Validity and Reliability of the Modified Delirium Diagnostic Tool - Provisional (DDT-Pro) (Thai Version) in Peri-operative Fragility Hip Fracture Patient

Nowadays, the number of hip fracture patients is increasing. As Thailand enters into an aging society, hip fractures are becoming more common. They are typically treated with surgery. Complications, such as urinary tract infections, pressure sores, and acute confusion, are often observed. These various complications contribute to an increased rate of illness and death.

Delirium is a common problem among hip fracture patients. Currently, diagnosis is typically made using the Diagnostic and Statistical Manual of Mental Disorders (DSM-V), which is a standard tool. However, utilizing it effectively requires expertise. Additionally, other tools such as the Confusion Assessment Method (CAM) and the Memorial Delirium Assessment Scale (MDAS) are available. Nonetheless, training is necessary for their proper use, and they may be more suitable for specific patient groups.

The Delirium Diagnostic Tool-Provisional (DDT-Pro) is another tool created to aid in diagnosing delirium. Unlike other tools, it does not require specialized training. It can assess the main symptoms of delirium, including cognitive ability, higher-level thinking skills, and the sleep-wake cycle. This tool has been utilized in foreign countries such as Spain. The tool was found to have good accuracy and reliability and is useful in aiding the diagnosis of delirium. However, it has never been translated and tested for use in elderly Thai patients with fragility hip fractures.

About this study

Inclusion criteria

Patients older than 65 years
Had a hip fracture within 7 days before receiving treatment at Siriraj Hospital
Received surgical treatment for a hip fracture

Exclusion criteria

Unable to communicate in Thai
Was diagnosed with cancer before or during treatment for a hip fracture
Have a history of schizophrenia
Patients infected with COVID-19

Primary outcomes include:

Validity: Conducting concurrent validity to examine the relationship between the Thai version of DDT-Pro and the Thai version of DSM-V using the 95% confidence interval (CI) for the AUC statistic.

Reliability: Determining the internal consistency of the tool through Cronbach's Alpha with a 95% confidence level, and assessing inter-rater reliability using the 95% CI for Kappa statistic.

Secondary outcomes include:

Prevalence of delirium in patients undergoing surgery for fragility hip fractures

Treatment and study plan

Delirium Diagnostic Tool-Provisional ( DDT-Pro )

Diagnostic Test

The Delirium Diagnostic Tool-Provisional (DDT-Pro) is another tool created to assist in the diagnosis of delirium. It does not require specialist expertise. It can assess the main symptoms of acute confusion, including cognitive ability (Cognition), higher-level thinking skills (Higher level thinking), and the sleep-wake cycle (Sleep-wake cycle).

Primary outcomes

To evaluate the accuracy and reliability of the revised Thai language version of the Delirium Diagnostic Tool-Provisional (DDT-Pro).

Time frame: 3 day

Accuracy and reliability of the revised Thai language version of the Delirium Diagnostic Tool-Provisional (DDT-Pro) compared with the gold standard tool (DSM V)

Secondary outcomes

The incidence of delirium in patients with fragility hip fractures before and after surgical treatment.

Time frame: 3 day

Number of delirium in peri-operative fragility hip fracture in Siriraj hospital
