Проблемний характер інформаційно-знаннєво-прогнозних атракторів у системі науки

У роботі зосереджується увага на дослідженні самоорганізаційних процесів у науковій системі, базуючись на таких модельних атракторах, як інформація, знання і передбачення. Проведений аналіз стосується теорії розвитку наукового знання і практичного наукознавства. Показано, що для розвитку наукової системи єдино можливим є інноваційний шлях — створення віртуальних структур з раціональною та ефективною системою діяльності (на прикладі Державного фонду фундаментальних досліджень). Розглядаються інформаційні ресурси як характеристика рівня упорядкованості, складності систем знань та критерії їх оцінки. Аналізуються особливості побудови систем достовірного знання, забезпечення відкритого доступу до інформації/знань з метою стимуляції наукової ініціативи та творчості. Акцент зроблено на технічному прогнозуванні: дослідженні тенденцій, виявленні нових проблем і можливих шляхів їх розв’язання. Наведено приклади можливостей науки, її перспектив, що переконливо свідчать про потребу змін сучасної науково-технічної політики (як у формуванні, так і в реалізації) шляхом визначення пріоритетів розвитку. Деталізовано проблему реалізації об’єктивної системи оцінювання результатів фундаментальних наукових досліджень.В работе сосредоточено внимание на исследовании самоорганизационных процессов в научной системе, базируясь на таких модельных атракторах, как информация, знание и предвидение.

Приводятся примеры возможностей науки, ее перспектив, что убедительно свидетельствует о необходимости изменений научно-технической политики (как в формировании, так и в реализации) путем определения приоритетов развития. Детализирована проблема реализации объективной системы оценивания результатов фундаментальных научных исследований.Self-organizing processes within the science system are studied on the basis of model attractors such as information, knowledge and prediction. The analysis deals with the theory of scientific knowledge development and practical science of science (science studies). By example of the State Fund for Basic Research it’s shown that the development of scientific knowledge is only possible by way of innovation, that is, creation of virtual entities with rational and effective system of action. Information resources are treated as a characteristic of the level of systematization and complexity of the knowledge systems, and as their evaluation criteria. Specifics of building up authentic knowledge systems and ensuring the opened access to information\knowledge as a driver for scientific initiative and creativity are analyzed. Emphasis is made on technical prediction: studies of tendencies, identification of new problems and ways for their solutions. Examples of science capabilities and prospects are given, which convincingly proves the need for change in the current S&T policy (its formulation and implementation) through defining the development priorities. The problem related with applications of a sound system for evaluating results of basic research is shown in detail

No difference in between-country variability in use of newly approved orphan and non- orphan medicinal products - a pilot study

<p>Abstract</p> <p>Background</p> <p>Regulators and payers have to strike a balance between the needs of the patient and the optimal allocation of resources. Drugs indicated for rare diseases (orphan medicines) are a special group in this context because of their often high per unit costs. Our objective in this pilot study was to determine, for drugs used in an outpatient setting, how utilisation of centrally authorised drugs varies between countries across a selection of EU member states.</p> <p>Methods</p> <p>We randomly selected five orphan medicines and nine other drugs that were centrally authorised in the European Union between January 2000 and November 2006. We compared utilisation of these drugs in six European Union member states: Austria, Denmark, Finland, Portugal, The Netherlands, and Sweden. Utilisation data were expressed as Defined Daily Doses per 1000 persons per year. Variability in use across countries was determined by calculating the relative standard deviation for the utilisation rates of individual drugs across countries.</p> <p>Results</p> <p>No association between orphan medicine status and variability in use across countries was found (P = 0.52). Drugs with an orphan medicine status were more expensive and had a higher innovation score than drugs without an orphan medicine status.</p> <p>Conclusions</p> <p>The results show that the variability in use of orphan medicines in the different health care systems of the European Union appears to be comparable to the other newly authorised drugs that were included in the analysis. This means that, although strong heterogeneity in access may exist, this heterogeneity is not specific for drugs with an orphan status.</p

