Re-engineering the medication error-reporting process: removing the blame and improving the system.

A hospital's change from a traditional, multitiered incident-reporting system for medication errors to a standardized, nonpunitive medication-use variance process is described. After weaknesses were identified in the hospital's system for reporting and evaluating medication errors, a multidisciplinary task force was formed to redesign the hospital's medication error-reporting system. Its guiding principles were as follows: anonymity and freedom from punitive action are essential for increasing the number of reports, rating medication errors facilitates identification of areas for system improvement, potential errors provide valuable insight into the system's vulnerabilities, and timely review of reports enables rapid systematic correction. To support the intended nonpunitive culture, the term medication-use variance was used in lieu of medication error for any unplanned event that deviates from the intended course of prescribing, dispensing, administering, or monitoring medications. A one-page medication-use variance report was developed that prompted the reporter for key data elements, including root causes, patient outcomes, and possible ways to prevent similar incidents. The most difficult decision for the task force was deciding whether the process should be anonymous. After getting the support of the medical-legal counsel and the quality improvement department for an anonymous reporting process, the task force agreed to test it in the department of pharmacy and in three patient units in September 1998. A paper-driven reporting process was selected initially because an electronic system would not be truly anonymous. The number of reports from these units increased compared with historical trends, and for the first time potential errors were reported. The report form was easy to use and improved the interpretation of reports. Despite these positive results, task force members remained divided on the issue of anonymity but ultimately embraced the nonpunitive culture. In the first six months following hospitalwide implementation, the number of events captured increased more than fivefold; it continues to increase. The resulting database serves as a trigger for quality improvement efforts and a measure of their effectiveness. The redesign of the medication error-reporting process served as the impetus for a change in the organizational culture surrounding medication errors.

The Ontario HIV seroprevalence study of childbearing women: results from the first year of testing.

The Ontario HIV Seroprevalence Study of Childbearing Women is an unliked anonymous seroprevalence study designed according to the well-established ethical and legal guidelines for such studies. Commencing in November, 1989, randomly selected neonatal heelprick specimens were tested for the presence of HIV antibodies after all identifying information had been permanently and irrevocably unlinked from the specimens. During the first year of the study 94,119 (approximately 60% of all submitted specimens) were tested. Twenty-six specimens which were repeatedly reactive by EIA were confirmed as positive for an overall crude seroprevalence rate of 2.8 per 10,000 women having live births (95% CI: 1.8-4.1). Twenty-five of the 26 confirmed seropositive results came from babies born in hospitals in the Metropolitan Toronto, Ottawa-Carlton, or Hamilton-Peel-Halton regions.

Is it possible to use the hypoosmotic swelling test as criteria for "freezeability" of human semen in an AID program?

The aim of this study was to determine the possibility of the introduction of another parameter--the hypoosmotic swelling test--in the evaluation of the freezing potentially of anonymous donor's semen sample to be utilized in an AID program. 154 donor semen samples were frozen using classic seminal parameters: HOS tests were performed but not utilized as criteria for freezeability. All specimens were thawed and another HOS test was performed. All specimens were divided into two groups on the basis of the pre freezing HOS test value--HOS tests positive (> or = 55%) and HOS test negative (< 55%)--to verify if it's possible to correlate this value to the recovery of a good motility after thawing. A further division was performed: HOS tests highly positive (> or = 70%), HOS positive (60-55%) and HOS tests negative (< 55%) but the authors did not find any statistical difference. As concerns the clinical evaluation, were considered the last 15 pregnancies achieved with 11 samples out of 22 utilized. There was not any statistical difference. The data could seem to confirm the hypothesis that it is not possible to utilize the HOS test as a predictive value of "freezeability" of human semen sample.

Teaching resuscitation to pediatric residents: the effects of an intervention.

