About

This study aims to study the efficacy of a preoperative "bundle" of interventions, which consists of preoperative physiotherapy, nutritional support and cognitive exercises on elderly frail patients undergoing major abdominal surgery, and evaluating their outcomes. There will be two arms, intervention and control.

Full description

Frailty is a geriatric syndrome, defined as an increased vulnerability to stressors leading to a state of decreased physiological resistance. It is characterised by a "constellation of symptoms and signs that describe the heterogeneous response of older adults to physiological and metabolic challenges." While frailty is not necessarily synonymous with chronological age, it is more prevalent among the older adult population and is associated with up to a threefold increased risk of mortality or major morbidity postsurgery. Thus, it has become critically important for healthcare systems to develop strategies designed to improve clinical outcomes in this high-risk population when undergoing surgeries.

Currently there is no clear intervention that has been proven to modify the syndrome of frailty or its impact on postoperative outcomes. This study investigates a novel multidisciplinary approach that can be implemented within a short time frame prior to surgery.

We plan to study the efficacy of a preoperative "bundle" of interventions, which consists of preoperative physiotherapy, nutritional support and cognitive exercises on elderly frail patients undergoing major abdominal surgery, and evaluating their outcomes based 1) length of hospital stay 2) Functional recovery from surgery 3) post-operative complications.

Enrollment: 62 estimated patients

Sex: All

Ages: 65+ years old

Volunteers: Accepts Healthy Volunteers

Inclusion criteria

1. Patients attending the Preoperative Evaluation Clinic, SGH at least 11 days prior to his/her elective major abdominal surgery. Major abdominal surgery is defined as an intraperitoneal surgery with expected length of stay beyond 2 days. For patients who attended the clinic more than 11 days prior to surgery date, they will be informed to start their prehabilitation bundle 10 days prior to surgery.
2. Aged 65 and above
3. Diagnosed as frail based on Fried criteria score 3and above
4. Able to understand and follow the prescribed cognitive and physical exercise

Exclusion criteria

1. Patients with Parkinson disease, previous stroke, neuromuscular disorders and those taking carbidopa/levodopa, donepezil hydrochloride or antidepressants as previous studies have found that these medications may cause symptoms that are similar with domains of frailty.
2. Patients who are not able to communicate

Trial design

Primary purpose: Treatment

Allocation: Randomized

Interventional model: Parallel Assignment

Masking: Single Blind

62 participants in 2 patient groups

Intervention

Active Comparator group

Description:

In the interventional arm, patients will be given: 1. A 'Threshold' Inspiratory Muscle Trainer 2. A nutritional assessment: if needed, dietary supplements prescribed (i.e Ensure, Glucerna). 3. Cognitive exercise in the form of the 'Memory' card game will be taught to the patients and the caregiver (if available), to be done twice a day. Patients will be provided with a protocol activities log and a study assistant will be conducting a telephone conversation on day 1, 4 and 7 to encourage compliance to the protocol and answer any queries with regards to the research study.

Treatment:

Device: 'Threshold' Inspiratory Muscle Trainer, Respironics of New Jersey Inc

Dietary Supplement: Ensure, Resource 2.0 and Glucerna

Other: Cognitive Training, Memory Card Game

Control

No Intervention group

Description:

In the control arm, patients will be given the standard education materials regarding surgery and carry out daily activities as usual until the admission of the surgery.
