Participant Perspectives on the Implementation of a School-Linked Text-Message Intervention to Improve Pediatric Asthma Medication Adherence

Background: Poor adherence to inhaled corticosteroids (ICS) is a significant challenge in pediatric asthma, contributing to health inequities. Text-message reminders for ICS therapy are an evidence-based approach that improves pediatric asthma medication adherence, yet has not been widely adopted into practice, partly due to lack of (1) participant input on design and implementation and (2) use of sustainable community linkages. Remote Asthma Link™ (RAL) seeks to fill this gap as a school-linked text-message intervention wherein parents of children with poorly controlled asthma received daily, 2-way text-message reminders for preventive inhaler use. Responses were shared with school nurses who conducted remote check-ins with families. Enrolled children, largely from underserved backgrounds, experienced improvements in medication adherence and asthma health outcomes. While initial results were promising, we have yet to elicit participant input to refine the protocol for more widespread implementation. Objective: Examine participant perspectives on barriers and facilitators of RAL implementation. Methods: Semistructured interviews were conducted May-June 2022 with intervention participants: 10 parents, 7 school nurses, and 4 pediatric providers (n = 21) until thematic saturation was reached. Interview transcripts were coded using thematic analysis. Results: Several facilitators for RAL implementation were identified, including ease of use and accessibility, personal connection to the school nurse, and receipt of a visual notification for habit formation. Barriers included challenges with school nurses reaching parents, poor understanding of program expectations, and lack of reimbursement structure. Participant-proposed solutions to barriers included utilizing alternate communication methods (eg, social media), educational sessions, and meeting with payors to consider reimbursement models. Conclusion: RAL is a school-linked text-message intervention demonstrating promise in improving outcomes and equity in asthma care. Key implementation facilitators, barriers, and proposed solutions will inform protocol adaptations to promote successful implementation of this and other text-message interventions into clinical practice.

Adolescent cancer prevention in rural, pediatric primary care settings in the United States: A scoping review

Adolescence is a critical period for establishing habits and engaging in health behaviors to prevent future cancers. Rural areas tend to have higher rates of cancer-related morbidity and mortality as well as higher rates of cancer-risk factors among adolescents. Rural primary care clinicians are well-positioned to address these risk factors. Our goal was to identify existing literature on adolescent cancer prevention in rural primary care and to classify key barriers and facilitators to implementing interventions in such settings. We searched the following databases: Ovid MEDLINE®; Ovid APA PsycInfo; Cochrane Library; CINAHL; and Scopus. Studies were included if they reported on provider and/or clinic-level interventions in rural primary care clinics addressing one of these four behaviors (obesity, tobacco, sun exposure, HPV vaccination) among adolescent populations. We identified 3,403 unique studies and 24 met inclusion criteria for this review. 16 addressed obesity, 6 addressed HPV vaccination, 1 addressed skin cancer, and 1 addressed multiple behaviors including obesity and tobacco use. 10 studies were either non-randomized experimental designs (n = 8) or randomized controlled trials (n = 2). The remaining were observational or descriptive research. We found a dearth of studies addressing implementation of adolescent cancer prevention interventions in rural primary care settings. Priorities to address this should include further research and increased funding to support EBI adaptation and implementation in rural clinics to reduce urban-rural cancer inequities.

Locations of COVID-19 vaccination provision: Urban-rural differences

PURPOSE

Our goal was to compare locations of COVID-19 vaccine provision in urban and rural communities over the course of the pandemic.

METHODS

We used the Iowa Immunization Registry Information System (IRIS) to identify the organizations providing COVID-19 vaccines (eg, pharmacies, public health departments, and medical providers). Proportions of first-dose vaccines by organization type and patient census-based statistical area were generated. We calculated Chi-square tests to assess differences among metropolitan, micropolitan, and noncore communities.

FINDINGS

IRIS data revealed that 64% (n = 2,043,251) of Iowans received their first COVID-19 vaccine between December 14, 2020, and December 31, 2022. For metropolitan-dwelling individuals, most first doses were administered at pharmacies (53%), with similar trends observed for micropolitan (49%) and noncore (42%) individuals. The second most common location for metropolitan individuals was medical practices (17%); public health clinics and departments were the second most common provider for micropolitan (26%) and noncore (33%) individuals. These trends shifted over time. In December 2020, hospitals were the most common vaccine provider for everyone, but by December 2022, medical providers were the most common source for metropolitan individuals, and pharmacies were most common for micropolitan and noncore individuals.

CONCLUSIONS

Trends in the type of vaccine provider differentiated metropolitan residents from micropolitan and noncore residents. For the latter groups, local public health departments played a more significant role. Across all groups, pharmacists emerged as a critical vaccine provider. Our findings can be used to plan for seasonal vaccine campaigns as well as potential future mass vaccination campaigns.