OBJECTIVE: To evaluate the effectiveness of an educational intervention on pediatric residents' resuscitation fund of knowledge, technical skills, confidence, and overall performance. DESIGN: Prospective, nonconcurrent, controlled interventional trial. SETTING: Urban pediatric tertiary care hospital. PARTICIPANTS: An intervention group (IG) of 28 pediatric residents graduating in 1997, and a control group (CG) of 30 pediatric residents graduating in 1996. INTERVENTIONS: Resuscitation course with didactic lectures and skills practice stations, as well as a minimum of 3 practice mock resuscitations with immediate feedback throughout postgraduate year 3. MAIN OUTCOME MEASURES: Fund of knowledge, using the Pediatric Advanced Life Support test and short answer test; technical skills, using the Airway and Vascular Access Skills Assessment; experience and confidence, using an anonymous survey; and overall performance, evaluated using a videotaped mock resuscitation test. RESULTS: The IG scored better on the short answer test (P<.001). A larger number of IG residents were successful in the completion of ancillary airway maneuvers and femoral vascular access (P =.02), as well as endotracheal intubation (P =.004) and intraosseous access (P =.002). The IG was more confident in their leadership role (P =.0001) and technical skills (P =.05). Trends toward improved overall performance were noted for the IG mock resuscitations. Residents in the IG were more likely to assess the airway in fewer than 2 minutes (P =.02), recognize the threat to life in fewer than 5 minutes (P =.02), and complete the primary survey in a timely fashion (P =.05). They required fewer prompts (P =.04) and made fewer mistakes (P =.07). CONCLUSIONS: A structured, formal curriculum can improve the necessary fund of knowledge, skills, confidence, and leadership required for resuscitation.

Voluntary anonymous linked study of the prevalence of HIV infection and hepatitis C among inmates in a Canadian federal penitentiary for women.

OBJECTIVE: To determine the seroprevalence of HIV infection and hepatitis C among inmates of a federal penitentiary for women. DESIGN: Voluntary, anonymous, linked, point-prevalence study involving testing of blood samples for antibodies to HIV and hepatitis C virus. PARTICIPANTS: All inmates of the multilevel security federal Prison for Women, Kingston, Ont., who volunteered to participate in the study. Inmates at this long-stay facility are from across Canada. OUTCOME MEASURE: Seroprevalence rate among participants of antibodies to HIV and hepatitis C virus. RESULTS: Of the 130 inmates available for study 113 (86.9%) agreed to donate a blood sample. One woman (0.9%) was HIV positive; 45 (39.8%) were positive for hepatitis C antibody. CONCLUSIONS: It is possible to obtain a high participation rate in a voluntary, anonymous, linked point-prevalence study in a long-stay penitentiary. The HIV seroprevalence rate of 0.9% is lower than that found in studies in provincial (short-stay) prisons. However, the high rate of antibodies to hepatitis C suggests a significant level of risk behaviour, most likely injection drug use, and suggests the potential for a rapid increase in the rate of HIV infection should the number of newly admitted HIV-positive inmates who use injection drugs rise.

Screening of substance misuse during early pregnancy in Blyth: an anonymous unlinked study.

Substance abuse during pregnancy is rising and often remains undiagnosed. This harms both the mother and the baby. We conducted an anonymous unlinked study in Blyth valley, Northumberland, to determine the prevalence of substance abuse and alcohol use during pregnancy. Urine toxicology screening was performed on 150 women who attended antenatal clinic for booking. Seven commonly misused substances (amphetamine, benzodiazepine, barbiturates, cannabinoids, cocaine, methadone and opiates) and alcohol were tested in the urine. A total of 16 (10.7%) women were found positive and all 16 of them had denied use of any substance. Amphetamine was the most common among the substances misused. A total of 12 out of the 16 were from social classes 4 and 5. None of the positive women was nulliparous. Because of the difficulty in identifying substance misuse in pregnant women, consideration should be given to the implementation of routine substance screening at the booking antenatal visit in general population with a high incidence of substance misuse.

Venereal disease control among homosexuals; An outreach program.

With the support and participation of area homosexual organizations and a local bar, the City Health Department developed an outreach/education/screening program for venereal disease (VD) control. Venereal disease education and blood testing were conducted during four sequential Wednesday evenings in the bar on a volunteer basis, anonymously if requested. Of the 118 sera drawn, ten were reactive on serologic testing. Two of these reactive blood tests led to the discovery of two new cases of primary syphiles. No cultures were positive for Neisseria gonorrhoeae. The subject response rate confirms the value of an anonymous reporting method; the discovery of two cases of primary syphilis lends credence to case finding by field-screening a high-risk population.

