Enhanced recovery after pancreatic surgery: a systematic review of the evidence

Background

Enhanced recovery after surgery (ERAS) protocols have been shown to reduce hospital stay without compromising outcomes. Attempts to apply ERAS principles in the context of pancreatic surgery have generated encouraging results. A systematic review of the current evidence for ERAS following pancreatic surgery was conducted.

Methods

A literature search of MEDLINE, CINAHL, EMBASE and the Cochrane Library was performed for articles describing postoperative clinical pathways in pancreatic surgery during the years 2000–2013. The keywords ‘clinical pathway’, ‘critical pathway’, ‘fast-track’, ‘pancreas’ and ‘surgery’ and their synonyms were used as search terms. Articles were selected for inclusion based on predefined criteria and ranked for quality. Details of the ERAS protocols and relevant outcomes were extracted and analysed.

Results

Ten articles describing an ERAS protocol in pancreatic surgery were identified. The level of evidence was graded as low to moderate. No articles reported an adverse effect of an ERAS protocol for pancreatic surgery on perioperative morbidity or mortality. Length of stay (LoS) was decreased and readmission rates were found to be unchanged in six of seven studies that compared these outcomes.

Conclusions

Evidence indicates that ERAS protocols may be implemented in pancreatic surgery without compromising patient safety or increasing LoS. Enhanced recovery after surgery programmes in the context of pancreatic surgery should be standardized based upon the best available evidence, and trials of ERAS programmes involving multiple centres should be performed.     

A systematic review of outcomes in patients undergoing liver surgery in an enhanced recovery after surgery pathways

Objectives

Enhanced recovery after surgery (ERAS) or fast-track protocols have been implemented in different fields of surgery to attenuate the surgical stress response and accelerate recovery. The objective of this study was to systematically review the literature on outcomes of ERAS protocols applied in liver surgery.

Methods

The MEDLINE, EMBASE, PubMed and Cochrane Library databases were searched for randomized controlled trials (RCTs), case–control studies and case series published between January 1966 and October 2011 comparing adult patients undergoing elective liver surgery in an ERAS programme with those treated in a conventional manner. The primary outcome measure was hospital length of stay (LoS). Secondary outcome measures were time to functional recovery, and complication, readmission and mortality rates.

Results

A total of 307 articles were found, six of which were included in the review. These comprised two RCTs, three case–control studies and one retrospective case series. Median LoS ranged from 4 days in an ERAS group to 11 days in a control group. Morbidity, mortality and readmission rates did not differ significantly between the groups. Only two studies assessed time to functional recovery. Functional recovery in these studies was reached 2 days before discharge.

Conclusions

This systematic review suggests that ERAS protocols can be successfully implemented in liver surgery. Length of stay is reduced without compromising morbidity, mortality or readmission rates.     

The effect of a multimodal fast-track programme on outcomes in laparoscopic liver surgery: a multicentre pilot study

Objectives:

This study was conducted to evaluate the added value of an enhanced recovery after surgery (ERAS) programme in laparoscopic liver resections for solid tumours.

Methods:

Patients undergoing laparoscopic liver resection between July 2005 and July 2008 were included. Indications for resections included presumed benign and malignant liver lesions. Primary outcome was total length of hospital stay (LOS). Secondary outcomes were functional recovery, complications, conversions, blood loss and duration of operation.

Results:

Thirteen patients were treated by laparoscopic liver resections in the ERAS programme in one centre (group 1). Their outcomes were compared with outcomes of 13 laparoscopic procedures performed either before the introduction of the ERAS programme during 2003–2005 in the same centre or during the same period in other centres using traditional care (group 2). Median total LOS was 5.0 days (range 3–10 days) in group 1 and 7.0 days (3–12 days) in group 2. This difference was not statistically significant. Functional recovery occurred 2 days earlier in group 1 (median 3.0 days [range 1–7 days] vs. median 5.0 days [range 2–8 days]; P < 0.044). There were no significant differences in complications, conversions or duration of operation. Blood loss was significantly less in the ERAS group (median 50 ml [range 50–200 ml] vs. median 250 ml [range 50–800 ml]; P < 0.002).

Conclusions:

This exploratory, multicentre, fast-track laparoscopic liver resection study is the first such study conducted. Although small, the study suggests that a multimodal enhanced recovery programme in laparoscopic liver surgery is feasible, safe and may lead to accelerated functional recovery and reductions in LOS.     

