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

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

Work and Schizophrenia
~20% employed
80% Unemployed
Barriers
•
•
•
•
•
•
55–70% identify employment as a goal
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
• Skills training
• Sheltered workshops
• Transitional employment
• Supported employment
Vocational rehabilitation + cognitive remediation → best
results
Employment =
• Increased self esteem
• Reduction in symptoms and hospitalizations
• Enhanced social functioning
• Improvement in overall quality of life
McGurk S, et al. Schizophr Bull. 2009;35:319-335.
Kurzban S, et al. Curr Psychiatry Rep. 2010;12:345-355.
Supported Employment
Basic Principles
1. Zero exclusion; eligibility based on consumer choice
2. Focus on competitive jobs in integrated community
settings
3. Rapid job search
4. Respect for consumers’ preferences in terms of the
nature of the job and types of support services
5. Ongoing job support
6. Close integration with a psychosocial rehabilitation
team approach
7. Benefits counseling (disability benefits, social security,
medical insurance)

Treatment Practices
• 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

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
• 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
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.
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

Barriers to Therapeutic Alliance
in 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.

Poor
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
●

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.”

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

● 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

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

Adherence Summary
 Strategies to improve adherence include
– Admitting that partial or nonadherence is a possibility
– Identifying risk factors specific to the individual
– Addressing barriers to therapeutic alliance
– Tailoring interventions to adherence attitudes and
behavior
 Pharmacologic strategies to improve adherence include
– Considering patient history, efficacy, and side effect
profile when choosing treatment
– Considering utilizing long-acting injectable
antipsychotics, if available, in patients with recurring
relapses related to nonadherence
Summary
• Response, remission and recovery are necessary goals of
treatment, but each can be interpreted differently by
clinicians, patients, and their families
• 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
