Interventions to improve retention in a surgical, clinical trial: A pragmatic, stakeholder-driven approach

'It's just a finger isn't it…': patients' perspectives of recovery following finger fractures and participation in surgical trials - a qualitative interview study

OBJECTIVES

To (1) generate detailed, person-centred data about the experience of finger injury and treatment and (2) understand the patients' perspectives of research involvement with a view to informing better designed future studies in hand injury.

DESIGN

Qualitative study using semistructured interviews and framework analysis.

PARTICIPANTS

19 participants who were part of the Cohort study of Patients' Outcomes for Finger Fractures and Joint Injuries study in a single secondary care centre in the UK.

RESULTS

The results of this study showed that although finger injuries are frequently seen as minor by patients and healthcare professionals, their effects on peoples' lives are possibly greater than first anticipated. The relative importance of hand functioning means that the experience of treatment and recovery varies and is shaped by an individual's age, job, lifestyle and hobbies. These factors will also inform an individual's perspective on and willingness to participate in, hand research. Interviewees showed reluctance to accept randomisation in surgical trials. Interviewees would be more likely to participate in a study testing two variants of the same treatment modality (eg, surgery vs surgery), rather than two different modalities, (eg, surgery vs splint). The Patient-Reported Outcome Measure questionnaires that were used in this study were seen as less relevant by these patients. Pain, hand function and cosmetic appearance were considered important, meaningful outcomes.

CONCLUSIONS

Patients with finger injuries need more support from healthcare professionals as they may experience more problems than first anticipated. Good communication by clinicians and empathy can help patients engage with the treatment pathway. Perceptions of an 'insignificant' injury and/or need for quick functional recovery will influence recruitment to future hand research (both positively and negatively). Accessible information about the functional and clinical consequences of a hand injury will be important in enabling participants to make fully informed decisions about participation.

Strategies to improve retention in randomised trials

BACKGROUND

Poor retention of participants in randomised trials can lead to missing outcome data which can introduce bias and reduce study power, affecting the generalisability, validity and reliability of results. Many strategies are used to improve retention but few have been formally evaluated.

OBJECTIVES

To quantify the effect of strategies to improve retention of participants in randomised trials and to investigate if the effect varied by trial setting.

SEARCH METHODS

We searched the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, Scopus, PsycINFO, CINAHL, Web of Science Core Collection (SCI-expanded, SSCI, CPSI-S, CPCI-SSH and ESCI) either directly with a specified search strategy or indirectly through the ORRCA database. We also searched the SWAT repository to identify ongoing or recently completed retention trials. We did our most recent searches in January 2020.

SELECTION CRITERIA

We included eligible randomised or quasi-randomised trials of evaluations of strategies to increase retention that were embedded in 'host' randomised trials from all disease areas and healthcare settings. We excluded studies aiming to increase treatment compliance.

DATA COLLECTION AND ANALYSIS

We extracted data on: the retention strategy being evaluated; location of study; host trial setting; method of randomisation; numbers and proportions in each intervention and comparator group. We used a risk difference (RD) and 95% confidence interval (CI) to estimate the effectiveness of the strategies to improve retention. We assessed heterogeneity between trials. We applied GRADE to determine the certainty of the evidence within each comparison.

MAIN RESULTS

We identified 70 eligible papers that reported data from 81 retention trials. We included 69 studies with more than 100,000 participants in the final meta-analyses, of which 67 studies evaluated interventions aimed at trial participants and two evaluated interventions aimed at trial staff involved in retention. All studies were in health care and most aimed to improve postal questionnaire response. Interventions were categorised into broad comparison groups: Data collection; Participants; Sites and site staff; Central study management; and Study design. These intervention groups consisted of 52 comparisons, none of which were supported by high-certainty evidence as determined by GRADE assessment. There were four comparisons presenting moderate-certainty evidence, three supporting retention (self-sampling kits, monetary reward together with reminder or prenotification and giving a pen at recruitment) and one reducing retention (inclusion of a diary with usual follow-up compared to usual follow-up alone). Of the remaining studies, 20 presented GRADE low-certainty evidence and 28 presented very low-certainty evidence. Our findings do provide a priority list for future replication studies, especially with regard to comparisons that currently rely on a single study.

AUTHORS' CONCLUSIONS

Most of the interventions we identified aimed to improve retention in the form of postal questionnaire response. There were few evaluations of ways to improve participants returning to trial sites for trial follow-up. None of the comparisons are supported by high-certainty evidence. Comparisons in the review where the evidence certainty could be improved with the addition of well-done studies should be the focus for future evaluations.

Surgical fixation compared with cast immobilisation for adults with a bicortical fracture of the scaphoid waist: the SWIFFT RCT

BACKGROUND

Scaphoid fractures account for 90% of carpal fractures and occur predominantly in young men. Immediate surgical fixation of this fracture has increased.

OBJECTIVE

To compare the clinical effectiveness and cost-effectiveness of surgical fixation with cast treatment and early fixation in adults with scaphoid waist fractures that fail to unite.

DESIGN

Multicentre, pragmatic, open-label, parallel two-arm randomised controlled trial with an economic evaluation and a nested qualitative study.

SETTING

Orthopaedic departments of 31 hospitals in England and Wales recruited from July 2013, with final follow-up in September 2017.

PARTICIPANTS

Adults (aged ≥ 16 years) presenting within 2 weeks of injury with a clear, bicortical fracture of the scaphoid waist on plain radiographs.

INTERVENTIONS

Early surgical fixation using Conformité Européenne-marked headless compression screws. Below-elbow cast immobilisation for 6-10 weeks and urgent fixation of confirmed non-union.

