Real-world hepatitis C treatment outcomes and reinfections among people who inject drugs at a needle and syringe program in Stockholm, Sweden. Harm Reduct J 2023; 20:72. [PMID: 37308951 DOI: 10.1186/s12954-023-00801-1] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/21/2022] [Accepted: 06/03/2023] [Indexed: 06/14/2023] Open
Abstract
BACKGROUND People who inject drugs (PWID) represent a population with an increased prevalence of hepatitis C (HCV) infections. HCV treatment among PWID is essential to reach the WHO goal of eliminating HCV as a major public health threat by 2030. Despite better understanding of PWID subgroups and changes in risk behaviors over time, more knowledge about HCV treatment outcomes in different HCV prevalence populations and settings is warranted to enhance the continuum of care. METHODS All Stockholm Needle and Syringe Program (NSP) participants who initiated HCV treatment between October 2017 and June 2020 were HCV RNA tested at end of treatment and twelve weeks thereafter to confirm cure with a sustained virological response (SVR). All cured participants were prospectively followed from SVR to the last negative HCV RNA test or a subsequent reinfection, until October 31, 2021. RESULTS Overall, 409 NSP participants initiated HCV treatment, 162 at the NSP and 247 in another treatment setting. There were a total of 6.4% treatment dropouts (n = 26), 11.7% among participants treated at the NSP and 2.8% among those treated elsewhere (p < 0.001). Stimulant use (p < 0.05) and not being in an opioid agonist treatment program (p < 0.05) was associated with dropout. More participants treated outside the NSP were lost to follow-up between end of treatment and SVR (p < 0.05). During follow-up post-SVR, 43 reinfections occurred, corresponding to a reinfection rate of 9.3/100 PY (95% CI 7.0, 12.3). Factors associated with reinfection were younger age (p < 0.001), treatment while in prison (p < 0.01) and homelessness (p < 0.05). DISCUSSION In this high HCV prevalence NSP setting, with a majority of stimulant users, treatment success was high and the level of reinfections manageable. To reach HCV elimination, there is a need to target specific PWID subgroups for HCV treatment, in both harm reduction and adjacent healthcare settings frequented by PWID.

Factors associated with non-walking 4 months after hip fracture. A prospective study of 23,759 fractures. Injury 2022; 53:2180-2183. [PMID: 35307165 DOI: 10.1016/j.injury.2021.10.031] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/10/2021] [Revised: 10/07/2021] [Accepted: 10/27/2021] [Indexed: 02/02/2023]
Abstract
INTRODUCTION Despite advances in new surgical techniques and improvements in medical care of the last decades a considerable number of patients will not regain their ability to walk after a hip fracture. AIMS To further identify risk factors associated with non-walking 4-months after a hip fracture. MATERIAL AND METHODS Register-based, longitudinal study with a 4-month follow-up. The collected data from the Swedish hip fracture registry, RIKSHÖFT, contained all hip fracture between 201301-01-2015-12-31 in Sweden. All patients older than 50 years with a non-pathological fracture and who were able to walk before the fracture were included. The association of sex, age, general health, dementia and type of discharge with complete loss of walking after a hip fracture were investigated using a multivariate analysis. RESULTS Included were 23,759 patients. At the 4-month follow-up, 10% were unable to walk. Twenty-five per cent of patients with dementia lost their ability to walk compared to 7% of those with no cognitive dysfunction. Adjusted odds ratio (OR) for factors associated with loss of walking ability were; discharge to institutionalized care rather than their own home or a rehabilitation unit (OR=1.91; 95% CI=1.67-2.18), dementia (OR=1.80; 95% CI=1.57-2.06), male gender (OR=1.59; 95% CI=1.40-1.81) and ASA score grade III-V (OR=1.37; 95% CI=1.20-1.55) but not age (OR=1.01; 95% CI=1.00-1.02). CONCLUSIONS An important factor associated with a complete loss of walking ability after a hip fracture is the discharge to institutionalized care. This factor might be influenced either by favouring rehabilitation units or by improving the rehabilitation protocols.

