Patient-reported improvements of pain, disability, and health-related quality of life following chiropractic care for back pain - A national observational study in Sweden.

BACKGROUND: Chiropractic care is a common but not often investigated treatment option for back pain in Sweden. The aim of this study was to explore patient-reported outcomes (PRO) for patients with back pain seeking chiropractic care in Sweden. METHODS: Prospective observational study. Patients 18 years and older, with non-specific back pain of any duration, seeking care at 23 chiropractic clinics throughout Sweden were invited to answer PRO questionnaires at baseline with the main follow-up after four weeks targeting the following outcomes: Numerical Rating Scale for back pain intensity (NRS), Oswestry Disability Index for back pain disability (ODI), health-related quality of life (EQ-5D index) and a visual analogue scale for self-rated health (EQ VAS). RESULTS: 246 back pain patients answered baseline questionnaires and 138 (56%) completed follow-up after four weeks. Statistically significant improvements over the four weeks were reported for all PRO by acute back pain patients (n = 81), mean change scores: NRS -2.98 (p < 0.001), ODI -13.58 (p < 0.001), EQ VAS 9.63 (p < 0.001), EQ-5D index 0.22 (p < 0.001); and for three out of four PRO for patients with chronic back pain (n = 57), mean change scores: NRS -0.90 (p = 0.002), ODI -2.88 (p = 0.010), EQ VAS 3.77 (p = 0.164), EQ-5D index 0.04 (p = 0.022). CONCLUSIONS: Patients with acute and chronic back pain reported statistically significant improvements in PRO four weeks after initiated chiropractic care. Albeit the observational study design limits causal inference, the relatively rapid improvements of PRO scores warrant further clinical investigations.

Patients' experiences and perceptions of integrative care for back and neck pain.

CONTEXT: Conventional guidelines in Sweden recommend primary care management for back and neck pain, yet these two conditions are the most common ones for which patients use complementary therapies. Despite the recent growth of integrative medicine (IM) in different clinical, academic, and societal contexts, few studies have defined and investigated comprehensive models of integrative care as compared to conventional management, especially using randomized clinical trials. OBJECTIVE: The study explores patients' experiences and perceptions when receiving conventional or integrative care in the management of back and neck pain. DESIGN: The research team conducted this study within a larger interventional study. In that study--a pragmatic randomized clinical pilot trial--the team developed a model for integrative medicine that combines complementary therapies that have an emerging evidence base and conventional treatments for patients with nonspecific back and neck pain. The research team implemented the model and compared the results for integrative care to results for conventional primary care. The current qualitative study included 11 focus-group discussions: conventional care (n= 5) and integrative care (n=6). SETTING: The research team implemented the interventional study in south suburban Stockholm, an area with higher unemployment, lower incomes, and receipt of more welfare support and sickness benefits compared to the average levels in Stockholm. PARTICIPANTS: The participants in the focus-group discussions were volunteers drawn from the larger randomized clinical trial. OUTCOME MEASURES: The research team transcribed all discussions from the focus groups verbatim and used latent content analysis to evaluate the data. RESULTS: Receiving diagnostic support and excluding pathology were strong reasons for participants to seek conventional care. Participants reported that they found conventional management to be reductionistic, with a focus on disease, and a lack of accessibility, time, and guidance. In contrast, participants reported that integrative care was holistic, whole-person management and facilitated increased treatment response, support, empowerment, and self-help strategies. Participants, however, perceived integrative care to be challenging because of additional treatment costs with complementary therapies and collaborative shortcomings between integrative and conventional practitioners generally. CONCLUSION: Integrative care represents a combination of valuable conventional medical diagnosis with empowering self-help strategies for some patients with nonspecific back and neck pain in Swedish primary care. Future studies should also investigate experiences and perceptions in the longer term from the perspective of patients, caregivers, and health systems.

Hyperbaric oxygen reduced size of chronic leg ulcers: a randomized double-blind study.

To evaluate the effect of hyperbaric oxygen therapy on chronic wound healing, 16 otherwise healthy patients who had nondiabetic, chronic leg ulcers with no large vessel disease were included in a double-blind study. Patients were grouped according to age and then randomly assigned to two groups breathing either air or oxygen at 2.5 atmospheres of absolute pressure for 90 minutes 5 days per week for a total of 30 treatments. The wound area was copied onto transparent film covering the wound and then measured using only one matching wound from each patient. The mean decrease of the wound areas at weeks 2, 4, and 6 in the oxygen group were 6 percent (SD +/- 14), 22 percent (SD +/- 13), and 35.7 percent (SD +/- 17), respectively, and in the air group, 2.8 percent (SD +/- 11), 3.7 percent (SD +/- 11), and 2.7 percent (SD +/- 11), respectively, giving a p value less than 0.05 at week 4, and a p value less than 0.001 at week 6 between the groups using the Mann-Whitney U test. These data indicate that hyperbaric oxygen therapy may be used as a valuable adjunct to conventional therapies when nondiabetic wounds do not heal.
