Epidemiology of Chronic Pain in the Latium Region, Italy: A Cross-Sectional Study on the Clinical Characteristics of Patients Attending Pain Clinics.

In Italy, chronic pain affects more than a quarter of the population, whereas the average European prevalence is 21%. This high prevalence might be due to the high percentage of Italian people who do not receive treatment, even after the passing of law 38/2010 (the right to access pain management in Italy), which created a regional network for the diagnosis and treatment of noncancer chronic pain. Italian epidemiologic studies on chronic pain are scanty, and this observational, multicenter, cross-sectional study is the first to investigate the clinical characteristics of patients who attended the pain management clinics in the Latium Region, Italy, for the management of their noncancer chronic pain. A total of 1,606 patients (mean age 56.8 years, standard deviation ± 11.4), 67% women, were analyzed. Severe pain was present in 54% of the sample. Women experienced pain and had it in two or more sites more often than men (57% vs. 50%, p = .02; and 55.2% vs. 45.9%, p < .001, respectively). Chronic pain was musculoskeletal (45%), mixed (34%), and neuropathic (21%). In more than 60% of the cases, chronic pain was continuous, and in 20% it had lasted for more than 48 months; long-lasting pain was often neuropathic. Low back (33.4%) and lower limbs (28.2%) were the main locations. Severe intensity of pain was statistically significantly associated with female gender (odds ratio [OR] 1.39; 95% confidence interval [CI] 1.06-1.84); with International Classification of Diseases, Ninth Revision, codes for chronic pain syndrome (OR 2.14; 95% CI 1.55-2.95); and with continuous pain (OR 2.02; 95% CI 1.54-2.66). Neuropathic pain and mixed pain were significantly associated with number of sites, and a trend seemed to be present (OR 2.11 and 3.02 for 2 and 3 + sites; 95% CI 1.59-2.79 and 2.00-4.55, respectively).

The Effect of the Treatment at a Pain Clinic on the Patients' Assessment of Their Pain Intensity and the Incidence of Mental Disorders in the form of Anxiety, Depression, and Aggression.

The aim of the study was to analyze the effect of the treatment given to patients in a pain clinic on their assessment of pain intensity and the incidence of emotional disturbances in the form of anxiety, depression, and aggression. The study was conducted from January 2014 to April 2018 among patients under the care of two Warsaw pain clinics. The study tools were the Hospital Anxiety and Depression Scale-Modified Version (HADS-M) and the Numerical Rating Scale (NRS). The project enrolled 325 patients, with women comprising 60.62% of patients, and the age bracked of 65⁻79 years comprising 39.38% of patient. The major reasons for attending the pain clinic were osteoarticular pain (44.92%) and neuropathic pain (42.77%). The therapy applied lowered the patients' pain intensity (4.98 vs. 3.83), anxiety (8.71 vs. 8.12), aggression (3.30 vs. 3.08), and the overall HADS-M score (18.93 vs. 17.90), which shows that the treatment of both the pain symptoms and the associated emotional disturbances in the form of anxiety and aggression was effective. Sex is a factor affecting pain intensity. The level of mental disorders was influenced by the sex and age of the patients and how long they had been treated in the pain clinics.

Headache Education Active-Waiting Directive: A Program to Enhance Well-Being During Long Referral Wait Times.

