Development of a Definition of Postacute Sequelae of SARS-CoV-2 Infection.

Importance: SARS-CoV-2 infection is associated with persistent, relapsing, or new symptoms or other health effects occurring after acute infection, termed postacute sequelae of SARS-CoV-2 infection (PASC), also known as long COVID. Characterizing PASC requires analysis of prospectively and uniformly collected data from diverse uninfected and infected individuals. Objective: To develop a definition of PASC using self-reported symptoms and describe PASC frequencies across cohorts, vaccination status, and number of infections. Design, Setting, and Participants: Prospective observational cohort study of adults with and without SARS-CoV-2 infection at 85 enrolling sites (hospitals, health centers, community organizations) located in 33 states plus Washington, DC, and Puerto Rico. Participants who were enrolled in the RECOVER adult cohort before April 10, 2023, completed a symptom survey 6 months or more after acute symptom onset or test date. Selection included population-based, volunteer, and convenience sampling. Exposure: SARS-CoV-2 infection. Main Outcomes and Measures: PASC and 44 participant-reported symptoms (with severity thresholds). Results: A total of 9764 participants (89% SARS-CoV-2 infected; 71% female; 16% Hispanic/Latino; 15% non-Hispanic Black; median age, 47 years [IQR, 35-60]) met selection criteria. Adjusted odds ratios were 1.5 or greater (infected vs uninfected participants) for 37 symptoms. Symptoms contributing to PASC score included postexertional malaise, fatigue, brain fog, dizziness, gastrointestinal symptoms, palpitations, changes in sexual desire or capacity, loss of or change in smell or taste, thirst, chronic cough, chest pain, and abnormal movements. Among 2231 participants first infected on or after December 1, 2021, and enrolled within 30 days of infection, 224 (10% [95% CI, 8.8%-11%]) were PASC positive at 6 months. Conclusions and Relevance: A definition of PASC was developed based on symptoms in a prospective cohort study. As a first step to providing a framework for other investigations, iterative refinement that further incorporates other clinical features is needed to support actionable definitions of PASC.

Prevalence of SARS-CoV-2 antibodies in pediatric healthcare workers.

OBJECTIVES: To determine SARS-CoV-2-antibody prevalence in pediatric healthcare workers (pHCWs). DESIGN: Baseline prevalence of anti-SARS-CoV-2-IgG was assessed in a prospective cohort study from a large pediatric healthcare facility. Prior SARS-CoV-2 testing history, potential risk factors and anxiety level about COVID-19 were determined. Prevalence difference between emergency department (ED)-based and non-ED-pHCWs was modeled controlling for those covariates. Chi-square test-for-trend was used to examine prevalence by month of enrollment. RESULTS: Most of 642 pHCWs enrolled were 31-40years, female and had no comorbidities. Half had children in their home, 49% had traveled, 42% reported an illness since January, 31% had a known COVID-19 exposure, and 8% had SARS-CoV-2 PCR testing. High COVID-19 pandemic anxiety was reported by 71%. Anti-SARS-CoV-2-IgG prevalence was 4.1%; 8.4% among ED versus 2.0% among non-ED pHCWs (p < 0.001). ED-work location and known COVID-19 exposure were independent risk factors. 31% of antibody-positive pHCWs reported no symptoms. Prevalence significantly (p < 0.001) increased from 3.0% in April-June to 12.7% in July-August. CONCLUSIONS: Anti-SARS-CoV-2-IgG prevalence was low in pHCWs but increased rapidly over time. Both working in the ED and exposure to a COVID-19-positive contact were associated with antibody-seropositivity. Ongoing universal PPE utilization is essential. These data may guide vaccination policies to protect front-line workers.

Short term outcomes of an enhanced recovery after surgery (ERAS) pathway versus a traditional discharge pathway after posterior spinal fusion for adolescent idiopathic scoliosis.

