Background: Medication non-adherence is common among<br />
older adults with chronic co-morbidity, but the underlying factors are<br />
largely unexplored. This study examines the prevalence and correlates<br />
of self-reported medication non-adherence among communitydwelling<br />
older adults with chronic cardiovascular conditions (i.e., diabetes<br />
mellitus [DM], coronary heart disease [CHD], and/or<br />
hypertension [HTN]).<br />
Methods: The study sample (mean [SD] age 82.1 [2.8], 52.5% female,<br />
37.0% black) included 897 members from the Health Aging<br />
and Body Composition cohort (n=3075) with any DM (n=338;<br />
37.7%), CHD (n=381; 42.5%), or HTN (684; 76.3%) at year 10. Selfreported<br />
medication non-adherence was measured by the 4-item<br />
Morisky Medication Adherence Scale (MMAS) and 2-item Cost-Related<br />
Non-Adherence scale (CRN) at year 11; these scales separately<br />
assess different reasons for medication non-adherence. We used multivariable<br />
logistic regression models with backward selection to identify<br />
correlates (i.e., demographic, health status, and access to care factors)<br />
of non-adherence for each measure.<br />
Results: Non-adherence by MMAS and CRN was reported by<br />
40.7% and 7.7%, respectively. Non-adherence by MMAS was associated<br />
with black race (adjusted odds ratio=AOR=1.85, 95% interval=1.25-2.74)<br />
and hospitalization in the previous 6 months<br />
(AOR=1.97, 95% interval=1.22-3.17). Non-adherence by CRN was<br />
associated with marital status (married vs. unmarried; AOR=0.47,<br />
95% interval=0.23-0.98) and money-related delay in medical care<br />
(AOR=6.94, 95% interval=2.41-19.97). Age, gender, and the total<br />
number of regularly scheduled medications were not associated with<br />
non-adherence by either MMAS or CRN.<br />
Conclusions: Self-reported medication non-adherence is common<br />
in older adults with chronic cardiovascular conditions, and nonadherence<br />
measured by CRN is less prevalent than MMAS. No correlates<br />
for non-adherence were detected consistently across both<br />
measures. Future studies should evaluate targeted interventions<br />
based on patient-specific modifiable barriers to improve medication<br />
adherence.<br />

Health Care Proxy Involvement and Satisfaction in Decision-<br />
Making for the Treatment of Infections in Nursing Home Residents<br />
with Advanced Dementia.<br />

Background: Infections are common in advanced dementia, and<br />
health care proxies (HCPs) are often called upon to make treatment<br />
decisions. This study describes the awareness, involvement, and satisfaction<br />
of HCPs in decision making regarding infectious episodes for<br />
a cohort of nursing home (NH) residents with advanced dementia.<br />
Methods: From 2010-2011, data were prospectively collected<br />
from 135 NH residents with advanced dementia and their HCPs at 22<br />
Boston area facilities. For each infectious episode, information was<br />
obtained on whether the HCP: 1. could be contacted by study staff; 2.<br />
was aware of the infection; and 3. was involved in decision making.<br />
Multivariable logistic regression was used to determine resident,<br />
HCP and episode characteristics associated with HCP awareness of<br />
the infectious episode.<br />
Results: Residents experienced 287 infectious episodes (82 respiratory,<br />
114 urinary tract infection, 37 skin and 53 fever). HCPs were<br />
able to be contacted by study staff for 217/287 episodes. Once contacted,<br />
HCPs were aware of 94/217 (43%) of episodes, and of these,<br />
were involved in decision-making for 57/94 (61%). HCP awareness of<br />
the episode was associated with the HCP being the child of the resident<br />
(vs. other relationship) [adjusted odds ratio (AOR) 2.34, 95% CI<br />
1.19 – 4.59], female (AOR 2.79, 1.37-5.66), and the episode being<br />
treated with antibiotics (AOR 3.68, 1.56-8.66).<br />
Conclusions: The majority of infectious episodes in NH residents<br />
with advanced dementia do not involve HCPs in decision-making.<br />
Awareness of infections among HCPs is more likely for episodes<br />
treated with antibiotics, and when the HCP is the resident’s child and<br />
is female. These factors may help target infectious episodes that require<br />
greater attention with respect to better informing HCPs of their<br />
loved one’s health status.<br />

Can a patient navigator get older patients and their oncologists on<br />
the same page?<br />

Background Older patients may approach cancer management<br />
decisions differently than younger patients. Although older patients<br />
may be more concerned about quality of life than cure, oncologists do<br />
not routinely elicit patients’ quality of life concerns. As a result, older<br />
patients and their oncologist may not be on the same page during office<br />
visits.<br />
We undertook a two phase pilot study to test whether a patient<br />
navigator intervention could facilitate shared decision-making between<br />
older patients with cancer and their oncologists.<br />
Methods In the study’s first phase, we interviewed oncologists,<br />
older cancer patients, and their family members about their decisionmaking,<br />
and whether/how a patient navigator might help. Interviews<br />
were recorded, transcribed, and analyzed using grounded theory<br />
methods.<br />
In the second phase, the patient navigator met with an older patient<br />
prior to an oncology appointment to identify his/her quality of<br />
life and other concerns. The navigator then accompanied the patient<br />
to the oncology appointment and debriefed afterwards. Several days<br />
later, an investigator debriefed separately with the oncologist and the<br />
patient/family. Content analysis and descriptive statistics were used to<br />
analyze study data.<br />
Results In the first phase, we recruited 9 oncologists from 2 clinics,<br />
12 of their patients, and 3 of their family members. Oncologists<br />
and patients thought navigators could be helpful by clarifying understanding,<br />
taking notes, and helping patients ask questions.<br />
In the second phase, the 9 oncologists identified 9 additional patients.<br />
Prior to the navigated visits, patients identified their main concerns<br />
(mean 3 concerns, range 1-5). During the visits, the navigator reminded<br />
the patient of concerns in 4 visits, facilitated discussion about<br />
referral to a pain specialist in 1 visit, clarified referral to a cardiologist<br />
in 1 visit, and clarified the follow up plan with the oncologist in 2 visits.<br />
Patients described the navigator as helpful, reported that all their<br />
