“…Data from ambulatory care centers have been found to be less accurate than hospital-based care. 56 A study comparing the completeness of hospital medical records with records from outpatient treatment facilities is warranted, but unfortunately is well beyond the scope of the present investigation.…”

BACKGROUND: Incidence and mortality of breast cancer vary according to demographic factors such as age, race/ ethnicity, socioeconomic status (SES), and geographic region. This study assesses the variation of these factors in the use of adjuvant radiation therapy (RT) after breast-conserving surgery (BCS) among 8 regions of California. METHODS: The authors identified 85,574 cases of first primary female invasive breast cancer with complete data diagnosed between January 1, 2000 and December 31, 2007. Logistic regression was used to determine the association between race/ethnicity, age, SES, and receipt of RT after BCS within each of the regions of California. Odds ratios (ORs) and 95% confidence intervals (CIs) were computed. RESULTS: Age was a significant predictor of receipt of RT after BCS in all regions. In Los Angeles (LA), lower SES was associated with decreasing odds of RT. Racial disparities were evident only in LA, where black (OR, 0.85; 95% CI, 0.74-0.97) and Hispanic (OR, 0.86; 95% CI, 0.78-0.96) women were about 15% less likely to receive RT than white women. CONCLUSIONS: Racial disparities in the receipt of RT after BCS exist only in LA, where African American and Hispanic women are less likely to receive this form of adjuvant treatment. Lower SES was also associated with a reduced likelihood of receipt of RT in LA. Women age 70 years and older are less likely to receive RT after BCS in all regions of California.

“…After summarization, 238 and 205 cases revealed to have the inclusion criteria of the study in BCPC and HBCR, respectively. It should be noted that the data elements of the summarization instrument were obtained from American Joint Commission on Cancer (AJCC) (Edge and Compton, 2010), Charlson index (Charlson, 1987), similar studies (Malin et al, 2002;Moher et al, 2004), national standards, and the experts' opinions. Moreover, the reliability of the summarization instrument was confirmed by a number of experts.…”

“…Moreover, investors, consumers, and providers are highly interested in measuring the quality of cancer care and emphasize obtaining high-quality information (Pearson et al, 2002). Care quality measurement is a mechanism which quantifies the quality of a dimension of care by comparing the services provided for the patients with the standard criteria (Malin et al, 2002;Moher et al, 2004). The present study has focused on the process of care quality.…”

“…In general, the data provide the opportunity for measuring the care quality (Moher et al, 2004) evaluating the quality of cancer care are medical records and hospital cancer registrations (Coory, 2009). Overall, in order for the data resources to accurately assess the quality of care, reliable data on the intended care must be available (Malin et al, 2002).…”

“…In fact, the best way for data validation is comparing the registered data with the main source (Malin et al, 2002;Ferlay, 2005) and data validity can be used in case the main source is the gold standard. This is not usually possible in reality and, as a result, data agreement should be utilized (Guanmin, 2009).…”

Objectives: To investigate data agreement of cancer registries and medical records as well as the quality of care and assess their relationship in a 5-year period from 2006 to 2011. Methods: The present cross-sectional, descriptive-analytical study was conducted on 443 cases summarized through census and using a checklist. Data agreement of Nemazi hospital-based cancer registry and the breast cancer prevention center was analyzed according to their corresponding medical records through adjusted and unadjusted Kappa. The process of care quality was also computed and the relationship with data agreement was investigated through chi-square test. Results: Agreement of surgery, radiotherapy, and chemotherapy data between Nemazi hospital-based cancer registry and medical records was 62.9%, 78.5%, and 81%, respectively, while the figures were 93.2%, 87.9%, and 90.8%, respectively, between breast cancer prevention center and medical records. Moreover, quality of mastectomy, lumpectomy, radiotherapy, and chemotherapy services assessed in Nemazi hospital-based cancer registry was 12.6%, 21.2%, 35.2%, and 15.1% different from the corresponding medical records. On the other hand, 7.4%, 1.4%, 22.5%, and 9.6% differences were observed between the quality of the above-mentioned services assessed in the breast cancer prevention center and the corresponding medical records. A significant relationship was found between data agreement and quality assessment. Conclusion: Although the results showed good data agreement, more agreement regarding the cancer stage data elements and the type of the received treatment is required to better assess cancer care quality. Therefore, more structured medical records and stronger cancer registry systems are recommended.Keywords: Cancer data agreement -care quality measurement -breast cancer care -process of care -Iran

Validity of Cancer Registry Data for Measuring the Quality of Breast Cancer Care

Abstract: Cancer registry data for quality measurement may not be valid for all care settings, but registries could provide the infrastructure for collecting data on the quality of cancer care. We urge that funding be increased to augment data collection by cancer registries.
