Risk Assessment and Prevention of Falls in Older Community-Dwelling Adults: A Review.

Importance: Falls are reported by more than 14 million US adults aged 65 years or older annually and can result in substantial morbidity, mortality, and health care expenditures. Observations: Falls result from age-related physiologic changes compounded by multiple intrinsic and extrinsic risk factors. Major modifiable risk factors among community-dwelling older adults include gait and balance disorders, orthostatic hypotension, sensory impairment, medications, and environmental hazards. Guidelines recommend that individuals who report a fall in the prior year, have concerns about falling, or have gait speed less than 0.8 to 1 m/s should receive fall prevention interventions. In a meta-analysis of 59 randomized clinical trials (RCTs) in average-risk to high-risk populations, exercise interventions to reduce falls were associated with 655 falls per 1000 patient-years in intervention groups vs 850 falls per 1000 patient-years in nonexercise control groups (rate ratio [RR] for falls, 0.77; 95% CI, 0.71-0.83; risk ratio for number of people who fall, 0.85; 95% CI, 0.81-0.89; risk difference, 7.2%; 95% CI, 5.2%-9.1%), with most trials assessing balance and functional exercises. In a meta-analysis of 43 RCTs of interventions that systematically assessed and addressed multiple risk factors among individuals at high risk, multifactorial interventions were associated with 1784 falls per 1000 patient-years in intervention groups vs 2317 falls per 1000 patient-years in control groups (RR, 0.77; 95% CI, 0.67-0.87) without a significant difference in the number of individuals who fell. Other interventions associated with decreased falls in meta-analysis of RCTs and quasi-randomized trials include surgery to remove cataracts (8 studies with 1834 patients; risk ratio [RR], 0.68; 95% CI, 0.48-0.96), multicomponent podiatry interventions (3 studies with 1358 patients; RR, 0.77; 95% CI, 0.61-0.99), and environmental modifications for individuals at high risk (12 studies with 5293 patients; RR, 0.74; 95% CI, 0.61-0.91). Meta-analysis of RCTs of programs to stop medications associated with falls have not found a significant reduction, although deprescribing is a component of many successful multifactorial interventions. Conclusions and Relevance: More than 25% of older adults fall each year, and falls are the leading cause of injury-related death in persons aged 65 years or older. Functional exercises to improve leg strength and balance are recommended for fall prevention in average-risk to high-risk populations. Multifactorial risk reduction based on a systematic clinical assessment for modifiable risk factors may reduce fall rates among those at high risk.

Aging is not an Illness: Exploring Geriatricians' Resistance to Serious Illness Conversations.

CONTEXT: Serious illness conversations help clinicians align medical decisions with patients' goals, values, and priorities and are considered an essential component of shared decision-making. Yet geriatricians at our institution have expressed reluctance about the serious illness care program. OBJECTIVES: We sought to explore geriatricians' perspectives on serious illness conversations. METHODS: We conducted focus groups with interprofessional stakeholders in geriatrics. RESULTS: Three key themes emerged that help explain the reluctance of clinicians caring for older patients to have or document serious illness conversations: 1) aging in itself is not a serious illness; 2) geriatricians often focus on positive adaptation and social determinants of health and in this context, the label of "serious illness conversations" is perceived as limiting; and 3) because aging is not synonymous with illness, important goals-of-care conversations are not necessarily documented as serious illness conversations until an acute illness presents itself. CONCLUSION: As institutions work to create system-wide processes for documenting conversations about patients' goals and values, the unique communication preferences of older patients and geriatricians should be specifically considered.

Cross-Sectional Assessment of the Association of Eosinophilia with Intestinal Parasitic Infection in U.S.-Bound Refugees in Thailand: Prevalent, Age Dependent, but of Limited Clinical Utility.

