The subject of communication between palliative care physicians and their patients regarding their diagnosis and prognosis has not been extensively researched. The purpose of this survey was to compare the attitudes and beliefs of palliative care specialists regarding communication with the terminally ill in Europe, South America, and Canada. A sample of palliative care physicians from South America (Argentina and Brazil), French-speaking Europe, and Canada were identified, and posted a questionnaire. Physicians who stated that they practised palliative care at least 30% of their time were considered evaluable as palliative care specialists. Of a total of 272 questionnaires, 228 were returned (84%); and 182/228 (81%) respondents were considered to be palliative care specialists. Palliative care physicians in all three regions believed that cancer patients should be informed of their diagnosis and the terminal nature of their illness. Physicians reported that at least 60% of their patients knew their diagnosis and the terminal stage of their illness in 52% and 24% of cases in South America, and 69% and 38% of cases in Europe, respectively. All physicians agreed that 'do not resuscitate' orders should be present, and should be discussed with the patient in all cases. While 93% of Canadian physicians stated that at least 60% of their patients wanted to know about the terminal stage of their illness, only 18% of South American, and 26% of European physicians said this (P < 0.001). Similar results were found when the physicians were asked the percentage of families who want patients to know the terminal stage of their illness. However, almost all of the physicians agreed that if they had terminal cancer they would like to know. There was a significant association between patient based decision-making and female sex (P = 0.007), older age (P = 0.04), and physicians from Canada and South America (P < 0.001). Finally, in their daily decision making, South American physicians were significantly more likely to support beneficence and justice as compared with autonomy. Canadian physicians were more likely to support autonomy as compared with beneficence. In summary, our findings suggest that there are major regional differences in the attitudes and beliefs of physicians regarding communication at the end of life. More research is badly needed on the attitudes and beliefs of patients, families, and health care professionals in different regions of the world.

Introduction The population of elderly persons is increasing andnegative outcomes due to polymedication are frequent. Discrepanciesin information about medication are frequent when older persons aretransitioning from hospital to home, increasing the risk of hospitalreadmission. The aims of this study were a) to determine discrepanciesin medical regimen indicated in two official discharge documents(DS = discharge summary, DP=discharge prescription); b) to characterizethe pharmacotherapy prescribed in older patients dischargedfrom a geriatric service.Materials & Methods Elderly patients (N=230) discharged from thegeriatric service (CHUV, Lausanne) over a 6-month period (January toJune 2009) were selected. Community pharmacists compared DS andDP to identify discrepancies including (a) drugs' name; (b) schedule ofadministration, dosage, frequency, prn prescription, treatment durationand galenic formulation. Beers' criteria were applied to identifypotentially inappropriate drugs and a descriptive analysis of drug costs,prescription profiles and generics were also performed.Results On average, patients were 82 ± 7 years old and stayed23.0 ± 11.6 days in the geriatric service. The delay between the datesof patient's discharge with the DP and the sending of the DS to hisgeneral physician averaged 14.0 ± 7.5 days (range 1-55). The DPhad an average of 10.0 ± 3.3 drugs (range 2-19). 77% of patients hadat least one discrepancy. A drug was missing on the DS in 57.8% ofpatients and 19.6% had a missing prn prescription. Among the 2312drugs prescribed, 3% belonged to Beers' list. They were prescribed to61 patients (26.5%), with 6 patients cumulating two Beers' potentiallyinappropriate drugs in their treatment. Analgesics (85% of thepatients), anticoagulants (80%), mineral supplements (77%), laxatives(52%) and antihypertensives (46%) were the drug classes most frequentlyprescribed. Mean costs of treatment as per DP was160.4 ± 179.4 Euros. Generic prescription represented more than 5%of the costs for 3 therapeutic classes (cholesterol-lowering agents(64%), antihypertensives (50%) and antidepressants (47%)).Discussion & Conclusion The high discrepancy rate between medicationlisted in the DP and the DS highlights a need for safetyimprovement. Potential benefits are expected from reinforced pharmacist-physician collaboration in transition from hospital to primarycare. In addition, even though Beers' criteria are questionable, thedrugs prescribed in this already fragile population, and the potentialopportunities of economical optimizations, are advocating thedevelopment and the scientific evaluation of a structured advancedcollaborative pharmacy practice service. This foresees improvedeffectiveness, safety and efficiency in the medication management ofelderly persons.

