Psychotic-like experiences with cannabis use predict cannabis cessation and desire to quit: a cannabis discontinuation hypothesis.

BACKGROUND: Evidence suggests that cannabis-induced psychotic-like experiences may be a marker of psychosis proneness. The effect of such experiences on cannabis use has not systematically been examined. METHODS: We undertook a mixed-methods online survey of 1231 cannabis users (including 926 continued users) using the Cannabis Experiences Questionnaire. We examined the effect of psychotic-like and pleasurable experiences on cessation of cannabis and intention to quit. Socio-demographic variables, cannabis use parameters and substance misuse history were included as covariates. Free-text data explored subjective reasons for changes in use. RESULTS: Cessation of cannabis use was associated with greater psychotic-like experiences [p < 0.001, Exp(B) 1.262, 95% confidence interval (CI) 1.179-1.351], whilst continued cannabis users were more likely to report pleasurable experiences [p < 0.001, Exp(B) 0.717, 95% CI 0.662-0.776]. Intention to quit cannabis in continued users was associated with greater psychotic-like experiences [p < 0.003, Exp(B) 1.131, 95% CI 1.044-1.225], whilst intention to not quit was significantly associated with increased pleasurable experiences [p < 0.015, Exp(B) 0.892, 95% CI 0.814-0.978]. Whereas former users clearly ascribed cessation to negative experiences, continued users who expressed intention to quit less readily ascribed the intention to negative experiences. CONCLUSIONS: Elucidation of psychotic-like experiences may form the basis of a therapeutic intervention for those who wish to quit. Cessation in those with cannabis-induced psychotomimetic experiences may offset the risk for the development of a psychotic disorder, in this higher risk group.

Use of smartphone and perception towards the usefulness and practicality of its medical applications among healthcare workers in Saudi Arabia.

BACKGROUND: In Saudi Arabia, healthcare industry is undergoing major expansions to meet the demand of rapidly growing healthcare needs. The aims of this study were; (1) to assess the pattern of smartphone use in healthcare facilities, and (2) to determine perception towards its use among healthcare workers. METHOD: A cross-sectional survey of 351 healthcare workers (HCWs) at King Abdulaziz Medical City (KAMC) in Riyadh, Saudi Arabia was conducted, from October to November 2016, using a previously validated perception domain to measure perception towards usefulness (5 statements) and practicality (5 statements) of smartphones in clinical settings. Pattern of use of smartphones and health-related applications in healthcare facilities was also investigated. Logestic regression models were applied to identify the predictors of smartphone use and installation of health-related applications for use in healthcare facilities. Significance was considered at p-value of < 0.05. RESULTS: Utilization rate of smartphone was 42.3%, and only 6.1% of all healthcare providers reported always using applications in their practice. Reasons for use were: as a source of drug information (69.8%), for disease diagnosis (56.4%), to access medical websites (42.5%), to review guidelines and protocols related to healthcare (34.1%), for procedure documentation (23.5%), and as a source of patients education materials (22.3%). Perceptions of HCWs towards smartphone use was less than satisfactory (Overall percentage mean score = 60.4 ± 18.7), with only 11.6% reporting positive perception. After adjusting for possible confounders, the total perception mean score was a significant predictor of both smartphone use (ß = 0.033, p < 0.001) and medical applications installation (ß = 0.033, p < 0.001). Installation of medical applications was also predicted by being a physician (ß = 0.008, p = 0.024). CONCLUSION: Smartphone utilization in healthcare facilities by HCWs in Saudi Arabia is low. This could be attributed to their less than satisfactory level of perception towards its use. Smartphone use and installation of medical applications for use in health facilities were predicted by perceived usefulness and practicality of its use. Intervention from higher health authorities is necessary to enforce the importance of smartphone use in clinical practice. Conduction of further studies on the impact of smart phone use on the healthcare quality in Saudi Arabia is recommended.

Prescribing pattern and resource utilization of monoamine oxidase-B inhibitors in Parkinson treatment: comparison between rasagiline and selegiline.