Does travel distance influence length of stay in elective pancreatic surgery?

Background

Length of stay (LoS) following elective surgery is being reported as an outcomes quality measure. Regional referral centres may care for patients travelling significant distances. The effect of travel distance on LoS in pancreatic surgery patients was examined.

Methods

National Surgical Quality Improvement Program data on pancreatic surgery patients, operated during the period from 2005 to 2011, were reviewed. Demographics, surgical variables and distance travelled were analysed relative to LoS. The LoS was log-transformed in general linear models to achieve normality.

Results

Of the 243 patients, 53% were male. The mean ± standard deviation (SD) age of the total patient sample was 60.6 ± 14 years. The mean ± SD distance travelled was 203 ± 319 miles (326.7 ± 513.4 km) [median: 132 miles (212.4 km); range: 3–3006 miles (4.8–4837.7 km)], and the mean ± SD LoS was 10.5 ± 7 days (range: 1–46 days). Univariate analysis showed a near significant increase in LoS with increased distance travelled (P = 0.05). Significant variables related to LoS were: age (P = 0.002); relative value units (P < 0.001), and preoperative American Society of Anesthesiologists class (P = 0.005). In a general linear model, for every 100 miles (160.9 km) travelled there is an associated 2% increase in LoS (P = 0.031). When the distance travelled is increased by 500 miles (804.7 km), LoS increases by 10.5%.

Conclusions

Increased travel distance from a patient''s home to the hospital was independently associated with an increase in LoS. If LoS is a reportable quality measure in pancreatic surgery, travel distance should be considered in risk adjustments.     

Effects of introducing an enhanced recovery after surgery programme for patients undergoing open hepatic resection

Objectives

Enhanced recovery after surgery (ERAS) protocols are coming to represent the standard of care in many surgical procedures, yet data on their use following hepatic surgery are scarce. The aim of this study was to review outcomes after the introduction of an ERAS programme for patients undergoing open hepatic resection.

Methods

A retrospective review of patients undergoing open hepatic resection from March 2005 to June 2011 was carried out. The primary outcome measure was total hospital length of stay (LoS) (including readmissions). Principles associated with enhanced recovery after surgery were documented and analysed as independent predictors of hospital LoS.

Results

A total of 120 patients underwent 128 consecutive hepatic resections, 84 (65.6%) of which were performed in patients with underlying colorectal metastases and 64 (50.0%) of which comprised major hepatic resections. The median hospital LoS was reduced from 6 days to 3 days from the first to the fourth quartiles of the study population (P = 0.021). The proportion of patients suffering complications (26.6%) remained constant across the series. Readmissions increased from the first quartile (none of 32 patients) to the fourth quartile (seven of 32 patients) (P = 0.044). Following multivariate analysis, only the development of a complication (P < 0.001), total postoperative i.v. fluid (P = 0.003) and formation of an anastomosis (P = 0.006) were independent predictors of hospital LoS.

Conclusions

An ERAS programme can be successfully applied to patients undergoing open hepatic resection with a reduction in hospital LoS, but an increase in the rate of readmissions.     

A survey in the hepatopancreatobiliary community on ways to enhance patient recovery

Objectives

Both laparoscopic techniques and multimodal enhanced recovery programmes have been shown to improve recovery and reduce length of hospital stay. Interestingly, evidence-based care programmes are not widely implemented, whereas new, minimally invasive surgical procedures are often adopted with very little evidence to support their effectiveness. The present survey aimed to shed light on experiences of the adoption of both methods of optimizing recovery.

Methods

An international, web-based, 18-question, electronic survey was composed in 2010. The survey was sent out to 673 hepatopancreatobiliary (HPB) centres worldwide in June 2010 to investigate international experiences with laparoscopic liver surgery, fast-track recovery programmes and surgery-related equipoise in open and laparoscopic techniques and to assess opinions on strategies for adopting laparoscopic liver surgery in HPB surgical practice.

