When one is not enough: prevalence and characteristics of homes not adequately protected by smoke alarms

Working with fire departments to adapt and implement evidence-based programs that increase uptake of smoke alarms: a case-series report

We describe a partnership between an academic injury center and three US fire departments to adapt and implement strategies for promoting smoke alarm programs. Each fire department identified the aims and parameters for a new promotion campaign for their smoke alarm programs. Promotion was directed towards residents in each department’s catchment area who were eligible for the smoke alarm program. All three departments independently elected to use an automated telephone message to promote their smoke alarm programs. Uptake of smoke alarm installation services ranged between .02% and 2% of the calls placed. In Rochester, automated calls were sent to all residential landlines via the city’s non-emergency call center; requests for smoke alarms increased by a factor of 7.5 in the month following the campaign. In Grand Rapids, automated calls were sent to 6% of the households served due to the telecommunications infrastructure; because of the limited reach, the overall number of requests remained unchanged, and the number of callers citing the automated calls was less than the number of requests callers reported were motivated by Grand Rapids’ existing promotion strategies. In Cloquet, the automated calls were broadcast on a rolling basis to geographic clusters of households; although the number of requests remained unchanged, fire district officials were pleased to reduce driving time between appointments which allowed volunteers to offer more home visit appointments. Automated telephone calls can be a valuable tool for promoting smoke alarm programs, but fire departments should carefully identify how dissemination strategies can best complement existing program efforts.

It Is Not the Batteries! Smoke Alarm Presence and Functionality 5 to 7 Years Postinstallation of Sealed Lithium Battery Alarms

Smoke alarms with lithium batteries have been marketed as long life or "10-Year Alarms." Previous work has drawn into question the actual term of functionality for lithium battery alarms. This article reports on observed smoke alarm presence and functionality in a sample of 158 homes that had participated in a fire department smoke alarm installation program 5 to 7 years prior to the observations. A total of 391 alarms were originally installed in the 158 homes that completed the revisit. At the time of the revisit, 217 of those alarms were working (54%), 28 were nonworking (7%), and 146 were missing (39%). Of the 158 homes that completed the revisit, n = 62 (39%) had all their originally installed project alarms up and working at the revisit. Respondents who reported owning their homes or who reported living in their home for 6 or more years were significantly more likely to maintain all of their project alarms than renters or those living in their homes for 5 or fewer years. Smoke alarm installation programs should consider revisiting homes within 5 to 7 years postinstallation to inspect and replace any missing or nonfunctioning alarms. We recommend programs conducting community risk reduction programs track and plan installations and revisits to improve smoke alarm coverage.

Firearm Storage and Adult Alcohol Misuse Among Washington State Households With Children

IMPORTANCE

Firearm injuries and fatalities among children are an important public health problem. Children living with an adult misusing alcohol may be at a heightened risk for self-harm or unintentional injury, highlighting the need to investigate the association between household firearm storage and adult alcohol misuse.

OBJECTIVES

To characterize household firearm presence among children by various sociodemographic characteristics, and to assess the association between children living in a home with an unsafely stored firearm and an adult reporting alcohol misuse.

DESIGN, SETTING, AND PARTICIPANTS

This cross-sectional investigation uses data from the 2013 and 2016 Behavioral Risk Factor Surveillance System in the state of Washington, a program that administers a telephone survey statewide to randomly selected noninstitutionalized adults at least 18 years of age about their health-related risk behaviors, chronic health conditions, and use of preventive services. The 2013 and 2016 data included 5241 responses to the firearm ownership and storage module and the Random Child Selection module (intended for a randomly selected child younger than age 18 years and reported by an adult living in the same household). Data for this study were collected from January 1 through December 31, 2013, and January 1 through December 31, 2016. Data were analyzed from March through May 2018.

MAIN OUTCOMES AND MEASURES

The primary outcomes were a child's residence in a firearm-owning home, the manner in which household firearms were stored, and the adult respondent's alcohol consumption.

