Quality indicators for dementia and older people nearing the end of life: A systematic review

BACKGROUND

Robust quality indicators (QIs) are essential for monitoring and improving the quality of care and learning from good practice. We aimed to identify and assess QIs for the care of older people and people with dementia who are nearing the end of life and recommend QIs for use with routinely collected electronic data across care settings.

METHODS

A systematic review was conducted, including five databases and reference chaining. Studies describing the development of QIs for care of older people and those with dementia nearing the end of life were included. QIs were categorized as relating to processes or outcomes, and mapped against six care domains. The psychometric properties (acceptability, evidence base, definition, feasibility, reliability, and validity) of each QI were assessed; QIs were categorized as robust, moderate, or poor.

RESULTS

From 12,980 titles and abstracts screened, 37 papers and 976 QIs were included. Process and outcome QIs accounted for 780 (79.7%) and 196 (20.3%) of all QIs, respectively. Many of the QIs concerned physical aspects of care (n = 492, 50.4%), and very few concerned spiritual and cultural aspects of care (n = 19, 1.9%). Three hundred and fifteen (32.3%) QIs were robust and of those 220 were measurable using routinely collected electronic data. The final shortlist of 71 QIs came from seven studies.

CONCLUSIONS

Of the numerous QIs developed for care of older adults and those with dementia nearing the end of life, most had poor or moderate psychometric properties or were not designed for use with routinely collected electronic datasets. Infrastructure for data availability, combined with use of robust QIs, is important for enhancing understanding of care provided to this population, identifying unmet needs, and improving service provision.

Effectiveness of Menghini-Type Needles for Endoscopic Ultrasound-Guided Fine-Needle Aspiration of Pancreatic Masses

BACKGROUND

Cutting needles are thought to be effective as biopsy needles. A few types of cutting needles are available for endoscopic ultrasound-guided fine-needle aspiration (EUS-FNA), and the Menghini-type needle is an end-type cutting needle.

AIMS

A prospective randomized controlled trial was conducted to compare the results of EUS-FNA using a Menghini-type needle (needle M) versus a conventional needle (needle S).

METHODS

The main eligibility criteria were as follows: patients with a pancreatic mass referred for EUS-FNA, ≥ 20 years old, and a performance status < 4. The primary outcome was the sample quality. The secondary outcomes were factors associated with the sample quality, diagnostic accuracy, and adverse events.

RESULTS

A total of 97 patients were enrolled in this study. The sample quality for total puncture with needle M (92.8%) was significantly higher than that with needle S (81.4%) (p = 0.0305). The tumor size (p = 0.033) and type of needle (p = 0.031) were significant factors associated with adequate tissue collection in univariate and multivariate analyses (odds ratio [OR] 2.71; 95% confidence interval [CI] 1.12-6.54; p = 0.027 for tumor size, and OR 2.93; 95% CI 1.23-8.21; p = 0.0153 for type of needle). The diagnostic accuracy of each needle was 88.7% (86/97) with needle M and 73.2% (71/97) with needle S. Adverse events occurred in 2 of the 97 patients (0.02%).

CONCLUSION

A Menghini-type needle was able to obtain core tissue for histology more effectively than a conventional aspiration needle.

Women's Health Initiative Strong and Healthy Pragmatic Physical Activity Intervention Trial for Cardiovascular Disease Prevention: Design and Baseline Characteristics

BACKGROUND

National guidelines promote physical activity to prevent cardiovascular disease (CVD), yet no randomized controlled trial has tested whether physical activity reduces CVD.

METHODS

The Women's Health Initiative (WHI) Strong and Healthy (WHISH) pragmatic trial used a randomized consent design to assign women for whom cardiovascular outcomes were available through WHI data collection (N = 18 985) or linkage to the Centers for Medicare and Medicaid Services (N30 346), to a physical activity intervention or "usual activity" comparison, stratified by ages 68-99 years (in tertiles), U.S. geographic region, and outcomes data source. Women assigned to the intervention could "opt out" after receiving initial physical activity materials. Intervention materials applied evidence-based behavioral science principles to promote current national recommendations for older Americans. The intervention was adapted to participant input regarding preferences, resources, barriers, and motivational drivers and was targeted for 3 categories of women at lower, middle, or higher levels of self-reported physical functioning and physical activity. Physical activity was assessed in both arms through annual questionnaires. The primary outcome is major cardiovascular events, specifically myocardial infarction, stroke, or CVD death; primary safety outcomes are hip fracture and non-CVD death. The trial is monitored annually by an independent Data Safety and Monitoring Board. Final analyses will be based on intention to treat in all randomized participants, regardless of intervention engagement.

RESULTS

The 49 331 randomized participants had a mean baseline age of 79.7 years; 84.3% were White, 9.2% Black, 3.3% Hispanic, 1.9% Asian/Pacific Islander, 0.3% Native American, and 1% were of unknown race/ethnicity. The mean baseline RAND-36 physical function score was 71.6 (± 25.2 SD). There were no differences between Intervention (N = 24 657) and Control (N = 24 674) at baseline for age, race/ethnicity, current smoking (2.5%), use of blood pressure or lipid-lowering medications, body mass index, physical function, physical activity, or prior CVD (10.1%).

CONCLUSION

The WHISH trial is rigorously testing whether a physical activity intervention reduces major CV events in a large, diverse cohort of older women. Clinical Trials Registration Number: NCT02425345.

Towards a Core Outcome Set for Abdominal Aortic Aneurysm: Systematic Review of Outcomes Reported Following Intact and Ruptured Abdominal Aortic Aneurysm Repair

OBJECTIVE

To encompass the needs of all stakeholders and allow effective data synthesis from trials, registries, and other studies; a core outcome set for infrarenal abdominal aortic aneurysm (AAA) repair is needed. In this first stage, the aim was to report the range, frequency, and time of pre-specified outcomes reported following AAA repair.

DATA SOURCES

Medline, Embase, and CENTRAL databases 2010 - 2019 were searched using ProQuest Dialog™.

REVIEW METHODS

The systematic review was reported to Preferred Reporting Items for Systematic Reviews and Meta-Analysis guidelines (PRISMA), PROSPERO registration CRD42019130119. Outcomes were coded using Core Outcome Measures in Effectiveness Trials (COMET) taxonomy and presented separately for intact and rupture repairs, endovascular aneurysm repair (EVAR) and open repair, and time from repair (acute < 90 days vs. ≥ 1 year) (COMET Initiative 1582).

RESULTS

For intact AAA and rupture repair, a total of 231 and 70 reports with 589 255 and 177 465 patients respectively were included: only 98 and 19 respectively provided ≥ 1 year outcomes. Most studies were retrospective, with 13 randomised trials of intact AAA repair and five randomised trials of ruptured AAA repair. For intact AAA, the most common pre-specified COMET taxonomy outcomes were mortality (181), vascular complications (137), and re-intervention (52). EVAR studies dominated the vascular outcomes in acute and later time periods: excluding 47 reports from device registries, reduced vascular outcomes to 83. For ruptured AAA, the three most common outcomes were mortality (64), vascular (11), and hospital stay (10). The range of outcomes reported was wide with functioning outcomes reported from most randomised trials but few retrospective studies.

CONCLUSION

This review identifies the paucity of long term data and the disproportionate attention paid to vascular complications vs. patient functioning outcomes, this skew being accentuated by reporting from EVAR device registries. These data will inform focus groups, prior to a pan-European Delphi consensus, involving clinicians, patients, carers and providers, for developing core outcomes for repair of intact and ruptured AAA.