Trends in COVID-19 vaccine administration across visit types in a safety net pediatric practice during the first year of authorization

We explored patterns of COVID-19 vaccination across pediatric visit types using electronic health record data from 7/1/2021 through 7/25/2022 in a pediatric safety-net clinic. We generated frequencies and descriptive statistics for patient demographic and vaccine administration variables. Analyses were stratified into age subgroups of 5-to-11-year-olds and 12- to-17-year-olds. 1,409 children received at least one dose of the COVID-19 vaccine and 2,197 doses were administered in this first year of vaccine delivery. Most vaccines given were first doses in the series (45%), followed by second doses (38%), and then booster doses (17%). First doses tended to be given at well-child (42%) or nurse visits (48%), while second doses were almost entirely given at nurse visits (87%) and booster doses at well-child visits (58%). Efforts to optimize COVID-19 vaccination could leverage clinic workflow systems to provide reminder prompts for vaccination for scheduling future doses and identify strategies to facilitate vaccination at non-well child visits, particularly for booster doses.

Unvaccinated Adolescents' COVID-19 Vaccine Intentions: Implications for Public Health Messaging

PURPOSE

COVID-19 vaccine uptake remains low for US adolescents and contributes to excess morbidity and mortality. Most research has assessed parental intention to vaccinate their children. We explored differences between vaccine-acceptant and vaccine-hesitant unvaccinated US adolescents using national survey data.

METHODS

A nonprobability, quota-based sample of adolescents, aged 13-17 years, was recruited through an online survey panel in April 2021. One thousand nine hundred twenty seven adolescents were screened for participation and the final sample included 985 responses. We assessed responses from unvaccinated adolescents (n = 831). Our primary measure was COVID-19 vaccination intent ("vaccine-acceptant" defined as "definitely will" get a COVID-19 vaccine and any other response classified as "vaccine-hesitant") and secondary measures included reasons for intending or not intending to get vaccinated and trusted sources of COVID-19 vaccine information. We calculated descriptive statistics and chi-square tests to explore differences between vaccine-acceptant and vaccine-hesitant adolescents.

RESULTS

Most (n = 831; 70.9%) adolescents were hesitant, with more hesitancy observed among adolescents with low levels of concern about COVID-19 and high levels of concern about side effects of COVID-19 vaccination. Among vaccine-hesitant adolescents, reasons for not intending to get vaccinated included waiting for safety data and having parents who would make the vaccination decision. Vaccine-hesitant adolescents had a lower number of trusted information sources than vaccine-acceptant adolescents.

DISCUSSION

Differences identified between vaccine-acceptant and vaccine-hesitant adolescents can inform message content and dissemination. Messages should include accurate, age-appropriate information about side effects and risks of COVID-19 infection. Prioritizing dissemination of these messages through family members, state and local government officials, and healthcare providers may be most effective.

Understanding Implementation of Evidence-Based Interventions to Address Human Papillomavirus Vaccination: Qualitative Perspectives of Middle Managers

Engaging individuals in middle management positions (eg, nurse or clinic managers) could facilitate implementation of evidence-based interventions (EBIs) to improve uptake of human papillomavirus (HPV) vaccination. Our goal was to understand middle managers' role in and perspectives on implementation of EBIs for HPV vaccination. We conducted qualitative interviews with middle managers in pediatric and family practice clinics. We used constructs from the Consolidated Framework for Implementation Research (CFIR) to design the interview guide and as a coding framework. Participants (n = 19) reported overseeing implementation related to HPV vaccination. Across interviews, CFIR inner setting constructs (eg, structural characteristics and implementation climate) were identified as being both barriers and facilitators. As evidenced in this study, middle managers have a deep understanding of organizational factors, and they have the ability to facilitate implementation efforts related to HPV vaccination. Future efforts could focus on engaging middle managers and leveraging their expertise and understanding of barriers and facilitators.

Pediatricians' perspectives on COVID-19 and HPV vaccine hesitancy

Rises in parental vaccine hesitancy, observed during the COVID-19 pandemic, threaten public health. This is especially concerning for vaccines not typically required for school-entry, such as the vaccines for COVID-19 and human papillomavirus (HPV), both of which also have much lower rates of completion compared to other adolescent vaccines. Pediatricians are well-positioned to address vaccine hesitancy and can offer insights into parents' perspectives in this area. There is evidence that pediatricians' sharing their own vaccine stories may help to address parents' concerns; yet we have little information on pediatricians' or their children's COVID-19 vaccine uptake. To address these gaps, we conducted a cross-sectional survey about Massachusetts pediatricians' behaviors and perspectives on vaccines that face significant resistance: HPV and COVID-19 vaccines. A total of 144 people initiated the survey, and 109 participants were eligible and completed the survey. Participants reported high levels of COVID-19 vaccine uptake for themselves (97%) and their children (98%). Similarities in parents' resistance toward both vaccines were identified: fear of side effects; general vaccine resistance. Pediatricians reported a rise in vaccine hesitancy since the beginning of the COVID-19 pandemic. Future research should focus on identifying strategies to build overall vaccine confidence and streamline these efforts for pediatricians.

