RESUMO
BACKGROUND AND OBJECTIVES: Despite the dramatic increase in the provision of virtual nephrology care, only anecdotal reports of outcomes without comparators to usual care exist in the literature. This study aimed to provide objective determination of clinical noninferiority of hybrid (telenephrology plus face-to-face) versus standard (face-to-face) inpatient nephrology care. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS: This retrospective study compares objective outcomes in patients who received inpatient hybrid care versus standard nephrology care at two Mayo Clinic Health System community hospitals. Outcomes were then additionally compared with those patients receiving care at another Mayo Clinic Health System site where only standard care is available. Hospitalized adults who had nephrology consults from March 1, 2020 to February 28, 2021 were considered. Regression was used to assess 30-day mortality, length of hospitalization, readmissions, odds of being prescribed dialysis, and hospital transfers. Sensitivity analysis was performed using patients who had ≥50% of their care encounters via telenephrology. Structured surveys were used to understand the perspectives of non-nephrology hospital providers and telenephrologists. RESULTS: In total, 850 patients were included. Measured outcomes that included the number of hospital transfers (odds ratio, 1.19; 95% confidence interval, 0.37 to 3.82) and 30-day readmissions (odds ratio, 0.97; 95% confidence interval, 0.84 to 1.06), among others, did not differ significantly between controls and patients in the general cohort. Telenephrologists (n=11) preferred video consults (82%) to phone for communication. More than half (64%) of telenephrologists spent less time on telenephrology compared with standard care. Non-nephrology hospital providers (n=21) were very satisfied (48%) and satisfied (29%) with telenephrology response time and felt telenephrology was as safe as standard care (67%), while providing them enough information to make patient care decisions (76%). CONCLUSIONS: Outcomes for in-hospital nephrology consults were not significantly different comparing hybrid care versus standard care. Non-nephrology hospital providers and telenephrologists had favorable opinions of telenephrology and most perceived it is as safe and effective as standard care.

BACKGROUND: Telenephrology has become an important health care delivery modality during the COVID-19 pandemic. However, little is known about patient perspectives on the quality of care provided via telenephrology compared to face-to-face visits. We aimed to use objective data to study patients' perspectives on outpatient nephrology care received via telenephrology (phone and video) versus face-to-face visits. METHODS: We retrospectively studied adults who received care in the outpatient Nephrology & Hypertension division at Mayo Clinic, Rochester, from March to July 2020. We used a standardized survey methodology to evaluate patient satisfaction. The primary outcome was the percent of patients who responded with a score of good (4) or very good (5) on a 5-point Likert scale on survey questions that asked their perspectives on access to their nephrologist, relationship with care provider, their opinions on the telenephrology technology, and their overall assessment of the care received. Wilcoxon rank sum tests and chi-square tests were used as appropriate to compare telenephrology versus face-to-face visits. RESULTS: 3,486 of the patient encounters were face-to-face, 808 phone and 317 video visits. 443 patients responded to satisfaction surveys, and 21% of these had telenephrology encounters. Established patients made up 79.6% of telenephrology visits and 60.9% of face-to-face visits. There was no significant difference in patient perceived access to health care, satisfaction with their care provider, or overall quality of care between patients cared for via telenephrology versus face-to-face. Patient satisfaction was also equally high. CONCLUSIONS: Patient satisfaction was equally high amongst those patients seen face-to-face or via telenephrology.

