RESUMO

BACKGROUND: The expansion of community pharmacy services is one solution to relieve pressure on general practice in the United Kingdom (UK). There is a paucity of research of general practitioners' (GPs') perspectives of quality of care in the community pharmacy sector. The purpose of this study was to explore GPs': Conceptualisation of quality for community pharmacy services, including the management of acute (low acuity) conditions and defining indispensable aspects of the patient experience ('always events') Opinions regarding whether and how to measure quality in the community pharmacy sector METHOD: Semi-structured interviews were conducted with GPs in the UK. GPs were recruited using the snowballing technique and professional networks. Interviews were audio-recorded, transcribed and analysed using an interpretive approach. RESULTS: Interviews were completed with 20 GPs from Scotland (n = 8) and England (n = 12). Multidimensional and inter-related concepts of quality were identified; most dimensions related to patient benefit, as well as impact on GP workload or other health service provision. Interviewees cautioned that "what counts can't always be measured". GPs' expectations of quality often mirrored those of their own sector, but were ambivalent about the adoption of a quality outcome framework-type approach. Pharmacist involvement was expected to ensure quality in the management of 'acute consultations', however, GPs lacked awareness of community pharmacy personnel type, roles and training. Interviewees' perceptions of quality varied by pharmacy type; independent pharmacies were sometimes associated with higher quality service delivery than larger chain organisations. CONCLUSIONS: Quality frameworks for community pharmacy services could be partly informed by GP experience and expectations, but need to be contextual to reflect differences between both settings. The importance of person-centred care, consistency and continuity was emphasised together with the need for competent personnel and privacy of interactions.

RESUMO

The analysis of dental students' clinical production/participation has been used to assess whether a prospective graduate is capable of unsupervised and independent practice (that is, competent to perform that practice). This method and others have inherent biases that may not accurately reflect whether the student has mastered the associated concepts and techniques required for dentistry. The aim of this study was to assess an informatics system that assigned curriculum meta-tags with time-based relative educational value units (ReVUs) to each clinical procedure performed by Medical University of South Carolina (MUSC) students. The system has been used since 1998, but for this study the complete data sets for the MUSC graduating classes of 2007 through 2016 were mapped using microcompetency codes for the dental procedures. In total, 421,494 procedures were formatted and analyzed using software developed to aggregate disparate data sets from clinical activities into a common format for evaluation. The results showed that the ten classes (cohorts) were very consistent with cohort high ReVUs averaging 7,317.1 points, cohort mean ReVUs being 5,180.2 points, and cohort low ReVUs averaging 3,381 points. A detailed analysis of student effort by dental subspecialty found that preventive activities represented 13.4%, patient assessment 32.6%, periodontology 2.8%, restorative dentistry 16.3%, prosthodontics 21.9%, endodontics 6.7%, and oral surgery 5.7% of the total points in the clinical part of the curriculum. In this system, point thresholds can be easily generated to monitor students' progress towards competence for each defined competency and thus assess their progress towards acquiring the skills required for unsupervised, independent practice.

RESUMO

Pituitary tumor-transforming gene 1-binding factor (PTTG1IP; PBF) is a multifunctional glycoprotein, which is overexpressed in a wide range of tumours, and significantly associated with poorer oncological outcomes, such as early tumour recurrence, distant metastasis, extramural vascular invasion and decreased disease-specific survival. PBF transforms NIH 3T3 fibroblasts and induces tumours in nude mice, while mice harbouring transgenic thyroidal PBF expression show hyperplasia and macrofollicular lesions. Our assumption that PBF becomes an oncogene purely through increased expression has been challenged by the recent report of mutations in PBF within the Catalogue of Somatic Mutations in Cancer (COSMIC) database. We therefore sought to determine whether the first 10 PBF missense substitutions in human cancer might be oncogenic. Anisomycin half-life studies revealed that most mutations were associated with reduced protein stability compared to wild-type (WT) PBF. Proliferation assays narrowed our interest to two mutational events which significantly altered cell turnover: C51R and R140W. C51R was mainly confined to the endoplasmic reticulum while R140W was apparent in the Golgi apparatus. Both C51R and R140W lost the capacity to induce cellular migration and significantly reduced cell invasion. Colony formation and soft agar assays demonstrated that, in contrast to WT PBF, both mutants were unable to elicit significant colony formation or anchorage-independent growth. However, C51R and R140W retained the ability to repress radioiodide uptake, a functional hallmark of PBF. Our data reveal new insight into PBF function and confirm that, rather than being oncogenic, mutations in PBF are likely to be passenger effects, with overexpression of PBF the more important aetiological event in human cancer.

