The study period ranged from January 1, 2018, to September 30, 2023, and was divided into four distinct periods: pre-epidemic, pandemic, normalized control, and end of control. Using a quasi-Poisson regression model, we examined the specific effects of these policies on emergency visits, with a particular focus on stratifying patients based on respiratory versus non-respiratory diseases.Results: Compared to the pre-pandemic period, the number of ED visits in a tertiary hospital decreased by 38.5% (95% CI: 25.1% to 49.8%) during the COVID-19 pandemic, of which the number of ED visits for respiratory diseases increased by 79.4% (95% CI: 13.2% to 177.2%) and the number of ED visits for non-respiratory diseases decreased by 45.9% (95% CI: − 55.7% to − 34.2%). After the end of the epidemic control, the total number of ED visits increased by 31.5% (95% CI: 19.1% to 45.0%), with the number of ED visits for respiratory diseases rising by 379.2% (95% CI: 275.9% to 511.8%), but with no significant change in the number of ED visits for non-respiratory emergencies.Conclusion: Control policies were associated with people avoiding emergency care for non-respiratory related reasons during the pandemic, while the end of control policies was associated with a sharp rise in emergency care for respiratory diseases. This study provides a scientific basis for the different changes in ED visits under the implementation of varying epidemic prevention and control policies.Keywords: COVID-19, health policy, emergency visit, respiratory disease, interrupted time series analysis

Individuals with a schizophrenia spectrum disorder were at heightened risk for interruptions in psychiatric care during the coronavirus-19 (COVID 19) pandemic. There is limited work exploring the pandemic's impact on emergency department (ED) visit volume, use of restraint and parenteral medications, inpatient psychiatric (IP) hospitalization, and ED length of stay (LOS) among this population. We retrospectively examined 2134 ED visits with a billing code for psychosis between March 1, 2019-February 28, 2021. We used Poisson regression analysis to compare ED visit volume between the pandemic and pre-pandemic periods. Restraint use, parenteral antipsychotic or benzodiazepine use, IP hospitalization, and ED LOS were compared between the two periods using chi-square tests and independent samples t -tests. Overall volume of psychosis-related ED visits during the pandemic did not differ significantly from the prior year. Rates of restraint use (16.2 % vs 11.6 %, p <.01), parenteral antipsychotic (22.6 % vs 14.9, p <.001), and parenteral benzodiazepine (22.3 % vs 16.3 %, p <.001) use were significantly higher during the pandemic. Fewer patients had an IP hospital disposition during the pandemic than the year prior (57.8 % vs. 61.9 %, p <.05). ED LOS was longer during the pandemic compared to pre-pandemic (28.37 h vs 20.26 h, p <.001). Although the volume of psychosis-related ED visits remained constant, restraint and parenteral medication use rates were significantly higher during the pandemic. ED LOS increased but fewer ED visits resulted in IP hospitalization. These findings underscore the importance of planning for increased acuity of psychosis ED presentations during public health emergencies. [ABSTRACT FROM AUTHOR]

A retrospective cross-sectional analysis was performed to understand the characteristics of critically ill patients and compare the proportion of hospitalizations, deaths, and emergency ambulance calls (EACs).Results: The number of patients presenting to the ED was significantly decreased, with a 37.75% reduction in 2020 (6196) compared to the same period in 2019 (9954). A rise in patient ED presentations was observed in the same period in 2021 (10,503). This decline was mostly in the 15– 45 age group. In 2019, 2020, and 2021, critically ill patients treated by the ED totaled 568 (5.706%), 339 (5.495%), and 590 (5.617%), respectively. Compared to the same period in 2019 and 2021, the proportion of critically ill patients with respiratory system involvement, severe trauma, and poisoning decreased most significantly in 2020 (P< 0.05). In contrast, the rates of EACs, hospitalizations, and deaths increased significantly (P< 0.05).Conclusion: The number of ED visits to hospitals was decreased during the 2020 lockdown, while the rates of EACs, hospitalizations, and deaths increased significantly though there were no documented COVID-19 cases. Optimizing emergency medical resources and ensuring the safety of healthcare providers and patients were essential to provide efficient emergency diagnosis and treatment during the lockdown.Keywords: COVID-19 pandemic, emergency medicine, coping strategies, emergency visit, non-COVID-19 patients