Owing to increasing rates of hypertension and cardiovascular-related diseases in developing countries, compliance with antihypertensive medication is major public health importance. Few studies have reported on compliance in developing countries. We determined the compliance of 187 patients with uncontrolled hypertension in the Seychelles (Indian Ocean), by assessing the presence of a biologic marker (riboflavin) in the urine. The urine tested positive in 56% of the cases. Compliance varied from one physician to another (highest 72% versus lowest 33%, P = 0.003), improved with the level of literacy (62% versus 45%, P = 0.024), and depended on the presence absence of diuretics in the medication (respectively, 45% versus 66%, P = 0.005). The ability of patients to report correctly the number of antihypertensive pills to be taken daily was a predictor of compliance (62% of the patients who gave appropriate answers had positive urine for the marker versus 31% for those giving inappropriate answers).

Background: Human immunodeficiency virus (HIV) prevalence in Switzerland is 0.4% and 30% of HIV patients are diagnosed with CD4 counts <200 cells/microliter. In 2010, the Swiss Federal Office of Public Health (SFOP) published updated guidelines regarding Physician- Initiated Counseling and Testing (PICT) for HIV. In the new guidelines, when acute HIV infection is suspected or HIV is among the differential diagnoses, an HIV test is performed without risk assessment nor prior counseling, unless the patient specifically refuses it. Counseling and verbal consent are still required when the patient asks for an HIV test or belongs to a high risk group. Whist HIV testing in the emergency departments (ED) is recommended, only 1% of patients are currently screened. Lack of awareness among physicians has been cited in the literature as the first barrier to guideline implementation. Objectives: To test if physicians working in EDs of 5 large teaching hospitals in western Switzerland, admitting 175,000 patients / year, were aware of the updated SFOP guidelines. Methods: A survey was delivered to 167 ED physicians in the summer of 2011. The survey consisted of 26 vignettes designed to test whether physicians would request an HIV test according to the new guidelines and if they knew when the PICT strategy was allowed or counseling required. Finally, physicians were asked the number of HIV tests they had requested in the previous 4 weeks, and if they were aware of the new HIV guidelines. Results are presented as mean and standard deviation, median and interquartile range (IQR), or as proportions; Student's t test was used to compare continuous variables; Results: 143 physicians returned the survey (86%); mean age was 32 ± 8 years, and median postgraduate experience of 6 years (IQR 3-12); 52% were male and 17% were attendings. The percentage of correct responses was 60 ± 13% with no difference between attendings and residents (p = 0.31); 2 of the 3 questions with the lowest scores were failure to recognize situations in which HIV testing was indicated, and the third one a failure to recognize acute HIV infection. 82% of physicians were not aware of the new guidelines. The median number of test requests was 1 (IQR 0-2, range 1-10). Conclusion: ED physicians are not aware of current HIV screening guidelines published by the SFOP, and rarely perform HIV tests. An information campaign is required if ED physicians are expected to play a significant role in the reduction of undiagnosed HIV patients.

