Association of the Home Health Value-Based Purchasing Model With Quality, Utilization, and Medicare Payments After the First 5 Years.

Importance: The original Home Health Value-Based Purchasing (HHVBP) model provided financial incentives to home health agencies for quality improvement in 9 randomly selected US states. Objective: To evaluate quality, utilization, and Medicare payments for home health patients in HHVBP states compared with those in comparison states. Design, Setting, and Participants: This cohort study was conducted in 2021 with secondary data from January 2013 to December 2020. A difference-in-differences design and multivariate linear regression were used to compare outcomes for Medicare and Medicaid beneficiaries who received home health care in HHVBP states with those in 41 comparison states during 3 years of preintervention (2013-2015) and the subsequent 5 years (2016-2020). Exposures: Home health care provided by a home health agency in HHVBP states and comparison states. Main Outcomes and Measures: Utilization (unplanned hospitalizations, emergency department visits, skilled nursing facility [SNF] visits) for Medicare beneficiaries within 60 days of beginning home health, Medicare payments during and 37 days after home health episodes, and quality of care (functional status, patient experience) during home health episodes. Results: Among 34 058 796 home health episodes (16 584 870 beneficiaries; mean [SD] age of 76.6 [11.7] years; 60.5% female; 11.2% Black non-Hispanic; 79.5% White non-Hispanic) from January 2016 to December 2020, 22.6% were in HHVBP states and 77.4% were in non-HHVBP states. For the HHVBP and non-HHVBP groups, 60.4% and 61.0% of episodes were provided to female patients; 10.0% and 13.6% were provided to Black non-Hispanic patients, and 82.4% and 75.2% were provided to White non-Hispanic patients, respectively. Unplanned hospitalizations decreased by 0.15 percentage points (95% CI, -0.30 to -0.01) more in HHVBP states, a 1.0% decline compared with 15.7% at baseline. The use of SNFs decreased by 0.34 percentage points (95% CI, -0.40 to -0.27) more in HHVBP states, a 6.9% decline compared with the 4.9% baseline average. There was an association between HHVBP and a reduction in average Medicare payments per day of $2.17 (95% CI, -$3.67 to -$0.68) in HHVBP states, primarily associated with reduced inpatient and SNF services, which corresponded to an average annual Medicare savings of $190 million. There was greater functional improvement in HHVBP states than comparison states and no statistically significant change in emergency department use or most measures of patient experience. Conclusions and Relevance: In this cohort study, the HHVBP model was associated with lower Medicare payments that were associated with lower utilization of inpatient and SNF services, with better or similar quality of care.

Peritoneal Dialysis Patient Outcomes under the Medicare Expanded Dialysis Prospective Payment System.

BACKGROUND AND OBJECTIVES: Peritoneal dialysis (PD) use increased in the United States with the introduction of a new Medicare prospective payment system in January 2011 that likely reduced financial disincentives for facility use of this home therapy. The expansion of PD to a broader population and facilities having less PD experience may have implications for patient outcomes. We assessed the impact of PD expansion on PD discontinuation and patient mortality. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS: A prospective cohort study was conducted of patients treated with PD at 90 days of ESKD. Patients were grouped by study start date relative to the Medicare payment reform: prereform (July 1, 2008 to December 31, 2009; n=10,585), interim (January 1, 2010 to December 31, 2010; n=7832), and reform period (January 1, 2011 to December 31, 2012; n=18,742). Patient characteristics and facility PD experience were compared at baseline (day 91 of ESKD). Patients were followed for 3 years for the major outcomes of PD discontinuation and mortality using Cox proportional hazards models. RESULTS: Patient characteristics, including age, sex, race, ethnicity, rurality, cause of ESKD, and comorbidity, were similar or showed small changes across the three study periods. There was an increasing tendency for patients on PD to be treated in facilities with less PD experience (from 34% during the prereform period being treated in facilities averaging <14 patients on PD per year to 44% in the reform period). Patients treated in facilities with less PD experience had a higher rate of PD discontinuation than patients treated in facilities with the most experience (hazard ratio [HR], 1.16; 95% confidence interval [95% CI], 1.10 to 1.23 for the first versus fifth quintile of PD experience). Nevertheless, the risk of PD discontinuation fell during the late interim period (HR, 0.88; 95% CI, 0.82 to 0.95) and most of the reform period (from HR, 0.85; 95% CI, 0.79 to 0.91 to HR, 0.94; 95% CI, 0.87 to 1.01). Mortality risk was stable across the three study periods. CONCLUSIONS: In the context of expanding PD use and declining facility PD experience, the risk of PD discontinuation fell, and there was no adverse effect on mortality.

