Integrating digital interventions in healthcare has gained increasing popularity among clinical pharmacists (CPs) due to advances in technology. The purpose of this study was to systematically review CP-led digital interventions to improve patients’ health-related clinical outcomes. PubMed and the Cochrane Database were searched to select studies that had conducted a randomized controlled trial to evaluate clinical outcomes in adults following a CP-led digital intervention for the period from January 2005 to August 2021. A total of 19 studies were included in our analysis. In these 19 studies, the most commonly used digital intervention by CPs was telephone use (n = 15), followed by a web-based tool (n = 2) and a mobile app (n = 2). These interventions were provided to serve a wide range of purposes in patients’ outcomes: change in lab values (e.g., blood pressure, HbA1c) (n = 23), reduction in health service use (n = 8), enhancing adherence (n = 6), improvement in drug-related outcomes (n = 6), increase in survival (n = 3), and reduction in health-related risk (e.g., CVD risk) (n = 2). Although the impacts of telephone-based interventions on patients’ outcomes were decidedly mixed, web-based interventions and mobile apps exerted generally positive influences. To date, little research has investigated the cost-effectiveness of digital interventions. Future studies are warranted.
Objective: The study purpose was to critically review FDA-issued warning letters (WLs) and notice of violation (NOV) letters against drug companies’ from 2012-2019 for economic, clinical, and humanistic (ECHO) claims made in pharmaceutical promotional materials. Specific objectives were to assess the, (1) number of WLs and NOV issued; (2) frequency of WLs and NOV by therapeutic areas; (3) type of communication media cited in WLs or NOV; (4) intended audience for the claims in promotional materials for which the WLs and NOV were issued; and (5) number of WLs and NOV for ECHO claims.
Methods: The quantitative content analysis approach was employed to review WLs and NOVs, obtained from the FDA website, from January 2012-December 2019. A data abstraction form was created based on the published literature on this topic and assessment of the content of WLs and NOVs for 2010. This form was pilot tested on letters issued in 2011. The researchers discussed any unclear question or information presented in the letters. The letters were reviewed three researchers. If there was disagreement between the reviewers, either a fourth reviewer arbitrated on the disagreement or the letter(s) were discussed by the researchers to determine a final classification. ICD-10 codes were used for therapeutic categories in the data collected form. Descriptive statistics, Kappa statistics for interrater reliability, and Cochrane-Armitage test were performed using IBM SPSS Statistics version 24.0
Results: A total of 102 letters were analyzed. Of these, 19 (19%) were WLs and 83 (81%) were NOVs. Majority of these letters were issued to manufacturers of therapeutic agents for diseases of the nervous system (n=15; 14.7%) and neoplasms (n=15; 14.7%). The most commonly cited media for violation was online website (n=29; 27.1%). Out of the 153 violations in 102 letters, 92 (60.1%) were clinical; 13 (8.5%) humanistic; 2 (1.3%) were economic; and 46 (30%) were categorized as ‘Others’.
Conclusion: The study found misleading claims of the clinical effectiveness and risk information included in the promotional materials targeted to consumers as well as healthcare providers. Promoting reliable, evidence-based information is important for the health of the public as inadequate information could lead to irrational decision making both on consumer as well as on prescriber side.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