Benchmark performance of laparoscopic left lateral sectionectomy and right hepatectomy in expert centers

BACKGROUND & AIMS

Herein, we aimed to establish benchmark values - based on a composite indicator of healthcare quality - for the performance of laparoscopic left lateral sectionectomy (LLLS) and laparoscopic right hepatectomy (LRH) using data from expert centers.

METHODS

Data from a nationwide multicenter survey including all patients undergoing LLLS and LRH between 2000 and 2017 were analyzed. Textbook outcome (TO) completion was considered in patients fulfilling all 6 of the following characteristics: negative margins, no transfusion, no complication, no prolonged hospital stay, no readmission and no mortality. For each procedure, a cut-off laparoscopic liver resection (LLR) volume by center was associated with TO on multivariable analysis. These cut-offs defined the expert centers. The benchmark values were set at the 75th percentile of median outcomes among these expert centers.

RESULTS

Among 4,400 LLRs performed in 29 centers, 855 patients who underwent LLLS and 488 who underwent LRH were identified. The overall incidences of TO after LLLS and LRH were 43.7% and 23.8%, respectively. LLR volume cut-offs of 25 LLR/year (odds ratio [OR] 2.45; bootstrap 95% CI 1.65-3.69; p = 0.001) and 35 LLR/year (OR 2.55; bootstrap 95% CI 1.34-5.63; p = 0.003) were independently associated with completion of TO after LLLS and LRH, respectively. Eight centers for LLLS and 6 centers for LRH, including 516 and 346 patients undergoing LLLS/LRH respectively, reached these cut-offs and were identified as expert centers. After LLLS, benchmark values of severe complication, mortality and TO completion were defined as ≤5.3%, ≤1.2% and ≥46.6%, respectively. After LRH, benchmark values of severe complication, mortality and TO completion were ≤20.4%, ≤2.8% and ≥24.2%, respectively.

CONCLUSIONS

This study provides an up-to-date reference on the benchmark performance of LLLS and LRH in expert centers.

LAY SUMMARY

In a nationwide French survey of laparoscopic liver resection, expert centers were defined according to the completion of a textbook outcome, which is a composite indicator of healthcare quality. Benchmark values regarding intra-operative details and outcomes were established using data from 516 patients with laparoscopic left lateral sectionectiomy and 346 patients with laparoscopic right hepatectomy from expert centers. These values should be used as a reference point to improve the quality of laparoscopic resections.

Non-parametric recurrent events analysis with BART and an application to the hospital admissions of patients with diabetes

Much of survival analysis is concerned with absorbing events, i.e., subjects can only experience a single event such as mortality. This article is focused on non-absorbing or recurrent events, i.e., subjects are capable of experiencing multiple events. Recurrent events have been studied by many; however, most rely on the restrictive assumptions of linearity and proportionality. We propose a new method for analyzing recurrent events with Bayesian Additive Regression Trees (BART) avoiding such restrictive assumptions. We explore this new method via a motivating example of hospital admissions for diabetes patients and simulated data sets.

A Primer for the Use of Multilevel Models in Couple and Family Therapy Research

This article serves as a primer for understanding how to use multilevel modeling (MLM) techniques in couple and family therapy outcome and process research. It outlines the use of HLM and Mplus-two of many software programs that can perform multilevel modeling-and provides an applied example of using MLM to investigate the use of postsession feedback on couple satisfaction and change, as well as the influence of trauma on the use of postsession feedback. Two graduate students in COAMFTE accredited PhD programs read the primer and provided questions to the first author that arose. Answers to these questions have been incorporated throughout the explanation of this methodological approach in hopes of addressing common stuck points for those using MLM.

Improving Measurement in Couple and Family Therapy: An Item Response Theory Primer

The valid and reliable assessment of individual and relational functioning relies on high-quality assessment tools. Most assessments used in the field of couple and family therapy were developed using Classical Test Theory (CTT). An alternate theory for guiding the creation, evaluation, and scoring of assessments is Item Response Theory (IRT). IRT has several advantages over CTT and can be used to improve measurement in the field. For example, the IRT approach creates measures that are significantly more precise, yet uses fewer items, than scales created using CTT. This manuscript provides an overview of how IRT differs from CTT and describes the fundamental concepts and assumptions of IRT. Following this summary, we provide a step-by-step example of how IRT can be used to reduce the length of the Marital Disaffection Scale from 21 to 6 items without losing a significant amount of information about the construct.

Evaluation of machine learning methods to stroke outcome prediction using a nationwide disease registry

INTRODUCTION

Being able to predict functional outcomes after a stroke is highly desirable for clinicians. This allows clinicians to set reasonable goals with patients and relatives, and to reach shared after-care decisions for recovery or rehabilitation. The aim of this study was to apply various machine learning (ML) methods for 90-day stroke outcome predictions, using a nationwide disease registry.

METHODS

This study used the Taiwan Stroke Registry (TSR) which has prospectively collected data from stroke patients since 2006. Three known ML models (support vector machine, random forest, and artificial neural network), and a hybrid artificial neural network were implemented and evaluated by 10-time repeated hold-out with 10-fold cross-validation.

RESULTS

ML techniques present over 0.94 AUC in both ischemic and hemorrhagic stroke using preadmission and inpatient data. By adding follow-up data, the prediction ability improved to 0.97 AUC. We screened 206 clinical variables to identify 17 important features from the ischemic stroke dataset and 22 features from the hemorrhagic stroke dataset without losing much performance. Error analysis revealed that most prediction errors come from more severe stroke patients.

CONCLUSION

The study showed that ML techniques trained from large, cross-reginal registry datasets were able to predict functional outcome after stroke with high accuracy. The follow-up data is important which can further improve the predictive models' performance. With similar performances among different ML techniques, the algorithm's characteristics and performance on severe stroke patients will be the primary focus when we further develop inference models and artificial intelligence tools for potential medical.

Combination of variations in inflammation- and endoplasmic reticulum-associated genes as putative biomarker for bevacizumab response in KRAS wild-type colorectal cancer

Chemotherapy combined with the angiogenesis inhibitor bevacizumab (BVZ) is approved as a first-line treatment in metastatic colorectal cancer (mCRC). Limited clinical benefit underpins the need for improved understanding of resistance mechanisms and the elucidation of novel predictive biomarkers. We assessed germline single-nucleotide polymorphisms (SNPs) in 180 mCRC patients (Angiopredict [APD] cohort) treated with combined BVZ + chemotherapy and investigated previously reported predictive SNPs. We further employed a machine learning approach to identify novel associations. In the APD cohort IL8 rs4073 any A carriers, compared to TT carriers, were associated with worse progression-free survival (PFS) (HR = 1.51, 95% CI:1.03-2.22, p-value = 0.037) and TBK1 rs7486100 TT carriers, compared to any A carriers, were associated with worse PFS in KRAS wild-type (wt) patients (HR = 1.94, 95% CI:1.04-3.61, p-value = 0.037), replicating previous findings. Machine learning identified novel associations in genes encoding the inflammasome protein NLRP1 and the ER protein Sarcalumenin (SRL). A negative association between PFS and carriers of any A at NLRP1 rs12150220 and AA for SRL rs13334970 in APD KRAS wild-type patients (HR = 4.44, 95% CI:1.23-16.13, p-value = 0.005), which validated in two independent clinical cohorts involving BVZ, MAVERICC and TRIBE. Our findings highlight a key role for inflammation and ER signalling underpinning BVZ + chemotherapy responsiveness.