The most common causes of eosinophilia globally are helminth parasites. Refugees from high endemic areas are at increased risk of infection compared with the general U.S. population. It is widely accepted that eosinophilia is a good marker for helminth infection in this population, yet its absence has little predictive value for excluding infection. During an enhanced premigration health program, the CDC offered voluntary testing and management of intestinal parasites, among other conditions, to U.S.-bound refugees in Thailand. Stool specimens were tested for Ascaris lumbricoides, Strongyloides stercoralis, Trichuris trichiura, hookworms, Giardia lamblia, Cryptosporidium spp., and Entamoeba histolytica using quantitative polymerase chain reaction. Complete blood counts were performed to identify eosinophilia. Predictive values of eosinophilia for parasitic infections were calculated within nematode groups. Between July 9, 2012 and November 29, 2013, 2,004 participants were enrolled. About 73% were infected with at least one parasite. The overall median eosinophil count was 483 cells/µL (interquartile range [IQR] = 235-876 cells/µL). Compared with participants who did not test positive for any infection, higher eosinophil counts were observed in those infected with A. lumbricoides (RR = 1.3, 95% CI = 1.1-1.4), S. stercoralis (RR = 1.8, 95% CI = 1.4-2.4), Necator americanus (RR = 1.2, 95% CI = 1.1-1.4), and Ancylostoma ceylanicum (RR = 1.8, 95% CI = 1.5-2.2). Eosinophil counts were higher in younger participants (2-4 years versus 65+ years: RR = 4.2, 95% CI = 2.5-6.9), and lower in female participants (RR = 0.9, 95% CI = 0.8-0.9). Sensitivities ranged from 51% to 73%, specificities from 48% to 65%, and predictive values from 4% to 98%. The predictive value of eosinophilia is poor for the most common parasitic infections, and it should not be used alone for screening refugees.

Discontinuation of beta-blockers among nursing home residents at end of life.

BACKGROUND: Given limited life expectancy of nursing home (NH) residents, harms of continuing beta-blockers (BBs) may outweigh clinical benefits. Our objective was to describe beta-blocker discontinuation for NH residents during the last year of life, and identify characteristics associated with earlier discontinuation. METHODS: This was a retrospective cohort study that included all long-stay residents in fee-for-service Medicare who died in 2016 and were prescribed oral BBs 1 year before death. Beta-blocker discontinuation was defined as a gap in medication on hand for ≥45 days per Medicare Part D claims, measured from the last date drug was on hand. Comorbidities were obtained from Chronic Condition Warehouse, and other characteristics from the Minimum Data Set. Kaplan-Meier curves were used to describe time to first discontinuation. Findings were stratified by cardiac diagnoses, perceived life expectancy of <6 months, or elevated mortality index. RESULTS: Eighty-eight thousand two hundred and eighty-four residents were prescribed ≥1 daily BB 12 months before death. Mean age was 84.1 years and 69.2% were female. Of these, 60,573 residents (68.6%) remained on a BB in the last 45 days of life, and 57,880 residents (65.6%) had ≥1 cardiac diagnosis. Only 5239 residents (5.9%) had elevated mortality index, whereas 16,798 residents (19.0%) had perceived poor prognosis. In the last year of life, there was no difference in beta-blocker discontinuation pattern between residents with and without cardiac diagnoses. Residents with perceived poor prognosis and elevated mortality index discontinued BBs earlier. For example, mean time until discontinuation among residents with poor perceived prognosis was 245 versus 279 days in residents without such prognosis (p < 0.0001). CONCLUSIONS: BBs are commonly prescribed to NH residents in the final year of life. Overall, discontinuation occurs earlier in residents for whom clinicians perceive limited life expectancy, suggesting that improved prognostication may offer an important opportunity to reduce polypharmacy toward end of life.

People with Parkinson's disease are more willing to do additional exercise if the exercise program has specific attributes: a discrete choice experiment.

QUESTION: What specific attributes of exercise programs influence the preferences of people with Parkinson's disease for additional exercise compared with their current practice? What trade-offs are participants willing to make between exercise program attributes? DESIGN: Discrete choice experiment. PARTICIPANTS: Five hundred and forty people with Parkinson's disease. INTERVENTION: Participants decided whether they would adopt a hypothetical program in addition to their current exercise routine. OUTCOME MEASURES: Exercise program attributes included: type, number of sessions/week, location, travel time/session, delivery mode, supervisor's expertise, extent of supervision, benefits for physical and psychological function and out-of-pocket cost/session. RESULTS: Participants preferred additional exercise when programs: provided physical (OR 1.85, 95% CI 1.61 to 2.13) or psychological (OR 1.45, 95% CI 1.26 to 1.67) benefit, involved less travel time (ORs 1.50 to 2.02) and were supervised by qualified professionals with Parkinson's disease expertise (ORs 1.51 to 1.91). Participants were most willing to add multimodal exercise to their exercise routine (ORs 2.01 to 2.19). Participants were less likely to prefer higher cost programs (OR 0.65, 95% CI 0.60 to 0.71, per AU$10 cost increase) or group sessions compared to individual sessions (OR 0.72, 95% CI 0.54 to 0.96). Men preferred adding strengthening exercises (OR 2.00, 95% CI 1.23 to 3.26) and women had a preference against adding aerobic exercise (OR 0.33, 95% CI 0.15 to 0.73). Participants not currently exercising were more likely to prefer adding exercise compared with those already exercising 300 minutes weekly (OR 1.74, 95% CI 1.15 to 2.63). CONCLUSION: People with Parkinson's disease were more willing to participate in exercise programs that cost less, involve less travel, provide physical or psychological benefits and are supervised by qualified professionals. To enable more people with Parkinson's disease to exercise, health services should provide programs addressing these factors and account for sex differences.

