Integrating interprofessional electronic medical record teaching in preregistration healthcare degrees: A case study.

BACKGROUND: Electronic medical record (EMR) adoption across healthcare necessitates a purposeful curriculum design to prepare graduates for the delivery of safe and effective patient care in digitally-enabled environments. OBJECTIVE: To describe the design and development of an Interprofessional Electronic Medical Record (iEMR) subject that introduces healthcare students to its utility in clinical settings. METHODS: A six-stage design-based educational research framework (Focus, Formulation, Contextualisation, Definition, Implementation, Evaluation) was used to instigate the iEMR design and development in nursing and five allied health graduate entry to practice (preregistration) degrees at an Australian university. RESULTS: In the Focus process, the concept and interdisciplinary partnerships were developed. The Formulation process secured grant support for subject design and development, including a rapid literature review to accommodate various course and curriculum structures. Discipline-specific subject themes were created through the Contextualisation process. During the Definition process, learning objectives and content resources were built. The Implementation process describes the pilot implementation in the nursing program, where assessment tasks were refined, and interdisciplinary clinical case studies originated. DISCUSSION: The design and development of an iEMR subject is underpinned by internal support for educational innovation and in alignment with digital health strategies in employer organisations. Identified barriers include faculty-level changes in strategic support for teaching innovation, managerial expectations of workload, the scope of work required by academics and learning designers, and the gap between the technology platform required to support online learning and the infrastructure needed to support simulated EMR use. A key discovery was the difficulty of finding EMR software, whether designed for teaching purposes or for clinical use, that could be adapted to meet the needs of this project. CONCLUSION: The lessons learned are relevant to educators and learning designers attempting a similar process. Issues remain surrounding the sustainability of the iEMR subject and maintaining academic responsibility for ongoing curriculum management.

Role of predisposition, injury, response and organ failure in the prognosis of patients with acute-on-chronic liver failure: a prospective cohort study.

INTRODUCTION: Acute deterioration of cirrhosis is associated with high mortality rates particularly in the patients who develop organ failure (OF), a condition that is referred to as acute-on-chronic liver failure (ACLF), which is currently not completely defined. This study aimed to determine the role of predisposing factors, the nature of the precipitating illness and inflammatory response in the progression to OF according to the PIRO (predisposition, injury, response, organ failure) concept to define the risk of in-hospital mortality. METHODS: A total of 477 patients admitted with acute deterioration of cirrhosis following a defined precipitant over a 5.5-year period were prospectively studied. Baseline clinical, demographic and biochemical data were recorded for all patients and extended serial data from the group that progressed to OF were analysed to define the role of PIRO in determining in-hospital mortality. RESULTS: One hundred and fifty-nine (33%) patients developed OF, of whom 93 patients died (58%) compared with 25/318 (8%) deaths in the non-OF group (P < 0.0001). Progression to OF was associated with more severe underlying liver disease and inflammation. In the OF group, previous hospitalisation (P of PIRO); severity of inflammation and lack of its resolution (R of PIRO); and severity of organ failure (O of PIRO) were associated with significantly greater risk of death. In the patients who recovered from OF, mortality at three years was almost universal. CONCLUSIONS: The results of this prospective study shows that the occurrence of OF alters the natural history of cirrhosis. A classification based on the PIRO concept may allow categorization of patients into distinct pathophysiologic and prognostic groups and allow a multidimensional definition of ACLF.

Alterations in the functional capacity of albumin in patients with decompensated cirrhosis is associated with increased mortality.

UNLABELLED: Albumin concentration is diminished in patients with liver failure. Albumin infusion improves survival of cirrhotic patients with spontaneous bacterial peritonitis, and it is hypothesized that this may be due in part to its detoxifying capabilities. The aim of this study was to perform detailed quantitative and qualitative assessment of albumin function in patients with cirrhosis. Healthy controls and patients with acute deterioration of cirrhosis requiring hospital admission (n = 34) were included. Albumin function was assessed using affinity of the fatty acid binding sites using a spin label (16 doxyl-stearate) titration and electron paramagnetic resonance spectroscopy and ischemia-modified albumin (IMA) was measured. Twenty-two patients developed acute-on-chronic liver failure. Twelve were treated with the Molecular Adsorbents Recirculating System (MARS) and 10 with standard medical therapy. For each parameter measured, the patients' albumin had reduced functional ability, which worsened with disease severity. Fifteen patients died, and IMA, expressed as an albumin ratio (IMAR), was significantly higher in nonsurvivors compared with survivors (P < 0.001; area under the receiver operating curve = 0.8). No change in the patients' albumin function was observed following MARS therapy. A significant negative correlation between IMAR and the fatty acid binding coefficients for sites 1 and 2 (P < 0.001 for both) was observed, indicating possible sites of association on the protein. CONCLUSION: The results of this study suggests marked dysfunction of albumin function in advanced cirrhosis and provide further evidence for damage to the circulating albumin, which is not reversed by MARS therapy. IMAR correlates with disease severity and may have prognostic use in acute-on-chronic liver failure.

Albumin dialysis reduces portal pressure acutely in patients with severe alcoholic hepatitis.

BACKGROUND/AIMS: In patients with alcoholic hepatitis (AH), inflammation contributes to the severity of portal hypertension. This study evaluates the acute effects of albumin dialysis, using the Molecular Adsorbents Recirculating System (MARS), on portal pressure in AH. METHODS: Eleven patients with AH and portal hypertension were treated with MARS (n=8) or haemofiltration (n=3). All patients had associated organ failure manifested by hepatic encephalopathy (Grade 2 or more) or renal failure. Hepatic venous pressure gradient (HVPG) was measured before, during and after the treatment session. RESULTS: A rapid significant reduction of HVPG was observed by 6 h (falling by > or =20% in 7/8 patients, reaching 12 mmHg in 6/8), which was sustained up to 18 h after stopping dialysis. Similar rapid sustained improvements of systemic haemodynamics were also observed. No changes occurred in three patients receiving haemofiltration alone. CONCLUSIONS: Albumin dialysis produces clinically significant, acute reduction in portal pressure but the mechanism by which this effect is achieved is not clear. Our results suggest that MARS may be a useful adjunct in management of portal hypertension, particularly in patients with severe AH with associated organ failure.

Pathophysiological effects of albumin dialysis in acute-on-chronic liver failure: a randomized controlled study.

The pathophysiological basis of acute-on-chronic liver failure (ACLF) is unclear but systemic inflammatory response is thought to be important. In patients with ACLF, the molecular adsorbents recirculating system (MARS) improves individual organ function, but the effect of MARS on the proposed mediators of systemic inflammatory response is unclear. The present study was designed to determine the effect of MARS on the cytokine profile, oxidative stress, nitric oxide, and ammonia. A total of 18 patients with alcohol-related ACLF due to inflammation-related precipitants were randomized to receive standard medical therapy (SMT) alone, or with MARS therapy over 7 days. Plasma cytokines, malondialdehyde (MDA), free radical production, nitrate / nitrite (NOx), and ammonia were measured. Encephalopathy improved significantly with MARS (P < .01), but not with SMT. Mean arterial pressure and renal function remained unchanged. No significant change of plasma cytokines and ammonia levels were observed in either group. Plasma MDA levels did not change either. There was a fall in NOx (P < .05) with MARS, but not with SMT. In conclusion, in inflammation-related ACLF patients, albumin dialysis using MARS results in improvement of encephalopathy, independent of changes of ammonia or cytokines, without improving blood pressure or renal function. These results should temper the liberal use of MARS until further data is available.