Results

A total of 507 centres responded (response rate: 75.3%), 161 of which finished the survey completely. All units reported performing open liver resections, 24.2% performed open living donor resections, 39.1% carried out orthotopic liver transplantations, 87.6% had experience with laparoscopic resections and 2.5% performed laparoscopic living donor resections. A median of 50 (range: 2–560) open and 9.5 (range: 1–80) laparoscopic liver resections per surgical unit were performed in 2009. Patients stayed in hospital for a median of 7 days (range: 2–15 days) after uncomplicated open liver resection and a median of 4 days (range: 1–10 days) after uncomplicated laparoscopic liver resection. Only 28.0% of centres reported having experience with fast-track programmes in liver surgery. The majority considered the instigation of a randomized controlled trial or a prospective register comparing the outcomes of open and laparoscopic techniques to be necessary.

Conclusions

Worldwide dissemination of laparoscopic liver resection is substantial, although laparoscopic volumes are low in the majority of HPB centres. The adoption of enhanced recovery programmes in liver surgery is limited and should be given greater attention.     

Evaluation of an enhanced recovery protocol after pancreaticoduodenectomy in elderly patients

Background

Recent evidence has shown that enhanced recovery after surgery (ERAS) protocols decrease hospital stay following pancreaticoduodenectomy (PD). The aims of this study were to assess the feasibility and to evaluate the effect of introducing ERAS principles after PD in elderly patients.

Methods

Patients ≥75 years were defined as elderly. Comparison of postoperative outcome was performed between 22 elderly patients who underwent ERAS (elderly ERAS + patients) and a historical cohort of 66 elderly patients who underwent standard protocols (elderly ERAS-patients).

Results

The lowest adherence with ERAS among elderly patients was observed for starting a solid food diet within POD 4 (n = 7) and early drains removal (n = 2). The highest adherence was observed for post-operative glycemic control (n = 21), epidural analgesia (n = 21), mobilization (n = 20) and naso-gastric removal in POD 0 (n = 20). Post-operative outcomes did not differ between elderly ERAS+ and elderly ERAS- patients. In patients with an uneventful postoperative course, the median intention to discharge was earlier in elderly ERAS + patients as compared to the elderly ERAS- patients (4 days versus 8 days, P < 0.001).

Conclusion

An ERAS protocol following PD seems to be feasible and safe among elderly although it is not associated with improved postoperative outcomes.     

Initial experiences in robot-assisted middle pancreatectomy

Objectives

Initial results in robot-assisted middle pancreatectomy (MP) have been encouraging. However, data comparing outcomes of robot-assisted MP with those of open MP are limited. The aim of this study was to compare outcomes in patients undergoing open and robot-assisted MP, respectively.

Methods

Outcomes in an initial experience with seven consecutive patients undergoing robot-assisted MP were compared with those in 36 patients undergoing open MP.

Results

The robot-assisted MP group included five women and two men with a median age of 55 years (range: 30–62 years). Median tumour size, operative time and blood loss were 3.0 cm (range: 0.5–5.0 cm), 210 min (range: 150–330 min) and 200 ml (range: 50–400 ml), respectively. Pancreaticogastrostomy was performed in all patients. No transfusion was given intraoperatively. Pathological examination revealed five serous cystic neoplasms, one mixed-type intraductal papillary mucinous neoplasm and one lipoma. Five patients experienced postoperative pancreatic fistula and one experienced post-pancreatectomy haemorrhage. No operative mortality was noted. Compared with the open MP group, the robot-assisted MP group demonstrated a shorter median length of postoperative gastrointestinal tract recovery [2 days (range: 2–3 days) versus 4 days (range: 2–11 days); P = 0.001].

Conclusions

Robot-assisted MP can be performed safely with satisfactory efficacy; patients experienced faster gastrointestinal tract recovery compared with patients undergoing open surgery.     

Upper midline incision for liver resection

Objectives

The optimal incision for liver resection in living donors or patients with small tumours should be revisited. This study introduces the upper midline incision (UMI) above the umbilicus for various liver resections using a conventional open-surgery technique.

Methods

A retrospective study based on a prospectively collected database of 308 liver resections performed by a single surgeon was conducted to evaluate the feasibility, safety and applicability of the UMI.

Results

From September 2006 to September 2010, this incision was used successfully in 308 consecutive liver resections in all patients with tumours measuring ≤ 5 cm and all living donors without any extension of the incision. The median length of the incision was 16.4 cm (range: 12–20 cm).The median operating time was 189 min (range: 54–305 min). The median postoperative hospital stay was 8 days (range: 6–17 days). One patient died in the postoperative period from heart failure. All other patients fully recovered and returned to their previous level of activity. Over a median follow-up of 31 months (range: 20–68 months), 25 complications (8.1%) developed. Seven wound infections (2.3%) occurred with no incisional hernia.