BACKGROUND: Prognostic information is key to shared decision-making, particularly in life-limiting illness like advanced chronic kidney disease (CKD). OBJECTIVE: To understand the prognostic information preferences expressed by older patients with CKD. DESIGN AND PARTICIPANTS: Qualitative study of 28 consecutively enrolled patients over 65 years of age with non-dialysis dependent CKD stages 3b-5, receiving care in a multi-disciplinary CKD clinic. APPROACH: Semi-structured telephone or in-person interviews to explore patients' preference for and perceived value of individualized prognostic information. Interviews were analyzed using inductive content analysis. KEY RESULTS: We completed interviews with 28 patients (77.7 ± SD 6.8 years, 69% men). Patients varied in their preference for prognostic information and more were interested in their risk of progression to end-stage kidney disease (ESKD) than in life expectancy. Many conflated ESKD risk with risk of death, perceiving a binary choice between dialysis and quick decline and death. Patients expressed that prognostic information would allow them to plan, take care of important business, and think about their treatment options. Patients were accepting of prognostic uncertainty and imagined leveraging it to nurture hope or motivate them to better manage risk factors. They endorsed the desire to receive prognosis of life expectancy even though it may be hard to accept or difficult to talk about but worried it could create helplessness for other patients in their situation. CONCLUSION: Most, but not all, patients were interested in prognostic information and could see its value in motivating behavior change and allowing planning. Some patients expressed concern that information on life expectancy might cause depression and hopelessness. Therefore, prognostic information is most appropriate as part of a clinical conversation that fosters shared decision-making and helps patients consider treatment risks, benefits, and burdens in context of their lives.

BACKGROUND: Approximately 750,000 people in the U.S. live with end-stage kidney disease (ESKD); the majority receive dialysis. Despite the importance of adherence to dialysis, it remains suboptimal, and one contributor may be patients' insufficient capacity to cope with their treatment and illness burden. However, it is unclear what, if any, differences exist between patients reporting high versus low treatment and illness burden. METHODS: We sought to understand these differences using a mixed methods, explanatory sequential design. We enrolled adult patients receiving dialysis, including in-center hemodialysis, home hemodialysis, and peritoneal dialysis. Descriptive patient characteristics were collected. Participants' treatment and illness burden was measured using the Illness Intrusiveness Scale (IIS). Participants scoring in the highest quartile were defined as having high burden, and participants scoring in the lowest quartile as having low burden. Participants in both quartiles were invited to participate in interviews and observations. RESULTS: Quantitatively, participants in the high burden group were significantly younger (mean = 48.4 years vs. 68.6 years respectively, p = <0.001). No other quantitative differences were observed. Qualitatively, we found differences in patient self-management practices, such as the high burden group having difficulty establishing a new rhythm of life to cope with dialysis, greater disruption in social roles and self-perception, fewer appraisal focused coping strategies, more difficulty maintaining social networks, and more negatively portrayed experiences early in their dialysis journey. CONCLUSIONS AND RELEVANCE: Patients on dialysis reporting the greatest illness and treatment burden have difficulties that their low-burden counterparts do not report, which may be amenable to intervention.

OBJECTIVE: To examine the association between continuous renal replacement therapy (CRRT) liberation and clinical outcomes among patients with acute kidney injury (AKI) requiring CRRT. METHODS: This single-center, retrospective cohort study included adult patients admitted to intensive care units with AKI and treated with CRRT from January 1, 2007, to May 4, 2018. Based on the survival and renal replacement therapy (RRT) status at 72 hours after the first CRRT liberation, we classified patients into liberated, reinstituted, and those who died. We observed patients for 90 days after CRRT initiation to compare the major adverse kidney events (MAKE90). RESULTS: Of 1135 patients with AKI, 228 (20%), 437 (39%), and 470 (41%) were assigned to liberated, reinstituted, and nonsurvival groups, respectively. The MAKE90, mortality, and RRT independence rates of the cohort were 62% (707 cases), 59% (674 cases), and 40% (453 cases), respectively. Compared with reinstituted patients, the liberated group had a lower MAKE90 (29% vs 39%; P=.009) and higher RRT independence rate (73% vs 65%; P=.04) on day 90, but without significant difference in 90-day mortality (26% vs 33%; P=.05). After adjustments for confounders, successful CRRT liberation was not associated with lower MAKE90 (odds ratio, 0.71; 95% CI, 0.48 to 1.04; P=.08) but was independently associated with improved kidney recovery at 90-day follow-up (hazard ratio, 1.81; 95% CI, 1.41 to 2.32; P<.001). CONCLUSION: Our study demonstrated a high occurrence of CRRT liberation failure and poor 90-day outcomes in a cohort of AKI patients treated with CRRT.

