Volunteer-Based Social Support Structures and Program Exposure Outcomes in an Adolescent Young Adult Palliative Care Peer Support Program.

Objective: To conduct a social network analysis (SNA) of patient-volunteer networks and assess the impact of patient characteristics on network measures. Background: Volunteers play a critical role in providing peer support to adolescent and young adult (AYA) palliative care patients. Streetlight at UF Health is a peer support palliative care program for hospitalized AYAs that aims at forming positive peer relationships through volunteer visits, events, and a virtual online health community. Methods: Data were collected on patient characteristics, hospitalizations, average length of stays (LOS), and volunteer visitation records. Egocentric SNAs were conducted on each patient to calculate network outcomes. Study participants were AYA patients (N = 69), enrolled in the US-based Streetlight program at UF Health Shands Hospital. Results: The LOS was significantly associated with network size (B = 0.583; 95% confidence interval; CI [0.463 to 0.702]). Autoimmune patients had smaller network sizes when controlling for LOS. Total hospital admissions predicted - 0.172 ([- 0.263 to - 0.080]) lower average repeat visits. Higher average repeat visits were predicted for patients who had cancer (B = 0.246 [0.046 to 0.447]) and awaiting organ transplantation (B = 0.370 [0.082 to 0.658]). Although cystic fibrosis patients received more visits (B = 0.364 [0.003 to 0.724]) compared with other illness populations, the network density was lower (B = - 0.580 [1.01 to - 0.155]). Cancer patients had networks with a higher diversity in volunteer repeat visits (B = 0.714 [0.312 to 0.920]). Conclusions: Significant relationships between patient characteristics and network outcomes highlight the differences in social support service delivery among diverse populations. These analyses can be utilized in practice to guide program delivery for high-need patients.

Evaluating True Barriers to Dental Care for Patients with Periodontal Disease.

BACKGROUND: The cost of care is often reported as a primary reason why patients fail to seek dental treatment; however, this may not the only component. AIMS/OBJECTIVES: To examine an underserved population's perspective on the importance of dental care and barriers they face to seek treatment. The effectiveness of compliance incentives, such as gift cards, was also examined. METHODS: We conducted a survey study to gain insight of an underserved population's perspective of barriers to care and correlated the reported barriers with the true reasons of missed appointments in our study cohort. Appointment compliance was also examined before and after implementation of gift card incentives, appoitment reminder letters and additional staff. RESULTS: Most patients felt dental care was important/very important to them. However, no correlations were found between survey responses and true reasons for missing appointments. Eighty-seven percent of patients report having some form of financial difficulty and compliance statistically improved after implementation of financial compensation in this population (69% completed appointments before gift card implementation versus 75% after gift card implementation, p=0.01), but not after the implementation of additional appointment reminders and contact staff. DISCUSSION: Although the majority of patients reported dental care was important to them, there was an average of 31% missed appointments for patients who completed the survey and no correlations were found between the information patients reported and true reasons for non-compliance. Interestingly, even though care was free of charge, most patients reported to be in some form of financial difficulty and compliance was slightly improved through the implementation of financial compensation. Other potential barriers that need to be further examined include economic barriers, transportation, insurance utilization, and patient anxiety towards dental care. CONCLUSION: A survey is a resource to identify reasons why patients abstain from seeking care but may be not the best one as reasons reported do not correlate with true reasons of appointment failure. Financial compensation was shown to improve compliance with appointments. Further information gathering is necessary to gain insight into true barriers to dental care within an underserved population.

Oral cancer knowledge and screening behavior among smokers and non-smokers in rural communities.

BACKGROUND: Research suggests having an oral and pharyngeal cancer (OPC) examination for early diagnosis can increase survival rate. However, the OPC screening rate is low in certain populations. To improve OPC screening rate, this study identified factors that are associated with having an OPC examination. METHODS: Participants with landlines and aged 25 years and older were recruited from six northern Florida counties. Bivariate and logistic regressions were used to predict the outcome of whether the participants had ever had an OPC examination as well as whether participants had ever heard of an OPC examination. RESULTS: Of 2260 participants with a mean age of 55.9 ± 15.0 years, the majority of participants never smoked (53.4%), self-identified as Whites (70.6%), and had some college or 2-year degree education (30.3%). Smokers were significantly less likely to have ever heard of an OPC examination than those who never smoked. Significant interaction between smoking status and race, and smoking status and social support interaction were found. Whites who never smoked were more likely to have had an OPC examination than non-Whites who never smoked. Former and current smokers with greater social support were more likely to have had an OPC examination than those with lower social support. CONCLUSION: The findings from this study inform the need to enhance the awareness of having an OPC examination among smokers and to reduce barriers for racial minority populations to receive an OPC examination. Future research is warranted to develop interventions to target certain populations to improve the rate of OPC examination.

