An unsupervised classification method for inferring original case locations from low-resolution disease maps.
(73/272)
BACKGROUND: Widespread availability of geographic information systems software has facilitated the use of disease mapping in academia, government and private sector. Maps that display the address of affected patients are often exchanged in public forums, and published in peer-reviewed journal articles. As previously reported, a search of figure legends in five major medical journals found 19 articles from 1994-2004 that identify over 19,000 patient addresses. In this report, a method is presented to evaluate whether patient privacy is being breached in the publication of low-resolution disease maps. RESULTS: To demonstrate the effect, a hypothetical low-resolution map of geocoded patient addresses was created and the accuracy with which patient addresses can be resolved is described. Through georeferencing and unsupervised classification of the original image, the method precisely re-identified 26% (144/550) of the patient addresses from a presentation quality map and 79% (432/550) from a publication quality map. For the presentation quality map, 99.8% of the addresses were within 70 meters (approximately one city block length) of the predicted patient location, 51.6% of addresses were identified within five buildings, 70.7% within ten buildings and 93% within twenty buildings. For the publication quality map, all addresses were within 14 meters and 11 buildings of the predicted patient location. CONCLUSION: This study demonstrates that lowering the resolution of a map displaying geocoded patient addresses does not sufficiently protect patient addresses from re-identification. Guidelines to protect patient privacy, including those of medical journals, should reflect policies that ensure privacy protection when spatial data are displayed or published. (+info)
Medicare and Medicaid programs; hospital conditions of participation: patients' rights. Final rule.
(74/272)
This final rule finalizes the Patients' Rights Condition of Participation (CoP) which is applicable to all Medicare- and Medicaid-participating hospitals and contains standards that ensure minimum protections of each patient's physical and emotional health and safety. It responds to comments on the following standards presented in the July 2, 1999 interim final rule: Notice of rights; exercise of rights; privacy and safety; confidentiality of patient records; restraint for acute medical and surgical care; and seclusion and restraints for behavior management. As a result of comments received, we have revised the standards regarding restraint and seclusion and set forth standards regarding staff training and death reporting. (+info)
"There is such a thing as asking for trouble": taking rapid HIV testing to gay venues is fraught with challenges.
(75/272)
OBJECTIVES: To explore the feasibility and acceptability of offering rapid HIV testing to men who have sex with men in gay social venues. METHODS: Qualitative study with in-depth interviews and focus group discussions. Interview transcripts were analysed for recurrent themes. 24 respondents participated in the study. Six gay venue owners, four gay service users and one service provider took part in in-depth interviews. Focus groups were conducted with eight members of a rapid HIV testing clinic staff and five positive gay men. RESULTS: Respondents had strong concerns about confidentiality and privacy, and many felt that HIV testing was "too serious" an event to be undertaken in social venues. Many also voiced concerns about issues relating to post-test support and behaviour, and clinical standards. Venue owners also discussed the potential negative impact of HIV testing on social venues. CONCLUSION: There are currently substantial barriers to offering rapid HIV tests to men who have sex with men in social venues. Further work to enhance acceptability must consider ways of increasing the confidentiality and professionalism of testing services, designing appropriate pre-discussion and post-discussion protocols, evaluating different models of service delivery, and considering their cost-effectiveness in relation to existing services.

CARE+ user study: usability and attitudes towards a tablet pc computer counseling tool for HIV+ men and women.
(76/272)
CARE+ is a tablet PC-based computer counseling tool designed to support medication adherence and secondary HIV prevention for people living with HIV. Thirty HIV+ men and women participated in our user study to assess usability and attitudes towards CARE+. We observed them using CARE+ for the first time and conducted a semi-structured interview afterwards. Our findings suggest computer counseling may reduce social bias and encourage participants to answer questions honestly. Participants felt that discussing sensitive subjects with a computer instead of a person reduced feelings of embarrassment and being judged, and promoted privacy. Results also confirm that potential users think computers can provide helpful counseling, and that many also want human counseling interaction. Our study also revealed that tablet PC-based applications are usable by our population of mixed experience computer users. Computer counseling holds great potential for providing assessment and health promotion to individuals with chronic conditions such as HIV. (+info)
A proposed legal framework for addressing privacy for patient controlled health records in pediatrics.
(77/272)
Patient controlled health records(PCHRs) provide widespread and flexible access to integrated medical information. Unique legal challenges arise where the patient is a minor. Variations in laws and statutes concerning minor's rights to privacy and confidentiality, and institutions' local interpretations of them, need to be integrated in the principles governing PCHRs. We propose a legal framework to guide the development of access policies for PCHRs to ensure appropriate privacy and confidentiality protection surrounding minors. (+info)
Work, obesity, and occupational safety and health.
(78/272)
There is increasing evidence that obesity and overweight may be related, in part, to adverse work conditions. In particular, the risk of obesity may increase in high-demand, low-control work environments, and for those who work long hours. In addition, obesity may modify the risk for vibration-induced injury and certain occupational musculoskeletal disorders. We hypothesized that obesity may also be a co-risk factor for the development of occupational asthma and cardiovascular disease that and it may modify the worker's response to occupational stress, immune response to chemical exposures, and risk of disease from occupational neurotoxins. We developed 5 conceptual models of the interrelationship of work, obesity, and occupational safety and health and highlighted the ethical, legal, and social issues related to fuller consideration of obesity's role in occupational health and safety.

The creation of industry front groups: the tobacco industry and "get government off our back".
(79/272)
We investigated how industries use front groups to combat public health measures by analyzing tobacco industry documents, contemporaneous media reports, journal articles, and press releases regarding "Get Government Off Our Back," a coalition created by the tobacco industry. RJ Reynolds created Get Government Off Our Back in 1994 to fight federal regulation of tobacco. By keeping its involvement secret, RJ Reynolds was able to draw public and legislative support and to avoid the tobacco industry reputation for misrepresenting evidence. The tobacco industry is not unique in its creation of such groups. Research on organizational background and funding could identify other industry front groups. Those who seek to establish measures to protect public health should be prepared to counter the argument that government should not regulate private behavior. (+info)
There's no place like (a) home: ontological security among persons with serious mental illness in the United States.
(80/272)
As the homelessness 'crisis' in the United States enters a third decade, few are as adversely affected as persons with serious mental illness. Despite recent evidence favoring a 'housing first' approach, the dominant 'treatment first' approach persists in which individuals must climb a ladder of program requirements before becoming eligible for an apartment of their own. Drawing upon the concept of 'ontological security', this qualitative study examines the subjective meaning of 'home' among 39 persons who were part of a unique urban experiment that provided New York City's homeless mentally ill adults with immediate access to independent housing in the late 1990s. The study design involved purposively sampling from the experimental (housing first) group (N=21) and the control (treatment first) group (N=18) and conducting two life history interviews with each participant. Markers of ontological security-constancy, daily routines, privacy, and having a secure base for identity construction-provided sensitizing concepts for grounded theory analyses designed to also yield emergent, or new, themes. Findings revealed clear evidence of the markers of ontological security among participants living in their own apartments. This study expands upon previous research showing that homeless mentally ill persons are capable of independent living in the community. The emergent theme of 'what's next' questions and uncertainty about the future points to the need to address problems of stigma and social exclusion that extend beyond the minimal achievement of having a 'home'.