PURPOSE: No standardized criteria for continuous renal replacement therapy (CRRT) liberation have been established. We sought to develop and internally validate prediction models for successful CRRT liberation in critically ill patients with acute kidney injury (AKI). MATERIALS AND METHODS: This single-center, retrospective cohort study included adult patients admitted to intensive care units (ICUs) with AKI and treated with CRRT from January 1, 2007, to May 4, 2018, at a tertiary referral hospital. The cohort was randomly divided into derivation and validation sets. The outcomes were successful CRRT liberation, defined as renal replacement therapy (RRT)-free survival within 72 h after the liberation and hospital discharge. Multivariate logistic regression models were developed and internally validated. RESULTS: Of 1135 AKI patients requiring CRRT, successful CRRT liberation and RRT-free survival at hospital discharge were observed in 228 (20%) and 395 (35%) individuals, respectively. The independent predictors included mean hourly urine output within 12 h before liberation, mean serum creatinine value within 24 h before liberation, cumulative fluid balance from ICU admission to liberation, CRRT duration before liberation, and the requirement of vasoactive agents within 24 h before liberation. The models demonstrated good discrimination (AUROC, 0.76 and 0.78; positive predictive value, 36% and 48%; negative predictive value, 92% and 94%; respectively) and calibration in the validation set. CONCLUSIONS: These validated models could assist the decision-making related to the CRRT liberation in critically ill patients with AKI.

This study aimed to identify the time in therapeutic range (TTR) for dialysis patients on warfarin, and improve TTR with dietary review and intervention of interacting foods. We identified 151 patients undergoing hemodialysis in two units who were being treated with warfarin from January 1, 2010, through February 1, 2018, who were included in the overall TTR study. Of these, 15 patients were available to undergo the dietary intervention. International normalized ratio values were collected retrospectively for all eligible hemodialysis patients, and TTR was calculated for each period in which the patient was on hemodialysis. Patients who were available and agreed to the intervention underwent targeted dietician review of interacting foods, and their TTR post-treatment was calculated. The median (interquartile range [IQR]) TTR was 44 (IQR, 29 to 53) % among the 151 patients. Among the 15 patients who underwent the intervention, median (IQR) TTR was 52 (IQR, 32 to 56) pre-intervention and 51 (IQR, 38 to 69) post-intervention (P=0.53). TTR for dialysis patients is low in this overall cohort despite patients being seen at an integrated health care system. Focused improvement projects such as dietary review of interacting foods may help increase a patient's TTR.

BACKGROUND: Obstructive sleep apnea (OSA) is associated with increased risk of postoperative complications in noncardiac surgery, with limited literature on cardiac surgical patients. Perioperative outcomes of patients with OSA were compared with outcomes of those without OSA undergoing cardiac surgery. METHODS: This was a retrospective single-center cohort study of adults who underwent cardiac surgery from January 2010 to April 2017. Outcomes of patients with OSA were compared with those without OSA, including length of stay, readmissions, hospital death, and short-term outcomes. RESULTS: OSA was present in 2636 of 8612 patients (30.6%) identified during the study period with OSA. Patients with OSA had a longer median length of stay (6 vs 5 days, P < .001), longer incidence of prolonged (>7 days) length of stay (26.3% vs 23.0%, P < .001), and were less likely to be discharged to home (78.2% vs 84.4%, P < .001). OSA patients also had a higher 30-day readmission rate (14.7% vs 10.4%, P < .001). Acute kidney injury was more common in OSA patients (25.2% vs 19.9%, P < .001). Our multivariable model found postoperative atrial fibrillation was associated with older age and not OSA status (age <50 years compared with >75 years; odds ratio, 4.10; 95% confidence interval, 3.39-4.96). CONCLUSIONS: OSA patients had a longer mean length of stay, were more likely to have a prolonged length of stay, more likely to be discharged to a location other than home, and had a higher 30-day readmission rate. This suggests higher resource utilization is required to care for OSA patients after cardiac surgery.