RESULTS

Among the 3443 children living in a non-firearm-owning household, 50.7% were male (all values given as a percentage only are weighted); among those reporting specific age, the weighted mean age was 9.3 years (unweighted mean [SD], 10.1 [5.2] years). In the 1756 children living in a firearm-owning household, 52.5% were male; among those reporting specific age, the weighted mean age was 9.1 years (unweighted mean [SD], 9.8 [5.4] years). An estimated 470 000 children (29.4%; 95% CI, 27.3%-31.7%) in the state resided in a firearm-owning household. Among them, 258 000 children (54.6%; 95% CI, 51.5%-57.6%) lived with at least 1 firearm that was not stored safely (ie, not locked and unloaded). Firearms were more likely to be stored unsafely in homes in which an adult reported alcohol misuse (prevalence ratio: 1.20; 95% CI, 1.07-1.35).

CONCLUSIONS AND RELEVANCE

Children living in a household with an adult who misuses alcohol may be more likely to live with an unsafely stored firearm, which is concerning given the association between adult alcohol misuse and children's risk for sustaining injury.

Predictors of Participation in a Fire Department Community Canvassing Program

An urban fire department has been distributing free smoke alarms for more than 30 years. A community-academic partnership was developed to conduct a community intervention trial as part of the fire department's home visiting program. The trial comprised 170 canvassing events held across 12 census tracts; half of the census tracts were assigned to the treatment condition and received prepromotion of the home visit events. The objectives of this analysis were to identify environmental and programmatic predictors of 1) whether someone would be at home at the time of a visit, and 2) if at home, whether the resident would participate. A separate multilevel analysis was conducted to address each objective. The canvassing event served as the first level to account for variation in implementation of the program, with the census tract as the second level. All environmental and program characteristics were included as fixed effects in both models. Throughout 170 events, 8080 eligible residential addresses were visited, of which 3216 had someone at home, and 2197 homes participated in the program. Canvassing events held on weekends and during the evening hours was associated with higher odds of a resident being at home. Canvassing events without rain and held in the treatment census tract areas was associated with higher odds of resident participation. Environmental and programmatic factors can impact the reach of home visiting programs. These findings can contribute to emerging best practices for fire department home visiting programs.

How the science of injury prevention contributes to advancing home fire safety in the USA: successes and opportunities

BACKGROUND

In the decades since the landmark report-America Burning-was published in 1973, the number of home fire deaths has shrunk from >5500 per year to 2650 in 2015. This paper: (1) describes how science and practice in injury prevention and fire and life safety contributed to successful interventions, and (2) identifies emerging strategies and future opportunities to prevent home fire-related deaths.

METHODS

The aims are addressed through the lens of population health research, with a focus on the work of selected Centers for Disease Control and Prevention-funded Injury Control Research Centers. Results are organised using the Haddon Matrix and an ecological model.

RESULTS

We found evidence to support interventions that address all components of both the matrix and the model, including: reduced ignition propensity cigarettes, stop smoking campaigns, housing codes, residential sprinkler systems, smoke alarms, community risk reduction, school-based educational programmes, and fire and burn response systems. Future reductions are likely to come from enhancing residential sprinkler and smoke alarm technology, and increasing their utilisation; expanding the use of community risk reduction methods; and implementing new technological solutions. Despite the successes, substantial disparities in home fire death rates remain, reflecting underlying social determinants of health.

CONCLUSION

Most of the evidence-supported interventions were focused on changing the policy and community environments to prevent home fires and reduce injury when a fire occurs. Future prevention efforts should give high priority to addressing the continued disparities in home fire deaths.

