Ontology highlight
ABSTRACT: Objectives
To determine the prevalence, determinants, and potential clinical relevance of adherence with the Dutch dosing guideline in patients with impaired renal function at hospital discharge.Design
Retrospective cohort study between January 2007 and July 2011.Setting
Academic teaching hospital in the Netherlands.Subjects
Patients with an estimated glomerular filtration rate (eGFR) between 10-50 ml/min/1.73 m(2) at discharge and prescribed one or more medicines of which the dose is renal function dependent.Main outcome measures
The prevalence of adherence with the Dutch renal dosing guideline was investigated, and the influence of possible determinants, such as reporting the eGFR and severity of renal impairment (severe: eGFR<30 and moderate: eGFR 30-50 ml/min/1.73 m(2)). Furthermore, the potential clinical relevance of non-adherence was assessed.Results
1327 patients were included, mean age 67 years, mean eGFR 38 ml/min/1.73 m(2). Adherence with the guideline was present in 53.9% (n=715) of patients. Reporting the eGFR, which was incorporated since April 2009, resulted in more adherence with the guideline: 50.7% vs. 57.0%, RR 1.12 (95% CI 1.02-1.25). Adherence was less in patients with severe renal impairment (46.0%), compared to patients with moderate renal impairment (58.1%, RR 0.79; 95% CI 0.70-0.89). 71.4% of the cases of non-adherence had the potential to cause moderate to severe harm.Conclusion
Required dosage adjustments in case of impaired renal function are often not performed at hospital discharge, which may cause harm to the majority of patients. Reporting the eGFR can be a small and simple first step to improve adherence with dosing guidelines.

Project description:In patients with kidney impairment, warfarin, a drug metabolized primarily by the cytochrome P-450 system, is initiated at similar doses and managed similarly as in the general medical population. Unfortunately, few data exist to guide dose adjustment in patients with decreased kidney function. Here, we determine the degree of warfarin dose reduction associated with kidney impairment and make recommendations for warfarin dosing.Cross-sectional analysis.Long-term warfarin users followed up at anticoagulation clinics (n = 980); 708 participants from the University of Alabama (UAB) and 272 participants from the University of Chicago (UIC).No/mild (estimated glomerular filtration rate [eGFR] ? 60 mL/min/1.73 m(2)), moderate (eGFR, 30-59 mL/min/1.73 m(2)), and severe (eGFR < 30 mL/min/1.73 m(2)) kidney impairment; CYP2C9 and VKORC1 genotype; age; race; sex; body mass; sociodemographic factors; smoking status; alcohol; vitamin K intake; comorbid conditions (eg, congestive heart failure); and drug interactions (eg, amiodarone and statins).Warfarin dose (milligrams per day) was evaluated using linear regression after adjustment for clinical, demographic, and genetic factors.Prevalences of moderate (31.8% and 27.6%) and severe kidney impairment (8.9% and 6.6%) were similar in the UAB and UIC cohorts. Warfarin dose requirements were significantly lower in patients with moderate and severe kidney impairment compared with those with no/mild kidney impairment in the UAB (P < 0.001) and UIC (P < 0.001) cohorts. Compared with patients with no/mild kidney impairment, patients with moderate kidney impairment required 9.5% lower doses (P < 0.001) and patients with severe kidney impairment required 19% lower doses (P < 0.001).No measurement of warfarin, serum albumin, vitamin K, and coagulation factors; no evaluation of other markers (eg, cystatin).Moderate and severe kidney impairment were associated with a reduction in warfarin dose requirements.

Project description:BACKGROUND:Evidence from several studies show poor guideline adherence to COPD treatment, but no such study has been undertaken in Norway. The objectives of this study, was to estimate and compare the guideline adherence to COPD treatment in general population-based and hospital-recruited COPD patients, and find possible predictors of guideline adherence. METHODS:From the prospective, observational EconCOPD-study, we analysed guideline adherence for 90 population-based COPD cases compared to 245 hospital-recruited COPD patients. Overall guideline adherence was defined as correct pharmacological treatment, and influenza vaccination the preceding year, and having received smoking cessation advice. Multivariate logistic regression analysis was performed with the dichotomous outcome overall guideline adherence adjusting for relevant variables. RESULTS:The overall guideline adherence for population-based COPD cases was 6.7%, significantly lower than the 29.8% overall guideline-adherence amongst hospital-recruited COPD patients. Adherence to pharmacological treatment guidelines was 10.0 and 35.5%, for the two recruitment sources, respectively. GOLD-stage 3 to 4 was associated with significantly better guideline adherence compared to GOLD-stage 2 (OR (95% CI) 18.9 (8.37,42.7)). The unadjusted difference between the two recruitment sources was completely explained by degree of airflow obstruction. CONCLUSION:Overall guideline adherence was very low for both recruitment sources. We call for increased attention from authorities and healthcare personnel to improve the quality of care given to this patient group.

