RESUMO

Effective ocean management and the conservation of highly migratory species depend on resolving the overlap between animal movements and distributions, and fishing effort. However, this information is lacking at a global scale. Here we show, using a big-data approach that combines satellite-tracked movements of pelagic sharks and global fishing fleets, that 24% of the mean monthly space used by sharks falls under the footprint of pelagic longline fisheries. Space-use hotspots of commercially valuable sharks and of internationally protected species had the highest overlap with longlines (up to 76% and 64%, respectively), and were also associated with significant increases in fishing effort. We conclude that pelagic sharks have limited spatial refuge from current levels of fishing effort in marine areas beyond national jurisdictions (the high seas). Our results demonstrate an urgent need for conservation and management measures at high-seas hotspots of shark space use, and highlight the potential of simultaneous satellite surveillance of megafauna and fishers as a tool for near-real-time, dynamic management.

RESUMO

The complete genome sequence of cacao leafroll virus (CaLRV; family Solemoviridae, genus Polerovirus) was determined by high-throughput sequencing of total RNA isolated from symptomatic cacao Theobroma cacao L. plants (n = 4). The CaLRV genome sequences ranged from 5,976 to 5,997 nucleotides (nt) in length and contained seven open reading frames (ORFs). Nucleotide and amino acid (aa) sequence comparisons showed that, among selected well-characterized poleroviruses, the CaLRV genome shared the highest nt sequence identity of 62% with that of potato leafroll virus (PLRV, NC_076505). A comparison of the predicted aa sequence of the CaLRV coat protein indicated that cotton leafroll dwarf virus (CLRDV, NC_014545) and melon aphid-borne yellows virus (MABYV, NC_010809) were the closest relatives, sharing 57% aa sequence identity. Bayesian phylogenetic analysis based on complete genome sequences showed that CaLRV grouped with well-characterized poleroviruses that cause diseases of cereal and vegetable crops. During the course of publishing this work, the nearly complete genome sequence of a member of the same polerovirus species, referred to as "cacao polerovirus" (OR605721), with which CaLRV shares 99% nt sequence identity, was reported.

RESUMO

BACKGROUND: Family physicians (FPs) fill an essential role in public health emergencies yet have frequently been neglected in pandemic response plans. This exclusion harms FPs in their clinical roles and has unintended consequences in the management of concurrent personal responsibilities, many of which were amplified by the pandemic. The objective of our study was to explore the experiences of FPs during the first year of the COVID-19 pandemic to better understand how they managed their competing professional and personal priorities. METHODS: We conducted semi-structured interviews with FPs from four Canadian regions between October 2020 and June 2021. Employing a maximum variation sampling approach, we recruited participants until we achieved saturation. Interviews explored FPs' personal and professional roles and responsibilities during the pandemic, the facilitators and barriers that they encountered, and any gender-related experiences. Transcribed interviews were thematically analysed. RESULTS: We interviewed 68 FPs during the pandemic and identified four overarching themes in participants' discussion of their personal experiences: personal caregiving responsibilities, COVID-19 risk navigation to protect family members, personal health concerns, and available and desired personal supports for FPs to manage their competing responsibilities. While FPs expressed a variety of ways in which their personal experiences made their professional responsibilities more complicated, rarely did that affect the extent to which they participated in the pandemic response. CONCLUSIONS: For FPs to contribute fully to a pandemic response, they must be factored into pandemic plans. Failure to appreciate their unique role and circumstances often leaves FPs feeling unsupported in both their professional and personal lives. Comprehensive planning in anticipation of future pandemics must consider FPs' varied responsibilities, health concerns, and necessary precautions. Having adequate personal and practice supports in place will facilitate the essential role of FPs in responding to a pandemic crisis while continuing to support their patients' primary care needs.

