Effects of childbearing on the natural history of panic disorder with comorbid mood disorder.

This historical prospective study included 22 women with panic disorder. They experienced 45 pregnancies associated with or after their first lifetime episode of panic disorder. Mood disorder predated or was associated with 32 of these pregnancies. The most common effect of pregnancy was No Change in symptoms from baseline during pregnancy and continued No Change postnatally for both panic attacks (n = 22; 49%) and depression (n = 19; 59%). The pattern of panic attack across gestations was consistent for only 5 of 14 multiparae. An interesting observation was that first lifetime onset of panic disorder was common postpartum (n = 4) or post-miscarriage (n = 2). First-onset depression was also common postpartum (n = 4).

Didactic value of the clinical evaluation exercise. Missed opportunities.

The clinical evaluation exercise (CEX), a direct observation of trainees' clinical skills, is a common method of house officer evaluation. During our studies of its reliability, the extent of the CEX's didactic value surfaced. This brief report describes the amount of information passed from the evaluator to the house officer in 73 CEXs. On average, evaluators made eight teaching points in postexamination sessions. However, there were as many points recorded on the CEX forms that evaluators never mentioned. In a subset of CEXs carried out with two observers present, agreement in the teaching points presented to the house officer within the pairs witnessing the same examination was 18%. Positive feedback constituted 9% to 12% of the points presented. Our observations suggest that the more systematic feedback mechanisms may enhance the didactic value of the CEX.

Hospitalized pneumonia. Outcomes, treatment patterns, and costs in urban and rural areas.

OBJECTIVES: To describe discharge rates, geographic and patient characteristics, treatment patterns, costs, and outcomes of patients hospitalized with community-acquired pneumonia (CAP) in Pennsylvania hospitals and compare these patients from rural and urban counties. DESIGN: A retrospective database study. PATIENTS: Adult patients (age > or = 18) with an ICD-9-CM diagnosis of pneumonia discharged from 193 Pennsylvania hospitals (n = 36,222) in 1991 from the MediQual Systems Pennsylvania database. MEASUREMENTS: Patient characteristics included a pneumonia-specific severity index, microbiologic etiology, and a number of comorbid conditions. Treatment indicators included the specialty of the admitting physician, length of stay, admittance to an intensive care unit, and mechanical ventilation. Cost indicators included charges and estimated costs. Outcomes measured were inpatient mortality and discharge disposition. Counties in Pennsylvania were classified into seven urban or rural groups, and patients were classified by the county of residence. RESULTS: The discharge rate for CAP was 4.0 per 1,000 and did not vary systematically across urban or rural counties. Most patients were treated in local hospitals. The average distance between residence and hospital was 5.4 miles and varied with urban or rural classification (range 2.5-9.3 miles). Among CAP patients, 37.8% were at low risk of mortality, with no systematic differences across rural or urban patients with respect to pneumonia severity. Rural patients were more likely to be treated by a family physician and somewhat less likely to be admitted to an intensive care unit or to be mechanically ventilated. Costs of treating rural patients were lower. In-hospital mortality rates, with controls for admission severity, were comparable or better for rural patients than for urban patients. CONCLUSIONS: Patients with CAP are treated in hospitals located in counties similar to ones in which they reside. The cost of treatment was lower for rural patients than for urban patients, but outcomes were not different.

Is syncope a risk factor for poor outcomes? Comparison of patients with and without syncope.

OBJECTIVE: To determine whether syncope, independent of underlying comorbidities, is associated with increased mortality or other cardiovascular outcomes. PATIENTS AND METHODS: A prospective cohort study of patients with syncope and a group of patients without syncope matched with respect to age, gender, site of care (inpatient/ outpatient) and a cardiac disease index at an urban university medical center. Overall mortality, cardiac mortality, cardiovascular outcomes, and occurrence of syncope within 1 year of study enrollment were compared between the groups with Kaplan-Meier rates and Mantel-Cox statistics. RESULTS: The characteristics of 470 patients with syncope and the matched patients without syncope were similar except that the patients without syncope had more cardiac diseases than those with syncope (P = 0.002). Patients with and without syncope had similar rates of 1-year overall mortality (9% versus 11%, P = 0.29) and cardiac mortality (3% versus 6%, P = 0.08). In multivariate analyses, syncope was not a significant predictor of overall or cardiac mortality, but male gender, age > 55 years, and congestive heart failure were. One-year rates for other cardiovascular outcomes (myocardial infarction, congestive heart failure, cardiac arrest with survival, and cerebrovascular events) in patients with syncope were similar to those in patients without syncope (P > or = 0.2 for all comparisons). Patients with syncope had a 20.2% recurrence rate in 1 year as compared with a 2.1% rate for new syncope in patients without prior syncope (P < 0.00001). CONCLUSIONS: Syncope itself is not a risk factor for increased overall and cardiac mortality or cardiovascular events. Underlying heart diseases are risk factors for mortality regardless of whether the patient has syncope or not. The major focus of the evaluation of patients with syncope should be to identify and treat underlying heart diseases.

