Computed tomography in patients with abdominal pain and diarrhoea: does the benefit outweigh the drawbacks?

The role of computed tomography (CT) in the evaluation of abdominal pain is well established. However, concern exists in regard to procedure-related radiation levels, contrast-medium toxicity and costs. We sought to determine whether the use of abdominal CT caused major changes in the management of patients who had abdominal pain and diarrhoea. We reviewed all abdominal CT examinations that were performed at our hospital from October through December 2010. We selected 574 scans that had been performed in patients who presented with or without diarrhoea. We examined the selected medical records to determine whether the CT scan changed patients' management. A scan was considered to be management changing if a decisive intervention occurred on the basis of the scan results. Among 124 scans in patients with diarrhoea and 450 scans in patients without diarrhoea, the scan results changed management in 13 of the patients with diarrhoea (11%) and in 233 of those without diarrhoea (52%) (P < 0.001). When management changed, the changes resulted from findings unrelated to diarrhoea. Despite its defined role in the assessment of abdominal pain, CT of patients that also had diarrhoea seldom caused a major change in management. The probability of CT causing such a change does not outweigh the cost, radiation risk or potential for contrast-induced nephropathy.

Evidence of intraprison spread of HIV infection.

BACKGROUND: Individuals entering prison are known to have high rates of human immunodeficiency virus (HIV) infection, and inmates are known to engage in high-risk behavior. This suggests the potential for intraprison spread of HIV infection, but this has not been documented. METHODS: All prisoners (N = 556) in the Florida Department of Corrections who had been continuously incarcerated since 1977 were identified. The medical records of these prisoners were reviewed to determine whether they had been tested for HIV infection and, if tested, whether the results were positive. Results were considered positive if there were reactions to two enzyme-linked immunosorbent assays confirmed by Western blot assay. If an individual tested positive, the medical record was reviewed to determine whether the patient had been treated for conditions consistent with HIV infection. RESULTS: Eighty-seven of the 556 prisoners had undergone testing for HIV infection. Of the tested inmates, 18 (21%) were found to be positive for HIV infection. Eight of these individuals had no HIV-related conditions, and 10 had HIV-related symptoms. CONCLUSIONS: The results present strong evidence for intraprison transmission of HIV infection. Given that most inmates serve relatively short sentences, there is a strong possibility that prison-acquired HIV infection will be carried into the "free world." Preventive programs in prisons may be very important in controlling HIV infection in our society.

Tuberculosis control in health care workers: an algorithmic approach.

Health care workers have always been at risk for contracting tuberculosis (TB) from patients with active disease. In addition, health care workers who have active TB pose a risk for transmitting TB to patients. As a result, institutions that employ health care professionals must adopt programs to reduce the probability of transmission of TB to their employees or their patients. This article discusses the new guidelines for preventing TB issued by the Centers for Disease Control and Prevention and suggests approaches for adapting the guidelines to the needs of individual institutions. It emphasizes the importance of skin testing for early detection, correct interpretation of the tests, the approaches to determining who should be tested, and the relative frequency with which employees should be tested. It presents algorithms to assist employee health and infection control personnel in screening current and prospective employees, and in responding to positive and negative test results, and the booster effect.

An approach to an index of hospital performance.

Two indexes are described, based on measures of administrative effectiveness and patient care effectiveness. The measures used were selected and ranked by a Delphi panel from a list of 30 measures drawn from the literature. Weights were assigned by the panel to 19 selected measures. The resulting indexes did well in a test on data collected from 32 Texas hospitals.

Assessing the influence of non-treatment variables in a study of outcome from severe head injuries.

An evaluation was made of the impact of non-treatment variables on severely injured head trauma patients. The principal findings were: 1) severity of injury was the best predictor of outcome; 2) patient's age had a statistically significant but marginally useful impact on outcome; 3) a regression analysis showed that duration of transport, up to 4 hours, had no impact on outcome; 4) time from accident to intubation had a marginal impact on outcome; and 5) one-way analysis of variance showed that mode of transportation, whether helicopter, ambulance, or other means had no impact on outcome.

Oropharyngeal lesions in AIDS.

Any physician who is treating HIV-infected patients can expect to deal with individuals who are or will be experiencing the physical manifestations of the disease. Fortunately, most of these conditions can be successfully treated; other cases have palliative treatments that can improve quality of life and assist in pain reduction and suffering. All patients with HIV need to be managed jointly throughout their illnesses so that these patients do not receive conflicting advice, prescriptions, and so forth. Also, patients benefit from receiving care from the specialist that is most appropriate for their condition. The physician or dentist working alone can often help the patient; when they work together, however, optimum care is likely the result.

