COVID-19 infection and ambulatory surgery: Decision making based on known knowns.

During the spring of 2020, as Coronavirus Disease 2019 (COVID-19) infections rapidly spread across the globe, all sectors of healthcare, everywhere, would change in ways that were unimaginable. Early on, the ambulatory surgery space, being no exception, would suffer deep and impactful reductions in patient volume and revenue. Though actual care stoppages were short-lived, decreased ambulatory surgical patient volumes continued for a myriad of reasons, though in some cases, ambulatory surgery centers (ASCs) provided surgical care in limited numbers to patients who were "offloaded" from inpatient lists. Released on March 24, 2020, herein, we address the key perioperative issues as they relate to COVID-19 and ambulatory surgery including the many complexities and challenges of a new and rapidly changing virus, the impact of viral infection and vaccine development on perioperative outcomes, key ambulatory surgical approaches to COVID-19-related patient and staff safety, and finally, managing issues related to both supply chain (personal protective equipment (PPE) and other necessary equipment) and facility staffing.

Benchmarking outcomes for day surgery.

In comparison to large acute care centers, Ambulatory Surgery Centers (ASCs) provide patient-centered, fast, efficient, effective, high-value, high-quality, reliable, and safe care. For these reasons, ASCs are often preferred working venues for perioperative staff and desirable partners for surgeons, proceduralists, and anesthesiologists. Given today's many headwinds, including inflation, downward rate pressures, increasing regulation, and near constant supply chain issues, not to mention increasing patient and procedural complexity, exemplary clinical and operational management is of paramount importance and requires frequent measurement and benchmarking. Benchmarking is critical to performance assessment and is vital for assessing existing processes and new pathways and protocols, and remains the best way to identify areas for improvement. This chapter provides the reader with an overview of key ASC-related performance indicators, what they mean, and how best to measure and compare them to local, regional, and national benchmarks.

Transport Rates and Prehospital Intervals for an EMS Telemedicine Intervention.

INTRODUCTION: Emergency medical services (EMS) facilitated telemedicine encounters have been proposed as a strategy to reduce transports to hospitals for patients who access the 9-1-1 system. It is unclear which patient impressions are most likely able to be treated in place. It is also unknown if the increased time spent facilitating the telemedicine encounter is offset by the time saved from reducing the need for transport. The objective of this study was to determine the association between the impressions of EMS clinicians of the patients' primary problems and transport avoidance, and to describe the effects of telemedicine encounters on prehospital intervals. METHODS: This was a retrospective review of EMS records from two commercial EMS agencies in New York and Tennessee. For each EMS call where a telemedicine encounter occurred, a matched pair was identified. Clinicians' impressions were mapped to the corresponding category in the International Classification of Primary Care, 2nd edition (ICPC-2). Incidence and rates of transport avoidance for each category were determined. Prehospital interval was calculated as the difference between the time of ambulance dispatch and back-in-service time. RESULTS: Of the 463 prehospital telemedicine evaluations performed from March 2021 to April 2022, 312 (67%) avoided transports to the hospital. Respiratory calls were most likely to result in transport avoidance (p = 0.018); no other categories had statistically significant transport rates. Four hundred sixty-one (99.6%) had matched pairs identified and were included in the analysis. When compared to the matched pair, telemedicine without transport was associated with a prehospital interval reduction in 68% of the cases with a median reduction of 16 min; this is significantly higher than telemedicine with transport when compared to the matched pair with a median interval increase in 27 min. Regardless of transport status, the prehospital interval was a median of 4 min shorter for telemedicine encounters than non-telemedicine encounters (p = 0.08). CONCLUSION: In this study, most telemedicine evaluations resulted in ED transport avoidance, particularly for respiratory issues. Telemedicine interventions were associated with a median four-minute decrease in prehospital interval per call. Future research should investigate the long-term effects of telemedicine on patient outcomes.

Quality of recovery in patients under low- or standard-pressure pneumoperitoneum. A randomised controlled trial.

