Abstract:

Hypertension is a common presentation but there is no New Zealand based guideline for the management of severe asymptomatic hypertension (greater than 180 systolic or 110 diastolic) in urgent care. Definitions have varied in both naming ( hypertensive emergency, hypertensive urgency, hypertensive crisis ,malignant hypertension,accelerated hypertension, severe asymptomatic hypertension) and parameters.

Method:

A review of recent literature was conducted.

Abstract:

Rivaroxaban is well established as a treatment for deep vein thrombosis and pulmonary embolism, but there has been hesitation in using it as a bridging agent in clinical situations where DVT is suspected but not yet confirmed by definitive ultrasound scan. The evidence for the safety and efficacy of this approach is explored. During this time of research, the use of rivaroxaban began to gain acceptance and usage in New Zealand, leading to a brief analysis of factors involved in trying to introduce up to date guidelines into a small health organisation in New Zealand prior to widespread acceptance and definitive guidelines at District Health Board level.

Diverticulitis: the role of antibiotics in urgent care

Author: Dr Eleri Clissold

Abstract:

Our understanding of this common and painful disease is evolving. What was thought to be a predominantly infective process is postulated to be inflammatory and self-limiting in the majority of cases. Over several decades multiple high quality studies have emerged questioning the role of antibiotics in the management of acute diverticulitis without perforation, sepsis or other complications. No study has demonstrated the superiority of any antibiotic strategy in any one of multiple outcomes assessed. This literature search seeks to examine the evidence in-depth and place it in context for urgent care practitioners.

Abstract:
The pulled elbow(PE) is a common childhood injury. In most cases, the clinical management is straight forward, however, the diagnosis and management may be difficult if there is an unclear history, an unwitnessed injury or an atypical mechanism of injury. This medical literature project evaluates the effectiveness of point-of-care ultrasound in the diagnosis of PEs.

Nausea and Vomiting in Pregnancy (NVP)

Author: Dr Richard Chen

Abstract:

Aim: 

Nausea and Vomiting in Pregnancy (NVP) is a common presentation seen by a wide variety of medical professionals however the evidence around the safety and efficacy of drugs used to treat NVP is often not well understood. This review looks to explore current prescribing practices of drugs used to treat NVP and provide evidence-based recommendations. 

Method: 

The current New Zealand Guidelines for treatment of NVP was studied and an in-depth literature search into the safety and efficacy of drugs available was conducted.
In addition, a survey of current doctors working in the Urgent Care setting was conducted to determine current prescribing habits.

Results: 
Pyridoxine, Doxylamine and Metoclopramide are the medications with the most proven safety profile in pregnancy respectively. There have been significant studies into the Pyridoxine-Doxylamine combination as well as Metoclopramide to demonstrate effectiveness against placebo. However, there is insufficient evidence to suggest any drug is the most effective drug available.
A large proportion of prescribing preferences of the doctors working in Urgent Care surveyed in the context of treating NVP were not supported by the available evidence.

Conclusion:  

Considering both safety and efficacy, Pyridoxine and Doxylamine are the recommended initial drugs of choice to manage NVP. This is closely followed by Metoclopramide. More doctors working in the acute medical setting should be aware of the potential teratogenicity of drugs used to treat NVP.

ABSTRACT

Background: This literature review was devised to clarify the rationale between the use of
Dexamethasone and Prednisolone for the treatment of paediatric Croup in the community setting.
Methods: A computerised literature search of local and international Guidelines, PubMed and CENTRAL
(Cochrane Central Register of Controlled Trials) was carried out. Fifteen sources were included.
Indications and use of dexamethasone and prednisolone varied across the cited literature. An evidence
based practice viewpoint and appraisal of the literature was undertaken and the results collated.
Results: Analysis of the literature shows a clinical benefit of Dexamethasone in comparison to
Prednisolone when it comes to re-presentation, with a reduction in patient readmission and
re-presentation when using Dexamethasone compared to Prednisolone. Clinical benefit outside of this
parameter has not been proven. There was also a demonstrable effect on caregiver stress levels when
Dexamethasone was given compared to Prednisolone given ease of use. Some benefit with improved
tolerance with Dexamethasone compared to Prednisolone. There is also a potential cost benefit
involved in treating Croup with single dose Dexamethasone but this would need further exploration in
the New Zealand context.

Abstract:

Cannabinoid Hyperemesis Syndrome (CHS) is a syndrome of intractable vomiting with severe abdominal pain that is associated with chronic marijuana use. Classically, symptoms are relieved by hot showers and are often unresponsive to traditional acute interventions such as antiemetics.

Patients commonly undergo multiple investigations without diagnosis.  Complete resolution of symptoms occurs with abstinence from cannabis.

The following Medical Literature Project gives an overview of Cannabinoid Hyperemesis Syndrome and review of current management.

Abstract:

Paediatric forearm fractures are a common presentation seen in Urgent Care, often occurring from a fall onto an outstretched hand. Currently, best practice is for an x-ray when there is suspicion of a fracture.However, this comes with exposure to ionising radiation and can be associated with prolonged waiting times, pain, and further cost. This review aims to investigate whether point of care ultrasound (POCUS) could be used as an alternative or preferred option for suspected distal radius fractures in children.

Abstract:

A literature review was carried out to assess the safety of Adenosine in Urgent Care (UC) setting for the termination of Paroxysmal Supraventricular tachycardia (PSVT). Thorough literature evaluation advocates the use of adenosine for the acute termination of PSVT in Urgent care settings, especially in rural and remote practices. It has the potential to improve patient management and satisfaction along with a reduction in cost, ED load, and associated hospitalization.

Abstract:
Paediatric lateral condylar fractures (PLCF) are the most common fractures in children under the age of 7. This article will provide an overview of paediatric lateral condylar fractures with an emphasis on the importance of obtaining adequate radiographs and providing an accurate classification to guide management. It is essential for Urgent Care clinicians to be competent in the reading of paediatric elbow radiographs and possess a sound knowledge of the different classification systems of PLCF in order to provide the correct treatment and knowing when to refer for operative and non-operative treatment.
