Carbapenem susceptibility among Escherichia coli, Klebsiella pneumoniae, and Enterobacter cloacae isolates obtained from patients in intensive care units in Taiwan in 2005, 2007, and 2009

To investigate the evolutionary trends in non-susceptibility of carbapenems against the isolates of Escherichia coli, Klebsiella pneumoniae, and Enterobacter cloacae from patients hospitalized in intensive care units (ICUs) of major teaching hospitals throughout Taiwan during 2005–2009, we applied the breakpoints of MICs recommended by Clinical and Laboratory Standards Institute and European Committee on Antimicrobial Susceptibility Testing in 2013. Escalations in imipenem MIC levels for overall E. coli and E. cloacae isolates and extended-spectrum β-lactamase (ESBL)–producing K. pneumoniae isolates were noted during this period. The overall MIC levels against imipenem and meropenem for subgroups of ESBL producers of 3 Enterobacteriaceae species were significantly higher than those of respective overall groups in 2007 and 2009. Compared with meropenem, we found that significant evidence of imipenem MIC creep and evidence of extraordinarily high rates of non-susceptibility to ertapenem among isolates of 3 species in 2009 existed. The prominent rises in rates of ertapenem non-susceptibility for ESBL-producing E. coli and K. pneumoniae during 2005–2009 and rate of ESBL positivity for E. cloacae between 4years were notably found. Based on our findings, ertapenem should be used cautiously in management of the ICU infections caused by these potentially ESBL-producing Enterobacteriaceae isolates in Taiwan.

The Negative Impact of Early Peritonitis on Continuous Ambulatory Peritoneal Dialysis Patients

Peritonitis rate has been reported to be associated with technique failure and overall mortality in previous literatures. However, information on the impact of the timing of the first peritonitis episode on continuous ambulatory peritoneal dialysis (CAPD) patients is sparse. The aim of this research is to study the influence of time to first peritonitis on clinical outcomes, including technique failure, patient mortality and dropout from peritoneal dialysis (PD). A retrospective observational cohort study was conducted over 10 years at a single PD unit in Taiwan. A total of 124 patients on CAPD with at least one peritonitis episode comprised the study subjects, which were dichotomized by the median of time to first peritonitis into either early peritonitis patients or late peritonitis patients. Cox proportional hazard model was used to analyze the correlation of the timing of first peritonitis with clinical outcomes. Early peritonitis patients were older, more diabetic and had lower serum levels of creatinine than the late peritonitis patients. Early peritonitis patients were associated with worse technique survival, patient survival and stay on PD than late peritonitis patients, as indicated by Kaplan-Meier analysis (log-rank test, p = 0.04, p < 0.001, p < 0.001, respectively). In the multivariate Cox regression model, early peritonitis was still a significant predictor for technique failure (hazard ratio (HR), 0.54; 95% confidence interval (CI), 0.30 - 0.98), patient mortality (HR, 0.34; 95% CI, 0.13 - 0.92) and dropout from PD (HR, 0.50; 95% CI, 0.30 - 0.82). In continuous analyses, a 1-month increase in the time to the first peritonitis episode was associated with a 2% decreased risk of technique failure (HR, 0.98; 95% CI, 0.97 - 0.99), a 3% decreased risk of patient mortality (HR, 0.97; 95% CI, 0.95 - 0.99), and a 2% decreased risk of dropout from PD (HR, 98%; 95% CI, 0.97 - 0.99). Peritonitis rate was inversely correlated with time to first peritonitis according to the Spearman analysis (r = -0.64, p < 0.001). Time to first peritonitis is significantly correlated with clinical outcomes of peritonitis patients with early peritonitis patients having poor prognosis. Patients with shorter time to first peritonitis were prone to having a higher peritonitis rate.

Wishes of Patients With Terminal Cancer and Influencing Factors Toward the Use of Antibiotics in Taiwan.

