This study presents the relationships between ambient air pollutants and morbidity and emergency department visits among children and adults performed in Great Casablanca, the most populated and economic region in Morocco. This research was analyzed using conditional Poisson model for the period 2011–2013. In the period of study, the daily average concentrations of SO2, NO2, O3 and PM10 in Casablanca were 209.4 µg/m3, 61 µg/m3, 113.2 µg/m3 and 75.1 µg/m3, respectively. In children less than 5 years old, risk of asthma could be increased until 12% per 10 µg/m3 increase in NO2, PM10, SO2 and O3. In children over 5 years and adults, an increase of 10 µg/m3 air pollutant can cause an increase until 3% and 4% in respiratory consultations and acute respiratory infection, respectively. Similarly, impact on emergency department visits due to respiratory and cardiac illness was established. Our results suggest a not negligible impact on morbidity of outdoor air pollution by NO2, SO2, O3, and PM10. 相似文献

ObjectivesLittle is known about emergency department (ED) utilization among the nearly 1 million older adults residing in assisted living (AL) settings. Unlike federally regulated nursing homes, states create and enforce AL regulations with great variability, which may affect the quality of care provided. The objective of this study was to examine state variability in all-cause and injury-related ED use among residents in AL.DesignObservational retrospective cohort study.Setting and ParticipantsWe identified a cohort of 293,336 traditional Medicare beneficiaries residing in larger AL communities (25+ beds).MethodsWith Medicare enrollment and claims data, we identified ED visits and classified those because of injury. We present rates of all-cause and injury-related ED use per 100 person-years in AL, by state, adjusting for age, sex, race, dual-eligibility, and chronic conditions.ResultsRisk-adjusted state rates of all-cause ED visits ranged from 100.9 visits/100 AL person-years [95% confidence interval (CI) 92.8, 109.9] in New Mexico to 162.3 visits/100 AL person-years (95% CI 154.0, 174.7) in Rhode Island. The risk-adjusted rate of injury-related ED visits ranged from 18.7 visits/100 AL person-years (95% CI 17.2, 20.3) in New Mexico to 35.7 visits/100 AL person-years (95% CI 34.7, 36.8) in North Carolina.Conclusions and ImplicationsWe observed significant variability among states in all-cause and injury-related ED use among AL residents. There is an urgent need to better understand why this variability is occurring to prevent avoidable visits to the ED. 相似文献

ObjectiveTo describe nursing home residents’ (NHRs) functional trajectories and mortality after a transfer to the emergency department (ED).DesignCase-control observational multicenter study.Setting and ParticipantsIn total, 1037 NHRs presenting to 17 EDs in France over 4 nonconsecutive weeks in 2016.MethodsFinite mixture models were fitted to longitudinal data on activities of daily living (ADL) scores before transfer (time 1), during hospitalization (time 2), and within 1 week after discharge (time 3) to identify groups of NHRs following similar functional evolution. Factors associated with mortality were investigated by Cox regressions.ResultsTrajectory modeling identified 4 distinct trajectories of ADL. The first showed a high and stable (across time 1, time 2, and time 3) functional capacity around 5.2/6 ADL points, with breathlessness as the main condition leading to transfer. The second displayed an initial 37.8% decrease in baseline ADL performance (between time 1 and time 2), followed by a 12.5% recovery of baseline ADL performance (time 2?time 3), with fractures as the main condition. The third displayed a similar initial decrease, followed by a 6.7% recovery. The fourth displayed an initial 70.1% decrease, followed by an 8.5% recover, with more complex geriatric polypathology situations. Functional decline was more likely after being transferred for a cerebrovascular condition or for a fracture, after being discharged from ED to a surgery department, and with a heavier burden of distressing symptoms during transfer. Mortality after ED transfer was more likely in older NHRs, those in a more severe condition, those who were hospitalized more frequently in the past month, and those transferred for cerebrovascular conditions or breathlessness.Conclusions and ImplicationsIdentified trajectories and factors associated with functional decline and mortality should help clinicians decide whether to transfer NHRs to ED. NHRs with high functional ability seem to benefit from ED transfers whereas on-site alternatives should be sought for those with poor functional ability. 相似文献

