American Society of Anesthesiologists Physical Status Classification as a reliable predictor of postoperative medical complications and mortality following ambulatory surgery: an analysis of 2,089,830 ACS-NSQIP outpatient cases

Preoperative abnormal bone mineral density as a prognostic indicator in patients undergoing gastrectomy for gastric cancer: A cohort study

Predicting postgastrectomy relapse and mortality in patients with gastric cancer (GC) remains challenging, with limitations to traditional staging systems such as the tumor-node-metastasis (TNM) system. This study aimed to investigate the impact of preoperative Hounsfield unit (HU) values, which serve as a surrogate marker for bone mineral density (BMD), in predicting survival outcomes in patients with GC. A retrospective analysis was conducted on data from patients with GC who underwent curative-intent gastrectomy. Opportunistic abdominopelvic computed tomography images were used to assess HU values at the 3rd lumbar vertebra (L3). These values were then categorized using a cutoff value of 110 HU, which has been established in previous studies as a determinant for abnormal versus normal BMD. Cox regression analysis established predictor models for overall survival (OS). Among 501 initial patients, 478 met the inclusion criteria. Multivariate analyses revealed HU values (hazard ratio, 1.51), along with other factors (the 5-factor modified frailty index, type of gastrectomy, TNM stage, anemia, and serum albumin level), as significant predictors of OS. The full model (FM) incorporating these variables demonstrated superior discrimination ability compared to the baseline model (BM), which is based solely on the TNM stage (concordance index: 0.807 vs 0.709; P < .001). Furthermore, the FM outperformed the BM in predicting OS risks at 36- and 60-months post-surgery. In conclusion, among patients undergoing gastrectomy for GC, those with HU values ≤ 110 (indicating abnormal BMD) at the L3 level, as determined through opportunistic CT scans, exhibited a poorer prognosis than those with HU values > 110 (indicating normal BMD). Integrating HU with other clinicopathological parameters enhances predictive accuracy, facilitating individualized risk stratification and treatment decision-making, which could potentially lead to improved survival outcomes.

Developing the Aesthetic Postoperative Complication Score (APeCS) for Detecting Major Morbidity in Facial Aesthetic Surgery

BACKGROUND

Facial aesthetic surgery encompasses a variety of procedures with complication rates that are difficult to estimate due to a lack of published data.

OBJECTIVES

We sought to estimate major complication rates in patients undergoing facial aesthetic procedures and develop a risk assessment tool to stratify patients.

METHODS

We utilized the Tracking Operation and Outcomes for Plastic Surgeons (TOPS) database from 2003-2018. The analytic database included major facial aesthetic procedures. Univariate analysis and a backward stepwise multivariate regression model identified risk factors for major complications. Regression coefficients were utilized to create the score. Performance robustness was measured with area under receiver operating characteristic curves and sensitivity analyses.

RESULTS

A total of 38,569 patients were identified. The major complication rate was 1.2% (460). The regression model identified risk factors including over 3 concomitant surgeries, BMI ≥25, ASA class ≥2, current or former smoker status, and age ≥45 as the variables fit for risk prediction (n = 13,004; area under curve: 0.68, standard error: 0.013, [0.62-0.67]). Each of the 5 variables counted for 1 point, except over 3 concomitant surgeries counting for 2, giving a score range from 0 to 6. Sensitivity analysis showed the cutoff point of ≥3 to best balance sensitivity and specificity, 58% and 66%, respectively. At this cutoff, 65% of cases were correctly classified as having a major complication.

CONCLUSIONS

We developed an acceptable risk prediction score with a cutoff value of ≥3 associated with correctly classifying approximately 65% of those at risk for major morbidity when undergoing face and neck aesthetic surgery.

Obesity Portends Increasing Rates of Superficial Surgical Site Infection Following Pediatric Reduction Mammoplasty: A National Surgical Database Analysis

INTRODUCTION

Pediatric reduction mammoplasty has become increasingly common due to the obesity epidemic. While obesity remains the leading cause of macromastia leading to surgery, it may also be a risk factor for postoperative complications. This study examines the safety of pediatric reduction mammoplasty and the risk of obesity for complications following this procedure.

METHODS

The American College of Surgeons National Surgical Quality Improvement Program Pediatrics was queried to obtain all reduction mammoplasty cases from 2012 to 2020. Univariate and multivariate logistic regression analyses controlling for confounders were carried out to assess the relationship between body mass index (BMI) and rates of complication.

RESULTS

One thousand five hundred eighty-nine patients with the primary Current Procedural Terminology code 19318 were included in the final analysis. The mean age was 16.6 (SD, 1.1) years, and the mean BMI was 30.5 (SD, 6.2) lb/in2. Notably, 49% of the patients were obese, and 31% were overweight, while only 0.4% were underweight. Forty-three patients (2.7%) sustained a superficial surgical site infection (SSI) postoperatively. Other complications were less prevalent, including deep SSI (4 patients, 0.3%), dehiscence (11, 0.7%), reoperation (21, 1%), and readmission (26, 1.6%).Independent variables analyzed included age, sex, BMI, diabetes mellitus, American Society of Anesthesiologists (ASA) class, and operative time, of which only BMI and ASA class were found to be significantly associated with SSI on univariate analysis. On multivariate logistic regression while controlling for ASA class and the false discovery rate, there was a strong association between increasing rates of superficial SSI and increasing BMI (unit odds ratio, 1.05; 95% confidence interval, [1.01, 1.09]; P = 0.02). The OR indicates that for each 1-unit increase in BMI, the odds of SSI increase by 5%.