Empowering Youth Vaccine Ambassadors to Promote COVID-19 Vaccination in Local Communities: A 7-Step Approach

Despite the availability of COVID-19 vaccines for youth since 2021, vaccine hesitancy has resulted in suboptimal uptake. Public health campaigns that empower local youth ambassadors as trusted messengers who share their personal narratives related to getting vaccinated hold promise for promoting COVID-19 vaccination. We used a seven-step approach to develop, implement, and evaluate a youth-led ambassador campaign to promote COVID-19 vaccine uptake in communities experiencing COVID-19 disparities in Worcester, MA. The seven steps included (1) engaging with key partners; (2) determining a community of focus; (3) identifying trusted sources; (4) determining campaign components; (5) training the vaccine ambassadors; (6) disseminating the campaign; and (7) evaluating the campaign. We trained nine youth as vaccine ambassadors. Ambassadors were guided through self-reflection of motivations for COVID-19 vaccination and the resulting personal narratives became the campaign messaging. English/Spanish vaccine messages developed by youth ambassadors were disseminated through social media platforms (n = 3), radio (n = 2), local TV (n = 2), flyers (n = 2,086), posters (n = 386), billboards (n = 10), and local bus ads (n = 40). Qualitative youth feedback indicate participation in the campaign was a positive and empowering experience which reinforces the importance of engaging youth in public health messaging. Youth empowerment through personal narratives (and storytelling) holds promise for future public health campaigns.

Development and Beta-Testing of the CONFIDENCE Intervention to Increase Pediatric COVID-19 Vaccination

INTRODUCTION

Innovative strategies are needed to improve pediatric COVID-19 vaccination rates. We describe the process for developing a clinic-based intervention, CONFIDENCE, to improve pediatric COVID-19 vaccine uptake and present results of our beta-test for feasibility and acceptability.

METHOD

CONFIDENCE included communication training with providers, a poster campaign, and parent-facing educational materials. We assessed feasibility and acceptability through interviews and measured preliminary vaccine intention outcomes with a pre-post parent survey. Interviews were analyzed using rapid qualitative methods. We generated descriptive statistics for variables on the parent survey and used Fisher's exact test to assess pre-post differences.

RESULTS

Participating providers (n = 4) reported high levels of feasibility and acceptability. We observed positive trends in parents' (n = 69) reports of discussing vaccination with their provider and the parental decision to accept COVID-19 vaccination.

DISCUSSION

Our next steps will be to use more rigorous methods to establish the efficacy and effectiveness of the CONFIDENCE intervention.

Parental perceptions of the COVID-19 vaccine for 5- to 11-year-old children: Focus group findings from Worcester Massachusetts

Vaccine hesitancy is a long-standing public health issue. The present work describes parental perceptions of COVID-19 vaccination for 5- to 11-year-old children, to aid in vaccination efforts. Parents of 5- to 11-year-old children residing in Worcester, Massachusetts, were recruited through community partner outreach to participate in semi-structured focus groups. Focus groups were conducted via Zoom in English (n = 4) and Spanish (n = 3) with a total of 67 parents. Rapid qualitative analysis was used. Most participants were female and of Hispanic ethnicity. Themes included: (1) Trusted sources and influential types of information (e.g. personal COVID-19 vaccine stories from peers and healthcare providers), (2) Motivations for vaccination: health (i.e. protecting children, families, and communities from COVID-19), (3) Motivations for vaccination: social, emotional, and educational (i.e. mitigating related negative effects of COVID-19), (4) Drivers of vaccine hesitancy (e.g. frustration, uncertainty, and confusion), (5) Differentiating vaccine acceptance, hesitancy, and resistance, (6) Needed information. Although this context may be unique to parents of 5- to 11-year-old children from Central Massachusetts, especially those who may be Spanish-speaking, or of Hispanic ethnicity, this work reinforces the need for effective and persistent communication to combat vaccine hesitancy. In describing parents' perceptions toward COVID-19 vaccination in their 5- to 11-year-old children, we contextualize vaccine hesitancy and highlight opportunities for existing evidence-based communication strategies to increase vaccine confidence and uptake in pediatric populations.

Clinician perspectives on pediatric COVID-19 vaccination: A qualitative study in central and western, Massachusetts

We explored perspectives of clinicians in central and western Massachusetts about efforts to vaccinate pediatric patients against COVID-19 as well as best practices and challenges for vaccine delivery. We conducted semi-structured qualitative interviews (n = 16) with family practice and pediatric clinicians between late October and early December 2021. Our interviews addressed: process for vaccination and vaccine promotion, parental receptivity to COVID-19 vaccination, receptivity to other pediatric vaccines, resources needed to support vaccine promotion, and best practices developed to encourage hesitant parents. Using a multi-prong recruitment strategy we invited clinicians to participate in telephone interviews, which were audio-recorded and transcribed. We used rapid qualitative analysis to produce summary templates for each interview which were ultimately combined into a matrix summary. The majority of participants (n = 10) were offering the vaccine in their own clinics, while the remainder cited challenges related to staffing, logistics, and space that prevented them from offering the vaccine. Clinicians reported parents fall into three groups: vaccine-accepting, hesitant but potentially accepting, and refusers. Strategies they identified that worked to encourage hesitant parents were sharing personal vaccine stories, acknowledging parents' fears about the vaccine, and being persistent with the most hesitant parents. Yet resources are needed including educational materials and training in how to have these conversations. While challenges related to staffing and space will be difficult to overcome for clinics to be able to offer vaccination on-site, our results highlight the importance of developing effective messaging strategies and training clinicians in how to integrate them into routine practice.

