Treatment-related morbidity and hospital league tables: experience from a national audit of radiotherapy-induced morbidity in cervical carcinoma.

Data are now available from a U.K. audit of survival and late morbidity following curative radiotherapy for cancer of the cervix treated in 1993. The complication rate per centre ranges from 0 to 67%. Although the frequency of complications following curative radiotherapy for cancer of the cervix might be considered to be an indicator of clinical performance, variation in treatment outcomes can be explained by sampling variability rather than real differences in quality of care. In the present study we have asked the question: could the disparity in complication rates between centres be no more or less than would be expected by chance? Our analysis suggests that this is the case, and for this reason it would be premature to use such outcome data to produce league tables or to assess institutional differences. Thus, ranking centres according to complication rate would not be valid, as the differences in rates observed are probably not significantly different from the national average. It is important that audit data are not used inappropriately and this analysis further highlights the need for reliable prospective collection of clinical information and the importance of considering sampling variability in interpreting the results of such studies.

Studies of respiratory morbidity in rubber workers. Part IV. Respiratory morbidity in talc workers.

Pulmonary function tests, chest x-rays, and respiratory questionnaires were administered to eighty talc workers and 189 non-exposed rubber workers from three rubber tire manufacturing plants. The talc workers, who were exposed to talc at levels below the current threshold limit value (TLV) of 20 mppcf for nonfibrous talc, had a statistically significantly greater prevalence of productive cough and of positive criteria for chronic obstructive lung disease (COLD) than did the control workers. The talc workers with more than 10 years of exposure had significantly decreased residual FEV 1.0. Multiple regression analysis of FEV 1.0 in the talc workers estimated that each year of exposure to talc dust reduced the FEV 1.0 by 26 ml. Talc workers had a clear increase in respiratory morbidity, despite the absence of chest roentgenographic changes. Based on this study, a safe exposure level for talc appears to be 25 mg/m3 as a time-weighted average.

Tinnitus and psychological morbidity: a cross-sectional study to investigate psychological morbidity in tinnitus patients and its relationship with severity of symptoms and illness perceptions.

This study investigates the relationship between tinnitus and psychological morbidity using a cross-sectional survey design from patients of an outpatient audiology department in a typical District General Hospital. The results suggest that a significant number of tinnitus patients suffer from psychological problems both during and more unfortunately after routine treatment for their tinnitus. Anxiety was found to be the main psychological problem. In conclusion, this study suggests that, while further research is needed, many tinnitus patients require psychological treatment and this has implications for the staffing of audiology units in District General Hospitals.

Cross-sectional study of morbidity, morbidity-associated factors and cost of treatment in Ngaoundere, Cameroon, with implications for health policy in developing countries and development assistance policy.

BACKGROUND: In a population-based epidemiological study in Ngaoundere, Cameroon, we studied cross-sectional child morbidity and the cost of necessary investigation and treatment. METHODS: Three teams of two to three health workers visited haphazardly selected households in all major housing quarters. We asked permission to enter for a health survey. Children with cough, fever or weight loss as well as sick adults were offered free-of-charge local hospital examination and treatment. RESULTS: From 177 households with 1777 persons, 51 (2.9%) persons were referred. Thirty-five of them had an undiagnosed disease threatening individual health and in many cases also public health. Seven were hospitalised, including three adults with tuberculosis. Malnutrition was diagnosed in nine small children. Four patients had AIDS, seven had malaria. Average total cost for ambulant patients was 15 USD, for hospitalised patients 110 USD.In the households, almost half of the women 16-50 years of age had no schooling. Two per cent of women and nine per cent of men were daily smokers. Coughing children were more likely than non-coughing children to live in a household with at least one smoker (OR = 3.58, 95% CI 1.72 to 7.46), and they generally lived in more poor households (P = 0.018). Twelve of 16 children with weight loss were referred from households with a high poverty score. CONCLUSIONS: Adult smoking and poverty affect children's health. The cost of hospitalisation or long-lasting therapy is beyond the means of most ordinary families. Diseases with severe consequences for public health, like tuberculosis, AIDS and malaria should have national programs with free, decentralised examination and treatment. Access to generic drugs is important. A major educational effort is needed to improve public health.