RESUMO

Colonially breeding birds and mammals form some of the largest gatherings of apex predators in the natural world and have provided model systems for studying mechanisms of population regulation in animals. According to one influential hypothesis, intense competition for food among large numbers of spatially constrained foragers should result in a zone of prey depletion surrounding such colonies, ultimately limiting their size. However, while indirect and theoretical support for this phenomenon, known as "Ashmole's halo," has steadily accumulated, direct evidence remains exceptionally scarce. Using a combination of vessel-based surveys and Global Positioning System tracking, we show that pelagic seabirds breeding at the tropical island that first inspired Ashmole's hypothesis do indeed deplete their primary prey species (flying fish; Exocoetidae spp.) over a considerable area, with reduced prey density detectable >150 km from the colony. The observed prey gradient was mirrored by an opposing trend in seabird foraging effort, could not be explained by confounding environmental variability, and can be approximated using a mechanistic consumption-dispersion model, incorporating realistic rates of seabird predation and random prey dispersal. Our results provide a rare view of the resource footprint of a pelagic seabird colony and reveal how aggregations of these central-place foraging, marine top predators profoundly influence the oceans that surround them.

RESUMO

The aphid-transmitted polerovirus, cotton leafroll dwarf virus (CLRDV), first characterized from symptomatic cotton plants in South America, has been identified in commercial cotton plantings in the United States. Here, the CLRDV intraspecific diversity was investigated by comparative sequence analysis of the most divergent CLRDV coding region, ORF0/P0. Bayesian analysis of ORF0 sequences for U.S. and reference populations resolved three well-supported sister clades comprising one U.S. and two South American lineages. Principal component analysis (PCA) identified seven statistically supported intraspecific populations. The Bayesian phylogeny and PCA dendrogram-inferred relationships were congruent. Population analysis of ORF0 sequences indicated most lineages have evolved under negative selection, albeit certain sites/isolates evolved under positive selection. Both U.S. and South American isolates exhibited extensive ORF0 diversity. At least two U.S. invasion foci were associated with their founder populations in Alabama-Georgia and eastern Texas. The Alabama-Georgia founder is implicated as the source of recent widespread expansion and establishment of secondary disease foci throughout the southeastern-central United States. Based on the geographically restricted distribution, spread of another extant Texas population appeared impeded by a population bottleneck. Extant CLRDV isolates represent several putative introductions potentially associated with catastrophic weather events dispersing viruliferous cotton aphids of unknown origin(s).