Health screening results of Cubans settling in Texas, USA, 2010-2015: A cross-sectional analysis.

BACKGROUND: Protecting the health of refugees and other migrant populations in the United States is key to ensuring successful resettlement. Therefore, to identify and address health concerns early, the US Centers for Disease Control and Prevention (CDC) recommends a domestic medical examination (screening for infectious and noninfectious diseases/conditions) shortly after arrival in the US. However, because refugee/migrant populations often have differing health patterns from one another and the US population, the collection and analysis of health information is key to developing population-specific clinical guidelines to guide the care of resettled individuals. Yet little is known regarding the health status of Cubans resettling in the US. Among the tens of thousands of Cuban migrants who have resettled in the US, some applied as refugees in Cuba, some applied for parole (a term used to indicate temporary US admission status for urgent humanitarian reasons or reasons of public benefit under US immigration law) in Cuba, and others applied for parole status after crossing the border. These groups were eligible for US government benefits to help them resettle, including a domestic medical examination. We reviewed health differences found in these examinations of those who were determined to be refugees or parolees in Cuba and those who were given parole status after arrival. METHODS AND FINDINGS: We conducted a retrospective cross-sectional analysis of the Texas Department of State Health Services database. Cubans who arrived from 2010 to 2015 and received a domestic medical examination in Texas were included. Those granted refugee/parolee status in Cuba were listed in federal databases for US-bound refugees/parolees; those who were paroled after arrival were not listed. Overall, 2,189 (20%) obtained either refugee or parolee status in Cuba, and 8,709 (80%) received parolee status after arrival. Approximately 62% of those who received parolee status after arrival at the border were male, compared with 49% of those who obtained prior refugee/parolee status in Cuba. Approximately one-half (45%) of those paroled after arrival were 19-34 years old (versus 26% among those who obtained refugee/parolee status in Cuba). Separate models were created for each screening indicator as the outcome, with entry route as the main exposure variable. Crude and adjusted prevalence ratios were estimated using PROC GENMOD procedures in SAS 9.4. Individuals paroled after arrival were less likely to screen positive for parasitic infections (9.6% versus 12.2%; adjusted prevalence ratio: 0.79, 0.71-0.88) and elevated blood lead levels (children ≤16 years old, 5.2% versus 12.3%; adjusted prevalence ratio: 0.42, 0.28-0.63). Limitations include potential disease misclassification, missing clinical information, and cross-sectional nature. CONCLUSIONS: Within-country variations in health status are often not examined in refugee populations, yet they are critical to understand granular health trends. Results suggests that the health profiles of Cuban Americans in Texas differed by entry route. This information could assist in developing targeted screenings and health interventions.

Vaccine delivery to newly arrived refugees and estimated costs in selected U.S. clinics, 2015.

BACKGROUND: Newly arrived refugees are offered vaccinations during domestic medical examinations. Vaccination practices and costs for refugees have not been described with recent implementation of the overseas Vaccination Program for U.S.-bound Refugees (VPR). We describe refugee vaccination during the domestic medical examination and the estimated vaccination costs from the US government perspective in selected U.S. clinics. METHODS: Site-specific vaccination processes and costs were collected from 16 clinics by refugee health partners in three states and one private academic institution. Vaccination costs were estimated from the U.S. Vaccines for Children Program and Medicaid reimbursement rates during fiscal year 2015. RESULTS: All clinics reviewed overseas vaccination records before vaccinating, but all records were not transferred into state immunization systems. Average vaccination costs per refugee varied from $120 to $211 by site. The total average cost of domestic vaccination was 15% less among refugees arriving from VPR- vs. nonVPR-participating countries during a single domestic visit. CONCLUSION: Our findings indicate that immunization practices and costs vary between clinics, and that clinics adapted their vaccination practices to accommodate VPR doses, yielding potential cost savings.

Examining the Impact of a Web-Based Intervention to Promote Patient Activation in Chemotherapy-Induced Peripheral Neuropathy Assessment and Management.