The objective of this study is to describe the pharmacokinetics of lacosamide in a critically ill adult during continuous venovenous hemofiltration (CVVH). A 78-year-old male developed sepsis and acute kidney injury following cardiac surgery. He was initially treated with intermittent hemodialysis but developed nonconvulsive status epilepticus at the end of the first session and was subsequently initiated on CVVH. In addition to lorazepam boluses, levetiracetam, and midazolam infusion, he was loaded with lacosamide 400 mg intravenously and started on 200 mg intravenously twice daily as maintenance therapy. Noncompartmental modeling of lacosamide pharmacokinetics revealed significant extracorporeal removal, a volume of distribution of 0.69 L/kg, elimination half-life of 13.6 hours, and peak and trough concentrations of 7.4 and 3.7 mg/L, respectively (goal trough, 5-10 mg/L). We found significant extracorporeal removal of serum lacosamide during CVVH, which was higher than previously reported. This led to subtherapeutic concentrations and decreased overall antiepileptic drug exposure. The relationship between serum lacosamide concentrations and clinical efficacy is not well understood; thus, therapeutic drug monitoring is not routinely recommended. Yet, we demonstrated that measuring serum lacosamide concentrations in the critically ill population during continuous renal replacement therapy may be useful to individualize dosing programs. Further pharmacokinetic studies of lacosamide may be necessary to generate widespread dosing recommendations.

PURPOSE: To investigate early hemodynamic instability and its implications on adverse outcomes in patients who require continuous renal replacement therapy (CRRT). MATERIALS AND METHODS: A retrospective study of patients admitted to the intensive care unit (ICU) and underwent CRRT at Mayo Clinic, Rochester, Minnesota between December 2006 through November 2015. RESULTS: Multivariate logistic regression was performed to identify predictors of in-hospital mortality and major adverse kidney events (MAKE) at 90â¯days. Hypotension was defined as any of the following criteria occurring during the first hour of CRRT initiation: mean arterial pressureâ¯<â¯60â¯mmHg, systolic blood pressure (SBP) <90â¯mmHg or a decline in SBP >40â¯mmHg from baseline, a positive fluid balance >500â¯mL or increased vasopressor requirement. The analysis included 1743 patients, 1398 with acute kidney injury (AKI). In-hospital mortality occurred in 884 patients (51%). Early hypotension occurred in 1124 patients (64.6%) and remained independently associated with in-hospital mortality (OR 1.56, 95% CI: 1.25-1.9). CONCLUSION: Hypotension occurs frequently in patients receiving CRRT despite having a reputation as the dialysis modality with better hemodynamic tolerance. It is an independent predictor for worse outcomes. Further studies are required to understand this phenomenon.

INTRODUCTION: Overall survival of patients with end-stage renal disease (ESRD) remains poor. Oxidative stress is one of the major risk factors associated with mortality in this patient group. As glutathione S-transferases (GST) are well-established antioxidants, we hypothesized that a model including GST gene polymorphisms, oxidative damage byproducts and cell adhesion markers has a prognostic role in ESRD patient survival. METHODS: A prospective study of 199 patients with ESRD on haemodialysis was conducted. GST genotype, oxidative stress byproducts and cell adhesion molecules were measured in plasma. Multivariate Cox regression and Kaplan-Meier survival analyses were performed to test the predictive ability of these parameters in the 8-year follow-up period. RESULTS: GSTM1-null genotype was associated with significantly shorter overall (HR 1.6, p = 0.018) and cardiovascular-specific (HR 2.1, p = 0.010) survival. Oxidative stress byproducts (advanced oxidation protein products [AOPP], prooxidant-antioxidant balance [PAB], malondialdehyde [MDA]) and cell adhesion molecules (soluble vascular cell adhesion molecule-1 [sVCAM-1] and soluble intercellular adhesion molecule-1 [sICAM-1]) demonstrated a significant predictive role in terms of overall and cardiovascular survival. When 6 biomarkers (GSTM1 genotype, high AOPP/PAB/MDA/-sVCAM-1/sICAM-1) were combined into a scoring model, a significantly shorter overall and cardiovascular survival was observed for patients with the highest score (p < 0.001). CONCLUSION: We identified a novel panel of biomarkers that can be utilized in predicting survival in ESRD patients. This biomarker signature could enable better monitoring of patients and stratification into appropriate treatment groups.

