Predictors of Mortality Up to 1 Year After Emergency Major Abdominal Surgery in Older Adults

Cesena guidelines: WSES consensus statement on laparoscopic-first approach to general surgery emergencies and abdominal trauma

BACKGROUND

Laparoscopy is widely adopted across nearly all surgical subspecialties in the elective setting. Initially finding indication in minor abdominal emergencies, it has gradually become the standard approach in the majority of elective general surgery procedures. Despite many technological advances and increasing acceptance, the laparoscopic approach remains underutilized in emergency general surgery and in abdominal trauma. Emergency laparotomy continues to carry a high morbidity and mortality. In recent years, there has been a growing interest from emergency and trauma surgeons in adopting minimally invasive surgery approaches in the acute surgical setting. The present position paper, supported by the World Society of Emergency Surgery (WSES), aims to provide a review of the literature to reach a consensus on the indications and benefits of a laparoscopic-first approach in patients requiring emergency abdominal surgery for general surgery emergencies or abdominal trauma.

METHODS

This position paper was developed according to the WSES methodology. A steering committee performed the literature review and drafted the position paper. An international panel of 54 experts then critically revised the manuscript and discussed it in detail, to develop a consensus on a position statement.

RESULTS

A total of 323 studies (systematic review and meta-analysis, randomized clinical trial, retrospective comparative cohort studies, case series) have been selected from an initial pool of 7409 studies. Evidence demonstrates several benefits of the laparoscopic approach in stable patients undergoing emergency abdominal surgery for general surgical emergencies or abdominal trauma. The selection of a stable patient seems to be of paramount importance for a safe adoption of a laparoscopic approach. In hemodynamically stable patients, the laparoscopic approach was found to be safe, feasible and effective as a therapeutic tool or helpful to identify further management steps and needs, resulting in improved outcomes, regardless of conversion. Appropriate patient selection, surgeon experience and rigorous minimally invasive surgical training, remain crucial factors to increase the adoption of laparoscopy in emergency general surgery and abdominal trauma.

CONCLUSIONS

The WSES expert panel suggests laparoscopy as the first approach for stable patients undergoing emergency abdominal surgery for general surgery emergencies and abdominal trauma.

Risk factors for in-hospital mortality after emergency colorectal surgery in octogenarians: results of a cohort study from a referral center

PURPOSE

The objective of this study was to investigate predictive factors of mortality in emergency colorectal surgery in octogenarian patients.

METHODS

It is a retrospective cohort study conducted at a single-institution tertiary referral center. Consecutive patients who underwent emergency colorectal surgery between January 2015 and January 2020 were identified. The primary endpoint was 30-day mortality. Univariate and multivariate analyses were performed using a logistic regression model.

RESULTS

A total of 111 patients were identified (43 men, 68 women). Mean age was 85.7 ± 3.7 years (80-96). Main diagnoses included complicated sigmoiditis in 38 patients (34.3%), cancer in 35 patients (31.5%), and ischemic colitis in 31 patients (27.9%). An ASA score of 3 or higher was observed in 88.3% of patients. The mean Charlson score was 5.9. The Possum score was 35.9% for mortality and 79.3% for morbidity. The 30-day mortality rate was 25.2%. Univariate analysis of preoperative risk factors for mortality shows that the history of valvular heart disease (p = 0.008), intensive care unit provenance (p = 0.003), preoperative sepsis (p < 0.001), diagnosis of ischemic colitis (p = 0.012), creatinine (p = 0.006) and lactate levels (p = 0.01) were significantly associated with 30-day mortality, and patients coming from home had a lower 30-day mortality rate (p = 0.018). Intraoperative variables associated with 30-day mortality included ileostomy creation (p = 0.022) and temporary laparostomy (p = 0.004). At multivariate analysis, only lactate (p = 0.032) and creatinine levels (p = 0.027) were found to be independent predictors of 30-day mortality, home provenance was an independent protective factor (p = 0.004). Mean follow-up was 3.4 years. Survival at 1 and 3 years was 57.6 and 47.7%.

CONCLUSION

Emergency colorectal surgery is challenging. However, age should not be a contraindication. The 30-day mortality rate (25.2%) is one of the lowest in the literature. Hyperlactatemia (> 2mmol/L) and creatinine levels appear to be independent predictors of mortality.

The Clinical Frailty Scale (CFS) as an Independent Prognostic Factor for Patients ≥80 Years with Small Bowel Obstruction (SBO)

BACKGROUND

SBO is a potentially life-threatening condition that often affects older patients. Frailty, more than age, is expected to play a crucial role in predicting SBO prognosis in this population. This study aims to define the influence of Clinical Frailty Scale (CFS) on mortality and major complications in patients ≥80 years with diagnosis of SBO at the emergency department (ED).

METHODS

All patients aged ≥80 years admitted to our ED for SBO from January 2015 to September 2020 were enrolled. Frailty was assessed through the CFS, and then analyzed both as a continuous and a dichotomous variable. The endpoints were in-hospital mortality and major complications.

RESULTS

A total of 424 patients were enrolled. Higher mortality (20.8% vs 8.6%, p<0.001), longer hospital stay (9 [range 5-14] days vs 7 [range 4-12] days, p=0.014), and higher rate of major complications (29.9% vs 17.9%, p=0.004) were associated with CFS ≥7. CFS score and bloodstream infection were the only independent prognostic factors for mortality (OR 1.72 [CI: 1.29-2.29], p<0.001; OR 4.69 [CI: 1.74-12.6], p=0.002, respectively). Furthermore, CFS score, male sex and surgery were predictive factors for major complications (OR 1.41 [CI: 1.13-1.75], p=0.002; OR 1.67 [CI: 1.03-2.71], p=0.038); OR 1.91 [CI: 1.17-3.12], p=0.01; respectively). At multivariate analysis, for every 1-point increase in CFS score, the odds of mortality and the odds of major complications increased 1.72-fold and 1.41-fold, respectively.

CONCLUSION

The increase in CFS is directly associated with an increased risk of mortality and major complications. The presence of severe frailty could effectively predict an increased risk of in-hospital death regardless of the treatment administered. The employment of CFS in elderly patients could help the identification of the need for closer monitoring and proper goals of care.

Enhanced Recovery After Surgery (ERAS®) Society Consensus Guidelines for Emergency Laparotomy Part 3: Organizational Aspects and General Considerations for Management of the Emergency Laparotomy Patient

BACKGROUND

This is Part 3 of the first consensus guidelines for optimal care of patients undergoing emergency laparotomy using an enhanced recovery after surgery (ERAS) approach. This paper addresses organizational aspects of care.

METHODS

Experts in management of the high-risk and emergency general surgical patient were invited to contribute by the International ERAS® Society. PubMed, Cochrane, Embase, and MEDLINE database searches were performed for ERAS elements and relevant specific topics. Studies were selected with particular attention to randomized clinical trials, systematic reviews, meta-analyses and large cohort studies, and reviewed and graded using the Grading of Recommendations, Assessment, Development and Evaluation system. Recommendations were made on the best level of evidence, or extrapolation from studies on elective patients when appropriate. A modified Delphi method was used to validate final recommendations.

RESULTS

Components of organizational aspects of care were considered. Consensus was reached after three rounds of a modified Delphi process.

CONCLUSIONS

These guidelines are based on best current available evidence for organizational aspects of an ERAS® approach to patients undergoing emergency laparotomy and include discussion of less common aspects of care for the surgical patient, including end-of-life issues. These guidelines are not exhaustive but pull together evidence on important components of care for this high-risk patient population. As much of the evidence is extrapolated from elective surgery or emergency general surgery (not specifically laparotomy), many of the components need further evaluation in future studies.