RESUMO

Root crops, referred to as ground provisions in the Caribbean, are traditional staples in Trinidad. One widely consumed example is sweet potato (Ipomeas batatas L.). The crop is mainly produced by subsistence farming which together with imports from neighboring Caribbean countries meet domestic demand (Singh et al. 2008). The Central Experiment Station, situated in the eastern part of Trinidad, maintains a sweet potato germplasm collection comprising both imported and locally-sourced landraces for cultivar development and distribution of propagules. In May 2017 chlorosis and leaf curling symptoms, typically associated with sweepoviruses, were observed on imported cultivars, Centennial, Jewel, 86 BM 31, TIB 313, TIB 8 21 1, and S128, and the landraces, Kick Up Jenny, John, and Carrot. Leaf samples from these nine symptomatic plants were collected for analysis, along with samples from the asymptomatic landrace, Chickenfoot. Total nucleic acids were extracted (Sharma et al. 2008) and the samples were assayed by PCR using degenerate primers SPG1 and SPG2 (Li et al. 2004) that target the replication associated protein gene (ORF C1), a highly conserved region of sweepoviruses. Amplicons of 912-bp were obtained from two of the nine symptomatic plants (TIB 8 21 1, Kick Up Jenny), but not from the asymptomatic Chickenfoot. The same samples were assayed by PCR amplification using primers SpvF and SpvR (Avelar 2015) which are specific to a highly conserved 632-bp region of the coat protein gene (ORF V1) of sweet potato leaf curl virus (SPLCV). All 10 samples tested positive for SPLCV, including the asymptomatic landrace, Chickenfoot. The ORF V1 PCR products from three of the 10 samples, namely Chickenfoot, TIB 8 21 1, and Kick Up Jenny, were cloned and sequenced (two clones per sample). Comparison of the sequences (GenBank accession nos. OR882007 [Chickenfoot], OR913125 [TIB 8 21 1] and OR913126 [Kick Up Jenny]) identified up to 4% nt sequence variability between samples. In BLASTn analysis, they were most closely related to the SPLCV isolate China:Sichuan (GenBank accession no. KJ013557), sharing 94 to 98% nt identity. Total nucleic extracts from one representative sample (TIB 8 21 1) was used as template for rolling circle amplification (RCA, TempliPhi Amplification Kit, GE Healthcare Life Sciences, Piscataway, NJ, USA). Digestion of the RCA product with StuI (Thermo Scientific, MA, USA) yielded ~2.8 kb DNA fragments indicative of monomeric full length genomes. Digested fragments were cloned, completely sequenced and deposited in GenBank under the accession nos. OR866202 (2,821 nts) and OR866203 (2,828 nts). Two species of sweepoviruses were detected. In BLASTn analysis, OR866202 showed 95% nt identity with sweet potato golden vein associated virus (SPGVaV) US:MS:1B-3 (GenBank accession no. HQ333143.1) which is a recombinant virus comprised of SPLCV and sweet potato leaf curl Georgia virus (SPLCGV) (Zhang and Ling 2011) and in BLASTx analysis OR866202 was most similar (92-99%) to SPLCV isolates from Brazil (GenBank accession nos. ACI23475.1, AGW16179.1, ACY79479.1), Peru (GenBank accession no. ACY79466.1) and China (GenBank accession nos. ACY79439.1). OR866203 shared 96% nt identity with SPLCV China:Henan25(8):2012 (GenBank accession no. KF040465.1) in BLASTn analysis and BLASTx analysis revealed ≥ 94% aa sequence identity with SPLCV from Brazil (GenBank accession nos. ACI23475.1, AGW16179.1, ADZ96559.1), Peru (GenBank accession no. ACY79479.1), China (GenBank accession no. ACY79466.1). and Spain (GenBank accession no. QWQ56365.1). Both Trinidad isolates also showed 90-96% nt identity with SPLCV from Korea (GenBank accession no.s KT992061.1, KT992064.1, unpublished). This is the first detection of sweepoviruses in Trinidad. SPGVaV has been reported in Brazil, the United States and Korea (Kil et al. 2014), while SPLCV has been described in other Caribbean islands, including Cuba, Jamaica, Puerto Rico, St. Vincent (Cuellar et al. 2015), and Barbados (Alleyne et al. 2019), as well as several countries in South America. Although Koch's postulates were not completed, our findings suggest that sweet potato crops in Trinidad harbor sweepoviruses, notwithstanding efforts to distribute pathogen-free materials and, in some instances, the apparent absence of visible symptoms on infected plants. Further studies on the management and impact of these viruses are necessary, including their prevalence in the sweet potato production regions of Trinidad.

RESUMO

NAPCRG celebrated 50 years of leadership and service at its 2022 meeting. A varied team of primary care investigators, clinicians, learners, patients, and community members reflected on the organization's past, present, and future. Started in 1972 by a small group of general practice researchers in the United States, Canada, and the United Kingdom, NAPCRG has evolved into an international, interprofessional, interdisciplinary, and intergenerational group devoted to improving health and health care through primary care research. NAPCRG provides a nurturing home to researchers and teams working in partnership with individuals, families, and communities. The organization builds upon enduring values to create partnerships, advance research methods, and nurture a community of contributors. NAPCRG has made foundational contributions, including identifying the need for primary care research to inform primary care practice, practice-based research networks, qualitative and mixed-methods research, community-based participatory research, patient safety, practice transformation, and partnerships with patients and communities. Landmark documents have helped define classification systems for primary care, responsible research with communities, the central role of primary care in health care systems, opportunities to revitalize generalist practice, and shared strategies to build the future of family medicine. The future of health and health care depends upon strengthening primary care and primary care research with stronger support, infrastructure, training, and workforce. New technologies offer opportunities to advance research, enhance care, and improve outcomes. Stronger partnerships can empower primary care research with patients and communities and increase commitments to diversity and quality care for all. NAPCRG offers a home for all partners in this work.

