RESUMO

BACKGROUND: Internationally, community pharmacy models of care have been moving away from a focus on dispensing to extended, clinically-focused roles for pharmacists. OBJECTIVES: To identify how community pharmacy strategies were being implemented in Aotearoa New Zealand; how changes were expected to influence health and health system outcomes; what extended services were being delivered; the responses of pharmacists, other health professionals and consumers to these developments; and the contexts and mechanisms supporting the successful implementation of new community pharmacy services. METHODS: A realist evaluation methodology was employed, to explore a complex policy intervention. Realist evaluation explores the contexts (C) within which initiatives are introduced and identifies the mechanisms (M) triggered by different contexts to produce outcomes (O). Realist evaluation processes iteratively develop, test, and refine CMO configurations. In this study, initial programme theories were developed through key government and professional policy documents, then refined through key informant interviews, a survey and interviews with pharmacists and intern (pre-registration) pharmacists, and finally, 10 case studies of diverse community pharmacies. RESULTS: Four intermediate health service outcomes were identified: development of extended community pharmacist services; consumers using extended community pharmacist services; more integrated, collaborative primary health care services; and a fit-for-purpose community pharmacy workforce. Enabling and constraining contexts are detailed for each outcome, along with the mechanisms that they trigger (or inhibit). CONCLUSIONS: There are wide-ranging and disparate levers to support the further development of extended community pharmacy services. These include aligning funding with desired services, undergraduate educators and professional leaders setting expectations for the pharmacists' role in practice, and the availability of sufficient funding and time for both specific extended service accreditation and broader postgraduate training. However, no simple "fix" can be universally applied internationally, nor even in pharmacies within a single jurisdiction, to facilitate service development.

RESUMO

Introduction New Zealand pharmacists must complete a joint prescribing course offered by Otago and Auckland universities only, to be qualified as pharmacist prescribers. Aim To identify knowledge and perceptions of New Zealand registered pharmacists, who are not pharmacist prescribers, on: pharmacist prescribing roles, courses and perceived barriers and facilitators to course uptake. Methods Participants comprised registered practising New Zealand pharmacists (n = 4025), across all New Zealand regions. Invitations to participate in a questionnaire survey were sent in March 2021. Data were analysed using thematic analysis and descriptive statistics. Results The response rate was 12% (482/4025), with 94% community pharmacists. Almost two-thirds (65%) had over 10 years of working experience. Nearly all (95%) agreed that pharmacist prescribing would improve healthcare delivery in New Zealand. Most reported that barriers to pharmacist prescribing course uptake were funding, lack of institutional support, up-to-date pharmacological/pharmaceutical knowledge, and 2 years of experience in collaborative health team prerequisites for enrolment, finding medical supervisors, and lack of remuneration for prescribing roles. Discussion Pharmacist prescribing in New Zealand is still in its growing phase. Optimising uptake of prescribing courses and role requires a multi-level approach including all stakeholders. Government/policymakers should consider pharmacist prescribing training and remuneration in their funding plans. Employing institutions should provide required time and human resources (staff backfills). Training providers should consider methods of course delivery and assessment that are suitable for trainees in full-time employment.

RESUMO

BACKGROUND: Tranexamic acid (TXA) is increasingly being used to prevent hemorrhagic complications after dermatologic surgery. Interpolated flap repairs following Mohs micrographic surgery are at risk for increased bleeding events and unplanned health care utilization, particularly among patients on antithrombotic medication. OBJECTIVE: To assess bleeding events after interpolated flap repair in patients receiving TXA compared with those who did not. MATERIALS AND METHODS: A retrospective review identified interpolated flap repairs in a 5-year period. Hemorrhagic complications were analyzed, defined as major bleeding events, which included all unplanned medical visits, and minor bleeding events, which included any unplanned patient phone calls or messages through electronic medical record. RESULTS: One hundred fifteen patients had interpolated flap repair during the 5-year period, of which 21 (18.3%) received TXA postprocedure. Twenty-seven bleeding events were identified in the non-TXA group compared with 1 event in the TXA-treated group. Patients who received TXA were less likely to have had a bleeding event (28.7% vs 4.8%, p < .01). CONCLUSION: Patients undergoing interpolation flap repair were less likely to experience a bleeding event after subcutaneous injection of TXA.

