Measurement that matters: A systematic review and modified Delphi of multidisciplinary colorectal cancer quality indicators.

AIM: To develop a priority set of quality indicators (QIs) for use by colorectal cancer (CRC) multidisciplinary teams (MDTs). METHODS: The review search strategy was executed in four databases from 2009-August 2019. Two reviewers screened abstracts/manuscripts. Candidate QIs and characteristics were extracted using a tailored abstraction tool and assessed for scientific soundness. To prioritize candidate indicators, a modified Delphi consensus process was conducted. Consensus was sought over two rounds; (1) multidisciplinary expert workshops to identify relevance to Australian CRC MDTs, and (2) an online survey to prioritize QIs by clinical importance. RESULTS: A total of 93 unique QIs were extracted from 118 studies and categorized into domains of care within the CRC patient pathway. Approximately half the QIs involved more than one discipline (52.7%). One-third of QIs related to surgery of primary CRC (31.2%). QIs on supportive care (6%) and neoadjuvant therapy (6%) were limited. In the Delphi Round 1, workshop participants (n = 12) assessed 93 QIs and produced consensus on retaining 49 QIs including six new QIs. In Round 2, survey participants (n = 44) rated QIs and prioritized a final 26 QIs across all domains of care and disciplines with a concordance level > 80%. Participants represented all MDT disciplines, predominantly surgical (32%), radiation (23%) and medical (20%) oncology, and nursing (18%), across six Australian states, with an even spread of experience level. CONCLUSION: This study identified a large number of existing CRC QIs and prioritized the most clinically relevant QIs for use by Australian MDTs to measure and monitor their performance.

Characteristics and post-metastasis survival of recurrent metastatic breast cancer over time - An Australian population-based record linkage study, 2001-2016.

AIM: To assess population-level characteristics and post-metastasis survival of people with recurrent metastatic breast cancer (rMBC) during a period when new publicly-subsidised adjuvant and metastatic systemic therapies became available. METHODS: Record linkage study of females in NSW Cancer Registry (NSWCR) diagnosed with non-metastatic breast cancer (BC) in 2001-2002 (C1) and 2006-2007 (C2). We identified first rMBC from NSWCR, administrative hospital records, dispensed medicines and radiotherapy services (2001-2016). We used death registrations to estimate cumulative incidence of BC death. RESULTS: The analysis included 2267 women with rMBC (C1:1210, C2:1057). Compared to C1, C2 had access to adjuvant HER2-targeted therapy and were more likely to have received adjuvant chemotherapy (C1:38%, C2:47%) and aromatase inhibitors (C1:52%, C2:73%, of those dispensed endocrine therapy). Five-year probability of BC death was 65% (95%CI:62-68%) in C1 and 63% (95%CI:60-66%) in C2. Regional disease (T4 or N + ) at initial BC diagnosis (C1:62%, C2:68%), and age ≥ 70 years at first metastasis (C1:27%, C2:31%) were more common in C2 and had poorer prognosis. Five-year probability of BC death was lower in C2 than C1 for treatment-defined HER2-positive BC (C1:72% 95%CI:63-79%; C2:52% 95%CI 45-60%) and those dispensed chemotherapy alone (C1:76% 95%CI:69-82, C2:67% 95%CI:59-74%, p = 0.01), but not treatment-defined hormone receptor-positive HER2-negative BC (C1:60% 95%CI 56-63%, C2:64% 95%CI 60-68%). CONCLUSIONS: Despite less favourable prognostic characteristics in C2, BC-related survival following rMBC was similar between the two cohorts; and improved for women with HER2-positive tumours. These findings support the real-world benefits of newer treatments for rMBC.

Decline in the Incidence of Distant Recurrence of Breast Cancer: A Population-Based Health Record Linkage Study, Australia 2001-2016.

BACKGROUND: We investigated differences in cumulative incidence of first distant recurrence (DR) following non-metastatic breast cancer over a time period when new adjuvant therapies became available in Australia. METHODS: We conducted a health record linkage study of females with localized (T1-3N0) or regional (T4 or N+) breast cancer in the New South Wales Cancer Registry in 2001 to 2002 and 2006 to 2007. We linked cancer registry records with administrative records from hospitals, dispensed medicines, radiotherapy services, and death registrations to estimate the 9-year cumulative incidence of DR and describe use of adjuvant treatment. RESULTS: The study included 13,170 women (2001-2002 n = 6,338, 2006-2007 n = 6,832). The 9-year cumulative incidence of DR was 3.6% [95% confidence interval (CI), 2.3%-4.9%] lower for 2006-2007 diagnoses (15.0%) than 2001-2002 (18.6%). Differences in the annual hazard of DR between cohorts were largest in year two. DR incidence declined for localized and regional disease. Decline was largest for ages <40 years (absolute difference, 14.4%; 95% CI, 8.3%-20.6%), whereas their use of adjuvant chemotherapy (2001-2002 49%, 2006-2007 75%) and HER2-targeted therapy (2001-2002 0%, 2006-2007 16%) increased. DR did not decline for ages ≥70 years (absolute difference, 0.9%; 95% CI, -3.6%-1.8%) who had low use of adjuvant chemotherapy and HER2-targeted therapy. CONCLUSIONS: This whole-of-population study suggests that DR incidence declined over time. Decline was largest for younger ages, coinciding with changes to adjuvant breast cancer therapy. IMPACT: Study findings support the need for trials addressing questions relevant to older people and cancer registry surveillance of DR to inform cancer control programs.