Project description:Adherence to hypertension guidelines in the outpatient setting is low.To evaluate adherence to JNC VII guidelines in nursing home patients.Data were obtained from the 2004 National Nursing Home Survey (NNHS), a nationally representative sample of US nursing homes. Patients with hypertension were identified using ICD-9 codes. Adherence to JNC VII guidelines was defined as the use of a thiazide diuretic in patients without a compelling indication for a different class of antihypertensive medication, such as diabetes, chronic kidney disease, coronary artery disease, congestive heart failure, or a history of stroke.There were 13,507 patients in the 2004 NNHS survey, of whom 7,129 had hypertension.Of these 7,129 hypertensive patients, only 12.6% were on a thiazide. Out of the 7,129 hypertensive patients, 3,113 did not have diabetes, chronic kidney disease, coronary artery disease, congestive heart failure, or a history of stroke. Of these 3,113 patients, only 13.9% were on a thiazide. After excluding patients with a potential contraindication to a diuretic, such as hospice care or incontinence, only 18% were prescribed a thiazide. Of the 3,113 patients, 1,148 were on a single class of antihypertensive and more were prescribed a beta blocker, ACE inhibitor, calcium channel blocker, loop diuretic, and ARB than a thiazide diuretic.Adherence to hypertension guidelines among nursing home patients is low. The appropriate use of thiazide diuretics could reduce costs and improve blood pressure control and patient outcomes.

Project description:Background: Procalcitonin (PCT) is a biomarker that can help identify bacterial infections but can be difficult to interpret in the presence of renal dysfunction, which can elevate PCT even in the absence of infection. Objective: To determine the optimal PCT threshold to identify infection in patients with renal dysfunction and pneumonia or sepsis. Methods: A retrospective analysis was performed for inpatients with creatinine clearance of ≤60 mL/min and PCT level from 2018 to 2019. A pharmacist blinded to study outcomes classified patients as infected or noninfected based on predetermined criteria. Receiver operating characteristic curve analysis was performed to establish the optimal PCT threshold overall, as well as in subgroups of patients with chronic kidney disease (CKD), acute kidney injury (AKI), and end-stage renal disease (ESRD). Institutional review board approval was obtained. Results: A total of 198 patients were included in the study (99 infected, 99 noninfected). The optimal threshold in the AKI, CKD, and ESRD subgroups was determined to be 1.5 ng/mL, 0.1 ng/mL, and 1.75 ng/mL, respectively. Conclusion: The results of this study show that PCT thresholds were specific to type of renal dysfunction. These results differ from the traditionally accepted PCT threshold of 0.5 ng/mL for sepsis and 0.25 mg/mL for pneumonia. Future studies should confirm the appropriate PCT threshold in ESRD and CKD patient populations.

Project description:This article is the work product of the Continuous Glucose Monitor and Automated Insulin Dosing Systems in the Hospital Consensus Guideline Panel, which was organized by Diabetes Technology Society and met virtually on April 23, 2020. The guideline panel consisted of 24 international experts in the use of continuous glucose monitors (CGMs) and automated insulin dosing (AID) systems representing adult endocrinology, pediatric endocrinology, obstetrics and gynecology, advanced practice nursing, diabetes care and education, clinical chemistry, bioengineering, and product liability law. The panelists reviewed the medical literature pertaining to five topics: (1) continuation of home CGMs after hospitalization, (2) initiation of CGMs in the hospital, (3) continuation of AID systems in the hospital, (4) logistics and hands-on care of hospitalized patients using CGMs and AID systems, and (5) data management of CGMs and AID systems in the hospital. The panelists then developed three types of recommendations for each topic, including clinical practice (to use the technology optimally), research (to improve the safety and effectiveness of the technology), and hospital policies (to build an environment for facilitating use of these devices) for each of the five topics. The panelists voted on 78 proposed recommendations. Based on the panel vote, 77 recommendations were classified as either strong or mild. One recommendation failed to reach consensus. Additional research is needed on CGMs and AID systems in the hospital setting regarding device accuracy, practices for deployment, data management, and achievable outcomes. This guideline is intended to support these technologies for the management of hospitalized patients with diabetes.

