United States Centers for Disease Control and Prevention support for influenza surveillance, 2013-2021.

Objective: To assess the stability of improvements in global respiratory virus surveillance in countries supported by the United States Centers for Disease Control and Prevention (CDC) after reductions in CDC funding and with the stress of the coronavirus disease 2019 (COVID-19) pandemic. Methods: We assessed whether national influenza surveillance systems of CDC-funded countries: (i) continued to analyse as many specimens between 2013 and 2021; (ii) participated in activities of the World Health Organization's (WHO) Global Influenza Surveillance and Response System; (iii) tested enough specimens to detect rare events or signals of unusual activity; and (iv) demonstrated stability before and during the COVID-19 pandemic. We used CDC budget records and data from the WHO Global Influenza Surveillance and Response System. Findings: While CDC reduced per-country influenza funding by about 75% over 10 years, the number of specimens tested annually remained stable (mean 2261). Reporting varied substantially by country and transmission zone. Countries funded by CDC accounted for 71% (range 61-75%) of specimens included in WHO consultations on the composition of influenza virus vaccines. In 2019, only eight of the 17 transmission zones sent enough specimens to WHO collaborating centres before the vaccine composition meeting to reliably identify antigenic variants. Conclusion: Great progress has been made in the global understanding of influenza trends and seasonality. To optimize surveillance to identify atypical influenza viruses, and to integrate molecular testing, sequencing and reporting of severe acute respiratory syndrome coronavirus 2 into existing systems, funding must continue to support these efforts.

Injury prevention counseling for adults: have we made progress?

Injuries are a leading cause of morbidity and mortality in the United States. Physicians are a trusted source that can disseminate information about the prevention of injury and violence. This study used the second Injury Control and Risk Survey to report the national prevalence of healthcare provider injury prevention counseling to adults. Results indicate that overall 1 in 5 adults who visited a healthcare provider received some counseling on injury prevention. Counseling prevalence varied by injury topic and patient demographic characteristics. Many people who could benefit from counseling are not receiving it, even among those who had visited a healthcare provider.

Epidemiology of homicide-suicide events: Oklahoma, 1994-2001.

In Oklahoma, all nonnatural deaths must be reported to the Office of the Chief Medical Examiner (ME), whose trained investigators report cause of death using a centralized, statewide, standardized reporting system. The purpose of this study was to determine temporal trends of Oklahoma homicide-suicide events and characterize the epidemiology of these events. By reviewing all ME reports of homicides and suicides from 1994 through 2001, we identified 73 homicide-suicide events resulting in 73 suicides and 89 homicides. Suicidal perpetrators of homicide-suicide events were most often white men aged >or=30 years who killed a current or ex-spouse or intimate partner. Homicide victims tended to be younger women the same race as their killer. Firearms were the predominant method of death in both homicides and suicides, with handguns used most frequently. Divorce/estrangement was the main contributing factor to these events, and the most common relationship type was possessive. The existence of a statewide, centralized, and computerized ME system and the ability to access the detailed information in the ME narratives were critical to identifying homicide-suicide events and obtaining the type of detailed information necessary to fully investigate these events.

Association between health insurance coverage of office visit and cancer screening among women.

BACKGROUND: Little is known regarding the nuances of insurance benefit design that may affect the receipt of clinical preventive services. OBJECTIVE: To evaluate whether differences in insurance coverage of physician office visits influences the receipt of cancer screening in women who have full coverage for the screening services. DESIGN: Cohort study of women enrolled in fee-for-service (FFS) or Preferred Provider Organization (PPO) health plans, where FFS plans have less generous office visit coverage, for the period 1995 to 1997. SETTINGS AND PARTICIPANTS: General Motors Corporation's employees and their dependents. MAIN OUTCOME MEASURES: Papanicolaou and mammography rates in women aged 21 to 64 years (n = 139,294) and 52 to 64 years (n = 56,554), respectively. RESULTS: Compared with FFS plans, enrollees in PPO plans were significantly more likely to obtain a Papanicolaou smear and mammogram (adjusted relative risk [RRa] = 1.22; 95% CI, 1.21-1.24; and RRa, 1.17; 95% CI, 1.15-1.18, respectively). The association was more pronounced among hourly individuals (RRa, 1.27; 95% CI, 1.26-1.29 for Papanicolaou smears; RRa, 1.17; 95% CI, 1.16-1.19 for mammograms) than among salaried individuals (RRa, 1.10; 95% CI, 1.08-1.12 for Papanicolaou smears and RRa, 1.10; 95% CI, 1.06-1.12 for mammograms), corresponding to a greater differential in office visit coverage among the hourly group. CONCLUSIONS: Benefit structure appears to have an important effect on receipt of cancer screening in women. The findings highlight the need to ensure that future reforms of the health care system do not adversely affect the use of preventive services.
