Functionally dependent status is an independent predictor for worse perioperative outcomes following craniotomy for aneurysmal subarachnoid hemorrhage

Background

Aneurysmal subarachnoid hemorrhage (aSAH) is a medical emergency, and functional status is often a predictor of adverse outcomes perioperatively. Patients with different functional statuses may have different perioperative outcomes during surgery for aSAH. This study retrospectively examines the effect of functional status on specific perioperative outcomes in patients receiving craniotomy for aSAH.

Methods

Patients with aSAH who underwent neurosurgery were identified using International Classification of Diseases (ICD) codes (ICD10, I60; ICD9, 430) in the American College of Surgeons National Surgical Quality Improvement Program (NSQIP) database from 2005 to 2021. Subjects were stratified into two study groups: functionally dependent and functionally independent, based on their documented functional status on NSQIP. Significant preoperative differences were present between groups so a multivariable regression was performed between functionally dependent and independent patients. The 30-day perioperative outcomes of the two groups were compared. Perioperative outcomes included death, major adverse cardiovascular events (MACEs), cardiac complications, stroke, wound complications, renal complications, sepsis, clot formation, pulmonary complications, return to the operating room, operation time >4 h, length of stay longer than 7 days, discharge not to home, and bleeding.

Results

For aSAH patients receiving craniotomy repair, functionally dependent patients had significantly greater rates of MACE, cardiac complications, sepsis, pulmonary complications, and discharge not to home compared to functionally independent patients.

Conclusion

This study shows specific perioperative variables influenced by dependent functional status when treating aSAH through craniotomy, thus leading to a more complicated postoperative course. Additional research is needed to confirm these findings among the specific variables that we analyzed.

Association between blood transfusion and outcomes of free flap head and neck cancer surgery

OBJECTIVE

Investigate the impact of patient risk factors and blood transfusions in Head and Neck free flap surgeries.

STUDY DESIGN

Retrospective chart review.

SETTING

Single tertiary referral center.

METHODS

400 patients were included undergoing free flap reconstruction from 2014 to 2020. The primary outcome measures were red blood cell transfusion and volume transfused. Race, sex, flap location and tissue type, pathology, dependent functional status, length of stay, and cancer recurrence were evaluated for association with red blood cell transfusion intraoperatively and/or postoperatively. Transfusions were indicated on patients with Hemoglobin <7-8 and/or symptomatic anemia. ANOVA and Chi2 statistical analysis were performed. The significance was set at p ≤0.05.

RESULTS

Of the 400 patients included, 58 required red blood cell transfusion. Of these 67.8 % were males, racial demographics included 9.00 % African American, 1.30 % Asian, 1.00 % Hispanic/Latino, 87.8 % White, 1.00 % other. African American patients received a higher volume of transfused red blood cells versus white patients (855.00 mL vs. 437.07 mL, p = 0.005). Length of stay was significantly associated with red blood cell transfusion (5.95 days vs. 7.22 days, p ≤0.001). Dependent functional status and need for red blood cell transfusion were associated (p = 0.002). Type of free flap was associated with need for red blood cell transfusion (p ≤0.001) with anterolateral thigh flaps being the most common resulting in transfusion (34/58).

CONCLUSION

Red blood cell transfusion was significantly associated with race, dependent functional status and length of stay. Certain free flaps have a higher risk of blood transfusion.

The impact of frailty on ventral hernia repair outcomes in a statewide database

INTRODUCTION

Preoperative frailty is a strong predictor of postoperative morbidity in the general surgery population. Despite this, there are a paucity of research examining the effect of frailty on outcomes after ventral hernia repair (VHR), one of the most common abdominal operations in the USA. We examined the association of frailty with short-term postoperative outcomes while accounting for differences in preoperative, operative, and hernia characteristics.

METHODS

We retrospectively reviewed the Michigan Surgery Quality Collaborative Hernia Registry (MSQC-HR) for adult patients who underwent VHR between January 2020 and January 2022. Patient frailty was assessed using the validated 5-factor modified frailty index (mFI5) and categorized as follows: no (mFI5 = 0), moderate (mFI5 = 1), and severe frailty (mFI5 ≥ 2). Our primary outcome was any 30-day complication. Multivariable logistic regression was used to evaluate the association of frailty with outcomes while controlling for patient, operative, and hernia variables.

