Impact of paracetamol pack size restrictions on poisoning from paracetamol in England and Wales: an observational study.

BACKGROUND: About 500 drug poisoning deaths involving paracetamol (acetaminophen) occur every year in England and Wales. To reduce the number of deaths, regulations were introduced in 1998 to restrict the sale of paracetamol. In this paper, we evaluate the impact of these regulations. METHODS: Mortality data for England and Wales were provided by the Office for National Statistics. Deaths were defined as due to compound paracetamol (paracetamol in combination with another analgesic, a low dose opioid or other ingredients) or paracetamol only, with or without alcohol or other drugs. The Department of Health provided data on all hospital admissions with a primary diagnosis of paracetamol poisoning. RESULTS: Mortality rates for paracetamol only were similar for males and females, and decreased from about 4.5 to 2.8 per million between 1997 and 1999 and again from about 3.1 to 2.2 per million between 2001 and 2002. These falls may be attributable to random variation in the rates. Deaths involving compound paracetamol, which were not subject to the 1998 regulations, remained relatively constant over the study period. There was evidence of a decreasing trend in paracetamol only mortality rates and this followed overall trends for other drug poisoning excluding opioids and drugs of misuse. Hospital admissions due to paracetamol poisoning increased from about 27 000 to 33 000 between 1995/1996 and 1997/1998 and then decreased to 25 000 in 2001/2002. There were almost 50 per cent more admissions for females than males, with the highest admission rates amongst females aged 15-24 years old. CONCLUSIONS: Between 1993 and 2002, mortality rates and hospital admissions due to paracetamol poisoning declined. However, the contribution of the 1998 regulations to this decline is not clear. Paracetamol poisoning continues to be an important public health issue in England and Wales and represents significant workload for the NHS in England.

Prevalent diagnosed HIV in England, Wales and Northern Ireland: adjusted totals 1996 to 2001 and extrapolations to 2004.

OBJECTIVE: To predict trends in diagnosed HIV prevalence by extrapolation to 2004 using data from the annual surveys of individuals receiving HIV-related care in England, Wales and Northern Ireland from 1996 to 2001. METHODS: Data from the annual surveys of prevalent HIV infections diagnosed (SOPHID) were adjusted for under-reporting and non-attendance and separately extrapolated for infections acquired homosexually, heterosexually and by other routes. The data were extrapolated using negative binomial and linear regression models based on the 1996 to 2001 annual surveys. RESULTS: The negative binomial model predicted an increase of 56% in diagnosed HIV prevalence in England, Wales and Northern Ireland between 2001 and 2004. The linear model predicted an increase of 25% for the same time period. The predicted increases are mostly driven by the large rise in the number of new diagnoses, in particular in individuals infected heterosexually. CONCLUSION: Increases in HIV prevalence in England, Wales and Northern Ireland have diverged from a linear trend. Negative binomial modelling of the data predicts that large rises in prevalence will continue during the early 2000s.

Surveillance of HIV-1 subtypes among heterosexuals in England and Wales, 1997-2000.

The molecular diversity and demographic characteristics among 976 anti-HIV-1-positive heterosexuals attending 15 sexually transmitted infection (STI) clinics participating in an unlinked anonymous HIV prevalence serosurvey in England and Wales during 1997-2000 were investigated. Subtypes were assigned by heteroduplex mobility assay or sequencing of the p17/p24 region of gag and the V3/V4 region of env and by sequencing of the protease gene. Overall, there was no significant change in the subtype distribution, with subtype C accounting for the majority (32%) of subtyped infections. Subtypes B (29%), A (12%), circulating recombinant forms (CRFs, 9%), unique recombinant forms (URFs, 8%), and subtypes D-H (8%) were also detected. Thirty-nine percent of infections in men were with subtype B, whereas subtype C was most common (38%) in women. Logistic regression analyses showed the relative risk (RR) of infection with a non-B subtype, compared with subtype B, to be greater in African-born individuals (RR = 28.9, P < 0.01), among newly diagnosed infections (RR = 3.4, P < 0.01), and in women (RR = 2.4, P < 0.01). These findings indicate a high level of genetic diversity among HIV-infected heterosexual STI clinic attendees in England and Wales. Recently, subtype C has become most prevalent, particularly in younger age groups, suggesting recent acquisition of this viral strain. The high proportion of non-B, CRF, and URF infections among UK-born individuals is consistent with mixing between migrants and UK-born individuals in England and Wales. As migration patterns change, continued monitoring of HIV genetic diversity will aid understanding of transmission patterns.