RESUMO

BACKGROUND: Prior to the pandemic, Canada lagged behind other Organisation for Economic Cooperation and Development countries in the uptake of virtual care. The onset of COVID-19, however, resulted in a near-universal shift to virtual primary care to minimise exposure risks. As jurisdictions enter a pandemic recovery phase, the balance between virtual and in-person visits is reverting, though it is unlikely to return to pre-pandemic levels. Our objective was to explore Canadian family physicians' perspectives on the rapid move to virtual care during the COVID-19 pandemic, to inform both future pandemic planning for primary care and the optimal integration of virtual care into the broader primary care context beyond the pandemic. METHODS: We conducted semi-structured interviews with 68 family physicians from four regions in Canada between October 2020 and June 2021. We used a purposeful, maximum variation sampling approach, continuing recruitment in each region until we reached saturation. Interviews with family physicians explored their roles and experiences during the pandemic, and the facilitators and barriers they encountered in continuing to support their patients through the pandemic. Interviews were audio-recorded, transcribed, and thematically analysed for recurrent themes. RESULTS: We identified three prominent themes throughout participants' reflections on implementing virtual care: implementation and evolution of virtual modalities during the pandemic; facilitators and barriers to implementing virtual care; and virtual care in the future. While some family physicians had prior experience conducting remote assessments, most had to implement and adapt to virtual care abruptly as provinces limited in-person visits to essential and urgent care. As the pandemic progressed, initial forays into video-based consultations were frequently replaced by phone-based visits, while physicians also rebalanced the ratio of virtual to in-person visits. Medical record systems with integrated capacity for virtual visits, billing codes, supportive clinic teams, and longitudinal relationships with patients were facilitators in this rapid transition for family physicians, while the absence of these factors often posed barriers. CONCLUSION: Despite varied experiences and preferences related to virtual primary care, physicians felt that virtual visits should continue to be available beyond the pandemic but require clearer regulation and guidelines for its appropriate future use.

RESUMO

Citrus greening disease was first reported in Saudi Arabia during the 1970's when characteristic foliar and fruit symptoms were observed in commercial citrus groves, however, "Candidatus Liberibacter asiaticus" (CLas) was not detected in symptomatic trees until 1981-1984 when CLas-like cells were observed by transmission electron microscopy in leaves collected from symptomatic citrus groves in southwestern Saudi Arabia. Despite the anticipated establishment of the CLas-Asian citrus psyllid (ACP) (Diaphorina citri Kuwayama) pathosystem, CLas presence has not been verified in suspect trees nor have ACP infestations been documented. Given the recent expansion of citrus production in Saudi Arabia, a systematic country-wide survey was carried out to determine the potential CLas distribution in the thirteen citrus-growing regions of the country. Citrus trees were surveyed for presence of CLas-psyllid vector(s) and characteristic disease symptoms in commercial and urban citrus trees. Adult psyllids collected from infested citrus trees were identified as ACP based on morphological characteristics. Real-time, quantitative PCR amplification (qPCR) of the CLas ß-subunit of the ribonucleotide reductase (RNR) gene from citrus leaf and fruit samples and/or ACP adults, revealed trees were positive for CLas detection in ten of the 13 survey regions, however, CLas was undetectable in ACP adults. Phylogenetic and SNPs analyses of a PCR-amplified, cloned fragment of the CLas 16S rRNA gene (~1.1 kbp) indicated Saudi Arabian isolates were most closely related to Florida, USA isolates. Analysis of climate variables indicated that the distribution of the ACP-CLas pathosystem observed in Saudi Arabia was consistent with published predictions of terrains most likely to support establishment.

RESUMO

The development of interprofessional teams in primary care presents opportunities for social workers to take on new leadership positions. This study seeks to describe how social workers engaged in leadership roles in primary care during the COVID-19 pandemic. A cross-sectional on-line survey was disseminated to primary care social workers across Ontario, Canada, with a total of 159 respondents. Most respondents engaged in informal leadership roles and showcased a range of leadership skills promoting team collaboration and consultations, along with adapting to virtual care transitions. Findings suggest there needs to be intentional cultivation of social work leaders through supportive environments and training. Social workers in primary care have leadership capacity and are providing leadership to their primary care teams through formal and informal means. The leadership potential of social workers in primary care teams, however, is being underutilized and can be further developed.

RESUMO

Policy supports are needed to ensure that Family Physicians (FPs) can carry out pandemic-related roles. We conducted a document analysis in four regions in Canada to identify regulation, expenditure, and public ownership policies during the COVID-19 pandemic to support FP pandemic roles. Policies supported FP roles in five areas: FP leadership, Infection Prevention and Control (IPAC), provision of primary care services, COVID-19 vaccination, and redeployment. Public ownership polices were used to operate assessment, testing and vaccination, and influenza-like illness clinics and facilitate access to personal protective equipment. Expenditure policies were used to remunerate FPs for virtual care and carrying out COVID-19-related tasks. Regulatory policies were region-specific and used to enact and facilitate virtual care, build surge capacity, and enforce IPAC requirements. By matching FP roles to policy supports, the findings highlight different policy approaches for FPs in carrying out pandemic roles and will help to inform future pandemic preparedness.

