Use of electronic health record data to examine administrations of pro re nata analgesics during hip fracture post-acute care.

PURPOSE: Medications prescribed to older adults in US skilled nursing facilities (SNF) and administrations of pro re nata (PRN) "as needed" medications are unobservable in Medicare insurance claims. There is an ongoing deficit in our understanding of medication use during post-acute care. Using SNF electronic health record (EHR) datasets, including medication orders and barcode medication administration records, we described patterns of PRN analgesic prescribing and administrations among SNF residents with hip fracture. METHODS: Eligible participants resided in SNFs owned by 11 chains, had a diagnosis of hip fracture between January 1, 2018 to August 2, 2021, and received at least one administration of an analgesic medication in the 100 days after the hip fracture. We described the scheduling of analgesics, the proportion of available PRN doses administered, and the proportion of days with at least one PRN analgesic administration. RESULTS: Among 24 038 residents, 57.3% had orders for PRN acetaminophen, 67.4% PRN opioids, 4.2% PRN non-steroidal anti-inflammatory drugs, and 18.6% PRN combination products. The median proportion of available PRN doses administered per drug was 3%-50% and the median proportion of days where one or more doses of an ordered PRN analgesic was administered was 25%-75%. Results differed by analgesic class and the number of administrations ordered per day. CONCLUSIONS: EHRs can be leveraged to ascertain precise analgesic exposures during SNF stays. Future pharmacoepidemiology studies should consider linking SNF EHRs to insurance claims to construct a longitudinal history of medication use and healthcare utilization prior to and during episodes of SNF care.

Syzygium cumini (L.) Skeels extracts; in vivo anti-nociceptive, anti-inflammatory, acute and subacute toxicity assessment.

ETHNOPHARMACOLOGICAL RELEVANCE: Syzygium cumini (L.) Skeels has been extensively used in the ancient medical system of Pakistan, India, Bangladesh, and Sri Lanka to combat diabetes, inflammation, and renal disorders. These health-promoting aspects of S. cumini are related to bioactive metabolites such as phenolic acids, anthocyanins, tannins, and flavonoids. AIM OF THE STUDY: Earlier to this study, we have reported S. cumini extracts as potential sources of bioactive compounds bearing antioxidant and anti-inflammatory properties. However, prior further suggesting S. cumini fruit extracts for consumption against inflammatory disorders, it was mandatory to validate the claim and explore toxicity of the extracts. This study aims to determine the in vivo anti-nociceptive, anti-inflammatory, acute, and subacute toxicity properties of S. cumini crude extracts, followed by identifying and quantifying bioactive metabolites. MATERIAL AND METHODS: In the present study, the anti-nociceptive and anti-inflammatory potential of S. cumini sequential crude extracts were evaluated using formalin and glutamate-induced paw licking method in mice. The acute and sub-acute toxicity assessment of active extract was performed by oral administration in rats. An acute toxicity trial was performed with two different doses, i.e., 2000 mg/kg and 3000 mg/kg for consecutive 14 days, whereas a sub-acute toxicity study was conducted at doses of 750 mg/kg and 1500 mg/kg for the next 28 days. Identification of bioactive compounds was performed using HPLC, and at the end, in silico docking calculations of identified compounds were performed. RESULTS: The 100% methanolic extract (SCME) protected the mice from painful stimulation of formalin and glutamate in a dose-dependent manner with the maximum effect of 49% and 67% at 200 mg/kg, respectively, followed by moderate and non-influential effects of 50% methanolic extract and dichloromethane (DCM) extracts when compared to control, i.e., normal saline. The results of acute toxicity recorded LD50 of SCME over 3000 mg/kg, and no antagonistic effects were recorded during the subacute study when SCME dispensed at the rate of 750 mg/kg and 1500 mg/kg. SCME was found to induce no adverse effects to kidney, heart, liver, spleen, and paired lungs examined by hematological, serum biochemical, histological analysis. HPLC analysis of S. cumini 100% methanolic extracts revealed the presence of delphinidin 3-glucoside, peonidin-3,5-diglucoside, scopoletin, and umbelliferone at the concentration of 127.4, 2104, 31.3, 10.4 µg/g whereas in 50% methanolic extract, the quinic acid, catechin, and myricetin were present at the concentration of 54.9, 63.7, 12.3 µg/g, respectively. Umbelliferone and scopoletin are newly reported compounds in the present study. In silico docking calculations of these compounds indicated the potential of anti-nociceptive and anti-inflammatory activities. CONCLUSIONS: These findings validate that S. cumini fruit extracts are a rich source of bioactive compounds that needs to be considered to enhance biological activities with lesser side effects.

