SARS-CoV-2 control on a large urban college campus without mass testing.

OBJECTIVE: A small percentage of universities and colleges conducted mass SARS-CoV-2 testing. However, universal testing is resource-intensive, strains national testing capacity, and false negative tests can encourage unsafe behaviors. PARTICIPANTS: A large urban university campus. METHODS: Virus control centered on three pillars: mitigation, containment, and communication, with testing of symptomatic and a random subset of asymptomatic students. RESULTS: Random surveillance testing demonstrated a prevalence among asymptomatic students of 0.4% throughout the term. There were two surges in cases that were contained by enhanced mitigation and communication combined with targeted testing. Cumulative cases totaled 445 for the term, most resulting from unsafe undergraduate student behavior and among students living off-campus. A case rate of 232/10,000 undergraduates equaled or surpassed several peer institutions that conducted mass testing. CONCLUSIONS: An emphasis on behavioral mitigation and communication can control virus transmission on a large urban campus combined with a limited and targeted testing strategy.

Association Between Improved Mobility and Distal Health Outcomes.

BACKGROUND: We examined the association between improved mobility and distal health outcomes in older adults using secondary analysis of data from a cluster-randomized controlled group exercise trial. METHODS: Participants were 303 men and women aged ≥65 and older in 32 independent living facilities, senior apartments, and community centers who participated in 12-week group exercise interventions. Included were those who completed ≥1 follow-up phone call regarding outcomes assessment in the following year. Gait speed and 6-minute walk distance (6MWD) were assessed at baseline and immediately after 12-week interventions to determine mobility performance change status. Falls, emergency department (ED) visits, and hospitalizations were assessed monthly for 12 months following the end of interventions via interactive voice response phone calls. Incident rate ratios (IRRs) were calculated to quantify incidence of adverse outcomes with respect to mobility performance change. RESULTS: Each 0.05 m/s increase in gait speed resulted in an 11% reduction in falls (IRR = 0.89; 95% confidence interval [CI], 0.84-0.94; p < .0001); a similar decrease was seen for each 20 m increase in 6MWD (IRR = 0.89; 95% CI, 0.83-0.93; p = .0003). Those who improved gait speed had 61 falls per 1,000 person-months versus 135 in those who had no change/a decline. Those who improved 6MWD had 67 falls per 1,000 person-months versus 110 per 1,000 person-months in those who had no change/a decline. Differences in ED visits and hospitalizations were not statistically significant. CONCLUSION: Improvements in mobility performance are associated with lower incidence of future falls. Given the exploratory nature of the findings, further investigation is warranted.

Improving Patient Reported Outcomes and Preventing Depression and Anxiety in Older Adults With Knee Osteoarthritis: Results of a Sequenced Multiple Assignment Randomized Trial (SMART) Study.

OBJECTIVE: Older adults with knee osteoarthritis (OA) and comorbid subsyndromal depressive symptoms are at elevated risk for incidental major depression or anxiety disorders. Using an indicated prevention paradigm, the authors conducted a sequenced multiple assignment randomized trial (SMART) to: 1) evaluate the effect of cognitive behavioral therapy (CBT) and physical therapy (PT), together with the temporal ordering of these interventions, on patient-reported global impression of change (P-GIC), mood, anxiety, and pain; and 2) compare the strategies' impact on incidence of common psychiatric disorders over 12-months. METHODS: This intervention development trial compared four adaptive strategies delivered in two stages (each up to 8 weeks), contrasted with enhanced usual care (EUC). The strategies were CBT followed by an increased dose of CBT (CBT-CBT), CBT followed by PT (CBT-PT), PT followed by an increased dose of PT (PT-PT), and PT followed by CBT (PT-CBT). Participants (n = 99) were aged 60 years and older and met clinical criteria for knee OA and subthreshold depression. Response was defined as at least "much better" on the P-GIC. Participants were assessed quarterly for 12 months for incidence of psychiatric disorders. RESULTS: Stage 1 response was higher for PT (47.5%) compared to CBT (20.5%). Non-responders receiving an additional dose of the same intervention experienced a response rate of 73%, higher than for switching to a different intervention. All strategies were superior to EUC (5%). Although not powered to detect effects on disorders, neither intervention strategy nor response status affected 12-month incidence of depression and anxiety disorders. CONCLUSION: As response rates were similar for PT-PT and CBT-CBT, it may be dose and not type of these interventions that are necessary for clinical benefit. For non-responders, this finding may guide providers to stay the clinical course for up to 12 weeks before switching. These results support future trials of SMART designs in late-life depression prevention.

