Technology-Based Music Interventions to Reduce Anxiety and Pain Among Patients Undergoing Surgery or Procedures: Systematic Review of the Literature.

BACKGROUND: Hospitalized patients undergoing surgery or procedures may experience negative symptoms. Music is a nonpharmacological complementary approach and is used as an intervention to reduce anxiety, stress, and pain in these patients. Recently, music has been used conveniently in clinical situations with technology devices, and the mode of providing music is an important factor in technology-based music interventions. However, many reviews have focused only on the effectiveness of music interventions. OBJECTIVE: We aimed to review randomized controlled trials (RCTs) of technology-based music interventions for reducing anxiety and pain among patients undergoing surgery or procedures. We examined the clinical situation, devices used, delivery methods, and effectiveness of technology-based music interventions in primary articles. METHODS: The search was performed in the following 5 electronic databases: PubMed, MEDLINE (OvidSP), CINAHL complete, PSYCINFO, and Embase. This systematic review focused on technology-based music interventions. The following articles were included: (1) RCTs, (2) studies using interactive technology (eg, smartphones, mHealth, tablets, applications, and virtual reality), (3) empirical studies reporting pain and anxiety outcomes, and (4) English articles published from 2018 to 2023 (as of January 18, 2023). The risk of bias was assessed using the Cochrane Risk of Bias tool version 2. RESULTS: Among 292 studies identified, 21 met the inclusion criteria and were included. Of these studies, 9 reported that anxiety scores decreased after music interventions and 7 reported that pain could be decreased before, during, and after procedures. The methodology of the music intervention was important to the results on anxiety and pain in the clinical trials. More than 50% (13/21, 62%) of the studies included in this review allowed participants to select themes themselves. However, it was difficult to distinguish differences in effects depending on the device or software used for the music interventions. CONCLUSIONS: Technology-based music interventions could help reduce anxiety and pain among patients undergoing surgery or procedures. The findings of this review could help medical teams to choose a practical methodology for music interventions. Future studies should examine the effects of advanced technology-based music interventions using smart devices and software that promote interactions between medical staff and patients.

Construction and validation of a scenario for sedation training in the emergency room for pediatric surgical procedures by in-situ simulation.

INTRODUCTION: sedation and analgesia are fundamental procedures for children undergoing invasive interventions, and complications must be avoided during their implementation. In situ simulation allows, in turn, training in real practice environments to improve the technical and non-technical skills of professionals for such procedures. Although it is a very useful tool, it is often not used due to lack of preparation for its planning and application. OBJECTIVE: develop and validate an in situ simulation scenario in pediatric emergency care using sedation to perform an invasive procedure. METHOD: descriptive study of construction and content validation of an in situ simulation scenario, using the Delphi method, following the following steps: 1) definition of the problem and selection of experts; 2) development of the initial document; 3) rounds for validation with analysis of responses and feedback (until consensus is reached by the Content Validation Index); 4) final report. Results: The experts indicated suggestions that were duly used and the scenario obtained, in all items, a CVI greater than 80.0%, demonstrating its high validity and reliability. By using experts to validate the scenario, their insights guarantee greater precision and reliability in scenario construction engineering. CONCLUSION: It is expected that this study will allow the replication of the scenario in different training contexts, facilitating and encouraging professional training based on a scenario model based on best evidence and practices.

Exploring variation in length of hospital stay among an elderly cohort of acute surgical admissions.

Aim Increased length of stay (LOS) indicates complex health care needs. It is unclear if age alone can be used as an indicator of longer hospital stays. Methods Retrospective review of acute surgical admissions (2016-2018) was performed, dividing data into three age groups (Group 1 (ages 65­74), Group 2 (ages 75­84) and Group 3 ( aged 85 and above). Effect of the independent variables; age, Groups of Episodes with similar diagnosis (GESD) and surgical interventions was noted on the LOS as well as discharge disposition and mortality. Subset analysis was performed for admissions with above average LOS. Results 1880 (27.7%) patients (total admissions=6793) were analysed. Mean LOS in each age group was 12.5, 13.3 and 12.5 days respectively (p=0.68). There was a mean 13 day increase with acute surgical intervention under General Anaesthesia, in comparison to 7.3 days and 5 days for Interventional Radiology and emergency endoscopy. 1496 (79.6%) patients were discharged home. 118 (66.0%) patients transferred to convalescent centres were over 75 years. Among those with above average LOS no significant correlation was found between sex, diagnosis, interventions with longer LOS. Discussion In acute settings, variables other than age are important to understand the variation in LOS. LOS is significantly influenced by diagnosis and acute intervention. Once patients exceed average LOS, resources should be explored to facilitate discharge planning.

