Development and validation of a tool to assess the readiness of a clinical teaching site for interprofessional education (InSITE).

Interprofessional education within clinical teaching sites is a key part of training for pre-professional students. However, the necessary characteristics of these interprofessional clinical teaching sites is unclear. We developed a tool, the Interprofessional Education Site Readiness, or InSITE, tool, for individuals at a site to use as a self-assessment of the site's current readiness for providing interprofessional education. The tool progressed through six stages of development, collecting evidence for validity and reliability, resulting in a final tool with 23 questions distributed across five domains. Data from 94 respondents from a variety of national sites were used for the item analysis showing acceptable item-to-total correlations. Internal reliability testing gave a Cronbach's coefficient alpha of more than 0.70 for each group level comparison. Known groups validity testing provides strong evidence for its responsiveness in detecting differences in sites where IPE is implemented. The results of the testing lead us to conclude that the InSITE tool has acceptable psychometric properties. Additionally, we discovered that the process in which the InSITE tool was used demonstrated that it can facilitate learning in practice for the health professionals and can help make implicit, informal workplace learning and the hidden curriculum explicit.

A Holistic Clustering Methodology for Liver Transplantation Survival.

BACKGROUND: Liver transplants account for a high number of procedures with major investments from all stakeholders involved; however, limited studies address liver transplant population heterogeneity pretransplant predictive of posttransplant survival. OBJECTIVE: The aim of the study was to identify novel and meaningful patient clusters predictive of mortality that explains the heterogeneity of liver transplant population, taking a holistic approach. METHODS: A retrospective cohort study of 344 adult patients who underwent liver transplantation between 2008 through 2014. Predictors were summarized severity scores for comorbidities and other suboptimal health states grouped into 11 body systems, the primary reason for transplantation, demographics/environmental factors, and Model for End Liver Disease score. Logistic regression was used to compute the severity scores, hierarchical clustering with weighted Euclidean distance for clustering, Lasso-penalized regression for characterizing the clusters, and Kaplan-Meier analysis to compare survival across the clusters. RESULTS: Cluster 1 included patients with more severe circulatory problems. Cluster 2 represented older patients with more severe primary disease, whereas Cluster 3 contained healthiest patients. Clusters 4 and 5 represented patients with musculoskeletal (e.g., pain) and endocrine problems (e.g., malnutrition), respectively. There was a statistically significant difference for mortality between clusters (p < .001). CONCLUSIONS: This study developed a novel methodology to address heterogeneous and high-dimensional liver transplant population characteristics in a single study predictive of survival. A holistic approach for data modeling and additional psychosocial risk factors has the potential to address holistically nursing challenges on liver transplant care and research.

The Interprofessional Collaborative Competency Attainment Survey (ICCAS): A replication validation study.

This study replicates a validation of the Interprofessional Collaboration Competency Attainment Survey (ICCAS), a 20-item self-report instrument designed to assess behaviours associated with patient-centred, team-based, collaborative care. We appraised the content validity of the ICCAS for a foundation course in interprofessional collaboration, investigated its internal (factor) structure and concurrent validity, and compared results with those obtained previously by ICCAS authors. Self-assessed competency ratings were obtained from a broad spectrum of pre-licensure, health professions students (n = 785) using a retrospective, pre-/post-design. Moderate to large effect sizes emerged for 16 of 20 items. Largest effects (1.01, 0.94) were for competencies emphasized in the course; the smallest effect (0.35) was for an area not directly taught. Positive correlations were seen between all individual item change scores and a separate item assessing overall change, and item-total correlations were moderate to strong. Exploratory factor analysis was used to understand the interrelationship of ICCAS items. Principal component analysis identified a single factor (Cronbach's alpha = 0.96) accounting for 85% of the total variance-slightly higher than the 73% reported previously. Findings suggest strong overlaps in the proposed constructs being assessed; use of a total average score is justifiable for assessment and evaluation.

Predictors of Liver Transplant Patient Survival.

