Ensuring quality of care in a comprehensive mental health center.

A six-phase process is currently being utilized by a large comprehensive mental health center to ensure delivery of the highest quality of care to its patients. In the first phase, during the admission process, each patient's assets and liabilities are determined. The second phase involves a disposition team that reviews and assigns each case. The third phase involves both the clinician and patient in developing a treatment plan. The fourth phase is a periodic review of each patient's file by the clinician's supervisor. The fifth phase involves a peer review of randomly selected files. The final phase is a retrospective review of randomly selected patients who are no longer receiving services, comparing the current assets and liabilities with those on the initial assessment to determine if progress did occur and was sustained.

Assessment of a pilot child playground injury prevention project in New York State.

Following a child playground equipment injury prevention project conducted in New York State in 1977, there was a 42 per cent reduction in playground equipment hazards, and a 22.4 per cent reduction in playground related injuries treated in the two largest hospitals of one of the program sites. Knowledge about unsafe playground practices and equipment hazards improved after the workshops for playground personnel. This approach to injury prevention deserves further study.

The relationship between some measures of synaptic ultrastructure as a function of distance from the soma on lamprey reticulospinal neurons.

Synaptic junctions located on the dendrites of lamprey (Petromyzon marinus) reticulospinal neurons labelled with intracellularly-injected horseradish peroxidase were studied. The normal ultrastructure of the synaptic junctions was defined and several quantitative measures made from each junction in order to test the hypothesis that distally-located synapses are ultrastructurally different from those located at proximal dendritic sites. A total of 820 contacts from one neuron and 279 from a second neuron ranging from 20 to 340 microns from the soma were quantified. The vast majority of the presynaptic endings contained round, clear-cored vesicles and formed an asymmetrical membrane differentiation with the postsynaptic dendrite. A small fraction of the population contained flattened or pleomorphic vesicles and these synapses were equally distributed with respect to distance from the soma. Many of the terminals contained a few large dark- and clear-cored vesicles. Four quantitative measures of each synaptic contact were made. These included vesicle number, length of differentiated membrane, vesicle area and terminal area. Four ratios relating the different quantitative measures were also calculated. Each ratio or measurement from the synaptic junctions was plotted as a function of distance from the soma to determine if differences existed at any distance. It was found that synaptic junctions are uniformly similar and that distal junctions did not differ significantly (P greater than 0.05) from those at proximal dendritic sites. It is concluded that if distal synapses do compensate for their remote location they do this is some other way, possibly by increasing the number of synaptic contacts made by each presynaptic axon.

Early cerebro-craniofacial dysmorphogenesis in schizophrenia: a lifetime trajectory model from neurodevelopmental basis to 'neuroprogressive' process.

Understanding the temporal origin(s) of schizophrenia, through specifying the earliest identifiable pathology, might indicate when to look for etiological factor(s), what their nature might be, and how course of illness might evolve from these origins. From this premise, earlier formulations are elaborated to offer a rigorously data-driven model that roots schizophrenia in cerebro-craniofacial dysmorphogenesis, particularly along the mid-line but involving other structures, over weeks 9/10 through 14/15 of gestation. However, a brain that has been compromised very early in fetal life is still subject to the normal endogenous programme of developmental, maturational and involutional processes on which a variety of exogenous biological insults and psychosocial stressors can impact adversely over later pregnancy, through infancy and childhood, to maturation and into old age, to sculpt brain structure and function; it should be emphasised that the effects of such endogenous programmes and exogenous insults on such an already developmentally-compromised brain may be different from their effects on a brain whose early fetal origins were unremarkable. From these early origins, a lifetime trajectory model for schizophrenia from developmental basis to 'neuroprogressive' process is constructed. Thereafter, consideration is given to what the model can explain, including cerebral asymmetry and homogeneity, what it cannot explain, what empirical findings would challenge or disprove the model, what cellular and molecular mechanisms might underpin the model, and what are its implications.

Nurses' assessments and management of pain in children having orthopedic surgery.

The specific aims of this research project were to (a) describe selected verbal, nonverbal, and physiological arousal indicators of the child's pain; (b) describe which pain indicators were most influential to nurses in decision-making about interventions for managing the child's pain; (c) describe pain interventions used by nurses; (d) compare postoperative analgesic orders to recommended dosages for the children; and (e) explore relationships between the child's self-report of pain and medication dosages administered. Subjects included 19 children aged 5-17 years who experienced 20 orthopedic surgical procedures (one child had two surgeries one week apart). Data were collected by staff nurses for the first five days after surgery. Pain levels were reported using the Oucher Scale. Postoperative pain was reported at moderate levels and showed only a gradual decrease throughout the hospital stay. Nonverbal pain indicators included crying and tense face. The child's complaint of pain and reported Oucher scores were most influential in influencing nurses to intervene in the child's pain. Nonpharmacological comfort measures included positioning and reassurance. All children received medications for pain; 49% of the orders were within the recommended therapeutic dosage range. A small but significant correlation was found between the child's reported pain level and the morphine equivalents of pain medication received. Recommendations included development of nursing flow charts that provide space to record pain levels and nursing interventions, in-service education for nurses on nonpharmacological interventions, and further research with a larger sample and a single pain rating scale.

Learning needs of nurses working in Canada's First Nations communities and hospitals.

BACKGROUND: What are the learning needs of nurses providing services to Canada's First Nations Communities and Hospitals? First Nations (or Indian Band) are similar to communities except some comprise more than one geographic Native community. Aboriginal (or Native) individuals are members of the North American Indian, Inuit, or Métis peoples of Canada; those who reported being a Treaty or Registered Indian (with the Federal Government); or those who are members of an Indian Band/First Nation. METHOD: A Canada-wide survey was completed to determine the learning needs of nurses working with Canada's Aboriginal persons. RESULTS: Nurses indicated both broad and specific aspects of their clinical practice, which were important to their continuing education (CE) needs. Broad thematic areas for continuing education included the following: emergency/acute care and obstetrics/gynecology clinical skills, health and physical assessment, mental health, and prenatal and postnatal care. Specific areas nurses cited for CE included issues related to: victims of violence; non-compliant clients; substance abuse; and fetal alcohol syndrome. CONCLUSION: This study examined the learning needs of nurses working with Canada's Native people and provided a basis for comparing and contrasting CE issues of these nurses to other nurses working in remote locations around the world.
