RESUMO

This practice guideline provides updated evidence-based conclusions and recommendations regarding the effects of antiseizure medications (ASMs) and folic acid supplementation on the prevalence of major congenital malformations (MCMs), adverse perinatal outcomes, and neurodevelopmental outcomes in children born to people with epilepsy of childbearing potential (PWECP). A multidisciplinary panel conducted a systematic review and developed practice recommendations following the process outlined in the 2017 edition of the American Academy of Neurology Clinical Practice Guideline Process Manual. The systematic review includes studies through August 2022. Recommendations are supported by structured rationales that integrate evidence from the systematic review, related evidence, principles of care, and inferences from evidence. The following are some of the major recommendations. When treating PWECP, clinicians should recommend ASMs and doses that optimize both seizure control and fetal outcomes should pregnancy occur, at the earliest possible opportunity preconceptionally. Clinicians must minimize the occurrence of convulsive seizures in PWECP during pregnancy to minimize potential risks to the birth parent and to the fetus. Once a PWECP is already pregnant, clinicians should exercise caution in attempting to remove or replace an ASM that is effective in controlling generalized tonic-clonic or focal-to-bilateral tonic-clonic seizures. Clinicians must consider using lamotrigine, levetiracetam, or oxcarbazepine in PWECP when appropriate based on the patient's epilepsy syndrome, likelihood of achieving seizure control, and comorbidities, to minimize the risk of MCMs. Clinicians must avoid the use of valproic acid in PWECP to minimize the risk of MCMs or neural tube defects (NTDs), if clinically feasible. Clinicians should avoid the use of valproic acid or topiramate in PWECP to minimize the risk of offspring being born small for gestational age, if clinically feasible. To reduce the risk of poor neurodevelopmental outcomes, including autism spectrum disorder and lower IQ, in children born to PWECP, clinicians must avoid the use of valproic acid in PWECP, if clinically feasible. Clinicians should prescribe at least 0.4 mg of folic acid supplementation daily preconceptionally and during pregnancy to any PWECP treated with an ASM to decrease the risk of NTDs and possibly improve neurodevelopmental outcomes in the offspring.

RESUMO

BACKGROUND: Extended pleurectomy decortication for complete macroscopic resection for pleural mesothelioma has never been evaluated in a randomised trial. The aim of this study was to compare outcomes after extended pleurectomy decortication plus chemotherapy versus chemotherapy alone. METHODS: MARS 2 was a phase 3, national, multicentre, open-label, parallel two-group, pragmatic, superiority randomised controlled trial conducted in the UK. The trial took place across 26 hospitals (21 recruiting only, one surgical only, and four recruiting and surgical). Following two cycles of chemotherapy, eligible participants with pleural mesothelioma were randomly assigned (1:1) to surgery and chemotherapy or chemotherapy alone using a secure web-based system. Individuals aged 16 years or older with resectable pleural mesothelioma and adequate organ and lung function were eligible for inclusion. Participants in the chemotherapy only group received two to four further cycles of chemotherapy, and participants in the surgery and chemotherapy group received pleurectomy decortication or extended pleurectomy decortication, followed by two to four further cycles of chemotherapy. It was not possible to mask allocation because the intervention was a major surgical procedure. The primary outcome was overall survival, defined as time from randomisation to death from any cause. Analyses were done on the intention-to-treat population for all outcomes, unless specified. This study is registered with ClinicalTrials.gov, NCT02040272, and is closed to new participants. FINDINGS: Between June 19, 2015, and Jan 21, 2021, of 1030 assessed for eligibility, 335 participants were randomly assigned (169 to surgery and chemotherapy, and 166 to chemotherapy alone). 291 (87%) participants were men and 44 (13%) women, and 288 (86%) were diagnosed with epithelioid mesothelioma. At a median follow-up of 22·4 months (IQR 11·3-30·8), median survival was shorter in the surgery and chemotherapy group (19·3 months [IQR 10·0-33·7]) than in the chemotherapy alone group (24·8 months [IQR 12·6-37·4]), and the difference in restricted mean survival time at 2 years was -1·9 months (95% CI -3·4 to -0·3, p=0·019). There were 318 serious adverse events (grade ≥3) in the surgery group and 169 in the chemotherapy group (incidence rate ratio 3·6 [95% CI 2·3 to 5·5], p<0·0001), with increased incidence of cardiac (30 vs 12; 3·01 [1·13 to 8·02]) and respiratory (84 vs 34; 2·62 [1·58 to 4·33]) disorders, infection (124 vs 53; 2·13 [1·36 to 3·33]), and additional surgical or medical procedures (15 vs eight; 2·41 [1·04 to 5·57]) in the surgery group. INTERPRETATION: Extended pleurectomy decortication was associated with worse survival to 2 years, and more serious adverse events for individuals with resectable pleural mesothelioma, compared with chemotherapy alone.