Does One Size Fit All With the Effects of Payment Reform? Dialysis Facility Payer Mix and Anemia Management Under the Expanded Medicare Prospective Payment System.

BACKGROUND: The effects of Medicare payment reforms aiming to improve the efficiency and quality of care by establishing greater financial accountability for providers may vary based on the extent and types of other coverage for their patient populations. Providers who are more resource constrained due to a less favorable payer mix face greater financial risks under such reforms. The impact of the expanded Medicare dialysis prospective payment system (PPS) on quality of care in independent dialysis facilities may vary based on the extent of higher payments from private insurers available for managing increased risks. OBJECTIVES: To evaluate whether anemia outcomes for dialysis patients in independent facilities differ under the Medicare PPS based on facility payer mix. DESIGN: We examined changes in anemia outcomes for 122,641 Medicare dialysis patients in 921 independent facilities during 2009-2014 among facilities with differing levels of employer insurance (EI). We performed similar analyses of facilities affiliated with large dialysis organizations, whose practices were not expected to change based on facility-specific payer mix. RESULTS: Among independent facilities, similar modeled trends in low hemoglobin for all 3 facility EI groups in 2009-2010 were followed by increased low hemoglobin during 2012-2014 for facilities with lower EI (P<0.01). Post-PPS standardized blood transfusion ratios were 9% higher for lower EI versus higher EI independent facilities (P<0.01). Among large dialysis organizations facilities, there was no divergence in low hemoglobin by payer mix under the PPS. CONCLUSIONS: There is evidence of poorer quality of care for anemia under the PPS in independent facilities with lower versus higher EI. Provider responses to payment reform may vary based on attributes such as payer mix that could have implications for health disparities.

Payment Reform and Health Disparities: Changes in Dialysis Modality under the New Medicare Dialysis Payment System.

OBJECTIVE: To evaluate the effect of the Medicare dialysis payment reform on potential disparities in the selection of peritoneal dialysis (PD) for the treatment of end-stage renal disease (ESRD). DATA SOURCES: Centers for Medicare & Medicaid Services (CMS) ESRD Medical Evidence Form, Medicare claims, and other CMS data for 2008-2013. STUDY DESIGN: We examined the association of patient age, race/ethnicity, urban/rural location, pre-ESRD care, comorbidities, insurance, and other factors with the selection of PD as initial dialysis modality across prereform (2008-2009), interim (2010), and postreform (2011-2013) time periods. PRINCIPAL FINDINGS: Selection of PD increased among diverse patient subgroups following the payment reform. However, the lower PD selection observed with older age, black race, Hispanic ethnicity, less pre-ESRD care, and Medicaid insurance before the reform largely remained in the initial postreform years. CONCLUSIONS: Despite recent growth in PD, there may be ongoing disparities in access to PD that have largely not been mitigated by the payment reform. There is potential for modifying provider financial incentives to achieve policy goals related to cost and quality of care. However, even with a substantial shift in financial incentives, separate initiatives to reduce existing disparities in care may be needed.

Real-Time Ventricular Fibrillation Amplitude-Spectral Area Analysis to Guide Timing of Shock Delivery Improves Defibrillation Efficacy During Cardiopulmonary Resuscitation in Swine.

