Abstract

Proximity calculations in metric space have found new applications recently with the increased emphasis on Internet searching. In this work we present a novel approach to Internet searching. We use a combination of metric space distance calculations and link analysis to determine the proximity of internet objects. This framework is generic and can be applied to various domains such as help desk support, human resources or geographical information systems. We provide an example within the text mining domain. We also provide the mathematical preliminaries, give a detailed example and discuss our results.

Abstract

Using a high-statistics sample of more than 1000 reconstructed charmed-particle decays, the lifetimes of the weakly decaying charmed mesons and of theΛc+ baryon have been measured: $$\begin{gathered} \tau _{D^ + } = 1.03 \pm 0.08 + 0.06 ps,\tau _{D^0 } = 0.417 \pm 0.018 \pm 0.015 ps \hfill \\ \tau _{D_s^ + } = 0.33_{ - 0.08}^{ + 0.12} \pm 0.03 ps,\tau _{\Lambda _c^ + } = 0.18 \pm 0.03 \pm 0.03 ps. \hfill \\ \end{gathered} $$

Abstract

Background: Noncancer patients with life-limiting diseases often receive more intensive level of care in their final days of life, with more cardiopulmonary resuscitation performed and less do-not-resuscitate (DNR) orders in place. Nevertheless, death is still often a taboo across Chinese culture, and ethnic disparities could negatively affect DNR directives completion rates., Objectives: We aim to explore whether Chinese noncancer patients are willing to sign their own DNR directives in a palliative specialist clinic, under a multidisciplinary team approach., Design: Retrospective chart review of all noncancer patients with life-limiting diseases referred to palliative specialist clinic at a tertiary hospital in Hong Kong over a 4-year period., Results: Over the study period, a total of 566 noncancer patients were seen, 119 of them completed their own DNR directives. Patients had a mean age of 74.9. Top 3 diagnoses were chronic renal failure (37%), congestive heart failure (16%), and motor neuron disease (11%). Forty-two percent of patients signed their DNR directives at first clinic attendance. Most Chinese patients (76.5%) invited family caregivers at DNR decision-making, especially for female gender (84.4% vs 69.1%; P = .047) and older (age >75) age group (86.2% vs 66.7%; P = .012). Of the 40 deceased patients, median time from signed directives to death was 5 months. Vast majority (95%) had their DNR directives being honored., Conclusion: Health-care workers should be sensitive toward the cultural influence during advance care planning. Role of family for ethnic Chinese remains crucial and professionals should respect this family oriented decision-making.

Abstract

Objectives: To examine the level of family satisfaction in a local intensive care unit and its performance in comparison with international standards, and to determine the factors independently associated with higher family satisfaction., Design: Questionnaire survey., Setting: A medical-surgical adult intensive care unit in a regional hospital in Hong Kong., Participants: Adult family members of patients admitted to the intensive care unit for 48 hours or more between 15 June 2012 and 31 January 2014, and who had visited the patient at least once during their stay., Results: Of the 961 eligible families, 736 questionnaires were returned (response rate, 76.6%). The mean (± standard deviation) total satisfaction score, and subscores on satisfaction with overall intensive care unit care and with decision-making were 78.1 ± 14.3, 78.0 ± 16.8, and 78.6 ± 13.6, respectively. When compared with a Canadian multicentre database with respective mean scores of 82.9 ± 14.8, 83.5 ± 15.4, and 82.6 ± 16.0 (P<0.001), there was still room for improvement. Independent factors associated with complete satisfaction with overall care were concern for patients and families, agitation management, frequency of communication by nurses, physician skill and competence, and the intensive care unit environment. A performance-importance plot identified the intensive care unit environment and agitation management as factors that required more urgent attention., Conclusions: This is the first intensive care unit family satisfaction survey published in Hong Kong. Although comparable with published data from other parts of the world, the results indicate room for improvement when compared with a Canadian multicentre database. Future directions should focus on improving the intensive care unit environment, agitation management, and communication with families.
