ObjectivesTo examine the association between the number of visits to the emergency department (ED) by children for night-time headaches and exposure to multifaceted factors, such as meteorological conditions and air pollution.DesignWe conducted a clinical observational time-series analysis study.SettingWe reviewed consecutive patients younger than 16 years of age at the primary ED centre in Kobe city, Japan, during the night shift (19:30–7:00 hours) between 1 January 2011 and 31 December 2019.ParticipantsIn total, 265 191 children visited the ED; 822 presented with headache during the study period.Primary outcome measuresWe investigated the effects of meteorological factors and air pollutants by multivariate analysis of Poisson regression estimates. A subanalysis included the relationship between the number of patients with night-time headaches and the above factors by sex. Furthermore, the effect of typhoon landing on patient visits for headache was also analysed. Headache was not classified because examinations were performed by general paediatricians (non-specialists).ResultsThe number of patients with night-time headaches displayed distinct seasonal changes, with peaks during the summer. Multivariate analysis of Poisson regression estimates revealed a significant positive relationship between the number of patients for headache and mean temperature. Subanalysis by sex indicated a positive relationship between the number of patients with headache and mean temperature in both sexes; however, it was significant only for females. No relationship was found between the number of patients with headache and air pollution. There was no change in the number of patients for night-time headaches 3 days before and after typhoon landing.ConclusionsHigh temperature is the main factor for visiting ED for night-time headaches among children in Kobe city. Our results suggest that preventive measures against night-time headaches may be possible by reducing time spent outside during summer.

Background Front-line health-care services are under increased demand when acute alcohol intoxication is most common, which is in night-time environments. Cities have implemented alcohol intoxication management services to divert the intoxicated away from emergency care. Objectives To evaluate the effectiveness, cost-effectiveness and acceptability to patients and staff of alcohol intoxication management services and undertake an ethnographic study capturing front-line staff’s views on the impact of acute alcohol intoxication on their professional lives. Methods This was a controlled mixed-methods longitudinal observational study with an ethnographic evaluation in parallel. Six cities with alcohol intoxication management services were compared with six matched control cities to determine effects on key performance indicators (e.g. number of patients in the emergency department and ambulance response times). Surveys captured the impact of alcohol intoxication management services on the quality of care for patients in six alcohol intoxication management services, six emergency departments with local alcohol intoxication management services and six emergency departments without local alcohol intoxication management services. The ethnographic study considered front-line staff perceptions in two cities with alcohol intoxication management services and one city without alcohol intoxication management services. Results Alcohol intoxication management services typically operated in cities in which the incidence of acute alcohol intoxication was greatest. The per-session average number of attendances across all alcohol intoxication management services was low (mean 7.3, average minimum 2.8, average maximum 11.8) compared with the average number of emergency department attendances per alcohol intoxication management services session (mean 78.8), and the number of patients diverted away from emergency departments, per session, required for services to be considered cost-neutral was 8.7, falling to 3.5 when ambulance costs were included. Alcohol intoxication management services varied, from volunteer-led first aid to more clinically focused nurse practitioner services, with only the latter providing evidence for diversion from emergency departments. Qualitative and ethnographic data indicated that alcohol intoxication management services are acceptable to practitioners and patients and that they address unmet need. There was evidence that alcohol intoxication management services improve ambulance response times and reduce emergency department attendance. Effects are uncertain owing to the variation in service delivery. Limitations The evaluation focused on health service outcomes, yet evidence arose suggesting that alcohol intoxication management services provide broader societal benefits. There was no nationally agreed standard operating procedure for alcohol intoxication management services, undermining the evaluation. Routine health data outcomes exhibited considerable variance, undermining opportunities to provide an accurate appraisal of the heterogenous collection of alcohol intoxication management services. Conclusions Alcohol intoxication management services are varied, multipartner endeavours and would benefit from agreed national standards. Alcohol intoxication management services are popular with and benefit front-line staff and serve as a hub facilitating partnership working. They are popular with alcohol intoxication management services patients and capture previously unmet need in night-time environments. However, acute alcohol intoxication in emergency departments remains an issue and opportunities for diversion have not been entirely realised. The nurse-led model was the most expensive service evaluated but was also the most likely to divert patients away from emergency departments, suggesting that greater clinical involvement and alignment with emergency departments is necessary. Alcohol intoxication management services should be regarded as fledgling services that require further work to realise benefit. Future work Research could be undertaken to determine if a standardised model of alcohol intoxication management services, based on the nurse practitioner model, can be developed and implemented in different settings. Future evaluations should go beyond the health service and consider outcomes more generally, especially for the police. Future work on the management of acute alcohol intoxication in night-time environments could recognise the partnership between health-care, police and ambulance services and third-sector organisations in managing acute alcohol intoxication.

AbstractIntroduction:Many emergency departments (EDs) in the United States experience daily overcrowding, and a rapid influx of evacuees fleeing a disaster area can pose a substantial burden. Some of these evacuees may require ED care. However, others lack an alternative to the ED to address non-emergent medical concerns (prescription refills or outpatient referral).Objective:The objective of this study was to describe a successful multidisciplinary Hurricane Katrina Evacuation Center, explain the services offered, and determine the center's effects on referrals to local EDs.Methods:Data were collected concerning the number of patients utilizing the medical evaluation center and compared to the total number of evacuees to determine the proportion that utilized medical care. The data concerning patients given prescriptions was obtained by the estimation of the two medical directors of the Center, and therefore, is inexact.Results:During the five weeks the center was operational, 631 of 716 evacuees (88%) requested medical evaluation, and >80% of those had prescriptions written. Only four (<1%) patients were transported to local EDs.Conclusion:An evacuee evaluation center provides a convenient non-ED alternative for evacuees to address their non-emergent medical concerns and can be used to ease their transition to a new location.
