Evaluation qualitative de la compliance médicale [Qualitative evaluation of medical compliance].

OBJECTIVE: The effectiveness of CLP (Consultation and liaison psychiatry) interventions in a general hospital is difficult to evaluate; parameters potentially determinant as to effectiveness are numerous. Effectiveness evaluations are almost exclusively restricted to the duration of hospitalization. Since CLP may and often should be manifest beyond discharge, we intended to determine the agreement between our proposition and its execution as a measure of effectiveness. METHOD: We based our analyses principally on the general practitioner's appreciation of the CLP impact, a measure of effectiveness at distance from the consultation by a judge not directly involved in the consulting process. This qualitative assessment is based on a population of 50 patients. RESULTS: Our results suggest that agreement between our proposal and its complete execution is good concerning medication (90%) and referral rate after the hospitalization (85%), average as to liaison suggestions (65%) and clearly weak as to propositions regarding further investigations (< 30%). CONCLUSION: CLP proposals must be as close as possible to the in-patient physician's preoccupations to enhance the probability that they be executed. The concordance as to the proposal and its execution as well as the CLP impact estimation need be evaluated at distance. This evaluation must imply the general practitioner's assessment.

Low compliance with dietary recommendations for food intake among adults.

BACKGROUND & AIMS: To assess the adherence to the national dietary recommendations and to identify factors contributing to dietary compliance in Switzerland. METHODS: Population-based cross-sectional study in Lausanne, Switzerland (CoLaus study), 2009-2012. Dietary intake was assessed using a validated food frequency questionnaire. Participants were dichotomized according to whether they followed the national recommendations for fruits, vegetables, meat, fish and dairy products. RESULTS: Data from 4371 participants (54% women, mean age ± SD: 57.6 ± 10.5 years) were analyzed. Compliance with the recommendations was low: only 39.4%, 7.1%, 61.3%, 66.4%, and 8.4% complied with the Swiss recommendations for fruit (≥2/day), vegetables (≥3/day), meat (≤5/week), fish (≥1/week) and dairy products (≥3/day), respectively. In multivariate analyses, gender, age, smoking status, Swiss-born status, education, being on a diet and body mass index were associated with dietary compliance, while no difference was found between women before and after menopause. Factors specifically associated with fruits, vegetables, meat, fish or dairy products recommendations were identified. CONCLUSION: The low degree of compliance with dietary recommendations calls for a continued effort to increase the population awareness of the importance of a healthy and balanced diet, especially for vegetables and dairy products. This study identified determinants that should guide this effort.

Why Objective Monitoring of Compliance is Important in the Management of Hypertension.

Hypertensive patients often experience poor adherence to treatment, a frequent cause of uncontrolled blood pressure. In this study, we have evaluated whether or not the use of electronic monitoring for drug adherence is a useful approach to identify and correct compliance problems in hypertensive patients, which may ultimately enhance the effect of antihypertensive therapy. Sixty-nine treated patients with an office blood pressure greater than 140/90 mm Hg were enrolled in this study. With patient consent, current antihypertensive therapy was dispensed in electronic pillboxes that record the time and date of each opening without changing the drug regimen. The intention was to provide physicians with objective measurements of drug compliance. The monitoring of compliance per se without any other intervention induced a marked decrease of blood pressure in the whole group (from 159/104Â+/-23/12 mm Hg to 143/92Â+/-20/15, meansÂ+/-standard deviation, p less than 0.001). A complete normalization of blood pressure (less than 140/90 mm Hg) was obtained in one third of the patients (group 1, n=23) during the monitoring period. A significant improvement of blood pressure control was found in another third (group 2, n=23), whereas in the remaining patients (group 3, n=23) no change in blood pressure was observed. The distribution of individual compliance values, as well as the mean compliances was comparable in the three subgroups. Conversely, the compliance reports have identified several potentially overtreated patients in group 1, a large number of patients with a poor adherence to the prescribed therapy in all groups, and patients who clearly needed a change in pharmacotherapy mainly in group 3. Thus, our results suggest that electronic monitoring of compliance can considerably enhance the efficacy of antihypertensive therapy in patients with uncontrolled hypertension. This procedure should be used more extensively in clinical practice whenever the blood pressure response to therapy appears insufficient. (c)2000 by Le Jacq Communications, Inc.

