RESUMO

Heterogeneous frailty pathobiology might explain the inconsistent associations observed between frailty and lung transplant outcomes. A Subphenotype analysis could refine frailty measurement. In a 3-center pilot cohort study, we measured frailty by the Short Physical Performance Battery, body composition, and serum biomarkers reflecting causes of frailty. We applied latent class modeling for these baseline data. Next, we tested class construct validity with disability, waitlist delisting/death, and early postoperative complications. Among 422 lung transplant candidates, 2 class model fit the best (P = .01). Compared with Subphenotype 1 (n = 333), Subphenotype 2 (n = 89) was characterized by systemic and innate inflammation (higher IL-6, CRP, PTX3, TNF-R1, and IL-1RA); mitochondrial stress (higher GDF-15 and FGF-21); sarcopenia; malnutrition; and lower hemoglobin and walk distance. Subphenotype 2 had a worse disability and higher risk of waitlist delisting or death (hazards ratio: 4.0; 95% confidence interval: 1.8-9.1). Of the total cohort, 257 underwent transplant (Subphenotype 1: 196; Subphenotype 2: 61). Subphenotype 2 had a higher need for take back to the operating room (48% vs 28%; P = .005) and longer posttransplant hospital length of stay (21 days [interquartile range: 14-33] vs 18 days [14-28]; P = .04). Subphenotype 2 trended toward fewer ventilator-free days, needing more postoperative extracorporeal membrane oxygenation and dialysis, and higher need for discharge to rehabilitation facilities (P ≤ .20). In this early phase study, we identified biological frailty Subphenotypes in lung transplant candidates. A hyperinflammatory, sarcopenic Subphenotype seems to be associated with worse clinical outcomes.

RESUMO

Rationale: Primary graft dysfunction (PGD) is the principal cause of early morbidity and mortality after lung transplantation. The lung microbiome has been implicated in later transplantation outcomes but has not been investigated in PGD. Objectives: To define the peritransplant bacterial lung microbiome and relationship to host response and PGD. Methods: This was a single-center prospective cohort study. Airway lavage samples from donor lungs before organ procurement and recipient allografts immediately after implantation underwent bacterial 16S ribosomal ribonucleic acid gene sequencing. Recipient allograft samples were analyzed for cytokines by multiplex array and pepsin by ELISA. Measurements and Main Results: We enrolled 139 transplant subjects and obtained donor lung (n = 109) and recipient allograft (n = 136) samples. Severe PGD (persistent grade 3) developed in 15 subjects over the first 72 hours, and 40 remained without PGD (persistent grade 0). The microbiome of donor lungs differed from healthy lungs, and recipient allograft microbiomes differed from donor lungs. Development of severe PGD was associated with enrichment in the immediate postimplantation lung of oropharyngeal anaerobic taxa, particularly Prevotella. Elevated pepsin, a gastric biomarker, and a hyperinflammatory cytokine profile were present in recipient allografts in severe PGD and strongly correlated with microbiome composition. Together, immediate postimplantation allograft Prevotella/Streptococcus ratio, pepsin, and indicator cytokines were associated with development of severe PGD during the 72-hour post-transplantation period (area under the curve = 0.81). Conclusions: Lung allografts that develop PGD have a microbiome enriched in anaerobic oropharyngeal taxa, elevated gastric pepsin, and hyperinflammatory phenotype. These findings suggest a possible role for peritransplant aspiration in PGD, a potentially actionable mechanism that warrants further investigation.