HIV antibody testing of gay men in smaller US cities.

The incidence of new AIDS diagnoses among gay males indicates that risk reduction in smaller communities may be lagging behind that reported in larger cities. Contradictory evidence exists, largely from urban areas, concerning the utility of HIV testing as a means of promoting behavioural change. This study examined the relationship between HIV antibody testing and subsequent high-risk sexual behaviours among gay men in cities of 180,000 or fewer inhabitants. In February and March of 1992, male gay bar patrons in sixteen small US cities were administered an anonymous questionnaire concerning recent sexual behaviour and HIV testing history. Of the 1820 respondents, 28.1% had recently engaged in unprotected anal intercourse and 60.7% had been tested for HIV antibodies. Those who had been tested were more sexually active and reported more protected and safer sexual activities. Analyses at the individual and city levels converged to demonstrate that communities as well as individuals evidence increased self-protection in association with HIV antibody testing.

Case-control study of leukemia and diagnostic radiation exposure.

A case-control study of leukemia and diagnostic X-ray exposure was conducted by a multi-institution co-operative study group. The subjects were 134 patients with acute myelogenous leukemia, 57 with chronic myelogenous leukemia, 56 with acute lymphocytic leukemia and 50 with myelodysplasia syndrome, who were between 15 and 79 years old, and diagnosed at one of 27 hospitals between September 1993 and August 1995. The controls were 479 first-visit patients seen at eight of these 27 hospitals. History of diagnostic X-ray tests between 1982 and 1991 was determined by an anonymous self-administered questionnaire. The total relative dose of radiation exposure was calculated by summing the products of given weights and frequencies of each test. The relative risk was 0.83 (95% confidence interval (C.I.), 0.58-1.19) for relative dose of 10-30 (equivalent to 4-11 times of UGI series), 0.76 (0.48-1.20) for relative dose of 30 or more (more than 12 times of UGI series), when compared with relative dose of 0-10 (0-3 times of UGI series). Analysis according to type of leukemia revealed that only acute myelogenous leukemia had an estimated relative risk above unity (1.08, 95% C.I. 0.69-1.69, for relative dose 10-30). This study did not support the hypothesis that diagnostic X-ray tests increases leukemia risk.

[Clinical risk management. Implementation of an anonymous error registration system in the anesthesia department of a university hospital].

BACKGROUND: The main goal of a medical risk management system is reduction of treatment errors and the primary focus is patient safety. MATERIALS AND METHODS: A task force on risk management in anaesthesia was established in the department of Anaesthesiology and Intensive Care at the University Hospital Dresden with the aim to implement a critical incident reporting system (CIRS) followed by a structured analysis. The theoretical basic principles and tools for the incident analysis are presented. RESULTS: The task force developed a machine-readable, structured, anonymous questionnaire, which was implemented in clinical practice after a primary test period. CONCLUSIONS: Prerequisites for the implementation of an effective CIRS are support from the department head, anonymity, independence of the task force from the department head and competence of the task force to initiate changes and improvements. CIRS is a powerful tool to register and analyse critical incidents and may influence the following domains: education and training (human factors), medical equipment (technical factors), quality of working processes and departmental communication (organisational factors).

Counseling lesbian patients about getting pregnant.

OBJECTIVE: To describe an approach to counseling lesbian patients about getting pregnant. SOURCES OF INFORMATION: Information in this paper is based on evidence from randomized controlled trials (level I evidence), non-randomized trials (level II evidence), expert opinion (level III evidence), and government regulations. MAIN MESSAGE: We review 5 steps that comprise an approach to counseling lesbian patients about getting pregnant safely and efficiently. These steps are preconception care (including counseling, testing, and immunization); donor choice (including explaining the risks and benefits of choosing between a known or anonymous donor and the difference between fresh and frozen semen); donor testing (including Health Canada's requirements for semen processing and recommendations for testing before home insemination); ordering the semen (including information about sperm banks and the need for "Canadian compliant" semen); and the insemination process (including techniques for monitoring ovulation and various methods of insemination). CONCLUSION: Primary care physicians can help lesbians achieve pregnancy by providing education, testing, referrals, and insemination services.

