PURPOSE Oral anticancer drugs (OACDs) have become increasingly prevalent over the past decade. OACD prescriptions require coordination between payers and providers, which can delay drug receipt. We examined the association between insurance type, pursuit of copayment assistance, pursuit of prior authorization (PA), and time to receipt (TTR) for new OACD prescriptions. METHODS We prospectively collected data on new OACD prescriptions for adult oncology patients from January 1, 2018, to December 31, 2019, including demographic and clinical characteristics, insurance type, and pursuit of PA and copayment assistance. TTR was defined as the number of days from prescription to OACD receipt. We summarized TTR using cumulative incidence and compared TTR by insurance type, pursuit of copayment assistance, and PA activity using the logrank test. RESULTS Our cohort of 1,024 patients was 53% male, and 40% were younger than 65. Twenty-six percent had commercial insurance only, 16% had Medicaid only, and 59% had Medicare with or without additional insurance. Eighty-six percent of prescriptions were successfully received. Across all prescriptions, 69% involved PA activity, and 21% involved the copayment assistance process. In unadjusted analyses, prescriptions involving the copayment assistance process had longer TTR compared with those not involving assistance (log-rank P value = .005) and OACDs covered by Medicare/commercial insurance had a longer TTR compared with Medicaid (log-rank P value = .006). The PA process was not associated with TTR (log-rank P value = .124). CONCLUSION The process for obtaining OACDs is complex. The copayment assistance process and Medicare/commercial insurance are associated with delayed TTR. New policies are needed to reduce time to OACD receipt. [ABSTRACT FROM AUTHOR]

PURPOSE Oral anticancer drug (OACD) prescriptions require extensive coordination between providers and payers, which can delay drug receipt. Specialty pharmacies facilitate communication between multiple entities. In 2018, our cancer center partnered with a freestanding organization to implement a hospital-based specialty pharmacy (HB-SP). We evaluated the time to drug receipt (TTR) before and after HB-SP implementation. METHODS Data were prospectively collected on all new OACD prescriptions for adult oncology patients from January 1, 2018, to December 31, 2019. In fall 2018, a HB-SP was initiated. We collected patient sociodemographic, clinical, and prescription data. TTR was the number of days from OACD prescription to drug receipt. We used multivariable logistic regression to examine factors associated with TTR ≤ 7 days before and after HB-SP implementation. RESULTS In total, 954 patients were included, representing 1,102 new OACDs. The majority of prescribed drugs were targeted OACDs (56%, n = 617), and 71% (n = 779) required prior authorization. Of all prescriptions, 84% (n = 960) were successfully received with an overall median TTR of 7 days. In unadjusted analysis, HB-SP implementation, drug class, race and ethnicity, and prior authorization requirement were significantly associated with TTR. Adjusted analyses found that patients were more likely to receive their drugs ≤ 7 days after HB-SP implementation (53% v 47%; adjusted odds ratio [aOR], 1.29; 95% CI, 1.00 to 1.68; P = .05). CONCLUSION The implementation of a HB-SP in partnership with a collaborative care model contributed to a decrease in TTR for OACDs. This difference is in part attributable to improved care coordination and communication. A centralized approach may improve overall efficiency due to fewer practice disruptions.