RESUMO

Delivery of interprofessional education (IPE) initiatives for pre-licensure students is increasingly the norm in health and social care training programmes. This collaborative form of education relies on teachers from various disciplines joining together to facilitate IPE. When IPE programmes first start, goodwill often prevails and facilitators are keen to take part. But as time goes on, retaining the IPE facilitator workforce is challenging. Research was undertaken to explore the experience of IPE facilitators who were part of a New Zealand university-based ten year old IPE programme. The research used a qualitative survey approach. Responses were received from 29% of all those invited to participate. Closed questions were collated and free-text survey responses analyzed using Template Analysis. Three themes and one integrative theme were identified. Themes include facilitators who are recognized, facilitators who are confident, and facilitators who are inspired. Themes were mediated by macro, meso and micro level forces. The cross-cutting integrative theme showed IPE facilitators experienced individual tipping points, with the potential to influence their continued involvement. These tipping points need to be recognized and addressed by those in senior level positions (macro-governance and meso-management), to ensure IPE facilitators continue and IPE programmes remain sustainable.

RESUMO

We evaluated the feasibility, safety, and efficacy of a mHealth-supported physical rehabilitation intervention to treat frailty in a pilot study of 18 lung transplant recipients. Frail recipients were defined by a short physical performance battery (SPPB score ≤7). The primary intervention modality was Aidcube, a customizable rehabilitation mHealth platform. Our primary aims included tolerability, feasibility, and acceptability of use of the platform, and secondary outcomes were changes in SPPB and in scores of physical activity, and disability measured using the Duke Activity Status Index (DASI) and Lung Transplant-Value Life Activities (LT-VLA). Notably, no adverse events were reported. Subjects reported the app was easy to use, usability improved over time, and the app enhanced motivation to engage in rehabilitation. Comments highlighted the complexities of immediate post-transplant rehabilitation, including functional decline, pain, tremor, and fatigue. At the end of the intervention, SPPB scores improved a median of 5 points from a baseline of 4. Physical activity and patient-reported disability also improved. The DASI improved from 4.5 to 19.8 and LT-VLA score improved from 2 to 0.59 at closeout. Overall, utilization of a mHealth rehabilitation platform was safe and well received. Remote rehabilitation was associated with improvements in frailty, physical activity and disability. Future studies should evaluate mHealth treatment modalities in larger-scale randomized trials of lung transplant recipients.

RESUMO

Dysphagia is a common symptom in the general population, and its prevalence increases with patient age. The deterioration of swallowing function has many acute and chronic causes, including cerebrovascular and neuromuscular diseases, radiation, and surgery. In an elderly population, diagnosis and treatment of swallowing abnormalities is a high priority because it improves the patient's quality of life and helps them to avoid medical complications. Fluoroscopic swallowing examinations and modified barium swallow studies are the most used and most reliable diagnostic procedures to evaluate swallowing disorders. Functional anomalies include disturbances of the oral preparatory, oral propulsory, and pharyngeal phases of swallowing as premature spillage from the mouth, nasal regurgitation, delayed initiation of pharyngeal swallowing, incomplete displacement of the hyolaryngeal complex, abnormal epiglottic tilt, incomplete laryngeal closure, and pharyngeal dysmotilities. Anatomic abnormalities of the pharynx include diverticula, benign strictures, and tumors. The abnormalities diagnosed on the basis of fluoroscopic examination have a variety of treatment strategies, and the choice of treatment depends on the cause of the anomaly and its pathophysiologic characteristics. The radiologist's interpretation of these characteristics is crucial to therapeutic decision making and achieving the best patient outcomes.

