Predictors of operative mortality and cardiopulmonary morbidity in the National Emphysema Treatment Trial.

OBJECTIVE: We sought to identify predictors of operative mortality, pulmonary morbidity, and cardiovascular morbidity after lung volume reduction surgery. METHODS: Univariate and multivariate logistic regression analyses were performed. Candidate predictors included demographic characteristics, physical condition characteristics, pulmonary function measures, measures of the distribution of emphysema as determined by radiologists and by means of computerized analysis of chest computed tomographic scans, and measures of exercise capacity, dyspnea, and quality of life. End points analyzed were operative mortality (death within 90 days of the operation), major pulmonary morbidities (tracheostomy, failure to wean, reintubation, pneumonia, and ventilator for > or =3 days), and cardiovascular morbidities (infarction, pulmonary embolus, or arrhythmia requiring treatment). RESULTS: Five hundred eleven patients in the non-high-risk group of the National Emphysema Treatment Trial underwent lung volume reduction. The incidence of operative mortality was 5.5%, major pulmonary morbidity occurred in 29.8% of patients, and cardiovascular morbidity occurred in 20.0% of patients. Predictors for these end points are as follows: [table: see text]. CONCLUSIONS: Although lung volume reduction can be performed in selected patients with acceptable mortality, the incidence of major cardiopulmonary morbidity remains high. The lone predictor for operative mortality of lung volume reduction was the presence of non-upper-lobe-predominant emphysema, as assessed by the radiologist. Pulmonary morbidity can be expected in elderly patients who have a low diffusing capacity for carbon monoxide and forced expiratory volume in 1 second. When assessing morbidity, the computer-assisted chest computed tomographic analysis proved useful only in predicting cardiovascular complications.

Late urologic morbidity in 177 consecutive patients after radiotherapy for cervical carcinoma: a longitudinal study.

PURPOSE: To provide longitudinal data on urologic morbidity after radiotherapy and brachytherapy for cervical carcinoma. METHODS AND MATERIALS: Five-year longitudinal urologic morbidity data were recorded from 177 consecutive patients of median age 59 years (range: 22-86 years) with cervical carcinoma receiving radiotherapy with curative intent at the Copenhagen University Hospital, Denmark. FIGO stages (%) were as follows: Stage I (15), Stage II (30), Stage III (54), and Stage IV (1). Late morbidity was calculated as cumulative incidence based on actuarial estimates. RESULTS: The 5-year cumulative incidence based on actuarial estimates of urologic morbidity Grades 1 + 2 + 3, Grades 2 + 3, and Grade 3 were 62%, 32%, and 5%, respectively. Frequencies of urologic morbidity in the 54 recurrence-free survivors at the end of follow-up indicated some reversibility in the case of Grades 1 and 2 morbidity. CONCLUSION: With the longitudinal design used in the present study, a rate of mild and moderate morbidity higher than that found in most of the previously reported literature was observed, giving cause for concern and underlining the importance of further longitudinal studies on this subject, specifically studies that relate to the background urologic morbidity in the female population, as well as to the fact that urologic morbidity might regress.

Occurrence and clinical correlates of psychiatric co-morbidity in delusional disorder.

The present study investigated the occurrence and the clinical correlates of psychiatric co-morbidity in a sample of 64 patients with delusional disorder (DD). Subjects were evaluated with a semi-structured interview for the collection of demographic and clinical features of the disorder; co-morbid axis 1 disorders were determined according to the clinical interview using DSM-IV by Othmer and Othmer. Delusional disorder subjects with and without co-morbid diagnoses were compared to investigate whether the presence of another psychiatric disorder influenced the clinical features of the illness.Seventy-two percent of the subjects had at least one additional lifetime psychiatric diagnosis. High lifetime co-morbidity was found with affective disorders, whose onset generally had been subsequent to the onset of DD. Patients with at least one co-morbid disorder (N = 46) had an earlier age at onset, presented for the first psychiatric consultation at an earlier age, and were younger at index evaluation for this study with respect to patients without co-morbidity (N = 18). Types of DD differed significantly according to the presence/absence of lifetime co-morbid disorders: DD patients with co-morbidity were in most cases persecutory type (54.4%) while DD patients without co-morbidity were mixed type (66.7%). Our data indicate that there is a considerable proportion of patients whose DDr is strictly connected with other co-occurring psychiatric disorders (mainly affective disorders), which exert an influence on the phenomenology of the illness.

