Orthogeriatric co-management – managing frailty as well as fragility

A high proportion of patients with fragility fracture, mainly hip fracture, have a variable degree of comorbidity and show some degree of dependence in basic or more complex activities of daily living. Evaluating these patents following the geriatric concept of frailty, about one third of hip fracture patients may be categorised as frail with high risk of poor outcomes and prolonged length of stay, one third as not frail, and about one third with an intermediate condition. Due to the high vulnerability, combined with the hip fracture event and surgical repair procedures, a multidisciplinary approach that includes geriatric competencies becomes essential to improve short and long-term outcomes after hip fracture. A key element of an effective process of care is a true co-managed approach that applies quality standards and provides a fast-track pathway of care, minimises the time the patient spends in bed, and reduces postoperative complications by means of standardised procedures.The occurrence of a fragility fracture is the strongest risk factor for a subsequent fracture. Moreover, frail subjects have a further risk of fracture due to high risk of falls − related to loss of muscle mass, multiple illnesses, impaired balance and weakness. Thus, effective secondary prevention strategies are essential to reduce morbidity and mortality after hip fracture, and they are currently a standard task of orthogeriatric care. Fracture liaison services (FLS) are probably the most efficient way of addressing secondary prevention including the assessment of both bone health and falls risk. Therefore, the optimal management of frail patients with fragility fracture includes both orthogeriatric care and FLS, which are complementary to each other.Orthogeriatric collaboration is also powerful in influencing healthcare policy. British experience as well as that in Ireland, Australia and New Zealand, have shown that when two widely disparate specialisms say the same thing, they may achieve a fundamental shift in attitudes and behaviour of both managers and clinicians. Furthermore, a continuous real-time audit, at national level, is a powerful driver for change and better standards of care.     

Is laparoscopic colectomy as cost beneficial as open colectomy?

Background: Laparoscopic colectomy has yet to gain widespread acceptance in cost‐conscious health‐care institutions. The aim of the present study was to define the cost–benefit relationship of laparoscopic versus open colectomy. Methods: Thirty‐two consecutive patients undergoing elective laparoscopic colectomy (LC) by a single colorectal surgeon between August 2004 and September 2005 were reviewed. Cases were matched with a historical cohort undergoing elective open colectomy (OC) between June 2003 and July 2004. Demography, perioperative data, histopathology and cost were compared. Results: Both groups had similar demographics. Most resections (90.6%) were for cancer. Operative time was significantly longer for LC compared to OC (180 min vs 110 min, P < 0.001). Four patients (12.5%) in the LC group required conversion. LC patients, however, had lower median pain scores (3, 2 and 1 vs 6, 4 and 2 at 24, 48 and 72 h postoperatively, P < 0.001), faster resolution of ileus (3 vs 4 days, P < 0.001) and earlier discharge (6 vs 9 days, P < 0.001) compared to the OC group. As a result, overall hospital cost for both procedures was not significantly different (US$7943 vs US$7253, P = 0.41). Conclusion: Laparoscopic colectomy is as cost‐beneficial in the short term as open colectomy.     

Perioperative on-site haemoglobin determination: as accurate as laboratory values?

Purpose

This study assessed the accuracy of photometer based haemoglobin (Hb) determination technology (HemoCue®) when used by different anaesthetists in situations of rapidly changing Hb values during anaesthesia.

Methods

(Part 1) In the laboratory, repeated measurements were done on 16 split samples of blood using both the Hematology Analyzer (CELLDYN 3500 System?, Abbot Laboratories, San Jose, California) and the photometer. (Part 2) Twelve patients had blood samples drawn from an arterial line for simultaneous Hb determination in the hospital laboratory and by the photometer. At the same time, capillary samples were taken from the patient’s earlobe for Hb determination by the photometer. All sample collection and photometer measurements were done by the same operator. (Part 3) The Part 2 protocol was then repeated with different anaesthetists performing both the sampling and the photometer measurements. Statistical comparison was by ANOVA and a twotailed paired ttest.

Results

(Part 1) Samples determined by the photometer and the laboratory were highly correlated (r² = 1.0, P < 0.001). The average error of each method was similar (< 4%). (Part 2) Using a 2-tailed paired ttest, the photometer arterial measurements were not different from the laboratory measurements, however the photometer capillary measurements were consistently ≈8% higher (P = 0.003). (Part 3) When multiple operators performed the sampling there were no differences on arterial or capillary samples (r² = 0.942, r² = 0.851 respectively), although the variance was greater.

