Developing an Australian Melanoma Clinical Outcomes Registry (MelCOR): a protocol paper.

INTRODUCTION: Australia has the highest incidence of melanoma in the world with variable care provided by a diverse range of clinicians. Clinical quality registries aim to identify these variations in care and provide anonymised, benchmarked feedback to clinicians and institutions to improve patient outcomes. The Australian Melanoma Clinical Outcomes Registry (MelCOR) aims to collect population-wide, clinical-level data for the early management of cutaneous melanoma and provide anonymised feedback to healthcare providers. METHODS AND ANALYSIS: A modified Delphi process will be undertaken to identify key clinical quality indicators for inclusion in the MelCOR pilot. MelCOR will prospectively collect data relevant to these quality indicators, initially for all people over the age of 18 years living in Victoria and Queensland with a melanoma diagnosis confirmed by histopathology, via a two-stage recruitment and consent process. In stage 1, existing State-based cancer registries contact the treating clinician and provide an opportunity for them to opt themselves or their patients out of direct contact with MelCOR. After stage 1, re-identifiable clinical data are provided to the MelCOR under a waiver of consent. In stage 2, the State-based cancer registry will approach the patient directly and invite them to opt in to MelCOR and share identifiable data. If a patient elects to opt in, MelCOR will be able to contact patients directly to collect patient-reported outcome measures. Aggregated data will be used to provide benchmarked, comparative feedback to participating institutions/clinicians. ETHICS AND DISSEMINATION: Following the successful collection of pilot data, the feasibility of an Australia-wide roll out will be evaluated. Key quality indicator data will be the core of the MelCOR dataset, with additional data points added later. Annual reports will be issued, first to the relevant stakeholders followed by the public. MelCOR is approved by the Alfred Ethics Committee (58280/127/20).

Physical component quality of life reflects the impact of time and moderate chronic kidney disease, unlike SF-6D utility and mental component SF-36 quality of life: An AusDiab analysis.

AIM: Assessing the impact of interventions on the patient experience requires measures that are plausibly responsive to change. In a community cohort of people with and without chronic kidney disease (CKD) markers at baseline, we aimed to evaluate change in commonly used measures of quality of life (QOL) over the passage of 5 years. METHODS: Included were 6400 participants in the Australian Diabetes, Obesity and Lifestyle (AusDiab) surveys with baseline and 5-year CKD and QOL measures. Changes in SF-6D utility, and the Medical Outcomes Study 36-Item Short Form (SF-36) physical (PCS) and mental (MCS) component summary scores, were evaluated with regression analyses according to the baseline presence of reduced estimated glomerular filtration rate (eGFR) (CKD-Epidemiology Collaboration eGFR ≤60 m/min per 1.73 m2 ) or albuminuria (urine albumin:creatinine ratio ≥3.4 mg/mmol). RESULTS: At baseline, eGFR was reduced in 2.4% of participants and 5.1% had albuminuria. Participants with reduced eGFR had a lower SF-6D and PCS, and those with albuminuria a lower PCS, compared with those without, but the differences were explained by known confounders. MCS scores were not affected by the presence of reduced eGFR or albuminuria. Over 5 years all groups exhibited stable SF-6D and MCS scores but declining unadjusted PCS scores. PCS decline was greater for those with reduced eGFR, and remained significant after adjustment (-2.7 (-4.1 to -1.3) vs. -0.8 (-1.1 to -0.6, P < 0.01). Analyses according to CKD stages were essentially unchanged. CONCLUSION: Utility and mental QOL appears stable over 5 years, unaffected by time or markers of CKD health. Physical QOL appeared to deteriorate with time, especially for those with CKD, making it a more likely candidate assessment measure for intervention and health service evaluations.

Considering health equity when moving from evidence-based guideline recommendations to implementation: a case study from an upper-middle income country on the GRADE approach.