Prevalence of unpaid caregiving, pain, and depression in older seriously ill patients undergoing elective surgery

INTRODUCTION

Serious illness is a life-limiting condition negatively impacting daily function, quality of life, or excessively straining caregivers. Over 1 million older seriously ill adults undergo major surgery annually, and national guidelines recommend that palliative care be available to all seriously ill patients. However, the palliative care needs of elective surgical patients are incompletely described. Understanding baseline caregiving needs and symptom burden among seriously ill older surgical patients could inform interventions to improve outcomes.

METHODS

Using Health and Retirement Study data (2008-2018) linked to Medicare claims, we identified patients ≥66 years who met an established serious illness definition from administrative data and underwent major elective surgery using Agency for Healthcare Research and Quality (AHRQ) criteria. Descriptive analyses were performed for preoperative patient characteristics, including: unpaid caregiving (no or yes); pain (none/mild or moderate/severe); and depression (no, CES-D < 3, or yes, CES-D ≥ 3). Multivariable regression was performed to examine the association between unpaid caregiving, pain, depression, and in-hospital outcomes, including hospital days (days admitted between discharge date and one-year post-discharge), in-hospital complications (no or yes), and discharge destination (home or non-home).

RESULTS

Of the 1343 patients, 55.0% were female and 81.6% were non-Hispanic White. Mean age was 78.0 (SD 6.8); 86.9% had ≥2 comorbidities. Before admission, 27.3% of patients received unpaid caregiving. Pre-admission pain and depression were 42.6% and 32.8%, respectively. Baseline depression was significantly associated with non-home discharge (OR 1.6, 95% CI 1.2-2.1, p = 0.003), while baseline pain and unpaid caregiving needs were not associated with in-hospital or post-acute outcomes in multivariable analysis.

CONCLUSIONS

Prior to elective surgery, older adults with serious illnesses have high unpaid caregiving needs and a prevalence of pain and depression. Baseline depression alone was associated with discharge destinations. These findings highlight opportunities for targeted palliative care interventions throughout the surgical encounter.

Assessing and managing frailty in emergency laparotomy: a WSES position paper

Many countries are facing an aging population. As people live longer, surgeons face the prospect of operating on increasingly older patients. Traditional teaching is that with older age, these patients face an increased risk of mortality and morbidity, even to a level deemed too prohibitive for surgery. However, this is not always true. An active 90-year-old patient can be much fitter than an overweight, sedentary 65-year-old patient with comorbidities. Recent literature shows that frailty-an age-related cumulative decline in multiple physiological systems, is therefore a better predictor of mortality and morbidity than chronological age alone. Despite recognition of frailty as an important tool in identifying vulnerable surgical patients, many surgeons still shun objective tools. The aim of this position paper was to perform a review of the existing literature and to provide recommendations on emergency laparotomy and in frail patients. This position paper was reviewed by an international expert panel composed of 37 experts who were asked to critically revise the manuscript and position statements. The position paper was conducted according to the WSES methodology. We shall present the derived statements upon which a consensus was reached, specifying the quality of the supporting evidence and suggesting future research directions.

Analyzing Impact of Multimorbidity on Long-Term Outcomes after Emergency General Surgery: A Retrospective Observational Cohort Study

BACKGROUND

Little is known about the impact of multimorbidity on long-term outcomes for older emergency general surgery patients.

STUDY DESIGN

Medicare beneficiaries, age 65 and older, who underwent operative management of an emergency general surgery condition were identified using Centers for Medicare & Medicaid claims data. Patients were classified as multimorbid based on the presence of a Qualifying Comorbidity Set (a specific combination of comorbid conditions known to be associated with increased risk of in-hospital mortality in the general surgery setting) and compared with those without multimorbidity. Risk-adjusted outcomes through 180 days after discharge from index hospitalization were calculated using linear and logistic regressions.

RESULTS

Of 174,891 included patients, 45.5% were identified as multimorbid. Multimorbid patients had higher rates of mortality during index hospitalization (5.9% vs 0.7%, odds ratio [OR] 3.05, p < 0.001) and through 6 months (17.1% vs 3.4%, OR 2.33, p < 0.001) after discharge. Multimorbid patients experienced higher rates of readmission at 1 month (22.9% vs 11.4%, OR 1.48, p < 0.001) and 6 months (38.2% vs 21.2%, OR 1.48, p < 0.001) after discharge, lower rates of discharge to home (42.5% vs 74.2%, OR 0.52, p < 0.001), higher rates of discharge to rehabilitation/nursing facility (28.3% vs 11.3%, OR 1.62, p < 0.001), greater than double the use of home oxygen, walker, wheelchair, bedside commode, and hospital bed (p < 0.001), longer length of index hospitalization (1.33 additional in-patient days, p < 0.001), and higher costs through 6 months ($5,162 additional, p < 0.001).

CONCLUSIONS

Older, multimorbid patients experience worse outcomes, including survival and independent function, after emergency general surgery than nonmultimorbid patients through 6 months after discharge from index hospitalization. This information is important for setting recovery expectations for high-risk patients to improve shared decision-making.

Multimorbidity Confers Greater Risk for Older Patients in Emergency General Surgery Than the Presence of Multiple Comorbidities: A Retrospective Observational Study

BACKGROUND

Little is known about the impact of multimorbidity on outcomes for older emergency general surgery patients.

OBJECTIVE

The aim was to understand whether having multiple comorbidities confers the same amount of risk as specific combinations of comorbidities (multimorbidity) for a patient undergoing emergency general surgery.

RESEARCH DESIGN

Retrospective observational study using state discharge data.

SUBJECTS

Medicare beneficiaries who underwent an operation for an emergency general surgery condition in New York, Florida, or Pennsylvania (2012-2013).

MEASURES

Patients were classified as multimorbid using Qualifying Comorbidity Sets (QCSs). Outcomes included in-hospital mortality, hospital length of stay and discharge status.

RESULTS

Of 312,160 patients, a large minority (37.4%) were multimorbid. Non-QCS patients did not have a specific combination of comorbidities to satisfy a QCS, but 64.1% of these patients had 3+ comorbid conditions. Multimorbidity was associated with increased in-hospital mortality (10.5% vs. 3.9%, P <0.001), decreased rates of discharge to home (16.2% vs. 37.1%, P <0.001), and longer length of stay (10.4 d±13.5 vs. 6.7 d±9.3, P <0.001) when compared with non-QCS patients. Risks varied between individual QCSs.

CONCLUSIONS

Multimorbidity, defined by satisfying a specific QCS, is strongly associated with poor outcomes for older patients requiring emergency general surgery in the United States. Variation in risk of in-hospital mortality, discharge status, and length of stay between individual QCSs suggests that multimorbidity does not carry the same prognostic weight as having multiple comorbidities-the specifics of which are important in setting expectations for individual, complex patients.

Predicting the Need for Surgery in Uncomplicated Adhesive Small Bowel Obstruction: A Scoring Tool

INTRODUCTION

Nonoperative treatment can be attempted for uncomplicated adhesive small bowel obstruction (ASBO), but carries a risk of delayed surgery. Highlighting initial parameters predicting risk of failure of nonoperative management would be of great interest.

METHODS

Patients initially managed conservatively for uncomplicated ASBO were retrospectively analyzed. Univariate and multivariate analysis were performed to identify predictive failure's factors. Based on the risk factors, a score was created and then prospectively validated in a different patients' population.