RESUMO

School closures in March 2020 due to the COVID-19 pandemic precipitated losses of critical student resources as physical, mental, emotional, and social needs escalated. Identifying the challenges, strategies, and changes in school nurse (SN) practice in Massachusetts during this pandemic is fundamental to understanding how to manage future anticipated pandemics while protecting children, communities, and SNs. The purpose of this mixed-methods descriptive study in the second year of the global pandemic was to (a) listen to SN voices through a novel online survey including the prompts of challenges, strategies, and practice changes and (b) describe the SN experience of COVID-19 response in Massachusetts schools, including identification of intent to leave school nursing. Responses were analyzed using descriptive qualitative analysis (n = 73). The prompts each elicited subthemes that coalesced to a cohesive theme: Finding one's way required the support of others to pave untraversed roads.

RESUMO

BACKGROUND: The BETTER intervention is an effective comprehensive evidence-based program for chronic disease prevention and screening (CDPS) delivered by trained prevention practitioners (PPs), a new role in primary care. An adapted program, BETTER HEALTH, delivered by public health nurses as PPs for community residents in low income neighbourhoods, was recently shown to be effective in improving CDPS actions. To obtain a nuanced understanding about the CDPS needs of community residents and how the BETTER HEALTH intervention was perceived by residents, we studied how the intervention was adapted to a public health setting then conducted a post-visit qualitative evaluation by community residents through focus groups and interviews. METHODS: We first used the ADAPT-ITT model to adapt BETTER for a public health setting in Ontario, Canada. For the post-PP visit qualitative evaluation, we asked community residents who had received a PP visit, about steps they had taken to improve their physical and mental health and the BETTER HEALTH intervention. For both phases, we conducted focus groups and interviews; transcripts were analyzed using the constant comparative method. RESULTS: Thirty-eight community residents participated in either adaptation (n = 14, 64% female; average age 54 y) or evaluation (n = 24, 83% female; average age 60 y) phases. In both adaptation and evaluation, residents described significant challenges including poverty, social isolation, and daily stress, making chronic disease prevention a lower priority. Adaptation results indicated that residents valued learning about CDPS and would attend a confidential visit with a public health nurse who was viewed as trustworthy. Despite challenges, many recipients of BETTER HEALTH perceived they had achieved at least one personal CDPS goal post PP visit. Residents described key relational aspects of the visit including feeling valued, listened to and being understood by the PP. The PPs also provided practical suggestions to overcome barriers to meeting prevention goals. CONCLUSIONS: Residents living in low income neighbourhoods faced daily stress that reduced their capacity to make preventive lifestyle changes. Key adapted features of BETTER HEALTH such as public health nurses as PPs were highly supported by residents. The intervention was perceived valuable for the community by providing access to disease prevention. TRIAL REGISTRATION: #NCT03052959, 10/02/2017.