RESULTS

A total of 4406 patients underwent VHR with a mean age (SD) of 55 (15) years, 2015 (46%) females, and 3591 (82%) white patients. The mean (SD) BMI of the cohort was 33 (8) kg/m2. A total of 2077 (47%) patients had no frailty, 1604 (36%) were moderately frail, and 725 (17%) were severely frail. The median hernia size (interquartile range) was 2.5 cm (1.5-4.0 cm). Severe frailty was associated with increased odds of any complication (adjusted Odds Ratio (aOR) 3.12, 95% CI 1.78-5.47), serious complication (aOR 5.25, 95% CI 2.17-13.19), SSI (aOR 3.41, 95% CI 1.58-7.34), and post-discharge adverse events (aOR 1.70, 95% CI 1.24-2.33).

CONCLUSION

After controlling for patient, operative, and hernia characteristics, frailty was independently associated with increased odds of postoperative complications. These findings highlight the importance of preoperative frailty assessment for risk stratification and to inform patient counseling.

Age-Related Risk Factors in Ventral Hernia Repairs: A Review and Call to Action

BACKGROUND

As the population ages, the incidence of ventral hernias in older adults is increasing. Ventral hernia repairs (VHR) should not be considered low risk operations, particularly in older adults who are disproportionately affected by multiple age-related factors that can complicate surgery and adversely affect outcomes. Although age-related risk factors have been well established in other surgical fields, there is currently little data describing their impact on VHR.

METHODS

We performed a systematic review of the literature to identify studies that examine the effects of age-related risk factors on VHR outcomes. This was conducted using Cochrane Library, Embase, PubMed (Medline), and Google Scholar databases, all updated through June 2020. We selected relevant studies using the keywords, multimorbidity, comorbidities, polypharmacy, functional dependence, functional status, frailty, cognitive impairment, dementia, sarcopenia, and malnutrition. Primary outcomes include mortality and overall complications following VHR.

RESULTS

We summarize the evidence basis for the significance of age-related risk factors in elective surgery and discuss how these factors increase the risk of adverse outcomes following VHR. In particular, we explore the impact of the following risk factors: multimorbidity, polypharmacy, functional dependence, frailty, cognitive impairment, sarcopenia, and malnutrition. As opposed to chronological age itself, age-related risk factors are more clinically relevant in determining VHR outcomes.

CONCLUSIONS

Given the increasing complexity of VHR, addressing age-related risk factors pre-operatively has the potential to improve surgical outcomes in older adults. Preoperative risk assessment and individualized prehabilitation programs aimed at improving patient-centered outcomes may be particularly useful in this population.

Dependent Functional Status is a Risk Factor for Perioperative and Postoperative Complications After Total Hip Arthroplasty

BACKGROUND

As the population ages, the need for total hip arthroplasty (THA) will increase. However, this will be associated with an increase in comorbidities and a decrease in the ability to independently perform activities of daily living (ADLs). This study was designed to evaluate the impact preoperative functional status has on short-term outcomes after THA.

METHODS

Primary THAs performed from 2012 to 2016 were identified in the National Surgical Quality Improvement Program database. Final analysis included 115,590 cases. Patients who could perform all ADLs were classified as independent functional status (n = 113,436), and patients requiring assistance with ADLs were classified as dependent functional status (n = 2154). Univariate analysis was used to compare perioperative outcomes and 30-day complication rates. Multivariate regression was then applied to determine if preoperative dependent functional status was an independent risk factor for adverse outcomes.

RESULTS

Functionally dependent patients were more likely to experience operative times >120 minutes (odds ratio [OR] = 1.39; P < .001), hospital stays >10 days (OR = 2.96; P < .001), and nonhome discharge (OR = 2.53; P < .001). Dependent functional status was also an independent risk factor for mortality (OR = 3.00; P = .001), reoperation (OR = 1.39; P = .015), readmission (OR = 1.75; P < .001), superficial surgical site infection (OR = 1.96; P = .002), wound dehiscence (OR = 2.72; P = .034), pneumonia (OR = 2.16; P = .001), reintubation (OR = 2.31; P = .007), prolonged ventilator use (OR = 3.01; P = .009), renal failure necessitating dialysis (OR = 3.94; P = .002), urinary tract infection (OR = 1.78; P = .001), blood transfusion (OR = 1.75; P < .001), and sepsis (OR = 2.38; P = .001).

CONCLUSIONS

Functionally dependent patients undergoing THA are at higher risk of mortality, adverse perioperative outcomes, and complications. These data may aid for patient counseling and risk stratification.

