Public Health Benefits (public + health_benefit)
Selected AbstractsContemporary issues in dental education in AustraliaAUSTRALIAN DENTAL JOURNAL, Issue 1 2010TJ Freer Abstract Australia has witnessed a proliferation of dental workforce training opportunities over the last 15 years, including dentists, dental therapists, dental hygienists and prosthetists. The reasons for this have not been examined critically. Universities have welcomed the opportunities to increase the student base but do not seem to have examined the advisability of continued expansion or its impact on the delivery and costs of health services. Nor have they enquired expressly whether they have any responsibility in these matters. Public health benefits should constitute a significant element of curriculum design. There seems to have been a general acceptance of the premise that more is necessarily better. Ironically, these developments have occurred in the face of significant recurrent cost increments and serious academic staff shortages. The schools have responded with alterations to curriculum content. Student cohort composition, course structures, educational focus, postgraduate training and research have been affected. The primary purpose of this review is to highlight the issues which currently drive workforce training and curriculum content and to suggest that some current practices should be re-examined as a starting point for setting defined common objectives within the Australian dental educational spectrum. Salient issues which require examination include course standards and accreditation, workforce mix, dental health demands, public service obligations and staffing profiles. [source] A randomized controlled trial of an internet-based intervention for alcohol abusersADDICTION, Issue 12 2009John A. Cunningham ABSTRACT Objective Misuse of alcohol imposes a major public health cost, yet few problem drinkers are willing to access in-person services for alcohol abuse. The development of brief, easily accessible ways to help problem drinkers who are unwilling or unable to seek traditional treatment services could therefore have significant public health benefit. The objective of this project is to conduct a randomized controlled evaluation of the internet-based Check Your Drinking (CYD) screener ( http://www.CheckYourDrinking.net). Method Participants (n = 185) recruited through a general telephone population survey were assigned randomly to receive access to the CYD, or to a no-intervention control group. Results Follow-up rates were excellent (92%). Problem drinkers provided access to the CYD displayed a six to seven drinks reduction in their weekly alcohol consumption (a 30% reduction in typical weekly drinking) at both the 3- and 6-month follow-ups compared to a one drink per week reduction among control group respondents. Conclusions The CYD is one of a growing number of internet-based interventions with research evidence supporting its efficacy to reduce alcohol consumption. The internet could increase the range of help-seeking options available because it takes treatment to the problem drinker rather than making the problem drinker come to treatment. [source] A Generalized Estimator of the Attributable Benefit of an Optimal Treatment RegimeBIOMETRICS, Issue 2 2010Jason Brinkley Summary For many diseases where there are several treatment options often there is no consensus on the best treatment to give individual patients. In such cases, it may be necessary to define a strategy for treatment assignment; that is, an algorithm that dictates the treatment an individual should receive based on their measured characteristics. Such a strategy or algorithm is also referred to as a treatment regime. The optimal treatment regime is the strategy that would provide the most public health benefit by minimizing as many poor outcomes as possible. Using a measure that is a generalization of attributable risk (AR) and notions of potential outcomes, we derive an estimator for the proportion of events that could have been prevented had the optimal treatment regime been implemented. Traditional AR studies look at the added risk that can be attributed to exposure of some contaminant; here we will instead study the benefit that can be attributed to using the optimal treatment strategy. We will show how regression models can be used to estimate the optimal treatment strategy and the attributable benefit of that strategy. We also derive the large sample properties of this estimator. As a motivating example, we will apply our methods to an observational study of 3856 patients treated at the Duke University Medical Center with prior coronary artery bypass graft surgery and further heart-related problems requiring a catheterization. The patients may be treated with either medical therapy alone or a combination of medical therapy and percutaneous coronary intervention without a general consensus on which is the best treatment for individual patients. [source] Epidemiology of invasive and other pneumococcal disease in children in England and Wales 1996,1998ACTA PAEDIATRICA, Issue 2000E Miller The results of enhanced national surveillance of pneumococcal disease in children <15y of age in England and Wales are reported for the period 1996,1998. Of the 1985 cases of laboratory-confirmed invasive disease (annual incidence 6.6 per 100000 overall and 39.7 per 100000 in infants <1 y of age), 485 (24%) were meningitis (annual incidence of 1.6 per 100000 overall and 15.7 per 100000 in infants <1 y of age). Fifty-nine deaths in children with invasive disease were identified-3% of the total reports. Thirty-one different serogroups/types were identified, with organisms in the 7-valent conjugate vaccine responsible for 69% of the infections in children <5 y of age; this rose to 77% and 82%, respectively, for the 9-and 11-valent vaccines. Resistance to penicillin varied from 2.3% to 6.2% in different years, but erythromycin resistance remained constant at 17%. The vast majority of resistant isolates were in vaccine serotype/groups. Computerized hospital admission records for all children <15 y of age with a discharge diagnosis code indicating