The management of major orthopedic surgery in the elderly prototypically reflects the perioperative risks of geriatric, often very frail patients reflecting an aging population. To improve outcome, the risks of anesthesia and surgery as well as of patient comorbidities must be thoroughly assessed and balanced using a multidisciplinary approach. Particular risks include cardiopulmonary morbidity, anemia, risk of hemorrhage and the management by anticoagulation, cerebral impairments as well as frailty and limited physiological reserves in general.

Accordingly, an optimized therapy prior to, during, and after surgery will likely influence not only the immediate postoperative course but also hospital mortality and long-term outcome. Publications on the topic of perioperative management of geriatric patients are fortunately gaining in quality and quantity, not least against the background of the demographic developments. Accordingly, specific influencing factors relevant for perioperative management can be increasingly more identified. This short review summarizes the current state of knowledge to provide an overview and rationale for clinical decision making.

Patients treated with anticoagulants may experience serious bleeding or require urgent surgery or intervention, and may benefit from rapid anticoagulant reversal. This exploratory analysis assessed healthcare resource utilization (HCRU) in patients treated with idarucizumab, a specific reversal agent for dabigatran etexilate.
RE-VERSE AD™ (NCT02104947), a prospective, multi-center open-label study, is evaluating idarucizumab for dabigatran reversal in patients with serious bleeding (Group A) or undergoing emergency surgery/procedures (Group B). Read More

HCRU outcome measures evaluated in the first 90 patients enrolled were use of blood products and pro-hemostatic agents, length of stay (LOS) in hospital, and LOS in intensive care unit (ICU).
Blood products or pro-hemostatic agents were given to 63% (32/51) of patients in Group A and 23% (9/39) of patients in Group B on the day of/day after surgery. An overnight hospital stay was reported for 82% (42/51) of patients in Group A with median LOS = 7 (range = 1-71) bed-days. For Group B, 92% (36/39) had an overnight hospital stay with a median LOS = 9 (range = 1-92) bed-days. In Group A, 17 patients were admitted to the ICU for at least 1 day with median LOS = 4 (range = 1-44) days; in Group B the number was 15 with median LOS = 2 (range = 1-92) days.
The lack of a control group and the small patient numbers limit the strength of the conclusions.
The use of idarucizumab may simplify emergency management of dabigatran-treated patients with life-threatening bleeds and reduce perioperative complications in patients undergoing emergency surgery.

Non vitamin-K oral anticoagulants (NOAC) have considerably enhanced anticoagulation practice for non-valvular atrial fibrillation with specific advantages of fixed dosing, non-fluctuant therapeutic levels and obviation of therapeutic level monitoring. NOAC pharmacology is remarkable for considerable renal excretion. Heterogeneity in the precise time cut-offs for discontinuation of NOACs prior to elective surgical or percutaneous procedures arise from the non-linear variations of drug excretion with different levels of creatinine clearances as in chronic kidney disease.

Multiple authors have suggested cut-offs leading to ambiguity among practicing clinicians. Recent data pertaining to systemic thromboembolism, stroke and major bleeding derived from randomized controlled clinical trials have simplified the periprocedural management of NOACs. This review focusses on heterogeneity in the management of NOACs in patients with CKD in this peculiar scenario and highlights the contemporary evidence to support a unified approach towards perioperative management of NOACs. Multiple antidotes targeted towards binding of specific NOACs have been developed and are in the testing phase, thereby offering immense potential for rapid and complete reversal of NOAC activity in emergent procedures and major bleeding episodes. Targeted research on thromboembolism, stroke and major bleeding following temporary periprocedural interruption of NOACs using multicentric registries could further expand the clinical utility of these agents.

It is increasingly common for physicians and anaesthetists to be asked for advice in the medical management of surgical patients who have an incidental history of stroke or transient ischaemic attack (TIA). Advising clinicians requires an understanding of the common predictors, outcomes and management of perioperative stroke. The most important predictor of perioperative stroke is a previous history of stroke, and outcomes associated with such an event are extremely poor. Read More

The perioperative management of this patient group needs careful consideration to minimise the thrombotic risk and a comprehensive, individualised approach is crucial. Although there is literature supporting the management of such patients undergoing cardiac surgery, evidence is lacking in the setting of non-cardiac surgical intervention. This article reviews the current evidence and provides a pragmatic interpretation to inform the perioperative management of patients with a history of stroke and/or TIA presenting for elective non-cardiac surgery.