Health literacy and changes in pattern of drug use among participants at the Stockholm Needle Exchange Program during the COVID-19 pandemic. Harm Reduct J 2021; 18:52. [PMID: 33971892 PMCID: PMC8107802 DOI: 10.1186/s12954-021-00499-z] [Citation(s) in RCA: 11] [Impact Index Per Article: 3.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/06/2021] [Accepted: 04/29/2021] [Indexed: 02/06/2023] Open
Abstract
Background and aims People who inject drugs may be particularly vulnerable to the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) due to underlying health problems, stigma and social vulnerabilities. Harm reduction services, including needle exchange programs (NEP), have been subjected to varying degrees of disruption in the world, especially in the beginning of the coronavirus disease 2019 (COVID-19) pandemic. Compared to responses in other countries, Sweden’s initial strategy toward limiting the spread and impact of COVID-19 was less restrictive to its citizens with no imposed general societal lockdown. In this study, we investigate changes in drug use patterns, utilization of NEP associated health services, COVID-19 health literacy and the prevalence of SARS-CoV-2 antibodies among NEP clients in Stockholm during the COVID-19 pandemic.
Methods NEP visits and services provided (needles/syringes, HIV and hepatitis C tests and treatment, naloxone distributed) and overall mortality among NEP clients between January 1 and October 31, 2020, were used for trend analyses in comparison with corresponding 2019 data. Between July 27 and October 2, 2020, NEP clients (n = 232) responded to a 27 item COVID-19 Health Literacy Questionnaire. SARS CoV-2 IgG antibody tests (n = 779) were performed between June 15 and October 31, 2020. Results During the COVID-19 pandemic number of clients, client visits, naloxone distribution and HCV tests remained stable compared to 2019, while distribution of needles/syringes increased (p < 0.0001); number of HIV tests and HCV treatments decreased (p < 0.05); and mortality decreased (< 0.01). Overall, the level of health literacy concerning transmission routes and protective measures was high. SARS-CoV-2 antibody prevalence was 5.4% (95% CI 4.0–7.2). Conclusions The Stockholm NEP managed to maintain a high level of clients and services during the pandemic. In general, COVID-19 health literacy was adequate and the overall SARS-CoV-2 antibody prevalence was low compared to the general population, which highlights a need for prioritized and targeted COVID-19 vaccination among PWID.

Abstract
Summary
Objectives: To evaluate Use Case Maps (UCMs) as a technique for Requirements Engineering (RE) in the development of information systems with functions for spatial analyses in inter-organizational public health settings.
Methods: In this study, Participatory Action Research (PAR) is used to explore the UCM notation for requirements elicitation and to gather the opinions of the users. The Delphi technique is used to reach consensus in the construction of UCMs.
Results: The results show that UCMs can provide a visualization of the system‘s functionality and in combination with PAR provide a sound basis for gathering requirements in inter-organizational settings. UCMs were found to represent a suitable level for describing the organization and the dynamic flux of information including spatial resolution to all stakeholders. Moreover, by using PAR, the voices of the users and their tacit knowledge is intercepted. Further, UCMs are found useful in generating intuitive requirements by the creation of use cases.
Conclusions: With UCMs and PAR it is possible to study the effects of design changes in the general information display and the spatial resolution in the same context. Both requirements on the information system in general and the functions for spatial analyses are possible to elicit when identifying the different responsibilities and the demands on spatial resolution associated to the actions of each administrative unit. However, the development process of UCM is not well documented and needs further investigation and formulation of guidelines.