The use of antibiotics is a common ethical dilemma in palliative care, thus identifying the concerns of patients with terminal cancer and respecting their wishes are important in making an ethically justified decision. The aim of this study was to understand wishes of patients with terminal cancer and determine influencing factors toward the use of antibiotics. Two hundred and one patients with terminal cancer, admitted to a palliative care unit in Taiwan, completed a structured questionnaire interview, including demographic characteristics, knowledge and attitudes on antibiotics, the health locus of control, subjective norms, and the wishes to use antibiotics. The most common misconception was "Antibiotics use is helpful to all terminal patients with infection," which only 13.4% respondents disagreed. Of the 201patients, 92 (45.8%) expressed their wishes to use antibiotics even in the very terminal stage, and around one-fourth (26.4%) of patients wished not to use antibiotics, the remaining 27.8% were unclear. The most influential persons were medical professionals. The results of logistic regression analysis that showed familiarity with antibiotics, subjective norms, and the attitude toward burdens of antibiotics were the most significant predicting variables for those wishing to use antibiotics (odds ratio [OR] = 4.133, 95% confidence interval [CI] = 1.012-16.880; OR = 1.890, 95% CI = 1.077-3.317; and OR = 1.255, 95% CI = 1.047-1.503). This study indicated the responsibility of medical professionals to convey burdens of using antibiotics to patients and family. Otherwise, by enhancing professional training and performing effective communication with patients, we can reach a more appropriate decision in the use of antibiotics.

Prevalence and Molecular Characterization of Staphylococcus aureus Colonization among Neonatal Intensive Care Units in Taiwan

Background:Staphylococcus aureus, particularly methicillin-resistant (MRSA), is an important pathogen in neonatal intensive care units (NICUs). Carriage of S. aureus is a significant risk factor for subsequent infection. Objectives: To determine the current status of MRSA prevalence among NICU-hospitalized infants in Taiwan, we conducted this pilot island-wide survey. Methods: On two designated dates in 2011, each patient who stayed in the NICUs of 7 participating hospitals was included. Nasal and umbilical swabs were obtained and sent for detection of S. aureus. The prevalence and risk factors for MRSA carriage were analyzed. MRSA strains were tested for antimicrobial susceptibility and underwent molecular characterization. Results: A total of 251 subjects were included. The overall prevalence of S. aureus and MRSA carriage was 13 and 4.4%, respectively. Previous skin and soft tissue infection was the only predictor in multivariate analysis (OR 40.36; 95% CI 2.32-702.64; p = 0.011). Among 11 MRSA isolates, 3 pulsotypes were identified, with one major type (73%). Nine isolates carried a type IV staphylococcal chromosomal cassette, and 2 carried the type V_T. All but one MRSA isolate belonged to linage sequence type 59, the community clone in Taiwan. Conclusions: On a designated date, 4.4% of the infants staying in NICUs in Taiwan carried almost genetically identical community strains of MRSA. MRSA colonization in these infants was significantly associated with previous skin and soft tissue infection.

Taiwanese Parents' Experience of Making a “Do Not Resuscitate” Decision for Their Child in Pediatric Intensive Care Unit

The purpose of this project was to explore the parental experience of making a "do not resuscitate" (DNR) decision for their child who is or was cared for in a pediatric intensive care unit in Taiwan. A descriptive qualitative study was conducted following parental signing of a standard hospital DNR form on behalf of their critically ill child. Sixteen Taiwanese parents of 11 children aged 1 month to 18 years were interviewed. Interviews were recorded, transcribed, analyzed and sorted into themes by the sole interviewer plus other researchers. Three major themes were identified: (a) "convincing points to sign", (b) "feelings immediately after signing", and (c) "post-signing relief or regret". Feelings following signing the DNR form were mixed and included "frustration", "guilt", and "conflicting hope". Parents adjusted their attitudes to thoughts such as "I have done my best," and "the child's life is beyond my control." Some parents whose child had died before the time of the interview expressed among other things "regret not having enough time to be with and talk to my child". Open family visiting hours plus staff sensitivity and communication skills training are needed. To help parents with this difficult signing process, nurses and other professionals in the pediatric intensive care unit need education on initiating the conversation, guiding the parents in expressing their fears, and providing continuing support to parents and children throughout the child's end of life process.