WHO systematic review of maternal morbidity and mortality: the prevalence of severe acute maternal morbidity (near miss).

AIM: To determine the prevalence of severe acute maternal morbidity (SAMM) worldwide (near miss). METHOD: Systematic review of all available data. The methodology followed a pre-defined protocol, an extensive search strategy of 10 electronic databases as well as other sources. Articles were evaluated according to specified inclusion criteria. Data were extracted using data extraction instrument which collects additional information on the quality of reporting including definitions and identification of cases. Data were entered into a specially constructed database and tabulated using SAS statistical management and analysis software. RESULTS: A total of 30 studies are included in the systematic review. Designs are mainly cross-sectional and 24 were conducted in hospital settings, mostly teaching hospitals. Fourteen studies report on a defined SAMM condition while the remainder use a response to an event such as admission to intensive care unit as a proxy for SAMM. Criteria for identification of cases vary widely across studies. Prevalences vary between 0.80% - 8.23% in studies that use disease-specific criteria while the range is 0.38% - 1.09% in the group that use organ-system based criteria and included unselected group of women. Rates are within the range of 0.01% and 2.99% in studies using management-based criteria. It is not possible to pool data together to provide summary estimates or comparisons between different settings due to variations in case-identification criteria. Nevertheless, there seems to be an inverse trend in prevalence with development status of a country. CONCLUSION: There is a clear need to set uniform criteria to classify patients as SAMM. This standardisation could be made for similar settings separately. An organ-system dysfunction/failure approach is the most epidemiologically sound as it is least open to bias, and thus could permit developing summary estimates.

Mortality and cancer morbidity in workers from an aluminium smelter with prebaked carbon anodes--Part II: Cancer morbidity.

OBJECTIVE: To investigate associations between cancer incidence and exposure to coal tar pitch volatiles, asbestos, pot emissions (fluorides, sulphur dioxide), heat stress, and magnetic fields in workers from a Norwegian aluminium smelter that operated from 1914 to 1975. METHODS: Cancer incidence between 1953 and 1991 was recorded in a cohort of 1137 men hired between 1922 and 1975. The expected number of cancer cases was calculated from incidence rates in Norwegian men. A job exposure matrix with semiquantitative exposure estimates was used to investigate associations between cumulative exposure estimates was used to investigate associations between cumulative exposure and cancer incidence through exploring temporal relations by considering exposures only within specific time windows. RESULTS: A significant excess of cancer cases, 90 observed v 59.0 expected, was found in workers who had been employed for less than three years. No such excess was found in men with at least three years' employment, with 120 cases observed v 129.7 expected. In this subcohort an association was found between the incidence of bladder cancer and exposure to coal tar pitch volatiles 40 years or more before each person-year under observation, and between incidence of lung cancer and tar exposure 35-50 years before observation. An association was also found between incidence of kidney cancer and exposure to heat stress 20-35 years before observation. CONCLUSIONS: The results support previous findings that exposure to coal tar pitch volatiles in the aluminium industry has been associated with increased risk of bladder and lung cancer. They also add information about temporal relations, suggesting that exposure to tar in this smelter has acted on an early stage in the development of these cancers, followed by a latency period of 30-40 years.

Leptin in morbidly obese patients: no role for treatment of morbid obesity but important in the postoperative immune response.

Despite the current opinion that leptin can no longer be seen as a hormone which could be used therapeutically to prevent an energy surplus (it rather protects the organism for an energy deficit), leptin may still have an impact in clinical medicine. Leptin was shown to have several important functions. The pleiotropic properties of leptin include a regulatory function in the immune system. Reviewing the effects of leptin on different parts of the immune system reveals that the immune system is deregulated in an environment low in leptin. A strong reduction in leptin levels occurs in situations of starvation as seen after bariatric surgery. We postulate the hypothesis that the starvation-induced postoperative decrease of leptin is causative of the more serious course of complications observed after bariatric surgery.
