Interprofessional learning in practice-based settings: AMEE Guide No. 169.

The provision of optimum health care services requires collaboration of health care professionals in integrated interprofessional (IP) teams. This guide addresses the practical aspects of establishing and delivering pre-licensure IP programs to prepare graduates of health professional programs to work in teams and wider collaboration, and consequently enhance the quality of health care. The main updated IP frameworks are presented to highlight commonalities that represent the essential competencies and outcomes of programs implementing interprofessional education (IPE). We discuss how these may be adapted to the local context, and present examples of models of implementation to guide the initial steps of establishing similar programs. Examples of pre-licensure IP practice-based learning, such as community-based, simulation-based, student-run and led clinics, and interprofessional training wards, and post-licensure interprofessional learning (IPL), are described. We consider assessment of IPL along the continuum of learning IP. This guide also emphasises the need to tailor faculty development programs for local contexts and consider factors affecting sustainability such as funding and accreditation. We finish with the governance of IP programs and how global IP networks may support interprofessional practice-based learning from development to delivery.

Randomized Placebo-Controlled Trial of 60-Day Percutaneous Peripheral Nerve Stimulation Treatment Indicates Relief of Persistent Postoperative Pain, and Improved Function After Knee Replacement.

OBJECTIVES: Total knee arthroplasty (TKA) is an effective surgery for end-stage knee osteoarthritis, but chronic postoperative pain and reduced function affect up to 20% of patients who undergo such surgery. There are limited treatment options, but percutaneous peripheral nerve stimulation (PNS) is a promising nonopioid treatment option for chronic, persistent postoperative pain. The objective of the present study was to evaluate the effect of a 60-day percutaneous PNS treatment in a multicenter, randomized, double-blind, placebo-controlled trial for treating persistent postoperative pain after TKA. MATERIALS AND METHODS: Patients with postoperative pain after knee replacement were screened for this postmarket, institutional review board-approved, prospectively registered (NCT04341948) trial. Subjects were randomized to receive either active PNS or placebo (sham) stimulation. Subjects and a designated evaluator were blinded to group assignments. Subjects in both groups underwent ultrasound-guided placement of percutaneous fine-wire coiled leads targeting the femoral and sciatic nerves on the leg with postoperative pain. Leads were indwelling for eight weeks, and the primary efficacy outcome compared the proportion of subjects in each group reporting ≥50% reduction in average pain relative to baseline during weeks five to eight. Functional outcomes (6-minute walk test; 6MWT and Western Ontario and McMaster Universities Osteoarthritis Index) and quality of life (Patient Global Impression of Change) also were evaluated at end of treatment (EOT). RESULTS: A greater proportion of subjects in the PNS groups (60%; 12/20) than in the placebo (sham) group (24%; 5/21) responded with ≥50% pain relief relative to baseline (p = 0.028) during the primary endpoint (weeks 5-8). Subjects in the PNS group also walked a significantly greater distance at EOT than did those in the placebo (sham) group (6MWT; +47% vs -9% change from baseline; p = 0.048, n = 18 vs n = 20 completed the test, respectively). Prospective follow-up to 12 months is ongoing. CONCLUSIONS: This study provides evidence that percutaneous PNS decreases persistent pain, which leads to improved functional outcomes after TKA at EOT.

Tarnished jewellery and skin - a subtle external marker indicating exposure to hydrogen sulfide.

A 39-year-old woman was found lying in the rear of a car at her home address. A smell of rotten eggs was noted and bottles of brick, tile and paver cleaner and lime sulfur were found in the rear of the vehicle. Suicide notes were found in the house. At autopsy there was no evidence of significant trauma with black tarnishing of a silver-coloured ring and a silver-coloured necklace noted with staining of the underlying skin, in keeping with a chemical reaction between hydrogen sulfide and silver. Internally the most significant finding was unusual greenish discolouration of the gray matter of the external and cut surfaces of the cerebral hemispheres, cerebellum and brain stem. No other organs had this discoloration. Death was attributed to hydrogen sulfide poisoning. Skin discoloration from silver jewellery may represent a subtle external marker for lethal or non-lethal hydrogen sulfide exposure.

Acanthosis nigricans - a potentially useful clue to the presence of significant occult disease at autopsy.

