[PMID: 39272014 PMCID: PMC11401255 DOI: 10.1186/s12890-024-03274-5] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/26/2023] [Accepted: 09/04/2024] [Indexed: 09/15/2024] Open
Abstract
OBJECTIVE This study aimed to determine the prevalence of polypharmacy, comorbidities and to investigate factors associated with polypharmacy among adult patients with Chronic Obstructive Pulmonary Disease (COPD). METHODS This was a retrospective single-centre cross-sectional study. Patients with a confirmed diagnosis of COPD according to the GOLD guidelines between 28 February 2020 and 1 March 2023 were included in this study. Patients were excluded if a pre-emptive diagnosis of COPD was made clinically without spirometry evidence of fixed airflow limitation. Population characteristics were presented as frequency for categorical variable. Logistic regression analysis was used to identify predictors of polypharmacy. RESULTS The study sample included a total of 705 patients with COPD. Most of the study sample were males (60%). The mean age of the study population was 65 years old. The majority of the study population had comorbid diseases (68%), hypertension and diabetes were the most common co-existent diseases. Around 55% of the study sample had polypharmacy. Females were significantly less likely to be on polypharmacy compared to males (OR = 0.68, 95% CI = [0.50-0.92], P-value = 0.012)). On the other hand, older patients aged 65.4 or more (OR = 2.31, 95% CI = [1.71-3.14], P-value ≤ 0.001), those with high BMI (≥ 29.2) (OR = 1.42, 95% CI = [1.05-1.92], P-value = 0.024), current smokers (OR = 1.9, 95% CI = [1.39-2.62], P-value ≤ 0.001), those who are receiving home care (OR = 5.29, 95% CI = [2.46-11.37], P-value ≤ 0.001), those who have comorbidities (OR = 19.74, 95% CI = [12.70-30.68], P-value ≤ 0.001) were significantly more likely to be on polypharmacy (p ≤ 0.05). CONCLUSIONS Polypharmacy is common among patients with COPD. Patients with high BMI, previous ICU hospitalization and older age are more likely to have polypharmacy. Future analytical studies are warranted to investigate outcomes in patients with COPD and polypharmacy.

Palmer S, Plymale M, Mangino A, Davenport D, Roth JS. Prescription opioid use increases resource utilization following ventral hernia repair. J Gastrointest Surg 2024; 28:483-487. [PMID: 38583899 DOI: 10.1016/j.gassur.2024.01.030] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/09/2023] [Revised: 01/21/2024] [Accepted: 01/26/2024] [Indexed: 04/09/2024]
Abstract
BACKGROUND Previous studies showed that preoperative opioid use is associated with increased postoperative opioid use and surgical site infection (SSI) in patients undergoing ventral hernia repair (VHR). Orthopedic surgery literature cites increased resource utilization with opioid use. This study aimed to determine the effect of preoperative opioid use on resource utilization after open VHR. METHODS A retrospective institutional review board-approved study of VHRs from a single tertiary care practice between 2013 and 2020 was performed. Medical records, the National Surgical Quality Improvement Program database, and Kentucky All Schedule Prescription Electronic Reporting data were reviewed for patient demographics, comorbidities, dispensed opiate prescriptions, hernia characteristics, and outcomes. Univariate logistic regression analyses assessed the effect of each patient's demographic and clinical characteristics. Multivariate logistic regression models analyzed significant factors from the univariate analyses. The primary outcome was resource utilization measured as readmission, emergency department visit, or >2 postoperative clinic visits within 45 days after VHR. RESULTS Overall, 381 patients who underwent VHR were identified; of which 101 patients had preoperative dispensed opioids. Multivariate analysis demonstrated that patient gender at birth, any new-onset SSI, and any preoperative opioid use were associated with increased postoperative resource utilization (odds ratio, 1.76; P = .026). CONCLUSION Preoperative opioid use was determined as a risk factor that increased resource utilization after open VHR. An understanding of the drivers of the increased use of resources is essential in developing strategies to improve healthcare value. Future research will focus on strategies to reduce the utilization of resources among patients who use opioids.

Abstract
INTRODUCTION Several quality indices have been set up for evaluating the impact of the reduction of the length of stay (LOS), such as the 30-day unplanned readmission (UR30) rate. The main goal of our study was to analyze the UR30 following groin hernia repair (GHR), primary- (PVHR), and incisional ventral hernia repairs (IVHR). METHODS A French registry-based multicenter study was conducted using prospective data from all consecutive patients registered from 2015 to 2021. RESULTS The overall incidence of UR30 was 1.32%. This included 160/18,042 (0.87%) for GHR, 41/4012 (1.02%) for PVHR, and 145/3754 (3.86%) for IVHR. The leading cause of UR30 was postoperative complications (POC). The nature of the predominant complications varied among the three categories. The correlation between UR30 and POC (and risk factors for POC) was strong in GHR but was not in IVHR due to a 'protective' longer LOS in this subgroup. As the LOS has decreased over the last years, this has 'mechanically' resulted in an increase in the occurrence of UR30, but not in a rise of POC, neither in volume nor in severity. The reduction of LOS just shifted the problem from inpatient to outpatient settings. CONCLUSION Since the steady development of day-care surgery, the prevention of the UR not only hinges on the prevention of the POC but newly on a better organization of outpatient care which is currently a huge challenge due to a GPs' and nurses' shortage in France.

Early wound morbidity and clinical outcomes associated with P4HB mesh compared to permanent synthetic mesh in umbilical and small to medium, routine ventral hernia repairs. Front Surg 2023; 10:1280991. [PMID: 37881240 PMCID: PMC10595000 DOI: 10.3389/fsurg.2023.1280991] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/21/2023] [Accepted: 09/22/2023] [Indexed: 10/27/2023] Open
Abstract
Background Permanent synthetic meshes such as polypropylene (PP) have been utilized for hernia repair for decades, but concerns remain regarding potential long-term, mesh-related complications. A resorbable polymer such as poly-4-hydroxybutyrate (P4HB) represents an alternative with high initial strength, that gradually resorbs, leaving an abdominal wall that is at least as strong as it would be in its native state. We aimed to compare early wound morbidity and clinical outcomes associated with P4HB to traditional, permanent PP in umbilical and small to medium, routine ventral hernias using data from the Abdominal Core Health Quality Collaborative (ACHQC). Methods Inclusion criteria for the umbilical cohort included: all Centers for Disease Control and Prevention (CDC) wound classes, all Ventral Hernia Working Group (VHWG) hernia grades, and hernia defects <3 cm. The small to medium, routine ventral hernia cohort was limited to CDC class I wounds, VHWG hernia grades I and II, and hernia defects <5 cm. The study group was comprised of P4HB meshes; the comparator group was an aggregate of PP meshes. Clinical outcomes were assessed at 30 days. Results There was no significant difference in early wound morbidity, readmission, or reoperation between the P4HB and PP cohorts. A small number of patients experienced SSO, with ≤4% requiring procedural intervention. None of the patients (0% in all cases) experienced skin/soft tissue necrosis, infected seroma, infected hematoma, exposed/contaminated/infected mesh, enterocutaneous fistula, graft failure, or pain requiring intervention at 30-days. However, P4HB was associated with significantly greater operative time, length of stay, and use of myofascial release compared to PP (p < 0.05 in all cases). Conclusions Short-term clinical outcomes associated with resorbable P4HB mesh are comparable to permanent synthetic PP mesh in umbilical and small to medium, routine ventral hernia repairs, despite significant differences in operative time and length of stay. Longer-term follow-up is needed to expand on the clinical relevance of these short-term findings.

