Effect of the Dutch Hip Fracture Audit implementation on mortality, length of hospital stay and time until surgery in elderly hip fracture patients; a multi-center cohort study

Background: In 2040 the estimated number of people with a hip fracture in the Netherlands will be about 24,000. The medical care for this group of patients is complicated and challenging. Multidisciplinary approaches aim to improve clinical outcome. Quality indicators that gain insight in the treatment and outcome of hip fracture patients may help to optimize and monit

Follow-up period of 13 years after endoscopic total extraperitoneal repair of inguinal hernias: a cohort study

Background: Endoscopic inguinal hernia repair was introduced in the Netherlands in the early 1990s. The authors' institution was among the first to adopt this technique. In this study, long-term hernia recurrence among patients treated by the total extraperitoneal (TEP) approach for an inguinal hernia is described. A cohort study was conducted. Methods: Between January 1993 and December 1997, 346 TEP hernia repairs were performed for 318 patients. After a mean follow-up period of 13-years, a senior resident examined each patient. An experienced surgeon subsequently examined the patients with a diagnosis of recurrent hernia. Data were collected on an intention-to-treat basis, meaning that conversions were included in the analysis. Univariant tests were used to analyze age older than 50 years, chronic obstructive pulmonary disease, body mass index, smoking habit, hernia type, history of open hernia repair, conversion, and surgeon as potential risk factors. Results: The analysis included 191 patients (62%) with 213 hernias. Of the original 318 patients, 59 patients died, and 68 were lost to follow-up evaluation. Perioperatively, 105 lateral, 55 medial, and 53 pantalon hernias were observed. Of the 213 hernias, 176 were primary and 37 were recurrent. The overall recurrence rate was 8.9% (8.5% for primary and 10.8% for recurrent hernias). Of the total study group, 48% of the patients experienced a bilateral inguinal hernia during their lifetime. No predicting factor for recurrent hernia could be identified. Conclusions: The current long-term results for TEP repair of primary and secondary inguinal hernia show an overall recurrence rate of 8.9%, which is slightly higher than in previous studies. The thorough examination at follow-up assessment, the learning curve effect, and the intention-to-treat-analysis may have influenced the observed recurrence rate. Also, the percentage of bilateral hernias was higher than known to date. Therefore, examination of the contralateral side should be standard procedure

Safety and immunogenicity of rVSVΔG-ZEBOV-GP Ebola vaccine in adults and children in Lambaréné, Gabon: A phase I randomised trial.

BACKGROUND: The rVSVΔG-ZEBOV-GP vaccine prevented Ebola virus disease when used at 2 × 107 plaque-forming units (PFU) in a trial in Guinea. This study provides further safety and immunogenicity data. METHODS AND FINDINGS: A randomised, open-label phase I trial in Lambaréné, Gabon, studied 5 single intramuscular vaccine doses of 3 × 103, 3 × 104, 3 × 105, 3 × 106, or 2 × 107 PFU in 115 adults and a dose of 2 × 107 PFU in 20 adolescents and 20 children. The primary objective was safety and tolerability 28 days post-injection. Immunogenicity, viraemia, and shedding post-vaccination were evaluated as secondary objectives. In adults, mild-to-moderate adverse events were frequent, but there were no serious or severe adverse events related to vaccination. Before vaccination, Zaire Ebola virus (ZEBOV)-glycoprotein (GP)-specific and ZEBOV antibodies were detected in 11% and 27% of adults, respectively. In adults, 74%-100% of individuals who received a dose 3 × 104, 3 × 105, 3 × 106, or 2 × 107 PFU had a ≥4.0-fold increase in geometric mean titres (GMTs) of ZEBOV-GP-specific antibodies at day 28, reaching GMTs of 489 (95% CI: 264-908), 556 (95% CI: 280-1,101), 1,245 (95% CI: 899-1,724), and 1,503 (95% CI: 931-2,426), respectively. Twenty-two percent of adults had a ≥4-fold increase of ZEBOV antibodies, with GMTs at day 28 of 1,015 (647-1,591), 1,887 (1,154-3,085), 1,445 (1,013-2,062), and 3,958 (2,249-6,967) for the same doses, respectively. These antibodies persisted up to day 180 for doses ≥3 × 105 PFU. Adults with antibodies before vaccination had higher GMTs throughout. Neutralising antibodies were detected in more than 50% of participants at doses ≥3 × 105 PFU. As in adults, no serious or severe adverse events related to vaccine occurred in adolescents or children. At day 2, vaccine RNA titres were higher for adolescents and children than adults. At day 7, 78% of adolescents and 35% of children had recombinant vesicular stomatitis virus RNA detectable in saliva. The vaccine induced high GMTs of ZEBOV-GP-specific antibodies at day 28 in adolescents, 1,428 (95% CI: 1,025-1,989), and children, 1,620 (95% CI: 806-3,259), and in both groups antibody titres increased up to day 180. The absence of a control group, lack of stratification for baseline antibody status, and imbalances in male/female ratio are the main limitations of this study. CONCLUSIONS: Our data confirm the acceptable safety and immunogenicity profile of the 2 × 107 PFU dose in adults and support consideration of lower doses for paediatric populations and those who request boosting.

