Primary Care Providers' Information Needs for Prescribing Adolescents HIV Pre-Exposure Prophylaxis.

Although knowledge is a salient determinant in primary care providers (PCPs) prescribing HIV pre-exposure prophylaxis (PrEP) to adolescents, we know little about what information PCPs want about PrEP. We conducted an online mixed-method study to explore the PrEP information needs of a national sample of 351 PCPs. We analyzed data with deductive content analysis and compared themes between respondents who were aware and not aware of PrEP, knowledgeable and not knowledgeable of the prescribing guidelines, and prescribed and never prescribed PrEP to an adolescent. PCPs who were unknowledgeable about PrEP and never prescribed PrEP to an adolescent mentioned manufacturing information, indications and dosing, and contraindications and adverse reactions more so than PCPs who were aware of and prescribed PrEP. A better understanding of the information needs of PCPs could inform provider education interventions. Future research must examine the facilitators and barriers to integrating PrEP information into medical education and clinical settings.

An Exploratory Study of the PrEP Modality Preferences Among a Convenience Sample of Parents of Sexual and Gender Minority Adolescents.

PURPOSE: Parents' attitudes toward contraceptive delivery methods have been shown to impact their adolescents' use of contraceptive methods. However, little is known about the HIV pre-exposure prophylaxis (PrEP) delivery method attitudes of parents of sexual and gender minority (SGM) adolescents assigned male at birth (AMAB). This exploratory, mixed-method formative study examined the PrEP delivery method preferences among a convenience sample of 33 parents of SGM adolescents AMAB who live in Texas. METHODS: Participants completed an online survey, where they selected their preferred PrEP method for their SGM adolescent AMAB to use: PrEP as a daily oral pill, a bimonthly injectable, or a yearly implant. Parents answered an open-ended question about their reasons for choosing their preferred method. We analyzed data through descriptive statistics and inductive content analysis. RESULTS: Findings from this convenience sample suggest that there is not one PrEP delivery method that parents of SGM adolescents AMAB prefer: one third of parents (33.3%) selected PrEP as a daily oral pill, 45.5% selected PrEP as a bimonthly injectable, and 21.2% selected PrEP as an annual implant. Parents cited multiple reasons for selecting a delivery method over another, with the most prevalent reasons being adherence (57.6%), access or cost (21.2%), and generic convenience or ease (21.2%). DISCUSSION: Findings from this formative exploratory study sets the stage for future research and intervention development in increasing parental knowledge, preferences, and preference motivations for PrEP delivery methods.

Implementation Factors Associated With Primary Care Providers' Intention to Prescribe HIV PrEP to Adolescents in the United States.

PURPOSE: In the United States, adolescents (those 13-18 years old) are a key age group of those at risk for and affected by HIV. Although HIV pre-exposure prophylaxis (PrEP), one promising HIV prevention tool, is approved for eligible adolescents to use, adolescent access to PrEP is limited by primary care providers' (PCPs) willingness to prescribe it. This study examined which Theoretical Domains Framework factors are associated with PCPs' intention to prescribe PrEP to sexually active adolescents. METHODS: A total of 770 licensed PCPs practicing family medicine, internal medicine, or pediatrics in the United States completed an online cross-sectional questionnaire. Participants were recruited through a Qualtrics panel. We used a hierarchical regression to assess the association of demographic characteristics, sexual health care practices, and the 10 Theoretical Domains Framework factors with intention to prescribe PrEP to sexually active adolescents aged 13-18 years old. RESULTS: Although nearly all PCPs had heard about PrEP (90.9%), 30.6% ever prescribed PrEP to an adolescent. Intention to prescribe PrEP to sexually active adolescents was associated with seven out of the 10 Theoretical Domains Framework factors: knowledge, skills, professional role, belief capacity, belief consequence, environmental resource, social influence, and emotion. DISCUSSION: Our findings demonstrate that the Theoretical Domains Framework can be employed to understand the intrapersonal, interpersonal, and environmental factors associated with PCPs' intention to prescribe sexually active adolescents PrEP. Implementation strategies are needed to implement interventions that improve provider knowledge, attitudes, and skills related to prescribing PrEP to eligible adolescents.

Parental Concerns of Their Sexual and Gender Minority Adolescents Using HIV Pre-Exposure Prophylaxis.

