Impact of an electronic medium delivery of warfarin education in a low income, minority outpatient population: a pilot intervention study.

BACKGROUND: Warfarin is classified as a high-alert medication for ambulatory healthcare and safe guards for high-alert medications are necessary, including the practice of mandatory patient education. The high cost of hospitalizations related to adverse events combined with the average bleeding event rate of 7-8% in spite of routine patient education, suggests the importance of new approaches to standardized health education on warfarin. We sought to evaluate the impact of a warfarin educational video using an electronic tablet on patient knowledge and to determine patients' satisfaction with the use of an electronic tablet for educational purposes in outpatient clinics serving a low income, minority population. METHODS: A warfarin educational video delivered on an electronic tablet (iPad) was delivered at two pharmacist-managed anticoagulation clinics to uninsured patients whose annual income is equal or less than two hundred percent below the poverty level were offered. Patients (n = 18) completed a pre-video and post-video knowledge test on warfarin before and after viewing the warfarin educational video on an electronic tablet and a follow-up test to measure the retention of knowledge and a patient satisfaction survey at 60 days. The primary outcome was change in knowledge test scores. Other outcome measures included adherence rates, adverse events, time in therapeutic INR range, and patient-reported satisfaction scores. RESULTS: The majority of patients were uninsured men taking warfarin for atrial fibrillation (n = 5). The median scores at post-video knowledge test and follow-up knowledge test were significantly higher than that for the pre-knowledge test (12 (11-12) vs. 10(8-11), p < 0.001). The study group had a 'time in therapeutic INR' range of 56.3%, a rate of adverse events of 24.5%, and a self-reported adherence rate to warfarin of 94.1%. The majority of patients also had positive responses to the patient satisfaction survey. CONCLUSIONS: Patient education delivered via iPad to facilitate knowledge of medication can serve as a useful tool for educating patients about warfarin and warfarin therapy. Use of an electronic medium may be a unique way to provide standard medication education to patients. TRIAL REGISTRATION: The study was retrospectively registered with: NCT03650777 ; 9/18/18.

Relation of Vasoplegia in the Absence of Primary Graft Dysfunction to Mortality Following Cardiac Transplantation.

Vasoplegia following cardiac transplantation is associated with increased morbidity and mortality. Previous studies have not accounted for primary graft dysfunction (PGD). The definition of vasoplegia is based on pressor requirement at 48 hours, many PGD parameters may have normalized after the initial 24 hours on inotropes. We surmised that the purported negative effects of vasoplegia following transplantation may in part be driven by PGD. We reviewed 240 consecutive adult cardiac transplants at our center between 2012 and 2016. The severity of vasoplegia was evaluated as a risk factor for 1-year survival, and the analysis was repeated for the subgroup of 177 patients who did not develop PGD. Overall, 63 (26%) of patients developed mild, moderate, or severe PGD. In those without PGD, vasoplegia was associated with length of stay but not with short- or long-term mortality. Moderate and/or severe vasoplegia occurred in 35 (15%) patients and was associated with higher short-term mortality, length of stay, and PGD. Multivariate logistic regression identified body mass index ≥35 kg/m2, left ventricular assist device before transplantation, and use of extracorporeal membrane oxygenation as joint risk factors for vasoplegia. In patients without PGD, only left ventricular assist device before transplantation was associated with vasoplegia. In conclusion, our results show that, in the sizeable subgroup of patients with no signs of PGD, vasoplegia had a much more modest impact on post-transplant morbidity and no significant effect on 1- and 3-year survival. This suggests that PGD may be a confounder when assessing vasoplegia as a risk factor for adverse outcomes.

Donor predicted heart mass as predictor of primary graft dysfunction.