RESUMO

Family physicians play important roles throughout all stages of a pandemic response; however, actionable descriptions outlining these roles are absent from current pandemic plans. Using a multiple case study design, we conducted a document analysis and interviewed 68 family physicians in four Canadian regions. We identified roles performed by family physicians in five distinct stages of pandemic response: pre-pandemic, phased closure and re-opening, acute care crisis, vaccination, and pandemic recovery. In addition to adopting public health guidance to ensure continued access to primary care services, family physicians were often expected to operationalize public health roles (eg, staffing assessment centres), modulate access to secondary/tertiary services, help provide surge capacity in acute care facilities, and enhance supports and outreach to vulnerable populations. Future pandemic plans should include family physicians in planning, explicitly incorporate family physician roles, and ensure needed resources are available to allow for an effective primary care response.

RESUMO

Context: On March 14, 2020, the Ontario, Canada health insurance plan approved COVID-19 physician virtual billing codes; family physicians (FPs) rapidly adopted a new model of care. Virtual care may remain post-pandemic; however, its future should be informed by evidence that considers access and continuity. Objective: 1) to determine FP virtual visit volumes and patient characteristics and 2) to explore FPs' perspectives on virtual visit adoption and implementation. Study Design: Mixed methods: Secondary analysis of health administrative (HA) data and semi-structured qualitative interviews with FPs. Setting or Dataset: London and Middlesex County, Ontario, Canada. HA data through ICES, Ontario entity holding data. Population studied: FPs and their patients. Outcome Measures: Volumes of FP in-person and virtual visits during early pandemic; characteristics of patients receiving care; FPs' perspectives on adopting and delivering virtual care. Results: Overall visit volume dropped by 36% during first wave, recovered to pre-pandemic levels by October 2020. Sharp in-person visit drop of 73% and virtual visit uptake from 0.08% of total visits to 57% within two weeks of March 2020. FPs described this initial drop in volume as patients not seeking care and practices lacking PPE. The move to virtual care was largely to telephone visits. Patient characteristics compared to pre-pandemic, the proportion seeking care were older (46 vs 50 years), more vulnerable (38% vs 41%), and more multimorbidity (33% vs 41%). This was consistent with FP reports that healthier patients stayed away, routine care deferred, sicker patients needed to be seen. FPs believed most vulnerable patients had access to care but cautioned highly vulnerable such as those homeless did not have cell phone access or a safe place to receive calls. Rural FPs reported access issues because of lack of high-speed internet. FPs attributed success of virtual care to the continuity in relationships they had with patients that were established in person pre-pandemic. Conclusions: FPs moved rapidly to virtual care. FP offices remained open despite PPE concerns but overall volumes dropped initially. Vulnerable and sicker patients received care but FPs expressed concern for highly vulnerable and rural residents. FPs believed they could offer patient-centred care over the phone but indicated the importance of maintaining in-person care to build relationships.