OBJECTIVE: The aim of this initiative was to evaluate the clinical impact, patient acceptability, and sustainability of implementing a newly developed evidence-guided migraine education program in an academic headache center. BACKGROUND: Headache is the fifth most common reason for emergency department (ED) visits and accounts for more than 10 million physician visits annually. Successful management of headaches presents a challenge to both primary care providers and neurologists. The catchment area for an academic headache specialty center in a large metropolitan area is over 6 million with an average wait time of over 15 months. This delays diagnosis and impacts patients, thus a Headache Education Active-Waiting Directive (HEAD) was developed to improve patient knowledge and self-care skills among migraine patients awaiting an initial appointment. METHODS: This was a prospective pre- and post-intervention study. English-speaking adults, aged 18-65 years, referred to the Center for Headache at the University of Toronto for headache consultation between May and December 2012, who had not previously been assessed by a headache specialist, were consented and enrolled. Data on Migraine Disability Assessment (MIDAS) with additional questions on emergency visits, lifestyle, and self-efficacy were collected premigraine and postmigraine education program session. RESULTS: Two hundred and forty-eight patients attended the HEAD program and 177 (71%) consented to the study. Detailed predata and postdata were available for 152 participants (mean age 42.5 ± 11.9 years, 86% females); 117/150 (78%) presented with depressive symptoms and 90/146 (62%) presented with anxiety symptoms. One hundred and thirty-seven of 143 (96%) were using headache treatment. Eighty of 137 (58%) were overusing over-the-counter medications and only 21/137 (15%) were on preventative treatment. There was a decrease in the MIDAS scores of participants at postsession testing prior to neurological consultation (pre-MIDAS mean 50.0 ± 64.6 vs post-MIDAS mean 43.2 ± 50.8, P = .046), as well as a decrease in the number of patients requiring ED visit (presession 33 [22%] vs postsession 17 [11%], P = .001). A significant decrease in medication and narcotic overuse after the HEAD program was also observed. Hydration (water intake), morning protein intake, and routine sleep frequency also significantly improved postsession. Controlling for pre-MIDAS score, poor outcome defined as higher post-MIDAS score was statistically associated with lower education level [F(2,149) = 10.88, P = .001]. The majority (144/167, 86%) of the participants found the HEAD program helpful, with 70/167 (42%) very satisfied and 74/167 (44%) somewhat satisfied. One hundred and thirty-two of 167 (79%) felt empowered after attending the education session, and 152/167 (91%) felt that other patients with headache would benefit from this program. CONCLUSIONS: The HEAD program, created to help manage lengthy appointment wait times, was associated with lowering migraine-associated disability, decreasing ED visits, reducing medication and narcotic use and overuse. Education empowers patients to take an active role in their care, especially in regards to improving treatment timing and modifiable lifestyle behaviors. This education program can potentially play a role in early intervention for headache patients especially with chronic migraine and medication overuse headache.

Hospitalization due to acute exacerbation of chronic pain: An intervention study in a university hospital.

BACKGROUND AND AIMS: Hospitalization as a result of acute exacerbation of complex chronic pain is a largely hidden problem, as patients are often admitted to hospital under a variety of specialities, and there is frequently no overarching inpatient chronic pain service dedicated to their management. Our institution had established an inpatient acute pain service overseen by pain physicians and staffed by specialist nurses that was intended to focus on the management of perioperative pain. We soon observed an increasing number of nurse-to-nurse referrals of non-surgical inpatients admitted with chronic pain. Some of these patients had seemingly intractable and highly complex pain problems, and consequently we initiated twice-weekly attending physician-led inpatient pain rounds to coordinate their management. From these referrals, we identified a cohort of 20 patients who were frequently hospitalized for long periods with exacerbations of chronic pain. We sought to establish whether the introduction of the physician-led inpatient pain ward round reduced the number and duration of hospitalizations, and costs of treatment. METHODS: We undertook a retrospective, observational, intervention cohort study. We recorded acute Emergency Department (ED) attendances, hospital admissions, and duration and costs of hospitalization of the cohort of 20 patients in the year before and year after introduction of the inpatient pain service. RESULTS: The patients' mean age was 38.2 years (±standard deviation 13.8 years, range 18-68 years); 13 were women (65.0%). The mode number of ED attendances was 4 (range 2-15) pre-intervention, and 3 (range 0-9) afterwards (p=0.116). The mode bed occupancy was 32 days (range 9-170 days) pre-intervention and 19 days (range 0-115 days) afterwards (p=0.215). The total cost of treating the cohort over the 2-year study period was £733,010 (US$1.12m), comprising £429,479 (US$656,291) of bed costs and £303,531 (US$463,828) of investigation costs. The intervention did not achieve significant improvements in the total costs, bed costs or investigation costs. CONCLUSIONS: Despite our attending physician-led intervention, the frequency, duration and very substantial costs of hospitalization of the cohort were not significantly reduced, suggesting that other strategies need to be identified to help these complex and vulnerable patients. IMPLICATIONS: Frequent hospitalization with acute exacerbation of chronic pain is a largely hidden problem that has very substantial implications for patients, their carers and healthcare providers. Chronic pain services tend to focus on outpatient management. Breaking the cycle of frequent and recurrent hospitalization using multidisciplinary chronic pain management techniques has the potential to improve patients' quality of life and reduce hospital costs. Nonetheless, the complexity of these patients' chronic pain problems should not be underestimated and in some cases are very challenging to treat.