Preoperative functional health status is a predictor of short-term postoperative morbidity and mortality after bariatric surgery

BACKGROUND

Functional health status (FHS) is the ability to perform activities of daily living without caregiver assistance.

OBJECTIVES

The primary aim of this study was to determine the impact of impaired preoperative FHS on morbidity and mortality within 30 days of bariatric surgery.

SETTING

Academic medical center in the United States.

METHODS

The Metabolic and Bariatric Surgery Accreditation and Quality Improvement Program 2015 data set was queried for primary minimally invasive bariatric procedures. The demographic characteristics and perioperative details of patients who were functionally independent were compared with patients with impaired FHS. Multivariable logistic regression analysis was performed to determine the odds of developing a perioperative complication or death for patients with impaired functional health.

RESULTS

Of patients, 1515 (1.0%) were reported as having impaired FHS and 147,195 patients (99.0%) were independent before surgery. Patients with impaired FHS experienced significantly longer length of hospital stays (2.4 versus 1.8 d; P < .0001), a higher morbidity (adjusted odds ratio 1.5; P <0.0001), and higher mortality (adjusted odds ratio 2.1; P < .0001). Impaired FHS resulted in significantly increased rate of unplanned admissions to the intensive care unit, interventions, reoperations, and readmissions within 30 days of surgery.

CONCLUSIONS

Patients with impaired FHS preoperatively have a significantly increased risk of short-term morbidity and mortality after bariatric surgery. The results of this study highlight the importance of establishing quality initiatives focused on improving short-term outcomes for patients with impaired functional health status.

Electronically captured, patient-reported physical function: an important vital sign in obesity medicine

OBJECTIVES

Impaired physical function (i.e., inability to walk 200 feet, climb a flight of stairs or perform activities of daily living) predicts poor clinical outcomes and adversely impacts medical and surgical weight management. However, routine assessment physical function is seldom performed clinically. The PROMIS Physical Function Short Form 20a (SF-20a) is a validated questionnaire for assessing patient reported physical function, which includes published T-score percentiles adjusted for gender, age and education. However, the effect that increasing levels of obesity has on these percentiles is unclear. We hypothesized that physical function would decline with increasing level of obesity independent of gender, age, education and comorbidity.

MATERIALS AND METHODS

This study included 1,627 consecutive weight management patients [(mean ± SEM), 44.7 ± 0.3 years and 45.1 ± 0.2 kg/m2] that completed the PROMIS SF-20a during their initial consultation. We evaluated the association between obesity level and PROMIS T-score percentiles using multiple linear regression adjusting for gender, age, education and Charlson Comorbidity Index (CCI).

RESULTS

Multiple linear regression T-score percentiles were lower in obesity class 2 (-12.4%tile, p < 0.0001), class 3 (-17.0%tile, p < 0.0001) and super obesity (-25.1%tile, p < 0.0001) compared to class 1 obesity.

CONCLUSION

In patients referred for weight management, patient reported physical function was progressively lower in a dose-dependent fashion with increasing levels of obesity, independent of gender, age, education and CCI.

Open repair of large abdominal wall hernias with and without components separation; an analysis from the ACS-NSQIP database

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.

Preoperative functional health status may predict outcomes after elective colorectal surgery for malignancy

BACKGROUND

Several studies suggest that preoperative functional health status (FHS) affects postoperative outcomes after ventral hernia repair, hepatic resections, and infrainguinal by-pass surgery. However, little is known about the proficiency of FHS in terms of preoperative outcome prediction of patients who undergo elective resection for colorectal cancer.

METHODS

All patients who underwent elective colorectal resections for malignancy between 2005 and 2009 were identified from the American College of Surgeons National Surgical Quality Improvement Program. We classified patients into three groups according to their preoperative FHS: independent (IND), partially dependent (PDN), and totally dependent (TDN). Multivariable techniques were used to evaluate the impact of FHS on postoperative outcomes. Outcomes of laparoscopic and open procedures in patients with dependent FHS were also compared.

RESULTS

In total, 25,591 patients included (94.2% IND, 5.1% PDN, and 0.71% TDN). Surgical, infectious, pulmonary, cardiovascular, renal, neurological complications, and mortality rate showed a linear progression that paralleled a decline in preoperative FHS of the patients (p < 0.05). Laparoscopic technique was associated with better outcomes in terms of reduced length of total hospital stay, decreased infectious complication rate, and mortality with comparable operating time in patients with dependent (PDN and TDN) FHS (p < 0.05).