We evaluated costs for respiratory syncytial virus (RSV) medical attention in children aged <24 months using MarketScan® Medicaid Multi-State claims database 2015–2019. Average cost was highest for RSV hospitalization with intensive care unit (ICU) admission ($23 514–24 835), followed by no ICU admission ($8039–8990), ED visits ($463–482), and outpatient visits ($145–151). Cost was higher for those with comorbidities. [ABSTRACT FROM AUTHOR]

Abstract Aim To determine the effectiveness of nurse‐led discharge service for adult surgical inpatients. Design The report of this review was conducted by the preferred reporting items for systematic reviews and meta‐analyses (PRISMA) statement checklist. Methods The PubMed, Web of Science, ScienceDirect, Cochrane Library (CENTRAL), MEDLINE and Embase as well as four Chinese databases including CNKI, Wanfang database, VIP database and CBM were searched for randomized controlled trials. Two reviewers independently extracted data and assessed risk of bias. And meta‐analyses were conducted for the eligible studies by Review manager 5.4.1. Results A total of 1,649 participants were enrolled in 12 randomized controlled trials. The result of readmission rate and emergency visit of intervention group were lower than those of the control group; activities of daily living and quality of life in the intervention group were higher than that of the control group. There was no statistical difference in the length of stay between the two groups.

Background: The COVID‐19 pandemic has changed the epidemiology of acute respiratory infections (ARIs) in children. The aims of the present study were to describe the epidemiological trend of ARI emergency visits and virology results prior and after the SARS‐CoV‐2 emergence and to estimate the association of ARI emergency department (ED) visits with respiratory viruses. Methods: This study was conducted at the Bambino Gesù Children's Hospital, a tertiary care children's hospital in the Lazio Region, Italy. The demographic and clinical information of children who accessed the ED and were diagnosed with ARI from January 1, 2018 to June 30, 2022 was retrospectively extracted from the electronic health records. The observed temporal trends in viruses diagnosed from respiratory samples were compared with the number of ARI ED visits over the same period through a multivariable linear regression model. Results: During the study period, there were 72,959 ED admissions for ARIs and 33,355 respiratory samples resulted positive for viruses. Prior to the pandemic, respiratory syncytial virus (RSV) and influenza had a clear seasonal pattern, which was interrupted in 2020. In 2021–2022, RSV reached the highest peak observed during the study period, whereas influenza activity was minimal. The peaks of ARI ED visits corresponded to peaks of influenza, RSV, and rhinovirus in the 2018–2019 and 2019–2020 seasons, to SARS‐CoV‐2 and rhinovirus in 2020, and to RSV and parainfluenza in 2021–2022. Conclusions: ARI resulting in ED visits should be included in the ARI disease burden measurement for a more accurate measure of the impact of preventive measures. [ABSTRACT FROM AUTHOR]

Background: Ramadan is the ninth month of the Islamic calendar were Muslims fast from dawn until sunset. This prolonged fasting period might have an impact on patients with diabetes and their disease control. This study aimed to determine the variation in visits at the Emergency Room department (ER) during Ramadan in comparison with other lunar months at a tertiary care hospital in Jeddah city in relation to the diabetes emergencies.Methodology: A retrospective cross-sectional study was conducted using electronic medical record review of patients with diabetes emergencies who visited ER of a Military hospital, from 9th to 11th lunar months during 2017-2018. Diabetes patients who visited ER and aged more than 18 years old were included. Frequency of ER visits, sociodemographic characteristics and clinical features were determined. Chi-square test, Student 's t-test and one-way ANOVA at p < 0.05 were used in assessing associations between variables.Results: Within the selected study period, a total of 24,498 admissions were recorded in ER. The prevalence of diabetes emergencies visits was only 0.84%. Based on inclusion criteria, a total of 133 subjects were included in the study (54.1% men, 45.9% women). Majority of whom (73.7%) were on insulin therapy, and more than half of whom (51.9%) were type 2 diabetes. There was a significant difference (p = 0.001) in the prevalence of diabetes emergencies visits between the three lunar months Shaban, Ramadan and Shawal, 7, 5 and 4%, respectively. However, the highest prevalence was not in Ramadan. Despite some correlations were identified, the study found no significant differences between frequency of ER visits and various demographic, clinical factors and diabetes profile between Ramadan and other both preceding and succeeding lunar month.Conclusion: In contrary with previous studies, a downward trend of prevalence, from Shaban to Ramadan, to Shawal was found. This indicated that fasting during month of Ramadan does not impact negatively on the diabetes emergencies in comparison with other months. Hyperglycemia among type 2 diabetes and insulin treated patients were recorded the highest feature of diabetes emergences visits during the three months studied with no significant differences between the months. These findings highlight the need of type 2 and insulin treated patients to be thoroughly assess by the Primary Care physicians and in-depth health education and guidance should be given to them.