OBJECTIVE: Liver transplantation is a costly and risky procedure, representing 25 050 procedures worldwide in 2013, with 6729 procedures performed in the United States in 2014. Considering the scarcity of organs and uncertainty regarding prognosis, limited studies address the variety of risk factors before transplantation that might contribute to predicting patient's survival and therefore developing better models that address a holistic view of transplant patients. This critical review aimed to identify predictors of liver transplant patient survival included in large-scale studies and assess the gap in risk factors from a holistic approach using the Wellbeing Model and the Strengthening the Reporting of Observational Studies in Epidemiology (STROBE) statement. DATA SOURCE: Search of the Cumulative Index to Nursing and Allied Health Literature (CINAHL), Medline, and PubMed from the 1980s to July 2014. STUDY SELECTION: Original longitudinal large-scale studies, of 500 or more subjects, published in English, Spanish, or Portuguese, which described predictors of patient survival after deceased donor liver transplantation. DATA EXTRACTION: Predictors were extracted from 26 studies that met the inclusion criteria. DATA SYNTHESIS: Each article was reviewed and predictors were categorized using a holistic framework, the Wellbeing Model (health, community, environment, relationship, purpose, and security dimensions). CONCLUSIONS: The majority (69.7%) of the predictors represented the Wellbeing Model Health dimension. There were no predictors representing the Wellbeing Dimensions for purpose and relationship nor emotional, mental, and spiritual health. This review showed that there is rigorously conducted research of predictors of liver transplant survival; however, the reported significant results were inconsistent across studies, and further research is needed to examine liver transplantation from a whole-person perspective.

The University of Minnesota Donor Lung Quality Index: A Consensus-Based Scoring Application Improves Donor Lung Use.

BACKGROUND: A simplified and consensus-based donor scoring process could improve donor lung use. METHODS: To develop the University of Minnesota Donor Lung Quality Index (UMN-DLQI), we used expert opinion to create an online survey that ranked 17 lung donor and recipient factors and graded their importance on a scale of 0 to 10. To arrive at consensus-based weights for each of the 17 factors, we used magnitude estimation (ME) methods. We performed receiver operating characteristic (ROC) analyses to evaluate predictive value. An application (app) was developed to simplify the scoring process. A second review process was instituted for every donor offer with an UMN-DLQI score greater than 40 as of September 2014 (post-donor score era). RESULTS: Worldwide, 11 transplantation centers (including ours) completed our survey. Results showed strong consensus among transplantation physicians across disparate practices. UMN-DLQI scores greater than 40 provided a sensitivity of 89%, a specificity of 55%, and a positive predictive value of 52% for donor offer acceptance. Number of transplants (63 versus 48) and donor lung use (15.1% versus 8.9%; p = 0.02) were significantly better in the post-donor score era without a penalty in transplantation outcomes. There was a trend toward a lower incidence of any primary graft dysfunction within 72 hours (40% versus 75%; p = 0.06) with a UMN-DLQI greater than 40 but no difference in 30-day or 1-year survival. CONCLUSIONS: The UMN-DLQI scoring app is a simple tool for describing the attributes of a donor lung offer. More attention to scores greater than 40 safely improved donor lung use at a single institution.

Learning by (video) example: a randomized study of communication skills training for end-of-life and error disclosure family care conferences.

BACKGROUND: Teaching residents to lead end of life (EOL) and error disclosure (ED) conferences is important. METHODS: We developed and tested an intervention using videotapes of EOL and error disclosure encounters from previous Objective Structured Clinical Exams. Residents (n = 72) from general and orthopedic surgery programs at 2 sites were enrolled. Using a prospective, pre-post, block group design with stratified randomization, we hypothesized the treatment group would outperform the control on EOL and ED cases. We also hypothesized that online course usage would correlate positively with post-test scores. RESULTS: All residents improved (pre-post). At the group level, treatment effects were insignificant, and post-test performance was unrelated to course usage. At the subgroup level for EOL, low performers assigned to treatment scored higher than controls at post-test; and within the treatment group, post graduate year 3 residents outperformed post graduate year ​1 residents. CONCLUSIONS: To be effective, online curricula illustrating communication behaviors need face-to-face interaction, individual role play with feedback and discussion.