A Call to Action by the Italian Mesotherapy Society on Scientific Research.

Mesotherapy (local intradermal therapy, LIT) is a technique used to slowly spread drugs in tissues underlying the site of injection to prolong the pharmacological effect with respect to intramuscular injection. Recommendations for proper medical use of this technique have been made for pain medicine and rehabilitation, chronic venous disease, sport medicine, musculoskeletal disorders, several dermatological conditions, skin ageing, and immune-prophylaxis. Although mesotherapy is considered a valid technique, unresolved questions remain, which should be answered to standardize methodology and dosing regimen as well as to define the right indications in clinical practice. New randomized controlled trials are needed to test single products (dose, frequency of administration, efficacy and safety). Even infiltration of substances for dermo-cosmetic purposes must be guided by safety and efficacy tests before being proposed by mesotherapy. In this article, we put forth a preclinical and clinical research plan and a health technology assessment as a call to action by doctors, researchers and scientific societies to aid national health authorities in considering mesotherapy for prevention, treatment and rehabilitation paths.

Efficacy of a pediatric headache infusion center: A single-center experience.

OBJECTIVE: To evaluate the efficacy of a pediatric headache infusion center (HIC) in alleviating the symptoms and preventing future visits to the emergency department (ED). BACKGROUND: Headache is a common reason for visits to the pediatric ED. ED visits are associated with inordinate costs of care and are conceived by parents to be avoidable if adequate alternatives are available. An infusion center for acute treatment of intractable headache in children with chronic migraine may be an effective alternative to an ED visit. METHODS: This was a retrospective analysis of data from a single-center cohort of patients with a known history of chronic migraine, presenting to Dayton Children's HIC with an acute migraine from June 1, 2017 to June 1, 2020. Patients were treated according to established protocols divided into two pathways. Patient demographics, clinical characteristics, pre- and postinfusion pain scores, ED visits and inpatient admissions within 2 weeks of HIC visit, and ED visits 1 year prior and 1 year after the HIC visit were noted. RESULTS: A total of 297 HIC visits were analyzed from 201 patients. The HIC was effective in controlling symptoms with a significant reduction in pain score (median [interquartile range; IQR] 7.0 [2.0] preinfusion vs. 1.0 [2.0] postinfusion, p < 0.001). Only 25/297 (8.4%) patients came to the ED within 2 weeks of the HIC visit, and an even smaller number of patients (20/297, 6.7%) were admitted as inpatients within 2 weeks of the HIC visit. The number of ED visits was significantly reduced in the year after the HIC visit compared with the year prior (median [IQR] 1.0 [2.0] before vs. 0.0 [1.0] after, p < 0.001). CONCLUSION: A pediatric HIC is effective in alleviating the symptoms and preventing ED visits. These centers should be considered as standard of care at children's hospitals.

Association Between Dual Trajectories of Opioid and Gabapentinoid Use and Healthcare Expenditures Among US Medicare Beneficiaries.