Tämän diplomityön tavoitteena oli saada perustietoa tekijöistä, jotka vaikuttavat musteen kuivumiseen erilaisilla paperipinnoilla inkjet tulostuksessa. Tavoitteena oli saada tietoa erilaisista musteista, joita käytetään yleisimmissä inkjet tulostustekniikoissa, miten paperit vaikuttavat musteen kuivumiseen ja minkälaisia menetelmiä on olemassa musteen kuivumistekijöiden määrittämiseen. Lisäksi tarkoituksena oli varmistaa, voidaanko inkjetmusteiden absorptioajan määrittämiseen käytettävää DIGAT-laitetta käyttää määrittämään ja ennustamaan erilaisten musteiden kuivumista erilaisilla paperipinnoilla sekä etsiä korrelaatioita musteen absorptioajan ja teknisten paperiominaisuuksien sekä inkjet tulostuksen laadun välillä. Kirjallisuusosassa tarkasteltiin erilaisia inkjet tulostusmenetelmiä, niissä käytettäviä musteita ja musteiden koostumuksia. Tutkittiin myös paperin ja musteen välisiä vuorovaikutuksia sekä inkjet tulostuksen laatua. Kokeellisessa osassa tutkittiin musteenabsorboitumista paperiin DIGAT-laitteen avulla. kuudella eri musteella. Paperinäytteistä määritettiin teknisiä paperiominaisuuksia sekä ominaisuuksia, jotka liittyvät inkjet tulostuksen laatuun. Inkjet tulostuksen laatua tarkasteltiin tulostamalla testikuva kolmella eri tulostimella, jotka olivat Canon Bubble Jet i950, HP DeskJet Cxi970 ja Epson Stylus C46. Havaittiin, että DIGAT-laite ei sovellu määrittämään musteen absorptioaikoja kiiltäville näytteille.Tässä tutkimuksessa näyte, jonka kiilto oli 65 %, oli liian kiiltävä mitattavaksi DIGAT-laitteella. Lisäksi absorptiomäärityksissä havaittiin, että erilaiset musteet asettuvat erilailla paperin pintaan ja että pigmenttipohjaisella musteella asettumisaika oli kaikista pisin. Musteiden absorptioajat olivat nopeimpia erikoisinkjetpaperilla ja hitaimpia päällystetyillä, tiiviillä papereilla. Musteen absorptioajan ja teknisten paperiominaisuuksien ja inkjet tulostuksen laadun välisiä korrelaatioita oli vaikea havaita. Voidaan sanoa, että tulokset olivat muste- ja printterikohtaisia. Havaittiin vain muutamia teknisiä paperiominaisuuksia, jotka korreloivat hyvin musteen absorboitumisen kanssa. Nämäolivat Gurley-Hill huokoisuus, paperin tuhka- sekä kalsiumkarbonaattipitoisuus ja K&N värinabsorptio. Myöskään inkjet tulostuksen laadun ja musteen absorption välisiä korrelaatioita ei löytynyt kuin muutama; densiteetti, mottling sekä bleeding. Tämän tutkimuksen perusteella voidaan todeta DIGAT-laitteen soveltuvan hyvin kuvaamaan inkjet tulostuksen laatuominaisuuksista densiteettia, mottlingia sekä bleedingiä. DIGAT-laitetta voidaan siis käyttää avuksi ennustettaessa kuivumisaikaa ja sen vaikutusta edellä mainittuihin ominaisuuksiin. Läpipainatusominaisuuksia DIGAT-laitteen avulla ei voida tutkia, sillä ne ovat enemmän riippuvaisia paperin neliömassasta, paksuudesta ja huokoisuudesta kuinmusteen absorptioajasta. Teknisistä paperiominaisuuksista Gurley-Hill huokoisuus, paperin tuhka-sekä CaCO3-pitoisuus ja K&N värinabsorptio kuvaavat hyvin musteen imeytymisaikaa paperiin, kun taas ominaisuudet Cobb, HST ja polaari- sekädispersiokomponentit eivät kuvaa. Näyttää siltä, että testikuva, joka on tällä hetkellä käytössä UPM Tutkimus-keskuksessa, ei sovellu suurtehotulostuksen laadun tarkkailuun. Testikuva toimii hyvin pöytätulostimilla ja perinteisillä kopiopapereilla ja inkjetpapereilla, jotka on tarkoitettu tulostettaviksi hitaasti. Tulostusnopeuden ja musteen kuivumisnopeuden välisiä ilmiöitä seei tuo esille, joten se ei sovellu kuvaamaan suurtehotulostusta.

The antihypertensive effects of the beta-blocking agent betaxolol and the calcium entry blocker verapamil were compared in a crossover single-blind trial. Seventeen patients with uncomplicated essential hypertension took either betaxolol or a slow-release formulation of verapamil for two consecutive 6-week periods. The sequence of treatment phases was randomly allocated and a 2-week washout period preceded each treatment. The antihypertensive effect of the test drugs was assessed both at the physician's office and during everyday activities using a portable blood pressure recorder. The crossover design of the trial made it possible to evaluate the antihypertensive efficacy of betaxolol and verapamil both in the group as a whole and in the individual patient. The individual patient response to one of these agents was not a reliable indicator of the same patient's response to the alternative agent. Betaxolol brought both office and ambulatory recorded blood pressures under control in a larger fraction of patients than verapamil, although the magnitude of the blood pressure fall in the responders was equal for each drug. These observations stress the need for an individualized approach to the evaluation of antihypertensive therapy. The present results also demonstrate that optimal antihypertensive therapy is still a matter of trial and error. The precise methodology that ought to characterize crossover trials may make it possible to improve the therapeutic approach to hypertensive patients.

