Efficiency of a virtual fracture care protocol in non-operative treatment of adult patients with a distal radial fracture

This study aimed to determine the effects of virtual fracture care (VFC) on secondary healthcare utilization in non-operative treatment of adult patients with a distal radial fracture. A retrospective cohort study was performed, including those who received non-operative treatment without VFC (pre-VFC) and with VFC (VFC). Outcomes included secondary healthcare utilization, calculated treatment costs, emergency department (ED) reattendances and complication rates. In total, 88 pre-VFC and 99 VFC patients were included. Pre-VFC patients had more follow-up appointments, with a median of 4 (IQR: 3) versus a median of 4 (IQR: 1) in VFC patients. In addition, 3% of follow-up appointments for pre-VFC patients were performed remotely compared to 18% for VFC patients. Complications and ED reattendances were comparable between groups. In this study, non-operative treatment of adult patients with a distal radial fracture through VFC reduced secondary healthcare utilization, with similar reported complication and ED reattendance rates compared with treatment without VFC.Level of evidence: III.

Patient perceptions after the operative and nonoperative treatment of shoulder instability: A qualitative focus group study

Background

Little evidence is available regarding patient perceptions of the treatment of shoulder instability. The aim of this study is to investigate patient perceptions regarding the operative and nonoperative treatment of anterior shoulder instability.

Methods

Patients who presented to the emergency department or outpatient clinic between 2016 and 2020 were retrospectively selected using diagnosis and procedure codes. Online focus groups and semistructured interviews were conducted, systematically recorded and subsequently transcribed to MaxQDA 2007 for qualitative analysis. Coded transcripts of all focus groups were subjected to a grounded theory-based analysis.

Results

Six focus groups and two semistructured interviews were hosted with 35 included patients. The mean age of included patients was 34.1 years (±11.5). Eight patients were female (23%), and 27 patients were male (77%). Fear of (recurrent) dislocation, preoperative counseling, communication between surgeon and physiotherapists and need for a consistent postoperative rehab protocol turned out to be important patient perceptions. The most crucial factor for discontent was a lack of communication from the surgeon.

Discussion

This patient-centered focus group study revealed that fear of (recurrent) dislocation, preoperative counseling, communication between surgeons and physiotherapists and the need for a consistent postoperative rehabilitation protocol was the most frequently discussed themes.

Effect of Antibiotic Prophylaxis on Surgical Site Infections Following Removal of Orthopedic Implants Used for Treatment of Foot, Ankle, and Lower Leg Fractures: A Randomized Clinical Trial

IMPORTANCE

Following clean (class I, not contaminated) surgical procedures, the rate of surgical site infection (SSI) should be less than approximately 2%. However, an infection rate of 12.2% has been reported following removal of orthopedic implants used for treatment of fractures below the knee.

OBJECTIVE

To evaluate the effect of a single dose of preoperative antibiotic prophylaxis on the incidence of SSIs following removal of orthopedic implants used for treatment of fractures below the knee.

DESIGN, SETTING, AND PARTICIPANTS

Multicenter, double-blind, randomized clinical trial including 500 patients aged 18 to 75 years with previous surgical treatment for fractures below the knee who were undergoing removal of orthopedic implants from 19 hospitals (17 teaching and 2 academic) in the Netherlands (November 2014-September 2016), with a follow-up of 6 months (final follow-up, March 28, 2017). Exclusion criteria were an active infection or fistula, antibiotic treatment, reimplantation of osteosynthesis material in the same session, allergy for cephalosporins, known kidney disease, immunosuppressant use, or pregnancy.

INTERVENTIONS

A single preoperative intravenous dose of 1000 mg of cefazolin (cefazolin group, n = 228) or sodium chloride (0.9%; saline group, n = 242).

MAIN OUTCOMES AND MEASURES

Primary outcome was SSI within 30 days as measured by the criteria from the US Centers for Disease Control and Prevention. Secondary outcome measures were functional outcome, health-related quality of life, and patient satisfaction.

RESULTS

Among 477 randomized patients (mean age, 44 years [SD, 15]; women, 274 [57%]; median time from orthopedic implant placement, 11 months [interquartile range, 7-16]), 470 patients completed the study. Sixty-six patients developed an SSI (14.0%): 30 patients (13.2%) in the cefazolin group vs 36 in the saline group (14.9%) (absolute risk difference, -1.7 [95% CI, -8.0 to 4.6], P = .60).