Although parents of sexual and gender minority (SGM) adolescents are key stakeholders in SGM adolescents using HIV pre-exposure prophylaxis (PrEP), there is limited understanding of parental concerns and attitudes about their SGM adolescents taking PrEP. Fifty-four parents in the West South Central region of the U.S. completed an online, mixed-method, cross-sectional questionnaire to explore their concerns and questions about PrEP. Quantitative and qualitative results show that participants were more concerned about side effects, drug interactions, (non)adherence, and eligibility and duration of PrEP. Parents are less worried about picking PrEP from a pharmacy or returning to follow-up lab testing every three months. Most parents reported receiving medication information their adolescent takes from a medical provider and the media. Findings from this study can inform the development of parent-based PrEP interventions. Without further parent-based research and programming, SGM adolescents may continue to be disproportionately affected by HIV.

Effect of text message communication on patient presentation for an influenza vaccination in a community-based pharmacy setting.

BACKGROUND: Community pharmacies use text message communications for information regarding approaching refills and fill status. Patients can also be notified regarding annual influenza vaccine availability and schedule an appointment for the vaccine. OBJECTIVES: This study aimed to evaluate whether text message communications affected patient presentation and resulted in a percent increase of patients receiving an influenza vaccine compared with previous vaccine season and to determine whether additional vaccines are administered upon presentation. METHODS: Ambidirectional study retrospectively analyzed the impact, nationally, of a new text message communication on influenza vaccinations at a large community pharmacy chain and prospectively surveyed patients receiving an influenza vaccine at 2 geographically similar pharmacies of the chain in Southwest Virginia. Text message communications regarding vaccine and appointment availability were sent to patients at the age of 18 years and older who opted in to text message communications and received an influenza vaccine with the chain during the 2019-2020 influenza season. Vaccine data from consecutive seasons were compared. Eligible patients in Southwest Virginia were surveyed about how they were informed about availability, previous intent to receive an influenza vaccine, applicability to other vaccines, and effect of the coronavirus disease 2019 pandemic on vaccination. Results were analyzed using bivariate and multivariate analyses. RESULTS: Nationally, influenza vaccines administered increased by 17.45% in patients who permitted text message communication and overall by 13.22% after implementation. Decreases in co-administered pneumococcal vaccines and tetanus, diphtheria, and pertussis vaccines and an increase in co-administered zoster vaccines were observed. A total of 111 patients were surveyed; 4% presented owing to text message communication. A majority were intent on receiving the vaccine before being notified and reported that the pandemic did not affect presentation. Notably, 45.05% of patients were likely to receive routine vaccines if notified by text message. CONCLUSION: Text message communications are another viable way to increase vaccinations, but further studies should be conducted outside of a pandemic setting.

Racial/Ethnic Differences in Chronic Disease Predictors Among American High School Students.

BACKGROUND: Few studies have attempted to define clusters of chronic disease predictors with additional focus on racial/ethnic differences. The purpose of this study was to highlight differences in predictors of chronic diseases among American high school students by identifying subgroups using latent class analysis (LCA). METHODS: The chronic disease predictor variable used in the analysis was created from 5 modified items in the 2019 Youth Risk Behavior Surveillance that were identified to be critical to healthy lifestyles in Healthy People 2020. Descriptive, bivariate, multinomial logistic regression and LCA were performed using SAS 9.4 and Mplus in 9th to 12th grade students, using data from the Youth Risk Behavior Survey (N = 13,677). RESULTS: Three distinct classes emerged for US high school students and were characterized as high, moderate, and low risk of chronic disease (38%, 33%, and 29%, respectively). Black and Asian students had a higher chance of being in the high-risk class of chronic diseases. IMPLICATIONS FOR SCHOOL HEALTH POLICY, PRACTICE, AND EQUITY: Emphasis should be placed on sociocultural and socio-environmentally structured prevention programs for at risk/students, ensuring that policy formation reflects the language, identity, and needs of the populations at risk. CONCLUSIONS: The behavioral similarities of the classes identified highlight the need for continued research, novel interventions, and culturally sensitive strategies and policies in US high schools.

Impact of pharmacist counseling to enhance the accessibility of naloxone nasal spray to patients in a community pharmacy setting.

