Foot and Ankle Care by Podiatrists and Amputations in Patients With Diabetes and Kidney Failure.

Importance: Patients with kidney failure have an increased risk of diabetes-related foot complications. The benefit of regular foot and ankle care in this at-risk population is unknown. Objective: To investigate foot and ankle care by podiatrists and the outcomes of diabetic foot ulcers (DFUs) in patients with kidney failure. Design, Setting, and Participants: This retrospective cohort study included Medicare beneficiaries with type 2 diabetes receiving dialysis who had a new DFU diagnosis. The analysis of the calendar year 2016 to 2019 data from the United States Renal Data System was performed on June 15, 2023, with subsequent updates on December 11, 2023. Exposures: Foot and ankle care by podiatrists during 3 months prior to DFU diagnosis. Main Outcomes and Measures: The outcomes were a composite of death and/or major amputation, as well as major amputation alone. Kaplan-Meier analysis was used to estimate 2 to 3 years of amputation-free survival. Foot and ankle care by podiatrists and the composite outcome was examined using inverse probability-weighted Cox regression, while competing risk regression models were used for the analysis of amputation alone. Results: Among the 14 935 adult patients with kidney failure and a new DFU (mean [SD] age, 59.3 [12.7] years; 35.4% aged ≥65 years; 8284 men [55.4%]; Asian, 2.7%; Black/African American, 35.0%; Hispanic, 17.7%; White, 58.5%), 18.4% (n = 2736) received care by podiatrists in the 3 months before index DFU diagnosis. These patients were older, more likely to be male, and have more comorbidities than those without prior podiatrist visits. Over a mean (SD) 13.5 (12.0)-month follow-up, 70% of those with podiatric care experienced death and/or major amputation, compared with 74% in the nonpodiatric group. Survival probabilities at 36 months were 26.3% vs 22.8% (P < .001, unadjusted Kaplan-Meier survival analysis). In multivariate regression analysis, foot and ankle care was associated with an 11% lower likelihood of death and/or amputation (hazard ratio [HR], 0.89 95% CI, 0.84-0.93) and a 9% lower likelihood of major amputation (above or below knee) (HR, 0.91; 95% CI, 0.84-0.99) than those who did not. Conclusions and Relevance: The findings of this study suggest that patients with kidney failure at risk for DFUs who receive foot and ankle care from podiatrists may be associated with a reduced likelihood of diabetes-related amputations.

Service Utilization Patterns and Direct Medical Costs of Hospitalization in Patients With Renal Failure Before and After Initiating Home Peritoneal Dialysis.

OBJECTIVES: This study aimed to determine the hospital service utilization patterns and direct healthcare hospital costs before and during peritoneal dialysis (PD) at home. METHODS: A retrospective cohort study of patients with kidney failure (KF) was conducted at a Mexican Social Security Institute hospital for the year 2014. Cost categories included inpatient emergency room stays, inpatient services at internal medicine or surgery, and hospital PD. The study groups were (1) patients with KF before initiating home PD, (2) patients with less than 1 year of home PD (incident), and (3) patients with more than 1 year of home PD (prevalent). Costs were actualized to international dollars (Int$) 2023. RESULTS: We found that 53% of patients with KF used home PD services, 42% had not received any type of PD, and 5% had hospital dialysis while waiting for home PD. The estimated costs adjusting for age and sex were Int$5339 (95% CI 4680-9746) for patients without home PD, Int$17 556 (95% CI 15 314-19 789) for incident patients, and Int$7872 (95% CI 5994-9749) for prevalent patients; with significantly different averages for the 3 groups (P < .001). CONCLUSIONS: Although the use of services and cost is highest at the time of initiating PD, over time, using home PD leads to a significant reduction in use of hospital services, which translates into institutional cost savings. Our findings, especially considering the high rates of KF in Mexico, suggest a pressing need for interventions that can reduce healthcare costs at the beginning of renal replacement therapy.

Multicentre external validation of the prognostic model kidney failure risk equation in patients with CKD stages 3 and 4 in Peru: a retrospective cohort study.