Epidemiology of severe sepsis occurring in the first 24 hrs in intensive care units in England, Wales, and Northern Ireland.

OBJECTIVE: To investigate the numbers, clinical characteristics, resource use, and outcomes of admissions who met precise clinical and physiologic criteria for severe sepsis (as defined in the PROWESS trial) in the first 24 hrs in the intensive care unit. DESIGN: Observational cohort study, with retrospective analysis of prospectively collected data. SETTING: Ninety-one adult general intensive care units in England, Wales, and Northern Ireland between 1995 and 2000. PATIENTS: Patients were 56,673 adult admissions. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: We found that 27.1% of adult intensive care unit admissions met severe sepsis criteria in the first 24 hrs in the intensive care unit. Most were nonsurgical (67%), and the most common organ system dysfunctions were seen in the cardiovascular (88%) and respiratory (81%) systems. Modeling the data for England and Wales for 1997 suggested that 51 (95% confidence interval, 46-58) per 100,000 population per year were admitted to intensive care units and met severe sepsis criteria in the first 24 hrs.Of the intensive care unit admissions who met severe sepsis criteria in the first 24 hrs, 35% died before intensive care unit discharge and 47% died during their hospital stay. Hospital mortality rate ranged from 17% in the 16-19 age group to 64% in those >85 yrs. In England and Wales in 1997, an estimated 24 (95% confidence interval, 21-28) per 100,000 population per year died after intensive care unit admissions with severe sepsis in the first 24 hrs. For intensive care unit admissions who met severe sepsis criteria in the first 24 hrs, median intensive care unit length of stay was 3.56 days (interquartile range, 1.50-9.32) and median hospital length of stay was 18 days (interquartile range, 8-36 days). These admissions used 45% of the intensive care unit and 33% of the hospital bed days used by all intensive care unit admissions. CONCLUSIONS: Severe sepsis is common and presents a major challenge for clinicians, managers, and healthcare policymakers. Intensive care unit admissions meeting severe sepsis criteria have a high mortality rate and high resource use.

Molecular characterization of clinical and environmental isolates of vancomycin-resistant Enterococcus faecium and Enterococcus faecalis from a teaching hospital in Wales.

The present study describes the first molecular characterization of environmental and clinical isolates of vancomycin-resistant enterococci (VRE) in Wales. Over a 3-month period (May-July 2000), 134 isolates of VRE (89 Enterococcus faecium and 45 Enterococcus faecalis) were isolated from the patient environment of the University Hospital of Wales (UHW) in Cardiff, Wales, UK. In addition, over the same time-period, 24 clinical isolates of VRE (20 isolates of E. faecium and four isolates of E. faecalis) were obtained from 14 patients. All study isolates were subjected to PFGE typing and their van genotypes were determined by using multiplex PCR. The vanA PCR product (231 bp) was evident in 146 (92 %) of 158 VRE isolates; the remaining 12 isolates (8 %) were positive for the vanB gene. All isolates of E. faecalis were found to be vanA-positive. In total, 16 PFGE banding profiles (pulsotypes) were observed for environmental isolates of E. faecium, whilst eight pulsotypes were found for isolates of E. faecalis. Some of these pulsotypes were isolated from multiple sites, whereas others were more restricted in their distribution. Eleven pulsotypes were evident for clinical isolates and eight of these (representing 11 isolates) were also encountered in environmental isolates. Eleven clinical isolates of E. faecium (55 %) shared an identical pulsotype that was not detected in environmental isolates. These results demonstrate a heterogeneous environmental population of VRE and an association of certain strains with clinical isolates. Predominance of a single pulsotype (not detected in the environment) amongst clinical isolates suggests non-environmental transmission between patients.