Psychiatric episodes in women with young children.

An historical cohort study was performed. Subjects were 118 pregnant women or mothers of children of < 3 years who were assessed at presentation to a psychiatric hospital and 5 years later. The relationship of episode onset to childbearing (during pregnancy or within 3 months of birth) was derived from psychiatric records at presentation and retrospectively determined by interview and life-event charting at follow-up. Determining childbearing status from records yielded an error rate of 30% compared with the status derived from direct interview. A change in diagnosis in the ChildBearing-Related Onset Illness (CBROI) category occurred in 50% of subjects. When Research Diagnostic Criteria were applied retrospectively to the presenting episodes, 95% of women with CBROI had affective disorder diagnoses. Clinicians in our intake setting often missed episodes of mania or hypomania in our subjects' histories.

Comparison of a disease-specific and a generic severity of illness measure for patients with community-acquired pneumonia.

OBJECTIVE: To compare the performances of a disease-specific severity of illness index and a prototypical generic severity of illness measure, MedisGroups Admission Severity Groups (ASGs), for patients with community-acquired pneumonia. DESIGN: A retrospective database study. PATIENTS: Adult patients (aged > or = 18 years) with an ICD-9-CM principal diagnosis of pneumonia in 78 MedisGroups Comparative Database hospitals. METHODS: The pneumonia severity of illness index (PSI) was developed to predict hospital mortality using logistic regression analyses in a 70% random sample of study patients. The performances of the PSI and the generic severity measure were assessed among the remaining 30% of patients by comparing observed mortalities within the five PSI and ASG severity classes, and areas under their receiver operating characteristic (ROC) curves. Both the PSI and the generic severity measure were used to estimate the 95% confidence interval of the expected number of deaths in each of the 78 study hospitals. Hospitals with an observed number of deaths outside these limits were identified as outliers. RESULTS: There were 14,199 study patients who had community-acquired pneumonia, and 1,542 (10.9%) died during hospitalization. In comparison with the generic severity measure, the PSI more accurately identified patients at extremely low risk of death, and had a larger area under its ROC curve (0.84 vs 0.79; p < 0.0001). Of the 78 study hospitals, 17 (21.8%) were classified as outliers for mortality by at least one severity adjustment system. Among the 11 low-outlier hospitals, six were classified by the generic severity measure alone, two by the PSI alone, and three by both systems; among the six high-outlier hospitals, one was classified by the generic measure alone, three by the PSI alone, and two by both systems. CONCLUSIONS: The PSI provided more accurate estimates of hospital mortality and classified different hospital outliers for mortality than did the generic severity of illness measure for patients with community-acquired pneumonia.

Psychiatric illnesses in patients with syncope.

PURPOSE: To determine the prevalence of psychiatric disorders among patients with syncope; the relationship between psychiatric disorders and the cause of syncope; and the outcome of syncope patients with psychiatric disorders. PATIENTS AND METHODS: In a prospective cohort study in a university-affiliated medical center, hospitalized and ambulatory patients with syncope underwent a standardized medical and psychiatric evaluation consisting of the Diagnostic Interview Schedule (DIS) sections for somatization, panic, generalized anxiety, major depression disorders, and drug and alcohol dependence and abuse disorders. RESULTS: Of 414 patients who completed the DIS, 82 (20%) met the criteria for at least one of the psychiatric disorders or alcohol/drug disorders. Patients with at least one of the four major psychiatric disorders (n = 58) were more likely to report > or = 4 syncopal events in the past year (odds ratio (OR) 2.5, P < 0.04); and to have prodromal symptoms prior to syncopal events (OR 2.4, P < 0.04) than were patients without psychiatric disorders. Syncope patients with only alcohol/drug disorders (n = 24) were more likely to be male (OR 7.7, P < 0.001) and younger than 65 years old (OR 4.5, P < 0.001) than patients without alcohol/drug disorders. One-year recurrence rate for syncope in patients with any psychiatric diagnosis was 35%, compared to 15% in those without a psychiatric disorder (P < 0.0001). Physicians were able to recognize potential psychiatric or alcohol/drug disorders in 70% of patients with more than one psychiatric disorder, but failed to note or treat 60% of the patients with only one of the assessed disorders. CONCLUSIONS: We recommend screening for psychiatric disorders in patients with unexplained syncope, especially in individuals with recurrent syncope and multiple physical symptoms, or for males who are under 65 years of age.