Conclusions

The UMI can be used safely and effectively in conventional open surgery in various liver resections and should therefore be given priority as the first-line technique in living liver donors and patients with tumours measuring ≤ 5 cm.     

Surgery residency training programmes have greater impact on outcomes after pancreaticoduodenectomy than hospital volume or surgeon frequency

Background:

Hospital volume of pancreaticoduodenectomy (PD) and surgeon frequency of PD have been shown to impact outcomes. The impact of surgery residency training programmes after PD is unknown. This study was undertaken to determine the impact of surgery training programmes on outcomes after PD, as well as their importance relative to hospital volume and surgeon frequency of PD.

Methods:

The State of Florida Agency for Healthcare Administration Database was queried for patients undergoing PD during 2002–2007. Measures of outcome were compared for patients undergoing PD at centres with vs. without surgery residency training programmes.

Results:

A total of 2345 PDs were identified, of which 1478 (63%) were undertaken at training centres and 867 (37%) were performed at non-training centres. Patients undergoing PD at training centres had shorter lengths of stay, lower hospital charges and lower in-hospital mortality. Relative to surgeon frequency of PD, training centres had a greater favourable impact on hospital length of stay, hospital charges and in-hospital mortality (P < 0.001 for each, ancova). Relative to hospital volume of PDs undertaken, training centres had a greater impact on hospital charges (P < 0.001, ancova).

Conclusions:

Surgery residency training programmes have a favourable effect on outcomes following PD and their impact on outcome is greater than the impact of hospital volume or surgeon frequency of PD.     

Short-term outcomes after liver resection for malignant and benign disease in the age of ERAS

Introduction

Enhanced Recovery After Surgery protocols have been implemented effectively after liver resection and provide benefits in terms of general morbidity rates. In order to optimise peri-operative care protocols and minimise morbidity, further investigation is required to identify factors associated with poor outcome after liver resection.

Methods

A retrospective analysis of patients undergoing liver resection and enhanced recovery care between January 2006 and September 2012 was conducted. Data were collected on patient outcome and demographics, operative and pathological details. Univariate and multivariate analyses were performed to determine independent predictors of adverse outcome.

Results

603 patients underwent liver resection during the study period. Morbidity and mortality rates were 34.3% and 1.5% respectively. The only predictor of major morbidity was extended resection (OR 4.079; 95% CI 2.177–7.642).

Conclusions

Extended resection is associated with major morbidity. When determining optimum peri-operative care, ERAS protocols must incorporate care components that can mitigate against morbidity associated with extended resection.     

A prospective cohort study of intrathecal versus epidural analgesia for patients undergoing hepatic resection

Background

The aim of this prospective observational study was to compare peri/post-operative outcomes of thoracic epidural analgesia (TEA) versus intrathecal morphine and fentanyl patient-controlled analgesia (ITM+fPCA) for patients undergoing a hepatic resection (HR).

Method

Patients undergoing elective, one-stage, open HR for benign and malignant liver lesions, receiving central neuraxial block as part of the anaesthetic, in a high-volume hepato-pancreato-biliary unit, were included in the study. The primary outcome measure was post-operative length of stay (LoS).

Results

A total of 73 patients (36 TEA and 37 ITM+fPCA) were included in the study. The median (IQR) post-operative LoS was 13 (11–15) and 11 (9–13) days in the TEA and ITM+fPCA groups, respectively (P = 0.011). There was significantly lower median intra-operative central venous pressure (P < 0.001) and blood loss (P = 0.017) in the TEA group, and a significant reduction in the time until mobilization (P < 0.001), post-operative intra-venous fluid/vasopressor requirement (P < 0.001/P = 0.004) in the ITM+fPCA group. Pain scores were lower at a clinically significant level 12 h post-operatively in the TEA group (P < 0.001); otherwise there were no differences out to day five. There were no differences in quality of recovery or postoperative morbidity/mortality between the two groups.

Conclusion

ITM+fPCA provides acceptable post-operative outcomes for HR, but may also increase the incidence of intra-operative blood loss in comparison to TEA.     