OBJECTIVES: To externally validate the four-variable kidney failure risk equation (KFRE) in the Peruvian population for predicting kidney failure at 2 and 5 years. DESIGN: A retrospective cohort study. SETTING: 17 primary care centres from the Health's Social Security of Peru. PARTICIPANTS: Patients older than 18 years, diagnosed with chronic kidney disease stage 3a-3b-4 and 3b-4, between January 2013 and December 2017. Patients were followed until they developed kidney failure, died, were lost, or ended the study (31 December 2019), whichever came first. PRIMARY AND SECONDARY OUTCOME MEASURES: Performance of the KFRE model was assessed based on discrimination and calibration measures considering the competing risk of death. RESULTS: We included 7519 patients in stages 3a-4 and 2798 patients in stages 3b-4. The estimated cumulative incidence of kidney failure, accounting for competing event of death, at 2 years and 5 years, was 1.52% and 3.37% in stages 3a-4 and 3.15% and 6.86% in stages 3b-4. KFRE discrimination at 2 and 5 years was high, with time-dependent area under the curve and C-index >0.8 for all populations. Regarding calibration in-the-large, the observed to expected ratio and the calibration intercept indicated that KFRE underestimates the overall risk at 2 years and overestimates it at 5 years in all populations. CONCLUSIONS: The four-variable KFRE models have good discrimination but poor calibration in the Peruvian population. The model underestimates the risk of kidney failure in the short term and overestimates it in the long term. Further research should focus on updating or recalibrating the KFRE model to better predict kidney failure in the Peruvian context before recommending its use in clinical practice.

Using Relative Survival to Estimate the Burden of Kidney Failure.

RATIONALE & OBJECTIVE: Estimates of mortality from kidney failure are misleading because the mortality from kidney failure is inseparable from the mortality attributed to comorbid conditions. We sought to develop an alternative method to reduce the bias in estimating mortality due to kidney failure using life table methods. STUDY DESIGN: Longitudinal cohort study. SETTING & PARTICIPANTS: Using data from the US Renal Data System and the Medicare 5% sample, we identified an incident cohort of patients, age 66+, who first had kidney failure in 2009 and a similar general population cohort without kidney failure. EXPOSURE: Kidney failure. OUTCOME: Death. ANALYTICAL APPROACH: We created comorbidity, age, sex, race, and year-specific life tables to estimate relative survival of patients with incident kidney failure and to attain an estimate of excess kidney failure-related deaths. Estimates were compared with those based on standard life tables (not adjusted for comorbidity). RESULTS: The analysis included 31,944 adults with kidney failure with a mean age of 77±7 years. The 5-year relative survival was 31% using standard life tables (adjusted for age, sex, race, and year) versus 36% using life tables also adjusted for comorbidities. Compared with other chronic diseases, patients with kidney failure have among the lowest relative survival. Patients with incident kidney failure ages 66-70 and 76-80 have a survival comparable to adults without kidney failure roughly 86-90 and 91-95 years old, respectively. LIMITATIONS: Relative survival estimates can be improved by narrowing the specificity of the covariates collected (eg, disease severity and ethnicity). CONCLUSIONS: Estimates of survival relative to a matched general population partition the mortality due to kidney failure from other causes of death. Results highlight the immense burden of kidney failure on mortality and the importance of disease prevention efforts among older adults. PLAIN-LANGUAGE SUMMARY: Estimates of death due to kidney failure can be misleading because death information from kidney failure is intertwined with death due to aging and other chronic diseases. Life tables are an old method, commonly used by actuaries and demographers to describe the life expectancy of a population. We developed life tables specific to a patient's age, sex, year, race, and comorbidity. Survival is derived from the life tables as the percentage of patients who are still alive in a specified period. By comparing survival of patients with kidney failure to the survival of people from the general population, we estimate that patients with kidney failure have one-third the chance of survival in 5 years compared with people with similar demographics and comorbidity but without kidney failure. The importance of this measure is that it provides a quantifiable estimate of the immense mortality burden of kidney failure.

