Correlates of HIV antiretroviral adherence in persons with serious mental illness.

Although several studies have examined the relationship between symptoms of depression or psychological distress and medication adherence, this is the first published study of HIV antiretroviral adherence and its correlates among persons diagnosed with serious mental illness. Forty-five of 47 (96%) participants completed a two-week study in which their adherence to antiretroviral medication was measured using electronic monitoring caps. Mean adherence (proportion of prescribed doses taken) was 66% (SD=34). There were several correlates (p<0.05) of adherence among background and medical characteristics, physical symptoms and side effects, cognitive and psychosocial functioning, and treatment-related attitudes and beliefs. However, in a forward stepwise regression, attendance at recent clinical appointments was the sole predictor that entered the model--accounting for 49% of the variance in adherence. Using attendance at recent clinic appointments as the criterion, adherence readiness (90+% adherence to antiretrovirals) was correctly determined for 72% of the sample. Although not sufficient to serve as the basis for treatment decision making, review of appointment-keeping records may provide clinicians with a simple, cost-effective method for predicting adherence to ongoing treatment, as well as for evaluating adherence readiness to inform the decision of whether to prescribe or defer treatment.

Changes in health-promoting behavior following diagnosis with HIV: prevalence and correlates in a national probability sample.

Diet, exercise, smoking, and substance use patterns affect the course of illness and quality of life for people with HIV. In interviews with a national probability sample of 2,864 persons receiving HIV care, it was found that most had made health-promoting changes in one or more of these behaviors since diagnosis. Many reported increased physical activity (43%) and improved diet (59%). Forty-nine percent of cigarette smokers quit or cut down; 80% of substance users did so. Desire for involvement in one's HIV care and information seeking-positive coping were the most consistent correlates of change. Other correlates varied by health practice but included health status, emotional well-being, demographics, and attitudes toward other aspects of HIV care. Most people with HIV improve their health behavior following diagnosis, but more might be helped to do so by targeting these behaviors in future interventions.

Fertility desires and intentions of HIV-positive men and women.

CONTEXT: HIV-positive men and women may have fertility desires and may intend to have children. The extent of these desires and intentions and how they may vary by individuals' social and demographic characteristics and health factors is not well understood. METHODS: Interviews were conducted from September through December 1998 with 1,421 HIV-infected adults who were part of the HIV Cost and Services Utilization Study, a nationally representative probability sample of 2,864 HIV-infected adults who were receiving medical care within the contiguous United States in early 1996. RESULTS: Overall, 28-29% of HIV-infected men and women receiving medical care in the United States desire children in the future. Among those desiring children, 69% of women and 59% of men actually expect to have one or more children in the future. The proportion of HIV-infected women desiring a child in the future is somewhat lower than the overall proportion of U.S. women who desire a child. The fertility desires of HIV-infected individuals do not always agree with those of their partners: As many as 20% of HIV-positive men who desire children have a partner who does not Generally, HIV-positive individuals who desire children are younger, have fewer children and report higher ratings of their physical functioning or overall health than their counterparts who do not desire children, yet desire for future childbearing is not related to measures of HIV progression. HIV-positive individuals who expect children are generally younger and less likely to be married than those who do not. Multivariate analyses indicate that black HIlV-positive individuals are more likely to expect children in the future than are others. While HIV-positive women who already have children are significantly less likely than others both to desire and to expect more births, partner's HIV status has mixed effects: Women whose partner's HIVstatus is known are significantly less likely to desire children but are significantly more likely to expect children in the future than are women whose partner's HIV status is unknown. Moreover, personal health status significantly affects women's desire for children in the future but not men's, while health status more strongly influences men's expectations to have children. CONCLUSIONS: The fact that many HIV-infected adults desire and expect to have children has important implications for the prevention of vertical and heterosexual transmission of HIV, the need for counseling to facilitate informed decision-making about childbearing and childrearing, and the future demand for social services for children born to infected parents.

Assessing symptoms before hysterectomy: is the medical record accurate?

