Early discharge revisited: problems encountered with the home visit follow-up after the liberalization of eligibility criteria.

OBJECTIVE: To determine how changes in eligibility criteria for early discharge affected quality and costs of home nursing follow-up care for Medicaid patients. METHODS: A nurse screened women delivering vaginally to determine eligibility for discharge at 24-47 h. Maternal criteria were a vaginal delivery, no serious medical problems, > or = 8 h after bilateral tubal ligation and, if 24 h postpartum, by 21.00 on day of discharge. Newborn criteria were 36 weeks' gestation or more, 2000 g or greater and a normal examination at 24 h of age. By 48 h after discharge, a nursing visit was ordered for each mother and newborn. Nursing consultations were tracked and later entered into a database linked to hospital financial data. RESULTS: Of 3133 vaginal deliveries occurring from 1 August 1997 to 31 January 1999, eligibility criteria allowed 1799 mothers (58%) and 1587 newborns (51%) to be discharged early. Medical problems were rarely detected at follow-up (1% mothers, 2% newborns). To perform the increased number of visits, more personnel were hired and home nursing costs rose 150%. Despite the increased staff and costs, 19 mothers (1%) and ten newborns (0.6%) were lost to follow-up and 25 mothers (1%) and 20 newborns (1%) were visited beyond 72 h after discharge. CONCLUSIONS: Liberal changes in maternal and newborn eligibility criteria did not adversely affect the quality of home nursing follow-up care following early discharge. For hospitals performing a large number of early discharges, follow-up care using only a home nursing visit may be too expensive and difficult to organize. Alternative follow-up plans, such as clinic visits or phone calls, may also need to be utilized.

The importance of preparing medical students to manage different types of uncertainty.

Price competition and other aspects of the changing health care environment are threatening many academic health centers (AHCs) and causing them to reassess their education and research missions. In order to design effective AHCs for the next century, medical leaders must define the unique competencies needed by tomorrow's physicians and describe the educational enterprises required to produce physicians with these competencies. Two of the most important of these competencies are the ability to manage the uncertainty associated with creating clinical paradigms and the ability to manage the uncertainty associated with managing care delivery. Creating clinical paradigms involves (1) developing knowledge about disease categories and (2) developing knowledge about the most appropriate therapy for a disease in a particular category. Both these tasks involve uncertainty. The second type of uncertainty is associated with managing care delivery and is largely a matter of optimizing current clinical paradigms. The challenges are (1) to correctly assign patients' diseases to existing disease categories, and (2) to correctly choose and manage the delivery of the most appropriate therapies to these patients. Currently, AHCs are more competent in managing--and educating students to manage--the uncertainty involved in creating clinical paradigms. But there is an increasing demand for physicians who manage the second type of uncertainty associated with care delivery. The authors conclude that in order to remain viable, AHCs, and particularly their medical schools, must broaden their educational goals so that students can learn to manage both forms of uncertainty.

Impact of patient history on residents' evaluation on child sexual abuse.

OBJECTIVE: To determine if historical information influences residents' interpretation of physical findings in sexually abused children. METHODOLOGY: In a pediatric residency training program, all residents viewed 15 slides of children's genitalia (8 normal, 7 abnormal) with either a history specific for sexual abuse or one which was nonspecific. Three weeks later the same slides were viewed but with the alternate history scenario. The residents were asked if the physical findings were specific for sexual abuse. RESULTS: Sixty-four percent of residents completed both surveys. Correct response rate did not vary by gender or year of training. Responses were most often correct when the slide and history were normal (87%). Responses were least accurate when normal historical information was presented with abnormal slides (49%). A logistic regression model demonstrated that residents were less accurate when history and physical did not agree (95% CI = .54- .78). Reexamination of the data using areas under the Receiver Operating Characteristic (ROC) curve confirmed that residents performed on a less accurate ROC curve when the slide and history were incongruent (p < .01). CONCLUSION: Incongruency between patient history and physical exam findings negatively affected this group of residents' ability to discriminate between abuse and nonabuse findings.

