Improving treatment of patients with psychosis in low-and-middle-income countries in Southeast Europe: Results from a hybrid effectiveness-implementation, pragmatic, cluster-randomized clinical trial (IMPULSE)

Background

In Southeast Europe (SEE) standard treatment of patients with psychosis is largely based on pharmacotherapy with psychosocial interventions rarely available. DIALOG+ is a digital psychosocial intervention designed to make routine care therapeutically effective. This trial simultaneously examined effectiveness of DIALOG+ versus standard care on clinical and social outcomes (Aim 1) and explored intervention fidelity (Aim 2).

Methods

A hybrid type II effectiveness–implementation, cluster-randomized trial was conducted in five SEE countries: Bosnia and Herzegovina, Kosovo*, Montenegro, North Macedonia, and Serbia. The intervention was offered to patients six times across 12 months instead of routine care. The outcomes were subjective quality of life (primary), clinical symptoms, satisfaction with services, and economic costs. Intervention fidelity was operationalized as adherence to the protocol in terms of frequency, duration, content, and coverage. Data were analyzed using multilevel regression.

Results

A total of 81 clinicians and 468 patients with psychosis were randomized to DIALOG+ or standard care. The intervention was delivered with high fidelity. The average number of delivered sessions was 5.5 (SD = 2.3) across 12 months. Patients in the intervention arm had better quality of life (MANSA) at 6 months (p = 0.03). No difference was found for other outcomes at 6 months. Due to disruptions caused by the COVID-19 pandemic, 12-month data were not interpretable.

Conclusions

DIALOG+ improved subjective quality of life of individuals with psychosis at 6 months (after four sessions), albeit with small effect size. The intervention has the potential to contribute to holistic care of patients with psychosis.

A non-randomised pilot study of the Solutions for Medication Adherence Problems (S-MAP) intervention in community pharmacies to support older adults adhere to multiple medications

BACKGROUND

Older patients prescribed multiple medications commonly experience difficulties with adherence. High-quality evidence on interventions targeting older patients is lacking. Theory is rarely used to tailor adherence solutions. This study aimed to pilot test a novel intervention, developed using the Theoretical Domains Framework, which guides community pharmacists in identifying adherence barriers and delivering tailored solutions (behaviour change techniques). Key study procedures (e.g. recruitment, data collection) for a future randomised controlled trial (cRCT) were also assessed.

METHODS

Using purposive sampling, this non-randomised pilot study aimed to recruit 12 community pharmacies (six in Northern Ireland; six in London, England). Pharmacists were trained to deliver the intervention to non-adherent older patients (maximum 10 per pharmacy; target n = 60-120) aged ≥ 65 years (reduced to 50 years due to recruitment challenges) and prescribed ≥ 4 regular medicines. The intervention, guided by an iPad web-application, was delivered over 3-4 face-to-face or telephone sessions, tailored to specific barriers to adherence. We assessed the feasibility of collecting adherence data (primary outcome: self-report and dispensing records), health-related quality of life (HRQOL) and unplanned hospitalisations (secondary outcomes) at baseline and 6-months. The final decision on progressing to a cRCT, using pre-defined 'stop-amend-go' criteria, is presented.

RESULTS

Fifteen pharmacists from 12 pharmacies were recruited and trained. One pharmacy subsequently dropped out. Sixty patients were recruited (meeting the 'Amend' progression criteria), with 56 receiving the intervention. Adherence barriers were identified for 55 patients (98%) and a wide range of behaviour change solutions delivered (median: 5 per patient). Self-report and dispensing adherence data were available for 37 (61.7%) and 44 (73.3%) patients, respectively. HRQOL data were available for 35 (58.3%) patients. GP-reported and self-reported hospitalisations data were available for 47 (78.3%) and 23 (38.3%) patients, respectively. All progression concepts were met (nine 'Go' and three 'Amend' criteria).

CONCLUSION

This study demonstrates the feasibility of key study procedures (e.g. pharmacy recruitment) and delivery of a tailored adherence intervention in community pharmacies. However, modifications are required to enhance issues identified with patient recruitment, retention and missing data. A future definitive cRCT will explore the effectiveness of the intervention.