RESULTS

Among 171 patients included, 98 (57.3%) were successfully managed conservatively. In a multivariate analysis, three independent nonoperative management failure's factors were identified: Charlson Index ≥4 (P = 0.016), distal obstruction (P = 0.009), and maximum small bowel diameter over vertical abdominal diameter ratio >0.34 (P = 0.023). A score of two or three was associated with a risk of surgery of 51.4% or 70.3% in the retrospective analysis and 62.2% or 75% in the validation cohort, respectively.

CONCLUSIONS

This clinical-radiological score may help guide surgical decision-making in uncomplicated ASBO. A high score (≥2) was predictive of failure of nonoperative management. This tool could assist surgeons to determine who would benefit from early surgery.

Emergency Laparotomy

Emergency laparotomy is a high-risk surgical procedure with mortality and morbidity up to 10 times higher than for a similar procedure performed electively. An enhanced recovery approach has been shown to improve outcomes. A focus on rapid correction of underlying deranged acute physiology and proactive management of conditions associated with aging such as frailty and delirium are key. Patients are at high risk of complications and prevention and avoidance of failure to rescue are essential to improve outcomes. Other enhanced recovery components such as opioid-sparing analgesia and early postoperative mobilization are beneficial.

Functional and Cognitive Decline Among Older Adults After High-risk Surgery

OBJECTIVE

The aim of this study was to determine whether older adults are at higher risk of lasting functional and cognitive decline after surgery, and the impact of decline on survival and healthcare use.

SUMMARY BACKGROUND DATA

Patient-centered outcomes after surgery are poorly characterized.

METHODS

Using data from the Health and Retirement Study linked with Medicare, we matched older adults (≥65 years) who underwent one of 163 high-risk elective operations (ie, inpatient mortality of ≥1%) with nonsurgical controls between 1992 and 2012. Functional decline was defined as an increase in the number of activities of daily living (ADLs) and/or instrumental activities of daily living (IADLs) requiring assistance from baseline. Cognitive decline was defined by worse response to a test of memory and mental processing from baseline. Using logistic regression, we examined whether surgery was associated with functional and cognitive decline, and whether declines were associated with poorer survival and increased healthcare use.

RESULTS

The matched cohort of patients who did not undergo surgery consisted of 3591 (75%) participants compared to 1197 (25%) who underwent surgery. Patients who underwent surgery were at higher risk of functional and cognitive declines [adjusted odds ratio (aOR) 1.52, 95% confidence interval (CI): 1.23-1.87 and aOR 1.32, 95% CI: 1.03-1.71]. Declines were associated with poorer long-term survival [hazard ratio (HR) 1.67, 95% CI: 1.43-1.94 and HR 1.35, 95% CI: 1.15-1.58], and were significantly associated with nearly all measures of increased healthcare utilization (P < 0.001).

CONCLUSION

Older adults undergoing high-risk surgery are at increased risk of developing lasting functional and cognitive declines.

The significance of comorbidity burden among older patients undergoing abdominal emergency or elective surgery

BACKGROUND

Comorbidities may cause complications in perioperative care and affect treatment outcomes of older patients. The study aim was to analyse comorbidity burdens with respect to their predictive power in outcome prediction in elderly qualified for abdominal elective or emergency surgery.

METHODS

Consecutive patients undergoing major abdominal surgery between 2010 and 2017 at a secondary referral hospital were included in the retrospective study, for a total of 1586 patients. To explain the relationship between the comorbidity types and 30-day mortality and morbidity logistic regression analysis was performed. Morbidity was assessed using the Clavien-Dindo Score. Major complications were defined as a C-D score ≥ 3. We also presented the data concerning need for reoperation and ICU admission.

RESULTS

85.9% of patients had at least one comorbidity. In the group of emergency patients age and number of comorbidities were independent risk factors of 30-day mortality and major morbidity. In elective patients age, dementia (OR:3.52; 95%CI:1.35-9.20) and kidney disease (OR:1.64; 95%CI:1.04-2.57) were found to be independent risk factors of 30-day postoperative mortality. Age (1.04; 95%CI:1.00-1.08) and heart disease (OR:1.30, 95%CI:1.04-1.63) were found to be independent risk factors of 30-day major morbidity.

CONCLUSIONS

In patients undergoing elective surgery 30-day mortality and morbidity was associated with age. 30-day mortality, but not morbidity was associated with kidney disease and dementia. 30-day morbidity, but not mortality, was associated with heart disease.

Inner Deliberations of Surgeons Treating Critically-ill Emergency General Surgery Patients: A Qualitative Analysis

BACKGROUND

30% of elderly patients who require emergency general surgery (EGS) die in the year after the operation. Preoperative discussions can determine whether patients receive preference-sensitive care. Theoretically, surgeons frame their conversations after systematically assessing the risks and benefits of management options based on the clinical characteristics of each case. However, little is known about how surgeons actually deliberate about those options.

OBJECTIVE

To identify variables that influence surgeons' assessment of management options for critically-ill EGS patients.

METHODS

We conducted semi-structured interviews with 40 general surgeons in western Pennsylvania who worked in a variety of hospital settings. Interviews explored perioperative decision-making by asking surgeons to think aloud about selected memorable cases and a standardized case vignette of a frail patient with acute mesenteric ischemia. We used constant comparative methods to analyze interview transcripts and inductively developed a framework for the decision-making process.

RESULTS

Surgeons averaged 13 years (standard deviation (SD) 10.4) of experience; 40% specialized in trauma/acute care surgery. Important themes regarding the main topic of "perioperative decision-making" included many considerations beyond the clinical characteristics of cases. Surgeons described the importance of variables ranging from the availability of institutional resources to professional norms. Surgeons often remarked on their desire to achieve individual flow, team efficiency, and concordant expectations of treatment and prognosis with patients.

CONCLUSIONS

This is the first study to explore how surgeons decide among management options for critically-ill EGS patients. Surgeons' decision-making reflected a broad array of clinical, personal, and institutional variables. Effective interventions to ensure preference-sensitive care for EGS patients must address all of these variables.

Physical and Cognitive Function Assessment to Predict Postoperative Outcomes of Abdominal Surgery

BACKGROUND

Current evaluation methods to assess physical and cognitive function are limited and often not feasible in emergency settings. The upper-extremity function (UEF) test to assess physical and cognitive performance using wearable sensors. The purpose of this study was to examine the (1) relationship between preoperative UEF scores with in-hospital outcomes; and (2) association between postoperative UEF scores with 30-d adverse outcomes among adults undergoing emergent abdominal surgery.

METHODS

We performed an observational, longitudinal study among adults older than 40 y who presented with intra-abdominal symptoms. The UEF tests included a 20-sec rapid repetitive elbow flexion (physical function), and a 60-sec repetitive elbow flexion at a self-selected pace while counting backwards by threes (cognitive function), administered within 24-h of admission and within 24-h prior to discharge. Multiple logistic regression models assessed the association between UEF and outcomes. Each model consisted of the in-hospital or 30-d post-discharge outcome as the dependent variable, preoperative UEF physical and cognitive scores as hypothesis covariates, and age and sex as adjuster covariates.

RESULTS

Using UEF physical and cognitive scores to predict in-hospital outcomes, an area under curve (AUC) of 0.76 was achieved, which was 17% more sensitive when compared to age independently. For 30-d outcomes, the AUC increased to 0.89 when UEF physical and cognitive scores were included in the model with age and sex.

DISCUSSION

Sensor-based measures of physical and cognitive function enhance outcome prediction providing an objective practicable tool for risk stratification in emergency surgery settings among aging adults presenting with intra-abdominal symptoms.

Mortality After Elective Surgery: The Potential Role for Preoperative Palliative Care

BACKGROUND

Preoperative optimization is increasingly emphasized for high-risk surgical patients. One critical component of this includes preoperative advanced care planning to promote goal-concordant care. We aimed to define a subset of patients that might benefit from preoperative palliative care consult for advanced care planning.