Factors contributing to missed opportunities for human papillomavirus vaccination among adolescents, ages 11 to 13, in Iowa

Introduction

Rates of human papillomavirus (HPV) vaccination remain low and missed opportunities for HPV vaccination are widespread. Researchers have identified factors related to HPV vaccination, but less is known about missed opportunities.

Methods

We used medical claims data from a large Midwestern insurance provider to explore relationships between adolescent and provider characteristics and missed opportunities for HPV vaccination. We stratified models by initiation status with adolescents who had received one or more HPV vaccinations in one group (n = 6,123) and adolescents with no record of an HPV vaccination in the other (n = 8,107).

Results

There were significant differences in comparisons of all variables between initiators and non-initiators. Notably, non-initiators had lower rates of vaccination for HPV and other adolescent vaccinations, and fewer well-child visits. For all adolescents, birth year, having other recommended vaccines, and number of well-child visits were significantly associated with missed opportunities. Additionally, among initiators, pediatrician as a primary care provider and being in a rural area were significantly associated.

Discussion

Overall, adolescents with greater healthcare utilization had more missed opportunities, indicating that, despite increased numbers of visits, providers are not taking advantage of these opportunities to vaccinate. Future research should prioritize developing a deeper understanding of why these missed opportunities are occurring and implementing new and existing strategies to prevent them. Reducing missed opportunities will help to prevent future HPV-related cancers and the significant morbidity and mortality that they can cause.

School-supervised Asthma Therapy is Associated with Improved Long-Term Asthma Outcomes for Underrepresented Minority Children

Asthma morbidity disproportionately impacts children from low-income and racial/ethnic minority communities. School-supervised asthma therapy improves asthma outcomes for up to 15 months for underrepresented minority children, but little is known about whether these benefits are sustained over time. We examined the frequency of emergency department (ED) visits and hospital admissions for 83 children enrolled in Asthma Link, a school nurse-supervised asthma therapy program serving predominantly underrepresented minority children. We compared outcomes between the year preceding enrollment and years one-four post-enrollment. Compared with the year prior to enrollment, asthma-related ED visits decreased by 67.9% at one year, 59.5% at two years, 70.2% at three years, and 50% at four years post-enrollment (all p-values< 0.005). There were also significant declines in mean numbers of total ED visits, asthma-related hospital admissions, and total hospital admissions. Our results indicate that school nurse-supervised asthma therapy could potentially mitigate racial/ethnic and socioeconomic inequities in childhood asthma.

Feasibility of a combined strategy of HPV vaccination and screening in Mexico: the FASTER-Tlalpan study experience

There has been a noticeable shift in discussions about cervical cancer, moving from prevention to elimination. Interventions such as FASTER, human papillomavirus (HPV) vaccination and HPV screening are innovative intervention strategies which can be utilized to begin a path to elimination. To explore the feasibility of the FASTER strategy, an evaluation was carried out in eight primary health-care centers within the Tlalpan Health-Jurisdiction of Mexico City between March 2017 and August 2018. A mixed methods approach was used to evaluate three components: infrastructure, patient acceptability, and health-care professionals' perceptions. This included checklists of requirements for the infrastructure rollout of FASTER and interviews with women and health-care professionals. Nearly all (93%) of the 3,474 women aged 25-45 years accepted HPV vaccination as part of a combined vaccination and screening program. The main reason for acceptance was prevention, while having doubts about the vaccine's benefits was the main reason for refusal. Most of the 24 health-care professionals had a positive opinion toward HPV vaccination and identified the need to increase dissemination, inform the population clearly and concisely and currently extend the age range for vaccination. The evaluation of eight primary health-care centers showed they had the necessary infrastructure for the development of a joint HPV prevention strategy, but many centers required improvements to become more efficient. Together these findings suggest that although HPV vaccine acceptance was high, there is the need to increase education and awareness among potential vaccine recipients and health-care professionals to implement the FASTER strategy.

Injuries from paintball game related activities in the United States, 1997-2001

OBJECTIVE

To quantify and characterize injuries resulting from paintball game related activities among persons >/=7 years in the United States.

SETTING

Hospitals included in the National Electronic Injury Surveillance System (NEISS); these are composed of a stratified probability sample of all hospitals in the United States with emergency departments.

METHODS

Using NEISS, non-fatal injury data for paintball game related injury cases from 1997-2001 were obtained from emergency department records. Participation estimates used to calculate injury rates were obtained from a yearly survey funded by the National Sporting Goods Association.

RESULTS

An estimated 11 998 persons >/=7 years with paintball game related injuries were treated in emergency departments from 1997-2001, with an annual average rate of 4.5 per 10 000 participants (95% confidence interval 3.3 to 5.7). The paintball game related injury rate was highest for 18-24 year olds (4.9 per 10 000 participants) and most injuries (94.0%) occurred among males. Almost 60% of all injured persons >/=7 years were treated for paintball pellet wounds of which most were to the eye. While 76.9% of injured persons ages 7-17 years were treated for paintball pellet wounds, almost 40% of those >/=18 years were treated for injuries resulting from overexertion or a fall. Lower extremity injuries were also common (23.0%), mostly from overexertion. Most injured persons (95.5%) were treated and released.