RESUMO

AIM: There is limited research on the effects of sociodemographic and socioeconomic factors on treatment outcomes in youth at clinical high risk for psychosis (CHRp). This study examined sociodemographic factors that may affect functional outcomes within this population. Specifically, we investigated the influence of race/ethnicity (dichotomized as non-Hispanic whites [NHW] vs. people of colour [POC]), socioeconomic status (SES; operationalized as parental years of education), and their interaction on change in psychosocial functioning and symptoms over 6 months in a randomized trial of family-focused therapy. METHODS: CHRp youth (N = 128) participated in a randomized trial of family therapy (18 sessions of family therapy vs. 3 sessions of family psychoeducation). Sixty-four participants who self-identified as POC and 64 self-identified NHW participants completed baseline and 6-month follow-up measures of positive and negative symptoms and psychosocial (global, role, and social) functioning. Multiple regression models were conducted to test the main effect of race/ethnicity on changes in positive and negative symptoms and functioning, and whether this effect was moderated by parental education. RESULTS: There was a significant interaction between race/ethnicity and parental education, such that higher parental education was associated with greater improvement in global functioning in NHW participants, but there was no relationship between parental education and global functioning in POC. Additionally, higher parental education was associated with a decrease in negative symptoms in NHW participants but not in POC. There were no significant effects of race/ethnicity or parental education on positive symptoms, nor on social or role functioning. CONCLUSIONS: Clinicians may consider tailoring psychosocial treatments according to the needs of diverse families who vary in sociodemographic factors such as educational attainment and race/ethnicity.

RESUMO

PURPOSE: CONVERT was a phase 3 international randomized clinical trial comparing once-daily (OD) and twice-daily (BD) radiation therapy (RT). This updated analysis describes the 6.5-year outcomes of these regimens delivered with conformal techniques. METHODS AND MATERIALS: CONVERT (NCT00433563) randomized patients 1:1 between OD RT (66 Gy/33 fractions/6.5 weeks) and BD RT (45 Gy/30 fractions/3 weeks), both delivered with concurrent cisplatin/etoposide. Three-dimensional conformal RT was mandatory, intensity-modulated RT was permitted, and elective nodal irradiation was not allowed. Prophylactic cranial irradiation was delivered at the discretion of treating clinicians. RT treatment planning was subject to central quality assurance. RESULTS: Five hundred forty-seven patients were recruited at 73 centers. The median follow-up for the surviving cohort (n = 164) was 81.2 months. The median survival for the OD and BD arms were 25.4 months (95% CI, 21.1-30.9) and 30.0 months (95% CI, 25.3-36.5; hazard ratio, 1.13; 95% CI, 0.92-1.38; P = .247). Performance status and tumor volume were associated with survival on multivariate analysis. No treatment-related deaths occurred subsequent to the initial analysis performed in 2017. Regarding late toxicity, 7 patients in the OD arm developed grade 3 esophagitis, 4 of which went on to develop stricture or fistulation, compared with no patients in the BD arm. Grade 3 pulmonary fibrosis occurred in 2 and 3 patients in the OD and BD arms, respectively. CONCLUSIONS: As the CONVERT trial did not demonstrate the superiority of OD RT and this regimen had a slightly worse toxicity profile after 80 months of follow-up, 45 Gy BD should remain the standard of care in limited stage small cell lung cancer.

RESUMO

BACKGROUND: A twelve-gene molecular expression assay (DCIS score) may help guide radiation oncology treatment under specific circumstances. We undertook a study to examine radiation oncologist (RO), surgeon, and decision maker views on implementing the DCIS score in practice for women with low-risk DCIS. METHODS: We conducted a qualitative study involving telephone interviews that were audio-recorded and transcribed. Two researchers conducted a thematic analysis of transcripts. RESULTS: Twenty-eight individuals (ROs, breast cancer surgeons, and cancer policy decision makers) were invited to participate; 22 out of the 28 people (79%) agreed. The final sample included 20 participants: 11 of 13 (85%) ROs, 5 of 7 (71%) surgeons, and 4 of 8 (50%) decision makers. Most ROs expressed concerns about overtreatment but could not predict with certainty which low-risk patients could safely avoid radiation. The DCIS score was viewed as contributing valuable personalized risk information as part of treatment decision making that included clinicopathological factors and women's preferences. Future implementation would require guidelines with input from the oncology team. CONCLUSIONS: ROs had concerns about the overtreatment of women with DCIS, but lacked the tools to reliably predict which women could safely avoid radiation. By providing oncologists and women with personalized tumor information, the DCIS score was an important component of treatment decision making.