PURPOSE: Enhanced Recovery after Surgery (ERAS) pathways have been shown to decrease length of stay (LOS) after posterior spinal fusion (PSF) for adolescent idiopathic scoliosis (AIS). The aim of this study was to compare immediate post-operative outcomes following an ERAS pathway with a traditional pathway for AIS. METHODS: A prospective dual-center study of patients treated using an ERAS pathway (203 patients) or a traditional discharge (TD) pathway (73 patients) was performed with focus on pain at discharge, quality of life at one month, and return to school/work. RESULTS: LOS was 55% less in the ERAS group (4.8 days TD vs. 2.2 days ERAS, p < 0.001). Length of surgery (4.8 h TD vs. 2.8 h, p < 0.001) and EBL (500 cc vs. 240 cc, p < 0.001) were greater in the TD group, likely related to larger curve magnitudes ((62.0° TD vs. 54.0° ERAS, p < 0.001), a higher percentage of patients undergoing osteotomies (94% vs. 46%, p < 0.001) and more levels fused (11.4 ± 1.6 vs. 10.1 ± 2.6, p < 0.001) in the TD group. Regression analysis showed no difference in Visual Analog Score (VAS) score at discharge or quality of recovery using the QOR9 instrument between groups at follow up. There was no difference in return to school (p = 0.43) and parents' return to work (p = 0.61) between the groups. CONCLUSION: Patients managed with an ERAS pathway had similar pain scores at discharge than those managed with a TD pathway. Both groups showed evidence of rapid return to normalcy by the first follow up visit.

Effect of a Dedicated Orthopaedic Advanced Practice Provider in a Level I Trauma Center: Analysis of Length of Stay and Cost.

OBJECTIVES: The objective of this study is to analyze the effect of an orthopaedic trauma advanced practice provider on length of stay (LOS) and cost in a level I trauma center. The hypothesis of this study is that the addition of a single full-time nurse practitioner (NP) to the orthopaedic trauma team at a level I Trauma center would decrease overall LOS and hospital cost. METHODS: A retrospective chart review of all patients discharged from the orthopaedic surgery service 1 year before the addition of a NP (pre-NP) and 1 year after the hiring of a NP (post-NP) were reviewed. Chart review included age, gender, LOS, discharge destination, intravenous antibiotic use, wound VAC therapy, admission location, and length of time to surgery. Statistical analysis was performed using the Wilcoxon/Kruskal-Wallis test. RESULTS: The hiring of a NP yielded a statistically significant decrease in the LOS across the following patient subgroups: patients transferred from the trauma service (13.56 compared with 7.02 days, P < 0.001), patients aged 60 years and older (7.34 compared with 5.04 days, P = 0.037), patients discharged to a rehabilitation facility (10.84 compared with 8.31 days, P = 0.002), and patients discharged on antibiotics/wound VAC therapy (15.16 compared with 11.24 days, P = 0.017). Length of time to surgery was also decreased (1.48 compared with 1.31 days, P = 0.37). CONCLUSIONS: The addition of a dedicated orthopaedic trauma advanced practice provider at a county level I trauma center resulted in a statistically significant decrease in LOS and thus reduced indirect costs to the hospital. LEVEL OF EVIDENCE: Economic Level IV. See Instructions for Authors for a complete description of levels of evidence.

Volar ligament release and distal radial dome osteotomy for the correction of Madelung deformity: long-term follow-up.

