Patient and hospital characteristics on the variance of perioperative outcomes for pancreatic resection in the United States: a plea for outcome-based and not volume-based referral guidelines.
ABSTRACT There is an effect of patient and hospital characteristics on perioperative outcomes for pancreatic resection in the United States.
Retrospective cohort study.
Patient data from the Nationwide Inpatient Sample of the Healthcare Cost and Utilization Project from January 1988 to January 2003.
In-hospital mortality, perioperative complications, and mortality following a major complication.
A total of 103 222 patients underwent major pancreatic surgery. The annual number of pancreatic resections increased 15.0% during the 16-year study period. Resection for benign pancreatic disease increased 26.8%. Overall in-hospital mortality, perioperative complications, and mortality following a major complication were 6.5%, 35.6%, and 15.6%, respectively. Multivariate analysis demonstrated that significant independent predictors for these 3 perioperative outcomes were advancing age, male sex, medical comorbidity, and hospital volume for each type of pancreatic resection. The in-hospital mortality for pancreatoduodenectomy increases with age and ranges from 1.7% to 13.8% (P < .001). After adjusting for other confounders, the odds of in-hospital mortality for pancreatoduodenectomy, distal pancreatectomy, and total pancreatectomy in those 65 years or older were 4.78-fold, 3.84-fold, and 2.60-fold, respectively, lower in the high-volume hospitals compared with those in the lower-volume hospitals.
Perioperative complications derived from this population-based study were higher than those reported in many case series. A significant disparity was noted in perioperative outcomes among surgical centers across the United States. An outcome-based referral guideline may have an immediate effect on improving the quality of care in patients who undergo pancreatic resection for benign and malignant disease.

ABSTRACT: Objective: To optimize the results of low-volume (LV) centers for hepatopancreaticobiliary (HPB) surgery. Background: High-volume (HV) centers for HPB surgery have lower mortality than LV. Strategies for collaboration between HV and LV centers are not well investigated. Methods: Postoperative outcomes of patients undergoing curative HPB resection were evaluated at an LV hospital before (2006-2008) and during the collaboration (2009-2012) and at 2 hospitals with HV for either liver or pancreatic resection (2009-2012). Itinerant tutor surgeons from the HV centers were involved in the pre-, intra-and postoperative course of HPB patients at the LV hospital. Results: HPB cases at the LV center increased from 18 to 40 patients per year from 2006 to 2012, whereas 6-month postoperative mortality decreased from 17.8% (2006-2008) to 6% (2009-2012), P < 0.05 (liver: 10.3% vs 4.7% and pancreas: 29.4% vs 7.9%). During the collaborative study period, outcomes for hepatectomy were similar for LV and HV (85 vs 507 cases): postoperative Clavien-Dindo scores 4 and 5 were 2% and 0.2% for HV versus 2.4% and 1.2% for LV, respectively. Outcomes for pancreatic procedures (LV 63 vs HV 269 cases) showed better postoperative Clavien-Dindo scores 4 and 5 in the HV (0.7% score 4 and 1.5% score 5 for HV vs 3.2% and 6.3%, respectively, for LV) but the difference disappeared in the last 2 years (2011-2012) and matching the cases. Conclusions: Our partnership model helped improve postoperative outcomes at the LV center. Results at the LV hospital were comparable with the HV centers, although 2 years of partnership were required to achieve this in pancreatic surgery.Annals of Surgery 09/2014; DOI:10.1097/SLA.0000000000000975 · 7.19 Impact Factor

ABSTRACT: Among surgical oncology patients, incisional surgical site infection is associated with substantially increased morbidity, mortality and healthcare costs. Moreover, while adults undergoing pancreaticoduodenectomy with preoperative placement of an intrabiliary stent have a high risk of this type of infection, and wound protectors may significantly reduce its risk, no relevant studies of wound protectors yet exist involving this patient population. This study will evaluate the efficacy of a dual-ring wound protector for prevention of incisional surgical site infection among adults undergoing pancreaticoduodenectomy with preoperatively-placed intrabiliary stents.BMJ Open 08/2014; 4(8):e005577.

ABSTRACT: Numerous studies have recorded racial disparities in access to care for major cancers. We investigate contemporary national disparities in the quality of perioperative surgical oncological care using a nationally representative sample of American patients and hypothesize that disparities in the quality of surgical oncological care also exists. A retrospective, serial, and cross-sectional analysis of a nationally representative cohort of 3,024,927 patients, undergoing major surgical oncological procedures (colectomy, cystectomy, esophagectomy, gastrectomy, hysterectomy, pneumonectomy, pancreatectomy, and prostatectomy), between 1999 and 2009. After controlling for multiple factors (including socioeconomic status), Black patients undergoing major surgical oncological procedures were more likely to experience postoperative complications (OR: 1.24; p < 0.001), in-hospital mortality (OR: 1.24; p < 0.001), homologous blood transfusions (OR: 1.52; p < 0.001), and prolonged hospital stay (OR: 1.53; p < 0.001). Specifically, Black patients have higher rates of vascular (OR: 1.24; p < 0.001), wound (OR: 1.10; p = 0.004), gastrointestinal (OR: 1.38; p < 0.001), and infectious complications (OR: 1.29; p < 0.001). Disparities in operative outcomes were particularly remarkable for Black patients undergoing colectomy, prostatectomy, and hysterectomy. Importantly, substantial attenuation of racial disparities was noted for radical cystectomy, lung resection, and pancreatectomy relative to earlier reports. Finally, Hispanic patients experienced no disparities relative to White patients in terms of in-hospital mortality or overall postoperative complications for any of the eight procedures studied. Considerable racial disparities in operative outcomes exist in the United States for Black patients undergoing major surgical oncological procedures. These findings should direct future health policy efforts in the allocation of resources for the amelioration of persistent disparities in specific procedures.World Journal of Surgery 11/2014; 39(3).
