Aim: To examine the effects of life review on daily activities, social participation, outlook on life, and perceptions of living in a nursing home measured by life satisfaction and quality of life in older adults. Method: The study design was a two-phase quasi-experimental pre-post-tests including development and testing of a life review protocol. Nine residents, age ≥65, participated in a life review group once weekly for 6 weeks. Outcomes were analyzed using the Life Satisfaction Index-Z (LSI-Z) and pre-post surveys. Results: LSI-Z scores improved post-intervention and survey outcomes indicated participation in activities of daily living (ADLs), socialization, outlook on life, and living in a nursing home perceptions improved for all participants. Conclusion: The study demonstrates the effectiveness of a life review protocol to improve ADLs, social participation, and enhancing perceptions of outlook on life and living in a nursing home enhancing QOL and life satisfaction for older adult nursing home residents. 相似文献

Context
Do-not-resuscitate (DNR) orders are common among children receiving palliative care, who may nevertheless benefit from surgery and other procedures. Although anesthesia, surgery, and pediatric guidelines recommend systematic reconsideration of DNR orders in the perioperative period, data regarding how clinicians evaluate and manage DNR orders in the perioperative period are limited.Objectives
To evaluate perioperative management of DNR orders at a tertiary care children's hospital.Methods
We reviewed electronic medical records for all children with DNR orders in place within 30 days of surgery at a tertiary care pediatric hospital from February 1, 2016, to August 1, 2017. Using standardized case report forms, we abstracted the following from physician notes: 1) patient/family wishes with respect to the DNR, 2) whether preoperative DNR orders were continued, modified, or suspended during the perioperative period, and 3) whether life-threatening events occurred in the perioperative period. Based on data from these reports, we created a process flow diagram regarding DNR order decision-making in the perioperative period.Results
Twenty-three patients aged six days to 17 years had a DNR order in place within 30 days of 29 procedures. No documented systematic reconsideration took place for 41% of procedures. DNR orders were modified for two (7%) procedures and suspended for 15 (51%). Three children (13%) suffered life-threatening events. We identified four time points in the perioperative period where systematic reconsideration should be documented in the medical record, and identified recommended personnel involved and important discussion points at each time point.Conclusion
Opportunities exist to improve how DNR orders are managed during the perioperative period. 相似文献87.

BackgroundThe aim of this study is to explore the indirect effects of dispositional hope in the life satisfaction of older adults attending a lifelong learning program at the University of Valencia, Spain. We examine the mediating impact of dispositional hope regarding its ability to impact life satisfaction while considering affective and confidant social support, perceived health and leisure activities, consciousness and spirituality as predictors.MethodsAnalysis were based on survey data (response rate 77.4%) provided by 737 adults 55 years old or more (Mean age = 65.41, SD = 6.60; 69% woman). A structural model with latent variables was specified and estimated in Mplus.ResultsThe results show the ability of just a few variables to sum up a reasonable model to apply to successful aging population. All these variables are correlated and significantly predict hope with the exception of health. The model additionally includes significant positive indirect effects from spirituality, affective support and consciousness on satisfaction. The model has a good fit in terms of both the measurement and structural model. Regarding predictive power, these comprehensive four main areas of successful aging account for 42% of hope and finally for one third of the life satisfaction variance.ConclusionsResults support the mediating role of dispositional hope on the life satisfaction among older adults attending lifelong learning programs. These findings also support the MacArthur model of successful aging adapted to older adults with high levels of functional, social and cognitive ability. Dispositional hope, perceived health, and social support were the strongest predictors of satisfaction with life. 相似文献

AimTo evaluate the cost-effectiveness of [177Lu]Lu-DOTA-TATE versus relevant comparators for the treatment of neuroendocrine tumours located in the gastrointestinal tract (GI-NETs) and the pancreas (P-NETs).Materials and methodsA three-state partitioned survival model was developed to perform a cost-utility analysis of [177Lu]Lu-DOTA-TATE versus standard of care (high dose Octreotide LAR), everolimus and sunitinib. Effectiveness data for SoC, everolimus and sunitinib were obtained from published Kaplan–Meier survival curves. Given a lack of head-to-head effectiveness data, matching adjusted indirect comparisons (MAICs) were performed to population-adjust [177Lu]Lu-DOTA-TATE survival data based on prognostic factors and derive estimates of relative effectiveness. Health state utilities were estimated from real-world evidence. Drug acquisition costs were taken from nationally published sources (BNF, NICE), and administration costs were based on treatment protocols in [177Lu]Lu-DOTA-TATE studies, combined with nationally published unit costs (PSSRU, DoH reference costs). Incidence of adverse events were estimated using published sources. A discount rate of 3.5% was applied to both utilities and costs, and deterministic and probabilistic sensitivity analyses were performed. Costs were included from an NHS perspective and presented in 2017/18 GBP (and PPP Euros for base case).ResultsIn GI-NETs, the incremental cost-effectiveness ratio (ICER) of [177Lu]Lu-DOTA-TATE compared to SoC and everolimus was £26,528 (€27,672) and £24,145 (€25,186) per QALY, respectively. In P-NETs, the ICER of [177Lu]Lu-DOTA-TATE compared to SoC was £22,146 (€23,101) or £28,038 (€29,251) dependent on matched population, and £21,827 (€22,766) and £15,768 (€16,445) compared to everolimus and sunitinib, respectively.ConclusionsAt a willingness to pay threshold of £30,000, [177Lu]Lu-DOTA-TATE is likely to be a cost-effective treatment option for GI-NET and P-NET patients versus relevant treatment comparators (NHS perspective). 相似文献