CONCLUSIONS

As paintball games become more popular, efforts are needed to increase training, enforce rules, and educate participants about how to stay safe, such as wearing protective eye gear, when engaged in paintball games at home, in a public area, or in a sports field.

Pill taking 'routinization': a critical factor to understanding episodic medication adherence

This exploratory study examines the contextual factors that lead to episodic nonadherence to highly active antiretroviral therapy. Unlike global adherence that refers to the overall probability that a participant will take his or her medication over a given time period, episodic adherence refers to whether an individual took a particular dose (e.g., Saturday morning, 17 September). Semi-structured, qualitative interviews were conducted with a convenience sample of 27 consecutive participants enrolled in ongoing adherence trials who had missed at least one dose of antiretroviral medication during the past 2 days. A qualitative analysis revealed that routinization of pill regimens and factors associated with the participant's ability to maintain these routines (e.g., time of day of scheduled dose; location of participant at time of dose) play an important role in successful adherence. In addition, psychosocial factors such as psychological distress, substance abuse, and active and unpredictable social lives may act as barriers to adherence. Implications for adherence interventions are discussed.

Trends in BB/pellet gun injuries in children and teenagers in the United States, 1985-99

OBJECTIVE

To characterize national trends in non-fatal BB/pellet gun related injury rates for persons aged 19 years or younger in relation to trends in non-fatal and fatal firearm related injury rates and discuss these trends in light of injury prevention and violence prevention efforts.

SETTING

The National Electronic Injury Surveillance System (NEISS) includes approximately 100 hospitals with at least six beds that provide emergency services. These hospitals comprise a stratified probability sample of all US hospitals with emergency departments. The National Vital Statistics System (NVSS) is a complete census of all death certificates filed by states and is compiled annually.

METHODS

National data on BB/pellet gun related injuries and injury rates were examined along with fatal and non-fatal firearm related injuries and injury rates. Non-fatal injury data for all BB/pellet gun related injury cases from 1985 through 1999, and firearm related injury cases from 1993 through 1999 were obtained from hospital emergency department records using the NEISS. Firearm related deaths from 1985 through 1999 were obtained from the NVSS.

RESULTS

BB/pellet gun related injury rates increased from age 3 years to a peak at age 13 years and declined thereafter. In contrast, firearm related injury and death rates increased gradually until age 13 and then increased sharply until age 18 years. For persons aged 19 years and younger, BB/pellet gun related injury rates increased from the late 1980s until the early 1990s and then declined until 1999; these injury rates per 100 000 population were 24.0 in 1988, 32.8 in 1992, and 18.3 in 1999. This trend was similar to those for fatal and non-fatal firearm related injury rates per 100 000 which were 4.5 in 1985, 7.8 in 1993, and 4.3 in 1999 (fatal) and 38.6 in 1993 and 16.3 in 1999 (non-fatal). In 1999, an estimated 14 313 (95% confidence interval (CI) 12 025 to 16 601) cases with non-fatal BB/pellet gun injuries and an estimated 12 748 (95% CI 7881-17 615) cases with non-fatal firearm related injuries among persons aged 19 years and younger were treated in US hospital emergency departments.

CONCLUSIONS

BB/pellet gun related and firearm related injury rates show similar declines since the early 1990s. These declines coincide with a growing number of prevention efforts aimed at reducing injuries to children from unsupervised access to guns and from youth violence. Evaluations at the state and local level are needed to determine true associations.

Association between state level drinking and driving countermeasures and self reported alcohol impaired driving

OBJECTIVES

In 1999, alcohol related motor vehicle crashes in the United States claimed 15786 lives and injured more than 300000 persons. Drinking and driving behavior is shaped by individual and environmental level influences. In this study, the association between each state's driving under the influence of alcohol (DUI) countermeasures and self reported alcohol impaired driving was explored.

METHODS

Mothers Against Drunk Driving's (MADD's) Rating the States 2000 survey, which graded states on their DUI countermeasures from 1996-99, was used as an index of each state's comprehensive DUI prevention activities. Information on alcohol impaired driving from residents of each state was obtained from the 1997 Behavioral Risk Factor Surveillance System (BRFSS) survey. The association between the MADD state grades and alcohol impaired driving was assessed using multiple logistic regression.

RESULTS

Of the 64162 BRFSS respondents who reported drinking any alcohol during the past month, 2.1% of women and 5.8% of men reported at least one episode of alcohol impaired driving in the past month. Those living in states with a MADD grade of "D" were 60% more likely to report alcohol impaired driving than those from states with a MADD grade of "A" (odds ratio 1.6, 95% confidence interval 1.3 to 2.1). The association existed for men and women.

CONCLUSION

These findings suggest that stronger state level DUI countermeasures are associated with lower rates of self reported alcohol impaired driving.

