• Examining Infectious Complications Following Lumbar Puncture in Children. Clinical pediatrics Seddik, T. B., Burns, J. E., Chen, S. F., Schwenk, H. T., Liao, Y., Horstman, K., Waris, R., Dos Santos, L. M. 2024: 99228241293901

  Abstract

  Little is known about infectious complications of lumbar puncture (LP) in children. We reviewed records of children with bacterial meningitis, intraspinal abscess, and vertebral osteomyelitis over a 3-year period to identify infections following LP. Four children with bacterial meningitis and 1 child with vertebral osteomyelitis were identified and their clinical presentations were described. These cases were scored by infectious disease experts, using a Likert scale, for the possibility of iatrogenic causation; these scores were variable, reflecting uncertainty. The bacterial meningitis cases had repeat LPs, and the latter cerebrospinal fluid analyses were diagnostic of bacterial meningitis; the interval between the initial "index" LP (I-LP) and symptom onset was 8 to 10 hours in most cases. Pediatricians should be aware of this possibility, and have a low threshold to repeat LP if there is a clinical change after the I-LP that could be consistent with meningitis.

• Improving Family-Centered Rounds With a Nursing Checklist in the Electronic Health Care Record. Hospital pediatrics Madduri, G. B., Nichols, T., Gunturkun, F., Johnson, D., Lum, A., Shaner, M. A., Weng, Y., Srinivas, N., Dos Santos, L. 2024; 14 (11): 919-927

  Abstract

  Family-centered rounds (FCR) is the standard for pediatric communication, but community pediatric hospital medicine services may face barriers in implementation, including offering FCR to families with a language preference other than English (LOE) versus those with an English preference (EP). The goal of our quality improvement project was to increase FCR from 33% to 80% over 1 year.Interventions included an FCR checklist integrated into the electronic healthcare record (EHR-FCR checklist), staff education, visual prompts, and interpreters. Our primary outcome measure was weekly % FCR. Our main process measure was weekly % nursing documentation. To address language inclusion, we compared FCR encounters for families with LOE versus EP. The use of the checklist without interventions was assessed during the sustain period. Control charts were used to analyze measures. Fisher's exact test was used to compare FCR for families with LOE versus EP.FCR increased to 81% during the intervention period and then decreased to 73% during the sustain period. Nursing documentation increased to 93% with the EHR-FCR checklist implemented as a flowsheet. There was no statistical difference in the proportion of families with LOE versus EP who participated in FCR (84% versus 81%, P = .38) during the intervention period; a statistically higher proportion of families with LOE participated in FCR during the sustain period (87% vs 72%, P <.01).We increased documented FCR on our community pediatric hospital medicine service, including FCR for families with LOE, by implementing a nursing-completed EHR-FCR checklist supported by staff education, visual prompts, and interpreters.

• SOFT-TISSUE SWELLING WITH FRACTURES - ABUSE VERSUS NONINTENTIONAL PEDIATRIC EMERGENCY CARE DOSSANTOS, L. M., Stewart, G., Meert, K., Rosenberg, N. M. 1995; 11 (4): 215-216

  Abstract

  The objectives were to 1) define the amount of postfracture swelling at presentation in long bone fractures, and 2) to study the relationship between suspected abuse and/or neglect (A/N) and degree of postfracture swelling at presentation. This was a prospective study of 37 patients less than 11 years of age presenting with long bone fractures to the emergency department (ED) of the Children's Hospital of Michigan between August 1992 and December 1992. Data were recorded at the time of the ED visit and from medical records which were reviewed four to six months later. Of the patients enrolled in the study, eight were categorized as A/N and 29 as nonintentional. There was no difference in reported injury age between the two groups (15.5 +/- 24.5 hours vs 14.0 +/- 17.7, P = 0.8). At presentation the mean increase in circumference from post-fracture swelling was 9.6 +/- 7.1%, using the uninjured extremity as the control. The abuse group had a lesser increase in circumference compared to the nonintentional group, even after adjusting for injury age (3.8 +/- 3.6% vs 11.2 +/- 7.0%, P < 0.006). We concluded that patients with long bone fractures had a mean swelling of 9.6 +/- 7.1% at presentation. Injuries induced by A/N present with less swelling than similar injuries sustained nonintentionally, and we speculate that this difference indicates that the history and/or time of injury may not be reliable.

• PEDIATRIC EMERGENCY DEPARTMENT WALK-OUTS PEDIATRIC EMERGENCY CARE DOSSANTOS, L. M., Stewart, G., Rosenberg, N. M. 1994; 10 (2): 76-78

  Abstract

  The objectives of this study were to determine reasons for leaving a pediatric emergency department before physician evaluation, any adverse outcomes of those leaving, and to assess whether the presence of an ombudsman altered the pattern. This was a prospective follow-up study of all patients who left the pediatric emergency department of the Children's Hospital of Michigan before physician evaluation between October 24, 1991 and January 30, 1992. Information was obtained from medical records and a telephone questionnaire with the parent or guardian one week later. A control group of patients (n = 150) evaluated in the same period were randomly selected for comparison and matched for triage acuity score, shift, and weekday/weekend visit. Five hundred and twelve patients left during this period. Contact was made with 82% (419). Forty-three percent of patients left only because of a long wait, and an additional 19% included a long wait as one of the reasons for leaving. There was a significantly longer waiting time for walk-outs compared with controls (188 +/- 76.4 vs 93.6 +/- 64.9 minutes, P < 0.0001). Of the 419 patients followed, 256 (61%) were seen by a physician within seven days, and seven (1.7%) were hospitalized. Three hundred one (72%) were reported to be well; 108 (26%) were better. No deaths occurred. Hospitalization rates were significantly lower for patients who left compared with patients who stayed over the same period of time (7/419 vs 1931/16,990, P < 0.0001). The presence of an ombudsman was associated with an increase in walk-outs.(ABSTRACT TRUNCATED AT 250 WORDS)