Difference between selegiline and rasagiline for effectiveness in Parkinson's disease (PD) is uncertain, nevertheless their costs highly differ: rasagiline is more expensive than selegiline. This study was aimed to compare prescribing pattern and resource utilization in PD patients treated with rasagiline or selegiline. Historic cohort study, based on databases of three Italian Local Health Authorities was performed. Patients with PD and receiving rasagiline or selegiline between 01-07-2009 and 31-12-2011 were selected and followed-up for 12 months. As outcomes, and relevant costs, were evaluated: (a) anti-parkinson prescriptions; (b) hospitalization for PD and for fracture; (c) antiinflammatory and antirheumatic prescriptions; (d) antipsychotic prescriptions; (e) hospitalization for cardiovascular diseases; (f) cardiovascular prescriptions; (g) ambulatory visits or diagnostic tests. Average annual cost per patient was considered for both PD-related expenditure (a + b + c) and overall cost (a + b + c + d + e + f + g). Differences between rasagiline and selegiline were analysed by generalized linear model. Overall 1607 patients were selected: 63.7 % under selegiline and 36.2 % under rasagiline. Hospitalizations for PD occurred more in rasagiline group than in selegiline one (13.6 vs. 8.0 %, p < 0.001), whereas hospitalizations for fractures less in rasagiline group than in selegiline one (1.4 vs. 3.8 %, p = 0.005). Dopamine agonists (66.0 vs. 31.0 %, p < 0.001) and levodopa (73.9 vs. 49.0 %, p < 0.001) were prescribed more frequently in rasagiline group than in selegiline one. The choice to prescribe rasagiline produced a statistically significant increase in both overall cost (+2404 €, p < 0.001) and PD-related cost (+2363 €, p < 0.001). In conclusion, prescribing patterns and health resource utilization highly differ between rasagiline and selegiline. There is no homogeneous prescription behaviour among clinicians in preferring one or the other MOAB-I, on the basis of demographic, clinical and therapeutic characteristics of patients with PD.

Prescribing Hydroxyurea in Sickle Cell Disease Patients: The Pattern and Association with Co-Prescribed Medications Used to Manage the Disease Complications.

Background and Objectives: Hydroxyurea (HU) is an effective medication used to reduce the frequency of painful crises associated with sickle cell disease (SCD). However, data describing its prevalence among SCD patients in the Eastern Region of Saudi Arabia are scarce. This is a multi-center, retrospective, cross-sectional study that aims to investigate the pattern of prescribing HU in SCD patients and to determine the association between prescribing HU and other co-prescribed medications used to manage SCD complications. Methods: Data were collected from patients who visited the hematology clinics of Al-Qatif Central Hospital (QCH) and King Fahad Hospital in Hofuf (KFHH) between June 2021 to May 2023. The data included demographics, prescribed medications, and recent laboratory test results, all of which were collected from patients' medical records. Descriptive statistics were utilized to assess the difference between HU users vs. non-users. A binary logistic regression model was used to determine the association between prescribing HU and co-prescribed medications used to manage SCD complications. The results are presented as the odds ratio (OR) and 95% confidence interval (95% CI). Results: This study included 2816 SCD patients with a 56% prevalence of HU prescription. HU was prescribed for young age groups more often compared to old age group patients. Young males were more likely to be prescribed with HU compared to females, and it becomes dominant in females after the age of 36. HU users were more likely to have paracetamol (69% vs. 53%, OR = 1.9, 95% CI 1.6-2.2), NSAIDs (50% vs. 35%, OR = 1.7, 95% CI 1.5-2), and opioids (41% vs. 37%, OR = 1.3, 95% CI 1.1-1.6) co-prescribed, and less often to have laxatives (8% vs. 5%, OR = 0.66, 95% CI 0.48-0.9) and anticoagulants (22% vs. 15%, OR = 0.56, 95% CI 0.46-0.68) co-prescribed compared to non-users. Conclusions: The pattern of prescribing HU, supported by the association findings, raises concerns about patients' compliance and adherence to HU therapy. Early health education, specifically to young female SCD patients, is warranted to increase the success rate of HU therapy.

USANZ: Time-trends in use and impact on outcomes of perioperative chemotherapy in patients treated with radical cystectomy for urothelial bladder cancer.

