Respiratory illness in children: do deprived children have worse coughs?

Trends, patterns and causes of respiratory disease mortality among inpatients in Tanzania, 2006-2015

OBJECTIVE

To determine the causes, patterns and trends of respiratory diseases-related deaths in hospitals of Tanzania 2006-2015.

METHODS

Retrospective study involving 39 hospitals. Medical records of patients who died in hospital were retrieved, reviewed and analysed. Sources of data were hospital admission registers, death registers and International Classification of Diseases report forms. Information on demographic characteristics, date of death, the immediate underlying cause of death and co-morbid conditions was collected.

RESULTS

Of the 247 976 deaths reported during the 10-year period, respiratory diseases accounted for 12.92% (n = 32 042). The majority of the respiratory mortality was reported among males (55.9%). Overall median age at death was 31 years with an interquartile range (IQR) of 1-47. Median age at death was significantly higher among males (35 years) than females (28 years) (P < 0.0001). Most deaths (37.8%) occurred in eastern Tanzania. About one-third (31.3%) of all respiratory mortality was reported among under-five children, being among girls than boys (34.3% vs. 28.9%, χ²  = 10.3, P < 0.0001). Adolescent and young adult females (15-29 years) had higher age-standardised mortality rates per 100 000 due respiratory diseases than males. Pneumonia (n = 16 639; 51.9%) and pulmonary tuberculosis (n = 9687; 30.2%) accounted for the majority of deaths due to respiratory diseases. Significantly more females (n = 7665; 54.5%) than males died from pneumonia (n = 8878; 49.8%; χ²  = 8.5, P < 0.0001). By contrast, significantly more males (n = 6024; 34%) than females (n = 3596; 26%; χ²  = 15.5, P < 0.0001) died of tuberculosis. The proportion of death due to tuberculosis declined from 32.8% in 2006-2010 to 7.9% in 2011-2015. However, there was a significant increase in the proportion of death due to pneumonia from 49.6% in 2006-2010 to 53.4% in 2011-2015. Co-morbid conditions contributed to 9.1% (2871/31 628) of all deaths due to respiratory diseases. The most common co-morbid condition was HIV which accounted for 1735 (60.4%) deaths and was more common among males (60.8%; n = 957) than among females (59.7%; n = 764).

CONCLUSIONS

Respiratory diseases account for a substantial proportion of all causes of hospital death in Tanzania. Pneumonia and tuberculosis contribute to more than three quarters of all deaths due to respiratory diseases. Since most major respiratory illnesses are avoidable, it is important to strengthen the capacity of the health delivery system in managing cases of respiratory diseases.

Asthma and protracted bronchitis: who fares better during an acute respiratory infection?

AIM

Acute respiratory infections (ARI) are common in children, and symptoms range from days to weeks. The aim of this study was to determine if children with asthma have more severe ARI episodes compared with children with protracted bronchitis and controls.

METHODS

Parents prospectively scored their child's next ARI using the Canadian acute respiratory illness and flu scale (CARIFS) and a validated cough diary (on days 1-7, 10 and 14 of illness). Children were age- and season-matched.

RESULTS

On days 10 and 14 of illness, children with protracted bronchitis had significantly higher median CARIFS when compared with children with asthma and healthy controls. On day 14, the median CARIFS were: asthma = 4.1 (interquartile range (IQR) 4.0), protracted bronchitis = 19.6 (IQR 25.8) and controls = 4.1 (IQR 5.25). The median cough score was significantly different between groups on days 1, 7, 10 and 14 (P < 0.001). A significantly higher proportion of children with protracted bronchitis (63%) were still coughing at day 14 in comparison with children with asthma (24%) and healthy controls (26%).

CONCLUSION

Children with protracted bronchitis had the most severe ARI symptoms and higher percentage of respiratory morbidity at day 14 in comparison with children with asthma and healthy controls.

Frequent attendance, socioeconomic status and burden of ill health. An investigation in the west of Scotland

OBJECTIVES

To investigate whether associations between frequent attendance in general practice and socioeconomic circumstances remain significant after taking detailed account of underlying ill health, perceived social support and social isolation.

METHODS

Data from a community health survey of 1477 people in their late forties and late sixties living in the West of Scotland were examined for associations between frequent attendance, socioeconomic circumstances, self-reported ill health and social support using logistic regression. The main outcome measure was the probability of being a frequent attender (defined pragmatically after initial review of the distribution as 10+ visits a year) with 95% confidence intervals.

RESULTS

Frequent attendance was significantly associated with: greater numbers of serious conditions reported (adjusted odds ratio 1.47; 99% CI 1.09-1.98); higher levels of anxiety (adjusted OR 1.14; 1.04-1.25); and lower levels of self-assessed health (adjusted OR 0.67; 0.54-0.83). No measures of socioeconomic circumstance or social support remained significantly associated with frequent attendance when the greater burden of ill health in poorer and less well-supported groups was considered.

CONCLUSION

The higher levels of frequent attendance likely to be experienced by general practitioners serving populations in adverse social circumstances are likely to be explained by higher levels of health needs, and not solely by a greater readiness to consult for whatever reason. General practitioners working in deprived areas are likely to have to 'run to keep up' in dealing with such comorbidity, and ways of supporting them in the provision of optimum healthcare need to be considered.