Impact of early biliary complications on long-term outcomes in adult-to-adult living donor liver transplant recipients.

BACKGROUND: An adult-to-adult living donor liver transplant (LDLT) has emerged as a possible option to help alleviate the organ shortage. The aim of this study was to analyze our experience with biliary complications in LDLT recipients and to identify their risk factors for biliary complications. This paper aimed to describe therapeutic interventions and to evaluate the impact of biliary complications on long-term patient and graft survival rates. METHODS: We evaluated biliary complications in a cohort of 120 LDLT recipients at a single institution and studied the impact on long-term graft and patient survival. RESULTS: Of the 120 recipients, 26 (21.7%) developed biliary complications. Endoscopy was the initial choice of treatment for recipients with biliary complications. The median time for resolution of bile leaks was 37 days; for resolution of strictures, 82 days. A decreased risk of biliary complications was associated with an interrupted duct-to-duct (versus continuous choledocho-choledochostomy) (hazard ratio [HR]=0.22, P=0.002) and a Roux-en-Y hepaticojejunostomy (HR=0.13, P<0.001). In multivariate analysis of factors associated with graft failure and patient mortality, biliary complications were unrelated to long term (3 and 5 years) graft failure or patient mortality. CONCLUSIONS: In our study LDLT recipients had a 21.7% incidence of biliary complications, however, with successful endoscopic techniques, long-term patient and graft survival rates were not negatively affected.

Longterm health-related quality of life after living liver donation.

There are little data on longterm outcomes, health-related quality of life (HRQoL), and issues related to living donor right hepatectomy specifically. We studied longterm HRQoL in 127 living liver donors. A donor-specific survey (DSS) was used to evaluate the living liver donor morbidity, and the 36-item short-form health survey (short-form 36 health survey, version 1 [SF-36]) was used to assess generic outcomes. The DSS was completed by 107 (84.3%) donors and the SF-36 by 62 (49%) donors. Median follow-up was 6.9 years. Of the 107 donors, 12 (11.2%) donors reported their health as better, whereas 84 (78.5%) reported their health the same as before donation. Ninety-seven (90.7%) are currently employed. The most common postdonation symptom was incisional discomfort (34%). Twenty-four donors (22.4%) self-reported depression symptoms after donation. Ninety-eight (91.6%) rated their satisfaction with the donation process ≥ 8 (scale of 1-10). Three factors-increased vitality (correlation, 0.44), decreased pain (correlation, 0.34), and a recipient who was living (correlation, 0.44)-were independently related to satisfaction with the donor experience. Vitality showed the strongest association with satisfaction with the donor experience. Mental and physical component summary scale scores for donors were statistically higher compared to the US population norm (P < 0.001). Donors reported a high satisfaction rate with the donation process, and almost all donors (n = 104, 97.2%) would donate again independent of experiencing complications. Our study suggests that over a longterm period, liver donors continue to have above average HRQoL compared to the general population.

Factors Predicting Outcomes After a Total Pancreatectomy and Islet Autotransplantation Lessons Learned From Over 500 Cases.

OBJECTIVE: Our objective was to analyze factors predicting outcomes after a total pancreatectomy and islet autotransplantation (TP-IAT). BACKGROUND: Chronic pancreatitis (CP) is increasingly treated by a TP-IAT. Postoperative outcomes are generally favorable, but a minority of patients fare poorly. METHODS: In our single-centered study, we analyzed the records of 581 patients with CP who underwent a TP-IAT. Endpoints included persistent postoperative "pancreatic pain" similar to preoperative levels, narcotic use for any reason, and islet graft failure at 1 year. RESULTS: In our patients, the duration (mean ±â€ŠSD) of CP before their TP-IAT was 7.1 ±â€Š0.3 years and narcotic usage of 3.3 ±â€Š0.2 years. Pediatric patients had better postoperative outcomes. Among adult patients, the odds of narcotic use at 1 year were increased by previous endoscopic retrograde cholangiopancreatography (ERCP) and stent placement, and a high number of previous stents (>3). Independent risk factors for pancreatic pain at 1 year were pancreas divisum, previous body mass index >30, and a high number of previous stents (>3). The strongest independent risk factor for islet graft failure was a low islet yield-in islet equivalents (IEQ)-per kilogram of body weight. We noted a strong dose-response relationship between the lowest-yield category (<2000 IEQ) and the highest (≥5000 IEQ or more). Islet graft failure was 25-fold more likely in the lowest-yield category. CONCLUSIONS: This article represents the largest study of factors predicting outcomes after a TP-IAT. Preoperatively, the patient subgroups we identified warrant further attention.

