RESUMEN
OBJECTIVE: Using augmented intelligence clinical decision tools and a risk score-guided multidisciplinary team-based care process (MTCP), this study evaluated the MTCP for heart failure (HF) patients' 30-day readmission and 30-day mortality across 20 Intermountain Healthcare hospitals. BACKGROUND: HF inpatient care and 30-day post-discharge management require quality improvement to impact patient health, optimize utilization, and avoid readmissions. METHODS: HF inpatients (Nâ¯=â¯6182) were studied from January 2013 to November 2016. In February 2014, patients began receiving care via the MTCP based on a phased implementation in which the 8 largest Intermountain hospitals (accounting for 89.8% of HF inpatients) were crossed over sequentially in a stepped manner from control to MTCP over 2.5 years. After implementation, patient risk scores were calculated within 24 hours of admission and delivered electronically to clinicians. High-risk patients received MTCP care (nâ¯=â¯1221), while lower-risk patients received standard HF care (nâ¯=â¯1220). Controls had their readmission and mortality scores calculated retrospectively (high risk: nâ¯=â¯1791; lower risk: nâ¯=â¯1950). RESULTS: High-risk MTCP recipients had 21% lower 30-day readmission compared to high-risk controls (adjusted Pâ¯=â¯.013, HRâ¯=â¯0.79, CIâ¯=â¯0.66, 0.95) and 52% lower 30-day mortality (adjusted Pâ¯<â¯.001, HRâ¯=â¯0.48, CIâ¯=â¯0.33, 0.69). Lower-risk patients did not experience increased readmission (adjusted HRâ¯=â¯0.88, Pâ¯=â¯.19) or mortality (adjusted HRâ¯=â¯0.88, Pâ¯=â¯.61). Some utilization was higher, such as prescription of home health, for MTCP recipients, with no changes in length of stay or overall costs. CONCLUSIONS: A risk score-guided MTCP was associated with lower 30-day readmission and 30-day mortality in high-risk HF inpatients. Further evaluation of this clinical management approach is required.

Improving 30-day readmission continues to be problematic for most hospitals. This study reports the creation and validation of sex-specific inpatient (i) heart failure (HF) risk scores using electronic data from the beginning of inpatient care for effective and efficient prediction of 30-day readmission risk. METHODS: HF patients hospitalized at Intermountain Healthcare from 2005 to 2012 (derivation: n=6079; validation: n=2663) and Baylor Scott & White Health (North Region) from 2005 to 2013 (validation: n=5162) were studied. Sex-specific iHF scores were derived to predict post-hospitalization 30-day readmission using common HF laboratory measures and age. Risk scores adding social, morbidity, and treatment factors were also evaluated. RESULTS: The iHF model for females utilized potassium, bicarbonate, blood urea nitrogen, red blood cell count, white blood cell count, and mean corpuscular hemoglobin concentration; for males, components were B-type natriuretic peptide, sodium, creatinine, hematocrit, red cell distribution width, and mean platelet volume. Among females, odds ratios (OR) were OR=1.99 for iHF tertile 3 vs. 1 (95% confidence interval [CI]=1.28, 3.08) for Intermountain validation (P-trend across tertiles=0.002) and OR=1.29 (CI=1.01, 1.66) for Baylor patients (P-trend=0.049). Among males, iHF had OR=1.95 (CI=1.33, 2.85) for tertile 3 vs. 1 in Intermountain (P-trend <0.001) and OR=2.03 (CI=1.52, 2.71) in Baylor (P-trend < 0.001). Expanded models using 182-183 variables had predictive abilities similar to iHF. CONCLUSIONS: Sex-specific laboratory-based electronic health record-delivered iHF risk scores effectively predicted 30-day readmission among HF patients. Efficient to calculate and deliver to clinicians, recent clinical implementation of iHF scores suggest they are useful and useable for more precise clinical HF treatment.