RESUMO

BACKGROUND: Supraventricular tachycardia (SVT) is a relatively frequent diagnosis in the pediatric emergency department (ED). However, there are no consensus guidelines for ED disposition, and there are limited data on ED outcomes. Better understanding of those who are admitted or have antiarrhythmic medication changes may avoid potentially unnecessary transfers or admissions. Our objective was to identify patient factors associated with discharge from the emergency department without medication initiation or modification after management of SVT in the pediatric ED. DESIGN/METHODS: A retrospective review of children aged 0-18 years seen in the emergency department for SVT was conducted using electronic medical record data over a ten-year period at a single academic tertiary children's hospital. Patients with congenital cardiac disease or prior cardiac surgeries were excluded. Multivariable logistic regression analysis was used to determine association between patient factors of interest and the primary outcome of admission and secondary outcome of change to antiarrhythmic medications. RESULTS: We analyzed 197 patients encounters. The mean age was 7 years. Of these 104 (52.8%) were admitted to the hospital or discharged with antiarrhythmic medication changes. This primary outcome was associated with younger age (aOR 0.77, 95% CI 0.67-0.86), history of pre-excitation (aOR 5.82, 95% CI 2.01-18.8), intercurrent illness (aOR 3.75, 95% CI 1.27-12.1), number of adenosine doses prior to arrival (aOR 5.45, 95% CI 1.55-22.3), and in-person cardiology consultation (aOR 6.42, 95% CI 2.43-19.4). CONCLUSIONS: Nearly half of children treated in a pediatric ED for SVT are discharged without changes in medications. We identified patient factors associated with hospital admission or antiarrhythmic medication changes. These factors represent high value care and can be assessed when considering transfer from a referring facility. Risk stratification using these patient characteristics may reduce potentially avoidable transfers and admissions.

RESUMO

Objective: The Transitional Care Nursing Service was a 2-year proof-of-concept trial exploring local health system readiness for incorporating integrated, person-centred models of care into existing health service structures within a provincial New Zealand context. Improved patient experience remains a priority in international and local healthcare policy directives. This qualitative study aimed to investigate patient experience by exploring the effectiveness of this integrated care person-centred service from the patients' perspective. Methods: Qualitative, semistructured, face-to-face interviews with 12 patients purposively sampled to achieve maximum variation of patient characteristics within the trial cohort. Interviews were audio-recorded and transcribed verbatim before analysing the data using thematic analysis supported by a general inductive approach. Results: Findings demonstrated that patient interactions with the transitional care nurse positively influenced patient experience, self-reported outcomes and quality of life following hospitalisation and during the transition period between hospital and home. Participants perceived the nurse to be highly skilled in displaying kindness, empathy, accessibility and responsiveness, and communication skills with participants and their families. They perceived that their interactions with this individual team member working from an integrated care paradigm had a positive impact on their overall experience of care and recovery. Conclusion: This study supports the use of integrated care principles to deliver person-centred care. The findings emphasise the need to place kindness, compassion and respect at the heart of care delivered to patients, and suggest these core values are an essential factor in improving patient experience and thus the effectiveness of our healthcare systems.

RESUMO

INTRODUCTION During the coronavirus disease 2019 (COVID-19) pandemic lockdown in New Zealand in March 2020, there was a rapid shift to virtual consultations in primary care. This change was supported by system adjustments to enable electronic transmission of prescriptions without a handwritten signature if they met certain security criteria. International research suggests potential for unintended consequences with such changes, so it is important to understand the effect on professional practice in New Zealand general practice and community pharmacy. AIM The purpose of this study was to undertake a preliminary exploration of the experiences of New Zealand general practitioners and community pharmacists when prescriptions are transmitted electronically directly from prescriber to pharmacy. METHODS Semi-structured interviews with a purposive sample of four pharmacists and four general practitioners gathered qualitative data about their experiences of the shift to electronic transmission of prescriptions. Participants' perceptions of effect on professional workflow, interprofessional interactions between general practitioners and pharmacists, and interactions with patients were explored. Interviews were audio-recorded, and the data analysed thematically using an inductive approach. RESULTS Four themes were identified: workflow transformation; mixed impact on interactions with patients; juggling timing and expectations; and new avenues for interprofessional communication (with some cul-de-sacs). DISCUSSION Both general practitioners and pharmacists experienced transformational changes to workflow. This was positive for general practitioners due to saved time and increased work flexibility. Pharmacists noted potential benefits but also some challenges. To fully reap teamwork benefits, more work is needed on managing the timing issues and patient expectations, and to refine the new modes of communication between health-care practitioners.