The impact of comorbidities on postoperative outcomes of ventral hernia repair: the patients' perspective. Hernia 2023:10.1007/s10029-023-02826-8. [PMID: 37410195 DOI: 10.1007/s10029-023-02826-8] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/18/2023] [Accepted: 06/15/2023] [Indexed: 07/07/2023]
Abstract
INTRODUCTION Ventral hernia repair (VHR) outcomes can be adversely affected by modifiable patient co-morbidities, such as diabetes, obesity, and smoking. Although this concept is well accepted among surgeons, the extent to which patients understand the significance of their co-morbidities is unknown, and a few studies have sought to determine patient perspectives regarding the impact of their modifiable co-morbidities on their post-operative outcomes. We attempted to determine how accurately patients predict their surgical outcomes after VHR compared to a surgical risk calculator while considering their modifiable co-morbidities. METHODS This is a prospective, single-center, survey-based study evaluating patients' perceptions of how their modifiable risk factors affect outcomes after elective ventral hernia repair. Pre-operatively, after surgeon counseling, patients predicted the percentage of impact that they believed their modifiable co-morbidities (diabetes, obesity, and smoking) had on 30-day surgical site infections (SSI) and hospital readmissions. Their predictions were compared to the Outcomes Reporting App for CLinicians and Patient Engagement (ORACLE) surgical risk calculator. Results were analyzed using demographic information. RESULTS 222 surveys were administered and 157 were included in the analysis after excluding for incomplete data. 21% had diabetes, 85% were either overweight with body mass index (BMI) 25-29.9 or obese (BMI ≥ 30), and 22% were smokers. The overall mean SSI rate was 10.8%, SSOPI rate was 12.7%, and 30-day readmission rate was 10.2%. ORACLE predictions correlated with observed SSI rates (OR 1.31, 95% CI 1.12-1.54, p < 0.001), but patient predictions did not (OR 1.00, 95% CI 0.98-1.03, p = 0.868). The correlation between patient predictions and ORACLE calculations was weak ([Formula: see text] = 0.17). Patient predictions were on average 10.1 ± 18.0% different than ORACLE, and 65% overestimated their SSI probability. Similarly, ORACLE predictions correlated with observed 30-day readmission rates (OR 1.10, 95% CI 1.00-1.21, p = 0.0459), but patient predictions did not (OR 1.00, 95% CI 0.975-1.03, p = 0.784). The correlation between patient predictions and ORACLE calculations for readmissions was weak ([Formula: see text] = 0.27). Patient predictions were on average 2.4 ± 14.6% different than ORACLE, and 56% underestimated their readmission probability. Additionally, a substantial proportion of the cohort believed that they had a 0% risk of SSI (28%) and a 0% risk of readmission (43%). Education, income and healthcare employment did not affect the accuracy of patient predictions. CONCLUSIONS Despite surgeon counseling, patients do not accurately estimate their risks after VHR when compared to ORACLE. Most patients overestimate their SSI risk and underestimate their 30-day readmission risk. Furthermore, several patients believed that they had a 0% risk of SSI and readmission. These findings persisted regardless of level of education, income level, or healthcare employment. Additional attention should be directed toward setting expectations prior to surgery and using applications such as ORACLE to assist in this process.

Application of Component Separation and Short-Term Outcomes in Ventral Hernia Repairs. J Surg Res 2023; 282:1-8.

Abstract
INTRODUCTION Component separation (CS) techniques have evolved in recent years. How surgeons apply the various CS techniques, anterior component separation (aCS) versus posterior component separation (pCS), by patient and hernia-specific factors remain unknown in the general population. Improving the quality of ventral hernia repair (VHR) on a large scale requires an understanding of current practice variations and how these variations ultimately affect patient care. In this study, we examine the application of CS techniques and the associated short-term outcomes while taking into consideration patient and hernia-specific factors. METHODS We retrospectively reviewed a clinically rich statewide hernia registry, the Michigan Surgical Quality Collaborative Hernia Registry, of persons older than 18 y who underwent VHR between January 2020 and July 2021. The exposure of interest was the use of CS. Our primary outcome was a composite end point of 30-d adverse events including any complication, emergency department visit, readmission, and reoperation. Our secondary outcome was surgical site infection (SSI). Multivariable logistic regression examined the association of CS use, 30-d adverse events, and SSI with patient-, hernia-, and operative-specific variables. We performed a sensitivity analysis evaluating for differences in application and outcomes of the posterior and aCS techniques. RESULTS A total of 1319 patients underwent VHR, with a median age (interquartile range) of 55 y (22), 641 (49%) female patients, and a median body mass index of 32 (9) kg/m2. CS was used in 138 (11%) patients, of which 101 (73%) were pCS and 37 (27%) were aCS. Compared to patients without CS, patients undergoing a CS had larger median hernia widths (2.5 cm (range 0.01-23 cm) versus 8 cm (1-30 cm), P < 0.001). Of the CS cases, 49 (36%) performed in hernias less than 6 cm in size. Following multivariate regression, factors independently associated with the use of a CS were diabetes (odds ratio [OR]: 2.00, 95% confidence interval [CI]: 1.19-3.36), previous hernia repair (OR: 1.88, 95% CI: 1.20-2.96), hernia width (OR: 1.28, 95% CI: 1.22-1.34), and an open approach (OR: 3.83, 95% CI: 2.24-6.53). Compared to patients not having a CS, use of a CS was associated with increased odds of 30-d adverse events (OR: 1.88 95% CI: 1.13-3.12) but was not associated with SSI (OR: 1.95, 95% CI: 0.74-4.63). Regression analysis demonstrated no differences in 30-d adverse events or SSI between the pCS and aCS techniques. CONCLUSIONS This is the first population-level report of patients undergoing VHR with concurrent posterior or aCS. These data suggest wide variation in the application of CS in VHR and raises a concern for potential overutilization in smaller hernias. Continued analysis of CS application and the associated outcomes, specifically recurrence, is necessary and underway.

Abstract
Introduction: The admission of patients on weekends in multiple health centers has been associated with poorer outcomes relative to care provided during regular weekday hours. This study aimed to assess and compare the health outcomes of patients discharged on weekends and weekdays after undergoing surgery in a tertiary hospital in Taif, Saudi Arabia. Materials and methods: The data of patients were collected from hospital records in a retrospective manner, and the outcomes were assessed after discharge. Patients discharged on Friday and Saturday were considered weekend discharges, and those discharged on other days were considered weekday discharges. Data related to readmission and emergency department (ED) visits included the primary diagnosis, number of days post-primary discharge, length of stay, chief complaint, and the number of ED visits. A logistic regression model was done to assess the predictive factor for 30-readmission after surgery. Results: The frequency of discharge over the weekend was 9.1%. About 6.5% and 7.3% were found to have 30-day readmission and 30-day ED visits, respectively. A statistically significant association was not observed between weekend discharge and the development of postoperative complications (p>0.05). A multinomial logistic regression showed that patients who had emergency admission, postoperative complications, and the presence of cancer were found to be independently associated with 30-day readmission after discharge (P<0.05). Conclusion: Proactive strategies to reduce costly readmissions after surgery can be designed once the high-risk patient subset is identified.

Preoperative anemia is a risk factor for poor perioperative outcomes in ventral hernia repair. Hernia 2022; 26:1599-1604. [PMID: 35175459 DOI: 10.1007/s10029-022-02572-3] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/29/2021] [Accepted: 01/23/2022] [Indexed: 11/04/2022]
Abstract
PURPOSE Ventral hernia repairs (VHR) are among the most commonly performed operations by general surgeons. Despite advances in technology there remains high complication and readmission rates. Preoperative anemia has been linked to poor outcomes and readmission across several surgical procedures, however the link to ventral hernia repair outcomes is limited. METHODS Utilizing the American College of Surgeons National Safety and Quality Improvement Project (NSQIP) database for years 2016-2018, a total of 115,000 patients met inclusion criteria. Using propensity matching we matched two groups of patients who underwent VHR: (1) those with preoperative anemia and (2) those with normal hemoglobin levels. Anemia criteria was set forth by the World Health Organization (WHO). RESULTS Univariate analysis did demonstrate statistical significance in post-operative outcomes percentage of serious surgical site infection, poor renal outcomes, transfusion, and unplanned remission in those with preoperative anemia who underwent VHR. In a multivariate analysis, patients who underwent ventral hernia repair with pre-operative anemia had significantly greater odds of unplanned readmission (odds ratio 1.35, 95% confidence interval 1.16-1.57) and serious surgical site infection (odds ratio 1.35, 95% confidence interval 1.04-1.74) independent of known risk factors such as smoking, diabetes and obesity. CONCLUSIONS Preoperative anemia is a risk factor for poor postoperative outcomes in those undergoing ventral hernia repair and should be considered when evaluating a patient for repair.

[PMID: 34816306 DOI: 10.1007/s00464-021-08878-0] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/03/2021] [Accepted: 11/14/2021] [Indexed: 11/25/2022]
Abstract
BACKGROUND Socioeconomic disparities have been associated with outcomes in many medical conditions. The association of socioeconomic status (SES) with readmissions after ventral and inguinal hernia repair has not been well studied on a national level. This study aims to evaluate the association of SES with readmission as a significant outcome in patients undergoing ventral and inguinal hernia repair. METHODS A retrospective cohort study was performed evaluating patients undergoing ventral hernia and inguinal hernia repair with 1:1 propensity score matching using the Nationwide Readmissions Database (2016-2017). Both 30- and 90-day readmissions were examined. After matching, a multivariate logistic regression analysis was performed using confounding variables including hospital setting, comorbidities, urgency of repair, sociodemographic status, and payer. Likelihood of readmission was reported in odds ratio form. RESULTS Readmission rates were 11.56% (24,323 out of 210,381) and 17.94% (30,893 out of 172,210) for 30- and 90-day readmissions, respectively. Patients with Medicaid and in the lower income quartile were more likely to present in an emergent fashion for hernia repair. After matching, a multivariate logistic regression analysis showed socioeconomic status (OR 1.250 and 1.229) was a statistically significant independent predictor of readmission at 30 and 90 days, respectively. Inversely, factors associated with the least likely chance of readmission were a laparoscopic approach (OR 0.646 and 0.641), elective admission (OR 0.824 and 0.779), and care in a teaching hospital (OR 0.784 and 0.798). CONCLUSION SES is an independent predictor of readmission at 30 and 90 days following open and laparoscopic ventral and inguinal hernia repair. Patients with a lower socioeconomic status were more likely to undergo hernia repair in the emergent setting. Efforts toward mitigating SES disparities by potentially promoting MIS techniques, enhancing access to elective cases, and systematic approaches to perioperative care for this disadvantaged population can potentially enhance overall hernia outcomes.

