Primary care identification and referral to improve safety of women experiencing domestic violence (IRIS): protocol for a pragmatic cluster randomised controlled trial

BACKGROUND

Domestic violence, which may be psychological, physical, sexual, financial or emotional, is a major public health problem due to the long-term health consequences for women who have experienced it and for their children who witness it. In populations of women attending general practice, the prevalence of physical or sexual abuse in the past year from a partner or ex-partner ranges from 6 to 23%, and lifetime prevalence from 21 to 55%. Domestic violence is particularly important in general practice because women have many contacts with primary care clinicians and because women experiencing abuse identify doctors and nurses as professionals from whom they would like to get support. Yet health professionals rarely ask about domestic violence and have little or no training in how to respond to disclosure of abuse.

METHODS/DESIGN

This protocol describes IRIS, a pragmatic cluster randomised controlled trial with the general practice as unit of randomisation. Our trial tests the effectiveness and cost-effectiveness of a training and support programme targeted at general practice teams. The primary outcome is referral of women to specialist domestic violence agencies. Forty-eight practices in two UK cities (Bristol and London) are randomly allocated, using minimisation, into intervention and control groups. The intervention, based on an adult learning model in an educational outreach framework, has been designed to address barriers to asking women about domestic violence and to encourage appropriate responses to disclosure and referral to specialist domestic violence agencies. Multidisciplinary training sessions are held with clinicians and administrative staff in each of the intervention practices, with periodic feedback of identification and referral data to practice teams. Intervention practices have a prompt to ask about abuse integrated in the electronic medical record system. Other components of the intervention include an IRIS champion in each practice and a direct referral pathway to a named domestic violence advocate.

DISCUSSION

This is the first European randomised controlled trial of an intervention to improve the health care response to domestic violence. The findings will have the potential to inform training and service provision.

Validation of an improved area-based method of calculating general practice-level deprivation

OBJECTIVE

To compare the methods of calculating practice deprivation scores in the absence of patient-level data.

STUDY DESIGN AND SETTING

Three methods of deriving general practice deprivation scores without patient-level data were compared against "gold standard" patient-level scores in 226 English practices. The three methods were lower super output area (LSOA), middle super output area (MSOA), and a geographical information systems (GIS) method. Working, if necessary, on the log scale, agreement between scores was assessed using Bland and Altman's method, Kappa statistics, and Pitman's test.

RESULTS

Based on the antilog 95% limits of agreement from Bland-Altman plots, GIS methods showed least variation compared with gold standard (0.66-1.47), followed by MSOA (0.61-1.70) and LSOA (0.38-2.29) methods. The differences in variances between both GIS and MSOA, and LSOA and MSOA comparisons, were greater than would be expected by chance (Pitman's P<0.001). High levels of agreement (kappa: 0.93, 0.86, and 0.80) were observed between GIS, MSOA, and LSOA methods compared with the "gold standard."

CONCLUSION

In situations where patient postcodes are unavailable, the GIS method is superior to area-based methods. However, where the GIS method cannot readily be applied, the MSOA method should be used in preference to the LSOA method.

Patient choice and evidence based decisions: The case of complementary therapies

OBJECTIVE

Current government policies simultaneously pursue the development of 'patient-led' and 'evidence-based' approaches to healthcare. The objective of this study was to explore how primary care clinicians and Primary Care Trust (PCT) managers balance these potentially competing tensions when considering popular, controversial treatments, like complementary therapies, in consultations (clinicians) or funding decisions (PCT managers).

SETTING AND PARTICIPANTS

We selected two case sites where complementary therapies were offered on NHS premises in England. We interviewed 18 PCT managers and clinicians, conducted an observation of a PCT meeting on complementary therapies and collected documentary data from referral databases and service funding bids. All interviews were taped, transcribed and analysed thematically. Interview, observation and documentary data were used to compare reported beliefs and behaviour to observed and documented behaviour.

