ABSTRACT

BACKGROUND: Acute appendicitis is a common surgical emergency that is typically managed with laparoscopic appendicectomy in UK centres. A number of variables influence the cost of managing this condition. Our aim was to identify the major influencing factors in our centre by performing a cumulative cost analysis. METHODS: We retrospectively analysed the costs associated with 99 cases of acute appendicitis managed with laparoscopic appendicectomy at Ninewells Hospital, Dundee, from January 2014 to February 2016. Costs were categorised according to blood tests, imaging, medications, operative costs and length of stay. RESULTS: Our cohort included 66 males, 33 females and 28 paediatric cases. The total cost was £220030.52 with a mean of £2222.53 per patient. The factor with the greatest influence on overall cost was operative time (53.2%) followed by length of stay (39.2%). There was no cost difference between adults and children (p = 0.24) or males and females (p = 0.38). Mean cost in adults ≥50 years was greater than those <50 years (£2899.32 vs £2152.97, p = 0.008) and greater in those who underwent imaging as opposed to no imaging (£2789.53 vs £2010.65, p = 0.0001). For appendiceal stump technique, polymer clips were cheaper (£1844.70) than ligatures (£2380.11, p = 0.006). CONCLUSIONS: Operative time (53.2%) and length of stay (39.2%) had the greatest impact on the cost in our cohort. Older patients have a greater overall cost, and this is associated with increased utilisation of imaging. Further studies assessing the safety and feasibility of methods to reduce operative time and to investigate the safety of reducing length of stay are required.

ABSTRACT

Background: Inguinal hernias are common in less economically developed countries (LEDCs), and associated with significant morbidity and mortality. Tension-free mesh repair is the standard treatment worldwide. Lack of resources combined with the high cost of commercial synthetic mesh (CSM) have limited its use in LEDCs. Sterilized mosquito net mesh (MNM) has emerged as a low-cost, readily available alternative to CSM. The aim of this systematic review and meta-analysis was to evaluate the safety and efficacy of MNM for the use in hernia repair in LEDCs. Methods: A systematic review and data meta-analysis of all published articles from inception to August 2018 was performed. Cochrane Central Register of Controlled Trials, MEDLINE and Embase databases were searched. The primary outcome measure was the overall postoperative complication rate of hernia repair when using MNM. Secondary outcome measures were comparisons between MNM and CSM with regard to overall complication rate, wound infection, chronic pain and haematoma formation. Results: A total of nine studies were considered relevant (3 RCTs, 1 non-randomized trial and 5 prospective studies), providing a total cohort of 1085 patients using MNM. The overall complication rate for hernia repair using MNM was 9·3 per cent. There was no significant difference between MNM and CSM regarding the overall postoperative complication rate (odds ratio 0·99, 95 per cent c.i. 0·65 to 1·53; P = 0·98), severe or chronic pain (OR 2·52, 0·36 to 17·42; P = 0·35), infection (OR 0·56, 0·19 to 1·61; P = 0·28) or haematoma (OR 1·05, 0·62 to 1·78; P = 0·86). Conclusion: MNM has a low overall postoperative complication rate and is unlikely to be inferior to CSM in terms of safety and efficacy. MNM is a suitable low-cost alternative to CSM in the presence of financial constraint.

ABSTRACT

AIMS: Intravenous (IV) fluid administration continues to be a mainstay of care in General Surgery. Yet if they are prescribed incorrectly significant morbidity including electrolyte abnormalities, renal impairment and cardiac failure can develop. Despite this, it is frequently the responsibility of the most junior staff to prescribe IV fluids. We aim to analyse the understanding of IV fluid prescribing amongst junior doctors and to describe variability in clinical practice. METHODS: We undertook a multicentre questionnaire study. Foundation doctors and specialty trainees were invited to undertake a two part paper-based questionnaire. Part one analysed baseline knowledge of the concentration of commonly prescribed fluids. Part two consisted of four clinical vignettes requiring a IV fluid prescribing decision by the surveyed doctor. RESULTS: A total of 143 Doctors working in 8 hospitals were recruited. 65 (45.5%) doctors correctly stated the daily maintenance fluid requirements of water for an adult (25-30 mls/kg/day), while only 54 (37.8%) knew the sodium concentration of 0.9% NaCl. Lack of postgraduate experience (p = 0.011), qualifying from a medical school outside the United Kingdom (p < 0.0001) and working in one of the eight hospitals in this study (p < 0.0001) were associated with a lower knowledge level. There was limited consensus in prescribing in the responses to the 4 clinical scenarios, with 69 unique combinations of fluid choice, rate and volume prescribed. CONCLUSIONS: Knowledge of the constituents of common IV fluids and routine requirement for fluid and common electrolytes is poor across junior doctors of all grades, driving large variation in clinical practice.

ABSTRACT

Metformin is an effective and commonly administered drug for controlling plasma glucose concentrations in patients with type 2 diabetes mellitus. Gastrointestinal adverse effects such as abdominal pain, nausea, dyspepsia, anorexia, and diarrhea are common and widely accepted when occurring at the start of metformin therapy. Diarrhea occurring long after the dosage titration period is much less well recognized. Our patient began to experience nausea, abdominal cramping, and explosive watery diarrhea that occasionally caused incontinence after several years of stable metformin therapy A trial of metformin discontinuation resolved all gastrointestinal symptoms. A review of the literature revealed two reports that suggest diarrhea occurring long after the start of metformin therapy is relatively common, based on surveys of patients with diabetes. Metformin-induced diarrhea is differentiated from diabetic diarrhea, which is clinically similar, except diabetic diarrhea is rare in patients with type 2 diabetes. Patients with type 2 diabetes who are taking metformin and experience diarrhea deserve a drug-free interval before undergoing expensive and uncomfortable diagnostic tests, even when the dosage has been stable over a long period.

ABSTRACT

Nine hundred Tennessee-based internists, family physicians, and obstetrician-gynecologists were randomly selected and surveyed to identify Papanicolaou smear cell recovery methods used in their practices. This 16-item survey also requested typical laboratory reporting procedures on Papanicolaous smears. The most frequently reported cell sampling technique was the combination cotton-tipped applicator and spatula, which was used by 47 percent of all physicians. Use of the cervical cytobrush for Papanicolaou smears, which has been shown to improve the detection of cervical dysplasia, was used alone or in combination by 19 percent of those surveyed, of whom 72 percent were gynecologists. Cervical sampling should contain cells from the transformation zone as evidenced by an adequate number of endocervical cells on the smear. Laboratories reporting the presence of endocervical cells were significantly different (P less than 0.05) among the specialties, with 26 percent of the internists', 18 percent of the family physicians', and 15 percent of the obstetricians' laboratories not providing this information in their reports. Reporting inadequate smears is a necessary first step toward improved sampling technique. Without this information, physicians risk missing pathology through reports of false-negative Papanicolaou smears.