Background: Anaphylaxis is a recognized public health issue. There is no doubt that food‐induced anaphylaxis (FIA) has tremendous impact on the quality of life of patients and their families and increases direct and indirect costs. FIA is associated with increasing rates of emergency department admissions and hospitalizations and implies the risk of death. Morbidity epidemiological data are a key to tailor public health actions to this non‐communicable disease. The aim of this article was to review published morbidity epidemiological data relating to FIA and potential risk factors, in order to provide evidence‐based recommendations to reduce the risk of severe adverse outcomes. Methods: We identified published studies available in PUBMED/MEDLINE (1966–2020), EMBASE (1980–2020) and CINAHL (1982–2020). The systematic review was carried out using MeSH terms related to FIA ED admissions and hospitalizations. Results: A total of 25 articles were selected, 80% published in the last 5 years. After critical analysis of methodological and clinical characteristics reported in the data selected, we were able to propose preventive strategies. Conclusion: Anaphylaxis is a recognized public health issue. FIA is associated with increasing rates of ED admissions and hospitalizations and imply in risk of death. More than reviewing and critically interpreting the key patterns related to FIA morbidity published data, we proposed strategies in order to promote quality care of patients suffering from FIA. Our World Health Organization Collaborative Center is deeply involved in this process, and we believe that the proposed strategies will inform future healthcare policies on anaphylaxis. The long‐term objective would be to improve clinical care and quality of life of patients and their families, and develop risk‐stratified, cost‐effective preventive measures. [ABSTRACT FROM AUTHOR]

Objective: We assessed the prevalence and consequences of discordant language communication between bilingual Swedish speaking emergency patients and general practitioners (GPs) in Finnish healthcare. We compared the results with Finnish speaking emergency patients provided with language concordant healthcare. Materials and Methods: A researcher-designed questionnaire was used to collect data about both Swedish and Finnish speaking emergency patients' health and socioeconomic status, reason for emergency visits and use of healthcare. Furthermore, the Swedish speakers' nonnative language proficiency and preferred communication language were examined. The study was performed in 16 healthcare centers and outpatient departments in bilingual regions in Finland. Results: The Swedish speakers (n = 139) visited healthcare centers less than the Finnish speakers (n = 736) (P = 0.001) and communicated less frequently with the GP in their native language (P < 0.001). The Swedish speakers more often planned to revisit their assigned GP (P < 0.001) after the emergency visit. No differences in health conditions and socioeconomic status between the language groups were observed. Conclusion: Although Swedish and Finnish speaking emergency patients report a similar prevalence of chronic noncommunicable diseases, Swedish speakers make fewer annual visits to a physician. We suggest that discordant language communication might relate to decreased healthcare visits among bilingual Swedish speaking emergency patients.

Objective: To derive findings from different studies done on drug related hospital admissions and comprehensively express the incidence and preventability of drug related hospital admissions; identify the common types of drug related problems that caused hospital admission, and identify factors associated with drug related hospital admission. Methods: Literatures that assessed hospitalization due to drug related problems were searched online using Pub Med and Google Scholar databases. The relevant reference lists of retrieved articles were also searched manually on Google. Prospective and retrospective studies conducted anywhere in the world on drug related hospitalization, published from January 2012 to January 2017 as an original article and written in English language were included. Result: The prevalence of drug related hospital admission varies from 1.3% to 41.3% with the average rate of 15.4%. Among hospitalized patients 2.7% were died due to drug-related problems (DRPs). Drugs that were frequently reported as causing drug related admission were antithrombotic drugs, antihypertensive drugs, analgesics, anti-diabetics, antipsychotics, and anti-neoplastic drugs. Poly pharmacy, old age and female sex were mentioned as determinants for drug related hospitalization by a number of studies. About one third of drug related hospital admissions were definitely preventable and more than 40% were also potentially preventable. Conclusion: Drug related problems contribute for more than 15% of hospital admissions. Higher risk of admission due to DRPs was observed in patients who were on poly pharmacy and those who were old. As most of drug related hospital admissions were preventable an emphasis should be given for preventive strategies to avoid complications and costs associated with admission.