A 19-year-old male was found dead in his apartment. At autopsy he was morbidly obese (Body mass index; BMI - 40.5) with multiple areas of velvety pigmented thickening of the skin in folds around the neck, in the axillae, in the inframammary regions, over the anterior waistline and groin regions and over the dorsal aspects of the feet. These had the typical appearance of acanthosis nigricans. Internal examination revealed aspiration of gastric contents into the airways. Vitreous humour biochemistry showed markedly elevated levels of both glucose (62.9 mmol/L) and ß-hydroxybutyrate (13.54 mmol/L). Death was, therefore, due to aspiration pneumonia complicating diabetic ketoacidosis on a background of morbid obesity. The initial indicator of underlying diabetes, in conjunction with obesity had been acanthosis nigricans.

Cardiac tamponade - a rare cause of sudden death in autoimmune polyglandular syndrome.

A 27-year-old male died suddenly due to cardiac tamponade arising from pericarditis complicating autoimmune polyglandular syndrome (APS) type 2. He had a history of primary Addison disease and autoimmune hypothyroidism which were corroborated at autopsy. In addition a florid fibrinous pericarditis was associated with 287 g of turbid fluid in the pericardial sac. Although pericarditis with tamponade is a potential complication of APS, it has rarely if ever, been reported as a cause of sudden death. Lethal mechanisms may involve both compressive and restrictive effects.

Network model of nociceptive processing in the superficial spinal dorsal horn reveals mechanisms of hyperalgesia, allodynia, and spinal cord stimulation.

The spinal dorsal horn (DH) processes sensory information and plays a key role in transmitting nociception to supraspinal centers. Loss of DH inhibition during neuropathic pain unmasks a pathway from nonnociceptive Aß-afferent inputs to superficial dorsal horn (SDH) nociceptive-specific (NS) projection neurons, and this change may contribute to hyperalgesia and allodynia. We developed and validated a computational model of SDH neuronal circuitry that links nonnociceptive Aß-afferent inputs in lamina II/III to a NS projection neuron in lamina I via a network of excitatory interneurons. The excitatory pathway and the NS projection neuron were in turn gated by inhibitory interneurons with connections based on prior patch-clamp recordings. Changing synaptic weights in the computational model to replicate neuropathic pain states unmasked a low-threshold excitatory pathway to NS neurons similar to experimental recordings. Spinal cord stimulation (SCS) is an effective therapy for neuropathic pain, and accumulating experimental evidence indicates that NS neurons in the SDH also respond to SCS. Accounting for these responses may inform therapeutic improvements, and we quantified responses to SCS in the SDH network model and examined the role of different modes of inhibitory control in modulating NS neuron responses to SCS. We combined the SDH network model with a previously published model of the deep dorsal horn (DDH) and identified optimal stimulation frequencies across different neuropathic pain conditions. Finally, we found that SCS-generated inhibition did not completely suppress model NS activity during simulated pinch inputs, providing an explanation of why SCS does not eliminate acute pain.NEW & NOTEWORTHY Chronic pain is a severe public health problem that reduces the quality of life for those affected and exacts an enormous socio-economic burden worldwide. Spinal cord stimulation (SCS) is an effective treatment for chronic pain, but SCS efficacy has not significantly improved over time, in part because the mechanisms of action remain unclear. Most preclinical studies investigating pain and SCS mechanisms have focused on the responses of deep dorsal horn (DDH) neurons, but neural networks in the superficial dorsal horn (SDH) are also important for processing nociceptive information. This work synthesizes heterogeneous experimental recordings from the SDH into a computational model that replicates experimental responses and that can be used to quantify neuronal responses to SCS under neuropathic pain conditions.

The development of interprofessional education and collaborative practice in Latin America and the Caribbean: preliminary observations.

The Pan-American Health Organization (PAHO) and World Health Organization have encouraged countries across Latin America and the Caribbean (LAC) to incorporate interprofessional education and collaborative practice (IPECP) into policies on the health workforce, and support policymakers in expanding its use. PAHO recommend countries to promote the development of interprofessional teams in integrated health services networks using IPECP. The creation of the Regional Network for Interprofessional Education in the Americas, the mobilization of a series of IPECP regional meetings, and the development of national IPECP action plans are the most promising results achieved thus far. This report describes the process of implementing IPECP in LAC countries as an innovative initiative in interprofessional health policy.

The applicability of interprofessional education for collaborative people-centered practice and care to health plans and workforce issues: A thematic global case review.

