The PACIC appears to be a practical instrument that is reliable and has face, construct, and concurrent validity. The resulting questionnaire is in the public domain, and recommendations for its use in research and quality improvement are outlined.
Streptococcus pneumoniae is the chief cause of pneumonia in older adults, but it remains unclear whether use of the pneumococcal polysaccharide vaccine alters the overall risk of community-acquired pneumonia. In a large population of older adults, we assessed the effectiveness of the pneumococcal vaccine. methods In this retrospective cohort study, 47,365 Group Health Cooperative members 65 years of age or older were assessed over a three-year period. The primary outcomes were hospitalization because of community-acquired pneumonia (validated by chart review), pneumonia in patients who were not hospitalized ("outpatient pneumonia," determined from administrative data sources), and pneumococcal bacteremia. The association between pneumococcal vaccination and the risk of each outcome was evaluated by means of multivariate Cox proportional-hazards models, with adjustment for age, sex, nursinghome residence or nonresidence, smoking status, medical conditions, and receipt or nonreceipt of influenza vaccine. results During the study period, 1428 cohort members were hospitalized with communityacquired pneumonia, 3061 were assigned a diagnosis of outpatient pneumonia, and 61 had pneumococcal bacteremia. Receipt of the pneumococcal vaccine was associated with a significant reduction in the risk of pneumococcal bacteremia (hazard ratio, 0.56; 95 percent confidence interval, 0.33 to 0.93) but a slightly increased risk of hospitalization for pneumonia (hazard ratio, 1.14; 95 percent confidence interval, 1.02 to 1.28). Pneumococcal vaccination did not alter the risk of outpatient pneumonia (hazard ratio, 1.04; 95 percent confidence interval, 0.96 to 1.13) or of any case of community-acquired pneumonia, whether or not it required hospitalization (hazard ratio, 1.07; 95 percent confidence interval, 0.99 to 1.14). conclusions These findings support the effectiveness of the pneumococcal polysaccharide vaccine for the prevention of bacteremia, but they suggest that alternative strategies are needed to prevent nonbacteremic pneumonia, which is a more common manifestation of pneumococcal infection in elderly persons.
All states offer telephone quit lines but they are under-used in part because of the costs associated with promotion. Offering nicotine replacement therapy (NRT) as well as behavioral counseling can increase treatment participation and abstinence rates, but is expensive. Offering less than a full NRT 8-week course can also generate calls to the quit line but less is known about its impact on program outcomes. In October 2004, Oregon--a state with over 3 million people, 500,000 smokers, and a state-funded quit line--introduced the Free Patch Initiative: a free 2-week introductory supply of NRT with phone counseling offered to all callers. We examined the impact of this intervention among insured callers. Most (97.2%) requested free patches, 86.2% used them, and 47.2% obtained additional patches on their own. Six-month outcome data were obtained from insured quit line participants before (n = 268) and after (n = 614) the Initiative launched. Compared with pre-Initiative controls, Free Patch participants were more satisfied with the quit line (84.8% vs. 89.8%; p = .04) and had higher 7-day quit rates using the assumption that eligible nonrespondents are smokers (9.3% vs. 17.0%, OR = 2.0; 95% CI 1.4-2.8) and using respondent only analysis (19% vs. 33.6%, OR = 2.15; 95% CI 1.52-3.04). Offering a free direct mail starter pack of NRT along with telephone counseling is an effective, cost-sharing method for promoting quit line use, enhancing participant satisfaction, and increasing the reach and effectiveness of quit lines among quit line callers with health insurance.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
