Assessing the Estimands and Estimates of Hospitalization Rates in Health Economics and Clinical Medicine

Health Economics, EarlyView.
ABSTRACT Even though data on hospital admissions are widely used in health research, hospitalization‐related estimands measured using these data are not always clearly conceptualized. Consequently, estimators of these quantities can have unclear rationales and undesirable properties.

Explainable one-class feature extraction by adaptive resonance for anomaly detection in quality assurance.

PLoS ONE
In this study, we address the inherent challenges in radiotherapy (RT) plan quality assessment (QA). RT, a prevalent cancer treatment, utilizes high-energy beams to target tumors while sparing adjacent healthy tissues.

Retrospective dosimetry study of intensity-modulated radiation therapy for nasopharyngeal carcinoma: measurement-guided dose reconstruction and analysis

Radiation Oncology, 2018
Background Conventional phantom-based planar dosimetry (2D-PBD) quality assurance (QA) using gamma pass rate (GP (%)) is inadequate to reflect clinically relevant dose error in intensity-modulated radiation therapy (IMRT), owing to a lack of information ...

Perceptions and experiences of midwives' regarding the use of the labor care guide at two state hospitals in Khomas region, Namibia

International Journal of Gynecology &Obstetrics, EarlyView.
Abstract The labor care guide (LCG) is a new tool for monitoring labor, introduced to replace the partograph, which had been used improperly and inconsistently across various contexts. Early research suggests that healthcare practitioners view the LCG as a tool that enhances the quality of care during labor and delivery.