BACKGROUND: Concern over the hazards associated with undersized donor hearts has impeded the utilization of otherwise viable allografts for transplantation. Previous studies have indicated predicted heart mass (PHM) may provide better size matching in cardiac transplantation than total body weight (TBW). We investigated whether size-matching donor hearts by PHM is a better predictor of primary graft dysfunction (PGD) than matching by TBW. METHODS: Records of consecutive adult cardiac transplants performed between 2012 and 2016 at a single-center academic hospital were reviewed. We compared patients implanted with hearts undersized by ≥30% with those implanted with donor hearts matched for size (within 30%), and performed the analysis both for undersizing by PHM and for undersizing by TBW. The primary outcome was moderate/severe PGD within 24 hours, according to the 2014 International Society for Heart and Lung Transplantation consensus. Secondary outcome was 1-year survival. RESULTS: Of 253 patients, 21 (8%) and 30 (12%) received hearts undersized by TBW and PHM, respectively. The overall rate of moderate/severe PGD was 13% (33 patients). PGD was associated with undersizing if performed by PHM (p = 0.007), but not if performed by TBW (p = 0.49). One-year survival was not different between groups (log-rank, p > 0.8). Multivariate analysis confirmed that undersizing donor hearts by PHM, but not by TBW, was predictive of moderate/severe PGD (OR 3.3, 95% CI 1.3 to 8.6). CONCLUSIONS: Undersized donor hearts by ≥30% by PHM may increase rates of PGD after transplantation, confirming that PHM provides more clinically appropriate size matching than TBW. Better size matching may ultimately allow for expanding the donor pool.

Effect of delay in cord clamping 45 versus 60 s on very preterm singleton infants.

BACKGROUND: In the range of timing suggested by American College of Obstetricians and Gynecologists 30 to 60 s, preterm infants may potentially derive more short and long-term benefits with delayed cord clamping (DCC) for at least 60 s. However, there are concerns with longer resuscitation delay in this vulnerable population. OBJECTIVE: To compare the clinical consequences of 45 versus 60 s delay in umbilical cord clamping in singleton infants born between 230/7 to 316/7 weeks gestation. STUDY DESIGN: We implemented DCC process in very preterm singleton infants, initially for 45 s and later, modified the policy to increase the delay to 60 s. We compared the infants born and received DCC (n = 60) during the 45 s study period (DCC-45 cohort), from Aug.19, 2013, to Aug.18, 2014 to the infants born and received DCC (n = 63) during the 60 s study period (DCC-60 cohort), from Feb.1, 2015, to Jan.31, 2016. RESULTS: The incidence of necrotizing enterocolitis in DCC-60 cohort was 0% compared to 8% in the DCC-45 cohort (P = 0.02). Similarly, incidence of culture-positive sepsis was significantly lower in the DCC-60 cohort compared to DCC-45 cohort (8% versus 18%; P = 0.04). Incidence of mortality and other major morbidities were similar between both groups. Length of stay was significantly lower in DCC-60 cohort compared to DCC-45 cohort. CONCLUSION: DCC for 60 s in very preterm singleton infants was safe, feasible and not associated with any adverse maternal or neonatal short-term outcomes compared to DCC for 45 s.

Reoperative sternotomy is associated with primary graft dysfunction following heart transplantation.

OBJECTIVES: Prior sternotomy is associated with increased morbidity and mortality following heart transplantation. However, its effect on primary graft dysfunction (PGD), a major contributor to early mortality, is unknown. Herein, this effect is studied using the International Society for Heart and Lung Transplantation consensus definition for PGD. METHODS: Medical records of consecutive adult cardiac transplants between 2012 and 2016 were reviewed. Baseline characteristics, postoperative findings and 1-year survival were compared between patients with and without prior sternotomy. RESULTS: Among 255 total patients included, 139 (55%) had undergone prior sternotomy; these recipients were older, more often male, had higher body mass index, higher frequencies of united network for organ sharing (UNOS) 1A status and ischaemic cardiomyopathy and experienced longer waitlist times when compared with those without prior sternotomy (all P < 0.018). Postoperatively, the prior sternotomy group exhibited higher rates of mild to severe PGD (32% vs 18%; P = 0.015) and higher short-term mortality (P = 0.017) and 1-year mortality (P = 0.047). They required more blood transfusions, had more postoperative pneumonia, wound infection and longer hospital stays. A stepwise multivariable regression model identified prior sternotomy as a predictor of PGD (odds ratio 2.7). Multiple prior sternotomies was associated with even more UNOS 1A status, ischaemic cardiomyopathy and pneumonia. However, logistic modelling did not show a difference in the rate of PGD between those with 1 or ≥2 prior sternotomies. CONCLUSIONS: Our data suggest that prior sternotomy is a risk factor for PGD. Consistent with previous reports, prior sternotomy is associated with increased morbidity, blood product utilization and 1-year mortality following cardiac transplantation.

