Childhood asthma in a rural environment: implications for clinical nurse specialist practice

Socioeconomic disparities in asthma health care utilization, exacerbations, and mortality: A systematic review and meta-analysis

BACKGROUND

Prior studies investigating the effect of socioeconomic status (SES) on asthma health care outcomes have been heterogeneous in the populations studied and methodologies used.

OBJECTIVE

We sought to systematically synthesize evidence investigating the impact of SES on asthma health care utilization, exacerbations, and mortality.

METHODS

We searched Embase, Medline, and Web of Science for studies reporting differences in primary care attendance, exacerbations, emergency department attendance, hospitalization, ventilation/intubation, readmission, and asthma mortality by SES. Study quality was assessed using the Newcastle Ottawa Scale, and meta-analyses were conducted using random-effects models. We conducted several prespecified subgroup analyses, including by health care system (insurance based vs universal government funded) and time period (before vs after 2010).

RESULTS

A total of 61 studies, comprising 1,145,704 patients, were included. Lower SES was consistently associated with increased secondary health care utilization including emergency department attendance (odds ratio [OR], 1.61; 95% confidence interval [CI], 1.40-1.84), hospitalization (OR, 1.63; 95% CI, 1.34-1.99), and readmission (OR, 1.31; 95% CI, 1.19-1.44). Substantial associations were also found between SES and ventilation/intubation (OR, 1.76; 95% CI, 1.13-2.73), although there was no association with primary care attendances (OR, 0.79; 95% CI, 0.51-1.24). We found evidence of borderline significance for increased exacerbations (OR, 1.18; 95% CI, 0.98-1.42) and mortality (OR, 1.12; 95% CI, 0.92-1.37) among more deprived groups. There was no convincing evidence that disparities were associated with country-level health care funding models or that disparities have narrowed over time.

CONCLUSIONS

Patients with a lower SES have substantially increased secondary care health care utilization. We found evidence suggestive of increased exacerbations and mortality risk, although CIs were wide. These disparities have been consistently reported worldwide, including within countries offering universally funded health care systems. Systematic review registration: CRD42020173544.

Examining Social Determinants of Health in Childhood Asthma Management

PURPOSE

Social determinants of health (SDoHs) influence how well a family manages children's asthma. The aim of this study was to examine the influence of SDoHs on family asthma management.

DESIGN

A cross-sectional exploratory study was conducted with 292 children in grades 2 to 5 who had current asthma and their parents to examine associations between SDoHs and the families' asthma management, quality of life, and healthcare utilization.

METHODS

Data were collected from both child and parent. Social determinants of health include the child's race/ethnic group, age, gender, and asthma severity and the family's socioeconomic status and language spoken in the home, and the school was the community-level variable. Parents and children completed asthma management and quality-of-life scales and parents reported on the children's emergency department visits and hospitalizations for asthma.

RESULTS

Worse quality of life was reported by families with lower socioeconomic status and African American children. Asthma severity was associated with parents' asthma management but not children's asthma self-management. Families who spoke Spanish at home had the lowest socioeconomic status yet performed significantly more asthma management than English-speaking families.

CONCLUSIONS

The findings highlight factors the clinical nurse specialist should address in educational interventions.

The Advanced Practice Clinical Nurse Specialist

The clinical nurse specialist (CNS), one of the 4 advanced practice registered nurse (APRN) categories, has a unique role to play in contributing to high-quality patient care and system-level change across multiple health care settings. CNS practice requires advanced knowledge and skills, including specialty expertise, the ability to integrate new knowledge and innovation into the system of care, the ability to consult and collaborate with all health professions, and the mentoring of nursing staff to support and fully implement that new knowledge. The purpose of this article was to describe the role of the CNS, explain the background of the CNS role as it relates to APRN practice, provide current CNS workforce statistics, and share opportunities for hospitals and health systems to strategically use CNSs to advance patient and organizational goals.

Household biomass fuel use, asthma symptoms severity, and asthma underdiagnosis in rural schoolchildren in Nigeria: a cross-sectional observational study

Background

In 2014, the International Study of Asthma and Allergies in Childhood (ISAAC) reported that the highest prevalence of symptoms of severe asthma was found in the low- and middle-income countries (LMICs), including Nigeria. While exposure to biomass fuel use may be an important risk factor in the development of asthma, its association with asthma symptoms severity has not been well-established. The aim of this study is to extend the spectrum of environmental risk factors that may be contributing towards increasing asthma morbidity, especially asthma symptoms severity in rural schoolchildren in Nigeria and to examine possible asthma underdiagnosis among this population.