The availability of evidence-based guidelines does not ensure their implementation and use in clinical practice or policy making. Inequities in health have been defined as those inequalities within or between populations that are avoidable, unnecessary and also unjust and unfair. Evidence-based clinical practice and public health guidelines ('guidelines') can be used to target health inequities experienced by disadvantaged populations, although guidelines may unintentionally increase health inequities. For this reason, there is a need for evidence-based clinical practice and public health guidelines to intentionally target health inequities experienced by disadvantaged populations. Current guideline development processes do not include steps for planned implementation of equity-focused guidelines. This article describes nine steps that provide guidance for consideration of equity during guideline implementation. A critical appraisal of the literature followed by a process to build expert consensus was undertaken to define how to include consideration of equity issues during the specific GRADE guideline development process. Using a case study from Colombia we describe nine steps that were used to implement equity-focused GRADE recommendations: (1) identification of disadvantaged groups, (2) quantification of current health inequities, (3) development of equity-sensitive recommendations, (4) identification of key actors for implementation of equity-focused recommendations, (5) identification of barriers and facilitators to the implementation of equity-focused recommendations, (6) development of an equity strategy to be included in the implementation plan, (7) assessment of resources and incentives, (8) development of a communication strategy to support an equity focus and (9) development of monitoring and evaluation strategies. This case study can be used as model for implementing clinical practice guidelines, taking into account equity issues during guideline development and implementation.

Evolution and Divergence of H3N8 Equine Influenza Viruses Circulating in the United Kingdom from 2013 to 2015.

Equine influenza viruses (EIV) are a major cause of acute respiratory disease in horses worldwide and occasionally also affect vaccinated animals. Like other influenza A viruses, they undergo antigenic drift, highlighting the importance of both surveillance and virus characterisation in order for vaccine strains to be kept up to date. The aim of the work reported here was to monitor the genetic and antigenic changes occurring in EIV circulating in the UK from 2013 to 2015 and to identify any evidence of vaccine breakdown in the field. Virus isolation, reverse transcription polymerase chain reaction (RT-PCR) and sequencing were performed on EIV-positive nasopharyngeal swab samples submitted to the Diagnostic Laboratory Services at the Animal Health Trust (AHT). Phylogenetic analyses were completed for the haemagglutinin-1 (HA1) and neuraminidase (NA) genes using PhyML and amino acid sequences compared against the current World Organisation for Animal Health (OIE)-recommended Florida clade 2 vaccine strain. Substitutions between the new isolates and the vaccine strain were mapped onto the three-dimensional structure protein structures using PyMol. Antigenic analyses were carried out by haemagglutination inhibition assay using a panel of post-infection ferret antisera. Sixty-nine outbreaks of equine influenza in the UK were reported by the AHT between January 2013 and December 2015. Forty-seven viruses were successfully isolated in eggs from 41 of the outbreaks. Only three cases of vaccine breakdown were identified and in each case the vaccine used contained a virus antigen not currently recommended for equine influenza vaccines. Nucleotide sequencing of the HA and NA genes revealed that all of the viruses belonged to the Florida clade 2 sub-lineage of H3N8 EIV. Phylogenetic and sequence analyses showed that the two sub-populations, previously identified within clade 2, continued to circulate and had accrued further amino acid substitutions. Antigenic characterisation using post-infection ferret antisera in haemagglutination inhibition assays however, failed to detect any marked antigenic differences between the isolates. These findings show that Florida clade 2 EIV continue to circulate in the UK and support the current OIE recommendation to include an example of Florida clade 2 in vaccines.

Barriers to managing TB in emergency departments.

Improved management of tuberculosis is a key priority for Public Health England due to unacceptably high rates of the disease in the UK, particularly in London and other major cities. A survey of 20 staff in the acute medical unit at Queen Alexandra Hospital, Portsmouth, explored potential barriers to early TB detection and infection control in busy emergency departments. Low awareness and little familiarity with TB among many emergency admissions staff increased the likelihood of transmission from undiagnosed patients in crowded waiting areas. The study suggested regular updates on TB so staff could refresh their knowledge and awareness, and help improve TB detection and infection control.
