Development of a binational thyroid cancer clinical quality registry: a protocol paper

INTRODUCTION

The occurrence of thyroid cancer is increasing throughout the developed world and since the 1990s has become the fastest increasing malignancy. In 2014, a total of 2693 Australians and 302 New Zealanders were diagnosed with thyroid cancer, with this number projected to rise to 3650 in 2018. The purpose of this protocol is to establish a binational population-based clinical quality registry with the aim of monitoring and improving the quality of care provided to patients diagnosed with thyroid cancer in Australia and New Zealand.

METHODS AND ANALYSIS

The Australian and New Zealand Thyroid Cancer Registry (ANZTCR) aims to capture clinical data for all patients over the age of 16 years with thyroid cancer, confirmed by histopathology report, who have been diagnosed, assessed or treated at a contributing hospital. A multidisciplinary steering committee was formed which, with operational support from Monash University, established the ANZTCR in early 2017. The pilot phase of the registry is currently operating in Victoria, New South Wales, Queensland, Western Australia and South Australia, with over 20 sites expected to come on board across Australia in 2018. A modified Delphi process was undertaken to determine the clinical quality indicators to be reported by the registry, and a minimum data set was developed comprising information regarding thyroid cancer diagnosis, pathology, surgery and 90-day follow-up.

FUTURE PLANS

The establishment of the ANZTCR provides the opportunity for Australia and New Zealand to further understand current practice in the treatment of thyroid cancer and identify variation in outcomes. The engagement of endocrine surgeons in supporting this initiative is crucial. While the pilot registry has a focus on early clinical outcomes, it is anticipated that future collection of longer term outcome data particularly for patients with poor prognostic disease will add significant further value to the registry.

Improving surgical outcomes for patients with cancer: an Australian perspective

The quality of surgical outcomes for cancer patients is influenced by multiple factors that must be addressed by both a systemic and an individual surgeon approach. In Australia, like many other countries, changes to the health care system via both federal and state government health care quality agencies are likely to positively impact outcomes for surgical patients. Surgical audit is an important component of quality surgical practice and the most successful surgical audit in Australia is the National Breast Cancer Audit, run by the Royal Australasian College of Surgeons. The audit has helped to document the standard of breast cancer surgery in Australia and New Zealand and in the process identified areas for improvement.

Treatment and survival from breast cancer: the experience of patients at South Australian teaching hospitals between 1977 and 2003

RATIONALE

Treatment guidelines recommend a more conservative surgical approach than mastectomy for early stage breast cancer and a stronger emphasis on adjuvant therapy. Registry data at South Australian teaching hospitals have been used to monitor survivals and treatment in relation to these guidelines.

AIMS AND OBJECTIVES

To use registry data to: (1) investigate trends in survival and treatment; and (2) compare treatment with guidelines.

METHODS

Registry data from three teaching hospitals were used to analyse trends in primary courses of treatment of breast cancers during 1977-2003 (n=4671), using univariate analyses and multiple logistic regression. Disease-specific survivals were analysed using Kaplan-Meier product limit estimates and multivariable Cox proportional hazards regression.

RESULTS

The 5-year survival was 79.9%, but with a secular increase, reaching 83.6% in 1997-2003. The relative risk of death (95% confidence limits) was 0.74 (0.62, 0.88) for 1997-2003, compared with previous diagnoses, after adjusting for tumour node metastasis stage, grade, age and place of residence. Treatment changes included an increase in conservative surgery (as opposed to mastectomy) from 51.7% in 1977-1990 to 76.8% in 1997-2003 for stage I (P<0.001) and from 31.1% to 52.2% across these periods for stage II (P<0.001). Adjuvant radiotherapy also became more common (P<0.001), with 20.6% of patients receiving this treatment in 1977-1990 compared with 60.7% in 1997-2003. Radiotherapy generally was more prevalent when conservative surgery was provided, although also relatively common in mastectomy patients when tumour diameters exceeded 50 mm or when there were four or more involved nodes. The proportion of patients receiving chemotherapy increased (P<0.001), from 19.6% in 1977-1990 to 36.9% in 1997-2003, and the proportion having hormone therapy also increased (P<0.001), from 34.3% to 59.4% between these periods.

CONCLUSIONS

Survivals appear to be increasing and treatment trends are broadly consistent with guideline directions, and the earlier research on which these recommendations were based.

GUIDELINES FOR SURGICAL AUDIT IN AUSTRALIA AND NEW ZEALAND

Surgical audit is an important part of the process to measure performance, reduce clinical risk and improve quality of care. Recognizing this, the Royal Australasian College of Surgeons established a Surgical Audit Taskforce as a subcommittee of the Board of Continuing Professional Standards. This study aims to review the recommendations of the Taskforce for data collection and peer review. The minimum data for whole-practice, continuing audit have been defined. The method of data collection, devices and databases are personal choices for the individual surgeon. However, there are many benefits of developing an electronic surgical audit, and these include facilitating comparison and sharing of audit data between units. Surgical audits should not only report on work carried out but also ensure that outcomes include key performance indicators such as major complications, readmissions, reoperations, transfers, incident reports, complaints and mortalities. Effective clinical governance demands that issues raised by audit need to be documented and reported together with recommendations for improvement. Surgeons should be proactive in helping to find and implement solutions to the issues arising from surgical audit.