Background Sedative-hypnotic medications are used to treat chemotherapy-related nausea, anxiety, and insomnia. However, prolonged sedative-hypnotic use can lead to dependence, misuse, and increased health-care use. We aimed to estimate the rates at which patients who receive adjuvant chemotherapy for breast cancer become new persistent users of sedative-hypnotic medications, specifically benzodiazepines and nonbenzodiazepine sedative-hypnotics (Z-drugs). Methods Using the MarketScan health-care claims database, we identified sedative-hypnotic–naïve patients who received adjuvant chemotherapy for breast cancer. Patients who filled 1 and more prescriptions during chemotherapy and 2 and more prescriptions up to 1 year after chemotherapy were classified as new persistent users. Univariate and multivariable logistic regression analyses were used to estimate odds of new persistent use and associated characteristics. Results We identified 22 039 benzodiazepine-naïve patients and 23 816 Z-drug–naïve patients who received adjuvant chemotherapy from 2008 to 2017. Among benzodiazepine-naïve patients, 6159 (27.9%) filled 1 and more benzodiazepine prescriptions during chemotherapy, and 963 of those (15.6%) went on to become new persistent users. Among Z-drug–naïve patients, 1769 (7.4%) filled 1 and more prescriptions during chemotherapy, and 483 (27.3%) became new persistent users. In both groups, shorter durations of chemotherapy and receipt of opioid prescriptions were associated with new persistent use. Medicaid insurance was associated with new persistent benzodiazepine use (odds ratio = 1.88, 95% confidence interval = 1.43 to 2.47) compared with commercial or Medicare insurance. Conclusions Patients who receive sedative-hypnotic medications during adjuvant chemotherapy for breast cancer are at risk of becoming new persistent users of these medications after chemotherapy. Providers should ensure appropriate sedative-hypnotic use through tapering dosages and encouraging nonpharmacologic strategies when appropriate. [ABSTRACT FROM AUTHOR]

Background: Opioid misuse is a public health crisis, and unused postoperative opioids are an important source. Although 70% of pills prescribed go unused, only 9% are discarded. This study evaluated whether an inexpensive pill-dispensing device with mail return capacity could enhance disposal of unused opioids after cancer surgery.Methods: A prospective pilot study was conducted among adult patients who underwent major cancer-related surgery. Patients received opioid prescriptions in a mechanical device (Addinex) linked to a smartphone application (app). The app provided passwords on a prescriber-defined schedule. Patients could enter a password into the device and receive a pill if the prescribed time had elapsed. Patients were instructed to return the device and any unused pills in a disposal mailer. The primary end point was feasibility of device return, defined as ≥50% of patients returning the device within 6 weeks of surgery. Also explored was total pill use and return as well as patient satisfaction.Results: Among 30 patients enrolled, the majority (n = 24, 80%) returned the device, and 17 (57%) returned it within 6 weeks of surgery. In total, 567 opioid pills were prescribed and 170 (30%) were used. Of 397 excess pills, 332 (84% of unused pills, 59% of all pills prescribed) were disposed of by mail. Among 19 patients who obtained opioids from the device, most (n = 14, 74%) felt the benefits of the device justified the added steps involved.Conclusions: Use of an inexpensive pill-dispensing device with mail return capacity is a feasible strategy to enhance disposal of unused postoperative opioids.

Background: Adolescents and young adults (AYA) with sarcoma experience both acute and chronic pain related to their disease and treatment. Studies in older adults have reported a high risk of persistent opioid use after cancer therapy among previously opioid‐naive patients; however, few studies have evaluated posttreatment opioid use among AYAs. This article describes patterns of new persistent opioid use among AYAs in the year after treatment for sarcoma. Methods: Opioid‐naive patients who were 10 to 26 years old and diagnosed with sarcoma (2008‐2016) were identified with the IBM Marketscan Database. Included subjects had an International Classification of Diseases code for sarcoma (ninth or tenth revision), received anticancer therapy (chemotherapy, surgery, and/or radiation) within 30 days of the first diagnosis code, and had continuous insurance coverage (commercial or Medicaid) for more than 12 months both before the diagnosis and after the last therapy. The primary outcome was new persistent opioid use, which was defined as at least 2 opioid prescriptions in the 12 months following treatment completion. Covariates included age, sex, insurance, tumor type, surgical procedure, mental health (MH) or substance use diagnoses before or during therapy, and concomitant lorazepam use. Results: In total, 938 patients met the inclusion criteria; 521 (56%) were male, and 578 (62%) were younger than 18 years. In total, 727 (78%) had commercial insurance, and 273 (29%) had an MH diagnosis either before or during the treatment period. Of the total group, 464 (49%) used opioids during treatment only. Of those who used opioids during treatment, 135 (23%) received at least 2 prescriptions in the year after therapy. In a multivariable analysis, Medicaid versus commercial insurance (odds ratio [OR], 1.74; 95% confidence interval [CI], 1.15‐2.64) and non–soft tissue sarcoma (OR for Ewing sarcoma, 3.23; 95% CI, 1.81‐5.78; OR for osteosarcoma, 2.05; 95% CI, 1.36‐3.09) conferred a higher likelihood of new persistent use. Conclusions: In this cohort of AYAs treated for sarcoma, 64% of the patients received opioid prescriptions during treatment, and 23% of these patients became new persistent users. Because of the risks associated with persistent opioid use, studies of novel pain management strategies along with age‐appropriate education and anticipatory guidance are urgently needed. Lay Summary: Using an insurance claims database, we conducted a study to determine the rate of new persistent opioid use among adolescents and young adults treated for sarcoma.We found that 64% of adolescents and young adults treated for sarcoma received opioid prescriptions during treatment, and 23% of these patients met the criteria for new persistent opioid use.These findings support the need for age‐appropriate education and novel pain management strategies in this vulnerable population. In this cohort of adolescents and young adults treated for sarcoma, 64% of the patients received opioid prescriptions during treatment, and 23% of these patients became new persistent users. Because of the risks associated with persistent opioid use, studies of novel pain management strategies along with age‐appropriate education and anticipatory guidance are urgently needed.

