ABSTRACT

This retrospective study assessed the effectiveness and impact of implementing a Modified Early Warning System (MEWS) and Rapid Response Team (RRT) for inpatients admitted to the general ward (GW) of a medical center. This study included all inpatients who stayed in GWs from Jan. 2017 to Feb. 2022. We divided inpatients into GWnon-MEWS and GWMEWS groups according to MEWS and RRT implementation in Aug. 2019. The primary outcome, unexpected deterioration, was defined by unplanned admission to intensive care units. We defined the detection performance and effectiveness of MEWS according to if a warning occurred within 24 h before the unplanned ICU admission. There were 129,039 inpatients included in this study, comprising 58,106 GWnon-MEWS and 71,023 GWMEWS. The numbers of inpatients who underwent an unplanned ICU admission in GWnon-MEWS and GWMEWS were 488 (.84%) and 468 (.66%), respectively, indicating that the implementation significantly reduced unexpected deterioration (p < .0001). Besides, 1,551,525 times MEWS assessments were executed for the GWMEWS. The sensitivity, specificity, positive predicted value, and negative predicted value of the MEWS were 29.9%, 98.7%, 7.09%, and 99.76%, respectively. A total of 1,568 warning signs accurately occurred within the 24 h before an unplanned ICU admission. Among them, 428 (27.3%) met the criteria for automatically calling RRT, and 1,140 signs necessitated the nursing staff to decide if they needed to call RRT. Implementing MEWS and RRT increases nursing staff's monitoring and interventions and reduces unplanned ICU admissions.

ABSTRACT

Chronic kidney disease (CKD) is a multifactorial, complex condition that requires proper management to slow its progression. In Thailand, 11.6 million people (17.5%) have CKD, with 5.7 million (8.6%) in the advanced stages and >100,000 requiring hemodialysis (2020 report). This study aimed to develop a risk prediction model for CKD in Thailand. Data from 17,100 patients were collected to screen for 14 independent variables selected as risk factors, using the IBK, Random Tree, Decision Table, J48, and Random Forest models to train the predictive models. In addition, we address the unbalanced category issue using the synthetic minority oversampling technique (SMOTE). The indicators of performance include classification accuracy, sensitivity, specificity, and precision. This study achieved an accuracy rate of 92.1% with the top-performing Random Forest model. Moreover, our empirical findings substantiate previous research through highlighting the significance of serum albumin, blood urea nitrogen, age, direct bilirubin, and glucose. Furthermore, this study used the SHapley Additive exPlanations approach to analyze the attributes of the top six critical factors and then extended the comparison to include dual-attribute factors. Finally, our proposed machine learning technique can be used to evaluate the effectiveness of these risk factors and assist in the development of future personalized treatment.

ABSTRACT

Background/purpose: Life expectancy (LE) is a hypothetical measure to predict life longevity and the indicator of society's overall health. Tooth loss is a worldwide enigma; however, the LE for tooth (LET) are obscure. LET and the burden of tooth loss in Taiwan were estimated using the scheme of National Health Insurance (NHI). Materials and methods: Using NHI data, mortality rate, age-specific mortality rate, tooth-extraction rate, and age-specific tooth-extraction rate (ASTER) of Taiwanese in 2004 and 2013 were estimated. ASTER for the individual tooth (ASTER-T) was analyzed for each of 28 permanent teeth according to ID code and tooth location. LET and years lived with disability for tooth loss (YLDs-T) of each permanent tooth were estimated following Global Burden Disease study. Results: In 2004, 1,741,228 teeth extracted from 1,078,254 patients among 22,646,835 Taiwanese, whereas 2,012,907 teeth extracted from 1,254,746 patients among 23,344,670 in 2013. In both years, the ASTERs presented an increasing trend as age increased. However, the ASTER-Ts presented varied according to tooth types. The LET and YLDs-T were also varied. The maximum values of YLDs-T were noticed for the first molars. Conclusion: Our findings of this national survey highlight the need for public health policy, particular the early loss of first molars, aiming to increase awareness regarding oral health.

