The association between preoperative patient characteristics and both clinical and economic outcomes after abdominal aortic surgery.

OBJECTIVE: To evaluate the association between patient characteristics and both clinical and economic outcomes in patients having abdominal aortic surgery in Maryland between 1994 and 1996. DESIGN: Retrospective study using an administrative data set. SETTING: All Maryland hospitals that performed abdominal aortic surgery from 1994 through 1996 (n = 46). PARTICIPANTS: All patients who had abdominal aortic surgery in Maryland from 1994 through 1996 (n = 2,987). INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: The authors obtained discharge abstracts from the Maryland Health Services Cost Review Commission for patients with a primary procedure code for abdominal aortic surgery. Primary outcome variables were in-hospital mortality, hospital length of stay, and intensive care unit (ICU) days. The authors evaluated the following groups of independent variables: demographic characteristics, severity of illness, comorbid disease, and preoperative admission days. In multivariate analysis, independent predictors of in-hospital mortality were age 61 to 70 years (odds ratio [OR], 3.1; confidence interval [CI], 1.4 to 6.9), age 71 to 84 years (OR, 7.2; CI, 3.7 to 14.1), age 85 years or older (OR, 9.3; CI, 3.9 to 21.9), ruptured aneurysm (OR, 5.3; CI, 3.5 to 8.2), urgent operation (OR, 2.3; CI, 1.1 to 5.2), emergent operation (OR, 3.0; CI, 1.9 to 4.7), mild liver disease (OR, 4.6; CI, 2.0 to 10.9), and chronic renal disease (OR, 6.9; CI, 3.9 to 12.1). Hospital admission 1 to 2 days preoperatively was not associated with a difference in in-hospital mortality but was associated with a 31% increase in hospital days (CI, 23% to 40%) and a 38% increase in ICU days (CI, 19% to 60%). CONCLUSION: In patients having aortic surgery, several patient characteristics such as mild liver disease and chronic renal failure, were associated with increased in-hospital mortality and length of stay. The practice of admitting patients to the hospital 1 to 2 days before surgery should be reevaluated because this was not associated with reduced in-hospital mortality but was associated with increased hospital and ICU stay.

Measuring desire for death among patients with HIV/AIDS: the schedule of attitudes toward hastened death.

OBJECTIVE: As physician-assisted suicide is debated, a need for standardized measurement of desire for death among medically ill individuals has emerged. The authors present preliminary validation data for a new self-report instrument, the Schedule of Attitudes Toward Hastened Death. METHOD: The participants were 195 patients with HIV/AIDS from two sites: 148 ambulatory patients and 47 patients who had been recently admitted to a facility for end-of-life care. The ambulatory participants completed the 20-item Schedule of Attitudes Toward Hastened Death and several other instruments, including the Beck Depression Inventory and Brief Symptom Inventory. The terminally ill patients also completed the Schedule of Attitudes Toward Hastened Death, along with other measures, and were assessed by clinicians with the Hamilton Depression Rating Scale and the Desire for Death Rating Scale, a global clinician rating of the patient's desire for death. RESULTS: The Schedule of Attitudes Toward Hastened Death demonstrated high reliability. The total score significantly correlated with the clinician rating on the Desire for Death Rating Scale and with ratings of depression and psychological distress. In addition, the Schedule of Attitudes Toward Hastened Death score significantly correlated with pain intensity and physical symptom distress. Factor analysis supported a single factor structure for the instrument. CONCLUSIONS: These results indicate that the Schedule of Attitudes Toward Hastened Death is a reliable, valid measure of desire for death among patients with HIV/AIDS. Further research with this measure may help address many of the unanswered questions emerging from the ongoing debates regarding legalization of assisted suicide.

Nurses' recognition of depression in their patients with cancer.