The effect of vertical split-flow patient management on emergency department throughput and efficiency.

BACKGROUND: To address emergency department overcrowding operational research seeks to identify efficient processes to optimize flow of patients through the emergency department. Vertical flow refers to the concept of utilizing and assigning patients virtual beds rather than to an actual physical space within the emergency department to care of low acuity patients. The aim of this study is to evaluate the impact of vertical flow upon emergency department efficiency and patient satisfaction. METHODS: Prospective pre/post-interventional cohort study of all intend-to-treat patients presenting to the emergency department during a two-year period before and after the implementation of a vertical flow model. RESULTS: In total 222,713 patient visits were included in the analysis with 107,217 patients presenting within the pre-intervention and 115,496 in the post-intervention groups. The results of the regression analysis demonstrate an improvement in throughput across the entire ED patient population, decreasing door to departure time by 17 min (95% CI 15-18) despite an increase in patient volume. No statistically significant difference in patient satisfaction scores were found between the pre- and post-intervention. CONCLUSIONS: Initiation of a vertical split flow model was associated with improved ED efficiency.

The Effect of Delayed Cord Clamping on Moderate and Early Late-Preterm Infants.

OBJECTIVE: This study aims to evaluate the clinical consequences of protocol-driven delayed umbilical cord clamping (DCC) implementation in moderate and early late-preterm (MELP) infants born between 320/7 and 346/7 weeks gestation. STUDY DESIGN: We conducted a prospective cohort study with a historic control cohort comparison. The prospective study period was 1 year when DCC was performed for 60 seconds duration (DCC cohort, n = 106). The study period for historic control cohort with no DCC was also 1 year before DCC implementation (historic cohort, n = 137). RESULTS: The mean hematocrit at birth was significantly higher in the DCC cohort compared with the historic cohort (49.1 ± 14.9 vs. 45.7 ± 15.7; p = 0.01). Fewer infants in the DCC cohort were admitted to neonatal intensive care unit (NICU) on respiratory support compared with the historic cohort (17.9 vs. 29.9%; p = 0.04). The incidence of respiratory distress syndrome was significantly lower in the DCC cohort compared with the historic cohort (2.8 vs. 14.6%; p = 0.002). There were no differences in the incidence of phototherapy or NICU length of stay (LOS) between groups. CONCLUSION: In MELP infants, DCC was associated with increased hematocrit and better respiratory transition at birth. DCC was not associated with increased phototherapy or NICU LOS.

Utilization of high donor sequence number grafts in cardiac transplantation.

Donor sequence number (DSN) represents the number of candidates to whom a graft was offered and declined prior to acceptance for transplantation. We sought to investigate the outcomes of patients receiving high DSN grafts. Consecutive isolated adult cardiac transplantations performed at a single-center were reviewed. Recipients were grouped into standard (≤75th percentile) DSN and high (>75th percentile) DSN. A previously validated donor risk index was used to quantify the risk associated with donor grafts, and recipient outcomes were assessed. Overall, 254 patients were included: 194 standard DSN (range 1-79) and 60 high DSN (range 82-1723). High DSN grafts were harvested at greater distance (P < .001) with increased ischemia time (P < .001), resulting in a modest increase in donor risk index (1 point median difference, P = .014). High DSN recipients were less frequently listed as UNOS status 1A (P < .001). Despite a nonsignificant trend toward increased in-hospital/30-day mortality in high DSN recipients, there were no differences in primary graft dysfunction or 1-year survival (high DSN 89% vs standard DSN 88%, P = .82). After adjustment for risk factors, high DSN was not associated with increased 1-year mortality (hazard ratio 1.18, 95%-CI 0.54-2.58, P = .68).

Salvage of severe primary graft dysfunction following heart transplantation using extracorporeal life support.