ABSTRACT

Methamphetamine abuse is getting worse amongst the younger population. While there is methadone or buprenorphine harm-reduction treatment for heroin addicts, there is no drug treatment for addicts with methamphetamine use disorder (MUD). Recently, non-medication treatment, such as the cue-elicited craving method integrated with biofeedback, has been widely used. Further, virtual reality (VR) is proposed to simulate an immersive virtual environment for cue-elicited craving in therapy. In this study, we developed a VR system equipped with flavor simulation for the purpose of inducing cravings for MUD patients in therapy. The VR system was integrated with multi-model sensors, such as an electrocardiogram (ECG), galvanic skin response (GSR) and eye tracking to measure various physiological responses from MUD patients in the virtual environment. The goal of the study was to validate the effectiveness of the proposed VR system in inducing the craving of MUD patients via the physiological data. Clinical trials were performed with 20 MUD patients and 11 healthy subjects. VR stimulation was applied to each subject and the physiological data was measured at the time of pre-VR stimulation and post-VR stimulation. A variety of features were extracted from the raw data of heart rate variability (HRV), GSR and eye tracking. The results of statistical analysis found that quite a few features of HRV, GSR and eye tracking had significant differences between pre-VR stimulation and post-VR stimulation in MUD patients but not in healthy subjects. Also, the data of post-VR stimulation showed a significant difference between MUD patients and healthy subjects. Correlation analysis was made and several features between HRV and GSR were found to be correlated. Further, several machine learning methods were applied and showed that the classification accuracy between MUD and healthy subjects at post-VR stimulation attained to 89.8%. In conclusion, the proposed VR system was validated to effectively induce the drug craving in MUD patients.

ABSTRACT

BACKGROUND: Little is known about the characteristics of patients needing palliative care consultation in the emergency department (ED). This study aimed to investigate the impacts of initiating screening in acute critically ill patients needing palliative care on mortality, health care resources, and end-of-life (EOL) care in the intensive care unit in ED (EICU). METHODS: We conducted an analysis study in Taipei Veterans General Hospital. From February 1 to July 31, 2018, acute critically ill patients in EICU were recruited. The primary outcomes were inhospital mortality and EOL care. The secondary outcomes included clinical characteristics and health care utilization. RESULTS: A total of 796 patients were screened, with 396 eligible and 400 noneligible patients needing palliative care consultations. The mean age was 74.8 ± 17.1 years, and 62.6% of the patients were male. According to logistic regression analysis, clinical predictors, including age (adjusted odds ratio [AOR], 1.028; 95% CI, 1.015-1.042), respiratory distress and/or respiratory failure (AOR, 2.670; 95% CI, 1.829-3.897), the Acute Physiology and Chronic Health Evaluation II score (AOR, 1.036; 95% CI, 1.009-1.064), Charlson Comorbidity Index score (AOR, 1.212; 95% CI, 1.125-1.306), and Glasgow Coma Scale (AOR, 0.843; 95% CI, 0.802-0.885), were statistically more significant in eligible patients than in noneligible patients. The inhospital mortality rate was significantly higher in eligible patients than that in noneligible patients (40.7% vs 11.5%, p < 0.01). Eligible patients have a higher ratio in both vasopressor and narcotic use and withdrawal of endotracheal tube than noneligible patients (p < 0.05). CONCLUSION: Our study results demonstrated that initiating palliative consultation for acute critically ill patients in ED had an impact on the utilization of health care resources and quality of EOL care. Further assessments of the viewpoints of ED patients and their family on palliative care consultations and hospice care are required.

ABSTRACT

RATIONALE: Anxiety is a mediator for emotional reactivity and acute blood pressure elevations, which are associated with an increased risk of cardiovascular death. Alprazolam is a common medication for anxiolysis. We hypothesized that alprazolam usage can reduce the risk of major adverse cardiovascular events (MACEs) in patients with hypertension. METHODS: A retrospective cohort study was performed using datasets from Taiwanese Health and Welfare Data. Patients with hypertension were divided into exposed (Alprazolam-exposed) and control groups (non-Alprazolam-exposed) with 1:1 propensity score matching. The study endpoint was the occurrence of MACE. Adjusted hazard ratio (aHR) of MACE risk was estimated using the multiple Cox proportional hazard model. Age-stratified analysis was performed to evaluate the interaction of age and alprazolam use with MACEs. RESULTS: The study cohort consisted of 335 517 alprazolam-exposed patients and 1:1 PSM controls. The mean age was 63.62 ± 12.71 years in the Alprazolam-exposed population. Alprazolam exposure was significantly associated with reduced risk of MACEs (aHR = 0.965, 95% CI = 0.954-0.977), including ischemic stroke (aHR = 0.958, 95% CI = 0.940-0.976), hemorrhagic stroke (aHR = 0.856, 95% CI = 0.821-0.892), myocardial infarction (aHR = 0.933, 95% CI = 0.900-0.968), sudden cardiac death (aHR = 0.955, 95% CI = 0.916-0.996), and all-cause mortality (aHR = 0.921, 95% CI = 0.909-0.932). In the age-subgroup analysis, alprazolam showed the greatest risk reduction effect in hemorrhagic stroke for patients aged <65 years (aHR = 0.779, 95% CI = 0.727-0.835). CONCLUSION: Alprazolam usage in patients with hypertension was associated with a slightly reduced risk of MACEs and all-cause mortality, and up to 22% reduced risk of hemorrhagic stroke was observed in alprazolam users aged <65 years.

