Exploring factors associated with the uneven utilization of telemedicine in Norway: a mixed methods study.

BACKGROUND: Norway has a long history of using telemedicine, especially for geographical reasons. Despite the availability of promising telemedicine applications and the implementation of national initiatives and policies, the sustainability and scaling-up of telemedicine in the health system is still far from accomplished. The main objective of this study was to explore and identify the multi-level (micro, meso and macro) factors affecting telemedicine utilization in Norway. METHODS: We used a mixed methods approach. Data from a national registry were collected to analyze the use of outpatient visits and telemedicine contacts in Norway from 2009 to 2015. Interviews with key stakeholders at national, regional and local level helped complete and contextualize the data analysis and explore the main issues affecting the use of telemedicine by health authorities and hospitals. Relevant national documents were also used to support, contradict, contextualize or clarify information and data. RESULTS: Telemedicine use in Norway from 2009 to 2015 remained very low, not exceeding 0.5% of total outpatient activity at regional level and 0.1% at national level. All four regions used telemedicine. Of the 29 hospitals, 24 used it at least once over the 7-year period. Telemedicine was not used regularly everywhere, with some hospitals using it sporadically. Telemedicine was mostly used in selected specialties, including rehabilitation, neurosurgery, skin and venereal diseases. Three major themes affecting implementation and utilization of telemedicine in Norway emerged: (i) governance and strategy; (ii) organizational and professional dimensions; (iii) economic and financial dimensions. For each theme, a number of factors and challenges faced at different health care levels were identified. CONCLUSIONS: This study allowed shedding light on multi-level and interdependent factors affecting utilization of telemedicine in Norway. The identification of the main implementation and utilization challenges might support decision makers and practitioners in the successful scaling-up of telemedicine. This work provides a knowledge base useful to other countries which intend to implement telemedicine or other digital health services into their healthcare systems.

Evidence of soft dipole resonance in

The first conclusive evidence of a dipole resonance in ^{11}Li having isoscalar character observed from inelastic scattering with a novel solid deuteron target is reported. The experiment was performed at the newly commissioned IRIS facility at TRIUMF. The results show a resonance peak at an excitation energy of 1.03±0.03 MeV with a width of 0.51±0.11 MeV (FWHM). The angular distribution is consistent with a dipole excitation in the distorted-wave Born approximation framework. The observed resonance energy together with shell model calculations show the first signature that the monopole tensor interaction is important in ^{11}Li. The first ab initio calculations in the coupled cluster framework are also presented.

Selected melanocortin 1 receptor single-nucleotide polymorphisms differentially alter multiple signaling pathways.

The melanocortin 1 receptor (MC1R) is a highly polymorphic G protein-coupled receptor, which is known to modulate pigmentation and inflammation. In the current study, we investigated the pharmacological effects of select single-nucleotide polymorphisms (SNPs) (V60L, R163Q, and F196L). After transient expression of MC1Rs in human embryonic kidney 293 cells, basal and ligand-induced cAMP signaling and mitogen-activated protein kinase (MAPK) activation were assessed by using luciferase reporter gene assays and Western blot analysis, respectively. All receptor variants showed decreased basal cAMP activity. With the V60L and F196L variants, the decrease in constitutive activity was attributable, at least in part, to a reduction in surface expression. The F196L variant also displayed a significant reduction in potency for both the peptide agonist α-melanocyte-stimulating hormone (α-MSH) and the small-molecule agonist 1-[1-(3-methyl-L-histidyl-O-methyl-D-tyrosyl)-4-phenyl-4-piperidinyl]-1-butanone (BMS-470539). In MAPK signaling assays, the F196L variant showed decreased phospho-extracellular signal-regulated kinase levels after stimulation with either α-MSH or BMS-470539. In contrast, the R163Q variant displayed a selective loss of α-MSH-induced MAPK activation; whereas responsiveness to the small-molecule agonist BMS-470539 was preserved. Further assessment of MC1R variants in A549 cells, an in vitro model of inflammation, revealed an enhanced inflammatory response resulting from expression of the F196L variant (versus the wild-type MC1R). This alteration in function was restored by treatment with BMS-470539. Overall, these studies illustrate novel signaling profiles linked to distinct MC1R SNPs. Furthermore, our investigations highlight the potential for small-molecule drugs to rescue the function of MC1R variants that show reduced basal and/or α-MSH stimulated activity.

[Beyond benefit evaluation: Considering the unintended consequences of telehealth]. / Au-delà de l'évaluation des bénéfices : réflexion sur les conséquences inattendues de la télésanté.

Telehealth is seen as a key lever in health policy choices. However, many challenges remain in terms of its successful integration into clinical practices. To date, many telehealth initiatives are struggling to move beyond the pilot project stage. This is partly due to a culture of innovation that is mainly focused on the expected benefits of the technology and less on the changes and transformations it can generate. Telehealth is used in health care organizations with complex social dynamics, to say the least. Its introduction has unintended consequences that can affect patients, communities, professionals, organizations, health systems and society as a whole. The aim of this article is to discuss some of the unintended consequences of using telehealth in health care organizations and systems.