Comparing resident operative volumes for routine general surgery cases at academic, urban community, and rural training sites.

BACKGROUND: Surgical training traditionally took place at academic centres, but changed to incorporate community and rural hospitals. As little data exist comparing resident case volumes between these locations, the objective of this study was to determine variations in these volumes for routine general surgery procedures. METHODS: We analyzed senior resident case logs from 2009 to 2019 from a general surgery residency program. We classified training centres as academic, community, and rural. Cases included appendectomy, cholecystectomy, hernia repair, bowel resection, adhesiolysis, and stoma formation or reversal. We matched procedures to blocks based on date of case and compared groups using a Poisson mixed-methods model and 95% confidence intervals (CIs). RESULTS: We included 85 residents and 28 532 cases. Postgraduate year (PGY) 3 residents at academic sites performed 10.9 (95% CI 10.1-11.6) cases per block, which was fewer than 14.7 (95% CI 13.6-15.9) at community and 15.3 (95% CI 14.2-16.5) at rural sites. Fourth-year residents (PGY4) showed a greater difference, with academic residents performing 8.7 (95% CI 8.0-9.3) cases per block compared with 23.7 (95% CI 22.1-25.4) in the community and 25.6 (95% CI 23.6-27.9) at rural sites. This difference continued in PGY5, with academic residents performing 8.3 (95% CI 7.3-9.3) cases per block, compared with 18.9 (95% CI 16.8-21.0) in the community and 14.5 (95% CI 7.0-21.9) at rural sites. CONCLUSION: Senior residents performed fewer routine cases at academic sites than in community and rural centres. Programs can use these data to optimize scheduling for struggling residents who require exposure to routine cases, and help residents complete the requirements of a Competence by Design curriculum.

High body mass index is associated with elevated risk of perioperative ischemic stroke in patients who underwent noncardiac surgery: A retrospective cohort study.

BACKGROUND: Body mass index (BMI) serves as a global metric for assessing obesity and overall health status. However, the impact of BMI, treated as a continuous variable, on the risk of perioperative stroke remains poorly understood. This retrospective cohort study aimed to elucidate the association between BMI and the risk of perioperative ischemic stroke in patients undergoing non-cardiovascular surgery. METHODS: A cohort of 223,415 patients undergoing noncardiac surgery at the First Medical Center of Chinese PLA General Hospital between January 1, 2008 and August 31, 2019 was screened. Preoperative high BMI, defined as BMI >22.64 kg/m2, was the primary exposure, and the outcome of interest was the new diagnosis of perioperative ischemic stroke within 30 days post-surgery. Robust controls for patient and intraoperative factors were implemented to minimize residual confounding. Logistic regression and propensity score matching were employed, and patients were stratified into subgroups for further investigation. RESULTS: The overall incidence of perioperative ischemic stroke was 0.23% (n = 525) in the cohort. After adjusting for patient-related variables (OR 1.283; 95% CI, 1.04-1.594; p < 0.05), surgery-related variables (OR 1.484; 95% CI, 1.2-1.849; p < 0.001), and all confounding variables (OR 1.279; 95% CI, 1.025-1.607; p < 0.05), patients with BMI >22.64 kg/m2 exhibited a significantly increased risk of perioperative ischemic stroke. This association persisted in the propensity score matched cohort (OR 1.577; 95% CI, 1.203-2.073; p < 0.01). Subgroup analyses indicated that preoperative BMI >22.64 kg/m2 correlated with an elevated risk of perioperative ischemic stroke in female patients, those with coronary heart disease, peripheral vascular diseases, and individuals undergoing neurosurgery. CONCLUSION: We first identified BMI >22.64 kg/m2 as a substantial and independent risk factor for perioperative ischemic stroke in Chinese noncardiac surgery patients. Normal BMI may not suffice as a universal preventive standard. Instead, a more stringent perioperative weight management approach is recommended, particularly for specific subgroups such as female patients, those with coronary heart disease and peripheral vascular disease, and individuals scheduled for neurosurgery.

Incidence and risk factors of new persistent opioid use after surgery and trauma: A systematic review.

