Dose-Dependent Association between Sarcopenia and Moderate-To-Severe Thoracic Vertebral Fragility Fracture in Older Adults.

INTRODUCTION: Sarcopenia and vertebral fracture affect a large number of older adults and can be debilitating. However, the correlation between sarcopenia and vertebral fracture has not been well studied. Thus, this study investigates the correlation between vertebral fragility fracture and the severity of sarcopenia. METHOD: This cross-sectional study included 300 community-dwelling older adults with risk higher than 10-year probability of 3% for a hip fracture and 20% for a major osteoporotic fracture by FRAX score. Sarcopenia was defined according to the Asian Working Group for Sarcopenia consensus. Bone mineral density (BMD) was classified into normal or abnormal groups (T score ≤ -1.0) according to WHO criteria. Vertebral fracture was graded mild, moderate, and severe by a standardized semi-quantitative method. The association between sarcopenia and vertebral fragility fracture was investigated using a logistic regression model adjusted for confounding factors. RESULTS: Compared with the normal BMD group, the abnormal BMD group had a significantly higher prevalence of sarcopenia (7.4 vs. 26.6%, p < 0.001), poorer muscle mass (p < 0.001), and poorer hand grip (p < 0.001). The prevalence of moderate-to-severe fracture was significantly different (p = 0.006) among severe sarcopenia (16.7%), sarcopenia (6.9%), and non-sarcopenia (3.7%) for thoracic vertebrae. In the logistical regression model adjusted for confounding factors, sarcopenia plus severe sarcopenia was identified as a risk factor for moderate-to-severe thoracic vertebral fragility fracture (odds ratio [OR] = 3.29, 95% CI: 1.23-8.78, p = 0.018). We further classified the participants into normal, sarcopenia, and severe sarcopenia and found that sarcopenia and severe sarcopenia had a dose-dependent association with prevalence of thoracic vertebral fragility fractures with ORs of 2.56 (95% CI: 0.66-9.91) and 4.04 (95% CI: 1.24-13.20), respectively; p for trend = 0.014. CONCLUSION: Sarcopenia is a potential risk factor for and has a dose-dependent association with moderate-to-severe thoracic fragility fracture in older adults at increased risk for fractures.

Awareness of, attitude toward, and willingness to participate in pay for performance programs among family physicians: a cross-sectional study.

BACKGROUND: The National Health Insurance Administration of Taiwan has introduced several pay-for-performance programs to improve the quality of healthcare. This study aimed to provide government with evidence-based research findings to help primary care physicians to actively engage in pay-for-performance programs. METHODS: We conducted a questionnaire survey among family physicians with age-stratified sampling from September 2016 to December 2017. The structured questionnaire consisted of items including the basic demographics of the surveyee and their awareness of and attitudes toward the strengths and/or weaknesses of the pay-for-performance programs, as well as their subjective norms, and the willingness to participate in the pay-for-performance programs. Univariate analysis and multivariate logistic regression analysis were performed to compare the differences between family physicians who participate in the pay-for-performance programs versus those who did not. RESULTS: A total of 543 family physicians completed the questionnaire. Among family physicians who participated in the pay-for-performance programs, more had joined the Family Practice Integrated Care Project [Odds ratio (OR): 2.70; 95% Confidence interval (CI): 1.78 ~ 4.09], had a greater awareness of pay-for-performance programs (OR: 2.37; 95% CI: 1.50 ~ 3.83), and a less negative attitude to pay-for-performance programs (OR: 0.50; 95% CI: 0.31 ~ 0.80) after adjusting for age and gender. The major reasons for family physicians who decided to join the pay-for-performance programs included believing the programs help enhance the quality of healthcare (80.8%) and recognizing the benefit of saving health expenditure (63.4%). The causes of unwillingness to join in a pay-for-performance program among non-participants were increased load of administrative works (79.6%) and inadequate understanding of the contents of the pay-for-performance programs (62.9%). CONCLUSIONS: To better motivate family physicians into P4P participation, hosting effective training programs, developing a more transparent formula for assessing financial risk, providing sufficient budget for healthcare quality improvement, and designing a reasonable profit-sharing plan to promote collaboration between different levels of medical institutions are all imperative.
