ECLAPTE: Effective Closure of LAParoTomy in Emergency-2023 World Society of Emergency Surgery guidelines for the closure of laparotomy in emergency settings

Laparotomy incisions provide easy and rapid access to the peritoneal cavity in case of emergency surgery. Incisional hernia (IH) is a late manifestation of the failure of abdominal wall closure and represents frequent complication of any abdominal incision: IHs can cause pain and discomfort to the patients but also clinical serious sequelae like bowel obstruction, incarceration, strangulation, and necessity of reoperation. Previous guidelines and indications in the literature consider elective settings and evidence about laparotomy closure in emergency settings is lacking. This paper aims to present the World Society of Emergency Surgery (WSES) project called ECLAPTE (Effective Closure of LAParoTomy in Emergency): the final manuscript includes guidelines on the closure of emergency laparotomy.

Acute mesenteric ischemia: updated guidelines of the World Society of Emergency Surgery

Acute mesenteric ischemia (AMI) is a group of diseases characterized by an interruption of the blood supply to varying portions of the intestine, leading to ischemia and secondary inflammatory changes. If untreated, this process may progress to life-threatening intestinal necrosis. The incidence is low, estimated at 0.09-0.2% of all acute surgical admissions, but increases with age. Although the entity is an uncommon cause of abdominal pain, diligence is required because if untreated, mortality remains in the range of 50%. Early diagnosis and timely surgical intervention are the cornerstones of modern treatment to reduce the high mortality associated with this entity. The advent of endovascular approaches in parallel with modern imaging techniques is evolving and provides new treatment options. Lastly, a focused multidisciplinary approach based on early diagnosis and individualized treatment is essential. Thus, we believe that updated guidelines from World Society of Emergency Surgery are warranted, in order to provide the most recent and practical recommendations for diagnosis and treatment of AMI.

SCORE - Leveling the Playing Field for Surgical Training Programs

OBJECTIVE

The Surgical Council on Resident Education (SCORE) web portal provides a uniform, comprehensive, competency-based curriculum for general surgery residents. One of SCORE's principal founding goals was to provide equal opportunity for access of educational resources at programs across the United States which reported having a range of resources. We aimed to determine if there was a difference in portal usage by trainees in independent versus university programs, and across geographic areas.

METHODS

Using analytic software, we measured SCORE usage by trainees in 246 subscribing programs from August 2015 to March 2017. The primary outcome was the average duration of SCORE use per login. Secondary outcomes were the geographic region of each program, and university versus independent designation. Encounters lasting >8 hours (comprising 7% of the data set) were excluded to eliminate the likelihood of failure to log off the portal.

RESULTS

Over the study period, there were 669,501 SCORE sessions with 22% of these lasting 1 to 5 minutes, 33% lasting 6 to 30 minutes, and 28% lasting 31 to 120 minutes. Between the university (64.4% of encounters) and independent (35.6% of encounters) program types, there was no significant difference in average visit length overall, or in the normally-distributed designated time categories (t test -1.0, p = 0.3). When mean encounter length per program was compared by geographic regions, there was also no difference in the three time categories (ANOVA p = 0.9, 0.2, and 0.5, respectively).

CONCLUSIONS

Most (50%) of SCORE encounters lasted 30 minutes of less, confirming prior work that shows trainees use the portal in relatively short bursts of activity. While there were more encounters from university program trainees (proportional with their greater numbers), the mean duration of an individual encounter did not significantly differ by program type as a whole or by region. These results suggest that SCORE is an equally accessible educational resource and is used by surgical trainees, regardless of program type or geographic region.

Best Practice for Implementation of the SCORE Portal in General Surgery Residency Training Programs

INTRODUCTION

The Surgical Council on Resident Education (SCORE) has presented a workshop annually at the annual meeting of the Association of Program Directors (APDS) to discuss the evolution of the SCORE portal and best practices for implementation within residency training programs.

METHODS/RESULTS

A review of the literature was undertaken, along with a summation of discussion at these several workshops. A history of the SCORE project and a summary of its organizational framework and content are presented. In addition, best practices for use of SCORE within programs are described.