Identification and characterization of transmissible Pseudomonas aeruginosa strains in cystic fibrosis patients in England and Wales.

Most past studies of cross-infection with Pseudomonas aeruginosa among cystic fibrosis (CF) patients in the UK suggest that it is a rare occurrence. However, two recent reports of highly transmissible strains in patients in regional centres in England (Liverpool and Manchester) have raised questions as to the extent of the problem and prompted a nationwide survey to establish the distribution of P. aeruginosa strain genotypes among these patients. Isolates of P. aeruginosa were requested from over 120 hospitals in England and Wales and a sample size of approximately 20% of the CF patient population in each centre was recommended. In total, 1225 isolates were received from 31 centres (range 1 to 330). Single patient isolates were typed by SpeI macrorestriction and PFGE. A panel of strains of the common genotypes including representatives of reported transmissible strains was assembled and further characterized by fluorescent amplified fragment length polymorphism (FAFLP) genotyping. At least 72% of all patients harboured strains with unique genotypes. Small clusters of related strains were evident in some centres, presumably indicating limited transmission of local strains. The most prevalent strain was indistinguishable from that previously described as the 'Liverpool' genotype, and accounted for approximately 11% of patient isolates from 15 centres in England and Wales. The second most common genotype (termed Midlands 1) was recovered from 86 patients in nine centres and the third genotype, which matched closely the PFGE profile of Clone C, a genotype originally described in Germany, was found in eight centres and was isolated from 15 patients. A fourth genotype, identical to the published Manchester strain, was found in three centres. FAFLP analysis revealed some microheterogeneity among strains of the Liverpool genotype but all isolates of this genotype were positive by PCR for a strain-specific marker. These data suggest that cross-infection with P. aeruginosa has occurred both within and widely between CF centres in England and Wales. The two most common genotypes accounted for more than one-fifth of patients' isolates examined and transmissible genotypes were found in all but three centres studied. These results emphasize the need for continued surveillance of P. aeruginosa genotypes in CF patients to provide informed infection control policy in treatment centres.

Involving doctors in management. A survey of the management development career needs of selected doctors in NHS Wales.

Reports the results of a survey of 209 senior registrars and 269 consultants throughout Wales to identify the management development needs of doctors and ascertain their views of the value and utility of current management development course offerings in Wales. Finds that, currently, management development for doctors in Wales is unstructured and uncoordinated but, despite this, many doctors, especially senior registrars, appeared keen to increase their future involvement in management and held positive views regarding management and management development. The questionnaire also required doctors to rank order six managerial topics and their elements: financial, human resource, strategic, operational, service quality and self-management. Of these, self-management issues were rated highest and there was some congruity in the rankings of the six topics by senior registrars and the other three consultant categories. Overall, managing a budget, medical and clinical audit, negotiating skills and leadership skills were ranked highest for inclusion in management development while project management, quality circles and equal opportunities received the lowest ratings.

The role of alcohol and drugs in homicides in England and Wales.

BACKGROUND: The annual number of homicide convictions in England and Wales is increasing. Previous studies have highlighted the aetiological role of alcohol and drugs in homicide. AIMS: To examine rates of alcohol and drug misuse and dependence in people convicted of homicide; the role of alcohol and drugs in the offence; the social and clinical characteristics of alcohol- and drug-related homicides; and the social and clinical characteristics of patients with dual diagnosis who commit homicide. METHODS: A national clinical survey based on a 3-year (1996-9) consecutive sample of people convicted of homicide in England and Wales. Information on rates of alcohol and drug misuse/dependence, the role of alcohol and drugs in the offence and social and clinical characteristics of perpetrators were collected from psychiatric reports prepared for the court in homicide convictions. Detailed clinical information was gathered from questionnaires completed by mental health teams for those in contact with mental health services. RESULTS: Of the 1594 homicide perpetrators, more than one-third (42%) occurred in people with a history of alcohol misuse or dependence and 40% in people with a history of drug misuse or dependence. Alcohol or drug misuse played a contributory role in two-fifths of homicides. Alcohol played a major role in 52 (6%) and a minor role in 364 (39%) homicides. Drugs played a major role in six (1%) and a minor role in 138 (14%) homicides. Forty-two homicides (17%) were committed by patients with severe mental illness and substance misuse. Alcohol- and drug-related homicides were generally associated with male perpetrators who had a history of violence, personality disorders, mental health service contact and with stranger victims. CONCLUSIONS: Substance misuse contributes to the majority of homicides in England and Wales. A public health approach to homicide would highlight alcohol and drugs before severe mental illness.