Project description:Adherence to pediatric traumatic brain injury guidelines has been associated with improved survival and better functional outcome. However, the relationship between guideline adherence and hospitalization costs has not been examined. To evaluate the relationship between adherence to pediatric severe traumatic brain injury guidelines, measured by acute care clinical indicators, and the total costs of hospitalization associated with severe traumatic brain injury.Retrospective cohort study.Five regional pediatric trauma centers affiliated with academic medical centers.Demographic, injury, treatment, and charge data were included for pediatric patients (17 yr) with severe traumatic brain injury.Percent adherence to clinical indicators was determined for each patient. Cost-to-charge ratios were used to estimate ICU and total hospital costs for each patient. Generalized linear models evaluated the association between healthcare costs and adherence rate.Cost data for 235 patients were examined. Estimated mean adjusted hospital costs were $103,485 (95% CI, 98,553-108,416); adjusted ICU costs were $82,071 (95% CI, 78,559-85,582). No association was found between adherence to guidelines and total hospital or ICU costs, after adjusting for patient and injury characteristics. Adjusted regression model results provided cost ratio equal to 1.01 for hospital and ICU costs (95% CI, 0.99-1.03 and 0.99-1.02, respectively).Adherence to severe pediatric traumatic brain injury guidelines at these five leading pediatric trauma centers was not associated with increased hospitalization and ICU costs. Therefore, cost should not be a factor as institutions and providers strive to provide evidence-based guideline driven care of children with severe traumatic brain injury.

Project description:BackgroundChronic kidney disease (CKD) is increasingly common in hospitalized patients and is associated with increased risk for in-hospital morbidity and mortality. However, data regarding the prevalence of CKD in the African hospitalized patient population are limited. We therefore examined the prevalence and associated factors of impaired renal function and albuminuria among adult patients admitted to the internal medicine wards of a hospital in Northeast Ethiopia.MethodsA cross-sectional study was conducted from January 1 to April 30, 2020 at the inpatient settings of Dessie referral hospital. Data on demographics and medical history were obtained, and serum creatinine and albuminuria were analyzed. Estimated glomerular filtration rate (eGFR) was calculated using the Modification of Diet in Renal Disease (MDRD) equation. CKD was defined as impaired eGFR (<60 ml/min/1.73m2) and/or albuminuria. Univariate and multivariable analysis were conducted to determine factors associated with impaired eGFR and albuminuria.ResultsA total of 369 patients were included in this study. The prevalence of impaired eGFR was 19.0% (95%CI: 15.2%-23.2%) and albuminuria was 30.9% (95%CI: 26.3%-35.7%). Overall, 33.9% (95%CI: 29.2%-38.9%) of the patients had some degree of CKD, but only 21.6% (95%CI: 15.1%-29.4%) were aware of their renal disease. In multivariable analysis, older age, a family history of kidney disease, diabetes, hypertension and HIV were independently associated with both impaired eGFR and albuminuria while male gender was independently associated with only albuminuria.ConclusionsCKD is common in adult patients admitted to the internal medicine wards, but only few patients are aware of their condition. These findings highlight the need for feasible approaches to timely identify kidney disease and raise awareness on the importance of detection and early intervention in the inpatient settings.

Project description:OBJECTIVE: The structural basis of normoalbuminuric renal insufficiency in patients with type 2 diabetes remains to be elucidated. We compared renal biopsy findings in patients with type 2 diabetes and estimated glomerular filtration rate (eGFR) and measured GFR of <60 mL/min/1.73 m2, associated with either normo-, micro-, or macroalbuminuria. RESEARCH DESIGN AND METHODS: In patients with normo- (n = 8) or microalbuminuria (n = 6), renal biopsies were performed according to a research protocol. In patients with macroalbuminuria (n = 17), biopsies were performed according to clinical indication. Findings were categorized according to the Fioretto classification: category 1 (C1), normal/near normal; category 2 (C2), typical diabetic nephropathy (DN) with predominantly glomerular changes; and category 3 (C3), atypical with disproportionately severe interstitial/tubular/vascular damage and with no/mild diabetic glomerular changes. RESULTS: In our study population (mean eGFR 35 mL/min/1.73 m2), typical glomerular changes (C2) of DN were observed in 22 of 23 subjects with micro- or macroalbuminuria compared with 3 of 8 subjects with normoalbuminuria (P = 0.002). By contrast, predominantly interstitial or vascular changes (C3) were seen in only 1 of 23 subjects with micro- or macroalbuminuria compared with 3 of 8 normoalbuminuric subjects (P = 0.08). Mesangial area increased progressively from normal controls to patients with type 2 diabetes and normo-, micro-, and macroalbuminuria. Varying degrees of arteriosclerosis, although not necessarily the predominant pattern, were seen in seven of eight subjects with normoalbuminuria. CONCLUSIONS: Typical renal structural changes of DN were observed in patients with type 2 diabetes and elevated albuminuria. By contrast, in normoalbuminuric renal insufficiency, these changes were seen less frequently, likely reflecting greater contributions from aging, hypertension, and arteriosclerosis.

