Objectives: To compare the total medical costs associated with operative versus non-operative medical procedures for femoral neck fractures in older adults with Alzheimer's disease (AD).
Methods: This retrospective cohort study examined 4,157 Optum beneficiaries diagnosed with AD who filed an initial claim for femoral neck fracture between January 1, 2012, and December 31, 2017. Generalized linear regression with Gamma log link function was performed to evaluate total medical costs between surgical treatment and non-operative care while controlling for covariates.
Article Synopsis
- This study assesses the cost-effectiveness of mobile stroke units (MSUs) compared to standard emergency medical services (EMS) for administering thrombolytics in ischemic stroke patients.
- The analysis used the incremental cost-effectiveness ratio (ICER) method to evaluate healthcare costs and quality-adjusted life years (QALYs), highlighting considerable variations based on patient disability status and treatment costs.
- Overall, while MSUs show borderline cost-effectiveness for all eligible patients, they are more favorable for patients without pre-existing disabilities, particularly when focusing on lifetime costs and stroke-specific expenses.
Latent classification model is a class of statistical methods for identifying unobserved class membership among the study samples using some observed data. In this study, we proposed a latent classification model that takes a censored longitudinal binary outcome variable and uses its changing pattern over time to predict individuals' latent class membership. Assuming the time-dependent outcome variables follow a continuous-time Markov chain, the proposed method has two primary goals: (1) estimate the distribution of the latent classes and predict individuals' class membership, and (2) estimate the class-specific transition rates and rate ratios.

Accordingly, the study examined the association between lifestyle and colonoscopy screening in Hispanic adults along the Texas-Mexico border, where there is suboptimal colorectal cancer prevention.
Methods: Lifestyle behavior adherence and compliance with colonoscopy screening schedules were assessed using 2013-2023 data from the Cameron County Hispanic Cohorta population-based sample of Hispanic adults living along the Texas-Mexico border.
Introduction: Addressing femoral neck fractures resulting from ground-level falls in older adults with Alzheimer's disease (AD) involves a personalized treatment plan. There is considerable ongoing debate concerning the relative advantages and disadvantages of surgical treatment (internal fixation or arthroplasty) vs nonoperative treatment for femoral neck fractures in older persons with AD.
Methods: This retrospective cohort study compared the mortality, hazard ratio, and survival rate between operative and nonoperative treatments, controlling for patients' demographic information and baseline health status.
