Background

Treatment‐related mortality and abandonment of therapy are major barriers to successful treatment of childhood acute lymphoblastic leukemia (ALL) in the developing world.

Procedure

A collaboration was undertaken between Instituto Nacional de Cancerologia (Bogota, Colombia), which serves a poor patient population in an upper‐middle income country, and Dana‐Farber/Boston Children's Cancer and Blood Disorders Center (Boston, USA). Several interventions aimed at reducing toxic deaths and abandonment were implemented, including a reduced‐intensity treatment regimen and a psychosocial effort targeting abandonment. We performed a cohort study to assess impact.

Results

The Study Population comprised 99 children with ALL diagnosed between 2007 and 2010, and the Historic Cohort comprised 181 children treated prior to the study interventions (1995–2004). Significant improvements were achieved in the rate of deaths in complete remission (13% to 3%; P = 0.005), abandonment (32% to 9%; P < 0.001), and event‐free survival with abandonment considered an event (47% to 65% at 2 years; P = 0.016). However, relapse rate did not improve. Medically unnecessary treatment delays were common, and landmark analysis revealed that initiating the PIII phase of therapy ≥4 weeks delayed predicted markedly inferior disease‐free survival (P = 0.016). Conversely, patients who received therapy without excessive delays had outcomes approaching those achieved in high‐income countries.

Conclusions

Implementation of a twinning program was followed by reductions in abandonment and toxic deaths, but relapse rate did not improve. Inappropriate treatment delays were common and strongly predicted treatment failure. These findings highlight the importance of adherence to treatment schedule for effective therapy of ALL.

The substantial focus of resilience research on childhood well‐being has resulted in limited knowledge regarding other aspects of resilience in families, such as that of parents. Informed by literature in childhood and family resilience, in this review, we progress conceptual understanding by focusing on parental resilience. The definition of parental resilience, as the capacity of parents to deliver a competent and quality level of parenting to children despite the presence of risk factors, is offered here as a worthwhile framework through which to explore variables thought to contribute to resilience among parents. A conceptual model is proposed whereby parental psychological well‐being and self‐efficacy, family functioning, and social connectedness are specifically addressed, with each posited as playing an important role in parents’ ability to deliver high‐quality parenting. In addition to these factors, how parents accommodate adversity and find meaning in their everyday lives within their families is hypothesised to be an important process in understanding parental resilience.  相似文献

Objective

We aimed to evaluate patient perceptions of medical scribes in the ED and to test for scribe impacts on ED Net Promoter Scores, Press Ganey Surveys and other patient‐centred topics.

Methods

Exploratory semi‐structured interviews were conducted in the ED during wait times after scribed consultations. Interview results were used to derive topics relating to scribes. Items addressing these topics from validated surveys were combined with items from widely used patient satisfaction questionnaires. Questionnaires were administered in the ED by face‐to‐face approach while patients were waiting for admission/discharge or test results. Patients and doctors were blinded to the purpose of the questionnaire. The survey evaluated for non‐inferiority of scribed consultations, using Net Promoter Scores, Press Ganey questions and questions specific to the presence of the scribe.

Results

Patient interviews did not identify any negative views regarding the presence of scribes during consultations. Thematic saturation was achieved after seven interviews. Two hundred and fifty‐eight patients were approached to complete the questionnaire, and 215 participated (83%); 95 and 118 participants in the scribed and non‐scribed groups, respectively. There was no difference between scribed and non‐scribed consultations on the following measures of satisfaction: the Net Promoter Score, Press Ganey questions, quality of information received from doctors, communication, privacy concerns or inhibition about revealing private information and room crowding.

Conclusion

We found no evidence that scribes reduce patient satisfaction during emergency consultations, nor prompt discomfort that might cause a patient to withhold information.  相似文献
