Colorado became the first state to make laboratory-confirmed influenza-associated hospitalizations a case-based reportable condition in 2004. We summarized surveillance for influenza hospitalizations in Colorado during the first 4 recorded influenza seasons (2004–2008). We highlight the similarities and differences among influenza seasons; no 2 seasons were entirely the same. The 2005–06 influenza season had 2 distinct waves of activity (types A and B), the 2006–07 season was substantially later and milder, and 2007–08 had substantially greater influenza B activity. The case-based surveillance for influenza hospitalizations provides information regarding the time course of seasonal influenza activity, reported case numbers and population-based rates by age group and influenza virus type, and a measure of relative severity. Influenza hospitalization surveillance provides more information about seasonal influenza activity than any other surveillance measure (e.g., surveillance for influenza-like illness) currently in widespread use among states. More states should consider implementing case-based surveillance for influenza hospitalizations.  相似文献

ObjectivesConduct a needs assessment among post-acute and long-term care (PA-LTC) stakeholder groups to identify (1) research topics of highest priority and (2) perspectives on research, including concerns/barriers to conducting research in the PA-LTC setting.DesignMixed methods multistakeholder engagement process. Needs assessment conducted with tailored strategies per stakeholder group: interview, survey, and focus group.Setting and ParticipantsFour stakeholder groups—medical directors/providers (n = 89), administrative leadership (n = 5), frontline staff (n = 17), and family members of residents and residents themselves (n = 11)—were recruited from the Colorado PA-LTC community through an academic-community partnership between the University of Colorado and Colorado Medical Directors Association.Main Outcome(s)Stakeholder perspectives on research and high priority PA-LTC research topics.ResultsResearch priorities common across stakeholder groups included polypharmacy (overuse of medication generally and overuse of antibiotics specifically), care transitions, mental health (including dementia, Alzheimer's disease, behaviors), chronic pain, urinary tract infection, and quality of life issues. Providers specifically prioritized heart failure, Parkinson's, and other chronic illnesses. Administrators and directors of nurses emphasized hospitalizations. Staff prioritized medication/therapy compliance. Families/residents prioritized neurologic disease. Concerns included staff burden, consenting process, privacy, and family involvement.Conclusions/ImplicationsPA-LTC patients have a lot to offer as participants and decision makers in research, frontline staff are enthusiastic about participation, family members want to be involved, and providers value research findings in their practice but need a more supportive environment to produce and participate in research.  相似文献

To determine the incidence of Clostridium difficile infection during 2007, we examined infection in adult inpatient and outpatient members of a managed-care organization. Incidence was 14.9 C. difficile infections per 10,000 patient-years. Extrapolating this rate to US adults, we estimate that 284,875 C. difficile infections occurred during 2007.  相似文献