ABSTRACT

BACKGROUND: Hip hemiarthroplasty (HHA) is a common treatment for hip fractures in the elderly population. Because of the fatal effects of bone cement implantation syndrome, the safety of cement utilization to enhance implant firmness in the femur is controversial. The aim of this study was to investigate the postoperative survival of elderly patients receiving HHA with and without cement fixation. METHODS: Claim data from the National Health Insurance Database and the National Register of Deaths Database were used for analysis in this retrospective cohort study. From 2008 to 2014, 25,862 patients aged 80 years or older treated with hip hemiarthroplasty were included in the analysis. A Cox proportional risk model was used to analyse the effects of cement utilization on postoperative mortality. RESULTS: The cemented group had a significantly higher mortality risk than the non-cemented group within 7, 30, 180 days and 1 year after the operation. The effect of bone cement on postoperative mortality was significantly stronger within 7 days than within 30, 180 days and 1 year. In addition, the male gender, age > 85 years and higher score on the Charlson Comorbidity Index were also risk factors for mortality (p < 0.05). Patients who received HHA in lower-volume hospitals had higher mortality rates within 180 days and 1 year than those in higher-volume hospitals. Compared with patients who were operated on by high-volume surgeons, those who received surgery performed by lower-volume surgeons were more likely to die within 30 days (aHR = 1.22), 180 days (aHR = 1.16) and 1 year (aHR = 1.19), respectively. CONCLUSIONS: The postoperative mortality rate of elderly patients undergoing HHA was significantly higher in the cemented group than in the non-cemented group.

ABSTRACT

Emergency department crowding has been one of the main issues in the health system in Taiwan. Previous studies have usually targeted the process improvement of patient treatment flow due to the difficulty of collecting Emergency Department (ED) staff data. In this study, we have proposed a hybrid model with Discrete Event Simulation, radio frequency identification applications, and activity-relationship diagrams to simulate the nurse movement flows and identify the relationship between different treatment sections. We used the results to formulate four facility layouts. Through comparing four scenarios, the simulation results indicated that 2.2 km of traveling distance or 140 min of traveling time reduction per nurse could be achieved from the best scenario.

ABSTRACT

Patients with chronic mental illness are highly vulnerable to chronic respiratory problems. We examined the influence of mental disability on respiratory infection-related utilization risk in individuals with and without mental disabilities. A population-based, retrospective cohort design and two-part model were used to analyze respiratory infection-related utilization in individuals with MDs (MD group) and a matched reference group. The respiratory infection-related utilization rate in one year was lower in the MD group (53.8%) than in the reference group (56.6%). The odds ratios (ORs) were significantly higher among individuals with profound MDs (aOR = 1.10; 95% CI 1.07-1.14) and those with a history of dental cavities (aOR = 1.16; 95% CI: 1.13-1.19) or periodontal disease (aOR = 1.22; 95% CI: 1.19-1.26) after controlling for covariables. The average number of visits was higher in the MD group (5.3) than in the reference group (4.0). The respiratory infection-related utilization rate and average number of visits were significantly higher in the mild, moderate and severe disabled groups with a history of periodontal disease, respectively, than that of the reference group. In conclusion, healthcare authorities must develop an incentive program to prevent respiratory infections among individuals with MDs.