Usual drinking patterns and non-fatal injury among patients seeking emergency care. Public Health 2006; 120:1064-73. [PMID: 17007896 DOI: 10.1016/j.puhe.2006.06.007] [Citation(s) in RCA: 11] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/14/2005] [Revised: 04/21/2006] [Accepted: 06/16/2006] [Indexed: 10/24/2022]
Abstract
OBJECTIVES To explore the association between drinking patterns, irrespective of whether alcohol was consumed in the event of the injury or not, and different injury variables; and to identify settings and situations in which risky drinkers have an increased likelihood of injury. STUDY DESIGN The study population consisted of all patients aged 18-70 years registered for an injury according to ICD-10 at a Swedish emergency department during an 18-month period. After informed consent, the injury patients were screened for drinking habits by the AUDIT-C questionnaire. The gender, age and drinking pattern of injury patients were compared with the general population. METHODS A total of 2782 patients aged 18-70 years were registered for an injury during the study period. The number of drop-outs was 631. Drop-outs include those who did not consent to participate, were severely injured, too intoxicated or did not fill out the questionnaire satisfactory. Thus, 77.3% of the target group were included for further analysis (1944 drinkers and 207 abstainers). The patients were categorized into three drinking categories: abstainers, non-risky and risky drinkers. Risky drinkers were defined according to usual weekly consumption of 80g or more of alcohol for women and 110g or more for men and/or heavy episodic drinking (i.e. having six glasses or more one glass=12g alcohol), or both, on one occasion at least once a month, valid for both women and men. To estimate the relationship between drinking patterns and the injury variables (environment, cause of injury, activity and diagnosis), odds ratios (OR) were calculated by logistic regression. Multiple logistic regression was used in order to control for age and sex differences between the various drinking and injury categories. RESULTS The proportion of risky drinkers was higher in the study population compared with the general population in the same area. When controlling for age and sex, risky drinkers (OR 6.4(adj) Confidence interval CI 1.9-21.2) and non-risky drinkers (OR .4.5(adj) CI 1.4-14.5) displayed an increased risk for injury compared with abstainers, in amusement locations, parks, by or on lakes or seas, especially while engaged in play, hobby or other leisure activities (risky drinkers: OR 2.8(adj) CI 1.3-5.6; non-risky drinkers: OR 2.4(adj) CI 1.2-4.6). All differences between drinking patterns in external cause of injury disappeared when age and sex were considered. During rest, meals and attending to personal hygiene, the non-risky drinkers had a lower probability of injury compared with abstainers (OR 0.3(adj) CI 0.1-0.8). Non-risky drinkers had a higher probability than abstainers of suffering luxation (dislocation) or distortion (OR 1.6(adj) CI 1.1-2.5). Nine per cent of the study population reported that they believed that their injury was related to intake of alcohol. Half of this group were non-risky drinkers (CI for the 13.7% difference was 9.7-17.6). CONCLUSIONS Few significant associations between drinking pattern and injury remained when age and sex were controlled for.

The impact of home safety promotion on different social strata in a WHO safe community. Public Health 2006; 120:427-33. [PMID: 16566951 DOI: 10.1016/j.puhe.2005.12.002] [Citation(s) in RCA: 6] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/14/2005] [Revised: 11/21/2005] [Accepted: 12/07/2005] [Indexed: 11/21/2022]
Abstract
OBJECTIVES Few studies have investigated the impact of home safety promotion programmes on different social strata. The aim of this study was to investigate the distribution of effects of a community-based home safety programme on home injury rates among families with different connections to the labour market. METHODS A quasi-experimental design was used, with pre- and post-implementation registrations covering the total populations below 65 years of age in the programme implementation area (population 41,000) and in a neighbouring comparison municipality (population 26,000) in Ostergötland County, Sweden. RESULTS In the intervention and comparison areas, households in which the adults were not vocationally active displayed the highest rates of home injury. After 6 years of programme activity, the home injury rates for males and females in all social status categories displayed a decreasing trend in the intervention area. The opposite was true for the comparison area, i.e. the incidence of injury increased, with the exception of females in non-vocationally active households. The decline in injury rates in the intervention area was statistically significant for males and females in the employed category and for males in the non-vocationally active category. Changes in injury rates in the comparison area were not statistically significant. CONCLUSION The programme was partially successful in that it reduced the injury rate in non-vocationally active households, but it did not influence the injury rate in the employed households. The study design did not allow for conclusions regarding why the post-intervention injury rates remained higher in non-vocationally active households. Further research on the association between the incidence of home injury and socio-economic factors is warranted.

Abstract
Excessive alcohol consumption is common among injury patients, but routine alcohol interventions seem to be difficult to implement in emergency departments. An obstacle seen in previous studies is the limited time available in a real-world setting for staff to participate in routine alcohol screening and interventions. In the present study, ordinary staff participated in a simple alcohol screening procedure. The aim of the study was to evaluate the feasibility of this procedure and if there was any change in attitudes and practices among triage staff after the implementation. We analyzed interviews with six staff members and questionnaires completed by 29 nurses and medical secretaries before and after a period of systematic routine screening. The staff reported that the routine worked well and that few patients reacted negatively. A positive change was seen in attitudes towards alcohol preventive measures in general. However, this seems not to be sufficient for the staff to spontaneously engage more actively. In fact, more of the staff were uncertain after the study period whether the emergency department is an appropriate place for alcohol screening and intervention despite an increased role legitimacy and perceived competence. There is a need for further development of alcohol prevention models that are acceptable for the staff to implement as part of the daily routine.