Is It Appropriate To Withdraw Antibiotics in Terminal Patients with Cancer with Infection?

Antibiotic administration is frequent in terminal patients with cancer, yet the effects on survival are still under debate. The aim of this study was to examine the status of infection and the benefit/burden of antibiotic administration on the survival of terminal patients with cancer with infection. A prospective observational study. We studied 799 patients with terminal cancer who were admitted to a palliative care unit in Taiwan between January 2008 and the end of April 2010. Survival was calculated from the first day of admission to the day of death in the palliative care unit or under home care. A specially designed assessment tool was used daily to evaluate clinical conditions. Afterwards, it was analyzed at different time points in a weekly team meeting. Multivariate Cox proportional hazard analyses were used to examine the benefit/burden of antibiotic administration on survival. Four hundred fifty-five patients were diagnosed as having at least one episode of infection after first admission. A total of 295 of the 378 (78.0%) with infection received antibiotic treatment upon admission. Multivariate Cox proportional hazard analyses showed that antibiotic administration was related to improved survival for patients who were still alive 1 week after admission (hazard ratio: 0.66, 95% confidence interfal [CI]: 0.46-0.95). However, antibiotics would be a hazard to patients' survival if used in the time 2 days prior to death (hazard ratio: 1.54, 95% CI: 1.22-1.94). The results suggest that with good communication between patients, families, and medical staff, withdrawal of antibiotics should be considered if signs of death appear, in order to avoid unnecessary risks. The possible benefit of prolonged survival should be in line with the goal of care, and also take into account preparing the patient for a dignified death.

A population-based analysis of children with pneumonia among intensive care units in Taiwan

Pneumonia is a major diagnosis in children that requires intensive care and is a major cause of mortality in critically ill children. A survey on current epidemiology and case fatality-associated conditions is crucial for the care of critically ill children with pneumonia in an intensive care unit (ICU). The sex, age, seasonality of admission, area of distribution, and case fatality rate of children younger than 18 years who had pneumonia and were admitted to an ICU during the period 2006-2010 were obtained from the National Health Insurance Research Database (NHIRD) of Taiwan. The enrolled children were grouped by age (0-2 years, 3-5 years, 6-11 years, and 12-17 years). The need for invasive procedures such as endotracheal tube (ET) insertion, mechanical ventilation (MV), tracheostomy, central venous catheter (CVC) insertion, chest tube insertion/drainage, chest surgery, and extracorporeal membranous oxygenation (ECMO) were analyzed to clarify their association with case fatality in critically ill children with pneumonia. Of the 12,577 children enrolled, 7131 (56.7%) were boys and 5446 (43.3%) were girls. The younger age groups had more cases of pneumonia, but less often required invasive procedures. Children 0-2 years old (n = 6083) accounted for approximately one-half (48.4%) of all enrolled children. This group had the lowest case fatality rate (3.1%; 187/6083 children) and lowest need for invasive procedures (31.1%; 1892/6083 children), whereas children in the 12-17 year-old group had the highest case fatality rate (9.9%; 140/1417 children) and the highest need for invasive procedures (59.8%; 847/1417 children) (p < 0.001). The percentage of pneumonia cases was highest in the spring (30.1%) and lowest in the summer (21.7%). The invasive procedures associated with case fatality were ET/MV (OR, 14.31; p < 0.001), CVC insertion (OR, 7.46; p < 0.001), ECMO intervention (OR, 4.59; p < 0.001), and chest tube insertion/drainage (OR, 1.87; p < 0.001). The number of cases of pneumonia that required ICU admission was greater among younger children than among older children. Factors associated with the higher case fatality rate included older age at presentation, the need for invasive procedures (e.g., ET/MV, CVC insertion, chest tube insertion/drainage, and ECMO), underlying comorbidities and complications.

