Children at risk of medicinal and non-medicinal poisoning: a population-based case-control study in general practice

Characteristics of children aged 5 and under presenting with ingestion: An analysis of cases from a tertiary child protection unit

AIM

This study aimed to determine what proportion of children presenting to a tertiary children's hospital with ingestion were referred for child protection assessment, and to describe the characteristics of the referred group.

METHODS

This is a retrospective case series study of children who presented to a tertiary children's hospital between 1 January 2016 and 31 December 2020 with ingestion (poisoning). Demographic and clinical data were collected from the electronic medical record and patients who underwent child protection assessment were identified. The child protection group was compared to the whole cohort. The child protection group had psychosocial data gathered and descriptively analysed.

RESULTS

Two hundred and three patients were included. The most common substances ingested were over-the-counter medications (45%) followed by prescription medications (41%). Most patients were discharged from the emergency department (70%). Of the 203 patients, 24 (11.8%, 95% CI 7.72-17.08) were referred to the child protection unit. A significant proportion of these patients had a history of parental depression (64%) and other mental health conditions (41%), parent separation (77%) and domestic violence in the home (64%).

CONCLUSION

The patients assessed by the child protection team had high prevalence of psychosocial risk factors that also place the patients at risk of child abuse and neglect. Most of the other patients did not have a psychosocial history documented in the medical record, and this group likely contains a high proportion of vulnerable children. By screening patients presenting with ingestion we may be able to identify children at risk and provide opportunities for protective intervention.

Patterns and trends of medicinal poisoning substances: a population-based cohort study of injuries in 0-11 year old children from 1998-2018

BACKGROUND

There have been sharp increases in antidepressant and opioid prescriptions over the last 10 years, as well as increased over-the-counter medicine availability. However, the impact on childhood medicinal poisonings rates, particularly by socioeconomic deprivation is unclear. This study reports population level medicinal poisoning substance patterns in England among children aged 0-11 years, helping inform safety advice and poisoning prevention interventions.

METHODS

An open cohort study of 1,489,620 0-11 year olds was conducted from 1998 to 2018, using the Clinical Practice Research Datalink, to examine inpatient hospital admissions for poisoning. Incidence rates and adjusted incidence rate ratios (aIRR) were calculated for poisoning substance groups by age, sex, socio-economic deprivation and year.

RESULTS

3,685 medicinal poisoning hospital admissions were identified. The most common substances were paracetamol (33.2%), dependence/withdrawal risk drugs (DWRD - antidepressants, opioids, gabapentinoids, benzodiazepines) (13.5%) and other over-the-counter (OTC) analgesics/anti-common cold drugs (13.0%). Over the study period DWRD poisonings decreased 33% (aIRR 0.67, 95%CI 0.50-0.90 comparing 2013/14-2017/18 to 1998/99-2002/03), while paracetamol poisonings increased 43% (aIRR 1.43, 95%CI 1.20-1.70 for the same periods), with no change in incidence rates for other OTC drugs (aIRR 0.82, 95% CI 0.60-1.12) or all medications combined (aIRR 0.97, 95%CI 0.88-1.07). A gradient in poisonings by area-level socioeconomic deprivation was shown for all medications (aIRR 1.32, 95%CI 1.18-1.47 for most deprived compared to least deprived quintile), and DWRDs (aIRR 2.03, 95%CI 1.42-2.88 for 4th most deprived quintile and aIRR 1.88, 95%CI 1.32-2.66 for 5th most deprived quintile, compared to least deprived quintile), but not for paracetamol or other OTC drug poisonings.

CONCLUSIONS

Poisonings from DWRDs decreased by 33%, while paracetamol poisonings increased by 43% during the study period. There was a gradient by area-level socioeconomic deprivation in prescribed medication poisonings, including drugs with withdrawal/dependence risk, but not OTC medication poisonings. Households in more socioeconomically deprived areas have the potential to benefit most from measures to improve safe storage of medicines and are likely to require targeted interventions providing education and safety equipment. In addition, universal promotion of the safe storage of OTC and prescribed medicines must be provided by prescribers, community pharmacies and other outlets of such medication.