RESUMO

Context: The onset of COVID-19 has required the rapid adoption of virtual services in primary care (PC) practices, and virtual care delivery is likely to continue to some extent post-pandemic. Objective: To understand patient experience with synchronous virtual (telephone (Tel)/Video) appointments and elicit recommendations for its future use. Design: Mixed method, including patient survey co-developed with stakeholders and implemented online Feb-Mar 2021 with large promotional efforts through social media, patient and caregiver organizations, and other networks. We report on the survey results. Eligibility: 1+ virtual encounter in PC. Outcome measures: A) Patient experience scale (12/17 questions for Tel/Video) covering 4 sub-dimensions; B) Access related questions. Questions had 5-point Likert scale items (strongly disagree (-2) to strongly agree (+2)) and were converted into percentage (potential range -100%, +100%) Setting : Ontario, Canada which offers universal coverage for PC visits with no co-payment. Results: 534 eligible respondents (402/18/114 had Tel/Video/both): Females (78%), < 55 years (61%), white (75%), employed (61%), bachelor's degree (74%), family income > 100k (52%). Encounters evaluated were with family physicians (vs other health professionals) for 75%/46% of Tel/Video encounters. A) Patient Experience (Tel/Video) overall score: 75%/78%; Sub-dimensions: technology: 92%/84%, patient-provider relationship: 83%/86%, quality of care: 66%/66%, whole-person care: 43%/53%. Factors associated with a statistically significant(*) > 10% higher overall score in tel and/or video were: non-females: (8%*/14%*), French speaking (13%*/16%*), patient-provider relationship >1 year (16%*/7%), provider age < 50 (5%/15%*), having the choice of appointment time (15%*/21%*). Wanting to show problem to the provider was associated with a lower scores (-23%*/NA). B) Access Respondents overwhelmingly reported that Tel/Video visits reduced time (97%/97%), costs (81%/85%), and was more convenient (91%/91%). The majority wanted Tel (69%) and Video (71%) visits at least as often as in person visits post-covid. Only 5% did not want any future virtual care. Conclusions: Patient experience was largely positive and is influenced by patient/provider factors. Patients and providers may benefit from support/training to optimize care experience. We are now evaluating whether the reasons for visits influences care experience.

RESUMO

Context: The effective deployment of artificial intelligence (AI) in primary health care requires a match between the AI tools that are being developed and the needs of primary health care practitioners and patients. Currently, the majority of AI development targeted toward potential application in primary care is being conducted without the involvement of these stakeholders. Objective: To identify key issues regarding the use of AI tools in primary health care by exploring the views of primary health care and digital health stakeholders. Study Design: A descriptive qualitative approach was taken in this study. Fourteen in-depth interviews were conducted with primary care and digital health stakeholders. Setting: Province of Ontario, Canada Population studied: Primary health care and digital health stakeholders Outcome Measures: N/A Results: Two main themes emerged from the data analysis: Worth the Risk as Long as You Do It Well; and, Mismatch Between Envisioned Uses and Current Reality. Participants noted that AI could have value if used for specific purposes, for example: supporting care for patients; reducing practitioner burden; analyzing existing evidence; managing patient populations; and, supporting operational efficiencies. Participants identified facilitators of AI being used for these purposes including: use of relevant case studies/success stories with realistic uses of AI highlighted; easy or low risk applications; and, end user involvement. However, barriers to the use of AI included: data quality; digital divide/equity; distrust of AI including security/privacy issues; for-profit motives; need for transparency about how AI works; and, fear about impact on practitioners regarding clinical judgement. Conclusion: AI will continue to become more prominent in primary health care. There is potential for positive impact, however there are many factors that need to be considered regarding the implementation of AI. The findings of this study can help to inform the development and deployment of AI tools in primary health care.

RESUMO

CONTEXT: Artificial intelligence (AI) is increasingly being recognized as having potential importance to primary care (PC). However, there is a gap in our understanding about where to focus efforts related to AI for PC settings, especially given the current COVID-19 pandemic. OBJECTIVE: To identify current priority areas for AI and PC in Ontario, Canada. STUDY DESIGN: Multi-stakeholder engagement event with facilitated small and large group discussions. A nominal group technique process was used to identify and rank challenges in PC that AI may be able to support. Mentimeter software was used to allow real-time, anonymous and independent ranking from all participants. A final list of priority areas for AI and PC, with key considerations, was derived based on ranked items and small group discussion notes. SETTING: Ontario, Canada. POPULATION STUDIED: Digital health and PC stakeholders. OUTCOME MEASURES: N/A. RESULTS: The event included 8 providers, 8 patient advisors, 4 decision makers, 3 digital health stakeholders, and 12 researchers. Nine priority areas for AI and PC were identified and ranked, which can be grouped into those intended to support physician (preventative care and risk profiling, clinical decision support, routine task support), patient (self-management of conditions, increased mental health care capacity and support), or system-level initiatives (administrative staff support, management and synthesis of information sources); and foundational areas that would support work on other priorities (improved communication between PC and AI stakeholders, data sharing and interoperability between providers). Small group discussions identified barriers and facilitators related to the priorities, including data availability, quality, and consent; legal and device certification issues; trust between people and technology; equity and the digital divide; patient centredness and user-centred design; and the need for funding to support collaborative research and pilot testing. Although identified areas do not explicitly mention COVID-19, participants were encouraged to think about what would be feasible and meaningful to accomplish within a few years, including considerations of the COVID-19 pandemic and recovery phases. CONCLUSIONS: A one-day multi-stakeholder event identified priority areas for AI and PC in Ontario. These priorities can serve as guideposts to focus near-term efforts on the planning, development, and evaluation of AI for PC.