Effects of postpartum psychiatric illnesses on family planning.

OBJECTIVE: We investigated the relationship between postpartum psychiatric episodes and subsequent family planning. Our hypothesis was that women who had a postpartum illness would plan to have fewer children. METHOD: We conducted a mail survey of members of the self-help group Depression After Delivery (DAD). The membership was asked about changes in family planning after a postpartum illness. Two groups were defined: women who took action to prevent further pregnancies after the illness (CHANGE) and women who did not take action to prevent future pregnancies (NO CHANGE). RESULTS: Among respondents 32 percent changed their family plans after suffering a postpartum illness. Fear of recurrence, effects on the family, treatment costs and severity of the episode manifested by suicide or infanticide attempt, hospitalization, and prescribed medication were reasons given for altering plans. CONCLUSIONS: The postpartum illness dramatically changed some women's reproductive plans. Prevention strategies for these illnesses need to be addressed when women are making decisions about having other children.

Variation in the use of red blood cell transfusions. A study of four common medical and surgical conditions.

This study assessed variation in red cell transfusion practice among adult patients hospitalized with ulcer disease (ULCER), and those undergoing coronary artery bypass grafting (CABG), hip surgery (HIP), or total knee replacement (KNEE). The study design was a retrospective analysis of the 1989 MedisGroups Hospital Comparative Database, and the participants were adult patients presenting for their first admission with ULCER (N = 4,664), CABG (N = 6,812), HIP (N = 4,131) or KNEE (N = 3,042) in the MedisGroups Hospital Comparative Database. Outcome measures were whether a patient was transfused, and the number of units transfused. Logistic regression was used to analyze the decision to transfuse, and linear regression to analyze the number of units transfused. In these analyses, patient characteristics, hospital characteristics, and unique hospital identity were used as independent variables. The percentage of patients transfused was ULCER 50%, CABG 81%, HIP 69%, and KNEE 51%. The range among hospitals in the percentage of patients transfused was ULCER 11% to 76%, CABG 51% to 100%, HIP 36% to 95%, and KNEE 9% to 97%. When only patient characteristics were entered in the linear regression analyses, the R2 values were ULCER 0.33, CABG 0.11, HIP 0.11, and KNEE 0.07. When hospital was added, the R2 increased to ULCER 0.38, CABG 0.29, HIP 0.19, and KNEE 0.20 (P < 0.0001 for the change for all analyses). The results of the logistic regression analyses of the probability of transfusion were similar. There is substantial interhospital variation in the proportion of patients transfused and number of units transfused in the four conditions studied. Patient demographic and clinical characteristics explain a substantial proportion of the variation in transfusion practices for ulcer patients, but little of the variation in the three surgical conditions.

Symptomatology of affective and psychotic illnesses related to childbearing.

Symptom patterns in women with childbearing-related onset illnesses (CBROI) and nonchildbearing-related onset illnesses (NCBROI) were compared. Women with diagnoses of Affective Disorders and Psychoses (n = 762) were divided into four groups: CBROI with psychosis, CBROI with non-psychotic affective illnesses, NCBROI with psychosis, and NCBROI with non-psychotic affective illness. Principal components analysis of 64 symptoms revealed 9 factors. The most dramatic result was the high score for psychotic women with CBROI on the factor cognitive disorganization/psychosis. Psychotic women with CBROI also reported homicidal ideation more frequently. Symptoms of non-psychotic women with CBROI and NCBROI did not differ.

Marital support and remission of treated depression. A prospective pilot study of mothers of infants and toddlers.

Eighteen married mothers of infants and toddlers were evaluated before and after 12 weeks of antidepressant treatment for major depressive disorder. The women were assessed at baseline on Snyder's marital disaffection and disharmony subscales and on selected clinical measures to evaluate these factors as correlates of remission. Remission was defined as a Hamilton Rating Scale for Depression score < or = 7 at week 12. Twelve women remitted; six did not. Nonremitted women reported high disaffection toward their husband, were in an episode of which the onset was not childbirth related (i.e., onset not within 3 months after giving birth), or their youngest child was older than 6 months. Results showed that initial symptom severity was no different for the nonremitted and remitted women. Thus, the relationships between low disaffection, late onset, and not having a child under 6 months and nonremission appear to be independent of initial severity of depressive symptoms.

