RESUMO
OBJECTIVE: Poor adherence to oral chemotherapy adversely impacts clinical outcomes and escalates overall healthcare costs. Despite barriers to medication adherence, a significant gap remains in assessing adherence to oral chemotherapy among multiple myeloma (MM) patients with lower socioeconomic status. Hence, our study aims to evaluate immunomodulator adherence in MM patients at a county hospital, primarily serving underrepresented and indigent individuals with low socioeconomic status across the greater Houston area. METHODS: Inclusion criteria composed of patients diagnosed with MM, aged at least 18 years, and treated with lenalidomide or pomalidomide-two widely used immunomodulators-for a minimum of 2 months or having two or more records of dispensation between May 2019 and May 2021. Adherence was gauged using an adjusted version of the medication possession ratio (MPR). RESULTS: Sixty-two patients were enrolled, yielding a mean MPR value of 88% (SD, ± 18.9). Of these, 43 patients (69.3%) demonstrated adherence with an MPR of ≥ 0.90. A significant difference was found in treatment duration between the adherent (mean 8.8 months; SD, ± 7.2) and non-adherent (mean 13.4 months; SD, ± 7.9) groups (p = 0.027). Notably, race/ethnicity demonstrated a significant difference (p = 0.048), driven by disparities in African American and Hispanic representation across adherence levels. CONCLUSION: In summary, our findings highlight race and treatment duration to be predictors of immunomodulator adherence among MM patients with lower socioeconomic status. Further research is imperative to devise and test innovative interventions aimed at enhancing medication adherence, thereby contributing to improved survival and healthcare quality in this population.

PURPOSE: Due to the multifaceted chemotherapy workflow within the hospital, many patients often experience delays in receiving their treatment. This study aims to evaluate the causes for chemotherapy administration delays and implement new methods to reduce delays from order release to chemotherapy administration on an inpatient oncology unit at a community-focused academic medical center. METHODS: In this prospective quality improvement study, we developed a process map to track baseline time stamps and utilized performance improvement tools to identify causes for chemotherapy delays. Based on recognized areas for improvement, the Plan-Do-Study-Act (PDSA) model was used to implement one cycle of interventions. Chemotherapy orders were collected, and benchmark time stamps were documented from the electronic medical record. RESULTS: The primary outcome for the number of chemotherapy delays, based on compliance rate, was reduced from 63/100 (63.0%) to 48/100 (48.0%), a 15% reduction (p = 0.046). Our primary outcome of chemotherapy delays, based on our institutional benchmark of <3 hours, did not show statistical significance. Median time from chemotherapy order release to administration decreased from 7.08 hours at baseline to 6.10 hours post-intervention, a 13.8% reduction (p < 0.0001). Median verification, preparation, and delivery times were all reduced post-intervention by 13.0% (p < 0.0001), 3.9% (p = 0.024), and 14.8% (p < 0.0001) respectively. CONCLUSIONS: This study allowed our institution to evaluate our current practice and reformulate the chemotherapy administration process. With the continuing education on the chemotherapy administration process and additional PDSA cycle interventions, it will help standardize our process and ultimately continue to reduce chemotherapy delays.

BACKGROUND: Adherence to oral endocrine therapy (OET) is crucial in ensuring its maximum benefit in the prevention and treatment of hormone receptor-positive (HR +) breast cancer (BC). Medication use behavior is suboptimal especially in racial/ethnic minorities with lower socioeconomic status (SES). AIM: We aimed to assess the impact of the coronavirus disease 2019 (COVID-19) pandemic on OET adherence and identify demographic and/or clinical characteristics associated with nonadherence in racial/ethnic minorities with lower SES. METHOD: A retrospective study was conducted at the Harris Health System in Houston, Texas. Data were collected during the 6 months before and 6 months after the start of the pandemic. The adherence was assessed using the prescription refill data using the proportion of days covered. A multivariable logistic regression model was used to identify demographic/clinical characteristics associated with nonadherence. Eighteen years or older patients on appropriate doses of OET for prevention or treatment of BC were included. RESULTS: In 258 patients, adherence was significantly lower during the pandemic (44%) compared to before the pandemic (57%). The demographic/clinical characteristics associated with OET nonadherence before the pandemic were Black/African American, obesity/extreme obesity, prevention setting, tamoxifen therapy, and 4 or more years on OET. During the pandemic, prevention setting and those not using home delivery were more likely to be nonadherent. CONCLUSION: OET adherence was significantly reduced during the COVID-19 pandemic in racial/ethnic minority patients with low SES. Patient-centered interventions are necessary to improve OET adherence in these patients.