ABSTRACT

OBJECTIVE: A test battery that measures cognitive function impairment in patients with schizophrenia, the Brief Assessment of Cognition in Schizophrenia (BACS), has been translated into various languages and validated. This study aimed to test the reliability and validity of the Chinese version of the BACS in a Chinese-speaking population. METHODS: All participants in this study (66 patients with schizophrenia [mean age: 41.2 years, 57.6% male] and 66 age- and sex-matched healthy controls) were from Taiwan and assessed using the BACS and the University of California, San Diego (UCSD) Performance-Based Skills Assessment, Brief Version (UPSA-B). Thirty-eight of the 66 patients with schizophrenia received a reassessment using the BACS. RESULTS: The BACS had good test-retest reliability, and all BACS subtests had statistically insignificant practice effects. Principal components analysis demonstrated that a one-factor solution best fits our dataset (60.9% of the variance). In both patients and controls, the BACS composite scores were positively correlated with all BACS subscales (P<0.001) and UPSA-B scales (P<0.001). Furthermore, all BACS subtests (verbal memory, working memory, motor speed, verbal fluency, attention and processing speed, and executive function) significantly differentiated patients with schizophrenia from healthy controls (P<0.001), and the BACS composite score had the best discriminative validity (P<0.001). CONCLUSION: The Chinese version of the BACS exhibits satisfactory psychometric properties, including high test-retest reliability, high internal consistency, acceptable concurrent validity, and good discriminant validity. We suggest that the BACS is a reliable and practical tool for assessing cognitive function in patients with schizophrenia.

ABSTRACT

There is a distinct lack of knowledge on the prevalence of skin disorders in Tuvalu. The aim of the current study was to assess the prevalence of cutaneous diseases and to evaluate access dermatological care in Tuvalu. Cutaneous disorders in the people of Tuvalu between 2009 and 2012 were examined. The most common skin conditions were eczema/dermatitis, superficial fungal infections, impetigo, carbuncles, furuncles, folliculitis, acne, scabies, warts and keloids. Infrequent skin conditions included infectious granulomatous disease, albinism, actinic keratosis, skin cancer, cutaneous lupus erythematosus and mammary Paget's disease, which required medical attention. This is the first epidemiological report on skin disorders in the southwest Pacific Island, Tuvalu.

ABSTRACT

BACKGROUND: Several medical conditions that mimic ST-elevation myocardial infarction (STEMI) have been reported previously, but acute abdominal disease mimicking STEMI is rare. CASE REPORT: We report on a 72-year-old man who presented to the emergency department (ED) with epigastric pain. Meanwhile, STEMI with shock developed. Anticoagulation medication and emergent percutaneous coronary intervention (PCI) were arranged in a timely manner. However, hepatocellular carcinoma (HCC) rupture was the true cause of the ST-segment elevation. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: This case report highlights the fact that acute myocardial infarction is not the only cause of ST-segment elevation. HCC rupture should be one of the differential diagnoses.

ABSTRACT

Traumatic brain injury (TBI) causes increased release of several mediators from injured and dead cells and elicits microglial activation. Activated microglia change their morphology, migrate to injury sites, and release tumor necrosis factor-alpha (TNF-α) and others. In this study we used a controlled fluid percussion injury model of TBI in the rat to determine whether early (4 h post-injury) or late (4 days post-injury) treatment with MLC 601, a Traditional Chinese Medicine, would affect microglial activation and improve recovery. MLC 601 was chosen for this study because its herbal component MLC 901 was beneficial in treating TBI in rats. Herein, rats with induced TBI were treated with MLC 601 (0.2-0.8 mg/kg) 1 h (early treatment) or 4 day post-injury (late treatment) and then injected once daily for consecutive 2 days. Acute neurological and motor deficits were assessed in all rats the day before and 4 days after early MLC 601 treatment. An immunofluorescence microscopy method was used to count the numbers of the cells colocalized with neuron- and apoptosis-specific markers, and the cells colocalized with microglia- and TNF-α-specific markers, in the contused brain regions 4 days post-injury. An immunohistochemistry method was used to evaluate both the number and the morphological transformation of microglia in the injured areas. It was found that early treatment with MLC 601 had better effects in reducing TBI-induced cerebral contusion than did the late therapy with MLC 601. Cerebral contusion caused by TBI was associated with neurological motor deficits, brain apoptosis, and activated microglia (e.g., microgliosis, amoeboid microglia, and microglial overexpression of TNF-α), which all were significantly attenuated by MLC 601 therapy. Our data suggest that MLC 601 is a promising agent for treatment of TBI in rats.

