Functionality
Distribution of patients achieving ≥ 1 change in Personal and Social Performance (PSP) Scale category at end point. Intent-to-treat population; PSP scale scores at end point for individual patients to show a clinically relevant change in personal and social functioning as represented by improvement of ≥ 1 category (classified as one 10-point interval); PSP = Personal and Social Performance Scale.

Criteria for Recovery?
• Symptom remission• Vocational functioning• Independent living• Peer relationships• Duration ≥ 2 years
Is recovery best viewed as an outcome or a process?

Recovery – A Matter of Perspective
• Recovery from Illness– Cure of illness, absence of illness
versus
• Recovery in Illness: being in recovery– Process of managing illness more effectively– Having a meaningful life in the community
– Moving ahead with one’s life despite illness

Factors Associated with the Potential for Positive Clinical and Functional Outcomes
• Short duration of untreated psychosis• Good early response to antipsychotic treatment• Collaborative therapeutic alliance• Supportive family/caregivers• Access to comprehensive, coordinated, and
continuous treatment• Opportunities to engage in functional activities
and receive specialized interventions• Absence of substance abuse
What about cognition in patients with
schizophrenia?
Cognitive Deficits Are the Bridge Between Brain Functioning and Functional Impairments
in Day-to-Day Life
• Cognitive deficits are a frequent and robust feature of the illness
• Cognitive deficits are present at illness onset and persist throughout the illness
• Cognitive deficits directly contribute to poor functional outcome in schizophrenia

Components of Psychosocial Rehabilitation
Outcomes• Functional • SubjectiveMotivational
Aspects• External• Intrinsic
Social Cognition• Emotion processing• Social perception• Attributional bias• Theory of mind
Neurocognition• Attention• Processing• Memory• Reasoning• Verbal learning• Visual learning
Kurzban S, et al. Curr Psychiatry Rep. 2010;12:345-355.
Cognitive Remediation• Behavioral treatments that specifically target:
– Memory– Attention– Executive functioning– Reasoning
• Restorative cognitive techniques – drill and practice– Paper & pencil tasks– Computerized training software
COGPACK, Posit Science Brain Fitness, etc.– Individual– Groups– Compensatory cognitive training – promote adaptive behavior
• Enhance daily functioning – School, work, social interactions, independent living
• Enhance skills pertinent to recovery goals
Medalia A, Choi J. Neuropsychol Rev. 2009;19:353-364.
Work and Schizophrenia
Barriers• Cognitive impairments• Psychiatric symptoms• Episodes of illness• Stigma from employers• Internalized stigma/low self-confidence• Fear of losing disability benefits
McGurk S, et al. Schizophr Bull. 2009;35:319-335.Kurzban S, et al. Curr Psychiatry Rep. 2010;12:345-355.

Vocational Rehabilitation
McGurk S, et al. Schizophr Bull. 2009;35:319-335.Kurzban S, et al. Curr Psychiatry Rep. 2010;12:345-355.
• Skills training• Sheltered workshops• Transitional employment• Supported employmentVocational rehabilitation + cognitive remediation → best
results
Employment =• Increased self esteem• Reduction in symptoms and hospitalizations• Enhanced social functioning• Improvement in overall quality of life
Supported EmploymentBasic Principles1. Zero exclusion; eligibility based on consumer choice2. Focus on competitive jobs in integrated community
settings3. Rapid job search4. Respect for consumers’ preferences in terms of the
nature of the job and types of support services5. Ongoing job support6. Close integration with a psychosocial rehabilitation
team approach7. Benefits counseling (disability benefits, social security,
medical insurance)

Real-World Antipsychotic Treatment Practices
Moore T, et al. Psychiatr Clin N Am. 2007;30:401-416.
• Second-generation antipsychotics are used in over 70% of individuals with schizophrenia (use may be higher in first-episode patients)
• Rate of clozapine use is much lower than the incidence of treatment-resistant schizophrenia
• Antipsychotic polypharmacy – ~10 to 30% of individuals with schizophrenia
– FGA + SGA most common combinations
• Use of adjunctive medications– Baseline data from CATIE
Antidepressants (38%), anxiolytics (22%), sedative hypnotics (19%), lithium (4%), other mood stabilizers (15%)
• Dosage of antipsychotic medications within therapeutic range 64 to 83% of the time during inpatient treatment
What do we know about efficacy and
tolerability of antipsychotic medication?

What Is Treatment Effectiveness?
TreatmentEffectiveness
Combines all measures
Effective Use of Medication
• Medication is a tool that a person with schizophrenia can use to take greater control over his or her life
• The goal should be to maximize the effectiveness of medication to help the person live the kind of life that he or she wants to live
• The medicine has work well enough, be tolerated well enough, and the patient has to take it
Medication Nonadherence
Lacro J, et al. J Clin Psychiatry. 2002;63:892-909.Novick D, et al. Psychiatry Res. 2010;176:109-113.Masand P, et al. Prim Care Companion J Clin Psychiatry. 2009;11:147-154.
• Prevalence ~30 to 50% (and higher); rates vary depending on clinical setting, definitions, study duration, study population
• Relatively short gaps in medication coverage can increase the risk of relapse
• Nonadherence is associated with poor outcomes–Relapse–Hospitalization–Suicide attempts
How can we manage non-adherence?
Step 1: Admit the possibility of partial or
nonadherence
We Overestimate Adherence
– Nonadherence viewed as failure → consistent bias to overestimate adherence/underestimate nonadherence
– We assume lack of adequate response as “treatment-resistance” and lack of efficacy for the antipsychotic for that patient This is a possible explanation for high dosing of antipsychotics,
polypharmacy with other antipsychotics and combination treatment with anticonvulsants – This is a no-win cycle: adherence is even more of a
challenge with complex regimens
Velligan DI, et al. Psychiatr Serv. 2007;58(9):1187-1192.
Step 2: Identify the specific barriers to
adherence present for your patient
Risk Factors for Nonadherence

