Telemedicine Use During the COVID-19 Pandemic by Office-based Physicians and Long-term Care Providers.

Objective: This report examines telemedicine use by office-based physicians and long-term care providers in the United States, stratified by electronic health record use and by provider or practice size. Further, it examines differences in telemedicine use before and after the COVID-19 pandemic onset among office-based physicians and assesses telemedicine use during the first year of the COVID-19 pandemic for long-term care providers.

Methods: Nationally representative estimates in this report are derived from data collected in the 2019 and 2021 National Electronic Health Records Survey, which assesses characteristics of office-based physicians, and the 2020 National Post-acute and Long-term Care Study, which assesses characteristics of adult day services centers and residential care communities.

Telemedicine Use Among Physicians by Physician Specialty: United States, 2021.

The 2019 novel coronavirus (COVID-19) pandemic led to an increase in telemedicine use among physicians, from 15.4% in 2019 to 86.5% in 2021 (1-4).

Telehealth and Public Health Practice in the United States-Before, During, and After the COVID-19 Pandemic.

Telehealth is the use of electronic information and telecommunication technologies to provide care when the patient and the provider are not in the same room at the same time. Telehealth accounted for less than 1% of all Medicare Fee-for-Service outpatient visits in the United States in 2019 but grew to account for 46% of all visits in April 2020. Changes in reimbursement and licensure policies during the COVID-19 pandemic appeared to greatly facilitate this increased use.

National Hospital Care Survey Demonstration Projects:Characteristics and Mortality Outcomes of Opioid-involved Hospital Encounters With Co-occurring Disorders.

This report demonstrates the use of National Hospital Care Survey (NHCS) data to describe characteristics of patients experiencing opioid-involved hospital encounters with co-occurring disorders, defined as lifetime diagnoses of both a substance use disorder (SUD) and a selected mental health issue (MHI), that is, diagnosed at any point in the past or during the present encounter.

National Hospital Care Survey Demonstration Projects: Examination of Inpatient Hospitalization and Risk of Mortality Among Patients Diagnosed With Pneumonia.

Objective-This report demonstrates the ability of data from the National Hospital Care Survey (NHCS) linked to the National Death Index (NDI) to provide information on inpatient hospitalizations and in-hospital and post-acute mortality among patients hospitalized for a specific condition, in this case pneumonia.

Emergency Department Visits Among Adults With Mental Health Disorders: United States, 2017-2019.

Mental health disorders, which include mental illnesses and substance use disorders, are a group of conditions characterized by alterations in thinking, emotions, or behavior (1). In 2019, 61.2 million adults aged 18 and over in the United States had a mental health disorder in the past year (2).

COVID-19 Pandemic Impact on the National Health Care Surveys.

While underscoring the need for timely, nationally representative data in ambulatory, hospital, and long-term-care settings, the COVID-19 pandemic posed many challenges to traditional methods and mechanisms of data collection. To continue generating data from health care and long-term-care providers and establishments in the midst of the COVID-19 pandemic, the National Center for Health Statistics had to modify survey operations for several of its provider-based National Health Care Surveys, including quickly adding survey questions that captured the experiences of providing care during the pandemic. With the aim of providing information that may be useful to other health care data collection systems, this article presents some key challenges that affected data collection activities for these national provider surveys, as well as the measures taken to minimize the disruption in data collection and to optimize the likelihood of disseminating quality data in a timely manner.

Respiratory Illness Emergency Department Visits in the National Hospital Care Survey and the National Hospital Ambulatory Medical Care Survey.

Purpose-This report compares emergency department (ED) visits for respiratory illness between the 2014 National Hospital Care Survey (NHCS) and the 2014 National Hospital Ambulatory Medical Care Survey (NHAMCS) to determine the potential of researching respiratory illness in EDs with non-nationally representative NHCS data. The 2014 NHCS data linked to records in the 2014-2015 National Death Index (NDI) are also described to provide results on mortality after ED visits for respiratory illness. Methods-For both surveys, encounters with respiratory illness were identified using diagnosis codes from the International Classification of Diseases, Ninth Revision, Clinical Modification (ICD-9-CM).

Opioid-involved Emergency Department Visits in the National Hospital Care Survey and the National Hospital Ambulatory Medical Care Survey.

Purpose-This report compares 2014 National Hospital Care Survey (NHCS) emergency department (ED) data with national estimates of ED visits due to opioid use (i.e., "opioid-involved visits") from the 2013-2015 National Hospital Ambulatory Medical Care Survey (NHAMCS) to determine the potential of researching the impact and outcomes of opioid use on hospital EDs with non-nationally representative NHCS data.

National Hospital Care Survey Demonstration Projects: Opioid-involved Emergency Department Visits, Hospitalizations, and Deaths.

Objective-This report demonstrates the utility of linking the restricted-use 2014 National Hospital Care Survey (NHCS), 2014-2015 National Death Index (NDI), and 2014-2015 Drug-Involved Mortality (DIM) data to study opioid-involved emergency department (ED) visits, hospitalizations, and mortality within 1 year post-discharge. Example research questions and unweighted results are presented. Results are not nationally representative.

National Hospital Care Survey Demonstration Projects: Pneumonia Inpatient Hospitalizations and Emergency Department Visits.

This report demonstrates the use of the National Hospital Care Survey (NHCS) for the study of pneumonia inpatient hospitalizations and emergency department (ED) visits. The analysis is based on unweighted data of inpatient and ED encounters from the 2014 NHCS and is intended to illustrate the capabilities of the survey, including the ability to link inpatient hospitalizations or ED visits across settings and with other data sources, once hospital participation allows for nationally representative estimates.

Identification of Substance-involved Emergency Department Visits Using Data From the National Hospital Care Survey.

This report describes the development of methods to identify emergency department (ED) visits involving substance use. Two different algorithms are compared using claims data from the 2013 National Hospital Care Survey (NHCS), a facility-based survey. While NHCS was designed to produce national estimates, this report is based on 2013 data, which are not nationally representative.

National Hospital Care Survey Demonstration Projects: Traumatic Brain Injury.

Purpose-This report demonstrates the analytical potential of the National Hospital Care Survey (NHCS) through a case study of inpatient discharges and ambulatory visits for traumatic brain injury (TBI) based on unweighted data from the 2013 NHCS of inpatient and emergency department (ED) encounters and the 2013 and 2014 NHCS for outpatient department (OPD) encounters.