RESUMO

BACKGROUND: Temperament and personality traits, including negative emotionality/neuroticism, may represent risk factors for eating disorders. Further, risk factors may differ by sex. We examined longitudinal temperament/personality pathways of risk for purging and binge eating in youth stratified by sex using data from a large-scale prospective study. METHODS: Temperament, borderline personality features, sensation seeking, 'big five' personality factors, and depressive symptoms were measured at five time points from early childhood to adolescence in 5812 adolescents (3215 females; 2597 males) in the Avon Longitudinal Study of Parents and Children. We conducted univariate analyses with these predictors of binge eating and purging at 14 and 16 years for total and sex-stratified samples. We used structural equation modeling (SEM) to fit data to a path analysis model of hypothesized associations. RESULTS: Of the total sample, 12.54% engaged in binge eating and 7.05% in purging by 16 years. Prevalence was much greater and increased dramatically for females from 14 years (7.50% binge eating; 2.40% purging) to 16 years (15.80% binge eating; 9.50% purging). For both sexes, borderline personality, depressive symptoms and lower emotional stability predicted eating disorder behaviors; sensation seeking and conscientiousness were also significant predictors for females. SEM identified an 'emotional instability' pathway for females from early childhood into adolescence (RMSEA = 0.025, TLI = 0.937 and CFI = 0.970). CONCLUSIONS: Binge eating and purging are common in female and male adolescents. Early temperament/personality factors related to difficulty regulating emotions were predictive of later adolescent eating disorder behaviors. Results have important clinical implications for eating disorder prevention and intervention.

RESUMO

OBJECTIVE: To determine whether parental resilience, measured at ICU admission, is associated with parent-reported symptoms of depression, anxiety, posttraumatic stress, and satisfaction with ICU care 3-5 weeks following ICU discharge. DESIGN: Planned prospective, observational study nested in a randomized comparative trial. SETTING: PICUs and cardiac ICUs in two, free-standing metropolitan area children's hospitals. PARTICIPANTS: English- and Spanish-speaking parents whose children were younger than 18 years old and had anticipated ICU stay of greater than 24 hours or Pediatric Index of Mortality score of greater than or equal to 4 at the time of consent. All ICU admissions were screened for inclusion. Of 4,251 admissions reviewed, 1,360 were eligible. Five hundred families were approached and 382 enrolled. Two hundred thirty-two parents from 210 families with complete data were included in analysis. INTERVENTIONS: All participating parents completed the Connor-Davidson Resilience Scale at the time of consent and outcome measures 3-5 weeks after ICU discharge. MEASUREMENTS AND MAIN RESULTS: All parents completed the Patient-Reported Outcome Measurement Information System Short Forms 8a for Depression and Anxiety, Impact of Event Scale-Revised for posttraumatic stress, and Pediatric Family Satisfaction-ICU 24 for parental satisfaction 3-5 weeks after ICU discharge. Higher parental resilience was associated with fewer symptoms of depression, anxiety, and posttraumatic stress in the final model (all p < 0.0001). Shorter length of stay, early mechanical ventilation, Latino ethnicity, and lower illness severity (both objective and parental perceptions) were associated with less morbidity in some or all measured mental health outcomes. CONCLUSIONS: Higher parental resilience is associated with fewer reported symptoms of anxiety, depression, and posttraumatic stress 3-5 weeks after ICU discharge. Parental resilience may impact parental post-ICU psychological morbidity. Measuring parental resilience could be one approach to identify parents at risk for post-ICU psychological morbidity. Future research into the impact of interventions designed to boost parental resilience is warranted.

RESUMO

OBJECTIVES: Communication breakdowns in PICUs contribute to inadequate parent support and poor post-PICU parent outcomes. No interventions supporting communication have demonstrated improvements in parental satisfaction or psychologic morbidity. We compared parent-reported outcomes from parents receiving a navigator-based parent support intervention (PICU Supports) with those from parents receiving an informational brochure. DESIGN: Patient-level, randomized trial. SETTING: Two university-based, tertiary-care children's hospital PICUs. PARTICIPANTS: Parents of patients requiring more than 24 hours in the PICU. INTERVENTIONS: PICU Supports included adding a trained navigator to the patient's healthcare team. Trained navigators met with parents and team members to assess and address communication, decision-making, emotional, informational, and discharge or end-of-life care needs; offered weekly family meetings; and did a post-PICU discharge parent check-in. The comparator arm received an informational brochure providing information about PICU procedures, terms, and healthcare providers. MEASUREMENTS AND MAIN RESULTS: The primary outcome was percentage of "excellent" responses to the Pediatric Family Satisfaction in the ICU 24 decision-making domain obtained 3-5 weeks following PICU discharge. Secondary outcomes included parental psychologic and physical morbidity and perceptions of team communication. We enrolled 382 families: 190 received PICU Supports, and 192 received the brochure. Fifty-seven percent (216/382) completed the 3-5 weeks post-PICU discharge survey. The mean percentage of excellent responses to the Pediatric Family Satisfaction in the ICU 24 decision-making items was 60.4% for PICU Supports versus 56.1% for the brochure (estimate, 3.57; SE, 4.53; 95% CI, -5.77 to 12.90; p = 0.44). Differences in secondary outcomes were not statistically significant. Most parents (91.1%; 113/124) described PICU Supports as "extremely" or "somewhat" helpful. CONCLUSIONS: Parents who received PICU Supports rated the intervention positively. Differences in decision-making satisfaction scores between those receiving PICU Supports and a brochure were not statistically significant. Interventions like PICU Supports should be evaluated in larger studies employing enhanced recruitment and retention of subjects.