Primary healthcare planning, bottleneck analysis and performance improvement: An evaluation of processes and outcomes in a Nigerian context

Operational planning of interventions defines roadmaps, timelines and resources necessary for translating policies into expected health outcomes along the evidence-policy-implementation continuum. However, bottlenecks often hinder the attainment of objectives and the timely delivery of intervention packages leading to sub-optimal performance of health systems. Bottleneck identification, analysis and removal approaches to planning, which requires key stakeholders' participation, have been recommended to improve health system outcomes in LMICs. This study demonstrates how integration of participatory action research (PAR) within a quality improvement model can help navigate the complexities of health system bottleneck analyses, planning and performance improvement in a Nigerian sub-national context. The study is based on data collected between June 2016 and June 2017, from Chikun LGA in Kaduna State Nigeria. PAR was integrated into a quality improvement model called DIVA (Diagnose-Intervene-Verify-Adjust) applied across selected interventions (eMTCT, Antenatal care, skilled birth attendance, immunization and Integrated Management of Childhood Illnesses). PAR was used to identify and analyse health system bottlenecks, as well as develop, monitor implementation and follow-up on action plans to address them. Evaluations were conducted involving 2 cycles of DIVA. The outputs (bottleneck analysis charts, driver diagrams, operational plans, M/E reports, etc.) from each cycle of the DIVA process were collated and analysed. Bottlenecks identified include availability of human resources for health, availability of health commodities as well as geographical accessibility. These had implications on acceptability and quality of services. Mean Improvements recorded were 20.4%, 14.0% and 10.8% and 11.2%, 7.5%; 5.5% (across eMTCT, maternal health and child health interventions) in the 1 st and 2nd DIVA cycles respectively. This study highlights processes and outcomes of integrating PAR in quality improvement design and operations in health intervention programmes with a focus on health systems strengthening in a Nigerian context. Implementing the DIVA model using a PAR approach may be considered an effective strategy for planning and implementing health interventions in comparable settings.

Outcome measures for oncology alternative payment models: practical considerations and recommendations

OBJECTIVES

This paper aims to synthesize existing scholarship on quality measures in oncology, with a specific focus on outcome-based quality measures, which are often underutilized. We also present a set of "core outcome measures" that may be considered in future oncology alternative payment models (APMs).

STUDY DESIGN

Our research consists of a focused literature review, content analysis, and quality measure synthesis and categorization.

METHODS

We conducted a focused literature review to generate key evidence on quality measures in oncology. We studied 7 oncology quality assessment frameworks, encompassing 142 quality metrics, and synthesized recommendations using the Center for Medicare and Medicaid Innovation APM toolkit, focusing on outcome measures.

RESULTS

We present 34 outcome-based oncology quality measures for consideration, which are classified into 5 domains: clinical care (eg, hospital and emergency department visits, treatment effectiveness, mortality), safety (eg, infections, hospital adverse events), care coordination (for hospital and hospice care), patient and caregiver experience, and population health and prevention. Both general and indication-specific outcome measures should be considered in oncology APMs, as appropriate. Utilizing outcome-based measures will require addressing multiple challenges, ranging from risk adjustment to data quality assurance.

CONCLUSIONS

Oncology care will benefit from a more rigorous approach to quality assessment. The success of oncology APMs will require a robust set of quality measures that are relevant to patients, providers, and payers.

Improving Patient Experience in Hospital Settings: Assessing the Role of Toolkits and Action Research Through a Process Evaluation of a Complex Intervention

This article presents a process evaluation of the implementation and refinement of a patient experience toolkit (PET) by action researchers in six hospital wards in the English National Health Service (NHS). An initial assumption that health care professionals (HCPs) would use PET to improve patient experience proved unrealistic due to staff and service pressures. However, the action researchers' facilitation of PET and their support during the implementation of quality improvement efforts filled in for HCPs' lack of time. The findings suggest that the PET can be a successful guide for skilled facilitators working with HCPs, although excessive staff pressures should be avoided. Toolkits designed for implementation by HCPs should, therefore, be used sparingly; a more appropriate target audience may be facilitators. Furthermore, while the potential of action research is confirmed by this evaluation, HCPs' time to engage in service improvement is found to moderate the success of this increasingly prominent methodology.

Psychometric Evaluation of the Nursing Outcome Knowledge: Pain Management in People with Chronic Pain

Pain has a major impact on health and quality of life. Since the level of knowledge of painful conditions can influence how these are addressed and managed, assessing this knowledge in patients becomes crucial. As a result, it is necessary to have culturally adapted and validated instruments that specifically measure patients' knowledge of chronic pain management. The objective of this study was to carry out the Spanish cultural adaptation and the validation of the outcome Knowledge: Pain Management of the Nursing Outcomes Classification (NOC) in patients with chronic pain, defined as extent of understanding conveyed about causes, symptoms, and treatment of pain. A three-stage study was designed: 1) translation and cultural adaptation through an expert panel, 2) content validation, 3) clinical validation. This study provides nurses with a Spanish version of this scale adapted to their context, as well as a set of structured indicators to measure patients' knowledge about chronic pain. The results indicated that the culturally adapted Spanish version of the outcome Knowledge: Pain Management had a high level of content validity (CVI = 0.92), with 27 indicators being distributed between two factors. This version has been shown to be reliable in terms of inter-observer agreement (κ = 0.79) and internal consistency (α = 0.95). In conclusion, Knowledge: Pain Management has been shown to be reliable and valid to measure knowledge of chronic pain.

The Role of Pharmacy Refill Measures in Assessing Adherence and Predicting HIV Disease Markers in Youth with Perinatally-Acquired HIV (PHIV)

Antiretroviral (ARV) adherence is critical in monitoring disease response in youth with perinatally-acquired HIV (PHIV). We used pharmacy refill (PR) information for PHIV youth from the PHACS Memory Sub-study to calculate medication availability over 2, 4, and 6 months. PR, a proxy of adherence, was compared with self-reported 7-day adherence in predicting suppressed viral load (SVL < 400 copies/mL) and higher CD4% (≥ 25%). Among 159 PHIV youth, 79% were adherent by 7-day recall, and 62, 55, and 48% by PR over 2, 4, and 6 months, respectively. Agreement between 7-day recall and PR adherence was weak (Kappa = 0.09-0.25). In adjusted logistic regression models, adherence showed associations with SVL for 7-day recall (OR 2.78, 95% CI 1.08, 7.15) and all PR coverage periods (6-month: OR 3.24, 95% CI 1.22, 8.65). Similar associations were observed with higher CD4%. PR measures were predictive of study retention. Findings suggest a possibly independent role of PR adherence measures.

The Corrective Approach: Policy Implications of Recent Developments in QALY Measurement Based on Prospect Theory

BACKGROUND AND OBJECTIVES

Common health state valuation methodology, such as time tradeoff (TTO) and standard gamble (SG), is typically applied under several descriptively invalid assumptions, for example, related to linear quality-adjusted life years (QALYs) or expected utility (EU) theory. Hence, the current use of results from health state valuation exercises may lead to biased QALY weights, which may in turn affect decisions based on economic evaluations using such weights. Methods have been proposed to correct responses for the biases associated with different health state valuation techniques. In this article we outline the relevance of prospect theory (PT), which has become the dominant descriptive alternative to EU, for health state valuations and economic evaluations.

METHODS AND RESULTS

We provide an overview of work in this field, which aims to remove biases from QALY weights. We label this "the corrective approach." By quantifying PT parameters, such as loss aversion, probability weighting, and nonlinear utility, it may be possible to correct TTO and SG responses for biases in an attempt to produce more valid estimates of preferences for health states. Through straightforward examples, this article illustrates the effects of this corrective approach and discusses several unresolved issues that currently limit the relevance of corrected weights for policy.

