A meta-ethnography of patients' experiences of chronic pelvic pain : struggling to construct chronic pelvic pain as 'real'

AIM: To review systematically and integrate the findings of qualitative research to increase our understanding of patients' experiences of chronic pelvic pain. BACKGROUND: Chronic pelvic pain is a prevalent pain condition with a high disease burden for men and women. Its multifactorial nature makes it challenging for clinicians and patients. DESIGN: Synthesis of qualitative research using meta-ethnography. DATA SOURCES: Five electronic bibliographic databases from inception until March 2014 supplemented by citation tracking. Of 488 papers retrieved, 32 met the review aim. REVIEW METHODS: Central to meta-ethnography is identifying 'concepts' and developing a conceptual model through constant comparison. Concepts are the primary data of meta-ethnography. Two team members read each paper to identify and collaboratively describe the concepts. We next compared concepts across studies and organized them into categories with shared meaning. Finally, we developed a conceptual model, or line of argument, to explain the conceptual categories. RESULTS: Our findings incorporate the following categories into a conceptual model: relentless and overwhelming pain; threat to self; unpredictability, struggle to construct pain as normal or pathological; a culture of secrecy; validation by diagnosis; ambiguous experience of health care; elevation of experiential knowledge and embodiment of knowledge through a community. CONCLUSION: The innovation of our model is to demonstrate, for the first time, the central struggle to construct 'pathological' vs. 'normal' chronic pelvic pain, a struggle that is exacerbated by a culture of secrecy. More research is needed to explore men's experience and to compare this with women's experience

Recovery of muscle strength and power after limb-lengthening surgery

Barker KL, Lamb SE, Simpson HRW. Recovery or muscle strength and power after limb-lengthening surgery. Arch Phys Med Rehabil 2010;91:384-8. Objective: To report muscle strength, power, and function after limb-lengthening surgery performed by using the Ilizarov technique. Design: Prospective, longitudinal observational study of a cohort of consecutive patients who underwent limb-lengthening distraction followed up for 2 years after surgery. Setting: National Health Service hospital specializing in orthopedic surgery. Participants: Patients (N=16) who had undergone limb-lengthening surgery performed by using the Ilizarov method (11 men, 5 women; mean age=27y; range, 13-56y). Interventions: None. Main Outcome Measures: Muscle strength and power were assessed by using 2 validated measures: isokinetic concentric strength of the quadriceps and hamstrings measured by using a dynamometer and leg extensor power. Measures were recorded preoperatively and at 6, 12, and 24 months after the completion of lengthening. Function was measured by 2 timed tests of functional performance: stair climbing and sit-to-stand. Results: Overall results were good with high reports of function and satisfactory clinical examination. Both concentric muscle strength and leg power showed a clear pattern of decreased muscle strength at 6 months after frame removal, improving throughout the study period until it was within 3% of the preoperative value at 2 years. By 2 years, self-reported function and ability to complete timed functional tests had returned to or improved on the preoperative values. Muscle strength remained slightly below the preoperative value; this was more pronounced in the quadriceps than the hamstrings. There was no association between muscle strength and the amount of lengthening that had been undertaken. Conclusions: This study suggests that there is a small residual decrease in muscle strength and power after limb-lengthening surgery but that these do not adversely impact on a patients' ability to perform everyday functional activities

A Mechanism for the Age Gelation of UHT Concentrated Milk

Studies that systematically search for and synthesise qualitative research are becoming more evident in health care, and they can make an important contribution to patient care. Our team was funded to complete a meta-ethnography of patients’ experience of chronic musculoskeletal pain. It has been 25 years since Noblit and Hare published their core text on meta-ethnography, and the current health research environment brings additional challenges to researchers aiming to synthesise qualitative research. Noblit and Hare propose seven stages of meta-ethnography which take the researcher from formulating a research idea to expressing the findings. These stages are not discrete but form part of an iterative research process. We aimed to build on the methods of Noblit and Hare and explore the challenges of including a large number of qualitative studies into a qualitative systematic review. These challenges hinge upon epistemological and practical issues to be considered alongside expectations about what determines high quality research. This paper describes our method and explores these challenges. Central to our method was the process of collaborative interpretation of concepts and the decision to exclude original material where we could not decipher a concept. We use excerpts from our research team's reflexive statements to illustrate the development of our methods

Patients' experiences of chronic non-malignant musculoskeletal pain : a qualitative systematic review

Musculoskeletal (MSK) pain is one of the most predominant types of pain and accounts for a large portion of the primary care workload. AIM: To systematically review and integrate the findings of qualitative research to increase understanding of patients' experiences of chronic non-malignant MSK pain. DESIGN AND SETTING: Synthesis of qualitative research using meta-ethnography using six electronic databases up until February 2012 (Medline, Embase, Cinahl, Psychinfo, Amed and HMIC). METHOD: Databases were searched from their inception until February 2012, supplemented by hand-searching contents lists of specific journals for 2001-2011 and citation tracking. Full published reports of qualitative studies exploring adults' own experience of chronic non-malignant MSK pain were eligible for inclusion. RESULTS: Out of 24 992 titles, 676 abstracts, and 321 full texts were screened, 77 papers reporting 60 individual studies were included. A new concept of pain as an adversarial struggle emerged. This adversarial struggle was to: 1) affirm self; 2) reconstruct self in time; 3) construct an explanation for suffering; 4) negotiate the healthcare system; and 5) prove legitimacy. However, despite this struggle there is also a sense for some patients of 6) moving forward alongside pain. CONCLUSIONS: This review provides a theoretical underpinning for improving patient experience and facilitating a therapeutic collaborative partnership. A conceptual model is presented, which offers opportunities for improvement by involving patients, showing them their pain is understood, and forming the basis to help patients move forward alongside their pain

