Public-Private Partnership (PPP) projects success is the ultimate goal of practitioners and government organizations. In this regard, the last decade has seen considerable research into the critical success factors (CSFs) for PPP projects. However, a very important subject which has received very little attention in the normative literature is the success criteria for PPP projects. This paper examines the general perception of purposively sampled international PPP experts on a set of 15 PPP projects success criteria derived from literature. The survey results show that all the success criteria are critical; however seven are very critical. These include: effective risk management; meeting output specifications; reliable and quality service operations; adherence to time; satisfying the need for public facility/service; long-term relationship and partnership; and profitability. The findings of this study are impactful because they inform practitioners on the key measures to consider when evaluating the success of PPP projects. More research should be conducted to further develop a composite success index that could be used to objectively assess the success levels of different PPP projects. In addition, the perceptions of different stakeholders on PPP projects success criteria and the causal relationship between CSFs and success criteria for PPP projects should be investigated.
In many countries, it is common practice to attract and employ ethnic minority (EM) or migrant workers in the construction industry. This primarily occurs in order to alleviate the labor shortage caused by an aging workforce with a lack of new entrants. Statistics show that EM construction workers are more likely to have occupational fatal and nonfatal injuries than their local counterparts; however, the mechanism underlying accidents and injuries in this vulnerable population has been rarely examined. This study aims to investigate relationships among safety climate, safety behavior, and safety outcomes for EM construction workers. To this end, a theoretical research model was developed based on a comprehensive review of the current literature. In total, 289 valid questionnaires were collected face-to-face from 223 Nepalese construction workers and 56 Pakistani construction workers working on 15 construction sites in Hong Kong. Structural equation modelling was employed to validate the constructs and test the hypothesized model. Results show that there were significant positive relationships between safety climate and safety behaviors, and significant negative relationships between safety behaviors and safety outcomes for EM construction workers. This research contributes to the literature regarding EM workers by providing empirical evidence of the mechanisms by which safety climate affects safety behaviors and outcomes. It also provides insights in order to help the key stakeholders formulate safety strategies for EM workers in many areas where numerous EM workers are employed, such as in the U.S., the UK, Australia, Singapore, Malaysia, and the Middle East.
We reviewed the clinical outcome of arthroscopic femoral osteochondroplasty for cam femoroacetabular impingement performed between August 2005 and March 2009 in a series of 40 patients over 60 years of age. The group comprised 26 men and 14 women with a mean age of 65 years (60 to 82). The mean follow-up was 30 months (12 to 54). The mean modified Harris hip score improved by 19.2 points (95% confidence interval 13.6 to 24.9; p < 0.001) while the mean non-arthritic hip score improved by 15.0 points (95% confidence interval 10.9 to 19.1, p < 0.001). Seven patients underwent total hip replacement after a mean interval of 12 months (6 to 24 months) at a mean age of 63 years (60 to 70). The overall level of satisfaction was high with most patients indicating that they would undergo similar surgery in the future to the contralateral hip, if indicated. No serious complications occurred. Arthroscopic femoral osteochondroplasty performed in selected patients over 60 years of age, who have hip pain and mechanical symptoms resulting from cam femoroacetabular impingement, is beneficial with a minimal risk of complications at a mean follow-up of 30 months.
Data on COPD-related healthcare resources use are rarely documented in developing countries. This article presents data on COPD-related healthcare resource consumption in the Middle East, North Africa and Pakistan and addresses the association of this variable with illness severity. A large survey of COPD was conducted in eleven countries of the region, namely Algeria, Egypt, Jordan, Lebanon, Morocco, Pakistan, Saudi-Arabia, Syria, Tunisia, Turkey and United Arab Emirates, using a standardised methodology. A total of 62,086 subjects were screened. This identified 2,187 subjects fulfilling the "epidemiological" definition of COPD. A detailed questionnaire was administered to document data on COPD-related healthcare consumption. Symptom severity was assessed using the COPD Assessment Test (CAT). 1,392 subjects were analysable. Physician consultations were the most frequently used healthcare resource, ranging from 43,118 [95% CI: 755-85,548] consultations in UAE to 4,276,800 [95% CI: 2,320,164-6,230,763] in Pakistan, followed by emergency room visits, ranging from 15,917 [95% CI: 0-34,807] visits in UAE to 683,697 [95% CI: 496,993-869,737] in Turkey and hospitalisations, ranging from 15,563 [95% CI: 7,911-23,215] in UAE to 476,674 [95% CI: 301,258-652,090] in Turkey. The use of each resource increased proportionally with the GOLD 2011 severity groups and was significantly (p < 0.0001) higher in subjects with more symptoms compared to those with lower symptoms and in subjects with exacerbations to those without exacerbations. The occurrence of exacerbations and the CAT score were independently associated with use of each healthcare resource. In conclusion, the BREATHE study revealed that physician consultation is the most frequently COPD-related healthcare resource used in the region. It showed that the deterioration of COPD symptoms and the frequency of exacerbations raised healthcare resource consumption.
