Gifts, bribes and solicitions: print media and the social construction of informal payments to doctors in Taiwan.

The Taiwanese practice of patients giving informal payments to physicians to secure services is deeply rooted in social and cultural factors. This study examines the portrayal of informal payments by Taiwanese print news media over a period of 12 years-from prior to until after the implementation of national health insurance (NHI) in Taiwan in 1995. The goal of the study was to examine how the advent of NHI changed the rationale for and use of informal payments. Both before and after the introduction of NHI, Taiwanese newspapers portrayed informal payments as appropriate means to secure access to better health care. Newspaper accounts established that, although NHI reduced patients' financial barriers to care, it did not change deeply held cultural beliefs that good care depended on the development of a reciprocal sense of obligation between patients and physicians. Physicians may have also encouraged the ongoing use of informal payments to make up revenue lost when NHI standardized fees and limited income from dispensing medications. In 2002, seven years after the implementation of NHI, the use of informal payments, though illegal, was still being justified in the print media through allusions to its role in traditional Taiwanese culture.

How will we know patients are safer? An organization-wide approach to measuring and improving safety.

OBJECTIVE: Our institution, like many, is struggling to develop measures that answer the question, How do we know we are safer? Our objectives are to present a framework to evaluate performance in patient safety and describe how we applied this model in intensive care units. DESIGN: We focus on measures of safety rather than broader measures of quality. The measures will allow health care organizations to evaluate whether they are safer now than in the past by answering the following questions: How often do we harm patients? How often do patients receive the appropriate interventions? How do we know we learned from defects? How well have we created a culture of safety? The first two measures are rate based, whereas the latter two are qualitative. To improve care within institutions, caregivers must be engaged, must participate in the selection and development of measures, and must receive feedback regarding their performance. The following attributes should be considered when evaluating potential safety measures: Measures must be important to the organization, must be valid (represent what they intend to measure), must be reliable (produce similar results when used repeatedly), must be feasible (affordable to collect data), must be usable for the people expected to employ the data to improve safety, and must have universal applicability within the entire institution. SETTING: Health care institutions. RESULTS: Health care currently lacks a robust safety score card. We developed four aggregate measures of patient safety and present how we applied them to intensive care units in an academic medical center. The same measures are being applied to nearly 200 intensive care units as part of ongoing collaborative projects. The measures include how often do we harm patients, how often do we do what we should (i.e., use evidence-based medicine), how do we know we learned from mistakes, and how well do we improve culture. Measures collected by different departments can then be aggregated to provide a hospital level safety score card. CONCLUSION: The science of measuring patient safety is immature. This article is a starting point for developing feasible and scientifically sound approaches to measure safety within an institution. Institutions will need to find a balance between measures that are scientifically sound, affordable, usable, and easily applied across the institution.

Antibiotic prescribing by ambulatory care physicians for adults with nasopharyngitis, URIs, and acute bronchitis in Taiwan: a multi-level modeling approach.

BACKGROUND: Imprudent prescribing of antibiotics in ambulatory care in Asia is of great concern. However, an adequate understanding of factors associated with antibiotic prescribing patterns in Asia has not been achieved. OBJECTIVE: Our aim was to identify patient and physician characteristics that influence antibiotic prescribing for adults with nasopharyngitis (common colds), upper respiratory tract infections (URIs) or bronchitis in Taiwan. METHODS: Generalized Estimating Equations (GEE) were used to analyze all 128,260 episodes of common colds, URIs and bronchitis generated by a random sample of 137,935 adult National Health Insurance (NHI) beneficiaries (> or = 18 years old) in Taiwan in 2000. RESULTS: Multivariate analysis results revealed substantial variations across different physician groups. Physician age and accreditation level of the physician's practice setting were the characteristics most associated with prescribing of antibiotics at the initial encounters for these episodes of care. Urban practising physicians (adjusted OR 1.69, 95% CI 1.29-2.21) and those who were self-dispensing or with on-site pharmacists (adjusted OR 1.32, 95% CI 1.19-1.46) were also higher prescribers of antibiotics for adults. Other significant physician predictors included physician specialty, patient volume, and ownership of practice setting. CONCLUSIONS: Results suggest that both accessibility to updated medical information and economic incentives of the attending physician may shape prescribing of antibiotics in ambulatory care in Taiwan. Interventions should be developed to influence these modifiable factors to reduce antibiotic prescriptions of questionable value.

Integrating the intensive care unit safety reporting system with existing incident reporting systems.

