Jejunal Diverticulitis: A Rare Diverticular Disease of the Bowel.

Diverticulosis is an out-pocketing of the bowel wall that can affect the small bowel through the large bowel. Small bowel diverticulosis is rare and not as common as colonic diverticulosis, which is an important diagnosis for hospitalizations. Moreover, jejunal diverticulosis is rare among cases of small bowel diverticulosis. Jejunal diverticulitis is one of the complications of jejunal diverticulosis that can be conservatively managed with antibiotics instead of surgery. We report a case of a 41-year-old African American man who presented with vague epigastric pain and was diagnosed with adhesive jejunal diverticulitis upon contrast-enhanced computed tomography of the abdomen. The patient did not develop any life-threatening complications such as perforation or peritonitis, and recovered after conservative management with antibiotics. Adhesive jejunal diverticulitis with fat stranding was the distinctive finding in our patient, as he might have had multiple asymptomatic episodes. Initial diagnostic modalities include radiography and contrast-enhanced computed tomography. Enteroclysis is the most reliable and accurate diagnostic modality, but is not available in all urgent settings. Recently, endoscopy has replaced radiological studies. Conservative management is adequate for uncomplicated cases of jejunal diverticulitis. However, surgical intervention is required in most cases of complicated jejunal diverticulosis, or mortality rates will be high.

Use of an online personal health record's Track Health function to promote positive lifestyle behaviors in Veterans with prediabetes.

This pilot 3-month clinical trial investigated the feasibility, effectiveness, and acceptability of using the Track Health function of the Veterans Health Administration's personal health record for eliciting a more positive physical activity and dietary intake lifestyle in a sample of 38 overweight and obese Veterans with prediabetes. Comparisons between baseline and 3 months post-intervention indicated significant improvements in weight, physical activity, abdominal circumference, and blood pressure. Use of a personal health record that users can identify with and find usable and useful coupled with instruction targeting critical functionalities could potentially promote healthy behavioral lifestyle changes.

Dramatic Reduction in 30-Day Readmissions Through High-Risk Screening and Two-Phase Interdisciplinary Care.

OBJECTIVES: Thirty-day readmissions are common, serious, and costly. Most important, often they are preventable. The purpose of this quality improvement study was to evaluate an interdisciplinary, two-phase intervention to reduce 30-day readmissions among high-risk medical patients. One or two high-risk patients were selected each weekday by a hospitalist using literature-based, locally tested criteria that included common medical illnesses, active psychiatric illness, and recent or recurrent hospital admissions. METHODS: Patients admitted to 1 of 5 medical hospitalist teams were selected to receive the intervention; patients admitted to the 4 remaining teams were used for comparison. The two-phase care coordination intervention consisted of a daily interdisciplinary team meeting for the selected high-risk patients and postdischarge interventions that included outpatient care coordination until the patients' first follow-up appointment. The care plan addressed medical/geriatric assessment, social stability, medication reconciliation, nutritional needs, care coordination including future appointments/testing, and community services. Eighty-five patients in the intervention group were compared with 84 patients from the comparison group using propensity score matching. Patient characteristics were similar at baseline. RESULTS: The intervention group demonstrated a reduction in 30-day readmissions by 52% (11 vs 23, P = 0.019). Length of stay was reduced: 5.5 days compared with 7.2 days (P = 0.258). CONCLUSIONS: This intervention produced a significant reduction in 30-day readmissions for high-risk patients and a trend for shorter lengths of stay compared with similarly matched patients. Future research trials are needed to verify these results.

Healthcare Utilization by Frail, Community-Dwelling Older Veterans: A 1-Year Follow-up Study.

OBJECTIVES: Frailty is a prevalent clinical syndrome associated with a high risk of adverse health outcomes, including disability, morbidity, and mortality, that has become a major challenge for the healthcare system. The aim of this prospective study was to determine the level of healthcare utilization in prefrail and frail community-dwelling older military veterans. METHODS: We studied a cohort of community-dwelling older veterans aged 65 years and older 1 year at the Miami Veterans Affairs Medical Center to determine their levels of healthcare utilization. We administered the 5-item FRAIL (Fatigue, Resistance, Ambulation, Illnesses, & Loss of Weight) scale, from which patients were categorized into three groups: robust, prefrail, and frail. Chart reviews were conducted to confirm weight loss and number of illnesses. One year later, information regarding hospital admissions, emergency department (ED) visits, and primary care visits was obtained. RESULTS: We evaluated 291 participants, mean age 74 ± 8 years, 112 (38.5%) of whom were African American, 179 (61.5%) were white, and 40 (13.7%) were Hispanic. Overall, 49 (16.8%) participants were frail, and 161 (55.4%) prefrail. After adjusting for age and Charlson Comorbidity Index, frail status was associated with ED admission (odds ratio [OR] 2.7, 95% confidence interval [CI] 1.2-6.1) and primary care visits (OR 3.4, 95% CI 1.5-7.3); however, it was not significantly associated with hospital admission (OR 2.2, 95% CI 0.9-5.2). CONCLUSIONS: In a sample of community-dwelling older veterans, frailty was found to be significantly associated with an increased frequency of ED visits and primary care visits, but not with hospital admissions. Identifying patients with frailty may allow for targeted interventions that improve healthcare outcomes and may reduce healthcare utilization.

