Abstract:
Few studies have compared outcomes of right colectomy (RC) and left colectomy (LC) with respect to both benign and malignant disease. The objective of this study was to compare outcomes of RC versus LC for benign and malignant disease using a national administrative database of academic medical centers. Using International Classification of Diseases, 9th Revision diagnosis and procedure codes, data was obtained from the University HealthSystem Consortium Clinical Data Base for patients that underwent RC and LC for benign and malignant disease between 2002 and 2006. The main outcomes compared were demographics, length of hospital stay, observed to expected in-hospital mortality, complications, 30-day readmission, and mean cost. There were a total of 27,483 patients; 12,971 patients (47.2%) underwent RC. Compared with LC for benign disease, RC was associated with a shorter length of stay, lower overall complications, lower wound infections, lower 30-day readmissions, and lower cost. Compared with LC for malignant disease, RC was associated with lower overall complications, lower wound infections, and lower cost. In this analysis of academic centers, RC was associated with a lower length of stay, lower morbidity, and lower cost when compared with LC for benign and malignant disease.

Abstract:
The emphasis on high-quality care has spawned the development of quality programs, most of which focus on broad outcome measures across a diverse group of providers. Our aim was to investigate the clinical outcomes for a department of surgery with multiple service lines of patient care using a relational database. Mortality, length of stay (LOS), patient safety indicators (PSIs), and hospital-acquired conditions were examined for each service line. Expected values for mortality and LOS were derived from University HealthSystem Consortium regression models, whereas expected values for PSIs were derived from Agency for Healthcare Research and Quality regression models. Overall, 5200 patients were evaluated from the months of January through May of both 2011 (n = 2550) and 2012 (n = 2650). The overall observed-to-expected (O/E) ratio of mortality improved from 1.03 to 0.92. The overall O/E ratio for LOS improved from 0.92 to 0.89. PSIs that predicted mortality included postoperative sepsis (O/E:1.89), postoperative respiratory failure (O/E:1.83), postoperative metabolic derangement (O/E:1.81), and postoperative deep vein thrombosis or pulmonary embolus (O/E:1.8). Mortality and LOS can be improved by using a relational database with outcomes reported to specific service lines. Service line quality can be influenced by distribution of frequent reports, group meetings, and service line-directed interventions.

Abstract:
Object The aim of this study was to evaluate the impact of a newly appointed neurointensivist on outcomes in head-injured patients in the neurological/neurosurgical intensive care unit (NICU). Methods The mortality rate, length of stay (LOS), and discharge disposition of all patients with head trauma who had been admitted to a 10-bed tertiary care university hospital NICU were compared between two 19-month periods, before and after the appointment of a neurointensivist. Data regarding these patients were collected using the hospital database and the University HealthSystem Consortium (UHC) database. Samples of medical records were reviewed for Glasgow Coma Scale (GCS) score documentation. The authors analyzed data pertaining to 328 patients before and 264 after the neurointensivist's appointment. The unadjusted mean in-hospital mortality rate increased 1.1% in the after period, but this increase was significantly lower compared with the UHC-based expected increase of 8.1% in the mortality rate during the same period (p < 0.0001). The unadjusted mean mortality rate in the NICU decreased from 13.4 to 12.9% (relative mortality rate reduction 4%) and the mean NICU LOS increased from 3.1 to 3.6 days (relative NICU LOS increase 16%), both nonsignificantly. A 51% reduction in the NICU-associated mortality rate (p = 0.01), a 12% shorter hospital LOS (p = 0.026), and 57% greater odds of being discharged to home or to rehabilitation (p = 0.009) were found in the after period in multivariate models after controlling for baseline differences between the two time periods. Better documentation of the GCS score by the NICU team was also found in the after period (from 60.4 to 82%, p = 0.02). Conclusions The institution of a neurointensivist-led team model had an independent, positive impact on patient outcomes, including a lower NICU-associated mortality rate and hospital LOS, improved disposition, and better chart documentation.

Abstract:
Use of laparoscopy in colorectal cancer surgery is still limited. The aim of this study was to determine the rate of use of laparoscopic colorectal surgery for cancer at academic medical centers and to evaluate if the site of surgery influences the rate of use. Clinical data of patients who underwent laparoscopic or open colon and rectal resections for cancer from 2007 to 2009 were obtained from the University HealthSystem Consortium database. Data concerning rate of laparoscopy, length of stay, morbidity, and risk-adjusted mortality were obtained. During the 36-month study period, 22,780 operations were performed. The overall rate for use of laparoscopy was 14.8 per cent. Laparoscopy was most often used for total colectomy (22.6%), sigmoid colectomy (17.3%), cecectomy (17.1%), and right hemicolectomy (17.0%). Laparoscopy was most infrequently used for abdominoperineal resection (8.0%), transverse colectomy (10.0%), and left hemicolectomy (13.1%). Length of stay for laparoscopic colon and rectal procedures was 3.2 days shorter than for open surgery. Although the benefits of laparoscopic colorectal surgery for cancer have been demonstrated, the use of laparoscopy for colorectal resection remains under 20 per cent for colon cancer and under 10 per cent for rectal cancer. Further studies are needed to determine the factors limiting the use of laparoscopy in colorectal surgery.