Efficacy and cost-effectiveness: A study of different treatment approaches in a tertiary pain centre.

BACKGROUND: Chronic pain is considered to be a complex phenomenon, involving an interrelation of biological, psychosocial and sociocultural factors. Currently, no single treatment or therapy can address all aspects of this pathology. In our expert tertiary pain centre, we decide to assess the effectiveness of four treatments for chronic pain classically proposed in our daily clinical work: physiotherapy; psycho-education; physiotherapy combined with psycho-education; and self-hypnosis/self-care learning. METHODS: This study included 527 chronic pain patients, with a mean duration of pain of 10 years. Patients were allocated either to one of the four pre-cited treatment groups or to the control group. Pain intensity, quality of life, pain interference, anxiety and depression were assessed before and after treatment. RESULTS: This study revealed a significant positive effect on pain interference and anxiety in patients included in the physiotherapy combined with psycho-education group, after 20 sessions spread over 9 months of treatment. The most prominent results were obtained for patients allocated to the self-hypnosis/self-care group, although they received only six sessions over a 9-month period. These patients showed significant benefits in the areas of pain intensity, pain interference, anxiety, depression and quality of life. CONCLUSIONS: This clinical report demonstrates the relevance of biopsychosocial approaches in the improvement of pain and psychological factors in chronic pain patients. The study further reveals the larger impact of self-hypnosis/self-care learning treatment, in addition to a cost-effectiveness benefit of this treatment comparative to other interventions.

Prevalence and impact on quality of life of post-herpetic neuralgia in French medical centers specialized in chronic pain management: the ZOCAD study.

OBJECTIVES: (1) We had for aim to determine the rate of patients consulting for post-herpetic neuralgia (PHN) in centers specialized in the management of chronic pain, (2) to assess the burden of PHN, (3) to compare the impact of PHN between new (newly consulting for PHN) and known (already treated by pain specialists) patients. PATIENTS AND METHODS: We conducted a prospective multicenter observational study including all chronic pain outpatients consulting for 3 consecutive weeks. The impact of PHN was assessed with the ZBPI, SF12, HADS, and a non-validated disability questionnaire. RESULTS: Among the patients, 4518 consulted 54 specialized centers from January 24th to July 21st 2008: 2.6% of patients (but 10.9% of patients 70 years of age or more) reported PHN. The acute herpes zoster episode had occurred more than 13.3 months before inclusion for half of the patients. 108 of the 118 PHN patients (33 new and 75 known) completed the questionnaires. Their mean scores were 3.7 (SD, 2.6) for ZBPI and 34.4 (SD, 10.9) and 55.9 (SD, 11.4) for SF12 PCS and MCS; 38% and 42% of PHN patients had HADS anxiety and depression scores > 10. Nearly all PHN patients had received antiepileptic and analgesic drugs. Tricyclic antidepressants and lidocaine patches were more frequently administered to known than to new patients. Pain relief was more effective for known than for new patients. CONCLUSIONS: PHN is a frequent cause of visit in French medical centers specialized in chronic pain management long after the rash has disappeared, and a reason for treatment with drugs that should be prescribed cautiously in elderly patients.

[Gender-based differences in the management of low back pain].