OBJECTIVE: To review time-trends in the use of perioperative chemotherapy and its impact on oncological outcomes in patients with bladder urothelial cancer (UC) at a single tertiary institution. PATIENTS AND METHODS: Using electronic and paper medical records, 89 patients were identified who underwent radical cystectomy with or without perioperative chemotherapy between 2004 and 2011 at Austin Health in Melbourne, Australia. Patient demographics, clinico-pathological characteristics and details of recurrence and death were assessed by retrospective chart review. Survival analysis was carried out using the Kaplan Meier method, with the impact of predictors assessed using Cox proportional hazard models. RESULTS: The median (range) age of this cohort was 65 (37-84) years, and 66 (74%) patients were male. Pathologic features included 68 (76%) pure UC, 21 (24%) mixed UC and 84 (94%) high grade tumours. On clinical staging, 63 (71%) patients had muscle-invasive bladder cancer (cT-stage ≥ T2), of whom 11 (17%) received neoadjuvant chemotherapy, with an increasing trend in use over time. Following radical cystectomy, pT-stage ≥ T3 and/or node positive were identified in 35 (39%) patients, of whom 16 (46%) received adjuvant chemotherapy. In addition, five patients with stage pT2 received adjuvant chemotherapy. Of the total cohort of patients, 31 (35%) suffered recurrences, and 33 died, 27 from urothelial carcinoma. On multivariate analysis, after adjusting for age, pT-stage and pN-stage, perioperative chemotherapy was associated with a significantly lower risk of recurrence [relative risk (RR) 0.41, p < 0.05], but not death from cancer or all causes. CONCLUSIONS: Perioperative chemotherapy, and in particular neoadjuvant chemotherapy, remains relatively under-utilised at our institution despite recent increases. The significant reduction in the risk of recurrence following treatment with perioperative chemotherapy with radical cystectomy highlights the importance of multi-modality treatment in bladder UC. Identifying barriers to more widespread implementation of perioperative chemotherapy is critical for enhancing outcomes in patients with bladder UC.

The pattern of herbal medicines use for breastfeeding mother in Jogonalan, Klaten, Indonesia: a mini survey.

BACKGROUND AND OBJECTIVES: Indonesian society extensively uses herbal medicine due to its abundant natural resources that have been utilized for generations for health purposes. Herbal medicine is also employed by specific community groups, such as breastfeeding mothers, to address issues like low milk production. However, there has yet to be much research conducted on its usage patterns in the Jogonalan District, Klaten Regency, Indonesia. It is crucial to understand this aspect to gain an overview of herbal medicine utilization in the community, thus preserving local's healthy traditional culture and traditions and continuing their development. This study aims to describe the pattern of herbal medicine usage among breastfeeding mothers in the Jogonalan District, Klaten Regency, Central Java Province, Indonesia. METHODS: The quantitative descriptive study conducted as a mini survey to breastfeeding mothers who used herbs, visited minimal three (3) times in integrated service posts for babies/toddlers in the Jogonalan sub-district and agree to overcome the research. Calculating the frequency distribution was used to analyze the study's findings. The advantages and disadvantages of these results are evaluated in relation to the findings of earlier investigations. RESULTS AND CONCLUSIONS: The respondents were dominated housewives (84.4%), aged 20-35 years (71.1%), had secondary education (60.0%), and multiparous (66.7%). The daily use of uyub-uyub as a breast milk enhancer dominates the pattern of herbal medicine use. Papaya leaves, turmeric, and aromatic ginger are further herbal remedies. Nursing mothers' health and fitness and breastfed children's health is other advantages. The only adverse effects reported by three respondents (6.7%) were nausea and dizziness. Breastfeeding mothers can safely utilize evidence-based herbal medicines by increasing their knowledge, consulting with health professionals, and using them under supervision to preserve their use.

Clozapine prescription rates in Southeast Europe: A cross-sectional study.

Introduction: International reports indicate that clozapine is under prescribed. Yet, this has not been explored in Southeast European (SEE) countries. This cross-sectional study investigates clozapine prescription rates in a sample of 401 outpatients with psychosis from Bosnia and Herzegovina, Kosovo by United Nations resolution, North Macedonia, Montenegro and Serbia. Methods: Descriptive analysis was used to explore clozapine prescription rates; daily antipsychotic dosage was calculated and converted into olanzapine equivalents. Patients receiving clozapine were compared to those not receiving clozapine; next those that were on clozapine monotherapy were compared to those who were on clozapine polytherapy regime. Results: It was showed that clozapine was prescribed to 37.7% of patients (with cross-country variation: from 25% in North Macedonia to 43.8% in Montenegro), with average dose of 130.7 mg/daily. The majority of patients on clozapine (70.5%) were prescribed at least one more antipsychotic (the most frequent combination was with haloperidol). Discussion: Our findings suggested that clozapine prescription rate in SEE outpatients is higher than in Western Europe. The average dose is significantly below the optimal therapeutic dosage recommended by clinical guidelines, and clozapine polytherapy is common. This might indicate that clozapine is prescribed mainly for its sedative effect rather than antipsychotic. We hope that this finding will be taken up by relevant stakeholders to address this non-evidence-based practice.