[Client anxiety from awareness of personal HIV risk and relation to taking HIV test at public health centers in Japan].

Clients taking HIV antibody tests at public health centers (PHCs) in Japan were surveyed in autumn of 1995 centered on 17 PHCs selected by a snow-ball sampling method in domestic PHCs. The anonymous self-administered questionnaires were given out by PHC's medical doctors or public health nurses after receiving informed consent of this survey's objectives following HIV post-test counseling. A total of 250 questionnaires were collected (71.8%). Valid questionnaires were 233 (67.0%) and 62.7% (146 people) were male, 37.3% (87 people) were female, with differences in mean age by sex being significant (p < .001). The greatest motivating factor for getting HIV testing was concerning secondary infection to partners and extreme anxiety relating to one's own possible infection. This motivating factor was greater than having experienced previous HIV infectious high-risk behavior (i.e. condomless sex). Repeat (more than twice) visitors totaled 49 (21.0%), with 75% having experienced HIV infectious high-risk behavior since the last HIV test. "Having being advised or having received from partners or friends" affected decision making to get tested. About half of subjects vacillated before coming to the PHC for taking anonymous the HIV antibody test. Through multiple-logistic regression analysis factors causing vacillation were: greater self-awareness of possibility of having HIV infection and the fact that HIV infected people must retire from their work (or studies) despite their current health condition being fine. While HIV medical/clinical treatment progress continues, the stigma toward HIV/AIDS and the resulting discrimination is not changing in terms of the general citizen's knowledge and attitudes. This result will likely curtail HIV antibody testing behavior.

Meconium testing for cocaine metabolite: prevalence, perceptions, and pitfalls.

OBJECTIVES: We determined the prevalence of prenatal cocaine use in a racially mixed sample of urban and suburban mothers and correlated its use with maternal demographics and newborn measurements. STUDY DESIGN: Meconium from 621 consecutive newborns delivered at two university-affiliated urban hospitals were assayed for benzoylecgonine. Maternal and infant characteristics were linked anonymously with the results. Statistical analysis included t test, Fisher's exact test, Duncan's multiple range analysis, and analysis of covariance, with a value of p < 0.05 considered significant. RESULTS: We found that 3.4% of meconium samples had benzoylecgonine levels exceeding 0.1 micrograms/ml. Its presence was statistically correlated with maternal and neonatal characteristics. A nurse's opinion of cocaine use was correct 22% of the time. CONCLUSIONS: Prenatal cocaine use was statistically associated with multiparity, multigravidity, late-onset and clinic-based prenatal care, public assistance, nonwhite race, and low academic achievement. A nurse's opinion was a poor predictor of maternal cocaine use. Cocaine-exposed infants were significantly smaller, and this correlated best with nonwhite background.

[Huntington disease. Current state of research].

Huntington's disease is a hereditary disease with autosomal dominant transmission which generally occurs in adults. The gene was discovered in 1983 and the genetic abnormality in March 1993. The most commonly recognized clinical manifestation is choreiform movements although other signs often appear more invalidating to family and friends. Cognitive decline, modifications in behaviour, and sometimes psychiatric disturbances are perceived as the major handicap in everyday life. In this review, emphasis has been placed on late onset forms of the disease. Recent research has focused on morphologic and functional imagery, the neuropathologic stages of selective neurone loss beginning in the striatum, and the role of excitotoxic amino-acids. Certain ethical considerations must be addressed when determining prognosis. Predictive tests and follow-up must be prepared and conducted scrupulously and proposed to voluntary, informed, major subjects at risk. Tests should be performed by a qualified laboratory working on anonymous samples, independent of the clinical team, and should be given to the subject orally by a genetic counsellor. A prenatal test may be requested by parents at risk. The question of treatment, which to date can only offer symptomatic relief, should be re-addressed in light of the recent discovery of the mutation published in March 1993.

[Estimate of the prevalence of tuberculosis infection among vaccinated school-children by the Bhattacharya's method].