CONCLUSIONS AND RELEVANCE

Among patients undergoing surgery for removal of orthopedic implants used for treatment of fractures below the knee, a single preoperative dose of intravenous cefazolin compared with saline did not reduce the risk of surgical site infection within 30 days following implant removal.

Trauma surgery by general surgeons: Still an option for proximal femoral fractures?

INTRODUCTION

Surgery for proximal femoral fractures in the Netherlands is performed by trauma surgeons, general surgeons and orthopaedic surgeons. The aim of this study was to assess whether there is a difference in outcome for patients with proximal femoral fractures operated by trauma surgeons versus general surgeons. Secondly, the relation between hospital and surgeon volume and postoperative complications was explored.

METHODS

Patients of 18 years and older were included if operated for a proximal femoral fracture by a trauma surgeon or a general surgeon in two academic, eight teaching and two non-teaching hospitals in the Netherlands from January 2010 until December 2013. The combined endpoint was defined as reoperation or surgical site infection. Multivariate analysis was used to adjust for patient and fracture characteristics and hospital and surgeon volume. Categories for hospital volume were>170/year (high volume), 96-170/year (medium volume) and <96/year (low volume).

RESULTS

In 4552 included patients 2382 (52.3%) had surgery by a trauma surgeon. Postoperative complications occurred in 276 (11.6%) patients operated by a trauma surgeon and in 258 (11.9%) operated by a general surgeon (p=0.751). When considering confounders in a multivariate analysis, surgery by trauma surgeons was associated with less postoperative complications (OR 0.746; 95%CI 0.580-0.958; p=0.022). Surgery in high volume hospitals was also associated with less complications (OR 0.997; 95%CI 0.995-0.999; p=0.012). Surgeon volume was not associated with complications (OR 1.008; 95%CI 0.997-1.018; p=0.175).

CONCLUSION

Surgery by trauma surgeons and high hospital volume are associated with less reoperations and surgical site infections for patients with proximal femoral fractures.

Wound Infections Following Implant removal below the knee: the effect of antibiotic prophylaxis; the WIFI-trial, a multi-centre randomized controlled trial

Background

In the Netherlands about 18,000 procedures with implant removal are performed annually following open or closed reduction and fixation of fractures, of which 30-80% concern the foot, ankle and lower leg region. For clean surgical procedures, the rate of postoperative wound infections (POWI) should be less than ~2%. However, rates of 10-12% following implant removal have been reported, specifically after foot, ankle and lower leg fractures. Currently, surgeons individually decide if antibiotics prophylaxis is given, since no guideline exists. This leads to undesirable practice variation. The aim of the study is to assess the (cost-)effectiveness of a single intravenous gift of Cefazolin prior to implant removal following surgical fixation of foot, ankle and/or lower leg fractures.

Methods

This is a double-blind randomized controlled trial in patients scheduled for implant removal following a foot, ankle or lower leg fracture. Primary outcome is a POWI within 30 days after implant removal. Secondary outcomes are quality of life, functional outcome and costs at 30 days and 6 months after implant removal. With 2 x 250 patients a decrease in POWI rate from 10% to 3.3% (expected rate in clean-contaminated elective orthopaedic trauma procedures) can be detected (Power = 80%, 2-sided alpha = 5%, including 15% lost to follow up).

Discussion

If administration of prophylactic antibiotics prior to implant removal reduces the infectious complication rate, this will offer a strong argument to adopt this as standard practice of care. This will consequently lead to less physical and social disabilities and health care use. A preliminary, conservative estimation suggests yearly cost savings in the Netherlands of € 3.5 million per year.

Hypercalcemia in patients with bipolar disorder treated with lithium: a cross-sectional study

BACKGROUND

Lithium-induced hyperparathyroidism (LIH) is a relative underrecognized complication of long-term lithium treatment. Hypercalcemia may be the first, but often overlooked, sign of LIH. Symptoms of LIH can be similar to the underlying psychiatric illness, which may cause a significant doctor's delay in diagnosing LIH. The aim of this study was to determine the prevalence of hypercalcemia in a cohort of psychiatric patients.

METHODS

In this cross-sectional study, we collected data from 314 patients treated with lithium in an outpatient clinic for bipolar disorder. Patients with bipolar disorder from the same clinics, who had never been treated with lithium and of whom serum calcium levels were available, were included as controls (n = 15). Patient characteristics and laboratory results were collected during the period of June 2010 till June 2011.

