Physician Experience with Electronic Order Sets.

BACKGROUND: Electronic medical record (EMR) and electronic health record (EHR) are used interchangeably to describe a computerized medical information system that collects, stores and displays patient information (Boonstra and Broekhuis 2010). Blumenthal and Tavenner (2010) suggested that computerized medical implementation improves decision-making and patient management. As part of its EMR, Humber River Hospital has implemented electronic order sets (EOSs) by building them into the computerized physician order entry (CPOE) system. Electronic prescribing renders paper prescriptions obsolete as it reduces errors; increases accuracy; and enhances efficiency, compliance and record-keeping (Canada Health Infoway 2017). OBJECTIVE: The aim of this research was to explore physicians' perspectives and experiences using EOSs. METHODS: This qualitative study examined the perceptions of various physicians on the impact of EOSs. Data were collected through semi-structured, in-depth interviews with eligible physicians. Domains explored included usability, efficiency, safety and implications for the physician profession. RESULTS: Major themes that emerged included usability, efficiency and safety. Several implications for physician practice were also revealed. CONCLUSION: The findings from our study support previous studies that describe the benefits of EOSs, including ease of use and efficiency, real-time information that is evidence-based, increased safety and minimization of memory burden. EOSs were not perceived to be a replacement for clinical reasoning.

Sex Difference in Clinical Outcome of Patients With Implantable Cardioverter-defibrillator.

BACKGROUND: Indications for the use of the Implantable Cardioverter-Defibrillator (ICD) have been greatly expanded in recent years, but the influence of sex on the efficacy of the ICD in eligible patients has still been remained unknown. OBJECTIVES: The aim of this study was to determine the impact of sex on the effectiveness of the ICD intervention for mortality and appropriate events. MATERIALS AND METHODS: This retrospective study was conducted on the outcome of the ICD therapy in 443 patients, including 341 men with a mean age of 55 ± 16 years and 102 women with a mean age of 54 ± 17 years, in our center between April 2001 and February 2007. Sex-specific cumulative probabilities of outcomes concerning mortality and appropriate ICD intervention were evaluated for the patients. RESULTS: Among the 443 patients, enrolled in this study, the women and men had a mean left ventricular ejection fraction of 35 ± 14.8% and 30 ± 13.5%, respectively (P = 0.03). Ischemic heart disease was more frequent in the men than the women (P = 0.0001).The average follow-up period was 3 years. Test for an interaction between sex and the ICD treatment regarding total mortality was not significant (23 men and 6 women). Additionally, there was no significant difference in appropriate events between the women and men (129 men and 33 women). CONCLUSIONS: While women were significantly less likely than the men to receive the ICD therapy, no conclusive evidence could be found for the impact of sex factor on the effectiveness of the ICD intervention with respect to mortality and appropriate events.
