Big data analysis techniques to address polypharmacy in patients – a scoping review

Abstract

Background: Polypharmacy is a key challenge in healthcare especially in older and multimorbid patients. The use of multiple medications increases the potential for drug interactions and for prescription of potentially inappropriate medications. eHealth solutions are increasingly recommended in healthcare, with big data analysis techniques as a major component. In the following we use the term analysis of big data as referring to the computational analysis of large data sets to find patterns, trends, and associations in large data sets collected from a wide range of sources in contrast to using classical statistics programs. It is hypothesized that big data analysis is able to reveal patterns in patient data that would not be identifiable using conventional methods of data analysis. The aim of this review was to evaluate whether there are existing big data analysis techniques that can help to identify patients consuming multiple drugs and to assist in the reduction of polypharmacy in patients. Methods: A computerized search was conducted in February 2019 and updated in May 2020, using the PubMed, Web of Science and Cochrane Library databases. The search strategy was defined by the principles of a systematic search, using the PICO scheme. All studies evaluating big data analytics about patients consuming multiple drugs were considered. Two researchers assessed all search results independently to identify eligible studies. The data was then extracted into standardized tables. Results: A total of 327 studies were identified through the database search. After title and abstract screening, 302 items were removed. Only three studies were identified as addressing big data analysis techniques in patients with polypharmacy. One study extracted antipsychotic polypharmacy data, the second introduced a decision support system to evaluate side-effects in patients with polypharmacy and the third evaluated a decision support system to identify polypharmacy-related problems in individuals. Conclusions: There are few studies to date which have used big data analysis techniques for identification and management of polypharmacy. There may be a need to further explore interdisciplinary collaboration between computer scientists and healthcare professionals, to develop and evaluate big data analysis techniques that can be implemented to manage polypharmacy.

An Update on Medication Use in Older Adults: a Narrative Review

“…For example, a recent study has identified a core set of 12 indicators of clinical importance considered relevant to polypharmacy appropriateness which could be used to target and monitor future polypharmacy i n t e r v e n t i o n s [1 01 ]. I t ha s be en su gge ste d th at pharmacogenomics might help in individualised deprescribing in older adults [102], whilst machine learning and big data analysis techniques have been used to predict, identify, and manage polypharmacy [103,104]. It will be interesting to see how these areas may help to progress the field over the coming decades.…”

A Machine-Assisted Gaze Analysis Method for Students’ Psychological Evaluation

“…The literature [10] believes that mentally healthy people often have 7 characteristics, which are generally reasonable, have a sense of self-growth, have the ability to love, have good intimacy, adapt to reality, work well, and have the ability to have a better life. Literature [11] puts forward 10 criteria for mental health: adequate self-safety, understand-ing of one's own abilities, goals are in line with reality, not divorced from society, healthy personality, able to learn from experience, good interpersonal relationships, control one's emotions, give full play to one's own personality, and meet personal needs. Literature [12] believes that a mentally healthy person, that is, a mature person, should possess 15 abilities and characteristics including self-sense, independence, dependence, adaptation, reality testing, the ability to love and be loved, and the ability to control emotions.…”