A collaborative program between a school of public health and a local health department to increase HIV testing of pregnant women.

OBJECTIVE: This study evaluates the effectiveness of a continuing medical education (CME) program that sought to increase HIV testing of women attending maternity clinics of the City of Houston Department of Health and Human Services (HDHHS). The CME program consisted of 14 training sessions given in 1995, 1996, 1997, 1999, and 2000. Educational objectives included increasing patient knowledge of HIV perinatal testing, increasing patient appreciation of the importance of HIV testing, and developing staff skills in educating and counseling women to accept HIV testing during pregnancy. METHODS: The CME program was based on assessment of clinician learning needs and an algorithm of the testing process, both jointly developed by faculty from the University of Texas Health Science Center at Houston School of Public Health and HDHHS personnel. The algorithm was also used to assess the care delivered. The CME was evaluated by examining changes in the percentage of women tested in the maternity clinics. RESULTS: In 1995, the year before the education program, 5.7% of women seen in the maternity clinics were tested for HIV. After the program began, testing rates rose to 64.2% in 1996, 65.5% in 1997, and 43.3% in 1998. Given the decline in testing in 1998, additional CME sessions were conducted in 1999-2000. The rate of testing rose to 62.3% in 1999 and 76.5% in 2000. CONCLUSION: Cooperative planning between university and health department personnel can create CME programs that alter provider behaviors and service delivery patterns to increase HIV testing. Outcomes need to be regularly monitored, however, to determine the need for maintenance or performance reinforcement.

Low-income minority women at risk for cervical cancer: a process to improve adherence to follow-up recommendations.

OBJECTIVE: The Houston Department of Health and Human Services (HDHHS) has a centralized process for notifying and setting up follow-up appointments for women with abnormal Pap smears who are clients of HDHHS health centers. Faculty and a student from the University of Texas School of Public Health and HDHHS personnel jointly conducted a study to evaluate the process and performance of the system. METHODS: The study examined two subpopulations: women with atypical squamous cells of undetermined significance or low-grade squamous intraepithelial lesions (ASCUS/LGSIL) and women with high-grade squamous intraepithelial lesions or atypical glandular cells of undetermined significance (HGSIL/AGCUS). A retrospective study was conducted of data on women attending eight HDHHS clinics during the period from February 1996 through August 2000. Records of 1,216 women referred for evaluation of abnormal Pap smears were reviewed. Process effectiveness was measured by the number of successful contacts made and the number of appointments set up. Performance was measured by compliance with referral appointments. Predictors included race/ethnicity, age, co-existence of a sexually transmitted disease, number of prior referrals, type of patient visit, and health center attended. RESULTS: HDHHS staff successfully notified 95.6% of women with ASCUS/LGSIL and 97.9% of women with HGSIL/AGCUS. Using performance criteria as outcome measures, high-risk women requiring targeted interventions were identified. Overall, 84.2% of women scheduled appointments. Among those with ASCUS/LGSIL, women identified as African American were 53% less likely to accept an appointment and 45% less likely to show up for the appointment than those identified as Hispanic or "other." Age and type of patient visit appeared to be significantly associated with patient compliance behavior. CONCLUSION: The study describes the effectiveness of a centralized patient follow-up process for women at risk for cervical cancer.

Psychological states in HIV disease and the nursing response.

The authors review the four major psychological states of HIV infection as described by Nichols (1985) and adapt these manifestations for use by the nurse in the clinical setting. The states and their likely impacts are described. The diagnostic tools for recognizing the states, assessment questions that help establish the patient's psychological state, and nursing interventions are included.

A preliminary study of African-American physician involvement in the care of HIV-infected patients.

In 1995, questionnaires were sent to the mailing list of the National Medical Association (NMA). The mail responses were supplemented by questionnaires distributed at the NMA annual meeting. Of the 709 respondents, approximately 63% were primary care providers, pediatricians, or obstetrician-gynecologists; 72% were treating from zero to 10 human immunodeficiency virus (HIV) patients while 9% were treating > 90 HIV patients; and 12% had been treating HIV patients > 10 years. The majority of these patients were African American; male-to-male sex and injecting drugs were the two major risk factors. Complexity of HIV care and lack of reimbursement were the principal barriers to providing HIV care. The burden of providing HIV care is borne by a relatively small number of physicians, and African-American physicians are actively involved in this care. Programs are needed to increase the number of African-American providers treating HIV patients and to provide appropriate reimbursement for providing this care.

Avoiding malpractice for nondental conditions. The example of human immunodeficiency virus.