Outcomes of a Mobile Phone Intervention for Heart Failure in a Minority County Hospital Population.

BACKGROUND: Chronic heart failure (HF) causes significant morbidity, mortality, and cost. Managing HF requires considerable self-management skills and self-efficacy. Little information exists about feasibility and potential impact of a mobile monitoring intervention to improve self-efficacy and quality of life (QoL) among minority patients with HF. MATERIALS AND METHODS: We developed a mobile phone-assisted case management program and tested its impact on outcomes in minority patients with HF in a 2:1 randomized controlled trial. We evaluated self-care efficacy, knowledge, behavior, and QoL at baseline and 3 months. RESULTS: We enrolled 61 participants: intervention 42, usual care 19; mean age ± SD: 55 ± 10 years; 64% male; 75% white Hispanic, 25% African American; and 56% high school education or less. Comparison of the two groups with respect to changes from baseline to 3 months showed significant differences for Self-Efficacy for Managing Chronic Disease (2.09 ± 2.32, p-value = 0.005); health distress scale (-1.1 ± 1.5, p-value = 0.017); and QoL (Role Physical, 23.6 ± 44.5, p-value = 0.042, and General Health, 11.1 ± 14.2, p-value = 0.012). CONCLUSIONS: A mobile phone-based disease management program may help improve self-care efficacy and QoL in a minority population and offers a modality to help reduce ethnic disparity.

Mobile Phone Intervention for Heart Failure in a Minority Urban County Hospital Population: Usability and Patient Perspectives.

BACKGROUND: Chronic heart failure (HF) is a complex and costly disease. Daily weight and symptom monitoring is the cornerstone of HF management. Little information exists about feasibility of a mobile monitoring intervention among minority patients with HF. METHODS: We developed and tested usability of a mobile-monitoring system in minority patients with HF in a 2:1 randomized controlled trial. We tracked usage and obtained feedback on usability and the system overall at 1, 2, and 3 months. RESULTS: Forty-two participants aged 53.0 ± 9.4 years (mean ± standard deviation) were randomized to the mobile-monitoring intervention group. They included the following: 67% males, 76% White Hispanics, 21% African Americans, and 52% with high school education or less. Over the 3-month intervention period, 26 (62%) participants used the system over 50% of the time. Overall, on a 1.0-7.0 scale for both, program satisfaction scores were excellent (mean 6.84 ± 0.46), and the usability ratings were all above 6.0. Comparing 1- to 3-month responses, there was a substantial increase in the percentage of participants who felt the system was easy to use after they had gotten used to it (84% vs. 94%) and that navigating the system was not complicated (78% vs. 84%). Almost all participants said that the program made them feel more secure about their health and that they would stay enrolled in a program like this. None of them had used a similar system before. CONCLUSIONS: A mobile phone-based disease management program is feasible in a minority county hospital population and offers a modality to help reduce ethnic disparity.

The Association of Graph Literacy With Use of and Skills Using an Online Personal Health Record in Outpatient Veterans.

Personal health records (PHRs) are intended to increase patients' access to and ownership over their health care information for self-management purposes. The purpose of this study was to determine the association of graph literacy with adoption of an online PHR and, among adopters with self-reported skills, the frequency of use and intent to return to use the PHR . We conducted a cross-sectional survey of veterans receiving outpatient care. We measured health literacy, numeracy, graph literacy, and Internet and PHR adoption and use. We compared subgroups of veterans using analyses of covariance. We used hierarchical logistic regression models to estimate the effects of the literacy variables on PHR use. A total of 600 veterans (age = 22-94) participated in the survey. After we adjusted for known covariates, we found that adopters of a PHR were more likely to demonstrate higher health and graph literacy than nonadopters. Among PHR adopters, self-reported frequent and skillful users were more likely to have higher graph literacy than lower frequency and less skillful users. Adopters with higher intentions to return to use the PHR were more likely to show lower graph literacy than those less likely to return to use the PHR. Inadequate graph literacy was associated with lower adoption of a PHR and, among users, with lower self-reported frequent use and skills . As PHR use becomes more widespread, stakeholders will need to consider patients' levels of graph literacy when implementing PHRs.

Effects of an Avatar-Based Anti-Smoking Game on Smoking Cessation Intent.

The purpose of this study was to compare the effects of a computer-based anti-smoking game on the intent and motivation to quit tobacco. Smokers with nicotine dependence were briefly exposed to an anti-smoking game with or without an avatar resembling the smoker's self. The computer-based anti-smoking game improved participants' immediate intent and motivation to quit smoking. Embedding an avatar resembling self into the game did not result in added benefits.

