BACKGROUND Front‐line staff at blood collection organizations (BCOs) play important roles in keeping the blood supply safe, yet research on their professional practice and perspectives on training needs is sparse. This qualitative study explored these topics with regard to the then‐impending change in donor eligibility for men reporting sex with another man (MSM). STUDY DESIGN AND METHODS Semistructured, individual interviews with BCO staff (n = 13) in Northern California covered experiences of and opinions on indefinite deferral, the revised 1‐year deferral, and anticipated potential challenges arising from the new policy. Transcripts were thematically coded, using deductive and inductive approaches. Analysis identified recurrent and divergent themes. RESULTS Interviewees reported strong values of professionalism and respect for donors and supported the change to a 1‐year deferral for MSM donors. Nonetheless, nearly all voiced the need for more in‐depth training to maximize the likelihood of successful implementation. Specific recommendations included the use of role‐play, provision of science‐based talking points or FAQs, and empathy for donors and staff. CONCLUSION More than the usual training may be required to help BCO staff feel prepared to educate the public about changes to MSM‐related deferrals and communicate effectively with donors about potentially deferrable behavior. Overall, these findings suggest that before future policy changes, BCO staff's opinions about and role in implementing new donor eligibility screening procedures merit consideration.

Smoke-free policies prevent exposure to secondhand smoke and encourage tobacco cessation. Local smoke-free policies that are more comprehensive than statewide policies are not allowed in states with preemption, including Oklahoma, which has the sixth highest smoking prevalence in the United States. In states with preemption, voluntary smoke-free measures are encouraged, but little research exists on venue owners’ and managers’ views of such measures, particularly in nightlife businesses such as bars and nightclubs. This article draws from semistructured interviews with 23 Oklahoma bar owners and managers, examining perceived risks and benefits of adopting voluntary smoke-free measures in their venues. No respondents expressed awareness of preemption. Many reported that smoke-free bars and nightclubs were an inevitable societal trend, particularly as younger customers increasingly expected smoke-free venues. Business benefits such as decreased operating and cleaning costs, improved atmosphere, and employee efficiency were more convincing than improved employee health. Concerns that voluntary measures created an uneven playing field among venues competing for customers formed a substantial barrier to voluntary measures. Other barriers included concerns about lost revenue and fear of disloyalty to customers, particularly older smokers. Addressing business benefits and a level playing field may increase support for voluntary smoke-free nightlife measures.

Medical Anthropology

Although pre-exposure prophylaxis (PrEP) has dramatically impacted HIV prevention, deep engagement with PrEP-takers’ own accounts of their sexual behavior is still rare. We report findings from semi-structured interviews with male participants of the US PrEP Demonstration Project. In their narratives, interviewees variously foregrounded their individual selves, interactions with sexual partners, and the biopolitical and historical context of their lives. PrEP served to discursively integrate the multiple selves populating these stories. We argue that medical anthropological notions can help make sense of men’s accounts, and PrEP’s role in them, advancing a holistic conception of personhood that includes but transcends concern with HIV.

Aims: To evaluate how young adults perceive and compare harms and benefits of marijuana and tobacco products in the context of a legal marijuana market in Colorado. Design: Semi-structured qualitative interviews. Setting: Denver, Colorado, USA. Participants: Thirty-two young adults (18-26 years old) who used tobacco/marijuana/vaporizers. Semi-structured interviews addressed perceived harms and benefits of various tobacco and marijuana products and personal experiences with these products. Findings: Young adults evaluated harms and benefits using five dimensions: (1) Combustion - smoking was considered more harmful than non-combustible products (e.g., e-cigarettes, vaporizers, and edibles); (2) Potency - edibles and marijuana concentrates were perceived as more harmful than smoking marijuana flower because of potential to receive too large a dose of THC (tetrahydrocannabinol); (3) Chemicals - products containing chemical additives were seen as more harmful than "pure" or "natural" plant products; (4) Addiction - participants recognized physiological addiction to nicotine, but primarily talked about psychological or lifestyle dependence on marijuana; (5) Source of knowledge - personal experiences, warning labels, campaigns, the media, and opinions of product retailers and medical practitioners affected perceptions of harms and benefits. Conclusions: Among young adults in Colorado, USA, perceived harms and benefits of tobacco and marijuana include multiple dimensions. Health educational campaigns could benefit from addressing these dimensions, such as the potency of nicotine and cannabis concentrates and harmful chemicals present in the organic material of tobacco and marijuana. Descriptors such as "natural" and "pure" in the promotion or packaging of tobacco and marijuana products might be misleading.