RESUMO

Interprofessional education (IPE) programs for pre-registration health science students are largely offered within one institution including different schools or faculties. Sometimes in small or regional institutions where there are limited student numbers or few professional training programs, or where larger institutions do not offer particular professional programs, it may be necessary to partner with other institutions to offer IPE. This study sought to explore teacher perspectives of forming inter-institutional partnerships to deliver IPE, in particular, to identify the elements that influence the formation of partnerships. An interpretive descriptive approach was used to thematically analyze data from three focus groups with teachers (n = 21) working in three different partnerships to deliver IPE to students in Wellington, New Zealand. Two main themes were identified which enabled the development of a model of partnership, with a continuum of complexity depending on whether institutions were on the same page and whether the partnership formed to join an existing IPE program or to create a new IPE program. Forming inter-institution partnerships is a pragmatic solution to providing IPE with benefits to all taking part. Our work showed that time, effort, working with complexity, and ability to stay on the same page are necessary elements for building successful partnerships and all need to be taken into account when planning inter-institution partnerships.

RESUMO

One of the central challenges of transplantation is the development of alloreactivity despite the use of multiagent immunoprophylaxis. Effective control of this immune suppression-resistant T-cell activation represents one of the key unmet needs in the fields of both solid-organ and hematopoietic stem cell transplant (HCT). To address this unmet need, we have used a highly translational nonhuman primate (NHP) model to interrogate the transcriptional signature of T cells during breakthrough acute graft-versus-host disease (GVHD) that occurs in the setting of clinically relevant immune suppression and compared this to the hyperacute GVHD, which develops in unprophylaxed or suboptimally prophylaxed transplant recipients. Our results demonstrate the complex character of the alloreactivity that develops during ongoing immunoprophylaxis and identify 3 key transcriptional hallmarks of breakthrough acute GVHD that are not observed in hyperacute GVHD: (1) T-cell persistence rather than proliferation, (2) evidence for highly inflammatory transcriptional programming, and (3) skewing toward a T helper (Th)/T cytotoxic (Tc)17 transcriptional program. Importantly, the gene coexpression profiles from human HCT recipients who developed GVHD while on immunosuppressive prophylactic agents recapitulated the patterns observed in NHP, and demonstrated an evolution toward a more inflammatory signature as time posttransplant progressed. These results strongly implicate the evolution of both inflammatory and interleukin 17-based immune pathogenesis in GVHD, and provide the first map of this evolving process in primates in the setting of clinically relevant immunomodulation. This map represents a novel transcriptomic resource for further systems-based efforts to study the breakthrough alloresponse that occurs posttransplant despite immunoprophylaxis and to develop evidence-based strategies for effective treatment of this disease.