BACKGROUND: The ventricular fibrillation amplitude spectral area (AMSA) predicts whether an electrical shock could terminate ventricular fibrillation and prompt return of spontaneous circulation. We hypothesized that AMSA can guide more precise timing for effective shock delivery during cardiopulmonary resuscitation. METHODS AND RESULTS: Three shock delivery protocols were compared in 12 pigs each after electrically induced ventricular fibrillation, with the duration of untreated ventricular fibrillation evenly stratified into 6, 9, and 12 minutes: AMSA-Driven (AD), guided by an AMSA algorithm; Guidelines-Driven (GD), according to cardiopulmonary resuscitation guidelines; and Guidelines-Driven/AMSA-Enabled (GDAE), as per GD but allowing earlier shocks upon exceeding an AMSA threshold. Shocks delivered using the AD, GD, and GDAE protocols were 21, 40, and 62, with GDAE delivering only 2 AMSA-enabled shocks. The corresponding 240-minute survival was 8/12, 6/12, and 2/12 (log-rank test, P=0.035) with AD exceeding GDAE (P=0.026). The time to first shock (seconds) was (median [Q1-Q3]) 272 (161-356), 124 (124-125), and 125 (124-125) (P<0.001) with AD exceeding GD and GDAE (P<0.05); the average coronary perfusion pressure before first shock (mm Hg) was 16 (9-30), 10 (6-12), and 3 (-1 to 9) (P=0.002) with AD exceeding GDAE (P<0.05); and AMSA preceding the first shock (mV·Hz, mean±SD) was 13.3±2.2, 9.0±1.6, and 8.6±2.0 (P<0.001) with AD exceeding GD and GDAE (P<0.001). The AD protocol delivered fewer unsuccessful shocks (ie, less shock burden) yielding less postresuscitation myocardial dysfunction and higher 240-minute survival. CONCLUSIONS: The AD protocol improved the time precision for shock delivery, resulting in less shock burden and less postresuscitation myocardial dysfunction, potentially improving survival compared with time-fixed, guidelines-driven, shock delivery protocols.

Use of an interactive, faith-based kiosk by congregants of four predominantly, african-american churches in a metropolitan area.

Chronic diseases are prevalent in ethnic communities. Churches represent a potent resource for targeted health promotion. A faith-based kiosk was developed as an informational tool and placed in four predominantly (>80%) African-American churches. Congregants were surveyed to describe kiosk-use, kiosk-user characteristics, health status, and self-reported behavior changes attributed to the kiosk. We analyzed 1,573 questionnaires. Mean age of respondents was 46.4 years and >70% were women. "Older" congregations (mean age ≥46.1 years) had more reports of diabetes (p = 0.002) and heart diseases (p = 0.01) than younger churches (mean age ≤44.1), whereas asthma was more prevalent in the latter (p < 0.001). Prevalence of obesity (40%) was similar across churches (p = 0.570). Kiosk-use was reported by 420 (26.7%) respondents. Compared to non-users, kiosk-users were >40 years (p < 0.001), and reported >two health conditions, adjusted Odds Ratio (95% Confidence Interval) = 1.43 (1.0-2.0), p = 0.05. Male kiosk-users preferred to select disease-specific content, aOR = 1.87 (1.10-3.17), p = 0.02, while females tended to select information about supportive community resources, aOR = 0.49 (0.23-1.04), p = 0.062. Knowledge of kiosk-user characteristics and the "health status" of a congregation, provide an opportunity for targeted, church-based health promotion.

Transfusion of 1 and 2 units of red blood cells is associated with increased morbidity and mortality.

BACKGROUND: This study examined the relationship between transfusion of 1 or 2 units of red blood cells (RBCs) and the risk of morbidity and mortality after isolated on-pump coronary artery bypass grafting (CABG). METHODS: A total of 22,785 consecutive patients underwent isolated on-pump CABG between January 1, 2008, and December 31, 2011 in Michigan. We excluded 5,950 patients who received three or more RBC units. Twenty-one preoperative variables significantly associated with transfusion by univariate analysis were included in a logistic regression model predicting transfusion, and propensity scores were calculated. Transfusion and the propensity score covariate were included in additional logistic regression models predicting mortality and each of 11 postoperative outcomes. RESULTS: Operative mortality for the study cohort of 16,835 patients was 0.8% overall, 0.5% for the 10,884 patients with no transfusion, and 1.3% for the 5,951 patients who received transfusion of 1 or 2 units (odds ratio 2.44; confidence interval 1.74 to 3.42; p < 0.0001). The association between transfusion and mortality lessened after propensity adjustment but remained highly significant (odds ratio 1.86; confidence interval 1.21 to 2.87; p = 0.005). Of the 11 postoperative outcomes studied, all but sternal wound infection and need for dialysis were also significantly associated with transfusion. CONCLUSIONS: Transfusion of as little as 1 or 2 units of RBCs is common and is significantly associated with increased morbidity and mortality after on-pump CABG. The relationship persists after adjustment for preoperative risk factors. These results suggest that aggressive attempts at blood conservation and avoidance of even small amounts of RBC transfusion may improve outcomes after CABG.

