Abstract Background This study examined the association between parenteral energy/amino acid doses and in-hospital mortality among inpatients on long-term nil per os (NPO) status, using a medical claims database in Japan. Methods Hospitalized patients with aspiration pneumonia, aged ≥65 years and on >7-days NPO status, were identified in a medical claims database between January 2013 and December 2018. Using multivariate logistic regression and regression analyses, we examined the association between mean parenteral energy/amino acid doses and in-hospital mortality, and secondarily the association between prognosis (in-hospital mortality, inability to receive full oral intake, re-admission, hospital stay length) among four groups classified by mean amino acid dose (No dose: 0 g/kg/day; Very low dose: >0, ≤0.3 g/kg/day; Low dose: >0.3, ≤0.6 g/kg/day; Moderate dose: >0.6 g/kg/day). Results The analysis population included 20,457 inpatients (≥80 years: 78.3%). In total, 5,920 mortalities were recorded. Increased amino acid doses were significantly associated with reduced in-hospital mortality (p <0.001). With a No dose reference level, the odds ratios (95% confidence interval) of in-hospital mortality adjusted for potential confounders, were 0.78 (0.72–0.85), 0.74 (0.67–0.82), and 0.69 (0.59–0.81) for Very low, Low, and Moderate amino acid doses, respectively. Additionally, patients prescribed amino acid dose levels >0.6 g/kg/day had shorter hospitalization periods than those prescribed none. Conclusions Increased amino acid doses were associated with reduced in-hospital mortality. Sufficient amino acid administration is recommended for patients with aspiration pneumonia requiring NPO status.

Purpose The purpose of this paper is to determine the characteristics of healthcare facilities that produce the most efficient inpatient orthopedic surgery using a large-scale medical claims database in Japan. Design/methodology/approach Reimbursement claims data were obtained from April 1 through September 30, 2014. Input-oriented Banker-Charnes-Cooper model of data envelopment analysis (DEA) was employed. The decision-making unit was defined as a healthcare facility where orthopedic surgery was performed. Inputs were defined as the length of stay, the number of beds, and the total costs of expensive surgical devices. Output was defined as total surgical fees for each surgery. Efficiency scores of healthcare facilities were compared among different categories of healthcare facilities. Findings The efficiency scores of healthcare facilities with a diagnosis-procedure combination (DPC) reimbursement were significantly lower than those without DPC (p=0.0000). All the efficiency scores of clinics with beds were 1. Their efficiency scores were significantly higher than those of university hospitals, public hospitals, and other hospitals (p=0.0000). Originality/value This is the first research that applied DEA for orthopedic surgery in Japan. The healthcare facilities with DPC reimbursement were less efficient than those without DPC. The clinics with beds were the most efficient among all types of management bodies of healthcare facilities.
