About

As of late Integrated Care Pathways (ICPs) have been shown to improve quality of care in the medical field with special attention given to mental health in particular. One aspect of metal health that has not seen the incorporation of ICPs is in the area of schizophrenia. Late life Schizophrenia (LLS) is defined as suffering from schizophrenia and being 50 years of age or older. The LLS-ICP study will look at the efficacy of an ICP in late life schizophrenia versus treatment as usual (TAU). Participants with LLS and having psychotic symptoms above a predefined threshold will be randomly assigned to a TAU group or an ICP group. The primary outcome measure will be reduction in symptom severity as measured by clinical global impression severity scale (CGI-S) and brief psychiatric rating scale (BPRS). If successful, this study will provide strong evidence to implement LLS-ICP across different inpatient and outpatient settings.

Full description

This study aims to investigate whether a Late-Life Schizophrenia-Integrated Care Pathway (LLS-ICP) is superior to treatment as usual (TAU) in the treatment of psychotic symptoms of patients with schizophrenia or schizoaffective disorder. The investigators hypothesize that the LLS-ICP will be superior to TAU and result in 1.higher rates of response, 2. shorter times to response, 3. less side effects, 4. and better functional outcomes. The LLS-ICP study will be the first randomized controlled study to assess the efficacy of an ICP in patients with schizophrenia or schizoaffective disorder in this region. If successful, it will lead to the development of new and innovative approaches to health care delivery to patients with chronic schizophrenia or schizoaffective disorder not just within this institution but also at other sites in the community. The nature of ICPs as algorithmic and systematic in providing assessments and treatments render them ideal to be disseminated to medical practice outside of the institution of where they have been developed. These settings can include primary care clinics, supportive living environments, and long-term care homes where patients with chronic schizophrenia or schizoaffective disorder are being cared for.

24 participants in 2 patient groups

Late-life Schizophrenia ICP

Active Comparator group

Description:

The Late-Life Schizophrenia ICP arm will follow a medication algorithm composed of 3 trials and titration schedule with prompts. First trial is Risperidone (2- 4mg daily). Second trial: Quetiapine (100 - 400mg daily) OR Aripiprazole (100 - 200mg daily) OR OR Ziprasidone (80mg daily) OR Loxapine (100mg daily) Third trial: Clozapine (450mg daily) or Olanzapine (20mg daily) If non compliant depot preparation of: Paliperidone (50 - 150mg monthly), Risperidone (12.5 - 50mg q 2 weeks), Flupentixol (10 - 20mg q 2-3 weeks) or Aripiprazole ( up to 400mg monthly) Prompts will be given to for non-pharmacological interventions such as: * metabolic monitoring * skin hygiene * pain management * nutritional counseling * counseling

Treatment:

Other: Late-life Schizophrenia ICP

Treatment as Usual (TAU)

Active Comparator group

Description:

The TAU will not receive any prompts to follow a specific treatment. The TAU group will be treated according to the current standard of care by the treating physician. They will have an opportunity to be offered the same non-pharmacological interventions seen with the ICP group but at the discretion of the treating physician. Pharmacological interventions will include an anti-psychotic medication that is selected at the discretion of treating physician with no set titration schedule or timeline to meet a maximum dosage. Max dosage will be decided by the treating physician.