Vuurwerkletsel in Zuidwest-Nederland rond de jaarwisseling 2017-2018

OBJECTIVE: To report the number of patients with firework-related injuries treated in December 2017 and January 2018 in a hospital in the south-west Netherlands trauma region, and to provide details about the types of firework used and the specific injuries. DESIGN: A prospective multicentre cohort study (NTR6793). METHODS: Patients of all ages with firework-related injuries were eligible for inclusion. The injury had to have been sustained between 1 December 2017 and 31 January 2018, and treated at a hospital in the south-west Netherlands trauma region (approximately 2.5 million inhabitants). Data were extracted from patients' medical files and additional information was obtained from patient interviews. RESULTS: Fifty-four patients were included. The majority were male (93%) and the median age was 15 years. Twenty-five (46%) patients were bystanders and 12 (22%) were injured by illegal fireworks. Fifty patients were injured by bangers (n=22) or decorative fireworks (n=28). The patients had a total of 79 injuries, of which 29 (37%) were localised to the upper extremity and 19 (24%) to the eyes. Most upper extremity injuries were burns (69%), primarily partial thickness. Of the eye injuries, 14 were caused by blunt trauma, seven by chemical trauma, and one by penetrating trauma. Three patients sustained indirect firework-related injuries. CONCLUSION: Between 1 December 2017 and 31 January 2018 in the south-west Netherlands trauma region mainly teenage males and bystanders sustained firework-related injuries. Most injuries were upper extremity burns and eye injuries, mainly due to legal fireworks and bangers or decorative fireworks. The extent of the sample indicatDoel Een volledig overzicht geven van het aantal vuurwerkslachtoffers dat in december 2017 en januari 2018 behandeld werd in een ziekenhuis in de traumaregio Zuidwest-Nederland, het gebruikte soort vuurwerk en de specifieke letsels. Opzet Een prospectieve, multicentrische cohortstudie (NTR6793). Methode Patiënten van alle leeftijden met vuurwerkletsel kwamen in aanmerking voor inclusie. Het letsel moest zijn ontstaan in de periode 1 december 2017-31 januari 2018 en zijn behandeld in een ziekenhuis in de traumaregio Zuidwest-Nederland (circa 2,5 miljoen inwoners). Gegevens werden verzameld vanuit het patiëntendossier en aanvullende gegevens werden verkregen tijdens een interview. Resultaten Er werden 54 patiënten geïncludeerd. Het overgrote deel betrof mannen (93%) en de mediane leeftijd was 15 jaar. 25 gewonden (46%) waren omstander en 12 mensen (22%) raakten gewond door illegaal vuurwerk. Van de 54 patiënten raakten er 50 gewond door knalvuurwerk (n = 22) of siervuurwerk (n = 28). De 54 geïncludeerde patiënten hadden 79 letsels; het letsel was 29 keer (37%) gelokaliseerd aan armen of handen en 19 keer (24%) aan de ogen. Letsel aan de arm of hand bestond voornamelijk uit brandwonden (69%), met name tweedegraads. Oogletsel werd 14 keer door stomp inwerkend geweld veroorzaakt, 7 keer door chemisch letsel en 1 keer werd het oog gepenetreerd. Er raakten 3 patiënten indirect gewond door vuurwerk. Conclusie In de traumaregio Zuidwest-Nederland raakten in de 2 maanden rond de jaarwisseling 2017-2018 vooral minderjarige mannen en omstanders gewond. Slachtoffers liepen met name brandwonden aan armen of handen of oogletsel op. De verwondingen waren met name het gevolg van legaal knal- en siervuurwerk. Door de omvang van de steekproef lijken de studiebevindingen goed te extrapoleren naar het gehele land

A symptom-based algorithm for calcium management after thyroid surgery: a prospective multicenter study

Objective: Evidence-based treatment guidelines for the management of postthyroidectomy hypocalcemia are absent. The aim of this study was to evaluate a newly developed symptom-based treatment algorithm including a protocolized attempt to phase out supplementation. Methods: In a prospective multicenter study, patients were treated according to the new algorithm and compared to a historical cohort of patients treated with a biochemically based approach. The primary outcome was the proportion of patients receiving calcium and/or alfacalcidol supplementation. Secondary outcomes were calcium-related complications and predictors for supplementation. Results: One hundred thirty-four patients were included prospectively, and compared to 392 historical patients. The new algorithm significantly reduced the proportion of patients treated with calcium and/or alfacalcidol during the first postoperative year (odds ratio (OR): 0.36 (95% CI: 0.23–0.54), P < 0.001), and persistently at 12 months follow-up (OR: 0.51 (95% CI: 0.28–0.90), P < 0.05). No severe calcium-related complications occurred, even though calcium-related visits to the emergency department and readmissions increased (OR: 11.5 (95% CI: 4.51–29.3), P <0.001) and (OR: 3.46 (95% CI: 1.58–7.57), P < 0.05), respectively. The proportional change in pre- to post operative parathyroid hormone (PTH) was an independent predictor for supplementation (OR: 1.04 (95% CI: 1.02–1.07), P < 0.05). Conclusions: Symptom-based management of postthyroidectomy hypocalcemia and a protocolized attempt to phase out supplementation safely reduce d the proportion of patients receiving supplementation, although the number of calcium-related hospital visits increased. For the future, we envision a more individualized treatment approach for patients at risk for delayed symptomatic hypocalcemia, including the proportional change in pre- to post- operative PTH

