10 RESEARCH BRIEFS Journal Grab Keeping patients satisifed OPIOID prescriptions for chronic pain have been rising. While there are concerns about this, an American study has ascertained whether it satisfi es patients. Data came from a national survey. The sample involved 19,500 patients with chronic musculoskeletal problems, including 2560 who were taking prescription opioids. There were signifi cant diff erences between the users and non-users. People on opioids were in poorer health and reported more severe pain. After adjusting for these factors, the opioid users were 32% more likely to be very satisfi ed with their care. Moderate and heavy users were more likely than other users to be satisfi ed.

Research from regional NSW has studied how out-of-hours general practice services aff ect emergency departments. All patients who attended an after-hours GP clinic in Bathurst were invited to partic- ipate in a survey. To assess their satisfaction, they were surveyed again within two weeks. A total of 827 patients presented in a fi ve- month period and 219 completed the survey. According to 76% of the patients, their visit was essential. The GPs in the clinic considered 87% of the presentations to be appropriate. Only 3% were not appropriate. The presenting prob- lem was satisfactorily resolved in 79% of cases. Only 2% of the patients needed to be referred to hospital. THE majority of demen- tia cases are not explained by risk fac- tors such as diabetes and hypertension. A systematic review was conducted to look for potential risk factors in the environment. The review included 60 studies, including 16 on aluminium, which found moderate evidence of an association. For most metals, however, the evidence was weak. The eff ect of sele- nium supplements was uncertain. Air pollution was associated with an increased risk. The evi- dence was stronger for nitrous oxides and par- ticulate matter than for environmental tobacco smoke. Diesel fumes had no eff ect. There were several studies of fertilisers and pesticides. While some found no eff ect, there was moderate evidence of a link with dementia. Three high-quality studies found an associ- ation between low con- centrations of vitamin D and dementia risk. COMMENT COMMENT Observational data need to be interpreted with caution. A diff erent analysis of the same data did not fi nd a greater pro- pensity for heavy opioid users to be satisfi ed with their care. It could be that the patients are satisfi ed because opioids relieve their physical pain. Alternatively, they could have become dependent and the prescriptions are meeting their desire for opioids. A complexity in the decision to prescribe is how doctors are paid. If remuneration is partly based on reports of patient satis- faction there may be a temptation to give patients what they want rather than what they need. After-hours clinics lower ED visits BMC FAM PRAC 2017: 18:86 FAR RIGHT BMC GERIATICS 2016; 16:175 The clinic clearly saved the emergency depart- ment a lot of work. If the clinic had not been available, 60% of the patients said they would have gone to the hospital. That fi gure could have been even higher if the clinic had charged for consul- tations. COMMENT The problem with cross-sectional studies is that they cannot confi rm a cause, although they can give clues for further research.
