Achilles tendon rupture (ATR) is a common sports injury, with a rising incidence and significant impairments. Due to the lack of treatment guidelines, there is no consensus about diagnostic methods, primary treatment (non-surgical or surgical) and rehabilitation. It is hypothesized that this lack of consensus and guidelines leads to sub-optimal recovery and higher societal costs. The primary aim of this study is to give a broad insight into the recovery after ATR. Secondarily this study aims to explore factors contributing to recovery and gain insight into the cost-effectiveness of ATR management. This multicenter prospective cohort study will include all adult (≥ 18 years) patients with an ATR treated at the three main hospitals in the Northern Netherlands: University Medical Center Groningen, Martini Hospital Groningen and Medical Center Leeuwarden. All subjects will be invited for three visits at 3, 6 and 12 months post-injury. The following data will be collected: patient-reported outcome measures (PROMs), physical tests, imaging and economic questionnaires. At 3 months post-injury personal, injury, and treatment data will be collected through a baseline questionnaire and assessment of the medical file. The PROMs concern the Dutch version of the Achilles Tendon Total Rupture Score, EQ-5D-5 L, Oslo Sport Trauma Research Center Overuse Injury Questionnaire, Injury Psychological Readiness Return to Sport Scale, Tampa Scale of Kinesiophobia, Expectations, Motivation and Satisfaction questionnaire and a ranking of reasons for not returning to sport. The administered physical tests are the heel-rise test, standing dorsiflexion range of motion, resting tendon length and single leg hop for distance. Ultrasound Tissue Characterization will be used for imaging. Finally, economic data will be collected using the Productivity Cost Questionnaire and Medical Consumption Questionnaire. This prospective cohort study will contribute to optimal decision making in the primary treatment and rehabilitation of ATRs by providing insight into (1) ATR recovery (2) novel imaging for monitoring recovery (3) (barriers to) return to sport and (4) cost-effectiveness of management. The analysis of these data strives to give a broad insight into the recovery after ATR as well as provide data on novel imaging and costs, contributing to individualized ATR management.

AimThis prospective cohort study was performed to evaluate the impact of complications on quality of life (QOL) in colorectal surgery. The Clavien–Dindo complication classification (CDCC) is promising, but has not been evaluated by relating the classification to patient-reported outcome measures.MethodPatients undergoing colorectal surgery were evaluated prospectively 12 months postoperatively using the WHOQOL-BREF questionnaire. Patient data were prospectively recorded and complications were classified using the CDCC. Postoperative QOL in patients with minor and severe complications and patients without complications was compared using a general linear model. Relationships between CDCC and QOL were examined using correlations and multivariate regression.ResultsOf 218 patients, 130 (59.6%) had complications. In patients with severe complications there was a greater decrease in overall QOL (P = 0.043), QOL-physical (P < 0.001) and QOL-psychological (P = 0.013) domains in the first six postoperative weeks, whereas patients with minor complications had QOL scores comparable to those of patients without complications. QOL recovered to preoperative levels in all groups at 12 months. Change in QOL at 6 weeks was significantly correlated with CDCC grade, especially in the physical domain (Spearman's rho −0.287, P < 0.001). The presence of severe complications was an independent predictor of overall QOL, QOL-physical and QOL-psychological at 6 weeks.ConclusionSevere complications are associated with reduced postoperative QOL at 6 weeks, but QOL recovers after 12 months. CDCC grade negatively correlates with change in QOL in the early postoperative period. These findings support the theoretical framework of the CDCC.

PurposeThe purpose of this study was to evaluate the impact of complications following colorectal surgery on anxiety, depressive symptoms, and health status. Previously, very few studies examined the psychological impact of complications following colorectal surgery. Also, in clinical practice, little attention is paid to the psychological impact of complications.MethodsPatients undergoing colorectal surgery were evaluated prospectively preoperatively and postoperatively at 3 days, 6 weeks, and 1 year, using the Center for Epidemiological Studies-Depression (CES-D), State-Trait Anxiety Inventory (STAI), and Short Form 36 (SF-36) questionnaires. Patient data and complications were prospectively recorded. Postoperative CES-D, STAI, and SF-36 scores in patients with minor and severe complications were compared to scores of patients without complications using a general linear model.ResultsOf 218 patients, 130 (59.6 %) had complications. Colorectal surgery significantly increased depressive symptoms and anxiety levels in the same amount in all patient subgroups. Furthermore, it also lowered all domains of health status in all patient subgroups, but not equally. Patients with a severely complicated postoperative course had a larger postoperative decrease in health status, most notably at 6 weeks postoperatively with the largest effects in the physical-, mental-, social-, and vitality domains compared with the other subgroups.ConclusionsColorectal surgery has a profound effect on depressive and anxiety symptoms, as well as nearly all domains of health status. Occurrence of severe complications increases the negative effect of colorectal surgery on most domains of health status but do not specifically increase depressive symptoms or anxiety levels. At 6 weeks, these effects are most notable, but at 1 year, they have faded.Keywords: Health status, Anxiety, Depression, Colorectal surgery, Complications