National estimates of non-fatal firearm related injuries other than gunshot wounds

OBJECTIVE

To characterize non-fatal firearm related injuries other than gunshot wounds (non-GSWs) treated in hospital emergency departments in the United States that occur during routine gun handling and recreational use as well as violence related use of a firearm.

METHODS

Cases were identified through the National Electronic Injury Surveillance System (NEISS). During the study period, 1 January 1993 through 31 December 1996, NEISS consisted of a nationally representative sample of 91 hospitals in the United States having at least six beds and providing 24 hour emergency services.

RESULTS

An estimated 65 374, or an average of 16,300 per year, non-fatal, non-GSWs were treated in American hospital emergency departments during the four year study period. Fifty seven per cent of all the non-fatal, non-GSWs were violence related, most of which involved being struck by a firearm. The majority of unintentional non-fatal, non-GSWs were self inflicted and occurred during routine gun handling or recreational use of a firearm; 43% of these injuries resulted from gun recoils.

CONCLUSIONS

Non-fatal, non-GSWs make a notable contribution to the public health burden of firearm related injuries. Firearm related injury prevention programs should focus on not only the reduction of gunshot wounds but also the reduction of unintentional and violence related non-GSWs.

Anisotropy of Surface Roughness on Aluminium Sheet Studied by Atomic Force Microscopy

Atomic force microscope images of aluminium sheet are used to calculate the mean roughness Ra and the root mean square roughness Rq for different directions (theta) across the samples. The angle determined values of Ra(theta) and Rq(theta) are significantly lower in the rolling direction than in any other direction. The results provide a clear demonstration of the vector nature of surface roughness. Local features in an angle determined Ra(theta) profile are also compared with the positions of peaks and valleys in the matching topographical cross-section of the surface running at right angles to theta. It is further found that the distribution of z heights for an imaged sample is usually not Gaussian in shape unless the z heights are measured about mean lines constructed across the surface parallel with the rolling direction. The results are relevant for controlling lubrication performance in the aluminium rolling process.

Alcohol-influenced recreational boat operation in the United States, 1994

BACKGROUND

There were 783 recreational boating fatalities in the United States in 1994. One contributor to this toll is alcohol-influenced operation of boats. Our study objective was to determine the prevalence of alcohol-influenced motor boat operation, and describe its relationship to demographic factors and other risk behaviors.

METHODS

In 1994, a randomly dialed national telephone survey contacted 5238 adult respondents who reported on their operation of motor boats, alcohol use, and other potential injury risk behaviors. Data were weighted to obtain national estimates and percentages.

RESULTS

Of 597 respondents who operated a motor boat in 1994, 31% (206 respondents) reported doing so at least once while alcohol-influenced. Alcohol-influenced operation of a motor boat was significantly more likely among males, individuals between 25 and 34 years of age, and those with greater than a college education. Alcohol-influenced motor boat operation was also more common among those who drove motor vehicles while alcohol-influenced, and those who drove a motor vehicle without using a seat belt.

CONCLUSIONS

To decrease alcohol-influenced boating, new strategies should be developed. Strategies used to decrease drinking and driving motor vehicles may prove adaptable to preventing alcohol-influenced boating. More effective means of monitoring alcohol-influenced boating is needed. Alcohol use by passengers on boats should not be overlooked as a problem.

An intercultural comparison of home case management of acute diarrhea in Mexico: implications for program planners

BACKGROUND

The objective was to assess the extent to which similarities in cultural beliefs and practices related to home management of diarrhea would permit general recommendations to improve the content of health care messages.

METHODS

We studied six communities in Mexico, covering rural and urban conditions, different ethnic groups, and different socioeconomic levels. Systematic data collection relied on open-ended, face-to-face interviews with mothers of children under 5 years of age who had had an episode of diarrhea. Similarities among communities were assessed by means of a quadratic assignment procedure applied to signs, symptoms, and treatment matrices. Significant similarity among most of the communities sustained use of a global composite matrix to represent all communities.

RESULTS

We suggest specific recommendations to promote sound home management of diarrhea based on significant correlations among signs and symptoms with treatments. Signs and symptoms include those promoted by the National Program for the Control of Diarrheal Diseases (diarrhea, fever, vomiting) and others commonly mentioned by mothers (stomach ache, sadness, restlessness, refusal to eat). Similarly, recommendations to use home-based treatments based on beliefs related to their use may include the feeding of rice water, soups, and broth to a child who is sad, or rice-gruel and teas for a child with a fever.

CONCLUSIONS

Our study supports that there are enough similarities among mothers' beliefs and practices for the care of acute diarrhea in childhood to support general recommendations at the program level.