Análisis geográfico de nefropatía diabética e insuficiencia renal en el primer nivel de atención, IMSS 2019 / Geographic analysis of diabetic nephropathy and renal insufficiency in the primary care, IMSS 2019

Introducción: en un contexto donde la prevalencia de diabetes mellitus e hipertensión arterial ha aumentado significativamente en años recientes, las enfermedades renales adquieren importancia por la potencial demanda de atención especializada y de recursos en salud que requieren. Objetivo: analizar la distribución geográfica de la nefropatía diabética (ND) y la insuficiencia renal (IR) con base en las consultas otorgadas en unidades de primer nivel del Instituto Mexicano del Seguro Social (IMSS) durante 2019, para identificar las unidades médicas con mayor carga de atención. Material y métodos: estudio ecológico-exploratorio en el que se estimaron indicadores por cada mil derechohabientes en relación a las consultas otorgadas por ND e IR según la ocasión de servicio, la unidad médica familiar (UMF) de primer nivel y la representación. Se utilizó estadística espacial para analizar dichos indicadores. Resultados: el 45% de las consultas otorgadas fue por ND y el 52.4% por IR. La mayor carga por ND se registró en la UMF No. 50 de Cd. Juárez (Chihuahua) y en la No. 49 Gabino Barreda (Veracruz Sur), con 1.7 consultas de primera vez y 148.3 subsecuentes por mil derechohabientes, respectivamente. Mientras que en la UMF No. 40 Manlio Fabio Altamirano y No. 25 Cotaxtla, en Veracruz Norte, la mayor carga fue por IR, con 4.9 consultas de primera vez y 134.2 subsecuentes por mil derechohabientes, respectivamente. Conclusiones: los resultados podrían contribuir al fortalecimiento de las unidades médicas que así lo requieran y en la distribución eficiente de los recursos disponibles para atender la demanda de servicios de salud de ND e IR en el IMSS

Background: In a context where the prevalence of Diabetes Mellitus and Hypertension has increased significantly in recent years, kidney diseases become important for the potential demand for specialized health care and resources required. Objective: To analyze the geographical distribution of Diabetic Nephropathy (DN) and Renal Insufficiency (RI) based on the medical consultations given in first-level units of IMSS during 2019, to identify the medical units with the highest burden of care. Material and methods: Ecological-exploratory study in which indicators were estimated for every thousand persons in relation to medical consultations given by ND and RI according to service time, first-level medical unit (UMF) and representation to analyze the magnitude and geographic distribution at the national level. Results: 45% of medical consultations were by ND and 52.4% by RI. The highest burden per DN was registered in UMF No. 50 Cd. Juarez (Chihuahua) and No. 49 Gabino Barreda (Veracruz Sur), with 1.7 first-time medical consultations and 148.3 subsequent medical consultations per 1,000 persons, respectively. While in UMF No. 40 Manlio Fabio Altamirano and No. 25 Cotaxtla, in Veracruz Norte, the highest burden was for RI, with 4.9 first-time medical consultations and 134.2 subsequent medical consultations per 1000 persons, respectively. Conclusions: The results could contribute to strengthening of medical units where it is necessary and the efficient allocation of resources available to meet the demand for health services of ND and RI in IMSS.

Medication-related adverse events in health care-what have we learned? A narrative overview of the current knowledge.

PURPOSE: Although medication-related adverse events (MRAEs) in health care are vastly studied, high heterogeneity in study results complicates the interpretations of the current situation. The main objective of this study was to form an up-to-date overview of the current knowledge of the prevalence, risk factors, and surveillance of MRAEs in health care. METHODS: Electronic databases (PubMed, MEDLINE, Web of Science, and Scopus) were searched with applicable search terms to collect information on medication-related adverse events. In order to obtain an up-to-date view of MRAEs, only studies published after 2000 were accepted. RESULTS: The prevalence rates of different MRAEs vary greatly between individual studies and meta-analyses. Study setting, patient population, and detection methods play an important role in determining detection rates, which should be regarded while interpreting the results. Medication-related adverse events are more common in elderly patients and patients with lowered liver or kidney function, polypharmacy, and a large number of additional comorbidities. However, the risk of MRAEs is also significantly increased by the use of high-risk medicines but also in certain care situations. Preventing MRAEs is important as it will decrease patient mortality and morbidity but also reduce costs and functional challenges related to them. CONCLUSIONS: Medication-related adverse events are highly common and have both immediate and long-term effects to patients and healthcare systems worldwide. Conclusive solutions for prevention of all medication-related harm are impossible to create. In the future, however, the development of efficient real-time detection methods can provide significant improvements for event prevention and forecasting.