Methods

Authors conducted a cross-sectional survey in three rural communities in Nigeria. Asthma symptoms were defined according to the ISAAC criteria. Information on the types of household fuel used for cooking was used to determine household cooking fuel status. Asthma symptoms severity was defined based on frequencies of wheeze, day- and night-time symptoms, and speech limitations. Logistic regression analyses were used to explore associations.

Results

A total of 1,690 Nigerian schoolchildren participated in the study. Overall, 37 (2.2%) had diagnosed asthma and 413 (24.4%) had possible asthma (asthma-related symptoms but not diagnosed asthma). Children from biomass fuel households had higher proportion of possible asthma (27.7 vs. 22.2%; p < 0.05) and symptoms of severe asthma (18.2 vs. 7.6%; p = 0.048). In adjusted analyses, biomass fuel use was associated with increased odds of severe symptoms of asthma [odds ratios (OR) = 2.37; 95% CI: 1.16–4.84], but not with possible asthma (OR = 1.22; 95% CI: 0.95–1.56).

Conclusion

In rural Nigerian children with asthma symptoms, the use of biomass fuel for cooking is associated with an increased risk of severe asthma symptoms. There is additional evidence that rural children might be underdiagnosed for asthma.

Enhancing Asthma Self-Management in Rural School-Aged Children: A Randomized Controlled Trial

PURPOSE

To test the effects of 2 modes of delivering an asthma educational intervention on health outcomes and asthma self-management in school-aged children who live in rural areas.

METHODS

Longitudinal design with data collected 4 times over 12 months. The target sample was composed of children in grades 2-5 who had a provider diagnosis of asthma. Elementary schools were stratified into high or low socioeconomic status based on student enrollment in the free or reduced-cost lunch program. Schools were then randomly assigned to 1 of 3 treatment arms: in-school asthma class, asthma day camp, or the attention-control group.

FINDINGS

Sample retention was good (87.7%) and equally distributed by study arm. Improvements in emergency department visits and office visits were related to attending either the asthma class or asthma day camp. Asthma severity significantly decreased in both asthma treatment groups. Other factors such as hospitalizations, parent asthma management, and child asthma management improved for all groups.

CONCLUSIONS

Both asthma class and asthma day camp yielded significant reductions in asthma severity. There were reductions in the emergency department and office visits for the 2 asthma arms, and hospitalizations declined significantly for all groups. Asthma self-management also improved in all groups, while it was somewhat higher in the asthma arms. This may be due to the attention being drawn to asthma management by study participation and the action of completing questionnaires about asthma management, asthma symptoms, and health outcomes.

Evaluating the effect of an asthma self-management intervention for rural families

OBJECTIVE

To present outcomes of an asthma self-management educational intervention delivered to children (grades 2-5) at school and to parents in a home visit.

METHODS

The intervention effectiveness was tested in a 12-month longitudinal study with randomization by elementary schools into treatment and attention-control groups with 183 children who had a diagnosis of asthma. Data were collected at four time points. Change over time was examined with linear mixed models.

RESULTS

Quality of life (QOL), hospitalizations, and emergency department visits improved significantly for all the children. African American and Mexican American children had worse asthma-related QOL than did White children. Asthma management behaviors, asthma self-efficacy, and coping likewise improved with girls improving significantly more than the boys. Significant improvements in inhaler skill and asthma severity were seen in the treatment group children when compared to the control group. Treatment group parents showed significant improvements in home asthma management and self-efficacy.

CONCLUSIONS

The improvement in inhaler skill is an important finding for practitioners as this is a behavior that can be addressed in the clinical setting. The reduction in the treatment group's asthma severity scores may reflect the improvement in medication delivery as their inhaler skill improved. The differential improvement between boys and girls points to the need for testing other formats in asthma education that can address different learning styles. The individualized parent asthma education enabled the intervener to incorporate neighborhood and home environmental information thereby allowing for tailoring of parental instruction.
