RESUMO

BACKGROUND: Synthetic algal-fungal and algal-bacterial cultures have been investigated as a means to enhance the technological applications of the algae. This inclusion of other microbes has enhanced growth and improved stress tolerance of the algal culture. The goal of the current study was to investigate natural microbial consortia to gain an understanding of the occurrence and benefits of these associations in nature. The photosynthetic protist Euglena mutabilis is often found in association with other microbes in acidic environments with high heavy metal (HM) concentrations. This may suggest that microbial interactions are essential for the protist's ability to tolerate these extreme environments. Our study assessed the Cd tolerance of a natural fungal-algal-bacterial (FAB) association whereby the algae is E. mutabilis. RESULTS: This study provides the first assessment of antibiotic and antimycotic agents on an E. mutabilis culture. The results indicate that antibiotic and antimycotic applications significantly decreased the viability of E. mutabilis cells when they were also exposed to Cd. Similar antibiotic treatments of E. gracilis cultures had variable or non-significant impacts on Cd tolerance. E. gracilis also recovered better after pre-treatment with antibiotics and Cd than did E. mutabilis. The recoveries were assessed by heterotrophic growth without antibiotics or Cd. In contrast, both Euglena species displayed increased chlorophyll production upon Cd exposure. PacBio full-length amplicon sequencing and targeted Sanger sequencing identified the microbial species present in the E. mutabilis culture to be the fungus Talaromyces sp. and the bacterium Acidiphilium acidophilum. CONCLUSION: This study uncovers a possible fungal, algal, and bacterial relationship, what we refer to as a FAB consortium. The members of this consortium interact to enhance the response to Cd exposure. This results in a E. mutabilis culture that has a higher tolerance to Cd than the axenic E. gracilis. The description of this interaction provides a basis for explore the benefits of natural interactions. This will provide knowledge and direction for use when creating or maintaining FAB interactions for biotechnological purposes, including bioremediation.

RESUMO

OBJECTIVES: Obstructive sleep apnea (OSA) among veterans is frequently underdiagnosed and undertreated. The present study sought to: 1) characterize the prevalence and rate of treatment of OSA among VA users and non-users and 2) examine the associations between diagnosed or probable OSA and key physical and mental health outcomes. METHODS: Gulf-War I-era Veterans were recruited as part of a national survey assessing mental and physical health concerns, healthcare needs, and healthcare utilization. OSA diagnoses were self-reported while sleep apnea risk was assessed via the STOP-Bang. Veterans also completed questionnaires assessing overall health, pain, depression, PTSD, and psychosocial functioning. RESULTS: 1,153 veterans were included in the present analyses (Mean age = 58.81; 21.84% female). Compared to non-VA healthcare users, veterans receiving care at the VA were more likely to have been diagnosed with OSA (p < .001) and report receiving treatment for OSA (p = .005). Compared to veterans at low risk for OSA, veterans at elevated risk reported higher levels of pain (p = .001), depression (p = .02), and poorer psychosocial functioning (p < .001). CONCLUSIONS: OSA diagnoses appear to be more common among VA healthcare users. Findings suggest that OSA remains underdiagnosed and associated with important physical and mental health consequences. Additional screening for OSA, especially among non-VA clinics, is warranted.

RESUMO

BACKGROUND: Children with medical complexity (CMC) comprise < 1% of the pediatric population, but account for nearly one-third of healthcare expenditures. Further, while CMC account for up to 80% of pediatric inpatient hospital costs, only 2% of Medicaid spending is attributed to home healthcare. As a result, the current health system heavily relies on family caregivers to fill existing care gaps. This study aimed to: (1) examine factors associated with hospital admissions among CMC and (2) contextualize the potential for home nursing care to improve outcomes among CMC and their families in South Carolina (SC). METHODS: This mixed-methods study was conducted among CMC, their family caregivers, and physicians in SC. Electronic health records data from a primary care clinic within a large health system (7/1/2022-6/30/2023) was analyzed. Logistic regression examined factors associated with hospitalizations among CMC. In-depth interviews (N = 15) were conducted among physicians and caregivers of CMC statewide. Patient-level quantitative data is triangulated with conceptual findings from interviews. RESULTS: Overall, 39.87% of CMC experienced ≥ 1 hospitalization in the past 12 months. CMC with higher hospitalization risk were dependent on respiratory or neurological/neuromuscular medical devices, not non-Hispanic White, and demonstrated higher healthcare utilization. Interview findings contextualized efforts to reduce hospitalizations, and suggested adaptations related to capacity and willingness to provide complex care for CMC and their families. CONCLUSIONS: Findings may inform multi-level solutions for accessible, high-quality home nursing care among CMC and their families. Providers may learn from caregivers' insight to emphasize family-centered care practices, acknowledging time and financial constraints while optimizing the quality of medical care provided in the home.

