    Objective: The purpose of this study was to report the “Outcome Reporting in Brief Intervention Trials: Alcohol” (ORBITAL) recommended core outcome set (COS) to improve efficacy and effectiveness trials/evaluations for alcohol brief interventions (ABIs). Method: A systematic review identified 2,641 outcomes in 401 ABI articles measured by 1,560 different approaches. These outcomes were classified into outcome categories, and 150 participants from 19 countries participated in a two-round e-Delphi outcome prioritization exercise. This process prioritized 15 of 93 outcome categories for discussion at a consensus meeting of key stakeholders to decide the COS. A psychometric evaluation determined how to measure the outcomes. Results: Ten outcomes were voted into the COS at the consensus meeting: (a) typical frequency, (b) typical quantity, (c) frequency of heavy episodic drinking, (d) combined consumption measure summarizing alcohol use, (e) hazardous or harmful drinking (average consumption), (f) standard drinks consumed in the past week (recent, current consumption), (g) alcohol-related consequences, (h) alcohol-related injury, (i) use of emergency health care services (impact of alcohol use), and (j) quality of life. Conclusions: The ORBITAL COS is an international consensus standard for future ABI trials and evaluations. It can improve the synthesis of new findings, reduce redundant/selective reporting (i.e., reporting only some, usually significant outcomes), improve between-study comparisons, and enhance the relevance of trial and evaluation findings to decision makers. The COS is the recommended minimum and does not exclude other, additional outcomes

    Competition and substitution between public transport modes

    The management and understanding of modal split between public transport (PT) modes is of interest for numerous reasons. It may, for example, be desirable to stimulate passengers to switch from crowded buses and over to higher capacity rail. This requires a good understanding of drivers of transit modal substitution. The evidence put forward in this paper is based on more than 150 empirically estimated cross elasticities between PT modes from over 20 sources collected from Australia, Europe and USA. These sources include scientifically published evidence as well as grey literature. This evidence is coded into a database from which our paper presents and analyses the available cross-PT-modal demand relations. We focus on evidence for how fares, travel time and service intervals on PT ‘mode A’ affect the demand for PT ‘mode B’. Despite generally low levels of substitution between PT modes, passengers are particularly sensitive to in-vehicle, access/egress and waiting time in choosing PT mode and less so for fare variations. In general, rail demand is less sensitive to changes in bus than bus demand is to changes in rail. We also find that peak-hour demand more markedly switches between PT modes than off-peak demand does

    What Factors Affect Cross-Modal Substitution - Evidences from the Oslo Area

    The vast majority of studies on urban travel demand focus on the effect on the demand of one travel mode given a change in the characteristics of that same transport mode, for example, own-elasticities. comparatively little is known about cross-elasticities of demand. In particular, there is a need for a better understanding of the underlying mechanisms of modal substitution, that is a better understanding of cross-modal diversion factors (Dfs) defined as the proportion of people who leave mode a and switch to mode b. The purpose of this article is to investigate what factors explain variations in Dfs across transport modes, submarkets and policy measures. using a recently developed empirical travel mode choice model for the Oslo area, we simulate over 10,000 different Dfs by systematically changing the underlying transport modes, submarkets and policies (size, direction and type of change). With descriptive statistics, we show how the Dfs vary on a general level. most results are immediately intuitive, for example that car drivers mostly substitute to walk for short-distance trips but that those Dfs diminish rapidly with increasing distance. Interestingly, we find rather high Dfs across different forms of public transportation. With successive regression analyses we show that the number of available alternatives and relative market shares significantly affect Dfs

    Prescribing active transport as a planetary health intervention – benefits, challenges and recommendations

    A high proportion of people are insufficiently physically active. The reasons for this are complex and in part relate to social determinants of health, lifestyle choices, and deleterious environmental conditions like climate change, loss of green and outdoor environments and a concomitant loss of biodiversity. Physiotherapists, and other health professionals, may have a positive impact on these global issues, through the encouragement of active transport, and advocacy to reduce barriers to its uptake and optimize exposure to health-giving outdoor spaces. In this paper, we demonstrate how physiotherapists can promote active transport as a planetary health intervention, and provide insight into the benefits and challenges of this planetary health intervention, with direct implications to physiotherapy practice

    Implications of cost recovery

    No full text
    Under some circumstances, the marginal cost approach to infrastructure pricing leads to problems with cost recovery; a pricing policy which ensures that existing assets are efficiently used may not deliver revenue to pay for the costs for maintenance of existing, nor indeed for construction of new infrastructure. For different reasons governments may find this inappropriate and rather want to complement the marginal-cost-pricing principle with a requirement for a sector of the economy to break even. Efficiency would then be jeopardised. The idea behind work package 2 is to establish the micro-aspects of requirements to recover costs over and above marginal costs. This is done for all modes of transport. More precisely, the objective of this report is to establish some core features of how each mode of transport is organised, to describe the implications of cost recovery requirements for each mode and to analyse different mechanisms which would ascertain that each mode covers a larger share of its own costs.CATRIN - Cost allocation of transport infrastructure cos