Abstract
BACKGROUND Enhanced recovery after surgery (ERAS) are evidence-based protocols associated with improved patient outcomes. The use of ERAS pathways is well documented in various surgical specialties. The aim of this systematic review and meta-analysis was to examine the efficacy of ERAS protocols in patients undergoing abdominal wall reconstruction (AWR). METHODS This systematic review and meta-analysis were reported according to PRISMA and MOOSE guidelines. The databases PubMed, EMBASE, CINAHL, Web of Science and Cochrane Library were searched for original studies comparing ERAS with standard care in patients undergoing AWR. The primary outcome was length of stay (LOS) and secondary outcomes were readmission and surgical site infection (SSI) and/or surgical site occurrences (SSO). RESULTS Five studies were included in the meta-analysis. All were retrospective cohort studies including 453 patients treated according to ERAS protocols, and 494 patients treated according to standard care. The meta-analysis demonstrated that patients undergoing AWR managed with ERAS had a mean 0.89 days reduction in LOS compared with patients treated with standard care (95% CI - 1.70 to - 0.07 days, p = 0.03). There was no statistically significant difference in readmission rate (OR 1.00, 95% CI 0.53 to 1.87, p = 1.00) or SSI/SSO (OR 1.19, 95% CI 0.67 to 2.11, p = 0.56) between groups. CONCLUSIONS The use of ERAS in patients undergoing AWR was found to significantly reduce LOS without increasing the readmission rate or SSI/SSO. Based on the existing literature, ERAS protocols should be implemented for patients undergoing AWR.

Abstract
INTRODUCTION The evaluation of the re-admission rate within 30 days of inguinal hernia repair represents a patient management quality indicator. The goal of our study was to evaluate the re-admission rate at 30 days after inguinal hernia repair and identify the risk factors for re-admission. METHODS Based on a prospective national registry, patient data were collected during two years. The number of and reasons for re-admissions were compiled. RESULTS A total of 5126 patients, mean age 61 years, underwent inguinal hernia repair. Ambulatory surgery was performed in 4013 (78%) patients. Failed ambulatory surgery was recorded for 100 (2%) patients. Thirty-three (0.64%) patients were re-admitted within 30 days following surgery for 34 various reasons. The re-admission rate after ambulatory surgery was 0.5%. Half of patients re-admitted presented with a severe complication that required re-intervention. In multivariable analysis, emergency hernia repair (OR 4.899 [1.309-18.327]; P=0.01) and prolonged duration of operation (OR 1.023 [1.009-1.037]; P=0.001) were identified as independent risk factors for re-admission within 30 days after surgery. CONCLUSION Within this prospective national cohort, the overall re-admission rate after inguinal hernia repair was 0.64%, slightly less among the patients undergoing ambulatory surgery. Half of re-admitted patients required surgical re-operation. Emergency hernia repair and prolonged duration of operation were risk factors for re-admission.

Abstract
BACKGROUND Hospital readmissions are recognized as indicators of poor healthcare services which further increase patient morbidity. The aim of this study is to analyze predicting factors for the 30-day and 90-day readmissions after a complex abdominal wall reconstruction (CAWR). METHODS A pooled analysis of the prospective study and retrospective database patients undergoing CAWR with acellular porcine dermis from 2012 to 2019 was carried out. Independent t test for continuous variables and Chi-square and Fischer's exact tests for categorical variables were used. A multivariable logistic regression model and linear regression analysis were used to analyze the independent predictors of 30-day and 90-day readmissions. RESULTS A total of 232 patients underwent CAWR, and the readmission rate (RR) was 16.8% (n = 40). The 30-day and 90-day RR was 11.3% (n = 23) and 13.3% (n = 33), respectively. There were no statistical differences in age, frailty, and gender distribution between the two groups. There was no difference in ASA score, type of component separation, ventral hernia working group class, size of the biological mesh, placement of mesh, and intestinal resection rate. The Clavien-Dindo complications and mean comprehensive complication index (CCI) were higher in the readmission group as compared to no readmission group (p < 0.01). Readmitted patients had higher surgical site infections (p < 0.01) and wound necrosis (p = 0.01). Higher CCI, past or concomitant pelvic surgery, and the presence of enterocutaneous fistula were independent predictors of earlier days to readmission. CONCLUSION Surgical site occurrences were associated with 30-day and 90-day readmissions after CAWR, while the presence of ascites and dialysis was associated with 90-day readmissions.

Abstract
BACKGROUND Preoperative opioid use is a risk factor for complications after some surgical procedures. The purpose of this study was to investigate the influence of preoperative opiates on outcomes after ventral hernia repair. METHODS With institutional review board approval, we conducted a retrospective review of consecutive ventral hernia repair cases during a 4-y period. RESULTS A striking 48% of the total 234 patients met criteria for preoperative opioid use. Preoperative characteristics and operative details were similar between patient groups (preoperative opioid use versus no preoperative opioid use). Median duration of hospital stay trended toward an increase for opioid users versus nonopioid users (P = .06). Return of bowel function was delayed in opioid users compared with nonopioid users (P = .018). Incidence of superficial surgical site infection was increased among patients who used opioids preoperatively (27% vs 8.3%; P <.001) and remained so after multivariable logistic regression, (adjusted odds ratio 2.9, 95% confidence interval 1.2-6.7; P = .013). CONCLUSION Among patients undergoing ventral hernia repair, those with preoperative opioid use experienced an increased incidence of superficial surgical site infection compared with patients without preoperative opioid use. Further study is needed to understand the relationship between opioid use and surgical site infection after ventral hernia repair.

One-Year Health Care Utilization and Recurrence After Incisional Hernia Repair in the United States: A Population-Based Study Using the Nationwide Readmission Database. J Surg Res 2020; 255:267-276. [PMID: 32570130 DOI: 10.1016/j.jss.2020.03.070] [Citation(s) in RCA: 15] [Impact Index Per Article: 3.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/09/2019] [Revised: 03/15/2020] [Accepted: 03/27/2020] [Indexed: 01/24/2023]
Abstract
BACKGROUND Most data on health care utilization after incisional hernia (IH) repair are limited to 30-days and are not nationally representative. We sought to describe nationwide 1-year readmission burden after IH repair (IHR). METHODS Patients undergoing elective IHR discharged alive were identified using the 2010-2014 Nationwide Readmission Database. Transfers and incomplete follow-up were excluded. Descriptive statistics were used to describe rates of 1-year readmission, IH recurrence, and bowel obstruction. Cox regression allowed identification of factors associated with 1-year readmissions. Generalized linear models were used to estimate predicted mean difference in cumulative costs/year, which allowed estimation of IHR readmission costs/year nationwide. RESULTS Of 15,935 identified patients, 19.35% were readmitted within 1 y. Patients who were readmitted differed by insurance, Charlson index, illness severity, smoking status, disposition, and surgical approach compared with those who were not (P < 0.05). Of readmitted patients, 39.3% returned within 30 d; 50.9% and 25.6% were due to any and infectious complications, respectively; 25.6% presented to a different hospital; 35.4% required reoperation; 5.4% experienced bowel obstruction; and 5% had IHR revision. Factors associated with readmissions included Medicare (hazard ratio [HR] 1.46 [95% confidence interval 1.19-1.8]; P < 0.01) or Medicaid (HR 1.42 [1.12-1.8], P < 0.01); chronic pulmonary disease (1.38 [1.17-1.64], P < 0.01), and anemia (1.36, [1.05-1.75], P = 0.02). Readmitted patients had higher 1-year cumulative costs (predicted mean difference $12,190 [95% CI: 10,941-13,438]; P < 0.01). Nationwide cost related to readmissions totaled $90,196,248/y. CONCLUSIONS One-year readmissions after IHR are prevalent and most commonly due to postoperative complications, especially infections. One-third of readmitted patients require a subsequent operation, and 5% experience IH recurrence, intensifying the burden to patients and on the health care system.

