Recommendations on TNFα inhibitor biosimilar use in clinical practice: a comparison of European gastroenterology IBD guidance
Background: Professional associations publish guidance advising gastroenterologists on prescribing biosimilars; however, guidelines differ between countries and change over time. This study aimed to map the presence and content of guidance from European gastroenterology associations on TNFα inhibitor biosimilar use and its development over time. Research design and methods: Guidelines on biosimilar prescribing from national gastroenterology associations in the European Economic Area (EEA) partnered with the European Crohn’s and Colitis Organization (ECCO) were collected. Treatment guidelines and biosimilar position papers from 2010 to 2022 were included. Data were extracted using a template. Results: 26 of 30 EEA countries have an ECCO-partnered gastroenterology association, of which 14 (53.8%) had national guidelines addressing biosimilars, four (15.4%) followed ECCO’s position, and three (11.6%) had treatment guidelines without mentioning biosimilars. From five countries (19.2%) no guidelines were retrieved. Among 18 countries with guidance, 14 (77.8%) associations endorsed initiating biological treatment with biosimilars, and 13 (72.2%) endorsed transitioning from originator to biosimilar. Nine associations published multiple guidelines over time addressing biosimilars; overall, their positions became more encouraging. Conclusions: The majority of gastroenterology associations endorsed biosimilar use. The lack of (up-to-date) guidelines for some associations indicates an area of improvement to support biosimilar use in clinical practice
Evaluation of patients’ experiences with antidepressants reported by means of a medicine reporting system
Factors associated with psychotropic drug use among community-dwelling older persons: A review of empirical studies
BACKGROUND: In the many descriptive studies on prescribed psychotropic drug use by community-dwelling older persons, several sociodemographic and other factors associated with drug use receive inconsistent support. METHOD: Empirical reports with data on at least benzodiazepine or antidepressant drug use in samples of older persons published between 1990 and 2001 (n = 32) were identified from major databases and analyzed to determine which factors are most frequently associated with psychotropic drug use in multivariate analyses. Methodological aspects were also examined. RESULTS: Most reports used probability samples of users and non-users and employed cross-sectional designs. Among variables considered in 5 or more reports, race, proximity to health centers, medical consultations, sleep complaints, and health perception were virtually always associated to drug use. Gender, mental health, and physical health status were associated in about two-thirds of reports. Associations with age, marital status, medication coverage, socioeconomic status, and social support were usually not observed. CONCLUSIONS: The large variety of methods to operationalize drug use, mental health status, and social support probably affected the magnitude of observed relationships. Employing longitudinal designs and distinguishing short-term from long-term use, focusing on samples of drug users exclusively, defining drug use and drug classes more uniformly, and utilizing measures of psychological well-being rather than only of distress, might clarify the nature of observed associations and the direction of causality. Few studies tested specific hypotheses. Most studies focused on individual characteristics of respondents, neglecting the potential contribution of health care professionals to the phenomenon of psychotropic drug use among seniors
The Relationship Between Study Characteristics and the Prevalence of Medication-Related Hospitalizations A Literature Review and Novel Analysis
Incidence of antidepressant drug use in older adults and association with chronic diseases: The Rotterdam Study
Frequency of and risk factors for preventable medication-related hospital admissions in the Netherlands
Background: Medication-related problems that lead to hospitalization have been the subject of many studies, many of which were limited to 1 hospital or lacked patient follow-up. Furthermore, little information exists on potential risk factors associated with preventable medication-related hospitalizations. Methods: A prospective multicenter study was conducted to determine the frequency and patient outcomes of medication-related hospital admissions. A case-control design was used to determine risk factors for potentially preventable admissions. All unplanned admissions in 21 hospitals were assessed during 40 days. Controls were patients admitted for elective surgery. Cases and controls were followed up until hospital discharge. The frequency of medication-related hospital admissions, potential preventability, and outcomes were assessed. For potentially preventable medication-related admissions, risk factors were identified in the case-control study. Results: Almost 13 000 unplanned admissions were screened, of which 714 (5.6%) were medication related. Almost half (46.5%) of these admissions were potentially preventable, resulting in 332 case patients matched with 332 controls. Outcomes were favorable in most patients. The main determinants of preventable medication-related hospital admissions were impaired cognition (odds ratio, 11.9; 95% confidence interval, 3.9-36.3), 4 or more comorbidities (8.1; 3.1-21.7), dependent living situation (3.0; 1.4-6.5), impaired renal function (2.6; 1.6-4.2), nonadherence to medication regimen (2.3; 1.4-3.8), and polypharmacy (2.7; 1.6-4.4). Conclusions: Adverse drug events are an important cause of hospitalizations, and almost half are potentially preventable. The identified risk factors provide a starting point for preventing medication-related hospital admissions
Long-term use of antidepressants in the Netherlands in 1991-2001:prevalence, incidence and risk indicators
Long-term use of antidepressants in the Netherlands in 1991-2001:prevalence, incidence and risk indicators
Objective. To determine the prevalence, incidence and average duration of use of selective serotonin-reuptake inhibitors (SSRIs) and tricyclic antidepressants (TCAs) in the Netherlands in 1992-2001, as well as the incidence of prolonged SSRI use and the possible determinants thereof in the years 1991-1997.Design. Descriptive.Method. On the basis of pharmacy data in the PHARMO-database on approximately 850,000 patients, a calculation of the prevalence (number of users of an antidepressant per 1000 persons on an arbitrary day) and the incidence (number of new users per 1000 persons per year) was made for each year. Prolonged use was defined as the uninterrupted use of an antidepressant during at least 12 months. The relative risk for prolonged use was calculated and corrected for possible determinants with the aid of Poisson and Cox regression analysis.Results. Both the prevalence (2.2 to 17.1 per 1000 persons) and the incidence (3-7 to 14.5 per 1000 persons per year) of the use of SSRIs increased in the period 1992-2001 while the use of TCAs remained stable. An increasing number of the 9857 SSRI-users who were included in the follow-up study became long-term users (n = 2909) during the treatment (a total of 30%). Female gender, advanced age, prior use of benzodiazepines and treatment by a psychiatrist were associated with an increased risk of becoming a long-term user.Conclusion. Both the prevalence and the incidence of the use of SSRIs increased during the 1990s. This can be explained by both the larger number of patients starting on an antidepressant and the longer continuation of the treatment. During the follow-up period, 30% of the patients became a long-term user at one time or another.</p
