The development of academic geriatric medicine: progress toward preparing the nation's physicians to care for an aging population.

Academic geriatric medicine programs are critical for training the physician workforce to care effectively for aging Americans. This article describes the progress made by medical schools in developing these programs. Academic leaders in geriatrics at all 145 accredited allopathic and osteopathic medical schools in the United States were surveyed in the winter of 2005 (68% response rate) and results compared with findings from a similar 2001 survey. Physician faculty in geriatrics at U.S. medical schools increased from 7.5 (mean) full‐time equivalents (FTEs) in 2001 to 9.6 FTEs in 2005. Faculty and staff effort is mostly devoted to clinical practice (mean 36.9%) and education (mean 34.6%). A small number of programs focus on research; only six responding schools devote more than 40% of faculty effort to research. Seventy‐one percent reported that their medical school required a geriatrics medical student clerkship or that their geriatric training was integrated into a required clinical rotation. In summary, from 2001 to 2005, more fellows and faculty have been recruited and trained, and some academic programs have emerged with strong education, research, and clinical initiatives. Medical student exposure to geriatrics curriculum has increased, although few academic geriatricians are pursuing research careers, and the number of practicing geriatricians is declining. An expanded investment in training the physician workforce to care for older adults will be required to ensure adequate care for aging Americans.

Are Internal Medicine Residency Programs Adequately Preparing Physicians to Care for the Baby Boomers? A National Survey from the Association of Directors of Geriatric Academic Programs Status of Geriatrics Workforce Study

Patients aged 65 and older account for 39% of ambulatory visits to internal medicine physicians. This article describes the progress made in training internal medicine residents to care for older Americans. Program directors in internal medicine residency programs accredited by the Accreditation Council for Graduate Medical Education were surveyed in the spring of 2005. Findings from this survey were compared with those from a similar 2002 survey to determine whether any changes had occurred. A 60% response rate was achieved (n=235). In these 3‐year residency training programs, 20 programs (9%) required less than 2 weeks of clinical instruction that was specifically structured to teach geriatric care principles, 48 (21%) at least 2 weeks but less than 4 weeks, 144 (62%) at least 4 weeks but less than 6 weeks, and 21 (9%) required 6 or more weeks. As in 2002, internal medicine residency programs continue to depend on nursing home facilities, geriatric preceptors in nongeriatric clinical ambulatory settings, and outpatient geriatric assessment centers for their geriatrics training. Training was most often offered in a block format. The mean number of physician faculty per residency program dedicated to teaching geriatric medicine was 3.5 full‐time equivalents (FTEs) (range 0–50), compared with a mean of 2.2 FTE faculty in 2002 (P≤.001). Internal medicine educators are continuing to improve the training of residents so that, as they become practicing physicians, they will have the knowledge and skills in geriatric medicine to care for older adults.

National Survey of Geriatric Medicine Fellowship Programs: Comparing Findings in 2006/07 and 2001/02 from the American Geriatrics Society and Association of Directors of Geriatric Academic Programs Geriatrics Workforce Policy Studies Center

This article documents the development of geriatric medicine fellowship training in the United States through 2009. Results from a national cross‐sectional survey of all geriatric medicine fellowship training programs conducted in 2007 is compared with results from a similar survey in 2002. Secondary data sources were used to supplement the survey results. The 2007 survey response rate was 71%. Sixty‐seven percent of responding programs directors have completed formal geriatric medicine fellowship training and are board certified in geriatrics, and 29% are board certified through the practice pathway. The number of Accreditation Council for Graduate Medical Education–accredited fellowship programs has slowly increased, from 120 (23 family medicine (FM) and 97 internal medicine (IM)) in 2001/02 to 145 in 2008/09 (40 FM and 105 IM), resulting in a 21% increase in fellowship programs and a 13% increase in the number of first‐year fellows (259 to 293). In 2008/09, the growth in programs and first‐year slots, combined with the weak demand for geriatrics training, resulted in more than one‐third of first‐year fellow positions being unfilled. The number of advanced fellows decreased slightly from 72 in 2001/00 to 65 in 2006/07. In 2006/07, 55% of the advanced fellows were enrolled at four training programs. In 2008/09, 66% of fellows were international medical school graduates. The small numbers of graduating geriatric medicine fellows are insufficient to care for the expanding population of older frail patients, train other disciples in the care of complex older adults, conduct research in aging, and be leaders in the field.

