The Republic of Kosovo is a small country in the Balkans. The capital city of Pristina hosts most of its population and is situated in a mountain basin with poor air exchange, especially during winter. Domestic heating, road transport, industry and coal-fired power plants contribute to high levels of air pollution. We performed a time-series analysis on effects of particulate air pollution (PM2.5) on respiratory health of children and adolescents, using hospital admission and ambulatory visit numbers from the pediatric university clinic. From 2018 until 2020, daily mean concentrations of PM2.5 ranged between 2.41 and 161.03 µg/m³. On average, there were 6.7 ambulatory visits per day with lower numbers on weekends and during the first COVID-19 wave in 2020. An increase in PM2.5 led to an immediate increase in visit numbers that lasted over several days. Averaged over a full week, this amounted to about a 1% increase per 10 µg/m³. There were, on average, 1.7 hospital admissions per day. Two and three days after a rise in air pollution, there was also a rise in admission numbers, followed by a decline during the consecutive days. This might indicate that the wards were overstressed because of high admission numbers and restricted additional admissions.

“…The degree of freedom for the equation are found to be 7 for Time t , W S t and DOY t . The degree of freedom for Temp t and RH t is 3 according to the previous study [14][15][16][17][18]. Air pollution may have a delayed effect, hence each single-pollutant model was evaluated for impacts on the current day (lag 0) and the exposure to the seven days prior (lag 7) or even 30 days prior (lag 30).…”

Numerous studies have been conducted in other countries on the health effects of exposure to particulate matter with a diameter of 10 microns or less PM10 , but little research has been conducted in Malaysia, particularly during the haze season. This study intends to investigate how exposure of PM10 influenced hospital admissions for respiratory diseases during the haze period in peninsular Malaysia and it was further stratified by age group, gender and respiratory diseases categories. The study includes data from all patients with respiratory diseases in government hospitals, as well as PM10 concentration and meteorological data from all monitoring stations in peninsular Malaysia starting from 1st January 2000 to 31st December 2019. A quasi-poison time series regression with distributed lag nonlinear model (DLNM) was employed in this study to examine the relationship between exposure of PM10 and hospital admissions for respiratory diseases during the haze period. According to the findings of this study, PM10 was positively associated with respiratory disease admissions within 30 lag days under various lag patterns, with lag 25 showing the strongest association (RR = 1.001742,CI : 1.001029,1.002456). Using median as a reference, it was discovered that females were more likely than males to be hospitalized for PM10 exposure. Working age group will be the most affected by the increase in PM10 exposure with a significant cumulative RR from lag 010 to lag 030. The study found that PM10 had a significant influence on respiratory hospitalisation in peninsular Malaysia, particularly for lung diseases caused by external agents(CD5). Therefore, it is important to implement effective intervention measures to control PM10 and reduce the burden of respiratory disease admissions

“…Air pollution and climate change have become global health concerns. Particulate matter contributes to more hospital admissions [ 1 , 2 ], higher disease incidence [ 3 ], excess mortality [ 4 , 5 ], and increased stress in hospital management systems such as emergency ambulance dispatches [ 6 , 7 ]. Therefore, understanding the associations between air pollution and the incidence of various diseases can help vulnerable groups to take preventive measures in their daily lives.…”

There is limited evidence concerning the association between air pollution and different outpatient visits in moderately polluted areas. This paper investigates the effects of moderate-level air pollution on outpatient visits associated with six categories of clinic department. We analyzed a total of 1,340,791 outpatient visits for the pediatric, respiratory, ear-nose-throat (ENT), cardiovascular, ophthalmology, and orthopedics departments from January 2016 to December 2018. A distributed lag nonlinear model was used to analyze the associations and was fitted and stratified by age and season (central heating season and nonheating season). We found SO2 had the largest effect on pediatrics visits (RR = 1.105 (95%CI: 1.090, 1.121)). Meanwhile, PM2.5 and SO2 had greater effects on ENT visits for people under 50 years old. The results showed a strong association between O3 and cardiovascular outpatient visits in the nonheating season (RR = 1.273, 95% CI: 1.189,1.358). The results showed every 10 μg/m3 increase in SO2 was associated with a lower number of respiratory outpatient visits. Significant different associations were observed in PM2.5, NO2, CO, and O3 on ophthalmology visits between the heating and nonheating seasons. Although no significant association has been found in existing studies, our findings showed PM2.5 and NO2 were significantly related to orthopedic outpatient visits for people under 60 (RR = 1.063 (95%CI: 1.032, 1.095), RR = 1.055 (95%CI: 1.011, 1.101)). This study also found that the effect-level concentrations of air pollutants for some clinic departments were lower than the national standards, which means that people should also pay more attention when the air quality is normal.