Background: This article focuses on a growing, global recognition of the importance of the field of interprofessional education for person-centered collaborative practice (IPECP) expressed through high-level policy and accreditation decisions/actions taking place in 5 countries. Policy decisions are used to motivate strategies related to IPECP that align with national health plans, and workforce issues. Methods: Using a collective of representative stories from around the globe, a grouping of case studies were developed to illustrate different approaches and challenges to IPECP implementation. Results: Institutions from countries of various income levels face many similar challenges in the execution, delivery, and sustainability of IPECP. All programs face issues of financing, of preparing faculty, of developing and organizing curricula, and of bridging between campus and community. Discussion: Policies are being developed that promote a global approach to the inclusion of IPECP in the accreditation and regulation of postsecondary institutions and health service organizations, in keeping with WHO National Health Workforce Accounts. Policies developed promote and demonstrate the benefits of IPECP through remote emergency learning methods. The policies also build national systems for IPECP as an integral part of continuing professional development and lifelong learning. The organization of interprofessional research programs and the increasing publication of their results of such programs will lead to a clearer understanding of the efficacy of the field of IPECP. To ensure sustainability, stakeholders and policymakers should continue to foster policies that facilitate IPECP.

Accreditation as a driver of interprofessional education: the Canadian experience.

BACKGROUND: The purpose of this study was to (1) explore evidence provided by Canadian health and social care (HASC) academic programs in meeting their profession-specific interprofessional education (IPE)-relevant accreditation standards; (2) share successes, exemplars, and challenges experienced by HASC academic programs in meeting their IPE-relevant accreditation standards; and (3) articulate the impacts of IPE-relevant accreditation standards on enabling interprofessional learning to the global HASC academic community. METHODS: Profession-specific (bilingual, if requested) surveys were developed and emailed to the Deans/Academic Program Directors of eligible academic programs with a request to forward to the individual who oversees IPE accreditation. Responses were collated collectively and by profession. Open-ended responses associated with our first objective were deductively categorized to align with the five Accreditation of Interprofessional Health Education (AIPHE) standards domains. Responses to our additional questions associated with our second and third objectives were inductively categorized into themes. RESULTS/DISCUSSION: Of the 270 HASC academic programs surveyed, 30% (n = 24) partially or completely responded to our questions. Of the 106 IPE-relevant standards where evidence was provided, 62% (n = 66) focused on the Educational Program, 88% of which (n = 58) were either met or partially met, and 47% (n = 31) of which focused on practice-based IPE. Respondents cited various exemplars and challenges in meeting IPE-relevant standards. CONCLUSIONS: The overall sentiment was that IPE accreditation was a significant driver of the IPE curriculum and its continuous improvement. The array of exemplars described in this paper may be of relevance in advancing IPE implementation and accreditation across Canada and perhaps, more importantly, in countries where these processes are yet emerging.

Interprofessional educators' competencies, assessment, and training - IPEcat: protocol of a global consensus study.

Contemporary practice in interprofessional education (IPE) has evolved predominantly focusing on the competencies for interprofessional collaboration (IPC) that learners must acquire. Competencies that educators need to successfully deliver IPC have been overlooked. This lack of attention is further confounded by a field replete with inconsistent terminology and standards and no global consensus on the core competencies needed for IPE facilitation. There are no globally accepted tools to assess interprofessional educators' competencies nor are there established training programmes that might be used as the basis for a collective global approach to these issues. The International Working Group for Interprofessional Educators Competencies, Assessment, and Training (IWG_IPEcat) seeks to address this gap using a sequential mixed-method approach, to deliver globally developed, empirically derived tools to foster IPE educator competencies. This article presents the protocol of the research project.

Patterned lividity - the 'underwear sign'.

Lividity or livor mortis occurs when blood settles in dependent areas after death due to gravitational effects. Patterned lividity may result from a body lying against a variety of surfaces. Two case are presented where lividity was prevented by tight fitting elastic underwear except in areas where letters from the manufacturers' names had elevated the material, thus permitting capillaries in the underlying skin to fill. This type of patterned lividity may act as a useful record of the type of clothing being worn at the time of death and in the hours following.

Laryngeal oncocytic cystadenoma and sudden death.

