RESUMEN
Background: Asynchronous telemedicine (ATM), which describes telemedical interaction between a patient and provider where neither party communicates simultaneously, is an important telemedicine modality that is seeing increased use. In this article, we summarize the published peer-reviewed literature specifically related to ATM to (1) identify terms or phrases that are used to describe ATM, (2) ascertain how this research has thus far addressed the various aspects of the quadruple aim of medicine, and (3) assess the methodological rigor of research on ATM. We also divided the literature into pre- and post-COVID-19 onset periods to identify potential variations in the literature between these two periods. Methods: This systematic literature review follows the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. The literature search, utilizing multiple databases and applying inclusion and exclusion criteria, initially produced 2624 abstracts for review. De-duplication and screening ultimately yielded 104 articles for data extraction. Results: "Store-and-forward" and variations of "e-visit" were the most frequently used alternative terms for ATM. Care quality was the most frequently addressed aspect of the Quadruple Aim of Medicine-more than double any other category-followed by patient satisfaction. We separated cost of care into two categories: patients' cost of care and providers' cost to provide care. Patient cost of care was the third most addressed aspect of the Quadruple Aim of Medicine followed by provider well-being and provider's cost to provide care. Methodological rigor of the studies was also addressed, with only 2 quantitative studies ranked "Strong," 5 ranked "Moderate," and 97 ranked "Weak." Qualitative studies were generally acceptable but struggled methodologically with accounting for all participants and articulation of results. Conclusions: Although "store-and-forward" is somewhat more frequently used in the studies included in this review, variants of "e-visit," are growing in recent usage. Given the relative newness of modality, it is not surprising that quality of care is the most researched aspect of the Quadruple Aim of Medicine in ATM research. We anticipate more balance between these areas as research in this field matures. Primary areas of research need currently relate to practitioners-specifically their costs of providing care and well-being. Finally, future ATM research needs to address research challenges of selection bias and blinding in quantitative studies and improved participant tracking and articulation of both study design and results in qualitative studies.
RESUMEN
BACKGROUND: Clinical practice guidelines recommend 40-60 mg of prednisone equivalent for 10-14 days for patients with acute exacerbations of chronic obstructive pulmonary disease (COPD). However, the amount of corticosteroid prescribed varies widely in clinical practice. Using the electronic health record, we implemented an evidence-based order set to standardize treatment of patients hospitalized with acute exacerbations of COPD. METHODS: This is a pre- and post-intervention study on patients hospitalized between January 1, 2009 and September 30, 2012 with primary discharge diagnosis of COPD (International Classification of Diseases, 9(th) Revision code: 491.xx, 492.xx, and 496) and receipt of at least one dose of corticosteroid at our tertiary care hospital. Data on baseline demographics, dose of corticosteroid in prednisone equivalent administered during the first 48 hours and during the entire hospitalizations were collected from the electronic health record. Evidence-based guidelines were used to build and implement acute exacerbations of COPD management electronic ordersets in our electronic health record, Epic (Verona, WI). We divided the study into 2 time periods (January 1, 2009 through February 28, 2011 as pre- [n = 203] and March 1, 2011 through September 30, 2012 as post-intervention periods [n = 217]). The primary outcome measure was corticosteroid dose administered in the first 48 hours. Secondary outcome measures were corticosteroid dosage during the entire hospitalization, length of stay, hospital follow-up rates, and 30-day readmission rates. RESULTS: A total of 420 patients with acute exacerbations of COPD were included in the study. In the post-intervention period, the median amount of corticosteroid used in the first 48 hours was significantly reduced (306.2 mg vs 156.25 mg, P < .0001), as was that used during the entire hospitalization (352.5 mg vs 175 mg, P < .0001). There was no difference in hospital follow-up rates, length of stay, or 30-day readmission rates between the 2 periods. CONCLUSIONS: Evidence-based electronic ordersets improve compliance with clinical practice guidelines and reduce the total dose of corticosteroid administered in patients hospitalized with acute exacerbations of COPD.