Determinants of dentists' readiness to assess HPV risk and recommend immunization: A transtheoretical model of change-based cross-sectional study of Ontario dentists.

OBJECTIVES: To evaluate dentists' readiness to assess the history of human papilloma virus (HPV) infections and recommend immunization among their patients. MATERIALS AND METHODS: A link to a self-administered questionnaire was emailed to Ontario dentists. Dentists' readiness and its determinants were assessed based on Transtheoretical Model's 'stages' and 'processes' of change, respectively. Based on their current practices, dentists were either assigned to 'pre-action' or 'action+' stages. RESULTS: Of the 9,975 dentists contacted, 932 completed the survey; 51.9% participants were in action stage to assess the history of HPV infections and 20.5% to recommend immunization. Internationally-trained and those whose office's physical layout was not a concern to discuss patients' sexual history were more likely to assess the history. Dentists with higher knowledge about HPV vaccines, not concerned about the HPV vaccine safety, comfortable discussing sex-related topics with patients, or willing to exceed their scope of practice were more ready to recommend HPV immunization to their patients. CONCLUSION: Improving Ontario dentists' knowledge and communication skills and changing their self-perceived role regarding HPV infections and vaccination can increase their capacity to minimize the burden of HPV infections.

Dentists' Capacity to Mitigate the Burden of Oral Cancers in Ontario, Canada.

BACKGROUND: In Canada, although the incidence of smoking-related oral cavity cancers has decreased, oropharyngeal cancers associated with human papilloma virus (HPV) are on the rise. During their routine interactions with patients, dentists have the opportunity to intervene. This study was conducted to assess dentists' capacity to prevent and detect oral cancers and to identify the barriers and facilitators that affect this capacity. METHODS: A 25-item, self-administered questionnaire was emailed to Ontario dentists through their regulatory body. It aimed to assess their perceptions about various aspects of oral cancer prevention and detection, including their knowledge, attitudes and practices. A binary logistic regression model was constructed for each modifiable risk factor (smoking, alcohol use, HPV) to identify the predictors of dentists' readiness to discuss with patients the connection between risk factors and oral cancers. RESULTS: Of the 9975 dentists contacted, 932 completed the survey. Most respondents (92.4%) believed that they are adequately trained to recognize the early signs and symptoms of oral cancer. However, only 35.4% of respondents said that they are adequately trained to obtain biopsy samples from suspected lesions. In addition, only a small proportion (< 40%) of the dentists believed that they are adequately trained to address relevant risk factors. Compared with dentists who said that they are adequately trained and currently assess a given risk factor, the odds of discussing the risk factor were consistently and significantly lower among those who said that they are inadequately trained (OR: smoking 0.11, alcohol 0.52, HPV 0.36) and among those who do not currently assess that risk factor (OR: smoking 0.12, alcohol 0.22, HPV 0.23). CONCLUSIONS: This study suggests that the capacity of Ontario dentists to detect and prevent oral cancers is limited by lack of training in using oral cancer screening tools and addressing risk factors. To mitigate this barrier, dentists' capacity could be enhanced by improving their training in detecting oral cancers and their readiness to assess and address the risk factors.

Classification Tree Analysis of Factors Associated with Oral Cancer Exam.

Objective: In this study, we performed a classification tree analysis (CTA) to identify population subgroups that are less likely to have an oral cancer examination (OCE). Methods: We conducted telephone surveys (N = 2401) of adults residing in north Florida to collect data on OCE status and potential OCE predictors including demographics, medical and dental experience, and psychosocial factors. The CTA algorithm exhaustive chi-square automatic interaction detector (E- CHAID) was employed to determine the relationships between OCE status and the predictors. Results: The overall OCE rate was 46.8% in our sample. Participants' rating of the dentist was the first level splitting variable, leading to 15 unique participant subgroups: (1) high dentist rating (N = 1269) led to 5 splits and 11 subgroups; (2) low dentist rating (N = 308) led to zero splits; and (3) no regular dentist (N = 824) led to 2 splits and 3 subgroups. Conclusions: The CTA has identified unique population subgroups that could be targeted in future tailored public health interventions. Among underserved populations, it is important to develop and implement community-based interventions that encourage regular dental visits and provide oral cancer self- examination education..