Objective: The purpose of this retrospective cohort study was to investigate whether current practice where residents perform appendectomies affects quality of care. Therefore, we investigated whether there was a difference in incidence of complications and mortality in appendectomies performed by surgeons (S), supervised residents (SR), or unsupervised residents (UR). Background: Appendicitis is among the most frequent conditions requiring urgent surgery. Admittance and surgery are often managed by residents. Recent studies have shown that laparoscopic appendectomy can be safely performed by residents. It is not known whether these results are applicable on appendectomies in general. Methods: All patients undergoing appendectomy in our hospital between January 1, 2000, and December 31, 2009, were included in the analysis. Patients undergoing appendectomy by surgeons, supervised residents, and unsupervised residents were compared. Primary endpoints were complications and mortality. Results: During the study period, 1538 patients were operated. The risk of complications (S: 20% vs SR: 17% vs UR: 16%; P = 0.209, S vs SR; P = 0.149, S vs UR; andP = 0.872, SR vs UR) and mortality (S: 0.3% vs SR: 0.2% vs UR: 0.4%, P = 1.000 for all comparisons) were similar in all groups. In the multivariate model, the odds ratio for complications in the group operated by supervised residents was 0.84 (95% CI: 0.58–1.22, P = 0.357) versus 0.81 (95% CI: 0.55–1.18, P = 0.265) in the unsupervised residents’ group. Conclusions: Current practice where residents perform appendectomies either unsupervised or supervised by an experienced surgeon should not be discouraged. We found that it is safe and does not lead to more complications or negatively affect quality of care. (Ann Surg 2012;255:715–719)

Hospital complications can pose a threat to patients, contribute to higher mortality and morbidity, and increase both the average length of hospital stay (LOS) and the use of other resources. The purpose of this study is to express the relationship between complications and the use of hospital resources in financial parameters.All trauma patients admitted to the surgical ward in the period 2000 to 2008 were analyzed (n = 4,377). All activities registered during admission were obtained. The integral in-hospital cost prices of each activity were divided into various product groups. Median and interquartile ranges were presented for the number of activities in the product groups, stratified by age and Injury Severity Score. The relationship between both institutional- and trauma-related complications and the number of activities in the different product groups was tested with linear regression analysis with adjustment for confounding.Significant associations between trauma-related complications and LOS, therapeutic paramedical products, diagnostic radiologic products, other diagnostic products, diagnostic laboratory products, therapeutic surgical procedures, other therapeutic products, and total costs (β = 5,420; 95% confidence interval, 4,912-5,929) were found. Significant associations between institutional-related complications and LOS, therapeutic paramedical products, diagnostic radiologic products, therapeutic surgical procedures, and other therapeutic products were found. Total costs (β = 170; 95% confidence interval, -760 to 1,099) showed a nonsignificant association with institutional-related complications.Complications increase hospital costs, and even a small reduction in the number of complications will result in a substantial hospital cost savings and a reduction in the emotional and physical burdens of patients.

Background Because the death rate among the total trauma population is low, other performance indicators in addition to the classical dependent variable mortality are required to assess the overall quality of trauma care. The aim of this study was to develop and validate a prediction model for the occurrence of complications that can be used to adjust a measure of quality of trauma care for case mix. Methods Complications recorded in a trauma registry between 1997 and 2008 were analysed. Formulas for different types of complication (institution- or diagnosis-related) derived from logistic regression models were used to calculate the probability of absence of complications (PAC). Discriminative power was tested by calculating the area under the receiver operating characteristic curve (AUC) in test and validation samples. Calibration was tested using Hosmer and Lemeshow methodology. Results Some 5944 surgical trauma admissions were included in the analysis. A significant association between both institution- and diagnosis-related complications and Injury Severity Score was found. Diagnosis-related complications were also associated with Glasgow Coma Score and age. The AUCs of the PACs for institution- and diagnosis-related complications were 0·64 and 0·75 respectively in the test sample, and 0·66 and 0·76 in the validation sample. The AUCs increased when the outcomes of the models were divided into subcategories of complications. Hosmer and Lemeshow tests were not significant for all models, except that for institutional complications. Conclusion To predict complications, a distinction should be made between institution- and diagnosis-related complications. The development of more detailed diagnosis-related prediction models is preferable because of better performance. The formulas predicting the PAC can be used to compare expected and observed complications.