Pilot Study of a Novel Partnership for Installing Smoke Alarms

Objectives To demonstrate the feasibility of partnering fire department personnel and home visiting nurses to increase the number of low-income homes protected by smoke alarms. Methods During a regularly scheduled home visit, nurses at the Nurse-Family Partnership of Maricopa County (NFP) informed their clients about an opportunity to have smoke alarms installed in their homes for free. For interested families, nurses sent a referral to the Phoenix Fire Department (PFD), scheduled an appointment, and accompanied the PFD volunteers during the installation. During the appointment, PFD personnel installed alarms and provided safety education. Clients completed a follow-up survey 1-3 months after the installation visit. In-depth interviews were completed with key informants from NFP and PFD to solicit feedback on the program. Results Fifty-two smoke alarm installation visits were completed. Before the fire department arrived, 55% of homes had no working smoke alarm. Almost all (94%) homes received at least one new smoke alarm, and every home had at least one working smoke alarm at the end of the fire department visit. At follow-up, all homes maintained at least one working smoke alarm. Members from both organizations were enthusiastic about, and supportive of the project. NFP nurses appreciated the skill and knowledge of the firefighters; PFD representatives noted that the nurses' relationships with clients made it easier for them to gain access to families who are often described as "hard-to-reach". Conclusions Partnering home visiting nurses and fire departments can be successful to increase the number of vulnerable homes with smoke alarms.

Carbon Monoxide Alarm and Smoke Alarm Use Among Parents Recruited From a Pediatric Emergency Department

Although the proper installation and maintenance of carbon monoxide (CO) and smoke alarms can protect individuals from residential CO-related and fire-related injuries, these devices are underutilized. We describe characteristics associated with self-reported CO and smoke alarm use of parents recruited from a pediatric emergency department to improve CO alarm use. Parents of children ≤ 18 years (N = 299) reported socio-demographic characteristics and CO and smoke alarm ownership and practices. We assigned participants to a behavioral profile and a Precaution Adoption Process Model stage based on their self-reported CO and smoke alarm use. Most participants (71%) did not have CO alarms in their homes, but reported owning at least one working smoke alarm (98%). Participants who reported "perfect" CO alarm behavior (defined as having a working CO alarm, one near a sleeping area, with batteries replaced every 6 months; 9%) were more likely to earn a higher income, own their home, and have lived at their current residence for at least 2 years. Participants who reported "perfect" smoke alarm behavior (defined as having a working smoke alarm on every level, with batteries replaced every 6 months; 49%) were more likely to rent their home, receive federal assistance, and have lived at their current residence for at least 2 years. Interventions to increase correct CO alarm use are necessary.

Evaluating a smartphone application to improve child passenger safety and fire safety knowledge and behaviour

BACKGROUND

Although proven measures for reducing injury due to motor vehicle collision and residential fires exist, the number of families properly and consistently using child passenger restraints and smoke alarms remains low. This paper describes the design of the Safety In Seconds (SIS) 2.0 study, which aims to evaluate the impact of a smartphone app on parents' use of child restraints and smoke alarms.

METHODS

SIS is a multisite randomised controlled trial. Participants are parents of children aged 4-7 years who are visiting the Pediatric Emergency Department or Pediatric Trauma Service. Parents are randomised to receive tailored education about child passenger safety or about fire safety via the SIS smartphone app. A baseline and two follow-up surveys at 3 months and 6 months are conducted. Primary outcomes are: (1) having the correct child restraint for the child's age and size; (2) restraining the child in the back seat of the car; (3) buckling the child up for every ride; (4) having the restraint inspected by a child passenger safety technician; (5) having a working smoke alarm on every level of the home; (6) having hard-wired or lithium battery smoke alarms; (7) having and (8) practising a fire escape plan.

DISCUSSION

Finding ways to communicate with parents about child passenger and fire safety continues to be a research priority. This study will contribute to the evidence about how to promote benefits of proper and consistent child restraint and smoke alarm use.

Six-month follow-up of lithium-battery smoke alarms and self-reported reasons for disabling

Although smoke alarms with lithium batteries are often marketed as '10-year alarms', on average, these alarms do not remain functional for 10 years. This paper describes self-reported reasons for non-working lithium-battery alarms 6-9 months following a smoke alarm installation programme. Data presented are for a cohort of 754 homes that participated in the installation programme and subsequently completed follow-up. A total of 1487 smoke alarms were installed. At follow-up, 126 alarms (8%) were missing and 37 (3%) were observed to be non-working. Of the non-working alarms, residents reported that they had been disabled 57% of the time. Reasons for disabling the alarms most often included that the battery was chirping (38%) or that it sounded while someone was cooking (24%). Smoke alarm installation programmes using lithium-battery alarms should consider highlighting education about smoke alarm maintenance, the hush feature and resources to replace alarms that malfunction soon after installation.

