Impact clinique et économique d’une politique de contrôle de la sédation par protocole dans un service de réanimation médicochirurgicale

Objective

Since the last consensus conducted by Sfar/SRLF, the use of protocol for sedation became the reference in our ICUs. Decrease in length of stay and length of mechanical ventilation with used of these protocols have been already described. We would like to investigate the economic impact associated.

Study design

Using the PMSI data, we studied retrospectively, the economic effect, one year before and one year after protocol implementation in our ICU.

Method

The economic evaluation compared the cost of sedation but also the cost of mechanical ventilation and length of stay in ICU.

Results

Characteristic and number of patients were equivalent during the two years. We described a significant decrease in length of mechanical ventilation (8.8 vs. 8.4; p < 0.05) but not in length of stay (11.4 vs. 11.7; NS) between the two periods. We described a decrease of sedation cost of 11 412 euros and a decrease of mechanical ventilation cost of 27 360 Euros between the two years.

Conclusion

We confirm in this study that use of sedation protocol in ICU is associated with a clinical impact but also with an economic effect.     

Procalcitonin in the recognition of complications in critically ill surgical patients

Background

Procalcitonin (PCT) is a relatively new, promising indirect parameter for infection. In the intensive care unit (ICU) it can be used as a marker for sepsis. However, in the ICU there is a need for reliable markers for clinical deterioration in the critically ill patients. This study determines the clinical value of PCT concentrations in recognizing surgical complications in a heterogeneous group of general surgical patients in the ICU.

Material and methods

We prospectively collected PCT concentration data from April 2010 to June 2012 for all general surgical patients admitted to the ICU. Both the relationships between PCT levels and events (diagnostic and therapeutic interventions) as well as between PCT levels and surgical complications (abscesses, bleeding, perforation, ischemia, and ileus) were studied.

Results

PCT concentrations were lower in patients who developed complications than those who did not develop complications on the same day, although not significant (P = 0.27). A 10% increase in PCT levels resulted in a 2% higher complication odds, but again this was not significant (odds ratio [OR], 1.020; 95% confidence interval [CI], 0.961–1.083; P = 0.51). Even a 20% or 30% increase in PCT concentrations did not result in higher complication probability (OR, 1.039; 95% CI, 0.927–1.165 and OR, 1.057; 95% CI, 0.897–1.246). Furthermore, an increase in PCT levels did not show an increase or a reduction in the number of diagnostic and therapeutic interventions.

Conclusions

An increase in PCT levels does not help to predict surgical complications in critically ill surgical patients.     

La sédation–analgésie au quotidien : enquête de pratiques auprès de 218 services de réanimation en France

Objectives

To assess the current use of sedation and analgesia in a large sample of French intensive care units (ICUs) and to define structural characteristics of the units that use a written procedure.

Study design

Self-reported survey.

Participants

Three hundred and sixty French ICUs were presented the questionnaire in September 2007.

Results

Surveys were received from 228 (60.6%) ICUs. Midazolam was used in more than 50% of the patients in 79.2% of the ICUs and propofol in 22.2% of the ICUs. Sufentanil was the most frequently used morphinic. A sedation-scale was used in 68.8% of the units (80.3% Ramsay score). Sedation was assessed at least every 4 hours in 61% of ICUs. A pain-scale was used in 88.9% of the ICUs, but only 12.5% in the non-communicant patients. A written procedure was used in 29.4% of the units only. In multivariate analysis, use in the ICU of a written procedure for the early management of patients with septic shock and/or intensive insulin therapy was the single variable significantly associated with presence of a written procedure for sedation and analgesia (respectively OR 4.37; p < 0.0001 and OR 5.64; p = 0.032).

Conclusion

Although more than two-third of the responding ICUs reported the use of sedation-and-pain-scales, frequency of assessment was low, and objective assessment of pain in the non-communicating patients was extremely uncommon. Similarly, the use of written procedure was low. The use of sedation-analgesia written procedure in an ICU seems strongly influenced by a more global involvement of the ICU in the protocolisation of complex care. These findings support the reinforcement of educational programs.     

Intensive care unit design and mortality in trauma patients

Background

The architecture of medical care facilities ca affect the safety of a patient, but it is unknown if the architecture affects outcomes. We hypothesized that patients in rooms who are more visible from the central nursing station would experience better outcomes than those patients in less visible rooms.