Elective pneumonectomy for non-small cell lung cancer: factors affecting early operative mortality and morbidity.

BACKGROUND: The aim of this study was to investigate the factors influencing the morbidity and mortality of the non-small cell lung cancer (NSCLC) cases where pneumonectomy was performed. MATERIAL & METHODS: All 101 patients who had underwent a pneumonectomy for NSCLC between 1994-2001 in our hospital were included in the retrospective study. There were 97 males and 4 females with a mean age of 56+/-9.6. Factors affecting morbidity and mortality were analysed by univariate and multivariate analysis. RESULTS: The morbidity rate was 53% and the mortality rate was 9%. Morbidity was related to cardiopulmonary complications in 40% of the cases. The risk factors for cardiopulmonary morbidity with univariate analysis were age > 60 years (p = 0.004), FEV1 < 2 lt (p = 0.016), early bronchopleural fistula (p = 0.0001), tumour size > 4 cm (p = 0.033), vital capacity < 3.7 lt (p = 0.016), forced vital capacity < 3.5 lt (p = 0.033).. With multivariate analysis the risk factors cardiopulmonary morbidity were age (60 >) (p = 0.012) and tumour size > 4 cm (p = 0.043). The risk factors mortality with univariate analysis were right pneumonectomy (p = 0.025), respiratory morbidity (p = 0.0001), cardiac morbidity (p = 0.002), cell type (Epidermoid CA) (0.047), tumour size > 6 cm (p = 0.036), fluid infusion (p = 0.009), forced vital capacity < 78% (p = 0.039), forced expiratory volume in 1 second < 75% (p = 0.039), PO2 (p = 0.037), PCO2 > 42 mmHg (p = 0.023). CONCLUSION: Among the pneumonectomies performed for NSCLC, the causes of postoperative morbidity were multifactorial, however, multivariate analysis did not show any significant factor affecting the mortality, related to this procedure.

Surgery for morbid obesity. Appraisal of old and new techniques.

Morbid obesity is a serious and sometimes lethal disease of unknown etiology. Nonsurgical treatment has not been successful in producing permanent weight loss. Surgical treatment does reliably result in weight loss but is not a cure and is not indicated for all morbidly obese patients. Jejunoileal bypass, the first operation devised for morbid obesity, usually produces excellent weight loss but has high rates of morbidity and mortality. For this reason, it is not currently advised by most surgeons. Gastric bypass reduces morbidity and mortality without compromising weight loss; however, it is technically more difficult than jejunoileal bypass. The newest operations for morbid obesity are variations of gastroplasty. If correctly performed, they will produce satisfactory weight loss with the lowest morbidity rates of all the operations for morbid obesity. However, long-term results for these procedures are not yet available. Therefore, the ideal operative procedure for morbid obesity has yet to be identified.

Clarifying the relationship between unexplained chronic fatigue and psychiatric morbidity: results from a community survey in Great Britain.

