Outcomes from an orientation model to reduce attrition in paediatric weight management.

ABSTRACT: We aimed to reduce attrition of newly referred patients in a paediatric weight management programme by implementing an orientation to address families' expectations and screen for and support behavioural and mental health problems and psychosocial stressors at programme outset. Orientation impact was monitored with run charts with percentages of scheduled encounters completed. Long-term impact was assessed by comparing patients in the initial 6 months of the orientation to a baseline group of referred patients during the same 6-month time interval in the prior year (Pre-Orientation Group). The outcome measure was programme attrition within 15 months. Groups were compared using Kaplan-Meier survival analysis and Cox proportional hazards regression modelling. Patients in the Orientation Group had a 23% increased odds of attrition compared to patients in the Pre-Orientation group (adjusted Hazard ratio, aHR 1.23; 95% confidence interval, CI: 1.01, 1.51) and shorter median duration of follow-up (2.0 vs. 2.9 months, P = 0.004). An increase in body mass index z-score of 1 unit resulted in a nearly fivefold increased odds of attrition (aHR 5.24; 95% CI: 2.95, 9.3). An orientation for new patients did not reduce attrition within 15 months. We suggest that ongoing retention strategies should be embedded into the treatment phase of the programme.

Project description:Objectives: To investigate the impact of the Cambridge Intensive Weight Management Programme (IWMP) on weight change, eligibility for bariatric surgery, HbA1c, and blood pressure. Design: Prospective non-randomized intervention. Setting: The IWMP is a multi-disciplinary weight loss intervention for severely obese patients to avoid or optimize their physiological state thus enabling bariatric surgery. It uses dietary interventions, pharmacotherapy, and physical activity along with behavior change counseling. Participants: Severely obese patients (Body Mass Index, BMI≥40 kg/m2). Interventions: IWMP is a prospective intervention conducted in a National Health Service Tier 3 obesity service. It includes 3 phases of 8 weeks each: weight loss, weight stabilization, and weight maintenance. In each phase, patients adhered to a prescribed dietary regime and attended regular clinic visits. Data included in this analysis are from those who enrolled in IWMP between 2009 and 2013. Primary and secondary measures: The primary outcome was weight change between baseline and completion of the programme. Secondary outcomes included changes in blood pressure, HbA1c and eligibility for bariatric surgery pre-assessment. Changes in outcomes were compared by age, sex, smoking status, and employment. Results: Of n = 222 eligible patients, complete data were available for n = 141 patients (63.5%). At baseline, the mean (SD) BMI was 49.7 (9.2) kg/m2 for women, and 47.9 (7.2) kg/m2 for men. Mean (SD) weight change for women was -18.64 (8.36) kg and -22.46 (10.98) kg for men. N = 97 (69%) of patients achieved ≥10% weight loss. Individuals aged ≤ 50 years lost significantly more weight than those aged >50 years [mean (SD) weight loss: 22.18 (10.9) kg vs. 18.32 (7.92) kg, p = 0.020]. Changes in weight were non-significant by smoking status or employment. Median (IQR) change in systolic and diastolic blood pressure was -6 (-14.6) mmHg and 0 (-8.6) mmHg (non-significant), respectively. There was ~50% reduction in the need for bariatric surgery. Conclusions: For the majority of the patients, IWMP is promoting weight loss and allowing for avoidance of, or optimization before, bariatric surgery.