Primary graft dysfunction (PGD) is the leading cause of early mortality after heart transplantation. Typically, mechanical circulatory support is necessary to provide hemodynamic support and to enable graft recovery. However, both the reported incidence of PGD and the reported salvage rates with extracorporeal membrane oxygenation (ECMO) vary widely. This may partly be due to variations in the definition of PGD and its levels of severity. We analyzed a prospectively maintained database of 255 transplant recipients at our institution to determine the effectiveness of ECMO support in those who develop severe PGD as defined by the International Society for Heart and Lung Transplantation consensus guidelines. Nineteen (7.5%) patients (aged 32-69 years) developed severe PGD and were treated with veno-arterial (VA) ECMO, which was initiated in the operating room at the time of transplant in most patients. The majority received VA ECMO through femoral cannulation. Two patients required veno-venous ECMO for respiratory support after VA ECMO separation. The 30-day in-hospital survival rate following transplantation was 63% (n = 12). In conclusion, ECMO proved to be a viable option for early hemodynamic support in patients with severe PGD and has become our preferred modality for mechanical circulatory support in these patients.

Comparison of Clinical Characteristics, Complications, and Outcomes in Recipients Having Heart Transplants <65 Years of Age Versus ≥65 Years of Age.

Advanced recipient age remains a limiting factor for heart transplant candidacy, with many centers reluctant to transplant older patients. Here, we report our experience with recipients aged ≥65 years compared with younger recipients in terms of baseline characteristics, intraoperative and immediate postoperative experiences, and post-transplant morbidity and survival. The main study outcome was primary graft dysfunction (PGD), which has not been widely studied in this population. Donor and recipient data from 255 heart transplantations performed between 2012 and 2016 were reviewed. Seventy (27%) recipients were ≥65 years and 185 were younger. The older group had a higher frequency of ischemic cardiomyopathy and more frequently had a previous sternotomy than the younger recipients (all p <0.007). We found no significant differences in post-transplant morbidity (intensive care unit and hospital stay, pneumonia, infections, reoperation for bleeding, stroke, renal failure, or in-hospital mortality; all p >0.12). One-year survival was also similar in the 2 groups (p = 0.88). The incidence of moderate or severe PGD was lower in the older group (6%) than in the younger group (16%; p = 0.037). Multivariate logistic regression found pretransplant creatinine and donor undersizing by predicted heart mass to be predictors of moderate to severe PGD, whereas recipient age ≥65 years was identified as protective against PGD in this cohort. In conclusion, our study showed comparable survival and outcomes in recipients ≥65 years of age with otherwise similar nutritional status and body mass composition.

Efficacy of acute care health care providers in cardiopulmonary resuscitation compressions in normal and obese adult simulation manikins.

Annually, over 350,000 persons require cardiopulmonary resuscitation (CPR), either in or outside of the hospital. With obesity a rising health issue in the United States, concerns exist regarding the efficacy of quality compressions for CPR in obese patients. The aims of this study were to determine if the compressions for three adult simulation manikins (normal, obese, and morbidly obese) met quality guidelines; to examine any differences in quality of chest compressions performed by health care providers between the three manikins; and to examine the effect of participant characteristics on the quality of chest compressions in obese and morbidly obese manikins. A randomized controlled design was used. Sixty-one health care providers performed chest compressions on the three simulation manikins. Results showed that performance on the normal-sized manikin was significantly better than that on both obese and morbidly obese manikins. Participant characteristics were significantly associated with quality of chest compressions. The effectiveness of compressions in obese and morbidly obese CPR recipients has yet to be determined.

Reducing Length of Stay, Direct Cost, and Readmissions in Total Joint Arthroplasty Patients With an Outcomes Manager-Led Interprofessional Team.

The purpose of this quality improvement project was to determine whether an outcomes manager-led interprofessional team could reduce length of stay and direct cost without increasing 30-day readmission rates in the total joint arthroplasty patient population. The goal was to promote interprofessional relationships combined with collaborative practice to promote coordinated care with improved outcomes. Results from this project showed that length of stay (total hip arthroplasty [THA] reduced by 0.4 days and total knee arthroplasty [TKA] reduced by 0.6 days) and direct cost (THA reduced by $1,020 per case and TKA reduced by $539 per case) were significantly decreased whereas 30-day readmission rates of both populations were not significantly increased.

