Asthma control and associated risk factors among adults with current asthma: Findings from 2019 behavioral risk factor surveillance system asthma call-back survey.

BACKGROUND: Despite the availability of effective treatments, many adults with asthma have uncontrolled asthma. Uncontrolled asthma can lead to severe exacerbations. This study aimed to determine the prevalence and predictors of uncontrolled asthma among adults (≥18 years) with current asthma in the United States. METHODS: We analyzed the 2019 Behavior Risk Factor Surveillance System Asthma Call-Back Survey data from 27 states. Asthma control status was classified as "well-controlled" or "uncontrolled" according to the National Asthma Education and Prevention guidelines. The study population consisted of 7937 adults (weighted n = 13,793,220) with current asthma. We used multivariable logistic regression models to identify predictors of uncontrolled asthma. RESULTS: Overall, 62 % of adults with asthma reported having uncontrolled asthma, and 26 % had emergency or urgent care visits or hospitalizations in the past year. Potentially modifiable risk factors associated with uncontrolled asthma included cost barriers to asthma-related healthcare (OR = 2.94; 95%CI 1.96-4.40), complementary and alternative medicine use (OR = 1.84; 95%CI 1.45-2.32), current smoking (OR = 2.25; 95%CI 1.48-3.44), obesity (OR = 1.39; 95%CI 1.02-1.89), COPD (OR = 1.98; 95%CI 1.43-2.74), depression (OR = 1.47; 95%CI 1.16-1.88), fair/poor general health (OR = 1.54; 95%CI 1.14-2.07), household income <$15,000 (OR = 2.59; 95%CI 1.42-4.71), and less than high school education (OR = 2.59; 95%CI 1.42-4.71). Non-modifiable risk factor was Hispanic ethnicity (OR = 1.73; 95%CI 1.09-2.73). CONCLUSION: Our findings suggest that uncontrolled asthma is common among adults and can be impacted by several factors. Effective asthma control programs are needed to improve asthma management and reduce unnecessary healthcare utilization.

A nationwide survey exploring physicians' and pharmacists' knowledge, awareness and perceptions regarding generic medicines in China.

BACKGROUND: Generic medicines substitution is an important means to control rapid growth of pharmaceutical expenditures for the healthcare system in China. Acceptance and utilization of generic medicines is highly influenced by healthcare providers' perceptions. This study aimed to compare the knowledge, awareness and perceptions of generic medicines between physicians and pharmacists in China. METHODS: We used an online, cross-sectional survey across China. The questionnaire explored four sections: demographic characteristics, assessment of the participants' knowledge and awareness of generic medicines, perceptions of generic medicines and generic substitution practices. Chi-square or Mann-Whitney-U tests were applied to compare differences between physicians and pharmacists. P-values < 0.05 were considered significant. RESULTS: A total of 1644 physicians and 4187 pharmacists participated. Most physicians (82.8%, n = 1362) and pharmacists (89.8%, n = 3760) correctly identified the definition of generic medicines. A similar percentage of physicians and pharmacists agreed that approved generic medicines are as effective (64.1% vs 68.2%) or safe (63.8% vs 69.1%) as brand-name medicines. Most physicians and pharmacists (67.6% vs 71.0%) supported the policy of generic substitution. In practice, 79.4% (n = 1305) of physicians reported that they had prescribed generic medicines. More than 78% of respondents reported an obvious increase in the number of generic medicines prescribed in their medical institutions. The majority of physicians and pharmacists identified lack of trust regarding efficacy and safety of generic medicines and the difficulty of changing patients' preference as top challenges in generic substitution. CONCLUSIONS: Both physicians and pharmacists surveyed had adequate knowledge of generic medicines, and hold positive attitude towards generics and generic substitution. Efficacy and safety are key factors related to prescribing or dispensing generic medicines. Various policies and regulations should be taken to encourage successful generic substitution.

Knowledge, perceptions and practices of pharmacists regarding generic substitution in China: a cross-sectional study.