The objective of this study was to conduct focus groups with youth (18–29 years old) living with HIV (YLWH) to better understand preferences for mobile applications in general and to inform the design of a mobile health application aimed at improving retention and engagement in healthcare and adherence to antiretroviral therapy. We conducted four focus groups with YLWH to elicit the names and characteristics of applications that they commonly used, reasons they deleted applications, and the features of an ideal mobile health application. A diverse sample of youth (N = 17) with a mean age of 25 years, 88.2% male, and 29.4% African American participated in four focus groups. Positive attributes of applications included informative, simple, allowing for networking, timely updates, little overlap with other applications, unlimited access to entertainment, and with ongoing advancement. Participants identified several reasons for deleting applications, including engaging in excessive behaviors (e.g., spending money), for hook ups only, too many notifications or restrictions, occupied too much space on device, or required wireless connectivity or frequent updates. Participants suggested that a mobile health application that they would find useful should have the ability to connect to a community of other YLWH, readily access healthcare providers, track personal data and information (such as laboratory data), and obtain health news and education. Privacy was a key factor in a mobile health application for all participants. Researchers can use the information provided by focus group participants in creating mobile health applications for YLWH.

Background: Emergency Medical Service (EMS) providers are tasked with rapid evaluation, stabilization, recognition, and transport of acute stroke patients. Although prehospital stroke scales were developed to assist with stroke recognition, unrecognized challenges exist in the prehospital setting that hinder accurate assessment of stroke. The goal of this qualitative study was to systematically understand the challenges and barriers faced by paramedics in recognizing stroke presentations in the field. Methods: Paramedics from 12 EMS agencies serving a mix of rural, suburban, and urban communities in the State of California participated in five focus group discussions. Group size ranged from 3-8, with a total of 28 participants. Demographics of the participants were collected and focus group recordings were transcribed verbatim. Transcripts were subjected to deductive and inductive coding, which identified recurrent and divergent themes. Results: Strong consensus existed around constraints to prehospital stroke recognition; participants cited the diversity of stroke presentations, linguistic diversity, and exam confounded by alcohol and or drug use as barriers to initial evaluation. Also, lack of educational feedback from hospital staff and physicians and continuing medical education on stroke were reported as major deterrents to enhancing their diagnostic acumen. Across groups, participants reported attempting to foster relationships with hospital personnel to augment their educational needs, but this was easier for rural than urban providers. Conclusions: While challenges to stroke recognition in the field were slightly different for rural and urban EMS, participants concurred that timely, systematic feedback on individual patients and case-based training would strengthen early stroke recognition skills.

Tobacco Induced Diseases

Smokers over the age of 45 are the only group with an increase in smoking prevalence, are the least likely to quit smoking, and bear most of the burden of tobacco-related disease. Research characterizing older adult perceptions of warning labels and anti-tobacco messages has not been reported in the literature. The purpose of this study was to describe whether older smokers perceived warning labels and anti-tobacco messages as effective for the promotion of smoking cessation. A secondary aim was to explore what types of messages and message delivery formats are most relevant to older adult smokers. This focus group study is part of a larger study to characterize older smokers' perceptions of the risks and benefits associated with conventional and emerging tobacco products and determine the extent to which these perceptions relate to exposure to pro- and anti-tobacco messages. From April 2013 to August 2014 we conducted eight focus groups with 51 current and former smokers a focus group study in urban and suburban California. A semi-structured format about current use of conventional and emerging tobacco products was used. Participants were asked to recall and comment on examples of warning labels and anti-tobacco messages. Data were transcribed and thematically coded. Warning labels and anti-smoking messages were seen as ineffective for smoking cessation motivation among older California smokers. Positive framed anti-tobacco messages were identified as most effective. Text-only warnings were seen as ineffective due to desensitizing effects of repeated exposure. Negative messages were described as easy to ignore, and some trigger urges to smoke. Older adults are knowledgeable about the risks and health effects of smoking. However, they tend to be less knowledgeable about the benefits of cessation and may underestimate their ability to quit. These findings suggest that messages with a positive frame that outline immediate and long-term benefits of cessation would be an effective approach for long-term smokers. Current anti-tobacco messaging was generally not seen as effective for smoking cessation among long-term smokers.