Implementation of an Automatic Stop Order and Initial Antibiotic Exposure in Very Low Birth Weight Infants.

Objective To evaluate if an antibiotic automatic stop order (ASO) changed early antibiotic exposure (use in the first 7 days of life) or clinical outcomes in very low birth weight (VLBW) infants. Study Design We compared birth characteristics, early antibiotic exposure, morbidity, and mortality data in VLBW infants (with birth weight <= 1500 g) born 2 years before (pre-ASO group, n = 313) to infants born in the 2 years after (post-ASO, n = 361) implementation of an ASO guideline. Early antibiotic exposure was quantified by days of therapy (DOT) and antibiotic use > 48 hours. Secondary outcomes included mortality, early mortality, early onset sepsis (EOS), and necrotizing enterocolitis. Results Birth characteristics were similar between the two groups. We observed reduced median antibiotic exposure (pre-ASO: 6.5 DOT vs. Post-ASO: 4 DOT; p < 0.001), and a lower percentage of infants with antibiotic use > 48 hours (63.4 vs. 41.3%; p < 0.001). There were no differences in mortality (12.1 vs 10.2%; p = 0.44), early mortality, or other reported morbidities. EOS accounted for less than 10% of early antibiotic use. Conclusion Early antibiotic exposure was reduced after the implementation of an ASO without changes in observed outcomes.

Effects of Skin-to-Skin Care on Late Preterm and Term Infants At-Risk for Neonatal Hypoglycemia.

OBJECTIVE: The objective of this study was to evaluate the effects of prolonged skin-to-skin care (SSC) during blood glucose monitoring (12-24 hours) in late preterm and term infants at-risk for neonatal hypoglycemia (NH). STUDY DESIGN: We conducted a retrospective pre- and postintervention study. We compared late preterm and term infants at-risk for NH born in a 1-year period before the SSC intervention, May 1, 2013, to April 30, 2014 (pre-SSC) to at-risk infants born in the year following the implementation of SSC intervention, May 1, 2014, to April 30, 2015 (post-SSC). RESULTS: The number of hypoglycemia admissions to neonatal intensive care unit among at-risk infants for NH decreased significantly from 8.1% pre-SSC period to 3.5% post-SSC period (P = 0.018). The number of infants receiving intravenous dextrose bolus in the newborn nursery also decreased significantly from 5.9% to 2.1% (P = 0.02). Number of infants discharged exclusively breastfeeding increased from 36.4% to 45.7%, although not statistically significant (P = 0.074). CONCLUSION: This SSC intervention, as implemented in our hospital, was associated with a significant decrease in newborn hypoglycemia admissions to neonatal intensive care unit. The SSC intervention was safe and feasible with no adverse events.

The Utilization of Robotic Pets in Dementia Care.

BACKGROUND: Behavioral problems may affect individuals with dementia, increasing the cost and burden of care. Pet therapy has been known to be emotionally beneficial for many years. Robotic pets have been shown to have similar positive effects without the negative aspects of traditional pets. Robotic pet therapy offers an alternative to traditional pet therapy. OBJECTIVE: The study rigorously assesses the effectiveness of the PARO robotic pet, an FDA approved biofeedback device, in treating dementia-related symptoms. METHODS: A randomized block design with repeated measurements guided the study. Before and after measures included reliable, valid tools such as: RAID, CSDD, GDS, pulse rate, pulse oximetry, and GSR. Participants interacted with the PARO robotic pet, and the control group received standard activity programs. Five urban secure dementia units comprised the setting. RESULTS: 61 patients, with 77% females, average 83.4 years in age, were randomized into control and treatment groups. Compared to the control group, RAID, CSDD, GSR, and pulse oximetry were increased in the treatment group, while pulse rate, pain medication, and psychoactive medication use were decreased. The changes in GSR, pulse oximetry, and pulse rate over time were plotted for both groups. The difference between groups was consistent throughout the 12-week study for pulse oximetry and pulse rate, while GSR had several weeks when changes were similar between groups. CONCLUSIONS: Treatment with the PARO robot decreased stress and anxiety in the treatment group and resulted in reductions in the use of psychoactive medications and pain medications in elderly clients with dementia.

