Context: Self-monitoring blood pressure (SMBP) programs are an evidence-based hypertension management intervention facilitated through telehealth. SMBP programs can provide a continuum of care beyond a clinical setting by facilitating hypertension management at home; however, equitable access to SMBP is a concern.

Objectives: To evaluate the implementation of telehealth SMBP programs using an equity lens in 5 federally qualified health centers (FQHCs) in Massachusetts (MA).

Objectives: The launch of state certification for community health workers (CHWs) in Massachusetts in 2018 aimed to promote and champion this critical workforce. However, concerns exist about unintentional adverse effects of certification. Given this, we conducted 2 cross-sectional surveys to evaluate this certification policy.

Introduction: Electronic health records (EHRs) are increasingly being leveraged for public health surveillance. EHR-based small area estimates (SAEs) are often validated by comparison to survey data such as the Behavioral Risk Factor Surveillance System (BRFSS). However, survey and EHR-based SAEs are expected to differ.

Background: Professional certification of community health workers (CHWs) is a debated topic. Although intended to promote CHWs, certification may have unintended impacts given the grassroots nature of the workforce. As such, both intended effects and unintended adverse effects should be carefully evaluated.

Acute stroke care begins before hospital arrival, and several prehospital factors are critical in influencing overall patient care and poststroke outcomes. This topical review provides an overview of the state of the science on prehospital components of stroke systems of care and how emergency medical services systems may interact in the system to support acute stroke care. Topics include layperson recognition of stroke, prehospital transport strategies, networked stroke care, systems for data integration and real-time feedback, and inequities that exist within and among systems.

Objective: Arrival by emergency medical services (EMS) and prenotification among ischemic stroke patients are well-established to improve the timeliness and quality of stroke care, yet the association of prenotification with in-hospital mortality has not been previously described. Our cross-sectional study aimed to assess the association between EMS prenotification and in-hospital mortality for patients with acute ischemic stroke or transient ischemic attack.

Methods: We analyzed data from the Massachusetts Paul Coverdell National Acute Stroke Program registry.

Background: Patients with stroke are frequently transferred between hospitals. This may have implications on the quality of care received by patients; however, it is not well understood how the characteristics of sending and receiving hospitals affect the likelihood of a transfer event. Our objective was to identify hospital characteristics associated with sending and receiving patients with stroke.

Objectives: The outbreak of COVID-19 in Massachusetts may have reduced ambulatory care access. Our study aimed to quantify this impact among populations with severely uncontrolled diabetes and hypertension; these populations are at greatest risk for adverse outcomes caused by disruptions in care.

Methods: We analyzed multidisciplinary ambulatory electronic health record data from MDPHnet.

Objective: Administrative databases seldom include detailed clinical variables and vital status, limiting the scope of population-based studies. We demonstrate a comprehensive process for integrating 3 databases (all-payor inpatient hospitalizations, clinical acute stroke registry and vital statistics) into a single statewide ischemic stroke database.

Materials And Methods: The 3 Massachusetts databases spanned 2007-2017.

Objectives: Waiting times for secondary care psychological therapy remain a 'blind spot' in serious mental illness (SMI) provision, and their reduction is a priority within the National Health Service (NHS) Five Year Forward View. The paper describes the eradication of waiting times within a community-based NHS service and the effectiveness of strategies whilst examining help-seeking behaviour, compliance and therapeutic need.

Methods: Analyses are reported for treatment compliance and therapeutic outcomes for 208 waiting-list cohort individuals seen by the SMI psychology service over an 18-month period between October 2014 and March 2016.

Automated analysis of electronic health record (EHR) data is a complementary tool for public health surveillance. Analyzing and presenting these data, however, demands new methods of data communication optimized to the detail, flexibility, and timeliness of EHR data.RiskScape is an open-source, interactive, Web-based, user-friendly data aggregation and visualization platform for public health surveillance using EHR data.

Collaboration between emergency medical services (EMS) and hospitals receiving stroke patients is critical to ensure prompt, effective treatment, and is a key component of the stroke systems of care (SSoC). The goal of our study was to evaluate the association between presentation by EMS and EMS prenotification with odds of receiving Tissue-type Plasminogen Activator (IV-tPA) in a state implementing SSoC while rigorously accounting for missing data. We utilized data from the Massachusetts Paul Coverdell Stroke Registry for this study, and analyzed adult patients presenting with ischemic stroke to Massachusetts Coverdell hospitals between 2016 and 2018.

Because quality improvement metrics and treatment guidelines are used to conduct research, evaluate care quality, and assess population health, they should, ideally, align. We used electronic medical record data to analyze variation between blood pressure control estimates calculated by using thresholds derived from National Quality Forum 0018 (NQF 0018) and Joint National Committee (JNC) treatment guidelines in a cohort of patients with hypertension. Percentage of patients with controlled blood pressure derived from each quality improvement or treatment guideline cutoff varied up to 16.

Background: Initial serum lactate has been associated with mortality in trauma patients. It is not known if lactate clearance is predictive of death in a broad cohort of trauma patients.

Methods: We enrolled 4,742 trauma patients who had an initial lactate measured during a 10-year period.