RESUMO

INTRODUCTION: Health system disruptions, caused by unexpected emergencies such as disease outbreaks, natural disasters, and cybercrimes, impact the delivery of routine preventative care. As comprehensive care providers, family physicians (FPs) devote significant time to prevention. However, without emergency and pandemic plans in place in primary care, FPs face added barriers to prioritizing and sustaining preventative care when health systems are strained, which was evident during the COVID-19 pandemic. This study aims to describe FPs' experiences providing preventative care during the COVID-19 pandemic and their perceptions of the impacts of disrupted preventative care in primary care settings. METHODS: Using a qualitative descriptive approach, we conducted semistructured interviews with FPs across 4 provinces in Canada (i.e. Newfoundland and Labrador, Nova Scotia, Ontario, British Columbia) between October 2020 and June 2021 as part of a larger multiple case study. These interviews broadly explored the roles and responsibilities of FPs during the COVID-19 pandemic. Interviews were coded thematically and codes from the larger study were analysed further using an iterative, phased process of thematic analysis. RESULTS: Interviews averaged 58 min in length (range 17-97 min) and FPs had a mean of 16.9 years of experience. We identified 4 major themes from interviews with FPs (n = 68): (i) lack of capacity and coordination across health systems, (ii) patient fear, (iii) impacts on patient care, and (iv) negative impacts on FPs. Physicians voiced concerns with managing patients' prevention needs when testing availability and coordination of services was limited. Early in the pandemic, patients were also missing or postponing their own primary care appointments. Change in the provision and coordination of routine preventative care had negative impacts on both patients and physicians, affecting disease incidence/progression, physician workload, and psychological wellbeing. CONCLUSION: During the COVID-19 pandemic, upstream care efforts were impacted, and FPs were forced to reduce their provision of preventative care. FPs contribute direct insight to primary care delivery that can support pandemic planning to ensure preventative care is sustained during future emergencies.

RESUMO

BACKGROUND: Effective deployment of AI tools in primary health care requires the engagement of practitioners in the development and testing of these tools, and a match between the resulting AI tools and clinical/system needs in primary health care. To set the stage for these developments, we must gain a more in-depth understanding of the views of practitioners and decision-makers about the use of AI in primary health care. The objective of this study was to identify key issues regarding the use of AI tools in primary health care by exploring the views of primary health care and digital health stakeholders. METHODS: This study utilized a descriptive qualitative approach, including thematic data analysis. Fourteen in-depth interviews were conducted with primary health care and digital health stakeholders in Ontario. NVivo software was utilized in the coding of the interviews. RESULTS: Five main interconnected themes emerged: (1) Mismatch Between Envisioned Uses and Current Reality-denoting the importance of potential applications of AI in primary health care practice, with a recognition of the current reality characterized by a lack of available tools; (2) Mechanics of AI Don't Matter: Just Another Tool in the Toolbox- reflecting an interest in what value AI tools could bring to practice, rather than concern with the mechanics of the AI tools themselves; (3) AI in Practice: A Double-Edged Sword-the possible benefits of AI use in primary health care contrasted with fundamental concern about the possible threats posed by AI in terms of clinical skills and capacity, mistakes, and loss of control; (4) The Non-Starters: A Guarded Stance Regarding AI Adoption in Primary Health Care-broader concerns centred on the ethical, legal, and social implications of AI use in primary health care; and (5) Necessary Elements: Facilitators of AI in Primary Health Care-elements required to support the uptake of AI tools, including co-creation, availability and use of high quality data, and the need for evaluation. CONCLUSION: The use of AI in primary health care may have a positive impact, but many factors need to be considered regarding its implementation. This study may help to inform the development and deployment of AI tools in primary health care.