Morbidity but not mortality is decreased after off-pump coronary artery bypass surgery.

BACKGROUND: Off-pump coronary bypass surgery (CABG) has been advocated to avoid the physiologic perturbations related to cardiopulmonary bypass and improve outcomes compared with on-pump CABG. Previous reports have been inconsistent, and thus its benefits remain uncertain. This retrospective study compared outcomes between on-pump and off-pump CABG from a large multicenter cohort of propensity-matched patients. METHODS: The study consisted of 21,640 patients (19,639 [90.8%] on-pump, 2,001 [9.2%] off-pump) who underwent isolated CABG between January 1, 2008, and June 30, 2011, and were entered into a statewide collaborative database. Univariate analysis compared 37 baseline characteristics between on-pump and off-pump procedures. Patients were matched 1:1 based on similarities in propensity scores derived from statistically significant baseline characteristics. Propensity scores and surgery type were used in conditional logistic regression models for predicting each of 14 postoperative outcomes using the sample of 3,898 matched procedures. RESULTS: Patients undergoing off-pump CABG had significantly fewer complications overall, including decreased red blood cell transfusion, stroke, intensive care unit and ventilator time, reoperation for bleeding, and length of stay. There was no difference in renal failure, wound infection, discharge location, or 30-day readmission rate. Although off-pump patients received fewer bypass grafts per patient (2.5 ± 1.2 versus 3.0 ± 1.1; p < 0.001), operative mortality was similar for the two groups (1.8% on-pump versus 2.3% off-pump; p = 0.30). CONCLUSIONS: Off-pump CABG was associated with less morbidity, shorter length of stay, and similar mortality compared with on-pump procedures, suggesting that it can be a safe and effective alternative to standard on-pump CABG. However, the limited use of off-pump CABG in this multicenter analysis may restrict the generalizability of these results, and realistically defines the limited degree of acceptance of this technique in a real-world environment.

Transfusion rate as a quality metric: is blood conservation a learnable skill?

BACKGROUND: Between January 2008 and December 2012, a multicenter quality collaborative initiated a focus on blood conservation as a quality metric, with educational presentations and quarterly reporting of institutional-level perioperative transfusion rates and outcomes. This prospective cohort study was undertaken to determine the effect of that initiative on transfusion rates after isolated coronary artery bypass grafting (CABG). METHODS: Between January 1, 2008, and December 31, 2012, 30,271 patients underwent isolated CABG in Michigan. Evaluated were annual crude and adjusted trends in overall transfusion rates for red blood cells (RBCs), fresh frozen plasma (FFP), and platelets, and in operative death. RESULTS: Transfusion rates continuously decreased for all blood products. RBC use decreased from 56.4% in 2008 (baseline) to 38.3% in 2012, FFP use decreased from 14.8% to 9.1%, and platelet use decreased from 20.5% to 13.4% (ptrend < 0.001 for all). A significant reduction occurred in deep sternal wound infection, reoperation for bleeding, renal failure, prolonged ventilation, initial ventilator time, and intensive care unit duration. The percentage of patients discharged home significantly increased (ptrend < 0.001). Mortality rates did not differ significantly (ptrend = 0.11). CONCLUSIONS: In a multicenter quality collaborative, increased attention to transfusion-related outcomes and blood conservation techniques, coincident with regular reporting and review of perioperative transfusion rates as a quality metric, was associated with a significant decrease in blood product utilization. These reductions were concurrent with significant improvement in most perioperative outcomes. This intervention was also safe, as it was not associated with any increases in mortality.

Adjuvant radiation therapy for patients with type II endometrial carcinoma: impact on tumor recurrence and survival.