OBJECTIVE: Our purpose was to evaluate the agreement between the documentation of symptoms leading to hysterectomy and the assessment of those symptoms by the patient. STUDY DESIGN: A retrospective study was performed of 497 women in southern California who had hysterectomies. Sensitivity, specificity, and kappa statistics were calculated for the medical records and were compared with patient interviews for the presence and severity of symptoms. RESULTS: The medical record was 93% sensitive and 61% specific for identifying bleeding and 79% sensitive and 55% specific for identifying pain. Overall agreement between physician records and patient interviews was moderate for bleeding (kappa, 0.55-0.58), fair for pain (kappa, 0.29-0.34), and poor for impairment as a result of bleeding or pain (kappa, 0.0-0.14). CONCLUSIONS: Physician overestimation of symptoms could lead to overuse of hysterectomy, whereas underestimation could result in underuse. Our results suggest that both underestimation and overestimation occur for patients with abnormal bleeding, pain, or both. If physicians accurately assess symptoms but fail to document them, examinations of appropriateness will be faulty unless patients are interviewed.

End-of-life discussions and preferences among persons with HIV.

CONTEXT: Deficits in advance care planning leave many patients and their physicians unprepared for decisions about end-of-life care. Even though the prognosis has improved for many persons with human immunodeficiency virus (HIV) infection, a need for planning remains. OBJECTIVE: To evaluate prevalence of end-of-life discussions, use of advance directives, and preferences concerning end-of-life care and their relationship with patient demographics, clinical status, psychosocial variables, and practitioner characteristics among HIV-infected persons. DESIGN, SETTING, AND PATIENTS: Cross-sectional survey of a US probability sample of 2864, which represents 231 400 adults receiving care for HIV, conducted from January 1996 to April 1997. MAIN OUTCOME MEASURES: Communication with physician regarding end-of-life issues, completion of an advance directive, preference for aggressiveness of care, and willingness to tolerate future permanent adverse health states. RESULTS: A total of 1432 patients (50%) discussed some aspect of end-of-life care with their practitioner and 1088 (38%) completed an advance directive. Patients were more likely to complete an advance directive after a physician discussion (odds ratio [OR], 5.82; 95% confidence interval [CI], 4.50-7.52). Practitioners discussed end-of-life care less with blacks (OR, 0.57; 95% CI, 0.39-0.83) and Latinos (OR, 0.74; 95% CI, 0.55-0.98) than with whites. Women (OR, 1.39; 95% CI, 1.05-1.84) and patients with children in the household (OR, 1.53; 95% CI, 1.12-2.10) communicated the most with practitioners about end-of-life issues. Patients infected with HIV via injection drug use (OR, 0.64; 95% CI, 0.45-0.89) and those with less education communicated the least with physicians about end-of-life issues. Less denial, greater trust in one's practitioner, and longer patient-practitioner relationship were associated with more advance care planning. CONCLUSIONS: Half of all persons infected with HIV are at risk of making end-of-life decisions without prior discussions with their health care practitioners. Blacks, Latinos, intravenous drug users, and less educated individuals need advance care planning interventions in clinical HIV programs.

Health information on the Internet: accessibility, quality, and readability in English and Spanish.

CONTEXT: Despite the substantial amount of health-related information available on the Internet, little is known about the accessibility, quality, and reading grade level of that health information. OBJECTIVE: To evaluate health information on breast cancer, depression, obesity, and childhood asthma available through English- and Spanish-language search engines and Web sites. DESIGN AND SETTING: Three unique studies were performed from July 2000 through December 2000. Accessibility of 14 search engines was assessed using a structured search experiment. Quality of 25 health Web sites and content provided by 1 search engine was evaluated by 34 physicians using structured implicit review (interrater reliability >0.90). The reading grade level of text selected for structured implicit review was established using the Fry Readability Graph method. MAIN OUTCOME MEASURES: For the accessibility study, proportion of links leading to relevant content; for quality, coverage and accuracy of key clinical elements; and grade level reading formulas. RESULTS: Less than one quarter of the search engine's first pages of links led to relevant content (20% of English and 12% of Spanish). On average, 45% of the clinical elements on English- and 22% on Spanish-language Web sites were more than minimally covered and completely accurate and 24% of the clinical elements on English- and 53% on Spanish-language Web sites were not covered at all. All English and 86% of Spanish Web sites required high school level or greater reading ability. CONCLUSION: Accessing health information using search engines and simple search terms is not efficient. Coverage of key information on English- and Spanish-language Web sites is poor and inconsistent, although the accuracy of the information provided is generally good. High reading levels are required to comprehend Web-based health information.

A national survey of stress reactions after the September 11, 2001, terrorist attacks.