Indefinite deferral from donation for any man who discloses having had sex with another man even once since 1977 (MSM77) is the US FDA's standing policy. This qualitative component of the Blood Donation Rules and Opinion Study was designed to provide insight into the perceptions and practices of current or previous donors with MSM history. Forty human immunodeficiency virus (HIV)-negative MSM completed an online survey, indicating that they had donated blood and were willing to be interviewed. Semistructured, individual interviews with these key informants covered donation experience and motivations, perceptions of MSM77, policy change preferences, and possible impact of a change to a time-limited deferral. Transcripts were coded deductively and inductively, following a modified Grounded Theory approach. Analysis identified recurrent and divergent themes. Ninety-five percent of participants endorsed modifying MSM77. Preferred deferral length ranged from none to 5 years; a common opinion was that a science-based deferral period would be less than 1 year. Other policy change recommendations included incorporating questions about specific HIV risk behaviors to the donor questionnaire for all potential donors. Interviewees recognized HIV infection rates are higher in MSM than the general US population, but participants considered themselves low-risk for HIV, donated blood "to save lives," and justified their recommendations as being more effective ways to identify donors at risk for HIV. Results suggest that MSM donors are concerned with blood safety; they can be appealed to as such. Communications about a new deferral policy should include scientific explanations and acknowledge altruistic motivations of potential donors. © 2015 AABB.

In the United States, any man who discloses having had sex with another man (MSM) even once since 1977 is currently deferred from donating blood. A study was conducted to assess noncompliance with the policy at four geographically dispersed blood centers. Male donors 18+ years of age with e-mail addresses were randomly selected and invited to complete a confidential online survey between August and October 2013. No additional recruitment e-mails were sent. Survey content included demographics, sexual history, donation history, compliance with the policy, and opinions about current and modified policies. Response rate was 11.5% but varied by center (6.3% to 21.7%). Of 3183 completed surveys, 2.6% of respondents (95% confidence interval, 2.1%-3.2%) reported donation after male-male sex. Noncompliance was not statistically different among the centers (p = 0.1), but was related to age with 5.7, 4.6, 2.5, and 1.0% of donors 18 to 24, 25 to 34, 35 to 54, and 50+ years of age, respectively, reporting noncompliance (p < 0.001). Of all respondents, 6.8% reported at least six female and 0.3% reported at least six male sex partners in the past 5 years. Opinions about the current MSM policy were mixed with noncomplying donors more supportive of change than complying donors. Approximatey half of noncompliers indicated they would adhere to a 1-year deferral. Noncompliance with the MSM policy is evident and may be increasing compared to earlier data. Any change from the current policy will require close monitoring to determine whether it affects residual risk of HIV in the US blood supply. © 2015 AABB.

To describe older smokers' perceptions of risks and use of e-cigarettes, and their responses to marketing and knowledge of, and opinions about, regulation of e-cigarettes. Eight 90-minute focus groups with 8 to 9 participants met in urban and suburban California to discuss topics related to cigarettes and alternative tobacco products. Older adults are using e-cigarettes for cessation and as a way to circumvent no-smoking policies; they have false perceptions about the effectiveness and safety of e-cigarettes. They perceive e-cigarette marketing as a way to renormalize smoking. To stem the current epidemic of nicotine addiction, the FDA must take immediate action because e-cigarette advertising promotes dual use and may contribute to the renormalization of smoking.