Obstructive Sleep Apnea: A Risk Factor for Surgical Site Infection following Colectomy.

BACKGROUND: Obstructive sleep apnea (OSA) is associated with increased systemic oxidative stress, endothelial dysfunction, and activation of pro-inflammatory cascades, which increase host susceptibility to infection. OSA has not been evaluated as a risk factor for surgical site infection (SSI) following colectomy. We hypothesized that OSA increases the risk for SSI after colectomy. METHODS: We performed a retrospective review of 507 colectomies that took place between August 2011 and September 2013. Forty-two patients carried the diagnosis of OSA prior to surgery. These 42 patients were matched to 68 patients with no OSA for age, body mass index (BMI), diabetes mellitus (DM), reason for surgery and surgical approach. RESULTS: The rate of SSI was 28.6% (12 of 42) in the patients with and 10.3% (7 of 68) in the patients without OSA (p=0.03). Using logistic regression, the predictors of SSI following colectomy were found to be OSA (odds ratio [OR] of 3.98, 95% confidence interval [CI]=1.29-12.27), and DM (OR of 7.16, 95% CI=2.36-21.96). The average hospital stay after colectomy for patients with OSA complicated with SSI was 16.7 d whereas patients with OSA without SSI stayed 7.4 d (p<0.001). The rate of organ space infections was 9.5% (4 of 42) in the patients with OSA compared with 0 (p=0.02) in patients without OSA. CONCLUSIONS: OSA is an independent risk factor for SSI following colectomy. Patients with OSA have substantially greater rates of organ space SSI and longer hospital stay.

Translation of obesity practice guidelines: measurement and evaluation.

OBJECTIVE(S): A public health nurse (PHN) in the Midwestern United States (U.S.) led a collaborative system-level intervention to translate the Institute of Clinical Systems Improvement (ICSI) Adult Obesity Guideline into interprofessional practice. This study (1) evaluated the extent of guideline translation across organizations and (2) assessed the Omaha System as a method for translating system-level interventions and measuring outcomes. DESIGN AND SAMPLE: This retrospective, mixed methods study was conducted with a purposeful sample of one administrator (n = 10) and two to three clinicians (n = 29) from each organization (n = 10). MEASURES: Omaha System Problem Rating Scale for Outcomes Knowledge, Behavior, and Status (KBS). KBS ratings gathered from semi-structured interviews and Omaha System documentation were analyzed using standard descriptive and inferential statistics and triangulated findings with participant quotes. RESULTS: KBS ratings and participant quotes revealed intervention effectiveness in creating sustained system-level changes. Self-reported and observed KBS ratings demonstrated improvement across organizations. There was moderate to substantial agreement regarding benchmark attainment within organizations. On average, self-reported improvement exceeded observer improvement. CONCLUSIONS: System-level PHN practice facilitator interventions successfully translated clinical obesity guidelines into interprofessional use in health care organizations. The Omaha System Problem Rating Scale for Outcomes reliably measured system-level outcomes.

Time well spent: the association between time and effort allocation and intent to leave among clinical faculty.