Demographic Factors Influencing Consensus Opinion on the Recall for Women Screened by Mobile Mammography Unit in Taiwan

BackgroundThe incidence of breast cancer has had a four-fold increase from 1980 to 2005 in Taiwan. Limited data have been available on mobile breast screening in the Taiwanese population since 2009.ObjectivesThis study aims at investigating the factors influencing consensus opinion on the recall for mobile breast screening in Taiwan.Patients and MethodsThe factors were categorized by individual health background, socioeconomic status and knowledge about breast screening. There were 502 questionnaires collected from Taiwanese women examined on mobile mammography screening vehicle. Data were then analyzed by SPSS 12 via analysis of variance (ANOVA), F-test, t-test or chi-square test.ResultsStrong participation was associated with a younger age, higher educational level, higher incomes, previous history of cancer, previous family history of cancer, one or two prior mammographies, more correct recognitions of mammography, recall rate, and breast cancer risk. If the false-positive result occurred, 83.9%, 81.9% and 77.3% of the women agreed or strongly agreed to participate in noninvasive and invasive testing and screening mammography, respectively.ConclusionThe policy makers should notify the importance of demographic factors affecting further examination for early detection of breast cancer in Taiwan.

Relationship between the distribution of cefepime minimum inhibitory concentrations and detection of extended-spectrum β-lactamase production among clinically important Enterobacteriaceae isolates obtained from patients in intensive care units in Taiwan: Results from the Surveillance of Multicenter Antimicrobial Resistance in Taiwan (SMART) in 2007

The data on susceptibility of important cephalosporins against four Enterobacteriaceae members producing potential extended-spectrum β-lactamase (ESBL) collected from Taiwanese intensive care units are lacking. Minimum inhibitory concentrations (MICs) of cefotaxime, ceftazidime, and cefepime were determined using agar dilution method, against Escherichia coli (n = 344), Klebsiella pneumoniae (n = 359), Enterobacter cloacae (n = 103), and Proteus mirabilis (n = 78). Susceptibilities of these isolates to three cephalosporins were assessed according to MIC breakpoints recommended by the Clinical and Laboratory Standards Institute (CLSI) and the European Committee on Antimicrobial Susceptibility Testing (EUCAST) in 2013. The double-disk synergy test using disks containing cefepime (30 μg) with or without clavulanate (10 μg) was applied to confirm production of ESBL for isolates with cephalosporin MIC ≥ 2 μg/mL. A total of 175 isolates were verified as ESBL producers. The rates of cefepime susceptibility among the ESBL-producing isolates, according to CLSI (EUCAST) criteria, were 56.7% (22.4%) for E. coli, 61.3% (12.0%) for K. pneumoniae, 57.9% (31.6%) for E. cloacae, and 71.4% (7.1%) for P. mirabilis. Using different cefepime MIC breakpoints (MICs ≥ 16 μg/mL recommended by CLSI criteria and ≥ 2 μg/mL by EUCAST criteria) to define nonsusceptibility, we found that both criteria were poorer at predicting ESBL producers among K. pneumoniae and E. cloacae than among the other two species. In addition, we also found that the cefepime MIC level of 1.0 μg/mL best distinguished non-ESBL- from ESBL-producing K. pneumoniae and E. cloacae. To detect ESBLs, CLSI should revise the cefepime MIC breakpoint against Enterobacteriaceae.

Effects of Quality Assurance Regulatory Enforcement on Performance of Mammography Systems: Evidence From Large-Scale Surveys in Taiwan