CONCLUSIONS

Suggestions for research addressing these issues are provided. Nonetheless, if validly corrected health state valuations become available, we argue in favor of using these in economic evaluations.

To HTA or Not to HTA: Identifying the Factors Influencing the Rapid Review Outcome in Ireland

OBJECTIVES

Reimbursement systems are evolving and endeavor to balance access and affordability. One such evolution in Ireland is the compulsory rapid review (RR) process, the outcome from which is a recommendation for a health technology assessment (HTA) or no HTA. For drugs that avoid an HTA, evaluation times are shorter, lengthy price negotiations are avoided, and access is faster. In the absence of formal decision-making criteria around the requirement of an HTA, this study examines the factors influencing the outcome of the RR process in Ireland.

METHODS

A database was developed combining data from publicly available sources for drug evaluations conducted by the National Centre for PharmacoEconomics (NCPE) (January 2010-June 2017, n = 296). Because Irish cost data were not publicly available for all drugs, cost data from the Scottish Medicines Consortium were employed as a proxy. Employing logistic regressions, the factors influencing the RR outcome are revealed.

RESULTS

After an RR, an HTA was recommended for 55% of drugs. The regression results revealed therapeutic area (endocrine, musculoskeletal, and neoplasm), first-in-class and orphan disease increased the probability of an HTA. Furthermore, when proxy costs were included, results revealed that every €1000 increase in annual drug costs per patient increased the probability of an HTA being required by 1% and that an HTA was more likely than no HTA when annual drug costs exceeded €15 000.

CONCLUSION

Given the current focus on access and affordability, this study identifies the factors influencing the requirement of an HTA in Ireland.

Timeliness of Breast Cancer Treatment Within The Alaska Tribal Health System

PURPOSE

This study examined the time from breast cancer diagnosis to initiation of treatment among Alaska Native (AN) women. We evaluated the impact of age, cancer stage, and rural/urban residence at diagnosis.

METHODS

We evaluated characteristics of women recorded in the Alaska Native Tumor Registry who received a first diagnosis of breast cancer between 2009 and 2013. Median time from diagnosis to treatment was assessed. Associations of demographic and clinical characteristics with timely initiation of treatment were evaluated using logistic regression and Cox proportional hazards models.

RESULTS

Two hundred seventy-eight (278) AN women were diagnosed with invasive breast cancer in years 2009-2013. Mean age at diagnosis was 56.8 years (SD = 13.0). The median time from diagnosis to initiation of treatment was 23 days (P < .05) with most (94.6%, n = 263) meeting the ≤60-day guideline target. Time to treatment was not associated with rural/urban residence, age, or stage at cancer diagnosis.

CONCLUSION

These findings indicate that most AN women diagnosed with breast cancer within the AN Tribal Health System receive timely treatment after diagnosis.

Conducting and Reporting Case Series and Audits - Author Guidelines for Acupuncture in Medicine

This article aims to give guidance on the conduct and reporting of case series and audits of acupuncture, based on common problems that have arisen in the past. This type of project, and particularly the prospective case series or pre- post-intervention study, may give valuable evidence of the overall effectiveness of acupuncture for example in different situations and in different conditions and provides one step in the research pathway before generating an hypothesis. The project should be designed with the aim of reducing bias as much as possible. Careful and detailed planning is essential for the project to produce worthwhile results that readers can evaluate and replicate. Ethical issues should be considered and formal approval may be necessary. The patient group should be recruited systematically and baseline data obtained. The treatment given should be systematic and decisions to change or end treatment made explicit. The outcome should be measured in ways that are known to be reliable and valid. Musculoskeletal problems can be evaluated with scales for pain and confirmed by measuring one other symptom such as stiffness or one other aspect such as bothersomeness. Global change scores also provide supporting information, and the MYMOP (Measure Yourself Medical Outcome Profile) measure is popular when patients with different conditions are included. The design of questionnaires for beliefs and attitudes is a specialised area that should not be attempted without expert help. Adverse events should also be recorded. Analysis of the data and the best way of summarising and presenting the results are also discussed.

When Can I Trust The Robot? An Algorithm for CT-Based Robotic-Assisted Total Hip Arthroplasty

INTRODUCTION

Robotic-assisted total hip arthroplasty (THA) has been shown to demonstrate a variety of clinical benefits for patients, including reductions in dislocation rates, decreased impingement, and improved implant longevity. However, variability in surgeon experience with robotic systems can lead to inconsistent results. Mastery of the initial acetabular registration step is critical to performing a predictable and accurate robotic-assisted total hip replacement.

METHODS

We retrospectively reviewed 100 consecutive patients who underwent unilateral THA with MAKOplasty®. From this data, we reviewed where errors in planning or registration occurred. These cases either required a repeat registration if the error was caught early, or the errors were realized on postoperative imaging when the x-ray did not match the preoperative plan. Subsequently, we developed an algorithm to ensure accurate registration and implemented its use on the next 100 cases, again reviewing the intraoperative case data and postoperative x-rays for any errors.

RESULTS

Initial analysis revealed that 87 of the first 100 cases were correctly registered, where postoperative acetabular cup position matched the plan on first attempt. Of the remaining 13 cases that had a registration error, eight cases were identified intra-operatively and re-registered. There were five cases where the postoperative x-ray did not match the plan despite a "good" registration. For incorrectly registered cases (N = 13), seven of 13 were found to exhibit a type I error (initial registration), while six of 13 demonstrated a type II error (fine point registration). Following the implementation of our registration algorithm, we were able to decrease the discrepancy between the preoperative plan (planning) and the postoperative x-rays (execution) from 13% to 0% of cases.

CONCLUSION

In this study, we present a detailed method to examine registration errors during robotic-navigated THA with MAKOplasty®. From this analysis, we were able to develop a successful algorithm that allows the surgeon to ensure correct registration and ultimately a postoperative x-ray that matches the preoperative plan. Our algorithm presents a principled approach that provides the surgeon and patient confidence in the safety and efficacy a roboticassisted total hip replacement.

Use of an electronic patient-reported outcome measure in the management of patients with advanced chronic kidney disease: the RePROM pilot trial protocol

INTRODUCTION

Chronic kidney disease (CKD) affects up to 16% of adults in the UK. Patient quality of life is particularly reduced in end-stage renal disease and is strongly associated with increased hospitalisation and mortality. Thus, accurate and responsive healthcare is a key priority. Electronic patient-reported outcome measures (ePROMs) are online questionnaires which ask patients to self-rate their health status. Evidence in oncology suggests that the use of ePROM data within routine care, alongside clinical information, may enhance symptom management and improve patient outcomes. However, National Health Service (NHS)-based ePROM research in CKD is lacking. This pilot trial will assess the feasibility of undertaking a full-scale randomised controlled trial (RCT) in patients with CKD within the NHS.

METHODS AND ANALYSIS

The renal ePROM pilot trial is an investigator-led single-centre, open-label, two-arm randomised controlled pilot trial of 66 participants ≥18 years with advanced CKD. Participants will be randomised to receive either usual care or usual care supplemented with an ePROM intervention. Participants within the intervention arm will be asked to submit monthly self-reports of their health status using the ePROM system. The system will provide tailored information to patients in response to each report and notify the clinical team of patient deterioration. The renal clinical team will monitor for ePROM notifications and will respond with appropriate action, in line with standard clinical practice. Measures of study feasibility, participant quality of life and CKD severity will be completed at 3 monthly intervals. Health economic outcomes will be assessed. Clinicians will record treatment decision-making. Acceptability and feasibility of the protocol will be assessed alongside outcome measure and intervention compliance rates. Qualitative process evaluation will be conducted.