Project description:BackgroundAcute kidney injury (AKI) frequently co-prevails with acute coronary syndromes (ACS), which could improve post percutaneous coronary intervention (PCI). We sought to evaluate the impact of PCI on post-procedural renal function in patients with impaired baseline serum creatinine (Cr).MethodsRetrospective evaluation of 185 patients undergoing PCI with impaired basal serum Cr (≥ 1.5 mg/dl) was done, including 88 (47.5%) patients with recent ACS (≤2 weeks old) in group I and 97 (52.4%) patients in group II (stable angina or ACS >2 weeks old). Patients were classified into worsening or improving renal function based on a corresponding increase or decrease of ≥0.5 mg/dl (ΔCr) in serum Cr 24-48 h post PCI. ΔCr < 0.5 mg/dl was termed as no change.ResultsA trend towards improving renal function was seen in the study cohort (mean serum Cr: 2.37 ± 1.25 mg/dl vs 2.28 ± 1.59 mg/dl); (p = 0.09) with decrease in group I from 2.28 ± 1.09 mg/dl to 2.12 ± 1.44 mg/dl (p = 0.03) and in group II from 2.45 ± 1.38 mg/dl to 2.43 ± 1.71 mg/dl (p = 0.81). Post PCI, worsening occurred in 20/185 (10.8%) patients in the total study cohort, 5/88 (5.6%) in group I and 15/97 (15.4%) in group II (p = 0.03). Improvement in serum Cr was seen in 49/185 (26.4%) in the total study cohort, 30/88 (34.1%) in group I and 19/97 (19.6%) patients in group II (p = 0.03).Conclusion- Post PCI, only a small proportion of patients with impaired baseline creatinine showed worsening in renal function. Improved renal function was observed in at least one-third of the patients with recent ACS.

Project description:Background Hospitals participating in the national Get With The Guidelines-Resuscitation registry receive an award for high rates of adherence to quality metrics for in-hospital cardiac arrest. We sought to evaluate whether awards based on these quality metrics can be considered a proxy for performance on cardiac arrest survival. Methods and Results Among 195 hospitals with continuous participation in Get With The Guidelines-Resuscitation between 2012 and 2015, we identified 78 that received an award (Gold or Silver) for ≥85% compliance for all 4 metrics for in-hospital cardiac arrest-time to chest compressions, ≤1 minute; time to defibrillation, ≤2 minutes; device confirmation of endotracheal tube placement; and a monitored/witnessed arrest-for at least 12 consecutive months during 2014 to 2015. Award hospitals had higher cardiac arrest volumes than nonaward hospitals but otherwise had similar site characteristics. During 2014 to 2015, award hospitals had higher rates of return of spontaneous circulation for in-hospital cardiac arrest than nonaward hospitals (median [interquartile range], 71% [64%-77%] versus 66% [59%-74%]; Spearman ρ, 0.19; P=0.009). However, rates of risk-standardized survival to discharge at award hospitals (median, 25% [interquartile range, 22%-30%]) were similar to nonaward hospitals (median, 24% [interquartile range, 12%-27%]; Spearman ρ, 0.13; P=0.06). Among hospitals in the best tertile for survival to discharge in 2014 to 2015, 55.4% (36/65) did not receive an award, with poor discrimination of high-performing hospitals by award status (C statistic, 0.53). Similarly, there was only a weak association between hospitals' award status in 2014 to 2015 and their rates of survival to discharge in the preceding 2-year period (Spearman ρ, 0.16; P=0.03). Conclusions The current recognition mechanism within a national registry for in-hospital cardiac arrest captures hospital performance on return of spontaneous circulation but is not well correlated with survival to discharge. This suggests that current awards for resuscitation quality may not adequately capture hospital performance on overall survival-the outcome of greatest interest to patients.