RESUMO

BACKGROUND: It is estimated that people with dementia are approximately three times more likely to fracture their hip than sex and age matched controls. A report by the Chartered Society of Physiotherapy found that this population have poor access to rehabilitation as inpatients and in the community. A recent scoping review found a paucity of research in this area, indeed there has been no qualitative research undertaken with physiotherapists. In order to address this evidence gap, the aim of this current study was to explore the experiences of physiotherapists treating this population. METHODS: Semi-structured interviews with physiotherapists were undertaken in order to gain an in-depth understanding of how they manage this population. Physiotherapists were recruited from all over the UK and a purposive sampling strategy was employed. Thematic analysis was utilised. RESULTS: A total of 12 physiotherapists were interviewed, at which stage data saturation was reached as no new themes were emerging. The participants had a broad range of experience both in physical and mental health settings. Analysis identified three separate themes: challenges, "thinking outside the box" and realising potential. Physiotherapists felt significant pressures and challenges regarding many aspects of the management of this population. Mainly this was the result of pressures placed on them by guidelines and targets that may not be achievable or appropriate for those with dementia. The challenges and importance of risk taking was also highlighted for this population with an appreciation that standard treatment techniques may need adapting. "Rehabilitation potential" was highlighted as an important consideration, but challenging to determine. CONCLUSION: Interventions for the management of people with dementia and hip fracture need to consider that a traditional biomedical physiotherapy approach may not be the most appropriate approach to use with this population. However physiotherapists reported feeling pressurised to conform to a biomedical approach.

RESUMO

East Carolina University College of Allied Health Science's Department of Health Services Management program is partnering with Community Care of North Carolina and Access East to transform medical practices and educate students on the Patient-Centered Medical Home (PCMH) model of health care delivery. Why now? The Affordable Care Act (2010) and other health care reform changes brought to the forefront the need to focus on improving the quality of care while lowering the overall cost of care. This article describes the first year of implementation of a PCMH initiative where students in a health services management internship program act as facilitators to assist practices in the PCMH recognition process. Lessons learned were the importance of provider and staff endorsement of the PCMH model. In addition, educational needs, time constraints, electronic health record training, understanding practice workflow, and understanding of the National Committee on Quality Assurance PCMH standards were important aspects of the prerequisite knowledge necessary for success. This article compares the ECU Practicum in Primary Care and the Appalachian State University Practicum in Primary Care to build a best practice model based upon the commonalities and uniqueness of each of the individual university programs and their practice sites.

RESUMO

Patients infected or colonized with carbapenem-resistant Klebsiella pneumoniae (CRKp) are often chronically and acutely ill, which results in substantial mortality unrelated to infection. Therefore, estimating excess mortality due to CRKp infections is challenging. The Consortium on Resistance against Carbapenems in K. pneumoniae (CRACKLE) is a prospective multicenter study. Here, patients in CRACKLE were evaluated at the time of their first CRKp bloodstream infection (BSI), pneumonia or urinary tract infection (UTI). A control cohort of patients with CRKp urinary colonization without CRKp infection was constructed. Excess hospital mortality was defined as mortality in cases after subtracting mortality in controls. In addition, the adjusted hazard ratios (aHR) for time-to-hospital-mortality at 30 days associated with infection compared with colonization were calculated in Cox proportional hazard models. In the study period, 260 patients with CRKp infections were included in the BSI (90 patients), pneumonia (49 patients) and UTI (121 patients) groups, who were compared with 223 controls. All-cause hospital mortality in controls was 12%. Excess hospital mortality was 27% in both patients with BSI and those with pneumonia. Excess hospital mortality was not observed in patients with UTI. In multivariable analyses, BSI and pneumonia compared with controls were associated with aHR of 2.59 (95% CI 1.52-4.50, p <0.001) and 3.44 (95% CI 1.80-6.48, p <0.001), respectively. In conclusion, in patients with CRKp infection, pneumonia is associated with the highest excess hospital mortality. Patients with BSI have slightly lower excess hospital mortality rates, whereas excess hospital mortality was not observed in hospitalized patients with UTI.

