Combined Functional Assessment for Predicting Clinical Outcomes in Stroke Patients After Post-acute Care: A Retrospective Multi-Center Cohort in Central Taiwan.

Background and Objective: In 2014, Taiwan's National Health Insurance administration launched a post-acute care (PAC) program for patients to improve their functions after acute stroke. The present study was aimed to determine PAC assessment parameters, either alone or in combination, for predicting clinical outcomes. Methods: We retrospectively enrolled stroke adult patients through one PAC network in central Taiwan between January 2014 and December 2020. We collected data on post-stroke patients' functional ability at baseline and after PAC stay. The comprehensive assessment included the following: Modified Rankin Scale (MRS), Functional Oral Intake Scale (FOIS), Mini-Nutritional Assessment (MNA), Berg Balance Scale (BBS), Fugl-Meyer Assessment (FMA), Mini-Mental State Examination (MMSE), aphasia test, and quality of life. The above items were assessed first at baseline and again at discharge from PAC. Logistic regression was used to determine factors that were associated with PAC length of stay (LOS), 14-day hospital readmission, and 1-year mortality. Results: A total of 267 adults (mean age 67.2 ± 14.7 years) with completed data were analyzed. MRS, activities of daily living (ADLs), instrumental activities of daily living (IADLs), BBS, and MMSE all had improved between disease onset and PAC discharge. Higher baseline and greater improvement of physical and cognitive functions between initial and final PAC assessments were significantly associated with less readmission, and lower mortality. Furthermore, the improved ADLs, FOIS, MNA, FMA-motor, and MMSE scores were related to LOS during PAC. Using logistic regression, we found that functional improvements ≥5 items [adjusted odds ratio (aOR) = 0.16; 95% confidence interval (CI) = 0.05-0.45] and improved MMSE (aOR = 0.19; 95% CI = 0.05-0.68) were significantly associated with reduced post-PAC mortality or readmission. Whereas, functional improvements ≥7 items, improved FOIS, and MNA significantly prolonged LOS during PAC. Conclusion: Physical performance parameters of patients with acute stroke improved after PAC. PAC assessment with multiple parameters better predicted clinical outcomes. These parameters could provide information on rehabilitation therapy for acute stroke patients receiving PAC.

Sex difference in the prognostic role of body composition parameters in Taiwanese patients undergoing transcatheter aortic valve implantation.

BACKGROUND: Evidence on association between body composition and outcomes of transcatheter aortic valve implantation (TAVI) is limited for Asian patients. This study investigated the prognostic role of body composition parameters in Taiwanese patients undergoing TAVI. MATERIALS AND METHODS: Data of consecutive patients undergoing TAVI for severe aortic stenosis between May 1, 2010 and August 31, 2019 were prospectively collected in this observational study. The association between body composition parameters (body mass index [BMI], body surface area [BSA], lean body mass [LBM], and LBM index) and cumulative mortality was analyzed using Cox proportional hazard regression model. RESULTS: A total of 221 patients (mean age 81.4 years), including 125 (56.6%) males, were included with median follow-up duration of 23.8 months. In males, multivariate analysis revealed that higher BMI (P = 0.035), BMI ≥ 20 kg/m2 (P = 0.026), and higher LBM index (P = 0.023) significantly predicted lower overall all-cause cumulative mortality. In females, none of the body composition parameters was significantly associated with all-cause cumulative mortality. Paradoxical association between BMI and estimated all-cause cumulative mortality was only significant among male patients. CONCLUSION: In Taiwanese TAVI patients, the prognostic effects of BMI and LBM index on cumulative mortality were only observed in males, not in females. Sex differences must be considered when stratifying risk among patients undergoing TAVI.

Cost-utility analysis of direct ventricular assist device vs double bridges to heart transplantation in patients with refractory heart failure.

OBJECT: This study compared the cost-utility of direct ventricular assist device (VAD) vs double bridges, extracorporeal membrane oxygenation (ECMO) before VAD, to heart transplantation in patients with refractory heart failure. MATERIALS AND METHODS: From a health payer perspective, a Markov model was developed. The cycle length was 1 month, and the time horizon was a lifetime. Probabilities and direct cost data were calculated from a nationwide claim database. Utility inputs were adopted from published sources. The utility was expressed as quality-adjusted life years (QALYs). Both costs and utility were discounted by an annual rate of 3%. Deterministic and probabilistic sensitivity analyses were performed to test the stability of the model. RESULTS: The direct VAD group had less lifetime costs (USD 95 910 vs USD 129 516) but higher lifetime QALYs than the double bridges group (1.73 vs 0.89). The sensitivity analysis revealed that the direct VAD group consistently had lower cost and higher QALYs during all variations in model parameters. The probability that direct VAD was cost-effective exceeded 75% at any levels of willing-to-pay. CONCLUSION: From a health insurance payer perspective, direct VAD bridge to heart transplantation appeared to be more cost-effective than double bridges in patients with refractory heart failure.

One-year follow-up of relapse to risky behaviors and incidence of syphilis among patients enrolled in the HIV case management program.

A longitudinal prospective study was conducted at an AIDS designated hospital in Taiwan. The study aimed to determine the incidence of syphilis and to identify risk factors predicting new onset syphilis and relapse into risky behaviors among 117 patients enrolled in the HIV case management program for 1 year. Having a new episode of syphilis was defined as patients had a fourfold increase of serum rapid plasma reagin titers from baseline to 12-month follow-up. After enrollment, 17% relapsed in unprotected sexual intercourse. New onset syphilis was noted in ten (10.4%) participants, and all were men having sex with men. The incidence of syphilis was 5.8 per 100 person-years. Predictors of a new episode of syphilis were higher CD4 cell counts [hazard ratio (HR), 1.003; 95% confidence interval (CI), 1.00-1.006], and recreational drug use (HR, 18.89; 95% CI, 2.78-128.15). Regular screening for syphilis among patients retaining in HIV care remains necessary.