RESUMO

In 2021, national leaders in the United States declared a "national youth mental health crisis." Still, only 1-in-4 children receive adequate mental healthcare access. Patient Navigator Programs (PNPs) can improve children's referral-to-connection to mental health services. We examined patient- and community-level factors associated with pediatric mental healthcare access. Pediatric Support Services (PSS) is a PNP that triages mental and behavioral health referrals within a large health system in a southeastern state. This study analyzes PSS data from September 2017-March 2023 and Child Opportunity Index 2.0 state-normed zip-code level data to assess social drivers of health estimates. Structural equation modeling was conducted between patient- and community-level factors and connection to mental health services. Overall, 62.7% of children connected to mental health services since PSS' inception. Regardless of SDOH, as children get older, they are more likely to connect with mental health services (ß = .053, SE = .010, p < .001). Children with greater number of referral needs are more likely to connect with mental health services (ß = .034, SE = .011, p = .002). Further, children who live in communities with higher opportunity levels are more likely to connect with mental health services (ß = .016, SE = .008, p = .040), suggesting that children who live in low-income communities experience more barriers to mental healthcare. Social drivers may inform referral practices and tiered navigation support for optimal mental healthcare access among children. Further research should demonstrate the effectiveness of PNPs integrated within healthcare and community-based settings.

RESUMO

BACKGROUND: Cognitive reserve (CR) is the ability to maintain cognitive performance despite brain pathology. CR is built through lifecourse experiences (e.g., education) and is a key construct in promoting healthy aging. However, the operationalization of CR and its estimated association with late-life cognition varies. The purpose of this study was to systematically examine the operationalization of CR and the relationship between its operationalization and late-life cognition. METHODS: We performed a comprehensive review of experiences (proxies) used to operationalize CR. The review informed quantitative analyses using data from 1366 participants of the Memory and Aging Project to examine 1) relationships between proxies and 2) the relationship between operationalization and late-life cognition. We also conducted a factor analysis with all identified CR experiences to create a composite lifecourse CR score. Generalized linear mixed models examined the relationship between operationalizations and global cognition, with secondary outcomes of five domains of cognition to examine consistency. RESULTS: Based on a review of 753 articles, we found the majority (92.3%) of the 28 commonly used proxies have weak to no correlation between one another. There was substantial variability in the association between operationalizations and late-life global cognition (median effect size: 0.99, IQR: 0.34 to 1.39). There was not strong consistency in the association between CR operationalizations and the five cognitive domains (mean consistency: 56.1%). The average estimate for the 28 operationalizations was 0.91 (SE = 0.48), compared to 2.48 (SE = 0.40) for the lifecourse score and it was associated with all five domains of cognition. CONCLUSIONS: Inconsistent methodology is theorized as a major limitation of CR research and barrier to identification of impactful experiences for healthy cognitive aging. Based on the weak associations, it is not surprising that the relationship between CR and late-life cognition is dependent on the experience used to operationalize CR. Scores using multiple experiences across the lifecourse may help overcome such limitations. Adherence to a lifecourse approach and collaborative movement towards a consensus operationalization of CR are imperative shifts in the study of CR that can better inform research on risk factors related to cognitive decline and ultimately aid in the promotion of healthy aging.

RESUMO

Approximately 1-in-5 children have a diagnosed mental, behavioral, and/or developmental disorder or delay by age 8 in the United States. Children with such conditions often require complex, complicated diagnostic and specialty care, making them susceptible to repeated referrals and ongoing unmet healthcare needs. Patient navigation programs (PNPs) are designed to integrate care from primary care providers to community-based services, using trained navigators to help patients and their families manage referrals and connect with referred services. This study examines factors associated with repeated referrals to an active PNP to inform ongoing referral patterns and adaptations to standard navigation support within a large healthcare system in South Carolina (SC). Data is sourced from the inception of the PNP in 2017 through 2022, including 15,702 referrals. Overall, 71.07% had no repeated referrals. Children who are older, diagnosed with attention deficit disorder(s), behavioral concerns, depression, multiple referral needs, and insured by Medicaid were found to be most susceptible to repeated referrals. Conversely, children who are non-Hispanic Black, were referred at a well-child visit, and are primarily insured by private insurance or Tricare were least likely to have repeated referrals. Children who are insured by Medicaid are more likely to be younger, identify as non-Hispanic Black, Hispanic, or another race/ethnicity, and have multiple needs at time of initial referral, identifying a potentially compounded risk for those who hold multiple risk factors to experiencing repeated referrals. Findings may inform adaptations to this PNP model to adjust navigator protocol for at-risk populations and equitably optimize referral-to-service connection.