RESULTS

The majority of clinicians and PCT managers claimed that research evidence guided their decisions; those who did not felt increasingly marginalized. However, discrepancies between reported and observed behaviour suggest that perceptions of research evidence, rather than fact based knowledge, predominated when considering complementary therapies.

CONCLUSION

In the case of NHS complementary therapy service provision, patient preference may be largely insignificant in clinician and PCT managerial decisions, with decisions based mainly on 'evidence rhetoric' devised from collectively agreed, unchallenged, tacit perceptions of research literature. If a patient-led NHS is to become a reality, NHS professionals need to cede the power that they wield with evidence rhetoric and acknowledge the legitimacy of patient preferences, views and alternative sources of evidence.

The risk of colorectal cancer with symptoms at different ages and between the sexes: a case-control study

BACKGROUND

Colorectal cancer is generally diagnosed following a symptomatic presentation to primary care. Although the presenting features of the cancer are well described, the risks they convey are less well known. This study aimed to quantify the risk of cancer for different symptoms, across age groups and in both sexes.

METHODS

This was a case-control study using pre-existing records in a large electronic primary care database. Cases were patients aged 30 years or older with a diagnosis of colorectal cancer between January 2001 and July 2006, matched to seven controls by age, sex and practice. All features of colorectal cancer recorded in the 2 years before diagnosis were identified. Features independently associated with cancer were identified using multivariable conditional logistic regression, and their risk of cancer quantified.

RESULTS

We identified 5477 cases, with 38,314 age, sex and practice-matched controls. Six symptoms and two abnormal investigations (anaemia and microcytosis) were independently associated with colorectal cancer. The positive predictive values of symptoms were: rectal bleeding, positive predictive value for a male aged > or = 80 years 4.5% (95% confidence interval 3.5, 5.9); change in bowel habit 3.9% (2.8, 5.5); weight loss 0.8% (0.5, 1.3); abdominal pain 1.2% (1.0, 1.4); diarrhoea 1.2% (1.0, 1.5) and constipation 0.7% (0.6, 0.8). Positive predictive values were lower in females and younger patients. Only 27% of patients had reported either of the two higher risk symptoms.

CONCLUSION

Most symptomatic colorectal cancers present with only a low-risk symptom. There is a need to find a method of identifying those at highest risk of cancer from the large number presenting with such symptoms.

Ambulatory care sensitive conditions: terminology and disease coding need to be more specific to aid policy makers and clinicians

OBJECTIVES

Ambulatory or primary care sensitive conditions (ACSCs) are those conditions for which hospital admission could be prevented by interventions in primary care. At present, different definitions of ACSCs are used for research and health policy analysis. This study aimed to explore the impact of different definitions of ACSCs and associated disease codes on analysis of health service activity.

STUDY DESIGN

Retrospective cross-sectional study using Hospital Episode Statistics (HES).

METHODS

All ACSCs identified by a literature search were documented. Conditions and codes were standardized using International Classification of Diseases (ICD) 10. A subset of ACSCs commonly used in England was compared with all 36 ACSCs identified by the search in a retrospective cross-sectional study using HES.

RESULTS

In total, 36 potential ACSCs were identified, which contained numerous subcategories. The most frequently used subset of ACSCs in the NHS only contains 19 ACSCs. There were 4,659,054 emergency admissions in England in 2005/6, of which 1,900,409 were ACSCs using the full set of 36 conditions. The proportion of these admissions attributable to the NHS subset of 19 ASCS was 35%. The underlying ICD10 codes used to define ACSCs vary widely across subsets of ACSCs used in the NHS. This impacts on rates of admission, length of stay and costs attributable to ACSCs.

CONCLUSIONS

Rates of hospital admission for ACSCs are increasingly used as a measure of the effectiveness of primary care. However, different conceptual interpretations of the term 'ACSC' and use of differing definitions and diagnostic codes impact on the proportion of admissions that are attributed as ACSCs. Some resolution of these inconsistencies is required for this measure to be more useful to decision makers.

