[Teachers' assessment practices in context of nursing clinical education : a qualitative descriptive study.] / Les pratiques évaluatives d'enseignants en soins infirmiers lors des stages : une étude descriptive qualitative.

Since no study has yet been able to assess the Quebec portrait of teachers' evaluation practices in the context of clinical education in nursing. Considering the importance of clinical teaching and evaluation in the education of nursing students, this study is justified. This article presents the results of a study that aimed to describe and understand the experience of teachers in the ongoing assessment of nursing students' learning during clinical education. It aimed to describe the evaluation practices of teachers during the learning of students in clinical education and achievement context, and to identify factors influencing these practices. In the context of descriptive qualitative research, the data collection was mainly based on the description of practices reported and collected during interviews realized with 10 nursing teachers of a college of the region of Saguenay-Lac-Saint-Jean (SLSJ, Quebec, Canada). The results allowed, for instance, to identify and to describe the evaluation practices led in this specific context of the study : the direct and indirect observation ; the questions asked to the sudent and to the group of sutdents and individual and group feed-back. They also allowed to enumerate and to categorize factors which can influence these practices, that is facilitates factors, barriers and faiths.

Hysterectomy and urinary incontinence in postmenopausal women.

INTRODUCTION AND HYPOTHESIS: To evaluate an association between hysterectomy and urinary incontinence (UI) in postmenopausal women. METHODS: Women (aged 50-79) with uteri (N = 53,569) and without uteri (N = 38,524) who enrolled in the Women's Health Initiative (WHI) Observational Study between 1993 and 1996 were included in this secondary analysis. Baseline (BL) and 3-year demographic, health/physical forms and personal habit questionnaires were used. Statistical analyses included univariate and logistic regression methods. RESULTS: The baseline UI rate was 66.5 %, with 27.3 % of participants having stress urinary incontinence (SUI), 23 % having urge UI (UUI), and 12.4 % having mixed UI (MUI). 41.8 % of women had undergone hysterectomy, with 88.1 % having had the procedure before age 54. Controlling for health/physical variables, hysterectomy was associated with UI at BL (OR 1.25, 95 % CI 1.19, 1.32) and over the 3-year study period (OR 1.23, 95 % CI 1.11, 1.36). Excluding women with UI at BL, a higher incidence of UUI and SUI episodes was found in hysterectomy at year 3. Among women who had undergone hysterectomy, those with bilateral oophorectomy (BSO) did not have increased odds of developing UI at BL or over the 3-year study period. Hormone use was not associated with a change in UI incidence (estrogen + progesterone, p = 0.17; unopposed estrogen, p = 0.41). CONCLUSIONS: Risk of UI is increased in postmenopausal women who had undergone hysterectomy compared with women with uteri.

Combining quality improvement and geriatrics training: the nursing home polypharmacy outcomes project.

To examine sustained effects of an educational intervention, the authors repeated a successful quality improvement (QI) project on medication safety and cost effectiveness. In October 2007 and August 2008, the facility leadership and geriatrics faculty identified all patients receiving nine or more medications (polypharmacy cohort) in a 170-bed teaching nursing home. They then taught Geriatric Medicine fellows (n = 12 in 2007, 11 in 2008) to (a) systematically collect medication data; (b) generate medication recommendations (stop, taper, or continue) based on expert criteria (Beers criteria) or drug-drug interaction programs; (c) discuss recommendations with patients' attending physicians; and (d) implement approved recommendations. Over the two projects, the polypharmacy cohorts demonstrated decreased potentially inappropriate medications (odds ratio [OR] = .78, 95% confidence interval [95% CI] [0.69, 0.88], p < .001), contraindicated medications (OR = .63, 95% CI [0.47, 0.85], p = .002) and medication costs (OR = .97, 95% CI [0.96, 0.99], p < .001). Findings suggest that programs planning educational QI projects for trainees may benefit from a multiyear approach to maximize clinical and educational benefits.