Conclusions

The HemoCue® haemoglobinometer has sufficient accuracy to support treatment decisions regarding blood transfusions.     

Are we really as good as we think we are?

Differences are examined in assessment and self-assessment scores, in oral and maxillofacial surgery trainees and MSc postgraduates, following the surgical removal of lower third molar teeth. This study found evidence of a surprising and worrying over-rating of their own surgical skills by many trainees and postgraduates.     

Is non-biological treatment of rheumatoid arthritis as good as biologics?

The management of rheumatoid arthritis (RA) in the past three decades has undergone a paradigm shift from symptomatic relief to a “treat-to-target” approach. This has been possible through use of various conventional and biologic disease modifying anti-rheumatic drugs (DMARDs) which target disease pathogenesis at a molecular level. Cost and infection risk preclude regular use of biologics in resource-constrained settings. In the recent years, evidence has emerged that combination therapy with conventional DMARDs is not inferior to biologics in the management of RA and is a feasible cost-effective option.     

The Gastric Sleeve: Losing Weight as Fast as Micronutrients?

Background  

Recently, the laparoscopic sleeve gastrectomy (LSG) has become popular as a single-stage procedure for the treatment of morbid obesity and its co-morbidities. However, the incidence of micronutrient deficiencies after LSG have hardly been researched.     

Do residents perform TKAs using computer navigation as accurately as consultants?

The implantation of a total knee arthroplasty (TKA) is a milestone in a resident's surgical training. Studies demonstrate higher loosening rates after TKA by inexperienced surgeons. Alignment outliers should be avoided to achieve a long implant survival. Therefore, our study questioned whether residents implant knee prostheses using computer navigation as accurately as experienced consultants. The data for 662 consecutive TKAs were analyzed retrospectively. The operations were performed by 4 consultants (n=555) and 5 residents under supervision by a consultant (n=107). Cutting errors were recorded from the navigation data. The postoperative mechanical axis and operation time were recorded. Operation time was significantly prolonged if residents performed the operation vs consultants (139 vs 122 minutes, respectively). The analysis of cutting errors within each surgeon's first 20 navigated operations resulted in no significant difference between residents and consultants. During the subsequent operations, a trend toward a more accurate placement of the prosthesis was detected for consultants. The rate of outliers with a mechanical axis deviation >2° was low and did not significantly differ between residents and consultants (3.7% vs 2.3%, respectively). Our study shows that residents implant their first TKA using computer navigation as accurately as experienced consultants. However, the residents' operations take longer and therefore incur additional costs for the teaching clinic.     

Are African–Americans as Successful as Caucasians after Laparoscopic Gastric Bypass?

Background Laparoscopic Roux-en-Y gastric bypass (LRYGBP) has been demonstrated to provide weight loss comparable to open gastric bypass. It has been suggested that African–Americans (AA) are not as successful as Caucasians (CA) after bariatric surgery. Our hypothesis was that AAs are just as successful as CA after LRYGBP in terms of weight loss and comorbidity improvement. Methods A retrospective chart review was performed on all AA and CA patients who underwent LRYGBP for a 6-month period. Success after LRYGBP [defined as (1) 25% loss of preoperative weight, (2) 50% excess weight loss (EWL), or (3) weight loss to within 50% ideal weight] was compared by ethnicity. Results 102 patients were included in this study. 97 patients (30 AA patients and 67 CA patients) had at least 1-year follow-up data available. Preoperative data did not differ between both groups. There was a statistically significant difference in %EWL between AA and CA (66% vs 74%; P < 0.05). However, there was no ethnic difference in the percentage of patients with successful weight loss (as defined by any of the above 3 criteria). Furthermore, there was no statistical difference between the percentages of AA and CA patients who had improved or resolved diabetes and hypertension. Conclusions LRYGBP offers good weight loss in all patients. While there may be greater %EWL in CA patients, no ethnic difference in successful weight loss exists. More importantly, co-morbidities improve or resolve equally between AA and CA patients. LRYGBP should be considered successful in AA patients.