The study examined the associations between several sociodemographic and psychosocial variables and unexplained chronic fatigue in the community before and after adjustment for psychiatric morbidity and determined the prevalence of fatigue and rate of disability resulting from fatigue in the general population. The study is a secondary analysis of 1993 data from a household survey of psychiatric morbidity conducted by the Office for Population Censuses and Surveys in Great Britain. The survey included 12,730 subjects age 16-64 years. Unexplained chronic fatigue was used as the dependent variable in a logistic regression analysis, with various sociodemographic and psychosocial variables and psychiatric morbidity as the independent variables. Psychiatric morbidity was assessed by using the Revised Clinical Interview Schedule. Fatigue was measured by using the fatigue section of the Revised Clinical Interview Schedule. A total of 10,108 subjects agreed to cooperate (79.4% participation rate). The prevalence of unexplained chronic fatigue was 9%. Subjects with psychiatric morbidity had higher rates of fatigue. Adjustment for psychiatric morbidity had a minor effect on the associations between sociodemographic factors and chronic fatigue. After adjustment, older subjects, women, and couples with children had higher rates of fatigue. Single subjects, widowed subjects, adults living with parents, and economically inactive subjects had lower rates of fatigue. Fatigue was associated with considerable disability, but the association between fatigue and psychiatric morbidity explained most of this disability. Unexplained chronic fatigue is a common condition, strongly associated with psychiatric morbidity. The close relationship between fatigue and psychiatric morbidity should not obscure the possibility of differences as well as similarities in their aetiologies.

Preterm premature rupture of membranes is not an independent risk factor for neonatal morbidity.

OBJECTIVE: To evaluate the risk factors for development of neonatal morbidity in cases of preterm premature rupture of membranes (PPROM). METHODS: The study population consisted of 2326 singleton preterm births occurring between 1994 and 1997 at Soroka University Medical Center. The neonatal morbidity included respiratory distress syndrome, intraventricular hemorrhage (grade III-IV), necrotizing enterocolitis, periventricular leukomalacia, bronchopulmonary dysplasia, neonatal pneumonia and sepsis. A cross-sectional study was designed to compare neonatal morbidity between two groups: the study group consisted of patients with PPROM (n = 376) and the comparison group of patients without PPROM (n = 1950). RESULTS: The prevalence of the neonatal morbidity associated with PPROM was 13.0% (49/376). There was no statistically significant difference in neonatal morbidity rates between the PPROM group and the group with intact membranes in any of the birth-weight groups (Mantel-Haenszel weighted odds ratio 1.20; 95% CI 0.80-1.20), or gestational-age groups (Mantel-Haenszel weighted odds ratio 1.03; 95% CI 0.79-1.55). There was no statistically significant difference in neonatal morbidity between patients with PPROM and those with intact membranes according to clinical chorioamnionitis. Congenital anomalies did not influence the neonatal morbidity when comparing patients with and without PPROM (44.4% vs. 32.8%, respectively; p = 0.23). CONCLUSIONS: PPROM was not an independent risk factor for neonatal morbidity in preterm births. Neonatal morbidity was affected mainly by prematurity itself, rather than by the occurrence of PPROM.

Co-morbidity in older patients with COPD--its impact on health service utilisation and quality of life, a community study.

BACKGROUND: co-morbidity has been shown to be an important consideration in COPD with an estimated prevalence of 84%. In the Netherlands, a weak association between health-related quality of life and lung function has been found, with a closer link to co-morbidity. OBJECTIVE: to determine the influence of co-morbidity on quality of life and health service utilisation in older patients with COPD in the community. DESIGN: observational cohort study. SETTING: general practice in the North East of England that has a list size of 8300. PARTICIPANTS: 27 patients aged 70 years or above on the practice COPD register. MEASUREMENTS: data on age and sex, spirometry to confirm the diagnosis of COPD, questionnaires to assess quality of life, activities of daily living (ADLs) and co-morbidity. Health service utilisation was recorded by the number of primary and secondary care attendances in the previous year. RESULTS: 10 had mild, 12 had moderate, and 5 had severe disease. Mean age was 76 years. Quality of life (QOL), co-morbidity and health service utilisation measurements were not significantly different between COPD severity groups. There was a significant positive correlation between increasing co-morbidity and poor QOL (r = 0.45, P < 0.05), and significant negative correlation between co-morbidity and ADL scores (scored inversely), r = -0.54, P < 0.05. Significant negative correlation was found between co-morbidity and primary care attendances (r = -0.41, P < 0.05) and significant positive correlation between worsening QOL and secondary care attendances (r = 0.46, P < 0.05). CONCLUSIONS: co-morbidity has an important part to play in COPD assessment, more accurately reflecting QOL in our population. Health service utilisation did not correlate to forced expiratory volume (FEV1)-defined COPD severity.