CONCLUSIONS

Functional health status may predict postoperative outcomes after colorectal cancer surgery. A detailed preoperative evaluation, providing an optimization period before surgery if necessary, and increased utilization of laparoscopic technique may improve outcomes after elective colorectal resections for malignancy in patients who are partially or TDN.

Spine surgeon specialty is not a risk factor for 30-day complication rates in single-level lumbar fusion: a propensity score-matched study of 2528 patients

STUDY DESIGN

Multicenter retrospective cohort study.

OBJECTIVE

To investigate the impact of spine surgeon specialty on 30-day complication rates in patients undergoing single-level lumbar fusion.

SUMMARY OF BACKGROUND DATA

Operative care of the spine is delivered by surgeons who undergo either orthopedic or neurosurgical training. It is currently unknown whether surgeon specialty has an impact on 30-day complication rates in patients undergoing single-level lumbar fusion.

METHODS

The American College of Surgeons National Surgical Quality Improvement Program database was retrospectively reviewed to identify all patients who underwent single-level lumbar fusion procedures during 2006-2011. Propensity score matching analysis was employed to reduce baseline differences in patient characteristics. Univariate and multivariate analyses were performed to assess the impact of spine surgeon specialty on 30-day complication rates.

RESULTS

A total of 2970 patients were included for analysis. After propensity matching, 1264 pairs of well-matched patients remained in the cohort. Overall complication rates in the unadjusted data set were 7.3% and 7.1% for the neurosurgery and orthopedic surgery cohort, respectively. Our multivariate analysis revealed that compared with the neurosurgery cohort, the orthopedic surgery cohort did not have statistically significant differences in odds ratios (OR) for development of any complication (OR, 0.95; 95% confidence interval [CI], 0.69-1.30; P = 0.740). Similarly, spine surgeon specialty was not a risk factor in any of the specific complications studied, including medical complications (OR, 1.11; 95% CI, 0.77-1.60; P = 0.583), surgical complications (OR, 0.76; 95% CI, 0.46-1.26; P = 0.287), or reoperation (OR, 1.10; 95% CI, 0.76-1.60; P = 0.618).

CONCLUSION

Our analysis demonstrates that spine surgeon specialty is not a risk factor for any of the reported 30-day complications in patients undergoing single-level lumbar fusion. These data support the currently dichotomous paradigm of training for spine surgeons. Further research is warranted to validate this relationship in other spine procedures and for other outcomes.

Patient Satisfaction, chronic pain, and functional status following laparoscopic ventral hernia repair

BACKGROUND

Ventral hernia repairs are one of the most common surgeries performed. Symptoms are the most common motivation for repair. Unfortunately, outcomes of repair are typically measured in recurrence and infection rather than patient focused results. We correlated factors associated with decreased patient satisfaction, chronic pain, and diminished functional status following laparoscopic ventral hernia repair (LVHR) METHODS: A retrospective study of 201 patients from two affiliated institutions was performed. Patient satisfaction, chronic abdominal pain, pain scores, and Activities Assessment Scale results were obtained in 122 patients. Results were compared with univariate and multivariate analysis.

RESULTS

Thirty-two (25.4%) patients were dissatisfied with their LVHR while 21 (17.2%) patients had chronic abdominal pain and 32 (26.2%) patients had poor functional status following LVHR. Decreased patient satisfaction was associated with perception of poor cosmetic outcome (OR 17.3), eventration (OR 10.2), and chronic pain (OR 1.4). Chronic abdominal pain following LVHR was associated with incisional hernia (OR 9.0), recurrence (OR 4.3), eventration (OR 6.0), mesh type (OR 1.9), or ethnicity (OR 0.10). Decreased functional status with LVHR was associated with mesh type used (OR 3.7), alcohol abuse (OR 3.4), chronic abdominal pain (OR 1.3), and age (OR 1.1).

CONCLUSIONS

One-fourth of patients have poor quality outcome following LVHR. These outcomes are affected by perception of cosmesis, eventration, chronic pain, hernia type, recurrence, mesh type, and patient characteristics/co-morbidities. Closing central defects and judicious mesh selection may improve patient satisfaction and function. Focus on patient-centered outcomes is warranted.