BACKGROUND: Voluntary incident reporting systems that identify risks can be integrated into existing hospital reporting systems and can improve patient safety. FINDINGS: A voluntary and anonymous Web-based intensive care unit safety reporting system (ICUSRS) was implemented in a cohort of intensive care units (ICUs). The reporting system was integrated into hospitals' reporting systems after the adverse event reporting structures were investigated. Reporting systems were classified as mandatory or voluntary and internal or external; the extent of formal training was identified and the trajectory of completed adverse events in the exisiting systems were tracked. Information from reported incidents was sent back monthly to the hospital ICUs through case discussions and a quarterly newsletter. RESULTS: All seven hospitals had internal reporting systems and two also used external reporting systems. In general, the majority of incident reports were completed by registered nurses and were reported to the nursing chain of command. Many of the sites had little knowledge or understanding of their existing reporting systems. CONCLUSION: Voluntary external reporting systems such as the ICUSRS hold promise for improving patient safety.

Critical pathway effectiveness: assessing the impact of patient, hospital care, and pathway characteristics using qualitative comparative analysis.

OBJECTIVE: To qualitatively describe patient, hospital care, and critical pathway characteristics that may be associated with pathway effectiveness in reducing length of stay. DATA SOURCES/STUDY SETTING: Administrative data and review of pathway documentation and a sample of medical records for each of 26 surgical critical pathways in a tertiary care center's department of surgery, 1988-1998. STUDY DESIGN: Retrospective qualitative study. DATA COLLECTION/ABSTRACTION METHODS: Using information from a literature review and consultation with experts, we developed a list of characteristics that might impact critical pathway effectiveness. We used hypothesis-driven qualitative comparative analysis to describe key primary and secondary characteristics that might differentiate effective from ineffective critical pathways. PRINCIPAL FINDINGS: " All 7 of the 26 pathways associated with a reduced length of stay had at least one of the following characteristics: (1) no preexisting trend toward lower length of stay for the procedure (71 percent), and/or (2) it was the first pathway implemented in its surgical service (71 percent). In addition, pathways effective in reducing length of stay tended to be for procedures with lower patient severity of illness, as indicated by fewer intensive care days and lower mortality. Effective pathways tended to be used more frequently than ineffective pathways (77 versus 59 percent of medical records with pathway documents present), but high rates of documented pathway use were not necessary for pathway effectiveness. CONCLUSIONS: Critical pathway programs may have limited effectiveness, and may be effective only in certain situations. Because pathway utilization was not a strong predictor of pathway effectiveness, the mechanism by which critical pathways may reduce length of stay is unclear.

Antibiotic prescribing for children with nasopharyngitis (common colds), upper respiratory infections, and bronchitis who have health-professional parents.

OBJECTIVE: Antibiotic resistance might be reduced if patients could be better informed regarding the lack of benefits of antibiotics for children with viral infections and avoid antibiotic prescriptions in these circumstances. This study investigated whether children having health professionals as parents, a group whose parents are expected to have more medical knowledge and expertise, are less likely than other children to receive antibiotics for nasopharyngitis (common colds), upper respiratory tract infections (URIs), and acute bronchitis. METHODS: Retrospective analyses were conducted by using National Health Insurance data for children of physicians, nurses, pharmacists, and non-health personnel, who had visited hospital outpatient departments or physician clinics for common colds, URIs, and acute bronchitis in Taiwan in 2000. A total of 53733 episodes of care for common colds, URIs, and acute bronchitis in a nationally representative sample of children (aged < or =18 years) living in nonremote areas were analyzed. RESULTS: The study found that, after adjusting for characteristics of the children (demographic, socioeconomic, and health status) and the treating physicians (demographic, practice style, and setting), children with a physician (odds ratio [OR]: 0.50; 95% confidence interval [CI]: 0.36-0.68) or a pharmacist (OR: 0.69; 95% CI: 0.52-0.91) as a parent were significantly less likely than other children to receive antibiotic prescriptions. The likelihood of receiving an antibiotic for the children of nurses (OR: 0.91; 95% CI: 0.77-1.09) was similar to that for children in the comparison group. CONCLUSIONS: This finding supports our hypothesis that better parental education does help to reduce the frequency of injudicious antibiotic prescribing. Medical knowledge alone, however, may not fully reduce the overuse of antibiotics. Physician-parents, the expected medically savvy parents, can serve as a benchmark for the improvement potentially achievable in Taiwan through a combination of educational, regulatory, communication, and policy efforts targeted at more appropriate antibiotic prescribing in ambulatory settings.

