Five-year trends in induction of labour in a large Australian metropolitan maternity service.

BACKGROUND: The World Health Organisation recommends that induction of labour (IOL) be performed only with a clear medical indication. Australian rates of IOL appear to be rising, with more than one-third of women having labour induced. This may reflect changing clinician and consumer perceptions of the benefits and potential harms of term IOL. AIMS: To understand recent trends in the rates and indications for IOL. MATERIALS AND METHODS: A retrospective cohort study was undertaken in a Level 6 maternity facility, in metropolitan South-East Queensland, Australia. Routinely collected data were gathered between 2015 and 2020. Exclusion criteria were multiple pregnancies, stillbirth and pre-labour rupture of membranes. Pre-labour rupture of membranes was excluded due to inability to assess if IOL for this indication was a true induction or augmentation of labour. Indications for induction were grouped into maternal, fetal, elective indications, 'post-dates' and decreased fetal movements (DFM). Rates of IOL and frequency of the various indications were compared over time. RESULTS: About 46 530 livebirths occurred during the study period, with labour induced in 31.7%. The proportion of women undergoing IOL increased from 29.8% in 2015 to 33.4% in 2019 (P < 0.001). The proportion of inductions for DFM and elective indications increased over time, with a substantial decrease in 'post-dates' IOL. CONCLUSIONS: This large contemporary analysis of IOL trends in Australia has demonstrated rising rates and changing indications for IOL. There remain large knowledge gaps in areas such as care of women with DFM, definitions and management of 'post-term pregnancy', and the economic and service impacts of rising trends in the rate of IOL.

Electronic palliative care co-ordination system: an electronic record that supports communication for end-of-life care - a pilot in Richmond, UK.

Most people prefer to die at home, however, the majority die in an acute hospital. Supporting a patient in their preferred place of care may be aided by exchange of information across sectors. Richmond piloted an electronic palliative care coordination system (EPaCCS) to enhance interprofessional communication for end-of-life care. One such EPaCCS is the Coordinate My Care (CMC) hosted by the Royal Marsden NHS Foundation Trust, now supported across London. It focused clinicians on having advance care planning conversations with patients and their carers and then documenting the outcome onto an electronic web-based record that can be shared with key healthcare professionals.

A model based on age, sex, and morbidity to explain variation in UK general practice prescribing: cohort study.

OBJECTIVE: To examine whether patient level morbidity based measure of clinical case mix explains variations in prescribing in general practice. DESIGN: Retrospective study of a cohort of patients followed for one year. SETTING: UK General Practice Research Database. PARTICIPANTS: 129 general practices, with a total list size of 1 032 072. MAIN OUTCOME MEASURES: Each patient was assigned a morbidity group on the bases of diagnoses, age, and sex using the Johns Hopkins adjusted clinical group case mix system. Multilevel regression models were used to explain variability in prescribing, with age, sex, and morbidity as predictors. RESULTS: The median number of prescriptions issued annually to a patient is 2 (90% range 0 to 18). The number of prescriptions issued to a patient increases with age and morbidity. Age and sex explained only 10% of the total variation in prescribing compared with 80% after including morbidity. When variation in prescribing was split between practices and within practices, most of the variation was at the practice level. Morbidity explained both variations well. CONCLUSIONS: Inclusion of a diagnosis based patient morbidity measure in prescribing models can explain a large amount of variability, both between practices and within practices. The use of patient based case mix systems may prove useful in allocation of budgets and therefore should be investigated further when examining prescribing patterns in general practices in the UK, particularly for specific therapeutic areas.

Tight glycaemic control: a prospective observational study of a computerised decision-supported intensive insulin therapy protocol.

INTRODUCTION: A single centre has reported that implementation of an intensive insulin protocol, aiming for tight glycaemic control (blood glucose 4.4 to 6.1 mmol/l), resulted in significant reduction in mortality in longer stay medical and surgical critically ill patients. Our aim was to determine the degree to which tight glycaemic control can be maintained using an intensive insulin therapy protocol with computerized decision support and to identify factors that may be associated with the degree of control. METHODS: At a general adult 22-bed intensive care unit, we implemented an intensive insulin therapy protocol in mechanically ventilated patients, aiming for a target glucose range of 4.4 to 6.1 mmol/l. The protocol was integrated into the computerized information management system by way of a decision support program. The time spent in each predefined blood glucose band was estimated, assuming a linear trend between measurements. RESULTS: Fifty consecutive patients were investigated, involving analysis of 7,209 blood glucose samples, over 9,214 hours. The target tight glycaemic control band (4.4 to 6.1 mmol/l) was achieved for a median of 23.1% of the time that patients were receiving intensive insulin therapy. Nearly half of the time (median 48.5%), blood glucose was within the band 6.2 to 7.99 mmol/l. Univariate analysis revealed that body mass index (BMI), Acute Physiology and Chronic Health Evaluation (APACHE) II score and previous diabetes each explained approximately 10% of the variability in tight glycaemic control. BMI and APACHE II score explained most (27%) of the variability in tight glycaemic control in the multivariate analysis, after adjusting for age and previous diabetes. CONCLUSION: Use of the computerized decision supported intensive insulin therapy protocol did result in achievement of tight glycaemic control for a substantial percentage of each patient's stay, although it did deliver 'normoglycaemia' (4.4 to about 8 mmol/l) for nearly 75% of the time. Tight glycaemic control was difficult to achieve in critically ill patients using this protocol. More sophisticated methods such as continuous blood glucose monitoring with automated insulin and glucose infusion adjustment may be a more effective way to achieve tight glycaemic control. Glycaemia in patients with high BMI and APACHE II scores may be more difficult to control using intensive insulin therapy protocols. Trial registration number 05/Q0505/1.

