Frequency and potential causes of non-beneficial Code Blue activations at a metropolitan teaching hospital.

BACKGROUND: Code Blue activations in patients who are not for resuscitation (NFR) may be regarded as non-beneficial and may cause harm to patients, relatives and hospital staff. AIMS: To estimate the prevalence of non-beneficial Code Blue calls in a metropolitan teaching hospital and identify modifiable factors that could be utilised to reduce these events. METHODS: The study consisted of two parts: (i) a retrospective analysis of all Code Blue activations over a 12-month period using prospectively collected data. Non-beneficial activations were defined as calls made in patients with a NFR order in either the current or any previous hospital admissions and (ii) an anonymous voluntary survey of staff who were present at a Code Blue activation. RESULTS: There were 186 Code Blue activations over the study period, with 48 (25.8%) defined as non-beneficial. Such patients had more comorbidities, previous hospitalisations and greater levels of frailty. Most non-beneficial calls occurred on general wards and more than three-quarters of patients had been reviewed by a consultant prior to the call. The survey determined that despite ward staff having a considerable degree of resuscitation experience, there were deficiencies in understanding of Code Blue criteria, the resuscitation status of patients under their care and the interpretation of goals of care. CONCLUSIONS: Over a quarter of Code Blue calls were deemed non-beneficial. Improving the visibility of NFR status and staff understanding of patient goals of care are needed, along with timely, proactive documentation of NFR status by experienced clinicians.

Non-beneficial resuscitation during inhospital cardiac arrests in a metropolitan teaching hospital.

BACKGROUND: There is increasing recognition that a proportion of hospitalised patients receive non-beneficial resuscitation, with the potential to cause harm. AIM: To describe the prevalence of non-beneficial resuscitation attempts in hospitalised patients and identify interventions that could be used to reduce these events. METHODS: A retrospective analysis was conducted of all adult inhospital cardiac arrests (IHCA) receiving cardiopulmonary resuscitation (CPR) in a teaching hospital over 9 years. Demographics and arrest characteristics were obtained from a prospectively collected database. Non-beneficial CPR was defined as CPR being administered to patients who had a current not-for-resuscitation (NFR) order in place or who had a NFR order enacted on a previous hospital admission. Further antecedent factors and resuscitation characteristics were collected for these patients. RESULTS: There were 257 IHCA, of which 115 (44.7%) occurred on general wards, with 19.8% of all patients surviving to discharge home. There were 39 (15.2%) instances of non-beneficial CPR, of which 28 (72%) of 39 occurred in unmonitored patients on the ward comprising nearly one-quarter (28/115) of all arrests in this patient group. A specialist had reviewed 30 (76.9%) of 39 of these patients, and 33.3% (13/39) had a medical emergency team (MET) review prior to their arrest. CONCLUSIONS: Over one in seven resuscitation attempts were non-beneficial. MET reviews and specialist ward rounds provide opportunities to improve the documentation and visibility of NFR status.

Gout and diabetes: a common combination.

The aims of this cross-sectional study were to compare metabolic parameters in people with gout and diabetes with gout only and type 2 diabetes mellitus (T2DM) only. Fifty General Practices in NHS Ayrshire and Arran (population 340 377) contributed data. The sample was split into three groups, those with both gout and T2DM, those with gout only and those with T2DM only. The prevalence of gout in Ayrshire and Arran was 2.65%. The prevalence of gout in people with type 1 and 2 diabetes was 1.90% (p=0.30) and 10.12% (p<10(-5)), respectively. Patients with both conditions were significantly more likely to be male (p<10(-5)), older (p<10(-5)), have a higher mean body mass index (p<0.001), higher triglycerides (p<10(-4)), lower mean total, high-density lipoprotein- and low-density lipoprotein cholesterol (p<10(-5)), lower estimated glomerular filtration rate (p<0.001), neuropathy (p=0.02), lower haemoglobin (p<0.001), to be prescribed more medications (p<10(-5)) and less likely to smoke (p<0.01). There was an association between lower haemoglobin A1c and increased prevalence of gout (p<0.001). 42.4% of patients with gout alone and 36.2% of those with both gout and diabetes had a urate measure. This study defines much more clearly the association between gout and T2DM. Of interest, in terms of lifestyle, both better glycaemic control and smoking are associated with a higher prevalence of gout.

