both anemia and blood transfusion could be precipitating factors for delirium; hence in postoperative patients with anemia at high risk for delirium, it is controversial whether transfusion is the best option. The aim of this study is to investigate the association of anemia and delirium and the role of blood transfusion within the multicomponent prevention strategy of delirium. METHODS: We conducted a substudy of a multicenter randomized controlled trial. Four hundred fifteen patients aged 65 to 102 years old admitted for hip fracture surgery were enrolled. Delirium was assessed daily using criteria of the Diagnostic and Statistical Manual of Mental Disorders, fourth edition. Data on hemoglobin values and transfusion were collected from the electronic medical records. RESULTS: One hundred fifteen (32.5%) patients experienced delirium during hospitalization, 238 (57.5%) had a hemoglobin level ≤ 6.0 mmol/L (9.7 g/dL) at any time during hospitalization, and 140 (33.7%) received a blood transfusion. Anemia (a hemoglobin level ≤ 6.0 mmol/L [9.7 g/dL]) was associated with delirium (odds ratio, 1.81; 95% confidence interval, 1.15-2.86). Blood transfusion was a protective factor for delirium in patients with the lowest measured hemoglobin level ≤ 6.0 mmol/L (9.7 g/dL) (odds ratio, 0.26; 95% confidence interval, 0.10-0.70). CONCLUSION: Low hemoglobin level is associated with delirium, and receiving a blood transfusion is associated with a lower delirium incidence. It would be interesting to investigate the effect of blood transfusion as part of the multicomponent treatment of delirium in patients with anemia.