Acute childhood illness at home: the parents' perspective

This critical review of British literature explores the phenomenon of acute childhood illness at home from the parents' perspective. The Literature was searched using four CD-ROM databases: CINAHL, MEDLINE, ASSIA and PSYCHLIT, augmented by hand searching of current journal issues. Sandelowski's (1995) stages of qualitative data analysis were used to develop a rigorous approach to conducting qualitative overviews. The majority of childhood illness is of short duration and takes place in the child's own home. Yet the research which addresses this area is limited. Mothers constantly monitor their child's health, identifying illness as a change in behaviour of the child from their perception of normal. Their usual response to illness is nonprofessional care, including general nursing care and 'over the counter' medicines. When mothers do seek help this is usually from the family doctor. Mothers are often dissatisfied with the help and advice they receive. This is partially explained by the mismatches which occur concerning the perceptions of mothers and of health care professionals regarding appropriate use of services and the needs of these mothers and their children. The literature reviewed indicates a need to address the service users perceptions of the services provided. Areas where further research is required are identified.

Patients' perceptions of medical urgency: does deprivation matter?

BACKGROUND

Consultation behaviour is recognized as having numerous determinants, but patients' perceptions of medical urgency have been neglected as a variable of potential importance.

OBJECTIVES

We aimed to describe the variation in patients' perceptions of medical urgency, and to investigate the influence of socio-economic deprivation on such perceptions. We also aimed to investigate the association between patients' perceptions of urgency and their perception of doctor availability.

METHODS

We carried out a questionnaire survey (incorporating 10 clinical vignettes) of patients attending one of 17 participating practices during a 1-week study period. A medical urgency score was calculated for each patient, and compared for patients sharing similar characteristics. The setting was West Lothian, Scotland.

RESULTS

Patients' perceptions of medical urgency as measured by the urgency score were normally distributed amongst a sample of 4999 patients attending their GP. Whilst socio-economic deprivation was a significant determinant of perceptions of medical urgency, the effect was small and can probably be discounted as an important variable determining such perceptions. An association was observed between patients' perceptions of doctor availability following a non-urgent consultation request and a heightened sense of medical urgency.

CONCLUSIONS

Further work is required to explain the differences in the population with regard to perceptions of medical urgency, and to examine the association between patients' perceptions of the seriousness of symptoms and the urgency of consultation requests.

The potential effects of climate change on winter mortality in England and Wales

In Britain death rates from several important causes, particularly circulatory and respiratory diseases, rise markedly during the colder winter months. This close association between temperature and mortality suggests that climate change as a result of global warming may lead to a future reduction in excess winter deaths. This paper gives a brief introductory review of the literature on the links between cold conditions and health, and statistical models are subsequently developed of the associations between temperature and monthly mortality rates for the years 1968 to 1988 for England and Wales. Other factors, particularly the occurrence of influenza epidemics, are also taken into account. Highly significant negative associations were found between temperature and death rates from all causes and from chronic bronchitis, pneumonia, ischaemic heart disease and cerebrovascular disease. The statistical models developed from this analysis were used to compare death rates for current conditions with those that might be expected to occur in a future warmer climate. The results indicate that the higher temperatures predicted for 2050 might result in nearly 9000 fewer winter deaths each year with the largest contribution being from mortality from ischaemic heart disease. However, these preliminary estimates might change when further research is able to make into account a number of additional factors affecting the relationship between mortality and climate.

Geographic variability in hospital admission rates for respiratory disease among the elderly in the United States

BACKGROUND

The elderly represent a susceptible subpopulation that experiences disproportionate levels of morbidity and mortality from respiratory disease. As a consequence, they are frequently hospitalized for these conditions. Evaluating the geographic distributions of these hospital admissions can provide useful insights concerning patterns in incidence and medical care for respiratory diseases.

METHODS

All hospital admissions for pneumonia, acute respiratory infections, asthma, and chronic obstructive pulmonary disease from the United States for a 6-year period (1984 through 1989) were identified using Medicare admissions records. Age-, race-, and sex-standardized annual admission rates were calculated for each county and spatial clustering of disease specific rates was evaluated using Moran's I statistic. Ecologic analyses were conducted using multiple regression procedures with county-specific measures of average annual temperature, average income, household crowding, median educational level, population density, physicians per capita, and hospital beds per capita together with surrogate measures of cigarette consumption and occupational exposures as predictor variables.

RESULTS

Hospital admission rates in the elderly for all four categories of respiratory disease showed marked regional elevations (p < 0.0001), particularly in the southeast and the northern plains states. Low median education level, low per capita income, and household crowding were all associated with elevated hospital admission rates. Surrogate measures of cigarette consumption were strongly associated with hospital admissions in all four disease groups. Hospital beds per capita demonstrated positive associations with hospital admissions, but the number of physicians per capita exhibited consistent inverse relationships with hospital admissions.

CONCLUSIONS

Hospital admission rates for respiratory diseases among the elderly show marked geographic variation and are associated with regional indicators of socioeconomic status, availability of medical resources, occupational lung disease rates, and smoking.