PURPOSE/OBJECTIVES: To determine the degree to which nurses recognize levels of depressive symptoms in their patients with cancer and to describe patient characteristics that influence the accuracy of nurses' perceptions of depressive symptoms. DESIGN: Descriptive, prospective correlational design. SETTING: 25 community-based ambulatory oncology clinics affiliated with Community Cancer Care of Indiana. SAMPLE: 40 clinic nurses rated the depression levels of 1,109 patients. METHODS: Patients completed the Zung Self-Rating Depression Scale (ZSDS) prior to their medical oncology clinic appointment. Nurses rated their patients' level of depressive symptoms, anxiety, and pain on a 0-10 numerical scale along with determining a performance status score. MAIN RESEARCH VARIABLES: Patient-rated depression and the nurse depression rating. FINDINGS: The most frequent agreement between nurses and patients was observed when patients reported little or no depressive symptoms. They were only concordant 29% and 14% of the time in the mild and moderate/severe ranges, respectively. Nurses' ratings were influenced most by patients' endorsement of frequent and obvious mood symptoms and nurse ratings of patients' anxiety and pain. CONCLUSIONS: A marked tendency existed to underestimate the level of depressive symptoms in patients who were more severely depressed. Nurses' ratings were most influenced by symptoms such as crying, depressed mood, and medical factors that are useful but perhaps not the most reliable indicators of depression in this population. IMPLICATIONS FOR NURSING PRACTICE: Nurse assessment of depression might be improved if greater emphasis were placed on the more diagnostically reliable symptoms of depression and if screening tools for depression were incorporated into nursing practice.

Patient-related barriers to pain management in ambulatory AIDS patients.

A number of studies have demonstrated that pain is dramatically undertreated among patients with AIDS and that opioids in particular are rarely prescribed. To date, however, there has been no systematic attempt to examine patient-related barriers to the management of pain in AIDS. This study examines potential patient-related barriers to pain management in patients with AIDS using the Barriers Questionnaire (Ward et al., Pain, 52 (1993) 319-324), and assesses gender, racial, and other demographic differences in the endorsement of these barriers. We surveyed 199 ambulatory patients with AIDS, recruited from numerous sites in New York City, as part of an ongoing study of pain and quality of life in ambulatory AIDS patients. In addition to obtaining demographic and medical data, we administered a number of self-report questionnaires including the Brief Pain Inventory (BPI), the Brief Symptom Index (BSI), the Beck Depression Inventory (BDI), and the Memorial Symptom Assessment Scale (MSAS). Barriers to pain management were assessed using a modified version of the Barriers Questionnaire (BQ), including the original 27 questions from this self-report instrument along with an additional 12 items developed for an AIDS population. Results indicated that the most frequently endorsed BQ items were those concerning the addiction potential of pain medications and physical discomfort associated with opioid administration (e.g. injections) or side effects (e.g. nausea, constipation). There were no associations between age, gender, or HIV transmission risk factor and total scores on the BQ; however, Caucasian patients endorsed significantly fewer BQ items than did non-Caucasian patients and years of education was negatively correlated with BQ scores. Scores on the BQ were also significantly correlated with number of physical symptoms (MSAS) and scores on several self-report measures of psychological distress (the BSI Global Distress Index, BDI total scores). Patient-related barriers (i.e. BQ total scores) were significantly associated with undertreatment of pain (as measured by the Pain Management Index), and added significantly to the prediction of undertreatment in a logistic regression analysis, even after controlling for the impact of gender, education and IDU transmission risk factor. These data suggest that patient-related barriers to pain management may add to the already considerable likelihood of undertreatment of AIDS-related pain.

Fatigue in ambulatory AIDS patients.