CONCLUSIONS

The SCORE portal is now a decade old, and is used ubiquitously in US surgical training programs. With this experience, there is data to show the utility of SCORE to support trainee learning and programmatic didactics.

Association Between Maintaining Certification in General Surgery and Loss-of-License Actions

This study uses American Board of Surgery data to assess the association between maintainence of certification in general surgery and loss-of-license actions after expiration of the initial 10-year certification among general surgeons.

What Can SCORE Web Portal Usage Analytics Tell Us About How Surgical Residents Learn?

PURPOSE

The Surgical Council on Resident Education (SCORE) was established in 2004 with 2 goals: to develop a standardized, competency-based curriculum for general surgery residency training; and to develop a web portal to deliver this content. By 2012, 96% of general surgery residency programs subscribed to the SCORE web portal. Surgical educators have previously described the myriad ways they have incorporated SCORE into their curricula. The aim of this study was to analyze user data to describe how and when residents use SCORE.

METHODS

Using analytic software, we measured SCORE usage from July, 2013 to June, 2016. Data such as IP addresses, geo-tagging coordinates, and operating system platforms were collected. The primary outcome was the median duration of SCORE use. Secondary outcomes were the time of day and the operating system used when accessing SCORE. Descriptive statistics were performed, and a p < 0.05 was deemed statistically significant.

RESULTS

There were 42,743 total SCORE subscribers during the study period (75% resident and 25% faculty) with a mean of 14,248 subscribers per year. The overall median duration of SCORE use was 11.9minute/session (interquartile range [IQR]: 6.8). Additionally, there was a significant increase in session length over the 3 academic years; 10.1 (IQR: 6.4), 11.9 (IQR: 7.2), and 13.2minute/session (IQR: 5.4) in 2013 to 2014, 2014 to 2015, and 2015 to 2016, respectively (p < 0.001). SCORE usage was highest in November to February at 21.0minute/session (14.2) compared to July to October and March to June (12.3 [IQR: 3.2] and 9.6minute/session [IQR: 2.2]), respectively (p < 0.001). This seasonal trend continued for all 3 years. We observed an increased number of sessions per day over the 3 years: median of 1500 sessions/d (IQR: 1115) vs 1706 (IQR: 1334) vs 1728 (IQR: 1352), p < 0.001. (Fig.). Most SCORE sessions occurred at night: 38,011 (IQR: 4532) vs 17,529 (IQR: 19,850) during the day (p < 0.001). Windows was the most frequently used operating system at 48.9% (p < 0.001 vs others).

CONCLUSIONS

SCORE usage has increased significantly over the last 3 years, when measured by number of sessions per day and length of time per session. There are predictable daily, diurnal, and seasonal variations in SCORE usage. The annual in-training examination is a prominent factor stimulating SCORE usage.

Proceedings of resources for optimal care of acute care and emergency surgery consensus summit Donegal Ireland

BACKGROUND

Opportunities to improve emergency surgery outcomes exist through guided better practice and reduced variability. Few attempts have been made to define optimal care in emergency surgery, and few clinically derived key performance indicators (KPIs) have been published. A summit was therefore convened to look at resources for optimal care of emergency surgery. The aim of the Donegal Summit was to set a platform in place to develop guidelines and KPIs in emergency surgery.

METHODS

The project had multidisciplinary global involvement in producing consensus statements regarding emergency surgery care in key areas, and to assess feasibility of producing KPIs that could be used to monitor process and outcome of care in the future.

RESULTS

Forty-four key opinion leaders in emergency surgery, across 7 disciplines from 17 countries, composed evidence-based position papers on 14 key areas of emergency surgery and 112 KPIs in 20 acute conditions or emergency systems.

CONCLUSIONS

The summit was successful in achieving position papers and KPIs in emergency surgery. While position papers were limited by non-graded evidence and non-validated KPIs, the process set a foundation for the future advancement of emergency surgery.

General surgery resident rotations in surgical critical care, trauma, and burns: what is optimal for residency training?