PURPOSE/OBJECTIVE: The optimal adjuvant treatment of type II endometrial carcinoma after hysterectomy remains controversial. The objective of this study was to determine the effect of adjuvant radiation therapy (RT) on recurrence-free survival (RFS), disease-specific survival (DSS), and overall survival in patients with early-stage type II endometrial carcinoma. MATERIALS AND METHODS: In this institutional review board-approved study, our database of 1450 patients with endometrial cancer was reviewed. Seventy-nine surgically staged patients with 2009 International Federation of Gynecology and Obstetrics (FIGO) stages I and II serous and clear cell carcinoma were treated from 1991 to 2010. These patients were then divided into 2 groups; one group received adjuvant RT, and the other group included patients who did not receive adjuvant RT. RESULTS: The median age of the study cohort is 65 years, and the median follow-up is 47 months. Thirty-nine patients (49%) received adjuvant RT, and 40 patients did not. The 5-year RFS was significantly improved in patients who received RT (84% vs 58%; P = 0.002). Similarly, 5-year DSS was significantly improved in patients who received RT (87% vs 58%; P = 0.023) with a trend toward improved 5-year overall survival (74% vs 58%; P = 0.088). On multivariate analysis, lack of angiolymphatic invasion (P < 0.001 and P < 0.001), adjuvant RT (P < 0.001 and P = 0.004), and lack of lower uterine segment involvement (P = 0.007 and P = 0.009) were independent predictors of improved RFS and DSS, respectively. CONCLUSIONS: In the current study of surgically staged patients with type II endometrial carcinoma International Federation of Gynecology and Obstetrics stages I and II, adjuvant radiation therapy with or without chemotherapy resulted in a significant improvement in recurrence-free and disease-specific survival.

Significance of postoperative acute renal failure after continuous-flow left ventricular assist device implantation.

BACKGROUND: Deteriorating renal function is common in patients with advanced heart failure and is associated with poor outcomes. The relationship between renal function and left ventricular assist device (LVAD) implantation is complex and has been explored in multiple studies with contradictory results. The aim of our study is to examine the significance of postoperative renal failure after implantation of a continuous-flow LVAD and its relationship to outcomes. METHODS: From March 2006 to July 2011, 100 patients underwent implantation of a HeartMate II (Thoratec Corp, Pleasanton, CA) or HeartWare (Heart International, Inc, Framingham, MA) LVAD at our institution. Patients were stratified based on postoperative development of acute renal failure (ARF). Variables were compared using 2-sided t tests, χ(2) tests, Cox proportional hazards models, and log-rank tests to determine whether there was a difference between the 2 groups and whether postoperative renal failure was a significant independent predictor of outcome. RESULTS: We identified 28 patients (28%) with postoperative ARF and 72 patients (72%) without postoperative ARF. The 2 groups were similar with regard to demographics and comorbidities. The patients with ARF were more likely to be intubated preoperatively (14.3% versus 1.4%; p = 0.021) and had higher preoperative central venous pressure (CVP) (14.3 mm Hg versus 10.7 mm Hg; p = 0.015). Postoperatively patients with ARF had a longer hospital stay (32.4 versus 18.7; p = 0.05), were more likely to experience right ventricular (RV) failure (25% versus 5.6%; p = 0.01) and ventilator-dependent respiratory failure (VDRF) (28.6% versus 6.9%; p = 0.007). There was a significant difference when comparing the ARF and non-ARF groups for 30-day (17.9% versus 0%; p < 0.001), 180-day (28.6% versus 2.8%; p < 0.001), and 360-day mortality (28.6% versus 6.9%; p = 0.012). CONCLUSIONS: Patients in whom ARF developed after LVAD implantation had a higher rate of VDRF and RV failure and a longer length of stay (LOS). Postoperative ARF was associated with higher mortality at the 30-day, 180-day, and 360-day intervals. ARF after LVAD may be an early marker of poor outcome, particularly RV failure, and may be an opportunity for early intervention and rescue.

Is resternotomy a risk for continuous-flow left ventricular assist device outcomes?