Although preliminary reports indicate that fatigue is a common symptom of human immunodeficiency virus (HIV) disease, little empirical research has focused on its prevalence or characteristics among patients with acquired immunodeficiency syndrome (AIDS). We assessed the frequency of fatigue and its medical and psychological correlates, in a cross-sectional survey of ambulatory AIDS patients. Ambulatory patients with AIDS who participated in a study of quality life (N = 427) were classified into fatigue/no fatigue groups based on their responses to fatigue items on the Memorial Symptom Assessment Scale (MSAS) and the AIDS physical symptom checklist. Self-report inventories were also administered to assess psychological distress, depressive symptoms, and overall quality of life. Medical information was elicited through clinical interview and review of medical chart. Fifty-four percent of the patients endorsed both of the fatigue items from the MSAS and the AIDS physical symptom checklists, and were classified as having fatigue. Women were significantly more likely to report fatigue than men (chi square = 5.28, df = 1, P < 0.03), and patients reporting homosexual contact as their transmission risk factor were significantly less likely to report fatigue than were patients reporting injection drug use or heterosexual contact (chi square = 5.13, df = 2, P < 0.03). The presence of fatigue was significantly associated with the number of current AIDS-related physical symptoms [t(425) = 8.00, P < 0.0001], current treatment for HIV-related medical disorders (chi square = 12.51, df = 1, P < 0.0001), anemia [t(174) = -2.35, P < 0.02], and pain (chi square = 36.36, df = 1 P < 0.0001). Patients with fatigue also had significantly poorer physical functioning ability [Karnofsky: t(422) = -6.27, P < 0.0001], as well as greater degree of overall psychological distress and lower quality of life [F(5,418) = 23.79, P < 0.0001], as measured by the Brief Symptom Inventory, Beck Depression Inventory, Beck Hopelessness Scale, Functional Living Inventory for Cancer (modified for AIDS), and the MSAS Psychological Distress Subscale. Fatigue is a common symptom in ambulatory AIDS patients and is associated with significant physical and psychological morbidity.

The Network Project: a multidisciplinary cancer education and training program in pain management, rehabilitation, and psychosocial issues.

Despite recent advances in cancer pain management and education, the undertreatment of cancer pain remains a national health problem. In response to the need for interdisciplinary education and training, we have developed "The Network Project" at Memorial Sloan-Kettering Cancer Center. This program includes a 2-week observership in cancer pain management, psychosocial oncology, and cancer rehabilitation. The efficacy of the Network Project Observership Program was evaluated with the use of a knowledge and attitude inventory which contains questions pertaining to cancer pain, psychosocial oncology, and cancer rehabilitation, and follow-up questionnaires completed one year after participation in the program. The knowledge and attitude inventory was completed by each participant both before and after the observership period. Analysis of the 152 observers who participated in the first 3 years of the Network Project's Observership Program demonstrated a significant improvement in knowledge of cancer pain, psychosocial issues, and rehabilitation issues (P < 0.0001). In addition, observers reported a significant increase in their local educational and training activities in the year following participation in the Network Project (P < 0.01). The Network Project, funded by the National Cancer Institute, is an interdisciplinary, multimodal training program which has been demonstrated to be an effective means for improving and disseminating knowledge regarding the multidisciplinary management of pain and psychological distress in cancer patients.

Psychological adjustment and suicidal ideation in patients with AIDS.

This article assesses the psychosocial adjustment to illness and examines the relationship between adjustment and psychosocial and medical variables in 91 ambulatory HIV-infected patients. The 91 subjects were receiving ambulatory medical care in hospitals (Memorial Hospital, New York Hospital, and St. Vincent's Hospital) and in private medical consult (Gay Men's Health Crisis) in New York. The majority (74.5%) of subjects had AIDS. The sample was composed principally of white Roman Catholic homosexual men living alone. However, 49.5% were black or hispanic, 31.9% had intravenous drug use as their HIV risk behavior, 54.9% had past psychiatric history (including illegal drug use), and 22% had previous suicide attempts. Self-report measures of psychological adjustment (Psychological Adjustment to Illness Scale), mood (Brief Symptom Inventory), physical (PHYS) and psychological (PSYCH) symptoms from the Memorial Symptom Assessment Scale-Short Form (MSAS-SF), social support (Social Support Questionnaire-Short Report), suicidal ideation (Scale for Suicide Ideation Self-Report), and measures of disease status (Karnofsky Performance Rating Scale, HIV CDC Classification, and Absolute CD4+ Lymphocyte Count) were used in the study. The average age of subjects was 40 years (SD = 6.80). fifty-two (63.4%) subjects acknowledged some indication of suicidal ideation. Variables that correlated with poor medical adjustment (health-care posture) were current suicide ideation (0.32, p = 0.003), number of psychological symptoms (0.45, p = 0.0001), physical symptoms (0.31, p = 0.006), social support (-0.24, p = 0.03), and satisfaction with the social support received (-0.36, p = 0.001). Poor sexual adjustment was related to current suicide ideation (0.39, p = 0.0004), number of psychological symptoms (0.40, p = 0.0003), satisfaction with the social support received (-0.28, p = 0.01), and number of physical symptoms (0.35, p = 0.002). In patients with a diagnosis of AIDS, the number of psychological symptoms (Beta = 0.29, R2 = 0.07, p = 0.02) and the satisfaction with the social support received (Beta = -0.38, R2 = 0.14, p = 0.003) were clear predictors of poor medical adjustment (health-care posture). Likewise, the predictors of poor sexual adjustment were psychological symptoms (Beta = 0.33, R2 = 0.10, p = 0.003) and suicidal ideation (Beta = 0.40, R2 = 0.10, p = 0.002). The results suggest that suicide ideation is associated with poor adjustment, rather than serving as an adaptive function, as has been suggested by others.

