Summary Background Acute diarrhoeal disease management often requires rehydration alone without antibiotics. However, non-indicated antibiotics are frequently ordered and this is an important driver of antimicrobial resistance. The mHealth Diarrhoea Management (mHDM) trial aimed to establish whether electronic decision support improves rehydration and antibiotic guideline adherence in resource-limited settings. Methods A cluster randomised controlled trial was done at ten district hospitals in Bangladesh. Inclusion criteria were patients aged 2 months or older with uncomplicated acute diarrhoea. Admission orders were observed without intervention in the pre-intervention period, followed by randomisation to electronic (rehydration calculator) or paper formatted WHO guidelines for the intervention period. The primary outcome was rate of intravenous fluid ordered as a binary variable. Generalised linear mixed-effect models, accounting for hospital clustering, served as the analytical framework; the analysis was intention to treat. The trial is registered with ClinicalTrials.gov ( NCT03154229 ) and is completed. Findings From March 11 to Sept 10, 2018, 4975 patients (75·6%) of 6577 screened patients were enrolled. The intervention effect for the primary outcome showed no significant differences in rates of intravenous fluids ordered as a function of decision-support type. Intravenous fluid orders decreased by 0·9 percentage points for paper electronic decision support and 4·2 percentage points for electronic decision support, with a 4·2-point difference between decision-support types in the intervention period (paper 98·7% [95% CI 91·8–99·8] vs electronic 94·5% [72·2–99·1]; pinteraction=0·31). Adverse events such as complications and mortality events were uncommon and could not be statistically estimated. Interpretation Although intravenous fluid orders did not change, electronic decision support was associated with increases in the volume of intravenous fluid ordered and decreases in antibiotics ordered, which are consistent with WHO guidelines.

Objective: To document and critically analyse the impact of the revised WHO 2000 histological classification for meningiomas on postoperative radiotherapy/radiosurgery indications and MRI follow up protocols. Methods: The current (2000) WHO classification was used to grade 57 meningiomas treated surgically at one institution. These had been reviewed previously in 1999. All German neurosurgical departments carrying out intracranial microsurgery were asked to detail their guidelines for radiation therapy and follow up for meningiomas of different WHO grades. Results: Use of the current criteria downgraded seven of 15 atypical meningiomas (WHO grade II, MII) to grade I (MI), and four of six anaplastic tumours (WHO grade III, MIII) to grade II. Indications for radiotherapy/radiosurgery and MRI follow up protocols varied substantially with the histological grade and between institutions—for example, after an incomplete resection, radiotherapy/radiosurgery recommendations differed between MI and MII in 30 of 58 units (52%), and between MII and MIII in 34 of 56 units (61%). Conclusions: Correlative studies combining treatment and outcome data with a standardised histopathological analysis are warranted to define properly the indications for radiotherapy/radiosurgery and follow up protocols after surgery for meningiomas of different histological grades. The use of changing grading paradigms during recent years renders decision making based on local and published experience difficult. The relatively large number of meningiomas classified as atypical/WHO grade II in current practice would argue against an uncritically aggressive approach to these tumours.
