BackgroundSelf-management of asthma may improve asthma outcomes. The Internet has been suggested as a tool for the monitoring and self-management of asthma. However, in a recent study we found that a Web interface had some disadvantages and that users stopped using the application after a short while.ObjectiveThe primary objective of this study was to evaluate, from a user perspective, the feasibility of using short message service (SMS) for asthma diary data collection through mobile phones. The secondary objective was to investigate patient compliance with an SMS diary, as measured by response rates over time.MethodsThe study included quantitative response rate data, based on SMS collection, and qualitative data from a traditional focus group setting. In a period of 2 months, the participants received 4 SMS messages each day, including a medication reminder, a request to enter peak flow, data on sleep loss, and medication dosage. Participants were asked to reply to a minimum of 3 of the messages per day. Diary inputs were collected in a database and the response rate per patient was expressed as the number of diary inputs (SMS replies) divided by diary requests (product of number of days in the study and the number of diary questions per day) for each participant. After the study period, the participants were invited to a focus group interview addressing the participants' attitudes to their disease, their experience with the SMS asthma diary, and their future expectations from the SMS asthma diary.ResultsTwelve patients with asthma (6 males, 6 females) participated in the data collection study. The median age was 38.5 (range: 13 – 57) years. The median response rate per patient was 0.69 (range: 0.03 – 0.98), ie, half the participants reported more than about two thirds of the requested diary data. Furthermore, response rates were relatively steady during the study period with no signs of decreasing usage over time. From the subsequent focus group interview with 9 users we learned that, in general, the participants were enthusiastic about the SMS diary – it became an integrated part of their everyday life. However, the participants wished for a simpler diary with only one SMS message to respond to and a system with a Web interface for system customization and graphical display of diary data history.ConclusionThis study suggests that SMS collection of asthma diary data is feasible, and that SMS may be a tool for supporting the self-management of asthma (and possibly other chronic diseases) in motivated and self-efficacious patients because mobile phones are a part of people's everyday lives and enable active requests for data wherever the patient is. The combination of SMS data collection and a traditional Web page for data display and system customization may be a better and more usable tool for patients than the use of Web-based asthma diaries which suffer from high attrition rates.

The aim of this review was to systemically explore the current evidence regarding patient-related barriers to cancer pain management to find new areas that might be important for better understanding of patient barriers' phenomenon. The method used in this study was a computerised literature search, carried out in Cochrane Library, Medline (through PubMed), Web of Science and EMBASE databases for the period 1994-2005. Thirty-seven studies, dealing with cognitive, sensory and affective patient-related barriers, as well as studies, describing patients' pain communication and their adherence to analgesic regimen were included and analysed. The dominant part of articles studied cognitive patient-related barriers to cancer pain management, while affective, sensory barriers, as well as pain communication and pain medication adherence were studied in much less extend. However, the findings from different studies regarding relationships between cognitive barriers and pain intensity were not consistent. On the contrary, the quality of pain communication was consistently found to be not satisfactory in some key areas. The associations between more expressed attitudinal as well as sensory barriers and less optimal adherence were also consistent. In conclusions suggestion for the new research areas on patient-related barriers to cancer pain management are made. Firstly, further research is needed to differentiate the role of cognitive, affective and sensory factors with respect to their impact on pain relief, pain communication and medication adherence. Besides that, validated instruments to assess patients' pain communication and adherence to analgesic regimen are lacking.

Patient-, physician-, and health care system-related barriers of cancer pain management in patients with malignant diseases are a recognized and widely investigated issue. The purpose of this review is to summarize the main findings of empirical research on these barriers in the literature. The most significant patientrelated barriers were patient reluctance to report pain and adhere to treatment recommendations. Besides that, cognitive, affective, and sensory patient-related barriers to cancer pain management with opioid analgesics have been studied using quantitative and qualitative research methods. The Barriers Questionnaire and its shortened and modified versions were the most commonly used instruments in the context of research on patient-related barriers to cancer pain management. The most prominent physicianrelated barriers were insufficient physicians’ knowledge about cancer pain management, inadequate patterns of pain assessment, and inadequate opioid prescription. The methodologies used to conduct the majority of the studies on physician-related barriers were weak. Nevertheless, physician knowledge of pain management guidelines, the quality of pain assessment and opioid prescription have been shown to be obviously better in a few Western countries. Institutional and health care system-related barriers were relevant only in countries with restrictive opioid prescription regulations. The evaluation of the influence of cultural-social-economical background on cancer pain management could probably help to obtain better insight into the problems of unrelieved cancer pain.

Background: Inspired by diffusion research, this paper examines how perceived need, health status, experiences with medicine and testing, consumption of mass media and sociodemography influence the public’s familiarity, knowledge, attitudes and intentions regarding pharmacogenetics. The objective is to identify factors affecting the adoption pattern of pharmacogenetics in the public. Method: The paper is based on an Internet-based questionnaire survey conducted in March 2005. A total of 3,000 representative Danes aged 18–70 years were included in the survey, representing a response rate of 58.9%. Results/Conclusion: Knowledge of pharmacogenetics, and thus the diffusion of the technology, is influenced by medicine consumption, experienced lack of effect and side effects, use of medical testing and perception of societal need. Increased knowledge is seen in all cases. The general perception of and attitude to pharmacogenetics is related to prior use of medical tests and perception of societal need for pharmacogenetics, which in both cases indicates an increased positive approach.

Objective: My aim was to examine the ethical, social and legal implications of pharmacogenomics. Method: I performed a critical review of the literature. The primary focal point is the bioethical principle discussed. The second outcome measure is the perspective of the discussion. Results: This review documents that the pharmacogenomics issues of concern are comparable to issues concerning other genetic developments in general. However, two main issues are particular to the case of pharmacogenomics. Firstly, this review reveals that society, industry, groups and individuals appreciate the prospect of pharmacogenomics very differently. Secondly, there is a lack of research into the post-marketing implications of pharmacogenomics. Conclusion: An extensive focus on the ethical, social and legal implications of pharmacogenomics, in terms of both pre- as well as post-marketing issues, is essential. Also, a multidisciplinary approach which includes individual and group opinions in an upfront manner in the research and development process is essential. Otherwise, there is a substantial risk that the positive prospects of pharmacogenomics will not survive due to fear and a lack of acceptance and understanding on the part of the general public.