Abstract
PURPOSE Lower socioeconomic status has been shown to be predictive of poorer surgical outcomes in ventral hernia repair. Recently, safety-net hospitals have been attempting to address these disparities to improve the care of patients of lower socioeconomic status. METHODS A query of all patients undergoing ventral hernia repair at our institution between 2010 and 2019 was completed (n = 580). Patients not from identifiable New Jersey ZIP-codes were excluded (n = 572). ZIP codes were assigned quartiles based off socioeconomic variables including median household income, percent below poverty line, and high school graduation rate. Patients were then assigned to socioeconomic status quartiles based off their residential ZIP-code. Outcomes of ventral hernia surgery were compared across ZIP-code quartiles. Logistic regression was used to analyze predictors of poor outcomes. RESULTS Patients from lower socioeconomic brackets were more likely to be younger (p < 0.001), female (p = 0.014), black (p < 0.001), and/or Hispanic (p = 0.003). Most notably, outcomes of ventral hernia were not significantly different between patients of different socioeconomic status ZIP-code quartiles. The risk of any post-operative morbidity was higher for longer procedures (p < 0.001) and for hernia repairs being done with other procedures (p < 0.001). Risk of prolonged length of stay and related 30-day readmission was higher with longer procedures (p < 0.001 and p = 0.003, respectively). CONCLUSION We found that outcomes of ventral hernia repair at a safety-net hospital were unaffected by socioeconomic status. This supports the important role that safety-net institutions play in providing quality care to their vulnerable populations. Future studies at other safety-net hospitals should be done to further assess the updated impact of socioeconomic status on ventral hernia outcomes.

Abstract
BACKGROUND The safety and effectiveness of expectant management (e.g., watchful waiting or initially managing non-operatively) for patients with a ventral hernia is unknown. We report our 3-year results of a prospective cohort of patients with ventral hernias who underwent expectant management. METHODS A hernia clinic at an academic safety-net hospital was used to recruit patients. Any patient undergoing expectant management with symptoms and high-risk comorbidities, as determined by a surgeon based on institutional criteria, would be included in the study. Patients unlikely to complete follow-up assessments were excluded from the study. Patient-reported outcomes were collected by phone and mailed surveys. A modified activities assessment scale normalized to a 1-100 scale was used to measure results. The rate of operative repair was the primary outcome, while secondary outcomes include rate of emergency room (ER) visits and both emergent and elective hernia repairs. RESULTS Among 128 patients initially enrolled, 84 (65.6%) completed the follow-up at a median (interquartile range) of 34.1 (31, 36.2) months. Overall, 28 (33.3%) patients visited the ER at least once because of their hernia and 31 (36.9%) patients underwent operative management. Seven patients (8.3%) required emergent operative repair. There was no significant change in quality of life for those managed non-operatively; however, substantial improvements in quality of life were observed for patients who underwent operative management. CONCLUSIONS Expectant management is an effective strategy for patients with ventral hernias and significant comorbid medical conditions. Since the short-term risk of needing emergency hernia repair is moderate, there could be a safe period of time for preoperative optimization and risk-reduction for patients deemed high risk.

Abstract
IMPORTANCE Ventral and incisional hernia repair (VIHR) is an extremely common operation, after which complications are also fairly common. A number of preoperative risk factors are known to contribute to increased complications after surgical repair; however, the individual relative association of these risk factors with adverse outcomes and increased spending is unclear. Quantifying the association of individual risk factors may help surgeons implement targeted surgical optimization, improve outcomes, and reduce spending. OBJECTIVE To identify the attributable association of modifiable risk factors for adverse outcomes after VIHR on outcomes and episode-of-care payments. DESIGN, SETTING, AND PARTICIPANTS This cross-sectional study was performed using a population-based sample of adult patients and episode spending data from January 1, 2012, to December 31, 2018, from a statewide multipayer registry. A multilevel mixed-effects logistic regression model was used to examine the contribution of patient-specific risk factors to adverse outcomes. Attributable risk and population attributable risk fraction were calculated to estimate the additional spending attributable to individual risk factors. Data were analyzed from April 2018 to September 2018. MAIN OUTCOMES AND MEASURES Any complications, serious complication, discharge not to home, 30-day emergency department utilization, and 30-day readmission. Episode-of-care spending was calculated for these outcomes. RESULTS This study included 22 664 patients (median [interquartile range] age, 55 [44-64] years; 10 496 [46.3%] women) undergoing VIHR with identified significant preoperative risk factors. Fourth-quartile body mass index (BMI), calculated as weight in kilograms divided by height in meters squared and defined as a mean (SD) BMI of 43 (6), was associated with increased risk of any complication (odds ratio [OR], 1.64; 95% CI, 1.30-2.06; P < .001) and serious complication (OR, 1.67; 95% CI, 1.22-2.31; P = .002). Insulin-dependent diabetes was associated with increased risk of any complication (OR, 1.34; 95% CI, 1.03-1.73; P = .03), serious complication (OR, 1.51; 95% CI, 1.08-2.12; P = .02), discharge not to home (OR, 1.49; 95% CI, 1.12-1.98; P = .005), and 30-day readmission (OR, 1.68; 95% CI, 1.32-2.14; P < .001). Median (interquartile range) additional episode spending for any complication was $9934 ($9224-$11 851), of which $1304 ($1208-$1552) was attributable to fourth-quartile BMI. Median (interquartile range) additional episode spending for a serious complication was $26 648 ($20 632-$33 166), of which $3638 ($2827-$4544) was attributable to fourth-quartile BMI, $650 ($495-$796) was attributable to insulin-dependent diabetes, and $567 ($433-$696) was attributable to unhealthy alcohol use. CONCLUSIONS AND RELEVANCE In this cross-sectional study, modifiable risk factors, such as obesity, insulin-dependent diabetes, and unhealthy alcohol use, were associated with adverse outcomes after VIHR. These factors were significantly associated with increased health care spending; therefore, preoperative optimization may improve outcomes and decrease episode-of-care costs.

Abstract
PURPOSE The purpose of this study was to determine if there is an increased postoperative complication rate in orthognathic surgery during the first academic quarter (Q1) (July to September). MATERIALS AND METHODS The American College of Surgeons National Surgical Quality Improvement Program database was accessed to identify cases with Current Procedural Terminology codes pertaining to orthognathic procedures from 2008 to 2017. Procedures were separated into 2 groups based on time in the academic year: Q1 (July to September) versus remaining quarters (RQ). The inclusion criteria were Current Procedural Terminology codes representing operations resulting in movement of the dentate portion of the jaws and age of 18 years or older. Patient demographic characteristics and perioperative complications were compared between the groups. Descriptive statistics, Fisher exact tests, and χ2 tests were executed. RESULTS The Q1 cohort included 877 cases, and the RQ cohort included 2,062 cases. The average age of patients was 47.0 ± 19.5 years in Q1 versus 47.2 ± 19.4 years in RQ. The most frequent complications were blood transfusion (11.97% in Q1 vs 12.57% in RQ, P = .64), reoperation (8.67% in Q1 vs 8.84% in RQ, P = .87), and combined superficial and deep-space infection (5.02% in Q1 vs 5.76% in RQ, P = .51). Medical complications involving other organ systems were rare (<1%). Analyses showed no significance between complication rate and time of year. CONCLUSIONS The results of this study indicate that there is no association between time of year and complication rates after orthognathic surgery. Additional investigations could be useful in shining light on this topic as it pertains to the training of future surgeons.

Enhanced recovery after surgical repair of incisional hernias. Hernia 2019; 24:3-8. [PMID: 31177341 DOI: 10.1007/s10029-019-01992-y] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/11/2019] [Accepted: 06/02/2019] [Indexed: 12/25/2022]
Abstract
AIM Enhanced recovery programmes (ERPs) were developed to improve the patient's post-operative comfort and reduce post-operative morbidity after several types of major surgery including the incisional hernia repair. The aim of this review was to describe the features of ERPs in the setting for incisional hernia repair. METHODS The literature review was conducted until March 2019, but retrieved very few papers (n = 4) on this topic. All studies were retrospective. RESULTS Setting and comorbidities of incisional hernia patients are of such importance in many cases that prehabilitation (including tobacco use cessation, management of obesity, diabetes or malnutrition) should play a greater role compared with other specialties. The other peri-operative measures are similar to other specialties but their implementation was very heterogeneous in the published studies. CONCLUSIONS Like in other surgeries, ERPs were feasible and probably efficient to improve the post-operative course of incisional hernia patients. But the level of evidence remains low.