Impact of the promotora model on the improvement of oral health knowledge of caregivers / Impacto del modelo promotora en el mejoramiento del conocimiento sobre salud oral de los cuidadores

ABSTRACT Objective The objective of this quasi-experimental study was to determine the impact of the Promotora Model (PM) as an educational strategy to increase oral health knowledge in parents/caregivers of children aged 2-5 years at high risk for dental caries. Materials and Methods Sixty-three caregivers who provided informed consent were included in the study. A structured 37-item survey was administered prior to conducting the Promotora educational intervention (PEI) that covered oral health topics and behaviors. Three (3) months after the PEI session, during their child's next dental visit, the same instrument was administered to 46 of the parents/caregivers that had completed the first instrument. Results Most caregivers were Hispanic (73.9%) and 50% reported completing high school. Before PEI, 56.5% of participants scored as having "good" general knowledge. Three months after PEI, 82.6% achieved that score (paired sample T-test, p< 0.00001). Conclusion Based on the results, it was concluded that the PM significantly increased caregivers' oral health knowledge.(AU)

Dental Visits Mediate the Impact of Smoking on Oral Health.

OBJECTIVES: We explored the mediational relationships among smoking, dental visits, and oral health in a longitudinal study. METHODS: We selected a sample of adult residents of rural communities of North Central Florida and followed them for 3 years (final N = 1170). We examined the impact of smoking on oral health across time and conducted mediation analysis to quantify the effect of dental visits on the relationship between smoking and poor oral health. RESULTS: Our results showed that oral health declined across time for smokers but not for nonsmokers. The mediation analysis found that 18.3% of the difference in followup oral health between smokers and non-smokers was explained by smokers not having any dental visits in the last year. CONCLUSIONS: Our findings suggest that, given the low success rate of quitting smoking, promoting dental visits can help limit the negative effects of smoking on oral health. Future community prevention studies could encourage dental visits among smokers and provide educational materials that aim to increase knowledge of oral self-care.

Addressing Oral Health Disparities Via Educational Foci on Cultural Competence.

An ever-present challenge for the oral health profession is to reduce the extent of oral disease among racial and ethnic minority populations. Adding to this complex dilemma is the linkage between oral health and systemic health. We describe enhanced cultural competency, in the context of individual cultural beliefs, values, language, practice, and health behaviors, among dental professionals, as one approach to meeting the dental care needs of the underserved. An overview and examples of teaching methods used by University of Florida dental educators to enhance student cultural competency is provided. Evidence-based evaluation results provide evidence of methodology efficacy. We conclude by describing actions that can be implemented by academic dental institutions to facilitate development of culturally competent practitioners.

Types and Factors Associated With Online Health Information Seeking Among College Men in Latino Fraternities: A Qualitative Study.

Despite the fact that a large percentage of Americans go online to seek health information, literature pertaining to online health information (OHI) seeking among college men in Latino fraternities (CMLF) has been nonexistent. Thus, the purpose of this study was to (a) identify the types of OHI that CMLF seek and (b) to determine the factors motivating OHI seeking among CMLF. Four 1- to 1.5-hour focus groups were conducted in two public universities in Florida with 41 college-aged Latino males in an established Latino fraternity. E-mails were used to recruit fraternity members. Qualitative analysis of the focus group transcripts identified that CMLF search for a variety of OHI types including searches on symptoms, diagnoses, weight loss, and treatments for conditions or diseases among other types of OHI. Factors motivating OHI seeking included informational needs of others and concerns for others, worries due to lack of health insurance, preoccupations with health condition, concerns over physical appearance, and clarification through social media. CMLF may be elicited to serve as information conduits to increase access to health information on chronic diseases for older non-English-speaking Latino adults. Lack of health insurance along with other factors in this segment of the population have led to self-diagnosis and self-treatment of illness. Thus, empirical research and health promotion on the potential risks due to self-diagnosing and self-treatment of illness is warranted among CMLF.

The reliability of psychological instruments in community samples: A cautionary note.

Although researchers norm and validate measures of psychological constructs largely on educated samples, they often use these instruments more broadly, assuming generalizability. We examined whether the assumption of generalizability is warranted. We administered three commonly used psychological measures-the Behavioral Activation/Behavioral Inhibition Scale, the Regulatory Focus Questionnaire, and the Need for Cognition Scale-to a community sample (N = 332) with limited education. For the three instruments, five of seven scales/subscales had unsatisfactory reliabilities. Internal consistency was lowest among participants with less education. The results suggest that instruments normed on educated samples may not generalize to uneducated samples.

Trends in dental-related use of hospital emergency departments in Florida.