Pediatric poisoning deaths in Saudi Arabia: A systematic review

Poisons are potentially harmful substances that can cause damage to the human body. Children are a vulnerable group to poisoning. This article aims to review the deaths due to poisoning among children in Saudi Arabia. A comprehensive search was conducted on 13 January 2022 using PubMed, Scopus, and Web of Science databases to identify articles that reported on pediatric poisoning deaths in Saudi Arabia. Eight articles met the inclusion criteria and were included in this systematic review. Some articles included one city, for instance, Jeddah or Riyadh, while others included different regions of the country. Children got poisoned most commonly at their homes by accidental ingestion. The common substances that caused fatality included drugs and pesticides. Low caregiver awareness and neglect were recognized as risk factors for pediatric poisoning. Further studies should be conducted to provide comprehensive details about the victims, the poisons involved, and the circumstances of pediatric poisonings in Saudi Arabia at the national and sub-national levels. Public awareness campaigns should be organized to raise community awareness about safety measures and risks of neglect to prevent pediatric poisonings.

The effectiveness of psychosocial interventions at reducing the frequency of alcohol and drug use in parents: findings of a Cochrane Review and meta-analyses

BACKGROUND AND AIM

Parental substance use is a major public health and safeguarding concern. There have been a number of trials examining interventions targeting this risk factor. We aimed to estimate the effectiveness of psychosocial interventions at reducing parental substance use.

DESIGN

We used systematic methods to identify trials; pooling data using a random-effects model. Moderator analyses examined influence of parent gender, presence of child in treatment and intervention type.

SETTING

No restrictions on setting.

PARTICIPANTS

Substance using parents of children below the age of 21 years.

INTERVENTIONS

Psychosocial interventions including those that targeted drug and alcohol use only, and drug and alcohol use in combination with associated issues.

MEASUREMENTS

Frequency of alcohol use and frequency of drug use.

FINDINGS

We included eight unique studies with a total of 703 participants. Psychosocial interventions were more effective at reducing the frequency of parental alcohol use than comparison conditions at 6-month [standardized mean difference (SMD) = - 0.32, 95% confidence interval (CI) = -0.51 to -0.13, P = 0.001] and 12-month follow-up (SMD = -0.25, 95% CI = -0.47 to -0.03, P = 0.02) and frequency of parental drug use at 12 months only (SMD = -0.21, 95% CI = -0.41 to -0.01, P = 0.04). Integrated interventions which combined both parenting and substance use targeted components were effective at reducing the frequency of alcohol use (6 months: SMD = -0.56, 95% CI = -0.96 to -0.016, P = 0.006; 12 months: SMD = -0.42, 95% CI = -0.82 to -0.03, P = 0.04) and drug use (6 months: SMD = -0.39, 95% CI = -0.75 to -0.03, P = 0.04; 12 months: SMD = -0.43, 95% CI = -0.80 to -0.07, P = 0.02). Interventions targeting only substance use or parenting skills were not effective at reducing frequency of alcohol or drug use at either time-point.

CONCLUSION

Psychosocial interventions should target both parenting and substance use in an integrated intervention.

Impact of drug formulation on outcomes of pharmaceutical poisoning in children aged 7 years or younger: A retrospective observational study in South Korea

Pharmaceutical poisoning in children is almost unintentional and there are various types of drug out of curiosity. Understanding the attractive features and formulation of drugs related to poisoning in younger children may be helpful in treatment and prevention of poisoning. To investigate the impact of drug formulation on outcomes of pharmaceutical poisoning in young children.We retrospectively reviewed the data of pharmaceutical exposures among children who were registered in a Korean 23-center, emergency department (ED) based registry from 2011 to 2016. Our study was conducted on preschool children aged 0 to 7 years. According to the formulation and category of the ingested drugs, the exposures were divided into the "tablet and capsule (TAC)" and "syrup" groups. In the TAC group, we additionally recorded data on the shape, color, and size of the drugs. The ED outcomes, such as hospitalization and length of stay, were compared between the 2 groups.Among the 970 enrolled exposures, 674 (69.5%) were classified into the TAC group. In this group, hormones/hormone antagonists (18.5%) were the most commonly ingested, followed by central nervous system drugs (17.1%). In the syrup group, antihistamines (28.4%) were the most commonly ingested, followed by respiratory drugs (24.3%). The TAC group showed a higher hospitalization and transfer rate to tertiary centers than the counterpart (TAC, 18.0% vs syrup, 11.5%, P = .03) without a significant difference in the length of stay (TAC, 173.5 minutes [interquartile range, 95.0-304.0] vs syrup, 152.5 [77.5-272.0]; P = .08). No in-hospital mortality occurred in the exposures. Round-shaped and chromatic TACs, accounting for 91.7% (618) and 56.1% (378), respectively, were more commonly ingested. The median size of the TACs was less than 1.0 cm.Young children who visited the ED ingested TACs more frequently than syrups, particularly small, round-shaped, or chromatic drugs, leading to a higher hospitalization rate. Our findings can contribute to prevention strategies and safety education on childhood drug poisoning.