Abstract
IMPORTANCE Ambulatory surgery in geriatric populations is increasingly prevalent. Prior studies have demonstrated the association between frailty and readmissions in the inpatient setting. However, few data exist regarding the association between frailty and readmissions after outpatient procedures. OBJECTIVE To examine the association between frailty and 30-day unplanned readmissions after elective outpatient surgical procedures as well as the potential mediation of surgical complications. DESIGN, SETTING, AND PARTICIPANTS In this retrospective cohort study of elective outpatient procedures from 2012 and 2013 in the National Surgical Quality Improvement Program (NSQIP) database, 417 840 patients who underwent elective outpatient procedures were stratified into cohorts of individuals with a length of stay (LOS) of 0 days (LOS = 0) and those with a LOS of 1 or more days (LOS ≥ 1). Statistical analysis was performed from June 1, 2018, to March 31, 2019. EXPOSURE Frailty, as measured by the Risk Analysis Index. MAIN OUTCOMES AND MEASURES The main outcome was 30-day unplanned readmission. RESULTS Of the 417 840 patients in this study, 59.2% were women and unplanned readmission occurred in 2.3% of the cohort overall (LOS = 0, 2.0%; LOS ≥ 1, 3.4%). Frail patients (mean [SD] age, 64.9 [15.5] years) were more likely than nonfrail patients (mean [SD] age, 35.0 [15.8] years) to have an unplanned readmission in both LOS cohorts (LOS = 0, 8.3% vs 1.9%; LOS ≥ 1, 8.5% vs 3.2%; P < .001). Frail patients were also more likely than nonfrail patients to experience complications in both cohorts (LOS = 0, 6.9% vs 2.5%; LOS ≥ 1, 9.8% vs 4.6%; P < .001). In multivariate analysis, frailty doubled the risk of unplanned readmission (LOS = 0: adjusted relative risk [RR], 2.1; 95% CI, 2.0-2.3; LOS ≥ 1: adjusted RR, 1.8; 95% CI, 1.6-2.1). Complications occurred in 3.1% of the entire cohort, and frailty was associated with increased risk of complications (unadjusted RR, 2.6; 95% CI, 2.4-2.8). Mediation analysis confirmed that complications are a significant mediator in the association between frailty and readmissions; however, it also indicated that the association of frailty with readmission was only partially mediated by complications (LOS = 0, 22.8%; LOS ≥ 1, 29.3%). CONCLUSIONS AND RELEVANCE These findings suggest that frailty is a significant risk factor for unplanned readmission after elective outpatient surgery both independently and when partially mediated through increased complications. Screening for frailty might inform the development of interventions to decrease unplanned readmissions, including those for outpatient procedures.

Effect of an Evidence-based Inpatient Tobacco Dependence Treatment Service on 1-Year Postdischarge Health Care Costs. Med Care 2019; 56:883-889. [PMID: 30130271 PMCID: PMC6136961 DOI: 10.1097/mlr.0000000000000979] [Citation(s) in RCA: 13] [Impact Index Per Article: 2.6] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Indexed: 11/18/2022]
Abstract
Background: In 2014, the Medical University of South Carolina (MUSC) implemented a Tobacco Dependence Treatment Service (TDTS) consistent with the Joint Commission (JC) standards recommending that hospitals screen patients for smoking, provide cessation support, and follow-up contact for relapse prevention within 1 month of discharge. We previously demonstrated that patients exposed to the MUSC TDTS were approximately half as likely to be smoking one month after discharge and 23% less likely to have a 30-day hospital readmission. This paper examines whether exposure to the TDTS influenced downstream health care charges 12 months after patients were discharged from the hospital. Methods: Data from MUSC’s electronic health records, the TDTS, and statewide health care utilization datasets (eg, hospitalization, emergency department, and ambulatory surgery visits) were linked to assess how exposure to the MUSC TDTS impacted health care charges. Total health care charges were compared for patients with and without TDTS exposure. To reduce potential TDTS exposure selection bias, propensity score weighting was used to balance baseline characteristics between groups. The cost of delivering the MUSC TDTS intervention was calculated, along with cost per smoker. Results: The overall adjusted mean health care charges for smokers exposed to the TDTS were $7299 lower than for those who did not receive TDTS services (P=0.047). The TDTS cost per smoker was modest by comparison at $34.21 per smoker eligible for the service. Discussion: Results suggest that implementation of a TDTS consistent with JC standards for smoking cessation can be affordably implemented and yield substantial health care savings that would benefit patients, hospitals, and insurers.

Abstract
BACKGROUND Readmissions represent a substantial burden to the health care system. Risk factors for 30-day readmission after adrenalectomy were examined. METHODS Patients who underwent adrenalectomy were selected from the American College of Surgeons National Surgical Quality Improvement Program database from 2011 to 2015. RESULTS Among 4,221 patients who underwent adrenalectomy, 216 (5.1%) were readmitted. On multivariate analysis, pre-operative predictive factors associated with readmission were American Society of Anesthesiologists classification (odds ratio [OR] 1.4, confidence interval [CI] 1.1-1.8), disseminated cancer (OR 1.6, CI 1.1-2.5), and adrenal injury (OR 10.9, CI 1.8-68.9). Elective procedures had fewer readmissions (OR 0.50, CI 0.33-0.76). and procedures with greater relative value units had greater readmission rates (OR 1.01, CI 1.004-1.02). An open adrenalectomy (21% of patients) had a higher rate of readmission than a laparoscopic approach (8.0% vs 4.3%, OR 1.5, CI 1.1-2.0). Postoperative risk factors affecting readmission included reoperations (OR 3.2, CI 1.3-8.0), wound complications (OR 6.6, CI 3.8-11.7), systemic infection (OR 6.5, CI 3.9-10.7), renal complications (OR 7.1, CI 2.6-19.2), venous thrombotic events (OR 11.3, CI 5.6-22.6), and discharge to home (OR 0.40, CI 0.22-0.73). CONCLUSION Encouraging the appropriate use of laparoscopic adrenalectomy, preventing venous thrombotic events and surgical infections, and improving early post-operative follow-up in high-risk patients may decrease readmissions.

Abstract
Thirty-day readmission after surgery has been proposed as a quality-of-care indicator. We explored the effect of postoperative rehabilitation on readmission risk after groin hernia repair. We used the French National Discharge Database to identify all index hospitalizations for groin hernia repair in 2011. Readmissions within 30 days of discharge were clinically classified in terms of their relationship to the index stay. We used logistic regression to adjust the risk of readmission for patient, procedure and hospital factors. Among 122,952 index hospitalizations for inguinal hernia repair, 3,357 (2.7%) related 30-day readmissions were recorded. Reiterated analyses indicated that readmission risk was consistently associated with patient complexity: age (per year after 60 years, OR 1.03, 95% CI 1.02-1.03, P < 0.001), hospitalization within the previous year (OR 1.56, 95% CI 1.44-1.69, P < 0.001), and increasing severity and combination of co-morbidities. Postoperative rehabilitation was identified as a protective factor (OR 0.56, 95% CI 0.46-0.69, P < 0.001). Older patients and those with greater comorbidity are at elevated risk of readmission after inguinal hernia repair. Postoperative rehabilitation may reduce this risk. Further studies are warranted to confirm the protective effect of postoperative rehabilitation.

Abstract
This article reviews the literature that supports routine expectations for smoking cessation; weight loss; diabetic, nutritional, or metabolic optimization; and decolonization techniques before ventral hernia repair. These methods diminish postoperative complications. In an era of value-centric care, an upfront investment in patient optimization can improve the quality of the repair by reducing wound morbidity and hernia recurrence, naturally translating to a reduction in cost. The adoption of these practices and further study aimed at identifying other effective optimization techniques are encouraged.

Abstract
INTRODUCTION Smoking is a risk factor for hospitalization and interferes with patient care due to its effects on pulmonary function, wound healing, and interference with treatments and medications. Although benefits of stopping smoking are well-established, few hospitals provide tobacco dependence treatment services (TDTS) due to cost, lack of mandatory tobacco cessation standards and lack of evidence demonstrating clinical and financial benefits to hospitals and insurers for providing services. METHODS This study explored the effect of an inpatient TDTS on 30-, 90-, and 180-day hospital readmissions. To carry out this work, 3 secondary datasets were linked, which included clinical electronic health record data, tobacco cessation program data, and statewide health care utilization data. Odds ratios (ORs) were calculated using inverse propensity score-weighted logistic regression models, with program exposure as the primary independent variable and 30 (90 and 180)-day readmission rates as the dependent variable, and adjustment for putative covariates. RESULTS Odds of readmission were compared for patients who did and did not receive TDTS. At 30 days postdischarge, smokers exposed to the TDTS had a lower odds of readmission (OR=0.77, P=0.031). At 90 and 180 days, odds of readmission remained lower in the TDTS group (ORs=0.87 and 0.86, respectively), but were not statistically significant. DISCUSSION Findings from the current study, which are supported by prior studies, provide evidence that delivery of TDTS is a strategy that may help to reduce hospital readmissions.