CONCLUSIONS

Complications following pediatric reduction mammoplasty are uncommon, demonstrating the safety of this procedure. High BMI was found to have a significantly higher risk for superficial SSI. Increased caution and infection prophylaxis should be taken when performing this operation on obese patients.

Community-based prehabilitation in older patients and high-risk patients undergoing colorectal cancer surgery

INTRODUCTION

Prehabilitation before colorectal cancer (CRC) surgery is promising to prevent complications and to enhance recovery, especially in patients aged 70 or older or in patients with an American Society of Anaesthesiologist (ASA) physical classification score 3-4, for whom surgery is associated with higher postoperative complications and long-lasting adverse effects on functional performance.

MATERIALS AND METHODS

A cohort study was conducted in a large teaching hospital in Alkmaar, the Netherlands. Fifty CRC patients (≥70 years or ASA 3-4) underwent multimodal prehabilitation between September 2020 and July 2021. The reference group comprised 50 patients (≥70 years or ASA 3-4) from a historical cohort receiving CRC surgery without prehabilitation (March 2020-August 2020). The primary outcome was 90-day postoperative complication rate. Secondary outcomes were length of stay, 90-day readmission and mortality rates and functional outcome in the prehabilitation group.

RESULTS

One patient in the prehabilitation group decided not to undergo surgery. Of the remaining 49 patients, 48 (98.0 %) received prehabilitation for at least 3 weeks. Of these patients, 32.7 % developed postoperative complications, compared to 58 % in the reference group (p = 0.015), and none were readmitted, in contrast to 6 reference group patients (12.0 %, p = 0.012). Length of stay and mortality did not differ significantly. Six weeks postoperatively, all functional outcomes in the prehabilitation group were significantly higher than at baseline.

CONCLUSIONS

Prehabilitation reduced postoperative complications and improved short-term functional outcomes in older and high-risk patients receiving CRC surgery. Further research should investigate the maintenance of long-term enhanced lifestyle and the effects of tailor-made programs.

Preoperative Frailty Scores Predict the Early Postoperative Complications of Holmium Laser Enucleation of Prostate

Background: Frailty is a recent multidimensional concept of a contemporary growing interest for understanding the complex health status of elderly population. We aimed to assess the impact of frailty scores on the outcome and complication rate of holmium laser enucleation of prostate (HoLEP). Methods: A 7-year data of HoLEP patients in a single tertiary referral center were reviewed. The preoperative, operative, early, and late postoperative outcome data were collected and compared according to the preoperative frailty scores. Frailty was assessed preoperatively using the Modified Hopkins frailty score. Results: The study included 837 patients categorized into two groups: group I included 533 nonfrail patients (frailty score = 0), whereas group II included 304 frail patients (frailty score ≥1). The median (interquartile range) age was 70 (11) and 75 (11) years for groups I and II, respectively (<0.001). The 30-day perioperative complication rate (p = 0.005), blood transfusion (p = 0.013), failed voiding trial (p = 0.0015), and 30-day postoperative readmission (p = 0.0363) rates were significantly higher in frail patients of group II. The two groups were statistically comparable regarding postoperative international prostate symptom score (p = 0.6886, 0.6308, 0.9781), incontinence rate (p = 0.475, 0.592, 0.1546), postvoid residual (p = 0.5801, 0.1819, 0.593) at 6 weeks and 3 months, and 1-year follow-up intervals, respectively. Conclusion: In elderly patients undergoing HoLEP, the preoperative frailty scores strongly correlate with the risk of perioperative complications. Frail patients should be counseled regarding their relative higher risk of early perioperative complications although they gain the same functional profit of HoLEP as nonfrail patients.

Prognostic significance of a five-factor modified frailty index in patients with gastric cancer undergoing curative-intent resection: A cohort study

The 5-factor modified frailty index (mFI-5) evaluates frailty based on variables including functional status, diabetes, chronic obstructive pulmonary disease, congestive heart failure, and hypertension requiring medication. Despite its effectiveness in predicting surgical risk, the potential of mFI-5 as a predictor of long-term survival in patients with gastric cancer (GC) has not been investigated. This study aims to assess the prognostic significance of mFI-5 in patients with GC who have undergone curative-intent gastric resection. Among the 494 patients diagnosed with stage I to III GC, multivariate analysis revealed that age, tumor-node-metastasis (TNM) stage, geriatric nutritional risk index, mFI-5, and the type of gastrectomy were significant predictors for both overall survival (OS) and disease-free survival (DFS). We assessed 3 models: Baseline model (BM, TNM stage only), interim model (IM, all significant variables except mFI-5), and full model (FM, all significant variables including mFI-5). FM outperformed BM for OS (C-index 0.818 vs 0.683; P < .001) and DFS (C-index 0.805 vs 0.687; P < .001). Similarly, IM outperformed BM for OS (C-index 0.811 vs 0.683; P < .001) and DFS (C-index 0.797 vs 0.687; P < .001). Multiple metrics consistently supported the improved discriminative capacity of FM and IM compared to BM. However, while FM exhibits enhanced predictive capacity over IM, this improvement lacks statistical significance across key metrics. In conclusion, our study highlights the clinical significance of the mFI-5, along with age, TNM stage, geriatric nutritional risk index, and type of gastrectomy, as valuable predictors of long-term survival in GC patients. The FM consistently demonstrates enhanced predictive accuracy compared to the BM. However, it is important to note that while the FM improves predictive power over the IM, this enhancement does not achieve statistical significance across multiple metrics. These findings collectively emphasize the potential clinical value of the FM as a robust tool for surgeons in predicting long-term survival outcomes before surgery in patients with GC.

