Fear of Outdoor Falling Among Community-Dwelling Middle-Aged and Older Adults: The Role of Neighborhood Environments.

Background and Objectives: Fear of falling is a substantial barrier to walking and has been associated with increased fall risks. This study examines neighborhood environmental risk factors related to fear of outdoor falling in middle-aged and older adults. Research Design and Methods: A total of 394 participants aged 50 years or older living independently in the community were recruited between 2013 and 2014 from an integrated health care network serving Central Texas. Fear of outdoor falling and perceived neighborhood environmental variables were assessed using self-reported questionnaires. Logistic regression identified perceived neighborhood environmental variables associated with fear of outdoor falling. Results: Sixty-nine (17.9%) of 385 participants reported having a fear of outdoor falling. Compared to those who did not report a fear of outdoor falling, those who reported having a fear of outdoor falling were more likely to be adults aged 65 years or older (odds ratio [OR] = 2.974, 95% confidence interval [CI] = 1.247-7.094), be female (OR = 4.423, 95% CI = 1.830-10.689), have difficulty with walking for a quarter of a mile (OR = 2.761, 95% CI = 1.124-6.782), and have had a fall in the past year (OR = 4.720, 95% CI = 1.472-15.137). Among the neighborhood environmental characteristics examined, low traffic speed on streets (OR = 0.420, 95% CI = 0.188-0.935), drainage ditches (OR = 2.383, 95% CI = 1.136-5.000), and broken sidewalks (OR = 3.800, 95% CI = 1.742-8.288) were associated with the odds of having a fear of outdoor falling. Discussion and Implications: In addition to the individual factors, findings from this study suggest the importance of addressing the environmental risk factors in identifying and reducing fear of outdoor falling among middle-aged and older adults.

Social and environmental predictors of walking among older adults.

BACKGROUND: Regular physical activity (PA) is a major factor in maintaining health in aging populations. This study examines the influences of sociodemographic, health, and environmental characteristics on older adults' walking behaviors, and the role physicians can play in promoting physical activity. METHODS: Online and paper surveys (n = 272) were distributed to community-dwelling older (age ≥ 60) adults from a large integrated healthcare system in two counties in Central Texas. Descriptive statistics were utilized to characterize participant's walking behaviors and places. Multivariate logistic regression was employed to predict being: 1) a frequent walker (i.e., walking at least three times a week); and 2) meeting the Centers for Disease Control and Prevention (CDC) PA recommendation through walking (i.e., walking ≥150 min per week), while considering sociodemographic, health, and environmental factors. RESULTS: Individuals had a median age of 69 years, were of both genders (50.37 % female), and were primarily non-Hispanic White (84.87 %). While the majority (59.55 %) walked at least three times a week, only 27.86 % walked ≥150 min a week. Factors associated with a lower likelihood of being frequent walkers included experiencing poor mental health in the past month (OR = 0.345, 95 % CI = 0.185-0.645) and residing in areas with low or moderate (versus high) perceived neighborhood cohesion (OR = 0.471, 95 % CI = 0.228-0.974), while those in Census Tracts reflecting populations with a lower median age were more likely to report frequent walking behavior (OR = 1.799, 95 % CI = 1.034-3.131). Factors associated with a lower likelihood of meeting the CDC PA recommendation included being 60-69 years (versus 70 years or older) (OR = 0.538, 95 % CI = 0.290-0.997), experiencing poor mental health in the past month (OR = 0.432, 95 % CI = 0.198-0.944), and lacking social support for walking (OR = 0.383, 95 % CI = 0.154-0.957). CONCLUSION: Given the health benefits, PA promotion must be seen as a national responsibility. In particular, physicians have a major role to play in communicating the importance of PA to their older patients and making discussions about strategies for overcoming barriers to walking an integral part of their clinical encounter with these patients.

Impact of chronic disease self-management programs on type 2 diabetes management in primary care.

AIM: To assess the effectiveness of the Chronic Disease Self-Management Program (CDSMP) on glycated hemoglobin A1c (HbA1c) and selected self-reported measures. METHODS: We compared patients who received a diabetes self-care behavioral intervention, the CDSMP developed at the Stanford University, with controls who received usual care on their HbA1c and selected self-reported measures, including diabetes self-care activities, health-related quality of life (HRQOL), pain and fatigue. The subjects were a subset of participants enrolled in a randomized controlled trial that took place at seven regional clinics of a university-affiliated integrated healthcare system of a multi-specialty group practice between January 2009 and June 2011. The primary outcome was change in HbA1c from randomization to 12 mo. Data were analyzed using multilevel statistical models and linear mixed models to provide unbiased estimates of intervention effects. RESULTS: Demographic and baseline clinical characteristics were generally comparable between the two groups. The average baseline HbA1c values in the CDSMP and control groups were 9.4% and 9.2%, respectively. Significant reductions in HbA1c were seen at 12 mo for the two groups, with adjusted changes around 0.6% (P < 0.0001), but the reductions did not differ significantly between the two groups (P = 0.885). Few significant differences were observed in participants' diabetes self-care activities. No significant differences were observed in the participants' HRQOL, pain, or fatigue measures. CONCLUSION: The CDSMP intervention may not lower HbA1c any better than good routine care in an integrated healthcare system. More research is needed to understand the benefits of self-management programs in primary care in different settings and populations.