Assessing trainee's performance using reported observations: Perceptions of nurse meta-assessors.

BACKGROUND: Educational and health care organizations who prepare meta-assessors to fulfill their role in the assessment of trainees' performance based on reported observations have little literature to rely on. While the assessment of trainees' performance based on reported observations has been operationalized, we have yet to understand the elements that can affect its quality fully. Closing this gap in the literature will provide valuable insight that could inform the implementation and quality monitoring of the assessment of trainees' performance based on reported observations. OBJECTIVES: The purpose of this study was to explore the elements to consider in the assessment of trainees' performance based on reported observations from the perspectives of meta-assessors. METHODS: Design, Settings, Participants, data collection and analysis. The authors adopted Sandelowski's qualitative descriptive approach to interview nurse meta-assessors from two nursing programs. A semi-structured interview guide was used to document the elements to consider in the assessment of nursing trainees' performance based on reported observations, and a survey was used to collect sociodemographic data. The authors conducted a thematic analysis of the interview transcripts. RESULTS: Thirteen meta-assessors participated in the study. Three core themes were identified: (1) meta-assessors' appropriation of their perceived assessment roles and activities, (2) team climate of information sharing, and (3) challenges associated with the assessment of trainees' performance based on reported observations. Each theme is comprised of several sub themes. CONCLUSIONS: To optimize the quality of the assessment of the trainee's performance based on reported observations and ratings, HPE programs might consider how to clarify better the meta-assessor's roles and activities, as well as how interventions could be created to promote a climate of information sharing and to address the challenges identified. This work will guide educational and health care organizations for better preparation and support for meta-assessors and preceptors.

Rapid Cycle Quality Improvement of Telemedicine Protocols in a Skilled Nursing Facility During the COVID-19 Pandemic.

Prior to the COVID-19 pandemic, telemedicine was not well adopted in US nursing facilities. Many nursing facilities have since acknowledged its value due to the need for stricter infection control and reduction of exposure risk from face-to-face visits. A quality improvement project was conducted to improve telemedicine protocols in a high-volume post-acute care nursing facility, enhance provider and facility capability for visits, improve attitudes and skills toward telemedicine, and expand patient access to medical care during the pandemic. Process improvement was facilitated through identifying core areas of need and implementing interventions to address them. Project impact was measured by a retrospective pre-post survey of 7 questions to evaluate process improvement, attitudes, skills, and perceptions using a 5-point Likert scale (5=strongly agree, 1=strongly disagree) completed by 22 respondents (8 medical providers and 14 staff). Scores from before and after implementation were compared using paired t-tests. Respondents expressed improvement in perceived value (3.2 vs 4.8), personal skill/efficiency (2.3 vs 4.2), comfort level (2.3 vs 4.5), and scheduling process (2.3 vs 3.9) for telemedicine visits (all P≤.001). Respondents expressed increased awareness of barriers/benefits of telemedicine (2.8 vs 4.7, P<.001) and improved leadership commitment (2.6 vs 4.4, P<.001). The weekly average number of telemedicine visits per respondent increased significantly after protocol implementation (6.5 vs 25.6, P=.002). With support of facility leadership, interdisciplinary team members and engagement of key stakeholders, a telemedicine protocol was implemented in a single, high-volume, post-acute care skilled nursing facility during the COVID-19 pandemic, allowing patients to receive needed care.

Chronic conditions patient's perception of post-COVID-19 pandemic teleconsulting continuation in primary care clinics: a qualitative descriptive study.