Are critical pathways effective for reducing postoperative length of stay?

BACKGROUND: Many hospitals use critical pathways to attempt to reduce postoperative length of stay (PLOS) for diverse conditions and procedures. OBJECTIVE: To evaluate whether critical pathways were associated with reductions in postoperative PLOS after accounting for prepathway trends in PLOS. RESEARCH DESIGN: Retrospective cohort study, from 1988 to 1998. SETTING: Academic medical center department of surgery. SUBJECTS: A total of 10,960 admissions eligible for 1 of 26 critical pathways implemented from 1990 to 1996, from 2 years before to 2 years after each pathway implementation date. Coding definitions were developed and validated to identify admissions eligible for each pathway, and data were abstracted from the hospital's discharge database. MEASURE: A pathway was considered effective if, after its implementation, there was a statistically significant decrease in the prepathway trend for PLOS. RESULTS: Median number of annual eligible admissions per pathway was 59 (range, 18-706). Median PLOS for the prepathway periods was 8 days (interquartile range, 5-10 days). For 16 (62%) pathways, PLOS was already declining in the prepathway period. After adjusting for demographics, comorbidity, admission characteristics, and prepathway time trends in PLOS, 7 (27%) pathways were associated with a significant postimplementation decrease in the rate of change in PLOS (range among the 7 pathways, 5-45% decrease) and none with a significant increase from the prepathway trend for PLOS. CONCLUSION: Critical pathways may decrease postoperative stay for some, but not all, surgeries. Trends toward decreasing length of stay over time may reduce the impact of critical pathways on this outcome.

Building safety into ICU care.

The Institute of Medicine's (IOMs) report, "To Err is Human," recently addressed patient safety in the United States, alerting the nation to the need for improved systems of health care. Seven main findings were addressed in this report, we focus on 3: (1) patient safety is a nationwide problem, (2) health care workers are not to blame, and (3) safety and harm are products of care systems. This article discusses systems in intensive care units (ICUs) and how these systems affect patient safety. We use a case example to outline the complex chain of medical and administrative system failures that can result in an adverse event. Then we discuss evidence linking ICU organizational characteristics with patient safety, focusing on how safer systems in ICUs can directly improve patient care.

ICU incident reporting systems.

Intensive care is one of the largest and most expensive components of American health care. Studies suggest that errors and resulting adverse events are common in intensive care units (ICUs). The incidence may be as high as 2 errors per patient per day; 1 in 5 ICU patients may sustain a serious adverse event, and virtually all are exposed to serious risk for harm. Theories of error developed in aviation and other high-risk industries suggest that errors are likely to occur in all complex systems. Reporting of incidents, including both adverse events and near misses, is an essential component for improving safety. Voluntary, confidential reporting is likely to be more important than mandatory reporting. There have been a few efforts to apply such systems in medicine. In intensive care, the Australian Incident Monitoring System (AIMS)-ICU has been the most prominent. We have designed a Web-based ICU Safety Reporting System (ICUSRS). The goal is to identify high-risk situations and working conditions, to help change systems, and reduce the risk for error. The analysis and feedback of reports will inform the design of interventions to improve patient safety. The effort is aided substantially by collaboration with the 30 participating ICUs and important stakeholders including the Society of Critical Care Medicine, the American Society for Health-care Risk Management, the Food and Drug Administration Center for Devices and Radiological Health, the Foundation for Accountability, and the Leapfrog Group. A demonstration and evaluation of the system is underway, funded by the Agency for Healthcare Re-search and Quality.

Relationship between performance measurement and accreditation: implications for quality of care and patient safety.

This study examined the association between the Joint Commission on Accreditation of Healthcare Organizations (JCAHO) accreditation scores and the Agency for Healthcare Research and Quality's Inpatient Quality Indicators and Patient Safety Indicators (IQIs/PSIs). JCAHO accreditation data from 1997 to 1999 were matched with institutional IQI/PSI performance from 24 states in the Healthcare Cost and Utilization Project. Most institutions scored high on JCAHO measures despite IQI/PSI performance variation with no significant relationship between them. Principal component analysis found 1 factor each of the IQIs/PSIs that explained the majority of variance on the IQIs/PSIs. Worse performance on the PSI factor was associated with worse performance on JCAHO scores (P=.02). No significant relationships existed between JCAHO categorical accreditation decisions and IQI/PSI performance. Few relationships exist between JCAHO scores and IQI/PSI performance. There is a need to continuously reevaluate all measurement tools to ensure they are providing the public with reliable, consistent information about health care quality and safety.