RESUMO

BACKGROUND: Clinical and preclinical research indicates that gastric weight loss surgeries, such as Roux-en-Y gastric bypass surgery, can induce alcohol use disorder (AUD). While numerous mechanisms have been proposed for these effects, one relatively unexplored potential mechanism is physical damage to the gastric branch of the vagus nerve, which can occur during bypass surgery. Therefore, we hypothesized that direct damage to the gastric branch of the vagus nerve, without altering other aspects of gastric anatomy, could result in increased alcohol intake. METHODS: To test this hypothesis, we compared alcohol intake and preference in multiple models in male Sprague-Dawley rats that received selective gastric branch vagotomy (VX) with rats who underwent sham surgery. Because the vagus nerve regulates hypothalamic-pituitary-adrenal (HPA) axis function, and alterations to HPA function are critical to the escalation of non-dependent alcohol intake, we also tested the hypothesis that gastric VX increases HPA function. RESULTS: We found that VX increases alcohol intake and preference in the every-other-day, two-bottle choice test and increases preference for 1 g/kg alcohol in the conditioned place preference test. The effects were selective for alcohol, as sucrose intake and preference were not altered by VX. We also found that VX increases corticotropin releasing factor (CRF) mRNA in the paraventricular nucleus of the hypothalamus (PVN), increases putative PVN CRF neuronal action potential firing, and increases corticosterone levels. CONCLUSIONS: Overall, these findings suggest that the vagus nerve may play a critical role in regulating HPA axis function via modulation of PVN CRF mRNA expression and putative PVN CRF neuronal activity. Furthermore, disruptions to vagal regulation of HPA axis function may increase alcohol intake and preference.

RESUMO

Background: Family caregivers of people with motor neurone disease (MND) experience adverse health outcomes as a result of their caregiving experience. This may be alleviated if their support needs are identified and addressed in a systematic and timely manner. The objective of this pilot study was to assess the feasibility and relevance of the Carers' Alert Thermometer (CAT) in home-based care, from the perspective of MND family caregivers. The tool provides a formal structure to facilitate discussions with caregivers to enable needs to be addressed. Methods: This mixed-method study was conducted in Western Australia (2020-2021). Forty-one caregivers and five MND Advisors participated in trialling the CAT intervention which consisted of two encounters with Advisors (6-8 weeks apart) to identify and address support needs through action plans. Caregivers' feedback was obtained via telephone interviews and a thematic analysis was undertaken. Results: Thirty caregivers completed two CAT assessments. Caregivers identified support priorities of managing their feelings and worries, providing emotional or spiritual care, information about the person's condition and how their care needs might change. Seventeen caregivers were interviewed and found that this assessment process adequately addressed their needs and it should be continued, it brought the focus onto them to clarify problems and work through solutions. The improvements that were suggested by them, including better information/education in palliative care, led to the development of an online support/information toolkit, which served to empower caregivers and staff by accessing relevant information and resources. Conclusions: The CAT demonstrated utility for triaging caregivers most in need of additional support and those whom signposting to additional information and self-directed access to support was most appropriate. For any tool to become an integrated part of care, service provider support is key for implementation, allowing for the time resource required and an appropriate education and support structure. MND Associations have an important role in building stronger partnerships with supportive community networks, through compassionate communities models of care, to address the identified needs of MND families in a more sustainable and wholistic manner. Needs assessment is a means towards building this capacity between formal and informal networks.