BACKGROUND

There are no specific Accreditation Council for Graduate Medical Education General Surgery Residency Program Requirements for rotations in surgical critical care (SCC), trauma, and burn. We sought to determine the experience of general surgery residents in SCC, trauma, and burn rotations.

METHODS

Data analysis of surgical rotations of American Board of Surgery general surgery resident applicants (n = 7,299) for the last 8 years (2006 to 2013, inclusive) was performed through electronic applications to the American Board of Surgery Qualifying Examination. Duration (months) spent in SCC, trauma, and burn rotations, and postgraduate year (PGY) level were examined.

RESULTS

The total months in SCC, trauma and burn rotations was mean 10.2 and median 10.0 (SD 3.9 months), representing approximately 16.7% (10 of 60 months) of a general surgery resident's training. However, there was great variability (range 0 to 29 months). SCC rotation duration was mean 3.1 and median 3.0 months (SD 2, min to max: 0 to 15), trauma rotation duration was mean 6.3 and median 6.0 months (SD 3.5, min to max: 0 to 24), and burn rotation duration was mean 0.8 and median 1.0 months (SD 1.0, min to max: 0 to 6). Of the total mean 10.2 months duration, the longest exposure was 2 months as PGY-1, 3.4 months as PGY-2, 1.9 months as PGY-3, 2.2 months as PGY-4 and 1.1 months as PGY-5. PGY-5 residents spent a mean of 1 month in SCC, trauma, and burn rotations. PGY-4/5 residents spent the majority of this total time in trauma rotations, whereas junior residents (PGY-1 to 3) in SCC and trauma rotations.

CONCLUSIONS

There is significant variability in total duration of SCC, trauma, and burn rotations and PGY level in US general surgery residency programs, which may result in significant variability in the fund of knowledge and clinical experience of the trainee completing general surgery residency training. As acute care surgery programs have begun to integrate emergency general surgery with SCC, trauma, and burn rotations, it is an ideal time to determine the optimal curriculum and duration of these important rotations for general surgery residency training.

Resident Preparation for Careers in General Surgery: A Survey of Program Directors

OBJECTIVE

The number of general surgery (GS) residency graduates who choose GS practice has diminished as the popularity of postresidency fellowships has dramatically increased over the past several decades. This study was designed to document current methods of GS preparation during surgery residency and to determine characteristics of programs that produce more graduates who pursue GS practice.

DESIGN

An email survey was sent by the American Board of Surgery General Surgery Advisory Committee to program directors of all GS residencies. Program demographic information was procured from the American Board of Surgery database and linked to survey results. Multiple regression was used to predict postresidency choices of graduates.

SETTING

Totally, 252 US allopathic surgical residencies.

PARTICIPANTS

Totally, 171 residency program directors (68% response rate).

RESULTS

The proportion of programs using an emergency/acute care surgery rotation at the main teaching hospital to teach GS increased from 63% in 2003 to 83% in 2014. An autonomous GS outpatient experience was offered in 38% of programs. Practice management curricula were offered in 28% of programs. Institutions with fewer postresidency fellowships (p < 0.003) and fewer surgical specialty residencies (p < 0.036) had a greater percentage of graduates who pursued GS practice. The addition of each fellowship at an institution was associated with a 2% decrease in the number of graduates pursuing GS practice. Residency size was not associated with predilection for fellowship selection and there was no difference between university and independent residencies vis-a-vis the proportion selecting fellowship vs GS practice.

CONCLUSIONS

Practice management principles and autonomous GS outpatient clinic experiences are offered in a minority of programs. Graduates of programs in institutions with fewer surgery fellowships and residencies are more likely to pursue GS practice. Increased number of postresidency fellowships and specialty residencies may be associated with fewer GS rotations and fewer GS mentors. Further study of these relationships seems warranted.

WSES guidelines for management of Clostridium difficile infection in surgical patients

In the last two decades there have been dramatic changes in the epidemiology of Clostridium difficile infection (CDI), with increases in incidence and severity of disease in many countries worldwide. The incidence of CDI has also increased in surgical patients. Optimization of management of C difficile, has therefore become increasingly urgent. An international multidisciplinary panel of experts prepared evidenced-based World Society of Emergency Surgery (WSES) guidelines for management of CDI in surgical patients.