RESUMO

Food insecurity is linked with poor physical and mental health outcomes, including anxiety, depression and stress. Rural residents in particular face unique challenges obtaining healthy food; the COVID-19 pandemic exacerbated the relationship between food insecurity and mental health outcomes. This study examines the relationship between food insecurity and stress, and the moderating influence of household characteristics, neighborhood social environment and food environment on this relationship, using a sample of 630 rural South Carolina (SC) residents during COVID-19. Two measures of stress were used in this study: current levels of stress and changes in stress since COVID-19. Results showed a gradient pattern between food insecurity and stress: rural residents with high food insecurity were 6.1 times more likely and those with moderate food insecurity were 3.4 times more likely to report higher level of general stress than those with low food insecurity; rural residents with high food insecurity were 3.3 times more likely and those with moderate food insecurity were 2.0 times more likely to report greater increase in stress after COVID-19 than those with low food insecurity. Neighborhood social environment and food environment provided a buffering effect on the relationship between food insecurity and stress. A stronger social environment after COVID-19 and higher levels of easiness in food access mitigated the negative impacts of food insecurity on stress. Efforts to ameliorate food insecurity should address these broader contextual variables, involving community-level factors.

RESUMO

In this study, we explored the relationship between the food environment and food security among rural adults during the COVID-19 pandemic. Researchers, with assistance from community partners, conducted a cross-sectional survey assessing the impact of COVID-19 on food access, food security, and physical activity in 9 rural South Carolina (SC) counties. This survey was administered to a purposive sample (N = 587) from August 2020 to March 2021. The dependent variable was a binary indicator of food insecurity (past 3 months), in accordance with the USDA Household Food Security Survey Module. Independent variables were sociodemographic characteristics, food environment factors (eg, shopping at grocery stores, partial markets, and farmers' markets), and shopping behaviors during the pandemic. Overall, 31% of respondents were food insecure. Food security status differed by income and household composition. Results indicate that the odds of food insecurity were higher for respondents who shopped frequently at partial markets (adjusted odds ratio [AOR] = 1.61, 95% confidence interval [CI]: 1.01-2.56) and shopped more for food before the pandemic than during the pandemic (AOR = 1.68, 95% CI: 1.07-2.64). Findings underscore the importance of examining the relationship between the food environment and food insecurity during COVID-19 in rural settings.

RESUMO

INTRODUCTION: An intersectionality framework recognizes individuals as simultaneously inhabiting multiple intersecting social identities embedded within systems of disadvantage and privilege. Previous research links perceived discrimination with worsened health outcomes yet is limited by a focus on racial discrimination in isolation. We applied an intersectional approach to the study of discrimination to examine the association with adverse perinatal health outcomes. METHODS: We analyzed data from a cohort of 2,286 pregnant participants (Black, n = 933; Hispanic, n = 471; White, n = 853; and Other, n = 29) from the Centering and Racial Disparities trial. Perceived discrimination was assessed via the Everyday Discrimination Scale (EDS) and perinatal health outcomes collected via electronic medical record review. Latent class analysis was used to identify subgroups of discrimination based on EDS item response and the rate of adverse perinatal health outcomes compared between subgroups using a Bolck, Croon and Hagenaars 3-step approach. RESULTS: Four discrimination subgroups were identified: no discrimination, general discrimination, discrimination attributed to one or several social identities, and discrimination attributed to most or all social identities. Experiencing general discrimination was associated with postpartum depression symptoms when compared with experiencing no discrimination among Black (9% vs 5%, P = .04) and White participants (18% vs 9%, P = .01). White participants experiencing general discrimination gave birth to low birthweight infants at a higher rate than those experiencing no discrimination (11% vs 6%, P = .04). No significant subgroup differences were observed among Hispanic participants. CONCLUSION: Perceived discrimination may play an influential role in shaping perinatal health. More research applying an intersectional lens to the study of discrimination and perinatal health outcomes is needed.