RESUMO

BACKGROUND AND CONTEXT Globally, the coronavirus disease 2019 (COVID-19) pandemic has highlighted the need for better interprofessional collaboration and teamwork. When disciplines have worked together to undertake testing, deliver care and administer vaccines, progress against COVID-19 has been made. Yet, teamwork has often not happened, wasting precious resources and stretching health-care workforces. Continuing to train health professionals during the pandemic is challenging, particularly delivering interprofessional education that often uses face-to-face delivery methods to optimise interactional learning. Yet, continuing to offer interprofessional education throughout the pandemic is critical to ensure a collaboration-ready health workforce. One example is continuing the established INVOLVE (Interprofessional Visits to Learn Interprofessional Values through Patient Experience) interprofessional education initiative. ASSESSMENT OF PROBLEM Educators have not always prioritised interprofessional education during the pandemic, despite its immediate and long-term benefits. The INVOLVE interprofessional education initiative, usually delivered face-to-face, was at risk of cancellation. RESULTS A quality improvement analysis of the strategies used to continue INVOLVE demonstrated that it is possible to deliver interprofessional education within the constraints of a pandemic by using innovative online and hybrid educational strategies. Educators and students demonstrated flexibility in responding to the sudden changes in teaching and learning modalities. STRATEGIES When pandemic alert levels change, interprofessional educators and administrators can now choose from a repertoire of teaching approaches. LESSONS Four key lessons have improved the performance and resilience of INVOLVE: hold the vision to continue interprofessional education; be nimble; use technology appropriately; and there will be silver linings and unexpected benefits to the changes.

RESUMO

SARS-CoV-2 viral attachment and entry into host cells is mediated by a direct interaction between viral spike glycoproteins and membrane bound angiotensin-converting enzyme 2 (ACE2). The receptor binding motif (RBM), located within the S1 subunit of the spike protein, incorporates the majority of known ACE2 contact residues responsible for high affinity binding and associated virulence. Observation of existing crystal structures of the SARS-CoV-2 receptor binding domain (SRBD)-ACE2 interface, combined with peptide array screening, allowed us to define a series of linear native RBM-derived peptides that were selected as potential antiviral decoy sequences with the aim of directly binding ACE2 and attenuating viral cell entry. RBM1 (16mer): S443KVGGNYNYLYRLFRK458, RBM2A (25mer): E484GFNCYFPLQSYGFQPTNGVGYQPY508, RBM2B (20mer): F456NCYFPLQSYGFQPTNGVGY505 and RBM2A-Sc (25mer): NYGLQGSPFGYQETPYPFCNFVQYG. Data from fluorescence polarisation experiments suggested direct binding between RBM peptides and ACE2, with binding affinities ranging from the high nM to low µM range (Kd = 0.207-1.206 µM). However, the RBM peptides demonstrated only modest effects in preventing SRBD internalisation and showed no antiviral activity in a spike protein trimer neutralisation assay. The RBM peptides also failed to suppress S1-protein mediated inflammation in an endogenously expressing ACE2 human cell line. We conclude that linear native RBM-derived peptides are unable to outcompete viral spike protein for binding to ACE2 and therefore represent a suboptimal approach to inhibiting SARS-CoV-2 viral cell entry. These findings reinforce the notion that larger biologics (such as soluble ACE2, 'miniproteins', nanobodies and antibodies) are likely better suited as SARS-CoV-2 cell-entry inhibitors than short-sequence linear peptides.