Abstract:
Objective.The incidence of invasive methicillin-resistant Staphylococcus aureus (MRSA) infections in the United States decreased during 2005–2008, but noninvasive community-associated MRSA (CA-MRSA) infections also frequently lead to hospitalization. We estimated the incidence of all MRSA infections among inpatients at US academic medical centers (AMCs) per 1,000 admissions during 2003–2008.Design.Retrospective cohort study.Setting and Participants.Hospitalized patients at 90% of nonprofit US AMCs during 2003–2008.Methods.Administrative data on MRSA infections from a hospital discharge database (University HealthSystem Consortium [UHC]) were adjusted for underreporting of the MRSA V09.0 International Classification of Diseases, Ninth Revision, Clinical Modification code and validated using chart reviews for patients with known MRSA infections in 2004–2005, 2006, and 2007.Results.The mean sensitivity of administrative data for MRSA infections at the University of Chicago Medical Center in three 12-month periods during 2004–2007 was 59.1%. On the basis of estimates of billing data sensitivity from the literature and the University of Chicago Medical Center, the number of MRSA infections per 1,000 hospital discharges at US AMCs increased from 20.9 (range, 11.1–47.7) in 2003 to 41.7 (range, 21.9–94.0) in 2008. At the University of Chicago Medical Center, among infections cultured more than 3 days prior to hospital discharge, CA-MRSA infections were more likely to be captured in the UHC billing-derived data than were healthcare-associated MRSA infections.Conclusions.The number of hospital admissions for any MRSA infection per 1,000 hospital admissions overall increased during 2003–2008. Use of unadjusted administrative hospital discharge data or surveillance for invasive disease far underestimates the number of MRSA infections among hospitalized patients.

Abstract:
High body mass index (BMI) has been shown to be a factor predictive of increased morbidity and mortality in several single-institution studies. Using the University HealthSystem Consortium clinical database, we examined the impact of BMI on in-hospital mortality for patients who underwent laparoscopic gastric bypass, sleeve gastrectomy, and gastric banding between October 2011 and February 2014. Outcomes were examined within each procedure according to BMI groups of 35 to 49.9, 50.0 to 59.9, and 60.0 kg/m2 or greater. Outcome measures included in-hospital mortality, major complications, length of hospital stay, 30-day readmission, and cost. A total of 40,102 bariatric procedures were performed during this time period. For gastric bypass, there was an increase of in-hospital mortality (0.01 and 0.02 vs 0.34%; P < 0.01) and major complications (0.93 and 0.99 vs 2.62%; P < 0.01) in the BMI 60 kg/m2 or greater group. In contrast, sleeve gastrectomy and gastric banding had no association between BMI and rates of mortality and major complications. Cost increased with increasing BMI groups for all procedures. A strong association was found between BMI 60 kg/m2 or greater and higher in-hospital mortality and major complication rates for patients who underwent laparoscopic gastric bypass but not in patients who underwent sleeve gastrectomy or gastric banding.

Abstract:
OBJECT The objective of this study was to compare the cost of deep brain stimulation (DBS) performed awake versus asleep at a single US academic health center and to compare costs across the University HealthSystem Consortium (UHC) Clinical Database. METHODS Inpatient and outpatient demographic and hospital financial data for patients receiving a neurostimulator lead implant (from the first quarter of 2009 to the second quarter of 2014) were collected and analyzed. Inpatient charges included those associated with International Classification of Diseases, Ninth Revision (ICD-9) procedure code 0293 (implantation or replacement of intracranial neurostimulator lead). Outpatient charges included all preoperative charges ≤ 30 days prior to implant and all postoperative charges ≤ 30 days after implant. The cost of care based on reported charges and a cost-to-charge ratio was estimated. The UHC database was queried (January 2011 to March 2014) with the same ICD-9 code. Procedure cost data across like hospitals (27 UHC hospitals) conducting similar DBS procedures were compared. RESULTS Two hundred eleven DBS procedures (53 awake and 158 asleep) were performed at a single US academic health center during the study period. The average patient age ( ± SD) was 65 ± 9 years old and 39% of patients were female. The most common primary diagnosis was Parkinson’s disease (61.1%) followed by essential and other forms of tremor (36%). Overall average DBS procedure cost was $39,152 ± $5340. Asleep DBS cost $38,850 ± $4830, which was not significantly different than the awake DBS cost of $40,052 ± $6604. The standard deviation for asleep DBS was significantly lower (p ≤ 0.05). In 2013, the median cost for a neurostimulator implant lead was $34,052 at UHC-affiliated hospitals that performed at least 5 procedures a year. At Oregon Health & Science University, the median cost was $17,150 and the observed single academic health center cost for a neurostimulator lead implant was less than the expected cost (ratio 0.97). CONCLUSIONS In this single academic medical center cost analysis, DBS performed asleep was associated with a lower cost variation relative to the awake procedure. Furthermore, costs compared favorably to UHC-affiliated hospitals. While asleep DBS is not yet standard practice, this center exclusively performs asleep DBS at a lower cost than comparable institutions.