BACKGROUND: Madelung deformity is a disorder of growth of the distal aspect of the radius that is usually recognized in late adolescence near skeletal maturity. It results in a characteristic wrist deformity, decreased wrist motion, and wrist pain. The purpose of this study was to evaluate long-term results in patients treated by volar ligament release and distal radial dome osteotomy for Madelung deformity. METHODS: Patients who had undergone volar ligament release and dome osteotomy for Madelung deformity at our institution from 1990 to 2002 and who were the subjects of a previous report on this treatment were contacted for clinical and radiographic evaluation at mid-term to long-term follow-up. Forearm and wrist motion was evaluated. Posteroanterior and lateral radiographs of both forearms were assessed for radial inclination, lunate subsidence, and arthritis changes. A Disabilities of the Arm, Shoulder and Hand (DASH) survey was completed. RESULTS: Twenty-seven patients underwent volar ligament release and distal radial dome osteotomy. Eight patients were either lost to follow-up or were unable to return for follow-up. Nineteen patients with thirty-one operatively treated wrists were available for follow-up. After further review, eighteen patients and twenty-six wrists were included in the study. The average age at the time of follow-up was twenty-five years (range, nineteen to thirty-one years), with an average length of follow-up of eleven years (range, seven to fourteen years). There was no change in radial inclination or in wrist motion between the immediate postoperative and long-term follow-up evaluations. There was a positive correlation between the amount of deformity correction based on more severe preoperative parameters and an increased arthritic grade at the time of follow-up. There was positive correlation between an increased DASH score and arthritis grade as well as a correlation between whole bone deformity and increased arthritis grade and DASH score. CONCLUSIONS: Volar ligament release and distal radial dome osteotomy for Madelung deformity provides lasting correction of the deformity. Long-term follow-up shows maintenance of original radiographic correction with good to excellent functional outcome. Patients with radiographic evidence of more severe disease preoperatively and the whole bone variety of Madelung deformity have poorer radiographic outcomes and trend toward poorer functional outcomes.

Incidence of abdominal tumors in syndromic and idiopathic hemihypertrophy/isolated hemihyperplasia.

BACKGROUND: There is a reported increased risk of intra-abdominal tumors in children with both syndromic (SH) and isolated idiopathic hemihyperplasia (IH). Recommendations for tumor surveillance have been made, although there is no consensus for frequency and duration of screening. Our objective was to review the incidence of abdominal neoplasms in our pediatric population with SH and IH. METHODS: We reviewed the diagnostic criteria, imaging findings, and any associated syndrome in all patients diagnosed with hemihypertrophy over a 10-year period. RESULTS: One of 10 patients with SH, a child with Beckwith-Wiedemann syndrome, developed a hepatoblastoma resulting in a 10% tumor incidence in patients with SH. Three of the 250 (1.2%) children with IH developed an abdominal neoplasm. One was diagnosed with adrenal carcinoma and the other 2 with Wilms tumor. CONCLUSIONS: We found an increased incidence of abdominal tumors in both SH and IH, however, our incidence of tumors with IH is lower than earlier reported studies. On the basis of this lower 1.2% incidence, the current literature on IH and available molecular genetic testing, it is reasonable to recommend referral of these patients to a clinical geneticist to identify subgroups with a higher risk for tumor development that are more likely to benefit from routine imaging surveillance. LEVEL OF EVIDENCE: II-Retrospective study.

Oculodentodigital dysplasia: ulnar-sided syndactyly and its associated disorders.

PURPOSE: Hand surgeons are often the first specialists to see patients with oculodentodigital dysplasia (ODDD), when infants with ulnar-sided syndactyly are referred. Major associated problems include neurologic, ophthalmologic, dental, and other skeletal abnormalities. The purposes of this study were to investigate the incidence of the reported associated conditions in the families of our patients with ODDD, correlate them with the severity of syndactyly, and provide better counseling with more accurate information for these patients and families. METHODS: We reviewed medical records from Texas Scottish Rite Hospital for Children from 1980 to 2009 to identify patients with ODDD. These patients and families were invited to return for a detailed medical and family history and physical examination documenting hand, foot, eye, dental, and facial findings. RESULTS: A total of 73 pediatric patients from 47 families were diagnosed with ODDD, and 38 individuals in 31 families agreed to participate in the study. We observed bilateral syndactyly in 32 patients, with symmetric involvement in 31 of these. Abnormalities of the shape and size of the middle phalanx of the small finger were common. Ophthalmological findings were present in 31 and dental abnormalities identified in 33 patients. Neurologic findings likely related to ODDD were found in 11 patients. There appeared to be an association between the severity of syndactyly and the severity of dental and urologic findings, but not ophthalmologic or neurologic findings such as paraparesis or cognitive deficits. CONCLUSIONS: We found a 29% incidence of neurologic manifestations in patients with ODDD. In addition, associated ophthalmologic, dental, and developmental conditions are frequent and a heightened awareness will allow appropriate referrals for patients with ulnar-sided syndactyly in ODDD. TYPE OF STUDY/LEVEL OF EVIDENCE: Prognostic IV.