Abstract
OBJECTIVES As physical activity is promoted as part of a healthy lifestyle, sports injuries are becoming an important public health concern in many countries. The objective of this study is to investigate rates of sports injuries before and after implementation of a WHO Safe Community program. METHODS Sports injury data were collected pre- and post-implementation from all individuals below 65 years of age during 1 year in the targeted municipality (population 41,000) and in a control municipality (population 26,000). A quasi-experimental design was used and individuals were divided into three categories based on household relationship to the labour market. RESULTS There were no differences between socio-economic categories regarding pre-intervention injury rates. No statistically significant post-intervention changes in injury rate were observed in the control area or among any females in either area. In the intervention area, a statistically significant (p = 0.011) decrease in injury rate was observed among male members of households in which the vocationally important member was employed. A statistically significant decrease was observed in injuries sustained in team sports among male members of households in which the vocationally important member was employed (p = 0.001) and among members of households in which the vocationally important member was self employed (p<0.05). CONCLUSIONS The study indicates areas for improvement in the civic network based WHO Safe Community model. The results show that females, participants in individual sports, and members of non-vocationally active households were less affected by the interventions. These facts have to be addressed in planning future community based sports injury prevention programmes and their evaluations.

Abstract
BACKGROUND Although social inequality in health has been an argument for community-based injury prevention programmes, intervention outcomes with regard to differences in social standing have not been analysed. The objective of this study was to investigate rates of injuries treated in health-care among members of households at different levels of labour market integration before and after the implementation of a WHO Safe Community programme. METHODS A quasi-experimental design was used with pre- and post-implementation data collection covering the total populations <65 years of age during one year in the programme implementation municipality (population 41 000) and in a control municipality (population 26 000). Changes in injury rates were studied using prospective registration of all acute care episodes with regard to social standing in both areas during the study periods. RESULTS Male members of households categorized as not vocationally active displayed the highest pre-intervention injury rates. Also after the intervention, males in households classified as not vocationally active displayed notably elevated injury rates in both the control and study areas. Households in the study area in which the significant member was employed showed a post-intervention decrease in injury rate among both men (P < 0.001) and women (P < 0.01). No statistically significant change was observed in households in which the significant member was self-employed or not vocationally active. In the control area, only an aggregate-level decrease (P < 0.05) among members of households in which the significant member was employed was observed. CONCLUSIONS The study displayed areas for improvement in the civic network-based WHO Safe Community model. Even though members of non-vocationally active households, in particular men, were at higher pre-intervention injury risk, they were not affected by the interventions. This fact has to be addressed when planning future community-based injury prevention programmes.

Abstract
This paper deals with some important mechanical properties (hardness, dimensional stability, compressive and flexural strength) of an experimental version of a translucent calcium aluminate dental restorative material. All samples investigated have been made from pre-pressed tablets, with a compaction degree of approximately 60%, hydrated using a 0.15 wt % Li salt solution as an accelerator. The samples were stored in water at 37 degrees C between the measurements. As reference materials one composite, Tetric Ceram, and one glass ionomer, Fuji II, were used with specimens prepared according to the manufacturer's recommendations. For the reference materials some of the properties were published data. The results show that the calcium aluminate material has sufficient mechanical properties to be used as a permanent dental restorative taking as a reference the ISO 9917 and the ISO 4049 as well as the reference materials. In addition the results indicate that the mechanical properties are controlled by the microstructure, which is mainly determined by the grain size of the filler.