Relationship between psychosocial factors and asthma morbidity.

A general practice study was designed to describe certain psychosocial attributes of asthma patients and to relate these to reported asthma morbidity in the previous two years. A postal questionnaire on their respiratory morbidity was completed in September 1983 and again in September 1985 by 207 asthma patients. They then completed a postal questionnaire concerning their attitudes to asthma and level of family support. The findings revealed a marked degree of psychosocial morbidity among patients. Family support showed no significant associations with past or current levels of morbidity, or with changes in morbidity over the previous two years. In contrast, negative attitudes to asthma were correlated with significantly higher levels of morbidity, the strongest associations being found between patients' present attitudes and their most recent level of morbidity. These findings in conjunction with work carried out elsewhere suggest that high levels of asthma morbidity bring about a negative attitude to the condition which in turn contributes towards continuing morbidity.

Cardiovascular disease and psychological morbidity among rheumatoid arthritis patients.

OBJECTIVES: To examine whether patients with rheumatoid arthritis (RA) with co-morbid cardiovascular disease (CVD) have different psychological morbidity (and psychosocial risk factors for it) compared with RA patients without co-morbid CVD. METHODS: Patients with RA and co-morbid CVD (n = 44; hypertension alone for n = 27) were compared with RA patients without CVD (n = 110). Differences in psychological morbidity (depression and anxiety) and psychosocial risk factors for this (arthritis self-efficacy, acceptance, social support and optimism) were examined while controlling statistically for medical and demographic covariates. RESULTS: Groups did not differ on RA duration, RA activity, marital status or socioeconomic status, but RA patients with co-morbid CVD were older, less likely to be female and less likely to be in employment than those without CVD. RA patients with co-morbid CVD had significantly higher depression and were more likely to score above cut-offs for depression than RA patients without CVD. No differences existed in anxiety, although anxiety appeared to be more common than depression. Low optimism was identified as a possible psychosocial risk factor for depression. CONCLUSIONS: RA patients with co-morbid CVD have higher depression than RA patients without CVD; low optimism is a potentially modifiable risk factor that may mediate this difference. RA patients with co-morbid CVD may benefit from systematic screening for depression and targeted intervention if necessary.

Prevalence and predictors of psychosocial morbidity in patients with chronic pruritic skin diseases.

BACKGROUND: Itch is a major symptom of many skin diseases and causes patients considerable distress, adversely affecting quality of life. Feelings of helplessness and lack of control can influence the perceived itch and psychosocial complaints. OBJECTIVES: To determine the prevalence of psychosocial morbidity among patients with pruritic skin diseases, and the influence of itch-related variables, coping strategies, and demographic variables on psychosocial morbidity. PATIENTS AND METHODS: One hundred and sixty-eight patients with pruritic skin diseases from five hospitals in the Netherlands participated in the study. Skin-related psychosocial morbidity was measured with the Adjustment to Chronic Skin Diseases questionnaire (ACS); general psychosocial morbidity was measured with the Symptom Checklist-90 (SCL-90). The frequency and intensity of itching and scratching was recorded in diaries. Itch-related coping was measured with the Itching Cognitions Questionnaire (ICQ). Multiple regression analyses were used. RESULTS: Patients with pruritic skin diseases had higher SCL-90 scores than a healthy Dutch population. All patients had psychosocial complaints as measured with the ACS. Thirty-nine per cent of the variance in skin-related psychosocial morbidity was explained by 'catastrophizing and helpless coping'; another 11% was explained by itching and scratching. Age and sex together explained another 10%. The frequency of itching and scratching (11%), 'catastrophizing and helpless coping' (19%) and skin-related psychosocial morbidity (10%) explained the variance in general psychosocial morbidity. CONCLUSIONS: Patients with a pruritic skin disease have a high level of psychosocial morbidity. Catastrophizing and helpless coping are the most important predictors of psychosocial morbidity, with itching, scratching and demographic variables having a limited influence.

