C-reactive protein (CRP) has been proposed as a contributor to the pathogenesis of coronary artery disease (CAD) and inflammatory reactions, which are associated with a decrease in serum albumin, and it has been reported that the CRP-to-serum albumin ratio (CAR) can predict CAD severity in inpatient ischemic cardiomyopathy (ICM) patients. However, the relationship between the CAR and long-term adverse outcomes in CAD patients after percutaneous coronary intervention (PCI) is still unknown.
A total of 3561 CAD patients enrolled in the Outcomes and Risk Factors of Patients with Coronary Heart Disease after PCI an investigation based on case records and follow-up (CORFCHD-ZZ), a retrospective cohort study conducted from January 2013 to December 2017, and 1630 patients meeting the study inclusion criteria were divided into two groups based on the CAR (CAR < 0.186; n = 1301 and CAR ≥ 0.186; n = 329). The primary outcome was long-term mortality, including all-cause mortality (ACM) and cardiac mortality. The average follow-up time was 37.59 months.
We found that there were significant differences between the two groups in the incidences of ACM (P < 0.001) and cardiac mortality (P = 0.003). Cox multivariate regression analyses demonstrated that CAR was an independent predictor of ACM [hazard ratio, 2.678; (95% confidence interval (CI), 1.568-4.576); P < 0.001] and cardiac mortality (hazard ratio, 2.055; 95% CI, 1.056-3.998; P = 0.034) in CAD patients after PCI.
This study revealed that the CAR is an independent and novel predictor of long-term adverse outcomes in CAD patients who have undergone PCI.

Health care organizations are increasingly employing social workers to address patients' social needs. However, social work (SW) activities in health care settings are largely captured as text data within electronic health records (EHRs), making measurement and analysis difficult. This study aims to extract and classify, from EHR notes, interventions intended to address patients' social needs using natural language processing (NLP) and machine learning (ML) algorithms.
Secondary data analysis of a longitudinal cohort.
We extracted 815 SW encounter notes from the EHR system of a federally qualified health center. We reviewed the literature to derive a 10-category classification scheme for SW interventions. We applied NLP and ML algorithms to categorize the documented SW interventions in EHR notes according to the 10-category classification scheme.
Most of the SW notes (n = 598; 73.4%) contained at least 1 SW intervention. The most frequent interventions offered by social workers included care coordinatinto the most needed social interventions in the patient population served by their organizations. Such information can be applied in managerial decisions related to SW staffing, resource allocation, and patients' social needs.
Electronic consultations, or e-consults, between primary care providers and specialists have been shown to improve access to specialty care, shorten wait times, and reduce outpatient visits. N-Methyl-D-aspartic acid order The objective of this study was to evaluate differences in health care costs between patients who received an electronic specialty consultation and patients who received a face-to-face specialty consultation.
Retrospective cohort evaluation of patients who received a specialty consultation in the Veterans Health Administration during 2016.
Patients who received an e-consult were matched 11 to patients who received a face-to-face consultation using propensity scores. Total, outpatient, and inpatient health care costs over 3 and 6 months following the specialty consultation were compared using a generalized linear model with a gamma distribution and log link.
e-Consults accounted for 1.8% (urology) to 9.6% (hematology) of specialty consultations, on average. Across 11 specialties, patients receiving an e-consult had significantly lower health care costs compared with patients receiving a face-to-face consultation, ranging from 3.6% (cardiology) to 30.7% (hematology) lower. This was largely driven by differences in outpatient costs. Patients receiving an e-consult had significantly lower outpatient costs for all specialties except cardiology, ranging from 6.9% (endocrinology) to 31.2% (hematology) lower. Three-month inpatient costs among those who received an e-consult were significantly lower only in cardiology (5.2%), nephrology (9.3%), pulmonary (13.0%), and gastroenterology (14.3%).
Electronic specialty consultations are a potential mechanism to reduce health care costs and promote the efficient use of health care resources.

Palliative care has been demonstrated to have positive effects for patients, families, health care providers, and health systems. Early identification of patients who are likely to benefit from palliative care would increase opportunities to provide these services to those most in need. This study predicted all-cause mortality of patients as a surrogate for patients who could benefit from palliative care.
Claims and electronic health record (EHR) data for 59,639 patients from a large integrated health care system were utilized.
A deep learning algorithm-a long short-term memory (LSTM) model-was compared with other machine learning models deep neural networks, random forest, and logistic regression. We conducted prediction analyses using combined claims data and EHR data, only claims data, and only EHR data, respectively. In each case, the data were randomly split into training (80%), validation (10%), and testing (10%) data sets. The models with different hyperparameters were trained using the training data, and the model with the best performance on the validation data was selected as the final model. The testing data were used to provide an unbiased performance evaluation of the final model.
In all modeling scenarios, LSTM models outperformed the other 3 models, and using combined claims and EHR data yielded the best performance.
LSTM models can effectively predict mortality by using a combination of EHR data and administrative claims data. The model could be used as a promising clinical tool to aid clinicians in early identification of appropriate patients for palliative care consultations.