Oncologists' recognition of depression in their patients with cancer.

PURPOSE: This study was performed as part of a large depression screening project in cancer patients to determine the degree of physician recognition of levels of depressive symptoms in cancer patients and to describe patient characteristics that influence the accuracy of physician perception of depressive symptoms. METHODS: Twenty-five ambulatory oncology clinics affiliated with Community Cancer Care, Inc of Indiana enrolled and surveyed 1,109 subjects treated by 12 oncologists. Subjects completed the Zung Self-Rating Depression Scale (ZSDS) and physicians were asked to rate their patients' level of depressive symptoms, anxiety, and pain using numerical rating scales. Subjects' sex, age, primary tumor type, medications, primary caregiver, and disease stage at diagnosis were also recorded. RESULTS: Physician ratings of depression were significantly associated with their patients' levels of endorsement of depressive symptoms on the ZSDS. However, agreement between physicians and patients is most frequently clustered when patients report little or no depressive symptoms. While physician ratings are concordant with patient endorsement of no significant depressive symptomatology 79% of the time, they are only concordant 33% and 13% of the time in the mild-to-moderate/severe ranges, respectively. Physician ratings were most influenced by patient endorsement of frequent and obvious mood symptoms, ie, sadness, crying, and irritability. Physician ratings also appeared to be influenced by medical correlates of patients' level of depressive symptoms (functional status, stage of disease, and site of tumor). Additionally, patients whose depression was inaccurately classified reported significantly higher levels of pain and had higher levels of disability. Physicians' ratings of depression were most highly correlated with physicians' ratings of patients' anxiety and pain. CONCLUSION: Physicians' perceptions of depressive symptoms in their patients are correlated with patient's ratings, but there is a marked tendency to underestimate the level of depressive symptoms in patients who are more depressed. They are most influenced by symptoms such as crying and depressed mood, and medical factors that are useful, but not the most reliable, indicators of depression in this population. Physicians' ratings of their patients' distress symptoms seem to be global in nature--they are highly correlated with anxiety, pain, and global dysfunction. Physician assessment might be improved if they were instructed to assess and probe for the more reliable cognitive symptoms such as anhedonia, guilt, suicidal thinking, and hopelessness. Screening instruments and the use of brief follow-up interviews would help to identify patients who are depressed.

Assessing competence to make treatment decisions.

The legal doctrine of informed consent dictates that all patients must be informed of the procedures, risks and benefits of any recommended treatment and available alternatives, and that patients' decisions must be informed, voluntary and competent. Assessing whether or not one's patient is competent to make treatment decisions, however, is a complex task even for highly trained clinicians. Although all patients are presumed to be competent unless demonstrated otherwise, the rate of incompetence is increased in a number of patient populations such as the elderly, psychotic patients, the mentally retarded and individuals with severe medical disorders (e.g., cancer, AIDS). This paper offers guidelines for assessing the decision-making capacity among medical and psychiatric patients, as well as discussing disposition issues when decision-making abilities are indeed impaired.