The Communication of Global Cardiovascular Risk by Avatars.

Communicating numerical estimates of cardiovascular risk (CVR) to patients encourage risk reduction actions. Avatars may enhance the risk messages ability to improve persuasion to adhere to healthy behaviors. We compared the efficacy of a computer-based aid communicating CVR with and without animated avatars for improving intention to adhere to lifestyle changes. Males with intermediate to high CVR received their risk message in 2 versions: an avatar using voice; voice only. Forty-one participants completed the study. Intent to change lifestyle showed a significant effect favoring the avatar (moderate effect size). Intent to follow medical treatments also showed a significant effect favoring the avatar (moderate effect size). An avatar-based computer aid significantly increased participants' intention to adhere to positive behavioral changes.

An overactive bladder online self-management program with embedded avatars: a randomized controlled trial of efficacy.

OBJECTIVE: To determine whether an avatar-based, online, self-management program is an effective therapeutic approach for women with overactive bladder (OAB). OAB is a highly prevalent symptom complex that significantly impacts health-related quality of life (HRQOL). Behavioral interventions can produce substantial improvement in symptoms and HRQOL. Online education programs offer patients with OAB an alternative to face-to-face self-management instruction. Evidence suggests that avatars (digital humans) embedded into online programs may help persuade and motivate patients to adopt healthy behaviors. METHODS: In a 12-week, randomized, controlled trial, women (aged >55 years) with symptoms of OAB for at least 3 months were randomized to 2 versions of a 3-part, online, self-management program. After collecting the baseline metrics, the intervention group viewed a generic avatar coach with a self-avatar peer mentor designed to resemble the participant, and the control group viewed the identical online program with voice only. Participants viewed part 1 at week 1 and parts 2 and 3 at week 6. Participants completed daily bladder diaries throughout the 12-week period and OAB-related outcome measures at weeks 1, 6, and 12. RESULTS: Forty-one women completed the study (mean age = 61 years, standard deviation = 6). The analysis of covariance of week-12 outcome measures with the baseline as covariates demonstrated significant improvements in the intervention group in OAB questionnaire HRQOL (P = .02; large effect), 24-hour frequency (P <.001; large effect), night-time urination (P <.001; large effect), urgency (P <.001; large effect), and urge incontinence (P <.001; large effect). CONCLUSION: An avatar-based intervention embedded into an online self-management program improved OAB HRQOL and symptoms in women.

Group-based differences in anti-aging bias among medical students.

Medical students (MS) may develop ageist attitudes early in their training that may predict their future avoidance of caring for the elderly. This study sought to determine MS' patterns of explicit and implicit anti-aging bias, intent to practice with older people and using the quad model, the role of gender, race, and motivation-based differences. One hundred and three MS completed an online survey that included explicit and implicit measures. Explicit measures revealed a moderately positive perception of older people. Female medical students and those high in internal motivation showed lower anti-aging bias, and both were more likely to intend to practice with older people. Although the implicit measure revealed more negativity toward the elderly than the explicit measures, there were no group differences. However, using the quad model the authors identified gender, race, and motivation-based differences in controlled and automatic processes involved in anti-aging bias.

Computer-based programmed instruction did not improve the knowledge retention of medication instructions of individuals with type 2 diabetes mellitus.

PURPOSE: The purpose of this study was to investigate whether computer-based programmed instruction (CPI) with a dynamic avatar (DA) improves retention of medication information better than text (controls) or better than CPI with text (T-CPI), CPI with voice (V-CPI), or CPI with static avatar with text (SA-CPI). METHODS: Participants with type 2 diabetes mellitus were enrolled in a randomized controlled trial comparing TDS with CPI in 4 conditions (T-CPI, V-CPI, SA-CPI, and DA-CPI). CPI sequentially delivers segmented information in text or voice followed by a multiple-choice question. Immediately after the user selects an option, CPI delivers elaborated feedback. Satisfaction was measured immediately after the interventions, and medication knowledge was measured at 2 weeks. RESULTS: One-hundred fifty individuals (30 per group) with a mean age 62 years (standard deviation [SD] 7.99 years) participated. There were no baseline differences in race, body mass index, education, and health literacy. Medication knowledge retention at 2 weeks was not significantly different between the groups, df(4), F = 0.17, P = .95 (TDS, mean = 25.43, SD = 5.11; T-CPI, mean = 25.07, SD = 4.98; V-CPI, mean = 25.77, SD = 4.89; SA-CPI, mean = 25.83, SD = 5.31; and DA-CPI, mean = 24.93, SD = 6.25). Satisfaction scores were significantly lower for TDS, df(4), F = 3.11, P = .01. CONCLUSIONS: CPI did not improve medication knowledge retention at 2 weeks. CPI led to higher patient satisfaction compared with controls.
