Older female inpatients in Arkansas.

The purpose of this study was to examine age and Major Diagnostic Categories (MDCs) and compare the variables to mortality and length of stay among inpatient women age 50 and over. Archival statistical data were obtained for 2,238 inpatients in a private, nonprofit hospital in 1998. The ages ranged from 50 to 107 years old, with a mean age of 71.21 years. Quantitative analyses were conducted to examine the data from a private, nonprofit hospital and determine if there were significant relationships between age, major diagnostic category, length of stay, and mortality in older women. The MDC distribution indicated that the highest frequency of diseases and disorders were in the following three systems: circulatory system, musculoskeletal system and connective tissue, and the digestive system. The average length of stay was 8.01 days. The 30-day readmission percentage and the 365-day readmission percentage were 12.24% and 28.02%, respectively. The mortality rate was 6%. In addition, 63.97% went home after discharge, and 67.07% were Medicare recipients. The risk of musculoskeletal diseases and disorders increased with age (p = .0001). The conditional probability of death was nearly nine times higher for the diseases of the nervous system, myeloproliferative diseases and disorders, poorly differentiated neoplasms and respiratory diseases. As age increased, the probabilities of a long hospital stay decreased. The mortality analyses found that the lowest probabilities of survival were in categories of myeloproliferative diseases and disorders, poorly differentiated neoplasms, and infectious and parasitic diseases. According to current health statistics, our society is getting older. Not only are people living longer, they are accessing more health care (American Association for World Health, 1999). Overall, the average life expectancy at birth has been identified at 76.5 years. The female has a longer life expectancy than the male, averaging 5.8 years longer. The highest life expectancy has been identified in the white female, who can expect to live to 79. The black woman has the second-highest life expectancy, 74.7 years. Peters, Kochanek, and Murphy reported an all-time-low age-adjusted death rate for the United States and a continuing trend in the decline in mortality for all age groups. With a growing number of people living longer, there is a need to know about the most common health issues that affect quality of life. The top three national causes of death in older Americans were diseases of the heart, malignant neoplasms, and cerebrovascular diseases/stroke. Arkansas health statistics mirror the national statistics. In April 1999, the Arkansas Department of Health reported that 30.5% percent of all female deaths were caused by heart disease. Malignant neoplasms were responsible for 20.1%, followed by cerebrovascular diseases at 10.8%. Other than three Connecticut hospital studies that explored the relationship of diagnosis code, mortality, and readmission, research is meager in this area. There is a need for hospital-based research that addresses the diagnosis categories and the relationship to age and other variables.