What do sequential behavioral patterns suggest about the medical decision-making process?: modeling home case management of acute illnesses in a rural Cameroonian village

It is well recognized that much of the world's medical care is in the hands of laypeople. In pluralistic medical settings, laypeople choose what to do first, second, third, and fourth from a variety of treatment options. In retrospect, laypeople's choices can be represented as an ordered series of health-related behaviors. A systematic of such sequential data provides insights into caregivers' patterns of resort and suggests a tentative theory for how laypeople make medical choices. This study examines sequences of health-related behaviors from a small, Kom-speaking village in Cameroon. Local residents consider seven health actions, including: delaying initial treatment, using various home remedies or pharmaceuticals, going to a government clinic or a Catholic hospital, and consulting a private nurse or a traditional healer. Researchers visited 88 randomly selected compounds on a weekly basis over a 5-month period. Data were collected on the treatments associated with 429 nonchronic episodes. Analysis of the treatment sequences suggests that residents customarily use delay of treatments as a tactic in the decision-making process. Caregivers were more likely to use home-based treatments and to use them earlier in the treatment sequences than they were to seek treatment from outside the compound. When seeking assistance, caregivers often used traditional healers as a conduit to other outside options. Laypeople used a limited number of unique treatment sequences and avoided the repetition of treatment modalities. Caregivers act as if they were following three basic tenets. They minimize uncertainty by identifying illness types that require particular health actions and by delaying action. They minimize the cost of care by first resorting to treatments that are less expensive and easier to administer or by reducing the number of treatments tried. And laypeople maximize treatment variety in the hopes of finding at least one treatment that helps stop the illness.

Residential smoke alarms and fire escape plans

OBJECTIVE

To estimate the proportion of U.S. homes with installed smoke alarms, smoke alarms on the same floor as occupants' bedrooms, and fire escape plans.

METHODS

The authors analyzed data on smoke alarm use and fire escape planning from a 1994 stratified random telephone survey of 5238 U.S. households.

RESULTS

Respondents from 91% of surveyed households reported the presence of at least one installed smoke alarm, and 94% of respondents reported having an alarm on the same level of the home as their sleeping area. The prevalence of installed smoke alarms varied by highest education level in the household and income level. Sixty percent of all households had designed or discussed a fire escape plan at least once; only 17% of these households had actually practiced one.

CONCLUSIONS

Although overall use of smoke alarms was high, certain population subgroups were less likely to have smoke alarms or to have them installed on the same floor as bedrooms. Fire escape planning, another important safety measure, was somewhat less common, and very few respondents reported having practiced a fire escape plan with the members of their household.

The impact of an elementary school-based violence prevention program on visits to the school nurse

INTRODUCTION

In Tucson, Arizona, an elementary school-based violence prevention program (PeaceBuilders) was implemented during the 1994-1995 school year. Anecdotal evidence from school nurses suggested that children were visiting the nurse less often following the implementation of the program. We examined nurses' logs to assess whether the program had an impact on visits to the school nurse.

METHODS

For the school years 1993-1994 and 1994-1995, the weekly number of nurse visits for all reasons, all injuries, and injuries caused by fights in each of the four PeaceBuilders schools were compared with those for three control schools. As part of a planned evaluation, schools had been matched on demographic factors and randomly assigned as intervention or control schools.

RESULTS

Between 1993-1994 and 1994-1995, the rate of visits/1,000 student days decreased 12.6% in the intervention schools while remaining unchanged in the comparison schools. The same trend was detected for injury-related visits. Rates of fighting-related injuries changed little in the intervention schools but increased 56.0% in the control schools. An analysis of covariance confirmed that injuries and visits to nurses decreased in intervention schools relative to control schools.

CONCLUSIONS

These data indicate that in the intervention schools, injuries and visits to the school nurse decreased over the two-year period and that the intervention may have contributed to this change. They also suggest that visits to the school nurses' office may be a useful tool to evaluate some types of elementary school-based violence prevention programs.

[Ethnography of acute respiratory infections in a rural zone of Mexican highlands]

OBJECTIVE

To identify the terms used by mothers to refer to diseases, signs and symptoms related to acute respiratory illnesses (ARI), alarming signs which should motivate them to seek medical attention, and to describe common home practices of disease care and treatment.

MATERIAL AND METHODS

An ethnographic study was performed in six rural communities of the Mexican central highlands. Interviews were collected from 12 key informers, six mothers of children who had died from ARI and 24 mothers of children younger than five years of age, with several ethnographic techniques to complement information ("triangulation").

RESULTS

The most commonly identified diseases were cold, sore throat, cough, bronchitis, pneumonia and "bronchopneumonia". Key signs to establish diagnosis included nasal discharge, sore throat, cough, head and body ache, fever. "bubbling" chest, general malaise and shortness of breath. Tachypnea was referred to as "strong breathing", "much breathing", "rapid breathing" or "sizzle"; intercostal depression as "the chest sinks", stridor as "chest moan or chest snore", sibilance as "chest snore" and cyanosis as "he turns purple". Home treatments include herbal teas, lemon, green or red tomato or potato applied to the throat externally, as well as creams applied to chest or back. Antibiotic prescription was not common, contrary to antipyretics. Most mothers recognized mild illnesses: severe illnesses were recognized less frequently. When faced with a severe ARI, mothers sought attention firstly at the project clinic, second in frequency with a private physician in the capital of the province and then at the Health Ministry of the district. The reasons to choose these possibilities were mainly proximity and lower costs.

CONCLUSIONS

This information can be useful to improve communication with mothers.