Direct Release of Test Results to Patients Increases Patient Engagement and Utilization of Care.

An important focus for meaningful use criteria is to engage patients in their care by allowing them online access to their health information, including test results. There has been little evaluation of such initiatives. Using a mixed methods analysis of electronic health record data, surveys, and qualitative interviews, we examined the impact of allowing patients to view their test results via patient portal in one large health system. Quantitative data were collected for new users and all users of the patient portal. Qualitative interviews occurred with patients who had received an HbA1c or abnormal Pap result. Survey participants were active patient portal users. Our main measures were patient portal usage, factors associated with viewing test results and utilizing care, and patient and provider experiences with patient portal and direct release. Usage data show 80% of all patient portal users viewed test results during the year. Of survey respondents, 82.7% noted test results to be a very useful feature and 70% agreed that patient portal has made their provider more accessible to them. Interviewed patients reported feeling they should have direct access to test results and identified the ability to monitor results over time and prepare prior to communicating with a provider as benefits. In interviews, both patients and physicians reported instances of test results leading to unnecessary patient anxiety. Both groups noted the benefits of results released with provider interpretation. Quantitative data showed patient utilization to increase with viewing test results online, but this effect is mitigated when results are manually released by physicians. Our findings demonstrate that patient portal access to test results was highly valued by patients and appeared to increase patient engagement. However, it may lead to patient anxiety and increase rates of patient visits. We discuss how such unintended consequences can be addressed and larger implications for meaningful use criteria.

Challenges and Solutions for Depression Prevention Research: Methodology for a Depression Prevention Trial for Older Adults with Knee Arthritis and Emotional Distress.

OBJECTIVE: To describe the methodology, challenges, and baseline characteristics of a prevention development trial entitled "Reducing Pain, Preventing Depression." METHODS: A sequential multiple assignment randomized trial (SMART) compared sequences of cognitive behavioral therapy (CBT) and physical therapy for knee pain and prevention of depression and anxiety. Participants were randomized to CBT, physical therapy, or enhanced usual care and followed for 12 months for new-episode depression or anxiety. Participants were age ≥ 60 with knee osteoarthritis and subsyndromal depression, defined as 9-item Patient Health Questionnaire (PHQ-9) score ≥1 (which included the endorsement of one of the cardinal symptoms of depression [low mood or anhedonia]) and no diagnosis of major depressive disorder per the Structured Clinical Interview for DSM-IV. Depression and anxiety severity and characterization of new episodes were assessed with the PHQ-9, Generalized Anxiety Disorder-7, and the PRIME-MD. Knee pain was characterized with the Western Ontario McMaster Arthritis Index. Response was defined as at least "Very Much Better" on a Patient Global Impression of Change. RESULTS: At baseline there were 99 patients with an average age of 71; 61.62% were women and 81.8% white. The average PHQ-9 was 5.6 and average Generalized Anxiety Disorder-7, was 3.2. Most were satisfied with the interventions and study procedures. The challenges and solutions described here will also be used in a confirmatory clinical trial of efficacy. CONCLUSION: A SMART design for depression and anxiety prevention, using both CBT and physical therapy, appears to be feasible and acceptable to participants. The methodologic innovations of this project may advance the field of late-life depression and anxiety prevention.

What can be learned from the types of community benefit programs that hospitals already have in place?

After implementation of the Patient Protection and Affordable Care Act (ACA) how will tax-exempt hospitals adjust their community benefit programs to maintain their non-profit status? This literature review categorized existing hospital-based community benefit programs by reviewing published articles that met the following inclusion criteria: affiliated or funded by a hospital; described the program design; focused on community benefit or outreach; evaluated program outcomes; located within the United States. Of 4,917 original citations, we reviewed 265 full-text articles. One hundred and six (106) programs met all inclusion criteria and were used to develop a hospital-based community benefit program taxonomy. Results indicate that programs to enhance patient care, clinic-based programs and programs with a community partner make up the majority of community benefit programs (25%, 28% and 31%, respectively). Few programs were rigorously evaluated or provide evidence of program impact. Hospitals should work with public health professionals to design, implement, and evaluate their community benefit programs.