OBJECTIVES: The inability to access regular dental care may lead to care seeking at hospital emergency departments (EDs). However, EDs generally are not equipped or staffed to provide definitive dental services. This study examined trends and patterns of hospital ED use for dental-related reasons in Florida, a large, diverse state with serious barriers to accessing dental care. METHODS: Data for this study were drawn from ambulatory ED discharge records compiled by Florida's Agency for Health Care Administration for 2005-2014. Visits for dental-related reasons in Florida were defined by the patient's reported reason for seeking care or the ED physician's primary diagnosis using ICD-9-CM codes. We calculated frequencies, age-specific and age-adjusted rates per 100,000 population, and secular trends in dental-related ED visits and their associated charges. RESULTS: The number of dental-related visits to Florida EDs increased each year, from 104,642 in 2005 to 163,900 in 2014; the age-adjusted rate increased by 43.6 percent. Total charges for dental-related ED visits in Florida increased more than threefold during this time period, from $47.7 million in 2005 to $193.4 million in 2014 (adjusted for inflation). The primary payers for dental-related ED visits in 2014 were Medicaid (38 percent), self-pay (38 percent), commercial insurance (11 percent), Medicare (8 percent), and other (5 percent). CONCLUSIONS: Dental-related visits to hospital EDs in Florida have increased substantially during the past decade, as have their associated charges. Most patients did not receive definitive oral health care in EDs, and this trend represents an increasingly inefficient use of health care system resources.

Assessing Oral Cancer Awareness Among Rural Latino Migrant Workers.

Latino migrant farm workers suffer significant health disparities, including poor oral health. The purpose of this research was to assess Latino migrant farm workers' OC awareness, including knowledge and care-seeking behaviors. A 42-item survey was developed. Trained, bilingual researchers verbally administered the survey to migrant farm workers in Hillsborough County, Florida. Frequencies and descriptive statistics were generated to report baseline data. The sample consisted of 53.7 % female respondents. The mean age for males and females respectively was 38.7 and 39.2. Most respondents had attended grade school; 6.7 % never attended school. Perceptions of cancer susceptibility were present; knowledge of OC risk factors, signs and symptoms was low. Participants were unlikely to seek preventive care. The results contribute to the limited studies regarding Latino migrant farm workers and oral cancer risk factor awareness and knowledge. Findings highlight factors influencing motivation and care-seeking behaviors, as well as provide guidance for development of educational materials.

Older Adults' Use of Online and Offline Sources of Health Information and Constructs of Reliance and Self-Efficacy for Medical Decision Making.

We know little about older adults' use of online and offline health information sources for medical decision making despite increasing numbers of older adults who report using the Internet for health information to aid in patient-provider communication and medical decision making. Therefore we investigated older adult users and nonusers of online and offline sources of health information and factors related to medical decision making. Survey research was conducted using random digit dialing of Florida residents' landline telephones. The Decision Self-Efficacy Scale and the Reliance Scale were used to measure relationships between users and nonusers of online health information. Study respondents were 225 older adults (age range = 50-92 years, M = 68.9, SD = 10.4), which included users (n = 105) and nonusers (n = 119) of online health information. Users and nonusers differed in frequency and types of health sources sought. Users of online health information preferred a self-reliant approach and nonusers of online health information preferred a physician-reliant approach to involvement in medical decisions on the Reliance Scale. This study found significant differences between older adult users and nonusers of online and offline sources of health information and examined factors related to online health information engagement for medical decision making.

Determinants of First-Time Cancer Examinations in a Rural Community: A Mechanism for Behavior Change.

OBJECTIVES: After conducting a media campaign focusing on the importance of oral and pharyngeal cancer (OPC) examinations, we assessed mechanisms of behavior change among individuals receiving an OPC examination for the first time. METHODS: We used data from 2 waves of telephone surveys of individuals residing in 36 rural census tracts in northern Florida (n = 806). The second survey occurred after our media intervention. We developed media messages and modes of message delivery with community members via focus groups and intercept interviews. We performed a mediation analysis to examine behavior change mechanisms. RESULTS: Greater exposure to media messages corresponded with heightened concern about OPC. Heightened concern, in turn, predicted receipt of a first-time OPC examination, but only among men. CONCLUSIONS: We extended earlier studies by measuring an outcome behavior (receipt of an OPC examination) and demonstrating that the putative mechanism of action (concern about the disease) explained the link between a media intervention and engaging in the target behavior. Improving the quality of media campaigns by engaging community stakeholders in selecting messages and delivery methods is an effective strategy in building public health interventions aimed at changing behaviors.

eHealth literacy and Web 2.0 health information seeking behaviors among baby boomers and older adults.