OBJECTIVES To evaluate the outcome of the World Health Organization (WHO) Safe Community model with respect to child injuries. STUDY DESIGN A population based quasiexperimental design was used. Cross sectional pre-implementation and post-implementation data were collected in intervention (Motala municipality) and control (Mjölby municipality) areas, both in Ostergötland county, Sweden. RESULTS The total relative risk of child injury in the intervention community decreased more (odds ratio 0.74; 95% confidence interval (CI) 0.68 to 0.81) than in a control community exposed only to national level injury prevention programs (0.93; 95% CI 0.82 to 1.05). The relative risk of moderately (abbreviated injury scale (AIS) 2) severe injury in the study area was reduced to almost a half (odds ratio 0.49; 95% Cl 0.41 to 0.57), whereas the risk of minor (AIS 1) injuries decreased only slightly (odds ratio 0.89; 95% CI 0.80 to 0.99). The risk of severe or fatal (AIS 3-6) injuries remained constant. CONCLUSIONS After introduction of an injury prevention program based on the WHO Safe Community model, the relative risk for child injury in the intervention community decreased significantly more than in a control community exposed only to national injury prevention programs.

Abstract
The aim of the study was to evaluate the outcome of a participatory community-based prevention program against injuries among the elderly. A population-based quasi-experimental design was used with pre- and post-implementation measurements in an intervention and a control area. The program was based on cross-sectoral participation in detecting and taking action against injuries among the elderly. Change in the relative risk of injury was estimated by the odds ratio. Morbidity in moderately (AIS 2) severe injury in the study area was reduced from 46 per 1000 population years to 25 per 1000 population years (odds ratio 0.55; 95% confidence interval 0.46-0.65), while the minor (AIS 1) injuries increased (odds ratio 1.55; 95% confidence interval 1.21-1.91). The risk of severe or fatal (AIS 3-6) injuries remained constant. In the study area, only a slight decrease in the total morbidity rate was observed (odds ratio 0.87; 95% confidence interval 0.77-0.99). In the control area, there was no evident change in the total morbidity rates. Falls decreased or showed a tendency to decrease in the age groups 65 to 79-y-old in the study area, while they increased in the older age group. The results indicate that no sharp boundaries should be drawn between safety education, physical conditioning, environmental adjustments and secondary prevention measures when planning safety promotion among the elderly. Future studies should address these issues along with the methodological complexity associated with assessment of participatory community-based safety promotion programs.

Abstract
The objective of the study was to examine the effect of a community-based injury prevention program on traffic injuries. A population-based quasi-experimental design was used with pre- and post-implementation measurements in an intervention and a control area. The program was based on inter-organizational participation in detecting and taking action against traffic injuries. The total relative risk for traffic injury in the study area showed only a tendency to decrease following program exposure (odds ratio 0.91; 95% confidence interval 0.81-1.02). No change in relative risk was observed in the control area. The analyses of program impact on injury severity showed that the relative risk for moderate injuries in the study area was reduced by almost half (odds ratio 0.59; 95% confidence interval 0.49-0.69), the risk for severe or fatal injuries remained constant (odds ratio 1.27; 95% confidence interval 0.80-2.02), and the risk for minor injuries increased (odds ratio 1.34; 95% confidence interval 1.13-1.59). The relative risk for moderate injuries was reduced by at least half for mopedists, cyclists, pedestrians, and those leaving or entering a motor vehicle. Community-based injury prevention can be a complement to national traffic safety programs.

Abstract
The objective in this study was to calculate costs and benefits caused by a safe community injury prevention programme in Motala, Sweden. The study design was a quasi-experimental evaluation involving an intervention population and a non-random control population. All injuries were recorded before and after an intervention programme. The presented calculations show that costs of injuries in a societal perspective decreased from 116 million Swedish Crowns (SEK) to 96 million SEK, while the cost for the intervention was estimated at approximately 10 million SEK. Thus, the safe community injury prevention programme in Motala should be judged as cost-effective.