Asymmetrical arthrogryposis of the upper extremity associated with congenital spine anomalies.

BACKGROUND: The term arthrogryposis is a descriptive term referring to a variety of clinical conditions characterized by multiple joint contractures. The spine may be involved; however, the presence of associated congenital vertebral abnormalities is rare. METHODS: A retrospective chart review of 6 patients with asymmetric upper extremity joint contractures and concomitant congenital scoliosis of the cervical spine was performed. RESULTS: Six patients with congenital anomalies of the cervical spine and asymmetric contractures of the upper extremities were identified. Clinical findings and radiographic studies were reviewed. Upper extremity involvement was contralateral to the convexity of the spinal curvature in 5 of the 6 cases. Reconstruction of the upper extremity was required in 5 of 6 patients; however, no patient required operative intervention for their congenital cervical scoliosis. CONCLUSIONS: Congenital cervical spine anomalies can be associated with asymmetric arthrogryposis of the upper extremities. Physicians who take care of pediatric patients with arthrogryposis should carefully evaluate the cervical spine. LEVEL OF EVIDENCE: Level IV, case series.

Onabotulinum toxinA injection as an adjunct in the treatment of posterior shoulder subluxation in neonatal brachial plexus palsy.

BACKGROUND: Botulinum toxin A is used to treat contractures in children with spasticity by temporarily interfering with neural transmission at the motor end plate. In infants with brachial plexus palsy, posterior shoulder subluxation and dislocation are the result of muscle imbalance, in which neurologic recovery is evolving, and spasticity is not a deforming force. We postulated that temporary weakening of the shoulder internal rotator muscles with botulinum toxin A would facilitate reduction of the glenohumeral joint in such infants with early posterior shoulder subluxation or dislocation. METHODS: Thirty-five infants with posterior subluxation or dislocation of the shoulder due to brachial plexus palsy were treated with botulinum toxin A between January 1999 and December 2006, and were followed for a minimum period of one year. Records were reviewed for the severity of the palsy, age at time of treatment, recurrence of subluxation or dislocation, and the subsequent need for further treatment to reduce the glenohumeral joint. RESULTS: The average age at the time of shoulder reduction and botulinum toxin-A injection was 5.7 months. Six patients had a second injection. Reduction of the shoulder was maintained in twenty-four (69%) of the thirty-five patients. There were no complications related to the use of botulinum toxin A. CONCLUSIONS: Although there may be specific risks associated with its use, botulinum toxin-A injection into the internal rotator muscles is a useful adjunct to the treatment of early posterior subluxation or dislocation of the shoulder in infants with neonatal brachial plexus palsy, and may help to avoid the need for open surgical procedures to restore or maintain shoulder reduction.

Development and evaluation of an educational interactive CD-ROM for teens with cancer.

BACKGROUND: Cancer is the number one disease killer of children and adolescents in North America. For adolescents, this diagnosis comes at a particularly vulnerable stage. Educating adolescents with cancer from diagnosis through treatment teaches and empowers them. Increasing evidence shows that these adolescents want more information. Few educational tools exist for young cancer patients; none are interactive; therefore, a CD-ROM was developed to meet this need. PROCEDURE: Animation, voiceover, music, videos, and games were combined to develop a comprehensive multimedia CD-ROM to teach 12- to 18-year-olds with solid tumors about their disease, treatment, coping skills, and late effects in an interactive and non-threatening way. The CD-ROM was evaluated in a pre-post design with 65 subjects recruited from four pediatric oncology centers randomized to the CD-ROM or a "Handbook" containing analogous information. Pre-post questionnaires measured coping strategies, health locus of control, quality of life, cancer knowledge, and self-efficacy; post-test variables also included acceptability and use by teens, their families, and healthcare professionals. RESULTS: Teens receiving the CD-ROM were significantly more likely to increase their internal locus of control scores; however, no significant differences were observed on other measures, attributable in part to the study sample size. Among teens, acceptability was higher in the CD-ROM versus the Handbook group, but not different between the two parent groups. Pediatric oncology healthcare providers gave positive feedback on the CD-ROM. CONCLUSIONS: This CD-ROM is an innovative and engaging educational tool--the first portable interactive product with access on demand for adolescents with solid tumors.

