Racial differences in influenza vaccination among older americans 1996–2000: longitudinal analysis of the Health and Retirement Study (HRS) and the Asset and Health Dynamics Among the Oldest Old (AHEAD) survey

BACKGROUND: Influenza is a common and serious public health problem among the elderly. The influenza vaccine is safe and effective. METHODS: The purpose of the study was to determine whether frequencies of receipt vary by race, age group, gender, and time (progress from 1995/1996 to 2000), and whether any racial differences remain in age groups covered by Medicare. Subjects were selected from the Health and Retirement Study (HRS) (12,652 Americans 50–61 years of age (1992–2000)) and the Asset and Health Dynamics Among the Oldest Old (AHEAD) survey (8,124 community-dwelling seniors aged 70+ years (1993–2000)). Using multivariate logistic regression, adjusting for potential confounders, we estimated the relationship between race, age group, gender, time and the main outcome measure, receipt of influenza vaccination in the last 2 years. RESULTS: There has been a clear increase in the unadjusted rates of receipt of influenza vaccination for all groups from 1995/1996 to 2000. However, the proportions immunized are 10–20% higher among White than among Black elderly, with no obvious narrowing of the racial gap from 1995/1996 to 2000. There is an increase in rates from age 50 to age 65. After age 70, the rate appears to plateau. In multivariate analyses, the racial difference remains after adjusting for a series of socioeconomic, health, and health care related variables. (HRS: OR = 0.63 (0.55–0.72), AHEAD: OR = 0.55 (0.44–0.66)) CONCLUSIONS: There is much work left if the Healthy People 2010 goal of 90% of the elderly immunized against influenza annually is to be achieved. Close coordination between public health programs and clinical prevention efforts in primary care is necessary, but to be truly effective, these services must be culturally appropriate

Treatment of thoraco-lumbar curves in adolescent females affected by idiopathic scoliosis with a progressive action short brace (PASB): assessment of results according to the SRS committee on bracing and nonoperative management standardization criteria

<p>Abstract</p> <p>Background</p> <p>The effectiveness of conservative treatment of scoliosis is controversial. Some studies suggest that brace is effective in stopping curve progression, whilst others did not report such an effect.</p> <p>The purpose of the present study was to effectiveness of Progressive Action Short Brace (PASB) in the correction of thoraco-lumbar curves, in agreement with the Scoliosis Research Society (SRS) Committee on Bracing and Nonoperative Management Standardisation Criteria.</p> <p>Methods</p> <p>Fifty adolescent females (mean age 11.8 ± 0.5 years) with thoraco-lumbar curve and a pre-treatment Risser score ranging from 0 to 2 have been enrolled. The minimum duration of follow-up was 24 months (mean: 55.4 ± 44.5 months). Antero-posterior radiographs were used to estimate the curve magnitude (C_M) and the torsion of the apical vertebra (T_A) at 5 time points: beginning of treatment (t₁), one year after the beginning of treatment (t₂), intermediate time between t₁and t₄(t₃), end of weaning (t₄), 2-year minimum follow-up from t₄(t₅). Three situations were distinguished: curve correction, curve stabilisation and curve progression.</p> <p>The Kruskal Wallis and Spearman Rank Correlation tests have been used as statistical tests.</p> <p>Results</p> <p>C_Mmean value was 29,30 ± 5,16 SD at t₁and 14,67 ± 7,65 SD at t₅. T_Awas 12.70 ± 6,14 SD at t₁and 8,95 ± 5,82 at t₅. The variation between measures of Cobb and Perdriolle degrees at t_1,2,3,4,5and between C_Mt₅-t₁and T_At₅-t₁were significantly different.</p> <p>Curve correction was accomplished in 94% of patients, whereas a curve stabilisation was obtained in 6% of patients.</p> <p>Conclusion</p> <p>The PASB, due to its peculiar biomechanical action on vertebral modelling, is highly effective in correcting thoraco-lumbar curves.</p

The direct cost of "Thriasio" school screening program

<p>Abstract</p> <p>Background</p> <p>There is great diversity in the policies for scoliosis screening worldwide. The initial enthusiasm was succeeded by skepticism and the worth of screening programs has been challenged. The criticisms of school screening programs cite mainly the negative psychological impact on children and their families and the increased financial cost of visits and follow-up radiographs. The purpose of this report is to evaluate the direct cost of performing the school screening in a district hospital.</p> <p>Methods</p> <p>A cost analysis was performed for the estimation of the direct cost of the "Thriasio" school-screening program between January 2000 and May 2006. The analysis involved all the 6470 pupils aged 6–18 years old who were screened at schools for spinal deformities during this period. The factors which were taken into consideration in order to calculate the direct cost of the screening program were a) the number of the examiners b) the working hours, c) the examiners' salary, d) the cost of transportation and finally e) the cost of examination per child.</p> <p>Results</p> <p>During the examined period 20 examiners were involved in the program and worked for 1949 working hours. The hourly salary for the trainee doctors was 6.80 euro, for the Health Visitors 6.70 euro and for the Physiotherapists 5.50 euro in current prices. The cost of transportation was 32 euro per year. The direct cost for the examination of each child for the above studied period was calculated to be 2.04 euro.</p> <p>Conclusion</p> <p>The cost of our school-screening program is low. The present study provides a strong evidence for the continuation of the program when looking from a financial point of view.</p