Smoke alarm giveaway and installation programs: an economic evaluation

BACKGROUND

The burden of residential fire injury and death is substantial. Targeted smoke alarm giveaway and installation programs are popular interventions used to reduce residential fire mortality and morbidity.

PURPOSE

To evaluate the cost effectiveness and cost benefit of implementing a giveaway or installation program in a small hypothetic community with a high risk of fire death and injury through a decision-analysis model.

METHODS

Model inputs included program costs; program effectiveness (life-years and quality-adjusted life-years saved); and monetized program benefits (medical cost, productivity, property loss and quality-of-life losses averted) and were identified through structured reviews of existing literature (done in 2011) and supplemented by expert opinion. Future costs and effectiveness were discounted at a rate of 3% per year. All costs were expressed in 2011 U.S. dollars.

RESULTS

Cost-effectiveness analysis (CEA) resulted in an average cost-effectiveness ratio (ACER) of $51,404 per quality-adjusted life-years (QALYs) saved and $45,630 per QALY for the giveaway and installation programs, respectively. Cost-benefit analysis (CBA) showed that both programs were associated with a positive net benefit with a benefit-cost ratio of 2.1 and 2.3, respectively. Smoke alarm functional rate, baseline prevalence of functional alarms, and baseline home fire death rate were among the most influential factors for the CEA and CBA results.

CONCLUSIONS

Both giveaway and installation programs have an average cost-effectiveness ratio similar to or lower than the median cost-effectiveness ratio reported for other interventions to reduce fatal injuries in homes. Although more effort is required, installation programs result in lower cost per outcome achieved compared with giveaways.

Igniting interest in prevention: using firefighter focus groups to inform implementation and enhancement of an urban canvassing program

CONTEXT

Smoke alarm canvassing is recognized as an empirically based, effective intervention for increasing access to and the presence of smoke alarms in homes.

OBJECTIVES

We sought to inform the implementation of an intervention designed to enhance an existing fire department smoke alarm canvassing program through an empirically grounded, participatory process.

DESIGN

We conducted a series of focus groups with fire union leaders and firefighters involved with the canvassing program in 1 US city, shared the results with the participants, and presented the resulting recommendations to fire department leadership.

SETTING

This research occurred in Baltimore, Maryland.

PARTICIPANTS

Focus group participants included firefighters who participate in the Fire Department's smoke alarm canvassing program and representatives from the local firefighters' union.

MAIN OUTCOME MEASURES

The focus groups sought to capture firefighters' experiences with and opinions about the canvassing program and how to improve it as well as challenges to canvassing work.

RESULTS

We conducted 10 focus groups with 65 participants. Firefighters' perspectives on the canvassing program and their recommendations for improving it were expressed through 3 categories of themes concerning program management, canvassing challenges, and attitudes about the program and the community. We also discuss the process of presenting these findings and recommendations to the participants and the fire department leadership, and describe how implementation of some of the recommendations has progressed.

CONCLUSIONS

Both the process and outcomes of this formative work inform how to develop and implement community-based public health interventions in real-world settings through academic-community partnerships. The findings also have implications for how canvassing programs are being implemented.

Comprehensive smoke alarm coverage in lower economic status homes: alarm presence, functionality, and placement

The objectives of this study are to estimate smoke alarm coverage and adherence with national guidelines in low- to mid-value owner-occupied residences, and to identify resident demographic, behavioral, and building characteristics and other fire and burn safety practices associated with smoke alarm utilization. Baseline visits were conducted with 779 households in King County, Washington, for a randomized trial of smoke alarm functionality. Presence, functionality, features, and location of pre-existing smoke alarms were ascertained by staff observation and testing. Household and building descriptors were collected using questionnaires. Households were classified by presence of smoke alarms, functional alarms, and functional and properly mounted alarms placed in hallways and on each floor but not in recommended avoidance locations. Smoke alarms were present in 89%, and functional units in 78%, of households. Only 6-38% met all assessed functionality and placement recommendations. Homes frequently lacked alarms in any bedrooms or on each floor. Building age, but not renovation status, was associated with all dimensions of smoke alarm coverage; post-1980 constructions were 1.7 times more likely to comply with placement recommendations than were pre-1941 homes (95% CI: 1.1-2.6). Respondent education and race/ethnicity, children <5 years, residency duration, number of floors, wood stoves and fireplaces, number of smoke alarms, recency of smoke alarm testing, carbon monoxide monitors, and fire ladders displayed varying relationships with alarm presence, functionality, and placement. Strategies for maintaining smoke alarms in functional condition and improving compliance with placement recommendations are necessary to achieve universal coverage, and will benefit the majority of households.

