Objective To assess the inpatient prevalence of osteoarthritis in a Midwestern state and to identify trends in demographics and hospital outcomes. Methods The Wisconsin State Inpatient Sample Database (2016) was queried to identify hospitalization records with a primary diagnosis of osteoarthritis. Bivariate correlation, descriptive statistics, and single-layer mean comparison were used for categorical and continuous data within the International Classification of Diseases, Tenth Revision, Clinical Modification (ICD-10-CM) sub-groups. Results In 2016, there were 64,805 admissions of osteoarthritis. The most common (>0.09%) were the right knee osteoarthritis (24.5%), left knee osteoarthritis (23%), right hip osteoarthritis (16.9%), left hip osteoarthritis (14.3%), knee unspecified osteoarthritis (11.5%), bilateral knees osteoarthritis (7%), and right shoulder osteoarthritis (2%). The mean age on admission was 67 years for each hip osteoarthritis, 66 years for each knee osteoarthritis, and 69 years for right shoulder osteoarthritis. The mean length of stay was 3.15 days for bilateral knee osteoarthritis and 1.92 days for the right shoulder osteoarthritis. Total inpatient charges and in-hospital mortality were highest in right shoulder osteoarthritis (USD 52,699.40 [0.6%]; N = 6), and total charges were lowest in right and left hip osteoarthritis (44,689.54 and 44,427.33, respectively). A greater frequency of females and Caucasians was consistently admitted within each of the included ICD-10-CM OA sub-groupings. Age was correlated with charge in the left hip osteoarthritis (r = 0.050) and right shoulder osteoarthritis (r = 0.068), and was negatively correlated with charge in the bilateral knee osteoarthritis (r = -0.115), right knee osteoarthritis (r = -0.054), and left knee osteoarthritis (r = -0.060). Conclusions In Wisconsin, with somewhat of a generalizability to other Midwestern states, attention should be given to Caucasian, elderly, and female patients with osteoarthritis of the hip and knee. Further studies are needed to broaden the understanding of cost utilization, how charges and hospital stay compare nationwide, and where preventative efforts are needed.
目的 评估美国中西部某州骨关节炎的住院患病率，并确定人口统计学特征及医院治疗结果的趋势。方法 检索威斯康星州住院患者样本数据库（2016年），以确定原发性诊断为骨关节炎的住院记录。对国际疾病分类第十次修订本临床修订版（ICD-10-CM）亚组内的分类数据和连续数据进行双变量相关性分析、描述性统计分析和单层均值比较。结果 2016年，有64805例骨关节炎住院病例。最常见的（>0.09%）是右膝骨关节炎（24.5%）、左膝骨关节炎（23%）、右髋骨关节炎（16.9%）、左髋骨关节炎（14.3%）、未明确部位的膝骨关节炎（11.5%）、双膝骨关节炎（7%）和右肩骨关节炎（2%）。各髋骨关节炎患者的入院平均年龄为67岁，各膝骨关节炎患者为66岁，右肩骨关节炎患者为69岁。双膝骨关节炎患者的平均住院时间为3.15天，右肩骨关节炎患者为1.92天。右肩骨关节炎患者的住院总费用和住院死亡率最高（52699.40美元[0.6%]；N = 6），左右髋骨关节炎患者的总费用最低（分别为44689.54美元和44427.33美元）。在纳入的每个ICD-10-CM骨关节炎亚组中，女性和白种人的入院频率一直较高。年龄与左髋骨关节炎（r = 0.050）和右肩骨关节炎（r = 0.068）的费用呈正相关，与双膝骨关节炎（r = -0.115）、右膝骨关节炎（r = -0.054）和左膝骨关节炎（r = -0.060）的费用呈负相关。结论 在威斯康星州，对其他中西部州有一定普适性结论，应关注患有髋部和膝部骨关节炎的白种人、老年人及女性患者。需要进一步开展研究，以加深对成本利用情况的理解，了解全国范围内费用和住院时间的比较情况，以及确定需要进行预防工作的领域。