The Pattern of Substance Use and Characteristics of the Individuals Enrolled in Residential Treatment at Selected Rehabilitation Centers in Sri Lanka: A Descriptive Cross-Sectional Study.

Introduction: Substance use becomes censorious when it leads to harmful effects on individuals, their families, and the community. The nature of substance use in Sri Lankan context is poorly understood and empirical evidences are sparse. The study aimed to describe patterns of substance use and characteristics of the individuals enrolled in residential treatment at selected rehabilitation centers in Sri Lanka. Material and methods: A descriptive cross-sectional study was conducted among 205 individuals enrolled in selected rehabilitation centers. Pretested interviewer-administered questionnaire was used to collect data. Data were analyzed using descriptive statistics. Results: Most of the individuals who enrolled in residential treatment at selected rehabilitation centers were unmarried (n = 124, 60.5%), Sinhala (n = 186, 90.7%), Buddhist (n = 166, 81.0%), males (n = 202, 98.5%) and belonged to the young adult age (18-35 years) category (n = 178, 86.8%). All the participants were poly-drug users and cannabis was the most commonly used (n = 183, 89.3%) illicit drug followed by heroin (n = 172, 83.9%), methamphetamine (n = 150, 73.2%) and cocaine (n = 78, 38%). The most (n = 152, 74.1%) problematic substance for life was heroin. Most of the participants (n = 149, 72.7%) had used drugs several times per day. The mean duration of substance use was 7 ± 5 years. Participants (n = 177, 86.3%) reported that the substances were available in their residential areas and their friends (n = 197, 96.1%) were also using the substances. Conclusions: Pattern of substance use and characteristics of the individuals were unique in Sri Lanka and need to be considered when implementing and strengthening the programs for drug prevention and rehabilitation.

Assessment of the Prevalence of the Use of Nasal Decongestants Among the General Population in Saudi Arabia.

Background A topical nasal decongestant (NDC) is widely prescribed in ENT practice and used as self-medication because it is available over the counter, which makes it an easily accessible medication. Due to its common and long-term use, it is associated with serious nasal complications. It is commonly self-administrated in many otolaryngology diseases like the common cold, sinusitis, and acute or chronic rhinitis. The long-term usage of nasal decongestants is associated with significantly increased side effects. Aim To assess the prevalence of the usage of nasal decongestants among the general population in Saudi Arabia ad the pattern of its use. Methodology A questionnaire-based, cross-sectional survey was applied to level all available populations in Saudi Arabia. Participants with ages aged 10 to 60 years old in Saudi Arabia were invited to participate in the survey. Data were collected from participants using a predesigned online questionnaire. The questionnaire included the participant's demographic data, NDC use, and pattern of use. The questionnaire was uploaded online by researchers and their friends using social media platforms. Results A total of 1456 participants completed the study questionnaire. Participants ages ranged from 10 to 60 years with a mean age of 26.9 ± 12.4 years old. Exact 585 (40.2%) participants were males and 1270 (87.2%) were from urban regions. A total of 657 (45.1%) respondents reported using nasal decongestants while 799 (54.9%) did not use NDC. As for the duration of use, 70.8% used NDC for less than five days and 13.5% used it for 5-15 days. The most reported causes of using NDC were nasal obstruction (62.7%) and common cold (25.7%). Conclusions In conclusion, the study revealed that the frequency of using nasal decongestants was common (45.1%) in the study. More efforts should be paid to improve public awareness regarding indications, duration of use, and method of using nasal decongestants to avoid rebound reactions that may affect patients' daily life activities.

Medical masks' and respirators' pattern of use, adverse effects and errors among Portuguese health care professionals during the COVID-19 pandemic: A cross-sectional study.