OBJECTIVES: The COVID-19 pandemic has led to the prioritisation of teleconsultation instead of face-to-face encounters. However, teleconsultation revealed some shortcomings and undesirable effects that may counterbalance benefits. This study aims to explore the perspective of patients with chronic diseases on teleconsultation in primary care. This article also proposes recommendations to provide patient-oriented and appropriate teleconsultations. DESIGN: We conducted a qualitative descriptive study that explored the patients' perception regarding teleconsultation services and the following themes: access, perceived benefits and disadvantages, interprofessional collaboration, patient-centred approach, specific competencies of professionals, and patient's global needs and preferences. SETTING: Six primary care clinics in three regions of Quebec. PARTICIPANTS: 39 patients were interviewed by telephone through semistructured qualitative interviews. RESULTS: Patients want to maintain teleconsultation for the postpandemic period as long as their recommendations are followed: be able to choose to come to the clinic if they wish to, feel that their individual and environmental characteristics are considered, feel involved in the choice of the modality of each consultation, feel that interprofessional collaboration and patient-centred approach are promoted, and to maintain the professionalism, which must not be lessened despite the remote context. CONCLUSION: Patients mainly expressed high satisfaction with teleconsultation. However, several issues must be addressed. Patients do and should contribute to the implementation of teleconsultation in primary care. They wish to be frequently consulted about their preferred consultation modality, which may change over time. The patient perspective must, therefore, be part of the balanced implementation of optimal teleconsultation that is currently taking place.

Interventions to Improve Trainers' Learning and Behaviors for Educating Health Care Professionals Using Train-the-Trainer Method: A Systematic Review and Meta-analysis.

INTRODUCTION: Train-the-trainer (TTT) programs are frequently used to facilitate knowledge dissemination. However, little is known about the effectiveness of these programs. Therefore, we sought to assess the impact of TTT programs on learning and behavior of trainers for educating health and social professionals (trainees). METHODS: Guided by the Cochrane Effective Practice and Organisation of Care, we conducted a systematic review. We searched 12 databases until April 2018 and extracted data according to the Population, Intervention, Comparison, Outcome model. Population was defined as trainers delivering training program to health care professionals, and the intervention consists in any organized activity provided by a trainer. There were no restrictive comparators, and outcomes were knowledge, attitude, skill, confidence, commitment, and behavior of trainers. We estimated the pooled effect size and its 95% confidence interval using a random-effect model. We performed a narrative synthesis when meta-analysis was not possible. RESULTS: Of 11,202 potentially eligible references, we identified 16 unique studies. Studies were mostly controlled before-and-after studies and covered a unique training intervention. Targeted trainers were mostly nurses (n = 10) and physicians (n = 5). The most frequent measured outcome was knowledge (n = 12). TTT programs demonstrated significant effect on knowledge (Standardized mean deviation = 0.58; 95% CI = 0.11-1.06; I2 = 90%; P < .01; 10 studies). No studies measured trainers' ability to deliver the training program. DISCUSSION: TTT programs may improve the knowledge of trainers. However, the heterogeneity and small number of studies hamper our ability to draw conclusions that are more robust.

Calcium plus vitamin D supplementation and the risk of fractures.

BACKGROUND: The efficacy of calcium with vitamin D supplementation for preventing hip and other fractures in healthy postmenopausal women remains equivocal. METHODS: We recruited 36,282 postmenopausal women, 50 to 79 years of age, who were already enrolled in a Women's Health Initiative (WHI) clinical trial. We randomly assigned participants to receive 1000 mg of elemental [corrected] calcium as calcium carbonate with 400 IU of vitamin D3 daily or placebo. Fractures were ascertained for an average follow-up period of 7.0 years. Bone density was measured at three WHI centers. RESULTS: Hip bone density was 1.06 percent higher in the calcium plus vitamin D group than in the placebo group (P<0.01). Intention-to-treat analysis indicated that participants receiving calcium plus vitamin D supplementation had a hazard ratio of 0.88 for hip fracture (95 percent confidence interval, 0.72 to 1.08), 0.90 for clinical spine fracture (0.74 to 1.10), and 0.96 for total fractures (0.91 to 1.02). The risk of renal calculi increased with calcium plus vitamin D (hazard ratio, 1.17; 95 percent confidence interval, 1.02 to 1.34). Censoring data from women when they ceased to adhere to the study medication reduced the hazard ratio for hip fracture to 0.71 (95 percent confidence interval, 0.52 to 0.97). Effects did not vary significantly according to prerandomization serum vitamin D levels. CONCLUSIONS: Among healthy postmenopausal women, calcium with vitamin D supplementation resulted in a small but significant improvement in hip bone density, did not significantly reduce hip fracture, and increased the risk of kidney stones.

