Illness perceptions and burden of disease in fibromyalgia.

INTRODUCTION: Fibromyalgia (FM) is a chronic syndrome that usually develops midlife. It is associated with a high burden of illness that causes significant disability. Areas covered: Diagnosis can be challenging, given the diverse clinical presentation among those with FM. Therefore, the typical health care journey for a patient with FM is lengthy and complex. There is no acknowledged treatment algorithm for FM, prescribing patterns vary markedly, and patients are likely to receive suboptimal or inappropriate pharmacotherapy. Expert commentary: Major improvements in FM recognition and management are urgently needed. Long-term prospective studies should be conducted to improve the understanding of the course of illness and to determine whether early diagnosis and intervention can reduce the severity and duration of symptoms.

Opioid Prescribing Laws and Emergency Department Guidelines for Chronic Non-Cancer Pain in Washington State.

Rising mortality rates, increased opioid prescription abuse, and a perceived need to provide practitioners with structured guidance in opioid prescribing have prompted the Washington State Legislature to establish new legal standards of practice regarding chronic non-cancer pain management. Clinicians are required to conduct a detailed physical examination and health history prior to treatment. Risk assessments for abuse and detailed periodic reviews of treatment are required at least every 6 months. Those considered "high risk" or who have significant psychiatric comorbidities will be required to sign and follow a written agreement or pain contract, obtain their pain prescriptions from a single provider, and submit to biological drug screening. Unless an exemption exists, patients prescribed > 120 mg of morphine-equivalents daily, considered severe pain nonresponders, necessitating dosage escalation, diagnosed with multifaceted mental health-related comorbidities, demonstrating diagnostic ambiguity, and/or requiring significant treatment individualization are referred to a pain specialist. Episodic care settings should refrain from supplying opioids to chronic pain patients whenever possible. The ER is for Emergencies coalition instituted the Seven Best Practices program throughout the state to reduce unnecessary visits, coordinate prescribing practice, reduce Medicaid expenditures, and improve overall patient care. The state reported approximately $33.65 million in savings in 2013 through the use of these practices and converting Medicaid participants from fee-for-service to managed care plans. Similar legislation to complement clinical practice guidelines is expected to be enacted in other states. It is vital that practitioners comprehend the new guidelines and make appropriate adjustments in their opioid prescribing habits.

Dosing considerations with transdermal formulations of fentanyl and buprenorphine for the treatment of cancer pain.

Opioids continue to be first-line pharmacotherapy for patients suffering from cancer pain. Unfortunately, subtherapeutic dosage prescribing of pain medications remains common, and many cancer patients continue to suffer and experience diminished quality of life. A large variety of therapeutic options are available for cancer pain patients. Analgesic pharmacotherapy is based on the patient's self-report of pain intensity and should be tailored to meet the requirements of each individual. Most, if not all, cancer pain patients will ultimately require modifications in their opioid pharmacotherapy. When changes in a patient's medication regimen are needed, adequate pain control is best maintained through appropriate dosage conversion, scheduling immediate release medication for withdrawal prevention, and providing as needed dosing for breakthrough pain. Transdermal opioids are noninvasive, cause less constipation and sedation when compared to oral opioids, and may improve patient compliance. A relative potency of 100:1 is recommended when converting the patient from oral morphine to transdermal fentanyl. Based on the limited data available, there is significant interpatient variability with transdermal buprenorphine and equipotency recommendations from oral morphine of 75:1-110:1 have been suggested. Cancer patients may require larger transdermal buprenorphine doses to control their pain and may respond better to a more aggressive 75-100:1 potency ratio. This review outlines the prescribing of transdermal fentanyl and transdermal buprenorphine including how to safely and effectively convert to and use them for those with cancer pain.

Fibromyalgia: disease synopsis, medication cost effectiveness and economic burden.

Fibromyalgia (FM) primarily affects women, and it is increasingly recognized by health care providers as more patients seek assistance for their chronic pain conditions. FM patients suffer from reduced quality of life, daily functioning and productivity. A single FM patient can cost society tens of thousands of dollars each year, with the overall expense increasing alongside disease severity. Indirect costs account for the majority of total expenditures and involve losses in productivity, reduced work hours, absenteeism, disability, unemployment, early retirement, informal care and other out-of-pocket costs. Health care utilization increases in concert with the severity of illness. Moreover, FM patients often have several comorbid illnesses (e.g. depression, anxiety and sleep disturbances), resulting in extreme escalation of overall health care expenditures. Medications with the best efficacy in the treatment of FM include the tricyclic antidepressants amitriptyline and nortriptyline, cyclobenzaprine (a skeletal muscle relaxant), tramadol, duloxetine, milnacipran, pregabalin and gabapentin. Corticosteroids, nonsteroidal anti-inflammatory drugs, benzodiazepines and opioid analgesics, with the exception of tramadol, are not considered efficacious. Medication selection should be individualized and influenced by the severity of illness and the presence of comorbidities and functional disabilities.