Management of pregnancy and childbirth in England and Wales and in France.

This paper reviews national data on obstetric and neonatal practices in England and Wales, and in France between 1970 and 1980. The data have been derived from national statistics and surveys on national samples of births in 1970, 1975 and 1980 in England and Wales, and 1972, 1976 and 1981 in France. The analysis shows that there was no major difference in pregnancy outcome, but wide variations in medical practices, and their trend over time. The main differences were: in England and Wales a higher number of antenatal visits, a higher percentage of inpatient admissions during pregnancy, a higher rate of induction, more episiotomies, a higher rate of resuscitation at birth, and admission to neonatal special care units; in France, a higher rate of caesarean sections before and during labour, some evidence of a more active management of labour, and a longer hospital post-natal stay. These differences in practice reflect differences in objectives and assessment of the effectiveness of care between the two countries: they point out the need for better monitoring and evaluation of obstetric and neonatal practices.

The specialist learning disability nurse in Wales.

This paper reflects on the development of services for people with learning disabilities within the United Kingdom and focuses on the role of the specialist nurse. The nurse's contribution to the care of this client group has been the subject of debate and controversy for a number of years. Developments within the learning disability filed in Wales in particular are explored, with the All Wales Strategy for People with Learning Disabilities providing the background and context for these developments. An example of how specialist nurses from around Wales came together in order to share good and best practice is discussed. The conclusion is that the specialist learning disability nurse has a great deal to offer, but must be prepared to work together with other professionals as well as service users and their families.

Childhood injury mortality in New South Wales: geographical and socio-economic variations.

This paper reports a retrospective study of deaths due to unintentional injury in children aged between 0 and 14 years of age in New South Wales between 1985 and 1987. The aims were to determine whether the pattern of child injury mortality differed between rural and metropolitan New South Wales and to establish the relationship between socio-economic status, based on a geographical indicator of socio-economic status and child injury mortality. The child injury mortality rate for New South Wales in 1985-87 was 12.3 deaths per 100,000 population per year. The rate in the country area of 15.3 deaths per 100,000 was significantly higher than that for the metropolitan area of 11.3 per 100,000 (P < 0.05). Deaths of passengers in motor vehicle traffic accidents (P < 0.01) and deaths due to fires (P < 0.01) were greater in the country area. A negative linear association between socio-economic status and child injury mortality was found in the Sydney metropolitan area (P < 0.01). This trend was most apparent for deaths of child pedestrians (P < 0.01).

Information sources used by New South Wales cancer clinicians: a qualitative study.