"Medication career" or "moral career"? The two sides of managing antidepressants: a meta-ethnography of patients' experience of antidepressants

The UK National Institute for Clinical Excellence (NICE) Clinical Guidelines recommend routine prescription of antidepressants for moderate to severe depression. While many patients accept a prescription, one in three do not complete treatment. We carried out a meta-ethnography of published qualitative papers since 1990 whose focus is patients' experience of antidepressant use for depression, in order to understand barriers and facilitators to concordance and inform a larger qualitative study investigating antidepressant use over time. A systematic search of five databases was carried out, supported by hand searches of key journals, writing to first authors and examining reference lists. After piloting three critical appraisal tools, a modified version of the CASP (Critical Appraisal Skills Programme) checklist was used to appraise potentially relevant and qualitative papers. We carried out a synthesis using techniques of meta-ethnography involving translation and re-interpretation. Sixteen papers were included in the meta-ethnography. The papers fall into two related groups: (1) Papers whose focus is the decision-making relationship and the ways patients manage their use of antidepressants, and (2) Papers whose focus is antidepressants' effect on self-concept, ideas of stigma and its management. We found that patients' experience of antidepressants is characterised by the decision-making process and the meaning-making process, conceptualised here as the 'medication career' and 'moral career'. Our synthesis indicates ways in which general practitioners (GPs) can facilitate concordant relationships with patients regarding antidepressant use. First, GPs can enhance the potential for shared decision-making by reviewing patients' changing preferences for involvement in decision-making regularly throughout the patient's 'medication career'. Second, if GPs familiarise themselves with the competing demands that patients may experience at each decision-making juncture, they will be better placed to explore their patients' preferences and concerns--i.e. their 'moral career' of medication use. This may lead to valuable discussion of what taking antidepressants means for patients' sense of self and how their treatment decisions may be influenced by a felt sense of stigma.

Randomised controlled trial of Alexander technique lessons, exercise, and massage (ATEAM) for chronic and recurrent back pain: economic evaluation

OBJECTIVE

An economic evaluation of therapeutic massage, exercise, and lessons in the Alexander technique for treating persistent back pain.

DESIGN

Cost consequences study and cost effectiveness analysis at 12 month follow-up of a factorial randomised controlled trial.

PARTICIPANTS

579 patients with chronic or recurrent low back pain recruited from primary care.

INTERVENTIONS

Normal care (control), massage, and six or 24 lessons in the Alexander technique. Half of each group were randomised to a prescription for exercise from a doctor plus behavioural counselling from a nurse.

MAIN OUTCOME MEASURES

Costs to the NHS and to participants. Comparison of costs with Roland-Morris disability score (number of activities impaired by pain), days in pain, and quality adjusted life years (QALYs). Comparison of NHS costs with QALY gain, using incremental cost effectiveness ratios and cost effectiveness acceptability curves.

RESULTS

Intervention costs ranged from pound30 for exercise prescription to pound596 for 24 lessons in Alexander technique plus exercise. Cost of health services ranged from pound50 for 24 lessons in Alexander technique to pound124 for exercise. Incremental cost effectiveness analysis of single therapies showed that exercise offered best value ( pound61 per point on disability score, pound9 per additional pain-free day, pound2847 per QALY gain). For two-stage therapy, six lessons in Alexander technique combined with exercise was the best value (additional pound64 per point on disability score, pound43 per additional pain-free day, pound5332 per QALY gain).

CONCLUSIONS

An exercise prescription and six lessons in Alexander technique alone were both more than 85% likely to be cost effective at values above pound20 000 per QALY, but the Alexander technique performed better than exercise on the full range of outcomes. A combination of six lessons in Alexander technique lessons followed by exercise was the most effective and cost effective option.

