Preoperative evaluation and preparation of patients for orthopedic surgery

Delayed elective total shoulder arthroplasty: causes and eventual outcomes

PURPOSE

The purpose of this study is to identify risk factors for delays in planned total shoulder arthroplasty (TSA) and determine the perioperative outcomes of TSAs that experienced a delay.

METHODS

The American College of Surgeons National Quality Improvement Program (NSQIP) database was queried from 2006 to 2019 for primary TSA. Delayed TSA was defined as surgery that occurred greater than one day after hospital admission. Patient demographics, comorbidities, and post-operative complications were collected and compared; the incidence of delayed TSA was analyzed.

RESULTS

The delayed patients were older, had a higher BMI, a higher rate of recent prior major surgery, and more comorbidities. Delayed patients had higher rates of postoperative complications, return to the OR, and 30-day readmission. Between 2006 and 2019, the rate of delayed TSA decreased.

CONCLUSION

Surgeons should take care to ensure that patients with comorbidities undergo thorough preoperative clearance to prevent same-day cancellations and postoperative complications.

Preoperative Optimization and Tips to Avoiding Surgical Complications Before the Incision

In preparation for surgery, it is important for surgeons to have a detailed discussion with patients about the risks, benefits, and alternatives to surgery. Patient optimization, ensuring the patient is in the best medical condition before surgery, is also an important aspect of patient care that the surgeon must consider. Although complications cannot be eliminated, there are often opportunities to optimize patients, so these risks can be minimized based on current evidence-based medicine. To minimize the risk of complications, the surgeon should take an active role in each step of the patient's care beginning with the history and physical examination, obtaining the correct preoperative labs, and continuing through positioning, draping, and prepping before making an incision.

Optimized clinical practice for superaged patients with hip fracture: significance of damage control and enhanced recovery program

With the advent of global aging, the incidence, mortality, and medical costs of hip fracture among aged patients are increasing annually. The number of controlled clinical studies and health economics analyses that conform to evidence-based medicine principles is growing day by day. However, unfortunately, no specific recommendations regarding the procedures for the treatment of hip fracture are available. Meanwhile, the existence of both traditional treatment systems and new treatment theories means that most doctors confront difficult choices in their daily practice. These factors make the therapeutic approach for aged patients, especially among superaged patients with hip fracture, extremely challenging. This study focuses on superaged patients (> 80 years as defined by the World Health Organization) with hip fracture and includes their preoperative pathological condition; therapeutic decision-making in terms of the benefit and risk ratio, damage control theory, and enhanced recovery after surgery were also investigated. These patients were discussed specifically by combining the current treatment strategies from several experts and the results of a meta-analysis published recently. The study presents some new ideas and approaches currently recognized in the field, such as preoperative assessment, surgical planning, safety consideration, complication intervention, and enhanced recovery implementation, and further presents some clear interpretations regarding misunderstandings in clinical practice. Finally, optimized treatment according to damage control principles and enhanced recovery after surgery during the perioperative period among superaged hip fracture patients is defined.

Postoperative Medical Complications and Intermediate Care Unit/Intensive Care Unit Admission in Joint Replacement Surgery: A Prospective Risk Model

BACKGROUND

Postoperative complications are the main consumers of technical, medical, and human resources. Especially in the field of elective joint replacement surgery, a specialized, easy-to-obtain, and cost-efficient preoperative stratification and risk-estimation model is missing.

METHODS

With preoperatively surveyed patient parameters, we identified the most relevant parameters to predict postoperative medical complications. We devised a prospective risk model, measuring the individual probability for intermediate care unit (IMC) or intensive care unit (ICU) admission. The study includes all patients (n = 649) treated with primary or revision total knee arthroplasty in our clinic from 2008 to 2012.

RESULTS

The association between general comorbidity scores and mortality risk is well known. Among different comorbidity scores, the Charlson Comorbidity Index is not only relevant for overall postoperative complications (odds ratios [OR] = 2.20) but also predictive of specific complications such as the postoperative need for blood transfusion (OR = 1.94) and unexpected adverse events (OR = 1.74). Considering adverse events, c-reactive protein and leukocyte levels are also highly relevant. Upon predicting a necessary postoperative transfer to an IMC or ICU, the preoperative hemoglobin level, the Charlson Comorbidity Index, and the Index of Coexistent Disease stood out. The latter indicates an increased rate for an IMC/ICU stay by 341% per point. Condensing the most influential predictors, the probability for postoperative IMC/ICU transfer can be calculated for each individual patient. Using the routinely assessed patient's variables, no steadier prediction is possible.

CONCLUSION

The introduced risk-estimation model offers a specialized preoperative resource-stratification method in knee joint replacement surgery. It condenses the most influential, individual risk factors to avoid clinical test redundancy and improve resource efficiency and presurgical care planning. A prospective follow-up study could help validating the risk model in clinical routine.

Managing Opioid-Tolerant Patients in the Perioperative Surgical Home

Management of acute postoperative pain is important to decrease perioperative morbidity and improve patient satisfaction. Opioids are associated with potential adverse events that may lead to significant risk. Uncontrolled pain is a risk factor in the transformation of acute pain to chronic pain. Balancing these issues can be especially challenging in opioid-tolerant patients undergoing surgery, for whom rapidly escalating opioid doses in an effort to control pain can be associated with increased complications. In the perioperative surgical home model, anesthesiologists are positioned to coordinate a comprehensive perioperative analgesic plan that begins with the preoperative assessment and continues through discharge.