Global burden of disease: acute-on-chronic liver failure, a systematic review and meta-analysis.

BACKGROUND AND AIMS: Acute-on-chronic liver failure (ACLF) is characterised by acute decompensation of cirrhosis associated with organ failures. We systematically evaluated the geographical variations of ACLF across the world in terms of prevalence, mortality, aetiology of chronic liver disease (CLD), triggers and organ failures. METHODS: We searched EMBASE and PubMed from 3/1/2013 to 7/3/2020 using the ACLF-EASL-CLIF (European Association for the Study of the Liver-Chronic Liver Failure) criteria. Two investigators independently conducted the abstract selection/abstraction of the aetiology of CLD, triggers, organ failures and prevalence/mortality by presence/grade of ACLF. We grouped countries into Europe, East/South Asia and North/South America. We calculated the pooled proportions, evaluated the methodological quality using the Newcastle-Ottawa Scale and statistical heterogeneity, and performed sensitivity analyses. RESULTS: We identified 2369 studies; 30 cohort studies met our inclusion criteria (43 206 patients with ACLF and 140 835 without ACLF). The global prevalence of ACLF among patients admitted with decompensated cirrhosis was 35% (95% CI 33% to 38%), highest in South Asia at 65%. The global 90-day mortality was 58% (95% CI 51% to 64%), highest in South America at 73%. Alcohol was the most frequently reported aetiology of underlying CLD (45%, 95% CI 41 to 50). Infection was the most frequent trigger (35%) and kidney dysfunction the most common organ failure (49%). Sensitivity analyses showed regional estimates grossly unchanged for high-quality studies. Type of design, country health index, underlying CLD and triggers explained the variation in estimates. CONCLUSIONS: The global prevalence and mortality of ACLF are high. Region-specific variations could be explained by the type of triggers/aetiology of CLD or grade. Health systems will need to tailor early recognition and treatment of ACLF based on region-specific data.

Medicaid Expansion and Incidence of Kidney Failure among Nonelderly Adults.

BACKGROUND: Low-income individuals without health insurance have limited access to health care. Medicaid expansions may reduce kidney failure incidence by improving access to chronic disease care. METHODS: Using a difference-in-differences analysis, we examined the association between Medicaid expansion status under the Affordable Care Act (ACA) and the kidney failure incidence rate among all nonelderly adults, aged 19-64 years, in the United States, from 2012 through 2018. We compared changes in kidney failure incidence in states that implemented Medicaid expansions with concurrent changes in nonexpansion states during pre-expansion, early postexpansion (years 2 and 3 postexpansion), and later postexpansion (years 4 and 5 postexpansion). RESULTS: The unadjusted kidney failure incidence rate increased in the early years of the study period in both expansion and nonexpansion states before stabilizing. After adjustment for population sociodemographic characteristics, Medicaid expansion status was associated with 2.20 fewer incident cases of kidney failure per million adults per quarter in the early postexpansion period (95% CI, -3.89 to -0.51) compared with nonexpansion status, a 3.07% relative reduction (95% CI, -5.43% to -0.72%). In the later postexpansion period, Medicaid expansion status was not associated with a statistically significant change in kidney failure incidence (-0.56 cases per million per quarter; 95% CI, -2.71 to 1.58) compared with nonexpansion status and the pre-expansion time period. CONCLUSIONS: The ACA Medicaid expansion was associated with an initial reduction in kidney failure incidence among the entire, nonelderly, adult population in the United States; but the changes did not persist in the later postexpansion period. Further study is needed to determine the long-term association between Medicaid expansion and changes in kidney failure incidence.

HCV Seroprevalence among HIV Patients and Associated Comorbidities at One Primary Health Facility in Rwanda.