Materials and methods

A total of 773 patients admitted to the trauma intensive care service over a 12-mo period were retrospectively evaluated. Outcomes were hospital mortality and intensive care unit (ICU) length of stay (LOS). The unit is designed with a bank of high-visibility rooms (HVRs) directly across from the nursing station and two side sections of low-visibility rooms (LVRs). No formal triage occurs, but patients are prioritized to HVRs as available.

Results

Patients in the HVRs had a 16% mortality (52 of 320); meanwhile, the patients in the LVRs experienced an 11% mortality (49 of 448, P = 0.03). ICU mortality did not differ significantly when controlling for age, Charlson Comorbidity Index (CCI), Head Abbreviated Injury Score, and the Injury Severity Score (ISS) (P = 0.076). Age, CCI, Head Abbreviated Injury Score, and ISS did individually correlate with mortality (age: P = 0.0008; CCI: P = 0.017; and ISS: P < 0.0001). Visibility was not a predictor of ICU LOS or complications among survivors (mean ICU HVR LOS = 4.8 d; mean ICU LVR LOS = 4.7; P = 0.88, n = 661). Only ISS was a significant predictor of ICU LOS and complications (P < 0.0001).

Conclusions

Trauma patient room placement within the ICU does not relate to mortality rate significantly when corrected for patient acuity. Instead, variables such as age, ISS, and CCI are associated with mortality. A policy of placing more critically ill patients in HVRs may prevent increased mortality in high-acuity patients.     

Clinical benefits of dexmedetomidine versus propofol in adult intensive care unit patients: a meta-analysis of randomized clinical trials

Background

This meta-analysis was performed to assess the influence of dexmedetomidine and propofol for adult intensive care unit (ICU) sedation, with respect to patient outcomes and adverse events.

Materials and methods

A systematic review was conducted of all randomized controlled trials exploring the clinical benefits of dexmedetomidine versus propofol for sedation in adult intensive care patients. The primary outcomes of this study were length of ICU stay, duration of mechanical ventilation, and risk of ICU mortality. Secondary outcomes included risk of delirium, hypotension, bradycardia and hypertension.

Results

Ten randomized controlled trials, involving 1202 patients, were included. Dexmedetomidine significantly reduced the length of ICU stay by <1 d (five studies, 655 patients; mean difference, −0.81 d; 95% confidence interval [CI], −1.48 to −0.15) and the incidence of delirium (three studies, 658 patients; relative risk [RR], 0.40; 95% CI, 0.22–0.74) in comparison with propofol, whereas there was no difference in the duration of mechanical ventilation (five studies, 895 patients; mean difference, 0.53 h; 95% CI −2.66 to 3.72) or ICU mortality (five studies, 267 patients; RR, 0.83; 95% CI, 0.32–2.12) between these two drugs. Dexmedetomidine was associated with an increased risk of hypertension (three studies, 846 patients; RR, 1.56; 95% CI, 1.11–2.20) compared with propofol. Other adverse event rates were similar between dexmedetomidine and propofol groups.

Conclusions

For ICU patient sedation, dexmedetomidine may offer advantages over propofol in terms of decrease in the length of ICU stay and the risk of delirium. However, transient hypertension may occur when dexmedetomidine is administered with a loading dose or at high infusion rates.     

Religiously affiliated intensive care unit patients receive more aggressive end-of-life care

Background

Previous studies among cancer patients have demonstrated that religious patients receive more aggressive end-of-life (EOL) care. We sought to examine the effect of religious affiliation on EOL care in the intensive care unit (ICU) setting.

Materials and methods

We conducted a retrospective review of all patients admitted to any adult ICU at a tertiary academic center in 2010 requiring at least 2 d of mechanical ventilation. EOL patients were those who died within 30 d of admission. Hospital charges, ventilator days, hospital days, and days until death were used as proxies for intensity of care among the EOL patients. Multivariate analysis using multiple linear regression, zero-truncated negative binomial regression, and Cox proportional hazard model were used.

Results

A total of 2013 patients met inclusion criteria; of which, 1355 (67%) affirmed a religious affiliation. The EOL group had 334 patients, with 235 (70%) affirming a religious affiliation. The affiliated and nonaffiliated patients had similar levels of acuity. Controlling for demographic and medical confounders, religiously affiliated patients in the EOL group incurred 23% (P = 0.030) more hospital charges, 25% (P = 0.035) more ventilator days, 23% (P = 0.045) more hospital days, and 30% (P = 0.036) longer time until death than their nonaffiliated counterparts. Among all included patients, survival did not differ significantly among affiliated and nonaffiliated patients (log-rank test P = 0.317), neither was religious affiliation associated with a difference in survival on multivariate analysis (hazard ratio of death for religious versus nonreligious patients 0.95, P = 0.542).

