BackgroundRecent studies have described the use of telehealth for pediatric surgical care during the COVID-19 pandemic. We aimed to evaluate equity in telehealth use by comparing rates of utilization and satisfaction with pediatric surgical telemedicine among Hispanic patients.MethodsWe conducted a retrospective cohort study of patients seen by a surgical subspecialty provider in the outpatient setting at a quaternary pediatric hospital between April 1 and June 30, 2020. Patients evaluated in the same three-month period in 2019 were analyzed as a historic control. Differences in Family Experience Survey (FES) responses based on race and ethnicity and preferred language of care were assessed using univariable and multivariable generalized linear modeling.ResultsThe pandemic cohort included fewer patients of Hispanic ethnicity and fewer Spanish-speakers. After controlling for visit type, comparison of Spanish-speaking and English-speaking patients revealed that Spanish-speaking families had significantly lower scores for FES items that evaluated healthcare provider explaining (IRR 0.74, 95% CI: 0.61–0.90), listening (IRR 0.76, 95% CI: 0.63–0.92), and time spent with the family (IRR 0.73, 95% CI: 0.60–0.89). There were no differences in FES responses based on insurance status or degree of medical complexity.ConclusionsTelehealth services were less commonly used among Hispanic and Spanish-speaking patients. Language may differentially affect family satisfaction with healthcare and telehealth solutions. Strategies to mitigate these inequities are needed and may include strengthening interpreter services and providing language-concordant care.Level of evidenceLevel IV. 相似文献

BackgroundPatients with intellectual and developmental disabilities (IDD) are more likely to experience poor health outcomes and family physicians receive inadequate training to provide appropriate care to this patient group. Little prior research has studied how to effectively train family physicians to care for patients with IDD.ObjectiveThe aim of this pilot study was to assess the value of adding an experiential component to didactic education strategies to improve family medicine resident perceived comfort, skills and knowledge related to caring for patients with IDD.MethodsStructured education programs for residents were implemented at three primary care practices in Ontario, Canada. Two practices received didactic information only (didactic-only group); one received didactic information and an experiential training model including clinical interactions and a written reflection on that experience (didactic plus experiential group). In this separate-sample pre-post design, residents were invited to complete a brief anonymous survey prior to and following the training assessing their perceived comfort, skills and knowledge related to patients with IDD.ResultsAt baseline, there were no significant differences between the two groups of residents. At follow up, the experiential group reported significantly higher levels of comfort, skills, and knowledge compared to baseline for most items assessed, while in the didactic-only group most items showed little or no improvement.ConclusionThis pilot study suggests that providing residents the opportunity to participate in clinical encounters with patients with IDD, as well as a structured process to reflect on such encounters, results in greater benefit than didactic training alone. 相似文献

IntroductionLung cancer is the leading cause of cancer-death worldwide. The U.S. Preventative Services Task Force (USPTSF) approved screening for current or former smokers aged 55–80 based on the results of the National Lung Screening trial (NLST). Following the NLST, new evidence has emerged from clinical trials and updates to previous trials prior to the anticipated update to the USPSTF guideline. We review the new evidence on lung cancer screening with low dose computed tomography (LDCT) and the surgical implications.MethodsA review of new literature was performed pertaining to lung cancer screening since implementation of UPSTF guidelines. Articles for inclusion were identified by both authors’, then search of the Pubmed and Cochrane database was performed from January 1st, 2013 through February 4th, 2020 using the MeSH search terms: “lung cancer”; “screening”; “low dose CT”. The results of these studies are summarized.ResultsWe identified multiple prospective randomized control trials and meta-analysis since the NLST supporting lung cancer-specific mortality with screening. We identified new nodule classification systems and the development of risk-models which may reduce false positive rates and identify high risk patients not currently eligible for screening. Finally, we discussed the surgical implications of screening.ConclusionNew data supports NLST findings and show ongoing benefit to LDCT for lung cancer screening. Standardized LDCT screening classification has been shown to reduce harm and lower false positive rates. Further study is needed regarding use of risk-modeling. Screening will require an increase in the thoracic workforce to accommodate the amount of surgically operable cancers. 相似文献

The aim of this article is to examine how different ideological perspectives on Swedish disability policy, are reflected in the experiences of disabled people and their families personal assistants. Personal assistance provided within the family can be seen as a hybridization between publicly regulated and paid work performed in the private family sphere, and thus conflicting norms and practices may coexist. In Sweden, family members of the assistant user can be employed as paid personal assistants. Many users combine personal assistance from family members with non-family assistance. Approximately 20–25% of the employed personal assistants are relatives of the assistance users. The empirical data consists of qualitative interviews with seventeen adult users and twenty-three family members employed as PAs with different types of family ties; parent-child relationships, sibling relationships and partner relationships. The findings show that family assistance could entail advantages such as personalised services, to combine instrumental and emotional assistance as well as achieving a power-balance between the parties. But there were also disadvantages, such as unwanted or enforced dependency, with a risk for both parties to be ‘locked up’ in the family. In an overall analysis, we distinguished three broad approaches towards family assistance, family as a substitute, family as a supplement and family first. 相似文献

Purpose
To evaluate the quality of life (QoL) and social support among family caregivers of a family member with a mental illness and to identify factors associated with the QoL.Methods
This is a cross-sectional study, where participants were recruited and independently interviewed using a questionnaire, consisting of demographic characteristics, the Medical Outcome Survey SF-36 form, and social support rating scales. Multiple stepwise regression analysis was used to analyse the factors related to QoL.Results
181 family caregivers were recruited in Shandong province, China. On a composite QoL score, family caregivers perceived that their QoL was poor (68.3), especially in the aspects of role-physical (61.3), role-emotional (57.6) and mental health (63.0). We also found family caregivers received low social support, especially in objective support and utilization of social support. Patient's illness state, care time, financial burden and objective support were significantly correlated to caregivers' QoL in the physical component score (PCS). Patient's illness state, patient's marital status, family monthly income, caregiver's knowledge about the illness, caregivers coordinating caring, life and work, subjective support received and utility of support were significantly associated with caregivers' QoL in the mental component score (MCS).Conclusions
Social support had a significant correlation with caregivers' QoL. Caregivers should be encouraged to request assistance from other family members and friends in providing care, especially when caregivers are unemployed or long-time carers. Mental health education campaigns and helping families to maintain and enhance a supportive social network may provide useful means to improve caregivers' QoL. 相似文献8.
