A randomized controlled trial: child life services in pediatric imaging.

BACKGROUND: Children undergoing procedures in pediatric health care facilities and their families have been shown to benefit from psychosocial services and interventions such as those provided by a Certified Child Life Specialist (CCLS). The comprehensive impact of a CCLS in a pediatric imaging department is well recognized anecdotally but has not been examined in a prospective or randomized controlled fashion. OBJECTIVE: We prospectively assessed the impact of a CCLS on parent satisfaction, staff satisfaction, child satisfaction, and parent and staff perceptions of child pain and distress in a pediatric imaging department. MATERIALS AND METHODS: Eligible children between 1 and 12 years of age (n = 137) presenting to the pediatric imaging department for an imaging procedure were randomly assigned to an intervention or control arm. Those assigned to the intervention received the comprehensive services of a CCLS. The control group received standard of care, which did not include any child life services. Quantitative measures of satisfaction and perception of child pain and distress were assessed by parents and staff using a written 5-point Likert scale questionnaire after the imaging procedure. Children 4 and older were asked to answer 3 questions on a 3-point scale. RESULTS: Statistically significant differences between the intervention and control groups were found in 19 out of 24 measures. Parents in the intervention group indicated higher satisfaction and a lower perception of their child's pain and distress. Staff in the intervention group indicated greater child cooperation and a lower perception of the child's pain and distress. Children in the intervention group indicated a better overall experience and less fear than those in the control group. CONCLUSION: Child life specialists have a quantifiably positive impact on the care of children in imaging departments. Measures of parent satisfaction, staff satisfaction, child satisfaction, child pain and child distress are shown to be positively impacted by the services of a CCLS. These results have significant implications for hospitals striving to increase satisfaction, decrease costs and improve quality of care. In a health care landscape that is changing quickly and increasingly focused on the cost of care, future research should assess whether the core tenants of the child life profession support and contribute quantifiably to high-quality, cost-effective practices in health care.

ESPR Uroradiology Task Force and ESUR Paediatric Working Group--Imaging recommendations in paediatric uroradiology, part V: childhood cystic kidney disease, childhood renal transplantation and contrast-enhanced ultrasonography in children.

The ESPR Uroradiology Task Force and the ESUR Paediatric Working Group present two new recommendations on imaging in childhood cystic kidney disease and in childhood renal transplantation, and address the presently restricted availability of contrast-enhanced (ce) US in children. New insights into the genetics require an updated classification of paediatric cystic kidney disease along with a new concept of diagnostic imaging. Characteristic imaging features are key to the new classification. Available recommendations for imaging renal transplantation in children are not satisfactory. The following consensus-based algorithm proposes a more effective and more uniform imaging concept, reducing invasiveness, enhancing diagnostic accuracy, and facilitating future multicentre studies and meta-analysis. At present, ce-US in children can only be performed off-license, since the only approved US contrast agent (CA) for children has been taken off the market. Nevertheless, paediatric ce-US is practiced at multiple places using Sonovue (Bracco, Milan, Italy), a generally available agent in Europe. From a medical and scientific perspective, paediatric ce-US should be promoted, and efforts are undertaken to collect data on paediatric US-CA applications. Routine paediatric imaging depends on local expertise and availability of equipment. The imaging recommendations and supportive data are intended to ease the physicians' difficult task of dealing with the specific diagnostic demands of paediatric paediatric cystic kidney disease and transplantation.

Hepatobiliary and pancreatic imaging in children-techniques and an overview of non-neoplastic disease entities.

Imaging plays a major role in the diagnostic work-up of children with hepatobiliary or pancreatic diseases. It consists mainly of US, CT and MRI, with US and MRI being the preferred imaging modalities because of the lack of ionizing radiation. In this review the technique of US, CT and MRI in children will be addressed, followed by a comprehensive overview of the imaging characteristics of several hepatobiliary and pancreatic disease entities most common in the paediatric age group.

Predictors for the selection of patients for abdominal CT after blunt trauma: a proposal for a diagnostic algorithm.