Hospital-based,acute care encounters after radiofrequency ablation of hepatic tumours

Background

The use of radiofrequency ablation (RFA) for cancer is increasing; however, post-discharge outcomes have not been well described. The aim of the present study was to determine rates of hospital-based, acute care utilization within 30 days of discharge after RFA.

Methods

Using state-level data from California, patients were identified who were at least 40 years of age who underwent RFA of hepatic tumours without a concurrent liver resection from 2007–2011. Our primary outcome was hospital readmissions or emergency department visits within 30 days of discharge. A multivariable regression model was constructed to identify patient factors associated with these events.

Results

The final sample included 1764 patients treated at 100 centres. Hospital readmissions (11.3/100 discharges), emergency department visits (6.0/100 discharges) and overall acute care utilization (17.3/100 discharges) were common. Most encounters occurred within 10 days of discharge for diagnoses related to the procedure. Patients with renal failure [adjusted odds ratio (AOR) = 1.98 (1.11–3.53)], obesity [AOR = 1.69 (1.03–2.77)], drug abuse [AOR = 2.95 (1.40–6.21)] or those experiencing a complication [AOR = 1.52 (1.07–2.15)] were more likely to have a hospital-based acute care encounter within 30 days of discharge.

Conclusions

Hospital-based acute care after RFA is common. Patients should be counselled regarding the potential for acute care utilization and interventions targeted to high-risk populations.     

Peri-operative outcomes for pancreatoduodenectomy in India: a multi-centric study

Background:

There have been an increasing number of reports world-wide relating improved outcomes after pancreatic resections to high volumes thereby supporting the idea of centralization of pancreatic resectional surgery. To date there has been no collective attempt from India at addressing this issue. This cohort study analysed peri-operative outcomes after pancreatoduodenectomy (PD) at seven major Indian centres.

Materials and Methods:

Between January 2005 and December 2007, retrospective data on PDs, including intra-operative and post-operative factors, were obtained from seven major centres for pancreatic surgery in India.

Results:

Between January 2005 and December 2007, a total of 718 PDs were performed in India at the seven centres. The median number of PDs performed per year was 34 (range 9–54). The median number of PDs per surgeon per year was 16 (range 7–38). Ninety-four per cent of surgeries were performed for suspected malignancy in the pancreatic head and periampullary region. The median mortality rate per centre was four (range 2–5%). Wound infections were the commonest complication with a median incidence per centre of 18% (range 9.3–32.2%), and the median post-operative duration of hospital stay was 16 days (range 4–100 days).

Conclusions:

This is the first multi-centric report of peri-operative outcomes of PD from India. The results from these specialist centers are very acceptable, and appear to support the thrust towards centralization.     

Prolonged postoperative length of stay is associated with poor overall survival after an esophagectomy for esophageal cancer

Background

To investigate the impact of prolonged length of stay (LoS) on long-term mortality in patients who have undergone curative resection for esophageal cancer (EC).

Methods

Between January 2001 and December 2009, patients who underwent an esophagectomy for EC at Fudan University Shanghai Cancer Center were enrolled in this study. We retrospectively analyzed the medical charts of all of the enrolled patients. To determine the effect of postoperative LoS on long-term survival, we separated the patients into three groups based on the lengths of their postoperative LoS, including an LoS of less than 2 weeks (Group 1, ≤2 W), an LoS between 2 and 3 weeks (Group 2, ≤3 W) and an LoS of more than 3 weeks (Group 3, >3 W). Perioperative and long-term outcomes were compared between the groups.

Results

In total, 348 patients were included in this study. All of the patients underwent an esophagectomy with 3-field lymph node dissection (3FLND). The median postoperative hospital stay was 14 days (range: 8-153 days). Complications were observed in 123 patients (15.9% in Group 1 vs. 73.2% in Group 2 vs. 96.6% in Group 3, P<0.001). The median duration of follow-up was 39 months (range: 3-120 months). There were significant reductions in preventive adjuvant therapy (P=0.003) and postoperative salvage therapy (P<0.001) among the three groups. The 5-year survival rate was significantly different among the groups (43% vs. 36% vs. 29%, respectively, P=0.006). There was no difference in the 5-year disease-free survival rate among the three groups (23% vs. 21% vs. 19%, P=0.238).