Association Between Metabolic Syndrome and Outcomes in Complex Head and Neck Surgery

OBJECTIVES

We aim to evaluate the impact of MetS on the short-term postoperative outcomes of complex head and neck surgery patients.

METHODS

This is a retrospective cohort analysis of the 2005 to 2017 National Surgical Quality Improvement Program (NSQIP) database. NSQIP database was queried for 30-day outcomes of patients undergoing complex head and neck surgeries, defined as laryngectomy or mucosal resection followed by free tissue transfer, similar to prior NSQIP studies. Patients with hypertension, diabetes, and body mass index (BMI) >30 kg/m2 were defined as having MetS. Adverse events were defined as experiencing readmission, reoperation, surgical/medical complications, or mortality.

RESULTS

A total of 2764 patients (27.0% female) with a mean age of 62.0 ± 11.7 years were included. Patients with MetS (n = 108, 3.9%) were more likely to be female (P = .017) and have high ASA classification (P = .030). On univariate analysis, patients with MetS were more likely to require reoperation (25.9% vs 16.7%, P = .013) and experience medical complications (26.9% vs 15.4% P = .001) or any adverse events (61.1% vs 48.7%, P = .011) compared to patients without MetS. On multivariate logistic regression after adjusting for age, sex, race, ASA classification, and complex head and neck surgery type, MetS was an independent predictor of medical complications (odds ratio 2.34, 95% CI 1.28-4.27, P = .006).

CONCLUSION

Patients with MetS undergoing complex head and neck surgery are at increased risk of experiencing medical complications. Identifying patients with MetS can therefore aid surgeons in preoperative risk assessment and help improve postoperative management.

The ASA Classification System as a Predictive Factor to Stay at the Virtual Hybrid Care Hotel

INTRODUCTION

The Care Hotel is a virtual hybrid care model for postoperative patients after low-risk procedures which allow recovery in an outpatient environment. This study aimed to analyze if the American Society of Anesthesiologists Physical Status (ASA PS) Classification System can be used as a predictive factor for staying at Mayo Clinic's Care Hotel.

METHODS

This retrospective cohort study was conducted between July 23, 2020, and June 4, 2021, at Mayo Clinic in Florida, a 306-bed community academic hospital. ASA PS Class and post-procedure care setting (Care Hotel vs inpatient ward) were collected. Patients were classified into two ASA PS groups (ASA PS Classes 1-2 and 3-4). Pearson's Chi-square test was used to determine if the ASA PS Class and having stayed or not at the Care Hotel were independent and an Odds Ratio (OR) calculated.

RESULTS

Out of 392 surgical and procedural patients, 272 (69.39%) chose the Care Hotel and 120 (30.61%) chose the inpatient ward. There was a statistically significant association between ASA PS Class and staying at the Care Hotel, P < .01. The OR of preferring to stay at the Care Hotel in patients with ASA PS Class 1-2 vs ASA PC Class 3-4 was 1.91 (P = .0041, 95% CI: 1.229-2.982).

CONCLUSION

Patients with ASA PS Classes 1-2 are almost twice as likely to elect to stay at the Care Hotel compared to those with ASA PS Classes 3-4. This finding may help care teams focus their Care hotel recruitment efforts.

Preoperative admission is non-essential in most patients receiving elective laparoscopic cholecystectomy: A cohort study

We evaluated conventional overnight-stay laparoscopic cholecystectomy, focusing on the preoperative admission day, to assess the feasibility of implementing daycare laparoscopic cholecystectomy, which is currently underutilized in developing and some Asian countries. We retrospectively reviewed elective laparoscopic cholecystectomy data from March 2020 to February 2022 at a 700-bed tertiary hospital in Thailand. Variables included age, sex, body mass index, comorbidities, American Society of Anesthesiologists status, presence of preoperative anesthesiology visit, laparoscopic cholecystectomy indications, additional intraoperative cholangiography, and surgery cancellations. The primary focus was on preoperative treatment and monitoring needs; secondary outcomes included morbidity, mortality within 30 days, and prolonged hospital stay (>48 hours). Statistical analysis was conducted using the Fisher exact test, t-test, and logistic regression. The study included 405 patients. Of these, 65 (16.1%) received preoperative treatment, with 21 unnecessary (over) treatments and six under-treatments. Based on the results, approximately 12.1% (n = 49) of patients may have theoretically required preoperative admission and treatment. Multivariable analysis showed that the increasing of comorbidities was significantly associated with preoperative management (odds ratio [95% Confidence interval]: 7.0 [2.1, 23.1], 23.9 [6.6, 86.6], 105.5 [17.5, 636.6]) for one, two, and three comorbidities, respectively), but factors such as age, obesity, and American Society of Anesthesiologists status were not. The cohort had 4.2% morbidity (2.2% medical complications), with no mortality. Surgery cancellations occurred in 0.5%. In conclusion, on the basis of our data, a small proportion (12.1%) of patients undergoing elective laparoscopic cholecystectomy may require preoperative admissions to receive the necessary treatment, and most (87.9%) preoperative admissions may not provide treatment benefit. The traditional admission approach was safe but required re-evaluation for optimal resource management.