RESUMO

A neurocognitive profile characterized by problems in set shifting, executive functioning, and central coherence may pre-date and maintain anorexia nervosa (AN). To test this pattern as a possible endophenotype for AN, 10 youth with current AN, 14 healthy youth, and their biological parents, participated in a neuropsychological battery. Youth with AN demonstrated significantly weaker central coherence, related to enhanced detail-focused processing. Youth with AN and their parents demonstrated significantly greater psychopathology relative to controls, and youth-parent scores were significantly correlated. The study, limited by a small sample size, found little evidence supporting a neuropsychological endophenotype for AN. Identifying a neurocognitive profile for children and adolescents with AN has important implications for the treatment of young patients.

RESUMO

Intolerance of uncertainty is an empirically supported transdiagnostic construct that may have relevance in understanding eating disorders. We conducted a meta-analysis and systematic review of intolerance of uncertainty in eating disorders using Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. We calculated random-effects standardised mean differences (SMD) for studies utilising the Intolerance of Uncertainty Scale (IUS) and summarised additional studies descriptively. Women with eating disorders have significantly higher IUS scores compared with healthy controls (SMD = 1.90; 95% C.I. 1.24 to 2.56; p < 0.001). Post hoc meta-analysis revealed significant differences when comparing women with anorexia nervosa with controls (SMD = 2.16; 95% C.I. 1.14 to 3.18; p < 0.001) and women with bulimia nervosa with controls (SMD = 2.03; 95% C.I. 1.30 to 2.75; p < 0.001). Our synthesis of findings suggests that intolerance of uncertainty may represent a vulnerability and maintenance factor for eating disorders and potential target of cognitive, behavioural, interoceptive and affective symptoms.

RESUMO

The clinical significance of Alloscardovia omnincolens in the urinary tract has not been thoroughly evaluated. In this study, 15 patients with A. omnincolens present in their urine cultures were identified. A. omnincolens is only rarely associated with urinary tract symptoms and in some patients may play a commensal role.

RESUMO

OBJECTIVES: To compare the sensitivity and specificity of different classification criteria for gout in early and established disease. METHODS: This was a cross-sectional study of consecutive rheumatology clinic patients with joint swelling in which gout was defined by presence or absence of monosodium urate crystals as observed by a certified examiner at presentation. Early disease was defined as patient-reported onset of symptoms of 2 years or less. RESULTS: Data from 983 patients were collected and gout was present in 509 (52%). Early disease was present in 144 gout cases and 228 non-cases. Sensitivity across criteria was better in established disease (95.3% vs 84.1%, p<0.001) and specificity was better in early disease (79.9% vs 52.5%, p<0.001). The overall best performing clinical criteria were the Rome criteria with sensitivity/specificity in early and established disease of 60.3%/84.4% and 86.4%/63.6%. Criteria not requiring synovial fluid analysis had sensitivity and specificity of less than 80% in early and established disease. CONCLUSIONS: Existing classification criteria for gout have sensitivity of over 80% in early and established disease but currently available criteria that do not require synovial fluid analysis have inadequate specificity especially later in the disease. Classification criteria for gout with better specificity are required, although the findings should be cautiously applied to non-rheumatology clinic populations.