OBJECTIVE: To evaluate pharmacists' knowledge, perceptions and practices towards generic substitution in the 11 pilot locations in China. DESIGN: An online cross-sectional survey using questionnaires was conducted. A convenience sampling technique was implemented to recruit pharmacists. SETTING AND PARTICIPANTS: The study took place in medical institutions of 11 pilot locations that participated in the pilot national centralised procurement programme in 2019. Two thousand two hundred and ninety-one pharmacists including hospital pharmacists or community pharmacists based on health-systems or clinics participated in the study. RESULTS: Most of the participants had the good knowledge of requirements for evaluating the quality and efficacy of generic drugs (n=2118; 92.4%), and the definition of generic drugs (n=2078; 90.7%). In terms of perceptions, 67.3% of respondents were of the opinion that generic drugs are equally as effective as the brand-name drugs, and 69.0% of respondents were of the opinion that generic drugs are as safe as brand equivalents. A high percentage of participants supported the policy of generic substitution (n=1634; 71.4%). A significant positive correlation was demonstrated between total knowledge score and total perception score (ρ=0.267; p<0.001). Efficacy, safety and the direction of national policies and hospital regulations were the main factors affecting pharmacists' willingness to dispense generic drugs. CONCLUSIONS: The study identified gaps in respondents' knowledge and perceptions of generic substitution. Pharmacists who are more knowledgeable in generic drugs tend to hold a more supportive attitude towards generic substitution. Although it appeared that pharmacists in China have largely accepted generic substitution, they still have concerns regarding the reliability and quality of generic drugs. The current issues need to be addressed for the realisation of the true value of generic drugs as part of the country's healthcare cost-containment strategy as well as the implementation of generic substitution policy in China.

Assessment of early COVID-19 compliance to and challenges with public health and social prevention measures in the Kingdom of Eswatini, using an online survey.

Public health and social measures have been implemented around the world in a bid to prevent the spread of COVID-19. Public compliance with these measures is key in successfully controlling the pandemic. This online survey assessed the compliance and attitude of adults residing in the southern African Kingdom of Eswatini to government protection, activity and travel measures aimed at controlling the spread of COVID-19. A rapid online survey, comprising of 28 questions, was administered in May 2020. More than 90% of respondents knew the virus could kill anyone and most respondents (70%) reported to be compliant to public health and social measures. Females, those who did not use public transport and those aged 30 years and above were significantly (p<0.01) more compliant, particularly to protective and travel measures. Social media, television and official government websites were the primary source of ongoing COVID-19 information for respondents of this online survey, and these methods should continue to be employed to reach the public who regularly use the internet. More than half of essential workers who responded to the online survey reported to have their own personal protective equipment; however, 32% either did not have any protective equipment or shared their equipment with other staff members. Due to the survey being online, these results should not be generalised to populations of low socioeconomic status.

An ethics-based approach to global health research part 1: Building partnerships in global health.

Global health partnerships (GHPs) can be the cornerstone for advancing research and public health. The steps to build a global research partnership focus on sharing a common research agenda, identifying key partners in the community, and establishing goals and expectations for partnerships. Moreover, upholding important values, such as communication, trust, and transparency is essential for building successful partnerships. Ethical dilemmas can propose challenges to researchers in global health. These challenges can be overcome by creating a shared vision for a research agenda, maintaining communication, and providing bidirectional training.

An Ethics-based Approach to Global Health Research Part 2: Strategies for Overcoming Logistic and Implementation Challenges.

With the growth of global pharmacy partnerships and collaborative research, particularly between high-income countries and low- or middle-income countries, it is necessary to establish best practices for fair and ethical collaboration and research. There is a gap in the pharmacy literature in this regard. Through this commentary, authors will present a pathway for future global health researchers including generating ideas based on mutual needs of the partnership and the community; exploring the importance of regulations including the need to conduct research and partnership projects within the confines of each participant's professional scope of practice, expertise, and licensure; describing the need to develop agreements and the components that should be included in such an agreement; discussing ethical guidelines for research planning, obtaining ethical approval, and planning for adverse events; and illustrating ethical considerations for research implementation with considerations around consent, data collection, linking patients to care after the completion of the study, and dissemination. Global examples, with a pharmacy-specific approach where applicable, within each section highlight the importance of discussion and action around ethics and equity when pursuing collaborative research, recognizing that many of these situations involve difficult decisions.