Protecting health care workers from tuberculosis: a 10-year experience.

BACKGROUND: Cook County Hospital (CCH) is an inner-city, large public hospital. Twenty-five percent of Chicago's tuberculosis (TB) cases are diagnosed at CCH. We wanted to review and analyze interventions implemented over a 10-year period at CCH to prevent TB infection in health care workers. METHODS: We performed a retrospective review of interventions to prevent health care-associated tuberculosis. We collated and analyzed tuberculin skin test conversions in our employees for the same time period. RESULTS: From 1990 to 2002, we cared for over 1800 in-patients with tuberculosis. During 1992-1997, multiple interventions to eliminate health care-associated spread of tuberculosis were implemented. Tuberculin skin test conversions in our employees decreased markedly from January 1994 through December 2002. Two drops in tuberculin skin test conversion rates occurred: one after introduction of basic administrative and engineering controls and a second after we experienced a decrease in missed TB cases and the introduction of N-95 personal respirators with 1-time qualitative fit testing. CONCLUSION: Our annual health care worker skin test conversion rate fell significantly when our primary interventions were relatively simple administrative and engineering controls. Educating health care workers to promptly recognize patients with TB and placing exhaust fans to create negative-pressure respiratory isolation rooms were probably our 2 most potent infection control measures.

Healthy children's perceptions of medicines: a review.

BACKGROUND: Chronically ill children's perceptions of medicines have been widely studied, but healthy children's less often. However, information on healthy children's beliefs and attitudes about medicine use is needed to be able to target health education messages about medicines appropriately. OBJECTIVES: A literature review was performed to determine schoolchildren's attitudes, beliefs, and knowledge about medicines; autonomy in using medicines; expectations of using medicines; and questions about medicines, so as to guide the development of a medicine education curriculum and to inform health care professionals who communicate with children. METHODS: This study was a review of literature from 17 countries. RESULTS: The review indicated that children of school age tend to view medicines cautiously. Although age is a factor, children have very limited ideas about how medicines work and issues around medicine efficacy are confusing to them. Even young children recognize that medicines may have harmful effects and, children of all ages and cultures studied want to learn more about medicines. Autonomy in medicine use is surprisingly high and disturbing given that knowledge of medicines is poor. CONCLUSIONS: Primary conclusions drawn are (1) children of the same age in different cultures appear similar in their attitudes, beliefs, behaviors, and desires to learn about medicines; (2) children lack information about medicines, especially in view of their levels of autonomy; and (3) health educators and health care professionals should educate children about rational medicine use, at appropriate cognitive development levels, before the children become independent medicine users.

Reducing antibiotics for colds and flu: a student-taught program.

A student peer-taught program, to decrease antibiotic use for colds and flu, was developed and implemented in one school district (21 schools) in Chisinau, Moldova, in 2003-04. A second district (20 schools) served as the control (C). Students (12-13 years) and adults most responsible for the family's health care completed surveys in March pre-post intervention. The surveys determined the reported incidence of colds and flu during the past winter, treatment, beliefs about cause and usefulness of antibiotics. The intervention included peer-education sessions, parents' meetings, booklet, vignette video, newsletters, poster and poster contest. The intervention also provided basic information on appropriate use of medicines. Pre-post intervention survey results indicated that the intervention was successful. Adjusted for Cs, students who reported they did not treat colds or flu with antibiotics increased 33.7%; the comparable increase for adults was 38.0%. Adjusted for Cs, intervention students who did not know if they had used an antibiotic decreased 15.1% and for intervention adults the comparable decrease was 5.0%. All relative responses related to beliefs about the cause of colds and flu and the usefulness of antibiotics to treat them changed in a positive direction. In all groups, beliefs and behaviors relative to antibiotic use were related.