OBJECTIVES: Little is known about relationships between opioid- and gabapentinoid-use patterns and healthcare expenditures that may be affected by pain management and risk of adverse outcomes. This study examined the association between patients' opioid and gabapentinoid prescription filling/refilling trajectories and direct medical expenditures in US Medicare. METHODS: This cross-sectional study included a 5% national sample (2011-2016) of fee-for-service beneficiaries with fibromyalgia, low back pain, neuropathy, or osteoarthritis newly initiating opioids or gabapentinoids. Using group-based multitrajectory modeling, this study identified patients' distinct opioid and gabapentinoid (OPI-GABA) dose and duration patterns, based on standardized daily doses, within a year of initiating opioids and/or gabapentinoids. Concurrent direct medical expenditures within the same year were estimated using inverse probability of treatment weighted multivariable generalized linear regression, adjusting for sociodemographic and health status factors. RESULTS: Among 67 827 eligible beneficiaries (mean age ± SD = 63.6 ± 14.8 years, female = 65.8%, white = 77.1%), 11 distinct trajectories were identified (3 opioid-only, 4 gabapentinoid-only, and 4 concurrent OPI-GABA trajectories). Compared with opioid-only early discontinuers ($13 830, 95% confidence interval = $13 643-14 019), gabapentinoid-only early discontinuers and consistent low-dose and moderate-dose gabapentinoid-only users were associated with 11% to 23% lower health expenditures (adjusted mean expenditure = $10 607-$11 713). Consistent low-dose opioid-only users, consistent high-dose opioid-only users, consistent low-dose OPI-GABA users, consistent low-dose opioid and high-dose gabapentinoid users, and consistent high-dose opioid and moderate-dose gabapentinoid users were associated with 14% to 106% higher healthcare expenditures (adjusted mean expenditure = $15 721-$28 464). CONCLUSIONS: Dose and duration patterns of concurrent OPI-GABA varied substantially among fee-for-service Medicare beneficiaries. Consistent opioid-only users and all concurrent OPI-GABA users were associated with higher healthcare expenditures compared to opioid-only discontinuers.

Disease burden on health care by pain severity and usual analgesic treatment in patients with symptomatic osteoarthritis: a Spanish nationwide health survey.

BACKGROUND: Osteoarthritis (OA) pain is a health care highly demanding and costing condition. OBJECTIVE: To estimate disease burden on health care in OA in Spain, determining whether burden differs by pain severity and usual analgesic treatment. METHODS: A cross-sectional design using the 2017-Spanish-National-Health-Survey was used to abstract data of 5,234 adult patients (women 70.8%; 69.9 years) with a self-reported physician OA diagnosis. Patients were assembled according to pain severity (no/mild, moderate, severe) and use of usual analgesia (treated [66.5%]/untreated). Healthcare resource utilization (HRU) and corresponding costs were expressed Per-Patient-Per-Year (PPPY) and adjusted for covariates. RESULTS: Average (SD) healthcare cost was €2,274 (5,461) PPPY, with costs linked to outpatient medical visits being the major driver; ~43%. Adjusted PPPY medical visits, days of hospitalization, other healthcare visits, and corresponding costs were significantly higher in severe pain OA patients, compared to moderate or mild/no pain regardless of being currently treated with usual analgesics or not (p < 0.001). Treated OA patients showed higher HRU and costs than untreated patients. CONCLUSIONS: Severity of pain was the main driver of HRU and costs in OA patients from a nationwide representative survey in Spain. These findings seem to be more consistent in treated versus not treated patients with usual analgesics.

The Unmet Need for Intrathecal Drug Delivery Pumps for the Treatment of Cancer Pain in England: An Assessment of the Hospital Episode Statistics Database.