BACKGROUND: People who are not present at a traumatic event may also experience stress reactions. We assessed the immediate mental health effects of the terrorist attacks on September 11, 2001. METHODS: Using random-digit dialing three to five days after September 11, we interviewed a nationally representative sample of 569 U.S. adults about their reactions to the terrorist attacks and their perceptions of their children's reactions. RESULTS: Forty-four percent of the adults reported one or more substantial stress symptoms; 91 percent had one or more symptoms to at least some degree. Respondents throughout the country reported stress syndromes. They coped by talking with others (98 percent), turning to religion (90 percent), participating in group activities (60 percent), and making donations (36 percent). Eighty-five percent of parents reported that they or other adults in the household had talked to their children about the attacks for an hour or more; 34 percent restricted their children's television viewing. Thirty-five percent of children had one or more stress symptoms, and 47 percent were worried about their own safety or the safety of loved ones. CONCLUSIONS: After the September 11 terrorist attacks, Americans across the country, including children, had substantial symptoms of stress. Even clinicians who practice in regions that are far from the recent attacks should be prepared to assist people with trauma-related symptoms of stress.

Promoting adolescent health: worksite-based interventions with parents of adolescents.

A promising public health approach for reducing adolescent risk behavior is to recognize and support the role of parents in promoting healthful behaviors. Although there are various settings where parents can be reached, this article focuses on one particular setting--the parent's place of employment. The article discusses the development and implementation of parenting programs for parents of adolescents. Such programs are new and should be evaluated to determine whether they are effective.

Do consumer reports of health plan quality affect health plan selection?

OBJECTIVE: To learn whether consumer reports of health plan quality can affect health plan selection. DATA SOURCES: A sample of 311 privately insured adults from Los Angeles County. STUDY DESIGN: The design was a fractional factorial experiment. Consumers reviewed materials on four hypothetical health plans and selected one. The health plans varied as to cost, coverage, type of plan, ability to keep one's doctor, and quality, as measured by the Consumer Assessment of Health Plans Study (CAHPS) survey. DATA ANALYSIS: We used multinomial logistic regression to model each consumer's choice among health plans. PRINCIPAL FINDINGS: In the absence of CAHPS information, 86 percent of consumers preferred plans that covered more services, even though they cost more. When CAHPS information was provided, consumers shifted to less expensive plans covering fewer services if CAHPS ratings identified those plans as higher quality (59 percent of consumers preferred plans covering more services). Consumer choices were unaffected when CAHPS ratings identified the more expensive plans covering more services as higher quality (89 percent of consumers preferred plans covering more services). CONCLUSIONS: This study establishes that, under certain realistic conditions, CAHPS ratings could affect consumer selection of health plans and ultimately contain costs. Other studies are needed to learn how to enhance exposure and use of CAHPS information in the real world as well as to identify other conditions in which CAHPS ratings could make a difference.

Propensity of HIV patients to seek urgent and emergent care. HIV Cost and Services Utilization Study Consortium.

OBJECTIVE: To assess the propensity of HIV-infected adults to seek care for common symptoms, and to determine whether they would seek care in the emergency department (ED) or with their primary care provider. DESIGN: Cross-sectional interview study. SETTING: Patients in care in the 48 contiguous United States. PARTICIPANTS: A nationally representative group of HIV- infected adults selected using multistage probability sampling. MEASUREMENTS: Subjects were interviewed between January 1996 and April 1997. Patients with advanced disease (past AIDS diagnosis and/or CD4 cell count <200/microL) and early disease were asked how they would seek care for key HIV-associated symptom complexes. Three advanced disease and 3 early disease symptom scenarios were used. MAIN RESULTS: Most advanced disease patients (78% to 87%) would seek care right away from the ED or primary care provider for the symptoms asked. Most early disease patients (82%) would seek care right away for new respiratory symptoms; fewer would do so for headache (46%) or oral white patches (62%). In a multivariate model, independent predictors of propensity to use the ED for advanced disease symptoms included African-American ethnicity (adjusted odds ratio [OR], 2.5; 95% confidence interval [95% CI], 1.8 to 3.4); less education (adjusted OR, 1.4; 95% CI, 1.1 to 1.7); drug dependence (adjusted OR, 1.4; 95% CI, 1.1 to 1.7); annual income less than $5,000 (adjusted OR, 1.5; 95% CI, 1.0 to 2.3); and lower psychological well-being (adjusted OR, 0.9; 95% CI, 0.9 to 1.0). In early disease, the following independently predicted ED use: African American (adjusted OR, 4.7; 95% CI, 3.1 to 7.1) or Hispanic ethnicity (adjusted OR 2.4; 95% CI, 1.4 to 4.3), female gender (adjusted OR, 1.6; 95% CI, 1.2 to 2.2), annual income less than $5,000 (adjusted OR, 1.8; 95% CI, 1.1 to 3. 0), and lower psychological well-being (adjusted OR, 0.9; 95% CI, 0. 8 to 1.0). CONCLUSIONS: Many patients would use the ED instead of same-day primary care for several common symptoms of HIV disease. African Americans, the poor, and patients with psychological symptoms had a higher propensity to use the ED.