OBJECTIVE: To select parameters that can predict which patients should receive abdominal computed tomography (CT) after high-energy blunt trauma. SUMMARY BACKGROUND DATA: Abdominal CT accurately detects injuries of the abdomen, pelvis, and lumbar spine, but has important disadvantages. More evidence for an appropriate patient selection for CT is required. METHODS: A prospective observational study was performed on consecutive adult high-energy blunt trauma patients. All patients received primary and secondary surveys according to the advanced trauma life support, sonography (focused assessment with sonography for trauma [FAST]), conventional radiography (CR) of the chest, pelvis, and spine and routine abdominal CT. Parameters from prehospital information, physical examination, laboratory investigations, FAST, and CR were prospectively recorded for all patients. Independent predictors for the presence of > or =1 injuries on abdominal CT were determined using a multivariate logistic regression analysis. RESULTS: A total of 1040 patients were included, 309 had injuries on abdominal CT. Nine parameters were independent predictors for injuries on CT: abnormal CR of the pelvis (odds ratio [OR], 46.8), lumbar spine (OR, 16.2), and chest (OR, 2.37), abnormal FAST (OR, 26.7), abnormalities in physical examination of the abdomen/pelvis (OR, 2.41) or lumbar spine (OR 2.53), base excess <-3 (OR, 2.39), systolic blood pressure <90 mm Hg (OR, 3.81), and long bone fractures (OR, 1.61). The prediction model based on these predictors resulted in a R of 0.60, a sensitivity of 97%, and a specificity of 33%. A diagnostic algorithm was subsequently proposed, which could reduce CT usage with 22% as compared with a routine use. CONCLUSIONS: Based on parameters from physical examination, laboratory, FAST, and CR, we created a prediction model with a high sensitivity to select patients for abdominal CT after blunt trauma. A diagnostic algorithm was proposed.

Criteria for the selective use of chest computed tomography in blunt trauma patients.

PURPOSE: The purpose of this study was to derive parameters that predict which high-energy blunt trauma patients should undergo computed tomography (CT) for detection of chest injury. METHODS: This observational study prospectively included consecutive patients (>or=16 years old) who underwent multidetector CT of the chest after a high-energy mechanism of blunt trauma in one trauma centre. RESULTS: We included 1,047 patients (median age, 37; 70% male), of whom 508 had chest injuries identified by CT. Using logistic regression, we identified nine predictors of chest injury presence on CT (age >or=55 years, abnormal chest physical examination, altered sensorium, abnormal thoracic spine physical examination, abnormal chest conventional radiography (CR), abnormal thoracic spine CR, abnormal pelvic CR or abdominal ultrasound, base excess <-3 mmol/l and haemoglobin <6 mmol/l). Of 855 patients with >or=1 positive predictors, 484 had injury on CT (95% of all 508 patients with injury). Of all 192 patients with no positive predictor, 24 (13%) had chest injury, of whom 4 (2%) had injuries that were considered clinically relevant. CONCLUSION: Omission of CT in patients without any positive predictor could reduce imaging frequency by 18%, while most clinically relevant chest injuries remain adequately detected.

The clinical outcome of occult pulmonary contusion on multidetector-row computed tomography in blunt trauma patients.

BACKGROUND: Multidetector-row computed tomography (MDCT) is a more sensitive modality as compared with conventional radiography (CR) in detecting pulmonary injuries. MDCT often detects pulmonary contusion that is not visualized by CR, defined as occult pulmonary contusion (OPC). The aim of this study was to investigate whether OPC on MDCT has implications for the outcome in blunt trauma patients. METHODS: We used prospectively collected data from 1,040 adult high-energy blunt trauma patients who were primarily presented at our emergency department and who underwent CR and MDCT of the chest. All patients with pulmonary contusion were identified and divided into two groups: The "CR/computed tomography (CT) group" consisted of patients with pulmonary contusion visible on both CR and MDCT. The "CT-only" group consisted of patients with OPC, visible exclusively on MDCT. The control group consisted of blunt trauma patients without pulmonary contusion. These groups were compared with respect to difference in mortality and other outcome measures. In addition, a multivariate analysis was performed. RESULTS: Two hundred fifty-five patients suffered pulmonary contusion: The CT-only group consisted of 157 and the CR/CT group of 98 patients. The CT-only group did not differ from the control group with respect to mortality rate and other outcome measures. However, compared with the CR/CT group, mortality rate was significantly lower (8% versus 16%, p = 0.039) and most other outcome measures were significantly better in the CT-only group. CONCLUSION: OPC on MDCT is not associated with a worse outcome as compared with patients without pulmonary contusion. OPC has a better outcome as compared with pulmonary contusion visible on both CR and MDCT.

Routine versus selective multidetector-row computed tomography (MDCT) in blunt trauma patients: level of agreement on the influence of additional findings on management.