Competence to stand trial: clinician reliability and the role of offense severity.

As research strategies for studying competence to stand trial evolve, interest in the decision-making process of clinicians and the factors that may influence the clinical process has grown. This study assesses the reliability of clinical opinions regarding the basis for competence decisions and the influence that severity of the offense has upon the clinical determinations of competence. One-hundred eighty-eight criminal defendants in an outpatient forensic clinic were evaluated by pairs of clinicians (psychiatrists and clinical psychologists). Each clinician was asked to complete a questionnaire regarding the defendant's overall degree of competence on a 0 to 10 rating scale, ability to understand charges and proceedings and ability to assist in one's defense, and the likelihood that the defendant was malingering. Results demonstrated a high degree of reliability not only in clinical determinations of competence (agreement in 187 of 188 cases), but in estimates of overall degree of competence and the basis for findings of competence or incompetence (e.g., the Dusky criteria). Misdemeanor defendants were more likely to be found incompetent to stand trial. However, degree of competence was only associated with offense severity for defendants found incompetent to stand trial. There was no relationship between these variables for competent defendants. These results suggest that clinicians may require a higher degree of competence for defendants charged with more serious offenses, although this process may not apply equally to competent and incompetent defendants. Furthermore, conducting competence interviews jointly appears to increase the concordance of competence opinions.

Pain syndromes and etiologies in ambulatory AIDS patients.

Ambulatory AIDS patients participating in a quality of life study were recruited for an assessment of pain syndromes. Of 274 patients with pain, 151 (55%) consented to the assessment which included a clinical interview, neurologic examination, and review of medical records. The number, type, and etiology of pains were evaluated in terms of risk factors, age, sex, CD4+ lymphocyte count, and performance status. The average number of pains per patient was 2.7 (range, 1-7), yielding a total of 405 pains. The most common pain diagnoses were headache (46% of patients; 17% of all pains), joint pain (31% of patients; 12% of pains), pain due to polyneuropathy (28% of patients; 10% of pains), and muscle pain (27% of patients; 12% of pains). Pathophysiology was inferred for all pain syndromes (except for headache), 45% of pain syndromes were somatic in nature, 15% were visceral, 19% were neuropathic, and 4% were unknown, psychogenic, or idiopathic; 17% of pains were classified as headache, hence pathophysiology could not be determined. Pain resulted from diverse etiologies, including the direct effects of HIV/AIDS-related conditions (30%) pre-existing unrelated conditions (24%), and therapies for HIV/AIDS and related conditions (4%). The latter category, pain related to HIV therapies, occurred in 11% of patients. In 37% of the pains, the etiology could not be determined from the information available. In univariate analyses, lower CD4+ cell counts were significantly associated with polyneuropathy (P < 0.05) and headache (P < 0.05), and female gender was significantly associated with the presence of headache (P < 0.05) and radiculopathy (P < 0.001). These data confirm the diversity of pain syndromes in AIDS patients, clarify the prevalence of common pain types, and suggest associations between specific patient characteristics and pain syndromes. The large proportion of patients who could not be given a diagnosis underscores the need for a careful diagnostic evaluation of pain in this population.

A comparison of pain report and adequacy of analgesic therapy in ambulatory AIDS patients with and without a history of substance abuse.

Concerns are often raised regarding the credibility of patients' report of pain and this concern is heightened among individuals with AIDS, where many patients have a history of injection drug use. This study compared the pain experience, adequacy of pain management and psychological well-being among patients with AIDS who reported a history of injection drug use (IDU) as their HIV transmission risk factor and patients with other HIV transmission risk factors. Five hundred and sixteen ambulatory AIDS patients participating in a quality of life study completed a series of self-report instruments including the Brief Pain Inventory, the Beck Depression Inventory, the Brief Symptom Inventory, the Functional Living Inventory and the Social Support Questionnaire. Results demonstrated that IDU and non-IDU subjects did not differ significantly in their report of pain prevalence, pain intensity or pain-related functional interference. However, IDU patients were significantly more likely to receive inadequate analgesic medications, reported lower levels of pain relief and a greater degree of psychological distress. There was also no difference in report of pain intensity, pain relief or functional interference among patients who acknowledged continued drug use, those who denied any recent drug use and patients participating in a methadone maintenance program. These data support the validity of AIDS patients' report of pain, at least in research settings, and suggest that undertreatment of pain is not restricted to patients who actively abuse drugs.

