Overview:

Dr. Cohen's research program includes clinical research relating to aspects of the pathways to functional decline and reilience with aging, geriatric assessment, and cancer and anemia in the elderly.

Pathways to functional decline are being explored through the NIA funded Claude Pepper Older Americans Independence Center, and includes studies of the contributions of age related physiologic change, in particular changes in inflammatory parameters, comorbid diseases and conditions, environment, genetics, and the interactionas among them. Data are derived from several current studies as well as previously collected data sets from the Established Populations for Epidemiologic Studies of the Elderly (EPESE), National Long Term Care Survey, and the Chinese Longevity Study (with Dr. Zeng Yi). Previous work has demonstrated the important contributions of age related inflammation and coagulation activation to functional status. He is Co-PI of the Pepper Center Physical Performance Across the LifeSpan (PALS) study, which is a longitudinal cohort study of community dwelling adults from age 30-90+and includes functional measures and biomarkers on inflammation and metabolism.
 
Geriatric assessment approaches have been studied in a number of randomized and controlled studies and work is now concentrating on the application of Comprehensive Geriatric Assessment tools to the evaluation and treatment of elderly patients with cancer. This is an extension and continuation of a long standing interest in geriatric oncology. Previous studies have elucidated age-related patterns of disease presentation, treatment approaches, clinical trials, survivorship, quality of life, impact of comrobidities and functional outcomes. Dr. Cohen was co-chair, and now member of the Cancer in the Older Adult Committee of the Alliance for Clinical Trials in Oncology (ALLIANCE). A number of active studies and ongoing data bases aree being utilized to address these questions.


Anemia in the older adult is being addressed through an NIA funded U01 consortium (Dr. Cohen Co-PI). the current main study is an observational study followed by a pragmatic treatment trial for anemia in older adults with CHF, in collaboration with the Cardiovascular Research Network (CVRN) of the Health services research network (HSRN)

Perceptions of specialty palliative care and its role in pediatric stem cell transplant: A multidisciplinary qualitative study

Background: Consultation of specialty palliative care remains uncommon in pediatric stem cell transplant (SCT) despite growing evidence that early integration of palliative care improves outcomes in patients with advanced cancers or undergoing SCT. Little is known about how multidisciplinary pediatric SCT teams perceive palliative care and its role in SCT. Procedure: We conducted semistructured interviews of members of a multi-disciplinary SCT team to understand their perceptions of palliative care, how specialty palliative care is integrated into SCT, and to identify barriers to increased integration. Eligible participants included physicians, nurses, inpatient nurse practitioners, social workers, and child life specialists. Data were analyzed using thematic analysis. Results: Four major themes were identified. First, SCT team members held a favorable perception of the palliative care team. Second, participants desired increased palliative care integration in SCT. Third, participants believed that the palliative care team had insufficient resources to care for the large number of SCT patients, which led to the SCT team limiting palliative care consultation. And, finally, the lack of a standardized palliative care consultation process prevented greater integration of palliative care in SCT. Conclusions: SCT team members held a favorable perception of palliative care and saw a role for greater palliative care integration throughout the SCT course. We identified modifiable barriers to greater palliative care integration. SCT teams who desire greater palliative care integration may adapt and implement an existing model of palliative care integration in order to improve standardization and increase integration of specialty palliative care in SCT.

Predictors of Unplanned Hospitalizations Among Older Adults Receiving Cancer Chemotherapy.

PURPOSE: Hospitalizations during cancer treatment are costly, can impair quality of life, and negatively affect therapy completion. Our objective was to identify risk factors for unplanned hospitalization among older adults receiving chemotherapy. METHODS: This is a secondary analysis of a multisite cohort study (N = 750) of patients ≥ 65 years of age evaluated with a geriatric assessment (GA) to predict chemotherapy toxicity. The primary outcome of this analysis was unplanned hospitalizations during treatment; the secondary outcome was length of stay (LOS) of the first hospitalization. Independent variables included pretreatment GA measures, laboratory values, cancer type and stage, and treatment intensity characteristics. We used logistic regression to estimate the odds of hospitalization and generalized linear models for LOS in multivariable analyses. RESULTS: The sample median age was 72 years (range, 65-94 years); 59% had stage IV disease. At least one unplanned hospitalization occurred in 193 patients (25.7%) during receipt of chemotherapy. In multivariable analyses controlling for cancer type, the following baseline characteristics were significantly associated with increased odds of hospitalization: needing help bathing or dressing (odds ratio [OR], 1.8; 95% CI, 1.0 to 3.1), polypharmacy (≥ 5 meds) (OR, 1.6; 95% CI, 1.1 to 2.4), more comorbid conditions (OR, 1.1; 95% CI, 1.0 to 1.3), availability of someone to take them to the doctor (OR, 2.0; 95% CI, 1.0 to 4.1), CrCl < 60 mL/min (OR, 1.7; 95% CI, 1.1 to 2.4), and albumin < 3.5 g/dL (OR, 1.8; 95% CI, 1.2 to 2.8). In multivariable analyses, older age, self-reported presence of liver or kidney disease, living alone and depressive symptoms were associated with longer LOS. CONCLUSION: Readily available GA variables and laboratory data, but not age, were associated with unplanned hospitalizations among older adults receiving chemotherapy. If validated, these data can inform prediction models and the design of interventions to decrease unplanned hospitalizations.

