Preventable Hospitalizations for Congestive Heart Failure Article

Preventable Hospitalizations for Congestive Heart Failure - Article Example The independent variable in the study is from the year 1995 to 2009 while the dependent variable is preventable hospitalization for congestive heart failure among adults in sampled hospitals (Will et al., 2012). The study design in the article is cross-sectional research design using a sample of age, sex, and race of the patients. The sample size is 501 to 525 hospitals representing one percent of United States hospitalizations. The study uses stratified sampling with the sample characteristics being age, sex, and race of patients hospitalized of CHF in participating hospitals. Data was collected from the 1995 to 2009 National Hospital Discharge Survey (NHDS) conducted by the National Center for Health Statistics (Will et al., 2012). Data collection methods were entrance records by hospitals of the CHF patients admitted between 1995 and 2009. The procedures conducted were the removal of severe CHF patients to ensure the sample taken included that of patients whose hospitalization was preventable (Will et al., 2012). Data analysis involved weighting CHF hospitalization from 1995 to 2009 for the people above 18 and summation of numbers of three consecutive years to form 7 periods whose rates w ere calculated 100,000 of the population. Standardization, development of confidence intervals, Z-tests, and other statistical tests followed the analysis. The results depict increased rates of CHF hospitalization among all ages, and blacks have higher hospitalization rates than whites (Will et al., 2012). The strengths of the article are the in-depth data analysis and use of large sample data. The study limitations are non-reporting of 17% to 21% of the CHF hospitalizations and classification of people as multiracial from 2000 onwards. Another liability is the inability to exclude CHF hospitalizations occurring from transfers from other facilities (Will et al., 2012). Heart Failure in Hispanics is a qualitative research study done in the United States where the risk  factors, etiological conditions, diagnosis and treatment, and barriers to health care are done on Hispanic Patients.
