Adverse drug reactions in elderly people : the challenge of safer prescribing

Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed

Full text linkWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods

No full textA systematic review of the outcomes reported in trials of medication review in older patients: the need for a core outcome set
Full text linkAIM: Medication review has been advocated as one of the measures to tackle the
challenge of polypharmacy in older patients, yet there is no consensus on how
best to evaluate its efficacy. This study aimed to assess outcome reporting in
trials of medication review in older patients.
METHODS: Randomized controlled trials (RCTs), prospective studies and RCT
protocols involving medication review performed in patients aged 65 years or
older in any setting of care were identified from: (1) a recent systematic
review; (2) RCT registries of ongoing studies; (3) the Cochrane library. The
type, definition, and frequency of all outcomes reported were extracted
independently by two researchers.
RESULTS: Forty-seven RCTs or prospective published studies and 32 RCT protocols
were identified. A total of 327 distinct outcomes were identified in the 47
published studies. Only one fifth (21%) of the studies evaluated the impact of
medication reviews on adverse events such as drug reactions or drug-related
hospital admissions. Most of the outcomes were related to medication use
(n = 114, 35%) and healthcare use (n = 74, 23%). Very few outcomes were
patient-related (n = 24, 7%). A total of 248 distinct outcomes were identified in
the 32 RCT protocols. Overall, the number of outcomes and the number and type of
health domains covered by the outcomes varied largely.
CONCLUSION: Outcome reporting from RCTs concerning medication review in older
patients is heterogeneous. This review highlights the need for a standardized
core outcome set for medication review in older patients, to improve outcom
Pragmatic Case Studies as a Source of Unity in Applied Psychology
No full textTo unify or not to unify applied psychology: that is the question. In this article we review pendulum swings in the historical efforts to answer this question—from a comprehensive, positivist, “top-down,” deductive yes between the 1930s and the early 60s, to a postmodern no since then. A rationale and proposal for a limited, “bottom-up,” inductive yes in applied psychology is then presented, employing a case-based paradigm that integrates both positivist and postmodern themes and components. This paradigm is labeled “pragmatic psychology” and, its specific use of case studies, the “Pragmatic Case Study Method” (“PCS Method”). We call for the creation of peer-reviewed journal-databases of pragmatic case studies as a foundational source of unifying applied knowledge in our discipline. As one example, the potential of the PCS Method for unifying different angles of theoretical regard is illustrated in an area of applied psychology, psychotherapy, via the case of Mrs. B. The article then turns to the broader historical and epistemological arguments for the unifying nature of the PCS Method in both applied and basic psychology.Peer reviewe

Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
