Barriers to the management of sexual dysfunction among people with psychosis: analysis of qualitative data from the REMEDY trial.

BACKGROUND: More than half of people who use antipsychotic medication for psychosis report having sexual dysfunction. The REMEDY trial aimed to find out if switching antipsychotic medication provides an effective way to reduce sexual dysfunction among people with psychosis. We set out to recruit 216 participants over a two-year period, but recruitment was stopped after an extended 12-month pilot phase, during which we recruited only 10 participants. As part of a nested process evaluation, we conducted qualitative interviews with front-line clinicians to examine barriers to recruitment to the trial. METHODS: We developed a semi-structured interview schedule to explore staff views on factors that influenced whether they referred potential participants to the study. We interviewed a purposive sample of 51 staff from four National Health Service (NHS) Trusts in England, ensuring a range of different backgrounds, seniority, and levels of involvement in the trial. Audio recordings of interviews were transcribed for verbatim, and data were analysed using an inductive approach to thematic analysis. RESULTS: Nine interconnected themes were generated. Six themes concerned barriers to recruitment; including; prioritising patients' mental stability, mutual discomfort and embarrassment about discussing a "taboo" subject, and concerns about unintended consequences of asking people with psychosis about their sexual functioning. Three themes, including the quality of treatment relationships and strategies for opening dialogue suggested ways to improve recognition of these "hidden" side effects. CONCLUSION: The identification and management of sexual dysfunction among people with psychosis are not priorities for mental health services in England at this time. Many staff working in front-line services feel unprepared and uncomfortable asking people with psychosis about these problems. While greater use of screening tools may improve the identification of sexual dysfunction among people with psychosis, the evaluation and implementation of interventions to manage them will continue to be challenging unless NHS leaders and senior clinicians demonstrate greater commitment to changing current clinical practice.

Switching antipsychotic medication to reduce sexual dysfunction in people with psychosis: the REMEDY RCT.

BACKGROUND: Sexual dysfunction is common among people who are prescribed antipsychotic medication for psychosis. Sexual dysfunction can impair quality of life and reduce treatment adherence. Switching antipsychotic medication may help, but the clinical effectiveness and cost-effectiveness of this approach is unclear. OBJECTIVE: To examine whether or not switching antipsychotic medication provides a clinically effective and cost-effective method to reduce sexual dysfunction in people with psychosis. DESIGN: A two-arm, researcher-blind, pilot randomised trial with a parallel qualitative study and an internal pilot phase. Study participants were randomised to enhanced standard care plus a switch of antipsychotic medication or enhanced standard care alone in a 1 : 1 ratio. Randomisation was via an independent and remote web-based service using dynamic adaptive allocation, stratified by age, gender, Trust and relationship status. SETTING: NHS secondary care mental health services in England. PARTICIPANTS: Potential participants had to be aged ≥ 18 years, have schizophrenia or related psychoses and experience sexual dysfunction associated with the use of antipsychotic medication. We recruited only people for whom reduction in medication dosage was ineffective or inappropriate. We excluded those who were acutely unwell, had had a change in antipsychotic medication in the last 6 weeks, were currently prescribed clozapine or whose sexual dysfunction was believed to be due to a coexisting physical or mental disorder. INTERVENTIONS: Switching to an equivalent dose of one of three antipsychotic medications that are considered to have a relatively low propensity for sexual side effects (i.e. quetiapine, aripiprazole or olanzapine). All participants were offered brief psychoeducation and support to discuss their sexual health and functioning. MAIN OUTCOME MEASURES: The primary outcome was patient-reported sexual dysfunction, measured using the Arizona Sexual Experience Scale. Secondary outcomes were researcher-rated sexual functioning, mental health, side effects of medication, health-related quality of life and service utilisation. Outcomes were assessed 3 and 6 months after randomisation. Qualitative data were collected from a purposive sample of patients and clinicians to explore barriers to recruitment. SAMPLE SIZE: Allowing for a 20% loss to follow-up, we needed to recruit 216 participants to have 90% power to detect a 3-point difference in total Arizona Sexual Experience Scale score (standard deviation 6.0 points) using a 0.05 significance level. RESULTS: The internal pilot was discontinued after 12 months because of low recruitment. Ninety-eight patients were referred to the study between 1 July 2018 and 30 June 2019, of whom 10 were randomised. Eight (80%) participants were followed up 3 months later. Barriers to referral and recruitment included staff apprehensions about discussing side effects, reluctance among patients to switch medication and reticence of both staff and patients to talk about sex. LIMITATIONS: Insufficient numbers of participants were recruited to examine the study hypotheses. CONCLUSIONS: It may not be possible to conduct a successful randomised trial of switching antipsychotic medication for sexual functioning in people with psychosis in the NHS at this time. FUTURE WORK: Research examining the acceptability and effectiveness of adjuvant phosphodiesterase inhibitors should be considered. TRIAL REGISTRATION: Current Controlled Trials ISRCTN12307891.

Antipsychotic medications can improve the mental health of people with psychosis but may also cause side effects. These include sexual side effects, such as reduced desire for sex or less pleasure from having sex. One way to try to tackle this problem is to switch the medicine people take to one that is thought less likely to cause these problems. However, it is unclear if this helps, and switching medication could potentially harm mental health or cause new side effects. We conducted a study to compare the effect of switching with not switching the medication of people with psychosis experiencing sexual side effects. We collected information about sexual functioning, mental health, quality of life and use of services at the start of the study and 6 months later. We also interviewed nurses, doctors and patients to get their views about the study. We recruited 10 patients over a 12-month period and conducted interviews with 51 clinicians and four patients. Many clinicians said that they found it difficult to talk to their patients about sex. Some thought that these problems occurred rarely and that other side effects mattered more to patients. Many patients were concerned about switching their medication, especially when it had improved their mental health. Others felt that these side effects were not very important, and some were not prepared to take part in a trial that could delay a change being made to their medication. We did not collect enough information to be able to find out if switching medication helps people who experience sexual side effects of antipsychotic drugs. It is important that clinicians ask about sexual side effects of antipsychotic medication and that further efforts are made to find ways to help patients who experience them.

Development and Psychometric Properties of the Standardized Assessment of Severity of Personality Disorder (SASPD).

Personality disorder (PD) is increasingly categorized according to its severity, but there is no simple way to screen for severity according to ICD-11 criteria. We set out to develop the Standardized Assessment of Severity of Personality Disorder (SASPD). A total of 110 patients completed the SASPD together with a clinical assessment of the severity of personality disorder. We examined the predictive ability of the SASPD using the area under the ROC curve (AUC). Two to four weeks later, 43 patients repeated the SASPD to examine reliability. The SASPD had good predictive ability for determining mild (AUC = 0.86) and moderate (AUC = 0.84) PD at cut points of 8 and 10, respectively. Test-retest reliability of the SASPD was high (intraclass correlation coefficient = 0.93, 95% CI [0.88, 0.96]). The SASPD thus provides a simple, brief, and reliable indicator of the presence of mild or moderate PD according to ICD-11 criteria.