Conclusions

Compared with nonaffiliated patients, religiously affiliated patients receive more aggressive EOL care in the ICU. However, this high-intensity care does not translate into any significant difference in survival.     

Delirium prevention program in the surgical intensive care unit improved the outcomes of older adults

Background

Hospital-acquired delirium is a known risk factor for negative outcomes in patients admitted to the surgical intensive care unit (SICU). Outcomes worsen as the duration of delirium increases. The purpose of this study was to evaluate the efficacy of a delirium prevention program and determine whether it decreased the incidence and duration of hospital-acquired delirium in older adults (age >50 y) admitted to the SICU.

Methods

A prospective pre- or post-intervention cohort study was done at an academic level I trauma center. Older adults admitted to the SICU were enrolled in a delirium prevention program. Those with traumatic brain injury, dementia, or 0 d of obtainable delirium status were excluded from analysis. The intervention consisted of multidisciplinary education, a pharmacologic protocol to limit medications associated with delirium, and a nonpharmacologic sleep enhancement protocol. Primary outcomes were incidence of delirium and delirium-free days/30. Secondary outcomes were ventilator-free days/30, SICU length of stay (LOS), daily and cumulative doses of opioids (milligram, morphine equivalents) and benzodiazepines (milligram, lorazepam equivalents), and time spent in severe pain (greater than or equal to 6 on a scale of 1 - 10). Delirium was measured using the Confusion Assessment Method for the ICU. Data were analyzed using Chi-squared and Wilcoxon rank sum analysis.

Results

Of 624 patients admitted to the SICU, 123 met inclusion criteria: 57 preintervention (3/12–6/12) and 66 postintervention (7/12–3/13). Cohorts were similar in age, gender, ratio of trauma patients, and Injury Severity Score. Postintervention, older adults experienced delirium at the same incidence (pre 47% versus 58%, P = 0.26), but for a significantly decreased duration as indicated by an increase in delirium-free days/30 (pre 24 versus 27, P = 0.002). After intervention, older adults with delirium had more vent-free days (pre 21 versus 25, P = 0.03), shorter SICU LOS (pre 13 [median 12] versus 7 [median 6], P = 0.01) and were less likely to be treated with benzodiazepines (pre 85% versus 63%, P = 0.05) with a lower daily dose when prescribed (pre 5.7 versus 3.6 mg, P = 0.04). After intervention, all older adults spent less time in pain (pre 4.7 versus 3.1 h, P = 0.02), received less total opioids (pre 401 versus 260 mg, P = 0.01), and had shorter SICU LOS (pre 9 [median 5] versus 6 [median 4], P = 0.04).

Conclusions

Although delirium prevention continues to be a challenge, this study successfully decreased the duration of delirium for older adults admitted to the SICU. Our simple, cost-effective program led to improved pain and sedation outcomes. Older adults with delirium spent less time on the ventilator and all patients spent less time in the SICU.     

Effects of an Education Program on Intensive Care Unit Nurses' Attitudes and Behavioral Intentions to Advocate Deceased Donor Organ Donation

Introduction

Organ shortage limits the application of organ transplantation. The attitudes of intensive care unit (ICU) staff play an important role in organ advocating. The effects of an education program for ICU nurses on organ advocating were uncertain. The purpose of this study was to explore the effects of an education program based on the Theory of Planned Behavior (TPB) on ICU nurses' attitudes and behavioral intentions to advocate deceased organ donation.

Methods

Participants were recruited from 3 different ICU units in medical centers and were randomly assigned to either an experimental group (n = 61) or a control group (n = 62). The nurses in the experimental group received comprehensive education programs, and the control groups received a brochure only. The outcome parameters were measured by questionnaires at 3 different time points of pretest, posttests immediately after education, and 2 months later.

Results

Before education, there was no difference in attitude and behavior intentions between the control and experimental groups. After TPB training, the nurses significantly changed their attitudes and behavior intentions on organ advocating, both immediately (P < .01) and 2 months after the education program (P < .01). In addition, multivariate analysis indicated that TPB training is significantly associated with the change of attitude (P < .01) and behavior intention (P < .05) of organ donation advocacy.