BACKGROUND: Low back pain (LBP) is a well-known reason people worldwide seek medical help and it is a Leading cause of chronic pain and disability among people of working age. Recent research reveals that the female gender is not only a risk factor for developing LBP but it may also influence the management of this common condition. OBJECTIVES: Our objective was to evaluate gender-related differences in the management of LBP patients in a specialized hospital-based chronic pain unit. METHODS: A cross-sectional survey was carried out through telephone interviews and the hospital computerized database (N = 129). Socio-demographic, Lifestyle, occupational and medical variables were collected, and their association with the frequency of use of five different diagnostic and/or therapeutic modalities was examined using gender stratification. RESULTS: After adjustment for age, religion, socioeconomic data and the number of co-morbid conditions, women were more prone to poly-pharmacy of analgesic medications prescribed in the previous year compared to men (p = 0.024) and exhibited an increased rate of treatment cessations due to adverse effects (p < 0.001). Interestingly, while women tended to utilize more healthcare services besides the pain clinic (p = 0.097), men tended on average to have more visits than women to the pain clinic for their complaints (p = 0.019). Among those who applied for insurance compensation for LBP-related disability, women exhibited increased use of imaging procedures compared to men (p = 0.038). CONCLUSIONS: This cross-sectional study reveals gender-related differences in management and health services utilization for treatment of LBP in the chronic pain clinic. If confirmed in other centers, these findings should inspire gender-sensitive resource management of the treatment of chronic pain patients. Moreover, the findings suggest that increased awareness of gender bias when seeking insurance compensation for LBP-related disability is warranted.

Access to public healthcare services and waiting times for patients with chronic nonmalignant pain: feedback from a tertiary pain clinic.

Evaluation of healthcare services by patients is an essential component of quality improvement. We studied association between patient satisfaction and accessibility of healthcare services to patients with chronic nonmalignant pain. A hundred patients from the Pain Clinic, Split University Hospital Center, Split, Croatia, completed a 27-item questionnaire about their condition, duration of chronic pain treatment, access to healthcare, waiting times for various healthcare services, and their satisfaction with the pain clinic and health system. Patients were referred to the pain clinic after median of 4.5 years of chronic nonmalignant pain duration. Median waiting time for pain clinic appointment, seeing a specialist and performing diagnostic procedures was 10, 30 and 90 days, respectively. However, some patients waited for an appointment to a specialist and diagnosis for up to one year. Negative association was found between waiting time for pain clinic appointment and healthcare system grade (r = -0.34, P = 0.02). Patient suggestions for improving pain clinic were more staff, better approach to each patient, and better organization. In conclusion, access to public healthcare for patients with chronic nonmalignant pain should be better to improve patient satisfaction and provide better care.

Racial disparities in the monitoring of patients on chronic opioid therapy.

Despite well-documented racial disparities in prescribing opioid medications for pain, little is known about whether there are disparities in the monitoring and follow-up treatment of patients who are prescribed opioid medications. We conducted a retrospective cohort study to examine whether there are racial differences in the use of recommended opioid monitoring and follow-up treatment practices. Our sample included 1646 white and 253 black patients who filled opioid prescriptions for noncancer pain for ≥ 90 consecutive days at the Veterans Affairs Pittsburgh Healthcare System pharmacy in fiscal years 2007 and 2008. Several opioid monitoring and follow-up treatment practices were extracted from electronic health records for a 12-month follow-up period. Findings indicated that 26.3% of patients had opioid agreements on file, pain was documented in 71.7% of primary care follow-up visits, urine drug tests were administered to 49.3% of patients, and 21.2% and 4.2% of patients were referred to pain and substance abuse specialists, respectively. Racial differences were observed in several of these practices. In adjusted comparisons, pain was documented less frequently for black patients than for white patients. Among those who had at least 1 urine drug test, black patients were subjected to more tests, especially if they were on higher doses of opioids. Compared with white patients, black patients were less likely to be referred to a pain specialist and more likely to be referred for substance abuse assessment. Addressing disparities in opioid monitoring and follow-up treatment practices may be a previously neglected route to reducing racial disparities in pain management.