An 86-year-old woman with Alzheimer disease collapsed in her nursing home and was not able to be resuscitated. At autopsy, the major findings were in the larynx where a pedunculated oncocytic cystadenoma had occluded the glottis. Oncocytic cysts or cystadenomas of the larynx are rare histologically benign lesions that account for only 0.1-1% of laryngeal lesions. While the usual presentation is of a sensation of a mass in the throat, hoarseness, or stridor, very occasionally, there may be acute airway compromise and sudden death. Oncocytic cystadenoma should, therefore, be included in the differential diagnosis of potentially lethal obstructive laryngeal lesions.

Camel-Related Deaths-A Forensic Overview.

ABSTRACT: Camels are ungulates of the genus Camelus and have been used for centuries in parts of Asia and Africa for transport and sustenance. Handling of camels is not without its dangers, and 4 cases from South Australia are reported with a review of lethal camel-related issues. Case 1 is a 56-year-old man who died of multiple blunt force injuries after he had attempted to move a 7-year-old female dromedary (Camelus dromedarius). Case 2 is a 65-year-old woman who was crushed by 1 or more camels that she had been training. Case 3 is a 1-year-old girl who died of blunt craniocerebral trauma after the car in which she was traveling rolled when the driver swerved to avoid a herd of camels that had strayed onto the road. Case 4 is a 66-year-old woman who died of ischemic and hypertensive cardiac disease exacerbated by physical activity while rounding up camels. Deaths associated with camels involve kicking, stomping, kneeling or sitting on a victim, or biting and shaking and throwing. Lethal mechanisms include hemorrhage from vascular injuries and internal organ disruption, crush asphyxia, and blunt craniospinal injuries. Death may also follow falls from camels or vehicle collisions. Camels also carry a wide range of zoonotic diseases, the most significant of which is Middle Eastern respiratory syndrome. Handling of camels may also exacerbate underlying organic illnesses such as cardiac disease. Those working with camels should be aware that the size, strength, and temperament of these animals may make them dangerous and that they also carry potentially lethal zoonotic diseases.

Actinomyces in Forensic Practice.

ABSTRACT: A 19-year-old woman in septic shock with recent computed tomography findings of a loculated hepatic abscess was transferred to an intensive care unit where she went into asystolic cardiac arrest. After resuscitation, surgical exploration revealed a purulent pericardial effusion with tamponade and a liver abscess. Microbiological analyses from both sites were negative. Shortly after surgical exploration, she developed multiorgan failure and died. At autopsy, pus was observed both within the pericardial cavity and around the left lobe of the liver. Green "sulfur granules" suggestive of infection with Actinomyces spp. were able to be extruded from the liver during the postmortem examination and cultures returned positive for Actinomyces israelii. This case is a rare example of primary hepatic actinomycosis infection that resulted in the death of a young woman. Nonspecific clinical manifestations may delay diagnosis; however, the finding of "sulfur granules" in areas of abscess formation at autopsy should be taken as an indication of possible underlying Actinomyces infection.

Unexpected Death Associated With Clostridial Sepsis.

ABSTRACT: An 85-year-old woman with a history of breast carcinoma presented to hospital after gradual onset of abdominal pain with hypotension, jaundice, and massive intravascular hemolysis. This was caused by Clostridium perfringens septicemia originating from a liver abscess. Clostridium perfringens septicemia is a rare infection that has a high mortality rate, given that it is frequently unable to be diagnosed until postmortem examination. The source of the pathogen is usually intra-abdominal. Hepatic abscesses, although an uncommon source of primary clostridial infection, should be considered in such cases.

Ludwig angina and sudden death.

A 27-year-old man presented to hospital with neck swelling and difficulty breathing following a recent tooth extraction. He underwent uncomplicated surgical drainage of the submandibular region after which he became acutely short of breath and collapsed and was not able to be resuscitated. At autopsy the major findings were swelling of the neck due to diffuse cellulitis with edema and neutrophil infiltrates within connective tissue and marked submucosal edema of the epiglottis, glottic inlet and tonsils sufficient to cause airway obstruction. Cultures from the site of surgical intervention showed a mixed growth of Gram positive and negative bacilli and Gram positive cocci. Death was due to airway obstruction resulting from marked submucosal edema of the glottic inlet associated with submandibular cellulitis (Ludwig's angina) following extraction of a right lower first molar tooth. Lethal Lugwig angina, although rare in current forensic practice, may still present as a cause of acute upper airway occlusion and must be considered in the differential diagnosis of significant upper airway compromise.