PURPOSE: To explore the relationship between clinical faculty members' time/effort in four mission areas, their assessment of the distribution of that time/effort, and their intent to leave the institution and academic medicine. METHOD: Faculty from 14 U.S. medical schools participated in the 2011-2012 Faculty Forward Engagement Survey. The authors conducted multivariate logistic regression analyses to evaluate relationships between clinical faculty members' self-reported time/effort in each mission area, assessment of time/effort, and intent to leave the institution and academic medicine. RESULTS: Of the 13,722 clinical faculty surveyed, 8,349 (60.8%) responded. Respondents reported an average of 54.5% time/effort in patient care. The authors found no relationship between time/effort in patient care and intent to leave one's institution. Respondents who described spending "far too much/too much" time in patient care were more likely to report intent to leave their institution (odds ratio 2.12, P<.001). Those who assessed their time/effort in all mission areas as "about right" were less likely to report intent to leave their institution (64/1,135; 5.6%) than those who reported "far too little/too little" or "far too much/too much" time/effort in one or more mission areas (535/3,671; 14.6%; P<.001). CONCLUSIONS: Although the authors found no relationship between reported time/effort in patient care and intent to leave, the perception of "far too much/too much" time/effort spent in that mission area was correlated with intent to leave the institution. Efforts to align time/effort spent in each mission area with faculty expectations may improve retention.

Gastrointestinal symptoms before and after total pancreatectomy with islet autotransplantation: the role of pancreatic enzyme dosing and adherence.

OBJECTIVES: In a large cohort of subjects undergoing total pancreatectomy with islet autotransplantation (TPIAT), we assessed the prevalence and duration of gastrointestinal (GI) symptoms before and after the procedure to determine the impact of enzyme adherence on GI symptoms. METHODS: Three hundred fifty-six preoperative and postoperative questionnaires were collected from 184 subjects between ages of 5 and 66 years who underwent TPIAT between 2008 and 2011 at the University of Minnesota. Questionnaires were analyzed for self-reported frequency and severity of GI symptoms, pancreatic enzyme usage, and glycemic variability index (GVI). RESULTS: After surgery, patient-reported steatorrhea increased whereas constipation decreased. Gastrointestinal symptoms interfered with daily activity in 44% to 69% of subjects, before and after surgery, despite high reported enzyme adherence. Postoperatively, more than 79% of subjects reported consistent use of enzymes at all meals. Presence of GI symptoms did not vary with adherence. The GVI of 2 had a 2.8-fold increased odds of steatorrhea (95% confidence interval, 1.1-7.0) compared with GVI of 0. CONCLUSIONS: Gastrointestinal symptoms were common after TPIAT; ongoing management is needed. Enzyme nonadherence was not a major contributor to diarrhea/steatorrhea in this cohort. Glycemic variability was closely associated with steatorrhea; poor response to enzyme replacement may complicate diabetes management.

Near-euglycemia can be achieved safely in pediatric total pancreatectomy islet autotransplant recipients using an adapted intravenous insulin infusion protocol.

BACKGROUND: Children with severe chronic pancreatitis may undergo total pancreatectomy with islet autotransplantation (TPIAT) to relieve pain while minimizing the risk of postsurgical diabetes. Because overstimulation of transplanted islets by hyperglycemia can result in ß-cell loss, we developed a specialized intravenous insulin infusion protocol (IIP) for pediatric TPIAT recipients to maintain euglycemia or near-euglycemia posttransplant. SUBJECTS AND METHODS: Our objective was to review glucose control using an IIP specific for TPIAT recipients at a single institution. We reviewed postoperative blood glucose (BG) levels for 32 children 4-18 years old with chronic pancreatitis who underwent TPIAT between July 2011 and June 2013. We analyzed the proportion of BG values in the range of 70-140 mg/dL, mean glucose, glucose variability, and occurrence of hypoglycemia during the IIP; we also evaluated the transition to subcutaneous therapy (first 72 h with multiple daily injections [MDI]). RESULTS: During IIP, the mean patient BG level was 116±27 mg/dL, with 83.1% of all values in the range of 70-140 mg/dL. Hypoglycemia was rare, with only 2.5% of values <70 mg/dL. The more recent era (n=16) had a lower mean BG and less variability than the early era (first 16 patients) (P≤0.004). Mean glucose level (116 vs. 128 mg/dL) and glucose variability were significantly lower during the IIP compared with MDI therapy (P<0.0001). CONCLUSIONS: Tight glycemic control without excessive severe hypoglycemia was achieved in children undergoing TPIAT using an IIP specifically designed for this population; the ability to maintain BG in target range improved with experience with the protocol.