RESUMO

BACKGROUND: Primary care is integral to the health system and population health. Primary care research is still in development and most academic departments lack effective research investments. High impact primary care research programs are needed to advance the field to ensure a robust primary care system for the future. The project objective was to understand key informants' views of structures, functions, and processes required to create a high impact research program in an academic primary care department. METHODS: A descriptive qualitative project with key informants from research programs in primary care. Participants included international research leaders in primary care (n = 10), department of family and community researchers (n = 37) and staff (n = 9) in an academic primary care department, other university leaders (n = 3) and members of the departmental executive leadership team (1 department; 25 members). Semi-structured interviews (n = 27), and focus groups (n = 6) were audio recorded, transcribed, and analyzed using thematic analysis. We used a socioecological framework which described micro, meso, macro levels of influence. RESULTS: At the micro level despite barriers with respect to funding, protected time and lack of formal mentorship, personal motivation was a key factor. At the meso level, the organizational structure that promoted collaboration and a sense of connection emerged as a key factor. Specifically research leaders identified a research faculty development pipeline based on equity, diversity, inclusion, indigeneity, and accessibility principles with thematic areas of focus as key enablers. Lastly, at the macro level, an overarching culture and policies that promoted funding and primary care research was associated with high impact programs. CONCLUSION: The alignment/complementarity of micro, meso, and macro level factors influenced the creation of a high impact research department in primary care. High impact research in primary care is facilitated by the development of researchers through formalized and structured mentorship/sponsorship and a department culture that promote primary care research.

RESUMO

PURPOSE: To examine the effectiveness of professionally led support groups for people with advanced or metastatic cancer, and identify factors critical to implementation success within real-world settings. METHODS: Databases (MEDLINE; PsychINFO; CINAHL) and grey literature were searched for empirical publications and evaluations. Articles were screened for eligibility and data systematically extracted, charted and summarised using a modified scoping review methodology. Implementation factors were mapped using Proctor's implementation framework and the Consolidated Framework for Implementation Research 2.0. RESULTS: A total of 1691 publications were identified; 19 were eligible for inclusion (8 randomised controlled trials, 7 qualitative studies, 2 cohort studies, 2 mixed methods studies). Most (n=18) studies focused on tumour-specific support groups. Evidence supported professionally led support groups in reducing mood disturbances (n=5), distress (i.e. traumatic stress, depression) (n=4) and pain (n=2). Other benefits included social connectedness (n=6), addressing existential distress (n=5), information and knowledge (n=6), empowerment and sense of control (n=2), relationships with families (n=2) and communication with health professionals (n=2). Thirteen studies identified factors predicting successful adoption, implementation or sustainment, including acceptability (n=12; 63%), feasibility (n=6; 32%) and appropriateness (n=1; 5%). Key determinants of successful implementation included group leaders' skills/experience, mode of operation, travelling distance, group composition and membership and resourcing. CONCLUSIONS: Professionally led tumour-specific support groups demonstrate effectiveness in reducing mood disturbances, distress and pain among patients. Successful implementation hinges on factors such as leadership expertise, operational methods and resource allocation. IMPLICATIONS FOR CANCER SURVIVORS: Professionally led support groups may fill an important gap in supportive care for people with advanced or metastatic cancer.

RESUMO

PURPOSE: Cardiotoxicity is a common and under-reported side effect of tyrosine-kinase inhibitors (TKI) and immune checkpoint inhibitors (ICI). Baseline risk factors may help in risk-stratifying patients at increased risk of cardiotoxicity. This real-world study investigated the effects of baseline risk factors in cardiotoxicity on patients with non-small-cell lung cancer (NSCLC) treated with TKIs and ICIs. METHODS: This is a retrospective study carried out at The Royal Marsden Hospital, UK. Newly diagnosed patients with localized or metastatic NSCLC who received anticancer therapy with TKIs and/or ICIs were eligible. Patients who received only chemotherapy were excluded. Patients were followed up from the time of diagnosis until death or discharge. The relationship between cardiotoxicity and risk factors were tested by logistic regression. RESULTS: Of 88/451 (19.5%) patients developed cardiotoxicity. Risk factors hypothesized to have a causal relationship with anticancer treatment-induced cardiotoxicity were analyzed. Cardiotoxicity risk was increased with prior diabetes mellitus (OR = 1.93, 95% CI, 1.04-3.61, P = .038), history of smoking (OR = 1.91, 95% CI, 1.13-3.22, P = .016) and presence of baseline cardiovascular disease (OR = 2.03, 95% CI, 1.13-3.64, P = .018). The risk of developing cardiotoxicity increased in patients for smokers with diabetes mellitus (OR = 3.03, 95% CI, 1.40-6.55, P < .01) and for smokers with previous cardiovascular disease (OR = 1.99, 95% CI, 1.03-3.84, P = .041). CONCLUSION: Diabetes mellitus, smoking and baseline cardiovascular disease may synergistically contribute to cardiotoxicity when a patient is exposed to potentially cardiotoxic anticancer agents. Risk stratification at baseline may improve cardio-oncology care.