ETHICS AND DISSEMINATION

The findings will inform the design of a full-scale RCT and the results will be submitted for publication in peer-reviewed journals. The study has ethical approval.

Mixed-methods evaluation of the Perioperative Medicine Service for High-Risk Patients Implementation Pilot (POMSHIP): a study protocol

INTRODUCTION

Perioperative complications have a lasting effect on health-related quality of life and long-term survival. The Royal College of Anaesthetists has proposed the development of perioperative medicine (POM) services as an intervention aimed at improving postoperative outcome, by providing better coordinated care for high-risk patients. The Perioperative Medicine Service for High-risk Patients Implementation Pilot was developed to determine if a specialist POM service is able to reduce postoperative morbidity, failure to rescue, mortality and cost associated with hospital admission. The service involves individualised objective risk assessment, admission to a postoperative critical care unit and follow-up on the surgical ward by the POM team. This paper introduces the service and how it will be evaluated.

METHODS AND ANALYSIS OF THE EVALUATION

A mixed-methods evaluation is exploring the impact of the service. Clinical effectiveness of the service is being analysed using a 'before and after' comparison of the primary outcome (the PostOperative Morbidity Score). Secondary outcomes will include length of stay, validated surveys to explore quality of life (EQ-5D) and quality of recovery (Quality of Recovery-15 Score). The impact on costs is being analysed using 'before and after' data from the Patient-Level Information and Costing System and the National Schedule of Reference Costs. The perceptions and experiences of staff and patients with the service, and how it is being implemented, are being explored by a qualitative process evaluation.

ETHICS AND DISSEMINATION

The study was classified as a service evaluation. Participant information sheets and consent forms have been developed for the interviews and approvals required for the use of the validated surveys were obtained. The findings of the evaluation are being used formatively, to make changes in the service throughout implementation. The findings will also be used to inform the potential roll-out of the service to other sites.

Feasibility of Aerobic Exercise in the Subacute Phase of Recovery From Traumatic Brain Injury: A Case Series

BACKGROUND AND PURPOSE

Aerobic exercise is as important for individuals with traumatic brain injury (TBI) as for the general population; however, the approach to aerobic training may require some adaptation. The objective of the trial program was to examine the feasibility of introducing aerobic physical exercise programs into the subacute phase of multidisciplinary rehabilitation from moderate to severe TBI, which includes computerized cognitive training.

CASE DESCRIPTION

Five individuals undergoing inpatient rehabilitation with moderate or severe TBIs who also have concomitant physical injuries. All of these individuals were in the subacute phase of recovery from TBIs.

INTERVENTION

An 8-week progressive aerobic physical exercise program. Participants were monitored to ensure that they could both adhere to and tolerate the exercise program. In addition to the physical exercise, individuals were undergoing their standard rehabilitation procedures that included cognitive training. Neuropsychological testing was performed to gain an understanding of each individual's cognitive function.

OUTCOMES

Participants adhered to both aerobic exercise and cognitive training. Poor correlations were noted between heart rate reserve and ratings of perceived effort. Two minor adverse events were reported.

DISCUSSION

Despite concomitant physical injuries and cognitive impairments, progressive aerobic exercise programs seem feasible and well tolerated in subacute rehabilitation from moderate to severe TBI. Findings highlight the difficulty in measuring exercise intensity in this population.Video Abstract available for more insights from the authors (see Video, Supplemental Digital Content 1, available at: http://links.lww.com/JNPT/A235).

The Responsibility to Build Contexts That Enhance Human Functioning and Promote Valued Outcomes for People With Intellectual Disability: Strengthening System Responsiveness

This article describes a model that systems can use to build contexts that enhance human functioning and promote valued outcomes for individuals with intellectual disability (ID). Our premise is that that systems have a responsibility to build contexts that enhance human functioning and promote valued outcomes for people with ID, and that this obligation can be met through the use of contextual analysis to deliberately design and implement support strategies that are responsive to identified contextual factors. The model employs a 2-step process to identify context-based independent and intervening variables and align support strategies with identified context-based influencing factors, disability policy goals, and associated outcome domains. We propose a number of indicators that can be used to assess the quality of a system's responsiveness based on their implementation of the model. Implications for research and practice are discussed.

Establishing the diagnosis of multiple sclerosis in Croatian patients with clinically isolated syndrome: 2010 versus 2017 McDonald criteria

AIM

To compare the sensitivity, specificity and accuracy of the 2010 and 2017 revisions of the McDonald criteria in a Croatian cohort of patients with a clinically isolated syndrome (CIS).

METHODS

Prospectively collected data from 113 patients were retrospectively analyzed. Sensitivity, specificity and accuracy for both criteria were calculated regarding conversion to clinically definite multiple sclerosis (Poser CDMS) or multiple sclerosis (MS) (defined as fulfilment of clinical or MRI evidence for dissemination in space and the development of a second relapse and/or ≥1 new T2 lesions on the follow-up MRIs) during a two-year follow-up. Survival analysis was performed to estimate the cumulative risk of patients developing Poser CDMS. Binary logistic regression model was used to determine which variables are statistically significant predictors for the conversion to MS.

RESULTS

The 2017 revision had higher sensitivity (85 vs. 30% and 85 vs. 41%) and lower specificity (33 vs. 63% and 63 vs. 85%) compared to the 2010 revisions, for conversion to Poser CDMS and MS, respectively. Patients who did not meet the 2017 McDonald criteria had a higher chance of conversion-free survival for Poser CDMS than those who met the 2017 McDonald criteria (p = 0.037). Results of the multivariate regression analysis revealed that patients who at baseline fulfilled 2017 revisions of the McDonald criteria have the increased likelihood of conversion to MS (Exp(B) 9.68, 95%CI 3.62-25.90, p < 0.00001).

CONCLUSION

This study provides new information about the application of the 2017 revisions of the McDonald criteria in a Croatian cohort of patients with typical CIS.

Illuminating Graduate Medical Education Outcomes in Order to Improve Them

Optimizing clinician education is an essential step toward enhancing health outcomes, and graduate medical education (GME)-as the pipeline for producing the nation's physicians-is an appropriate target for improvement. This Invited Commentary focuses on the need to clarify the specific goals of GME and measure achievement of those goals, using consistent metrics. The authors report on an October 2017 National Academies of Sciences, Engineering, and Medicine (NASEM) workshop focused on this agenda. A broadly representative group of participants reflected strong consensus in support of using GME outcomes data to develop better approaches to education and related policy. Implementation challenges include identifying meaningful metrics, minimizing administrative burden, addressing privacy concerns, and recognizing variability in institutional mission and capabilities. The authors recommend creating a national inventory of current data sources and initiating a pilot program to collect and share common metrics, while advancing a national effort via a "neutral" convener, such as the NASEM. The authors assert that measuring and reporting GME outcomes is a professional responsibility that must now be tackled.

Developing Resident-Sensitive Quality Measures: A Model From Pediatric Emergency Medicine

PURPOSE

To begin closing the gap with respect to quality measures available for use among residents, the authors sought to identify and develop resident-sensitive quality measures (RSQMs) for use in the pediatric emergency department (PED) setting.

