General surgeon involvement in the care of patients designated with an American Association for the Surgery of Trauma-endorsed ICD-10-CM emergency general surgery diagnosis code in Wisconsin.
The authors sought to: (1) translate previously-developed ICD-9-CM diagnosis codes representing emergency general surgery (EGS) conditions to ICD-10-CM codes and (2) determine the national burden of and assess surgeon involvement across EGS conditions. They found that, of the seven most common EGS diagnoses, surgeon involvement was highest for appendicitis and biliary tract disease. For the other five most common conditions, surgeons were involved in roughly 20% of patient care episodes.

Hospital location and socioeconomic disadvantage of emergency general surgery patients.
This study’s purpose was to test the hypothesis that a hospital’s neighborhood disadvantage is associated with vulnerability of its emergency general surgery (EGS) patients. An area deprivation index (ADI), which is a neighborhood-level measure of disadvantage, and key characteristics of 724 hospitals in 14 states were linked to patient-level data in State Inpatient Databases. Hospitals in more disadvantaged areas disproportionately serve underserved EGS patient populations but are less likely to have robust resources for EGS care or train future EGS surgeons.

The association between self-declared acute care surgery services and critical care resources: results from a national survey.
In this study, the investigators examined differences in critical care structures and processes between hospitals with Acute Care Surgery (ACS) versus general surgeon on call (GSOC) models for emergency general surgery (EGS) care. The investigators concluded that while harnessing of critical care structures and processes varied across hospitals that had implemented ACS, overall ACS models of care appeared to have more robust critical care practices.

Identifying the fundamental structures and processes of care contributing to emergency general surgery quality using a mixed-methods Donabedian approach.
Acute Care Surgery (ACS) was developed as a structured, team-based approach to providing round-the-clock emergency general surgery (EGS) care for adult patients needing treatment for diseases such as cholecystitis, gastrointestinal perforation, and necrotizing fasciitis. In this study, the investigators sought to use a Donabedian approach to elucidate potential EGS structures and processes that might be associated with improved outcomes as an initial step in designing the optimal model of acute care surgery care for EGS patients.

Delay in emergency hernia surgery is associated with worse outcomes.
The purpose of this study was to determine if the variation in timing of urgent surgery impacts surgical outcomes. The National Surgical Quality Improvement Program (NSQIP) database was searched for emergent surgeries in 2011-2016 for abdominal hernia resulting in obstruction or gangrene by primary post-op diagnosis. Findings showed that delayed surgery was associated with increased rates of major complications, longer operative times, longer postoperative lengths of stay, increased re-operations, increased readmissions, and increased 30-day mortality. Next-day surgery and surgery delayed more than one day were associated with increased odds of a major complication.

Hospital variation in gastrostomy tube use among the critically ill.
This article describes an analysis of hospital variation in gastrostomy tube use among critically ill patients in hospitals. The investigators used the AHRQ National Inpatient Sample Database from 2014. They identified hospitalized patients using ICD-9, Clinical Modification codes consistent with critical illness who received gastrostomy tubes. Overall, the median rate was 2.0 per 100 critically ill patients with no variation between hospital size.

Gastrostomy tube use in the critically ill, 1994-2014.
This study used AHRQ’s Healthcare Cost and Utilization Project’s (HCUP’s) National Inpatient Sample to evaluate trends in gastrostomy tube use among critically ill adults from 1994 to 2014. Patients with dementia were excluded from the study. It was found that tube use more than doubled during that time period. Most patients were discharged to long-term care facilities after tube placement. Population-based rates went from 11.9 to 28.8 gastrostomies per 100,000 adults which is an increase of 142%.

High burden of palliative care needs of older adults during emergency major abdominal surgery.
The purpose of this retrospective study was 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. The investigators found that 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.

Geographic diffusion and implementation of acute care surgery: an uneven solution to the national emergency general surgery crisis.
Researchers investigated geographic diffusion of acute care surgery (ACS) models of care and characterized the communities in which ACS implementation is lagging. They found that acute care surgery implementation has not been uniform. Rural regions have limited ACS access, with hospitals in counties with greater than the 75th percentile population having 5.4 times higher odds of implementing ACS than hospitals in counties with less than 25th percentile population.

Innovation or rebranding, acute care surgery diffusion will continue.
The researchers conducted a qualitative study comprising face-to-face interviews with senior surgeons responsible for acute care surgery (ACS) at 18 teaching hospitals chosen to ensure diversity of opinions and practice environment. Their analysis suggests that the implementation of ACS, whether a true health care delivery innovation or an innovative rebranding, fits into the Rogers’ diffusion of innovation theory.

Time to appendectomy and risk of perforation in acute appendicitis.
This study sought to determine whether there is an association between time and perforation after acute appendicitis patients arrive at the hospital. Using data on 7,505 patients treated at 52 hospitals, they found that there was no association between perforation and in-hospital time prior to surgery among adults treated with appendectomy.

Transfer rates and use of post-acute care after surgery at critical access vs non-critical access hospitals.
This study evaluated discharge practice patterns and use of post-acute care after surgical admissions at critical access hospitals (CAHs). It found that for each of six common surgical procedures, a greater proportion of patients was transferred to another hospital. However, the proportion of patients at CAHs using post-acute care is equal to or less than that of patients treated in non-CAHs.