ObjectivesTo investigate the association between rapid access to radiographs, blood tests, urine cultures, and intravenous (IV) therapy in a long-term care (LTC) home with resident transfers to the emergency department (ED).DesignRetrospective cohort study.Setting and Participants21,811 residents living in 162 LTC homes in Ontario, Canada.MethodsWe administered a survey to LTC homes to collect wait times for radiographs, basic blood tests, urine culture, and IV therapy. Rapid availability was defined as typically receiving test results within 1 or 2 days, or same-day IV therapy. We linked the survey results to administrative data and defined a cohort of residents living in survey-respondent homes between January and May 2017. We followed residents in the linked administrative databases for 6 months, until discharge, or death. Two physicians identified diagnostic codes for ED visits that were potentially preventable with rapid availability of each of the 4 resources. Multilevel logistic regression models estimated associations between potentially preventable ED visits and rapid diagnostic tests and intravenous access while controlling for demographic characteristics, illness severity, LTC home size, chain status, and physician availability.ResultsRapid blood tests, radiographs, urine culture, and IV therapy were available in 55%, 47%, 34%, and 45% of LTC homes, respectively. LTC homes that were part of multihome chains were less likely to have rapid access to the 4 resources. Of the 4736 residents (27%) who visited an ED during follow-up, individuals from homes with rapid access to radiographs (odds ratio 0.79, 95% confidence interval 0.66-0.97), urine culture (0.88, 0.72-1.08), blood tests (0.83, 0.69-1.00), and IV therapy (0.93, 0.70-1.23) tended to have fewer potentially preventable ED visits.Conclusions and ImplicationsRapid access to diagnostic testing and IV therapy in LTC reduced ED visits. Improving access to these resources may prevent ED visits and allow residents to stay home. 相似文献

ObjectiveThe quality of care provided by the US Department of Veterans Affairs (VA) is increasingly being compared to community providers. The objective of this study was to compare the VA Community Living Centers (CLCs) to nursing homes in the community (NHs) in terms of characteristics of their post-acute populations and performance on 3 claims-based (“short-stay”) quality measures.DesignObservational, cross-sectional.Setting and ParticipantsCLC and NH residents admitted from hospitals during July 2015–June 2016.MethodsCLC residents were compared with 3 NH populations: males, Veterans, and all NH residents. CLC and NH performance was compared on risk-adjusted claims-based measures: unplanned rehospitalizations and emergency department visits within 30 days of CLC or NH admission and successful discharge to the community within 100 days of NH admission.ResultsVeterans admitted from hospitals to CLCs (n = 23,839 Veterans/135 CLCs) were less physically impaired, less likely to have anxiety, congestive heart failure, hypertension, and dementia than Veterans (n = 241,177/14,818 NHs), males (n = 661,872/15,280 NHs), and all residents (n = 1,674,578/15,395 NHs) admitted to NHs from hospitals. Emergency department and successful discharge risk-adjusted rates of CLCs were statistically significantly better than those of NHs [mean (standard deviation): 8.3% (4.6%) and 67.7% (11.5%) in CLCs vs 11.9% (5.3%) and 57.0% (10.5%) in NHs, respectively]. CLCs had slightly worse rehospitalization rates [22.5% (6.2%) in CLCs vs 21.1% (5.9%) in NHs], but lower combined emergency department and rehospitalization rates [30.8% (0.8%) in CLCs vs 33.0% (0.7%) in NHs].Conclusions and ImplicationsCLCs and NHs serve different post-acute care populations. Using the same risk-adjusted NH quality metrics, CLCs provided better post-acute care than community NHs. 相似文献