Validation of a pneumonia prognostic index using the MedisGroups Comparative Hospital Database.

PURPOSE: Our purpose was to validate a previously developed pneumonia-specific prognostic index in a large, multicenter population. PATIENTS AND METHODS: We developed a pneumonia-specific prognostic index in a prospective, multicenter study of 346 patients with clinical and radiographic evidence of pneumonia admitted to 3 Pittsburgh hospitals (the derivation cohort), and validated the index in 14,199 patients with a principal ICD-9-CM diagnosis of pneumonia admitted to 78 hospitals in the 1989 MedisGroups Comparative Hospital Database (the validation cohort). The prognostic index classified patients into five ordered risk classes based on six predictors of mortality: age greater than 65 years, pleuritic chest pain, a vital sign abnormality, altered mental status, neoplastic disease, and high-risk pneumonia etiology. Each patient in the validation cohort was assigned to a risk class by obtaining values for the index's six predictors in the MedisGroups population. The performance of the prognostic index in the derivation and validation cohorts was assessed by comparing hospital mortality rates within each of the index's five prognostic risk classes. RESULTS: The hospital mortality rate was 13.0% in the derivation cohort, and 11.1% in the validation cohort (p = 0.26). The agreement in the risk class-specific mortality rates was striking with the exception of class V: in class I, mortality was 0% in the derivation cohort versus 1% in the validation cohort; in class II, 0% versus 1.1%; class III, 10.9% versus 8.6%; class IV, 21.8% versus 26.2%; and class V, 73.7% versus 37.7%. There were no statistically significant differences in mortality rates within the first four risk classes, which represented the vast majority of patients in the derivation (94%) as well as the validation (98%) cohorts. CONCLUSIONS: These data support the generalizability of a pneumonia-specific prognostic index. This index, which performs exceptionally well in classifying low-risk patients, may help physicians identify patients with community-acquired pneumonia who could safely be managed in the ambulatory setting, or if hospitalized, the patients that could be treated with abbreviated inpatient care.

Fever of nosocomial origin: etiology, risk factors, and outcomes.

OBJECTIVES: To identify the etiologies and risk factors associated with fever of nosocomial origin and compare the outcomes of patients with and without nosocomial fever. DESIGN: A prospective study with a case-control component. SETTING: The three medical services of a university hospital. PATIENTS AND METHODS: We evaluated 100 patients with fever of nosocomial origin. Etiologies were assigned by the consensus of three independent reviewers using Centers for Disease Control guidelines. Predictors of bacterial etiology were identified using logistic regression methods. Controls matched for age (+/- 5 years), sex, and comorbidity were identified for 65 of the nosocomial fever cases. Cases and controls were compared with conditional logistic regression to identify risk factors for fever of nosocomial origin. Cases and controls were followed at 1 month to compare length of stay, mortality, and hospital readmission rates. MEASUREMENTS AND MAIN RESULTS: An etiology was assigned in 81 cases: 51 had bacterial infection, 5 had nonbacterial infection, and 25 had a noninfectious etiology. Multivariate predictors of bacterial infection were the presence of diabetes mellitus (odds ratio [OR] = 5.74; 95% confidence interval of the odds ratio [CI] = 1.61 to 20.40), length of stay to fever onset after admission greater than 10 days (OR = 3.98, CI = 1.04 to 15.22), maximum temperature greater than 38.7 degrees C (OR = 3.37, CI = 1.28 to 8.88), and white blood cell count greater than 10 x 10(9)/L (OR = 4.64, CI = 1.68 to 12.77). Comparison of cases and controls indicated that patients with nosocomial fever had more invasive procedures in the 72 hours preceding enrollment in the study than controls (OR = 1.46, CI = 1.03 to 2.08). Although cases were hospitalized almost twice as long as controls (21.5 versus 12.5 days; p < 0.0001), neither 30-day mortality nor hospital readmission rates differed between cases and controls. CONCLUSION: Nosocomial fever often does not represent nosocomial infection and may constitute a wide variety of other conditions. Since bacterial etiology of fever is a major concern, clinical and laboratory findings can be used to predict patients at high risk for an infectious process. A reduction in the number of invasive procedures may decrease the incidence of nosocomial fever. New-onset nosocomial fever leads to an increase in length of hospital stay but is not a significant predictor of mortality.