Risk factors for injuries from in-line skating and the effectiveness of safety gear

BACKGROUND

Of the estimated 22.5 million people participating in in-line skating in the United States in 1995, about 100,000 were sufficiently injured so as to require emergency department care. We investigated the effectiveness of wrist guards, elbow pads, knee pads, and helmets in preventing skating injuries.

METHODS

We used data from the 91 hospital emergency departments participating in the National Electronic Injury Surveillance System, a national probability sample of randomly selected hospitals with 24-hour emergency departments. Injured in-line skaters who sought medical attention between December 1992 and July 1993 were interviewed by telephone. We conducted a case-control study of skaters who injured their wrists, elbows, knees, or heads as compared with skaters with injuries to other parts of their bodies.

RESULTS

Of 206 eligible injured subjects, 161 (78 percent) were interviewed. Wrist injuries were the most common (32 percent); 25 percent of all injuries were wrist fractures. Seven percent of injured skaters wore all the types of safety gear; 46 percent wore none. Forty-five percent wore knee pads, 33 percent wrist guards, 28 percent elbow pads, and 20 percent helmets. The odds ratio for wrist injury, adjusted for age and sex, for those who did not wear wrist guards, as compared with those who did, was 10.4 (95 percent confidence interval, 2.9 to 36.9). The odds ratio for elbow injury, adjusted for the number of lessons skaters had had and whether or not they performed trick skating, was 9.5 (95 percent confidence interval, 2.6 to 34.4) for those who did not wear elbow pads. Non-use of knee pads was associated with a nonsignificant increase in the risk of knee injury (crude odds ratio, 2.2; 95 percent confidence interval, 0.7 to 7.2). The effectiveness of helmets could not be assessed.

CONCLUSIONS

Wrist guards and elbow pads are effective in protecting in-line skaters against injuries.

National estimates of nonfatal firearm-related injuries. Beyond the tip of the iceberg

OBJECTIVE

To describe the magnitude and characteristics of nonfatal firearm-related injuries treated in hospital emergency departments in the United States and to compare nonfatal injury rates with firearm-related fatality rates.

DESIGN

Data were obtained from medical records for all firearm-related injury cases identified using the National Electronic Injury Surveillance System (NEISS) from June 1, 1992, through May 31, 1993.

SETTING

NEISS comprises 91 hospitals that are a stratified probability sample of all hospitals in the United States and its territories that have at least six beds and provide 24-hour emergency service.

MAIN OUTCOME MEASURES

Numbers and population rates for nonfatal and fatal firearm-related injuries.

RESULTS

An estimated 99,025 (95% confidence interval [CI], 56,325 to 141,725) persons (or 38.6 per 100,000 population; 95% CI, 22.0 to 55.2) were treated for nonfatal firearm-related injuries in US hospital emergency departments during the study period. The rate of nonfatal firearm-related injuries treated was 2.6 (95% CI, 1.5 to 3.7) times the national rate of fatal firearm-related injuries for 1992.

CONCLUSIONS

Nonfatal firearm-related injuries contribute substantially to the overall public health burden of firearm-related injuries. NEISS can be useful to monitor the number of nonfatal firearm-related injuries in the United States. A national surveillance system is needed to provide uniform data on firearm-related injury morbidity and mortality for use in research and prevention efforts.

The compliance of licensed US child care centers with national health and safety performance standards

The American Public Health Association and the American Academy of Pediatrics recently published health and safety guidelines for child care centers. A survey was conducted to determine the extent to which practices in US child care centers are reflective of these guidelines. Compliance with 16 guidelines ranged from 19.5% to 98.6%, varied considerably by state, and was not consistently associated with selected center characteristics. Prevention efforts should focus on practices for which compliance is low and on those that have the greatest disease- and injury-reducing potential.

Comparison of in-line skating injuries with rollerskating and skateboarding injuries

OBJECTIVE

To describe the estimated relative frequency, types of injuries, and demographic features of people injured while in-line skating, rollerskating, and skateboarding in the United States.

DESIGN

Case series.

SETTING

Emergency department visits to hospitals participating in the National Electronic Injury Surveillance System.

PARTICIPANTS

All persons treated for a product-related injury involving in-line skates, rollerskates, or a skateboard between July 1, 1992, and June 30, 1993.

RESULTS

Approximately 30,863 persons (95% confidence interval, 23,073 to 38,653) were treated for in-line skating injuries during the study period. For every in-line skating injury, approximately 3.3 rollerskating and 1.2 skateboarding injuries occurred (P < .0001). The median age of those injured in these three sports was 15, 12, and 13 years, respectively (P < .0001). Sixty-three percent of injured in-line skaters had a musculoskeletal injury, including 37% with a wrist injury, of which two thirds were fractures and/or dislocations. Five percent of all injured in-line skaters had head injury and 3.5% of the injured in-line skaters required hospitalization.

CONCLUSIONS

In-line skating and skateboarding injuries resulted in a similar number of emergency department visits, but fewer than that for rollerskating injuries. Because wrist fractures were the most common type of injury in all three sports, wrist protection is needed. Head protection by helmets is recommended.
