Background: This research evaluates the effect of hospital competition on inward and outward patient transfers for different types of payers including the uninsured. Although it is a less spotlighted issue, an equally important topic is the likelihood of inter-hospital patient transfers of the insured and the uninsured. This study attempts to fill a gap in the research about the relationship between hospital competition and patient transfers.

Methods: By developing the payer-specific level of hospital competition, this research evaluates the effect of hospital competition on inward and outward patient sharing (or patient transfers) for different types of payers including the uninsured. For patient transfers, instead of focusing on whether a patient is transferred from one hospital to another hospital at the patient level, we measure the numbers of patient transfers between hospitals (both inward and outward) at the hospital level. These dependent variables-the numbers of outward and inward patient transfers by the principal payers-are count variables, and we employ either a Poisson regression model or a negative binomial regression model.

Results: Controlling for hospital characteristics, when the uninsured Hirschman-Herfindahl Index (HHI) increased by 0.01, the uninsured were 593 % more likely to be transferred to another hospital. When a hospital dominates its market, it tends to expel uninsured patients to other hospitals.

Conclusion: If patient transfers are medically unnecessary and primarily due to financial incentives, health administrators and policymakers should minimize such events. Since the uninsured who are admitted to a hospital that dominates its hospital market are likely to be much more vulnerable in their access to health care services, the state government of Florida needs to move toward increased health insurance coverage for eligible Floridians.

Obstructive sleep apnea (OSA) is widespread, under-recognized, and under-treated, impacting the health and quality of life for millions. The current gold standard for sleep apnea testing is based on the in-lab sleep study, which is costly, cumbersome, not readily available and represents a well-known roadblock to managing this huge societal burden. Assessment of neuromuscular function involved in the upper airway using electromyography (EMG) has shown potential to characterize and diagnose sleep apnea, while the development of transmembranous electromyography (tmEMG), a painless surface probe, has made this opportunity practical and highly feasible.

Research Question: What number of retrieved oocytes is associated with the optimum chance of achieving a live birth for women undergoing ovarian stimulation with individualized follitropin delta?

Design: An individual patient data meta-analysis was performed on 1772 patients from five randomized controlled trials using individualized follitropin delta for ovarian stimulation with fixed daily dosing based on serum anti-Müllerian hormone (AMH) level and body weight. Live birth rate (LBR) and ovarian hyperstimulation syndrome (OHSS) were evaluated in relation to the number of oocytes retrieved. Predicted LBR was obtained using a logistic regression analysis with fractional polynomials.

Objective: To analyse the interrater reliability of the NEUMOBACT checklist and verify whether consistent results are reproducible.

Methods: A validation study with a cross-sectional design, compliant with the GRRAS checklist, among ICU nurses attending a SIMULAZERO course with an Objective Structured Clinical Evaluation simulation format, to verify transfer from theory to clinical practice of knowledge and skills in ventilator-associated pneumonia (VAP) and catheter-related bacteraemia (CRB) prevention. A minimum sample size of 111 pairs of nurse raters was calculated.

Background: Nerve wraps composed of various autologous and bioengineered materials have been used to bolster nerve repair sites. In this study, we describe the novel use of autologous fascia nerve wraps (AFNW) as an adjunct to epineurial repair and evaluate their effect on inflammatory cytokine expression, intraneural collagen deposition and end-organ reinnervation in rats and use of AFNW in a patient case series.

Methods: Lewis rats received sciatic transection with repair either with or without AFNW, sciatic-to-common peroneal nerve transfer with or without AFNW, or sham surgery (n=14/group).