Conclusions

TPB education programs enhanced the ICU nurses' attitudes and behavioral intentions on advocating organ donation. Repeated education is advised to increase the participation of ICU nurses on organ advocacy.     

Timing of tracheostomy and outcome of patients requiring mechanical ventilation

Objectives

To assess the impact of tracheostomy timing on outcome of critically ill patients requiring mechanical ventilation (MV).

Study design

Retrospective clinical study in a twelve beds intensive care unit (ICU).

Patients and methods

From January 2001 to June 2005, patients under MV who received tracheostomy were divided into 2 groups: early tracheostomy group when tracheostomy was performed before or on day 7 and late tracheostomy group when it was performed thereafter. We compared prevalence of nosocomial pneumonia, length of sedation, lengths of MV, length of stay in ICU, weaning from MV and mortality rates between the 2 groups.

Results

During this period of 4 years and half, 112 patients underwent tracheostomy, 62 of whom had early tracheostomy and 50 had late tracheostomy. Early tracheostomy was associated with significant reduction of length of sedation (10 ± 3 vs 17 ± 5 days, P < 0.001), length of MV (21 ± 19 vs 29 ± 17 days, P = 0.02) and length of stay in ICU (33 ± 22 vs 42 ± 18 days, P = 0.042). There were no differences in prevalence of pneumonia (21% for early tracheostomy group vs 31% for late tracheostomy group, P = 0, 13), weaning from MV (50 vs 36%, P = 0.19), and mortality rates between the 2 groups (38 vs 54%, P = 0.15).

Conclusion

This study demonstrated that early tracheostomy (≤ 7 days), was associated with shorter length of sedation, shorter duration of MV and shorter ICU length of stay, without affecting weaning from MV, prevalence of nosocomial pneumonia or survival.     

Delayed admission to intensive care unit for critically surgical patients is associated with increased mortality

Background

Shortage of beds in intensive care units (ICUs) is an increasing common phenomenon worldwide. Consequently, many critically ill patients have to be cared for in other hospital areas without specialized staff, such as general wards, emergency department, post anesthesia care unit (PACU). However, boarding critically ill patients in general wards or emergency department has been associated with higher mortality. The purpose of this study was to evaluate if a delay in ICU admission, waiting in PACU and managed by anesthesiologists, affects their ICU outcomes for critically surgical patients.

Methods

A retrospective cohort of adult critically surgical patients admitted to our ICU between January 2010 and June 2012 were analyzed. ICU admission was classified as either immediate or delayed (waiting in PACU). A general estimation equation was used to examine the relationship of PACU waiting hours before ICU admission with ICU outcomes by adjusting for age, patient sex, comorbidities, surgical categories, end time of operation, operation hours, and clinical conditions.

Results

A total of 2,279 critically surgical patients were evaluated. Two thousand ninety-four (91.9%) patients were immediately admitted and 185 (8.1%) patients had delayed ICU admission. There was a significant increase in ICU mortality rates with a delay in ICU admission (P < .001). Prolonged waiting hours in PACU (≥6 hours) was associated with higher ICU mortality (adjusted odds ratio 5.32; 95% confidence interval 1.25 to 22.60, P = .024). However, longer PACU waiting times was not associated with mechanical ventilation days, ICU length of stay, and ICU cost.

Conclusion

Prolonged waiting hours in PACU because of ICU bed shortage was associated with higher ICU mortality for critically surgical patients.     

Prospective validation of a surgical complications grading system in a cohort of 2114 patients

Background

We recently reported a grading system for surgical complications. This system proved to have a high sensitivity for recording minor but meaningful complications prolonging hospital stay in patients after colorectal surgery. We aimed to prospectively validate the complication grading system in a general surgery department over 1 year.

Methods

All surgical procedures and related complications were prospectively recorded between January 1st and December 31st, 2009. Surgical complications were graded on a severity scale of 1-5. The system classifies short-term outcome by grade emphasizing intensity of therapy required for treatment of the defined complication.