The Standards for Medical Exposure Quality Assurance in mammography systems were enacted on July 1, 2008, in Taiwan. This study aimed to evaluate the trends in performance of mammography units before and after the regulation started on the basis of annual on-site surveys from 2008 to 2010. On-site measurements were conducted on 215, 205, and 209 mammography units in 2008, 2009, and 2010, respectively, which accounted for more than 95% of all units in Taiwan. Phantom image quality, average glandular dose (AGD), and half-value layer were evaluated on all systems. Processor conditions, compression conditions, radiation output, and computed radiography exposure indicators were assessed on units participating in mammography screening in 2008 and on all units in the later years. Evaluations of maximum compression force and automatic exposure control reproducibility were added into the protocol from 2009 onward. Mean phantom scores were improved significantly from 2008 to 2009 (11.63 ± 1.30 vs 12.31 ± 0.94, p < 0.05) and remained stable for 2010 (12.35 ± 0.87). Mean AGDs were 1.48 ± 0.47, 1.38 ± 0.41, and 1.37 ± 0.42 mGy over the 3 years, with a significant reduction from 2008 to 2009 (p < 0.05). For film-screen mammography systems, variations of sensitometric curves were greatly reduced in 2009 and 2010 when compared with 2008. Passing rates were increased after the regulation took effect in almost all aspects. Results from large-scale on-site surveys showed an overall improvement in performance after quality assurance in mammography was enforced in Taiwan.

SU‐E‐I‐59: Patient‐Based Average Glandular Dose Estimations in Taiwan

Purpose: The objective of the study was to investigate the average glandular dose (AGD) distributions based on the patients with average‐sized breasts in Taiwan. Methods: Patient data were collected from 199 mammography units of 167 facilities (76% of the units in Taiwan) during 2012 in Taiwan. For each unit, exposure parameters including target/filter, kVp and tube loadings of 15 patients with average‐compressed breast size of 4.2±0.5 cm in craniocaudal (CC) views were recorded by the technologists. Half value layer (HVL) and radiation exposure per mAs were measured at specific beam quality during the annual on‐site inspection. Entrance skin exposure for each patient was thus estimated based on the radiation output data, patient exposure techniques and compressed breast thickness. Both the conversion factors calculated by Dance and Wu were used for further AGD calculations for comparisons. Average of the AGDs of the 15 patients may served as the represented mean AGD for each mammographic unit, and dose distributions could also be obtained for further evaluations. Results: Based on the conversion factors calculated by Dance, AGDs ranged from 95.8 to 505.7 mrad, and the mean, median and 3rd quartile of the estimated AGD of the 199 mammographic units was 191.9 mrad, 172.2 mrad, and 228.0 mrad, respectively. By calculating AGDs using Wu's conversion factors, AGDs ranged from 73.3 to 390.4 mrad, and the mean, median and 3rd quartile of the estimated AGD of the 199 mammographic units was 156.1 mrad, 143.5 mrad, and 186.2 mrad, respectively. Estimated AGDs using Wu's correction factors got the lower AGD values compared to the AGDs estimated by Dance method. Conclusion: AGD distributions based on nationwide represented patient data may serve as a baseline dose database for future diagnostic reference level (DRL) establishment in mammography in Taiwan. This work was supported by grants from Atomic Energy Council of Taiwan(AEC10101003L).

Predicting clinical instability of older patients in post‐acute care units: A nationwide cohort study