RESULTS

The mean serum calcium level was 2.49 (SD 0.11) mmol/l. The point prevalence of hypercalcemia (>2.60 mmol/l) was 15.6%. In a comparable group of psychiatric patients not using lithium, the mean serum calcium level was 2.37 mmol/l, and none of these patients had hypercalcemia (p = 0.001). The duration of lithium treatment was the only significant predictor for the development of hypercalcemia (p = 0.002).

DISCUSSION

The prevalence of hypercalcemia in lithium-treated patients was significantly higher than that in non-lithium treated controls and correlated to the cumulative time lithium was used in this cross-sectional study. We recommend that serum calcium levels should be routinely tested in patients using lithium for timely detection of LIH or hypercalcemia due to other causes.

Differences between sporadic and MEN related primary hyperparathyroidism; clinical expression, preoperative workup, operative strategy and follow-up

Background

Primary hyperparathyroidism (PHPT) is most commonly sporadic (sPHPT). However, sometimes PHPT develops as part of multiple endocrine neoplasia (MEN) type 1 or 2A. In all, parathyroidectomy is the only curative treatment. Nevertheless, there are important differences in clinical expression and treatment.

Methods

We analyzed a consecutive cohort of patients treated for sporadic, MEN1-related, and MEN2A-related PHPT and compared them regarding clinical and biochemical parameters, differences in preoperative workup, operative strategies, findings, and outcome.

Results

A total of 467 patients with sPHPT, 52 with MEN1- and 16 with MEN2A-related PHPT were analyzed. Patients with sPHPT were older, more often female and had higher preoperative calcium and parathyroid hormone levels, when compared with MEN1 and MEN2A patients. Minimally invasive parathyroidectomy (MIP) was performed in 367 of 467 sPHPT patients (79%). One abnormal parathyroid was found in 426 patients (91%). Two or more in 35 patients (7%). In six patients (1%) no abnormal parathyroid gland was retrieved. Of 52 MEN1 patients, eight (15%) underwent a MIP and 44 patients (85%) underwent conventional neck exploration (CNE); with resection of fewer than 3½ enlarged glands in 21 patients (40%), subtotal parathyroidectomy (SPTX, 3-3½ glands) in seventeen (33%) and total parathyroidectomy with autotransplantation (TPTX) in six (12%). Eleven patients (21%) had persistent disease, 29 (56%) recurrent PHPT and nine (17%) permanent hypoparathyroidism, mostly after TPTX. Of 16 MEN2A patients, six (38%) underwent MIP, four (25%) CNE and six (38%) selective resection of the enlarged gland(s) during total thyroidectomy. Three patients (19%) suffered from persistent PHPT and two (13%) developed recurrent disease.

Conclusions

Sporadic PHPT, MEN1- and MEN2A-related PHPT are three distinct entities as is reflected preoperatively by differences in gender, age at diagnosis and calcium and PTH levels.

MEN2A patients are very similar to sPHPT with respect to operative approach and findings. MIP is the treatment of choice for both. MIP has low rates of persistent and recurrent PHPT and a low complication rate. The percentage of multiglandular disease and recurrences are significantly higher in MEN1 patients, demonstrating the need for a different approach. We advocate treating these patients with CNE and SPTX.

Randomized clinical trial of LigaSure versus conventional suture ligation in thyroid surgery

BACKGROUND

In thyroid surgery vessel division and haemostasis make up an important and time consuming part of the operation. While the presence of the recurrent laryngeal nerve limits the liberal use of diathermia, the many arterial and venous branches to and from the thyroid gland necessitates the use of numerous conventional suture ligatures.This study evaluates the effect of using a vessel sealing system on operation time during thyroid surgery.

METHODS

A randomized clinical trial was performed between September 2005 and October 2008 in a teaching hospital. Forty patients undergoing total hemithyroidectomy participated in the trial. Twenty were randomized to the intraoperative use of the LigaSure Precise™ vessel sealing system, and twenty to the use of conventional suture ligatures.

RESULTS

The total median operation time was 10 minutes shorter in the LigaSure group (56 versus 66 minutes, P = 0.001). No significant differences in complications were noticed.

CONCLUSION

Using an electrothermal vessel sealing system during thyroid surgery is time saving.

TRIAL REGISTRATION

This trial was registered in the international standard randomized controlled trials number register (ISRCTNR) under number ISRCTNR82389535.