RESUMO

OBJECTIVES: We had two objectives: (1) to investigate differences in tear film and blink parameters in patients with six ocular surface diseases (OSD): ocular graft versus host disease (oGVHD), Stevens-Johnson syndrome (SJS), lax eyelid syndrome, meibomian gland dysfunction (MGD), obstructive sleep apnea, and dry eye disease; and (2) to characterize the relationships between lipid layer thickness (LLT), meiboscore, Schirmer I test, and three blink parameters: partial blink rate (PBR), interblink interval (IBI), and interpalpebral fissure height (IPFH) in this group of patients. METHODS: This is a single-site retrospective analysis of 228 patients (456 eyes) with six different primary OSD at Loyola University Medical Center between January 2018 and July 2020. Objective parameters included: LLT, IBI, PBR, IPFH, Pult meiboscore, and Schirmer I score. Linear mixed effects models were used to analyze the relationships between these parameters. RESULTS: The meiboscore was highest in patients with SJS compared with the other five groups. There was significant variability in IPFH across different groups, with patients with oGVHD having the smallest height. An increase in IPFH was associated with increases in IBI, PBR, and Schirmer score. Patients with no partial blinks demonstrated a statistically significant higher IBI than patients who showed 1%-50% partial blinks. Finally, no statistically significant relationship was found between the following: (1) meiboscore and LLT, (2) OSDI and IPFH, (3) Schirmer score and IBI, or (4) LLT and IBI. CONCLUSIONS: There were fewer than anticipated differences in objective tear film and blink parameters between patients with six different OSD. A statistically significant association was found between IPFH and Schirmer score and IPFH and IBI, representing new findings in tear film research. Further investigation of the relationship between IPFH and IBI is needed.

RESUMO

Cannabis use has been indicated as a risk factor for suicide in veterans. This study of Gulf War veterans tested the relationship between self-report past year cannabis use and (a) past year suicidal ideation and (b) risk for suicidal behavior. Data were from a national sample (N = 1126) of Gulf War veterans. Logistic regression models indicated cannabis use was associated with past year suicidal ideation and elevated risk for suicidal behavior, independent of key covariates. In corroboration with research on other military populations, this study indicates a potentially concerning association between cannabis use and suicide risk in Gulf War veterans.

RESUMO

Bystander interventions (BIs) primarily focus on increasing a sense of community and responsibility among students. This study examined moral norms as a determinant of intentions towards BI, within the Theory of Planned Behavior (TPB). College students at two universities (n = 291) completed an online survey measuring TPB constructs (e.g., intentions, perceived norms) and moral norms. Results indicated that moral norms were significantly associated with intentions toward BI, and appeared to be a valuable addition to the overall perceived norms construct. In addition, the law, parents, peers, and religion were identified as significant determinants of moral norms. Promoting collective responsibility to engage in BI and including a moral imperative to act in message development could increase the impact of BI.

RESUMO

This work showcases chiral complementarity in aromatic stacking interactions as an effective tool to optimize the chiroptical and electrochemical properties of perylene diimides (PDIs). PDIs are a notable class of robust dye molecules and their rich photo- and electrochemistry and potential chirality make them ideal organic building blocks for chiral optoelectronic materials. By exploiting the new bay connectivity of twisted PDIs, a dynamic bis-PDI macrocycle (the "Pink Box") is realized in which homochiral PDI-PDI π-π stacking interactions are switched on exclusively. Using a range of experimental and computational techniques, we uncover three important implications of the macrocycle's chiral complementarity for PDI optoelectronics. First, the homochiral intramolecular π-π interactions anchor the twisted PDI units, yielding enantiomers with half-lives extended over 400-fold, from minutes to days (in solution) or years (in the solid state). Second, homochiral H-type aggregation affords the macrocycle red-shifted circularly polarized luminescence and one of the highest dissymmetry factors of any small organic molecule in solution (glum = 10-2 at 675 nm). Finally, excellent through-space PDI-PDI π-orbital overlap stabilizes PDI reduced states, akin to covalent functionalization with electron-withdrawing groups.