Association of age, sex and deprivation with quality indicators for diabetes: population-based cross sectional survey in primary care.

OBJECTIVES: To determine the quality of diabetes management in primary care after the publication of the National Service Framework and examine the impact of age, gender and deprivation on the achievement of established quality indicators. DESIGN: Population-based cross sectional survey using electronic general practice records carried out between June-October 2003. SETTING: Thirty-four practices in Wandsworth, South-West London, UK. PARTICIPANTS: 6035 adult patients (> or =18 years) with diabetes from a total registered population of 201,572 patients. INTERVENTIONS: None. MAIN OUTCOME MEASURES: Success rates for the diabetes quality indicators within the General Medical Services contract for general practitioners. RESULTS: We identified large variations in diabetes management between general practitioner practices with poorer recording of quality care in younger patients (18-44 years). In addition, younger patients had a worse cholesterol and glycaemia profile, although hypertension was more common in older patients. Gender and deprivation did not appear to be important determinants of the quality of care received. CONCLUSIONS: There are large variations in diabetes management between general practitioner practices, with care seemingly worse for younger adults. Longitudinal studies are required to determine whether current UK quality improvement initiatives have been successful in attenuating existing variations in care and treatment outcomes.

The effect of heparin on graft thrombosis in pediatric renal allografts.

Graft thrombosis is an important cause of early (<4 weeks) renal graft loss. Reports show that heparin reduces the incidence of early renal allograft thrombosis. Routine peri-operative administration of unfractionated heparin was introduced in our unit in 1994. We conducted a retrospective study of 254 transplants, undertaken in children, between 1987 and 2000. There were 126 children who did not receive heparin (group 1) and 128 who did (group 2). Recipient characteristics and immunosuppression were similar in both groups. The incidence of graft loss secondary to thrombosis was compared between the groups. Variables previously identified with increased risk of graft loss, including donor age, recipient age, cold ischaemia time (CIT), multiple donor vessels, surgical complications, and side of graft donation, were examined using logistic regression. Thrombosis occurred in 14 grafts in group 1 and 11 grafts in group 2 (odds ratio 0.7, 95% confidence interval 0.3-1.6, P=not significant). The mean time to graft loss was similar in groups 1 and 2 (6.6, SD 3.9, range 2-12 days and 7.9, SD 4.4, range 1-14 days, respectively) ( P=0.445). Young recipient age ( P=0.006), young donor age ( P=0.009), increasing CIT ( P=0.007), and surgical complications ( P=0.002) increased the risk of graft thrombosis. A reduction in the incidence of early renal allograft thrombosis upon introduction of heparin was not demonstrated.

Value of sequential monitoring of left ventricular ejection fraction in the management of thalassemia major.

Regular monitoring of left ventricular ejection fraction (LVEF) for thalassemia major is widely practiced, but its informativeness for iron chelation treatment is unclear. Eighty-one patients with thalassemia major but no history of cardiac disease underwent quantitative annual LVEF monitoring by radionuclide ventriculography for a median of 6.0 years (interquartile range, 2-12 years). Intraobserver and interobserver reproducibility for LVEF determination were both less than 3%. LVEF values before and after transfusion did not differ, and exercise stress testing did not reliably expose underlying cardiomyopathy. An absolute LVEF of less than 45% or a decrease of more than 10 percentage units was significantly associated with subsequent development of symptomatic cardiac disease (P <.001) and death (P =.001), with a median interval between the first abnormal LVEF findings and the development of symptomatic heart disease of 3.5 years, allowing time for intervention. In 34 patients in whom LVEF was less than 45% or decreased by more than 10 percentage units, intensified chelation therapy was recommended (21 with subcutaneous and 13 with intravenous deferoxamine). All 27 patients who complied with intensification survived, whereas the 7 who did not comply died (P <.0001). The Kaplan-Meier estimate of survival beyond 40 years of age for all 81 patients is 83%. Sequential quantitative monitoring of LVEF is valuable for assessing cardiac risk and for identifying patients with thalassemia major who require intensified chelation therapy.

Mouth opening: a new angle.

BACKGROUND: The authors hypothesized that craniocervical extension occurs during normal mouth opening. METHODS: Twenty volunteers were studied. Interdental distance was measured at four different degrees of craniocervical extension. RESULTS: Interdental distance increased from 28 mm (95% confidence interval, 25-30) in slight flexion to 46 mm (95% confidence interval, 42-49) at full extension. Nearly maximal mouth opening was obtained with 26 degrees (95% confidence interval, 22-30) of craniocervical extension from neutral. CONCLUSION: Craniocervical extension is an integral part of complete mouth opening in conscious subjects. Fixation of the craniocervical junction by disease, an internal or external fixation device, or technique may restrict mouth opening, with consequences for airway management.