Assessment of pain in older Asian Americans with cancer.

This cross-sectional study focused on pain assessment in a group of older Asian Americans with cancer. Thirty-six participants and their primary nurses were interviewed, and pain intensity was measured using 3 different scales: the Numeric pain intensity 0-10 scale, the Faces expression scale, and Visual analog scale (VAS). Overall, 56% of participants reported pain. Younger age (65-75 years old) was significantly associated with higher pain intensity (p < 0.05). High correlation was found between the participants' and their nurses' pain intensity ratings (r = 0.69, p < 0.0001). High correlation was also found among different pain intensity scales, with a Spearman correlation coefficient ranging from 0.89 to 0.96 (p < 0.0001), suggesting that they are reliable measures in this population.

Cardiovascular risk in women with non-specific chest pain (from the Women's Health Initiative Hormone Trials).

Women discharged with diagnoses of nonspecific chest pain (NSCP) may be at increased risk for subsequent coronary artery disease (CAD) events. The influence of hormone therapy on NSCP is unknown. The Women's Health Initiative (WHI) enrolled postmenopausal women aged 50 to 79 years. The duration of follow-up was 7.1 years in the WHI Estrogen-Alone trial (E-Alone) and 5.6 years in the WHI Estrogen Plus Progestin trial (E+P). After excluding women with previous cardiovascular disease, 9,427 women in E-Alone and 15,105 women in E+P were included in this analysis. NSCP, defined as having a primary hospital discharge diagnosis of NSCP by International Classification of Diseases, Ninth Revision, code, was reported in 322 women in E-Alone and 249 in E+P. Risks for subsequent CAD events were estimated using intent-to-treat Cox proportional-hazards models stratified by clinic and adjusted for age and other risk factors. In the fully adjusted models of the combined trials, women with NSCP had a twofold greater risk for subsequent nonfatal CAD events, including nonfatal myocardial infarction (2.3% vs 1.7%, hazard ratio [HR] 2.10, 95% confidence interval [CI] 1.11 to 3.98), revascularization (3.5% vs 2.6%, HR 1.99, 95% CI 1.20 to 3.30), and hospitalized angina (3.7% vs 2.3%, HR 2.39, 95% CI 1.46 to 3.92). Hormone therapy did not appear to have a significant effect on either the incidence of NSCP hospitalizations (E-Alone: HR 1.04, 95% CI 0.81 to 1.32; E+P: HR 0.78, 95% CI 0.59 to 1.02) or the risk for a subsequent CAD event. In conclusion, a hospitalization for NSCP doubles the risk for a subsequent CAD event in postmenopausal women over the next 5 to 7 years and identifies them as candidates for aggressive risk factor treatment.

Describing Hawai'i's nursing home physicians: the results of a survey.