Engagement, workplace satisfaction, and retention of surgical specialists in academic medicine in the United States.

BACKGROUND: Academic medical centers strive for clinical excellence with operational efficiency and financial solvency, which requires institutions to retain productive and skillful surgical specialists. Faculty workplace perceptions, overall satisfaction, and intent to leave are relationships that have not been examined previously among US surgeons in academic medicine. We hypothesize that critical factors related to workplace satisfaction and engagement could be identified as important for enhancing institutional retention of academic surgeons. STUDY DESIGN: The 2011-2012 Association of American Medical Colleges Faculty Forward Engagement Survey evaluated demographic variables, physician workplace satisfaction, and overall engagement among faculty subgroups, including comparison of surgical and nonsurgical clinicians. Multiple regression analysis (ß = standard regression coefficient) was performed to identify critical factors most closely related to surgeon satisfaction and intent to leave their institutions. RESULTS: A total of 1,356 of 1,949 (70%) surgeons from 14 medical schools responded across different faculty subgroups, and comparisons were made with 1,105 nonsurgical clinicians. Multiple regression indicated that the strongest predictors of surgeons' overall satisfaction with their department included department governance (ß = 0.36; p < 0.001), collegiality and collaboration (ß = 0.23; p < 0.001), and relationship with supervisor (ß = 0.17; p < 0.001). Although compensation and benefits were important (ß = 0.08; p < 0.001), these did not rank as the most important factors. Promotion equality (odds ratio = 0.62; p < 0.05), collegiality and collaboration (odds ratio = 0 .51; p < 0.05), and nature of their work (odds ratio = 0.52; p < 0.05) were most closely related to intent to leave the medical school within 1 to 2 years. CONCLUSIONS: In the largest survey focusing on workplace factors affecting surgical faculty satisfaction and intent to leave, we conclude that institutional understanding of, and improvement in, specific work environment factors can enhance recruitment and retention of academic surgeons.

Long-term outcomes of total pancreatectomy and islet auto transplantation for hereditary/genetic pancreatitis.

BACKGROUND: Chronic pancreatitis is a debilitating disease resulting from many causes. The subset with hereditary/genetic pancreatitis (HGP) not only has chronic pain, but also an increased risk for pancreatic cancer. Long-term outcomes of total pancreatectomy (TP) and islet autogeneic transplantation (IAT) for chronic pancreatitis due to HGP are not clear. STUDY DESIGN: We reviewed a prospectively maintained database of 484 TP-IATs from 1977 to 2012 at a single center. The outcomes (eg, pain relief, narcotic use, ß-cell function, health-related quality of life measures) of patients who received TP-IAT for HGP (protease trypsin 1, n = 38; serine protease inhibitor Kazal type 1, n = 9; cystic fibrosis transmembrane conductance regulator, n = 14; and familial, n = 19) were evaluated and compared with those with non-hereditary/nongenetic causes. RESULTS: All 80 patients with HGP were narcotic dependent and failed endoscopic management or direct pancreatic surgery. Post TP-IAT, 90% of the patients were pancreatitis pain free with sustained pain relief; >65% had partial or full ß-cell function. Compared with nonhereditary causes, HGP patients were younger (22 years old vs 38 years old; p ≤ 0.001), had pancreatitis pain of longer duration (11.6 ± 1.1 years vs 9.0 ± 0.4 years; p = 0.016), had a higher pancreas fibrosis score (7 ± 0.2 vs 4.8 ± 0.1; p ≤ 0.001), and trended toward lower islet yield (3,435 ± 361 islet cell equivalent vs 3,850 ± 128 islet cell equivalent; p = 0.28). Using multivariate logistic regression, patients with non-HGP causes (p = 0.019); lower severity of pancreas fibrosis (p < 0.001); shorter duration of years with pancreatitis (p = 0.008); and higher transplant islet cell equivalent per kilogram body weight (p ≤ 0.001) were more likely to achieve insulin independence (p < 0.001). There was a significant improvement in health-related quality of life from baseline by RAND 36-Item Short Form Health Survey and in physical and mental component health-related quality of life scores (p < 0.001). None of the patients in the entire cohort had cancer of pancreatic origin in the liver or elsewhere develop during 2,936 person-years of follow-up. CONCLUSIONS: Total pancreatectomy and IAT in patients with chronic pancreatitis due to HGP cause provide long-term pain relief (90%) and preservation of ß-cell function. Patients with chronic painful pancreatitis due to HGP with a high lifetime risk of pancreatic cancer should be considered earlier for TP-IAT before pancreatic inflammation results in a higher degree of pancreatic fibrosis and islet cell function loss.