Quality in the interorganizational setting.

For many patients, important health services are delivered by a process of care that spans several service organizations. Issues influencing the quality of care delivered across organizations are infrequently discussed in the health care quality literature. In this paper, interorganizational quality problems that detract from the care received by children with spina bifida, lead poisoning, and children who have been sexually abused are identified. Using concepts from the organizational behavior literature, both structural and group process approaches to addressing these problems are discussed to enhance the care received by children. A broader conceptualization of care delivery is required if patients whose care spans institutions are to benefit from quality improvement efforts.

Stability of the relationships between anabolic steroid use and multiple substance use among adolescents.

BACKGROUND: In a previous study, we tested the hypothesis that because adolescent anabolic steroid users are concerned with increasing muscle size and strength they are different from other substance users and are unlikely to use other drugs. Alternatively, if the causal factors of anabolic steroid use are similar to those for use of other substances, then adolescent anabolic steroid users would be expected to report poly drug use. Study findings confirmed the second hypothesis. PURPOSE: To test the stability of the relationships between anabolic steroid use and poly drug use over a four month period among ninth grade students. METHODS: All ninth grade students (1422) enrolled in compulsory health science classes in a country school system who had previously completed a modified version of the Centers for Disease Control and Prevention's 1989 Health Risk Survey and the 1990 Youth Risk Behavior Survey in November 1990 were asked to repeat the survey in February 1991. RESULTS: A higher percentage of males (4.7 percent) than females (2.9 percent, P < or = 0.018) reported anabolic steroid use without a doctor's prescription. As was found in the initial study, frequency of anabolic steroid use was significantly (P < 0.001) associated with frequency of use in the last 30 days of cocaine, injectable drugs, alcohol, marijuana, cigarettes, and smokeless tobacco. When those variables were analyzed with multiple regression analysis, the same four variables continued to be the best predictors of the frequency of anabolic steroid use, although the order that the variables entered into the multiple regression model changed. Use of smokeless tobacco, shared needles, cocaine, and marijuana explained more variation in the frequency of anabolic steroid use in the replication study (48.5%) than initially (32.8%). CONCLUSIONS: These findings support the hypothesis that adolescent anabolic steroid users are also likely to use other drugs and are engaging in shared needle use. These relationships remained relatively stable over a four month period of time.

An experimental evaluation of an AIDS educational intervention for WIC mothers.

The purpose of this study is to determine which of two educational approaches have the greater effect on the AIDS/human immunodeficiency virus (HIV) knowledge and attitudes of women participating in the Women, Infants, and Children (WIC) Program. A modified version of the Centers for Disease Control's (CDC) 1989 Health Risk Survey was administered to 217 women, who were then randomly assigned to either a control group receiving the usual written material, a nurse-educated group, or a videotape-educated group. The questionnaires were repeated immediately after and 2 months after the intervention. Chi square, Kruskall-Wallis ANOVA, and a repeated measures ANOVA were used for data analysis. Ninety-five percent of the subjects were black and the mean age was 25.8 years (+/- 5.9). The control group had significantly lower (p < or = 0.003) AIDS knowledge scores at both posttests, with the lowest knowledge level at 2 months. The videotape group had a greater (p < or = 0.048) intent to reduce risky behaviors at the initial posttest. Tolerance towards AIDS patients was significantly (p < or = 0.025) greater in the videotape and nurse groups. Both videotape and nurse education programs increased knowledge and influenced attitudes and behavioral intent. The more efficient videotape program had similar effects as the nurse program, and may be more generalizable to other populations.

Use of multiple drugs among adolescents who use anabolic steroids.