Effectiveness of psychosocial interventions for reducing parental substance misuse

BACKGROUND

Parental substance use is a substantial public health and safeguarding concern. There have been a number of trials of interventions relating to substance-using parents that have sought to address this risk factor, with potential outcomes for parent and child.

OBJECTIVES

To assess the effectiveness of psychosocial interventions in reducing parental substance use (alcohol and/or illicit drugs, excluding tobacco).

SEARCH METHODS

We searched the following databases from their inception to July 2020: the Cochrane Drugs and Alcohol Group Specialised Register; CENTRAL; MEDLINE; Embase; PsycINFO; CINAHL; Applied Social Science (ASSIA); Sociological Abstracts; Social Science Citation Index (SSCI), Scopus, ClinicalTrials.gov, WHO ICTRP, and TRoPHI. We also searched key journals and the reference lists of included papers and contacted authors publishing in the field.

SELECTION CRITERIA

We included data from trials of complex psychosocial interventions targeting substance use in parents of children under the age of 21 years. Studies were only included if they had a minimum follow-up period of six months from the start of the intervention and compared psychosocial interventions to comparison conditions. The primary outcome of this review was a reduction in the frequency of parental substance use.

DATA COLLECTION AND ANALYSIS

We used standard methodological procedures expected by Cochrane.

MAIN RESULTS

We included 22 unique studies with a total of 2274 participants (mean age of parents ranged from 26.3 to 40.9 years), examining 24 experimental interventions. The majority of studies intervened with mothers only (n = 16; 73%). Heroin, cocaine, and alcohol were the most commonly reported substances used by participants. The interventions targeted either parenting only (n = 13; 59%); drug and alcohol use only (n = 5; 23%); or integrated interventions which addressed both (n = 6; 27%). Half of the studies (n = 11; 50%) compared the experimental intervention to usual treatment. Other comparison groups were minimal intervention, attention controls, and alternative intervention. Eight of the included studies reported data relating to our primary outcome at 6- and/or 12-month follow-up and were included in a meta-analysis. We investigated intervention effectiveness separately for alcohol and drugs. Studies were found to be mostly at low or unclear risk for all 'Risk of bias' domains except blinding of participants and personnel and outcome assessment.  We found moderate-quality evidence that psychosocial interventions are probably more effective at reducing the frequency of parental alcohol misuse than comparison conditions at 6-month (mean difference (MD) -0.32, 95% confidence interval (CI) -0.51 to -0.13; 6 studies, 475 participants) and 12-month follow-up (standardised mean difference (SMD) -0.25, 95% CI -0.47 to -0.03; 4 studies, 366 participants). We found a significant reduction in frequency of use at 12 months only (SMD -0.21, 95% CI -0.41 to -0.01; 6 studies, 514 participants, moderate-quality evidence). We examined the effect of the intervention type. We found low-quality evidence that psychosocial interventions targeting substance use only may not reduce the frequency of alcohol (6 months: SMD -0.35, 95% CI -0.86 to 0.16; 2 studies, 89 participants and 12 months: SMD -0.09, 95% CI -0.86 to 0.61; 1 study, 34 participants) or drug use (6 months: SMD 0.01, 95% CI -0.42 to 0.44; 2 studies; 87 participants and 12 months: SMD -0.08, 95% CI -0.81 to 0.65; 1 study, 32 participants). A parenting intervention only, without an adjunctive substance use component, may not reduce frequency of alcohol misuse (6 months: SMD -0.21, 95% CI -0.46 to 0.04, 3 studies; 273 participants, low-quality evidence and 12 months: SMD -0.11, 95% CI -0.64 to 0.41; 2 studies; 219 participants, very low-quality evidence) or frequency of drug use  (6 months: SMD 0.10, 95% CI -0.11 to 0.30; 4 studies; 407 participants, moderate-quality evidence and 12 months: SMD -0.13, 95% CI -0.52 to 0.26; 3 studies; 351 participants, very low-quality evidence). Parents receiving integrated interventions which combined both parenting- and substance use-targeted components may reduce alcohol misuse with a small effect size (6 months: SMD -0.56, 95% CI -0.96 to -0.16 and 12 months: SMD -0.42, 95% CI -0.82 to -0.03; 2 studies, 113 participants) and drug use (6 months: SMD -0.39, 95% CI -0.75 to -0.03 and 12 months: SMD -0.43, 95% CI -0.80 to -0.07; 2 studies, 131 participants). However, this evidence was of low quality. Psychosocial interventions in which the child was present in the sessions were not effective in reducing the frequency of parental alcohol or drug use, whilst interventions that did not involve children in any of the sessions were found to reduce frequency of alcohol misuse (6 months: SMD -0.47, 95% CI -0.76 to -0.18; 3 studies, 202 participants and 12 months: SMD -0.34, 95% CI -0.69 to 0.00; 2 studies, 147 participants) and drug use at 12-month follow-up (SMD -0.34, 95% CI -0.69 to 0.01; 2 studies, 141 participants). The quality of this evidence was low. Interventions appeared to be more often beneficial for fathers than for mothers. We found low- to very low-quality evidence of a reduction in frequency of alcohol misuse for mothers at six months only (SMD -0.27, 95% CI -0.50 to -0.04; 4 studies, 328 participants), whilst in fathers there was a reduction in frequency of alcohol misuse (6 months: SMD -0.43, 95% CI -0.78 to -0.09; 2 studies, 147 participants and 12 months: SMD -0.34, 95% CI -0.69 to 0.00; 2 studies, 147 participants) and drug use (6 months: SMD -0.31, 95% CI -0.66 to 0.04; 2 studies, 141 participants and 12 months: SMD -0.34, 95% CI -0.69 to 0.01; 2 studies, 141 participants).

