In the United States, racial/ethnic minority, rural, and low-income populations continue to experience suboptimal access to and quality of health care despite decades of recognition of health disparities and policy mandates to eliminate them. Many health care interventions that were designed to achieve health equity fall short because of gaps in knowledge and translation. We discuss these gaps and highlight innovative interventions that help address them, focusing on cardiovascular disease and cancer. We also provide recommendations for advancing the field of health equity and informing the implementation and evaluation of policies that target health disparities through improved access to care and quality of care.

Objective To investigate protein intakes across demographic characteristics in relation to dietary patterns and functional outcomes in older adults. Design Observational and cross-sectional study. Setting Non-institutionalized participants from the 2005–2014 National Health and Nutrition Examination Survey. Participants Data from 11,680 adults were categorized into 51–60 years (n= 4,016), 61–70 years (n=3,854), and 71 years and older (n=3,810) for analysis. Measurements Adults were stratified by meeting or not meeting the protein recommendation (0.8 g/kg/d) to compare demographics, diet quality with Healthy Eating Index– 2015, functional limitations, and other dietary intakes. Dietary recalls were collected using the multiple pass method. Data analyses were weighted to create a nationally–representative sample. Results Dietary protein intakes were significantly lower in older age groups, with up to 46% of the oldest adults not meeting the protein intake recommendation. Participants consuming protein below the recommended intake level had significantly poorer diet quality across all age groups (P<0.01), however, overall diet quality was better in older adults. Those not meeting the protein recommendation were more likely to have intakes of other nutrients below recommended levels. Those below the protein recommendation had significantly more functional limitations across all age groups, while grip strength was significantly lower in those over 70 years old. Conclusion Lower protein intakes, and lower diet quality and physical functioning are related in an aging population. Meeting the protein recommendation was linked to better overall diet quality and may be protective of lean mass; therefore, evaluation of individual characteristics which may affect protein intakes is crucial in supporting older adults to meet their protein needs.

BackgroundPatient navigation (PN) is a patient-centered health-care service delivery model that assists individuals, particularly the medically underserved, in overcoming barriers (e.g., personal, logistical, and system) to care across the cancer care continuum. In 2012, the American College of Surgeons Commission on Cancer (CoC) announced that health-care facilities seeking CoC-accreditation must have PN processes in place starting January 1, 2015. The CoC mandate, in light of the recent findings from centers within the Patient Navigation Research Program and the influx of PN interventions, warrants the present literature review.MethodsPubMed and Medline were searched for studies published from January 2010 to October 2015, particularly those recent articles within the past 2 years, addressing PN for breast and gynecological cancers, and written in English. Search terms included patient navigation, navigation, navigator, cancer screening, clinical trials, cancer patient, cancer survivor, breast cancer, gynecological cancer, ovarian cancer, uterine cancer, vaginal cancer, and vulvar cancer.ResultsConsistent with prior reviews, PN was shown to be effective in helping women who receive cancer screenings, receive more timely diagnostic resolution after a breast and cervical cancer screening abnormality, initiate treatment sooner, receive proper treatment, and improve quality of life after cancer diagnosis. However, several limitations were observed. The majority of PN interventions focused on cancer screening and diagnostic resolution for breast cancer. As observed in prior reviews, methodological rigor (e.g., randomized controlled trial design) was lacking.ConclusionFuture research opportunities include testing PN interventions in the post-treatment settings and among gynecological cancer patient populations, age-related barriers to effective PN, and collaborative efforts between community health workers and patient navigators as care goes across segments of the cancer control continuum. As PN programs continue to develop and become a standard of care, further research will be required to determine the effectiveness of cancer PN across the cancer care continuum, and in different patient populations.

Purpose:This study tested the feasibility and efficacy of using a text-based intervention to increase initiation, decrease discontinuation, and improve adherence as prescribed to adjuvant hormone therapy (AHT) among hyphenate post-menopausal breast cancer survivors.Methods:The 3-month intervention consisted of daily text message reminders to take medication, coupled with a dynamic (eg, feedback on progress) tailored intervention using weekly interactive surveys delivered by a smartphone app. Five clinic sites within the Alliance for Clinical Trials in Oncology participated. Hormone levels were measured prior to AHT initiation and at study exit.Results:Of the 39 patients recruited to the pilot study, 27 (69.2%) completed all study requirements (completed both the baseline and the exit surveys, both blood draws, and did not miss more than 2 weekly surveys). Significant improvements were observed pre- to postintervention for self-reported medication adherence (P = .015), mental health functioning (P = .007), and perceived stress (P = .04). Significant decreases in estradiol, estrogen, and estrone hormone levels were observed from baseline to study exit (P < .001), indicating the accuracy of self-reported AHT adherence. Participants (91.9%) and physicians (100%) agreed that participant participation in the intervention was beneficial.Conclusions:The results of this pilot study established the general feasibility and efficacy of an app-based intervention to support patient AHT adherence. Larger controlled, randomized trials are needed to examine the effectiveness of the app-based intervention in improving AHT and quality of life among breast cancer survivors.

Background Uptake of the human papillomavirus (HPV) vaccine is low in Appalachian Ohio, and area with high cervical cancer rates. Methods We conducted a group-randomized trial among 12 counties in Appalachian Ohio randomized to receive either an HPV vaccine (intervention counties) or influenza vaccine (comparison counties) multi-level intervention (MLI). Parents (n=337) who had a daughter aged 9 to 17 years who had not received the HPV vaccine were recruited from commercial lists. Clinics (N=24) and 119 providers from these clinics were also recruited. The primary outcome was medical record confirmed receipt of the first shot of the HPV vaccine three months after receiving the intervention among daughters of parents enrolled in the study. Secondary outcomes included receipt of the first HPV vaccine shot by 6 months and changes in provider knowledge. Results According to medical records, 10 (7.7%) daughters of intervention participants received the first shot of the HPV vaccine within three months of being sent the intervention materials compared to 4 (3.2%) daughters of comparison group participants (p=0.061). By six months, 17 (13.1%) daughters of intervention participants received the first HPV vaccine shot compared to eight (6.5%) daughters of comparison group participants (p=0.002). Provider knowledge about HPV increased (p<0.001, from baseline to post-education). Conclusions The MLI increased uptake of the HPV vaccine among girls aged 9 to 17 years, however, uptake was low. Impact To improve HPV vaccine uptake, attention to additional levels of influence (e.g., policy, community) and more elements within levels (e.g., reminders, automated prompts) may be needed.
