Breast Cancer Guidelines in Canada: A Review of Development and Implementation

How do surgeons decide to refer patients for adjuvant cancer treatment? Protocol for a qualitative study

BACKGROUND

Non-small cell lung cancer, breast cancer, and colorectal cancer are commonly diagnosed cancers in Canada. Patients diagnosed with early-stage non-small cell lung, breast, or colorectal cancer represent potentially curable populations. For these patients, surgery is the primary mode of treatment, with (neo)adjuvant therapies (e.g., chemotherapy, radiotherapy) recommended according to disease stage. Data from our research in Nova Scotia, as well as others', demonstrate that a substantial proportion of non-small cell lung cancer and colorectal cancer patients, for whom practice guidelines recommend (neo)adjuvant therapy, are not referred for an oncologist consultation. Conversely, surveillance data and clinical experience suggest that breast cancer patients have much higher referral rates. Since surgery is the primary treatment, the surgeon plays a major role in referring patients to oncologists. Thus, an improved understanding of how surgeons make decisions related to oncology services is important to developing strategies to optimize referral rates. Few studies have examined decision making for (neo)adjuvant therapy from the perspective of the cancer surgeon. This study will use qualitative methods to examine decision-making processes related to referral to oncology services for individuals diagnosed with potentially curable non-small cell lung, breast, or colorectal cancer.

METHODS

A qualitative study will be conducted, guided by the principles of grounded theory. The study design is informed by our ongoing research, as well as a model of access to health services. The method of data collection will be in-depth, semi structured interviews. We will attempt to recruit all lung, breast, and/or colorectal cancer surgeons in Nova Scotia (n ≈ 42), with the aim of interviewing a minimum of 34 surgeons. Interviews will be audiotaped and transcribed verbatim. Data will be collected and analyzed concurrently, with two investigators independently coding and analyzing the data. Analysis will involve an inductive, grounded approach using constant comparative analysis.

DISCUSSION

The primary outcomes will be (1) identification of the patient, surgeon, institutional, and health-system factors that influence surgeons' decisions to refer non-small cell lung, breast, and colorectal cancer patients to oncology services when consideration for (neo)adjuvant therapy is recommended and (2) identification of potential strategies that could optimize referral to oncology for appropriate individuals.

Factors related to the implementation and use of an innovation in cancer surgery

OBJECTIVE

Nationally, efforts to implement an innovation in cancer surgery-a Web-based synoptic reporting tool-are ongoing in five provinces. The objective of the present study was to identify the key multilevel factors influencing implementation and early use of this innovation for breast and colorectal cancer surgery at two academic hospitals in Halifax, Nova Scotia.

METHODS

We used case-study methodology to examine the implementation of surgical synoptic reporting. Methods included semi-structured interviews with key informants (surgeons, implementation team members, and report end users; n = 9), nonparticipant observation, and document analysis. A thematic analysis was conducted separately for each method, followed by explanation-building to integrate the evidence and to identify the key multilevel factors influencing implementation. An audit was performed to determine use.

RESULTS

Key factors influencing implementation were these: Innovation-values fitFlexibility with the innovation and implementationThe innovation is not flawlessStrengthening the climate for implementationResource needs and availabilityPartner engagementSurgeon champions and involvementIn a 6-month period after implementation, 91.2% and 58.0% respectively of eligible breast and colorectal cancer surgeries were reported using the new tool.

CONCLUSIONS

An improved understanding of the multilevel factors influencing the implementation of innovations is critical to planning effective change interventions in health care. Further study is needed to explore differences in the use of the innovation between breast and colorectal cancer surgeons. Findings will inform the study of additional cases of synoptic reporting implementation, enabling cross-case analyses and identification of higher-level themes that may be applied in similar settings or contexts.