BACKGROUND: Baby boomers and older adults, a subset of the population at high risk for chronic disease, social isolation, and poor health outcomes, are increasingly utilizing the Internet and social media (Web 2.0) to locate and evaluate health information. However, among these older populations, little is known about what factors influence their eHealth literacy and use of Web 2.0 for health information. OBJECTIVE: The intent of the study was to explore the extent to which sociodemographic, social determinants, and electronic device use influences eHealth literacy and use of Web 2.0 for health information among baby boomers and older adults. METHODS: A random sample of baby boomers and older adults (n=283, mean 67.46 years, SD 9.98) participated in a cross-sectional, telephone survey that included the eHealth literacy scale (eHEALS) and items from the Health Information National Trends Survey (HINTS) assessing electronic device use and use of Web 2.0 for health information. An independent samples t test compared eHealth literacy among users and non-users of Web 2.0 for health information. Multiple linear and logistic regression analyses were conducted to determine associations between sociodemographic, social determinants, and electronic device use on self-reported eHealth literacy and use of Web 2.0 for seeking and sharing health information. RESULTS: Almost 90% of older Web 2.0 users (90/101, 89.1%) reported using popular Web 2.0 websites, such as Facebook and Twitter, to find and share health information. Respondents reporting use of Web 2.0 reported greater eHealth literacy (mean 30.38, SD 5.45, n=101) than those who did not use Web 2.0 (mean 28.31, SD 5.79, n=182), t217.60=-2.98, P=.003. Younger age (b=-0.10), more education (b=0.48), and use of more electronic devices (b=1.26) were significantly associated with greater eHealth literacy (R(2) =.17, R(2)adj =.14, F9,229=5.277, P<.001). Women were nearly three times more likely than men to use Web 2.0 for health information (OR 2.63, Wald= 8.09, df=1, P=.004). Finally, more education predicted greater use of Web 2.0 for health information, with college graduates (OR 2.57, Wald= 3.86, df =1, P=.049) and post graduates (OR 7.105, Wald= 4.278, df=1, P=.04) nearly 2 to 7 times more likely than non-high school graduates to use Web 2.0 for health information. CONCLUSIONS: Being younger and possessing more education was associated with greater eHealth literacy among baby boomers and older adults. Females and those highly educated, particularly at the post graduate level, reported greater use of Web 2.0 for health information. More in-depth surveys and interviews among more diverse groups of baby boomers and older adult populations will likely yield a better understanding regarding how current Web-based health information seeking and sharing behaviors influence health-related decision making.

Assessing Specific Sexual Behavior: Instrument Development and Validation Techniques.

Through the use of multi-modal methods, the purpose of this study was to develop and assess measurement properties of an instrument evaluating specific sexual behaviors of college students and the role alcohol intoxication plays in one's intention to participate in these behaviors. A modified version of N. Krause's instrument development process was applied to create a behavior-specific instrument assessing oral, vaginal, and anal sex behaviors. The process included a review by expert scholars in relevant fields, cognitive interviews with the target population using screen-capture program Camtasia, piloting to assess measurement scales, and a formal investigation. The applied instrument development process employed screen capture software and web-based surveying in a cost-effective format suitable for mixed-method measurement development. The development and application of the instrument provides a clearer understanding of the relationship between alcohol use and sexual activity and aids in the development of effective public health interventions and policies.

The digital health divide: evaluating online health information access and use among older adults.

OBJECTIVE: Innovations in health information technology (HIT) provide opportunities to reduce health care spending, improve quality of care, and improve health outcomes for older adults. However, concerns relating to older adults' limited access and use of HIT, including use of the Internet for health information, fuel the digital health divide debate. This study evaluated the potential digital health divide in relation to characteristic and belief differences between older adult users and nonusers of online health information sources. METHODS: A cross-sectional survey design was conducted using a random sample of older adults. A total of 225 older adults (age range = 50-92 years, M = 68.9 years, SD = 10.4) participated in the study. RESULTS: Seventy-six percent of all respondents had Internet access. Users and nonusers of online health information differed significantly on age (M = 66.29 vs. M = 71.13), education, and previous experience with the health care system. Users and nonusers of online health information also differed significantly on Internet and technology access, however, a large percentage of nonusers had Internet access (56.3%), desktop computers (55.9%), and laptop computers or netbooks (43.2%). Users of online health information had higher mean scores on the Computer Self-Efficacy Measure than nonusers, t(159) = -7.29, p < .0001. CONCLUSION: This study found significant differences between older adult users and nonusers of online health information. Findings suggest strategies for reducing this divide and implications for health education programs to promote HIT use among older adults.