METHOD

In May 2016, the authors reviewed National Quality Measures Clearinghouse (NQMC) measures to identify resident-sensitive measures. To create additional measures focused on common, acute illnesses (acute asthma exacerbation, bronchiolitis, closed head injury [CHI]) in the PED, the authors used a nominal group technique (NGT) and Delphi process from September to December 2016. To achieve a local focus for developing these measures, all NGT and Delphi participants were from Cincinnati Children's Hospital Medical Center. Delphi participants rated measures developed through the NGT in two areas: importance of measure to quality care and likelihood that measure represents the work of a resident.

RESULTS

The review of NQMC measures identified 28 of 183 as being potentially resident sensitive. The NGT produced 67 measures for asthma, 46 for bronchiolitis, and 48 for CHI. These were used in the first round of the Delphi process. After two rounds, 18 measures for asthma, 21 for bronchiolitis, and 21 for CHI met automatic inclusion criteria. In round three, participants categorized the potential final measures by their top 10 and next 5.

CONCLUSIONS

This study describes a template for identifying and developing RSQMs that may promote high-quality care delivery during and following training. Next steps should include implementing and seeking validity evidence for the locally developed measures.

Development of Quality Indicators to Assess Oral Anticoagulant Management in Community Pharmacies for Patients with Atrial Fibrillation

BACKGROUND

Few studies have evaluated the quality of oral anticoagulant management by community pharmacists. There is no complete set of quality indicators available for this purpose.

OBJECTIVE

To develop a set of specific quality indicators to assess oral anticoagulant management by community pharmacists for patients with atrial fibrillation (AF).

METHODS

Quality indicators were developed in 3 phases. In phase 1, potential quality indicators were generated based on clinical guidelines and a literature review. In phase 2, a modified RAND appropriateness method involving 2 rounds was implemented with 9 experts, who judged the appropriateness of quality indicators generated in phase 1 based on the extent to which they were accurate, based on evidence, relevant, representative of best practices, and measurable in community pharmacies. Phase 3 consisted of a feasibility assessment in 5 community pharmacies on 2 patients each.

RESULTS

The final set included 38 quality indicators grouped into 6 categories: documentation (n = 29), risk assessment (n = 3), clinical control (n = 1), clinical follow-up (n = 15), choice of therapy (n = 11), and interaction management (n = 8). The quality indicators referred to process of care (n = 34), clinical outcomes (n = 2), or structure of care (n = 2). There were 24 quality indicators related to vitamin K antagonists (VKAs), and 17 were related to direct oral anticoagulants (DOACs). To assess quality indicators, a questionnaire was developed for completion by community pharmacists for each patient, which included 17 questions about VKA patients and 12 questions about DOAC patients.

CONCLUSIONS

A first set of quality indicators is now available to assess the quality of oral anticoagulant management by community pharmacists for patients with AF.

Psychological interventions for positive symptoms in schizophrenia: protocol for a network meta-analysis of randomised controlled trials

INTRODUCTION

There is rising awareness that we need multidisciplinary approaches integrating psychological treatments for schizophrenia, but a comprehensive evidence based on their relative efficacy is lacking. We will conduct a network meta-analysis (NMA), integrating direct and indirect comparisons from randomised controlled trials (RCTs) to rank psychological treatments for schizophrenia according to their efficacy, acceptability and tolerability.

METHODS AND ANALYSIS

We will include all RCTs comparing a psychological treatment aimed at positive symptoms of schizophrenia with another psychological intervention or with a no treatment condition (waiting-list and treatment as usual). We will include studies on adult patients with schizophrenia, excluding specific subpopulations (eg, first-episode patients or patients with psychiatric comorbidities). Primary outcome will be the change in positive symptoms on a published rating scale. Secondary outcomes will be acceptability (dropout), change in overall and negative symptoms of schizophrenia, response, relapse, adherence, depression, quality of life, functioning and adverse events. Published and unpublished studies will be sought through database searches, trial registries and websites. Study selection and data extraction will be conducted by at least two independent reviewers. We will conduct random-effects NMA to synthesise all evidences for each outcome and obtain a comprehensive ranking of all treatments. NMA will be conducted in Stata and R within a frequentist framework. The risk of bias in studies will be evaluated using the Cochrane Risk of Bias tool and the credibility of the evidence will be evaluated using an adaptation of the Grading of Recommendations Assessment, Development and Evaluation framework to NMA, recommended by the Cochrane guidance. Subgroup and sensitivity analyses will be conducted to assess the robustness of the findings.

ETHICS AND DISSEMINATION

No ethical issues are foreseen. Results from this study will be published in peer-reviewed journals and presented at relevant conferences.

Endovascular treatment for acute ischaemic stroke in routine clinical practice: prospective, observational cohort study (MR CLEAN Registry)

OBJECTIVE

To determine outcomes and safety of endovascular treatment for acute ischaemic stroke, due to proximal intracranial vessel occlusion in the anterior circulation, in routine clinical practice.

DESIGN

Ongoing, prospective, observational cohort study.

SETTING

16 centres that perform endovascular treatment in the Netherlands.

PARTICIPANTS

1488 patients included in the Multicentre Randomised Controlled Trial of Endovascular Treatment for Acute Ischaemic Stroke in the Netherlands (MR CLEAN) Registry who had received endovascular treatment, including stent retriever thrombectomy, aspiration, and all alternative methods for acute ischaemic stroke within 6.5 hours from onset of symptoms between March 2014 and June 2016.

MAIN OUTCOME MEASURES

The primary outcome was the modified Rankin Scale (mRS) score, ranging from 0 (no symptoms) to 6 (death) at 90 days after the onset of symptoms. Secondary outcomes were excellent functional outcome (mRS score 0-1), good functional outcome (mRS score 0-2), and favourable functional outcome (mRS score 0-3) at 90 days; score on the extended thrombolysis in cerebral infarction scale at the end of the intervention procedure; National Institutes of Health Stroke Scale score 24-48 hours after intervention; and complications that occurred during intervention, hospital admission, or three months' follow up period. Outcomes and safety variables in the MR CLEAN Registry were compared with the MR CLEAN trial intervention and control arms.

RESULTS

A statistically significant shift was observed towards better functional outcome in patients in the MR CLEAN Registry compared with the MR CLEAN trial intervention arm (adjusted common odds ratio 1.30, 95% confidence interval 1.02 to 1.67) and the MR CLEAN trial control arm (1.85, 1.46 to 2.34). The reperfusion rate, with successful reperfusion defined as a score of 2B-3 on the extended thrombolysis in cerebral infarction score, was 58.7%, the same as for patients in the MR CLEAN trial. Duration from onset of stroke to start of endovascular treatment and from onset of stroke to successful reperfusion or last contrast bolus was one hour shorter for patients in the MR CLEAN Registry. Symptomatic intracranial haemorrhage occurred in 5.8% of patients in the MR CLEAN Registry compared with 7.7% in the MR CLEAN trial intervention arm and 6.4% in the MR CLEAN trial control arm.

CONCLUSION

In routine clinical practice, endovascular treatment for patients with acute ischaemic stroke is at least as effective and safe as in the setting of a randomised controlled trial.

Mortality in a University Surgical Unit: What is an Avoidable Death?

Between January 1978 and December 1987 there were 23 557 surgical admissions to the University Surgical Unit in Southampton. During this period there were 543 deaths, an overall death per admission rate of 2.3%. During the 10-year period the number of admissions per year had risen from 1884 in 1978 (death per admission=3.6%) to 3467 in 1987 (death per admission rate=1.7%).

At the monthly audit meeting an attempt was made to classify each death as ‘avoidable’ or ‘unavoidable’. During this 10-year period it was considered that there were 89 ‘avoidable’ deaths. This represents an avoidable mortality rate (AMR) of 0.38%.