α1-Proteinase inhibitor (human) in the treatment of hereditary emphysema secondary to α1-antitrypsin deficiency: number and costs of years of life gained.

BACKGROUND: α(1)-Antitrypsin deficiency (α-ATD) is a disorder inherited in an autosomal recessive pattern, with co-dominant alleles known as the protease inhibitor system (Pi). The main function of α(1)-antitrypsin (α-AT) is to protect the lungs against a powerful elastase released from neutrophil leucocytes. α-ATD typically presents with a serum α-AT level of <50 mg/dL. In severe α-ATD, phenotype PiZZ, protection of the lungs is compromised, leading to an accelerated decline in forced expiratory volume in 1 second (FEV(1)). As a result, a patient may develop pulmonary emphysema of the panacinar type at a young age (third to fourth decades of life), with cigarette smoking being the most significant additional risk factor. It has been shown that weekly or monthly infusion of human α-AT is effective in raising serum α-AT levels to desired levels (>80 mg/dL), with few, if any, adverse effects. OBJECTIVE: The present study was designed to discern the number of years of life gained, and the expense per year of life gained, associated with use of α-AT augmentation therapy (α(1)-proteinase inhibitor [human]), relative to 'no therapeutic intervention' in persons with α-ATD. METHODS: Monte Carlo simulation (MCS) was used to: (i) estimate the number of years of life gained; and (ii) estimate the health service expenditures per year of life gained for persons receiving, or not receiving, α-AT augmentation therapy. MCS afforded a decision-analytical framework parameterized with both stochastic (random) and deterministic (fixed) components, and yielded a fiscal risk-profile for each simulated cohort of interest (eight total: by sex, smoking status [non-smoker; or past use (smoker)]; and use of α-AT augmentation therapy). The stochastic components employed in the present inquiry were: (i) age-specific body weight, and height; (ii) age-specific mortality; and (iii) the probability distribution for receipt of a lung transplant, as a function of FEV(1). The deterministic components employed in the present inquiry were: (i) age in years for the simulated cohort; (ii) outlays for α-AT augmentation therapy; (iii) health service expenditures associated with receipt of a lung transplant; (iv) annual decline in FEV(1); (v) percent predicted FEV(1); (vi) initiation of α-AT augmentation therapy as a function of percent predicted FEV(1); (vii) need for a lung transplant as a function of percent predicted FEV(1); (viii) annual rate of lung infection; and (ix) mortality as a function of percent predicted FEV(1). Results are reported from a payer perspective ($US, year of costing 2010). RESULTS: Receipt of α-AT augmentation therapy was associated with a significant increase (p < 0.05) in years of life gained, with female smokers gaining an estimated mean 7.14 years (cost per year: $US248 361 [95% CI 104 531, 392 190]); female non-smokers gained an estimated mean 9.19 years (cost per year: $US160 502 [95% CI 37 056, 283 947)]); male smokers gained an estimated mean 5.93 years (cost per year: $US142 250 [95% CI 48 467, 236 032]); and male non-smokers gained an estimated mean 10.60 years (cost per year: $US59 234 [95% CI 20 719, 97 548]). CONCLUSION: Use of α-AT augmentation therapy was associated with an increase in years of life gained by sex and history of tobacco use, and at a cost per year of life gained comparable to that of other evidenced-based interventions.

Ethnicity/race, use of pharmacotherapy, scope of physician-ordered cholesterol screening, and provision of diet/nutrition or exercise counseling during US office-based visits by patients with hyperlipidemia.