BACKGROUND: This study identified (i) information sources used by cancer clinicians to guide pharmacological treatments, (ii) utilization of, and opinions about, online information sources and (iii) clinicians' ability to access a specific cancer treatment protocol (escalated bleomycin, etiposide, doxorubicin, cyclophosphamide, vincristine, procarbazine, prednisone (BEACOPP) for Hodgkin's Lymphoma). The work was carried out before activation of the Cancer Institute New South Wales Standard Cancer Treatment (CI-SCaT) programme. METHODS: We conducted semistructured interviews with a purposeful sample of senior and junior doctors, nurses and pharmacists treating adult cancer patients (n = 32) in eight New South Wales public hospitals. RESULTS: Information seeking processes are context specific and vary from clinician to clinician and ward to ward. Clinicians use human, electronic and printed information sources at, or close to, the point of patient care; however, experienced colleagues are preferred where information is needed quickly or in unfamiliar clinical situations. Barriers to using online cancer information are environmental (hardware, connection speeds, time), personal (poor computer literacy and lack of awareness of appropriate sites) and economic (costs of journal subscriptions). Just over half of participants were able to locate a specific cancer protocol and none of these protocols was fully consistent with CI-SCaT recommendations. CONCLUSION: There is no standardized approach to the pharmacological treatment of cancer patients in this sample of New South Wales clinicians. CI-SCaT will fill a gap with respect to standardizing oncology treatment. However, to ensure maximal CI-SCaT uptake, implementation plans should harness positive behavioural influences and attempt to modify the negative forces that act on hospital clinicians in their day-to-day work.

Benign ovarian cysts in England and Wales and in the United States.

OBJECTIVE: To compare the rates of hospital admission for management of ovarian cysts in England and Wales and the United States between 1972 and 1974 and 1984 and 1986; and to determine whether these rates are related to rates of early diagnosis of ovarian cancer. DESIGN: Analysis of published and unpublished hospital discharge data based on national samples, the Hospital In-patient Enquiry (HIPE), a 10% hospital discharge sample for England and Wales, and the National Hospital Discharge Survey (NHDs), a 5% sample for the United States. MAIN OUTCOME MEASURES: Age-specific discharge rates for primary and secondary diagnoses of ovarian cyst or benign ovarian tumour. RESULTS: There was an age-adjusted increase in discharge rates of about 8% in both countries; discharge rates in the United States were approximately double those in England and Wales in both time periods. There was no difference in the rates of early diagnosis of ovarian cancer. CONCLUSIONS: Ovarian cysts are a common cause of hospital admission in both countries. The higher rates in the United States are not associated with earlier diagnosis of ovarian cancer.

Management of genital chlamydial infections at termination of pregnancy services in England and Wales: where are we now?

OBJECTIVE: To determine the range of policies and practices related to the management of genital chlamydial infection employed at termination of pregnancy services in England and Wales. DESIGN: Cross-sectional descriptive study. SETTING: England and Wales. POPULATION: Termination of pregnancy providers. METHODS: Survey questionnaire administered to termination of pregnancy providers. MAIN OUTCOME MEASURES: Policies and practices for the management of genital chlamydial infection in women seeking termination of pregnancy with comparison to the national guidelines of the chief medical officer (CMO) and the Royal College of Obstetricians and Gynaecologists (RCOG). RESULTS: One hundred and thirty-eight (48%) practices responded to the survey, with representation across England and Wales. Policies for screening and/or treatment of chlamydial infection existed for 70% of providers. We found three practice patterns for the management of genital chlamydial infection among termination of pregnancy attenders: 70% of providers tested their own attenders prior to termination and treated if necessary; about 25% of providers administered prophylaxis without testing; and a small number of providers (< 5%) neither tested nor treated attenders. CONCLUSION: These patterns may be the result of differences in the CMO and RCOG guidelines. Given the impact of untreated genital chlamydial infection in women attending for termination, consistent recommendations from the CMO and RCOG may encourage uniform practice for the management of chlamydial infection in this vulnerable population.

Creation and development of an All-Wales Health Library Catalogue.

This article focuses on the collaboration between the University of Wales College of Medicine (UWCM) libraries and the Welsh National Health Service (NHS) libraries to create a joint library catalogue. The goal was to create an all-Wales resource that gave users one access point to search for the location and availability of health-related material in any Welsh medical library. This venture grew out of the existing collaborative scheme, the All-Wales Health Information and Library Extension Services (AWHILES). Currently, all seven UWCM libraries and 17 NHS libraries contribute to the catalogue. Four more libraries are due to join in late 2003 or early 2004. All UWCM and AWHILES libraries would then be contributing members of the joint catalogue. The article discusses the background and motivation to the creation of the database. It explores the positives and negatives of the project plus what was learnt as the venture progressed. It reviews the establishment and operations of the Welsh Health Voyager User Group (WHVUG) created to involve all contributing members in the running and future development of the library catalogue.