These ‘avoidable’ deaths were due to a wide variety of causes and this paper discusses the lessons learnt from a review of surgical mortality and outlines how units might compare results.

Development, implementation and first insights of a time- and location-independent longitudinal postgraduate curriculum in emergency medicine

Introduction, background and context: There have been few reports on the implementation of a structured curriculum for emergency medicine, as emergency medicine is not yet an established medical specialty for training in many European countries, including Switzerland and Germany. Because of the non-plannable workload in the emergency setting, common training approaches are often difficult to implement. Need-assessments of emergency medicine trainees commonly identify a need for interactive, time-independent ways of learning that integrate modern forms of knowledge transfer. Methods: In the present study, we assess the local needs of emergency medicine specialists and trainees for a curriculum in emergency medicine and elaborate possible solutions for the implementation of this curriculum, taking into account the special needs in a highly dynamic, unplannable environment, such as an interdisciplinary emergency department. Results: We describe the development of the emergency medicine curriculum on the basis of the six steps proposed by Kern for curriculum development in medical education, as well as the implementation, lessons learned and interval evaluation. Conclusions: The combination of multiple teaching formats, ranging from time- and location-independent solutions such as podcasted lectures to simulation-based training sessions, as well as small-group workshops and skill training sessions, might be a valuable approach to implementing a state-of-the-art curriculum in a busy emergency department.

Behavioral Health Integration into Primary Care: a Microsimulation of Financial Implications for Practices

BACKGROUND

New payments from Medicare encourage behavioral health services to be integrated into primary care practice activities.

OBJECTIVE

To evaluate the financial impact for primary care practices of integrating behavioral health services.

DESIGN

Microsimulation model.

PARTICIPANTS

We simulated patients and providers at federally qualified health centers (FQHCs), non-FQHCs in urban and rural high-poverty areas, and practices outside of high-poverty areas surveyed by the National Association of Community Health Centers, National Ambulatory Medical Care Survey, National Health and Nutrition Examination Survey, and National Health Interview Survey.

INTERVENTIONS

A collaborative care model (CoCM), involving telephone-based follow-up from a behaviorist care manager, or a primary care behaviorist model (PCBM), involving an in-clinic behaviorist.

MAIN MEASURES

Net revenue change per full-time physician.

KEY RESULTS

When behavioral health integration services were offered only to Medicare patients, net revenue was higher under CoCM (averaging $25,026 per MD in year 1 and $28,548/year in subsequent years) than PCBM (-$7052 in year 1 and -$3706/year in subsequent years). When behavioral health integration services were offered to all patients and were reimbursed by Medicare and private payers, only practices adopting the CoCM approach consistently gained net revenues. The outcomes of the model were sensitive to rates of patient referral acceptance, presentation, and therapy completion, but the CoCM approach remained consistently financially viable whereas PCBM would not be in the long-run across practice types.

CONCLUSIONS

New Medicare payments may offer financial viability for primary care practices to integrate behavioral health services, but this viability depends on the approach toward care integration.

[Do laymen understand information about hospital quality? An empirical verification using risk-adjusted mortality rates as an example]

INTRODUCTION

The effect of public reporting to improve quality in healthcare is reduced by the limited intelligibility of information about the quality of healthcare providers. This may result in worse health-related choices especially for older people and those with lower levels of education. There is, as yet, little information as to whether laymen understand the concepts behind quality comparisons and if this comprehension is correlated with hospital choices.

METHODS

An instrument with 20 items was developed to analyze the intelligibility of five technical terms which were used in German hospital report cards to explain risk-adjusted death rates. Two online presentations of risk-adjusted death rates for five hospitals in the style of hospital report cards were developed. An online survey of 353 volunteers tested the comprehension of the risk-adjusted mortality rates and included an experimental hospital choice.

RESULTS

The intelligibility of five technical terms was tested: risk-adjusted, actual and expected death rate, reference range and national average. The percentages of correct answers for the five technical terms were in the range of 75.0-60.2%. Between 23.8% and 5.1% of the respondents were not able to answer the question about the technical term itself. The least comprehensible technical terms were "risk-adjusted death rate" and "reference range". The intelligibility of the 20 items that were used to test the comprehension of the risk-adjusted mortality was between 89.5% and 14.2%. The two items that proved to be least comprehensible were related to the technical terms "risk-adjusted death rate" and "reference range". For all five technical terms it was found that a better comprehension correlated significantly with better hospital choices.

DISCUSSION

We found a better than average intelligibility for the technical terms "actual and expected death rate" and for "national average". The least understandable were "risk-adjusted death rate" and "reference range". Since the self-explanatory technical terms "actual and expected death rate" and "national average" are easy to understand and the comprehension is correlated with hospitals choices, we recommend using them for the presentation of measures which contain risk-adjusted mortality. The technical terms "risk-adjusted death rate" and "reference range" should stay in the background, since comprehension problems can be expected and explanations would have to be provided.

Patients' Preferences for Outcome, Process and Cost Attributes in Cancer Treatment: A Systematic Review of Discrete Choice Experiments

INTRODUCTION

As several studies have been conducted to elicit patients' preferences for cancer treatment, it is important to provide an overview and synthesis of these studies. This study aimed to systematically review discrete choice experiments (DCEs) about patients' preferences for cancer treatment and assessed the relative importance of outcome, process and cost attributes.

METHODS

A systematic literature review was conducted using PubMed and EMBASE to identify all DCEs investigating patients' preferences for cancer treatment between January 2010 and April 2016. Data were extracted using a predefined extraction sheet, and a reporting quality assessment was applied to all studies. Attributes were classified into outcome, process and cost attributes, and their relative importance was assessed.

RESULTS

A total of 28 DCEs were identified. More than half of the studies (56%) received an aggregate score lower than 4 on the PREFS (Purpose, Respondents, Explanation, Findings, Significance) 5-point scale. Most attributes were related to outcome (70%), followed by process (25%) and cost (5%). Outcome attributes were most often significant (81%), followed by process (73%) and cost (67%). The relative importance of outcome attributes was ranked highest in 82% of the cases where it was included, followed by cost (43%) and process (12%).

CONCLUSION

This systematic review suggests that attributes related to cancer treatment outcomes are the most important for patients. Process and cost attributes were less often included in studies but were still (but less) important to patients in most studies. Clinicians and decision makers should be aware that attribute importance might be influenced by level selection for that attribute.

Growing challenges for HIV programmes in Asia: clinic population trends, 2003-2013

The scale-up of antiretroviral therapy (ART) has led to a substantial change in the clinical population of HIV-positive patients receiving care. We describe the temporal trends in the demographic and clinical characteristics of HIV-positive patients initiating ART in 2003-13 within an Asian regional cohort. All HIV-positive adult patients that initiated ART between 2003 and 2013 were included. We summarized ART regimen use, age, CD4 cell count, HIV viral load, and HIV-related laboratory monitoring rates during follow-up by calendar year. A total of 16 962 patients were included in the analysis. Patients in active follow-up increased from 695 patients at four sites in 2003 to 11,137 patients at eight sites in 2013. The proportion of patients receiving their second or third ART regimen increased over time (5% in 2003 to 29% in 2013) along with patients aged ≥50 years (8% in 2003 to 18% in 2013). Concurrently, CD4 monitoring has remained stable in recent years, whereas HIV viral load monitoring, although varied among the sites, is increasing. There have been substantial changes in the clinical and demographic characteristics of HIV-positive patients receiving ART in Asia. HIV programmes will need to anticipate the clinical care needs for their aging populations, expanded viral load monitoring, and, the eventual increase in second and third ART regimens that will lead to higher costs and more complex drug procurement needs.