Perioperative ischemia and cardiac complications in major vascular surgery: importance of the preoperative twelve-lead electrocardiogram.

PURPOSE: To investigate the associations between specific preoperative 12-lead electrocardiogram (ECG) abnormalities, perioperative ischemia, and postoperative myocardial infarction or cardiac death in major vascular surgery. METHODS: Two prospective studies on perioperative myocardial ischemia performed in two tertiary university hospitals were combined to include 405 patients. All preoperative ECGs were analyzed according to the Sokolow-Lyon criteria for left ventricular hypertrophy by investigators who were blinded to the patients' perioperative clinical course. Perioperative myocardial ischemia was detected by continuous ECG recording, and postoperative cardiac complications included myocardial infarction and cardiac death. RESULTS: A total of 19 postoperative cardiac complications occurred (two cardiac deaths and 17 myocardial infarctions). Voltage criteria for left ventricular hypertrophy (78 patients, 19%) and ST segment depression greater than 0.5 mm (98 patients, 24.2%) on preoperative ECGs were both significantly associated with postoperative myocardial infarction or cardiac death (odds ratio, 4.2 and 4.7; p = 0.001 and 0.0005, respectively) and with longer intraoperative and postoperative myocardial ischemia. In each of the two study groups, a preoperative ECG abnormality that involved voltage criteria, ST segment depression, or both (134 patients, 33.1%) was more predictive of postoperative cardiac complications than any other preoperative clinical variable, including a history of myocardial infarction or angina pectoris, diabetes mellitus, pathologic Q-wave by ECG, or preoperative myocardial ischemia. The combined duration of intraoperative and postoperative ischemia and the preoperative ECG with either voltage criteria or ST segment depression were the only independent factors associated with adverse cardiac events by multivariate analysis (p < or = 0.0001 and p = 0.02, respectively). CONCLUSION: Left ventricular hypertrophy and ST segment depression on preoperative 12-lead ECGs are important markers of increased risk for myocardial infarction or cardiac death after major vascular surgery.

The Memorial Delirium Assessment Scale.

We conducted two studies with medically hospitalized cancer and acquired immunodeficiency syndrome (AIDS) patients to assess the reliability and validity of a new measure of delirium severity, the Memorial Delirium Assessment Scale (MDAS). The first study used multiple raters who jointly administered the MDAS to 33 patients, 17 of whom met DSM III-R/DSM IV criteria for delirium, 8 met diagnostic criteria for another cognitive impairment disorder (for example, dementia), and 8 had non-cognitive psychiatric disorders (for example, adjustment disorder). Results indicate high levels of inter-rater reliability for the MDAS (0.92) and the individual MDAS items (ranging from 0.64 to 0.99), as well as high levels of internal consistency (coefficient alpha = 0.91). Mean MDAS ratings differed significantly between delirious patients and the comparison sample of patients with other cognitive impairment disorders or no cognitive impairment (P < 0.0002). The second study compared MDAS ratings of 51 medically hospitalized delirious patients with cancer and AIDS made by one clinician to ratings on several other measures of delirium (Delirium Rating Scale, clinician's ratings of delirium severely) and cognitive functioning (Mini-Mental State Examination) made by a second clinician. Results demonstrated a high correlation between MDAS scores and ratings on the Delirium Rating Scale (r = 0.88, p < 0.0001), the Mini-Mental State Examination (r = -0.91, P < 0.0001), and clinician's global ratings of delirium severity (r = 0.89, P < 0.0001). Thus, our findings indicate that the MDAS is a brief, reliable tool for assessing delirium severity among medically ill populations that can be reliably scored by multiple raters. The MDAS is highly correlated with existing measures of delirium and cognitive impairment, yet offers several advantages over these instruments for repeated assessments which are often necessary in clinical research.