Abstract
OBJECTIVES To study total costs, including direct costs (health care service, loss of personal property, medicine and transport) and indirect costs (loss of production or leisure) of dental trauma to children and adolescents with special reference to predictors. METHODS The study was based on a random sample of 192 children and adolescents with a dental trauma reported to an insurance company and prospectively followed up by telephone interviews over a period of 2 years. RESULTS On average, health care service costs represented 2,955 SEK (SD=3,818) and total costs 4,569 SEK (SD=3,053) for dental trauma to permanent teeth, and 837 SEK (SD=898) and 1,746 SEK (SD=1,183) for trauma to primary teeth. The most extensive type of indirect cost was loss of production or leisure, which averaged 1,286 SEK (SD=1,830) for injuries to permanent teeth and 699 SEK (SD=1,239) for injuries to primary teeth. Multiple regression analysis of demographic and dental injury variables showed that complicated trauma was of special importance to costs for permanent and primary teeth injuries. The average relative increase in total costs to patients and companions for complicated injury to permanent teeth was 140% (95% confidence interval [CI], 66-248%) for patients and 132% (95% CI, 54-249%) for companions. Lack of access to a dental clinic near the place of residence could increase the average total costs of injuries to permanent teeth by 91% for companions (95% CI, 20-204%) and for primary teeth by 134% (95% CI, 38-296%). CONCLUSIONS Dental traumas result in both direct and indirect costs, with a predominance of direct costs. The direct costs primarily depend on degree of severity, while indirect costs are mostly due to compromised access to health care service. Traumas to permanent teeth are especially costly and, due to additional maintenance, the care may continue for several years. This study has drawn attention to the significant implications of dental trauma to patient and companion, a new area where further studies are warranted.

Abstract
OBJECTIVE To evaluate a community based programme for evidence based prevention of injuries during physical exercise. DESIGN Quasi-experimental evaluation using an intervention population and a non-random control population. PARTICIPANTS Study municipality (population 41,000) and control municipality (population 26,000) in Sweden. MAIN OUTCOME MEASURES Morbidity rate for sports related injuries treated in the health care system; severity classification according to the abbreviated injury scale (AIS). RESULTS The total morbidity rate for sports related injuries in the study area decreased by 14% from 21 to 18 injuries per 1,000 population years (odds ratio 0.87; 95% confidence interval (CI) 0.79 to 0.96). No tendency towards a decrease was observed in people over 40. The rate of moderately severe injury (AIS 2) decreased to almost half (odds ratio 0.58; 95% CI 0.50 to 0.68), whereas the rate of minor injuries (AIS 1) increased (odds ratio 1.22; 95% CI 1.06 to 1.40). The risk of severe injuries (AIS 3-6) remained constant. The rate of total sports injury in the control area did not change (odds ratio 0.93; 95% CI 0.81 to 1.07), and the trends in the study and control areas were not statistically significantly different. CONCLUSION An evidence based prevention programme based on local safety rules and educational programmes can reduce the burden of injuries related to physical exercise in a community. Future studies need to look at adjusting the programme to benefit all age groups.

Abstract
This paper presents the concepts, ideas and techniques behind Case Based Reasoning (CBR) in relation to knowledge extraction techniques for health promotion. The ultimate goal is to develop a help-desk service for advice about preventive measures to be taken concerning concrete occupational injury hazards. CBR has been suggested to be a complimentary method to knowledge extraction in order to take direct advantages of large databases for building decision support systems. In this work a database on work injuries is being used to develop a CBR application using a CBR shell-called Recall.

Abstract
BACKGROUND Worldwide, an estimated 78 million people are disabled each year because of unintentional injuries and about 3 million die. The WHO Safe Community model is a framework for community-based injury prevention programmes. The aim of this study is to evaluate the outcome on health care utilization of a Safe Community programme. METHODS The incidence of injuries treated at health care facilities in an intervention municipality (pop. 41,000) was compared to the injury incidence in a control municipality (pop. 26,000). The incidence was recorded immediately before and one year after programme implementation from registrations made during all first-contact health care visits and from examination of hospital discharge registers. RESULTS The incidence of health care treated injuries in the intervention area had decreased by 13% (95% CI: 9-16%) from 119 (95% CI: 115-122) per 1000 population-years to 104 (95% CI: 101-107). In the control area, the corresponding injury incidences were 104 (95% CI: 100-108) and 106 (95% CI: 102-109). The hospital-treated injuries in the intervention area decreased by 15% (95% CI: 7-24%) from 19 (95% CI: 17-20) per 1000 population-years to 16 (95% CI: 15-17), while in the control area, the incidences remained at 13 (95% CI: 11-14) per 1000 population-years. Utilization of acute care in the intervention area for reasons other than injuries increased by 8% (95% CI: 6-10%), while in the control area, the number of visits did not show significant change. CONCLUSION This first controlled evaluation showed that an injury prevention programme based on local action groups can significantly reduce injuries requiring health care in a community. Local prevention can provide a complement to national level campaigns.