BACKGROUND: The number of patients undergoing resternotomy continues to rise. Although catastrophic hemorrhage remains a dreaded complication, most published data suggest that sternal reentrance is safe, with negligible postoperative morbidity and mortality. A significant proportion of left ventricular assist device (LVAD) implantations are reoperative cardiac procedures. The aim of our study was to compare outcomes between first time sternotomy and resternotomy patients receiving continuous-flow LVADs, as a bridge to transplantation or destination therapy. METHODS AND MATERIALS: From March 2006 through February 2012, 100 patients underwent implantation of a HeartMate II or HeartWare LVAD at our institution. Patients were stratified into two groups, primary sternotomy and resternotomy. Variables were compared using two-sided t-tests, chi-square tests, Cox proportional hazards models, and log-rank tests to determine whether there was a difference between the two groups and if resternotomy was a significant independent predictor of outcome. RESULTS: We identified 29 patients (29%) who had resternotomy and 71 patients (71%) who had first time sternotomy. The resternotomy group was significantly older (56 years vs. 51 years, p = 0.05), was more likely to have ischemic cardiomyopathy (ICM) (69% vs. 30%, p < 0.001), chronic obstructive pulmonary disease (COPD) (31% vs. 14%, p = 0.05) and had longer cardiopulmonary bypass times (135 min vs. 100 min, p = 0.011). Survival rates at 30 days (93.1% vs. 95.8%, p = 0.564), 180 days (82.8% vs. 93%, p = 0.131), and 360 days (82.8% vs. 88.7%, p = 0.398) were similar for the resternotomy and primary sternotomy groups, respectively. Postoperative complications were also comparable, except for re-exploration for bleeding which was higher for the resternotomy group (17.2% vs. 4.2%, p = 0.029), although blood transfusion requirements were not significantly different (1.4 units vs. 1.2 units, p = 0.815). Left and right heart catheterization measurements and echocardiographic (ECHO) findings after 1 and 6 months of LVAD therapy were similar between the two groups. CONCLUSIONS: Survival at 30, 180, and 360 days after LVAD implantation is similar between the resternotomy and primary sternotomy group. No major differences in complications or hemodynamic measurements were observed. Although a limited observational study, our findings agree with previously published resternotomy outcomes.

The impact of race on outcomes of patients with early stage uterine endometrioid carcinoma.

OBJECTIVES: The purpose of the present study was to determine whether racial disparity exists between African American (AA) and non-African American (NAA) patients with uterine endometrioid carcinoma who received similar multidisciplinary management. METHODS: We identified 766 patients with endometrioid adenocarcinoma 2009 FIGO stages I-II who underwent hysterectomy. Patients were divided into two groups; AA and NAA. Recurrence-free survival (RFS), disease specific survival (DSS) and overall survival (OS) for two groups were calculated. RESULTS: Median follow-up was 5.1 years. 27% were AA and 73% were NAA. All patients underwent hysterectomy and oophorectomy. 80% had peritoneal cytology examination and 69% underwent lymphadenectomy. AA patients were more likely to have higher grade tumors, and higher incidence of lymphovascular space involvement (LVSI). Although the two groups were balanced with regards to surgical staging and adjuvant treatment received, the 5-year RFS and DSS were significantly lower in AA compared to NAA patients (91% vs 84%, p=0.030; 95% vs 88%, p=0.011, respectively). Overall survival was not significantly different between the two groups. On multivariate analysis, after adjusting for other prognostic factors, race (AA vs NAA) was not a significant predictor of outcome. Grade 3 tumors and the presence of LVSI were the only two independent predictors of RFS and DSS with p ≤ 0.001 and p ≤ 0.001, respectively. CONCLUSION: In this large hospital-based study, AA race was associated with a higher incidence of adverse pathological features and worse recurrence-free and disease-specific survival. However, on multivariate analysis race was not an independent prognostic factor. Further studies are needed to elucidate possible underlying molecular mechanisms for these poorer outcomes.

Radiosurgery to the surgical cavity as adjuvant therapy for resected brain metastasis.

BACKGROUND: The standard treatment of resected brain metastasis is whole-brain radiotherapy (WBRT). To avoid the potential toxicity of WBRT and to improve local control, we have used radiosurgery alone to the surgical cavity. OBJECTIVE: To demonstrate the rates of local control, new intracranial metastasis, and overall survival using this treatment scheme without WBRT. METHODS: Eighty-five consecutive patients with brain metastasis were treated with surgical resection of at least 1 lesion followed by radiosurgery alone to the surgical cavity and any unresected lesions from August 2000 to March 2011. Sixty-eight percent had gross total resections. After surgery, radiosurgery was delivered to the surgical cavity with a 2- to 3-mm margin. The median marginal radiosurgery dose was 16 Gy, and median target volume was 13.96 cm. Follow-up imaging and clinical examination were obtained every 2 to 3 months. RESULTS: Median follow-up time was 11.2 months. Overall local control was 81.2%. The 6-month, 1-year, and 2-year rates of local control were 88.7%, 81.4%, and 75.7%, respectively. Forty-seven patients (55%) developed new intracranial metastases at a median time of 5.6 months. For the entire population, the rate of new metastases was 32.1%, 58.1%, and 62.9% at 6 months, 1 year, and 2 years, respectively. Median overall survival time was 12.1 months. From initial treatment until death or last follow-up, only 30 patients (35%) received WBRT as salvage treatment. CONCLUSION: Radiosurgery to the surgical cavity without WBRT achieved excellent local control of resected brain metastasis. Close imaging follow-up allows early intervention for any new metastasis.