The successful application of Bhattacharya's method (decomposition of frequency distribution into normal components by a graphic method) in the analysis of the results of tuberculin test performed on a population sensitized by "anonymous" strains of mycobacteria, suggested the possibility of its application to two samples of BCG vaccinated school-children, living in the city of S. Paulo (Brazil). One of the sample groups, vaccinated between the second and seventh years of life, was surveyed in 1982 and the other, vaccinated during the first year of life, was surveyed in 1988. In both populations it was possible to characterize the normal component corresponding to children infected by tuberculous bacilli and to quantify them. In the first one, the average size of the reactions was 17.40 mm, the standard deviation 3.72 mm and the proportion of infected children 7.71%, against 4.85% in the unvaccinated control group; otherwise, in the population surveyed in 1988, the average size was 17.00 mm, the standard deviation 4.67 mm and the proportion of infected children amounted to 4.14% against 4.48% in the control group. It is concluded that the method permits the estimation of the prevalence of tuberculosis infection among BCG-vaccinated school-children, provided that the vaccine has been given during the first year of life.

Validation of commercial DNA tests for quantitative beef quality traits.

Associations between 3 commercially available genetic marker panels (GeneSTAR Quality Grade, GeneSTAR Tenderness, and Igenity Tender-GENE) and quantitative beef traits were validated by the US National Beef Cattle Evaluation Consortium. Validation was interpreted to be the independent confirmation of the associations between genetic tests and phenotypes, as claimed by the commercial genotyping companies. Validation of the quality grade test (GeneSTAR Quality Grade) was carried out on 400 Charolais x Angus crossbred cattle, and validation of the tenderness tests (GeneSTAR Tenderness and Igenity Tender-GENE) was carried out on over 1,000 Bos taurus and Bos indicus cattle. The GeneSTAR Quality Grade marker panel is composed of 2 markers (TG5, a SNP upstream from the start of the first exon of thyroglobulin, and QG2, an anonymous SNP) and is being marketed as a test associated with marbling and quality grade. In this validation study, the genotype results from this test were not associated with marbling score; however, the association of substituting favorable alleles of the marker panel with increased quality grade (percentage of cattle grading Choice or Prime) approached significance (P < or = 0.06), mainly due to the effect of 1 of the 2 markers. The GeneSTAR Tenderness and Igenity TenderGENE marker panels are being marketed as tests associated with meat tenderness, as assessed by Warner-Bratzler shear force. These marker panels share 2 common mu-calpain SNP, but each has a different calpastatin SNP. In both panels, there were highly significant (P < 0.001) associations of the calpastatin marker and the mu-calpain haplotype with tenderness. The genotypic effects of the 2 tenderness panels were similar to each other, with a 1 kg difference in Warner-Bratzler shear force being observed between the most and least tender genotypes. Unbiased and independent validation studies are important to help build confidence in marker technology and also as a potential source of data required to enable the integration of marker data into genetic evaluations. As DNA tests associated with more beef production traits enter the marketplace, it will become increasingly important, and likely more difficult, to find independent populations with suitable phenotypes for validation studies.

Human papillomavirus infection: an anonymous prevalence study in South Wales, UK.

The objective of this study was to describe human papillomavirus (HPV) prevalence in South Wales in relation to age, cytology and social deprivation. This was an unlinked, prospective, anonymous, population-based study. DNA was purified from 1911 liquid-based cytology samples (mean age 37.7 years, cytology 93.2% negative, social deprivation average score 17.9) using quality assured techniques and the presence of virus determined by PCR-Enzyme Immuno Assay (PCR-EIA). 209 (10.9%) samples contained high-risk (HR) HPV infection of which 36.4% had multiple HR-HPV types. The most frequent HR types were HPV 16 (19.6%), HPV 35 (9.5%), HPV 66 (9.2%), HPV 59 (8.5%) and HPV 56 (7.6%). There was a strong association between HPV infection and cytological abnormality. Significantly more HR-HPV infections were detected in women under the age of 30 years (68.9% of all HR-HPV infections Fisher's exact test P=0.0001) compared to 30 years and above. There was no difference in HPV prevalence between different socioeconomic groups. The data presented suggest a different HPV type distribution in South Wales in comparison to that reported for other populations.