The patient with congenital heart disease in ambulatory surgery

The number of patients with congenital heart disease (CHD) undergoing ambulatory surgery is increasing. Deciding whether a CHD patient is suitable for an ambulatory procedure is still challenging. Several factors must be considered, including the type of planned procedure, the complexity of the underlying pathology, the American Society of Anesthesiologists' Physical Status classification of the patient, and other patient-specific factors, including comorbidity, chronic complications of CHD, medication, coagulation disorders, and issues related to the presence of a pacemaker (PM) or cardioverter-defibrillator. Numerous studies reported higher perioperative mortality and morbidity rates in surgical patients with CHD than non-CHD patients. However, most of these studies were conducted in a cohort of hospitalized patients and may not reflect the ambulatory setting. The current review aims to provide the anesthesiologist with an overview and practical recommendations on selecting and managing a CHD patient scheduled for an ambulatory procedure.

Preoperative risk factors and postoperative complications associated with mortality after outpatient surgery in a broad surgical population: an analysis of 2.8 million ACS-NSQIP patients

BACKGROUND

Thirty-day mortality after outpatient surgery is unexpected and undesired. We investigated preoperative risk factors, operative variables, and postoperative complications associated with 30-day death after outpatient surgery.

METHODS

Using the 2005 to 2018 American College of Surgeons National Surgical Quality Improvement Program database, we evaluated 30-day mortality rate trends over time after outpatient operations. We analyzed associations between 37 preoperative variables, operation time, hospital length of stay, and 9 postoperative complications with mortality rate using χ2 analyses for categorical data and tests for continuous data. We used forward selection logistic regression models to determine the best predictors of mortality preoperatively and postoperatively. We also separately analyzed mortality by age group.

RESULTS

A total of 2,822,789 patients were included. The 30-day mortality rate did not change significantly over time (P = .34, Cochran-Armitage trend test), remaining steady at around 0.06%. The most significant preoperative predictors of mortality included the patient having disseminated cancer, decreased functional health status, increased American Society of Anesthesiology Physical Status classification, increased age, and ascites, accounting for 95.8% (0.837/0.874) of the full model c-index. The most significant postoperative complications associated with increased risk of mortality included having cardiac (26.95% yes vs 0.04% no), pulmonary (10.25% vs 0.04%), stroke (9.22% vs 0.06%), and renal (9.33% vs 0.06%) complications. Postoperative complications conferred a greater risk for mortality than preoperative variables. Mortality risk increased incrementally with age, particularly past age 80.

CONCLUSION

The operative mortality rate after outpatient surgery has not changed over time. Patients over 80 years with disseminated cancer, decreased functional health status, or increased ASA class should generally be considered for inpatient surgery. However, there might be some circumstances where outpatient surgery could be considered.

Local anesthesia for Altis® single incision sling in women with stress urinary incontinence

OBJECTIVE

Local anesthesia for single incision slings has shown a good objective and subjective cure rate in women with stress urinary incontinence. The aim of the present study was to verify the efficacy and safety of local anesthesia during Altis® single incision placement.

MATERIAL AND METHODS

One hundred sixty-six consecutive patients (83 patients for each group: local resp. spinal anesthesia) were selected from our database for this retrospective study among women who underwent an Altis® implantation for SUI from September 2016 to June 2021, after unsuccessful previous conservative treatment. Primary endpoints were objective and subjective cure rates; secondary endpoint was the evaluation of complications linked to this procedure.

RESULTS

A total of 155 included patients completed our 12 months follow-up. Baseline characteristics were similar between the groups. Operative time (percentage difference of 50%; p < 0.05) and the Intraoperative Difficulty Scale resulted lower in spinal patients. No differences were found between populations in terms of objective (cough stress test and urodynamics) and subjective (PGI-I and FSDS questionnaires) cure rate and postoperative complications.

CONCLUSION

Local anesthesia for Altis® implantation could be considered a safe alternative to spinal anesthesia and an effective opportunity to avoid general anesthesia, increasing the possibility of outpatient implantation of this sling system.

Postoperative pulmonary complications in severe acute respiratory syndrome coronavirus 2 infected patients who underwent emergency surgery

BACKGROUND

Recent studies suggest that severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection increases the incidence of postoperative pulmonary complications (PPCs) and mortality. Consequently, patients with SARS-CoV-2 infection undergoing emergency surgery are more vulnerable to PPCs, yet few studies have evaluated PPCs in these patients.

METHODS

A retrospective analysis was conducted between January 2022 and February 2023 on the medical records of patients infected with SARS-CoV-2 who underwent emergency surgery. The study evaluated the incidence of PPCs and 30-day postoperative mortality in all enrolled patients.

