A Comparative Quantitative Analysis Of Admission Numbers

A comparative quantitative analysis of how many admissions at St

Conducting a comparative quantitative analysis of hospital admissions provides valuable insights into the operational dynamics and healthcare delivery effectiveness of major medical centers. This particular analysis focuses on two prominent hospitals in Minnesota—St. Mary's Hospital in Rochester and the University of Minnesota Medical Center in Minneapolis—using the 2012 Minnesota Hospitals Admissions by Care Unit Database. The core objective is to compare their respective admission patterns, with an emphasis on understanding whether St. Mary's Hospital experiences higher levels of acute care admissions relative to the University of Minnesota Medical Center.

Our hypothesis posits that St. Mary's Hospital has higher acute care admissions and overall hospital utilization than the University of Minnesota Medical Center. This premise is grounded in the hypothesis that due to its large capacity, specialized services, and affiliation with the Mayo Clinic, St. Mary's might attract a higher volume of acute care cases, especially in specialized units such as cardiology, neurology, and orthopedic care. Conversely, the University of Minnesota Medical Center, although sizable and comprehensive, might present different admission patterns due to its academic focus and broader distribution of outpatient services. The analysis will examine these differences quantitatively, leveraging the Minnesota State Hospital Database for 2012.

Literature Review

Understanding hospital admission patterns is an essential component of healthcare planning and policy development. Numerous studies have examined factors influencing hospital admissions, emphasizing hospital capacity, specialization, financial incentives, and demographic shifts. Kutcher and Evans (2013) highlighted how the shift towards outpatient care, driven by payer pressures, technological advances, and quality improvement initiatives, has altered the landscape of inpatient admissions. Hospitals that adapt by expanding outpatient services and specialty care tend to optimize patient throughput, reduce readmission rates, and improve financial performance.

Research on hospital utilization indicates that capacity and specialization significantly influence admission volumes. For instance, Roberts et al. (2014) established that larger hospitals with extensive specialization tend to attract more inpatient cases, particularly in areas such as cardiology, neurology, and orthopedics. Furthermore, demographic trends, notably the aging Baby Boomer generation, have increased demand for certain specialized services, prompting hospitals to expand these departments (Brennan et al., 2015). This shift has implications for hospital choice, patient outcomes, and healthcare costs.

Cross-sectional studies have employed statistical tools such as cross tabulation and chi-square tests to analyze relationships between hospital variables and patient admissions (Martz, 2012). These techniques enable researchers to reveal patterns, associations, and disparities across different healthcare settings, providing evidence-based guidance for hospital administrators and policymakers (Glynn et al., 2016). As the healthcare landscape continues to evolve, understanding these relationships through robust analysis remains critical.

Data Description

The data utilized for this analysis is sourced from the Minnesota Healthcare Cost Information System Hospital Annual Report, focusing on admissions at two Minnesota hospitals—St. Mary's Hospital in Rochester and the University of Minnesota Medical Center in Minneapolis—during the fiscal year 2012. The dataset captures detailed admission figures categorized by care units, covering acute and non-acute services. The data reflect hospital capacities, including licensed beds and bassinets, along with specific admission counts for various units such as medical-surgical, cardiac, neurological, neonatal, obstetric, orthopedic, and others.

St. Mary's Hospital is notably larger, with 1,700 licensed beds and a strong affiliation with Mayo Clinic. It reported a total of 40,615 acute care admissions, with high volumes in medical-surgical, orthopedics, and neurology units. The hospital's specialization and capacity contribute to its high inpatient volume, especially in complex and specialized care segments. In contrast, the University of Minnesota Medical Center had 1,265 licensed beds and recorded 34,416 acute care admissions. Its distribution across care units revealed different patterns—fewer admissions in some specialties but relatively higher in others like mental health and neonatal care, reflecting its academic and research focus.

Variables of Interest and Justification

The primary variables of interest in this analysis include the total number of admissions across specific care units—such as medical-surgical, cardiac, neurology, neonatal, obstetric, outpatient, and rehabilitation services—for both hospitals. Additionally, hospital-specific variables such as licensed beds, bassinets, and available beds were considered as subvariables. These variables allow us to measure and compare the capacity utilization and focus of each hospital, thereby revealing differences in service provision.

The choice of these variables is justified by their relevance to hospital functioning and patient care delivery. For example, high admission numbers in specialized units signal hospital expertise and capacity in those fields. Moreover, analyzing bed capacity and licensed resources contextualizes the admission figures, offering insights into operational efficiency and resource allocation. These variables collectively help evaluate hospital performance, patient volume, and the influence of hospital capacity on admission patterns.

Statistical Analysis Method

The primary statistical method employed for this analysis is cross-tabulation complemented by chi-square testing. Cross-tabulation is a fundamental statistical tool suitable for examining the relationships between categorical variables such as care units and hospital types. This method facilitates the creation of tables that display frequencies and percentages of admissions across different categories, thereby enabling visual assessment of differences and associations.

Using cross-tabulation allows us to compare admission counts systematically between St. Mary's and the University of Minnesota Medical Center. The chi-square test will then assess the statistical significance of observed differences, determining whether the variations in admission patterns are statistically meaningful or could have arisen by chance. By analyzing the p-values against significance levels (alpha), this approach will support objective conclusions about hospital utilization disparities.

This method's advantages lie in its simplicity, clarity, and appropriateness for categorical data. It provides an easy-to-interpret overview of hospital admission patterns, supports hypothesis testing, and helps identify meaningful differences or associations that can inform healthcare management strategies (Glynn et al., 2016). The combination of cross-tabulation and chi-square testing offers a robust framework for analyzing hospital data from the Minnesota database and drawing evidence-based inferences about hospital performance and utilization.

Conclusion

In conclusion, this analysis seeks to compare the inpatient admission patterns of St. Mary's Hospital and the University of Minnesota Medical Center using data from the 2012 Minnesota Hospitals Admissions by Care Unit Database. Our hypothesis that St. Mary's exhibits higher acute care admissions is grounded in its capacity, specialization, and affiliations. Employing cross-tabulation and chi-square tests will enable us to identify significant differences, offering insights into the operational efficacy of these hospitals. Such analyses are vital for healthcare planning, resource management, and policy formulation aimed at optimizing hospital services to meet growing demand, especially amid demographic shifts and technological advancements in healthcare delivery.