MAIN OUTCOME MEASURES

The primary outcome and end point was the Patient-Rated Wrist Evaluation total score at 52 weeks, with a clinically relevant difference of 6 points. Secondary outcomes included Patient-Rated Wrist Evaluation pain and function subscales, Short Form questionnaire 12-items, bone union, range of movement, grip strength, complications and return to work.

RESULTS

The mean age of 439 participants was 33 years; 363 participants were male (83%) and 269 participants had an undisplaced fracture (61%). The primary analysis was on 408 participants with valid Patient-Rated Wrist Evaluation outcome data for at least one post-randomisation time point (surgery, n = 203 of 219; cast, n = 205 of 220). There was no clinically relevant difference in the Patient-Rated Wrist Evaluation total score at 52 weeks: the mean score in the cast group was 14.0 (95% confidence interval 11.3 to 16.6) and in the surgery group was 11.9 (95% confidence interval 9.2 to 14.5), with an adjusted mean difference of -2.1 in favour of surgery (95% confidence interval -5.8 to 1.6; p = 0.27). The non-union rate was low (surgery group, n = 1; cast group, n = 4). Eight participants in the surgery group had a total of 11 reoperations and one participant in the cast group required a reoperation for non-union. The base-case economic analysis at 52 weeks found that surgery cost £1295 per patient more (95% confidence interval £1084 to £1504) than cast treatment. The base-case analysis of a lifetime-extrapolated model confirmed that the cast treatment pathway was more cost-effective. The nested qualitative study identified patients' desire to have a 'sense of recovering', which surgeons should address at the outset.

LIMITATION

There were 17 participants who had initial cast treatment and surgery for confirmed non-union, which in 14 cases was within 6 months from randomisation and in three cases was after 6 months. Three of the four participants in the cast group who had a non-union at 52 weeks were not offered surgery.

CONCLUSIONS

Adult patients with an undisplaced or minimally displaced scaphoid waist fracture should have cast immobilisation and suspected non-unions immediately confirmed and urgently fixed. Patients should be followed up at 5 years to investigate the effect of partial union, degenerative arthritis, malunion and screw problems on their quality of life.

Perspectives on an Acceptance and Commitment Therapy (ACT) based program for patients with inflammatory bowel disease and comorbid anxiety and/or depressive symptoms

Background and aim: Individuals with inflammatory bowel disease (IBD) suffer higher rates of anxiety and depression than the general population, however, few psychological interventions are designed for this population. Acceptance and Commitment Therapy (ACT), aimed to increase psychological flexibility, may be useful to address the unique concerns of IBD sufferers. This study aimed to explore stakeholder perspectives on an ACT-based intervention prototype tailored to people with IBD and comorbid anxiety and/or depressive symptoms.Methods: An Intervention Mapping methodology guided intervention design. A qualitative exploratory design was used to investigate the perspectives of stakeholders. Focus groups or interviews obtained feedback from IBD patients of a major regional hospital, and health providers to IBD patients Australia-wide.Results: Findings were analysed using template analysis. Data saturation was reached at 19 participants (11 patients and 8 health professionals). Participants' perspectives on the ACT-based intervention were distributed across four themes: (1) Barriers to access and participation; (2) Timing in the illness trajectory; (3) ACT is useful for IBD; and (4) The more support, the better.Conclusion: The findings suggest that an ACT modality and blended delivery design is well received by patients and health professionals, providing recommendations to future researchers and clinicians on intervention design.

A Person-Centered Prehabilitation Program Based on Cognitive-Behavioral Physical Therapy for Patients Scheduled for Lumbar Fusion Surgery: A Randomized Controlled Trial

BACKGROUND

Prehabilitation programs have led to improved postoperative outcomes in several surgical contexts, but there are presently no guidelines for the prehabilitation phase before lumbar fusion surgery.

OBJECTIVE

The objective was to investigate whether a person-centered physical therapy prehabilitation program, based on a cognitive-behavioral approach, is more effective than conventional care in reducing disability and improving functioning after lumbar fusion surgery in patients with degenerative disk disease.

DESIGN

This study was a randomized controlled trial.

SETTING

The study took place at 2 private spine clinics and 1 university hospital.

PATIENTS

We prospectively enrolled 118 patients scheduled for lumbar fusion surgery.

INTERVENTION

The active intervention used a person-centered perspective and focused on promoting physical activity and targeting psychological risk factors before surgery. The control group received conventional preoperative care.

MEASUREMENTS

The primary outcome was the Oswestry Disability Index score. Secondary outcomes were back and leg pain intensity, catastrophizing, kinesiophobia, self-efficacy, anxiety, depression, health-related quality of life, and patient-specific functioning, physical activity, and physical capacity. Data were collected on 6 occasions up to 6 months postoperatively. A linear mixed model was used to analyze the change scores of each outcome.

RESULTS

No statistically significant between-group difference was found on the primary outcome (disability) over time (baseline to 6 months). Among secondary outcome measures, a statistically significant interaction effect ("Group × Time") was seen for the European Quality of Life 5 Dimensions Questionnaire. The largest between-group difference on the European Quality of Life 5 Dimensions Questionnaire index was seen 1 week prior to surgery and favored the active intervention. The largest between-group effect sizes at the 6-month follow-up favored the active intervention, and were seen for physical activity intensity, steps per day, and the One Leg Stand Test. Both groups reached the minimal important change for the primary outcome and, in several secondary outcomes (pain intensity, back and leg; pain catastrophizing; anxiety; health-related quality of life [EQ5D VAS]), already at 8-week follow-up.

LIMITATIONS

The participants' preoperative level of disability was lower than normative values, which suggests selection bias.

CONCLUSIONS

Both interventions led to clinically important changes, but it is not clear what kind of prehabilitation program is the most effective.