Non-cardiac chest pain: time to extend the rapid access chest pain clinic?

Non-cardiac chest pain is common. It has a low risk of coronary events, but causes considerable physical and social disability and inappropriate health-care usage. It is a heterogeneous condition, which may be caused by or associated with gastro-oesophageal, musculoskeletal or psychiatric abnormalities and sustained by psychological factors including catastrophisation, avoidance behaviour and abnormal help-seeking. These may coexist and their relative contributions may vary in different patients or at different times in an individual patient. The absence of a unitary cause probably explains why treatment studies show only moderate success. An individualised biopsychosocial approach takes account of all causative and sustaining processes and has been shown to work in pain syndromes at other sites. We suggest that this approach should be tried for chest pain using a multidisciplinary clinic model including cardiologists, psychologists and nurses linked with a Rapid Access Chest Pain Clinic.

[Identifying and prioritising adverse episodes and failures related to patient safety in Pain Treatment Units]. / Identificación y priorización de episodios adversos y fallos relacionados con la seguridad del paciente en las Unidades de Tratamiento del Dolor.

OBJECTIVES: An expert group coordinated by the Andalusian School of Public Health identified the most serious and frequent adverse events in Pain Treatment Units (PTU), as well the failures and underlying causes, as a prior step to preparing preventive actions. The aims of the project were to identify potential adverse events in Pain Treatment Units, identify failures and their underlying causes, and prioritise these failures according to a failure modes and effects analysis (FMEA) tool. MATERIAL AND METHODS: The method employed consisted of a literature search, the selection of an expert group with experience in PTU, creating a catalogue of adverse events using the generation of ideas technique, and putting the FMEA and Risk Priority Index tools into practice. RESULTS: Up to 66 types of adverse events were identified associated with; medication (30), invasive techniques (15), care process (10), patient information and education (6), and clinical practice (5). It was found that up to 101 failures could be triggered by these adverse events, and that 242 causes could lead to these failures. CONCLUSIONS: The results indicated the need to work principally in two directions, improving the care process in the PTU (the health care organisation), and the professional work, this latter having two aspects, improving the clinical practice, and increase professional skills by means of specific training. Communication, whether inter-professional or inter-department, or with the patient and their family, is identified as a key aspect for improvement.

Work-related chronic low back pain-return-to-work outcomes after referral to interventional pain and spine clinics.

STUDY DESIGN: A retrospective cohort study. OBJECTIVE: To evaluate return-to-work outcomes in patients with chronic, work-related low back pain referred to pain treatment centers and/or spine clinics (PTCs/SCs). SUMMARY OF BACKGROUND DATA: Return-to-work outcomes in cases of work-related chronic low back pain after referral to PTCs and/or SCs have not been previously studied. METHODS: A retrospective chart review of 230 consecutive patients was conducted from an occupational medicine program. Of these, 122 patients were referred to a PTC/SC and 108 patients were not. Multivariate logistic regression was used to develop a model to predict improvement in functional status and pain level after 1 year. RESULTS: At the 1-year evaluation, there was functional improvement in the nonreferral group (P < 0.001) and no change in the referral group (P = 0.21). The change in pain level was similar. Time from injury to initial evaluation seemed to be the major factor contributing to poor outcomes in both groups. CONCLUSION: Referral to a PTC/SC did not yield improved functional outcomes in this cohort. A major factor contributing to this finding was the length of time to referral to PTC/SC after the initial injury.

The Canadian STOP-PAIN project - Part 2: What is the cost of pain for patients on waitlists of multidisciplinary pain treatment facilities?