BACKGROUND: The use of low-pressure pneumoperitoneum seems to be capable of reducing complications such as post-operative pain. However, the quality of evidence supporting this conclusion is low. Both the lack of investigator blinding to both intra-abdominal pressure and to method of neuromuscular blockade represent key sources of bias. Hence, this prospective, randomised, and double-blind study aimed to compare the quality of recovery (Questionnaire QoR-40) of patients undergoing laparoscopic cholecystectomy under low-pressure and standard-pressure pneumoperitoneum. We tested the hypothesis that low pneumoperitoneum pressure enhances the quality of recovery following LC. METHODS: Eighty patients who underwent elective laparoscopic cholecystectomy were randomly divided into two groups, a low-pressure (10 mm Hg) pneumoperitoneum group and a standard-pressure (14 mm Hg) pneumoperitoneum group. For all participants, the value of the insufflation pressure was kept hidden and only the nurse responsible for the operating room was aware of it. Deep neuromuscular blockade was induced for all cases [train-of-four (TOF) = 0; post-tetanic count (PTC) > 0]. The quality of recovery was assessed on the morning of first post-operative day. RESULTS: No difference was found in either total score or in its different dimensions according to the QoR-40 questionnaire. The patients in the low-pressure pneumoperitoneum group experienced more pain during forced coughing measured at 4 hours (median difference [95% CI], 1 [0-2]; P = .030), 8 hours (1 [0-2]; P = .030) and 12 hours (0 [0-1] P = .025) after discharge from the post-anaesthesia care unit, when compared with those in the standard-pressure pneumoperitoneum group. CONCLUSION: We thus conclude that the use of low-pressure pneumoperitoneum during elective laparoscopic cholecystectomy does not improve the quality of recovery.

Intraoperative Cardiac Arrest.

Cardiac arrest in the operating room and in the immediate postoperative period is a potentially catastrophic event that is almost always witnessed and is frequently anticipated. Perioperative crises and perioperative cardiac arrest, although often catastrophic, are frequently managed in a timely and directed manner because practitioners have a deep knowledge of the patient's medical condition and details of recent procedures. It is hoped that the approaches described here, along with approaches for the rapid identification and management of specific high-stakes clinical scenarios, will help anesthesiologists continue to improve patient outcomes.

Documentation of individualized preoperative risk assessment: a multi-center study.

BACKGROUND: Individual surgical risk assessment (ISRA) enhances patient care experience and outcomes by informing shared decision-making, strengthening the consent process, and supporting clinical management. Neither the use of individual pre-surgical risk assessment tools nor the rate of individual risk assessment documentation is known. The primary endpoint of this study was to determine the rate of physician documented ISRAs, with or without a named ISRA tool, within the records of patients with poor outcomes. Secondary endpoints of this work included the effects of age, sex, race, ASA class, and time and type of surgery on the rate of documented presurgical risk. METHODS: The records of non-obstetric surgical patients within 22 community-based private hospitals in Arizona, Colorado, Nebraska, Nevada, and Wyoming, between January 1 and December 31, 2017, were evaluated. A two-sample proportion test was used to identify the difference between surgical documentation and anesthesiology documentation of risk. Logistic regression was used to analyze both individual and group effects associated with secondary endpoints. RESULTS: Seven hundred fifty-six of 140,756 inpatient charts met inclusion criteria (0.54%, 95% CI 0.50 to 0.58%). ISRAs were documented by 16.08% of surgeons and 4.76% of anesthesiologists (p < 0.0001, 95% CI -0.002 to 0.228). Cardiac surgeons documented ISRAs more frequently than non-cardiac surgeons (25.87% vs 16.15%) [p = 0.0086, R-squared = 0.970%]. Elective surgical patients were more likely than emergency surgical patients (19.57 vs 12.03%) to have risk documented (p = 0.023, R-squared = 0.730%). Patients over the age of 65 were more likely than patients under the age of 65 to have ISRA documentation (20.31 vs 14.61%) [p = 0.043, R-squared = 0.580%]. Only 10 of 756 (1.3%) records included documentation of a named ISRA tool. CONCLUSIONS: The observed rate of documented ISRA in our sample was extremely low. Surgeons were more likely than anesthesiologists to document ISRA. As these individualized risk assessment discussions form the bedrock of perioperative informed consent, the rate and quality of risk documentation must be improved.

The Quality of Recovery after Dexamethasone, Ondansetron, or Placebo Administration in Patients Undergoing Lower Limbs Orthopedic Surgery under Spinal Anesthesia Using Intrathecal Morphine. A Randomized Controlled Trial.

Intrathecal morphine is widely and successfully used to prevent postoperative pain after orthopedic surgery, but it is frequently associated with side effects. The aim of this study was to evaluate the effect of dexamethasone or ondansetron when compared to placebo to reduce the occurrence of these undesirable effects and, consequently, to improve the quality of recovery based on patient's perspective. Methods. One hundred and thirty-five patients undergoing lower extremity orthopedic surgery under spinal anesthesia using bupivacaine and morphine were randomly assigned to receive IV dexamethasone, ondansetron, or saline. On the morning following surgery, a quality of recovery questionnaire (QoR-40) was completed. Results. No differences were detected in the global and dimensional QoR-40 scores following surgery; however, following postanesthesia care unit (PACU) discharge, pain scores were higher in patients receiving ondansetron compared with patients who received dexamethasone. Conclusion. Neither ondansetron nor dexamethasone improves the quality of recovery after lower limbs orthopedic surgery under spinal anesthesia using intrathecal morphine.