Forensic mental health clinical evaluation: an analysis of interstate and intersystemic differences.

Forensic mental health evaluation systems have undergone major changes during the past two decades, and the variability of service delivery systems across states is significant. We compared assessments of competence to stand trial and criminal responsibility in three states with different systems for forensic mental health evaluations: Michigan, Ohio, and Virginia. Although all three states use comparable legal criteria to judge competence and criminal responsibility, we found large, statistically significant differences among the states in the proportion of defendants referred for evaluation who were assessed as incompetent or not criminally responsible. In addition, significant differences were found in the diagnostic and offense categories of defendants referred for evaluation. Our findings suggest that the structure of a system for providing forensic evaluation services may significantly affect both the group of individuals referred for evaluation as well as evaluation outcome.

Pain in ambulatory AIDS patients. I: Pain characteristics and medical correlates.

The characteristics and impact of pain were evaluated in a prospective cross-sectional survey of 438 ambulatory AIDS patients recruited from health care facilities in New York City. More than 60% of the patients reported 'frequent or persistent pain' during the 2 wks preceding the study. Patients with pain reported an average of 2.5 different pains. On the 0-10 numerical scale of the Brief Pain Inventory (BPI), mean pain intensity 'on average' was 5.4 (SD = 2.2; range = 0-10), and mean pain 'at its worst' was 7.4 (SD = 2.0; range = 1-10). The pain-related functional interference index (sum of the seven item BPI subscale) was 42.6 (SD = 17.2; range = 0.70). Demographic variables were not associated with the presence of pain, but the number of current HIV-related symptoms, treatment for HIV-related infections, and the absence of antiretroviral medications were significantly associated with the presence of pain. Female gender, non-Caucasian race, and number of HIV-related physical symptoms were significantly associated with pain intensity. Presence of pain and increasing pain intensity were significantly associated with greater impairment in functional ability (Karnofsky Performance Status, BPI functional interference index) and physical symptom distress (Memorial Symptom Assessment Scale). Results demonstrate high levels of pain and pain-related functional impairment among patients with AIDS. The presence and intensity of pain are associated with more advanced HIV disease and pain intensity is also associated with demographic factors (gender, race).

Pain in ambulatory AIDS patients. II: Impact of pain on psychological functioning and quality of life.

The relationships among pain, psychological distress and other quality of life concerns were examined through a prospective cross-sectional survey of 438 ambulatory AIDS patients recruited from health care facilities in New York City. In this sample, 274 (62.6%) patients reported frequent or persistent pain during the prior 2 wks. Patients with and without pain completed a questionnaire packet that included measures of psychological symptom distress (Brief Symptom Inventory and the Psychological Distress Subscale of the Memorial Symptom Assessment Scale), depression (Beck Depression Inventory and Beck Hopelessness Scale), social support (Social Support Questionnaire), and overall quality of life (Functional Living Index-Cancer, modified for AIDS). Multivariate analyses (MANOVA, multiple regression) revealed significant associations between the presence and intensity of pain and scores on the measures of psychological distress, depression, hopelessness, and quality of life (P < 0.0001 for most analyses). Perceived adequacy of social support was also significantly associated with lower levels of psychological distress and depression, and better quality of life. These results demonstrate the significant relationships between pain, psychological well-being, and quality of life, and affirm the need to provide adequate treatment of pain in patients with AIDS.

Type III posterior urethral valves: presentation and management.

The clinical and radiographic presentation of infants with type III posterior urethral valves help to distinguish them from patients with the more common type I valves. The diaphragmatic valvular obstruction may make catheterization impossible. Percutaneous cystography can confirm the diagnosis and allow for short-term decompression. The presence of smooth-walled bladders with narrow posterior urethras is unique to type III valves but is not always present. Type III valves present within a spectrum of clinical severity; however, the majority involve significant renal impairment. The prognosis for survival and renal function appears poorer for patients with type III valves than for those with type I valves.