OBJECTIVES: Intrathecal drug delivery (ITDD) devices have been shown to be a clinically effective and cost-effective option for the management of cancer pain and recommended for use in England. The aim of this study is to assess the impact of the 2015 NHS England Clinical Commissioning Policy on the uptake of ITDD pumps for the management of cancer pain or if there is an ongoing unmet need for this intervention in England. MATERIALS AND METHODS: Hospital Episode Statistics (HES) were obtained for all patients undergoing ITDD for the management of cancer pain between 2014 and January 2020. In addition, HES were utilized to estimate the number of patients with cancer potentially eligible for ITDD pump during the same period. RESULTS: The number of patients with cancer and those potentially suitable to receive an ITDD for the management of cancer pain have increased year on year since 2014. This increase has not been matched by an uptake in the provision of ITDD. Conservative estimates suggest that at least 8000 people with cancer pain would be eligible for ITDD; 458 patients received an intervention for pain management between April 2018 and March 2019 and only 30 ITDD pumps were implanted in that same period. CONCLUSIONS: We observed a substantial gap between the need and provision of ITDD for patients with refractory cancer pain in England despite the recommendation for the use of ITDD for this patient population. In addition, we present suggestions for improvement of access to and provision of ITDD in England.

Chronic pain and substance abuse disorders: Preoperative assessment and optimization strategies.

There is an ever-increasing number of opioid users among chronic pain patients and safely managing them can be challenging for surgeons, anesthesiologists, pain experts, and addiction specialists. Healthcare providers must be familiar with phenomena typical of opioid users and abusers, including tolerance, physical dependence, hyperalgesia, and addiction. Insufficient pain management is very common in these patients. Patient-centered preoperative communication is integral to setting realistic expectations for postoperative pain, developing successful nonopioid analgesic regimens, minimizing opioid consumption during the postoperative period, and decreasing the number of opioid pills at the risk of diversion. Preoperative evaluation should identify comorbidities and identify risk factors for substance abuse and withdrawal. Intraoperative and postoperative strategies can ensure safe and effective pain management and minimize the potential for morbidity and mortality in this high-risk patient population.

COVID-19 et pénurie de sédatifs, analgésiques et bloqueurs neuromusculaires: alternatives et principes de sédation aux soins intensifs et au bloc opératoire / COVID-19 and shortage of sedatives, pain relievers and blockers neuromuscular: alternatives and principles of sedation to care intensive and in the operating room

CONTEXTE: Le présent document ainsi que les constats qu'il énonce ont été rédigés en réponse à une interpellation du ministère de la Santé et des Services sociaux dans le contexte de l'urgence sanitaire liée à la maladie à coronavirus (COVID-19) au Québec. L'objectif est de réaliser une recension sommaire des données publiées et de mobiliser les savoirs clés afin d'informer les décideurs publics et les professionnels de la santé et des services sociaux. Vu la nature rapide de cette réponse, les constats ou les positions qui en découlent ne reposent pas sur un repérage exhaustif des données publiées, une évaluation de la qualité méthodologique des études avec une méthode systématique ou sur un processus de consultation élaboré. Dans les circonstances d'une telle urgence de santé publique, l'INESSS reste à l'affût de toutes nouvelles données susceptibles de lui faire modifier cette réponse rapide. PRÉSENTATION DE LA DEMANDE: La COVID-19 peut entraîner certaines complications graves qui nécessitent l'hospitalisation de la personne affectée, notamment le syndrome de détresse respiratoire aigu (ARDS) qui nécessite la mise en place d'une ventilation mécanique. Parmi les médicaments administrés dans le cadre d'une ventilation mécanique se trouve entre autres le propofol, un agent sédatif-hypnotique utilisé pour diminuer l'inconfort d'une intubation aux soins intensifs, ainsi que le rocuronium et le cistracurium, des bloqueurs neuromusculaires non dépolarisants qui permettent, dans certains cas, d'améliorer la synchronisation de la ventilation mécanique. Plusieurs de ces médicaments sont également employés au bloc opératoire, aux urgences, dans les unités de soins palliatifs ainsi que dans le contexte de l'aide médicale à mourir, ce qui crée une compétition entre les différents secteurs cliniques pour l'accès à ces molécules. La pandémie actuelle liée à la COVID-19 exerce une pression mondiale énorme sur les stocks de médicaments utilisés aux soins intensifs. À titre d'exemple, aux États-Unis, la demande pour les sédatifs les plus couramment utilisés aux soins intensifs et au bloc opératoire (propofol, dexmédétomidine, étomidate, kétamine, lorazépam, midazolam) a augmenté de 51 % durant le mois dernier [Phend, 2020]. Neuf grands centres hospitaliers européens ont annoncé, le 2 avril dernier, ne disposer que de 2 semaines de réserves de médicaments essentiels pour les soins critiques [Cheng, 2020]. Au Québec, le propofol est d'ailleurs en situation de rupture de stock jusqu'à la mi-avril auprès de son fabricant, la compagnie Baxter. Afin d'être en mesure de poursuivre la mise en place de la ventilation mécanique auprès des personnes qui le nécessitent, et ce, même en cas de pénurie de propofol, de cisatracurium ou de rocuronium, le MSSS a demandé à l'INESSS d'identifier les médicaments qui pourraient constituer des options alternatives à ces molécules aux soins intensifs et au bloc opératoire, tout en tenant compte des ruptures de stock actuelles et anticipées.