INTRODUCTION: Despite a growing need for physicians providing care to nursing home patients, the characteristics of physicians providing such care are not well described. METHODS: A survey was sent to adult primary care physicians in Hawai'i; respondents' demographic data were obtained. Associations between physician characteristics, level of nursing home experience, and island of practice were analyzed using chi square and multivariate logistic regression models. RESULTS: Of 806 physicians, 388 (48%) returned surveys. Controlling for years of experience and other demographic factors, having nursing home experience was associated with physician age (40 years and over compared with under 40 years; OR 3.5, 95% Confidence Interval (CI) 1.4-8.5), Family Medicine specialty (compared with Internal Medicine, General Practice or Other; OR 4.0, 95% CI 1.4-11.4), private practice type (compared with employed, other, and trainee physicians; OR 2.3, 95% CI 1. 1-4.6), and practice location (neighbor islands compared with Oahu, OR 4.5, 95% CI 1.1-17.8). Physicians practicing on the neighbor islands were more likely to be aged 40 years and older (OR 3.9, 95% CI 1.4-10.3), and white (ethnicity compared with all other ethnicities, OR 4.1, 95% CI 2.1-7.7). CONCLUSION: The association of higher physician age with both nursing home experience and neighbor island practice has important implications for the training of physicians to provide nursing home care in Hawai'i.

Elderly women diagnosed with nonspecific chest pain may be at increased cardiovascular risk.

BACKGROUND: Women are more likely than men to have nonspecific chest pain (NSCP) symptoms. The long-term outcomes in women discharged with a diagnosis of NSCP are unknown. METHODS: The Women's Health Initiative Observational Study enrolled postmenopausal women aged 50-79 years. After excluding those with prior cardiovascular disease (CVD), 83,622 women were studied. NSCP cases were defined as having an initial primary hospital discharge diagnosis of NSCP (ICD-9 codes 786.50, 786.51, 786.59) without a prior diagnosis of coronary heart disease (CHD). Risks of subsequent CHD events were estimated from Cox proportional hazard ratio (HR) models stratified by clinic and adjusted for baseline age, cardiovascular risk factors, and hormone use. RESULTS: Over an average of 8 years of follow-up, 11% (230 of 2,092) of women with NSCP experienced a cardiovascular event compared with 9.5% (7,724 of 81,530) who did not. Compared with women without a hospitalization for NSCP during follow-up, those with NSCP had a greater than 2-fold higher risk of a subsequent hospitalization for clinically diagnosed angina (HR 2.18, 95% CI 1.66-2.86) and at least a 1.5-fold higher risk of nonfatal myocardial infarction (MI) (HR 1.59, 1.10-2.31), revascularization (HR 1.67, 1.28-2.20), and congestive heart failure (HR 1.75, 1.27-2.41). Women with NSCP who subsequently experienced a CHD event were more likely to be over age 65 or to have cardiovascular risk factors. CONCLUSIONS: Older women discharged with a diagnosis of NSCP may be at increased risk of CHD morbidity. Further research is needed to replicate these findings in other populations.

Utility of the Informant Questionnaire on Cognitive Decline in the Elderly (IQCODE) for dementia in a Japanese-American population.

Ethnic diversity among older patients in Hawai'i is common; yet few data exist concerning the applicability of cognitive testing instruments in non-Caucasian populations. This project aimed to determine the specificity and sensitivity of the IQCODE for the detection of cognitive impairment in a Japanese-American population. Results confirm that the IQCODE is a valuable tool for primary care physicians to detect impairment in this population.

Knowledge and attitudes about geriatrics of medical students, internal medicine residents, and geriatric medicine fellows.

OBJECTIVES: To evaluate the attitudes and knowledge of medical students (MS1-3), internal medicine residents (postgraduate years 1 to 3 (PGY1-3)), and geriatric medicine fellows about elderly patients before implementation of a new geriatrics curriculum. DESIGN: Cross-sectional study. SETTING: An academic medical center. PARTICIPANTS: Two hundred eleven people participated: 54 MS1, 52 MS2, 50 MS3, 20 PGY1, 12 PGY2, 12 PGY3, and 11 geriatric medicine fellows. MEASUREMENTS: Each participant completed a questionnaire, including a 16-item geriatrics attitude scale, and a 23-item knowledge test (both revised versions of the University of California at Los Angeles (UCLA) Geriatrics Survey). Pearson correlation coefficients and t tests were used for statistical analyses. RESULTS: Both surveys demonstrated high internal consistency (alpha=0.70 and 0.71, respectively). Knowledge test scores increased with advancing level of training. MS1 and MS2 scored significantly lower and fellows scored significantly higher than others. PGY3 scored significantly higher than PGY1 on the knowledge test. All groups demonstrated positive attitudes toward geriatric patients (score>3.5). MS1 and fellows had significantly more favorable attitudes scores than more advanced students and residents. CONCLUSION: The results suggest that the UCLA Attitudes Scale and Knowledge Test can be used reliably to assess attitudes and knowledge level across all levels of medical education and training. The information from this study will be used to implement a more structured and comprehensive geriatrics curriculum across all trainee levels to improve attitudes and knowledge in the care of the geriatric patient.