World Society of Emergency Surgery (WSES) guidelines for management of skin and soft tissue infections

Skin and soft tissue infections (SSTIs) encompass a variety of pathological conditions ranging from simple superficial infections to severe necrotizing soft tissue infections. Necrotizing soft tissue infections (NSTIs) are potentially life-threatening infections of any layer of the soft tissue compartment associated with widespread necrosis and systemic toxicity. Successful management of NSTIs involves prompt recognition, timely surgical debridement or drainage, resuscitation and appropriate antibiotic therapy. A worldwide international panel of experts developed evidence-based guidelines for management of soft tissue infections. The multifaceted nature of these infections has led to a collaboration among surgeons, intensive care and infectious diseases specialists, who have shared these guidelines, implementing clinical practice recommendations.

Using the American Board of Surgery In-Training Examination to predict board certification: a cautionary study

OBJECTIVE

Although designed as a low-stakes formative examination, the American Board of Surgery In-Training Examination (ABSITE) is often used in high-stakes decisions such as promotion, remediation, and retention owing to its perceived ability to predict the outcome of board certification. Because of the discrepancy between intent and use, the ability of ABSITE scores to predict passing the American Board of Surgery certification examinations was analyzed.

METHODS

All first-time American Board of Surgery qualifying examination (QE) examinees between 2006 and 2012 were reviewed. Examinees' postgraduate year (PGY) 1 and PGY5 ABSITE standard scores were linked to QE scores and pass/fail outcomes (n = 6912 and 6846, respectively) as well as first-time certifying examination (CE) pass/fail results (n = 1329). Linear and logistic regression analyses were performed to evaluate the utility of ABSITE scores to predict board certification scores and pass/fail outcomes.

RESULTS

PGY1 ABSITE scores accounted for 22% of the variance in QE scores (p < 0.001). PGY5 scores were a slightly better predictor, accounting for 30% of QE score variance (p < 0.001). Analyses showed that selecting a PGY5 ABSITE score that maximized overall decision accuracy for predicting QE pass/fail outcomes (86% accuracy) resulted in 98% sensitivity, 13% specificity, a positive predictive value of 87%, and a negative predictive value of 57%. ABSITE scores were not predictive of success on the CE.

CONCLUSIONS

ABSITE scores are a useful predictor of QE scores and outcomes but do not predict passing the CE. Although scoring well on the ABSITE is highly predictive of QE success, using low ABSITE scores to predict QE failure results in frequent decision errors. Program directors and other evaluators should use additional sources of information when making high-stakes decisions about resident performance.

Bacterial species-specific hospital mortality rate for intra-abdominal infections

BACKGROUND

Intra-abdominal infections (IAIs) are a major cause of morbidity and death. We hypothesized that the involvement of specific organisms would predict death independently.

PATIENTS AND METHODS

All patients with IAIs treated at an academic tertiary-care facility over eight years (June 1999-June 2007) were included. The data collected were demographics, co-morbidities, source of infection, intra-abdominal culture results, type of infection (community-acquired vs. nosocomial), type of intervention (operative vs. percutaneous drainage), and outcome. The Charlson Comorbidity Index and multiple organ dysfunction score (MODS) were used in the analysis.

RESULTS

A total of 389 patients were admitted for 452 infection episodes (IEs) during the study period. None of the 129 patients with appendiceal-related infections died, and these patients were excluded from further analysis. Thus, 323 non-appendiceal IEs were evaluated. The overall mortality rate was 8.7%. The mean age of the patients was 54 y, and 50% of them were male. Intra-abdominal cultures were obtained from 303 IEs (93.8%). The most common cause of IAI was post-operative infection (44%). There were 49 distinct species isolated. The most common were Enterococcus (105), Escherichia coli (75), Streptococcus (62), Staphylococcus (51), and Bacteroides (46). Bivariable analysis revealed multiple risk factors associated with death. Logistic regression demonstrated that independent risk factors for death were age ≥65 years (odds ratio [OR] 3.92), cardiac event (OR=8.17), catheter-related blood stream infection (OR=6.16), and growth of Clostridium (OR=13.03). The growth of Streptococcus was predictive of survival. The C statistic was 0.89.

