Background: Hepatitis B infection in injecting drug users is an important public health problem. Active immunization against hepatitis B is immunogenic and safe, but uptake rates in targeted vaccination programmes are low. This study was undertaken to identify factors associated with the uptake of hepatitis B vaccination in injecting drug users attending a needle exchange service.

Methods: A retrospective cross-sectional survey of case-note data of injecting drug users who had no markers of hepatitis B infection or immunity was undertaken within a drop-in needle exchange service for injecting drug users in a large urban area in England. A qualitative study using semi-structured interviews with needle exchange staff was also conducted.

Results: Of 207 injecting drug users, 180 (87 per cent) had been offered vaccine, 123 (59 per cent) accepted at least one dose and 55 (27 per cent) received three or more doses. Vaccine was less likely to be offered to those sharing injecting equipment or known to have hepatitis C. Needle sharing was also associated with failure to accept vaccine, as was increasing age and the length of contact with the service.

Conclusions: Those who are most at risk are least likely to be offered vaccine and accept it. This calls into doubt the effectiveness of hepatitis B vaccination strategies targeted at high-risk groups and adds weight to arguments for universal vaccination.

Background: The continuing identification, assessment and management of risks are key themes for clinical governance. These themes are being integrated into both primary and secondary care practice; however, integration into public health practice appears much slower. This paper describes the recent approach that we have taken in Sheffield, and proposes a model for public health departments to identify, assess and manage risks, which complements other risk management processes and is transferable to other settings. It assumes that public health practice is not a risk-free activity and holds that the process of identifying, assessing and managing risks is a key component to raising standards.

Methods: A number of risk 'management' models were reviewed and a primary care approach was applied to public health practice. A list of potential risks was identified using a number of methods including reflective practice, information from complaints and/or critical incidents. Risks were assessed by likelihood and impact, and were captured in a risk framework.

Results: By March 2002, 21 risks had been identified and characterized, and progress had been made to manage 11 of these risks.

Conclusion: This process, and the development of a risk framework, was useful in identifying a prioritized work programme to improve standards of public health practice in this department. This model can also be used not only for planning risk management activities, continual identification and assessment of risks but also to provide inspiration for other clinical governance activities including public health audit.

Reports produced in response to the need for health technology assessment (HTA) vary greatly in the methods they use, depending on the decision-maker's needs, the technology's characteristics and the resources available. HTA reports vary from the brief, such as 'vignettes' produced when a new technology emerges, to the exhaustive, such as 'Cochrane reviews' synthesising a mature evidence base. They may address a wide range of different questions. 'Classic HTAs', typically those reports prepared to support NICE appraisal decisions, seek to use scientifically rigorous methods to address a focused policy question. These are based on systematic reviews of the effectiveness evidence but this is often fed into economic models, in order to generate estimates of cost-effectiveness. Future developments in HTA responses will reflect both the embedding of systematic methods and a growing responsiveness to customer needs.

Background: Evidence from outside the United Kingdom points to several socio-demographic factors associated with late initiation of antenatal care or fewer antenatal visits, but it is not clear how generalizable these studies are to the UK context. This systematic review addresses the question of whether there are social or ethnic inequalities in attendance for antenatal care in the United Kingdom.

Methods: We identified and reviewed UK studies assessing attendance for antenatal care according to any measure of social class, social deprivation or ethnicity. A wide range of electronic databases was searched for published and unpublished studies. Further studies were identified from reference lists, citation searches and key organizations.

Results: From over 1300 identified papers, 20 were potentially relevant. Nine were included in the review. Most studies were of poor quality, with only one study controlling for the effect of potential confounders such as age, parity and clinical risk factors. All but one were based on data collected around 20 years ago. Three of the five studies looking at antenatal attendance and social class found that women from manual classes were more likely to book late for antenatal care and/or make fewer antenatal visits than other women. All four studies reporting on antenatal attendance and ethnicity found that women of Asian origin were more likely to book late for antenatal care than white British women.

Conclusions: There is little good quality evidence on social and ethnic inequalities in attendance for antenatal care in the United Kingdom. Recommendations for further research are suggested.

Background: Little is known about the utilization of NHS Direct by disadvantaged groups, in spite of the service aiming to be 'accessible to all'. This study investigates the relationship between use of NHS Direct and deprivation in one predominantly disadvantaged area.

Methods: Ward-level call rates to NHS Direct South East London over a 6 month period were calculated using postcode data. Jarman and Townsend scores were used as a proxy of deprivation in each ward. We performed negative binomial regression to investigate the relationship between deprivation score and rate of calls to NHS Direct.

Results: There was a significant, non-linear (quadratic) effect of deprivation score on call rates; call rates were lower in both the most affluent and most deprived wards.

Conclusion: Calls to NHS Direct rise with increasing deprivation until, at extreme levels of deprivation, they subsequently decline. This challenges assumptions that NHS Direct is not utilized in deprived areas.

