Dialysis Initiation in Patients With Chronic Coronary Disease and Advanced Chronic Kidney Disease in ISCHEMIA-CKD

BACKGROUND: In participants with concomitant chronic coronary disease and advanced chronic kidney disease (CKD), the effect of treatment strategies on the timing of dialysis initiation is not well characterized. METHODS AND RESULTS: In ISCHEMIA‐CKD (International Study of Comparative Health Effectiveness With Medical and Invasive Approaches–Chronic Kidney Disease), 777 participants with advanced CKD and moderate or severe ischemia were randomized to either an initial invasive or conservative management strategy. Herein, we compare the proportion of randomized participants with non–dialysis‐requiring CKD at baseline (n=362) who initiated dialysis and compare the time to dialysis initiation between invasive versus conservative management arms. Using multivariable Cox regression analysis, we also sought to identify the effect of invasive versus conservative chronic coronary disease management strategies on dialysis initiation. At a median follow‐up of 23 months (25th–75th interquartile range, 14–32 months), dialysis was initiated in 18.9% of participants (36/190) in the invasive strategy and 16.9% of participants (29/172) in the conservative strategy (P=0.22). The median time to dialysis initiation was 6.0 months (interquartile range, 3.0–16.0 months) in the invasive group and 18.2 months (interquartile range, 12.2–25.0 months) in the conservative group (P=0.004), with no difference in procedural acute kidney injury rates between the groups (7.8% versus 5.4%; P=0.26). Baseline clinical factors associated with earlier dialysis initiation were lower baseline estimated glomerular filtration rate (hazard ratio [HR] associated with 5‐unit decrease, 2.08 [95% CI, 1.72–2.56]; P<0.001), diabetes (HR, 2.30 [95% CI, 1.28–4.13]; P=0.005), hypertension (HR, 7.97 [95% CI, 1.09–58.21]; P=0.041), and Hispanic ethnicity (HR, 2.34 [95% CI, 1.22–4.47]; P=0.010). CONCLUSIONS: In participants with non–dialysis‐requiring CKD in ISCHEMIA‐CKD, randomization to an invasive chronic coronary disease management strategy (relative to a conservative chronic coronary disease management strategy) is associated with an accelerated time to initiation of maintenance dialysis for kidney failure

Acute kidney disease and renal recovery : consensus report of the Acute Disease Quality Initiative (ADQI) 16 Workgroup

Consensus definitions have been reached for both acute kidney injury (AKI) and chronic kidney disease (CKD) and these definitions are now routinely used in research and clinical practice. The KDIGO guideline defines AKI as an abrupt decrease in kidney function occurring over 7 days or less, whereas CKD is defined by the persistence of kidney disease for a period of > 90 days. AKI and CKD are increasingly recognized as related entities and in some instances probably represent a continuum of the disease process. For patients in whom pathophysiologic processes are ongoing, the term acute kidney disease (AKD) has been proposed to define the course of disease after AKI; however, definitions of AKD and strategies for the management of patients with AKD are not currently available. In this consensus statement, the Acute Disease Quality Initiative (ADQI) proposes definitions, staging criteria for AKD, and strategies for the management of affected patients. We also make recommendations for areas of future research, which aim to improve understanding of the underlying processes and improve outcomes for patients with AKD

The Relationship between Distance to Care and Readmission for Reintervention Following Lower Extremity Arterial Bypass: An Exploratory Study