Smoke alarm tests may not adequately indicate smoke alarm function

Smoke alarms are one of the most promoted prevention strategies to reduce residential fire deaths, and they can reduce residential fire deaths by half. Smoke alarm function can be measured by two tests: the smoke alarm button test and the chemical smoke test. Using results from a randomized trial of smoke alarms, we compared smoke alarm response to the button test and the smoke test. The smoke alarms found in the study homes at baseline were tested, as well as study alarms placed into homes as part of the randomized trial. Study alarms were tested at 12 and 42 months postinstallation. The proportion of alarms that passed the button test but not the smoke test ranged from 0.5 to 5.8% of alarms; this result was found most frequently among ionization alarms with zinc or alkaline batteries. These alarms would indicate to the owner (through the button test) that the smoke alarm was working, but the alarm would not actually respond in the case of a fire (as demonstrated by failing the smoke test). The proportion of alarms that passed the smoke test but not the button test ranged from 1.0 to 3.0%. These alarms would appear nonfunctional to the owner (because the button test failed), even though the alarm would operate in response to a fire (as demonstrated by passing the smoke test). The general public is not aware of the potential for inaccuracy in smoke alarm tests, and burn professionals can advocate for enhanced testing methods. The optimal test to determine smoke alarm function is the chemical smoke test.

Safety practices in relation to home ownership among urban Mexican immigrant families

We examined home safety hazards, comparing renter- to owner-occupied housing among urban, immigrant Mexican families.

METHODS

Interviews and home inspections were conducted among urban, Spanish-speaking immigrant families with children. We estimated weighted hazard prevalence and used logistic regression to compare owner- and renter-occupied homes. Of 313 eligible households, 250 (80%) enrolled. Respondents were predominantly Mexican-born (99%), low income (72.6%) and lower education (92.3%). Most homes had fire, burn, fall, poisoning, electrocution and fire escape hazards, including high tap water temperatures (76.4%; 95% CI: 69.0, 83.7%), no working smoke alarms (60.0%; 51.3, 68.8%), slippery bathtub/shower surfaces (58.7%; 49.9, 67.5%), blocked fire escape routes (55.9%; 47.2, 64.5%) and child-accessible medications (71.0%; 60.1, 81.3%). After adjustment for sociodemographics, fire escape (OR = 8.8; 95% CI: 2.8, 27.7), carbon monoxide poisoning (OR = 2.9; 1.4, 6.2) and drowning (OR = 3.5; 1.3, 9.4) hazards were more likely in owner- than renter-occupied homes. Housing age and type explained most differences. Many urban, immigrant Spanish-speaking families live in unsafe homes. For this population, housing safety programs should be targeted based on housing age and type rather than tenure.

Smoke alarms by type and battery life in rural households: a randomized controlled trial

BACKGROUND

Although the use of smoke alarms is widely recommended, little guidance is available on the types of alarms and batteries that function best. This study examined smoke alarm and battery function 12 months after installation in rural residential households.

METHODS

An RCT, involving the installation of either a photoelectric or ionizing smoke alarm with either a lithium or carbon-zinc battery, was conducted in 643 rural Iowa households in July 2003. The functionality of each installed smoke alarm was tested 12 months later. Generalized estimating equations were used to model the effects of alarm type and battery type on alarm function and false alarms 12 months after installation.