The Revolving Fund Pharmacy Model: backing up the Ministry of Health supply chain in western Kenya.

OBJECTIVES: A pressing challenge in low and middle-income countries (LMIC) is inadequate access to essential medicines, especially for chronic diseases. The Revolving Fund Pharmacy (RFP) model is an initiative to provide high-quality medications consistently to patients, using revenues generated from the sale of medications to sustainably resupply medications. This article describes the utilization of RFPs developed by the Academic Model Providing Access to Healthcare (AMPATH) with the aim of stimulating the implementation of similar models elsewhere to ensure sustainable access to quality and affordable medications in similar LMIC settings. METHODS: The service evaluation of three pilot RFPs started between April 2011 and January 2012 in select government facilities is described. The evaluation assessed cross-sectional availability of essential medicines before and after implementation of the RFPs, number of patient encounters and the impact of community awareness activities. FINDINGS: Availability of essential medicines in the three pilot RFPs increased from 40%, 36% and <10% to 90%, 94% and 91% respectively. After the first year of operation, the pilot RFPs had a total of 33 714 patient encounters. As of February 2014, almost 3 years after starting up the first RFP, the RFPs had a total of 115 991 patient encounters. In the Eldoret RFP, community awareness activities led to a 51% increase in sales. CONCLUSIONS: With proper oversight and stakeholder involvement, this model is a potential solution to improve availability of essential medicines in LMICs. These pilots exemplify the feasibility of implementing and scaling up this model in other locations.

Building Sustainable Capacity for Cardiovascular Care at a Public Hospital in Western Kenya.

Cardiovascular disease deaths are increasing in low- and middle-income countries and are exacerbated by health care systems that are ill-equipped to manage chronic diseases. Global health partnerships, which have stemmed the tide of infectious diseases in low- and middle-income countries, can be similarly applied to address cardiovascular diseases. In this review, we present the experiences of an academic partnership between North American and Kenyan medical centers to improve cardiovascular health in a national public referral hospital. We highlight our stepwise approach to developing sustainable cardiovascular services using the health system strengthening World Health Organization Framework for Action. The building blocks of this framework (leadership and governance, health workforce, health service delivery, health financing, access to essential medicines, and health information system) guided our comprehensive and sustainable approach to delivering subspecialty care in a resource-limited setting. Our experiences may guide the development of similar collaborations in other settings.

Effects of bovine lactoferrin on the immune system and the intestinal microflora of adult dogs.

Eighteen Beagle dogs were used to evaluate the effects of bovine lactoferrin (bLF) on immune function and faecal microbial populations. The study comprised three feeding periods, each lasting four weeks. After an initial control Period 1, six dogs per group were supplemented with 0, 120 and 1800 mg bLF/kg dry diet, respectively (Period 2). In Period 3 dogs received again control diets. Peripheral blood mononuclear cell subsets, lymphocyte proliferative response to concanavalin A, phytohaemagglutinin and pokeweed mitogen and plasma IgA and IgG concentrations were analysed. The faecal concentrations of aerobic and anaerobic bacteria, Escherichia coli, Clostridium perfringens, Lactobacillus spp. and Bifidobacterium spp. were determined by cultural methods. Supplementation of bLF increased the number of monocytes, T cells and cytotoxic T cells in the blood and the proliferative response of peripheral blood mononuclear cells. The leukocyte counts were not affected, except monocytes that increased after the supplementation with bLF. Plasma immunoglobulin concentrations were unchanged by treatment. Dogs supplemented with bLF tended to have lower faecal concentrations of E. coli and Clostridium perfringens. In conclusion, bLF seems to alter indices of the cellular immune response and faecal microbial populations of healthy adult dogs.