MATERIALS AND METHODS

We examined adult patients admitted from January 2016 to December 2018 to a university health system for elective surgery. Multivariate logistic regression was used to identify variables associated with death within 1 y, and presence of palliative care consults preoperatively. Chi-square analysis evaluated the impact of a palliative care consult on advanced care planning variables.

RESULTS

Of the 29,132 inpatient elective procedures performed, there was a 2.0% mortality rate at 6 mo and 3.5% at 1 y. Those who died were more likely to be older, male, underweight (BMI <18), or have undergone an otolaryngology, neurosurgery or thoracic procedure type (all P-values < 0.05). At the time of admission, 29% had an advance directive, 90% had a documented code status, and 0.3% had a preoperative palliative care consult. Patients were more likely to have an advanced directive, a power of attorney, a documented code status, and have a do not resuscitate order if they had a palliative care consult (all P-values <0.05). The mortality rates and preoperative palliative care rates per procedure type did not follow similar trends.

CONCLUSIONS

Preoperative palliative care consultation before elective admissions for surgery had a significant impact on advanced care planning.

Guidelines for Perioperative Care for Emergency Laparotomy Enhanced Recovery After Surgery (ERAS) Society Recommendations: Part 1-Preoperative: Diagnosis, Rapid Assessment and Optimization

BACKGROUND

Enhanced Recovery After Surgery (ERAS) protocols reduce length of stay, complications and costs for a large number of elective surgical procedures. A similar, structured approach appears to improve outcomes, including mortality, for patients undergoing high-risk emergency general surgery, and specifically emergency laparotomy. These are the first consensus guidelines for optimal care of these patients using an ERAS approach.

METHODS

Experts in aspects of management of the high-risk and emergency general surgical patient were invited to contribute by the International ERAS® Society. Pubmed, Cochrane, Embase, and MEDLINE database searches on English language publications were performed for ERAS elements and relevant specific topics. Studies on each item were selected with particular attention to randomized controlled trials, systematic reviews, meta-analyses and large cohort studies, and reviewed and graded using the Grading of Recommendations, Assessment, Development and Evaluation (GRADE) system. Recommendations were made on the best level of evidence, or extrapolation from studies on non-emergency patients when appropriate. The Delphi method was used to validate final recommendations. The guideline has been divided into two parts: Part 1-Preoperative Care and Part 2-Intraoperative and Postoperative management. This paper provides guidelines for Part 1.

RESULTS

Twelve components of preoperative care were considered. Consensus was reached after three rounds.

CONCLUSIONS

These guidelines are based on the best available evidence for an ERAS approach to patients undergoing emergency laparotomy. Initial management is particularly important for patients with sepsis and physiological derangement. These guidelines should be used to improve outcomes for these high-risk patients.

Indications for Emergency Abdominal Surgeries in Older Patients: 7-Year Experience of a Single Centre

The majority of patients undergoing emergency laparotomy are older adults that carry the highest mortality. More research into the development of targeted interventions is required. Therefore, the aim of the study was to analyse the indications for emergency abdominal surgery in patients aged ≥ 65 admitted to the Department of General Surgery. The study included consecutive patients aged ≥ 65 who underwent emergency abdominal surgery within 48 h after admission at one institution. In 2010–2017, 986 patients were enrolled in the study (female 57%, male 43%). Patients were divided into three age groups, 65–70, 71–84 and ≥ 85, with 255 patients (25.9%), 562 patients (57.0%) and 169 patients (17.1%) in each group, respectively. In the first and second age groups, the most common indications for surgery were acute cholecystitis, non-malignant ileus, colorectal cancer complications and acute appendicitis. In the oldest patients, the most common indications were complications of colorectal cancer, acute cholecystitis, non-malignant ileus and complications of diverticulosis. In the women, the biggest differences in indications between age groups were colorectal cancer (p = 0.025) and peptic ulcer disease complications (p = 0.005); in the men, the biggest difference was seen for complicated diverticulitis (p = 0.001). The most frequent comorbidities were heart diseases (81.0%), followed by endocrine (33.6%) and vascular diseases (22.7%). The three most common indications for emergency surgery in older patients at our institution were acute cholecystitis, colorectal cancer complications and non-malignant bowel obstruction, affecting 59.5% of this group of patients. Elective surgery and endoscopic screening have the potential to prevent major part of these acute diseases. However, further prospective research is necessary on this field, particularly among frail, older patients.

Mortality and Health Care Utilization Among Medicare Patients Undergoing Emergency General Surgery vs Those With Acute Medical Conditions

Importance

Emergency general surgery (EGS) represents 11% of hospitalizations, and almost half of these hospitalized patients are older adults. Older adults have high rates of mortality and readmissions after EGS, yet little is known as to how these outcomes compare with acute medical conditions that have been targets for quality improvement.

Objective

To examine whether Medicare beneficiaries who undergo EGS experience similar 1-year outcomes compared with patients admitted with acute medical conditions.

Design, Setting, and Participants

This population-based, retrospective cohort study using Medicare claims data from January 1, 2008, to December 31, 2014, included adults 65 years or older with at least 1 year of Medicare claims who had urgent or emergency admissions for 1 of the 5 highest-burden EGS procedures (partial colectomy, small-bowel resection, peptic ulcer disease surgery, lysis of adhesions, or laparotomy) or a primary diagnosis of an acute medical condition (pneumonia, heart failure, or acute myocardial infarction). Patients undergoing EGS and those with acute medical conditions were matched 1:1 in a 2-step algorithm: (1) exact match by hospital or (2) propensity score match with age, sex, race/ethnicity, Charlson Comorbidity Index, individual comorbid conditions, claims-based frailty index, year of admission, and any intensive care unit stay. Data analysis was performed from July 16, 2018, to November 13, 2019.

Exposures

Partial colectomy, small-bowel resection, peptic ulcer disease surgery, lysis of adhesions, or laparotomy or a primary diagnosis pneumonia, heart failure, or acute myocardial infarction.

Main Outcomes and Measures

One-year mortality, postdischarge health care utilization (emergency department visit, additional hospitalization, intensive care unit stay, or total hospital encounters), and days at home during 1 year.

Results

A total of 481 417 matched pairs (mean [SD] age, 78.9 [7.8] years; 272 482 [56.6%] female) with adequate covariate balance were included in the study. Patients undergoing EGS experienced higher 30-day mortality (60 683 [12.6%] vs 56 713 [11.8%], P < .001) yet lower 1-year mortality (142 846 [29.7%] vs 158 385 [32.9%], P < .001) compared with medical patients. Among 409 363 pairs who survived discharge, medical patients experienced higher rates of total hospital encounters in the year after discharge (4 vs 3 per person-year; incidence rate ratio, 1.31; 95% CI, 1.30-1.32) but had similar mean days at home compared with patients undergoing EGS (293 vs 309 days; incident rate ratio, 1.004; 95% CI, 1.004-1.004).

Conclusions and Relevance

In this study, older patients undergoing EGS had similarly high 1-year rates of mortality, hospital use, and days away from home as acutely ill medical patients. These findings suggest that EGS should also be targeted for national quality improvement programs.

Effects of the intermediate care unit on the oldest-old general surgical patients: a retrospective, pre- and postintervention study

BACKGROUND

Whether the intermediate care unit (IMCU) is beneficial for the oldest-old (aged ≥ 80 years) general surgical patients still remains unknown. We aimed to investigate the impacts of IMCU on the clinical outcomes and cost in this population.