Seat belt asphyxia as a lethal mechanism in motor vehicle crashes.

A 28-year-old driver was found dead in his car after impact with a truck. At the scene he was seated in the driver's seat partially hanging out of the vehicle with the sash component of the seatbelt tightly pressed into his neck. At autopsy there was evidence of neck compression with bilateral conjunctival petechial hemorrhages and fracture of the right superior horn of the thyroid cartilage. Limb fractures and internal injuries were not associated with significant hemorrhage. There was no evidence of brain trauma. Death was, therefore due to neck compression from the seatbelt demonstrating an additional rare lethal mechanism that may be encountered in vehicle crashes. External bruises and abrasions may not be present around the neck due to padding from clothing, however conjunctival petechiae and neck injuries are supportive of the diagnosis.

Signet-ring cell appearance of atrophic fat cells.

Cells with 'signet-ring' appearance were found at post-mortem examination of a man with a history of chronic illness, weight loss and multiple regions of 'bowel thickening' during life. Due to the decedent's history, the finding raised the possibility of disseminated signet-ring adenocarcinoma. However, the vacuoles did not stain for mucin and the cells did not stain for keratin. The cells did stain for calretinin and so a diagnosis of signet ring mesothelioma was considered. However, it was suggested that the cells with a cytoplasmic vacuole displacing the nucleus to one side producing the signet-ring appearance were instead atrophic fat cells. This was subsequently proven by Oil Red O staining.

Interprofessional simulation education to enhance teamwork and communication skills among medical and nursing undergraduates using the TeamSTEPPS® framework.

BACKGROUND: Learning in silos during the undergraduate years results in ineffective collaborative practice leading to adverse events. Simulation training using the Team Strategies and Tools to Enhance Performance and Patient Safety (TeamSTEPPS)® framework has been shown to be effective in enhancing teamwork skills among healthcare professionals. This study aims to evaluate an interprofessional simulation education (IPSE) module for undergraduate medical and nursing students on teamwork and communication skills using the TeamSTEPPS® framework. METHODS: An IPSE module was developed by an interprofessional team of faculty. A convenient sample of medical and nursing undergraduate interns participated in trauma simulation scenarios before and after a didactic session on interprofessional education (IPE) and TeamSTEPPS® 2.0. The pre-post performance was assessed by faculty and pre-post self-assessment of the IPSE training and interprofessional education collaborative (IPEC) competencies by the participants. Quantitative data were analysed using a paired t-test of the mean scores and analysis of variance. The themes that emerged from audio recordings of the debriefing, and written reflections of the participants, yielded data for qualitative thematic analysis. RESULTS: The scores of team performance, self-assessment of IPSE training, and IPEC competencies revealed statistically significant values. Themes that emerged included the need for IPSE in the curriculum, impact of structured tools for communication on patient safety, and awareness of the roles and responsibilities in interprofessional teamwork. A survey conducted two weeks after completion of the module showed positive feelings among participants about interprofessional collaboration. CONCLUSION: The study specifically assessed the effectiveness of an IPSE module based on TeamSTEPPS® guidelines in improving communication and teamwork skills among medical and nursing undergraduates.

The COVID-19 crisis silver lining: interprofessional education to guide future innovation.

Globally, the advent and rapid spread of the COVID-19 virus has created significant disruption to health professions education and practice, and consequently interprofessional education, leading to a model of learning and practicing where much is unknown. Key questions for this ongoing evolution emerge for the global context leading to reflections on future directions for the interprofessional education field and its role in shaping future practice models. Health professions programs around the world have made a dramatic shift to virtual learning platforms in response to closures of academic institutions and restrictions imposed on learners accessing practice settings. Telemedicine, slow to become established in many countries to date, has also revolutionized practice in the current environment. Within the state of disruption and rapid change is the awareness of a silver lining that provides an opportunity for future growth. Key topics explored in this commentary include reflection on the application of existing competency frameworks, consideration of typology of team structures, reconsideration of theoretical underpinnings, revisiting of core dimensions of education, adaptation of interprofessional education activities, and the role in the future pandemic planning. As an international community of educators and researchers, the authors consider current observations relevant to interprofessional education and practice contexts and suggest a response from scholarship voices across the globe. The current pandemic offers a unique opportunity for educators, practitioners, and researchers to retain what has served interprofessional education and practice well in the past, break from what has not worked as well, and begin to imagine the new.