Snake envenomation in dogs in New South Wales.

OBJECTIVE: To obtain baseline data on the prevalence of elapid snake envenomation in dogs presented to veterinary practices in New South Wales and to assess attitudes of veterinarians to this clinical entity. PROCEDURE: A mailed questionnaire, sent to all veterinary clinics within New South Wales, was utilised to collect epidemiological information regarding elapid snake envenomation in dogs. RESULTS: A response rate of 68% was obtained and a yearly prevalence of snake envenomation in dogs across New South Wales veterinary clinics was estimated as 0.31%. The most common species reported to be responsible for envenomation within NSW was the Red Bellied Black snake (Pseudechis porphyriacus) followed by the Brown snake (Pseudonaja textilis) and then Tiger snake (Notechis scutatus). The reported envenomation syndromes caused by these common snake species were perceived to be similar for Brown and Tiger snakes but differed for Red Bellied Black snakes. Diagnosis of snake envenomation was based predominantly on the recognition of clinical signs. Specific diagnostic tests, such as venom detection kits, were used infrequently. The most common treatment was reported to be a combination of intravenous fluid therapy and antivenom, and monitoring of response to this treatment was usually through assessment of clinical signs. Survival after antivenom administration was reported to be highest for Red Bellied Black snake species. Survival was perceived to be associated with time between envenomation and presentation to the veterinary clinic and with antivenom administration. CONCLUSIONS: Current attitudes and perceptions of veterinarians have been defined. Diagnosis of species-specific snake envenomation is shown to be made on the basis of clinical signs which are, however, reported as similar for each species. Clearer definition of these envenomation syndromes and identification of accessible diagnostic testing procedures are needed.

Establishing a people-centered health service in Gwent, Wales.

The Welsh Health Planning Forum has developed a "Strategic Intent and Direction for the NHS in Wales." The aim is "to take the people of Wales into the 21st Century with a level of health on course to compare with the best in Europe" (Welsh Office NHS Directorate, The Welsh Health Planning Forum, 1989). Gwent Health, one of the nine health authorities in Wales, provides a comprehensive health service to its population of 445,000 and was chosen to develop a prototype for the provision of cancer services. Gwent residents were invited to seminars to express their opinions of the health service that was provided and describe the type of service they would like to have in the future. The response was encouraging enough to engender the planning of future seminars.

The epidemiology of subacute sclerosing panencephalitis in England and Wales 1990-2002.

AIM: To assess the impact of measles/mumps/rubella (MMR) vaccine on the epidemiology of subacute sclerosing panencephalitis (SSPE) in England and Wales. METHODS: Cases of SSPE resident in England and Wales with onset between 1990 and 2002 were reviewed. RESULTS: A total of 47 cases were identified, 31 male and 16 female. There was an average annual decline of 14% in SSPE onset over the period, consistent with the decline in notified measles over the last 20 years. A history of measles was present in 35 (median age 1.3 years), the most recent recorded date being 1994; the interval from measles to onset of SSPE ranged from 2.7 to 23.4 years. Four children with a history of receipt of a measles containing vaccine were reported not to have had measles; two of these cases had a brain biopsy, and nucleotide sequence data confirmed wild measles infection. Brain biopsy specimens from a further three cases with a history of measles, of whom two had also had a history of vaccination, showed wild-type strain. CONCLUSION: The prevention of endemic circulation of measles virus in England and Wales through the high coverage achieved with MMR vaccine, together with the measles/rubella vaccination campaign of 1994, has resulted in the near elimination of SSPE. However, the recent decline in MMR vaccine coverage, with the associated increase in localised measles outbreaks and cases in young infants, is of concern. It underlines the importance of maintaining high vaccine coverage in order to protect indirectly those most vulnerable to SSPE, namely infants too young to be vaccinated.