A prospective evaluation of the WeeFIM in patients with cerebral palsy undergoing orthopaedic surgery.

PURPOSE: Although frequently used in pediatric rehabilitation settings, the WeeFIM has not been tested in surgical pediatric orthopaedic patients. METHODS: The WeeFIM was administered to patients with surgical cerebral palsy at defined intervals preoperatively and at both 6 and 12 months postoperatively. The age-adjusted change scores from baseline to follow-up were tested both parametrically and nonparametrically. RESULTS: Four hundred sixty-eight patients had baseline evaluations. There were 161 six-month follow-up assessments and 108 twelve-month follow-up assessments. The baseline WeeFIM was able to separate children with different patterns of cerebral palsy. Hemiplegic patients had higher scores than diplegic and tetraplegic patients. Overall age-adjusted scores were improved at both 6 (mean increase 2.0) and 12 months (mean increase 2.2). The instrument showed significant ceiling effects for diplegic and hemiplegic patients with lower or upper extremity surgery and limited responsiveness for lower extremity surgery in tetraplegic patients. Parametrically, it showed improvements in mobility for both rhizotomy and tetraplegic upper extremity surgery. Nonparametric tests were not significant for rhizotomy mobility improvement. CONCLUSIONS: Although the WeeFIM adequately reflects the severity of neurological involvement in pediatric orthopaedic patients with cerebral palsy, it has a significant ceiling effect in diplegic and hemiplegic patients limiting responsiveness and lacks content validity for tetraplegic patients. The instrument may have some use in tetraplegic patients with upper extremity surgery and in rhizotomy patients. We recommend against its general use for orthopaedic surgery in patients with cerebral palsy lower extremity or spine surgery and in hemiplegic patients with upper extremity surgery.

How well can children understand medicine related topics?

The aim of this study was to discover how well children understand medicine related topics and in this way to evaluate their preparedness for two-way communication about these matters. The data were collected by conducting 14 focus group discussions (FGDs) among Finnish schoolchildren aged 7-8, 10-11 and 13-14 years. The main theme during the FGDs was the management of diseases with medicines. Both inductive and deductive analyses were used to analyse the data [Patton M. Qualitative evaluation and research methods. 2nd ed. Newbury Park: Sage Publications; 1990]. Children had superficial knowledge of and a negative attitude towards medicine use. They used medicine related vocabulary uncertainly implying that they do not fully comprehend all the information that they have gained. Children realized that there may be risks when using medicines and this understanding tended to increase by age. The results of this study indicate a need to educate children about medicines. In addition to school-based medicine education, health care professionals should communicate directly with children about their medicines at an appropriate cognitive level in order to increase their understanding and skills concerning health issues.

Developing a medicine education program in Finland: lessons learned.

The aim of this article is to describe the process of developing a medicine education program for elementary and middle schools in Finland and the lessons learned during the process. Further described is how teachers evaluated the usefulness of the medicine education materials created during the process. By medicine education we mean education about the proper use of medicines, abuse of medicines being just a small part of it. The development process started in 2002 by conducting focus group discussions with children in order to discover how children of different ages understand medicine-related topics. Moreover, teachers completed questionnaires in 2002 to assess their opinions about the importance of medicine education as a part of school health education. Based on the results of these two studies, materials were created during 2002-2003 (, in Finnish with an English introduction). These materials gave the teachers information about the proper use of medicines and some ideas for assignments. As a last part of this research project in autumn 2003, the materials were piloted by a group of elementary and middle school teachers (n=14), and the usefulness of the materials were evaluated during focus group discussions after a teaching period. Based on the evaluation, we learned that the Website should contain a simple structure and ready-to-use materials in order to be used by teachers. Moreover, the fact that teachers need information in order to be able to teach this unfamiliar topic became clear. Teachers of younger children need concise information, but teachers of adolescents need more in-depth information. Furthermore, teachers may have negative attitudes towards medicines, and therefore, medicine education should be rationalized for them. We conclude our article with recommendations on what should be taken into consideration when medicine education programs are planned.

