ReviewChronic pain and substance abuse disorders: Preoperative assessment and optimization strategies.
There is an ever-increasing number of opioid users among chronic pain patients and safely managing them can be challenging for surgeons, anesthesiologists, pain experts, and addiction specialists. Healthcare providers must be familiar with phenomena typical of opioid users and abusers, including tolerance, physical dependence, hyperalgesia, and addiction. ⋯ Preoperative evaluation should identify comorbidities and identify risk factors for substance abuse and withdrawal. Intraoperative and postoperative strategies can ensure safe and effective pain management and minimize the potential for morbidity and mortality in this high-risk patient population.

ReviewPreoperative frailty assessment combined with prehabilitation and nutrition strategies: Emerging concepts and clinical outcomes.
Important elements of the preoperative assessment that should be addressed for the older adult population include frailty, comorbidities, nutritional status, cognition, and medications. Frailty has emerged as a plausible predictor of adverse outcomes after surgery. It is present in older patients and is characterized by multisystem physiologic decline, increased vulnerability to stressors, and adverse clinical outcomes. ⋯ Previous studies have shown an association between increased frailty and the risk of postoperative complications, morbidity, hospital length of stay, and 30-day and long-term mortality following general surgical procedures. Evidence from numerous studies suggests a potential benefit of including a standard assessment of frailty as part of the preoperative workup of older adult patients. Studies addressing validated frailty assessments and the quantification of their predictive capabilities in various surgeries are warranted.

ReviewManaging preoperative anemia: Evolving concepts and strategies for improving patient outcomes.
Anemia is the most common hematological disease, and is defined by the World Health Organization as a condition in which the number of red blood cells and consequently oxygen-carrying capacity is insufficient to meet the physiological needs of the body. Anemia can occur throughout the perioperative period and has important clinical consequences. ⋯ Postoperative anemia is a common event and occurs in 80-90% of patients who have undergone major surgery. This manuscript discusses the detection and management of preoperative anemia, the three pillars of patient blood management, perioperative anemia management, and risk stratification for anemia in the surgical setting.

ReviewTelemedicine for preoperative assessment during a COVID-19 pandemic: Recommendations for clinical care.
Limiting the spread of the disease is key to controlling the COVID-19 pandemic. This includes identifying people who have been exposed to COVID-19, minimizing patient contact, and enforcing strict hygiene measures. ⋯ This new tool can be used to evaluate the severity and progression of the main disease, other comorbidities, and the urgency of the surgical treatment as well as preferencing anesthetic procedures. It can also be used for effective screening and triaging of patients with suspected or established COVID-19, thereby protecting other patients, clinicians and communities alike.

ReviewPreoperative management of anticoagulation in the surgical patient: Highlights of the latest guidelines.
Oral anticoagulants (OACs) are a class of medications commonly used in the long-term management of patients at risk of thrombosis. They include warfarin and direct oral anticoagulants (DOACs). The aging of the population and improvements in perioperative care have led to an increase in the number of patients on OACs and presenting for different types of elective and emergency surgery. ⋯ It is based on the quantification of a patient's individual hemorrhagic and thrombotic risk together with the intrinsic surgical bleeding risk. We reviewed current guidelines to define effective discontinuation of OACs, the need for bridging with different anticoagulants, and post-surgery OACs re-initiation. We also discussed the option for acute reversal of anticoagulation.