AUTHORS' CONCLUSIONS

We found moderate-quality evidence that psychosocial interventions probably reduce the frequency at which parents use alcohol and drugs. Integrated psychosocial interventions which combine parenting skills interventions with a substance use component may show the most promise. Whilst it appears that mothers may benefit less than fathers from intervention, caution is advised in the interpretation of this evidence, as the interventions provided to mothers alone typically did not address their substance use and other related needs. We found low-quality evidence from few studies that interventions involving children are not beneficial.

Evaluation of the effectiveness, implementation and cost-effectiveness of the Stay One Step Ahead home safety promotion intervention for pre-school children: a study protocol

BACKGROUND

Unintentional injuries in children under the age of 5 years commonly occur in the home and disproportionately affect those living in disadvantaged circumstances. Targeted home safety promotion should be offered to families most at risk but there is a paucity of standardised evidence-based resources available for use across family-support practitioners.

OBJECTIVE

To assess the effectiveness, implementation and cost-effectiveness of a 2-year home safety programme (Stay One Step Ahead) developed by parents, practitioners and researchers, and delivered by a range of family support providers in inner-city localities, compared with usual care in matched control localities.

METHODS

Parents of children aged 0 to 7 months will be recruited to a controlled before and after observational study. The primary outcome is home safety assessed by the proportion of families with a fitted and working smoke alarm, safety gate on stairs (where applicable) and poisons stored out of reach, assessed using parent-administered questionnaires at baseline, 12 and 24 months.Secondary outcomes include: the impact on other parent-reported safety behaviours, medically-attended injuries, self-efficacy for home safety and knowledge of child development and injury risk using questionnaires and emergency department attendance data; implementation (reach, acceptability, barriers, facilitators) of home safety promotion assessed through interviews and observations; and cost-effectiveness using medically-attended injury costs ascertained from healthcare records.

CONCLUSION

If shown to be effective and cost-effective this study will provide a practical resource to underpin national guidance. The study could inform public health prevention strategies to reduce home injury in children most at risk, while delivering cost savings to health and care services.

The Association Between Adverse Child Health, Psychological, Educational and Social Outcomes, and Nondependent Parental Substance: A Rapid Evidence Assessment

BACKGROUND

Between 5% and 30% of children in high-income countries live with a substance misusing parent, the majority of which is below dependent levels. However, little is understood about the impact of nondependent parental substance misuse upon children.

METHODS

We searched the international literature using rigorous systematic methods to identify studies examining parental substance misuse and adverse outcomes in children. The inclusion criteria were cross-sectional, longitudinal, case-control, and cohort studies; of children aged 0-18 years whose parents are high-risk substance misusers; reporting on their health, psychological, substance use, educational, and social outcomes.

