Displacement of Canada's largest public illicit drug market in response to a police crackdown.
(49/334)
BACKGROUND: Law enforcement is often used in an effort to reduce the social, community and health-related harms of illicit drug use by injection drug users (IDUs). There are, however, few data on the benefits of such enforcement or on the potential harms. A large-scale police "crackdown" to control illicit drug use in Vancouver's Downtown Eastside provided us with an opportunity to evaluate the effect. METHODS: As part of our ongoing prospective cohort study of IDUs in Vancouver, we examined data collected from 244 IDUs in the 3 months before the police crackdown and from 142 IDUs in the 3 months after the start of the crackdown, on Apr. 7, 2003. All study subjects were active drug users. We also examined external data on needle exchanges and syringe disposal. RESULTS: The 2 groups of IDUs were statistically similar: they were mainly young (mean age 39 years) and male (63%), and they had injected illicit drugs for 13 years on average. Ethnic background and the proportion homeless were also similar. There were no statistically significant reported differences (all p > 0.1) in the street price of heroin, cocaine or "crack" in the 2 periods. In the 3-month periods before and after the crackdown, respectively, the rates of daily heroin injection were 27.9% and 26.8%, daily cocaine injection 28.7% and 27.5%, and daily crack use 59.4% and 60.6% (all p > 0.1). The proportions of study subjects receiving methadone treatment, 41.0% and 44.4% (p = 0.516), did not differ. However, the proportions reporting a change in where drugs were used, 22.5% and 33.8% (p < 0.05), and the proportions reporting a change in the neighbourhood of use because of police presence, 18.1% and 26.8% (p < 0.05), increased significantly. Needle-exchange data confirmed that the community levels of drug use were unchanged. Disposal statistics demonstrated that the monthly average number of used syringes found on the streets outside the traditional area of drug use increased from 784 in the 3 months before Apr. 1 to 1253 in the subsequent 3 months (p = 0.002) and the monthly average number of used syringes found in public boxes for the safe disposal of syringes decreased from 865 to 502 (p = 0.018). INTERPRETATION: The effort to control illicit drug use did not alter the price of drugs or the frequency of use, nor did it encourage enrollment in methadone treatment programs. Several measures indicated displacement of injection drug use from the area of the crackdown into adjacent areas of the city, which has implications for both recruitment of new initiates into injection drug use and HIV prevention efforts.

Harlem service providers' perceptions of the impact of municipal policies on their clients with substance use problems.
(50/334)
Substance abuse is a significant health and social problem in many low-income urban communities. Finding appropriate help for drug users has been identified as a significant barrier to reducing the harm from drug abuse. This report presents findings from a survey of service providers in the Central and East Harlem communities, New York City, conducted in 2000 to identify policy obstacles that impeded clients' attempts to overcome substance use and related problems. Policies can affect substance users by making access to drug treatment more difficult or by imposing unrealistic expectations on substance users for eligibility for benefit programs. Respondents to the survey were asked to rate 30 specific policies as harmful or helpful to their clients and to assess how the policies acted as barriers or facilitators to getting services and reducing drug use. Eleven policies in the areas of drug treatment, corrections, and Medicaid were rated as harmful to their clients by more than 50% of the respondents. We discuss the implications of these and other findings for drug users' ability to seek and receive help for their problems. (+info)
Development, utilisation, and importance of accident and emergency department derived assault data in violence management.
(51/334)
OBJECTIVES: To develop formal processes for the collection, disclosure, and effective use of accident and emergency (A&E) department derived assault injury data for city violence reduction. METHODS: Over a four year period, managed by a multi-agency steering group, A&E data collection, collation, and disclosure processes were developed, instituted, and refined. Consultations and negotiations between agencies identified the most effective and ethical methods, appropriate recipients, and the nature of the information of most use. RESULTS: Disclosure of A&E data to city authorities, the police, and local media drew substantial attention and crime prevention resources to the locations of violence. As a result, a police task force responsible for targeting city street crime was funded, which analysed both A&E and police information. Monthly, electronic transfer of raw, anonymous data to the task force crime analyst informed and prompted violence prevention initiatives by several agencies. Police mounted overt and covert interventions targeted at violence hotspot licensed premises and used the data to oppose, on injury grounds, drinks/entertainment licence applications. Transport authorities established new half hourly night time city centre bus services. The local authority mounted an assault awareness campaign in schools and public libraries, and licensing magistrates used the data to measure, for example, the impact of continuous 36 hour drinks licensing on public safety. CONCLUSIONS: The principal finding of this evaluation was that judicious sharing of unique information about locations and times of violence derived from A&E patients was a powerful and effective means of targeting police and other local resource to bring about violence reduction.

Biomonitoring of traffic police officers exposed to airborne platinum.