Although interpersonal continuity is commonly assumed to be essential for care, some patients prefer to attend a university outpatient clinic where physicians change regularly and interpersonal continuity of care is not ensured. The aim of this exploratory study was to evaluate the differences between patients attending a university outpatient clinic and patients frequenting a private practice, explore their patterns of care-seeking and their understanding of continued care. We conducted a cross-sectional study of patients attending the university medical outpatient clinic (OC) in Lausanne, Switzerland and ten randomly selected private general practices (PP). Eligible patients were >30 years, Swiss nationals or long term residents, with one or more chronic conditions and attending the same practice for >3 years. They were asked to complete a questionnaire on sociodemographic data, use of medical resources and reasons for choosing and remaining at the same practice. Semi-structured interviews were conducted with a randomly selected subset of 26 patients to further explore their preferences. 329 patient questionnaires were completed, 219 by PP and 110 by OC patients. OC patients tended to be of lower socioeconomic status than PP patients. The main reason for choosing a PP were personal recommendation, while a higher percentage of patients chose the OC because they could obtain a first appointment quickly. A higher percentage of PP patients accorded importance to physician communication skills and trust, whereas a higher percentage of OC patients favoured investigation facilities. Qualitative data suggested that although OC and PP patients reported different reasons for consulting, their expectations on the medical and relationship level were similar. Our study suggests that the two groups of patients belong to different social backgrounds, have different patterns of care-seeking and attach importance to different aspects of care continuity. However, patients' expectations and perceptions of the physician-patient relationship are similar.

BACKGROUND: Assessment of the proportion of patients with well controlled cardiovascular risk factors underestimates the proportion of patients receiving high quality of care. Evaluating whether physicians respond appropriately to poor risk factor control gives a different picture of quality of care. We assessed physician response to control cardiovascular risk factors, as well as markers of potential overtreatment in Switzerland, a country with universal healthcare coverage but without systematic quality monitoring, annual report cards on quality of care or financial incentives to improve quality. METHODS: We performed a retrospective cohort study of 1002 randomly selected patients aged 50-80 years from four university primary care settings in Switzerland. For hypertension, dyslipidemia and diabetes mellitus, we first measured proportions in control, then assessed therapy modifications among those in poor control. "Appropriate clinical action" was defined as a therapy modification or return to control without therapy modification within 12 months among patients with baseline poor control. Potential overtreatment of these conditions was defined as intensive treatment among low-risk patients with optimal target values. RESULTS: 20% of patients with hypertension, 41% with dyslipidemia and 36% with diabetes mellitus were in control at baseline. When appropriate clinical action in response to poor control was integrated into measuring quality of care, 52 to 55% had appropriate quality of care. Over 12 months, therapy of 61% of patients with baseline poor control was modified for hypertension, 33% for dyslipidemia, and 85% for diabetes mellitus. Increases in number of drug classes (28-51%) and in drug doses (10-61%) were the most common therapy modifications. Patients with target organ damage and higher baseline values were more likely to have appropriate clinical action. We found low rates of potential overtreatment with 2% for hypertension, 3% for diabetes mellitus and 3-6% for dyslipidemia. CONCLUSIONS: In primary care, evaluating whether physicians respond appropriately to poor risk factor control, in addition to assessing proportions in control, provide a broader view of the quality of care than relying solely on measures of proportions in control. Such measures could be more clinically relevant and acceptable to physicians than simply reporting levels of control.