Investigating an approach to the alliance based on interpersonal defense theory

OBJECTIVE

Notwithstanding consistent findings of significant relationships between the alliance and outcome, questions remain to be answered about the relatively small magnitude of those correlations, the mechanisms underlying the association, and how to conceptualize the alliance construct. We conducted a preliminary study of an approach to the alliance based on interpersonal defense theory, which is an interpersonal reconceptualization of defense processes, to investigate the promise of this alternative approach as a way to address the outstanding issues.

METHOD

We employed qualitative, theory-building case study methodology, closely examining alliance processes at four time points in the treatment of a case in terms of a case formulation based on interpersonal defense theory.

RESULTS

The results suggested that our approach made it possible to recognize key processes in the alliance and that it helps explain how the alliance influences outcome. Our analyses also provided a rich set of concrete illustrations of the alliance phenomena identified by the theory.

CONCLUSIONS

The findings suggest that an approach to the alliance based on interpersonal defense theory holds promise. However, although the qualitative method we employed has advantages, it also has limitations. We offer suggestions about how future qualitative and quantitative investigations could build on this study.

Microvascular decompression for trigeminal neuralgia in patients with failed gamma knife surgery: Analysis of efficacy and safety

OBJECTIVE

Though it is usually successful, failure or delayed pain recurrence may occur after gamma knife surgery (GKS) in patients with trigeminal neuralgia (TN), and additional intervention may be required. This study aimed to investigate whether the safety and efficacy of microvascular decompression (MVD) were influenced by prior GKS.

PATIENTS AND METHODS

The authors retrospectively evaluated 36 consecutive TN patients who underwent MVD after failed GKS from January 2012 to June 2013. The clinical features, operative findings and surgical outcomes were reviewed and statistically analyzed, and the operation results were further compared with a cohort of 60 patients with no prior GKS.

RESULTS

At surgery, atrophy of the trigeminal nerve was observed in 13 patients (36.1%), arachnoid thickening in 6 patients (16.7%), adhesions between vessels and the trigeminal nerve in 8 patients (22.2%), and atherosclerotic plaque in the offending vessels in 3 patients (8.3%). The complete pain relief rates were 83.3% immediately after MVD and 72.2% at last follow-up, which showed no statistical difference when compared with patients without GKS. New or worsened facial numbness occurred in 7 patients (19.4%), which was significantly higher than those without GKS (p=0.02). Univariate analysis suggested that a positive pain response to the prior GKS correlated with better long-term outcome (p=0.015), and the existence of arachnoid adhesions correlated with higher risk of facial numbness (p=0.03).

CONCLUSIONS

MVD remains an appropriate and effective alternative therapy for patients with failed GKS, with no added technical difficulty. However, the risk of facial numbness seems to be higher than those with MVD alone.

Using Patient-Reported Outcome Measures (PROMs) to promote quality of care and safety in the management of patients with Advanced Chronic Kidney disease (PRO-trACK project): a mixed-methods project protocol

INTRODUCTION

Advanced chronic kidney disease (CKD) has a major effect on the quality of life and health status of patients and requires accurate and responsive management. The use of electronic patient-reported outcome measures (ePROMs) could assist patients with advanced pre-dialysis CKD, and the clinicians responsible for their care, by identifying important changes in symptom burden in real time. We report the protocol for 'Using Patient-Reported Outcome measures (PROMs) to promote quality of care and safety in the management of patients with Advanced Chronic Kidney Disease' (PRO-trACK) project, which will explore the feasibility and validity of an ePROM system for use in patients with advanced CKD.

METHODS AND ANALYSIS

The project will use a mixed-methods approach in three studies: (1) usability testing of the ePROM system involving up to 30 patients and focusing on acceptability and technical performance/stability; (2) ascertaining the views of patient and clinician stakeholders on the optimal use and administration of the CKD ePROM system-this will involve qualitative face-to-face/telephone interviewing with up to 30 patients or until saturation is achieved, focus groups with up to 15 clinical staff, management and IT team members; (3) psychometric assessment of the system, within a cohort of at least 180 patients with advanced CKD, to establish the measurement properties of the ePROM.

ETHICS AND DISSEMINATION

This project was approved by the West Midlands Edgbaston Research Ethics Committee (Reference 17/WM/0010) and received Health Research Authority (HRA) approval on 24 February 2017.The findings from this project will be provided to clinicians at the Department of Renal Medicine, Queen Elizabeth Hospitals, Birmingham (QEHB), NHS England, presented at conferences and to the Kidney Patients' Association, British Kidney Patient Association and the British Renal Society. Articles based on the findings will be written and submitted for publication in peer-reviewed journals.

Identifying mechanisms of change in a conversation therapy for aphasia using behaviour change theory and qualitative methods

BACKGROUND

Conversation therapy for aphasia is a complex intervention comprising multiple components and targeting multiple outcomes. UK Medical Research Council (MRC) guidelines published in 2008 recommend that in addition to measuring the outcomes of complex interventions, evaluation should seek to clarify how such outcomes are produced, including identifying the hypothesized mechanisms of change.

AIMS

To identify mechanisms of change within a conversation therapy for people with aphasia and their partners. Using qualitative methods, the study draws on behaviour change theory to understand how and why participants make changes in conversation during and after therapy.

METHODS & PROCEDURES

Data were derived from 16 participants (eight people with aphasia; eight conversation partners) who were recruited to the Better Conversations with Aphasia research project and took part in an eight session conversation therapy programme. The dataset consists of in-therapy discussions and post-therapy interviews, which are analysed using Framework Analysis.

OUTCOMES & RESULTS

Seven mechanisms of conversational behaviour change are identified and linked to theory. These show how therapy can activate changes to speakers' skills and motivation for using specific behaviours, and to the conversational opportunities available for strategy use.

CONCLUSIONS & IMPLICATIONS

These clinically relevant findings offer guidance about the processes involved in producing behavioural change via conversation therapy. A distinction is made between the process involved in motivating change and that involved in embedding change. Differences are also noted between the process engaged in reducing unhelpful behaviour and that supporting new uses of compensatory strategies. Findings are expected to have benefits for those seeking to replicate therapy's core processes both in clinical practice and in future research.

Vulnerable Emotional Expression In Emotion Focused Couples Therapy: Relating Interactional Processes To Outcome

This study examined whether interactions characterized by high expression of emotional vulnerability in one partner followed by a highly supportive response style by the other partner predicted greater improvement on domains of forgiveness, unfinished business, trust, and relationship satisfaction in a sample of 32 couples presenting for Emotion Focused Couples Therapy with unresolved emotional injuries. For each outcome measure, two separate hierarchical regression models were tested (injured partner vulnerability and offending partner supportiveness; offending partner vulnerability and injured partner supportiveness). Both models significantly predicted improvement on the majority of outcome measures. Practice suggestions for working with emotionally injured couples are provided in light of the findings.

Need for Outcome Scenario Analysis of Clinical Trials in Diabetes

Since the FDA requirement for cardiovascular safety of all new antihyperglycemic drugs to enter the market, the number and extent of phase 3 clinical trials has markedly increased. Unexpected trial results imply an enormous economic, personal and time cost and has deleterious effects over R&D. To prevent unforeseen developments in clinical trials, we recommend performing a comprehensive prospective outcome scenario analysis before launching the trial. In this commentary, we discuss the most important factors to take in consideration for prediction of clinical trial outcome scenarios and propose a theoretical model for decision making.