Skin-of-color epidemiology: a report of the most common skin conditions by race.

To quantify and compare diagnoses according to race in pediatric Health Maintenance Organization (HMO) health plan patients seen in a general dermatology clinic over a 10-year period. Retrospective cohort of health plan pediatric patients seen in the dermatology clinic between 1997 and 2007 was established using an electronic medical record database. Diagnoses and diagnostic codes were recorded according to International Classification of Diseases, Ninth Revision (ICD-9) diagnostic codes grouped on their first three digits. The proportion of patients with each diagnosis was determined according to race and sex, and the 10 most common diagnoses were determined. The most common diagnoses observed in all pediatric patients were acne (28.6%), dermatitis (19.4%), and warts (16.2%), accounting for more than 60% of dermatologic visits by children. Although acne (29.9%), warts (22.6%), and dermatitis (13.1%) were also the most common diagnoses for Caucasian children, African American pediatric patients were most commonly seen for dermatitis (29.0%), acne (27.5%), and dermatophytosis (10.2%). The three most common diagnoses for Asian patients were dermatitis (29.1%), acne (22.2%), and warts (12.6%). Acne remains one of the most common dermatologic diagnoses in children of all races. Differences in frequency of office visits for dermatitis, warts, and dermatophytosis were seen when comparing children of other races with Caucasian children.

The prognostic significance of age in surgically staged patients with Type II endometrial carcinoma.

OBJECTIVE: Many studies have examined the impact of older age on tumor recurrence and survival after hysterectomy for patients with endometrioid carcinoma. However, there is paucity of data examining the prognostic significance of age in patients with Type II endometrial carcinoma. The study was conducted to determine the prognostic impact of age in this patient population. MATERIALS AND METHODS: In this Institutional Review Board (IRB)-approved study, our prospectively-maintained database of 1305 patients with endometrial cancer was reviewed. Seventy-two consecutive patients with serous and clear carcinoma 2009 FIGO stages I-II were identified with at least one year follow-up after surgical staging. Patients with mixed histology and those who received preoperative therapy were excluded. All the patients underwent surgical staging from 1989 to 2009. Their medical records were reviewed. The study cohort was divided into two groups based on their age at hysterectomy (≤ 65 vs. >65). Patient's demographics, pathologic features and treatment-related factors were compared. The impact of age on recurrence-free survival (RFS), disease-specific survival (DSS) and overall survival (OS) were calculated. Following univariate analysis, multivariate modeling was done using step-wise Cox proportional hazards analysis to assess the impact of age on clinical outcomes after adjusting for various clinical variables. RESULTS: Median follow-up for the study cohort was 45 months (range 13-246). Fifty percent of patients received adjuvant platinum-based chemotherapy and/or adjuvant radiation treatment (RT). Thirty-five patients were older than 65 years (49%) and 37 were ≤ 65 (51%). There were no significant differences between the two groups in regard to race (African American vs Caucasian), FIGO stage, number of lymph nodes dissected, lymphovascular space involvement (LVSI), or adjuvant therapy received. There were more clear cell histology in the younger age group (p=0.035). Patients >65 years old developed more recurrences with a 5-year RFS of 59% compared to 84% for younger patients (p=0.036). The five-year DSS was not statistically different between the two groups (68% vs. 79%, respectively with p=0.313). 5-year OS was significantly shorter in the elderly patients (58% vs. 78% with p=0.014). On multivariate analysis, the presence of LVSI, not receiving RT and age >65 were independent predictors of worse RFS (p=<0.001, 0.005, and 0.040 respectively). CONCLUSION: In this study for surgically staged FIGO I-II patients with Type II endometrial carcinoma, age more than 65 years is a significant adverse prognostic factor for tumor recurrence.

