Hospitalization Rates and Characteristics of Patients Hospitalized with Laboratory-Confirmed Coronavirus Disease 2019 — Covid-NET, 14 States, March 1–30, 2020
Since SARS-CoV-2, the novel coronavirus that causes coronavirus disease 2019 , was first detected in December 2019 (1), approximately 1.3 million cases have been reported worldwide (2), including approximately 330,000 in the United States (3). To conduct population-based surveillance for laboratory-confirmed COVID-19-associated hospitalizations in the United States, the COVID-19-Associated Hospitalization Surveillance Network (COVID-NET) was crea…
Parental Refusal of Vitamin K and Neonatal Preventive Services
Bias with respect to socioeconomic status
In 2010, 13-valent pneumococcal conjugate vaccine (PCV13) was introduced in the US for prevention of invasive pneumococcal disease in children. Individual-level socioeconomic status (SES) is a potential confounder of the estimated effectiveness of PCV13 and is often controlled for in observational studies using zip code as a proxy. We assessed the utility of zip code matching for control of SES in a post-licensure evaluation of the effectiveness …
Seasonal Influenza Morbidity Estimates Obtained From Telephone Surveys, 2007
Objectives. We assessed telephone surveys as a novel surveillance method, comparing data obtained by telephone with existing national influenza surveillance systems, and evaluated the utility of telephone surveys. Methods. We used the 2007 Behavioral Risk Factor Surveillance System (BRFSS) and the 2007 National Immunization Survey–Adult (NIS–Adult) to estimate the incidence of influenza-like illness (ILI), medically attended ILI, provider-diagnos…
Socioeconomic and Racial/Ethnic Disparities in the Incidence of Bacteremic Pneumonia Among US Adults
Objectives. We examined associations between the socioeconomic characteristics of census tracts and racial/ethnic disparities in the incidence of bacteremic community-acquired pneumonia among US adults. Methods. We analyzed data on 4870 adults aged 18 years or older with community-acquired bacteremic pneumonia identified through active, population-based surveillance in 9 states and geocoded to census tract of residence. We used data from the 2000…
Reducing antipsychotic drug prescribing for nursing home patients
We conducted a statewide, controlled trial of the efficacy of an educational visit in reducing antipsychotic drug prescribing for nursing home patients. Frequent antipsychotic drug prescribers were visited by a trained physician counselor who stressed known drug risks for elderly patients and suggested techniques for reducing antipsychotic drug use. Although well-received, the visit did not reduce antipsychotic drug prescribing. This negative fin…
Disease surveillance and emergency services at the 1982 World's Fair
We designed a special surveillance system to detect health complaints of visitors to the 1982 World's Fair. Heat-related illness occurred during the first month of the Fair but was substantially reduced by public education, environmental modification, and provision of additional water fountains. There was no disruption of emergency health services in the communities surrounding the Fair. Advance planning and the provision of on-site medical servi…
Differences Between Female and Male Children in the Receipt of Prescribed Psychotropic and Controlled-Analgesic Drugs
This study describes the differences between male and female children in the receipt of prescriptions for psychotropic and controlled-analgesic drugs in office practice. The study encompassed 341,422 children of ages 0 through 17 years enrolled in the Tennessee Medicaid program during the 5 years 1977-1981. These children made 1,342,573 office visits and received 1,636,127 prescriptions during the study. There were 18,023 (5.3%) children who rece…

An outbreak of foodborne hepatitis A
In April 1981, an outbreak of hepatitis A occurred among state legislators in Tennessee. Although the number of cases was small, we traced the source to a food handler who served cold meats and cheese. This investigation demonstrates the value of rapid serologic testing using a radioimmunoassay technique and matched case-control analysis to identify small foodborne outbreaks of hepatitis A

A study of antipsychotic drug use in nursing homes
We reviewed 384,326 prescriptions for 5,902 Medicaid patients residing continuously for one year in 173 Tennessee nursing homes. Of these patients, 43 per cent received antipsychotic drugs; 9 per cent were chronic recipients (received at least 365 daily doses per year). Of the 1,580 physicians who cared for these patients, 42 per cent prescribed antipsychotic medication. Physicians with large nursing home practices (10 or more patients) prescribe…
Maternal Mortality in Michigan
An analysis was performed of direct maternal mortality over 22 years (1950 through 1971) in the state of Michigan. The overall direct maternal mortality rate fell from 5.0/10,000 live births in 1950 to 1.5 in 1971. The rate among nonwhites was more than four times greater than among whites and the difference in relative risk did not narrow over the 22 years. Mortality rates increased with increasing maternal age but not with increasing parity. Nu…

Medicaid Records as a Valid Data Source; The Tennessee Experience
Health care researchers rarely employ Medicaid claim files as a data base, in part because they are designed to serve fiscal and administrative ends. Indeed, some investigators have emphasized the deficiencies in such records. In contrast, we have found Tennessee Medicaid data to be suitable for research. A statewide automated data processing system reduces the occurrence of many of the errors noted by others. Further, analysis of the July 1974 m…