BACKGROUND: Persistent opioid use (POU) can occur with opioid use after surgery or trauma. Current systematic reviews include patients with previous exposure to opioids, meaning their findings may not be relevant to patients who are opioid naïve (i.e. Most recent exposure was from surgery or trauma). The aim of this review was to synthesise narratively the evidence relating to the incidence of, and risk factors for POU in opioid-naïve surgical or trauma patients. METHOD: Structured searches of Embase, Medline, CINAHL, Web of Science, and Scopus were conducted, with final search performed on the 17th of July 2023. Searches were limited to human participants to identify studies that assessed POU following hospital admission due to surgery or trauma. Search terms relating to 'opioid', 'analgesics', 'surgery', 'injury', 'trauma' and 'opioid-related disorder' were combined. The Newcastle-Ottawa Scale for cohort studies was used to assess the risk of bias for studies. RESULTS: In total, 22 studies (20 surgical and two trauma) were included in the analysis. Of these, 20 studies were conducted in the United States (US). The incidence of POU for surgical patients 18 and over ranged between 3.9% to 14.0%, and for those under 18, the incidence was 2.0%. In trauma studies, the incidence was 8.1% to 10.5% among patients 18 and over. Significant risk factors identified across surgical and trauma studies in opioid-naïve patients were: higher comorbidity burden, having pre-existing mental health or chronic pain disorders, increased length of hospital stay during the surgery/trauma event, or increased doses of opioid exposure after the surgical or trauma event. Significant heterogeneity of study design precluded meta-analysis. CONCLUSION: The quality of the studies was generally of good quality; however, most studies were of US origin and used medico-administrative data. Several risk factors for POU were consistently and independently associated with increased odds of POU, primarily for surgical patients. Awareness of these risk factors may help prescribers recognise the risk of POU after surgery or trauma, when considering continuing opioids after hospitalisation. The review found gaps in the literature on trauma patients, which represents an opportunity for future research. TRIAL REGISTRATION: PROSPERO registration: CRD42023397186.

Unmet Surgical Need among Adults in A Mixed Urban-Rural Community in Nigeria: A Survey of 1,993 Adults Using the Sosas Survey Tool.

INTRODUCTION: Community-based prevalence studies are known to be more accurate than hospital-based records. However, such community-based prevalence studies are uncommon in low- and middle-income countries including Nigeria. Allocation of resources and prioritization of health care needs by policy makers require data from such community-based studies to be meaningful and sustainable. This study aims to assess the prevalence of common surgical conditions amongst adults in Nigeria. METHODS: A descriptive cross-sectional community-based study to determine the prevalence of congenital and acquired surgical conditions in adults in a mixed rural-urban area of Lagos was conducted. The study population comprised resident members in the Ikorodu Local Government Area (LGA) of Lagos State. Data was collected using a modified version of the interviewer-administered questionnaire, the Surgeons OverSeas Assessment of Surgical Need (SOSAS) survey tool. Data was analysed using the REDCap analytic tool. RESULTS: Eight hundred and fifty-six households were surveyed with a yield of 1,992 adults. There were 95 adults who complained of surgical conditions giving a prevalence rate of 5%. Vast majority of reported conditions were acquired deformities (n=94) while only 1 congenital deformity was reported. Others included breast lumps, anterior neck swelling, and groin swellings. CONCLUSION: The most common surgical complaints in our setting among adults were acquired conditions of the extremities and open wounds/sores. With an estimated population of 90 million adults and approximately 1,200 orthopaedic and general surgeons respectively, the surgeon-to-affected population ratio is 1:10,000. There is a large gap to be filled in terms of surgical manpower development.