INTRODUCTION: This study was performed to determine the agreement between and within surgeons concerning the influence on treatment plan of routine versus selective multidetector-row computed tomography (MDCT) findings in blunt trauma patients. PATIENTS: For this study, 50 patients were randomly selected from a customized database that was originally used to compare a diagnostic algorithm with a selective use of MDCT with an algorithm with routine MDCT of the spine, chest, and abdomen within the same population. In all 50 patients, routine MDCT found additional diagnoses as compared with the selective MDCT algorithm. Of all patients, paper cases were created with detailed information on clinical parameters, findings by physical examination, and radiologic findings. The cases were independently presented to three different trauma surgeons. First, the surgeons were asked for their treatment plan based upon diagnoses found by physical examination, conventional radiography, and selective MDCT alone. Subsequently they were asked for their treatment plan with knowledge of the injuries additionally found by routine MDCT. This procedure was repeated after 3 months. The agreement between and within surgeons was determined for the change of patient management because of additional findings by routine MDCT. RESULTS: The agreement on the influence of routine MDCT findings on patient management between surgeons was moderate ([kappa] = 0.46) in the first procedure and substantial in the second ([kappa] = 0.67). The agreement within surgeons ranged from moderate ([kappa] = 0.60) to excellent ([kappa] = 0.87). CONCLUSION: All surgeons agreed that the traumatic injuries additionally found by routine MDCT, frequently resulted in a change of treatment plan. There was a moderate-to-excellent agreement between and within surgeons that these additional findings resulted in a change of treatment plan.

Routine versus selective computed tomography of the abdomen, pelvis, and lumbar spine in blunt trauma: a prospective evaluation.

BACKGROUND: Discussion still remains whether computed tomography (CT) of the abdomen, pelvis, and lumbar spine should be performed routinely after blunt trauma with high energy impact or only in restricted situations. The purpose of this study was to evaluate the additional value of a routine CT algorithm as compared with a more restricted, selective CT algorithm. MATERIALS: This prospective study consisted of 465 patients that met the inclusion criteria of our high-energy trauma protocol. All patients underwent physical examination, abdominal ultrasound (AUS), and conventional radiography (CR) of the pelvis and lumbar spine and subsequently routine CT of the abdomen, pelvis, and lumbar spine. Before CT, a subgroup of patients with abnormal physical examination or CR or AUS was prospectively defined as the selective CT group. Type and extent of injuries and impact on treatment were recorded for both the routine CT group and the selective CT subgroup. RESULTS: Of all patients, 42 received selective CT of the abdomen, 71 of the pelvis, and 48 of the lumbar spine. Compared with the algorithm with selective CT, routine CT revealed additional traumatic injuries in 15% of the patients in the abdomen, in 2.4% in the pelvis and in 8.2% in the lumbar spine. This resulted in an overall change of treatment in 6.4% (95% confidence interval, 3.7-9.0) of the patients who would not have received CT in a selective CT algorithm. CONCLUSIONS: Compared with an algorithm with selective CT, an algorithm with routine CT finds substantially more clinically relevant diagnoses, even in patients with unsuspicious clinical examination, normal CR, and normal AUS.

MRI compared to conventional diagnostic work-up in the detection and evaluation of invasive lobular carcinoma of the breast: a review of existing literature.

PURPOSE: The clinical diagnosis and management of invasive lobular carcinoma (ILC) of the breast presents difficulties. Magnetic resonance imaging (MRI) has been proposed as the imaging modality of choice for the evaluation of ILC. Small studies addressing different aspects of MRI in ILC have been presented but no large series to date. To address the usefulness of MRI in the work-up of ILC, we performed a review of the currently published literature. MATERIALS AND METHODS: We performed a literature search using the query "lobular AND (MRI OR MR OR MRT OR magnetic)" in the Cochrane library, PubMed and scholar.google.com, to retrieve all articles that dealt with the use of MRI in patients with ILC. We addressed sensitivity, morphologic appearance, correlation with pathology, detection of additional lesions, and impact of MRI on surgery as different endpoints. Whenever possible we performed meta-analysis of the pooled data. RESULTS: Sensitivity is 93.3% and equal to overall sensitivity of MRI for malignancy in the breast. Morphologic appearance is highly heterogeneous and probably heavily influenced by interreader variability. Correlation with pathology ranges from 0.81 to 0.97; overestimation of lesion size occurs but is rare. In 32% of patients, additional ipsilateral lesions are detected and in 7% contralateral lesions are only detected by MRI. Consequently, MRI induces change in surgical management in 28.3% of cases. CONCLUSION: This analysis indicates MRI to be valuable in the work-up of ILC. It provides additional knowledge that cannot be obtained by conventional imaging modalities which can be helpful in patient treatment.