The association between prescription change frequency, chronic disease score and hospital admissions: a case control study

BACKGROUND: The aim of this study was to assess the association between prescription changes frequency (PCF) and hospital admissions and to compare the PCF to the Chronic Disease Score (CDS). The CDS measures comorbidity on the basis of the 1-year pharmacy dispensing data. In contrast, the PCF is based on prescription changes over a 3-month period. METHODS: A retrospective matched case–control design was conducted. 10.000 patients were selected randomly from the Dutch PHARMO database, who had been hospitalized (index date) between July 1, 1998 and June 30, 2000. The primary study outcome was the number of prescription changes during several three-month time periods starting 18, 12, 9, 6, and 3 months before the index date. For each hospitalized patient, one nonhospitalized patient was matched for age, sex, and geographic area, and was assigned the same index date as the corresponding hospitalized patient. We classified four mutually exclusive types of prescription changes: change in dosage, switch, stop and start. RESULTS: The study population comprised 8,681 hospitalized patients and an equal number of matched nonhospitalized patients. The odds ratio of hospital admission increased with an increase in PCF category. At 3 months before the index date from PCF=1 OR 1.4 [95% CI 1.3-1.5] to PCF= 2–3 OR 2.2 [95% CI 1.9-2.4] and to PCF ≥ 4 OR 4.1 [95% CI 3.1-5.1]. A higher CDS score was also associated with an increased odds ratio of hospitalization: OR 1.3 (95% CI 1.2-1.4) for CDS 3–4, and OR 3.0 (95% CI 2.7-3.3) for CDS 5 or higher. CONCLUSION: The prescription change frequency (PCF) is associated with hospital admission, like the CDS. Pharmacists and other healthcare workers should be alert when the frequency of prescription changes increases. Clinical rules could be helpful to make pharmacists and physicians aware of the risk of the number of prescription changes

Linking community pharmacy dispensing data to prescribing data of general practitioners

BACKGROUND: Databases are frequently used for pharmacoepidemiological research. However, most of these databases consist either of prescribing, dispensing or administrative data and therefore lack insight in the interaction between the several health professionals around the patient. METHODS: To determine the success rate of linking records from the dispensing database of the Foundation for Pharmaceutical Statistics to the prescribing database of the second Dutch national survey of general practice, conducted by NIVEL (Netherlands Institute for Health Services Research), a deterministic record linkage approach was used with patient and prescription characteristics as matching variables between the two databases. RESULTS: The catchment area included 123 community pharmacies, 90 GP practices and approximately 170,000 unique patients. Overall 110,102 (64.8%) unique patients were linked using the matching variables patient's gender, year of birth, the 4-digit part of the postal code, date of dispensing/prescribing and ATC-code. The final database contains of the 110,102 both prescribing data from 83 GP practices and dispensing data of 112 community pharmacies. CONCLUSION: This study shows that linkage of dispensing to prescribing data is feasible with a combination of patient characteristics, such as gender, year of birth and postal code, and prescription characteristics like prescription date and ATC-code. We obtained a linkage proportion of 64.8% resulting in complete prescribing and dispensing history of 110,102 patients. This offers an opportunity to gain insight in the mechanisms and factors influencing drug utilisation in general practice

BACKGROUND: Psychotropic drugs are prescribed to approximately 30-40% of adults with intellectual disability (ID) and challenging behaviour, despite the limited evidence of effectiveness and the potential of adverse events. AIMS: To assess the prevalence of adverse events in association with psychotropic drug use in adults with ID and challenging behaviour and to examine the relation of these adverse events with the person's quality of life. METHOD: The presence of adverse events was measured with a questionnaire that had to be filled in by the physicians of the participants. Movement disorders were measured separately with a standardised protocol. The strength of the association between adverse events and Intellectual Disability Quality of Life-16 (IDQOL-16), and daily functioning was investigated using linear regression analyses, taking into account the severity of disease (CGI-S) as potential confounder. RESULTS: Virtually all of 103 adults with ID and challenging behaviour had at least one adverse event (84.4%) and almost half had ≥3 adverse events (45.6%) across different subclasses. Using psychotropic drugs increased the prevalence of adverse events significantly. Respectively 13% of the patients without psychotropic drugs and 61% of the patients with ≥2 psychotropic drugs had ≥3 adverse events. Having adverse events had a significantly negative influence on the quality of life. CONCLUSIONS: A large majority of all patients had at least one adverse event associated with psychotropic drug use. More attention is needed for these adverse events and their negative influence on the quality of life of these patients, taking into account the lack of evidence of effectiveness of psychotropic drugs for challenging behaviour

