Health center nurse knowledge |
Nurses' knowledge will be assessed through written tests administered immediately before and immediately after trainings, and delayed post-tests administered 3 to 6 months after training. The investigators will use an adapted instrument that incorporates the Breast Cancer Knowledge Test and other surveys to assess clinician knowledge about breast cancer risk, signs and symptoms, and treatability. Questions were developed through review of existing instruments used in the United States, Mexico, the United Kingdom, and Nigeria, and expert input, feedback from clinical colleagues in Rwanda, and pilot testing with Rwandan hospital-based nurses. We will assess each nurse's overall test score as the total percentage of questions correct and assess scores within specific knowledge domains. The more questions answered correctly and the higher the score, the better the outcome (the score represents the percent of questions answered correctly). |

Community health worker knowledge |
CHWs' knowledge will be assessed through written tests administered immediately before and immediately after trainings, and delayed post-tests administered 3 to 6 months after training. The investigators will use an adapted instrument that incorporates the Breast Cancer Knowledge Test and other surveys to assess clinician knowledge about breast cancer risk, signs and symptoms, and treatability. Questions were developed through review of existing instruments used in the United States, Mexico, the United Kingdom, and Nigeria, and expert input, feedback from clinical colleagues in Rwanda, and pilot testing with Rwandan hospital-based nurses. We will assess each CHW's overall test score as the total percentage of questions correct and assess scores within specific knowledge domains. The more questions answered correctly and the higher the score, the better the outcome (the score represents the percent of questions answered correctly). |

Health center nurse clinical skills |
Nurses' performance scores on clinical breast exam checklists that assess completion of the steps required for high-quality clinical breast exam and are based on other published checklists adapted to the rural Rwandan setting. CBE materials were based on CBE guidelines and published and unpublished curricula adapted to our setting. During her regular health center visits, the breast health mentor will assess nurses' clinical skills in their clinics by using a checklist that includes the same questions as the pre- and post-test assessment form. When possible, the mentor will assess individual nurses by using the same checklist two or more times during a given clinical session, including one at the beginning of a session. We will analyze checklists completed between May 2015 and September 2016. The more actions performed correctly and the higher the score, the better the outcome (the score represents the percent of actions performed correctly). |

Secondary |
System delays |
Among patients referred from intervention versus control health centers to the hospital for breast concerns, length of time experienced between first presentation at a health center and first presentation at the hospital. |

Secondary |
Breast cancer detection rate |
Among patients referred to the hospital from intervention health centers, proportion diagnosed with breast cancer compared to the proportion among those referred from control health centers, and the proportion from intervention health centers before the trainings. |

Secondary |
Breast cancer stage |
Among patients diagnosed with breast cancer from intervention health centers, the AJCC versus 7 clinical breast cancer stage documented in hospital medical records. The investigators will compare the proportion of patients presenting with Stage I or II stage disease to the proportion with stage I or II disease among those referred from control health centers, and those from intervention health centers before the trainings. |