RESUMO

BACKGROUND: Few tissue biomarkers exist to date that could enrich patient with cancer populations to benefit from immune checkpoint blockade by programmed cell death protein 1/ligand-1 (PD-/L-1) inhibitors. PD-L1 expression has value in this context in some tumor types but is an imperfect predictor of clinical benefit. In malignant pleural mesothelioma, PD-L1 expression is not predictive of the benefit from PD-1 blockade. We aimed to identify novel markers in malignant pleural mesothelioma to select patients better. METHODS: We performed a multiplex-immune histochemistry analysis of tumor samples from the phase III PROMISE-meso study, which randomized 144 pretreated patients to receive either pembrolizumab or standard second-line chemotherapy. Our panel focused on CD8+T cell, CD68+macrophages, and the expression of PD-1 and PD-L1 on these and cancer cells. We analyzed single and double positive cells within cancer tissues (infiltrating immune cells) and in the stroma. In addition, we performed cell neighborhood analysis. The cell counts were compared with clinical outcomes, including responses, progression-free and overall survivals. RESULTS: We confirmed the absence of predictive value for PD-L1 in this cohort of patients. Furthermore, total CD8 T cells, CD68+macrophages, or inflammatory subtypes (desert, excluded, inflamed) did not predict outcomes. In contrast, PD-1-expressing CD8+T cells (exhausted T cells) and PD-1-expressing CD68+macrophages were both independent predictors of progression-free survival benefit from pembrolizumab. Patients with tumors simultaneously harboring PD1+T cells and PD-1+macrophages benefited the most from immune therapy. CONCLUSION: We analyzed a large cohort of patients within a phase III study and found that not only PD-1+CD8 T cells but also PD-1+CD68+ macrophages are predictive. This data provides evidence for the first time for the existence of PD-1+macrophages in mesothelioma and their clinical relevance for immune checkpoint blockade.

RESUMO

Assigning stress to the appropriate syllable is consequential for being understood. Despite the importance, second language (L2) learners' stress assignment is often incorrect, being affected by their first language (L1). Beyond the L1, learners' lexical stress assignment may depend on analogy with other words in their lexicon. The current study investigates the respective roles of the L1 (English, French) and analogy in L2 German lexical stress assignment. Because English, like German, has variable stress assignment and French does not, participants included English- and French-speaking German L2 learners who assigned stress to German nonsense words in a perceptual preference and a production task. Results suggest a role of the L1, with English-speaking German L2 learners performing more like L1 German speakers. While French-speaking German L2 learners' performance could not be predicted by other factors, L2 German proficiency and the ability to produce analogous words were predictive of English-speaking German L2 learners' production performance.

RESUMO

Increasing evidence suggests that some immunotherapy dosing regimens for patients with advanced cancer could result in overtreatment. Given the high costs of these agents, and important implications for quality of life and toxicity, new approaches are needed to identify and reduce unnecessary treatment. Conventional two-arm non-inferiority designs are inefficient in this context because they require large numbers of patients to explore a single alternative to the standard of care. Here, we discuss the potential problem of overtreatment with anti-PD-1 directed agents in general and introduce REFINE-Lung (NCT05085028), a UK multicentre phase 3 study of reduced frequency pembrolizumab in advanced non-small-cell lung cancer. REFINE-Lung uses a novel multi-arm multi-stage response over continuous interventions (MAMS-ROCI) design to determine the optimal dose frequency of pembrolizumab. Along with a similarly designed basket study of patients with renal cancer and melanoma, REFINE-Lung and the MAMS-ROCI design could contribute to practice-changing advances in patient care and form a template for future immunotherapy optimisation studies across cancer types and indications. This new trial design is applicable to many new or existing agents for which optimisation of dose, frequency, or duration of therapy is desirable.