National Breast Cancer Audit: establishing a web-based data system

BACKGROUND

An audit of surgical treatment of early breast cancer was introduced nationally in 1999. In August 2002, the Australian Safety and Efficacy Register of New Interventional Procedures - Surgical, under the auspices of the Royal Australasian College of Surgeons, assumed responsibility for managing this audit. This article provides an update of audit activities, now known formally as the National Breast Cancer Audit (NBCA), including a description of the new governance structure and the development of a secure online surgical audit system.

METHODS

Major changes have taken place in the design and governance of the NBCA during the last two years. Two committees have been established to oversee the audit. A clinical advisory committee comprises experts from a number of fields including breast surgery, oncology, government, and from peak breast cancer and consumer bodies. A technical advisory committee oversees many of the technical issues that have arisen with the development of an online data entry system. The online system of data entry was developed and launched to surgeons in May 2004.

RESULTS

There are now 28,000 cases of primary breast surgery in the audit. Around 250 surgeons are currently participating, an increase of over 50 surgeons since May 2004. Surgeons can review their data using the online system and compare their own results by generating reports which graph their own results against national aggregate data.

CONCLUSIONS

There has been a significant increase in the volume of data received since the launch of the secure online system. The governing committees are working towards creating a clinical audit which will provide an improved data entry system and better reporting for all participating surgeons. The NBCA can also serve as a template on which to base other surgical audits.

Surgical management of invasive breast cancer: a 5-year prospective study of treatment in the Australian Capital Territory and South-Eastern New South Wales

BACKGROUND

Breast cancer is a major health problem in Australia. The aim of the present report is to evaluate the surgical management of invasive breast cancers in our region.

METHODOLOGY

As part of a multidisciplinary quality assurance project, data were collected for the majority of breast cancers treated in our region between July 1997 and June 2002. Participants included surgeons, medical and radiation oncologists, pathologists and general practitioners.

RESULTS

Over the 5-year period, 1069 invasive breast cancers were treated. Mastectomy (52%) was more common than breast conservation. For cancers less than 2 cm in diameter (61%), breast conservation was achieved in 62%. High nuclear grade cancers (27%) resulted in mastectomy in 60%. This treatment pattern was the same for patients living in urban and rural areas and in all age groups. Those patients requiring two or more operations (30%) to achieve surgical clearance still had a 33% rate of breast conservation. Over the last 5 years there has been an increase in sentinel node biopsies (16 sentinel node biopsies during 1998-1999; 64 during 2001-2002) and axillary dissections started to decrease. A small group has had no axillary node biopsy or dissection, mainly patients over 70 years of age. Multimodality treatments increased over the 5-year period of our study with the use of postoperative radiotherapy increasing from 60% to 65% and chemotherapy from 36% to 55%.

CONCLUSIONS

The project has mapped treatment trends for breast cancer in our region and documented the implementation of new treatment methods as well as the increasing use of multidisciplinary management, multimodality treatment and the implementation of best practice guidelines.

Surgical trainees' attitudes to specialization in breast surgery

BACKGROUND

Subspecialization in general surgery is being encouraged by various surgical societies. The aim of this study was to view attitudes of Royal Australasian College of Surgeons (RACS) trainees to subspecialization in surgery, in particular, breast -surgery.

METHODS

A postal questionnaire survey of registered RACS basic and advanced surgical trainees was conducted in February 2002. Trainees were asked to nominate their preferred specialty and to indicate the level of support and interest for subspecialty training in breast surgery. Trainees indicating breast surgery as their preferred career choice were then asked to nominate their reasons for choosing breast surgery, preferred options for cross-specialty training and for vocation specifications such as a continuing 'on-call' responsibility.

RESULTS

Trainees returned 291 of 1049 (28%) completed questionnaires. One hundred and sixty-nine trainees felt that the concept of breast subspecialization in general surgery was reasonable (58%). For all respondents, the most popular specialty choices were plastic surgery (15.8%), orthopaedics (15.5%) and general surgery (15.4%). Breast surgery was chosen by 14 of 291 (4.8%) respondents as their first specialty preference and a further 25 respondents as their second specialty preference. Of 189 trainees who did not choose breast surgery as their preferred specialty, 45% stated repetitive stress, escalating litigation or demanding patients as deterrent factors. Only 36% of trainees interested in breast surgery were interested in undertaking after hours 'on-call' work as a consultant, although 36 of 39 (92%) were interested in other forms of general or subspecialty elective surgical operating (i.e., endocrine surgery, surgical oncology) after completion of their training. According to trainees with an interest in breast surgery, the two most important aspects requiring inclusion in the proposed provisional training program were breast reconstruction (38%) and breast screen assessment (34%).

CONCLUSION

Breast surgery is an unpopular subspecialty for RACS trainees. Breast surgery is likely to experience increasing -problems with recruitment unless the skill base is reviewed and revised in line with the aspirations and needs of today's trainees.