Background Adherence to oral endocrine therapy (OET) is crucial in ensuring its maximum benefit in prevention and treatment of hormone receptor-positive (HR+) breast cancer (BC) in patients. Medication use behavior is suboptimal especially in racial/ethnic minorities of lower socioeconomic status (SES). We aimed to assess the OET adherence and its predictors in racial/ethnic minority patients of lower SES. Aim We aimed to assess the OET adherence and determine the predictors of OET nonadherence in racial/ethnic minority patients of lower SES. Method A retrospective study was conducted at the Harris Health System in Houston, Texas. Since the study period included the COVID-19 pandemic, data was collected during the 6 months prior and 6 months after the start of the pandemic. The adherence was assessed using the prescription refill data using the proportion of days covered. Multivariable logistic regression model was used to identify predictors of nonadherence. Eighteen years or older patients on appropriate doses of OET for prevention or treatment of BC were included. Result In 258 patients, the adherence was significantly lower during the pandemic (44%) compared to before the pandemic (57%). The predictors of OET nonadherence before the pandemic were Black/African American, obesity/extreme obesity, prevention setting, tamoxifen therapy, and 4 or more years on OET. During the pandemic, prevention setting and those not using home delivery were more likely to be nonadherent. Conclusion Racial/ethnic minority patients of lower SES, especially African Americans and those using OET for prevention of BC, require individualized interventions to improve adherence.
RESUMO
BACKGROUND: Major advances in the treatment of acute lymphoblastic leukemia (ALL) over the past decade have resulted in 5-year overall survival (OS) rates of 80% in mature B cell ALL, 50% in precursor B cell ALL, 50% to 60% in T cell ALL, and 60% to 70% in Philadelphia chromosome-positive (Ph+) ALL, as reported in studies from large, specialized centers. However, many patients treated in the community have limited access to novel therapies and stem cell transplantation (HSCT). PATIENTS AND METHODS: The purpose of this retrospective cohort analysis was to evaluate the clinical outcomes of patients ≥ 16 years with newly diagnosed ALL treated from October 2007 to June 2019 in the Harris County Health System, Houston, TX. RESULTS: One hundred forty-six patients were included, with newly diagnosed pre-B-ALL (n = 127), T-ALL (n = 18), and chronic myeloid leukemia and/or lymphoid blast crisis (n = 1). Median age was 35 years (16-82) at diagnosis, and 81(55%) were male. The majority of patients with pre-B ALL identified as Hispanic (n = 118, or 92%). Ninety-eight (67%) of patients were uninsured or indigent, receiving care under the county's financial assistance programs. Hyper-CVAD-based induction chemotherapy was administered in 134 (92%) of patients, while 9 (6%) were treated on different protocols, and 3 (2%) were not treated due to early death, or patient refusal. Imatinib was the most common TKI used in 17 of 30 or 57% of patients with Ph+ disease. Out of 137 evaluable for response patients, 117 (85%) achieved complete remission (CR + CRi), 19 (14%) had refractory disease, and 1 (1%) died within 4 weeks of diagnosis. Median follow-up time was 50 months (1.5-135). For the entire study cohort, the median duration of CR/CRi was 15.4 months. Out of 62 patients who were eligible for consolidative HSCT at first CR, 52 (89%) did not receive it, with lack of insurance being the most common reason (n = 29, or 56%). Barriers to utilization of novel therapies such as blinatumomab or CAR-T were also observed. Patient-caused delays in administration of chemotherapy and treatment interruptions of at least 30 days were seen in 31(23%) patients. At 1, 2, and 5 years, relapse rates were 37%, 56%, and 70%. Recurrent and/or refractory disease was the cause of death in most patients (n = 69 [85%]). Five-year EFS and OS rates were 22% and 38% for patients with pre-B ALL, 24% and 44% for patients with T ALL, and 13% and 27% for patients with Ph+ ALL. Median OS was significantly increased (not reached [NR] vs. 24 months; P = .00088) in patients with an indication for HSCT in first CR due to high-risk features who underwent HSCT, versus those who did not. CONCLUSION: Addressing barriers raised by socioeconomic disparities, increasing access to effective therapies, and including patients with ALL treated in the community in clinical trials may improve survival for underserved populations.
