Obesity Clinical Trial

Official title: Cost-effectiveness Pharmacoeconomic Study of a Standardized Multidisciplinary Weight Loss Method (PronoKal® Method) to Improve the Health Condition of Obese Patients With Associated Comorbidities

Status Withdrawn

Clinical Trial Summary

Prospective, observational, multicenter study based on a registry of patients with obesity and associated comorbidities undergoing a standardized multidisciplinary weight loss method with a 2-year follow-up.

Clinical Trial Description

The investigators will include obese patients with BMI higher than 30 kg / m2 and one or more comorbidities associated with obesity who are following a standardized multidisciplinary weight-loss program (PronoKal® Method), which consists of a very-low-calorie diet, into which natural foods are gradually reintroduced, accompanied by physical exercise and emotional support.

The aim of this study is to assess the cost-effectiveness to improve the health condition of obese patients with comorbidities and thereby reduce healthcare expenditure (pharmacological treatment, incidence of complications, use of health resources) and work absenteeism.

Patients will be monitored for 2 years. The registry of patient data for this study will be made by the doctor and dietitians / nutritionists who will regularly see the patient in the face-to-face visits at the Pronokal center.

The study will begin with the baseline visit (day 0) in which the inclusion and exclusion criteria will be confirmed, the signing of informed consent will be obtained and the multidisciplinary treatment will be prescribed, followed by 6 control visits: 2 visits during the ketogenic stage (1-month after the start and at the end of ketosis), 2 visits during the physiological adaptation phase (at 4 or 5 months and at the end of stage 2) and 2 follow-up visits during the maintenance up to the 2-year completion.

Likewise, dietitians/nutritionists, according to the methodology of the program, will carry out a face-to-face follow-up of the patient, which will be fortnightly during the ketogenic diet, monthly during the physiological adaptation of stage 2 and quarterly or semi-annual during the maintenance stage.

The information about the endpoints will be collected:

• Costs of weight loss treatment: products and dietary supplements + number of control visits + number of laboratory tests performed

• Healthcare expenditure: pharmacological treatment of associated comorbidities, incidence of complications (visits to his/her primary care physician, a specialist or emergency department for acute complications, treatment of acute complications, number of hospital admission days, antibiotic treatment), consumption of health resources (visits to the general practitioner, visits to specialists, laboratory tests)

• Work absenteeism: number of work leave days + hours of work absenteeism due to health problems or medical visits. ;