Application of a Decision Support Tool for Anticoagulation in Patients with Non-valvular Atrial Fibrillation

BackgroundAtrial fibrillation affects more than two million Americans and results in a fivefold increased rate of embolic strokes. The efficacy of adjusted dose warfarin is well documented, yet many patients are not receiving treatment consistent with guidelines. The use of a patient-specific computerized decision support tool may aid in closing the knowledge gap regarding the best treatment for a patient.MethodsThis retrospective, observational cohort analysis of 6,123 Ohio Medicaid patients used a patient-specific computerized decision support tool that automated the complex risk–benefit analysis for anticoagulation. Adverse outcomes included acute stroke, major gastrointestinal bleeding, and intracranial hemorrhage. Cox proportional hazards models were developed to compare the group of patients who received warfarin treatment with those who did not receive warfarin treatment, stratified by the decision support tool’s recommendation.ResultsOur decision support tool recommended warfarin for 3,008 patients (49%); however, only 9.9% received warfarin. In patients for whom anticoagulation was recommended by the decision support tool, there was a trend towards a decreased hazard for stroke with actual warfarin treatment (hazard ratio 0.90) without significant increase in gastrointestinal hemorrhage (0.87). In contrast, in patients for whom the tool recommended no anticoagulation, receipt of warfarin was associated with statistically significant increased hazard of gastrointestinal bleeding (1.54, p = 0.03).ConclusionsWe have shown that our atrial fibrillation decision support tool is a useful predictor of those at risk of major bleeding for whom anticoagulation may not necessarily be beneficial. It may aid in weighing the benefits versus risks of anticoagulation treatment.

The Development of Academic Geriatric Medicine in the United States 2005 to 2010: An Essential Resource for Improving the Medical Care of Older Adults

Academic geriatric medicine programs are critical for training the physician workforce to care effectively for aging Americans. This article updates the progress made by U.S. medical schools from 2005 to 2010 in developing these programs. Academic leaders in geriatrics in accredited allopathic and osteopathic medical schools were surveyed in the winter of 2010 (60% response rate), and results were compared with findings from a similar 2005 survey (68% response rate). Physician faculty in geriatrics increased from 9.6 (mean) full‐time equivalents (FTEs) in 2005 to 11.2 by 2010. In 2010, faculty and staff effort was mostly devoted to clinical practice (mean = 37%) and education (mean = 33%), with only seven responding schools devoting more than 40% of faculty effort to research. Schools that have been designated as Centers of Excellence had a median 20 FTE physician faculty, compared with seven at the other schools (P < .001). In 2010, 27% of medical schools required a geriatrics clerkship, and 87% (n = 83) had an elective geriatric clerkship. In summary, more fellows and faculty were recruited and trained in 2010 than in 2005, and some academic programs have emerged with strong education, research, and clinical initiatives. Medical student exposure to geriatrics curriculum has increased, but few academic geriatricians are pursuing research careers, and the number of practicing geriatricians is declining. New approaches to training the entire physician workforce to care for older adults will be required to ensure adequate medical care for aging Americans.

Occupational exposure to trichloroethylene and cancer risk for workers at the Paducah Gaseous Diffusion Plant.