Evaluation of arterial compliance-pressure curves. Effect of antihypertensive drugs.

A new high-precision ultrasonic device was developed to determine noninvasively arterial compliance as a function of blood pressure. Because of the nonlinear elastic properties of arterial walls, measurements of compliance can be appropriately compared only if obtained over a range of pressures. This apparatus was used to evaluate in a double-blind, parallel fashion the effect of three different antihypertensive drugs and of a placebo on radial artery compliance. Thirty-two normotensive volunteers were randomly allocated to an 8-day, once-a-day oral treatment with either a placebo, 100 mg atenolol, 20 mg nitrendipine, or 20 mg lisinopril. Blood pressure, heart rate, radial artery diameter, and arterial compliance were measured immediately before as well as 6 hours after dosing on the first and last days of the study. On the eighth day of administration, within 6 hours after dosing, lisinopril induced an acute increase in radial artery diameter, from 2.99 +/- 0.06 to 3.28 +/- 0.09 mm (mean +/- SEM, p less than 0.01). The compliance-pressure curve was shifted upward on day 1 (p less than 0.01) as well as on day 8 (p less than 0.05). None of the other drugs induced any significant modification of these parameters. Arterial compliance has a strong nonlinear dependency on intra-arterial pressure and therefore has to be defined as a function of pressure. Antihypertensive drugs acting by different mechanisms may have different effects on the mechanical properties of large arteries.

A Confluence of Risks: Control and Compliance in the World of Unstructured Data, Big Data and the Cloud

The emergence of powerful new technologies, the existence of large quantities of data, and increasing demands for the extraction of added value from these technologies and data have created a number of significant challenges for those charged with both corporate and information technology management. The possibilities are great, the expectations high, and the risks significant. Organisations seeking to employ cloud technologies and exploit the value of the data to which they have access, be this in the form of "Big Data" available from different external sources or data held within the organisation, in structured or unstructured formats, need to understand the risks involved in such activities. Data owners have responsibilities towards the subjects of the data and must also, frequently, demonstrate that they are in compliance with current standards, laws and regulations. This thesis sets out to explore the nature of the technologies that organisations might utilise, identify the most pertinent constraints and risks, and propose a framework for the management of data from discovery to external hosting that will allow the most significant risks to be managed through the definition, implementation, and performance of appropriate internal control activities.

Influence of compliance to respiratory weaning consensus conference criteria on respiratory outcome within 48h after planned extubation

INTRODUCTION. A two-step assessment (readiness to wean (RW) followed by spontaneousbreathing trial (SBT)) of predefined criteria is recommended before planned extubation(PE)1.OBJECTIVES. We aimed to evaluate if compliance to all guideline criteria was associatedwith better respiratory outcome within 48 h after PE.METHODS. The data (extracted from our clinical information system) of 458 consecutivepatients who underwent PE after C48 h of invasive ventilation in our medico-surgical ICUwere analyzed. We evaluated compliance with guidelines [1] regarding respiratory rate, tidalvolume, PaO2, FiO2, PEEP, PaCO2, pH, heart rate, systolic arterial pressure and arrhythmiaduringRWand SBT assessment (RW and SBT within 2 h). A patient was classified as RW+ ifallRWcriteria were fulfilled andRW-if at least 1 criterion was violated. The same approachwas used to define SBT+ and SBT- patients. During the 48 h following PE, we assessed theoccurrence of post-PE respiratory failure (PRF) (defined as the presence of at least 1 consensuscriterion of respiratory failure [1]), reintubation (after NIV failure or because of immediateintubation criteria) and cumulative duration of post-PE ventilation (PPEV = Post-PE invasive+ non-invasive ventilation). ICU mortality was recorded. Comparisons for variousoutcomes were performed by Chi-square and t tests.RESULTS. All consensus criteria were fulfilled in 77.3% of the patients during RW and in68.1% of the patients during SBT.[Compliance to weaning criteria and outcome]N = 458 PRF (%) Reintubation (%) PPEV (min) ICU mortality (%)All patients 53.5 10.0 542 ± 664 6.1RW+ 50.0 9.3 490 ± 626 5.4RW- 65.4* 12.5 718 ± 757** 8.7SBT+ 52.6 8.0 498 ± 594 6.7SBT- 55.5 14.4*** 637 ± 788**** 4.8Occurrence of PRF only was not associated with increased ICU mortality: 4.2 versus 7.8%,p = 0.11.

