Factors associated with completeness in documentation of diagnostic work-up and treatment in patients with breast cancer in Sudan

Purpose

This study evaluates the relationship between geography and ethnicity on the completeness of documentation of diagnostic work-up and treatment modalities in Sudan for patients with breast cancer.

Methods

This retrospective study used data abstracted from patients with breast cancer receiving cancer care at Sudan's largest cancer centre (Radiation and Isotopes Center Khartoum) in 2017. Patient demographic and clinical characteristics were abstracted from paper medical records. Odds ratios and 95% confidence intervals were estimated to evaluate complete diagnostic work-up on ethnic group, origin and residence using binomial logistic regression models.

Results

Of 237 patients, the median age was 52 (interquartile range 43-61). Most often patients identified as Arab (68%), originated from Central, Northeastern and Khartoum regions (all 28%) and lived in the Khartoum region (52%). Overall, 49% had incomplete diagnostic work-up, with modest differences by ethnicity and geography. In adjusted analyses, non-statistical differences were found between the ethnic group, geographic origin and residence and having complete diagnostic work-up. For treatment modality, significant differences were observed between receptor status and receiving hormone therapy (p = 0.004). Only 28% of patients with HR+ breast cancer received hormonal therapy. For those with HR- or undocumented breast cancer subtype, 36% and 17% received hormone therapy, respectively.

Conclusion

Approximately half of Sudanese patients with breast cancer had incomplete diagnostic work-up, irrespective of ethnicity and geography. Moreover, a high proportion of patients received inappropriate treatment. This underlines a considerable systems-based quality gap in care delivery, demanding efforts to improve diagnostic work-up for all patients with breast cancer in Sudan.

What’s missing? Diagnostic workup for breast cancer in Sudan

Background: In Sudan, healthcare access may limit diagnostic workup for breast cancer. This study evaluates the relationship between geography and ethnicity and completeness of documentation of diagnostic workup (staging and receptor testing) in Sudan. Methods: This retrospective study used data abstracted from patients with breast cancer receiving cancer care at Sudan’s largest cancer center (Radiation and Isotopes Center Khartoum [RICK]) in 2017. The patient’s age at diagnosis, sex, breast cancer stage, ethnic subgroup (further categorized as Arab and non-Arab), regions of origin and residence (Central, Northeastern, Western, and Khartoum [where RICK is located]), and receptor status from pathology reports were abstracted from paper medical records. Complete diagnostic workup was defined as having both receptor testing and staging. Descriptive statistics were calculated using frequencies and percentages for categorical variables and median and interquartile range (IQR) for continuous variables. Odds ratios (OR) and 95% confidence intervals (CI) were estimated to evaluate complete diagnostic workup on ethnic group, origin, and residence using binomial logistic regression models (excluding non-Sudanese patients and those with missing demographics). Results: Of 240 patients included, 237 were female, median age was 53 (IQR 43-62). Most often patients were Arab (68%), originated from Northeastern and Khartoum regions (both 28%) and lived in the Khartoum region (53%). Overall, 49% patients were missing receptor testing and/or staging, with modest differences by geographic region and ethnicity (Table). In adjusted analyses, non-Arab patients had similar odds of having complete diagnostic workup when compared to Arab patients (OR 1.22; 95% CI 0.70-2.10). Patients originating from and residing in regions outside the Khartoum region had similar odds of complete diagnostic workup when compared to patients originating from and residing in the Khartoum region. Conclusions: Almost half of breast cancer patients had incomplete diagnostic workup, regardless of region of origin, region of residence, and ethnic group. This highlights a substantial systems-based quality gap in care delivery, warranting efforts to improve completeness in diagnostic workup for all patients with breast cancer in Sudan.[Table: see text]
