Measuring hospital-wide activity volume for patient safety and infection control: a multi-centre study in Japan

<p>Abstract</p> <p>Background</p> <p>In Japan, as in many other countries, several quality and safety assurance measures have been implemented since the 1990's. This has occurred in spite of cost containment efforts. Although government and hospital decision-makers demand comprehensive analysis of these activities at the hospital-wide level, there have been few studies that actually quantify them. Therefore, the aims of this study were to measure hospital-wide activities for patient safety and infection control through a systematic framework, and to identify the incremental volume of these activities implemented over the last five years.</p> <p>Methods</p> <p>Using the conceptual framework of incremental activity corresponding to incremental cost, we defined the scope of patient safety and infection control activities. We then drafted a questionnaire to analyze these realms. After implementing the questionnaire, we conducted several in-person interviews with managers and other staff in charge of patient safety and infection control in seven acute care teaching hospitals in Japan.</p> <p>Results</p> <p>At most hospitals, nurses and clerical employees acted as the main figures in patient safety practices. The annual amount of activity ranged from 14,557 to 72,996 person-hours (per 100 beds: 6,240; per 100 staff: 3,323) across participant hospitals. Pharmacists performed more incremental activities than their proportional share. With respect to infection control activities, the annual volume ranged from 3,015 to 12,196 person-hours (per 100 beds: 1,141; per 100 staff: 613). For infection control, medical doctors and nurses tended to perform somewhat more of the duties relative to their share.</p> <p>Conclusion</p> <p>We developed a systematic framework to quantify hospital-wide activities for patient safety and infection control. We also assessed the incremental volume of these activities in Japanese hospitals under the reimbursement containment policy. Government and hospital decision makers can benefit from this type of analytic framework and its empirical findings.</p

Cost of hospital-wide activities to improve patient safety and infection control: A multi-centre study in Japan

Objective The aim of this study was to assess the financial costs to hospitals for the implementation of hospital-wide patient safety and infection control programs.Methods We conducted questionnaire surveys and structured interviews in seven acute-care teaching hospitals with an established reputation for their efforts towards improving patient safety. We defined the scope of patient safety activities by use of an incremental activity measure between 1999 and 2004. Hospital-wide incremental manpower, material, and financial resources to implement patient safety programs were measured.Results The total incremental activities were 19,414-78,540 person-hours per year. The estimated incremental costs of activities for patient safety and infection control were calculated as US$ 1.100-2.335 million per year, equivalent to the employment of 17-40 full-time healthcare staff. The ratio of estimated costs to total medical revenue ranged from 0.55% to 2.57%. Smaller hospitals tend to shoulder a higher burden compared to larger hospitals.Conclusions Our study provides a framework for measuring hospital-wide activities for patient safety. Study findings suggest that the total amount of resources is so great that cost-effective and evidence-based health policy is needed to assure the sustainability of hospital safety programs.

Evidence of the Association between Nurse Staffing Levels and Patient and Nurses&rsquo; Outcomes in Acute Care Hospitals across Japan: A Scoping Review

We aimed to summarize the evidence of an association between nurse staffing and nursing sensitivity outcomes in Japanese hospitals. A scoping review was conducted and reported following the PRISMA-SR 2020 statement. The ICHUSHI and CiNii databases were searched for published articles written in Japanese and PubMed and CINAHL for those written in English. Out of the 15 included studies, all observational studies, 3 were written in Japanese and the others in English. The nurse staffing level measures were grouped into three categories: patient-to-nurse ratio, nursing hours per patient day, and nurse-to-bed ratio. The outcome measures were grouped into three categories: patient outcome, nursing care quality reported by nurses, and nurse outcome/nursing care quality. Some studies reported that the nursing staff increasingly favored positive patient outcome. Conversely, the findings regarding failure to rescue, in-hospital fracture, and post-operative complications were inconsistent. Although some studies indicated that more nurse staffing was favored toward better patient and nurse outcomes, due to the sparse accumulation of studies and heterogeneity among the findings, it is difficult to draw robust conclusions between nurse staffing level and outcomes in Japanese acute care hospitals

Factors associated with system-level activities for patient safety and infection control

Objective We examined the relationship between hospital structural characteristics and system-level activities for patient safety and infection control, for use in designing an incentive structure to promote patient safety.Methods This study utilized a questionnaire to collect institutional data about hospital infrastructure and volume of patient safety activities from all 1039 teaching hospitals in Japan. The patient safety activities were focused on meetings and conferences, internal audits, staff education and training, incident reporting and infection surveillance. Generalized linear modeling was used.Results Of the 1039 hospitals surveyed, 418 (40.2%) hospitals participated. The amount of activities significantly increased by over 30% in hospitals with dedicated patient safety and infection control full-time staff (P Safety management Infection control Health resources Health policy

Healthcare costs for the elderly in Japan: Analysis of medical care and long-term care claim records.

The population is aging rapidly in many developed countries. Such countries need to respond to the growing demand and expanding costs of healthcare (HC) for the elderly. Therefore, it is important to investigate the factors correlating such HC costs. In Japan, HC is composed of two sections, namely medical care (MC) and long-term care (LTC). While many studies have examined MC and LTC costs on their own, few studies have conducted comprehensive investigations of HC costs. The aim of this study is to examine the risk factors that influence HC costs for the elderly who enroll in the LTC insurance system in Japan.The inclusion criteria in the present study are as follows: being 65 years of age, or older; certified eligibility for, and use of services offered by the LTC insurance system at home or in an institutional setting in December 2009; and being covered by the National Health Insurance (NHI) system. MC and LTC insurance data were obtained from claim records for the elderly in July and December of 2007, 2008, and 2009 (i.e., a total of six survey points). Panel data, per subject, were constructed using MC and LTC claim records. The sample included 810 subjects and 4029 observations.We estimated a regression equation with a censored dependent variable using a Tobit model. Significant associations between MC or LTC costs and interaction terms (household composition × seasonal effects) were investigated. MC costs significantly decreased and LTC costs significantly increased among subjects living alone during winter. Income level was also a positive determinant of MC costs, while eligibility level was a positive determinant of LTC costs.We recommend that the health policy for the elderly focus more on seasonal effects, household composition, and income level, as well as on eligibility level