RESULTS

A total of 41 patients were enrolled, among whom PPCs occurred in seven patients (17%). The incidence of PPCs was statistically significant in patients with underlying diabetes compared to those without (p = 0.01) and in patients with an American Society of Anesthesiologists (ASA) class 3 or higher compared to those with less than 3 (p = 0.005) (ASA classification uses a grading system of I (one) through V (five)). The 30-day mortality rate was 4.9%.

CONCLUSIONS

Our study demonstrates that the incidence of PPCs and 30-day mortality rates after emergency surgery in patients infected with SARS-CoV-2 are higher compared to prepandemic baseline rates. Given the significant interest and concern worldwide regarding severe infectious respiratory diseases, such as coronavirus disease 2019 (COVID-19), clinicians should focus on conducting research to identify ways to reduce the incidence of PPCs and mortality in patients with severe acute respiratory infections.

Mid- to Long-Term Survival of Geriatric Patients with Primary Septic Arthritis of the Shoulder: A Retrospective Study over a Period of 20 Years

Septic arthritis of the shoulder is an urgent medical emergency that often occurs in elderly patients and is associated with high morbidity and mortality. Retrospectively, 56 patients aged ≥60 years, treated for primary septic monoarthritis of the shoulder at a maximum care hospital between 1 July 2001, and 30 July 2022, were included in this study. The primary aim of the study was analyzing survival rates and different bacteria in these patients. For statistical analysis, Kaplan-Meier curves were used for survival probability and the log-rank test was used to compare a survival probability of 5 years. The mean patient age was 78.7 years and a mean follow-up time of 3011.8 days. The mean survival of the entire study population was 920.3 days or 2.5 years. Significantly impaired 5-year survival was found only with increasing age and higher American Society of Anesthesiologists (ASA) physical status (PS) classification scores. Eight different types of bacteria were detected in the synovial fluid cultures. A total of 42 of 48 overall pathogens was Gram-positive and 6 were Gram-negative bacteria. Staphylococcus aureus was identified as the most frequent variant. We conclude that the mean survival is significantly shortened within the first 5 years with increasing age and ASA PS classification.

Recent COVID-19 infection is associated with increased mortality in the ambulatory surgery population

BACKGROUND

The effect of COVID-19 infection on post-operative mortality and the optimal timing to perform ambulatory surgery from diagnosis date remains unclear in this population. Our study was to determine whether a history of COVID-19 diagnosis leads to a higher risk of all-cause mortality following ambulatory surgery.

METHODS

This cohort constitutes retrospective data obtained from the Optum dataset containing 44,976 US adults who were tested for COVID-19 up to 6 months before surgery and underwent ambulatory surgery between March 2020 to March 2021. The primary outcome was the risk of all-cause mortality between the COVID-19 positive and negative patients grouped according to the time interval from COVID-19 testing to ambulatory surgery, called the Testing to Surgery Interval Mortality (TSIM) of up to 6 months. Secondary outcome included determining all-cause mortality (TSIM) in time intervals of 0-15 days, 16-30 days, 31-45 days, and 46-180 days in COVID-19 positive and negative patients.

RESULTS

44,934 patients (4297 COVID-19 positive, 40,637 COVID-19 negative) were included in our analysis. COVID-19 positive patients undergoing ambulatory surgery had higher risk of all-cause mortality compared to COVID-19 negative patients (OR = 2.51, p < 0.001). The increased risk of mortality in COVID-19 positive patients remained high amongst patients who had surgery 0-45 days from date of COVID-19 testing. In addition, COVID-19 positive patients who underwent colonoscopy (OR = 0.21, p = 0.01) and plastic and orthopedic surgery (OR = 0.27, p = 0.01) had lower mortality than those underwent other surgeries.

CONCLUSIONS

A COVID-19 positive diagnosis is associated with significantly higher risk of all-cause mortality following ambulatory surgery. This mortality risk is greatest in patients that undergo ambulatory surgery within 45 days of testing positive for COVID-19. Postponing elective ambulatory surgeries in patients that test positive for COVID-19 infection within 45 days of surgery date should be considered, although prospective studies are needed to assess this.

Factors Associated With Poor Patient-Reported Outcomes in Isolated Gastrocnemius Recession for Heel Pain

Background

Gastrocnemius recession is commonly performed for a variety of pathologies of the foot and ankle, yet studies characterizing risk factors associated with patient-reported outcomes are limited. In this cohort study, patient outcomes were compared against the general population for PROMIS scores with correlation analysis comparing demographics and comorbidities. Our primary goal in this study is to identify risk factors associated with poor patient-reported outcomes following isolated gastrocnemius recession for patients with plantar fasciitis or insertional Achilles tendinopathy.

Methods

A total of 189 patients met inclusion criteria. The open Strayer method was preferred. However, if the myotendinous junction could not be adequately visualized without expanding the excision, then a Baumann procedure was performed. The decision between the two did not depend on preoperative contracture. Patient demographics and visual analog scale (VAS) scores were obtained via the electronic medical record. Telephone interviews were completed to collect postoperative Patient-Reported Outcomes Measurement Information System (PROMIS) and Foot Function Index (FFI) scores. The data were analyzed using the type 3 SS analysis of variance test to identify individual patient factors associated with reduced PROMIS, FFI, and VAS scores.