Results

During the study period, 2114 patients underwent surgery. Elective and oncological surgeries were performed in 1606 (76%) and 465 (22%) patients, respectively. There were 422 surgical complications in 304 (14%) patients (Grade 1/2: 203 [67%]; Grade 3/4: 90 [29%]; Grade 5: 11 [4%]).Median length of stay correlated significantly with complication severity: 2.3 d for no complication, 6.2 and 11.8 d for Grades 1/2 and 3/4, respectively (P < 0.001). Older age (OR 2.75, P < 0.001), comorbidities (OR 1.44, P = 0.02), American Society of Anesthesiology score >2 (OR 2.07, P < 0.001), contamination Grade (OR 1.85, P = 0.001), oncological (OR 2.82, P < 0.001), open (OR 1.22, P = 0.03), prolonged >120 min (OR 2.08, P < 0.001), and emergency surgery (OR 1.42, P = 0.02) independently predicted postoperative complications.

Conclusions

This system of grading surgical complications permits standardized reporting of surgical morbidity according to the severity of impact. Prospective validation of this system supports its use in a general surgery setting as a tool for surgical outcome assessment and quality assurance.     

The effect of supplemental parenteral nutrition on outcomes of necrotizing enterocolitis in premature,low birth weight neonates

Background

We hypothesized that supplemental parenteral nutrition (PN) decreases the need for surgery and mortality associated with necrotizing enterocolitis (NEC).

Methods

Single institution retrospective review of all premature, low birth weight infants with NEC from January 2006 to December 2013 was conducted.

Results

NEC was identified in 114 premature, low birth weight infants, 59 (51.8%) of which required surgical management. Surgical NEC infants were born younger (25.8 ± 4.0 vs 27.8 ± 3.3 weeks, P = .005) and weighed less at birth (829 ± 281 vs 938 ± 271 g, P = .038) than those managed medically. There was no difference in the use of PN (37.7% vs 31.4%, P = .541) between surgical and medical NEC patients. There was no statistically significant difference in mortality at discharge between patients who had PN at NEC onset and those who did not (31.4% vs 42.6%, P = .294)

Conclusion

In this single-center study, supplemental PN at NEC onset does not appear to significantly improve outcomes as demonstrated by rates of surgical intervention and in-hospital mortality.     

Atrial Fibrillation in Patients Undergoing Liver Transplantation—A Single-Center Experience

Background

As the prevalence of atrial fibrillation rises with age and older patients increasingly receive transplants, the perioperative management of this common arrhythmia and its impact on outcomes in liver transplantation is of relevance.

Methods

Retrospective review of 757 recipients of liver transplantation from January 2002 through December 2011.

Results

Nineteen recipients (2.5%) had documented pre-transplantation atrial fibrillation. Sixteen patients underwent liver and 3 a combined liver-kidney transplantation. Three patients died within 30 days (84.2% 1-month survival) and another 3 within 1 year of transplantation (68.4% 1-year survival). Compared with patients without atrial fibrillation, the relative risk of death in the atrial fibrillation group was 5.29 at 1 month (P = .0034; 95% confidence interval [CI], 1.73–16.18) and 3.28 at 1 year (P = .0008; 95% CI, 1.63–6.59). Time to extubation and intensive care unit (ICU) and hospital readmissions were not different from the control cohort. Rapid ventricular response requiring treatment occurred in 4 patients during surgery and 7 after surgery, resulting in 3 ICU and 3 hospital readmissions.

Conclusions

The results suggest that patients with atrial fibrillation may be at increased risk of mortality after liver transplantation. Optimization of medical therapy may decrease ICU and hospital readmission due to rapid ventricular response.     

Mortality rates increase dramatically below a systolic blood pressure of 105-mm Hg in septic surgical patients

Background

This study used a prospective surgical database, to investigate the level of systolic blood pressure (SBP) at which the mortality rates begin to increase in septic surgical patients.

Methods

All acute, septic general surgical patients older than 15 years of age admitted between January 2012 and January 2015 were included in these analyses.