BACKGROUND: Dentists are legally liable for failing to recognize medical conditions that they identify while providing dental care and for failing to refer patients for follow-up care and testing. This article suggests ways to avoid liability using human immunodeficiency virus, or HIV, infection as an example. TYPES OF LITERATURE REVIEWED: The authors conducted a review of the legal literature to determine circumstances that would cause dentists to have legal liability for failing to recognize a medical problem. The authors also conducted a review of the dental literature to identify the most common signs of HIV infection that dentists might see in practice. RESULTS: The legal literature indicates that dentists can be held liable for failing to recognize medical problems, including HIV and acquired immunodeficiency syndrome. The dental literature shows that there are multiple signs and symptoms that indicate the potential for HIV infection to be the underlying cause of many oral diseases. PRACTICE IMPLICATIONS: Dentists should be familiar with the most common oral manifestations of medical conditions that are likely to be identified in the dental office, including those associated with HIV infection. They must recognize medical conditions and arrange for appropriate referral to avoid liability.

Potential bias in teacher referrals to the school nurse.

Education literature suggests gender, race, and socioeconomic status of students influence the quality and quantity of interactions with their teachers. Studies show that teachers favor White, male, and upper-income children. This preliminary study was conducted to determine if bias was evident in teacher referrals to the school nurse. Referrals from seven elementary schools were studied. The 117 children referred for nonroutine nursing intervention during the nine-week period were compared with 3,787 children not referred. Results showed no differences by gender, but significant differences occurred by socioeconomic status and race (p < .001). When controlling for gender and race, no differences existed between White males and African American males. However, significantly (p < .001) more African American females were referred than White females.

The epidemiology of AIDS/HIV infection: a review for the dentist.

This article reviews 14 recently published articles on the epidemiology of human immunodeficiency virus (HIV) infection. Each article is summarized and evaluated for its usefulness in helping the practicing dentist to perform the various roles of diagnosing and treating disease, managing auxiliary staff, providing community leadership, and educating fellow professionals and patients. Each article was selected based on timeliness, accuracy, and accessibility by a panel of two dental school faculty members, a physician and HIV information specialist, and a school of public health faculty member with extensive experience in HIV and acquired immune deficiency syndrome (AIDS).

HIV/AIDS education survey for mental health professionals.

A total of 6804 mental health professionals, e.g., licensed and certified psychologists, licensed professional counselors, in Arkansas, Louisiana, New Mexico, Oklahoma, and Texas were mailed a questionnaire regarding HIV/AIDS topics professionals might recommend for educational programs. Participants were asked to rate how strongly they would recommend each topic. The return rate was 31% (2121). The percentage of participants who did not recommend the topics was low (0.7%-10.9%). Most topics were either recommended (6.5%-50.2%) or strongly recommended (29.0%-92.8%). Topics with ratings of 80% of participants endorsing the strongly recommended rating included psychological crises associated with learning one is HIV positive, psychosocial issues, and counseling dying clients regarding grief, loss, and legal issues. The results are discussed in terms of continuing to develop educational programs targeting mental health professionals.

Development of indices of effectiveness: a quantification of the accrediting process.

Two indices of effectiveness are described, one of instructional effectiveness and one of administrative effectiveness. Originally, 97 effectiveness measures were obtained from criteria published by national health professional organizations and other accrediting bodies. The Delphi survey process was used to analyze, refine, weight, and select 19 measures of instructional effectiveness and 15 measures of administrative effectiveness. A second article (May 1984) describes the operationalization and quantification of the selected measures and their application to 25 allied health departments in Texas junior and community colleges.

A research approach to simplifying the accrediting process of allied health programs.

The operationalization and quantification of selected measures of effectiveness and their application to 25 allied health departments in junior and community colleges is described. Principal results are that the 34 measures of effectiveness suggested by experts' opinions could be reduced to 14 criteria. These could be combined into two indices of effectiveness, one of instructional effectiveness and one of administrative effectiveness. The results hold promise for simplification of the accrediting process. Part I of this article appeared in the February 1984 issue of JAH.

Inflation and health care costs in metropolitan areas.

This paper reports on an examination of the relationship between increases in health care costs in 23 Standard Metropolitan Statistical areas and various other changes in these communities over the period 1969-1977. The other changes examined consisted of 145 variables divided into 7 categories. The categories were termed demographic, economic, community illness, prices of other goods and services, hospital, physician, and technology factors. The results show that there was little relationship between rates of medical and hospital inflation and the examined variables. Total hospital costs could be related to several of the factors, the most important of which were demographic, economic, and hospital factors.