PURPOSE: COVID-19 has altered healthcare delivery. Previous work has focused on patients with cancer and COVID-19, but little has been reported on healthcare system changes among patients without COVID-19. METHODS: We performed a retrospective study of patients with breast cancer (BC) in New York City between February 1, 2020, and April 30, 2020. New patients were included as were patients scheduled to receive intravenous or injectable therapy. Patients with COVID-19 were excluded. Demographic and treatment information were obtained by chart review. Delays and/or changes in systemic therapy, surgery, radiation, and radiology related to the pandemic were tracked, along with the reasons for delay and/or change. Univariate and multivariable analysis were used to identify factors associated with delay and/or change. RESULTS: We identified 350 eligible patients, of whom 149 (42.6%) experienced a delay and/or change, and practice reduction (51.0%) was the most common reason. The patients who identified as Black or African American, Asian, or Other races were more likely to experience a delay and/or change compared with White patients (Black, 44.4%; Asian, 47.1%; Other, 55.6%; White, 31.4%; P = .001). In multivariable analysis, Medicaid compared with commercial insurance (odds ratio [OR], 3.04; 95% CI, 1.32 to 7.27) was associated with increased odds of a delay and/or change, whereas stage II or III BC compared with stage I (OR, 0.38; 95% CI, 0.15 to 0.95; and OR, 0.28; 95% CI, 0.08 to 0.092, respectively) was associated with decreased odds of a delay and/or change. CONCLUSION: Almost half of the patients with BC without COVID-19 had a delay and/or change. We found racial and socioeconomic disparities in the likelihood of a delay and/or change. Further studies are needed to determine the impact these care alterations have on BC outcomes. [ABSTRACT FROM AUTHOR]