ABSTRACT

OBJECTIVES: This nationwide cohort study investigated the association between proton pump inhibitor (PPI) usage and the risk of pneumonia in patients with non-traumatic intracranial haemorrhage (ICH). DESIGN: Nationwide population-based cohort study. SETTING: Longitudinal Health Insurance Database 2010 (LHID2010) sampled from the Taiwan National Health Insurance Research Database. PARTICIPANTS: 4644 patients with non-traumatic ICH from 2010 to 2011 were identified. Patients aged <18 years and newly diagnosed with non-traumatic ICH complicated with pneumonia during the same admission period were excluded. A total of 2170 participants were eligible for the final analysis. MAIN OUTCOME MEASURE: Patients using PPIs or not during the study period were tracked to identify the occurrence of any type of pneumonia. RESULTS: The adjusted HR of the risk of pneumonia for ICH patients who used PPIs was 1.61 (95% CI 1.32 to 1.97, p<0.001). The risk of pneumonia was positively associated with the administration of PPIs. We observed a greater risk of pneumonia in patients who used PPIs than in those who did not. Moreover, we observed that the risk of pneumonia in patients who used PPIs was 2.60 and 2.04 (95% CI 2.01 to 3.38, p<0.001; 95% CI 1.34 to 3.10, p<0.001) greater than that in patients who did not use PPIs when the defined daily dose was <30 and 30-60, respectively. CONCLUSIONS: The results of this study indicate that the use of PPIs in patients with non-traumatic ICH is associated with an increased risk of pneumonia, and the severity of this risk depends on the defined daily dose. Physicians should exercise caution when prescribing PPIs for patients with non-traumatic ICH.

ABSTRACT

BACKGROUND: The primary goal of this study was to test whether high-altitude exposure (HAE of 9.7% O2 at 0.47 absolute atmosphere [ATA] for 3 days) was capable of increasing lung edema, neutrophil, and hemorrhage scores as well as decreasing lung levels of both aquaporin 1 (AQP1) and AQP5 proteins and messenger RNA (mRNA) expression in rats, with a secondary goal to test whether a preinduction of heat shock protein 70 (HSP70) by hyperbaric oxygen preconditioning (HBO2P of 100% O2 at 2.0 ATA for 1 hour per day for 5 consecutive days) attenuated the HAE-induced increased lung injury scores and decreased lung AQP1 and AQP5 protein and mRNA expressions. METHODS: Rats were assigned to (1) non-HBO2P (21% O2 at 1.0 ATA) + non-HAE (21% O2 at 1.0 ATA) group; (2) non-HBO2P + HAE group; (3) HBO2P + HAE group; and HBO2P + HSP70 antibodies (Ab) + HAE group. For the HSP70 Ab group, a neutralizing HSP70 Ab was injected intravenously at 24 hours before HAE. All the physiologic and biochemical parameters were obtained at the end of HAE or the equivalent period of non-HAE. The cardiovascular and blood gas parameters were monitored for all experiments. Bronchoalveolar lavage (BAL) was performed to determine proinflammatory cytokines (interleukin 6, interleukin 1ß, and tumor necrosis factor α). Parts of the lung were excised for myeloperoxidase activity measurement, whereas the rest was collected for lung damage score assessments. AQP1 and AQP5 protein and mRAN expressions were also determined in the lung tissues. RESULTS: In the non-HBO2P + HAE group, the animals displayed higher values of lung myeloperoxidase activity, BAL proinflammatory cytokines, lung water weight, and acute lung injury scores compared with those of the non-HBO2P + non-HAE controls. In contrast, the non-HBO2P + HAE group rats had lower values of lung AQP1 and AQP5 protein and mRNA expressions, mean arterial pressure, heart rate, SO2, Paco2, HCO3, and pH compared with those of non-HBO2P + non-HAE group rats. The increased acute lung edema, neutrophil, and hemorrhage scores; increased BAL levels of proinflammatory cytokines; decreased lung AQP1 and AQP5 protein and mRNA expressions; and hypotension, bradycardia, hypoxia, and acidosis caused by HAE were all significantly attenuated by HBO2P. CONCLUSION: Our data indicate that HBO2P may attenuate high-altitude acute lung injury by a preinduction of lung HSP70 in rats.