Abstract
Despite the fact that injuries consume a considerable amount of health care resources world-wide, 3.5 million people die from unintentional injuries each year. To handle this central public health problem, WHO has introduced the Safe Community accreditation for injury prevention programs. This study was to investigate the impact from a Safe Community program with regard to injury severity. Data were collected in Motala municipality (population = 41,000), Ostergötland county, Sweden, during one year before and one year after program intervention, from two sources: registration of trivial (AIS 1) and non-trivial (AIS 2-6) unintentional injuries from all acute care episodes in the area and recollection of hospital bed days from discharge registers. The incidence of non-trivial injuries treated in health care was found to have decreased by 41% (95% confidence interval, 37-45%), while the trivial injuries increased by 16% (9-22%). The larger decrease of non-trivial injuries was observed in all ages and injury event environments. The total number of bed days at emergency hospitals due to injuries decreased by 39% (37-41%) from 1983-84 to 1989, while the hospital bed utilization for other reasons decreased by 9% (8-9%). The study showed the implementation of a WHO Safe Community program led to the harm from unintentional injuries within the community being considerably more reduced than that of the injury incidence. In future assessments of injury prevention programs, classification of injury severity should be included to increase the validity of inter-program comparisons.

Abstract
OBJECTIVE To compare the efficiency of different machines for extracorporeal shock wave lithotripsy (ESWL) of renal stones and to analyze treatment strategies and stone characteristics as determinants of treatment failure. DESIGN Prospective cohort study. SETTING Nationwide study in Sweden. All 11 hospitals in Sweden using 1 of 7 lithotriptors in 1991 were included. PATIENTS The study cohort comprised 1171 (97.6%) of the 1200 patients in Sweden who underwent ESWL for the first time because of renal stones between February 18, 1991, and December 31, 1991. MAIN OUTCOME MEASURE Treatment failure, defined as 1 or more residual renal stone fragments larger than 4 mm 1 of 3 months after the end of treatment, was analyzed after ESWL monotherapy and after ESWL plus auxiliary treatment using a multivariate analysis. RESULTS Treatment failure varied by center from 12% to 48% (mean, 24%) after ESWL monotherapy and from 4% to 40% (mean, 18%) after ESWL plus auxiliary procedures. After adjusting for differences in the patient mix, the risk of treatment failure, measured as the odds ratio, varied by center almost 7-fold after ESWL monotherapy and 20-fold after ESWL plus auxiliary treatment. Substantial differences also existed for the same equipment used at different centers. The risk of treatment failure increased rapidly for renal stones larger than 15 mm, and it was at least 2-fold higher in patients who had multiple stones or a cavity. CONCLUSIONS When ESWL is used for the treatment of renal stones, the treatment policy has as great an effect on the success rate and need for auxiliary treatment as optimal equipment and proper patient selection. Meaningful comparisons of different lithotriptors require multivariate analyses with adjustment for patient selection.

Abstract
Exploratory studies in the Scandinavian countries have suggested that the national cost of unintentional injuries is equal to 4% of the Gross National Product (GNP). One way for Swedish society to handle this situation has been through community-based injury prevention programs. This study used action research methods to supplement the understanding of the community development for injury prevention. The aim of this paper is to present the participative model used in one of the first of these programs, the Motala Injury Prevention Program, and lessons learned from the first 10 years of its operation. The program 'succeeded' in 1993, when Motala Municipality formed a regular Safety Board chaired by the Municipal Commissioner. These are five main messages from the initial phases of the program: a community-based injury prevention program has to be regarded as a long-term project; preferably over more than a 10 year period, economic calculations are important in the community analysis phase of the program, inter-linkage between community organizations is essential in the design phase, the hand-over from the initial program developers to practitioners is critical in the implementation phase, it is important to maintain a high-quality data collection routine even after the conclusion of the community analysis phase of the program. These observations have a potential to be valid at least for Northern Europe, which, by comparison with other parts of the world is a relatively homogenous area with regard to external causes of injuries. Regarding other communities, there are known differences in injury rates and community organization.