Hepatitis C virus (HCV) and HIV have emerged as major viral infections within the past two decades, and their coinfection poses a big challenge with a significant impact in terms of morbidity and mortality associated with liver disease and renal failure. The current study aimed at assessing the prevalence of HCV infection and associated comorbidities among HIV patients at one primary health facility in Rwanda. In total, 417 HIV-positive patients were recruited and included in the study from January 1, 2019 up to June 30, 2019. All participants were screened for HCV infection by using the SD Bioline HCV antibody rapid test. In addition, underlying medical conditions were also recorded as comorbidities. Among 417 participants, 52 exhibited HCV-positive results (12.5%). The group of 41- to 50- and 51- to 60-year-olds had higher prevalence of HIV/HCV coinfection than other age-groups with 3.6% and 4.6%, respectively. Furthermore, five underlying medical conditions were found as comorbidities among the study participants. Those with HIV/HCV coinfection showed higher comorbidities than those with mono-infection including liver toxicity, P value 0.005; tuberculosis, P value 0.005; renal failure, P value 0.003; hypertension, P value 0.001; and diabetes mellitus, P value 0.001. The relative risk ratio of having comorbidities in those groups was 4.09. To conclude, the prevalence of HCV/HIV coinfection is high, and there was a statistical significant association of having comorbidities in HIV/HCV-coinfected group compared with the group of HIV mono-infection, which suggests more intervention in this vulnerable group of patients.

Application of physiologically based pharmacokinetic modeling to predict the pharmacokinetics of telavancin in obesity with renal impairment.

PURPOSE: U.S. Food and Drug Administration (FDA) recommended telavancin dosing is based on total body weight (TBW) but lacks adjusted regimens for obese subjects with varying renal function. Our aim was to develop a physiologically based pharmacokinetic (PBPK) model of telavancin to design optimized dosing regimens for obese patients with hospital-acquired pneumonia (HAP) and varying renal function. METHODS: The PBPK model was verified using clinical pharmacokinetic (PK) data of telavancin in healthy populations with varying renal function and obese populations with normal renal function. Then, the PBPK model was applied to predict the PK in obese HAP patients with renal impairment (RI). RESULTS: The fold error values of PK parameters (AUC, Cmax, Tmax) were all within 1.5. The telavancin AUC0-inf was predicted to increase 1.07-fold in mild RI, 1.23-fold in moderate RI, 1.41-fold in severe RI, and 1.57-fold in end-stage renal disease (ESRD), compared with that in obese HAP with normal renal function. The PBPK model combined with Monte Carlo simulations (MCS) suggested that dose adjustment based on a 750-mg-fixed dose could achieve effectiveness with reduced risk of toxicity, compared with current TBW-based dosing recommendations. CONCLUSION: The PBPK simulation proposed that using TBW-based regimen in obesity with RI should be avoided. Dose recommendations in obesity from the PBPK model are 750 mg daily for normal renal function and mild RI, 610 mg daily for moderate RI, 530 mg daily for severe RI, and 480 mg daily for ESRD.

Sex Disparities in the Choice of Cardiac Resynchronization Therapy Device: An Analysis of Trends, Predictors, and Outcomes.

BACKGROUND: There is limited evidence on the influence of sex on the decision to implant a cardiac resynchronization therapy device with pacemaker (CRT-P) or defibrillator (CRT-D) and the existence of sex-dependent differences in complications that may affect this decision. METHODS: All patients undergoing de novo CRT implantation (2004-2014) in the United States National Inpatient Sample were included and stratified by device type (CRT-P and CRT-D). Multivariable logistic regression models were conducted to assess the association of female sex with receipt of CRT-D and periprocedural complications. RESULTS: Out of 400,823 weighted CRT procedural records, the overall percentages of women undergoing CRT-P and CRT-D implantations were 41.5% and 27.8%, respectively, and these percentages increased compared with men over the study period. Women were less likely to receive CRT-D (odds ratio 0.66, 95% confidence interval 0.64-0.67), and this trend remained stable throughout the study period (P = 0.06). Furthermore, compared with men, women were associated with increased odds of procedure-related complications (bleeding, thoracic, and cardiac) in the CRT-D group but not in the CRT-P group. Factors such as atrial fibrillation, malignancies, renal failure, advanced age (> 60 years), and admission to nonurban/small hospitals favoured the receipt of CRT-P over CRT-D, whereas history of ischemic heart disease, cardiac arrest ,or ventricular arrhythmias favoured the receipt of CRT-D over CRT-P. CONCLUSIONS: Women were associated with persistently reduced odds of receipt of CRT-D compared with men over an 11-year period. This study identifies important factors that predict the choice of CRT device offered to patients in the United States.