BACKGROUND: During COVID-19 pandemic, a shortage of surgical masks (Mask) and respirators (Resp) was experienced worldwide. We aimed to assess its pattern of use, adverse effects and user errors by Portuguese health care professionals (HCP). METHODS: A cross-sectional study was conducted through snowball convenience sample, collected by email/ social media to health care organizations. Participants answered an online anonymous survey in March 2021. RESULTS: Mean age of 3052 respondents was 42.1 years old, 83.6% were female and 77.8% provided direct health care to COVID-19 patients. Mean time of use per shift was 6-8 hours in 40.8% of the participants. 28.0% reported never changing it during their shift. Resp use (vs Mask) was more associated with discomfort (58.2% vs 26.8%), affecting task performance (41.5 vs 18.9%) and communication (55.0 vs 40.9%), dyspnea (36.0 vs 14.4%), skin rash (37.5 vs 19.4%) and headache (37.5 vs 19.4%). Frequent user errors included touching the front while in use (70.1% Mask vs 66.3% Resp) and omitting hand hygiene before (61.8% Mask vs 55.0% Resp) or after use (61.3% Mask vs 57.0% Resp). Average number of errors was higher for Mask (4.3), than for Resp (3.2) (all: P < .001). CONCLUSIONS: Most HCP admitted an extended use of Mask/ Resp. Resp were more prone to adverse effects and Mask more prone to errors. Strategies to reinforce good practices should be considered.

Traditional medicine among the community of Gash-Barka region, Eritrea: attitude, societal dependence, and pattern of use.

BACKGROUND: Despite the growing conventional healthcare coverage in Eritrea, traditional medicine (TM) remains an essential source of healthcare service to the population. This study, therefore, aims at exploring the attitude, societal dependence, and pattern of TM use of the Gash-Barka community. METHODS: A cross-sectional study was conducted between December 2018 and January 2019 in Gash-Barka region, one of the six regions of Eritrea. Two-stage stratified cluster sampling design was used to provide representative sample of households. The data collected through face-to-face interview using a structured questionnaire was entered twice and analyzed using CSPro7.2 and SPSS 23, respectively. Both descriptive and analytical analyses were performed to test statistical significance. RESULTS: Of the total 210 participants, 202 completed the interview with a response rate of 96.2%. Almost 97% of the respondents were aware of the general existence of TM. About half of the respondents (47.4%) had visited traditional health practitioners (THPs) at least once in their lifetime. The majority of the respondents claimed their medical condition had been improved (63.2%), were satisfied with the outcome (76.8%), and had not encountered complications (95.2%) due to TM use. Around 40% of the respondents admitted they do not disclose previous TM use to conventional health practitioners. Females are more likely to have had ever visited THPs (AOR = 1.85, CI: 1.01, 3.38) and use TM in the future (AOR = 2.26, CI: 0.92, 5.14) than males. Moreover, those who had visited THPs before (COR = 8.30, CI: 3.25, 21.20) are more likely to use TM as a primary treatment choice and prefer to use TM in the future (AOR = 4.40, CI: 1.97, 9.83) than those who had never visited THPs. About 61% of the total families claimed they had circumcised at least one female child, and 96.8% disclosed they had circumcised at least one male child. Out of which, 89.2% of the circumcisions were done by THPs. CONCLUSION: TM is popular and widely relayed upon by Gash-Barka residents with exposure of children to harmful TM practices. Since the reliance of the community on TM is expected to continue, further representative studies are recommended to inform regulatory interventions and integrate TM into the health system.

Oral Anticoagulant Prescription Trends, Profile Use, and Determinants of Adherence in Patients with Atrial Fibrillation.