Background: Cardiovascular disease (CVD) is the leading cause of death among patients with early-stage breast cancer (BC), but adherence to cardiovascular disease risk factor (CVD-RF) medications is reported to be poor in BC survivors. The objective of the current study was to determine the association between nonadherence to CVD-RF medications and cardiovascular events in BC survivors.Methods: The authors included patients with stages I to III BC from the Surveillance, Epidemiology, and End Results (SEER)-Medicare database who had Medicare part D coverage and who were taking at least 1 CVD-RF medication prior to their BC diagnosis (2008-2013). Logistic regression was performed to define factors associated with nonadherence. Cox regression was used to calculate the association between nonadherence and new cardiac events after treatment.Results: Among 15,576 patients included in the current analysis, 4797 (30.8%) were nonadherent to at least 1 category after the initial BC treatment period. Black race, greater comorbidity burden, more advanced cancer stage, hormone receptor-negative status, and receipt of chemotherapy were found to be associated with nonadherence. Nonadherence after treatment demonstrated a trend toward an increased risk of a subsequent cardiac event (hazard ratio [HR], 1.15; 95% CI 1.00-1.33 [P = .06]). This effect size increased with nonadherence to a greater number of medications (P < .01). There was an increased risk of experiencing a cardiac event noted with becoming nonadherent to hypertension medications (HR, 1.33; 95% CI, 1.18-1.51 [P < .0001]), hyperlipidemia medications (HR, 1.21; 95% CI, 1.05-1.40 [P = .009]), and diabetes medications (HR, 1.31; 95% CI, 1.10-1.56 [P = .003]).Conclusions: Nonadherence to CVD-RF medications after treatment of BC is associated with an increased risk of a cardiac event. Improving outcomes and reducing morbidity after a diagnosis of BC requires attention to non-BC conditions. [ABSTRACT FROM AUTHOR]

Purpose: Multidisciplinary care (MDC) encourages multiple specialists to formulate a unified treatment plan. We sought to determine the frequency and predictors of MDC and assess the association between MDC and nationally-recognized quality metrics in patients with breast cancer. Methods: We used the surveillance, epidemiology, and end results-medicare dataset to evaluate patients diagnosed with stages I-III breast cancer who underwent breast-conserving surgery between 2002 and 2011 with follow-up to 2012. We defined MDC as a visit claim from a surgeon, radiation oncologist and medical oncologist within 12 months of diagnosis. We used multivariable regression analysis to determine the association between demographic and clinical variables and MDC, and to assess the association between MDC and three nationally-recognized quality indicators (adjuvant hormone therapy for hormone receptor-positive tumors, chemotherapy for hormone receptor-negative cancer, and radiation after lumpectomy). Results: Of the 61,039 patients in our initial cohort, 53,849 (88.2%) saw a medical oncologist, 46,521 (76.2%) saw a radiation oncologist, and 43,280 (70.9%) were evaluated by all three providers the first year after diagnosis. MDC use was higher in patients with the highest socioeconomic status compared with the lowest [odds ratio (OR) 1.74, 95% CI 1.63-1.86], in patients diagnosed in later years, and those with stage III disease compared to stage I [OR 1.29, 95% CI 1.19-1.41]. Patients older in age (≥80 vs. 65-69 years, OR 0.33, 95% CI 0.31-0.34), patients with more comorbidities, those who lived in a rural setting compared to urban (OR 0.61, 95% CI 0.57-0.64), and unmarried patients (OR 0.79, 95% CI 0.76-0.82) were less likely to see all three providers. In a multivariable analysis, MDC use was associated with increased likelihood of meeting each quality metric. Conclusion: Early stage breast cancer patients were evaluated by a surgeon, radiation oncologist and medical oncologist less than 75% of the time. Enhanced coordination of care and navigation programs may improve the quality of care delivered. [ABSTRACT FROM AUTHOR]

Reducing delays related to inpatient chemotherapy may reduce healthcare costs. Using a national database, we identified patients with lymphoma/leukemia with ≥1 etoposide, vincristine, doxorubicin, cyclophosphamide, and prednisone (EPOCH) chemotherapy claim and evaluated chemotherapy initiation delay (ID), >1 day from admission. Standard tests/procedures prior to initiation were evaluated. Among 4453 inpatient cycles, 19.7% had ID, odds ratio 2.28 (95% confidence interval: 1.83–2.85) with cycle 1 compared to cycle 2, and mean costs were higher in patients with ID than without ID (p< .0001). Prior to cycle 1, patients were more likely to undergo routine diagnostic procedures compared to subsequent cycles. Efforts to perform routine procedures prior to admission may reduce hospital length of stay and costs. [ABSTRACT FROM PUBLISHER]