Epidemiology of injuries, treatment (costs) and outcome in burn patients admitted to a hospital with or without dedicated burn centre (Burn-Pro)

INTRODUCTION: The Emergency Management of Severe Burns (EMSB) referral criteria have been implemented for optimal triaging of burn patients. Admission to a burn centre is indicated for patients with severe burns or with specific characteristics like older age or comorbidities. Patients not meeting these criteria can also be treated in a hospital without burn centre. Limited information is available about the organisation of care and referral of these patients. The aims of this study are to determine the burn injury characteristics, treatment (costs), quality of life and scar quality of burn patients admitted to a hospital without dedicated burn centre. These data will subsequently be compared with data from patients with<10% total bodysurface area (TBSA) burned who are admitted (or secondarily referred) to a burn centre. If admissions were in agreement with the EMSB, referral criteria will also be determined. METHODS AND ANALYSIS: In this multicentre, prospective, observational study (cohort study), the following two groups of patients will be followed: 1) all patients (no age limit) admitted with burn-related injuries to a hospital without a dedicated burn centre in the Southwest Netherlands or Brabant Trauma Region and 2) all patients (no age limit) with<10% TBSA burned who are primarily admitted (or secondarily referred) to the burn centre of Maasstad Hospital. Data on the burn injury characteristics (primary outcome), EMSB compliance, treatment, treatment costs and outcome will be collected from the patients' medical files. At 3 weeks and at 3, 6 and 12 months after trauma, patients will be asked to complete the quality of life questionnaire (EuroQoL-5D), and the patient-reported part of the Patient and Observer Scar Assessment Scale (POSAS). At those time visits, the coordinating investigator or research assistant will complete the observer-reported part of the POSAS. ETHICS AND DISSEMINATION: This study has been exempted by the medical r

A 10-year follow-up study on endoscopic total extraperitoneal repair of primary and recurrent inguinal hernia

Background To determine whether endoscopic repair is favorable in the long term, follow-up recurrence rates afrter 10 years need to be assessed. Methods Between January 1995 and January 1996, 306 consecutive patients underwent total extraperitoneal (TEP) inguinal hernia repair. Long-term follow-up assessment occurred from January 2006 to May 2006. Results After a 10-year follow-up period, six (4%) recurrences were found in the primary inguinal hernia group and three recurrences (11%) in the recurrent inguinal hernia group. Age, experience, hospital stay, and operating time were not significantly correlated with recurrences. Conclusion The long-term results of TEP primary inguinal hernia repair demonstrate it to be an effective and safe procedure with an acceptable recurrence rate. Recurrence rates may be underestimated because the findings show that recurrences continue to occur for as long as 10 years

Evaluation of a shared decision-making strategy with online decision aids in surgical and orthopaedic practice: study protocol for the E-valuAID, a multicentre study with a stepped-wedge design

Contains fulltext : 232427.pdf (Publisher’s version ) (Open Access)BACKGROUND: Inguinal hernia repair, gallbladder removal, and knee- and hip replacements are the most commonly performed surgical procedures, but all are subject to practice variation and variable patient-reported outcomes. Shared decision-making (SDM) has the potential to reduce surgery rates and increase patient satisfaction. This study aims to evaluate the effectiveness of an SDM strategy with online decision aids for surgical and orthopaedic practice in terms of impact on surgery rates, patient-reported outcomes, and cost-effectiveness. METHODS: The E-valuAID-study is designed as a multicentre, non-randomized stepped-wedge study in patients with an inguinal hernia, gallstones, knee or hip osteoarthritis in six surgical and six orthopaedic departments. The primary outcome is the surgery rate before and after implementation of the SDM strategy. Secondary outcomes are patient-reported outcomes and cost-effectiveness. Patients in the usual care cluster prior to implementation of the SDM strategy will be treated in accordance with the best available clinical evidence, physician's knowledge and preference and the patient's preference. The intervention consists of the implementation of the SDM strategy and provision of disease-specific online decision aids. Decision aids will be provided to the patients before the consultation in which treatment decision is made. During this consultation, treatment preferences are discussed, and the final treatment decision is confirmed. Surgery rates will be extracted from hospital files. Secondary outcomes will be evaluated using questionnaires, at baseline, 3 and 6 months. DISCUSSION: The E-valuAID-study will examine the cost-effectiveness of an SDM strategy with online decision aids in patients with an inguinal hernia, gallstones, knee or hip osteoarthritis. This study will show whether decision aids reduce operation rates while improving patient-reported outcomes. We hypothesize that the SDM strategy will lead to lower surgery rates, better patient-reported outcomes, and be cost-effective.