Heparin-induced thrombocytopenia type II is a rare but devastating complication of heparin exposure. We review a case of a 66-year-old female who underwent aortic valve surgery requiring venoarterial extracorporeal membranous oxygenation (ECMO) support postoperatively. She subsequently developed acute renal failure due to bilateral renal vein thromboses and thrombocytopenia and was found to have platelet factor 4/heparin antibodies and was diagnosed with heparin-induced thrombocytopenia (HIT). She was transitioned to nonheparin anticoagulation and her thrombocytopenia improved. Although a rare complication of anticoagulation, diagnosing HIT in a patient on ECMO requires a high index of suspicion and should be considered.

Beriberi is a well-documented disease caused by thiamine deficiency. The diagnosis of gastrointestinal beriberi in the clinical setting is uncommon, especially in nonalcoholic patients. Failure to recognize beriberi can result in devastating acute multisystem organ failure; however, timely treatment can result in rapid improvement in a patient's clinical status. We present the case of an 81-year-old nonalcoholic man presenting with abdominal pain, lethargy, and hypotension. The patient was admitted to the intensive care unit and intubated for hemodynamic instability and declining mental status. Further investigations revealed profound lactic acidosis and cardiac hypokinesis. The patient's course changed rapidly after intravenous thiamine administration, and within hours he was weaned off vasopressors. He was extubated, discharged from the intensive care unit, and discharged to home quickly thereafter. To our knowledge, this report is the first description of gastrointestinal beriberi mimicking a surgical emergency in an otherwise well-nourished patient with no history of alcoholism. The rapid improvement the patient experienced with administration of thiamine underscores the importance of considering gastrointestinal beriberi and thiamine deficiency in all moribund patients with unexplained abdominal symptoms, cardiogenic shock, and lactic acidosis.
RESUMO
OBJECTIVE: Patients receiving dialysis are at increased risk for lower extremity amputations (LEAs) and postoperative morbidity. Limited studies have examined differences in 30-day outcomes of mortality and health care use after amputation or the preoperative factors that relate to worsened outcomes in dialysis patients. Our objective was to examine dialysis dependency and other preoperative factors associated with readmission or death after LEA. METHODS: A retrospective cohort study was conducted of dialysis-dependent and nondialysis patients undergoing major LEA in the 2012 to 2013 American College of Surgeons National Surgical Quality Improvement Program. Primary outcomes included death and hospital readmission within 30 days of amputation. RESULTS: Of 6468 patients, 1166 (18%) were dialysis dependent. The dialysis cohort had more blacks (39% vs 23%), diabetes (76% vs 58%), below-knee amputations (62% vs 55%), and in-hospital deaths (8% vs 3%; all P < .001). The 30-day postoperative death rates (15% vs 7%) and readmission rates (35% vs 20% per 30 person-days; both P < .001) were higher in dialysis patients. Among the live discharges, the rate of any readmission or death within 30 days from amputation was highest in those aged ≥50 years (40% per 30 person-days). Multivariable analyses in the dialysis cohort revealed increased age, above-knee amputation, decreased physical status, heart failure, high preoperative white blood cell count, and low platelet count to be associated with death (P < .05; C statistic, 0.75). The only preoperative factor associated with readmission in dialysis patients was race (P = .04; C statistic, 0.58). CONCLUSIONS: Readmission or death after amputation is increased among dialysis patients. Predicting which dialysis patients are at highest risk for death is feasible, whereas predicting which will require readmission is less so. Risk factor identification may improve risk stratification, inform reimbursement policies, and allow targeted interventions to improve outcomes.