Arm raising at exposure-controlled multidetector trauma CT of thoracoabdominal region: higher image quality, lower radiation dose.

PURPOSE: To evaluate the effect of arm position on image quality and effective radiation dose in an automatic exposure-controlled (AEC) multidetector thoracoabdominal computed tomography (CT) protocol in trauma patients. MATERIALS AND METHODS: This retrospective study of the data of 177 trauma patients (117 male; median age, 39 years) was approved by the institutional ethics board, with informed patient consent waived. Patients underwent scanning by using an AEC 16-detector thoracoabdominal CT protocol in which both arms were raised above the shoulder region (standard-position group, 132 patients), one arm was raised and the other was down (one-arm group, 27 patients), or both arms were down (two-arm group, 18 patients). Objective and subjective image quality was assessed. Individual effective radiation dose was calculated from the effective tube current-time product per exposed section. For this purpose, section location-dependent conversion factors were derived by using a CT dosimetry calculator. The effect of arm position on effective dose was quantified by using linear regression analysis with correction for patient volume and attenuation. RESULTS: Compared with the image quality in the standard-position group, the image quality in the one- and two-arm groups was decreased but within acceptable diagnostic limits. The median corrected effective dose in the standard-position group was 18.6 mSv; the dose in the one-arm group was 18% (95% confidence interval: 11%, 25%) higher than this, and that in the two-arm group was 45% (95% confidence interval: 34%, 57%) higher. CONCLUSION: Omitting arm raising results in lower but acceptable image quality and a substantially higher effective radiation dose. Hence, effort should be made to position the arms above the shoulder when scanning trauma patients. Clinical trial registration no. NCT00228111.

Added value of routine chest MDCT after blunt trauma: evaluation of additional findings and impact on patient management.

OBJECTIVE: The objective of our study was to evaluate the added value of a low-threshold routine thoracic MDCT algorithm compared with a selective MDCT algorithm in adult blunt trauma patients. SUBJECTS AND METHODS: A prospective cohort study was conducted in 464 consecutive blunt trauma patients who met criteria indicative of severe blunt trauma (66% male; age range, 16-93 years; median injury severity score, 13). After clinical evaluation and conventional radiography of the chest and thoracic spine, all patients underwent routine thoracic MDCT with an IV contrast agent (routine MDCT algorithm). Within this routine MDCT group, a subgroup was prospectively defined with abnormal or inconclusive clinical or conventional radiography evaluation (selective MDCT group). Two investigators determined the type, extent, and clinical impact of additional injuries found on MDCT as compared to conventional radiography for both MDCT groups. RESULTS: Of all 464 patients within the routine MDCT group, 164 patients underwent selective MDCT, which resulted in detection of additional diagnoses compared with conventional radiography in 97 (59%) patients. The routine MDCT algorithm detected additional diagnoses compared with conventional radiography in 201 of 464 patients (43%). Compared with the selective MDCT algorithm, this was an absolute increase of 104 of 464 (22%) extra patients, resulting in a change in patient management in 34 (7%; 95% CI, 5-9.7%), mostly because of additional findings of pulmonary and mediastinal injury. CONCLUSION: Routine MDCT has relatively lower, though still substantial, added diagnostic value compared with selective MDCT of the chest.

Mechanical birth-related trauma to the neonate: An imaging perspective.

Mechanical birth-related injuries to the neonate are declining in incidence with advances in prenatal diagnosis and care. These injuries, however, continue to represent an important source of morbidity and mortality in the affected patient population. In the United States, these injuries are estimated to occur among 2.6% of births. Although more usual in context of existing feto-maternal risk factors, their occurrence can be unpredictable. While often superficial and temporary, functional and cosmetic sequelae, disability or even death can result as a consequence of birth-related injuries. The Agency for Healthcare research and quality (AHRQ) in the USA has developed, through expert consensus, patient safety indicators which include seven types of birth-related injuries including subdural and intracerebral hemorrhage, epicranial subaponeurotic hemorrhage, skeletal injuries, injuries to spine and spinal cord, peripheral and cranial nerve injuries and other types of specified and non-specified birth trauma. Understandably, birth-related injuries are a source of great concern for the parents and clinician. Many of these injuries have imaging manifestations. This article seeks to familiarize the reader with the clinical spectrum, significance and multimodality imaging appearances of neonatal multi-organ birth-related trauma and its sequelae, where applicable. Teaching points • Mechanical trauma related to birth usually occurs with pre-existing feto-maternal risk factors.• Several organ systems can be affected; neurologic, musculoskeletal or visceral injuries can occur.• Injuries can be mild and transient or disabling, even life-threatening.• Imaging plays an important role in injury identification and triage of affected neonates.