Although patients admitted to post-acute care (PAC) units are usually clinically stable, unexpected medical conditions requiring acute ward readmissions still occur and can jeopardize the clinical effectiveness of PAC services. The main purpose of the present study was to evaluate predictive factors for clinical instability of patients in PAC units to improve the quality of PAC services. This was a nationwide multicenter cohort study that recruited patients from five PAC units in Taiwan between July 2007 and June 2009. All patients received the comprehensive geriatric assessment (CGA) within 72 h of PAC unit admissions. Conditions requiring acute ward re-admissions from PAC units were defined as clinical instability. Causes of clinical instability for all patients and data of CGA were collected for analysis. Of 918 enrolled participants, 119 (12.9%) experienced acute ward readmissions, including 106 (89.1%) admissions related to medical conditions and 13 (10.9%) for surgical causes. Common conditions included diseases of the respiratory system (n = 32, 26.9%), genitourinary system (n = 24, 20.2%) and digestive system (n = 14, 11.8%). Surgical conditions, mainly fractures and dislocation of upper limbs, were significantly more likely to occur later (P = 0.05) in the PAC unit admissions than medical conditions. Compared with the non-readmission group, the readmission group was leaner (mean body mass index 21.1 ± 2.8 vs 22.0 ± 3.8 kg/m(2) , P = 0.007), having poorer functional status (mean Barthel Index 41.0 ± 19.4 vs 45.4 ± 20.3, P = 0.02; mean IADL: 1.3 ± 1.6 vs 1.7 ± 1.8, P = 0.016), poorer cognitive function (mean Mini-Mental State Examination: 16.8 ± 6.4 vs 18.3 ± 6.4, P = 0.022), poorer ambulation (mean Timed Up & Go test 32.7 ± 18.7 vs 26.6 ± 11.7 s, P = 0.039) and poorer nutritional status (mean Mini-Nutrition Assessment 13.3 ± 5.7 vs 15.4 ± 5.8, P < 0.001), but similar in depression status (mean Geriatric Depression Score 3.7 ± 3.3 vs 3.4 ± 2.8, P = 0.247). In multivariate logistical regression model, lower Mini-Mental State Examination score was the only independent predictor for clinical instability (odds ratio 3.8, 95% confidence interval 1.348-10.870, P = 0.012). Approximately 13% of PAC patients might experience acute ward readmissions, and nearly 90% of them are caused by medical conditions. Poor cognitive function is a significant predictive factor for clinical instability in PAC, which deserves more clinical attention for all PAC patients.

Carbapenem susceptibilities and non-susceptibility concordance to different carbapenems amongst clinically important Gram-negative bacteria isolated from intensive care units in Taiwan: Results from the Surveillance of Multicentre Antimicrobial Resistance in Taiwan (SMART) in 2009

To investigate the in vitro susceptibilities to various carbapenems amongst clinical Gram-negative bacteria isolated from patients in intensive care units of ten major teaching hospitals in Taiwan in 2009, a survey was conducted to determine the minimum inhibitory concentrations (MICs) of ertapenem, imipenem, meropenem and doripenem against isolates of Enterobacteriaceae (n=594), Pseudomonas aeruginosa (n=185), Acinetobacter baumannii (n=192) and Burkholderia cepacia (n=23) using the agar dilution method. Susceptibilities were determined according to 2009, 2011 and 2012 MIC breakpoints recommended by the CLSI as well as 2012 MIC breakpoints recommended by EUCAST. Based on CLSI 2012 criteria, the ertapenem susceptible rate was 93%, 81%, 68% and 92% for Escherichia coli, Klebsiella pneumoniae, Enterobacter cloacae and Serratia marcescens, respectively. All Proteus mirabilis and Morganella morganii isolates were susceptible to ertapenem; however, 64% of P. mirabilis and all M. morganii isolates were non-susceptible to imipenem. Meropenem and doripenem had better activities than imipenem against ertapenem-non-susceptible Enterobacteriaceae isolates. E. coli, K. pneumoniae and E. cloacae with ertapenem MICs≥4mg/L were synchronously not susceptible to imipenem, meropenem and doripenem. Imipenem susceptibility was 65% and 29% for P. aeruginosa and A. baumannii, respectively. Additionally, P. aeruginosa and A. baumannii isolates with imipenem MICs≥8mg/L were also not susceptible to meropenem and doripenem. These data provide a better understanding of choosing appropriate carbapenem agents to treat infections caused by ertapenem-non-susceptible Enterobacteriaceae as well as P. aeruginosa and A. baumannii isolates with imipenem MICs≥4mg/L.