Image-guided percutaneous liver biopsy (PLB) is a diagnostic tool for lesions in the liver. Hemorrhage is the most common complication. We selected patients with a diagnostic claim for cancer who had undergone PLB. There were a total of 26,941 patients who underwent PLB. Hemorrhage risk was 1.43% among patients undergoing PLB. When stratified by setting, odds of hemorrhage were 4.5 times higher when biopsy was performed in an inpatient setting (p < .001). Risk factors associated with hemorrhage included marital status, liver cancer and comorbidity score. The use of PLB has increased over time. Reassuringly, the hemorrhage risk associated with PLB is low. [ABSTRACT FROM AUTHOR]

Purpose There is substantial variability in the frequency of serum tumor marker testing in patients with advanced solid tumors. We performed a retrospective analysis to evaluate the frequency of serum tumor marker use. Methods Patients with a diagnosis of advanced cancer with outpatient visits between July 1, 2013, and June 30,2014, at a single center were included. Tumor and stage were determined by International Classification of Diseases, Ninth Revision codes and confirmed with tumor registry and medical record review. For each patient, we recorded the dates of each of the following tumor markers: α-fetoprotein, CA-125, CA 15-3, CA 19-9, CA 27-29, and carcinoembryonic antigen. We evaluated the number of tests per patient over 12 months and the maximum number of tests per patient per month. Results We included 928 patients in the analysis. The mean number of any individual test per patient was seven tests, and the maximum number was 35 tests; the mean number of total tests per patient was 12 tests, and the maximum number was 70 tests; 16.3% of patients had more than 12 individual tests per year. In a 1-month span, 34.3% of patients had more than one individual test. CA 19-9 and carcinoembryonic antigen were the most commonly overused tests. Conclusion We found a high rate of serum tumor marker testing use in patients with advanced solid tumors. Given the increasing costs of cancer care, efforts should be made to determine the benefit of serum tumor markers in the follow-up care of patients with advanced solid tumors. [ABSTRACT FROM AUTHOR]

Purpose: Image-guided transthoracic needle biopsy (IGTTNB) is an important tool in the diagnosis of patients with cancer. Common complications include pneumothorax and chest tube placement, with rates ranging from 6% to 57%. We performed a population-based study to determine patterns of use, complications, and costs associated with IGTTNB. Methods: The Premier Perspective database was used to identify patients with cancer with > one claim for IGTTNB from 2006 to 2012. Patients were stratified on the basis of inpatient versus outpatient setting. Pneumothorax was defined by a new claim within 1 month of IGTTNB; hospitalization and chest tube placement rates were analyzed. Multivariable analysis was used to identify factors associated with pneumothorax. Results: We Identified 79,518 patients with cancer who underwent IGTTNB: 42,955 (54.0%) outpatients and 36,563 (46.0%) inpatients. Of patients who underwent outpatient IGTTNB, 5,261 (12.2%) developed a pneumothorax. Of those, 1,006 (19.1%, 2.3% of total) were hospitalized, and 180 (3.4%, 0.42% of total) required chest tubes. Pneumothorax after outpatient IGTTNB was associated with number of comorbidities, rural site, hospital bed size of more than 600, and biopsy of parenchymal as opposed to pleural lesions. Of patients who underwent inpatient IGTTNB, 7,830 (21.4%) developed a pneumothorax, and 2,894 (36.0%, 7.9% of total) required chest tube. Over time, total IGTTNB volume increased by 40.6%, and mean outpatient cost per procedure increased by 24.4%. Conclusion: While pneumothorax was frequent in outpatients, rates of hospitalization and chest tube placement were low. As screening for lung cancer increases, we anticipate an increased need for IGTNBB. Patients can be reassured by the low rate of serious complications. [ABSTRACT FROM AUTHOR]