Background: Compared with other developed countries, the United Kingdom has exhibited less of an increase in life expectancy over the past 30 years.

Methods: We compared the chronological changes in the age-adjusted mortality rates (AMRs) from all causes or major causes, and in life expectancy in the United Kingdom and Japan between 1970 and 1997.

Results: In both 1970 and 1997 the AMRs for most major causes were higher in the United Kingdom than in Japan; the difference in the AMR between countries was smaller in 1970 than in 1997. The difference in the AMR from all causes between the United Kingdom and Japan in 1997 was mainly due to differences in the AMR for heart diseases. The trend for an increasing difference over time between the United Kingdom and Japan in the AMR from all causes was due to the decreased rate of AMR from heart diseases from 1970 to 1997 in the United Kingdom being lower than those from cerebrovascular diseases in same period in Japan.

Conclusions: These data suggest that mortality rates could be reduced by a change in focus of the National Health Service toward an emphasis on primary rather than secondary prevention and associated clinical interventions. The greatest priority should be placed on reducing the incidence of heart disease by aggressively improving primary prevention.

Background: A significant proportion of women who are vulnerable to postnatal depression refuse to engage in treatment programmes. Little is known about them, other than some general demographic characteristics. In particular, their access to health care and their own and their infants' health outcomes are uncharted.

Methods: We conducted a nested cohort case-control study, using data from computerized health systems, and general practitioner (GP) and maternity records, to identify the characteristics, health service contacts, and maternal and infant health outcomes for primiparous antenatal clinic attenders at high risk for postnatal depression who either refused (self-exclusion group) or else agreed (take-up group) to receive additional Health Visiting support in pregnancy and the first 2 months postpartum.

Results: Women excluding themselves from Health Visitor support were younger and less highly educated than women willing to take up the support. They were less likely to attend midwifery, GP and routine Health Visitor appointments, but were more likely to book in late and to attend accident and emergency department (A&E). Their infants had poorer outcome in terms of gestation, birthweight and breastfeeding. Differences between the groups still obtained when age and education were taken into account for midwifery contacts, A&E attendance and gestation; the difference in the initiation of breast feeding was attenuated, but not wholly explained, by age and education.

Conclusion: A subgroup of psychologically vulnerable child-bearing women are at particular risk for poor access to health care and adverse infant outcome. Barriers to take-up of services need to be understood in order better to deliver care.

Background: The aim of the study was to provide a critical and comprehensive overview of the published peer-reviewed evidence relating to community pharmacy-based activity in the reduction of risk behaviours and risk factors for coronary heart disease (CHD).

Method: Electronic databases were searched from 1 January 1990 to 1 February 2001. Hand searches for the same period were undertaken of specific journals and proceedings of peer-reviewed conference abstracts. Data abstracted from publications included: participants/setting; study designs intervention including training); outcome measures; key findings.

Results: Four randomized controlled trials (RCTs) were identified, two in smoking cessation and two in lipid management. All met review criteria and were included. Two (RCTs) involving 976 subjects and three non-randomized experimental studies were identified that evaluated the effectiveness of community pharmacy advice in smoking cessation. Two controlled trials and one before-and-after study investigated the effect of training on pharmacists' smoking cessation advice. One attitudinal survey collected data on reactive and proactive smoking cessation advice-giving by community pharmacists. Two RCTs involving 642 subjects, and two observational studies were identified for community pharmacy-based lipid management. The published studies provided evidence of clinical and cost-effectiveness of community pharmacy services from UK RCTs in smoking cessation, and from US and Canadian RCTs in lipid management in the prevention of heart disease. Although the role of the community pharmacy in disease detection and case finding has been widely discussed, only a small number of studies was found. The findings indicated that further investigation is warranted in these areas.

Conclusion: The peer-reviewed literature demonstrates the contribution of community pharmacy-based services to the reduction of risk behaviours and risk factors for CHD. The evidence supports the wider provision of smoking cessation and lipid management through community pharmacies. Health commissioners and planners can use the findings of this review to incorporate community pharmacy based health development activities into local health services. Further research is needed into the contribution of community pharmacy to disease detection and case finding as part of local public health strategies.

Health technology assessment (HTA)--the provision to decision makers of information on the value of treatments and tests--has come of age in the last two decades. But it has deep roots in health care, with notable landmarks in (1) the mid eighteenth-century development of empiricism, (2) the twentieth century interest in outcomes and variation in health care, and (3) the pioneering work of Archie Cochrane and others in the 1970s. Three main forces have driven the recent developments of HTA: a combination of concerns about the adoption of unproven technologies, rising costs, and an inexorable rise in consumer expectations. The HTA response, essentially initiatives supporting the provision of reliable synthesised research information on the effects and costs of health technologies, have been well supported in the United Kingdom and internationally. We can be sure that HTA is here to stay.