CONCLUSIONS

In addition to age and intrinsic patient factors, the presence of specific bacterial organisms independently predicts death in patients with non-appendiceal IAI.

Operative experience of surgery residents: trends and challenges

OBJECTIVE

To evaluate trends in operative experience and to determine the effect of establishing the Surgical Council on Resident Education (SCORE) operative classification system on changes in operative volume among graduating surgery residents.

DESIGN

The general surgery operative logs of graduating surgery residents from 2005 were retrospectively compared with residents who completed training in 2010 and 2011. Nonparametric statistical analyses were used (Mann-Whitney and median test) with significance set at p<0.01.

PARTICIPANTS

A total of 1022 residents completing residency in 2005 were compared with 1923 residents completing training in 2010-2011.

RESULTS

Total operations reported increased from a median of 1023 to 1238 (21%) between 2005 and 2010-2011 (p<0.001). Cases increased in most SCORE categories. The median numbers of total, basic, and complex laparoscopic operations increased by 49%, 37%, and 82%, respectively, over the 5-year interval (p<0.001). Open cavitary (thoracic + abdominal) operations decreased by 5%, whereas other major operations increased by 35% (both p<0.001). The frequency of discrete operations done at least 10 times during residency did not change. The median number of SCORE essential-common operations performed ranged from 1 to 107, whereas essential-uncommon operations ranged from 0 to 4. Twenty-three of 67 SCORE essential-common operations (34%) had a median of less than 5 and 4 had a median of 0.

CONCLUSIONS

The operative volume of graduating surgical residents has increased by 21% since 2005; however, the number of operations done 10 times or greater has not changed. Although open cavitary procedures continue to decline, there has been a large increase in endoscopy, complex laparoscopic, and other major operations. Some essential-common operations continue to be performed infrequently. These results suggest that education in the operating room must improve and alternate methods for teaching infrequently performed procedures are needed.

Does success on the American Board of Surgery general surgery qualifying examination guarantee certifying examination success?

OBJECTIVE

The purpose of this study was to explore the relationship between qualifying examination (QE) and certifying examination (CE) results and to determine whether an appropriate cut-point on the QE would predict success on the CE.

DESIGN

The scaled American Board of Surgery (ABS) QE scores of all first-time examinees from 2006 to 2010 were retrospectively matched to their first-time CE pass/fail decisions. Contingency tables illustrating the QE-CE relationship were constructed and appropriate correlational statistics were computed. A receiver operating characteristic (ROC) curve analysis was constructed, with sensitivity and 1-specificity calculated for each possible QE cut-point used to predicted CE pass/fail classifications. Additionally, the area under the curve (AUC) was calculated.

PARTICIPANTS

All first-time American Board of Surgery examinees for the Surgery Qualifying Examination from 2006 to 2010.

RESULTS

A total of 4385 surgeons were analyzed, with QE scores averaging 82.1 ± 5.8 (range, 58-99) and 82.8% of surgeons passing the CE on their first attempt. Contingency tables suggest a moderate relationship between QE and CE performance, although correlation indexes are low (phi = 0.13, point-biserial = 0.23). For the ROC analysis, the AUC = 0.674 (95% CI; 0.654-0.695) provides a better than chance pass/fail classification (p < 0.001), yet does not meet the minimum threshold for acceptability as a predictive test. No QE cut-point accurately predicted CE pass/fail decisions.

CONCLUSIONS

While a moderate relationship between QE scores and CE performance is evident, correlations suggest that the 2 examinations measure different abilities. The low AUC value on the ROC analysis, along with poor predictability at all possible cut-points, show that no appropriate cut-point on the QE predicts success on the CE. These data add to the validity of both tests by providing evidence that distinct latent traits are being measured by both tests.

Is it time to recast the principles of antimicrobial prophylaxis?

