The HITECH Act aimed to leverage Electronic Health Records (EHRs) to improve efficiency, quality, and patient safety. Patient safety and EHR use have been understudied, making it difficult to determine if EHRs improve patient safety. The objective of this study was to determine the impact of EHRs and attesting to Meaningful Use (MU) on Patient Safety Indicators (PSIs).

It is unclear if national investments of the HITECH Act have resulted in significant improvements in care processes and outcomes by making "Meaningful Use (MU)" of Electronic Health Record (EHR) systems. The objective of this study is to determine the impact of EHRs and MU on inpatient quality. We used inpatient hospitalization data, American Hospital Association annual survey, and the Centers for Medicare and Medicaid Services attestation records to study the impact of EHRs on inpatient quality composite scores.

Background: Prescription drug use has soared in the USA within the last two decades. Prescription drugs can impair motor skills essential for the safe operation of a motor vehicle, and therefore can affect traffic safety. As one of the epicentres of the opioid epidemic, Florida has been struck by high opioid misuse and overdose rates, and has concurrently suffered major threats to traffic disruptions safety caused by driving under the influence of drugs.

Background: Although early follow-up after discharge from an index admission (IA) has been postulated to reduce 30-day readmission, some researchers have questioned its efficacy, which may depend upon the likelihood of readmission at a given time and the health conditions contributing to readmissions.

Objective: To investigate the relationship between post-discharge services utilization of different types and at different timepoints and unplanned 30-day readmission, length of stay (LOS), and inpatient costs.

Design, Setting, And Participants: The study sample included 583,199 all-cause IAs among 2014 Medicare fee-for-service beneficiaries that met IA inclusion criteria.

Background: Emergency departments (EDs) have become entry points for treating behavioural health (BH) conditions, thereby rendering the evaluation of their utilisation necessary.

Objectives: This study estimated behavioural-related hospital-based ED visits and outcomes of leaving against medical advice as well as the incurred charges within the primarily rural State of Nebraska. Also, the study correlated behavioural workforce distribution and location of EDs with ED utilisation.

Objectives: Public health accreditation is a 7-step process that starts with a period of preapplication during which a health department assesses its readiness for accreditation. However, no tools with established reliability and validity that quantitatively measure a local health department's (LHD's) capacity for accreditation are available to complete this initial step. We developed and validated a survey to measure accreditation capacity for LHDs.

Aortic stenosis (AS) and regurgitation (AR) may be treated with surgical aortic valve replacement (SAVR), transcatheter AVR (TAVR), or medical therapy (MT). Data are lacking regarding the usage of SAVR, TAVR, and MT for patients hospitalized with aortic valve disease and the characteristics of the patients and hospitals associated with each therapy. From the Nationwide Readmissions Database, we determined utilization trends for SAVR, TAVR, and MT in patients with aortic valve disease admitted from 2012 to 2016 for valve replacement, heart failure, unstable angina, non-ST-elevation myocardial infarction, or syncope.

Background: Efforts to reduce hospital readmissions include post-discharge interventions related to the illness treated during the index hospitalization (IH). These efforts may be inadequate because readmissions are precipitated by a wide range of health conditions unrelated to the primary diagnosis of the IH.

Objective: To investigate the relationship between post-discharge health services utilization for the same or a different diagnosis than the IH and unplanned 30-day readmission.

Background: In 2015, the Hospital Readmissions Reduction Program mandated financial penalties to hospitals with greater rates of readmissions for certain conditions. Alcohol-related disorders (ARD) are the fourth leading cause of 30-day readmissions. Yet, there is a dearth of national-level research to identify high-risk patient populations and predictors of 30-day readmission.

School-based health centers (SBHCs) have been suggested as potential medical homes, yet minimal attention has been paid to measuring their patient-centered medical home (PCMH) implementation. The purposes of this article were to (1) develop an index to measure PCMH attributes in SBHCs, (2) use the SBHC PCMH Index to compare PCMH capacity between PCMH certified and non-PCMH SBHCs, and (3) examine differences in index scores between SBHCs based in schools with and without adolescents. A total of six PCMH dimensions in the SBHC PCMH Index were identified through factor analysis.