Background: The scope of medical student knowledge may differ by the student's future intended specialty. Aim: To determine whether medical student knowledge of and confidence with anticoagulation differed by perceived likelihood of managing anticoagulation in future practice. Methods: One hundred and twenty-three third- and fourth-year medical students (41% response rate) participated in a cross-sectional web-based survey. We assessed whether perceived likelihood of managing anticoagulation in future intended practice was associated with anticoagulation knowledge and confidence with managing anticoagulation. Results: Out of 24 questions assessing anticoagulation knowledge, the mean percentage correct was 58% (SD 29%). Anticoagulation knowledge did not differ by perceived likelihood of managing anticoagulation as part of their future practice. However, students predicting higher likelihood of managing anticoagulation in their future practice were significantly more confident about their abilities to manage anticoagulation ( p = 0.005). Conclusion: Using anticoagulation as a model, we did not find evidence that medical student knowledge differed by perceived scope of future practice. Future study will need to confirm whether range and depth of medical knowledge differs by medical students’ intended future practice and specialties. [ABSTRACT FROM AUTHOR]

A response by Melissa K. Accordino and colleagues to a letter to the editor about their article "Serum tumor marker use in patients with advanced solid tumors," published in a previous issue is presented.

Background: For patients with stages I-III colon cancer who have undergone surgical resection, guidelines recommend surveillance colonoscopy at 1 year. However, limited data exist on adherence and associated factors. We aimed to determine the rate of adherence to surveillance colonoscopy at 1 year among nonmetastatic colon cancer patients who underwent resection and factors associated with adherence. Methods: In this population-based retrospective cohort study, the Surveillance, Epidemiology, and End Results (SEER)–Medicare database was used. We identified patients with stages I-III colon cancer who underwent surgical resection and survived >3 years without recurrence (no chemotherapy after 8 months) from 2002–2011. Our primary outcome was a colonoscopy claim 10–15 months after resection. We used multivariable regression analysis to assess associations between sociodemographic and clinical factors and receipt of timely colonoscopy. Results: Among 28,732 patients who survived >3 years without recurrence, 7967 (28%) did not undergo colonoscopy; 12,033 (42%) had it at one year, with 3159 (11%) before 10 months and 5573 (19%) after 15 months. Decreased adherence was associated with older age; being male versus female; being black or Hispanic versus white; higher tumor stage; left-sided tumors versus right sided; and increased comorbidities. Chemotherapy receipt was associated with increased adherence (odds ratio 2.06; 95% confidence interval 1.88–2.24). Conclusions: In a large population-based sample of individuals aged ⩾ 65 years, only 42% of colon cancer survivors underwent 1-year surveillance colonoscopy. Demographic and clinical factors were associated with adherence. [ABSTRACT FROM AUTHOR]

PURPOSE: Follow-up guidelines vary widely among national organizations for patients with early-stage breast cancer treated with curative intent. We sought to evaluate the patterns and predictors of provider follow-up care within the first 5 years after diagnosis. METHODS: Using the SEER-Medicare linked data set, we evaluated patients who were diagnosed with stage I and II breast cancer who underwent breast-conserving surgery from 2002 to 2007 with follow-up until 2012. We defined discontinuation of follow-up as > 12 months from the previous physician visit without a visit claim from either a surgeon, medical oncologist, or radiation oncologist. We performed a multivariable logistic regression and Cox proportional hazards regression analysis to determine factors associated with the discontinuation of follow-up care. RESULTS: Of the 30,053 patients enrolled in our initial cohort, 25,781 (85.8%) saw a medical oncologist and 21,612 (71.9%) saw a radiation oncologist in the first year in addition to a surgeon. Over the 5 years, 6,302 patients (21.0%) discontinued follow-up visits. Discontinuation of physician visits increased with increasing age. Women with stage II cancer (v stage I) were less likely to discontinue follow-up visits (odds ratio, 0.78; 95% CI, 0.73 to 0.83). Time to early discontinuation was greater for patients with hormone receptor–negative tumors (hazard ratio, 1.14; 95% CI, 1.05 to 1.24). Women who were diagnosed more recently were less likely to discontinue seeing any physician. CONCLUSION: Twenty-one percent of patients with early-stage breast cancer discontinued seeing any oncology provider over the 5 years after diagnosis. Coordination of follow-up care between oncology specialists may reduce discontinuation rates and increase clinical efficiency. [ABSTRACT FROM AUTHOR]

