"Tell us something new!" : the response of planning and transport professionals to public health guidance on the built environment and physical activity

A large proportion of non-communicable disease can be attributed to modifiable risk factors such as poor nutrition and physical inactivity. We present data on planning and transport practitioners' perceptions and responses to government public health guidance aimed at modifying environmental factors to promote physical activity. This study was informed by questions on the role of evidence-based guidance, the views of professionals towards the guidance, the links between guidance and existing legislation and policy and the practicality of guidelines. A key informant 'snowball' sampling technique was used to recruit participants from the main professional planning organisations across England. Seventy-six people were interviewed in eight focus groups. We found that evidence-based public health guidance is a new voice in urban and town planning, although much of the advice is already reflected by the 'accepted wisdom' of these professions. Evidence-based health guidance could be a powerful driver affecting planning practice, but other legislated planning guidance may take priority for planning and transport professionals.

What determines the size of occupational health services in UK universities?

Background There is wide, largely unexplained, variation in occupational health (OH) provision between UK employers.

Aim To explain the variation in OH provision across the UK university sector.

Methods Analyses of data from a survey of university OH services and from the Higher Education Statistics Agency. The outcome variable was clinical (doctor + nurse) staffing of the university's OH service. The explanatory variables examined were university size, income, research activity score and presence or absence of academic disciplines categorized by an expert panel as requiring a high level of OH provision.

Results All 117 UK universities were included and 93 (79%) responded; with exclusions and incomplete data, between 80 and 89 were included in analyses. There was wide variation in clinical OH staffing (range 0–8.4 full-time equivalents). Number of university staff explained 34% of the variation in OH staffing. After adjusting for other factors, neither the research activity nor the presence of high-needs disciplines appeared to be factors currently used by employers to determine their investment in OH.

Conclusions Government or other guidelines for university employers should take organizational size into account. Employers may need guidance on how to provide OH services proportionate to specific occupational hazards or other OH needs.

Occupational health services in higher education : third annual report

Occupational health services can make a valuable contribution to the performance of HEIs, yet a pilot study in 1999 suggested that occupational health provision in the HE sector lags behind other sectors, with some noticeable gaps. This project will:

* survey all UK HEIs to establish a baseline and identify examples of good practice in occupational health provision
* disseminate benchmarking information and case studies
* establish a collaborative network to encourage the development, sharing and implementation of recognised good practice and ensure the sustainability of improvements resulting from the project
* evaluate the outcomes of the above work.

Occupational health services in higher education : second annual report : summary

The second of three surveys of occupational health provision in UK higher education institutions was carried out in March 2003.

Information was collected on occupational health provision arrangements for all 193 members of UUK, other HEIs funded by HEFCE, constituent parts of the University of London and the University of Wales, and degree awarding bodies in the UK. There was a wide variety of arrangements. Thirty-eight percent had in-house services, 33% contracted with external providers for occupational health services, 13% made use of a local general practice or student health service, 6% had other or ad hoc arrangements and 9% had no occupational health service.

Modelling the public health consequences of cannabis use in Australia

Aims: To detail and validate a simulation model that describes the dynamics of cannabis use, including its probable causal relationships with schizophrenia, road traffic accidents (RTA) and heroin/poly-drug use (HPU).

Methods: A Markov model with 17 health-states was constructed. Annual cycles were used to simulate the initiation of cannabis use, progression in use, reduction and complete remission. The probabilities of transition between health-states were derived from observational data. Following 10-year-old Australian children for 90 years, the model estimated age-specific prevalence for cannabis use. By applying the relative risks according to the extent of cannabis use, the age-specific prevalence of schizophrenia and HPU, and the annual RTA incidence and fatality rate were also estimated. Predictive validity of the model was tested by comparing modelled outputs with data from other credible sources. Sensitivity and scenario analyses were conducted to evaluate technical validity and face validity.

Results: The estimated cannabis use prevalence in individuals aged 10-65 years was 12.2% which comprised 27.4% weekly and 18.0% daily users. The modelled prevalence and age profile were comparable to the reported cross-sectional data. The model also provided good approximations to the prevalence of schizophrenia (Modelled: 4.75/1,000 persons vs Observed: 4.6/1,000 persons), HPU (3.2/1,000 vs 3.1/1,000) and the RTA fatality rate (8.1 per 100,000 vs 8.2 per 100,000). Sensitivity analyses and scenario analysis provided expected and explainable trends.

Conclusions: The validated model provides a valuable tool to assess the likely effectiveness and cost-effectiveness of interventions designed to affect patterns of cannabis use. It can be updated as new data becomes available and/or applied to other countries.

Media reports of heroin overdose spates: public health messages, moral panics or risk advertisements?

This article reports on an investigation of the public health utility of media messages concerning spates (temporal clusters) of heroin-related overdose (HOD) from the perspective of some injecting drug users (IDUs). In-depth qualitative interviews were carried out with a convenience sample of 60 IDUs, in the setting of two Needle and Syringe Programs in an Australian regional city (Geelong) between April and May 2000. Very few interviewees reported that they had personally experienced a spate of overdoses. None of the interviewees reported communicating the existence of a killer batch to other IDUs. No interviewees reported having changed either their injecting practices or the amount of heroin they used following such a media alert. Indeed, a substantial minority of the interviewees reported seeking out these stronger batches and participant narratives illustrate that, for a substantial group of interviewees, the media reporting of a hypothetical 'killer batch' of heroin may have implications for their drug-seeking and health-related behaviour. It was found that the accuracy of information available to IDUs is mixed and that the flow of information within this social network was slow. Findings demonstrate that media reporting of killer batches of heroin has little value as a public health strategy and provide an example of how some activities that are proposed as public health measures may in fact have the opposite effect.

Analysis of outsourcing in the Victorian public health sector

The research has uncovered a major reason for outsourcing in this sector as a desire to improve middle management, specifically their skill levels and familiarity with new operating procedures. Outsourcing negative outcomes were the result of decision-makers not considering the length of relationships between parties and the lack of information available to monitor quality and other contractual terms. Outsourcing has been performed for various reasons, but rarely have decision-makers considered the full range of factors that may potentially affect the optimal nature of the decision, or the organisational characteristics of their workplaces.

Discursive recontextualization in a public health setting

The authors discuss discursive recontextualization as a process of discursive change in which stable referents may be recombined. As such, discursive recontextualization recognizes the interplay of both stability and instability without necessarily privileging the latter. Drawing on intertextual document analysis of a series of public reports published in the wake of a major health policy initiative in Victoria, Australia— Health to 2050—the authors identify a discursive pattern in which descriptions of a disaggregation from large Health Care Networks to smaller Metropolitan Health Services echo those of an earlier aggregation of individual hospitals into the Health Care Networks. The authors suggest that future research into discourse and organizational change will benefit from greater attention to stabilization and such recontextualization as well as to fluidity and instability. They examine implications for change agents and for researchers in the field.
