The economic burden of tuberculosis in Cyprus. A probabilistic cost of illness study.

Background: Tuberculosis remains a major public health problem with considerable economic burden worldwide. The aim of this study was to estimate the economic burden of tuberculosis in Cyprus during 2009.  Methods: A retrospective probabilistic incidence-based cost of illness model was developed to calculate, from the societal perspective, the economic burden of the disease including direct medical costs, direct non-medical costs and indirect costs. The bottom-up approach (person-based data) was used for the calculation of direct costs while for the calculation of indirect costs the approach of human capital was employed. In addition, probabilistic sensitivity analysis with 1000 Monte Carlo simulations was performed in order to calculate a 95% Confidence Interval (CI). Results: Mean per patient cost of tuberculosis in Cyprus in 2009 was estimated at €12,882 (95% CI: €12,747.35 – €12,964.32). Direct medical costs accounted for 83.07% of the overall expenses, €10,675 per patient (95% CI: €10,462.07 – €10,780.59). Total direct non-medical costs of €355 (95% CI: €353.04 – 364.29) accounted for 2.77% of the overall expenses whereas 14.16% of the overall expenses were associated with the indirect cost of €1,820 (95% CI: €1,815.20 – €1,873.65). Conclusion: For the first time in Cyprus, the cost of tuberculosis was estimated using a probabilistic incidence-based cost of illness model.  Our study confirms that tuberculosis is an expensive disease for the society. In addition, it provides important information to policy makers for the comprehension of the economic consequences of tuberculosis so as they can draft the national health policy accordingly and strengthen surveillance of the disease

Smoking prevalence and associated risk factors among healthcare professionals in Nicosia general hospital, Cyprus: A cross-sectional study

Background: In recent years, a significant progress has been achieved globally in reduction of smoking among physicians and nurses, however, in some countries the smoking prevalence of health professionals is maintained at very high levels, without significant difference from the general population. This study aims to investigate the prevalence of smoking among physicians and nurses working at Nicosia General Hospital, as well as their knowledge and attitudes towards smoking cessation strategies. Methods: This is a cross-sectional questionnaire-based study. The study consisted of 119 doctors and 392 nurses currently working at Nicosia General Hospital in Cyprus. Study participants were recruited from all hospital wards between May and June 2008. Both physicians and nurses were asked to answer an anonymous questionnaire, which included questions regarding their smoking habits, knowledge and attitudes about smoking and smoking cessation strategies. Results: Overall smoking prevalence among healthcare professionals was 28.2 % (28.6 % among physicians and 28.1 % among nurses). Multivariate analysis revealed that being male, younger than 34 years old, unmarried and with a family history of smoking were associated with increased likelihood of being a current smoker. An impressive 72 % of current smokers reported that they wished to quit smoking, however, only 5.6 % of physicians and 6.9 % of nurses, reported ever using any smoking cessation aids. Never- smokers counseled their patients to quit smoking more often (96.4 %) compared to former (84.6 %) and current smokers (72.7 %), (p < 0.001). In addition, those who felt more confident about their knowledge regarding smoking cessation, reported counseling their patients to quit smoking more often compared to those who did not (92 % vs 60 %, p < 0.001). Conclusions: Smoking prevalence among physicians and nurses working at Nicosia General Hospital was similar to that of the general Cypriot population. Further training of healthcare professionals towards smoking cessation strategies is needed in order to improve their knowledge and consequently their efforts on counseling and support to their patients who wish to quit smoking

The economic burden of adult asthma in Cyprus; a prevalence-based cost of illness study

Abstract Background Asthma is one of the main non-infectious diseases of the respiratory system with substantial economic burden worldwide. The objective of this study was to estimate the economic burden of adult asthma in Cyprus during 2015. Methods A retrospective probabilistic prevalence-based cost of illness model was developed to calculate the economic burden of asthma including direct and indirect costs. The bottom-up approach (person-based data) was used for the calculation of direct costs while for the calculation of indirect costs the approach of human capital was employed. In addition, bootstrapped sensitivity analysis with 1000 bootstrap simulations was performed in order to calculate a 95% Confidence Interval (CI). Results Mean patient cost of asthma in Cyprus in 2015 was estimated at €579.64 (95% CI: €376.90–€813.68). Direct costs accounted for 82.08% of the overall expenses, €475.75 per patient (95% CI: €296.94–€697.69). Indirect costs of €103.89 (95% CI: €49.59–€181.46) accounted for 17.92% of the overall expenses. Conclusion This was the first study in Cyprus, which used bootstrapped prevalence-based cost of illness model to estimate the cost of asthma. This study confirms that asthma is an expensive disease for the society. In addition, it provides important information and analysis of the economic consequences of asthma to policy makers in order to strengthen surveillance of the disease as well as draft the national health policy accordingly

