Reengineering the picture archiving and communication system (PACS) process for digital imaging networks PACS.
(9/388)
Prior to June 1997, military picture archiving and communications systems (PACS) were planned, procured, and installed with key decisions on the system, equipment, and even funding sources made through a research and development office called Medical Diagnostic Imaging Systems (MDIS). Beginning in June 1997, the Joint Imaging Technology Project Office (JITPO) initiated a collaborative and consultative process for planning and implementing PACS into military treatment facilities through a new Department of Defense (DoD) contract vehicle called digital imaging networks (DIN)-PACS. The JITPO reengineered this process incorporating multiple organizations and politics. The reengineered PACS process administered through the JITPO transformed the decision process and accountability from a single office to a consultative method that increased end-user knowledge, responsibility, and ownership in PACS. The JITPO continues to provide information and services that assist multiple groups and users in rendering PACS planning and implementation decisions. Local site project managers are involved from the outset and this end-user collaboration has made the sometimes difficult transition to PACS an easier and more acceptable process for all involved. Corporately, this process saved DoD sites millions by having PACS plans developed within the government and proposed to vendors second, and then having vendors respond specifically to those plans. The integrity and efficiency of the process have reduced the opportunity for implementing nonstandard systems while sharing resources and reducing wasted government dollars. This presentation will describe the chronology of changes, encountered obstacles, and lessons learned within the reengineering of the PACS process for DIN-PACS. (+info)
Are risk factors for atherothrombotic disease associated with back pain sickness absence? The Whitehall II Study.
(10/388)
STUDY OBJECTIVE: To explore the previously stated hypothesis that risk factors for atherothrombotic disease are associated with back pain. DESIGN: Prospective (mean of four years of follow up) and retrospective analyses using two main outcome measures: (a) short (< or = 7 days) and long (> 7 days) spells of sickness absence because of back pain reported separately in men and women; (b) consistency of effect across the resulting four duration of spell and sex cells. SETTING: 14 civil service departments in London. PARTICIPANTS: 3506 male and 1380 female white office-based civil servants, aged 35-55 years at baseline. MAIN RESULTS: In age adjusted models, low apo AI was associated with back pain across all four duration-sex cells and smoking was associated across three cells. Six factors were associated with back pain in two cells: low exercise and high BMI, waist-hip ratio, triglycerides, insulin and Lp(a). On full adjustment (for age, BMI, employment grade and back pain at baseline), each of these factors retained a statistically significant effect in at least one duration-sex cell. Triglycerides were associated with short and long spells of sickness absence because of back pain in men in fully adjusted models with rate ratios (95% confidence intervals) of 1.53 (1.1, 2.1) and 1.75 (1.0, 3.2) respectively. There was little or no evidence of association in age adjusted models with: fibrinogen, glucose tolerance, total cholesterol, apoB, hypertension, factor VII, von Willebrand factor, electrocardiographic evidence of coronary heart disease and reported angina. CONCLUSIONS: In this population of office workers, only modest support was found for an atherothrombotic component to back pain sickness absence. However, the young age of participants at baseline and the lack of distinction between different types of back pain are likely to bias the findings toward null. Further research is required to ascertain whether a population sub-group of atherothrombotic back pain can be identified. (+info)
Challenges in changing to non-chlorofluorocarbon inhalers in the treatment of asthma.
(11/388)
The chlorofluorocarbon (CFC)-based metered dose inhaler, which has been the mainstay of the management of obstructive lung diseases, will soon be phased out world wide and replaced by CFC-free devices. Patients will have to be changed to the devices in a co-ordinated manner to avoid any risk to their health and safety. The different shapes and aerosol delivery characteristics of the new inhalers, as well as their distinctive taste, could add to the levels of poor drug use already experienced in asthma. From previous change scenarios in disease management, the potential for unstable asthma control is a real possibility with all the attendant costs. By using the time available before CFC-based inhalers are withdrawn, there is an opportunity to enhance asthma management during this period of change. (+info)
Variations in self-reported health by occupational grade in the British Post Office: the Q-health project.
(12/388)
Between 1995 and 1998 a national sample of 58,501 (42,885 males, 15,616 females) Post Office employees (29%) completed and returned a postal questionnaire survey providing information on demographic characteristics, physical and psychological health, health and lifestyles and health screening behaviour. Response rates by occupational grade were as follows: manual (male 69.3%, females 43.6%); clerical (male = 11.8%, female, 42.3%); middle management (males 15.5%, females 10.7%) and senior management (males 3.4%, females 3.3%). A number of differences in health status occurred with occupational grade. Angina, high blood pressure, obesity, smoking, arthritis, disability, GP consultations and abnormal smears were all more prevalent in lower occupational grades. Height, job satisfaction, seat belt use and breast self-examination were also lower in lower status jobs. Some findings were unexpected: GHQ scores indicated better mental health in lower grades, whilst knowledge and frequency of testicular self-examination and attendance for mammograms were higher in lower grades. Self-reports for asthma, diabetes and family history of bowel cancer were also greater in higher grades. These findings are considered in terms of response bias, health selection, the psychosocial work environment, occupational health interventions and the nature, meaning and organization of social position within the Post Office.