RESUMO

BACKGROUND AND PURPOSE: Over the past decade, patient engagement (PE) has emerged as an important way to help improve the relevance, quality, and impact of health research. However, there is limited consensus on how best to meaningfully engage patients in the research process. The goal of this article is to share our experiences and insights as members of a Patient Advisory Committee (PAC) on a large, multidisciplinary cancer research study that has spanned six years. We hope by sharing our reflections of the PAC experiences, we can highlight successes, challenges, and lessons learned to help guide PE in future health research. To the best of our knowledge, few publications describing PE experiences in health research teams have been written by patients, survivors, or family caregivers themselves. METHODS: A qualitative approach was used to gather reflections from members of the Patient Advisory Committee regarding their experiences in participating in a research study over six years. Each member completed an online survey and engaged in a group discussion based on the emergent themes from the survey responses. RESULTS: Our reflections about experiences as a PAC on a large, pan-Canadian research study include three overarching topics (1) what worked well; (2) areas for improvement; and (3) reflections on our overall contribution and impact. Overall, we found the experience positive and experienced personal satisfaction but there were areas where future improvements could be made. These areas include earlier engagement and training in the research process, more frequent communication between the patient committee and the research team, and on-going monitoring regarding the nature of the patient engagement. CONCLUSIONS: Engaging individuals who have experienced the types of events which are the focus of a research study can contribute to the overall relevance of the project. However, intentional efforts are necessary to ensure satisfactory involvement.

RESUMO

Healthcare providers have reported challenges with coordinating care for patients with cancer. Digital technology tools have brought new possibilities for improving care coordination. A web- and text-based asynchronous system (eOncoNote) was implemented in Ottawa, Canada for cancer specialists and primary care providers (PCPs). This study aimed to examine PCPs' experiences of implementing eOncoNote and how access to the system influenced communication between PCPs and cancer specialists. As part of a larger study, we collected and analyzed system usage data and administered an end-of-discussion survey to understand the perceived value of using eOncoNote. eOncoNote data were analyzed for 76 shared patients (33 patients receiving treatment and 43 patients in the survivorship phase). Thirty-nine percent of the PCPs responded to the cancer specialist's initial eOncoNote message and nearly all of those sent only one message. Forty-five percent of the PCPs completed the survey. Most PCPs reported no additional benefits of using eOncoNote and emphasized the need for electronic medical record (EMR) integration. Over half of the PCPs indicated that eOncoNote could be a helpful service if they had questions about a patient. Future research should examine opportunities for EMR integration and whether additional interventions could support communication between PCPs and cancer specialists.