Setting Objective Clinical Assessment Tools for Circadian Rhythm Sleep-Wake Disorders - A Community-Based Cross-Sectional Epidemiological Study

Introduction Circadian rhythm sleep-wake disorder (CRSWD) is an often-misdiagnosed group of sleep disturbances with limited data concerning diagnostic and therapeutic algorithms in the general population. Therefore, reported prevalence varies in the literature due to different case definitions, methodological, and environmental factors. Objectives The purpose of our cross-sectional study was to estimate the prevalence of CRSWD in the general population of Cyprus and to suggest clinical parameters for the assessment of atypical sleep schedules. The estimation was carried out by introducing normal preset sleep time limits, according to the imposed local environment and by administering well-established questionnaires for symptoms and consequence dysfunction, as objective evaluation tools. Methods In a nationwide epidemiological survey, 4118 Cypriot adult participants, selected and stratified to represent the general population, were interviewed on sleep habits and complaints by computer-assisted telephone interviewing (CATI). In the second stage, 250 adults were randomly selected from the initial representative sample, for a CRSWD assessment. According to the proposed diagnostic criteria, patients were interviewed about sleepiness and/or insomnia, and daytime dysfunction (fatigue, anxiety, and depression). They were also assessed by a weekly sleep diary for sleep schedules. Finally, all participants underwent a Type III Sleep Study, to rule out obstructive sleep apnea. Results From 195 enrolled participants (response rate 78%), 25 individuals (12.8%) met the criteria for CRSWD. The two most prevalent disorders were delayed sleep-wake phase disorder (DSWPD) (10pts, 5.1%) and shift work sleep disorder (SWD) (13, 6.7%). Less prevalent disorders included irregular sleep-wake rhythm disorder (ISWRD) (1, 0.5%) and advanced sleep-wake phase disorder (ASWPD) (1, 0.5%). Conclusions According to our data, CRSWDs are common in the general population of Cyprus, especially DSWPD and SWD. Affected individuals usually suffer from sleep deprivation and complain about insomnia, sleepiness and depression

The Complex Interaction Between the Major Sleep Symptoms, the Severity of Obstructive Sleep Apnea, and Sleep Quality

Introduction: Little information exists in the general population whether clinical presentation phenotypes of obstructive sleep apnea (OSA) differ in terms of sleep quality and comorbidities.Aim: The purpose of our study was to assess possible differences between symptomatic and asymptomatic OSA patients concerning syndrome's severity, patients' sleep quality, and comorbidities.Subjects and methods: First, in a nationwide, stratified, epidemiological survey, 4,118 Cypriot adult participants were interviewed about sleep habits and complaints. In the second stage of the survey, 264 randomly selected adults underwent a type III sleep study for possible OSA. Additionally, they completed the Greek version of Pittsburgh Sleep Quality Index (Gr-PSQI), Epworth Sleepiness Scale (ESS), Athens Insomnia Scale (AIS), and Hospital Anxiety and Depression Scale (HADS).Results: From 264 enrolled participants, 155 individuals (40 females and 115 males) were first diagnosed with OSA. Among these 155 patients, 34% had ESS ≥ 10 and 49% AIS ≥ 6. One or both symptoms present categorized the individual as symptomatic (60%) and neither major symptom as asymptomatic (40%). There were no significant statistical differences (SSDs) between the two groups (symptomatic–asymptomatic) with regard to anthropometrics [age or gender; neck, abdomen, and hip circumferences; and body mass index (BMI)]. The two groups had no differences in OSA severity—as expressed by apnea–hypopnea index (AHI), oxygen desaturation index (ODI), and mean oxyhemoglobin saturation (SaO$_{2}$)—and in cardiometabolic comorbidities. Symptomatic patients expressed anxiety and depression more often than asymptomatics (p &lt; 0.001) and had poorer subjective sleep quality (Gr-PSQI, p &lt; 0.001). According to PSQI questionnaire, there were no SSDs regarding hours in bed and the use of sleep medications, but there were significant differences in the subjective perception of sleep quality (p &lt; 0.001), sleep efficiency (p &lt; 0.001), duration of sleep (p = 0.001), sleep latency (p = 0.007), daytime dysfunction (p &lt; 0.001), and finally sleep disturbances (p &lt; 0.001).Conclusion: According to our data, OSA patients reporting insomnia-like symptoms and/or sleepiness do not represent a more severe phenotype, by the classic definition of OSA, but their subjective sleep quality is compromised, causing a vicious cycle of anxiety or depression