(52/334)
BACKGROUND: Over the past two decades there has been a substantial increase in environmental levels of palladium, platinum, and rhodium, the platinum group elements (PGEs), due to the widespread use of catalytic converters for automotive traction. AIM: To evaluate urinary platinum levels in occupationally exposed subjects. METHODS: A total of 161 employees from the Rome City Police Force were studied; 103 were traffic police involved in controlling streets with an average flow of vehicles, while the remaining 58 were control subjects engaged only in office work. Platinum quantification in the urine samples of these subjects was carried out by sector field inductively coupled plasma mass spectrometry. RESULTS: There were no statistically significant differences between platinum levels in the group of subjects engaged in traffic control and the control group (4.45 (2.42) ng/l v 4.56 (2.84) ng/l, respectively). CONCLUSIONS: Urinary levels were found to be higher than those reported for other urban populations, thus showing a progressive increase in human exposure to Pt. (+info)
Ambulatory (24 hour) blood pressure monitoring in police officers.
(53/334)
The aim of the study is to evaluate, by ambulatory (24 h) blood pressure monitoring (ABPM), whether police officers exposed to urban pollutants and possible psycho-social stressors could be at risk of changes in ambulatory systolic blood pressure (SBP), and ambulatory diastolic blood pressure (DBP) compared to controls. After excluding the principal confounding factors, police officers and controls have been subdivided into non-smoker and smoker subjects. Police officers were compared by sex, age, length of service, family history of cardiovascular disease, serum total cholesterol, serum HDL cholesterol, serum LDL cholesterol, plasma triglyceride, body mass index (BMI kg/m (2)) and drinking habits with controls. Smoker police officers were compared with controls also by the smoking habit. In the non smoker group 77 police officers with outdoor activity (38 men and 39 women) and 87 controls with indoor activity (43 men and 44 women) were studied. In the smoker group 43 police officers (21 men and 22 women) and 29 controls (15 men and 14 women) were studied. In non smoker male police officers ambulatory SBP mean values during 24 h, during day-time and during night-time were significantly higher than controls. In the same group ambulatory DBP values during 24 h and between 6 AM and 11 AM and between 10 PM and 6 AM were significantly higher in police officers than controls. The results suggest that occupational exposure to urban pollutants and possible psycho-social stressors could cause changes in ABPM values in male police officers compared to controls. (+info)
Characterizing perceived police violence: implications for public health.
(54/334)
Despite growing recognition of violence's health consequences and the World Health Organization's recent classification of police officers' excessive use of force as a form of violence, public health investigators have produced scant research characterizing police-perpetrated abuse. Using qualitative data from a study of a police drug crackdown in 2000 in 1 New York City police precinct, we explored 40 injection drug using and 25 non-drug using precinct residents' perceptions of and experiences with police-perpetrated abuse. Participants, particularly injection drug users and non-drug using men, reported police physical, psychological, and sexual violence and neglect; they often associated this abuse with crackdown-related tactics and perceived officer prejudice. We recommend that public health research address the prevalence, nature, and public health implications of police violence. (+info)
Self-reported experiences of health services among female street-based prostitutes: a cross-sectional survey.
(55/334)
BACKGROUND: Previous studies show that women working in prostitution do not use routine health services appropriately. Little is known about the nature and frequency of service contacts or barriers to access. This information is needed if use of current services by this group is to improve. AIM: To identify barriers reducing access to health services by street prostitutes, and to identify current patterns of use. DESIGN OF STUDY: Cross-sectional survey. SETTING: Inner-city Bristol. METHOD: Seventy-one female street-based prostitutes were interviewed about their experiences of health services. RESULTS: The women had frequent contacts with healthcare providers. The general practitioner (GP) was the main source of all types of care. Although 83% (59/71) were registered with a GP, 62% (36/59) had not disclosed their work. Only 46% (33/71) had been screened for sexually transmitted infection in the previous year and 24% (17/71) were vaccinated against hepatitis B, a national recommendation for sex workers. Only 38% (25/65) had had cervical smears according to screening guidelines. Opportunistic screening and care was important. While pregnant with their last child, only 30% (14/47) booked in the first trimester and attended all antenatal appointments, with 13% (6/47) receiving no antenatal care until admitted in labour. Appointments, waiting times, and fear of judgement and other patients staring, were considered significant barriers to service use. The model suggested by the women was an integrated service providing basic living needs alongside health care. CONCLUSION: Non-disclosure and poor attendance for follow-up make appropriate care difficult, and may contribute to poor health. Despite frequent service contacts, opportunities for care are being missed. (+info)
Comprehensive and human capital crash costs by maximum police-reported injury severity within selected crash types.
(56/334)
This paper presents estimates for both the economic and comprehensive costs per crash for three police-coded severity groupings within 16 selected crash types and within two speed limit categories (or=50 mph). The economic costs are hard dollar costs. The comprehensive costs include economic costs and quality of life losses. We merged previously developed costs per victim keyed on the Abbreviated Injury Scale (AIS) into US crash data files that scored injuries in both the AIS and police-coded severity scales to produce per crash estimates. The most costly crashes were non-intersection fatal/disabling injury crashes on a road with a speed limit of 50 miles per hour or higher where multiple vehicles crashed head-on or a single vehicle struck a human (over 1.69 and $1.16 million per crash, respectively). The annual cost of police-reported run-off-road collisions, which include both rollovers and object impacts, represented 34% of total costs. (+info)
