Plain English Summary
Background and study aims
The gallbladder is a small, pouch-like organ found underneath the liver, which is responsible for storing bile (a chemical produced by the liver which helps with the digestion of fats) and making it more concentrated. In some cases, if there is too much cholesterol in the bile inside gallbladder, it can lead to the development of small stones (gallstones). In some cases gallstones can be very painful and it may be necessary for the gallbladder to be surgically removed. Older patients experience more complications after gallbladder removal compared with younger patients. However, most studies have not considered patient frailty, particularly in patients who undergo emergency gallbladder removal. The aim of this study is to find out whether there is a link between frailty and poor surgical outcomes (complications and death).
Who can participate?
Patients aged 65 and over who have gallstones who are scheduled for a routine or emergency gallbladder removal.
What does the study involve?
All patients are assessed using the Geriatric Assessment (GA) on the day that they are admitted to hospital. This includes a range of questionnaires and tests designed to evaluate the patient’s physical and emotional functionality as well as their nutritional status and the medications they take, so that their frailty can be determined. Participants then undergo their surgery as per standard practice and are followed up for thirty days so that any complications or death after surgery can be recorded, as well as the length of their hospital stay. This information is then compared with the results of the GA in order to look at the link between frailty and surgical outcomes.
What are the possible benefits and risks of participating?
There are no direct benefits or risks involved with participating in this study.

Geriatric assessment as a qualification element for elective and emergency cholecystectomy in older patients
Acronym
Study hypothesis
1. Frail patients who have qualified for an elective cholecystectomy can be safely operated upon
2. Frail patients who have qualified for an emergency cholecystectomy have higher postoperative morbidity and mortality

Cholecystitis
Intervention
All included patients will be assessed using the Geriatric Assessment, which will be performed on the day of admission by trained physicians or, for emergency patients, by trained physicians or nurses. The GA comprises the validated instruments evaluating functional (Activities of Daily Living - ADL, Instrumental Activities of Daily Living - I-ADL), cognitive (Blessed Orientation-Memory-Concentration Test - BOMC and Clock Drawing Test - CDT), depressive (Geriatric Depression Scale - GDS), nutritional (Mini Nutritional Assessment - MNA) and polypharmacy status (number of drugs taken by the patient) with the range and the literature-based cut-off scores. A cumulative deficit model of frailty will be used. The equally weighted deficits, as a measure of accumulated vulnerability, included ADL/IADL, Geriatric Depression Score, BOMC/CDT, the Mini-Nutritional Assessment, CCS, and the Polypharmacy Assessment. The functional (ADL/IADL) and cognitive domains (BOMC/CDT) will be considered abnormal if one of the assessment tools showed literature-based impairment. The detection of deficits in two or more GA domains indicates an increased risk of disability or death and is used as the cut-off score for the GA set and also as the definition of frailty.
Participation in the study does not change anything in the treatment plan, surgery and postoperative rehabilitation. Enrolled patients will undergo elective/emergency laparoscopic or open cholecystectomy (decision of the surgeon and anesthesiologist). All operations will be performed by residents under the direct supervision of a consultant (who also served as the first assistant) or by the consultants themselves. Laparoscopic cholecystectomy will be performed using a standard three- or four-port technique and all emergency patients were treated surgically within 24 h after admission. Severity grading for the acute cholecystitis patients is according to the 2013 Tokyo Guidelines. The postoperative follow-up regarding postoperative morbidity and mortality will last for 30-days.

Primary outcome measures
1. Post-operative complications, defined as any event occurring within 30 days of surgery that required treatment not routinely applied in the post-operative period, is measured through telephone interviews and clinic visits at 30 days post-surgery
2. Post-operative mortality, defined as death within 30 days after surgery, is measured using review of medical records or contact with the appropriate registry office
Secondary outcome measures
Length of hospital stay, defined as the time between the day of admission until discharge from hospital, is measured through medical record review.