Randomised controlled trial of Alexander technique lessons, exercise, and massage (ATEAM) for chronic and recurrent back pain

OBJECTIVE

To determine the effectiveness of lessons in the Alexander technique, massage therapy, and advice from a doctor to take exercise (exercise prescription) along with nurse delivered behavioural counselling for patients with chronic or recurrent back pain.

DESIGN

Factorial randomised trial. Setting 64 general practices in England.

PARTICIPANTS

579 patients with chronic or recurrent low back pain; 144 were randomised to normal care, 147 to massage, 144 to six Alexander technique lessons, and 144 to 24 Alexander technique lessons; half of each of these groups were randomised to exercise prescription.

INTERVENTIONS

Normal care (control), six sessions of massage, six or 24 lessons on the Alexander technique, and prescription for exercise from a doctor with nurse delivered behavioural counselling.

MAIN OUTCOME MEASURES

Roland Morris disability score (number of activities impaired by pain) and number of days in pain.

RESULTS

Exercise and lessons in the Alexander technique, but not massage, remained effective at one year (compared with control Roland disability score 8.1: massage -0.58, 95% confidence interval -1.94 to 0.77, six lessons -1.40, -2.77 to -0.03, 24 lessons -3.4, -4.76 to -2.03, and exercise -1.29, -2.25 to -0.34). Exercise after six lessons achieved 72% of the effect of 24 lessons alone (Roland disability score -2.98 and -4.14, respectively). Number of days with back pain in the past four weeks were lower after lessons (compared with control median 21 days: 24 lessons -18, six lessons -10, massage -7) and quality of life improved significantly. No significant harms were reported.

CONCLUSIONS

One to one lessons in the Alexander technique from registered teachers have long term benefits for patients with chronic back pain. Six lessons followed by exercise prescription were nearly as effective as 24 lessons.

Towards a better understanding of patients' perspectives of antibiotic resistance and MRSA: a qualitative study

BACKGROUND

Patients' expectations for antibiotics are known to influence prescribing, but little is known about patients' understanding of, and attitudes to, antibiotic resistance and whether these could modify treatment expectations.

OBJECTIVE

To explore primary care patients' perspectives on antibiotic resistance and methicillin-resistant Staphylococcus aureus (MRSA) and understand how these could modify expectations for antibiotics.

METHODS

A qualitative investigation using focus groups and semi-structured interviews with patients purposely sampled from low, intermediate and high antibiotic consumption groups from socio-economically contrasting general practices.

RESULTS

There was uncertainty concerning the nature and implications of antibiotic resistance for both individuals and the wider community. While some patients viewed antibiotic resistance as a problem for society, most did not see it as something that would affect them personally. Many thought that science would provide the solution through the development of new drugs. Responsibility for antibiotic resistance was mostly attributed to 'other' patients and GPs who had respectively overused and overprescribed antibiotics in the past. As MRSA was mainly seen as a hospital-based problem, blame was largely directed at hospital management and, to a lesser degree, doctors, nurses and cleaners. Concerns about antibiotic resistance were not regarded as a reason to modify individual use of antibiotics.

CONCLUSIONS

Many primary care patients are unaware of what antibiotic resistance is and how it arises. The causes of, and responsibility for, antibiotic resistance are usually attributed to external rather than personal factors and patients perceive that its solutions are outside of their control.

Designing a 'NHS friendly' complementary therapy service: a qualitative case study

BACKGROUND

Provision of complementary therapy services within the NHS is scarce and contested. However, their adoption may be more likely in a service model that is designed to the specifications of clinicians and Primary Care Trust (PCT) managers. Our objective was to identify the features of a 'NHS friendly' service to inform service designers who wish to develop NHS complementary therapy services.

METHODS

Using a case study approach, two sites offering complementary therapies on NHS premises were studied using interview and documentary data. We conducted interviews with 20 NHS professionals, including PCT managers and clinicians. We used descriptive content analysis to analyse interview data. We collected and analysed documentation, such as referral data, funding bids and evaluations, to compare reported and documented behaviour.

