RESUMO
PURPOSE: Oral cancer is the sixth most common cancer worldwide and is the seventh most common in Botswana. Lack of improvement in oral cancer survival despite the availability of multiple treatment options may be due to the high prevalence of advanced stage at presentation. We identified risk factors for presenting with oral cancer at an advanced stage to facilitate interventions to reduce mortality from oral cancers. METHODS: A retrospective cohort analysis was conducted among individuals with biopsy-confirmed oral cancer at Princess Marina Hospital in Gaborone, Botswana, between 2010 and 2020. Data collected included age at diagnosis, sex, place of residence, HIV status, oral cancer stage, and oral subsite. Multivariable analyses were controlled for age, sex, district of residence, and oral subsite. RESULTS: Of the 218 records analyzed, 79% were male, 58% were HIV-positive, the median age was 56 years (interquartile range: 47-63), and 67% presented with advanced-stage disease. Cancers from hidden oral sites were more likely to present at an advanced stage with an adjusted odds ratio (OR) of 2.98 (95% CI, 1.29 to 6.89; P = .01). Residence in socioeconomically disadvantaged districts was associated with higher likelihood (OR, 2.36; 95% CI, 1.28 to 4.39; P = .01) of advanced stage presentation compared with other districts. HIV infection was not associated with risk of advanced lesion presentation (OR, 1; 95% CI, 0.61 to 1.61; P = .97). CONCLUSION: Hidden oral cancer sites and residence in districts with limited access to care were risk factors for advanced oral cancer at the time of diagnosis in Botswana. These findings support a need to increase efforts to improve access to care and increase oral cancer awareness to decrease the burden of advanced oral cancer.

OBJECTIVES: As ICUs are increasingly a site of end-of-life care, many have adopted end-of-life care resources. We sought to determine the association of such resources with outcomes of ICU patients. DESIGN: Retrospective cohort study. SETTING: Pennsylvania ICUs. PATIENTS: Medicare fee-for-service beneficiaries. INTERVENTIONS: Availability of any of one hospital-based resource (palliative care consultants) or four ICU-based resources (protocol for withdrawal of life-sustaining therapy, triggers for automated palliative care consultation, protocol for family meetings, and palliative care clinicians embedded in ICU rounds). MEASUREMENTS AND MAIN RESULTS: In mixed-effects regression analyses, admission to a hospital with end-of-life resources was not associated with mortality, length of stay, or treatment intensity (mechanical ventilation, hemodialysis, tracheostomy, gastrostomy, artificial nutrition, or cardiopulmonary resuscitation); however, it was associated with a higher likelihood of discharge to hospice (odds ratio, 1.58; 95% CI, 1.11-2.24), an effect that was driven by ICU-based resources (odds ratio, 1.37; 95% CI, 1.04-1.81) rather than hospital-based resources (odds ratio, 1.19; 95% CI, 0.83-1.71). Instrumental variable analysis using differential distance (defined as the additional travel distance beyond the hospital closest to a patient's home needed to reach a hospital with end-of-life resources) demonstrated that among those for whom differential distance would influence receipt of end-of-life resources, admission to a hospital with such resources was not associated with any outcome. CONCLUSIONS: ICU-based end-of-life care resources do not appear to change mortality but are associated with increased hospice utilization. Given that this finding was not confirmed by the instrumental variable analysis, future studies should attempt to verify this finding, and identify specific resources or processes of care that impact the care of ICU patients at the end of life.