RESULTS

We identified 36 papers (from 33 unique studies), most of which were assessed as being of medium to high methodological quality (N= 28). Parental nondependent substance misuse was found to be associated with adversity in children, with strong evidence of an association with externalizing difficulties (N = 7 papers, all finding an association) and substance use (N = 23 papers, all finding an association) in adolescents and some evidence of adverse health outcomes in early childhood (N = 6/8 papers finding an association). There is less evidence of an association between parental substance misuse and adverse educational and social outcomes. The body of evidence was largest for parental alcohol misuse, with research examining the impact of parental illicit drug use being limited.

CONCLUSION

Methodological limitations restrict our ability to make causal inference. Nonetheless, the prevalence of adverse outcomes in children whose parents are nondependent substance misusers highlights the need for practitioners to intervene with this population before a parent has developed substance dependency.

Demographic and clinical characteristics of hospitalised unintentional poisoning in Aboriginal and non-Aboriginal preschool children in New South Wales, Australia: a population data linkage study

OBJECTIVES

To investigate differences in demographic and clinical characteristics of Aboriginal and non-Aboriginal children aged 0-4 years hospitalised for unintentional poisoning in New South Wales (NSW), Australia.

DESIGN AND SETTING

Retrospective whole-of-population cohort analysis of linked hospital and mortality data for 2000-2014.

PARTICIPANTS

All children (Aboriginal and non-Aboriginal) under the age of 5 years who were born in a hospital in NSW from 2000 to 2009.

OUTCOMES

The primary outcome was hospitalisation for unintentional poisoning. Logistic regression was used to estimate odds of poisoning hospitalisation for Aboriginal and non-Aboriginal children. Poisoning agents and clinical outcomes were compared by Aboriginality.

RESULTS

The cohort included 767 119 children, including 28 528 (3.7%) Aboriginal children. Aboriginal children had approximately three times higher rates of hospitalised poisoning (1.34%) compared with non-Aboriginal children (0.41%). Poisoning incidence peaked at 2-3 years of age. Male sex, socioeconomic disadvantage and geographical remoteness were associated with higher odds of poisoning hospitalisation for Aboriginal and non-Aboriginal children, but associations with disadvantage and remoteness were statistically significant only for non-Aboriginal children. Most (83%) poisonings were caused by pharmaceutical agents. Few Aboriginal and non-Aboriginal children had repeat admissions for poisoning; most had a length of stay of 1 day or less. Only 8% of poisoning admissions involved contact with a social worker.

CONCLUSION

Commonly used medications in the general population contribute to poisonings among both Aboriginal and non-Aboriginal preschool-aged children. This study highlights a need to develop culturally safe poisoning prevention strategies and policies.

Patterns and outcome of acute poisoning among children in rural Sri Lanka

Background

The burden of poisoning among children is largely underexplored in rural Sri Lanka. This study describes the patterns of demographic characteristics, poison related factors, clinical management and outcome following acute poisoning among children (9 months- 12 years) in rural Sri Lanka.

Method

This hospital based multi-center study included Anuradhapura Teaching hospital, Polonnaruwa District General hospital, and 34 regional hospitals within Regional Director of Health Services in North Central province of Sri Lanka. The study assessed clinical profiles, poison related factors, clinical management, complications, harmful first aid practices, reasons for delayed management, complications and outcomes following acute poisoning over 7 years.

Results

Among 1621 children with acute poisoning, the majority were in preschool age group. Household chemicals were accountable for 489 acute poisonings (30.2%). The most common poison was kerosene oil, followed by paracetamol. Most events occurred within their own domestic premises. Potentially harmful first aid measures were practiced by approximately one third of care givers. Reasons for delayed presentation at emergency center included lack of concern by family members regarding the urgency of the situation and lack of knowledge regarding possible complications. Complications were observed in 12.5% and the most common complication was chemical pneumonitis.

Conclusions

Children with acute poisoing in rural Sri Lanka were predominantly preschoolers. They are poisonined mostly within their own housing premises. Kerosene oil, in addition to being the most common poison, had additional risks of aspiration pneumonia following potentially hazadrous first aid measures practised by the care givers. Complications though rare were potentially preventable by community education and awareness on timely attention to seek medical care, and avoidance of harmful first aid practices.

