Developing staff into clinical practitioners

Developing clinical skills in pharmacy staff is a process that can enhance the services of a pharmacy department and improve the professional development and interest of the staff. Staff should be included in the development of a clinical philosophy and a training and ongoing development program that will achieve the desired goals should be planned. An MBO process may help to track the individual pharmacist's progress. Knowledgeable, motivated staff are the key ingredient in achieving success in providing pharmacy services.     

Extending the application of critical path methods

Most health care organizations are using critical pathways in an attempt to reduce the variation in patient care, improve quality, enhance communication, and reduce costs. Virtually all of the critical path efforts to date have developed tables of treatments, medications, and so forth by day and have displayed them in a format known as a Gantt chart. This article presents a methodology for identifying the true "time-limiting" critical path, describes three additional methods for presenting the information--the network, precedent, and resource formats--and shows how these can significantly enhance current critical path efforts.     

Knee joint kinematics during the sidestep cutting maneuver: potential for injury in women.

PURPOSE: There is a paucity of data describing female lower limb biomechanics during "high risk" movements linked to noncontact ACL injury. This study compared, across gender, knee kinematics associated with sidestepping maneuvers to provide insight into why women display a significantly higher incidence of this injury than do men. METHODS: Thirty participants (16 men, 14 women) had bilateral knee joint kinematic data recorded while sidestepping. A custom software package (JTMOTION) quantified maximum, minimum, and range of motion during stance for each of the three clinical knee joint rotations (flexion/extension, adduction/abduction and external/internal rotation) over 20 (leg x condition x trial (5)) trials. RESULTS: Gender differences possessed limited clinical significance with all maximum values well within safe ranges of knee motion. Women did, however, display increased intertrial variability for axial rotation patterns during cutting compared with men. This variability was thought to be unaffected by gender, with experience level found statistically (P < 0.01) to be the major determinant of knee kinematic variability during sidestepping. Hence, the level of exposure to sidestep cutting may have a large impact on the subsequent risk of ACL injury when when one performs these maneuvers. CONCLUSIONS: Gender differences in knee motions during cutting did not contribute to the increased risk of noncontact ACL injury in women compared with men. The reasons for this increased incidence, therefore, remain unclear. The potential relationship between gender and other parameters linked to ACL injury such as joint geometry, ligament morphology, and physical conditioning requires further investigation.     

Diethyldithiocarbamate causes nigral cell loss and dopamine depletion with nontoxic doses of MPTP

Although nontoxic when administered alone, diethyldithiocarbamate (DDC) is known to enhance the dopamine-depleting effects of 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP) in the mouse striatum. The purpose of the present study was twofold: (i) to carefully characterize the effects of DDC on MPTP-induced degeneration of dopaminergic neurons in substantia nigra pars compacta using unbiased, stereological cell counting techniques and (ii) to determine whether or not DDC can convert a nontoxic dose of MPTP into one which is clearly toxic on dopaminergic neurons in the substantia nigra. A single low dose of MPTP (15 mg/kg intraperitoneally (ip)) was used for these studies, which failed to induce any neurochemical or histological effects on the nigrostriatal system of C57BL/6 mice when administered alone. However, when animals were pretreated with DDC (400 mg/kg ip), the same dose of MPTP resulted in a 50% loss of neurons in the substantia nigra pars compacta, as well as a 70% reduction in striatal dopamine (DA). A 31% reduction of DA in the ventral mesencephalon was also seen. This combined regimen of DDC and MPTP was not significantly different from a maximally tolerated "toxic" dose of MPTP alone (15 mg/kg x 4, 1 h apart, ip). As expected, animals receiving DDC alone did not show any dopamine depletion nor nigral neuronal loss. The present study confirms previous work suggesting that DDC enhances MPTP-induced nigral cell loss and shows for the first time that DDC can "unmask" MPTP toxicity. These observations could have implications for theories on the cause of Parkinson's disease.     

Interobserver variation in the assessment of pelvic organ prolapse

The aim of this study was to determine the interobserver agreement of two grading systems for pelvic organ prolapse: the vaginal profile and the International Continence Society (ICS) draft proposal. Forty-nine consecutive women referred for evaluation of urinary incontinence and/or pelvic organ prolapse were studied. Patients were first examined by a physician and a nurse clinician using the vaginal profile, followed by an examination according to the technique described in the ICS draft proposal for standardization of terminology (1994). statistic and Pearson's correlation coefficient were used to determine interobserver variability for the ICS system by overall stage, by stage-specific comparison, and by specific anatomic location. The vaginal profile was evaluated by obtaining a for overall degree of prolapse, stage-specific comparison and by anatomic area. The for the ICS stage was 0.79 (P<0.001), and the for the vaginal profile by area of greatest prolapse was 0.68 (P<0.001), indicating substantial interobserver agreement for both systems. The ICS system was noted to have substantial interobserver agreement by a stage-specific comparison. All anatomic locations of the ICS staging system were found to correlate significantly, and a high degree of interobserver precision was found. The vaginal profile also showed significant interobserver agreement by overall degree of prolapse, by specific degree of prolapse, and by anatomic area. It was concluded that both the proposed ICS staging system and the traditional vaginal profile show significant interobserver agreement both by overall stage, stage-specific analysis and specific location. The registered nurse examination correlated well with the physican examination, indicating that the most important factor in obtaining reproducible results may be definition and close attention to examination technique.EDITORIAL COMMENT: There has recently been a great deal of interest in the anatomy and physiology of the pelvic floor and the various investigative techniques to define its function. The lack of a standardized and reproducible system to describe pelvic organ prolapse through the hiatus of the pelvic floor has hampered research into its pathophysiology and treatment. The authors applied a validated statistic and Pearson's correlation coefficient to convincingly measure interobserver reliability for the ICS system and indicated an index of trend between points on the ICS scale as well.     

State mediation of conflicts over work refusals: the role of the Ontario Labour Relations Board.

A key feature of occupational health and safety legislation is that it has sought to compartmentalize health and safety issues by creating structures and processes that depart from "typical" social relations of production. The Ontario Labour Relations Board, in adjudicating disputes concerning work refusals, faces the difficult, if not impossible, task of defining and maintaining a sphere in which workers have an uncommon latitude and power. Analysis of cases before the Board during the 1980s shows how it errs on the side of caution and uses criteria related to "typical" social relations of production to define convincing testimony and assess workers' entitlement to redress. Similarly, employers' interests and the requirements of the labor process are a reference point in the Board's definition of the scope of workers' rights and what constitute legitimate penalties for the "abuse" of these. Yet decisions are not wholly biased toward employers; dissenting opinions reveal important differences and progressive rulings establish precedents that could be a basis for future decisions.
