Single-Use Laundry Detergent Pack Exposures in Children Under 6 Years: A Prospective Study at U.S. Poison Control Centers.

BACKGROUND: After the widespread introduction of single-use liquid laundry detergent packs (LLDPs), a prospective observational study was initiated among 12 U.S. poison control centers (PCCs), serving 25% of the population. OBJECTIVES: To evaluate qualitative and quantitative data, including demographics, route of exposure, clinical effects, medical outcome, management site, level of care, and circumstantial variables surrounding the LLDP exposure. METHODS: Analysis of LLDP exposures involving children (age < 6 years) reported to PCCs participating in the prospective study (March 2012-February 2016). PCCs captured a detailed exposure history and followed each patient to symptom resolution. Each case narrative was reviewed to isolate key patient, product, and situational variables and to verify accuracy of coded data. Trend and comparative analyses were performed on absolute case counts, relative proportions, and reporting rates normalized using Nielsen consumption data. Separately, the impact of exposure reduction interventions introduced by a single manufacturer were assessed by comparing reporting rate during pre-/postintervention periods. RESULTS: There were 11,175 childhood exposures reported, with 90.3% involving children aged ≤ 3 years. Ingestion (82.6%) and ocular (14.2%) were the major routes of exposure. The size of the market for LLDPs more than doubled from ∼2.0 to ∼4.6 million LLDPs purchased. Total exposure reports increased from Year 1 (n = 2297) to Year 4 (n = 3206), however, normalized reporting rates dropped by 37% (4.4 to 2.8 exp/million LLDPs purchased). Significant declines (p < 0.0001) were also observed for ingestions and ocular exposures with major/moderate outcome. CONCLUSIONS: There was a significant reduction in exposures that resulted in major/moderate outcomes, and the majority of patients did not require intervention in an emergency department setting.

Pick your poison: what's new in poison control for the preschooler.

Accidental childhood poisonings are a major public health concern despite many efforts to alleviate this problem. While the rate of pediatric fatalities due to poisonings have decreased over the last two decades, poison control centers around the US have collectively fielded over one million calls with regard to toxic exposures in the preschool age group. According to the American Association of Poison Control Centers nearly half of all human exposures reported last year involved children under six. By focusing poison prevention efforts on the preschooler, we can attempt to decrease morbidity and mortality in the most vulnerable age group affected. Although the subject is still prevalent, current discussion on this topic is limited. Newer literature discusses past initiatives such as child resistant packaging and sticker deterrent programs and addresses their efficacy. This article revisits older mechanisms of prevention as well as the science behind the human motivation to change one's own practice and behavior.

Why are adults exposed to liquid laundry detergent capsules?

INTRODUCTION: Exposures to liquid laundry detergent capsules in adults are less well characterized than in children. METHODS: All enquiries to the Centro Antiveleni di Milano regarding adults (>18 years) who were exposed to these capsules between July 2010 and July 2023 were analyzed. Enquiries were followed up with one or more recalls depending on the severity of the patient. RESULTS: Over the study period, 127 adults were exposed. The age distribution was as follows: 34 patients were aged 18-39 years, 29 were 40-59 years, 24 were 60-79 years, 26 were 80-96 years, and the age was unknown in 14. Exposure occurred mainly as a result of ingestion alone (n = 54), skin contact alone (n = 23), and eye contact alone (n = 31). Oral exposure without swallowing occurred in nine cases, and inhalation of the odour from a disintegrated capsule in four. Multiple routes of exposure were involved in six patients. Thirty-four (63 per cent) of the 54 ingestions occurred in those with dementia or intellectual disability, and three patients in this group died. Dermal or eye exposures did not involve those with dementia. CONCLUSIONS: These data show that the majority of adults in Italy who ingest liquid laundry detergent capsules are suffering from dementia or other cognitive impairment.

Seniors and single-use detergent sacs (SUDS): a review of the National Poison Data System from 2012 to 2020.