Behavioral and technological interventions targeting glycemic control in a racially/ethnically diverse population: a randomized controlled trial.

BACKGROUND: Diabetes self-care by patients has been shown to assist in the reduction of disease severity and associated medical costs. We compared the effectiveness of two different diabetes self-care interventions on glycemic control in a racially/ethnically diverse population. We also explored whether reductions in glycated hemoglobin (HbA1c) will be more marked in minority persons. METHODS: We conducted an open-label randomized controlled trial of 376 patients with type 2 diabetes aged ≥18 years and whose last measured HbA1c was ≥7.5% (≥58 mmol/mol). Participants were randomized to: 1) a Chronic Disease Self-Management Program (CDSMP; n = 101); 2) a diabetes self-care software on a personal digital assistant (PDA; n = 81); 3) a combination of interventions (CDSMP + PDA; n = 99); or 4) usual care (control; n = 95). Enrollment occurred January 2009-June 2011 at seven regional clinics of a university-affiliated multi-specialty group practice. The primary outcome was change in HbA1c from randomization to 12 months. Data were analyzed using a multilevel statistical model. RESULTS: Average baseline HbA1c in the CDSMP, PDA, CDSMP + PDA, and control arms were 9.4%, 9.3%, 9.2%, and 9.2%, respectively. HbA1c reductions at 12 months for the groups averaged 1.1%, 0.7%, 1.1%, and 0.7%, respectively and did not differ significantly from baseline based on the model (P = .771). Besides the participants in the PDA group reporting eating more high-fat foods compared to their counterparts (P < .004), no other significant differences were observed in participants' diabetes self-care activities. Exploratory sub-analysis did not reveal any marked reductions in HbA1c for minority persons but rather modest reductions for all racial/ethnic groups. CONCLUSIONS: Although behavioral and technological interventions can result in some modest improvements in glycemic control, these interventions did not fare significantly better than usual care in achieving glycemic control. More research is needed to understand how these interventions can be most effective in clinical practice. The reduction in HbA1c levels found in our control group that received usual care also suggests that good routine care in an integrated healthcare system can lead to better glycemic control.

Electronic health record-based triggers to detect potential delays in cancer diagnosis.

BACKGROUND: Delayed diagnosis of cancer can lead to patient harm, and strategies are needed to proactively and efficiently detect such delays in care. We aimed to develop and evaluate 'trigger' algorithms to electronically flag medical records of patients with potential delays in prostate and colorectal cancer (CRC) diagnosis. METHODS: We mined retrospective data from two large integrated health systems with comprehensive electronic health records (EHR) to iteratively develop triggers. Data mining algorithms identified all patient records with specific demographics and a lack of appropriate and timely follow-up actions on four diagnostic clues that were newly documented in the EHR: abnormal prostate-specific antigen (PSA), positive faecal occult blood test (FOBT), iron-deficiency anaemia (IDA), and haematochezia. Triggers subsequently excluded patients not needing follow-up (eg, terminal illness) or who had already received appropriate and timely care. Each of the four final triggers was applied to a test cohort, and chart reviews of randomly selected records identified by the triggers were used to calculate positive predictive values (PPV). RESULTS: The PSA trigger was applied to records of 292 587 patients seen between 1 January 2009 and 31 December 2009, and the CRC triggers were applied to 291 773 patients seen between 1 March 2009 and 28 February 2010. Overall, 1564 trigger positive patients were identified (426 PSA, 355 FOBT, 610 IDA and 173 haematochezia). Record reviews revealed PPVs of 70.2%, 66.7%, 67.5%, and 58.3% for the PSA, FOBT, IDA and haematochezia triggers, respectively. Use of all four triggers at the study sites could detect an estimated 1048 instances of delayed or missed follow-up of abnormal findings annually and 47 high-grade cancers. CONCLUSIONS: EHR-based triggers can be used successfully to flag patient records lacking follow-up of abnormal clinical findings suspicious for cancer.

Challenges and opportunities for implementing diabetes self-management guidelines.