OBJECTIVE—To evaluate the discriminative power of the Diabetic Neuropathy Symptom (DNS) and Diabetic Neuropathy Examination (DNE) scores for diagnosing diabetic polyneuropathy (PNP), as well as their relation with cardiovascular autonomic function testing (cAFT) and electro-diagnostic studies (EDS). RESEARCH DESIGN AND METHODS—Three groups (matched for age and sex) were selected: 24 diabetic patients with neuropathic foot ulcers (DU), 24 diabetic patients without clinical neuropathy or ulcers (DC), and 21 control subjects without diabetes (C). In all participants, the DNS and DNE scores were assessed and cAFT (heart rate variability [HRV], baroreflex sensitivity [BRS]), and EDS were performed (Nerve Conduction Sum [NCS] score; muscle fiber conduction velocity: fastest/slowest ratio [F/S ratio]). RESULTS—Both the DNS and the DNE scores discriminated between the DU and DC groups significantly (P < 0.001). The DNE score even discriminated between DC and C (P < 0.05). Spearman’s correlation coefficients between both DNS and DNE scores and cAFT (HRV −0.42 and −0.44; BRS −0.30 and −0.29, respectively) and EDS (NCS 0.51 and 0.62; F/S ratio 0.44 and 0.62, respectively) were high. Odds ratios were calculated for both DNS and DNE scores with cAFT (HRV 4.4 and 5.7; BRS 20.7 and 14.2, respectively) and EDS (NCS 5.6 and 16.8; F/S ratio 7.2 and 18.8, respectively). CONCLUSIONS—The DNS and DNE scores are able to discriminate between patients with and without PNP and are strongly related to cAFT and EDS. This further confirms the strength of the DNS and DNE scores in diagnosing diabetic PNP in daily clinical practice.

Complications in surgery are an important cause of morbidity and mortality and may result in an increased length of stay in hospital, repeat surgery, additional medical treatment, legal issues and increased costs.1–5 Apart from mortality, complications are among the most frequently measured and reported outcomes used to evaluate surgical treatment.6 They are used as an indicator of quality, and their continuous evaluation can identify possible flaws in the process of care. Although efforts are being made to improve quality of care by means of uniform registration of adverse events and mortality,7 unfortunately, in many countries, comparison of outcomes among health care providers is hampered by the lack of a clear definition of complications.8,9 Moreover, when comparing outcomes of treatment, the severity of complications is usually not taken into account; however, differences in recorded severity may reveal differences in quality of care and subsequently provide opportunities for improving quality of care. In 1992, Clavien and colleagues10 developed a classification system that defined the severity of the complication based on the actions necessary to treat it. The system initially was not widely used, although a modified version substantially gained popularity after it was validated in a large cohort of patients and was shown to have good reproducibility among surgeons.11 Limited information on the consequences and severity of complications is found in the surgical literature. We hypothesized that the impact of comparable complications is highly variable. The aim of our study was to prospectively evaluate the severity and consequences of all complications arising in a general surgical practice and to evaluate whether identically recorded complications had predictable and consistent severity grades. From these results, we can infer whether crude complication rates can serve as indicators of quality of care and outcome measures in scientific research, or whether gradation of complications is obligatory for adequate comparison of outcomes.

Background The objectives of this study were to evaluate the accuracy of a prospective complication registry for documenting complications and identify possible factors for non-registering. Methods Five hundred randomly selected patients admitted at the Department of Surgery of St. Elisabeth Hospital Tilburg, The Netherlands, in the year 2005, were evaluated for incidence and type of complications by an examination of their medical records and compared with a prospective complication registry. The system was independently reviewed by two persons for missing complications. Patient files with missing complications in the registry were screened for factors possibly responsible for non-registering. Results Two hundred thirteen complications were detected, 58 (27%) missing in the registry. There were 50 different types of complications documented. The number of events missing per category were: drug-related (50%, n = 4), organ dysfunction (44%, n = 14), infection-related (25%, n = 19), surgery/intervention-related (23%, n = 14), and hospital-provider errors (19%, n = 7). Not all clinically important complications were adequately documented (e.g., anastomotic leakage). The kappa score was 0.695, making the interrater reliability substantial. Conclusion The accuracy of registering complications is fairly acceptable compared to the ranges mentioned in literature. It is disappointing that clinically important events are missing in the registry. The inaccuracy could be explained by a great diversity of documented events, due to a broad definition, suggesting ignorance of the responsible team of which events to register.