Question: What are the benefits and risks of lung cancer screening with low-dose computed tomography (LDCT) in patients at increased risk for lung cancer due to smoking and age? Review scope: Included studies evaluated LDCT screening for lung cancer and reported =" src="ge9.gif"/> 1 of the following outcomes: lung cancer−specific or all-cause mortality, nodule detection rate, frequency of additional imaging, frequency of invasive diagnostic procedures (e.g., needle or bronchoscopic biopsy, surgical biopsy, or surgical resection), complications from evaluation of suspected lung cancer, or rate of smoking cessation or reinitiation. Exclusion criteria were studies with risk factors other than smoking, and meta-analyses or case reports of patients diagnosed with lung cancer. Review methods: MEDLINE, EMBASE/Excerpta Medica, and Cochrane Library (all to Apr 2012); and reference lists of related articles and reviews were searched for published, English-language, randomized, controlled trials (RCTs) or cohort studies. 8 RCTs (n = 83 331, lower age range 47 to 60 y, upper age range 69 to 80 y; 55% to 100% men; =" src="ge9.gif"/> 15 to =" src="ge9.gif"/> 30 pack-y of smoking; < 10 to  15 y since smoking cessation) and 13 cohort studies met inclusion criteria. Only the results of RCTs are reported in this abstract. 5 RCTs compared LDCT with no screening and 3 with chest radiography. 4 RCTs reported preliminary data only. 3 RCTs reported mortality. Data were not pooled. Main results: CT screening reduced risk for all-cause and lung cancer mortality more than chest radiography in the largest trial; CT screening and usual care did not differ in 2 trials (Table). Average nodule detection rate across 8 RCTs was 20% (range 3% to 30%); in 6 RCTs, including all 3 comparing LDCT with chest radiography, > 90% of nodules were benign. Conclusion: In patients at increased risk for lung cancer, low-dose computed tomography screening for lung cancer detection reduced lung cancer–specific and all-cause mortality more than chest radiography in 1 large trial but showed no effect compared with usual care in 2 smaller trials.

The article presents information on the review of the research on the low-dose computed tomography (LDCT) with respect to the benefits and risk of the lung cancer screening applications. It mentions the Medline, Cochrane Library, and EMBASE/Excerpta Medica for the methodology involved, and highlights the analysis results including the reduction of lung cancer mortality in comparison to the chest radiography.

Purpose: Medication nonadherence is common among patients with breast cancer (BC) and increases BC mortality and complications from comorbidities. There is growing interest in mobile health interventions such as smartphone applications (apps) to promote adherence., Methods: Use of Medisafe, a medication reminder and tracking app, was tested over 12 weeks among patients on BC treatment and at least one oral medication. Study participants were instructed to generate adherence reports every 4 weeks through Medisafe and were deemed to have completed the intervention if >50% of reports were generated. The primary end point was feasibility of the intervention, defined as a completion rate of ≥75% of consented patients. Secondary end points included changes in self-reported nonadherence from baseline to 12 weeks and patient-reported outcomes including reasons for nonadherence and satisfaction with Medisafe. We conducted univariable and multivariable analyses to evaluate demographic and clinical factors associated with intervention completion., Results: Among 100 patients enrolled, 78 (78.0%) completed the intervention. Age, race, ethnicity, clinical stage, and type of medication were not associated with odds of intervention completion. Self-reported nonadherence rates did not improve from baseline to postintervention in the overall study population. However, among patients with self-reported nonadherence at baseline, 26.3% reported adherence postintervention; these patients frequently reported logistical barriers to adherence. Study participants reported high levels of satisfaction with Medisafe, noting that the app was highly functional and provided high-quality information., Conclusion: Smartphone apps such as Medisafe are feasible and associated with high patient satisfaction. They may improve adherence in nonadherent patients and those who face logistical challenges interfering with medication-taking. Future trials of mobile health interventions should target patients at high risk for medication nonadherence.