Perioperative antimicrobial prophylaxis has been a time-honored principle in the prevention of surgical site infection. Its effectiveness has recently been questioned. Potential reasons for the lack of demonstrable efficacy and suggestions for re-examination of this concept are presented.

Glycocalyx Enhances Prosthetic Vascular Graft Infection

Coagulase-negative staphylococci are major pathogens in prosthetic implant infections, and the capability of certain strains to produce glycocalyx enhances their infectivity. We investigated the importance of glycocalyx in an animal model of prosthetic vascular graft infection. Coagulasenegative staphylococci (5×108) and 1 cm2pieces of Dacron or polytetrafluoroethylene (PTFE) grafts were placed in subcutaneous pockets of adult Sprague-Dawley rats. Two strains of bacteria were used, one producing and the other not producing glycocalyx. At 5 days, uninfected grafts were incorporated into the surrounding tissues whereas infected grafts were surrounded by fluid. Grafts were excised and adherent bacteria dislodged by sonication and quantitated. Scanning electron microscopy confirmed the presence of bacteria and glycocalyx, and the efficiency of bacterial dislodgement by sonication. The bacterial adherence (CFU/cm2mean ± SE) of glycocalyx-producing staphylococci was 3.7±1.1×107and 3.5±1.0×105to Dacron and PTFE, respectively (both < 0.05). Nonglycocalyx producing bacteria had decreased adherence to both Dacron (1.4±0.8×104) and PTFE (0.9±0.4±104). Antibiotic administration reduced the adherence of the nonglycocalyx producing strain by one log to both materials (p<0.05) but did not affect the glycocalyx-producing strain. These data demonstrate that glycocalyx production enhances the adherence of coagulase-negative staphylococci to prosthetic vascular graft materials. Prophylactic antibiotic administration does little to inhibit the adherence of glycocalyxproducing bacteria but does affect nonglycocalyx producing strains.

Trauma Team Activation can be Tailored by Prehospital Criteria

A two phase prospective study was carried out at a regional Level I trauma center over 1 year. Phase I involved collecting observational data to determine which trauma criteria could potentially be used to identify patients that could be evaluated by a lower level trauma activation (category-3). A category-3 involved a smaller response team with priority access to imaging. Phase II involved implementing this third tier activation system and prospectively evaluating the outcomes related to resources and patient care. A total of 3104 patients were evaluated with 2076 patients in phase I and 1037 in phase II. Three commonly identified activation criteria out of the 36 studied were not associated with admission. These criteria were pedestrian struck by vehicle, high speed vehicular crash, and Glasgow Coma Score 12-14. These criteria were then used as triggers for a category-3 activation in phase II. Comparisons of patients with these three identified criteria between phase I and II demonstrated that significantly fewer patients were admitted, charges were reduced, emergency department times were similar, and less man-power hours were needed in phase II. The utilization of a third tiered activation system resulted in a decrease utilization of many resources without sacrificing patient care.

Moving beyond traditional measurement of mortality after injury: evaluation of risks for late death

BACKGROUND

The purpose of this study was to evaluate long-term mortality after trauma, and to determine risk factors and possible disparities related to mortality after hospital discharge.

STUDY DESIGN

Level I trauma center registry data from a 6-year period (2000 through 2005) were linked to patient electronic medical records, the National Death Index with cause of death codes, and census data using geographic information science (GIS) methodologies. Census data provided supplemental demographic and socioeconomic information from patient neighborhoods.

RESULTS

The hospital mortality rate for 15,285 patients was 3.3%, and mortality after discharge was 4.8%. Overall mortality for the study period was 8.1% (average follow-up, 2.8 years, 1-year mortality, 5.4%). Mortality after discharge was related to the initial injury in 33%, possibly related in 23%, and unrelated in 44% of patients. Logistic regression analysis demonstrated that independent predictors of hospital mortality were age, Injury Severity Score, gunshot injury, significant head injury, fall, and spinal cord injury. In contrast, independent risk factors for mortality after discharge were age, hospital length of stay, discharge from the hospital to a locale other than home, and the presence of spinal cord injury. Intoxication at hospital admission and injury due to a gunshot wound or motor vehicle collision were protective for late mortality. Bivariate analysis of census data demonstrated that lower socioeconomic status was associated with improved hospital survival, and non-native status was associated with mortality after discharge.