BACKGROUND: The Centers for Disease Control and Prevention guidelines recommend naloxone for every high-dose opioid prescription; in 2018, only 1 naloxone prescription was dispensed for every 69 high-dose opioid prescriptions. In Virginia, strategies for creating awareness and availability include the REVIVE! training and the standing protocol for pharmacists to dispense naloxone. OBJECTIVES: To evaluate if a proactive offer for counseling by pharmacists improves the percent change of patients who receive a prescription for naloxone nasal spray compared with the previous year's naloxone nasal spray fill history and to determine if the pharmacist's counseling affects a patient's confidence with opioid overdose and naloxone use. METHODS: Prospective 4-month, interventional study in southwest Virginia conducted at 5 geographically similar large community chain pharmacies. A National Drug Code activity report within each store was used to identify patients, aged 18-64 years, filling opioid medication without naloxone. A pharmacist recommended naloxone to patients at the point of care. Patients accepting the recommendation for naloxone received pharmacist counseling from a standardized counseling script and by using a naloxone nasal spray demo kit. All eligible patients were provided a postintervention survey assessing their confidence with naloxone, if naloxone had been recommended before, and if they were picking up naloxone on the basis of the pharmacist's recommendation. Results were analyzed using univariate and bivariate analyses. RESULTS: A total of 121 naloxone prescriptions were dispensed; an increase of 36% compared with the same period during the previous year. In total, 38 patients completed the postintervention survey. After receiving pharmacist counseling, patients indicated being very confident with administering naloxone correctly and for recognizing an opioid overdose, 73.9% and 65.2%, respectively. Of the patients who completed the survey, 60.5% received naloxone and accepted counseling from the pharmacist. CONCLUSION: After pharmacist counseling, naloxone dispensing increased, and patients were confident with both administration and recognition.

Impact of Adherence Education and Monitoring on Community Pharmacy Performance Scores and Patient Satisfaction.

BACKGROUND: Adherence, specifically to noninsulin diabetes medications, statins, and renin-angiotensin system antagonists (i.e. angiotensin-converting-enzyme inhibitors (ACEi), angiotensin II receptor blockers (ARBs), and aliskiren), is a measure tracked by the Centers for Medicare and Medicaid Services (CMS) to give Medicare Part D plans a star rating; pharmacies are impacted by these star ratings. The pharmacy is given a performance score based on the measure. Some pharmacies use a performance information management platform (PIMP) that allows pharmacies to better understand performance information to impact patient care. OBJECTIVES: (1) To evaluate if a monthly adherence monitoring and education service impacts the percentage of patientsadherent determined by pharmacy performance scores; (2) To determine patient satisfaction with the service in a large community pharmacy chain. METHODS: A six-month prospective interventional pilot study including patients with a proportion of days covered (PDC) of less than 80% for oral diabetes or renin-angiotensin system antagonists (RASA) medications was conducted in two pharmacies of a large community pharmacy chain in Southwest Virginia. Using pharmacy internal data analytics and PIMP data, the percentage of patients who are adherent to oral diabetes or RASA medications was determined including the baseline PDC for each patient. At the start of the study, the standard of care in this large community chain pharmacy was to address adherence, follow-up in one month and every three months thereafter. In this study, pharmacists provided monthly telephonic adherence monitoring and education for a six-month period. Each session was scripted for medication adherence history, education and data collection. The pharmacist provided guidance and counseling based on how the patient answered the questions. Pharmacists gathered information about adherence patterns and behaviors using a 14 item Likert-scale and multiple choice-based questionnaire during the first session. After completion of the final adherence monitoring and education session, pharmacists gathered patient satisfaction information using an eight item Likert-scale questionnaire. At the end of the six-month period, using PIMP data, the percentage of patients adherent to oral diabetes or RASA medications was determined based on pharmacy performance scores. The data was analyzed using uni-variate and bi-variate statistics to determine if there was a difference in pharmacy performance scores from the pre-study analysis. The adherence patterns and behaviors, as well as patient satisfaction with the program was evaluated to determine factors influencing nonadherence. RESULTS: A total of 55 patients were identified in two pharmacies, ten of which were excluded or declined involvement, leaving 45 enrolled in the adherence monitoring and education service. Of the 45 enrolled patients, ten completed the adherence patterns and behaviors questionnaire. About half of the patients were men (50.95%) with an average age of 71.17 years and taking an average of 6.55 prescription medications. All patients had Medicare Part D insurance and majority had a yearly income of less than $40,000. The average baseline PDC was 68.92. In pharmacy 1, the average performance score for oral diabetes medications trended down and the average performance score for hypertension medications trended up over the study period. In pharmacy 2, the average performance score for oral diabetes medications trended up and the average performance score in hypertension medications trended up over the study period. The adherence patterns and behaviors questionnaire revealed the majority of patients rarely forgot to take medications or run out of medications. Additionally, cost of medications did not seem to impact adherence and majority of patients knew the names and indications of their medications. Only one patient completed the patient satisfaction survey. CONCLUSIONS: An adherence monitoring and education service had mixed results in improving patient adherence and pharmacy performance scores. Only one patient completed the satisfaction survey, thus no conclusions can be made regarding patient satisfaction of the program. More research needs to be done regarding telephonic adherence programs.