Deriving harmonised permitted daily exposures (PDEs) for paracetamol (acetaminophen) CAS #: 103-90-2.

In the pharmaceutical industry, cleaning criteria are required for multipurpose manufacturing facilities. These Health Based Exposure Limits (HBELs), also called permitted daily exposures (PDEs) values, are derived from toxicological and pharmacological evaluation of the active pharmaceutical ingredients (APIs). The purpose of this publication is to show an example of how authors from different companies evaluate a generic drug, paracetamol, and discuss different approaches and relevance of the nonclinical studies for deriving PDEs. PDE limits of 25 mg/day for the oral route, and 20 mg/day for the intravenous (i.v.) and inhalation (inhal.) routes, respectively, were established herein. However, it has been already recognised that there are acceptable differences in the PDE calculations, which may be based on data accessibility, company-specific science-policy decisions or expert judgments. These differences can cause up to a 3-fold lower or higher values. If unnecessarily high factors are applied, this would result in a very conservative PDE value and unneeded additional cleaning and higher manufacturing costs. The PDE values presented are considered to be protective against adverse and pharmacological effects observed in clinical trials and in this case, a very long postmarketing period of paracetamol.

Capsaicin 8% dermal patch in clinical practice: an expert opinion.

INTRODUCTION: Neuropathic pain (NP) is caused by a lesion or disease of the somatosensory system, which can severely impact patients' quality of life. The current-approved treatments for NP comprise of both centrally acting agents and topical drugs, including capsaicin 8% dermal patches, which is approved for the treatment of peripheral NP. AREAS COVERED: The authors summarize literature data regarding capsaicin use in patients who suffer from NP and discuss the clinical applications of this topical approach. EXPERT OPINION: Overall, the capsaicin 8% dermal patch is as effective in reducing pain intensity as other centrally active agents (i.e. pregabalin). Some studies have also reported fewer systemic side effects, a faster onset of action and superior treatment satisfaction compared with systemic agents. In our opinion, capsaicin 8% dermal patches also present additional advantages, such as a good systemic tolerability, the scarcity of adverse events, the possibility to combine it with other agents, and a good cost-effective profile. It is important to note that, as the mechanism of action of capsaicin 8% is the 'defunctionalization' of small afferent fibers through interaction with TRPV1 receptors, the peripheral expression of this receptor on nociceptor fibers, is crucial to predict patient's response to treatment.

Role of Micro-RNA for Pain After Surgery: Narrative Review of Animal and Human Studies.

