Clinical data on treatment regimen and use of medication among patients with hemophilia B in Korea.

ABSTRACT:

Background

To investigate the clinical treatment status, such as treatment regimen, bleeding events, and drug dose, in patients with hemophilia B in South Korea.

Methods

In this retrospective chart review, data of patients with hemophilia B from eight university hospitals were collected. Demographic and clinical data, treatment data, such as regimen and number of injections, dose of factor IX concentrate, and bleeding data were reviewed. Descriptive analyses were performed with annual data for 2019, 2020, and 2021, as well as the three years consecutively.

Results

The medical records of 150 patients with hemophilia B between January 1, 2019, and December 31, 2021, were collected. Among these, 72 (48.0%) were severe, 47 (31.3%) were moderate, and 28 (18.7%) were mild. The results showed approximately two times more patients receiving prophylaxis as those receiving on-demand therapy, with 66.1% of patients receiving prophylaxis in 2019, 64.9% in 2020, and 72.1% in 2021. Annualized bleeding rates were 2.2% (± 3.1) in 2019, 1.8% (± 3.0) in 2020, and 1.8% (± 2.9) in 2021 among patients receiving prophylaxis. For the doses of factor IX concentrate, patients receiving prophylaxis received an average of 41.6 (± 11.9) IU/Kg/Injection in 2019, 45.7 (± 12.9) IU/Kg/Injection in 2020, and 60.1 (± 24.0) IU/Kg/Injection in 2021.

Conclusions

Clinically, prophylaxis is more prevalent than reported. Based on insights gained from current clinical evidence, it is expected that the unmet medical needs of patients can be identified, and physicians can evaluate the status of patients and actively manage hemophilia B using more effective treatment strategies.

Project description:BackgroundHigh medication burdens are common in patients with chronic obstructive pulmonary disease (COPD). This study aimed to explore the associations of medication regimen complexity index (MRCI) with medication adherence and clinical outcomes among patients with acute exacerbations of COPD (AECOPD) after hospital discharge.MethodsData were obtained from a nationwide cohort study of inpatients with AECOPD in China. MRCI scores were calculated using the medication list 30 days after discharge and separated into COPD-specific and non-COPD MRCI scores. Medication adherence was measured by the withdrawal rate of COPD or inhaled long-acting bronchodilators 6 months after discharge. Clinical outcomes included re-exacerbations and COPD-related readmissions during the 30-day to 6-month follow-up period. The associations of MRCI with medication withdrawal and clinical outcomes were evaluated using univariate and multivariate logistic regressions. Potential covariates included sociodemographic factors, year of COPD diagnosis, post-bronchodilator percentage predicted forced expiratory volume in 1 s, mMRC score, CAT score, and comorbidities.ResultsAmong the 2853 patients included, the median total MRCI score was 7 [interquartile range (IQR), 7-13]. A high MRCI score (>7) was presented in 1316 patients (46.1%). Of the MRCI score, 91% were COPD specific. The withdrawal rates of the COPD and inhaled long-acting bronchodilators were 24.2% and 24.4%, respectively. Re-exacerbation and COPD-related readmission rates were 10.2% and 7.5%, respectively. After adjusting for covariates, patients with high total MRCI scores were less likely to discontinue COPD drugs [odds ratio (OR), 0.62; 95% confidence interval (CI), 0.52-0.74] and inhaled long-acting bronchodilators (OR, 0.68; 95%CI, 0.57-0.81); conversely, these patients were more likely to experience re-exacerbation (OR, 1.64; 95% CI, 1.27-2.11) and readmission (OR, 1.57; 95% CI, 1.17-2.10).ConclusionMRCI scores were relatively low among post-hospitalized patients with AECOPD in China. Higher MRCI scores were positively associated with adherence to COPD or inhaled medications, and risk of re-exacerbation and readmission.RegistrationClinicalTrials.gov identifier: NCT02657525.