Conclusions

Prolonged LoS was significantly associated with reduced rates of overall survival (OS). The insufficient administration of adjuvant therapy may partly account for these findings.     

Identification of risk categories for in pancreaticoduodenectomy based on diagnosis

Background

Studies of pancreaticoduodenectomy (PD) frequently overlook diagnosis as a variable when evaluating postoperative outcomes or generically group patients according to whether they have ‘benign’ or ‘malignant’ disease. Large multicentre studies comparing postoperative outcomes in PD stratified by diagnosis are lacking. The present study was conducted to verify the hypothesis that postoperative morbidity and length of stay (LoS) following PD vary by diagnosis and that patients may be grouped into low- and high-risk categories.

Methods

The database of the American College of Surgeons National Surgical Quality Improvement Program (ACS-NSQIP) was reviewed for all PDs performed during 2005–2011. Diagnoses were identified using ICD-9 codes and grouped based on the incidence of major morbidity. Univariate and multivariate analyses were utilized to assess the impact of diagnosis on PD outcomes.

Results

Of 5537 patients, those with pancreas cancer (n = 3173) and chronic pancreatitis (n = 485) experienced similar incidences of major morbidity (P = 0.95) and were grouped as having low-risk diagnoses. Patients with bile duct and ampullary (n = 1181), duodenal (n = 558) and neuroendocrine (n = 140) disease experienced similar levels of major morbidity (P = 0.78) and were grouped as having high-risk diagnoses. A high-risk diagnosis was identified as an independent risk factor for a prolonged LoS [odds ratio (OR) 1.67], organ space infection (OR 2.57), sepsis or septic shock (OR 1.83), and major morbidity (OR 1.70). Diagnosis did not predict readmission.

Conclusions

The high-risk diagnosis is independently associated with postoperative morbidity and prolonged LoS. Patients with PD should be stratified by diagnosis to more accurately reflect their risk for postoperative complications and the complexity of care they will require.     

Comparison of intraoperative versus delayed enteral feeding tube placement in patients undergoing a Whipple procedure

Background

The intraoperative placement of an enteral feeding tube (FT) during pancreaticoduodenectomy (PD) is based on the surgeon''s perception of need for postoperative nutrition. Published preoperative risk factors predicting postoperative morbidity may be used to predict FT need and associated intraoperative placement.

Methods

A retrospective review of patients who underwent PD during 2005–2011 was performed by querying the National Surgical Quality Improvement Program (NSQIP) database with specific procedure codes. Patients were categorized based on how many of 10 possible preoperative risk factors they demonstrated. Groups of patients with scores of ≤1 (low) and ≥2 (high), respectively, were compared for FT need, length of stay (LoS) and organ space surgical site infections (SSIs).

Results

Of 138 PD patients, 82 did not have an FT placed intraoperatively, and, of those, 16 (19.5%) required delayed FT placement. High-risk patients were more likely to require a delayed FT (29.3%) compared with low-risk patients (9.8%) (P = 0.026). The 16 patients who required a delayed FT had a median LoS of 15.5 days, whereas the 66 patients who did not require an FT had a median LoS of 8 days (P < 0.001).

Conclusions

In this analysis, subjects considered as high-risk patients were more likely to require an FT than low-risk patients. Assessment of preoperative risk factors may improve decision making for selective intraoperative FT placement.     

Appointment “no-shows” are an independent predictor of subsequent quality of care and resource utilization outcomes

BACKGROUND

Identifying individuals at high risk for suboptimal outcomes is an important goal of healthcare delivery systems. Appointment no-shows may be an important risk predictor.

OBJECTIVES

To test the hypothesis that patients with a high propensity to "no-show" for appointments will have worse clinical and acute care utilization outcomes compared to patients with a lower propensity.

DESIGN

We calculated the no-show propensity factor (NSPF) for patients of a large academic primary care network using 5 years of outpatient appointment data. NSPF corrects for patients with fewer appointments to avoid over-weighting of no-show visits in such patients. We divided patients into three NSPF risk groups and evaluated the association between NSPF and clinical and acute care utilization outcomes after adjusting for baseline patient characteristics.

PARTICIPANTS

A total of 140,947 patients who visited a network practice from January 1, 2007, through December 31, 2009, and were either connected to a primary care physician or to a primary care practice, based on a previously validated algorithm.