Results

No demographic variables were found to be significantly associated with postoperative complications. Patients who reported tobacco use at the time of surgery had significantly decreased postoperative PROMIS physical function (P = .01), PROMIS pain interference (P < .05), total FFI scores (P < .0001), and each individual FFI component score. Patients undergoing their first foot and ankle surgeries reported numerous significant postoperative outcomes, including decreased PROMIS pain interference (P = .03), higher PROMIS depression (P = .04), and lower FFI pain scores (P = .04). Hypertension was significantly associated with an increased FFI disability score (P = .03) and, along with body mass index (BMI) >30 (P < .05) and peripheral neuropathy (P = .03), significantly higher FFI activity limitation scores (P = .01). Pre- and postoperative VAS scores demonstrated improvement in patient-reported pain from a mean of 5.53 to 2.11, respectively (P < .001).

Conclusion

We found in this cohort that numerous patient factors were independently associated with differences in patient-reported outcomes following a Strayer gastrocnemius recession performed for plantar fasciitis or insertional Achilles tendinopathy. These factors include, but are not limited to, tobacco use, prior foot and ankle surgeries, and BMI. This study strengthens previous reports demonstrating the efficacy of isolated gastrocnemius recession and elucidates variables that may affect patient-reported outcomes.

Quality of recovery after day care surgery with app-controlled remote monitoring: study protocol for a randomized controlled trial

BACKGROUND

The majority of surgical interventions are performed in day care and patients are discharged after the first critical postoperative period. At home, patients have limited options to contact healthcare providers in the hospital in case of severe pain and nausea. A smartphone application for patients to self-record pain and nausea when at home after day care surgery might improve patient's recovery. Currently patient experiences with smartphone applications are promising; however, we do not know whether remote monitoring with such an application also improves the patient's recovery. This study aims to evaluate the experienced quality of recovery after day care surgery between patients provided with the smartphone application for remote monitoring and patients receiving standard care without remote monitoring.

METHODS

This non-blinded randomized controlled trial with mixed methods design will include 310 adult patients scheduled for day care surgery. The intervention group receives the smartphone application with text message function for remote monitoring that enables patients to record pain and nausea. An anaesthesia professional trained in empathetic communication, who will contact the patient in case of severe pain or nausea, performs daily monitoring. The control group receives standard care, with post-discharge verbal and paper instructions. The main study endpoint is the difference in perceived quality of recovery, measured with the QoR-15 questionnaire on the 7th day after day care surgery. Secondary endpoints are the overall score on the Quality of Recovery-15 at day 1, 4 and 7-post discharge, the perceived quality of hospital aftercare and experienced psychological effects of remote monitoring during postoperative recovery from day care surgery.

DISCUSSION

This study will investigate if facilitating patients and healthcare professionals with a tool for accessible and empathetic communication might lead to an improved quality of the postoperative recovery period.

TRIAL REGISTRATION

The 'Quality of recovery after day care surgery with app-controlled remote monitoring: a randomized controlled trial' is approved and registered on 23 February 2022 by Research Ethics Committees United with registration number R21.076/NL78144.100.21.

Risk factors associated with venous thromboembolism in laparoscopic surgery in non-obese patients with benign disease

INTRODUCTION

Few studies have focused on intraoperative positioning as a risk factor for venous thromboembolism (VTE). Positioning that places the legs in a dependent position may be a risk factor. We theorized that the reverse-Trendelenburg position specifically would increase the risk of postoperative VTE.

METHODS AND PROCEDURES

374,017 subjects undergoing laparoscopic surgery in the 2015-2018 NSQIP database were included. Diagnosis of cancer and BMI ≥ 30 were excluded. Subjects were grouped based on positioning: reverse-Trendelenburg (RT), supine (S), and Trendelenburg (T).

RESULTS

The RT, S, and T groups consisted of 117,887, 66,511, and 189,619 subjects, respectively. Overall median BMI was 25.7, and 82.8% of subjects were non-smokers. VTE within 30 days postoperative was seen in 0.25% RT, 0.23% S, and 0.4% T (p < 0.0001); 30-day mortality was 0.34% RT, 0.25% S, and 0.19% T (p < 0.0001). After adjusting for potential confounders and other risk factors, RT position was associated with a lower risk of VTE compared to S (OR 1.49 with 95% CI 1.16, 1.93) and T (OR 1.34 with 95% CI 1.15, 1.56) positions. VTE risk was significantly different across the three groups (p = 0.0001). Inpatient procedures had a higher VTE risk vs outpatient (OR 2.49 with 95% CI 2.10, 2.95). Increasing operative time was associated with higher VTE risk [4th (> 106 min) vs 1st (≤ 40 min) quartiles (OR 3.54 with 95% CI 2.79, 4.48)].

CONCLUSIONS

Among other risk factors, inpatient procedures and longer operative times are associated with higher VTE risk in laparoscopic surgery performed for benign disease in non-obese patients. The risk was significantly different across the three positioning groups with lowest risk in the RT group and highest risk in the S group.