RESULTS

Of 643 study homes, 98.8% had at least one functioning alarm, and 81.5% had all alarms functioning 12 months after installation. No difference was observed in alarm function between photoelectric alarms and ionizing alarms 12 months after installation (OR=1.30, 95% CI=0.88, 1.92). However, photoelectric alarms had significantly lower odds of false alarms than ionizing alarms. Alarms with lithium batteries had 91% higher odds of functioning than those with carbon-zinc batteries. The main reasons for nonfunctioning included a missing battery (30.7%); a missing alarm (28%); and a disconnected battery (11.3%).

CONCLUSIONS

Although lithium batteries and photoelectric alarms are more expensive than their counterparts, the financial investment might be worthwhile in terms of overall performance.

Risk Factors for Rural Residential Fires

CONTEXT AND PURPOSE

Rural households report high fire-related mortality and injury rates, but few studies have examined the risk factors for fires. This study aims to identify occupant and household characteristics that are associated with residential fires in a rural cohort.

METHODS

Of 1,005 households contacted in a single rural county, 691 (68.8%) agreed to participate. One household with missing information on a reported fire was excluded from the analysis. We used logistic regression to examine the independent association of occupant and household characteristics with reported fires, controlling for years lived in the residence. We also examined the association between the occurrence of previous fires and the adoption of safety measures.

FINDINGS

A total of 78 (11.3%) households reported a residential fire. Occupant characteristics that were associated with significantly higher odds of reported fires included the presence of an occupant with alcohol problems (OR = 1.82, 95% CI = 1.01-3.28) and being married (OR = 2.11, 95% CI = 1.14-3.91). Rural farm households were associated with significantly higher odds (OR = 1.72, 95% CI = 1.01-2.93) of reporting a fire when compared to residences in towns, after controlling for all other occupant and household characteristics. The presence of a fire extinguisher (OR = 2.00, 95% CI = 1.10-3.64) was the only fire safety measure that had a statistically significant association with reported fire.

CONCLUSIONS

Rural farm households report higher incidences of fire when compared to households located in towns. Experiencing a fire is not associated with an increased likelihood of adopting safety measures to prevent injuries once a fire has started.

Interventions for promoting smoke alarm ownership and function

BACKGROUND

Residential fires caused at least 67 deaths and 2,500 non-fatal injuries to children aged 0-16 in the United Kingdom in 1998. Smoke alarm ownership is associated with a reduced risk of residential fire death.

OBJECTIVES

We evaluated interventions to promote residential smoke alarms, to assess their effect on smoke alarm ownership, smoke alarm function, fires and burns and other fire-related injuries.

SEARCH STRATEGY

We searched the Cochrane Controlled Trials Register, Cochrane Injuries Group database, MEDLINE, EMBASE, PsycLIT, CINAHL, ERIC, Dissertation Abstracts, International Bibliography of Social Sciences, ISTP, FIREDOC and LRC. Conference proceedings, published case studies, and bibliographies were systematically searched, and investigators and relevant organisations were contacted, to identify trials.

SELECTION CRITERIA

Randomised, quasi-randomised or nonrandomised controlled trials completed or published after 1969 evaluating an intervention to promote residential smoke alarms.

DATA COLLECTION AND ANALYSIS

Two reviewers independently extracted data and assessed trial quality.

MAIN RESULTS

We identified 26 trials, of which 13 were randomised. Overall, counselling and educational interventions had only a modest effect on the likelihood of owning an alarm (OR=1.26; 95% CI: 0.87 to 1.82) or having a functional alarm (OR=1.19; 0.85 to 1.66). Counselling as part of primary care child health surveillance had greater effects on ownership (OR=1.96; 1.03 to 3.72) and function (OR=1.72; 0.78 to 3.80). Results were sensitive to trial quality, however, and effects on fire-related injuries were not reported. In two non randomised trials, direct provision of free alarms significantly increased functioning alarms and reduced fire-related injuries. Media and community education showed little benefit in non randomised trials.

REVIEWER'S CONCLUSIONS

Counselling as part of child health surveillance may increase smoke alarm ownership and function, but its effects on injuries are unevaluated. Community smoke alarm give-away programmes apparently reduce fire-related injuries, but these trials were not randomised and results must be interpreted cautiously. Further efforts to promote smoke alarms in primary care or through give-away programmes should be evaluated by adequately designed randomised controlled trials measuring injury outcomes.