Prescription drugs and managed care: can 'free-market detente' hold?
(13/388)
The rapid rise in pharmaceutical benefits costs, often cited as a major contributor to the resurgence in health care cost growth, is beginning to strain the relationship between the pharmaceutical and the managed care industries in the United States. In interviews conducted in 1999, executives from both industries maintained a continued preference for a market-based resolution of these tensions. There is evidence, however, that this private-sector detente may give way in the face of the rising business and political pressures that both industries face. Active leadership will be required to prevent deterioration of the prevailing political climate toward economic controls. (+info)
Excess mortality from avoidable and non-avoidable causes in men of low socioeconomic status: a prospective study in Korea.
(14/388)
STUDY OBJECTIVE: The objective of this study was to evaluate the magnitude and contributory factors of socioeconomic differentials in mortality in a cohort of Korean male civil servants. DESIGN: A prospective observational study of male civil servants followed up for five years after baseline measurement. SETTING: All civil service offices in Korea. PARTICIPANTS AND MEASUREMENTS: The study was conducted on 759,665 Korean male public servants aged 30-64 at baseline examination in 1992. The grade of monthly salary of these participants divided into four groups, a proxy indicator of socioeconomic status (SES), was the main predictive variable. Mortality of the participants was followed up from 1992 to 1996. The causes of deaths were categorised into four groups according to the medical amenability: avoidable, partly avoidable, non-avoidable, and external causes of death. The risk of mortality associated with SES was estimated using the Cox proportional hazard model. MAIN RESULTS: Lowest SES group had significantly higher risk of mortality from most causes compared with the highest SES group in the order of external cause (relative risk (RR): 2.26), avoidable (RR: 1.65), all cause (RR: 1.59), and non-avoidable mortality (RR: 1.54). With the adjustment of known risk factors, significantly higher risks of mortality in lowest SES group were attenuated but persisted. Looking at the deaths from partly avoidable causes, significantly higher risks of mortality in the lowest SES group was observed from cerebrovascular disease but not from coronary heart disease. CONCLUSIONS: Socioeconomic differentials in non-avoidable as well as avoidable mortality, persisting even under the control of risk factors, suggest that mortality is influenced not only by the quality of health care and different distribution of risk factors but also by other aspects of SES that are yet unknown.

Employment grade differences in cause specific mortality. A 25 year follow up of civil servants from the first Whitehall study.
(15/388)
STUDY OBJECTIVE: To test the hypothesis that the association between socioeconomic status and mortality rates cuts across the major causes of death for middle aged and elderly men. DESIGN: 25 year follow up of mortality in relation to employment grade. SETTING: The first Whitehall study. PARTICIPANTS: 18,001 male civil servants aged 40-69 years who attended the initial screening between 1967 and 1970 and were followed up for at least 25 years. MAIN OUTCOME MEASURE: Specific causes of death. RESULTS: After more than 25 years of follow up of civil servants, aged 40-69 years at entry to the study, employment grade differences still exist in total mortality and for nearly all specific causes of death. Main risk factors (cholesterol, smoking, systolic blood pressure, glucose intolerance and diabetes) could only explain one third of this gradient. Comparing the older retired group with the younger pre-retirement group, the differentials in mortality remained but were less pronounced. The largest decline was seen for chronic bronchitis, gastrointestinal diseases and genitourinary diseases. CONCLUSIONS: Differentials in mortality persist at older ages for almost all causes of death. (+info)
Psychological morbidity in general practice managers: a descriptive and explanatory study.
(16/388)
BACKGROUND: Proposals to establish an occupational health service for primary care should be informed by knowledge of the health needs of general practice employees. AIM: To determine the prevalence and occupational correlates of stress, anxiety, and depression among practice managers in two contrasting health authorities in England. METHOD: A postal questionnaire, soliciting information about stress induced by work-related activities, which contained the General Health Questionnaire (GHQ) and Hospital Anxiety and Depression Scale (HADS), was sent to all 149 practice managers in two health authorities areas of south-east England. RESULTS: Completed questionnaires were returned by 111 (75%) managers; 41/111 (37%) achieved GHQ case status with scores on HADS indicating that 49/111 (44%) classified themselves as anxious and 19/111 (17%) as depressed. The likelihood of being a case was found to be higher in managers from practices with larger numbers of GP partners (P = 0.02) and in managers from practices not in receipt of deprivation payments (P = 0.03). Multiple logistic regression showed that managers' perceived difficulties with general practice administration duties (relative ratio [RR] = 3.27, 95% confidence interval [CI] = 1.22-8.75) and dealings with GPs (RR = 1.86, 95% CI = 1.03-3.34) were the most powerful predictors of case status. CONCLUSION: The questionnaire uncovered high prevalences of self-reported stress, anxiety, and depression in general practice managers. Although the vast majority of National Health Service (NHS) employees have access to an occupational health service, no such source of support exists for those working in general practice. The NHS needs to establish an occupational health service that caters to the needs of clinical and non-clinical members of primary health care teams. (+info)