A pilot study of the S-MAP (Solutions for Medications Adherence Problems) intervention for older adults prescribed polypharmacy in primary care: study protocol

Background

Adhering to multiple medications as prescribed is challenging for older patients (aged ≥ 65 years) and a difficult behaviour to improve. Previous interventions designed to address this have been largely complex in nature but have shown limited effectiveness and have rarely used theory in their design. It has been recognised that theory (‘a systematic way of understanding events or situations’) can guide intervention development and help researchers better understand how complex adherence interventions work. This pilot study aims to test a novel community pharmacy-based intervention that has been systematically developed using the Theoretical Domains Framework (12-domain version) of behaviour change.

Methods

As part of a non-randomised pilot study, pharmacists in 12 community pharmacies across Northern Ireland (n = 6) and London, England (n = 6), will be trained to deliver the intervention to older patients who are prescribed ≥ 4 regular medicines and are non-adherent (self-reported). Ten patients will be recruited per pharmacy (n = 120) and offered up to four tailored one-to-one sessions, in the pharmacy or via telephone depending on their adherence, over a 3–4-month period. Guided by an electronic application (app) on iPads, the intervention content will be tailored to each patient’s underlying reasons for non-adherence and mapped to the most appropriate solutions using established behaviour change techniques. This study will assess the feasibility of collecting data on the primary outcome of medication adherence (self-report and dispensing data) and secondary outcomes (health-related quality of life and unplanned hospitalisations). An embedded process evaluation will assess training fidelity for pharmacy staff, intervention fidelity, acceptability to patients and pharmacists and the intervention’s mechanism of action. Process evaluation data will include audio-recordings of training workshops, intervention sessions, feedback interviews and patient surveys. Analysis will be largely descriptive.

Discussion

Using pre-defined progression criteria, the findings from this pilot study will guide the decision whether to proceed to a cluster randomised controlled trial to test the effectiveness of the S-MAP intervention in comparison to usual care in community pharmacies. The study will also explore how the intervention components may work to bring about change in older patients’ adherence behaviour and guide further refinement of the intervention and study procedures.

Barriers to and enablers of diabetic retinopathy screening attendance: a systematic review of published and grey literature

AIMS

To identify and synthesize studies reporting modifiable barriers/enablers associated with retinopathy screening attendance in people with Type 1 or Type 2 diabetes, and to identify those most likely to influence attendance.

METHODS

We searched MEDLINE, EMBASE, PsycINFO, Cochrane Library and the 'grey literature' for quantitative and qualitative studies to February 2017. Data (i.e. participant quotations, interpretive summaries, survey results) reporting barriers/enablers were extracted and deductively coded into domains from the Theoretical Domains Framework; with domains representing categories of theoretical barriers/enablers proposed to mediate behaviour change. Inductive thematic analysis was conducted within domains to describe the role each domain plays in facilitating or hindering screening attendance. Domains that were more frequently coded and for which more themes were generated were judged more likely to influence attendance.

RESULTS

Sixty-nine primary studies were included. We identified six theoretical domains ['environmental context and resources' (75% of included studies), 'social influences' (51%), 'knowledge' (51%), 'memory, attention, decision processes' (50%), 'beliefs about consequences' (38%) and 'emotions' (33%)] as the key mediators of diabetic retinopathy screening attendance. Examples of barriers populating these domains included inaccurate diabetic registers and confusion between routine eye care and retinopathy screening. Recommendations by healthcare professionals and community-level media coverage acted as enablers.

CONCLUSIONS

Across a variety of contexts, we found common barriers to and enablers of retinopathy screening that could be targeted in interventions aiming to increase screening attendance.

Prioritizing research areas for antibiotic stewardship programmes in hospitals: a behavioural perspective consensus paper

SCOPE

Antibiotic stewardship programmes (ASPs) are necessary in hospitals to improve the judicious use of antibiotics. While ASPs require complex change of key behaviours on individual, team organization and policy levels, evidence from the behavioural sciences is underutilized in antibiotic stewardship studies across the world, including high-income countries (HICs). A consensus procedure was performed to propose research priority areas for optimizing effective implementation of ASPs in hospital settings using a behavioural perspective.