RESULTS

Ideally, a 'NHS friendly' complementary therapy service should offer a limited number of therapies for a specific condition for high priority patient populations (e.g. acupuncture for addictions). In this service model, the therapies should be perceived to have 'good' evidence for conditions where there are 'effectiveness gaps' (i.e. current treatments are limited). The service should be evaluated and regularly promoted. Inter-professional relationships would flourish through opportunities for informal contact and formal interactions, such as observations of consultations. However, the service should include gatekeeper mechanisms to control demand and avoid picking up 'unmet need' (i.e. individuals currently not accessing NHS services). The complementary therapy service should pay for itself and reduce NHS costs elsewhere, such as hospital admissions.

CONCLUSION

The service design model identified in this study is problematic. For example, it is contradictory to provide specific interventions for specific conditions within a holistic healthcare framework. It is difficult to avoid providing for 'unmet need' while concurrently filling 'effectiveness gaps'. In addition, demonstrating the impact of a community service on reducing hospital admissions is challenging. Those seeking to establish a NHS complementary therapy service might be well-advised to meet as many of the criteria of a 'NHS friendly' model as possible, recognising that its full realisation may be impossible. However, during periods of innovation and financial security, some relaxation of expectations may occur.

Predictors of complementary therapy use among asthma patients: results of a primary care survey

Patients with chronic conditions are increasingly using complementary therapies. Asthma is the most common chronic disease in the UK. Qualitative research has suggested reasons why asthma patients use complementary therapies. However, there is little reliable quantitative evidence regarding the prevalence of complementary therapy use among asthma patients and predictors of use. A postal survey of complementary therapy use among asthma patients was therefore conducted via 27 general practices across seven Primary Care Trusts within the South West Strategic Health Authority (England), during August 2005 to May 2006. A total of 14,833 asthma patients were identified. A 1-in-4 random sample generated 3693 potential respondents, of whom 1320 (36%) returned questionnaires. Taking full account of the survey design, 14.5% (190/1308; 95% confidence interval 12.5% to 16.6%) had used complementary therapies for asthma; 54% of these patients had not disclosed their complementary therapy use to a health professional. The three therapies most commonly used were homeopathy, herbal medicine and relaxation. Just over half of those using complementary therapies for asthma reported that they usually or always helped; the most common reported benefits were symptom reduction, calming breathing and reducing panic. Multivariable analyses indicated an inverted U-shaped relationship between complementary therapy use for asthma and age, and increased likelihood of use among women, those with educational qualifications, those not usually helped by asthma medication, and those who have difficulty sleeping because of asthma symptoms. Dissatisfaction with conventional care was not associated with complementary therapy use for asthma. Asthma patients may use complementary therapies with or without the knowledge of their healthcare providers. Open communication between professionals and patients about complementary therapies may be valuable to give patients enhanced opportunities to discuss the impact of asthma on their quality of life and the effectiveness of their conventional treatment.

The importance of anaemia in diagnosing colorectal cancer: a case-control study using electronic primary care records

Although anaemia is recognised as a feature of colorectal cancer, the precise risk is unknown. We performed a case–control study using electronic primary care records from the Health Improvement Network database, UK. A total of 6442 patients had a diagnosis of colorectal cancer, and were matched to 45 066 controls on age, sex, and practice. We calculated likelihood ratios and positive predictive values for colorectal cancer in both sexes across 1 g dl⁻¹ haemoglobin and 10-year age bands, and examined the features of iron deficiency.In men, 178 (5.2%) of 3421 cases and 47 (0.2%) of 23 928 controls had a haemoglobin <9.0 g dl⁻¹, giving a likelihood ratio (95% confidence interval) of 27 (19, 36). In women, the corresponding figures were 227 (7.5%) of 3021 cases and 58 (0.3%) of 21 138 controls, a likelihood ratio of 41 (30, 61). Positive predictive values increased with age and for each 1 g dl⁻¹ reduction in haemoglobin. The risk of cancer for current referral guidance was quantified. For men over 60 years with a haemoglobin <11 g dl⁻¹ and features of iron deficiency, the positive predictive value was 13.3% (9.7, 18) and for women with a haemoglobin <10 g dl⁻¹ and iron deficiency, the positive predictive value was 7.7% (5.7, 11). Current guidance for urgent investigation of anaemia misses some patients with a moderate risk of cancer, particularly men.