BACKGROUND: Regional rates of hospitalization for ambulatory care sensitive conditions (ACSC) are used to compare the availability and quality of ambulatory care but the risk adjustment for population health status is often minimal. The objectives of the study was to examine the impact of more extensive risk adjustment on regional comparisons and to investigate the relationship between various area-level factors and the properly adjusted rates. METHODS: Our study is an observational study based on routine data of 2 million anonymous insured in 26 Swiss cantons followed over one or two years. A binomial negative regression was modeled with increasingly detailed information on health status (age and gender only, inpatient diagnoses, outpatient conditions inferred from dispensed drugs and frequency of physician visits). Hospitalizations for ACSC were identified from principal diagnoses detecting 19 conditions, with an updated list of ICD-10 diagnostic codes. Co-morbidities and surgical procedures were used as exclusion criteria to improve the specificity of the detection of potentially avoidable hospitalizations. The impact of the adjustment approaches was measured by changes in the standardized ratios calculated with and without other data besides age and gender. RESULTS: 25% of cases identified by inpatient main diagnoses were removed by applying exclusion criteria. Cantonal ACSC hospitalizations rates varied from to 1.4 to 8.9 per 1,000 insured, per year. Morbidity inferred from diagnoses and drugs dramatically increased the predictive performance, the greatest effect found for conditions linked to an ACSC. More visits were associated with fewer PAH although very high users were at greater risk and subjects who had not consulted at negligible risk. By maximizing health status adjustment, two thirds of the cantons changed their adjusted ratio by more than 10 percent. Cantonal variations remained substantial but unexplained by supply or demand. CONCLUSION: Additional adjustment for health status is required when using ACSC to monitor ambulatory care. Drug-inferred morbidities are a promising approach.

HIV-positive adolescents face a number of challenges in dealing with their disease and its treatment. In this qualitative study, twenty-nine HIV-positive adolescents aged 13 to 20 years (22 girls), who live in Switzerland, were asked, in a semi-structured interview (duration of 40-110 minutes), to describe their perceptions and experiences with the disease itself and with therapeutic adherence. While younger adolescents most often thought of their disease as fate, older adolescents usually knew that they had received it through vertical transmission, although the topic appeared to be particularly difficult to discuss for those living with their HIV-positive mothers. Based on their attending physician's assessment, 18 subjects were judged highly adherent, 4 fairly and 7 poorly adherent. High adherence appeared linked with adequate psychological adjustment and effective coping mechanisms, as well as with the discussion and adoption of explicit medication-taking strategies. The setting and organisation of health care teams should allow for ongoing discussions with HIV-positive adolescents that focus on their perceptions of their disease, how they cope with it and with the treatment, and how they could improve their adherence.

Physicians are in a unique position to advice smokers to quit by the ability to integrate the various aspects of nicotine dependence. This review provides an overview of intervention with smokers presenting in a primary care setting. Strategies used for smoking cessation counseling differed according to patient's readiness to quit. For smokers who do not intend to quit smoking, physicians should inform and sensitize patients about tobacco use and cessation, especially by personalizing benefits to quit and challenging smokers 'beliefs. For smokers who are dissonant, physicians should use motivational strategies, such as discussing barriers to cessation and their solutions. For smokers ready to quit, the physician should show strong support, help set a quit date, prescribe pharmaceutical therapies for nicotine dependence, such as replacement therapy and/or bupropion, with instructions for use, and suggest behavioral strategies to prevent relapse.

Social deprivation also exists in an industrialised country like Switzerland where there are many different social economic levels; social inequalities have increased in the past years having a major impact on social economic determinants of health. Being aware of these determinants and systematically identifying them in patients has become crucial for the general practitioner in order to improve the way s/he delivers care and interacts with more vulnerable populations. Because the general practitioner is often in contact with people of different socioeconomic levels, s/he is a key witness of social inequalities in health. S/he therefore has a responsibility to document them, to promote health, to prevent disease and be an advocate for the disadvantages in order to influence these social determinants of health.

To assess the reliability of the Remler system, a semi-automatic pressure recording device, several blood pressures were measured simultaneously by the conventional auscultatory method and by the Remler in 12 normotensive volunteers. In all situations tested both the Remler and auscultatory blood pressures were very close, thus demonstrating the reliability of this new technique. Ambulatory blood pressure recordings were then obtained with the Remler in 245 untreated patients referred for hypertension by their private physicians. Surprisingly, in close to 60% of them the average of all blood pressures recorded during usual activities was within the normal range. Since cardiovascular complications seem to correlate better with ambulatory than with office blood pressure levels, the Remler system appears particularly useful in recognizing those patients who, although hypertensive in the physician's office, remain normotensive during the day and therefore may not require antihypertensive treatment.