Midterm clinical outcomes following arthroscopic transosseous rotator cuff repair.

PURPOSE: Arthroscopic transosseous (TO) rotator cuff repair has recently emerged as a new option for surgical treatment of symptomatic rotator cuff tears. Limited data is available regarding outcomes using this technique. This study evaluated midterm clinical outcomes following a novel arthroscopic TO (anchorless) rotator cuff repair technique. MATERIALS AND METHODS: A consecutive series of 107 patients and 109 shoulders underwent arthroscopic TO (anchorless) rotator cuff repair for a symptomatic full-thickness tear. Pre and postoperative range of motion (ROM) was compared at an average of 11.8 months. Postoperative outcome scores were obtained at an average of 38.0 months. Statistical analysis was performed to compare pre and postoperative ROM data. Univariate analysis was performed using Student's t-test to compare the effect of other clinical characteristics on final outcome. RESULTS: Statistically significant improvements were noted in forward flexion, external rotation and internal rotation (P < 0.0001). Average postoperative subjective shoulder value was 93.7, simple shoulder test 11.6, and American Shoulder and Elbow Surgeons (ASES) score 94.6. According to ASES scores, results for the 109 shoulders available for final follow-up were excellent in 95 (87.1%), good in 8 (7.3%), fair in 3 (2.8%), and poor in 3 (2.8%). There was no difference in ROM or outcome scores in patients who underwent a concomitant biceps procedure (tenodesis or tenotomy) compared with those who did not. Furthermore, there was no significant difference in outcome between patients who underwent either biceps tenodesis or tenotomy. Age, history of injury preceding the onset of pain, tear size, number of TO tunnels required to perform the repair, and presence of fatty infiltration did not correlate with postoperative ROM or subjective outcome measures at final follow-up. Two complications and four failures were noted. CONCLUSIONS: Arthroscopic TO rotator cuff repair technique leads to statistically significant midterm improvement in ROM and satisfactory midterm subjective outcome scores with low complication/failure rates in patients with average medium-sized rotator cuff tears with minimal fatty infiltration. Further work is required to evaluate radiographic healing rates with this technique and to compare outcomes following suture anchor repair. LEVEL OF EVIDENCE: Level IV.

Effect of delayed cord clamping on very preterm infants.

OBJECTIVE: Despite significant proposed benefits, delayed umbilical cord clamping (DCC) is not practiced widely in preterm infants largely because of the question of feasibility of the procedure and uncertainty regarding the magnitude of the reported benefits, especially intraventricular hemorrhage (IVH) vs the adverse consequences of delaying the neonatal resuscitation. The objective of this study was to determine whether implementation of the protocol-driven DCC process in our institution would reduce the incidence of IVH in very preterm infants without adverse consequences. STUDY DESIGN: We implemented a quality improvement process for DCC the started in August 2013 in infants born at ≤32 weeks' gestational age. Eligible infants were left attached to the placenta for 45 seconds after birth. Neonatal process and outcome data were collected until discharge. We compared infants who received DCC who were born between August 2013 and August 2014 with a historic cohort of infants who were born between August 2012 and August 2013, who were eligible to receive DCC, but whose cord was clamped immediately after birth, because they were born before the protocol implementation. RESULTS: DCC was performed on all the 60 eligible infants; 88 infants were identified as historic control subjects. Gestational age, birthweight, and other demographic variables were similar between both groups. There were no differences in Apgar scores or admission temperature, but significantly fewer infants in the DCC cohort were intubated in delivery room, had respiratory distress syndrome, or received red blood cell transfusions in the first week of life compared with the historic cohort. A significant reduction was noted in the incidence of IVH in the DCC cohort compared with the historic control group (18.3% vs 35.2%). After adjustment for gestational age, an association was found between the incidence of IVH and DCC with IVH was significantly lower in the DCC cohort compared with the historic cohort; an odds ratio of 0.36 (95% confidence interval, 0.15-0.84; P < .05). There were no significant differences in deaths and other major morbidities. CONCLUSION: DCC, as performed in our institution, was associated with significant reduction in IVH and early red blood cell transfusions. DCC in very preterm infants appears to be safe, feasible, and effective with no adverse consequences.

