Antibiotic allergy testing programs will ensure that vulnerable patients receive appropriate antibiotic therapy

Antibiotic allergy labels are accumulated by various mechanisms and are often incorrectly self-reported or recorded. Incorrect antibiotic allergy labels frequently persist in community and hospital medical records throughout patients’ health care journeys, either with the phenotype unverified by clinicians or recorded as unknown.1,2 Among a cohort of older Australian general medical inpatients, we identified that 25% had a mismatch between their reported and recorded antibiotic allergy.3 Further, as an additional source of incorrect antibiotic allergy labels, patients with a true immunological basis for antibiotic allergy, such as immediate (IgE-mediated) reactions, may lose reactivity over time.4 Incorrect antibiotic allergy labels often prevent the use of appropriate narrow spectrum penicillin and targeted antibiotic therapies in both community and hospital practice, frequently among the patients most in need.4,5

Transcranial magnetic stimulation: an item number is justified

Med J Aust 2018; 208 (11): . || doi: 10.5694/mja17.00849
Published online: 18 June 2018

Evidence shows that transcranial magnetic stimulation is a safe and effective treatment for drug-resistant depression

Depression is the leading cause of disability globally.1 The condition is painful for the patient (and may end in suicide), distressing for relatives and friends and challenging to clinicians. One-third of patients with depression do not respond to the first antidepressant medication, the likelihood of achieving remission diminishes with each additional medication, and one-third will not respond to any known medication.2

Australian standards of care and treatment guidelines for transgender and gender diverse children and adolescents

Michelle M Telfer, Michelle A Tollit, Carmen C Pace and Ken C Pang
Med J Aust 2018; 209 (3): . || doi: 10.5694/mja17.01044

Abstract

Introduction: The Australian standards of care and treatment guidelines aim to maximise quality care provision to transgender and gender diverse (TGD) children and adolescents across Australia, while recognising the unique circumstances of providing such care to this population. Recommendations are made based on available empirical evidence and clinician consensus, and have been developed in consultation with Australian professionals from multiple disciplines working with the TGD population, TGD support organisations, as well as TGD children and adolescents and their families.

Main recommendations: Recommendations include general principles for supporting TGD children and adolescents using an affirmative approach, separate guidelines for the care of pre-pubertal children and TGD adolescents, as well as discipline-based recommendations for mental health care, medical and surgical interventions, fertility preservation, and speech therapy.

Changes in management as a result of this statement: Although published international treatment guidelines currently exist, challenges in accessing and providing TGD health care specific to Australia have not been addressed to date. In response to this, these are the first guidelines to be developed for TGD children and adolescents in Australia. These guidelines also move away from treatment recommendations based on chronological age, with recommended timing of medical transition and surgical interventions dependent on the adolescent’s capacity and competence to make informed decisions, duration of time on puberty suppression, coexisting mental health and medical issues, and existing family support.

Lung transplantation in Australia, 1986–2018: more than 30 years in the making

Miranda A Paraskeva, Kovi C Levin, Glen P Westall and Gregory I Snell
Med J Aust 2018; 208 (10): . || doi: 10.5694/mja17.00909

Summary

 

  • Lung transplantation in Australia is 32 years old in 2018. From its early infancy in 1986, it continues to evolve and is internationally recognised as demonstrating world’s best practices in organ donation, utilisation and transplantation procedures.
  • Over the past decade, transplant numbers have increased substantially due to innovations in donor procurement, such as donation after circulatory death, the use of ex vivo lung perfusion, extended criteria and organ utilisation, with more than 200 lung transplants undertaken in Australia annually. Parallel to this, lung transplant outcomes have continued to improve.
  • While the management of lung transplant recipients is heavily dependent on a tertiary care paradigm, this model is well developed and has been extremely successful, with Australian outcomes exceeding those of the International Society for Heart and Lung Transplantation Registry at all time points.

Abstract

Objective: To compare the outcomes and costs of clustered domestic and standard Australian models of residential aged care.

Design: Cross-sectional retrospective analysis of linked health service data, January 2015 – February 2016.

Setting: 17 aged care facilities in four Australian states providing clustered (four) or standard Australian (13) models of residential aged care.

Participants: People with or without cognitive impairment residing in a residential aged care facility (RACF) for at least 12 months, not in palliative care, with a family member willing to participate on their behalf if required. 901 residents were eligible; 541 consented to participation (24% self-consent, 76% proxy consent).

Main outcome measures: Quality of life (measured with EQ-5D-5L); medical service use; health and residential care costs.

Results: After adjusting for patient- and facility-level factors, individuals residing in clustered models of care had better quality of life (adjusted mean EQ-5D-5L score difference, 0.107; 95% CI, 0.028–0.186; P = 0.008), lower hospitalisation rates (adjusted rate ratio, 0.32; 95% CI, 0.13–0.79; P = 0.010), and lower emergency department presentation rates (adjusted rate ratio, 0.27; 95% CI, 0.14–0.53; P < 0.001) than residents of standard care facilities. Unadjusted facility running costs were similar for the two models, but, after adjusting for resident- and facility-related factors, it was estimated that overall there is a saving of $12 962 (2016 values; 95% CI, $11 092–14 831) per person per year in residential care costs.