INTRODUCTION: Les études de prévalence communautaires sont connues pour être plus précises que les dossiers hospitaliers. Cependant, de telles études de prévalence communautaires sont rares dans les pays à revenu faible et intermédiaire, y compris le Nigeria. L'allocation des ressources et la priorisation des besoins de santé par les décideurs nécessitent des données issues de telles études communautaires pour être significatives et durables. Cette étude vise à évaluer la prévalence des affections chirurgicales courantes chez les adultes au Nigeria. MÉTHODES: Une étude descriptive transversale basée sur la communauté pour déterminer la prévalence des conditions chirurgicales congénitales et acquises chez les adultes dans une zone rurale-urbaine mixte de Lagos a été menée. La population étudiée comprenait des membres résidents de la zone de gouvernement local (LGA) d'Ikorodu, dans l'État de Lagos. Les données ont été collectées à l'aide d'une version modifiée du questionnaire administré par un enquêteur, l'outil d'enquête Surgeons OverSeas Assessment of Surgical Need (SOSAS). Les données ont été analysées à l'aide de l'outil analytique REDCap. RÉSULTATS: Huit cent cinquante-six ménages ont été enquêtés, ce qui a donné 1 992 adultes. Quatre-vingt-quinze adultes se sont plaints de conditions chirurgicales, donnant un taux de prévalence de 5 %. La grande majorité des conditions rapportées étaient des déformations acquises (n=94) tandis qu'une seule déformation congénitale a été signalée. Les autres incluaient des nodules mammaires, des gonflements antérieurs du cou et des gonflements inguinaux. CONCLUSION: Les plaintes chirurgicales les plus courantes dans notre cadre parmi les adultes étaient des conditions acquises des extrémités et des plaies ouvertes/ulcères. Avec une population estimée à 90 millions d'adultes et environ 1 200 chirurgiens orthopédiques et généralistes respectivement, le ratio chirurgien-population affectée est de 1:10,000. Il y a un grand écart à combler en termes de développement de la main-d'œuvre chirurgicale. MOTS CLÉS: Prévalence, Charge de morbidité, Chirurgie, Plaies.

Timing of Intraoperative Transitions of Care Among Anesthesiologists Is Not Associated With Postoperative Adverse Outcomes: Retrospective Cohort Study.

BACKGROUND: The majority of published research suggests that anesthesia handovers during major surgical procedures are associated with unintended harmful consequences. It is still unclear if the number or quality of the transition of care is the main driver of the adverse outcomes. There is even less data if the timing of the anesthesiologist handovers during the critical portion of the anesthetic continuum (induction or emergence versus surgical period) plays a role in patient outcomes. Therefore, we investigated if the anesthesiologist handovers during induction and emergence are associated with adverse patient outcomes. METHODS: This retrospective investigation included noncardiac surgical procedures occurring between January 1, 2012 and December 31, 2019 that had exactly 1 attending anesthesiologist handover. We categorized transitions of care between attending anesthesiologists as being before incision, between incision and closing, and after closing. Our primary outcome was a composite of 6 categories of surgical complications and in-hospital mortality. We created logistic generalized estimating equation models to estimate the average relative effect odds ratio between each pair of the 3 transition timing groups across the components of the composite outcome. Inverse probability of treatment weights were used to mitigate confounding on a host of baseline variables. We used Bonferroni correction to adjust for multiple comparisons between the transition groups. RESULTS: In total, we studied 36,937 procedures with exactly 1 attending anesthesiologist handover. Of these records, 4370 had the transition during induction, 24,999 between incision and closure, and 7568 during emergence. No differences were found between the transition periods and the composite outcome. The estimated average relative effect odds ratio (98.3% confidence interval [CI]) across the components of the composite outcome was as follows: (1.0002 [0.81-1.24], P = .99) between the induction and surgical period; (1.10 [0.87-1.40], P = .32) between the induction and emergence periods; and (0.91 [0.79-1.04], P = .08) between the emergence and surgical periods. CONCLUSIONS: Timing of intraoperative handover among attending anesthesiologists during noncardiac surgery is not associated with adverse patient outcomes.

[SPOR covers 100 percent of publicly run surgical care]. / SPOR ­ täckande data om över 5 miljoner ingrepp.

The Swedish Perioperative Register (SPOR) - a national quality register - supports automatic data transfer from local medical records to its central database, without the need for further manual input. Covering 100 percent of surgical operations across all publicly run hospitals in Sweden, SPOR data show regional inequality regarding patients' waiting time from the decision to operate until the start of surgery. SPOR data can inform several areas of improvement for perioperative care, such as management of postoperative pain and nausea, increased use of the Checklist for Safe Surgery, and improved logistics. The growing number of online reports downloaded locally suggests increasing use of SPOR data for follow-up and care improvement efforts. Data from many privately run surgical units do not appear in the SPOR due to technical difficulties in reporting.

Looking Beyond the Numbers: A Comparison of Operative Self-Efficacy, Supervision, and Case Volume in General Surgery Residency.