RESUMO

OBJECTIVE: Studies indicate needed improvement in clinician communication and patient satisfaction. Motivational interviewing (MI) helps promote patient behavior change and improves satisfaction. In this pilot study, we tested a coaching intervention to teach MI to all clinic staff to improve clinician and patient satisfaction. METHODS: We included four clinics (n=29 staff members). In the intervention clinics (one primary care and one pediatric obesity-focused), we trained all clinic staff in MI through meetings as a group seven times, directly observing clinicians in practice 4-10 times, and providing real-time feedback on MI techniques. In all clinics, we assessed patient satisfaction via anonymous surveys and also assessed clinician burnout and self-rated MI skills. RESULTS: Clinicians in the intervention clinics reported improvements in burnout scores, self-rated MI skills, and perceived cohesion whereas clinicians in the control clinic reported worse scores. Patient satisfaction improved in the intervention clinics more than in the control clinics. CONCLUSION: This is the first study to find some benefit of training an entire clinic staff in MI via a coaching model. PRACTICE IMPLICATIONS: It might help to train staff in MI to improve clinician satisfaction, team cohesion, perceived skills, and patient satisfaction.

RESUMO

This article describes how a facilitation model that included a partnership between a Community Care of North Carolina network and undergraduates at a regional university supported rural primary care practices in transforming their practices to become National Committee for Quality Assurance-recognized patient-centered medical homes. Health care management and preprofessional undergraduate students worked with 14 rural primary care practices to redesign practice processes and complete the patient-centered medical home application. Twelve of the practices participated in the evaluation of the student contribution. A semistructured interview guide containing questions about practice characteristics, student competencies, and the value of the student's contribution to their practice's achievement of patient-centered medical home recognition was used to interview practice managers or their designee. Analysis included item-descriptive statistics and qualitative analysis of narrative content. All 12 participating practices achieved 2011 National Committee for Quality Assurance patient-centered medical home recognition, with 4 practices achieving level 3, 5 practices achieving level 2, and 3 practices achieving level 1. The facilitation model using partnerships between health care agencies and universities might be an option for enhancing a practice's internal capacity for successful transformation and should be explored further.

RESUMO

OBJECTIVE: This report summarizes the closing plenary session of the Association of Chiropractic Colleges Educational Conference-Research Agenda Conference 2014. The purpose of this session was to examine patient-centered medical homes and accountable care organizations from various speakers' viewpoints and to discuss how chiropractic could possibly work within, and successfully contribute to, the changing health care environment. DISCUSSION: The speakers addressed the complex topic of patient-centered medical homes and accountable care organizations and provided suggestions for what leadership strategies the chiropractic profession may need to enhance chiropractic participation and contribution to improving our nation's health. CONCLUSION: There are many factors involved in the complex topic of chiropractic inclusion in health care models. Major themes resulting from this panel included the importance of building relationships with other professionals, demonstrating data and evidence for what is done in chiropractic practice, improving quality of care, improving health of populations, and reducing costs of health care.

RESUMO

OBJECTIVE: To measure the variability of T1ρ relaxation times using CubeQuant, T2 relaxation times using quantitative double echo in steady state (DESS), and normalized sodium signals using 3D cones sodium magnetic resonance imaging (MRI) of knee cartilage in vivo at 3 T. DESIGN: Eight healthy subjects were scanned at 3 T at baseline, 1 day, 5 months, and 1 year. Ten regions of interest (ROIs) of knee cartilage were segmented in the medial and lateral compartments of each subject's knee. T1ρ and T2 relaxation times and normalized sodium signals were measured and the root-mean-square coefficient of variation (CVRMS) was calculated. Intra-subject variability was measured over short, moderate and long-term, as well as intra-observer and inter-observer variability. RESULTS: The average intra-subject CVRMS measurements over short, moderate, and long-term time periods were 4.6%, 6.1%, and 6.0% for the T1ρ measurements, 6.4%, 9.3%, and 10.7% for the T2 measurements and 11.3%, 11.6%, and 12.9% for the sodium measurements, respectively. The average CVRMS measurements for intra-observer and inter-observer segmentation were 3.8% and 5.7% for the T1ρ measurements, 4.7% and 6.7% for the T2 measurements, and 8.1% and 11.4% for the sodium measurements, respectively. CONCLUSIONS: These CVRMS measurements are substantially lower than previously measured changes expected in patients with advanced osteoarthritis compared to healthy volunteers, suggesting that CubeQuant T1ρ, quantitative DESS T2 and 3D cones sodium measurements are sufficiently sensitive for in vivo cartilage studies.