Long term risk of distant metastasis in women with non-metastatic breast cancer and survival after metastasis detection: a population-based linked health records study.

OBJECTIVES: To estimate the long term risk of distant metastases (DM) for women with initial diagnoses of non-metastatic breast cancer; to estimate breast cancer-specific and overall survival for women with DM. DESIGN: Population-based health record linkage study. SETTING, PARTICIPANTS: Women diagnosed with localised or regional primary breast cancer recorded in the NSW Cancer Registry, 2001-2002. MAJOR OUTCOME MEASURES: Time from breast cancer diagnosis to first DM, time from first DM to death from breast cancer. SECONDARY OUTCOME: time to death from any cause. RESULTS: 6338 women were diagnosed with non-metastatic breast cancer (localised, 3885; regional, 2453; median age, 59 years [IQR, 49-69 years]). DM were recorded (to 30 September 2016) for 1432 women (23%; median age, 62 years [IQR, 51-73 years]). The 14-year cumulative DM incidence was 22.2% (95% CI, 21.1-23.2%; localised disease: 14.3% [95% CI, 13.2-15.4%]; regional disease: 34.7% [95% CI, 32.8-36.6%]). Annual hazard of DM was highest during the second year after breast cancer diagnosis (localised disease: 2.8%; 95% CI, 2.3-3.3%; regional disease: 9.1%; 95% CI, 7.8-10.3%); from year five it was about 1% for those with localised disease, from year seven about 2% for women with regional disease at diagnosis. Five years after diagnosis, the 5-year conditional probability of DM was 4.4% (95% CI, 3.7-5.1%) for women with localised and 10.4% (95% CI, 9.1-12.0%) for those with regional disease at diagnosis. Median breast cancer-specific survival from first DM record date was 28 months (95% CI, 25-31 months); the annual hazard of breast cancer death after the first DM record declined from 36% (95% CI, 33-40%) during the first year to 14% (95% CI, 11-18%) during the fourth year since detection. CONCLUSIONS: DM risk declines with time from diagnosis of non-metastatic breast cancer, and the annual risk of dying from breast cancer declines with time from initial DM detection. These findings can be used to inform patients at follow-up about changes in risk over time since diagnosis and for planning health services.

Quality indicators for radiation oncology.

Quality Indicators, based on clinical practice guidelines, have been used in medicine and within oncology to measure quality of care for over twenty years. However, radiation oncology quality indicators are sparse. This article describes the background to the development of current national and international, general and tumour site-specific radiation oncology quality indicators in use. We explore challenges and opportunities to expand their routine prospective collection and feedback to help drive improvements in the quality of care received by people undergoing radiation therapy.

A narrative synthesis of the quality of cancer care and development of an integrated conceptual framework.

The general paradigms that exist to guide measures in quality of care do not sufficiently deal with the changing needs of cancer management. The aim of this study was to review the literature regarding the quality of cancer care and develop a conceptual framework relevant to current practice. A textual narrative review of the literature was conducted by searching electronic databases from the last 10 years. Articles were then screened and included if they were both relevant to the management of cancer and standards in quality of care. Thematic analysis of the included articles was performed. Eighty-three articles were included and 12 domains identified and integrated with current models to develop a conceptual framework. These included: healthcare delivery system; timeliness; access; appropriateness of care; multidisciplinary and coordinated care; patient experience; technical aspects; safety; patient-centred outcomes; disease-specific outcomes; innovation and improvement and value. We propose a conceptual framework for the quality of cancer care based on relevant and current oncology practice. This presents a more practical and comprehensive approach than general models, and can be used by healthcare providers, managers and policy makers to guide and identify the need for metrics for quality improvements.

Assessing guideline adherence and patient outcomes in cervical cancer.

AIM: To investigate adherence to clinical practice guidelines (CPGs) in cervical cancer and the correlation with clinical outcomes. METHODS: A retrospective analysis was conducted using patient information from a population-based cancer registry (2005-2011, n = 208). Compliance to 10 widely accepted CPGs was assessed. Univariate and multivariate analyses were performed to assess sociodemographic factors associated with CPG adherence. Multivariate Cox regression was performed to assess the relationship between CPG adherence and 5-year survival. RESULTS: Adherence to individual CPGs ranged from 47% to 100%. Compliance to all applicable CPGs was seen in 54% (n = 72) of patients, 62% of stage I and II patients and 22% of stage III and IV patients. Poorest adherence was seen with those with locally advanced disease receiving chemoradiotherapy. Patients who lived within 5 km of the treatment facility were more likely to be compliant. No difference was found for either age, country of birth or socioeconomic status group. Five-year survival was greater for stage I and II patients who received guideline adherent care (93.7% vs 69.7%, P = 0.002), and they had a significant lower risk of death on multivariate analysis (HR = 0.22, P = 0.015). There was no significant difference for those with stage III or IV disease. CONCLUSIONS: In this study, CPG adherence is variable between treatment modalities and only half complied to all applicable CPGs. There was better adherence in those with early-stage disease and this was associated with improved patient outcomes. CPG adherence may be a useful surrogate for quality of care.
