"Any other comments?" Open questions on questionnaires - a bane or a bonus to research?

BACKGROUND: The habitual "any other comments" general open question at the end of structured questionnaires has the potential to increase response rates, elaborate responses to closed questions, and allow respondents to identify new issues not captured in the closed questions. However, we believe that many researchers have collected such data and failed to analyse or present it. DISCUSSION: General open questions at the end of structured questionnaires can present a problem because of their uncomfortable status of being strictly neither qualitative nor quantitative data, the consequent lack of clarity around how to analyse and report them, and the time and expertise needed to do so. We suggest that the value of these questions can be optimised if researchers start with a clear understanding of the type of data they wish to generate from such a question, and employ an appropriate strategy when designing the study. The intention can be to generate depth data or 'stories' from purposively defined groups of respondents for qualitative analysis, or to produce quantifiable data, representative of the population sampled, as a 'safety net' to identify issues which might complement the closed questions. SUMMARY: We encourage researchers to consider developing a more strategic use of general open questions at the end of structured questionnaires. This may optimise the quality of the data and the analysis, reduce dilemmas regarding whether and how to analyse such data, and result in a more ethical approach to making best use of the data which respondents kindly provide.

A randomised, controlled, triple-blind trial of the efficacy of homeopathic treatment for chronic fatigue syndrome.

OBJECTIVE: There is no management regime for chronic fatigue syndrome (CFS) that has been found to be universally beneficial and no treatment can be considered a "cure". Patients with CFS may use complementary and alternative medicine (CAM). Our aim was to evaluate homeopathic treatment in reducing subjective symptoms of CFS. METHOD: Using a triple-blind design (patient and homeopath blind to group assignment and data analyst blind to group until after initial analyses to reduce the possibility of bias due to data analyst), we randomly assigned patients to homeopathic medicine or identical placebo. One hundred and three patients meeting the Oxford criteria for CFS were recruited from two specialist hospital out patient departments. Patients had monthly consultations with a professional homeopath for 6 months. Main outcome measures were scores on the subscales of the Multidimensional Fatigue Inventory (MFI) and proportions of each group attaining clinically significant improvements on each subscale. Secondary outcome measures were the Fatigue Impact Scale (FIS) and the Functional Limitations Profile (FLP). Ninety-two patients completed treatment in the trial (47 homeopathic treatment, 45 placebo). Eighty-six patients returned fully or partially completed posttreatment outcome measures (41 homeopathic treatment group who completed treatment, 2 homeopathic treatment group who did not complete treatment, 38 placebo group who completed treatment, and 5 placebo group who did not complete treatment). RESULTS: Seventeen of 103 patients withdrew from treatment or were lost to follow-up. Patients in the homeopathic medicine group showed significantly more improvement on the MFI general fatigue subscale (one of the primary outcome measures) and the FLP physical subscale but not on other subscales. Although group differences were not statistically significant on four out of the five MFI subscales (the primary outcome measures), more people in the homeopathic medicine group showed clinically significant improvement. More people in the homeopathic medicine group showed clinical improvement on all primary outcomes (relative risk=2.75, P=.09). CONCLUSIONS: There is weak but equivocal evidence that the effects of homeopathic medicine are superior to placebo. Results also suggest that there may be nonspecific benefits from the homeopathic consultation. Further studies are needed to determine whether these differences hold in larger samples.

Nurses' views of using computerized decision support software in NHS Direct.

BACKGROUND: Nurses working in NHS Direct, the 24-hour telephone advice line in England, use computerized decision support software to recommend to callers the most appropriate service to contact, or to advise on self-care. AIMS: To explore nurses' views of their roles and the computerized decision support software in NHS Direct. METHODS: Qualitative analysis of semi-structured interviews with 24 NHS Direct nurses in 12 sites. FINDINGS: Nurses described both the software and themselves as essential to the clinical decision-making process. The software acted as safety net, provider of consistency, and provider of script, and was relied upon more when nurses did not have clinical knowledge relevant to the call. The nurse handled problems not covered by the software, probed patients for the appropriate information to enter into the software, and interpreted software recommendations in the light of contextual information which the software was unable to use. Nurses described a dual process of decision-making, with the nurse as active decision maker looking for consensus with the software recommendation and ready to override recommendations made by the software if necessary. However, nurses' accounts of the software as a guide, prompt or support did not fully acknowledge the power of the software, which they are required to use, and the recommendation of which they are required to follow under some management policies. Over time, the influence of nurse and software merges as nurses internalize the software script as their own knowledge, and navigate the software to produce recommendations that they feel are most appropriate. CONCLUSIONS: The nurse and the software have distinct roles in NHS Direct, although the effect of each on the clinical decision-making process may be difficult to determine in practice.