PURPOSE: The purpose of this article was to examine primary care providers' perceived challenges when implementing evidence-based diabetes self-management guidelines and opportunities for promoting the use of such guidelines in practice. METHODS: We engaged 3 group discussions with 43 key stakeholders representing family physicians, medical directors, and quality assurance leaders in a large, university-affiliated, integrated health care organization in Central Texas. Transcripts from group discussions were summarized using thematic content analysis. RESULTS: Key themes that emerged as challenges of implementing evidence-based diabetes self-management guidelines included lack of easily retrievable electronic patient health information, inadequate coordination with other health care providers when implementing guidelines, conflict between information in the guidelines and physicians' knowledge, and physician compensation by patient load rather than by quality of care. Two main opportunities identified were the use of health coaches or nurses trained in diabetes self-management and active collaboration between practicing providers and key stakeholders in the development and dissemination of guidelines. CONCLUSION: Our study shows a need for involving front-line family physicians and other primary care providers as well as patients in the design and development of best practice guidelines to enhance implementation of diabetes self-management guidelines in primary care settings.

Neighborhood walking among overweight and obese adults: age variations in barriers and motivators.

Walking is a popular form of physical activity that can bring many public health benefits. It can be even more beneficial to those who are currently obese or overweight. However, many barriers discourage people from walking, ranging from lack of motivation to unsafe neighborhood environments, and such barriers vary with age. This study addresses barriers and motivators to walking among overweight and obese adults, and examines their age variations. Particular emphasis was given to modifiable environmental factors as the priority intervention targets. A survey of 161 overweight and obese adults recruited from a large integrated healthcare system in central Texas provided data on walking, demographics, motivators and barriers. Descriptive statistics and correlation analysis were conducted. The respondents had a mean age of 48.4 (20-86), and were predominantly female (80.8%), non-Hispanic White (86.0%), and obese (mean BMI = 32.5). Popular environmental barriers to walking were: bad weather, inadequate lighting, no shade, unattended dogs, disconnected sidewalks, poor walking surfaces, no interesting places to walk nearby, and no benches (74.5-38.5%). Even and smooth walking surfaces and benches were more frequently reported by older adults as motivators. Proximity to recreational facilities was a stronger motivator for younger adults. Two safety related barriers, fear of injury (older adults) and traffic safety concerns (younger adults), also showed significant age differences. Overweight and obese adults experience substantial environmental barriers to walking, but many of them are modifiable. Observed age variations suggest that future interventions may be more effective if tailored to address age-specific barriers.

Identifying opportunities for improved colorectal cancer screening in primary care.

BACKGROUND: Although current recommendations advocate screening persons 50 years of age or older for colorectal cancer (CRC), actual screening practice is highly variable among primary care physicians (PCPs). Knowledge of the factors that influence whether or not screening is offered during a clinic visit is essential to develop effective screening strategies. METHODS: A cross-sectional telephone survey of one in four randomly selected patients aged 50 years or older (n = 400) attending a primary care clinic within an integrated health care system in central Texas was conducted. A survey of all PCPs (n = 32) at the practice sites was also administered. RESULTS: The visit type was an important determinant of whether CRC screening was discussed, with most discussion occurring during visits for physicals (P < 0.0001). This finding was corroborated by the physician survey. Patient age and education were also associated with a higher likelihood of having been offered CRC screening (P = 0.009 and 0.014, respectively). Patient race, gender, primary language, PCP, or clinics attended were not significantly associated with the discussion of CRC screening. CONCLUSIONS: Discussions regarding CRC screening are most likely to occur during preventive care visits. Thus, facilitating preventive visits especially for the elderly represents an opportunity to improve CRC screening rates in primary care practice.

Teaching medical students complementary and alternative medicine using evidence-based principles.

OBJECTIVES: Introducing new ideas such as complementary and alternative medicine (CAM) and evidence-based medicine (EBM) to medical students early in their education may help to nurture their interest. This study evaluated the effectiveness of teaching CAM using EBM principles and assessed changes in student perceived knowledge, attitudes, and skills following a new curriculum on CAM. DESIGN: A before-and-after evaluation using a one-page, anonymous questionnaire. SETTING AND SUBJECTS: All third year students of a state, public medical school in Texas. INTERVENTION: A new curriculum comprising interactive sessions on CAM, EBM, and basic principles of epidemiology and biostatistics. OUTCOME MEASURES: Changes in student-perceived knowledge, attitudes, and skills. RESULTS: Of 67 students, complete data were obtained for 54 (81%). The majority reported that the new instruction in CAM (98%), EBM (96%), biostatistics (91%), and epidemiology (87%) would be of some benefit in their future work. Significant changes were reported in the areas of appraising a clinical trial (p < 0.0001), critiquing the medical literature (p < 0.01), and the appropriateness of integrating EBM and CAM in the medical school curriculum (p < 0.05). There were modest increases in the mean responses on their skill level in reading/understanding the medical literature (3.40-3.52), comfort level in reading the medical literature (3.53-3.67), and preparedness in designing a research study (2.12-2.39) based on a five-point Likert scale, although not statistically significant. CONCLUSIONS: Medical students could be effectively taught CAM using EBM principles. In addition, a short, interactive curriculum on an important topic has a positive impact on medical students' desires to acquire new knowledge. This should be a good motivational message to family medicine educators regarding the contribution to new knowledge such as CAM.