COPD is a progressive pulmonary disease which may have a profound impact on general health status and quality of life. This article presents data on the burden of COPD obtained from the BREATHE study in the Middle East, North Africa and Pakistan. This study was a large general population survey of COPD conducted in eleven countries of the region using a standardised methodology. A total of 62,086 subjects were screened, of whom 2,187 fulfilled the "epidemiological" definition of COPD. Data on symptoms, perceived disease severity, impact on work, limitations in activities and psychological distress were collected. 1,392 subjects were analysable of whom 661 (47.5%) reported experiencing an exacerbation of their respiratory condition, 49.4% reported comorbidities and 5.5% reported severe breathlessness as measured with the MRC breathlessness questionnaire. The degree of breathlessness, as well as the perceived severity, was correlated with the overall disease impact as measured with the COPD Assessment Test (p < 0.001). 374 subjects (28.4%) reported that their respiratory condition prevented them from working and this proportion rose to 47.8% in subjects who perceived their respiratory condition as severe. 47.9% of subjects reported difficulties in normal physical exertion, 37.5% in social activities and 31.7% in family activities. Psychological distress was reported by between 42.3% and 53.2% of subjects, depending on the item. In conclusion, the burden of COPD is important, and covers central aspects of daily life. For this reason, physicians should take time to discuss it with their patients, and ensure that the management strategy proposed addresses all their needs.
The authors evaluated the effect of the foot on the loading axis of the lower limb measured from radiographs in 30 pediatric patients. Deviation at the knee was calculated for the hip-ankle (traditional) and the hip-foot lines (heel lined up with a metal wire). A trigonometric model of the limb loading axis was developed with predicted mechanical axis deviations at the knee. Statistics were based on the methods of Bland and Altman. Mechanical axis deviation at the knee in the frontal plane varies with foot height, foot-tibial angle, and genu valgum. The predicted trigonometric model was found to be in agreement with measured radiographic values. Including the foot in the radiographic measurement of limb alignment may increase validity of surgical planning for correction of malalignment and for evaluation of degenerative arthritis risk at the knee level.
Chronic obstructive pulmonary disease (COPD) is a potentially severe chronic progressive respiratory condition requiring long-term treatment and frequently involving episodic hospitalisations to manage exacerbations. The objective of this analysis was to document diagnosis, evaluation, treatment and management of COPD-related respiratory symptoms in 1,392 subjects fulfilling an epidemiological definition of COPD identified in a general population sample of 62,086 individuals aged ≥ 40 years in ten countries in the Middle East and North Africa region (Algeria, Egypt, Jordan, Lebanon, Morocco, Saudi Arabia, Syria, Tunisia, Turkey and United Arab Emirates), together with Pakistan. 442 subjects (31.8%) claimed to have received a diagnosis of COPD from a physician and 287 (20.6%) had undergone spirometry in the previous year. Use of specific treatments for respiratory symptoms was reported by 218 subjects (15.7%). Use of inhaled long-acting bronchodilators together with corticosteroids (53 subjects; 3.8%) and use of oxygen therapy (31 subjects; 2.3%) was very low. 852 subjects (61.2%) had consulted a physician about their respiratory condition at least once in the previous year, with a mean number of consultations of 3.4 ± 3.6. Moreover, 284 subjects (20.4%) had been hospitalised overnight for their COPD, with a mean of 2.3 ± 3.7 hospitalisations per year. Use of all healthcare resources was significantly higher (p < 0.001) in subjects with CAT scores ≥ 10 than in those with scores < 10, and greater in those with exacerbations than in those without. In conclusion, COPD in the region is under-diagnosed, inadequately evaluated and inadequately treated. Nonetheless, COPD symptoms are responsible for considerable healthcare consumption, with high levels of physician consultation and hospitalisation.
Of 460 interns from five Pakistani teaching hospitals surveyed, only 22% correctly identified the estimated number of new TB cases in Pakistan. The majority (96%) knew that droplet infection was the usual mode of transmission. Only 38% considered sputum smears for acid-fast bacilli as the best test for diagnosis of pulmonary TB and 43.5% for follow-up during TB treatment. The recommended four-drug anti-TB regimen was prescribed by 56.5% in the initiation phase and the recommended two-drug combination in the continuation phase by 52%. Most interns (82%) were unable to identify a single component of directly observed treatment short course (DOTS) strategy. Our study reflects poor awareness of and low compliance to the World Health Organization/National Tuberculosis Programme guidelines among interns. For effective control of TB, immediate action to improve undergraduate and continuing medical education is essential, with special emphasis on national guidelines.