Health issues among nurses in Taiwanese hospitals: National survey

BackgroundFew, if any, studies have compared the health issues of nurses working in different hospital settings. The objective of this study was to compare the health status and work-related health hazards among nurses working in different hospital units in Taiwan. MethodsThis study was a cross-sectional survey. The study participants were 21,095 full-time employees with a professional background in nursing, working at 100 hospitals across Taiwan. The study participants responded to a structured questionnaire from May to July, 2011. ResultsAfter adjustment for age, sex, educational level, accredited hospital level, and certification as a health promoting hospital, nurses who worked in administration and in outpatient clinics reported better overall health than nurses who worked in operating rooms/delivery rooms, and these nurses reported better overall health than nurses who worked in emergency rooms/intensive care units and general wards. Depressed mood followed the same trend. Nurses who worked in the operating rooms/delivery rooms, wards, and emergency rooms/intensive care units were at higher risk for occupational incidents than nurses who worked in outpatient clinics and administration. The most prevalent health hazards among nurses were low back pain, sprained/strained muscles, cuts, and verbal or sexual harassment/violence. ConclusionsNurses who worked in emergency rooms/intensive care units and in wards had worse health and more depressed moods than nurses in other hospital units. Work-related health hazards were common and varied among nurses working in different hospital units. Worksite-based health promotion programs should take these differences into consideration to tailor wellness programs for nurses working in different hospital settings.

Exposure to di(2-ethylhexyl) phthalate in premature neonates in a neonatal intensive care unit in Taiwan

Neonates are exposed to high levels of di(2ethylhexyl) phthalate through numerous medical procedures in the neonatal intensive care unit. Our aim was to assess the contribution of specific medical devices to the di(2-ethylhexyl) phthalate exposure of neonates. Prospective. University hospital. We recruited 32 premature neonates, 20 with very low birth weight (<1500 g) and 12 with low birth weight (<2500 g), and 31 controls at a neonatal intensive care unit from a medical center in central Taiwan. Interventions were based on a clinical need and used standard materials and devices, including endotracheal tubes, continuous positive airway pressure, oxygen hood, intravenous injection, intralipid injection, blood transfusion, orogastric tubes, nasogastric tubes, umbilical venous catheterization, umbilical arterial catheterization, chest tube, and isolate. We recorded the medical procedures of each subject, collected their urine samples, and determined the urinary concentration of three metabolites of di(2-ethylhexyl) phthalate using reversed-phase high-performance liquid chromatography-atmospheric pressure chemical ionization-tandem mass spectrometry. Median levels of di(2-ethylhexyl) phthalate metabolites in premature neonates treated with an endotracheal tube and orogastric tube or nasogastric tube were significantly higher than those not treated with an endotracheal tube, orogastric tube, or nasogastric tube. Median levels of di(2-ethylhexyl) phthalate metabolites in premature neonates treated with intravenous injection were ≥ 2-fold higher than those of healthy controls who received intravenous injections (p = .01). Median levels of three di(2-ethylhexyl) phthalate metabolites were similar in very-low-birth-weight and low-birth-weight neonates. These data suggest that polyvinyl chloride-containing devices are the major defining factor in di(2-ethylhexyl) phthalate exposure levels in neonates in the neonatal intensive care unit. We urge the use of polyvinyl chloride-free or alternative materials in medical devices, especially for endotracheal tubes, orogastric tubes, nasogastric tubes, and intravenous tubing in the neonatal intensive care unit. The health effects of high di(2-ethylhexyl) phthalate exposure on premature neonates in the neonatal intensive care unit is worthy of further investigation.

Preterm infants' biobehavioral responses to caregiving and positioning over 24 hours in a neonatal unit in Taiwan

This prospective, descriptive study used a repeated-measures design to explore preterm infants' biobehavioral responses to 24-hour neonatal caregiving and positioning, and the factors associated with changes in their biobehavioral responses. Thirty preterm infants (gestational age 27.6-36.1 weeks) were observed for 3 days to record biobehavioral responses. Infants' disorganized behaviors increased as caregiving intrusiveness and supine positioning increased. Social interactions did not lead to increases in infants' disorganized behaviors, but to increased regulatory behaviors. Non-nutritive sucking (NNS), and prone positioning reduced occurrences of infant disorganized behaviors. Routine caregiving increased instability of oxygen saturation, but lateral and prone positioning improved physiological stability. Clinicians can appropriately provide NNS, positioning, and social interactions to promote biobehavioral stability.
