PROphylactic closed incision Negative-PRESSure treatment in open incisional hernia repair: Protocol for a multicenter randomized trial (PROPRESS study)

Background

Negative Pressure Therapy in closed incisions (ciNPT) after surgery has shown positive effects including reduction of Surgical Site Infection (SSI) incidence. In patients undergoing elective open incisional hernia repair, however, ciNPT is not standard care, perhaps due to high-quality evidence still not provided. This study hypothesizes that this patient group would benefit from ciNPT by reducing wound complications and improving postoperative quality of life.

Method

This is a multicenter Randomized Controlled Trial (RCT) including a total of 110 patients allocated in a 1:1 ratio with one intervention arm and one active control arm receiving ciNPT (i.e., Prevena™) and standard wound dressing, respectively. The primary outcome is the incidence of SSI at 30 days postoperatively and secondary outcomes are 1) pooled incidence of Surgical Site Occurrence (SSO), 2) patient-reported pain and satisfaction with the scar, and 3) hernia-related quality of life.

Conclusion

Patients undergoing elective open incisional hernia repair are fragile with a high risk of wound complication development. This multicenter RCT seeks to deliver the high-quality evidence needed to establish the role ciNPT must play for exactly this group with the aim of reducing SSI incidence and health economic costs, and finally improving quality of life. There are no theoretical or clinical experience of unwanted consequences of this treatment.

Enhanced recovery after robotic ventral hernia repair: factors associated with overnight stay in hospital

PURPOSE

Enhanced recovery after surgery (ERAS) protocols lead to reduced post-operative stay and improved outcomes after most types of abdominal surgery. Little is known about the optimal post-operative protocol after robotic ventral hernia repair (RVHR), including the potential limits of outpatient surgery. We report the results of an ERAS protocol after RVHR aiming to identify factors associated with overnight stay in hospital, as well as patient-reported pain levels in the immediate post-operative period.

METHODS

This was a prospective cohort study of consecutive patients undergoing RVHR. Patients were included in a prospective database, registering patient characteristics, operative details, pain and fatigue during the first 3 post-operative days and pre- and 30-day post-operative hernia-related quality of life, using the EuraHS questionnaire.

RESULTS

A total of 109 patients were included, of which 66 (61%) underwent incisional hernia repair. The most performed procedure was TARUP (robotic transabdominal retromuscular umbilical prosthetic hernia repair) (60.6%) followed by bilateral roboTAR (robotic transversus abdominis release) (19.3%). The mean horizontal fascial defect was 4.8 cm, and the mean duration of surgery was 141 min. In total, 78 (71.6%) patients were discharged on the day of surgery, and factors associated with overnight stay were increasing fascial defect area, longer duration of surgery, and transverse abdominis release. There was no association between post-operative pain and overnight hospital stay. The mean EuraHS score decreased significantly from 38.4 to 6.4 (P < 0.001).

CONCLUSION

An ERAS protocol after RVHR was associated with a high rate of outpatient procedures with low patient-reported pain levels.

Long-term predictors of loss of asthma control in school-aged well-controlled children with mild to moderate asthma: A 5-year follow-up

BACKGROUND

Long-term follow-up studies establishing risk factors for loss of asthma control in well-controlled children with mild to moderate disease are lacking and are of importance for improving patient quality of life and utilization of health-care resources.

METHODS

Loss of asthma control was assessed in 146 school-aged children with well-controlled mild to moderate asthma from a Danish pediatric asthma outpatient clinic based on hospital admissions, emergency department (ED), or outpatient management of exacerbations, oral corticosteroid (OCS) use, or step-up of regular asthma treatment according to Global Initiative for Asthma (GINA) guidelines through a 5-year follow-up period. Risk factors included sex, ethnicity, age, body mass index (BMI), atopic comorbidity and predisposition, lung function, fractional exhaled nitric oxide (FeNO) level, exercise challenge test results, regular physical activity, GINA treatment step at baseline, and adherence to controller therapy.