INTRODUCTION: Exposure to single-use detergent sacs (SUDS), or laundry pods, have declined in the pediatric population between 2015 and 2018. Older adult exposures are less well described, and it is unclear if there is an increased risk of unintentional exposure to SUDS in older adults, especially in those with dementia. This study aims to review SUDS exposures in adults greater than 60-year-old between 2012 and 2020. METHODS: Using the National Poison Data System (NPDS), a query was performed for cases involving an acute single substance exposure with substance coded as "laundry detergent unit dose" (Generic code: 0201181, 0201182, and 0201183) in adults greater than 60-years-old between January 1, 2012 and December 31, 2020. Exclusion criteria included unknown age, age less than 60 years, any multi-substance exposure, and chronic or acute-on-chronic acuity. The distribution of cases was analyzed for demographics, exposure circumstances, management, clinical effects, and medical outcome. RESULTS: SUDS exposure reported to NPDS increased from 46 cases in 2012 to 219 cases in 2020. Among the 1289 total reported cases, 94.9% (n = 1223) were unintentional exposures with an average age of 75-year-old. The majority of exposures occurred in females (69%, n = 883). More than 1 exposure route was reported in 90 cases (7%), and the most common route of exposure was ingestion (64.9%, n = 836). Major effects were identified in 1% (n = 13) of exposures, and 0.5% (n = 7) of cases resulted in death. CONCLUSIONS: Despite a declining incidence of pediatric SUDS exposure, older adult exposures have increased over 400% between 2012 and 2020.

A review of 4652 exposures to liquid laundry detergent capsules reported to the United Kingdom National Poisons Information Service 2008-2018.

Introduction: Liquid laundry detergent capsules contain concentrated liquid laundry detergent in a water-soluble polyvinyl alcohol membrane.Objective: To review 4652 exposures reported to the United Kingdom National Poisons Information Service (NPIS) and to assess the impact of regulatory changes on potential toxicity.Methods: Telephone enquiries to the NPIS and returned questionnaires for these products were analyzed for the period January 2008 to December 2018.Results: Data on 4652 exposures were reported by telephone or questionnaire, of which 95.4% involved children aged ≤5 years. Overall, 1738 of 4594 patients remained asymptomatic (Poisoning Severity Score [PSS] 0), 2729 developed minor (PSS 1) features, 107 suffered moderate features (PSS 2), 19 were graded as severe (PSS 3) and one died. Ingestion was involved in most exposures (n = 4175): vomiting occurred in 46.5%, coughing occurred in 4.3% and central nervous system depression in 3.2%. Nine (0.2%) children were intubated and ventilated. The eye was exposed in 646 cases: 371 (59.8%) suffered conjunctivitis or eye irritation and 21 (3.4%) had keratitis/corneal damage, which persisted in one patient for 9 d. The skin was involved in 364 cases; in 127 (35.5%) minor dermal features developed including erythema, irritation and rash. The most commonly reported features in the 127 cases with PSS ≥2 were vomiting (n = 75), stridor (n = 34), CNS depression (n = 22), keratitis/corneal damage (n = 21), coughing (n = 18), conjunctivitis (n = 13), hypersalivation (n = 12), foaming from the mouth (n = 11) and hypoxemia (n = 11). However, respiratory features (stridor, hypoxemia, bronchospasm, respiratory distress, dyspnea, pulmonary aspiration and tachypnea) were the reason for grading 56 of 127 cases as PSS ≥2.Conclusions: This large data set of 4652 exposures is reassuring in that 97.2% of exposures resulted in no or only minor features, only 107 patients suffered moderate features (PSS 2) and 19 severe (PSS 3) features; one patient died.

Liquid laundry detergent capsules (PODS): a review of their composition and mechanisms of toxicity, and of the circumstances, routes, features, and management of exposure.