probable pneumococcal disease were also analysed for 1997. The annual incidence for cases with a code specifically mentioning S. pneumoniae was 9.9 per 100000 compared with 71.2 per 100000 for lobar pneumonia; the mean duration of stay for both was < 1 wk. The incidence of admission for pneumococcal meningitis (1.9 overall and 19.6 for infants < 1 y of age) was similar to that derived from laboratory reports and resulted in an average duration of stay of 2 wk. Conclusion: This surveillance has confirmed the substantial burden of morbidity attributable to pneumococcal disease in British children and the potential public health benefits that could be achieved by the use of pneumococcal conjugate vaccines. [source] What are the policy lessons of National Alcohol Prohibition in the United States, 1920,1933?ADDICTION, Issue 7 2010Wayne Hall ABSTRACT National alcohol prohibition in the United States between 1920 and 1933 is believed widely to have been a misguided and failed social experiment that made alcohol problems worse by encouraging drinkers to switch to spirits and created a large black market for alcohol supplied by organized crime. The standard view of alcohol prohibition provides policy lessons that are invoked routinely in policy debates about alcohol and other drugs. The alcohol industry invokes it routinely when resisting proposals to reduce the availability of alcohol, increase its price or regulate alcohol advertising and promotion. Advocates of cannabis law reform invoke it frequently in support of their cause. This paper aims: (i) to provide an account of alcohol prohibition that is more accurate than the standard account because it is informed by historical and econometric analyses; (ii) to describe the policy debates in the 1920s and 1930s about the effectiveness of national prohibition; and (iii) to reflect on any relevance that the US experience with alcohol prohibition has for contemporary policies towards alcohol. It is incorrect to claim that the US experience of National Prohibition indicates that prohibition as a means of regulating alcohol is always doomed to failure. Subsequent experience shows that partial prohibitions can produce substantial public health benefits at an acceptable social cost, in the absence of substantial enforcement. [source] Price increase causes fewer sales of factory-made cigarettes and higher sales of cheaper loose tobacco in GermanyHEALTH ECONOMICS, Issue 6 2008Reiner Hanewinkel Abstract Aim of this study is the analysis of the price responsiveness of demand for cigarettes and loose tobacco in Germany over the period 1991,2006. In this period the average consumption of all kinds of cigarettes per capita (German population , 15 years) declined from 634 pieces/quarter to 457pieces/quarter (,28%). Consumption of factory-made cigarettes decreased from about 545 pieces/quarter to 330 pieces/quarter in 2006 (,39%). In the same time consumption of self-made cigarettes increased from 89 pieces/quarter to 127 pieces/quarter (+42%). A one Euro Cent increase in price is associated with 28 cigarettes of all kinds consumed less per quarter. Data indicate that the different types of cigarettes are substitutes, e.g. there is evidence for a positive relationship between the price of factory-made cigarettes and the consumption of hand-made cigarettes. Thus, the increase in such consumption is rather driven by a positive cross-price effect of 17.01. Data indicate additionally an overall decrease in the cigarette consumption and a partial switch to cheaper loose tobacco. The availability of low-taxed loose tobacco may undermine the public health benefits of higher cigarette prices. Price differentials between tobacco products should be reduced in order to maximize the public health benefits of high cigarette prices. Copyright © 2007 John Wiley & Sons, Ltd. [source] Resistance and Agility Training Reduce Fall Risk in Women Aged 75 to 85 with Low Bone Mass: A 6-Month Randomized, Controlled Trial,JOURNAL OF AMERICAN GERIATRICS SOCIETY, Issue 5 2004Teresa Liu-Ambrose PhD Objectives: To compare the effectiveness of group resistance and agility-training programs in reducing fall risk in community-dwelling older women with low bone mass. Design: A randomized, controlled, single-blind 25-week prospective study with assessments at baseline, midpoint, and trial completion. Setting: Community center. Participants: Community-dwelling women aged 75 to 85 with low bone mass. Intervention: Participants were randomly assigned to one of three groups: resistance training (n=32), agility training (n=34), and stretching (sham) exercises (n=32). The exercise classes for each study arm were held twice weekly. Measurements: The primary outcome measure was fall risk (derived from weighted scores from tests of postural sway, reaction time, strength, proprioception, and vision), as measured using a Physiological Profile Assessment (PPA). Secondary outcome measures were ankle dorsiflexion strength, foot reaction time, and Community Balance and Mobility Scale score. Results: Attendance at the exercise sessions for all three groups was excellent: resistance training (85.4%), agility training (87.3%), and stretching program (78.8%). At the end of the trial, PPA fall-risk scores were reduced by 57.3% and 47.5% in the resistance and agility-training groups, respectively, but by only 20.2% in the stretching group. In the resistance and agility groups, the reduction in fall risk was mediated primarily by improved postural stability, where sway was reduced by 30.6% and 29.2%, respectively. There were no significant differences between the groups for the secondary outcomes measures. Within the resistance-training group, reductions in sway were significantly associated with improved strength, as assessed using increased squat load used in the exercise sessions. Conclusion: These findings support the implementation of community-based resistance and agility-training programs to reduce fall risk in older women with low bone mass. Such programs may have particular public health benefits because it has been shown that this group is at increased risk of falling and sustaining fall-related fractures.