BACKGROUND: Because adolescent users of anabolic steroids are concerned with increasing muscle size and strength, they may be unique among substance users and unlikely to use other drugs. Alternatively, if the factors that cause the use of anabolic steroids are similar to those associated with the use of other substances, adolescents who use anabolic steroids would be expected to report use of other drugs as well. METHODS: We administered a questionnaire based on the 1989 Secondary School Health Risk Survey and the 1990 Youth Risk Behavior Survey of the Centers for Disease Control and Prevention to 1881 students enrolled in compulsory health-science classes (mean [+/- SD] age, 14.9 +/- 1.0 years) in the Richmond County, Georgia, school system. RESULTS: A higher percentage of boys (6.5 percent) than girls (1.9 percent, P < or = 0.001) reported using anabolic steroids without a doctor's prescription. Among ninth-grade students only, 5.4 percent of boys and 1.5 percent of girls reported using anabolic steroids (P < or = 0.001). Among users of anabolic steroids, 25 percent reported sharing needles to inject drugs. The frequency of anabolic-steroid use was significantly (P < 0.001) associated with the frequency of use in the previous 30 days of cocaine (r = 0.44), injectable drugs, alcohol (r = 0.23), marijuana (r = 0.42), cigarettes (r = 0.25), and smokeless tobacco (r = 0.40). On the basis of multiple regression analysis, the use of marijuana, shared needles, smokeless tobacco, and cocaine accounted for 33 percent of the variation in anabolic-steroid use among the ninth-grade students. CONCLUSIONS: In our study, adolescent users of anabolic steroids were likely to use other drugs as well, and many were sharing needles.

An evaluation of a school-based AIDS/HIV education program for young adolescents.

This study evaluated the efficacy of a school-based AIDS/human immunodeficiency virus (HIV) education program on 6th and 7th grade students. Using a quasi-experimental pretest-posttest control group design, a control group and an education group (intervention I) received both pretest and posttest questionnaires and a second education group (intervention II) was posttested only. Students were evaluated using a modified version of the Centers for Disease Control's Health Risk Survey. Students who received AIDS education were less likely (p < or = 0.0001) than the control group to report that they had changed their behavior to avoid getting AIDS, but thought they had a greater (p < or = 0.0002) chance of acquiring AIDS as an adult. In the intervention I group, males who had never received prior AIDS instruction were more worried about acquiring AIDS as an adult (p < or = 0.013). In the intervention II group, the education had a significant impact on the level of knowledge about AIDS/HIV infection (p < or = 0.0003) and the degree of tolerance toward students with AIDS (p < or = 0.0008), but the effect was not greater than the learning that occurred in the other 2 groups from testing alone. Students who were pretested were also less worried that they had been exposed to AIDS (p < or = 0.0001), more worried that they would die if they acquired AIDS (p < or = 0.05), and less likely to think AIDS patients should be isolated (p < or = 0.0005). Although this AIDS education program appeared to be moderately successful in this group of younger adolescents, significant learning also occurred fro testing alone.

AIDS/HIV knowledge level and perceived chance of having HIV among rural adolescents.

Behaviors that increase the risk of acquired immunodeficiency syndrome (AIDS) and human immunodeficiency virus (HIV) among adolescents living in rural areas have been reported to be as frequent as those of lower socioeconomic minority youth living in large urban areas. Little is known, however, about whether rural adolescents possess adequate knowledge upon which to make responsible decisions to avoid exposure to HIV. In order to address this deficit, we administered the Centers for Disease Control (CDC) 1989 Secondary School Health Risk Survey to 294 sixth, seventh, and eighth grade students (30.2% sample) from a rural county with significant social problems including epidemic sexually transmitted diseases STDs, sex-for-drugs, poverty, and drug abuse. The sample was 65% African-American, 50% female, with a mean age of 12.9 +/- 1.3 years. Although 68% reported having received school-based AIDS education, a lower proportion (greater than or equal to 10%) the students were found to correctly answer 8 of 17 AIDS/HIV knowledge questions than those from a national comparison group. The mean was 12.8 +/- 3.1 of 17 items answered correct. Lower AIDS/HIV knowledge was associated with lower school grade (rho = 0.46, p less than or equal to 0.0001); being African-American, Hispanic, or Native American (p less than or equal to 0.043); and never receiving school-based AIDS/HIV education (p less than or equal to 0.0001). Based on multivariate analysis of variance (ANOVA), only school-based AIDS/HIV education was a significant predictor (p less than or equal to 0.0001) of knowledge.(ABSTRACT TRUNCATED AT 250 WORDS)

An evaluation of a school-based AIDS/HIV education program for high school students.