RESUMO

BACKGROUND: Changes in pharmacy models of care, services and funding have been occurring internationally, moving away from the traditional dispensing role to more extended patient-facing roles utilising pharmacists' clinical skills. This study aimed to identify the extended services offered by community pharmacy in Aotearoa New Zealand and the barriers and facilitators to extended services provision. The study is unique in that it includes intern (pre-registration) pharmacists. METHODS: An online survey, conducted in 2018, of all pharmacists and intern (pre-registration) pharmacists working in a community pharmacy. Data were analysed using descriptive statistics and regression analyses. RESULTS: The results are based on replies from 553 community pharmacists and 59 intern pharmacists (response rate: 19 and 26% respectively). Both pharmacists (83%) and interns (85%) want to work at the top of their scope of practice. Wide variation exists in the specific services individual pharmacists offer. Most pharmacists were accredited to supply the emergency contraceptive pill (95%), sildenafil for erectile dysfunction (86%) and trimethoprim for uncomplicated urinary tract infection (85%). Fewer were able to immunise (34%) or to supply selected oral contraceptives (44%). Just under a quarter could provide a Medicines Use Review (MUR) or Community Pharmacy Anticoagulation Management Service (CPAMS). Of the pharmacists not already accredited, 85% intended to gain accreditation to supply selected oral contraceptives, 40% to become vaccinators, 37% to offer CPAMS and 30% MUR. Interns expressed strong interest in becoming accredited for all extended services. Poisson regression analyses showed key factors supporting the likelihood of providing extended services were owner and management support and appropriate space and equipment. Being excited about the opportunities in community pharmacy, having employer funding and time for training and sufficient support staff were also statistically significant. CONCLUSIONS: Pharmacists need time and a supportive management structure to enable them to deliver extended services. Health policy with a greater strategic emphasis on funding services and pharmacist training, and developing technician support roles, will help to minimise or eliminate some of the barriers to role expansion both in Aotearoa New Zealand and internationally.

RESUMO

BACKGROUND: Health services internationally have been compelled to change their methods of service delivery in response to the global COVID-19 pandemic, to mitigate the spread of infection amongst health professionals and patients. In Aotearoa/New Zealand, widespread electronic delivery of prescriptions (e-prescribing) was enabled. The aim of the research was to explore patients' experiences of how lockdown, changes to prescribing and the interface between general practices and community pharmacy affected access to prescription medications. METHOD: The research employed a mixed-method approach. This included an online survey (n = 1,010) and in-depth interviews with a subset of survey respondents (n = 38) during the first COVID-19 lockdown (March-May 2020). Respondents were recruited through a snowballing approach, starting with social media and email list contacts of the research team. In keeping with the approach, descriptive statistics of survey data and thematic analysis of qualitative interview and open-ended questions in survey data were combined. RESULTS: For most respondents who received a prescription during lockdown, this was sent directly to the pharmacy. Most people picked up their medication from the pharmacy; home delivery of medication was rare (4%). Survey and interview respondents wanted e-prescribing to continue post-lockdown and described where things worked well and where they encountered delays in the process of acquiring prescription medication. CONCLUSIONS: E-prescribing has the potential to improve access to prescription medication and is convenient for patients. The increase in e-prescribing during lockdown highlighted how the system could be improved, through better feedback about errors, more consistency across practices and pharmacies, more proactive communication with patients, and equitable prescribing costs.