METHODS

A retrospective, pre- and postintervention study was performed in this population in a university teaching hospital. The primary outcome was the occurrence of life-threatening complications including death or unplanned ICU admission after the surgeries. Secondary outcomes included the comparisons of the hospitalization expenses, the hospital length of stay (LOS) and the postoperative LOS between the pre-IMCU group and the IMCU group.

RESULTS

Two hundred and seventeen patients were enrolled, including 98 in the pre-IMCU group and 119 in the IMCU group. After the introduction of IMCU, the occurrence of life-threatening complications significantly dropped from 11.2 to 2.5% (P = 0.012). The total hospitalization expenses showed a nonsignificant decreasing trend in the IMCU group (pre-IMCU group: 85856.3 ± 66583.7 RMB vs IMCU group: 78936.4 ± 36710.4 RMB). The treatment fee was much lower in the IMCU group (IMCU group: 4930.0 ± 4280.2 RMB vs pre-IMCU group: 7378.2 ± 10096.7 RMB, P = 0.017). Both the hospital LOS (IMCU group: 20.3 ± 10.3 days vs pre-IMCU group: 19.5 ± 9.0 days) and the postoperative hospital LOS (IMCU group: 12.0 ± 8.1 days vs pre-IMCU group: 11.2 ± 7.0 days) were not statistically different in the two groups.

CONCLUSIONS

The allocation of the oldest-old surgical patients who do not need organ support therapy in the ICU to IMCU rather than in the standard wards was associated with a significant decrease in postoperative life-threatening complications and treatment fee.

The Impact of Frailty on Long-Term Patient-Oriented Outcomes after Emergency General Surgery: A Retrospective Cohort Study

OBJECTIVES

Few studies examine the impact of frailty on long-term patient-oriented outcomes after emergency general surgery (EGS). We measured the prevalence of frailty among older EGS patients and examined the impact of frailty on 1-year outcomes.

DESIGN

Retrospective cohort study using 2008 to 2014 Medicare claims.

SETTING

Acute care hospitals.

PARTICIPANTS

Patients 65 years or older who received one of the five EGS procedures with the highest mortality burden (partial colectomy, small bowel resection, peptic ulcer disease repair, adhesiolysis, or laparotomy).

MEASUREMENTS

A validated claims-based frailty index (CFI) identified patients who were not frail (CFI < .15), pre-frail (.15 ≤ CFI < .25), mildly frail (.25 ≤ CFI < .35), and moderately to severely frail (CFI ≥ .35). Multivariable Cox regression compared 1-year mortality. Multivariable Poisson regression compared rates of post-discharge hospital encounters (hospitalizations, intensive care unit stay, emergency department visit) and home time over 1 year after discharge. All regression models adjusted for age, sex, race, admission from facility, procedure, sepsis, inpatient palliative care delivery, trauma center designation, hospital bed size, and teaching status, and they were clustered by patient and hospital referral region.

RESULTS

Among 468 459 older EGS adults, 37.4% were pre-frail, 12.4% were mildly frail, and 3.6% were moderately to severely frail. Patients with mild frailty experienced a higher risk of 1-year mortality compared with non-frail patients (hazard ratio = 1.97; confidence interval [CI] = 1.94-2.01). In the year after discharge, patients with mild and moderate to severe frailty had more hospital encounters compared with non-frail patients (7.8 and 11.5 vs 2.0 per person-year; incidence rate ratio [IRR] = 4.01; CI = 3.93-4.08 vs IRR = 5.89; CI = 5.70-6.09, respectively). Patients with mild and moderate to severe frailty also had fewer days at home in the year after discharge compared with non-frail patients (256 and 203 vs 302 mean days; IRR = .97; CI = .96-.97 vs IRR = .95; CI = .94-.95, respectively).

CONCLUSION

Older EGS patients with frailty are at increased risk for poor 1-year outcomes and decreased home time. Targeted interventions for older EGS patients with frailty during the index EGS hospitalization are urgently needed to improve long-term outcomes. J Am Geriatr Soc 68:1037-1043, 2020.

Defining Serious Illness Among Adult Surgical Patients

CONTEXT

Palliative care (PC) for seriously ill surgical patients, including aligning treatments with patients' goals and managing symptoms, is associated with improved patient-oriented outcomes and decreased health care utilization. However, efforts to integrate PC alongside restorative surgical care are limited by the lack of a consensus definition for serious illness in the perioperative context.

OBJECTIVES

The objectives of this study were to develop a serious illness definition for surgical patients and identify a denominator for quality measurement efforts.

METHODS

We developed a preliminary definition including a set of criteria for 11 conditions and health states. Using the RAND-UCLA Appropriateness Method, a 12-member expert advisory panel rated the criteria for each condition and health state twice, once after an in-person moderated discussion, for validity (primary outcome) and feasibility of measurement.

RESULTS

All panelists completed both rounds of rating. All 11 conditions and health states defining serious illness for surgical patients were rated as valid. During the in-person discussion, panelists refined and narrowed criteria for two conditions (vulnerable elder, heart failure). The final definition included the following 11 conditions and health states: vulnerable elder, heart failure, advanced cancer, oxygen-dependent pulmonary disease, cirrhosis, end-stage renal disease, dementia, critical trauma, frailty, nursing home residency, and American Society of Anesthesiology Risk Score IV-V.

CONCLUSION

We identified a consensus definition for serious illness in surgery. Opportunities remain in measuring the prevalence, identifying health trajectories, and developing screening criteria to integrate PC with restorative surgical care.

Racial/Ethnic Disparities in Longer-term Outcomes Among Emergency General Surgery Patients: The Unique Experience of Universally Insured Older Adults

OBJECTIVES

To determine whether racial/ethnic disparities in 30/90/180-day mortality, major morbidity, and unplanned readmissions exist among universally insured older adult (≥65 years) emergency general surgery patients; vary by diagnostic category; and can be explained by variations in geography, teaching status, age-cohort, and a hospital's percentage of minority patients.

SUMMARY OF BACKGROUND DATA

As the US population ages and discussions surrounding the optimal method of insurance provision increasingly enter into national debate, longer-term outcomes are of paramount concern. It remains unclear the extent to which insurance changes disparities throughout patients' postacute recovery period among older adults.

METHODS

Survival analysis of 2008 to 2014 Medicare data using risk-adjusted Cox proportional-hazards models.

RESULTS

A total of 6,779,649 older adults were included, of whom 82.8% identified as non-Hispanic white (NHW), 9.2% non-Hispanic black (NHB), 5.6% Hispanic, and 1.5% non-Hispanic Asian (NHA). Relative to NHW patients, each group of minority patients was significantly less likely to die [30-day NHB vs NHW hazard ratio (95% confidence interval): 0.88 (0.86-0.89)]. Differences became less apparent as outcomes approached 180 days [180-day NHB vs NHW: 1.00 (0.98-1.02)]. For major morbidity and unplanned readmission, differences among NHW, Hispanic, and NHA patients were comparable. NHB patients did consistently worse. Efforts to explain the occurrence found similar trends across diagnostic categories, but significant differences in disparities attributable to geography and the other included factors that combined accounted for up to 50% of readmission differences between racial/ethnic groups.

CONCLUSION

The study found an inversion of racial/ethnic mortality differences and mitigation of non-NHB morbidity/readmission differences among universally insured older adults that decreased with time. Persistent disparities among nonagenarian patients and hospitals managing a regionally large share of minority patients warrant particular concern.

Emergency Surgery for Obstructive Colon Cancer in Elderly Patients: Results of a Multicentric Cohort of the French National Surgical Association

BACKGROUND

Although elderly patients constitute most of the patients undergoing surgery for obstructed colon cancer, available data in the literature are very limited.

OBJECTIVE

The purpose of this study was to assess the management and outcomes of elderly patients treated for obstructed colon cancer.