RESUMO

BACKGROUND: Many health researchers are clinicians. Dual-role experiences are common for clinician-researchers in research involving patient-participants, even if not their own patients. To extend the existing body of literature on why dual-role is experienced, we aimed to develop a typology of common catalysts for dual-role experiences to help clinician-researchers plan and implement methodologically and ethically sound research. METHODS: Systematic searching of Medline, CINAHL, PsycINFO, Embase and Scopus (inception to 28.07.2014) for primary studies or first-person reflexive reports of clinician-researchers' dual-role experiences, supplemented by reference list checking and Google Scholar scoping searches. Included articles were loaded in NVivo for analysis. The coding was focused on how dual-role was evidenced for the clinician-researchers in research involving patients. Procedures were completed by one researcher (MB) and independently cross-checked by another (JHS). All authors contributed to extensive discussions to resolve all disagreements about initial coding and verify the final themes. RESULTS: Database searching located 7135 records, resulting in 29 included studies, with the addition of 7 studies through reference checks and scoping searches. Two overarching themes described the most common catalysts for dual-role experiences - ways a research role can involve patterns of behaviour typical of a clinical role, and the developing connection that starts to resemble a clinician-patient relationship. Five subthemes encapsulated the clinical patterns commonly repeated in research settings (clinical queries, perceived agenda, helping hands, uninvited clinical expert, and research or therapy) and five subthemes described concerns about the researcher-participant relationship (clinical assumptions, suspicion and holding back, revelations, over-identification, and manipulation). Clinician-researchers use their clinical skills in health research in ways that set up a relationship resembling that of clinician-patient. Clinicians' ingrained orientation to patients' needs can be in tension with their research role, and can set up ethical and methodological challenges. CONCLUSION: The typology we developed outlines the common ways dual-role is experienced in research involving clinician-researchers and patient-participants, and perhaps the inevitability of the experience given the primacy accorded to patient well-being. The typology offers clinician-researchers a framework for grappling with the ethical and methodological implications of dual-role throughout the research process, including planning, implementation, monitoring and reporting.

RESUMO

RATIONALE: Frailty is associated with morbidity and mortality in abdominal organ transplantation but has not been examined in lung transplantation. OBJECTIVES: To examine the construct and predictive validity of frailty phenotypes in lung transplant candidates. METHODS: In a multicenter prospective cohort, we measured frailty with the Fried Frailty Phenotype (FFP) and Short Physical Performance Battery (SPPB). We evaluated construct validity through comparisons with conceptually related factors. In a nested case-control study of frail and nonfrail subjects, we measured serum IL-6, tumor necrosis factor receptor 1, insulin-like growth factor I, and leptin. We estimated the association between frailty and disability using the Lung Transplant Valued Life Activities disability scale. We estimated the association between frailty and risk of delisting or death before transplant using multivariate logistic and Cox models, respectively. MEASUREMENTS AND MAIN RESULTS: Of 395 subjects, 354 completed FFP assessments and 262 completed SPPB assessments; 28% were frail by FFP (95% confidence interval [CI], 24-33%) and 10% based on the SPPB (95% CI, 7-14%). By either measure, frailty correlated more strongly with exercise capacity and grip strength than with lung function. Frail subjects tended to have higher plasma IL-6 and tumor necrosis factor receptor 1 and lower insulin-like growth factor I and leptin. Frailty by either measure was associated with greater disability. After adjusting for age, sex, diagnosis, and transplant center, both FFP and SPPB were associated with increased risk of delisting or death before lung transplant. For every 1-point worsening in score, hazard ratios were 1.30 (95% CI, 1.01-1.67) for FFP and 1.53 (95% CI, 1.19-1.59) for SPPB. CONCLUSIONS: Frailty is prevalent among lung transplant candidates and is independently associated with greater disability and an increased risk of delisting or death.

RESUMO

OBJECTIVE: Existing criteria for the classification of gout have suboptimal sensitivity and/or specificity, and were developed at a time when advanced imaging was not available. The current effort was undertaken to develop new classification criteria for gout. METHODS: An international group of investigators, supported by the American College of Rheumatology and the European League Against Rheumatism, conducted a systematic review of the literature on advanced imaging of gout, a diagnostic study in which the presence of monosodium urate monohydrate (MSU) crystals in synovial fluid or tophus was the gold standard, a ranking exercise of paper patient cases, and a multi-criterion decision analysis exercise. These data formed the basis for developing the classification criteria, which were tested in an independent data set. RESULTS: The entry criterion for the new classification criteria requires the occurrence of at least one episode of peripheral joint or bursal swelling, pain, or tenderness. The presence of MSU crystals in a symptomatic joint/bursa (ie, synovial fluid) or in a tophus is a sufficient criterion for classification of the subject as having gout, and does not require further scoring. The domains of the new classification criteria include clinical (pattern of joint/bursa involvement, characteristics and time course of symptomatic episodes), laboratory (serum urate, MSU-negative synovial fluid aspirate), and imaging (double-contour sign on ultrasound or urate on dual-energy CT, radiographic gout-related erosion). The sensitivity and specificity of the criteria are high (92% and 89%, respectively). CONCLUSIONS: The new classification criteria, developed using a data-driven and decision-analytic approach, have excellent performance characteristics and incorporate current state-of-the-art evidence regarding gout.

