Thailand’s Universal Coverage Scheme (UCS) has improved healthcare access and utilization since its initial introduction in 2002. However, a substantial proportion of beneficiaries has utilized care outside the UCS boundaries. Because low utilization may be an indication of a policy gap between people’s health needs and the services available to them, we investigated the patterns of health-seeking behavior and their social/contextual determinants among UCS beneficiaries in the year 2013. The study findings from the outpatient analysis showed that the use of designated facilities for care was significantly higher in low-income, unemployed, and chronic status groups. The findings from the inpatient analysis showed that the use of designated facilities for care was significantly higher in the low-income, older, and female groups. Particularly, for the low-income group, we found that they (1) had greater health care needs, (2) received a larger number of services from designated facilities, and (3) paid the least for both inpatient and outpatient services. This pro-poor impact indicated that the UCS could adequately respond to beneficiaries’ needs in terms of vertical equity. However, we also found that a considerable proportion of beneficiaries utilized out-of-network services, which implied a lack of universal access to policy services from a horizontal equity point of view. Thus, the policy should continue expanding and diversifying its service benefits to strengthen horizontal equity. Particularly, private sector involvement for those who are employed as well as the increased unmet health needs of those in rural areas may be important policy priorities for that. Lastly, methodological issues such as severity adjustment and a detailed categorization of health-seeking behaviors need to be further considered for a better understanding of the policy impact.

To test a causal model of the impact of (a) nursing unit context on professional nursing practice; (b) professional practice on selected organizational (nurses' work satisfaction, nursing turnover, average length of patient stay) and patient outcomes (patient satisfaction, rate of reported medication errors, and falls); and (c) nursing unit context on these same organizational and patient outcomes. Professional nursing practice has been linked to positive outcomes for both nurses and patients. In contrast to other studies, this study focuses on professional nursing practice specifically at the nursing unit level, and uses a new analytic technique that permits examination of the simultaneous effects of professional nursing practice on both organizational and patient outcomes. Data were collected from 1682 registered nurses, and 1326 patients on 124 general medical-surgical nursing units in 64 general short-term acute care hospitals in the southeast. Multilevel structural equation modeling was used to analyze the data. We found that professional nursing practice had consistent effects across model levels on nursing satisfaction, but very limited effects on other outcomes. Important differences in the hospital- and nursing unit level models support continued use of multilevel modeling techniques in the study of organizational and patient outcomes.

To study the number of health information systems (HISs), applicable to administrative, clinical, and executive decision support functionalities, adopted by acute care hospitals and to examine how hospital market, organizational, and financial factors influence HIS adoption. A cross-sectional analysis was performed with 1441 hospitals selected from metropolitan statistical areas in the United States. Multiple data sources were merged. Six hypotheses were empirically tested by multiple regression analysis. HIS adoption was influenced by the hospital market, organizational, and financial factors. Larger, system-affiliated, and for-profit hospitals with more preferred provider organization contracts are more likely to adopt managerial information systems than their counterparts. Operating revenue is positively associated with HIS adoption. The study concludes that hospital organizational and financial factors influence on hospitals' strategic adoption of clinical, administrative, and managerial information systems.

The issues of medical errors and medical malpractice have stimulated significant interest in establishing transparency in health care, in other words, ensuring that medical professionals formally report medical errors and disclose related outcomes to patients and families. However, research has amply shown that transparency is not a universal practice among physicians. A review of the literature was carried out using the search terms "transparency," "patient safety," "disclosure," "medical error," "error reporting," "medical malpractice," "doctor-patient relationship," and "physician" to find articles describing physician barriers to transparency. The current literature underscores that a complex Web of factors influence physician reluctance to engage in transparency. Specifically, 4 domains of barriers emerged from this analysis: intrapersonal, interpersonal, institutional, and societal. Transparency initiatives will require vigorous, interdisciplinary efforts to address the systemic and pervasive nature of the problem. Several ethical and social-psychological barriers suggest that medical schools and hospitals should collaborate to establish continuity in education and ensure that knowledge acquired in early education is transferred into long-term learning. At the institutional level, practical and cultural barriers suggest the creation of supportive learning environments and private discussion forums where physicians can seek moral support in the aftermath of an error. To overcome resistance to culture transformation, incremental change should be considered, for example, replacing arcane transparency policies and complex reporting mechanisms with clear, user-friendly guidelines.