DESIGN

This was a multicenter, retrospective cohort study.

SETTINGS

Between 2000 and 2015, 2325 patients managed for an obstructed colon cancer in member centers of the French National Surgical Association were identified. Data were collected by each center on a voluntary basis after institutional approval. Bowel obstruction was defined clinically and confirmed by imaging.

PATIENTS

Three age groups were defined, including patients <75 years, 75 to 84 years, and ≥85 years.

MAIN OUTCOME MEASURES

Postoperative and oncologic results in elderly patients with an obstructed colon cancer were measured. Relative survival was calculated as the ratio of the overall survival with the survival that would have been expected based on the corresponding general population.

INTERVENTIONS

A total of 302 patients (13%) underwent colonic stent insertion, and 1992 (87%) underwent surgery as emergency procedure.

RESULTS

A total of 2294 patients were analyzed (<75 y, n = 1200 (52%); 75-84 y, n = 650 (28%); and ≥85 y, n = 444 (20%)). Elderly patients were more likely to be women (p < 0.0001), to have proximal colon cancer (p < 0.0001), and to have a higher incidence of comorbidities (p < 0.0001). The use of colonic stent or the type of surgery was identical regardless of age. In patients with resected colon cancer, elderly patients had less stage IV disease (p < 0.0001). The absence of tumor resection (p < 0.0001) and definitive stoma rate increased with age (p < 0.0001). Postoperative mortality and morbidity were significantly higher in elderly patients (p < 0.0001), but surgical morbidity was similar across age groups (p = 0.60). Postoperative morbidity was correlated to the 6-month mortality rate in elderly (p < 0.0001). Overall and disease-free survivals were significantly lower in more elderly patients (p < 0.0001) but relative survival was not (p = 0.09).

LIMITATIONS

It is quite difficult to know how to interpret these data as a whole, given the inherent bias in the study population, lack of ability to stratify by performance status, and long study period duration.

CONCLUSIONS

Elderly patients have high morbidity with lower survival in the highest age ranges of elderly subgroups. These data should be considered when deciding on an operative approach. See Video Abstract at http://links.lww.com/DCR/A964.

Central venous oxygen saturation/lactate ratio: a novel predictor of outcome following emergency open laparotomy

INTRODUCTION

Emergency laparotomy is associated with high rates of morbidity and mortality. The need for highly sensitive readily prognostic biomarkers is necessary to improve the outcome. We investigated the usefulness of post-operative arterial lactate and ScvO₂/lactate ratio as predictors of outcome after post-operative emergency open laparotomy. To the best of our knowledge, the novel ScvO₂/lactate ratio was not investigated before in emergency open laparotomy patients.

METHODS

It is a prospective observational cohort study. We investigated the usefulness of post-operative arterial lactate and ScvO₂/lactate ratio as predictors of early mortality in 40 patients following emergency open laparotomy admitted to the ICU.

RESULTS

Admission and 24 h lactate levels were predictor of mortality with cut-off point > 3.95 mmol/L, sensitivity 100%, and specificity 93.3%, and cut-off > 3.5 mmol/L, sensitivity 100%, and specificity 96.7%, respectively. In this study, ScvO₂/lactate ratio on admission was predictor of at day 7 with cut-off point < 13.95, sensitivity 100%, and specificity 96.7% p < 0.0001. Lactate at 12 and 24 h was also predictor of survival p < 0.0001. Serial arterial lactate was highly correlated to ICU length of stay; admission APACHE II and day 1; and 2 MODS and SOFA scores (p < 0.001).

CONCLUSION

Serial blood lactate as well as the novel ScvO₂/lactate ratio can be useful for early predictors of mortality at 7 days. Serial lactate levels correlate to admission ICU scores APACHE II; MODS and SOFA in post-operative emergency open laparotomy patients.

Loss of Community-Dwelling Status Among Survivors of High-Acuity Emergency General Surgery Disease

OBJECTIVES

To examine loss of community-dwelling status 9 months after hospitalization for high-acuity emergency general surgery (HA-EGS) disease among older Americans.

DESIGN

Retrospective analysis of claims data.

SETTING

US communities with Medicare beneficiaries.

PARTICIPANTS

Medicare beneficiaries age 65 years or older hospitalized urgently/emergently between January 1, 2015, and March 31, 2015, with a principal diagnosis representing potential life or organ threat (necrotizing soft tissue infections, hernias with gangrene, ischemic enteritis, perforated viscus, toxic colitis or gastroenteritis, peritonitis, intra-abdominal hemorrhage) and an operation of interest on hospital days 1 or 2 (N = 3319).

MEASUREMENTS

Demographic characteristics (age, race, and sex), comorbidities, principal diagnosis, complications, and index hospitalization disposition (died; discharged to skilled nursing facility [SNF], long-term acute care [LTAC], rehabilitation, hospice, home (with or without services), or acute care hospital; other) were measured. Survivors of index hospitalization were followed until December 31, 2015, on mortality and community-dwelling status (SNF/LTAC vs not). Descriptive statistics, Kaplan-Meier plots, and χ² tests were used to describe and compare the cohort based on disposition. A multivariable logistic regression model, adjusted for age, sex, comorbidities, complications, and discharge disposition, determined independent predictors of loss of community-dwelling status at 9 months.

RESULTS

A total of 2922 (88%) survived index hospitalization. Likelihood of discharge to home decreased with increasing age, baseline comorbidities, and in-hospital complications. Overall, 418 (14.3%) HA-EGS survivors died during the follow-up period. Among those alive at 9 months, 10.3% were no longer community dwelling. Initial discharge disposition to any location other than home and three or more surgical complications during index hospitalization were independent predictors of residing in a SNF/LTAC 9 months after surviving HA-EGS.

CONCLUSION

Older Americans, known to prioritize living in the community, will experience substantial loss of independence due to HA-EGS. Long-term expectations after surviving HA-EGS must be framed from the perspective of the outcomes that older patients value the most. Further research is needed to examine the quality-of-life burden of EGS survivorship prospectively. J Am Geriatr Soc 67:2289-2297, 2019.

High-Risk Comorbidity Combinations in Older Patients Undergoing Emergency General Surgery

BACKGROUND/OBJECTIVES

Over a million older patients in the United States are admitted yearly for emergency general surgery (EGS) conditions. Seven procedure types dominate: colon, small bowel, gallbladder, ulcer disease, adhesiolysis, appendix, and laparotomy operations. A higher comorbidity burden is known to increase mortality in this population, but the impact of specific comorbidity combinations is unknown. Our objectives were to (1) characterize the distribution of procedures, comorbidities, and outcomes for older patients undergoing EGS; and (2) apply a data-driven approach (association rule mining) to identify comorbidity combinations associated with disproportionately high mortality.

DESIGN, SETTING, AND PARTICIPANTS

Cross-sectional study of patients 65 years and older who underwent one of the seven procedures previously cited, taken from the 2011 Nationwide Inpatient Sample. A total of 280 885 patient encounters were identified.

MEASUREMENTS

In-hospital mortality, procedures, and comorbidities based on the Elixhauser Comorbidity Index.

RESULTS

Overall mortality was 5.6%. The most common procedures were gallbladder (33.7%), ulcer surgery (21.5%), and adhesiolysis (21.0%). Mortality increased for all procedures as patients aged. Comorbidities associated with the highest mortality included coagulopathy (adjusted odds ratio [aOR] = 3.74; 95% confidence interval [CI] = 3.41-4.11; p < .001), fluid and electrolyte disorders (FED) (aOR = 2.89; 95% CI = 3.66-3.14; p < .001), and liver disease (aOR = 1.89; 95% CI = 1.61-2.22; p < .001). Three-way comorbidity combinations most highly associated with mortality were coagulopathy, FED, and peripheral vascular disease (aOR = 5.10; 95% CI = 4.17-6.24; p < .001), and coagulopathy, FED, and chronic pulmonary disease (aOR = 4.83; 95% CI = 4.00-5.82; p < .001).