One of the most prevalent symptoms after major surgery is pain. When postoperative pain treatment is unsatisfactory, it can lead to poor surgical recovery, decreased quality of life, and increased health care costs. Current analgesics, single or in combination, have limited efficacy due to low potency, limited duration of action, toxicities, and risk of addiction. The lack of nonaddictive strong analgesics along with the over prescription of opioids has led to an opioid epidemic in the United States. Therefore, there is an urgent need for the development of newer analgesics. Microribonucleic acids (miRNAs) are small noncoding RNA molecules that modulate protein synthesis in neurons and supporting cells (glia, leukocytes, and Schwann cells). The literature indicates that miRNA regulation is important in nociception. Here, we summarize the current evidence on the role of miRNAs on mechanisms involved in incisional, inflammatory, neuropathic, and cancer pain. We also discuss the role of modulating miRNA functions as potential therapeutic targets for analgesic use and opioid tolerance. Finally, we propose how the delivery of analog miRNAs (mimic-miRNAs or antago-miRNAs) could be introduced into clinical practice to provide analgesia in the perioperative period.

Prevalence, attitude and practice of self-medication among adolescents and the paradigm of dysmenorrhea self-care management in different countries.

Self-medication (SM) is an important worldwide public health issue affecting children and adolescents. The pattern of SM varies in different communities, affected by factors such as age, sex, income, expense, self-care orientation, educational level and medical knowledge. It is a fairly common practice: for minor health problems, it often provides cheap, rapid, and convenient solutions, outside of the health care system of many countries. Painkillers, antipyretics, cough medicines, cold preparations, dermatological products, nutritional supplements and antibiotics are the drugs most frequently used. Potential risks include incorrect self-diagnosis, improper dosage, inappropriate choice of therapy, masking of severe disease and drug interactions. Lack of awareness of warnings and precautions, storage conditions, the recommended shelf-life and adverse reactions increase the risk of side effects. Little is known about the SM of dysmenorrhea by adolescent girls. Attitudes towards treatment are influenced by cultural, ethnic, and religious factors. Some girls discuss dysmenorrhea with family and friends, and the majority may not seek medical advice. As dysmenorrhea is a common problem for adolescents, it is essential that these girls be aware of the normal and abnormal symptoms of menstruation. In the light of these findings, the roles of family, school, health professionals and health authorities are of utmost importance for the implementation of measures to approach this health problem in a more efficient way.

Nitrous Oxide versus Medical Air Using in General Anaesthesia During Laparoscopic Cholecystectomy: A Comparative Study.

This study was designed to observe the haemodynamic changes, recovery status and cost effectiveness during anaesthesia in laparoscopic cholecystectomy with medical air in comparison to anaesthesia with nitrous oxide associated with maintain of adequate analgesia and was conducted in the department of Analgesia and Intensive Care Medicine, Bangabandhu Sheikh Mujib Medical University (BSMMU), Dhaka, Bangladesh from January 2017 to June 2017. Nitrous oxide is popularly using as an analgesic in current balanced general anesthesia in addition carrier agent for anesthetic. Intraoperative pain intensity depends on many variables including, type of surgery, surgical stimulation and surgical incision. It is difficult to measure intraoperative pain properly under general anesthesia therefore anesthetist depends on the surrogate marker of inadequate analgesia like raised heart rate, blood pressure, sweating and lacrimation. However, unfortunately, these parameters may changes in same direction with light plane of anesthesia, hypercarbia and ongoing procedural status of the patient.

2019 American College of Rheumatology/Arthritis Foundation Guideline for the Management of Osteoarthritis of the Hand, Hip, and Knee.