Lack of evidence for the dichotomy of TH1 and TH2 predominance in HIV-infected individuals.

A switch from a T helper 1 (TH1) cytokine phenotype to a TH2 phenotype has been proposed as a critical element in the progression of human immunodeficiency virus (HIV) disease. Here, constitutive cytokine expression was analyzed in unfractionated and sorted cell populations isolated from peripheral blood and lymph nodes of HIV-infected individuals at different stages of disease. Expression of interleukin-2 (IL-2) and IL-4 was barely detectable (or undetectable) regardless of the stage of disease. CD8+ cells expressed large amounts of interferon gamma and IL-10, and the levels of these cytokines remained stably high throughout the course of infection. Furthermore, similar patterns of cytokine expression were observed after stimulation in vitro of purified CD4+ T cell populations obtained from HIV-infected individuals at different stages of disease. These results indicate that a switch from the TH1 to the TH2 cytokine phenotype does not occur during the progression of HIV disease.

[Decentralized focus of the campaign against AIDS in Quebec]. / Enfoque descentralizado de la lucha contra el SIDA en Quebec.

The aim of this article is to describe the operation of a local health system within the social and public health context in the Province of Quebec, Canada. Following a review of the local health system concept, a description is given of the resources that have been used to combat acquired immunodeficiency syndrome (AIDS) in the city of Quebec and the surrounding region. Some of the results obtained and difficulties encountered are presented, as are prospects for this work in the future.

Age-related decrease of dehydroepiandrosterone concentrations in low density lipoproteins and its role in the susceptibility of low density lipoproteins to lipid peroxidation.

The incidence of atherosclerosis and related diseases increases with age. The aging process may enhance lipoprotein modification, which leads to an increase in the susceptibility of low density lipoprotein (LDL) and high density lipoprotein (HDL) to oxidation. Dehydroepiandrosterone (DHEA), the most abundant steroid hormone in humans, has been shown to have antiatherogenic effects. This hormone also decreases dramatically with age. In the present study, we were interested in determining the presence of DHEA/DHEAS (dehydroepiandrosterone sulfate) and changes in their concentrations in HDL and LDL lipoproteins with age. Moreover, we studied the susceptibility of LDL to oxidation with age in the presence or absence of vitamin E or DHEA. We demonstrated that vitamin E is unable to restore the decreased resistance to oxidation of LDL from elderly subjects to that of LDL obtained from young subjects. Furthermore, our results provide evidence that DHEA is an integral part of LDL and HDL and disappears to almost nondetectable levels during aging. The DHEA incorporated into the LDL from elderly subjects increased LDL resistance to oxidation in a concentration-dependent manner. The increased resistance provided by DHEA was higher than that with vitamin E. DHEA seems to act either by protecting vitamin E from disappearance from LDL under oxidation or by scavenging directly the free radicals produced during the oxidative process. Our results suggests that DHEA exerts an antioxidative effect on LDL, which could have antiatherogenic consequences. Careful clinical trials of DHEA replacement should determine whether this ex vivo effect could be translated into any measurable antiatherogenic (cardioprotective) action.

[An effective intervention project for arterial hypertension screening in family medicine]. / Un projet d'intervention efficace pour le dépistage de l'hypertension artérielle en médecine familiale.

This study was carried out to assess the effectiveness of a preventive protocol in improving hypertension detection in a hospital-based family medicine unit. This protocol was planned and implemented by local practitioners and did not need any additional budgeting. Two distinct groups, each of 850 adults, were randomly selected from patients having consulted before and after the introduction of the protocol. Medical records were audited. Hypertension screening rate improved of 17.7% (p less than 0.00001) after the application of the preventive intervention. Furthermore, a 20.5% increase of the screening rate was estimated after adjustment by the logistic regression method, for characteristics related to patients and to practitioners. In conclusion, these findings support the hypothesis that this preventive protocol contributes to improve in family physicians their hypertension screening performance and they justify further assessment with a control group.

Can a patient smart card improve decision making in a clinical setting?.

In the health field, clinical information is the raw material for the clinician delivering health services. Therefore, the clinical information available to the physician is often incomplete or even non¿existent upon consultation. Furthermore, the reconstruction of the medical history, which is the most important source of data for the clinician to establish a diagnosis and initiate a treatment, suffers from many constraints. The smart card, like the one used in Quebec's project, could ease the physician's decision-making by allowing fast access to accurate and pertinent data. The smart card is a major asset in the present health system.

Médicarte software developed for the Quebec microprocessor health card project.