Results

Of a total of 6,020 adult surgical patients on the database, 3,053 elective patients, 1,664 nonseptic, 52 duplicates, and 11 patients with missing SBP were excluded to leave a cohort of 1,232 acute, septic surgical patients. The median age (intraquartile range [IQR]): 48 (32 to 62) and roughly 50:50 sex ratio (620 female: 609 male). Most of the patients were African: 988 (80.2%) followed by Asians (128 or 10.4%). More than two-thirds (852 or 69.2%) of the patient cohort underwent some form of surgery, and 152 or 12.3% required intensive care unit (ICU) admission. The median length of ICU stay (IQR) was 2 (1 to 4.5) days. The median length of total hospital stay (IQR) was 4 (2 to 9) days. The median SBP (IQR) on admission was 122 (107 to 138). A total of 167 patients died (13.6%). Those that died did have a significantly lower mean SBP compared with the survivors (116 vs 125, P <. 001). Six of 10 patients (60%) with a SBP less than 70 died. The receiver operating characteristic analysis suggests an optimal SBP cut-off of 111 when predicting mortality (area under the receiver operating characteristic curve: .6 [.551, .65]). This cut-off yields a moderate sensitivity (70%), high positive predictive value (90%) but low specificity, and negative predictive value when predicting mortality. Based on this optimal cut-off, 388 or 31.5% of the patients would be classified as shocked. The inflection curve below with fitted nonlinear curve (95% confidence intervals) clearly shows the upward change in observed mortality frequency at lower systolic and base excess (ie base deficit) values. Shocked patients had a significantly higher frequency of mortality (20% vs 11%, P < .001), a significantly higher median lactate (1.9 vs 1.5, P < .001), and mean base deficit (−2.8 vs −1.0, P = .001). No significant difference in mean age, ICU admission, duration of ICU admission, and total length of hospital stay was observed by shocked status.

Conclusions

Our data suggest that patients who die have a significantly lower SBP and clinically significant hypotension in sepsis with regard to increased mortality risk begins at a level of ∼111-mm Hg. This finding needs to be incorporated into bundles of care for surgical sepsis.     

The impact of adhesions on operations and postoperative recovery in colon cancer surgery

Background

Many surgeons assume that adhesions encountered during surgery negatively influence surgical outcomes. This article attempts to assess the role adhesions have on outcomes of colon cancer surgery.

Methods

Records of 1,071 consecutive patients operated for colonic adenocarcinoma (2004–2011) were reviewed. Patients were assigned to 3 groups: no adhesions, any adhesions, or dense adhesions. Multivariate regression assessed the association between adhesions and the duration of surgery and stay as well as laparoscopic conversion and complication rates.

Results

Adhesions were encountered in 329 (30.7%) patients; 138 (12.8%) had dense adhesions. After correction for age and comorbidities, having adhesions was associated with longer surgeries (P < .001), longer hospital stays (P = .029), a borderline significantly higher conversion rate (P = .058), and a delayed return of bowel function (P = .037). Dense adhesions had stronger associations with surgical duration (P < .001), stay duration (P < .001), and conversion (P < .001).

Conclusions

Abdominal adhesions independently put patients at risk for a longer and more complicated perioperative stay after colon cancer surgery.     

Facteurs prédictifs de défaillance d’organes chez les patients admis en réanimation pour hémorragie digestive aiguë

Introduction

Gastrointestinal hemorrhage is an emergency requiring usually an admission in intensive care unit (ICU), which may prove abusive secondarily. The aim of this study was to identify predictive risk factors of organ failure in patients admitted for GH in our ICU.

Design

Retrospective and observational

Methods and measurements

Between January 2008 and December 2011, all patients admitted in our ICU for gastrointestinal hemorrhage were consecutively included. The primary endpoint was the occurrence of at least an organ failure. We realized an univariate analysis then a backward regression to identify independent risk factors associated with the occurrence of at least one organ failure during the ICU hospitalization.

Results

During this period study, 441 consecutive patients with a mean age of 67 ± 15 years were included. The median ICU length of stay was of 4 (3–7) days and 116 (26% [IC95%: 22–30]) patients presented at least one organ failure. The multivariate analysis identified predictive risk factors of organ failure: history of cirrhosis (OR = 3.5 [IC95%: 1.9–6.7], P < 0.001) and an increase in troponin at the admission above the 99th percentile (OR = 3.1 [IC95%: 1.8–5.5], P < 0.001).

Conclusion

Our results confirmed that a large proportion of patients admitted in ICU for the primary diagnosis of gastrointestinal hemorrhage developed any organ failure. The history of cirrhosis and the systemic consequences of the hemorrhagic syndrome as myocardial damage represents important risk factors of morbidity and mortality and thus should be considered during the management.     

Comparison Between Resection and Transplantation in Combined Hepatocellular and Cholangiocarcinoma

Objective

The treatment of choice for combined hepatocellular and cholangiocarcinoma (cHCC-CC) is surgical resection. However, the efficacy of liver transplantation is not clear. We compared the surgical outcome of hepatic resection and liver transplantation for cHCC-CC.