Background Adverse events occur in 3·8–17 per cent of hospital admissions. The purpose of this study was to analyse the incidence of medical errors and assess the feasibility of an error registry for quality improvement programmes. Methods Errors were recorded prospectively in a complication registry between 1 June 2005 and 31 December 2007. Events were coded according to the Trauma Registry of the American College of Surgeons; the nature of events was recorded and the severity graded using the 1992 Clavien system. Recorded events were discussed by the medical staff on a daily basis and, if by consensus judged to be errors, were saved to the registry database. Results Of 12 121 patients admitted to the surgical ward during the study interval, 2033 (16·8 per cent) had a complication and 735 (6·1 per cent) had an error documented in the registry. Of 873 recorded errors, 607 (69·5 per cent) were of little or no consequence (Clavien grade I) and 220 (25·2 per cent) required therapeutic intervention (Clavien grade IIa and IIb). Errors leading to permanent injury (Clavien grade III) occurred in 41 instances (4·7 per cent) and five patients (0·6 per cent) died (Clavien grade IV). Conclusion This study shows that errors are common in surgery, and that near misses are more frequent than errors with serious consequences. It is hypothesized that registration of near misses might prevent errors with serious consequences and thus improve quality of care.

This retrospective cohort study was conducted to investigate whether operative treatment of patients with a pertrochanteric femoral fracture outside working hours is associated with an increased risk of complications and higher mortality. During the study period 165 patients were operated on outside working hours and 123 were operated on during working hours (08.00 to 17.00). There was no difference in the rate of early complications (outside working hours 33% versus working hours 33%, p = 0.91) or total complications during follow-up (outside working hours 40% versus working hours 41%, p = 0.91). Both in-hospital mortality (outside working hours 12% versus working hours 11%, p = 0.97) and mortality after one year (outside working hours 29% versus working hours 27%, p = 0.67) were comparable. Adjustment for possible confounders by multivariate logistic regression analysis revealed no increased risk of complications when patients were operated on outside working hours. On the basis of these data, there is no medical reason to postpone operative reduction and fixation in patients with a proximal femoral fracture until working hours.

BACKGROUND: Preoperative imaging has been demonstrated to improve diagnostic accuracy in appendicitis. This prospective study assessed the accuracy of a diagnostic pathway in acute appendicitis using ultrasonography (US) and complementary contrast-enhanced multidetector CT in a general community teaching hospital. STUDY DESIGN: One hundred fifty-one patients with clinically suspected appendicitis followed the designed protocol: patients underwent operations after a primary performed positive US (graded compression technique) or after complementary CT (contrast-enhanced multidetector CT) when US was negative or inconclusive. Patients with positive CT findings underwent operations. When CT was negative for appendicitis, they were admitted for observation. Results of US and CT were correlated with surgical findings, histopathology, and followup. RESULTS: Positive US was confirmed at operation in 71 of 79 patients and positive CT was confirmed in all 21 patients. All 39 patients with negative CT findings recovered without operations. The negative appendicitis rate was 8% and perforation rate was 9%. The sensitivity and specificity of US was 77% and 86%, respectively. The sensitivity and specificity of CT was both 100%. The sensitivity and specificity of the whole diagnostic pathway was 100% and 86%, respectively. CONCLUSIONS: A diagnostic pathway using primary graded compression US and complementary multidetector CT in a general community teaching hospital yields a high diagnostic accuracy for acute appendicitis without adverse events from delay in treatment. Although US is less accurate than CT, it can be used as a primary imaging modality, avoiding the disadvantages of CT. For those patients with negative US and CT findings, observation is safe.

We agree with Marfella et al. (1) that increased free radical generation could very well be a common denominator of the mechanisms by which elevations in blood glucose influence baroreflex sensitivity (BRS) in healthy subjects, as we have proposed (2). Free radicals influence Na+-K+-ATPase enzyme activity and intracytosolic free Ca2+ content at the cellular level as well as …