Individualized Care and Follow-Up in Outpatient Surgery: A Pilot Study

Introduction In outpatient surgery, post-discharge follow-up calls are essential for identifying complications and are considered a cost-effective intervention. Currently, there is a lack of scientific evidence to support the development and validation of standardized protocols adjusted to patients' specificities. Our aim is to develop a personalized model for our outpatient surgery unit (OSU) to create an individualized follow-up strategy in the future. Material and methods We performed a retrospective, cohort, single-center study, including patients undergoing surgery at an OSU of a tertiary hospital in Portugal, for three months. Follow-up calls were performed on the seventh and fourteenth days after discharge. The variables analyzed included: sex, age, surgical specialty, anesthetic technique, American Society of Anesthesiologists (ASA) physical status classification, surgery duration, and complications. A binary logistic regression was adjusted for the complications detected in each call. Results Nine-hundred eighty-four (984) patients were included, of which 79.8% (n=785) and 75.3% (n=741) answered the follow-up calls on the seventh and fourteenth days after discharge, respectively. Complications were reported in 47.1% (n=370) and 29.8% (n=221) of these calls, respectively, with pain having the highest incidence rate (44.7% in the first call; 26.6% in the second). The type of anesthesia and surgical specialty were independent risk factors for complications (p<0.001). Each minute increase in surgery duration increased by 1.1% the odds of complications (95% confidence interval 1.003-1.018) in the first call. Compared with no anesthesiology involvement, general anesthesia, regional anesthesia, and monitored anesthetic care are 2.52, 2.04, and 1.75 times more likely to have complications detected in the first call and 3.21, 2.36, and 3.11 times more likely to have complications on the second (p<0.05 for all). A model that predicts the detection of complications in each call was created. Discussion Outpatient surgery may allow procedures to be carried out safely, efficiently, and cost-effectively. To optimize the outcomes, it is important to quantify results as a tool for honing our strategies. The present study recognized the influence of several variables in the incidence of post-discharge complications. Also, considering the complications reported, pain was the most frequent among the reports and should not be neglected. In our reality, no follow-up calls are routinely performed after the seventh day, and complications were reported in that period, meaning some patients probably should be accompanied for a longer period. Conclusions To ensure the quality of care and patient safety and satisfaction, it is essential to identify and manage postoperative complications. Despite not being a routine contact, the incidence rate of complications on the seventh and fourteenth postoperative days is noted. According to our investigation, the type of anesthesia, surgical specialty, and duration of surgery should be carefully considered when establishing individualized follow-up plans. These plans, using tools adjusted to the population of each OSU, such as the calculator presented, may allow the available resources to be used with the greatest potential benefit for both patients and healthcare systems.

Risk factors for ninety-day readmission following cervical surgery: a meta-analysis

Background

As an important evaluation index after cervical surgery, ninety-day readmission is gradually being valued. Our study collected the latest published relevant studies, analyzed the risk factors of ninety-day readmission after cervical surgery, and continuously improved the postoperative rehabilitation plan. This study focuses on two research hotspots: (1) What is the rate of ninety-day readmission after cervical surgery? (2) What are the risk factors affecting the ninety-day readmission?

Methods

Based on the Cochrane Library, PubMed, Web of Science, and Embase databases, this study searched for studies about ninety-day readmission after cervical surgery, from the establishment of the database to August 1, 2022. The evaluation indicators are as follows: age, American Society of Anesthesiology physical status (ASA) class, diabetes, hypertension, chronic heart diseases, chronic lung diseases, income, and payments for hospitalization. The meta-analysis was performed using Review Manager 5.4.

Results

Seven studies with 222,490 participants were eligible for our meta-analysis. The analysis displayed that there were statistically significant differences in the age (MD = − 4.60, 95%CI − 4.89–4.31, p < 0.001), diabetes (OR = 0.60, 95%CI 0.56–0.64, p < 0.00001), hypertension (OR = 0.40, 95%CI 0.30–0.54, p < 0.00001), chronic heart diseases (OR = 0.05, 95%CI 0.01–0.19, p < 0.00001), chronic lung diseases (OR = 0.46, 95%CI 0.43–0.49, p < 0.00001), income (OR = 2.85, 95%CI 1.82–4.46, p < 0.00001), and payments for hospitalization (OR = 2.29, 95%CI 1.14–4.59, p = 0.02) between readmission and no readmission groups. In terms of the ASA, there was no difference on the ninety-day readmission (p = 0.78).

Conclusion

Age, diabetes, hypertension, chronic heart diseases, chronic lung diseases, income, and payments for hospitalization are the risk factors of ninety‐day readmission following cervical surgery.

The impact of the American Society of Anesthesiology-Physical Status classification system on the treatment and prognosis of patients with esophageal cancer undergoing esophagectomy

BACKGROUND

The American Society of Anesthesiologists-Physical Status (ASA-PS) classification system has been shown to predict morbidity and mortality after surgery. However, the impact of the ASA-PS on esophageal cancer treatment remains unclear. This study examined both the impact of the ASA-PS on treatment, including surgery and perioperative chemotherapy, and the prognostic effects of ASA-PS class in patients who had undergone esophagectomy for thoracic esophageal cancer or esophagogastric junction cancer.

METHODS

ASA-PS status was collected for 301 patients who had undergone esophagectomy between January 2007 and June 2016 for thoracic esophageal cancer or esophagogastric junction cancer at a single institution. As the ASA-PS was updated in 2014, the previous classifications of all patients were reevaluated using the updated standard by a surgeon with the previous classifications masked. The dose intensity of preoperative chemotherapy was also compared across classes. Multivariate Cox regression analysis was used to analyze the association between ASA-PS class and overall survival.

