Is Adherence to Follow-Up After Bariatric Surgery Necessary? A Systematic Review and Meta-Analysis.

The association of adherence to follow-up (FU) after laparoscopic gastric bypass - and gastric sleeve with weight loss (WL) is unclear. The aim of this study was to evaluate this association. Fourteen full text articles were included in the systematic review. Eight studies were included in the meta-analysis concerning FU up to 3 years postoperatively and 3 for the FU between 3 and 10 years postoperatively. Results showed a significant association between adherence to FU 0.5 to 3 years postoperatively and percentage excess WL (%EWL) but did not demonstrate a significant association between FU > 3 years postoperatively and total WL (%TWL). In conclusion, adherence to FU may not be associated with WL and therefore stringent lifelong FU in its current form should be evaluated.

Root causes and preventability of emergency department presentations of older patients: a prospective observational study.

OBJECTIVE: More older patients are presenting to the emergency department (ED). It is important to know why these patients present and if the ED is the best place for them to receive the care they need. The primary aim of this study was to identify organisational-related, technical-related, healthcare worker-related and patient-related factors leading to ED presentations of older patients. The secondary aim was to determine patients' and caregivers' perspectives on what kinds of ED presentations are potentially preventable. DESIGN: This is a prospective observational study. A root cause analysis was performed by the Prevention and Recovery Information System for Monitoring and Analysis method. It used basic administrative data collected from patient records and interviews of patients, general practitioners (GPs) and physicians at the ED. SETTING: The ED of an academic hospital in the Netherlands. PARTICIPANTS: 100 older patients (aged ≥70 years) who attended the ED between November 2017 and March 2018. RESULTS: In 100 patients presenting to the ED, 159 factors that contributed to presentation were identified; most of these factors were related to underlying diseases (59%) and patient-related factors (18%). These presentations were considered potentially preventable by 23% of the physicians at the ED and 21% of the GPs, but only 10% of the patients. In only four cases was there overall agreement between the patients and the healthcare workers. CONCLUSION: The most frequent underlying factors contributing to an ED presentation in older patients are disease-related and patient-related. The low percentage of ED presentations considered potentially preventable shows that a 'preventable ED presentation' is difficult to define and therefore interventions to reduce them are unlikely to be simple. Novel solutions within the acute care pathway are required in order to deliver care of optimal quality and safety to older patients.

Total weight loss after laparoscopic Roux-en-Y gastric bypass is influenced by preoperative weight loss: can we predict the outcome?

BACKGROUND: Preoperative weight loss (WL) is associated with higher postoperative WL at 1- to 2-year follow-up in patients who undergo laparoscopic Roux-en-Y gastric bypass (LRYGB). OBJECTIVE: To evaluate the possible association between preoperative and postoperative WL at 3-year follow-up and identify risk factors for insufficient WL. SETTING: A single-center prospective cohort study in the Netherlands. METHODS: Patients undergoing primary LRYGB and laparoscopic conversion from band to bypass (redo LRYGB) were instructed to lose weight preoperatively. Follow-up data were collected 1, 2, and 3 years postoperatively. WL was described as percentage total weight loss (%TWL) and percentage excess body mass index (BMI) loss. Patients were divided into 2 groups: group A lost any amount of weight; group B did not lose any weight or gained weight preoperatively. RESULTS: Group A consisted of 230 patients (median preoperative %TWL, 4.8%), and group B consisted of 46 patients (median preoperative %TWL, -1.3%). Median BMI at intake was 44.1 kg/m2. Baseline characteristics were similar. The %TWL and BMI for group A and B in the patients who underwent primary LRYGB at 1, 2, and 3 years was 32.2% (BMI, 28.6 kg/m2) versus 23.9% (BMI, 32.2 kg/m2), 31.8% (BMI, 28.9 kg/m2) versus 25.2% (BMI, 31.9 kg/m2), and 33.3% (BMI, 29.7 kg/m2) versus 21.9% (BMI, 34 kg/m2), respectively, all P < .05. In patients who underwent redo LRYGB no clinically significant differences in postoperative BMI were found. CONCLUSIONS: Preoperative WL in primary patients who undergo LRYGB can be useful to identify those at risk of inadequate postoperative WL. In patients who undergo redo LRYGB different risk factors should be considered for prediction of inadequate postoperative WL.