OBJECTIVE: Risk of morbidity and mortality after coronary artery bypass graft surgery (CABG) is higher in patients with clinical diabetes mellitus (DM). We evaluated whether outcomes are affected by postoperative hyperglycemia in CABG patients independent of preoperative DM diagnosis. RESEARCH DESIGN AND METHODS: A total of 2297 consecutive CABG patients were studied. The first glucose value after surgery completion (mean 15 min) was tested as a predictor of outcome. Primary outcome variables were prolonged ventilation (>24 h), deep sternal wound infection, renal failure, permanent stroke, any reoperation, length of stay (>14 days) and mortality. All outcomes except for prolonged ventilation and length of stay were tracked out to 30 days postoperatively. Patients were stratified by glycemic control: Low (glucose <80), normal (referent, glucose 80-110), high (glucose 111-200) and very high (glucose >200 mg/dl). Multivariable logistic regression was used to determine the independent predictive value of glycemic groups, adjusted for outcome specific risk scores from the Society of Thoracic Surgeons model. RESULTS: Patient distribution among groups low through very high were 44 (1.9%), 476 (20.7%), 1425 (62.0%) and 352 (15.3%). Greater complication rates were noted in the very high group when compared with the referent group: prolonged ventilation (adjusted odds ratio (OR)=2.66, P<.001), length of stay >14 days (adjusted OR=2.06, P=.004) and mortality (adjusted OR=7.71, P<.001). CONCLUSION: Patients with blood glucose values >200 mg/dl immediately after CABG had an increased risk of complications, including mortality, independent of a clinical diagnosis of DM. This study documents the high risk associated with early postoperative hyperglycemia in this group, suggesting the need for prospective trials of glycemic control.

BACKGROUND: In 2002, the Joint Commission on Accreditation of Healthcare Organizations (JCAHO) established four heart failure (HF) core measures to standardize and improve health care quality in the United States. Although adherence to these HF care processes may be improving, their collective impact on survival is not yet settled. METHODS: JCAHO HF measures were implemented within a 20-hospital health care system. Eligible patients had a principal discharge diagnosis of HF. Metrics representing compliance with these measures were derived and their relationship with 1-year survival was examined using an adjusted Cox proportional hazards regression. RESULTS: A total of 2958 patients met study criteria. The average age was 73 years, 50% were male, and 9.9% were smokers. One-year survival benefits were seen in an item-by-item evaluation of HF measures for angiotensin-converting enzyme inhibitor/angiotensin receptor blocker therapy (hazard ratio [HR] = 0.69), left ventricular function assessment (HR = 0.83), and patient education (HR = 0.79). When assessed collectively, improved survival was seen among patients eligible for two (HR = 0.53), three (HR = 0.36), or four HF measures (HR = 0.65). Further, we found a positive and incremental relationship between the degree of adherence and survival (P = .008). CONCLUSION: Adherence to JCAHO HF core measures is associated with improved 1-year survival after HF hospitalization. This validates these simple and effective performance measures and justifies efforts to implement them in all eligible patients with HF.

PURPOSE: Heart failure (HF) patients often have comorbid conditions that confound management and adversely affect prognosis. The purpose of this study was to determine whether the obesity paradox is also present in hospitalized HF patients in an integrated healthcare system. DATA SOURCES: A cohort of 2707 patients with a primary diagnosis of HF was identified within an integrated, 20-hospital healthcare system. Patients were identified by ICD-9 codes or a left ventricular ejection fraction < or =40% dating back to 1995. Body mass index (BMI) was calculated using the first measured height and weight when hospitalized with HF. Survival rates were calculated using Kaplan Meier estimation. Hazard ratios for 3-year mortality with 95% confidence intervals were assessed using Cox regression, controlling for age, gender, and severity of illness at time of diagnosis. CONCLUSIONS: Three-year survival rates paradoxically improved for patients with increasing BMI. Survival rates for the larger three BMI quartiles were significantly better than for the lowest quartile after adjusting for severity of illness, age, and gender. IMPLICATIONS FOR PRACTICE: While obesity increases the risk of developing HF approximately twofold, reports involving stable outpatients suggest that obesity is associated with improved survival after the development of HF. This finding is paradoxical because obesity increases the risk and worsens the prognosis of other cardiovascular diseases.