RESUMO

BACKGROUND: Patients with functional motor disorder (FMD) including weakness and paralysis are commonly referred to physiotherapists. There is growing evidence that physiotherapy is an effective treatment, but the existing literature has limited explanations of what physiotherapy should consist of and there are insufficient data to produce evidence-based guidelines. We aim to address this issue by presenting recommendations for physiotherapy treatment. METHODS: A meeting was held between physiotherapists, neurologists and neuropsychiatrists, all with extensive experience in treating FMD. A set of consensus recommendations were produced based on existing evidence and experience. RESULTS: We recommend that physiotherapy treatment is based on a biopsychosocial aetiological framework. Treatment should address illness beliefs, self-directed attention and abnormal habitual movement patterns through a process of education, movement retraining and self-management strategies within a positive and non-judgemental context. We provide specific examples of these strategies for different symptoms. CONCLUSIONS: Physiotherapy has a key role in the multidisciplinary management of patients with FMD. There appear to be specific physiotherapy techniques which are useful in FMD and which are amenable to and require prospective evaluation. The processes involved in referral, treatment and discharge from physiotherapy should be considered carefully as a part of a treatment package.

RESUMO

The most extensively researched form of psychotherapy over the last 10 years, cognitive behavioural therapy (CBT), has recently been promoted in health visiting practice. Health visitors, frontline practitioners for the majority of women with postnatal depression (PND), stand between the use of antidepressants for PND on the one hand where compliance is not good and the potential to offer a practical alternative using cognitive behavioural techniques on the other. The aim of this study was to examine how health visitors understand the concept of CBT and envisage its implementation in practice with regard to the treatment and management of PND. A qualitative research methodology using a phenomenological approach was adopted to analyse transcripts from two semi-structured focus group interviews with nine health visitors about their work with PND and CBT. The findings demonstrated that health visitors do not want to be known as 'frontline' professionals in the delivery of CBT to treat PND as this would imply 'counsellor'--a diversion from their professional identity and unique role. However, they wanted to be equipped with more than just introductory basic assessment and treatment techniques in CBT to deliver a pragmatic, psycho-educational approach to PND in four to eight home sessions.

RESUMO

OBJECTIVE: Identify areas of consensus on integrating lifestyle medicine (LM) into primary care to achieve optimal outcomes. METHODS: Experts in both LM and primary care followed an a priori protocol for developing consensus statements. Using an iterative, online process, panel members expressed levels of agreement with statements, resulting in classification as consensus, near consensus, or no consensus. RESULTS: The panel identified 124 candidate statements addressing: (1) Integration into Primary Care, (2) Delivery Models, (3) Provider Education, (4) Evidence-base for LM, (5) Vital Signs, (6) Treatment, (7) Resource Referral and Reimbursement, (8) Patient, Family, and Community Involvement; Shared Decision-Making, (9) Social Determinants of Health and Health Equity, and (10) Barriers to LM. After three iterations of an online Delphi survey, statement revisions, and removal of duplicative statements, 65 statements met criteria for consensus, 24 for near consensus, and 35 for no consensus. Consensus was reached on key topics that included LM being recognized as an essential component of primary care in patients of all ages, including LM as a foundational element of health professional education. CONCLUSION: The practice of LM in primary care can be strengthened by applying these statements to improve quality of care, inform policy, and identify areas for future research.