HIV-infected parents and their children in the United States.

OBJECTIVES: This study sought to determine the number, characteristics, and living situations of children of HIV-infected adults. METHODS: Interviews were conducted in 1996 and early 1997 with a nationally representative probability sample of 2864 adults receiving health care for HIV within the contiguous United States. RESULTS: Twenty-eight percent of infected adults in care had children. Women were more likely than men to have children (60% vs 18%) and to live with them (76% vs 34%). Twenty-one percent of parents had been hospitalized during the previous 6 months, and 10% had probably been drug dependent in the previous year. Parents continued to have children after being diagnosed with HIV: 12% of all women conceived and bore their youngest child after diagnosis, and another 10% conceived before but gave birth after diagnosis. CONCLUSIONS: Clinical and support services for people affected by the HIV epidemic should have a family focus.

The appropriateness of recommendations for hysterectomy.

OBJECTIVE: To evaluate the appropriateness of recommendations for hysterectomies done for nonemergency and non-oncologic indications. METHODS: We assessed the appropriateness of recommendations for hysterectomy for 497 women who had the operation between August 1993 and July 1995 in one of nine capitated medical groups in Southern California. Appropriateness was assessed using two sets of criteria, the first developed by a multispecialty expert physician panel using the RAND/University of California-Los Angeles appropriateness method, and the second consisting of the ACOG criteria sets for hysterectomies. The main outcome measure was the appropriateness of recommendation for hysterectomy, based on expert panel ratings and ACOG criteria sets. RESULTS: The most common indications for hysterectomy were leiomyomata (60% of hysterectomies), pelvic relaxation (11%), pain (9%), and bleeding (8%). Three hundred sixty-seven (70%) of the hysterectomies did not meet the level of care recommended by the expert panel and were judged to be recommended inappropriately. ACOG criteria sets were applicable to 71 women, and 54 (76%) did not meet ACOG criteria for hysterectomy. The most common reasons recommendations for hysterectomies considered inappropriate were lack of adequate diagnostic evaluation and failure to try alternative treatments before hysterectomy. CONCLUSION: Hysterectomy is often recommended for indications judged inappropriate. Patients and physicians should work together to ensure that proper diagnostic evaluation has been done and appropriate treatments considered before hysterectomy is recommended.

Quality of life among women undergoing hysterectomies.

OBJECTIVE: To measure the association between gynecologic conditions and quality of life in women before hysterectomy. METHODS: We retrospectively identified 482 women who had hysterectomies for nononcologic and nonemergency indications in one of nine capitated medical groups in Southern California between 1993 and 1995. Their symptoms and quality of life before hysterectomy were assessed by medical record review and telephone interview. Women were placed into four symptom-based groups (pain, bleeding, pelvic discomfort, and asymptomatic groups) and compared across six quality-of-life scales. RESULTS: Women with primary pain conditions reported the highest average role impairment compared with women with primary bleeding, pelvic discomfort, or asymptomatic conditions (8.6 days/month versus 5.0, 2.5, and 1.9 days/month, respectively; P < .05). On the five 0 to 100-point quality-of-life scales, women with primary pain conditions, compared with women with bleeding, pelvic discomfort, or asymptomatic conditions, had the highest mean levels of sexual impairment (71.5 versus 54.1, 29.6, and 17.9, respectively; P < .05) and mood impairment (55.2 versus 45.2, 34.6, and 38.1, respectively; P < .05), the poorest perception of general health (74.4 versus 60.7, 44.1, and 49.4, respectively; P < .05), and the greatest increase in severity of symptoms before hysterectomy (77.2 versus 68.7, 61.5, and 57.1, respectively; P < .05). CONCLUSION: Women's primary symptoms before hysterectomy are associated differentially with varying levels of impairment. Standardized measurement of quality of life among women with gynecologic complaints that lead to hysterectomy might help in the development of treatment guidelines and in the assessment of appropriateness and outcomes of care for those women.

HIV and people with serious mental illness: the public sector's role in reducing HIV risk and improving care.