BACKGROUND AND OBJECTIVES: Withdrawal from maintenance hemodialysis before death has become more common because of high disease and treatment burden. The study objective was to identify patient factors and examine the terminal course associated with hemodialysis withdrawal, and assess patterns of palliative care involvement before death among patients on maintenance hemodialysis. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS: We designed an observational cohort study of adult patients on incident hemodialysis in a midwestern United States tertiary center, from January 2001 to November 2013, with death events through to November 2015. Logistic regression models evaluated associations between patient characteristics and withdrawal status and palliative care service utilization. RESULTS: Among 1226 patients, 536 died and 262 (49% of 536) withdrew. A random sample (10%; 52 out of 536) review of Death Notification Forms revealed 73% sensitivity for withdrawal. Risk factors for withdrawal before death included older age, white race, palliative care consultation within 6 months, hospitalization within 30 days, cerebrovascular disease, and no coronary artery disease. Most withdrawal decisions were made by patients (60%) or a family member (33%; surrogates). The majority withdrew either because of acute medical complications (51%) or failure to thrive/frailty (22%). After withdrawal, median time to death was 7 days (interquartile range, 4-11). In-hospital deaths were less common in the withdrawal group (34% versus 46% nonwithdrawal, P=0.003). A third (34%; 90 out of 262) of those that withdrew received palliative care services. Palliative care consultation in the withdrawal group was associated with longer hemodialysis duration (odds ratio, 1.19 per year; 95% confidence interval, 1.10 to 1.3; P<0.001), hospitalization within 30 days of death (odds ratio, 5.78; 95% confidence interval, 2.62 to 12.73; P<0.001), and death in hospital (odds ratio, 1.92; 95% confidence interval, 1.13 to 3.27; P=0.02). CONCLUSIONS: In this single-center study, the rate of hemodialysis withdrawals were twice the frequency previously described. Acute medical complications and frailty appeared to be driving factors. However, palliative care services were used in only a minority of patients.

Routine preventive cancer screening is not recommended for patients with end-stage renal disease (ESRD) due to their limited life expectancy. The current extent of cancer screening in this population is unknown. Primary care (PC) reminder systems or performance incentives may encourage indiscriminate cancer screening. We compared rates of cancer screening in patients with ESRD, with and without PC visits. This is a retrospective cohort study using United States Renal Data System (USRDS) billing data and electronic medical record data. Patients aged ≥18â¯years starting dialysis from 2001 to 2008, Midwest regional dialysis network were categorized with or without a PC visit (defined as an office visit in family practice, internal medicine, pediatrics, geriatrics or preventive medicine during the first two years of dialysis). Cancer screening was based on Current Procedural Terminology codes in USRDS. We identified 2512 incident dialysis patients (60% men, median age 65y). Cancer screening rates were more frequent among those seen in PC: 38% vs 19% (Pâ¯=â¯0.0002), for breast; 18% vs 10% (Pâ¯=â¯0.047) for cervical; 13% versus 8% (Pâ¯=â¯0.024) for prostate; and 18% vs 9% (Pâ¯=â¯0.0002) for colon cancer. Multivariable analyses found that those with PC were more likely to be screened after adjusting for age, sex, and comorbidities. In our practice, cancer screening rates among chronic dialysis patients are lower than those previously reported for our general population (64% for breast cancer). However, a sizeable proportion of our ESRD population does receive cancer screening, especially those still seen in primary care.