PURPOSE: The Canadian STOP-PAIN Project was designed to document the human and economic burden of chronic pain in individuals on waitlists of Multidisciplinary Pain Treatment Facilities (MPTF). This paper describes the societal costs of their pain. METHODS: A subgroup of 370 patients was selected randomly from The Canadian STOP-PAIN Project. Participants completed a self-administered costing tool (the Ambulatory and Home Care Record) on a daily basis for three months. They provided information about publicly financed resources, such as health care professional consultations and diagnostic tests as well as privately financed costs, including out-of-pocket expenditures and time devoted to seeking, receiving, and providing care. To determine the cost of care, resources were valued using various costing methods, and multivariate linear regression was used to predict total cost. RESULTS: Overall, the median monthly cost of care was $1,462 (CDN) per study participant. Ninety-five percent of the total expenditures were privately financed. The final regression model consisted of the following determinants: educational level, employment status, province, pain duration, depression, and health-related quality of life. This model accounted for 35% of the variance in total expenditure (P < 0.001). CONCLUSION: The economic burden of chronic pain is substantial in patients on waitlists of MPTFs. Consequently, it is essential to consider this burden when making decisions regarding resource allocation and waitlist assignment for a MPTF. Resource allocation decision-making should include the economic implications of having patients wait for an assessment and for care.

Urine drug testing in the treatment of chronic noncancer pain in a Kentucky private neuroscience practice: the potential effect of Medicare benefit changes in Kentucky.

BACKGROUND: Because the symptoms of drug misuse are nonspecific and difficult to detect, pain physicians have relied heavily on the results of urine drug tests to diagnose and treat chronic noncancer pain in patients who are prescribed controlled substances. However, changes in Medicare local carrier determinations for Medicare Part B providers in Connecticut, Indiana, Kentucky, and New York went into effect on July 1, 2009, whereby qualitative drug screening was no longer recognized as medically reasonable and necessary in the treatment of patients with chronic noncancer pain unless the patient presents with suspected drug overdose. STUDY DESIGN: A retrospective review of urine drug testing services. OBJECTIVE: To determine the extent of urine drug testing in patients with chronic noncancer pain in a large, Kentucky neuroscience practice offering pain management services combined with neurologic and neurosurgical services to better understand the potential effects of recent changes to Medicare benefits. METHODS: An audit of services provided during 2007 was conducted using computer software. OUTCOME MEASURES: Outcome measures included the number of practice services, number of urine drug tests by payor, and the number of noncompliant patients by payor who self-released from care. RESULTS: Urine drug tests represented approximately 18.2% of professional medical services rendered in 2007 to patients with a diagnosis of chronic noncancer pain. Of these, UDTs represented approximately 22.2% of services provided to Medicare patients and 24.6% of services provided to Medicaid patients. In 2007, 2,081 patients with noncompliant UDTs self released from the practice against medical advice. Of these, 23.1% were enrolled in Medicare and 47.5% were enrolled in Medicaid. Approximately 40% of patients were referred to the CARE Clinic on the basis of noncompliance as indicated by UDT and/or behavioral health issues. Of these, approximately 50% remained in treatment. Urine drug tests were also instrumental in revealing that 19.6% of patients showed signs of drug abuse or addiction. Of these patients, approximately 60% were government insured. LIMITATIONS: Not a prospective, double-blinded study. We approximated the proportion of patients potentially affected by drug abuse or addiction as the percentage of patients self releasing from medical care. CONCLUSION: In 2007, UDTs were used as an effective tool in adherence monitoring in a private neuroscience practice in Kentucky that offers pain management services combined with neurologic and neurosurgical services. UDTs were instrumental in referring 40% of patients for evaluation and treatment by behavioral health and addiction medicine specialists. UDTs were also instrumental in discovering signs of drug abuse or addiction in 19.6% of patients. Of these patients, approximately 60% were government insured. Should the objective and reliable sign offered by UDTs be eliminated from the physician's toolbox, the physician's ability to accurately diagnose and treat these patients could be impaired.

A national survey of American Pediatric Anesthesiologists: patient-controlled analgesia and other intravenous opioid therapies in pediatric acute pain management.