RESUMO

OBJECTIVE: Depression and chronic pain are major problems in American veterans, yet there is limited long-term research examining how they relate to one another in this population. This study examined the relationship between depressive symptoms and pain in U.S. veterans 50 years of age or older. METHODS: This study used data on veterans from the 2002-2016 waves of the Health and Retirement Study (n = 4,302), a large-scale observational study of Americans 50 years of age or older. Measures included a short form of the Center for Epidemiologic Studies Depression scale and two items assessing the presence and degree of pain. Analyses included random-intercept cross-lagged panel models (RI-CLPM). RESULTS: In the RI-CLPM, there were roughly equivalent cross-lagged effects between depressive symptoms and pain. There was also evidence that depressive symptoms and pain have a trait-like component and that these trait-like characteristics are associated. CONCLUSIONS: These findings indicate that depressive symptoms and pain in veterans are stable characteristics in American veterans 50 years of age or older. There appear to be reciprocal effects between the two, whereby deviations in one's typical depressive symptoms predict subsequent deviations in one's pain level and vice versa; however, the size of these effects is very small. These findings suggest that clinicians should treat both depressive symptoms and pain, rather than assume that treatment benefits in one domain will lead to major benefits in another.

RESUMO

The benefits of physical activity to health and obesity prevention are well established. However, attributes of the built environment influence participation in physical activity. The purpose of this study is to assess differences in perceptions of neighborhood walkability across demographic characteristics and social environment factors among rural residents. In a telephone survey, adult respondents (N = 448) across nine rural counties in a southeastern state answered questions about perceived neighborhood walkability, demographic characteristics, and their neighborhood social environment. Study recruitment for a convenience sample occurred through collaborations with local community organizations. Prevalence of destinations and barriers were estimated according to demographic and neighborhood social environment characteristics. Multiple logistic regression models assessed the association of demographic and neighborhood social environment characteristics with neighborhood walkability and calculated adjusted prevalence. Relaxing places to walk were the most often reported destinations (62.0%), followed by retail destinations (45.7%), and communal destinations (42.6%). Traffic was the most reported barrier to safe walking (40.4%), followed by animals (37.5%), and crime (30.5%). Perceptions of retail and communal destinations varied by age and race. Perceptions of traffic and crime as barriers varied by race, weight status, and income. Community belonging and social cohesion were associated with lower perceptions of barriers. Study findings present demographic characteristics and social environment attributes as key factors that shape perceived neighborhood walkability. Findings can help inform programmatic efforts and environmental change strategies to improve walking in rural areas.

RESUMO

OBJECTIVES: A seminal study on loneliness and depression suggested that loneliness influences depression more than the reverse. However, the study's analytic method has since been criticized for failing to account for the trait-like nature of variables. This study aimed to examine the longitudinal relationship between loneliness and depressive symptoms while accounting for the trait-like nature of both variables. METHODS: Data (n = 16,478) came from the Health and Retirement Study (2006-2016). Measures included the Hughes Loneliness Scale and a modified Center for Epidemiologic Studies Depression scale (loneliness item omitted). Analyses consisted of random intercepts cross-lagged panel models (three time-points evenly spaced across eight years). RESULTS: There was evidence that loneliness and depressive symptoms are trait-like and these trait-like components are strongly associated. There was not evidence of cross-lagged effects between loneliness and depressive symptoms. CONCLUSIONS: A tendency toward loneliness corresponded with a tendency toward depressive symptoms. However, deviations in one's typical level of loneliness did not predict deviations in one's typical level of depressive symptoms or vice-versa. These findings do not support past assertions that loneliness shapes subsequent depression more than the reverse. CLINICAL IMPLICATIONS: By middle to late adulthood, loneliness and depressive symptoms are trait-like phenomena that are strongly associated.

RESUMO

Suicidality is a major public health concern, particularly for low-income, trauma-exposed patients with limited access to mental health providers. However, limited research has modeled pathways of suicidality in safety-net primary care samples. Patients (N = 207) in a safety-net primary care clinic completed measures of childhood and adult trauma exposure, depression, and suicidality. Participants (M age = 44.8 years, SD = 11.6), were 60.4% male, 63.8% Black/African American, and predominantly low-income (i.e., 69.1% reported an annual income less than $5,000 USD). Half of the sample reported at least four childhood traumatic events (M = 3.9 events, SD = 3.0) and approximately three adult traumatic events (M = 3.0 events, SD = 2.1). Most participants (82.1%) reported significant depressive symptoms, and 43.5% endorsed recent suicidality. Models showing the mediational effect of depression on the association between trauma exposure and suicidality, ß = .20, B = 0.23, SE = 0.05, 95% CI [0.16, 0.32], and the moderational effect of trauma exposure on the association between depression and suicidality, ß = .16, B = 0.20, SE = 0.08, p = .007, were both supported. These results underscore the high prevalence of trauma exposure, depression, and suicidality in a safety-net primary care sample. They also highlight the pervasiveness and complexity of suicidality in low-income primary care patients, emphasize the importance of trauma-informed suicide assessment, and identify trauma sequelae and depression as potential treatment targets to reduce suicidality.

