The development of practice standards for radiation oncology in Australia: a tripartite approach

Quality management in radiotherapy treatment delivery

Radiation Oncology continues to rely on accurate delivery of radiation, in particular where patients can benefit from more modulated and hypofractioned treatments that can deliver higher dose to the target while optimising dose to normal structures. These deliveries are more complex, and the treatment units are more computerised, leading to a re-evaluation of quality assurance (QA) to test a larger range of options with more stringent criteria without becoming too time and resource consuming. This review explores how modern approaches of risk management and automation can be used to develop and maintain an effective and efficient QA programme. It considers various tools to control and guide radiation delivery including image guidance and motion management. Links with typical maintenance and repair activities are discussed, as well as patient-specific quality control activities. It is demonstrated that a quality management programme applied to treatment delivery can have an impact on individual patients but also on the quality of treatment techniques and future planning. Developing and customising a QA programme for treatment delivery is an important part of radiotherapy. Using modern multidisciplinary approaches can make this also a useful tool for department management.

'With great power comes great responsibility': An impetus for quality and safety in radiation oncology

Strict quality control and vigilance at every step is essential to maintain rigour and ensure quality and safety in radiation oncology. The scientific knowledge and technological capabilities we possess give us enormous power to deliver specialised and complex treatments and improve health outcomes for our cancer patients. However, this requires development of whole system performance and its evaluation against established standards and benchmarks. It calls for organisational commitment and active participation of managers and clinical teams in quality improvement initiatives. In addition to medical physicists and radiation therapist, radiation oncologists, including trainees, must accept important leadership responsibilities to maintain a positive safety culture.

Developing gender-specific evidence-based standards to improve the health and wellbeing of women in prison in England: a literature review and modified eDelphi survey

PURPOSE

There are significant health inequalities experienced by women in prison. They face distinct challenges and have particular and complex needs, specifically with regard to their physical and mental health. The purpose of this paper is to describe the approach taken to develop a set of health and wellbeing standards for the women's prison estate in England, which can be applied elsewhere.

DESIGN/METHODOLOGY/APPROACH

A structured literature review of standard healthcare databases and grey literature was used to inform development of suggested standards. A multidisciplinary expert panel provided consensus on the standards through an online survey and women with a history of contact with the criminal justice system were consulted through consensus groups.

FINDINGS

A total of 549 papers were included in the final review. From this, 127 standards were identified for inclusion in the Delphi process. Consensus was achieved on all standards; this, combined with the analysis of qualitative feedback provided by both the survey and the consensus groups, resulted in the development of 6 overarching principles and 122 standards, across ten topic areas.

ORIGINALITY/VALUE

These standards are the most extensive that are known to exist for health and wellbeing of women in prison and the first to be developed in England. The process used ensures the standards have high validity, acceptability and feasibility and can be used to support those developing similar methodologies. There are few papers which document the development of standards to improve health and to the authors knowledge, only one other paper has been published detailing the development of health standards in prison settings specifically.

Establishment of practice standards in nomenclature and prescription to enable construction of software and databases for knowledge-based practice review

INTRODUCTION

Establishment of standards within a practice and across disease site groups for nomenclatures, prescription formatting, and measured dose-volume histogram (DVH) metrics is a key enabling step for creating software and database solutions to make routine aggregation of dosimetric data for all patients treated in a practice, practical. A process of physician-driven, iterative dialogs coupled with development of technical tools is required to implement the cultural and procedural changes. The cumulative reward for this effort is a database that can be used for defining practice norms, benchmarking against national standards, and tracking dosimetric effects of longitudinal practice pattern changes.

METHODS AND MATERIALS

A 4-year project was carried out to develop and introduce standardizations, modify processes, and develop computer-based tools for reporting, aggregation, and analysis of prescription and DVH metrics. Physician disease site groups developed 42 target and 81 normal tissue templates. From the database of 32,002 DVH metrics, benchmarking was illustrated for a subgroup of breast (281) and prostate (324) patients treated with conventional fractionation over a 16-month period. Breast patients were segregated according to prescription template used: simple (S, tangents only) vs complex (C, tangents + supraclavicular ± intramammary nodes) and left (S-L or C-L) versus right (S-R or C-R).

RESULTS

Prostate patients' median and 50% confidence intervals (CIs) for bladder, stated according to the nomenclature: the percentage of bladder volume receiving doses of ≥40 Gy (V40[%]), V65Gy[%], V70Gy[%], V75Gy[%], and V80Gy[%] were 45.5 (24.9-57.0), 15.6 (9.0-23.8), 7.6 (3.3-13.6), 2.0 (0.0-7.9), and 0.0 (0.0-1.4), respectively. Values for rectum: V50Gy[%], V60 Gy[%], V65Gy[%], V70Gy[%], and V75Gy[%] were 37.1 (27.8-43.5), 21.8 (15.6-25.5), 14.6 (9.6-18.0), 7.7 (1.9-12.3), and 1.0 (0-7.0), respectively. For breast patients, heart:mean Gray values were 1.5 (1.0-2.0), 3.1 (2.2-4.8), 0.4 (0.3-0.7), and 1.1 (0.8-2.2) for S-L, C-L, S-R, and C-R, respectively. Longitudinal, moving window plots of median, 50% CI, and 90% CI for 6-month periods demonstrated the effect of practice changes to reduce heart doses.

CONCLUSIONS

Standardization was challenging as a practice change, but has resulted in significant improvements for both our clinical and research efforts.