BACKGROUND AND PURPOSE: Data on oral anticoagulant (OAC) uptake and pattern of use are limited. Real-life data in patients with atrial fibrillation (AF) are important for understanding patient exposure. A cohort study of new OAC users was built to assess trends of drug use from 2011 to 2017, persistence rate, switching rate, adherence level, and predictors of adherence. METHODS: We built a cohort using the Régie d'Assurance Maladie du Québec (RAMQ) and Med-Echo administrative databases of new adult OAC users within 1 year following hospitalization with a diagnosis of AF. New users of OAC were defined as having no OAC claims in the year before cohort entry. We assessed trends of OAC use; persistence rate, defined as a gap between refills of no longer than two times the duration of the previous prescriptions; and adherence level, defined as the proportion of days covered (PDC) over a 1-year period following initiation. Predictors of nonadherence (PDC less than 80%) were analyzed using logistic regression models. RESULTS: The cohort consisted of 33,311 incident OAC users. Of total OAC claims, the proportions of warfarin claims decreased from 77.9% in 2011 to 12.7% in 2017, with direct oral anticoagulants (DOACs) accounting for 87.3% of claims, of which apixaban and rivaroxaban accounted for 60.1% and 23.4%, respectively, by the end of 2017. One year after OAC initiation, persistence rates ranged from 53% with warfarin to 77% with a high dose of apixaban. Approximately 75% of incident OAC users were considered "adherent" (PDC 80% or more), with a mean PDC of 95.6-98.1%, compared with "nonadherent," with a mean PDC varying between 43.1% and 50.7%. Older age, female sex, higher CHA2 DS2 -VASc score (to predict thromboembolic risk in AF), prior stroke, and treatment with chronic cardiovascular disease drugs were associated with high adherence levels. CONCLUSION: The clinical uptake of DOACs increased over time, accounting for 87.3% of prescriptions in 2017. In our study, 25% of new OAC users presented a low adherence level. Adherence to OACs remains a significant challenge in patients with AF.

Perception, pattern of use, partner support and determinants of uptake of family planning methods among women in rural communities in Southeast Nigeria.

BACKGROUND: Family planning is a cost-effective strategy for achieving population development. Family planning uptake is low in sub-Saharan Africa, including Nigeria. We assessed the perception, pattern of use, partner support and determinants of uptake of family planning methods among married women of reproductive age in rural communities of Ebonyi state. METHODS: This is part of a baseline report of a quasi-experimental study. A total of 484 married women of reproductive age were recruited using multistage sampling method. Four focus group discussions (men and women) and pre-tested semi-structured interviewer-administered questionnaires were used to collect information from the participants. Data were analysed using Statistical Package for Social Sciences (SPSS) version 20 software and thematic analysis. Chi-square test and logistic regression were carried out at 5% significance level. RESULTS: Only 26.2% of respondents were currently using any method of family planning. The most commonly used method was the natural method (57%). Amongst those who reported using artificial methods, 32.7% used condoms, 27.3% used implant while 23.64 and 16.4% used injectables and pills respectively. Predictors of current use of any family planning method were: older age (AOR = 1.7, 95%CI = 1.01-3.00), having more than five children (AOR = 1.7, 95%CI = 1.05-2.83), minimum of secondary level of education for respondent (AOR = 3.3, CI = 1.60-6.96) and their husband/partner (AOR = 2.0, 95%CI = 1.05-3.92). Qualitative findings showed that only few families were using a method of family planning and those who did not practice family planning perceived it to interfere with God's plan for fruitfulness and to be counter-productive to household income due to decreased manpower for agricultural activities. Poor partner involvement and support for family planning was also cited as a deterrent by both male and female participants. CONCLUSIONS: Perception and use of family planning methods is poor in rural communities of Ebonyi state. Improving uptake of family planning methods in these rural communities will require proper demographic targeting as well as debunking fatalistic views, and cultural and religious myths around family planning.

Family physicians' utility of social media: a survey comparison among family medicine residents and physicians.

INTRODUCTION: Social media has become ubiquitous and has brought a dramatic change in health services. Little is known about its use by family physicians and residents for personal or professional purpose. The aim of the current study was to evaluate the utility of social media among family medicine residents and consultants. METHODS: The collection of data was through the use of a five part questionnaire developed by researchers. The questionnaire was delivered to 70 physicians and 100 residents, out of which 132questionnaires were completed, representing a 78 percent response rate. RESULTS: Our findings demonstrate that there was an overall high use of social media. Females used social media more for general education and professional purposes. Men, by contrast, used it more frequently for personal purposes. The participants in this study appeared to consider social media as having several useful dimensions, such as: enabling them to accomplish job tasks, improve job performance, productivity and more effective patient care when using social media. CONCLUSIONS: To date, limited studies have compared social media use among family physicians and residents. This study may serve as an initial step for future studies explaining the pattern of use among physicians.

Pattern of Use of Biosimilar and Originator Somatropin in Italy: A Population-Based Multiple Databases Study During the Years 2009-2014.