Introduction: Liquid laundry detergent capsules (also called single-use detergent sacs; laundry pods; laundry packets) have become an increasingly popular household product worldwide. Objectives: To review the composition and mechanisms of toxicity of liquid laundry detergent, capsules, and the circumstances, routes, clinical features (and impact of packaging changes) and management of exposure. Methods: The databases PubMed and EMBASE were searched using the terms: "detergent" and "capsule", "pod", "pac" or "sac" combined with "poison", "ingest", "expos" but not "animal" or "in vitro" or "bacteria". The searches yielded 289 articles, of which 186 were excluded: 38 duplicates, 133 not relevant, 10 abstracts which had been published as a paper and 5 non-English language articles. The bibliographies of relevant articles were hand-searched which yielded 14 additional citations. Searching of abstracts from scientific meetings produced five additional citations. A total of 122 publications were relevant to the objectives of the review. Capsules and composition: Capsules typically contain anionic surfactants (20-35%), non-ionic surfactants (10-20%), propylene glycol (8-20%) and ethanol (2-5%) within a water-soluble polyvinyl alcohol membrane. Mechanisms of toxicity: Non-ionic surfactants are the primary mechanism, though anionic surfactants, ethanol and propylene glycol may also contribute. Circumstances of exposure: The majority (60%) of children are exposed when the capsule is removed from its original container. Routes of exposure: Ingestion is the most common (>85%); ocular (<15%) and dermal (<8%) exposure account for the remainder. Features following ingestion: Features develop in around half of all exposures, though >90% are minor. In those with features, vomiting occurs in some 50%; coughing and drowsiness are reported in <5%. Respiratory depression (<0.5%), central nervous system depression (<0.1%) esophageal or gastric injury (<0.5%), metabolic acidosis and hyperlactatemia (<0.05%) have been reported rarely. Of 17 deaths reported, 13 were adults and nine were suffering from cognitive impairment. Features following ocular exposure: Conjunctivitis, eye irritation and/or eye pain are commonly experienced; corneal injury is less common but complete recovery typically occurs within one week. Features following dermal exposure: Clinically important dermal toxicity seldom occurs, though skin burns can develop in <5% of cases when skin contact is prolonged. Impact of packaging changes on features: The implementation of packaging changes resulted in a fall in the number of exposures and their severity in the United States and in the number in Italy. Management-ingestion: Gut decontamination is not recommended, though small amounts of fluid can be administered orally to rinse out the mouth. Symptomatic and supportive care should be offered to all patients that develop features of toxicity. Supplemental oxygen should be administered for hypoxemia, and bronchodilators for laryngospasm/bronchospasm. Intubation and assisted ventilation may be required if CNS and respiratory depression develop. A chest radiograph should be performed if respiratory features develop. In patients with swallowing difficulties, drooling or oropharyngeal burns, endoscopy should be performed; if substantial mucosal damage is present MRI should be considered. In addition, intravenous fluids will be required if prolonged vomiting or diarrhea occur and acid-base disturbances should be corrected. Management-eye exposure: Thorough irrigation of the eye with sodium chloride 0.9% is required. Instillation of a local anesthetic will reduce discomfort and help more thorough decontamination. Due to the potential for corneal injury, fluorescein should be instilled. If ocular injury is present, the patient should be referred to an ophthalmologist. Management-skin exposure: Skin should be irrigated thoroughly with soap and water, and burns should be treated as a thermal burn. Conclusions: Accidental ingestion usually produces no or only minor features. Very rarely respiratory depression, central nervous system depression, esophageal or gastric injury, hyperlactatemia and metabolic acidosis occur. Ocular exposure results in corneal injury infrequently and skin burns can develop uncommonly following prolonged dermal contact. Of 17 deaths reported, 13 were adults and nine were suffering from cognitive impairment.

The impact of an international initiative on exposures to liquid laundry detergent capsules reported to the United Kingdom National Poisons Information Service between 2008 and 2015.

INTRODUCTION: Although the majority of those exposed to liquid laundry detergent capsules remain asymptomatic or suffer only minor clinical features after exposure, a small proportion develop central nervous system depression, stridor, pulmonary aspiration and/or airway burns following ingestion or conjunctivitis and corneal ulceration following eye exposure. As a consequence, the International Association for Soaps, Detergents and Maintenance Products (AISE) established a Product Stewardship Programme in Europe, requiring that safety measures be implemented to reduce the visibility of, and restrict access to, these detergent capsules by small children. Implementation occurred in the United Kingdom over several months during the first half of 2013. OBJECTIVE: This study investigated whether the AISE Programme had an impact on the number and severity of exposures reported to the United Kingdom National Poisons Information Service. METHODS: Telephone enquiries to the National Poisons Information Service relating to liquid laundry detergent capsules were analysed for the period January 2008 to December 2015. RESULTS: While there was a significant difference (p = 0.0002) between the mean number of annual exposures (469.4) reported between 2008 and 2012 and the mean number reported between 2014 and 2015 (403.5), the number of exposures was decreasing steadily prior to implementation of the Programme in 2013, which did not impact this fall from 2013 onwards. In addition, the number of exposures per million units sold was not impacted by the Programme. There was no significant difference (p = 0.68) between the mean number of exposures (11.8) with PSS ≥2 reported between 2008 and 2012 and the mean number (13.0) reported between 2014 and 2015. Although there was a 28.7% decrease between 2010-2012 and 2014-2015 in the number of exposures with PSS ≥2 per million units sold, this decrease was not statistically significant (p = 0.18). CONCLUSION: There is no evidence that the Product Stewardship Programme had a beneficial impact on the number of exposures reported to the National Poisons Information Service or their severity.