Impact of Live Training on Medication Errors in a Community-Based Pharmacy Setting.

OBJECTIVE: To compare community-based pharmacy medication errors before and after a one-hour live interactive training session for both pharmacists and technicians. METHODS: A one group pre-post intervention design study was conducted in 20 community-based pharmacies in a district of a large national community pharmacy chain. A one-hour live, interactive session was developed based on incident reports and medication error trends including medication error definition, ways in which medication errors occur, strategies for mitigating errors, information about human error, and methods and habits to improve patient safety. At least 50% of full-time staff for each of the 20 pharmacies were required to attend a training session between December 1, 2017-January 15, 2018. Participants completed a demographics survey documenting gender, age, credentials, number of years of experience, and years of service with the company. Pharmacies were categorized as low, medium or high volume based on prescription count. Medication errors were compared six months pre- and post-live education session. Data were analyzed using SAS version 9.4. RESULTS: One hundred and thirty- five errors and 111 errors were reported pre-and post-live training (mean 6.85 and 5.55, p < 0.301), respectively. Nine pharmacies were low, eight medium, and three high volume with the mean number of medication errors reported pre- and post-live training; low 4.33 vs 4.11 p<0.478, medium 9.37 vs 6.87 p<0.443, and high 7.66 vs 6.33 p<0.593, respectively. Sixty pharmacy staff (34 pharmacists, 26 technicians) attended one of the live training sessions; 73% female; most frequently reported age range 35-50 years; 23 Doctor of Pharmacy, 11 Bachelor of Science in Pharmacy, and 26 Certified Technician; and average number of years' experience was 13.6 and average service with the company was 8.6 years. CONCLUSIONS: A live training session for both pharmacists and technicians did not significantly decrease medication errors, but could be incorporated as an element of a medication safety program. It should be considered for implementation in other districts of this large national pharmacy chain as a part of an improved patient safety effort.

Kinetic and spectroscopic studies of bicupin oxalate oxidase and putative active site mutants.

Ceriporiopsis subvermispora oxalate oxidase (CsOxOx) is the first bicupin enzyme identified that catalyzes manganese-dependent oxidation of oxalate. In previous work, we have shown that the dominant contribution to catalysis comes from the monoprotonated form of oxalate binding to a form of the enzyme in which an active site carboxylic acid residue must be unprotonated. CsOxOx shares greatest sequence homology with bicupin microbial oxalate decarboxylases (OxDC) and the 241-244DASN region of the N-terminal Mn binding domain of CsOxOx is analogous to the lid region of OxDC that has been shown to determine reaction specificity. We have prepared a series of CsOxOx mutants to probe this region and to identify the carboxylate residue implicated in catalysis. The pH profile of the D241A CsOxOx mutant suggests that the protonation state of aspartic acid 241 is mechanistically significant and that catalysis takes place at the N-terminal Mn binding site. The observation that the D241S CsOxOx mutation eliminates Mn binding to both the N- and C- terminal Mn binding sites suggests that both sites must be intact for Mn incorporation into either site. The introduction of a proton donor into the N-terminal Mn binding site (CsOxOx A242E mutant) does not affect reaction specificity. Mutation of conserved arginine residues further support that catalysis takes place at the N-terminal Mn binding site and that both sites must be intact for Mn incorporation into either site.