Evaluating decision aids--where next?

Decision aids have been developed to help patients become involved in decision-making about their individual health care. During the evaluation of a particular decision aid in maternity care--a set of 10 'Informed Choice' leaflets--we considered the lessons learnt for evaluation of decision aids in the future. Decision aids have been tested mainly in explanatory trials and have been found to be effective. We argue that existing decision aids should be subjected to more pragmatic trials to test their effectiveness in the real world. The small amount of evidence on their use in the real world shows that they face challenges, resulting in poor implementation. Therefore, we propose that implementation strategies are developed which take heed of the findings of research on getting evidence into practice, and in particular address structural barriers such as the lack of time available to health professionals. We recommend that these 'decision aid implementation packages' are developed in conjunction with both health professionals and patients, and identify and address potential barriers to both the delivery of patient involvement in decision-making, and the use of decision aids, in the real world. These 'packages' can then be submitted to pragmatic evaluation.

Complementary and alternative medicine use by patients with cancer in Wales: a cross sectional survey.

OBJECTIVES: To determine the prevalence and cost of complementary and alternative medicine (CAM) use, and examine perceived satisfaction and reasons for using CAM. DESIGN AND SETTING: Cross sectional survey of 1697 patients with breast, prostate, lung or neurological cancer registered with a single NHS authority in Wales. PARTICIPANTS: One thousand and seventy-seven (64%) of patients, aged 18 years or over with cancer diagnosis of at least 3 months, returned analysable questionnaires. Thirty patients were interviewed by telephone. MAIN OUTCOME MEASURES: Number and proportion that had used CAM in the past 12 months, the types of CAM used, expenditure, satisfaction, demographic characteristics, and reasons for using CAM. RESULTS: Five hundred and thirty-four, 49.6% (95% CI 46.6-52.6) of participants, reported using at least one type of CAM during the past 12 months: 221, 16.4% (95% CI 14.3-18.8), had consulted a CAM practitioner (average cost per person, 28 lbs. per month); 166, 15.4% (95% CI 13.4-17.7), indicated using CAM techniques (average cost per person, 16 lbs. per month); 456, 42.3% (95% CI 39.4-45.3), reported using over-the-counter diets, remedies or supplements (average cost per person, 10 lbs. per month). Dissatisfaction with CAM use was low, and most users indicated that they represented value for money. CAM users were more likely to be female, younger, better qualified, and to have used CAM before their current illness than non-users. Patients used CAM primarily for symptom relief and relaxation. CONCLUSIONS: Nearly half the cancer patients in this study had used CAM. A co-ordinated approach to quality assurance, information and advice, and the assessment of risk/benefit and cost effectiveness of CAM use is needed.

Empathy, enablement, and outcome: an exploratory study on acupuncture patients' perceptions.

OBJECTIVES: To conduct an exploratory, retrospective study of acupuncture patients' perceptions of practitioner empathy, patient enablement, and health outcome, and to investigate the associations between them. METHODS: In a retrospective, observational study, questionnaires were distributed to 192 patients randomly selected from a population of 6348 who, several months previously, had participated in a survey of acupuncture safety, and had agreed to be contacted again. The main measures included patients' perceptions of their practitioners' empathy using the Consultation and Relational Empathy Measure, the Patient Enablement Instrument, and the Glasgow Homeopathic Hospital Outcome Scale (measuring change in main complaint and well-being). RESULTS: A total of 143 (74%) patients responded (27% men and 73% women) with an average age of 51 years. Comparisons between the population, the sample selected, and the responding sample showed reasonable equivalence. The majority of patients (71%) were in the middle of an ongoing course of treatment at the time of completing the questionnaires for this study. 36% of patients were attending for reasons of "general well-being," 34% for musculoskeletal problems, 11% for emotional or psychological problems, and 19% for other reasons. Empathy and enablement scores were not influenced by age or reason for attendance, but men showed significantly lower scores than women (p < 0.05). Patient enablement was significantly positively correlated with perception of their practitioners' empathy (Spearman's rho = 0.256, p < 0.01). Enablement in turn was strongly positively correlated with the outcome of both the main complaint (rho = 0.457, p < 0.0001) and improved well-being (rho = 0.521, p < 0.0001). CONCLUSION: Patients' perceptions of consultations with their acupuncturists suggest that their experience of empathy is significantly associated with patient enablement, which in turn is highly correlated with improved self-reported health outcomes.
