Appropriateness and Cost-Effectiveness of Echocardiograms Ordered by Pediatric Cardiologists and Primary Care Providers for Syncope.

The pediatric appropriate use criteria (AUC) were applied to transthoracic echocardiograms (TTE) ordered by primary care providers (PCPs) and pediatric cardiologists for the diagnosis of syncope to compare appropriateness ratings and cost-effectiveness. Included were patients ≤18 years of age from October 2016 to October 2018 with syncope who underwent initial outpatient pediatric TTE ordered by a PCP or were seen in Pediatric Cardiology clinic. Ordering rate of TTE by pediatric cardiologists, AUC classification, and TTE findings were obtained. PCPs ordered significantly more TTEs than pediatric cardiologists for "rarely appropriate" indications (61.5% vs 7.5%, P < .001). Cardiologists ordered TTEs at 17.2% of visits. Using appropriateness as a marker of effect, with the incremental cost-effectiveness ratio, it was more cost-effective ($543.33 per patient) to refer to a pediatric cardiologist than to order the TTE alone. This suggests that improved PCP education of the AUC and appropriate indications of TTEs for syncope may improve cost-effectiveness when using order appropriateness as a marker of effectiveness.

Systems Thinking and Systems-Based Practice Across the Health Professions: An Inquiry Into Definitions, Teaching Practices, and Assessment.

Phenomenon: Systems thinking is the cornerstone of systems-based practice (SBP) and a core competency in medicine and health sciences. Literature regarding how to teach or apply systems thinking in practice is limited. This study aimed to understand how educators in medicine, physical therapy, physician assistant, nursing, and speech-language pathology education programs teach and assess systems thinking and SBP. APPROACH: Twenty-six educators from seven different degree programs across the five professions were interviewed and program descriptions and relevant course syllabi were reviewed. Qualitative analysis was iterative and incorporated inductive and deductive methods as well as a constant comparison of units of data to identify patterns and themes. FINDINGS: Six themes were identified: 1) participants described systems thinking as ranging across four major levels of healthcare (i.e., patient, care team, organization, and external environment); 2) participants associated systems thinking with a wide range of activities across the curriculum including quality improvement, Inter-professional education (IPE), error mitigation, and advocacy; 3) the need for healthcare professionals to understand systems thinking was primarily externally driven; 4) participants perceived that learning systems thinking occurred mainly informally and experientially rather than through formal didactic instruction; 5) participants characterized systems thinking content as interspersed across the curriculum and described a variety of strategies for teaching and assessing it; 6) participants indicated a structured framework and inter-professional approach may enhance teaching and assessment of systems thinking. Insights: Systems thinking means different things to different health professionals. Teaching and assessing systems thinking across the health professions will require further training and practice. Tools, techniques, taxonomies and expertise outside of healthcare may be used to enhance the teaching, assessment, and application of systems thinking and SBP to clinical practice; however, these would need to be adapted and refined for use in healthcare.

Greater improvement in cardiorespiratory fitness using higher-intensity interval training in the standard cardiac rehabilitation setting.

PURPOSE: We tested the hypothesis that higher-intensity interval training (HIIT) could be deployed into a standard cardiac rehabilitation (CR) setting and would result in a greater increase in cardiorespiratory fitness (ie, peak oxygen uptake, (·)VO2) versus moderate-intensity continuous training (MCT). METHODS: Thirty-nine patients participating in a standard phase 2 CR program were randomized to HIIT or MCT; 15 patients and 13 patients in the HIIT and MCT groups, respectively, completed CR and baseline and followup cardiopulmonary exercise testing. RESULTS: No patients in either study group experienced an event that required hospitalization during or within 3 hours after exercise. The changes in resting heart rate and blood pressure at followup testing were similar for both HIIT and MCT. (·)VO2 at ventilatory-derived anaerobic threshold increased more (P < .05) with HIIT (3.0 ± 2.8 mL·kg⁻¹·min⁻¹) versus MCT (0.7 ± 2.2 mL·kg⁻¹·min⁻¹). During followup testing, submaximal heart rate at the end of stage 2 of the exercise test was significantly lower within both the HIIT and MCT groups, with no difference noted between groups. Peak (·)VO2 improved more after CR in patients in HIIT versus MCT (3.6 ± 3.1 mL·kg⁻¹·min⁻¹ vs 1.7 ± 1.7 mL·kg⁻¹·min⁻¹; P < .05). CONCLUSIONS: Among patients with stable coronary heart disease on evidence-based therapy, HIIT was successfully integrated into a standard CR setting and, when compared to MCT, resulted in greater improvement in peak exercise capacity and submaximal endurance.

Building empowering partnerships for interprofessional care.

While partnership approaches have the potential to achieve cost-effective quality health care, several attributes of the current context make partnerships difficult to achieve. This paper provides an analysis of the socio-cultural, structural and human challenges to building partnerships at both personal and organizational levels, together with an empowering interdisciplinary approach for overcoming these barriers. Premised on empirical evidence, 'flexible client-driven care', currently being tested in the home care sector in Canada, encompasses structures and processes that promote relationship-building and conscientious critical application of individual and collective potential for achieving health care. Strategies for implementing empowering partnership-building at both personal and organizational levels are elaborated, together with the challenges encountered. The practical issues addressed afford insights and ideas for others who may be attempting to achieve similar partnership aims.
