净利润与现金流量差异的产生与项目调整

企业净利润与现金流量是企业管理中两个重要概念,在企业整个存续期间二者在数额上是相等的,但在某一会计期间,由于采取不同的会计概念和时间推移二者在数额上会有所不同,通过对不涉及现金的收入支出、应收应付、存货、递延税款等项目的调整可使二者数额达到一致。

《茂名市工业污染物排放标准》修订探讨

茂名市工业污染物地方排放标准是1981年底完成的,在防治污染和改善城市环境质量上起了重要的作用。随着工业的迅速增长,地方排放标准的不足之处也显现出来,特别是没有包括炼油厂的重要污染物,因此,严格标准控制污染是必要的。文中提出了地方排放标准修订的内容和方法。

Identification of ICD codes suggestive of child maltreatment

Objective

In order to be reimbursed for the care they provide, hospitals in the United States are required to use a standard system to code all discharge diagnoses: the International Classification of Disease, 9th Revision, Clinical Modification (ICD-9). Although ICD-9 codes specific for child maltreatment exist, they do not identify all maltreatment-related hospital and emergency department discharges. To increase the usefulness of medical data for public health surveillance of child maltreatment, this project sought to identify ICD-9 codes that are suggestive of child maltreatment.

Methods

After review of the literature and discussions with experts, injuries and conditions that should raise suspicion of child maltreatment (physical or sexual abuse or neglect) were identified and a list of corresponding ICD codes was compiled. Using a statewide electronic database of hospital discharges and emergency department (ED) visits for the year 2000, visits by children assigned these ICD codes were identified, a sample of visits was selected, and medical records were reviewed to assess the circumstances of the injury or illness that led to the visit. Based on information in the medical record, the injury or illness was classified as maltreatment-related, or not.

Results

There were 3,684 visits selected for review. Of these, 2,826 records were reviewed and classified; 1,200 (43%) records met the criteria for being maltreatment-related, 1,419 (50%) contained adequate information indicating the injury/condition was not likely maltreatment-related, and 207 (7%) records did not contain enough information to classify. Sixty-eight ICD codes had >66% of visits classified as maltreatment-related, the a priori criteria for a code to be considered suggestive of maltreatment. Codes suggestive of maltreatment include specific fractures, burns, and injuries of undetermined intent, among others.

Conclusion

Several ICD codes were found that, when used with age restrictions and other specific exclusion criteria, are suggestive of maltreatment. This information may increase the usefulness of hospital discharge data for public health surveillance of child maltreatment.

Practice implications

Use of these suggestive codes facilitates identifying conditions and injuries that are likely maltreatment-related in hospital discharge and ED visit data. When used in conjunction with ICD maltreatment-specific codes, these suggestive codes may enhance the use of medical data for monitoring child maltreatment trends.