As mortality was increased by reintubation,more sensitive and specific criteria to predict the risk of reintubation are probably needed.REFERENCE. Boles JM, et al. Eur Respir J 2007;29:1033-56.

Compliance to dietary advice directed towards increasing the carbohydrate to fat ratio of the everyday diet.

OBJECTIVE: To assess the effects, on food intake, body weight and body composition, of compliance to advice aiming at increasing the carbohydrate to fat ratio of the everyday diet without imposing voluntary restriction on the amount of food consumed. DESIGN: Eight moderately overweight women (body mass index > 27 kg/m2, relative body fat mass > 30%) received dietary advice during a 2 month period. Additionally, each evening the subjects had to consume a meal artificially enriched with 13C-glucose in order to assess their compliance from the 13CO2 enrichment in expired air. MEASUREMENTS: Dietary intakes, body weight, body composition and individual compliance. RESULTS: The energy derived from fat decreased from 44 +/- 1% to 31 +/- 1% and the proportion of carbohydrate increased from 38 +/- 2% to 50 +/- 1%, whereas the absolute carbohydrate intake remained constant (182 +/- 18 g/d). Energy intake decreased by 1569 +/- 520 kJ/d. There was a net loss of fat mass (1.7 +/- 0.7 kg, P = 0.016) with fat free mass maintenance. Dietary compliance ranged from 20 to 93% (mean: 60 +/- 8%) and was positively correlated to the loss of body fat mass. CONCLUSION: Advice aiming at increasing diet's carbohydrate to fat ratio induces a loss of fat mass with fat-free mass maintenance.

Patients' information-seeking activity is associated with treatment compliance in inflammatory bowel disease patients.

Background. Despite the chronic and relapsing nature of inflammatory bowel diseases (IBD), at least 30% to 45% of the patients are noncompliant to treatment. IBD patients often seek information about their disease. Aim. To examine the association between information-seeking activity and treatment compliance among IBD patients. To compare information sources and concerns between compliant and noncompliant patients. Methods. We used data from the Swiss IBD cohort study, and from a qualitative survey conducted to assess information sources and concerns. Crude and adjusted odds ratios (OR) for noncompliance were calculated. Differences in the proportions of information sources and concerns were compared between compliant and noncompliant patients. Results. A total of 512 patients were included. About 18% (n = 99) of patients were reported to be noncompliant to drug treatment and two-thirds (n = 353) were information seekers. The OR for noncompliance among information seekers was 2.44 (95%CI: 1.34-4.41) after adjustment for confounders and major risk factors. General practitioners were 15.2% more often consulted (p = 0.019) among compliant patients, as were books and television (+13.1%; p = 0.048), whereas no difference in proportions was observed for sources such as internet or gastroenterologists. Information on tips for disease management were 14.2% more often sought among noncompliant patients (p = 0.028). No difference was observed for concerns on research and development on IBD or therapies. Conclusion. In Switzerland, IBD patients noncompliant to treatment were more often seeking disease-related information than compliant patients. Daily management of symptoms and disease seemed to be an important concern of those patients.

Monitoring one-year compliance to antihypertension medication in the Seychelles.