Abstract Background Age increases the risk of emergency department [ED] visits. Health related quality of life (HRQoL) is often estimated as an outcome of ED visits, but it can be a risk factor of ED visits. This study aims to assess the association of HRQoL with time to first ED visit and/or frequent ED use in older adults during four-year period and if this association differs in 66–80 and 80+ age groups. Methods Data from the Swedish National Study on Aging and Care-Blekinge of wave 2007–2009 was used in combination with electronic health records on ED visits. The analytical sample included 673 participants of age 66 years and older with information on HRQoL. Cox proportional hazard model was used to assess the association between HRQoL and time to first ED visit. Logistic regression analysis was performed to estimate the association of HRQoL with frequent ED use. Results During the study period, 55.3% of older adults visited the ED and 28.8% had a frequent ED use. Poor physical HRQoL was independently associated with first ED visit both in total sample (p

Objectives: Barriers to timely access to usual sources of medical care lead patients to use the emergency department as a ready alternative. This study aims to determine the characteristics of patients who use medical resources on Sundays. We also examined the relationship between emergency department visits and barriers to receiving usual sources of care in a timely manner for loyal patients. Methods: Data from 2016 to 2018 were obtained from Taiwan’s National Health Insurance Research Database, and the study estimated of medical care utilization in the past year. Patients were classified as having a usual source of care if they made 80% or more of their total ambulatory visits to the same clinic. Descriptive statistics and logistic regression analyses were used to determine relationships between the medical service provided on Sundays and the use of the emergency department by loyal patients. Results: This study included 2,952,002 ambulatory and emergency department visits from 1,449,968 loyal patients. Patients who had a higher risk of emergency visits had the following characteristics: male, over 65 years of age, low-income, co-morbidities, major injuries, poor physical health, or poor mental health. In terms of medical use, the following was also associated with a higher risk of emergency visits by patients: low outpatient visits, having a record of hospitalization in the past year, after-hours visits, medical needs for surgery, or pediatrics. The positive associations between barriers to receiving usual source of care in a timely manner and emergency department usage persisted even in multiple logistic regressions that adjusted for patient characteristics, medical use, and characteristics of medical institutions. The risk of emergency department visits was significantly higher among loyal patients whose usual clinics did not provide medical services that met their needs than among patients whose usual clinics did meet their needs (OR=12.72, 95%CI:12.56-12.87). Conclusions: The results indicate that loyal patients who have barriers to their usual source of medical care are more likely to utilize the emergency department. Improving the availability and accessibility of primary medical care on Sundays may help reduce rates of emergency department use and resolve current situations of unmet medical needs.

Background: Intimate partner violence (IPV) refers to physical or sexual violence, stalking, and psychological aggression by an intimate partner. The present study aims to examine the incidence, injury patterns, and outcomes using a representative nationwide data set.Study Design: The Nationwide Emergency Department Sample database was queried from 2010 to 2014 to identify IPV in adult patients by injury code E967.3. Demographics, diagnoses, and injury mechanisms were captured. Primary outcome was mortality, and logistic regression analyses were used to compare the baselines and outcomes.Results: 132 806 IPV emergency visits were identified, with 5.1% of patients requiring hospitalization. Most patients were female (92.6%). The most common injury mechanisms were unintentional injury (36%) and striking (22.0%). Contusions of face/scalp/neck (13.2%) and unspecified head injury (6.9%) were the most common diagnoses. Males were significantly older [median and interquartile range of 39 (30, 50)] than females [33 (26, 43)], and were more frequently hospitalized (6.7% vs. 5.0%, P = .002) with more injuries with injury severity score ≥ 15 (.7% vs. .4%, P = .004) than females. Overall, IPV-related mortality was .06%, .26% in males and .05% in females (P = .003). Older age (odds ratio (OR) = 1.053) and male gender (OR = 3.102) were significantly associated with mortality. The annual incidence rate decreased from 9.7 in 2010 to 8.2/100 000 US population in 2014 (R2 = .659).Conclusions: Young women are more likely to be victims of IPV, whereas men are more likely to be older and hospitalized with more severe injuries and worse outcomes.