Preoperative predicted risk does not fully explain the association between red blood cell transfusion and mortality in coronary artery bypass grafting.

OBJECTIVE: Perioperative red blood cell transfusion is associated with increased morbidity and mortality after coronary artery bypass grafting (CABG). Whether transfusion is a cause of these outcomes or serves as a surrogate for a high-risk patient population remains uncertain. This retrospective study tested the hypothesis that increased preoperative risk profile of patients receiving transfusion would explain the relationship between red blood cell transfusion and operative mortality in isolated CABG. METHODS: A total of 31,818 patients undergoing isolated CABG were entered into a statewide collaborative database between January 2006 and June 2010. With the Society of Thoracic Surgeons risk calculator, patient cohorts were stratified into 4 groups by predicted risk of mortality (PROM) of less than 2%, 2% to 5%, more than 5% to 10% and more than 10%. The association between blood transfusion and mortality was tested at each stratum with a χ(2) test. A Breslow-Day test for homogeneity of odds ratios was used to test whether the 4 odds ratios of the strata were similar, and a Cochran-Mantel-Haenszel test was used to test the association between blood transfusion and mortality while controlling for predicted risk mortality strata. RESULTS: In all, 17,720 (55.7%) of all patients were transfused during the hospitalization. Incidence of transfusion increased stepwise with risk level; 93.3% of patients with PROM greater than 10% received blood. Operative mortality was 2.1% overall, 0.6% among the 44.3% of patients who were not transfused, and 3.3% in the transfused group (odds ratio, 6.19; P < .0001). The association between blood transfusion and mortality was significant within each predicted risk stratum. Increased mortality associated with transfusion was statistically equivalent across all predicted risk strata (P = .1778). The association between blood transfusion and mortality for all patients lessened somewhat when controlling for PROM (odds ratio, 2.99 vs 6.19), yet remained highly significant (P < .0001). CONCLUSIONS: The association between red blood cell transfusion and mortality after CABG is highly significant and independent of increased preoperative risk status. The correlation persists after controlling for increased PROM.

Distal pancreatectomy with or without splenectomy: comparison of postoperative outcomes and surrogates of splenic function.

OBJECTIVES: Published data on splenic preservation during distal pancreatectomy have been inconsistent. We hypothesized that patients undergoing spleen-preserving distal pancreatectomy (SPDP) would have fewer infectious and non-infectious complications than those undergoing en bloc distal pancreatectomy with splenectomy (DPS), and that their haematological parameters would be consistent with splenic function. METHODS: Of 97 patients who underwent either SPDP using the Warshaw technique or en bloc DPS, 78 met our study inclusion criteria. Records were reviewed for data on age, gender, resection, indications for resection, operative time, blood loss, transfusion requirements, hospital stay, infectious complications, any other complications, postoperative white blood cell (WBC) and platelet counts. Data were analysed using the chi-squared test, the two-sided Mann-Whitney-Wilcoxon text, and simple and multiple logistic regression analyses. A P-value of <0.05 was considered significant. RESULTS: Patients undergoing SPDP had a shorter length of stay and shorter operative time, were more likely to be completed laparoscopically, less likely to require re-operation, and had fewer infectious and non-infectious complications. However, these differences were not statistically significant. In multiple logistic regression analyses, patient age and length of hospital stay were both significant predictors of the occurrence of non-infectious complications (P= 0.04 and P= 0.006, respectively). Blood transfusion was a significant predictor of postoperative morbidity (P= 0.013 for infectious complications; P= 0.018 for non-infectious complications). White blood cell count was a statistically significant predictor of infectious (P= 0.02) and non-infectious (P= 0.04) complications, whereas platelet count was not. Patients who underwent DPS had statistically significantly higher WBC and platelet counts immediately postoperatively and at 6 months compared with SPDP patients. Postoperative mortality in both the SPDP and DPS groups was 0%. None of the 30 SPDP patients had evidence of splenic infarction. Pancreatic leaks occurred in 18% of patients in the SPDP group, compared with 8% in the DPS group (P < 0.05). CONCLUSIONS: Spleen-preserving distal pancreatectomy using the Warshaw technique is associated with lower postoperative morbidity than DPS. Lower WBC and platelet counts suggest better splenic function in SPDP patients.