Evaluation of an ultrasonographic score for urinary bladder morbidity in Schistosoma haematobium infection.

An ultrasonographic urinary bladder morbidity score was developed and tested in 510 patients with schistosomiasis haematobia, and then evaluated for screening 1,134 randomly selected children from villages endemic for Schistosoma haematobium. The ultrasonographic urinary bladder morbidity score had four grades ranging from normal to marked thickening of the urinary bladder wall or any polyps or masses. Among both patients and randomly screened subjects, the ultrasonographic score was greater (P = 0.01 and P < 0.01) in males than in females. Children examined in the clinic had higher (P = 0.03) ultrasonographic scores than adults. Infected subjects in communities were more likely (P < 0.001) to have urinary bladder morbidity than uninfected subjects, and clinic patients with egg counts > or = 20 eggs/10 ml of urine had higher (P = 0.03) ultrasonographic urinary bladder morbidity scores than those with lighter infections. The geometric mean egg count was higher (P = 0.04) in clinic patients with grade II and III lesions than in those with grade 0 and I lesions. There was progressive improvement of the grade of urinary bladder morbidity scores in patients treated with praziquantel at each follow-up examination (P < 0.001) and there was a positive relationship (P < 0.01) between urinary bladder morbidity scores and ultrasonographic-detected renal back pressure changes. The ultrasonographic urinary bladder morbidity score objectively measured the severity of urinary bladder morbidity and correlated with intensity of S. haematobium infection in our subjects. It can be used in evaluating both morbidity in patients and in community surveys and in following the outcome of chemotherapy.

[Spatial accumulation of mortality and morbidity from cancer of the prostate (ICD-10:C61)].

The authors examined the spatial accumulation of mortality and morbidity of cancer of the prostate of the total as well as age stratified male population of Hungary. Using GIS, a descriptive epidemiological study was carried out examining the spatial differences of mortality on settlement level with 2000 inhabitants by calculating standardized mortality and morbidity ratios. The significance of the difference of mortality and morbidity from the national mean was tested by chi square probe. On the basis of the results a significant excess in mortality was detected in 11 regions of the country. The unfavourable regions cover 11.6% of the territory of the country where 25.6% of the male population live. A significant excess morbidity can be observed in 8 counties. A significant correlation was found between the unfavourable regions of mortality and morbidity (r=0.443, p<0.05). The age-specific analysis of morbidity revealed the highest excess in morbidity in the age group over 70 years accumulating in 3 counties of Transdanubia and in 6 counties of the Great Plain. On the basis of the results of mortality and morbidity analysis according to age and areas the unfavourable regions can be identified where mortality and morbidity from cancer of the prostate accumulates. These studies serve as a basis for intervention strategies.

Co-morbidity and health outcomes in three Auckland hospitals.

AIMS: To establish the burden of co-morbid disease using the Charlson Index among hospital inpatients and its relationship to key health outcomes. METHODS: An initial screen was carried out on 1575 medical records selected by systematic list sample from admissions for 1995 in three public hospitals in the Auckland region. In the course of the administration of the instrument, screeners were required to record the occurrence of co-morbid disease using the Charlson Index. RESULTS: A third of patients had co-morbid disease, of which chronic pulmonary disease and congestive heart failure were the most frequently recorded. While the Charlson Index was associated with age of patient, length of stay, inpatient mortality, and adverse event status, the simple presence or absence of co-morbidity was as an effective predictor as the extended index. Co-morbidity was more likely to be recorded for Maori, for patients from deprived areas, and for circulatory or respiratory diagnoses. Specific co-morbid conditions were predictive of health outcomes. CONCLUSIONS: Levels of co-morbid disease established for patients using the Charlson Index in three Auckland public hospitals are similar to those recorded internationally. Co-morbidity is predictive of key health outcomes that are of clinical and managerial significance. Controlling for co-morbidity will be important in making comparisons of the quality of care.

Analysis of morbidity and mortality rates in right hepatectomy with the preoperative APACHE II score.