RESUMO

BACKGROUND: Medicines are central to healthcare in aging populations with chronic multi-morbidity. Their safe and effective use relies on a large and constantly increasing knowledge base. Despite the current era of unprecedented access to information, there is evidence that unmet information needs remain an issue in clinical practice. Unmet medicines information needs may contribute to sub-optimal use of medicines and patient harm. Little is known about medicines information needs in the primary care setting. The aim of this study was to investigate the nature of medicines information needs in routine general practice and understand the challenges and influences on the information-seeking behaviour of general practitioners. METHODS: A mixed methods study involving 18 New Zealand general practitioner participants was undertaken. Quantitative data were collected to characterize the medicines information needs arising during 642 consultations conducted by the participants. Qualitative data regarding participant views on their medicines information needs, resources used, challenges to meeting the needs and potential solutions were collected by semi-structured interview. Integration occurred by comparison of results from each method. RESULTS: Of 642 consultations, 11% (n = 73/642) featured at least one medicines information need. The needs spanned 14 different categories with dosing the most frequent (26%) followed by side effects (15%) and drug interactions (14%). Two main themes describing the nature of general practitioners' medicines information needs were identified from the qualitative data: a 'common core' related to medicine dose, side effects and interactions and a 'perplexing periphery'. Challenges in the perplexing periphery were the variation in information needs, complexity, 'known unknowns' and 'unknown unknowns'. Key factors affecting general practitioners' strategies for meeting medicines information needs were trust in a resource, presence of the patient, how the information was presented, scarcity of time, awareness of the existence of a resource, and its accessibility. CONCLUSIONS: General practitioners face challenges in meeting wide-ranging medicines information needs in patients with increasingly complex care needs. Recognising the challenges and factors that influence resource use in practice can inform optimisation of medicines information support resources. Resources for general practitioners must take into account the complexity and time constraints of real-world practice. An individually responsive approach involving greater collaboration with pharmacists and specialist medicines information support services may provide a potential solution.

RESUMO

OBJECTIVES: Mental illness is an important public health issue internationally. As people with mild-to-moderate illness are usually cared for in primary health care, pharmacists are well placed to play an important role. The study objectives were to explore community pharmacists' perceptions of their role in primary mental health care and the barriers and facilitators to the provision of care in New Zealand. METHODS: Fifteen face-to-face, semi-structured interviews were undertaken with practising pharmacists nationally. Interviews were audio-taped and transcribed verbatim. Data were analysed iteratively using an inductive thematic approach. KEY FINDINGS: Support offered to patients with mild-to-moderate mental illness ranged from solely dispensing to providing more holistic, patient-centred care. Three key themes were identified with the potential to influence whether participants were willing and able to support patients. These were pharmacists' beliefs about their role in primary mental health care, their perception of patients' needs and the environmental context in which they were practising. The connection to the local community and the philosophy of the business owner were contexts that strongly influenced the support provided. CONCLUSIONS: Community pharmacists have a valuable contribution and role to play in supporting primary mental health care extending well beyond medicines supply and the provision of advice about medicines. Advocacy roles including health system navigation and much broader social support are also possible. The philosophy of the business owner and the actual impact this has on a pharmacist's practice and the time available to support patients is likely to be influential.

RESUMO

The design and assembly of peptide-based materials has advanced considerably, leading to a variety of fibrous, sheet, and nanoparticle structures. A remaining challenge is to account for and control different possible supramolecular outcomes accessible to the same or similar peptide building blocks. Here a de novo peptide system is presented that forms nanoparticles or sheets depending on the strategic placement of a "disulfide pin" between two elements of secondary structure that drive self-assembly. Specifically, homodimerizing and homotrimerizing de novo coiled-coil α-helices are joined with a flexible linker to generate a series of linear peptides. The helices are pinned back-to-back, constraining them as hairpins by a disulfide bond placed either proximal or distal to the linker. Computational modeling indicates, and advanced microscopy shows, that the proximally pinned hairpins self-assemble into nanoparticles, whereas the distally pinned constructs form sheets. These peptides can be made synthetically or recombinantly to allow both chemical modifications and the introduction of whole protein cargoes as required.

RESUMO

COVID-19 is caused by a novel coronavirus called severe acute respiratory syndrome-coronavirus 2 (SARS-CoV-2). Virus cell entry is mediated through a protein-protein interaction (PPI) between the SARS-CoV-2 spike protein and angiotensin-converting enzyme 2 (ACE2). A series of stapled peptide ACE2 peptidomimetics based on the ACE2 interaction motif were designed to bind the coronavirus S-protein RBD and inhibit binding to the human ACE2 receptor. The peptidomimetics were assessed for antiviral activity in an array of assays including a neutralization pseudovirus assay, immunofluorescence (IF) assay and in-vitro fluorescence polarization (FP) assay. However, none of the peptidomimetics showed activity in these assays, suggesting that an enhanced binding interface is required to outcompete ACE2 for S-protein RBD binding and prevent virus internalization.