RESUMO

BACKGROUND: As the research documenting loneliness as a risk factor for morbidity and mortality continues to grow, it becomes increasingly critical to understand the mechanics of this relationship. This study assessed whether sleep disturbance mediates the relationship between loneliness and health. METHOD: Data came from the 2006, 2010, and 2014 waves of the Health and Retirement Study, a longitudinal study of older Americans; participants ≥ 65 who completed the Psychosocial and Lifestyle Questionnaire in 2006 were included (n = 5067). Measures include the Hughes loneliness scales, a modified version of the Jenkins sleep scale, and self-reported health. Cross-lagged mediation models (i.e., path analysis) were used to model the relationships between loneliness, sleep disturbance, and self-reported health over the 8-year span. RESULTS: Loneliness predicted subsequent sleep disturbance, which in turn predicted subsequent self-reported health. Moreover, there was evidence of both direct and indirect effects (via sleep disturbance) of loneliness on self-reported health. These effects remained after controlling for demographics, isolation, and depression. CONCLUSION: Sleep disturbance partially mediates the relationship between loneliness and self-reported health over 8 years. These findings are not attributable to isolation or depression. Further research is necessary to develop and assess a more comprehensive model of how loneliness shapes health.

RESUMO

AIMS: The purpose of this study was to (1) characterise the procedure of phlebotomy, deconstruct it into its constituent parts and develop a performance metric for the purpose of training healthcare professionals in a large teaching hospital and to (2) evaluate the construct validity of the phlebotomy metric and establish a proficiency benchmark. METHOD: By engaging with a multidisciplinary team with a wide range of experience of preanalytical errors in phlebotomy and observing video recordings of the procedure performed in the actual working environment, we defined a performance metric. This was brought to a modified Delphi meeting, where consensus was reached by an expert panel. To demonstrate construct validity, we used the metric to objectively assess the performance of novices and expert practitioners. RESULTS: A phlebotomy metric consisting of 11 phases and 77 steps was developed. The mean inter-rater reliability was 0.91 (min 0.83, max 0.95). The expert group completed more steps of the procedure (72 vs 69), made fewer errors (19 vs 13, p=0.014) and fewer critical errors (1 Vs 4, p=0.002) than the novice group. CONCLUSIONS: The metrics demonstrated construct validity and the proficiency benchmark was established with a minimum observation of 69 steps, with no critical errors and no more than 13 errors in total.

RESUMO

BACKGROUND: Community pharmacies provide an appropriate setting to deliver minor ailment services (MASs). Many community pharmacy services have been developed previously without stakeholder involvement. As a result, implementation of services may fail to produce the expected impact. The aim of this research was to co-design and test the feasibility of an Australian MAS for minor ailment presentations. METHODS: This study used co-design methodology which included two phases: (1) a focus group with stakeholders to allow the conceptualization of the service and agreement on service elements; (2) a literature review of clinical guidelines and three working meetings with a team of editors and general practitioners for the development of treatment pathways. Following this, a study evaluating the feasibility of the co-designed service was undertaken. The qualitative part of the methodology associated with the feasibility study comprised semi-structured interviews with MAS pharmacists, observation and completion of a tool by change facilitators identifying barriers and facilitators to service delivery. Qualitative data obtained for all phases were analysed using thematic analysis. RESULTS: The developed service included the following components: (i) an in-pharmacy consultation between the patient and pharmacist, (ii) treatment pathways accessible to pharmacists on the internet to guide consultations, (iii) existing digital communication systems used by general practice to exchange patient information, (iv) training, and (v) change facilitation. As a result of feasibility testing, twenty-six implementation factors were identified for practice change, with the main change being the simplification of the pharmacist-patient consultation and data collection processes. CONCLUSIONS: An Australian MAS was generated as a result of co-design, while testing revealed that the co-designed service was feasible. As a result of integrating the views of multiple stakeholders, the designed MAS has been adapted to suit healthcare practices, which may increase the acceptance and impact of MAS when implemented into practice.