Islet size index as a predictor of outcomes in clinical islet autotransplantation.

BACKGROUND: The islet size distribution in a preparation may contribute to islet transplant outcomes. At the same islet equivalent (IE) dose, larger islets may exhibit poorer therapeutic value and this may be because of oxygen diffusion limitations that worsen in proportion to islet size. METHODS: To test this hypothesis, we studied the impact of islet size index (ISI) and other islet product characteristics on outcomes after islet autotransplant (IAT) in recipients receiving a marginal islet dose (2000-4999 IEs per kg body weight) from January 1, 2009 to June 11, 2012, at the University of Minnesota (n=58). ISI was defined as the number of IE divided by the number of islet particles (IPs) in a preparation; an ISI less than 1 indicates a mean islet diameter that is less than 150 µm. The primary post-IAT outcome was 6-month insulin use status. RESULTS: Logistic regression analysis indicate that IPs/kg (P=0.001), IEs/kg (P=0.019), total IPs transplanted (P=0.040), and ISI (P=0.074) were most strongly correlated with the primary outcome. The ISI (mean±standard error) was lower for recipients achieving insulin independence at 6 months (0.71±0.05) versus those partially (0.83±0.05) or completely (1.00±0.07) insulin dependent. The combination of islet dose (expressed as units IPs/kg) and ISI exhibited a sensitivity of 75% and specificity of 74% in predicting insulin independence in this population of patients. CONCLUSION: Islet autotransplant recipients of a marginal islet doses were more likely to achieve insulin independence when transplanted with a greater number of smaller islets.

Health-related quality of life: two decades after liver transplantation.

In this study, we describe a cohort of patients who received liver transplants before January 1, 1989 at the University of Minnesota Medical Center (UMMC), and we evaluate the health-related quality of life (HRQOL) of the survivors of this group. One hundred sixty-one patients--66 adults and 95 children--received whole deceased donor liver transplants. Thirteen transplants occurred before 1980, and all these patients died within 6 months; they were excluded from the survival analysis because they came from the pre-cyclosporine era. The survival rates at 1, 5, 10, and 20 years were 72%, 57%, 49%, and 37%, respectively (34% when pre-1980 patients were included). The median survival time was approximately 10 years for adult and pediatric recipients. The causes of death were ascertained by chart reviews. Technical failures were common between the years 1980 and 1984, and they decreased to 0% by 1988. As for HRQOL, 53 patients (36%) survived and were contacted to complete a 12-item health survey [Short Form 12 (SF-12)]. Retransplants were excluded. Sixty-eight percent returned the SF-12 survey. The median age for all respondents was 31.4 years: the median was 67.4 years for adult survivors and 28.8 years for pediatric survivors. The Mental Component Summary (MCS) score was 54.6 for adult survivors and 48.6 for pediatric survivors. The Physical Component Summary (PCS) score was 39.3 for adult survivors and 49.2 for pediatric survivors. Both the MCS and the PCS were norm-based to the US population with a mean of 50 and a standard deviation of 10. In conclusion, 35.8% of liver transplant recipients from UMMC were alive 20 years after liver transplantation. Technical failure-related deaths decreased dramatically from 1980 to 1988. The mental health of pediatric and adult survivors was similar to that of the general population. The physical health of the pediatric survivors was equivalent to that of the general population, but it was slightly less than what was expected with adjustments for age. The physical health of the adult survivors was approximately 1 standard deviation below that of the general population.

