Implementing Evidence-Based Practice in Health Care

This article summarizes recent research on the effectiveness of efforts to implement evidence-based health care. The authors conclude that the evidence in support of single interventions being effective in bringing about practitioner change is weak at best. The authors give examples and evaluative comments on more complex organizational and systemic interventions that are aimed at changing clinical practice, and discuss some of the barriers to their application.     

The employability of new graduates: a study of differences between UK universities

The non-stationarity tests of Phillips-Perron (1988) (PP tests) suggest that Australian macroeconomic output possesses a stochastic rather than a deterministic log-linear trend. Kwiatkowski et al. (1991) argue that such tests have low power and propose the KPSS test, in which the null is stationary. However, the KPSS test results reinforce the PP findings for Australia. Cochrane (1988) variance ratio (VR) tests further suggest that there may be a very strong random-walk component in the Australian business cycle. Rappoport and Reichlin (1989), however, argue that all such tests are biased in favour of the stochastic trend alternative if there are trend breaks in the data. Following up on this point, the paper finds that, in Australia's case, the stochastic trend alternative is statistically dominated when the data are allowed to be characterized by a probabilistic, regime-switching, segmented trend specification. Therefore, to the extent that real business-cycle theories of the business cycle gain support from stochastic trends in real output, this latter piece of Australian evidence does not strengthen their case.     

Punishment in a Regulatory Setting: Experimental Evidence from the VCM

To analyze the effectiveness of punishment in inducing regulatory compliance, we modify a standard public goods experiment to include a financial penalty for free riding. The design allows us to vary both punishment probability and severity. We introduce the punishment mechanism in both a one-time and a repeated treatment and find that compliance (contributing to the public good) is increasing in expected punishment cost in both treatments. We also find that punishment severity has a larger effect on behavior than punishment probability. In the repeated treatment, we find that past punishment has a negative rather than positive effect on compliance.     

Occupational Change and Mobility Among Employed and Unemployed Job Seekers

We use data from the Labour Force Survey to show that employed and unemployed job seekers in Great Britain originate from different occupations and find jobs in different occupations. We find substantial differences in occupational mobility between job seekers: employed job seekers are most likely to move to occupations paying higher average wages relative to their previous occupation, while unemployed job seekers are most likely to move to lower paying occupations. Employed and unemployed job seekers exhibit different patterns of occupational mobility and, therefore, do not accept the same types of jobs.     

On measuring the utilization rate of employed labour

This paper deals with the factors that influence plans to retire from the labour force. We use a theoretical model to explain the empirical findings from a bivariate probit model relating economic, demographic, and social characteristics to retirement plans for over 7000 women and men between the ages of 40 and 64. The results of the analysis concerning retirement intentions suggest that personal, economic and household characteristics are more important determinants of retirement plans for women than men.     

Comparative effectiveness of standard endotracheal tubes vs. endotracheal tubes with continuous subglottic suctioning on ventilator-associated pneumonia rates

Ventilator-associated pneumonia (VAP) accounts for the majority of nosocomial pneumonias, which may increase intensive care and prolonged hospital stays. Endotracheal tubes allowing continuous subglottic suctioning may reduce VAP; however, they are more expensive than standard endotracheal tubes not allowing continuous suctioning. he objective of this study was to measure the comparative costs associated with continuous subglottic suctioning endotracheal tubes (CSS-ETT) versus standard endotracheal tubes (S-ETT) among intubated patients and whether cost differential is offset by the occurrence of VAP in patients receiving either type of intubation. A retrospective chart review was conducted for 154 intubated adult patients (77 = S-ETT; 77 = CSS-ETT). The S-ETT group had one case of VAP; the CSS-ETT group had none. The mean total hospital charges were higher for the S-ETT group ($103,600; CSS-ETT= $88,500) (p = 0.3). Although the average number of intubation days and ICU days were greater for the CSS-ETT group, there were no cases of VAP compared to the S-ETT group. ased upon the one S-ETT VAP case and the VAP attributable costs, it is cost effective to use the CSS-ETT.     

Pre‐sale information and hammer prices for Australian Indigenous art

Using sales data from 1987–2011 we investigate the role that pre‐sale price information plays in determining hammer prices for Australian Indigenous artworks. Importantly, we control for the degree of market concentration as this might influence buyers’ perceptions of fairness in relation to price estimates which are provided by auction houses. Auction houses therefore act as important intermediaries between art sellers and art buyers. The results suggest that pre‐sale estimates and market concentration have a differential impact on hammer prices, depending on the point in the conditional realised price distribution under examination.