OBJECTIVE: To examine the compliance to medication among newly diagnosed hypertensive patients screened from the general population of the Seychelles, a rapidly developing country. METHODS: Among the 1067 participants to a population-based survey for cardiovascular risk factors, hypertension was discovered in 50 (previously unaware of having hypertension and having blood pressure > or = 160/95 mmHg over 3 visits). These 50 patients were placed on a daily one-pill regimen of medication (bendrofluazide, atenolol, or a combination of hydrochlorothiazide and atenolol) and compliance to the regimen was assessed over 12 months using electronic pill containers. Satisfactory compliance was defined as taking the medication on 6 or 7 days a week on average (which corresponds to a mean compliance level of > or = 86%). FINDINGS: In the first month, fewer than half (46%) of the new hypertension patients achieved satisfactory compliance, and only about one-quarter (26%) achieved this level by the twelfth month. Compliance was better among the 23 participants who regularly attended medical follow-up, with nearly three-quarters of these patients (74%) achieving satisfactory compliance during the first month and over one-half (55%) by the twelfth month. There was a direct association between mean 12-month compliance level and having a highly skilled occupation; having good health awareness; and regularly attending medical appointments. In contrast, there was an inverse relationship between mean compliance level and heavy drinking. CONCLUSION: The low proportion of people selected from the general population who were capable of sustaining satisfactory compliance to antihypertension medication may correspond to the maximum effectiveness of medication interventions based on a screening and treatment strategy in the general population. The results stress the need for both high-risk and population approaches to improve hypertension control.

Conduit artery compliance and distensibility are not necessarily reduced in hypertension.

The goal of this study was to investigate whether the elastic behavior of conduit arteries of humans or rats is altered as a result of concomitant hypertension. Forearm arterial cross-sectional compliance-pressure curves were determined noninvasively by means of a high precision ultrasonic echo-tracking device coupled to a photoplethysmograph (Finapres system) allowing simultaneous arterial diameter and finger blood pressure monitoring. Seventeen newly diagnosed hypertensive patients with a humeral blood pressure of 163/103 +/- 4.4/2.2 mm Hg (mean +/- SEM) and 17 age- and sex-matched normotensive controls with a humeral blood pressure of 121/77 +/- 3.2/1.9 mm Hg were included in the study. Compliance-pressure curves were also established at the carotid artery of 16-week-old anesthetized spontaneously hypertensive rats (n = 14) as well as Wistar-Kyoto normotensive animals (n = 15) using the same echo-tracking device. In these animals, intra-arterial pressure was monitored in the contralateral carotid artery. Mean blood pressures averaged 197 +/- 4 and 140 +/- 3 mm Hg in the hypertensive and normotensive rats, respectively. Despite the considerable differences in blood pressure, the diameter-pressure and cross-sectional compliance-pressure and distensibility-pressure curves were not different when hypertensive patients or animals were compared with their respective controls. These results suggest that the elastic behavior of a medium size muscular artery (radial) in humans and of an elastic artery (carotid) in rats is not necessarily altered by an increase in blood pressure.

Compliance with the Swiss Society for Nutrition's dietary recommendations in the population of Geneva, Switzerland: a 10-year trend study (1999-2009).

The trends in compliance with the dietary recommendations of the Swiss Society for Nutrition in the Geneva population were assessed for the period from 1999 to 2009 using 10 cross-sectional, population-based surveys (Bus Santé study) with a total of 9,320 participants aged 35 to 75 years (50% women). Dietary intake was assessed using a self-administered, validated, semi-quantitative food frequency questionnaire. Trends were assessed by logistic regression adjusting for age, smoking status, education, and nationality using survey year as the independent variable. After excluding participants with extreme intakes, the percentage of participants with a cholesterol intake of <300 mg/day increased from 40.8% in 1999 to 43.6% in 2009 for men (multivariate-adjusted P for trend=0.04) and from 57.8% to 61.4% in women (multivariate-adjusted P for trend=0.06). Calcium intake >1 g/day decreased from 53.3% to 46% in men and from 47.6% to 40.7% in women (multivariate-adjusted P for trend<0.001). Adequate iron intake decreased from 68.3% to 65.3% in men and from 13.3% to 8.4% in women (multivariate-adjusted P for trend<0.001). Conversely, no significant changes were observed for carbohydrates, protein, total fat (including saturated, monounsaturated, and polyunsaturated fatty acids), fiber, and vitamins D and A. We conclude that the quality of the Swiss diet did not improve between 1999 and 2009 and that intakes deviate substantially from expert recommendations for health promotion and chronic disease risk reduction.