Background A national survey of general surgery residents revealed significant self-assessed deficits in preparation for independent practice, with only 7.7% of graduating postgraduate year 5 residents (n=1145) reporting self-efficacy for all 10 commonly performed operations surveyed. Objective We sought to understand why this phenomenon occurs. We hypothesized that self-efficacy would be positively correlated with both operative independence and case volume. Methods We compared 3 independent datasets: case information for the same 10 previously surveyed operations for residents graduating in 2020 (dataset 1), operative independence data obtained through the SIMPL OR app, an operative self-assessment tool (dataset 2), and case volume data obtained through the Accreditation Council for Graduate Medical Education National Data Report (dataset 3). Operations were categorized into high, middle (mid), and low self-efficacy tiers; analysis of variance was used to compare operative independence and case volume per tier. Results There were significant differences in self-efficacy between high (87.7%), mid (68.3%), and low (25.4%) tiers (P=.008 [95% CI 6.2, 32.7] for high vs mid, P<.001 for high vs low [49.1, 75.6], and P<.001 for mid vs low [28.7, 57.1]). The percentage of cases completed with operative independence followed similar trends (high 32.7%, mid 13.8%, low 4.9%, P=.006 [6.4, 31.4] for high vs mid, P<.001 [15.3, 40.3] for high vs low, P=.23 [-4.5, 22.3] for mid vs low). The total volume of cases decreased from high to mid to low self-efficacy tiers (average 91.8 to 20.8 to 11.1) but did not reach statistical significance on post-hoc analysis. Conclusions In this analysis of US surgical residents, operative independence was strongly correlated with self-efficacy.

Randomized Pilot Trial of Pre- and Postoperative Heart Failure Nurse-Supported Care in Heart Failure Patients Requiring Noncardiac Surgery-Feasibility and Results.

INTRODUCTION: The perioperative cardiovascular management of patients undergoing noncardiac surgery is particularly challenging in those with pre-existing heart failure (HF). This study was designed to evaluate the effectiveness of nurse-based pre- and postoperative specialized HF management in reducing postoperative HF-associated complications in patients with known HF undergoing noncardiac surgery. METHODS: This prospective, randomized pilot study included patients with established HF requiring intermediate- to high-risk noncardiac surgery. Patients received postoperatively either standard care (control group, CG) or nurse-supported HF management (intervention group, IG). The primary endpoint was a composite of HF-related postoperative complications at 30 days. Secondary endpoints included length on intensive care unit, length of hospital stay, death, hospitalization for HF, and quality of life assessment using the SF-12 questionnaire. RESULTS: The trial was halted prematurely for futility. A total of 34 patients (median age 70.5 [IQR 67-75] years; with 15 HfpEF, 9 HfmrEF,10 HfrEF), with an average NT-proBNP of 1.413 [463-2.832] pg/mL were included. The IG had a lower rate of postoperative primary events (25%; n = 4) compared with the CG (33%; n = 6). There were no differences in secondary endpoints between the groups. Quality-of-life scores improved slightly in both groups (δ 5.6 ± 0.9 [CG] and 3.1 ± 1.2 [IG]). CONCLUSION: Nurse-based pre- and postoperative HF care appears to be feasible and may reduce HF-associated complications in patients undergoing noncardiac surgery. Larger clinical trials are needed to further evaluate the effectiveness of this approach in reducing postoperative complications in this high-risk patient population.

How ready is the health care system in Northeast India for surgical delivery? a mixed-methods study on surgical capacity and need.

BACKGROUND: Surgical services are scarce with persisting inequalities in access across populations and regions globally. As the world's most populous county, India's surgical need is high and delivery rates estimated to be sub-par to meet need. There is a dearth of evidence, particularly sub-regional data, on surgical provisioning which is needed to aid planning. AIM AND METHOD: This mixed-methods study examines the state of surgical care in Northeast India, specifically health care system capacity and barriers to surgical delivery. It involved a facility-based census and semi-structured interviews with surgeons and patients across four states in the region. RESULTS: Abdominal conditions constituted a large portion of the overall surgeries across public and private facilities in the region. Workloads varied among surgical providers across facilities. Task-shifting occurred, involving non-specialist nursing staff assisting doctors with surgical procedures or surgeons taking on anaesthetic tasks. Structural factors dis-incentivised facility-level investment in suitable infrastructure. Facility functionality was on average higher in private providers compared to public providers and private facilities offer a wider range of surgical procedures. Facilities in general had adequate laboratory testing capability, infrastructure and equipment. Public facilities often do not have surgeon available around the clock while both public and private facilities frequently lack adequate blood banking. Patients' care pathways were shaped by facility-level shortages as well as personal preferences influenced by cost and distance to facilities. DISCUSSION AND CONCLUSION: Skewed workloads across facilities and regions indicate uneven surgical delivery, with potentially variable care quality and provider efficiency. The need for a more system-wide and inter-linked approach to referral coordination and human resource management is evident in the results. Existing task-shifting practices, along with incapacities induced by structural factors, signal the directions for possible policy action.