RESULTS

Patients whose reevaluations had placed them in a more severe ASA-PS class showed significantly poorer overall and cancer-specific survival rates. The dose intensities of cisplatin and 5-fluorouracil for preoperative chemotherapy were significantly lower in patients in the more severe ASA-PS classes. Multivariate analysis showed that ASA-PS class was an independent prognostic factor for overall survival.

CONCLUSION

Preoperative ASA-PS classification may influence the intensity of perioperative treatment and may be a valuable long-term prognostic factor for patients with esophageal cancer undergoing esophagectomy.

A Virtual Hybrid Care Hotel Model Supports the Recovery of Post-procedural Patients with Mild to Severe Systemic Diseases

BACKGROUND

Patients with mild to severe chronic systemic disease undergoing low-risk procedures are often hospitalized for observation. The Care Hotel is a novel virtual medicine hybrid model of care that offers patients a comfortable, out of hospital environment where they can receive both in-person and virtual care after a surgery or procedure. This study aimed to analyze if virtual hybrid post-procedure care in a hotel could be both conducted on and accepted by patients, even those with moderate to severe chronic diseases.

METHODS

This retrospective cohort study was conducted between July 23, 2020 and June 4, 2021 at Mayo Clinic in Florida, a 306-bed community academic hospital. We collected the sex, age, race, ethnicity, acceptance rate, ASA score, and primary procedure of patients using the Care Hotel.

RESULTS

Out of 392 patients, 272 (69.4%) opted for care in the program. Median patient age was 61.5 years, 59.56% were males, and 86.40% were white. We found that 50.37% had an ASA score of 2 and 43.4% had an ASA score of 3. Ten different surgical specialties were able to utilize the Care Hotel for care in 47 different procedure types. Urology had the most patients (n=70, 25.7%). Post-electrophysiologic procedures were the most common procedures (n=39, 14.3%).

CONCLUSION

Our virtual hybrid Care Hotel program was widely accepted by patients and could care for a multitude of post-operative procedures. Additionally, this novel program can care for patients with both mild and severe systemic diseases.

Emergencies in freestanding ambulatory surgery centre

PURPOSE OF REVIEW

Ambulatory surgery is increasing, more procedures as well as more complex procedures are transferred to ambulatory surgery. Patients of all ages including elderly and more fragile are nowadays scheduled for ambulatory surgery. Enhanced recovery after surgery (ERAS) protocols are now developed for further facilitating readily recovery, ambulation, and discharge. Thus, to secure safety, a vigilant planning and preparedness for adverse events and emergencies is mandatory.

RECENT FINDINGS

Proper preoperative assessment, preparation/optimization and collaboration between anaesthetist and surgeon to plan for the optimal perioperative handling has become basic to facilitate well tolerated perioperative course. Standard operating procedures for rare emergencies must be in place. These SOPs should be trained and retrained on a regular basis to secure safety. Check lists and cognitive aids are tools to help improving safety. Audit and analysis of adverse outcomes and deviations is likewise of importance to continuously analyse and implement corrective activity plans whenever needed.

SUMMARY

The present review will provide an oversight of aspects that needs to be acknowledged around planning handling of rare but serious emergencies to secure quality and safety of care in freestanding ambulatory settings.

Class 3 obesity is not associated with same-day admission in obese patients undergoing parathyroidectomy

IMPORTANCE

Rising rates of obesity and outpatient performance of parathyroidectomies are making it increasingly crucial to investigate the association of obesity with post-operative complications.

OBJECTIVE

To determine whether Class 3 obesity is associated with increased same-day admission compared to lower obesity classes following outpatient parathyroidectomy.

DESIGN

Retrospective cohort study.

SETTING

Outpatient surgery.

PATIENTS

12,973 patients ≥18 years old who underwent outpatient parathyroidectomy between 2014 and 2016, per the American College of Surgeons National Surgical Quality Improvement Program registry.

INTERVENTIONS

Primary exposure variable: body mass index (BMI), with patients assigned to one of six cohorts.

MEASUREMENTS

Primary outcome measure: same-day admission. Secondary outcome measure: 30-day readmission. Logistic regression was used to calculate odds ratios (OR) and 95% confidence intervals (CI).

MAIN RESULTS

There was a final sample size of 12,973 adult patients who underwent parathyroidectomy from 2014 to 2016. The admission rate for BMI ≥30 and < 40 kg/m² (reference cohort) was 42.6%. The admission rates for Class 3 obesity categories were 46.2%, 56.2%, and 52.6% for those in the BMI range of ≥40 kg/m² and < 50 kg/m², ≥50 kg/m² and < 60 kg/m², and ≥ 60 kg/m², respectively. On multivariable logistic regression, there were no difference in the odds of 30-day hospital admission or readmission rate with any of the BMI cohorts when compared to the reference group.

CONCLUSIONS

There is no significant difference in rates of same-day admission or 30-day readmission between any Class 3 (BMI ≥40 kg/m²) obesity cohort and the Class 1 and 2 (BMI ≥30 and < 40 kg/m²) reference cohort following outpatient parathyroidectomy. This corroborates the notion that BMI classes cannot be used in a vacuum to determine eligibility for outpatient parathyroidectomy - a concept that can guide safe and cost-effective institutional practices.