Context: Health care utilization and outcomes have been linked to multiple factors both clinical and non-clinical, including distance to care. Purpose: The purpose of this study was to test the association between distance to care and readmission for reintervention in the year following lower extremity arterial bypass in the Veterans Health Administration (VA). Methods: VA databases were used in this study of patients who underwent lower extremity arterial bypass from 2003 to 2006. Health care utilization was identified over the follow-up year. Readmission was regressed on distance to care using multivariate logistic regression models. Results: Out of 5,555 patients discharged following lower extremity bypass surgery, 23.3% were readmitted for reintervention within one year of surgery. Patients were almost exclusively male (99.1%), White (76.8%), with a mean age of 65.2 ± 9.8 years. Approximately 18.6% were Black and 4.6% were combined in a non-Black/non-White grouping. The majority, 62%, lived within 50 miles of the surgical center. Distance to care was not found to be significantly associated with readmission for reintervention after controlling for demographic factors, region, severity of illness, comorbidities, and outpatient vascular use. Significant factors for readmission in the fully adjusted logistic regression model included increasing age (OR=.99, p = .003), Black race (OR=1.2, p=.03) Midwest region (OR=.8, p =.01), intermittent claudication (OR = .8, p=.002), critical limb ischemia (OR =1.4, p \u3c.0001), diabetes (OR = 1.3, p\u3c.0001) and low outpatient vascular use (OR = .7, p \u3c.0001). Conclusion: As patients\u27 distance to care increased, they were not more likely to be readmitted for secondary procedures. Quality initiatives to improve access could be in part responsible; however, the effect of private sector utilization might also have affected the results. Recommendations for future research include expanding the study to obtain additional comorbidities and a prospective study designed to include clinical factors (medications, vascular testing, and additional comorbidities), health care utilization, and quality of life over the follow-up year

The cognitive-phenomenological assessment of delusions and hallucinations at the early intervention in psychosis service stage: The results of a quality improvement project

Aim Clinical assessments are vital for gaining an understanding of a patients' presenting problem. A priority for Early Intervention in Psychosis Service staff is understanding and supporting their patients' experiences of hallucinations and/or delusions. We aimed to identify what cognitive–phenomenology dimensions of hallucinations and delusions EIPS staff were assessing with their patients. Methods We developed a brief checklist of cognitive–phenomenological dimensions of hallucinations and delusions called the Lived Experience Symptom Survey (LESS) based on relevant literature. As part of a Quality Improvement Project, we reviewed the health records of a sub-sample of EIPS patients using the LESS identifying whether each dimension was present or absent. Results We found that all patients had been asked about the content of their hallucinations and/or delusions, and the majority had been asked about the valence of this content. Despite patients having experienced psychosis for almost 2 years on average, less than half of patients were asked about the potential or actual harm associated with these symptoms. All other cognitive–phenomenological dimensions were assessed inconsistently. Conclusions The assessment of hallucination and delusions in our EIPS was inconsistent and incomprehensive. These findings require replication in other EIPS' but may point to a need for guidelines and training around how to conduct a thorough assessment of hallucinations and delusions for current and future EIPS staff. Improved assessment of these symptoms will aid the development of risk assessments and treatment plans

Factors associated with HIV seroconversion in gay men in England at the start of the 21st century

Objectives: To detect and quantify current risk factors for HIV seroconversion among gay men seeking repeat tests at sexual health clinics.Design: Unmatched case control study conducted in London, Brighton and Manchester, UK.Methods: 75 cases (recent HIV positive test following a negative test within the past 2 years) and 157 controls (recent HIV negative test following a previous negative test within the past 2 years) completed a computer assisted self interview focused on sexual behaviour and lifestyle between HIV tests.Results: Cases and controls were similar in sociodemographics, years since commencing sex with men, lifetime number of HIV tests, reasons for seeking their previous HIV tests and the interval between last HIV tests (mean=10.5 months). Risk factors between tests included unprotected receptive anal intercourse (URAI) with partners not believed to be HIV negative (adjusted odds ratio (AOR) and 95% confidence interval 4.1, 1.8 to 9.3), where increased risk was associated with concomitant use of nitrite inhalants, receiving ejaculate and increasing numbers of partners. Independent risk was also detected for unprotected insertive anal intercourse (UIAI) with more than one man (AOR 2.7, 1.3 to 5.5) and use of nitrite inhalants (AOR 2.4, 1.1 to 5.2).Conclusions: HIV serodiscordant unprotected anal intercourse remains the primary context for HIV transmission among gay men, with increased risk associated with being the receptive partner, receiving ejaculate and use of nitrite inhalants. Although the HIV transmission risk of URAI is widely acknowledged, this study highlights the risk of UIAI and that nitrite inhalants may be an important facilitator of transmission when HIV exposure occurs