Purpose: Psychosocial and biological factors influence the perception of physical changes during pregnancy. Some pregnant women present to the obstetric emergency department (ED) with diverse symptoms not requiring urgent medical action. These visits result in over-consultation, tying up resources and inflating health care expenses. This study outlines factors associated with multiple ED visits during pregnancy, measures the prevalence of anxiety and depression, and explores the choice of maternity clinic for delivery aiming to elucidate options for care strategies. Methods: This prospective, cross-sectional, questionnaire-based bicentric study was performed in the obstetric outpatient departments of two university hospitals in Germany and recruited pregnant women between 12/2016 and 11/2017. The questionnaire included socio-demographics, obstetric history, anxiety (GAD-7), depression (PHQ-9), and health status (WHO-5, SF-12). Results: This analysis included 496 women and showed that women with numerous ED visits were significantly younger (p < 0.0001), less educated (p = 0.0002), and more likely to be unemployed and single. Different prevalences for anxiety and depression were detected correlating with the number of ED visits although each showing only low effect sizes (0.024 resp. 0.015). Conclusions: Pregnant women attending the ED more often might benefit from health education, psychosomatic interventions, and social support to overcome their depression and anxiety to avoid non-urgent ED consultations. Further prospective studies are needed to support these findings. [ABSTRACT FROM AUTHOR]

We suggest that discordant language communication might relate to decreased healthcare visits among bilingual Swedish speaking emergency patients. [ABSTRACT FROM AUTHOR]

Background: We are a tertiary care cancer center and have approximately 1000–1500 emergency visits by cancer patients undergoing treatment under the adult medical oncology unit each month. However, due to the lack of a systematic audit, we are unable to plan steps toward the improvement in quality of emergency services, and hence the audit was planned. Methods: All emergency visits under the adult medical oncology department in the month of July 2015 were audited. The cause of visit, the demographic details, cancer details, and chemotherapy status were obtained from the electronic medical records. The emergency visits were classified as avoidable or unavoidable. Descriptive statistics were performed. Reasons for avoidable emergency visits were sought. Results: Out of 1199 visits, 1168 visits were classifiable. Six hundred and ninety-six visits were classified as unavoidable (59.6%, 95% CI: 56.7–62.4), 386 visits were classified as probably avoidable visit (33.0%, 95% CI: 30.4–35.8) whereas the remaining 86 (7.4%, 95% CI: 6.0–9.01) were classified as absolutely avoidable. Two hundred and ninety-seven visits happened on weekends (25.6%) and 138 visits converted into an inpatient admission (11.9%). The factors associated with avoidable visits were curative intention of treatment (odds ratio - 2.49), discontinued chemotherapy status (risk ratio [RR] - 8.28), and private category file status (RR – 1.89). Conclusion: A proportion of visits to emergency services can be curtailed. Approximately one-fourth of patients are seen on weekends, and only about one-tenth of patients get admitted.

PURPOSE: Awareness of symptoms and signs of possible complications after corneal transplantation is very important. Early presentation can enhance long-term survival of the cornea. This study evaluates the reasons for emergency presentation and management of postcorneal transplantation complications. PATIENTS AND METHODS: This retrospective study included a total of 134 postkeratoplasty patients at the cornea unit in Yemen Magrabi Eye Hospital in Sana'a between 2008 and 2010. RESULTS: The most common indication for keratoplasty was keratoconus in 103 patients (76.9%) followed by bullous keratopathy (4.5%) and corneal dystrophy (4.5%). 80 (59.7%) patients presented for emergency visits. Pain and foreign body sensation were the main presenting symptoms. Loose irritating sutures (29.9%) and graft rejection (10.4%) were the most common diagnoses. Twelve patients (8.9%) were admitted to the hospital for re-suturing. CONCLUSION: Proper postoperative care is critical for a successful keratoplasty; early intervention of sight-threatening complications increases the chance of graft survival and best-obtained vision. In our corneal transplantation service, all patients are routinely instructed to arrange a same day emergency visit if they experience any symptom in eyes that have undergone keratoplasty.

Inadequate emergency visits, which could be resolved in primary care, are an unnecessary expense for the healthcare service. We did a review of all gynaecology and obstetrics emergency visits by pregnant or postpartum women during 2010 and 2011 in order to describe the adequacy of the visits by pregnant women to the emergency service. We defined three levels of adequacy: adequate, moderately adequate, and inadequate. One thousand seven hundred and forty-three visits to the emergency room of gynaecology and obstetrics were studied. These consultation motivations were adequate in 38.9%, moderately adequate in 46.7% and inadequate in 14.4%. This shows that the amount of inadequate and moderately adequate visits to the emergency department could be reduced by 61% by implementing different interventions, and also reducing health spending for emergencies. Impact statement What is already known on this subject: Visits to the emergency room constitute a basic pillar in the hospital structure, and it generates great health expense. Other authors have reported high rates of inadequacy of these visits to the emergency services. They find inadequate visits are associated with young age and female gender among other factors. What the results of this study add: Knowing the adequacy of the visits generated by pregnant young women is a starting point for implementing health policies that could reduce these inadequate visits and consequently health expenditure could be reduced. What the implications are of these findings for clinical practice and/or further research: These health policies could consequently reduce health expenditure. [ABSTRACT FROM AUTHOR]