RESULTS

A total of 27 (18%) children experienced 56 acute events defined by hospital admission, ED, or outpatient management. Risk of experiencing any acute event was increased with female sex (adjusted odds ratio, aOR = 2.4 (1.0-5.9), p = 0.047) and higher baseline GINA treatment step (aOR = 1.6 (1.1-2.5), p = 0.03). Furthermore, female sex (aOR = 6.1 (1.4-42.2), p = 0.01) and higher FeNO (aOR = 1.8 (1.0-3.2), p = 0.04) were associated with OCS prescriptions, whereas no risk factors were identified for GINA treatment step-up during the 5-year follow-up.

CONCLUSIONS

Female sex, higher FeNO, and higher baseline GINA treatment step increase the risk of long-term loss of control including acute events and OCS use in well-controlled children with mild to moderate asthma. These findings are important for primary physicians and clinicians in asthma outpatient clinics to identify seemingly well-controlled children at risk to plan more frequent follow-ups.

Allergic Comorbidity Is a Risk Factor for Not Attending Scheduled Outpatient Visits in Children with Asthma

Asthma is one of the most common chronic diseases in children globally. Previous studies have shown that not attending asthma primary care consultations is associated with poorer treatment adherence and increased risk of loss of asthma control on a short-term basis. Here, we investigated long-term patterns and predictors of not attending scheduled asthma outpatient visits during 5-years of follow-up in 146 children with asthma. Of the 146 children, 67 (46%) did not attend at least one scheduled appointment, amounting to a total of 122 (10.8%) missed of 1133 scheduled appointments. In a multivariate analysis adjusting for total scheduled visits in the 5-year period any allergic sensitization was a significant risk factor for not attending ≥1 scheduled appointment (aOR = 6.6 (95% CI, 1.3–39.7), p = 0.03), which was not the case for asthma treatment step or lung function. Furthermore, atopic predisposition decreased the risk of non-attendance (aOR = 0.36 (0.13–0.92), p = 0.04). We found no association between non-attendance, treatment adherence or loss of asthma control. This study highlights that allergic comorbidity, but not degree of asthma severity, identifies a group of children with asthma who are prone to not attend scheduled outpatient appointments.

Assessment of adherence to asthma controllers in children and adolescents

BACKGROUND

Low adherence to asthma controllers is known to increase the risk of uncontrolled disease and poor health outcomes. We aimed to study risk factors of long-term adherence to preventive medications in children and adolescents with asthma.

METHODS

Adherence was assessed during a two-year period in 155 children with asthma followed in a tertiary pediatric asthma outpatient clinic using percentage of days covered (PDC) based on physician prescriptions and pharmacy claims data. The risk factor analysis included age, sex, ethnicity, BMI, atopic comorbidity, spirometry incentives, and fractional exhaled nitric oxide (FeNO).

RESULTS

Ninety-five children, 50 (53%) males, mean age of 16.3 years (SD, 2.36), received at least one prescription for asthma controllers in the study period. Fifty-two (54%) children were classified as non-adherent with a PDC cutoff at 80%. Adherence was negatively associated with age: adherence ratio (AR) 0.84 (95% CI, 0.73-0.95), P = .008; forced expiratory volume in 1 second (FEV1): AR per L 0.6 (0.91-1.0), P = .03; unfilled inhaled beta-2-agonist prescription: AR 0.45 (0.23-0.89), P = .02; and FeNO level: AR per ppb 0.98 (0.97-0.99), P = .03, where age and FeNO retained significance in multivariate analysis. Type and number of asthma controllers were not associated with adherence.

CONCLUSIONS

This study shows low adherence to preventive medication among half of the children with asthma, which is associated with increasing age and FeNO level. Therefore, an extra effort should be directed toward teenagers transitioning from pediatric to adult medicine and toward inhaled corticosteroid-treated patients with elevated FeNO to increase their adherence to asthma controllers.