METHODS

A workgroup for behavioural approaches to ASPs was convened in response to the fourth call for leading expert network proposals by the Joint Programming Initiative on Antimicrobial Resistance (JPIAMR). Eighteen clinical and academic specialists in antibiotic stewardship, implementation science and behaviour change from four HICs with publicly funded healthcare systems (e.g. Canada, Germany, Norway and the UK) met face-to-face to agree on broad research priority areas using a structured consensus method. Question addressed and recommendations: The consensus process assessing the ten identified research priority areas resulted in recommendations that need urgent scientific interest and funding to optimize effective implementation of ASPs for hospital inpatients in HICs with publicly funded healthcare systems. We suggest and detail behavioural science evidence-guided research efforts in the following areas: (a) comprehensively identifying barriers and facilitators to implementing ASPs and clinical recommendations intended to optimize antibiotic prescribing; (b) identifying actors ('who') and actions ('what needs to be done') of ASPs and clinical teams; (c) synthesizing available evidence to support future research and planning for ASPs; (d) specifying the activities in current ASPs with the purpose of defining a control group for comparison with new initiatives; (e) defining a balanced set of outcomes and measures to evaluate the effects of interventions focused on reducing unnecessary exposure to antibiotics; (f) conducting robust evaluations of ASPs with built-in process evaluations and fidelity assessments; (g) defining and designing ASPs; (h) establishing the evidence base for impact of ASPs on resistance; (i) investigating the role and impact of government and policy contexts on ASPs; and (j) understanding what matters to patients in ASPs in hospitals.

CONCLUSIONS

Assessment, revisions and updates of our priority-setting exercise should be considered at intervals of 2 years. To propose research priority areas in low- and middle-income countries, the methodology reported here could be applied.

Molecular investigation of Mycoplasma haemofelis in stray cats in Kota Bharu, Kelantan

Mycoplasma haemofelis (M. haemofelis) is a gram-negative, epicellular bacteria that infects feline red cells (RBC). The pathogen appears as small blue cocci, rings, or rods on the edges or across the surface of RBCs and often causes haemolytic anemia. However, the epizootiology of M. haemofelis is still poorly understood. So far, there are only a few studies that have been carried out to determine the prevalence of M. haemofelis. Most of the studies were conducted in Europe and other continents and the epidemiology of M. haemofelis in Malaysia, particularly in stray cats have not been reported. In this study, 60 blood samples were collected from stray cats in Kota Bharu and were examined by using thin blood smear and polymerase chain reaction (PCR) methods. This study showed that seven out of the 60 blood samples were positive for M. haemofelis by using PCR. Thus the prevalence rate of M. haemofelis in stray cats in Kota Bharu from this study was 11.7%. However, more studies with larger sample size and diverse sample distribution should be conducted to better understand the occurrence of this pathogen in both housed and stray cats. Moreover, the genetic variability of M. haemofelis infecting domestic and wild animals need to be conducted to verify the relationship among geographic distribution, genetic diversity and the potential threats to animal and human health.

Beliefs about responsibilities, the aims of therapy and the structure of the therapy process: a qualitative study of caseload management issues in child health occupational therapy

BACKGROUND

Individual therapists' behaviour contributes to overall caseload management in therapy services. Therapists' caseload management (i.e. actions in relation to assessment, treatment and discharging) is likely to relate to their beliefs about caseload management; it may be possible to change therapists' caseload management by changing their beliefs. This study explored children's occupational therapists' beliefs about caseload management with a view to designing a caseload management intervention.

METHODS

Twenty-five therapists from six NHS Scotland Health Boards were interviewed using a semi-structured format. Interviews were transcribed verbatim, and the interview transcripts were analysed for emerging themes. A proportion of transcripts were independently read and coded, and the themes were validated through critical discussion.

RESULTS

Key issues emerged concerning therapists' beliefs about their responsibilities, the aims of therapy and the structure of the therapy process. Therapists expressed a strong sense of professional duty/responsibility, but the interpretations of what this duty/responsibility was differed between therapists. For example, therapists expressed highly contrasting beliefs about the goals and purpose of therapy and the ways in which therapy processes should be structured. Some therapists promoted an approach structured around clients' goals, while others focused more on relationship building.

CONCLUSIONS

Therapists' beliefs about caseload management differ considerably; these differences could translate to variation in therapists' intentions and behaviours. Implications for practice, policy and future research were identified, as were implications for the way clinicians' caseload management is theorized.