Patients and methods

From 1995 to 2012, 89 patients were diagnosed with cHCC-CC after hepatic resection and 8 patients diagnosed with cHCC-CC after liver transplantation. We excluded 21 patients who were American Joint Committee on Cancer Staging Stage III or IV and lost to follow-up. The outcomes were reviewed retrospectively.

Results

The poor prognostic factors in cHCC-CC patients who underwent hepatectomy were large tumor size (>5 cm), small safety margin (<2 cm), and low preoperative albumin level. The disease-free survival (DFS) and overall survival (OS) between the hepatectomy group (n = 68) and the liver transplant group (n = 8) was not statistically different (5-year DFS: 26.2% vs 37.5%, P = .333; 5-year OS: 42.1% vs 50%, P = .591). In the small tumor subgroup (tumor size <5 cm), the DFS and OS between the 2 surgical procedures was not different, and in the adequate resection margin subgroup (safety margin >2 cm), survival was comparable.

Conclusions

In well-selected cases with small tumor size and with preserved liver function, liver resection should be considered when complete resection is possible.     

Cholecystectomy and Wound Complications: Smoking Worsens Risk

Background

In the United States, approximately 800,000 cholecystectomies are performed annually. We sought to determine the influence of preoperative smoking on postcholecystectomy wound complication rates.

Materials and methods

Using the National Surgical Quality Improvement Program database (2005–2011), patients aged ≥18 y who underwent elective open or laparoscopic cholecystectomy (LC) for benign gallbladder disease were identified using current procedural terminology codes. Multivariate regression was performed to determine the association between smoking status and wound complications, by surgical approach.

Results

Of 143,753 identified patients, 128,692 (89.5%) underwent LC, 27,788 (19.3%) were active smokers, and 100,710 (70.2%) were females. Active smokers were younger than nonsmokers (mean + standard deviation age: 44.2 (14.9) versus 51.6 (17.9) years); P < 0.001) and had fewer comorbidities. Within 30-d postcholecystectomy, wound complications were reported in 2011 (1.4%) patients. Compared with nonsmokers, active smokers demonstrated increased odds of wound complications after both open cholecystectomy (odds ratio 1.28; P = 0.010) and LC (odds ratio 1.20; P = 0.020) after adjustment for demographic and clinical characteristics. Having wound complications increased the average postoperative length of stay by 2–4 d (P <0.001).

Conclusions

Active smokers are more likely to develop wound complications after cholecystectomy, regardless of surgical approach. Occurrence of wound complications consequently increases postoperative length of stay. Smoking abstinence before cholecystectomy may reduce the burden associated with wound complications.     

Surgical specialty and outcomes for carotid endarterectomy: evidence from the National Surgical Quality Improvement Program

Background

Carotid endarterectomy (CEA) has been performed since the 1950s and remains one of the most common surgical procedures in the United States. The procedure is performed by cardiothoracic, general, neurologic, and vascular surgeons. This study uses data from the National Surgical Quality Improvement Program (NSQIP) to examine the outcomes after CEA when performed by general or vascular surgeons.

Materials and methods

Data included 34,493 CEAs from years 2005 to 2010 recorded in the NSQIP database. Primary outcomes measured were length of stay, 30-d mortality, surgical site infection, cerebrovascular accident, myocardial infarction, and blood transfusion requirement. Secondary outcomes measured were the remaining intraoperative outcomes from the NSQIP database.

Results

After controlling for patient and surgical characteristics, patients treated by general surgeons did not have a significantly different LOS or 30-d mortality than those treated by vascular surgeons. Patients of general surgeons had nearly twice the risk of acquiring a surgical site infection (odds ratio [OR] = 1.94; P = 0.012), >1.5 times the risk of cerebrovascular accident (OR = 1.56; P = 0.008), and >1.8 times the risk of blood transfusion (OR = 1.85; P = 0.017) than those of vascular surgeons. Patients of general surgeons had less than half the risk of having a myocardial infarction (OR = 0.34; P = 0.031) than those of vascular surgeons.

Conclusions

Surgical specialty is associated with a wide range of postoperative outcomes after CEA. Additional research is needed to explore practice and cultural differences across surgical specialty that may lead to outcome differences.