Promoting Alcohol Reduction in Non-Treatment Seeking parents (PAReNTS): a protocol for a pilot feasibility cluster randomised controlled trial of alcohol screening and brief interventions to reduce parental alcohol use disorders in vulnerable families

Background

Research estimates that 30% of children under the age of 16 years in the UK live with at least one parent with an alcohol use disorder (AUD). Parental AUDs are associated with adverse childhood experiences and poorer outcomes for children. The PAReNTS (Promoting Alcohol Reduction in Non-Treatment Seeking parents) trial aims to examine the feasibility and acceptability of a randomised controlled trial of brief alcohol interventions to reduce parental alcohol misuse.

Methods

The cluster randomised controlled trial will be conducted within early help family support and children’s social care services in three local authorities in the North East of England: Newcastle, Durham and North Tyneside. All eligible parents the caseloads of participating practitioners will be screened for an AUD using the Alcohol Use Disorder Identification Test – Consumption (AUDIT-C) screening tool by the social care practitioners within routine appointments. All parents who score 5 or more on the AUDIT-C will be invited to participate in the trial. Consenting participants will complete a baseline questionnaire before receiving one of three randomised interventions: (i) healthy lifestyle leaflet (control intervention); (ii) a brief alcohol advice intervention delivered by the social care practitioner plus healthy lifestyle leaflet; (iii) a brief alcohol advice intervention delivered by the social care practitioner, healthy lifestyle leaflet plus a 40-min behaviour change intervention with an optional review session delivered by the local alcohol service. Follow-up data will be collected 6 and 12 months post recruitment. A linked qualitative study will explore participating parent and practitioner views on the acceptability of trial processes and interventions.

Discussion

The PAReNTS trial will provide a robust estimate of recruitment, retention and consent rates in order to inform the design of a future definitive study examining the effectiveness and cost-effectiveness of alcohol screening and brief interventions to reduce parental AUDs within vulnerable families.

Keeping Children Safe: a multicentre programme of research to increase the evidence base for preventing unintentional injuries in the home in the under-fives

Background

Unintentional injuries among 0- to 4-year-olds are a major public health problem incurring substantial NHS, individual and societal costs. However, evidence on the effectiveness and cost-effectiveness of preventative interventions is lacking.

Aim

To increase the evidence base for thermal injury, falls and poisoning prevention for the under-fives.

Methods

Six work streams comprising five multicentre case–control studies assessing risk and protective factors, a study measuring quality of life and injury costs, national surveys of children’s centres, interviews with children’s centre staff and parents, a systematic review of barriers to, and facilitators of, prevention and systematic overviews, meta-analyses and decision analyses of home safety interventions. Evidence from these studies informed the design of an injury prevention briefing (IPB) for children’s centres for preventing fire-related injuries and implementation support (training and facilitation). This was evaluated by a three-arm cluster randomised controlled trial comparing IPB and support (IPB+), IPB only (no support) and usual care. The primary outcome was parent-reported possession of a fire escape plan. Evidence from all work streams subsequently informed the design of an IPB for preventing thermal injuries, falls and poisoning.

Results

Modifiable risk factors for falls, poisoning and scalds were found. Most injured children and their families incurred small to moderate health-care and non-health-care costs, with a few incurring more substantial costs. Meta-analyses and decision analyses found that home safety interventions increased the use of smoke alarms and stair gates, promoted safe hot tap water temperatures, fire escape planning and storage of medicines and household products, and reduced baby walker use. Generally, more intensive interventions were the most effective, but these were not always the most cost-effective interventions. Children’s centre and parental barriers to, and facilitators of, injury prevention were identified. Children’s centres were interested in preventing injuries, and believed that they could prevent them, but few had an evidence-based strategic approach and they needed support to develop this. The IPB was implemented by children’s centres in both intervention arms, with greater implementation in the IPB+ arm. Compared with usual care, more IPB+ arm families received advice on key safety messages, and more families in each intervention arm attended fire safety sessions. The intervention did not increase the prevalence of fire escape plans [adjusted odds ratio (AOR) IPB only vs. usual care 0.93, 95% confidence interval (CI) 0.58 to 1.49; AOR IPB+ vs. usual care 1.41, 95% CI 0.91 to 2.20] but did increase the proportion of families reporting more fire escape behaviours (AOR IPB only vs. usual care 2.56, 95% CI 1.38 to 4.76; AOR IPB+ vs. usual care 1.78, 95% CI 1.01 to 3.15). IPB-only families were less likely to report match play by children (AOR 0.27, 95% CI 0.08 to 0.94) and reported more bedtime fire safety routines (AOR for a 1-unit increase in the number of routines 1.59, 95% CI 1.09 to 2.31) than usual-care families. The IPB-only intervention was less costly and marginally more effective than usual care. The IPB+ intervention was more costly and marginally more effective than usual care.