OBJECTIVE: To develop an evidence-based guideline for the comprehensive management of osteoarthritis (OA) as a collaboration between the American College of Rheumatology (ACR) and the Arthritis Foundation, updating the 2012 ACR recommendations for the management of hand, hip, and knee OA. METHODS: We identified clinically relevant population, intervention, comparator, outcomes questions and critical outcomes in OA. A Literature Review Team performed a systematic literature review to summarize evidence supporting the benefits and harms of available educational, behavioral, psychosocial, physical, mind-body, and pharmacologic therapies for OA. Grading of Recommendations Assessment, Development and Evaluation methodology was used to rate the quality of the evidence. A Voting Panel, including rheumatologists, an internist, physical and occupational therapists, and patients, achieved consensus on the recommendations. RESULTS: Based on the available evidence, either strong or conditional recommendations were made for or against the approaches evaluated. Strong recommendations were made for exercise, weight loss in patients with knee and/or hip OA who are overweight or obese, self-efficacy and self-management programs, tai chi, cane use, hand orthoses for first carpometacarpal (CMC) joint OA, tibiofemoral bracing for tibiofemoral knee OA, topical nonsteroidal antiinflammatory drugs (NSAIDs) for knee OA, oral NSAIDs, and intraarticular glucocorticoid injections for knee OA. Conditional recommendations were made for balance exercises, yoga, cognitive behavioral therapy, kinesiotaping for first CMC OA, orthoses for hand joints other than the first CMC joint, patellofemoral bracing for patellofemoral knee OA, acupuncture, thermal modalities, radiofrequency ablation for knee OA, topical NSAIDs, intraarticular steroid injections and chondroitin sulfate for hand OA, topical capsaicin for knee OA, acetaminophen, duloxetine, and tramadol. CONCLUSION: This guideline provides direction for clinicians and patients making treatment decisions for the management of OA. Clinicians and patients should engage in shared decision-making that accounts for patients' values, preferences, and comorbidities. These recommendations should not be used to limit or deny access to therapies.

Rapid recovery following hip and knee arthroplasty using local infiltration analgesia: length of stay, rehabilitation protocol and cost savings.

BACKGROUND: We implemented local infiltration analgesia (LIA) as a technique of providing post-operative pain management and early mobilization after arthroplasty surgery and have progressively found patients able to go home earlier. This study compares the national data on hip and knee arthroplasty provided by the Royal Australasian College of Surgeons and Medibank Private with our outcomes using LIA and rapid recovery. METHODS: Prospective study of one surgeon including 200 knees, and 165 hips in the two years till June 2016. Variables included in comparison to the two groups were: length of stay, percentage of patients transferred to rehabilitation or intensive care unit (ICU), readmitted within 30 days and average separation cost. RESULTS: Hip replacement median length of stay in our series was two nights versus five nights, inpatient rehabilitation 7% versus 36%, ICU admission zero versus 4%, and readmissions 3.9% versus 6.0%, the average hospital separation cost in our series was $17 813 versus $26 734. Knee replacement median length of stay in our study was one night versus five nights, ICU 0.5% versus 3%, rehabilitation 4.5% versus 43%, and readmission 6% versus 7%, the average hospital separation cost in our group was $16 437 versus $27 505. CONCLUSION: The comprehensive approach of LIA and rapid recovery enables patients to have shorter hospitalization, lower rehabilitation incidence and a resultant reduction in health expenditure.

Pain Intensity: How Press Ganey Survey Domains Correlate in Total Knee Arthroplasty Patients.

Decreasing postoperative pain for total knee arthroplasty (TKA) patients has been an area of continued effort for healthcare providers. These efforts have been incentivized by legislative reform, which ties reimbursement for hospitals and providers to patient perception of care. Press Ganey (PG) surveys quantify patient satisfaction, and the "pain management" domain is thought to be the best metric for assessing pain intensity. Therefore, these responses are important, as they are used to guide further improvements in healthcare delivery. This study analyzes which PG survey domains are truly associated with pain intensity in the immediate postoperative period following TKA. We queried our PG database for all primary TKA patients between November 2012 and January 2015, yielding a total of 214 patients. Multivariate regression analysis was performed utilizing pain intensity as the dependent variable. Predictor variables included body mass index (BMI), Charlson's comorbidity index, opioid consumption, and PG survey domains. Patient ratings of "communication with doctors" (B = 58.147; p = 0.001), "responsiveness of hospital staff" (B = - 62.663; p = 0.041), "communication about medicines" (B= -45.037; p < 0.001), and "hospital environment" (B = 69.342; p = 0.017) were associated with patient pain intensity. We found survey domains, other than "pain management," were associated with pain intensity. Efforts to improve outcomes and satisfaction should focus on staff education and communication. The current method for measuring patient satisfaction and reimbursement should be critically assessed and redesigned to better reflect true patient experiences.