Physician use of a participatory decision-making style with children with ADHD and their parents.

The purpose of this study was to examine the extent to which physicians reported using a participatory decision-making (PDM) style with children and their parents during attention-deficit/hyperactivity disorder visits and the physician characteristics that were related to physician use of a PDM style. The survey was sent to a stratified random sample of 250 pediatricians and 250 family practitioners that were licensed and actively practicing in North Carolina. A second mailing of the survey was sent to non-responders approximately 3 weeks after the first mailing was sent. Approximately 47% of the physicians responded. Physicians were significantly more likely to rate themselves as more participatory with parents than with children. Younger physicians were more likely to use a participatory style with attention-deficit/hyperactivity disorder (ADHD) children. Physicians who rated themselves as using a more participatory style with parents, also rated themselves as being more participatory with children. Pediatricians and younger physicians were more likely to use a participatory style with parents of ADHD children. The majority of physicians believed that ADHD children could begin to contribute to decisions about the diagnosis and treatment of ADHD during medical visits from age 7 to 11 years.

Computer equipment used in patient care within a multihospital system: recommendations for cleaning and disinfection.

Computer hardware has been implicated as a potential reservoir for infectious agents. Leaders of a 22-hospital system, which spans North America and serves pediatric patients with orthopedic or severe burns, sought to develop recommendations for the cleaning and disinfection of computer hardware within its myriad patient care venues. A task force comprising representatives from infection control, medical affairs, information services, and outcomes management departments was formed. Following a review of the literature and of procedures within the 22 hospitals, criteria for cleaning and disinfection were established and recommendations made. The recommendations are consistent with general environmental infection control cleaning and disinfection guidelines, yet flexible enough to be applicable to the different locales, different computer and cleaning products available, and different patient populations served within this large hospital system.

Do pictograms improve children's understanding of medicine leaflet information?

There is a growing need for balanced drug information customized for special target groups such as children [Food and Drug Administration. Prescription Drug Product Labeling; Medication Guide Requirements; Proposed Rule. Part VII. Department of Health and Human Services, 21 CRF Part 201, et al. Federal Register 1995;60:44182-252; Dickinson D, Raynor DK, Duman M. Patient information leaflets for medicines: using consumer testing to determine the most effective design. Patient Educ Couns 2001;43:147-59]. Pictograms are one aid that may be used to make information easier to read and understand. The aim of this study was to test whether children understand pictograms developed by the United States Pharmacopeia (USP) [The United States Pharmacopeial Convention Inc. USP Pictograms. Retrieved 11 March 2002 from http://www.usp.org/], and especially, if the pictograms improve children's understanding of medicine leaflet information. Finnish elementary school children aged 7 years (n=28), 11 years (n=31) and 13 years (n=31) were interviewed and asked what they thought 15 USP pictograms mean. The two older age groups were also asked to read an "easy-to-read" leaflet for penicillin-V. Every second child was given a leaflet with a plain text and the others received the same text accompanied by pictograms. After reading the leaflet, the children were asked seven questions related to the text. Most of the children understood the meanings of the selected 15 pictograms correctly, the proportion of the correct explanations varying from 30 to 99% according to the pictogram. Even well-understood pictograms did not help the children understand the leaflet information, although they reduced the need for probing. This study shows that the context in which pictograms are tested makes a difference in the results. Testing plain pictograms without incorporating them in their real context, e.g., in the patient information leaflet may exaggerate their usefulness in leaflet information.