MAIN MEASURES

Outcomes of interest were incomplete colorectal, cervical, and breast cancer screening, and above-goal hemoglobin A1c (HbA1c) and low-density lipoprotein (LDL) levels at 1-year follow-up, and hospitalizations and emergency department visits in the subsequent 3 years.

KEY RESULTS

Compared to patients in the low NSPF group, patients in the high NSPF group (n=14,081) were significantly more likely to have incomplete preventive cancer screening (aOR 2.41 [2.19–.66] for colorectal, aOR 1.85 [1.65–.08] for cervical, aOR 2.93 [2.62–3.28] for breast cancer), above-goal chronic disease control measures (aOR 2.64 [2.22–3.14] for HbA1c, aOR 1.39 [1.15–1.67] for LDL], and increased rates of acute care utilization (aRR 1.37 [1.31–1.44] for hospitalization, aRR 1.39 [1.35–1.43] for emergency department visits).

CONCLUSIONS

NSPF is an independent predictor of suboptimal primary care outcomes and acute care utilization. NSPF may play an important role in helping healthcare systems identify high-risk patients.KEY WORDS: No-show, Identification of high-risk patients, Health disparities, Psychosocial issues in healthcare     

Preoperative anemia and postoperative outcomes after hepatectomy

Background

Preoperative anaemia is associated with adverse outcomes after surgery but outcomes after liver surgery specifically are not well established. We aimed to analyze the incidence of and effects of preoperative anemia on morbidity and mortality in patients undergoing liver resection.

Methods

All elective hepatectomies performed for the period 2005–2012 recorded in the American College of Surgeons'' National Surgical Quality Improvement Program (ACS-NSQIP) database were evaluated. We obtained anonymized data for 30-day mortality and major morbidity (one or more major complication), demographics, and preoperative and perioperative risk factors. We used multivariable logistic regression models to assess the adjusted effect of anemia, which was defined as (hematocrit <39% in men, <36% in women), on postoperative outcomes.

Results

We obtained data for 12,987 patients, of whom 4260 (32.8%) had preoperative anemia. Patients with preoperative anemia experienced higher postoperative major morbidity and mortality rates compared to those without anemia. After adjustment for predefined variables, preoperative anemia was an independent risk factor for postoperative major morbidity (adjusted OR 1.21, 1.09–1.33). After adjustment, there was no significant difference in postoperative mortality for patients with or without preoperative anemia (adjusted OR 0.88, 0.66–1.16).

Conclusion

Preoperative anemia is independently associated with an increased risk of major morbidity in patients undergoing hepatectomy. Therefore, it is crucial to readdress preoperative blood management in anemic patients prior to hepatectomy.     

Patterns of complications following intraoperative radiofrequency ablation for liver metastases

Background

Intraoperative radiofrequency ablation (IRFA) is added to surgery to obtain hepatic clearance of liver metastases. Complications occurring in IRFA should differ from those associated with wedge or anatomic liver resection.

Methods

Patients with liver metastases treated with IRFA from 2000 to 2010 were retrospectively analysed. Postoperative outcomes are reported according to the Clavien–Dindo system of classification.

Results

A total of 151 patients underwent 173 procedures for 430 metastases. Of these, 97 procedures involved IRFA plus liver resection and 76 involved IRFA only. The median number of lesions treated by IRFA was two (range: 1–11). A total of 123 (71.1%) procedures were carried out in patients who had received preoperative chemotherapy. The mortality rate was 1.2%. Thirty (39.5%) IRFA-only patients and 45 (46.4%) IRFA-plus-resection patients presented complications. Immediate complications (n = 4) were associated with IRFA plus resection. American Society of Anesthesiologists (ASA) class, previous abdominal surgery or hepatic resection, body mass index, number of IRFA procedures, portal pedicle clamping, total vascular exclusion and preoperative chemotherapy were not associated with a greater number of complications of Grade III or higher severity. Length of surgery >4 h [odds ratio (OR) 2.67, 95% confidence interval (CI) 1.1–6.3; P < 0.05] and an associated contaminating procedure (OR 3.72, 95% CI 1.53–9.06; P < 0.005) led to a greater frequency of complications of Grade III or higher.

Conclusions

Mortality and morbidity after IRFA, with or without resection, are low. Nevertheless, long interventions and concurrent bowel operations increase the risk for septic complications.