Multiple Myeloma in Hispanics: Incidence, Characteristics, Survival, Results of Discovery, and Validation Using Real-World and Connect MM Registry Data.

BACKGROUND: Multiple myeloma (MM) in Hispanics has never been studied. We therefore sought to determine the clinical characteristics and overall survival in MM of Hispanics compared to non-Hispanic whites (NHW) and non-Hispanic blacks (NHB). PATIENTS AND METHODS: A single-center analysis of 939 patients diagnosed with MM from 2000 to 2017 with a large representation of NHB (n = 489), Hispanics (n = 281), and NHW (n = 169) was conducted to evaluate outcomes and disease characteristics. We used the Connect MM Registry, a large US multicenter prospective observational study with newly diagnosed MM patients, as a validation cohort. RESULTS: Hispanics had a higher incidence of MM compared to NHW. The median age at presentation was 5 years younger (median, 65 years) in Hispanics compared to NHW (median, 70 years), and patients were more likely to present with renal dysfunction (estimated glomerular filtration rate < 30 mL/min). Hispanics had a higher proportion of Revised International Staging System (R-ISS) stage I disease compared to NHW and NHB (P = .03), while there was no difference in cytogenetics between Hispanics and NHB/NHW. In the multivariate analysis, only high-risk disease and response to first-line therapy significantly affected survival. CONCLUSION: In this first and largest analysis of MM in Hispanics, we found that Hispanics present at a younger age, have a higher incidence of renal dysfunction, and have low R-ISS stage disease at presentation. With equal access to therapy, Hispanics have survival similar to NHW/NHB.

The current and future landscape of dialysis.

The development of dialysis by early pioneers such as Willem Kolff and Belding Scribner set in motion several dramatic changes in the epidemiology, economics and ethical frameworks for the treatment of kidney failure. However, despite a rapid expansion in the provision of dialysis - particularly haemodialysis and most notably in high-income countries (HICs) - the rate of true patient-centred innovation has slowed. Current trends are particularly concerning from a global perspective: current costs are not sustainable, even for HICs, and globally, most people who develop kidney failure forego treatment, resulting in millions of deaths every year. Thus, there is an urgent need to develop new approaches and dialysis modalities that are cost-effective, accessible and offer improved patient outcomes. Nephrology researchers are increasingly engaging with patients to determine their priorities for meaningful outcomes that should be used to measure progress. The overarching message from this engagement is that while patients value longevity, reducing symptom burden and achieving maximal functional and social rehabilitation are prioritized more highly. In response, patients, payors, regulators and health-care systems are increasingly demanding improved value, which can only come about through true patient-centred innovation that supports high-quality, high-value care. Substantial efforts are now underway to support requisite transformative changes. These efforts need to be catalysed, promoted and fostered through international collaboration and harmonization.

Ensuring Sustainability of Continuous Kidney Replacement Therapy in the Face of Extraordinary Demand: Lessons From the COVID-19 Pandemic.

With the exponential surge in patients with coronavirus disease 2019 (COVID-19) worldwide, the resources needed to provide continuous kidney replacement therapy (CKRT) for patients with acute kidney injury or kidney failure may be threatened. This article summarizes subsisting strategies that can be implemented immediately. Pre-emptive weekly multicenter projections of CKRT demand based on evolving COVID-19 epidemiology and routine workload should be made. Corresponding consumables should be quantified and acquired, with diversification of sources from multiple vendors. Supply procurement should be stepped up accordingly so that a several-week stock is amassed, with administrative oversight to prevent disproportionate hoarding by institutions. Consumption of CKRT resources can be made more efficient by optimizing circuit anticoagulation to preserve filters, extending use of each vascular access, lowering blood flows to reduce citrate consumption, moderating the CKRT intensity to conserve fluids, or running accelerated KRT at higher clearance to treat more patients per machine. If logistically feasible, earlier transition to intermittent hemodialysis with online-generated dialysate, or urgent peritoneal dialysis in selected patients, may help reduce CKRT dependency. These measures, coupled to multicenter collaboration and a corresponding increase in trained medical and nursing staffing levels, may avoid downstream rationing of care and save lives during the peak of the pandemic.

