Medication misuse results in considerable problems for both patient and society. It is a complex problem with many contributing factors, including timely access to product information.
To investigate the value of 3-dimensional (3D) visualization paired with video conferencing as a tool for pharmaceutical advice over distance in terms of accessibility and ease of use for the advice seeker.
We created a Web-based communication service called AssistancePlus that allows an advisor to demonstrate the physical handling of a complex pharmaceutical product to an advice seeker with the aid of 3D visualization and audio/video conferencing. AssistancePlus was tested in 2 separate user studies performed in a usability lab, under realistic settings and emulating a real usage situation. In the first study, 10 pharmacy students were assisted by 2 advisors from the Swedish National Co-operation of Pharmacies' call centre on the use of an asthma inhaler. The student-advisor interview sessions were filmed on video to qualitatively explore their experience of giving and receiving advice with the aid of 3D visualization. In the second study, 3 advisors from the same call centre instructed 23 participants recruited from the general public on the use of 2 products: (1) an insulin injection pen, and (2) a growth hormone injection syringe. First, participants received advice on one product in an audio-recorded telephone call and for the other product in a video-recorded AssistancePlus session (product order balanced). In conjunction with the AssistancePlus session, participants answered a questionnaire regarding accessibility, perceived expressiveness, and general usefulness of 3D visualization for advice-giving over distance compared with the telephone and were given a short interview focusing on their experience of the 3D features.
In both studies, participants found the AssistancePlus service helpful in providing clear and exact instructions. In the second study, directly comparing AssistancePlus and the telephone, AssistancePlus was judged positively for ease of communication (P = .001), personal contact (P = .001), explanatory power (P

