Concordance Between Self-Reported Completion of Advance Care Planning Documentation and Availability of Documentation in Australian Health and Residential Aged Care Services.

CONTEXT: Advance care planning (ACP) documentation needs to be available at the point of care to guide and inform medical treatment decision-making. OBJECTIVE: To examine concordance between self-reported completion of ACP documentation and self-reported storage of the documentation at the person's current point of care with the availability of the documentation in that person's health record. METHODS: A national multicenter audit of health records and a self-report survey of eligible audit participants in 51 Australian health and residential aged care services. The audit assessed availability of ACP documentation in the health record, whereas the survey assessed self-reported completion and storage of the ACP documentation at the person's current place of care. To ascertain concordance, survey and audit data were cross-tabulated and concordance rates and kappa statistics were calculated overall and by health care sector and ACP documentation type. RESULTS: The audit included 2285 people, of whom 1082 were eligible for the survey. Of 507 who completed the survey (response rate = 47%), 272 (54%) reported completing ACP documentation, of whom 130 (48%) had documentation identified in the audit. Conversely, 39 of 235 people (17%) who reported not completing ACP documentation had documentation identified (concordance rate = 64%; κ = 0.303, P < .001). The concordance rate increased to 79% when self-reported storage of ACP documentation at the person's current point of care was compared with the existence of the document in their health record (κ = 0.510, P < .001). Concordance varied by health care setting and type of ACP documentation. CONCLUSION: Discrepancies exist between self-reported completion of ACP documentation and the presence of these documents in the health records of older adults, representing a significant patient safety issue. Public education campaigns and improvements to systems for document storage and accessibility are required to support person-centered medical and end-of-life care.

Charlie Gard: in defence of the law.

Much of the commentary in the wake of the Charlie Gard litigation was aimed at apparent shortcomings of the law. These include concerns about the perceived inability of the law to consider resourcing issues, the vagueness of the best interests test and the delays and costs of having disputes about potentially life-sustaining medical treatment resolved by the courts. These concerns are perennial ones that arise in response to difficult cases. Despite their persistence, we argue that many of these criticisms are unfounded. The first part of this paper sets out the basic legal framework that operates when parents seek potentially life-sustaining treatment that doctors believe is against a child's best interests, and describes the criticisms of that framework. The second part of the paper suggests an alternative approach that would give decision-making power to parents, and remove doctors' ability to unilaterally withhold or withdraw life-sustaining treatment that they regard is futile. This proposal is grounded in several values that we argue should guide these regulatory choices. We also contend that the best interests test is justifiable and since the courts show no sign of departing from it, the focus should be on how to better elucidate the underlying values driving decisions. We discuss the advantages of our proposed approach and how it would address some of the criticisms aimed at the law. Finally, we defend the current role that the judiciary plays, as an independent state-sanctioned process with a precedent-setting function.

The role of law in decisions to withhold and withdraw life-sustaining treatment from adults who lack capacity: a cross-sectional study.

OBJECTIVES: To determine the role played by law in medical specialists' decision-making about withholding and withdrawing life-sustaining treatment from adults who lack capacity, and the extent to which legal knowledge affects whether law is followed. DESIGN: Cross-sectional postal survey of medical specialists. SETTING: The two largest Australian states by population. PARTICIPANTS: 649 medical specialists from seven specialties most likely to be involved in end-of-life decision-making in the acute setting. MAIN OUTCOME MEASURES: Compliance with law and the impact of legal knowledge on compliance. RESULTS: 649 medical specialists (of 2104 potential participants) completed the survey (response rate 31%). Responses to a hypothetical scenario found a potential low rate of legal compliance, 32% (95% CI 28% to 36%). Knowledge of the law and legal compliance were associated: within compliers, 86% (95% CI 83% to 91%) had specific knowledge of the relevant aspect of the law, compared with 60% (95% CI 55% to 65%) within non-compliers. However, the reasons medical specialists gave for making decisions did not vary according to legal knowledge. CONCLUSIONS: Medical specialists prioritise patient-related clinical factors over law when confronted with a scenario where legal compliance is inconsistent with what they believe is clinically indicated. Although legally knowledgeable specialists were more likely to comply with the law, compliance in the scenario was not motivated by an intention to follow law. Ethical considerations (which are different from, but often align with, law) are suggested as a more important influence in clinical decision-making. More education and training of doctors is needed to demonstrate the role, relevance and utility of law in end-of-life care.

The effects of an ionic liquid on unimolecular substitution processes: the importance of the extent of transition state solvation.

The reaction of bromodiphenylmethane and 3-chloropyridine, which proceeds concurrently through both unimolecular and bimolecular mechanisms, was examined in mixtures of acetonitrile and an ionic liquid. As predicted, the bimolecular rate constant (k2) gradually increased as the amount of ionic liquid in the reaction mixture increased, as a result of a minor enthalpic cost offset by a more significant entropic benefit. Addition of an ionic liquid had a substantial effect on the unimolecular rate constant (k1) of the reaction, with at least a 5-fold rate enhancement relative to acetonitrile, which was found to be due to a significant decrease in the enthalpy of activation, partially offset by the associated decrease in the entropy of activation. This is in contrast to the effects seen previously for aliphatic carbocation formation, where the entropic cost dominated reaction outcome. This change is attributed to a lessened ionic liquid-transition state interaction, as the incipient charges in the transition state were delocalized across the neighbouring π systems. By varying the mole fraction of ionic liquid in the reaction mixture the ratio between k1 and k2 could be altered, highlighting the potential to use ionic liquids to control which pathway a reaction proceeds through.

The relationship between maximal repetition performance and muscle fiber type as estimated by noninvasive technique in the quadriceps of untrained women.

The purpose of this investigation was to establish a relationship between the number of repetitions an individual can complete at a predetermined load and their percentage of type II muscle fibers in their quadriceps. Subjects included 22 untrained women between the ages of 18 and 35. Day 1 consisted of noninvasive anthropologic testing, 1 repetition maximum (1RM) testing, and recording repetition performance at 70% 1RM. Day 2 consisted of isokinetic dynamometry to determine muscle fiber composition. Results were obtained and analyzed using the Pearson product correlation coefficient (r). The results demonstrated a fair-to-moderate relationship (Pearson r = -0.48, p = 0.02) that individuals with greater percentages of type II muscle fibers performed fewer repetitions at 70% 1RM. The results of this study demonstrate that muscle fiber type composition is an important variable to consider when designing training or rehabilitation programs.