Abstract
An open, prospective, randomized study was performed to investigate the effect of norfloxacin prophylaxis on stricture formation and operative outcome after transurethral resection of the prostate. After resection, the 359 patients studied were randomly divided into 2 groups: 1) those given norfloxacin as prophylaxis for 15 days following removal of the catheter (norfloxacin group) and 2) those given no antimicrobial prophylaxis during the same period (control group). Of the patients 94 were excluded. At followup 6 to 12 months postoperatively, the number of strictures in the anterior urethra was 2 of 135 in the norfloxacin group and 22 of 130 in the control group (p < 0.01). Strictures in the bladder neck developed in 3 of 135 and 4 of 130 patients, respectively (not significant). As a consequence of a lower structure incidence in the anterior urethra in the norfloxacin group, fewer patients in that group were dissatisfied with the operative outcome. The results suggest that norfloxacin provides effective prophylaxis against stricture formation after transurethral resection of the prostate.

Abstract
A prospective, randomized study was done to investigate the role of transurethral catheters in stricture formation after transurethral resection of the prostate. The operative outcome after using transurethral catheters made of 2 different materials compared with suprapubic catheters was also investigated. We studied 344 patients who underwent transurethral resection of the prostate. After resection the patients were randomly divided into 3 groups: 1) those drained by a transurethral polytetrafluoroethylene (Teflon)-coated latex catheter, 2) those drained by a transurethral polyvinylchloride catheter and 3) those drained by a suprapubic polyvinylchloride catheter. At 6 to 24 months the numbers of strictures in the anterior urethra were 10 of 102 and 11 of 102 in the transurethral drainage groups, respectively. The corresponding number of strictures in the suprapubic drainage group was 1 of 94 (p less than 0.01). Strictures in the bladder neck had developed in 5 of 102, 3 of 103 and 3 of 94 patients, respectively (not significant). As a consequence of a lower incidence of strictures in the anterior urethra in the suprapubic drainage group, more patients in that group were satisfied with the results of the operation.

Abstract
Urethral stricture is the most common late complication of transurethral prostatectomy (TURP). The cause is unknown. A prospective, randomised study was undertaken to investigate the role of the transurethral catheter in stricture formation. A total of 205 patients subjected to TURP were studied. Following resection, they were randomly divided into 2 groups: those drained by a transurethral siliconised latex catheter and those drained by a suprapubic siliconised latex catheter. At follow-up, 6 to 24 months later, 17% of the patients in the transurethral group had developed urethral stricture; the corresponding figure in the suprapubic group was 4%. As a consequence of the higher incidence of stricture in the transurethrally drained group, more patients in that group were dissatisfied with the results of the operation. It was concluded that the post-operative transurethral catheter was an important factor in stricture formation following TURP and that transurethral drainage with a siliconised latex catheter resulted in a higher incidence of stricture. This led to a greater number of patients being dissatisfied with the results of the operation, but the catheter did not affect the results in any other way.

Abstract
In an experiment with 12 calves, Aquacycline® in a 5 % (OTC-A5) and a 10 % (OTC-A10) solution, was compared with Terramycin®-100 (OTC-C) by injecting 20 mg OTC/kg bwt. of these preparations in the dewlap and monitoring serum concentrations as well as tissue reactions and residues at the site of injection. All 3 preparations resulted in oxytetracycline (OTC) serum concentrations above 0.5 µg/ml of approximately 60 h. During this period, OTC-A5 resulted in a 39 % and OTC-A10 in a 20 % larger area under the serum concentration-time curve, as compared to OTC-C (P < 0.05). The recorded tissue reaction in the form of swelling during the first week following injection of OTC-A5 averaged 72 % of that after OTC-C (P < 0.01), while the mean swelling after OTC-A10 was 81 % of the corresponding value after OTC-C (P < 0.05). The OTC residue levels at the sites of injection were lower after OTC-A5, but none of the preparations resulted in OTC residues exceeding 0.3 mg at 28 days and about 0.15 mg at 42 days after injection. The pathological changes at the site of injection were somewhat more pronounced in those calves which received OTC-C. Accordingly, these results give some support to the claims that Aquacycline® offers advantages with respect to absorption characteristics and tissue tolerance.