The American Diabetes Association and World Health Organization classifications for diabetes: their impact on diabetes prevalence and total and cardiovascular disease mortality in elderly Japanese-American men.

OBJECTIVE: To compare the prevalence of diabetes according to the American Diabetes Association (ADA) and World Health Organization (WHO) classifications in a sample of elderly Japanese-American men; to examine the association with total and cardiovascular mortality by diabetes status using both classifications; and to determine whether the fasting or 2-h glucose measurement is a stronger predictor of adverse outcomes. RESEARCH DESIGN AND METHODS: Examinations given from 1991 to 1993 in the Honolulu Heart Program were used as baseline for these analyses. Subjects were 71-93 years of age at that time and were followed for total and cardiovascular disease mortality for up to 7 years. RESULTS: A total of approximately 66% of individuals who had diabetes by WHO criteria were missed when the ADA definition was used. The relative risks of total and cardiovascular mortality for those with versus those without diabetes were similar for both definitions; however, when fasting and postload glucose measures were analyzed as continuous variables, the 2-h measurement was a superior predictor and was independent of fasting glucose. In contrast, fasting glucose was not an independent predictor of these outcomes in the presence of the 2-h measurement. CONCLUSIONS: The prevalence of glucose metabolism abnormalities was very high among elderly Japanese-American men. The WHO classification was superior to the ADA classification in identification of subjects at high risk for adverse outcomes. Therefore, we conclude that the 2-h glucose measurement is valuable and should be retained in epidemiologic studies.

Plantation work and risk of Parkinson disease in a population-based longitudinal study.

CONTEXT: Parkinson disease (PD) has an unknown cause; however, convincing evidence is emerging that indicates pesticides can selectively injure the dopaminergic system in laboratory animals. Retrospective studies in humans demonstrate a link between exposure to agricultural lifestyle factors and PD. OBJECTIVE: To determine whether working on a plantation in Hawaii and exposure to pesticides are associated with an increased risk of PD decades later. DESIGN AND SETTING: Prospective cohort study based on the island of Oahu, Hawaii, with 30 years of follow-up. Years of work on a plantation were assessed by questionnaire at study enrollment in 1965. Self-reported information on pesticide exposure was collected at a separate examination 6 years later. PARTICIPANTS: Participants were 7986 Japanese American men born between 1900 and 1919 who were enrolled in the longitudinal Honolulu Heart Program. MAIN OUTCOME MEASURES: Incident PD was determined by medical record review or by an examination conducted by a study neurologist at a later date. RESULTS: During follow-up, 116 men developed PD. Age-adjusted incidence increased significantly among men who worked more than 10 years on a plantation. The relative risk of PD was 1.0 (95% confidence interval, 0.6-1.6), 1.7 (95% confidence interval, 0.8-3.7), and 1.9 (95% confidence interval, 1.0-3.5) for men who worked on a plantation 1 to 10 years, 11 to 20 years, and more than 20 years compared with men who never did plantation work (P =.006, test for trend). Age-adjusted incidence of PD was higher in men exposed to pesticides than in men not exposed to pesticides although this was not statistically significant (P =.10, test for trend). CONCLUSION: These longitudinal observations regarding plantation work in Hawaii support case-control studies suggesting that exposure to pesticides increases the risk of PD.