CONCLUSION

For older patients, combinations of comorbidities portend additional risk beyond single comorbidities, and the associated risk burden is driven by the specific constellation of comorbidities present. Future work must continue to examine the effect of co-occurring diseases to provide personalized and realistic prognostication for older patients undergoing EGS. J Am Geriatr Soc 67:503-510, 2019.

A practical risk scale for predicting morbidity and mortality in the emergency general surgical setting: A prospective multi-center study

BACKGROUND

Low albumin is a prognostic factor associated with poor surgical outcomes. We aimed to examine the predicative ability of easily obtainable point-of-care variables in combination, to derive a practical risk scale for predicting older adults at risk of poor outcomes on admission to the emergency general surgical setting.

METHODS

This is an international multi-center prospective cohort study conducted as part of the Older Persons Surgical Outcomes Collaboration (www.OPSOC.eu). The effect of having hypoalbuminemia (defined as albumin ≤3.5 g/dL) on selected outcomes was examined using fully adjusted multivariable models. In a subgroup of patients with hypoalbuminemia, we observed four risk characteristics (Male, Anemia, Low albumin, Eighty-five and over [MALE]). Subsequently, the impact of incremental increase in MALE score (each characteristic scoring 1 point (maximum score 4) on measured outcomes was assessed.

RESULTS

The cohort consisted of 1406 older patients with median (IQR) age of 76 (70-83) years. In fully adjusted models, hypoalbuminemia was significantly associated with undergoing emergency surgery (1.32 (95%CI 1.03-1.70); p = 0.03), 30-day mortality (4.23 (2.22-8.08); p < 0.001), 90-day mortality (3.36 (2.14-5.28); p < 0.001) (primary outcome), and increased hospital length of stay, irrespective of whether a patient received emergency surgical intervention. Every point increase in MALE score was associated with higher odds of mortality, with a MALE score of 4 being associated with 30-day mortality (adjusted OR(95% CI) = 33.38 (3.86-288.7); p = 0.001) and 90-day mortality (11.37 (3.85-33.59); p < 0.001) compared to the reference category of those with MALE score 0.

CONCLUSIONS

The easy to use and practical MALE risk score calculated at point of care identifies older adults at a greater risk of poor outcomes, thereby allowing clinicians to prioritize patients who may benefit from early comprehensive geriatric assessment in the emergency general surgical setting.

High Burden of Palliative Care Needs of Older Adults During Emergency Major Abdominal Surgery

OBJECTIVES

To quantify preoperative illness burden in older adults undergoing emergency major abdominal surgery (EMAS), to examine the association between illness burden and postoperative outcomes, and to describe end-of-life care in the year after discharge.

DESIGN

Retrospective study using data from Health and Retirement Study interviews linked to Medicare claims (2000-2012).

SETTING

National population-based dataset.

PARTICIPANTS

Medicare beneficiaries who underwent EMAS.

MEASUREMENTS

High illness burden, defined as ≥2 of the following vulnerabilities: functional dependence, dementia, use of helpers, multimorbidity, poor prognosis, high healthcare utilization. In-hospital outcomes were complications and mortality. Postdischarge outcomes included emergency department (ED) visits, hospitalization, intensive care unit (ICU) stay, and 365-day mortality. For individuals discharged alive who died within 365 days of surgery, outcomes included hospice use, hospitalization, ICU use, and ED use in the last 30 days of life. Multivariable regression was used to determine the association between illness burden and outcomes.

RESULTS

Of 411 participants, 57% had high illness burden. More individuals with high illness burden had complications (45% vs 28% p=0.00) and in-hospital death (20% vs 9%, p=0.00) than those without. After discharge (n=349), individuals with high illness burden experienced more ED visits (57% vs 46%, P=.04) and were more likely to die (35% vs 13%, p=0.00). Of those who died after discharge (n=86), 75% had high illness burden, median survival was 67 days (range 21-141 days), 48% enrolled in hospice, 32% died in the hospital, 23% were in the ICU in the last 30 days of life and 37% had an ED visit in the last 30 days of life.

CONCLUSION

Most older adults undergoing EMAS have preexisting high illness burden and experience high mortality and healthcare use in the year after surgery, particularly near the end of life. Concurrent surgical and palliative care may improve quality of life and end-of-life care in these people. J Am Geriatr Soc 66:2072-2078, 2018.

Sarcopenia increases risk of long-term mortality in elderly patients undergoing emergency abdominal surgery

BACKGROUND

Frailty is associated with poor surgical outcomes in elderly patients but is difficult to measure in the emergency setting. Sarcopenia, or the loss of lean muscle mass, is a surrogate for frailty and can be measured using cross-sectional imaging. We sought to determine the impact of sarcopenia on 1-year mortality after emergency abdominal surgery in elderly patients.

METHODS

Sarcopenia was assessed in patients 70 years or older who underwent emergency abdominal surgery at a single hospital from 2006 to 2011. Average bilateral psoas muscle cross-sectional area at L3, normalized for height (Total Psoas Index [TPI]), was calculated using computed tomography. Sarcopenia was defined as TPI in the lowest sex-specific quartile. Primary outcome was mortality at 1 year. Secondary outcomes were in-hospital mortality and mortality at 30, 90, and 180 days. The association of sarcopenia with mortality was assessed using Cox proportional hazards regression and model performance judged using Harrell's C-statistic.

RESULTS

Two hundred ninety-seven of 390 emergency abdominal surgery patients had preoperative imaging and height. The median age was 79 years, and 1-year mortality was 32%. Sarcopenic and nonsarcopenic patients were comparable in age, sex, race, comorbidities, American Society of Anesthesiologists classification, procedure urgency and type, operative severity, and need for discharge to a nursing facility. Sarcopenic patients had lower body mass index, greater need for intensive care, and longer hospital length of stay (p < 0.05). Sarcopenia was independently associated with increased in-hospital mortality (risk ratio, 2.6; 95% confidence interval [CI], 1.6-3.7) and mortality at 30 days (hazard ratio [HR], 3.7; 95% CI, 1.9-7.4), 90 days (HR, 3.3; 95% CI, 1.8-6.0), 180 days (HR, 2.5; 95% CI, 1.4-4.4), and 1 year (HR, 2.4; 95% CI, 1.4-3.9).

CONCLUSION

Sarcopenia is associated with increased risk of mortality over 1 year in elderly patients undergoing emergency abdominal surgery. Sarcopenia defined by TPI is a simple and objective measure of frailty that identifies vulnerable patients for improved preoperative counseling, setting realistic goals of care, and consideration of less invasive approaches.

Outcomes and palliative care utilization in patients with dementia and acute abdominal emergency: opportunities for surgical quality improvement

BACKGROUND

When patients with dementia develop acute surgical abdomen, patients, surrogates, and surgeons need accurate prognostic information to facilitate goal-concordant decision making. Palliative care can assist with communication, symptom management, and family and caregiver support in this population. We aimed to characterize outcomes and patterns of palliative care utilization among patients with dementia, presenting with abdominal surgical emergency.

METHOD

We retrospectively queried the National Inpatient Sample for patients aged >50 years with dementia and acute abdominal emergency who were admitted nonelectively 2009-2013, utilizing ICD-9-CM codes for dementia and surgical indication. We characterized outcomes and identified predictors of palliative care utilization.

