Prescribing of antivirals for COVID-19 in a South Australian local health network according to statewide guidelines.

Antiviral drugs were rapidly implemented into clinical practice for the treatment of high-risk patients with COVID-19, prompting the development of statewide guidelines. This South-Australian study reviewed guideline adherence, assessed prescribing patterns and highlighted the inappropriate management of relative drug-drug interactions and dosing for renal function. Additionally, it evaluated the impact of inappropriate antiviral drug use and suggested methods to improve quality use of medicines.

The Clinical Impact of Hospital-Acquired Adverse Drug Reactions in Older Adults: An Australian Cohort Study.

INTRODUCTION: Hospital-acquired adverse drug reactions (HA-ADRs) are common in older adults. However, there is limited knowledge regarding the association between HA-ADRs and adverse clinical outcomes. OBJECTIVE: To investigate the incidence and characteristics of HA-ADRs in older adults, and any association with mortality, length of stay, and readmissions. DESIGN: Prospective cohort study. SETTING AND PARTICIPANTS: Flinders Medical Centre, a large tertiary referral hospital in Adelaide, South Australia. Older adults admitted under the General Medicine and Acute Care of the Elderly units with no previous diagnosis of dementia. METHODS: All patients had a Multidimensional Prognostic Index (MPI) assessment performed within 3 days of the admission. Data collected included age, gender, estimated glomerular filtration rate (eGFR), length of stay, readmissions, and mortality. HA-ADRs were identified by review of individual discharge summaries. Univariate and multivariate analyses were performed to investigate associations with clinical outcomes including mortality, length of stay, and readmissions. Exploratory analyses were performed for HA-ADR groups based on Medical Dictionary for Regulatory Activities System Organ Class and World Health Organization Anatomical Therapeutic Chemical classifications that accounted for ≥10% of all HA-ADRs. RESULTS: There were 737 patients in the cohort with 72 having experienced a HA-ADRs (incidence = 9.8%). Patients with an HA-ADR had increased length of stay and 30-day readmissions compared with those without an HA-ADR. In multivariate analysis, the number of HA-ADRs was associated with in-hospital mortality and length of stay but not post-discharge mortality or readmissions within 30 days. In exploratory analyses, patients with an HA-ADR to antibacterial drugs had significantly higher rates of in-hospital mortality compared with those without these reactions. CONCLUSIONS AND IMPLICATIONS: The number of HA-ADRs are associated with in-hospital mortality and length of stay in older Australian inpatients. The occurrence of HA-ADRs may be a trigger to offer advice to prescribers to prevent future ADRs to similar agents and proactively manage disease to improve health outcomes.

Metabolic and Nutritional Issues after Lower Digestive Tract Surgery: The Important Role of the Dietitian in a Multidisciplinary Setting.

Many patients undergo small bowel and colon surgery for reasons related to malignancy, inflammatory bowel disease (IBD), mesenteric ischemia, and other benign conditions, including post-operative adhesions, hernias, trauma, volvulus, or diverticula. Some patients arrive in the operating theatre severely malnourished due to an underlying disease, while others develop complications (e.g., anastomotic leaks, abscesses, or strictures) that induce a systemic inflammatory response that can increase their energy and protein requirements. Finally, anatomical and functional changes resulting from surgery can affect either nutritional status due to malabsorption or nutritional support (NS) pathways. The dietitian providing NS to these patients needs to understand the pathophysiology underlying these sequelae and collaborate with other professionals, including surgeons, internists, nurses, and pharmacists. The aim of this review is to provide an overview of the nutritional and metabolic consequences of different types of lower gastrointestinal surgery and the role of the dietitian in providing comprehensive patient care. This article reviews the effects of small bowel resection on macronutrient and micronutrient absorption, the effects of colectomies (e.g., ileocolectomy, low anterior resection, abdominoperineal resection, and proctocolectomy) that require special dietary considerations, nutritional considerations specific to ostomized patients, and clinical practice guidelines for caregivers of patients who have undergone a surgery for local and systemic complications of IBD. Finally, we highlight the valuable contribution of the dietitian in the challenging management of short bowel syndrome and intestinal failure.

Recent developments in enteral feeding for adults: an update.

In the 1980s, enteral nutrition became increasingly recognised as a safe, effective and cost-efficient method of providing nutrition to patients with a functional gut (Silk, 2003). With this came the development of feeding-specific nasogastric (NG) tubes (Rees et al, 1986) and the formulation of nutritionally complete, ready-to-hang feeds (Keohane et al, 1983), as well as the creation of gastrostomy tubes for direct access to the stomach by Ponsky and Gauderer (1981) followed by jejunostomys 11 years later (Shike et al, 1991). Since then there have been many developments in every aspect of enteral feeding, with over 30 enteral feeds listed in the British National Formulary (BNF) (Joint Formulary Committee, 2012) and companies continually designing new tubes that are smaller or more comfortable and feeding pumps that are quieter and easier to use. This article discusses the developments in enteral feeding over the last 5 years to give the reader an update on current topics and issues in enteral feeding.

Nutrition for wound healing.

The importance of the role of nutrition in wound healing is an area that has been widely explored over the last decade. It is well recognised that both macronutrients (protein, fat and carbohydrate) and micronutrients (vitamins, minerals and trace elements) play important parts in the healing of both chronic wounds and acute injuries. The term 'wound' encompasses many different situations from leg ulcers to laparostomy wounds. This article provides an overview of the role of different nutrients in the healing of wounds and guidance to nurses on first-line assessments, which can be used to ensure the patient is receiving adequate nutrition for successful wound healing. It will focus on commonly seen wounds in primary and secondary care but will not cover specialist wound management, such as laparostomy sites and burns, as these must always be cared for by experienced and specialist multidisciplinary teams.

Nutritional and fluid requirements: high-output stomas.

Based on the current available evidence, this article explores the nutritional management of those with a high-output stoma. The main alterations required to the intake of patients with a high-output stoma include the use of an oral rehydration solution to ensure optimum absorption of fluid and sodium, and a high-calorie, high-protein diet, with the aim of optimizing nutritional status. Diet advice should be delivered by a dietitian with experience in managing these complex patients. Monitoring of electrolytes and micronutrients is essential, and long-term follow up from a multidisciplinary nutrition support team is invaluable in coordinating this. Patients with high-output stomas can enjoy good quality of life and long-term health if their condition is managed effectively by a well-organized multidisciplinary team.