Identifying opportunities for global surgery in Cameroon: an analysis of existing health policies and events.

Introduction: the burden of diseases amenable to surgery, obstetrics, trauma, and anesthesia (SOTA) care is increasing globally but low- and middle-income countries are disproportionately affected. The Lancet Commission on Global Surgery proposed National Surgical, Obstetrics, and Anesthesia Plans as national policies to reduce the global SOTA burden. These plans are dependent on comprehensive stakeholder engagement and health policy analysis. Objective: in this study, we analyzed existing national health policies and events in Cameroon to identify opportunities for SOTA policies. Methods: we searched the Cameroonian Ministry of Health´s health policy database to identify past and current policies. Next, the policies were retrieved and screened for mentions of SOTA-related interventions using relevant keywords in French and English, and analyzed using the 'eight-fold path´ framework for public policy analysis. Results: we identified 136 policies and events and excluded 16 duplicates. The health policies and events included were implemented between 1967 and 2021. Fifty-nine policies and events (49.2%) mentioned SOTA care: governance (n=25), infrastructure (n=21), service delivery (n=11), workforce (n=11), information management (n=10), and funding (n=8). Most policies and events focused on maternal and neonatal health, followed by anesthesia, ophthalmologic surgery, and trauma. National, multinational civil society organizations and private stakeholders supported these policies and events, and the Cameroonian Ministry of Public Health was the largest funder. Conclusion: most Cameroonian SOTA-related policies and events focus on maternal and neonatal care, and health financing is the health system component with the least policies and events. Future SOTA policies should build on existing strengths while improving neglected areas, thus attaining shared global and national goals by 2030.

Pediatric Surgical Opioid Prescribing by Procedure, 2020-2021.

BACKGROUND AND OBJECTIVES: Surgery is one of the most common indications for opioid prescribing to pediatric patients. We identified which procedures account for the most pediatric surgical opioid prescribing. METHODS: We conducted a cross-sectional analysis of commercial and Medicaid claims in the Merative MarketScan Commercial and Multi-State Medicaid Databases. Analyses included surgical procedures for patients aged 0 to 21 years from December 1, 2020, to November 30, 2021. Procedures were identified using a novel crosswalk between 3664 procedure codes and 1082 procedure types. For each procedure type in the crosswalk, we calculated the total amount of opioids in prescriptions dispensed within 3 days of discharge from surgery, as measured in morphine milligram equivalents (MMEs). We then calculated the share of all MMEs accounted for by each procedure type. We conducted analyses separately among patients aged 0 to 11 and 12 to 21 years. RESULTS: Among 107 597 procedures for patients aged 0 to 11 years, the top 3 procedures accounted for 59.1% of MMEs in opioid prescriptions dispensed after surgery: Tonsillectomy and/or adenoidectomy (50.3%), open treatment of upper extremity fracture (5.3%), and removal of deep implants (3.5%). Among 111 406 procedures for patients aged 12 to 21 years, the top 3 procedures accounted for 33.1% of MMEs: Tonsillectomy and/or adenoidectomy (12.7%), knee arthroscopy (12.6%), and cesarean delivery (7.8%). CONCLUSIONS: Pediatric surgical opioid prescribing is concentrated among a small number of procedures. Targeting these procedures in opioid stewardship initiatives could help minimize the risks of opioid prescribing while maintaining effective postoperative pain control.

Epidemiology of Opioid Prescribing After Discharge From Surgical Procedures Among Adults.