OBJECTIVE: The paper discusses issues related to the detection, prevention of transmission, and treatment of human immunodeficiency virus (HIV) infection among persons with serious mental illness and suggests ways public mental health systems can address these issues. METHODS: MEDLINE was searched from 1980 through 1998, and all pertinent references were reviewed. RESULTS: Persons with severe mental illness are at greatly increased risk of HIV infection due to increased likelihood of high-risk sexual behaviors and injection drug use. The formidable barriers to detection and effective treatment of HIV that exist in this population can be attributed to the unique characteristics of this population, lack of knowledge and expertise among mental and physical health care providers, and fragmented mental and physical health care systems. CONCLUSIONS: In the last five years, treatments for HIV that are far more efficacious than earlier treatments have become available, making it more important for HIV infection be detected and treated among persons with serious mental illness. Public mental health systems need to implement active prevention policies and practices, educate both mental health and physical health care providers about key treatment issues, and develop effective linkages between mental and physical health care providers and systems.

Making survey results easy to report to consumers: how reporting needs guided survey design in CAHPS. Consumer Assessment of Health Plans Study.

OBJECTIVES: CAHPS is designed to report information about health care quality from the consumer perspective. Enrollees are surveyed about their experiences with their health plan and medical care, and results are reported to other consumers choosing among health plans. Based on survey instruments designed to elicit reliable and valid information about health plan experiences from plan enrollees, the aim of the CAHPS team was to design a series of reporting products that present survey results so that consumers find the information understandable, meaningful, and useful in choosing among health plans. METHODS: Design of the survey instruments and reporting products were closely linked. The approach to reporting was based on previous research on consumers' information interests and needs in evaluating and choosing among plans. Cognitive tests were conducted with consumers to get their reactions to mock-ups of various approaches to reporting CAHPS survey results. RESULTS: Findings from previous research and cognitive testing, together with feedback from various experts and the public, were used to modify the survey questions, response options, and reporting formats to make it easier for consumers to understand and use reports. Changes included dropping topics of less interest to consumers, changing question wordings that were hard to understand, minimizing the number of different response categories, and revising questions to make them easier to group together for purposes of reporting. CONCLUSIONS: The CAHPS focus on reporting results to consumers presented an unusual challenge for survey design, requiring close coordination between instrument design and report development to produce a survey and reporting kit that serves consumers' information needs.

The sexual practices of Asian and Pacific Islander high school students.

PURPOSE: To describe the sexual behaviors, beliefs, and attitudes of Asian and Pacific Islander California high school students and to compare them to other racial/ethnic groups. METHODS: Data were collected from an anonymous self-administered survey of 2026 ninth to 12th graders in a Los Angeles County school district; 186 of the respondents described themselves as Asian and Pacific Islander. The survey was conducted in April 1992. RESULTS: A higher percentage of Asian and Pacific Islander adolescents (73%) compared with African-American (28%, p < .001), Latino (43%, p < .001), white (50%, p < .001), and other (48%, p < .001) adolescents had never had vaginal intercourse. Asian and Pacific Islander adolescents were less likely than other adolescents to report having engaged in heterosexual genital sexual activities during the prior year, including masturbation of or by a partner, fellatio with ejaculation, cunnilingus, and anal intercourse. Few students in any group reported homosexual genital sexual activities. Asians and Pacific Islanders who had had vaginal intercourse were more likely than most other groups to have used a condom at first vaginal intercourse, but Asians and Pacific Islanders had not used condoms more consistently over the prior year. Asians and Pacific Islanders were more likely to expect parental disapproval if they had vaginal intercourse and less likely to think that their peers had had vaginal intercourse. CONCLUSIONS: Asian and Pacific Islander high school students in one California school district appear to be at lower sexual risk than other racial/ethnic groups. However, a large minority are engaging in activities that can transmit disease and lead to unwanted pregnancy. Therefore, current efforts to develop culturally sensitive clinical and community-based approaches to sexual risk prevention should include Asians and Pacific Islanders.

PIP: Findings are reported from a study conducted to describe the sexual behaviors, beliefs, and attitudes of Asian and Pacific Islander California high school students, and to compare them with other racial/ethnic groups. Data were collected from an anonymous self-administered survey in April 1992 of 2026 9th-12th graders in a Los Angeles County school district. 186 of the respondents described themselves as Asian and Pacific Islander. 73% of Asian and Pacific Islander students had never had vaginal sexual intercourse, compared to 28% of African-American students, 43% of Hispanics, 50% of Whites, and 48% of others. Asians and Pacific Islanders were less likely than other adolescents to report having engaged in heterosexual genital activities during the preceding year. Few students in any racial/ethnic group reported engaging in homosexual genital sexual activities. Asians and Pacific Islanders who had had vaginal intercourse were more likely than students in most other groups to have used a condom at first vaginal intercourse, but they had not used condoms more consistently during the previous year. Furthermore, Asians and Pacific Islanders were more likely to expect parental disapproval if they had vaginal intercourse and were less likely to think that their peers had had such intercourse.