[Lithium-induced hyperparathyroidism]

Lithium is a medication successfully being used for the treatment of bipolar disorder. Lithium-induced hyperparathyroidism (LIH) is a little known complication that may arise due to the use of lithium. Symptoms of LIH are often similar to the underlying psychiatric illness for which lithium was indicated. It is thus difficult to differentiate between these, resulting in significant 'doctors' delay' in the diagnosis of LIH. The authors present three cases in this article. In the first case concerning a 51-year-old woman, they illustrate that LIH and subsequent hypercalcaemia are often diagnosed by coincidence. In the second case concerning a 47-year-old woman, they show that it can be quite complicated to locate the underlying aberration of the parathyroid and that medication may be an eligible alternative to surgery. In the third case, a 56-year-old woman, they show the need for cogency regarding appropriate surgical strategy as recurrences are quite common.

The additional value of intraoperative parathyroid hormone assessment is marginal in patients with nonfamilial primary hyperparathyroidism: a prospective cohort study

BACKGROUND

The success of minimally invasive parathyroidectomy is attributed to evolving preoperative imaging techniques and intraoperative parathyroid hormone (IOPTH) measurement. The additional value of IOPTH measurement in patients undergoing surgery for primary hyperparathyroidism (pHPT) was evaluated.

METHODS

Between 1999 and 2010 there were 119 patients who underwent surgery for pHPT at our institutions. In all patients, preoperative imaging was performed and IOPTH samples were collected prospectively but the results were not disclosed during surgery.

RESULTS

Postoperative calcium level normalized in 114 patients (96%). The 5 surgical failures represented the maximum yield of IOPTH sampling. Three of these patients would have been identified intraoperatively by an inadequate IOPTH decrease, whereas IOPTH decreased inaccurately in the other 2 patients. In addition, in 1 of these 3 patients no abnormal gland was found during minimally invasive parathyroidectomy and subsequent conventional neck exploration. Therefore, only 2 reoperations would have been prevented (1.7%).

CONCLUSIONS

IOPTH would have changed the outcome in 2 patients, increasing the biochemical cure rate from 96% to 98%. We believe that although it can be helpful in certain cases, it may not be necessary routinely in patients treated for pHPT.

Shifting incidence of solitary adenomas in the era of minimally invasive parathyroidectomy. A multi-institutional study

BACKGROUND

Previously, when a conventional neck exploration (CNE) without preceding diagnostic imaging was the surgical treatment for patients with primary hyperparathyroidism (pHPT) solitary adenomas were observed in 69-88% of patients. The advent of minimally invasive parathyroidectomy (MIP), aiming at a preoperatively identified parathyroid abnormality may be associated with a different incidence of solitary and multiglandular parathyroid disease.

MATERIALS AND METHODS

In a cohort of 467 patients with sporadic pHPT who preferentially underwent MIP in four hospitals in the same geographical region, the incidence of solitary adenomas, multiple adenomas, and multiglandular hyperplasia (MGD) was evaluated.

RESULTS

A total of 367 patients were scheduled for MIP; 100 patients underwent a planned CNE. The overall surgical success rate of the first operation was 93%, and the cumulative success rate, including a second operative procedure, was 99%. Normocalcemia resulted from removing 1 abnormal PG in 426 patients (91%) and more than one abnormal gland in 35 patients (8%). A parathyroid carcinoma was diagnosed in four of the 426 patients with a single abnormal gland. Four gland hyperplasia was observed in 1 patient. In hospitals where diagnostic workup usually consisted of ultrasound (US) and computed tomography (CT) the incidence of solitary adenomas was 88%, compared with 96% in hospitals where MIBI, US, and CT were used preoperatively (P = 0.007).

CONCLUSIONS

A higher frequency of solitary adenomas was observed than historically reported. The extent of the preoperative workup influences the number of observed solitary adenomas.

Colo-colonic intussusception caused by a submucosal lipoma: case report and review of the literature

Adult intussusception is a rare clinical presentation and often not considered clinically in the differential diagnosis of adult patients with vague abdominal complaints. A 44-year-old woman visited our emergency department with sudden onset of intermittent abdominal pain. Diagnostic imaging revealed an intussusception caused by a submucosal lipoma of the sigmoid. A laparotomy was performed and the diagnosis was proven by histological examination. Submucosal lipomas are usually asymptomatic but may cause bleeding, obstruction, intussusception, or abdominal pain and thus mimic a malignancy. Surgical excision is indicated for symptomatic cases.
