ABSTRACT

OBJECTIVE To systematically review the pharmacoeconomic evaluation literature about proprotein convertase subtilisin/kexin type 9 (PCSK9) inhibitors for the prevention of cardiovascular disease in patients with hypercholesterolemia, and to provide a reference for clinical treatment, health decision-making and future follow-up research. METHODS Retrieved from English and Chinese databases such as PubMed and CNKI, the pharmacoeconomic literature about PCSK9 inhibitors (evolocumab and alirocumab) for the prevention of cardiovascular disease in patients with hypercholesterolemia was collected from the establishment of the database to October 8, 2023. The quality of the included literature was assessed with Consolidated Health Economic Evaluation Reporting Standards 2022 (CHEERS 2022) scale. The descriptive analysis was performed for basic information, model structure, related parameters, sensitivity analysis and the results of included studies. RESULTS & CONCLUSIONS A total of 29 literature were included, with overall good quality. The evaluation mainly adopted the Markov model from the healthcare system, payer and societal perspective. The effectiveness and utility data mainly came from the previous studies; the direct cost was mainly considered with a discount rate of 1.5%-5.0% per year, while the willingness-to-pay threshold was often set at 1-3 times the gross domestic product per capita. Most health output indicators were measured in life years and quality-adjusted life years. The sensitivity analysis of most studies demonstrated the robustness and the main influential factor was the drug cost. Most Chinese studies showed that PCSK9 inhibitor was not cost-effective for the prevention of cardiovascular disease in patients with acute coronary syndrome, myocardial infarction and atherosclerotic cardiovascular disease. It was cost-effective to use PCSK9 inhibitors for the prevention of cardiovascular disease only in specific groups, such as patients with triple vessel disease, patients with newly diagnosed acute coronary syndrome and low-density lipoprotein cholesterol≥100 mg/dL. Future research should refer to the CHEERS 2022 scale to improve the design, and strive to select large-scale, high-quality data to enhance the quality of reports and the transparency of health decisions, so as to more accurately assess the cost-effectiveness of PCSK9 inhibitors.

ABSTRACT

Objective To investigate the clinical value of transrectal ultrasound-guided improved 13-core prostate biopsy in the detection of prostate cancer.Methods Retrospective analysis was conducted in the clinical data of 82 clinically suspected prostate cancer patients in Shaanxi Provincial People's Hospital from October 2015 to October 2016.All patients were undergone transrectal uhrasound-guided improved 13-core prostate biopsy and surgical treatment,and the prostate biopsy results were compared with the postoperative pathological results.The accuracy of the improved 13-core prostate biopsy and the standard 6-core prostate biopsy was compared.The complications of improved 13-core prostate biopsy were also discussed.Results The diagnostic results of prostate biopsy included prostate cancer in 26 patients and benign prostatic hyperplasia (BPH) in 54 patients.The diagnostic results of 80 patients are consistent with postoperative pathological examination.Two patients were diagnosed as BPH by biopsy,but confirmed to be prostate cancer by postoperative pathological examination.The accuracy of the improved 13-core prostate biopsy and the standard 6-core prostate biopsy were 97.6% (80/82) and 84.1% (69/82) respectively,and the difference showed statistical significance (P =0.023).No severe complications were found in patients who underwent transrectal ultrasound improved 13-core prostate biopsy.Conclusion Transrectal ultrasound guided improved 13-core prostate biopsy can increase the detection rate significantly.It is safe and efficacious,and can be widely used in clinic.