Limitations

Our case–control studies demonstrate associations between modifiable risk factors and injuries but not causality. Some injury cost estimates are imprecise because of small numbers. Systematic reviews and meta-analyses were limited by the quality of the included studies, the small numbers of studies reporting outcomes and significant heterogeneity, partly explained by differences in interventions. Network meta-analysis (NMA) categorised interventions more finely, but some variation remained. Decision analyses are likely to underestimate cost-effectiveness for a number of reasons. IPB implementation varied between children’s centres. Greater implementation may have resulted in changes in more fire safety behaviours.

Conclusions

Our studies provide new evidence about the effectiveness of, as well as economic evaluation of, home safety interventions. Evidence-based resources for preventing thermal injuries, falls and scalds were developed. Providing such resources to children’s centres increases their injury prevention activity and some parental safety behaviours.

Future work

Further randomised controlled trials, meta-analyses and NMAs are needed to evaluate the effectiveness and cost-effectiveness of home safety interventions. Further work is required to measure NHS, family and societal costs and utility decrements for childhood home injuries and to evaluate complex multicomponent interventions such as home safety schemes using a single analytical model.

A decision analytic model to investigate the cost-effectiveness of poisoning prevention practices in households with young children

BACKGROUND

Systematic reviews and a network meta-analysis show home safety education with or without the provision of safety equipment is effective in promoting poison prevention behaviours in households with children. This paper compares the cost-effectiveness of home safety interventions to promote poison prevention practices.

METHODS

A probabilistic decision-analytic model simulates healthcare costs and benefits for a hypothetical cohort of under 5 year olds. The model compares the cost-effectiveness of home safety education, home safety inspections, provision of free or low cost safety equipment and fitting of equipment. Analyses are conducted from a UK National Health Service and Personal Social Services perspective and expressed in 2012 prices.

RESULTS

Education without safety inspection, provision or fitting of equipment was the most cost-effective strategy for promoting safe storage of medicines with an incremental cost-effectiveness ratio of £2888 (95 % credible interval (CrI) £1990-£5774) per poison case avoided or £41,330 (95%CrI £20,007-£91,534) per QALY gained compared with usual care. Compared to usual care, home safety interventions were not cost-effective in promoting safe storage of other household products.

CONCLUSION

Education offers better value for money than more intensive but expensive strategies for preventing medicinal poisonings, but is only likely to be cost-effective at £30,000 per QALY gained for families in disadvantaged areas and for those with more than one child. There was considerable uncertainty in cost-effectiveness estimates due to paucity of evidence on model parameters. Policy makers should consider both costs and effectiveness of competing interventions to ensure efficient use of resources.

Risk factors for long-bone fractures in children up to 5 years of age: a nested case-control study

AIM

To investigate risk factors for first long-bone fractures in children up to 5 years old in order to provide evidence about which families could benefit from injury prevention interventions.

METHODS

Population-based matched nested case-control study using The Health Improvement Network, a UK primary care research database, 1988-2004. Maternal, household and child risk factors for injury were assessed among 2456 children with long-bone fractures (cases). 23,661 controls were matched to cases on general practice. Adjusted ORs and 95% CIs were estimated using conditional logistic regression.

RESULTS

Fractures of long-bones were independently associated with younger maternal age and higher birth order, with children who were the fourth-born in the family, or later, having a threefold greater odds of fracture compared to first-born children (adjusted OR 3.12, 95% CI 2.08 to 4.68). Children over the age of 1 year had a fourfold (13-24 months, adjusted OR 4.09 95% CI 3.51 to 4.76) to fivefold (37+ months, adjusted OR 4.88 95% CI 4.21 to 5.66) increase in the odds of a long-bone fracture compared to children aged 0-12 months. Children in families with a history of maternal alcohol misuse had a raised odds of long-bone fracture (adjusted OR 2.33, 95% CI 1.13 to 4.82) compared to those with no documented history.

CONCLUSIONS

Risk factors for long-bone fractures in children less than 5 years old included age above 1 year, increasing birth order, younger maternal age and maternal alcohol misuse. These risk factors should be used to prioritise families and communities for injury prevention interventions.