RESUMO

BACKGROUND: Although surgical site infections (SSIs) are known to be associated with increased length of stay (LOS) and additional cost, their impact on the profitability of surgical procedures is unknown. AIM: To determine the clinical and economic burden of SSI over a two-year period and to predict the financial consequences of their elimination. METHODS: SSI surveillance and Patient Level Information and Costing System (PLICS) datasets for patients who underwent major surgical procedures at Plymouth Hospitals NHS Trust between April 2010 and March 2012 were consolidated. The main outcome measures were the attributable postoperative length of stay (LOS), cost, and impact on the margin differential (profitability) of SSI. A secondary outcome was the predicted financial consequence of eliminating all SSIs. FINDINGS: The median additional LOS attributable to SSI was 10 days [95% confidence interval (CI): 7-13 days] and a total of 4694 bed-days were lost over the two-year period. The median additional cost attributable to SSI was £5,239 (95% CI: 4,622-6,719) and the aggregate extra cost over the study period was £2,491,424. After calculating the opportunity cost of eliminating all SSIs that had occurred in the two-year period, the combined overall predicted financial benefit of doing so would have been only £694,007. For seven surgical categories, the hospital would have been financially worse off if it had successfully eliminated all SSIs. CONCLUSION: SSI causes significant clinical and economic burden. Nevertheless the current system of reimbursement provided a financial disincentive to their reduction.

RESUMO

PURPOSE: Transforming a primary care practice into a patient-centered medical home (PCMH) is a resource-dependent endeavor. The objective of our study was to evaluate a facilitation model used to support rural primary care practices during a redesign of their processes to achieve recognition as National Center for Quality Assurance PCMHs. METHODS: The model was a collaboration between Community Care of North Carolina and a local university where undergraduate students worked directly with practices under the guidance of a Community Care of North Carolina PCMH Team. RESULTS: The facilitation model resulted in positive outcomes for both primary care practices and students. CONCLUSIONS: Partnerships between care networks, agencies, payers, or practices and universities or colleges can yield mutual benefits and should be explored.

RESUMO

CONTEXT: The clinical effectiveness of ablative radioiodine treatment of thyroid tumors is limited by the availability of the sodium iodide symporter (NIS) at the plasma membrane (PM) for uptake of ¹³¹I. A significant proportion of well-differentiated thyroid tumors are unable to concentrate sufficient radioiodine for effective therapy, and in other tumor models such as breast tumors, where radioiodine uptake would be an attractive therapeutic option, uptake is insufficient. OBJECTIVE: Pituitary tumor-transforming gene-binding factor (PBF; PTTG1IP) is overexpressed in multiple cancers and significantly decreases NIS expression at the PM. The goal of this study was to identify a method by which PBF repression of NIS may be overcome in human tumors. RESULTS: Here, we identify PBF as a tyrosine phosphoprotein that specifically binds the proto-oncogene tyrosine protein kinase Src in mass spectrometry, glutathione S-transferase pulldown and coimmunoprecipitation assays. Src induction leads to phosphorylation at PBF residue Y174. Abrogation of this residue results in PM retention and a markedly reduced ability to bind NIS. The Src inhibitor PP1 inhibits PBF phosphorylation in multiple cell lines in vitro, including human primary thyroid cells. Of direct clinical importance to the treatment of thyroid cancer, PP1 stimulates iodide uptake by transfected NIS in TPC1 thyroid carcinoma cells and entirely overcomes PBF repression of iodide uptake in human primary thyroid cells. CONCLUSIONS: We propose that targeting PBF phosphorylation at residue Y174 via tyrosine kinase inhibitors may be a novel therapeutic strategy to enhance the efficacy of ablative radioiodine treatment in thyroid and other endocrine and endocrine-related tumors.