Financial implications of ventral hernia repair: a hospital cost analysis

INTRODUCTION

Complicated ventral hernias are often referred to tertiary care centers. Hospital costs associated with these repairs include direct costs (mesh materials, supplies, and nonsurgeon labor costs) and indirect costs (facility fees, equipment depreciation, and unallocated labor). Operative supplies represent a significant component of direct costs, especially in an era of proprietary synthetic meshes and biologic grafts. We aim to evaluate the cost-effectiveness of complex abdominal wall hernia repair at a tertiary care referral facility.

METHODS

Cost data on all consecutive open ventral hernia repairs (CPT codes 49560, 49561, 49565, and 49566) performed between 1 July 2008 and 31 May 2011 were analyzed. Cases were analyzed based upon hospital status (inpatient vs. outpatient) and whether the hernia repair was a primary or secondary procedure. We examined median net revenue, direct costs, contribution margin, indirect costs, and net profit/loss. Among primary hernia repairs, cost data were further analyzed based upon mesh utilization (no mesh, synthetic, or biologic).

RESULTS

Four-hundred and fifteen patients underwent ventral hernia repair (353 inpatients and 62 outpatients); 173 inpatients underwent ventral hernia repair as the primary procedure; 180 inpatients underwent hernia repair as a secondary procedure. Median net revenue ($17,310 vs. 10,360, p < 0.001) and net losses (3,430 vs. 1,700, p < 0.025) were significantly greater for those who underwent hernia repair as a secondary procedure. Among inpatients undergoing ventral hernia repair as the primary procedure, 46 were repaired without mesh; 79 were repaired with synthetic mesh and 48 with biologic mesh. Median direct costs for cases performed without mesh were $5,432; median direct costs for those using synthetic and biologic mesh were $7,590 and 16,970, respectively (p < .01). Median net losses for repairs without mesh were $500. Median net profit of $60 was observed for synthetic mesh-based repairs. The median contribution margin for cases utilizing biologic mesh was -$4,560, and the median net financial loss was $8,370. Outpatient ventral hernia repairs, with and without synthetic mesh, resulted in median net losses of $1,560 and 230, respectively.

CONCLUSIONS

Ventral hernia repair is associated with overall financial losses. Inpatient synthetic mesh repairs are essentially budget neutral. Outpatient and inpatient repairs without mesh result in net financial losses. Inpatient biologic mesh repairs result in a negative contribution margin and striking net financial losses. Cost-effective strategies for managing ventral hernias in a tertiary care environment need to be developed in light of the financial implications of this patient population.

Predictors of poor outcomes in functionally dependent patients undergoing ventral hernia repair

BACKGROUND

Preoperative functional health status has been shown previously to affect outcomes following ventral hernia repair. The objective of this study was to identify specific factors that contribute to morbidity and mortality in functionally dependent patients who undergo elective ventral hernia repair.

METHODS

We reviewed all patients in the ACS NSQIP database who underwent elective ventral hernia repair from 2005 to 2009. Patients were selected based on the following CPT codes: 49560, 49561, 49565, 49566, 49568, 49570, 49572, 49585, 49587, 49652, 49653, 49654, 49655, 49656, and 49657. Only patients classified as partially or totally dependent were included in this study. Thirty-day outcomes included mortality, wound occurrences, pulmonary occurrences, venous thromboembolism, development of sepsis/shock, renal failure/insufficiency, and cardiovascular events. We analyzed risk factors using multivariate analyses.

RESULTS

We identified 75,865 patients who underwent elective ventral hernia repair, of which 1,144 were classified as functionally dependent. Overall, major morbidity was observed in 211 (18.4 %) patients. There was no statistically significant difference in any measurable outcomes between laparoscopic and open hernia repairs. Increasing age proved to be an independent predictor of mortality, with an odds ratio of 1.63 (95 % confidence interval (CI) 1.27-2.12) for each 10 years of age beyond the mean. Ascites and preoperative renal failure also were identified as independent predictors of mortality, with odds ratios of 9.7 and 11.5, respectively. Preoperative pulmonary compromise was shown to be an independent predictor of both mortality and major morbidity, with odds ratios of 4.1 and 2.47, respectively.

CONCLUSIONS

Elective ventral hernia repair in the functionally dependent patient population has significant morbidity and mortality. Increasing age, ascites, preoperative renal failure, and preoperative pulmonary compromise are independent predictors of 30-day mortality. Nonoperative management should be strongly considered in the presence of these risk factors. Further studies are needed to determine optimum management strategies for functionally dependent patients with ventral hernias.