Conclusions: Clustered domestic models of residential care are associated with better quality of life and fewer hospitalisations for residents, without increasing whole of system costs.

Low risk prostate cancer and an opportunity lost: more activity required in active surveillance

David P Smith and Gary A Wittert
Med J Aust 2018; 208 (10): . || doi: 10.5694/mja18.00209

Men who are being monitored may be more open to interventions for improving their general health and quality of life

Prostate cancer is the most frequently registered cancer in Australian men, with an estimated 17 729 new diagnoses in 2018.1 For the 25% who are diagnosed with low risk disease, active surveillance (AS) is now the recommended management strategy, as their cancer may never progress.2 Avoiding or at least postponing radical treatment reduces the quality of life risks associated with surgery or radiation therapy. However, there is no evidence-based consensus about the optimal approach to surveillance, and practices differ between countries with regard to the type, frequency, and sequence of follow-up.3 AS differs from “watchful waiting” in that it has a curative intent; watchful waiting involves less intense routine monitoring, intervening only when symptoms appear. One standard approach to AS recommends prostate-specific antigen (PSA) assessment every 3–6 months, a digital rectal examination at least once a year, and at least one biopsy within 12 months of diagnosis, followed by serial biopsy every 2–5 years.

Better biomarkers are needed to ensure early and accurate detection and prognosis of prostate cancer

Prostate cancer is now the most common cancer diagnosed in men in Australia,1 and Australia has one of the highest incidence rates of prostate cancer in the world, with an estimated age-standardised rate of 119.2 per 100 000 men.2 Before 1960, the primary diagnostic test for prostate cancer was the prostatic acid phosphatase test. This was eventually replaced in the 1980s by the prostate-specific antigen (PSA) test.

Abstract

Objective: To characterise the practice of active surveillance (AS) for men with low risk prostate cancer by examining the characteristics of those who commence AS, the rate of adherence to accepted AS follow-up protocols over 2 years, and factors associated with good adherence.

Design, setting: Retrospective cohort study; analysis of data collected from 38 sites participating in the Prostate Cancer Outcomes Registry–Victoria.

Participants: Men diagnosed with prostate cancer between August 2008 and December 2014 aged 75 years or less at diagnosis, managed by AS for at least 2 years, and with an ISUP grade group of 3 or less (Gleason score no worse than 4 + 3 = 7).

Main outcome measures: Adherence to an AS schedule consisting of at least three PSA measurements and at least one biopsy in the 2 years following diagnosis.

Results: Of 1635 men eligible for inclusion in the analysis, 433 (26.5%) adhered to the AS protocol. The significant predictor of adherence in the multivariate model was being diagnosed in a private hospital (v public hospital: adjusted odds ratio [aOR], 1.83; 95% CI, 1.42–2.37; P < 0.001). Significant predictors of non-adherence included being diagnosed by transurethral resection of the prostate (v transrectal ultrasound biopsy [TRUS]: OR, 0.54; 95% CI, 0.39–0.77; P < 0.001) or transperineal biopsy (v TRUS: OR, 0.32; 95% CI, 0.19–0.52; P < 0.001), and being 66 years of age or more at diagnosis (v < 55 years: OR, 0.65; 95% CI, 0.45–0.92; P = 0.015).

Conclusion: Almost three-quarters of men who had prostate cancer with low risk of disease progression did not have follow-up investigations consistent with standard AS protocols. The clinical consequences of this shortcoming are unknown.

Virtual medicine: how virtual reality is easing pain, calming nerves and improving health

Virtual reality is thought to create an immersive distraction that restricts the mind from processing pain

Not so far in the future, doctors might prescribe a virtual beach vacation to calm aches and pains, in lieu of pharmacotherapy. Insurance companies might offer scenic tours of Icelandic fjords to lower blood pressure, instead of doubling up on drugs. Psychiatrists might treat social phobia by inviting patients to a virtual dinner party. Hospitals may immerse children in a fantastical playland while they receive chemotherapy.

Impact of ethnicity on the natural history of Parkinson disease

Summary

 

  • Parkinson disease (PD) affects people of all races and ethnicity worldwide.
  • PD is a multineurotransmitter and multisystem disorder and our current concept of the natural history of PD has changed considerably over the past decades.
  • Many aspects of this heterogeneous condition still remain unexplained; one aspect that is poorly studied is the role of ethnicity and manifest motor and non-motor PD.
  • Some preliminary data suggest that the prodromal risk of developing PD, clinical symptom expression and the experience of living with the condition may vary between different ethnic groups.
  • Several factors might play a role in the influence of ethnicity on PD, such as pharmacogenetics, sociocultural aspects and environmental exposures.
  • Increased knowledge on the role of ethnicity in PD may help shed light on the symptom expression and treatment response of PD, address inequalities in health care delivery worldwide and improve the delivery of personalised medicine.