Regular Bleeding Risk Assessment Associated with Reduction in Bleeding Outcomes: The mAFA-II Randomized Trial.

BACKGROUND: The mobile atrial fibrillation application (mAFA-II) randomized trial reported that a holistic management strategy supported by mobile health reduced atrial fibrillation-related adverse outcomes. The present study aimed to assess whether regular reassessment of bleeding risk using the Hypertension, Abnormal renal and liver function, Stroke, Bleeding, Labile international normalized ratio, Elderly, Drugs or alcohol (HAS-BLED) score would improve bleeding outcomes and oral anticoagulant (OAC) uptake. METHODS: Bleeding risk (HAS-BLED score) was monitored prospectively using mAFA, and calculated as 30 days, days 31-60, days 61-180, and days 181-365. Clinical events and OAC changes in relation to the dynamic monitoring were analyzed. RESULTS: We studied 1793 patients with atrial fibrillation (mean, standard deviation, age 64 years, 24 years, 32.5% female). Comparing baseline and 12 months, the proportion of atrial fibrillation patients with HAS-BLED ≥3 decreased (11.8% vs 8.5%, P = .008), with changes in use of concomitant nonsteroidal antiinflammatory drugs/antiplatelets, renal dysfunction, and labile international normalized ratio contributing to the decreased proportions of patients with HAS-BLED ≥3 (P < .05). Among 1077 (60%) patients who had 4 bleeding risk assessments, incident bleeding events decreased significantly from days 1-30 to days 181-365 (1.2% to 0.2%, respectively, P < .001). Total OAC usage increased from 63.4% to 70.2% (Ptrend < .001). Compared with atrial fibrillation patients receiving usual care (n = 1136), bleeding events were significantly lower in atrial fibrillation patients with dynamic monitoring of their bleeding risk (mAFA vs usual care, 2.1%, 4.3%, P = .004). OAC use decreased significantly by 25% among AF patients receiving usual care, when comparing baseline to 12 months (P < .001). CONCLUSION: Dynamic risk monitoring using the HAS-BLED score, together with holistic App-based management using mAFA-II reduced bleeding events, addressed modifiable bleeding risks, and increased uptake of OACs.

Use of pre-ART laboratory screening to identify renal, hepatic and haematological abnormalities in Côte d'Ivoire.

BACKGROUND: High demand for HIV-services and extensive clinical guidelines force health systems in low-resource settings to dedicate resources to service delivery at the expense of other priorities. Simplifying services may reduce the burden on health systems and pre-antiretroviral therapy (ART) laboratory screening is among the services under consideration for simplification. METHODS: We assessed the frequencies of conditions linked to ART toxicities among 34,994 adult, ART-naïve patients with specimens referred to the RETRO-CI laboratory in Abidjan, Côte d'Ivoire between 1998 and 2017. Screening included tests for serum creatinine, alanine aminotransferase (ALT) and haemoglobin (Hb) to identify renal dysfunction (estimated glomerular filtration rate < 50 mL/min), hepatic abnormalities (ALT > 5× upper limit of normal) and severe anaemia (Hb < 6.5 g/dL), respectively. We considered screening results across four eras and identified factors associated with the conditions in question. RESULTS: The prevalence of renal dysfunction, hepatic abnormalities and severe anaemia were largely unchanged over time and just 8.4% of patients had any of the three conditions. Key factors associated with renal dysfunction and severe anaemia were age > 50 years (adjusted odds ratio (aOR): 2.53; 95% confidence interval (CI): 2.19-2.92; P < 0.001) and CD4 < 100 cells/µl (aOR: 2.57; 95% CI: 2.30-2.88; P < 0.001). CONCLUSION: The relative infrequency of conditions linked to toxicity in Côte d'Ivoire supports the notion that simplification of pre-ART laboratory screening may be undertaken with limited negative impact on identification of adverse events. Targeted screening may be a feasible strategy to balance detection of conditions associated with ART toxicities with simplification of services.