RESULTS

Among 15,209 patients, in-hospital mortality was 10.2%, the nonroutine discharge rate was 67.2%, and 7.5% received palliative care. Patients treated operatively were less likely to receive palliative care than those who did not undergo operation (adjusted OR = 0.50; 95% CI 0.41-0.62). Only 6.4% of patients discharged nonroutinely received palliative care.

CONCLUSION

Patients with dementia and acute abdominal emergency have considerable in-hospital mortality, a high frequency of nonroutine discharge, and low palliative care utilization. In this group, we discovered a large gap in palliative care utilization, particularly among those treated operatively and those who are discharged nonroutinely.

A Framework to Improve Surgeon Communication in High-Stakes Surgical Decisions: Best Case/Worst Case

Importance

Although many older adults prefer to avoid burdensome interventions with limited ability to preserve their functional status, aggressive treatments, including surgery, are common near the end of life. Shared decision making is critical to achieve value-concordant treatment decisions and minimize unwanted care. However, communication in the acute inpatient setting is challenging.

Objective

To evaluate the proof of concept of an intervention to teach surgeons to use the Best Case/Worst Case framework as a strategy to change surgeon communication and promote shared decision making during high-stakes surgical decisions.

Design, Setting, and Participants

Our prospective pre-post study was conducted from June 2014 to August 2015, and data were analyzed using a mixed methods approach. The data were drawn from decision-making conversations between 32 older inpatients with an acute nonemergent surgical problem, 30 family members, and 25 surgeons at 1 tertiary care hospital in Madison, Wisconsin.

Interventions

A 2-hour training session to teach each study-enrolled surgeon to use the Best Case/Worst Case communication framework.

Main Outcomes and Measures

We scored conversation transcripts using OPTION 5, an observer measure of shared decision making, and used qualitative content analysis to characterize patterns in conversation structure, description of outcomes, and deliberation over treatment alternatives.

Results

The study participants were patients aged 68 to 95 years (n = 32), 44% of whom had 5 or more comorbid conditions; family members of patients (n = 30); and surgeons (n = 17). The median OPTION 5 score improved from 41 preintervention (interquartile range, 26-66) to 74 after Best Case/Worst Case training (interquartile range, 60-81). Before training, surgeons described the patient's problem in conjunction with an operative solution, directed deliberation over options, listed discrete procedural risks, and did not integrate preferences into a treatment recommendation. After training, surgeons using Best Case/Worst Case clearly presented a choice between treatments, described a range of postoperative trajectories including functional decline, and involved patients and families in deliberation.

Conclusions and Relevance

Using the Best Case/Worst Case framework changed surgeon communication by shifting the focus of decision-making conversations from an isolated surgical problem to a discussion about treatment alternatives and outcomes. This intervention can help surgeons structure challenging conversations to promote shared decision making in the acute setting.

The Need to Consider Longer-term Outcomes of Care: Racial/Ethnic Disparities Among Adult and Older Adult Emergency General Surgery Patients at 30, 90, and 180 Days

OBJECTIVES

Following calls from the National Institutes of Health and American College of Surgeons for "urgently needed" research, the objectives of the present study were to (1) ascertain whether differences in 30/90/180-day mortality, major morbidity, and unplanned readmissions exist among adult (18-64 yr) and older adult (≥65 yr) emergency general surgery (EGS) patients; (2) vary by diagnostic category; and (3) are explained by variations in insurance, income, teaching status, hospital EGS volume, and a hospital's proportion of minority patients.

BACKGROUND

Racial/ethnic disparities have been described in in-hospital and 30-day settings. How longer-term outcomes compare-a critical consideration for the lived experience of patients-has, however, only been limitedly considered.

METHODS

Survival analysis of 2007 to 2011 California State Inpatient Database using Cox proportional hazards models.

RESULTS

A total of 737,092 adults and 552,845 older adults were included. In both cohorts, significant differences in 30/90/180-day mortality, major morbidity, and unplanned readmissions were found, pointing to persistently worse outcomes between non-Hispanic Black and White patients [180-d readmission hazard ratio (95% confidence interval):1.04 (1.03-1.06)] and paradoxically better outcomes among Hispanic adults [0.85 (0.84-0.86)] that were not encountered among Hispanic older adults [1.06 (1.04-1.07)]. Stratified results demonstrated robust morbidity and readmission trends between non-Hispanic Black and White patients for the majority of diagnostic categories, whereas variations in insurance/income/teaching status/EGS volume/proportion of minority patients all significantly altered the effect-combined accounting for up to 80% of risk-adjusted differences between racial/ethnic groups.

CONCLUSIONS

Racial/ethnic disparities exist in longer-term outcomes of EGS patients and are, in part, determined by differences in factors associated with emergency care. Efforts such as these are needed to understand the interplay of influences-both in-hospital and during the equally critical, postacute phase-that underlie disparities' occurrence among surgical patients.

Utility of the "Surprise" Question in Predicting Survival among Older Patients with Acute Surgical Conditions

BACKGROUND

The surprise question is a validated tool for identifying patients with increased risk of death within one year who could, therefore, benefit from palliative care. However, its utility in surgery is unknown.

OBJECTIVE

We sought to determine whether the surprise question predicted 12-month mortality in older emergency general surgery patients.

DESIGN

This was a prospective cohort study.

SETTING/SUBJECTS

Emergency general surgery attendings and surgical residents in or beyond their third year of training at a single tertiary care academic hospital from January to July 2014.

MEASUREMENTS

Surgeons responded to the surprise question within 72 hours of evaluating patients, ≥65 years, hospitalized with an acute surgical condition. Patient data, including demographic and clinical characteristics, were extracted from the medical record. Mortality within 12 months of initial evaluation was determined by using Social Security death data.

RESULTS

Ten attending surgeons and 18 surgical residents provided 163 responses to the surprise question for 119 patients: 60% of responses were "No, I would not be surprised" and 40% were "Yes, I would be surprised." A "No" response was associated with increased odds of death within 12 months in binary logistic regression (OR 4.8 [95% CI 2.1-11.1]).

CONCLUSIONS

The surprise question is a valuable tool for identifying older patients with higher risk of death, and it may be a useful screening criterion for older emergency general surgery patients who would benefit from palliative care evaluation.

Preoperative assessment of surgical risk: creation of a scoring tool to estimate 1-year mortality after emergency abdominal surgery in the elderly patient

BACKGROUND

The risk of mortality after emergency general surgery (EGS) in elderly patients is prolonged beyond initial hospitalization. Our objective was to develop a preoperative scoring tool to quantify risk of 1-year mortality.

METHODS

Three hundred ninety EGS patients aged 70 years or more were analyzed. Risk factors for 1-year mortality were identified using stepwise-forward logistic multivariate regression and weights assigned using natural logarithm of odds ratios. A geriatric emergency surgery mortality (GEM) score was derived from the aggregate of weighted scores. Leave-one-out cross-validation was performed.

RESULTS

One-year mortality was 32%. Risk factors and their weights were: acute kidney injury (2), American Society of Anesthesiology class greater than or equal to 4 (2), Charlson Comorbidity Index greater than or equal to 4 (1), albumin less than 3.5 mg/dL (1), and body mass index (less than 18.5 kg/m² [1]; 18.5 to 29.9 kg/m² [0]; ≥30 kg/m² [-1]). One-year mortality was: GEM 0 to 1 (0% to 7%); GEM 2 to 5 (32% to 68%); GEM 6 to 8 (94% to 100%). C-statistics were .82 and .75 in training and validation data sets, respectively.

CONCLUSIONS

A simple score using 5 clinical variables predicts 1-year mortality after EGS with reasonable accuracy and assists in preoperative counseling.