To assess the current treatment of benign prostatic obstruction (BPO) in patients on ongoing oral anticoagulation (OA).
An Internet survey was sent to all active members of the Endourological Society. The survey contained 32 questions regarding transurethral treatment of BPO in patients on ongoing OA, different techniques, and arising complications. Read More


Out of all members (n = 2000) of the Endourological Society, 133 participated in our survey. Eighty-eight percent of the participants indicated to perform transurethral therapy of BPO on ongoing OA, whereas 60% of this group temporarily pause the OA during the intervention. Sixteen percent perform >30 transurethral interventions of BPO on ongoing OA per year. Most operations are performed under continuation of aspirin (58.2%). The continuation of adenosine diphosphate (ADP)-receptor inhibitors (22.1%), vitamin K antagonists (18.9%), factor Xa inhibitors (15.6%), or the combination of two oral anticoagulants (16.4%) is continued less often. The decision for the operation on ongoing OA is usually approved by the cardiologist (58%) or it cannot be stopped in case of emergency (29%). GreenLight laser (39%) was the most frequently used technique on ongoing OA, followed by monopolar or bipolar transurethral resection of the prostate (35%) as well as other sources of laser [holmium (12%), thulium (12%), diode laser (2%)]. Although OA was continued during the interventions, cardiovascular complications were observed in 31.6%.
Current practice shows that the majority of a representative group of the Endourological Society members perform transurethral therapy of BPO in patients on ongoing OA. The incidence of perioperative complications under transurethral therapy of BPO on ongoing OA is lower than previously assumed.

To compare the relative effects between pharmacological thromboprophylaxis and no anticoagulation.
The efficacy and safety of pharmacological thromboprophylaxis in cancer patients undergoing surgery need to be quantified to guide management.
We searched multiple electronic databases (up to March 31, 2016) for trials of cancer patients undergoing surgery that assessed the relative benefits and harms of perioperative pharmacological thromboprophylaxis. Read More

Relative risks (RRs) with 95% confidence intervals (CI) were estimated.
A total of 39 studies were enrolled in this review. Patients with pharmacological thromboprophylaxis had a relatively reduced incidence of deep venous thrombosis (DVT) compared with those without (0.5% vs 1.2%, RR 0.51, 95% CI 0.27-0.94; P = 0.03) but a significantly increased incidence of bleeding events (RR 2.51, 95% CI 1.79-3.51; P < 0.0001). The incidence of pulmonary embolism (PE) (RR 1.77, 95% CI 0.76-4.14; P = 0.19) and mortality related to venous thromboembolism (VTE) (1/2,811 vs 2/3,380) were similar between the pharmacological thromboprophylaxis group and the no pharmacological thromboprophylaxis group. Low-molecular-weight heparin (LMWH) reduced the incidence of DVT compared with unfractionated heparin (UFH) (RR 0.81, 95% CI 0.66-1.00; P = 0.05), and standard extended thromboprophylaxis after cancer surgery significant decreased the incidence of DVT as compared with conventional thromboprophylaxis (RR 0.57, 95% CI 0.39-0.83; P = 0.003).
Routine pharmacological thromboprophylaxis for cancer patients undergoing surgery needs to be carefully considered, because although thromboprophylaxis is associated with lower VTE events, there is a higher incidence of clinically significant bleeding events. If pharmacological thromboprophylaxis is to be used, extended thromboprophylaxis started preoperatively with LWMH might be the most effective strategy.

Telephone calls play a significant role in the follow-up care of postoperative patients. However, further data is needed to identify the determinants of patient-initiated telephone calls following surgery as these factors may also highlight potential areas of improvement in patient satisfaction and during the hospital discharge process. Thus, the goal of this study is to determine the number of postoperative patient telephone calls within 14 days following surgery and establish the factors associated with patient-initiated calls as well as reasons for calling.

A retrospective chart review of all spine surgeries performed at our institution from January 1, 2014 through January 2, 2015 was completed. Patient demographics, perioperative and operative variables, and telephone encounter data were collected. The primary outcome was a patient-initiated telephone call within 14 days after surgery. Secondary outcomes included reporting and analyzing the reasons for patient phone calls, analyzing which procedures were associated with the most telephone calls, and conducting a multivariate analysis to determine independent risk factors for patient calls.
Of the 488 patients who underwent surgical procedures, 222 patients (45.7%) made a telephone call within 14 days after surgery. 61 patients (27.48%) called regarding pain control. 54 patients (23.87%) called with bathing/dressing/wound questions. Other common categories include: other (21.17%), medication problems (15.77%), weight bearing status/activity restrictions (5.14%), fever (3.15%), bowel management (1.35%), work notes (1.35%), and anticoagulation questions (0.45%). Factors associated with a telephone call within 14 days postoperatively included increased BMI (p=0.031), lower number of comorbidities (p=0.043), telephone call within two weeks prior to surgery (p=0.027), American Society of Anesthesiology (ASA) score of 2 (p=0.036), discharge disposition to home (p=0.003), and elective procedure (p=0.006). Multivariate analysis revealed that fusion procedures (OR: 2.16, 95% CI: 1.05 - 4.45, p = 0.037) and ASA score of 3-4 (OR: 0.55, 95% CI: 0.31 - 0.96, p = 0.036) were independently associated with increased and decreased propensity, respectively, towards making a phone call within two weeks.
Postoperative patient-initiated telephone calls within 14 days following spine surgery are very common, occurring after almost half of all procedures. By evaluating such determinants, patient care can be improved by better addressing patient needs during and prior to discharge to prevent potential unnecessary postoperative calls and improve patient satisfaction.
