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.
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.

The ICP medication algorithms first trial begins with: * Risperidone titrated to a max dose Failure to Risperidone will lead to a second trial with either: * Quetiapine OR Aripiprazole If subject refuses or if this trial does not work, then offer: * Ziprasidone or Loxapine Failure of 2 anti-psychotic trials results in: * Clozapine trial If subject refuses a Clozapine trial then: * Olanzapine offered titrations occur over 33-36 day period (inpatient) or 12 week period (out patient) with each 0.5 mg titration after the target dose requiring a CGI-E If compliance is an issue then a depot preparation: * Paliperidone * Risperidone * Flupentixol * Aripiprazole Physicians will be prompted for non-pharmacological interventions
The TAU group will be offered non-pharmacological interventions such as (but not limited to): * metabolic monitoring * skin hygiene * pain management * nutritional counseling * family counselling * Financial/housing support * Group CBT (Cognitive Behavioral Therapy) Physicians treating this group will use their own discretion as they will not be prompted like the ICP group. Pharmacological interventions contain anti-psychotic medication selected at the discretion of the treating physician provided it fall under the current standard of care such as: * Risperidone * Aripiprazole * Quetiapine * Olanzapine * Paliperidone * Clozapine * Ziprasidone Max dosing and the time to reach the target dose is done at the discretion of the treating physician.

Efficacy of LLS-ICP using a medication algorithm and evaluating with the clinical global impression severity scale (CGI-S) and brief psychiatric rating scale (BPRS)
Reduction in symptom severity will be measured using CGI-S (1 item 7 point scale with 0 being not assessed and 7 being most extremely ill patient) and (BPRS) which will be used to measure psychiatric symptoms such as hallucinations, anxiety or depression. ( 24 question scale rated from 0 being not assessed and 7 being extremely severe). Both scores will be aggregated to determine the reduction in overall symptoms and their severity in relationship to ICP and TAU groups.
Time frame: 18 months
Efficacy of an Integrated Care Pathway on rate and time of response needed to treat acute psychotic episode measured by CGI-E for therapeutic response and global improvement.
Reduction in the rate and time to respond to medication during an acute psychotic episode measured by Clinical global impression - efficacy scale (4 item scale rated from 0 - 4 points with 0 being not assessed and 4 representing side effects outweighing therapeutic effect). This scale will be used to measure the efficacy of therapeutic response to the medication algorithm in the ICP against the standard treatment of care (TAU).
Time frame: 18 months
Efficacy of an Integrated Care Pathway on side effect burden using Simpson Angus Scale (SAS), Barnes Akathisia Scale (BAS/BARS), and Abnormal Involuntary Movement Scale (AIMS).
Reduction in the number and severity of medication side effects on participants. The SAS is a 10 item scale (0 stands for normal - 4 stands for exaggerated symptoms) used to assess Parkinsonian and extra-pyramidal side effects. BAS is a 4 item scale used to assess the severity of drug induced akathisia. AIMS is a 12 item scale (0 for normal - 4 for severe) used to assess dyskinesias. These scores will be aggregated to measure the side effect burden seen with use of atypical anti-psychotic medication used to treat schizophrenia. These scores will compare the side effect burden of the TAU group against the ICP group.
Time frame: 18 months
Efficacy of an Integrated Care Pathway on functional outcome using the Multnomah Community Ability Scale (MCAS) for social functioning and Montreal Cognitive Assessment scale (MoCA) to test for cognition.
Increase in functional outcome to be assessed using the MCAS which measures adaptive functioning including health, adjustment to living, social competence and behavioral problems. It is a 17 item scale which graded from 1-6 where 1 represents extreme impairment, 5 represents normal and 6 representing unknown. The MoCA is a cognitive test that contains 12 items and is scored on a 30 point scale where 30 represents excellent cognitive function and 0 represents very poor cognitive function. Both scales will be aggregated to determine the relationship of the ICP and TAU to functional outcomes by measuring both cognitive and social functioning.