The Quebec Patient Smart Card Project is a Provincial Government initiative under the responsibility of the Rgie de l'assurance-maladie du Québec (Quebec Health Insurance Board). Development, implementation, and assessment duties were assigned to a team from Université Laval, which in turn joined a group from the Direction de la santé publique du Bas-St-Laurent in Rimouski, where the experiment is taking place. The pilot project seeks to evaluate the use and acceptance of a microprocessor card as a way to improve the exchange of clinical information between card users and various health professionals. The card can be best described as a résumé containing information pertinent to an individual's health history. It is not a complete medical file; rather, it is a summary to be used as a starting point for a discussion between health professionals and patients. The target population is composed of persons 60 years and over, pregnant women, infants under 18 months, and the residents of a small town located in the target area, St-Fabien, regardless of age. The health professionals involved are general practitioners, specialists, pharmacists, nurses, and ambulance personnel. Participation in the project is on a voluntary basis. Each health care provider participating in the project has a personal identification number (PIN) and must use both an access card and a user card to access information. This prevents unauthorized access to a patient's card and allows the staff to sign and date information entered onto the patient card. To test the microprocessor card, we developed software based on a problem-oriented approach integrating diagnosis, investigations, treatments, and referrals. This software is not an expert system that constrains the clinician to a particular decisional algorithm. Instead, the software supports the physician in decision making. The software was developed with a graphical interface (Windows 3.1) to maximize its user friendliness. A version of the software was developed for each of the four groups of health care providers involved. In addition we designed an application to interface with existing pharmaceutical software. For practical reasons and to make it possible to differentiate between the different access profiles, the information stored on the card is divided in several blocks: Identification, Emergency, History (personal and family), Screening Tests, Vaccinations, Drug Profile, General follow-up, and some Specific follow-ups (Pregnancy, Ophthalmology, Kidney failure, Cardiology, Pediatrics, Diabetes, Pneumology, Specific parameters). Over 14,000 diagnoses and symptoms are classified with four levels of precision, the codification being based on the ICPC (International Classification for Primary Care). The software contains different applications to assist the clinician in decision making. A "Drug Advisor" helps the prescriber by detecting possible interactions between drugs, giving indications (doses) and contraindications, cautions, potential side-effects and therapeutic alternatives. There is also a prevention module providing recommendations for vaccination and periodic examinations based on the patient's age and sex. The pharmaceutical, vaccination, and screening tests data banks are updated every six months. These sections of the software are accessible to access card holders at any times, even without a patient card, and constitute in themselves an interesting clinical tool. We developed a software server (SCAM) allowing the different applications to access the data in a memory card regardless of the type of memory card used. Using a single high level command language, this server provides a standardized utilization of memory cards from various manufacturers. It ensures the compatibility of the applications using the card as a storage medium. (abstract truncated)

Effectiveness of a program to improve hypertension screening in primary care.

OBJECTIVE: To evaluate the effectiveness of a program to improve hypertension screening practices in primary care. DESIGN: Retrospective quasi-experimental study. SETTING: Two hospital-based family medicine centres (FMCs). PATIENTS: In the study FMC, two study groups of randomly selected adult patients: 425 who visited the FMC before implementation of the screening improvement program (from Apr. 1, 1983, to Mar. 31, 1984) and 418 who visited it afterward (from Apr. 1, 1986, to Mar. 31, 1987). These patients were matched with 392 and 442 control patients respectively seen during the same time frames at the second FMC. INTERVENTIONS: Educational sessions for physicians to standardize blood pressure measurement and knowledge of the recommendations from the Canadian Hypertension Society on hypertension screening and diagnosis, and specific operational incentives to improve hypertension screening, including a reference guide placed in each physician's office, a coloured form for recording blood pressure measurements placed in every patient's chart and a follow-up and recall card file. MAIN OUTCOME MEASURE: Frequency of blood pressure measurements recorded in patient charts. RESULTS: The hypertension screening rate was 60% per year in the study group before program implementation and 79% in the study group afterward; the corresponding rates in the two control groups were 72% and 59% (p < 0.0001). Patients were more likely to be screened if they visited the physician for a periodic health examination than for other problems (e.g., psychosocial or dermatologic) and if they had a scheduled appointment rather than no appointment. Physician characteristics that were positive predictors of screening were low age, female sex and payment on a salary basis. CONCLUSION: Physician education and incentives are effective in improving hypertension screening practices in hospital-based FMCs without incurring additional costs or other use of resources. Further evaluation of such a program should be undertaken in other primary care settings.

A microprocessor card software server to support the Quebec health microprocessor card project.

The Quebec Health Smart Card Project is advocating the use of a memory card software server[1] (SCAM) to implement a portable medical record (PMR) on a smart card. The PMR is viewed as an object that can be manipulated by SCAM's services. In fact, we can talk about a pseudo-object-oriented approach. This software architecture provides a flexible and evolutive way to manage and optimize the PMR. SCAM is a generic software server; it can manage smart cards as well as optical (laser) cards or other types of memory cards. But, in the specific case of the Quebec Health Card Project, SCAM is used to provide services between physicians' or pharmacists' software and IBM smart card technology. We propose to expose the concepts and techniques used to provide a generic environment to deal with smart cards (and more generally with memory cards), to obtain a dynamic an evolutive PMR, to raise the system global security level and the data integrity, to optimize significantly the management of the PMR, and to provide statistic information about the use of the PMR.