PURPOSE: Somatropin [recombinant growth hormone (rGH)] is approved in children and adults for several conditions involving growth disturbances and the corresponding biosimilar is available in Italy since 2006. No population-based data are available on the pattern of rGH use in Italian clinical practice. This study aimed at exploring the pattern of biosimilar and originator rGH use in six Italian centers, where different policy interventions promoted biosimilar use. METHODS: This population-based, drug-utilization study was conducted in the years 2009-2014, using administrative databases of Umbria, Tuscany, and Lazio Regions and Local Health Units of Caserta, Treviso, and Palermo. Naïve rGH users were characterized, and prevalence of use and discontinuation were assessed over time. RESULTS: Among 6,785 patients treated with rGH during the study years, 4,493 (66.2%) were naïve users (males/females = 1.3), mostly affected by GH deficiency. The prevalence of rGH use increased from 2009 to 2010, remaining stable thereafter, but it was heterogeneous across centers (twofold higher prevalence of use in center n.2 than centers n.4 and 1 in 2014). Biosimilar rGH uptake increased over time but was low (7.8% in 2014) and heterogeneous as well. Discontinuation of rGH therapy occurred in 54.0% of naïve users, more frequently in females than males (58.1 vs. 50.9%). During the first year of treatment, discontinuation was frequent (39.9%), but no statistically significant differences were observed in treatment persistence for biosimilar vs. originator rGH (p > 0.05). CONCLUSION: Geographical heterogeneity in the prevalence of rGH use was observed. Similarly, the biosimilar rGH uptake was low and variable across centers. Post-marketing monitoring is required to continuously monitor the benefit-risk profile of rGH, thus guaranteeing greater savings than only promoting lowest cost rGH.

Hydroxyurea therapy in adult Nigerian sickle cell disease: a monocentric survey on pattern of use, clinical effects and patient's compliance.

BACKGROUND: The clinical prospects of hydroxyurea therapy in the management of sickle cell disease (SCD) require evaluation in the Nigerian setting to develop indigenous guidelines. This survey examines the pattern of hydroxyurea therapy, its clinico-haematologic benefits and safety profile in Nigerian SCD subjects. METHODS: A cross sectional pilot survey was carried out among 60 adult SCD subjects over 3 months. Data on clinical phenotypes, relevant haematological parameters and details of hydroxyurea therapy were obtained using a structured questionnaire through an interview process and case file review. RESULTS: The median age was 30 years. Thirty-four (56.7%) of the subjects are aware of hydroxyurea therapy in SCD. Twenty-four (40%) SCD patients had previously used hydroxyurea. Only 4 subjects were fully compliant. Reasons for non-compliance included poor knowledge and lack of funds. In particular, hydroxyurea reduced leucocyte count and increased mean red cell volume (MCV) in compliant subjects. CONCLUSION: Hydroxyurea use is low among Nigerian SCD subjects despite its proven efficacy/clinical prospects in the developed nations. Large scale multicenter studies and clinical trials are needed to form a basis for developing standard local treatment protocol for its use.

Musculoskeletal pain: prescription of NSAID and weak opioid by primary health care physicians in Sweden 2004-2008 - a retrospective patient record review.

PURPOSE: To study the prescription of oral analgesics for musculoskeletal pain by primary care physicians over a 5-year period in Sweden. DESIGN: A retrospective automatic database review of patient records at four primary health care centers. All prescriptions of NSAIDs, weak opioids, and coprescriptions of gastroprotecting medications to patients with musculoskeletal were retrieved for the period January 1, 2004 to November 11, 2008. RESULTS: A total of 27,067 prescriptions prescribed to 23,457 patients with musculoskeletal pain were analyzed. Of all prescriptions, NSAIDs were the most commonly prescribed analgesic comprising 79%, tramadol was the second most commonly prescribed analgesic comprising 9%, codeine the third most (7%), and dextropropoxyphene the fourth (5%). The proportion of NSAIDs and weak opioids and the proportion of the different weak opioids prescribed showed no change over time. The proportion of nonselective and selective NSAIDs prescribed changed; Coxib prescriptions decreased from 9% to 4% of all analgesics prescribed in 2004-2007 with no change in 2008. CONCLUSION: NSAIDs were found to be the dominant class of analgesic prescribed by primary care physicians to patients diagnosed as musculoskeletal pain. No change was observed in the proportion of NSAID and weak opioid prescription over the period studied. Prescription of selective Coxibs decreased and was less than 4% in 2008. The impact on gastrointestinal and cardiovascular adverse effects associated with the extensive prescription of NSAIDS for musculoskeletal pain warrants further analysis.