Lack of activation in self-care can compromise a patient's ability to monitor and manage cancer treatment-related side effects, such as chemotherapy-induced peripheral neuropathy (CIPN). The web-based Carevive® Care Planning System (CPS) was developed to promote evidence-based symptom assessment and treatment by enhancing patients' involvement in their own care. The purpose of this single-arm, pre-test/post-test, prospective study was to examine whether the CPS can promote patient activation in CIPN symptom assessment and management. Seventy-five women with breast cancer receiving neurotoxic chemotherapy were recruited from a Comprehensive Cancer Center. Using standardized neuropathy measures embedded within the CPS, patients reported their CIPN symptoms over three consecutive clinical visits and completed the Patient Activation Measure (PAM) at the first and third visits. Mean changes in PAM scores between visits were compared using repeated measure analysis of covariance, adjusting for age. At baseline, patients were diagnosed with cancer within the past year (94.7%), highly activated (85% Level III/IV), and had a mean age of 51.3. PAM scores improved significantly from 67.15 (SD = 13.5; range = 47-100) at visit one to 69.29 (SD = 16.18; range = 47-100) (p = 0.02) (n = 62) at visit three. However, patients perceived the CPS to be of minimal value because it solely focused on CIPN and, for many, CIPN was not severe enough to motivate them to seek out symptom management information. Further research is needed to assess the utility of the CPS in promoting activation in the assessment and management of varying cancer treatment-related symptoms.

Changes in health promotion practice in hospitals across England: the National Health Promotion in Hospital Audit 2009 and 2011.

BACKGROUND: There is increasing focus on hospitals to provide health promotion (HP) to patients who smoke, misuse alcohol, are obese or physically inactive, yet there is little published literature on assessment and HP in English hospitals. METHODS: Thirty hospitals participated in national audits, both in 2009 and 2011, to assess HP in hospitalized patients. Random samples of 100 patients were selected per hospital per year. RESULTS: Between the 2009 and 2011 audit, assessment rates increased for smoking (82 versus 86%; P < 0.001) and obesity (38 versus 53%; P < 0.001), alcohol assessments remained similar (71 versus 73%; P = 0.123) and physical activity assessments decreased (34 versus 28%; P < 0.001). Provision of HP was similar in both audits for smoking (22 versus 26%; P = 0.17), alcohol misuse (47 versus 44%; P = 0.12) and physical inactivity (43 versus 44%; P = 0.865), but fell for obesity (26 versus 14%; P < 0.001). Few hospitals met the standards for assessment and HP for each risk factor. CONCLUSIONS: Whilst patients are being assessed for most lifestyle risk factors, and despite an increased policy focus, there remains little evidence of HP practice in English hospitals. There is potential for health gain across England that could be exploited through wider provision of HP for hospitalized patients.

Volumetric assessment of cleft lip and palate defects using cone beam computed tomography.

A possible avenue to improve the clinical success of bone graft procedures in cleft lip and palate cases is to predetermine the bone donor site and the volume of graft material required for the recipient site. This study utilized cone beam computed tomography to generate three-dimensional reconstructions and volumetrically assess unilateral cleft lip and palate defects. Access to this information can assist in determining an optimal donor site for secondary alveolar bone grafting.

Tissue-like phantoms for near-infrared fluorescence imaging system assessment and the training of surgeons.

We demonstrate how to construct calibrated, stable, and inexpensive tissue-like phantoms for near-IR (NIR) fluorescence imaging applications. The bulk phantom material is composed of gelatin, intralipid, hemoglobin, and indocyanine green (ICG). Absorbance, scatter, background fluorescence, and texture can be tuned as desired. NIR fluorescent inclusions are comprised of ICG-labeled polystyrene divinylbenzene beads and Pam78-labeled hydroxyapatite crystals. The former mimic tumor masses of controllable size and contrast agent concentration, and the latter mimic microcalcifications in breast cancer. NIR-fluorescent inclusions can be positioned precisely in phantoms, with one or more regions having different optical properties, and their position can be verified independently using microcomputed tomography. We demonstrate how these phantoms can be used to calibrate and compare imaging systems, and to train surgeons to operate under NIR fluorescence image guidance.

Realigning economic incentives for depression care at UCSF.

Behavioral health carve-out arrangements create financial disincentives for primary care providers (PCPs) to treat depression. A novel collaboration between a primary care practice, a health insurer, and a managed behavioral health organization (MBHO) allows PCPs to receive reimbursement and schedule longer appointments to care for depressed patients. This article describes the details of the arrangement, and early results of this collaboration. Early results find that financial incentives are critical for implementation, but that time incentives do not appear to motivate PCPs. Sustainability of this model will require participation of multiple primary care practices, health insurers, and MBHOs.