CONCLUSIONS

There is significant mortality attributable to trauma for up to 1 year after hospital discharge. These findings suggest that mortality after trauma needs to be measured beyond hospital discharge in order to assess the complete impact of injury.

Follow-up disparities after trauma: a real problem for outcomes research

INTRODUCTION

The objectives of this study were to (1) determine risk factors associated with failure to follow-up (FTF) after traumatic injury and (2) in those patients who do follow up, to determine if information within the electronic medical record (EMR) is an adequate data-collection tool for outcomes research.

METHODS

A 6-year retrospective analysis was conducted on all admitted trauma patients using data from the trauma registry, National Death Index, 2000 Census Data, and the EMR. Bivariate and logistic regression analyses identified risk factors for FTF. A subgroup analysis evaluated the utility of using the EMR to determine basic functional outcomes (Glasgow outcome scale, diet, ambulation, and employment status).

RESULTS

A total of 14,784 patients were discharged, and 61% had follow-up appointments. Lower income, higher poverty rates, and lower education were significantly (P<.05) associated with FTF. Logistic regression analysis (excluding census data) identified that older age, lower Injury Severity Score, less severe head injury, nonwhite race, blunt injury, death after discharge, zip code within 25 miles, and patients discharged to home independently predicted FTF after traumatic injury. A subgroup analysis of the EMR showed the inability to reliably determine functional outcomes.

CONCLUSIONS

There are several disparities related to follow-up after trauma. Furthermore, charting deficiencies, even with an EMR, highlight the weaknesses of data available for trauma outcomes research. Trauma process improvement programs could target patients at risk for not following up and use a structured electronic outpatient note.

Mortality for intra-abdominal infection is associated with intrinsic risk factors rather than the source of infection

BACKGROUND

Intra-abdominal infections (IAIs) are an important cause of mortality and morbidity. Nosocomial IAIs (NIAIs) have been associated with higher mortality than community-acquired IAIs (CIAIs). We hypothesized that intrinsic risk factors were a better predictor of mortality than the type of infection.

METHODS

Patients with IAI treated at a single urban academic hospital over 8 years (June 1999-June 2007) were retrospectively reviewed. Data collected included demographics, comorbidities, source of infection, type of infection (community vs nosocomial), type of intervention (operation versus percutaneous drainage), and postoperative complications. Charlson Comorbidity Index and multiple organ dysfunction (MOD) scores were evaluated at admission and on postoperative day 7 (POD-7).

RESULTS

There were 452 patients; 234 (51.8%) had CIAI and 218 (48.2%) had NIAI. The mean age was 51.3 +/- 0.8. The most common source of CIAI was the appendix (n = 129, 28.5%); 137 patients with NIAI had postoperative infections (30.3%). When patients with appendicitis were excluded, there was no difference in mortality or complications between patients with CIAI and NIAI. Logistic regression analysis demonstrated catheter-related bloodstream infection (P < .001; OR 7.3, 95% CI, 2.5-22.2), cardiac event (P < .001; OR 6.0, 95% CI, 2.3-16.1), and age > or = 65 (P = .009; OR 3.8, 95% CI, 1.4-8.8) to be independent risk factors for mortality. Among patients who failed initial therapy, a non-appendiceal source of infection (P < .001; OR 4.7, 95% CI, 2.3-9.8) and a Charlson score > or =2 (P = .033; OR 1.6, 95% CI, 1.0-2.6) were determined to be independent risk factors. Non-appendiceal source of infection (P = .001, OR 3.3, 95% CI, 1.6-7.0) and POD-7 MOD score > or =4 (P < .001; OR 3.4, 95% CI, 1.9-6.0) were found to be independent predictors for re-intervention.

CONCLUSION

These results suggest mortality from IAI is strongly related to age and organ dysfunction; however, catheter-related bloodstream infection and postoperative cardiac events have a greater effect on outcome.
