Cervical Cancer Screening in Cameroon: Interobserver Agreement on the Interpretation of Digital Cervicography Results.

OBJECTIVE: The World Health Organization recommends visual inspection with acetic acid (VIA) for cervical cancer screening in resource-limited settings. In Cameroon, we use digital cervicography (DC) to capture images of the cervix after VIA. This study evaluated interobserver agreement of DC results, compared DC with histopathologic results, and examined interobserver agreement among screening methods. METHOD: Three observers, blinded to each other's interpretations, evaluated 540 DC photographs as follows: (1) negative/positive for acetowhite lesions or cancer and (2) assigned a presumptive diagnosis of histopathologic lesion grade in the 91 cases that had a histopathologic diagnosis. Observer A was the actual screening nurse; B, a reproductive health nurse; C, a gynecologic oncologist; and D, the histopathologic diagnosis. We compared inter-rater agreement of DC impressions among observers A, B, and C, and with D, with Cohen kappas. RESULTS: For interpretations of DC, (negative/positive) strengths of agreement of paired observers were the following: A/B, moderate [K, 0.54; 95% confidence interval (CI), 0.47-0.61], A/C, fair (K, 0.37; 95% CI, 0.29-0.44), and B/C, moderate (K, 0.45; 95% CI, 0.37-0.53). For presumptive pathologic grading, strengths of agreement for weighted Ks were as follows: A/B, moderate (K, 0.42; 95% CI, 0.28-0.56); A/C, fair (K, 0.33; 95% CI, 0.20-0.46); B/C, fair (K, 0.54; 95% CI, 0.40-0.67); A/D, moderate (K, 0.59; 95% CI, 0.45-0.74); B/D, moderate (K, 0.58; 95% CI, 0.46-0.70); and C/D, moderate (K, 0.50; 95% CI, 0.37-0.63). CONCLUSIONS: Interobserver agreement of DC interpretations was mostly moderate among the 3 observers, between them and histopathology, and comparable to that of other visual-based screening methods, i.e., VIA, cytology, or colposcopy.

Assisted HIV partner notification services in resource-limited settings: experiences and achievements from Cameroon.

INTRODUCTION: In 2007, the Cameroon Baptist Convention Health Services (CBCHS) initiated an assisted partner notification services (aPNS) public health programme to increase HIV case identification and reduce HIV incidence in the most affected regions of Cameroon. We describe large-scale implementation of aPNS and overall programmatic achievements in a resource-limited setting through 2015. METHODS: CBCHS trained health advisors (HAs) from 16 CBCHS facilities and 22 non-CBCHS facilities to integrate aPNS into their existing jobs in five of the ten Cameroon regions. HAs recorded basic demographic, clinical and risk factor information from consenting index persons (IPs) and similar information about their sexual partners'/contact persons (CPs) on interview records and aPNS registers. These data were entered into an Epi-Info database. HAs provided pre-test counselling to CPs and offered them HIV testing in their home or other location. HAs educated IPs and CPs on HIV prevention and risk reduction, and referred IPs and HIV positive CPs to HIV care and treatment centres. Starting in 2014, HAs re-interviewed IPs 30 days after their initial aPNS interview to ascertain instances of social harms following partner notification. Continuous predictor and outcome variables were summarized using median and interquartile range, while categorical variables were summarized using percentages from 2007 to 2015. RESULTS: A total of 18,730 IPs (71% women) received aPNS over nine years. IPs identified 21,057 CPs (67% men) (mean CP/IP 1.12), of whom 12,867 (61.1%) were notified of their exposure to HIV. A total of 9202 (71.5% of notified CPs) tested for HIV, 4764 (51.8%) of whom tested HIV positive (number of IPs needed to interview = 3.9); 3112 (65.3%) HIV-positive partners were referred to HIV care and treatment centres. Of the 976 IPs receiving aPNS in 2014 to 2015, for whom follow-up data were available, 11 (1.1%) reported physical intimate partner violence from CPs. Thus, 44.3% of 1224 CPs were notified through provider referral. Of the 784 CPs who tested for HIV, 157 were newly diagnosed and the overall HIV prevalence was 41.6% (326/784). CONCLUSIONS: aPNS is feasible, can be brought to scale, yields a high level of case identification, and is infrequently associated with social harms and intimate partner violence.

Measuring the quality of diabetes care in urban and rural Indian health programs.

OBJECTIVE: The purpose of this study was to compare the quality of diabetes care provided to American Indians/Alaska Natives (AI/AN) by urban and rural Indian health programs. DESIGN: Medical record review data collected by the Indian Health Service as part of the Diabetes Care and Outcomes Audit in 2002. SETTING: Seventeen urban Indian health clinics and 225 rural Indian health programs. PATIENTS: All urban AI/AN patients (n = 710) and random sample records of rural AI/AN patients (n=1420). MAIN OUTCOMES MEASURES: Adherence to guidelines for process measures and intermediate outcomes of diabetes care. RESULTS: Compared to the rural sample, urban patients were more likely to have received diabetes education during the prior year (P < or = .05). Annual dental examinations were less common among urban patients than rural patients (19% vs 41%, P < or = .001). Completion of laboratory testing and immunizations were similar in both groups. Adjusted mean levels for intermediate outcomes of diabetes care and the percentage achieving recommended levels varied slightly but were not statistically or clinically significant. CONCLUSIONS: Few differences in the quality of diabetes care were found between urban and rural Indian health sites. Differences in the receipt of dental examinations may reflect differences in resources and staffing between urban and rural settings. This study serves as a baseline for the assessment of ongoing interventions aimed at improving the quality of care.

Measuring the quality of diabetes care for older american indians and alaska natives.

OBJECTIVES: This study evaluated the quality of diabetes care for older American Indians and Alaska Natives. METHODS: We analyzed the Indian Health Service Diabetes Care and Outcomes Audit to determine whether completion of indicators of diabetes care differed as a function of age and whether additional patient and program factors were also associated with completion of the majority of the indicators. RESULTS: Completion rates varied by age group, with significantly lower rates seen among the youngest and oldest. Patient diabetes education and duration of diabetes were most strongly associated with the completion of the majority of these indicators. CONCLUSIONS: Further studies are needed to determine effective interventions, including diabetes education, to improve the quality of diabetes care in the youngest and oldest age groups.
