Many different systems for the assessment of pain in newborns and infants have been tested for validity, rarely for reliability but never for sensitivity or specificity. We aimed to determine whether the assessment of an analgesic demand in the lower age group during the postoperative period is possible by observational methods only. In an repetitive and sequential prospective process for identifying observationable behaviour and measurable physiological parameters as indicators of a postoperative analgesic demand, 584 newborns, infants and young children were studied (7 prospective studies, 4238 observations). Twenty-six items were selected as suggested by current literature and for reasons of economy and practicability. The factor analyses resulted in a two-factorial solution with the behavioural items loading on one factor and the physiological parameters on the other (principal component analyses). The physiological parameters blood pressure, respiratory rate and heart rate were found to be unreliable and had no discriminant power to detect an analgesic demand during the postoperative period (discriminant analyses, ROC-curves). In newborns and infants, nine observational items were identified as equally selective, reliable, sensitive and specific to the assessment of postoperative analgesic demand, whereas in young children only five items could be identified (discriminant analyses, ROC-curves). For economic reasons, these five items (crying, facial expression, posture of the trunk, posture of the legs, motor restlessness) were chosen as the basis of an additional pain scale ranging from 0=no pain to 10=maximal (Children's and Infants' Postoperative Pain Scale, CHIPPS). Its internal consistency yielded values for Cronbachs' alpha with 0.92 for toddlers and 0.96 for infants. The coefficient for interrater reliability was 0.93. The scale was validated constructively by the intravenous administration of metamizol, tramadol, nalbuphine, piritramide and ketamine (repeated measures analysis of variance). The Toddler-Preschooler Postoperative Pain Scale and CHIPPS equally identified painfree situations or analgesic demand in 87.4%. In cases with definite pain, the score of CHIPPS was never below 4 points. Seventy-one toddlers gave verbal comments on their pain intensity: in 29 painfree situations the CHIPPS score was 3.0 and in 29 painful situations it was 5.7. The values for sensitivity and specificity of CHIPPS were calculated to be 0.92-0.96 and 0.74-0.95, respectively (discriminant analyses). We conclude that it is possible to determine postoperative analgesic demand in the low age group of children by using an observational system such as CHIPPS alone. 相似文献

目的了解我省涉外企业职业卫生现状及服务需求,为建立科学、有效的职业卫生管理机制提供参考依据。方法选择有代表性6个市(县、区)市的283家涉外企业为调查对象。对工作场所有害因素进行检测与工人职业健康检查,进行意向性问卷调查。结果283家涉外企业存在职业危害,接触职业病危害因素18448人。存在职业病危害因素的行业集中在纺织业、制衣业及机械业。职业病危害因素共检测1759个点,合格率60.09%;接触噪声与苯的工人听力下降与白细胞减少异常率增高。部分企业忽视职业卫生工作,对职业病危害因素监测与评价、建立职业卫生档案、职业健康体检、职业卫生管理与职业病防护不到位。结论目前我省涉外企业职业卫生状况不容乐观,应及时采取相应的预防对策与控制措施。 相似文献

OBJECTIVE: The objective of this study was to investigate help-seeking behaviour among persons with anxiety disorder and depression based on self-rating in a Norwegian population (the HUNT study). METHOD: Of the 92 100 inhabitants aged 20-89 years invited, 65 648 (71.3%) took part. Among them 60 869 (66.1%) persons delivered valid ratings on hospital anxiety and depression scale, and had answered the requested help for mental problems question. RESULTS: Among HUNT attenders 13% of those with depression and 25% with anxiety disorders had been help seekers. Help seeking was only non-significantly associated with demographic or other variables. CONCLUSION: Most persons with anxiety disorder and/or depression in the population had not sought help for their mental disorders, but the disparity between use and need of health service must not be overassessed. Improvement of the help-seeking rate for common mental disorder should have high priority in mental health politics. 相似文献

Abstract.
Background:
Mathematical models relating rates of mental health care use to population characteristics such as social deprivation are widely used in both planning and researching mental health services. The models currently in wide use in England are based on data mostly derived from the 10-yearly population censuses. These are perceived to be out of date many years before new census data are available for their replacement. A new set of government deprivation monitoring statistics based mainly on annually updatable data has recently been developed. This study set out to produce a mental illness needs index based on these new data.
Methods:
A series of regression models were tested using individual domain scores from the DETR Index of Multiple Deprivation and the Office of National Statistics area-type classification as independent variables to predict 1998/9 psychiatric admission rates for broad diagnostic groups for 8251 of the 8414 electoral wards in England as dependent variables.
Results:
The distribution of admission numbers in wards showed a pattern of over-dispersion with an excessive number of zero values for conventional regression approaches. A two-stage hurdle model was, thus, adopted, predicting first the likelihood that wards would produce any admissions and second the probable number. This produced satisfactory predictive power, with residual variance showing strong geographical patterns associated with administrative areas, probably arising from differential resourcing or idiosyncratic clinical practice.
Conclusions:
A website providing data on the various indicators has been provided and its uses are indicated. 相似文献

PURPOSE: To determine whether the terrorist attacks on September 11, 2001, affected the health of persons far from the attacks, we studied rates of urgent and emergency medical evaluations among the 3 million persons enrolled in a managed care plan in Northern California. METHODS: Using a computerized database of all urgent care and emergency department evaluations, we monitored physician diagnoses made during the 6 weeks before and after September 11, 2001, at 16 hospitals in the Kaiser Permanente Medical Care Program. Actual rates of evaluations and diagnoses were compared with expected rates based on similar periods in 1998, 1999, and 2000. RESULTS: There were 4260 fewer urgent and emergent medical evaluations than expected during the 6 weeks beginning September 11, 2001 (-4%; 95% confidence interval [CI]: -3% to -5%; P <0.0001; N = 95,603). Emergency department visits occurred at the expected rate (-1%; 95% CI: -2% to 1%; P = 0.34), but urgent care visits were reduced (-9%; 95% CI: -8% to -11%; P <0.0001). Evaluations were particularly less frequent during the week beginning September 11 (-7%; 95% CI: -4% to -9%; P <0.0001), but a decrease persisted afterwards. Compared with expected rates, injuries (P <0.0001) and ill-defined/symptom-related diagnoses (P <0.0001) were less frequent, while gastrointestinal diagnoses (P = 0.01) were more frequent, during the 6 weeks after the attacks. Total urgent and emergent evaluations were mostly unchanged on September 11; only diagnoses associated with cardiac ischemia were more frequent (+70%; 95% CI: 10% to 163%; P = 0.02). CONCLUSION: Total urgent and emergent medical evaluations in a California managed care plan were reduced during the 6 weeks after the September 11th attacks. These results may help in allocation of resources during national disasters. 相似文献