Patient satisfaction associated with correct identification of physician's photographs

OBJECTIVE

To determine whether placement of photographs of physicians in hospital rooms improves patients' satisfaction with their medical care.

PATIENTS AND METHODS

This is a prospective, controlled study of 224 patients admitted to general internal medicine services in a teaching hospital. The intervention consisted of photographs (8 x 10 in) of attending and resident physicians displayed in the patients' rooms. Before dismissal, patients completed a survey that required them to match names with photographs of physician caregivers and included patient satisfaction questions. The primary outcome was whether patients who had photographs in their hospital room would correctly identify more physicians than those with no photographs in their room.

RESULTS

The presence of photographs on the hospital wall was associated with a significant improvement in the number of physicians identified correctly (odds ratio [OR], 1.83; 95% confidence interval [CI], 1.47-2.27; P<.001). The percentage of physicians that patients identified by correctly matching their physicians' names to their photographs was significantly associated with satisfaction with physician responsiveness (OR, 1.19; 95% CI, 1.01-1.40; P=.03) and with the way in which physicians addressed questions regarding medical care (OR, 1.23; 95% CI, 1.05-1.44; P=.05).

CONCLUSIONS

Patients who had photographs of their physicians on the wall of their hospital room were able to identify correctly a larger number of physicians on their team compared with patients who had no photographs. Patient satisfaction was related to the number of physicians' photographs that patients could identify correctly.

Softgels: consumer perceptions and market impact relative to other oral dosage forms

Softgels, which contain a liquid formulation of a drug, often provide clinical benefit over other solid oral dosage forms and may represent an attractive alternative to them. A consumer preference survey of softgels versus other solid forms investigated four areas: (1) identification of various dosage forms; (2) perception of therapeutic benefit (easiest to swallow, faster-acting, work longer); (3) impact of individual product characteristics on overall product selection; and (4) market impact in terms of premiums consumers would pay on the basis of dosage form. The 300 survey participants strongly preferred clear softgels over other dosage forms in virtually every area. Softgels were perceived as easy to swallow and fast-acting, with a duration of action second only to that of a two-piece capsule. Overall preference was driven by ease of swallowing, and softgels were rated first by the majority of respondents. Consumers would be interested in various products if these were available as softgels rather than in their current oral dosage forms and may be willing to pay a premium for softgel products. This survey confirms consumer preferences for particular dosage forms and for softgels over other solid forms. Pharmaceutical scientists and marketers should consider softgels as alternative dosage forms when developing new compounds or considering life-cycle management of existing products.

NACOB presentation to ASB Young Scientist Award: Postdoctoral. The impact of boundary conditions and mesh size on the accuracy of cancellous bone tissue modulus determination using large-scale finite-element modeling. North American Congress on Biomechanics

The apparent properties of cancellous bone are determined by a combination of both hard tissue properties and microstructural organization. A method is desired to extract the underlying hard tissue properties from simple mechanical tests, free from the complications of microstructure. It has been suggested that microCT voxel-based large-scale finite element models could be employed to accomplish this goal (van Rietbergen et al., 1995, Journal of Biomechanics, 28, 69-81). This approach has recently been implemented and it is becoming increasingly popular as finite element models increase in size and sophistication (Fyhrie et al., 1997, Proceedings of the 43rd Annual Meeting of the Orthopaedic Research Society, San Francisco, CA, p. 815; van Rietbergen et al., 1997, Proceedings of the 43rd Annual Meeting of the Orthopaedic Research Society, San Francisco, CA, p. 62). However, no direct quantitative measurements of the accuracy of this method applied to porous structures such as cancellous bone have been made. This project demonstrates the feasibility of this approach by quantifying its best-case accuracy in determining the trabecular hard tissue modulus of analogues fabricated of a material with known material properties determined independently by direct testing. In addition we were able to assess the impact of mesh size and boundary conditions on accuracy. We found that the assumption of a frictionless boundary condition in the parallel plate compression loading configuration was a significant source of error that could be overcome with the use of rigid end-caps similar to those used by Keaveny et al. (1997 Journal of Orthopaedic Research, 15(1), 101-110). In conclusion, we found that this approach is an effective method for determining the average trabecular hard tissue properties of human cancellous bone with an expected practical accuracy level better than 5%.
