Audit of oxygen administration to achieve a target oxygen saturation range in acutely unwell medical patients

Purpose of the studyTo evaluate documentation of a target oxygen saturation (SpO2) range and ability to achieve this range in acutely unwell inpatients.Study designIn this single-centre audit, patients with discharge diagnoses of pneumonia, heart failure and exacerbation of asthma or COPD admitted to Wellington Regional Hospital, New Zealand between 1 June 2019 and 31 August 2019 who received oxygen were identified. In those with a documented target SpO2 range, the proportion of SpO2 measurements in the observation chart which were within, above and below range were determined as well as the maximum and minimum SpO2. Regression analysis was performed to determine whether these outcomes were influenced by the prescribed range, high-dependency care or the number of adjustments to oxygen administration.Results268 admissions were screened. Of the 100 eligible admissions who received oxygen, a target SpO2 range was documented in 62. The mean (SD) proportion of SpO2 measurements within range was 56.2 (30.6)%. A hypercapnic target SpO2 range was associated with a higher probability of an SpO2 above range; multivariate OR 5.34 (95% CI 1.65 to 17.3, p=0.006) and a lower probability of an SpO2 below range; multivariate OR 0.25 (95% CI 0.08 to 0.80) p=0.02. The mean (SD) maximum SpO2 was similar in those with a target range of 92%–96% versus a hypercapnic range; 96.2 (3.0)% and 95.2 (3.4)%, respectively.ConclusionsOxygen prescription and delivery in this clinical setting was suboptimal. SpO2 values above the designated range are common, particularly in patients with a hypercapnic target range.

Inserting central lines via the peripheral circulation in neonates

Peripherally inserted central catheters (PICCs) are extensively used in neonatal intensive and high-dependency care settings. These intravenous catheters provide medium to longer-term access to the circulatory system for the delivery of medications, parenteral nutrition and the like. Catheters are available in a variety of bespoke designs and materials, each with their unique characteristics, benefits and limitations. PICCs are frequently inserted in a sterile zone cot-side procedure, one that requires an advanced knowledge base, technical skill and training. This article relates some important practical advice around managing minor complications that can be encountered while using the modified Seldinger technique (MST) to insert neonatal PICCs, which can make this procedure a less stressful experience for both infants and health professionals.

Emergency and high dependency care

Recognition and management of the sick child can generate significant challenges and anxiety for the clinician assessing children presenting with acute medical problems. The shear breadth of differential diagnoses, as well as the pressures of minimizing avoidable hospital admission, can seem daunting. The commonest presentations are detailed in this chapter, with the initial management steps required to stabilization.

Emergency paediatric critical care in England: describing trends using routine hospital data

ObjectiveTo determine trends in emergency admission rates requiring different levels of critical care in hospitals with and without a paediatric intensive care unit (PICU).DesignBirth cohort study created from Hospital Episode Statistics.SettingNational Health Service funded hospitals in England.Patients8 577 680 singleton children born between 1 May 2003 and 31 April 2017.Outcome measuresUsing procedure and diagnostic codes, we assigned indicators of high dependency care (eg, non-invasive ventilation) or intensive care (eg, invasive ventilation) to emergency admissions.InterventionsChildren were followed up until their fifth birthday to estimate high dependency and intensive care admission rates in hospitals with and without a PICU. We tested the yearly trend of high dependency and intensive care admissions to hospitals without a PICU using logistic regression models.ResultsEmergency admissions requiring high dependency care in hospitals without a PICU increased from 3.30 (95% CI 3.09 to 3.51) per 10 000 child-years in 2008/2009 to 7.58 (95% CI 7.28 to 7.89) in 2016/2017 and overtook hospitals with a PICU in 2015/2016. The odds of an admission requiring high dependency care to a hospital without a PICU compared with a hospital with a PICU increased by 9% per study year (OR 1.09, 95% CI 1.08 to 1.10). The same trend was not present for admissions requiring intensive care (OR 1.01, 95% CI 0.99 to 1.03).ConclusionsBetween 2008/2009 and 2016/2017, an increasing proportion of admissions with indicators of high dependency care took place in hospitals without a PICU.

Complications of measles: a case series

Measles, which was once thought to be a disappearing viral infection due to effective vaccination, has been re-emerging globally, with increasing cases in adolescents and adults. This has been attributed to anti-vaccination campaigning in the early 21st century, which has resulted in a drop in overall herd immunity. In this case series we report three patients with complications secondary to measles who presented to a hospital in Malta in 2019. Through this series, we discuss the range of possible complications caused by the measles virus, ranging from mild viraemic symptoms to multiorgan involvement which could possibly lead to high-dependency care and may even be fatal. We also highlight recent global statistics which reflect the exponential increase in the incidence of measles, with a special focus on Europe. It is emphasised that vaccine education and compliance with the two-dose measles vaccine should be implemented worldwide.

What factors influence midwives to provide obstetric high dependency care on the delivery suite or request care be escalated away from the obstetric unit? Findings of a focus group study

Background In the United Kingdom, midwives will engage in discussions with the multidisciplinary team as to whether they can provide Obstetric High Dependency Care (OHDC) on the Delivery Suite or whether a woman’s care should be escalated to the critical care team. This study aimed to explore the question: What factors influence midwives to provide OHDC or request care be escalated away from the obstetric unit in hospitals remote from tertiary referral centres? Methods Focus groups were undertaken with midwives (n = 34) across three obstetric units in England, with annual birth rates ranging from 1500 to 5000 per annum, in District General Hospitals. Three scenarios in the form of video vignettes of handover were used as triggers for the focus groups. Scenario 1; severe pre-eclampsia, physiologically unstable 2; major postpartum haemorrhage requiring invasive monitoring 3; recent admission of woman with chest pain receiving facial oxygen and requiring continuous electrocardiogram (ECG) monitoring. Two focus groups were conducted in each of the obstetric units with experienced midwives. Data were analysed using a qualitative framework approach. Results Factors influencing midwives’ care escalation decisions included the care environment, a woman’s diagnosis and fetal or neonatal factors. The overall plan of care including the need for ECG and invasive monitoring were also influential factors. Midwives in the smallest obstetric unit did not have access to the facilities for OHDC provision. Midwives in the larger obstetric units provided OHDC but identified varying degrees of skill and sometimes used ‘workarounds’ to facilitate care provision. Midwifery staffing levels, skill mix and workload were also influential. Some differences of opinion were evident between midwives working in the same obstetric units as to whether OHDC could be provided and the support they would enlist to help them provide it. Reliance on clinical guidelines appeared variable. Conclusions Findings indicate that there may be inequitable OHDC provision at a local level. Organisationally robust systems are required to promote safe, equitable OHDC care including skills development for midwives and precise escalation guidelines to minimise workarounds. Training for midwives must include strategies that prevent skills fade.