Abstract
BACKGROUND Hospitals usually reduce staffing levels and services over weekends. This raises the question of whether patients discharged over a weekend may be inadequately prepared and possibly at higher risk of adverse events post-discharge. OBJECTIVES To assess the outcomes of common general surgery procedures for patients discharged over weekends, and to identify the key predictors of early readmission. DESIGN Retrospective cohort study. SETTING A tertiary care center. PATIENTS AND METHODS Patients discharged from general surgery services during the one-year period between January and December 2016 after cholecystectomy, appendectomy, or hernia repairs were included. Patient demographic information, comorbidities, and complications as well as admission and follow-up details were collected from electronic medical records. MAIN OUTCOME MEASURES Outcomes following weekend discharge, and the predictors of early readmission. SAMPLE SIZE 743 patients. RESULTS The operations performed: 361 patients (48.6%) underwent a cholecystectomy, 288 (38.8%) an appendectomy, and 94 (12.6%) hernia repairs. A significantly lower number of patients were discharged over the weekend (n=125) compared to those discharged on weekdays (n=618). Patients discharged during the weekend were younger, less likely to have chronic diseases, and had a significantly shorter average length of stay (LOS) (median 2 days, IQR: 1, 4 vs. median 3 days, IQR: 1, 5, P=.002). Overall, the 30-day readmission rate was 3.2% (n=24), and weekend discharge (OR=2.25, 95% CI 0.52-9.70) or any other variable did not predict readmission in 30 days. However, 14-day post-discharge follow-up visits were significantly lower in the weekend discharge subgroup (83.1% vs. 91.2%, P=.006). CONCLUSION Weekend discharge was not associated with higher readmission rates. Physicians may consider discharging post-operative patients over a weekend without an increased risk to the patient. Day of discharge, length of stay and increased patient age are not predictors of early readmission. LIMITATIONS Single-center study and retrospective. CONFLICT OF INTEREST None.

Abstract
Ventral hernia disease is becoming increasingly prevalent and complex. Subspecialisation for patients with challenging conditions requiring surgery has been shown to improve postoperative outcomes. Worldwide, there is an emergence of specialist hernia centres using new and innovative techniques to repair large and complicated ventral hernias. After a national meeting of hernia experts, we present an algorithm to be used as a national triage system for patients with ventral hernias, with the aim of ensuring that patients are operated on by the most appropriate surgeon. Evidence-based clinical risk factors and ventral hernia parameters are used for risk stratification and patient triage. We hope that this algorithm will guide future ventral hernia management in the UK.

Abstract
BACKGROUND Open ventral hernia repair (VHR) is often performed in conjunction with other abdominal procedures. Clinical outcomes and financial implications of VHR are becoming better understood; however, financial implications of concomitant VHR during other abdominal procedures are unknown. This study aimed to evaluate the financial implications of adding VHR to open abdominal procedures. METHODS This IRB-approved study retrospectively reviewed hospital costs to 180-day post-discharge of standalone VHRs, isolated open abdominal surgeries (bowel resection or stoma closure, removal of infected mesh, hysterectomy or oophorectomy, panniculectomy or abdominoplasty, open appendectomy or cholecystectomy), performed at our institution from October 1, 2011 to September 30, 2014. The perioperative risk data were obtained from the local National Surgery Quality Improvement Program (NSQIP) database, and resource utilization data were obtained from the hospital cost accounting system. RESULTS 345 VHRs, 1389 open abdominal procedures as described, and 104 concomitant open abdominal and VHR cases were analyzed. The VHR-only group had lower ASA Class, shorter operative duration, and a higher percentage of hernias repaired via separation of components than the concomitant group (p < 0.001). The median hospital cost for VHR-alone was $12,900 (IQR: $9500-$20,700). There were significant increases to in-hospital costs when VHR was combined with removing an infected mesh (63%) or with bowel resections or stoma closures (0.7%). The addition of VHR did not cause a significant change in 180-day post-discharge costs for any of the procedures. CONCLUSIONS This study noted decreased costs when combining VHR with panniculectomy or abdominoplasty and hysterectomy or oophorectomy. For removal of infected mesh and bowel resection or stoma closure, waiting, when feasible, is recommended. Given the impending changes in financial reimbursements in healthcare in the United States, it is prudent that future studies evaluate further the clinical and fiscal benefit of concomitant procedures.

Abstract
The present review assessed the evidence on risk factors for the occurrence of adverse health outcomes after discharge (i.e. unplanned readmission or adverse drug event after discharge) that are potentially modifiable by clinical pharmacist interventions. The findings were compared with patient characteristics reported in guidelines that supposedly indicate a high risk of drug-related problems. First, guidelines and risk assessment tools were searched for patient characteristics indicating a high risk of drug-related problems. Second, a systematic PubMed search was conducted to identify risk factors significantly associated with adverse health outcomes after discharge that are potentially modifiable by a clinical pharmacist intervention. After the PubMed search, 37 studies were included, reporting 16 risk factors. Only seven of 34 patient characteristics mentioned in pertinent guidelines corresponded to one of these risk factors. Diabetes mellitus (n = 11), chronic obstructive lung disease (n = 9), obesity (n = 7), smoking (n = 5) and polypharmacy (n = 5) were the risk factors reported most frequently in the studies. Additionally, single studies also found associations of adverse health outcomes with different drug classes {e.g. warfarin [hazard ratio 1.50; odds ratio (OR) 3.52], furosemide [OR 2.25] or high beta-blocker starting doses [OR 3.10]}. Although several modifiable risk factors were found, many patient characteristics supposedly indicating a high risk of drug-related problems were not part of the assessed risk factors in the context of an increased risk of adverse health outcomes after discharge. Therefore, an obligatory set of modifiable patient characteristics should be created and implemented in future studies investigating the risk for adverse health outcomes after discharge.

Abstract
OBJECTIVE To achieve consensus on the best practices in the management of ventral hernias (VH). BACKGROUND Management patterns for VH are heterogeneous, often with little supporting evidence or correlation with existing evidence. METHODS A systematic review identified the highest level of evidence available for each topic. A panel of expert hernia-surgeons was assembled. Email questionnaires, evidence review, panel discussion, and iterative voting was performed. Consensus was when all experts agreed on a management strategy. RESULTS Experts agreed that complications with VH repair (VHR) increase in obese patients (grade A), current smokers (grade A), and patients with glycosylated hemoglobin (HbA1C) ≥ 6.5% (grade B). Elective VHR was not recommended for patients with BMI ≥ 50 kg/m (grade C), current smokers (grade A), or patients with HbA1C ≥ 8.0% (grade B). Patients with BMI= 30-50 kg/m or HbA1C = 6.5-8.0% require individualized interventions to reduce surgical risk (grade C, grade B). Nonoperative management was considered to have a low-risk of short-term morbidity (grade C). Mesh reinforcement was recommended for repair of hernias ≥ 2 cm (grade A). There were several areas where high-quality data were limited, and no consensus could be reached, including mesh type, component separation technique, and management of complex patients. CONCLUSIONS Although there was consensus, supported by grade A-C evidence, on patient selection, the safety of short-term nonoperative management, and mesh reinforcement, among experts; there was limited evidence and broad variability in practice patterns in all other areas of practice. The lack of strong evidence and expert consensus on these topics has identified gaps in knowledge where there is need of further evidence.

Current Risk Stratification Systems Are Not Generalizable across Surgical Technique in Midline Ventral Hernia Repair. PLASTIC AND RECONSTRUCTIVE SURGERY-GLOBAL OPEN 2017; 5:e1206.

Abstract
Background: Current ventral hernia repair risk estimation tools focus on patient comorbidities with the goal of improving clinical outcomes through improved patient selection. However, their predictive value remains unproven. Methods: Outcomes of patients who underwent midline ventral hernia repair with retrorectus placement of mid-weight soft polypropylene mesh between 2010 and 2015 were retrospectively reviewed and compared with predicted wound-related complication risk from 3 tools in the literature: Carolinas Equation for Determining Associated Risk, the Ventral Hernia Working Group (VHWG) grade, and a modified VHWG grade. Results: A total of 101 patients underwent hernia repair. Mean age was 56 years and mean body mass index was 29 m/kg2 (range, 18–51 m/kg2). We found no significant relationship between the risk estimated by Carolinas Equation for Determining Associated Risk (B = 1.45, P = 0.61) and actual wound-related complications. VHWG grades >1 were not statistically different with regard to rate of wound complication compared with VHWG grade 1 (grade 2: B = 0.05, P = 0.95; grade 3: B = −0.21, P = 0.86; grade 4: B = 2.57, P = 0.10). Modified VHWG grades >1 were not statistically different with regard to rate of wound complication compared with modified VHWG grade 1 (grade 2: B = 0.20, P = 0.80; grade 3: B = 1.03, P = 0.41). Conclusions: Current risk stratification tools overemphasize patient factors, ignoring the importance of technique in minimizing complications and recurrence. We attribute our low complication rate to retrorectus placement of a narrow, macroporous polypropylene mesh with up to 45 suture fixation points for force distribution in contrast to current strategies that employ wide meshes with minimal fixation.