Prevalence of testicular adrenal rest tumours in male children with congenital adrenal hyperplasia due to 21-hydroxylase deficiency.

OBJECTIVE: Testicular adrenal rest tumours (TART) are a well-known complication in adult male patients with congenital adrenal hyperplasia (CAH), with a reported prevalence of up to 94%. In adulthood, the tumours are associated with gonadal dysfunction most probably due to longstanding obstruction of the seminiferous tubules. The aim of our study was to determine the presence of TART and their influence on gonadal function in childhood. DESIGN: Retrospective study. PATIENTS AND METHODS: Scrotal ultrasound was performed in 34 children with CAH due to 21-hydroxylase deficiency who were between 2 and 18 years old. FSH, LH, testosterone and inhibin B concentrations were measured in serum of 27 patients. RESULTS: TART were detected by ultrasound in 8 out of 34 (24%) children. In two of them, bilateral tumours were found. All lesions were located in the rete testis. Seven patients had the salt-wasting type of CAH; one patient had the simple virilising type of CAH. Mean tumour size was 4.1 mm (range 2-8 mm). In none of the patients were the tumours palpable. Two children with TART were between 5 and 10 years old, the other six children were above 10 years old. In all children with TART, LH, FSH, testosterone and inhibin B levels were similar to the patients without TART. CONCLUSION: TART can be found in CAH children before the age of 10 years. The absence of gonadal dysfunction in our group of children suggests that gonadal dysfunction as frequently reported in adult CAH patients with TART develops after childhood.

Ultrasound of the rotator cuff with MRI and anatomic correlation.

Magnetic resonance imaging and high-resolution ultrasound (US) are frequently used for the detection of rotator cuff tears. The diagnostic yield of US is influenced by several factors as technique, knowledge of the imaging characteristics of anatomic and pathologic findings and of pitfalls. The purpose of this article is to illustrates that the standardized high-resolution US examination of the shoulder covers the entire rotator cuff and correlates with MR imaging and anatomic sections.

Pervasive access to images and data--the use of computing grids and mobile/wireless devices across healthcare enterprises.

Emerging technologies are transforming the workflows in healthcare enterprises. Computing grids and handheld mobile/wireless devices are providing clinicians with enterprise-wide access to all patient data and analysis tools on a pervasive basis. In this paper, emerging technologies are presented that provide computing grids and streaming-based access to image and data management functions, and system architectures that enable pervasive computing on a cost-effective basis. Finally, the implications of such technologies are investigated regarding the positive impacts on clinical workflows.

Imaging of Posttraumatic Arthritis, Avascular Necrosis, Septic Arthritis, Complex Regional Pain Syndrome, and Cancer Mimicking Arthritis.

This article focuses on the imaging of 5 discrete entities with a common end result of disability: posttraumatic arthritis, a common form of secondary osteoarthritis that results from a prior insult to the joint; avascular necrosis, a disease of impaired osseous blood flow, leading to cellular death and subsequent osseous collapse; septic arthritis, an infectious process leading to destructive changes within the joint; complex regional pain syndrome, a chronic limb-confined painful condition arising after injury; and cases of cancer mimicking arthritis, in which the initial findings seem to represent arthritis, despite a more insidious cause.

From the RSNA refresher courses: US of the rotator cuff: pitfalls, limitations, and artifacts.

High-resolution ultrasonography (US) has gained increasing popularity as a diagnostic tool for assessment of the soft tissues in shoulder impingement syndrome. US is a powerful and accurate method for diagnosis of rotator cuff tears and other rotator cuff abnormalities, provided the examiner has a detailed knowledge of shoulder anatomy, uses a standardized examination technique, and has a thorough understanding of the potential pitfalls, limitations, and artifacts. False-positive sonographic findings of rotator cuff tears can be caused by the technique (anisotropy, transducer positioning, acoustic shadowing by the deltoid septum), by the anatomy (rotator cuff interval, supraspinatus-infraspinatus interface, musculotendinous junction, fibrocartilaginous insertion), or by disease (criteria for diagnosis of rotator cuff tears, tendon inhomogeneity, acoustic shadowing by scar tissue or calcification, rotator cuff thinning). False-negative sonographic findings of rotator cuff tears can be caused by the technique (transducer frequency, suboptimal focusing, imaging protocol, transducer handling), by the anatomy (nondiastasis of the ruptured tendon fibers, posttraumatic obscuration of landmarks), by disease (tendinosis, calcifications, synovial proliferation, granulation or scar tissue, bursal thickening, massive rotator cuff tears), or by patient factors (obesity, muscularity, limited shoulder motion).

