Development and Update of Guideline-based Quality Indicators in Lung Cancer.

BACKGROUND: In 2022, an update of the German lung cancer guideline, first published in 2010 and revised in 2018, was released. This article aims to show the process of updating, developing, and implementing guideline-based quality indicators (QI) into the certification system for lung cancer centers (LCC). METHODS: A multidisciplinary and interprofessional working group revised the guideline QIs from 2018 using the strong recommendations of the guideline update, a systematic review for QIs, and the results of the implemented QIs from LCC. RESULTS: For 4 out of 8 indicators from the 2018 guideline, the LCC showed an improved implementation of the requirements in the last 3 years (2018-2020). For 3 indicators, the median of the results was constant at a very high level (≥96% or 100%). Only the "adjuvant cisplatin-based chemotherapy" indicator showed declining values between 2018 and 2020. The target values and plausibility limits were well achieved by LCC. After updating the guideline, one QI from 2018 was not included in the new QI set due to the small denominator population. Based on the new strong recommendations, 8 new QIs were defined. From the QI set of the guideline update, 13 of 15 indicators (7 since 2018 and 6 from 2022 on) were adopted into the certification program. CONCLUSIONS: The guideline recommendations are implemented by LCC at a high level. The process presented confirms the successful implementation of the so-called quality cycle in oncology. The QIs developed by the German Guideline Program in Oncology (GGPO) are adopted by the certification program. The implementation of the QI is measured in LCC, evaluated by the German Cancer Society (DKG), and reflected back to the GGPO. The "real world" data have led to the deletion of one QI and show a high implementation of most QIs in LCC.

Quality Measurement for Soft Tissue Sarcomas in Germany: First Results of the Certified Sarcoma Centres.

INTRODUCTION: Soft tissue sarcomas (STSs) are rare diseases. A high level of standardization and centralization was lacking in Germany until 2018. METHODS: By developing an evidence-based guideline and a certification system for sarcoma centres, foundations for structured, guideline-based, and centralized sarcoma care were defined. First results of the certified sarcoma centres are presented. RESULTS: The first 3 years of data collection show good results for case volume, presentation rates in pretherapeutic and postoperative tumour boards, psycho-oncological counselling, and study rates. However, other indicators (e.g., preoperative or postoperative radiotherapy for operated high-risk STS without GIST, counselling rates social services) still have potential for improvement. Based on these results, the set of indicators could be further improved. CONCLUSIONS: A sarcoma-specific quality assurance scheme that includes guideline-derived quality indicators was developed. In future, a broader database will allow further insights into sarcoma care in Germany.

Guideline-Based Quality Indicators for Kidney and Bladder Cancer in Germany: Development and Implementation.

INTRODUCTION: As part of the development of the evidence-based (S3) clinical practice guidelines for kidney and bladder cancer by the German Guideline Program in Oncology, quality indicators (QIs) were defined to measure the quality of care. Based on these guidelines and QIs, the German Cancer Society (DKG) developed two new certification systems. The aim of this article is to show the process of development and implementation of QIs in certified cancer centres. METHODS: Based on strong recommendations of each guideline and an additional systematic literature review for national and international QIs, two sets of QIs were derived in a multistep standardized approach. These QIs were implemented in the centres in certification data sheets to measure their outcomes. First results of treatment years 2018 and 2019 are available. RESULTS: The final sets include 9 QIs for kidney cancer and 12 QIs for bladder cancer. Two-thirds of the QIs were transferred to the data sheets. In 2018 and 2019, the results of all but one QI are within the plausibility limits. From 2020 on, they are replaced by stricter target values that will challenge centres to improve their outcomes. CONCLUSIONS: Guideline-derived QIs make relevant aspects of patient care measurable and consequently improvable. The first QI results are encouraging. However, the DKG certification system and the methods of measuring quality are under ongoing development. Systematic QI implementation and evaluation may help to generate broader databases and thus expand knowledge.