Electronic Geriatric Assessment: Is It Feasible in a Multi-Institutional Study That Included a Notable Proportion of Older African American Patients? (Alliance A171603).

PURPOSE: This study determined whether an electronic version of the geriatric assessment is feasible in a multi-institutional, diverse setting. METHODS: Ten sites within the Alliance for Clinical Trials in Oncology participated. Patients who had active cancer or a history of cancer and were 65 years of age or older were eligible. The geriatric assessment was completed with an electronic data capture system that had been loaded onto iPads. Feasibility was defined a priori as completion in at least 70% of patients either with or without help. To enhance racial diversity, the original sample size was later changed and augmented by 50% with the intention of increasing enrollment of older minority patients. RESULTS: A total of one hundred fifty-four patients were registered with a median age of 72 years (range, 65-91 years). Forty-three (28%) identified themselves as African American or Black. One hundred forty-one patients (92%) completed the electronic geriatric assessment. Feasibility was observed across all subgroups, regardless of race, education, performance status, comorbidities, and cognition; 124 patients (81%) completed the geriatric assessment without help. Reasons for not completing the geriatric assessment are as follows: clinic visit did not occur (n = 6), no iPad connection to the Internet (n = 3), patient declined (n = 2), prolonged hospitalization (n = 1), and patient died (n = 1). Reasons for needing help, as reported by study personnel, were as follows: the patient preferred that research personnel ask the questions (n = 9), vision problem (n = 3), lack of comfort with the iPad (n = 2), questions were not clear (n = 1), less proficient in English (n = 1), and challenge in pressing the green button to go to the next question (n = 1). CONCLUSION: The electronic geriatric assessment is feasible in a multi-institutional setting that includes a notable proportion of African American or Black patients.

Factors associated with falls in older women with breast cancer: the use of a brief geriatric screening tool in clinic.

PURPOSE: Unintentional falls and breast cancer are common among older women, but the associations between them are understudied. We aimed to identify factors associated with falls in older women with breast cancer. METHODS: We retrospectively reviewed clinical records of older women with breast cancer at Duke Medical Center who had completed the Senior Adult Oncology Program geriatric assessment. Characteristics were compared between women had had at least one fall in the past year and those who did not. Pearson's Chi-square tests and t tests were used for comparison of groups' characteristics. Logistic regression determined factors associated with falling. RESULTS: We identified 425 women, age 76.2 years (range 65-89 years), at the time of the assessment. 118 (27.8%) women reported a fall in the prior year. Age, race, ethnicity, and time since diagnosis (all p > 0.05) were similar between groups. In univariate analyses, metastatic disease (p = 0.023) and history of endocrine therapy (p = 0.042) were more common among women who fell. Women who fell had lower systolic (p = 0.001), diastolic (p < 0.001) blood pressures, and SpO2 (p = 0.018). Women who had fallen had a higher Charlson Comorbidity Index (CCI: p = 0.033), and were more likely to report using a walking aide (p < 0.001), nutritional issues (p = 0.006), and depression symptoms (p = 0.038). In multivariate analysis, falling was associated with low DBP (OR 0.93; p = 0.0017), low SpO2 (OR 0.79; p = 0.0169), a higher CCI (OR 1.23; p = 0.0076), and depression symptoms (OR 1.61; p = 0.039). CONCLUSIONS: Among older women with breast cancer, depressive symptoms, higher comorbidity level, and vital sign measurements were associated with having fallen.
