Clinical Preventive Services for Older Adults: The Interface Between Personal Health Care and Public Health Services

Healthy aging must become a priority objective for both population and personal health services, and will require innovative prevention programming to span those systems. Uptake of essential clinical preventive services is currently suboptimal among adults, owing to a number of system- and office-based care barriers. To achieve maximum health results, prevention must be integrated across community and clinical settings. Many preventive services are portable, deliverable in either clinical or community settings. Capitalizing on that flexibility can improve uptake and health outcomes. Significant reductions in health disparities, mortality, and morbidity, along with decreases in health spending, are achievable through improved collaboration and synergy between population health and personal health systems.

Improving access to mammograms through community-based influenza clinics. A quasi-experimental study.

BACKGROUND It is a national priority to increase breast-cancer screening among women aged > or = 50. Annual influenza clinics may represent an efficient setting in which to promote breast-cancer screening among older women. To our knowledge, this possibility has not previously been explored. OBJECTIVE To examine whether offering women attending community-based influenza clinics the opportunity to receive a scheduling telephone call from a mammography facility will result in an increase in the number of mammograms performed over a 6-month period. METHODS We used a quasi-experimental design with 6-month follow-up. A contemporaneous population-based survey provided a further control group for comparison. The sample group consisted of a total of 284 women attending nine community-based influenza clinics in a semirural county in Connecticut. All women were aged > or = 50 and reported no mammogram in the preceding 12 months. All women received informational literature on mammography. Experimental subjects were each asked if a radiology facility chosen by the subject could call her at home to schedule a mammogram. Mammograms performed were determined by hospital record for participants who received a scheduling call from a radiology facility, and by self-report for all other participants. RESULTS Mammography use following access through influenza clinics was approximately twice that of women attending influenza clinics where access to mammography was not offered. Using three different assumptions regarding participants whose mammography status was unknown, the relative risks ranged between 1.6 and 2.1. For each assumption the results were statistically significant (chi(2)=8.51-12.2; p<0.001). CONCLUSIONS Linking access to mammography at community-based influenza clinics can significantly increase the use of mammograms among women aged > or = 50. Further studies should seek to confirm these findings and determine the degree to which they can be replicated in a variety of communities. Enhancing preventive health practice through the bundling of services suggests a new strategy to exploit available interventions to improve health.

Vaccinations and preventive screening services for older adults: opportunities and challenges in the USA

Vaccinations and disease-screening services occupy an important position within the constellation of interventions designed to prevent, forestall or mitigate illness: they straddle the worlds of clinical medicine and public health. This paper focuses on a set of clinical preventive services that are recommended in the USA for adults aged 65 and older, based on their age and gender. These services include immunisations against influenza and pneumococcal disease, and screening for colorectal and breast cancers. We explore opportunities and challenges to enhance the delivery of these interventions, and describe some recently developed models for integrating prevention efforts based in clinician offices and in communities. We also report on a state-level surveillance measure that assesses whether older adults are ‘up to date’ on this subset of preventive services. To better protect the health of older Americans and change the projected trajectory of medical costs, expanded delivery of recommended vaccinations and disease screenings is likely to remain a focus for both US medicine and public health.

Developing an integrated strategy to reduce ethnic and racial disparities in the delivery of clinical preventive services for older Americans.

OBJECTIVES To determine the optimum strategy for increasing up-to-date (UTD) levels in older Americans, while reducing disparities between White, Black, and Hispanic adults, aged 65 years and older. METHODS Data were analyzed from the 2008 Behavioral Risk Factor Surveillance System, quantifying the proportion of older Americans UTD with influenza and pneumococcal vaccinations, mammograms, Papanicolaou tests, and colorectal cancer screening. A comparison of projected changes in UTD levels and disparities was ascertained by numerically accounting for UTD adults lacking 1 or more clinical preventive services (CPS). Analyses were performed by gender and race/ethnicity. RESULTS Expanded provision of specific vaccinations and screenings each increased UTD levels. When those needing only vaccinations were immunized, there was a projected decrease in racial/ethnic disparities in UTD levels (2.3%-12.2%). When those needing only colorectal cancer screening, mammography, or Papanicolaou test were screened, there was an increase in UTD disparities (1.6%-4.5%). CONCLUSIONS A primary care and public health focus on adult immunizations, in addition to other CPS, offers an effective strategy to reduce disparities while improving UTD levels.

Linear association between number of modifiable risk factors and multiple chronic conditions: Results from the Behavioral Risk Factor Surveillance System

Multiple (≥2) chronic conditions (MCCs) are responsible for a large fraction of healthcare costs. Our aim was to examine possible associations between MCCs and composite measures of behavioral risk factors (RFs). Data were publicly available 2013 Behavioral Risk Factor Surveillance System and included 483,865 non-institutionalized US adults ages ≥18years. Chronic conditions included asthma, arthritis, chronic obstructive pulmonary disease, cognitive impairment, heart disease, stroke, cancer, and kidney disease. RFs included obesity, current smoking, sedentary lifestyle, inadequate fruit and vegetable consumption, and sleeping other than 7-8h, while depression, hypertension, high cholesterol, and diabetes were considered in each category. Stata was used to study associations between 2 different MCCs and 2 composite measures of RFs in both unadjusted and adjusted analysis. Over 96% of respondents reported ≥1 of the 9 RFs and 71.5% reported ≥1 of the chronic conditions. For each combination there was a linear increase (with similar slopes) in MCC rate with more RFs and a statistically significant increase in adjusted odds ratios (ORs) for the MCC with each additional RF. For the MCC based on 8 chronic conditions, ORs were 1.3 (95% CI 1.1, 1.6) for 1 RF, 2.3 (1.9, 2.7) for 2, 3.7 (3.1, 4.4) for 3, 5.7 (4.8, 6.8) for 4, 9.1 (7.6, 10.8) for 5, 14.6 (12.2, 17.4) for 6, 24.0 (19.7, 29.2) for 7, 38.1 (29.6, 48.9) for 8, and 100.0 (56.3, 177.8) for all 9, each vs. zero RFs. Findings highlight the need for effective integrated programs to address multiple RFs and chronic conditions.

Polling Places, Pharmacies, and Public Health: Vote & Vax 2012

US national elections, which draw sizable numbers of older voters, take place during flu-shot season and represent an untapped opportunity for large-scale delivery of vaccinations. In 2012, Vote & Vax deployed a total of 1585 clinics in 48 states; Washington, DC; Guam; Puerto Rico; and the US Virgin Islands. Approximately 934 clinics were located in pharmacies, and 651 were near polling places. Polling place clinics delivered significantly more vaccines than did pharmacies (5710 vs 3669). The delivery of vaccines was estimated at 9379, and approximately 45% of the recipients identified their race/ethnicity as African American or Hispanic. More than half of the White Vote & Vax recipients and more than two thirds of the non-White recipients were not regular flu shot recipients.