Tutkimuksen tavoitteena on selvittää ammattipienkoneiden asiakkaiden näkökulmasta taustatekijöitä ammattipienkoneiden jakelumallin perustaksi. Samalla tutkitaan jakelukanavia ja hankintaan liittyviä asiakastyytyväisyystekijöitä sekä jälkimarkkinoinnin merkitystä. Tutkimuksen empiirisessä osassa selvitetään ammattipienkoneiden käyttö, käytetyt merkit ja hankintapaikat. Lisäksi selvitetään hankintaan ja markkinointiin/jälkimarkkinointiin liittyviä asiakastyytyväisyystekijöitä. Lopuksi tutkitaan ammattipienkoneiden käyttäjien tulevaisuuden arvostuksia koskien hankintapaikkaa, markkinointia ja ostokriteerejä. Tutkimusmenetelmänä käytettiin kvantitatiivista tutkimusotetta. Tutkimus suoritettiin joulukuussa 2006 postikyselynä. Perusjoukkona olivat Suomen ammattipienkonekäyttäjät, jotka koostuivat kaupunkien ja kuntien palveluksessa olevista, kiinteistönhuoltoyhtiöiden palveluksessa olevista ja alan yksityisyrittäjistä. Otos oli systemaattinen eli tasaväliotanta. Perusjoukko oli 1650 ihmistä ja otos 465 ihmistä. Vastausprosentiksi tuli 27,1 %. Tutkimuksen tulokseksi saatiin, että ammattipienkoneasiakkaat hankkivat jo tänä päivänä ja haluavat hankkia tulevaisuudessakin tuotteet lähinnä erikoispienkoneliikkeistä. Jälleenmyyjän varaosapalvelukyky, ammattitaito ja palveluhalukkuus sekä liikkeen yhteydessä oleva huolto ovat tärkeimpiä asiakastyytyväisyyteen johtavia tekijöitä. Johtopäätöksenä tästä voidaan todeta, että ammattipienkonemaahantuojien kannattaa tulevaisuudessakin panostaa erikoisliikkeisiin tuotteiden jakelussa. Markkinoinnissa kannattaa mainonnan sijasta kouluttaa ja opastaa jälleenmyyjää, koska hän on tärkein tiedon hankinnan lähde tulevaisuudessa ammattipienkoneasiakkaille.

Current treatment guidelines consider diabetes to be equivalent to existing cardiovascular disease (CVD), but few data exist about the relative importance of these risk factors for total and CVD mortality in older women.We studied 9704 women aged >= 65 years enrolled in a prospective cohort study (Study of Osteoporotic Fracture) during a mean follow-up of 13 years and compared all-cause and CVD mortality among non-diabetic women without and with history of CVD at baseline and diabetic women without and with history of CVD. Diabetes mellitus and CVD were defined as self-report of physician diagnoses. Cause of death was adjudicated from death certificates and medical records when available. Ascertainment of vital status was 99% complete. Multivariate Cox hazard models adjusted for age, smoking, physical activity, systolic blood pressure, waist girth and education were used to compare mortality among the four groups with non-diabetic women without CVD as the referent group. At baseline mean age was 71.7 } 5.3 years, 7.0% reported diabetes mellitus and 14.5% reported prior CVD. 4257 women died during follow-up, 36.6% were attributed to CVD. Compared to non-diabetic women without prior CVD, the risk of CVD mortality was elevated among both non-diabetic women with CVD (HR = 1.82, 95% CI: 1.60-2.07, P <0.001) and diabetic women without prior CVD (HR = 2.24, CI: 1.87-2.69, P <0.001). CVD mortality was highest among diabetic women with CVD (HR = 3.41, CI: 2.61-4.45, P <0.001). Compared to non-diabetic women with CVD, diabetic women without prior CVD had a significantly higher adjusted HR for total and CVD mortality (P < 0.001 and P <0.05 respectively). Older diabetic women without prior CVD have a higher risk of all-cause and CVD mortality compared to nondiabetic women with pre-existing CVD. For older women, these data support the equivalence of prior CVD and diabetes mellitus in current guidelines for the prevention of CVD in primary care.