BACKGROUND: Elevation of serum cholesterol, or hyperlipidemia, is recognized as one of the major modifiable risk factors in the development of atherosclerosis and cardiovascular disease. On a US population basis, there has been a downward trend in total- and LDL-cholesterol levels, and an increase in cholesterol screening. Nevertheless, previous research suggests that there remain racial/ethnic disparities in the access to and quality of care for hyperlipidemia. OBJECTIVE: The aim of this study was to examine the extent of racial/ethnic disparities in the provision of pharmacotherapy, cholesterol screening and diet/nutrition or exercise counseling during US office-based physician-patient encounters (visits) by patients with hyperlipidemia. METHODS: We examined data from the 2005 US National Ambulatory Medical Care Survey for office-based visits for hyperlipidemia for patients aged > or =20 years in terms of prescribing for hyperlipidemia, and the ordering/provision of cholesterol testing, diet/nutrition counseling, and exercise counseling. RESULTS: Use of pharmacotherapy for hyperlipidemia varied by ethnicity/race (chi2, p < 0.05). Physician-ordered/provided cholesterol screening occurred in 44.2% of all office-based visits; 46.5% for Whites, 35.4% for Blacks, and 30.3% for Hispanics (chi2, p < 0.05). Diet/nutrition counseling was ordered/provided in 39.7% of office-based visits; 40.4% for Whites, 32.6% for Blacks, and 39.0% for Hispanics (chi2, p < 0.05). Exercise counseling was ordered/provided in 32.1% of office-based visits; 32.7% for Whites, 27.2% for Blacks, and 30.6% for Hispanics (chi2, p < 0.05). CONCLUSIONS: These findings reveal a disparity in use of pharmacotherapy for hyperlipidemia, physician-ordered/provided cholesterol screening, diet/nutrition counseling, and exercise counseling by ethnicity/race. Further research is required to discern, in greater detail, reasons for the observed differences reported, and to ensure equitable access to established standards of care.

Transdermal opioids for cancer pain.

Patients with moderate to severe malignancy-related pain frequently require the use of opioid pharmacotherapy. Unfortunately, many cancer patients continue to be prescribed subtherapeutic doses of pain medications resulting in undo suffering and diminished quality of life. The choice of analgesic pharmacotherapy should be individualized and based on the intensity and etiology of pain reported by the patient. Health care providers must be able to readily quantify the relative analgesic potency when converting from one opioid to another or from one route of administration to another. Transdermal fentanyl is effective and well tolerated pharmacotherapy for the cancer pain patients. However, clinicians need to be cognizant that the U.S./U.K. manufacturer's recommendations for equilalagesic dosing of transdermal fentanyl may result in initial doses that produce subtherapeutic levels and unrelieved pain in some patients. A more aggressive dosing algorithm for transdermal fentanyl using a 2:1 (mg/day of oral morphine: mcg/hr of transdermal fentanyl) conversion ratio that considers both a review of the literature and clinical experience should help clinicians individualize cancer pain pharmacotherapy. Transdermal buprenorphine is now being prescribed in Europe and Australia for chronic and cancer pain management. Buprenorphine's mixed agonist/antagonist activity, dosage ceiling, and high affinity to the opiate receptor limits its use to those patients who do not already require large daily doses of opioids. Thus, buprenorphine may not be an appropriate medication for some patients with advanced unremitting cancer pain.

Practice guidelines for transdermal opioids in malignant pain.

Patients with moderate-to-severe malignancy-related pain require opioid pharmacotherapy. Many cancer patients continue to be prescribed subtherapeutic doses of pain medications resulting in undue suffering and diminished quality of life. Pain associated with malignancy and its treatment may exacerbate other symptoms associated with cancer, including nausea, fatigue, weakness, dyspnoea, constipation and impaired cognition. The choice of analgesic pharmacotherapy should be individualised and based on the intensity of pain reported by the patient, rather than its specific aetiology. When selecting pain management pharmacotherapy, the healthcare provider should consider the patient's pain level, activity level and any comorbid illness. Intolerable adverse effects, ineffective pain relief or a change in the patient's clinical status can dictate the need for a new pain management regimen. Healthcare providers must be able to readily quantify the relative analgesic potency when converting from one opioid to another or from one route of administration to another. Transdermal formulations of fentanyl and buprenorphine are effective pharmacotherapy that can be safely used for cancer patients with pain. However, clinicians need to be cognisant that the US/UK manufacturer's recommendations for equianalgesic dose administration of transdermal fentanyl may result in initial doses that produce subtherapeutic concentrations and unrelieved pain in some patients. A less conservative dose administration algorithm for transdermal fentanyl using a 2:1 (mg/day of oral morphine : microg/h of transdermal fentanyl) conversion ratio that considers both a review of the literature and clinical experience should help clinicians individualise cancer pain pharmacotherapy.
