Name the government agency that has led the development of basic data sets for

health records and computer databases: - Answer National Committee on

Vital and Health Statistics

NHIN was mentioned first by the Institute of Medicine (IOM) in its seminal report, "The Computer-Based Patient Record: An Essential Technology for Health Care." A decade later, the National Health Information Infrastructure was defined further by the National Committee on Vital and Health Statistics (NCVHS) in its report "Information for Health: A Strategy for Building the National Health Information Infrastructure"

The application of information science to the management of healthcare data and

information through computer technology is referred to as: - Answer Health

Informatics

Health informatics and information management is concerned with the timely and accurate capture and processing of this transactional information. (LaTour et al.

2013, 158).

Community Memorial Hospital discharged nine patients on April 1. The length of stay for each patient is shown in the following table. The average length of stay for

these nine patients was:

Patient Number of Days A 1 B 5 C 3 D 3 E 8

F 8 3 / 4

G 8 H 9 I 9 - Answer 6 days

The average length of stay (ALOS) is calculated from the total LOS. The total LOS divided by the number of patients discharged is the ALOS. Using the data provided, the ALOS for the 9 patients discharged on April 1 is 6 days (54 / 9) (LaTour et al. 2013, 490; Shaw and Carter 2014, 23, 171).

Data mapping is used to harmonize data sets or code sets. The code or data set

In population-based registries, emphasis is on identifying trends and changes in the incidence (new cases) of cancer within the area covered by the registry (LaTour et al. 2013, 370).