Tetanus immunity in long-term care facilities.

OBJECTIVES: To investigate the correlates of tetanus immunity in the elderly residing in a long-term care facility in Hawaii. DESIGN: Cross-sectional. SETTING: A nursing home in Honolulu, Hawaii. PARTICIPANTS: Sixty subjects aged 65 and older: 30 men and 30 women. MEASUREMENTS: The interview included demographic information, immunization history, military service information, and other potential risk factors for tetanus. Serum tetanus antibody titers were measured. RESULTS: The data showed that 76.7% (46/60) had adequate tetanus titers. This is in stark contrast to previous studies, which have reported immunity rates of 27% to 46% in similar populations. There were significant associations between immunity and prior history of military service. There were no significant associations between immunity and past history of immunization, education, socioeconomic status, or sex. CONCLUSION: History of immunization from patients, families, or medical charts may be unreliable indicators of tetanus immunity. Recognizing patterns of and barriers to immunization could have important consequences for public health policy in long-term care institutions.

Self-reported driving, cognitive status, and physician awareness of cognitive impairment.

OBJECTIVES: To assess self-reported driving rates in older people and correlate these data with cognitive status and physician recognition of cognitive impairment. DESIGN: Cross-sectional study. SETTING: A multiphysician private practice clinic in a primarily Asian-American community of Honolulu, Hawaii. PARTICIPANTS: Two hundred ninety-seven ambulatory patients aged 65 and older. MEASUREMENTS: Cognitive function was assessed by physician interview using the Cognitive Abilities Screening Instrument (CASI) and proxy informant data. Subjects' self-reported driving status. Outpatient medical records were reviewed. RESULTS: Sixty percent of the studied population reported that they currently drove. This rate decreased from 73.3% (148/202) for subjects with good CASI performance (CASI 282) to 37.5% (21/56) for subjects with intermediate CASI performance (CASI 74-81.9) and further to 23.7% (9/38)for subjects with poor CASI performance (CASI <74). Further analysis of drivers with intermediate and poor CASI performance scores revealed that almost none of their physicians recognized that these drivers had cognitive problems(4.8% (1/21) of drivers with intermediate CASI performance and 11.1% (1/9) of drivers with poor CASI performance). CONCLUSION: In this convenience sample of older drivers, driving rates dropped precipitously with poorer performance on cognitive tests, yet a significant percentage of individuals with intermediate or poor cognitive test performance reported that they currently drove. This poor performance was often unrecognized by their physicians. Low recognition rates could affect physicians' interventions to curb unsafe driving.

Prospective association between low and high total and low-density lipoprotein cholesterol and coronary heart disease in elderly men.

OBJECTIVES: To examine the relationship between total cholesterol (TC) and low-density lipoprotein cholesterol (LDL-C) and the incidence of coronary heart disease (CHD) in elderly men. DESIGN: Prospective. SETTING: Population based. PARTICIPANTS: A sample of 2,424, Japanese-American men aged 71 to 93 was used. MEASUREMENTS: Six years of data on incident fatal plus nonfatal CHD were examined. RESULTS: Analysis revealed a significant U-shaped relationship between age-adjusted CHD rates and both TC and LDL-C. The ranges of TC and LDL-C with the lowest risk of CHD were 200 to 219 mg/dL and 120 to 139 mg/dL, respectively. As cholesterol concentrations declined and increased beyond these ranges, the risk of CHD increased. These U-shaped relationships remained significant after adjusting for age and other risk factors. CONCLUSION: The U-shaped associations between TC and LDL-C and CHD imply a complex relationship between lipids and CHD in late life. The results indicate that elevated lipid levels should continue to be treated in healthy elderly individuals, as they are in those who are younger, although pharmacologically lowering lipids to excessively low levels in the elderly may warrant further study, as does the contribution of subclinical frailty to the relationship of lipids to CHD risk.
