Using Patient Navigation to Reduce Time to Diagnosis of Breast Cancer in Uganda

PURPOSE

The Ugandan Ministry of Health adopted BI-RADS as standard of care in 2016. The authors performed a medical audit of breast ultrasound practices at four tertiary-level hospitals to assess interpretive performance. The authors also determined the effect of a low-cost navigation program linking breast imaging and pathology on the percentage of patients completing diagnostic care.

METHODS

The authors retrieved 966 consecutive diagnostic breast ultrasound reports, with complete data, for studies performed on women aged >18 years presenting with symptoms of breast cancer between 2018 and 2020 from participating hospitals. Ultrasound results were linked to tumor registries and patient follow-up. A medical audit was performed according to the ACR's BI-RADS Atlas, fifth edition, and results were compared with those of a prior audit performed in 2013. At Mulago Hospital, an intervention was piloted on the basis of patient navigation, cost sharing, and same-day imaging, tissue sampling, and pathology.

RESULTS

In total, 888 breast ultrasound examinations (91.9%) were eligible for inclusion. Compared with 2013, the postintervention cancer detection rate increased from 38 to 148.7 cancers per 1,000 examinations, positive predictive value 2 from 29.6% to 48.9%, and positive predictive value 3 from 62.7% to 79.9%. Specificity decreased from 90.5% to 87.7% and sensitivity from 92.3% to 81.1%. The mean time from tissue sampling to receipt of a diagnosis decreased from 60 to 7 days. The intervention increased the percentage of patients completing diagnostic care from 0% to 100%.

CONCLUSIONS

Efforts to establish a culture of continuous quality improvement in breast ultrasound require robust data collection that links imaging results to pathology and patient follow-up. Interpretive performance met BI-RADS benchmarks for palpable masses, except sensitivity. This resource-appropriate strategy linking imaging, tissue sampling, and pathology interpretation decreased time to diagnosis and rates of loss to follow-up and improved the precision of the audit.

Breast cancer early detection and diagnostic capacity in Uganda

BACKGROUND

Greater than 80% of women presenting for breast cancer treatment in Uganda have late-stage disease, which is attributable to a dysfunctional referral system and a lack of recognition of the early signs and symptoms among primary health care providers, and compounded by the poor infrastructure and inadequate human capacity. Improving the breast health care system requires a systemic approach beginning with situational analysis to identify systematic gaps that prevent sustainable improvements in outcome.

METHODS

The authors performed a situational analysis of the breast health care system using methods developed by the Breast Health Global Initiative. Based on their findings, they developed a series of recommendations for strengthening the health system for the early diagnosis of breast cancer based on clinical detection, referral, tissue sampling, and diagnosis.

RESULTS

Deficits in the recognition of breast cancer signs and symptoms, the underuse of clinical breast examination as a diagnostic and/or screening tool, the centralization of diagnostic tests (radiology and pathology), reliance on excisional biopsies rather than needle biopsies, and a lack of trained professionals and knowledge of the referral system all contribute to significant health system delays.

CONCLUSIONS

To strengthen referral networks and improve the early diagnosis of breast cancer in Uganda, national referral hospitals should provide educational programs to primary health care providers in community health centers (CHCs), at which the majority of women first present with symptoms. At secondary district-level facilities in which imaging and tissue sampling can be performed, the capacity for diagnostic testing could be increased through task shifting of basic interpretation (abnormal vs normal) from specialists to nonspecialists using networking technology to facilitate remote oversight from specialists at the national referral hospitals.

Case Report: Biloma gastrostomy after failed sonogram-guided percutaneous aspiration, pigtail catheter insertion and surgical drainage

Bilomas are rare abnormal extrabiliary accumulation of bile.  This can be either intrahepatic or extrahepatic following traumatic or spontaneous rupture of the biliary tree. The commonest causes of biloma are surgery, percutaneous transhepatic cholangiography, percutaneous transhepatic biliary drainage, transcatheter arterial embolization and abdominal trauma. We report here a 15 year old patient whom we followed for over 10 years. His chief complaints were right hypochondriac pain, loss of appetite and vomiting. Initial clinical presentation, sonographic as well as laboratory findings suggested a liver abscess, which was drained, but the definitive diagnosis of biloma was entertained after sonographically guided percutaneous aspirations and percutaneous transhepatic cholangiography 7 years later. We also discuss the role of imaging and surgical challenges encountered that culminated into bilomo-gastrostomy. The patient is now enjoying a peaceful life.

The impact of attachment and depression symptoms on multiple risk behaviors in post-war adolescents in northern Uganda

BACKGROUND

We have previously shown that depression symptoms are associated with multiple risk behaviors and that parental attachments are protective against depression symptoms in post-war adolescents. Accumulating literature indicates that low levels of attachment may sensitize individuals to increased multiple risk behaviors when depression symptoms exist. This investigation examined the interactive effects of attachment and depression symptoms on multiple risk behavior.

METHODS

We conducted hierarchical logistic regression analyses to examine the impact of attachment and depression symptoms on multiple risk behavior in our post-war sample of 551 adolescents in Gulu district.

RESULTS

Analyses revealed interactive effects for only maternal attachment-by-depression interaction. Interestingly, high levels of maternal attachment exacerbated the relationship between depression symptoms and multiple risk behaviors while low levels of maternal attachment attenuated this relationship.