Total pancreatectomy and islet autotransplantation in children for chronic pancreatitis: indication, surgical techniques, postoperative management, and long-term outcomes.

OBJECTIVE: Describe the surgical technique, complications, and long-term outcomes of total pancreatectomy and islet autotransplantation (TP-IAT) in a large series of pediatric patients. BACKGROUND: Surgical management of childhood pancreatitis is not clear; partial resection or drainage procedures often provide transient pain relief, but long-term recurrence is common due to the diffuse involvement of the pancreas. Total pancreatectomy (TP) removes the source of the pain, whereas islet autotransplantation (IAT) potentially can prevent or minimize TP-related diabetes. METHODS: Retrospective review of 75 children undergoing TP-IAT for chronic pancreatitis who had failed medical, endoscopic, or surgical treatment between 1989 and 2012. RESULTS: Pancreatitis pain and the severity of pain statistically improved in 90% of patients after TP-IAT (P < 0.001). The relief from narcotics was sustained. Of the 75 patients undergoing TP-IAT, 31 (41.3%) achieved insulin independence. Younger age (P = 0.032), lack of prior Puestow procedure (P = 0.018), lower body surface area (P = 0.048), higher islet equivalents (IEQ) per kilogram body weight (P = 0.001), and total IEQ (100,000) (P = 0.004) were associated with insulin independence. By multivariate analysis, 3 factors were associated with insulin independence after TP-IAT: (1) male sex, (2) lower body surface area, and (3) higher total IEQ per kilogram body weight. Total IEQ (100,000) was the single factor most strongly associated with insulin independence (odds ratio = 2.62; P < 0.001). CONCLUSIONS: Total pancreatectomy and islet autotransplantation provides sustained pain relief and improved quality of life. The ß-cell function is dependent on islet yield. Total pancreatectomy and islet autotransplantation is an effective therapy for children with painful pancreatitis that failed medical and/or endoscopic management.

Challenges in academic obstetrics and gynecology departments.

OBJECTIVE: In 2011, the Association of American Medical Colleges conducted a multicenter survey to assess faculty satisfaction, engagement, and retention. This subanalysis describes the perceptions of academic obstetrician-gynecologists (ob-gyns). METHOD: Fourteen U.S. institutions offered voluntary faculty survey participation. We analyzed demographic information and responses to items within the 10 work-related dimensions. This analysis used pooled cohort data for 329 ob-gyn respondents across institutions. RESULTS: The mean response rate was 61.7% (9,600/15,570) overall and 66.9% for ob-gyn respondents. Most ob-gyn respondents reported satisfaction with work-related autonomy (72.2%) and a sense of accomplishment in their day-to-day activities (81.9%), including clarity about how their day-to-day activities fit into their medical school's mission (68.4%). In an average week, ob-gyn respondents reported working 59.4 hours on average. The mean percentage of effort varied by activity: patient care (54.8%), teaching (18.1%), research and scholarship (17.0%), and administration (15%). The mean proportion of ob-gyn respondents reporting that far too much or too much of their time and effort was spent on patient care was 35.1%, with more than half (59.5%) reporting far too little or too little of their time and effort was spent on research and scholarship and a third (33.3%) reporting far too little or too little time and effort devoted to teaching. Although 60.9% of respondents thought a mentor at their institution was important, only 22.2% reported a formal mentoring relationship. In the next 1-2 years, 13.4% reported seriously planning or being undecided (18.8%) about leaving their medical school. CONCLUSION: Academic obstetrics and gynecology departments face challenges balancing faculty members' academic desires and clinical demands. LEVEL OF EVIDENCE: II.
