Statistics have been utilized in the health care system since the 19th century. The statistical need of the American health care industry was identified since the introduction of Medicare and Medicaid programs in 1965. The rapid aging of the population, emerging of the chronic health conditions, the rapid growth of private insurance, increase morbidity and mortality, high complex care cautioned the system for future monitoring. Health statistics often are obtained via sample surveys conducted through telephone, mail, or in-person interviews of individuals and/or households. Health surveys go back to the Hagerstown morbidity studies conducted by the Public Health Service in the early 1920s. In 1953, a subcommittee of the U.S. National Committee on Vital and Health Statistics (NCVHS) recommended that a national health survey is established on a permanent basis. When CDC was established in 1946, the U.S Public health Service rented Florence Nightingale statistical method technique to implement sanitary measures in London. During 1950, s CDC conducted many activities to monitor infectious disease in many areas using chi-square and a p-value. The CDC, many public and private agencies conducted many valued studies and researches using statistics. Today, health care organizations employ statistical analysis to measure their performance outcomes. Hospitals and other large provider service organizations implement data-driven, continuous quality improvement programs to maximize efficiency. Government health and human service agencies gauge the overall health and well-being of populations with statistical information.
The statistics in health care provider information for understanding, examining, improving, and planning the practice of resources to enhance the lives of patients, provide service and promote their well-being. The use of statistics in health care and nursing profession includes research, quality improvement, disparities in health care, risk analysis, inventory management, cost, resource utilization, length of stay, satisfaction survey, clinical trials, mortality rates, effects of new treatments, hospital budgets, hours per patient day, patient flow chart, laboratory analysis, education, and much more.
Knowledge of statistics helps medical professionals evaluate studies that assess the efficacy of treatments and interventions. It also equips practitioners to conduct studies of their own, further benefiting patient care. In addition to providing scientific evidence that supports new medical advances, statistics in health care convey valuable information about the health of a society. The National Library of Medicine at the National Institutes of Health points out that statistics enable medical professionals and public health officials to gauge the disparities in health conditions among members of a population.