LIMITATIONS

It is possible that this analysis could be biased by a common underlying factor that influences self-reporting and therefore is correlated with each of self-reported attachment security, depressive symptoms, and multiple risk behaviors.

CONCLUSIONS

These findings suggest that maternal attachment serves as a protective factor at low levels while serving as an additional risk factor at high levels. Findings support and expand current knowledge about the roles that attachment and depression symptoms play in the development of multiple risk behaviors and suggest a more complex etiology for post-war adolescents.

Breast cancer detection using sonography in women with mammographically dense breasts

Background

Mammography, the gold standard for breast cancer screening misses some cancers, especially in women with dense breasts. Breast ultrasonography as a supplementary imaging tool for further evaluation of symptomatic women with mammographically dense breasts may improve the detection of mass lesions otherwise missed at mammography.

The purpose of this study was to determine the incremental breast cancer detection rate using US scanning in symptomatic women with mammographically dense breasts in a resource poor environment.

Methods

A cross sectional descriptive study. Women referred for mammography underwent bilateral breast ultrasound, and mammography for symptom evaluation. The lesions seen by both modalities were described using sonographic BI-RADS lexicon and categorized. Ultrasound guided core biopsies were performed. IRB approval was obtained and all participants provided informed written consent.

Results

In total 148 women with mammographically dense breasts were recruited over six months. The prevalence of breast cancer in symptomatic women with mammographically dense breasts was 22/148 (15%). Mammography detected 16/22 (73%) of these cases and missed 6/22 (27%). The six breast cancer cases missed were correctly diagnosed on breast ultrasonography. Sonographic features typical of breast malignancy were irregular shape, non-parallel orientation, non circumscribed margin, echogenic halo, and increased lesion vascularity (p values < 0.005). Typical sonofeatures of benign mass lesions were: oval shape, parallel orientation and circumscribed margin (p values <0.005).

Conclusion

Breast ultrasound scan as a supplementary imaging tool detected 27% more malignant mass lesions otherwise missed by mammography among these symptomatic women with mammographically dense breasts. We recommend that ultra sound scanning in routine evaluation of symptomatic women with mammographically dense breasts.

Neuropsychiatric perspectives on nodding syndrome in northern Uganda: a case series study and a review of the literature

BACKGROUND

Nodding Syndrome (NS), previously called Nodding Disease, is a chronic and debilitating illness affecting thousands of children aged 3-18 years in post-conflict Northern Uganda and South Sudan. Characterised by malnutrition, stunted growth, mental retardation and seizures, some researchers have designated it as epilepsy. With reports appearing in Northern Uganda in1997, NS reached epidemic proportions around 2000-2003 when people were moved into Internally Displaced People's (IDP) camps. Investigations for infections (onchocerciasis) and toxins have been inconclusive as to cause, treatment or outcome. No study has addressed the possible relationship of NS to childhood war-trauma experiences.

OBJECTIVE

To explore a possible relationship of exposure to prolonged war-trauma and the emergence of epidemic NS in Northern Uganda.

METHOD

This study was a case-series descriptive psychiatric naturalistic field observations of NS cases from homesteads in Northern Uganda and psychiatric investigations and treatment of NS cases referred to Mulago National Referral and Teaching Hospital.

RESULTS

Detailed Psychiatric clinical evaluations and field observations revealed that NS children had been exposed to severe war-related psychological and physical trauma as well as non-specific CNS insults including untreated CNS infections/infestations and malnutrition possibly causing seizures. Many children suffered post-traumatic stress disorder (PTSD) and depression.

CONCLUSION

NS could present as an association of childhood complex PTSD, (called Developmental Trauma Disorder), occurring in the chronically war-traumatised children of Northern Uganda, complicated by severe prolonged depression with its characteristic symptoms of psychomotor retardation, anxiety, anhedonia and anorexia. This, coupled with food shortages, resulted in malnutrition, wasting and stunted growth with severe avitaminoses. Many children had seizures. All this calls for multi-disciplinary treatment approaches.

Psychiatric disorders among war-abducted and non-abducted adolescents in Gulu district, Uganda: a comparative study

OBJECTIVE

We aimed to assess the nature and patterns of psychiatric disorders among adolescents who had been war-abducted in the war in northern Uganda, compared to non-abducted adolescents living in Gulu district, Uganda.

METHOD

A cros sectional study that used an unmatched case-control design compared 82 abducted and 71 non-abducted adolescents for scores on measures of psychological distress and for selected psychiatric diagnoses using the Strength and Difficulties Questionnaire (SDQ) and the Mini International Neural-Psychiatric Interview for Children and Adolescents English version 2.0 (M.I.N.I-KID).

RESULTS

More than 90% of adolescents reported exposure to severe trauma, either through direct or indirect experiences. Significantly more war abducted adolescents reported PTSD (26.8%v.12.7%) (p=0.03) major depression (19.5%v.4.2%) (p=0.004), and generalised anxiety disorder (13.4v.4.2%) (p=0.049) than non abducted adolescents. By contrast, non-abducted adolescents reported more past suicidality (p=0.004, chi(2)=8.2) than adolescents who were abducted. However, despite high rates of psychiatric disorder, these adolescents had good psychosocial adjustment.

CONCLUSION

Adolescents in war affected areas whether warabducted or not have varied and clinically significant emotional responses to different kinds of traumatic exposure. In a war-affected area, the development of a sustainable service for adolescents that tries to address the full range of mental health problems may be more appropriate than a psychological trauma service that focuses on one diagnosis.