Chemotherapy-induced peripheral neuropathy (CIPN) and its treatment: an NIH Collaboratory study of claims data.

PURPOSE: Chemotherapy-induced peripheral neuropathy (CIPN) is a disabling complication of many chemotherapies. We investigated the feasibility of using health plan claims and administrative data to identify CIPN occurrence by comparing patients who received neurotoxic and non-neurotoxic chemotherapies. METHODS: The sample included over 53,000,000 patients from two regional and one national insurer in the USA (> 400,000 exposed to chemotherapy). Peripheral neuropathy was identified using a broad definition (definition 1) and a specific definition (i.e., drug-induced polyneuropathy code) (definition 2). RESULTS: CIPN incidence as measured by definition 1 within 6 months of chemotherapy initiation was 18.1% and 6.2% for patients who received neurotoxic and non-neurotoxic chemotherapy, respectively (relative risk neurotoxic vs. non-neurotoxic (RR), 2.93 (95% CI, 2.87-2.98)). For definition 2, these incidences were 3.6% and 0.1% (RR, 25.2 (95% CI, 22.8-27.8)). The incidences of new analgesic prescriptions for neurotoxic and non-neurotoxic groups were as follows: gabapentin, 7.1%/1.7%; pregabalin, 0.69%/0.31%; and duloxetine, 0.78%/0.76%. The incidence of CIPN as defined by definitions 1 and 2 was low compared with that of published research studies, but the relative risk of CIPN among patients who received neurotoxic chemotherapies compared with those who received non-neurotoxic chemotherapies was high using definition 2. CONCLUSIONS: These data suggest that as used currently by clinicians, administrative codes likely underestimate CIPN incidence. Thus, studies using administrative data to estimate CIPN incidence are not currently feasible. However, the drug-induced polyneuropathy code is a specific indicator of CIPN in administrative data and may be useful for investigating predictors or potentially preventive therapies of CIPN.

Self-medication practice in Akuse, a rural setting in Ghana.

OBJECTIVE: In most resource-poor settings, there is a paucity of data on self-medication and possible factors that influence this practice. The current study assesses self-medication among the people of Akuse, a rural setting in the Eastern Region of Ghana. METHODS: A quantitative cross-sectional study was carried out in Akuse from 4th January 2016 to 27th February 2016. Using a questionnaire, interviews were conducted to assess self-medication: class of drugs taken, sources of drugs, knowledge of potential adverse effects, among others. RESULTS: Of the 363 participants enrolled, 361 completed questionnaires administered. Of the 361 respondents, 58.4% were female. A majority of the respondents were within the ages of 30 and 45 years. Respondents were mainly farmers (40.2%), and a majority (44.6%) had primary level as the highest education. One major reason for self-medication was influence from family and friends (32.7%). Antibiotics (32.1%) and analgesics (21.0%) were the most common self-medicated drugs, and these drugs were mostly obtained from licenced chemical sellers (32.5%). A little more than a third (39.9%) of the respondents said that their condition did not change after self-medication. A greater number of the respondents (81.7%) did not have knowledge of potential adverse reactions associated with self-medicated drugs. However, respondents with high educational level had the most knowledge of adverse drug reactions. CONCLUSION: The study found self-medication as a common practice among a number of residents of Akuse. Findings from this study provide data that could be used for targeted education and sensitisation of self-medication and its demerits in similar resource-poor rural settings.