ObjectiveThe Paducah Gaseous Diffusion Plant (PGDP) became operational in 1952; it is located in the western part of Kentucky. We conducted a mortality study for adverse health effects that workers may have suffered while working at the plant, including exposures to chemicals.Materials and MethodsWe studied a cohort of 6820 workers at the PGDP for the period 1953 to 2003; there were a total of 1672 deaths to cohort members. Trichloroethylene (TCE) is a specific concern for this workforce; exposure to TCE occurred primarily in departments that clean the process equipment. The Life Table Analysis System (LTAS) program developed by NIOSH was used to calculate the standardized mortality ratios for the worker cohort and standardized rate ratio relative to exposure to TCE (the U.S. population is the referent for ageadjustment). LTAS calculated a significantly low overall SMR for these workers of 0.76 (95% CI: 0.72–0.79). A further review of three major cancers of interest to Kentucky produced significantly low SMR for trachea, bronchus, lung cancer (0.75, 95% CI: 0.72–0.79) and high SMR for Non-Hodgkin’s lymphoma (NHL) (1.49, 95% CI: 1.02–2.10).ResultsNo significant SMR was observed for leukemia and no significant SRRs were observed for any disease. Both the leukemia and lung cancer results were examined and determined to reflect regional mortality patterns. However, the Non-Hodgkin’s Lymphoma finding suggests a curious amplification when living cases are included with the mortality experience.ConclusionsFurther examination is recommended of this recurrent finding from all three U.S. Gaseous Diffusion plants.

Geriatrics Education in Psychiatric Residencies: A National Survey of Program Directors

ObjectiveThe authors describe the current characteristics of geriatrics training within general psychiatry training programs.MethodsIn the fall of 2006, a survey was mailed and made available online to all U.S. psychiatric residency program directors (N=181).ResultsThe response rate was 54% (n = 97). Of the responding psychiatry programs, 96% (n = 93) required a clinical experience in geriatrics, with a mean of 54.9 half days of required clinical training. The predominant training sites were inpatient geriatric psychiatry acute care units, ambulatory care experiences precepted by one or more geriatric psychiatrists, and outpatient geriatric psychiatry assessment centers. The mean number of physician faculty per residency program available to teach geriatrics was 2.8 full-time equivalents, and the mean number of physicians certified in geriatric psychiatry was 3.2 per program. Conflicting time demands with other curricula was ranked as the most significant barrier to expanding geriatrics training.ConclusionVariability in the amount of time devoted to geriatrics training exists across general psychiatric residency programs. Some residents spend very little time in specific required geriatric psychiatry clinical experiences and have limited exposure to well-trained geriatric psychiatrists. Therefore, some psychiatrists who will take care of older patients in the future may be ill prepared to do so.

Estimation of radon exposures to workers at the Fernald Feed Materials Production Center 1952–1988

The Feed Materials Production Center (FMPC) at Fernald, Ohio produced uranium metal products for use in Department of Energy defense programs. Radium-contaminated waste material was stored on-site in two K-65 silos on the west side of the facility and provided a source of 222Ra. The initial objective of this study was to estimate radon exposures to employees at FMPC working from 1952 to 1988. A modified Gaussian plume model was used to estimate exposures to workers. In an effort to validate these model-based estimates, we used 138 CR-39 film assays from window glass sampled in buildings throughout the site. Results from the CR-39 assays indicated a second substantial source of radon, the smaller Q-11 silos located in the production area. A response-surface regression analysis using a cubic spline model was fit to the CR-39 data to estimate 210Po surface activity levels at geographic coordinates throughout the facility. Knowledge of the age of the glass, the amount of contaminated waste in the Q-11 silos, and 210Po decay rates were used to estimate annual exposures to radon decay products (WLM: working level months). Estimated WLM levels associated with the Q-11 source term indicated that employees working in the vicinity during the period when they were filled with radium-contaminated waste (1952–1958) received substantially higher radon exposures than those from the K-65 source during this period. Results of the two models, corresponding to the K-65 and Q-11 sources, were combined to estimate WLM levels by year for each of the 7143 Fernald workers during the period 1952–1988. Estimated cumulative exposures to individual workers ranged from <0.5 to 751 WLM. Estimated radon exposures from this newly discovered source have important implications for future epidemiologic studies of lung cancer in workers at the Fernald facility.
