Although symptoms of anxiety and depression correlate, they may covary in irregular and unpredictable ways. This non-linear covariation may be important to psychiatric diagnosis, treatment and relapse. This non-linear anxiety-depression interaction suggests that power laws may be observed. Power laws are statistical distributions found when systems vary in complex ways at the interface between chaotic dynamics and periodic dynamics, such that data points vary randomly but are still partially correlated with each other. Such non-linear dynamics and relationships should result in characteristic patterns of interaction among patients, stressors and treatment. This is important because non-linear dynamics could affect our understanding of mental disorders, the need for varied treatment approaches and patterns of early response to treatment. ⋯ First, power laws suggest a scale-free relationship; the differences seen in transition from symptom level to change level may reflect that complex events at the level of mood assessment affect change in mood. Second, this covariation may be due to external factors acting on the patient or multiple internal interrelated factors. Third, different factors and populations can yield different slopes. Future research is needed to confirm these preliminary findings and to understand the origin of these dynamics.

Inadequate surgical implantation of a hip replacement may result in decreased patient satisfaction and reduced implant survival. The objective was to monitor surgical performance in hip replacement. ⋯ This study has demonstrated that implementing a dedicated system to monitor surgical performance in a teaching hospital improves the quality of implantation of total hip replacements. Nonetheless, the target of ninety percent of adequate primary total hip replacement could not be reached and efforts should be continued.

The purpose of this paper is to argue the importance of contemporary analysis of the modern social construction of chronicity--encapsulating the world views of the chronically ill, and the medical and health system constructions of chronic disease, through the nature of care for chronic conditions. It is argued that chronic diseases are themselves, socially constructed, despite widely accepted disease classification systems. Thus, there is a need to examine how different ideas have permeated our clinical and health system developments and their social context and vice versa. ⋯ Health care systems cannot afford to avoid, and should actively embrace the critiques of social theory and analyses in the transformations of health systems to improve chronic care. Creative tensions between empirical and intellectual critique, and a synthetic middle ground are likely to lead to more realistic and innovative approaches spanning the nature of chronicity and the transformation of Primary Care.

Wristbands are essential for accurate patient identification. Some evidence suggests that missing wristbands is not an infrequent occurrence in acute hospitals. The National Patient Safety Agency (NPSA) has developed guidance on patient identification for hospitals in England and Wales. Here we report an evaluation of the uptake of the guidance. ⋯ Overall, implementation of NPSA guidance regarding inpatient identification was satisfactory. The reported problems should be taken into account, as they likely apply to a range of patient safety interventions. Limitations of evaluating intervention uptake, rather than efficacy, and relying on self-report are discussed.

Hospital pharmacy aims at optimizing pharmaceutical care practice. Classically, assessing patient's satisfaction is required. Same manner, for a service provider such as a hospital pharmacy, it is necessary to evaluate the satisfaction of its customers: physicians, nurses and pharmacy staff. The aim of this paper was to assess user satisfaction with an individualized dispensing system. ⋯ An evaluation of a service or a practice should include an assessment of how well the service meets the needs of the user and how well the service is provided. A comprehensive, reliable and valid instrument for assessing user's satisfaction with individualized dispensing system is then available in our hospital. This paper demonstrated the interest of using simple and robust tools in professional practice.