The effect of a 1-hr school-based AIDS/HIV education program on the knowledge and attitudes of high school students was evaluated with a modified version of the Centers for Disease Control Health Risk Survey. One urban and one suburban school each were randomly assigned to an educational intervention (n = 535) or a control group (n = 659). All students received a posttest 2 weeks after the intervention. Knowledge was based on responses to 12 true-false questions (pretest alpha = .76, posttest alpha = 0.81). Principal components analysis was used to develop three attitude scales and risk-taking behavior was assessed by self-report. Data were analyzed with Kruskall-Wallis analysis of variance (ANOVA) and multivariate ANOVA. The groups did not differ in knowledge level at pretest. At posttest the education group had significantly (p < or = 0.006) higher knowledge even after controlling for the effects of previous AIDS education (p < or = 0.019), gender (p < or = 0.007), and Hispanic ethnicity (p < or = 0.048). After the education program, students were less worried about exposure to the AIDS virus, but were more worried (p < or = 0.048) about AIDS acquisition during their adult life. Although single school-based AIDS/HIV education programs may increase knowledge, more extensive education may be needed to change the behavior and attitudes of older high school students.

High school students' knowledge of HIV/AIDS and perceived risk of currently having AIDS.

Factors associated with AIDS knowledge and perceived risk of currently having HIV infection among adolescents were examined. A modified version of the Centers for Disease Control's Health Risk Survey was administered to 11th and 12th grade students (N = 2,483) in homerooms from nine schools in one southeastern community. Knowledge was based on cumulative responses to 12 questions. Many adolescents incorrectly answered seven questions. Based on multivariate analysis of variance, lower AIDS knowledge was associated with no prior school-based AIDS education (p less than or equal to 0.0001), previous IV drug use (p less than or equal to 0.0001), male gender (p less than or equal to 0.0001), and being Black or "other" ethnic group (p less than or equal to 0.0001). Based on interaction effects, Hispanics not receiving AIDS education in school (p less than or equal to 0.0001) and Black and "other" ethnic group IV drug users (p less than or equal to 0.0011) had a lower AIDS knowledge. When controlling for AIDS knowledge level (p less than or equal to 0.0001), higher perceived risk of current infection with HIV was associated with previous IV drug use (p less than or equal to 0.0001) and male gender (p less than or equal to 0.0001). However, previous IV drug users who never received AIDS education (p less than or equal to 0.0001) or were from Black or "other" ethnic group (p less than or equal to 0.008) had higher perceived risks of presently having HIV infection.

Correlates of children's bicycle helmet use and short-term failure of school-level interventions.

To test the utility of school-level interventions for child bicycle safety and to identify social and behavioral factors associated with children's bicycle helmet use, a two-level intervention was conducted in two suburban elementary schools. Children (N = 209) and parents (N = 125) in school 1 and in school 2 (children, N = 470; parents, N = 364) were surveyed regarding bicycle injuries and helmet use. Children and parents in schools 1 and 2 received literature about bicycle safety and discount coupons for helmet purchase. School 1 was then the target of an intensive safety campaign, including meetings with the school safety committee and the PTA and a classroom presentation to children emphasizing helmet use. Ten months later the same survey was again administered. Children in school 1 were more likely at posttest to believe that helmets were protective (P = .003) but did not differ on other variables. Logistic regression showed that sibling helmet ownership, parental helmet use, and lower parental perceived social barriers to helmet use were independently associated with children's reported helmet use and with parental intent for the child to use a helmet at posttest.