Morbidity and mortality rates in 70 patients who underwent major liver resection for liver tumors (primary and metastatic) were determined and correlated with the preoperative APACHE II score. Patients were divided into three groups according to their preoperative APACHE II score: low (0 to 3), mid (4 to 7), and high (8 and above). A higher score was closely correlated with increased postoperative morbidity and operative mortality rates. The group with low scores had a postoperative morbidity rate of 34% and a mortality rate of 0%, the group with mid scores had a postoperative morbidity rate of 54% and a mortality rate of 3%, and the group with high scores had a postoperative morbidity rate of 80% and a mortality rate of 20%. Age did not correlate with morbidity. It was therefore postulated that morbidity and mortality rates were related to the combination of points for abnormal physiologic variables and points for chronic health, or APACHE II score minus points for age. As the combination of these points increases the postoperative morbidity and operative mortality rates increase significantly (from 24% in the 0-point group to 69% in the greater than or equal to 3-point group). Also the two deaths occurred in the group with 3 or more points. The preoperative APACHE II score may be used by clinicians to evaluate before surgery the risk of postoperative morbidity and death in elective major liver surgery.

Factors influencing neonatal morbidity in diabetic pregnancy.

The influence on neonatal morbidity of factors such as maternal duration of diabetes, third trimester blood glucose control, gestational age at delivery, mode of delivery, and hypertension in pregnancy was analyzed in 92 consecutive diabetic pregnancies (White B35, C22, D26, F9). In a subgroup of 52 diabetic pregnancies the analysis was extended to the influence of hemoglobin A1c at the start and end of pregnancy, blood glucose control during delivery, and fetal insulin secretion at birth. The infants were divided into 3 groups according to the degree of neonatal morbidity: either no (n = 37), minor (n = 27), or severe morbidity (n = 28). There were no significant differences between the groups with no and minor morbidity. Compared to the no-morbidity group, the group with severe morbidity had significantly longer duration of maternal diabetes (p less than 0.05), shorter gestational age at delivery (p less than 0.025), higher frequency of cesarean section (p less than 0.05), and higher frequency of toxicosis (p less than 0.01). The 3 groups did not differ significantly with regard to maternal blood glucose control during pregnancy and delivery. Discriminant analysis revealed that the most significant (p less than 0.001) influence on severe morbidity came from gestational age at delivery. After correction for this factor, there were no other factors with a significant influence on severe morbidity. Within the actual range (mean values 3.9-8.5 mmol/l), blood glucose control during the third trimester had no significant influence on morbidity.

Perioperative morbidity associated with bariatric surgery: an academic center experience.

HYPOTHESIS: As the demand for bariatric surgery increases, it becomes increasingly important to define predictors of morbidity and mortality. We hypothesize that specific clinical variables predict postoperative morbidity after bariatric surgery. DESIGN, SETTING, AND PATIENTS: This is a retrospective review of 452 patients undergoing inpatient bariatric surgery at an academic tertiary care institution. INTERVENTIONS: Patients underwent open or laparoscopic gastric bypass or biliopancreatic diversion with duodenal switch at Oregon Health & Science University, Portland, from 2000 to 2003. Patient data were prospectively entered into a database. MAIN OUTCOME MEASURES: Postoperative morbidity and mortality were analyzed among all patients, and logistic regression was used to identify clinical predictors of morbidity. RESULTS: Major and minor morbidity rates were 10% and 13%, respectively; mortality was 0.9%. Age was associated with postoperative complications (odds ratio = 1.056 for each additional year). Duodenal switch was also associated with higher morbidity than gastric bypass (odds ratio = 2.149). Body mass index, sex, diabetes, surgical approach, and surgeon experience did not predict complications. CONCLUSIONS: Increased age is a predictor of complications after bariatric surgery. Duodenal switch is also associated with a higher morbidity rate than gastric bypass. Surgeons should caution older patients (>/=60 years) of a higher risk of postoperative complications, and a higher risk associated with duodenal switch. Large multicenter studies will be necessary to accurately define other clinical predictors of morbidity and mortality after bariatric surgery.