Impact of a high school condom availability program on sexual attitudes and behaviors.

CONTEXT: While making condoms available in high schools has provoked much debate, evidence on the actual effects of such programs on students' attitudes and behavior is sparse. METHODS: Prior to implementation of a condom availability program in a Los Angeles County high school, 1,945 students in grades 9-12 (98% of eligible students) completed a self-administered anonymous survey on their sexual behavior and on related knowledge and attitudes; one year later, 1,110 students (59% of eligible students) completed a follow-up survey. RESULTS: There was no significant change over time in the percentage of males or females who had ever had vaginal intercourse or who had had vaginal intercourse during the year prior to the survey. The percentage of males who reported using condoms every time they engaged in vaginal intercourse during the past year increased significantly, from 37% to 50%, and the percentage of males who reported condom use at recently initiated first vaginal intercourse increased from 65% to 80%. On the other hand, female respondents showed no significant change in their condom use. The self-reported likelihood of using a condom for vaginal intercourse during the following year did not change significantly for students who had had vaginal intercourse, but it increased dramatically for those who, had never had vaginal intercourse. The students' attitudes toward sex and condom use either remained the same between surveys or changed in a direction favoring less sexual behavior and greater risk prevention. CONCLUSIONS: The condom availability program appears not to have produced an increase in sexual activity among high school students, and it appears to have led to improved condom use among males. The apparent strong effect on students' intention to use condoms and on males' use at first vaginal intercourse suggests that such programs may have a particular impact on the least sexually experienced adolescents.

PIP: By early 1995, at least 431 schools in 50 US school districts had established programs making condoms available to students in response to fears about HIV, other sexually transmitted diseases (STDs), and pregnancy among teenagers. Program opponents argue that such programs lead students to believe that schools condone their engagement in sexual activity, and are therefore encouraging them to have sex. Findings are presented from a pre/post-test evaluation of a school-based condom availability program in a Los Angeles County high school, based upon survey responses from 1945 students in grades 9-12. The 1945 students who provided survey data in April 1992 before the condom program began comprised 98% of eligible students. 1110 students, 59% of eligible students. completed a follow-up survey 1 year later after the program began. At baseline, 55.8% of the boys and 45.4% of girls had ever experienced vaginal intercourse. 1 year later, these percentages were 55.0% and 46.1%, respectively. There was also no significant change over time in the percentage of males or females who had had vaginal intercourse during the year before the survey. The percentage of males who reported using condoms every time they engaged in vaginal intercourse during the past year increased from 37% to 50%, while the percentage of males who reported condom use at recently initiated first vaginal intercourse increased from 65% to 80%. There was, however, no significant change among female respondents in their level of condom use. The self-reported likelihood of using a condom for vaginal intercourse during the following year did not change significantly for students who had had vaginal intercourse, but it did increase considerably for those who had never had vaginal intercourse. Respondents' attitudes toward sex and condom use either remained the same between surveys or changed in a direction favoring less sexual behavior and greater risk prevention.

Treatment adequacy for HIV-related pneumocystis pneumonia: quality measures for inpatient care.

To develop and evaluate severity-adjusted indicators of treatment timeliness and adequacy for inpatient care of first episode of HIV-related pneumocystis pneumonia, a retrospective cohort study (n = 414) using medical record review was conducted in six California medical centers (1 January 1983-30 June 1987). Measures included patient baseline characteristics and complexity, process-of-care indicators (delay in treatment initiation and proportion of adequate treatment delivered), and overall survival of hospitalization and survival without respiratory failure. Logistic regression models of severity were developed among optimally treated patients and cross-validated. Exposure to medication with pneumocystis activity within 30 days prior to admission was protective. After controlling for pre-admission medication and severity, the average proportion of adequate pneumocystis medication delivered during the first 7 and 30 days were significant predictors of outcome in all models. Delay in treatment initiation, while not a statistically significant predictor, was associated with baseline severity. Summary measures of treatment adequacy show promise as process-of-care indicators.
