Substance abuse is a growing, but mostly silent, epidemic among older adults. We sought to analyze the trends in admissions for substance abuse treatment among older adults (aged 55 and older). Treatment Episode Data Set - Admissions (TEDS-A) for period between 2000 and 2012 was used. The trends in admission for primary substances, demographic attributes, characteristics of substance abused and type of admission were analyzed. While total number of substance abuse treatment admissions between 2000 and 2012 changed slightly, proportion attributable to older adults increased from 3.4% to 7.0%. Substantial changes in the demographic, substance use pattern, and treatment characteristics for the older adult admissions were noted. Majority of the admissions were for alcohol as the primary substance. However there was a decreasing trend in this proportion (77% to 64%). The proportion of admissions for following primary substances showed increase: cocaine/crack, marijuana/hashish, heroin, non-prescription methadone, and other opiates and synthetics. Also, admissions for older adults increased between 2000 and 2012 for African Americans (21% to 28%), females (20% to 24%), high school graduates (63% to 75%), homeless (15% to 19%), unemployed (77% to 84%), and those with psychiatric problems (17% to 32%).The proportion of admissions with prior history of substance abuse treatment increased from 39% to 46% and there was an increase in the admissions where more than one problem substance was reported. Ambulatory setting continued to be the most frequent treatment setting, and individual (including self-referral) was the most common referral source. The use of medication assisted therapy remained low over the years (7% - 9%). The changing demographic and substance use pattern of older adults implies that a wide array of psychological, social, and physiological needs will arise. Integrated, multidisciplinary and tailored policies for prevention and treatment are necessary to address the growing epidemic of substance abuse in older adults.

Recruitment and retention strategies for patient-centered outcomes research are evolving and research on the subject is limited. In this work, we present a conceptual model of patient-centered recruitment and retention, and describe the recruitment and retention activities and related challenges in a patient-centered comparative effectiveness trial. This is a multicenter, longitudinal randomized controlled trial in localized prostate cancer patients. We recruited 743 participants from three sites over 15 months period (January 2014 to March 2015), and followed them for 24 months. At site 1, of the 773 eligible participants, 551 (72%) were enrolled. At site 2, 34 participants were eligible and 23 (68%) enrolled. Of the 434 eligible participants at site 3, 169 (39%) enrolled. We observed that strategies related to the concepts of trust (e.g., physician involvement, ensuring protection of information), communication (e.g., brochures and pamphlets in physicians’ offices, continued contact during regular clinic visits and calling/emailing assessment), attitude (e.g., emphasizing the altruistic value of research, positive attitude of providers and research staff), and expectations (e.g., full disclosure of study requirements and time commitment, update letters) facilitated successful patient recruitment and retention. A stakeholders’ advisory board provided important input for the recruitment and retention activities. Active engagement, reminders at the offices, and personalized update letters helped retention during follow-up. Usefulness of telephone recruitment was site specific and, at one site, the time requirement for telephone recruitment was a challenge. We have presented multilevel strategies for successful recruitment and retention in a clinical trial using a patient-centered approach. Our strategies were flexible to accommodate site-level requirements. These strategies as well as the challenges can aid recruitment and retention efforts of future large-scale, patient-centered research studies. Clinicaltrials.gov , ID: NCT02032550 .

Stress is implicated in the pathogenesis and progression of HIV. The Transcendental Meditation (TM) is a behavioral stress reduction program that incorporates mind–body approach, and has demonstrated effectiveness in improving outcomes via stress reduction. We evaluated the feasibility of implementing TM and its effects on outcomes in persons with HIV. In this community-based single blinded Phase-I, randomized controlled trial, outcomes (psychological and physiological stress, immune activation, generic and HIV-specific health-related quality of life, depression and quality of well-being) were assessed at baseline and at six months, and were compared using parametric and nonparametric tests. Twenty-two persons with HIV were equally randomized to TM intervention or healthy eating (HE) education control group. Retention was 100% in TM group and 91% in HE control group. The TM group exhibited significant improvement in vitality. Significant between group differences were observed for generic and HIV-specific health-related quality of life. Small sample size may possibly limit the ability to observe significant differences in some outcomes. TM stress reduction intervention in community dwelling adults with HIV is viable and can enhance health-related quality of life. Further research with large sample and longer follow-up is needed to validate our results.

Data regarding the association between photodynamic therapy (PDT) and mortality in lung cancer patients are limited. We analyzed the association between PDT and mortality in patients with stage III or IV non-small cell lung cancer (NSCLC) using data from the National Cancer Database (NCDB) between 2004 and 2016. From the NCDB, we identified patients receiving laser ablation/cryosurgery or local tumor destruction/excision (which includes PDT). From Medicare and Medicaid claims between 2000 and 2013, we identified NSCLC patients receiving PDT and those receiving bronchoscopy, then used these to confirm the PDT treatment. From NCDB, we extracted NSCLC patients who received radiation with chemotherapy, radiation alone or chemotherapy alone. We used survival analysis to determine the association between PDT and mortality. Between 2004 and 2016, 457,556 NSCLC patients with stage III or stage IV were identified, of which 147 received PDT with radiation and chemotherapy, 227,629 received radiation with chemotherapy, 106,667 had radiation therapy alone and 122,193 received chemotherapy alone. Compared to the radiation alone group, the PDT group and radiation with chemotherapy group had lower hazard of mortality (50% and 53% lower, respectively). Among the NSCLC patients with stage III or stage IV disease, the addition of PDT to radiation therapy offers survival benefit over radiation therapy alone.

BACKGROUND: Substance use disorder in patients with cancer has implications for outcomes. The objective of this study was to analyze the effects of the type and timing of substance use on outcomes in elderly Medicare recipients with advanced prostate cancer.METHODS: This was an observational cohort study using Surveillance, Epidemiology, and End Results (SEER)‐Medicare linked data from 2000 to 2009. Among men who were diagnosed with advanced prostate cancer between 2001 and 2004, we identified those who had a claim for substance use disorder in the year before cancer diagnosis, 1 year after cancer diagnosis, and an additional 4 years after diagnosis. The outcomes investigated were use of health services, costs, and mortality.RESULTS: The prevalence of substance use disorder was 10.6%. The category drug psychoses and related had greater odds of inpatient hospitalizations (odds ratio [OR], 2.3; 95% confidence interval [CI], 1.9‐2.8), outpatient hospital visits (OR, 2.6; 95% CI, 1.9‐3.6), and emergency room visits (OR, 1.7; 95% CI, 1.2‐2.4). Substance use disorder in the follow‐up phase was associated with greater odds of inpatient hospitalizations (OR, 2.0; 95% CI, 1.8‐2.2), outpatient hospital visits (OR, 2.0; 95% CI, 1.7‐2.4), and emergency room visits (OR, 1.7; 95% CI, 1.5‐2.1). Compared with men who did not have substance use disorder, those in the category drug psychoses and related had 70% higher costs, and those who had substance use disorder during the follow‐up phase had 60% higher costs. The hazard of all‐cause mortality was highest for patients in the drug psychoses and related category (hazard ratio, 1.3; 95% CI, 1.1‐1.7) and the substance use disorder in treatment phase category (hazard ratio, 1.5; 95% CI, 1.3‐1.7).CONCLUSIONS: The intersection of advanced prostate cancer and substance use disorder may adversely affect outcomes. Incorporating substance use screening and treatments into prostate cancer care guidelines and coordination of care is desirable. Cancer 2014;120:3338–3345. © 2014 American Cancer Society.