Abstract
BACKGROUND Readmission rates after surgical procedures are viewed as a marker of quality of care and as a driver to improve outcomes in the United Kingdom, they are not remunerated. However, readmissions are not wholly avoidable. The aim of this study was to develop a regional overview of readmissions to determine the proportion that might be avoidable and to examine predictors of readmissions at a unit level. METHODS We undertook a prospective multicenter audit of readmissions following National Health Service funded general surgical procedures in five National Health Service hospitals and three independent sector providers over a 2-wk period. Basic demographic and procedure data were captured. Readmissions to hospitals were identified through acute admissions lists. Reason for readmission was identified, and the readmission data assessed by a senior surgical doctor as to whether it was avoidable. RESULTS We identified 752 operations in the study period with all followed up to 30 d. The overall rate of readmissions was 4.7%, with 40% of these judged as being potentially avoidable. Pain and wound problems accounted for the vast majority of avoidable readmissions. The number of unavoidable readmissions was correlated with the workload of each center (r = 0.63, P = 0.06) and as with the higher (British United Provident Association) complexity of surgery (r = 0.90, P = 0.01). Patient and demographic factors were not associated with readmissions. CONCLUSIONS This prospective audit describes readmission rates after general surgery. Volume and complexity of work are associated with readmission rates. A large proportion of readmissions could be reduced by attention to analgesia and outpatient arrangements for wound management.

Abstract
BACKGROUND The aim of this research was to study the epidemiology, microbiology, prophylaxis, and antibiotic therapy of surgical site infections (SSIs), especially those caused by methicillin-resistant Staphylococcus aureus (MRSA), and identify the risk factors for these infections. In Italy SSIs occur in about 5 % of all surgical procedures. They are predominantly caused by staphylococci, and 30 % of them are diagnosed after discharge. In every surgical specialty there are specific procedures more associated with SSIs. METHODS The authors conducted a systematic review of the literature on SSIs, especially MRSA infections, and used the Delphi method to identify risk factors for these resistant infections. RESULTS Risk factors associated with MRSA SSIs identified by the Delphi method were: patients from long-term care facilities, recent hospitalization (within the preceding 30 days), Charlson score > 5 points, chronic obstructive pulmonary disease and thoracic surgery, antibiotic therapy with beta-lactams (especially cephalosporins and carbapenem) and/or quinolones in the preceding 30 days, age 75 years or older, current duration of hospitalization >16 days, and surgery with prothesis implantation. Protective factors were adequate antibiotic prophylaxis, laparoscopic surgery and the presence of an active, in-hospital surveillance program for the control of infections. MRSA therapy, especially with agents that enable the patient's rapid discharge from hospital is described. CONCLUSION The prevention, identification and treatment of SSIs, especially those caused by MRSA, should be implemented in surgical units in order to improve clinical and economic outcomes.

Abstract
INTRODUCTION Ventral and incisional hernia repair (VIHR) is among the most frequently performed abdominal operations with significant incidence of postoperative complications and readmissions. Payers are targeting increased "value" of care through improved outcomes and reduced costs. Cost data in clinically relevant terms is still rare. This study aims to identify hospital costs associated with clinically relevant factors in order to facilitate strategies by surgeons to enhance the value of VIHR. METHODS An IRB-approved retrospective review of VIHRs performed at the University of Kentucky from April 2009 through September 2013 was conducted. NSQIP clinical data and hospital cost data were matched. Operating room (ORC), total encounter (TEC), and 90-day postdischarge (90PDC) hospital costs were analyzed relative to clinical variables using non-parametric tests. RESULTS In total 385 patients that underwent VIHR during the time period were included in the analyses. Considering all VIHRs, median [interquartile range (IQR)] ORC was $6900 ($5600-$10,000); TEC was $10,700 ($7500-$18,600); and 90PDC was $0 ($0-$800). Compared to all VIHRs, ASA Class ≥ 3 was associated with increased ORC and TEC (p < .001), and 90PDC (p < .01). Preoperative open wound was associated with increased ORC and TEC (p < .001). Numerous operative variables were associated with both increased ORC and TEC. Wound Class > 1 was associated with increased ORC and TEC (p < .001) and 90PDC (p < .01). Inpatient occurrence of any complication was associated with increased TEC and 90PDC (p < .001). CONCLUSIONS ASA Class ≥ 3, Wound Class > 1, open abdominal wound, and postoperative complications significantly increase costs. Although the hospital encounter represents the majority of the cost associated with VIHR, additional costs are incurred during the 90-day postoperative period. An appreciation of global costs is essential in developing alternative payment models for hernia in order to provide the greatest value in hernia care.

Abstract
Background Despite advances in surgical technique, ventral hernia repair (VHR) remains associated with significant postoperative wound complications. Objective A systematic review and meta-analysis was performed to identify whether the application of negative pressure wound therapy to closed incisions (iNPWT) following VHR reduces the risk of postoperative wound complications and hernia recurrence. Methods The PubMed/MEDLINE, EMBASE and SCOPUS databases were searched for studies published through October 2015. Publications that met the following criteria were included: adult patients undergoing VHR; comparison of iNPWT with conventional dressings; and documentation of wound complications and/or hernia recurrence. The methodological quality of included studies was independently assessed using the Methodological Index for Non-Randomized Studies guidelines. Outcomes assessed included surgical site infection (SSI), wound dehiscence, seroma, and hernia recurrence. Meta-analysis was performed to obtain pooled ORs. Results Five retrospective cohort studies including 477 patients undergoing VHR were included in the final analysis. The use of iNPWT decreased SSI (OR 0.33 [95% CI 0.20 to 0.55]; P<0.0001), wound dehiscence (OR 0.21 [95% CI 0.08 to 0.55]; P=0.001) and ventral hernia recurrence (OR 0.24 [95% CI 0.08 to 0.75]; P=0.01). There was no statistically significant difference in the incidence of seroma formation (OR 0.59 [95% CI 0.27 to 1.27]; P=0.18). Conclusion For patients undergoing VHR, current evidence suggests a decreased incidence in wound complications using incisional NPWT compared with conventional dressings.

Abstract
Readmissions pose a significant hardship for patients and constitute a major quality and financial concern for hospitals. We sought to define risk factors associated with hospital readmission after colorectal surgery at a tertiary care hospital. We evaluated readmission among all patients who underwent a colorectal surgical procedure between July 16, 2007 and June 30, 2011. In a cohort of 4879 operative encounters, 492 (10%) were readmitted to the hospital within 30 days of discharge. Procedures with highest readmissions included stoma creation (22%), ileoanal pouch surgery (22%), and total proctocolectomy (30%). In multivariate analysis, the following variables were associated with risk of readmission: postoperative complication, use of anxiolytics, high comorbidity score, patient setting, alcohol use, and stoma creation. Surgeon of record was not associated with readmission. In conclusion, several patient, procedural, and postoperative factors were associated with an increased risk of readmission. Considerably high rates of readmission were noted after stoma creation, ileoanal pouch procedures, and proctocolectomy. Surgeon of record was not associated with risk of read-mission, indicating little value to this metric as a physician-specific indicator of quality.

Abstract
Background Components separation technique emerged several years ago as a novel procedure to improve durability of repair for ventral abdominal hernias. Almost twenty-five years since its initial description, little comprehensive risk adjusted data exists on the morbidity of this procedure. This study is the largest analysis to date of short-term outcomes for these cases. Methods The ACS-NSQIP database identified open ventral or incisional hernia repairs with components separation from 2005 to 2012. A data set of cohorts without this technique, matched for preoperative risk factors and operative characteristics, was developed for comparison. A comprehensive risk-adjusted analysis of outcomes and morbidity was performed. Results A total of 68,439 patients underwent open ventral hernia repair during the study period (2245 with components separation performed (3.3%) and 66,194 without). In comparison with risk-adjusted controls, use of components separation increased operative duration (additional 83 min), length of stay (6.4 days vs. 3.8 days, p < 0.001), return to the OR rate (5.9% vs. 3.6%, p < 0.001), and 30-day morbidity (10.1% vs. 7.6%, p < 0.001) with no increase in mortality (0.0% in each group). Conclusions Components separation technique for large incisional hernias significantly increases length of stay and postoperative morbidity. Novel strategies to improve short-term outcomes are needed with continued use of this technique. The repair of large abdominal wall hernias is more frequently performed using components separation. While this technique appears to reduce recurrence, morbidity has not been previously studied. When compared to a large cohort, components separation has a higher complication rate than traditional open hernia repair.