BACKGROUND: The influence of patient characteristics, institutional demographics, and published practice guidelines on the provision of IV opioid analgesia, particularly as delivered through a patient-controlled analgesia (PCA) delivery device, to pediatric patients is unknown. METHODS: We sent a national, web-based, descriptive survey of pediatric pain management practice to select members of the Society for Pediatric Anesthesia to assess institutional demographics, availability and implementation of IVPCA and PCA by proxy, and recalled occurrence of serious and life-threatening opioid-related side effects. RESULTS: Data from respondents at 252 institutions throughout the United States were collected and analyzed. Sixty-nine percent of respondents practiced in a children's hospital or children's center within a general hospital, and 51% of institutions had a pediatric pain service. Virtually all pediatric pain services (91%) were administered by departments of anesthesiology. Pediatric pain service availability correlated with the number of pediatric beds. IVPCA was available to pediatric patients at 96% of institutions surveyed, whereas IVPCA by proxy was available at only 38%. Eleven percent of respondents reported that their hospital no longer provided IVPCA by proxy as a result of the 2004 Joint Commission on Accreditation of Hospitals Sentinel Event Warning. Instructional material concerning IVPCA was provided to patients or their families by 40% of institutions. IVPCA orders were handwritten by 55% of respondents, despite 39% having computerized provider order entry systems. Ninety percent of respondents reported using pulse oximetry monitoring when patients were administered IVPCA. Forty-two respondents recalled patients having received naloxone to counteract the cardiopulmonary side effects of opioids during the year before receipt of the survey. Eight respondents recalled patient deaths having occurred over the past 5 years in patients receiving IVPCA, IVPCA by proxy, and continuous non-IVPCA opioid infusions. CONCLUSIONS: Although IVPCA was available to pediatric patients at most institutions surveyed, prescribing practices and supervision of pediatric pain management were influenced by patient characteristics, institutional demographics, and published national guidelines. Recalled life-threatening events were reported in conjunction with all modes of opioid infusion therapy. Interventions that might diminish the incidence of adverse events but are not used to their fullest extent include improved education and implementation of systems designed to minimize human error involved in the prescribing of opioids. Providing a more accurate accounting of complications would require institutions to participate in a prospective data-collecting consortium designed to track both the incidence of therapy and associated complications.

Long-term effects of a sensitisation campaign on migraine: the Casilino study.

In 2003, we conducted a sensitisation campaign on migraine in the Casilino district of Rome, by sending a letter with the ID Migraine test to all the households and placing posters in the GPs' waiting room. Out of 195 headache patients recruited, 92% had migraine while 73% had never consulted a physician for headache. The aim of this study was to evaluate the long-term impact of this campaign. The follow-up was performed by a telephone interview. The questionnaire considered the characteristics of headache, quality of life, preventive and acute treatments, drug efficacy, comorbidity and subjective usefulness of the campaign. Of the 179 migraineurs, 90.5% (mean age 40.7 +/- 16.5, 139 females) were included in the follow-up. An improvement was observed in mean pain intensity (-13.9%; p < 0.0001) and mean HIT-6 score (-6.1%; p = 0.0003). The campaign was considered to be useful by 63.6% of cases, while 66.1% reported an improvement in their clinical status. Improved patients showed a decreased mean number of days with headache per month (-51.7%; p < 0.0001), pain intensity (-21.8%; p < 0.0001), headache duration (-18.1%; p = 0.0008)and HIT-6 score (-11.7%; p < 0.0001). Our data suggest that the effects of a "single shot" campaign are beneficial not only in a short-term perspective, but even in the longterm. Moreover, the lack of benefit in more severe cases suggests that such patients should not be treated by GPs alone: patients in whom the HIT-6 score, frequency,severity or duration of headache worsen should be promptly referred to the headache clinic.

Spinal cord stimulation for failed back surgery syndrome: outcomes in a workers' compensation setting.

