The sample dimension, types of variables, format used for measurement, and construction of instruments to collect valid and reliable data must be considered during the research process. In the social and health sciences, and more specifically in nursing, data-collection instruments are usually composed of latent variables or variables that cannot be directly observed. Such facts emphasize the importance of deciding how to measure study variables (using an ordinal scale or a Likert or Likert-type scale). Psychometric scales are examples of instruments that are affected by the type of variables that comprise them, which could cause problems with measurement and statistical analysis (parametric tests versus non-parametric tests). Hence, investigators using these variables must rely on suppositions based on simulation studies or recommendations based on scientific evidence in order to make the best decisions.

Background: Patients with complex valvular heart disease (VHD) should be evaluated by a multidisciplinary heart team (HT). In low- and middle-income countries, referral practices are more variable, permitting any physician to refer patients directly to a cardiac surgeon without prior formal evaluation by a cardiologist with expertise in VHD.
Objectives: The goal of the study was to examine the demographics of VHD patients seen in a large heart valve center in a low- and middle-income country and to assess the impact of the multidisciplinary HT in patients referred for valve surgery.

Introduction: The emergency physician (EP) workforce has been a recent focus after a workforce projection predicted a surplus of EPs by 2030. A previous study of Iowa emergency departments (EDs) demonstrated wide variability in ED staffing patterns and attributed it to the lack of EP job candidates. With the recent increase in emergency medicine (EM) residency positions, the objectives of this study were to understand how Iowa ED physician staffing has changed in regard to presence of board-certified EPs and what operational differences in Iowa EDs may be associated with staffing to provide insight into what may be occurring in other predominantly rural states.

Purpose: Identifying patients who may benefit from multiple drilling are crucial. Hence, the purpose of the study is to utilize radiomics and deep learning for predicting no-collapse survival in patients with femoral head osteonecrosis.
Methods: Patients who underwent multiple drilling were enrolled.

Background Context: Clinical outcomes are directly related to patient selection and treatment indications for improved quality of life. With emphasis on quality and value, it is essential that treatment recommendations are optimized.
Purpose: The purpose of the North American Spine Society (NASS) Appropriate Use Criteria (AUC) is to determine the appropriate (ie, reasonable) multidisciplinary treatment recommendations for patients with metastatic neoplastic vertebral fractures across a spectrum of more common clinical scenarios.