Abstract
PURPOSE Given the paucity of literature on outpatient ventral hernia repair (VHR), and that assessment of the safety of outpatient surgical procedures is becoming an active area of investigation, we have performed a multi-institutional retrospective analysis benchmarking rates of 30-day complications and readmissions and identifying predictive factors for these outcomes. METHODS National surgical quality improvement project data files from 2011 to 2012 were reviewed to collect data on all patients undergoing outpatient VHR during that period. The incidence of 30-day peri-operative complication and unplanned readmission was surveyed. We created a multivariate regression model to identify predictive factors for overall, surgical, and medical complications and unplanned readmissions with proper risk adjustment. RESULTS 30-day complication and readmission rates in outpatient VHR were acceptably low. 3% of the queried outpatients experienced an overall complication, 2.1% a surgical complication, and 1.1% a medical complication. 3.3% of all patients were readmitted within 30 days. Upon multivariate analysis, predictors of overall complications included age, BMI, history of Chronic Obstructive Pulmonary Disease (COPD), and total operation time, predictors of surgical complications included age, BMI, total operation time, predictors of medical complications included total operation time, and predictors of unplanned readmissions included history of COPD, bleeding disorder, American Society of Anesthesiologists Class 3, 4, or 5, total operation time, and use of the laparoscopic technique. CONCLUSION We have demonstrated that the risk of peri-operative morbidity in VHR as granularly defined in our study is low in the outpatient setting. Identification of predictive factors will be important to patient risk stratification.

A validated, risk assessment tool for predicting readmission after open ventral hernia repair. Hernia 2015; 20:119-29. [PMID: 26286089 DOI: 10.1007/s10029-015-1413-2] [Citation(s) in RCA: 19] [Impact Index Per Article: 2.1] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/07/2014] [Accepted: 07/29/2015] [Indexed: 01/12/2023]
Abstract
BACKGROUND/PURPOSE To present a validated model that reliably predicts unplanned readmission after open ventral hernia repair (open-VHR). STUDY DESIGN A total of 17,789 open-VHR patients were identified using the 2011-2012 ACS-NSQIP databases. This cohort was subdivided into 70 and 30% random testing and validation samples, respectively. Thirty-day unplanned readmission was defined as unexpected readmission for a postoperative occurrence related to the open-VHR procedure. Independent predictors of 30-day unplanned readmission were identified using multivariable logistic regression on the testing sample (n = 12,452 patients). Subsequently, the predictors were weighted according to β-coefficients to generate an integer-based Clinical Risk Score (CRS) predictive of readmission, which was validated using receiver operating characteristics (ROC) analysis of the validation sample (n = 5337 patients). RESULTS The rate of 30-day unplanned readmission was 4.7%. Independent risk factors included inpatient status at time of open-VHR, operation time, enterolysis, underweight, diabetes, preoperative anemia, length of stay, chronic obstructive pulmonary disease, history of bleeding disorders, hernia with gangrene, and panniculectomy (all P < 0.05). ROC analysis of the validation cohort rendered an area under the curve of 0.71, which demonstrates the accuracy of this prediction model. Predicted incidence within each 5 risk strata was statistically similar to the observed incidence in the validation sample (P = 0.18), further highlighting the accuracy of this model. CONCLUSION We present a validated risk stratification tool for unplanned readmissions following open-VHR. Future studies should determine if implementation of our CRS optimizes safety and reduces readmission rates in open-VHR patients.

Abstract
BACKGROUND Mesh repair of incisional hernias has been consistently shown to diminish recurrence rates after repair, with an increased risk of infectious complications. We present a consecutive series of elective, retrorectus mesh repairs of the abdominal wall and attempt to determine predictors of wound events and recurrence. STUDY DESIGN A retrospective review was performed to include elective, retromuscular mesh repairs of complex incisional hernias from August 2006 to August 2013. Demographics, operative details, and postoperative events including wound events, surgical site infections (SSI), and recurrences were recorded. RESULTS Over the 7-year period, 255 retromuscular mesh repairs of midline incisional defects were performed. Median age of the patients was 58 years, with an average BMI of 32.2 kg/m(2). Average size of the fascial defect was 181.4 cm(2), with recurrent defects making up 48% of repairs. Wound events occurred in 37.7% of cases; SSIs occurred in 19.6% of cases. Recurrence rate was 16.9%, with mean time to recurrence of 19.2 months. With respect to mesh type, recurrences were 16.2% with synthetic, 17.1% for bioabsorbable, and 25% for biologic mesh. When evaluating polypropylene meshes, recurrence was more likely with lightweight mesh (22.9%) vs midweight mesh (10.6%) (p = 0.045). Predictors of SSI included history of mesh infection (odds ratio [OR] 4.8, 95% CI 1.9 to 12.1; p < 0.001) and recurrent repairs (OR 2.5, 95% CI 1.1 to 5.8; p < 0.05). The only predictor of recurrence was the presence of an SSI (OR 3.1, 95% CI 1.5 to 6.3; p < 0.01). CONCLUSIONS Wound events are common after open mesh repairs of complex incisional hernias. Previous mesh infections and recurrent repairs increase the likelihood of an SSI, which significantly increases the risk of recurrence. Recurrences after retrorectus mesh repairs are significantly higher with lightweight compared with mid-weight meshes.

Abstract
PURPOSE The Centers for Medicare and Medicaid Services (CMS), under the Hospitals Readmissions Reductions Program, may withhold regular reimbursements for excessive 30-day readmissions for select diagnoses. Such penalties imply that some readmissions reflect poor clinical decision making or care during the initial hospitalization. We examined factors related to potentially preventable readmissions in CMS patients at a tertiary cancer hospital. METHODS The medical records of all CMS patients with unplanned readmissions within 30 days of index admission were reviewed over 6 months (October 15, 2011-April 15, 2012). Each readmission was classified as not preventable or potentially preventable. Factors associated with potentially preventable readmissions were sought. RESULTS Of 2,531 inpatient admissions in CMS patients over 6 months, 185 patients experienced at least one readmission for 282 total readmissions (11%). Median time to readmission was 9 days (range, 0 to 30 days). The most common causes for first readmission were new diagnoses not present at first admission (n = 43, 23%), new or worsening symptoms due to cancer progression (n = 40, 21%) and complications of procedures (n = 25, 13%). There were 38 (21%) initial readmissions classified as potentially preventable. Use of total parenteral nutrition at the time of discharge was associated with potentially preventable readmission (P = .028). CONCLUSION Most unplanned readmissions to a tertiary cancer hospital are related to progression of disease, new diagnoses, and procedure complications. Minimizing readmissions in complex cancer patients is challenging. Larger multi-institutional datasets are needed to determine a reasonable standard for expected readmission rates.

Abstract
BACKGROUND Recent studies have questioned the efficacy of meniscectomy in older patients with and without evidence of osteoarthritis; however, it continues to be frequently performed. There is limited information about age and other risk factors for adverse events and readmission after the procedure. This knowledge is vital to understand the true risk profile of this common surgery. PURPOSE To investigate if age and medical comorbidities were risk factors for postoperative adverse events and readmission after meniscectomy. STUDY DESIGN Case-control study; Level of evidence, 3. METHODS Patients who underwent arthroscopic meniscectomy between 2005 and 2012 were identified from the American College of Surgeons National Surgical Quality Improvement Program (ACS NSQIP) database. Age≥65 years and medical comorbidities were evaluated as risk factors for any adverse event (AAE), severe adverse events (SAEs), and readmission after meniscectomy using univariate and multivariate analyses. RESULTS A total of 17,774 patients who underwent meniscectomy were identified. The mean age was 53.0±13.6 years. A total of 3420 patients (19.2%) were ≥65 years. Overall, 208 patients (1.17%) had AAE, 203 patients (1.14%) had an SAE, and 102 patients were readmitted (0.97%). Multivariate logistic regression analyses demonstrated no significant differences between age groups for the occurrence of AAE, SAEs, and readmission. Patients with American Society of Anesthesiologists classification≥3 had increased odds of AAE (odds ratio [OR], 1.58), SAEs (OR, 1.59), and readmission (OR, 1.99). Patients with diabetes had increased odds of AAE (OR, 1.57) and SAEs (OR, 1.51). Smokers had increased odds of readmission (OR, 1.67). Patients with pulmonary disease had increased odds of AAE (OR, 1.76) and SAEs (OR, 1.70). CONCLUSION Meniscectomy is a safe procedure in older patients, as age over 65 years did not increase the odds of any of the adverse events studied. However, regardless of age, patients with an increased comorbidity burden and those with a history of smoking are at increased risk of adverse events and/or readmission after the procedure. CLINICAL RELEVANCE Knowledge of these risk factors for adverse events and readmission provides essential information for patient selection and preoperative counseling.