Barriers to Therapeutic Alliancein Schizophrenia
● Patient barriers1
– Communication difficulties – Difficulty forming an alliance because of negative symptoms – Difficulty learning from experience because of cognitive
symptoms – Rejection of diagnosis due to stigma
● Clinician barriers2
– Underestimating importance of relationship – Hopelessness conveyed to patient – Lack of interest in life goals and other issues important to patient
1. Velligan DI, et al. J Clin Psychiatry. 2009;70(suppl 4):1-46.2. Pitschel-Walz, G, et al. J Clin Psychiatry. 2006;67(3):443-452.

Assessing Medication Adherence: Interview Style
● Ask for the patient’s view about medications1,2 ● Obtain sufficient information before responding3 ● Do not jump to conclusions; take comments at face value3
● Explain that you want to hear what the patient really thinks, not what he/she thinks you want to hear1-3
● If you want to respond, do not try to do too much and make sure you do not go beyond what the patient can accept for now
● As much as you can, try to keep the discussion about medication adherence positive—even enjoyable1
● Above all, try to maintain and even strengthen the alliance, even if there is disagreement about the need for medication1
1. Weiden, PJ. J Psychiatr Prac. 2002;8(6):386-392.2. McCabe R, et al. BMJ. 2002;325(7373):1148-1151.3. Weiden PJ. J Clin Psychiatry. 2007;68(suppl 14):14-19.
Assessing Medication Adherence: Interview Style
“Have you been taking your medications?” or “You have been taking your medicines, right?”
“Everyone misses doses of their medicines. Can you give me some idea of how many doses do you usually miss in any given week? I just need a ball-park figure, you don’t have to be exact.”
This is followed by, “What doses do you miss the most – morning? evening? with meals? in between meals? This way we can figure out the best time of day to use these medications so we can minimize the number of times you may miss them.”
Risk Factors for Nonadherence
1. Velligan DI, et al. J Clin Psychiatry. 2009;70(suppl 4):1-46.2. Lee S, et al. Soc Sci Med. 2006;62(7):1685-1696.

Medication-related Side Effects and Nonadherence
● Potential drivers– Level of distress rather than severity– Attribution to the medication– Vary from patient to patient
● Most commonly associated with nonadherence– Weight gain– Sedation– Akathisia– Sexual dysfunction– Parkinsonian symptoms– Cognitive problems
Velligan DI, et al. J Clin Psychiatry. 2009;70(suppl 4):1-46.

Considering Side Effect Profile When Choosing Treatment
Important because side effects may1:– Contribute to treatment nonadherence– Limit return to maximal levels of social functioning– Potentially contribute to long-term morbidity
Atypical antipsychotics are better tolerated than typical antipsychotics (mainly due to decreased EPS)2
Differences in drug-specific adverse effect profiles, including metabolic effects, may impact treatment adherence and long-term outcomes1,2

What Type of Intervention Is Appropriate?
● If the adherence problem is that the patient WILL NOT, focus intervention on strengthening perceived benefits of medication and minimizing perceived costs
● If the adherence problem is that the patient CANNOT, then address barriers to adherence
– Pill boxes in obvious locations – Self-monitoring tools– Establishment of routines– Consider long-acting injectable antipsychotic

Step 3: Monitoring adherence
Monitoring Medication Adherence● There are no entirely satisfactory methods, but can
count pills and measure plasma levels● Ask if the patient is taking his/her medications● Ask, are the medications doing any good?
– Any perceived benefit (eg, sleeping better) is a treasure
– If none, be worried● Ask, are the medications doing any harm?
– Ask about being sleepy, slowed down, dulled – Ask about weight changes – Ask about constipation – Ask about sex
Velligan DI, et al. J Clin Psychiatry. 2009;70(suppl 4):1-46.
Step 4: Consider a depot antipsychotic
Considering Efficacy When Choosing Treatment
Someone who isn’t responding adequately to an oral medication is unlikely to then respond to its depot formulation Unless they were a non-responder because of nonadherence
There is heterogeneity in efficacy outcomes among the different antipsychotics, and this heterogeneity is observed among groups in clinical trials and in individual patients
Potential Advantages of Long-acting Injectable Antipsychotics
Reduces dosage deviations1
Eliminates guessing about adherence status2,3
Shows start date of nonadherence2,3
Helps disentangle reasons for poor response to medication3
Eliminates need for the patient to remember to take a pill daily1
Enables prescribers to avoid first-pass metabolism, therefore a better relationship between dose and blood level exists1
Results in predictable and stable plasma levels1
Eliminates abrupt loss of efficacy if dose missed1,3
Many patients prefer them, especially if already receiving them4

Potential Obstacles to Long-acting Injectable Antipsychotics
Lack of infrastructure in outpatient settings Need to refrigerate, store, reconstitute, etc. Overburdened public agencies Frequency of injections and consequent inconvenience
for staff and patients Need to take concomitant medications orally Anti-shot sentiment

• Clinical practice guidelines can provide advice regarding a comprehensive approach, unfortunately not often done
• Treatment effectiveness is dependent on a medication being efficacious enough, tolerable enough, and the patient has to take it
• Adherence can be the ultimate confounder regarding effectiveness
