Patterns of pain medication usage and self-reported pain in older Irish adults with osteoarthritis: A latent class analysis of data from the Irish Longitudinal Study on Ageing.

BACKGROUND: This study aimed to identify and describe links between pain medication use and self-reported pain among people aged ≥ 50 years with osteoarthritis (OA) in an Irish population, and to examine the relationships between pain, medication usage and socioeconomic and clinical characteristics. METHODS: Secondary data analysis of wave 1 cross-sectional data from The Irish Longitudinal Study on Ageing (TILDA) was undertaken of 1042 people with self-reported doctor-diagnosed OA. We examined use of medications typically included in OA clinical guidelines, including non-opioid analgesics (e.g. paracetamol), topical and oral non-steroidal anti-inflammatory drugs (NSAIDs), opioids and nutraceuticals. Latent Class Analysis (LCA) was used to identify underlying clinical subgroups based on medication usage patterns, and self-reported pain severity. Multinomial logistic regression was used to explore sociodemographic and clinical characteristic links to latent class membership. RESULTS: A total of 358 (34.4%) of the 1042 people in this analysis were taking pain medications including oral NSAIDs (17.5%), analgesics (11.4%) and opioids (8.7%). Nutraceutical (glucosamine/chondroitin) use was reported by 8.6% and topical NSAID use reported by 1.4%. Three latent classes were identified: (1) Low medication use/no pain (n = 382, 37%), (2) low medication use/moderate pain (n = 523, 50%) and (3) moderate medication use/high pain (n = 137, 13%). Poorer self-rated health and greater sleep disturbance were associated with classes 2 and 3; depressive symptoms and female gender were associated with class 2, and retirement associated with class 3. CONCLUSIONS: Whilst pain medication use varied with pain severity, different medication types reported broadly aligned with OA guidelines. The two subgroups exhibiting higher pain levels demonstrated poorer self-rated health and greater sleep disturbance.

A non-randomised pilot study of the Solutions for Medication Adherence Problems (S-MAP) intervention in community pharmacies to support older adults adhere to multiple medications.

BACKGROUND: Older patients prescribed multiple medications commonly experience difficulties with adherence. High-quality evidence on interventions targeting older patients is lacking. Theory is rarely used to tailor adherence solutions. This study aimed to pilot test a novel intervention, developed using the Theoretical Domains Framework, which guides community pharmacists in identifying adherence barriers and delivering tailored solutions (behaviour change techniques). Key study procedures (e.g. recruitment, data collection) for a future randomised controlled trial (cRCT) were also assessed. METHODS: Using purposive sampling, this non-randomised pilot study aimed to recruit 12 community pharmacies (six in Northern Ireland; six in London, England). Pharmacists were trained to deliver the intervention to non-adherent older patients (maximum 10 per pharmacy; target n = 60-120) aged ≥ 65 years (reduced to 50 years due to recruitment challenges) and prescribed ≥ 4 regular medicines. The intervention, guided by an iPad web-application, was delivered over 3-4 face-to-face or telephone sessions, tailored to specific barriers to adherence. We assessed the feasibility of collecting adherence data (primary outcome: self-report and dispensing records), health-related quality of life (HRQOL) and unplanned hospitalisations (secondary outcomes) at baseline and 6-months. The final decision on progressing to a cRCT, using pre-defined 'stop-amend-go' criteria, is presented. RESULTS: Fifteen pharmacists from 12 pharmacies were recruited and trained. One pharmacy subsequently dropped out. Sixty patients were recruited (meeting the 'Amend' progression criteria), with 56 receiving the intervention. Adherence barriers were identified for 55 patients (98%) and a wide range of behaviour change solutions delivered (median: 5 per patient). Self-report and dispensing adherence data were available for 37 (61.7%) and 44 (73.3%) patients, respectively. HRQOL data were available for 35 (58.3%) patients. GP-reported and self-reported hospitalisations data were available for 47 (78.3%) and 23 (38.3%) patients, respectively. All progression concepts were met (nine 'Go' and three 'Amend' criteria). CONCLUSION: This study demonstrates the feasibility of key study procedures (e.g. pharmacy recruitment) and delivery of a tailored adherence intervention in community pharmacies. However, modifications are required to enhance issues identified with patient recruitment, retention and missing data. A future definitive cRCT will explore the effectiveness of the intervention.

A pilot study of the S-MAP (Solutions for Medications Adherence Problems) intervention for older adults prescribed polypharmacy in primary care: study protocol.