Importance: Opioid medications are commonly prescribed for the management of acute postoperative pain. In light of increasing awareness of the potential risks of opioid prescribing, data are needed to define the procedures and populations for which most opioid prescribing occurs. Objective: To identify the surgical procedures accounting for the highest proportion of opioids dispensed to adults after surgery in the United States. Design, Setting, and Participants: This cross-sectional analysis of the 2020-2021 Merative MarketScan Commercial and Multi-State Databases, which capture medical and pharmacy claims for 23 million and 14 million annual privately insured patients and Medicaid beneficiaries, respectively, included surgical procedures for individuals aged 18 to 64 years with a discharge date between December 1, 2020, and November 30, 2021. Procedures were identified using a novel crosswalk between 3664 Current Procedural Terminology codes and 1082 procedure types. Data analysis was conducted from November to December 2023. Main Outcomes and Measures: The total amount of opioids dispensed within 3 days of discharge from surgery across all procedures in the sample, as measured in morphine milligram equivalents (MMEs), was calculated. The primary outcome was the proportion of total MMEs attributable to each procedure type, calculated separately among procedures for individuals aged 18 to 44 years and those aged 45 to 64 years. Results: Among 1 040 934 surgical procedures performed (mean [SD] age of patients, 45.5 [13.3] years; 663 609 [63.7%] female patients), 457 016 (43.9%) occurred among individuals aged 18 to 44 years and 583 918 (56.1%) among individuals aged 45 to 64 years. Opioid prescriptions were dispensed for 503 058 procedures (48.3%). Among individuals aged 18 to 44 years, cesarean delivery accounted for the highest proportion of total MMEs dispensed after surgery (19.4% [11 418 658 of 58 825 364 MMEs]). Among individuals aged 45 to 64 years, 4 of the top 5 procedures were common orthopedic procedures (eg, arthroplasty of knee, 9.7% of total MMEs [5 885 305 of 60 591 564 MMEs]; arthroscopy of knee, 6.5% [3 912 616 MMEs]). Conclusions and Relevance: In this cross-sectional study of the distribution of postoperative opioid prescribing in the United States, a small number of common procedures accounted for a large proportion of MMEs dispensed after surgery. These findings suggest that the optimal design and targeting of surgical opioid stewardship initiatives in adults undergoing surgery should focus on the procedures that account for the most opioid dispensed following surgery over the life span, such as childbirth and orthopedic procedures. Going forward, systems that provide periodic surveillance of opioid prescribing and associated harms can direct quality improvement initiatives to reduce opioid-related morbidity and mortality.

Predicting perioperative myocardial injury/infarction after noncardiac surgery in patients under surgical and medical co-management: a prospective cohort study.

BACKGROUND: Perioperative myocardial injury/infarction (PMI) following noncardiac surgery is a frequent cardiac complication. This study aims to evaluate PMI risk and explore preoperative assessment tools of PMI in patients at increased cardiovascular (CV) risk who underwent noncardiac surgery under the surgical and medical co-management (SMC) model. METHODS: A prospective cohort study that included consecutive patients at increased CV risk who underwent intermediate- or high-risk noncardiac surgery at the Second Medical Center, Chinese PLA General Hospital, between January 2017 and December 2022. All patients were treated with perioperative management by the SMC team. The SMC model was initiated when surgical intervention was indicated and throughout the entire perioperative period. The incidence, risk factors, and impact of PMI on 30-day mortality were analyzed. The ability of the Revised Cardiac Risk Index (RCRI), frailty, and their combination to predict PMI was evaluated. RESULTS: 613 eligible patients (mean [standard deviation, SD] age 73.3[10.9] years, 94.6% male) were recruited consecutively. Under SMC, PMI occurred in 24/613 patients (3.9%). Patients with PMI had a higher rate of 30-day mortality than patients without PMI (29.2% vs. 0.7%, p = 0.00). The FRAIL Scale for frailty was independently associated with an increased risk for PMI (odds ratio = 5.91; 95% confidence interval [CI], 2.34-14.93; p = 0.00). The RCRI demonstrated adequate discriminatory capacity for predicting PMI (area under the curve [AUC], 0.78; 95% CI, 0.67-0.88). Combining frailty with the RCRI further increased the accuracy of predicting PMI (AUC, 0.87; 95% CI, 0.81-0.93). CONCLUSIONS: The incidence of PMI was relatively low in high CV risk patients undergoing intermediate- or high-risk noncardiac surgery under SMC. The RCRI adequately predicted PMI. Combining frailty with the RCRI further increased the accuracy of PMI predictions, achieving excellent discriminatory capacity. These findings may aid personalized evaluation and management of high-risk patients who undergo intermediate- or high-risk noncardiac surgery.