RESUMO

BACKGROUND: Cancer poses a significant global health burden. With advances in screening and treatment, there are now a growing number of cancer survivors with complex needs, requiring the involvement of multiple health care providers. Previous studies have identified problems related to communication and care coordination between primary care providers (PCPs) and cancer specialists. OBJECTIVE: This study aimed to examine whether a web- and text-based asynchronous system (eOncoNote) could facilitate communication between PCPs and cancer specialists (oncologists and oncology nurses) to improve patient-reported continuity of care among patients receiving treatment or posttreatment survivorship care. METHODS: In this pragmatic randomized controlled trial, a total of 173 patients were randomly assigned to either the intervention group (eOncoNote plus usual methods of communication between PCPs and cancer specialists) or a control group (usual communication only), including 104 (60.1%) patients in the survivorship phase (breast and colorectal cancer) and 69 (39.9%) patients in the treatment phase (breast and prostate cancer). The primary outcome was patient-reported team and cross-boundary continuity (Nijmegen Continuity Questionnaire). Secondary outcome measures included the Generalized Anxiety Disorder Screener (GAD-7), Patient Health Questionnaire on Major Depression, and Picker Patient Experience Questionnaire. Patients completed the questionnaires at baseline and at 2 points following randomization. Patients in the treatment phase completed follow-up questionnaires at 1 month and at either 4 months (patients with prostate cancer) or 6 months following randomization (patients with breast cancer). Patients in the survivorship phase completed follow-up questionnaires at 6 months and at 12 months following randomization. RESULTS: The results did not show an intervention effect on the primary outcome of team and cross-boundary continuity of care or on the secondary outcomes of depression and patient experience with their health care. However, there was an intervention effect on anxiety. In the treatment phase, there was a statistically significant difference in the change score from baseline to the 1-month follow-up for GAD-7 (mean difference -2.3; P=.03). In the survivorship phase, there was a statistically significant difference in the change score for GAD-7 between baseline and the 6-month follow-up (mean difference -1.7; P=.03) and between baseline and the 12-month follow-up (mean difference -2.4; P=.004). CONCLUSIONS: PCPs' and cancer specialists' access to eOncoNote is not significantly associated with patient-reported continuity of care. However, PCPs' and cancer specialists' access to the eOncoNote intervention may be a factor in reducing patient anxiety.

RESUMO

BACKGROUND AND OBJECTIVES: The onset of the COVID-19 pandemic severely threatened all aspects of academic family medicine, constituting a crisis. Multiple publications have identified recommendations and documented the creative responses of primary care and academic organizations to address these challenges, but there is little research on how decisions came about. Our objective was to gain insight into the context, process, and nature of family medicine leaders' discussions in pivoting to address a crisis. METHODS: We used a qualitative descriptive design to explore new dimensions of existing concepts. The setting was the academic family medicine department at the University of Toronto. To identify leadership themes, we used the constant comparative method to analyze transcripts of monthly meetings of the departmental executive: three meetings immediately before and three following the declaration of a state emergency in Ontario. RESULTS: Six themes were evident before and after the onset of the pandemic: building capacity in academic family medicine; developing leadership; advancing equity, diversity, and inclusion; learner safety and wellness; striving for excellence; and promoting a supportive and collegial environment. Five themes emerged as specific responses to the crisis: situational awareness; increased multidirectional communication; emotional awareness; innovation in education and patient care; and proactive planning for extended adaptation to the pandemic. CONCLUSION: Existing cultural and organizational approaches formed the foundation for the crisis response, while crisis-specific themes reflected skills and attitudes that are essential in clinical family medicine, including adapting to community needs, communication, and emotional awareness.

RESUMO

Current knowledge creation and mobilization efforts are concentrated in academic institutions. A community-engaged knowledge hub (CEKH) has the potential for transdisciplinary and cross-sectorial collaboration between knowledge producers, mobilizers, and users to develop more relevant and effective research practices as well as to increase community capacity in terms of knowledge production. Objective: To summarize existing original research articles on knowledge hubs or platforms and to identify the benefits, challenges, and ways to address challenges when developing a CEKH. Methods: This study followed a systematic integrative review design. Following a comprehensive search of academic and grey literature databases, we screened 9030 unique articles using predetermined inclusion criteria and identified 20 studies for the final synthesis. We employed thematic analysis to summarize the results. Results: The focus of the majority of these knowledge mobilization hubs was related to health and wellness. Knowledge hubs have a multitude of benefits for the key stakeholders including academics, communities, service providers, and policymakers, including improving dissemination processes, providing more effective community interventions, ensuring informed care, and creating policy assessment tools. Challenges in creating knowledge hubs are generally consistent for all stakeholders, rather than for individual stakeholders, and typically pertain to funding, resources, and conflicting perspectives. As such, strategies to address challenges are also emphasized and should be executed in unison. Conclusions: This study informs the development of a future CEKH through the identification of the benefits, challenges, and strategies to mitigate challenges when developing knowledge hubs. This study addresses a literature gap regarding the comparisons of knowledge hubs and stakeholder experiences.
