The US health care system is marked by a high degree of fragmentation in both delivery and financing. Some evidence suggests that attempts to reduce fragmentation have led to significant provider consolidation, including hospital acquisitions of physician groups, or "vertical integration." The objective was to use time-series data to quantify trends in and characteristics of hospital acquisitions of physician practices. A secondary objective was to use case studies to determine the motivations for these acquisitions and to identify what integration results from these transactions. ⋯ Among 4 case-studies of hospital acquisition of physician practices, the primary motivation was financial and competitive motivations. This suggests that policymakers should be mindful of the potential negative effects of these acquisitions on health care costs, as well as the uncertainty of clinical benefits. Policymakers may need supplementary strategies to deliver the goals of reduced costs and improved quality of care.

The objective of the study is to assess the completeness and accuracy of medication records held by stakeholders (secondary care, general practice, and community pharmacy) for clozapine consumers managed in a shared care programme. ⋯ Discrepancies were highly prevalent in the shared care medication records of clozapine consumers of this service. Where there is incomplete and inaccurate medication information, there is a risk of suboptimal clinical decision making, increasing the likelihood of adverse drug events. This study demonstrates a need for improved documentation and timely access to accurate and complete medication records for shared care stakeholders. Expanding the pharmacist's role in this setting could improve medication accuracy in documentation and related communication.

Physiotherapists are integral members of the intensive care unit (ICU) team. Clinicians working in ICU are dependent on their own experience when making decisions regarding individual patient management thus resulting in variation in clinical practice. No formalized clinical practice guidelines or standards exist for the educational profile or scope of practice requirements for ICU physiotherapy. This study explored perceptions of physiotherapists on minimum clinical standards that ICU physiotherapists should adhere to for delivering safe, effective physiotherapy services to critically ill patients. ⋯ The information obtained will be used to inform the development of a list of standards to be presented to the wider national physiotherapy and ICU communities for further consensus-building activities.

Adherence to medication regimen is commonly assessed through questionnaires, some of which are validated via self-administration. The inadequate health literacy of elderly people pushes researchers to the use of interviews as a method of administration. The aims of this study were to compare the results obtained with an interviewer-administered and a self-administered medication adherence questionnaire and to evaluate the consequences of the adherence status classification of individuals. ⋯ The interview administration method induced bias that led to a higher percentage of "never" answers and a subsequent overestimation of adherence levels. Self-report administration should be preferred in the application of medication adherence questionnaires.

Null hypothesis significance testing is the typical statistical approach in search of the truthfulness of hypotheses. This method does not formally consider the prior credence in the hypothesis, which affects the chances of reaching correct conclusions. When scientifically implausible or empirically weakly supported hypotheses are tested, there is an increased risk that a positive finding in a test in fact is false positive. ⋯ The problems with false positive findings are discussed, and advice is given on how to minimize the problem. The standard of evidence of a hypothesis should depend not only on the results of statistical analyses but also on its a priori support. Positive findings from studies investigating hypotheses with poor theoretical and empirical foundations should be viewed as tentative until the results are replicated and/or the hypothesis gains more empirical evidence supporting it as likely to be true.