Techniques of extracorporeal cytokine removal: a systematic review of human studies.

BACKGROUND AND AIMS: Hypercytokinemia is believed to be harmful and reducing cytokine levels is considered beneficial. Extracorporeal blood purification (EBP) techniques have been studied for the purpose of cytokine reduction. We aimed to study the efficacy of various EBP techniques for cytokine removal as defined by technical measures. METHOD: We conducted a systematic search for human clinical trials which focused on technical measures of cytokine removal by EBP techniques. We identified 41 articles and analyzed cytokine removal according to clearance (CL), sieving coefficient (SC), ultrafiltrate (UF) concentration and percentage removed. RESULTS: We identified the following techniques for cytokine removal: standard hemofiltration, high volume hemofiltration (HVHF), high cut-off (HCO) hemofiltration, plasma filtration techniques, and adsorption techniques, ultrafiltration (UF) techniques relating to cardiopulmonary bypass (CPB), extracorporeal liver support systems and hybrid techniques including combined plasma filtration adsorption. Standard filtration techniques and UF techniques during CPB were generally poor at removing cytokines (median CL for interleukin 6 [IL-6]: 1.09 mL/min, TNF-alpha 0.74 mL/min). High cut-off techniques consistently offered moderate cytokine removal (median CL for IL-6: 26.5 mL/min, interleukin 1 receptor antagonist [IL-1RA]: 40.2 mL/min). Plasma filtration and extracorporeal liver support appear promising but data are few. Only one paper studied combined plasma filtration and adsorption and found low rates of removal. The clinical significance of the cytokine removal achieved with more efficacious techniques is unknown. CONCLUSION: Human clinical trials indicate that high cut-off hemofiltration techniques, and perhaps plasma filtration and extracorporeal liver support techniques are likely more efficient in removing cytokines than standard techniques.

Techniques of extracorporeal cytokine removal: a systematic review of the literature.

BACKGROUND AND AIMS: Attempts at achieving cytokine homeostasis include blood purification to deliver cytokine removal. Assessment of ex vivo studies for optimal operating conditions is a vital step. METHODS: We conducted a systematic search for ex vivo studies on cytokine removal using known modalities of extracorporeal circulation. We selected 29 articles and analyzed data according to clearance, sieving coefficient, ultrafiltrate concentration and percentage removal. RESULTS: We identified four main techniques for cytokine removal: standard techniques, high cut-off (HCO) techniques, adsorption techniques and combined plasma filtration adsorption. HCO hemofiltration (HCO/HF) showed greatest consistency in cytokine removal among all approaches. Mean albumin clearance with HCO filters was 3.74 ml/min. CONCLUSION: Ex vivo data support the view that HCO/HF is the most consistently effective approach in terms of sieving and clearance. Further investigation of HCO/HF in randomized controlled trials in animal models and humans seems desirable.

Apremilast in the treatment of psoriatic arthritis: a perspective review.

Apremilast is an orally-active small molecule which inhibits phosphodiesterase-4 (PDE4). Clinical trials have demonstrated its efficacy and safety in psoriatic arthritis (PsA) and psoriasis. Established therapeutic options have variable effectiveness across the different domains of psoriatic disease. Whilst biologic therapies have proven to be of significant benefit to many patients, not all patients respond, and others are not eligible or do not tolerate biologic therapy. We review the mechanism of action, pharmacokinetics and clinical trial data with regards to both efficacy and safety for apremilast and consider where this new treatment may be positioned in the treatment of PsA.

Evaluation of the ACRRM national radiology program for Australian rural and remote medical practitioners.

