Validity and reliability of a pediatric patient classification instrument

OBJECTIVES:

to assess the construct validity and reliability of the Pediatric Patient Classification Instrument.

METHODS:

correlation study developed at a teaching hospital. The classification involved 227 patients, using the pediatric patient classification instrument. The construct validity was assessed through the factor analysis approach and reliability through internal consistency.

RESULTS:

the Exploratory Factor Analysis identified three constructs with 67.5% of variance explanation and, in the reliability assessment, the following Cronbach''s alpha coefficients were found: 0.92 for the instrument as a whole; 0.88 for the Patient domain; 0.81 for the Family domain; 0.44 for the Therapeutic procedures domain.

CONCLUSIONS:

the instrument evidenced its construct validity and reliability, and these analyses indicate the feasibility of the instrument. The validation of the Pediatric Patient Classification Instrument still represents a challenge, due to its relevance for a closer look at pediatric nursing care and management. Further research should be considered to explore its dimensionality and content validity.     

Occupational stress factors and alcohol-related behavior in urban transit operators

BACKGROUND: If alcohol consumption mitigates psychological and physiological aspects of the response to stressors, then alcohol consumption might be elevated for individuals exposed to high occupational stressors. Frequency of work stressors and reaction to those stressors were studied in relation to several alcohol-related outcomes. METHODS: During the period 1993-1995, 1979 transit operators underwent medical examinations for commercial driver's license renewal. Questionnaire and interview data concerning occupational stress factors and alcohol-related outcomes were available for 1386 (70.2%) of the operators. RESULTS: A positive association was found between the two job stressor-related measures and each of six alcohol-related outcomes. Of these 12 associations, ten were statistically significant. Individuals experiencing high self-reported frequency of job stressors and a higher perceived severity of those job stressors were more likely to drink and more likely to be heavy drinkers. They reported more consequences of alcohol consumption, reported increased consumption since beginning work as transit drivers, and were more likely to report drinking to deal with work stress. They also drank more, but this effect was not significant for either job stress measure. There was virtually no association between either stressor-related measure and alcohol dependency (CAGE). CONCLUSIONS: Together with other published findings, these results suggest increased alcohol-related outcomes in the presence of work stressors. This conclusion has potential implications for worksite health promotion and job design. Because our findings are cross-sectional, further research is needed to clarify the causal nature of the work stressor-alcohol association. Further research also is needed to clarify the role of individual differences and context.     

次任务技术对追踪负荷的测评敏感性

目的旨在研究次任务技术用于视觉追踪作业工作负荷测评的敏感性。方法采用模拟作业情境和主、次任务技术。主任务为追踪作业，分４种状况，以平均追踪误差距离为绩效指标，次任务是以几何图形为刺激目标的记忆搜寻作业，以目标反应时变化率和总反应时变化率为绩效指标，采用重复测量的受试者内设计。结果发现次任务绩效指标对追踪负荷具有较高的测评敏感性，但与主任务测定结果存在差异。结论次任务技术的敏感性受操作者资源分配策略倾向的显著影响。

模拟飞行条件下双重任务时飞行员心理生理参数的变化特点

测量了50名健康飞行员和13名康复疗养飞行员，在模拟飞行条件下双重任务时的心理生理反应。结果发现，模拟飞行各阶段心率变化趋势与实际飞行基本一致，但变化幅度较低。双重任务时，反映情绪性变化的心率、呼吸率及肺通气量明显增加，与思维活动有关的眨眼率增加。心理运动反应速度与飞行操纵质量相互影响，其程度有个体差异。同时在该负荷环境下，发现5例心律失常的无症状飞行员。结果提示，模拟飞行双重任务条件可以造成飞行员心理生理负荷，并可能有助于发现一些潜在性病症。

Estimating nurses' workload using the Diagnosis Procedure Combination in Japan

Aim:  To examine the methods used to estimate nurse staffing levels in acute care settings with Diagnosis Related Groups, which in Japan are called the Diagnosis Procedure Combination (DPC).
Methods:  For estimating staffing requirements, the study used four DPC groups: (1) acute or recurrent myocardial infarction (AMI) with stenting, (2) angina pectoris with coronary artery bypass grafting (CABG), (3) sub-arachnoid haemorrhage (SAH) with clipping surgery, and (4) cerebral infarction with carotid endarterectomy (CEA). Registered nurses with more than 3-year nursing experience in nine university hospitals in the Tokyo metropolitan area completed self-report questionnaires in order to obtain nursing care time and care intensity per each DPC. The concordance rate was measured by Kendall's coefficient of concordance. The relationship between the care time and the care intensity was examined by a time series graph per DPC. Care intensity consisted of professional judgement, mental effort for helping patients, professional skill, physical effort for providing activities of daily living support, and nurse stress, based on the Hsiao and colleagues' model of resource-based relative value scale.
Results:  Twenty-five nurses in nine university hospitals answered for a hypothetical typical patient with AMI and with CABG, and 28 nurses in nine university hospitals answered for a hypothetical typical patient with SAH and with CEA. Kendall's coefficient of concordance was 0.896 for AMI, 0.855 for CABG, 0.848 for SAH, 0.854 for CEA. The time series data of the care time and the care intensity items showed different patterns for each DPC.
Conclusion:  The DPC for cardiovascular and cerebral surgical procedures can be used for estimating nurses' workload.     

Work stress and workload of full-time anesthesiologists in acute care hospitals in Japan

Purpose  The number of anesthesiologists per population in Japan is small compared with that in Europe and North America. While there is a growing concern that hard work causes anesthesiologists’ fatigue and may compromise patient safety, the workload and physical stress, as well as the impact of staff support on physicians’ stress have not been assessed in detail. The goal of this study was to evaluate the working environment, anesthesia workload, and occupational stress of anesthesiologists in Japan. Methods  A questionnaire survey was performed targeting 1010 members of the Japanese Society of Anesthesiologists working as anesthesiologists affiliated with acute care hospitals in Japan. Data on background information, working environment, operation anesthesia duties, and stress were collected, and the relationship of work stress with background, environment, and anesthesia duties was evaluated by linear regression analysis. Results  Responses were obtained from 383 full-time anesthesiologists (response rate, 43.9%). The total anesthesia time per week was 23.6 h on average. The work stress score was 114.3 ± 30.2 (mean ± SD) when the average workers’ work stress score in Japan was 100. The work stress score was significantly associated with “years of experience” (with experience < 10 years considered as the reference; 10–19 years: β = −0.18, P = 0.02, ≥20 years: β = −0.15, P = 0.04), “hospital with ≥500 beds” (with a hospital with ≤ 299 beds considered as the reference; β = 0.15, P = 0.04), “total time of anesthesia per week” (β = 0.18, P.02), “estimated annual cases managed by an anesthesiologist” (β = 0.12, P = 0.04) and “no-support stress” (β = 0.21, P < 0.01) on linear regression analysis (R² = 0.12). Conclusion  Our results provide a quantitative assessment of the duties of anesthesiologists and show that work stress among anesthesiologists is related to workload and other factors. Summaries of this study were presented at the 53rd and 54th General Meetings of the Japanese Society of Anesthesiologists (JSA) at Kobe (2006) and Sapporo (2007).