RESUMO

Carrying the apoE ε4 allele (E4+ ) is the most important genetic risk for Alzheimer's disease. Unlike non-carriers (E4- ), E4+ seem not to be protected against Alzheimer's disease when consuming fish. We hypothesised that this may be linked to a disturbance in n-3 DHA metabolism in E4+. The aim of the present study was to evaluate [13C]DHA metabolism over 28 d in E4+ v. E4-. A total of forty participants (twenty-six women and fourteen men) received a single oral dose of 40 mg [13C]DHA, and its metabolism was monitored in blood and breath over 28 d. Of the participants, six were E4+ and thirty-four were E4-. In E4+, mean plasma [13C]DHA was 31% lower than that in E4-, and cumulative b-oxidation of [13C]DHA was higher than that in E4- 1­28 d post-dose (P ≤0·05). A genotype x time interaction was detected for cumulative b-oxidation of [13C]DHA (P ≤ 0·01). The whole-body half-life of [13C]DHA was 77% lower in E4+ compared with E4- (P ≤0·01). In E4+ and E4-, the percentage dose of [13C]DHA recovered/h as 13CO2 correlated with [13C]DHA concentration in plasma, but the slope of linear regression was 117% steeper in E4+ compared with E4- (P ≤ 0·05). These results indicate that DHA metabolism is disturbed in E4+, and may help explain why there is no association between DHA levels in plasma and cognition in E4+. However, whether E4+ disturbs the metabolism of 13C-labelled fatty acids other than DHA cannot be deduced from the present study.

RESUMO

Practices contemplating the Patient-Centered Medical Home recognition process are confronted with an arduous task. Perhaps the most palpable constraints are time management combined with staff allocation decisions. Outside consultants can be expensive and disruptive to practice flow. Collaborating with a local college or university's healthcare management or other health career students might be one answer. This article will explore that option.

RESUMO

INTRODUCTION: Most women who have screening mammography and undergo subsequent open biopsy following an indeterminate core biopsy result are eventually found to have benign disease. However, a significant number have malignant disease and the rate of malignancy in such cases may be influenced by various factors. This study examined the effect of the type of screening round (prevalent or incident) on the likelihood of breast cancer being present. METHODS: A total of 199 women who had NHS breast screening mammograms and subsequent indeterminate (B3) core biopsy results followed by excision biopsy over an 11-year period in a single breast screening unit were reviewed. RESULTS: The rate of malignancy following excision of a lesion graded as B3 on core biopsy was 21% for women in the prevalent screening round compared to 33% in subsequent rounds (Fisher's exact test, p=0.038). CONCLUSIONS: The incidence of malignancy associated with a B3 core biopsy result appears to be related to the screening round in which the lesion is detected, being approximately 50% higher in the subsequent incident rounds compared to the initial prevalent round. This finding may be useful in formulating management plans for women who have an indeterminate biopsy result.

RESUMO

AIMS: Radial scars (RS)/complex sclerosing lesions (CSL) are rare, benign breast lesions of unknown aetiology. Associations with breast cancer have been suggested particularly with larger lesions. This study aims to identify the risk of developing subsequent breast cancer after excision of a benign RS/CSL with respect to lesion size and compared to expected rates in the normal UK population. METHODS: A prospective cohort analysis was performed on patients diagnosed with RS/CSL in benign, open breast biopsy specimens over a 20-year period. The rate of subsequent breast cancer development was compared to expected rates in the normal UK population. Subjects were divided into two groups according to lesion size and the rates of subsequent breast cancer compared. RESULTS: 149 women without proliferative breast disease were followed for an average of 68 months. Five women developed subsequent cancer, equating to a rate of 0.84% per year. This compares to 0.32% per year in the normal population (RR 2.6, 95% CI 0.86-6.0). There were two subsequent cancers in the RS group and three subsequent cancers in the CSL group, P = 0.64. CONCLUSIONS: The study finds no evidence to suggest that lesions greater than 10 mm (CSL) have any greater risk of developing cancer after excision than those below 10 mm (RS). Women treated for RS/CSL do not need any additional follow-up beyond routine mammographic breast screening. Additional surveillance should only be performed if there is associated pathology indicating an increased risk of subsequent malignancy.