Objective: The relationship between acute exacerbation and exercise performance in chronic obstructive pulmonary disease (COPD) is unclear. The aim of this study was to compare exercise performance between patients with COPD who visited and did not visit an emergency department in the last year; we also aimed to investigate the correlation between frequency of emergency visits and exercise performance. Methods: We recorded the number of emergency department visits of 206 COPD patients. The six-minute walk test, the modified Medical Research Council Dyspnea Scale, body plethysmographs, carbon monoxide diffusion tests, and arterial blood gas analysis were practiced. Results: We had one hundred twenty seven participants visited an emergency department at least once in the last year. Exercise performance, dyspnea, pulmonary functions, and oxygenation were significantly poorer in those patients (p<0.05). The number of emergency department visits was correlated with exercise performance, dyspnea, oxygenation, forced expiratory volume in one second forced expiratory volume in one second/forced vital capacity, and carbon monoxide diffusion capacity (p<0.05). Conclusion: Exercise performance was poor and negatively related to the frequency of emergency department visits in COPD patients. We concluded that exercise performance-enhancing implementations may contribute to reduce the frequency of emergency department visits. [ABSTRACT FROM AUTHOR]

Objective.To evaluate determinants of increased emergency room (ER) visit and hospitalization among adults with asthma, with emphasis on the role of psychological distress, self-efficacy, and obesity.Methods:For analysis 2009, 2011/2012 California Health Interview Survey was used. Adults who reported lifetime asthma were selected. Association between ER and overnight hospital stay with population characteristics were conducted using chi-square analysis. Multivariable binary logistic regression models, taking into account control variables, were utilized to assess the relationship between ER visit or overnight hospital stay with that of psychological distress, self-efficacy, and obesity.Results:Odds of ER visits were higher among those with mild-to-moderate psychological distress (adjusted odds ratio [aOR] = 1.94, 95% CI: 1.28, 2.94), and among those with serious psychological distress (aOR = 2.62, 95% CI: 1.65, 4.16). Mild-to-moderate distress was associated with two-fold increase in hospital overnight stay (aOR = 2.05, 95% CI: 1.29, 3.25). Adults with asthma who reported low self-efficacy had increased ER visits (aOR = 6.21, 95% CI: 3.63, 10.65) and hospitalization (aOR = 4.13, 95% CI: 2.63, 6.49). Finally, adults who had asthma and were obese had higher odds of ER visits (aOR = 1.60, 95% CI: 1.20, 2.13).Conclusions:Healthcare utilization is higher among asthma patients with psychological distress, low self-efficacy, and obesity. Interventions, such as incorporation of integrated care models, are critical to ensure early screening of mental health status among such patients. In addition, there is a need for patient education and improved weight management among adults with asthma. [ABSTRACT FROM AUTHOR]

Few epidemiological studies have been reported as to whether there was any interactive effect between temperature and humidity on respiratory morbidity, especially in Asian countries. The present study used time-series analysis to explore the modification effects of humidity on the association between temperature and emergency room (ER) visits for respiratory, upper respiratory tract infection (URI), pneumonia, and bronchitis in Beijing between 2009 and 2011. Results showed that an obvious joint effect of temperature and humidity was revealed on ER visits for respiratory, URI, pneumonia, and bronchitis. Below temperature threshold, the temperature effect was stronger in low humidity level and presented a trend fall with humidity level increase. The effect estimates per 1 °C increase in temperature in low humidity level were −2.88 % (95 % confidence interval (CI) −3.08, −2.67) for all respiratory, −3.24 % (−3.59, −2.88) for URI, −1.48 % (−1.93, −1.03) for pneumonia, and −3.79 % (−4.37, −3.21) for bronchitis ER visits, respectively. However, above temperature threshold, temperature effect was greater in high humidity level and trending upward with humidity level increasing. In high humidity level, a 1 °C increase in temperature, the effect estimates were 1.84 % (1.55, 2.13) for all respiratory, 1.76 % (1.41, 2.11) for URI, and 7.48 % (4.41, 10.65) for bronchitis ER visits. But, there was no statistically significant for pneumonia. This suggests that the modifying effects of the humidity should be considered when analyzing health impacts of temperature.