The MRC Spine Stabilization Trial: Surgical Methods, Outcomes, Costs, and Complications of Surgical Stabilization

STUDY DESIGN:A review of the surgical costs and results in a group of patients randomly allocated to surgery as part of a large prospective randomized trial of patients with chronic back pain.OBJECTIVE:To report the observational data from the surgical arm of a randomized trial comparing surgery with intensive rehabilitation for chronic low back pain. Clinical and economic data are reported.SUMMARY OF BACKGROUND DATA:Surgery for chronic low back pain is a well established but unproven intervention. The most cost-effective technique for spinal stabilization is still not established.METHODS:One hundred six patients with chronic low back pain were randomized to the surgical group of a randomized trial comparing spinal fusion of the lumbar with a 3 week intensive rehabilitation program. The primary outcomes were the Oswestry Disability Index (ODI) and the Shuttle Walking Test measured at baseline and 2 years postrandomization. Patients were stratified by preoperative diagnosis, smoking habit, and litigation. Complications were assessed and costs analyzed.RESULTS:Of the 176 surgical patients, 56 underwent postero-lateral fusion, 57 underwent interbody fusion, and 24 underwent flexible stabilization of the spine. The mean ODI for all patients in the surgical arm of the trial improved from a baseline of 46.5 (SD 14.6) to 34.2 (SD 21) at 2 years. Health care costs were higher ( 3109 pounds difference) for more complex procedures, and nearly 6 times as many early complications occurred with the more complex procedures. Smoking and unemployment were associated with worse results whereas litigation did not adversely affect the outcome.CONCLUSION:These observational changes in the ODI after surgery are similar to those reported from other studies of spinal fusion. More complex surgery is more expensive with more complications than postero-lateral fusion

Active treatment for idiopathic adolescent scoliosis (ACTIvATeS) : a feasibility study

BACKGROUND: The feasibility of conducting a definitive randomised controlled trial (RCT) evaluating the clinical effectiveness and cost-effectiveness of scoliosis-specific exercises (SSEs) for adolescent idiopathic scoliosis (AIS) is uncertain. OBJECTIVES: The aim of this study was to assess the feasibility of conducting a large, multicentre trial of SSE treatment for patients with AIS, in comparison with standard care, and to refine elements of the study design. The objectives were to (1) update a systematic review of controlled trials evaluating the efficacy of SSE in AIS; (2) survey UK orthopaedic surgeons and physiotherapists to determine current practice, patient populations and equipoise; (3) randomise 50 adolescents to a feasibility trial of either usual care or SSE interventions across a range of sites; (4) develop, document and assess acceptability and adherence of interventions; (5) assess and describe training requirements of physiotherapists; and (6) gain user input in all relevant stages of treatment and protocol design. DESIGN: Multicomponent feasibility study including UK clinician survey, systematic literature review and a randomised feasibility trial. SETTING: The randomised feasibility study involved four secondary care NHS trusts providing specialist care for patients with AIS. PARTICIPANTS: The randomised feasibility study recruited people aged 10-16 years with mild AIS (Cobb angle of < 50°). INTERVENTIONS: The randomised study allocated participants to standard practice of advice and education or a physiotherapy SSE programme supported by a home exercise plan. Our choice of intervention was informed by a systematic review of exercise interventions for AIS. MAIN OUTCOME MEASURES: The main outcome was feasibility of recruitment to the randomised study. Other elements were to inform choice of outcomes for a definitive trial and included curve severity, quality of life, requirement for surgery/brace, adverse events, psychological symptoms, costs and health utilities. RESULTS: A UK survey of orthopaedic consultants and physiotherapists indicated a wide variation in current provision of exercise therapy through physiotherapy services. It also found that clinicians from at least 15 centres would be willing to have their patients involved in a full study. A systematic review update found five new studies that were generally of low quality but showed some promise of effectiveness of SSE. The randomised study recruited 58 patients from four NHS trusts over 11 months and exceeded the pre-specified target recruitment rate of 1.4 participants per centre per month, with acceptable 6-month follow-up (currently 73%). Adherence to treatment was variable (56% of participants completed treatment offered). The qualitative study found the exercise programme to be highly acceptable. We learnt important lessons from patient and public involvement during the study in terms of study and intervention presentation, as well as practical elements such as scheduling of intervention sessions. CONCLUSIONS: A definitive RCT evaluating clinical effectiveness and cost-effectiveness of SSE for idiopathic scoliosis is warranted and feasible. Such a RCT is a priority for future work in the area. There is a sufficiently large patient base, combined with willingness to be randomised within specialist UK centres. Interventions developed during the feasibility study were acceptable to patients, families and physiotherapists and can be given within the affordability envelope of current levels of physiotherapy commissioning.