CONTEXTE: La forte demande de services VIH et les directives cliniques détaillées obligent les systèmes de santé des pays à faibles ressources à consacrer des ressources à la prestation de services au détriment d'autres priorités. La simplification des services peut réduire la charge pesant sur les systèmes de santé et les analyses de laboratoire avant la thérapie antirétrovirale (ART) fait partie des services envisagés pour la simplification. MÉTHODES: Nous avons évalué la fréquence des conditions liées aux toxicités dues à l'ART chez 34.994 patients adultes naïfs pour l'ART avec des échantillons référés au laboratoire RETRO-CI à Abidjan, en Côte d'Ivoire entre 1998 et 2017. Les analyses comprenaient les tests de créatinine sérique, d'alanine aminotransférase (ALT) et d'hémoglobine (Hb) pour identifier respectivement la dysfonction rénale (débit de filtration glomérulaire estimé <50 mL/min), les anomalies hépatiques (ALT >5x la limite supérieure normale) et l'anémie sévère (Hb <6,5 g/dL). Nous avons examiné les résultats des analyses sur quatre époques et identifié les conditions associées aux conditions en question. RÉSULTATS: La prévalence de la dysfonction rénale, des anomalies hépatiques et de l'anémie sévère est restée largement inchangée au fil du temps et seulement 8,4% des patients présentaient l'une des trois conditions. Les facteurs clés associés à la dysfonction rénale et à l'anémie sévère étaient l'âge >50 ans (odds ratio ajusté (aOR): 2,53; intervalle de confiance (IC) à 95%: 2,19 à 2,92; p <0,001) et les CD4 <100 cellules/µl (aOR: 2,57; IC95%: 2,30 à 2,88; P < 0,001). CONCLUSION: La relativement faible fréquence des conditions liées à la toxicité en Côte d'Ivoire soutient la notion selon laquelle une simplification des analyses de laboratoire pré-ART peut être entreprise avec un impact négatif limité sur l'identification des événements adverses. Le ciblage des analyses peut être une stratégie réalisable pour aligner la détection des conditions associées aux toxicités ART à la simplification des services.

Nationwide Analysis of Inpatient Laparoscopic Versus Open Inguinal Hernia Repair.

Background: Inguinal hernia repair is one of the more common procedures performed in the United States. The optimal surgical approach, however, remains controversial. We aimed to compare the postoperative outcomes and costs between laparoscopic and open inpatient inguinal hernia repairs in a national cohort. Materials and Methods: We performed a retrospective analysis of the National Inpatient Sample during the period 2009-2015. Adult patients (≥18 years old) undergoing laparoscopic and open inguinal hernia repair were included. Multivariable logistic, generalized logistic, and linear regression were used to assess the effect of the laparoscopic approach on postoperative complications, mortality, length of stay, and hospital charges. Results: A total of 41,937 patients undergoing open inguinal hernia repair (N = 36,575) and laparoscopic inguinal hernia repair (N = 5282) were included. Patients undergoing laparoscopic inguinal hernia repair were less likely to have postoperative wound complications (odds ratio [OR]: 0.64, 95% confidence interval [CI]: 0.41-0.98), infection (OR: 0.34, 95% CI: 0.27-0.42), bleeding (OR: 0.72, 95% CI: 0.63-0.82), cardiac failure (OR: 0.72, 95% CI: 0.64-0.82), renal failure (OR: 0.54, 95% CI: 0.47-0.62), respiratory failure (OR: 0.70, 95% CI: 0.58-0.85), and inpatient mortality (OR: 0.27, 95% CI: 0.17-0.40). On average, the laparoscopic approach reduced length of stay by 1.28 days (95% CI: -1.58 to -1.18), and decreased hospital costs by $2400 (95% CI: -$4700 to -$700). Conclusion: Laparoscopic hernia repair is associated with significantly lower rates of postoperative morbidity and mortality, shorter length of hospital stays, and lower hospital costs for inpatient repairs. The laparoscopic approach should be encouraged for the management of appropriate patients with inpatient inguinal hernias.