An out-patient service for patients suffering from amyotrophic lateral sclerosis (ALS), the ALS-clinic, was established at the Department of Neurology, Haukeland Hospital, in 1990. The number of ALS patients who were hospitalised during the period 1990-1995 was 59, with a mean stay in hospital of 14.8 days. Eleven of the patients died in hospital. The ALS-clinic had 127 consultations during the same period, with a mean of 2.2 consultations per patient. Speech difficulties were the dominating problem at 26 of the consultations. 32 patients experienced feeding difficulties, and a percutaneous endoscopic gastrostomy was performed in nine cases. Respiratory problems dominated in ten patients, but only two of these patients wanted a home ventilator. Various assistive devices were adapted for 16 patients.
The treatment-mix, treatment time, and dental status of 268 male industrial workers entitled to employer-provided dental care were studied. The data were collected from treatment records of the covered workers over the 5-year period 1989-93. Treatment time was based on clinical treatment time recorded per patient visit, and the treatment procedure codes were reclassified into a treatment-mix according to American Dental Association categories, with a modification combining endodontics and restorative treatment. The mean number of check-ups followed by prescribed treatment (treatment courses) during the 5 years was 3.7 among those who had entered the in-house dental care program prior to the monitored period (old attenders). Their treatment time was stable, 57-63 min per year, while the first-year mean treatment time (170 min) of those who had entered the program during the study period (new attenders) was significantly higher (P
In the current climate of budgetary restraint in the health care system, cost effectiveness is a concept which surfaces with increasing frequency, especially in reference to health care services funded by government. Since significant elements of pharmacy services in Canada are thus funded (including in most provinces, hospital pharmacy services, and prescription drug plans for senior citizens), it is important that pharmacy "tune into" the concept, and recognize it as an essential criterion to be met in the maintenance of existing services and in the development of new services. Prerequisite to a consideration of cost effectiveness is, of course, consideration of effectiveness; and a statement about the effectiveness; and a statement about the effectiveness of a service implies a potential for measurement of effect or outcome. In the 1980s, as pharmacy focuses its efforts on patients rather than products, that effect must surely be defined in "people" terms. One of the important dimensions of today's patient-focussed pharmacy services is patient counselling, more broadly, patient education.
The 2005 Canadian Hypertension Education Program recommendations for the management of hypertension: part 1- blood pressure measurement, diagnosis and assessment of risk.
To provide updated, evidence-based recommendations for the diagnosis and assessment of adults with high blood pressure (BP).
For persons in whom a high BP value is recorded, the assignment of a diagnosis of hypertension is dependent on the appropriate measurement of BP, the level of the BP elevation and the duration of follow-up. In addition, the presence of cardiovascular risk factors and target organ damage should be assessed to determine the urgency, intensity and type of treatment. For persons diagnosed as having hypertension, estimating overall risk of adverse cardiovascular outcomes requires an assessment of other vascular risk factors and hypertensive target organ damage.
MEDLINE searches were conducted from November 2003 to October 2004 to update the 2004 recommendations. Reference lists were scanned, experts were polled, and the personal files of the authors and subgroup members were used to identify other studies. Identified articles were reviewed and appraised using prespecified levels of evidence by content and methodological experts. As per previous years, only studies that had been published in the peer-reviewed literature were included; evidence from abstracts, conference presentations and unpublished personal communications was not included.
This document contains recommendations for BP measurement, diagnosis of hypertension and assessment of cardiovascular risk for adults with high BP. These include the accurate measurement of BP, criteria for diagnosis of hypertension, and recommendations for follow-up, assessment of overall cardiovascular risk, routine and optional laboratory testing, assessment for renovascular and endocrine causes, home and ambulatory BP monitoring, and the role of echocardiography for those with hypertension. Key features of the 2005 recommendations include an expedited diagnostic algorithm for hypertension and an endorsement of the use of home/self and ambulatory BP assessment as validated techniques in establishing the diagnosis of hypertension.
All recommendations were graded according to the strength of the evidence and voted on by the 43 members of the Canadian Hypertension Education Program Evidence-Based Recommendations Task Force. All recommendations reported in the present paper received at least 95% consensus. These guidelines will continue to be updated annually.
To provide updated, evidence-based recommendations for the management of hypertension in adults.
For lifestyle and pharmacological interventions, evidence from randomized controlled trials and systematic reviews of trials was preferentially reviewed. While changes in cardiovascular morbidity and mortality were the primary outcomes of interest, for lifestyle interventions, blood pressure lowering was accepted as a primary outcome given the lack of long-term morbidity/mortality data in this field, and for certain comorbid conditions, other relevant outcomes, such as development of proteinuria or worsening of kidney function, were considered.
MEDLINE searches were conducted from November 2003 to October 2004 to update the 2004 recommendations. Reference lists were scanned, experts were contacted, and the personal files of the subgroup members and authors were used to identify additional published studies. All relevant articles were reviewed and appraised independently, using prespecified levels of evidence, by content and methodology experts. As per previous years, only studies that had been published in the peer-reviewed literature were included; evidence from abstracts, conference presentations and unpublished personal communications was not included.
Lifestyle modifications to prevent and/or treat hypertension include the following: perform 30 min to 60 min of aerobic exercise on four to seven days of the week; maintain a healthy body weight (body mass index of 18.5 kg/m2 to 24.9 kg/m2) and waist circumference (less than 102 cm for men and less than 88 cm for women); limit alcohol consumption to no more than 14 units per week in men or nine units per week in women; follow a reduced fat, low cholesterol diet with an adequate intake of potassium, magnesium and calcium; restrict salt intake; and consider stress management (in selected individuals). Treatment thresholds and targets should take into account each individual's global atherosclerotic risk, target organ damage and any comorbid conditions. Blood pressure should be lowered to 140/90 mmHg or less in all patients, and to 130/80 mmHg or less in those with diabetes mellitus or chronic kidney disease. Most adults with hypertension require more than one agent to achieve target blood pressures. For adults without compelling indications for other agents, initial therapy should include thiazide diuretics. Other agents appropriate for first-line therapy for diastolic hypertension with or without systolic hypertension include beta-blockers (in those younger than 60 years), angiotensin-converting enzyme (ACE) inhibitors (except in black patients), long-acting calcium channel blockers and angiotensin receptor antagonists. Other agents appropriate for first-line therapy for isolated systolic hypertension include long-acting dihydropyridine calcium channel blockers and angiotensin receptor antagonists. Certain comorbid conditions provide compelling indications for first-line use of other agents: in patients with angina, recent myocardial infarction or heart failure, beta-blockers and ACE inhibitors are recommended as first-line therapy; in patients with diabetes mellitus, ACE inhibitors or angiotensin receptor antagonists (or thiazides in patients with diabetes mellitus without albuminuria) are appropriate first-line therapies; and in patients with nondiabetic chronic kidney disease, ACE inhibitors are recommended. All hypertensive patients should have their fasting lipids screened, and those with dyslipidemia should be treated using the thresholds, targets and agents recommended by the Canadian Hypertension Education Program Working Group on the management of dyslipidemia and the prevention of cardiovascular disease. Selected patients with hypertension, but without dyslipidemia, should also receive statin therapy and/or acetylsalicylic acid therapy.
All recommendations were graded according to the strength of the evidence and voted on by the 43 members of the Canadian Hypertension Education Program Evidence-Based Recommendations Task Force. All recommendations reported here achieved at least 95% consensus. These guidelines will continue to be updated annually.

To provide updated, evidence-based recommendations for the diagnosis and assessment of adults with high blood pressure.
For persons in whom a high blood pressure value is recorded, a diagnosis of hypertension is dependent on the appropriate measurement of blood pressure, the level of the blood pressure elevation, the approach used to monitor blood pressure (office, ambulatory or home/self), and the duration of follow-up. In addition, the presence of cardiovascular risk factors and target organ damage should be assessed to determine the urgency, intensity and type of treatment. For persons diagnosed as having hypertension, estimating the overall risk of adverse cardiovascular outcomes requires an assessment for other vascular risk factors and hypertensive target organ damage.

Key features of the 2006 recommendations include continued emphasis on an expedited diagnosis of hypertension, an in-depth review of the role of global risk assessment in hypertension therapy, and the use of home/self blood pressure monitoring for patients with masked hypertension (subjects with hypertension who have a blood pressure that is normal in clinic but elevated on home/self measurement).
All recommendations were graded according to the strength of the evidence and were voted on by the 45 members of the Canadian Hypertension Education Program Evidence-Based Recommendations Task Force. All recommendations reported herein received at least 95% consensus. These guidelines will continue to be updated annually.