Outcomes in Ambulatory Anesthesia: Measuring What Matters.

Health care professionals see measurement through their own eyes and biases. This article makes the patient central to what is measured. Patient-reported experience measures and patient-reported outcome measures are of the utmost importance. In addition, as clinicians continue to evolve how they measure what really matters, they need to be mindful of the time taken from direct patient care to achieve these activities. In addition, and most important, clinicians must ensure that all measures are designed to ensure that population health is improved, that patient experience and outcomes are enhanced, and that the cost of care is reduced.

Perioperative Quality Initiative consensus statement on intraoperative blood pressure, risk and outcomes for elective surgery.

BACKGROUND: Intraoperative mortality is now rare, but death within 30 days of surgery remains surprisingly common. Perioperative myocardial infarction is associated with a remarkably high mortality. There are strong associations between hypotension and myocardial injury, myocardial infarction, renal injury, and death. Perioperative arterial blood pressure management was thus the basis of a Perioperative Quality Initiative consensus-building conference held in London in July 2017. METHODS: The meeting featured a modified Delphi process in which groups addressed various aspects of perioperative arterial pressure. RESULTS: Three consensus statements on intraoperative blood pressure were established. 1) Intraoperative mean arterial pressures below 60-70 mm Hg are associated with myocardial injury, acute kidney injury, and death. Injury is a function of hypotension severity and duration. 2) For adult non-cardiac surgical patients, there is insufficient evidence to recommend a general upper limit of arterial pressure at which therapy should be initiated, although pressures above 160 mm Hg have been associated with myocardial injury and infarction. 3) During cardiac surgery, intraoperative systolic arterial pressure above 140 mm Hg is associated with increased 30 day mortality. Injury is a function of arterial pressure severity and duration. CONCLUSIONS: There is increasing evidence that even brief durations of systolic arterial pressure <100 mm Hg and mean arterial pressure <60-70 mm Hg are harmful during non-cardiac surgery.

The effect of methadone on postoperative quality of recovery in patients undergoing laparoscopic cholecystectomy: A prospective, randomized, double blinded, controlled clinical trial.

STUDY OBJECTIVES: The aim of the present study was to assess the quality of recovery from anesthesia in patients undergoing laparoscopic cholecystectomy (LC) under total intravenous anesthesia, who received either methadone or morphine for post-surgical analgesia by means of questionnaire Quality of Recovery-40 (QoR-40). DESIGN: Prospective Randomized Clinical Trial. SETTING: The setting was at an operating room, postoperative recovery area and hospital ward. PATIENTS: Seventy patients who underwent LC under remifentanil-based anesthesia were randomly assigned to receive methadone 0.1 mg kg-1 or morphine 0.1 mg kg-1. MEASUREMENTS: The primary outcome was the quality of recovery, using the Quality of Recovery Questionnaire (QoR-40). Secondary outcomes included time to eye opening, the occurrence of nausea and vomiting, pain score, use of supplemental analgesics, and PACU length of stay. MAIN RESULTS: No differences were observed in the total or individual QoR-40 dimension scores. During the PACU stay, the occurrence of PONV and pain scores were similar between groups. Opioid consumption (p < 0.02) and the level of sedation (p < 0.01) were higher in the morphine group. There were no differences in the amount of time required to achieve PACU discharge criteria. The frequency of nausea or emesis, the severity of pain, and tramadol consumption were comparable between both groups while on the ward. CONCLUSIONS: Pain scores and the Quality of Recovery did not differ between patients who underwent LC under total intravenous anesthesia, who received either methadone or morphine for post-surgical analgesia.

A System-Wide Enhanced Recovery Program Focusing on Two Key Process Steps Reduces Complications and Readmissions in Patients Undergoing Bowel Surgery.

Enhanced recovery programs (ERPs) can improve outcomes following bowel surgery, but implementing an ERP across a large healthcare system remains challenging. In this study, a simplified ERP that focused on two process steps, early and frequent ambulation and early alimentation, was evaluated to determine its impact on outcomes. Data were collected on 5,000 adult patients undergoing elective small and large bowel operations over a 3-year period. Complication, readmission, and mortality rates were evaluated before and after ERP implementation. A composite score was calculated based on the successful completion of the two process steps. Following implementation, there was a 35.1% increase in the composite score, which was associated with significant (p < .05) reductions in overall complications, gastrointestinal complications, pulmonary complications, and readmissions. A system-wide ERP focusing on early and frequent ambulation and early alimentation is associated with decreased complications and readmissions in adult patients admitted for elective small or large bowel operations.