Less discontinuation of ADHD drug use since the availability of long-acting ADHD medication in children, adolescents and adults under the age of 45 years in the Netherlands

Treatment options for ADHD in the Netherlands have increased with the introduction of the extended-release formulations of methylphenidate (MPH ER, Concerta®) in 2003 and atomoxetine (ATX, Strattera®) in 2005, but data on the effect on drug usage patterns are scarce. The objective of the present study was to describe changes in the patterns of ADHD medication use and determinants thereof among children, adolescents and adults (<45 years) starting ADHD medication since the introduction of MPH ER and ATX. Data were obtained from Dutch community pharmacies as collected by the Foundation for Pharmaceutical Statistics, covering 97% of all dispenses for prescription medicines to outpatients in the Netherlands. Usage patterns (continuation, discontinuation, switching and addition) of ADHD drugs were evaluated at 3, 6 and 12 months after initiation for three separate time cohorts (patients starting ADHD medication in Jan-Dec 2002, Jan 2003–June 2004, respectively July 2004–Dec 2005). It was found that between 2002 and 2006, most ADHD drug users were initiated on methylphenidate IR. Discontinuation of any ADHD drug treatment decreased over time partly in favour of switching and addition. Discontinuation at 3 months decreased from around 33% to around 25%, at 6 months from less than 50% to almost 35%, and at 12 months from just fewer than 60% to less than 45%. Discontinuation was higher among females and in adults >18 years. After the introduction of MPH ER and ATX (time cohort III), 16.5% of the incident ADHD drug users switched their medication and almost 9% added an ADHD drug to the prior ADHD drug. In conclusion, discontinuation of incident ADHD drug use is high after 3, 6 and 12 months. During the study period, the incidence of discontinuation decreased because of the availability of extended-release methylphenidate and atomoxetine

Association between HTR2C polymorphisms and weight loss in obese patients

OBJECTIVE To investigate whether the HTR2C rsUU334 and 759 C/T polymorphisms are associated with weight loss in an anti- obesity programme. DESIGN AND METHODS A longitudinal observational follow-up study was used to assess the association between HTR2C genotypes and weight loss during a nine month programme in an obesity clinic. Caucasian patients aged 18 years or older were included. Data were extracted from the patients' medical records. In total, 128 patients were included 129 males). RESULTS There was a significant association between the HTR2C 759 T allele and resistance to weight loss in the first month of the programme. For each T allele present, there was 0.78% (95% confidence interval [95%-CI] 0.19-1.38; P = 0.011 less weight loss (as a percentage of the body weight at start). Patients carrying the variant HTR2C 759 T allele were also less likely to reach > 7% weight loss (odds ratio [OR] 0.23; 95%-CI 0.06- 0,85; P = 0.028), and dropped out of the programme sooner [-0.78 months; 95%-CI -1.51- -0.06; P = 0.035; corrected for gender). No associations with the HTR2C rsUU334- genotype and any of the primary endpoints for weight loss or secondary endpoints were found. CONCLUSION Patients carrying the HTR2C 759 T allele were more resistant to weight loss and dropped out of the programme sooner. However, these effects were small and only explained a small part of a very complex puzzle. Genotyping HTR2C to predict a patient's chance of success in an obesity clinic is therefore not warranted