BACKGROUND: Adhering to multiple medications as prescribed is challenging for older patients (aged ≥ 65 years) and a difficult behaviour to improve. Previous interventions designed to address this have been largely complex in nature but have shown limited effectiveness and have rarely used theory in their design. It has been recognised that theory ('a systematic way of understanding events or situations') can guide intervention development and help researchers better understand how complex adherence interventions work. This pilot study aims to test a novel community pharmacy-based intervention that has been systematically developed using the Theoretical Domains Framework (12-domain version) of behaviour change. METHODS: As part of a non-randomised pilot study, pharmacists in 12 community pharmacies across Northern Ireland (n = 6) and London, England (n = 6), will be trained to deliver the intervention to older patients who are prescribed ≥ 4 regular medicines and are non-adherent (self-reported). Ten patients will be recruited per pharmacy (n = 120) and offered up to four tailored one-to-one sessions, in the pharmacy or via telephone depending on their adherence, over a 3-4-month period. Guided by an electronic application (app) on iPads, the intervention content will be tailored to each patient's underlying reasons for non-adherence and mapped to the most appropriate solutions using established behaviour change techniques. This study will assess the feasibility of collecting data on the primary outcome of medication adherence (self-report and dispensing data) and secondary outcomes (health-related quality of life and unplanned hospitalisations). An embedded process evaluation will assess training fidelity for pharmacy staff, intervention fidelity, acceptability to patients and pharmacists and the intervention's mechanism of action. Process evaluation data will include audio-recordings of training workshops, intervention sessions, feedback interviews and patient surveys. Analysis will be largely descriptive. DISCUSSION: Using pre-defined progression criteria, the findings from this pilot study will guide the decision whether to proceed to a cluster randomised controlled trial to test the effectiveness of the S-MAP intervention in comparison to usual care in community pharmacies. The study will also explore how the intervention components may work to bring about change in older patients' adherence behaviour and guide further refinement of the intervention and study procedures. TRIAL REGISTRATION: This study is registered at ISRCTN: 10.1186/ISRCTN73831533.

The mid-forearm arteriovenous fistula as vascular access for haemodialysis

Successful chronic haemodialysis requires permanent vascular access. The Scribner procedure which utilizes an external arteriovenous shunt, the internal synthetic arteriovenous shunt and the direct arteriovenous fistula as described by Cimino and Brescia have all been used for haemodialysis. Of the three methods, the arteriovenous fistula is the most trouble-free and durable. However, as originally described and constructed in the distal forearm, the morbidity associated with this method is significant. The cubital fossa fistula has even more problems. The mid-forearm fistula was designed by the authors and has been used for chronic haemodialysis over the past eighteen years. This article compares the various methods of access used in the haemodialysis units of the University Hospital of the West Indies and the Kingston Regional Hospital. The mid-forearm fistula was found to have the lowest initial failure rate and was associated with fewer complications than any of the other methods used for access.

Hidradenitis suppurativa of the perineum, scrotum, and gluteal area: presentation, complications, and treatment.

Hidradenitis suppurativa is an infrequent inflammatory process that begins as an infection in the apocrine sweat glands. From an initial focus, the infection spreads to involve other tissues of the skin and adjacent structures. When inadequately treated or neglected, the disease becomes chronic with suppuration, sinus formation, invasion of adjacent organs, and occasional malignant degeneration. Social and occupational dislocations are the rule. The peak incidence of the disease is in the third and fourth decades. Blacks and women are most often affected.Our clinical experience with hidradenitis of the scrotum, perineum, and gluteal area is presented. One patient had an associated adenocarcinoma and another had osteomyelitis. All but one had neglected the disease. Emphasis is placed on early and appropriately wide excisional therapy for the disease in all its manifestations. Incision and drainage and antibiotics are of limited value and are best used as preliminaries to definitive excisional therapy.

Scrotal lymphedema praecox: disease and treatment.

Lymphedema of the scrotum and penis represents a debilitating but uncommon entity in countries spared of endemic filariasis. The clinical presentation and surgical management of one patient with idiopathic lymphedema praecox is discussed. A posterior based scrotal skin flap and a split thickness skin graft were used to reconstruct the scrotum and resurface the penis following radical excision of the edematous tissue. Limitation of the disease to the superficial tissues and relative sparing of the posterior scrotal skin represent the anatomic basis for success with this approach. The more deforming therapeutic alternative of excision of all lymphedematous tissue with transfer of the testes to the thigh and split thickness skin grafting to the exposed area would probably be best reserved for recurrence.