Relationship of psychiatric illness to childbearing status: a hospital-based epidemiologic study.

Women who presented to a University psychiatric hospital were categorized into those with childbearing-related onset illness (CBROI, n = 168) and compared to those with non-childbearing-related onset illness (NCBROI, n = 1004). Women with CBROI were an average of five years younger. The two groups did not differ in membership across five major psychiatric diagnostic categories. However, women with CBROI were given the specific diagnosis adjustment disorder with depressed mood more frequently. Anxiety disorders were also common in women with CBROI. Most women with CBROI had the onset of illness during the postpartum period compared to during pregnancy or after pregnancy loss.

New primary nonmelanoma skin cancer in patients with a history of squamous cell carcinoma of the skin. Implications and recommendations for follow-up.

BACKGROUND: Rational follow-up guidelines for skin cancer patients should be based on the risk of three separate events: cancer recurrence, cancer metastasis, and the development of subsequent skin cancers. However, currently no guidelines exist for follow-up of patients with squamous cell carcinoma of the skin (SCC), which take into account all three of these risks. OBJECTIVE: The purpose of this study is to establish rational minimum guidelines for follow-up of patients with SCC. To do this, we first must determine the risk of SCC patients for the development of subsequent skin cancers. Combining these data with previously published data on SCC recurrence and SCC metastasis, we then propose guidelines for follow-up of patients with SCC. METHODS: We followed up 101 SCC patients on a yearly basis for 5 years after treatment and recorded the date and site of subsequent nonmelanoma skin cancers (NMSCs). RESULTS: Thirty percent of SCC patients developed additional SCCs and 52% developed subsequent NMSCs within 5 years of therapy for their first SCC. Patients showing the highest risk of subsequent NMSC were those presenting with multiple SCC, SCC greater than 1 cm in diameter, SCC requiring more than 1 Mohs surgery layer to remove, or SCC occurring on the scalp, ear, nose, or extremities. One hundred percent of subsequent NMSCs were detected by the fourth year of follow-up; 54% of these occurred within the first year of follow-up. CONCLUSION: After combining our data with previously published studies of SCC recurrence and metastasis, we recommend that all patients with SCC be followed up for at least 4 years after treatment. Moreover, because most subsequent NMSCs, SCC recurrences, and SCC metastases developed early in the follow-up period, we recommend that patients be reexamined at least every 3 months during the first year of follow-up and every 6 months thereafter. It must be stressed that these are meant as minimum follow-up guidelines.

Prognosis of patients hospitalized with community-acquired pneumonia.

PURPOSE: Our purpose was to determine which clinical features predict short-term mortality in patients with community-acquired pneumonia. PATIENTS AND METHODS: We conducted a prospective multicenter study of 347 patients hospitalized in Pittsburgh (the derivation cohort) and 253 hospitalized and ambulatory patients in Boston (the validation cohort) with clinical and radiographic evidence of pneumonia. Patients in the derivation cohort underwent an extensive microbiologic evaluation including bacteriologic sputum culture, blood cultures, direct fluorescent antibody testing for Legionella species, and serologic testing for Mycoplasma pneumoniae, Legionella species, and Chlamydia TWAR. RESULTS: The overall mortality was 18% in the derivation cohort and 13.2% in the validation cohort. We identified five independent predictors of mortality in the derivation cohort: pleuritic chest pain (risk ratio, 0.4; 95% confidence interval [CI], 0.17 to 0.99), mental status changes (risk ratio, 2.6; 95% CI, 1.4 to 4.6), a severe vital sign abnormality (risk ratio, 2.1; 95% CI 1.2 to 3.6), neoplastic disease (risk ratio, 5.0; 95% CI, 2.7 to 9.1), and "high-risk" pneumonia etiology (risk ratio, 2.8; 95% CI, 1.6 to 5.0). A mortality index based on these factors accurately classified patients into five risk classes of increasing mortality. In the derivation cohort, the 6-week mortality rates were 0% in class I, 2.9% in class II, 13.1% in class III, 32.7% in class IV, and 89.5% in class V. There was little deterioration in the predictive accuracy of the model when tested in the validation cohort: mortality was 2.2% in class I, 0% in class II, 13.5% in class III, 33.3% in class IV, and 55.6% in class V. CONCLUSIONS: This prognostic classification may help direct triage decisions, assess appropriateness of care, and guide the design and analysis of therapeutic trials in patients with community-acquired pneumonia.