Homophily and health behavior in social networks of older adults.

A common network phenomenon, homophily, involves developing relationships with others who are similar to you. The intent of this study was to determine if older adults' health behaviors were shared within social networks. We interviewed older adults from low-income senior housing (egos) on egocentric social network characteristics and key health behaviors for themselves and for named social ties (alters). Findings suggest strong effects for homophily, especially for those who smoked and were physically inactive. Public health interventions for older adults should consider the influence that social relationships have on personal health behaviors. Network-based interventions may be required.

Barriers to treatment and culturally endorsed coping strategies among depressed African-American older adults.

OBJECTIVE: Older adults are particularly vulnerable to the effects of depression, however, they are less likely to seek and engage in mental health treatment. African-American older adults are even less likely than their White counterparts to seek and engage in mental health treatment. This qualitative study examined the experience of being depressed among African-American elders and their perceptions of barriers confronted when contemplating seeking mental health services. In addition, we examined how coping strategies are utilized by African-American elders who choose not to seek professional mental health services. METHOD: A total of 37 interviews were conducted with African-American elders endorsing at least mild symptoms of depression. Interviews were audiotaped and subsequently transcribed. Content analysis was utilized to analyze the qualitative data. RESULTS: Thematic analysis of the interviews with African-American older adults is presented within three areas: (1) Beliefs about Depression Among Older African-Americans; (2) Barriers to Seeking Treatment for Older African-Americans; and (3) Cultural Coping Strategies for Depressed African-American Older Adults. CONCLUSION: Older African-Americans in this study identified a number of experiences living in the Black community that impacted their treatment seeking attitudes and behaviors, which led to identification and utilization of more culturally endorsed coping strategies to deal with their depression. Findings from this study provide a greater understanding of the stigma associated with having a mental illness and its influence on attitudes toward mental health services.

Attitudes and beliefs about mental health among African American older adults suffering from depression.

Depression among older adults is a major public health concern leading to increased disability and mortality. Less than 3% of older adults utilize professional mental health services for the treatment of depression, less than any other adult age group. And despite similar rates of depression, African Americans are significantly less likely to seek, engage and be retained in professional mental health services than their white counterparts. Cultural differences in the way depression symptoms are manifested, defined, interpreted and labeled may in part explain some of these racial differences in help-seeking behaviors. Focus group methodology was utilized to identify and explore attitudes and beliefs about depression and mental health treatment utilization among 42 older African Americans who had recently suffered a major depressive episode. Thematic analysis of identified six overarching themes: (a) perceptions of depression, (b) the African American experience, (c) seeking treatment as a last resort, (d) myths about treatment, (e) stigma associated with seeking treatment and (f) culturally appropriate coping strategies. We discuss implications for practice, education and research.

Daily temporal self-care responses to osteoarthritis symptoms by older African Americans and whites.

Osteoarthritis (OA) is the most prevalent form of arthritis and is among the most prevalent chronic conditions in the USA. Because there is no known cure for OA, treatment is directed towards the alleviation of pain, improving function, and limiting disability. The major burden of care falls on the individual, who tailors personal systems of care to alleviate troublesome symptoms. To date, little has been known about the temporal variations in self-care that older patients with OA develop, nor has it been known to what extent self-care patterns vary with ethnicity and disease severity. This patient-centered descriptive study was designed to demonstrate the self-care strategies used by older African Americans and whites to alleviate the symptoms of OA on a typical day and during specific segments of a typical day over the past 30 days. A sample of 551 older adults participated in in-depth interviews, and the authors clustered their responses into six categories. Findings showed that the frequency of particular behaviors varied by time of day, disease severity, and race. Overall, patterns of self-care behaviors were similar between African Americans and whites, but African Americans used them in different proportions than whites. This study contributes to our knowledge of the dynamic and changing nature of self-care actions even within a single day. By defining how self-care is used in one illness by two different ethnic groups, we may be able to design appropriate educational programs that are more culturally specific to better meet the needs of patients with OA.

Contributing factors and issues associated with rural ambulance crashes: literature review and annotated bibliography.