Antibiotic utilization improvement with the Nanosphere Verigene Gram-Positive Blood Culture assay.

New technologies offer rapid identification of organisms and antimicrobial resistance markers in blood cultures several hours faster than conventional methods. We sought to determine whether implementation of the Verigene® Gram-Positive Blood Culture (BC-GP) assay paired with a well-defined results reporting algorithm would lead to earlier deescalation of empiric therapy for inpatients with methicillin-sensitive Staphylococcus aureus (MSSA) and vancomycin-resistant Enterococcus (VRE) bacteremia. The algorithm design focused on lessening the demand for pharmacist time by using electronic communications where possible. Our study compared inpatients with MSSA and VRE bacteremia from the time period before (pre-BC-GP) and after (post-BC-GP) implementation of the assay on June 25, 2013. The time from blood draw to identification and susceptibility results was decreased by 36.4 hours (P < 0.001) in the post-BC-GP group. The mean time from collection to the first dose of optimal antibiotics was reduced in the post-BC-GP group by 18.9 hours (P = 0.004) overall, with a 20.6-hour reduction (P = 0.009) for patients with MSSA and a 20.7-hour reduction (P = 0.077) for patients with VRE. Additionally, the percent of patients on empiric therapy who were placed on optimal antibiotics at any time after the Gram stain result was available increased from 64% (45/70) pre-BC-GP to 80% (43/54) post-BC-GP. The BC-GP led to an increased rate of deescalation of empiric antibiotics and a reduction in the time to optimal antibiotics for patients with MSSA and VRE bacteremia.

Virtual coaching for the high-intensity training of a powerlifter following coronary artery bypass grafting.

A 55-year-old powerlifter in Tennessee learned about the sport-specific, high-intensity cardiac rehabilitation training available in Dallas, Texas, and contacted the staff by phone. He was recovering from quadruple coronary artery bypass grafting (CABG) and had completed several weeks of traditional cardiac rehabilitation in his hometown, but the exercise program no longer met his needs. He wanted help in returning both to his normal training regimen and to powerlifting competition but was unable to attend the Dallas program in person. An exercise physiologist with the program devised a virtual coaching model in which the patient was sent a wrist blood pressure cuff for self-monitoring and was advised about exercises that would not harm his healing sternum, even as the weight loads were gradually increased. After 17 weeks of symptom-limited, high-intensity training that was complemented by phone and e-mail support, the patient was lifting heavier loads than he had before CABG. At a powerlifting competition 10 months after CABG, he placed first in his age group. This case report exemplifies the need for alternative approaches to the delivery of cardiac rehabilitation services.

Skin cancer evaluation in transplant patients: a physician opinion survey with recommendations.

BACKGROUND: Non-melanoma skin cancer is the most common malignancy in transplant patients. However, routine skin cancer evaluation is currently not the standard of care. OBJECTIVE: To investigate the current barriers among transplant physicians to skin cancer screening in their patients. To provide recommendations for appropriate routine skin surveillance. METHODS: A web-based survey was conducted among Baylor, Dallas transplant physicians. Thirty-seven of 46 responses were received, and 13 physicians (28%) were classified as "high screeners." RESULTS: The univariate analysis revealed three main barriers including the perception of difficulty in seeing a dermatologist (p = 0.017), skin cancer evaluation is not an important aspect of transplant care (p = 0.038), and thirdly, the belief that there is insufficient evidence to warrant universal skin cancer screening in transplant patients (p = 0.013). The fully adjusted multivariable analysis resulted in two significant conclusions; the most important predictor was the perceived lack of medical evidence for skin cancer screening. LIMITATIONS: The small sample size and all responses being from the same institution in Texas. CONCLUSION: The dermatologic evidence for regular skin cancer screening in transplant patients needs dissemination to our transplant colleagues. This is a significant practice gap which can be appropriately closed by integrating dermatologists into the transplant team.