Questions remain concerning effectiveness and risks of spinal cord stimulation (SCS) for chronic back and leg pain after spine surgery ("failed back surgery syndrome" [FBSS]). This prospective, population-based controlled cohort study evaluated outcomes of workers' compensation recipients with FBSS who received at least a trial of SCS (SCS group, n=51) versus those who (1) were evaluated at a multidisciplinary pain clinic and did not receive SCS (Pain Clinic, n=39) or (2) received neither SCS nor pain clinic evaluation (Usual Care, n=68). Patients completed measures of pain, function, medication use, and work status at baseline and 6, 12, and 24 months later. We also examined work time loss compensation over 24 months. Few (<10%) patients in any group achieved success at any follow-up on the composite primary outcome encompassing less than daily opioid use and improvement in leg pain and function. At 6 months, the SCS group showed modestly greater improvement in leg pain and function, but with higher rates of daily opioid use. These differences disappeared by 12 months. Patients who received a permanent spinal cord stimulator did not differ from patients who received some pain clinic treatment on the primary outcome at any follow-up (<10% successful in each group at each follow-up) and 19% had them removed within 18 months. Both trial and permanent SCS were associated with adverse events. In sum, we found no evidence for greater effectiveness of SCS versus alternative treatments in this patient population after 6 months.

Opioid use in an Israeli health maintenance organization: 2000-2006.

OBJECTIVE: The objective of this study was to assess opioid use during 7 years (2000-2006) among Clalit Health Services (CHS) members. DESIGN: Purchasing data of opioids authorized for use in Israel were obtained from the computerized databases of CHS. Patient demographics and cancer morbidity were also extracted. The data were analyzed by converting the purchased opioids to oral morphine equivalents (OMEs). SETTING: CHS is the largest health maintenance organization in Israel (3,774,600) and insures almost 54% of the Israeli population. PATIENTS: All CHS members who purchased an opioid at least once during the 7-year study period (2000-2006). INTERVENTION: There were no interventions in this study. OUTCOME MEASURES: The outcome measures of this study were total OME purchased per year, OME (mg) per capita/per year, and OME (mg) daily dose. RESULTS: There were 119,562 patients who purchased an opioid at least once (3.2% of CHS population). Of them, 57.4% were women, 69.0% aged 65 years and above (average age 56.05 years +/- 26.7), 7.7% purchased opioids for more than 12 months, and 81.3% purchased opioids for only 1-4 months. A 96% increase in total OME purchased was found between 2000 and 2006 (from 56.4 kg to 110.6 kg). The annual OME purchased per capita increased from 15.7 mg in the year 2000 to 29.3 mg in 2006. The total number of patients who received at least one opioid prescription increased by 60%, while the growth in total number of CHS members was smaller (4.8%). CONCLUSIONS: There is a growing use of opioids at CHS during the 7-year period, a potential indicator of the progress made in improving accessibility and availability of opioids in our health care organization in Israel.

Management of low back pain in primary care prior to multidisciplinary functional restoration: a retrospective study of 72 patients.

OBJECTIVE: Chronic low back pain is a major socioeconomic health issue, due to the high direct (healthcare) and indirect (sick leave) costs. The aim of the present study was to describe the primary care management of low back pain patients prior to their inclusion in a multidisciplinary functional restoration network. METHODS: A descriptive, retrospective, questionnaire-based survey of the general practitioners dealing with 72 low back pain patients. RESULTS: Patients had been monitored by their general practitioner for an average of four years, with a mean frequency of eight appointments per year per patient. Ninety-three percent and 60% of the patients had been referred to a rheumatologist and a surgeon, respectively. Ninety-eight percent had had lumbar radiographies, 80% had undergone a computed tomography scan and 64% had undergone magnetic resonance imaging. The most commonly prescribed medications were anti-inflammatories and first- or second-line analgesics. Thirty percent had already received morphine analgesics and 50% had taken antidepressants. Thirty-two percent had undergone lumbar surgery. Physiotherapy was frequently reported and, indeed, 6% of patients had participated in over 100 sessions. Total sick leave averaged 8.25 months over the study's follow-up period. CONCLUSION: The time interval before referral to a multidisciplinary care team is long and so GPs should be encouraged and helped to organize this process earlier. It is also essential to determine factors which predict progression to chronic LBP.
