Stapedotomy is an effective treatment for conductive hearing loss associated with otosclerosis. However, the procedure, especially using the endoscopic technique requires extensive training and experience for optimal results. Due to limited training options in endoscopic stapes surgery, we aim to develop an ovine stapedotomy model and assess its feasibility for surgeons at different training levels.

A fully endoscopic ovine laser-stapedotomy model was developed and described. During repetitive dissections, surgical time required for the different steps to assess the training curve and associated intraoperative complications were recorded in three surgeons of different training level. Additionally, subjective feedback was assessed.

Successful endoscopic laser-stapedotomy was performed in 25 cases in the ovine model. Assessment of surgical time revealed a stable curve for the experienced surgeon (mean 1501 min) for the whole training with no intraoperative complications. The fellow showed a gradual reduction of surgical time from 2721 (first five cases) to 2410 minutes (last five cases) and the resident a reduction from 4238 to 2108 minutes respectively. The assessed learning curve for the trainees revealed a significant association between the operative time and observed intraoperative complications.

In this study, an ex-vivo model for exclusively endoscopic laser-stapedotomy was developed and tested for feasibility. We suggest the ovine model as a cost-effective, easily available, and realistic training model for future otologic surgeons. The surgeons were able to improve their performance with satisfactory results despite the small number of cases.

Health care expenditures in the United States are high and rising, with significant increases over the decades. The delivery, organization, and financing of the health care system has evolved over time due to technological innovation, policy changes, patient preferences, altering payment mechanisms, shifting demographics, and other factors.

The objective of this study was to examine trends over time in health care utilization and expenditures in the United States.

This analysis employs descriptive statistics to examine 5 decades of health care utilization and expenditure data from the Agency for Healthcare Research and Quality (AHRQ) for 1977-2017.

Measures include utilization and expenditures (not charges) for inpatient, emergency department, outpatient physician, outpatient nonphysician, office-based physician, dental, and out-of-pocket retail prescription drugs.

We demonstrate that while health care expenditures have increased significantly overall and by type of care, utilization trends are less pronounced. The population of the United States grew 53% between 1977 and 2017, while annual total expenditures on health care increased by 208%. selleck kinase inhibitor Amidst attention to out-of-pocket exposure for unexpected medical care bills, out-of-pocket payments for care have declined from 32% in 1977 to 12% in 2017 but increased in amount.

This article provides the first extended snapshot of the dynamics of health care utilization and expenditures in the United States. Aspects of health care are much different today than in previous decades, yet the inpatient setting still dominates the expenditures.

A measure of episode spending, such as Medicare Spending Per Beneficiary (MSPB) is increasingly used to evaluate provider performance. Yet if the measure is unreliable, as is often true for low-volume providers, it cannot distinguish "good" from "poor" performance.

The objective of this study was to evaluate the reliability of a uniformly calculated MSPB measure for post-acute care (PAC) and the tradeoffs involved in setting a minimum case count threshold.

Medicare claims for 15 million PAC episodes from April 2013 to March 2015.

Given the overlap in patients treated in PAC settings, we developed a uniformly calculated MSPB measure for PAC providers that measures spending during the PAC stay and the following 30 days. We examine variation in the MSPB-PAC measure and characterize the measure's reliability and its relationship to provider case counts.

Applied to our MSPB-PAC measure, a minimum threshold of 20 Medicare episodes as currently used by the Centers for Medicare & Medicaid Services (CMS)d drawing incorrect conclusions about low-volume providers.Hospitalized adult patients often require more than 1 short peripheral catheter (SPC) to complete the prescribed intravenous (IV) therapy attributed to catheter failure and the practice of routinely replacing SPCs. The purpose of this quality improvement project was to increase the number of SPCs that dwell for the complete duration of the IV therapy in hospitalized adult patients using a bundled approach. Implementation of an engineered securement device (ESD), education pertaining to modifiable risk factors, and changing the practice to removal on clinical indication were methods used to reduce the number of SPC insertions and catheter failures. This study was conducted at a rural Midwestern hospital using a convenience sample (N = 405) and an observational, descriptive cohort design in 6 phases between September 2019 and March 2020. After the practice changes, there was a reduction of SPC replacement (24%), catheter failures (24% to 13%), SPCs per patient (M = 2.9-2.2; P = .045), SPC insertions (4000 per year), and catheter-related bloodstream infections (0.26 per 1000 catheter days to 0.0), as well as a significant increase of SPCs remaining in situ (M = 2.6-3.8 days; P less then .001), resulting in an estimated cost savings of at least $285,000. The results demonstrated that the risk of failure significantly increased when SPCs were inserted in the wrist (P = .007) and upper arm (P = .026) and significantly reduced when inserted in the forearm (P = .39). Study findings suggest that using an ESD, promoting SPC insertion in the forearm, avoiding the wrist and upper arm, and changing practice to removal when clinically indicated reduced the number of SPC insertions and rate of catheter failures.