RESUMO

INTRODUCTION People receiving opioid substitution treatment are a vulnerable population who experience significant health inequities and stigma, but have regular interactions with community pharmacists. Many pharmacists now work collaboratively with other health providers to ensure effective and safe use of medicines, as well as being involved in the prevention and management of chronic health conditions. AIM To explore the role of New Zealand community pharmacists in the provision of opioid substitution treatment and how they perceive their role as part of the wider opioid substitution treatment team. METHODS Semi-structured video interviews with a purposive sample of 13 diverse pharmacists explored their current practices in providing opioid substitution treatment, and their perceived role in the treatment team. Interviews were audio-recorded and transcribed verbatim. Data were coded and analysed using an inductive thematic approach. RESULTS This study found that pharmacists are providing accessible support to a population with known barriers to accessing health care. However, participants also identified challenges with communication and a perceived lack of understanding of the pharmacist role as barriers to collaboration with the wider opioid substitution treatment team. DISCUSSION Collaboration within health-care teams has been shown to improve health outcomes, and pharmacists are well placed to provide health-care services as well as offer valuable insight into clients' mental and physical wellbeing. Improved communication channels that facilitate information sharing, as well as the opioid substitution treatment team's recognition of a pharmacist's role, may facilitate collaboration and, in turn, improve the quality of health care provided to this vulnerable population.

RESUMO

BACKGROUND: Extramammary Paget disease (EMPD) is a rare malignancy with unclear pathophysiology that occurs predominantly on apocrine rich skin. Surgery is the treatment of choice; however, procedures tend to be extensive and associated with a high rate of recurrence. OBJECTIVE: To review the current literature on EMPD regarding epidemiology, pathogenesis, clinical presentation, histology, diagnostic work-up, treatment, and prognosis. MATERIALS AND METHODS: Literature review using PubMed search for articles related to EMPD. RESULTS: Extramammary Paget disease classically presents as a slowly growing red plaque, which often mimics an inflammatory condition leading to significant delay in diagnosis. Diagnosis requires histopathologic examination and is often supported by immunohistochemical analysis. Once a diagnosis of EMPD is made, the patient must be risk-stratified and evaluated for an underlying malignancy. CONCLUSION: Standard of treatment is surgery, with data suggesting that Mohs micrographic surgery may have superior clinical outcomes and lower recurrence rates. Alternatives such as photodynamic therapy and topicals have been explored and may be appropriate in certain situations. Patients with EMPD generally have a good prognosis with a 5-year overall survival rate of 75% to 95%.

RESUMO

OBJECTIVE: The present parallel randomised control trial evaluated the feasibility of a nurse-led psycho-educational intervention aimed at improving the self-management of prostate cancer survivors. METHODS: We identified 305 eligible patients from a district general hospital, diagnosed 9-48 months previously, who completed radical treatment, or were monitored clinically (ineligible for treatment). Ninety-five patients were recruited by blinded selection and randomised to Intervention (N = 48) and Control (N = 47) groups. Participant allocation was revealed to patients and researchers after recruitment was completed. For 36 weeks, participants received augmented usual care (Control) or augmented usual care and additional nurse support (Intervention) provided in two community hospitals and a university clinic, or by telephone. RESULTS: Data from 91 participants (Intervention, N = 45; Control, N = 46) were analysed. All feasibility metrics met predefined targets: recruitment rate (31.15%; 95% CI: 25.95%-36.35%), attrition rate (9.47%; 95% CI: 3.58%-15.36%) and outcome measures completion rates (77%-92%). Forty-five patients received the intervention, with no adverse events. The Extended Prostate Cancer Index Composite can inform the minimum sample size for a future effectiveness trial. The net intervention cost was £317 per patient. CONCLUSIONS: The results supported the feasibility and acceptability of the intervention, suggesting that it should be evaluated in a fully powered trial to assess its effectiveness and cost-effectiveness.