Ambulance crashes occur with greater frequency and severity than crashes involving vehicles of similar size and weight characteristics. Crashes in rural areas tend to be more severe in terms of injury or death to vehicle occupants. The purpose of this article was to examine the extant literature, as well as summarize and discuss the overlapping findings of that body of literature. A stepwise literature search was conducted using the following MeSH search terms ambulance; accident, traffic; emergency medical technician; occupational health; and rural in descending combination. MEDLINE was used as the primary database but was augmented by searches of Academic Search Premier, Comprehensive Index of Nursing, Allied Health Literature, and ProQuest Dissertation International. The search resulted in 32 article citations, and of these, 28 were included. An annotated bibliography is followed by a discussion and conclusion that identify opportunities for prevention activities in the areas of education, enforcement, and engineering.

Attenuated central nervous system infection in advanced HIV/AIDS with combination antiretroviral therapy.

BACKGROUND: Before the introduction of combination antiretroviral therapy (CART), neurological disease correlated with cerebrospinal fluid (CSF) levels of human immunodeficiency virus (HIV) RNA. OBJECTIVE: To investigate the relationships among HIV RNA levels, immune activation markers, and neurological status in patients receiving CART. DESIGN: Multicenter cohort study. SETTING: Academic neurology departments. PATIENTS: A total of 371 patients unselected for neurological complaints and with CD4 cell counts less than 200/microL or with cognitive symptoms and CD4 cell counts less than 300/microL were enrolled into the Northeastern AIDS Dementia cohort in 1998-2002. Diagnoses of HIV-associated dementia (HIV-D) and minor cognitive-motor disorder (MCMD) were obtained with a computerized algorithm. Plasma and CSF levels of HIV RNA, monocyte chemotactic protein 1, macrophage colony-stimulating factor, and tumor necrosis factor alpha were quantified. RESULTS: The mean +/- SD age was 41.5 +/- 7.2 years, and the mean +/- SD educational level was 12.3 +/- 2.2 years. Seventy percent of the cohort was black, and 30% were women. The mean +/- SD CD4 cell count was 136.8 +/- 87.9/microL, and CART was used in 71%. Twenty-nine percent of the patients were unimpaired (n = 106), 36% had MCMD (n = 133), and 35% had HIV-D (n = 128). Mean log(10) CSF HIV RNA copies per milliliter was 2.6 +/- 0.8, with no differences among the neurological groups, even after adjustments for baseline CD4 cell counts and antiretroviral therapy. Cerebrospinal fluid HIV RNA was undetectable in 47% of unimpaired, 46% of MCMD, and 43% of HIV-D patients (P = .91). Plasma levels of monocyte chemotactic protein type 1 and tumor necrosis factor alpha correlated weakly with HIV RNA levels but did not distinguish those with neurological deficits. CONCLUSIONS: In contrast to observations in individuals not treated with CART, we found no relationship between CSF markers and neurological status in this CART-using cohort with advanced HIV/AIDS. This was not explicable by demographic differences or plasma virological control. CART may substantially attenuate the degree of central nervous system HIV infection and immune activation, and in CART users, CSF HIV RNA and immune activation markers may fail to discriminate milder degrees of HIV-D and MCMD.

HIV-associated cognitive impairment before and after the advent of combination therapy.

The objective of this study was to describe the occurrence of HIV dementia and neuropsychological testing abnormalities in a new cohort of HIV-seropositive individuals at high risk for HIV dementia and to compare these results to a cohort before the advent of highly active antiretroviral therapy (HAART). HAART has been associated with improvements in cognitive performance in some HIV-infected patients. However, it is uncertain whether HAART has changed the frequency of specific neurocognitive abnormalities. Baseline data from 272 HIV-seropositive subjects in the Dana cohort recruited from January, 1994, to December, 1995, and 251 HIV-seropositive subjects in the Northeastern AIDS Dementia Consortium (NEAD) cohort recruited from April, 1998, to August, 1999, were compared. Participants in both cohorts received nearly identical assessments. After adjusting for differences in age, education, gender, race, and CD4 count between the two cohorts, there were no differences in the occurrence of HIV dementia or abnormalities either 1 SD or 2 SDs below established norms for any of the neuropsychological tests. Even though HAART has reduced the incidence of HIV dementia, HIV-associated cognitive impairment continues to be a major clinical problem among individuals with advanced infection.