ABSTRACT

BACKGROUND: Because out-of-hospital cardiac arrests (OHCAs) due to a major trauma rarely present with shockable rhythms, the potential benefits of using automated external defibrillators (AEDs) at the scene of traumatic OHCAs have not been examined. METHODS: We conducted an observational, retrospective cohort study using an Utstein-style analysis in Tainan city, Taiwan. The enrollees were adult patients with traumatic OHCAs accessed by emergency medical technicians (EMTs) from January 1, 2004 to December 31, 2010. The exposure was the use or non-use of AEDs at the scene, as determined by the clinical judgment of the EMTs. The primary outcome evaluated was a sustained (≥2h) return of spontaneous circulation (ROSC), and the secondary outcomes were prehospital ROSC, overall ROSC, survival to hospital admission, survival at one month and favorable neurologic status at one month. RESULTS: A total of 424 patients (313 males) were enrolled, of whom 280 had AEDs applied, and 144 did not. Only 25 (5.9%) patients had received bystander cardiopulmonary resuscitation (CPR), and merely 21 (7.5%) patients in the AED group presented with shockable rhythms. Compared to the non-AED group, the primary and secondary outcomes of the AED group were not significantly different, except for a significantly lower prehospital ROSC rate (1.1% vs. 4.9%, p<0.05). Multivariate analysis showed no significant interactions between the use of AEDs and other key variables. Use of the AED was not associated with sustained ROSC (OR 1.33; 95% CI 0.75-2.38, p=0.33). CONCLUSIONS: In a community with a low prevalence of shockable rhythms and administration of bystander CPR in patients with traumatic OHCA, we found no significant differences in the sustained ROSC between the AED and the non-AED groups. Considering scene safety and the possible interruption of CPR, we do not encourage the routine use of AEDs at the scene of traumatic OHCAs.

ABSTRACT

BACKGROUND/PURPOSE: An intubating laryngeal mask airway (ILMA) is an alternative device for airway control, capable of providing effective ventilation in various situations. The purpose of this study is to compare the effects of the ILMA and bag-valve-mask (BVM) ventilation devices on out-of-hospital cardiac arrest (OHCA) patients. METHODS: An ILMA training course was conducted by emergency medical technicians (EMTs). Before training, OHCA patients had received BVM ventilation; these patients were defined as the BVM group. After training, all EMTs in the area being served were instructed to immediately use an ILMA on OHCA patients when possible; these patients were defined as the ILMA group. Demographics, transport time, first arterial blood gas data, and the short-term outcomes of these two groups were analyzed. RESULTS: A total of 398 OHCA patients (89 in the BVM group and 309 in the ILMA group) were analyzed. All of the EMTs passed the training course, and ILMAs were used in the emergency settings. The ILMA was applied to each OHCA patient for a longer-than-average field time than the BVM (9.5 vs. 7.8 minutes, p = 0.006). The 24-hour survival rate of the ILMA-treated patients was significantly higher than BVM-treated patients (36.2% vs. 24.7%, p = 0.033). CONCLUSION: Well-trained EMTs were able to insert the ILMA and ventilate OHCA patients properly in prehospital settings, and ILMA-treated OHCA patients had better short-term outcomes than BVM-treated patients.

ABSTRACT

With a collectivist cultural perspective, we examined the positive effects of employees' perceptions of a familial climate on loyalty to supervisors, the mediation of loyalty between perception of a familial climate and job performance, and the moderation of employees' filial behaviour on the relationship between perception of a familial climate and loyalty. The participants consisted of 247 supervisor-and-subordinate dyads in Taiwan. The results supported our hypotheses. Through the mechanisms of family behaviour transference, social identification and supervisor-subordinate exchange, perception of an organizational familial climate enhanced loyalty to supervisors. Furthermore, loyalty to supervisors mediated the relationship between perception of a familial climate and job performance. Filial behaviour moderated the relationship between perception of a familial climate and loyalty; thus, the relationship of perception of a familial climate and loyalty was stronger for employees with low levels of filial behaviour and weaker for employees with high levels of filial behaviour. These findings are discussed in terms of their theoretical and practical implications for future research and management practices.