Genotype-phenotype studies in nail-patella syndrome show that LMX1B mutation location is involved in the risk of developing nephropathy.

Nail-patella syndrome (NPS) is characterized by developmental defects of dorsal limb structures, nephropathy, and glaucoma and is caused by heterozygous mutations in the LIM homeodomain transcription factor LMX1B. In order to identify possible genotype-phenotype correlations, we performed LMX1B mutation analysis and comprehensive investigations of limb, renal, ocular, and audiological characteristics in 106 subjects from 32 NPS families. Remarkable phenotypic variability at the individual, intrafamilial, and interfamilial level was observed for different NPS manifestations. Quantitative urinanalysis revealed proteinuria in 21.3% of individuals. Microalbuminuria was detected in 21.7% of subjects without overt proteinuria. Interestingly, nephropathy appeared significantly more frequent in females. A significant association was established between the presence of clinically relevant renal involvement in an NPS patient and a positive family history of nephropathy. We identified normal-tension glaucoma (NTG) and sensorineural hearing impairment as new symptoms associated with NPS. Sequencing of LMX1B revealed 18 different mutations, including six novel variants, in 28 families. Individuals with an LMX1B mutation located in the homeodomain showed significantly more frequent and higher values of proteinuria compared to subjects carrying mutations in the LIM domains. No clear genotype-phenotype association was apparent for extrarenal manifestations. This is the first study indicating that family history of nephropathy and mutation location might be important in precipitating individual risks for developing NPS renal disease. We suggest that the NPS phenotype is broader than previously described and that NTG and hearing impairment are part of NPS. Further studies on modifier factors are needed to understand the mechanisms underlying phenotypic heterogeneity.

Magnetic resonance-guided biopsies and localizations of the breast: initial experiences using an open breast coil and compatible intervention device.

OBJECTIVE: The objective of this study was to evaluate the performance of a new commercially available open breast coil and compatible intervention device (Machnet) for magnetic resonance image (MRI)-guided breast interventions. MATERIALS AND METHODS: Breast lesions detected on MRI were evaluated using MRI-guided core biopsy (n = 20) and/or preoperative wire localization (n = 23) on histologic outcome and accuracy of localization. Time needed to perform a procedure and occurring problems were recorded. RESULTS: Mean lesion size was <10 mm. Two of 20 lesions could not be biopsied because they were out of range for the device. Biopsies were conclusive in half of the cases; most lesions missed were <10 mm. The average accuracy for needle placement in the localization procedures was less than 2 mm (range, 0-5 mm). The average procedure time was 40 minutes for a biopsy procedure and 33 minutes for an MRI-guided localization. CONCLUSIONS: Preoperative MRI-guided localizations can be performed quickly and accurately. However, in MRI-guided core biopsies, especially in small lesions, the device does not guarantee conclusive histologic evaluation of the lesion targeted.

A three-center, randomized, controlled trial of individualized developmental care for very low birth weight preterm infants: medical, neurodevelopmental, parenting, and caregiving effects.

Medical, neurodevelopmental, and parenting effects of individualized developmental care were investigated in a three-center, randomized, controlled trial. A total of 92 preterm infants, weighing less than 1250 g and aged less than 28 weeks, participated. Outcome measures included medical, neurodevelopmental and family function. Quality of care was also assessed. Multivariate analysis of variance investigated group, site, and interaction effects; correlation analysis identified individual variable contributions to significant effects. The results consistently favored the experimental groups. The following contributed to the group effects: shorter duration of parenteral feeding, transition to full oral feeding, intensive care, and hospitalization; lower incidence of necrotizing enterocolitis; reduced discharge ages and hospital charges; improved weight, length, and head circumferences; enhanced autonomic, motor, state, attention, and self-regulatory functioning; reduced need for facilitation; and lowered family stress and enhanced appreciation of the infant. Quality of care was measurably improved. Very low birth weight infants and their parents, across diverse settings, may benefit from individualized developmental care.