INTRODUCTION: In 2000, the Australian College of Rural and Remote Medicine (ACRRM) developed a national radiology quality assurance (QA) and continuing medical education (CME) program for rural and remote non-specialist Australian doctors. The program commenced on 1 January 2001. It required rural doctors to obtain 30 radiology QA/CME points over a 4 year period. At least 15-20 of these points had to be obtained by one of two mandatory options of the program, either: (1) film interpretation, report and review clinical audit activity; or (2) a radiology clinical attachment. METHOD: Doctors submitted their completed film review forms and clinical attachment logbooks to the program manager as confirmation of their educational activity to receive their professional development points. Data from film review forms and clinical attachment logbooks were de-identified and entered into two Microsoft EXCEL spreadsheets. The data were categorised and analysed in EXCEL. RESULTS: From 1 January 2001 to September 2004, 823 rural and remote doctors enrolled in the ACRRM radiology program. This included 281 locums who enrolled in the short-term locum option of the program and 563 doctors who enrolled in the full program. In September 2004, 419 doctors had completed a radiology film review with a radiologist and 41 doctors completed a radiology clinical attachment in 31 different public and private radiology practices. One hundred and ninety-five doctors completed the short-term locum activity. Ninety-two different specialist radiologists participated in the program and assisted rural and remote doctors to enhance their radiology knowledge, confidence and skills. This article describes results from the two mandatory activities. CONCLUSION: The evaluation of the ACRRM radiology program after its first 3 years and 9 months shows there are a large number of rural and remote Australian doctors undertaking professional development and quality assurance activities in radiology.

Techniques of extracorporeal cytokine removal: a systematic review of the literature on animal experimental studies.

BACKGROUND AND AIMS: Extracorporeal cytokine removal may be desirable. We sought to assess extracorporeal blood purification (EBP) techniques for cytokine removal in experimental animal studies.
 METHODS: We conducted a targeted, systematic search and identified 17 articles. We analyzed cytokine clearance, sieving coefficient (SC), ultrafiltrate (UF) concentration, and percentage removal. As this review concerns technical appraisal of EBP techniques, we made no attempts to appraise the methodology of the studies included. Results are in descriptive terms only.
 RESULTS: Applying predicted clearance for 80 kg human, high volume hemofiltration (HVHF) techniques and plasmafiltration (PF) showed the highest rates of cytokine removal. High cutoff (HCO)/HF and PF techniques showed modest ability to clear cytokines using low to medium flows. Standard hemofiltration had little efficacy. At higher flows, HCO/HF achieved clearances between 30 and 70 ml/min for IL-6 and IL-10. There was essentially no removal of tumor necrosis factor (TNF)-alpha outside of PF.
 CONCLUSIONS: Experimental animal studies indicate that HVHF (especially with HCO filters) and plasmafiltration have the potential to achieve appreciable IL-6 and IL-10 clearances. However, only PF can remove TNF-alpha reliably.

Mental health policy--stumbling in the dark?

Over the past 15 years, governments have agreed to a series of National Mental Health Plans. These national strategies and plans have set goals and discussed the importance of monitoring and evaluation. Despite this ongoing national collaborative framework, Australia's mental health policy lacks real accountability and relies largely on limited mental health service systems data. The lack of outcome data represents a critical gap in knowledge for mental health policy, planning and practice. Resistance from current stakeholders and a lack of investment in research and monitoring capacity are preventing more rigorous ongoing monitoring of mental health policy. The new Rudd Government appears to be shifting the emphasis towards measuring the outcomes of national policy in health, housing and employment. Measuring such outcomes will guide government decision making and ultimately improve mental health services.

Late-onset ornithine transcarbamylase deficiency: a potentially fatal yet treatable cause of coma.

Hyperammonaemia due to ornithine transcarbamylase (OTC) deficiency is a well-described cause of coma in neonates. Rarely, adults with this disorder may also present with coma. Here we describe the first reported case, to our knowledge, in a pregnant woman. She was successfully treated with metabolic therapy and, contrary to usual paediatric practice, renal replacement therapy. We review the biochemistry of OTC deficiency and other urea cycle disorders, and discuss the physiological rationale and evidence base for treatment of this condition. We highlight the need to consider hyperammonaemia in the differential diagnosis of coma.