Explaining non-help-seeking amongst young adults with mental distress: a dynamic interpretive model of illness behaviour

Mental disorder is common amongst young adults and is associated with many adverse outcomes. Data, however, indicate that young adults are particularly unlikely to seek help for such distress. This paper describes a qualitative study of 23 young adults (aged 16 to 24 years) with mental distress. Interviewing was used to obtain detailed narratives of illness behaviour and to explore reasons for non-help-seeking. Help-seekers and non-help-seekers were interviewed. The findings allowed development of an explanatory model - the cycle of avoidance (COA) - which contributes towards attempts to provide a dynamic understanding of help-seeking behaviour. Dominant approaches tend to be deterministic and static and to account for non-help-seeking in terms of 'barriers' to care, which although easily translated into targets for policy intervention, are superficial representations of complex issues. The COA conceptualises help-seeking as a circular process and offers a model of 'non-help-seeking' in which lay conceptions of mental distress, the social meanings attached to 'help-seeking' and treatment, and the purposeful action of individuals, assume central importance. Although derived in the context of young adulthood and mental distress, this model may have wider applicability as a theoretical template for explaining non-help-seeking in other age groups and conditions, and other illness behaviours.

GPs' experiences of primary care mental health research: a qualitative study of the barriers to recruitment

OBJECTIVE

To investigate the perceived barriers among GPs towards introducing participation in randomized controlled trials (RCTs) to patients presenting with depression during consultations.

METHODS

Qualitative study using semi-structured interviews. Interviews were recorded using a digital voice recorder, transcribed verbatim and analysed using the Framework Approach. The participants were 41 GPs from five primary care trusts in the South West who were collaborating with the University of Bristol on an RCT recruiting patients with depression.

RESULTS

Three themes were identified: (i) concern about protecting the vulnerable patient and the impact on the doctor-patient relationship; (ii) the perceived lack of skill and confidence of GPs to introduce a request for research participation within a potentially sensitive consultation; and (iii) the priority given to clinical and administrative issues over research participation. These themes were underpinned by GPs' observations that consultations with people about depression differed in content, style and perceived difficulty compared to other types of consultations.

CONCLUSION

Depressed patients were often viewed as vulnerable and in need of protection and it was seen as difficult and intrusive to introduce research. Patients were not always given the choice to participate in research in the same way that they are encouraged to participate in treatment decision making. A lack of skills in introducing research could be addressed with training through the new Primary Care Research Network. A more radical change in clinician attitudes and policy may be needed in order to give research a higher priority within primary care.

Narrative accounts of hereditary risk: knowledge about family history, lay theories of disease, and "internal" and "external" causation

In this study, the authors sought to examine how risk information is articulated in relation to health problems that people identify as personally important and relevant. The respondents were receptive to health education messages, using different types of information in relation to its personal relevance and as a resource for managing and exercising control over perceived risk. People were not fatalistic about disease risk, as reported in previous research. Instead, they were responsive to complex public health messages and actively engaged in rationalizing their health risks, although this did not necessarily result in behavioral change. Consequently, a theoretical distinction exists between taking responsibility for evaluating complex public health messages and taking responsibility for behavioral change. The authors conclude that people's rationalizations about health risks often mirror the medical model of disease, suggesting that they are responsive to, and not fatalistic toward, such public health information.
